Malaria remains a serious public health problem,especially in developing countries. With the deepening of the un-derstanding of vivax malaria,Plasmodium vivax is also attracting more and more attention. An effective drug treatment is the foun-dation of controlling or even eliminating malaria. In recent years,more and more reports of chloroquine-resistance Plasmodium vivax have been reported. Plasmodium vivax chloroquine resistance has been a focus problem in vivax malaria prevention and treat-ment. In this paper,the research progress on distribution situation,detection methods and molecular markers of Plasmodium vivax chloroquine resistance is summarized.

In order to investigate the change in and relationship between endothelin 1(ET 1) and nitric oxide(NO) in hypoxic pulmonary hypertension(HPH),the content of ET 1 and NO in plasma and lung tissue homogenate, the expression and localization of ET 1, constitutive and inducible nitric oxide synthase(cNOS,iNOS) using immunohistochemistry in HPH of rats were assayed. The effect of NOS inhibitor nitro L arginine methyl ester(L NAME) on the content of ET 1 was also studied. The results showed that the content of ET 1 and NO in plasma of the HPH rats were significantly higher than that of controls; positive expression of ET 1 and iNOS were enhanced in the endothelium of vessels, the epithelium of bronchi and the smooth muscle of vessels and bronchi,but the expression of cNOS weakened The content of ET 1 in plasma and lung tissue homogenate were increased after administration of L NAME. The results indicate that in the normal animals, NO may suppress the secretion of ET 1. The increased ET 1 may play an important role in the development of HPH, and the induced iNOS may be the result of functional adaptation to chronic hypoxia.

Objective To explore the application and significance of multiple clinical pathway training oriented teaching model in clinical teaching of laboratory diagnostic. Methods Totally 50 medical students enrolled in the Second Military Medical University from September to December in 2015 were divided into experimental group and control group. The course consists of theoretical teaching and experi-mental operation. The pathway group (n=25) were introduced into multiple clinical pathway training oriented teaching method. The theoretical teaching was carried out bysimulation examination application, simulation interpretation and simulation diagnosis and treatment, while the experimental course was carried out by using video teaching combined with actual operation. The control group was taught by traditional teaching method using slide teaching and operation display. The theoretical test including case study and operational skill tests were performed among students in both groups after 10 class hours training . The satisfaction questionnaires were conducted to evaluate the effectiveness and satisfaction of teaching guided by clinical pathway. Differences were compared with independent sample t testing using GraphPad Prism 5.0 statistical software. Results The medical records about professional theoretical test including case study and opera-tional skill test in the pathway group were superior to those in the control group with significant statistical difference (both P<0.05). The records of medical students were (81.84±7.21), (42.00±2.79) in the pathway group and (76.24 ±6.98), (37.00 ±3.71) in the control group. The questionnaire result showed that the pathway group's satisfaction was high, especially with the theoretical knowledge andsceneteaching (higher than 80％). The pathway group believed that multiple clinical pathway training helped to improve learning interest and clinical thinking ability . Conclusions Multiple clinical pathway training oriented teaching model is helpful for the medical students to achieve the basic idea of clinical pathway, improve the profes-sional ability, enhance the interest of learning and the quality of teaching, standardize teaching and promote teaching and learning.

Objective To construct recombinant Mycobacterium smegmatis vaccine expressing Cysticercus cellulosae cC1 anti-gen. Methods The recombinant pET28a-cC1 plasmid was extracted and double digested by Xho I and BamH I restriction en-zymes,and shuttle plasmid pMV261 was extracted and double digested by Hind III and BamH I restriction enzymes. Both frag-ments were modified by Klenow fragment to form blunt end,then the large fragments of cC1 and pMV261 plasmid were purified and ligated by T4 ligase enzyme. The recombinant pMV261-cC1 plasmid was constructed and sequenced. Then the pMV261-cC1 plasmid was transformed into Mycobacterium smegmatis by the electrotransformation method. The recombinant cC1-Mycobacterium smegmatis was induced by heat and identified by the Western blotting method with the sera of cysticercosis patients. In addition, the growth states of the Mycobacterium smegmatis and the recombinant cC1-Mycobacterium smegmatis were compared and the growth curves were drawn. Results The restriction enzyme and sequencing results showed that the recombinant pMV261-cC1 plasmid was successfully constructed. After heat induction,a 40 kD band was showed by PAGE analysis of cC1-Mycobacterium smegmatis. The Western blotting results showed that the sera of cysticercosis patients could recognize the 40 kDa band,which sug-gested that cC1 protein was expressed in Mycobacterium smegmatis. Compared with the Mycobacterium smegmatis,the recombi-nant cC1-Mycobacterium smegmatis showed no significant difference in proliferation characteristics. Conclusion The recombi-nant cC1-Mycobacterium smegmatis vaccine has been successfully constructed.

Objective To detect the prevalence of hyperuricemia and its relationship to chronic kidney disease(CKD) in the residents of Guangxi, and to discuss the risk factors for the hyperuricemia associated renal damage. Methods The residents aged 18-75 years old(n=6 273) in Xiangshan community,Guilin, were screened by means of cross-sectional study. Blood pressure was measured at 8:00-9:00.Fasting blood and urine samples were collected to determine blood glucose, lipid, insulin, creatinine, and urine albumin. Results The prevalence of hyperuricemia in the community residents was 23.5% in all cohort, being significantly higher in male residents than in female(28.4% vs 19.7%,P＜0.01). The prevalence of CKD was 21.6% in all cohort, and was 24.9% in males and 19.0% in females(P＜0.01). The prevalence of CKD was 30.4% and 18.9% respectively in residents with and without hyperuricemia(P＜0.01).The prevalence of CKD in males with hyperuricemia(34.3%) was significantly higher than in males without hyperuricemia(21.2%) and females with hyperuricemia(25.9%, all P＜0.01). CKD was only positively related to low-density lipoprotein cholesterol, blood glucose, and systolic blood pressure shown by logistic regression analysis. Conclusions The prevalence of hyperuricemia markedly increases in the urban residents, which contribute to the raised prevalence of CKD. Slightly elevated blood uric acid level is associated with raised prevalence of CKD.

Objective To understand the status of resistance to multiple insecticides and the frequencies of kdr mutations in Culex pipiens pallens from north?central Anhui Province. Methods From July to September,2014,the C. pipiens pallens mosquito larvae were collected in Huaibei,Bengbu and Chuzhou cities of the north?central Anhui Province and reared to adults. The female adult mosquitoes at 3-5 days post emergence were tested for susceptibility to the four insecticides,namely 0.05%deltamethrin,5%malathion,0.1%bendiocarb and 4%DDT,by using the standard WHO resistance tube bioassay. The detec?tion of the point mutations of the kdr gene at codon 1014 was conducted by PCR and DNA sequencing in the deltamethrin?resis?tant and?susceptible mosquitoes. Results High levels of resistance to all the four insecticides were found in all the three tested populations,although mosquito mortality varied among populations and test insecticides. Among the test insecticides,DDT showed lowest mortality with no significant difference(F=1.027,P>0.05)in all test populations,whereas significantly differ?ent mortalities were observed among populations for the remained three insecticides tested(deltamethrin,malathion,and ben?diocarb)(F = 23.823,33.955,128.841;all P < 0.01). Two types of non?synonymous kdr mutation at codon position 1014 (L1014F and L1014S)were observed. A positive correlation between L1014F mutation frequencies and deltamethrin resistance levels were detected in the three mosquito populations(r2=0.718,P<0.01). Conclusions The observed high levels of resis?tance to multiple?insecticides coupled with the occurrence of medium to high kdr frequencies in populations of C. pipiens pallens could profoundly affect the mosquito vector control programme in China. The local health departments need to strengthen vector dynamic monitoring and implement rational resistance management strategies.

Objective To analyze the clinical application of HLA donor specific antibodies (DSAs) detected by Luminex single antigen beads,and to discuss the impact of early intervention on renal function.Method In 64 cases of living-relative renal transplantation,DSA was detected using a Luminex single antigen assay before and after transplantation.The positive recipients were given large doses of intravenous irnmunoglobulin (IVIG) and increased doses of mycophenolate mofetil (MMF).The relationship between DSA and renal function was analyzed.Result DSA was negative in all recipients before transplantation.Ten cases of DSA positive recipients were found in HLA mismatch after transplantation.After the intervention,two cases of DSA positive recipients became negative,immunofluorescence intensity was decreased by more than 50％ in 6 cases,and no significant reduction was found in the other two cases.Antibody-mediated rejection (AMR) occurred in two cases of intervention ineffective recipients after 3 to 6 months and the renal function was impaired.Conclusion Dynamic monitoring of DSA using Luminex single antigen beads may timely predict changes of renal function.Early application of large doses of IVIG and increasing doses of MMF can reduce the incidence of AMR.

BACKGROUND: As a candidate gene of congenital heart disease, ACTC1 gene is related to congenital atrial septal defect inhumans.OBJECTIVE: To perform a mutation screen of ACTC1 gene in 110 nuclear families of congenital heart disease.METHODS: A case-control study was conducted based on 110 nuclear families of congenital heart disease and 300 normalhuman beings with no reported cardiac malformation. Six fragments in the coding region of ACTC1 gene was amplified by PCR invitro using five primers pairs. PCR products were screened for gene mutations.RESULTS AND CONCLUSION: A novel G-to-A variant was found at the third nucleotide of the intron downstream from exon 5.This mutation existed in a 5-year-old female with an isolated ventricular septal defect and her 30-year-old father, who had noreported cardiac anomalies. This mutation was not detected in 300 normal controls. These findings indicate that the mutation maybe related with congenital ventricular septal defects in humans.
