Objective To evaluate the value of MRI in acute ankle distortion without evidence of fracture. Methods The MRI appear-ances of 21 cases with acute trauma in the ankles were retrospectively analyzed,focusing on the presence or absence injuries of lateral collat-eral ligamentous complex,bone and osteochondral lesions,MRI was performed within 48 h of trauma. Results Bone bruise was observed in 15 patients. There were injuries of the lateral ligaments in 4 cases and the medial ligaments in 1 case. Injury of the osteochondral lesion was in 5 cases and Achilles tear was in 3 cases. Conclusion MRI have diagnostic value for acute ankle injury.

Objective To observe the effect of Tanggankang on the expression of CREB in diabetic-fatty liver rats;To investigate the mechanism of Tanggankang. Methods STZ and feeding high fat forage induced diabetic rats were randomly divided into model group, Huganning group, Tanggankang high dose group, Tanggankang medium dose group, Tanggankang low dose group, 10 rats in each group, with 10 normal rats as control. After 12 weeks of drug intervention, rats were killed, the livers were removed, and the expression of CREB was detected by Western blot. Results Compared with normal group, the level of CREB of model group was significantly decreased (P<0.01). Compared with model group, Tanggankang low, medium and high dose group significantly decreased the level of CREB (P<0.01). Conclusion Tanggankang may play an active role in glucose and lipid metabolism by affecting the expression of CREB.

Objiective To evaluate the histocompatibility of gelatin-bletilla/Salvia-miltiorrhiza i material and to discuss the appropriate concentration of salvia-miltiorrhiza in the material. Method Salvia-miltiorrhiza together with gelatin and bletilla was used to make a kind of porous membranes. A total of 175 rats were divided randomly (random number) into 5 groups ( n = 35 in each). The porous membranes containing salvia-miltiorrhiza material in different concentrations of 1, 2, 4, and 5 mL/100 g were implanted subcutaneously into the rats of the four experimental groups, respectively. The gelatin-bletilla material without salvia-miltiorrhiza was implanted into the rats of control group. In 1, 3, 7, 14, 21, 28 and 56 days after implant, the materials were taken out of the bodies of the rats, separately. The material implanted for 1, 3, 7 and 14 days were observed with immunohistoche-mistry. Results In the area of implant, no noticeable inflammation or other was found. The implanted materials were degraded and entirely absorbed in vivo in 8 weeks. The salvia-miltiorrhiza in concentration of 2 mL/100 g in vivo promoted the angiogenesis most significantly. Conclusions The gelatin-bletilla/salvia-miltiorrhiza material has excellent histocompatibility and the appropriate concentration of salvia-miltiorrhiza in material is 2 mL/100 g.

Objective To study the therapeutic effect of the hip surface replacement on osteoarthrithis of hip.Methods The clinical data of 5 cases with osteoarthrithis of hip treated by hip surface replacement were retrospectively reviewed.Results Patients were followed up for an average period of 2.1 years(6～28 months).There were no femoral neck fracture,no dislocation,no infection in all patients.The average Harris score was 85.4(48.3 scores before surgery).Postoperatively quality of life improved obviously.Conclusion The therapeutic effect on osteoarthrithis of hip treated by the hip surface replacement is satisfactory,and the quality of patient's life can be improved,espcially for the youth.

Objective To evaluate the effects of locking calcaneal plate in the treatment of SandersⅢ～Ⅳcalcaneal fractures.Methods 15 feet of 12 patients of SandersⅢ～Ⅳcalcaneal fractures received the treatment of internal fixation reduction with locking calcaneal plate and hone graft.Results All the patients were followed up for 4 to 21 months(average 11 months) with the results that according to Maryland foot score,4 feet were reported ex- cellent,6 good,1 average and 1 poor,with total excellent and good rate of 83.3 %.Conclusion Using locking cal- caneat plate in the treatment of complicated calcaneal fractures was proved to be a good method and had satisfactory effects.

Sugarcane stem is an ideal organ for producing foreign pharmaceutical proteins and chemicals by genetic engineering.A perfect promoter driving foreign gene to express strongly and specifically in sugarcane stem is necessary for this purpose.In order to isolate a Sugarcane stem-specific promoter,a fragment of 1968bp nucleotide sequence(Ppst2a)upstream 5' of sugarcane pst2a gene,which was demonstrated to express specifically in sugarcane stem previously was isolated by using chromosomal walking.Bioinformatical analysis of this sequence shows that the sequence contains some typical elements of a promoter.To identify the stem-specific of this promoter,a construct was derived from pCAMBIA1301,which original CaMV 35S promoter was replaced by the 1968bp nucleotide sequence,and named as pCAMBIA1900.Transformations of pCAMBIA1900 and pCAMBIA1301 to leaves and stem pieces of sugarcane were carried out by using particle bombardment.The transient expression of gus showed that the gus expressed specifically in sugarcane with a little higher level compared with CaMV 35S.It is the first report that pst2a promoter is a potential stem-specific promoter which can further be used in transgenes into sugarcane.

AIM: To compare the safety and efficacy of conjunctival autograft transplant ( CAT ) and limbal - conjunctival autograft transplant (LCAT) for primary pterygium.
METHODS: In this prospective, randomized and controlled clinical study, 120 patients ( 120 eyes ) diagnosed with primary pterygium were collected in NO. 474 Hospital of Chinese PLA from January 2014 to January 2015. The 120 patients enrolled in the study in turn, and divided into two group by the odd and even number. The odd number underwent CAT and the even number underwent LCAT.
RESULTS:One hundred and seven patients (107 eyes) completed the follow-up of 1a, including 54 patients (54 eyes) from the CAT group and 53 patients (53 eyes) from the LCAT group. Four patients (4 eyes, recurrence rate 7. 4%) in the CAT group and 2 patients ( 2 eyes, recurrence rate 3. 8%) in the LCAT group developed recurrence. However, there were no significant in recurrence rate between CAT group and LCAT group (P =0. 678).
CONCLUSION: CAT and LCAT might be both effective treatment for primary pterygium for reducing the recurrence rate of pterygium. However, LCAT is the optimal surgical method for primary pterygium.

OBJECTIVETo investigate the clinicopathological features of testicular malignant Leydig cell tumor (TMLCT) and improve the non-invasive diagnosis of the disease.

METHODSWe retrospectively analyzed the clinicopathological data on a case of TMLCT, detected the circulating tumor cells (CTC) in the peripheral venous blood, and reviewed the related literature.

RESULTSThe patient, a 47-year-old male, underwent radical orchidoepididymectomy under general anesthesia. Postoperative pathology confirmed the lesion to be TMLCT, which was mainly composed of Leydig cells and suspected with vessel carcinoma embolus. Immunohistochemistry showed the tumor cells to be positive for α-inhibin, Ki67, CD30, vimentin, EMA, and PLAP, but negative for CK, CK7, S100, CD10, SMA, Des, AFP, hCG, CEA, CK19, CD117, Oct-4, LCA, CD20, Pax-5, CD3, and CD43. Two CTCs were detected in the peripheral venous blood. The patient received 3 courses of chemotherapy for retroperitoneal multiple lymph nodes metastasis post-operatively. Subsequent CT imaging manifested no obvious reduction of the retroperitoneal lymph nodes and consequently the patient again underwent retroperitoneal lymphadenectomy and cryoablation. At 8 months after treatment, CT examination revealed notably enlarged retroperitoneal lymph nodes with the right adrenal gland evidently invaded.

CONCLUSIONTMLCT is an extremely rare sex-gonad stromal tumor with high malignancy and poor prognosis, and CTCs may be used for its early diagnosis and prognostic prediction.
