OBJECTIVETo evaluate the effect mechanism of warm acupuncture combined with auricular point sticking therapy and its efficacy on insomnia by monitoring the level of brain neurotransmitters in the insomnia patients.

METHODSOne hundred and thirty patients with insomnia were randomized into an observation group and a control group, 65 cases in each one. In the observation group, based on the treating principle of warming yang and benefiting qi, acupuncture was applied to Xinshu (BL 15), Pishu (BL 20), Shenshu (BL 23), Yaoyangguan (GV 3), Baihui (GV 20), Neiguan (PC 6) and Shenmen (HT 7). Warm acupuncture was supplemented at Xinshu (BL 15), Pishu (BL 20), Shenshu (BL 23) and Yaoyangguan (GV 3). The treatment was given once every day. In the control group, estazolam tablets, 0. 5 to 1 mg were prescribed for oral administration, 30 min before sleep at night. The treatment of 14 days was taken as one session and 2 sessions were required in the two groups. The encephal of luctuograph technology was used to observe the sleep quality and brain neurotransmitters before and after treatment in the two groups and the efficacy was compared between the two groups.

RESULTSThe total effective rate was 83.1% (54/65) in the observation group and 87.7% (57/65) in the control group. The efficacy was similar between the two groups (P > 0.05). In the observation group, after treatment, 5-HT and GABA/Glu were all increased compared with those before treatment (P < 0.05, P < 0.01) and norepinephrine (NE) was reduced compared with that before treatment (P < 0.05). The level of each index did not change significantly before and after treatment in the control group (all P > 0.05). The regulations of 5-HT, GABA/Glu in the observation group were superior to those in the control group (all P < 0.05).

CONCLUSIONThe combined therapy of warm acupuncture and auricular point sticking method for warming yang and benefiting qi effectively improves brain neurotransmitters and essentially improves sleep quality of the patients with insomnia differentiated as yang deficiency pattern.

Objective:To explore the regulatory effect of glutathione S-transferase P1(GSTP1) on the radiosensitivity of mouse Lewis lung cancer (LLC) cells.Methods:GSTP1-shRNA lentivirus and negative control lentivirus were used to respectively infect the LLC cells, and stable transgenic strains were selected. Real-time PCR and Western blot were conducted to quantitatively measure the expression levels of GSTP1 mRNA and protein in the LLC cells to verify the knockdown effect. The cell counting kit-8(CCK-8) assay was used to detect cell viability after irradiation. The colony formation assay was utilized to assess the cell proliferation ability after irradiation. Flow cytometry was performed to assess the level of cell apoptosis after irradiation. The tumor-bearing mice were established and irradiated to detect the changes in the tumor volume after irradiation. TUNEL staining was employed to detect the level of tumor apoptosis after irradiation. Immunofluorescence was used to detect the number of CD 4+ CD 8+ T cells in the tumor after irradiation. Results:Real-time PCR and Western blot showed that after shRNA lentivirus interference, the expression levels of GSTP1 mRNA and protein were significantly down-regulated. Down-regulation of GSTP1 reduced cell viability and proliferation, and increased the rate of cell apoptosis after irradiation. The tumor volume of the tumor-bearing mice after irradiation in the GSTP1 knockdown group was significantly smaller than that in the NC group, whereas the tumor apoptosis rate was significantly higher and the number of infiltrating CD 4+ CD 8+ T cells in the tumor was remarkably higher compared with those in the control group. Conclusion:Knockdown of GSTP1 can significantly increase the radiosensitivity of LLC cells and enhance the infiltration of lymphocytes in tumor tissues.

OBJECTIVE: To investigate the relation between injury time and the expression of cytochrome c oxidase subunit VIc (COX6C) mRNA in skeletal muscle of rat after contusion. METHODS: A total of fifty-four SD rats were divided into the control group and the contusion groups (0.5, 1, 6, 12, 18, 24, 30, and 36 h after contusion), randomly. The contusion model was established by free fall drop of gravity hammer. At corresponding time point after contusion, the regular histology was examined and expression level of COX6C mRNA was tested by real-time PCR after extraction of total RNA from the tissues. RESULTS: The main pathological features of 6 h after injury included edema and hemorrhage in myocytes with no inflammatory cells found. After 6 hours, the findings included myocyte degeneration and necrosis, inflammatory cells infiltration, and fibrous connective tissue proliferation in the contused zone. The expression level of COX6C mRNA was higher than that of the control group within 6 h after contusion. The expression level was lower than that of the control group from 6-36 h after contusion. CONCLUSION The level of COX6C mRNA expresses in a regular way after contusion. It may be useful for estimating wound age in combination with the results of pathological features.

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.

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.

OBJECTIVE: In order to understand which kind of function genes play an important role for estimating wound age, the variation of difference genes' mRNA expression were compared after injury. METHODS: The mRNA expression levels of seven candidate genes (ICAM-1, NF-κB, MX2, MT1, MT2, sTnI, and Cox6c) were analyzed in contused rat skeletal muscle at different time points using real-time fluorescent quantitative PCR (RT-qPCR). The raw Ct values were normalized relative to that of RPL32 mRNA, and converted to standard Ct values. At each time point after injury, the standard deviations (SD) of the standard Ct values were calculated by SPSS. RESULTS: The expression trends of the seven genes were all found to be related to wound age, but there were lower variation coefficients and greater reliability of s TnI and Cox6c when compared with other genes. CONCLUSION The genes encoding structural proteins or proteins that perform basic functions can be suitable for wound age estimation.

Rheum franzenbachii (called Tudahuang in local) has some similarities with R. palmatum (rhubarb) collected by "China Pharmacopoeia" and is often used as a substitute of rhubarb. Can Tudahuang simply replace rhubarb in the application or whether is there difference between Tudahuang and rhubarb, and what is the difference it is important to verify the difference and understand its proper application in the field of clinical practice. In this paper, we discussed the differences of the two herbs from the views of chemistry, efficacy and toxicity based on the author's previous research work as well as literatures, by using the major role of the rhubarb "diarrhea" as the basic point. The analysis result showed that the role of diarrhea Tudahuang was much weaker than that of rhubarb. The reason lies in the difference between the contents of combined anthraquinones component. While acute toxicity in mice of Tudahuang is stronger than that of rhubarb. Thus, Tudahuang should not simply replace rhubarb in practice.
