Granular corneal dystrophy is a rare autosomal dominant genetic disease in clinic.Due to the TGFBI mutation on the 5q31 chromosome,the TGFBIp abnormally aggregates in the Bowman layer and the matrix layer and metabolic disorders,patients' bilateral cornea arise opacity,making visual acuity Progressive impairment.At present,there are at least 66 TGFBI mutations,at least 10 of which are related to granular corneal dystrophy,due to variation in genotype and the difference between homozygous and heterozygous,the patients' phenotype shows a significant difference.Along with the improvement of people's cognition,and the application of laser scanning confocal microscope and the gene diagnosis,More and more patients get the correct diagnosis,Current treatment methods mainly include corneal transplantation and laser ablation,patients are not satisfied because of the postoperative recurrence and aggravated.Due to the establishment of granular corneal dystrophy animal model,lithium and gene therapy will show a good application prospects.

Objective To investigate the mechanism underlying the WNK4 kinasemediated inhibitory effect on BK channel. Methods Cos-7 cells were cotransfected with BK in combination with either CD4 (control group) or wild type WNK4 (WNK4-WT).Immunostaining and confocal microscopy,chemiluminescence,Western blotting analysis were then employed to determine the BK localization in cells,BK surface expression and total protein level,respectively.To further investigate whether the reduction of BK protein expression is due to an increase in degradation through a lysosomal pathway,BK protein level was determined after treated with bafilomycin A1(Baf A1),a proton pump inhibitor affecting lysosomal degradation. Results Immunostaining and confocal microscopic study showed that BK was localized both in plasma membrane and cytosol in the control group.After cells transfected with WNK4-WT,BK expression was markedly reduced.Chemiluminescent assay found that BK surface expression level was 299.9±18.6 in the control group,whereas it was significantly reduced (148.4±13.7,P＜0.01) in the WNK4-WT group.Western blotting analysis showed that total BK protein level was markedly reduced in the presence of WNK4-WT compared to the control group.WNK4-WT was shown to significantly reduce the BK total protein level (42.3％±15.2％) compared to the control group (100％) (P＜0.01).When the cells was treated with Bafilomycin A1 (Baf A1,0.5 μmol/L),WNK4-mediated reduction in BK protein was reversed (82.2％±12.1％,P＜0.05). Conclusions WNK4 inhibits total and surface protein expression of BK in Cos-7 cells whick is likely due to an increase in BK degradation through a lysosomal pathway.

Objective To investigatethe role of NF-κB played in the process of the cord blood monocytes differentiating into dendritic cells(DCs)induced by astragalus polysaccharide(APS)and to explore the signal transduction pathway involved in this process.Methods Umbilica]cord blood was collected in aseptic conditions.The cord blood monocytes were obtained by density gradient centrifugation and were divided into three groups afterwards.In the control group.cells were cultivated in the RPMI 1640 complete medium.In the APS group.cells were cultivated in the RPMI 1640 complete medium containing 100 mg/L APS.In the PDTC group:cells were treated with 10 μmol/L disulfide carbamate(PDTC).NF-κB inhibitor in 30 min followed by cultivalion in the RPMI 1640 complete medium containing 100 mg/L APS.,The morphological changes were observed during the process of cultivation by the optical microscope and transmission electron microscopy.Cells were collected 12 d later and the cellular immunophenotyping was assayed by FCM.,The activation and migration of NF-κB fluorescence in the cells was examined by the immunoflouresce microscopy.Results (1)Cells in the control group grown up without cluster forformation and were found fusiform and macrophage-like in 12 d.Cells in the APS group grown up in clnstem,and morphological changes were found from the circular shape to a typical dendritic cells-like shape.Cells in the inhibitor group grown up slowly and without cluster formation,and cell morphdogy had no significant change.(2)The expression of DCs-specific antigen CD80,CD83 and CD86 in the APS group was higher than that in the control group and inhibitom group(P<0.01).The expression of those antigen in the control group and PDTC group was similar and had no statistically significance(P>0.05).(3)NF-κB fluorescence in the nuclei was examined by the immunoflourescence microscopy and was much higher in the APS group than that in khe other groups,especially in 72 h with the activation rate of NF-κB (75.20±7.37)%,while(13.20±3.46)% of PDTC group and(8.20 ±1.92)%,respectively(P<0.01).Conclusion Astragalus polysaccharide can induce the differentiation of umbilical cord blood cells into DCs,and NF-κB is the key component of the signal transduction pathway involved in this process.

Objective To investigate the common types of fetal cardiac malformations and complicated malformations,and to assess the value of classifying on these types.Methods 3201 pregnant women were undergone with fetal echocardiography (FECG),239 fetuses of them were diagnosed to be suffered with congenital heart disease(CHD),and 8 cases were one of twins with abnormal heart confirmed by FECG.All new-births were examined by echocardiography within half year after their births.Results 155 complex CHD in 239 fetuses were diagnosed by FECG,in them the common malformations were in turn 59 cases with diagnosed univentricular heart,29 cases with double outlet right ventricle,19 with atrio ventricular septum defect,12 with tetralogy of Fallot or quinalogy of Fallot,11 with persistent truncus arteriosus,6 with right ventricular dysplasia syndrome,6 cases transposition of the great vessels.100 cases were induced labor,41 of them were comfirmed by pathology.16 fetuses were born,123 cases were being pregnanted or un-followed up.Conclusions Complex and multi-malformation were common in fetal cardiocascular abnormalities.Diagnosing rate of fetal CHD(FCHD) in our enroll fetuses was 7.47 ％,rate of complex CHD vs CHD was 64.85 ％.According different types of FCHD,able to be operated or not after birth,surgery methods,as well as prognosis evaluations,all FCHD cases were classified into three subtypes:curable type,curable palliative type and untreatable type.This newly viewpoint will help pregnant women and their family to make reasonable selection.

Androgen deprivation therapy is one of the main treatments for prostate cancer patients. In recent years, many studies have revealed that androgen deprivation therapy increases the risk of cardiovascular disease, which leads to the cause of death alongside tumor-related deaths. The mechanism may be related to the elevation of testosterone levels, follicle-stimulating hormone levels and unstable atherosclerotic plaque. Standardized cardiovascular disease management in this population is a key issue to improve survival and prognosis. This paper summarizes a management plan covering 5 areas, including history collecting and data examination, assessment, referral, health education, and regimen selection.

Objective To study the effect of different breast milk enhancement strategies and the incidence of complications in premature infants.Method Premature infants whose gestational age less than 34 weeks and birth weight less than 2 000 g were prospectively enrolled from January 2017 to February 2018 at the Department of Neonatology of Huangshi Maternal and Child Health-Care Hospital.According to the odd even number at the end of the hospitalization admission number,participants were assigned into 50～＜70 ml/(kg· d) group and 70～＜90 ml/(kg· d) group,When the children reached the corresponding amount of breast-feeding to be given breast milk fortifier.The demographic information,incidence of complications,rate of weight gain,percentage of extrauterine growth retardation (EUGR) and decrease of Z score at discharge were compared between groups.Result A total of 140 cases were included,with gestational age (31.4±1.9) weeks and birth weight (1 402±213) grams.Among the participants,67 infants were assigned to 50～＜70 ml/(kg·d) group,and 73 infants were assigned to 70～＜90 ml/(kg·d) group.There was no statistical difference between two groups in gender,gestational age,birth weight,length,head circumference,rates of asphyxia,ratio of intrauterine growth retardation,Z score of weight at birth,age at which breast milk fortifiers were added,full enteral feeding time,duration of parenteral nutrition,average length of hospital stay and the time of restoration of birth weight (P＞0.05).The proportion of feeding intolerance in 50～ ＜70 ml/(kg· d) group was higher than that in 70～＜90 ml/(kg· d) group (11.9％ vs.4.1％),the difference was statistical significant (P=0.013).There was no statistical difference in other complications between the two groups (P＞ 0.05).The body weight increase rate of premature infants in 50～＜70 ml/ (kg· d) group was higher than that in 70～＜90 ml/(kg· d) group,and decrease of Z score at discharge in 50～＜70 ml/(kg· d) group was lower than that of 70～＜90 ml/(kg· d),the difference was significant (P＜0.05).Conclusion Adding breast milk fortifier earlier——when the breast feeding amount of 50～＜70 ml/(kg· d)——is more beneficial to the growth and development of premature infants,it also reduces the incidence of EUGR on discharge.However,during the feeding process,it was necessary to be aware of the complications.

From January to July 2017, 872 high-risk middle-aged and elderly patients of stroke who visited general practice clinics in 10 community health service centers in Shanghai were enrolled in the study. Cluster randomization was used to select 427 patients from 5 community centers as the intervention group, and 445 patients from other 5 community centers as the control group. The intervention group received health education and traditional Chinese exercise training on the basis of conventional treatment;while the control group received conventional treatment only. After 12 months of intervention physical examinations and related laboratory tests were performed,and the risk factors were compared between two groups before and after the intervention. The results showed that there were significant differences in the systolic and diastolic blood pressure,blood urea nitrogen (BUN),creatinine (Cr) and homocysteine before and after the intervention in both groups (all P<0.05); and compared the control group the improvement of above indicators was more marked in the intervention group. There was no significant difference in cholesterol, triglyceride, and low-density lipoprotein between the two groups before and after the intervention ( P>0.05). The health management with integrated traditional Chinese and western medicine can effectively control some risk factors of stroke for middle-aged and elderly people, which is beneficial for the prevention and control of stroke in the community.
