OBJECTIVE:To investigate the occurrence of ADR induced by Shuxuening injection in Beijing area,and to pro-vide reference for rational drug use in clinic. METHODS:ADR induced by Shuxuening injection in Beijing area during 2003-2013 was classified statistically in respects of population,organs/systems involved in ADR,clinical manifestations,occurrence time, drug combination and prognosis. RESULTS:Of 1648 ADR cases,the incidence of ADR in the elderly patients was higher than young patients,and that of female patients (60.92％) was higher than that of male patients (39.14％). Multiple organs/systems were involved in Shuxuening injection-induced ADR,and top 3 were nervous system (422 cases,21.33％),skin and its appen-dants (411 cases,20.78％) and others (305 cases,15.42％). Clinical manifestations were skin rash,itching,dizziness and ner-vousness,palpitation,arrhythmia,etc. ADR mostly occurred within 5-30 min after medication. In ADR reports,there were a vari-ety of drugs combined with Shuxuening injection. Shuxuening injection combined with Alprostadil injection was most common(61 cases,accounting for 23.46％ of drug combination). Among 1648 ADR cases,there were 622 cured cases and 1039 cases im-proved,4 cases were not improved,3 cases had sequelae and 1 case died. CONCLUSIONS:Clinical application of Shuxuening in-jection should strictly follow the indications of drug package inserts;differentiation of symptoms and signs is based on specific dos-age,solvent,route of administration,etc. It is necessary to strengthen the prescription check,and strengthen the observation after medication especially for the elderly and other special groups so as to reduce and avoid ADR.

50 days),whereas third party skin grafts were vigorously rejected.Conclusion Blockade of CD28-B7 and CD40-CD40 ligand interactions resulted in long-term allograft survival and donor-specific tolerance in mouse cardiac transplantation without chronic rejection.

Objective: To investigate the developmental toxicity of 2,4-dinitrochlorobenzene in zebrafish embryos. Methods: AB wild-type male and female zebrafish were selected to mate and spawn, then the eggs were cultured with Holt buffer solution. Six dose groups ( 0.4, 0.8, 1.0, 1.2, 1.6, 2.0 μg/mL ), a solvent control group and a cosolvent control group, were set up with 20 embryos each. Malformations and death of embryos were observed at 48, 72 and 96 hpf ( hours post fertilization ), the mortality and 50% lethal concentration ( LC50 ) were also calculated. Results: At 48, 72 and 96 hpf, the LC50 of 2,4-dinitrochlorobenzene on zebrafish embryos were 1.668, 1.043 and 0.895 μg/mL, respectively, with a downward trend. After 72 hpf, when the concentration reached 2.0 μg/mL, all the zebrafish died. In the range of 0.4-2.0 μg/mL, the mortality of zebrafish at 48, 72 and 96 hpf increased with the increase of 2,4-dinitrochlorobenzene concentration ( all P<0.05 ); the malformation rate of zebrafish embryos at 48 hpf increased with the increase of 2,4-dinitrochlorobenzene concentration ( P<0.05 ). Zebrafish embryos exposed to 2,4-dinitrochlorobenzene led to yolk sac edema, pericardial edema and spinal curvature. Conclusion 2,4-dinitrochlorobenzene can affect the development of zebrafish embryos, which will lead to lethal and teratogenic effects.

Cell viability of Pichia pastoris was detected by flow cytometry (FCM) with two reagents fluorescein diacetate (FDA) and propidium iodide (PI). Compared with FDA/PI double-stained dot plots and PI single-stained dot plots,the latter could divide dead and living cells into two separate zones,and get the correct proportion. Then PI single-stained method was used to detect the change of cell viability in Pichia patoris fermentation. At glycerol batch and fed-batch phase,little dead cells were detected. At methanol fed-batch phase,cell viability decreased when cell weight increased,and was only 73.8% at 88 h.

We herein reported a 27-year-old woman with a right renal mass for two years. She underwent laparoscopic partial nephrectomy. Immunohistochemical examination of the specimen confirmed the diagnosis of solitary fibrous tumor by revealing its positive staining for cluster of differentiation (CD)34, epithelial membrane antigen (EMA), B-cell lymphoma-2 (Bcl-2) and CD99 in the tumor cells. No adjuvant treatment was carried out. The patient was in good health without local recurrence or metastasis during 2 years of follow-up. Laparoscopic partial nephrectomy for renal solitary fibrous tumor is an alternative treatment to radical nephrectomy. It can provide a good outcome. However, further follow-up and more cases of renal solitary fibrous tumor treated with laparoscopic partial nephrectomy are necessary to compare the oncological outcome with radical nephrectomy.

Connexin-43 (Cx43) expression in prostate cancer (PCa) cells and the potency of gap junctional intercellular communication (GJIC) in the cells were investigated, with an attempt to elucidate the reason why the so-called "bystander effect" mediated by thymidine kinase (TK) suicide gene therapy on PCa cells is not of significance and to explore the role of GJIC in PCa carcinogenesis. mRNA and protein expression of Cx43 in a PCa cell line PC-3m was detected by reverse-transcription polymerase chain reaction (RT-PCR) and strapt-avidin-biotin-enzyme complex (SABC) immunohistochemical staining, and inherent GJIC of PC-3m cells was assayed by scrape-loading and dye transfer (SLDT) assay. The expression of Cx43 in human normal and malignant prostate tissues was determined by SABC immunohistochemistry as well. It was found that Cx43 mRNA and protein expression in PC-3m cells was slightly reduced as compared with positive controls and the location of Cx43 protein was aberrant in cytoplasm rather than on membrane. Assessment of paraffin sections demonstrated that the expression of Cx43 protein in PCa cells was abnormally located and markedly diminished as compared with normal prostatic epithelial ones, displaying a negative correlation to the pathological grade (chi2=4.025, P<0.05). Additionally, capacity of inherent GJIC in PC-3m cells was disrupted, which was semi-quantified as (+) or (-). It was indicated that both down-regulated expression of Cx43 mRNA and aberrant location of Cx43 protein participated in the mechanisms leading to deficient GJIC in PC-3m cells. Lack of efficient GJIC is a molecular event, which may contribute not only to limited extent of "bystander effect", but also to initiation and progression of prostatic neoplasm.

With the advanced development of information technology, there is a huge impact on various industries for the arrival of big data. In the biomedical field, innovative genome sequencing technology enables low-cost, high-throughput, and high-speed to become a reality, which leads to an explosive growth in data and also appeared in an urgent need to process those massive biological information. High performance computing (HPC) along with effective methods is one of the best ways to deal with the problem of big data in biomedical field which could serve the biomedical development best. We discussed the issues faced in biomedical big data processing and concluded that the bioinformatics is an indispensable component of biomedical technologies.

Phytochemical investigation of the roots of Scrophularia buergeriana Miq. (Scrophulariaceae), resulted in the isolation of a new iridoid derivative named as buergerinin (1). Its structure was elucidated as rel-(1R, 5R, 6R)-(2-oxa-bicyclo[3.3.0]oct-7-en-6, 7-diyl)dimethoxypropane based mainly on MS and 1D and 2D NMR spectroscopic analyses.

Objective To investigate the molecular characteristics of human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) patients receiving antiretroviral therapy (ART) in Guizhou Province. Methods Using a convenience sampling strategy, 8 583 samples were collected in Guizhou and an investigation was conducted including face-to-face questionnaire interview and HIV testing. Results 1 511 cases failed in HIV suppression (viral load, VL>1 000 copies/ml). 1 410 cases (93.31%) were successfully genotyped with HIV pol gene, among which 51.42% were genotyped as CRF01_AE, 26.67% as CRF07_BC and 16.1% as CRF08_BC. Conclusion The subtype changes caused by HIV gene mutation should precede the changes of main transmission routes of HIV through the analysis in recent years. Timely monitoring the changes of HIV subtypes can be one of the main bases for the prevention and control of AIDS.
