OBJECTIVETo observe the effect of Panax notoginseng saponins (PNS) on serum content of neuronal specific enolase (NSE) and function recovery in patients with cerebral hemorrhage (CH) for exploring the therapeutic action of PNS in treating CH.

METHODSFifty CH patients with their course of disease not more than 5 days were randomly assigned to two groups, 27 in the PNS group and 23 in the control group, all were treated with conventional treatment, while PNS was given additionally to the PNS group. The serum levels of NSE before and after treatment were determined by electrochemiluminescence, and the recovery of patients, including their neuro-function deficit and daily living activity, was assessed according to scoring by the National Institute of Health Stroke Scale (NIHSS) and Barthel Index (BI) respectively.

RESULTSBefore treatment, the difference between the two groups in serum NSE content and scores of NIHSS and BI was insignificant (P > 0.05). However, after 3 weeks of treatment, the level of NSE and score of NIHSS were significantly lower, while score of BI was significantly higher in the PNS group than those in the control group respectively (all P < 0.01). In the PNS group, the level of NSE showed a positive correlation with the score of NIHSS (r = 0.757, P < 0.05), and a negative correlation with the score of BI (r = - 0.803, P < 0.05).

CONCLUSIONPNS can effectively protect the neuron and promote functional rehabilitation in patients after CH.

OBJECTIVETo observe the effect and the possible mechanism of Jiexiao Oral Liquid (JXOL) in preventing and curing virus induced asthma in children.

METHODSOne hundred and sixty patients of acute upper respiratory tract infection (AURTI) with asthma history were randomly divided into 2 groups. JXOL was given to the treated group within 24 hrs after occurrence of AURTI symptoms, and virazole of 10-15 mg.kg-1.d-1 was given to the control group, the therapeutic course for both groups was 7 days. Changes of clinical symptoms, signs, therapeutic effect, pulmonary function and immuno-globulin in patients were observed.

RESULTSThe total effective rate of the treated group was 83.8%, the clinical control rate was 48.8%, while those in the control group were 62.5% and 23.8% respectively, showing significant difference between them (P < 0.01). JXOL could obviously improve the indexes of forced expiratory volume in one second (FEV1) and peak expiratory flow (PEF), reduce the level of IgE, as compared with those before treatment, the difference was significant (P < 0.01 or P < 0.05); it also showed significant difference as compared with those in the control group after treatment. The changes of IgA, IgG and IgM after treatment showed insignificant difference.

CONCLUSIONJXOL was effective in preventing and curing virus induced asthma in children, it also shows pulmonary function improving and immune regulating effects.

To explore effect of autoantibody on identification of ABO and RhD blood group, the blood samples of 38 patients with autoimmune hemolytic anemia (AIHA) were identified by routine typing and typing after chloroquine elution test as well as PCR. The results showed that out of 38 patients with AIHA, 11 cases (31.6%) of ABO blood group were difficulty typed, indirect antiglobulin test were positive, and contradiction between cells typing and sera typing were observed. 1 case of RhD(-) was mistyped as RhD(+) and anti-D was found in its serum. The blood group of these cases were typed correctly by chloroquine elution test. It is concluded that blood group identification of patients with AIHA can be interfered by autoantibody, and the correct typing for blood group of these patients may be determined by using combination of several methods to ensure safe transfusion.

OBJECTIVETo study the association of integrin alpha-2 (ITGA2) gene C807T, integrin beta-3 (ITGB3) gene T176C polymorphisms with ischemic stroke and the effect of the polymorphisms on plasma lipid and lipoprotein levels.

METHODSPolymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and DNA sequencing were used to detect the integrin genotypes in 265 patients with ischemic stroke and 280 healthy controls. The plasma lipid and lipoprotein levels were measured by routine method.

RESULTSPlasma total cholesterol (TC), triacylglycerol (TG) and low density lipoprotein-cholesterol (LDL-C) in the patients with ischemic stroke were significantly higher than those in the controls (P< 0.05). The distributions of the ITGB3 gene T176C polymorphism were not different between the ischemic stroke group and control group, but the ITGA2 gene C807T polymorphism was significantly different. The relative risk suffering from ischemic stroke of the T allele carrier was 1.455 times as that of the C allele carrier (OR=1.455, 95%CI: 1.134-1.866). The level of plasma lipid in the T allele carriers was significantly higher than that in the C allele carriers (P< 0.05).

CONCLUSIONThe ITGA2 gene C807T polymorphism was associated with ischemic stroke, the 807 T allele may be a genetic risk factor for ischemic stroke. The ITGA2 gene C807T polymorphism may affect ischemic stroke through plasma lipid and lipoprotein levels.

AIMTo investigate the effects of Angelica sinensis on the expression of Flt-1, Flk-1 mRNA after the ischemic brain injury in rats.

METHODSWistar rats randomly divided into two groups: group A rats underwent middle cerebral artery occlusion (MCAO) for 2 hours by suture, group B rats underwent MCAO for 2 hours meanwhile received treatment with Angelica sinensis (5g/kg). At 1 st d, 3 rd d and 7 th d after reperfusion, 36 rats( n = 18 in each group) were assessed by neurological scale and brain tissue was taken to assess the lesion ration with 2, 3, 5-triphenyltetrazolium chloride (TTC) staining. The other rats (n = 3 at different time points in each group) were decapitated at 3 h, 6 h, 12 h , 1 st d, 3 rd d, 7 th d after reperfusion. Quantitative reverse transcription and polymerase chain reaction (RT-PCR) technique was used to examine the gene expression of Flt-1, Flk-1.

RESULTSThe neurologic deficit score of rats in group B decreased significantly compared with group A at the same time point (P < 0.05). The infarct volume of group A was significant greater than group B at the same time point after reperfusion (P < 0.01). The results of RT-PCR revealed that the gene expression of Flt-1, Flk-1 in the two groups increased from 3 h after reperfusion and reached its peak at the time of 3 rd d after reperfusion, then declined gradually. The gene expression of Flt-1, Flk-1 in the group B was significantly increased than group A at the same time point (P < 0.01). The gene expression of Flk-1 was positive correlated with Flt-1 in two groups (r = 0.957).

CONCLUSIONThe increasing amount of Flt-1, Flk-1 expression was enhanced by Angelica sinensis following transient interruption of cerebral blood flow in rats.

OBJECTIVETo investigate the expression and distribution of intrahepatic CD4+ CD25+ regulatory T cells in immuno-tolerant and immuno-clearance phase of patients with chronic hepatitis B.

METHODSThe expression of FoxP3 was detected in 19 cases of immuno-tolerant phase and 12 cases of immuno-clearance phase by immunohistochemistry. The relation between the intrahepatic expression of FoxP3 and the clinicopathological features were analyzed.

RESULTSThe positive signal of FoxP3 is located in nuclear of lymphocyte and mainly aggregated in portal areas as well as occasionally scattered in hepatic sinusoids. The expression of intrahepatic FoxP3 in the group of immuno-tolerant phase was significantly increased than those in normal control (P < 0.01), and greatly decreased than those in immuno-clearance phase (P < 0.01). No correlation was observed among the expression of intrahepatic FoxP3, ALT, levels of HBV DNA, HBeAg positive, in patients of immuno-clearance phase, respectively. There were significant differences between immuno-tolerant phase and immuno-clearance phase age, ALT, TBIL, PTA, HBV-DNA and detection of HBeAg but not in sex and family history of HBV infection.

CONCLUSIONCD4+ CD25+ regulatory T cells may play important roles in the clearance of HBV as well as in liver inflammation and injury during chronic HBV infection.

OBJECTIVETo sum up one-stage complete correction of infantile aortic coarctation (CoA) or interrupted aortic arch (IAA) associated with intracardiac anomalies through median sternotomy.

METHODSThe clinical data of 52 infants with CoA or IAA associated with intracardiac anomalies from May 2004 to March 2010 was analyzed. There were 32 male and 20 female, aged from 25 d to 7 months with a mean of (2.03 ± 0.15) months, weighted from 2.5 to 8.0 kg with a mean of (3.9 ± 0.5) kg. All of intracardiac defect were corrected by self-arcula cordisand. Forty cases with CoA were underwent by operative techniques, including resection with end to side anastomosis, extended end to side anastomosis (n = 34), and vertical incision and cross joint (n = 3). Three cases of pseudo-CoA were cut and ductus arteriosus or ligamentum arteriosus and dissected arch. Twelve cases of IAA were underwent by extended end to side anastomosis.

RESULTSThe time of cardiopulmonary bypass was (98 ± 41) min, and all patients hemorrhaged (78 ± 13) ml during operation. One case of IAA associated with double outlet right ventricle died after 43 d post-operation because of left bronchial stenosis. The other patients were in good condition. The rate of aneurysm formation was 11% in 1 to 6 years' follow-up.

CONCLUSIONSOne-stage complete correction of infantile CoA or IAA associated with intracardiac anomalies through median sternotomy yields excellent intermediate surgical results. This operative approach is beneficial, not only with shorten period of therapy and loss operative cost.

New Chemical Entities (NCEs) development is a systematic long-term project that involves multiple disciplines. The translation research will help to build an advanced R&D system from the basic laboratory research, preclinical studies and clinical evaluation to clinical application of drug, for the purpose of shortening the R&D cycle and accelerate the launch of new drugs. In new drug R&D and its clinical application, drug disposition (absorption, distribution, metabolism, excretion, ADME) properties are important criteria for assessing drug-likeness of candidates. ADME evaluation of NCEs plays an important role in the translation research throughout innovative drug R&D process. Therefore, ADME evaluation at the early stage of drug design and development will be helpful to improve the success rate and reduce costs, and further access to safe, effective drugs.
