A retrospective study included 30 cataract cases (30 eyes) with history of vitrectomy. Phacoemulsifica-tion or small incision non-phacoemulsification was performed with vitreous irrigation of 23G TSV. Observe the visual acuities, intraoperative and postoperative complications. Posterior capsule rupture intraoperatively occurred in one patient with phacoemulsification. Three patients suffered intraocular hypotension postoperatively, including one with choroidal detachment, and the other two probably with leakage from incisions. However,the intraocular pressure rised to normal after treatment. Corneal edema and aqueous flare postoperatively occurred in four patients with hard nucleus cataract and three patients with diabetic retinopathy. There were no serious complications occurred in all patients, such as sclera collapse, nucleus sinking into vitreous chamber and bleeding in epichoroidal space. The visual acuities were improved after operation in twenty-eight patients.

Objective To Investigate the relationship between an in sertion (I)/deletion (D) polymorphism for angiotensin converting enzyme (ACE) and A(1166)C Polymorphism of angiotensin type 1 receptor(AT 1R) genes in patients with vertebro basilar insufficiency(VBI). Methods In this study, We examined 120 patients with VBI and 146 normal controls. The genotype for I/D of ACE and A(1166)C of AT 1R was assessed using polymerase chain reaction (PCR) and refrained fragment length polymorphism(RFLP), respectively. Then we compared the genotype frequency distribution among subjects.Results As a whole, there was significant difference in the distribution of ACE (I/I, I/D and D/D) and AT 1R (A/A and A/C), respectively. D allele frequency was higher in patients compared with the normal controls. Our study also revealed that Ⅱ AA and DD AA genotype frequency in VBI was higher than that in the normal controls.Conclusion The D allele for ACE and C(1166) allele of AT 1R may correlated with VBI.Ⅱ genotype for ACE and AA genotype had a positive con influence on the VBI. The affection of DD AA genotype on VBI was negative.

To explore the relationship between brachial ankle artery pulse wave velocity of the (baPWV) in different estimation GFR (eGFR) groups and atherosclerosis.In 2010,2012 and 2014,eGFR and baPWV were detected in 1 427 healthy persons.As eGFR level decreased,baPWV increased accordingly with higher proportion of baPWV ≥1 400 cm/s.The percentage of eGFR lower than 60 ml · min-1 · 1.73 m-2 was similar in subgroups with different baPWV.However,the proportion of eGFR reduction ≥ 30％ decreased according to the elevation of baPWV.Multivariate logistic regression analysis indicated the lower the eGFR,the higher the risk of atherosclerosis.Low eGFR is an independent risk factor for atherosclerosis.

Objective: To investigate the relationship between blood triglyceride (TG) level and brachial-ankle pulse wave velocity (baPWV) in relevant population. Methods: A total of 22622 participants in Kailuan area were enrolled and divided into 4 ranks: Stroke rank, n=5219, Aged rank n=1754, Pregnancy hypertension Rank, n=1561and Peripheral vascular diseases rank, n=14088. All participants finished baPWV examination. The relationship between TG and baPWV was studied by partial correlation analysis, the impact of TG on baPWV was assessed by multivariate linear regression and multivariate Logistic regression analysis. Results: There were 21713 subjects finally enrolled for cohort study and 909 subjects excluded for missing TG information. With elevated TG levels, the average baPWV and the detection rate of baPWV≥1400 cm/s showed the increasing trend. Partial correlation analysis presented that TG level was positively related to baPWV, r=0.235; with adjusted age and gender, TG was still positively related to baPWV, r=0.080. Logistic regression analysis indicated that with other adjusted confounding factors, compared with the first quartile of TG, the second quartile, third quartile and fourth quartile of TG were the risk factors for baPWV≥1400 cm/s, OR=1.161, 95% CI (1.035-1.302), OR=1.312, 95% (1.165-1.476) and OR=1.652, 95% CI (1.463-1.865) respectively. Conclusion: Blood TG level was positively and independently related to baPWV in relevant population.

Objective To study the changes of serum interleukin-8 (IL-8) and interleukin-10 (IL-10) in preterm infants delivered from mothers with chorioamnionitis (CA) and the possible effects on bronchopuhmonary dysplasia (BPD) and brain injury of preterm infants.Method From October 2014 to October 2015,clinical data from mothers without clinical manifestations of CA giving birth to a preterm baby (gestational age:26 to 33 weeks) were collected in Changzhou Maternal and Child Health Hospital and Suzhou Municipal Hospital.The infants were assigned to CA group and non-CA group according to their mother's placenta pathology.The levels of serum IL-8 and IL-10 were measured using enzyme-linked immunosorbent assay (ELISA) on day 1 and day 7,while the levels of WBC,CRP and PCT were measured at birth.The incidences of BPD and brain injury were also reviewed.Result A total of 67 preterm infants were included,with 51 in the CA group and 16 non-CA group.The levels of IL-8 were significantly higher in the CA group than the non-CA group on both day 1 and day 7 [(21.6 ±9.7) ng/L vs.(7.3 ±2.3) ng/L,(26.6 ± 12.9) ng/L vs.(7.3 ± 2.1) ng/L].The IL-10 levels were significantly lower on day 1 [(1.92±0.17) ng/Lvs.(2.04±0.18) ng/L] and higher on day 7 [(2.42±0.60) ng/L vs.(2.03 ±0.18) ng/L] in the CA group.Significant differences existed on the incidences of BPD (54.9％ vs.25.0％) and brain injury (74.5％ vs.43.8％) between the two groups (P ＜ 0.05).The levels of CRP and PCT were higher in CA group (P ＜ 0.05) and the WBC was similar between the two groups (P ＞ 0.05).In CA group,on both day 1 and day 7,infants with BPD had similar IL-8 and IL-10 levels comparing with infants without BPD(P ＞ 0.05),also were infants with brain injury comparing with infants without brain injury.Conclusion Chorioamnionitis in pregnant women may affect serum cytokines levels in premature infants and lead to high incidences of BPD and brain injury.

Objective To explore the relationship between the change in waist circumference (WC) and new onset diabetes (NOD) in a population of north China.Methods A total of 101510 subjects took part in the health examination from 2006 to 2007 for the employees of Kailuan Group.89364 subjects with fasting plasma glucose (FPG) ＜7.0 mmol/L,no history of diabetes,with complete data of FPG and WC,and without taking hypoglycemic agents were sclected as the observation cohort.Subjects who did not participate in the health examination from 2010 to 2011 and had incomplete data were finally excluded and thus 58426 subjects were included for final analysis.According to the baseline WC measurement and its quartile in the health examination during 2006 to 2007,the observed population was divided into two groups (obese group and non-obese group) or four groups ( first,second,third,and forth quartile groups).Multiple logistic regression analysis was used to test the relation between the change in WC and NOD.Results ( 1 ) The incidence of NOD in obese group was higher than that in non-obese group (8.02％ vs 3.37％,P＜0.01 ).Along with increasing WC in the 4 quartile groups,the incidence of NOD was progressively increased,being 2.32％,3.62％,5.46％,and 8.89％ respectively in the total population ( 2.84％,3.65％,5.32％,and 8.95％ in male,and 1.50％,3.41％,6.22％,and 8.51％ in female).( 2 ) Multiple logistic regression analysis showed that compared with the first quartile group,the second,third,and forth quartile groups had increased risks of NOD after adjusting age,gender,and other risk factors,the OR value being 1.17,1.47,and 1.95,respectively.After adjusting above factors in different genders,the influence of the second group on NOD in males and females was not significant,however,they still increased the risks of NOD,with the OR value being 1.08,1.36,and 1.90 in male,and 1.35,1.70,and 1.88 in female,respectively.Conclusion The incidence of NOD is increased with increasing WC.

The level of serum high-sensitivity C-reactive protein (hsCRP) in the population with new-onset diabetes was detected and its influential factors were analyzed.The concentrations of hsCRP increased with age in the population with new-onset diabetes( Ptrend＜0.01 ).The percentage of subjects with hsCRP levels ＞3 mg/L was 18.8％in men and 26.7％ in women.A logistic regression analysis indicated that age,gender,body mass index,waist circumference,fasting plasma glucose,and triglyceride were the influential factors of hsCRP levels in diabetic population( P＜0.05 or P＜0.01 ).A variety of cardiovascular factors affected hsCRP level and a strong association existed between hsCRP and abdominal obesity.

Objective To study the risk prediction for new intracerebral hemorrhage (ICH) with high sensitivity C-reactive protein ( hs-CRP) level. Methods In a retrospective, nested, case-controlled study, 323 cases of ICH were identified and matched with 646 controls. The hs-CRP levels at baseline were compared between the two groups. The relevance of different hs-CRP levels and the risk of ICH were analyzed. Results The ICH group had a higher median hs-CRP levels (1.10 mg/L) as compared with the control group (0. 66 mg/L) with significant difference ( P<0.01 ). In addition, the increase of risk associated with hs-CRP levels was primarily observed in the individuals with the highest quartile of hs-CRP levels(>2.12 mg/L). These patients had an increased risk of ICH (OR 2. 58, 95% CI 1. 77 to 3. 76) as compared with those in the lowest quartile(≤=0.30 mg/L). Individuals with basiline hs-CRP levels above the specified cut point of 3 mg/L ormore and those in the 80th percentile were at a markedly increased risk of ICH (for specified cut point of 3 mg/L,0R2.26, 95% CI 1.60-3.20, P<0.01; for 80th percentile, OR 2.24,95% CI 1.60-3.13, P <0.01, respectively). Conclusions Risk of ICH might be predicted with the level of hs-CRP. With the increase of hs-CRP level at baseline, the risk of ICH was increased.
