BACKGROUND:At present,osteoarthritis has become a major disease affecting the quality of life of the elderly,and the therapeutic effect is poor,often focusing on preventing the disease process,and the pathogenesis of osteoarthritis is still not fully understood.Bioinformatics analysis was carried out to explore the main pathogenesis of osteoarthritis and related mechanisms of gene coding regulation. OBJECTIVE:To screen core differential genes with a major role in osteoarthritis by gene expression profiling. METHODS:Datasets were downloaded from the Gene Expression Omnibus(GEO):GSE114007,GSE117999,and GSE129147.Differential genes in the GSE114007 and GSE117999 data collections were screened using R software,performing differential genes to weighted gene co-expression network analysis.The module genes most relevant to osteoarthritis were selected to perform protein interaction analysis.Candidate core genes were selected using the cytocape software.The candidate core genes were subsequently subjected to least absolute shrinkage and selection operator regression and COX analysis to identify the core genes with a key role in osteoarthritis.The accuracy of the core genes was validated using an external dataset,GSE129147. RESULTS AND CONCLUSION:(1)A total of 477 differential genes were identified,265 differential genes associated with osteoarthritis were obtained by weighted gene co-expression network analysis,and 8 candidate core genes were identified.The least absolute shrinkage and selection operator regression analysis finally yielded a differential gene ASPM with core value that was externally validated.(2)It is concluded that abnormal gene ASPM expression screened by bioinformatics plays a key central role in osteoarthritis.

Epilepsy affects over 50 million people worldwide. Drug-resistant epilepsy (DRE) accounts for up to a third of these cases, and neuro-inflammation is thought to play a role in such cases. Despite being a long-debated issue in the field of DRE, the mechanisms underlying neuroinflammation have yet to be fully elucidated. The pro-inflammatory microenvironment within the brain tissue of people with DRE has been probed using single-cell multimodal transcriptomics. Evidence suggests that inflammatory cells and pro-inflammatory cytokines in the nervous system can lead to extensive biochemical changes, such as connexin hemichannel excitability and disruption of neurotransmitter homeostasis. The presence of inflammation may give rise to neuronal network abnormalities that suppress endogenous antiepileptic systems. We focus on the role of neuroinflammation and brain network anomalies in DRE from multiple perspectives to identify critical points for clinical application. We hope to provide an insightful overview to advance the quest for better DRE treatments.

ObjectiveTo evaluate the effectiveness and safety of Qiaoqi Formula （翘芪组方） for mild influenza. MethodsA randomized controlled study was designed， recruiting 74 patients with mild influenza， who were randomly divided into trial group and control group. The trial group took Qiaoqi Formula orally， 40ml each time， twice a day； the control group took Lianhua Qingwen Capsules （连花清瘟胶囊） orally， 1.4 g each time， three times a day. Both groups were treated for 3 consecutive days and follow-up for 4 consecutive days after treatment. The time for fever reduction including onset of fever reduction， complete fever reduction time， fever reduction rates at 24， 48 and 72 hours， improvement of influenza symptoms， total traditional Chinese medicine （TCM） symptom score， and safety indicators in two groups after treatment were recorded. ResultsSixty-five patients were ultimately included， including 36 in the trial group and 29 in the control group. Onset time of fever reduction in the trial group was （15.49±23.47） h， the complete fever reduction time （21.37±30.06）h， and the 24 h， 48 h， 72 h， fever reduction rate was 77.14%， 88.57%， 91.42% respectively. The above indicators of the control group showed as （17.58±20.38）h， （24.30±21.87）h， 61.29%， 90.32%， 96.77% respectively， with no statistically significant differences （P＞0.05）. On the 7th day after treatment， the total score of TCM syndromes in trial group and control group decreased compared to those before treatment （P＜0.05）. There was no statistically significant difference in the cure rate， significant effective rate， effective rate， and total effective rate of TCM syndromes between groups （P＞0.05）. On the 4th day， the lymphocyte ratio of patients in the control group was higher than before treatment， while alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， urea， and creatinine of both groups before and after treatment were within the normal range. The main adverse reactions in both groups were mild headache and dizziness， and no serious adverse reactions observed. ConclusionThe therapeutic effect of Qiaoqi Formula in treating mild influenza is equivalent to Lianhua Qingwen Capsules， which can shorten the fever reduction time， improve clinical symptoms， and no adverse events observed during the study.

Objective To construct a model of heart failure risk prediction based on four machine learning algo-rithms in order to support early diagnosis and intervention.Methods After reviewing the heart failure dataset pub-lished on the Kaggle community,feature selection was used to select relevant factors related to heart failure as pre-dictive indicators.Four machine learning algorithms,namely logistic regression,support vector machine,random forest,and XGBoost were selected to establish predictive models.Compared and analyzed its accuracy,precision,recall,F1 score and area under the ROC curve(AUC)to verify the performance of the model.Results The study analyzed 11 features of 918 patients with heart failure and selected 10 feature factors for modeling.After optimizing the hyper-parameters through grid search,the XGBoost model performed the best,with accuracy,precision,recall,and f1_score and AUC values were 87.5%,90.38%,89.71%,90.04%and 0.93,respectively.In addition,data analysis showed that exercise ST slope,chest pain type,and exercise induced angina were main influencing factors for heart failure.Conclusions The XG Boost model has the best predictive tool for heart failure,and machine learning algorithms may support early prevention,early diagnosis as well as control of heart failure.

Objective:To explore the disease spectrum and corresponding clinical indicators of infantile cholestasis so as to provide a basis for the diagnosis of this type of disease at an early stage.Methods:The clinical data was collected from 203 hospitalized children diagnosed with infantile cholestasis at the Department of Gastroenterology of Maternal and Child Health Care, Guiyang City, from January 2018 to March 2023, including 130 males and 73 females. Patients general condition, personal history, and blood biochemical test indicators, including liver and coagulation function, blood ammonia, blood lipid profile, blood sugar, TORCH, thyroid function, and others, were retrospectively analyzed after admission. Cholangiography and high-throughput gene sequencing were performed in certain patients. The etiology of the enrolled cases were analyzed. Children's clinical data were compared with distinct inherited metabolic liver diseases (Group A) and biliary atresia (Group B). The statistical analysis was conducted using the t-test, Mann-Whitney test, Kruskal-Wallis test, or χ2 test, according to different data. Results:In 33 cases, infectious factors—primarily CMV infection—were the etiology of cholestasis. Forty cases had aberrant bile duct development, primarily biliary atresia, choledochal cysts, and intrahepatic bile duct dysplasia. In 26 cases, genetic metabolic factors mainly included citrin protein deficiency, sodium-taurocholate co-transporting polypeptide deficiency, and Alagille syndrome. 11 cases had drug/poisoning factors (parenteral nutrition-associated cholestasis). 19 cases had idiopathic infantile cholestasis. Three cases had other factors; however, all of them had Kawasaki disease. 71 cases had an unclear diagnosis. There was no statistically significant difference in terms of gender and age between groups A and B ( P>0.05). The alkaline phosphatase (ALP) and bile acid levels were significantly higher in Group A than Group B, with a P<0.05, while the gamma glutamyltransferase (GGT), direct bilirubin (DBil), and albumin levels were lower than those in Group B, with a P<0.05. The cytomegalovirus infection rate was higher in Group B (62.50%) than Group A (34.62%), and the difference between the two groups was statistically significant ( χ2=3.89, P<0.05). The alanine aminotransferase, aspartate aminotransferase, GGT, DBil, and albumin were significantly lower in patients with citrin protein deficiency than those in patients with biliary atresia, while ALP, bile acid, and blood ammonia were higher than those in patients with biliary atresia. Patients with sodium-taurocholate co-transporting polypeptide deficiency had higher bile acid than patients with biliary atresia, while the DBil was lower than that in patients with biliary atresia, and the difference was statistically significant ( P<0.05). Conclusion:Infantile cholestasis etiology is diverse. ALP, bile acids, GGT, DBil, and albumin levels can serve as simple indicators for early-stage differentiation between inherited metabolic liver disease and biliary atresia. The cholestasis etiology should be determined as early as possible following biliary atresia exclusion by actively completing genetic metabolic gene detection.

Objective To investigate the relationship between Kirsten rat sarcoma viral oncogene homolog(KRAS),neuroblastoma viral oncogene RAS homolog(NRAS),V-raf murine sarcoma viral oncogene homo-log B(BRAF),human epidermal growth factor receptor 2(HER2)gene mutations and microsatellite instabili-ty(MSI)status and clinicopathological features in patients with colorectal cancer.Methods The clinical data of 226 patients with colorectal cancer treated in the hospital from October 2019 to March 2022 were collected.Next-generation sequencing technology was used to detect KRAS,NRAS,BRAF,HER2 gene mutations and MSI status.Immunohistochemistry was used to evaluate the mismatch repair system(MMR)status.Multiva-riate Logistic regression analysis was used to analyze the relationship between KRAS,NRAS,BRAF,HER2 gene mutations and clinicopathological features.Results Among 226 colorectal cancer patients,the mutation frequencies of KRAS,NRAS,BRAF and HER2 were 54.89％,5.3％,8.4％and 1.8％,respectively.The fre-quency of KRAS mutation in mucinous adenocarcinoma was higher than that in common adenocarcinoma(P＜0.05).The risk of KRAS mutation in right colon cancer was increased(OR=2.145,P=0.012).NR AS gene mutation was more frequent in left colon and rectal cancer(P＜0.05).The frequency of BRAF gene mu-tation was higher in poorly differentiated and microsatellite instability-high(MSI-H)colorectal cancer(P＜0.05),and the risk of BRAF gene mutation in the right colon was increased(OR=2.844,P=0.042).HER2 gene amplification mutation showed distant metastasis(P＜0.05).KRAS mutations were mutually exclusive with NRAS,BRAF and HER2 amplification mutations(P＜0.05).MSI-H was more frequent in the right co-lon(P＜0.05).Of the 226 cases,10 cases were defective mismatch repair(dMMR)/MSI-H,8 cases were dM-MR/microsatellite stable,and 5 cases were proficient mismatch repair/MSI-H.There was a moderate agree-ment between dMMR and MSI-H(Kappa=0.575).Conclusion KRAS,NRAS,BRAF,HER2 and MSI sta-tus are associated with clinicopathological features in patients with colorectal cancer.Combined detection of KRAS,NRAS,BRAF,HER2 and MSI can provide more accurate and effective data to guide the treatment and prognosis of patients.

Objective:To investigate the clinical efficacy of arthroscopic modified anatomic glenoid reconstruction with Enden-Hybinette procedure combined with loop plate fixation in the treatment of recurrent anterior dislocation of shoulder combined with severe glenoid bone loss.Methods:A retrospective case series study was conducted to analyze 36 patients with recurrent anterior dislocation of the shoulder combined with severe glenoid bone loss who were admitted to 901st Hospital of the Joint Logistics Support Force of PLA from January 2019 to January 2021, including 28 males and 8 females, aged 18-33 years [(29.5±3.0)years]. All the patients had injury history. The dislocation frequency range was 2-40 times [(20.5±6.5)times]. Beighton scale scores were 3-9 points [(4.0±0.8)points]. All the patients underwent anatomic reconstruction of the glenoid bone with arthroscopic modified Enden-Hybinette procedure using iliac autograft and loop plate elastic fixation. Posterior glenoid version angle, the breadth of the glenoid cavity and the A-P glenoid cavity depth were measured and osseous anatomy of the reconstructed glenoid bone was evaluated. Union of the Iliac bone block and glenoid bone loss was observed and the absorption rate of the bone block was evaluated at 6 months after surgery. The shoulder stability score, functional activity score, joint range of motion score and total Rowe score of shoulder function were used to evaluate the shoulder stability, functional activity and movement before surgery, at 3, 6 months after surgery and at the last follow-up. The incidence of complications was observed.Results:All the patients were followed up for 12-24 months [(18.8±3.5)months]. At 1, 3, 6 months after surgery and at the last follow-up, posterior glenoid version angle was (11.3±1.7)°, (10.6±1.2)°, (9.1±2.0)° and (9.2±1.9)° respectively; the breadth of the glenoid cavity was (34.2±1.3)mm, (33.2±1.0)mm, (32.2±1.0)mm and (31.3±1.1)mm respectively; the A-P glenoid cavity depth was (2.6±0.1)mm, (2.4±0.1)mm, (2.3±0.2)mm and (2.2±0.2)mm respectively, which were all significantly improved compared with those before surgery [(-5.9±1.0)°, (24.3±1.2)mm and (0.6±0.1)mm respectively] ( P<0.01), with no significant differences among those at different postoperative time points ( P>0.05). Bony union was observed in the iliac bone block and glenoid bone loss after bone grafting in all the patients at 6 months after surgery and the iliac bone block resorption rate was (20.5±4.1)%. At 3, 6 months after surgery and at the last follow-up, the shoulder stability score was (41.5±6.1)points, (43.9±6.3)points and (44.7±5.0)points respectively; the functional activity score was (26.9±2.5)points, (27.1±2.5)points and (28.6±2.3)points respectively; the joint range of motion score was (13.9±1.0)points, (14.9±1.2)points and (15.8±1.5)points respectively; the total Rowe score of shoulder function was (81.4±11.5)points, (85.8±12.3)points and (86.4±9.8)points respectively, which were significantly improved compared with those before surgery [(6.1±1.5)points, (11.9±1.5)points, (8.5±1.4)points and (27.4±7.5)points respectively] ( P<0.01), with no significant differences among those at different postoperative time points ( P>0.05). At the follow-up, no complications such as incision infection, neurological injuries, implant failure of displacement, recurrent re-dislocation of the shoulder or osteoarthritis were observed.

Objective:To evaluate the safety of double and a half layered esophagojejunal anastomosis in radical gastrectomy.Methods:This prospective, multi-center, single-arm study was initiated by the Affiliated Cancer Hospital of Zhengzhou University in June 2021 (CRAFT Study, NCT05282563). Participating institutions included Nanyang Central Hospital, Zhumadian Central Hospital, Luoyang Central Hospital, First Affiliated Hospital of Henan Polytechnic University, First Affiliated Hospital of Henan University, Luohe Central Hospital, the People's Hospital of Hebi, First People's Hospital of Shangqiu, Anyang Tumor Hospital, First People's Hospital of Pingdingshan, and Zhengzhou Central Hospital Affiliated to Zhengzhou University. Inclusion criteria were as follows: (1) gastric adenocarcinoma confirmed by preoperative gastroscopy;(2) preoperative imaging assessment indicated that R0 resection was feasible; (3) preoperative assessment showed no contraindications to surgery;(4) esophagojejunostomy planned during the procedure; (5) patients volunteered to participate in this study and gave their written informed consent; (6) ECOG score 0–1; and (7) ASA score I–III. Exclusion criteria were as follows: (1) history of upper abdominal surgery (except laparoscopic cholecystectomy);(2) history of gastric surgery (except endoscopic submucosal dissection and endoscopic mucosal resection); (3) pregnancy or lactation;(4) emergency surgery for gastric cancer-related complications (perforation, hemorrhage, obstruction); (5) other malignant tumors within 5 years or coexisting malignant tumors;(6) arterial embolism within 6 months, such as angina pectoris, myocardial infarction, and cerebrovascular accident; and (7) comorbidities or mental health abnormalities that could affect patients' participation in the study. Patients were eliminated from the study if: (1) radical gastrectomy could not be completed; (2) end-to-side esophagojejunal anastomosis was not performed during the procedure; or (3) esophagojejunal anastomosis reinforcement was not possible. Double and a half layered esophagojejunal anastomosis was performed as follows: (1) Open surgery: the full thickness of the anastomosis is continuously sutured, followed by embedding the seromuscular layer with barbed or 3-0 absorbable sutures. The anastomosis is sutured with an average of six to eight stitches. (2) Laparoscopic surgery: the anastomosis is strengthened by counterclockwise full-layer sutures. Once the anastomosis has been sutured to the right posterior aspect of the anastomosis, the jejunum stump is pulled to the right and the anastomosis turned over to continue to complete reinforcement of the posterior wall. The suture interval is approximately 5 mm. After completing the full-thickness suture, the anastomosis is embedded in the seromuscular layer. Relevant data of patients who had undergone radical gastrectomy in the above 12 centers from June 2021 were collected and analyzed. The primary outcome was safety (e.g., postoperative complications, and treatment). Other studied variables included details of surgery (e.g., surgery time, intraoperative bleeding), postoperative recovery (postoperative time to passing flatus and oral intake, length of hospital stay), and follow-up conditions (quality of life as assessed by Visick scores).Result:[1] From June 2021 to September 2022,457 patients were enrolled, including 355 men and 102 women of median age 60.8±10.1 years and BMI 23.7±3.2 kg/m2. The tumors were located in the upper stomach in 294 patients, mid stomach in 139; and lower stomach in 24. The surgical procedures comprised 48 proximal gastrectomies and 409 total gastrectomies. Neoadjuvant chemotherapy was administered to 85 patients. Other organs were resected in 85 patients. The maximum tumor diameter was 4.3±2.2 cm, number of excised lymph nodes 28.3±15.2, and number of positive lymph nodes five (range one to four. As to pathological stage,83 patients had Stage I disease, 128 Stage II, 237 Stage III, and nine Stage IV. [2] The studied surgery-related variables were as follows: The operation was successfully completed in all patients, 352 via a transabdominal approach, 25 via a transhiatus approach, and 80 via a transthoracoabdominal approach. The whole procedure was performed laparoscopically in 53 patients (11.6%), 189 (41.4%) underwent laparoscopic-assisted surgery, and 215 (47.0%) underwent open surgery. The median intraoperative blood loss was 200 (range, 10–1 350) mL, and the operating time 215.6±66.7 minutes. The anastomotic reinforcement time was 2 (7.3±3.9) minutes for laparoscopic-assisted surgery, 17.6±1.7 minutes for total laparoscopy, and 6.0±1.2 minutes for open surgery. [3] The studied postoperative variables were as follows: The median time to postoperative passage of flatus was 3.1±1.1 days and the postoperative gastrointestinal angiography time 6 (range, 4–13) days. The median time to postoperative oral intake was 7 (range, 2–14) days, and the postoperative hospitalization time 15.8±6.7 days. [4] The safety-related variables were as follows: In total, there were 184 (40.3%) postoperative complications. These comprised esophagojejunal anastomosis complications in 10 patients (2.2%), four (0.9%) being anastomotic leakage (including two cases of subclinical leakage and two of clinical leakage; all resolved with conservative treatment); and six patients (1.3%) with anastomotic stenosis (two who underwent endoscopic balloon dilation 21 and 46 days after surgery, the others improved after a change in diet). There was no anastomotic bleeding. Non-anastomotic complications occurred in 174 patients (38.1%). All patients attended for follow-up at least once, the median follow-up time being 10 (3–18) months. Visick grades were as follows: Class I, 89.1% (407/457); Class II, 7.9% (36/457); Class III, 2.6% (12/457); and Class IV 0.4% (2/457).Conclusion:Double and a half layered esophagojejunal anastomosis in radical gastrectomy is safe and feasible.
