MRI findings and its correlation with prognosis of patients were analyzed. Results　Among the 90 cases of spinal cord injury, incomplete and complete transection of spinal cord was found in 14 cases (13.2%), spinal cord edema in 11 (10.4%), intraspinal cord hemorrhage in 27 (25.5%), compression and dislocation in 27(25.5%), malacia in 16(15.1%), and atrophy in 11(10.4%). Conclusion　From the morphologic and pathological changes of spinal cord MRI can not only direct the option of treatment protocols, but may also evaluate the prognosis of spinal cord injuries. Demonstrated by MRI, it suggests that.

Objective To study the effect of Xiaoaiping injection on Caov-3 human ovarian cancer cells and its mechanisms. Methods After treatment with Xiaoaiping injection, viability of Caov-3 cells determined by MTT method. Phase contrast microscopy was used to observed the morphological changes of Caov-3 cells. Cell cycle was assessed by FACS. Cell signaling pathway protein-Akt and pAkt, and cell cycle associated protein-p27 were measured by western blot. Results Xiaoaiping injection inhibited the growth of Caov-3 human ovarian cancer cells in a dose and time dependent manner. Xiaoaiping injection induced G0/G1 phase arrest of Caov-3 cells, accompanied by pAkt down-regulation and p27 up-regulation. Conclusion Xiaoaiping injection can inhibit the proliferation of Caov-3 human ovarian cancer cells by inhibiting PI3K/Akt signaling pathway.

Objective To investigate the effects of Chinese medicine HUOXUESHENGJI(promoting blood flow and tissue regeneration) on the oxidative stress in rat skeletal muscles after acute contusion.Methods Seventy two male SD rats were randomly and equally divided into three groups:(1)Chinese medicine HUOXUESHENGJI group(A),(2)physiological saline group(B),(3)natural healing group(C),and(4)blank control group(D).The muscle contusion was produced at the gastrocnemius by specific device;Local injection at the injured site with Chinese medicine HUOXUESHENGJI in group A;local injection with physiological saline instead of HUOXUESHENGJI in group B,and natural healing group served as control.The muscles were sampled at day 1,4,7 and 14 respectively after contusion,and then the MDA and the activities of antioxidant enzymes(CAT,SOD and GSH-px)in gastrocnemius were investigated.Results As compared with the group B and group C,SOD and GSH-px activities in group A were significantly increased after contusion(P0.05).The con-centrations of MDA in group A were lower than that in group B and group C at day 4 and day 7 after contusion(P

Objective To compare the clinical results of Endobutton and Rigidfix graft fixation at the femoral tunnel after ACL reconstruction with hamstring autografts.Methods 48 patients accepting ACL reconstruction with hamstring autografts were retrospective studied.According to different fixation adopted at the femoral tunnel,they were divided into group A(24 patients,with Rigidfix cross pin)and group B(24 patients,with Endobutton).All cases were fixed with Intrafix interference screw and Spiked Washer screw at the tibial tunnel.The average follow-up time was 27 months.KT-1000 arthrometric measurement and the IKDC,Lysholm,Tegner scores were used for evaluation.The diameter of bone tunnel was also measured by MRI.Results Tunnel widening were found in both groups,but the increase of both the femoral and tibial tunnels in group B were significantly greater than group(P

Objective To explore the role of transforming growth factor (TFG) -β and matrix metalloproteinases( MMPs) in the development of frozen shoulder. Methods Twenty-four patients who underwent shoulder arthroscopy were included, and were divided into frozen shoulder group (n = 12) and control group ( n = 12; n = 2 for shoulder instability, n = 5 for rotator cuff tear and n = 5 for subacromial impingement) . Joint capsule tissues at the rotator cuff interval were obtained, and the expression of TGF-β, MMP-1, MMP-2, MMP-3, MMP-9 and MMP-12 mRNA and protein was detected by Real-time PCR and Western blotting, respectively. Results The expression of TGF-p mRNA in frozen shoulder group and control group was 3.36 × 10~4 ±2.18 × 10~3 and 1.85 × 10~4 ±3.31×10~3, respectively, the expression of TGF-p protein was 1.55 ± 0.33 and 1.13 ±0.21, respectively, and there were significant differences between these two groups (P < 0.05). The expression of MMP1, MMP2, MMP3, MMP9 and MMP12 mRNA and protein in frozen shoulder group was significantly higher than that in control group(P <0.05) . Conclusion The higher expression of TGF-β and MMPs in joint capsule of frozen shoulder may be associated with the development of frozen shoulder.

Objective To evaluate the guidance value of capsule endoscopy and clinical scoring system in risk stratification for acute upper gastrointestinal bleeding (AUGIB) .Methods 24 patients presenting to the emergency room with AUGIB ,were randomly divided into two groups (12 cases in each group) .Pre‐Endoscopic Blatchford and Rockall scores were calculated for all pa‐tients .All patients underwent endoscopy(EGD) within 24 hours .The timing of EGD was based on clinical scores in control group , and on VCE in observation group .Positive VCE was defined as red blood ,clot or coffee grounds .Mean Rockall and Blatchford scores for all 24 patients were compared to differentiate high‐and low‐risk patients .Rockall and Blatchford scores were also com‐pared with VCE findings .Results A total of 13 out of 24 patients had high‐risk stigmata on EGD ,with the mean Rockall and Blatchford scores of 3 and 13 respectively .Meanwhile ,the mean Rockall and Blatchford scores of the other 11 patients were 2 and 11 .There was no statistically significant difference between the Blatchford scores of the two groups(95% CI:5 .2‐1 .4 ;P=0 .23) . Also there was no statistically significant difference between the Rockall scores of the two groups(95% CI:2 .2‐0 .3;P=0 .12) .In the subgroup of 12 patients who underwent VCE ,9/12 had positive findings confirmed at EGD afterward ,compared with the other 3 patients with negative VCE and endoscopy .Conclusion Both the Rockall and the Blatchford scores are not accurate to predict the degree of risk in patients with AUGIB identified at EGD .However ,VCE is sensitive and specific enough to a better risk stratifica‐tion tool .

Objective To investigate the expression of MIF in PBMC, sera and lacrimal fluid samples in patients with AD, and study the diagnostic significance of MIF in AD. Methods Forty-three AD patients (11 mild AD patients,23 moderate AD patients, 9 severe AD patients classfied by SCORAD index)and 31 age- and sex-matched healthy control subjects were recruited. Real-time RT-PCR was employed to analyze the expression of MIF mRNA in PBMC. ELISA was performed to detect the concentrations of MIF in sera and lacrimal fluid samples. Results AD patients had significantly higher levels of MIF mRNA in PBMC than normal controls [7.46 (3.38-8.90) vs 1.67 ( 1.24-2.45 ), Z=-6.141, P ＜ 0.05]. The concentrations of MIF in sera and lacrimal fluid samples in AD patients were also markedly higher than those of normal controls [serum 36. 32( 11.89-43.80) μg/L vs 7.89(6.13-9.54) μg/L, Z = -6.180,P <0.05; lacrimal fluid 12.66(2.01-20.12) μg/L vs 0.85(0.77-1.06) μg/L, Z = -4.118,P <0.05]. MIF mRNA levels were 2.35 ( 2.12-2.49 ) , 7.83 ( 6. 54-8.90 ) and 8.76 ( 8.22-9.73 ) in mild, moderate and severe AD respectively, and the expression was higher in moderate and severe AD than in normal controls (Z= -6.237, -4.520,P ＜0.05). MIF serum concentrations were 8.98(7.90-10.51) μg/L, 36.50 (29.78-43.23) μg/L and 45.70(41.27-48. 84) μg/L in mild, moderate and severe AD respectively, and the differences were significant in moderate and severe AD compared to normal controls ( Z = - 6.238,- 4.521, P < 0.05 ). The lacrimal fluid MIF oncentrations were 1.10 ( 0.83-1.35 ) μg/L, 12.66 ( 9.76-15.87) μg/L and 24. 65 ( 19.29-30.94) μg/L in mild, moderate and severe AD respectively. Similarly,they increased significantly in moderate and severe AD compared to normal controls (Z = -4.062,- 3.372, P ＜ 0.05 ). In moderate and severe AD, MIF mRNA levels in PBMCs and MIF concentrations in sera and lacrimal fluid samples were all positively correlated with the severity of AD ( r = 0.395, 0.404,0.515, P < 0.05 ). Conclusions The expression of MIF in PBMCs, sera and lacrimal fluid samples is higher in different course of AD. MIF can serve as a useful laboratory parameter for evaluation of AD activity and severity.

This study aimed at exploring the economic operation and developing trend of county-level public TCM hospitals in Guangxi Province,promoting the comprehensive reform of county-level public hospitals with feasible countermeasures and suggestions.In this study,forty-seven county-level public TCM hospitals were involved in the analysis of their economic operations and benefits by constituent ratio analysis,ratio analysis and trend analysis.As a result,the average gross income of the hospitals exceeded the total expenditure with a slight surplus.Drug income contributed the biggest share of the medical income,while the ratio of Chinese drug income to the medical income was increasing year by year.The debt ratio increased from 38.7％ in 2009 up to 44.6％ in 2013,being over 30％ in this period.In conclusion,it was demonstrated that problems were found in the lack of financial assistance,the low efficiency of economic management and the increasing average medical charges,which should be addressed by increasing investments to TCM hospitals,strengthening the performance appraisal and adjusting the charges of TCM medical services.
