Objective To evaluate the preoperative localization value of MRI and MRCP for congenital biliary dilatation.Methods 30 cases of congenital biliary dilatition diagnosed by either surgery or pathology were studied.MRI and MRCP findings of all these cases were analyzed.Results MRI and MRCP preoperative examination manifested the place of choledochal cyst and the relation between choledochal cyst and the biliary ductal system around in all 30 patients.Through surgery findings as follow,using Todani's classification,the accuracy of MRI and MRCP in evaluating the site and classification of congenital biliary dilatation was 100%,the accurate visualization rate of pancreatic duct was 73.3% and the junction of pancreaticobiliary duct was 33.3%.Conclusion MRI and MRCP manifestations are very reliable in preoperative localization of congenital biliary dilatation.

Objective To evaluate the changes of reticulated platelets (RP)in diagnosis and treatment of idiopathic thrombocytopenic purpura (ITP). Methods RPs were measured by flow cytometry and the percentage and absolute counts of RPs were calcula- ted in ITP group,non-ITP group and control group.Results Compared with control group,ITP group had a significantly high percentage and low absolute counts of RPs (P

The determination and characterization of solid drug form polymorphisms plays an important role in drug quality control, selection of the production process and clinical efficacy evaluation. Vibrational spectroscopy is a powerful method for the characterization of drug polymorphisms. In this paper we review recent research and application advances in the polymorphic characterization of active pharmaceutical ingredients (APIs) and drug cocrystals/salts by using Fourier transform infrared (FTIR) and Raman spectroscopy to elucidate the characteristics of APIs and drug complexes. This may provide theoretical support for structural analysis during the development process for drugs.

Objective: To establish a method for the determination of paracetamol, caffeine and chlorphenamine maleate in Compound Ganmaoling Tablets. Methods: The RP-HPLC was conducted on a Phenomenex C 18 column(5?m,250mm?4.0mm) with methanol: water: acetic acid(35∶65∶1.5) as a mobile phase, detect wavelength at 270nm. Results: Paracetamol, caffeine and chlorphenamine maleate respectively showed good linear relationship in the following concentrations of ranges:50.4～117.6?g?mL -1,3.6～8.4?g?mL -1,0.84～1.96?g?mL -1; The average recoveries were obtained as 99.9%,99.8%,100.0%(n=6); respectively. Conclusion: The method was simple, sensitive, accurate and suitable for the determination of three constituents in Compound Gamaoling Tablets.

The most effective treatment for acute ischemic stroke is intravenous thrombolysis and endovascular treatment. The proportion of patients with acute ischemic stroke receiving intravenous thrombolysis and endovascular treatment in China is low, and pre-hospital delay is an important reason. This article reviews the influencing factors and intervention measures of pre-hospital delay.

BACKGROUND: The commonly used culture methods for primary intervertebral disc cells are type Ⅱcol agenase alone digestion method, and type Ⅱ col agenase combined trypin digestion method. However, the acquired cells are few. OBJECTIVE: To acquire nucleus pulposus cells from human degenerative intervertebral disc using a systemic and simplified method. METHODS: Nucleus pulposus cells were isolated and cultured. The morphology of nucleus pulposus cells was observed under inverted phase contrast microscope every day. Primary and subcultured cellsuspension was applied for the determination of cel viability using trypan blue staining. The cel growth was detected with MTT assay. The cel morphology was observed under laser confocal microscopy. RESULTS AND CONCLUSION: Nucleus pulposus cells were successful y isolated from from human degenerative intervertebral disc using the improved method, and cells were subcultured to passage 3. Primary cells were fusiform shaped, while cells at passage 1 and 2 were triangle or polygonal, which were similar to fibroblasts. When cells almost reached the confluence, the cells showed slabstone-like appearance. Trypan blue staining showed that, the primary cel viability was 99%, and passage 3 cells had 93%-95% viability. The proliferation of nucleus pulposus cells gradual y decreased as the generation increased. Compared with passage 1 cells, passage 2 and 3 cells at logarithmic phase trended to be smoother. The cel morphology observed under laser confocal microscopy was similar to the results under phase contrast microscope. The improved simple method can successful y acquire a variety of cells from human degenerative intervertebral disc, and these cells show fine biological properties.

Objective To determine the perioperative risks of partial hepatectomy by determining the preoperative liver functional reserve in patients with hepatocellular carcinoma (HCC),and to compare the model for end-stage liver disease (MELD) score with the Child-Pugh classification in predicting prognosis.Methods We reviewed the clinical data of 202 patients with HCC who underwent partial hepatectomy.The MELD score and the Child-Pugh classification were determined preoperatively.Results The incidence of postoperative liver dysfunction happened in 44.0％ of Child A patients,50％ in Child B patients,41.6％in patients with a MELD score below 14,and 91.7％ in patients with a MELD score of ＞ 14.The difference between the rates of postoperative liver dysfunction in patients with a preoperative MELD score above 14 and below 14 was significant (P ＜ 0.05),while that between patients with Child-Pugh A and B was insignificant (P ＞ 0.05).The incidences of postoperative liver dysfunction in patient with a MELD ＜ 8,8 ≤ MELD ≤ 14,MELD ＞ 14 were 38.2％,57.6％ and 91.7％,respectively,indicating that there was a positive co-relationship between the MELD score and the incidences of liver dysfunction.The Spearman rank correlation test showed the MELD score was significant correlated with the Child-Pugh score (r =0.404 ; P ＜ 0.05).The areas under the ROC curves of the MELD score and the Child-Pugh score were 0.703 and 0.587 (P ＜ 0.05).Conclusions The MELD score predicted postoperative liver dysfunction more accurately than the Child-Pugh classification.HCC patients undergoing partial hepatectomy with a preoperative MELD score ＞ 14 had a high perioperative risk.To ensure the safety of partial hepatectomy,HCC patients with a preoperative MELD score ＞ 14 requires active preoperative preparation,bringing the score near to or less than 14.

AIM: To analyze the associated factors of poor vision after phacoemulsification operation.
METHODS:Clinical data of cases with poor vision after cataract phacoemulsification combined with IOL implantation from 341 patients(418 eyes) during Jan. 2015 to Jan. 2016 in our hospital were collected and logistic correlation analyzed.
RESULTS: The incidences of postoperative low vision were 10. 3% for one month after operation. Forty-three eyes were reported low vision, and 41 of 43 the patients with postoperative low vision had fundus oculi disease before operation, which included 20 eyes ( 48. 8%) with age-related macular degeneration, 16 eyes(39. 0%) with diabetic retinopathy, 3 eyes ( 7. 3%) with glaucomatous optic neuropathy, 1 eye(2. 4%) with pathologic myopia of retinopathy and 1 eye ( 2. 4%) with branch retinal vein occlusion.
CONCLUSION: The associated factors of poor vision after phacoemulsification operation are preoperative eye diseases and the nuclear hardness, and preoperative eye diseases may be the main causes of postoperative low vision. Comprehensive examination should be attached importance to, and be careful in the operation to decrease the harm for visual performance.

OBJECTIVETo investigate clinical outcomes of Kirschner wire as blocking screws combined with interlocking intramedullary nail internal fixation in treating tibial metaphyseal fractures (AO 43A).

METHODSFrom March 2011 to June 2012, 9 patients with tibial metaphyseal fractures were treated with blocking screws Kirschner wire combined with interlocking intramedullary nail, including 7 males and 2 females aged from 23 to 54 years old with an average of 37.4. Postoperative complications, X-ray were observed, AOFAS scoring were used to evaluate function after operation at 12 weeks.

RESULTSAll patients were followed up from 6 to 40 weeks (mean 20.1), and healed at stage I. No serious swelling, infection and skin necrosis occurred. No fracture instability and displacement appeaered at 4 and 8 week after operation. AOFAS score was (95.2±4.6) at 12 weeks after operation and 7 patients gained excellent result and 2 patients good.

CONCLUSIONKirschner wire as blocking screws with interlocking intramedullary nail for treatment of tibial metaphyseal fractures can fix well and perform simply.
