Objective To study the application of native pelvis and ureter in kidney transplantation. Methods Between 1977 and 2001, 1 364 kidney transplantations were performed in our institution. 18 cases of ureteral complication after kidney transplantation were treated with native pelvis and ureter. The mean age of the patients was 42 years. In 10 patients with urine leakage, 3 cases underwent pyeloureterostomy using native ureter, 2 cases ureteroureterostomy using native ureter and 5 cases pyelopyelostomy using native pelvis. Five cases due to short ureter underwent ureteroureterostomy using native ureter. Three cases of ureteral stenosis were subjected to ureteroureterostomy using native ureter.Results Two grafts were rejected. Sixteen patients developed a normal function of kidney postoperatively (follow up: 3 months to 8 years). Conclusion Application of native pelvis and ureter might be a therapy of choice when secondary reconstruction by re-ureteroneocystostomy is not possible.

Small and medium-sized enterprises (SMEs) are important components in Chinese medicine industry. However, the lack of big brand is becoming an urgent problem which is critical to the survival of SMEs. This article discusses the concept and traits of Chinese medicine of big brand, from clinical, scientific and market value three aspects. Guided by market value, highlighting clinical value, aiming at the scientific value improvement of big brand cultivation, we put forward the key points in cultivation, aiming at obtaining branded Chinese medicine with widely recognized efficacy, good quality control system and mechanism well explained and meanwhile which can bring innovation improvement to theory of Chinese medicine. According to the characters of SMEs, we hold a view that to build multidisciplinary research union could be considered as basic path, and then, from top-level design, skill upgrading and application three stages to probe the implementation strategy.

Acrylonitrile is most commonly used aliphatic nitrile compounds characterized by the structural formula R-C=N and used mossy to make acrylic fibers, plastics, synthetic rubber, and wall coverings. In recent, because of its extensive usage and the rapid expansion of the chemical industry, many poisonings have been reported and many studies on its health effects have been performed. Acute toxicity resembles cyanide poisoning and results mainly in effects on the nervous system. High exposure also can cause temporary damage to red blood cells and the liver and can cause lead to death. Because long-term occupational exposure to the acrylonitrile has been with cancer in humans, the U.S EPA classifies acrylonitrile as probable carcinogen. For this reason, The federal government has developed regulations and advisories to protect individuals firm the potential health effects of acylonitrile in the environment, but there are few studies, case reports and regulations of the government in our country. We experienced acute poisoning caused by acrylonitrile inhalation that occurred in an industrial accident. So, we report this case with literature reveiw.

Objective To evaluate catheter thrombectomy,mechanical thromboaspiration and catheter-directed thrombolysis for the treatment of deep venous thrombosis.Methods From January 2015 to February 2016,60 patients with acute deep vein thrombosis were placed the inferior vena cava filter from contralateral femoral vein or right internal jugular vein.A 5 F pigtail catheter was led to the ipsilateral deep vein,bolus urokinase was given and catheter thrombectomy was undertaken and thromboaspiration was carried out using 10-12 F catheter,then through catheter continuous infusion of urokinase.Results 45 cases were cured,8 cases were significantly improved,5 cases were improved,2 cases were judged as ineffective,the effective rate was 96.6％.Before thrombolysis the thigh circumference difference between affected limb and the contralateral limb was (3.6 ± 1.9)cm (P ＜0.05),calf circumference difference was (4.6 ±2.1)cm (P ＜ 0.05);The difference between the affected limb and contralateral thigh circumferences was (0.19±0.90) cm (P ＞ 0.05),calf circumference difference was (0.5 ± 1.0) cm (P ＞ 0.05).Conclusions Catheter thrombectomy,thromboaspiration and catheter-directed thrombolysis for deep venous thrombosis is safe and effective.

Objective To provide a clinical anatomic basis for the bi-pedicled gastrocnemius myocuta- neous flap which is to be used to repair defects of the Achilles tendon and posterior skin of the ankle.Methods In anatomic study,out of 30 cadaver specimens,bi-pedicled V-Y gastrocnemius myoeutaneous flaps were harvested to measure the downward sliding lengths of the flap when the knee was at flexion of different degrees.In clinic,12 patients with the Achilles tendon and posterior ankle skin defects were repaired with the bi-pedicled gastrocnemius myocutaneous flaps.The areas of composite defects ranged from 10 cm?6 cm to 6 cm?4 cm.They were followed up for four months to 12 years.Results The maximal sliding length of the flap reached (9.2?0.9)cm when the knee was at flexion of 90?.All the clinical flaps survived and ambulation of the patients recovered.The dorsiflexion and plantarflexion of the ankles reached 11.0??1.4?and 35.0??4.6?respectively.Conclusion This flap is suitable for one-stage repair of composite Achilles tendon defects.

The fermentation conditions of lipase production by Geotrichum candidum Y162 were optimized. Initially, the most suitable carbon olive oil, nitrogen source soybean flour and NH4Cl, salt BaCl2 and MgCl2 were selected according to single factorial experiments respectively. Based on the result, screening methodology Plackett-Burman design was used to evaluate the effects of twelve factors related to lipase production and three statistically significant factors olive oil, BaCl2 and NH4Cl were selected. The path of steepest ascent was used to approach the optimal region of lipase production subsequently. Then, the optimal combined concentration for maximum enzyme activity were further optimized by response surface methodology and determined as follows: olive oil 2.35%, BaCl2 0.36%,and NH4Cl 4.69%.The optimization of culture conditions of G.candidum Y162 led to a 2.25-fold increase in lipase production relative to initial result 14.16 U/ml, which indicate that single factor in combination with response surface methodology is an effective method for optimization of lipase production conditions by G.candidum Y162.

Objective To discuss the diagnostic value of dynamic contrast-enhanced MRI in differentiating vertebral metastatic tumors from benign deseases after studying the early changes of signal intensity.Methods Twenty patients were scanned by dynamic contrast-enhanced MRI.The parameters of signal intensity were measured and calculated,and time-intensity cures(TICs)were drawn.Then,they were compared with those of normal verte- braes,the characteristics were analyzed.Results The parameters of vertebral metastatic tumors:peak signal intensi- ty,signal intensity minimum signal intensity of post-peak,peak slope,initial ratio of enhancement,maximum ratio of enhancement was respectively(50.61?11.38),(46.75?10.23),(0.73?0.12),(0.33?0.08),(1.03?0.31); that of normal vertebraes was respectively(40.53?12.12),(34.72?14.06),(0.31?0.11),(-0.25?0.05), (0.69?0.28);and ten normal cases showed negative in initial percent of enhancement,but only two abnormal ver- tebraes showed that.All of the above had significant statistical difference.Four types of TICs were concluded:early rapid rise and early rapid descent followed by steady phase(type A),persistently rise(type B),rise phase followed by steady phase(type C),rise phase followed by rapid descent phase(type D).TICs of abnormal vertebraes were respec- tively 6,5,5,5 cases;types of normal vertebraes were mainly type C,15 cases.Type A and type B and the type with the characteristic of early rapid descent phase were features of abnormal vertebraes;type C was the feature of normal ones.Conclusions Dynamic contrast-enhanced MRI could quantitatively show the characteristics of early changes of signal intensity of vertebral metastatic tumors,which were significant statistically different from those of normal ver- tebraes.Dynamic contrast-enhanced MRI was worth performing in the early diagnosis of vertebral metastatic tu- mors.
