OBJECTIVES: To investigate the effects on the motor function, cortex blood flow perfusion, microglial cells, and the contents of serum inflammatory factors, i.e. interleukin-1ß (IL-1ß), transforming growth factor-ß (TGF-ß), and interleukin-10 (IL-10) after electroacupuncture (EA) preconditioning at "Baihui" (GV20) and "Dazhui" (GV14) in the mice with ischemic stroke, so as to explore the mechanism of EA preconditioning for improving motor function after ischemic stroke. METHODS: C57BL/6 mice were randomly divided into sham-operation group, model group, and EA preconditioning group (EA group), with 15 mice in each group. A photothrombotic method was used to induce the model of unilateral ischemic stroke and motor impairment. The mice in the EA group received EA preconditioning, 20 min each time, once daily for 7 consecutive days before modeling. The motor function of mice was evaluated by the grid-walking test and cylinder test before and after modeling. Laser speckle blood flow video monitoring system was employed to assess the cerebral blood flow perfusion in the primary motor cortex of mice. The contents of IL-1ß, TGF-ß, and IL-10 in the serum were measured by ELISA, and the expressions of microglial cell and M2 subtype cell marker in the primary motor cortex were detected using immunofluorescence staining. RESULTS: After modeling, compared with the sham-operation group, the grid error rate and the dragging rate of the affected limb were increased (P<0.01)；the utilization rate of the affected limb and percentage of the blood perfusion in the affected cortex to healthy side were decreased (P<0.01)；the contents of serum IL-1ß, TGF-ß, and IL-10 were increased (P<0.01, P<0.05)；and the microglia in the primary motor cortex on the affected side showed ameboid, the fluorescence intensity of ionized calcium-binding adapter molecule 1 (IBA1) and CD206 was increased (P<0.01) in the model group. In the EA group, when compared with the model group, the grid error rate and the dragging rate of affected limb were decreased (P<0.01)；the utilization rate of affected limb and the percentage of blood perfusion were increased (P<0.05)；the content of serum IL-1ß was decreased (P<0.01), while the contents of TGF-ß and IL-10 were increased (P<0.01)；and the microglia in the primary motor cortex on the affected side got more round and were distributed more densely, the fluorescence intensity of IBA1 and CD206 was increased (P<0.01). CONCLUSIONS: Electroacupuncture preconditioning at "GV20" and "GV14" can up-regulate the expression of microglial cells, especially the M2 subtype cell marker, and increase the contents of the anti-inflammatory factors and decrease that of the pro-inflammatory factors in the serum, thereby alleviate the inflammatory reaction.

Contralateral S1 function is involved in electroacupuncture treatment-mediated recovery after focal unilateral M1 infarction.

Acupuncture at acupoints Baihui (GV20) and Dazhui (GV14) has been shown to promote functional recovery after stroke. However, the contribution of the contralateral primary sensory cortex (S1) to recovery remains unclear. In this study, unilateral local ischemic infarction of the primary motor cortex (M1) was induced by photothrombosis in a mouse model. Electroacupuncture (EA) was subsequently performed at acupoints GV20 and GV14 and neuronal activity and functional connectivity of contralateral S1 and M1 were detected using in vivo and in vitro electrophysiological recording techniques. Our results showed that blood perfusion and neuronal interaction between contralateral M1 and S1 is impaired after unilateral M1 infarction. Intrinsic neuronal excitability and activity were also disturbed, which was rescued by EA. Furthermore, the effectiveness of EA treatment was inhibited after virus-mediated neuronal ablation of the contralateral S1. We conclude that neuronal activity of the contralateral S1 is important for EA-mediated recovery after focal M1 infarction. Our study provides insight into how the S1-M1 circuit might be involved in the mechanism of EA treatment of unilateral cerebral infarction. The animal experiments were approved by the Committee for Care and Use of Research Animals of Guangzhou University of Chinese Medicine (approval No. 20200407009) April 7, 2020.

[Professor YI Wei's clinical experience in treatment of infertility of ovulation disturbance with acupuncture-moxibustion therapy].

The characteristics of syndrome differentiation and the experience of professor YI Wei were briefly introduced for the treatment of infertility of ovulation disturbance, including three aspects, named the thought of diagnosis and treatment, the therapeutic method and the acupoint prescription, as well as the clinical case report. Academically, professor YI Wei is deeply influenced by professor JIN Rui, the acupuncture master of Xin'an school and Lingnan school. Regarding the treatment of gynecological diseases, the academic thought of professor LUO Song-ping and ZHANG Yu-zhen is contributed. Professor YI attaches the importance to the syndrome differentiation based on meridian and collateral, supplemented by the syndrome differentiation of zangfu, yinyang, qi and blood, cold and heat, as well as the deficiency and excess. In clinical treatment, the acupoints are selected specially from the conception vessel, the governor vessel, the thoroughfare vessel and the belt vessel. The extra meridians are equally important as the regular ones in the treatment, especially the belt vessel. Additionally, the treatment focuses on communicating the congenital qi with the acquired one, regulating the liver and benefiting the kidney, as well as adjusting the heart, the spleen and the stomach to ease the uterus. Simultaneously, the great consideration is paid to the menstruation regulation so as to promote pregnancy.

[Clinical therapeutic effect of hyperlipidemia of turbid phlegm obstruction pattern/syndrome treated with the different Jin's three-needle therapies].

OBJECTIVE: To compare the differences in clinical effects on hyperlipidemia of turbid phlegm obstruction pattern/syndrome treated with the different Jin's three-needle therapies so as to provide a new approach and theoretic evidence for the clinical optimal scheme of acupuncture on hyperlipidemia. METHODS: A total of 90 patients were randomly divided into education group, electroacupuncture group and catgut embedding group (30 cases in each). The routine health education was given to the education group. On the base of the treatment as the education group, electroacupuncture was applied to the electroacupuncture group for 30 min each time, twice a week; and the catgut embedding was applied to the catgut embedding group at the same acupoints as the electroacupuncture group, once a week. The treatment was given consecutively for 8 weeks in each group. Before and after treatment, the obesity indices [weight, waistline, body mass index (BMI)], blood lipid indices[serum total cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C)] and insulin resistance indices [fasting blood glucose(FBG), fasting plasma insulin(FINS), homeostasis model assessment-estimated insulin resistance (HOMA-IR)] were observed in the three groups before and after treatment. RESULTS: After treatment, in the electroacupuncture group and the catgut embedding group, the results of the obesity indices, e.g. weight, waistline and BMI, the levels of blood lipid, e.g.TC, TG, LDL-C and the insulin resistance indices, e.g. FINS and HOMA-IR were all obviously decreased compared with those before treatment (P<0.05, P<0.01), and the level of HDL-C apparently increased than that before treatment (P<0.01). In the catgut embedding group, FBG was obviously decreased after treatment as compared with that before treatment (P<0.01). After treatment, the improvements in LDL-C and HDL-C in the catgut embedding group were superior to those in the electroacupuncture group (P<0.05). Regarding the obesity indices and insulin resistance indices, the differences were not statistically significant in comparison between the catgut embedding group and the electroacupuncture group (all P>0.05). The total effective rate was 90.0% in the catgut embedding group (27/30) and it was 83.3% (25/30) in the electroacupuncture group, either of them was better than 60.0% (18/30) in the education group , indicating the statistical significance (P<0.01, P<0.05). CONCLUSION: On the base of health education, either the catgut embedding therapy or electroacupuncture of Jin's three-needle treatment achieves the positive regulation on the abnormal lipid metabolism and insulin resistance. The hypoglycemic effect and the impro-ving effect in LDL-C and HDL-C of the catgut embedding therapy are superior to electroacupuncture.

[Guan's acupuncture technique and the rules of acupoints selection on leg].

Guan's acupuncture technique is a kind of special acupuncture methods developed and improved by GUAN Zheng-zhai. It has unique curative effects on hysterical paralysis, schizophrenia, madness, epilepsy and traumatic paraplegia, etc. This acupuncture technique has the characteristics of "deep" "transparent" "moving" and "sensing". The acupoints selection is different from that of twelve meridian acupoints. The deep insertion of acupuncture needles is applied at acupoints located in the wrist joint, ankle joint and below, while the penetration needling method is applied at acupoints located in the area which has relatively thick muscles, and where yin-meridian and yang-meridian are symmetric with each other. The horizontal and deep connection of acupoints and the adjustment effect of qi-blood and yin-yang are emphasized during treatment.

[Multiple symmetric lipomatosis: clinical analysis of 15 consecutive cases].

PURPOSE: The purpose of this study was to assess the clinical features and available treatment of multiple symmetric lipomatosis (MSL). METHODS: A cohort of 15 cases with MSL registered in the Affiliated Hospital of Qingdao University was reviewed. The etiology, clinical manifestations, treatments and prognosis were also investigated. RESULTS: All the cases were performed sectionalized excisions to cut off the lipoma localized in the neck under general anesthesia. During the follow up period, 13 out of 15 cases were cured after the excision with acceptable appearance and normal local function. Two cases with surgical complications, the one was hematoma, and the other was lymphatic leakage. There were 2 cases with relapses under our follow-up visit. CONCLUSION: Sectionalized lipoma excision under general anesthesia is a relative safe method for MSL.
