AIM: To analyze the characteristics of internal fixation implantation therapy for comminuted patella fracture. METHODS: A computer-based search of Pubmed database and Chinese Journal Full-text Database was undertaken, and the quotations of each literature were checked after the primary screening. Inclusion criteria: the papers about the application of internal fixation materials in comminuted patella fracture, those published in authority journals within recent five years were preferred. Exclusion criteria: repeated study or Meta analysis. RESULTS: Internal fixation approach differs as the fracture type. Tension band fixation is generally accepted to treat transverse patella fracture. Kirschner wire plus tension band fixation are inferior to transverse fixation, but in comminuted fracture it can induce more complications; despite of wide application, nickel titanium patella fixator is unsuitable for comminuted fractures due to its hypersensibility and carcinogenicity; silk or steel wire loop fixation fits various comminuted fractures, but metal cerclage is predisposed to induce infection and breakage because of insufficient fixation force. CONCLUSION: There is no common way for comminuted patella fracture therapy. Further researches on material and method which can cure all kinds of comminuted patella fracture are still needed.

AIM To explore the effects of Sini Decoction (Aconiti lateralis Radix Praeparata,Zingiberis Rhizoma,Glycyrrhizae Radix et Rhizoma) on rat myocardial fibrosis induced by isoproterenol.METHODS Forty SD rats were randomly divided into blank,model,captopril [100 mg/(kg · d)] and Sini Decoction [3.8 g/(kg · d)] groups,with ten rats in each group.Except for the blank group,the rest rats were given subcutaneous injection of isoproterenol [5 rg/(kg · d)] to prepare myocardial fibrosis model,and successive administration lasted for four weeks.At 20 h after the last administration,hemodynamics changes of heart were detected;heart weight indexes were calculated;the changes of myocardial pathological morphology were observed by HE and Masson staining;NO level in serum was measured by nitrale reduetase;SOD activity in serum was measured by xanthinoxidase method;MDA level in serum was measured by thiobarbituric acid method;the protein expressions of RhoA,ROCK1 and eNOS in myocardial tissue were detected by Western blot method.RESULTS Compared with the model group,the cardiac function of rats was significantly improved;the myocardial collagen content was significantly decreased;the MDA level in serum was obviously decreased;the NO level and SOD activity were significantly increased;the protein expressions of RhoA and ROCK1 in myocardium tissue were significantly reduced,and the protein expression of eNOS was markedly increased in the Sini Decoction group.CONCLUSION Sini Decoction can improve the isoproterenol-induced myocardial fibrosis in rats,and its mechanism may be related to inhibiting the RhoA/ ROCK signaling pathway,in turn,raising the expression of eNOS,which leads to reduced oxidative stress.

Objective To investigate the prevalence of TT virus infection in pregnant women in Shenzhen and the role of mother-to -child transmission route in the TTV infection. Methods TTV DNA were detected by nested PCR in sera, cord blood and breast milk samples from 400 mother-infant pairs. TTV DNA positive mothers were followed up for 6 months for monitoring TTV DNA. Thirty two TTV DNA PCR products amplified from blood and milk samples of 13 mother-infant fairs were cloned and sequenced. Results By means of PCR, TTV DNA were detected in 62 of mothers' serum samples, 4 of 400 cord blood samples, and 20 of 400 milk samples, respectively. Therefore, 6.5%(4/62) of infants are likely to be infected with TTV from their mothers during the fetal period. Direct sequencing of TTV DNA from 13 mother-child pairs showed identical isolates (nucleotide homology from 97.5% to 99%), Follow-up sera of 42children, whose mothers were TTV DNA positive, showed 16 cases turned out to be existence of TTV viremia at 6 months old. Conclusions Our data proved the mother-to-child transmission route of TTV infection.TTV can be transmitted transplacentally and postnatally by the way of breast feeding as well. The increase of TTV prevalence during the 6 months after birth, suggests the postnatal transmission route of TTV may be of more importance, and further study is needed to address whether preventive measure should be done.

[Objective]To study the effects of titanium cable system used as a treatment alternative for comminuted patella fractures.[Method]Fifty-seven cases of comminuted patella fractures were treated from November 2004 to August 2007.The patients were divided into three groups:the group of titanium cables,AO modified tension band and nickel titanium-patella catcher respectively,according to the choice of internal fixation.The operation time,the amount of blood loss,the first knee exercise time after operation,length of hospitalisation,medical expenses,time off for employees,complication and long-term knee function were studied.All the data were analyzed and compared by statistical ways.[Result]The 57 patients were followed up for 11 to 48months(means,22.4 m).Patients who were fixed with titanium cables could start most early extending and flexing the knee(5.6 d after operation),but most expense in medical usages(9500 RMB).The good or excellence rate was 95.1% in patients treated with titanium cables cerclage,which was better than that of the other two groups.[Conclusion]Titanium cables cerclage can cure comminuted patella fractures.The method had advantage of better long-term curative effect and less complication,and so on.It's worthy to be recommended for the therapy of comminuted patella fracture.

Objective Through adverse event reporting module in hospital nursing manage-ment system, research group screened out the fall incidence higher departments to explore the effect of workshop mode in tralning nurses' prevention of falls of hospitalized patients. Methods A tralning team was set up under the guidance of hospital nursing department, to determine the content of the project and implementation process. 176 registered nurses were received tralning of fall-prevention by workshop mode, compared the differences in fall prevention knowledge level of nurses before and after tralning. Likert's 5-points were used in the investigation for satisfaction of participants. Results Aver-age score of after tralning was (18.66 ±1.32). The previous increase was (2.42 ±2.06). The differences was statistically significant (P=0.000). The comprehensive evaluation of the tralning mode from the participants was over 92.00%, except for the tralner was 89.77%. Participants were satisfied with the workshop mode . Conclusion Application of workshop in tralning program can improve nurses' knowledge of fall-prevention and guarantee patient safety.

BackgroundFew studies have compared change in the health-related quality of life (HRQL) following treatment of non-ST-elevation acute coronary syndrome (NSTE-ACS) with either percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG). This study is tocompare changes in HRQL six months after hospital discharge between NSTE-ACS pa-tients who underwent either PCI or CABG.Methods HRQL was assessed using the Seattle angina questionnaire at admission and six months after discharge in 1012 consecutive patients with NSTE-ACS. To assess associations of PCI and CABG with HRQL changes, logistic regression models were constructed treating changes in the score of each dimension of the Seattle angina question-naire as dependent variables.Results Although both the PCI and CABG groups experienced angina relief and other improvements at 6-month follow-up (P<0.001), the CABG relative to PCI group showed more significant improvements in angina frequency (P= 0.044) and quality of life (P= 0.028). In multivariable logistic analysis, CABG also was an independent predictor for both im-provement of angina frequency (OR: 1.62, 95%CI: 1.09-4.63,P= 0.042) and quality of life (OR: 2.04, 95%CI: 1.26-6.92,P= 0.038) relative to PCI.Conclusions In patients with NSTE-ACS, both PCI and CABG provide great improvement in disease-specific health status at six months, with that of CABG being more prominent in terms of angina frequency and quality of life.

Objective To study the effects of He-Ne laser irradiation dosage on the expression of heat shock protein ( HSP70) and CyclinD_1 in rats with chronic atrophic gastritis ( CAG). Method Fifty-two adult male Wistar rats were randomly divided into five groups: a normal control group, model group and three groups receiving different doses of He-Ne laser irradiation. CAC was induced using an enema of 2% sodium salicylate and 30% alcohol combined with irregular fasting and forced exercise as pathogenic factors. Laser irradiation was applied for 20 days (large dose 6.24 J/cm~2 , medium dose 4. 80 J/cm~2, small dose 3. 36 J/cm~2). The changes in HSP70 and CyclinD_1 expression were observed. Results The expression of HSP70 and CylinD_1 were highest in the normal control group and the small dose laser group. Compared with the model group, the average expression of HSP70 and CyclinD_1 increased significantly in the small dose group. Conclusions Irradiation with a He-Ne laser at 3. 36 J/cm~2 provides good adjuvant therapeutic effect for CAG in rats. After irradiation, the expression of HSP 70 and CyclinD_1 increased. HSP is important in improving mucosal defenses and promoting cell proliferation in CAG, and it can be promoted through small doses of He-Ne laser irradiation.
