Objective To observe the efficacy and safety of sildenafil in one case of PoPH patients. Methods A case of PoPH patient who was successfully treated with sildenafil was retrospectively analyzed，and literatures related sildenafil and PoPH were reviewed. Results A case of PoPH patient admitted with dyspnea on extetion was diagnosed with echocardiography，gastroscrope and other examinations. She was treated with sildenafil and responded well by decreased pulmonary arterial pressure，improved exercise tolerance and life quality，without obvious side effects. Literatures review suggested that PoPH is an under-recognized but life-threatening complication of cirrhosis or noncirrhotic portal hypertension with poor prognosis which exists in decompensated chronic liver diseases patients. The most classic symptoms of PoPH is progressive dyspnea on extertion. PoPH patients may benefit from sildenafil therapy with decreased pulmonary arterial pressure and improved life quality. Conclusions Theawareness of PoPH should be increased and Sildenafil may be effective and safe for PoPH patients. However，more evidences from clinical trials are needed.
ObjectiveTo investigate the predicting effect of PIK3CA mutations for the efficacy and prognosis of hepatocellular carcinoma (HCC) patients received surgical resection. MethodsPCR and DNA sequencing were used to detect the PIK3CA mutation status of 79 HCC tissues, its impact on the short and long term effects of the patients were analyzed. ResultsIn this group of patients, mutation rate of PIK3CA gene exon 9 was 39.24% (31/79), PIK3CA mutation rate correlated with lymph node status and tumor differentiation (P < 0.05). The therapeutic effect of patients with PIK3CA mutation was significantly poor than that of the non-mutated group (P < 0.05). The three-year cumulative survival of patients with PIK3CA mutation (33.33%) was significantly lower than non-mutated group's (60.00%) by Kaplan-Meier (P < 0.05). ConclusionPIK3CA gene mutation in exon 9 could impact the efficiency of surgical resection in patients with HCC and could predict a poor survival prognosis.
ObjectiveTo observe the efficacy of intravitreal injection of conbercept (IVC) combined with subthreshold micropulse laser photocoagulation (SMLP) in the treatment of diabetic macular edema (DME). MethodsA randomized controlled trial. From December 2020 to January 2022, 100 patients (100 eyes) with DME diagnosed by examination in Shanxi Aier Eye Hospital were included in the study. The patients were randomly divided into IVC group (50 eyes) and IVC+SMLP group (50 eyes). All the eyes were treated with IVC once a month for 3 times, and the eyes in IVC+SMLP group were treated with SMLP within 2 weeks after IVC. All affected eyes were examined by best corrected visual acuity (BCVA), which was statistically converted to logarithm of the minimum angle of resolution (logMAR) visual acuity. The central macular thickness (CMT) was measured by optical coherence tomography. Before the treatment, the logMAR BCVA of patients in IVC group and IVC+SMLP group were 0.56±0.04 and 0.55±0.03, respectively. The CMT were (437.36±11.35) μm and (434.58±10.88) μm, respectively. There was no significant difference in logMAR BCVA and CMT between the two groups (t= 0.476, 1.027; P＞0.05). The patients were followed up for 12 months after treatment. The times of IVC and the changes of BCVA and CMT were compared between the two groups. Independent sample t-test was used to compare the logMAR BCVA, CMT and times of IVC between groups. ResultsAfter 12 months treatment, the logMAR BCVA of IVC group and IVC+SMLP group were (241.63±29.79) μm and (240.47±30.46) μm, respectively. Compared with those before treatment, 12 months after treatment, the BCVA of the two groups increased significantly (t=7.014, 5.608; P＜0.001), while CMT decreased significantly (t=8.126, 6.013; P＜0.001). There was no significant difference in BCVA and CMT between the two groups (t=0.835, 0.764; P＞0.05). The number of IVC in IVC group and IVC+SMLP group were (8.15±2.04) times and (5.91±1.80) times, respectively, and the difference was statistically significant (t=5.210, P＜0.001). ConclusionsBoth IVC+SMLP and IVC alone can effectively reduce CMT and increase BCVA in patients with DME. Combination therapy can reduce the number of IVC.
ObjectiveTo evaluate the clinical efficacy of medical absorbent pads in the treatment of wouds. MethodsA total of 200 patients treated in the Wound Treating Center of a first-class hospital between November 2014 and August 2015 were randomly divided into trial group and control group with 100 patients in each. Patients in the trial group received medical absorbent pads, while patients in the control group received the treatment of Zetuvitò E. All patients received four times of treatment. Then we used self-made observation record form to evaluate such indexes as water absorption and compliance of the dressing, patients' pain and secondary trauma scores and the score of skins around the wounds. ResultsThere was no significant difference in water absorption property and compliance between the two groups (P>0.05). But the score of visual analogue scale was lower in the trial group than that in the control group at the fourth dressing changing (P<0.05), and the score of secondary trauma was also lower in the trial group than that in the control group at the third and fourth dressing changing (P<0.05). ConclusionThe medical absorbent pads used in the trial group can relieve pain and promote wound healing. It can be used for the treatment of wounds, and also has better effectiveness and safety.
Objectives To conduct a meta-analysis to evaluate the efficacy and safety of thymosin-α1 for HBeAg-positive chronic hepatitis B. Methods We searched MEDLINE, Science Citation Index, Current Content Connect, Cochrane Controlled Trial Register and Chinese Biomedical Database (CBMdisc) to September 15, 2005, and screened the references of eligible trials by hand-searching. Randomized controlled trials (RCTs) comparing thymosin-α1 with non-antiviral interventions (placebo, no treatment and standard care) in patients with HBeAg positive chronic hepatitis B were eligible for inclusion. We conducted quality assessment and data extraction by two independent investigators with disagreement resolved by discussion. We used chi-square test and Galbraith plot to detect the heterogeneity, and used fixed (Mantel-Haenzel) and random effect model (DerSimonian-Laird) to pool the trials. When the results in two models differed, the results of random effect were reported. Subgroup analysis was performed to detect whether the duration affected the efficacy of thymosin. Results Four RCTs were included. It was found that the rate of loss of HBeAg was 38.8% in thymosin, significantly higher than that of 12.4% in control groups (RR 2.22, 95%CI 1.55 to 3.21, P=0.000). Loss of HBV-DNA was 36.9% in thymosin-α1, significantly higher than that of 13.8% in control groups (RR 2.18, 95%CI 1.50 to 3.17, P=0.000). Both short-duration (8-13 weeks) and regular duration (26-52 weeks) of thymosin-α1 achieved higher loss of HBeAg and HBV-DNA. The complete response rate was 32.3% in thymosin-α1, significantly higher than the control, 11.3% (RR 2.91, 95%CI 1.71 to 4.94, P=0.000). No statistical significance was found for HBeAg seroconversion and ALT normalization. No significant adverse drug reactions were found. Conclusions Thymosin-α1 might be efficacious in loss of HBeAg and HBV-DNA, and complete response for patients with HBeAg-positive chronic hepatitis B. Little evidence was available on HBeAg seroconversion, normalization of ALT, loss of HBsAg, and histological response. Further high-quality RCTs were needed for confirmation.
Objective To explore the short-term efficacy and safety of intra-arterial thrombolysis (IAT) in the treatment of retinal artery occlusion (RAO) with the assistance of the rescue green channel in the eye stroke center. Methods A prospective, interventional, single-center study. Thirty-eight eyes from 38 RAO patients who received IAT treatment in Guangdong Provincial People’s Hospital were enrolled. All the patients were rescued via the green channel in our eye stroke center. Data from comprehensive ocular examinations including best-corrected visual acuity (BCVA) and optical coherence tomography angiography (OCTA) were collected. BCVA was measured with Snellen chart and converted to the logarithmic minimum angle of resolution (logMAR) unit for statistical analysis. RTVue XR OCTA was used to measure vascular densities (VD) of the superficial capillary plexus (SCP), deep capillary plexus (DCP) and radial peripapillary capillary (RPC), and central retinal thickness (CRT). All RAO eyes attempted IAT treatment and 34 eyes were successful. Four eyes failed to complete IAT because of the occlusion of internal or common carotid arteries on the same side with the RAO eyes. Ocular examinations in post-operative 1-3 days were performed with the same devices and methods as those before surgery. Parameters measured before and after surgery include BCVA, VD of SCP, DCP, RPC, and CRT. Data of the green channel collected include the time intervals from onset of RAO to first presentation in local hospitals, and from onset of RAO to our eye stroke center. Comparisons of VD and CRT between the RAO eyes and contralateral healthy eyes were performed with independent samples Mann-Whitney U test; comparisons of VD and CRT in RAO eyes before and after IAT surgery were performed with paired samples Wilcoxon Rank Sum test. Results Among the 34 RAO patients who had successful IAT surgery, 18 (52.9%, 18/34) were males and 16 (47.1%, 16/34) were females; the mean age was (51.0±12.9) years old. There were 30 and 4 eyes diagnosed as central RAO and branch RAO respectively. The logMAR BCVA before and after IAT surgery was 2.52±0.61 and 2.18±0.85 respectively, and the difference was statistically significant (Z=－3.453, P=0.002). Before surgery, VD of SCP, DCP and RPC were significantly decreased and CRT was significantly increased in the affected eye compared with the contralateral healthy eyes, with the statistical significance (P＜0.001). Compared with those before surgery, the VD of SCP and DCP were significantly improved after surgery (Z=－2.523, －2.427; P=0.010, 0.014), while there was no difference in VD of RPC and CRT (Z=－1.448, －1.454; P=0.150, 0.159). The time interval between onset of RAO and first visit to the hospital was (6.56±6.73) hours; the time interval between onset of RAO and the arrival at our hospital was (24.11±19.90) hours. No cerebral stroke was observed in the early post-operative period and no cerebrocardiovascular events were observed later. he time interval between onset of RAO and the arrival at our hospital was (24.11±19.90) hours. No cerebral stroke was observed in the early post-operative period and no cerebrocardiovascular events were observed later. Conclusions The short-term efficacy and safety of IAT in the treatment of RAO were satisfactory. The rescue time window might be prolonged.
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 investigate the efficacy and safety of neo-adjuvant chemotherapy for stage ⅠB2-ⅡB cervical cancer. Methods From June 2012 to December 2014, 66 patients with stage ⅠB2-ⅡB cervical cancer were selected and treated by PT (cisplatin/ carboplatin and taxol/docetaxel) as neo-adjuvant chemotherapy prior to surgery. Neo-adjuvant chemotherapy response and toxicity were collected and analyzed. Results The extinctive condition of tumor by neo-adjuvant chemotherapy: the complete remission rate was 10.6% (7/66), partial remission rate was 59.1% (39/66), and the total effective rate was 69.7%. The main toxicities were myelosuppression (59.1%, 39/66) and gastrointestinal reactions (33.3%, 22/66). The toxicities could be tolerated or relieved by prevention and treatment. The effective rate of chemotherapy for cervical squamous cell carcinoma, adenocarcinoma, adenosquamous carcinoma was 72.6%, 33.3% and 0%, respectively, with significant differences among the three types (P<0.05). The effective rate of chemotherapy for high, medium and low differentiated cervical cancer was 100.0%, 77.3% and 55.9%, respectively, with significant differences among the three degrees (P<0.05). Conclusions Neo-adjuvant chemotherapy is proved to be a safe and effective complementary treatment for most patients with locally advanced cervical cancer. Due to the limitation of sample size, the correlations between therapeutic effect and tumor differentiation degree and between therapeutic effect and pathological type need further study.
Objective To assess the efficacy and safety of levoamlodipine besylate for essential hypertension. Methods We searched MEDLINE (1999 to October 2007), EMBASE (1999 to October 2007), The Cochrane Library (Issue 3, 2007), CNKI (1999 to 2007), Wanfang (1999 to 2007), VIP (1999 to 2007) and CBM (1999 to October 2007). The quality of included studies was critically evaluated. Data analyses were performed with The Cochrane Collaboration’ s RevMan 4.2 software. Results A total of 345 articles were retrieved, but only 17 were finally included. Meta-analyses showed that the effective rate in patients receiving levoamlodipine besylate was significantly higher than that in patients receiving indapamide (RD 0.14, 95%CI 0.06 to 0.22, P=0.0004), while no significant differences were noted between the levoamlodipine besylate group and other control groups. The incidence of adverse effects was significantly lower in the levoamlodipine besylate group compared to the indapamide group (RD –0.12, 95%CI –0.21 to –0.03, P=0.01), the amlodipine group (RD –0.06, 95%CI –0.11 to –0.01, P=0.02) and the nitrendipine group (RD –0.27, 95%CI –0.46 to – 0.08, P=0.006). No significant differences were observed between the levoamlodipine besylate group and other control groups. Conclusion Levoamlodipine besylate tends to have better efficacy and safety profiles compared with other antihypertensive drugs. However, most trials included in the review were of poor quality and, so, multi-center large-scale randomized controlled trials of higher quality are needed to confirm this.
ObjectiveTo explore the efficacy of da Vinci robotic surgical system-assisted radical resection of rectal cancer. MethodsThe clinical data of 456 patients who received radical resection of rectal cancer by the da Vinci robotic surgical system at the Southwest Hospital from March 2010 to March 2016 were retrospectively analyzed. Operative time, operative blood loss, number of harvested lymph nodes, hospital stay, and morbidity were evaluated. Resultsda Vinci robotic surgical system-assisted radical resection of rectal cancer were successfully carried out in 445 patients, and other 11 patients were converted to open surgery (2.4%). Of 456 patients, 322 patients underwent anterior resection of rectum procedure (70.6%), 126 patients underwent abdominoperineal excision procedure (27.6%), 8 patients underwent Hartmann procedure (1.8%). The mean operative time was (192±60) min, the mean operative blood loss was (110±93) mL, the mean number of harvested lymph nodes were 19±6, the mean length between distal resection margin and tumor were (3.5±1.8) cm, the mean time for patients taking normal activity was (2.9±1.5) d, the mean time of passage of the first flatus was (2.7±1.7) d, the mean hospital stay was (7.1±1.6) d. Surgical complications occurred in 40 patients (8.8%), and all the patients were recovery before leaving hospital. The mean follow-up time was 29.1-month (3-75 months). There were 70 patients suffered from occurrence or metastasis (16.2%), and 60 patients died (13.9%). Conclusionda Vinci robotic surgical system-assisted radical resection for rectal cancer is a feasible and safe surgical procedure with the minimal trauma, fast recovery, and satisfactory clinical efficacy.
