Objective To investigate the effect of low mechanical index diagnostic ultrasound and low acoustic pressure therapy on contrast agent microbubbles. Methods Microbubbles were irradiated by diagnostic ultrasound with low mechanical index(MI) and low energy therapy under different acoustic pressure. To obtain the images, and analyze the change of microbubble concentration,the movement trend of microbubbles under different MI and different acoustic pressure were analyzed, to estimated stable cavitation or inertial cavitation of microbubbles. Results Stable cavitation was the main form of microbubbles under low mechanical index (< 0.2) diagnostic ultrasound and low acoustic pressure (< 0.15Mpa). With the increase of mechanical index or acoustic pressure, stable cavitation and inertial cavitation coexisted. When mechanical index > 0.3 or sound pressure > 0.2MPa, microbubbles were mainly inertial cavitation. Conclusion The cavitation effects of microbubbles under low mechanical index and low acoustic pressure are different. With the increase of mechanical index or acoustic pressure, the damage of microbubbles increases, and main effect is the inertial cavitation.

Methods From March 2017 to August 2020,209 cases of cervicitis,169 cases of LSIL,131 cases of HSIL and 86 cases of cervical cancer confirmed by histology were selected as the research objects. The results of p16/Ki-67 staining and HPV E6/E7 RNA detection of the preoperative cytological samples were retrospectively analyzed and the p16/Ki-67 staining and HPV E6/E7 mRNA detection results were compared longitudinally. The positive rates of E6/E7mRNA and combined detection in different grades of cervical lesions were compared.The positive rates of p16/Ki-67 staining,HPV E6/E7 mRNA and combined detection in the same cervical lesions were compared horizontally.The differences in the diagnostic efficacy of p16/Ki-67 staining,HPV E6/E7 mRNA and combined detection in the diagnosis of HSIL+lesions were comprehensively evaluated. Results ①Longitudinal comparison:the positive rates of p16/ Ki-67 staining, HPV E6/E7mRNA and combined detection increased with the severity of cervical lesions(p16/Ki-67 staining:χ²=374.34,P<0.001;HPV E6/E7 mRNA detection:χ²=289.21,P<0.001;joint detection:χ²=343.90,P<0.001). ②Transverse comparison: in cervicitis, LSIL and cervical cancer groups,there were no significant differences in the positive rates of p16/Ki-67 staining, HPV E6/E7 mRNA and combined detection (all P>0.05). In the HSIL group,there was significant difference in the positive rate between p16/Ki-67 staining and combined detection (χ²=8.09,P=0.004)and the difference between HPV E6/ E7 mRNA and combined detection was statistically significant(χ²=11.30,P=0.001). ③The sensitivity of p16/Ki-67staining,HPV E6/E7 mRNA and combined detection in the diagnosis of HSIL+ was statistically significant(χ²=7.69,P=0.021). The sensitivity difference between p16/Ki-67 staining and combined detection was statistically significant(χ²=7.29,P=0.007);the sensitivity difference between HPV E6/E7 mRNA detection and combined detection method was statistically significant (χ²=4.84,P=0.028).

Objective To investigate the effect of electric acupuncture combined with Repetitive Transcranial Magnetic Stimulation (rTMS) treatment of poststroke depression with insomnia and analyze the therapeutic mechanism of this method. Methods 83 patients with PSD were randomly divided into the group of electric acupuncture combined with rTMS (n=32), rTMS group (n=32) and drug treatment group (n=32). The patients in the group of electric acupuncture combined with rTMS were given with the electric acupuncture treatment for 2 weeks on the basis of rTMS treatment, and also were regularly and continuously administrated with antidepressant drug (escitalopram citalopram). The rTMS group were only given with rTMS for 2 weeks, and the patients of the drug treatment group were administrated with the same antidepressant. At the baseline and 2th week, the 17-item Hamilton depression scale (17-HAMD), Pittsburgh Sleep Quality Index (PSQI) and polysomnography (PSG) were evaluated. Results The sleep parameters, PSQI scores and HAMD scores among three groups had no significant difference at baseline. After 2 weeks, the overall difference of HAMD score reduction between different treatment groups was statistically significant (P<0.001). The HAMD score reduction in the drug treatment group was less than that in the rTMS group and the electric acupuncture combined rTMS group (P<0.05), and the HAMD score reduction in the electric acupuncture combined rTMS group was greater than that in the drug group and the rTMS group (P<0.05). The overall difference of PSQI score reduction between groups was significant (P<0.05). The PSQI score reduction value of electric acupuncture combined with rTMS group was greater than that of the drug group and the rTMS group (P<0.05), while there was no significant difference in the PSQI score reduction value between the drug group and the rTMS group (P<0.05). The overall difference of total sleep duration (F=16.735,P<0.001) and sleep efficiency(F=87.548,P<0.001) evalted by PSG among groups was significant. The changes of both the total sleep duration and sleep efficiency of electric acupuncture combined with rTMS group was greater than that of the drug group and the rTMS group (P<0.001), while there was no significant difference neither in the changes of total sleep duration nor sleep efficiency between the drug group and the rTMS group before and after treatment among the groups (P>0.05). Conclusion Electroacupuncture combined with rTMS treatment may improve the efficacy of depression, sleep quality, the total sleep duration and sleep efficiency of PSD, and the effect is better than that of the drug treatment group and the rTMS group, which reflects the synergic effect of electroacupuncture combined with rTMS on PSD treatment.

Objective To observe the curative effect of low frequency electrical stimulation treatment on stroke hemiplegia, and analyze its influences on peripheral nerve electrophysiology and morphology of patients. Methods A total of 94 patients with stroke hemiplegia in the hospital were randomly divided into two groups by number table method, 47 cases in each group. The control group was given basic rehabilitation treatment, while experimental group was given early comprehensive rehabilitation treatment (low frequency electrical stimulation on basis of control group). The scores of Berg Balance Scale (BBS) and Fugl-Meyer assessment (FMA), joint (wrist, ankle) active range of motion (AROM), peripheral nerve electrophysiology [sensory conduction velocity (SCV), motor conduction velocity (MCV), dynamic electromyogram (EMG) ] and morphology [cross-sectional area (CSA) of carpal transverse median nerve (MN), width (W), thickness (T)] before and after treatment were compared between the two groups. Results After treatment, scores of BBS, upper and lower limbs FMA in experimental group were higher than those in control group (P<0.05), AROM of wrist and ankle was larger than that in control group (P<0.05). After treatment, SCV and MCV of common peroneal nerve and tibial nerve in experimental group were higher than those in control group (P<0.05), while co-contraction rates of biceps and gastrocnemius muscles were lower than those in control group (P<0.05). Before and after treatment, there were no differences in CSA and T of MN between the two groups (P>0.05). After treatment, W of MN in experimental group was greater than that in control group (P<0.05). Conclusion Low-frequency electrical stimulation combined with early comprehensive rehabilitation therapy may effectively increase the balance ability, joint range of motion and upper and lower limb function of stroke patients with hemiplegia, improve peripheral nerve electrophysiology and morphology, and reduce peripheral nerve injury.
