OBJECTIVES: To investigate the effects of the elongated needling at the points of hand and foot yang meridians and the Governor Vessel combined with the routine acupuncture therapy on pain, balance function and muscle strength of the patients with post-stroke hemiplegia and central post-stroke pain (CPSP), and to investigate whether its therapeutic mechanism is related to antioxidant damage. METHODS: Ninety-four patients with post-stroke hemiplegia and CPSP admitted from March 2020 to September 2021 were divided into a trial group (47 cases, 1 cases dropped out) and a control group (47 cases 3 cases dropped out). In the control group, the rehabilitation exercise combined with routine acupuncture therapy was used, and in the trial group, on the base of the treatment as the control group, the elongated needling at the points of hand and foot yang meridians and the Governor Vessel was supplemented. In the two groups, the treatment was given once daily, and 1 course of treatment was composed of 14 days, a total of 6 courses were required in the trial. Separately, before treatment, and 1, 2 and 3 months after treatment, between two groups, the score of visual analogue scale (VAS) and that of Berg balance scale (BBS), as well as muscle strength were compared；the neural function was evaluated using the national institutes of health stroke scale (NIHSS) and the serum contents of nitricoxide synthase (NOS), superoxide dismutase (SOD) and malondialdehyde (MDA) were detected by ELISA in the patients. RESULTS: Compared with those before treatment, VAS score and NIHSS score were all decreased (P<0.05) in the trial and the control group after 1 month, 2 months and 3 months of treatment, and BBS score was increased (P<0.05)；and the case proportion of muscle strength grade 4 and 5 was higher (P<0.05) in the trial group. In the control group, the proportion of grade 4 increased after treatment for 2 months (P<0.05), and that of grade 4 and 5 increased after treatment for 3 months (P<0.05). The serum contents of NOS and SOD were increased (P<0.05), and MDA was decreased (P<0.05) after 3 months of treatment in the two groups. In comparison with the control group at the same time point, VAS score and NIHSS score were lower (P<0.05), BBS score higher (P<0.05) and the muscle strength grade was improved (P<0.05, P<0.01) after 1, 2 and 3 months of treatment, respectively；and the serum contents of NOS and SOD increased (P<0.05), and MDA decreased (P<0.05) after 3 months of treatment in the trial group. CONCLUSIONS: The elongated needling at the points of hand and foot yang meridians and the Governor Vessel, combined with the routine acupuncture therapy alleviates CPSP, improves balance and muscle strength and promotes the recovery of neural function in the patients with post-stroke hemiplegia, the mechanism may be related to antioxidant damage.

Chai Hu oral liquid enhances the immune functions of both spleen and bursa of Fabricius in heat-stressed broilers through strengthening TLR4-TBK1 signaling pathway.

Heat stress can affect the poultry production and immune status of broilers. Heat stress disrupts intestinal integrity and increases intestinal inflammation, which is related with body immune dysfunction. Chai Hu oral liquid used as an antipyretic and anti-inflammatory drug is widely used in exogenous fever of poultry, but its resistance to heat stress and the mechanism is still unclear. In this study, a chronic heat stressed broilers model was established to explore the mechanisms of broilers' immune function changes and the effects of Chai Hu oral liquid. In this study, a total of 480 broilers were randomly divided into 6 groups with 80 replicates. Heat stress (HS) group broilers were stressed at 35 ± 2°C for 5 or 10 consecutive d with 6 h/d. Heat stressed (for 5 or 10 d) broilers were given with Jieshu KangreSan (Positive), Chai Hu oral liquid high, middle and low dosage (CH-High, CH-Mid, CH-Low) by oral administration. Birds in control group were treated with the same volume of PBS only in 25 ± 2°C. All birds were sacrificed at last heat stress challenged day. Changes in immune function were assessed by immune organs index, serum IFN-γ level, gene and protein expressions of immune factors in spleen and bursa of Fabricius. Results from this experiment showed that heat stress enhanced the immune organs' edema by directly increased the organs indexes of spleen and bursa of Fabricius in broilers. Heat stress for 10 d also increased bursa of Fabricius HSP70 protein level and significantly lowered the spleen and bursa of Fabricius proteins expressions of IFN-α, IFN-ß, and IFN-γ in broilers. The IFN-ß and IFN-γ protein levels in spleen and bursa of Fabricius also decreased in heat stressed broilers for 5 d. The gene and protein expressions of TLR4 and TBK1 markedly decreased in spleen and bursa of Fabricius of broilers treated with chronic heat stress. Chai Hu oral liquid reduced edema of immune organs and elevated TLR4-TBK1 signaling pathway to release immune factors. Above results indicated that chronic heat stress induced impaired immune function by inhibiting TLR4-TBK1 signaling pathway, and Chai Hu oral liquid had effective protection of body's immune ability by enhancing this signaling pathway.
