BACKGROUND: With the increase of senile population, it needs to further improve their mental health when improving their physical health. To study the depressive status of retired elderly people in order to provide basis for effective community nursing intervention.OBJECTIVE: To investigate and analyze the depression incidence among retired elderly people and conducted correlative factors analysis in order to improve the nursing service to aged people's mental health.DESIGN: Cross-sectional sampling study towards retired senior people.SETTING: Nursing department of a medical college.PARTICIPANTS: This study was completed in Nursing Department of North China Coal Medical College during September to December 2002. It conducted questionnaire survey to 1 000 retired people in Tangshan city by family visit. There were 574 male and 426 female who aged from 60 to 88years old with mean age of 67 years.METHODS: To adopt geriatric depression scale and general condition questionnaire investigation to individuals.MAIN OUTCOME MEASURES: Depression scale score, depression incidence and frequency of correlative factors RESULTS: Mild depression accounts for 17.2% while moderate and severe depression account for 5% among retired elderly people. There is close relationship between factors such as retired veterans, female, low education,lack of social support, empty life, lack of exercise and poor self-assessed health and depression incidence(x2 = 9.80 - 175.93, P ＜ 0. 05).CONCLUSION: The incidence of senile depression among retired elderly people is pretty high so that it is important to pay attention to mental care towards retried people when doing community nursing, especially to divorced, widowed, female and low educated retired people.

Objective To investigate the protective effect of the ethanol extract of vacciniuin bracteatum thumb leaf on acute liver injury induced by CC14 in mice. Methods Sixty mice were allocated into 6 groups randomly, respectively as the normal control group,the model group,the positive control group,the ethanol extract low,middle and high dose group. Each group had 10 mice. Acute hepatic injury model of mice was made by using CC14. The level of ALT, AST in blood serum and SOD,MDA in hepatic tissue were observed. The hepatic tissue was HE-stained conventionally and observed. Results Acute liver injury in mice could be successfully induced by CC14 ,as demonstrated by increased serum ALT, AST levels and severe histological observations. Pretreatment with the ethanol extract of vaccinium bracteatum thumb leaf indicated its potent protective effects on acute liver injury, as demonstrated by a significant decrease in ALT, AST and MDA. Conclusion The ethanol extract of vaccinium bracteatum thumb leaf had an obviously protective effect on acute liver injury induced by CC14, which could be due to its antioxidative stress effect.

BACKGROUND: Homocysteine(HCY) is emerging as an independent risk factor for atherosclerosis. Its damage to the structure and function of endothelial cell(EC) is seemingly an important mechanism that leads to atherosclerosis.OBJECTIVE: To investigate the effect of HCY on fibrinolysis in elderly patients with coronary heart disease(CHD).DESIGN: A case-controlled study based on CHD patients and normal people as control group.SETTING: Department of general internal medicine and department of cardiology in a university hospital.PARTICIPANTS: The study was completed in the Department of Gerontology Internal Medicine and Department of Cardiology, Beijing Chaoyang Hospital, Capital University of Medical Science. Altogether 177 inpatients and outpatients from this hospital during December 2001 to August 2003 were selected and divided into three groups according to the results of coronary angiography(CAG): CHD group( n = 91 ) with 50 males and 41 females with the mean age of(66 ± 6) years, negative CAG group( n = 86) with 43 males and 43 females with the mean age of(60 ± 6) years, and normal control group( n = 85) with 43 healthy males and 42 healthy females with the mean age of(55± 5) years.METHODS: Peripheral blood samples were collected. ELISA double antibody method was applied to test tissue-type plasminogen activator(t-PA), plasminogen activator inhibitor-1 (PAI-1) and yon Willebrand factor(vWF). HCY was assayed with EIA method and the ratio of PAI-1 to t-PA was calculated.MAIN OUTCOME MEASURES: HCY level, t-PA, PAI-1 and vWF activities, and the ratio of PAI-1 to t-PA.RESULTS: The levels of HCY, PAI-1, PAI-1/t-PA and vWF in CHD group were significantly higher than those in negative CAG group and normal control group( P ＜ 0.01 ); however, the level of t-PA was significantly lower than that in control group( P ＜ 0. 01) . HCY was positively correlated with PAI-1,PAI-1 / t-PA and vWF, while it was negatively correlated with t-PA.CONCLUSION: The increase of serum HCY is accompanied with fibrinolytic dysfunction. HCY is positively correlated with PAI-1 and vWF but negatively correlated with t-PA. Therefore, HCY is a predictor for early coronary lesions,and can provide related laboratory data for the primary prevention and early treatment of CHD.

Objective To investigate the clinical value of multiband mucosectomy (MBM) for the treatment of early esophageal cancer and precancerous lesions.Methods The clinical data of 43 patients with early esophageal cancer or precancerous lesions (including 13 cases of early esophageal cancer and 30 cases of precancerous lesion) who were admitted to the Tengzhou Central People's Hospital from January 2010 to January 2011 were retrospectively analyzed.A total of 51 lesions were confirmed by preoperative endoscopy and mucosal biopsy,and then were treated by MBM.Results A total of 52 MBM procedures were carried out,and 180 lesions were resected.The sizes of the lesions ranged from 10 mm × 8 mm to 25 mm × 23 mm,and the mean operation time was (37 ± 5)minutes.The complete resection rate was 92.2％ (47/51).The submucosal layer of 1 patient was invaded by squamous cell carcinoma postoperatively,and the patient was treated by operation;1 patient wth squamous epithelium carcinoma was treated by radiotherapy at 2 weeks after MBM ; the other 2 lesions were treated by argon plasma coagulation (APC).Four lesions with bleeding were detected during 52 MBM procedures,and no esophageal perforation was detected during MBM.Early complications consisted of delayed bleeding (1 patient,cured by APC) and slight esophageal stenosis (1 patient,recovered at postoperative month 6).The accurate rate of pathological examinations was 51.0％ (26/51).Forty-three patients were followed up for 1 year,3 patients with tumor recurrence were treated by MBM or APC.No death occurred during the followup.Conclusion MBM is a safe and effective technique for the treatment of early esophageal cancer and precancerous lesions.

OBJECTIVE:To investigate the effects of different doses of sufentanil citrate on hemodynamic indexes and stress response indexes of Crouzon syndrome children with craniofacial reconstruction. METHODS:60 cases of Crouzon syndrome under-going craniofacial reconstruction were selected from our hospital during Jan. 2010-Jan. 2016,and then randomly divided into group A,group B and group C,with 20 cases in each group. 3 groups were given pump injection of Propofol injection 4-8 mg/(kg·h)for anesthesia induction+Sufentanil citrate injection [group A 0.3 μg/(kg·h),pump injection;group B 0.6 μg/(kg·h),pump injection;group C 1.0 μg/kg,iv,0.5 h/time] for anesthesia maintenance, Cisatracurium besilate for injection 0.1 mg/kg,iv,every 40 min, drug withdrawal 5 min before the end of surgery. The hemodynamic indexes(MAP,HR)and stress response indexes(ACTH,cor-tisol)were observed in 3 groups at different time points as well as the occurrence of ADR. RESULTS:MAP levels of group C at 5 min after skin incision,1 h after operation and immediately at the end of surgery were significantly higher than before anesthesia, while those of group B were significantly higher than group C at same time points. HR of group A at 1 h after surgery and that of group B at 5 min after skin incision and 1 h after surgery were significantly higher than before anesthesias;HR of group B at 1 h after surgery was significantly lower than that of group A,and its HR at 5 min after skin incision and 1 h after surgery were signifi-cantly lower than those of group C. ACTH levels of 3 groups at 5 min after skin incision,1 h after surgery and immediately after the end of surgery were significantly higher than before anesthesia. ACTH levels of group B at 5 min after skin incision,1 h after surgery and immediately after the end of surgery were significantly lower than those of group A and C,and the group A was signifi-cantly lower than the group C at same time points. Cortisol levels of group A at 1 h after surgery,and those of group C at 5 min af-ter skin incision,1 h after surgery and immediately after the end of surgery were significantly higher than before anesthesia. Corti-sol levels of group B at 1 h after surgery were significantly lower than those of group A;cortisol levels of group A at 5 min after skin incision and immediately after the end of surgery and those of group B at 5 min after skin incision,1 h after surgery and imme-diately after the end of surgery were all significantly lower than those of group C. There were statistical significance all above(P<0.05). No obvious ADR was found in 3 groups. CONCLU-SIONS:Pump injection of sufentanil citrate 0.6 μg/(kg·h) can maintain analgesic effect of Crouzon syndrome children with craniofacial reconstruction,can keep hemodynamics sta-ble and effectively inhibit stress response during surgery with good safety.
