To evaluate the influence of phacoemulsification on corneal endothelium of senile cataract with lupus nephritis (LN).
●METHODS:This clinical trial involved 40 cataract patients with lupus nephritis (40 eyes), and 50 cases (50 eyes) without lupus nephritis. All of them underwent phacoemulsification+lOL implantation. The parameters of corneal endothelial cell including central corneal endothelium cell density ( CED ), average area of endothelial cell ( AVE) and coefficient of variation ( CV) were recorded by corneal endothelial microscope pre -operation and at one month after operation. The data were analyzed by SPSS 13. 0 statistical software.
● RESULTS: Both LN group and control group, the morphology of coneal endothelial was statistical significant differences between pre - operation and 1mo postoperation. The CED was lower, AVE and CV were higher ( P < 0. 05, respectively). A significant decrease in CED was seen in the LN group than did in the control group (P < 0. 05). Compared to control group,the post -operative AVE and CV in LN group was significantly increased (P<0. 05).
● CONCLUSlON: The corneal endothelial cell in lupus nephritis patients is more fragile. Safe and reliable operation should be selected for these patients.

Objective To investigate the role of nerve growth factor (NGF) in the pathogenesis of diabetic neuropathy (DNP) and the correlation of NGF level with,sensory nerve conduction velocity (SNCV) and duration of DNP.MethodsThe 41 patients with DNP,35 diabetics without DNP and 33 healthy controls were enrolled.And the serum level of NGF was measured with ELISA,the SNCV of left medial nerve,ulnar nerve,peroneal nerve and tibial nerve were measured too. Then the correlation analysis was completed. ResultsThe serum level of NGF was significantly lower in DNP patients [(665.18±188.32) ng/L] than in healthy controls [(976.44±159.07)ng/L] and in diabetics without DNP [(943.32±167.33) ng/L,F=9.316,P<0.001].The NGF level of DNP patients was positively correlated with SNCV of left medial nerve (r=0.810,P<0.001 ),left peroneal nerve (r=0.760,P<0.001) and duration of DNP (r=0.542,P<0.001).Conclusions The serum level of NGF is lower in DNP patients than in healthy controls.The decrease of the production of NGF may play a role in the pathogenesis of DNP.

Objective To investigate the relationship between lower limb artherosclerosis and cardiac function in elderly patients with diabetes mellitus(DM)complicated with coronary heart disease (CHD). Methods 441 cases of elderly patients were divided into four groups: the group with CHD (n=117), the group with DM(n=42), the group with DM compllicated with CHD( DM±CHD, n=132),the group without DM and CHD(NC,n=150). Systolic blood pressure (SBP), diastolic blood pressure(DBP), pulse pressure (PP), braehial-ankle pulse wave velocity (baPWV), ankle-brachial index(ABl) and toe-brachial index(TBI) were measured by the auto-survey artherosclerosis apparatus.Left ventricular posterior wall (LVPW), left atrium (LA), fractional shortening (FS), ejection fraction(EF) and EF slope were measured by the two-dimensional echocardiography. Results The baPWV was significantly higher in DM+CHD group than in DM group and NC group[(20125±354)cm/s vs (1849±467)cm/s, (1863±347) cm/s. P<0.05]. The ABI was significantly lower in DM±CHD group compared with NC, CHD and DM groups (0.91±0.23 vs 1.15±0.11,1.07±0.16 and 1.06±0.14. all P＜0.05). There were significant differences in TBI among four groups(all P<0.05) :NC group(0.905±0.15)>CHD group(0.805±0.16)>DM group(0.71±0.17)>DM+CHD group(0.625±0.17). The LA and the LVPW were significantly higher in DM+CHD group than in NC group(P<0.05). The FS and EF slopes were significantly lower in the DM+CHD group than in DM group (P<0.05) and NC group(P<0.05). The EF in DM+CHD group was significantly lower than that in other three groups (P<0.05). BaPWV showed a strong negative association with FS,EF and EF slope(r:-0.112,-0.151,-0.275. all P<0.05). ABI showed a strong positive association with FS,EF and EF slope(r:0.150,0.186,0.260. all P<0.01) ,TBI was found to have strong negative association with LA and LVPW ( r:-0.158,-0.171;all P<0.01) and have strong positive association with FS,EF and EF slope(r:0.163,0.197,0.243.all P<0.01). Conclusions The lower limb artherosclerosis is serious and cardiac function is significantly decreased in elderly patients with diabetes mellitus complicated with coronary heart disease. PWV,ABI and TBI are closely related with cardiac function and can reflect the state of cardiac function in some extent.

Objective To evaluate the relationship of central aortic pressure (CAP) with atherosclerosis and left ventricular function in elderly patients with essential hypertension. Methods A total of 155 elderly hypertensive patients were divided into two groups: aged 60-79 years group (n = 71) and aged 80-95 years group (n= 84). Central aortic waveforms were generated using pulse wave analysis, then CAP and augmentation index (AI) were determined. Auto-survey atherosclerosis apparatus was applied to examine brachial-ankle pulse wave velocity (baPWV), ankle-brachial index (ABI) and toe-brachial index (TBI). Interventricular septal thickness at end diastole (IVSd), left ventricular end-diastolic dimension (LVDd), left ventricular posterior wall thickness at end diastole (LVPWd), relative left ventricle thickness (RLVT), left ventricular mass index (LVMI), Ejection fraction(EF) slope, left ventricle ejection fraction (LVEF) and fractional shortening (FS) were measured by the two-dimensional echoeardiography. Results Systolic pressure (SBP), pulse pressure (PP), CAP, AI and baPWV were significantly higher in aged 80-95 years group than in aged 60-79 years group (all P<0.05), ABI and TBI were significantly lower oppositely (both P<0. 01). IVSd, LVPWd, RLVT and LVMI were all significantly higher and EF slope was lower in aged 80-95 years group than in aged 60-79 years group (all P<0. 057. There were no significant differences in LVDd, LVEF and FS between the two groups (both P>0. 05). CAP had positive association with PP, AI and baPWV (r=0. 505,0. 284,all P<0.01). After adjustment for age, gender, smoking, body mass index, fasting blood sugar, creatinine, uric acid, cholesterol, triglyceride, low-density lipoprotein cholesterol and high-density lipoprotein cholesterol, there was no significant relationship between CAP and ABI or TBI (both P>0. 05). There was also positive association of CAP with IVSd, LVPWd, RLVT, LVMI, while negative associations of CAP with EF slope (all P<0. 01). There were no significant relationship between CAP and LVEF, FS, LVDd (all P> 0.05). Conclusions CAP and degree of artherosclerosis increase with aging in elderly patients with essential hypertension, which contributes to left ventricular hypertrophy and the decreased diastolic function. CAP helps to make an early diagnosis of or screening arteriosclerosis, and it is an important forecast factor for cardiovascular disease.

Objective To investigate the changes of serum ferritin and homocysteine of diabetic patients,to explore its correlation with diabetic gastroparesis.Methods Pure 50 patients with diabetes,50 patients with diabetic gastroparesis,and 50 cases of normal control group were chosen.The serum ferritin levels were measured with chemiluminescence method,the serum homocysteine levels were measured with enzyme linked immunosorbent assay (ELISA) method.The changes of serum ferritin and serum homocysteine in each groups were observed.Its relationship with diabetic gastroparesis was studied.Results For all diabetic patients,the serum ferritin and homocysteine levels were significantly higher than those in normal control group (P ＜ 0.01).Patients with diabetic gastroparesis was higher than those of pure diabetes (P ＜ 0.01).Serum ferritin levels was positively correlated with glycosylated hemoglobin and homocysteine (r =0.62,0.78,P ＜ 0.01).Multi-factor analysis showed that serum ferritin,and homocysteine level was positively associated with diabetic gastroparesis (P ＜ 0.05).Conclusions The increases of serum ferritin and homocysteine levels were closely related to the occurrence and development of diabetic gastroparesis.They can be used as one of parameters of diabetic gastroparesis,and provide theoretical basis for clinical intervention therapy.

To investigate the effects of human anti-BAFF scFv-Fc against the hsBAFF, ICR mice were randomly divided into six groups: control, hsBAFF (1 mg x kg(-1)), hsBAFF (1 mg x kg(-1)) + Ab (1 mg x kg(-1)), hsBAFF (1 mg x kg(-1)) + Ab (2 mg x kg(-1)), hsBAFF (1 mg x kg(-1)) + human IgG (1 mg x kg(-1)) and hsBAFF (1 mg x kg(-1)) + human IgG (2 mg x kg(-1)) groups. The effects of scFv-Fc administration on the proliferation of B lymphocytes were evaluated using an MTT assay. The titres of antibody in the serum and B lymphocytes differentiation were assessed by ELISA and flow cytometry, respectively. The results showed that administration of scFv-Fc to mice injected with hsBAFF significantly prevented human BAFF-induced increases in splenic B cell numbers and serum immunoglobulin levels. Furthermore, this fully human antibody would avoid inducing the human anti-mouse antibody (HAMA) response when used in humans. These findings suggest that the compact antibody may be useful in therapeutic or diagnostic application of the BAFF-associated autoimmune diseases in human.

To investigate the gene typing, molecular characteristics of virulence and resistance associated gene of Clostridium difficile from clinical isolates in China, the genes tcdA,tcdB of toxin A and B, cdtA,cdt B of binary-toxin, and erm B of clindamycin resistance were detected by conventional PCR. Genotyping of toxic C. difficile were conducted by means of analysis of 16s-23s internal spacer region polymorphism with PCR assay. Then the antibiotic resistance of toxic C. difficile to ampiciline, clindamycin, metronidazole and vancomycin was conducted with E-test. It was found that 8 toxic C. difficile strains were demonstrated out of 12 clinical isolates, in which 5 strains were tcdA+ and tcdB+, and 3 strains tcdA- and tcdB+, accounting for 62.5% and 37.5% respectively. Binary-toxin genes detection were negative in all the strains. Clindamycin resistance associated gene ermB was positive in 4 out of 8 toxic C. difficile strains, accounting for 50%. 8 toxic isolates were typed into 4 gene types, the dominant type was ZR I,accounting for 62.5%. Resistance rate of 8 toxic C. difficile strains against ampiciline(AC), clindamycin(CM), metronidazole(MZ) and vancomycin(VA) was 37.5%,87.5%,12.5%, and 0 respectively. No isolates belonged to ribotype 027 or 078. Isolation rate of toxic C. difficile is high to 66.7%. There is obvious gene polymorphism in clinical isolates of Chinese toxic C.difficite, and ZR I is preponderant genotype in 4 genotypes. C. difficile shows some resistance to ampiciline, clindamycin, metronidazole, but susceptive to vancomycin.

Aim To investigate the effects of emodin isolated from Guangxi P.multiflorum Thunb on the expression of KU70/KU80 in hypoxic nasopharyngeal cancer CNE-1 cells and reveal the relationship between radiosensitization of emodin monomer and DNA repair genes.Methods The expression of hypoxia inducible factor-1?(HIF-1?)and DNA double-strand break repair genes(KU70/KU80)between the experimental groups and the control group under hypoxic condition was detected by the real-time fluorescence quantitative RT-PCR.Results Expression of HIF-1? was significantly increased under hypoxia condition.HIF-1? had no change after treatment with emodin alone.The expression level of KU70/KU80 was induced by radiation.Compared with radiation alone group,radiation combined hypoxia group obviously enhanced the expression of KU70/KU80.KU70/KU80 mRNA expression significantly reduced after radiation combined with emodin under hypoxic condition.Conclusion In the hypoxic environment,emodin combined with radiotherapy can effectively inhibit the expression of HIF-1 ? and DNA double-strand break repair genes(KU70/KU80),which may be its mechanism of radiosensitization.
