Objective To investigate the relationship between single nucleotide polymorphisms of surfactant protein C(SP-C)gene and respiratory distress syndrome(RDS)in the Han nationality newborns in Inner Mongolia and whether there is a mutation occurs on SP-C gene exon 4 and 5.Methods One hundred newborns with RDS(case group)and 100 newborns without RDS(control group)were selected.PCR gene analysis was used to establish the genotype and allele frequencies of exon 4 (T138N)and 5 (S186N)on SP-C.Results In the Han nationality newborns of Inner Mongolia region,there was no mutation on SP-C gene exon 4 and 5.Exon 4(T138N)on SP-C could be checked out three genotypes:namely AA,AC and CC.The genetic polymorphisms of exon 4 on SP-C were not statistically different between the case group and the control group(χ2 ﹦0.744,P ﹦0.689).Besides,exon 5(S186N)on SP-C could also be checked out three genotypes:namely AA,AG and GG.The genetic polymorphisms of exon 5 on SP-C were also not statistically different between the case group and the control group(χ2 ﹦0.770,P ﹦0.681 ).Conclusion There is no mutation on SP-C gene exon 4 and 5.The genetic polymorphism of exon 4 and 5 on SP-C displays no signifi-cant correlation with RDS of the Han nationality newborns in Inner Mongolia.

OBJECTIVE To investigate the relationship between HBV DNA and serum IL-18 level in patients with hepatitis B virus. METHODS They were divided by MEIA method into 3 groups. group A:HBsAg+, HBeAg+ and HBcAb +(A); group B:HBsAg+, HBeAb+ and HBcAb+(B); and group C:HBsAb+(as normal controls ). Serum IL-18 level was determined by ELISA method in hepatitis patients and normal controls and HBV DNA was determined continuously . RESULTS Concentration of serum IL-18 in patients with different type of viral hepatitis was significantly higher than those in healthy volunteers(P

OBJECTIVETo study the molecular mechanism of Yangjing Zhongyu Decoction (YZD) n-butanol extracts (ZDC) and ethyl acetate extracts (YSYZ) in reducing androgen in porcine granulose cells by mitogen-activated protein kinase (MAPK) pathway.
METHODSPorcine granulose cells were isolated and cultured. They were inoculated by MAPK inhibitor PD98059 at different concentrations, and then they were divided into the blank control group (0), 1, 3, 10, and 25 micromol/L groups. After 24-h culture the cytochrome P450c17a (CYP17) mRNA expression level was detected using Real-time fluorescent quantitative PCR. Contents of androgen (testosterone) in the supernate were detected using RIA and optimal PD98059 concentration screened. After intervened by 10 micromol/L PD98059 for 24 h, the culture solution was intervened by effective ingredients of with or without YZD or YSYZ at various concentrations (0, 1 , 5, 25, 50 mg/mL) at various time points (3, 6, 18, 24 h). Expression levels of p-ERK1/2, c-Fos and CYP17 were detected by Western blot. Testosterone content in the supernate was determined by radioimmunoassay (RIA).
RESULTSTen pLmol/L PD98059 could obviously decrease p-ERK1/2 protein expression and increase CYP17 mRMA expression, and elevate testosterone content in the supernate (P < 0.05). ZDC and YSYZ at 25 ng/mL could increase p-ERK1/2 protein expression and c-Fos levels, and reduce CYP17 protein expression, and lower testosterone content in the supernate after 6-h intervention (P < 0.01).
CONCLUSIONEffective ingredients of YZD could reduce androgen production in porcine granulose cells through increasing activities of MAPK.

A HPLC method was established to determine the contents of the five anthraquinones and rhaponticin in the different varieties of Rhei Radix et Rhizoma. The difference existed in different varieties. The results showed that rhein and rhaponticin were marker substances which could be used to distinguish palm leaf groups rhubarb and wave leaf groups rhubarb. Authentic rhubarb didn't contain rhaponticin. Falsify rhubarb contains trace amounts of rhein. Rheum tanguticum contains abundant rhein. The ratio value of the content of rhein to chrysophanol could be used to distinguish R. tanguticum from the other two authentic varieties (R. palmatum and R. officinale). The content of rhaponticin varied largely in different varieties of wave leaf groups rhubarb.

Objective To study the correlation between the surfactant protein C ( SP-C) gene mutation in exon 5 area and respiratory distress syndrome(RDS) in premature infants. Methods From January 2013 to January 2015, nonconsanguineous premature infants [28 weeks ≤gestational age(GA)< 37 weeks] of Han ethnicity with RDS admitted to our hospital were selected as the RDS group, and nonconsanguineous Han premature infants without RDS as the control group. SP-C gene exon 5 mutation were detected using the gene sequencing method. Results SP-C gene exon 5 region c. 715G > A heterozygous mutations were detected in 17 cases among 60 patients in the RDS group. The mutation frequency was 28. 3% . SP-C gene exon 5 region c. 715G > A heterozygous mutations were detected in 8 cases among 60 patients in the control group. The mutation frequency was 13. 3% . The mutation frequency in the RDS group was statistically significantly higher than the control group (χ2 = 4. 093,P =0. 043) . In RDS group, c. 715G > A heterozygous mutation had no significant correlation with RDS grades, oxygen therapy, pulmonary surfactant dose nor treatment outcome (P > 0. 05). Conclusions A correlation may be existed between SP-C gene exon 5 area c. 715G > A heterozygous mutation and RDS in premature infants.

The technique introduced in this paper is applied in the endocardial catheter operation, which describes the 3D heart model reconstruction before the operation for the endocardial navigation. After a series of CT images of the thorax are processed, an accurate 3D endocardial model can be reconstructed. At first, the series of 2D CT images are preprocessed for denoising and the enhancement,then they are constructed as the volume data. After the region growing segmentation in the 3D volume data according to the grey value of the voxel in the heart cavity, the heart surface rendering is got and the 3D model of endocardial cavity is reconstructed.
