Objective To explore the cataract surgery quality on blindness prevention and postoperative problems in village in short period. Design Population-based survey. Participants 251 cases(254 eyes) received operation and 131 cases(134 eyes)were surveyed 6-month postoperatively. Methods Patients were examined 6-month after the small incision extracapsular cataract extraction and intra ocular lens(IOL) implantation. Examinations were conducted by a special oculist including far vision, near vision, external in- spection, anterior segment, posterior segment, intraocular pressure. Main Outcome Measures Visual acuity, intraocular pressure, diopter, eye complications of surgery. Results Naked far vision of the operated eye more than or equal to 0.3 was 41.8%, naked far vi- sion of the eye more than or equal to 0.05 was 82.8%; corrected far vision more than or equal to 0.3 was 64.2%, corrected far vision more than or equal to 0.05 was 92.3%. Naked near vision more than or equal to 0.1 was 79.9%, corrected near vision more than or e- qual to 0.1 was 85.8%. The main postoperative complications were ametropia, posterior capsule opacification(PCO), deformed pupil, pupil displacement, pigments of IOL, eccentric IOL and intraocular hypertension. The chief reasons of eyes that could not be recovered were vitreous, retina or optic nerve diseases, the key factors that caused living vision less than 0.3 were ametropia, PCO, the disease of vitreous, retina and optic nerve. Conclusions The serious complications affecting the surgery result are limited in a low range. The most important factors of the eye corrected far vision less than 0.05 are the vitreous, retina and optic nerve diseases. In order to improve the visual sight, we should add equipment to calculate the IOL diopter accurately.

Objective To investigate.the survival rates in a follow-up group of patient with primary liver cancer.Methods The follow-up data of new primary liver cancer cases between year 2001-2004 in Xuhui district was investigated.The age distribution of patients was described.Survival rate was analyzed with single and multiple Cox proportional hazards regression model,respectively.Results The age proportion distribution of patients showed double apexes with one in age 45～50 and another in age 70～75.The arithmetic mean of survival month was 16.4 with 95%CI 14.8～18.1 and median month was 6.9.It was no significance between male and female.Patients who had liver operation owned longer survival time,RR=0.315 5(95%CI 0.243 2～ 0.4093).The sutdy showed 5-year survival rate was 40.90%and 3.95%for patients with or without operation,respectively.It had no significant effect on survival time by gender,age and family history.Conclusion The screening test and intervention in high-risk people shall be done preferentially before peak age,so as to find primary liver cancer earlier,and the more patients can accept a suitable surgery care,the more they can obtain longer survival time.

Objective: To observe the clinical efficacy of thunder-fire moxibustion for hypomenorrhea after induced abortion. Methods: A total of 74 patients with hypomenorrhea after induced abortion were randomized into two groups, with 37 cases in each group. The control group was treated with conventional hormone sequential therapy, and the observation group was treated with thunder-fire moxibustion. The course of treatment was 3 menstrual cycles. The traditional Chinese medicine (TCM) symptom scores, menstrual volume, endometrial thickness and the sex hormone levels were observed before and after treatment. The clinical efficacy was compared after treatment. Results: The total effective rate in the observation group and the control group was 91.4％ and 73.5％, respectively, and the difference between the two groups was statistically significant (P<0.05). After treatment, the TCM symptom scores in both groups decreased significantly (all P<0.05), and the scores in the observation group were lower than those in the control group (P<0.05). The menstrual volume, endometrial thickness and each sex hormone level of the patients in both groups were significantly improved after treatment (all P<0.05), and the improvements in the observation group were more significant than those in the control group (all P<0.05). Conclusion: Thunder-fire moxibustion can significantly improve the clinical symptoms of patients with hypomenorrhea after induced abortion; it can increase menstrual volume and endometrial thickness, and regulate the sex hormone levels, producing a better curative effect than the conventional hormone sequential therapy.

Objective To investigate clinical characteristics of refractory systemic juvenile idiopathic arthritis(JIA)and the efficiency of glucocorticoid in therapy on this kind of disease.Methods Thirty-nine children with systemic JIA were divided into low dose group 0.5-1.0 mg/(kg?d)and high dose group 1.0-1.5 mg/(kg?d).And the efficiency was observed by change of active index after 10 and 20 days.Results The effective power was 58.8% and 72.7% after 10 days,respectively.After 20 days,the power was 76.5% and 90.9%,respectively.The power in high dose group was significantly higher than that in low dose group.It had no difference in statistical analysis for efficiency of 2 kind of glucocorticoid dosage to control fever,but it had obvious difference to control arthralgia,arthrocele,erythrocyte sedimentation rate(ESR),C-reactive protein(CRP).Conclusion Glucocorticoid therapy is very effective to control the activity of disease in patients with systemic JIA.

To investigate the clinical efficacy and safety of phototherapeutic keratectomy ( PTK ) in the treatment of bullous keratopathy ( BK) .METHODS: A retrospective analysis of 60 cases ( 60 eyes) of BK patients from Department of Ophthalmology in our hospital October 2011 to July 2014 was undergone. Clinical data of all patients with treatment of PTK were analyzed. Best corrected visual acuity ( BCVA ) , corneal curvature, corneal astigmatism, corneal thickness and corneal endothelial cell density ( ECD ) , postoperative complications before and after surgery were compared. RESULTS: BCVA, corneal curvature, corneal astigmatism of patients before surgery were 0. 05 ± 0. 01 and 37. 02±5. 38, 1. 08±0. 67D, which were significantly less than those of postoperative ( respectively 0. 45 ± 0. 13 and 46. 27 ± 7. 02, 1. 92 ± 0. 73D ), the differences were statistically significant (all P<0. 05). Corneal thickness of patients was 492. 33 ± 18. 27μm before surgery, which was higher than that after surgery 377.27±22.49μm (P<0.05). The difference of visual acuity before and after surgery was statistically significant in this group (P<0. 05). During the follow-up period of 6mo, no recurrence of the original corneal lesions, only 2 cases of postoperative slight haze, it was completely dissipated after given the hormone eye drops.CONCLUSlON: Excimer laser technology has high safety in the treatment of bullous keratopathy, it should be promoted in clinical practice.

Objective To study the effect of injured podocytes on glomerular maturation and its underlying mechanism in neonatal mice.Methods Single i.p.injection with puromycin aminonucleoside (PA,0.1 mg/g BW) was given to ICR neonatal mice at day 1 after birth (1 dpp). Littermates injected with normal saline (NS) were used as control.Animals were examined for urine protein,blood pressure,kidney weight/body weight (KW/BW),renal histology at 2,4,8,12, 30,60 and 90 dpp (n=6～9 for each group).Immunohistochemistry and quantitative RT-PCR were performed to examine the expression of WT-1,CD31,VEGF,Flk-1,Ang-1,Ang-2,Tie-1 and Tie-2.Results Mice with PA injection had lower kidney weight and body weight at all time points as well as lower KW/BW at 4,8,12 dpp when compared with NS controls.Electron microscopy revealed nearly complete foot process effacement and segmental microvillous transformation as early as 1 day after PA injection.PA-injected kidneys showed fewer capillary loops and decreased maturation index as well as less CD31-positive endothelium in cortical glomeruli at 12 dpp. Glomerular mesangial injury and developing glomerulosclerosis along with proteinuria were noted in PA-injected kidneys starting from 30 dpp.Significantly increased systolic blood pressure was detected at 60 dpp in PA mice.Compared with NS injection,PA injection significantly induced decreased mRNA expression of Flk-1 and Tie-2 as well as increased expression of Ang-1,without obvious changes of VEGF at 2 dpp.Conclusions Podocytes in neonatal kidney of ICR mice are susceptible to PA. Such podocyte injury can alter the expression of VEGF and angiopoietin system in glomeruli,leading to abnormal development of glomerular capillaries,and subsequent proteinuria,hypertension and glomerulosclerosis.

Objective To study the effect of different concentration of 1,25-dihydroxyvitamin D3[1,25(OH)2D3] on cell proliferation,differentiation and the expression of vitamin D receptor (VDR) in mouse MC3T3E1 osteoblast.Methods Osteoblast were cultured in medium with different concentrations of 1,25(OH)2D3.Incubated for 48 h,cell proliferation of osteoblast were examined by MTT reduction assay (mono-nuclear cell direc cytotoxicity assay),the osteocalcin (OC) levels in cell medium were detected by ELISA,and the expression of VDR mRNA and protein were examined by using SYBR Green real-time PCR and Western blot,respectively.Results 1.After incubation with 1,25(OH)2D3 for 48 h,the number of MC3T3E1 osteoblast was significantly less than that in control group(P0.05).3.SYBR Green real-time PCR and Western blot results showed that the expression of VDR mRNA as well as VDR protein of osteoblast in 10-8,10-9 mol/L experimental groups were significantly higher than those in control group (Pa0.05).Conclusions Cell proliferation of mouse osteoblast can be inhibited,while the cell differentiation was promoted by 1,25(OH)2D3.1,25(OH)2D3 up-regulated the expression of VDR in mouse osteoblast,which suggested that the VDR signal pathway may play some role in proliferation and differentiation of osteoblast.

Akt1 is a serine-threonine protein kinase that has been implicated in the control of cellular metabolism,survival and growth.Elevated expression of Akt1 has been noted in a significant percentage of human tumors,promoting cellular metastasis.Conversely,some studies have revealed hyperactivated Akt1 inhibited the invasiveness and metastasis of breast cancer cells.To clarify the definite effect of Akt1 on tumorigenesis and development,Akt1 was silenced by RNAi in the highly metastatic murine breast cancer 4T1 cells.Akt1 silencing didn't affect the proliferation of breast cancer cells in MTT assay,while reduced the migration in Transwell assay.Consistent with the above results,Akt1 silencing didn't change the primary tumor weight,but significantly suppressed lung metastasis of 4T1 cells.These observations indicated Akt1 plays an important role in murine breast cancer metastasis,and suggested that Akt1 might be a therapeutic target for breast cancer metastasis.
