This study aims to evaluate the efficacy of Chinese medicine injections in treating transient ischemic attack(TIA) based on network Meta-analysis. Randomized controlled trial(RCT) about Chinese medicine injections in treating TIA were retrieved from PubMed, Web of Science, Cochrane Library, EMbase, CNKI, VIP, Wanfang, and SinoMed with the time interval from inception to March 1, 2024. The methodological quality of the included articles was assessed by ROB 2.0, and the GRADE system was employed to evaluate the quality of evidence. The gemtc package of R 4.1.2 was used to perform the network Meta-analysis. Finally, 63 RCTs with a total sample size of 5 750 cases were included, involving 11 Chinese medicine injections(Shuxuetong Injection, Danhong Injection, Shuxuening Injection, Ginkgo Damo Injection, Shenxiong Glucose Injection, Ligustrazine Injection, Salviae Miltiorrhizae and Ligustrazine Hydrochloride Injection, Salvianolic Acids for Injection, Dengzhan Xixin Injection, Guhong Injection, and Xueshuantong Injection). All patients received conventional western medicine treatment, and the experimental group was additionally treated with Chinese medicine injection. Network Meta-analysis yielded the following results.(1) In terms of improving the clinical total response rate, 11 Chinese medicine injections combined with conventional western medicine outperformed conventional western medicine alone, and Dengzhan Xixin Injection + conventional western medicine had the best effect.(2) In terms of reducing plasma viscosity, 7 Chinese medicine injections combined with conventional western medicine outperformed conventional western medicine alone, and Shenxiong Glucose Injection + conventional western medicine had the best effect.(3) In terms of reducing whole blood high shear viscosity, 6 Chinese medicine injections combined with conventional western medicine outperformed conventional western medicine alone, and Guhong Injection + conventional western medicine had the best effect.(4) In terms of reducing whole blood low shear viscosity, 6 Chinese medicine injections combined with conventional western medicine outperformed conventional western medicine alone, and Shuxuening Injection + conventional western medicine had the best effect.(5) In terms of reducing fibrinogen, 9 Chinese medicine injections combined with conventional western medicine outperformed conventional western medicine alone, and Ginkgo Damo Injection + conventional western medicine had the best effect.(6) In terms of increasing the average blood flow velocity, 3 Chinese medicine injections combined with conventional western medicine outperformed conventional western medicine alone, and Shuxuening Injection + conventional western medicine had the best effect. In summary, compared with conventional western medicine alone, Chinese medicine injections combined with conventional western medicine were effective in improving the clinical total response rate and the average blood flow velocity, as well as reducing plasma viscosity, whole blood high shear viscosity, whole blood low shear viscosity, and fibrinogen. However, due to the limited quality and quantity of the included articles, the above conclusions need to be verified by more high-quality, multi-center, and large-sample RCT.

The general models for intermediates quality analysis in the production process of Yaobitong capsule were established by near infrared spectroscopy (NIRS) combined with chemometrics, realizing the rapid determination of notoginsenoside R1, ginsenoside Rg1, ginsenoside Re, ginsenoside Rb1, ginsenoside Rd and moisture. The spray-dried fine powder and total mixed granule were selected as research objects. The contents of five saponins were determined by high performance liquid chromatography and the moisture content was determined by drying method. The measured contents were used as reference values. Meanwhile, NIR spectra were collected. After removing abnormal samples by Monte Carlo cross validation (MCCV), Monte Carlo uninformative variables elimination (MC-UVE) and competitive adaptive reweighted sampling (CARS) were used to select feature variables respectively. Based on the feature variables, quantitative models were established by partial least squares regression (PLSR), extreme learning machine (ELM) and ant lion optimization least squares support vector machine (ALO-LSSVM). The results showed that CARS-ALO-LSSVM model had the optimum effect. The correlation coefficients of the six index components were greater than 0.93, and the relative standard errors were controlled within 6%. ALO-LSSVM was more suitable for a large number of samples with rich information, and the prediction effect and stability of the model were significantly improved. The general models with good predicting effect can be used for the rapid quality determination of Yaobitong capsule intermediates.

This study systematically reviewed the randomized controlled trial(RCT) of traditional Chinese medicine(TCM) treatment of post-stroke depression(PSD) and analyzed the clinical study characteristics and outcome indicators, aiming to optimize the design and establish the core outcome set in the future clinical trials of the TCM treatment of PSD. PubMed, Web of Science, Cochrane Library, EMbase, CNKI, VIP, Wanfang, and SinoMed were searched for the relevant RCT published in recent 3 years. The basic characteristics, intervention measures, and outcome indicators of the included RCT were extracted, and the descriptive analysis was carried out. A total of 76 RCTs were eventually included, with the sample size concentrated in 80-100 cases. The most frequent TCM syndromes were liver depression and Qi stagnation(15 times, 31.91%) and phlegm combined with stasis(5 times, 10.63%). The frequency of intervention methods followed a descending trend of TCM decoction(35 times, 46.05%) and TCM decoction + acupuncture(4 times, 5.26%), Chinese patent medicine(3 times, 3.94%), and the intervention mainly lasted for 1 to 3 months(43 times, 60.56%). The adverse reactions of patients were mainly digestive system reaction(150 patients, 39.37%) and nervous system reaction(112 patients, 29.39%). Most of the included studies had unclear risk of bias, involving 84 outcome indicators, which belonged to 8 indicator domains. The RCTs of TCM treatment of PSD showed a variety of problems, such as non-standard TCM syndrome differentiation, inconsistent names of TCM syndrome scores and measurement tools, low quality, unclear risk of bias, neglect of endpoint indicators, unreasonable selection of substitute indicators, lack of differentiation between primary and secondary outcome indicators, non-standard reporting of safety indicators, insufficient attention to economic indicators, and lack of long-term prognosis evaluation. It is suggested that the future research should improve the quality of methodology and build a standardized core outcome set to promote the development of high-quality clinical research in this field.

OBJECTIVE: To investigate the expression of CSF-1 and CSF-1R in the peripheral blood of children with immune thrombocytopenia (ITP) and its clinical significance. METHODS: Forty-four children with ITP treated in our hospital from February 2023 to January 2024 were selected as the observation group, and 40 healthy children were selected as the control group during the same period, and relevant clinical data were collected. Peripheral blood mononuclear cells (PBMC) of children with ITP and healthy children were separated, and the plasma levels of M1 macrophage-associated cytokines (TNF-α, IL-6), M2 macrophage-associated cytokines (IL-10, TGF-β), and CSF-1 were detected by ELISA in the children of both groups. The mRNA levels of M1 macrophage surface markers (CD86, iNOS), M2 macrophage surface markers (CD206, Arg-1) and CSF-1R were detected by RT-PCR in PBMC of children in both groups. Western blot was used to detect the expression of CSF-1R protein in PBMC of the two groups of children. The correlation between platelet count and CSF-1R mRNA expression in PBMC, TNF-α, IL-6, IL-10, TGF-β and CSF-1 in plasma was analyzed. RESULTS: Compared with the control group, the levels of IL-10, TGF-β, CSF-1 and platelet count in plasma of children with ITP were significantly decreased (P < 0.01), and the levels of TNF-α and IL-6 were significantly increased (P < 0.01); the mRNA levels of the M1 macrophage surface markers (CD86, iNOS) in PBMC of children with ITP were significantly increased (P < 0.05), mRNA levels of M2 macrophage surface marker CD206 in PBMC of children with ITP were decreased compared with controls but the difference was not statistically significant ( P >0.05), mRNA levels of Arg-1 were decreased, the difference was statistically significant (P < 0.05). The mRNA and protein levels of CSF-1R in PBMC of ITP children were higher than that in controls. CSF-1R expression in PBMC of ITP was positively correlated with platelet count, IL-10, CSF-1 were positively correlated (r =0.822,0.481,0.405). CONCLUSION CSF-1 is significantly reduced in the plasma of ITP, and CSF-1R mRNA and protein expression is significantly elevated in PBMC of ITP, which are involved in the regulation of macrophage M1/M2 imbalance, and could serve as a potential therapeutic target for ITP.

The traditional detection methods for monitoring the biomass,protein,chlorophyll content and other key indicators in the growth of chlorella have some problems,including complicated operation,slow detection speed and difficult large-scale application.In this study,a fast and efficient monitoring method for the key indicators in the growth of chlorella was established using near infrared spectroscopy and chemometrics.Near-infrared spectroscopy was used to collect near-infrared spectra of chlorella algal fluid at different growth stages,and standard methods were used to detect the biomass,protein and chlorophyll contents of corresponding samples.A quantitative analysis model was established based on partial least squares regression(PLSR).To improve the prediction ability of the model,multiplicative scatter correction(MSC)was used to reduce the interference of scattering on the raw spectrum(RS),standard normal variate(SNV)was used to normalize the original spectral data to eliminate differences between samples,continuous wavelet transform(CWT)was used to obtain the key features of spectral data,the first derivative(1st)was used to enhance the differentiation of the original spectral features,and monte carlo-uninformative variable elimination(MC-UVE)and randomization test(RT)were used to screen the valid variables in the wavelength.By evaluating the prediction ability of different models,the quantitative analysis models of chlorella biomass,protein and chlorophyll content were finally determined.The results showed that the model based on 1st combined with RT spectra had better predictive ability for chlorella nutrient content detection,and the root mean square errors of prediction(RMSEP)and coefficients of determination(R2)were 0.041 and 0.933 for biomass,0.012 and 0.973 for protein,and 0.517 and 0.962 for chlorophyll,respectively.This model showed practical application value,and could realize the rapid and accurate detection of chlorella biomass,protein and chlorophyll content at the same time.

Objective To investigate the effects of a 100 mT static magnetic field(SMF)on emotional behavior and brain damage-related molecules in mice.Methods Fifty-eight C57BL/6N mice were randomly divided into control group(n=25)and observation group(n=33).Mice in observation group were exposed to a 100 mT SMF for 0.5 h/d over 14 consecutive days,while mice in control group underwent pseudo-exposure.On the 7 and 14 days of exposure,anxiety-like behavior was assessed using open field and elevated plus maze tests.Cerebral blood flow was monitored using laser speckle imaging,and the levels of tumor necrosis factor-α(TNF-α),interleukin(IL)-1β,IL-4,central nervous system specific protein β(S100β),neuron-specific enolase(NSE),and brain-derived neurotrophic factor(BDNF)were measured by radioimmunoassay.BDNF expression in the brain was detected by immunofluorescence.Results On the 7 and 14 days of SMF exposure,the open field and elevated plus maze tests showed no statistically significant differences between observation and control groups in the frequencies,durations,and distance entering the central area of the open field and the open arm of the elevated plus maze(P>0.05).Laser speckle imaging revealed no significant difference in cerebral cortical perfusion compared with pre-exposure period(P>0.05).The results of radioimmunoassay showed that compared with control group,on the 7 d of SMF exposure,the serum IL-1β,NSE and S100β levels were significantly increased(P<0.05),the serum BDNF level was significantly decreased(P<0.05),and the IL-1β and TNF-α contents in brain tissues were significantly increased in observation group(P<0.01).On the 14 d of SMF exposure,serum IL-1β,TNF-α,NSE,and S100β levels were significantly increased(P<0.05,P<0.0001),and the brain IL-1β and TNF-α levels were significantly increased(P<0.01)in observation group.No statistically significant differences were found in anti-inflammatory cytokine IL-4 level of serum and brain tissue or BDNF content of brain tissue between the two groups(P>0.05).Conclusion Continuous exposure to a 100 mT SMF for 14 d at 0.5 h/d induces neuroinflammation and brain damage in mice,without inducing anxiety-like behavior.

Objective To investigate the characteristics of changes in hepatitis B surface antigen(HBsAg),hepatitis B virus(HBV)deoxyribonucleic acid(DNA),and alanine aminotransferase(ALT)levels following the cessation of nucleos(t)ide analogues(NAs)therapy in hepatitis B e antigen(HBeAg)-negative chronic hepatitis B(CHB)patients with baseline HBsAg levels<1000 IU/ml.Methods This retrospective cohort study analyzed 73 HBeAg-negative CHB patients treated at the Fifth Medical Centre of Chinese PLA General Hospital from January 2020 to June 2023.Patients were divided into 3 groups according to baseline HBsAg level and discontinuation strategy:HBsAg-negative discontinuation group(n=14),HBsAg-positive discontinuation group(n=25),and HBsAg-positive continuation group(n=34).All patients were followed for 48 weeks.Baseline clinical characteristics and changes in virological and hepatic biochemical indicators during follow-up were compared among the 3 groups.Univariate logistic regression analysis was performed to assess the correlation between clinical indicators and HBV DNA reappearance in HBsAg-positive discontinuation group,and between clinical indicators and HBsAg decline>0.5 log IU/ml in this group.Results There were no significant differences in the baseline levels of gender,age,albumin,and total bilirubin among the 3 groups(P>0.05).The baseline direct bilirubin level was significantly higher in HBsAg-positive discontinuation group than that in other groups(P<0.05),while the lymphocyte counts were significantly higher in HBsAg-negative discontinuation group(P<0.05).During the 48-week follow-up period,the HBV DNA reappearance rate in HBsAg-positive discontinuation group(72.0%)was significantly higher than that in other groups(P<0.001).There was no significant difference in the incidence of ALT elevation among the three groups(P=0.260).The proportion of patients with HBsAg decline>0.5 log IU/ml in HBsAg-positive discontinuation group(24.0%)was significantly higher than that in HBsAg-positive continuation group(5.9%,P<0.05).The proportion of patients with HBsAg increase>0.5 log IU/ml in HBsAg-positive discontinuation group(12.0%)was also significantly higher than that in HBsAg-positive continuation group(0%,P<0.05).Univariate logistic regression analysis revealed no significant association between the analyzed clinical indicators and HBsAg decline(P>0.05).Conclusions Discontinuation of NAs therapy in HBsAg-negative patients demonstrates high safety,with sustained HBsAg negativity post-cessation and low risks of viral relapse and liver function abnormalities.For HBsAg-positive patients,discontinuation may promote HBsAg decline in some individuals but is associated with risks of HBV DNA reappearance and HBsAg elevation.The decision to discontinue therapy should be comprehensively evaluated based on patients'baseline HBsAg levels and clinical characteristics.
