Objective To investigate the distribution characteristics of serum small dense low density lipoprotein-cholesterol (sdLDL-C) levels in healthy normolipidemia and hyperlipidemia and analyze the correlation between sdLDL-C and other serum lipids.Methods Totally 1012 normolipidemic subjects (18 93 years old,503 male,509 females) were grouped according to gender and age (18 -29,30 -69 and ≥70 years old).And 433 hyperlipidemic subjects (23 -90 years) were divided into the following 3 groups based on fasting triglyceride (TG) and low density lipoprotein-cholesterol (LDL-C)levels:hypertriglyceridemia (n =165 ),high-LDL-C ( n =129) and combined hyperlipidemia ( n =139 ).The sdLDL-C and other serum lipids were measured by Olympus AU2700 automatic analyzer.Analysis of Variance and Kruskal-Wallis H test was used for statistical analysis.Results The distribution of the sdLDL-C levels in normolipidemic subjects was near normal distribution.The sdLDL-C levels had differences in gender and age.In the 18 -29 and 30 -69 years old group,the mean values of sdLDL-C were significantly higher in males than in females [ (0.55 -0.21 ) mmol/L vs (0.47 ±0.22) mmol/L,t =2.212,P =0.028 and (0.66±0.28) mmol/L vs (0.62±0.25) mmol/L,t =2.121,P=0.034].In the ≥70 years old group,the difference of sdLDL-C levels in gender was not statistically significant [ male ( 0.54 ± 0.21 )mmol/L vs female (0.54 ± 0.22 ) mmol/L,t =0.022,P =0.982] ; the mean value was ( 0.54 ± 0.22 ) mmol/L The hyperlipidemic subjects had conspicuous higher levels of sdLDL-C compared with normolipidemia [ ( 1.25 ±0.44) mmol/L vs (0.60 ±0.26) mmol/L,t =29.306,P ＜0.001 ].Among all of groups,the combined hyperlipidemia group had the highest sdLDL-C level [ ( 1.52 ± 0.49) mmol/L,F =525.66,P ＜0.001 ] ; the hypertriglyceridemia group had the highest sdLDL-C/LDL -C level (0.47 ±0.12,F =287.93,P ＜0.001 ) and the high-LDL-C group had the highest level of non-sdLDL-C [LDL-C subtract sdLDL-C,(2.71 ± 0.52) mmol/L.F =336.32,P ＜ 0.001 ].The sdLDL-C showed a good positive correlation with TC,TG,LDL-C,ApoB and BMI ( rs =0.66,0.68,0.65,0.79 and 0.27,P ＜ 0.001 ),and negative correlation with HDL-C and ApoA1 ( rt =- 0.42 and - 0.37,P ＜ 0.001 ).Based on partial correlative analysis,sdLDL-C showed a different correlation with TG,LDL-C and TC ( r =0.42,0.28 and 0.15,P ＜ 0.001 ).Conclusions LDL-C and TG are the important factors influencing the sdLDL-C levels.However,TG has greater effect than LDL-C.The sdLDL-C is an appropriate and good index to evaluate the small dense low density lipoprotein (sdLDL) mass and the overall situation of lipid metabolism.In order to make full use of sdLDL in the clinical treatment and health assessment,it is necessary to establish sdLDL-C reference intervals through the survey of distribution of sdLDL-C levels in different geographic areas.

OBJECTIVETo assess the feasibility and safety of robot-assisted laparoscopic radical prostatectomy (RLRP) in the treatment of prostate cancer.

METHODSUsing the da Vinci robot surgical system, we performed RLRP for 34 patients with localized prostate cancer and analyzed the intraoperative and follow-up data.

RESULTSThe procedures were performed successfully in all the patients, with the mean operation time of 198 min (range 135-340 min), average blood loss of 257 ml (range 50-700 ml), and 1 case of blood transfusion, but no postoperative complications. Three cases had positive surgical margins. Postoperative examination at 4 weeks showed PSA > 0.2 microg/L in 2 cases, suggestive of residual tumor, for which maximal androgen block therapy was administered. The other 32 patients were followed up for 3-10 (mean 7.5) months, during which the average level of serum tPSA remained < 0.2 microg/L. Urinary continence was found in 94% (32/34) and 97% (33/34) of the patients at 3 and 6 months, respectively, of whom 77% (26/34) and 88% (30/34) had no urinary leakage (0 pad per day).

CONCLUSIONRLRP, with its advantages of less perioperative blood loss, low rate of positive margin, and good urinary continence, is a safe and effective surgical option for the treatment of prostate cancer.

Purpose:To investigate the prevention and treatment protocol for Af after resection of esophageal and car- dia carcinoma.Methods:Analyses for clinical materials of 1527 patients underwent resection for esophageal and cardiac carcinoma.Results:There were Af 23 cases.Age older than 60 years,abnormal ECG or/and pulmonary function before operation,gastro-esophageal anastomosis above the aortic arch and histological staging Ⅲ～Ⅳ were risk factors for AF.Fa- tal AF was rarely seen.In our 23 cases after treatment in time AF disappeared.Conclusions:Further recognition for post- operative AF and management of perioperative period complication,may reduce the danger of postoperative AF.

Objective To investigate the pathological diagnosis of high-grade intraepithelial neoplasia in gastric biopsy.MethodsOne hundred and forty-three cases diagnosed by gastric biopsy as high-grade intraepithelial neoplasia were analyzed by light microscopy,and were compared with the pathological findings of surgical specimens in 60 cases and a second biopsy in 13 cases.Results Among the sixty cases treated surgically following the gastric biopsies,no carcinoma was found in 6,while the other 54 were diagnosed as gastric adenocarcinoma,27 in advanced stage and 27 in early stage,respectively.Fifteen cases were well-differentiated,24 moderately-differentiated,12 poorly-differentiated and 3 were of mucinous type.Four of the 13 cases with a second biopsy were diagnosed as well-differentiated adenocarcinoma,8 low-grade intraepithelial neoplasia and 1 chronic inflammation.The colorectal adenomas-like changes were morphologically found in 6 surgically-treated cases without carcinoma,5 of whom mucous muscles were not found by biopsy.Fibroblastic reactions were found in 9 cases,all of which were diagnosed as adenocarcinoma in surgical specimens.Conclusion Ninety percent of the cases who are diagnosed as high-grade intraepithelial neoplasia by biopsy may have already been complicated with adenocarcinoma.The location and depth of the specimen in gastric biopsy have a considerable influence on pathological diagnosis.The fibroblastic reaction may be considered as an important marker for gastric adenocarcinoma in pathological diagnosis of gastric biopsy.
