Objective@#To explore the application value of virtual touch tissue imaging quantification(VTIQ) technology in initial polymyositis(PM).@*Methods@#Sixteen PM patients collected from February 2016 to March 2019 in Wenzhou People′s Hospital were selected as PM group, and 33 healthy subjects as healthy control group. After gray and color Doppler ultrasound, the shear wave velocity(SWV) values of target muscle and control muscle in the same side of affected limb were measured by VTIQ technique. Maximum velocity(Vmax) and minimum velocity(Vmin) were measured, average velocity(Vmean) and standard deviation(SD) were calculated, and compared between the two groups. SWV difference and ratio between target muscle and control muscle were calculated, and creatine kinase(CK) was detected in the same day.@*Results@#Part of PM patients had abnormal ultrasonographic manifestations of full muscle shape (31.25%), increased or decreased echo of muscle bundles (56.25%), blurred muscle texture (25.00%) and increased blood flow signals (37.50%). There were significant differences in Vmin, SD, and Vmax difference, Vmin difference, Vmean difference, and Vmax ratio, Vmin ratio, and Vmean ratio between PM group and healthy control group (all P<0.01). The ROC curve analysis showed that the diagnostic efficiency of Vmin was lower than those of Vmin difference and Vmean difference, Vmin ratio and Vmean ratio with very close diagnostic efficiencies of the latter four parameters. The correlation analysis showed that Vmin difference and Vmean difference were moderately correlated with CK value(r=0.512, 0.601; all P<0.05).@*Conclusions@#Reduced VTIQ values or relative reduction of VTIQ values compared with other non-involved muscles are the manifestations of initial PM, VTIQ have certain diagnostic efficacy for initial PM.

Acupoint compatibility is a basic element for acupuncture prescription and an important link for clinical acupuncture workers to obtain a therapeutic effect. Studying factors influencing the effect of acupoint combination and ascertaining its concept and connotation are of important significance for studying the mechanism of acupuncture action. By sorting out, summing up and analyzing relevant modern literature, it is found that factors influencing the effect of acupoint combination are those affecting the therapeutic effects of combination of two or more than two acupoints. Its contents include five aspects: combination mode, combination effect, stimulation method, time factor and body status. Analysis and induction show that acupoint selection is the primary task in studying factors influencing the effect of acupoint combination.

Primary insomnia (PI) is now a nonorganic sleep disorder that seriously affects the quality of life of people around the world and attracts the attention of medical circles at home and abroad. Western medicine treatment has side effects such as drug dependence and withdrawal rebound and cannot obviously improve the quality of sleep and life, while acupuncture has a good therapeutic effect on PI. This article explores the latest research status of acupuncture treatment for PI. Chinese Journal Net (CNKI, VIP and Wanfang) was mainly searched to retrieve and sum up recent five years’ literature about the study of acupuncture treatment for PI. The results show that acupuncture has an advantage in producing a short-term marked therapeutic effect on PI and being of a high total efficacy rate and can effectively treat primary insomnia.
