Background Congenital cataract is an important cause of blindness and amblyopia in children,and about 50％ of congenital cataract is hereditary.Objective The aim of this study was to determine the diseasecausing gene of one Hui congenital cataract pedigree by using exon combined target region capture sequencing chip of eye diseases.Methods This study was approved by Ethic Committee of Ningxia People's Hospital and followed Declaration of Helsinki.One Hui congenital cataract pedigree was recruited in Ningxia Eye Hospital in 2011.All the disease history of the members in this family were collected and recorded,and the eye examinations were performed.The peripheral blood specimens were collected from family members and 300 healthy individuals for the extraction of DNA.Exon combined target region capture sequencing chip of eye diseases was used to screen the candidate diseasecausing mutations,then PCR and direct sequencing were used to confirm the disease-causing mutations.Results This H ui family included 61 members of 6 generations,and 18 patients were diagnosed in serial 5 passages,conforming to autosomal dominant inheritance pattern.Among 18 cataract patients,7 individuals were associated with nystagmus and strabismus,and 4 patients had high myopia.Eight candidate pathogenetic mutations were detected by exon combined target region capture sequencing chip of eye diseases and bioinformatics method,with 5 mutations in noncoding regions and 3 in coding regions.The mutation P24T of CYRGD gene was confirmed as pathogenic mutation of this pedigree by using PCR and direct sequencing methods.These mutations co-segregated with affected members of the family,and the mutations were not found in the unaffected family members and 300 unrelated controls.Conclusions P24T of CYRGD gene mutation is confirmed as pathogenic mutation of this pedigree.Exon combined target region capture sequencing chip provides a new approach to detect disease-causing mutations of congenital cataract with diversity clinical phenotypes.

Objective To express recombinant Vp1 protein of chlamydiaphage φCPG1, prepare monoclonal antibody against Vp1 protein and utilize it to screen clinical isolates of Chlamydia trachomatis. Methods The Vp1 protein was obtained by prokaryotic expression, and monoclonal antibody against this protein was prepared by hybridoma technique. ELISA and Western blot were used to identify monoclonal antibodies. Then,the monoclonal antibody was prepared in quantity by injecting hybridoma cells into the abdominal cavity of BALB/C mice, and purified by using protein G affinity chromatography. Clinical isolates of Chlamydia trachomatis were screened for the chlamydiaphage by immumofluorescence assay using the prepared monoclonal antibody.Results Purified Vp1 protein was obtained. The monoclonal antibody against Vp1 protein was gained after 3times of sub-clone and consistently identified as IgG1. Three hybridoma cell strains that stably secreted monoclonal antibody were generated. Chromosome analysis of hybridoma cells showed that the mean number of chromosome was 96, most of them were telocentric and a few were submetacentric. The titer of purified monoclonal antibody was more than 1: 12 800. Twenty clinical isolates were screened by using the monoclonal antibody and no positive results were obtained. Conclusions The monoclonal antibody against Vp1 protein of chlamydiaphage φCPG1 is successfully prepared, while no chlamydiaphage is detected by immumofluorescence assay using the prepared antibody in 20 clinical isolates of Ct.

ABSTRACT:Objective To explore the changes of serum cytokine interleukin-17 (IL-17)in patients with chronic hepatitis B of different clinical types and its clinical significance.Methods We selected 30 cases of mild chronic hepatitis B,34 cases of moderate one,29 cases of severe one,38 cases of liver cirrhosis,and 21 cases of acute on chronic liver failure.Another 30 cases over the same period served as the healthy control group.Cytokine IL-1 7 level in peripheral blood was detected in each group,and all the groups except the control group were detected for liver function and HBV-DNA.These related serum markers were detected and the results were statistically analyzed.Results ① IL-17 in the peripheral blood was (8.103±2.061)ng/mL in healthy control group;(25.551 ±7.078)ng/mL,(45.442±18.358)ng/mL and (75.378±19.05)ng/mL in the groups with mild,moderate and severe chronic hepatitis B;and (97.16±17.066)ng/mL in acute on chronic liver failure group.Its levels gradually increased with the severity;and there were significantly different among the five groups and between every two groups (P<0.01).The peripheral blood level of IL-17 was (8.103±2.061)ng/mL in the healthy control group, (34.517±8.905)ng/mL in compensatory cirrhosis group,and (45.615±15.623)ng/mL in the decompensated cirrhosis group.These three groups had pairwise comparison,and the difference between every two groups was significant (P<0 .0 1 ).The peripheral blood level of IL-1 7 in the decompensated cirrhosis group increased compared with that in the compensatory group.③ In the 1 5 2 cases detected,serum IL-1 7 level and serum ALT,AST,TBIL,HBV-DNA levels were positively correlated,and serum PTA had negative correlation with the level of IL-1 7 .④ In the 2 1 cases of acute on chronic liver failure,the peripheral blood level of IL-1 7 did not significantly differ between antigen-e positive and negative groups (P=0.654).⑤ In 21 patients with chronic on acute liver failure,the level of IL-1 7 in peripheral serum and MELD scores showed a positive correlation by Pearson correlation analysis (r=0.533,P=0.013).Conclusion In patients with chronic hepatitis B,the level of IL-17 in peripheral serum increased with disease severity.Moreover,the level of IL-1 7 in peripheral blood may play a role in promoting the progression of cirrhosis and the development of acute on chronic liver failure.

Objective Gastrointestinal rehydration is a simple and effective method in treatment of burn shock during war-time, fire disaster and other harsh conditions , and practice has proved the exact curative effect of HCO 3 salt sugar liquid .This article was to investigate the effect of pyruvate-enriched oral rehydration solution ( Pyr-ORS ) on intestinal mucosal blood flow ( IMBF ) , activity of Na +-K+-ATPase and intestinal absorption rate during en-teral resuscitation of a 35% TBSA third-degree scald in rats . Methods 90 male rats were randomly divided into 5 groups: scald without fluid resuscitation ( S group ); sham scald resuscitated with HCO3 salt sugar liquid ( SS HCO3 group ); sham scald resuscitated with Pyr-ORS ( SS Pyr-ORS group ); scald resuscitated with HCO 3 salt sugar liquid (S HCO3 group); scald resuscitated with Pyr-ORS (S Pyr-ORS group) (n=18).Each group was divided into 2 subgroups of 1.5 and 4.5 h after scald injury.Intestinal absorption rate of water and Na +, IMBF and activity of Na +-K+-ATPase were detected on each group . Results Compared with shame scald groups , the intestinal absorption rates of water and Na +decreased ob-viously in scald groups with fluid resuscitation (P<0.05);at 1 h after scald injury, the intestinal absorption rates of water and Na +in S Pyr-ORS groups were both higher than those in S HCO 3 groups(P<0.05).Compared with shame scald groups , IMBF and activity of Na+-K+-ATPase at 1.5 and 4.5 h after scald injury decreased obviously in scald groups with fluid resuscitation (P<0.05); at 1.5 and 4.5 h after scald injury, IMBF in S Pyr-ORS groups (95.250 ±5.096/112.765 ±7.215) were greater than those in S HCO3 group (80.764 ±7.852/94.671 ±8.469), which was of statistical significance (P<0.05). Conclusion Pyr-ORS is a simple and effec-tive method in treatment of burn shock during wartime , fire disaster and other harsh conditions .

Background Age-related macular degeneration (AMD) is the main cause of irreversible loss of central vision in old population.The incidence of AMD is increasing year by year,but the mechanism is not clearly understood.Objective This study was to investigate the association between genetic variants and the risk of AMD in Ningxia population.Methods This study was approved by Ethic Committee of Ningxia People's Hospital and complied with the Helsinki Declaration.Written informed consent was obtained from each subject.One hundred and fifty patients with AMD and 145 ethnicity-and gender-matched controls were recruited in Ningxia Eye Hospital from January 2012 to March 2013.All individuals underwent comprehensive eye examinations and genomic DNA was prepared from peripheral blood.The single nucleotide polymorphisms (SNPs) of 8 susceptibility loci in four candidate genes,including complement factor H (CFH),complement factor B (CFB),age-related maculopathy susceptibility 2 (ARMS2) and high temperature required factor A1 (HTRA1),were genotyped with Mass Array and MALDI-TOF technique by Sequenom platform.The distribution of genotype was tested for Hardy-Weinberge equilibrium (HWE).The differences of genotype distribution of allele and haplotype frequencies were compared between patients and controls using chi-squared test and the P value was significant at ＜ 0.006 level after correction of age,and the relationship of genotype distribution with AMD was evaluated by Logistic regression analysis.Measures of linkage disequilibrium (LD) was carried out by Haploview.Results All the genetypes met HWE.Seven SNPs were found to be different in the genotypic distributions and allele frequencies between patients and normal controls (all at P＜ 0.05),however,after Bonferroni correction,the differences of only four SNPs were significant between the patients and controls in the genotype and allele distributions,including the SNPs of rs10737680 and rs1410996 in CFH gene,the SNP of rs10490924 in ARMS2 gene and SNP of rs11200638 in HTRA1 gene.The allele distributions of rs800292 (Pallele =0.006,OR =1.643,95 ％ CI:1.155-2.336) in CFH and rs641153 (Pallele =0.002,OR =0.273,95 ％ CI:0.120-0.620) in CFB were significantly associated with AMD.In addition,five SNPs in CFH gene were consisted of two blocks after analysis by Haploview.In addition,five SNPs in CFH were consisted of two blocks after analysis by Haploview.The first one SNPs (including rs551397 and rs800292) and another one SNPs (including rs12124794,rs10737680) and rs1410996 were in strong linkage disequilibrium (D'=1.00).After 50 000 permutations,the GC and AT haplotypes of the first block and the AAC,TCT and ACT haplotypes in the second block were significantly different between AMD patients and controls (P =0.010,0.010,0.001,0.041 and 0.033,respectively).The allel T of rs641153 was a protective factor of AMD (P=0.002,OR =0.273,95％ CI:0.120-0.620).Conclusions The SNPs rs10737680 and rs1410996 in CFH,rs10490924 of ARMS2 gene and rs11200638 of HTRA1 gene are associated with AMD in Ningxia population.

Background Study determined that retinitis pigmentosa has a similar pathogenesis mechanism to Alzheimer disease,and activity of cyclin-dependent kinase 5 (Cdk5) and its activators participates in the degeneration of central nervous system.Roscovitine,an inhibitor of Cdk5,can suppress activity of Cdk5/p25 pathway and therefore inhibit cell apoptosis.However,the influence of roscovitine on retinitis pigmentosa(RP) is unclear.Objective This study was to investigate the expressions of p35,p25 and tau in the retinas of RCS rats.Methods Roscovitine of 4 μl was intravitreally injected in the right eyes of 12 SPF 17-day-old RCS rats,and the fellow eyes were not intervened as the control eyes.The rats were sacrificed on eighth day (postnatal 25 days) and eighteenth day (postnatal 35 days),and whole retinas were isolated to evaluate the relative expressions of Cdk5,p35,p25 and tau phosphorylation by Western blot,and the activity of Cdk5/p25 was analyzed by quantitative colorimetric assay.The results were compared between the right eyes and fellow eyes by paired t test.The use and care of the rats complied with Ethic Statement of Experimental Animal of Ningxia Medical University.Results In the eighth and eighteenth day after injection,the relative expression values (A values) of p35 in rat retinas were 1.186±0.019 and 1.069± 0.019 in the injected eyes,showing significant decreases in comparison with 1.364±0.016 and 1.214±0.008 of the fellow eyes (t =-6.294,-6.477,both at P＜0.05);the relative expression values (A values) of p25 in rat retinas were 0.312±0.009 and 0.269±0.018 in the injected eyes,which was significantly lower than 0.595±0.013 and 0.473±0.011 of the fellow eyes (t=-36.508,-11.879,both at P＜0.05).No significant difference was found in the relative expression of Cdk5 protein between the injected eyes and the fellow eyes in various time points after injection (both at P＞0.05).The activities of Cdk5/p25 were (0.003 83 ±0.000 14) mol/(s · mg) and (0.002 01 ± 0.000 11) mol/(s · mg) in the injected eyes,with significant decreases in comparison with the (0.005 47±0.000 27)mol/(s · mg)and (0.003 35±0.000 15) mol/(s · mg) of the fellow eyes (t=-9.152,P=0.000;t=-9.248,P=0.000),and the tau phosphorylation levels followed the same pattern in the eighth and eighteenth day after injection (t =-9.854,-6.744,both at P＜0.05).Conclusions Intravitreal injection of roscovitine can inhibit the activity of Cdk5/p25 and tau phosphorylation level in retinas of RCS rats to certain extend.

OBJECTIVETo evaluate its mechanism of inducing the maternal-fetal immune tolerance by studying the effects of Shoutai pills on the expression of Th1/Th2 cytokine and pregnancy in maternal-fetal interface of mice with recurrent spontaneous abortion (RSA).

METHODThe normal pregnancy and RSA model were respectively induced with CBA/J x BALB/c and CBA/J x DBA/2. The mice with RSA were randomly divided into model group and low, middle and high dose groups of Shoutai pills. The mice were killed in 14 days after administration and embryo resorption rate was counted and their decidual and placental tissues were co-cultured to detect the expressions of IL-4, IL-10, IFN-gamma and TNF-alpha with ELISA.

RESULTThe embryo resorption rate of the model group was significantly higher than the normal pregnancy, middle and high dose groups of Shoutai pills could decreased the embryo resorption rate of the mice with RSA (P < 0.05). All the doses in 3 groups of Shoutai pills could decreased the expression of IFN-gamma and TNF-alpha (P < 0. 05) and there was no obvious difference between normal pregnancy group and all groups of Shoutai pills. Middle and high doses of Shoutai pills could increased the expression of IL-4 and IL-10 (P < 0.05) and there was no obvious differences between normal pregnancy and high dose group of Shoutai pills.

CONCLUSIONThe mechanism about Shoutai pills can change Th1 /Th2 cytokine towards Th2 bias, which induced the maternal-fetal immune tolerance.

OBJECTIVETo study the relationship between compliance with anti-hypertension therapy and assessment of quality of health care in hypertensive patients in community.

METHODSAccording to multi-stage cluster random sampling, we selected two communities from 36 streets in certain areas of Shanghai respectively using random number method on May, 2013, 72 communities in total, then we randomly selected 25 patients who were archived in the community health center from each community of the street.We conducted 1 800 questionnaires in total in which 1 172 patients were under medication study. The Morisky Medication Adherence Scale was used to evaluate medication compliance while the Patient Assessment of Chronic Illness Care Scale was applied to measuring the quality of patient's self-reported health service. The Spearman rank correlation analysis was used to evaluate the relationship between assessment of quality of health care for chronic illness and compliance with anti-hypertension therapy. Binary logistic analysis was applied to evaluate the factors which influenced patient's medicine compliance.

RESULTSThere were 567(48.4%) respondents with good compliance. Age less than or equal to 65 accounted for 43.3% (245 people) while age greater than 65 accounted for 56.7% (321 people). The average scores of total and difference dimensions remained at a low level, ranging from 1.97 to 2.67 out of 5. The Assessment of quality of health care score was (2.67 ± 1.33)scores, in which the highest score of the dimensions was patient activation which was (2.56 ± 1.41)scores and the lowest was follow-up / collaboration which was (1.97 ± 1.49)scores. The Spearman rank correlation analysis showed that negative association between accumulate points of patient medicine compliance and patient activation was found (rs = -0.09, P < 0.01). The result of binary logistic analysis indicated that medication adherence of age greater than 65 was 1.49 times (95%CI: 1.11-2.00) higher than age less than or equal to 65. The patient activation was a protective factors of good medicine adherence (OR = 1.35, 95%CI:1.14-1.59).

CONCLUSIONSThe medicine adherence of hypertension patients in community medication compliance is not very good at the moment. The self-rated quality of health care is still relative poor. Positive activation from interaction of physicians and patients can help enhancing patient's medicine compliance.
