Objective To study the effect of estrogen on cardiac injury and cardiomyocyte apoptosis of rat induced by isoprotere-nol by modeling cardiac inj ury induced by bilateral ovariectomized (OVX)and isoproterenol (ISO).Methods Fifty female SD rats with bilateral ovariectomy and sham operation (Sham)were randomly divided into 5 groups:sham operation group (Sham group), bilateral ovariectomy group (OVX group),cardiac injury group (OVX+ISO+Vehi group),low dose estrogen treatment group (OVX+ISO+E2 a group,4μg·kg-1 ·d-1 ),high dose estrogen treatment group (OVX+ISO+E2 b group,40μg·kg-1 ·d-1 ). these status were separately measured:rats′general features,hemodynamics parameters monitored of carotid artery,morphological observation and cardiomyocyte contraction change of single-cardiomyocyte separate cultured,cardiomyocyte apoptosis protein ex-pression were detected by immunoblotting.Results ISO significantly reduced myocardial pump function,increased hypertrophy and apoptosis of cardiomyocytes,reduced contractility of single cardiomyocytes (P<0.05).High-dose estrogen (40μg·kg-1 ·d-1 ) replacement therapy significantly improved ISO induced cardio inj ury and cardio functions decreasing,also inhibited Bax expression and caspas-3 activation and decreased myocardial hypertrophy and cardiomyocytes apoptosis through increasing Bcl-2 expression (P<0.05),significantly.while low dose estrogen (4μg·kg-1 ·d-1 )treatment showed marginally protection effects on ISO in-duced cardio inj ury with no statisticly significance.Conclusion Appropriate dose estrogen replacement therapy can decrease cardio-myocyte apoptosis,improve cardiomyocytes contractility,so as to protect ISO-induced cardiomyocyte apoptosis.

AIM:To evaluate the clinical effects of femto-LASIK using new Ziemer LDV Z6 femtosecond laser machine (Z6).
METHODS: Two - hundred cases ( 400 eyes ) was randomly separated into two groups: Group A included 200 eyes which corneal flaps were made by Z6, and Group B included rest of 200 eyes which corneal flaps were examined by a traditional Ziemer LDV CrystalLine femtosecond laser machine (CrystalLine). Visual acuity, slit lamp, refraction, Sim-K average, intraocular pressure (IOP), non-invasive tear break-up time (NIAvg-BUT), operation difficulty and complications were compared between two groups preoperatively and postoperatively.RESULTS:There was no significant differences between two groups in visual acuity, refraction, Sim-K average, IOP and NIAvg - BUT either preoperatively or 6mo postoperatively (P>0. 05). Although there were significant differences in operation difficulty and complications were found between two groups ( P< 0. 05 ), there was no serious complication in any group. Furthermore, a clear demarcation line could be observed in the cornea of Group A postoperatively.
CONCLUSION:More careful and strict requirements are needed when using the new Z6 femtosecond laser for corneal flaps.

Objective To investigate the signal transduction pathway mechanisms of rats with liver fibrosis regulated by leptin and interfering effects of mistletoe alkali .Methods The hepatic fibrosis in rats model was established by injecting carbon tetrachloride .Forty-five SD rats were randomly divided into normal group ,model group and therapeutic group.All rats except rats in normal group were intraperitoneally injected with 40%carbon tetrachloride in peanut oil with a dose of 2.0 mL/100g according to the body weight twice a week for 8 weeks.Then, the therapeutic group was given mistletoe alkali (8g/(kg· d)) for 8 weeks via gastrogavage.Rats in normal and model group were served with distilled water at the same time.At the end of the 16th week, blood and tissue specimens were taken from all the rats .The influence of mistletoe alkali on liver morphology in liver fibrosis rat model was reviewed by HE and Masson staining .The effects of mistletoe alkali on the expression of Leptin and its receptor ( OB-Rb ) in HSC in fibrosis rat model were determined by immunohistochemistry (IH).The expression of JAK2, STAT3 and the activity of phospho -JAK2, phospho-STAT3 were detected by Western blotting analysis .Results The degree of fibrosis of the model group was more severe than the normal group and the treatment group , which suggested that mistletoe alkali can reverse liver fibrosis in rats . Immunohistochemical staining showed that mistletoe alkali reduced the hepatic expression of leptin and OB -Rb in rats with liver fibrosis in comparison with their expression in the model group .Compared with the normal group , the expression of JAK2 and STAT3 increased in the model group .However, the expression of JAK2 and STAT3 decreased in the medication groups compared with the model group .Conclusion Mistletoe alkali can effectively ameliorate liver fibrosis in rats possibly through inhibiting hepatic leptin and its receptor expressions , which through inhibiting hepatic leptin and its receptor expressions , thus inhibit the JAK2/STAT3 signaling pathway .

Objective To study the long-term results of using an autologous vascularized pedicled flap of gastric tissues in the repair of traumatic bile duct strictures.Methods From 2002 to 2016,38 patients with traumatic bile duct strictures underwent repair using an autologous vascularized pedicled flap of stomach tissues.The postoperative morbidity,mortality,long-term clinical results,liver function and the rate of biliary stricture recurrence were studied.Results The overall complication rate was 18.4％ (7/38).A delay in healing of the incision wound occurred in 4 patients,biliary fistula in 2,and ascites in 1.Two patients died of malignant tumor.The median follow-up was 92 (61 ～ 107) months and the follow-up rate was 100％.Excellent results were obtained in 97.2％ (35/36) of patients.Abnormal liver function was detected in 1 patient which improved with treatment using choleretic drugs.The remaining 35 patients had normal liver functions with absence of abdominal pain.Conclusions To repair traumatic bile duct strictures using an autologous vascularized pedicled flap of stomach tissues was safe and reliable,and good long-term outcomes are available.

To the cataract patient after corneal refractive surgery, if the intraocular lens power was determined by conventional formulas, different refractive errors may be produced after intraocular lens implantation.This inaccuracy of the lens power mainly came from 2 aspects-errors of corneal refractive power measurement and errors of formulas.Besides, imprecise of ocular axial length measurement and invalid lens position calculation also contributed to the inaccuracy of lens power.Therefore, in order to reduce refractive errors of cataractous surgery in patient underwent refractive surgery, appropriate method should be used to estimate the refractive power of corneal, and proper formula should be selected to calculate intraocular lens power.

Objective To investigate the effects of pretreatment with remifentanil on hemorrhagic shock (HS)-induced acute liver injury in rabbits.Methods Thirty-two New Zealand white rabbits,weighing 2.0-2.5 kg,were randomly divided into 4 groups (n=8 each): sham operation group (group S) ; group HS,low-dose remifentanil group (group RL) ; high-dose remifentanil group (group RH).Remifentanil was infused at 0.66 and 1.32 μg· kg-1 · min-1 for 145 min in groups RL and RH respectively,while the equal volume of normal saline was infused in group C.HS was induced by withdrawing blood from the left femoral artery at 15 min after continuous infusion of normal saline or remifentanil and mean arterial pressure (MAP) was reduced to 40 mm Hg.MAP was reduced to 35-45 mm Hg and maintained at this level for 120 min in groups HS,RL and RH.Blood samples were taken for determination of serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activities before administration (T0),immediately before blood letting (T1),and at 10,30,60 and 90 min after blood letting (T3-6).The animals were then sacrificed and the livers were immediately removed for microscopic examination.Results Compared with group S,the serum ALT activity at T5 and T6 and serum AST activity at T4-T6 were significantly increased in the other three groups (P ＜ 0.05).Compared with group HS,the serum ALT activity at T5 and T6,and serum AST activity at T4-T6 were significantly decreased in group RH,and no significant change was found in group RL (P ＞ 0.05).Compared with group RL,the serum ALT activity at T5 and T6,and serum AST activity at T4-T6 were significantly decreased in group RH (P ＜ 0.05).The serum ALT activity at T5 and T6 and serum AST activity at T4-T6 were significantly increased in groups HS,R and RH than those at T0 (P ＜ 0.05 or 0.01).The patho1ogical injury was attenuated in group RH compared with groups HS and RL.Conclusion Remifentanil pretreatment can attenuate HS-induced acute liver injury in rabbits,and the effect is related to the dose.

Objective To evaluate the efficacy of ultrasound ablation and balloon angioplasty in treating peripheral arterial occlusion in diabetes mellims. Methods One hundred and fifty-eight patients with peripheral arterial occlusion were treated with the ultrasound ablation. Through percutaneous approach or surgical approach, the ultrasound ablation catheter was inserted into occluded arterial segments. Results The ultrasound ablation was successful in 149 of 158 patients (94%). After treatment, the average skin temperature rised for 3℃ and the distance of intermittent claudicafion was increased for 1 000 m. The gangrene was mitigated in 38 of 45 patients. The pain during rest was ameliorated in 31 of 35 patients. Long-term efficacy was 75%. Conclusion Ultrasound ablation is effective and is a new approach for treating peripheral arterial occlusion in diabetes mellitus.

Aim To investigate the relationship between GABAA receptor or NMDA receptor and the amnestic effect induced by etomidate.Methods Amnestic model was established by intraperitoneal injection of etomidate(3 mg?kg-1) in mice before intracerebroventricular injection of different doses of bicuculline or NMDA,then the error times,step down latency and step through latency were observed and recorded in the step down test and step through test.Results Bicuculline(2,4 ?g) instead of NMDA by intracerebroventricular injection could decrease the error times and increase the step down latency and step through latency of amnestic mice in the step down test and step through test.Conclusion GABAA receptor rather than NMDA receptor may be an important target for the amnestic effect induced by etomidate.
