OBJECTIVE: To explore the effectiveness of arthroscopic release of elbow joint assisted by medial small incision ulnar nerve release in the treatment of non-traumatic elbow stiffness. METHODS: The clinical data of 15 patients with non-traumatic elbow stiffness treated with arthroscopic release of elbow joint assisted by medial small incision ulnar nerve release between April 2019 and September 2023 were retrospectively analyzed. There were 6 males and 9 females with an average age of 46 years ranging from 34 to 56 years. The causes included rheumatoid arthritis in 3 cases, gouty arthritis in 2 cases, loose bodies in 3 cases, and elbow osteoarthritis in 7 cases. There were 4 cases with ulnar neuritis and 3 cases with synovial osteochondromatosis. The duration of elbow stiffness ranged from 6 to 18 months, with an average of 10 months. The operation time and intraoperative blood loss were recorded. The effectiveness was evaluated by visual analogue scale (VAS) score, range of elbow motion (maximum flexion, maximum extension, and total flexion and extension), Mayo score, and Hospital for Special Surgery (HSS) elbow score. RESULTS: The operation time was 60-90 minutes, with an average of 65 minutes, and the intraoperative blood loss was 40-100 mL, with an average of 62 mL. All patients were followed up 13-18 months, with an average of 14 months. There was no complication such as vascular and nerve injury, poor wound healing, collateral ligament injury, elbow joint space narrowing, osteophyte proliferation, or loose body formation around the joint. At last follow-up, the elbow range of motion (maximum flexion, maximum extension, and total flexion and extension), VAS score, and Mayo score significantly improved when compared with those before operation ( P<0.05). The HSS elbow score was 85-95, with an average of 92; 12 cases were excellent, 3 cases were good, and the excellent and good rate was 100%. CONCLUSION Arthroscopic release of elbow joint assisted by medial small incision ulnar nerve release is an effective way to treat non-traumatic elbow stiffness, which has the advantages of small trauma, short operation time, and good effectiveness. It can carry out early elbow rehabilitation training and significantly improve elbow function.

OBJECTIVE: To explore the effect of Lactobacillus reuteri on testicular injury in mice exposed to neonicotinoid insecticides (NNI). METHODS: Fifteen C57BL/6 male mice were randomly divided into control group (CTRL group), exposure group (NNI group) and Lactobacillus intervention group (NNI-L group). The mice in CTRL group were given 0.02ml/g of 0.5% carboxymethyl cellulose sodium solution by gavage for 14 days. The mice in NNI group were given 0.02 ml/g of NNI mixture by gavage for 14 days. The mice in NNI-L group were given 0.02 ml/g of NNI mixture by gavage and 5×108cfu/ml of Lactobacillus reuteri powder solution for 14 days. Then, the histomorphology and function of testicle were evaluated by hematoxylin-eosin staining, immunofluorescence staining and RNA sequencing. RESULTS: Compared with CTRL group, the thickness of testicular seminiferous epithelium in the NNI group was significantly thinner. And the decline in the number of spermatogenic cells and sperm was observed. And the expression of spermatogonial stem cell marker UCHL1 was down-regulated which was significantly improved in NNI-L group compared with the NNI group. The abnormal expressions of hormone and sperm methylation related genes in testis of NNI group were detected by RNA sequencing, with significant down-regulation being found in NPFF and IGF2. While the expression of HSD3B8 was significantly up-regulated. The abnormal expression of these genes could be significantly improved after oral administration of Lactobacillus reuteri. CONCLUSION Testicular spermatogenesis and endocrine function can be damaged by NNI exposure. And oral administration of Lactobacillus reuteri protects testis from the adverse effects of NNI toxicity.

OBJECTIVES: This study aims to evaluate the differences in shear bond strength, marginal adaptation, and nano-microleakage after aging among snowplow, layered filling, and lining techniques applied to the resin-bonded restoration of defective primary teeth. METHODS: In this study, 51 freshly extracted, crown-intact primary anterior teeth and 30 primary molars were collected. The experimental groups were as follows: layered filling group, lining group, and snowplow group. Experiments were performed to compare the differences in shear bond strength, marginal integrity, and silver ion nano-microleakage after aging among these groups. RESULTS: The median shear bond strength of the layered filling group, lining group, and snowplow group were 2.45, 5.72, and 9.43 MPa, respectively. The values for lining group and snowplow group were significantly higher than that for layered filling group (P<0.05). No statistically significant difference was found between lining group and snowplow group (P>0.05). The median overall margin integrity of the layered filling group, lining group, and snowplow group were 55.38%, 48.25%, and 65.63%, respectively. The difference among the three groups was not statistically significant (P>0.05). The median percentages of silver ion nano-microleakage in the layered filling group, lining group, and snowplow group were 11.71%, 9.47%, and 11.55%, respectively. The difference among the three groups was not statistically significant (P>0.05). CONCLUSIONS Applying the snowplow technique to restore defective primary teeth can improve the bond strength and margin integrity and reduce nano-microleakage.

Thrombosis is a key factor that increases the mortality rate of COVID-19 patients and causes long COVID sequelae. Guanxinning Tablet (GXNT), which is composed of Salvia miltiorrhiza and Ligusticum Chuanxiong, has significant antithrombotic activity, but the similarities and differences between its anti-conventional thrombus and microthrombus induced by COVID-19 remain unclear. In this paper, the main active components, potential targets and mechanisms of GXNT in the treatment of thrombus and microthrombus caused by COVID-19 were preliminarily revealed by using anti-platelet experiments in vitro, network pharmacology analysis, molecular docking technology and molecular biology experiments. The results of platelet aggregation and adhesion experiments in vitro showed that GXNT had significant anti-platelet aggregation and adhesion activities in a dose-dependent manner. Using network pharmacology analysis, it was revealed that salvianolic acid B, tanshinone IIA, caffeic acid and ligustrazine in GXNT could resist thrombus and microthrombus caused by COVID-19 through key targets as the high mobility group box 1 protein (HMGB1), tumor necrosis factor (TNF), interleukin 6 (IL6) and AKT serine/threonine kinase 1 (AKT1). HMGB1 signaling pathway is one of its key common mechanisms. Western blot also indicated that GXNT significantly inhibited the expression of HMGB1 protein in platelets. In summary, this paper explores the similarities and differences between the mechanism of GXNT against conventional thrombus and microthrombus caused by COVID-19 and provides drug reference and theoretical basis for clinical prevention and treatment of long COVID sequelae. The animal experiment has been approved by the Experimental Animal Ethics Committee of Tianjin University of Traditional Chinese Medicine (No. TCM-LAEC2023187g1549).

Objective To analyze the factors associated with pain after arthroscopic rotator cuff bridge suture.Methods According to the inclusion and exclusion criteria,the data of 112 patients with unilateral rotator cuff injury who received arthroscopic bridge suture in our department were collected and were investigated in the form of telephone follow-up.In this study,SPSS 23.0 was used to input data and conduct statistical analysis.Logistic regression analysis was used to analyze the correlation between the above influencing factors and postoperative pain.Results A total of 112 patients were included for statistical analysis,single factor analysis revealed,including course of disease,smoking history,preoperative University of California,Los Angeles(UCLA)score,Constant score,numeric rating scale(NRS),size of rotator cuff tear,whether it was full-thickness tear and degree of tendon retraction might be related to postoperative pain(P<0.05).The age,gender,body mass index(BMI),drinking history,diabetes and hypertension were not related to postoperative pain(P>0.05).Multiple linear regression analysis concluded that there were four factors related to postoperative pain,and the correlation degree was preoperative NRS,preoperative UCLA score,tear size and smoking history.Conclusion The causes of postoperative pain after arthroscopic rotator cauff repair are complex and diverse.Analyzing the cause of postoperative pain can effectively reduce the pain of patients and promote the recovery of shoulder joint function.

Objective To investigate the changes in distribution of Oncomelania hupensis snails in forestlands in Songjiang District, Shanghai Municipality from 2009 to 2023, so as to provide insights into formulation of O. hupensis snail surveillance programs. Methods The reports on O. hupensis snail surveillance in Songjiang District, Shanghai Municipality from 2009 to 2023 were collected, and the snail surveillance data in forestlands were extracted. The trends in the proportion of areas with snails in forestlands in total areas with snails, occurrence of frames with living snails and density of living snails were evaluated using a Joinpoint regression model in Songjiang District from 2009 to 2023, and the annual percent change (APC) and average annual percent change (AAPC). Results A total of 40 sites with snails were found in forestlands in 14 administrative villages of 4 townships, Songjiang District, Shanghai Municipality from 2009 to 2023. A total of 39 065 frames were surveyed for snails in settings covering an area of 609 600 m², and there were 6 084 frames with snails, covering 151 250 m² snail habitats. A total of 22 210 snails were captured, with the highest density of 260.00 snails/0.1 m², and 6 262 snails were dissected, with no Schistosoma japonicum infection identified in snails. The proportion of areas with snails in forestlands in total areas with snails appeared a tendency towards a rise in forestlands in Songjiang District, Shanghai Municipality from 2009 to 2023 (APC = AAPC = 24.9%, P > 0.05); however, there were no turning points in the trend curve, with the highest proportion seen in 2009 (53.81%), the lowest in 2011 and 2023 (both 0) and a mean proportion of 24.81%. The occurrence of frames with living snails appeared a tendency towards a rise from 2009 to 2023 (APC = AAPC = 41.5%, P > 0.05); however, there were no turning points in the trend curve, with the highest occurrence in 2009 (53.81%), the lowest in 2011 and 2013 (both 0), and the mean occurrence of 15.57%. In addition, the density of living snails appeared a tendency towards a rise from 2009 to 2023 (APC = AAPC = 55.0%, P > 0.05); however, there were no turning points in the trend curve, with the highest density in 2023 (0.96 snails/0.1 m²), the lowest in 2011 and 2013 (both 0), and a mean density of 0.57 snails/0.1 m². Conclusions The difficulty in O. hupensis snail control and risk of imported snails appeared a tendency towards a rise in forestlands in Songjiang District, Shanghai Municipality over years from 2009 to 2023. Supervision and assessment prior to seedling transplantation and intensified surveillance post-transplantation are recommended to reduce the risk of O. hupensis snail importation and spread.

Objective To compare the therapeutic efficacy of whey protein powder in peritoneal dialysis hypoproteinemia patients.Methods From August 2019 to August 2020,100 patients with peritoneal dialysis hypoproteinemia from the Peritoneal Dialysis Center of the First Affiliated Hospital of Xi'an Jiaotong University were investigated.The patients were separated into 2 groups randomly;the study group were administered whey protein powder and the control group with high protein food.After 32 weeks of treatment,biochemical and biometric indices including hemoglobin(Hb),albumin(ALB),prealbumin(PA),triglyceride(TG),total cholesterol(TC),phosphorus(P),low density lipoprotein(LDL),high density lipoprotein(HDL),serum creatinine(Scr),blood urea nitrogen(BUN),estimated glo-merular filtration rate(eGFR),total spKt/Vurea(TKt/V),total creatinine clearance rate(TCcr),hand grip strength(HG),triceps skinfold(TSF),arm circumference(AMC),mid-arm muscle circumference(MAMC)were compared between groups.Results Compared with 0 week,at 16 and 32 weeks,ALB,PA,and HG were significantly increased in the study group(P＜0.05).Compared with the control group,ALB,PA,and HG increased significantly at 16 and 32 weeks in the study group(P＜0.05).There were no significant differences in TG,TC,HDL,LDL,eGFR,TKt/V,and TCcr at 0,8,16,and 32 weeks between the control and study groups(P＞0.05).Conclusion For patients with peritoneal dialysis hypoproteinemia caused by insufficient protein intake or excessive protein loss,the addition of whey protein during peritoneal dialysis can significantly improve the nutritional status of patients,with greater efficacy than a high protein diet alone.

Objective:To investigate the clinical effect of extraperitoneal robot-assisted laparoscopic modified Y-V plasty(LMYVP)in the treatment of refractory bladder neck contracture(BNC).Methods:We retrospectively analyzed the clinical data on 10 cases of refractory BNC after transurethral resection of the prostate between September 2020 and January 2023,all with a history of recurrent urethral dilatation and at least two failures in transurethral surgical treatment of scarring.After definite diagnosis and re-moval of some of the scar tissues to flatten the elevated bladder neck under the cystoscope,we performed robot-assisted LMYVP using the da Vinci Si robotic system and a four-port extraperitoneal approach.The surgical procedure involved an inverted T-shaped incision in the bladder neck and urethral stricture ring,an inverted V-shaped excision of the scar area at the 3-9 o'clock position on the ventral side of the prostatic urethra,continuous full-layer suturing of the bladder neck and inverted V-shaped urethra with 3-0 barbed thread,and indwelling of an F20 silicone catheter for 2 weeks.At 3 months after surgery,we performed cystoscopic examination,measured the maximum urinary flow rate(Qmax),and obtained the IPSS and quality of life(QOL)scores of the patients.Results:Operations were successfully completed in all the cases.At 3 months after surgery,the patients showed significantly increased Qmax([3.65±1.27]vs[20.3±1.77]ml/s,P＜0.05),IPSS(5.9±2.02 vs 30±1.15,P＜0.05)and QOL score(1.3±0.95 vs 5.2±0.79,P＜0.05)compared with the baseline.Cystoscopy revealed a wide and flat bladder neck with good survival and hemody-namics of the bladder flap.All the patients met the criteria for clinical cure at a median follow-up of 13.2 months.Conclusion:Extraper-itoneal robot-assisted LMYVP provides a new strategy for urinary tract reconstruction in the management of refractory BNC,with the ad-vantages of minimal invasiveness,high efficiency and high success rate.

AIM:To investigate the optimal time of blood collection and the best concentration of Ganlong capsule(GLC)-containing serum for steatohepatitis.METHODS:Sixty C57BL/6J mice were gavaged with GLC at a dose of 90 mg/kg body weight,twice a day for 7 days.Control mice were administered the same volume of 0.9%saline.After 0.5,1,2 and 4 h from the last gavage,blood was collected to prepare GLC-containing serum.The LC-MS/MS was used to detect the inosine content of blank and drug-containing serum at different blood collection times to determine the optimal time.Subsequently,NCTC1469 cells stimulated with palmitic acid(PA)were treated with different concentrations of the GLC-containing serum.Nile Red staining was used to detect lipid droplet formation,and RT-qPCR was employed to as-sess the expression of intracellular fatty acid synthesis(Fabp1,Scd1)and fatty acid β-oxidation gene(Pparα).RE-SULTS:(1)LC-MS/MS detection revealed that the inosine concentration peaked 2 h after the last administration.(2)Nile red staining demonstrated that the GLC-containing serum exerted a dose-dependent decreasing trend of lipid droplets in hepatocytes induced by PA.(3)GLC-containing serum significantly downregulated the mRNA expression levels of lipo-genesis-genes(Fabp1 and Scd1)with a dose-dependent decreasing trend in the PA-induced NCTC1469 cells.The mRNA expression of genes associated with fatty acid β-oxidation(Pparα)were upregulated with a dose-dependent increasing trend.CONCLUSION:The 10%GLC-containing serum collected 2 hours after the last administration in mice has the best therapeutic effect for steatohepatitis.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5％were gram-positive and 70.5％were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species(excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi)was 28.3％,76.7％and 77.9％,respectively.Overall,94.0％of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8％of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 94.2％in the isolates from children and 95.7％in the isolates from adults.The resistance rate to carbapenems was lower than 13.1％in most Enterobacterales species except for Klebsiella,21.7％-23.1％of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1％to 13.3％.The prevalence of meropenem-resistant strains decreased from 23.5％in 2019 to 18.0％in 2022 in Pseudomonas aeruginosa,and decreased from 79.0％in 2019 to 72.5％in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.
