Objective To identify core targets of hepatocellular carcinoma (HCC) by using bioinformatics and specific algorithms, explore their relationships with immune cells, and investigate the causal relationships between immune cells and HCC through Mendelian randomization. Methods Relevant genes associated with the development of HCC were screened using the GEO and TCGA databases. Immune infiltration analysis was conducted using GSVA and CIBERSORT algorithms. A bidirectional Mendelian randomization analysis was then performed to explore the causal relationships between immune cells and HCC. Results A total of 284 HCC-related genes were identified, with 120 genes recognized within the protein interaction network. Immune infiltration analysis revealed significant correlations between key genes and immune cells. Mendelian randomization results indicated that HLA DR on CD33⁺ HLA DR⁺ CD14dim (OR=1.097, 95%CI: 1.002–1.201, P=0.045, P_Bonferroni=0.091) and CD8 on CD28⁺ CD45RA⁺ CD8⁺ T cell (OR=1.123, 95%CI: 1.027–1.228, P=0.011, P_Bonferroni=0.022) were the risk factors for HCC. Conversely, HLA DR⁺⁺ monocyte absolute count was identified as a protective factor for HCC (OR=0.812, 95%CI: 0.702–0.938, P=0.005, P_Bonferroni=0.139). Conclusion The occurrence and development of liver cancer may be related to CDK1, CCNB1, and CDC20, showing a high degree of correlation with Th2 cells, T helper cells, Th17 cells, and DCs. Mendelian randomization shows that HLA DR on CD33⁺HLA DR⁺ CD14dim and CD8 on CD28⁺CD45RA⁺CD8⁺T cells are associated with an increased risk of HCC. The risk of hepatocellular carcinoma is associated with a decrease in the level of HLA DR⁺⁺monocyte absolute count.

Objective:To analyze the epidemic characteristics of reported tuberculosis incidence in Kashgar from 2015 to 2022, and use the seasonal autoregressive integrated moving average (SARIMA) model to predict the incidence, providing references for the local control of pulmonary tuberculosis.Methods:The reported incidence data of tuberculosis in the Kashgar area of Xinjiang from January 2015 to August 2023 were collected through the"Infectious Disease Monitoring System", a subsystem of the "Chinese Disease Prevention and Control Information System". The epidemic characteristics of reported incidence in this area from 2015 to 2022 were analyzed. Two SARIMA models of monthly reported incidence number and rate were established. The prediction performance of the two models was evaluated using the reported incidence data of tuberculosis from January 2023 to August 2023. The χ2 test was used to analyze population characteristics, and the Cochran-Armitage trend test was used to analyze annual incidence. Results:From 2015 to 2022, 133 972 cases of pulmonary tuberculosis were reported in Kashgar, with a yearly reported incidence rate of 383.64/100 000, showing a rising trend ( TCA=77.03, P<0.001) and then a declining trend ( TCA=176.16, P<0.001). The proportion of pathogenic positive pulmonary tuberculosis had increased yearly ( TCA=132.66, P<0.001). The reported onset time was concentrated from January to June each year, with a peak in April. Yengisar County, Zepu County and Yopurga County had the highest reported incidence rate in Kashgar. The sex ratio of men to women was 1.03∶1, and the reported incidence rate of men was higher than that of women ( χ2=27.04, P<0.001). The reported incidence rate of the group aged 60 years and older was the highest. The patient′s occupation was mainly farmers (84.99%). The average relative errors of the SARIMA ( 1, 1, 2) ( 0, 1, 1) 12 model and SARIMA ( 0, 1, 1)( 0, 1, 1) 12 model in predicting the reported monthly incidence number and rate were 11.67% and -9.81%, respectively. Both models had good prediction accuracy (MAPE=33.55%, MAPE=38.22%). Conclusion:The average reported incidence rate of pulmonary tuberculosis in the Kashgar area shows a rising trend first and then a declining trend. The patients are mainly men and farmers, and attention should be paid to the prevention and control of tuberculosis among the elderly in winter and spring. The SARIMA ( 1, 1, 2) ( 0, 1, 1) 12 model and SARIMA ( 0, 1, 1)( 0, 1, 1) 12 model can fit the trend of reported tuberculosis incidence in the Kashgar area well and have good predictive performance.

Aim To investigate the intracellular up-take and target protein binding characteristics of two Bruton's tyrosine kinase inhibitors(BTKi)with differ-ent selectivities to provide further insights into the mechanisms of drug off-target-related bleeding risk.Methods Ibrutinib(non-selective BTKi)and za-nubrutinib(selective BTKi)were used as study drugs.After incubation of MEC-1 cells and human platelets with drugs,the cellular thermal shift assay(CETSA)was combined with Western blot to obtain the melting curve and isothermal curve to analyze the binding char-acteristics of the two drugs with the target protein BTK.After incubation of MEC-1 cells and human platelets with drugs,the concentrations of the two drugs were detected by liquid chromatography-tandem mass spectrometry(LC-MS/MS)to analyze the intracellular uptake of the two drugs.Results CETSA analysis confirmed that zanubrutinib was more selective for the target protein BTK compared to ibrutinib.LC-MS/MS analysis showed that both drugs were uptaken intracel-lularly by MEC-1 cells and platelets in a concentration-dependent manner.Conclusions While BTKi targe-ting BTK to B lymphocytes exerts therapeutic effects,off-target effects on platelets due to differences in their intracellular uptake,and target-binding characteristics may be one of the reasons for the differences in bleed-ing risk across selective BTKi.

Osteosarcoma （OS） is the most common primary malignant bone tumor originating from mesenchymal stem cells， which features high degree of malignancy， strong invasiveness， easy early metastasis， and high recurrence rate. The clinical manifestations of OS are pain， local mass， limited movement， and pathological fracture. OS mainly occurs in children， adolescents， and the elderly， seriously threatening physical and mental health of patients， as well as their quality of life. The currently available therapies for OS are surgery， chemoradiotherapy， and the combination of the two. Although the therapeutic effect has been improved， tumor recurrence and metastasis and multidrug resistance still occur. Thus， the therapeutic effect is not satisfactory， especially in improving the overall survival rate of patients with metastatic OS. As a result， clinicians and researchers have been making efforts to find an effective therapy. In recent years， the mechanism of curcumin （CUR） against OS has attracted wide attention. CUR， a pigment extracted from the rhizomes or tubers of many plants， such as Curcuma longa， C. rcenyujin， and C. phaeocaulis， has a variety of pharmacological effects. Scholars have found that CUR has the effects of inhibiting proliferation， inducing apoptosis， and reversing multidrug resistance （MDR） of tumor cells， but also it has poor water solubility and low bioavailability， which limit the clinical application. This paper mainly discusses the mechanism of CUR against OS， the existing problems， new treatment methods， and future research directions， which is expected to provide new ideas for scientific researchers and provide a reference for the development and utilization of CUR in the future.

ObjectiveTo analyze and summarize the medication rules of different Pinelliae Rhizoma processed products in the syndrome differentiation and treatment of insomnia using data mining. MethodThe literature on the treatment of insomnia with Pinelliae Rhizoma was retrieved from the China National Knowledge Infrastructure （CNKI）， VIP， and PubMed databases over the past 10 years. An Excel database was constructed to record the prescriptions of different Pinelliae Rhizoma processed products in the treatment of insomnia. SPSS 26.0 software was used for frequency analysis of traditional Chinese medicine （TCM） syndromes related to insomnia， compatibility of drugs， drug effects， and properties. SPSS 26.0 was also used for cluster analysis， factor analysis， and IBM Modeler 18.0 plugin for association rule analysis of the core compatibility of different Pinelliae Rhizoma processed products and combinations. ResultAfter applying inclusion and exclusion criteria， 125 relevant articles were finally included. The commonly used processed products of Pinelliae Rhizoma in the treatment of insomnia were Pinelliae Rhizoma Praeparatum， Pinelliae Rhizoma Praeparatum cum Zingibere et Alumine， and Pinelliae Rhizoma Praeparatum cum Alumine. Among them， Pinelliae Rhizoma Praeparatum was the most frequently used. All three processed products of Pinelliae Rhizoma were often used for insomnia with such TCM syndromes as phlegm-heat disturbing the heart， phlegm-dampness obstructing the interior， and liver Qi stagnation. The compatible drugs were sweet， bitter， and pungent in flavor， cold in nature， and acted on the lung， spleen， heart， and liver meridians， with functions of nourishing deficiency， clearing heat， and calming the mind. The common prescriptions used were Wendantang， Chaihu Longgu Mulitang， Banxia Xiexintang， and Xiaochaihutang， with doses ranging from 6 to 30 g. The core drug combinations were Pinelliae Rhizoma Praeparatum-Poria-Ziziphi Spinosae Semen， Pinelliae Rhizoma Praeparatum Cum Zingibere et Alumine-Jujubae Fructus-Codonopsis Radix， and Pinelliae Rhizoma Praeparatum Cum Alumine-Scutellariae Radix-Bupleuri Radix. ConclusionThis study， for the first time， analyzed and summarized the compatibility and prescription application rules of commonly used processed products of Pinelliae Rhizoma in the treatment of insomnia from the perspective of TCM syndrome differentiation， which provides a theoretical basis for the rational， safe， and effective use of Pinelliae Rhizoma in the treatment of insomnia in TCM.

Claudin18.2(CLDN18.2)is a tight junction protein that is overexpressed in a variety of solid tumors such as gastrointestinal cancer and oesophageal cancer.It has been identified as a promising target and a potential biomarker to diagnose tumor,evaluate efficacy,and determine patient prognosis.TST001 is a recombinant humanized CLDN18.2 antibody that selectively binds to the extracellular loop of human Claudin18.2.In this study,we constructed a solid target radionuclide zirconium-89(89Zr)labled-TST001 to detect the expression of in the human stomach cancer BGC823CLDN18.2 cell lines.The[89Zr]Zr-des-ferrioxamine(DFO)-TST001 showed high radiochemical purity(RCP,＞99％)and specific activity(24.15±1.34 GBq/μmol),and was stable in 5％human serum albumin,and phosphate buffer saline(＞85％RCP at 96 h).The EC50 values of TST001 and DFO-TST001 were as high as 0.413±0.055 and 0.361±0.058 nM(P＞0.05),respectively.The radiotracer had a significantly higher average standard uptake values in CLDN18.2-positive tumors than in CLDN18.2-negative tumors(1.11±0.02 vs.0.49±0.03,P=0.0016)2 days post injection(p.i.).BGC823CLDN18.2 mice models showed high tumor/muscle ratios 96 h p.i.with[89Zr]Zr-DFO-TST001 was much higher than those of the other imaging groups.Immunohistochemistry results showed that BGC823CLDN18.2 tumors were highly positive(+++)for CLDN18.2,while those in the BGC823 group did not express CLDN18.2(-).The results of ex vivo biodistribution studies showed that there was a higher distribution in the BGC823CLDN18.2 tumor bearing mice(2.05±0.16％ID/g)than BGC823 mice(0.69±0.02％ID/g)and blocking group(0.72±0.02％ID/g).A dosimetry estimation study showed that the effective dose of[89Zr]Zr-DFO-TST001 was 0.0705 mSv/MBq,which is within the range of acceptable doses for nuclear medicine research.Taken together,these re-sults suggest that Good Manufacturing Practices produced by this immuno-positron emission tomog-raphy probe can detect CLDN18.2-overexpressing tumors.

Objective: To analyze the epidemiological characteristics of typhus in China from 1950 to 2021, and discuss the challenges in typhus prevention and control in China and suggest future prevention and control strategies. Methods: Based on the reported data of typhus from 1950 to 2021 in China from the Infectious Disease History Database of China Public Health Science Data Center and the National Notifiable Infectious Disease Reporting Information System of Chinese Center for Disease Control and Prevention, we conducted a descriptive statistical analysis. Mann-Kendall test and circular distribution method were used to analyze the incidence, mortality and case fatality of typhus to reveal the temporal, spatial and population distributions and diagnosis of typhus in China. Results: From 1950 to 2021, a total of 452 965 typhus cases and 7 339 typhus deaths were reported in China, with the cases numbers exceeding 10 000 in 14 years of the 1950s, 1960s and 1980s, respectively. Since 1990s, the reported cases and incidence rate of typhus have decreased dramatically and the most cases were sporadic. However, the reported typhus cases in Anhui, Hubei, Hunan Provinces showed significant uptrends. Although typhus could occur all the year round, but the seasonality was observed with the incidence mainly in summer and autumn. For different provinces from the north to the south, the peaks of typhus' monthly incidence tended to shift to earlier dates. The male to female ratio of the cases was 1.01∶1 (18 529∶18 366). However, more cases occurred in women in recent years. The cases aged ≤9 years accounted for the highest proportion (18.9%), but the number of cases aged ≥50 years showed an upward trend. Most cases were farmers with the proportion increasing year by year. Moreover, the cases in students and scattered-living children also accounted for relatively higher proportions. The median of the interval between onset and diagnosis of typhus was 6 days. Most cases were clinically diagnosed, while the proportion of laboratory-confirmed cases was low and most laboratory cases were confirmed by Well-Felix reaction. Conclusions: Although the incidence and mortality of typhus in China has decreased significantly, the risk for local typhus outbreaks still exists. The prevention and control of typhus still face many challenges. It is indispensable to strengthen the pathogen detection and surveillance for typhus in China.
