OBJECTIVETo determine whether the GABA-containing neurons in rat central nucleus of amygdala (CeA) can be activated by acute sodium deprivation.
METHODSAcute sodium depletion was induced by subcutaneous injection of furosemide in rats followed by 24 h of dietary sodium deprivation. The rats underwent 0.3 mol/L NaCl/distilled water two bottle choice test, and the activated neurons were labeled and identified with GABA/Fos-double labeling immunohistochemistry.
RESULTSThe rats with acute sodium depletion exhibited significantly more numerous c-fos-positive neurons and GABA/Fos double-labeled neurons in the CeA than the control group (P<0.01, P<0.05). Consumption of 0.3 mol/L NaCl significantly increased the number of c-fos and GABA/Fos double labeled neurons compared to the distilled water group (P<0.001, P<0.01).
CONCLUSIONGABAergic neurons in the CeA may play an inhibitory role in the regulation of sodium intake in rats with acute sodium depletion.

OBJECTIVETo explore the factors associated with early diagnosis of gastric cancer.
METHODSClinical data were retrospectively analyzed for 250 patients with early-stage gastric cancer (EGC) from 2005 to 2008, during which the concept of intra-epithelial neoplasia (IN) was adopted in our department.
RESULTSOn preoperative endoscopic biopsy with pathological exam, there were 15 cases suspicious for cancer, 90 with high-grade IN (HGIN), and 15 gastric cancer. Postoperative pathological exam of the surgical specimen showed infiltrating early-stage cancer in 224 patients, of which 5 (2.2%) were type I (all were Tsm), 190 (84.8%) were type II including Tm in 82 and Tsm in 108 patients, 29 were type III (5 Tm and 24 Tsm). Twenty-six patients had non-infiltrating lesions (Tis). There were 184 (73.6%) well-differentiated tumors, including 26 Tis, 58 Tm, and 100 Tsm. Lymphatic metastasis was identified in 21 patients, of which 2 (2.3%) were Tm (all were poorly-differentiated) and 19 (13.9%) were Tsm. Lymphadenopathy was present in 15 (7.9%) cases in type II, and in 6 (20.7%) in type III. Of the 90 cases with a preoperative diagnosis of HGIN, 24 were found to be Tis, 29 were Tm, and 37 were Tsm on postoperative pathological assessment.
CONCLUSIONSWell-differentiation is the main histological type in EGC. The adoption of the concept of IN is associated with improved detection of EGC, which warrants further investigation.

Osteogenesis imperfecta is a group of inherited connective-tissue disorders in which synthesis or structure of type I collagen is defective and causes osseous fragility. Type IV osteogenesis imperfecta is dominant inheritance. Here, we report a case of type IV osteogenesis imperfecta family and their female member's pregnancy. Abnormal sonographic findings (marked bowing and shortening of long bones) and family history made the diagnosis of fetus with osteogenesis imperfecta. The parents decided to give up rescuing the infant and a caesarean section at 27 weeks of gestation was implemented. In conclusion, it is possible to make a prenatal diagnosis of osteogenesis imperfecta by ultrasound. For the pregnant women with osteogenesis imperfecta, management decision should be made on an individual basis.

Objective :
To evaluate the immune effects of inactivated H7N9 influenza vaccine.
Methods :
We searched several common databases(The Cochrane Library,PubMed,China Biology Medicine disc,China National Knowledge Infrastructure,etc.)for research articles about immune effects of H7N9 influenza vaccine published from the time the database built to July 10th of 2018,using H7N9 and vaccine as keywords. After screening the articles according to the inclusion and exclusion criteria,we assessed the quality of the studies and then employed seroconversion rate(SCR)as an outcome indicator to analyze the immune effects of different doses and adjuvants.
Results :
We recruited 5 articles on inactivated H7N9 influenza vaccine from 1 679 articles. The sample size was 2 579. The results of the meta-analysis showed that the rate difference(RD)values of SCR in each dose group after the first dose ranged from 1% to 10%,which indicated a poor protective effect;after the second dose of immunization,the RD values of SCR in the vaccines without adjuvants ranged from 13% to 19%,which was not effective enough;the RD values of SCR in the vaccines with adjuvants ranged from 62% to 69%,which met the licensing criteria for influenza vaccine;better results could be achieved when immunized with two doses of vaccines with adjuvants( RR=1.19,95%CI:1.02-1.39);vaccines with AS03 or MF59 at the lowest dose of 3.75 μg had the same immune effects as ones at a dose of 15 μg;vaccines with AS03(RD=89%,95%CI:85%-93%)were superior to those with MF59(RD=42%,95%CI:9%- 75%).
Conclusion
Inactivated H7N9 influenza vaccines could achieve good immune effects when inoculated two doses with adjuvants,and the minimum effective dose was 3.75 μg.

OBJECTIVEDendritic cells an hyperinsulinemia are both implicated in the pathogenesis of atherosclerosis. The aim of this study is to explore the effect of high concentration of insulin on the maturation of monocyte-derived dendritic cells (MoDCs) and related signal transduction pathways.
METHODSHuman monocytes were purified (over 98%) using Anti-CD14 micro-beads and cultured for 5 days with DC Cellgro medium containing rhGM-CSF (100 microg/L) and rhIL-4 (20 microg/L). Immature DC were then incubated with insulin of various concentrations (0, 1, 10, 100 nmol/L) for 24 hours in the presence or absence of LY294002 (PI3K inhibitor) or PD98059 (MAPK inhibitor). Immunophenotypic expression of CD86 and CD83 were detected using flow cytometry. Endocytosis function of the MoDCs was evaluated using FITC-Dextran and MoDCs secretion IL-12, IFN-gamma and TNF-alpha were measured by ELISA.
RESULTSInsulin induced significantly higher CD83 and CD86 expressions on MoDCs in a dose-dependent manner. The endocytosis function of MoDCs were significantly inhibited and cytokine secretions of IL-12, IFN-gamma and TNF-alpha significantly increased by 10 nmol/L and 100 nmol/L insulin. These effects could be blocked by the LY294002 and PD98059.
CONCLUSIONHyperinsulinemia contributed to atherosclerosis via stimulating immune maturation of MoDCs via both PI3K and MAPK pathways.

OBJECTIVETo investigate the efficiency of multiplex ligation-dependent probe amplification (MLPA) combined with short tandem repeat (STR) linkage analysis for the prenatal diagnosis for Duchenne muscular dystrophy (DMD).
METHODSGender of the fetus was first determined by the presence of Y chromosome sex-determining gene (SRY). Subsequently, combined MLPA and STR linkage analysis were applied for the probands, pregnant women and fetuses in 45 affected families.
RESULTSAmong the 45 families, 31 SRY-positive fetuses were identified, among whom six were diagnosed with DMD. For 14 SRY-negative fetuses, four were diagnosed as carriers. The remainders were normal.
CONCLUSIONMLPA can detect mutations in the exons of dystrophin gene, whilst STR linkage analysis can determine whether the fetus has inherited the maternal X chromosome bearing the mutant gene. As the result, the method can detect affected fetuses in which no exonic mutations are detected with MLPA. By combining the two methods, the diagnostic rate for DMD can be greatly improved.

AIMTo study the effect of propylene glycol mannate sulfate (PGMS) on induction of CuZn-SOD.
METHODSWistar rats were given PGMS p.o. at different doses (0, 18.9, 37.8 and 75.6 mg.kg-1.d) for ten days. Then the rats were sacrificed and the total RNA was extracted from the livers. The total RNA samples were loaded on a 1% agarose gel to detect the quality of total RNA. RT-PCR was applied to study the expression of CuZn-SOD mRNA in rat livers. The amplified products were detected by the 1.5% agarose gel electrophoresis. Simultaneously, the CuZn-SOD activities in rat liver were determined by nitrite method.
RESULTSThe total RNA extracted from rat livers was integrated without being decomposed by RNase. The level of CuZn-SOD mRNA of the high-dosage group (75.6 mg.kg-1.d) was higher than that of the control group (0 mg.kg-1.d) (P < 0.01); the CuZn-SOD activities of the high-dosage group were significantly higher than those of the control group (P < 0.001) and the CuZn-SOD activities of the middle- (37.8 mg.kg-1.d) and low-dosage groups (18.9 mg.kg-1.d) were higher than those of the control group (P < 0.01).
CONCLUSIONPGMS can increase the CuZn-SOD activities as well as CuZn-SOD on mRNA level. Therefore, it is possible for PGMS to counteract Atherosclerosis (AS) by inducing the expression of CuZn-SOD.

OBJECTIVETo construct the siRNA eukaryotic expression vectors targeting on TGFβ1, TIMP-1 and TIMP-2 and to investigate the inhibitory efficiency of target genes expression on rat hepatic stellate cell in vitro.
METHODSThe siRNA cDNA sequences of TGFβ1, TIMP-1 and TIMP-2 were designed, synthesized and inserted into plasmid pGenesil-1 respectively to generate eukaryotic expression plasmids. The plasmids were transfected into HSC T6 cells in vitro and the inhibitory efficiency of target genes expression was observed with real-time PCR and Western blot.
RESULTSThe eukaryotic expression vectors were constructed successfully. The expressions of TGFβ1 mRNA, TIMP-1 mRNA and TIMP-2mRNA in siRNA-transfected groups were decreased by 63.4% ± 8.0%, 64.5% ± 9.0% and 55.0% ± 17.0% respectively and the expressions of TGFβ1 protein, TIMP-1 protein and TIMP-2 protein were decreased by 57.8% ± 3.0%, 55.1% ± 5.0%, 49.3% ± 1.0% respectively as compared to the control groups.
CONCLUSIONSThe siRNA eukaryotic expression vectors constructed targeting on TGFβ1, TIMP-1 and TIMP-2 could reduce the expressions of target genes and they might be able to used for the exploration of new anti-fibrosis drugs genetically.
