Clinical effect of acupuncture along fascia, meridians, and nerves combined with ultrasound-guided paravertebral nerve block in the treatment of postherpetic neuralgia: a randomized parallel-controlled study.

OBJECTIVE: To observe the clinical efficacy of acupuncture along fascia, meridians, and nerves combined with ultrasound-guided nerve blockage in the treatment of postherpetic neuralgia. METHODS: A total of 61 outpatients with post-chest and back herpes zoster neuralgia were recruited in the Department of Pain at the Xiyuan Hospital, China Academy of Chinese Medical Sciences from May 2019 to June 2021. They were randomly divided into two groups. Thirty-one patients in the control group were treated with ultrasound-guided thoracic paravertebral nerve block (PVB) alone, one patient declined to continue during treatment ( 30), and thirty patients in the observation group received the acupuncture along the fascia, meridians, and nerves combined with ultrasound-guided PVB treatment ( 30). Both control and observation group received treatment weekly for 4 weeks. The medical history data such as age, sex, presence or absence of comorbidities and disease course were analyzed. The visual analog scale (VAS) score was used to assess the pain degree of two groups at T0 (before treatment), T1 (1-time treatment ended), T2 (2 times treatment ended), T3 (3 times treatment ended), and T4 (4 times treatment ended). The sleep state was examined by Pittsburgh Sleep Quality Index (PSQI) before and after the study. RESULTS: There was no significant difference in general conditions between the control group and the observation group (> 0.05). The VAS score in both control and observation group was decreased in a time-dependent manner after 1-4 weeks of treatment. There were no significant differences in VAS scores between the two groups after 1 or 2 weeks of treatment ( > 0.05). After 3 and 4 weeks of treatment, the VAS score was significantly decreased in the observation group compared with that in the control group ( < 0.001). In addition, the reduction in VAS score (after treatment-before treatment) between the two groups was statistically significant [D value: -1.53, 95% (-2.32, 0.74), < 0.001]. Furthermore, the sleep state of patients in both groups markedly improved and much obvious in the observation group than that in the control group ( < 0.05). CONCLUSION: These results suggest that a combination of acupuncture along fascia, meridians, and nerves with ultrasound-guided PVB treatment is more effective than ultrasound-guided PVB treatment alone.

Single Cell Traction Force Measured by Foldable Microplates / 医用生物力学

Objective To fabricate a foldable microplate for single cell culture and establish finite element model of the folding microplate, so as to calculate traction force of single cells during contraction in three-dimensional (3D) state.Methods The folding angle of the microplate casued by cell traction force was calculated. Then the relation between bending moment and folding angle as well as the relation between traction force and bending moment were derived by using finite element simulation, so as to realize the characterization of traction force for singel cell in 3D state.Results The folding angles of the microplate with HSF and MC3T3-E1 cells in 3D state were 73°-173° and 49°-138°, respectively. The single cell traction forces of HSF and MC3T3-E1 cells were 55-210 nN and 52-161 nN, respectively.Conclusions The proposed method for measuring traction force of single cells in 3D state by fabricating the foldable microplate for single cell culture will provide some references for further development of calculating traction forces in 3D cell adhesion, spreading and migration.

The Thinking of Promoting the Medical Students' Humanities Quality Training in 21st Century / 中华医学教育探索杂志

Medical science is the science which closely combines scientific knowledge with humanistic spirit. Becausemodern science and technology have been more and more applied in medical research and practice, the medical sciencehas been developed rapidly. But medical science calls us to concern more about medical humanistic spirit, so how wecombine medical scientific knowledge with humanistic spirit is a very important topic in our medical university education.[
