Objective Extrapolate the relationships between the width of circumferential rectal mucosa re-sected and the method of either performing single purse-string or performing double purse-string during per-forming the procedure for prolapse and hemorrhoids (PPH), and to assess the impact of both the level of sta-ple line and the width of rectal mucosa resected on clinical outcomes after stapled hemorrhoidpexy. Meth-ods Twenty-eight adult patients with Ⅲ-Ⅳ hemorrhoids were assigned to two groups: 15 patients using sin-gle pursestring and the remaining 13 patients using double purse-string. The mucosal width of doughtnuts of both groups were measured and the data recorded. The doughtnuts resected were sent to pathology examina-tion after stapled hemorrhoids pexy to identify whether or not the specimens involved the smoth muscles. The demographic complications (bleeding, postoperative pain, urinary retention, fecal urgency) were compared and statistically analysed between the two groups, respectively. Results There were no statistical differ-ences between the two groups in terms of postoperative short-term results and complication rates, as well as the proportion of involving smooth muscle in specimens(P >0.05). However, when compared the width of doughtnuts resected in single-pursestring group was smaller than that in double-parse-string group (P < 0. 01). Conclusion The single or double-purse-string suture in PPH can control the width of resected rectal mucosa.

Hypoxic-ischemic brain damage is a serious complication of perinatal asphyxia. Enriched environment is the living condi-tions for the promotion of feeling, cognition and behavior. Enriched environment may promote the repairing of hypoxic-ischemic brain dam-age in term of praxiology, morphology and molecular biology, that enriched environment may regulate the secretion and release of various factors, and enhance synaptic plasticity, induce neuron regeneration, inhibit its apoptosis, and result in ethological and morphological recov-ery.

OBJECTIVE: To evaluate the effects of the therapy mainly for strengthening healthy energy to promote blood circulation in treating diabetic patients with gangrene. METHODS: A series of 112 diabetic patients with gangrene were investigated before and after treatment in the changes of wounds, clinical symptoms and quality of life. RESULTS: Fifty-eight cases were cured, 12 cases showed response, 36 cases improved, and 6 cases failure of treatment. The total obvious effect rate was 62.5% (70/112) and the amputation rate was 8.9% (10/112). The 104 diabetic cases of three-stage gangrene were classified into grade I, II and III. The total effect rates of the diabetic cases of grade I, II and III were 83.3% (30/36), 55.6% (35/63) and 20% (1/5), and the amputation rates were 0%, 12.7% (8/63), and 40% (2/5) respectively. After the treatment, the clinical symptoms, gangrene number, gangrene area and gangrene depth were obviously improved (P<0.05), and the quality of life was obviously improved (P<0.01), especially in physical condition, emotional well-being and therapeutic effects on patients (P<0.05). CONCLUSION: Strengthening healthy energy to promote blood circulation is effective in treating diabetic patients with gangrene.

Objective To investigate the effect of exercise preconditioning on serum level of tumor necrosis factor α (TNF-α), interleukin (IL) -1β and IL-6 in rats after cerebral ischemia-reperfusion (I/R). Methods 24 male Sprague-Dawley rats were randomly divided into exercise preconditioning group (n=8), model group (n=8) and sham group (n=8). The middle cerebral arteries were occluded for 120 min and re-perfused. All the rats were evaluated with neurological deficit score 2 hours, 24 hours after I/R. The serum levels of TNF-α, IL-1β and IL-6 was detected with enzyme-linked immunosorbent, and the pathology was observed with HE staining 24 hours after I/R. Results The neurological deficit score decreased in the exercise preconditioning group compared with that in the model group, as well as the serum TNF-α, IL-1β and IL-6 (P<0.05) 24 hours after I/R. The pathological damage and interstitial edema alleviated in cerebral ischemia cortical, and the degeneration and necrosis of the neurons in the ischemic area significantly reduced in the exercise preconditioning group. Conclusion Exercise preconditioning may inhibit inflammatory response in I/R rats to protect neurological function from impairment.

Objective To study the effect of cluster needling of scalp acupuncture combined with rehabilitation on neurological function and expression of basic fibroblast growth factor (bFGF) and angiostatin (AS) in rats after focal cerebral ischemia. Methods 90 male Sprague-Dawley rats were randomly divided into sham operation group, model group, acupuncture treatment group, rehabilitation treatment group and acupuncture and rehabilitation treatment group, each group was further divided into 3 days, 7 days and 14 days subgroups (n=6). Permanent cerebral ischemia rat model was established according to Longa's method. The model group and the sham operation group accepted no treatment, the acupuncture treatment group was treated by cluster needling of scalp acupuncture, the rehabilitation treatment group received the treadmill training, the acupuncture and rehabilitation treatment group was treated by acupuncture and rehabilitation therapy. 3 days, 7 days, 14 days after operation, the neural function was evaluated with the modified Neurological Severity Score (mNSS), the expression levels of bFGF and AS proteins were detected by Western blotting. Results Compared with the model group, the acupuncture treatment group and the rehabilitation treatment group, mNSS decreased, the expression of bFGF protein increased, and the expression of AS protein decreased in the acupuncture and rehabilitation treatment group 3 days, 7 days, 14 days after operation (P<0.05). Conclusion Acupuncture and rehabilitation therapy can reduce the neurological function defect in rats with focal cerebral ischemia, which may be related to the upregulation of bFGF protein expression and down-regulation of AS protein expression.

Objective To investigate the effect of electro-acupuncture pretreatment on content of interleukin (IL)-1βand IL-6 in serum and ischemic penumbra, and apoptosis in ischemic penumbra in rats after cerebral ischemia-reperfusion injury. Methods Thirty-six male Sprague-Dawley rats were randomly divided into sham group (n=12), model group (n=12), and electro-acupuncture pretreatment group (n=12). The middle cerebral arteries were occluded for 120 minutes and reperfused. Twenty-four hours after reperfusion, the level of IL-1βand IL-6 in serum and brain tissue was detected with enzyme-linked immunosorbent, and apoptosis of ischemic penumbra was detected with TU-NEL. Results The content of IL-1βand IL-6 in the serum and brain tissue, and the number of TUNEL-positive cells decreased in the elec-tro-acupuncture pretreatment group compared with that in the model group (P<0.01). Conclusion Electro-acupuncture pretreatment may in-hibit inflammatory response and apoptosis in cerebral ischemia-reperfusion injury.

ObjectiveTo investigate the clinical efficacy of acupuncture plus keritherapy for knee osteoarthritis.MethodForty patients with knee osteoarthritis meeting the inclusion criteria were allocated, using a random number table, to treatment and control groups, 20 cases each. The treatment group received acupuncture plus keritherapy and the control group, acupuncture. Treatment was given for four weeks. The clinical therapeutic effects were evaluated using the Visual Analogous Scale (VAS) and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) in the two groups.ResultAfter four weeks of treatment,the VAS score and the WOMAC score decreased significantly in the treatment group of patients compared with the control group; there was a statistically significantdifference (P<0.05).ConclusionAcupuncture plus keritherapy can relieve pain around the knee and improve knee dysfunction in patients with knee osteoarthritis.
