Objective To improve a HPLOUV method for the determination of Tramadol hydrochlo-ride in human plasma. Method Alkalinized samples of plasma were extracted with dichloromethane. Tramadol and internai standard were analyzed on Elite C18 column (200mm?5.0mm, 5?m) with a acetoni-trile-phsphate buffer (pH6.5) (74:26, v/v) mobile phase and detedted at 220nm. Results The Calibra-tion plots in human plasma were linear (r=0.9984, n =5) from 10 to 800 ng/ml. The limit of detection was 10 ng/ml. For 20, 100, 400 ng/ml check samples, intra-run precisions (RSD) were 3.81% -5.44% and inter-run preceisions (RSD) were 3.95% -4.41% , respectively. The average recoveries were 89% , 96% and 92% for the low, middle and high check samples, respectively. Conclusion The improved ana-lytical method for Tramadol hydrochloride was found to be sensitive, simple and rapid, suitable for applica-tion in forensic toxicological analysis and routine determination of numerous samples.

Objective To evaluate the feasibility and safety of transjugular liver biopsy (TJLB) by using LABS 100 liver access and biopsy set (Cook Inc, bloomington, IN, USA). Methods During the period from June 2014 to Sep. 2014, a total of twelve patients received TJLB at authors’ hospital. The clinical data were retrospectively analyzed, and the indications, number of puncturing times, technical success rate, complications, sufficient amount of specimen, etc. were summarized. Results Technical success of TJLB was achieved in all patients, and no procedure- related complications occurred. The mean number of puncturing was 2.8 times, and sufficient amount of specimen for histological examination was obtained in all cases. Conclusion This preliminary result indicates that transjugular liver biopsy with the use of LABS 100 liver access and biopsy set is clinically safe and feasible.

A novel method was developed for the direct analysis of testosterone, androstenedione, methyltestosterone and methenolone in serum samples by fully automated online turbulent flow solid phase extraction coupled with high performance liquid chromatography-tandem mass spectrometry. An aliquot of 50 μL serum sample was preconcentrated directly on a Turboflow SPE column after centrifugation. Turboflow SPE C18-P could be used to remove serum matrix effectively. The optimum loading flow rate and elution time were 4. 0 mL/min and 1. 0 min, respectively. The linearity ranges were from 1. 0 μg/L to 100. 0 μg/L for four target compounds. The method limits of detection ( LODs) were in the range of 0. 2-0. 3 μg/L. The relative standard deviations (RSDs) ranged from 2. 9% to 14. 1% (n=5). The time for one sample analysis including extraction, separation and determination was 32 min. The proposed method has been successfully applied for the analysis of serum samples.

Objective To investigate the resistance rate of Pseudomonas aeruginosa to several commonly used antibiotics,as well as the prevalence status of three species of integrons in multi-drug resistant Pseudomonas aeruginosa from 2005 to 2006 in our hospital,and to identify the genetic structure of class Ⅰ integron in in our hospital.Methods Drug resistance slip method was applied to detecting the resistant rates of 100 isolates of Pseudomonas aeruginosa to ciprofloxacin,cefotaxime,gentamicin and imipenem.Boiling method was adopted to abstract DNA template of 100 isolates of Pseudomonas aeruginosa,and PCR assay adopted to identify the prevalence rate of three species of integrons and class Ⅰ integron structure.Results The resistant rates of 100 isolates of Pseudomonas aeruginosa to ciprofloxacin,cefotaxime,gentamicin,cefoxitin,tobramycin and imipenem were 32%,45%,82%,37%,39% and 43% respectively.The prevalence rates of three species of integrons was as follows:class Ⅰ 53%,Ⅱ 21% and Ⅲ 5%.Sequence analysis displayed there existed box gene dfrA17 and aadA2 in variable region of class Ⅰ integron.Conclusion The resistant rates of Pseudomonas aeruginosa to four drugs are elevated,especially to gentamycin.Multi-drug resistance may be partly due to prevalence of class Ⅰ integron.

6 cases(2 males to 4 females) who have received mandibula reconstruction with free vascularized fibular flaps in our hospital were studied retrospectively.The average length of the fibula grafts was 8.0 cm(range from 7.0 to 14 cm). 3 cases received primary insertion of osteointegrated dental implants into the free fibula flap. The mean follow-up of six cases of patients was 3 months to 1 year. The success rate was 100%. All patients spoke clearly. 4 patients could eat normally, the other two could eat soft food. 5/6 of patients with the recovery of facial appearance was satisfied. All patients were able to walk normally. No ankle unstability was reported. Vascularized free fibula flap is confirmed to be one of the optimal methods for mandible reconstruction by our study.

Objective To study the clinical features and angiographic findings of moyamoya disease (MMD) as well as their relationship. Methods A total of 22 MMD patients received routine digital substraction angiography (DSA). The clinical manifestations and angiographic findings were analyzed. Results Clinical manifestations varied and each patient often had multiple symptoms, including cerebral infarction in 9 patients with an average age of 23.6 (13-39 years) and cerebral hemorrhage in 7 patients with an average age of 31.2 (28-46 years). Angiographic examination found that all the diseased sides showed MMD blood vessels. The patients who received encephalo-myo-arterio-synangiosis (EMAS) had better prognosis than those without receiving the treatment. Conclusion Cerebral infarction is frequent in children and adolescents with MMD, whereas cerebral hemorrhage is common in adults. DSA is a golden criterion for diagnosing MMD. Surgical treatment, EMAS blood supply reconstruction in particular, should be prescribed.

Dendrobium officinale is a kind of precious Chinese herbal medicine, which has good effects on the anti-aging, antineoplastic, and blood glucose reducing treatment. It has been listed in the top of “Nine Magic Herbs”, with significant cultural features of traditional Chinese medicine (TCM). Planting, processing, and cultural base construction of Dendrobium officinale in Hunan Province have obtained great achievements. Further combination of Dendrobium officinale with TCM culture will develop a series portable and convenient tourism products with the features of wide taking habits and large intended population. The planting of Dendrobium officinale should be integrated with ecofallow organically; the construction of science museums about Dendrobium officinale should be improved; the modern view on health maintenance “Health maintenance should focus on Yin nourishment” should be included in TCM cultural tourism in Hunan Province. All of these can improve the potential of tourism product development, meet the living requirements of modern people, and drive the development of tourist industry in Hunan Province.

Objective To explore the effect of continuing nursing on the rehabilitation of patients with benign prostatic hyperplasia (BPH) after transurethral resection of prostate (TURP).Methods Toally 128 BPH patients after TURP in our hospital from May 2015 to May 2016 were evenly divided into control group and observation group by random digit table.The patients in the control group were normally guided at discharge and those in the observation group the continuing nursing was done by telephone,WeChat,QQ or family visits for 6 weeks after discharge besides normal guidance.The two groups were compared in terms of self-care ability,treatment compliance,complications and quality of life.Results After the intervention,the scores on health knowledge,self-care ability,self-care responsibility,self-care concept,self-care skills dimension of the observation group were significantly higher than those of the control group.The treatment compliance was significantly higher than that of the control group and the incidences of complications,including pain,hematuria,urinary intontinerce and retentron and infection,constipation were significantly lower than those of the control group.The scores on quality of life,physical function,role function,cognitive function,emotional function and social function score were significantly higher than those in the control group (all P＜0.05).Conclusion The continuing nursing after surgical treatment of benign prostatic hyperplasia patients can be effective in the improvements of patient's self-care ability,establishment of healthy life behavior,reduction of complications,promotion of their rehabilitation and ultimately the improvement of their quality of life.
