Objective:To study quality of life and life satisfaction among the elderly population dwelling in Ji'nan. Method:1386 elderly people were interviewed with“the Short-Form 36 Health Survey Scale”by the investigators who were trained in advance.Results:The prevalence rate of chronic diseases was 65.1%. The main influencing factors of life satisfaction were mental health condition, family harmony, marriage condition, chronic diseases, and income. The main influencing factors of life quality are life satisfaction, chronic diseases, mental health condition, activities of daily life, family harmony, and income.Conclusion:Life satisfaction is closely associated with life quality of elderly people. The physical, psychological, social and economic conditions have significant effect on life quality of elderly people.

Objective To analyze the risk factors of early renal damage in children with Henoch Schonlein purpura(HSP).Methods The clinical data of 196 children with HSP admitted to our hospital from April 2012 to January 2016 were analyzed retrospectively.They were divided into the renal damage group and non-renal damage group within 90 d after confirmed diagnosis.The related clinical data such as serum immunoglobulin and urinary microalbumin were compared between the two groups,and the risk factors of early renal damage in children with HSP were screened.Results There were significant differences between the two groups on age,joint symptoms,recurrent purpura,persistent rash,gastrointestinal bleeding and abdominal pain(with χ2 or t of 11.345,16.223,11.275,43.211,12.592,17.771,P<0.05).The white blood cell count,platelet count,immunoglobulin A(IgA) level and urinary albumin level also showed significant differences between the two groups(t=33.750,60.442,9.451,8.458,P<0.05).The multivariate regression analysis showed that the independent risk factors for early renal damage in children with HSP included age(OR=2.703),recurrent purpura(OR=2.721),persistent skin rash(OR=1.782),gastrointestinal bleeding(OR=11.472),abdominal pain(OR=2.046),IgA level(OR=1.221) and urine microalbumin(OR=3.214).Conclusion Age,recurrent purpura,persistent skin rash,gastrointestinal bleeding,abdominal pain,IgA level and urine microalbumin are closely related to early renal damage in children with HSP.

OBJECTIVE: To observe the time-course expression of zonula occludens-1 (ZO-1) in cerebral cortex after traumatic brain injury (TBI). METHODS: The TBI model of mouse was established. The mice were divided in 1 h, 3 h, 6 h, 12 h, 24 h, 3 d, 7 d after TBI, sham and control groups. The permeability of the blood brain barrier was evaluated by measuring the extravasation of Evans blue (EB) dye. The expression of ZO-1 in cerebral cortex in the injured area was detected by Western blotting and immunohistochemistry. RESULTS: The extravasation of EB dye of injured cortex gradually increased from 1 h, peaked at 1-3 d and approximately decreased to normal at 7 d after TBI. Western blotting revealed that the expression of ZO-1 gradually decreased after 1 h, was at the lowest at 1-3 d, and then significantly increased after 7 d but was still lower than that of normal and sham groups. The result of immunohistochemistry showed that ZO-1 had strong expression in vessel of normal cortex, gradually decreased after TBI, and almost disappeared at 3 d after TBI and gradually recovered to normal level later. CONCLUSION The expression of ZO-1 in the injured cortex after TBI initially decreases and then increases. The negative correlation between ZO-1 expression and EB extravasation after TBI could be used as a new indicator for wound age estimation.

Objective:To summarize the perioperative nursing experience of a patient with hemophilia arthritis complicated with hepatitis C undergoing unilateral hip and knee arthroplasty at the same time.Methods:In August 2018, a patient with hemophilic arthritis complicated with hepatitis C was admitted to the first hospital of Lanzhou University. Preparations for health education, functional exercises, examination and evaluation before operation was made. Unilateral hip and knee arthroplasty were performed at the same time, strengthen the management of incisions and catheters after the operation, actively prevent complications, and guide patients to perform functional rehabilitation exercises under the conditions of good pain management and safe coagulation factor activity; pay attention to the nursing of coagulation factor replacement treatment in the whole perioperative period.Results:After careful nursing, no serious complications occurred during the patient's hospitalization, and the position and force line of the prosthesis were satisfactory by imaging examination before discharge.Conclusion:The perioperative care of this patient proved that the above-mentioned nursing measures are effective for hemophilic arthritis patients with hepatitis C undergoing unilateral hip and knee arthroplasty at the same time.

OBJECTIVE To study the epidemiology of the drug-resistant genes in meticillin-resistant coagulase negative staphylococcus(MRCNS).METHODS mecA,aac(6′)/aph(2″) and aph(3′)-Ⅲgenes of aminoglycoside-modifying enzyme(AME) and ermA/B/C genes of erythromycin methyltransferase were detected by polymerase chain reaction(PCR) from 40 MRCNS strains.RESULTS Thirty-nine strains carried mecA gene,32 strains with aac(6′)/aph(2″) gene,15 strains with aph(3′)-Ⅲ gene,30 strains with ermA/B/C gene and 2 strains with tetM gene in 40 MRCNS strains.CONCLUSIONS About 65% MRCNS strains carry mecA,aac(6′)/aph(2″),/aph(3′)-Ⅲ and ermA/B/C genes at the same time.

Objective To study the effects of mild hypothermia on nervous cell apoptosis and activity of Caspase - 3 after hypoxia -ischemia brain damage (HIBD) in neonatal rats. Methods Seven - day SD rats were divided into sham operation group,normothermia HIBD group (HIBD group) and mild hypothermia HIBD group(mild hypothermia group). In HIBD group,the left carotid of rats was ligated and animals were exposed to 8% oxygen for 2 h.and in mild hypothermia group,hypothermia of 31 - 32 1C lasting 8 hours was used just after HIBD. L sing methods of TUNEL and AC - DEVI) - AMC, the apoptotic cell rate and Caspase - 3 activity level were determined in sham operated group, HIBD group and mild hypothermia group separatively. Results The apoptotic cell rate and Caspase - 3 activity level were significantly lower in sham - operated group and mild hypothermia group than those in HIBD group. Conclusion One of the mechanisms of brain protection by mild hypothermia may be contributed to the decrease of neural cell apoptosis and the activity level of Caspase 3 HIBD.

Objective To investigate the usefulness of the helical CT in demonstrating the abnormal blood vessels of intralobar pulmonary sequestration. Methods In fourteen patients with suspicion of pulmonary sequestration, contrast enhanced helical CT was performed. Clinical presentation included hemoptysis (2), pulmonary infection (8), and asymptomatic (4). Fourteen cases underwent helical CT examination with different scanner and scan parameters. Five CT angiography (CTA) studies were performed by single-section helical CT scanner (Hispeed Advantage, GE, USA) with 3 mm slide thickness, 4.5 mm/s table speed and 1.5 mm reconstruction index. Three CTA studies were done by multisection CT scanner (MX8000 four-slice CT, Marconi, USA) with a collimation of 2.5 mm, resulting in an effective slice width of 3.2 mm. Non-ionic contrast media (iodine 300 mg I/ml) was administered at a rate of 2.5 ml/s via the antecubital vein. The optimal opacification of the upper abdominal aorta were achieved through the use of the Smart Prep (Hispeed Advantage) program or by using the Boluspro ultra (MX8000). Three-dimensional reconstruction was performed with the workstation. Five cases were scanned by using single-section helical CT scanner with 5 mm collimated section and 5 mm/s table speed. And in one patient CT scan was performed with 10 mm section thickness and 10 mm/s table speed. Results CT findings were pulmonary mass (11) and well-defined nodules (3). The lesions were located in right lower lobe (2) and left lower lobe (12). Helical CT identified the aberrant arterial supply in all cases. The origin of the anomalous artery was the descending thoracic aorta (2), upper abdominal aorta (11) and splenic artery (1). These findings were confirmed by operation. Conclusion The combination of axial and 3D images in helical CT, especially the multislice helical CT, is helpful in the assessment of the abnormal blood vessels of intralobar pulmonary sequestration. It can substitute to the angiography in the diagnosis of pulmonary sequestration.
