AIM: To observe the effect of intraocular lens ( IOL) implantation on visual acuity and contrast sensitivity in patients with cataract.
METHODS: Fifty - eight cases ( 72 eyes ) cataract patients with regular cornel astigmatism, in our hospital from May 2014 to May 2015 were randomly divided into two groups to undergo phacoemulsification and IOL implantation: the observation group: 29 cases (36 eyes) received multifocal toric IOL implantation; the control group: 29 cases (36 eyes) received monofocal toric IOL implantation. Uncorrected distance visual acuity ( UCDVA), uncorrected near visual acuity ( UCNVA), best corrected distance visual acuity (BCDVA), the best corrected near visual acuity ( BCNVA ), total eye astigmatism, and the dark contrast sensitivity were observed for these patients at 1 and 6mo after cataract surgery.
RESULTS: There were no statistical significant difference between the two groups at postoperative 1, 6mo on UCDVA, BCNVA, BCDVA and total eye astigmatism(P>0. 05). UCNVA of observation group at 1 and 6mo were better than those of control group ( P <0. 05); there were statistically significant difference in high frequency comparison at the sixth postoperative months (P<0. 05).
CONCLUSION: Both monofocal toric IOL implantation, and aspheric multifocal toric IOL implantation for cataract with regular corneal astigmatism are effective to improve visual acuity. But the latter treatment would contribute to the improvement of uncorrected near visual acuity and the dark contrast sensitivity.

Objective:To analyze the risk factors of non-alcoholic fatty liver disease (NAFLD) among elderly residents in the community.Methods:A total of 1 894 patients aged 60-75 years with NAFLD visiting general practice clinic from March 2016 to March 2018 were enrolled in the study; 1 894 age and sex-matched subjects without NAFLD served as the control group. The data of gender, age, smoking status,body mass index (BMI), waist circumference, blood pressure, blood biochemistry,past medical history and other clinical and laboratory testing were collected in the two groups. Multivariate logistic regression analysis was performed to explore the related risk factors of NAFLD.Results:The BMI [(27±3) kg/m 2vs.(24±3) kg/m 2, t=-26.139], waist circumference [(89±8) cm vs.(82±8) cm, t=-24.398], heart rate [(75±11) bpm vs. (74±11) bpm, t=-2.370], and diastolic blood pressure [(87±10) mmHg vs. (85±10) mmHg(1 mmHg=0.133 kPa), t=7.898] in the NAFLD group were significantly higher than those in the control group(all P<0.05). The levels of fasting blood glucose (FBG) [(5.9±2.0)mmol/L vs. (5.3±1.5) mmol/L, t=10.438], glycated hemoglobin (HbA1c) [(6.2±1.2)% vs. (5.9±0.9)%, t=11.654], alanine aminotransferase (ALT)[(24±16) mmol/L vs. (18±15) mmol/L, t=11.915], aspartate aminotransferase (AST) [(23±11) mmol/L vs.(22±13) mmol/L, t=4.300], blood uric acid (UA) [(342±84) mmol/L vs. (307±80) mmol/L, t=13.189], total cholesterol (TC) [(5.3±1.1) mmol/L vs. (5.1±1.0) mmol/L, t=6.073], triglycerides (TG)[1.71(1.29,2.35) mmol/L vs. 1.17 (0.91,1.57) mmol/L, Z=37.261], and low-density lipoprotein cholesterol (LDL-C)[(3.4±0.9) mmol/L vs. (3.2±0.9) mmol/L, t=6.984] in NAFLD group were significantly higher than those in the control group (all P<0.01); and the levels of blood creatinine (Cr) [(70±17) mmol/L vs. (71±18) mmol/L, t=-2.712] and high-density lipoprotein cholesterol (HDL-C) [(1.3±0.3) mmol/L vs. (1.5±0.4) mmol/L, t==-16.726] in NAFLD group were significantly lower than those in the control group (all P<0.01). The proportion of people with hypertension [53.8% (1 019/1 894) vs. 43.4% (822/1 894)], type 2 diabetes [16.7%(317/1 894) vs. 11.3%(214/1 894)], metabolic syndrome [48.3% (915/1 894) vs. 18.0% (341/1 894)] in NAFLD group was significantly higher than that in the control group (χ 2=41.013, 23.237, 392.446, P<0.01). Logistic regression analyses revealed 13 independent risk factors of NAFLD, including 60-75 years-old female ( OR=2.348, 95 %CI: 1.917-2.876, P<0.01), high BMI ( OR=1.143, 95 %CI: 1.099-1.189, P<0.01), elevated TG ( OR=1.894, 95 %CI: 1.716-2.090, P<0.01), LDL-C ( OR=3.066, 95 %CI: 2.359-3.983, P<0.01) and HbA1c ( OR=1.276, 95 %CI: 1.175-1.386, P<0.01). Conclusion:The factors associated with NAFLD are complicated; and corresponding measures targeting the risk factors should be taken to reduce the occurrence and development of NAFLD among elderly people in the community.

Bacteria isolated from rotten hides,one identified as Pseudomonas aeraginosa later, were shown to decompose fresh hides completely in 48 hours at room temperature. Strongly collagenolytic activity was detected when native collagen from calfskin was used as substrate. The optimal reaction pH value and temperature of the collagenace produced by P.aeraginosa are 7.5 and 32℃ respectively. EDTA and EGTA inhabit the collagenolytic activity severely while PMSF has little effect on it. Not only media components but also fermentation conditions have differents effect on the production of this collagenolyic enzyme.

AlM:To evaluate the efficacy of combined pranoprofen eye drops and artificial tears on the treatment of mild to moderate dry eye syndrome after trabbeculectomy.METHODS:This prospective case control study included 63 cases (63 eyes) of patients with mild to moderate dry eye syndrome after trabbeculectomy in our hospital from November 2013 to June 2013. All subjects were randomly divided into two groups. Observation group was treated with combined pranoprofen eye drops and artificial tears and control group received simple artificial tears marking the eyes at 1, 2, 4wk. The patient's symptoms, signs, BUT, S▏t, and FL were observed before treatment and 1, 2, 4wk after treatment.RESULTS: After 2wk, the symptoms of observation group were improved, there was statistically significant difference (P<0. 05). FL difference of each group was statistically significant ( P<0. 05 ); After 4wk, symptoms and signs were improved. There was statistically significant difference ( P < 0. 05 ). The BUT of the observation group and corneal FL scores of two groups showed significant differences (P<0. 05). CONCLUSlON: Artificial tears joint pranoprofen eye drops has good curative effect in the treatment of mild to moderate dry eye syndrome after trabbeculectomy.

Objective To study the expression of membrane glucocorticoid receptors(mGR), the correlation between mGR and glucocorticoid(GC)'s effects on apoptosis and proliferation of peripheral blood lymphocytes(PBLs) in minimal change nephrotic syn-drome(MCNS)and the influence of GC on mGR. Methods MCNS, nonminimal change NS(NMCNS) and healthy children were involved in this study. Indirect immune fluorescence and flow cytometry were used to examine the percentages of positive mGR lymphocytes; the apoptosis of PBLs was measured by propidium iodide(PI) staining and the proliferation of PBLs was investigated by fa -TdR incorporation. Results 1.mGR expression in MCNS was higher than that in NMCNS and healthy control,but it was reduced after clinical GC therapy(P

Objective To compare the complete ablation rate of radiofrequency (RF) ablation and high-intensity focused ultrasound (HIFU) in the treatment of uterine ifbroids with different blood supply. Methods One hundred and ten patients with 146 uterine ifbroids in Xijing Hospital of the Fourth Military Medical University from January 2009 to December were randomly divided into two groups and treated with HIFU or RF respectively. Each group had 55 patients. All patients were examined by color Doppler lfow imaging before the treatment. The blood supply of ifbroids were semi-quantitatively classiifed into three grades including G1, G2 and G3. The HIFU group had 15 patients with 20 ifbroids in which blood supply was G1, had 32 patients with 38 ifbroids in which blood supply was G2, and had 8 patients with 10 ifbroids in which blood supply was G3. The RF group had 14 patients with 18 ifbroids in which blood supply was G1, had 31 patients with 42 ifbroids in which blood supply was G2, and had 10 patients with 18 ifbroids in which blood supply was G3. The complete ablation rates of the two treatments were evaluated by contrast-enhanced ultrasound one week before and after treatments. Fibroids which had no contrast agent perfusion and smooth boundary were completely ablated. Statistical analyses were used to compare the complete ablation rates and postoperative complications rates of these two methods. Results When ifbroid′s blood supply was G1, the complete ablation rate was 80.0%(16/20) and 88.9%(16/18) in HIFU and RF group, respectively. The difference was not statistically signiifcant (χ2=0.563, P>0.05). When ifbroid′s blood supply was G2 and G3, the complete ablation rate in HIFU and RF group was 90.5%(38/42) vs 55.3%(21/38) and 72.2% (13/18) vs 20.0% (2/10), respectively. There was statistically difference between these two groups (χ2 =12.778, P < 0.05;χ2=7.049, P < 0.05, respectively). Postoperative complications included fever, abdominal pain, pelvic effusion and vaginal discharge and unilateral lower limb numbness. The incidence of complications was lower in HIFU group than that in RF group, which was 9.1%(5/55) and 27.3%(15/55) respectively, This difference was statistically signiifcant (χ2=6.111, P<0.05). Conclusions HIFU and RF are both effective in treating uterine ifbroids with few blood supply. However, RF can be more effective than HIFU in treating hypervascular ifbroids. Therefore, RF might be able to apply to majority of the ifbroids. As a non-invasive therapy, HIFU is more suitable for hypovascular ifbroids and could be the ifrst therapy in clinic.
