Objective To study the hepatotoxicity of cyclosporine-A, tacrolimus and other immunosuppressive drugs in patients with renal transplantation. Methods In 346 cases undergone renal transplantation, ALT, AST, BILT and BILD levels of venous blood 1-90 days after operation, and treatment methods and outcome were reviewed, in order to evaluate the effectiveness of the treatment of hepatotoxicity. Results In CsA group, the occurrence rate of liver dysfunction was 26.9%, in whom ALT, AST and BILD increased apparently (P0.05). In MMF and MRZ group, the incidence of liver dysfunction was almost the same. In 18 cases the drug was changed into FK506, ALT, AST, BILT and BILD all apparently decreased 1 week later (P

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.

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.

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.

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.

OBJECTIVETo investigate the changes in Smad 2, 3, 4 and 7 of the transforming growth factor-beta 1 (TGF-b1)/Smad signaling pathways in carbon tetrachloride (CCL4)-induced hepatic fibrosis rats treated with TGF-b1 small interfering (si)RNA.

METHODSRats were randomly divided among five groups: non-fibrotic (normal); fibrosis-induced (model); fibrotic treated with 0.125 mg/kg TGF-b1 siRNA; fibrotic treated with 0.250 mg/kg TGF-b1 siRNA; and fibrotic treated with negative control TGF-b1 siRNA. The expression of Smad 2, 3, 4 and 7 was detected by real-time polymerase chain reaction (for mRNA), immunohistochemistry and Western blotting (for protein).

RESULTSThe mRNA and protein levels of Smad 2, 3 and 4 were significantly lower in the the fibrotic rats treated with either 0.250 mg/kg or 0.125 mg/kg TGF-b1 siRNA than in the fibrotic model or the negative control TGF-b1 siRNA rats (P less than 0.01). Moreover, the mRNA and protein expression levels of Smad 2, 3 and 4 were significantly lower in the 0.250 mg/kg TGF-b1 siRNA group than in the 0.125 mg/kg group (P less than 0.05). Comparing the 0.250 mg/kg and 0.125 mg/kg TGF-b1 siRNA groups to the model group and the TGF-b1 siRNA negative control group showed significantly increased levels of mRNA and protein expression of Smad 7 (P less than 0.01). In addition, the expression levels of Smad 7 were significantly higher in the 0.250 mg/kg TGF-b1 siRNA group than in the 0.125 mg/kg group (P less than 0.05).

CONCLUSIONsiRNA-mediated silencing of TGF-b1 in rats led to significantly reduced expression of Smad 2, 3 and 4, but significantly increased expression of Smad 7. TGF-b1 regulation of Smad signaling molecules may contribute to hepatic fibrosis in rats and represent a target of future therapeutic intervention.

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.

Objective There is still no specific immuno-therapy to acute respiratory distress syndrome induced by severe trau-ma.The article aimed to investigate the effect of MCC 950 on lung in-jury induced by mitochondrial damage-associated molecular patterns ( MTDs) and preliminarily evaluate its molecular mechanism . Methods 40 SD rats were randomly devided into control group , MTDs group, MCC950 group, MTDs+MCC950 group.The rats were were taken MCC950 (20mg/kg) by peritoneal injection pretreatment for 1 hour, followed by tail vein injection of MTDs (5%liver vol-ume) and were killed 12 hours later.ELISA were applied to detect tumor necrosis factor (TNF-α), interleukin-1β( IL-1β) and IL-18 in broncho-alveolar lavage fluid ( BALF) , and BCA method to assess the content of total protein .Lung tissues were weighed to calculate lung wet weight/body weight( LWW/BW) ratio, and stained by HE staining to observe the pathological changes through light micro -scope.Smith lung injury score was used to assess histological lung injury .Western blot was employed to evaluate the protein expression of Pro-Caspase-1 and Caspase-1. Results ①Compared with control group , TNF-α, IL-1βand IL-18 in BALF of MTDs group were significantly increased( all P<0.05), but not in MCC950 group(P>0.05), TNF-αin BALF of MTDs +MCC950 group were signifi-cantly increased( all P<0.05), IL-1βand IL-18 were not(all P>0.05).Compared with MTDs group, IL-1βand IL-18 in BALF of MTDs +MCC950 group were in serious decline (all P<0.05).Compared with control group, the LWW/BW ratio [(4.19±0.36)mg/g vs (6.32±0.54)mg/g, P<0.05] and the content of total protein [(0.12±0.03)g/L vs (0.79±0.07)g/L, P<0.05] were dramatically increased.Compared with MTDs group, the LWW/BW ratio [(4.35±0.29)mg/g, (4.47±0.0.46)mg/g, P<0.05] and the content of total protein [(0.12±0.06)g/L, (0.15±0.06)g/L, P<0.05] were in serious decline.Smith lung injury score revealed that compared with control group the score of MTDs group was elevated (1.00±0.00 vs 8.33±0.58, P<0.05), and the score of MTDs+MCC950 group was significantly decreased than MTDs group ( 8.33±0.58 vs 3.67±0.58, P<0.05) .Compared with control group , the protein expres-sion of Pro-caspase-1 and caspase-1 were markedly improved (all P<0.05).However, the expression of caspase-1 was significantly milder than that in MTDs group ( P<0.05), the protein expression of Pro-caspase-1 was comparable ( P>0.05). Conclusion MCC950 exerts protective effect against lung injury induced by MTDs probably via the inhibition of NLRP 3 inflammasome activation .
