The development of traditional Chinese medicine (TCM) diagnosis and treatment has undergone multiple paradigms, evolving from sporadic experiential practices to systematic approaches in syndrome differentiation and treatment and further integration of disease and syndrome frameworks. TCM is a vital component of the medical system, valued alongside Western medicine. Treatment based on syndrome differentiation embodies both personalized treatment and holistic approaches; however, the inconsistency and lack of stability in syndrome differentiation limit clinical efficacy. The existing integration of diseases and syndromes primarily relies on patchwork and embedded systems, where the full advantages of synergy between Chinese and Western medicine are not fully realized. Recently, driven by the development of diagnosis and treatment concepts and advances in analytical technology, Western medicine has been rapidly transforming from a traditional biological model to a precision medicine model. TCM faces a similar need to progress beyond traditional syndrome differentiation and disease-syndrome integration toward a more precise diagnosis and treatment paradigm. Unlike the micro-level precision trend of Western medicine, precision diagnosis and treatment in TCM is primarily reflected in data-driven applications that incorporate information at various levels, including precise syndrome differentiation, medication, disease management, and efficacy evaluation. The current priority is to accelerate the development of TCM precision diagnosis and treatment technology platforms and advance discipline construction in this area.

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.

Objective:To analyze the efficacy and safety of low-dose azacitidine in the treatment of senile myelodys-plastic syndromes(MDS).Methods:A total of 92 elderly MDS patients who were initially diagnosed in the Huaibei Miners General Hospital and the Affiliated Hospital of Xuzhou Medical University from January 2018 to June 2022 were randomly divided into the observation group and the control group with 46 patients in each group.The observation group received a low dose of azacitidine 100 mg/d,dl-7,28 days as a course of treatment,6 courses in total,and the control group received a standard dose of azacitidine 75 mg(m2·d),d1-7,28 days as a course of treatment,a total of 6 courses of treatment.The clinical efficacy,overall survival(OS)and adverse reactions of the two groups of patients were observed.Results:There was no statistically significant difference in the clinical data between the two groups(P＞0.05).After treatment,the hemoglobin and platelet levels of the two groups of patients were significantly higher than before treatment in each group(P＜0.05).There was no statistically significant difference in leukocyte,hemoglobin and platelet levels between patients in the observation group and control group(P＞0.05).The number of cases with complete remission,partial remission,hematological remission,disease stabilization and disease progression in the observation group were 4,10,22,6 and 4,respectively,with a total effective rate of 78.26％.The numbers of cases with complete remission,partial remission,hematological remission,disease stabilization and disease progression in control group were 8,12,18,4 and 4,respectively,with a total effective rate of 82.61％.The total effective rate of patients in the observation group was slightly lower than that of the control group(x2=0.457,P=0.254).There was no significant difference between the two treatment schemes in the treatment of patients with blood transfusion dependence and patients with low risk,medium risk and high risk(P＞0.05).It takes 4 and 6 courses of treatment to achieve the best treatment response in the control group and observation group respectively.There was no significant difference in OS between the two groups(P＞0.05).In the observation group,there were 4,6 and 2 cases of infection,Ⅲ-Ⅳ degree myelosuppression and gastrointestinal reaction,respectively,with the incidence rate of adverse events being 26.09％.In the control group,there were 6,16 and 6 cases of infection,Ⅲ-Ⅳ degree myelosuppression and gastrointestinal reaction,respectively,with the adverse event rate was 60.87％.The incidence of adverse events in the control group was significantly higher than that in the observation group(x2=7.095,P=0.036).Conclusion:Elderly patients with MDS have poor tolerance to chemotherapy.Reducing azacitidine in the treatment of elderly MDS patients shows good efficacy and safety.

AIM To investigate the clinical effects of Lingxian Tongluo Capsules combined with Wentong Acupuncture Method on patients with lumbar disc herniation.METHODS One hundred and four patients were randomly assigned into control group(52 cases)for 30-day intervention of both Wentong Acupuncture Method and conventional treatment,and observation group(52 cases)for 30-day intervention of Lingxian Tongluo Capsules,Wentong Acupuncture Method and conventional treatment.The changes in clinical effects,TCM syndrome scores,lumbar function indices(ODI index score,JOA score),VAS score,inflammatory factors(TNF-α,IL-1β,IL-6),hemorheological indices(plasma viscosity,whole blood high-shear viscosity,whole blood low-shear viscosity)and incidence of adverse reactions were detected.RESULTS The observation group demonstrated higher total effective rate than the control group(P＜0.05).After the treatment,the two groups displayed decreased TCM syndrome scores,ODI index score,VAS score,inflammatory factors and hemorheological indices(P＜0.05),and increased JOA score(P＜0.05),especially for the observation group(P＜0.05).No significant difference in incidence of adverse reactions was found between the two groups(P＞0.05).CONCLUSION For the patients with lumbar disc herniation,Lingxian Tongluo Capsules combined with Wentong Acupuncture Method can safely and effectively relieve clinical symptoms,promote lumbar function recovery,reduce pain degree,alleviate inflammatory responses,and improve hemorheology.

Objective To investigate the effects of exercise and complex environment on lipopolysaccharide(LPS)-induced dopaminergic neuron death in the substantia nigra of midbrain.Methods C57BL/6 mice were divided into control group,LPS group,LPS+swimming group and LPS+complex environment group,with 7 mice in each group.The mice in the LPS group were injected with LPS into the brain to establish an inflammatory model of Parkinson's disease and lived in cages for 2 weeks.Mice in LPS+swimming group were forced to swim for 15 minutes every day for 2 weeks after modeling.The mice in the LPS+complex environment group were placed in a complex environment for 2 weeks after modeling.The control group mice were not treated.After 14 days of modeling,behavioral experiments such as footprint,open field and rotating rod were performed on each group of mice to detect the autonomous exercise ability,exercise balance ability and depression level of mice.The expressions of tyrosine hydroxylase(TH)in substantia nigra was detected by immunohistochemical staining and Western blotting.The expressions of brain-derived neurotrophic factor(BDNF),Caspase-3,interleukin-1β(IL-1β),interleukin-6(IL-6)and tumor necrosis factor-α(TNF-α)in the substantia nigra of the midbrain were detected by Western blotting.The transcription levels of IL-1β,IL-6 and TNF-α in substantia nigra were detected by RT-PCR.Results Compared with the control group,the exercise ability and balance ability of mice in LPS group,LPS+swimming group and LPS+complex environment group decreased,the depression level increased(P＜0.001),the number of TH positive neurons and BDNF protein decreased significantly(P＜0.001),and the contents of Caspase-3,IL-1β,IL-6 and TNF-α increased significantly(P＜0.001).Compared with the LPS group,the exercise ability and balance ability of the mice in the LPS+swimming group and the LPS+complex environment group were restored,the depression level decreased significantly(P＜0.01),the survival number of TH positive neurons and the content of BDNF increased significantly(P＜0.01),Caspase-3,IL-1β,IL-6 and TNF-α reduced significantly(P＜0.01),and the phenomenon in the LPS+complex environment group was more significant.Conclusion Exercise and complex environment can inhibit LPS-induced central nervous system inflammation in mice,thereby reducing damage to midbrain substantia nigra neurons,and the inhibitory effect of LPS+complex environment group is more significant.

Objective China is among the 30 countries with a high burden of tuberculosis(TB)worldwide,and TB remains a public health concern.Kashgar Prefecture in the southern Xinjiang Autonomous Region is considered as one of the highest TB burden regions in China.However,molecular epidemiological studies of Kashgar are lacking. Methods A population-based retrospective study was conducted using whole-genome sequencing(WGS)to determine the characteristics of drug resistance and the transmission patterns. Results A total of 1,668 isolates collected in 2020 were classified into lineages 2(46.0%),3(27.5%),and 4(26.5%).The drug resistance rates revealed by WGS showed that the top three drugs in terms of the resistance rate were isoniazid(7.4%,124/1,668),streptomycin(6.0%,100/1,668),and rifampicin(3.3%,55/1,668).The rate of rifampicin resistance was 1.8%(23/1,290)in the new cases and 9.4%(32/340)in the previously treated cases.Known resistance mutations were detected more frequently in lineage 2 strains than in lineage 3 or 4 strains,respectively:18.6%vs.8.7 or 9%,P<0.001.The estimated proportion of recent transmissions was 25.9%(432/1,668).Multivariate logistic analyses indicated that sex,age,occupation,lineage,and drug resistance were the risk factors for recent transmission.Despite the low rate of drug resistance,drug-resistant strains had a higher risk of recent transmission than the susceptible strains(adjusted odds ratio,1.414;95%CI,1.023-1.954;P = 0.036).Among all patients with drug-resistant tuberculosis(DR-TB),78.4%(171/218)were attributed to the transmission of DR-TB strains. Conclusion Our results suggest that drug-resistant strains are more transmissible than susceptible strains and that transmission is the major driving force of the current DR-TB epidemic in Kashgar.

Objective:To evaluate the utility of the 9-gene panel as a differential diagnostic method for thyroid nodules within determinate cytological diagnosis and as a parallel diagnostic method for thyroid fine-needle aspiration (FNA) cytology.Methods:579 liquid-based cytology samples from 544 patients were collected after thyroid FNA diagnosis in our hospital from December 2014 to April 2021. Mutations at any site of 9 genes, namely, BRAF, NRAS, HRAS, KRAS, GNAS, RET, TERT, TP53, and PIK3CA as recorded by the Catalogue of Somatic Mutations in Cancer (COSMIC), were analyzed by next-generation sequencing. Taking postoperative histopathology and cytology results with definite benign or malignant diagnosis as the gold standard, the diagnostic efficacy of the 9-gene panel as a reclassified method for thyroid nodules with indeterminate cytological diagnosis and as a parallel diagnostic method for thyroid FNA cytology were evaluated and compared with that of the BRAF V600E single-gene detection method.Results:Of the 579 thyroid nodules, 196 (33.85%) were Bethesda Ⅱ, 11 (1.90%) were Bethesda Ⅲ, 31 (5.35%) were Bethesda Ⅳ, 27 (4.66%) were Bethesda Ⅴ, and 314 (54.23%) were Bethesda Ⅵ, as diagnosed by thyroid FNA cytology. Among these 579 thyroid nodules, 275 were tested positive for 9-gene mutations, with a mutation rate of 47.5%. Of the 329 thyroid nodules surgically removed, 30 (9.12%) were benign, 5 (1.52%) were borderline, and 294 (89.36%) were malignant. Regarding borderline nodules as malignant nodules, the mutation rates of the 9 genes in the 299 malignant thyroid nodules from high to low were BRAF 62.21% (186/299), NRAS 5.02% (15/299), HRAS 1.00% (3/299), PIK3CA 0.67% (2/299), GNAS 0.67% (2/299), KRAS 0.33% (1/299), TP53 0.33% (1/299), TERT 0.33% (1/299) and RET 0.00% (0/299). The malignant risks of the 9 genes from high to low were BRAF 100% (186/186), PIK3CA 100.00% (2/2), GNAS 100.00% (2/2), TERT 100.00% (1/1), TP53 100.00% (1/1), NRAS 78.95% (15/19), HRAS 75.00% (3/4), and KRAS 50.00% (1/2). For thyroid nodules of Bethesda Ⅲ-Ⅳ (indeterminate diagnosis), the sensitivity (SN) of the 9-gene panel in diagnosing thyroid cancer is 34.48% (10/29), the specificity (SP) is 61.54% (8/13), and the accuracy is 42.86% (18/42); whereas the SN of the BRAF V600E detection method is 0%. Therefore, the diagnostic efficiency of the 9-gene panel is significantly better than that of BRAF V600E single gene detection. For thyroid nodules of Bethesda Ⅱ-Ⅵ, the SN of the 9-gene panel in diagnosing thyroid cancer was 68.83% (254/369), the SP was 90.00% (189/210), the accuracy was 76.51% (443/579), and the area under the curve (AUC) was 0.79; whereas the SN of BRAF V600E single-gene detection in diagnosing thyroid cancer was 63.69% (235/369), the SP was 99.52% (209/210), the accuracy was 76.68% (444/579), and the AUC was 0.82. The SP of BRAF V600E detection is higher than that of the 9-gene panel ( P＜0.01), but there is no significant difference in SN, accuracy (both P＞0.05), and AUC ( Z=0.85, P=0.396) between them. Gene mutations indicating poor prognosis were detected in 4 nodules of papillary thyroid carcinoma and 1 nodules of follicular thyroid carcinoma, including 2 nodules with TERT and BRAF V600E co-mutations, 1 nodule with TP53 mutation, and 2 nodules with PIK3CA mutation. Conclusions:As a reclassified method for thyroid lesions with indeterminate cytological diagnosis, the 9-gene panel is better than BRAF V600E single gene detection. As a parallel diagnostic method of thyroid FNA cytology, the 9-gene panel has similar diagnostic efficacy as BRAF V600E single-gene detection. The 9-gene panel can detect individual cases with gene mutations indicating poor prognosis. The identification of patients with these special gene mutations has certain implications for the clinical management of them.

Objective To construct lentiviral vector of p62 gene over-expression,and stably express p62 gene in human monocytic leukemia cells 1(THP-1),and to provide a way to study the role of p62 gene at the cellular lev-el.Methods The p62 gene fragment was amplified by polymerase chain reaction(PCR),and the amplified prod-uct was ligated to the linearized pcDNA3.1-Flag-PCDH10 lentiviral vector.After identifying with PCR,the PCR product was cotransfected with the packaging plasmid into human embryonic kidney cells 293(HEK 293T).THP-1 cells were infected with recombinant lentivirus.Positive cell clones were screened by ampicillin.Western blot and real-time fluorescence quantitative polymerase chain reaction(RT-qPCR)were used to detect THP-1 cell lines with high p62 expression(overexpression group)and THP-1 cell lines transfected with empty plasmid without p62 gene(control group).The expression levels of TNF-α,IL-1β and Cxcl1 after K.p.infection were detected by RT-qPCR.Results The p62 gene fragment was successfully obtained by PCR and ligated to pcDNA3.1-Flag-PCDH10 vector.PCR confirmed that p62-pcDNA3.1-Flag-PCDH10 recombinant plasmid was constructed successfully.Am-picillin-resistant cell lines were selected after lentiviral infection of THP-1 cells.The results of Western blot analysis showed that the THP-1 cells with drug sieve survival increased the expression of P62 protein compared with the con-trol cells(P<0.001),and RT-qPCR analysis showed that the relative mRNA expression of p62 increased(P<0.001).THP-1 cells with high expression of P62 were successfully constructed.The levels of TNF-α、IL-1β and Cxcl1 from THP-1 cells with high expression of P62 significantly increased after infection with K.p.(P<0.01).Conclusion P62-pcDNA3.1-Flag-PCDH10 vector and THP-1 cells with high expression of P62 can be successful-ly constructed by three-plasmid packaging system,which provides a basis for the study of p62.

ObjectiveTo screen optimized protocol of acupuncture for post-prostatectomy urinary incontinence （PPUI） patients， and to provide evidence for clinical practice. MethodsMEDLINE， Embase， Cochrane Library， Web of Science， Chinese Biomedical Literature Database， China National Knowledge Infrastructure， WanFang and VIP databases were searched to collect randomized controlled trials of acupuncture for PPUI. The search was conducted from the establishment of the database to February 1， 2024， and the quality of the literature was evaluated to exclude the studies with a high risk of overall bias or modified Jadad ＜3， and constructed acupuncture protocol and performed meta-analysis. We used International Consultation on Urinary Incontinence Short Form （ICI-Q-SF） scores， quality of life scores， overall effective rate， and modified Jadad scores as beneficial indicators， and the number of acupoints selected， stimulation duration， the number of acupuncture， and the duration of the treatment course as costly indicators， to derive the standardized protocol matrix， and used the entropy method to determine the weights of the different decision-making indicators， and finally combined with the Technique for Order Preference by Similarity to Ideal Solution （TOPSIS） for comprehensive evaluation. ResultsNine studies met the criteria， and the acupuncture treatments involved were constructed as six protocols including electrical acupoint stimulation with low-frequency， electroacupuncture at four acupoints of sacral region， replenishing qi and tonifying kidney acupuncture， body acupuncture plus pelvic floor muscle training， auricular acupuncture， and electroacupuncture plus pelvic floor muscle training. The ICI-Q-SF， number of acupuncture sessions， and total effectiveness rate were given higher weights in the decision-making indexes， while the stimulation duration and the duration of treatment course were given lower weights； the entropy method of TOPSIS was used for the evaluation and proved that the best protocol was the electroacupuncture at four acupoints of sacral region which used continuous-wave electroacupuncture with a frequency of 2 Hz for 60 min each time， and required the needle sensation to radiate to the root of the penis， with the advantages of streamlined selection of acupoints， a significant reduction in ICI-Q-SF， and an increase in the effectiveness rate. ConclusionThe final optimized protocol was electroacupuncture at four acupoints of sacral region， which can provide an evidence-based basis for clinical decision-making and guideline development.
