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.

PC84045 human lung carcinoma cells (PC84045 HLCCs) were mixed with the BM cells activated by anti-CD3 McAb and IL-2 and then CD3-ALTO4 bi-specific McAbs was put into the cell suspension. The mixed cells were cultured for 3 days in presence of IL-2 and IL-3. Tumor cell colony formation method in half-solid culture system was used to assess the purging efficiency (PE) of the activated T cells to PC84045 HLCCs. The ratio of T cells to PC84045 HLCCs was 8 to 1, the PE was 4 Logs. The rario of T cells to PC84045 HLCCs was 16 tol, the PE was 5 Logs. When the purged BM cells were injected into the NC nude mice, none of subcutaneous node was found. The number of the CFU-GM, BFU-E of the purged BM cells was more than 85 % compared with that of the fresh BM cells (P

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 build the method of computerized case classification,for the purpose of perfecting the diseases typing and classification,and supporting the management based on the quality and expenses of the disease.Methods 875 cases were defined into two types.Eight parameters were selected for non-surgery cases,namely the disease diagnosis,severity at admission,and age.For surgery cases,five parameters were defined,namely the disease diagnosis,operative quantity,and severity at admission.Then Fisher function was called into play to obtain the function descriminant equation,realizing computerized classification.Results The rate of matching was 86.2％ between computerized classification and manual classification.The high accuracy of function descriminant equation proves the satisfactory outcomes of the classification.Collusion The computerized classification is satisfactory in its outcomes,and therefore it can better quality of care and cost management of diseases in clinical practice.

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.

Objective To analyze the clinical features, laboratory findings, electroencephalography (EEG) and neuroimaging of the neurosyphilis presented with parkinsonism as the principal manifestation to improve the diagnosis of neurosyphilis. Methods Eight eurosyphilis patients were from department of neurology of Hainan provincial people’s hospital from early July 2010 to December 2014. We retrospectively analyzed the clinical manifestation, laboratory exami?nations, neuroimaging examinations, diagnosis and treatment outcomes of 8 cases neurosyphilis who presented with par?kinsonism as principal manifestation. Results Myotonia and bradykinesia were principal symptoms in these 8 cases. Limb tremor, posture disorder, abnormal mental behavior and cognitive impairment occurred in some patients. Serum treponema pallidum particle agglutination (TPPA) and toluidine red untreated serum test (TRUST)were positive in 8 cas?es. Cerebrospinal fluid (CSF) protein and cell counts were elevated in all the patients. CSF-TPPA and TRUST were posi?tive in all the patients. The MRI showed that cerebral infarction in basal ganglia, cerebral atrophy in temporal lobe and hippocampus and ventricular enlargement in all the patients. EEG showed abnormal activity in all the patients. After treatment with a large dose of penicillin, clinical symptoms were obviously improved;the titer of serum and CSF TRUST decreased;and scores of UPDRS decreased in all the patients. Conclusions There is a wide variation in the clinical man?ifestation of the neurosyphilis. When patients present with Parkinsonism, we should comprehensively analyze the laborato?ry examinations, EEG and neuroimaging to rule out the possibility of neurosyphilis.

Object To study the microwave assisted procedure for the extraction of baicalin from root of Scutellariae baicalensis Georgi Methods An MSP 100D domestically made microwave sample preparation system with a maximum power of 850 watts was used. The effects of solvents, pressure/temperature of solvents and microwave radiation time on the yield of baicalin were studied by orthogonal experimental design. Results The optimal experimental conditions were extraction at 70% of microwave power with 30 times of 35% ethanol at a constant heating pressure/temperature of 0.15 MPa for 30 s. Conclusion The microwave assisted extraction not only takes a shorter time with better parallel results, but also gave an increased yield of about 10% as compared with ultrasonic extraction.

Objective To compare the effects and cost of peripheral intravenous catheter (PIV) and peripherally inserted central catheter (PICC) on very low birth weight infants (VLBWI).Methods From July 2013 to August 2015,95 VLBWI with PICC (PICC group) and 90 VLBWI with PIV (PIV group) admitted to the Neonatal Intensive Care Unit (NICU) of Changzhi Maternal and Child Care Hospital were included in the analysis.The two groups were compared in body mass increase,average length of hospital stay,incidence of catheter-related complications,and care cost and effect.Results The body mass increase per weak was higher in the PICC group than in the PIV group,with statistically significant difference (P ＜ 0.05).The average length of hospital stay in the PICC group was shorter than that in the PIV group [(48.2 ± 5.2) d vs.(53.2 ± 8.1) d,P ＜ 0.05].The incidence of catheter-related complications was lower in the PICC group than in the PIV group (35.4％ vs.44.9％),including phlebitis (PICC group,21 person-times;PIV group,169 person-times),liquid leakage or exosmose (PICC group,2 person-times;PIV group,185 person-times),and catheter prolapse (PICC group,3 person-times;PIV group,145 person-times) with statistically significant differences (all P ＜ 0.05),and catheter blockage (PICC group,7 person-times;PIV group,84 person-times) and other complications such as venous embolism and infection (PICC group,1 person-time;PIV group,3 person-times) with no statistically significant differences (all P ＞ 0.05).The average monthly cost in the PICC group (1 951.5 yuan) was lower than that in the PIV group (2 008.5 yuan),and the cost of single insertion in the PICC group (1 691.5 yuan) was higher than that in the PIV group (129.9 yuan),the cost-effectiveness was better in the PICC group than in the PIV group (30.22 vs.36.45).Conclusions For VLBWI,PICC can reduce the times of venous puncture,the incidence of complications,and promote body mass increase.However,the monthly cost was similar between the two groups in this study,possibly because of the short-time of this study.The advantages in cost-effectiveness of PICC may become more prominent when the catheter dwelling time extends.

Objective To assess the effectiveness of repeated trans-cranial magnetic stimulation ( rTMS) in relieving post-stroke depression ( PSD). Methods PubMed, Embase, the Cochrane library, Web of Science, CNKI, WANFANG, and VIP were searched for reports of randomized, controlled trials of rTMS treatment of PSD published before June 2015. Crude standardized mean differences ( SMDs) and odds ratios with 95% confidence in-tervals ( CIs) were calculated for depression intensity and effectiveness rate after treatment using random or fixed effects models. Results Twenty-four studies involving 856 rTMS-treated patients and 802 control patients were in-cluded in the meta-analysis. The results showed that compared with the control group, PSD patients showed significant reductions in depression after rTMS treatment ( SMD=-1.36;95% CI-1.6 to-1.12;P≤0.05) . The total effective-ness rate in the treated group was 85% with a reduction in NIHSS score ( SMD=-0.82;95% CI-1.2 to-0.44;P≤0.05) . Subgroup analysis showed that neither the frequency of rTMS stimulation, the site stimulated, nor time after stroke had a significant influence on the effectiveness of rTMS. Additionally, a few studies reported adverse reactions after rTMS. Conclusion rTMS appears to be a safe and effective therapy for PSD. Further well-controlled trials may elucidate the mechanism underlying the placebo effects of the sham rTMS observed among PSD patients.
