Objective To study the association between endometrioid uterine carcinomas and metabolic syndrome (MS). Methods A retrospective study was conducted on 123 patients who were admitted in Department of Gynecology Oncology, Zhejiang Cancer Hospital (study group) and 90 healthy women (control group) with matching age from Jan. 2005 to Mar. 2009. The general conditions[including age, whether menopausal, body mass index (BMI)];the risk factors for MS [including waist circumference,fasting plasma glucose, triglycerides(TG), high-density lipoprotein (HDL) and systolic and diastolic blood pressure]were analyzed. The clinical stage, histological type, and pathology differentiated degree of study group with or without MS were also analyzed by univariate analysis and Cox proportional hazards models.Results (1) The univariate survival analysis shown that there were no significant difference with age in two groups[(54.3±0.6) vs. (54.2±0.9) years;P>0.05], while the rate of menopausal, BMI(≥25 kg/m~2), the cases coupled with MS, the size of waist circumference (> 80 cm), the level of fasting plasma glucose (≥5.6 mmol/L),TG(> 1.7 mmol/L)and abnormal systolic and diastolic blood pressure in study group were higher than those in control group (67.5% vs. 48. 9%, 45.5% vs. 23.3%, 43.9% vs.18.9%, 50.4% vs. 27.8%, 53.7% vs. 21.1%, 40.7% vs. 21.1% and 40.7% vs. 25.6%,respectively, all P <0.05). The percentage of HDL(< 1.30 mmol/L) was higher in study group than that in control granp(63. 4% vs. 32. 2%, P <0.05). (2) There were not significant difference for the clinical stage, pathological type, grades between patients with or without MS in study group (P > 0.05). (3) The Logistic multivariate survival analysis shown that central obesity, higher TG, lower HDL and abnormal plasma glucose were independent risk factors for endometrioid uterine carcinomas coupled with MS (P< 0.05). Conclusion Metabolic syndrome is marginally associated with an increased risk of endometrioid uterine carcinomas, which may be the new point to screen, prevention and treatment endometrioid uterine carcinomas.

OBJECTIVEThis study is to understand the difference of semen quality among the different areas and the related factors.

METHODSFive hundred and sixty-two people were under from seven provinces.

RESULTSResults showed that the quantity and density of semen, the rate of moving forward semen, livability, percent age of normal formed semen and the total number of semen were statistically different among the seven areas. The difference was ranged as 28.82%, with the highest 2.95 ml in Shanxi province and the lowest 2.29 ml in Henan province. Geometric mean of semen density was found the lowest 36.27 x 10(6)/ml in Guizhou province, next to it was 42.52 x 10(6)/ml in Shandong province and the highest was 74.77 x 10(6)/ml in Hebei province. The percent age with forward progression of semen was seen the lowest 44.40% in Henan province, followed by 51.88% in Hebei province and 52.88% in Zhejiang province and the highest were 76.50% in Shanghai, 75.24% in Shanxi province, with a range of 72.30%. The highest semen viability was 85.89% in Shanghai, while the lowest 72.35% in Henan, with a range of 18.71%. Normal sperm morphology was seen the lowest 68.45% in Hebei province, with the highest 88.06% in Guizhou province, and the range was 28.65%. The geometric mean of total sperm count was seen the highest 204.23 x 10(6)/ml in Hebei province and the lowest 77.69 x 10(6)/ml in Guizhou province. Results showed through analysis of variance that some indexes were different in some provinces.

CONCLUSIONThe results indicated that the semen quality was different in different regions in China and its influential factors may be region and geography environment.

OBJECTIVETo determine the clinical value of 24 h double-probe pH-metry for the diagnosis and treatment of laryngopharyngeal reflux (LPR).

METHODSAccording to the pH-metry results (whether the reflux events record in the upper esophagus is more than 6.9), patients of refractory pharyngolaryngitis were divided into LPR and control groups (each of 17 cases). All patients treated with anti-acid therapy and conventional pharyngo-laryngitis therapy. Correlation between pH-metry and the reflux symptom index (RSI), the reflux symptom index (RFI) were analyzed. Changes of the RSI and RFI in different group were calculated in post-treatment.

RESULTSIn the LPR group, the median reflux events of the upright time were higher than the supine time (Z = -3.62, P < 0.01), but the difference was not discovered in the control group (Z = -0.60, P > 0.05). There was no statistical difference between RSI, RSI and RFS with pH-metry, and with moderate concordance (k were 0.47, 0.53, P < 0.01, respectively). Compared to pre-treatment, the RSI and RFI were decreased both in LPR group and control group, Amplitude decreased in LPR group significantly higher than the control groups, with statistical difference (t were 3.74, 3.01, P < 0.01, respectively).

CONCLUSIONThe 24 h double-probe pH-metry is significant for the anti-acid therapy of LPR.

OBJECTIVETo investigate the effects of carvedilol on stabilizing atherosclerosis plaque.

METHODSForty five male Japanese white rabbits were divided randomly into 5 groups with 9 for each. One group was fed up with normal diet as blank control. In other four groups, the common carotid artery of rabbits fed up with high cholesterol diet were injured by balloon. Three groups of them were transfected by wild-type p53 gene 8 weeks later, and then two groups of them were treated with carvedilol (3 mgxkg(-1)xd(-1)) and metoprolol (6 mgxkg(-1)xd(-1)) respectively, high cholesterol diet should be continued for other 4 weeks. Serum lipid, hypersensitive C-reaction protein (hsCRP), oxidized low density lipoprotein (oxLDL), superoxide dismutase (SOD), malondialdehyde (MDA) and glutathione peroxidase (GSH-PX) were measured in 0, 8, 12 weeks after experiment. The apoptosis rate of smooth muscle cell (SMC) in endomembrane and the local expression of p53, bcl-2, bax, alpha-actin were examined after experiment, and the carotid arteries were examined by light microscopy and transmission electron microscopy.

RESULTSThe typical carotid atherosclerotic plaques were observed in balloon-injured groups. The local expression rates of p53 in groups transfected by wild type p53 gene were higher obviously than them in other two groups (P < 0.01). Compared with the rabbits received simple transfection, the thickness of the fibrous cap in rabbits received carvedilol and metoprolol were all increased, but the change could be observed significantly in carvedilol group (P < 0.05). Compared with metoprolol, carvedilol could reduce the level of serum hsCRP, oxLDL, MDA, and increase the concentration of SOD and GSH-PX significantly (P < 0.05 or 0.01), but two medicines had no obvious influence to serum lipid. The apoptosis rate of SMC in endomembrane, the local expression of bax gene and bax/bcl-2 ratio were decreased, the positive expression rates of alpha-actin and bcl-2 were enhanced in carvedilol group (P < 0.01).

CONCLUSIONSBoth carvedilol and metoprolol can improve the stability of the plaque, but carvedilol is superior. Its mechanisms may lie in that carvedilol still has function of anti-inflammation, anti-oxidation, decreasing the apoptosis rate of SMC in addition to its function of blocking beta-receptor.

OBJECTIVETo explore the possibility of using melanoma antigen (MAGE)-1 and MAGE-3 gene encoding proteins as an index of potential target for immunotherapy in intrahepatic cholangiocarcinoma (IHCC) patients.

METHODSThe expressions of MAGE-1 and MAGE-3 genes in tumor tissues and tumor adjacent non-IHCC liver tissues were examined by RT-PCR method. The relationship between positive expression rates of MAGE-1 and MAGE-3 genes and clinical data including sex, age, tumor diameters, tumor envelope, tumor nodules number, and hepatitis B virus surface antigen were determined.

RESULTSThe positive expression rates of MAGE-1 (35%) and MAGE-3 genes (45%) were significantly higher in the tumor tissues than in tumor adjacent tissues (0) (P<0.01). The positive expression rates of MAGE-1 and MAGE-3 genes had no relationship with the clinical data (P >0.05), except the morphology of tumor (P <0.05).

CONCLUSIONThe high expression rates of MAGE-1 and MAGE-3 genes in IHCC suggests the MAGE-1 and MAGE-3 gene may be a target for immunotherapy in IHCC patients.

Objective: To explore the changes of inflammatory factors and related factors in the population with overweight combining abdominal obesity and high-normal blood pressure (BP). Method: Our research included in 2 groups: Group A: n=189 subjects with high-normal BP, overweight and abdominal obesity, their BMI ≥ 24 kg/m2, waist circumference (WC) ≥ 90 cm in male, WC ≥ 85 cm in female, SBP(120-139) mmHg or DBP (80-89) mmHg; Group B, n=87 healthy subjects with matched age, BMI < 24 kg/m2, BP < 120/80 mmHg as normal control. Blood lipids and other biochemical parameters were examined; serum levels of intercellular adhesion molecule-1 (ICMA1), monocyte chemoattractant protein-1 (MCP1), chemokines-1 (CXCL-1), CXCL-2 and oxidized low density lipoprotein (oxLDL) were measured by ELISA. Results: Compared with Group B, Group A had increased TG, fasting blood glucose and non-HDL-C, all P<0.05; elevated serum levels of ICMA1 and MCP1, both P<0.05. Correlation analysis indicated that in Group A, ICMA1 was positively related to BMI, SBP, LDL-C and negatively related to age, which had gender difference; MCP1 was positively related to WC, SBP, LDL-C, non-HDL-C and negatively related to HDL-C, which also had gender difference; oxLDL was positively related to SBP, LDL-C; no evidence showed that CXCL-1 and CXCL-2 were related to obesity, BP and metabolic parameters; in Group B, no evidence showed that inflammatory factors were related to the other parameters. Linear regression analysis for inflammatory parameters found that after excluding other factors, in Group A, ICMA1 was positively related to BMI (t=2.901, P=0.005); in male gender, MCP1 was positively related to SBP (t=5.076, P=0.000), negatively related to DBP (t=-3.369, P=0.001). oxLDL was positively related to age (t=2.168, P=0.032) and LDL-C (t=2.146, P=0.034); CXCL-1 was negatively related to HDL-C (t=-2.013, P=0.047). Conclusion: The subjects with overweight abdominal obesity and high-normal BP were usually having abnormal metabolism of glucose and lipids, elevated serum levels of inflammatory parameters, blood levels of inflammatory factors were increasing with elevated BMI and SBP accordingly which implied the association with critical range of BP.

OBJECTIVEThe predictive value of postoperative hepatic function evaluated by liver functional imaging combined with single photon emission computed tomography (SPECT) technique was appraised in the present study.

METHODSTwenty New Zealand white rabbits were divided randomly into two groups, including the Hepatic Fibrosis with Carcinoma Group (FC-Group, n = 10) and the Control Group (C-Group, n = 10). All the rabbits underwent the resection of outer-right lobe of the liver. The whole hepatic function indexes, such as HCI(5), HLI(5) and Ex(15), and the hepatic function remnant indexes, including HCI(5P), HLI(5P) and Ex(15P), were calculated by 99mTc-EHIDA liver imaging.

RESULTSEx(15) of FC-Group was lower than that of C-Group (P < 0.05). HCI(5) and HLI(5) of FC-Group had the trends to increase compared with the C-Group. Ex(15) was positively correlated with ALB, and negatively correlated with TBil and GGT (P < 0.05). HCI(5) had a positive correlation with CHE (P < 0.05), while HLI(5) had a negative correlation with A/G (P < 0.05). HLI(5P) had the negative correlation with postoperative A/G (P < 0.05), and Ex(15P) had the negative correlation with postoperative TBil and GGT (P < 0.05).

CONCLUSIONSThis study has established a method of 3-D liver function evaluation system on an animal model. Among the indexes, Ex(15) can exactly represent the whole liver function while Ex(15P) and HLI(5P) can predict the liver function after the liver resection. The results may help the future clinical use of this technique to evaluate the risk of operation.

OBJECTIVETo observe the precise time of the recurrence after resection of hepatocellular carcinoma (HCC) and to further explore the risk factors associated with postoperative recurrence.

METHODSTotally 94 patients who had undergone resection of HCC were divided into three groups based on the time of recurrence, which was indicated by the digital subtraction angiography (DSA) examination: recurrence between 1 to 6 months, recurrence between 7 to 12 months, and tumor-free after 12 months. Patients with intra-hepatic recurrence were treated with transcatheter arterial chemoembolization and confirmed by CT scans after embolization, contrast-enhanced ultrasound, or magnetic resonance imaging.

RESULTSThe recurrence rates of 6 months and 1 year were 30.9% and 36.2%, respectively. No statistically significant difference between 6-month and 1-year recurrence rates was observed. Nine (26.5%) patients with recurrence and five (8.3%) patients free of tumor had previously presented as multifocal HCC, which showed a statistical significance (P = 0.032). The diagnostic accuracy of DSA was 87.2%, which was eventually confirmed by the other investigations.

CONCLUSIONSMost recurrences occure within the first six months postoperatively and multifocal carcinogenesis is one of the risk factors associated with early recurrence after liver resection for advanced HCC. DSA is an important surveillance for early detection of intra-hepatic recurrence after surgery; meanwhile, it also provides information for early management to control the disease progression and for future active therapies.

OBJECTIVETo establish a three-dimentional liver function evaluation system using 99mTc-diethyl iminodiacetic acid (99mTc-EHIDA) scintigraphy based on single photon emission computed tomography (SPECT).

METHODSTotally 16 patients with liver lesions were divided into cirrhosis group and non-cirrhosis group. SPECT was performed 2 days before operation and 5 days after operation. Serum liver functions were examined on the same day of scintigraphy. SPECT images of areas of interest of heart and liver were aquired. Time of the peak of EHIDA density in liver (Tpeak), five-minutes heart liver index (HLI5), blood clearance index (HH15), receptor index (LHL15), and the predictive values were calculated.

RESULTSTpeak was not significantly different between two groups, while HLI5, HH15, and LHL15 were significantly different (P = 0.033, P = 0.001, and P = 0.005). HLI, and LHL15 were significantly correlated with preoperative total protein and prealbumin levels (P = 0.003, P = 0.015, P = 0.022, P = 0.038) and post-operative prealbumin (P = 0.037, P = 0.042). The predictive values of HLI5 and LHL15 correlated well with postoperative HLI5 and LHL15 (r = 0.675, P = 0.016; r = 0.629, P = 0.028).

CONCLUSIONThe three-dimentional liver function evaluation system using 99mTc-EHIDA based on liver SPECT may facilitate the further studies of risks of liver surgery.

OBJECTIVETo summarize the surgical experiences, risks, complications, and managements for hepatic masses in difficult sites.

METHODSTotally 47 patients were divided into three groups based on the liver tumor sites: primary porta hepatis group, secondary porta hepatis group, and caudate lobe group. All patients underwent different portion of hepatectomy.

RESULTSThe surgery duration was (289.6 +/- 62.2) ml-nutes, intra-operative blood loss was (602.3 +/- 256.4) ml, and intra-operative blood transfusion was (524.0 +/- 325.9) ml. Incidence of surgical complications in each group was 61.5%, 26.9%, and 25%, respectively. Serious complications observed were biliary leakage (27.7%), bleeding (6.4%), and post-operative liver failure (2.1%). Three perioperative deaths were reported: two patients died of bleeding, and one patient died from liver failure.

CONCLUSIONSDissection of the liver and exposure of major blood vessels and biliary ducts are of critical importance in the surgeries for hepatic masses in difficult sites, and post-operative complications may be remarkably reduced through delicate manipulations of the small intra-hepatic vessels and biliary ducts during resection. A thorough pre-operative evaluation plays a key role in predicting the feasibility and risks of the surgery. Damage to the major blood vessels adjacent to the tumor, in addition to bleeding, may result in in-flow or outflow obstruction and cause necrosis of the corresponding hepatic lobe. Compared with damage to the primary portal area, vascular damage to the secondary porta is generally associated with higher fatality.
