In recent years,researches on drugs concentrated in the ecosystem have become a hot topic. Environmental pharmacology is a new subject studying the source and fate of drugs in the environment. It is found that a lot of pharmaceuticals and pharmaceutically active compounds are released into the environment by the pharmaceutical industry,hospitals and agricultured activities. Drugs in the environment not only affect the ecosystem,which leads to bacterial resistance,but also affect the balance of flora in the biofilm. Furthermore,such drugs may induce epigenetic changes, which may leave to the body vulnerable to diseases. The enrichment of endocrine disruptors can inter?fere with the growth and function of the human reproductive system. China is becoming concerned about environmental drugs. The development of environmental pharmacology can help clarify the interac?tions between drugs and the environment while contributing to public health and food safety in China.

OBJECTIVE:To analyze the relevant factors contributing to ARDs of Co-Salvia Miltiorrhiza injection (CSMI).METHODS:The ARDs of CSMI,reported in domestic literature in recent years,were collected and analyzed.RESULTS:About 7 kinds of clinical manifestation of ARDs were reported,of which,the allergic reaction was the commonest one.CONCLUSION:Clinical physicians should pay attention to the ARDs of CSMI and rationally use the preparation.

Anti-retroviral (ARV) drugs have been successfully used for HIV/AIDS therapy,and their uses in pre-exposure prophylaxis (PrEP) for HIV infection is becoming increasingly important,and is drawing more attentions.Reports on seven large scale,multicentric clinical trials provide significant clinical data for further study and implementation of PrEP.This article reviews the current situation,necessity,questions,problems and prospects of PrEP for HIV infection.

Objective To study the curative effect of gearing lumbar disc herniation with intecverthral disc version operation. Methods 220 patients were randomly recruited into a treatment group (with 120 patients) and a control group (with 100 patients). The treatment group was treated with intervertbral disc version operation, and the control group was treated with epidural injection combined with massage therapy. Evaluate the therapeutic effects at 1 week, three months, and one year after the treatment respectively. Results The therapeutic effect of at 1 week, three months, and one year after the treatment was 83.46%, 86.19%, 93.45% respectively in the treatment group, and 64.68%, 69.08%, 71.04% respectively in the control group. The difference between the two groups was significance. (P<0.05). Conclusion Intervertbral disc version operation was safe and effective in treating lumbar disc herniation.

Fecal microbiota transplantation(FMT)is a method to recover the gut microbiota and treat the intestinal or non-intestinal diseases through transplanting the fecal liquid from healthy population into patients' gastrointestinal tract.There are limited data about the FMT in children.The clinical practice needs professional workgroups,strict indications,normalized and precise procedures.

Most of the transfusion adult outpatients are old people with chronic disease, and theirsmall blood vessels become less elastic with age. They need long course and repeated localised puncture site. On the base of that fact, the author describes the 5.5gauge scalp acupuncture and 7 gauge scalp acupuncture about their use on the patients. The 5.5 gauge scalp acupuncture is smaller and shorter, so it has the advantage of high success ratio and it is easier to be fixed. Additionally, the transfusion speed is easy to be controlled, which reduces the ratios of transfusion reaction and adverse drug reactions. The pinhole is small and can be healed faster. The congestion around the puncture location is less than that of the 7 scalp acupuncture. It can alleviate the pain for patients and increase satisfaction. To sum up, the 5.5 gauge scalp acupuncture should be used widely as we allocate“people oriented”and“All for the patients”.

Objective To explore the combined effects of subchronic exposure of dibutyl phthalate (DBP) and benzo [a] pyrene (B[a]P) on spermatogenesis in male rats. Methods A total of 32 male Sprague-Dawley rats aged 4-5 weeks were randomly divided into 4 groups and treated respectively as follows, corn oil, 1 mg/kg of B[a]P, 50 mg/kg of DBP, 1 mg/kg of B[a]P+50 mg/kg of DBP , the gavage was used every other day, for 90 days. The rats were sacrificed and the testes, epididymis, livers and other visceral organs were collected, and the organ coefficients were calculated. Flow cytometry (FCM) was used to detect changes of cell cycle. The testes were prepared for histological examination, and cauda epididymides were isolated for the determination of progressive motility and density of stored spermatozoa. The blood samples were collected to assess the effect of B[a]P and DBP on plasma testosterone and luteinizing hormone (LH) concentrations with chemiluminescence immumo-assay. Results The percentage of progressively motile stored spermatozoa and stored sperm density were not changed when exposure to B[a]P and DBP. The exposure alone and combined to B[a]P and DBP caused a reduction in mean tubular area compared with the control (P

OBJECTIVE:To analyze the chemical constituents of the essential oil extracted from Mosla chinensis seeds. METHODS: The essential oil was extracted from Mosla chinensis seeds by steam distillation method and identified by GC-MS, and its relative content was determined using normalization method. RESULTS: A total of 20 chromatographic peaks were detected and 17 chemical compounds were identified, which made up 99.06% of the total essential oil content. The major chemical constituents were carvacrol(57.01%), thymol(30.72%), thymol acetate(2.56%), carvacrol acetate(2.14%) and ?-caryophyllene(1.62%). CONCLUSION: The results in our study provides scientific basis for further exploitation and utilization of Mosla chinensis and serves as reference for establishing quality standard of Mosla chinensis herbal medicine.

Objective To study the clinical value of combined detection of serum interleukin(IL)-8 ,tumor necrosis factor(TNF)-α,alvedar cell surface antigen Ⅱ(KL-6) and surface protein D(SP-D) in the diagnosis of idiopathic pulmonary fibrosis(IPF) .Meth-ods Seventy three patients with IPF were selected as the research subjects ,other 73 patients with bacterial pneumonia were taken as the bacterial pneumonia group .The levels of serum IL-8 ,TNF-α,KL-6 and SP-D were detected by enzyme-linked immunosorbent assay (ELISA) .The serum levels of IL-8 ,TNF-α,KL-6 and SP-D were compared between the IPF group and bacterial pneumonia group .The sensitivity and specificity of IPF detection were compared between the 4-index combined detection and single item de-tection .Results The levels of IL-8 ,TNF-α,KL-6 and SP-D in the IPF group were significantly higher than those in the bacterial pneumonia group (P<0 .05) .The positive rate of single detection of four indexes in the IPF group was significantly higher than that in the bacterial pneumonia group (P<0 .05) .The sensitivity and specificity of the 4-index combined detection for diagnosing IPF were 90 .4% and 93 .2% respectively ,which were significantly higher than the those of single index detection (P<0 .05) .Con-clusion The combined detection of IL-8 ,TNF-α,KL-6 and SP-D has better sensitivity and specificity in IPF diagnosis compared with single detection of IL-8 ,TNF-α,KL-6 and SP-D .

Objective To analyse the dynamic changes of cardiac diseases over the past 30 years. Method All hospitalized patients of internal medicine department over the past 30 years in the 2nd Xiangya Hospital of Central South University were analyzed in order to understand the dynamic changes of cardiac diseases. Results The results showed the proportion of the heart diseases to all medical diseases was gradually increased during the past three decades. The constitution ratio of the classification of the heart disease was also changing continuously and progressively, with coronary heart disease ranking the first and, in contrast, rheumatic heart disease the second since 1980s. Meanwhile, the number and the proportion of the patients with cardiomyopathy and arrhythmias of unknown causes were increased. Anemic heart disease and cardiovascular syphilis had been wiped out since 1980s and 1990s respectively. Conclusion Classification of cardiac diseases changes gradually and continually during the past 30 years.
