OBJECTIVE:External fixators and plate internal fixation are commonly used treatments for comminuted distal radius fractures,each with its own advantages and disadvantages in clinical practice. To systematically evaluate the clinical efficacy and safety of external fixator and plate internal fixation in the treatment of comminuted distal radius fractures,and to provide a basis for the development of guidelines for the diagnosis and treatment of distal radius fractures with integrated traditional Chinese and Western medicine. METHODS:PubMed,Web of Science,Embase,Cochrane Library,China National Knowledge Infrastructure,China Biomedical Literature Database,VIP,andWanFang databases were systematically searched to include randomized controlled trials on external fixators and internal plate fixation for the treatment of comminuted distal radial fractures published from October 2013 to October 2023. The literature was screened according to the inclusion and exclusion criteria. Review Manager was used for literature quality evaluation and meta-analysis.RESULTS:(1) Eight articles were included,including 4 in Chinese and 4 in English,with a total sample size of 648 cases,including 328 cases in the external fixation stent group and 320 cases in the internal fixation plate group. (2) At 3 months after operation,the internal fixation plate group was superior to the external fixation stent group in the range of dorsal extension,palmar flexion and supination. At 12 months after operation,the grip strength,palmar inclination,palmar flexion,pronation and supination in the internal fixation plate group were better than those in the external fixation stent group. The postoperative infection in the internal fixation plate group was better than that in the external fixation stent group,and there was no statistical difference in other outcome indicators.CONCLUSION:Eight evidences showed that in the choice of treatment for comminuted distal radius fracture,both external fixation stent and incision plate internal fixation had good therapeutic effect,and plate internal fixation was better than other factors. However,for some special patients with highly severe comminuted distal radius fractures,poor bone quality,severely contaminated open fractures,and soft tissue swelling that did not allow incision surgery,external fixation was the first choice. The results of this study have limitations,and more high-quality,large-sample,multi-center randomized controlled trials are needed in the future,emphasizing the observation of long-term efficacy and other secondary indicators,and supplementing and optimizing the current research results.

Although immunotherapy has made a breakthrough in the treatment of cancer,the emergence of drug resistance has limited be-nefits in most patients,and reversing immunotherapy resistance remains a hotly debated and unresolved issue.The tumor microenviron-ment(TME)comprises a large number of T lymphocytes.During the biological processes of proliferation,activation,and the effect of tumor-infiltrating lymphocytes(TILs),TILs face severe local metabolic stress,resulting in metabolic reprogramming to meet the markedly increased energy demand and biosynthesis requirements.This process of adaptive changes in the metabolic pattern is closely related to the pheno-type and function of TILs,affecting immunotherapy efficacy and mediating immunotherapy resistance.In recent years,with the study of TIL metabolism and the search for specific metabolic regulatory points,targeting the TIL metabolic pathway could restore the tumor-killing func-tion and reverse immunotherapy resistance.This review explores the relationship between the metabolic reprogramming of TILs and im-mune resistance,and provides a new strategy for reversing immune resistance.

Objective To introduce the robotic-assisted left hemicolectomy and Soave procedure and its clinical outcome for Hirschsprung's allied disease.Methods From June 2015 to November 2022,19 cases diagnosed with Hirschsprung's allied disease underwent left colectomy and Soave pull-through by using the da Vinci surgical system,and the clinical data of 19 children were summarized and analyzed.A four trocar technique was used.The left colon was firstly mobilized by laparoscopy from splenic flexure of colon to the level of peritoneal reflection,then the rectum was mobilized by Robotic system to the level of dentate line.A circumferential incision was made in the mucosa at 0.5 cm proximal to the dentate line.The upward submucosal dissection was carried out for approximately 1-2 cm.The left colon was pulled through the anal canal and resected.The coloanal anastomosis was fashioned manually 0.5 cm above the dentate line.21 cases underwent conventional laparoscopic-assisted Soave surgery were used as control group.Results All patients were successfully operated.Compared with conventional laparoscopic-assisted Soave surgery,the operation time was significantly prolonged(P＜0.01),the intraoperative blood loss was significantly reduced(P＜0.01),and the overall postoperative complication rate was significantly reduced(11％VS.43％,P＜0.05).There were no serious complications such as major bleeding and death.Conclusion Robotic-assisted left hemicolectomy and Soave procedure are safe and feasible in the treatment of Hirschsprung's allied disease,with few postoperative complications and satisfactory clinical outcome.

Objective:To compare the differences in the prevalence of mild micro-hepatic encephalopathy (MHE) among patients with cirrhosis by using the psychometric hepatic encephalopathy score (PHES) and the Stroop smartphone application (Encephal App) test.Methods:This prospective, multi-center, real-world study was initiated by the National Clinical Medical Research Center for Infectious Diseases and the Portal Hypertension Alliance and registered with International ClinicalTrials.gov (NCT05140837). 354 cases of cirrhosis were enrolled in 19 hospitals across the country. PHES (including digital connection tests A and B, digital symbol tests, trajectory drawing tests, and serial management tests) and the Stroop test were conducted in all of them. PHES was differentiated using standard diagnostic criteria established by the two studies in China and South Korea. The Stroop test was evaluated based on the criteria of the research and development team. The impact of different diagnostic standards or methods on the incidence of MHE in patients with cirrhosis was analyzed. Data between groups were differentiated using the t-test, Mann-Whitney U test, and χ2 test. A kappa test was used to compare the consistency between groups. Results:After PHES, the prevalence of MHE among 354 cases of cirrhosis was 78.53% and 15.25%, respectively, based on Chinese research standards and Korean research normal value standards. However, the prevalence of MHE was 56.78% based on the Stroop test, and the differences in pairwise comparisons among the three groups were statistically significant (kappa = -0.064, P < 0.001). Stratified analysis revealed that the MHE prevalence in three groups of patients with Child-Pugh classes A, B, and C was 74.14%, 83.33%, and 88.24%, respectively, according to the normal value standards of Chinese researchers, while the MHE prevalence rates in three groups of patients with Child-Pugh classes A, B, and C were 8.29%, 23.53%, and 38.24%, respectively, according to the normal value standards of Korean researchers. Furthermore, the prevalence rates of MHE in the three groups of patients with Child-Pugh grades A, B, and C were 52.68%, 58.82%, and 73.53%, respectively, according to the Stroop test standard. However, among the results of each diagnostic standard, the prevalence of MHE showed an increasing trend with an increasing Child-Pugh grade. Further comparison demonstrated that the scores obtained by the number connection test A and the number symbol test were consistent according to the normal value standards of the two studies in China and South Korea ( Z = -0.982, -1.702; P = 0.326, 0.089), while the other three sub-tests had significant differences ( P < 0.001). Conclusion:The prevalence rate of MHE in the cirrhotic population is high, but the prevalence of MHE obtained by using different diagnostic criteria or methods varies greatly. Therefore, in line with the current changes in demographics and disease spectrum, it is necessary to enroll a larger sample size of a healthy population as a control. Moreover, the establishment of more reliable diagnostic scoring criteria will serve as a basis for obtaining accurate MHE incidence and formulating diagnosis and treatment strategies in cirrhotic populations.

Objective To investigate the impact of pooling of inactivated samples on testing results of nucleic acid detection of SARS-CoV-2, and to provide a scientific detection scheme for the SARS-CoV-2 nucleic acid screening of large population samples. Methods The SARS-CoV-2 positive throat swab samples and the negative throat swab samples were inactivated at 56°C for 30 minutes, and mixed according to the ratio of positive samples to negative samples at 1:4, 1:9, and 1:19, respectively. Real-time fluorescent RT-PCR technology was used to detect the ORF-lab and N genes in the original solution and mixed solution. Results The nucleic acid test results of the 20 groups of inactivated samples were all positive. The nucleic acid test results of the 1:5 mixture and the 1:10 mixture were also positive. One group of samples of the 1:20 mixture was negative for ORF-lab and positive for the N gene. The Ct values of nucleic acid detection among all groups were significantly correlated. There was no statistically significant difference in the positive rate between different sample groups. Compared with the original solution, the Ct values of the ORF-lab gene of 1:5 mixture, 1:10 mixture, and 1:20 mixture samples increased by 1.73, 2.86, and 4.05, respectively, while the Ct values of the N gene of 1:5 mixture, 1:10 mixture and 1:20 mixture samples increased by 1.69, 2.79, and 3.25, respectively. Conclusion When conducting nucleic acid screening for SARS-CoV-2 in large population samples, a mixed test of less than 10 inactivated samples would not affect the qualitative results in most cases, but the results of weak positive samples may be affected.

Objective To understand the status of new coronavirus contamination in the biosafety laboratory environment, identify key areas prone to contamination, and provide evidence for disinfection of central objects. Methods surfaces of high-frequency contact environment and protective equipment were sampled with moistened sterile cotton swabs after experiment and before disinfection, the results of the one-step real-time reverse transcription polymerase chain reaction (RT-PCR) of open reading frame 1ab and N fragment were used to evaluate the pollution status. Results Environmental surveys found 4 of 217 samples of environmental objects to be positive for new coronavirus RNA, that positive rate was 1.84%. Among them, BSL-3, BSL-2, and BSL-1 were sampled 23, 184, and 10 respectively. The 3 positive samples were from surfaces of nucleic acid extraction room of BSL-2 and from the handles of pass-through box, laboratory door handles and the outer surface of the alcohol watering pot respectively. The 1 positive sample was from the forearm of the protective clothing in BSL-2 laboratory. Conclusion There was a certain degree of virus pollution in key areas of the new coronavirus laboratory. The BSL-2 laboratory has a higher risk of environmental pollution than the BSL-3 and BSL-1 laboratories.
