Objective To investigate the clinical efficacy of total parathyroidectomy and autologous transplantation(PTX+ AT) for treating secondary hyperparathyroidism(SHPT) in the patients with uremic maintenance hemodialysis and postoperative calcium supplementation.Methods The clinical data in 57 patients with SHPT treated with PTX+ AT in the urology department of the First Affiliated Hospital of Nanjing Medical University from March 2015 to August 2015 were retrospectively analyzed.The changes of serum intact parathyroid hormone(iPTH),calcium and clinical symptoms were observed before and after operation.Results Serum iPTH levels at different time points of immediately after operation,postoperative 20 min,2 d,4 d were(288.57 ±194.71),(185.00±99.28),(83.83 ± 58.26),(17.91± 15.60) pg/mL respectively,which were significantly decreased compared with (2395.80 ± 829.04) pg/mL before operation (P＜ 0.05);blood calcium at postoperative 4,8,24,72 h was (2.34 ± 0.32),(2.16±0.37),(2.16±0.27),(2.25±0.25) mmol/L respectively,which were significantly decreased compared with(2.61±0.25)mmol/L before operation(P＜0.05);the symptoms such as bone pain,skin itching and so on were significantly improved.Conclusion PTX+AT can effectively treat uremic SHPT,and postoperative timely calcium supplementation can reduce the occurrence of hypocalcemia.

In order to discover the steroid biotransformation ability of filamentous fungus Aspergillus niger TCCC41650, we studied the fermentation of 4-androstene-3,17-dione with A. niger TCCC41650. The transformation product was purified, crystallized and determined as 16β-hydroxy-androst-4-ene-3,17-dione by X-ray single crystal diffraction method. The best fermentation condition was found to be pH 6.0, ethanol amount 2% with a substrate concentration of 1 per thousand, the transformation rate is 85.81% after 72 h. Based on the best of our knowledge, 16β-hydroxylation rarely occurs in microbial transformations of steroid. This study laid the foundation for the research of 16β-hydroxylation steroids

Objective To study the method and effect of lateral arm free flap in reconstruction of severe atresic eye socket.Methods Forteen cases of severe atresic eye socket,from June,2011 to June,2013,were repaired by lateral arm free flap.The flaps were designed and harvested as drop shape with size about 6 cm × 10 cm and then were removed epidermis except distal 6 cm × 6 cm area which were transferred to orbit for eye socket reconstruction.The remaining fascia and dermis were filled to augment temporal defect.Superficial temporal artery was anastomosed with posterior branch of radial collateral artery in 14 cases and superficial temporal vein was anstomosed with radial collateral vein in 11 cases,with middle temporal vein in 3 cases.Results All 14 cases lateral arm free flaps survived with no donor site morbidity.Followed up for 1 year to 3 years,artificial eye could be fitted satisfactorily and temporal contour improved.Conclusion Lateral arm free flap is a recommendable option for severe atresic eye socket reconstruction because of concealed donor site scar,proper volume,matched vascular caliber and minor donor site morbidity.

Objective: To evaluate the effect and safety of continuous veno-venous hemofiltration(CVVH) in the treatment of multiple organ failure(MOF) in senile patients.Methods: Sixteen patients with multiple organ failure,aged over 80 years,were divided into a survival group,who lived more than 20 days,and a non-survival group,less than 20 days after CVVH,and observed for such clinical indexes as of renal function,K+and blood gas analysis,APACHEⅡ scores and complications.Results: After CVVH,eleven of the patients survived for over 20 days,with 1 case up to 3 years.CVVH effected a significant improvement in BUN,Scr,K+and blood gas as well as a marked reduction in complications.APACHE Ⅱ scores decreased significantly after CVVH in the survival group though not in the non-survival group,as compared with those before CVVH,which were significantly lower in the former than in the latter.Conclusion: CVVH is a safe,effective and well-tolerated method for the treatment of MOF in senile patients.Patients with higher APACHEⅡscores have a poor prognosis.

Objective To study the effects of H_2S on the visceral pain induced by colorectal dis- tention (CRD) and the expression of substance P (SP)in rats.Methods Forty Wistar rats were randomly divided into control group,normal saline(i,p.) group,low( 15?mol/kg),moderate (45?mol/kg) and high(75?mol/kg) dose of NaSH(i.p.) groups.All rats.except control group,were subjected to CRD for 25 seconds and their behavioral responses to CRD were assessed by measuring the abdominal with drawal reflex(AWR).The expression of SP in the ileocecal junction,colon,spinal cord of thoracic waist (T6-L5) and brain was detected by immunohistochemistry.Results The visceral pain induced by CRD produced a capacity-dependent increase of AWR score in normal saline group,and a dose-dependent reduction of AWR score in three of NaSH groups.There was no significant differences of SP expression in the ileocecal junction,colon,spinal cord of thoracic waist and thalamencepbalon between the normal saline group and the NaSH low dose group.However,the decreased SP expression in the NaSH moder- ate and high dose groups were observed in comparison to those in the normal saline group(P

Objective: To observe the expression of urokinase-type plasminogen activator receptor (uPAR) in human tongue squamous cell carcinoma Tca 8113 cells at different dosages of heat shock. Methods:The expression of uPAR protein in Tca 8113 cells was examined using immunohistochemical technique (IH) and flow cytometry (FCM) after the cells had been treated at 37,40,43 or 45 ℃ for 40 min. Results:The fluorescent intensity of uPAR protein of Tca 8113 cells treated at 37,40,43 and 45 ℃ was 11.36?0.06,9.98?0.12, 10.37?0.05 and 11.31?0.10 respectively.Conclusion:Heat shock can reduce the expression of the uPAR protein of Tca 8113 cells.
