Objective To observe the therapeutic effect of multidisciplinary rehabilitation therapy on patients with angina pectoris of coronary heart disease.Methods 86 patients with angina pectoris of coronary heart disease were randomly divided into the rehabilitation group(55 cases)and control group(31 cases).The patients in the rehabilitation group received routine drugs and multidisciplinary rehabilitation(psychotherapy,diet guiding,kinesitherapy,post discharged guiding etc).The patients in the control group received routine drugs for 10～14 days,activities after chest pain dispearance and natural life after discharge.The follow up period was 6 months,recording the changes of cardiac event rate,body mass index,blood lipid(glycerol,cholesterol,low-density lipoprotein).Results The rehabilitation group was significantly superior to that of control group in symptom remission velocity and remission degree(P<0.05).Cardiac event rate of the rehabilitation group was lower than that of the control group significantly within follow up period(P<0.01);body mass index and blood lipid were improve in the two groups,but the rehabilitation group was significantly superior to that of the control group(P<0.05).Conclusion The multidisciplinary rehabilitation therapy can improve clinical symptoms of patients with angina pectoris of coronary heart disease and reduce cardiac event.

The anti-hepatitis B virus (HBV) effects and its mechanisms of the ethanol extracts of Hypericum perforatum L. (EHP) in vitro were explored. HepG2 2.2.15 cells, a stable HBV-producing cell line, were cultured as the model system to observe the anti-HBV effect. The viral antigens of cellular secretion, HBsAg and HBeAg, were determined by enzyme linked immunosorbent assay (ELISA). The quantity of HBV-DNA released in the supernatant was assayed by real-time PCR. In order to understand the mechanisms of the suppression of HBV replication, all HBV promoters (Cp, Xp, S1p, S2p and Fp) with luciferase reporter gene were transfected into HepG2 cells respectively. Then the activities of viral promoters were examined by luciferase reporter assay. It was found EHP effectively suppressed the secretion of HBsAg and HBeAg from HepG2 2.2.15 cells in a dose-dependent manner, as well as the extracellular HBV DNA. And EHP could selectively inhibit the activity of HBV promoter Fp. Our data suggest that EHP exerts anti-HBV effects via inhibition of HBV transcription, which helps to elucidate the mechanism underlying the potential therapeutic value of EHP.

Objective To study the expression and regulation of polycystic ovary syndrome ( PCOS) susceptibility gene Hmga2 in endometrial receptivity and decidualization. Methods Experiments including early pregnancy, delayed implantation and activation, artificial decidualization and ovarian steroid hormone treatment were performed, and Q-PCR and Western blot analyses were applied to explain the role of Hmga2 in endometrial receptivity. Results The Hmga2 ex-pression increased gradually with pregnancy. Its expression at the implantation site was significantly higher than that at the inter-implantation site,in the embryo activation group than in delayed implantation group, and in the artificial decidualiza-tion than the non-decidualization. The expression of Hmga2 was positively correlated with the expression of estrogen and progesterone, and was positively regulated by estrogen and progesterone in vivo. Conclusions Our findings indicate that the expression of Hmga2 is closely related to the embryo implantation process in early pregnancy in mice, is involved in the process of endometrial decidualization, and is influenced by the activated blastocyst and steroid hormones.

OBJECTIVETo investigate the psychosocial status and related factors among university students during severe acute respiratory syndrome (SARS) epidemic in Beijing.

METHODSBy means of stratified cluster sampling, symptom checklist-90 (SCL-90) and questionnaire on general information were applied among 6800 students in three universities in Beijing.

RESULTSThere were 6280 valid questionnaires gathered. In order to control and prevent SARS, strict management was conducted in three universities which providing various social supports. Out of the 6280 students, 460 had SCL-90 positive symptoms with a rate of 7.3%. Risk factors of SCL-90 positive symptom were found as follows: major in arts (OR = 2.00), misconception on the control and prevention of SARS (OR = 1.91), considering measures non-effective (OR = 2.25), and do not believe that SARS can be under control (OR = 3.57). Protective factors of SCL-90 positive symptom would include as: being female (OR = 0.77), being graduate students (OR = 0.38), and being not much influenced on study and daily life during the period of strict management (OR = 0.54).

CONCLUSIONPsychosocial status of students was influenced by their knowledge and attitude on SARS. Various social supports might keep the university students to having a healthy psychosocial status.

OBJECTIVETo observe the influence of chemotherapy on the switching of Th1/Th2 cytokines in stomach cancer patients.

METHODSTh1/Th2 cytokine genes expressed by peripheral blood mononuclear cells of stomach cancer patients before and after chemotherapy were detected by RT-PCR.

RESULTSThe expression of Th2 cytokines was dominant in patients before chemotherapy, and the dominancy became less marked after chemotherapy.

CONCLUSIONThe immune deviation with Th2 predominance in stomach cancer patients has a tendency to become reversed after chemotherapy.

The flavonoids were investigated from the whole plants of Lagopsis supina. The compounds were isolated and purified by various column chromatography, and their structures were identified by physiochemical properties and spectroscopic data. Two flavones were isolated from the CH2Cl2 layer of Lagopsis supina extract and identified as genkwanin (1) and 5-hydroxy-7,4'-dimethoxyflavone (2), respectively.

Antibody-drug conjugate (ADC) is a new class of therapeutics composed of a monoclonal antibody and small cytotoxin moieties conjugated through a chemical linker. ADC molecules bind to the target antigens expressed on the tumor cell surfaces guided by the monoclonal antibody component. The binding ADC molecules can be internalized and subsequently the toxin moieties can be released within the tumor cells via chemical and/or enzymatic reactions to kill the target cells. The conjugation combines the merits of both components, i.e., the high target specificity of the monoclonal antibody and the highly potent cell killing activity of the cytotoxin moieties. However, such complexities make the pharmacokinetic and metabolic studies of ADCs highly challenging. The major challenges should include characterization of absorption, distribution, metabolism and excretion, investigation of underlying mechanisms, assessment of pharmacokinetic- pharmacodynamic relationship, and analytical method development of ADC drugs. This review will discuss common pharmacokinetic issues and considerations, as well as tools and strategies that can be utilized to characterize the pharmacokinetic and metabolic properties of ADCs.

Objective To investigate the influences of Chinese herbal remedies (CHR) with the actions of replenishing qi and nourishing yin, and resolving mass and freeing the collateral vessels on renal nephrin-mRNA and ultrastructure in rats with early diabetes. Methods All SD rats were randomly divided into 6 groups including group 1 (with nephrectomy), group 2 (model), group 3 (with irbesatan), group 4 (with low-dose CHR), group 5 (with mid-dose CHR) and group 6 (with high-dose CHR). The relevant drugs or CHR were given intragastrically to different groups respectively. At the end of 6th week the quantity of 24-hour urine protein (UPro) and kidney function were detected. The pathological changes of renal cortex were observed by using transmission electron microscope (TEM) after HE staining. The expression of nephrin was determined by applying RT-PCR.Results There were pathological changes of diabetic nephropathy observed by the light microscope and TEM in group 2 and 1, which were alleviated in other 4 groups. The quantity of UPro decreased significantly in group 3, 4 and 5 compared with that in group 2 and 6 (P<0.05). The renal function was improved significantly in all treatment groups compared with that in group 2 (P<0.05). In group 3, 4, 5 and 6 the expression of nephrin-mRNA increased significantly compared with that in group 2 (P<0.05).Conclusion CHR with the actions of replenishing qi and nourishing yin, and resolving mass and freeing the collateral vessels have a protective effect on kidney in rats with diabetic nephropathy induced by STZ.
