Objective To assess the short-term outcome of percutaneous transluminal renal angioplasty (PTRA) and stents for renal artery stenosis. Methods Twenty-six patients (17 males and 9 females) were diagnosed as renal stenosis by renal angiography and underwent simultaneous or selective PTRA and/or renal stenting. Changes in vessel diameter and perioperative complications were recorded. The blood pressure level, prescription of pressure-lowering drugs and the serum creatine level before and after the operation were analyzed. Results Unilateral artery stenosis was found in all 26 cases. Ostial stenosis were found in 18 cases (69%) and non-ostial stenosis in 8 cases (31%). The degree of stenosis was 70%-99%. All the 26 cases received renal stenting and 11 of them also received PTRA. The mean lumen diameter increased from 2.0 mm to 6.0 mm. The renal function was improved in 2 cases with impaired renal function before operation. The blood pressure leveal decreased or returned to normal level after stenting in 20 cases (76.9%) out of all the 26 hypertension patients. The were no perioperative complications recorded. Conclusion PTRA and/or renal stenting are effective and safe in treating renal artery stenosis.

[ABSTRACT]OBJECTIVETo explore the efficacy and safety of localization for parathyroid glands with intravenous low dosage of methylene blue in thyroidectomy. METHODSWe retrospectively reviewed the clinical data of 41 patients who suffered from thyroid papillary carcinoma between Aug, 2014 and Jan, 2015 (9 males and 32 females, with a median age of 46 years). Thirty eight patients underwent primary thyroidectomy and 3 patients underwent second operation. A variety of thyroidectomy was performed in all patients, and who also underwent intravenous (3-4) mg/kg methylene blue in operation. RESULTSEighty four parathyroid glands were stained. Among 39 patients who's parathyroid glands were stained, the mean dyeing time was (31.27±9.41) min. Dyeing rates and dyeing time were not significantly different between 3 mg/kg group and 4 mg/kg group (t=0.24 and 0.20, all P>0.05). None of patients had the hypoparathyroidism problem such as peri-oral numbness, tingling, muscle aches and spasms. According to postoperative monitoring of parathyroid hormone, all of patients had no permanent hypofunction of the parathyroid gland. Neurotoxic effects and other serious side effects were not observed in all patients. CONCLUSIONIntravenous low-dose methylene blue in thyroidectomy is a safe, easy, and effective technique that facilitates rapid identification of parathyroid gland.

Objective To learn the prevalence and trends of Brucella disease in Ningxia, in order to provide scientific basis for effective control of the disease. Methods Data of Brucella cases reported through city network from 2004 to 2009 in Yinchuan city, Shizuishan city, Wuzhong city, Guyuan city and Zhongwei city of Ningxia were reviewed and retrospectively analyzed. The data included demographic characteristics, treatment conditions and medical history so on related information. Analytical indicators include reported incidence;with patients' gender, age, regional distribution, urban and rural distribution;become chronic and associated factors;distribution of the cases reporting unit and so on. Results From 2004 to 2009, Ningxia had reported 349 cases of Brucellosis, no deaths, the annual incidence rates reported were 0.017/10 million, 0.543/10 million, 0.151/101 (295/54);The proportion of 34- to 40-year-old age group was higher than other age groups(27.5%, 96/349);Occupational distribution of patients was mainly farmers and herdsmen(70.2% ,245/349), in regional distribution of the patients, the highest percentage was Wuzhong city(61.9%,216/349), followed by Yinchuan city(22.9%,80/349);The proportion of patients in rural areas(97.4% ,340/349) was higher than urban(2.6% ,9/349);the proportion of patients converted to chronic was 11.2% (39/349). With age, the chance of patients converted to chronic was in a decreasing trend(odds ratio was 0.966);cases reported by Centre for Disease Control and Prevention accounted for 74.8%(261/349), by hospital accounted for 25.2%(88/349). Conclusions The reported incidence of Brucellosis in Ningxia is in a rapid upward trend year by year, the patients is mainly young men, the rate of converted to chronic is higher and the ability of hospital in founding and reporting of the cases is weaker.Comprehensive measures should be taken to increase funding, strengthen monitoring, and continuously improve the level of awareness and diagnosis of medical personnel for further strengthen the prevention and control of Brucellosis.
