Analysis on 158 detainees with adverse reactions due to anti-infective drugs / 药学实践杂志

Objective To analyze the characteristics and trends of adverse drug reactions (ADR) induced by anti-infective drugs in Shanghai Prison General Hospital and provide a guideline of rational drug use and pharmacovigilance for detainees. Methods The anti-infective drug induced ADR cases reported to the national ADR monitoring center in our hospital from January 2011 to October 2018 were collected. The primary and secondary factors of types, organs and (or) systems affected by anti-infective drugs that lead to ADR were studied with Pareto diagram. Results 158 ADR cases caused by anti-infective drugs were collected. 143 cases (90.51%) were male in 20-59 years old. Pareto diagram analysis showed that ADRs mainly involved eight kinds of anti-infective drugs (antituberculosis drugs, cephalosporins, sulfonamides, antiviral drugs, penicillin, aminoglycosides, fluoroquinolones and nitroimidazoles). ADRs mainly involved in hepatobiliary and blood system. Both topical and systemic reactions were reported. Abnormal liver function, liver injury, rash and allergic reaction were the most common. Conclusion Pareto diagram method reflected the "critical minority and minor majority" analysis on detainees with ADRs caused by anti-infective drug. It was recommended to focus on anti-tuberculosis drugs and cephalosporin drugs to reduce or avoid the occurrence of ADR.

[Progress in early pancreas development and reprogramming of terminally differentiated cells into ß cells].

Type 1 diabetes mellitus (T1DM) is an autoimmune disease in which the immune system attacks insulin-secreting ß cells, thus leading to an absolute deficiency of insulin. Patients must rely on exogenous insulin, which cannot effectively prevent diabetes complications. Generation of insulin-secreting cells by reprogramming of pluripotent stem cells or somatic cells is a potential approach for the treatment of T1DM. These cells can be used for cell therapy and drug screening, and may eventually provide a cure for the disease. Significant progress has been made in generating insulin-secreting cells through the expression of ß cell specific transcription factors in stem cells or somatic cells. In this review, we summarize recent research progress in early pancreas development, ß cell specific transcription factors and reprogramming of terminally differentiated cells into ß cells.

Estrogen inhibits the early development of mouse follicles through regulating the expression of Kit ligand.

Estrogen inhibits cyst breakdown and primordial follicle assembling of germ cells, but little is known about the underlying mechanisms. We aimed to analyze the effects of estrogen on the early development of mouse follicles using an in vitro ovary culture system and in vivo injection. Newborn mouse ovarian tissues were cultured in vitro for 2 or 4 days with estrogen of 0 M, 10(-8) M and 10(-4) M, respectively, and neonatal mice were injected with 5mg/kg/day estrogen. We found that the percentages of different-stage follicles significantly varied between the control and estrogen-treated groups. In vitro experiments showed that the unassembled follicles accounted for 70.5±2.7% and the primordial follicles accounted for 29.5±2.7% in the treatment group, but in the control group, ovaries had 61.7±8.4% unassembled follicles. In vivo experiments showed that the percentages of unassembled follicles and primordial follicles were 37.1±5.2% and 51.6±2.4% in the control group, while they were 72.6±5.2% and 25.1±5.5% in the treatment group. Moreover, we analyzed the expression of Kit ligand in mouse ovaries treated by estrogen with real-time PCR and western blot technology, and found that compared with the control group, both mRNA and protein expression levels were decreased in the treatment group (P<0.05). These results indicate that estrogen inhibits the development of mouse ovarian follicles by regulating the expression of Kit ligand.

Influencing factors of porcine spermatozoa binding and internalization exogenous DNA / 中国兽医学报

Sperm-mediated gene transfer (SMGT) is one of the most methods in the transgenic animal research and the efficiency of spermatozoa binding and internalization exogenous DNA after sperm/DNA co-culture is important to a successful SMGT.In this study,the influencing factors of exogenous DNA uptake by spermatozoa were detected using DIG labeled EGFP as exogenous gene.The results demonstrated that porcine spermatozoa could spontaneously take up exogenous DNA which mainly binding occurs on the sub-acrosomal and nuclei region of the sperm head.The rate of spermatozoa binding exogenous DNA increased with the extending action of time.At 37℃ and 39℃,the rate of spermatozoa uptake exogenous DNA would not increase after 60 min incubation,and the similar result was observed on 90 min at 17℃.Binding rates and internalization rates of washed ejaculated sperm cells from the 15 boars varied between 6.57%-35.81% and 2.990%-24.66%,respectively.The binding rate and intemalization rate were mostly inhibited by seminal plasma.The binding rates were significantly increased by liposome and DMSO,respectively.Dead-spermatozoa could bind exogenous DNA,the intermalization process could not be completed.Furthermore,the highest binding rate was found in membrane broken spermatozoa as a result of freeze-thawing and this was independent of the sperm donors.

Cost-Minimization Analysis of 4 Chemotherapeutic Schemes for Advanced Non-small Cell Lung Cancer in Elderly Patients / 中国药房

OBJECTIVE:To investigate the pharmacoeconomic efficacy of four chemotherapeutic schemes for advanced non-small cell lung cancer in elderly patients.METHODS:92 elderly patients with advanced non-small cell lung cancer were randomly divided into four groups:GP,NP,PC,and TP groups.The pharmacoeconomic efficacy of the four groups was analyzed and evaluated retrospectively using the cost-minimization analysis in pharmacoeconomics.RESULTS:The costs of GP,NP,PC,and TP schemes were 10 820.69 yuan,5 864.54 yuan,7 595.57 yuan,and 7 774.64 yuan,respectively(P0.05),respectively.The adverse drug reactions were characterized by different degree of myelosuppression and gastrointestinal reactions,all were cured on symptomatic treatment.CONCLUSION:The cost-minimization analysis showed that NP scheme is the optimal one of the four schemes.
