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.

Objective To determine Oligl transcription factor expression in periventricular tissue of day 2 newborn rat of periventricular leukomalacia (PVL) and to explore the relation with remyelination.Methods PVL newborn rat model was successfully established through bilateral common carotid artery ligation,followed by 8% oxygen exposure for 30 min. On day 0,day 7 and day 14 after operation,Oligl expression was examined through in situ hybridization, oligodendrocyte precursor cells and oligodendrocytes were detected via immunohistochemistry method and mRNA levels of MBP, PLP, MAG in control and PVL group were examined with quantitative real-time PCR. Results Oligl positive cells of control group were 115 ± 15/mm2. On day 0 and day 7 after operation,oligl positive cells were 72 ± 20/mm2and 75 ± 12/mm2 ,and there was significant difference as compared with control group (P both < 0. 05), however the oligl positive cells on day 14 after operation(146 ± 1 1/mm2) significantly increased with comparison to control group (P <0. 05). Compared to control group, GST-Ⅱ positive oligodendrocytes and O4 positive oligodendroglial progenitor cells of PVL group were significantly decreased on day 0, day 7 after operation (P both < 0. 05), and these cells both increased on day 14 after operation ,however there was no difference as compared with control group (P > 0. 05). 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.

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 evaluate the effect of hydrogen on the activation of caspase-3 in brain tissues during cerebral ischemia-reperfusion (I/R) in rats.Methods Thirty-six healthy adult male Sprague-Dawley rats,weighing 220-250 g,were divided into 3 groups (n=12 each) using a random number table:sham operation (group S),I/R group and hydrogen group (group H).Cerebral ischemia was induced by occlusion of the middle cerebral artery followed by reperfusion in I/R and H groups.In group H,hydrogen-rich saline 5 ml/kg (0.6 mmol/L) was injected intraperitoneally at 3 days before establishment of the model and immediately after the onset of reperfusion.At 24 h of reperfusion,the rats were sacrificed,and hippocampal tissues were obtained for determination of neuroapoptosis (by TUNEL),apoptotic neuron count and expression of activated caspase-3 (by Western blot).The brain tissues in the ischemic area were obtained and stained with haematoxylin and eosin for examination of the pathological changes.Results Compared with group S,the expression of activated caspase-3 was significantly up-regulated,and the apoptotic neuron count was increased in I/R and H groups (P<0.05).Compared with group I/R,the expression of activated caspase-3 was significantly down-regulated,the apoptotic neuron count was decreased (P<0.05),and the pathological changes of brain tissues were significantly reduced in group H.Conclusion The mechanism by which hydrogen inhibits neuroapoptosis during cerebral I/R is probably related to inhibited activation of caspase-3 in brain tissues of rats.
