Twenty six patients with liver cancer who received liver transplantation were enrolled in the study. The patients were assessed by SF-36 scale and QOL-LC V2.0 scale before and 0 -6, 7 - 12, > 12 months after the liver transplantation. Scores in physical function domain and social function domain decreased significantly in the early stage post LT (0 -6 month post-LT). While in later stage ( >7 months post-LT), the scores showed no significant difference or even higher than that of pre-LT. In psychological function domain, no significant difference was found pre- and post-LT. The scores were improved significantly in later stage post-LT than pre-LT and early stage post-LT.

Objective To evaluate the effects on trabeculectomy combined with implantation of anterior lens capsule.Design Radomized,controlled experimental study.Participants 36 experimental albino rabbits.Methods 36 albino rabbits were divided into 3 groups randomly.The rabbit and human anterior lens capsules were implanted under the scleral flap in trabeculectomy in group A and group B respectively,while only trabeculectomy in control group.The average follow-up period was 12 months.Main Outcome Mea- sures Intraocular pressures(IOP),filtering bleb,complications.Results The postoperative IOP of the experimental groups decreased sig- nificantly as compared with preoperative IOP at 12 week postoperatively.Retention of reflective filtering bleb in experimental groups was longer than that in contral group(5.12?0.43week,5.05?0.59week,2.74?0.32week,P＜0.05).The passage of humor outflow kept open in ex- perimental groups and became closed in control group at 12 week postoperatively.Anterior lens capsule wasn't attacked by T or B lym- phocyte seen with electron microscope.Conclusions Implantation of anterior lens capsule may help to postpone filtering bleb scarring in the trabeculectomy.This study provides experimental basis for the clinical practice.

Objective To explore the mucosal healing quality of hydrotalcite combined with esomeprazole in gastric ulcer.Methods Forty-two patients visiting from June 2014 to December 2015 and diagnosed with gastric ulcer were selected and divided into combination therapy group and single therapy group with 21 patients in each group.The patients of combination therapy group received esomeprazole combined with hydrotalcite,and the patients of single therapy group received esomeprazole alone.The total therapeutic course was eight weeks.At the same period,21 health check-up participants were enrolled as normal control group.The healing of gastric ulcer was observed under white light endoscopy.The morphological changes of gastric pits and microvessel of mucosal at peripheral mucosa around ulcer and normal gastric mucosal were observed under narrow band imaging magnifying endoscopy.The gastric mucosa tissues of the two groups before and after treatment,and normal gastric mucosa of healthy control group were taken.The amount of deposition and composition of collagen fibers,the expression level of factor Ⅷ,the level of transforming growth factor (TGF)-beta1 and the content of hydroxyproline were analyzed by Masson,immunofluorescent and immunohistochemistry staining as well as enzyme linked immunosorbent assay.Chi square test,one-way analysis of variance (ANOVA),least significant difference (LSD) method,Dunnett's T3 and Kruskal-Wallis test and other method were used for comparison.Results After treatment,18 patients of combination therapy group (21 patients) had regular microvessel nets (85.7％),which was significantly more than those of single therapy group (12 cases,57.1％) and healthy control group (10 cases,47.6 ％),and the differences were statistically significant (x2 =4.200,P=0.040).In the comparison of maturity of regenerative mucosa between combination therapy group and single therapy group after treatment,the ration between collagen type Ⅰ and Ⅱ,deposition of collagen fibers,the number of factor Ⅷ positive cells,the level of TGF-beta1 and the content of hydroxyproline were 36.05 and 23.14;269 375.63.± 171 608.63 and 137 693.14±98 330.93;34.91±8.40 and 28.24±6.93;104 498.71±40 487.96 and 70 757.11±19 323.95;(1 897.80±879.35) and (1 230.57±536.05) μg/L,respectively;while in healthy control group,the above parameters were 36.81,245 696.90 ± 224 687.00,23.10 ± 8.40,94 048.04 ±41 306.55 and 1 681.20 ± 423.61 μg/L,and the differences were statitically significant among these three groups (H=7.375,F=3.465,11.680,5.190,5.160;all P＜0.05).Those parameters of combination therapy group were significantly higher than those of single therapy group (H=2.416,LSD method;all P＜0.05).Conclusion Hydrotalcite combined with esomeprazole in the treatment of gastric ulcer could significantly improve microvessel morphology,maturity degree of regenerative mucosal structure and function,and the mucosal healing quality was also superior to single esomeprazole group.

Objective To investigate the value of diffusion weighted magnetie resonance imaging and apparent diffusion coefficient (ADC) value in the diagnosis of pancreatic cancer.MethodsThe clinical data of 36 patients with pancreatie cancer who were admitted to the Wuxi No.2 People's Hospital from March 2009 to June 2011 were retrospectively analyzed,and the clinical data of 30 healthy volunteers were collected.All candidates received diffusion weighted magnetie resonance imaging examination.The signal intensity ratios ( SIRs ) of the cancer and the pericancerous tissues in the T1 weighted-images (T1WI),T2 weighted-images (T2WI)and diffusion weighted-images (DWI) were compared by using one-way analysis of variance.The ADC values of the cancer and the paricancerous tissues were compared using the paired t test.The differences of the ADC values of the cancer and pericancerous tissues compared with those of healthy individuals were analyzed using an independent sample t test.ResultsThe accuracy rate of preoperative magnetic resonance imaging examination was 92％.The relative SIRs were 0.203 ± 0.190 in the T2 WI,0.399 ± 0.201 in the T1 WI and 0.579 ± 0.291 in the DWI,respectively,with no significant differences across the 3 kinds of images (F=5.92,6.15,6.83,P ＜ 0.05 ),while SIRs of the T1 WI and DWI were significantly higher than that of the T2 WI ( P ＜ 0.05 ).There was no significant difference in SIRs when comparing T1 WI and DWI ( P ＞ 0.05 ).The mean ADC values of the cancer and pericancerous tissues of the pancreatic cancer patients and the pancreatic tissues of healthy individuals were (1.40±0.24) ×10 3 mm2/s,(1.71 ±0.10) ×10-3 mm2/s and (1.73±0.30) ×10-3 mm2/s,respectively,with significant differences across the 3 modes of images (t =10.54,12.08,P ＜ 0.05).ConclusionDWI can show high quality images of the lesions,and ADC value is helpful in the diagnosis of pancreatic cancer.

Objective To analyze the stability of chromosome variant ratio of three available transformed corneal cell lines. Methods Chromosome specimens of transformed cells including human corneal epithelial cells(HCE),bovine corneal endothelial cells(BCE) and rabbit corneal epithelial cells(RCE) were prepared by a direct method using regular Giemsa staining. Chromosomes of cells in metaphase were counted under the microscope. Then, the variant ratio of chromosomes and their nuclear types were analyzed. Results The chromosome numbers were 56 to 65, 27 to 34 and 74 to 88 for HCE, BCE and RCE, respectively. Chromosome numbers in the three commonly used and transformed corneal cell lines were changed in comparison to their parent tissues. Conclusion Genotyping study may provide important information for using HCE、BCE、RCE in functional studies.

Objective:To explore the urgent management strategy for quadriplegia following China Wenchuan earthquake under filed condition.Methods:The 57-year-old male patient was sent to the earthquake relief team of Changzheng Hospital,Second Military Medical University.He was hit by heavy object during the Sichuan earthquake 6 days ago.Physical examination revealed cervical spinal cord injury accompanied by incomplete paralysis.The patient underwent cervical 3-7 laminectomy under general anesthesia.Results: After surgery,the muscle strength of lower limbs recovered to grade four from grade one;the muscle strength of upper limbs recovered to grade five from grade three.Sensory loss was found below the nipple level and totally recovered after operation.Conclusion:Early surgery for quadriplegia following earthquake trauma can timely relieve compression to the spinal cord and therefore improve prognosis of patients.Under field condition where facilities are not readily available,decompression of spinal cord can be achieved by lamineetomy via posterior approach.The key to successful operation is correct diagnosis and skillful manipulation.

Objective To investigate the early clinical outcome of peripheral cutting balloon(PCB) in the management of peripheral vessel stenosis.Methods Thirteen patients with peripheral limb vessel stenosis, in which 4 stenoses in hemodialysis access and 9 at lower limb arteries,underwent angioplasty by PCB.For multiple stenosis in the same vessel,the distal one should be expanded firstly.The balloon pressure was controlled in the range of 8 atm to 10 atm(1 atm=10.108 kPa).All the patient were given continuous anticoagulant therapy after the procedure.Results All the procedure were carried out successfully on the 13 patients,and no serious complications occured.The symptoms did not recur in all patients after the procedure.The 5 months' follow-up angiography proved that no restenosis occurred in one patient with previous stenosis at the hemodialysis access.Conclusion The angioplasty with PCB was a safe and reliable procedure in management of the peripheral limb vessel stenosis.The early outcome is satisfying.
