[Objective]To evaluate the clinical result after treatment on fracture of distal radius with different fixations of the wood splint/plaster splint/"T" model plate.[Method]There were 236 cases with the fracture of distal radius,there were divided three types of A,B,C according to the AO classification,70 cases in 236 cases were treated with close diaplasis and external wood splint fixation,55 in 236 cases with external plaster splint fixation,III in 236 cases with operation and internal "T" model plate fixation.Results were evaluated by replacement and function after treatment,and percentage of excellence was compared with three different fixation.[Result]236 cases were all followed-up,mean follow-up period was 14.6 months(6~20months).The excellence rate of diaplasis was not significantly different in A and B type by comparing three different fixation,the excellence rate of function with wood splint fixation and "T" type plate internal fixation was better than that of plaster splint fixation in A and B type,there were not significantly difference about the excellence rate of function with the external wood splint fixation and the internal "T" model plate fixation.The excellence rate of function and reduction with"T" type plate internal fixation were better than with plaster splint and wood splint in C type.[Conclusion]The author suggests open reduction with "T" type plate internal fixation about C type fracture,close reduction and external wood splint fixation about A and B type distal radius fracture.

Human adenovirus is a DNA virus and a common pathogen of respiratory tract infection in children of China.Adenovirus can trigger a variety of mechanisms, thereby dissolving and killing lung cells.Consequently, it leads to such acute lung injury as acute respiratory distress and lung consolidation, and such pulmonary sequelae as bronchiolitis obliterates, unilateral transparent lung, bronchiectasis, and interstitial fibrosis.In this article, the mechanism underlying children lung injury caused by adenovirus was reviewed.

AIM: To explore the effects of high D-glucose on the mRNA and protein expression of lectin-like oxidized LDL receptor-1 (LOX-1) in endothelial cells and to study the possible mechanism by which diabetes is easily accompanied by vascular diseases. METHODS: Cell morphology was observed with inverted phasecontrast microscope. LOX-1 mRNA was detected by quantitative reverse transcription polymerase chain reaction in vascular epithelial cells cultured with different concentration D-glucose (7 5, 15 or 30 mmol/L) or with the same concentration D-glucose (15 mmol/L) in different time (0, 12, 24, 48, 72 or 96 h), LOX-1 protein expression was also examined by immunohistochemisty. RESULTS: Cells, exposed to high concentration D-glucose, were crude with clear profiles and bright granules in the plasma. Different high concentration D-glucose could induce LOX-1 mRNA expression and the effect of 30 mmol/L glucose on LOX-1 mRNA was the most significant (P

The effects of highly active antiretroviral therapy (HAART) to patients with AIDS in Hubei province of China were investigated in order to provide scientific evidence to reinforce the management of HAART. Self-made questionnaires and descriptive method of epidemiology were used to collect and describe the changes of clinical symptoms, HIV RNA concentration, and immune function of patients with AIDS. After HAART, the effective rate of fever, cough, diarrhea, lymphadenectasis, weight loss, tetter, debility and fungous infection was 92.4%, 90.85%, 92.91%, 90.73%, 93.69%, 89.04%, 92.34%, and 83.1%, respectively. Of 117 patients with detected HIV RNA concentration, 41.03% had declined over 0.5 log, and 52.99% less than 0.5 log. CD4(+)T cell count was obviously increased: the average number after HAART for 3 or 6 months was 237/microL (26-755/microL) and 239/microL (17-833/microL), respectively. HAART can improve AIDS patients' clinical symptoms, reduce HIV RNA concentration, and maintain immune function. It is very important for the effectiveness of HAART to raise clinical adherence of patients with AIDS and have a persistent surveillance.

Objective:To explore the structure of maternal verbal scaffolding features and develop a questionnaire on Mother's language scaffolding characteristics, so as to provide a quantitative, convenient and economical self-assessment tool for describing maternal verbal scaffolding features.Methods:On the basis of qualitative research and literature research, a questionnaire survey was conducted among 704 mothers of preschool children. After item analysis and exploratory factor analysis, a formal questionnaire was formed. Two weeks later, 106 mothers were retested to collect test-retest reliability data. Preschool children's expressive vocabulary checklist was used as external criterion.Data were analyzed by SPSS 18.0 and Amos 21.0.Results:(1)The formal questionnaire includes 28 items with two factors-detailed support factor and control rejection factor, the internal consistency coefficients of the two factors were 0.849 and 0.811, the project load was from 0 .482 to 0 .701, and the variance contribution rate was 40.36%.(2) AMOS 21.0 was used for confirmatory factor analysis, indicating that the two-factor structure met the requirements of psychometrics.( χ 2/ df=1.96, RMSEA=0.05, NFI=0.86, CFI=0.90, IFI=0.89). (3)The results of two-factor text-retest reliability were 0.840 and 0.871 as well as the results of split-half reliability was 0.801.The internal consistency reliability was 0.740.The external validity analysis showed that the mother's education level was positively correlated with factor Ⅰ( r=0.288, P=0.000), but not with factor Ⅱ( r=-0.091, P=0.052). There was significant difference in factorⅠbetween mothers with expressive vocabulary development delay children (52.22±10.56) and non delayed children (57.71±7.51) ( t=-5.07, P=0.000). There also was a significant difference in factor Ⅱ between mothers with expressive vocabulary development delay children (37.12±10.09) and non delayed children (31.53±8.59) ( t=4.61, P=0.000). (4)There was no significant difference in the characteristics of language scaffolding between boys(factorⅠ(58.08±8.14), factorⅡ(32.86±9.51)) and girls' mothers(factorⅠ(56.93±8.20), factorⅡ(31.42±8.48)). Analysis of the sample groups showed that age did not affect the verbal scaffolding features of preschool children's mothers( F1=1.633, P1=0.181; F2=0.758, P2=0.518). Conclusion:There are two factors in the questionnaire of the verbal scaffolding features questionnaire, which meet the criteria of psychometrics.The questionnaire of the verbal scaffolding features questionnaire is suitable for evaluating the characteristics of language scaffolding of mothers of preschool children aged 3-6.

Objective To improve the success rate of insertion of gastric lavage canal in patientswith tracheal intubation. Methods 70 patients with organophosphoms pesticide intoxication who neededgastric lavage after tracheal intubation were randomized into the test group and the control group, 35 easesin each. In test group, lavage canal was inserted through bite block orally and the bedside was raised till 70to 80 in angle. While in the control group, lavage canal was inserted directly through mouth with the posi-tion of hypsokinesis. The success rate of intubation was compared between the two groups. Results One-time success rate was 94.2% in the test group,which was statistically different from that of the control group(37.1%), P < 0.01. The complication of intubation in the test group was also lower than that of the controlgroup,which had statistical difference. Conclusions Through improvement of position to raise the bedsidetill 70 to 80 in angle, the insertion of gastric lavage canal through bite block orally was much better than thenormal one and it is worth applying.

Objective To determine the risk factors for development of succinylcholine-induced postoperative myalgia.Methods One hundred and fifty-five patients,aged 18-64 yr,of ASA physical status Ⅰ or Ⅱ,with body mass index of 20-30 kg/m2,scheduled for elective craniofacial surgery,were included in the study.Total intravenous anesthesia with propofol or combined intravenous-inhalational anesthesia with sevoflurane was performed during surgery.The patients were divided into 2 groups according to whether or not myalgia occurred within 24.h after surgery:myalgia group and non-myalgia group.Factors including gender,age,body weight,duration of surgery,method of anesthesia,dose of succinylcholine,preinjection of lidocaine or nondepolarizing muscular relaxants during induction of anesthesia,use of hormone (dexamethasone or methylprednisolone) and nonsteroidal analgesics (parecoxib sodium) during surgery,and consumption of fentanyl were recorded.The risk factors of which P values were less than 0.05 would enter the multivariate logistic regression analysis to stratify the risk factors for development of succinylcholine-induced postoperative myalgia.Results Forty-one patients developed postoperative myalgia,and the incidence of myalgia was 27.2％.The results of logistic analysis indicated that succinylcholine ＜ 1.5 mg/kg and no preinjection of lidocaine were closely correlated with the development of postoperative myalgia induced by succinylcholine.Conclusion Succinylcholine＜1.5 mg/kg and no preinjection of lidocaine are the risk factors for development of succinylcholine-induced postoperative myalgia in the patients.

OBJECTIVE:To systematically review the difference of phlebitis induced by Alprostadil injection with different ad-ministration routes,and to provide evidence-based reference for clinical rational use. METHODS:Retrieved from PubMed,EM-Base,Cochrane Library,CBM,CJFD,VIP and Wanfang database,RCTs about phlebitis induced by Alprostadil injection with dif-ferent administration routes were collected. Meta-analysis was conducted by Rev Man 5.2 statistical software after literature screen-ing,data extraction and quality evaluation according to Cochrane System Evaluator's Manual 5.1.0. RESULTS:A total of 20 RCTs were included,involving 2562 patients. The results of Meta-analysis showed that the incidence of phlebitis induced by intravenous injection was significantly higher than that induced by intravenous dripping [OR=4.11,95%CI(1.59,10.67),P=0.004] and intrave-nous pump [OR=3.50,95%CI(1.50,8.16),P=0.004]. The incidence of phlebitis induced by general apparatus infusion was signifi-cantly higher than that induced by fine filtering infusion [OR=0.03,95%CI(0.01,0.08),P<0.001],with statistical significance. CONCLUSIONS:The incidence of phlebitis induced by low-concentration of Alprostadil injection or fine filtering infusion is low-er,and that of intravenous injection is higher.

Objective To investigate the morphological changes of the head,body and tail of the hippocampus in patients with Alzheimer's disease (AD).Methods Totally 30 AD (AD group),30 mild cognition impairment (MCI) patients (MCI group) and 30 normal old persons (normal control group) underwent brain MR scan.Based on the MR images,the head,body and tail of the hippocampus were segmented and the volume was measured.The difference of the volume in total,head,body and tail of hippocampus in AD group,MCI group and normal control group were compared.The correlation between hippocampal volume and the scores of neurological assessment scale was analyzed.Results The left total,head,body and tail volume were greater than those of the right side in 3 groups (all P＜0.05).For the comparison of total volume of left and right sides among the 3 groups,AD group was less than normal control group (both P＜0.01) and MCI group (both P＜0.05),MCI group was less than normal control group (both P＜0.05).Compared with the normal control group,the head,body and tail volume of hippocampus of both sides were decreased in AD group (all P＜0.05) and the volume of left head,body and right head of hippocampus in MCI group were decreased (all P＜0.05).Both sides hippocampus's head and body volume of AD group were less than those of MCI group (both P＜0.05).The scores of minimum mental state examination (MMSE) were positively correlated with the total and the head,body,tail volume of bilateral hippocampus.Except volume of left tail,there were negative correlations between the scores of activities of daily living (ADL),clinical dementia rating (CDR) and the volume of total and head,body,tail of bilateral hippocampus,which were positively correlated with Montreal cognitive assessment (MoCA) score.Conclusion The volume of bilateral hippocampus was significantly reduced in AD patients.The head of hippocampal volume was significantly reduced and the body and tail was not obvious.
