Objective To investigate whether there existed a healthy obese subtype.Methods A total of 116 healthy subjects were recruited.They were divided into 3 groups according to BMI and metabolic disorders:40 cases of normal weight and metabolic normality (NMN),36 cases of obesity and metabolic normality (OMN) and 40 cases of obesity and metabolic abnormality (OMA).Anthropometic parameters as height,weight,waist circumference,hip circumference and blood pressure was recorded.Blood glucose,lipids,insulin,high-sensitivity C-reactive protein (hs-CRP) was detected.Body fat distribution was detected by dual-energy X-ray absorptiometry (DXA).Serum von Willebrand factor (vWF),a marker of endothelial dysfunction,were detected by ELISA.Results Both serum vWF levels in OMN group [(733.6±86.2)U/L] and OMA group[(809.2 ±46.3)U/L] are higher than that in NMN group [(466.9 ±65.3)U/L,P ＜0.05] with serum vWF level in OMA group is higher than in OMN group (P ＜ 0.05).Among android fat mass percentage (AFM％),BMI,waist height ratio,waist circumference,hs-CRP,weight,hip circumference and trunk fat mass,AFM％,BMI and hs-CRP are main influencing factors of vWF.Conclusions Endothelial dysfunction existed in obese adults regardless of their metabolic status.There is no healthy obese subtype.AFM％,BMI and hs-CRP are the main influencing factors of endothelial dysfunction.

Objective To investigate the clinical characteristics,surgical treatment and outcome for patients with duodenal stromal tumor.Methods Data of 40 patients with stromal tumor of duodenum were reviewed retrospectively.Results All patients received resection including local resection in 14 cases,segmental resection of the duodenum in 17 cases,and pancreaticoduodenectomy in 9 cases.38 cases were followed-up,and two were lost.The median follow-up was 59 months (range 3-240 mos).The 1,3,and 5-year overall survival rates were 92％,76％ and 68％,respectively.No recurrence was found in very-low-risk tumor (n =1) and low-risk turmors (n =4).The 1,3,and 5-year overall survival rates for intermediate-risk tumors were 95％,80％ and 70％,respectively;and those were 69 ％,31％,and 0 for high-risk tumors,respectively.14 of 33 cases (42％) suffered from recurrence after radical resection for intermediate or high-risk tumors.33 postoperative cases received treatment with Imatinib (Glivec) for more than one year,and one case developed recurrence at 2.5 years after operation.4 patients with synchronous liver metastasis received palliative resection and Imatinib,and two survived more than 1 year.Conclusion Surgery is the first choice for duodenal stromal tumor,and Imatinib should be administered for high-risk disease after surgery.

Coptis chinensis is widely used as Chinese medicine herbs and serious soil problems occur after continual cultivation of this medicinal plant. In the preset experiment, fibrous root extract of C. chinensis (REC) was added into soil to study the effect of REC on microbes and enzyme activity in soil. The results showed that both bacteria and actinomycetes decreased by about 2 times in contrast to fungi, which increased by about 3 folds. Phosphorus bacteria, potassium bacteria, azotobacter, ammonia bacteria, and nitrifying bacteria were also reduced significantly by REC, suggesting the inhibition of nitrogen biofixation and supply, mobilization of phosphorus and potassium, ad plant growth promotion as REC added into soil. There were multiple influences of REC on soil enzyme activities. Invertase activity was stimulated, while urease was inhibited and dehydrogenase unchanged by REC, indicating the interference of biochemical reactions in soil. In addition, type and total content of phosphorus lipid fatty acids (PLFAs) , the signature of microbes, decreased while the ratio of bacterium to fungus PLFAs increased as REC increased in soil, which suggested that fungi increased relatively with bacteria decreased thereby leading to easy occurrence of crop fungus diseases following cultivation of C. chinensis. The decrease in diversity and evenness indexes of microbial community in soil by REC indicated soil ecosystem deterioration and reduction of microbial groups and densities in soil. Therefore, allelopathic chemicals released from the roots of C. chinensis could change microbial community structure and resulted in serious soil problems by continual cropping of this medicinal plant.

ObjectiveTo explore the effect of musicotherapy on agitation behaviors in patients with aged dementia (AD).Methods22 AD patients were treated with different musicotherapies, and examined with Mini-Mental State Examination (MMSE), Cohen-Mansfield Agitation Inventory (CMAI) and self made sociality psychological inventory before and after treatment.ResultsAfter musicotherapy, the incidence rate of agitation behaviors of AD patients decreased significantly ( P<0.001). The incidence rates of agitation behaviors among patients with low, middle and high MMSE scores were significantly different ( P<0.001). After musicotherapy, both depressions of patients' cognitive function and scores of agitation behaviors were significant different compared with that before treatment (P<0.01). Effectual rates of musicotherapy on sociality psychological emotion, communication, language and intercourse of this group patients were 86.36%, 90.91%, 72.73% and 77.27%, respectively.ConclusionMusicotherapy can effectively alleviate the symptoms of agitation behaviors in AD patients.

Objective:To determine the diagnosis, treatment, and pathogenesis of ketamine-associated cystitis.
Methods:Clinical data from 3 patients with ketamine-associated cystitis were analyzed retrospectively and discussed in light of relevant literature.
Results:In the 3 cases, 2 presented severe lower urinary tract symptoms, including frequency, urgency, dysuria, urge incontinence, and painful haematuria. Urinalysis and urine culture were negative. Imaging examination demonstrated thickening of the bladder wall and a small capacity. Inflammatory changes in the bladder mucosa were observed by cystoscopy and biopsies. After cessation of ketamine use, with the addition of steroids or hydrodistension, the symptoms in the 3 patients improved. The symptoms recurred in 2 patients, as 1 was exposed to ketamine again and 1 had severe bladder contraction after for 3-4 month follow-up.
Conclusion:Ketamine-associated cystitis is a new urinary system inlfammatory damage. Its etiology and treatment methods are not clear. early abstinence from ketamine use and early treatment are crucial for patients with ketamine-associated cystitis to avoid irreversible damage.
