Osteoporotic vertebral compression fractures(OVCFs)are common orthopedic conditions that can lead to spinal pain and deformity,which greatly affects the quality of life of patients.Currently,there are various treatment methods for OVCFs,but there is still a lack of standards for optimal treatment modalities.Therefore,this article introduces the current treatment methods and character-istics of epidemiology for OVCFs,in order to improve the awareness of this disease among clinicians and provide a reference for select-ing more appropriate treatment regimens.Conservative treatment measures,such as bracing and analgesia,are the basic treatment mea-sures for OVCFs,and anti-osteoporosis drugs play a crucial role in management.Minimally invasive procedures,including percutane-ous vertebroplasty and percutaneous balloon kyphoplasty,remain the primary surgical interventions,and traditional open surgeries are also an important part of treatment,such as anterior spinal fusion,combined anterior and posterior spinal fusion,posterior spinal fusion with three-column osteotomy,and posterior spinal fusion with vertebroplasty.Furthermore,surgeons should focus on the accumulation of related surgical techniques and skills during surgery to effectively address the challenges and complications associated with surgical interventions.Finally,scientific and appropriate treatment methods should be selected for patients,in order to improve long-term treat-ment outcomes and increase the degree of satisfaction among pa-tients.

OBJECTIVE: To investigate the effects of 4-methylcatechol (4MC) on the migration and inflammatory response in rheumatoid arthritis (RA) fibroblast-like synoviocytes (FLS), as well as its underlying mechanisms of action. METHODS: RA-FLS was isolated from synovial tissue donated by RA patients, and the optimal concentration of 4MC was determined by cell counting kit 8 method for subsequent experiments, and the effect of 4MC on the migratory ability of RA-FLS was evaluated via a cell scratch assay. An inflammation model of RA-FLS was induced by tumor necrosis factor α (TNF-α). Real-time fluorescence quantitative PCR and ELISA were employed to detect the gene and protein expression levels of interleukin-1β (IL-1β) and IL-6 in RA-FLS and their culture supernatants, respectively, thereby investigating the anti-inflammatory effects of 4MC. Western blot was used to examine the expressions of nuclear factor κB (NF-κB) signaling pathway-related proteins, including inhibitor of NF-κB-α (IKBα), phosphorylated (P)-IκBα, NF-κB-inducing kinase α (IKKα), P-IKKαβ, P-p65, and p65. Cellular immunofluorescence was utilized to detect the expression and localization of p65 in RA-FLS, exploring whether 4MC exerts its anti-inflammatory effects by regulating the NF-κB signaling pathway. Finally, a collagen-induced arthritis (CIA) mouse model was established. The anti-RA effect of 4MC in vivo was evaluated by gross observation and histological examination. RESULTS: 4MC inhibited RA-FLS migration in a concentration-dependent manner. In the TNF-α-induced RA-FLS inflammation model, 4MC significantly decreased the gene and protein expression levels of IL-1β and IL-6. Furthermore, 4MC markedly reduced the ratios of P-IΚBα/IΚBα, P-IKKαβ/IKKα, and P-p65/p65, thereby blocking the transcriptional activity of p65 by inhibiting its nuclear translocation. This mechanism effectively suppressed the activation of the TNF-α-mediated NF-κB signaling pathway. Animal studies demonstrated that 4MC [10 mg/(kg·day)] significantly lowered serum levels of IL-1β, IL-6, and TNF-α, and alleviated arthritis severity and bone destruction in CIA mice. CONCLUSION 4MC not only inhibits the migration of RA-FLS but also mitigates their inflammatory response by suppressing the NF-κB signaling pathway, thereby effectively exerting its anti-RA effects.

BACKGROUND:Non-alcoholic fatty liver disease is one of the common chronic liver diseases in the world.Aerobic exercise is considered to be an important means for the treatment of non-alcoholic fatty liver disease.However,the mechanism of exercise to improve non-alcoholic fatty liver disease has not been fully clarified.OBJECTIVE:To investigate the effects of aerobic exercise on the protein kinase B/glycogen synthase kinase-3β pathway mediated by Canopy FGF signaling regulator 2(CNPY2)in the liver canopy of non-alcoholic fatty liver disease mice and its mechanism.METHODS:Thirty male CNPY2 knockout mice(ko)and thirty their litters of wild-type mice(wt)were fed adaptively for one week and randomly divided into control group,model group,and model exercise group,with 10 mice in each group.The control group was fed with ordinary diet.The model group and the model exercise group were fed with high-fat diet for 17 weeks.The model exercise group received continuous aerobic exercise intervention from week 10 until the end of the experiment at week 18.Liver histopathology was observed by hematoxylin-eosin and oil red O staining.The levels of serum lipids and liver function were detected by automatic biochemical analyzer.The expression levels of CNPY2,protein kinase B/glycogen synthase kinase-3β pathway,and Caspase-3 protein in liver tissues were detected by Western Blotting.The apoptosis rate of hepatocytes was detected by TUNEL staining.RESULTS AND CONCLUSION:(1)Compared with wt control group,CNPY2 expression in liver tissues of wt model group was increased(P＜0.05),while CNPY2 expression in wt model exercise group was decreased compared with wt model group(P＜0.05).Compared with control group,wt mice and ko mice in model group showed steatosis,increased lipid droplets,abnormal blood lipids and liver function,decreased protein kinase B/glycogen synthase kinase-3β expression(P＜0.05)and increased Caspase-3 expression(P＜0.05),and increased hepatocyte apoptosis rate in liver tissue(P＜0.05).(2)Compared with the model group,wt mice and ko mice showed improvement in the above indexes in model exercise group.(3)Compared with wt mice,the above indexes of ko mice were improved.(4)These findings indicate that CNPY2 gene deletion and aerobic exercise can effectively improve non-alcoholic fatty liver disease.The mechanism may be related to aerobic exercise reducing CNPY2 expression,activating protein kinase B/glycogen synthase kinase-3β signaling pathway,and thus inhibiting hepatocyte apoptosis.

Objective:To evaluate the efficacy and clinical application value of mouse nerve growth factor combined with neostigmine in the treatment of nerve injury in patients bitten by Bungarus multicinctus by a prospective single-blind controlled clinical study.Methods:In June 2020, a prospective, single-blindness, randomized grouping method was used to select patients with bungarus multicinctus saurogobio dabryi subsp. dabryi bite injuries admitted to the Emergency Department of Ganzhou People's Hospital in Jiangxi Province as the study subjects. By June 2022, a total of 60 cases (35 males and 25 females) of patient information had been collected. The patients were divided into two groups <4 h and ≥4 h after being bitten by bungarus multicinctus. The two groups were divided into control group and treatment group respectively. The treatment group was given an intramuscular injection of neostigmine 1mg q8 h and mouse nerve growth factor 18 μg/d based on conventional treatment. The control group was only given conventional treatment. Myasthenia Gravis Composite Scale (MGC) scores were performed for all patients at admission, 4 hours, 8 hours, and 24 hours. Muscle strength was continuously assessed and the recovery time of muscle strength was recorded. Quantitative data comparisons between groups at admission were analyzed using one-way ANOVA, while qualitative data comparisons were conducted using χ2 tests. Variables showing intergroup differences in baseline measurements (Parazacco spilurus subsp. spilurus) were treated as covariates, with treatment outcomes post-admission compared via analysis of covariance (ANCOVA). Pairwise comparisons of quantitative data between groups employed the Bonferroni method. Baseline quantitative data correlation analysis utilized Pearson correlation, followed by partial correlation analysis after controlling for grouping variables.Results:The MGS scores of the treatment group in both the ≥4 h and <4 h patient groups were lower than those of the control group at the same time points ( P<0.05). After adjusting for the influence of MGS scores at admission, the muscle strength recovery time in the ≥4 h treatment group was significantly shorter compared to the control group, with a statistically significant difference ( P<0.001). MGS scores at 4 h, 8 h, and 24 h after admission were positively correlated with muscle strength recovery time ( r=0.540, 0.720, 0.640, respectively, P<0.001). Muscle strength recovery time was positively correlated with disease duration ( r=0.910, P<0.001). Disease duration was positively correlated with MGS scores at admission ( r=0.908, P<0.001) and with muscle strength recovery time ( r=0.757, P<0.001). After controlling for grouping, the correlation coefficient increased, showing a strong correlation ( r=0.892, P<0.001) . Conclusion:The combination of mouse nerve growth factor and neostigmine can shorten the time of muscle weakness after the bite of Bungarus multicinctus, promote the recovery of injured nerves, and improve the clinical symptoms caused by nerve snake venom.

Objective:To explore the application of COVID-19-specific IgG antibody in identifying epidemic Omicron BA.5 strain infection.Method:Omicron BF.7/BA.5 naturally infected population, healthy population vaccinated with the COVID-19 vaccine, and Omicron BF.7/BA.5 breakthrough cases were enrolled into this study. The serum WT-S-IgG and BA.5-S-IgG were detected by indirect ELISA, and the serum-specific IgG antibody levels of different populations were compared. The application value of the two antibody titers and the ratio of the two antibodies in identifying Omicron BA.5 epidemic strain infection were explored by the ROC curve, aiming to provide technical support for pathogen diagnosis.Results:The antibody titers of WT-S-IgG and BA.5-S-IgG in the breakthrough cases were higher than those in the naturally infected population and the healthy population ( P<0.05). The area under the curve (AUC) of WT-S-IgG and BA.5-S-IgG in identifying epidemic Omicron BA.5 strain infection was 0.947 and 0.961, respectively. The AUC of BA.5-S-IgG and WT-S-IgG antibody titer ratio was 0.873. When the antibody titer ratio was 0.855, the sensitivity and specificity were 80.00% and 90.00%, respectively. According to the interval since the last infection, the AUC of the ratio of BA.5-S-IgG to WT-S-IgG antibody titer to identify the infection of epidemic strains less than 30 days and more than 30 days was 0.887 and 0.863, respectively, and the sensitivity and specificity were both above 80%. Conclusion:Both BA.5-S-IgG and WT-S-IgG, as well as the combination of these two antibodies, are of high value in the identification of epidemic strains.

Objective:To investigate the epidemiological characteristics, diagnosis, treat-ment and prognosis of gallbladder cancer in China from 2010 to 2017.Methods:The single disease retrospective registration cohort study was conducted. Based on the concept of the real world study, the clinicopathological data, from multicenter retrospective clinical data database of gallbladder cancer of Chinese Research Group of Gallbladder Cancer (CRGGC), of 6 159 patients with gallbladder cancer who were admitted to 42 hospitals from January 2010 to December 2017 were collected. Observation indicators: (1) case resources; (2) age and sex distribution; (3) diagnosis; (4) surgical treatment and prognosis; (5) multimodality therapy and prognosis. The follow-up data of the 42 hospitals were collected and analyzed by the CRGGC. The main outcome indicator was the overall survival time from date of operation for surgical patients or date of diagnosis for non-surgical patients to the end of outcome event or the last follow-up. Measurement data with normal distribu-tion were represented as Mean±SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M( Q1, Q3) or M(range), and com-parison between groups was conducted using the U test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test. Univariate analysis was performed using the Logistic forced regression model, and variables with P<0.1 in the univariate analysis were included for multivariate analysis. Multivariate analysis was performed using the Logistic stepwise regression model. The life table method was used to calculate survival rates and the Kaplan-Meier method was used to draw survival curves. Log-rank test was used for survival analysis. Results:(1) Case resources: of the 42 hospitals, there were 35 class A of tertiary hospitals and 7 class B of tertiary hospitals, 16 hospitals with high admission of gallbladder cancer and 26 hospitals with low admission of gallbladder cancer, respectively. Geographical distribution of the 42 hospitals: there were 9 hospitals in central China, 5 hospitals in northeast China, 22 hospitals in eastern China and 6 hospitals in western China. Geographical distribution of the 6 159 patients: there were 2 154 cases(34.973%) from central China, 705 cases(11.447%) from northeast China, 1 969 cases(31.969%) from eastern China and 1 331 cases(21.611%) from western China. The total average number of cases undergoing diagnosis and treatment in hospitals of the 6 159 patients was 18.3±4.5 per year, in which the average number of cases undergoing diagnosis and treatment in hospitals of 4 974 patients(80.760%) from hospitals with high admission of gallbladder cancer was 38.8±8.9 per year and the average number of cases undergoing diagnosis and treatment in hospitals of 1 185 patients(19.240%) from hospitals with low admission of gallbladder cancer was 5.7±1.9 per year. (2) Age and sex distribution: the age of 6 159 patients diagnosed as gallbladder cancer was 64(56,71) years, in which the age of 2 247 male patients(36.483%) diagnosed as gallbladder cancer was 64(58,71)years and the age of 3 912 female patients(63.517%) diagnosed as gallbladder cancer was 63(55,71)years. The sex ratio of female to male was 1.74:1. Of 6 159 patients, 3 886 cases(63.095%) were diagnosed as gallbladder cancer at 56 to 75 years old. There was a significant difference on age at diagnosis between male and female patients ( Z=-3.99, P<0.001). (3) Diagnosis: of 6 159 patients, 2 503 cases(40.640%) were initially diagnosed as gallbladder cancer and 3 656 cases(59.360%) were initially diagnosed as non-gallbladder cancer. There were 2 110 patients(34.259%) not undergoing surgical treatment, of which 200 cases(9.479%) were initially diagnosed as gallbladder cancer and 1 910 cases(90.521%) were initially diagnosed as non-gallbladder cancer. There were 4 049 patients(65.741%) undergoing surgical treatment, of which 2 303 cases(56.878%) were initially diagnosed as gallbladder cancer and 1 746 cases(43.122%) were initial diagnosed as non-gallbladder cancer. Of the 1 746 patients who were initially diagnosed as non-gallbladder cancer, there were 774 cases(19.116%) diagnosed as gallbladder cancer during operation and 972 cases(24.006%) diagnosed as gallbladder cancer after operation. Of 6 159 patients, there were 2 521 cases(40.932%), 2 335 cases(37.912%) and 1 114 cases(18.087%) undergoing ultrasound, computed tomography (CT) or magnetic resonance imaging (MRI) examination before initial diagnosis, respec-tively, and there were 3 259 cases(52.914%), 3 172 cases(51.502%) and 4 016 cases(65.205%) undergoing serum carcinoembryonic antigen, CA19-9 or CA125 examination before initially diagnosis, respectively. One patient may underwent multiple examinations. Results of univariate analysis showed that geographical distribution of hospitals (eastern China or western China), age ≥72 years, gallbladder cancer annual admission of hospitals, whether undergoing ultrasound, CT, MRI, serum carcinoembryonic antigen, CA19-9 or CA125 examination before initially diagnosis were related factors influencing initial diagnosis of gallbladder cancer patients ( odds ratio=1.45, 1.98, 0.69, 0.68, 2.43, 0.41, 1.63, 0.41, 0.39, 0.42, 95% confidence interval as 1.21-1.74, 1.64-2.40, 0.59-0.80, 0.60-0.78, 2.19-2.70, 0.37-0.45, 1.43-1.86, 0.37-0.45, 0.35-0.43, 0.38-0.47, P<0.05). Results of multivariate analysis showed that geographical distribution of hospitals (eastern China or western China), sex, age ≥72 years, gallbladder cancer annual admission of hospitals and cases undergoing ultrasound, CT, serum CA19-9 examination before initially diagnosis were indepen-dent influencing factors influencing initial diagnosis of gallbladder cancer patients ( odds ratio=1.36, 1.42, 0.89, 0.67, 1.85, 1.56, 1.57, 0.39, 95% confidence interval as 1.13-1.64, 1.16-1.73, 0.79-0.99, 0.57-0.78, 1.60-2.14, 1.38-1.77, 1.38-1.79, 0.35-0.43, P<0.05). (4) Surgical treatment and prognosis. Of the 4 049 patients undergoing surgical treatment, there were 2 447 cases(60.435%) with complete pathological staging data and follow-up data. Cases with pathological staging as stage 0, stage Ⅰ, stage Ⅱ, stage Ⅲa, stage Ⅲb, stage Ⅳa and stage Ⅳb were 85(3.474%), 201(8.214%), 71(2.902%), 890(36.371%), 382(15.611%), 33(1.348%) and 785(32.080%), respectively. The median follow-up time and median postoperative overall survival time of the 2 447 cases were 55.75 months (95% confidence interval as 52.78-58.35) and 23.46 months (95% confidence interval as 21.23-25.71), respectively. There was a significant difference in the overall survival between cases with pathological staging as stage 0, stage Ⅰ, stage Ⅱ, stage Ⅲa, stage Ⅲb, stage Ⅳa and stage Ⅳb ( χ2=512.47, P<0.001). Of the 4 049 patients undergoing surgical treatment, there were 2 988 cases(73.796%) with resectable tumor, 177 cases(4.371%) with unresectable tumor and 884 cases(21.833%) with tumor unassessable for resectabi-lity. Of the 2 988 cases with resectable tumor, there were 2 036 cases(68.139%) undergoing radical resection, 504 cases(16.867%) undergoing non-radical resection and 448 cases(14.994%) with operation unassessable for curative effect. Of the 2 447 cases with complete pathological staging data and follow-up data who underwent surgical treatment, there were 53 cases(2.166%) with unresectable tumor, 300 cases(12.260%) with resectable tumor and receiving non-radical resection, 1 441 cases(58.888%) with resectable tumor and receiving radical resection, 653 cases(26.686%) with resectable tumor and receiving operation unassessable for curative effect. There were 733 cases not undergoing surgical treatment with complete pathological staging data and follow-up data. There was a significant difference in the overall survival between cases not undergoing surgical treatment, cases undergoing surgical treatment for unresectable tumor, cases undergoing non-radical resection for resectable tumor and cases undergoing radical resection for resectable tumor ( χ2=121.04, P<0.001). (5) Multimodality therapy and prognosis: of 6 159 patients, there were 541 cases(8.784%) under-going postoperative adjuvant chemotherapy and advanced chemotherapy, 76 cases(1.234%) under-going radiotherapy. There were 1 170 advanced gallbladder cancer (pathological staging ≥stage Ⅲa) patients undergoing radical resection, including 126 cases(10.769%) with post-operative adjuvant chemotherapy and 1 044 cases(89.231%) without postoperative adjuvant chemo-therapy. There was no significant difference in the overall survival between cases with post-operative adjuvant chemotherapy and cases without postoperative adjuvant chemotherapy ( χ2=0.23, P=0.629). There were 658 patients with pathological staging as stage Ⅲa who underwent radical resection, including 66 cases(10.030%) with postoperative adjuvant chemotherapy and 592 cases(89.970%) without postoperative adjuvant chemotherapy. There was no significant difference in the overall survival between cases with postoperative adjuvant chemotherapy and cases without postoperative adjuvant chemotherapy ( χ2=0.05, P=0.817). There were 512 patients with pathological staging ≥stage Ⅲb who underwent radical resection, including 60 cases(11.719%) with postoperative adjuvant chemotherapy and 452 cases(88.281%) without postoperative adjuvant chemotherapy. There was no significant difference in the overall survival between cases with postoperative adjuvant chemo-therapy and cases without post-operative adjuvant chemo-therapy ( χ2=1.50, P=0.220). Conclusions:There are more women than men with gallbladder cancer in China and more than half of patients are diagnosed at the age of 56 to 75 years. Cases undergoing ultrasound, CT, serum CA19-9 examination before initial diagnosis are independent influencing factors influencing initial diagnosis of gallbladder cancer patients. Preoperative resectability evaluation can improve the therapy strategy and patient prognosis. Adjuvant chemotherapy for gallbladder cancer is not standardized and in low proportion in China.
