Objective:To observe the clinical efficacy of brain-benefiting and collateral-unblocking needling technique for chronic alcoholic gastritis complicated with depression. Methods:A total of 92 cases with chronic alcoholic gastritis complicated with depression were included in this trial. They were randomly allocated into an observation group (n=46) and a control group (n=46) by random number (envelope) method. Patients in the observation group received the brain-benefiting and collateral-unblocking needling technique. Scalp points included Shenting (GV 24), Xinhui (GV 22), Qianding (GV 23), Baihui (GV 20), Chengguang (BL 6), Tongtian (BL 7) and Luoque (BL 8). Body points included Neiguan (PC 6), Zusanli (ST 36), Zhongwan (CV 12), Gongsun (SP 4), Shenmen (HT 7), Daling (PC 7), Qimen (LR 14), Xinshu (BL 15) and Taichong (LR 3). The control group only received the same body acupuncture as the observation group. The treatment was conducted once a day, 30 min for each treatment, and 10 times made up a course of treatment. The efficacy was observed after 3 courses of treatment, and there was a 2-d interval between two courses. Results:After 3 courses of treatment, the clinical symptoms and gastroscopic features were significantly improved in the observation group than that in the control group. The clinical efficacy, self-rating anxiety scale (SAS) and self-rating depression scale (SDS) were significantly better than those in the control group (allP<0.05). Conclusion:The brain-benefiting and collateral-unblocking needling technique can significantly improve clinical symptoms in patients with chronic alcoholic gastritis complicated with depression and substantially alleviate their gastroscopic features, anxiety and depression.

Objective:To observe the effect of electroacupuncture (EA) on the expression of erythropoie-tin-producing hepatocyte receptor B2 (EphB2) in the cortex around the infracted area of middle cerebral artery occlusion (MCAO) rats at different timing, and to reveal the possible mechanism of acupuncture in the treatment of cerebral ischemia.
Methods:A total of 180 male Sprague-Dawley (SD) rats were randomly divided into a sham operation group, a model group, an acupoint group and a non-acupoint group, with 45 rats in each group. Rats in each group were further divided into three subgroups: postoperative 3 d, postoperative 14 d and postoperative 21 d groups, with 15 rats in each subgroup. The MCAO model was made by the modified occlusion method. The neurological function score, 2,3,5-triphenyl tetrazolium chloride (TTC) staining, immunohistochemistry assay, immunofluorescence double labeling method and Western blot were used to detect the corresponding indicators.
Results:The neurological impairment of rats was most obvious at postoperative 3 d, and then gradually improved with time, which was more significant in the acupoint group (P<0.05). The change of infarcted volume was consistent with the neurological function impairment. The number of EphB2 positive cells (EphB2+) around the infarcted area was decreased significantly at postoperative 3 d, and then gradually improved with time, which returned to the same level as that in the sham operation group at postoperative 21 d. The increase was most significant in the acupoint group (P<0.05), and the positive cell number was higher than that in the sham operation group (P<0.01). Western blot and immunohistochemistry results were basically consistent. Immunofluorescence displayed that EphB2+ and postsynaptic density-95 positive (PSD-95+) were co-expressed, after the MCAO operation, in the cortical neuron around the infracted area, and the number of co-expressing cells was increased gradually with time, which was most significant in the acupoint group (P<0.05).
Conclusion:Electroacupuncture at Ganshu (BL 18) and Shenshu (BL 23) can significantly improve the neurological function and cerebral infarcted volume ratio of MCAO rats, which may be related to the activation of EphB2 expression in cortex around the infracted area and the promotion of synaptic remodeling.

Objective:To observe the clinical efficacy of warm needling moxibustion plus flash cupping for remission-stage peripheral facial paralysis (FP) due to wind-cold.
Methods:Fifty eligible patients were randomized into a warm needling moxibustion group and an acupuncture-cupping group, 25 cases in each group. The warm needling moxibustion group was intervened by acupuncture at Fengchi (GB 20), Yangbai (GB 14) towards Yuyao (EX-HN 4), Xiaguan (ST 7), Dicang (ST 4) towards Jiache (ST 6), Quanliao (SI 18), and Hegu (LI 4), plus warm needling moxibustion at Quanliao (SI 18); the acupuncture-cupping group received flash cupping on the affected side in addition to the intervention given to the warm needling moxibustion group. The two groups were both treated once a day, 10 times as a treatment course, for 3 courses in total. The House-Brackmann (H-B) facial nerve grading system was observed before and after the intervention to evaluate the facial nerve function in the two groups, and the therapeutic efficacies were also compared between the two groups.
Results:The two treatment protocols both can promote the recovery of facial nerve function. The total effective rate was 92.0% in the acupuncture-cupping group versus 72.0% in the warm needling moxibustion group, and the between-group difference was statistically significant (P<0.05).
Conclusion:Warm needling moxibustion plus flash cupping can produce a more significant efficacy than dry warm needling moxibustion in treating remission-stage peripheral FP due to wind-cold.
