As one of the important founders of GAO's acupuncture academic school in YanZhao area, Professor GAO Yuchun 's experience of acupuncture for headache is summarized in this paper. In the opinion of Professor GAO, the treatment of headache should focus on eliminating evil and relieving pain, and the syndrome differentiation should be based on meridian differentiation, especially on three yang meridians of foot as well as liver meridian and kidney meridian. In the acupoint prescription, attention should be placed on strengthening the spleen and stomach. The midnight-midday ebb flow acupuncture is advocated. The combination between acupuncture order and movement of qi is emphasized. In the manipulation, the role of pressing hand, the stimulation during reinforcing and reducing methods, and needle-retention time are important. The breathing reinforcing and reducing method of acupuncture are also advocated.

Objective: To observe the difference of the effect of low-frequency electroacupuncture (EA) on blood lipids between male and female patients with simple obesity due to damp induced by spleen deficiency. Methods: Eighty patients with simple obesity were recruited, including 37 males and 43 females, to receive low-frequency EA by selecting Yinlingquan (SP 10), Sanyinjiao (SP 6), Zusanli (ST 36), Fenglong (ST 40), Quchi (LI 11), Tianshu (ST 25), Zhongwan (CV 12), Shuifen (CV 9), Qihai (CV 6) and Guanyuan (CV 4), with needles retained for 30 min. The treatment was given once a day, 10 sessions as a treatment course, for 2 courses in total. The contents of body fat percentage (F%), total cholesterol (TC), triglyceride (TG), high-density lipoprotein (HDL), low-density lipoprotein (LDL), blood glucose (Glu) and adiponectin (ADPN) in serum were observed to see the changes, and the two groups were compared and analyzed. Results: After the treatment, F%, and serum contents of TC, TG, LDL, Glu and ADPN dropped significantly in the two groups (P<0.05 or P<0.01) and the serum content of HDL increased significantly in male group (P<0.05). The decrease of F% in female group was more significant than that in male group (P<0.01); the decrease of ADPN in male group was more significant than that in female group (P<0.05). Conclusion: EA can regulate the disordered blood lipids in male and female patients with simple obesity, with certain differences between genders. The decrease of subcutaneous fat content is more significant in females than that in males, while the decrease of ADPN is more significant in males.

BACKGROUNDTo evaluate the influence ultrasonic processing on the aggregation of PrP(Sc) in the brain extracts prepared from the scrapie-infected hamsters, and to seek for the way to prepare lower molecular PrP(Sc) polymer.

METHODSThe extracts of infected brains were prepared with a lysis solution, and treated with ultrasonics at various conditions during the different phases. The distribution and aggregation state of PrP(Sc) were analyzed by proteinase K treated. Western blot, and afterwards, quantitatively calculated with a commercially supplied software Image Totaltech.

RESULTSThe amount of PrP(Sc) in the supernatant of brain homogenates was 1.29-to 1.58-fold increased with appropriate sonication (15 s for 30 times). At the same conditions of ultrasound, the PrP amount in the supernatant prepared from the scrapie-infected hamster brain was significantly increased, whereas that prepared from healthy animal used as normal control showed little change. Comparative analyses of PrP(Sc) pellets prepared by high-speed centrifugation revealed that about 90% PrP(Sc) released into supernatant after ultrasound processing.

CONCLUSIONAppropriate sonication of homogenate of scrapie-infected brain increases the extracted amount of PrP(Sc), being favorable to laboratory diagnosis. Larger molecular PrP(Sc) aggregates can be crashed by ultrasonic processing, engendering lower molecular PrP(Sc) polymers.

Objective: To investigate the effect of moxibustion at Shenque (CV 8) on fatigue in rats with chronic exercise-induced exhaustion. Methods: Thirty male Sprague-Dawley (SD) rats were randomly divided into a blank group, a model group and a moxibustion group, 10 rats in each group. Except rats in the blank group, the remaining rats were subjected to create long-term exhaustion models by repeated swimming. After successful modeling, rats in the moxibustion group received mild moxibustion at Shenque (CV 8) for 15 min, once every other day with a total of 10 times. Rats in the model group and the blank group did not receive moxibustion. At the end of the treatment, the exhausted times, and the body weight of rats before and after the experiment were compared among groups. The levels of blood malondialdehyde (MDA) and urea nitrogen (BUN), as well as the activities of aspartate transarninase (AST), alanine aminotransferase (ALT) and lactate dehydrogenase (LDH) were also measured by the automatic biochemical analyzer, 24 h after the exhausting excise. Results: The 10th swimming time was significantly longer in the moxibustion group than that in the model group (P<0.01). The increase rate of the body weight was lower in the rats of the moxibustion group than that in the model group before the 7th and the 10th exhausting excise (P<0.05, P<0.01). The levels of serum MDA and BUN, as well as the activities of AST, ALT and LDH in the model group were higher than those in the blank group (all P<0.01). The levels of serum MDA and BUN, as well as the activities of AST, ALT and LDH in the moxibustion group were lower than those in the model group (P<0.01). Conclusion: Moxibustion at Shenque (CV 8) can decrease the serum levels of MDA and BUN, as well as activities of AST, ALT and LDH in the long-term fatigue rats, thus to improve the symptoms of fatigue.

Objective:To investigate the effect of moxibustion at Shenque (CV 8) on free radical metabolism in rat's hippocampus after different degrees of exhaustive exercise.Methods:A total of 72 male Sprague-Dawley (SD) rats were randomly divided into a normal group (n=8),a model group (n=32) and a moxibustion group (n=32).According to the times of modeling or treatment,the model group was further randomly divided into different subgroups of a 1-time model subgroup,a 4-time model subgroup,a 7-time model subgroup and a 10-time model subgroup (n=8);the moxibustion group was also further randomly divided into different subgroups of a 1-time moxibustion subgroup,a 4-time moxibustion subgroup,a 7-time moxibustion subgroup and a 10-time moxibustion subgroup (n=8).Rats in both model and moxibustion subgroups were subjected to establishing the swimming exhaustive model.Rats in each moxibustion subgroup received mild moxibustion at Shenque (CV 8) for 15 min immediately after modeling,once every other day.The concentration of malic dialdehyde (MDA),as well as the activities of superoxide dismutase (SOD),glutathione peroxidase (GSH-Px) and total antioxidant capacity (T-AOC) in rat's hippocampus in each group were detected 24 h after the exhaustive exercise.Results:Compared with the 1-time model subgroup,the exhaustive swimming time of rats was significantly prolonged in the 4-time model subgroup (P＜0.01),while it was significantly shortened in the 7-time and 10-time model subgroups (both P＜0.01).Compared with the matched model subgroup,the exhaustive swimming time of rats in the 7-time and 10-time moxibustion subgroups was significantly prolonged (both P＜0.01).Compared with the normal group,the MDA concentration was increased significantly (P＜0.01),and the activities stress response of SOD and T-AOC were increased in the 1-time model subgroup (both P＜0.05);the MDA concentration was increased (all P＜0.01),and the activities of SOD,GSH-Px and T-AOC were decreased differently (P＜0.05 or P＜0.01) in the 4-time,7-time and 10-time model subgroups.Compared with the matched model subgroup,the concentration of MDA was significantly reduced (P＜0.05 or P＜0.01),and the activities of SOD,GSH-Px and T-AOC were significantly increased in the 4-time,7-time and 10-time moxibustion subgroups (all P＜0.01).Conclusion:Moxibustion at Shenque (CV 8) can improve the fatigue status of the body after long-term exhaustive exercise by regulating free radical metabolism in rat's hippocampus.To some extent,this provides an experimental basis for moxibustion at Shenque (CV 8) against exercise-induced fatigue.

Glycyrrhetinic acid is a major active ingredient in licorice, a famous traditional Chinese medicine. Many studies on its anti-tumor activities and low toxicity to normal cells have attracted a great deal of attention. Reports indicated that glycyrrhetinic acid inhibited the growth of tumor cells through inducing apoptosis, differentiation and the block of cell cycle, suppressing tumor metastasis, reversing the multidrug resistance. Glycyrrhetinic acid also presented synergistic effects combined with chemotherapeutics and could inhibit the carcinogenesis induced by carcinogen. With further studies on mechanism of anticancer actions, glycyrrhetinic acid is being expected to have a good prospect of development and application for cancer therapy.

Objective To study the correlation of fecal calprotectin and lactoferrin with intestinal mucosa lesions in Crohn′s disease (CD). Methods Eighty-eight cases of diagnosed CD patients were selected as study group and 35 irritable bowel syndrome (IBS) patients were as controls. Fecal samples of CD patients were collected in one week before colonoscopy examination and of IBS patients were collected of CD patients, CD activity index (CDAI) was calculated at same visit, and CD endoscopic index (CDEI) was calculated in the subsequent endoscopic examination. The level of fecal calprotectin and lactoferrin were tested by ELISA method. Results The median levels of facal calprotectin and lactoferrin in CD patients were 277.16 mg/kg (from 96.85 to 693.57 mg/kg) and 59.68 mg/kg (from 10.75 to 100.58 mg/kg) respectively, which were significantly higher than those of IBS patients (7.6mg/kg, from 5.54 to 32.3 mg/kg and 0.65 mg/kg from 0.23 to 4.34 mg/kg), (Z=-8.301 and -7.986, respectively both P =0.000). There were no significant difference of calprotectin and lactoferrin level between CD patients with colon pathological changes and without colon pathological changes (Z=-0.424 and -0.699,P=0.672 and 0.485, respectively). There was no significant difference of calprotectin and lacoferrin level between remission and active periods in CD patients (Z=-1.491 and -1.075, P=0.136 and 0.283, respectively). The median values of calprotectin and lactoferrin of patients in moderate and severe active period judged under endoscopy were 663.11 mg/kg (from 263.45 to 2015.63 mg/kg) and 105.64 mg/kg (from 56.52 to 187.44) mg/kg respectively, in mild active period were 344.54 mg/kg (from 132.03 to 722.67 mg/kg) and 86.68 mg/kg (from 21.07 to 100.55 mg/kg) accordingly, and in remission period were 133.94 mg/kg (from 60.54 to 583.33 mg/kg) and 45.31 mg/kg (from 7.59 to 48.31 mg/kg, respectively). Both calprotectin and lactoferrin levels were significantly higher in active period than in remission period (χ2=10.63 and 8.18, while, P=0.005 and 0.017, respectively). Conclusions The level of fecal calprotectin and lactoferrin can reflect the pathological changes and severity of the intestinal mucosa.

AIMTo research the spontaneous firing activities during different-frequency stimulation of subthalamic nucleus and microelectrophoresis GABA, Glu and their antagons respectively, approaching the mechanism of DBS in the treatment of Parkinson's disease further.

METHODSUsing extracellular recording to investigate the effect of different-frequency stimulation of STN and microelectrophoresis several drugs on the spontaneous firing activities of the SNr neurons.

RESULTSFor STN stimulation at low frequency, there was no difference on the spontaneous firing activities of SNr neurons between pro-stimulation and meta-stimulation (P > 0.05). With the increasing of stimulation frequency, most of the SNr neurons were inhibited. While during the STN stimulation frequency at high-frequency, the firing rates of inhibited SNr neurons were changed (P < 0.05). Glu had catatonic excitement effect on the SNr neurons, whereas GABA had tonic inhibition effect. 80% of SNr neurons which were inhibited by STN-HFS were not inhibited by STN-HFS on the basis of excitatory effect of BIC.

CONCLUSIONTo treat the motor symptoms of PD, when SIN is selected as the target nucleus, the electrical stimulation with high-frequency should be chosen. It is possible that SIN-HFS modulate the activity of SNr by inhibitory effect of GABA predominantly.
