Objective To evaluate endoscopic ultrasonography (EUS) for diagnosis of gastric stromal tumors (GST) by analyzing EUS features of tumors with different invasive capacities.Methods Clinical data of 34 patients with GST were analyzed retrospectively.The tumors were classified according to Fletcher′s GIST biological behavior ranking system and the corresponding EUS features were analyzed.Results The mean maximal diameter of GST in this cohort was 6.7cm.The echo heterogeneity, big tumors size, irregular shape and ulceration were more common in tumors of high risk (P<0.05).Conclusion Tumor size, shape, echo quality and ulceration detected by EUS are useful features for pretreatment evaluation of GST, and can guide the choice of following managements.

Objective To observe the changes of systolic time interval after neonatal asphyxia and explore its relationship with clinical manifestation and prognosis. Methods Tow-dimensional and Doppler echocardiography were employed to detect tow - dimension parameters and left and right ventricular STI in 27 mild and 18 severe asphyxiated neonates as well as 14 normal controls and its relationship with clinical manifestation and prognosis was analyzed. Results There was no difference in cavity and thickness of heart and great arteries between normal and asphyxiated neonates. In acute stage mild and severe asphyxiated neonates had a shorter right ventricular ejection time (RVET) than normal neonates and a longer right ventricular prejection period (RPEP) was found in severe neonates than that in normal and mild asphyxiated neonates. Left ventricular preejection time (LPEP) was prolonged in comparison with normal neonates in acute stage and convalescence. There were more cases with increased RPEP/RVET in severe asphyxiaed group than those in mild and normal group in acute stage. The incidence of heart failure in acute stage and disability in late period was higher in cases with increased RPEP/RVET than that with normal RPEP/RVET. Conclusion Asphyxia has more severe damage to right ventricle than that to left ventricle. Cases with increased RPEP/RVET are prone to suffering from heart failure in acute stage and more likely to undergo disability in late period.

BACKGROUND: The fracture of femoral neck in adults is very common. Most of them can be cured by operation or conservative treatment, but a few can develop into old fracture. At present, there is no clear and effective treatment for old fracture of femoral neck in adults. OBJECTIVE: To explore the clinical effect of sartorius pedicle iliac bone flap combined with proximal femoral locking plate in the treatment of old femoral neck fracture in adults. METHODS: Twelve adult patients with old femoral neck fracture were treated with sartorius pedicle iliac bone flap combined with proximal femoral locking plate, 9 males and 3 females, aged 18-47 years, with an average age of 33. 5 years. Garden classification: Type I in 0 cases, type II in 1 case, type III in 7 cases, and type IV in 4 cases. All of them were incised by Smith Petersen (S-P) approach. The 2/3 sartorius pedicle iliac bone flap of the anterior superior iliac spine was chiseled with a bone knife, about 4. 0 cm×1. 0 cm×1. 0 cm in size. After reduction, the proximal femur was fixed with steel plate and screw. Finally, the sartorius pedicle iliac bone flap was implanted into the defect of the femoral neck and fixed. At 3, 6, 12, and 24 months after the operation, X-ray films were reexamined to evaluate the fracture healing and Harris score of hip joint was used to evaluate the recovery of hip joint function. RESULTS AND CONCLUSION: (1) Twelve patients were followed up for at least 24 months. (2) Harris scores of hip were significantly higher at 3, 6, 12, and 24 months after surgery (54. 4±6. 4, 68. 7±6. 8, 82. 3±4. 2, 90. 3±4. 6) than those before surgery (46. 3±6. 1) (P < 0. 05). (3) There were no complications, such as wound nonunion, infection, or venous thrombosis. Finally, 11 patients finally achieved bony healing at the fracture site. One patient had nonunion at 28 months postoperatively with avascular necrosis of the femoral head (ARCO stage IV), followed by artificial hip replacement. Harris score before operation was 38, and Harris score at 3 months postoperatively was 98. (4) The results show that the combination of sartorius pedicle iliac bone flap and proximal femoral locking plate is a good method for the treatment of old femoral neck fracture in adults, with high healing rate and low necrosis rate of femoral head.

Objective: To screen the active compounds in Sini Decoction showing the potential to inhibit tumor necrosis factor α (TNFα) to alleviate Doxorubicin (DOX)-induced heart failure. Methods: A chemical database of Sini Decoction was constructed from literature research. The generated pharmacophore models based on TNF-α used to screen active ingredients of Sini Decoction in the database by Discovery Studio 2.5. Molecular docking by Autodock 4.2 was adopted to demonstrate the hit compounds' affinities with TNFα. Furthermore, DOX-induced heart failure model on H9c2 cell line was constructed and cell viability was detected by CCK-8 to validate the therapeutic effect of potential active compounds. Results: The higenamine showed potential cardiovascular protective effect through virtual screening. And the activity was identified in vitro. Conclusion: In this study, we found that higenamine may inhibit TNF-α through virtual docking and validated that higenamine may have the potential of treatment for heart failure in the model of doxorubicin-induced myocardial toxicity to H9c2 cells.

Objective:To investigate sinomenine (Sinomenine,SIN) effect on RAW264.7 cells polarization to M1 or M2 phenotype induced by lipopolysaccharide (LPS) or interleukin-4 (IL-4) .Methods:RAW264.7 cells were induced to polarize to M1 by LPS ,and to M2 by IL-4.Sinomenine effects on LPS or IL-4 induced macrophages:TNF-αand IL-10 secretion induced by different condition were detected by Enzyme linked immunosorbent assay (ELISA);The expression level of mRNA of Arginase1(Arg-1),Nitric oxide synthase(iNOS),suppressor of cytokine signaling protein-2(SOCS2) and suppressor of cytokine signaling protein-3(SOCS3) of M1/M2 phenotypes were detected by real time PCR respectively.Results:Sinomenine inhibited the increase of TNF-αsecretion,iNOS and SOCS3 mRNA expression level induced by LPS.Sinomenine inhibited the increase of IL-10 secretion and Arg-1 mRNA expression level induced by IL-4,but SOCS2 mRNA expression level was not affected by Sinomenine.Conclusion: Sinomenine can inhibite the macrophage polarization to M1 and M2 induced by LPS and IL-4.Sinomenine plays a regulatory role on imbalance of M1/M2,and is conducive to maintain the dynamic balance.

Objective To investigate the effect of berberine on the polarization of mice RAW264.7 macrophages induced separately by lipopolysaccharide (LPS) and interleukin-4 (IL-4). Methods Mice RAW 264.7 macrophages cultured in vitro were divided into model group, medication group, and blank control group. Both model group and medication group were given either LPS (in final dose of 100 ng/mL) or IL-4 (in final dose of 10 ng/mL). Additionally, the medication group was treated with berberine in final dose of 20 μmol/L. The blank control group was given the same volume of phosphate buffered saline ( PBS). Real-time fluorescence quantitative polymerase chain reaction (PCR) was used to detect the mRNA expression of arginase-1 (Arg-1), inducible nitric oxide synthase ( iNOS) , suppressor of cytokine signaling2 ( SOCS2) and SOCS3. Enzyme-linked immunosorbent assay (ELISA) was used to determine the contents of tumor necrosis factor alpha (TNF-α) and IL-10. Results The content of TNF-αand the mRNA expression levels of iNOS and SOCS3 in macrophages induced by LPS were increased, and then were down-regulated by berberine (P<0.05 or P<0.01) . The content of IL-10 and the mRNA expression level of Arg-1 in macrophages induced by IL-4 were increased, and then were down-regulated by berberine ( P<0.05), but berberine had no effect on the mRNA expression level of SOCS2 ( P>0.05). Conclusion Berberine has an effect on inhibiting the M1 and M2 polarization of macrophages in vitro, suggesting that berberine may play a regulatory role in the dynamic balance of M1/M2.

Objective To observe the anti-inflammatory effects of three kinds of aconine from Radix Aconiti Lateralis Preparata ( Fuzi) on macrophages, as well as the effects of their combination with sinomenine. Methods The effect of three monoester alkaloids from Fuzi, benzoylaconine ( BAC) , benzoylmesaconine ( BMA) and benzoylhypaconine ( BHA) , on RAW264.7 cells proliferation was detected by cell counting kit 8 (CCK8) in vitro. RAW 264.7 macrophage cells were stimulated by lipopolysaccharides (LPS) and then treated with different concentrations of BAC, BMA, and BHA. Tumor necrosis factor alpha ( TNF-α) and interleukin 6 (IL-6) secreted by RAW264.7 cells were measured by enzyme-linked immunosorbent assay (ELISA) . The anti-inflammatory effects of three monoester alkaloids combined with sinomenine were evaluated by Zhengjun Jin Q method. Results The concentrations of TNF-α and IL-6 secreted by LPS-stimulated RAW264.7 cells were increased significantly ( P<0.01) , and then were inhibited by BAC ( 20, 30 μmol/L) , BMA ( 40, 80, 160μmol/L) and BHA ( 40, 80, 160 μmol/L) significantly ( P<0.01) . Antagonistic effects were present when 30 μmol/L of BAC or 160 μmol/L of BMA or 160 μmol/L of BHA was respectively used together with 100 or 300 μmol/L of sinomenine (Q<0.85). Conclusion The three kinds of monoester alkaloids from Fuzi exert anti-inflammatory effect on macrophages, and the effective dose of BAC is lower than that of BMA and BHA. The combination of BAC, BMA or BHA at the analyzed dosage with sinomenine has antagonistic effect.
