Objective:To observe the effects of electroacupuncture at "Shenting", "Benshen" and "Baihui" acupoints on the mechanical pain threshold and JAK/PI3K/TRPV1 pathway in the trigeminal ganglion of rats with trigeminal neuralgia model; To explore the related mechanism.Methods:Totally 36 male SD rats were divided into sham-operation group, model group and electroacupuncture group using random number table method, with 12 rats in each group. Except for the sham-operation group, rats in the model group and electroacupuncture group were modeled by infraorbital nerve chronic constriction injury. In the electroacupuncture group, electroacupuncture was performed at "Shenting", "Benshen" and "Baihui" 14 days after surgery, 20 min every day, once every other day, and every 3 times for 1 course of treatment with an interval of 2 d between each course of treatment. A total of 2 courses of treatment were performed. VonFrey fiber wire was used to measure the mechanical pain threshold of rat whisker pads. HE staining was used to observe the morphology and structure of trigeminal ganglion of rats in each group. Immunohistochemistry and Western blot method were used to observe the protein expressions of JAK, PI3K and TRPV1 in trigeminal ganglion of rats, and the serum level of IL-6 was detected in the serum of rats by ELISA.Results:Compared with the model group, the pain threshold of the electroacupuncture group increased significantly ( P<0.05), and the infiltration of inflammatory cells and demyelination in the trigeminal nerve ganglion decreased, and the positive expressions of JAK, PI3K, and TRPV1 in the trigeminal ganglion decreased ( P<0.05 or P<0.01), the protein expressions of JAK2, PI3K, and TRPV1 decreased ( P<0.05 or P<0.01), and the serum IL-6 level decreased ( P<0.01). Conclusions:Electroacupuncture at "Shenting", "Benshen" and "Baihui" may play an analgesic role by regulating IL-6 levels and inhibiting the activation of JAK/PI3K/TRPV1 signaling pathway.

Objective:To observe the clinical effect of acupuncture treatment based on Tiaoshen theory for the patients with functional dyspepsia (FD) and depression with liver-stomach disharmony syndrome. Methods:A total of 76 FD patients from May 2018 to August 2019 were randomly divided into 2 groups with 38 patients in each group. In the routine group, acupoints were selected routinely, and in Tiaoshen group, acupoints were selected by Tiaoshen theory. Both groups were treated for 28 days. The results were evaluated by Nepean Dyspepsia Index (NDI), TCM Syndrome Score and Hamilton Depression Scale-24 (HAMD-24). Results:The total effective rate of both groups was 94.6% (35/37) in Tiaoshen group and 75.0% (27/36) in routine group. There was significant difference between the two groups ( χ2=6.125, P=0.011). The NDI in Tiaoshen group was significantly lower than that of routine group ( t=3.038, P=0.003). The scores of interference domain, control domain, food and beverage domain and sleep disturbance domain in Tiaoshen group were significantly higher than those in routine group ( t=3.096, 2.460, 2.225, 2.732, P<0.05); the TCM Syndrome Score in Tiaoshen group was significantly lower than that of routine group ( t=3.241, P=0.002), and that of HAMD-24 was significantly lower than that of routine group ( t=2.767, P=0.007). Conclusion:Treatment based on Tiaoshen theory can improve the quality of life of FD patients in the fields of interference, control, food and beverage and sleep disturbance, and reduce the patients’depression.
