AIM: To compare the effects of different surgeries in the treatment of angle closure glaucoma with cataract and the improvement of quality of life.METHODS: The clinical data of 60 cases (60 eyes) with angle closure glaucoma and cataract who were admitted to the hospital between January 2014 and October 2016 were collected.According to the surgical method, they were divided into the control group (simple trabeculectomy, n=28) and the observation group (trabeculectomy combined with phacoemulsification and intraocular lens implantation, n=32).The changes of visual acuity and intraocular pressure before and after surgery were compared between the two groups.The incidence of postoperative complications was statistically analyzed, and the quality of life was compared between the two groups.RESULTS: Before surgery, there was no significant difference in visual acuity, intraocular pressure and anterior chamber depth between the two groups (P>0.05).At 4wk after surgery, the visual acuity of two groups increased and intraocular pressure decreased.The anterior chamber depth of observation group increased while that of the control group decreased (P<0.05).At 4wk after surgery, the visual acuity and anterior chamber depth of observation group were higher than that of the control group but intraocular pressure was lower than that of control group (P<0.05).The success rate of surgery and the opening rate of chamber angle after surgery in the observation group were higher than those in the control group (P>0.05).The incidence of postoperative complications in the observation group was lower than that in the control group (P<0.05).Before surgery, there was no statistically significant difference in quality of life score between the two groups (P>0.05).At 4wk and 3mo after surgery, the scores of the two groups increased (P<0.05), and the quality of life scores of observation group were higher than those of the control group at different time (P< 0.05).CONCLUSION: The success rate of trabeculectomy combined with phacoemulsification and intraocular lens implantation is high in the treatment of angle closure glaucoma with cataract.The regimen can improve the visual function, reduce the incidence of postoperative complications, and improve the quality of life of patients.

Objective To evaluate the effect of off-pump coronary endarterectomy (CE) plus off-pump coronary artery bypass grafting (off-pump CABG) on patients with chronic total occlusion (CTO) combined with diffuse distal atherosclerosis. Methods From October 2006 to August 2009,65 CTO patients with 176 angiographically confirmed vascular stenosis or occlusive lesions, 70 of which were complete occlusion, underwent off-pump CABG. During the operation, diffuse intimal thickening distal to occlusive lesion was found, and blood flow of the bridges was unfavorable.Results Therefore endarterectomy was performed, followed by CABG. The blood flow in the bridges were 2-10 ml/min versus 14-37 ml/min before versus after endarterectomy. Pulsatility index (PI) was 5.1-15.6 versus less than 5 before versus after endarterectomy. Left ventricular ejection fraction was also improved significantly [before operation: (0.47±0.12)%, after operation: (0. 52±0.15)%, t=2.17, P＜0.05]. Peri-operative myocardial infarction occurred in 2 cases, but without significant cardiac homodynamic changes. And 23 patients underwent coronary angiography to evaluate graft patency 3-18 months after operation, all of them had favorable blood flow. Conclusions It is feasible to perform off-pump CABG plus coronary endarterectomy for patients of chronic coronary total occlusion combined with diffuse distal atherosclerosis. This treatment is safe and effective.

Objective To investigate the effect of portal hypertension (PH) on the activity of local renin angiotensin system(LRAS). Method The expression of local renin and local angiotensinogen mRNA in liver,splenic artery and vein of PH patients was detected with RT-PCR. Result Expression of local renin mRNA in the liver in control group was 0.19?0.12, significantly lower than that of splenic artery (0.45?0.12) and splenic vein (0.39?0.12) respectively(P

To study ecology suitability rank dividing of the total alkaloid content of Coptis Rhizoma for selecting artificial planting base and high-quality industrial raw material in Chongqing province. Based on the investigation of PCB and DEM data of Chongqing province, the relationship between the total alkaloid content in Coptis Rhizoma and topographical conditions was analyzed by statistical analysis. The geographic information systems (GIS)-based assessment and landscape ecological principles were applied to assess eco logy suitability areas of Coptis Rhizoma in Chongqing. slope, aspect and altitude are main topographical factors that affect the content of the total alkaloid content in Coptis Rhizoma The total alkaloid content in Coptis Rhizoma is higher in the lower altitude, shady slope and bigger slope areas. The total alkaloid content is higher in the south areas of Chongqing province and lower in the northeast. Terrain conditions of the southern region of Chongqing are most suitable for The accumulated of total alkaloid Coptis Rhizoma content.

Objective:To screen the early biomarkers associated with lung carcinoma by using proteomic method. Methods:The proteins of early lung squamous cell carcinoma tissues and adjacent normal tissues were separated by two-dimensional gel electrophoresis (2-DE) and differentially expressed proteins were screened by mass spectrometry (MS). The differential expressions of part proteins were verified by immunohistochemical method. Results:The proteomic profiles of lung squamous cell carcinoma and the adjacent normal tissues were established and the average matched protein spots in the two group were 626 and 602, respectively. Ten protein spots with higher expression in lung squamous cell carcinoma tissues were identified as Annexin 1(Anx-A1),heat shock proteins (HSP27), etc. The proteins were mainly related with cell cycle and signal transduction. The results of immunohistochemistry showed that the positive expression rates of Anx-A1 and HSP27 in lung squamous cell carcinoma tissues were significantly increased (P<0.05). Conclusion:Proteomic technology was an effective method for preliminary identification of the proteins associated with early lung carcinoma. The identified proteins laid a solid foundation for further screening the molecular markers for early diagnosis and treatment of lung cancer.

Lipase gene from Penicillium expansum(lip07) was cloned and over-expressed in Pichia pastoris.a random mutant named ep8,which contained a single amino acid substitution,was obtained by using the lip07 as an error-prone PCR template in previous study.ep8 shows higher thermostability than that of lip07,To further improve the thermostability of the lipase,the Lys of wild-type(lip07) and mutant(ep8) in 202 were substituted by Ala using the Overlap extension PCR technique respectively.The mutant genes(lip07-K202A and ep8-K202A) were subcloned into pAO815,and then transformed into the Pichia pastoris GS115 for extracelluar expression,respectively.15% SDS-PAGE analysis indicated that the molecular mass of PEL-ep8-K202A and PEL-lip07-K202A are both about 28kDa,which is same with the wild-type lipase.The Tm of PEL-ep8-K202A is 41.66℃,2.63℃ higher than that of the wild-type(39.03℃) and 1.21℃ higher than the random mutant(PEL-ep8:40.45℃);the Tm of single mutant(PEL-lip07-K202A) is 37.08℃,2℃ lower than that of the wild-type lipase.

The Monascus mutant with high yield of yellow pigment was obtained by using conventional relevant mutation techniques, e.g., treating with physical mutagens(such as UV light) and chemical sub- stances (such as N-methyl-N'-nitro-N-nitrosoguanidine). The yellow pigment was scanned from 300 nm to 600 nm with UV spectrometer, the maximal absorption was determined at 410 nm. The growth characteristic of Monascus mutant is stable, the yellow pigment value and colour hue in liquid fermentation can reach 100 U/mL and 3.5 respectively. The yellow pigment is stable from pH 3 to pH 8, but the precipitation appeared as the pH of the pigment solution lower than 3.
