Objective To evaluate the efficacy of intravertebral analgesia for external cephalic version. Methods We electronically searched The Cochrane Library (Issue 4, 2009), PubMed (1980 to 2009), Ovid MEDLINE (1950 to 2009), Ovid EBM Database (1991 to 2009), EMbase (1980 to 2009), CBM (1978 to 2009) and CNKI (1979 to 2009) to collect literature about intravertebral analgesia for external cephalic version. We screened randomized controlled trials (RCTs) according to the predefined inclusion and exclusion criteria, extracted data and evaluated the quality of the included studies, and then performed meta-analyses by using RevMan 5.0.13 software. Results Seven RCTs involving 620 women met the inclusion criteria. Five trials were of relatively high quality, and 1 of low quality and 2 not clear. The result of meta-analyses showed that intravertebral analgesia was superior in external cephalic version with a RR 1.53 and 95%CI 1.24 to 1.88. Conclusion Intravertebral analgesia can increase the successful rate of external cephalic version in the treatment of breech presentation compared with intravenous medicine for systematic use or no analgesia.
ObjectiveTo compare the early efficacy between Quadrant channel and traditional method in treating lumbar disc herniation. MethodBetween July 2010 and December 2012, 60 patients with lumbar disc herniation were randomly divided into two groups with 30 in each. Quadrant channel and traditional method were used respectively to do the same one single segmental pedicle screw fixation with single pieces of cage bone grafting fusion and internal fixation. Then, we compared the two groups in incision length, operative time, blood loss, incision healing time and postoperative incidence of low back pain between the two groups of patients. ResultsThere were no significant differences between the two groups in terms of operation time, blood loss, and recent curative effect (P>0.05), while Quadrant channel was superior in small skin incision, reduced incidence of low back pain, and shorter postoperative incision healing time (P<0.05). ConclusionsTreatment of lumbar disc herniation using Quadrant channel is minimally invasive with less complications. Mid-and long-term efficacy remains to be further analyzed.
ObjectiveTo systematically review the efficacy and safety of laryngeal mask versus endotracheal tubes for laparoscopic surgery.MethodsPubMed, EMbase, The Cochrane Library, CNKI, WanFang Data and CBM databases were electronically searched to collect the randomized controlled trials (RCTs) about the efficacy and safety of laryngeal mask versus endotracheal tubes for laparoscopic surgery from inception to April, 2017. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 16 RCTs involving 1 593 patients were included. The results of meta-analysis showed that: there was no significant difference in the success rate of the first insertion (RR=0.99, 95%CI 0.96 to 1.02, P=0.55). The airway pressure of patients whose position were head higher than foot was significantly lower in the laryngeal mask group than in the tracheal intubation group (MD=–1.20, 95%CI –1.81 to –0.59, P=0.000 1), but there was no significant difference between two groups in reverse position patients (MD=0.48, 95%CI –0.90 to 1.87, P=0.49). The incidence of sore throat (RR=0.58, 95%CI 0.46 to 0.74, P<0.000 01), the incidence of blood stain (RR=0.48, 95%CI 0.30 to 0.77, P=0.002), the incidence of laryngeal spasm/bronchial spasm (OR=0.30, 95%CI 0.11 to 0.80, P=0.02) and the incidence of cough/hiccup (RR=0.10, 95%CI 0.07 to 0.15, P<0.000 01) in the laryngeal mask group were significantly lower than those in the tracheal intubation group.ConclusionThe current evidence shows that compared with tracheal intubation, laryngeal mask can effectively reduce airway pressure of patients whose position are head higher than foot. The risks of various complications are significant higher in tracheal intubation in laparoscopic surgery. Laryngeal mask can maintain patients' normal respiratory functions while reduce damage and do not increase the occurrence of reflux aspiration. Due to limited quantity and quality of the included studies, more high quality studies are needed to verify above conclusion.
ObjectiveTo systematically review the efficacy and safety of dexamethasone in the treatment of viral myocarditis.MethodsThe Cochrane Library, PubMed, EMbase, Biosis Preview, Web of Science, CBM, WanFang Data, VIP, and CNKI databases were electronically searched to collect randomized controlled trials (RCTs) on dexamethasone for patients with viral myocarditis from inception to April 30th, 2021. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of the included studies. Meta-analysis was then performed using RevMan 5.4 software.ResultsA total of 7 RCTs involving 749 patients were included. The results of meta-analysis showed that the dexamethasone treatment group exhibited an increased efficacy rate (RR=1.26, 95%CI 1.18 to 1.34, P<0.000 01), decreased levels of C-reactive protein (CRP) (MD=−11.49, 95%CI −19.25 to −3.72, P=0.004), cardiac troponin I (cTnI) (MD=−26.14, 95%CI −40.82 to −11.47, P=0.0005), and creatine kinase MB (CK-MB) (MD=−20.06, 95%CI −28.35 to −11.77, P<0.000 01), and a decreased adverse event rate (RR=0.40, 95%CI 0.24 to 0.65, P=0.000 3).ConclusionsCurrent evidence shows that dexamethasone can significantly improve the efficacy rate, reduce the levels of CRP, cTnI, and CK-MB, and reduce the incidence of adverse events in patients with viral myocarditis. Due to the limited quantity and quality of included studies, more high-quality studies are required to verify above conclusions.
ObjectiveTo provide an overview of systematic reviews on the efficacy and safety of massage for the treatment of cervical spondylotic radiculopathy.MethodsCNKI, WanFang Data, VIP, CBM, PubMed, The Cochrane Library and EMbase databases were electronically searched to collect the systematic reviews on the efficacy and safety of massage for the treatment of cervical spondylotic radiculopathy from inception to December 30th, 2018. Two reviewers independently screened the literature and extracted the data, applied the AMSTAR2 scale to evaluate its methodological quality, and GRADE to evaluate the quality of the evidence.ResultsA total of 7 systematic reviews/meta-analysis were included. The AMSTAR2 scale evaluation showed that the quality of the included studies was extremely low. The GRADE evidence grading results showed that the quality of the VAS score outcome index of the two literatures was intermediate, and the quality of the OASCSR outcome index of one literature was intermediate. The quality of the remaining outcome indicators reported is low or very low.ConclusionThe available evidence shows that the efficacy and safety of manual treatment of cervical spondylotic radiculopathy is acceptable, but the overall methodological quality of the systematic review is extremely low, and the quality level of evidence is generally low. The future clinical trials and systematic reviews should be strictly followed. The scientific research design of the medical science provides high-quality evidence and provides reference for clinical practice.
Objective To systematically review the efficacy and safety of umeclidinium/vilanterol in the treatment of chronic obstructive pulmonary disease. Methods PubMed, The Cochrane Library, WanFang Data, CNKI and VIP databases were electronically searched to collect randomized controlled trials (RCTs) about umeclidinium/vilanterol for chronic obstructive pulmonary disease from inception to March 2017. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, meta-analysis was performed using RevMan 5.3 software. Results Eight RCTs involving 8 992 patients were included. The results of meta-analysis showed that: (1) umeclidinium/vilanterol vs. placebo: umeclidinium/vilanterol could significantly improve Trough FEV1 (MD=0.20, 95%CI 0.17 to 0.23, P<0.000 01) and the quality of life: TDI score (MD=0.99, 95%CI 0.71 to 1.28,P<0.000 01), SGRQ score (MD=–4.00, 95%CI –5.35 to –2.66,P<0.000 01), SOBDA score (MD=–0.16, 95%CI –0.23 to –0.09,P<0.000 01), and reduce the use of rescue drugs (salbutamol), while not increase the adverse events. (2) umeclidinium/vilanterolvs. fluticasone propionate/salmeterol: UMEC/VI could improve lung function in patients with COPD: Trough FEV1 (MD=0.09, 95%CI 0.07 to 0.11, P<0.000 01), reduce the use of rescue drugs (salbutamol), and had lower adverse events. But there was no significant difference in the quality of life between two groups. (3) umeclidinium/vilanterolvs. single bronchodilator: umeclidinium/vilanterol could significantly improve spirometric parameters: Trough FEV1 (MD=0.08, 95%CI 0.07 to 0.10, P<0.000 01), and the quality of life: TDI score (MD=0.38, 95%CI 0.17 to 0.59,P=0.000 3), SGRQ score (MD=–1.18, 95%CI –2.06 to –0.29, P=0.009). Umeclidinium/vilanterol could significantly reduce the use of rescue drugs (salbutamol) without increasing the adverse events. Conclusion UMEC/VI is superior to placebo in the treatment of COPD patients, which can significantly improve lung function, control symptoms and improve the quality of life, with good safety and tolerance. Compared with salmeterol/fluticacin, UMEC/VI has a significant effect on improving lung function and controlling symptoms without increasing adverse effects, while UMEC/VI is easier to use with better patient compliance. UMEC/VI is superior to bronchodilator alone in improving lung function, controlling symptoms and improving the quality of life without increasing the incidence of adverse events. Due to limited quality and quantity of the included studies, more high-quality studies are required to verify above conclusions.
Objective To systematically review the efficacy and safety of laparoscopic hepatectomy (LH) and open hepatectomy (OH) for patients with hepatocellular carcinoma (HCC). Methods PubMed, EMbase, The Cochrane Library, CBM, WanFang Data, CNKI databases were electronically searched to collect the case-control studies about LH vs. OH for patients with HCC from inception to December, 2015. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then meta-analysis was performed by using RevMan 5.3 software. Results A total of 28 studies involving 1 908 patients were included. The results of meta-analysis showed that: the LH group was superior to OH group on complications (OR=0.35, 95%CI 0.26 to 0.48, P<0.000 01), hospital stay (MD=–4.18, 95%CI (–5.08, –3.29),P<0.000 01), and five years overall survival rate (OR=1.65, 95%CI 1.23 to 2.19,P=0.000 7) and disease-free survival rate (OR=1.51, 95%CI 1.12 to 2.03, P=0.006). However, no significant differences were found in one year and three years overall survival rate, disease-free survival rate, and postoperative recurrence rate. Conclusion Current evidence shows that the LH is superior to OH for the treatment of HCC, and may be amenable to surgery because of its safety and longtime efficacy. Due to limited quality and quantity of the included studies, more high quality studies are needed to verify above conclusion.
Objective To systematically review the efficacy and safety of abiraterone acetate in the treatment of castration-resistant prostate cancer. Methods CNKI, WanFang Data, VIP, Web of Science, PubMed, EMbase and The Cochrane Library databases were electronically searched to collect randomized controlled trials on abiraterone in the treatment of castration-resistant prostate cancer from inception to December 31st, 2020. Two reviewers independently screened literature, extracted data and evaluated the risk of bias of the included studies. Meta-analysis was then performed using RevMan 5.3 software. Results A total of 25 randomized controlled trials involving 8 654 patients were included. Meta-analysis results showed that the median radiographic progression-free survival (MD=5.81, 95%CI 3.58 to 8.03, P<0.01), PSA response rate (RR=2.77, 95%CI 1.65 to 4.65, P<0.01), median overall survival (MD=6.44, 95%CI 4.54 to 8.33, P<0.01), median time to PSA progression (MD=2.57, 95%CI 1.30 to 3.84, P<0.01), median PSA progressionfree survival (MD=6.74, 95%CI 5.08 to 8.39, P<0.01), testosterone level control (MD=−0.41, 95%CI −0.68 to −0.14, P<0.01), PSA level control (MD=−8.06, 95%CI −13.82 to −2.31, P<0.01), effective rate (RR=2.94, 95%CI 1.89 to 4.58, P<0.01), complete remission (RR=1.66, 95%CI 1.02 to 2.72, P<0.05), granulocytopenia (RR=0.18, 95%CI 0.07 to 0.45, P<0.01) and KPS score (MD=4.29, 95%CI 4.06 to 4.52, P<0.01) were significantly superior to non-abiraterone treatment group. The incidence of hypertension (RR=2.04, 95%CI 1.62 to 2.57, P<0.01), heart disease (RR=2.27, 95%CI 1.80 to 2.86, P<0.01) and hypokalemia (RR=2.89, 95%CI 1.59 to 5.26, P<0.01) adverse reactions were significantly higher than those in non-abiraterone group. The number of drug withdrawals caused by adverse reactions (RR=1.26, 95%CI 0.98 to 1.61, P>0.05), fluid retention or edema (RR=1.23, 95%CI 0.73 to 2.09, P>0.05), liver function damage (RR=1.66, 95%CI 0.93 to 2.97, P>0.05), fatigue and weakness (RR=0.97, 95%CI 0.73 to 1.29, P>0.05), anemia (RR=0.86, 95%CI 0.64 to 1.16, P>0.05) and elevated blood glucose (RR=1.51, 95%CI 0.96 to 2.36, P>0.05), were not significantly different between the two groups. Conclusion Abiraterone acetate can effectively delay the progression of castration-resistant prostate cancer, prolong the survival period, and improve the quality of life. Due to the limited quantity and quality of the included studies, more high-quality studies are needed to verify the above conclusion.
ObjectiveTo evaluate the clinical efficacy and safety tolerance of perampanel in the treatment of Chinese adult epilepsy patients. Methods Clinical data of adult epileptic patients treated with perampanel in Department of Neurology, China-Japan Union Hospital of Jilin University from January 2020 to December 2022 were analyzed retrospectively by self-control method, including demographic and clinical characteristics of patients, changes of epileptic seizures before and after perampanel treatment and adverse events during the treatment of perampanel. To evaluate the clinical efficacy and safety of perampanel in Chinese adult epileptic patients. Results A total of 69 adult epileptic patients with complete follow-up data were included. The dosage range of perampanel was 2 ~ 8 mg. The total effective rate was 68.1%, and the seizure-free rate was 17.4%. The most common adverse reactions were mood change and dizziness, the incidence of adverse reactions was 52.2%, and the incidence of serious adverse reactions was 0.0%. In terms of analysis of influencing factors of efficacy, the results showed that single drug therapy or combination therapy, type of combined antiepileptic drug and treatment time of perampanel did not affect the efficacy (P>0.05), while dosage was an important factor affecting the efficacy of perampanel (P<0.05), and there was no significant difference in efficacy between the focal epilepsy group and the general epilepsy group (P>0.05). In terms of the analysis of factors related to the occurrence of adverse reactions, the results showed that the occurrence of adverse reactions was related to the dosage of perampanel (P<0.05), and was independent of whether it was monotherapy, the addition time of perampanel and the type of combined antiepileptic agents (P>0.05). Conclusion Perampanel has good efficacy and safety tolerance in the treatment of epilepsy in Chinese adults. Both monotherapy and additive therapy can effectively control seizures, and has a good effect on different seizure types. The most common adverse events during treatment were mood changes and dizziness, which could be alleviated and tolerated by most patients with prolonged treatment.
Objective To systematically review the efficacy and safety of immune checkpoint inhibitors combined with chemotherapy in the treatment of triple-negative breast cancer. Methods The PubMed, Cochrane Library, Embase, Web of Science, CNKI, WanFang Data and VIP databases were searched for randomised controlled trials (RCTs) of immune checkpoint inhibitors combined with chemotherapy versus chemotherapy alone for triple-negative breast cancer from inception to April 1, 2024. Two reviewers independently screened the literature, extracted data, and assessed the risk of bias of the included studies. Meta-analysis was then performed by using RevMan 5.4 software. Results A total of 13 RCTs involving 5 416 patients were included. The results of meta-analysis showed that the pathologic complete response rate (pCR) (OR=2.09, 95%CI 1.37 to 3.19, P<0.01), progression-free survival (PFS) (HR=0.75, 95%CI 0.67 to 0.83, P<0.01) and overall survival (OS) (HR=0.87, 95%CI 0.79 to 0.96, P<0.01) were significantly better than those in the control group. The results of subgroup analysis showed that there were statistically significant differences in PFS (P<0.01) and OS (P=0.02) between PD-L1-positive and PD-L1-negative patients, but there was no statistically significant difference in pCR between PD-L1-positive patients and PD-L1-negative patients (P=0.36). There was a statistically significant difference in pCR between node-positive patients and node-negative patients (P=0.03). There was no statistically significant difference in pCR between patients treated with PD-1 inhibitors and PD-L1 inhibitors (P=0.32); and there was no significant difference in PFS (P=0.19) or OS (P=0.99) between patients treated with PD-1 inhibitors and PD-L1 inhibitors. Compared with those in the control group, the incidences of serious adverse events (RR=1.36, 95%CI 1.09 to 1.70, P<0.01) and immune-related adverse events (RR=2.98, 95%CI 1.66 to 5.35, P<0.01) were higher in the experimental group, and the common immune-related adverse events were hypothyroidism and hyperthyroidism.Conclusion The existing evidence shows that immune checkpoint inhibitors combined with chemotherapy are more effective than chemotherapy alone in the treatment of triple-negative breast cancer, and the combination therapy has a higher incidence of adverse reactions. Due to the limited quantity and quality of the included studies, more high-quality studies are needed to verify the above conclusion.
