of collagen fibers in skeletal muscle, which leads to the fibrosis of skeletal muscle. Acupuncture can inhibit skeletal muscle fibrosis via down-regulating TGF-β1/ERK/CTGF signaling pathway.

To study the effect of blood-letting puncture at "Well-points" of the twelve meridians on hippocampal mitophagy of hypobaric hypoxia-induced brain injury (HHIBI) rats, so as to explore its biological mechanisms underlying improvement of high altitude hypoxia-induced brain injury.

Male SD rats were randomly divided into normal control group （

=9）， and model and blood-letting groups which were further divided into 6, 12, 24, 48 and 72 h subgroups (

=9 in each subgroup). The HHIBI model was established by putting the rats into a hypobaric hypoxia chamber (equivalent to 5 000 m above sea level).The blood-letting groups were given blood-letting therapy at "Shaoshang"(LU11), "Shangyang"(LI1), "Zhongchong"(PC9), "Guanchong"(SJ1), "Shaochong"(HT9), "Shaoze"(SI9), once a day for 7 days. H.E. staining was used to observe the histopatholo-gical changes of hippocampus tissue. Serum hypoxia inducible factor(HIF)-1α and vascular endothelial growth factor(VEGF) contents were assayed using ELISA, and the expression levEGF contents and hippocampal Beclin-1 and LC3-Ⅱ (mitophagy related proteins) expressions in HHIBI rats, which may contribute to its effect in reducing hypoxic brain injury.

Blood-letting of "Well-points" can up-regulate serum HIF-1α and VEGF contents and hippocampal Beclin-1 and LC3-Ⅱ (mitophagy related proteins) expressions in HHIBI rats, which may contribute to its effect in reducing hypoxic brain injury.

To observe the effect of electroacupuncture (EA) on Cathepsin-B in the synovium of the knee joint of acute gouty arthritis(AGA) rats, so as to explore the mechanism of EA in the treatment of AGA.

A total of 60 male Wistar rats were randomly divided into normal control,model, medication and EA groups, with 15 rats in each group. Rat model of AGA was established by injection of 0.2 mL sodium urate crystal suspension into the left knee joint cavity. The rats in the medication group were treated with colchicine by gavage(0.3 mg·kg

·d

), and the rats in the EA group were treated with EA at the left "Sanyinjiao" (SP6) and "Zusanli"(ST36) for 10 min each time, once a day for a week. The Coderre gait grading standard was used to score the gait of rats. The pathological morphology of synovial tissue of the left knee joint was observed by H.E. staining. The expression levels of Cathepsin-B protein and Nod-like receptor pyrin domain 3(NLRP3), apoptosis-associated speck-like protein containing CARD (ASC),Caspase-1,nhibit the activation of NLRP3 inflammasome by reducing the activity of Cathepsin-B in the synovium of the knee joint, so as to treat AGA.

To observe the effect of electroacupuncture (EA) on the hemorheology and hepatic microcirculation in mice with chronic alcoholic liver injury (cALI), so as to explore the microcirculation mechanism of EA underlying regulating liver function in cALI mice.

Forty Kunming mice were randomly assigned to control, model, acupoint EA and non-acupoint EA groups, with 10 mice in each group. The cALI model was established by gavage with 50% ethanol (15 mL/kg，2 times per day with 8 hours' interval) for 28 d. Mice in the acupoint EA group received EA at bilateral "Zusanli" (ST36) and "Ganshu"(GB11) for 20 min, once daily for 14 d. And mice in the non-acupoint EA group received EA the spot about 1 cm lateral to GB11 and 0.5 cm lateral to ST36 respectively for 20 min, once daily for 14 d. The hepatic blood perfusion (HBP) of mice was detected by laser speckle perfusion imaging. The index of hemorheology, serum markers of liver function and hepatic histology in mice were observed by automatic blood rheometer, automatic bue was reduced, and the focal necrosis was reduced. The plasma viscosity, erythrocyte sedimentation rate were significantly decreased (

<0.05), and the red blood cell deformation index was significantly increased in the non-acupoint EA group relevant to the model group (

<0.05). The erythrocyte sedimentation rate and the red blood cell deformation index of the acupoint EA group was significantly lower than that of the non-acupoint EA group (

<0.05).

EA at ST36 and GB11 could improve the hemorheological disorder and the hepatic microcirculation, and inhibit the deve-lopment of liver injury in cALI mice.

To observe the effect of moxibustion and acupuncture on apoptosis in gastric mucosal cell and expression of NF-κB, Bcl-2 in chronic atrophic gastritis (CAG) rats, so as to explore its mechanisms underlying improvement of CAG.

Forty-eight male SD rats were randomly divided into normal, model, moxibustion and acupuncture groups, with 12 rats in each group. The CAG model was established by gavage of N-methyl-N'-nitro-N-nitroso-guanidine (MNNG) solution and irregular diet for 12 weeks. Moxibustion or acupuncture was applied to "Zusanli" (ST36) and "Zhongwan" (CV12) for 15 min, once daily for two weeks in the moxibustion or acupuncture group. The histopathological changes of the gastric mucosa were observed by HE staining. The apoptosis index of gastric mucosa was measured by TUNEL method. The gene expression levels of NF-κB and Bcl-2 were detected by real-time PCR.

After modeling, the color of gastric mucosa was pale and dark, with low folds and significant bleeding points. Oxythiamine chloride cost The glands in lamina propria werel-2 genes in the gastric mucosa.

To observe the effect of electroacupuncture (EA) on the expression of Pirt (a regulator of TRPV1) in the dorsal root ganglia (DRG) and transient receptor potential vanilloid 1 (TRPV1, a molecular sensor of noxious heat and capsaicin) in the colonic mucosa in rats suffering from diarrhea-predominant irritable bowel syndrome (IBS-D), so as to explore its mechanisms underlying alleviation of visceral hypersensitivity of IBS-D.

Forty SD rats (half male and half female) were randomly assigned to control, model, EA, and medication groups by lottery, with 10 rats in each group. The IBS-D model was established by chronic unpredictable mild stress (CUMS) and gavage of senna soaking fluid. Rats in the EA group received EA (2 Hz/15 Hz,0.1-1 mA) stimulation of unilateral "Tianshu"(ST25), "Zusanli" (ST36), "Sanyinjiao"(SP6) and "Taichong"(LR3) for 15 min once a day for 14 days, and rats of the medication group received intragastric administration of pinave-rium bromide (10 mL/kg, 2.7 mg/mL) once daily for 14 days. The visceral pain threshold (VPT) was measured by using abdominal wall withdrawal reflex (AWR) test.
