[Effect of Biantie pretreatment on serum level of PHD2/HIF-1α and brain tissue damage in rats during acute hypobaric hypoxia exposure].

OBJECTIVE: To observe the effect of Biantie (bian stone plaste) pretreatment on serum level of prolyl hydroxylase domain 2 (PHD2) and hypoxia-inducible factor-1α (HIF-1α) in rats with acute hypobaric hypoxia induced-brain injury, and to explore the possible mechanism of Biantie on preventing brain injury at high altitude. METHODS: Forty-five male SD rats were randomly divided into a blank group, a model group, a Biantie group, a medication group and a Biantie+inhibitor group, 9 rats in each group. The rats in the Biantie group the and the Biantie+inhibitor group were pretreated with Biantie at "Taiyuan" (LU 9), "Neiguan" (PC 6) and "Renying" (ST 9), 2 h each time, once a day; the rats in the medication group were treated with intragastric administration of rhodiola capsule solution (280 mg/kg) for 14 d; the rats in the Biantie+inhibitor group were intraperitoneally injected with the PHD inhibitor dimethyloxalyl glycine (DMOG) at a dose of 40 mg/kg 24 h before the establishment of the model. After the intervention, except for the blank group, the rats in the remaining 4 groups were placed in the oxygen chamber to simulate a high-altitude environment to establish the acute hypobaric hypoxia brain injury model. The arterial blood-gas analysis indexes [blood oxygen saturation (SaO2), lactic acid (Lac), blood sodium (Na+), blood potassium (K+)] and brain water content were detected in each group; the histomorphology of cerebral cortex was observed by HE staining; the serum levels of PHD2 and HIF-1α as well as vascular endothelial growth factor (VEGF) were detected by ELISA; the VEGF protein expression in brain tissue was detected by Western blot; the VEGF mRNA expression in brain tissue was detected by real-time fluorescent quantitative PCR. RESULTS: Compared with the blank group, the levels of SaO2 and Na+ in the model group were decreased (P<0.05), while the levels of Lac and K+ as well as the water content of brain tissue were increased (P<0.05). Compared with the model group, the level of SaO2 in the Biantie group and the medication group was increased (P<0.05), while the levels of Lac, K+ and the water content of brain tissue were decreased (P<0.05); the level of Na+ in the Biantie group was increased (P<0.05). Compared with the Biantie group, the level of SaO2 in the Biantie+inhibitor group was decreased (P<0.05), and the level of Lac and the water content of brain tissue were increased (P<0.05). In the model group, the cortical tissue cells were loose and disordered, the cortical blood vessels were dilated, and the cells were obviously swollen; the anoxic injury in the Biantie group and the medication group was lighter, and the anoxic injury in the Biantie+inhibitor group was more obvious than that in the Biantie group. Compared with the blank group, the serum PHD2 content in the model group was decreased and the HIF-1α content was increased (P<0.05), and the content of VEGF in serum and VEGF protein and mRNA expressions in brain were increased (P<0.05). Compared with the model group, the content of PHD2 in serum in the Biantie group and the medication group was increased (P<0.05), and the level of HIF-1α was decreased (P<0.05), and the content of VEGF in serum as well as VEGF protein and mRNA expressions in brain were decreased (P<0.05). Compared with the Biantie group, the serum PHD2 content in the Biantie+inhibitor group was decreased and HIF-1α level were increased (P<0.05), and the content of VEGF in serum as well as VEGF mRNA expression in brain were increased (P<0.05). CONCLUSION: Biantie at "Taiyuan" (LU 9), "Neiguan" (PC 6) and "Renying" (ST 9) could regulate serum PHD2/HIF-1α to down-regulate VEGF expression, reduce brain edema and enhance anti-hypoxia ability, so as to achieve the purpose of preventing brain injury at high altitude.

Effects on the tumor specific growth factor and tumor necrosis factor α in rats' precancerous lesion of primary hepatocellular carcinoma by direct moxibustion at Ganshu (BL 18) acupoint.

OBJECTIVE: To investigate the effect of direct moxibustion at Ganshu (BL18) on the serum concentrations of tumor specific growth factor (TSGF) and tumor necrosis factor α (TNF-α) in a rat model with precancerous lesion of primary hepatocellular carcinoma (HCC), so as to explore the mechanism of moxibustion underlying improvement of HCC. METHODS: Sixty male Wistar rats were randomly divided into control group (n=10), model group (n=20), prevention group 1 (n=15) and prevention group 2 (n=15). The normal rats were injected with physiological saline as blank control. At the same time, the rats of other three groups were injected with diethylnitrosamine to establish the HCC model. Direct moxibustion with grain-sized moxa was applied to bilateral Ganshu acupoint of the rats in the prevention group 1 (1 treatment course, 20 days) and prevention group 2 (2 treatment courses, 40 days), 5 doses for each acupoint, 0.5 mg/dose, once every other day. At each time point (before model establishment, the end of 1st course prevention, the end of 2nd course prevention and the end of model establishment), serum levels of TSGF and TNF-α were detected using enzyme-linked immunosorbent assay. RESULTS: Compared with the control group, there was a remarkably increase of serum TSGF and TNF-α contents in the model group at the end of the experiment (P<0.05). At the end of the 1st course of direct moxibustion, the contents of serum TSGF and TNF-α of rats in the prevention group 1 were significantly increased compared with that of the model group (P<0.05). At the end of the 2nd course of direct moxibustion, serum TSGF and TNF-α levels of rats in the model group were higher than the normal group with significantly difference (P<0.05), and the levels of TSGF and TNF-α in the prevention group 2 were significantly reduced in comparison with the model group (P<0.05). CONCLUSION: It was possible that direct moxibustion could inhibit precancerous lesion and postpone hepatocarcinogenesis, and the therapeutic effect of two courses were better than one course.

[Effects of Direct Moxibustion of "Ganshu"(BL 18) on the Contents of T cells in Peripheral Blood in Rats with Precancerous Lesion of Primary Hepatocellular Carcinoma].

OBJECTIVE: To observe the effect of moxibustion stimulation of "Ganshu"(BL 18) region on contents of T cells in the peripheral blood in rats with Diethylnitrosamine (DEN)-induced hepatocellular carcinoma (HCC), so as to explore its effective in improving immunoregulatory function. METHODS: Seventy male Wistar rats were randomly divided into control group (n=10), model group(n=15), direct moxibustion-15 s group(n=15), direct moxibustion-30 s group (n=15) and ginger-separated moxibustion group(n=15). The primary HCC precancerous lesion model was established by intraperitoneal injection of DEN (50 mg/kg), once every 3 days for 10 weeks. Moxibustion was applied to bilateral "Ganshu"(BL 18) for about 15 min (3 moxa-cones), or 30 min (six moxa-cones), with or without ginger-slice separation, once every other day for 10 consecutive weeks. The contents of T cells of CD 3+, CD 4+, CD 8+ and CD 4+/CD 8+ ratio in the peripheral blood were detected with Flow Cytometey(FCM), pathological changes of liver were observed by light microscope after hematoxylin-eosin(HE) stain. RESULTS: Compared to the control group, the contents of blood CD 3+ and CD 4+ T cells and ratio of CD 4+/CD 8+ were significantly down-regulated, while that of CD 8+T cells was obviously increased in the model group(P<0.05,P<0.01). After moxibustion intervention, the decreased CD 3+ and CD 4+T cells and CD 4+/CD 8+ levels and the increased CD 8+T cell contents were reversed in all the 3 moxibustion groups (P<0.05, P<0.01), except CD 3+ in the ginger-separated moxibustion group (P>0.05). There were no significant differences among the three moxibustion groups in the CD 3+, CD 4+, CD 8+ and CD 4+/CD 8+ levels (P>0.05). In addition, the pathological changes of liver tissue as central vein deviation or absence, disordered arrangement of hepatic cords, narrowing of the hepatic sinusoid, hyperplasia of collagen fibers, formation of tuberosis, unevenness of liver cells with nuclear anachromasis and higher heteromorphism, and macronucleus oncocytes in primary HCC rats were not observed or milder after moxibustion intervention. CONCLUSIONS: Direct moxibustion and ginger-separated moxibustion can improve pathological changes of hepatic cells in rats with HCC, which may be associated with its actions in raising blood CD 3+ and CD 4+ T cell contents and reducing CD 8+ T levels to improve immune function.

[Effects of moxibustion at "Ganshu" (BL 18) on serum alpha-fatoprotein and liver livin levels in rats with precancerous lesion of primary hepatocellular carcinoma].

OBJECTIVE: To observe the effect of moxibustion at "Ganshu" (BL18) on levels of Livin (a novel member of the inhibitors of apoptosis family and plays crucial roles in apoptosis, cell proliferation, and cell cycle control) in the liver tissue in rats with precancerous lesion of primary hepatocellular carcinoma (HCC), so as to explore its mechanism underlying improvement of HCC. METHODS: Sixty male Wistar rats were randomly divided into control group (n = 10), model group (n = 20), moxibustion-20 d group (n = 15) and moxibustion-40 d group (n = 15). HCC model was established by intraperitoneal injection of diethylnitrosamine (DEN, 50 mg/kg), once every 3 days for 12 weeks. Moxibustion was applied to bilateral "Ganshu" (BL 18), once every other day for 10 times (moxibustion-20 d group) and 20 times (moxibustion-40 d group), respectively. Serum alpha-fetoprotein (AFP) content was detected with ELISA and Livin immunoactivity of the liver tissue detected using immunohistochemistry. RESULTS: After modeling, serum AFP content and liver Livin immunoactivity of the model group were significantly increased in comparison with the control group (P < 0.01). After moxibustion treatment, serum AFP content in the moxibustion-20 d group and liver Livin immunoactivity in both moxibustion-20 d and moxibustion-40 d groups were remarkably down-regulated in comparison with the model group (P < 0.05). No significant differences were found between the moxibustion-40 d group and the model group in serum AFP content (P > 0.05). CONCLUSION: Moxibustion can down-regulate liver Livin protein expression, which probably has a role in promoting hepatocellular apoptosis to inhibit precancerous lesion and to postpone hepatocarcinogenesis.

[Cross-sectional survey of characteristics of reaction point Jingtong in balance acupuncture].

OBJECTIVE: To explore the performance patterns of reaction point Jingtong in balance acupuncture through multi-center and big-sample clinical investigation. Methods The Jingtong points of balance acupuncture on healthy side and affected side were observed among 230 cases of cervical spondylosis and scores of self-discomfort in reaction point, color of skin, changes of skin, morphology of subcutaneous tissue and abnormal pressing pain were recorded. The software SPSS 15.0 was applied to statistically analyze the recorded scores. RESULTS: Among 230 cases, the reaction point appeared in 226 cases, accounting for 98. 3%. Among the 226 cases who had reaction point, the total score of symptom and sign was (1.08+/-1.09) on the healthy side and (0. 84+/-1. 36) on the affected side, which had statistical significance (P<0. 01); score of self-discomfort in reaction point was (0. 76 +/-0. 83) on the healthy side and (0. 40+/-0.80) on the affected side, which had statistical significance (P<0.01); the score of skin color was (0.10+/-0.36) on the healthy side and (0. 03+/- 0. 19) on the affected side, which had statistical significance (P<0. 05); the score of abnormal pressing pain was (2. 47+/-2. 46) on the healthy side and (1. 39+/-2. 37) on the affected side, which had statistical significance (P<0. 01). CONCLUSION: The total score of symptom and sign of reaction point Jingtong on the healthy side is higher than that on the affected side, indicating positive reaction of Jingtong on the healthy side has specificity for cervical spondylosis. When patient has cervical spondylosis on either side of neck, the other side will have anomaly in Jingtong.

In the control group, the chest circumference, the SP and DP had no significant improvement (P>0.05), while the heart rate was significantly increased and the weight was significantly decreased (P<0.01). (2) The test group achieved significant positive changes in the performance status, state of mind and fatigue index (P<0.01 or P<0.05), while the control group only achieved a significant positive change in performance status (P<0.01), and a negative significant decrease in the autonomic nerve function (P<0.05). CONCLUSION: Junior school students would get physiological and psychological benefit from practicing CTHE, and which is suitable for them to practice.

[Comparative study on curative effects of stroke treated with acupuncture by NIRS].

OBJECTIVE: To compare the intracephalic imaging differences of stroke treated with combined therapy of scalp and body acupuncture and body acupuncture only, in order to apply the image basis for the differences of clinical curative effects. METHODS: Twenty cases of stroke were randomized into a body acupuncture group (group A) and a scalp and body acupuncture group (group B), ten cases in each group respectively. In group A, body acupuncture was applied simply, and different acupoints were selected according to the symptoms: Shousanli (LI 10), Jianliao (TE 14), Huantiao (GB 30) and Jiaji (EX-B 2) etc. were selected for hemiplegia, Fengchi (GB 20), Xiaguan (ST 7) and Quanliao (SI 18) etc. were for facial paralysis, Fengfu (GV 16) and Lianquan (CV 23) etc. were for aphasia. In group B, combined therapy were applied, the body acupoints selection was same as above; for scalp acupoints, corresponding motor area, sensory area and foot motor sensory area were selected. Instant changes of local cerebral blood flow before and after treatment were examined and evaluated by NIRS and the curative effects of both groups were evaluated. RESULTS: The total therapeutic effective rate was 90.0% (9/10) and the basically cured rate was 30.0% (3/10) in group A; and 100.0% (10/10) and 50.0% (5/10) respectively in group B, indicating that the clinical curative effect in group B was superior to that in group A at 20, 30 min of acupuncture treatment (P < 0.05). Both imaging results showed that blood flows of prefrontal cortex in both groups were increased with varying degrees after treatment (P < 0.05, P < 0.01); the cerebral blood flow in group B was much more improved than that in group A at 20, 30 min of acupuncture treatment (all P < 0.05). CONCLUSION: Acupuncture can significantly increase blood flow and oxygen saturation in brain cortex, and the effect with combined therapy of scalp and body acupuncture is superior to that with body acupuncture.
