OBJECTIVETo explore the best program for treatment of irritable bowel syndrome (IBS) of constipation type.

METHODSNinety-five cases of IBS were randomly divided into 3 groups. Group A (n = 30) were treated by acupuncture combined with microorganism pharmaceutical preparations, group B (n = 35) by oral administration of medicine for loosening the bowel to relieve constipation plus microorganism pharmaceutical preparations, and group C (n = 30) by simple acupuncture.

RESULTSThe total effective rates were 90.0%, 77.2% and 66.7%, in the group A, B and C, respectively, with a very significant differences as the group A compared with those in the groups B, C (P < 0.01), and with no significant difference as the group B compared with that of the group C (P > 0. 05). The intestinal available bacteria, bilidobacteria and lactobacillus, increased and enteric bacilli decreased in varying degrees in the 3 groups.

CONCLUSIONAcupuncture combined with microorganism pharmaceutical preparations has a better therapeutic effect on irritable bowel syndrome of constipation type.

Objective To investigate the effect of β1-Adrenoceptor autoantibody on liver function.Methods The biologically active of β1-AA was prepared and passive immunization model was established with β1-AA.The bio-chemical parameters of the liver were measured by the automatic serum biochemical analyzer.The liver size, hepatic vein,portal vein velocity were detected by liver ultrasound;hepatocytes apoptosis were tested by tunel stai-ning,annexin V/PI staining and caspase 3 activity detection.Results The biologically active of β1-AA and passive immunization model were established successfully.The ALT and AST of the liver significantly increased and the ALB decreased in the passive immunization process.The apoptosis of the hepatocytes increased,and meto-prolol partially reversed this effect.Conclusions β1-AA may induce hepatocytes apoptosis by β1-adrenergic receptor and participate in the development of liver injury.

OBJECTIVETo analyze the risk factors for hospital mortality after operations for type A aortic dissection.

METHODSTotally 766 consecutive patients (586 male and 180 female patient, aged (45±12) years, ranging from 16 to 78 years), who underwent surgery for type A aortic dissection from January 2001 to December 2010, were studied retrospectively. Preoperative and operation related clinic factors were analyzed by univariate analysis, followed by Logistic regression model, to identify the risk factors of hospital mortality.

RESULTSOverall, 37 patients (4.8%) died during hospitalization. On univariate analysis, significant risk factors for hospital mortality were male, acute status, renal dysfunction, cardiac dysfunction, cardiopulmonary bypass time, duration of operation, volume of blood transfusion, re-operation for bleeding (χ2=4.008-27.093, P<0.05). On Logistic regression model, independent risk factors were acute status (OR=2.784, 95%CI: 1.166-6.649, P=0.021), renal dysfunction (OR=6.285, 95%CI: 1.738 - 22.723, P=0.005), cardiac dysfunction (OR=3.052, 95%CI: 1.083-8.606, P=0.035), re-operation for bleeding (OR=3.690, 95%CI: 1.262-10.791, P=0.017), volume of blood transfusion (OR=1.033, 95%CI: 1.008-1.058, P=0.010). Additionally, male (OR=0.387, 95%CI: 0.177-0.848, P=0.018) was protective factor, and alternatively, female was indeed one of the independent risk factors for hospital mortality.

CONCLUSIONFemale, acute status, renal dysfunction, cardiac dysfunction, re-operation for bleeding, volume of blood transfusion were independent risk factors for hospital mortality after operations for type A aortic dissection.

BACKGROUNDThere has been an increase in the incidence of breast cancer in China, but no definite risk and protective factors for breast cancer have been identified in Chinese females. This study was designed to identify the risk factors for female breast cancer in North and East China.

METHODSA 1:3 matched, case-control study was conducted. All of the subjects in the case and control groups were selected from a previous epidemiological survey of 122 058 females aged 25 to 70 years. Single and multiple Logistic regression analyses were used to study potential factors in the development of breast cancer.

RESULTSSignificant differences at the level of α=0.20 between case and control groups were observed for the following factors: economic status, social status, family annual income, bean product consumption, body mass index (BMI), family history of breast cancer in the first or second degree, number of miscarriages, menstrual pattern, benign breast disease history, nipple leakage, inverted nipple, history of diabetes mellitus, history of hypertension, history of ovarian cyst, physical exercise, current and global quality of life satisfaction, healthy behavior and prevention, and scores of breast cancer-related knowledge. After Cox-regression model analysis (α=0.10), six factors were found to be significantly related to breast cancer, of which the ORs and 95%CIs were: BMI, 1.696 (1.169-2.460, P=0.005); benign breast disease history, 2.672 (0.848-8.416, P=0.093); family history of breast cancer, 7.080 (1.758-28.551, P=0.006); number of miscarriages, 1.738 (1.014-2.978, P=0.044); global quality of life satisfaction, 3.044 (1.804-5.136, P=0.000); healthy behavior and prevention, 3.294 (1.692-6.412, P=0.000).

CONCLUSIONSA comprehensive range of factors related to breast cancer was identified. Women should be educated about a healthy lifestyle, especially those with a family history of breast cancer or a personal history of benign breast disease.

OBJECTIVETo summarize the experience of one-stage total and subtotal aortic replacement for aneurysm evolving the entire aorta and show the midterm results of the operation.

METHODSFrom February 2004 to July 2008, 22 patients (17 men and 5 women, age ranged from 19 to 47 years old) underwent one-stage total or subtotal aortic replacement under deep hypothermic circulatory arrest and selective antegrade cerebral perfusion. Seven patients received subtotal aortic replacement (from the aortic valve to the abdominal aorta). Fifteen patients underwent total aortic replacement (from the aortic valve to the aortic bifurcation). Patients were opened with a mid-sternotomy and a thoracoabdominal incision. First, the ascending aorta was replaced; following which the aortic arch was reconstructed. Finally, the thoracoabdominal aorta was fully replaced.

RESULTSThirty-day mortality was 4.5% (1/22). One patient died of multiple organ failure 11 days postoperatively. Two patients had cerebral infarction secondary to embolism. Spinal neurological deficits didn't occur. Twenty-one patients survived the operation and were followed up for 3 to 56 months (35.0 +/- 16.9 months). There was no late death. One patient received aortic valve replacement due to aortic valve regurgitation one year after David and total aortic replacement.

CONCLUSIONOne-stage total and subtotal aortic replacement is an effective operation for aneurysm evolving the whole length of the aorta with acceptable mortality and morbidity. Midterm follow-up showed satisfactory results.

OBJECTIVETo investigate the characteristics of RET/PTC and H47PTEN rearrangement and the association between gene rearrangement and clinicopathological properties of thyroid carcinoma.

METHODSRearrangement of RET/PTC-1, RET/PTC-2, RET/PTC-3, ELKS-RET and H4-PTEN (H4/PTEN and PTEN/H4) was analyzed in 139 thyroid tumor tissues by using RT-PCR and sequencing.

RESULTSTwelve RET/PTC-1, 6 RET/PTC-3, 6 H4/PTEN and 7 PTEN/H4 were detected in 126 papillary thyroid carcinomas. In 3 cases, both RET/PTC and H4-PTEN were identified simultaneously. However, repeated experiments did not give the same results of H4-PTEN rearrangement. The overall frequency of rearrangement was 21.4% (27/126). The patients with gene rearrangement were younger (P = 0.02) and had a higher frequency of lymph node involvement (P = 0.02). High frequency of lateral neck lymph node involvement was detected in RET/PTC positive PTC (P < 0.01). PTEN/H4 rearrangement could also be detected in medullary thyroid carcinoma (2/5).

CONCLUSIONSH4-PTEN rearrangement can occur simultaneously with RET/PTC rearrangement in PTC. High predisposition to gene rearrangement is a characteristic of PTC. The patients of PTC with gene rearrangement are younger and have a higher frequency of lymph node involvement.

OBJECTIVETo investigate the surgical approach, feasibility and effectiveness of laparoscopic Roux-en-Y gastric bypass (LRYGB) surgery for treating type 2 diabetes mellitus.

METHODSSeven obese patients with type 2 diabetes and 5 type 2 diabetic patients without obesity received LRYGB surgery. The changes of the body mass, fasting blood glucose (FBG), 2-hour postprandial blood glucose (2 h PBG), C peptide (C-P) and HbA1c% were observed postoperatively.

RESULTSLRYGB procedures were successfully performed in all the 12 patients with no conversion to open surgery. The resolution rate was 85.7% in the obese group and 80% in the non-obese diabetic group.

CONCLUSIONLRYGB surgery is feasible for treatment of type 2 diabetes with good short-term result, but the long-term outcome awaits further observation.

OBJECTIVETo compare short-term postoperative outcomes between antecolic and retrocolic laparoscopic Roux-en-Y gastric bypass(LRYGB).

METHODSForty obesity patients were admitted into The First Affiliated Hospital of Jinan University from March 2008 to July 2010. All patients were randomly assigned to undergo antecolic (group A, 20 cases) and retrocolic (group B, 20 cases) gastroenteric anastomosis. Short-term outcomes were compared.

RESULTSLRYGB procedures were successfully performed in all the 40 patients. There were no significant differences between the two groups in estimated blood loss during surgery, time to flatus passage, time to resumption of oral intake, or length of postoperative hospital stay. The operation time was longer in group B than that in group A [(163.4±28.1) min vs.(131.8±22.7) min, P<0.05]. There were no patients developed internal hernia or anastomotic leakage in either group. Comparison of short-term gastrointestinal symptoms after surgery showed no statistical significance.

CONCLUSIONSAlthough retrocolic procedure may be closer to anatomical structure, antecolic and retrocolic anastomosis have comparable short-term outcomes after surgery. Further study is warranted to investigate long-term outcomes.

PURPOSE: We previously found that the histone methyltransferase suppressor of variegation, enhancer of zeste, trithorax and myeloid-nervy-deformed epidermal autoregulatory factor-1 domain-containing protein 3 (SMYD3) is a potential independent predictive factor or prognostic factor for overall survival in gastric cancer patients, but its roles seem to differ from those in other cancers. Therefore, in this study, the detailed functions of SMYD3 in cell proliferation and migration in gastric cancer were examined. MATERIALS AND METHODS: SMYD3 was overexpressed or suppressed by transfection with an expression plasmid or siRNA, and a wound healing migration assay and Transwell assay were performed to detect the migration and invasion ability of gastric cancer cells. Additionally, an MTT assay and clonogenic assay were performed to evaluate cell proliferation, and a cell cycle analysis was performed by propidium iodide staining. Furthermore, the expression of genes implicated in the ataxia telangiectasia mutated (ATM) pathway and proteins involved in cell cycle regulation were detected by polymerase chain reaction and western blot analyses. RESULTS: Compared with control cells, gastric cancer cells transfected with si-SMYD3 showed lower migration and invasion abilities (P<0.05), and the absence of SMYD3 halted cells in G2/M phase and activated the ATM pathway. Furthermore, the opposite patterns were observed when SMYD3 was elevated in normal gastric cells. CONCLUSIONS: To the best of our knowledge, this study provides the first evidence that the absence of SMYD3 could inhibit the migration, invasion, and proliferation of gastric cancer cells and halt cells in G2/M phase via the ATM-CHK2/p53-Cdc25C pathway. These findings indicated that SMYD3 plays crucial roles in the proliferation, migration, and invasion of gastric cancer cells and may be a useful therapeutic target in human gastric carcinomas.

OBJECTIVETo determine the incidence and risk factors of HCV infection among heroin addicts who were receiving methadone maintenance treatment(MMT)in Dehong prefecture, Yunnan province.

METHODSAll heroin addicts who were HCV negative at the initiation of MMT in June 2005 through March 2012, in Dehong prefecture, were included in this cohort analysis. HCV incidence was calculated and related risk factors determined by using Cox proportional hazard regression model.

RESULTSA total of 2390 MMT clinic attendants were qualified for this cohort study by March 2012. 731(30.6%) of them had never received any follow-up HCV testing so were recognized as loss to follow-up. The other 1659 (69.4%) participants had received at least one follow-up HCV testing and were observed for a total of 3509.12 person-years(py). During this period 99 new HCV infections or HCV sero-converters were identified. The overall HCV incidence was 2.82/100 py and was 3.62/100 py for 2006, 5.36/100 py for 2007, 6.71/100 py for 2008, 2.56/100 py for 2009, 1.90/100 py for 2010, and 0.44/100 py for 2011, respectively. Results from multiple regression analysis, using Cox proportional hazard model, indicated that after controlling for confounding variables, those who were unemployed, being injecting drug users(IDUs)or HIV positive at entry into the MMT program were more likely to be newly infected with HCV or HCV sero-converted during the follow-up period than those who were peasants, non-IDUs or HIV negative at entry into the MMT program(HR = 2.02, 95% CI:1.18-3.48; HR = 9.05, 95% CI:5.49-14.93; HR = 2.12, 95% CI: 1.37-3.56), respectively.

CONCLUSIONThe incidence of HCV infection among MMT clinic attendants was decreasing since 2009 in Dehong prefecture. Those who were unemployed, injecting drug users and HIV positive were at higher risk of HCV infection.
