Background Congenital cataract is the major cause of blindness in children with plentiful clinical manifestations and closely linked with genetics. Objective Present study was to investigate the classification of congenital cataract in Yunnan province.Methods The manifestation characteristics of 184 eyes of 116 patients with congenital cataract in Yunnan province were analyzed.The relationship of performance of various types of congenital cataract between phenotype and hereditary feature were explored. Results All of the 116 congenital cataract eyes from 116 patients were divided into ten types based on the clinical appearance,including the complete cataract,nuclear cataract,posterior polar cataract,anterior polar cataract,coralliform cataract,coronary cataract,pulverulent cataracts,lamellar cataract and blue cataract.Bilateral nuclear cataract and unilateral entire cataract is most prevalent in these patients.Blue cataract and coralliform cataract belong to the less types.Forty-four in 116 cases were found to have the hereditary history and determined as autosomal dominant inheritance.Sporadic cases were determined in 72 cases.Conclusions The analysis of phenotype of the hereditary congenital cataract offers some clues to the classification of congenital cataract.

ObjectiveTo investigate the role of the anti-podocyte antibody in the pathogenesis of membranous nephropathy(MN).Methods Thirty-six frozen section slice from biopsies of normal kidney were randomly divided into 3 groups:A,B and C groups(n=12,respectively),then,serum of MN and IgA nephropothy patients,and normal saline were added by drops to frozen section respectively,then the changes were observed by fluorescence microscope.Twenty-one male New Zealand white rabbits were feed with standard diet for 1 week,then were randomly divided into 3 groups:D,E,F groups (n=7,respectively),and injected with the serum of MN and IgA nephropathy,and normal saline respectively through ear-border vein.24-h urinary protein, serumalbumin, serumcreatinineweredetected. Atweek8afterinjection, the histopathological changes in kidney tissue of rabbits were observed by light microscope,electron microscope and immunofluorescence staining. Results Immunofluorescenee staining displayed IgG deposition in glomerular podocytes in group A,and there was no positive expression in other two groups.The quantitative measurement of 24-h urinary protein increased significantly after injection of MN serum (P＜0.01),meanwhile the serum albumin markedly decreased (P＜0.01).The inmnunofluorescence staining showed that IgG deposited in the glomerulus capillaries wall,which presented spherical particles.Light microscope revealed the thickening of GBM without nailing process formation.Electron microscope showed the podocyte foot processes,subepithelial dense deposits.Such pathological changes were not found in E group and F group.Conclusion There is anti-podocyte antibody in blood of MN patients,which may play a role in the pathogenesis of MN.

Background Certain relationship has been found between phenotype and genes mutation of congenital cataract.It is clear that different genetic mutations can cause the same complication in congenital cataract,meanwhile,different complications may be caused by the same gene mutation.However,their mechanism is still remained unclear.Objective This study was to observe the phenotype of congenital cataract accompanied with iris dysplasia.Methods Fifteen patients with congenital cataract accompanied with iris dysplasia were included in this study.The slit lamp,gonioscope and ophthalmoscope were used for the examination of the anterior ocular segment,the anterior chamber angle and fundus on all the patients.This study was approved by the Ethic Committee of Second People' s Hospital of Yunnan Province.Written informed consent was obtained from each patient or the custodian prior to any medical procedure.Results All the patients showed binocular involvement.Congenital nuclear cataract with whole coloboma of iris was seen in 7 cases,and 2 cases showed an entire cataract associated with incomplete coloboma of iris.Entire cataract with aniridia was diagnosed in 5 patients,and suture cataract complicated with aniridia was in 1 patient.Conclusions Some regular patterns can be implied between the morphological type of cataract and iris dysplasia,which may be helpful for further study of these diseases.

The article reviewed three aspects of hemiplegic shoulder pain after stroke-introduction, rehabilitation nursing and prospect, in order to provide references for developing effective nursing interventions in the future. We obtained literature from the Cochrane Library, JBI Evidence-based Nursing, PubMed, Wanfang and CNKI Databases between January 2000 and May 2016. According to the principle of three relevant aspects, priority to latest five years and critical appraisal, 39 studies were included. Literature analysis showed that rehabilitation nursing mainly consists of position nursing, supportive devices using, manipulative care and psychological support. Also, it put forward that comprehensive rehabilitation nursing measures have become major means, the combination of Chinese traditional and Western medicine is characteristic therapy in our nation, and nursing practice based on evidence should be set up early to relieve the symptom of hemiplegic shoulder pain and promote quality of life for stroke patients.

The viable but noncuturable (VBNC) state is a survival strategy when bacteria are exposed to en- vironment stress. The VBNC state is part of the life cycle of non-differentiating bacteria, and it has a far-reaching impact on traditional bacteriology. Cells in the VBNC state fail to grow on the routine bacterio- logical media, here its significance in human health and environment science are detailed. Cells entering the VBNC state exhibit dwarfing and a number of metabolic changes in respiration rates and macromolecular synthesis. This paper summarized the variations in DNA and protein comparing to the culturable cells. We also discussed the ability of cells to resuscitate from the VBNC state and return to an actively metabolizing and culturable form. Some new methods for monitoring the VBNC state were listed. Finally the future was suggested.

Objective To study the effects of high matrix metalloproteinase 9 (MMP 9 ) on the biological behaviors of fibroblasts,in order to clarify the possible mechanisms in the wound healing of diabetic foot.Methods Establish the cell model of skin fibroblast with high expression of MMP 9 by high glucose (22.0 mmol/L) and high homocysteine (100 μmol/L) co-culture.Control group was incubated with normal glucose (5.5 mmol/L).Realtime PCR,ELISA and gelatin zymography were used to detect the MMP 9 mRNA,protein expression and activity of MMP 9.Flow cytometry,CCK-8,ELISA assay,scratch test and transwell were used to detect cell proliferation,viability,collagen (hydroxyproline) secretion,horizontal migration and vertical migration of cells.Results Data were expressed as (x- ± s).Differences were considered significant if their P value was ＜ 0.05.Results The expression of MMP 9 mRNA,protein levels and the activity of MMP 9 in high MMP 9 group were 6.05 folds,4.12 folds and 1.58 folds higher than those in control group (P ＜ 0.01,respectively).The proportion of S phase cells,proliferation index,cell viability,collagen (hydroxyproline) secretion,6 h horizontal migration rate and the number of vertical migration cells in high MMP9 group decreased by 29.8 ％,18.1％,23.3 ％,68.7 ％,45.0 ％ and 21.4 ％ than those in control group (P ＜ 0.01,respectively ). Conclusions Fibroblast with high expression of MMP 9 have decreased proliferation,activity,collagen secretion and reduced migration,which suggests that MMP 9 may inhibit the biological behaviors of fibroblasts.

Objective To evaluate the strictness and self-consistency of the charge nurses in the nurses examination using venipunctnre trocar operation as research object.Methods FACETS,the polyhedral Rasch software was used in the examination.Results The strictness and self-consistency of charge nurses were evidently different.Conclusions The variable strictness and self-consistency of the charge nurses in the examination leads to unreliability of the results.Developing a scientific and reliable evaluation system is essential to improve the ability of the teaching nurses and the student nurses as well as the hospital nursing quality.
