AIM: To investigate the behavior of depression in chronic alcoholism and withdrawal model of mice, and to explore the co-mechanism of alcoholism and depression.METHODS: A novel model of chronic alcoholism was constructed in this study.The animals were divided into normal control group, and alcohol 7 d, 14 d, 21 d and 28 d groups.The mice were given alcohol preference test on the 6th, 13th, 20th and 27th days.After the test, alcohol were withdrawn for 1 d, then the next day the mice were given behavior test of depression.After the test, the mice were sacri-ficed.The contents of 5-hydroxytryptamine (5-HT) and norepinephrine (NE) were detected by HPLC.The expression of cAMP response element-binding protein ( CREB) and brain-derived neurotrophic factor ( BDNF) was detected by Western blot.RESULTS:The mice showed an obvious drinking phenomenon, and the immobility time of forced swimming test and tail suspension test was significantly increased, with increasing drinking days and withdrawal times.5-HT level in 7 d group mice only increased in frontal cortex (P<0.05).However, compared with control group, 5-HT levels in hippocampus and cortex were decreased on the 21th and 28th days (P<0.01).NE levels in 21 d and 28 d groups were decreased in hippo-campus and frontal cortex (P<0.05), and no significant change was observed in 7 d and 14 d groups.The protein levels of p-CREB and BDNF were significantly decreased in hippocampus and frontal cortex of 12 d and 28 d groups (P<0.05), and no significant change was observed in 7 d group and 14 d group.CONCLUSION:The co-mechanism of alcoholism, withdrawal and depression is related to 5-HT.5-HT-cAMP-CREB-BDNF signaling pathway may be a common mechanism for alcoholism and depression.

OBJECTIVE: To investigate the classification and distribution of external nasal fracture, and its influence to the nasal septum. METHOD: We randomly chose 60 patients who received nasal CT scan because of nasal trauma and diagnosed as external nasal fracture. We reviewed their CT data in PACS system with computer. RESULT: Of the 60 cases of nasal trauma, 90 sides got external nasal fracture, among which 58 sides (64.4%) had only nasal bone fracture, 16 sides (17.8%) had only maxillary frontal process fracture, and 16 sides (17.8%) had both. Half of these 60 patients got unilateral external nasal fracture, among whom 14 patients (46.7%) had traumatic nasal septum deviation meanwhile. The other 30 patients suffered from bilateral external nasal fracture, among whom 26 patients (86.7%) had traumatic nasal septum deviation. The difference between these two groups was statistically significant (P < 0.01). Moreover, 24 patients got fracture of either nasal bone or maxillary frontal process, 11 of whom (45.8%) got traumatic nasal septum deviation at the same time. The other 36 patients suffered fracture of both these two bones, 29 of whom (80.6%) had traumatic nasal septum deviation. The difference between these two groups was statistically significant (P < 0.01). We classified the nasal bone fracture as below: 16 patients with only unilateral external nasal fracture belonged to Type I, of whom 15 patients (25.0%) were type Ia with nasal bone or maxillary frontal process fracture and 1 patient (1.7%) fell into type Ib with fracture occurred on both of these two bones at the same side. Four patients suffered bilateral external nasal fracture belonged to type II, among whom 2 patients (3.3%) belonged to type IIa with nasal bone or maxillary frontal process fracture and 2 patients fell into type IIb with fracture of both of these two bones at different sides. The other 40 patients (66.7%) belonged to Tpye III, who suffered external nasal fracture accompanied with traumatic nasal septum deviation. CONCLUSION Traumatic nasal septum deviation was extremely concomitant in patients with external nasal fracture. It will be better to perform external nasal reconstructive surgery and plasty of nasal septum deviation by using the endoscope within 1 month for the patients whose symptom were serious or who cared a lot about the appearance.

Objective To investigate the levels of serum C-reactive protein in subjects with impaired fasting glycemia and its significance.Methods From Mar.to Sep.2005,according to oral 75 g glucose tolerance test(OGTT)in the patients in the First Hospital Affiliated to China Medical University,there are 30 subjects with normal glucose tolerance(NGT),28 cases with impaired fasting glycemia(IFG).CRP was detected with ELISA.Results (1)Serum CRP in the subjects with impaired fasting glycemia was significantly higher than those in normal subjects( P

Objective To explore the autobiographical memory characteristics of chronic pain patients and its correlators.Methods Autobiographical memory,pain and emotion of 106 chronic pain patients and 106healthy controls were assessed with the Autobiographical Memory Test (AMT), the Short-form McGill Pain Questionnaire (SF-MPQ), the Pain Self-efficacy Questionaire (PSEQ), Beck Depression Inventory (BDI) and Beck Anxiety Inventory (BAI).Results Compared to the control group, the clinical group had less specific memory (3.63 ± 1.53, 2.63 ± 1.68, F (1.416) = 7.233, P ＜ 0.01 ) and more overgeneral memory (2.37 ± 1.53,3.37 ±1.68, F (1.416) =7.069, P＜0.01 ),but the latency to response was not statistically significantly different between the groups.Duration of pain,frequence of pain and pain self-efficacy were the significant predictors of overgeneral memory,and the regression coefficients were significant (P＜0.05 ) ,the multiple regression equation was statistically significant( R = 0.427, R2 = 0.183, F= 2.385, P＜ 0.05 ).Conclusion The autobiographical memory of chronic pain patients was overgeneralized because of the influence of duration, frequence and self-efficacy of pain.

Objective This study aimed to discuss the different assessment of pain among medical and nursing staff and cancer patients and supply reference for proper analgesic precept for clinical application and nursing measures. Methods We collected the assessment of psychological pain and physiological pain by 55 hospitalization cancer patients, 40 physicians in-charge and 55 nurses in-charge in one week by Johnson inventory. The assessment results were compared and at the same time the relevant problems of the attitude to cancer pain by patients was also investigated. Results Improper recognition existed in cancer pain treatment by most cancer patients. The physiological pain was higher than the psychological pain assessed by both patients and nurses (P<0.05). But the pain assessment by patients was higher than that by the nurses (P<0.05). The assessment of psychological pain was higher than the physiological pain by doctors and both aspects were lower than those by patients, but no statistical difference was seen (P>0.05). The assessment by doctors was more accurate than that by nurses. Conclusions Routine establishment of pain assessment inventory for patients could instruct patients how to record the degree of their pain. We should strengthen the standard training about pain management knowledge and give timely communication with patients' cancer pain.

Objective To observe the effect and mechanism of nasal continuous positive airway pressure(nCPAP)in the treatment of obstructive sleep apnea/hypopnea syndrome(OSAHS)with coronary heart disease.Methods 126 OSAHS patients with coronary heart disease were randomly divided into two groups.The treatment group was treated by nCPAP on the basis of former medicine but the control group was treated by former methods.Three months later,polysomnography(PSG)and the holter ECG examination were conducted.Results After three months,the nocturnal myocardial ischemia episodes decreased significantly in both groups(55.6%and 6.35%,P＜0.01).Conclusion nCPAP may abolish sleep apnea and hypopnea,correct hypoxemia,reduce the nocturnal mean heart rate and systolic blood pressure,and improve myocardial ischemia episodes,so to reduce the incidence of cardiac end-point events.

ObjectiveTo investigate the efficacy of bundle treatment on patients with moderate or severe acute respiratory distress syndrome (ARDS).Methods A multicenter prospective observational study comparing the result of historical treatment strategy and bundle treatment was conducted. According to the new Berlin standard of definition, 73 patients with moderate or severe ARDS due to pulmonary factors, age from 18 to 65 years, admitted to Department of Critical Care Medicine of Taian Central Hospital and Handan Central Hospital were enrolled. Thirty-three patients admitted during September 2012 to May 2014 (prospective observation period) were enrolled as the bundle treatment group. Forty patients with matched disease history admitted from January 2010 to August 2012 were enrolled as the control group. The patients in bundle treatment group received bundle treatment based on the treatment strategy of primary diseases. Bundle treatment included restrictive fluid management, respiratory support, high-dose ambroxol combined with Xuebijing injection, prevention of ventilation associated pneumonia (VAP), individualized sedation plan, installation of continuous blood purification treatment for critical patients. A special team was organized to ensure the successful implementation of all bundle measures. The acute physiology and chronic health evaluationⅡ (APACHEⅡ) score, oxygenation index, duration of mechanical ventilation, the length of intensive care unit (ICU) stay, incidence of VAP, and 28-day mortality 5 days after treatment were compared between two groups.Results There were no significant differences in basic characteristics of patients between the two groups, including gender, age, etiology, severity, etc. (allP> 0.05) with comparability. Compared with the control group, there was no significant difference in APACHEⅡ score 5 days after treatment in bundle treatment group (15.1±2.8 vs. 16.2±3.0,t = 1.618,P = 0.110). Compared with control group, oxygenation index in bundle treatment group was significantly improved [mmHg (1 mmHg = 0.133 kPa): 135.4±34.5 vs. 117.1±34.2,t = -2.273,P = 0.026), the duration of mechanical ventilation was obviously reduced (days: 8.70±2.50 vs. 10.10±2.67,t = 2.308,P = 0.024), incidence of VAP was significantly lower [18.2% (6/33) vs. 32.5% (13/40),χ2 = 5.027,P = 0.025], and 28-day mortality rate was obviously lowered [24.2% (8/33) vs. 37.5% (15/40),χ2 = 4.372,P = 0.037], the length of ICU stay shown no statistical difference (days:10.40±1.94 vs. 11.30±2.34,t = 1.620,P = 0.110).Conclusion Implementation of bundle treatment can significantly shorten the duration of mechanical ventilation, reduce the incidence of VAP, and improve the prognosis of patients.

Adhesion molecules(AMs) is one kind of glycoproteins expressed on cell surface that can induce interactions between cells or cell and ECM. AMs are indicated to be involved in many chronic complications of diabetes mellitus. Thus, drugs that can decrease levels of AMs are potential new prevention and therapy of diabetic angiopathy.-

Objective To study the effects of community-based rehabilitation on cerebral apoplexy patients with cognitive disorders.Methods 30 cases of cerebral apoplexy patients were enrolled according to relevant standards,who were given standard rehabihtation care in Community Health Service Center(training group) ,while another 30 similar cases from subordinate health service stations (control group) given only rehabilitation guidance once a week.Two groups were not do professional cognitive training.All patients were assessed with Mini Mental State Examination( MMSE), Fugl-Meyer Assessment(FMA) and modified Bathel index rating scale(MBI) to evaluate their cognition ,movement function and activity of daily living(ADL) before training as well as after 4-week and 8-week training.Results There was no signficant difference in cognition,movement functions and ADL between training group and control group before treatment(P>0.05).The differences in the assessment of Brounnstrom scale and MBI between two groups after 4-week training were not significant( P > 0.05 ).The scores of Fugl-Meyer scale, MMSE and Barthel index of the training group after 8-week training were significantly higher than those of control group( all P < 0.05 ).Conclusion Community-based rehabilitation training could improve the movement functions and ADL,and cognitive functions of cerebral apoplexy patients.

Objective:To investigate the influence of Covid-19 epidemic on the number of acute ischemic stroke patients with intravenous thrombolytic therapy in Dalian in 2020, the way to hospital, onset to door time (ODT), door to needle time(DNT), onset to needle time(ONT), and the National Institute of Health Stroke Scale (NIHSS) before and after intravenous thrombolytic therapy.Methods:This was a retrospective descriptive study on 13 map-participating hospitals in Dalian from August 2020 to December 2020. The number of acute ischemic stroke patients with intravenous thrombolytic therapy, ODT, DNT, ONT, modes of transport to hospital, the NIHSS score before and after intravenous thrombolytic therapy, etc were analyzed. Data were collected from August 1, 2020 to December 31, 2020, and compared with the baseline data from the same period in 2019.Results:SPSS 22.0 statistical software and Data Analysis ToolPak were used for statistical analysis of the obtained data, and T tests statistic was used for data analysis. In 2020,the number of acute ischemic stroke patients with intravenous thrombolytic therapy increased (681 cases vs 416 cases), and DNT increased [50 minutes vs 45 minutes P = 0.01]. In 2020, 83.55% of patients indicated self-visit as their main mode of transport to the hospital. In 2020, among the self-visit patients with NIHSS score<15 scores,the number of the patients with the NHISS score unchanged or decreased after intravenous thrombolytic therapy was more (562 scores vs. 535 scores, P<0.001), and the patients with NIHSS score ≥15 scores were more willing to call ambulances to hospital. Conclusions:During the Covid-19 epidemic period of 2020, the number of acute ischemic stroke patients receiving intravenous thrombolytic therapy increased, DNT increase; the patients withNIHSS score<15 scores are more willing to choose to visit the hospital using their own transportation and benefit from intravenous thrombolytic therapy. The patients with NIHSS ≥15 scores prefer to call ambulances to hospital.
