ABSTRACT
Objective:To evaluate the intestinal function in rats with exertional heat stroke (EHS) and explore the protective role of Ruifuping pectin (RFP) against heat related intestinal mucosal injury.Methods:One hundred and twenty healthy special pathogen free (SPF) male Sprague-Dawley (SD) rats were randomly divided into normothermic control group, EHS model group, hyperthermic plus drinking water group (H 2O+EHS group) and hyperthermic plus pectin group (RFP+EHS group) with 30 rats in each group. The rats in the H 2O+EHS group and RFP+EHS group were given water 20 mL/kg or RFP 20 mL/kg orally for 5 days during adaptive training period. After 1 week, the temperature control range was adjusted to (37±1)℃ using the temperature control treadmill, and the rat model of EHS was reproduced by one-time high temperature exhaustive exercise. No rehydration intervention was given during the training adaptation period in the EHS model group. The rats in the normothermic control group were maintained to room temperature (25±2)℃ and humidity (55±5)% without other treatment. Behavior tests including withdraw response, righting, and muscle strength were performed immediately after onset of EHS. Blood of inferior vena cava was collected, and the serum inflammatory cytokines [tumor necrosis factor-α (TNF-α) and interleukins (IL-6, IL-1β, IL-10)] and activity of diamine oxidase (DAO) were detected by enzyme linked immunosorbent assay (ELISA). The intestinal mucosa was collected, after hematoxylin-eosin (HE) staining, and Chiu score was performed to assess EHS induced pathological changes under light microscope. Results:The rats in the EHS model group had behavioral, inflammatory and pathological changes, such as delayed withdraw response and righting, decreased forelimb pulling, increased inflammatory index, and obvious intestinal mucosal injury, which indicated that the reproduction of the EHS model was successful. There was no significant difference in above parameters between the H 2O+EHS group and the EHS model group except that the inflammatory index in the RFP+EHS group was improved. Compared with the EHS model group, the withdraw reflex to pain and righting after RFP pretreatment in the RFP+EHS group were significantly improved (righting score: 1.4±0.2 vs. 0.3±0.2, withdraw reflex to pain score: 1.0±0.1 vs. 0.2±0.1, both P < 0.05), the muscle strength was significantly increased (N: 13.0±0.5 vs. 8.2±0.6, P < 0.01). The levels of pro-inflammatory factors in the RFP+EHS group were significantly lower than those in the EHS model group [TNF-α (ng/L): 67.5±9.2 vs. 194.3±13.7, IL-6 (ng/L): 360.0±54.1 vs. 981.2±84.4, IL-1β (ng/L): 33.7±9.0 vs. 88.7±6.1, all P < 0.01], while the level of anti-inflammatory factor IL-10 was higher than that in the EHS model group (ng/L: 208.7±10.5 vs. 103.7±7.0, P < 0.01). The degree of intestinal mucosal injury in the RFP+EHS group was less severe than that in the EHS model group, and the Chiu score and DAO were significantly lower than those in the EHS model group [Chiu score: 1.5±0.2 vs. 3.8±0.0, DAO (U/L): 83.7±6.7 vs. 128.7±10.5, both P < 0.05]. Conclusions:High temperature training can damage the intestinal barrier function, and induce endotoxemia and systemic inflammatory response syndrome (SIRS) in rats. Oral prophylactic RFP can protect the intestinal barrier function, alleviate SIRS, and promote the recovery of basic nerve reflex and muscle strength after the occurrence of EHS in rats.
ABSTRACT
@#Objective To explore the effects of Jin's Three-needle Acupuncture combined with occupational therapy on function of upper limbs for stroke patients with hemiplegia. Methods 90 patients with stroke were randomly divided into control group (n=30), observation group (n=30) and experiment group (n=30). The control group received routine rehabilitation, the observation group received occupational therapy in addition, and the experiment group received Jin's Three-needle Acupuncture and occupational therapy in addition. They were assessed with Fugl-Meyer Assessment (FMA) of upper limbs and Barthel index (BI) before and 4 weeks after treatment. Results The scores of FMA and BI improved in all the groups after treatment (P<0.001). The difference of scores of FMA and BI before and after treatment were more in the experiment group than in the observation group (P<0.001), observation group than the control group (P<0.001). Conclusion Jin's Three-needle Acupuncture combined with occupational therapy can further improve the motor function of upper limbs and activities of daily living for stroke patients with hemiplegia.

ABSTRACT
ObjectiveInvestigate the shape of plug mesh and patch after plug-mesh hernia repair and discuss the necessity of improving the operative procedures. MethodsUse B ultrasound to investigate the shape of plug-mesh and patch after mesh plug hernia repair and review the patients medical record,evaluate how operative procedures affect the shape of patch and the results. ResultsIn 4 of the 16 cases,the distant end of patches overlapped the pubic margin,in the remaining 12cases the distant end of patches didn't reach the pubic margin. When changing the cut-in direction of B ultrasound probe,a wide and dense shadow was discovered in 8 cases whose patches didn't reach the pubic margin. Between the pubic margin and dense shadow there was a space showing low dense shadow. These photocopies showed that the patches had folded up or crimped. In 11 of 12 cases,the patches didn't fix on pubic margin or cut shorter during operation. Conclusion It is suggested to fix the distant end of patch on the aponeurosis tissue of pubic in the procedure of mesh plug hernia repair,and combine the plug-mesh repair with Lichtenstein repair.
