Aim To evaluate the effect of ZST93 on the proliferation in human chronic myeloid leukemia(CML)cells(K562)and explore the possible mechanism.Methods MTT assay, cell growth curve and inverted microscope were used to investigate the effect of ZST93 on proliferation of K562 cells.Cell transfection and Western blot were performed to detect the autophagy, while PI staining, Annexin V-FITC/PI and flow cytometry were conducted to determine cell apoptosis and its anticancer mechanism.Results ZST93 could significantly inhibit the proliferation of K562(IC50=2.59 μmol·L-1)and induce cell cycle arrest at G1-phase in a dose- and time-dependent manner.Also, through leading to accumulation of GFP-LC3, transition into LC3- II from LC3- 1 , and decrease of p62 expression, ZST93 induced autophagy initiation and autophagic flux.Furthermore, ZST93 induced extrinsic apoptotic pathway by activating caspase-8, and further promoted the cleavage of apoptosis related proteins including caspase-9, caspase-3 and PAR P.Moreover, Z-DEYD-FMK, the specific inhibitor of caspase-3 , could dramatically reduce the apoptosis induced by ZST93.Taken together, ZST93 could effec tively inhibit CML cells, arrest eell cycle at G,-phase, induce cell apoptosis anrl initiate autophagy.Conclusions The potential mechanism may he related to the regulation of autophagy intiation/caspase-8/caspase-3 signaling pathway, which provides a new idea and theoretical basis for the treatment of CML.

Gut microbiome sequencing studies have great potential to translate microbial analysis outcomes into human health research. Sequencing strategies of 16S amplicon and whole-metagenome shotgun (WMS) are two main methods in microbiome research with respective advantages. However, how sample heterogeneity, sequencers and library preparation protocols affect the sequencing reproducibility of gut microbiome needs further investigation. This study aims to provide a reference for the selection of sequencing technologies by comparing differences in microbial composition from different sampling sites. The results of three widely adopted sequencers showed that the technical repetition correlation (r= 0. 94) was high in WMS method, while the biological repetition correlation (r = 0. 69) was low. Bray-Curtis distance identified that dissimilarity from biological replicates was larger than that of technical replicates (P<0. 001). In addition, dissimilarity and specific taxonomic profiles were observed between 16S and WMS datasets. Our results imply that homogenization is a necessary step before sample DNA extraction. The sequencers contributed less to taxonomic variation than the library preparation protocols. We developed an empirical Bayes approach that " borrowed information" in calculations and analyzed batch effect parameters using standardized data and prior distributions of (non-) parameters, which may improve population comparability between 16S and WMS and provide a basis for further application to fusion analysis of published 16S and microbial datasets.

OBJECTIVES:
To investigate the protective effects of Shexiang Tongxin Dropping Pill (, STP) on NaSO-induced hypoxia-reoxygenation injury in cardiomyoblast H9c2 cells.
METHODS:
The cell viability and levels of mRNA and protein expression in H9c2 cells were determined following NaSO-induced hypoxia using Hoechst staining, annexin V/propidium iodide (PI) flow cytometry, real-time polymerase chain reaction and Western blot analysis.
RESULTS:
STP pretreatment significantly increased the viability and inhibited aberrant morphological changes in H9c2 cardiomyoblast cells induced by NaSO treatment (P<0.05). In addition, STP pretreatment attenuated NaSO-induced hypoxic damage, down-regulated the expression of pro-apoptotic Bax, and up-regulated the expression of anti-apoptotic Bcl-2 in H9c2 cells (P<0.05).
CONCLUSIONS
STP was strongly cardioprotective in hypoxia-reoxygenation injury by preventing hypoxic damage and inhibiting cellular apoptosis. These results further support the use of STP as an effective drug for the treatment of ischemic heart disease.

Chinese Journal of Practical Pediatrics 2019;34(05):410-413
OBJECTIVE: To investigate the risk factors of purulent meningitis complicated with subdural effusion in infants and young children. METHODS: The clinical data of the infants and young children who were diagnosed with purulent meningitis in PICU of Shengjing Hospital of China Medical University from January 2014 to December 2017 were analyzed retrospectively.All of them were divided into 2 groups according to whether there was complication of subdural effusion. The statistical data were analyzed by SPSS 20.0 software. RESULTS: There were significant differences in hemoglobin,C reactive protein and protein in cerebrospinal fluid between control group and subdural effusion group(P<0.05). Logistic regression analysis showed that hemoglobin(OR=0.940,95%CI:0.899—0.998),C reactive protein(OR=1.015,95%CI:1.004—1.028)and protein in cerebrospinal fluid(OR=2.490,95%CI:1.151—6.315)were independent risk factors for purulent meningitis complicated with subdural effusion(P<0.05). CONCLUSION: Infants and young children diagnosed with purulent meningitis are with lower hemoglobin. Higher C reactive protein and higher protein in cerebrospinal fluid are likely to be complicated with subdural effusion.

Objective:
To explore the effect of the AXL expression on the chemosensitivity of prostate cancer PC-3 and DU145 cells to docetaxel and possible mechanisms.
METHODS:
Using Western blot, we examined the expressions of the AXL protein, p-AXL and Gas6 in the docetaxel-resistant PC-3 (PC-3-DR) and DU145 (DU145-DR) cells stimulated with gradually increased concentrations of docetaxel. We transfected the PC-3 and DU145 cells with negative NC ShRNA and AXL-ShRNA, respectively, which were confirmed to be effective, detected the proliferation, apoptosis and cycle distribution of the cells by CCK8, MTT and flow cytometry after treated with the AXL-inhibitor MP470 and/or docetaxel, and determined the expression of the ABCB1 protein in the PC-3-DR and DU145-DR cells after intervention with the AXL-inhibitor R428 and/or docetaxel.
RESULTS:
The expression of the AXL protein in the PC-3 and DU145 cells was significantly increased after docetaxel treatment (P <0.05). The expressions AXL and p-AXL were remarkably higher (P <0.05) while that of Gas6 markedly lower (P <0.05) in the PC-3 and DU145 than in the PC-3-DR and DU145-DR cells. The inhibitory effect of docetaxel on the proliferation and its enhancing effect on the apoptosis of the PC-3 and DU145 cells were significantly decreased at 48 hours after AXL transfection (P <0.05). MP470 obviously suppressed the growth and promoted the apoptosis of the PC-3-DR and DU145-DR cells, with a higher percentage of the cells in the G2/M phase when combined with docetaxel than used alone (P <0.05). R428 markedly reduced the expression of ABCB1 in the PC-3-DR and DU145-DR cells, even more significantly in combination with docetaxel than used alone (P <0.05).
CONCLUSIONS
The elevated expression of AXL enhances the docetaxel-resistance of PC-3 and DU145 prostate cancer cells and AXL intervention improves their chemosensitivity to docetaxel, which may be associated with the increased cell apoptosis in the G2/M phase and decreased expression of ABCB1.

OBJECTIVETo explore Chinese medical syndrome distribution features of Japanese encephalitis (JE), and to analyze its correlation between syndromes and features of etiologies and pathogeneses.
METHODSRecruited were 277 patients with confirmative diagnosis of JE from Wuhan Medical Treatment Center, Children's Hospital Affiliated to Chongqing Medical University, Fifth People's Hospital of Guiyang City, Hangzhou Sixth People's Hospital, and Chengdu Hospital of Infectious Diseases between July to September 2012. Chinese medical syndrome distribution features were summarized from their general materials and detailed records of clinical data, including medical history, symptoms and signs, tongue fur, and pulse figures.The frequency of symptoms and signs was calculated according to mild, ordinary, severe, extreme severe degrees. The distribution of Chinese medical syndromes was summarized. And its correlation between syndromes and features of etiologies and pathogeneses were analyzed.
RESULTSAfter clustering analysis, Chinese medical syndromes of JE could be categorized as four groups: toxicity accumulation in Fei and Wei syndrome (TAFWS), brain collateral impaired by poison syndrome (BCIPS), depression of toxicity in the pericardium syndrome (DTPS), exhaustion of yin and yang syndrome (EYYS). BCIPS and DTPS were dominated, accounting for 74.0% (205 cases). The main causes covered evil of summer heat [accounting for 92.42% (256/277 cases)], heat [accounting for 87.73% (243/277 cases)], and toxin [accounting for 99.64% (276/277 cases)].
CONCLUSIONSThe four Chinese medical syndrome types of JE met Chinese medical clinical features of encephalitis. It is induced by infestation of dampness-heat, resulting in toxicity accumulation in Fei and Wei, brain collateral impaired by poison, depression of toxicity in the pericardium. Yin fluid and blood is exhausted as time goes by. Qi and yin are impaired to form intermingled deficiency and excess, and finally causing exhaustion of yin and yang.
