Aim To explore the effect and mechanism of the artesunate(ART)on hepatocellular carcinoma(HCC).Methods The cell lines MHCC-97H and HCC-LM3 were used to be detected.MTT and clone formation were used to determine the cell proliferation;Wound healing was used to detect the cell migration;Transwell was used to test the cell invasion.Flow-cy-tometry was used to detect cell apoptosis and cell cy-cle.RNA-seq and qRT-PCR was used to detect the genes expression.Results The proliferation,migra-tion and invasion of treated cells were obviously inhibi-ted(P＜0.01).Moreover,the apoptosis rate in-creased significantly,so did the proportion of G2/M cells.Transcriptomic analysis identified GADD45A as a potential target of ART through RNA-sequencing da-ta,and suggested that ART might induce apoptosis and cell cycle arrest through regulating the expression of GADD45A.In addition,the results of mechanism studies and signaling analysis suggested that GADD45A had interaction with its upstream gene NACC1(nucle-us accumbens associated 1).Moreover,after ART treatment,the expressions of GADD45A and NACC1 were changed significantly.Conclusion ART may be a potential drug to resist HCC by affecting the expres-sion of GADD45A and its upstream gene NACC1,which provides a new drug,a new direction and a new method for the clinical treatment of HCC.

Human Respiratory Syncytial Virus (HRSV) is a serious threat to the population health. The elderly are one of the susceptible populations. The prevalence of HRSV in the elderly is generally higher than that in other age groups except children, which has gradually attracted attention in recent years. This paper reviewed the prevalence, common complications and major complications of HRSV in the elderly, briefly expounded the economic burden of HRSV infection, and proposed that attention should be paid to the disease burden of the elderly after HRSV infection, timely treat common complications, so as to reduce the occurrence of adverse survival outcomes and provide scientific evidence for the prevention and control of HRSV infection in the elderly.

With the outbreak of infectious diseases, more and more attention has been paid to surveillance and early warning work. Timely and accurate monitoring data is the basis of infectious diseases prevention and control. Effective early warning methods for infectious diseases can improve the timeliness and sensitivity of early warning work. This paper briefly introduces the intelligent early warning model of infectious diseases, summarizes the emerging surveillance and early warning methods of infectious diseases, and seeks the possibility of diversified surveillance and early warning in different epidemic stages and different outbreak scenarios of infectious diseases. This paper puts forward the idea of constructing a diversified method system of infectious diseases surveillance and early warning based on multi-stages and multi-scenarios and discusses the future development trend of infectious diseases surveillance and early warning, in order to provide reference for improving the construction level of infectious diseases surveillance and early warning system in China.

This study delves into the pivotal factors influencing the consensus process within traditional Chinese medicine guideline development, with the objective of augmenting the quality of this process through methodological recommendations aimed at elevating standardization.

The oral cavity of each person is home to hundreds of bacterial species.While taxa for oral diseases have been studied using culture-based characterization as well as amplicon sequencing,metagenomic and genomic information remains scarce compared to the fecal microbiome.Here,using metagenomic shotgun data for 3346 oral metagenomic samples together with 808 published samples,we obtain 56,213 metagenome-assembled genomes(MAGs),and more than 64％of the 3589 species-level genome bins(SGBs)contain no publicly available genomes.The resulting genome collection is representative of samples around the world and contains many genomes from candi-date phyla radiation(CPR)that lack monoculture.Also,it enables the discovery of new taxa such as a genus Candidatus Bgiplasma within the family Acholeplasmataceae.Large-scale metagenomic data from massive samples also allow the assembly of strains from important oral taxa such as Por-phyromonas and Neisseria.The oral microbes encode genes that could potentially metabolize drugs.Apart from these findings,a strongly male-enriched Campylobacter species was identified.Oral sam-ples would be more user-friendly collected than fecal samples and have the potential for disease diagnosis.Thus,these data lay down a genomic framework for future inquiries of the human oral microbiome.

The vagina contains at least a billion microbial cells,dominated by lactobacilli.Here we perform metagenomic shotgun sequencing on cervical and fecal samples from a cohort of 516 Chinese women of reproductive age,as well as cervical,fecal,and salivary samples from a second cohort of 632 women.Factors such as pregnancy history,delivery history,cesarean section,and breastfeeding were all more important than menstrual cycle in shaping the microbiome,and such information would be necessary before trying to interpret differences between vagino-cervical micro-biome data.Greater proportion of Bifidobacterium breve was seen with older age at sexual debut.The relative abundance of lactobacilli especially Lactobacillus crispatus was negatively associated with pregnancy history.Potential markers for lack of menstrual regularity,heavy flow,dysmenor-rhea,and contraceptives were also identified.Lactobacilli were rare during breastfeeding or post-menopause.Other features such as mood fluctuations and facial speckles could potentially be predicted from the vagino-cervical microbiome.Gut and salivary microbiomes,plasma vitamins,metals,amino acids,and hormones showed associations with the vagino-cervical microbiome.Our results offer an unprecedented glimpse into the microbiota of the female reproductive tract and call for international collaborations to better understand its long-term health impact other than in the settings of infection or pre-term birth.

【Objective】To evaluate the efficacy of ziprasidone injection and the related influencing factors for treating agitation in schizophrenic patients based on published literature in English or Chinese. 【Methods】We searched PubMed， EMBASE， Web of Knowledge， Cochrane Library， Wanfang data， Chinese Journal Full- Text Database（CJFD），Chinese Biomedical Literature Database（CBMdisc）and VIP Chinese Technology Periodical Database（VIP）. The Consolidated Standards of Reporting Trials（CONSORT）statement was used as a criterion for screening and assessing the literature. Meta-analysis and meta-regression were conducted by using STATA. With the effect size as the dependent variable and sex，age，baseline PANSS scale total score and oral antipsychotics as the covariates ，the meta- regression model was analyzed. 【Results】The Grades of Recommendation ，Assessment ，Development and Evaluation（GRADE） approach was employed to rate the overall quality of evidence. A total of 14 studies（5 in English and 9 in Chinese）were included in meta analysis and meta regression. The samples were ，respectively，1 197 and 1 149 at baseline and after treatment. Random effect Meta analysis showed that ziprasidone injection had significant efficacy in the treatment of agitation symptoms［SMD=2.04，95%CI（1.47，2.61），P = 0.000］. Meta regression revealed that the efficacy was related to baseline PANSS scores（t = 5.57 ，P = 0.011）and oral antipsychotics（t = 4.07 ，P = 0.027），but irrelevant to age（t = 0.74，P = 0.539）and language published（t = -0.57，P = 0.625）. The efficacy was better in female patients than that in male patients （t = -2.95 ，P = 0.060）. 【Conclusion】 Ziprasidone injection has significant efficacy in schizophrenia patients with agitation symptoms and the efficacy may be enhanced in those patients with higher baseline PANSS score and added with oral antipsychotics.

OBJECTIVE: To explore the objectivity and time-effect of stimulating effect at acupoint with PGLA in the healthy person, and to provide a basis for the rational interval of minimally invasive embedding of PGLA. METHODS: Before embedding, 8 h, 3rd, 7th, 10th, 14th day after embedding, medical imaging magnetic resonance imaging (MRI) scanning technique was used to collect local T2WI pressure-lowering and T2-Mapping 8 echoes sequence image of left Zusanli (ST 36) in 8 cases of healthy person. The T2-Mapping 8 echoes sequence image was generated by the relevant software to the T2-Mapping image and the local T2 value was measured. The characteristics of local T2WI pressure-fat image signal intensity and the change of T2 value at left Zusanli (ST 36) with minimally invasive embedding with PGLA were observed and analyzed. RESULTS: ①There was no abnormal signal on the T2WI pressure-fat image on the left Zusanli (ST 36) point before the embedding. The high-signal was seen on the local T2WI pressure-fat image at each time point after embedding, there was no significant difference in local signal intensity between 8 h, 3rd and 7th day after embedding. The local signal intensity decreased on the 10th day after embedding, and the local signal intensity decreased significantly on the 14th day after embedding.②The T2 value at each time point after embedding increased significantly compared with that before embedding (all <0.01); there was no significant difference in T2 value among the 8 h, 3rd and 7th day after embedding (all >0.05); there was no significant difference between the T2 value on the 7th and the 10th day after embedding (>0.05)，the T2 value on the 14th day after embedding was significantly lower than that on the 7th day after embedding (<0.01). CONCLUSION It has a stimulating effect on the local acupoints with minimally invasive embedding with PGLA in the healthy person, and the stimulating effect has certain time-effect. The effective stimulation time is about 2 weeks. The rational interval period for the minimally invasive embedding with the PGLA of the same specification type should be about 2 weeks.
