  • Screening, Prevention and Treatment of Venous Thrombosis for 235 Lushan Earthquake Victims

    Objective To report the screening, prevention and treatment of venous thrombosis for Lushan earthquake victims in the West China Hospital of Sichuan University. Methods Among the Lushan earthquake victims screened by vascular color Doppler, those with detected venous thrombosis were treated reasonably, and those without detected venous thrombosis were prevented early. Results There were total 235 Lushan earthquake victims in the hospital as of the 11th day after earthquake, and they were screened by vascular color Doppler. Among 26 cases with detected venous thrombosis, 25 were lower limb venous thrombosis, and the other one was upper limb venous thrombosis. Three cases were treated by rehabilitation intervention alone, three cases were treated by drug intervention alone, and the other 20 cases were treated by both rehabilitation and drug intervention. As of 30 days after the earthquake, the reexamination results of 26 victims with venous thrombosis showed that: 11 cases improved, including 5 completely recanalization and 6 incompletely recanalization. Among the three cases with drug intervention alone, one got completely recanalization, accounted for 33.33%. Among the three cases with rehabilitation intervention alone, one got incompletely recanalization, accounted for 33.33%. Among the 20 cases with both rehabilitation and drug intervention, four got completely recanalization, accounted for 20.0%, and five got incompletely recanalization, accounted for 25.0%. Conclusion Most Lushan earthquake victims with venous thrombosis are the elderly and women, stay in the ICU, and suffer from fractures in different degrees. The timely prevention and treatment can relieve local pain, promote early entry in the rehabilitation treatment, and prevent pulmonary embolism and other risks. The rehabilitation intervention and/or drug intervention should be adopted to the victims with detected venous thrombosis as well as the victims without detected venous thrombosis but have high risk factors, for it can effectively prevent and treat the further thrombosis and other bad consequences of the detachment of thrombus.

  • Evidence-Based Nursing Practice of Best Turning Over Strategy for a Patient with the Risk of Pressure Ulcer

    Objective To formulate an evidence-based nursing strategy of turning over for a patient with the risk of pressure ulcer. Methods The personalized clinical questions were put forward based on the PICO and patient’s condition, and the following databases such as NGC, The Cochrane Library of DARE, CDSR, CCTR, MEDLINE, PubMed and CBM were searched to collect the best clinical evidences of turning over for preventing pressure ulcer. Results One clinical guideline, one systematic review and three randomized controlled trials were included finally. According to the retrieval outcomes, patient’s clinical condition, and patients and their family members’ willingness, a reasonable nursing plan of turning over was formulated: lie on the visco-elastic foam decompression bed, turn over every 4 hours, and combine supine position with alternation of left-oblique 30° position and right-oblique 30° position. During hospitalization, the grade-I pressure ulcer in size of 4×6 cm2 on patient’s sacrococcygeal region was clear, dry and not broken, and the other part of body with pigmentation had no occurrence of pressure ulcer. Conclusion Evidence-based approaches are helpful to provide patient with a nursing plan that meets the needs of both scientificalness and individualization.

  • Prevalence, Prevention and Treatment of Human Infection with H7N9 Avian Influenza Virus: Evidence, Challenge and Thinking

    H7N9, a novel avian influenza A virus that causes human infections emerged in February, 2013 in Anhui and Shanghai, China. The epidemic quickly spread to Zhejiang, Jiangsu and other neighbor provinces. As of May 30th, 2013, WHO had reported 132 cases, 37 (28%) of which died. Aiming at such serious outbreak of epidemic, we retrospectively analyzed its etiology, epidemiology, clinical characteristics, treatment, prevention and control based on data and evidence. Experience and evidence of the risk surveillance and management of such a novel anthropozoonosis lacks in China, or even lacks around the world. Quick and accurate identification of the rules and of the variation and transmission of avian influenza virus becomes a key to prevention, control and treatment. According to current best available evidence around the world, Chinese medicine and biomedicine should be put in to parallel use. Only realizing evidence-based decision making can we effectively prevent and control the epidemic, treat patients, and reduce the loss.

  • Effectiveness of Topical Fluoride on Prevention of Enamel Demineralization during the Orthodontic Treatment in China: A Systematic Review

    Objective To evaluate the effectiveness of topical fluoride on prevention of enamel demineralization during the orthodontic treatment in China. Methods The Cochrane Library(Issue 9, 2012), MEDLINE (1996 to 2012.10), EMbase (1974 to 2012.10), CNKI (1994 to 2012.10), VIP (1994 to 2012.10), WanFang data (1998 to 2012.10) and CBM (1978 to 2012.10) are searched for the randomized controlled trials (RCTs) and quasi-Randomized controlled trials (qRCTs) about topical fluoride preventing enamel demineralization during the orthodontic treatment. The bibliographies of the included studies were searched, too. Two reviewers evaluated the quality of the included studies and extracted data critically and independently, and then the extracted data were analyzed using RevMan 5.2 software. Results A total of 20 studies within 19 articles were included, which involved 26 323 teeth. The results of meta-analysis results show that, the rate of enamel demineralization of the fluoride varnish group (8.4%) was lower than that of the control group (16.0%) (OR=0.44, 95%CI 0.33 to 0.59, Plt;0.000 01); the rate of enamel demineralization of the fluoride coating group (8.3%) was lower than that of the control group (17.7%) (OR=0.46, 95%CI 0.35 to 0.60, Plt;0.000 01); the rate of enamel demineralization of the fluoride toothpaste group (9.0%) was lower than that of the control group (14.5%) (OR=0.59, 95%CI 0.49 to 0.71, Plt;0.000 01); the rate of enamel demineralization of the fluoride foam group (11.6%) was lower than that of the control group (18.2%) (OR=0.48, 95%CI 0.24 to 0.96, P=0.04); the rate of enamel demineralization of other groups (12.0%) was lower than that of the control group (21.8%) (OR=0.43, 95%CI 0.30 to 0.60, Plt;0.000 01). Two outcomes were low quality in the GRADE system and the other three are very low quality. Conclusion Current domestic evidence shows that topical fluoride is effective to prevent enamel demineralization during the orthodontic treatment. However, given the low methodological quality of most included studies, this conclusion still needs to be further proved by conducting more strictly-designed, high-quality and large-scale studies.

  • Efficacy and Safety of Acellular Dermal Matrix in Preventing Frey Syndrome: A Systematic Review

    Objective To evaluate the efficacy and safety of acellular dermal matrix (ADM) in preventing Frey syndrome.Methods Studies of acellular dermal matrix in preventing Frey syndrome were searched in The Cochrane Library (Issue 1, 2010), MEDLINE, EMbase, SIGLE, GreyNet, NTIS, CBMdisc, VIP, CNKI and WANFANG DATA from 1995 to 2010. All the studies were selected, extracted and evaluated by four reviewers independently, and meta-analyses were performed with RevMan 5.0.0 software. Results A total of 15 studies involving 472 participants were included in the review. The studies showed that implantation of the ADM was able to efficiently reduce the incidence of Frey syndrome, and the difference in both subjective and objective was significant between the two groups after the therapy (RR=0.11, 95%CI 0.06 to 0.18, Plt;0.01; RR=0.14, 95%CI 0.10 to 0.19, Plt;0.01). The rate of temporary facial nerve paralysis was lower than that of the control group but the difference was not significant (OR=0.78, 95%CI 0.37 to 1.66, P=0.53). The incidens of both seroma and mucocele were higher than that of the control group but the difference was not significant(OR=2.63, 95%CI 0.09 to 79.25, P=0.58) and they could be alleviated by placing drainage tube and partial pressure bandage. The incidence rate of salivary fistula was lower than that of the control group and the difference was significant (OR=0.24, 95%CI 0.08 to 0.69, P=0.009). Conclusion The result of this system review shows that, the ADM can effectively and safely reduce the incidence of Frey syndrome. To perform preoperative hypersensitivity check for iodine or iodophors, to conduct rapid frozen section for defining the character of tumor, to fix the ADM stably, to place vacuum-drainage and to make partial pressure bandage are suggested.

  • Epidemic Factors and Preventing and Management Countermeasure of Pulmonary Tuberculosis in Zhushan County

    Objective To investigate and analyze the epidemic characteristics and factors of pulmonary tuberculosis (PTB) to provide foundation and make prevention and treatment policy. Methods Statistical analysis was conducted to analyze the current existing PTB prevention and control data in the Center for Disease Control and Prevention of Zhushan County and corresponding prevention and treatment policy was proposed. Results Since 1997 when PTB was included into B infectious diseases in Zhushan County, 4 431 cases of PTB had been reported by the end of 2009. Annual reported incidence rate was 74.73 per 100 000 and the disease was found in 17 towns. All seasons witnessed the incidence but winter and summer had more sufferer. The youngest patient was 4 months whereas the oldest was 86 years old. The majority of the patients were from 20 to 59 years old, peasants were the main patients, and the incidence of male was higher than that of female. The use of chemotherapy resulted in a significant decline of PTB death rate. Poor immunity of elder group, population flow caused by poverty, low detection rate of patients and AIDS were the major causes to PTB epidemic. A lack of prevention and treatment in the grassroots hospital and difficulty to fully implement the Directly Observed Treatment, Short-course (DOTS) strategy in remote areas were also bottlenecks to PTB control process. Conclusion The followings should be performed to improve the quality of DOTS strategy implementation: strengthen the government’s commitment, provide policy and funding safeguard, conduct health education and health promotion widely, reinforce management according to the law, fully implement the DOTS strategy, and fortify the prevention and control construction.

  • The Prevalence Survey of Severe Acute Respiratory Syndrome Prophylaxis in 411 Medical Staff of Shanxi Province of China

    Objective To investigate the clinical effectiveness and adverse event of preventive medicine for severe acute respiratory syndrome (SARS), and provide clinical data for designing prospective clinical trial. Method Retrospective study on medical staffs, that were exposed to SARS patients, was conducted in two main SARS designated hospitals to obtain information such as SARS exposure risk and preventive measures (medical and others). According to the type of preventive medicine, they were assigned to earthworm’s nucleases and protease (ENP) group, interferon group and blank control group respectively. Exposure risk, suspected sub-clinical infection rate and adverse event rate were compared between the three groups. Results Non-medical preventive measures used in each group were consistent, but the exposure intensity to risk factors between groups was statistically different, which biased the evaluation of clinical effectiveness of preventive medicine. The rate of suspected sub-clinical infection in earthworm’s nucleases and protease (ENP) group, interferon group and control group were 4.5%, 4.5%, and 9.9% (Pgt;0.05), respectively; and adverse event rate were 19.6%, 13.6% (Pgt;0.05), and 0%, respectively. Conclusions Suspected sub2clinical infection rate in ENP group, interferon (INF) group were lower than that in control group, which indicated that these two medicines might be effective in preventing SARS. Adverse event rate in ENP group was similar to that of interferon group, and the symptoms were mild in both groups, which was in accordance with the result of in vitro experiments. ENP spray is a kind of biological preparation; further purification may reduce its adverse event rate. However, because there had excessive confounding factors, especially because of the unequal of exposure risk between three groups, the results of this study can only provide insights to design prospective clinical trial in the future.

  • Interventions for Treating Asymptomatic Impacted Wisdom Teeth in Adolescents and Adults

    Objective To evaluate the effect of prophylactic removal of asymptomatic impacted wisdom teeth in adolescents and adults compared with the retention of these wisdom teeth. Methods We searched the Cochrane Oral Health Group Trials Register (to 4 August, 2004), the Cochrane Central Register of Controlled Trials (CENTRAL), PubMed (1966 to 4 August, 2004), EMBASE (1974 to 4 August, 2004). There was no restriction to publication of language. Key journals were handsearched. An attempt was made to identify ongoing and unpublished trials. All randomised or controlled clinical trials (KCTs/CCTs) comparing the effect of prophylactic removal of asymptomatic impacted wisdom teeth with no-treatment (retention) were included. Assessment of relevance ,validity and data extraction were conducted in duplicate by three independent reviewers. Where uncertainty existed, authors were contacted for additional information about randomisation and withdrawals. The quality assessments of the trials were carried out. Results Only three trials were identified to fulfill the selection criteria. Two complete RCTs assessed the influence of prophylactic removal on late incisor crowding in adolescents. One ongoing RCT was identified, but the researchers were unable to provide any data and intended to publish in the near future. Although both complete trials met the inclusion criteria, different outcome measures were prevented us from pooling data. Conclusions No evidence has been found to support or refute routine prophylactic removal of asymptomatic impacted wisdom teeth in adults. There is some reliableevidence that suggests that the prophylactic removal of asymptomatic impacted wisdom teeth in adolescents neither reduces nor prevents late incisor crowding.
