·AIM: To study the therapeutic effect of surgical treatment for traumatic cataract.·METHODS: Seventy-three cases(73 eyes) traumatic cataract were performed multi-operation combined cataract extraction, including insertion of a capsular tension ring(CTR), vitreoretinal surgery, ocular foreign body extraction and intraocular lens(IOL) implantation.·RESULTS: Of 73 patients, twenty-seven cases were blunt trauma, while 46 cases were penetrating injuries. Three months after surgery, the final best spectacle-corrected visual acuity(BSCVA) in 5 patients (7%) were 0.05 or less, seventeen(23%) 0.05 to 0.3, while 49(67%) 0.3 or more. There were 93% cases relieved from blindness. Atrophy of eyeball occurred in two cases(3%). Mean follow-up time was 7.8(range 3-15) months.·CONCLUSION: Useful vision can be restored in a proportion of traumatic cataracts after prompt and rational surgical intervention as well as appropriate treatment of sight-threaten complications.

Objective Measuring job satisfaction level of community health workers,providing on the evidences for the design of the relevant policy and the evaluation of job effect.Methods 57 Community Health Service centers and 54 stations were randomly selected in 12 cities in Anhui province,and all staff on the job were investigated.The questionnaires were delivered to the working staff and anonymously filled in by them.Results The total job satisfaction average score of the staff is 110.84± 18.18.The average score of pay(10.05±2.99),welfare(10.35±3.17)and promotion(10.85±3.00)are rather low.The average score of coworkers(14.78±2.11),nature of work(14.60±2.69)and supervision (13.90±3.00)are quite high.Logistic regression analysis shows the staff's duration and title are the main factors affecting their overall job satisfaction.Conclusion The overall job satisfaction level of community health workers is not high.Establishing the reasonable system of pay,welfare mechanism and the predictable promotion space are feasible choices to promote job satisfaction of community health workers

Objective To determine the relationship between subclinical hypothyroidism and asymptomatic myocardial ischemia in type 2 diabetes mellitus.Methods All of 399 asymptomatic subjects who underwent coronary CT angiography with type 2 diabetes mellitus but without thyroid disease were enrolled retrospectively.Totally patients were divided into subclinical hypothyroidism group (17 patients,type 2 diabetes mellitus with subclinical hypothyroidism) and euthyroid group(382 patients,type 2 diabetes mellitus with normal thyroid function).Results The incidence of subclinical hypothyroidism in type 2 diabetes mellitus was 4.3％(17/399).The ratio of male and smoking in subclinical hypothyroidism group was significantly lower than that in euthyroid group (3/17 vs.194/382,P =0.007;2/17 vs.136/382,P =0.043).The incidence of asymptomatic myocardial ischemia in subclinical hypothyroidism group was 5 cases and in euthyroid group was 130 cases,and there was no significant difference(P=0.694).The age,course of type 2 diabetes mellitus,level of glycosylated hemoglobin and low density lipoprotein cholesterol between two groups had no significant difference(P＞ 0.05).Conclusion Subclinical hypothyroidism is not an independent risk factor for asymptomatic myocardial ischemia in type 2 diabetes mellitus.

Objective To study the influence of early intensive blood pressure (BP) lowering treatment on peri-he?matomal secondary neuronal injury and prognosis after acute intracerebral hemorrhage. Methods A randomised con?trolled trial consisting of 36 consecutive patients within 6 h of intracerebral hemorrhage onset were randomly assigned to intensive BP lowering group and guideline BP lowering group. All patients underwent MR spectroscopy at 72 h and were followed up 90 days. N Acetyl Aspartate/Creatine (NAA/Cr) and lactic acid wave around peri-hematomal at 72 h, neuro?logic function at early stage, and death and/or disability at 90d were compared between these two group. Results Spec?trum lines were obtained from thirty-one patients:14 from intensive BP lowing group and 17 from guideline BP lowering group. There was no significant difference in the percentage declines of NAA/Cr at 72 h between the two groups (13.3%± 4.2% vs. 11.9%± 2.8%, P = 0.308). There was no statistical differences either in neurologic function at 7 d or in death and/or disability at 90 d (P>0.05). Conclusions Early intensive BP-lowering treatment had no role on peri-hematomal secondary neuronal injury and prognosis after acute intracerebral hemorrhage. Further high-quality and large-scale ran?domised controlled trial are necessary to verify this result.

Objective To explore the application of three-dimensional (3D) ultrasonography in screening the defects of fetal brain and skull.Methods Thirty-one cases of the fetal were detected in 3D ultrasonography.The ultrasonic data were compared with magnetic resonance imaging(MRI) and pathology.Results Among 31 cases according to 3D ultrasonography,there were 2 of anencephaly, 1 of exencephaly,2 of encephalocele,5 of holoprosencephaly,2 of arachnoidcyst, 1 of vein of Galen aneurysm,2 of agenesis of the corpus callosum, 1 of schizencephaly, 3 of Dandy-Walker syndrome, 7 of ventriculomegaly, and 5 of enlargement of cisterna magna.Compared with the results of MRI,the diagnostic accordance rate was 100% by 3D,it was 93.5% by 2D.Conclusions The structure of fetal brain and skull were viewed more clearly in 3D ultrasonography than 2D ultrasonography and the defects of fetal brain and skull can screened more exactly.

BACKGROUND: The application of adipose derived stromal cells to tissue engineering has been more and more popular around the world. Compatibility of scaffold material is the key point for its further research.OBJECTIVE: To determine the growth rules of rabbit adipose-derived stromal cells with polylactic-co-glycolic acid (PLGA).DESIGN, TIME AND SETTING: An in vitro study was performed at the Institute of Ophthalmology, Otolaryngology Hospital,Fudan University and Shanghai Tissue Engineering Center from September 2007 to March 2009.MATERIALS: Six female New Zealand rabbits aged six months were used for extraction of adipose-derived stromal cells. PLGA was provided by Sigma, USA.METHODS: Adipose tissue was harvested from the nape fat pad of the rabbits following anesthesia. Primary cultured cells were established using type I collagenase and cell cultures were maintained with DMEM containing 10% volume fraction of fetal bovine serum. Cells were passaged when 80% was confluent. The fourth passages of cells were utilized for the study. PLGA consisted of polylactic acid and polyglycolic acid as the ratio of 7:3, and the relative molecular mass was 104900.MAIN OUTCOME MEASURES: Initially, the adherent rate of cells to scaffold was detected. After one week co-culture, the scaffold bearing adipose-derived stromal cells labeled with Dio agent were investigated by fluorescence inverse microscope,scanning electron microscopy and laser scanning microscope.RESULTS: The best adherent rate of adipose-derived stromal cells with PLGA reached 99%. After one-week-incubation in vitro,cells of fiber-shaped or ovule-shaped proliferated well and exhibited stratified growth on the surface of PLGA scaffold. In addition,it also secreted visible extracellular matrices, which could be examined by scanning electron microscopic examination.Meanwhile, the adipose-derived stromal cells grew well and distributed equably inside the PLGA in terms of the investigation with laser scanning microscope.CONCLUSION: The compatibility of adipose-derived stromal cells to PLGA in vitro was well.
