Objective To study the nursing of bedsore prevention in patients with unstable pelvic fracture. Methods Bedsore forewarning risk assessment went on in 39 patients with unstable pelvic fracture by Braden scoring method. Results No bedsore was observed in these 39 patients with unstable pelvic fracture.The nursing result turned out to be satisfactory. Conclusions The incidence rate of bed-sore can be degraded in patients with unstable pelvic fracture by forewarning risk assessment with Braden scoring method and early nursing intervention.

Objective To evaluate the clinical value of ~(99m)Tc-MAA imaging in patients with lower extremital posttraumatosis and postoperation(LEPP).Methods 21 LEPP patients with clinical highly suspected acute pulmonary embolism(APE) underwent ~(99m)Tc-MAA veins imaging and pulmonary perfusion imaging(PPI).Vena caval filters were inserted and thrombolysis were given in patients with big area APE and/or iliofemoral vein thrombosis indicated by ~(99m)Tc-MAA imaging.Thrombolysis was given in patients with small area APE and/or subpopliteal vein thrombosis.PPI was reexamined after 2～4weeks` treatment.The lung segments with 100% lack of perfusion were marked 3,those with 25%～75% were marked 2,those with less than 25% were marked 1 and normal was marked 0.The therapeutic results were assessed using this marking system.Results There were 13 patients with big area APE,8 with small area APE,14 with iliofemoral vein thrombosis,and 7 with subpopliteal vein thrombosis.2 cases(9.5%) died before thromobolytic therapy.The marks were significant different before(10.2?3.8) and after(2.8?1.4) treatment(t=7.75,P

Objective:To evaluate the importance of 3D-CTA with volume rendering for the diagnosis of multiple intracranial aneurysms. Methods: Axial source images were obtained by helical CT scanning and reconstruction of 3D-CTA images was done by volume rendering technique in conjunction with multiplanar reformation. Results: In the past one year,there were 10 patients diagnosed as having multiple intracranial aneurysms by 3D-CTA and altogether 24 aneurysms were visualized,including 10 small aneurysms(≤5mm.Three dimensional CT angiography with volume rendering demonstrated aneurysms very well and provided useful information concerning the site,shape,size and spatial relationship with the surrounding vessels and bone anatomy. Conclusion: Three-dimensional CT angiography with volume rendering is a quick,reliable,and relatively noninvasive method for diagnosing multiple intracranial aneurysms.It delineates detailed aneurysmal morphology,and provides useful information for planning microsurgical approaches.

Objective To investigate ACEI ( benazepril ) and tranilast exert renoprotective properties in diabetic nephropathy( DN) through the inhibition of thioredoxin( Trx) . Methods Forty male SD rats were randomly divided into normal control group,model control group,tranilast group and benazepril group (n=10 each).Normal control group was fed with normal diet. Other groups were fed with high-glucose high-fat diet to make DN models. Rats in model control, tranilast, and benazepril groups were fed with normal diet,400 mg??kg-1??d-1 tranilast plus normal diet,and 10 mg??kg-1??d-1 benazepril plus normal diet,respectively,via oral gavage for 12 weeks.The 24-hour proteinuria,blood glucose(BG),blood urea nitrogen (BUN),serum creatinine ( Scr) and renal pathology changes were detected. Expression of Trx was measured by Western-blot. Results The 24 h urine protein, BG, BUN, Scr, kidney/body weight, and glomerular sclerosis index were significantly decreased in tranilast group and benazepril group,as compaired with model control group ( P<0.05) ,but there was no statistical difference between the two drug groups (P>0.05).Both tranilast and benazepril can reduce renal pathological changes,and can increase the expression of Trx of DN rats, but benazepril had a more significant effect on increasing Trx expression. Conclusion Both tranilast and benazepril have renoprotective function in DN, and benazepril is more effective than tranilast in delaying the progression of diabetic nephropathy by increasing Trx expression and decreasomg oxidative stress.

Objective:This study aims to provide scientific evidence for prevention and treatment of iodine deficiency disorders through monitoring the iodine nutrition status of children and pregnant women in Shaanxi Province.Methods:Totally 110 counties (cities, districts) in Shaanxi Province in 2019 were surveyed. Each of the counties (cities, districts) was further divided into five sampled regions along five different geographic directions: east, west, south, north and middle. From each region, one town was selected and then one primary school was selected from each town. Finally, there were a total of 42 non-boarding students aged 8 - 10 years old (age and gender balanced) selected from each school, who would be tested household salt iodine's level and urinary iodine's level. Also, we did the same test for 21 pregnant women who were selected from each town randomly. Additionally, we examined the children's thyroid by B-scan ultrasonograph in 39 counties (cities, districts).Results:A total of 23 101 salt and urine samples were collected from children aged 8 - 10 years old, the average of salt iodine content of the children' family was (24.07 ± 3.71) mg/kg; the consumption rate of qualified iodized salt was 97.55% (22 536/23 101); the median urinary iodine was 211.68 μg/L; and the thyroid goiter rate (TGR) was 1.50% (123/8 191). A total of 11 555 salt and urine samples from pregnant women were collected, the salt iodine content was (24.05 ± 3.66) mg/kg; and the consumption rate of qualified iodized salt was 97.57% (11 274/11 555); the median urinary iodine was 182.74 μg/L.Conclusions:In 2019, the iodine nutrition of children in Shaanxi Province is in the super appropriate level, and the iodine nutrition of pregnant women is appropriate. The iodine content of edible salt can be adjusted. It is suggested that pregnant women should be supplied special iodized salt.

Objective:To evaluated the options in selection of surgical procedures for treatment of the patients suffering from diabetic feet with chronic refractory wounds.Methods:From January 2020 to June 2021, 23 patients with diabetic feet complicated with refractory wounds were treated in Department of Hand Surgery, Shunde Heping Surgical Hospital. The patients were 15 males and 8 females, aged 51-86 years old and with an average age of 65 years old. All the patients had Type-II diabetes for over 5 - 22 years. Average blood glucose of the patients was found at 15.6 mmol/L on admission. Free anterolateral thigh perforator flaps (ALTPF) were used for reconstruction of the wound of diabetic feet in 19 patients, 2 patients received vascular bypass surgery and 2 had amputations. Regular outpatient follow-up were conduct on all patients after surgery.Results:Follow-up time lasted for 8 to 30 months, 12 months in average. At the last follow-up, the donor and recipient sites healed well in the 19 patients who received flap reconstruction, without an infection, necrosis and wound recurrence. Pains were significantly relieved after the surgery in the 2 patients who received vascular bypass surgery, and wounds all healed well after symptomatic treatment and dressing change without recurrence of wounds at the last follow-up. Average Maryland score of foot function was 84 for the patients who had limb salvage, and 2 patients were in excellent and 19 in good at the last follow-up. The 2 patients who had amputation successfully survived through the perioperative period, and the wounds healed well at the last follow-up.Conclusion:The treatment is complicated in the patient suffering from diabetic foot with chronic refractory wounds due to factors such as advanced age, co-existing and complicated underlying diseases together with the complex wounds. Most patients can achieve good prognosis in wound treatment of free flap transfer or vascular bypass surgery. However, a limb salvage is recommended with caution for the patients who have severe infections and dry gangrene.
