Objective To investigate the relationship between pancreatic cancer and diabetes mellitus (DM). Methods Two hundreds and twenty patients with pancreatic cancer and 300 controls, who suffered from non-digestive tract, non-neoplastic or non-hormone-related disorders, were enrolled from 1997 to 2007. The incidence of diabetes between the two groups and the relationship between pancreatic cancer and diabetes were compared, pancreatic cancer patients with DM were compared with patients without DM for their gender, age, location and differentiate degree of the cancer. Results The incidence of DM in the two groups were 33.1% and 9.67%, respectively, and the difference was significant (P < 0.05). In the pancreatic cancer group, the proportion of patients with DM diagnosed within 2 years or for more than 10 years were 25.91% (57/73) and 3.18% (7/73), which were significant higher than those in the control group 6.0% (18/29) and 0.67% (2/29)) (χ2=46.15, P<0.01, 0R=6.07; χ2 =4.72, P<0.01, OR=4.90). In the pancreatic cancer group, the proportion of patients with DM diagnosed within 2～5 years or 5～10 years was not significant different when compared with that of the control group, and there was no significant difference in terms of gender, age and cancer location between the pancreatic cancer patients with DM and without DM. The majority of pancreatic cancer patients with DM had corpora mammillaria or well differentiated adenocarcinoma, and the majority of pancreatic cancer patients without DM had differentiated adenocarcinoma. Conclusions DM was closely related with pancreatic cancer and DM may be one of the presentations of pancreatic cancer, as well as a possible risk factor for the tumor.

Objective To investigate the effect of dexmedetomidine on emergence agitation (EA) following sevoflurane anesthesia in children with cerebral palsy.Methods Fifty ASA physical status Ⅰ or Ⅱ children with cerebral palsy of both sexes,aged 2-12 yr,scheduled for elective muscle strength muscle tension adjustment method,were randomly allocated into 2 groups (n =25 each):control group (group C) and dexmedetomidine group (group D).Anesthesia was induced with iv injection of sufentanil 0.3 μg/kg,cisatracurium 0.15 mg/kg,and propofol 1.5 mg/kg.The patients were tracheal intubated and mechanically ventilated.Dexmedetomidine 0.5 μg/kg was intravenously infused over 15 min after induction of anesthesia in group D and the equal volume of normal saline was given in group C.The operation was begun at the end of administration.Anesthesia was maintained with inhalation of 2％-4％ sevoflurane and the concentration was adjusted to achieve a target BIS value of 45-60.The heart rate,systolic blood pressure and diastolic blood pressure were recorded before infusion of dexmedetomidine (T1) and at skin incision (T2).The extubation time,emergence time and consumption of sevoflurane were also recorded.The end-tidal sevoflurane concentration was recorded at T1,T2,and the end of operation (T3).The adverse cardiovascular events and occurrence of EA were also recorded.The degree of EA was assessed using the Pediatric Anesthesia Emergence Delirium (PAED) scale.The peripheral venous blood samples were collected at T1,T2,T3 and extubation (T4) for determination of the blood glucose level and serum cortisol concentration.Compared with group C,the emergence time and extubation time were significantly shortened,and the consumption of sevoflurane,end-tidal sevoflurane concentrations at T2 and T3,PAED scores,incidence of agitation,and the blood glucose level and serum cortisol concentration at T4 were significantly decreased in group D (P ＜0.05 or 0.01).There was no significant difference in the incidence of bradycardia or heart rate,systolic blood pressure and diastolic blood pressure at each time point between the two groups (P ＞ 0.05).Conclusion Dexmedetomidine can decrease the development and degree of EA following sevoflurane anesthesia in children with cerebral palsy.

Objective To evaluate the effect of cerebral palsy factor on the sensitivity of postopera?tive pain in the pediatric patients. Methods Twenty?five pediatric patients with cerebral palsy of both se?xes, of American Society of Anesthesiologists physical statusⅠorⅡ, aged 3-7 yr, weighing 11-25 kg, scheduled for elective lower abdominal or lower extremity surgery, served as cerebral palsy group ( group P). Another 25 pediatric patients without cerebral palsy of both sexes, of American Society of Anesthesiol?ogists physical status Ⅰ orⅡ, aged 3-7 yr, weighing 11-25 kg, served as control group ( group C) . At 2 h after surgery, pain was evaluated by using CRIES ( crying, requires O2 saturation, increased vital sign, expression and sleeplessness) . Peripheral venous blood samples were collected before surgery, and at 2 and 24 h after surgery, and the concentrations of plasmaβ?endorphin were measured by radio?immunity method, and the concentration of plasma catecholamine ( adrenaline) was determined by high performance liquid chromatography. Results Compared with the value before surgery, the plasma concentrations of β?endorphin were significantly decreased, and the concentrations of plasma catecholamine were increased after surgery in the two groups (P < 0?01). Compared with group C, the CRIES score was significantly in?creased after surgery, the concentration of plasmaβ?endorphin was decreased before and after surgery, and the concentration of plasma catecholamine was increased after surgery in group P ( P< 0?05 or 0?01) . Con?clusion The sensitivity of postoperative pain is increased in the pediatric patients with cerebral palsy.

Objective:To analyze the expression of MUC15 and PI3K/Akt in gastric carcinoma and its association with clinicopathologi-cal characteristics and prognosis. Methods:The expression of MUC15 and Akt was detected in 144 cases of gastric carcinoma tissues and corresponding para-carcinoma tissues by tissue microarray and immunohistochemistry. Results:The positive expression rate of MUC15 in gastric carcinoma was 79.8%, higher than that of para-carcinoma tissues (22.2%, P<0.01). The positive expression rate of Akt protein in gastric carcinoma was 80.6%, higher than that of para-carcinoma tissues (16.7%, P<0.01). The expression of MUC15 and Akt was statistically associated with the grades of differentiation, invasion depth, lymphatic metastasis, TNM stage of tumor tissues (P<0.05), and the positive correlation between the two protein expression that appear in the gastric tumor tissue (P=0.001). Univariate survival analysis showed that the over-expression of either MUC15 or Akt was inversely correlated with the survival time (P<0.05 and P<0.01, respectively). Cox multiple regression analysis indicated that patients with over-expression of both MUC15 and Akt had the worst prognoses (HR=3.115, P<0.05). Conclusion:MUC15 may be involved in the occurrence, development, invasion, and metastasis of gastric cancer through the PI3K/Akt cell signaling pathway, and the expression of MUC15 combined with Akt is a powerful predictor for the prognosis of gastric cancer.

Objective To evaluate the efficacy of a type of endotracheal tube of extended with terminal swelling and resistance bending pressure for airway management during mechanical ventilation in children in prone position.Methods Sixty pediatric patients with cerebral palsy of both sexes,aged 3-7 yr,weighing 11-23 kg,of American Society of Anesthesiologists physical status Ⅰ or Ⅱ,scheduled for elective selective functional posterior rhizotomy,were randomly allocated into 2 groups (n =30 each) using a random number table:endotracheal tube of extended with terminal swelling and resistance bending pressure group (group E) and reinforced tracheal tube group (group C).After induction of anesthesia,the type of endotracheal tube of extended with terminal swelling and resistance bending pressure was inserted in group E,and the reinforced endotracheal tube was inserted in group C.The tidal volume,minute ventilation,dynamic lung compliance,arterial oxygen saturation and end-tidal pressure of carbon dioxide in pressurecontrolled ventilation mode were recorded in the two groups.Tube shedding caused by using of the extended tube was recorded during operation.Blood samples were collected from the femoral artery for blood gas analysis.Results Compared with group C,the tidal volume and minute ventilation were significantly increased (P＜0.05),and no significant change was found in dynamic lung compliance,arterial oxygen saturation and end-tidal pressure of carbon dioxide in group E (P＞0.05).Compared with the value before anesthesia,no significant change was found in pH value,arterial oxygen partial pressure and partial pressure of arterial carbon dioxide at the end of operation in the two groups (P＞0.05).In group C,the extended tube wasused in 3 patients,and among the 3 cases,one patient developed tube shedding which was treated immediately.Conclusion The type of endotracheal tube of extended with terminal swelling and resistance bending pressure provides better efficacy than the reinforced endotracheal tube when used for airway management during mechanical ventilation in children in prone position.

OBJECTIVETo perform a retrospective cohort study in order to determine the differences in short-term curative effect of ribavirin in combination with interferon alfa (IFNa)-2a vs. pegylated (Peg)-IFNa-2a in patients with chronic hepatitis C (CHC).

METHODSOne-hundred-and-eighty-eight treatment of the CHC patients who were administered combination therapy of ribavirin with IFNa from 2010 to 2012. One-hundred-and-thirty-three of the patients received the therapy with IFNa-2a and the remaining 55 received Peg-IFNa-2a. Hepatitis C virus (HCV) load and levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were measured at treatment weeks 4, 12, 24, and 48. Adverse reactions were recorded. Differences between the groups were assessed by statistical analysis.

RESULTSThe patients in the Peg-IFNa-2a group and the IFNa-2a group showed no significant difference in sex distribution, age, smoking habits, or drinking habits at baseline (all P more than 0.05). Both antiviral therapies significantly reduced the HCV load and levels of ALT and AST (baseline levels vs. all treatment weeks examined, P less than 0.05); however, the reduction in the HCV load at week 4 was significantly more robust with the Peg-IFNa-2a therapy (2.96 ± 0.66) log10 IU/ ml vs. (3.47 ± 1.42)1og10 IU/ml; F =4.14, P=0.04). The Peg-IFNa-2a group also showed a significant higher rate of rapid virological response (RVR) than the IFNa-2a group (72.72% vs .57.14%; x²=4.37, P=0.04), but there were no statistically significant differences found between the two groups for early virological response rate (EVR), endpoint antiviral treatment virologic response rate (ETR), biochemical response rate, or rate of adverse reactions (all P more than 0.05).

CONCLUSIONRibavirin in combination with Peg-IFNa-2a produces a better RVR than in combination with IFNa-2a .Yet, the EVR, ETR, biochemical response rate, and rate of adverse reactions is similar for the two forms of IFNa-2a. Further studies are required to determine the potential superiority of Peg-IFNa-2a for a long-term curative effect.
