ObjectiveTo investigate the effect and underlying mechanism of the Wulao Qisun prescription on pathological new bone formation in ankylosing spondylitis （AS）. MethodsSynovial fibroblasts were isolated from the hip joints of AS patients and observed under a microscope to assess cell morphology. The cells were identified using immunofluorescence staining. The isolated AS fibroblasts were divided into blank group， low drug-containing serum group， medium drug-containing serum group， high drug-containing serum group， and positive drug group. After drug intervention， cell proliferation was measured using the cell counting kit-8 （CCK-8） assay to observe fibroblast growth and determine the optimal intervention time. Alkaline phosphatase （ALP） activity was measured using the alkaline phosphatase assay. Protein expression of osteocalcin （OCN）， osteopontin （OPN）， and runt-related transcription factor 2 （Runx2） was detected by Western blot. The mRNA expression levels of Wnt5a， β-catenin， and Dickkopf-1 （DKK-1） were measured by real-time quantitative polymerase chain reaction （Real-time PCR）. ResultsCompared with the blank group， each drug-containing serum group of Wulao Qisun prescription and the positive drug group inhibited the proliferation of AS fibroblasts and reduced ALP expression （P<0.01）. Compared with the blank group， the low drug-containing serum group of Wulao Qisun prescription downregulated β-catenin mRNA expression （P<0.05）. The medium and high drug-containing serum groups and the positive drug group significantly downregulated Wnt5a and β-catenin mRNA expression （P<0.05， P<0.01）， with the positive drug group showing the most pronounced effect （P<0.01）. The high drug-containing serum group and the positive drug group significantly upregulated DKK-1 mRNA expression （P<0.01）. Compared with the blank group， the low drug-containing serum group of Wulao Qisun prescription inhibited the expression of OPN and Runx2 proteins （P<0.05， P<0.01）， while the medium and high drug-containing serum groups and the positive drug group inhibited the expression of OCN， OPN， and Runx2 proteins （P<0.05， P<0.01）. ConclusionThe Wulao Qisun prescription can inhibit the proliferation and osteogenic differentiation of AS fibroblasts， thereby delaying the formation of pathological new bone in AS. The possible mechanism involves the regulation of Wnt/β-catenin-related gene expression， further inhibiting the transcription of downstream target genes.

Objective:To explore the influencing factors for compliance to colonoscopy screening for colorectal cancer in outpatients.Methods:Patients aged 40-74 years who visited the outpatient gastroenterology department of 7 tertiary hospitals in 7 regions of Xinjiang from January 2022 to June 2022 were enrolled. Recommendations for colonoscopy screening were made according to the patient's medical conditions, and the questionnaire was used to collect information. The Chi-square test was used to compare the differences of compliant and non-compliant patients. Multivariate logistic regression was used to analyze the influencing factors of compliance to colonoscopy screening.Results:A total of 463 valid questionnaires were obtained from 7 centers, in which, 427 outpatients (92.2%) followed the recommendation for colonoscopy screening, and 36 (7.8%) did not. Chi-square test results showed that there were statistically significant differences between the two groups in gender, age, education, subjective cognition of intestinal polyps, personal history of colorectal polyps, family history of colorectal cancer, family history of colorectal polyps, abdominal pain or distension, and defecation habit or stool changes ( P<0.05). The results of multivariate regression analysis showed that the screening compliance of patients aged 40-49 years ( P=0.005, OR=0.141, 95% CI: 0.036-0.549) and 50-59 years ( P=0.039, OR=0.257, 95% CI: 0.071-0.932) was lower than that of patients aged 60-74 years. The screening compliance of patients with high school education ( P=0.011, OR=3.121, 95% CI: 1.304-7.473) and college education or above ( P=0.016, OR=3.544, 95% CI: 1.270-9.890) was higher than those with primary school education and below. Patients with personal history of colorectal polyps ( P=0.015, OR=12.288, 95% CI: 1.629-92.719), family history of colorectal cancer ( P=0.038, OR=8.506, 95% CI: 1.124-64.351) and changes in defecation habit or stool trait ( P=0.039, OR=4.794, 95% CI: 1.085-21.192) also had higher compliance. Conclusion:Age, educational level, personal history of colorectal polyps, and family history of colorectal cancer are related to colonoscopy screening compliance in outpatients of 7 tertiary hospitals in 7 regions of Xinjiang. The independent risk factors affecting compliance to colorectal cancer screening in outpatients are age of 40-59 years, lower educational level, no previous history of polyps or family history of colorectal cancer, and no defecation habit or stool changes.

Ankylosing spondylitis （AS） is an inflammatory autoimmune disease with chronic low back pain as the main clinical manifestation， which mainly affects the axial joints， peripheral joints and various organs. In severe cases， the spine is stiff or deformed， which affects the quality of life and health of patients. The pathogenic factors of AS are complex， which are related to heredity， immunity and intestinal flora. The pathogenesis of AS is not clear yet. Among them， inflammatory reaction， bone destruction and heterotopic ossification are the main pathological features of AS， which play an important role in the disease process of AS. Traditional Chinese medicine has multi-target， multi-channel and multi-component pharmacological effects， which can prevent and treat AS by anti-inflammation， inhibiting bone destruction and preventing heterotopic ossification， and the clinical effect is remarkable， but there is no relevant literature report. Therefore， this review expounds the relationship between inflammatory reaction， bone destruction and heterotopic ossification and the occurrence and development of AS， and summarizes the latest research reports of traditional Chinese medicine in treating AS from anti-inflammatory， inhibiting bone destruction and preventing heterotopic ossification， aiming at providing reference and new ideas and directions for further research on the prevention and treatment of AS by traditional Chinese medicine.

Objective:To investigate the expression of complement C3 in serums and tissues of lung adenocarcinoma patients with brain metastases and the mechanism of complement C3 in inducing epithelial mesenchymal transition (EMT).Methods:The retrospective case-control study, cell experiments and animal experiments were conducted. The serum samples from 20 healthy examinees, 20 advanced lung adenocarcinoma patients without brain metastases and 20 advanced lung adenocarcinoma patients with brain metastases at the First People's Hospital of Yancheng from January 2021 to January 2023 were collected, and the expression of complement C3 in serum samples was detected by immunoturbidimetry. At the same time, lung tissue samples were collected from 10 lung adenocarcinoma patients without brain metastases, and lung tissue and brain tissue samples were collected from 10 lung adenocarcinoma patients with brain metastases in the First People's Hospital of Yancheng. Immunohistochemistry was used to detect the expression of complement C3, C3aR, Kruppel like factor 5 (KLF5), and N-cadherin (N-cad) in the tissue samples. Using lentivirus to construct a human lung adenocarcinoma with brain metastases cell line PC14-C3 with stable overexpression of complement C3, with cells infected with empty vector virus as the control group (PC14-Ctrl). Western blotting was used to detect the expression of complement C3, KLF5, N-cad, and E-cadherin (E-cad) in PC14-C3 and PC14-Ctrl cells, and scratch assay was used to assess cell migration ability. Using the random number table method, 12 BALB/c nude mice were evenly divided into PC14-C3 group and PC14-Ctrl group. PC14-C3 cells and PC14-Ctrl cells were subcutaneously inoculated on the ventral side, and the body mass and tumor volume of the nude mice were recorded. Real-time fluorescence quantitative polymerase chain reaction was used to detect the expression of KLF5, N-cad and E-cad mRNA in various tumor cells and tumor tissues of nude mice.Results:The serum complement C3 levels in healthy individuals, lung adenocarcinoma patients without brain metastases and lung adenocarcinoma patients with brain metastases were (1.14±0.17) g/L, (1.20±0.15) g/L and (1.61±0.21) g/L, respectively. The serum complement C3 level in lung adenocarcinoma patients with brain metastases was higher than that in lung adenocarcinoma patients without brain metastases and healthy individuals, and the differences were statistically significant (both P < 0.001). The results of immunohistochemical testing showed that the proportions of positive expression areas of complement C3, C3aR, KLF5, and N-cad proteins in the lung primary lesions of lung adenocarcinoma patients with brain metastases were higher than those of patients without brain metastases, and the differences were statistically significant (all P < 0.05). The mRNA ( P < 0.05) and protein expression levels of complement C3 in PC14-C3 cells were higher than those in PC14-Ctrl cells, indicating successful transfection. The scratch assay results showed that the migration rate of PC14-Ctrl cells was (37.5±4.1)%, and the migration rate of PC14-C3 cells was (60.4±2.9)%, and the difference was statistically significant ( t = 7.86, P < 0.01). The relative expressions of EMT promoting molecules KLF5 and N-cad mRNA in PC14-C3 cells were higher than those in PC14-Ctrl cells, while the relative expression of EMT inhibiting molecule E-Cad mRNA was lower than that in PC14-Ctrl cells, and the differences were statistically significant (all P < 0.05). On the 26th day of tumor loading, the tumor volume of nude mice in PC14-C3 group was (610±10) mm 3, while that of PC14-Ctrl group was (321±30) mm 3; the body mass of nude mice in PC14-C3 group was lower than that in PC14-Ctrl group [(21.6±0.6) g vs. (23.2±0.6) g], and the differences were statistically significant (both P < 0.05). At the end of the experiment, 5 nude mice died and 1 survived in the PC14-C3 group; 1 nude mouse died and 5 survived in the PC14-Ctrl group. The relative expressions of KLF5 and N-cad mRNA in the tumor tissues of nude mice in PC14-C3 group were higher than those in PC14-Ctrl group, while the relative expression of E-Cad mRNA was lower than that in PC14-Ctrl group, and the differences were statistically significant (all P < 0.05). Conclusions:Lung adenocarcinoma patients with brain metastases have high levels of complement C3 in their serums and primary lesions. Complement C3 may induce EMT and promote the occurrence of lung adenocarcinoma brain metastases by affecting the expressions of KLF5, N-cad and E-cad.

Ankylosing spondylitis(AS)is a chronic inflammatory autoimmune disease characterized by inflammatory back pain.Its pathological features mainly include inflammation,bone destruction,and pathologic new bone formation.The etiology of AS is complex,and it may be related to genetics,infections,the environment,and intestinal flora.Its pathogenesis has not yet been clarified.In recent years,osteoimmunology,as a new theme in the study of inflammatory arthritis,plays an important role in the pathogenesis and development of AS,which was embodied in the inflammatory response and imbalance of bone metabolism.Traditional Chinese medicine(TCM)has the characteristics of multiple pathways,multiple components,multiple targets and multiple levels.TCM can improve the inflammatory response and bone metabolism imbalance of AS by regulating the osteoblasts of the skeletal system and the related factors of the immune system,thus to prevent and control AS.For this reason,the paper summarizes the role of bone immunology in the pathogenesis of AS,and reviews the current status of research on the intervention of TCM in bone immunology for the treatment of AS,with a view to providing certain references for the future clinical application of TCM in the prevention and treatment of AS.

Background:Recurrence after stone removal is common in patients with choledocholithiasis.Recent studies have indicated that dysbiosis in gut microbiota plays an important role in the formation of cholesterol gallstones.Aims:To explore the effect of probiotics supplementation on serum lipopolysaccharide(LPS)and the indicators of bile acid metabolism in patients with a high risk of cholesterol gallstone formation.Methods:Sixty choledocholithiasis patients undergoing ERCP lithotomy were recruited at the First Affiliated Hospital of Shihezi University from June 2021 to June 2023.Bile and stool samples were collected for bacterial culture.Then the patients were randomly allocated into two groups:patients in control group received conventional supportive therapy after calculus removal,while those in probiotics intervention group were given oral bifid triple viable enteric capsule 420 mg,twice a day for 6 months based on conventional therapy.Changes in serum levels of LPS,the cell wall component of Gram-negative bacteria,fibroblast growth factor 19(FGF19),the key molecule in bile acid metabolism,and cholesterol 7α-hydroxylase(CYP7A1),the rate-limiting enzyme of bile acid synthesis,were determined and compared between the two groups.Results:Escherichia coli and Klebsiella pneumoniae were the main pathogens in bile and stool of patients with choledocholithiasis.Six months after ERCP lithotomy,the serum levels of LPS and FGF19 were decreased,and the serum level of CYP7A1 was increased in both groups(all P<0.05),especially in probiotics intervention group(all P<0.05).Conclusions:Oral probiotics supplementation can reduce the serum LPS level and modulate the canonical pathway of enterohepatic circulation of bile acids--farnesoid X receptor(FXR)-FGF19 pathway in high-risk patients of cholesterol gallstone formation.These alterations reduce the cholesterol supersaturation in bile and inhibit the probability of cholesterol gallstone formation.

The generalized anxiety disorder scale-7 (GAD-7) was used to screen anxiety symptoms, and the patient health questionaire-8 (PHQ-8) was performed to screen depression symptoms, and the general situation questionnaire was used to collect clinical information of patients. The questionnairs were completed via the Questionnaire Star platform or paper questionnaire, and a database was established. The patients were divided into groups according to whether with anxiety and depression symptoms. Multivariable logistic regression models was performed to analyze the factors related to anxiety and depression.Results:A total of 516 questionnaires were distributed and collected, among which 9 questionnaires were incomplete and 507 questionnaires were valid, the effective rate of questionnaires was 98.26%. The detection rates of anxiety and depression symptoms in 507 patients with colorectal polyps were 21.50%(109/507) and 19.33%(98/507), respectively. The results of multivariable logistic analysis revealed that female ( OR=3.87, 95% confidence interval (95% CI) 2.30 to 6.51, P<0.001), maximum diameter of polyp ( OR=1.74, 95% CI 1.14 to 2.67, P=0.011), perception of polyps as cancer ( OR=13.96, 95% CI 1.48 to 132.07, P=0.022), and the occurrence of gastrointestinal symptoms after polyp detection ( OR=5.43, 95% CI 1.74 to 16.92, P=0.004) were independent risk factors of anxiety in patients with colorectal polyps. Female ( OR=2.42, 95% CI 1.47 to 4.00, P=0.001), the number of polyps ( OR=1.07, 95% CI 1.01 to 1.13, P=0.028) and the count of gastrointestinal symptoms ( OR=2.04, 95% CI 1.34 to 3.10, P=0.001) were independent risk factors of depression in patients with colorectal polyps. Conclusion:Gender, polyp size, number of polyps, disease perception, and concomitant gastrointestinal symptoms are associated with anxiety and depression in patients with colorectal polyps.

AIM:To explore the effect of tomatidine(TA)on lipopolysaccharide(LPS)-induced nerve cell in-jury and the underlying mechanism.METHODS:The neuroinflammation model was induced by treating SH-SY5Y cells with LPS.These cells were divided into control(CON),LPS,and LPS+TA groups.The LPS group was treated with 5 μg/mL LPS for 24 h to establish an inflammatory model.The LPS+TA group was first treated with 5 μmol/L tomatidine for 24 h and then co-cultured with 5 μg/mL LPS for 24 h.Cell viability was detected using the CCK-8 assay.RT-qPCR was used to detect the mRNA expression of inflammatory factors tumor necrosis factor-α(TNF-α)and interleukin-1β(IL-1β).The protein expression of transcription factor EB(TFEB),p-TFEB,P62,and microtubule-associated protein 1 light chain 3(LC3)expression was detected through Western blot.TFEB localization and cleaved caspase-3 expression were detected through immunofluorescence.The cell apoptosis rate was detected through flow cytometry.RESULTS:(1)Compared with the CON group,the LPS group exhibited significant increases in IL-1β and TNF-α mRNA levels(P＜0.05),the cell apoptosis rate,and the p-TFEB level(P＜0.01).By contrast,P62,LC3-Ⅱ/LC3-Ⅰ,and TFEB protein ex-pression levels decreased significantly(P＜0.05),and TFEB was mainly localized in the cytoplasm.(2)Compared with the LPS group,tomatidine treatment significantly decreased the p-TFEB protein expression level(P＜0.01),increased the TFEB protein expression level(P＜0.01),and promoted the TFEB protein to migrate into the nucleus.After treatment of tomatidine,the LC3-Ⅱ/LC3-Ⅰ protein expression level significantly increased(P＜0.05),and the cell apoptosis rate signifi-cantly decreased(P＜0.01).In addition,the TNF-α mRNA level significantly decreased after tomatidine treatment(P＜0.01).CONCLUSION:Tomatidine improves autophagy dysfunction,inflammatory reaction,and cell apoptosis induced by LPS via activating the transcription factor EB.
