At present,peripherally inserted central catheter (PICC) and totally implantable access port (TIAP) are most commonly used for the medium-term and long-term ccntral vcnous infusion in China,which is mainly adopted for long-term repeated chemotherapy,nutritional support and other clinical treatments.As an advanced infusion route,this technique needs to be further popularized in clinical practice to benifit the majority of patients.However,in aspect of the implantation,use,maintenance,and the diagnosis and treatment of complications of long-term central venous access,there are still a lot of problems,to which sufficient attention should be paid.Standard implantation and maintenance are of great importance for the safe implantation of central venous access and long-term safe use.This paper aims to make a comprehensive review concerning the problems of long-term indwelling of central venous access,the basic solutions,and the whole course management of central venous access.In order to promote the technique of central venous access to continually develop,the multidisciplinary collaborative team with tacit cooperation,standardized system and regulatory process should be emphasized.

[Objective]To study the effects of AO double plates in internal fixation of humeral intercondylar fractures and to analyze the causes of the disfunction in elbow.[Method]From March 2001 to March 2006,21 cases (male 14, female 7) of humeral intercondylar fractures were reviewed, with an average age of 35.3 years (ranged,15～64 years).Left elbow:9 cases;right elbow:12 cases.According to AO/ASIF classification,type C1∶6,type C2∶10, and type C3∶5,2 cases of all were open fractures. Posterior operating approach of elbow: trans-olecranon osteotomy or trans-triceps-side approach and internal fixation by standard method of AO double plates were performed in all cases.The patients began the active training of elbow joint as soon as possible postoperatively.[Result]Twenty-one cases were followed up for 8～38 months and the average time was 14.8 months.Bone union was obtained in all cases.One case complicated wound infection,it recovered after 3 weeks of dressing.And 1 case complicated with radial nerve injury,which recovered with neural nutrients.According to the Cassebaum scoring system,the effects were evaluated as excellent 7,good 10,and fair 4,and the excellent-good rate was 80.9%.[Conclusion]The application of AO double plates was proved to be a good method to treat humeral intercondylar fractures at present. But the severity of the bone comminution and soft-tissue lesion, the effective fixation,earlier active exercise were the main causes that influence the functional recovery of elbow joint.

OBJECTIVE To assess the prevalence and analyze the influence factors of laryngopharyngeal reflux disease(LPRD) in the Fuzhou region, in order to provide a theoretical basis for the development of prevention and control measures for LPRD. METHODS A questionnaire survey in residents in Fuzhou by a random cluster sampling was carried out. Individual information, reflux symptom index(RSI) of Belafsky and risk factors were included. Patients more than 13 scores of RSI were defined as LPRD. Data were statistically analyzed. RESULTS A total of 4100 residents were investigated, 4063 of them were available. The prevalence of LPRD was 5.00%. Often eating too much, often drinking strong tea, menolipsis, rhinitis, tonsillitis were closely related to LPRD. CONCLUSION The prevalence of LPRD in Fuzhou region were closely related to many factors.

Essential hypertension (EH), a complex polygenic disease, is considered to the result of the genetic interaction of multiple gene alterations in concert with environmental factors. Evidences showed that angiotensin-converting enzyme (ACE) gene and G protein beta3 subunit (GNB3) gene are both important susceptibility genes for EH, and that there exists putative biological connection between the two genes in developing hypertension. To investigate whether hypertension was affected by gene-gene interaction between the two genes in the northern Chinese Han population, a case-control association study including 502 hypertensive cases and 490healthy controls was conducted, selecting the ACE gene I/D polymorpinsm and the GNB3 gene C825T polymorphism. Linkage disequilibrium analysis revealed a significant nonrandom distribution only in male hypertensives, indicating that interaction between ACE gene and GNB3 gene may predispose males to the occurrence of hypertension. Multivariate stepwise logistic regression in single locus analysis, with adjustment for common risk factors for hypertension, demonstrated that the OR for DD/ID versus Ⅱ for hypertension among men was significant (OR 1.57; 95% CI, 1.09 ～2.27; P = 0.016) in dominant genetic model. In combination analysis stratified with respect to gender, slightly significant ORs were found after adjustment in males: OR for TT vs CC, 0.11; 95%CI, 0.01 ～0.99; P = 0.049 within ACE DD genotype; OR for DD/ID vs Ⅱ, 1.52; 95% CI, 1.01 ～2.29; P = 0.047 within GNB3 CC+CT genotype. The results suggest that ACE, or a nearby gene, is a male-specific susceptible gene for hypertension, and that there may exist epistatic gene-gene interaction between ACE D allele and GNB3 825C allele.

Objective To investigate the association of SPRR2E gene and psoriasis vulgaris by sequencing the DNA of Chinese Han psoriatic families. Methods DNA was extracted from the peripheral blood cells of thirty-two Chinese psoriatic families. The sequence of the SPRR2E encoding region was measured by ABI377 DNA Sequencer. The linkage disequilibrium was assessed by extended transmission disequilibrium test (ETDT) and GENEHUNTER software. Results An A/G polymorphism at nucleotide 156 of the SPRR2E encoding region was identified. There were three genotypes, including AA, GG and AG. Although the single nucleotide polymorphism (SNP) did not change the encoding of amino acid, the single nucleotide polymorphism locus was associated with psoriasis vulgaris by the ETDT analyzing. The A-allele was found to be transmitted more frequently than that of the G-allele. GENEHUNTER analysis was concordant with the results of the ETDT. Conclusion A single nucleotide polymorphism (SNP) in SPRR2E gene encoding region is associated with psoriasis vulgaris in Han Chinese population.

Objective:To analyze morphological character of lateral tibial plateau fracture fragment, and its correlation to the presence of a meniscus injury in tibial plateau fractures.Methods:A total of 79 consecutive patients of the simple lateral tibial plateau fractures from July 201 1 to July 2015 were inclu-ded in this study,with 65 males and 14 females with an average age of (34.3 ±7.2)years and 22-61 years.According to Schatzker classification,21 cases were of Type Ⅰ,41 cases Type Ⅱ,and 17 cases Type Ⅲ.The characteristics of lateral tibial plateau fractures were evaluated by plain X-ray and magnetic resonance imaging (MRI ).The type and severity of meniscus injury were diagnosed by MRI scan. Three-dimensional measurements of the lateral fragment width (LFW),the lateral plateau depression (LPD),the coronal angulation of lateral fragment (CALF),and tibial plateau widening (TPW)were measured with Picture Archiving and Communication Systems(PACS)software.The patients with and without meniscus injuries were divided into different groups and analyzed respectively.Comparison of the above measurements between the two groups was analyzed by independent t test.Results:In all the 79 lateral tibial plateau fracture patients,26 cases (32.9%)of meniscus injuries were detected by MRI. Among all the meniscus injury cases,3 were of SchatzkerⅠ,16 SchatzkerⅡ,and 7 SchatzkerⅢ.In meniscus intact group,the average LFW was (22.0 ±2.8)mm while in meniscus injury group it was (21.3 ±3.3)mm (t =-1.008,P =0.317).The average LPD of non meniscus injury group was (5.4 ±2.8)mm,while in meniscus injury group was (8.7 ±2.8)mm (t=4.98,P=0.001).The average CALF of the two groups were 9.1°±6.1°and 10.6°±7.1°,and there was no significant dif-ference between the two groups (t=0.38,P=0.831).The average TPW was (3.0 ±1.1)mm,and (4.8 ±1 .7 )mm of the two groups.There were significant differences between the two groups (t =5.216,P=0.001).Conclusion:There was no obvious correlation between the LFD and meniscus inju-ry.The CALF of lateral tibial plateau fracture had no significant correlation with meniscus injury either. The degree of LPD and TPW may indicate injury of the meniscus in tibial plateau fractures.

Objective To understand the key risk factors of schistosomiasis transmission in Jingzhou City,so as to provide the evidence for improving the treatment of these risk factors. Methods Each village of six counties was investigated and 3 envi-ronments were surveyed each village for the distribution of Oncomelania snails and animal stools in the field. The results were ana-lyzed and the risk factors of schistosomiasis transmission were assessed. Results The density of living snails was 0.43 snails per 0.1 m2,the frequency of the frames with snails was 9.12%,and no schistosome infected snails were found. All of the animal stools collected from the field were from bovines. The schistosome positive rate of animal stools was 37.50%(3/8)among the environ-ments,and the schistosome infection rate of stools was 8.11%(3/37). The schistosome infection rate of animal stools was 0 near the residence living sites,and the positive rates were 12.50%and 8.33%in the ditches and slopes,respectively(χ2=0.07,P>0.05). Conclusions Bovine is still the main infectious source of schistosomiasis,i.e. the main risk factor of the disease transmis-sion. Therefore,the strategy of controlling bovine should be strengthened.

Objective:To observe the efficacy of calcined bovine bone(CBB)in the repair of animal bone defects.Methods:Ca-nine alveolar bone defect model,rat and rabbit calvarial critical size defect models were established respectively.All animals were randomly divided into 2 groups(n=6).The defects in the experimental group were repaire with CBB,those in the control group were not treated.The effects were observed by HE staining,Micro CT and Masson trichrome staining.Results:Canin alveolar bone de-fects were well repaired 8 week after operation.The skull defects in rabbits and SD rats were replaced by new bone 1 2 and 8 weeks after operation respectively.In all the control groups bone defects were not healed or not completely repaired.Conclusion:CBB is ef-fective in the repair of bone defects.

OBJECTIVE:To evaluate the effectiveness,safety and economy about Wenxin granules in the treatment of cardio-vascular diseases based on Meta-analysis. METHODS:Using“Wenxin granules”“Wenxinkeli”“Wenxin”as the search terms, searching PubMed,ProQuest,Springer,The Cochrane Library,CNKI,VIP and Wanfang data(Jan. 2000-Oct. 2015)through com-puter,relevant journals and conference papers by hand,randomized controlled trials about Wenxin granules in the treatment of car-diovascular diseases were screened and classified according to indications. Meta-analysis was performed by using RevMan 5.3 soft-ware,while cost-effectiveness analysis and minimum cost analysis were used for economic evaluation. RESULTS:Totally,38 liter-atures were involved,including 20 literatures of arhythmia,9 of premature ventricualr contraction,4 of coronary disease angina pectoris,3 of unstable angina pectoris,2 of pediatric viral myocarditis. Meta-analysis showed that compared with control drug, Wenxin granules showed better clinical efficacy for arrhythmia with less ADR;showed better clinical efficacy and ECG efficacy for premature ventricualr contraction with less ADR;showed better clinical efficacy for angina pectoris of coronary disease,unstable angina pectoris and pediatric viral myocarditis,with statistical significance (P<0.05). The incremental cost-effectiveness analysis showed that the additional cost of Wenxin granules in the treatment of above indications was worth it all,compared to control drug. Single factor sensitivity analysis supported the stability of results. CONCLUSIONS:Wenxin granules have a better effectiveness, safety and economy in the treatment of cardiovascular diseases,but still need high-quality evidence to support.
