Objective: To observe the efficacy of acupoint sticking with Jianpi Tongjing Zhitong ointment in the treatment of functional dyspepsia due to liver-qi stagnation and spleen deficiency and its effect on serum 5-hydroxytryptamine (5-HT) and ghrelin contents. Methods: One hundred patients with functional dyspepsia due to liver-qi stagnation and spleen deficiency were divided into a treatment group and a control group by the random number table method, with 50 cases in each group. The treatment group received acupoint sticking with Jianpi Tongjing Zhitong ointment and the control group was treated with mosapride citrate orally. Patients were treated for 4 weeks as a course. The therapeutic efficacy was compared after one-course treatment and the differences in gastric emptying rate, and serum 5-HT and ghrelin contents between groups were compared before and after treatment. Results: The total effective rate was 79.6％ in the control group and 89.4％ in the treatment group, showing significantly different between groups (P<0.05). After treatment, the gastric emptying rate and serum ghrelin content of the two groups increased significantly, and the serum 5-HT content decreased significantly, the intra-group differences were significant (all P<0.01). After treatment, the gastric emptying rate and serum ghrelin content were significantly higher in the treatment group than those in the control group, while the serum 5-HT was significant lower in the treatment group, the inter-group differences were significant (all P<0.05). A negative correlation (r=-0.59) was observed between serum 5-HT content and gastric emptying rate, and a positive correlation (r=0.64) was observed between serum ghrelin content and gastric emptying rate, showing statistical significance (all P<0.01). Conclusion: Acupoint sticking with Jianpi Tongjing Zhitong ointment has a remarkable clinical efficacy in treating patients with functional dyspepsia due to liver-qi stagnation and spleen deficiency and is able to influence the secretion of serum 5-HT and ghrelin. Improving the gastrointestinal motility through the regulation of related brain-gut peptides is suggested as an underlying mechanism for this therapy.

We enrolled 60 patients with American Association of Anesthesiologists grade Ⅰ - Ⅱ undergoing unilateral total knee arthroplasty. All patients received combined epidural and spinal anesthesia,and a nerve stimulator was used to guide placement of a femoral nerve catheter. Patients were divided into three groups according to the catheter location on X-ray : psoas muscle group ( n = 18 ), iliacus muscle group (n = 19) and local group (n =23). Visual analog scale (VAS) pain scores were recorded at rest and with movement at 4, 24 and 48 h postoperatively and sensory blockade of the femoral, obturator and lateral femoral cutaneous nerves was recorded at 24 h.There were no significant differences in femoral nerve blockade among the three groups. Obturator nerve blockade was significantly better in the psoas muscle group than in the iliacus muscle and local groups, and was also better in the local group than in the iliacus muscle group. There was no significant difference in lateral femoral cutaneous nerve blockade between the psoas muscle and iliacus muscle groups, but there was better blockade in both these groups than in the local group. At 4 h postoperatively, VAS pain scores at rest were significantly lower in the psoas muscle group than in the iliacus muscle and local groups, but there were no significant differences in VAS pain scores with movement among the three groups. At 24 and 48 h postoperatively, VAS scores at rest and with movement were significantly lower in the psoas muscle group than in the iliacus muscle and local groups.

Objective To study the (-)-epigallocatechin-3-gallate (EGCG) function on the proliferation of T cells derived from the peripheral blood and synovial fluid of rheumatoid arthritis (RA) and RA-related cytokine levels and the role of EGCG on RA synovial fibroblasts (FLS) proliferation was investigated. Methods ① Mononuclear cells from RA peripheral blood (30 cases) and synovial fluid (23 cases)were isolated. Blank group, negative control group, positive control methotrexate (MTX) group and therapeutic group with three different concentrations of EGCG were set up. Incorporated isotope 3H was used to test T cell proliferation from RA-PBMC and SFMC. ELISA assay was used to test cytokine (TNF-α, IFN-γ, IL-1, IL-6 and IL-17A) levels. ② MTT assay was used to test FLS proliferation from RA synovial tissue (8 cases).Results ① The CPM value of the high-dose group of EGCG in the peripheral blood and synovial fluid of RA patients was [ ( 15 136±2910), ( 11 587±3135 ) ], which was declined significantly than the control group (42856±2127) (P＜0.01). The levels of TNF-α, IFN-γ, IL-1, IL-6 and IL-17A in the high-dose group of EGCG in the peripheral blood were [(321±13), (298±20), (132±12), (197±7), (59±8) pg/ml], which were decreased significantly than those of the control group [ (458±28), (505±26), (346±28), (405±25),(109±13) pg/ml ] (P＜0.05 or P＜0.01 ). The levels of TNF-o, IFN-γ, IL-1, IL-6 and IL-17A in the highdose group of EGCG in the synovial fluid were [(41.4±2.9), (182±16), (56.3±11.0), (34.2±1.9), (44±8)pg/ml ], which was decre-ased significantly than the control group [ ( 388.3± 19.3 ), (469±20), ( 104.2±17.8 ),( 114.5±4.8), ( 104±11 ) pg/ml] (P＜0.05 or P＜0.01 ). ② The level (A) of the high-dose group of EGCG in the FLS was (0.08±0.02), which was declined significantly than the blank group (0.27±0.04) (P＜0.05).Conclusion ① In vitro EGCG can inhibit T cell proliferation from peripheral blood and synovial fluid of RA patients and the TNF-α, IFN-γ, IL-1, IL-6 and IL-17A secretion are decreased. ② In vitro EGCG can inhibit the proliferation of RA FLS.

Objective To investigate the effect of metformin on the proliferation and apoptosis in human pancreatic cancer cell line CFPAC-1,and to explore the potential mechanism.Methods Human pancreatic cancer CFPAC-1 cells were cultured in vitro,and were treated with metformin at different concentrations (1,2.5,5,10,20,40,60 mmol/L) for different durations (24 h,48 h and 72 h),and cells without treatment were considered as control group.Cell proliferation was evaluated by CCK-8,cell cycle was determined by flow cytometry,apoptosis was determined by Annexin V/PI double staining method,and Western blot was used to detect the protein expression of p-AMPK,FAS,cyclin D1,Bcl-xl,Bax,caspase-3 and survivin.Results Metformin could inhibit the proliferation of CFPAC-1 cells in a time and dose dependent manner.Forty-eight hours after 40 mmol/L metformin treatment,the proportion of CFPAC-1 cells in phase G0/G1 was significantly increased [(65.93 ± 0.27)％ vs (42.89± 1.02)％],and the proportion of CFPAC-1 cells in phase G2/M,S was significantly decreased [(22.01 ± 2.95) ％ vs (38.28 ± 4.93) ％,(13.58±0.43)％ vs (20.12 ± 3.38)％],and the difference between the two groups was statistically significant (P ＜0.05).The apoptosis rate was increased from (3.01 ± 0.49) ％ to (32.97 ± 3.19) ％,(P ＜ 0.05) ; and the expression of p-AMPK,Bax,and caspase-3 was increased,while the expression of FAS,cyclin D1,Bcl-xl,survivin were decreased.Conclusions Metformin can inhibit proliferation and promote apoptosis of CFPAC-1 cells mainly by activation of AMPK pathway,and down-regulation of FAS,cyclin D1,survivin and Bcl xl/Bax ratio,as well as up-regulation of caspase-3.

BACKGROUND:Currently, human umbilical cord derived-mesenchymal stem cel s are mainly for local transplantation, which has some shortcomings, such as large trauma, bleeding, complications, that limit its widespread application in clinical practice. OBJECTIVE:To investigate the feasibility of intravenous transplantation of human umbilical cord derived-mesenchymal stem cel s for repair of spinal cord injury. METHODS:Eighty Wistar rats with spinal cord hitting were divided into five groups:blank control group with no transplantation (n=10), DMEM local transplantation group (n=15), DMEM intravenous transplantation group (n=15), cel local transplantation group (n=20), cel intravenous transplantation group (n=20). The functional recovery of spinal cord injury was observed with Basso, Beattie and Bresnahan scores at regular time as wel as hematoxylin-eosin staining and immunohistochemistry staining. RESULTS AND CONCLUSION:During 1 day to 2 weeks after transplantation, there was no significant difference in the Basso, Beattie and Bresnahan scores between the five groups;within 4-12 weeks after transplantation, the Basso, Beattie and Bresnahan scores were significantly higher in the two cel transplantation groups than the other three groups, but there was no difference between these two cel transplantation groups (P>0.05). Histological observation showed that the number of voids and glial scars was less in the cel local transplantation group and cel intravenous transplantation group compared with the other three groups, and there was also no difference between the two cel transplantation groups. These results indicate that the intravenous transplantation of human umbilical cord derived-mesenchymal stem cel s is similar to the local transplantation in the repair of acute spinal cord injury, which is simple and avoids secondary injuries and various complications. It is recommended that this method provide a new approach for cel transplantation.
