Abstract? AlM: To observe the clinical effect of posterior continuous curvilinear capsulorhexis ( PCCC ) in phacoemulsification with posterior capsular rupture.?METHODS: Thrity-eight age-related cataract patients (38 eyes) from March 2013 to October 2013 were selected as experimental group and 50 age - related cataract patients ( 50 eyes ) from March 2013 to October 2013 as control group. ln experimental group, PCCC were used in the intraoperative posterior capsule tears in phacoemulsification. And in control group phacoemulsification was applied. The visual acuity and surgical complications were compared between two groups, the follow-up period was continued to 3mo after operation.?RESULTS: The visual acuity and corneal edema in two groups had statistically significant ( P<0. 05 ) at 1d after operation. Three months after operation, the visual acuity and corneal edema in two groups was not statistically significant ( P > 0. 05 ). At 1d after operation, the intraocular pressure in two groups was not statistically significant (P>0. 05). Three months after operation, the pupil and cystoid macular edema, retinal detachment in two groups was not statistically significant (P>0. 05).?CONCLUSlON:PCCC can improve the therapeutic effect and prevent surgical complications for phacoemulsification with posterior capsular rupture.

AlM: To observe the early tear film changes after trabeculectomy using Keratograph 5M.METHODS:Fourty-one patients (46 eyes) of glaucoma who underwent trabeculectomy were involved. First tear break up time ( FTBUT ) , average tear break up time (ATBUT), non-invasive tear meniscus height (NlTMH), lipid layer thickness and meibomian gland scores were measured at 1d preoperatively and at 1d, 1wk, 1mo postoperatively.RESULTS:At 1d, 1wk and 1mo postoperatively, FTBUT and ATBUT decreased greatly (P<0. 05), as well as lipid layer thickness (P<0. 017). NlTMH at 1d postoperatively increased significantly, but at 1wk and 1mo postoperatively decreased greatly (P<0. 05). There was no significantly difference in meibomian gland scores between preoperation and postoperation (P>0. 05). CONCLUSlON: Keratograph 5M could be used to evaluate tear film function rapidly and accurately. Trabeculectomy significantly alters tear film stability and tear secretion in the short term after operation.

Objective To observe the intervention effect of acupuncture on mammalian target of rapamycin(mTOR)of hypoxic-ischemic encephalopathy(HIE)model in newborn rats.Methods Seven-day-old SD rats were randomly devided into six groups.Sham-surgery group:the bilateral common carotid arteries were separated,without ligation,and the rats were without hypoxia.HIE model group:the bilateral common carotid arteries were separated and ligated,and the rats were in low oxygen.In the sham-acpuncture group,four positions were acupunctured:from Baihui,Dazhui,Quchi and Yongquan by 1 cm after hypoxia ischemia.In acpuncture group,four positions were acupunctured:Baihui,Dazhui,Quchi and Yongquan after hypoxia ischemia,positioned according to the ordinary acupoints for acupuncture in rats.In the antagonists group,the HIE model rats were injected wortmannin 5 μl to the left ventricle.The acupuncture and antagonists group had the same operations of antagonists group and acupuncture group at the same time.All the groups were subdivided into four subgroups in terms of four time periods of 1 d,3 d,7 d and 21 d.The morphological changes of organizational structures of hypoxic ischemia side in brain tissue were observed by pathological methods.The levels of mTOR mRNA expression were detected by RT-PCR.Results In acupuncture group, acupuncture treatment for 21 d showed that acupuncture group had clearly organizational structure,regular arrangements of neurons,normal cell outline,relatively clear nucleolus,mitigated swell neuron and hyperplas-tic glial cells.Compared with that of the HIE model group,acupuncture treatment increased mTOR mRNA dramatically on day 1 ,day 3,day 7 and day 21 (Q =7.099 1 ,9.009 9,7.894 0,9.914 7,P ﹤0.05 respective-ly).The expression of mTOR mRNA in acupuncture and antagonists group was significantly higher than that in sham-surgery group on day 1 ,day 3 day 7 and day 21 (Q =9.868 9,15.843 4,21.007 2,P ﹤0.05 respec-tively).In day 21 ,compared with the sham operation group and the HIE model group,the expression of mTOR mRNA in acupuncture and antagonists group were significantly higher (Q =18.236 0,4.729 7, P ﹤0.05 respectively).Conclusion Electroacupuncture treatment can promote the expression of mTOR at the mRNA level and protect brain of newborn rats with HIE.

Objective To investigate the effect of penehyclidine (PHCD) on Toll-like receptor 4 (TLR4)mRNA and Toll-like receptor 2 (TLR2) mRNA expression in the lung tissue in rats with acute lung injury induced by lipopolysaccharide (LPS) .Methods Sixty healthy SD rats of both sexes weighing 200-220 g were randomly divided into 5 groups ( n = 12 each) :control group (group C) , LPS group and P1-3 groups. Acute lung injury was induced by intraperitoneal (IP) LPS 8 mg/kg in LPS and P1-3 groups. PHCD 0.3, 1.0 and 3.0 mg/kg were given IP after LPS administration in P1-3 groups. The animals were anesthetized at 6 h after IP LPS. Blood samples were collected for determination of serum TNF-α and IL-6 concentrations ( by ELISA) and then sacrificed, the lungs were immediately removed for determination of TLR4 mRNA and TLR2 mRNA expression (by RT-PCR), and microscopic examination. Results LPS significantly increased TLR4 mRNA and TLR2 mRNA expression in the lung tissue and serum TNF-α and IL-6 concentrations. PHCD 1.0 or 3.0 mg/kg significantly inhibited LPS-induced increase in TLR4 mRNA and TLR2 mRNA expression in the lung tissue and serum TNF-α and ILr6 concentrations.The lung histopathologic damage was significantly ameliorated in P2 and P3 groups as compared with group LPS.Conclusion PHCD can protect the lungs against LPS-induced acute lung injury through inhibiting TLR4 mRNA and TLR2 mRNA expression in the lung tissue and reducing the inflammatory response.

AIM:To evaluate the effect of all capsule polishing with polishing mode for decreasing the occurrence of posterior capsular opacification( PCO) .
METHODS: Totally 194 eyes ( 162 patients ) were performed phacoemulsification, posterior chamber intraocular lens were implanted. One hundred eyes were performed with all capsule polishing with polishing mode;94 eyes were performed with the polishing apparatus.
RESULTS:The patients were followed up for 12mo. Six eyes ( 6. 0%) of PCO were found in the 100 eyes with polishing mode group; 15 eyes ( 16. 0%) of PCO were found in the 94 eyes with the polishing apparatus group. The difference was significant (P<0. 05).
CONCLUSION: It can decrease the occurrence of PCO by performing all capsule polishing with polishing mode.

Objective To investigate the correlation between the polymorphism of XRCC2 gene,a DNA double-strand break repair(DDSBR)gene,and the susceptibility to lung cancer in population of North China.Methods By PCR-based restriction fragment length polymorphism(RLFP)technique(PCR-RLFP),a case-control study was performed among 300 patients with lung carcinoma and 300 healthy controls to detect XRCC2(C41657T)polymorphism.Results There was no significant difference in XRCC2(C41657T)allele frequencies between lung cancer patients and healthy controls(P=0.16).The C/C,C/T and T/T genotype frequencies were 72.7%,24.0% and 3.3% in lung cancer patients,and 76.3%,22.0% and 1.7% in healthy controls,respectively.There was no significant difference in C/C and C/T genotype frequencies between cancer patients and healthy controls(?2=0.48,P=0.48).However,the C/T genotype frequency in non-smoke group was significantly higher in lung cancer patients than in healthy controls(?2=6.67,P=0.01).The risk for lung cancer in non-smokers was 2.11 times higher in C/T genotype carriers than that in C/C genotype carriers.There was no significant difference in C/C and C/T genotype frequency between lung cancer patients and healthy controls in the smoke group(P=0.16).Conclusion Overall,there was no significant correlation between genetic polymorphism of XRCC2(C41657T)and the susceptibility to lung cancer.But the C/T genotype might increase the risk of suffering from lung cancer in no-smoking populations of Northern China.
