Objective To study the feature of bone metabolism in different phase of elder type 2 diabetic nephropathy (DN) patients.Methods One hundred and fifty elder type 2 DN patients (non-microalbuminuria group,microalbuminuria group,clinic proteinuria group,DN renal inadequacy group and DN uremia group,each group was 30 cases),60 elder non-DN patients in chronic renal failure (CRF) (non-DN renal inadequacy group and non-DN uremia group,each group was 30 cases) ,and 30 elder healthy people (control group) were selected to observe the changes of osteocalcin (OT),β -crosslaps,parathyroid hormone ( iPTH),alkaline phosphatase (AKP),serum calcium (Ca),serum phosphorus (P) and Ca × P.Results In non-microalbuminuria group,microalbuminuria group and clinic proteinuria group,OT and β -crosslaps levels were lower than those in control group,and the lowest in microalbuminunia group (P＜0.01).In DN renal inadequacy group and DN uremia group,OT and β -crosslaps levels were higher than those in control group(P＜0.01).In the phase of CRF,OT,β -crosslaps and iPTH had no statistic difference between DN patients and non-DN patients,but had linear correlation.Serum P level was higher in DN renal inadequacy group and DN uremia group than that in control group(P＜0.01).Either DN or non-DN,serum P had more influence to Ca × P than serum Ca.Conclusions In the different phase of elder type 2 DNpatients,the effect of bone metabolism is different because of the different injury of renal function.Bone metabolism in the different phase has respective feature and mechanism,with low turnover in the first and high turnover in the end.

BACKGROUND:The incidence of low serum level of vitamin D in patients undergoing hip arthroplasty and its impact has not been reported in China, indicating that it has not been brought to the forefront. OBJECTIVE:To determine the prevalence of low serum level of vitamin D in patients before total hip arthroplasty and its relationship with the hip function scores. METHODS:Forty-eight hips from 48 patients undergoing primary hip arthroplasty from July 2013 to August 2014 in the First Affiliated Hospital of Suzhou University were enrol ed. According to the serum level of vitamin D, patients were assigned to low-level (<20μg/L) and high-level (20≥μg/L) groups. The general information of patients, the hip function scores before and after replacement at the last fol ow-up in the two groups were observed and compared. The relationship between the serum level of vitamin D and the hip function scores before and after replacement was analyzed by multiple linear regression analysis. And the average fol ow-up was 12 months (11-14 months). RESULTS AND CONCLUSION:(1) The incidence of low vitamin D level was 82%(20 ng/mL serving as standard). (2) Compared with patients with high vitamin D level, patients with low level of vitamin D had lower preoperative Harris scores and Merle D′Aubigne-Postel score (P<0.05), and also at the last fol ow-up (P<0.05. (3) Based on the preoperative and postoperative Harris, the multiple linear regression analysis showed that there was a positive correlation between the level of vitamin D and Harris score both preoperatively and postoperatively (P<0.05). (4) These results suggest that there is a higher incidence of low level of vitamin D in patients undergoing arthroplasty, and hip function scores before and after replacement in patients with low level of vitamin D are lower than the high level patients. Moreover, there is a positive correlation between the level of vitamin D and the hip joint function scores. Therefore, it is advisable to supplement vitamin D and calcium preoperatively, and the level of vitamin D wil be helpful for disease assessment and prognosis.

Objective To evaluate the efficacy of low-dose and long-term clarithromycin in treatment of chronic rhinosinusitis with positive bacterial biofilms.Methods Seventy-seven patients with chronic rhinosinusitis and positive bacterial biofilms underwent functional endoscopic sinusitis surgery between January 2008 and December 2009 in department of otolaryngology of Jinhua Central Hospital.Fortytwo patients were treated with clarithromycin 250 mg/d orally for at least 3 months (trial group).At the end of 3 months patients received endoscopic examination,for patients with mucosal epithelialization the clarithromycin therapy was stopped; for those with mucosal edema,granulation or polyoid formations the clarithromycin treatment was continued,but no longer than 5 months.Thirty-five patients in control group were not given clarithromycin.All patients were assessed by visual analogue scale (VAS) and nasal endoscopic examination (Lund-kennedy score) 6 months after surgery,the results were compared between two groups.Results Two patients in the trial group did not complete the protocol.VAS score and Lundkennedy score in trial group were 8.0 ± 0.8 and 3.6 ± 1.3 at 6 month after surgery respectively,while those in the control group were 7.3 ± 0.7 and 4.5 ± 1.7,and the differences were of statistical significance (t =5.311 and-3.187,P ＜ 0.01).Conclusion Low-dose and long-term oral administration of clarithromycin has positive impact on the prognosis of bacterial biofilms positive patients with chronic rhinosinusitis.

Objective To investigate disorders in calcium and phosphorus metabolism and abnormity in parathyroid function and their related factors in maintenance hemodialysis(MHD)patients.Methods We collected serum Hb,SCr,BUN,calcium,phosphorus,iPTH,high sensitivity C-reactive protein(hs-CRP),albumin and calculated albumin-corrected Ca and Kt/V from 198 patients with MHD in Jing'an District Central Hospital,Shanghai from Jan.2009 to Dec.2010.The calcium and phosphorus metabolism and parathyroid function were evaluated according to the guidelines of bone metabolism and controlling of bone disease in Kidney Disease Outcome Quality Initiative(KDOQI)recommended by National Kidney Foundation of the United States.198 patients were classified into the standard group(150-300 ng/L),lower than the standard group(＜150 ng/L)and higher than the standard group(＞ 300 ng/L)according to serum iPTH levels.Results In the 198 cases,110 cases were normal in serum Ac-Ca(55.6％); 118 cases were normal in serum phosphorus (59.6％); 143 cases were normal in Ca × P(72.3％); 39 cases were normal in iPTH(19.7％).All four items up to the standard were 28 cases(14.1％)among 198 cases.However,132(66.7％)patients showed lower than 150 ng/L in serum iPTH.The average serum iPTH gradually decreased with age.The senior patients demonstrated the highest average serum Hs-CRP,the lowest average serum phosphorus and the lowest albumin.There were no statistical significance in sex,hemodialysis duration,diabetes,blood pressure,Hb,Bun,SCr,Ac-Ca and Kt/V among three groups.Conclusion The disorders in calcium and phosphorus metabolism and abnormity in parathyroid function is common in the MHD patients.We should pay attention to hypofunction of parathyroid gland in the patients with MHD,which may be related to aging,malnutrition and potential infection.These findings need further investigation.

Objective To study the short-term clinical efficacy and its possible mechanism of refractory hypertension(RH) treated by continuous veno-venous hemofiltration (CVVH) in maintenance hemodialysis (MHD) patients. Methods Thirty-four MHD patients with RH treated with CVVH enrolled in the treatment group,all these patients were treatment of 2 -3 times,each time 8 - 10 hours. Thirty MHD patients with wellcontroled blood pressure were recruited as control. Changes of blood pressure, dry weight, plasma levels of parathyroid hormone (PTH), renin ( RA), angiotensin Ⅰ , Ⅱ ( AT Ⅰ , AT Ⅱ ), aldosterone ( Ald ) were observed before and after hemodialysis. Results In the treatment group,compared with pre-treatment, the blood pressure decreased significantly with an effective rate of 64.7% and efficient rate of 100. 0%. Before treatment, plasma RA was ([1.10 ±0.25] μg/(L · h)and [0:78 ±0.26] μg/(L · h),AT Ⅰ was [0.89 ±0.21] μg/L and [ 0. 52 ± 0. 14 ] μg/L, AT Ⅱ was [ 177.68 ± 89.46 ] ng/L and [ 89. 25 ± 12. 84 ] ng/L, Ald was [72. 06 ± 11.47 ]ng/L and [ 48.92 ± 8. 65 ] ng/L, PTH was [ 306. 81 ± 69. 37 ] ng/L and [ 248.76 ± 134. 62 ] ng/L in the treatment and control group respectively. All the measurements in the treatment group were significantly higher than those in the control group (P ＜ 0. 05 ). In the treatment group, compared to pre-treatment, plasma RA significantly decreased ( [ 1.10 ± 0. 25 ]μg/ ( L · h) vs [ 0. 76 ± 0. 17 ] μg/( L · h ), as well as AT Ⅰ ( [ 0. 89 ±0.21]μg/L vs [0.50 ±0.12] μg/L),ATⅡ([177.68±89.46]ng/L vs [ 87.13±14.22] ng/L),Ald ([72.06±11.47]ng/Lvs [ 46. 01± 9. 86 ] ng/L ) and PTH ( [ 306. 81 ±69.37]ng/L vs [ 186.53 ±32.93 ] ng/L) ( P ＜ 0. 05 ). However, there was no significant changes in the above mentioned measurements between before and after hemodialysis in the control group (P ＞ 0. 05). Conclusion CVVH may be an effective methods in the treatment of MHD patients with RH, and its antihypertensive mechanisms may be that CVVH can effectively remove the excess water in the body, and reduce plasma RA, AT Ⅰ , AT Ⅱ ,Ald and PTH levels.

Objective To assess the prognosis of patients with bladder neck (BN) involvement in radical prostatectomy specimens and compare it with patients with seminal vesicle invasion (SVI).Methods From January 2002 to December 2008,42 patients with prostate carcinoma who underwent radical prostatectomy were analyzed retrospectively.The mean age was 70.3 years (range 59-78 years).The patients were divided into two groups according to 2002 TNM system:pT4a group (bladder neck invasion) with 17 cases and pT3b group (unilateral or bilateral seminal vesicle invasion)with 25 cases.Postoperative outpatients were followed-up on a regular basis,two consecutive postoperative serums PSA greater than 0.2 μg/L defined as a biochemical recurrence.The postoperative follow-up to the time of biochemical recurrence or follow up to the deadline without biochemical recurrence were defined as biochemical recurrence free survival time.Results All patients were followed up for 50-122 months.The patients with BN involvement 17.6％ (3/17) had biochemical recurrence,whereas seminal vesicle invasion 24.0％ (6/25),there was no statistical significance between the two groups (P＞0.05).Conclusions Postoperative adjuvant therapies can improve the biochemical recurrence free survival.In this study,the prognosis of pT4a and pT3b group is similar.A conceivable down-staging of BN involvement in the TNM staging system should be considered.

ObjectiveTo observe the clinical characteristic and treatment response of the Gleason 5 + 5 prostate cancer and to summarize the prognostic factor of such patients. MethodsFrom January 2005 to May 2010,21 cases of Gleason 5 + 5 prostate cancer were enrolled in this study.The average age was 73 years and the pre-treatment PSA was 60.8 ng/ml.Six of the 21 cases had a PSA level ≤20 ng/ml.The maximal androgen deprivation therapy (ADT) in the form of castration and Casodex or fluctamide was carried out once the diagnosis was made.Bone metastasis was revealed in 16 cases.PSA levels were tested at the 4th month and then every 3 months after the castration.The observation endpoint was 6 months.Extracorporeal beam irradiation or the systemic chemotherapy was carried out if the PSA did not drop to a normal range after 6 months. ResultsIn the study group with initial PSA ＞ 20 ng/ml,the PSA did not drop to normal range in 5 cases; of which 4 had bone metastasis.With systemic chemotherapy,3 cases died within 1 year.Another case,with localized disease,received an extracorporeal beam irradiation and died within 1 year due to progression of the tumor.Among the remaining 10 cases sensitive to total androgen blockage,7 survived through the end of the study period.One case had PSA recurrence in month seven after the initial therapy and died at month 19.One case had PSA recurrence at month 22 and died at month 36.The patient had his PSA augmented at month 24 after total androgen blockage and the patient passed away 4 months later.Of the 6 cases who had an initial PSA ≤20 ng/ml 4 died within one year. ConclusionsGleason 5 +5 prostate cancer is relatively resistant to ADT with a worse prognosis,especially for the cases with a nadir PSA ＞4 ng/ml after 6 months’ ADT.The patients who had an initial PSA ≤20 ng/ml might have an unsatisfactory clinical outcome.

Objective To discuss the management of renal cell carcinoma(RCC) associated with von Hippel-Lindau(VHL) disease. Methods Clinical data were analyzed retrospectively from 28 ca-ses ( 16 males and 12 females, with a mean age of 45 years), of whom 15 had bilateral RCC and 13 had unilateral RCC. VHL germline mutation was analyzed in 25 cases. Nephron sparing surgery (NSS) or radical nephrectomy was performed in 24 cases. Results VHL germline mutations were detected in 25 cases including 14 asymptomatic patients. Among 29 solid renal tumors in 9 cases observed for a mean time of 44 months (range 12 to 86), the mean increase in tumor size was 0. 531 cm/year. There were 19(65.5%) tumors>3 cm at the end of follow-up but only 1 developed retroperitoneum lymph nodes metastasis. A total of 87 solid tumors were removed and 62 (71.3%) solid tumors were man-aged by NSS. Pathological results showed 86 clear cell carcinomas (73 Fuhrman Ⅰ and 12 Fuhrman Ⅱ ) and 1 calcified lesion. During mean follow-up of 50(5-237) months, local recurrence occurred in 4 cases treated with NSS; 26 patients were alive at the end of follow-up. Conclusions DNA testing might be helpful in the earlier detection of asymptomatic VHL patients. Most solid renal tumors in VHL disease grow slowly. The majority of the tumors >3 cm may still be indolent and do not metas-tasize during longer follow-up and can be observed. NSS is effective and safe for RCC in VHL disease.

Objective To study the histological classification,clinical stage,histological grade and prognosis of renal cell carcinoma by analyzing the records of the patients in Shanghai Renji hospital. Methods A consecutive series of 435 patients with renal cell carcinoma between 2003 and 2005derived from the renal cancer database were reviewed clinically and pathologically.The 1997 version of WHO histological classification for renal epithelial tumor,the 2002 version of AJCC clinical TNM staging system and the 1982 version of Fuhrmaffs system for nuclear grade were used.By survival analysis of 57 cases with advanced renal cell carcinoma using Kaplan-Meier method prognostic factors were confirmed using logrank test. Results Of a total 435 patients,cases were classified into 10(accounting for 2.4%of renal cell tumors)hereditary renal cancer in VHL disease,372(85.5%)clear cell renal cell carcinoma(CCRCC),13(3.0%)papillary renal cell carcinoma(PRCC),18(4.1%)chromophobe renal cell carcinoma(CRCC),4(0.9%)oncocytoma,4(0.9%)carcinoma of the collecting ducts of Bellini(CCDB),and 14(3.2%)renal cell carcinoma unclassified.There were 335(77%)patients undergone radical nephrectomy,74(17%)nephron sparing surgery and 26(6%)others,such as palliative nephrectomy.The patients with VHL disease come from 5 Chinese kindred and all had bilateral clear cell renal cell carcinomas and multifocal renal cysts.There were 7 paients of stage Ⅰ and 3 cases of stage Ⅱ and 6 cases of grade Ⅰ and 4 cases of grade Ⅱ.Genetic test revealed that all patients had VHL gene mutation.4 patients had recurrence while no evidence of local advance and distant metastasis were found during a mean of 28.6 months.Patients with chromophobe RCC are all of stage Ⅰ and 5 cases of grade Ⅰ and 13 cases of gradeⅡ.All patients are alive without recurrence or metastasis during a mean of 19.8 months.Collecting ducts RCC all presented with stage Ⅰ but grade Ⅲand with the median survival only 11.3 Months.Of clear cell and papillary RCC,260(67.6%),64(16.6%),32(8.3 %),29(7.5%)were stage Ⅰ,Ⅱ,Ⅲand Ⅳ,and of stage Ⅰ patients 147(38.2%),113(29.4%)were T1a and T1b respectively.124(32.2%),219(56.9%),40(10.4)and 2(0.5%)were grade Ⅰ,Ⅱ,Ⅲ,Ⅳ,respectively.Median survival of 57 advanced RCC is 16.0±1.3months,1-year survival is 55%,and 2-year survival is 31%,respectively.By using logrank test,clinical stage(＜0.01),tumor size(＜0.01),lymphadenopathy(＜0.01),metastasis(＜0.01)and tumor grade(＜0.01)were anatomical and histological prognostic factors for advanced RCC. Coneluslons Different RCC subtypes have different clinical course.The RCC patients in VHL disease have VHL gene mutation and the tumors are often multifocal,bilateral,clear cell type with a low stage and grade which often recurrence but without metastasis.Chromophobe RCC may have a favorable prognosis but collecting duct RCC poor prognosis.In anatomical and histological level,clinical stage,tumor size,lymphadenopathy,metastasis and tumor grade are prognostic factors of survival for advanced RCC.
