Objective To evaluate the long-term effect of phacoemulsification (PHACO)+intraocular lens implantation (IOL) for cataract combined with primary angle closure (PAC) in the expansion phase. Methods Thirty-eight eyes of 29 patients which suffered from cataract combined PAC in the expansion phase had undergone PHACO+IOL and goniosynechialysis from June 2005 to December 2006 were retrospectively studied. Results A total of 32 eyes of 24 cases were followed up for 6 to 35 months post-operatively, meanly 19.53?8.93 months. The intraocular pressure (IOP) was significantly decreased from a preoperative mean of (31.61?9.88) mmHg without medication therapy to (16.73?2.13) mmHg in 1 month after operation and (15.61?1.94) mmHg at the end of follow-up. The differences between the untreatment and the treatment were statistically significant (P=0.000). The best corrected visual acuity (BCVA) was significantly improved in all cases (P=0.000). Although the BCVA at the end of follow-up was declined when compared with the acuity 1 month post-operatively, there was no significant difference. The mean central anterior chamber depth was increased from (2.22?0.51) mm preoperatively to (3.59?0.46) mm in 1 month after operation and (3.17?0.35) mm at the end of follow-up with significant differences (P=0.000). The angle of anterior chamber in all operated eyes became wider and the parts of angle closure opened at different degrees. All of patients had no any vision defection. Conclusion PHACO+IOL and combined with goniosynechialysis blocks primary angle-closure glaucoma course, and has better long-term effect.

Objective To explore the clinical features and operative method of complicated spinal tuberculosis. Methods Totally 562 inpatients suffering from spinal tuberculosis during January 1997 to December 2006 were reviewed retrospectively. A new definition of complicated spinal tuberculosis was made. Complicated spinal tuberculosis was classified into different types. Every type had its special surgical operation approach. Results Among the 87 cases being followed up for 45 months, 75 patients were totally recovered, and 12 patients were obvious improved on the mend according to Dr. Fang Xian-zhi’s standard. The classification of function which above good was 97.1%. The fusion rate was 96.3% during 87 patients who received bone grafting treatment 9 months ago. Posterior convex angle was 24? to 57?, average 35.3?. Conclusion We consider that complicated spinal tuberculosis will not be surgical contraindication. Different types of complicated spinal tuberculosis by different operation approach, and careful preparation before operation will gain good curative outcome.

Objective To analyze the drug therapeutic regimen and duration of the chemotherapy in the spinal tuberculosis in order to determine the best therapeutic regimen and duration of the spinal anti-tuberculo-sis. Methods The medication plan and duration of 890 hospitalized patients with spinal tuberculosis in our hospital from January 2001 to December 2008 were retrospectively investigated. We collected the plan of the initial treatment,retreatment,recrudescence and drug resistance. We also studied the individuation therapeutic regimen of the patients with tuberculosis at other parts or complications. On the basis of these data,we analyzed the interferential appearance that the antituberculosis drug acted on different onsets,manifestations and operations. Results In 890 patients of spinal tuberculosis,596 cases ( 67% ) were initial treatment,294 ( 33% ) were retreatment,recur cases were 110 ( 12. 3% ) ,drug resistance cases were 74( 8. 3% ) ,and those compli-cated with tuberculosis in other parts were 273 ( 30. 7% ) . The main chemotherapeutic regimen was the usual tetragenous protocol ( H12 /R12 /E9 /Z5 /S3) . The retreatment cases were given second-line drugs such as levo-floxacin. The drug resistance cases were also given second-line drugs and intravenous infusion. According to the anti-tubercle bacillus spectrum,individuation treatments were adopted,and the plan was changed in time. The medication duration continued for 9-36 months. All the 890 patients were cured. Conclusion For the treatment of spinal tuberculosis,it is significance to make a efficient and standardized anti-tuberculosis chemotherapy.

0.05). Conclusion The present data suggest that both GG252 and AA804 genotypes of the LTA gene are not the risk factors of MI. Further evaluations in adequately powered large studies are needed to confirm these findings.

Objective To investigate the effect of 17?-estradiol (E2) on the expression of hepatocyte growth factor (HGF) mRNA in the myocardial tissues in rats during myocardial ischemia-reperfusion (I/R) process, and explore the relationship between HGF mRNA expression and myocardial apoptosis. Methods Using the random number table, 40 male SD rats were divided into 2 groups (20 rats in each group) randomly, ischemia-reperfusion (control) group and E2 treatment group. Myocardial I/R models of rats were duplicated by ligating the left anterior descending coronary artery for 20 min then reperfusion for 30 min. The expression of HGF and the apoptosis of myocardiocytes were observed with RT-PCR, TUNEL and flow cytometry. Results At the points of cardiac ischemia for 20 min and reperfusion for 30 min, in the E2 treatment group, the expressions of HGF mRNA were significantly higher than corresponding points of the control group (P

Objective To construct the endothelial cell model with overexpressed human protein kinase C ?2(PKC?2) after high glucose inducement in order to study the function of human PKC?2. Methods The PRKCB1 gene was amplified from pMD18-T-PRKCB1 plasmid and then directly cloned into shuttle plasmid pDC315 to construct shuttle plasmid. Then the recombinant shuttle plasmid and adenovirus genomic plasmid pBHGlox△E1,3Cre were cotransfected into 293 cells to construct recombinant adenovirus Ad-PRKCB1. The virus titer was calculated by TCID50. The Ad-PRKCB1 was verified by immunocytochemistry and RT-PCR. Ad-PRKCB1 was transfected into human umbilical vein endothelial cells (HUVECs) followed by the treatment of high glucose (25 mmol/L) for 96 h, and then the cells were observed by laser scanning confocal microscopy (LSCM). Results Restrictive endonuclease digestion and PCR result showed that the target gene was correctly cloned into shuttle plasmid. Cytopathic effect (CPE) was observed under inverted microscope through homologous recombination. The virus titer was 7.9?109 IU/ml. Immunocytochemical staining and RT-PCR indicated the expression of human PKC?2 in the transfected HUVECs. The translocation was observed under LSCM. Conclusion A recombinant adenovirus vector with human PKC?2 and the endothelial cell model with human PKC?2 overexpression by high glucose are constructed successfully.

Objective To investigate the risk factors of postmenopausal osteoporosis ( PMOP) in Chongqing region,and provide the theoretical basis for osteoporosis prevention and treatment. Methods A hospital-based case-control study was conducted and standardized questionnaire was applied in this project. All patients were informed of the purpose of this study and signed an informed consent form. The protocol and consent form were approved by the Ethics Committee of Third Military Medical University. Non-conditional logistic model was used to estimate the association between risk factors and PMOP. Results After adjustment for some potential confounding factors,multivariate non-conditional logistic regression analysis indicated that family history of hip fracture ( OR = 8. 567,95% CI 3. 463 to 12. 620) ,lower body mass index ( OR = 3. 081,95% CI 1. 344 to 5. 632) ,and parities ( OR = 2. 539,95% CI 1. 263 to 4. 175) were significantly positive correlated with the incidence of PMOP. However,frequently exercise ( OR = 0. 276,95% CI 0. 152 to 0. 730) ,tea drinking ( OR =0. 354,95%CI 0. 209 to 0. 764) and older at menopause ( OR =0. 621,95%CI 0. 327 to 0. 942) were significantly negative correlated with it. Conclusion Family history of hip fracture,lower body mass index and higher parities are the risk factors of PMOP in Chongqing region. Besides,frequent exercise,tea drinking and proper endogenous estrogen level are the protective factors.

Objective To study the relationship between lung inflammation and lung angiotensin Ⅱ ( ANG Ⅱ) in ventilator-induced lung injury ( VILI) and assessed the efficiency of the angiotensin-converting enzyme inhibitor captopril to attenuate VILI in rats. Methods Totally 21 adult male Sprague-Dawley rats were randomly assigned into 3 groups,high-volume,0 positive end-expiratory pressure ( HVZP) group; captopril injection ( 100 mg/kg i. p. ) in 30 min before HVZP ventilation ( HVZP + CAP group) ; no ventilation group ( control) . The blood gas tensions and mean arterial pressure were measured after a polyethylene catheter was placed in one carotid artery and a plastic cannula was inserted into the trachea. The protein contents and contents of macrophage inflammatory protein-2 ( MIP-2) in bronchoalveolar lavage fluid ( BALF) and lung ANGⅡ were determined by ELISA. The changes of lung pathology were observed by HE staining. Results Mean arterial pressure was significantly lower in the HVZP + CAP group than in the HVZP group after 2 hour’s ventilation. Total protein levels were significantly higher in BALF recovered from HVZP-ventilated rats than from controls. BALF MIP-2 and lung ANG Ⅱ were significantly higher in the HVZP group than in the control and HVZP + CAP groups. Lung ANG Ⅱ level was correlated positively with BALF contents of total protein and MIP-2. Conclusion Captopril has the efficiency to attenuate VILI by reducing inflammatory cytokines. Our results suggest that VILI is partly mediated by the local angiotensin system.

Objective To investigate the expression of glucocorticoid receptor ( GR) ? and ? in cultured human keratinocytes ( HaCaT cells) with treatment of dexamethasone ( Dex) and after withdrawal. Methods The mRNA and protein expressions of GR? and GR? in HaCaT cells after the treatment of Dex ( 10 -6mol/L) for 24 and 48 h and in 24,48 and 72 h after withdrawal of Dex were detected by real-time PCR and Western blot analysis respectively. The intracellular distribution of GR? and ? was examined by immunofluorescence. Results In 24 or 48 h after Dex treatment,the expressions of GR? at mRNA and protein levels were reduced in a time-dependent manner ( P

0. 05) . Conclusion Despite immersing in seawater and in freshwater worsen the ALI after open chest trauma,the ALI induced by seawater-immersion is severer than that caused by freshwater-immersion. It is attributed to higher plasma osmotic pressure and abundance of salts after seawater immersion,which increasing the pulmonary penetration index and aggravating the inflammatory response.
