RESUMEN
OBJECTIVE: To observe the effect of Shugan Tiaoshen acupuncture (acupuncture for soothing the liver and regulating the mentality) combined with western medication on depression and sleep quality in the patients with depression-insomnia comorbidity due to COVID-19 quarantine, and investigate the potential mechanism from the perspective of cortical excitability. METHODS: Sixty patients with depression-insomnia comorbidity due to COVID-19 quarantine were randomly divided into an acupuncture group and a sham-acupuncture group, 30 cases in each one. The patients of both groups were treated with oral administration of sertraline hydrochloride tablets. In the acupuncture group, Shugan Tiaoshen acupuncture was supplemented. Body acupuncture was applied to Yintang (GV 24+), Baihui (GV 20), Hegu (LI 4), Zhaohai (KI 6), Qihai (CV 6), etc. The intradermal needling was used at Xin (CO15), Gan (CO12) and Shen (CO10). In the sham-acupuncture group, the sham-acupuncture was given at the same points as the acupuncture group. The compensatory treatment was provided at the end of follow-up for the patients in the sham-acupuncture group. In both groups, the treatment was given once every two days, 3 times a week, for consecutive 8 weeks. The self-rating depression scale (SDS) and insomnia severity index (ISI) scores were compared between the two groups before and after treatment and 1 month after the end of treatment (follow-up) separately. The cortical excitability indexes (resting motor threshold [rMT], motor evoked potential amplitude [MEP-A], cortical resting period [CSP]) and the level of serum 5-hydroxytryptamine (5-HT) were measured before and after treatment in the two groups. RESULTS: After treatment and in follow-up, SDS and ISI scores were decreased in both groups compared with those before treatment (P<0.05), and the scores in the acupuncture group were lower than those in the sham-acupuncture group (P<0.05), and the decrease range in the acupuncture group after treatment was larger than that in the sham-acupuncture group (P<0.05). After treatment, rMT was reduced (P<0.05), while MEP-A and CSP were increased (P<0.05) in the acupuncture group compared with that before treatment. The levels of serum 5-HT in both groups were increased compared with those before treatment (P<0.05). The rMT in the acupuncture group was lower than that in the sham-acupuncture group, while MEP-A and CSP, as well as the level of serum 5-HT were higher in the acupuncture group in comparison with the sham-acupuncture group (P<0.05). CONCLUSION: Shugan Tiaoshen acupuncture combined with western medication can relieve depression and improve sleep quality in the patients with depression-insomnia comorbidity due to COVID-19 quarantine, which is probably related to rectifying the imbalanced excitatory and inhibitory neuronal functions.

OBJECTIVE: To investigate the effect of electroacupuncture (EA) on the morphology and microstructure of spinal cord tissue, the expression of serum exosomes, and the pro-inflammatory factors interleukin (IL)-1ß and IL-6 in spinal cord of rats with spinal cord injury (SCI), so as to explore the underlying mechanism of EA in the treatment of SCI. METHODS: Twenty-four female Wistar rats were randomly divided into sham operation group, model group, EA group, EA+GW4869 group, with 6 rats in each group. The SCI model was established by impinging spinal cord at T10 with a hammer, while the vertebral lamina was only opened without impingement for rats in sham operation group. Rats in EA group received EA intervention at "Jiaji"(EX-B7) acupoints at bilateral T9 and T10 (0.4-0.6 mA, 100 Hz), 3 h after modeling, once a day, for 7 concecutive days. Besides the treatment as EA group, rats in the EA+GW4869 group received injection of exosome inhibitor GW4869(200 µL, 300 µg/mL) once every 2 days from the day before modeling. Motor function of hind limbs of rats was evaluated using BBB scores. The histopathological changes of spinal cord were observed under light mircoscope after H.E. staining. Microstructure of spinal cord was observed and extracted serum exosomes were identified by using transmission electron microscopy. The expression of exosome marker proteins in serum exosomes, the levels of IL-1ß and IL-6 in spinal cord were detected by Western blot. RESULTS: H.E. stanining showed severe tissue looseness, inflammatory cell infiltration, cellular hydropic degeneration in spinal cord of the model group, which were relatively milder in the EA and EA+GW4869 groups. Under transmission electron microscopy, there were nerve fiber disintegration, myelin sheath structure dispersion, axonal atrophy with submembrane edema and widened space, and mitochondrial swelling in spinal cord of rats in the model group, with the lesions in EA group milder than EA+GW4869 group, which were both moderate. Typical exosomes were detected by transmission electron microscope in the extracted serum of rats in each group after ultracentrifugation. Compared with the sham operation group, the motor function scores was significantly decreased (P<0.01), the expression of IL-6 and IL-1ß in the spinal cord was significantly increased (P<0.01), while the expression of serum exosome marker protein CD81 was slightly increased in rats of the model group. Compared with the model group, the motor function scores was significantly increased (P<0.01), the expression of IL-6 and IL-1ß in the spinal cord was significantly decreased (P<0.01) in rats of the EA and EA+GW4869 group, while the expression of serum CD81 protein was slightly increased in rats of the EA group. Compared with the EA+GW4869 group, the expression of IL-6 and IL-1ß in the spinal cord was significantly decreased (P<0.01), while the expression of serum CD81 protein was slightly increased in rats of the EA group. However, there was no significance in expression of CD81 between each group mentioned above. CONCLUSION: EA can promote the secretion of serum exosomes and inhibit the expression of pro-inflammatory cytokines IL-6 and IL-1ß, so as to improve the microenvironment of injured spinal cord and SCI.

Professor LI Xiaoning's experience for post-stroke dysphagia treated with penetrating-needling and swallowing technique of acupuncture is summarized in this paper. The key pathogenesis of this disease is dysfunction of zangfu organs, impairment of the house of mental activity and dysfunction of meridian sinew. Innovatively, the anatomic structure related to swallowing is divided into three zones. Based on the distributions of heart, kidney and stomach meridians on the neck, three lines are determined. Hence, the theory of "three-zone and three-line" as well as the penetrating-needling and swallowing technique of acupuncture are put forward. In this paper, the theoretic evidences of penetrating-needling and swallowing technique of acupuncture, point selection and manipulation in treatment of post-stroke dysphagia are introduced.

OBJECTIVE: To observe the effect of electroacupuncture (EA) of "Jiaji" (EX-B 2) on limb locomotor function and expression of Ras homolog gene family member A (RhoA), Rho-associated kinase â ¡ (ROCK â ¡) and myosin light chain (MLC) proteins in the anterior horn of spinal cord in acute spinal cord injury (ASCI) rats, so as to explore its mechanisms under-lying improvement of SCI-induced limb locomotor dysfunction. METHODS: Forty-eight female Wistar rats were randomly divided into sham operation (sham), ASCI model (model), EA EX-B 2 (EA) and ROCK inhibitor (Fasudil) groups which were further divided into 14 d and 28 d subgroups (n=6 in each). The ASCI model was made by using weight drop striking method. Three hours after modeling, EA (100 Hz, 0.4, 0.6 mA) was applied to EX-B 2 (T 9, T 11) for 30 min, once daily for 14 d and 28 d, respectively. The ROCK inhibitor (hydrochloride Fasudil, 10 mg/kg) was administrated by intraperitoneal injection immediately after modeling, once a day, continuously for 14 d or 28 d. The expression of RhoA, ROCK â ¡ and MLC proteins in the spinal cord anterior horn tissue (T 10) was detected by immunohistochemistry. The rats' hindlimb locomotor function was assessed according to Basso, Beattie and Bresnahan (BBB) locomotor rating scale (21-points). RESULTS: After ASCI, the BBB scores were significantly lower in the model group than in the sham group on day 14 and 28 (P<0.05), and obviously higher in the EA and inhibitor groups than in the model group (P<0.05), suggesting an improvement of the hindlimb locomotor function after EA intervention or suppression of ROCK. Immunohistochemical results indicated that the numbers of RhoA, ROCK â ¡ and MLC immune-reaction positive cells in the anterior horn of spinal cord were significantly more in the model group than in the sham group (P<0.05), and remarkably decreased in both EA and inhibitor groups on day 14 and 28 relevant to the model group (P<0.05). The therapeutic effects of EA were markedly weaker than those of inhibitor Fasudil in up-regulating BBB score and down-regulating the number of RhoA, ROCK â ¡ and MLC positive cells (P<0.05). CONCLUSION: EA of EX-B 2 can improve the hindlimb locomotor function in ASCI rats, which may be associated with its effect in down-regulating the expression of RhoA, ROCK â ¡ and MLC proteins (i.e., inhibiting the RhoA/ROCK signaling pathway) in the anterior horn of spinal cord.

During a survey on chemical constituents of Abies nukiangensis, seven previously unreported compounds, including six triterpenes (1-6) and one phenol (7) were isolated and characterized, together with 37 known miscellaneous chemical constituents. The structures of compounds 1-7 were established mainly by extensive analysis of the 1D and 2D NMR, as well as HRMS data. The absolute configurations of compounds 1 and 8 were confirmed unambiguously by the Cu-Kα X-ray crystallography. Compounds 3 and 8-10 showed significant anti-hepatitis C virus effects with EC50 values of 3.73, 2.67, 1.33 and 2.25µM, respectively.
