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.

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.

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.

OBJECTIVETo explore Chinese medical syndrome distribution features of Japanese encephalitis (JE), and to analyze its correlation between syndromes and features of etiologies and pathogeneses.

METHODSRecruited were 277 patients with confirmative diagnosis of JE from Wuhan Medical Treatment Center, Children's Hospital Affiliated to Chongqing Medical University, Fifth People's Hospital of Guiyang City, Hangzhou Sixth People's Hospital, and Chengdu Hospital of Infectious Diseases between July to September 2012. Chinese medical syndrome distribution features were summarized from their general materials and detailed records of clinical data, including medical history, symptoms and signs, tongue fur, and pulse figures.The frequency of symptoms and signs was calculated according to mild, ordinary, severe, extreme severe degrees. The distribution of Chinese medical syndromes was summarized. And its correlation between syndromes and features of etiologies and pathogeneses were analyzed.

RESULTSAfter clustering analysis, Chinese medical syndromes of JE could be categorized as four groups: toxicity accumulation in Fei and Wei syndrome (TAFWS), brain collateral impaired by poison syndrome (BCIPS), depression of toxicity in the pericardium syndrome (DTPS), exhaustion of yin and yang syndrome (EYYS). BCIPS and DTPS were dominated, accounting for 74.0% (205 cases). The main causes covered evil of summer heat [accounting for 92.42% (256/277 cases)], heat [accounting for 87.73% (243/277 cases)], and toxin [accounting for 99.64% (276/277 cases)].

CONCLUSIONSThe four Chinese medical syndrome types of JE met Chinese medical clinical features of encephalitis. It is induced by infestation of dampness-heat, resulting in toxicity accumulation in Fei and Wei, brain collateral impaired by poison, depression of toxicity in the pericardium. Yin fluid and blood is exhausted as time goes by. Qi and yin are impaired to form intermingled deficiency and excess, and finally causing exhaustion of yin and yang.

This study is to elucidate the metabolic pathway of 1,2-[bis (1,2-benzisoselenazolone-3 (2H)-ketone)]-ethane (BBSKE) in rats. Rats were administrated with a single dose of BBSKE 200 mg x kg(-1). The metabolites in rat urine, feces, bile and plasma were identified by LC-MSn analysis. The characterization of fragment ions from LC-MSn chromatography and mass spectrometry was applied to the investigation of structures of metabolites. Three phase I metabolites were detected in rat urine and feces. Two of them were also found in plasma and one existed in bile. These products were derived from oxidized, methylated and S-methylated BBSKE, separately. One phase II glucuronide of BBSKE was also found in bile. Therefore, it is possible that BBSKE was metabolized by oxidization, methylation and glucuronidation.

Objective To investigate teratogenicity on the zebrafish embryo and genetoxicity induced by Sodium Pentachlorophenate (NaPCP),and to provide suggestions for protecting the environmental safety and human health. Methods Zebrafish embryonic development test,p53 gene in zebrafish eggs mutagenicity test,Vicia Faba Micronucleus Test and Ames test were used in the studies.Results The results of zebrafish embryonic development test showed that NaPCP increased embryonic 120 hpf teratogeny rates and 120 hpf death rates and decreased embryonic 120 hpf hatching rates in concentration of 0.5 -2.5 μL/L,with significant teratogenic effect on the embryo.The rates of embryo abnormity increased with the exposure time and concentration.Sequence analysis showed that NaPCP exposure group zebrafish p53 gene had mutated at the concentration of 0.4 μL /L.The base substitution of AAT→AAG at codon 49,ACA→ACG at codon 87 and GCG→GCA at codon 158 were detected by PCR -directed sequencing.This may result in the Asn→Lys of expressed p53 protein.As compared with control group,0.2 mg/L,1.0 mg/L dosage of NaPCP could induce an extremely significant increase in micronucleus frequency of vicia faba root tip cells and had a certain dose -effect relationship.Ames test was negative.Conclusion NaPCP could delay embryonic development and even cause embryonic lethality and induce abnormality in zebrafish.NaPCP had certain genetoxicity.

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.
