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.

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.

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.

Objective To evaluate the effect of hydrogen-rich saline on the expression of phosphor-p38 mitogen-activated protein kinase (p-p38MAPK) during cerebral ischemia-reperfusion (I/R) in rats.Methods Seventy-two adult male Sprague-Dawley rats,weighing 220-250 g,were randomly divided into 3 groups (n =20 each) using a random number table:sham operation group (group S),I/R group and hydrogen-rich saline group (group I/RH).Cerebral ischemia was induced in chloral hydrate-anesthetized rats by 2 h middle cerebral artery occlusion in I/R and I/RH groups.The artery was only exposed but not occluded in group S.At 3 days before operation and immediately after onset of reperfusion,hydrogen-rich saline (0.6 mmol/L) 10 ml/kg was intraperitoneally injected in group I/RH,while the equal volume of normal saline was given in S and I/R groups.Neurological deficits were blindly assessed and scored at the end of 24 h reperfusion.The animals were then sacrificed,and brains were removed for microscopic examination and for determination of the cerebral infarct size (by TTC),brain water content,cell apoptosis (by TUNEL),and expression of p38MAPk and phosphor-p38MAPK (p-p38MAPK) (by immunohistochemistry and Western blot).Apoptosis index was calculated.Results Compared with group S,neurological deficit score,apoptosis index,brain water content and cerebral infarct size were significantly increased,and the expression of p38MAPK and p-p38MAPK was up-regulated in I/R and I/RH groups.Compared with group I/R,neurological deficit score,apoptosis index,brain water content and cerebral infarct size were significantly decreased,and the expression of p38MAPK and p-p38MAPK was down-regulated in group I/RH.The pathological changes of cerebral tissues were significantly attenuated in group I/RH as compared with group I/R.Conclusion Hydrogen-rich saline can reduce cell apoptosis through inhibiting p-p38MAPK expression,thus attenuating cerebral I/R injury in rats.

Objective To investigate the blood-saving effect of controlled low central venous pressure (CLCVP) in different types of hepatectomy.Methods Ninety ASA physical status Ⅰ or Ⅱ patients of both sexes,aged 37-76 yr,weighing 40-75 kg,undergoing elective hepatectomy,were divided into 6 groups according to the surgical approach and whether CLCVP was used during surgery (n =15 each):CLCVP1-3 groups and nonCLCVP1-3 groups (NCLCVP1-3 groups).The standard hepatectomy,half liver resection and irregular hepatectomy were performed in CLCVP1-3 groups,respectively,with CLCVP.The standard hepatectomy,half liver resection and irregular hepatectomy were performed in NCLCVP1-3 groups,respectively,without CLCVP.In CLCVP1-3 groups,from skin incision to the end of liver resection,CVP was maintained ≤ 5 cm H2 O through adjustment of the position,fluid restriction and iv infusion of nitroglycerin,and norepinephrine was infused simultaneously to maintain mean arterial pressure ≥ 60 mm Hg.In NCLCVP1-3 groups CVP was maintained at 6-12 cm H2O.Intraoperative blood loss and blood transfusion were recorded.Results Compared with NCLCVP1-3 groups,intraoperative blood loss was significantly decreased in CLCVP1-3 groups (P ＜ 0.05).Compared with NCLCVP3 group,the amount of blood transfusion was significantly decreased,the constituent ratio of intraoperative blood loss ＜ 200 ml was increased,and the constituent ratio of intraoperative blood loss ＞ 1000 ml was decreased in group CLCVP3 (P ＜ 0.05).Conclusion CLCVP can decrease the intraoperative blood loss and blood transfusion in patients undergoing irregular hepatectomy.

Compared to control group, mRNA levels of MBP, PLP, MAG all significantly decreased on day 0,day 7 after operation(P all ＜ 0. 05), and these levels slightly increased on day 14 after operation (P ＞ 0. 05). Conclusion Oligl transcription factor may be essential in the remyelination and repair of myelin in PVL.

OBJECTIVETo compare the efficacy between eccentric fixation and internal fixation for treatment of intertrochanteric fractures of femur,to provide a theoretical basis for the selection of the treatment method of the intertrochanteric fractures of femur.

METHODSFrom February 2007 to January 2010,82 patients with femoral intertrochanteric fracture were treated by internal fixation including 39 cases of eccentric fixation involving 23 males and 6 females, aged from 41 to 81 years old with an average of (62.68±10.69), using the DHS or proximal femoral locking plate; 43 cases of intramedullary fixation involving 15 males, 28 females,aged from 43 to 78 years old with an average of (62.60±8.37),using PFN or PFNA fixed. The surgical incision length, operative time, blood loss and postoperative Harris score between two groups were compared.

RESULTSThe wound of two groups were primary healing without operative complications. All cases received follow-up for an average time of 18.3 months (12 to 28 months). The incision length, operative time and blood loss had a statistically significant difference between two groups (P<0.05). Harris scores of hip joint function at 1 month after operation had statistically significant difference between two groups (P<0.05), and Harris scores at 12 months after operation had no statistical significance difference between two groups. The rate of excellent and good was 89.7% in eccentric fixation group and 90.7% in intramedullary fixation group,the difference was not statistically significant (t=0.0613, P>0.05). In eccentric fixation group, there was 1 case of fracture nonunion with DHS loose and ensuing hip varus deformity. In intramedullary nail fixation group, there was no anti-rotation out,distal intramedullary nail of femoral refracture occurred in 1 case.

CONCLUSIONTwo treatment methods for the treatment of femoral fractures had a good therapeutic effect,but the intramedullary fixation had shorter operative time and less blood loss than the eccentric fixation,it prior to apply to osteoporosis and unstable femoral intertrochanteric fractures.
