Objective To systematically evaluate the efficacy and safety of video-assisted thoracoscopic surgery (VATS) with different numbers of ports in the treatment of spontaneous pneumothorax. Methods We conducted a comprehensive search of CNKI, PubMed, The Cochrane Library, Web of Science, EMbase, Wanfang Data, and the Chinese Medical Journal Full-text Database for clinical controlled trials on VATS with different port numbers for spontaneous pneumothorax, from their inception to March 2023. Two researchers independently screened the literature and assessed its quality.The Newcastle-Ottawa Scale (NOS) was used to assess the methodological quality of cohort and case-control studies, and the Cochrane risk-of-bias tool was used to evaluate randomized controlled trials (RCT). Meta-analysis was performed using RevMan 5.4.1 software. Results A total of 107 studies were included, comprising 35 RCT, 2 cohort studies, and 70 case-control studies. All cohort and case-control studies included in the analysis had NOS scores≥7. The meta-analysis revealed that compared to two-port VATS (2P-VATS) and three-port VATS (3P-VATS), single-port thoracoscopic surgery (SPTS) was associated with less intraoperative blood loss (SMD=–1.58, 95%CI: –1.93 to –1.22, P<0.001; and SMD=–1.59, 95%CI: –2.03 to –1.14, P<0.001, respectively), shorter postoperative hospital stay (SMD=–1.05, 95%CI: –1.29 to –0.82, P<0.001; and SMD=–1.08, 95%CI: –1.39 to –0.77, P<0.001), shorter duration of postoperative chest tube drainage (SMD=–0.75, 95%CI: –1.00 to –0.50, P<0.001; and SMD=–1.23, 95%CI: –1.72 to –0.75, P<0.001), fewer postoperative complications (OR=0.34, 95%CI: 0.26 to 0.45, P<0.001; and OR=0.47, 95%CI: 0.33 to 0.68, P<0.001), and lower pain scores at 24, 48, and 72 hours after surgery (P<0.05). The operative time for SPTS was shorter than that for 2P-VATS (SMD=–0.53, 95%CI: –0.90 to –0.16, P=0.005) but showed no significant difference compared to 3P-VATS (P=0.21). When comparing 2P-VATS with 3P-VATS, 2P-VATS demonstrated less intraoperative blood loss (SMD=–1.02, 95%CI: –1.81 to –0.22, P=0.01), shorter postoperative hospital stay (SMD=–0.59, 95%CI: –1.11 to –0.06, P=0.03), shorter duration of chest tube drainage (SMD=–0.46, 95%CI: –0.85 to –0.08, P=0.02), fewer postoperative complications (OR=0.36, 95%CI: 0.22 to 0.59, P<0.001), and lower pain scores at 24, 48, and 72 hours after surgery (P≤0.05). Conclusion Both SPTS and 2P-VATS are effective and safe surgical options for spontaneous pneumothorax, deserving further promotion and application in clinical practice. However, due to limitations in the quantity and quality of the included studies, more large-sample, high-quality research is needed to validate these findings.

Objective To systematically evaluate the efficacy of immune checkpoint inhibitors (ICIs) in treating esophageal cancer patients of different genders. Methods Computer searches were conducted on PubMed, Cochrane Library, and Embase databases to collect randomized controlled trial (RCT) on ICIs treatment for esophageal cancer patients from the establishment of the databases to January 25, 2024. Two researchers independently screened the literature and extracted data according to the inclusion and exclusion criteria. The outcome indicators were overall survival (OS) and progression-free survival (PFS), and RevMan 5.4 software was used for meta-analysis. The modified Jadad scoring scale was used to evaluate the quality of the included literature. Results A total of 10 RCT involving 5364 esophageal cancer patients were included in this study, with 2684 patients in the trial group and 2680 patients in the control group. The Jadad scores of the included literature were all ≥6 points, indicating high-quality RCT. Meta-analysis results showed that female esophageal cancer patients receiving ICIs treatment [HR=0.72, 95%CI (0.59, 0.87), P<0.001] had a more significant median OS prolongation than male patients [HR=0.73, 95%CI (0.68, 0.78), P<0.001]; while male patients [HR=0.57, 95%CI (0.52, 0.64), P<0.001] had a more significant PFS prolongation than female patients [HR=0.72, 95%CI (0.55, 0.94), P=0.01]. Female patients treated with ICIs alone [HR=0.66, 95%CI (0.50, 0.87), P=0.003] had a more significant median OS prolongation than male patients [HR=0.79, 95%CI (0.72, 0.87), P<0.001]; while male patients receiving ICIs combined with chemotherapy [HR=0.67, 95%CI (0.61, 0.74), P<0.001] had a more significant median OS prolongation than female patients [HR=0.77, 95%CI (0.59, 1.01), P=0.06]. Conclusion Female patients receiving ICIs have a slight advantage in OS compared to male patients, while male patients have an advantage in PFS. Male patients receiving ICIs combined with chemotherapy have better survival benefits than female patients, while female patients using ICIs monotherapy have better survival benefits than male patients.

Objective To systematically evaluate the therapeutic effects of video-assisted thoracoscopic surgery (VATS) and robot-assisted thoracic surgery (RATS) in treating mediastinal tumors. Methods A computer search was conducted on PubMed, Embase, Cochrane Library, Web of Science, Wanfang, CNKI, CBM, VIP databases for literature comparing the clinical efficacy of VATS and RATS in treating mediastinal tumors, with the search time from inception to March 31, 2024. The Newcastle-Ottawa Scale (NOS) was used to evaluate the quality of the included cohort studies, and Review Manager 5.4 software was used to perform a meta-analysis. Results A total of 32 articles were included, with 7868 patients. The NOS scores of the included cohort studies were all≥7 points. Meta-analysis results showed that compared with the VATS group, the RATS group had less intraoperative blood loss [MD=−16.71, 95%CI (−23.88, −9.54), P<0.001], lower conversion rate to open thoracotomy [OR=0.41, 95%CI (0.26, 0.67), P=0.003], lower overall postoperative complication rate [OR=0.66, 95%CI (0.48, 0.92), P=0.01], shorter postoperative drainage time [MD=−0.64, 95%CI (−0.92, −0.36), P<0.001], and shorter postoperative hospital stay [MD=−1.03, 95%CI (−1.28, −0.78), P<0.001]. There was no statistical difference between the two groups in terms of tumor size [MD=−0.06, 95%CI (−0.31, 0.19), P=0.64] or operation time [MD=5.52, 95%CI (−2.35, 13.40), P=0.17]. The RATS group had higher hospitalization costs than the VATS group [MD=1.69, 95%CI (1.26, 2.13), P<0.001]. Conclusion In mediastinal tumors resection, RATS is superior to VATS in terms of intraoperative blood loss, conversion rate to open thoracotomy, overall postoperative complication rate, postoperative drainage time, and postoperative hospital stay, but it increases hospitalization costs.

Objective To systematically evaluate the efficacy and safety of single-port thoracoscopic surgery (SPTS) in the treatment of spontaneous pneumothorax. Methods Computer searches were conducted in PubMed, The Cochrane Library, Web of Science, Embase, CNKI, WanFang, and the Chinese Medical Association databases to collect randomized controlled trials (RCTs) and cohort studies on the comparison of efficacy and safety of SPTS and three-port thoracoscopic surgery (TPTS) for the treatment of spontaneous pneumothorax from their inception to March 2024. The Cochrane RCT bias risk assessment tool and the Newcastle-Ottawa Scale (NOS) were used to assess the quality of RCTs and cohort studies, respectively. Meta-analysis was performed using RevMan 5.4.1. Results A total of 68 studies were included, comprising 23 RCTs and 45 cohort studies with a total of 5403 patients. The NOS scores of the cohort studies were 7-8 points. Meta-analysis results showed that compared with TPTS, SPTS had less intraoperative blood loss [SMD=−1.58, 95%CI (−1.93, −1.22), P<0.001], shorter postoperative hospital stay [SMD=−1.05, 95%CI (−1.29, −0.82), P<0.001], shorter postoperative drainage tube placement time [SMD=−0.75, 95%CI (−1.00, −0.50), P<0.001], fewer postoperative complications [OR=0.34, 95%CI (0.26, 0.45), P<0.001], fewer postoperative recurrences [OR=0.48, 95%CI (0.32, 0.72), P<0.001], and less pain at 24, 48, and 72 h postoperatively [SMD=−1.71, 95%CI (−2.13, −1.30), P<0.001; SMD=−1.70, 95%CI (−2.35, −1.06), P<0.001; SMD=−1.72, 95%CI (−2.16, −1.29), P<0.001]. Conclusion SPTS is safe and effective in the treatment of spontaneous pneumothorax with high clinical value and can be further promoted in clinical practice. Considering the limitations in the number and quality of included studies, researches with larger sample sizes and higher quality are needed to validate the above conclusions.

Objective To evaluate the efficacy and safety of concurrent chemoradiotherapy versus sequential chemoradiotherapy in the treatment of locally advanced non-small cell lung cancer. Methods The relevant literature was searched in PubMed, Web of Science, CNKI and Wanfang databases from the inception to October 15, 2023, and the literature was screened according to the inclusion and exclusion criteria. Review Manager 5.3 software was used for meta-analysis of the literature, and the Cochrane bias risk assessment tool was used to evaluate the quality of the literature. Results Finally, 14 randomized controlled studies were included covering a total of 1048 patients. The results of meta-analysis showed that the overall response rate [OR=2.39, 95%CI (1.83, 3.11)], 1-year survival rate [OR=1.81, 95%CI (1.39, 2.35)], 2-year survival rate [OR=1.75, 95%CI (1.27, 2.42)] and 3-year survival rate [OR=2.33, 95%CI (1.49, 3.66)] were superior to sequential chemoradiotherapy (P<0.001). In terms of safety, concurrent chemoradiotherapy increased the incidence of radiation esophagitis (P<0.05), but there was no statistical difference in the incidence of leukopenia and radiation pneumonia (P>0.05). Conclusion For patients with locally advanced non-small cell lung cancer, the short-term efficacy of concurrent chemoradiotherapy is better than that of sequential chemoradiotherapy and can improve the 1-, 2- and 3-year survival rates, but the toxic side effects of the treatment are slightly greater than those of the sequential chemoradiotherapy.

Spine fracture and dislocation are common traumatic spinal conditions that often require surgical intervention due to compromised spinal stability. Surgical approaches include anterior, posterior, and combined anterior-posterior spinal procedures. According to the specific surgical requirements, patients may be placed in the prone position or repositioned between prone and supine positions during surgery. Intraoperative repositioning has become an essential step in patient positioning. However, during repositioning, patients with spinal fracture and dislocation are at increased risk for complications such as hemodynamic instability, nerve injury, and pressure injuries to the skin and soft tissue. Notably, due to the instability of the spinal cord, even minor manipulations can further exacerbate the damage, potentially leading to severe outcomes like paraplegia. Although the current clinical guidelines provide instructive recommendations for standard position, there remains no specific protocols for intraoperative repositioning in patients with spine fracture and dislocation. With a concern for the lack of clinical studies on positioning techniques, risk prevention, and operational norms for special patients, no applicable guidelines or standards are available. A consensus was required to provide clinical reference, meet the requirements of surgical treatment, and minimize the safety risks of patients caused by improper placement of positions. Professional Committee of Operating Room Nursing of Shaanxi Nursing Association organized experts in nursing management and operating room nursing from major hospitals across China to formulate Expert consensus on intraoperative repositioning for patients with spinal fracture and dislocation ( version 2025). The consensus provides 11 recommendations covering pre-repositioning preparation, intraoperative maneuvers, and post-repositioning observation, aiming to provide references for clinical standardization of the intraoperative repositioning process and protection of patients′ safety.

Objective:This multicenter retrospective study aimed to analyze the clinicopathological features of duodenal adenocarcinoma (DA) and identify prognostic factors for postoperative survival.Methods:Demographic characteristics, clinicopathological features, treatment outcomes and survival of DA patients undergoing surgical treatment at 18 Chinese medical centers from January 2012 to December 2023 were retrospectively analyzed.Results:Among the 2 056 DA patients included, 46.8% (963) had extra-ampullary DA (EA-DA), and 53.2% (1 093) had peri-ampullary DA (PA-DA). The 1-, 3-, and 5-year overall survival (OS) rates for patients who underwent radical surgery were 93.2%, 71.0%, and 57.2%, respectively. The median overall survival was 76 months, and the median progression-free survival (PFS) was 65 months. No differences in survival were observed between the laparotomy group and minimally invasive surgery (MIS) group either before or after propensity score matching (OS: 76 vs. 75 months before PSM, P=0.986; OS: 75 vs. 75 months after PSM, P=0.602). Furthermore, there were no significant differences between-group in operation time and postoperative complications ( P＞0.05). The MIS group experienced less intraoperative blood loss and shorter hospital stays. The multivariate Cox regression analysis revealed that advanced age ( HR=1.43,95% CI:1.18-1.73), elevated carbohydrate antigen 19-9 levels ( HR=1.24,95% CI:1.02-1.51), perineural invasion ( HR=1.44,95% CI:1.14-1.81), vascular invasion ( HR=1.35,95% CI:1.07-1.71), advanced T stage (T3-4 vs. T1-2: HR=1.86,95% CI:1.49-2.31), regional lymph node metastasis ( HR=1.93,95% CI:1.58-2.36), preoperative biliary drainage ( HR=1.26,95% CI:1.04-1.53), intraoperative blood loss ( HR=1.34,95% CI:1.11-1.62), clinically significant postoperative pancreatic fistulas ( HR=1.53,95% CI:1.12-2.09), and postoperative hemorrhage ( HR=1.62,95% CI:1.14-2.29) were independent risk factors for poor prognosis after surgery (all P＜0.05). Conclusions:Radical surgery is associated with favorable overall survival among DA patients, and no difference in survival is observed between EA-DA and PA-DA patients. MIS is a reliable alternative for DA treatment.

Objective:To develop a network-structured clinical pathway grouping rule based on the principles and methods of China healthcare security diagnosis related groups(CHS-DRG), for references for optimizing clinical pathway management.Methods:From August to November 2024, this study constructed a network-structured clinical pathway management framework, followed the grouping principles of CHS-DRG, and developed a network-structured clinical pathway grouping rule through literature analysis and expert discussions. 54 clinical specialists from the sample hospital were organized and grouped according to the rule for the normal magnification cases(139 218 cases) of DRG medical insurance settlement in the hospital in 2023. Using a stratified random sampling method, 205 physicians from 54 clinical specialties in the hospital were selected to quantitatively evaluate the rationality, homogeneity, and clarity of the grouping results. The Likert 5-level scoring method was wsed to assign scores.Results:The network-structured clinical pathway grouping rule and nomenclature was established. A total of 341 main pathways and 35 sub-pathways covering 169 adjacent diagnosis related groups were formed. The quantitative assessment scores for rationality, homogeneity, and clarity were 4.90, 4.87 and 4.87 points, respectively.Conclusions:The network-structured clinical pathway grouping rule based on CHS-DRG had good, feasibility and standardization, and could meet the practical needs of clinical applications.

OBJECTIVE To investigate the result of human immunodeficiency virus(HIV)screening for the people visiting to a three-A hospital of Sichuan Province and analyze the prevalence of complications with hepatitis B virus(HBV)infection,hepatitis C virus(HCV)infection and Treponema pallidum(TP)infection in the emerging HIV infection patients.METHODS The result of HIV screening for the people who visited to Ziyang Central Hos-pital from Jan.1,2020 to Dec.31,2024 and the test results of HBV,HCV and TP for the emerging HIV infec-tion patients were collected and were summarized and statistically analyzed by SPSS.0 software.RESULTS Totally 289 891 case-times were tested for HIV,1529 cases were previously diagnosed with HIV,465 of whom were tested posi-tive for the first time,there was significant difference in the positive rate of test for the first time among the 5 years(x2=15.998,P=0.003).Totally 353 cases were confirmed positive among the 465 primary positive screening cases.Among the emerging HIV infection patients,the positive rate was higher in the male than in the female(x2=141.141,P＜0.001),and the positive rate was high among the population aged more than 40 year old(x2=11.448,P＜0.001),mi-grant workers(x2=270.110,P＜0.001)and low education level population(x2=25.911,P＜0.001).The detection rate of gp41 was up to 100.00％in strip type testing.The analysis of the ratio of relative light unit(RLU)to Cutoff val-ue(COI)in the initial screening experiment showed that when COI was greater than 50,all of the confirmed tests were positive,when COI ranged between 1 and 5,the false positive rate was 97.06％.The incidence of complica-tion with HBV infection in the emerging HIV infection patients was increased year by year(x2=20.355,P＜0.001),and the incidence of complication with HCV infection was increased in recent two years(x2=10.690,P=0.030).CONCLUSIONS There is no obvious rise of positive rate of HIV screening among the people visiting to the hospital in recent 5 years.The sensitivity of the primary screening of clinical laboratory is high without posi-tive missing test.The positive rates of HBV and HCV are increased among the emerging HIV infection patients.
