Objective To study the relationship between helicobacter pylori(Hp) infection and iron deficiency anemia(IDA) in children. Methods The observation group contained 26 cases and control group 22 cases.Seroferroprotein(SF) and blood routine were detected.Results There was statistically significant difference in both groups on the SF,hemoglobin,red blood cellcount,mean corpuscular volume and mean corpuscular hemoglobin concentration (P0.05). Conclusion Hp infection may be related to IDA in children.

Drug clinical trial is an important link in the chain of new drug research and development. The results of drug discovery and development directly depend on the extent of standardization of clinical trials. Therefore, improving the quality of drug clinical trials is of great importance, and drug clinical trial institutions play a crucial role in the quality management of drug clinical trials. After years of development, the overall level of drug clinical trials has advanced rapidly in China, and a large number of clinical trials of traditional Chinese medicine have also been carried out. However, there is still a big gap between our country and developed countries. Therefore, for the construction and management of Chinese drug clinical trial institutions, there is still a long way to go. This study aims to analyze the current development of drug clinical trial institutions in China and explore the existing problems from three aspects, including current situations of institutional organization and management, regional and professional distributions, and quality control. And some suggestions are put forward finally, including support of traditional Chinese medicine, introduction of drug-risk management system, and construction of information management.

Objective:To analyze the clinical features of the patients with drug-induced liver injury ( DILI) combined with hepati-tis B to improve the awareness and attention to the disease by medical workers. Methods:Using retrospective analysis, the patients di-agnosed with DILI combined with hepatitis B from a tertiary-hospital were analyzed from January 2013 to January 2014. Results:Total-ly 30 cases of DILI combined with hepatitis B were collected, the number of male patients was higher than that of female patients, and most of them were elderly patients. The symptoms included weak, anorexia, yellow skin and sclera, tired of the oil, nausea, abdominal distension and so on. The patients with severe liver damage accounted for 80. 0%, 16. 7% was with moderate liver damage, and 3. 3%was with mild liver damage. Thirteen cases were mixed type, ten cases were hepatocellular type, and seven cases were cholestatic type. Conclusion:Middle-aged men may be prone to the disease, and the clinical manifestations are complex and diverse. Severe liver damage is majority, and often shows as mixed liver injury.

AIM: To study antiasthmatic effect of citral from aqueous extract of fruit of cubeb litsea tree and its mechanism.METHODS: By inducing asthma with Ach-histamine method in guinea pig,cough with ammonia in mice and the output quantity of phenol red from the trachea in mice,the antiasthmatic was observed,preventing cough and eliminating phlegm effect of citral. By measuring the tension of guinea-pig isolated tracheal rings,the both influence of citral was observed on isolated guinea pig tracheal rings and inhibition's effects of citral on contraction induced by Ach.RESULTS: Citral prolonged apparently the incubation period of asthma due to Ach-histamine solution in guinea pig and the coughing incubation period,reduced coughing frequency induced by ammonia in mice,increased excretion of phenol red from the respiratory tract in mice,inhibited the constrictions induced by Ach,and shifted the dose-effect curves of Ach to the right.CONCLUSION: Citral has functions of expelling phlegm,relieving cough and resisting asthma,satisfactory bronchi spasmolysis.

目的探讨矫形器训练对改善下肢功能障碍患者日常生活活动能力的作用。方法将64例下肢功能障碍患者随机分为矫形器组和对照组各32例。对照组采用自我锻炼方法,矫形器组安装矫形器,两组均同时接受正规康复训练、心理指导及康复护理。于分组前及分组治疗4周后评定患者的疗效。结果两组患者的Barthel指数评分均有一定程度的提高,但矫形器组患者的评分明显优于对照组(P<0.01)。结论下肢功能障碍患者使用矫形器4周后即能明显提高日常生活活动能力。

AIM: To investigate therapeutic effects of recombinant human growth hormone(rhGH) on rat sepsis and its possible mechanisms. METHODS: Mean arterial pressure (MAP), levels of plasma TNF?,IL-1? and endotoxin,leukocyte count and survival rate within 1 week were determined after E. coli injection among control group,sepsis group and sepsis+rhGH group. RESULTS: (1)rhGH diminished the decrease of MAP, reduced plasma endotoxin and TNF? levels and increased neutrophil ratio in total leukocytes in sepsis rat. rhGH increased survival rate within 1 week on sepsis rat. (2)No changes were found in IL-1? level among the three groups. CONCLUSION: rhGH showed desirable beneficial effects on rat sepsis, which may attribute to: improving circulatory function; maintaining intestinal mucosa barrier, attenuating bacteria/endotoxin translocation and inhibiting the production and release of TNF?.

Objective To investigate the application of evidence-based nursing in the patients with cerebrospinal fluid leakage (CSFL) after vertebrae surgery.Methods 60 cases of patients were randomly divided into the observation group and the control group (30 cases in each),the control group was given conventional nursing,the observation group used evidence-based nursing,which was established by referring to some data and literatures according to a series of related nursing problems,getting direct and indirect evidence,and through analysis and summarizing to set up the nursing project for implementation.The incidence of intracranial hypotension headache,hyponatremia,wound healing disorders,infection of intervertebral space were compared.Results In the observation group,incidence of postoperative intracranial hypotension symptoms,postoperative hyponatremia,the incidence of wound healing disorders was statistically different from that of the control group.The incidence of infection in two groups showed no significant difference.Conclusions Using evidence-based nursing can reduce a series of complications in patients with CSFL after cervical surgery,control infection effectively,improve patients' comfort and improve the quality of nursing.

Aim: To elucidate the structure of an acidic polysaccharide from Cordyceps sinensis and to study its protective effect on renal cell injury by cisplatin. Methods: After Cordyceps sinensis acidic polysaccharide( CAPS) was isolated and purified, the purity and molecule weight were detected by high performance gel permeation chro-matography( HPGPC). Based on the UV spectrum, FT-IR spectrum, monosaccharide composition and GC-MS, the structures were elucidated. Cisplatin-induced injury of Madin-Darby canine kidney( MDCK) cell line was protec-ted by the blood serum with CAPS. Results: The purity of CAPS, with a molecule weight of 2. 7×10~4, was about 99%. It consisted mainly of mannose, glucose and galactose. When the serum with CAPS reached 2.5%, it showed difference compared with the cisplatin group (P <0. 05) on the protective effect of renal cell injury. It showed significant difference( P <0.01) when the serum with CAPS exceeded 5%. Conclusion: CAPS has a pro-tective effect on the renal cell injury in vitro.
