Objective:To prove the feasibility and validity ofXing Nao Jing acupoint-injection (XNJ-AI) at Fengchi (GB 20) for pseudobulbar palsy caused by ischemic stroke (PBP-IS).
Methods:An assessor-blinded, two-parallel-group, randomized controlled trial was conducted, and the patients with PBP-IS were recruited and randomly divided into two groups. Patients in the control group received oral aspirin (100 mg per day for 2 weeks). In addition to oral aspirin; patients in the treatment group received XNJ-AI at Fengchi (GB 20), once a day, for two weeks. The primary outcome was assessed by the water-swallowing test (WST). Thromboxane B2 (TXB2) and 6-keto-prostaglandin F1a (6-keto-PGF1a) in plasma were measured before and after the treatment.
Results:In the treatment group, the percentage of swallowing function no less than grade 3 before and after the treatment was 32% and 88%, respectively; in the control group, it was 28% and 76% before and after the treatment, respectively; the difference after the treatment between the two groups was statistically significant (P<0.05). There were statistical differences between pre- and post-treatment levels of plasma TXB2and 6-keto-PGF1αin the two groups (bothP<0.05). After the treatment, there were significant differences in the levels of plasma TXB2 and 6-keto-PGF1α between the two groups (bothP<0.05).
Conclusion:XNJ-AI at Fengchi (GB 20) can improve the patients’ swallowing function and balance the levels of TXB2 and 6-keto-PGF1α in plasma.

NOK is a newly identified receptor protein-tyrosine kinase (PRTK) molecule that can promote tumorigenesis and metastasis. Previous data showed that NOK could activate the phosphatidylinositol 3'-kinase (PI3K) pathway in stable BaF3 cells. But how does NOK activate PI3K in cells remains unknown. It was showed that NOK physically interacted with the PI3K downstream effector Akt and enhanced its activation in human embryo kidney 293T (HEK293T) cells. Deletion mapping indicated that protein kinase B (Akt) was able to directly contact with the kinase domain of NOK. Inactivating the Akt kinase domain significantly reduced the intermolecular interaction between NOK and Akt, while constitutively active mutant of Akt apparently had a stronger interaction with NOK. NOK did not have an additive effect on insulin-mediated Akt activation. Overall, the results indicate that NOK might complex with Akt and directly activate PI3K/Akt signaling pathway.

This study is to investigate the role of endogenous CSE/H2S in regulating apoptosis of HepG2 cells. MTT and Trypan blue assay were performed to determine the effect of CSE inhibitor PAG and CSE siRNA on proliferation of HepG2. Production of H2S from HepG2 cells was assessed spectrophotometrically using N, N-dimethyl-p-phenylenediamine-dihydrochloride. Cells apoptosis was detected by means of double staining of Hoechst 33342 and PI with Array Scan V(TI)HCS600 High-Contents. Dihydroethidine (DHE) and 2', 7'-dichlorodihydrofluorescein diacetate (DCFH-DA) assay was used to determine intracellular superoxide anion and ROS level. Reduced glutathione (GSH) was determined by OxiSelect Total Glutathione Assay Kit. Recombinant plasmid pcDNA 3.1/myc-His(-)-CSE was constructed and transfected into 293T cells to rescue the ROS and GSH level to further investigate the effect of CSE/H2S on ROS and GSH. Western blotting was performed to test the effect of CSE siRNA on expression of activated caspase 3 and p-AKT and Nrf2 protein. The results showed that PAG and CSE siRNA could significantly decrease the production of H2S in HepG2 cells and inhibit the proliferation of HepG2 cells at a dose-dependent and time-dependent manner, respectively. PAG and CSE siRNA could promote the cell apoptosis of HepG2 cells. Moreover, PAG and CSE siRNA induced increased ROS generation and depletion of the critical antioxidant GSH and recombinant plasmid pcDNA 3.1/myc-His(-)-CSE rescued the level of ROS and GSH. Meanwhile, CSE siRNA increased the expression of activated caspase 3, but CSE siRNA did not affect the expression of p-AKT and Nrf2. These results suggested that the CSE/H2S pathway was involved in suppression of HepG2 cell growth and promoted apoptosis of HepG2 cells in an oxidative stress-dependent manner.

Objective To investigate the effect of medium- and long-chain triacylglycerols on body fat accumulation in subjects with different levels of hypertriglyceridemia. Methods 112 subjects with hypertriglyceridemia were randomly divided into two groups: one group was demanded to adopt long-chain triacylglycerol (LCT) oil as their daily use and the other one to medium- and long-chain triacylglycerol (MLCT) oil for consecutive 8 weeks. Anthropometric measurements of body weight, body mass index (BMI), waist circumference (WC), hip circumference(HC), WHR (ratio of WC/HC), triceps skinfold thickness (TSF), subscapular skinfold thickness (SSF), body fat weight, body fat percentage, total fat area, visceral and subcutaneous fat area in abdominal and concentration of blood triglycerides (TG) were measured at the initial and final time of the study. In both groups, the cutpoint of TG 2.3 mmol/L was used to distinguish the different levels of hypertriglyceridemia. Results Compared with LCT group, body weight, BMI, WC, body fat weight, total fat area, visceral and subcutaneous fat area in abdominal in those of TG≤2.3 mmol/L in MLCT group were significantly decreased (P 2.3 mmol/L between the two groups. Furthermore, the concentrations of TG in hypertriglyceridemia subjects of different levels in MLCT group were both significantly lower than those in LCT group after 8 weeks (P 2.3mmol/L.
