AIM: To investigate the quality of life in adults with strabismus and evaluate the improvement in quality of life after treatment.
METHODS: In this prospective study, forty-five adults with a diagnosis of strabismus conform to the inclusion and exclusion standard were selected in our hospital from October 2013 to May 2014, as experimental group and 45 normal adults were enrolled as control group. A Chinese Adult Strabismus-20 questionnaire was used to evaluate the differences of quality of life between patients with strabismus and normal adults, and to evaluate the differences of quality of life in patients with strabismus preoperative and 6mo postoperative.
RESULTS:The scores of quality of life in adult patients with strabismus preoperative and 6mo postoperative were statistically significant lower than those of normal adults (P< 0. 01). In 6mo postoperative, the scores of quality of life statistically significant increased than preoperative ( P<0. 01).
CONCLUSION: Strabismus can decrease the quality of life in psychosocial and visual functional for adults and the surgical treatment can improve quality of life in patients with strabismus.

Objective To evaluate the feasibility and efficacy of catheter-directed thrombolysis (CDT) for the treatment of non-acute (history ＞ 14 days) deep venous thrombosis (DVT) of the lower extremity.Methods Clinical data of 63 patients of non-acute DVT of lower extremities treated by CDT and adjunctive angioplasty and stenting from July 2009 to August 2013 were analyzed retrospectively.Venous recanalization was graded by a thrombus score based on pre-and post-treatment venography.Follow-up was performed by Doppler ultrasound and clinical evaluation.Results A total of 63 limbs with DVT with a mean symptom duration of (22 ± 5) days were treated by a continuous combined with pulse-spray infusion of urokinase of (1.21 ± 0.69) million IU/d for (74 ± 21) hours.Significant recanalization was achieved in 77％ (48 of 63) of the treated limbs.After thrombolysis,percutaneous angioplasty was done for 15 residual lesions and stent placement was performed in 11 iliac veins and 1 femoral vein.Minor bleeding occurred in 6 (10％) patients,no patients suffered from major bleeding or symptomatic pulmonary embolism.During follow up (mean:15 ±6 months),the veins were patent in 45 (71％) limbs.15 (24％) limbs developed mild post-thrombotic syndrome (PTS),and none had severe PTS.Conclusions CDT combined with adjunctive angioplasty and stenting is safe and effective for removal of the clot burden and for restoration of the venous flow in patients with non-acute lower extremity DVT.

Objective To investigate the clinical manifesfations and diagnostic and therapeutic features of cholangiocarcinoma associated with hepatolithiasis.Methods The clinical data, the diagnotic and therapeutic featares of 54 cases of cholangiocacinoma associated with hepatolithiasis were retrospectively analyzed.Results The occurrence rate of hepatolithiasis concomitant with hepatocholangiocarcinoma was 11.8%.Due to a lack of specific clinical manifestations, the preoperative diagnosis of this condition was difficult. In this series, the (correct) diagnotic rate of hepatocholangiocarcinoma before operation was only 11.1%. The radical resection rate was 51.8%. Radical resection of the tumor had a better prognosis than that of non-resection of tumor.(Conclusions) Patients with long-term recurrent hepatolithiasis tended to have associated cholangiocarcinoma. Early diagnosis of the disease was difficult, and the treatment results and prognosis were poor. Therefore, (patients) with hepatolithiasis, espesially those with recurrent attacks, should undergo operation early. In cases diagnosed as hepatic cholangioearcinoma at operation, a radical resection should be performed, if possible, and a favorable outcome may be attained.

AimThe aim of this study was to establish a rodent model with similar characters of human metabolic syndrome(MS).Methods Three species mice and Wistar rats were fed with high energy chows(HEC)for 6 to 23 weeks.Animals were weighted every week.Fasting blood glucose(FBG)together with total cholesterol(TC)and low density lipoprotein-cholesterol(LDL-C)were investigated by oxidase test every two week.And fasting blood insulin(FINS)was determined by radioimmunoassay.Homeostasis model assessment of insulin resistance(HOMA-IR)was calculated as FBG×FINS/22.5.At the end of the experiment,oral glucose tolerance test(OGTT)was performed.Then animals were decapitated,and coel-fat and orchio-fat were collected and weighted to calculate the visceral fat coefficient(VFC).Results FBG,serum TC and LDL-C significantly increased(P<0.01)after 6 weeks feed of HEC in KM mice.The mice also formed abdominal obesity and insulin resistant together with impairment of glucose tolerance(P<0.05 or P<0.01).Though similar to the KM mice,C57BL/6 and BALB/c mice couldn't form abdominal obesity while the latter had increased body weight(P<0.05 or P<0.01).Wistar rats formed hyperlipidemia from 1 to 10 week and hyperglycemia from 10 to 23 week together with insulin resistance and impaired glucose tolerance(P<0.05 or P<0.01).Conclusion KM mice feed with HEC for 6 weeks could successfully establish metabolic syndrome mice model which might be suitable for drug-screening,the major characters includes the formation of abdominal obesity(increase of VFC),the increase of serum TC,LDL-C,FBG and HOMA-IR,and the decrease of OGTT.

Aim To investigate the effects of heme oxygenase-1(HO-1) on brain damage due to cerebral ischemia/reperfusion.Methods 120 male mice were divided into four groups randomly and the cerebral ischemia/reperfusion(I/R) model was established through drawing out and reperfusing 40% of the whole blood volume in combination with clamping the carotid arteries for 20 min after anesthesia with 40 g?L-1chloral hydrate(400 mg?kg-1 ip).The mice were intracerebraventricularly(icv) injected with 3(l of150 ?mol?L-1 hemin,150 ?mol?L-1 ZnPPIX,or artificial cerebrospinal fluid(ACSF),respectively 16 h before the model established.Sham operation group only received anesthesia and operation without I/R and icv injection.The hippocampal HO activity and cerebral cortex xanthine oxidase(XO) activity,the levels of malonaldehyde(MDA) and reactive oxygen species(ROS),hippocampal neuron apoptosis,and hippocampal HO-1 expression were determined by spectrophotometer,TUNEL method,and Western blot,respectively.Results The increased hippocampal HO-1 expression and HO activity,decreased XO activity,MDA and ROS levels,and diminished hippocampal apoptosis were observed in the hemin group,compared with ACSF group(P0.05),but inhibited the activity of HO with the elevation of XO activity,MDA and ROS levels,as well as cellular apoptosis(vs ACSF,P
