Objective:To observe the effect of Da Huang (Rheum Officinale) application at Shenque (CV 8) on constipation after operation for lumbar vertebral fracture. Methods:Seventy-four patients with constipation after operation for lumbar vertebral fracture were divided into an observation group and a control group by the random number table, 37 cases in each group. The two groups both received ordinary treatment (including healthcare guidance, emotional care, diet arrangement, and defecation nursing), while the observation group was additionally givenDa Huang (Rheum Officinale) application at Shenque (CV 8) for 6 h each day. The therapeutic efficacy was evaluated after successive 3-day treatment. Results:After 3-day treatment, it took significantly less time for the observation group to conduct the first flatulence and defecation than for the control group (P<0.05); the therapeutic efficacy of the observation group was significantly higher than that of the control group (P<0.01). Conclusion:Da Huang (Rheum Officinale) application at Shenque (CV 8) is effective in treating constipation after lumbar vertebral fracture operation, and it’s easy-to-operate and well accepted by patients, hence it’s proper to promote this method in clinic.

AIM: The present study is to investigate the inhibitory effect of the transfer of replication-defective retroviral recombinant plasmid encoding a wild-type P16 ink4a gene on the formation of restenosis after rabbit carotid arterial injury in vivo.METHODS:A replication-defective retroviral recombinant plasmid encoding wild-type gene P16 ink4a was constructed and the packaged high titer virus stock was obtained. It was transferred into the rabbit carotid arterial wall immediately after injury. The P16 ink4a mRNA expression in the arteries was examined by Northern blot and in situ hybridization. The effect of overexpression of the P16 ink4a gene on arterial intima hyperplasia was determined by pathophysiological method. RESULTS: The exogenous P16 ink4a could be effectively transferred into injured arterial wall by retroviral recombinant plasmid and the gene products could inhibit smooth muscle cells proliferation (11.80?3.54 vs 25.20?5.12,P

Objective To explore the status and influencing factors of surgical site infection (SSI)following lapa-roscopic surgery in patients in department of general surgery,so as to take effective measures to reduce SSI. Methods Active monitoring method was used to survey SSI among 401 patients undergoing laparoscopic surgery from January 1 ,2013 to December 31 ,2013,univariate analysis and multivariate analysis on risk factors for SSI were conducted.Results Of 401 investigated patients,12 (2.99%)developed SSI.Univariate analysis showed that risk factors for SSI in patients with laparoscopic surgery were elderly patients,emergency operation,infected wound,gastrointestinal tract operation,and grade Ⅳof ASA score (all P <0.05 ).Multivariate logistic regression analysis revealed that elderly patients (OR,5.02[95%CI ,1 .38 -30.25]),emergency operation (OR,4.37 [95%CI ,1 .96-28.55]),infected wound (OR,7.27[95%CI ,2.54-25.05]),and gastrointestinal tract operation (OR, 8.13 [95%CI ,1 .38 - 18.33 ])were high risk factors for SSI following laparoscopic surgery (all P < 0.05 ). Conclusion Thereare multiple factors influencing SSI after laparoscopic surgery,diversified prevention and control measures can effectively reduce the incidence of postoperative SSI.

ObjectiveTo investigate an optimal treatment of localized low flow type venous malformation located in the oral and maxillofacial region.MethodsFifty seven patients with localized low-flow venous malformation were treated by intralesional injection of PYM.The injections was repeated at an interval of 10 to 14 days,but not more than 3-5 sessions within a therapeutic period.If necessary,the secondary therapeutic period was performed 1 month later.The general and local adverse responses and the appearance improvement were recorded.The clinical outcomes and aesthetic effects were assessed with a follow-up of 1 to 3 years.ResultsAfter 3-8 injections,complete clinical resolutions were achieved in 52 patients.The deformity disappeared thoroughly.The surface skin and the appearance of lesions showed normal.4 patients received completed lesion control and showed nor mal skin or muco but a little hypertrophy tissue.One venous malformation reduced 2/3 volume after 8injections but improved slowly.The therapeutic time seemed to be related with the size of lesion.Diameter less than 3 cm could be usually cured within 1 treatment period.No ulcerations or scars were presented in injection regions.The function of nerves in oral and maxillofacial region remained normality in all patients.The systematic complication included transient pyrexia and poor appetite appeared in several cases.No allergy was found.No clinical recurrence was observed during the follow-up.ConclusionsTreatment of localized low-flow venous malformations in oral and maxillofacial region with PYM sclerotherapy reveals a high rate of complete clinical resolution,a fair cosmetic and function result,and does not damage facial nerves or form local scars.And it might be regard as an optimal therapeutic method to localized low-flow venous malformations.

Objective To investigate the function of the hypothalamic-pituitary-adrenal (HPA) axis in postmenopausal women with type 2 diabetes and visceral obesity. Methods Subjects were divided into three groups:control group(group C),type 2 diabetes mellitus with non-obesity group (group DM) and type 2 diabetes mellitus with visceral obesity group (group DM + OB). General clinical characteristics, morning blood cortisol concentrations and 24 h urine free cortisol of three groups were compared. Serum cortisol levels were also compared after 0.25 mg dexamethasone suppression test and followed by oral intake of 25 mg cortisone acetate. Results (1) There were no significant differences in basal cortisol levels, but after inhibition with dexamethasone the group DM + OB showed significantly higher cortisol level than that in the control group (P < 0.01). (2) Conversion of oral cortisone to plasma cortisol differed significantly between the group C (lower) and group DM + OB (P < 0.05). (3) Plasma LH and FSH concerntrations were significantly lower in group DM + OB compared with group C (P < 0.01). Conclusion In the postmenopausal women with type 2 diabetes mellitus, the negative feedback mechanism and hepatic 11β-HSD-1 activity were impaired, especially in those with visceral obesity.

Purpose To investigate the diagnosis,differential diagnosis and clinical manifestation of primary plasma cell leukemia (PPCL) and lymphoma with increased plasma cell.Methods Through clinical data and cell morphology,flow cytometry (FCM),immunofixation electrophoresis and immunohistochemistry of EliVision two-step examination were used to analyze 7 cases of PPCL and 3 cases of lymphoma with increased plasma cell.Results All patients with PPCL and lymphoma with increased plasma cell presented with anemia,thrombocytopenia,fever,liver and spleen and lymph node swelling.The proportion of plasma cells in peripheral blood morphology were larger than 20％,accompanied by morphological abnormality.FCM of peripheral blood showed all 7 cases of PPCL expressed CD38 and CD138,CD56 expression in the 2 cases and CD20 in the 2 cases.The light chain (Lamda,Kappa) showed a monoclonal restricted expression,which was consistent with the diagnosis of PPCL.CD19 and CD45 were weakly positive in 3 cases of lymphoma with increased plasma cell,CD38 and CD138 were positive,and no restricted expression was found in light chain IgL,wich belonging to the immunophenotypes of normal plasma cells.Of 3 cases of light chain (Ig) without restrictive expression,2 of them were angioimmunoblastic T-cell lymphoma (ATCL) and 1 case was CD30-positive sinusoidal large B-cell lymphoma (CD30 + SLBCL) that confirmed by lymph node biopsy and pathological examination.Conclusion The PPCL and lymphoma with increased plasma cell have the same clinical manifestations and similar morphological characteristics of blood cells.The diagnosis of PPCL should be combined with immunoelectrophoresis and FCM,and the diagnosis of lymphoma with increased plasma cell needs to be confirmed by histological examination of lymph nodes.

Objective To investigate the related factors of percutaneous balloon compression (PBC) for the treatment of trigeminal neuralgia complicating cerebrovascular disease in order to reduce the incidence of surgical complications. Methods The clinical data in patients with trigeminal neuralgia complicating cerebrovascular disease treated with PBC in the People's Hospital of Liaoning Province from December 2000 to December 2010 were analyzed retrospectively. The reasons for its occurrence were investigated. Results Of the 6 759 patients with trigeminal neuralgia who received PBC treatment, 10 (0. 15％ ) developed cerebrovascular disease,and 2 of them had arteriovenous fistula; 5 patients developed intracranial hemorrhage: 2 acute subdural hemorrhage, 2 intraventricular hemorrhage with subarachnoid hemorrhage, and 1 small amount of bleeding in brain stem; 1 patient developed internal carotid hemorrhage during the intraoperative puncture and the operation was stopped temporarily, and he was reoperated successfully after 2 weeks; 2 patients had cerebral infarction, they were all in the risk population of cerebrovascular disease, and 3 weeks after treatment, their disease conditions were improved. One of them left severe paralysis of limbs at discharge. Condusions The treatment of trigeminal neuralgia with PBC is safe and the incidence of cerebrovascular complications is lower. The surgical operations and blood pressure changes are the important causes of cerebrovascular complications.

Objective:To investigate the mental health status of plastic surgery patients.Methods:A total of 487 plastic surgery patients [4 males and 475 females, aged 17-66 (30±10) years)] from Jiangsu Provincial Hospital of Chinese Medicine were investigated by symptom checklist 90 (SCL-90).Results:In a sample of 479 cases, 111 were positive for SCL-90, accounting for 23.1%. Among non-reconstructive surgeries, 92 out of 439 cases were positive, representing 21.0%, while in reconstructive surgeries, 19 out of 40 cases were positive, amounting to 47.5%. The positive detection rate of SCL-90 in reconstructive surgeries was significantly higher than that in non-reconstructive surgeries (χ 2=21.20, P<0.05). Compared with the national norm, the overall mental health status of patients with plastic surgery and cosmetic surgery showed that the average scores of obsessive-compulsive state (1.91±0.43), anxiety (1.46±0.31), hostility (1.60±0.36), and terror (1.28±0.24) were statistically significant higher than the norm ( t=10.03, P<0.05; t=3.27, P<0.05; t=5.20, P<0.05; t=2.50, P<0.05). The average score of obsessive-compulsive state (2.11±0.54), interpersonal sensitivity (1.82±0.39), depression (1.68±0.50), hostility (1.74±0.45), terror (1.39±0.28), paranoia (1.49±0.34), and psychotic (1.35±0.28) in patients undergoing reconstructive surgeries were all higher than those without reconstructive surgeries ( t=2.97, P<0.05; t=2.10, P<0.05; t=2.18, P<0.05; t=2.18, P<0.05; t=2.80, P<0.05; t=2.20, P<0.05; t=2.10, P<0.05). Conclusions:The results of SCL-90 show that the mental health level of plastic surgery patients (especially repair surgery patients) is lower than that of the normal population, which suggests that we should pay attention to the psychological evaluation and care about the physical and mental health of these patients.
