BACKGROUND: There are different reports on the comorbidity rates of anxiety and depression. In the pathopsychology of depression, it is unclear for the relationship between coping styles and personality in depressive patient accompanied with anxiety disorders.OBJECTIVE: To analyze the relationship between coping styles and personality in depressive patient with anxious disorders.DESIGN: A case-control study.SETTTNG: Second Xiangya Hospital of Central South University; Hunan Brain Hospital.PARTICIPANTS: Eighty-eight patients with depression were selected from the Second Xiangya Hospital of Central South University and Hunan Brain Hospital from June 2002 to January 2003. Ninety subjects were selected as normal control group from the employees or their family members, health volunteers in the Second Xiangya Hospital of Central South University and Sun Yat-sen University.METHODS: All the subjects were surveyed with self-rating depression scale (SDS), self-rating anxiety scale (SAS), coping style questionnaire and Eysenck personality questionnaire (EPQ).MATN OUTCOME MEASURES: ① Comparison of the scores of SDS, SAS, coping styles questionnaire and EPQ between the depressive group and normal control group; ② Comparison of the scores of SDS, SAS, coping styles questionnaire and EPQ between the depressive patients with and without anxious symptoms. ③ Pearson correlation analysis and stepwise regression analysis of all the indexes in the depressive group.RESULTS: ① All the 178 subjects were involved in the final analysis of results. ① The total scores of SDS and SAS, the scores of psychoticism and neuroticism of EPQ in the depressive group were significantly higher than those in the normal control group, but the score of introversion-extraversion of EPQ and passive coping style were lower than those in the control group. ② The total scores of SDS and SAS, the scores of psychoticism and neuroticism of EPQ were obviously higher but the score of active coping style was lower in the depressive patients with anxious symptoms than in those without anxious symptoms. ③ The correlation analysis and stepwise regression analysis suggested that the severity of depressive symptom was significantly related with SAS, introversion-extraversion dimension of EPQ and passive coping style.CONCLUSION: ① Depressive patients suffer from obvious depressive and anxious symptoms and psychoticism, and they inclined to introversion and emotional instability, and adopt less active coping style. ② Depressive patients with anxious symptoms suffer from more serious depressive symptoms, psychoticism and neuroticism, and they adopt active passive coping style. ③ Less adoption of active coping style can be brought into the dimension of introversion-extraversion in personality trait.

Objective To study the clinical features and pathology of renal damage in patients with MPA. Method The clinical pathological changes of 23 MPA patients were analyzed and the patients with positive ANCA were compared with those with negative ANCA. Results Most MPA patients were senile and male with the symptoms of lung damage, pleuritis, arthritis and myalgia as well as extrarenal symptoms such as fever, weight-loss, and anorexia. 65.2% of the patients were ANCA (+). Symptoms of renal function damage were hematuria and proteinuria, which could be found in all the patients. Different degree of renal damage could be detected. Glomerular cresent formation, which were mostly fibrous, could be found in all of the 23 patients. Half of the patients have tuft necrosis and interstitial vessel vasculitis. Conclusion MPA patients often have extrarenal symptoms besides renal function damage. Patients with positive ANCA differs from patients with negative ANCA in both clinical manifestation and kidney pathology.

Objective To investigate the effect of persistent hypoglycemia on the cerebral oxidative stress and matrix metalloproteinase-2 (MMP-2) activity of newborn rats and to explore the potential mechanism of hypoglycemia-induced brain injury of newborn.MethodsSeven-day-old rats were injected insulin subcutaneously to induce persistent hypoglycemia.Cerebral cortex,hippocampus and thalamus were collected after 36 hours' observation and stored in -80 ℃.Glutathione (GSH)and glutathione disulfide (GSSG) were detected by commercial kit and GSSG/GSH was calculated.MMP-2 activity was detected by gelatin zymography. The data were analyzed by t test,one or two-wayanalysis of variance and Pearson correlation analysis.Six rats were set as the normal glucose group. ResultsThirty-six hours after induction of hypoglycemia, the cerebral GSSG and GSSG/GSH of hypoglycemic pups elevated about 1.5 times higher than those of control group [GSSG:(15.89 ± 5.46) vs (6.15 ± 3.42) mg/g protein,t =3.704,P =0.004; GSSG/GSH:(5.58± 1.79) % vs (2.79±1.76) %,t =2.712,P=0.022].The GSSG and GSSG/GSH in thalamus of hypoglycemia were significantly higher than those of control [GSSG:(15.93 ± 5.75) mg/g protein vs (5.03±5.14)mg/g protein,P<0.05; GSSG/GSH:(6.50±3.25) % vs (2.41±3.12) %,P<0.05],whereas there were no significant differences in the cortex ard hippocampus.The total MMP-2 activity of hypoglycemic animals (2.22±0.59) was significantly higher than that of control (1.21± 0.17)(t=4.064,P=0.002),and significant differences were found between the two groups in cortex (2.14 ± 0.5 vs 1.17± 0.27),hippocampus (2.31± 0.72 vs 1.22 ± 0.37) and thalamus (2.22±0.68 vs 1.24±0.18) with all P<0.01].The activity of MMP-2 was positively related to GSSG (r=0.575,P=0.0002) and GSSG/GSH (r=0.484,P=0.0003).ConclusionsOxidative stress might play an important role in the persistent hypoglycemia induced brain injury of 7-day-old rat pups and thalamus might be most vulnerable to hypoglycemia.Hypoglycemia might also elevate MMP-2 activity which is positively related to GSSG level and GSSG/GSH of the brain.

Objective To investigate the significance of acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) scoring system in evaluating elderly patients with hyperglycemic hyperosmolar state. Methods Elderly patients with hyperglycemic hyperosmolar state were enrolled in the study from January 2003 to May 2008. The patients were divided into two groups according to the outcome: death group and survival group. APACHE Ⅱ scoring system was used on the day of admission and the scores were compared in the two groups. The risk factors for death were evaluated by logistic regression analysis. Results Forty patients were registered including 10 cases in death group and 30 cases in survival group. The mortality rate was 25%. There were no differences in blood glucose, serum sodium, blood osmotic pressure, serum creatinine and hemoglobin between two groups before the treatment (t=-1.50~1.53, all P>0.05). The APACHE Ⅱ scores were significantly higher in death group than in survival group on the day of admission(30.1±5.4 vs. 22.9±3.9,Z=-4.08, P<0.01). Multiple logistic regression analysis showed that APACHE Ⅱ scores on the day of admission were the independent risk factor for death. Age, sex, blood glucose, effective blood osmotic pressure, serum creatinine and hemoglobin were not related to mortality rate. Conclusions APACHE Ⅱ scoring system is a helpful method for evaluating the severity and outcome of patients with hyperglycemic hyperosmolar state.
