Background The parameter of corneal diameter in myopic eyes is widely used in clinic,but there are different points of view about the correlation of corneal horizontal diameter with other parameters of the myopic eye.Objective This study was to investigate the relevance of the other parameters to the corneal horizontal diameter(CHD)of myopia.Methods A total of 310 cases(310 eyes)of myopic patients aged 6-50 years old who visited Affiliated First Hospital of Zhengzhou University were collected for the study.Measuring items included gender,age,myopia diopter and corneal topography.The relationships between the CHD of the right eyes and seven factors including age,gender,degree of myopia,corneal curvature (CC),corneal astigmatism (CS),corneal central thickness(CCT),and anterior chamber depth (ACD)were analyzed by empower stats software.Results The distribution range of CHD was from 10.8 mm to 13.5 mm,with the average value (11.7±3.8)mm.There were significant differences in the CC and ACD between male and female patients by t test(t =-1.574,P＜0.001 ;t=-1.145,P =0.034).Through the smoothing curve fitting,the threshold effect and single factor and multiple regression analysis,the CHD was negative linear relationship with CC (β =-0.085,P =0.011).The ACD positive linear relationship with CHD was found (β=0.722,P＜0.001).And the CHD was not correlated with the degree of myopia,CS,CCT and gender(β =0.000,0.084,-0.001,0.105;all at P＞0.05).There was different inflection point in the curve relationship between male patients and female patients.Conclusions The CHD is linear negatively correlated with CC and line positively associated with ACD in 6-50 years old myopic patients.There is no relationship between CHD and gender,spherical equivalent degree,CS,CCT.There is curvilinear relationship with inflection point between CHD and age.

OBJECTIVETo observe clinical efficacy of renovation stem revision femoral head arthroplasty for the treatment of unstable intertrochanteric fracture in the elderly.

METHODSTotally 32 elderly patients with unstable intertrochanteric fracture were treated with renovation stem revision femoral head arthroplasty from September 2007 to January 2011. There were 11 males and 21 females with an average age of 83.8 (ranged, 80 to 98) years old,the time from injury to hospital ranged from 4 h to 14 days. According to Evans-Jensen classification, 6 cases were type II a, 20 cases were type II b, and 6 cases were type III. Postoperative mortality, complication rates and Harris hip function score were compared and analyzed to evaluate curative effect.

RESULTSAll patients were followed up and no dislocation occurred. Six patients were died during 15 months and 4.5 years; 24 cases recoved to independent wakling at 6 months after operation, and 8 cases walked with stick and walker. The average Harris hip joint function score were (91.56 +/- 2.96), 28 cases got excellent results and 4 cases good. Nine cases occurred complications and healed after treatment.

CONCLUSIONRenovation stem revision femoral head arthroplasty is a active and reliable method in treating unstable intertrochanteric fracture in the elderly.

TTI gene coding for Tsetse thrombin inhibitor was modified with E.coli bias codon and expressed in Escherichia coli with high efficiency.Recombinant protein was purified to more than 98% purity.Assay for enzyme activity determination was set up.The result showed that the fusion protein exhibited inhibiting activity for thrombin.Inhibitory rate of purified TTI was 73% when concentration of thrombin and substrate was 10U/ml and 250?mol/L respectively.Inhibition pattern was determined as competitive with Ki at 35?mol/L.

Objective In this research,the relationship between blood estrogen level and salivary glands of female rat was studied.Methods Thirty-two female Wister rats were randomly divided into four groups:control group,sham operation group,ovariectomized and injected estradiol benzoate group and ovariectomized group.Menopausal rat model was established by ovariectomy.By testing E2,histological examination and examing Cu,Zn-SOD expression through immunochemical staining,we studied the effects of estrogen decreasing on female rat salivary.Results Compared with control group,sham operation group,ovariectomized and injected estradiol benzoate group,a significant decrease in scrum estrogen level was observed in ovariectomized group(P

Objective To examine the expression and analyze the significance of autophagy-related gene microtubule-associated protein 1 light chain 3 (MAP1-LC3,LC3),p62 and lysosorne-associated membrane protein 2 (LAMP-2) in pancreatic tissues of mice with acute pancreatitis (AP).Methods Twenty mice were randomized into AP group and control group,and the number of mice was equal between two groups.AP group was intra-peritoneally injected by 20％ L-arginine solution (two injections of 4 g/kg body weight,every 1 h) in the dosage of 4 g/l kg twice every 1 hour to establish AP model,while control group was administered with equal volume of normal saline by intra-peritoneal injection.All the mice were euthanized at 24 hour after the last injection.Pancreatic histopathological changes were measured.In addition,the protein expressions of LC3,p62 and LAMP-2 were detected by Western blot.Results No obvious pathological changes were observed in control group.Pancreatic acinar edema,structure destruction,missing,the obvious widening of interlobular septum,small interlobular septum and acinar septum,and the necrosis of acinar cells at different degrees were observed in AP group.The pathological score for tissue edema,hemorrhage,necrosis and inflammation in AP group was 3.13 ± 0.50,2.83 ± 0.32,3.25 ± 0.46 and 3.16 ± 0.47,respectively,which was all 0 in control group.The differences were statistically significant between AP group and control group (P ＜ 0.01).In AP group,the ratio of LC3-Ⅱ/LC3-Ⅰ,p62 and LAMP-2 protein in pancreatic tissue were 1.16 ± 0.08,0.94 ± 0.04 and 0.35 ± 0.04,respectively,which were 0.24 ± 0.02,0.34 ± 0.03 and 0.95 ± 0.03 in control group.The ratio of LC3-Ⅱ/LC3-Ⅰ and p62 protein in pancreatic tissue in AP group were much higher than those in control group,while LAMP-2 in AP group was lower than that in control group,and there was statistically significant difference between two groups (all P ＜0.01).Conclusions Intraperitoneal injection of L-arginine could induce acute pancreatitis,and autophagy is impaired,which was associated with decreased LAMP-2 protein expression.

Objective To compare the application of ambulatory urodynamic(AUM)and conventional urodynamic(CUD)in detecting stress urinary incontinence(SUI)and detrusor overactivity(DO)in females.Methods Incontinence questionnaire short form(ICI-Q-SF),CUD and AUM were administrated on 30 female patients with the mean age of 49.4(32-63)years.The duration of symptom was 4.7 (1-9)years.The patients were divided into 3 groups of mild(n =9),moderate(n =15)and severe (n =6)according to ICI-Q-SF.Three micturition cycles were recorded during AUM.Results SUI and DO detected by AUM were 90％ and 37％,significantly more than those by CUD of 70％ and 10％(P ＜0.05).Twenty-one moderate and severe SUI patients diagnosed by ICI-Q-SF,detected by AUM and CUD simultaneously showed that abdominal leak point pressure(ALPP)and voided volume were lower,and detrusor pressure was higher recorded by AUM than those by CUD significantly(P ＜ 0.05).Conclusions SUI and DO are easier detected by AUM than by CUD.AUM is a useful additional tool in clinical practice for those patients CUD failed to explain their symptoms.

OBJECTIVETo study the healing effect of pneumoconiosis with tetrandrine and massive whole-lung lavage.

METHODSChoose 34 confirmed pneumoconiosis patients as drug treatment group and complex treatment group, and 17 tested workers as control group. Collected the content of TGF-beta1 and P III P which in these three investigated groups.

RESULTSDrug treatment group and complex treatment group of patients improved the clinical symptoms and lung function Compared with Pretreatment, the FVC, FEV1.0, FEV1.0/FVC, MVV was obviously higher than those before treatment (P < 0.05). Complex treatment group than in the drug treatment group increased more significantly (P < 0.05). The level of TGF-beta1 and P III P was reduced after complex treatment (P < 0.05). Moreover,the level of TGF-beta1 and P III P in these patients are lower than in those patients treated with tetrandrine combined with whole lung lavage (P < 0.05).

CONCLUSIONTetrandrine combined with whole-lung lavage could significantly retard the development of pneumoconiosis by lessening the TGF-beta1 and P III P in serum.
