AIM:To investigate the efficacy of controlled continuous curvilinear capsulorhexis(CCC) technique in short axial length and shallow anterior chamber eyes.METHODS:Sixty-eight patients(68 eyes) with short axial length and shallow anterior chamber were included.The routine CCC technique was used in 32 cases (32 eyes) and controlled CCC technique was used in 36 cases (36 eyes).The success rate and complication were compared between two groups. RESULTS:The success rate of the routine technique group and controlled technique group was 53. 13% and 86.11% respectively. Incomplete CCC leading to posterior capsule tears was 9.38% and zero in two groups respectively.CONCLUSION: Controlled CCC technique can increase the success rate and reduce complications in short axial length and shallow anterior chamber eyes.KEYWORDS:phacoemulsification; continuous curvilinear capsulorhexis; complication

OBJECTIVETo investigate the placement of a long tube into the small intestine under fluoroscopic guidance and to evaluate its decompression effect on early postoperative small bowel obstruction (EPSBO).
METHODSFifty-four patients with EPSBO requiring decompression between April 2010 and July 2014 were enrolled in the study. Insertion of a long tube was guided by fluoroscopy. We first used the guide wire to pass the pylorus and then used the 10 Fr feeding tube as an exchangeable tube to put the superstiff wire into the duodenum. Finally the long tube could be passed over the guide wire through the pylorus into the intestine. The total procedure time, the radiation exposure time, and the incidence of complications were evaluated.
RESULTSThe long tubes passed into the jejunum on initial insertion for all patients, so the success rate of this technique was 100%. The long tube was inserted into ileum in 18 patients. The mean total procedure time was 34.4 ± 8.6 minutes, and the mean radiation exposure time 18.9 ± 6.8 minutes. A total of 47 patients (87%) experienced full recovery following long-tube decompression and without the need for surgical intervention.
CONCLUSIONSUsing the wire-exchange technique, it is easy to place a long tube into the small bowel under fluoroscopic guidance. This decompression method is safe and effective for management of EPSBO.

A series of novel sorafenib analogues were designed and synthesized. The cytotoxic activities of these compounds were tested in four tumor cell lines. Some of the compounds showed potent antiproliferative activity against the tested cell lines with IC50 = 4-20 micromol x L(-1). Some compounds demonstrated competitive antiproliferative activities to sorafenib against tested cancer cell lines. Among them, compound 7c demonstrated significant inhibitory activities on ACHN, HCT116 and MDA-MB-231 cell lines with IC50 values of 9.01, 4.97, 6.61 micromol x L(-1), respectively.

Objective To evaluate the association between interleukin-I(IL-1)loci polymorphisms and increased risk of gastric carcinoma in samples from northern Chinese population.Methods Blood sam- ples from 126 patients with gastric cancer and 125 controls with chronic gastritis were collected.Genomic DNA was extracted and polymorphisms at -31(C to T),-511(C to T)and at intron 2(86-bp VNTR)of IL-I RN were genotyped by PCR-CTPP,PCR-RFLP and PCR.For detection of Hp infection fast urenase test,~(14)C breath test and serum anti-Hp IgG antibody assay were used.Results Five kinds of polymorphism of IL-IRN were found as 1/1,1/3,1/4,1/2 and 2/2,and the frequencies in patients were 76.19%、4.76%、6.35%、11.90% and 0.79%,respectively.However,the frequencies in controls were 76.00%、4.00%、4.80%、13.60% and 1.60%.No significant differences were observed between cases and controls in each genotype.The polymorphism of IL-IB-31 allele was C/C,C/T and T/T.The frequencies in patients were 12.70% ,47.62% and 39.68%,and in controls 28.00%,48.80% and 23.20% respectively.IL-1B- 31 T/T carriers were at an increase risk of gastric cancer with an odds ratio of 3.772(95% CI,1.786- 7.966).IL-IB-511 alleles were C/C,C/T and T/T.The frequencies in patients were 19.20%,56.80% and 24.00% and in controls,23.38%,49.19% and 27.42% respectively.No significant differences were observed between cases and controls in each genotype.Conclusion In Chinese population,the polymor- phism of IL-1B-31 alleles may be associated with the susceptibility of gastric cancer.However,no evidence was found to support that the polymorphisms of IL-1RN and IL-I B-511 alleles had relationship with gastric cancer.

Objective To investigate the effect of optimizing protocol activity on the cardiac function in patients with hypertension.Methods One hundred and one patients with mild and moderate hypertension in Navy General Hospital were enrolled in the study.The patients took regular exercise(6 min walking activity and treadmill test),Echocardiogram was performed 24 h after 6 min walking activity and treadmill test.The cardiac function related parameters were obtained through M-mode,2DE,pulse Doppler and DTI detection to compare the effect of 6 min walking activity and treadmill test on cardiac function.Results The results showed that in the male hypertensive patients,EF and E/E' after treadmill test were superior to those after 6 min walking activity (EF:(59.33±4.46)% vs.(56.05±4.57)%;E/E':(4.12±1.66)vs.(4.95±1.79)),the differences were statistically significant(P=0.02,0.01),while among the female hypertensive patients,there were no significant differences in cardiac function(P>0.05).Conclusion Appropriate activity can improve the cardiac function in male hypertensive patients.EF and E/E' after the treadmill test performed better than those after the 6 min walking activity,while its influence on female hypertensive patients was not significant.

A series of 2-(3-butynoicamidophenyl)benzothiazole derivatives were synthesized starting from 4-fluoro-3-nitrobenzoic acid. Structures of all the synthesized compounds were confirmed by 1H NMR and HR-MS. Their antitumor activities against human tumor cells lines (HCT116, Mia-PaCa2, U87-MG, A549, NCI-H1975) were evaluated by MTT assay. The results revealed that most of the synthesized compounds showed potent activities against HCT116, Mia-PaCa2, U87-MG tumor cells lines. Particularly, compounds 14c and 14h exhibited better activity with IC50 values of 1 x 10(-8) mol x L(-1) against U87-MG and HCT116 respectively. The structure-activity relationship of compounds was also discussed preliminarily.
