Journal of Chinese Physician 2000;0(12):-
Objective To explore the molecular mechanism of c-jun antisense gene transfection in protecting cardiomyocytes from injury of hypoxia and burn serum treatment. Methods Burn sera were collected from wistar rat with 30% total body surface area(TBSA) Ⅲ degree burn injury, and the mixture gas containning 1% O 2 was used as hypoxia model. The c-jun antisense gene recombinant vector was constructed. Neonatal wistar rat cardiomyocytes cultured in vitro were treated with hypoxia and burn sera. c-jun antisense gene recombinant vector was transfected into the cultured cardiomyocytes. Expressions of c-jun, PKC? and JNK were detected with western blot in the transfected and non-transfected cardiomyocytes. Results Expression levels of c-jun, PKC? and JNK significantly increased in the non-transfected cardiomyocytes when treated by hypoxia and burn sera, up to maximum 24 hour after the treatment. Expression levels of c-jun, PKC? and JNK in the transfected cardiomyocytes decreased significantly compared with non-transfected cells. Conclusions The transfection of the c-jun antisense gene recombinant vector protected cardiomyocytes from injury of hypoxia and burn sera treatment via down-regulating PKC? and JNK expressions.

Objective To explore the effect of c fos antisense gene transfection on the protection of cardiomyocytes following hypoxia and burn serum treatment. Methods Burn serum was collected from Wistar rats with 30% total body surface area(TBSA) of Ⅲ degree burns. The mixture gas containing 1% O 2 was used as hypoxia model. The c fos antisense gene recombinant was constructed by genetic recombination technique. Cardiomyocytes from neonatal Wistar rats were cultured in vitro with hypoxia and burn serum treatment. c fos antisense gene recombinant was transfected into the cultured cardiomyocytes. Expression of c fos mRNA was determined by RT PCR. Expressions of c fos protein, troponin T and ? Tubulin in cardiomyocytes were determined by Western blotting in the transfected and non transfected groups. Results RT PCR results showed that the expression of c fos mRNA increased significantly in the non transfected group. But after transfection of c fos antisense gene recombinant, the expression of c fos mRNA decreased significantly as compared with the non transfected cardiomyocytes. Western blotting results showed that the expression of c fos protein in the transfected group decreased remarkably as compared with the non transfected group, but the expressions of ? Tubulin and troponin T increased significantly in the transfected group. Conclusion Burn serum and hypoxia can cause the injury of cardiomyocytes. c fos antisense gene recombinant transfection has the protective effect on cardiomyocytes exposed to burn serum and hypoxia.

Objective To understand the epidemiological characteristics of patients with advanced schistosomiasis in Hunan Province,so as to provide the evidence for formulating the advanced schistosomiasis prevention strategies and measures. Meth-ods The data of advanced schistosomiasis patients were collected and analyzed retrospectively with the cross section research method and description method in Hunan Province,2012. Results There were 5 722 advanced schistosomiasis patients in Hu-nan Province,and among them,4 112 patients were male(71.86%),and 1 610 were female(28.14%). Totally 5 311 patients came from the schistosomiasis endemic areas(92.82%)and 411 patients from non-schistosomiasis endemic areas(7.18%). The prevalence rate of advanced schistosomiasis was 8.46/10 000. The mean age of advanced schistosomiasis patients was 60.30 ± 11.63 years,and the youngest was 17 years old and the oldest 92 years old. In the age composition of advanced schistosomiasis pa-tients,the greatest number of cases was in the 60-70 years age group (32.72%). There were 3 595 cases of ascites type (62.83%),2107 cases of splenomegaly type(36.82%),11 cases of dwarf type(0.16%),and 11 cases of colon proliferation type (0.35%). Conclusion The prevalence rate of advanced schistosomiasis is relatively stable in Hunan Province,and the age of the patients showed an old aging trend. The salvation of advanced schistosomiasis patients in non-endemic areas should be strength-ened.

According to the requirement of the national assessment for achieving the infection control criteria, 42 villages (among them,25 villages belonged to the first stratum, and 17 villages belonged to the second stratum) in 14 counties from 5 provinces, including Hunnan, Hubei, Jiangxi, Anhui and Yunnan, were selected as sampling villages for the assessment.The results from the field assessment showed that 154 out of 9 067 people were found infected with Sckistosoma japonicum, with an average infection rate of 1.7% ranged from 0.31 % to 4.10% , and only Yongping Village from Weishan County and Tenglong Village from Eryuan County were not found any case. A total of 46 out of 3 323 head of cattle were infected with S. japonicum, with an average infection rate of 1.38% ranged from 0.26% to 3.79% , and no any infected individual detected in Nanling County. No outbreak occurred in those sampling villages. Therefore, it is indicated that the five sampling provinces have reached the national criteria on infection control of schistosomiasis.

Objective By a sequencing panel consisting of 50 targeted genes, aiming at depicting the molecular landscape of ET, PV, and PMF, which are three major subtypes of MPN, to provide valuable information in the diagnosis and prognosis of MPN.Methods A retrospective study was conducted of 53 patients from Huashan hospital and Changhai hospital. All patients were diagnosed in accordance with the 2016 WHO diagnostic criteria for MPN, including 31 cases of ET(11 males, 20 females, median age 55 years), 17 cases of PV(12 males, 5 females, median age 65 years), and 5 cases of PMF(4 males, 1 females, median age 67 years), and underwent next-generation of DNA sequencing of their bone marrow or blood samples. The genetic analyses were performed on bone marrow or peripheral blood. Referring to COSMIC, dbSNP, Clinvar and other public databases, we analyzed the sequencing data, and elucidated the mutation profile of MPN patients, combining with their clinic information. Results In addition to the typical JAK2, CALR, and MPL mutations, pathogenic mutations in other 11 genes were detected, as well as 4 SNPs that confer individual susceptibility to MPNs (rs4858647, rs9376092, rs58270997, rs621940). The average rate of mutated genes was 2.3 genes per patient. In all patients (53 cases), the mutated genes detected were TET2, EZH2, ASXL1, MIR662, SF3B1, BARD1, DNMT3A, KIT, RUNX1, TP53, NRAS according to their mutational frequency. Conclusions Applying next-generation sequencing technology, multi-gene sequencing of a bunch of typical BCR-ABL-negative MPN patients can be performed at one time within 2 working days, and pathogenic mutations other than JAK2, CALR, MPL can be found, which has a bright prospection in clinic.
