A set of primers amplified the VP1 gene of foot-and-mouth disease vims (FMDV) was designed and synthesized. A reverse transcription-polymerase chain reaction (RT-PCR) technique detected the RNA of FMDV was established after selecting the best purification method, reagents and reaction conditions. Samples of fresh milk, lymph node, spinal cord, vesicular skin, milk powder, cotton swab, mouse and meat in daughter-house were detected by RT-PCR, positive rates were41.4% (24/58), 13.33% (2/15), 20% (1/5), 100% (1/1), 100% (1/1), 37.5% (12/32), 100% (2/2) and 10% - 70%, respectively. However, positive rate of cockroach detected by RT-PCR was 0. The results showed that the established FMDV RT-PCR technique provided a more sensitive, specific and reliable method for diagnosis and epizootic study of the foot-and-mouth disease.

This study based on twenty 3A grade hospital information system (HIS) database in China, adopt toprescription sequence analysis (PSA) with nested case control study (NCCS) to analysis mainly suspected allergy factor of Shenqi Fuzheng injection (Shenqi Fuzheng). Study design according to start to stop using Shenqi Fuzheng whether using dexamethasone injection will crowd divided into cases group and control group, each case matched 4 controls were selected, two groups according to the ratio of the age and sex matched well. Square test, Fisher exact test, single factor and multiple factor logistic regression were used to analyze data Condition on admission, allergic history, dosage and drug combinations were taken into account in cases of suspected allergic reactions. After analysis in two subgroups we found that the single dose (P = 0.000 2) and the combined use of matrine (P < 0.000 1, OR = 14.312, confidence interval [8.184, 25.029]) had significant effects on the suspected allergic reaction. Study on the existing HIS data and the study method based on screening suspected risk factors for allergic reaction. This study can provide guidance for Shenqi Fuzheng injection safety using in clinical practice, and it can also provides new method for the clinical safety reevaluation of post-marketing Chinese medicine injection.

This study aims to assess if adverse drug reactions (ADRs) to Kudiezi injection are allergic in origin. Hospital information system (HIS) data from 18 hospitals in China were used to carry out a nested case control design study. Included were patients who received dexamethasone for suspected allergic reactions after receiving Kudiezi injection. These were compared with non-allergic reaction people. Single factor logistic regression and multiple factor logistic regression were used to analyze data. Condition on admission, allergic history, dosage, disease status and drug combinations were taken into account in cases of suspected allergic reactions. After analysis in two subgroups we found that the condition on solvents had a significant effect, P values were 0.005 5 and < 0.000 1 on suspected cases of allergic reactions. For the first subgroup analysis, we found using other eight injections at the same time as Kudiezi injection could be risk factors in suspected cases of allergic reactions. For the second subgroup analysis combining using mannitol or fructose could increase risks. Based on this current research, condition on admission as well as the concomitant use of some other drugs may be the risk factors in suspected cases of allergic reactions. However, further research for verification is required. This study can provide guidance for safe clinical practice in using Kudiezi injection.

This paper adopted a series of related analysis methods to comprehensively analyze post-marketing clinical safety data of Shenmai injection from 4,220 cases of SRS and 32,358 cases of multicenter, prospective, registered hospital centralized monitoring in large data background, calculated ADR incidence rate was 0.93 per 1,000, main symptoms of ADR includes chest pain, chills, skin itching, palpitations, fever, nausea, dizziness, vomiting, flushing, numbness, allergic reaction, cyanosis, rash, low back pain, and "breath", "anaphylactoid reaction" and "flush" were the safety warning signals of Shenmai injection. Primary disease for chronic pulmonary heart disease, thyroid disease, and combined with cerebral vascular disease, prior to the injection and continuous use of alprostadil, cyclic adenosine monophosphate, combined with quinolones, penicillins were suspicious influence factors of ADR of Shenmai injection, these promot the clinical safety.

OBJECTIVETo explore a new experimental method for screening of allergens in post-market traditional Chinese medicine injections by confirming allergens in Huachansu injection.
METHODFirst of all, the serum of patients allergic to Huachansu injection were collected, at the same time, the dubious allergen was conjugated to bovine serum albumin (BSA) by EDC coupling procedure to form complete antigen (BNP-BSA), which makes it possible to reproduce the allergic reaction of Huachansu injection in vitro. The histamine liberation ratio, the level of TNF-alpha and Histamine released from RBL-2H3 mast cell were detected; the above data were compared with those obtained in vivo.
RESULTThe difference of the histamine liberation ratio, the levels of TNF-alpha and histamine of the resibufogenin-BSA group, group of patients allergic to Huachansu injection were not significant compared with those of normal control group. However, there were significant difference in those data among the cinobufagin-BSA group, the blank control and normal control group (P<0.05).
CONCLUSIONThe allergen in the serum collected from patients allergic to Huachansu injection is resibufogenin.

The paper is to evaluate the efficacy and safety of Shenmai injection for chronic heart failure, retrieving the Pubmed, CBM, CNKI, Wanfang database and VIP database to comprehensively collect all types research report of Shenmai injection for chronic heart failure (CHF). Particularly wishing to point out, randomized controlled trials are include for the evaluation of effectiveness, which are statistically analyzed and evaluated by Rev-Man 5. 2. The current studies show that the improvement rate of NYHA classification of cardiac function of CHF patients and their related indexes figure such as LVEF, SV, CO, BNP, 6 min walking test value are all improved by the combination of Shenmai injection and foundation treatment. However, HR is almost no improvement. Meanwhile, serious ADR/AE of Shenmai injection for CHF isn't appear.

Objective To investigate the effect of protein phosphatase 5 (PP5) on lipid metabolism in the PP5 knockout (KO) mice.Methods Male PP5 KO and wild type (WT) mice at the age of 6 weeks were used in this study. In order to study the effect of high fat diet ( HFD) feeding, the body weight was measured.The liver histology was examined by HE and oil red O staining.To further verify PP5 functions in the adipogenesis, in vitro experiment was carried out using mouse embryonic fibroblasts (MEF).Western blotting and real-time PCR were performed to quantified the expression of lipid metabolism-related genes in the liver tissues.Results Compared with the WT mice, the body weight gain was slower in the KO mice.The size of the lipid droplets was smaller and the quantity was less in the KO mouse liver tissue.In vitro study revealed that the KO mouse MEF cells showed less differentiated adipocytes with smaller lipid droplets than the WT MEF cells.This observation was further confirmed by detecting the expression of adipogenesis-related genes in the HFD liver.The markers of adipocyte differentiation, such as CD36, AP2, PPARγ2, and Glut4, were significantly decreased, while energy expenditure-related markers, such as phosphorylation of GR and expression of UCP1, were significantly increased.Conclusions Protein phosphatase 5 may play a regulatory role in the mouse lipid metabolism through regulating the de-phosphorylation of p-GR and enhancing the expression of UCP1.
