Objective To investigate the causes,diagnosis and treatment of small intestine bleeding.Methods Sixty-eight cases of small intestine bleeding from January 2000 to June 2010 were retrospectively analyzed.Among all cases,4 underwent routine hemostatic treatment under colonoscopy,40treated with open surgery and 24 patients with laparoscopic therapy.Among them,57 cases underwent part resection for some small intestine,completely laparoscopic resection of diverticula was performed in 7patients.Results Neoplasms was the leading cause of small intestine bleeding,accounting for 48.5％ (33/68)in these patients,followed by small intestine diverticulum accounted for 29.4％ ( 20/68 ),intestinal infective diseases accounted for 14.7％ ( 10/68 ) and vascular disease accounted for 7.4％ ( 5/68 ).Conclusion The clinical manifestations of small intestinal bleeding showed no specific signs.Neoplasm,intestine diverticulum and intestinal infective diseases are the most common causes of small intestinal bleeding.Small intestinal bleeding can be diagnosed in intraoperative colonoscopy.Surgery is the most effective treatment for small intestinal bleeding.

Objective To investigate the changes of cerebral blood flow and the level of brain injury in a rat model of deep hypothermia low flow(DHLF).Methods Twelve SD rats aged 3 weeks were randomly divided into sham group and model group.Regional cerebral blood flow(rCBF)of all rats was measured continuously during the operation by laser Doppler flowmetry,and the changes of rCBF were measured before temperature decreased,when the temperature decreased to(21.0±0.5)℃,0-5 minutes,25-30 minutes,55-60 minutes,115-120 minutes during DHLF and 0-5 minutes after DHLF operation.Another 60 SD rats aged 3 weeks were randomly divided into sham group and model group.Six rats of each group were sacrificed at 1,6,24,72 hours and 7 days after DHLF operation to detect the pathological changes of the brain and the neuronal apoptosis by HE staining and TUNEL assay.The neurological deficit score(NDS)was recorded at 24,72 hours and 7 days after operation for evaluating the neurologic functional outcome.ResultsWhen the temperature was decreased to(21.0±0.5)℃,the levels of rCBF of sham group and model group were significantly decreased to(41.1±4.2)% and(40.7±3.4)% of the baseline value,and the rCBF level of model group was further decreased to(15.7±3.5)% of the baseline value 0-15 minutes during DHLF(P ＜ 0.01),with no obvious changes in all the time intervals during DHLF.Compared with the sham group,the scores of NDS of model group were significant lower at 24 and 72 hours after operation(P ＜ 0.05 or 0.01).Besides,a significant pathological change of the brain tissue and a increased percentage of TUNEL-positive staining cells were observed in model group at 6,24,72 hours and 7 days after operation(P ＜ 0.01).Conclusions Rat model of DHLF is an ideal and reliable model of brain injury,for it is similar to DHLF procedure of clinical cardiac operation.

Objective:To compare the clinical effecacy of artificial dermal regeneration matrix (as "artificial dermis" hereafter) and flap transfer in the treatment of soft tissue defects around interphalangeal joint.Methods:Through postoperative follow-up at outpatient clinic, a retrospective study was conducted on the clinical data of 60 patients who had soft tissue defects around the interphalangeal joints and received treatment in the Department of Hand Surgery, the Sixth Hospital of Ningbo from January 2018 to January 2022. According to applied surgical procedures, patients were divided into a flap transfer group (group A, n=30) and an artificial dermis group (group B, n=30). Group A included 19 males and 11 females aged 44.83 years ± 11.56 years including 5 patients with simple soft tissue defects, and 6 with soft tissue defects and fractures, 10 with soft tissue defects with tendon and (or) ligament injuries, 3 with soft tissue defects and vessel and (or) nerve injuries, and 6 with soft tissue defects and over 2 other types of compound injuries. The defect areas ranged from 2.5 cm×1.2 cm to 5.0 cm×1.6 cm. After emergency debridement and treatment for bone and tendon injuries, the patients in group A received transfers of free flap or transfers with adjacent digit flaps or island flaps. Postoperative functional exercise started from 1-6 weeks after surgery. Patients in group B included 17 males and 13 females, aged 44.70 years ± 11.20 years and there were 6 patients with simple soft tissue defects, 6 with soft tissue defects and fractures, 9 with soft tissue defects and tendon and (or) ligament injuries, 5 with soft tissue defects and vessel and (or) nerve injuries, and 4 with soft tissue defects and over 2 other types of compound injuries. The defect area ranged from 3.1 cm ×1.3 cm to 4.5 cm × 1.8 cm. Debridement and treatment of the bone and tendon injury in group B were the same as what in group A, but the patients in group B received artificial dermis coverage other than transfer of flap. After an artificial dermis had completely vascularised, a split-thickness skin graft was performed over the neo-dermis in the second phase surgery. Postoperative functional exercise started from 1-2 weeks after artificial dermis grafting surgery. The interval time of flap transfer or split-thickness skin grafting, survival rate of flap transfer or split-thickness skin grafting, Vancouver Scar Scale(VSS), TPD and total active movement(TAM) were compared between the 2 groups. The count data were analysed by Chi-square test. All measured data were analysed by independent sample t test or Mann-Whitney U test. P<0.05 indicates a statistically significant difference. Results:The interval time of flap transfer in group A and artificial dermis grafting in group B were 2.93 days ± 2.48 days and 19.87 days ± 3.35 days, respectively. There was a statistically significant difference between the 2 groups( P<0.05). All patients were entered in postoperative outpatient follow-up for 11-14 months(12.00 months ± 0.93 months). The appearance of flaps of some patients in group A was bloated with slightly limited digit movement. In group B, the digit movement was normal, without obvious scar hyperplasia in both of the recipient and donor sites. The survival rate of flap transfer or artificial dermis graft, TPD, VSS score and TAM score for group A and group B were 96.00% ± 9.32% and 98.17% ± 3.07%, respectively, 8.67 mm ± 2.01 mm and 9.50 mm ± 1.81 mm, 3.40 ± 1.07 and 3.17 ± 0.91 and 18.30 ± 1.97 and 18.93 ± 1.64, respectively. There were no significant differences between the 2 groups( P>0.05). Conclusion:In comparison with the transfer of flap, an artificial dermis is also effective and satisfactory in the treatment of soft tissue defects around the interphalangeal joint. Further large scale and multi-centre investigations are required.

Professor 's experience of acupuncture combined with medication for epilepsy is summarized, which is explained from epilepsy's etiology and pathogenesis, diagnosis and treatment of acupuncture and medication, respectively. Besides, the theoretical foundation and use instruction of acupuncture technique "-" for epilepsy are introduced. Professor highly values the adherence to etiology and pathogenesis, pays attention to syndrome differentiation and searches for the primary disease cause. He proposes the wind, phlegm, stasis and deficiency are the pathogenesis of epilepsy, and points out acupuncture could be applied during attack stage and remittent stage, but electroacupuncture should be used with caution. Regulating spirit is the key for treating epilepsy. The combination of acupuncture and medication could regulate the governor vessel and guide to the origin, which have significant curative effect.
