Objective To investigate the effect of combined use of insulin and acarbose on glucose excursion in type 1 diabetic patients.Methods 120 cases were randomly divided into control group and observation group.The control group received preprandial ultra-short effect insulin and long-acting insulin before bedtime while the observation group received acarbose 50 mg added to the medicine taken by the control group.Continuous Glucose Monitoring System (CGMS) was used to watch the blood glucose fluctuations.Data related to blood glucose level,glucose excursions after meals and hypoglycemia at night were compared between patients in the two groups.Results The average blood glucose (9.37 ± 1.70) mmol/L,the largest amplitude of glycemic excursions (LAGE) ( 11.42 ± 2.73 ) mmol/L,hyperglycemia-area under curve 0.89 ± 0.54,mean amplitude of glycemic excursions (MAGE) (5.13 ± 2.23) mmol/L,M-value (18.93 ± 11.43) mmol/L and insulin dosage (42.11 ± 14.42)U/day of observation group were significantly lower than in the control group (P＜0.05 ).Glucose excursions after meals and the times( 0.33 ± 0.50 )/day,the maintenance time (43.75 ± 43.50)/min and low glycemic index ( LBGI ) (0.005 ± 0.002 ) mmol/L of hypoglycemia at night were also significantly lower than in the control group,with statistically significant (P＜0.05) differences.Conclusion The blood glucose fluctuation was significantly improved,with the decrease of insulin dosage while both glucose excursions and hypoglycemia at night reduced in patients with typel diabetes mellitus after the acarbose treatment.We suggested that this program deserve further observation.

OBJECTIVETo investigate the clinical features of postoperative ventilator-associated pneumonia (VAP) after lung surgery.

METHODSOf 104 patients who had undergone lung surgery and been treated with ventilator in our surgical intensive care unit between January 2003 and March 2005, 35 patients met with the criteria of both VAP and postoperative pneumonia (POP), and 41 cases had no evidences of pneumonia. The clinical and laboratory data of all 76 cases were recorded and analyzed by a statistical software package (SPSS).

RESULTSThe diagnosis of postoperative VAP was established clinically in 35 patients (46.1%), and etiologically in 33 cases. Compared to the patients without postoperative VAP, the patients with postoperative VAP had a significantly longer mean interval between intubation and operation [(2.7 +/- 2.9) days vs. (1.6 +/- 1.7) days, P = 0.039], a longer duration of mechanical ventilation [(32.2 +/- 37.7) days vs. (4.2 +/- 2.9) days, P < 0.001], and higher morbidity (20.0% vs. 2.4%, P = 0.013). There was a significant difference in mean duration of mechanical ventilation between the 15 cases of early-onset VAP and 20 cases of late-onset VAP (17 +/- 15 days vs. 43 +/- 46 days, P = 0.042). Among the initially detected pathogen, Staphylococcus aureus remains the most common Gram-positive coccus whereas Acinetobacter Baumannii took the place of Pseudomonas aeruginosa as the top Gram-negative rod.

CONCLUSIONPostoperative VAP after lung surgery has different clinical features from VAP in medical ICU.

OBJECTIVETo evaluate the experience of surgical treatment of pulmonary tuberculosis with endobronchial tuberculosis.

METHODSThe clinical data of 85 patients with pulmonary tuberculosis and endobronchial tuberculosis undergoing surgical resection from 1967 to 2004 were reviewed retrospectively. Forty-five cases were bronchial stenosis. Four cases were tracheal stenosis. Sixteen cases underwent right upper lobectomy. One case underwent right upper and middle lobectomy. Three cases underwent right middle lobectomy. Five cases underwent right middle and lower lobectomy. Two cases underwent right lower lobectomy. Twelve cases underwent left upper lobectomy. Four cases underwent left lower lobectomy. Eight cases were assisted with sleeve lobectomy. Six cases underwent right pneumonectomy (with partial tracheal resection and tracheal reconstruction in 3 cases). Thirty cases underwent left pneumonectomy. One case underwent left lower lobectomy who underwent left upper lobectomy 2 years ago. Four cases were assisted with sleeve pneumonectomy. Three cases underwent tracheal segment resection and tracheal reconstruction. One case underwent left upper bronchial and pulmonary artery sleeve resection. One case underwent biopsy.

RESULTSNo surgical mortality occurred. There was 1 case of bronchopleural fistula and 1 case of empyema in the 35 cases (without sleeve lobectomy) who underwent lobectomy. There were 3 cases of bronchopleural fistula and 4 cases of empyema in the 33 cases (without sleeve pneumonectomy) who underwent pneumonectomy (P < 0.05). There were 5 cases of atelectasis in the 35 cases who underwent lobectomy and 3 cases of atelectasis in the 8 cases who underwent sleeve lobectomy (P < 0.01). In the follow-up of 3 to 10 years, 1 case died due to acute respiratory distress syndrome 7 years postoperatively.

CONCLUSIONSIt is important to resect all the tissue which has been infected. With the routine anti-tuberculosis chemotherapy during the perioperative period, the effect of surgical treatment is superior to others. Fewer pneumonectomy is also important.

OBJECTIVETo compare video-assisted thoracic surgery (VATS) and open thoracotomy (OT) on acute inflammatory responses and immunosuppression after lobectomy for early non-small cell lung cancer (NSCLC).

METHODSPresent prospective randomized study. OT or VATS lobectomy was performed in patients who met enter criteria and clinical data was collected. Plasma concentration of IL-6, IL-8 and IL-10 were measured before surgery and at postoperative day (POD) 1 and POD 3. There were 271 patients underwent lobectomy for early NSCLC, including of 133 patients in group VATS and 138 patients in group OT from January 2007 to June 2008. There were 132 males and 139 females, aging from 19 ∼ 70 years with a mean of (56 ± 8) years.

RESULTSCompared with OT group, shorter postoperative hospital stay [(8.2 ± 2.5) d vs. (9.8 ± 6.2) d, P = 0.03], lower morbidity rate (11.3% vs. 21.7%, P = 0.02) and lower increase of plasma concentration of IL-6 at POD 1 [(35 ± 25)% vs. (65 ± 43)%, P = 0.00], IL-6 at POD 3 [(14 ± 22)% vs. (55 ± 44)%, P = 0.00] and IL-10 at POD 1 [(25 ± 20)% vs. (43 ± 35)%, P = 0.00] were observed in patients of VATS group.

CONCLUSIONVATS lobectomy for early NSCLC is associated with less acute inflammatory responses and less immunosuppression when compared with OT.

Objective To compare insulin secretion and action with impaired fasting glucosc (IFG),impaircd glucose tolerance (IGT) and combined glucose intolerance (CGI,IFG and IGT) between Han and Uygur populations living in Xinjiang.Methods A multicenter cross-section survey (The Third Diabetes Epidemiological Survey in China) was conductcd in Xinjiang from 2007 to 2008 including 2203 subjects (Han 1118,Uygur 1085) underwent an oral glucosc test (OGTT).Homeostasis model assessment on insulin resistance (HOMA-IR) and β cell function (HOMA-β)were calculated.The ratio of incrcmcntal insulin(Δ130 ) and glucose (ΔG30)response was used to evaluate the early insulin secretion.ΔI30/ΔG30/HOMA-IR was used to evaluate the glucosc disposition index (DI).Results There were differences noticed regarding the waist circumstances (WC),body mass index (BMI),lipids,0 and 120 min insulin lcvcls in different glucose tolerance status between the Hans and Uygurs.Data related to NGT,IFG,CGI,WC from the Uygurs was significantly diffcrcnt from that of the Hans (P＜0.01),while the NGT,IFG,IGT and 120-minute plasna insulin levels of the Hans were significantly different from that of the Uygurs (P＜0.01).HOMA-IR and HOMA-β in Hans were significantly different from those of the Uygurs (P＜0.01).There were significant differences noticed on data reoated to Δ130/ΔG30,and DI among the two populations with different ethnicities.Conclusion Regarding the regulation of impaired glucose,the insulin resistance among the Hans was significantly different from that of the Uygurs,while there seemed to be a compensatory secretion of pancreatic β cells which played the role of maintaining blood glucose homeostasis.

OBJECTIVETo study the effectiveness of waist circumference cut-off values in predicting the prevalence of metabolic syndrome (MetS) and risk factors in adults in China.

METHODSA cross-sectional survey was condcuted in 14 provinces (autonomous region, municipality) in China. A total of 47,325 adults aged⋝20 years were selected by multistage stratified sampling, and questionnaire survey and physical and clinical examination were conducted among them. MetS was defined according to the International Diabetes Federation (IDF) criteria and modified IDF criteria.

RESULTSThe age-standardized prevalence of MetS was 24.2% (22.1% in men and 25.8% in women) and 19.5% (22.1% in men and 18.0% in women) according to the IDF criteria and modified IDF criteria respectively. The age-standardized prevalence of pre-MetS was 8.1% (8.6% in men and 7.8% in women) according to the modified IDF criteria. The prevalence of MetS was higher in urban residents than rural residents and in northern China residents than in southern China residents. The prevalence of central obesity was about 30% in both men and women according to the ethnicity-specific cut-off values of waist circumference for central obesity (90 cm for men and 85 cm for women). Multivariate regression analysis revealed no significant difference in risk factors between the two MetS definitions.

CONCLUSIONUsing both the modified IDF criteria and ethnicity-specific cut-off values of waist circumference can provide more useful information about the prevalence of MetS in China. Conclusion Using both the modified IDF criteria and ethnicity-specific cut-off values of waist circumference can provide more useful information about the prevalence of MetS in China.
