OBJECTIVE To evaluate the efficacy and safety of Weiyan Tongluo Granules in treating chronic atrophic gastritis(CAG)and explore its potential mechanisms.METHODS From June 2020 to December 2022,100 CAG patients with spleen defi-ciency and blood stasis syndrome were enrolled and randomly divided into a trial group(n=50)and a control group(n=50)using a random number table.The trial group received Weiyan Tongluo Granules plus a folic acid placebo,while the control group received fo-lic acid tablets plus a traditional Chinese medicine granule placebo.The treatment course for both groups was 24 weeks,with 8 and 10 dropouts in the trial and control groups,respectively.Post-treatment comparisons included OLGA/OLGIM staging reversal rates,low-grade intraepithelial neoplasia regression rate,SSDPRO-CG(Patient-Reported Outcome Scale for Chronic Gastritis in Spleen-Stomach Diseases)scores,TCM syndrome scores,and safety indicators.Serum levels of PG I,PGⅡ,PGR,and G-17 were measured via ELISA before and after treatment.Gastric mucosal p-NF-κB and CDX2 protein expression levels were analyzed by Western blot,while mRNA levels of IL-1β,IL-6,VIL1,and MUC2 were quantified via qPCR.RESULTS After treatment,the trial group showed sig-nificantly higher OLGA and OLGIM stage reversal rates than the control group(P<0.05,P<0.01),though no significant difference was observed in low-grade intraepithelial neoplasia regression.Both groups exhibited significant improvements in physiological domain scores and total SSDPRO-CG scores(P<0.01),with the trial group outperforming the control group in physiological,independence,psychological domains,and total scores(P<0.05,P<0.01).TCM syndrome scores(total and sub-items:gastric distension,pain,poor appetite,bloating)decreased significantly in both groups(P<0.01),while the trial group showed greater reductions in loose stools and dull complexion(P<0.01).After-treatment,the trial group had significantly lower TCM syndrome scores than the control group(P<0.05,P<0.01).Serum PG I,PGⅡ,PGR,G-17,gastric mucosal p-NF-κB,CDX2,and IL-1β,IL-6,VIL1,MUC2 mRNA levels improved significantly in the trial group(P<0.05,P<0.01),while the control group improved only in PGⅡ(P<0.05,P<0.01).The trial group's improvements in these biomarkers surpassed the control group's(P<0.05,P<0.01).No treatment-related adverse events occurred in either group.CONCLUSION Weiyan Tongluo Granules ameliorate gastric mucosal pathology,clinical symptoms,psychological state,and quality of life in CAG patients without significant adverse effects.Its mechanism may involve sup-pressing the NF-κB pathway to reduce IL-1β and IL-6 expression,downregulating CDX2 to inhibit VIL1 and MUC2 transcription,thereby reversing the vicious cycle of inflammation-intestinal metaplasia.

Objective:To systematically analyze the risk factors for knee injury complicated with adolescent tibial tubercle fractures (ATTF).Methods:A retrospective study was conducted to analyze the clinical data of the 90 adolescent patients (the observation group) who had been treated and fully followed up for knee injury complicated with ATTF at Department of Pediatric Orthopedics, The Second General Hospital of Fuzhou from September 2017 to April 2024. There were 86 males and 4 females, with a mean age of 14.0 (13.0, 14.0) years. The injury was on the left side in 51 cases, on the right side in 34 ones, and on the bilateral sides in 5 ones. All their injuries resulted from sports activities. In addition, another contemporary 90 patients with knee injury but no exercise-induced ATTF were enrolled as the control group, including 54 males and 36 females with a mean age of 14.0 (13.0, 14.3) years. Their injury was on the left side in 45 cases, on the right side in 41 ones, and on the bilateral sides in 4 ones. Univariate analysis was conducted to compare gender, age, injury side, height, weight, body mass index, history of Osgood-Schlatter disease (OSD), and injury mechanism between the 2 groups. Variables with P<0.1 were included in a multivariate logistic regression analysis to screen independent risk factors for ATTF. The receiver operating characteristic (ROC) curve was used to evaluate their predictive values. The optimal cutoff value was determined by Youden index. Results:The univariate analysis showed that gender, height, weight, body mass index, and OSD history were significantly correlated with the occurrence of ATTF ( P<0.05). The multivariate logistic regression analysis further confirmed that male ( P=0.017), height ( P=0.021), weight ( P=0.014), body mass index ( P=0.032) and history of OSD ( P=0.003) were independent risk factors for ATTF. The ROC curve analysis showed that weight had the largest area under the curve (AUC) in prediction of the ATTF risk, suggesting that its predictive value was the most significant. Conclusion:Male, height, weight, body mass index, and prior OSD are independent risk factors for ATTF, with the highest predictive value in weight.

Objective To explore the mechanisms of mesenchymal stem cell-derived extracellular vesicles (MSC-EVs) in improvement of renal injury in rats with diabetic nephropathy (DN) by regulating mammalian target of rapamycin (mTOR)/p70 ribosome protein S6 kinase (S6K1)/coiled-coil myosin-like Bcl-2-interacting protein (Beclin 1) pathway. Methods The model of SD rats with DN was established by a method of high-fat diet combined with intraperitoneal injection of streptozotocin, and they were randomly divided into model group, MSC-EVs group, and MSC-EVs+MHY1485 (mTOR activator) group, with 12 rats in each group. Another 12 SD rats were normally fed for 6 weeks and then intraperitoneally injected with an equal dose of sodium citrate solution as controls. After grouping with MSC-EVs and MHY1485, blood glucose and levels of renal function indicators [blood urea nitrogen (BUN), serum creatinine (Scr), and urinary microalbumin (UmALB)] in rats were detected. HE staining was used to detect the pathological morphology of renal tissue in rats of each group; immunohistochemistry was used to detect the expression of mTOR/S6K1/Beclin 1 pathway related proteins in the renal tissues of rats in each group; the Western blot was used to detect the mTOR/S6K1/Beclin 1 pathway and autophagy-related protein expression in the renal tissues of rats in each group. Results Compared with the control group, the renal tissue morphology of rats in the model group were impaired, and the blood glucose, BUN, Scr, UmALB, relative positive expressions of p-mTOR and p-S6K1, p-mTOR/mTOR, p-S6K1/S6K1 increased significantly (P < 0.05), while microtubule associated protein 1A/1B light chain 3 (LC3) Ⅱ/LC3Ⅰ, expression of Beclin 1 protein, and relative positive expression of Beclin 1 significantly reduced (P < 0.05); compared with the model group, the MSC-EVs group had less impairment in the renal tissue morphology, and the blood glucose, BUN, Scr, UmALB, relative positive expressions of p-mTOR and p-S6K1, p-mTOR/mTOR, and p-S6K1/S6K1 decreased significantly (P < 0.05), while expression of LC3Ⅱ/LC3Ⅰ, Beclin 1 protein, and relative positive expression of Beclin 1 increased significantly (P < 0.05); compared with the MSC-EVs group, the impairment of the renal tissue morphology was worse in the MSC-EVs+MHY1485 group, and the blood glucose, BUN, Scr, UmALB, relative positive expressions of p-mTOR and p-S6K1, expression of p-mTOR/mTOR, and p-S6K1/S6K1 increased significantly (P < 0.05), while the expression of LC3Ⅱ/LC3Ⅰ, Beclin 1 protein, and relative positive expression of Beclin 1 decreased significantly (P < 0.05). Conclusion MSC-EVs can enhance autophagy, reduce levels of blood glucose, Scr, BUN and urinary protein in rats with DN, alleviate renal tissue damage, and the mechanism may be achieved by inhibiting the activation of the mTOR/S6K1/Beclin 1 pathway.

Objective To construct N6-methyladenosine related long non-coding RNA(LncRNA)pairing model for renal cell carcinoma based on bioinformatics analysis of the cancer ganome atlas(TCGA)database and to explore its prognosis value.Methods Transcriptome data of RNA-sep for renal cell carcinoma and its related clinical information were downloaded from the TCGA database.Perl software was used to organize and separate LncRNA and messenger RNA(mRNA)from the transcriptome data.A total of 564 tissues from renal cell carcinoma cases and 72 normal tissues were obtained,and thus 540 renal cancer patients were eventually included.Random data table method was used to divide 540 patients with renal cancer into a training group(n=275)and a validation group(n=265)by caret.M6A related LncRNA pairing models were established based on the single factor and multivariate COX regression analysis.The risk assessment equation was obtained using the LASSO regression algorithm.The risk scores were calculated based on this equation,and the optimal critical point of the median risk value was applied to divide all patients into high-risk and low-risk groups.Kaplan-Meier survival analysis was used to make a survival curve for the differences between high and low risk groups in the overall sample.The gene ontology(GO)and Kyoto encyclopedia of genes and genomes(KEGG)pathway enrichment analyses were conducted using the Cluster Profiler software package.The relationship between N6-methyladenosine related LncRNA pairing model and immune cell infiltration was analyzed by R software.Results Kaplan-Meier survival analysis showed the total survival time of patients in the low-risk group was significantly higher than that of patients in the high-risk group of the training group(P<0.05).Compared with high risk group,the overall survival time of patients(G1～2,G3～4,Ⅰ～Ⅱ,or Ⅲ～Ⅳ,age≤65 years,or patients>65 years old)in low risk group was higher(P<0.05).Differential gene enrichment analysis was obtained for high and low risk groups,which mainly enriched with many differential genes such as muscle contraction,rhabdomytic cell differentiation,myofibril,receptor activation activity,and vascular smooth muscle contraction.The highest driver genes in high risk group and low risk group exhibited mutation frequency and mutation information,and their risk score was positively correlated with the degree of T cell and plasma cell infiltration(r=0.638,P=0.001).Conclusion Bioinformatics-based analysis of the N6-methyladenosine related LncRNA pairing models can be helpful to predict the prognosis of patients with renal cancer.It provides new ideas for the prognosis evaluation and optimal treatment strategy of renal cancer,and contributes to further analyzing the molecular mechanism of the occurrence and development of gastric cancer in the future.

Objective:To compare the efficacy between Kirschner wire and clavicular hook plate in the fixation of distal clavicle fractures in older children.Methods:A retrospective analysis was conducted of the 28 pediatric patients with distal clavicle fracture who had undergone surgical treatment at Department of Pediatric Orthopedics, The Second General Hospital of Fuzhou from December 2014 to December 2023. There were 20 boys and 8 girls. Age: 10.0 (9.0, 12.8) years old; 22 left sides and 6 right sides; by the Craig modified Neer classification: 22 cases of type Ⅱ, 5 cases of type Ⅳ, and 1 case of type Ⅴ. The patients were divided into 2 groups based on their internal fixation methods. The Kirschner wire group of 12 cases were treated with open reduction and Kirschner wire fixation; the hook plate group of 16 cases were treated with open reduction and clavicular hook plate fixation. Operation time, hospital stay, fracture healing time, incidence of complications, and scores at the final follow-up (the Constant-Murley shoulder function score, quick disabilities of the arm, shoulder, and hand (quickDASH) score, and visual analog scale (VAS) for aesthetic satisfaction) were recorded and compared between the 2 groups.Results:There were no statistically significant differences in the baseline data between the 2 groups, indicating comparability ( P>0.05). The postoperative follow-up period for the 28 patients was (14.8±6.5) months. The operation time in the Kirschner wire group [(34.3±12.1) min] was significantly shorter than that in the hook plate group [(49.4±16.8) min] ( P<0.05), and the VAS score for aesthetic satisfaction at the final follow-up in the Kirschner wire group [(8.2±1.1) points] was significantly higher than that in the hook plate group [(6.2±2.6) points] ( P<0.05). There were no statistically significant differences between the 2 groups in terms of fracture healing time, hospital stay, incidence of complications, or Constant-Murley score and quickDASH score at the final follow-up ( P>0.05). Conclusions:For pediatric patients with distal clavicle fracture, both Kirschner wire fixation and clavicular hook plate fixation can achieve good functional outcomes. However, Kirschner wire fixation has advantages of shorter operation time, higher postoperative aesthetic satisfaction, and no need of a secondary surgery for implant removal.

Objective:To analyze the risk factors for ankle varus deformity after McFarland fracture surgery in children.Methods:A total of 48 children with McFarland fracture who underwent surgical treatment in the Second General Hospital of Fuzhou from January 2015 to December 2022 were retrospectively analyzed, including 24 males and 24 females, aged 11.2±3.2 years (range, 2-14 years), 19 cases on the left side and 29 cases on the right side. Salter-Harris classification: 34 cases of type III and 14 cases of type IV. Causes of injuries: 28 cases of sports injuries, 15 cases of fall injuries, and 5 cases of car accident injuries. The time from injury to operation was 2.6±1.7 d (range, 1-7 d). The reduction methods included closed reduction in 38 cases and open reduction in 10 cases. Tibial internal fixation: 42 cases of hollow screws, 6 cases of Kirschner pins. There were 30 cases of combined fibula fracture, 20 cases were fixed with plate, 8 cases were fixed with Kirschner's pin, and 2 cases were not treated with internal fixation. The internal fixation survival time was 6.4±2.8 months (range, 1-12 months). The lateral distal tibial angle (LDTA) was used to determine whether the child had ankle varus deformity. The general data and perioperative indicators of the two groups were compared, and the indicators with statistically significant differences were included in binary logistic regression analysis to determine the independent risk factors for ankle varus deformity after McFarland fracture surgery in children. The receiver operating characteristic curve was drawn and the area under the curve of each independent risk factor was calculated.Results:All patients successfully completed the operation and were followed up for 39.2±21.8 months (range, 15-98 months). At the last follow-up, all the 48 children with McFarland fracture had bone union and the internal fixation was successfully removed, and 5 of them had ankle varus deformity. The LDTA of the affected side was 98.6°±4.8° (range, 94°-106°) in the ankle varus deformity group and 89.0°±0.8° (range, 87°-91°) in the non-ankle varus deformity group. The age of children in the ankle varus deformity group was 6.6±5.1 years, which was younger than that in the non-ankle varus deformity group (11.7±2.5 years), and the difference was statistically significant ( t=3.772, P<0.001). The survival time of internal fixation in the ankle varus deformity group was 4.4±2.2 months, which was shorter than that in the non-ankle varus deformity group (6.6±2.8 months), and the difference was statistically significant ( t=1.750, P=0.087). There was no significant difference in gender, side, cause of injury, fracture type, initial displacement distance, fibular fracture, time from injury to operation, reduction method, or fixation method between the two groups ( P>0.05). Age and duration of internal fixation were included in binary logistic regression analysis. The results showed that age ( OR=0.717, 95% CI: 0.543, 0.945, P=0.018) was an independent risk factor for postoperative ankle varus deformity in children with McFarland fracture. The receiver operating characteristic curve of independent risk factors predicting postoperative ankle varus deformity in children with McFarland fracture was drawn and the area under the curve was calculated. The results showed that the best cut-off value of age was 5.5 years, and the area under the curve was 0.807, and the prediction efficiency of the prediction model was good. Conclusion:Age<5.5 years is an independent risk factor for postoperative varus ankle deformity in children with McFarland fracture.

Background: Cervical cancer is still present a major public health problem, especially in developing countries. In International Federation of Gynaecology and Obstetrics 2018, allowing assessment of retroperitoneal lymph nodes by imaging and/or pathological findings and, if deemed metastatic, the case is designated as stage IIIC (with r and p notations). Patients with lymph node metastases have lower overall survival (OS), progression free survival (PFS), and survival after recurrence, especially those who have unresectable macroscopical positive lymph nodes. Retrospective analysis suggests that there may be a benefit to debulking macroscopic nodes that would be otherwise difficult to sterilize with standard doses of radiation therapy. However, there are no prospective study reporting that resecting macroscopic nodes before concurrent chemoradiation therapy (CCRT) would improve PFS or OS of cervical cancer and no guidelines for surgical resection of bulky lymph nodes. The CQGOG0103 study is a prospective, multicenter and randomized controlled trial (RCT) evaluating lymph node dissection on stage IIICr of cervical cancer. Methods Eligible patients are histologically confirmed cervical squamous cell carcinoma, adenocarcinoma, adeno-squamous cell carcinoma. Stage IIICr (confirmed by computed tomography [CT]/magnetic resonance imaging/positron emission tomography/CT) and the short diameter of image-positive lymph node ≥15 mm. 452 patients will be equally randomized to receive either CCRT (pelvic external-beam radiotherapy [EBRT]/extended-field EBRT + cisplatin [40 mg/m2] or carboplatin [the area under curve=2] every week for 5 cycles + brachytherapy) or open/minimally invasive pelvic and para-aortic lymph node dissection followed by CCRT. Randomization is stratified by status of para-aortic lymph node. The primary endpoint is PFS. Secondary endpoints are OS and surgical complications. A total of 452 patients will be enrolled from multiple hospitals in China within 4 years and followed up for 5 years.

Objective:To investigate the effects of hyperuricemia on the prognosis of IgA nephropathy (IgAN) using propensity score matching (PSM) method.Methods:IgAN patients proven by biopsy were included. PSM was used to match patients. Kaplan-Meier method was used for survival analysis, and Cox regression analysis was used to analyze the effects of hyperuricemia on IgAN prognosis. Primary outcome events were defined as death, or end-stage renal disease (dialysis, transplantation), or a decrease in estimated glomerular filtration rate (eGFR) greater than 40%. Renal outcome was defined as end-stage renal disease (dialysis, transplantation), or a decrease in eGFR greater than 40%.Results:A total of 1 454 IgAN patients were included in this study, including 850 females and 604 males. Uric acid level was (368.26±92.87) μmol/L in the males, and (277.23±92.71) μmol/L in the females. The median follow-up time was 85.00(56.10, 106.33) months. During the follow-up period, a total of 134 patients reached the primary outcome events, including 5 deaths, 24 dialysis patients, 5 kidney transplant patients, and 100 patients with eGFR decreased by more than 40%. After 1∶1 matching, 131 males and 159 females in the hyperuricemia group were successfully matched with 131 males and 159 females in the normal uric acid group, and there was no significant statistical difference in each parameter in baseline between the hyperuricemia group and normal uric acid group after matching. Kaplan-Meier survival analysis showed that either before or after matching, the incidence of primary outcome events in male or female patients with hyperuricemia was higher than those with normal uric acid, but there was no statistically significant difference in incidence of primary outcome events between female hyperuricemia group and female normal uric acid group after matching (Log-rank test, χ2=3.586, P=0.058). Cox proportional hazard regression model showed that, in the pre-match fully adjusted model, the hazard ratio ( HR) of entering primary outcome events was 2.29-fold (95% CI 1.27-4.11, P=0.006) for men with hyperuricemia and 1.85-fold (95% CI 1.01-3.37, P=0.045) for women with hyperuricemia compared with those with normal uric acid. In the post-match fully adjusted model, the HR of entering primary outcome events was 2.41-fold (95% CI 1.18-4.93, P=0.016) for men with hyperuricemia and 1.83-fold (95% CI 0.91-3.67, P=0.091) for women with hyperuricemia compared with those with normal uric acid. In the pre-match fully adjusted model, the HR of entering renal outcome events was 2.68-fold (95% CI 1.47-4.88, P=0.001) for men with hyperuricemia and 1.81-fold (95% CI 0.99-3.33, P=0.056) for women with hyperuricemia compared with those with normal uric acid. In the post-match fully adjusted model, the HR of entering renal outcome events was 2.89-fold (95% CI 1.36-6.15, P=0.006) for men with hyperuricemia and 1.81-fold (95% CI 0.88-3.72, P=0.106) for women with hyperuricemia compared with those with normal uric acid. Conclusion:Hyperuricemia may be associated with IgAN progression, and it has a more significant effect on male IgAN patients.
