Objective: To analyze the association of participation in non-sports extracurricular tutoring classes with the prevalence of screening myopia, axial length (AL) and axial length to corneal radius ratio (AL/CR) among primary school students, so as to provide evidences for formulating myopia prevention and control policies. Methods: In December 2024, combination of convenience and cluster sampling method was used to select 2 273 students from two primary schools in Hefei City, Anhui Province. Ophthalmic examinations and questionnaire surveys were conducted to obtain information on myopia, AL, AL/CR and participation in various types of extracurricular tutoring. A binary Logistic regression model was used to analyze the association between non-sports tutoring and screening myopia, and multiple linear regression models were used to examine the associations between non-sports tutoring and AL and AL/CR. Results: Among the surveyed students, the participation rate in non-sports extracurricular tutoring classes was 64.9% , and the overall prevalence of screening myopia was 39.1%. The average AL and AL/CR were (23.60± 1.01 ) mm and (3.00±0.12), respectively. Univariate analysis showed that students who attended non-sports, music, or academic tutoring classes for ≥2 h per week had higher risks of screening myopia and greater AL/CR values than non-participants (screening myopia: OR =1.38, 1.82, 1.55; AL/CR: β =0.01, 0.03, 0.03; all P <0.05). After adjusting for sex, grade, and participation in sports tutoring, multivariate analysis indicated that participation in non-sports and musical instrument tutoring classes for ≥2 h per week remained significantly associated with higher risks of screening myopia ( OR =1.26, 1.49, both P <0.05). Multiple linear regression showed that participation in musical instrument tutoring for ≥2 h per week was positively correlated with AL ( β=0.14, P < 0.05). Conclusions Participation in non-sports extracurricular tutoring is common among primary school students. Attending non-sports tutoring classes for ≥2 h per week increases the risk of screening myopia.

Sustained inflammatory responses are closely related to various severe diseases, and inhibiting the excessive activation of inflammasomes and pyroptosis has significant implications for clinical treatment. Natural products have garnered considerable concern for the treatment of inflammation. Huanglian-Wumei decoction (HLWMD) is a classic prescription used for treating inflammatory diseases, but the necessity of their combination and the exact underlying anti-inflammatory mechanism have not yet been elucidated. Inspired by the supramolecular self-assembly strategy and natural drug compatibility theory, we successfully obtained berberine (BBR)-chlorogenic acid (CGA) supramolecular (BCS), which is an herbal pair from HLWMD. Using a series of characterization methods, we confirmed the self-assembly mechanism of BCS. BBR and CGA were self-assembled and stacked into amphiphilic spherical supramolecules in a 2:1 molar ratio, driven by electrostatic interactions, hydrophobic interactions, and π-π stacking; the hydrophilic fragments of CGA were outside, and the hydrophobic fragments of BBR were inside. This stacking pattern significantly improved the anti-inflammatory performance of BCS compared with that of single free molecules. Compared with free molecules, BCS significantly attenuated the release of multiple inflammatory mediators and lipopolysaccharide (LPS)-induced pyroptosis. Its anti-inflammatory mechanism is closely related to the inhibition of intracellular nuclear factor-kappaB (NF-κB) p65 phosphorylation and the noncanonical pyroptosis signalling pathway mediated by caspase-11.

Objective:To investigate the clinical safety and efficacy of robot-assisted laparoscopic ventral onlay lingual mucosal graft ureteroplasty for ureteral stricture.Methods:The clinical data of 6 patients with ureteral stricture admitted to the Guizhou Provincial People's Hospital from December 2020 to August 2022 were retrospectively analyzed. There were 3 males and 3 females, with an average age of (40.2±11.5) years old. The status of ureteral stricture and hydronephrosis was measured by ultrasonography, CT urography and ureteral retrograde angiography. There were 2 cases of left ureteral stricture and 4 cases of right ureteral stricture, including 4 cases of upper segment stricture and 2 cases of middle segment stricture. The separation of the renal pelvis on the affected side was 3.2 (2.1, 4.2) cm. The length of ureteral stricture was 3.8 (2.5, 4.3) (1.0-5.0) cm, and the preoperative blood creatinine was 90(71, 97)μmol/L. Robot-assisted laparoscopic ventral onlay lingual mucosal graft ureteroplasty was performed in all cases under general anesthesia. The strictured ureter segment was separated and longitudinally cut during the operation. The lingual mucosal grafts 2.5-5.0 cm in length and 1.0-1.5 cm in width was cut according to the stricture. Then the lingual mucosal grafts were harvested and placed in the strictured ureter as a ventral onlay. One double J tube was placed in the affected side in all cases during operation. The perioperative outcomes and complications were analyzed. The blood creatinine and renal pelvis separation on the affected side after surgery were compared with the preoperation.Results:All the surgeries were successfully completed. The average operative time was (190.8 ± 59.0) min, median blood loss was 40 (20, 63) ml, postoperative indwelling time of the drainage tube was 6 (4, 6) days, gastrointestinal function recovery time was 3 (2, 3) days, postoperative hospital stay was 6 (6, 7) days. The patients had clear pronunciation and lingual incision recovered 1 week post-operatively. The urine tube was removed 2 weeks after surgery, and the double J tube was removed 8 (6, 10) weeks post-operatively. Radiological examination revealed significant difference in hydronephrosis on the affected side 3 months post-operatively compared with the preoperation, and the separation of the renal pelvis on the affected side was 1.2 (1.2, 1.4) cm after surgery. The blood creatinine was 79(71, 104)μmol/L at 3 month after surgery, which was also improved compared with preoperative.Conclusions:Robot-assisted laparoscopic ventral onlay lingual mucosal graft ureteroplasty is a feasible and safe option for the treatment of ureteral stricture with less trauma, rapid recovery, and less complications.

ObjectiveTo investigate the contamination status of Staphylococcus aureus in food and the presence of enterotoxin genes in Jiading District， Shanghai， and to provide a basis for the prevention and treatment of foodborne Staphylococcus aureus disease. MethodsFrom 2021 to 2023， 15 types of food were sampled for S. aureus testing， and the presence of five enterotoxin genes， including sea⁃see， was tested in the strains. ResultsOut of 705 food samples， 88 （12.48%） were positive for S. aureus. S. aureus was detected in 12 of the 15 food types， with the three food types with the highest positive rates being cold noodles （45.00%）， raw poultry （26.25%）， and vegetable salads （20.00%）. The enterotoxin gene carriage rate was 32.95% in food strains. The carriage rates for sea， seb， and sec were 7.95%， 12.50%， and 14.77%， respectively. Neither sed nor see was detected. The detection rate of strains carrying two types of enterotoxin genes was 2.27%. The enterotoxin carriage rates in strains from vegetables， beverages， and raw meat were 57.14%， 40.00%， and 30.00%， respectively. ConclusionThe S. aureus detection rate in food in Jiading District is much higher than the national average. The enterotoxin gene carriage rates are high， with food strains carrying sea， seb， and sec， with sec being the most prevalent. There is a need to enhance monitoring of S. aureus and enterotoxins， especially in high-risk foods such as noodles， vegetables， and non-packaged beverages.

And the FLP was detected for FⅤ∶C, FⅧ∶C, Fib, TP and Alb at 1, 2, 3, 4, 5, 6, 7 days and 1, 6, 11, 16, 21, 26 and 31 days after preparation, respectively. 【Results】 In FFP group, FⅧ∶C decreased gradually with the prolongation of storage time after melting (P<0.05), and decreased by 37.4% and 47.6% respectively in the two groups on the 7th day. There was no statistical difference in FⅤ∶C, Fib, TP and Alb (P>0.05). In FLP group, FⅧ∶C decreased gradually with the prolongation of storage time after melting (P<0.05). There was no statistical difference in FⅤ∶C in 7-day storage group (P>0.05), but it decreased gradually in 31-day storage group (P<0.05). There was no statistical difference in Fib, TP and Alb (P>0.05). 【Conclusion】 Although FⅧ∶C is decreased in thawed FFP stored at 2-6℃ for 7 days, it is still about 52.4%, which should be able to play a normal role in clinical practice.

Granulocytic myeloid-derived suppressor cells(G-MDSCs)are one of the main subgroups of MD-SCs,which are widely enriched in most cancers.It can inhibit the killing function of T-lymphocyte through the expression of arginase-1(Arg-1)and reactive oxygen species(ROS),reshape the tumor immune microenvironment,and promote the oc-currence and development of tumors.In recent years,more and more studies have found that G-MDSCs are significantly cor-related with the prognosis and immunotherapy efficacy of patients with non-small cell lung cancer,and the use of drugs specifi-cally targeting the recruitment,differentiation and function of G-MDSCs can effectively inhibit tumor progression.This article reviews the immunosuppressive effect of G-MDSCs in non-small cell lung cancer and the progress of related pathway targeting drugs.

Objective·To investigate the predictive value of the Clinical Frailty Scale(CFS)in the long term outcomes in acute myocardial infarction(AMI)patients who completed in-hospital cardiac rehabilitation(CR).Methods·A total of 501 AMI patients treated in the Cardiology Center of Shanghai Sixth People's Hospital,Shanghai Jiao Tong University of Medicine from May 2020 to May 2022 were prospectively enrolled,with their baseline clinical data collected.The patients completed graded in-hospital CR and were assessed by CFS based on their completion of CR before discharge.Patients were then categorized into three groups(norm group,vulnerable group and frail group)according to their CFS level.The difference in 1-year major cardiovascular event(all-cause death and re-hospitalization for heart failure)rates among the three groups was investigated.Logistic regression analysis was performed to explore the effective risk factors relevant to the outcomes,and receiver operator characteristic(ROC)curves were generated to analyze the prognostic value.Finally,an optimal prediction model was developed.Results·The CFS level in AMI patients who completed CR was positively correlated with age and peak pro-B-type natriuretic peptide(peak proBNP),and inversely correlated with gender difference(P<0.05).Accompanied with the elevated CFS level,the incidence of both outcomes increased,and there were significant differences in all-cause death(2.6%,5.6%and 15.2%,P=0.002),and while no significant differences in re-hospitalization for heart failure among the three groups(19.6%,22.2%and 24.2%).All-cause death of the frail group was significantly higher than that of the norm group(P=0.004),while there was no significant difference between the vulnerable group and the norm group.CFS could sensitively predict the 1-year all-cause death in AMI patients(β=1.89,OR=6.61,P=0.001),and the risk model combined with CFS had the best predictive effect(AUC=0.845,P=0.000).Conclusion·Assessment by CFS in AMI patients who completed in-hospital CR contributes to identifying AMI patients with high risk of all-cause death in 1 year.

Objective To evaluate the value of a machine learning-based biparametric magnetic resonance imaging(bpMRI)radiomics model in predicting clinically significant prostate cancer(csPCa)in the transitional zone.Methods A retrospective analysis was con-ducted on 507 cases in two medical centers.All patients underwent prostate MRI examinations before surgery,with complete patho-logical data.The case distribution was as follows:256 cases of csPCa,97 cases of clinically insignificant prostate cancer(ciPCa),and 154 cases of benign prostatic hyperplasia(BPH).Using the R language,the data from Center One was randomly divided into training and test groups at a ratio of 7∶3,and the data from Center Two as an independent external validation group.The image features from T2 WI and diffusion weighted imaging(DWI)were extracted,and the least absolute shrinkage and selection operator(LASSO)was used to reduce dimensionality and filter features.Two datasets were constructed based on T2 WI features alone and combined T2 WI and DWI features.Six prediction models were established using random forest(RF),logistic regression(LR),and support vector machine(SVM).The efficacy of six models of T2 WI features and combined T2 WI and DWI features in the diagnosis of prostate dis-eases through receiver operating characteristic(ROC)curve,area under the curve(AUC),and decision curve analysis(DCA)were compared and evaluated.Results In the training group,feature screening identified 7 and 8 features from the T2WI single sequence and the T2WI with DWI dual sequence for csPCa prediction in the transitional zone.The results showed that the T2WI with DWI dual sequence RF model had the highest AUC performance.The AUC of the training,test,and validation groups were 0.950,0.866,and 0.818,respectively.The test group accuracy was 0.805,sensitivity was 0.690,and specificity was 0.920;the validation group accu-racy was 0.726,sensitivity was 0.661,and specificity was 0.793.DCA showed that within a wide probability threshold range,the T2 WI with DWI dual sequence RF model had the greatest net benefit.Conclusion Based on the bpMRI radiomics model,non-invasive prediction of csPCa in the transitional zone can be achieved before surgery,which helps to make clinical diagnosis and treatment decisions.

Objective To analyze the clinical characteristics of children with hand,foot and mouth disease(HFMD)infected with different enterovirus subtypes and construct a risk nomogram prediction model to provide basis for HFMD prevention and treatment.Meth-ods The clinical data of 346 cases of children hospitalized with HFMD in Shanxi Children's Hospital(Shanxi Maternal and Child Health Hospital)from 2017-2021 were collected and divided into Coxsackie virus A16 group(n=26),enterovirus 71 group(n=56)and en-terovirus general group(n=264)according to different enteroviruses,and the clinical characteristics were compared between the three groups to construct a risk nomogram model in children with HFMD combined with brainstem encephalitis to validate the prediction effect of the model.Results The age of children with HFMD was mainly distributed between 1 and 3 years(81.21％),with a male to female ra-tio of 1.56∶1,with a primary peak of incidence in June to August and a secondary peak in October to November,with enterovirus 71 type infections predominating in 2017 and enterovirus general infections in 2018-2021.The differences were statistically significant in age,days of hospitalization,presence of fever,fever typing,days of fever duration,herpes,maculopapular rash,oral rash,knee rash,white blood cell,platelet count,C-reactive protein and procalcitonin among the three groups(P＜0.05).The occurrence of HFMD combined with brainstem encephalitis in children was positively correlated with longer days of hospitalization and fever duration,papular rash and en-terovirus 71 positivity,and negatively correlated with longer days of rash(P＜0.05).The nomogram model showed that the probability of occurrence of childhood HFMD combined with brainstem encephalitis was 85.6％,the area under the receiver operating characteristic curve was 0.860.The calibration curve showed that the actual probability was in good agreement with the predicted probability,and the decision curve showed that the net gain of the model essentially to the full threshold probability was obvious.Conclusion HFMD in chil-dren has obvious seasonality with double peaks,enterovirus general type is the dominant pathogen of HFMD in recent years,the clinical characteristics of infection with different enteroviruses are different,the risk nomogram model has good early prediction effect on HFMD combined with brainstem encephalitis in children,and has high clinical application value,which is important for the prevention,diagnosis and treatment of HFMD in children.

ObjectiveTo investigate the contamination status and drug resistance of Campylobacter spp. in poultry sold in Jiading District， Shanghai. MethodsFour types of poultry meats （chickens， ducks， geese and pigeons） were sampled from commercial markets， and potential Campylobacter spp. contamination was isolated and identified. Furthermore， resistance of isolated Campylobacter spp. to 15 commonly used antibiotics was tested. ResultsTotally 29 Campylobacter jejuni strains and 34 Campylobacter. coli were isolated from 236 commercial poultry samples. The most severe contamination of Campylobacter spp. was found in chicken samples， with a detection rate of 34.04%， while the lowest detection rate of Campylobacter spp. was found in duck （19.67%）. Contamination status was categorized with different storage conditions. The lowest detection rate of 6.67% was noted under frozen condition， while highest detection rate of 41.27% was noted under cold storage. Campylobacter jejuni was completely resistant to cefazolin， ciprofloxacin， nalidixic acid and tetracycline， and Campylobacter coli was completely resistant to cefazolin， cefoxitin and nalidixic acid； Campylobacter spp. showed the lowest resistance to imipenem. Multi-drug resistant strains accounted for 100.00% of the isolated strains. 96.83% of the strains were resistant to more than 5 drugs， with the highest number reaching 14 kinds of antibiotics. ConclusionThere is a significant difference in the contamination status and drug resistance of Campylobacter spp. isolated from four types of poultry meats sold in Jiading District， Shanghai， and the drug resistance is serious. It is strongly recommended that the use of antibiotics should be strictly controlled. Freezing can effectively reduce Campylobacter spp. pollution.
