Objective To evaluate the diagnostic values of location and qualitation of tendinitis of rotator cuff. Methods One hundred and sixty-two shoulders with shoulders pain or functional incapacity were performed ultrasonography and the sonograms were classified. Results Ultrasonic findings of these tendinitis were tendinitis of caput longum musculi bicipitis brachii in 39 cases, tendinitis of caput longum musculi bicipitis brachii in 33 cases, supraspinatus tendinitis in 51 cases, calcific supraspinatus tendinitis in 19 cases and bursitis of shoulder in 20 cases,especially. Conclusions Ultrasonography is a useful tool for diagnosis of tendinitis of rotator cuff in location and qualitation.

Objective To explore the effect of different cold ischemia (CI)times on the patterns of intra-graft T cell activation gene-3 (TCA-3) expression early after isogeneic half liver transplantation (PLT)in mice. Methods The models of C57BL/6 full-size(FS) and PLT were established.The CI time was 1,4 and 8 h.Specimen were collected at 4 and 24 h post-reperfusion.Ribonuclease protection assays (RPA)was used to evaluate serial mRNA expression of the TCA-3 chemokine in all mice.Histopathology was used to examine cold ischemia injury in the liver grafts. Results A total of 45 control and 30 PLTs were performed.The survival rate at 7 day after control and PLT was 100％.Quantitative analysis demonstrated the levels of TCA-3 mRNA expression were low at 4 h after reperfusion in control group with 1,4,8 h CI.The levels of TCA-3 significandy increased at 4 h after reperfusion in PLT group with CI of 1,4,8 h and the difference between the two groups was statistically significant ( F =7.41,P ＜ 0.05 ). TCA-3 mRNA expression significantly decreased at 24 h after reperfusion in two groups. But the difference was not statistically significant ( P ＞ 0.05 ). Histopathology showed severer cold ischemia injury in PLT grafts compared with control grafts. Conclusions The expression of TCA-3 significandy increased early after PLT and played an important role in cold ischemia injury.TCA-3 could be used as the early therapeutic target for reducing ischemia injury in PLT grafts.

In this work, datasets of water and carbon fluxes measured with eddy covariance technique above a summer maize field in the North China Plain were simulated with artificial neural networks (ANNs) to explore the fluxes responses to local environmental variables. The results showed that photosynthetically active radiation (PAR), vapor pressure deficit (VPD), air temperature (T) and leaf area index (LAI) were primary factors regulating both water vapor and carbon dioxide fluxes. Three-layer back-propagation neural networks (BP) could be applied to model fluxes exchange between cropland surface and atmosphere without using detailed physiological information or specific parameters of the plant.

Objective To evaluate the efficacy of transarterial chemoembolization (TACE) and percutaneous cryosurgery sequential therapy for unresectable hepatocellular carcinoma (HCC).Methods Four hundred and twenty patients with unresectable HCC were divided into sequential TACE-cryosurgery sequential (sequential) group (n=290) and cryosurgery alone (cryoalone) group (n = 130). TACE was performed with the routine operation; the percutaneous cryosurgery was conducted 2 to 4 weeks after TACE. The patients were followed up at the first month and once every 2 to 3 month later. Liver ultrasound or both computer tomography and alpha fetal protein were examined during follow-up. Results During a mean follow-up of (42±17) months (range from 24 to 70 months), the local recurrence rate of ablated lesion was 17% for all the patients, 11% and 24% for patients in sequential group and cryoalone groups respectively (P=0. 001). The overall 1-, 2-, 3-, 4-and 5-year survival rate was 72%, 57%, 47%, 39% and 31%, respectively. The 1- and 2-year survival rates (71% and 61 % ) in sequential group were similar to those (73 % and 54 % ) in cryo-alone group (P=0.69 and 0. 147), while the 4- and 5-year survival rates were higher in sequential group (49 % and 39 % ) than those (29 % and 23 % ) in cryo-alone group (P= 0.001). Eighteen patients with large HCC (＞5 cm in diameter) in sequential group survived for more than 5 years while no one in cryo-alone group. Complication rate was 24% in all patients, 21% and 26% for the sequential and cryo-alone groups respectively (P=0. 06). The incidence of hepatic bleeding was higher in cryo-alone group than in sequential group (P=0. 02). Liver crack occurred in two patients of the cryoalone group. Conclusions Pre-cryosurgical TACE increased the cryoablation efficacy and decrease its complications, especially hepatic bleeding. TACE and cryosurgery sequential therapy may be a better treatment for unresectable HCC, especially for large HCC.

OBJECTIVETo study the proper way of using combined postoperative chemo-radiotherapy and prognostic factors of soft tissue sarcoma.

METHODSThe clinical data of 184 patients were retrospectively reviewed. These patients were devided into surgery group (S, 94 patients), surgery plus postoperative radiotherapy group (S + R, 62 patients) and surgery plus chemotherapy group (S + C, 28 patients).

RESULTSThe 5-year survival rates of S, S + R and S + C groups were 39.4%, 48.4% and 28.6%, respectively. Combined multitherapy was the key to improve survival rate and life quality. Clinical stage, pathological type and therapeutic method were also important prognostic factors for the long term survival.

CONCLUSIONSurgery plus postoperative radiotherapy can improve the 5-year survival rate of soft tissue sarcoma.

OBJECTIVETo discuss the mechanism of scar hypertrophy in adenosine receptor A(2A) (A(2A) R) knockout mice.

METHODSAnimal models of hypertrophic scar were established in 12 A(2A) R knockout mice and 12 wild-type mice as control. The thickness and the size of transverse section of the hypertrophic scar were observed by H-E staining. The hydroxyproline (HYP) in the scar was measured colorimetrically. The TGF-beta expression was tested by Western blotting method.

RESULTSThe hypertrophic scar in wild-type mice was more severe than that in knockout mice. Compared with self-control, the increase of the thickness and the size of transverse section of hypertrophic scar was markedly higher in wild-type group than in the knockout group (P < 0.01). There was significant difference in HYP content between the two groups (P < 0.01). Compared with self-control, the increase of TGF-beta expression in wild-type group was much more than that in knockout group (P < 0.01).

CONCLUSIONSThe TGF-beta expression decreases in the A(2A) R knockout mice. The scar hypertrophy is also much less in the A(2A) R knockout mice.

Objective To investigate the current popularity of ERCP training in China.Methods A questionnaire-based survey was performed on a professional survey website.A total of 48 questions were designed,including personal information,training information,current status of ERCP performance and sug-gestions to ERCP training.The questionnaire was completed anonymously by physicians who fulfilled full-time ERCP training in any Chinese endoscopy center for at least 1 year before.Results A total of 464 phy-sicians,from all the regions of mainland China,among which 362 people completed all the questions.More than two thirds trainees thought that they had got fruitful training and 27.4% trainees had their ERCP vol-umes greatly increased and 64.3% trainees increased practice.According to related index,the physicians who were competent in routine ERCP performance were 84.5%,with outstanding operators of 12.2%.Con-clusion China has made great progress in the training program of ERCP technique in recent decades,but problems still remain such as various admission standard,insufficient training duration,incomprehensive program,as well as lack of evaluation and follow-up system.
