It is confirmed that chronic atrophic gastritis (CAG) caused by Helicobacter pylori is the main cause of gastric precancerous lesions.CAG is also the key determinant in gastric cancer risk assessment,which affects pepsinogen and gastrin-17 secretion.Most of the gastric cancer patients have poor prognosis,and non-invasive tools for gastric cancer screening and diagnosis are lacking.Therefore,the early detection of gastric cancer in order to reduce the disease mortality is necessary.Pepsinogen and gastrin-17 are biomarkers of gastric mucosa and gastric antra.The serological testing for the stomach-specific biomarkers offers the possibility to know preneoplastic gastric mucosal conditions.

Objective To investigate the detection and treatment of carry-over of automatic biochemistry analyzer. Methods We detected the sample carry-over by determining one high level quality control serum and three zero levels serum continuously in five days. We used mixed patients serum to detect the carry-over come from reagent probe, muddler and cuvette by arranging test sequence of different item, combination and the times of rerun. We also used different methods such as immersion, cleaning probe, extended priming to handle the reagent carry-over.Results The sample carry-over was -0.37%～0.48% on new analyzer and 0.51～1.17% on old analyzer, respectively. The carry-over of CHO, TG, HDL on reagent probe and muddler of TBA was 86.9%～208.7% and 86.0%～256.5% on old analyzer, respectively. There was no reagent carry-over among other items on old analyzer. There was no carry-over on reagent probe on new analyzer, the carry-over of different items on cuvette of TBA was -0.9%～1.7%. After immersion, cleaning and extended priming, the carry-over of CHD, TG, HDL on TBA reagent probe fell to -1.1%～2.7% and -0.07%～0.09%, respectively.Conclusions The methods which have been mentioned above can detect the sample and reagent carry-over. The carry-over can be reduced by immersion, cleaning, extended priming and testing in different unit.

OBJECTIVETo explore the treatment methods and outcome of posterior wall fractures of the acetabulum.

METHODSThe data of 31 patients (25 males and 6 females, aged 19-59 years, mean: 40.5 years) with posterior wall fractures of the acetabulum hospitalized in our department from 2002 to 2006 were analyzed retrospectively in this study. The types of fractures, number of fragments, combined dislocations, and sciatic nerve function were documented before admission. All the fractures were treated with open reduction and internal fixation. Based on the fracture type and site, either screws alone or reconstructive plates were used. The patients were immobilized for an average of 12 weeks before partial weight bearing was permitted. After follow-up for 12-70 months (43.6 months on average), modified Merle d'Aubigne score was adopted to evaluate the outcomes of the operations.

RESULTSThe percentages of the excellent, good, fair and poor results were 48.4%, 41.9%, 6.5%, and 3.3%, respectively, with a good to excellent rate of 90.2%. Idiopathic sciatic nerve injury occurred in only one case.

CONCLUSIONSThe sciatic nerve should be routinely exposed and protected during the surgery. The type of fixation should be based on the fracture type and site. Prolonged immobilization may be helpful in improving the final outcomes.

OBJECTIVETo study the surgical treatment for distal humeral fractures in adults according to the follow-up results.

METHODSTwenty-one cases (16 males and 5 females) of distal humeral fracture were included in this study. The average age was 42.5 years (range: 37-52 years). Fractures were classified according to the AO classification system. Nine cases of C1, 8 C2 and 4 C3-type fractures were identified. Open reduction and internal fixation were performed in all cases. A tricep-reflecting approach was adopted, and either the AO orthogonal plating or parallel plating technique was chosen, based on the fracture type. The plaster cast was removed 3 weeks after operation. Rehabilitation was encouraged during this period and afterwards. The average follow-up time was 12.2 months (range: 8-28 months). The outcome was scored according to Aitken and Rorabeek system.

RESULTSNo nerve injury, nonunion or failure of fixation was encountered during the operation and follow-up. However, ossifying myositis occurred in one case.

CONCLUSIONSA triceps-reflecting approach can provide adequate exposure to the joint. The use of AO orthogonal plating or parallel plating techniques based on the type of fractures can provide rigid fixation for the fracture.

Background and purpose: MicroRNAs (miRNAs) play an important role in tumor biological behavior. miRNAs are down-regulated or up-regulated in various cancer types, triggering abnormal cell differentiation, proliferation and apoptosis. This study was designed to investigate the expression and clinical signiifcance of miR-187*in colorectal cancer (CRC), and further to investigate its roles in promoting cell apoptosis. Methods:The expressions of miR-187* in 40 CRC cases were examined by real-time quantitative reverse transcription-PCR (qRT-PCR). The relationship between miR-187*expression and clinical features of CRC was analyzed. HCT116 cells were transfected with a miR-187*mimic and the apoptosis of the transfected cells were examined by lfow cytometry (FCM). Results:The expression of miR-187*was down-regulated in CRC tissues 0.165 (0.106, 0.428) compared with those in normal tissues 0.334 (0.211, 0.712) (P<0.05), especially in mucinous carcinoma and older age CRC (P<0.05). Transfection of HCT116 cells with a miR-187*mimic up-regulated the expression of miR-187*and increased cell early apoptosis (P<0.05). Conclusion: The expression level of miR-187* was lower in CRC. miR-187* expression correlates with histological type and age. Transfection of HCT116 cells with a miR-187*mimic accelerates apoptosis of tumor cells, suggesting that miR-187*is a potent tumor suppressor.

Objective To evaluate the relationship between histone deacetylase 3 (HDAC3) expression and the mechanism underlying mitigation of remifentanil postconditioning-induced protection of diabetic cardiomyocytes.Methods H9c2 cells were cultured in DMEM/F12 culture medium supplemented with 10％ fetal bovine serum.The cells were seeded in 6-well plates (2 ml/well) at a density of 105 cells/ml.After the cells were cultured for 12 h,the cells were attached to the wall and cultured for 48 h in the normoglycemic (5.5 mmol/L) or hyperglycemic (25 mmol/L) DMEM culture medium.The cells were then randomly divided into 6 groups (n =18 each) using a random number table:control group (group CON),hypoxia/reoxygenation group (group H/R),remifentanil postconditioning group (group RPC),hyperglycemia group (group HG),hyperglycemia plus hypoxia/reoxygenation group (group HG-H/R),and hyperglycemia plus remifentanil postconditioning group (group HG-RPC).In H/R,RPC,HG-H/R and HG-RPC groups,the cells were exposed to 95％ N2-5％ CO2 in an incubator for 5 h after changing the culture medium for Tyrode solution.In H/R and HG-H/R groups,the culture medium was changed to the DMEM/F12 culture medium supplemented with 10％ fetal bovine serum and glucose at the corresponding concentration,and the cells were then incubated for 1 h.In RPC and HG-RPC groups,the cells were incubated in the DMEM culture medium containing remifentanil at the final concentration of 1 μmol/L,and the cells were then incubated for 1 h.At 1 h of reoxygenation,the cell viability was measured by CCK-8 assay,the cell apoptosis was detected by AnnexinV-FITC/PI flow cytometry,and the expression of HDAC3 and caspase-3 in cells was detected by Western blot.The apoptotic rate was calculated.Results Compared with group CON,the cell viability was significantly decreased,the cell apoptotic rate was significantly increased,and the expression of caspase-3 and HDAC3 was significantly up-regulated in group H/R (P＜ 0.05).Compared with group H/R,the cell viability was significantly increased,the apoptotic rate was significantly decreased,and the expression of caspase-3 and HDAC3 was significantly down-regulated in group RPC (P＜0.05).Compared with group HG,the cell viability was significantly decreased,the apoptotic rate was significantly increased,and the expression of cspase-3 and HDAC3 was significantly up-regulated in group HG-H/R (P＜0.05).There was no significant difference in the parameters mentioned above between group HG-RPC and group HG-H/R (P＞0.05).Conclusion The mechanism underlying mitigation of remifentanil postconditioning-induced protection of diabetic cardiomyocytes is associated with hyperglycemia-induced up-regulation of HDAC3 expression.

Objective To investigate the relationship between maintaining concentration and loss of consciousness (LOC) concentration of propofol target controlled infusion (TCI) in patients undergoing heart valve replacement.Methods Thirty patients undergoing elective heart valve replacement were enrolled to receive propofol by ladder plasma TCI for anesthesia induction,8 males and 22 females.The initial plasma concentration (Cp) of propofol was set to 1.0 μg/ml,0.3 μg/ml Cp was increased every 1 min until LOC when the prediction effect-cite concentration (Ce) reached 0.5 μg/ml,then sufentanil 0.8-1.0 μg/kg and rocuronium 0.6-0.9 mg/kg were given for intubation.When BIS reached 50,Cp was decreased to the level of Ce.All the surgeries were performed under hypothermia CPB.MAP,HR,CVP,CO,SV,SVR,BIS,propofol Cp and Ce values were recorded at baseline (T0),LOC (T1),BIS reached 50 (T2),and other time points during operation (T3-T9).The correlation analysis between propofol Ce at LOC and perioperative variables were completed.Results In correlation analysis,there was a significant positive correlation between propofol Ce at LOC and baseline CO,SV (P<0.01),there was a significant negative correlation between propofol Ce at LOC and age (P<0.05),there was a significant positive correlation between propofol Ce at LOC and propofol Ce at T2-T9(P<0.01).Conclusion In patients undergoing valvular replacement,the Ce of propofol at maintenance are related to the concentration of propofol at LOC,which is helpful for adjusting the Ce of propofol at maintenance according to the Ce of propofol at LOC.
