Objective To summarize the perioperational nursing strategies for patients undergoing mandibular defect repair by forearm flap composite fibula flap.Methods From January 2009 to December 2012,9 patients with mandibular defect and soft tissue defects after resection of malignant tumors received fibula flap and forearm flap.Before operation,the patient received psychological education and the preparation of donor flap and receptor area together with oral preparation was performed.After operation,the vital signs and blood circulation in the flap were observed.Results The fibula and forearm flaps in 8 patients survived.The fibula flap in one patient survived while the forearm flap developed with vascular crisis.The success rate for the transplanted flap was 89.9%. Conclusion The perioperative nursing strategies are key to increase survival rate of flaps and the success rate of operation.

Objective To study the combination effects of telmisartan and pioglitazone on the expression of heparanases (HPA) and podocin in the kidney of diabetic nephropathy (DN) rats and its possible mechanism. Methods DN model rats were established by intraperitoneal injection with STZ for 12 weeks. All the DN rats were randomly divided into telmisartan group (T group), pioglitazone group (P group), combination of telmisartan and pioglitazone group (L group), and DN group (D group). Healthy rats were chosen as healthy control group(N group). After garage with drugs for 12 weeks, 24-h urinary protein and serum biochemical indicators were examined. RT-PCR and immunohistochemistry methods were applied to detect the mRNA and protein expression of HPA and podocin. Results Compared with T group and P group, 24-h urinary protein of L group was markedly decreased(P<0.05). Compared with the N group, the level of fasting blood glucose, relative renal weight, BUN and Scr in other 4 groups were markedly increased (P<0.05). Compared with T group and P group, the Scr level and the expression of HPA mRNA and protein in L group was markedly decreased (P<0.05), and the protein and mRNA expression of podoein in L group was markedly increased (P<0.05). Conclusion Combination of telmisartan and pioglitazone can down-regulate the mRNA and protein expression of HPA of glomerular basement membrane and up-regulate the protein expression of podocin of podocyte in DN rats, which may ameliorate the proteinuria.

OBJECTIVETo investigate the correlation between smoking status and carotid plaque in rural population residing in Eastern part of China.

METHODSBetween July and September of 2013, an epidemiological survey was carried out in residents aged 40 or above men who were enrolled randomly in rural areas of Anqing, Anhui province and Lianyungang, Jiangsu province. The data on epidemiological characteristics including smoking status, physical examination were collected using standardized protocol, and carotid ultrasonography was applied to examine the incidence of carotid plaque among never smokers, former smokers and current smokers. Logistic regress analysis was performed to determine the effect of smoking on carotid plaque.

RESULTSIn the study, a total of 625 male participants were included in the study. 51.4% (321 cases) were current smokers, 21.3% (133 cases) were former smokers, and 27.4% (171 cases) were never smokers. 32.0% (200/625) had carotid plaque. The incidence of carotid plaques was significantly higher in current smokers (35.2%, 113/321) than that in never smokers(23.4%,40/171) (χ(2) = 7.26, P = 0.007) and the incidence in former smokers (35.3%, 47/133) was also higher than that in never smokers (23.4%, 40/171) (χ(2) = 5.23, P = 0.022). Multiple logistic regression analysis showed that current cigarette smoking is significantly associated with the increased risk of carotid plaque (OR = 1.84, 95% CI: 1.13-2.98, P = 0.014) in comparison with never smokers, and there was an interaction between current smoking and age in association with carotid plaque. Compared with the young (≤60 years old) and never smoking group (8%, 3/40), prevalence of carotid plaque among the elderly (>70 years old) and smoking group (55%, 31/56) was significantly higher (OR = 8.06, 95% CI: 2.07-31.45) after adjusting for age, systolic blood pressure, diastolic blood pressure, blood glucose, total cholesterol, triglyceride high-density lipoprotein, body mass index, drinking and regional differences.

CONCLUSIONIt found that cigarette smoking was associated with increased risk of carotid plaque in rural elderly population residing in Eastern part of China.

We aimed to investigate the relationship of dietary zinc intake with new-onset hypertension among Chinese adults. A total of 12,177 participants who were free of hypertension at baseline from the China Health and Nutrition Survey were included. Dietary intake was assessed by three consecutive 24-h dietary recalls combined with a household food inventory. Participants with systolic blood pressure ≽ 140 mmHg or diastolic blood pressure ≽ 90 mmHg or diagnosed by a physician or under antihypertensive treatment during the follow-up were defined as having new-onset hypertension. During a median follow-up duration of 6.1 years, 4269 participants developed new-onset hypertension. Overall, the association between dietary zinc intake and new-onset hypertension followed a J-shape (P for non-linearity < 0.001). The risk of new-onset hypertension significantly decreased with the increment of dietary zinc intake (per mg/day: hazard ratio (HR) 0.93; 95% confidence interval (CI) 0.88-0.98) in participants with zinc intake < 10.9 mg/day, and increased with the increment of zinc intake (per mg/day: HR 1.14; 95% CI 1.11-1.16) in participants with zinc intake ≽ 10.9 mg/day. In conclusion, there was a J-shaped association between dietary zinc intake and new-onset hypertension in general Chinese adults, with an inflection point at about 10.9 mg/day.
