Objective To observe changes of the partial oxygen pressure in the deep tissues along the Large Intestine Meridian (LIM) during acupuncture stimulation,so as to reveal the characteristics of energy metabolism in the tissues along the LIM. Methods Thirty-one healthy volunteer subjects were enlisted in the present study. Partial oxygen pressure (POP) in the tissues (at a depth of about 1.5 cm) of acupoints Binao (LI 14),Shouwuli (LI 13),Shousanli (LI 10),2 non-acupoints [the midpoints between Quchi (LI 11) and LI 14,and between Yangxi (LI 5) and LI 11) of the LIM,and 10 non-meridian points,1.5-2.0 cm lateral and medial to each of the tested points of the LIM was detected before,during and after electroacupuncture (EA) stimulation of Hegu (LI 4) by using a tissue oxygen tension needle-like sensor. Results In normal condition,the POP values in the deep tissues along the LIM were significantly higher than those of the non-meridian control points on its bilateral sides. During and after EA of Hegu (LI 4),the POP levels decreased significantly in the deep tissues along the LIM in comparison with pre-EA (P0.05). Conclusion POP is significantly higher in the deep tissues along the LIM of healthy subjects under normal conditions,which can be downregulated by EA of Hegu (LI 4),suggesting an increase of both the utilization rate of oxygen and energy metabolism after EA.

Objective:To investigate the effect of high-frequency repetitive transcranial magnetic stimulation(rTMS)on cue attention in male patients with alcohol use disorder (AUD) after the acute withdrawal.Methods:A total of 90 male patients AUD who were hospitalized in the Second Affiliated Hospital of Kunming Medical University and Psychiatric Hospital of Yunnan province from May 2020 to December 2020 were enrolled, then they were divided into study group and control group using random number table.Because 18 cases fell out during the study, 36 cases were included in each of the two groups.After the alcohol withdrawal syndrome eliminated, the study group received high-frequency rTMS at 10 Hz for 14 consecutive days, and the control group was administrated by sham rTMS.At baseline and after true or sham rTMS, the cognitive psychology experiment Oddball paradigm was completed, and the behavioral data of the subjects were collected.Paired-sample t-test was used to compare the changes of the two groups before and after treatment.Data analysis were conducted using SPSS 21.0 software. Results:There was no statistical difference between the study group and the control group in terms of drinking level, cognition level and demographic data(all P>0.05). In the Oddball paradigm, compared with the control group((526.72±75.30)ms, (0.98±0.02))the reaction time((497.93±64.51)ms, t=3.145, P=0.008) and accuracy rate((0.99±0.01), t=-2.803, P=0.016) in alcohol-related cues were significantly improved in the study group after rTMS intervention, but in the control group, there were no statistical differences(both P>0.05), whether the cue was alcohol related or not. Conclusion:The results suggest that the rTMS can enhance the attention bias of alcohol-related cues and change the impulse process partly.
