ObjectiveTo investigate the clinical effect and the incidence of postoperative complications of Milligan-Morgan hemorrhoids combined with reducing tension of alary incision in the treatment of annular mixed hemorrhoids.MethodsProspectively collected 120 patients with annular mixed hemorrhoids who received treatment from the Department of Colorectal Surgery of Bazhong Hospital of Traditional Chinese Medicinel during the April, 2016 to October, 2018. All of the 120 patients with annular mixed hemorrhoids were randomly divided into the experimental group and the control group, with 60 patients in each one group. Patients in the experimental group was treated with Milligan-Morgan hemorrhoids combined with reducing tension of alary incision, while patients in the control group with conventional Milligan-Morgan hemorrhoid.ResultsIn the experimental group, 49 cases were cured, 11 cases showed obvious effect; in the control group, 39 cases were cured, 20 cases showed obvious effect, and 1 case was effective. The curative effect in experimental groups was better than that of the control group (Z=–2.090, P=0.037), and the effective rates of these two group were both 100% in total. The mean healing time was (19±3) d (14–21 d) in the experimental group and (21±3) d (14–24 d) in the control group, respectively, which was better in the experimental group (Z=–13.636, P<0.001). Experimental group with lower score of wound pain, hemafecia, and anal margin edema, which were much better than control group on 1 d and 3 d after operation (P<0.05). There was no statistically significant differences on incidence of uroschesis and recurrence rate between the two groups (P>0.05).ConclusionsMilligan-Morgan hemorrhoids combined with reducing tension of alary incision in the treatment of annular mixed hemorrhoids has good clinical effect and deserves clinical application.
ObjectiveTo summarize the current treatment status and progress of neoadjuvant chemotherapy for pancreatic cancer in order to improve the understanding of neoadjuvant chemotherapy and to guide clinical work.MethodThe relevant literatures at home and abroad on neoadjuvant chemotherapy for pancreatic cancer were readed and reviewed.ResultsNeoadjuvant chemotherapy could reduce tumor lesions, increase R0 resection rate, decrease postoperative complication rate, and improve patients’ survival, however, there was currently no high quality evidence-based medicine proof. At present, there was no unified neoadjuvant chemotherapy regimens for pancreatic cancer in the world. FOLFIRINOX, gemcitabine plus S-1, and gencitabine plus Nab-paclitaxel were the three common regimens we used. In addition, the neoadjuvant chemotherapy of pancreatic cancer had no uniform standard, and there were insufficient methods for evaluating therapeutic effects.ConclusionAlthough there are still some core problems need to be solved in neoadjuvant chemotherapy for pancreatic cancer, however, it’s curative effect is gradually recognized and widely used by clinicians, which is beneficial to provide a better prognosis for pancreatic cancer patients.
Objective To evaluate the clinical efficacy of fistula repair by stapler technique in patients with cervical tracheoesophageal fistula. Methods Retrospective analysis of 8 patients with cervical tracheoesophageal fistula who accepted operative treatment in the Department of Thoracic Surgery, Lanzhou University Second Hospital from October 2014 to October 2016 was conducted. There were 5 males and 3 females at a mean age of 46.4±13.9 years ranging from 23 to 67 years. The fistula was induced by tracheal intubation in 4 patients, by esophageal foreign bodies in 2, by tracheal stent in 1 and by esophageal diverticulum in 1. The fistula was closed by stapler technique. The surgical effects were evaluated through Karnofsky performance score (KPS), image assessment, patient satisfaction score and assessment of improvement in feeding-induced bucking. Results The operations were performed successfully with time of 117.5±6.6 min and intraoperative blood loss of 60.0±7.0 ml. After the operations, the patients did not suffer incision bleeding and infection, hoarseness, dyspnea, drinking-induced bucking, fistula relapse, tracheoesophageal stenosis or any other complications, and no death occurred during the perioperative period. The chest X-ray test was performed 1 week later showed that the pulmonary infection disappeared, and only 1 patient suffered from esophageal stenosis 1 year later. The postoperative KPS score was 90.0±7.0 points, which significantly improved in contrast to preoperation (P<0.01). Postoperative pulmonary infection area reduced significantly (P<0.05), tracheoesophageal fistula disappeared, postoperative patients satisfaction rate was 90%, and assessment of feeding-induced bucking was excellent. Conclusion Using stapler technique to repair cervical tracheoesophageal fistula is safe, easy and useful, with less operation time and postoperative complications.
Objective To systematically evaluate the efficacy and safety of immune checkpoint inhibitors (ICIs) as first-line treatment for advanced non-small cell lung cancer (NSCLC). MethodsPubMed, The Cochrane Library, and EMbase databases were searched for clinical randomized controlled trials (RCTs) of ICIs as first-line treatment for NSCLC patients. The search period was from database inception to January 2023. Quality evaluation was conducted using the improved Jadad scale, and meta-analysis was performed using RevMan 5.4 software. ResultsTwelve RCTs were included, all of which were assessed as high-quality literature, involving a total of 7 121 patients. Meta-analysis results showed that, compared with chemotherapy, ICIs as first-line treatment for NSCLC patients significantly improved median overall survival (OS) [HR=0.72, 95%CI (0.64, 0.80), P<0.001] and median progression-free survival (PFS) [HR=0.65, 95%CI (0.53, 0.78), P<0.001], and improved objective response rate (ORR) [RR=1.52, 95%CI (1.28, 1.79), P<0.001]. Subgroup analysis showed that, compared with the ICIs monotherapy group, the ICIs combination therapy group significantly improved OS, PFS, and ORR in NSCLC patients. In terms of safety, the risk of any grade treatment-related adverse events (TRAEs) and grade 3-5 TRAEs in the ICIs group was lower than that in the chemotherapy group. The incidence of TRAEs leading to treatment discontinuation was higher in the ICIs group than in the chemotherapy group. Subgroup analysis showed that the incidence of any grade, grade 3-5, and TRAEs leading to treatment discontinuation was higher in the immune combination therapy group than in the immune monotherapy group. Conclusion ICIs as first-line treatment for NSCLC patients can significantly improve OS, PFS, and ORR compared with chemotherapy. Compared to immune monotherapy, immune combination therapy can significantly improve the efficacy in NSCLC patients, but patients have a higher risk of TRAEs.
Objective To analyze the value of serum microRNAs (miR-218, miR-329, and miR-567) in predicting the clinical efficacy of programmed death-1 (PD-1) inhibitor combined with synchronous chemotherapy in patients with non-small cell lung cancer (NSCLC). Methods A total of 160 patients with NSCLC treated with PD-1 inhibitor combined with synchronous chemotherapy in Taiyuan Hospital, Peking University First Hospital between January 2021 and January 2023 were prospectively selected as the study objects by convenience sampling, and the serum levels of miR-218, miR-329, and miR-567 and the clinical efficacy of the patients were collected. According to the clinical efficacy, the patients were divided into remission group (partial remission and complete remission) and non-remission group (stable disease and disease progression). Receiver operating characteristic (ROC) curve was used to analyze the predictive value of serum miR-218, miR-329 and miR-567 levels in the clinical efficacy of PD-1 inhibitor combined with synchronous chemotherapy in patients with NSCLC. Results Of the 160 patients, 34 (21.2%) had disease progression, 85 (53.1%) had stable disease, 39 (24.4%) had partial remission, and 2 (1.2%) had complete remission. They were divided into remission group (41 cases) and non-remission group (119 cases). Multiple logistic regression analysis showed that high levels of serum miR-218, miR-329, and miR-567 could promote the clinical efficacy of PD-1 inhibitor combined with synchronous chemotherapy in patients with NSCLC (all P<0.05). ROC curve analysis showed that, for predicting the clinical efficacy of PD-1 inhibitor combined with synchronous chemotherapy in patients with NSCLC according to the cut-off value of the joint prediction probability of serum miR-218, miR-329, and miR-567, the area under the ROC curve was 0.938 [95% confidence interval (0.855, 0.964)], and the sensitivity, specificity, positive predictive value, and negative predictive value were 82.9%, 92.4%, 79.1%, and 94.0%, respectively. Conclusion The combined detection of serum miR-218, miR-329 and miR-567 levels has a high predictive value for the therapeutic effect of PD-1 inhibitor combined with synchronous chemotherapy in patients with NSCLC.

ObjectiveTo investigate the effect of multidisciplinary team (MDT) on perioperative complications and clinical efficacy of patients who were receiver radical operation to treat lung cancer by video-assisted thoracoscopic surgery (VATS). MethodsEighty patients in the Thoracic Surgery Department of First Hospital of Lanzhou University from December 2017 to February 2019 who were diagnosed lung cancer were divided into two groups. Forty patients in the MDT group were treated with MDT discussion. The control group consisted of 40 patients who were treated without MDT discussion. The incidence of postoperative complications and clinical efficacy were compared between the two groups . ResultsThere was no statistical difference in incision infection, atelectasis, pleural effusion and pulmonary leakage between the two groups. However, the incidence of postoperative pulmonary infection (5% vs. 20%, P=0.043) and the overall postoperative complications (17.5% vs. 42.5%, P=0.015) in the MDT group was lower than that in the control group with a statistical difference. In the MDT group, the operative time (140.3±8.0 min vs. 148.8±6.8 min, P<0.001), intraoperative bleeding ( 207.8±19.4 mL vs. 222.0±28.3 mL, P=0.010), lymph node dissection number (25.1±6.2 vs. 20.1±7.0, P=0.001), postoperative drainage (273.0±33.5 mL vs. 24.0±52.5 mL, P<0.001), drainage duration (81.9±6.1 h vs. 85.3±8.1 h, P=0.039), pain on the first day after surgery (4.6±0.7 vs. 5.4±0.7), P<0.001), pain on the second day (2.5±0.7 vs. 3.0±0.8, P=0.002), pain on the third day (1.1±0.8 vs. 1.5±0.6, P=0.014), postoperative activity time (40.7±6.7 h vs. 35.3±7.1 h, P<0.001), postoperative recovery time (6.8±0.9 d vs. 7.4±0.7 d, P=0.003), patient satisfaction (8.1±1.4 vs. 7.2±2.0, P=0.020) were significantly better than those of the control group with statistical differences. But there was no statistical difference in the conversion to thoracotomy between the two group. ConclusionMDT discussion can reduce the surgical risk and postoperative complications, improve the clinical efficacy and accelerate the postoperative rehabilitation of patients, which has a good clinical significance.
ObjectiveTo systematically review efficacy of endoscopic ultrasonography guided biliary drainage (EUS-BD) and percutaneous transhepatic biliary drainage (PTBD) on patients with malignant obstructive jaundice.MethodsThe PubMed, EMbase, The Cochrane Library, CBM, WanFang Data, and CNKI were searched online to collect the randomized controlled trials or cohort studies of EUS-BD versus PTBD on the patients with malignant obstructive jaundice from inception to November 30, 2018. Two reviewers independently screened the literatures, extracted the data and assessed the risk of bias of included the studies, then the meta-analysis was performed by using the RevMan 5.3 software.ResultsThree randomized controlled trials and 6 cohort studies involving 496 patients were included. The results of meta-analysis showed that: compared with the PTBD, the EUS-BD had the lower occurrence of complications [OR=0.30, 95% CI (0.20, 0.47), P<0.000 01], lower rate of reintervention [OR=0.11, 95% CI (0.06, 0.22), P<0.000 01], shorter hospital stay [MD=–3.42, 95% CI (–6.72, –0.13), P=0.04], and less hospital costs [SMD=–0.83, 95% CI (–1.16, –0.49), P<0.000 01]. There were no significant differences in the technical success rate [OR=0.88, 95% CI (0.20, 3.85), P=0.86] and clinical effective rate [OR=1.73, 95% CI (0.97, 3.11), P=0.06] between the two groups.ConclusionsCurrent evidence shows that EUS-BD has some advantages of lower occurrence of complications, lower rate of reintervention, shorter hospital stay, and less hospital costs in treatment of patients with malignant obstructive jaundice as compared with PTBD. There are no significant differences between two groups in technical success rate and clinical effective rate. Due to limited quality and quantity of included studies, more high quality studies required to be verified above conclusions.
Objective To compare two kinds of myofascial flap encapsulating adi pose-derived stromal cells (ADSCs) in adi pogenic efficacy in vivo, and to provide experimental basis for the efficient transplantation of free adi pose tissue. Methods ADSCs were isolated from the subcutaneous adipose tissue in the neck of 10 New Zealand rabbits (aged 3-4 months old, male and female, weighing 2.0-2.5 kg), and primary culture and subculture of ADSCs were conducted. When the cells at passage 3 covered 70%-80% of the bottom of the culture flask, BrdU (10 μg/mL) was appl ied to label the cells for 48 hours before performing immunofluorescence staining. Oil red O staining observation was conducted to thosecells 2 weeks after being induced towards adi pocyte, al izarin red staining observation was performed 3 weeks after being induced towards osteoblast, and alcian blue staining was conducted 2 weeks after being induced towards chondrocyte. Besides, after being induced towards adipocyte for 2 weeks, 1 × 107 ADSCs/piece at passage 3 labeled by BrdU was seeded into Col I (10 mm × 10 mm × 5 mm/piece) to prepare cell carrier complex. The experiment was divided into two groups: group A in which vascular pedicled dextral latissimus dorsi fascial flap was adopted to encapsulate the complex; group B in which dextral gluteus maximus fascial flap with no specific vessel pedicle was appl ied to encapsulate the complex. Rabbits in each group went through autogenous ADSCs transplant and self control. The implants were dislodged 8 weeks after operation, HE staining and immunohistochemistry staining were performed to testify cambium, the wet weight and micro vessel count of the cambium in each group were tested, immunofluorescence staining was performed to determine the origin of cambium and microvascular endothel ium. Results The nucleus of ADSCs positive for BrdU label ing showed green fluorescence under fluorescence microscope, with the positive label ing ratio of ADSCs above 90%. For ADSCs at passage 3, the formation of red l ipid droplets within cells was observed 2 weeks after being induced towards adipocyte, red calcium nodules were evident 3 weeks after being induced towards osteoblast, and highly congregated cell mass positive for alcian blue staining appeared 2 weeks after being induced towards chondrocyte. Eight weeks after operation, neogenetic blood vessel grew into scaffolds and no obvious fibreencapsulation was observed in group A, while few blood vessel grew into scaffolds in group B. The wet weight of cambium in group A and B was (0.149 5 ± 0.017 3) g and (0.095 3 ± 0.012 7) g, respectively, indicating there was a significant difference between two groups (P lt; 0.01). HE staining showed the formation of neogenetic adipose tissue and the growth of micrangium in the implant, and the degradation and absorption of scaffold. The micro vessel count of group A and B was 31.2 ± 4.5 and 19.3 ± 2.6, respectively, indicating there was a significant difference between two groups (P lt; 0.01). Eight weeks after operation, the immunofluorescence staining of cambium showed that the cell nucleus of regenerated adi pocytes and partial capillary endothel ium in groups A and B presented green fluorescence. Conclusion ADSCs encapsulated by vascular pedicled latissimus dorsi fascial flap and collagen protein scaffold complex has a higher adi pogenic efficacy in vivo than the gluteus maximus fascial flap with no specific vessel pedicle.
Objective To investigate the influence of self-care and self-efficacy intervention on the quality of life of patients undergoing chemotherapy after surgery for gastric cancer. Methods Sixty-four patients undergoing chemotherapy after gastric cancer surgery between July 2014 and February 2015 were selected as the study subjects. According the sequence of admission, they were divided into intervention group (n=34) and control group (n=30). Patients in the control group accepted conventional care, while those in the intervention group received self-efficacy and self-care interventions. The scores of General Self-efficacy Scale (GCES), Exercise of Self-care Agency (ESCA), and Quality of Life Instruments for Cancer Patients-Stomach Cancer (QLICP-ST) were compared between the two groups before and after intervention. Results After intervention, GCES scores of the intervention group and the control group were respectively (30.08±4.21) and (20.78±4.58) points; the total scores of ESCA were respectively (132.30±14.81) and (92.45±13.23) points; and the total scores of QLICP-ST were respectively (75.96±9.41) and (56.77±10.32) points. All the above differences between the two groups were significant (P<0.05). Conclusion Self-care and self-efficacy intervention can improve self-care ability and self-efficacy, and improve the quality of life of patients undergoing chemotherapy after gastric cancer surgery.
