Objective To observe effects of aqueous extractive of Clarke boea herb on mice with gastric ulcer, and provide basis for clinical application.Methods Gastric ulcer model was induced by reserpine. The mice were divided into normal group, model group, ranitidine group, low and high dose of Clarke boea herb groups. Mice in treatment groups were given corresponding drugs by gavage, and the normal group and control group were given the same amount of saline for 4 weeks. The area of gastric ulcer, serum proinflammatory cytokines gastric juice volume, gastric juice acidity, iNOS and COX-2 gene expressions were detected.Results Compared with control group, the gastric ulcer area in low and high dose of Clarke boea herb groups decreased significantly. Clarke boea herb increased the SS and VIP, decreased the MOT and SP serum levels (P<0.05,P<0.01). Clarke boea herb reduced the levels of serum proinflammatory cytokines of IL-6, IL-12, TNF-α and IFN-γ(P<0.05,P<0.01). Clarke boea herb also decreased the genetic expressions of iNOS and COX-2 (P<0.05,P<0.01).ConclusionClarke boea herb has good gastric ulcer preventive effects, and the high dose of Clarke boea herb group showed the best efficiency.

Objective To understand human rhinovirus (HRV) etiology of acute lower respiratory tract infection (ALRTI) in children in Shanghai area and establish a nested reverse transcription- polymerase chain reaction (nested RT-PCR) assay.Methods Three hundred and forty-two naso- pharyngeal secretion (NPS) samples from ALRTI cases who were hospitalized were collected during January 2005—December 2005.Nested RT-PCR techniques were used to detect HRV-specific RNA.The PCR products were sequenced and data of nucleotides were analyzed.The proportion of HRV infection in children with ALRTI,the distribution of gender,age and season,and clinical char- acteristics were also investigated.Results Forty-six (13.5%) of 342 samples were HRV positive detected by nested RT-PCR.The sequences of 15 positive samples shared high homology of 83%- 97% with HRV sequence in GenBank.Within the 15 positive samples,nucleotide homology varied from 64.4% to 98.4%,and the ratio of genetic variation was from 1.6% to 48.3%./00.These 15 ampli- cons attribute to the two branches of HRV cladogram.The sequences of 15 amplieons were highly varied,in which single nucleotide mutation and several nearby nueleotides mutations were found. Ribonucleotide deletion and insertion in the nucleotide sequence was also found.HRV positive sam- ples were detected in 33 boys and 13 girls,respectively.The ratio of infection cases between boys and girls was 2.5:1.Of 46 HRV infected cases,27 (58.7%) were less than 12 months of age and 38 (82.6%) were less than 3 years old.HRV infected ALRTI occured all the year round and peaked from March to May.Of the patients whose NPS samples were HRV positive detected by nested RT-PCR,45 patients were diagnosed with bronchopneumonia and 1 was diagnosed with asthmatic bronchitis.Fever of most patients was moderate.The peripheral blood leukocyte counts in thirty-nine (84.8%) patients were less than 10?10~9/L.Neutrophil percentages in thirty-seven (80.4%) patients were less than 0.50.C-reactive protein of thirty-six (78.3%) patients were less than 8 mg/L. All of these features were the characteristics of viral pneumonia.The complications were not common and conditions of most patients were not severe.All the children were cured.Conclusions This nes- ted RT-PCR technique is highly specific,rapid and convenient for the detection of HRV RNA in NPS of patients with ALRTI and the genome of HRV viruses is highly variable.The incidence of HRV infection predominates in children in Shanghai area.ALRTI of HRV is short of specificity and condi- tions of most patients are not severe and their prognoses are fine.

Objective To investigate the effects of silencing Smo gene on proliferation and apoptosis of rat prima-ry chondrocyte in vitro.Methods The primary chondrocyte was obtained by mechanical-enzyme digestion and identified by Immunohistochemical cells ( ColⅡ) .The animals were divided into control group , control siRNA group and Smo siRNA 1 ~3 group.The siRNA was transfected into chondrocytes by lentivirus vector .After 72 h, the cell viability was detected by MTT, Smo expression was detected by RT-PCR and Western blot, and the apoptosis of chondrocyte was assessed by flow cytometry .Results All types of siRNA were transfected into primary chondrocyte by vectors, the Smo siRNA 1 ~3 may inhibit the expression of Smo mRNA and protein in chondrocytes, and Smo siRNA2 had the highest silencing rate ( the expressions of Smo mRNA and protein were 0.19 ±0.03 and 0.39 ±0.07 ) .The cell viability in Smo siRNA2 group was lowest ( 77.38% ±7.19%) , while the apoptosis rate of Smo siRNA2 was highest ( 21.43%±2.97%) .Conclusions Silencing Smo gene in primary chondrocytes may inhibit proliferation and promote apoptosis , Smo may have a protecting role from apop-tosis of the chondrocyte.

Therapeutic hypothermia has been shown to improve neurological outcomes after global ischaemia/hypoxia in patients who have had cardiac arrest. Therapeutic hypothermia is one of the most extensively studied and influential therapeutic strategies of acute ischemic stroke. Previous studies of therapeutic hypothermia mainly focused on whole-body cooling. However, delayed induction and systemic complications have limited the clinical application of whole-body cooling. As a selective cerebral hypothermia, the selective intra-arterial brain hypothermia treatment has the characteristics of rapid and even induction of hypothermia, and less affecting the core body temperature. Therefore, it has become a promising treatment modality. This article reviews the application of selective intra-arterial brain hypothermia in acute ischemic stroke and its advantages and limitations in order to provide reference for further experimental studies and future clinical trials.

OBJECTIVE:To investigate the effect of clinical pharmacist intervention on prophylactic application of antibiotics in cardiothoracic surgery. METHODS:Medical records of patients underwent cardiothoracic surgery were collected from our hospi-tal during Mar. to Apr. in 2014 (before intervention) and during Jun. to Jul. in 2014 (after intervention). Those were divided into pre-intervention group(n=115)and post-intervention group(n=119). The prophylactic application effect of antibiotics was com-pared before and after intervention. RESULTS:After intervention,the rates of prophylactic application were decreased significantly from 96.5% to 72.3%;the rationality rate of antibiotics selection was improved significantly from 27.9% to 94.2%;The course of prophylactic medication decreased significantly from(5.4±2.8)days to(2.3±1.8)days;the difference had statistical significance before and after intervention(P<0.01). The postoperative infection rate was decreased from 13.0% to 5.9%,the difference had no statistical significance(P=0.074). The average hospitalization time,average drug costs,and average hospitalization expenses were decreased significantly,the difference had statistical significance(P<0.05 or P<0.01). CONCLUSIONS:Clinical pharmacist inter-vention to prophylactic application of antibiotics in cardiothoracic surgery can control the infection effective and guarantee reason-able and safe use of drugs during perioperative period.
