[Objective]The intervention of electroacupuncture (EA) on chronic inflammation and cyclooxygenase-1/-2 mRNA expressions in rats with II collagen-induced arthritis was observed in vivo, so as to discuss the effect of EA on chronic inflammation and its pivotal mechanism. [Method]Wistar rats immunized intradermally with bovine type II collagen, were served as the animal models of chronic inflammation. EA stimulation, begun on day 11 after the injection, was applied at the acupoint equivalent to ST36 for continuous 10 times. Indomethacin and refecoxib were used respectively as the control treatments of NSAID inhibitor and COX-2 selective inhibitor. The arthritic index, swelling volume of paw and concentrations of prostaglandin E_2 (PGE_2) of local tissue were investigated. Furthermore, we investigated the impact of EA on the levels of COX-1 mRNA and COX-2 mRNA in synovial tissues and gastric mucosa of inflammatory rats by using reverse transcriptase-polymerase chain reaction (RT-PCR). [Results]All collagen-injected rats developed chronic inflammation of paws. EA remarkably reduced the paw swellings of rats on day 16 and day 21 and attenuated the severity of arthritis from the day 14 to day 21. The levels of PGE_2 in the inflammatory tissues of swollen paws were also lowered by EA. EA stimulation obviously down-regulated the expression of COX-2 mRNA in synovial tissue, but did not influence the level of COX-1 mRNA expressed in gastric mucosa. Indomethacin and refecoxib also strongly down-regulated COX-2 expression in synovial tissue. However, either indomethacin or refecoxib strongly affected the COX-1 mRNA expressions in gastric mucosa. [Conclusion] EA has a pronounced anti-inflammatory effect on collagen-induced arthritis, and the pivotal mechanism and also the advantage of its therapeutic result may be due to selective suppression of COX-2 gene activation, without destroying COX-1 activity in stomach.

Objective To investigate the CT and MRI features of intraductal papillary neoplasm of the bile duct (IPNB).Methods Thirty eight patients with IPNB finally diagnosed by puncture biopsy or surgery were enrolled in this study.All the CT or MRI data were investigated retrospectively.Twenty one patients underwent CT examinations,17 patients underwent MRI examinations.The features of IPNB including the distribution features of the nodules or masses,CT and MRI features of cholangiectasis,mucus were analyzed.The accuracy differences of CT and MRI for the preoperatively diagnosing mucus and tumor growing along mucous were compared by nonparametric test.Results The lesions (including 5 patients with solitary lesions and 19 patients with multiple lesions) were located in intrahepatic bile duct in 24 patients,3 patients occurred simultaneously in intrahepatic and portal bile duct,2 lesions occurred in portal bile duct,8 lesions occurred in common bile duct,the lesions of 1 patient occurred simultaneously in common bile duct,cystic duct and gallbladder.Seventeen and 11 patients appeared nodules locating in dilated bile duct on CT and MRI,respectively.Four and 5 patients appeared cystic lesions with multiple nodules of the liver on CT and MRI,respectively.Higher contrast enhancement on CT and MRI in arterial phase than that in portal vein and equilibrium phase were observed in 18 and 12 patients,respectively.Excluding the patients undergoing puncture,CT was better than MRI in evaluating whether the mucus was present,with the accuracies of 30.0％ (6/20) and 6.3％ (1/16) for CT and M RI,respectively (Z =2.58,P ＜ 0.05).CT was worse than MRI in preoperatively evaluating the features of tumor growing along mucous,with the accuracies of 77.8％ (14/18) and 92.6％ (13/14) for CT and MRI,respectively (Z =4.23,P ＜ 0.01).Conclusion IPNB had the features of growing along mucous of the bile duct,nodule or mass in dilated bile duct and other features,CT and MRI are important in diagnosing the IPNB.

BACKGROUND: Bronchial asthma is one of those diseases that are significantly affected by meteorological factors. There is close relationship between asthma attack and meteorological factor. There have been some studies on the relationship between asthma and meteorological factors at home and abroad, but the results are various due to different area conditions.OBJECTIVE: To analyze the relationship between asthmatic attack and meteorological factors in children in Qingdao city.DESIGN: Observational experiment.SETTING: The Affiliated Hospital of Qingdao University Medical College.PARTICIPANTS: Altogether 445 inpatient children, 307 males, 138 females, aged ＜ 14 years, who were diagnosed of asthma attack definitely, of the Affiliated Hospital of Qingdao University Medical University, Qingdao Haici Hospital,Qingdao Children Hospital between January 1st 2000 and December 31st 2004 were retrieved.METHODS: The asthmatic attack time of 445 children patients with asthmatic attack of Qingdao city and concurrent month mean temperature, air pressure, relative humidity, wind speed and other meteorologic al data were collected.Seasonal rhythm of asthmatic attack in children and the relationship between asthmatic attack and meteorological factors were analyzed with circular distribution analysis and linear regression analysis, respectively.MAIN OUTCOME MEASURES: ①Month attack information of 445 asthma patients. ② Circular distribution analysis results of asthmatic attack time. ③ Linear regression analysis results about the relationship between asthma attack and meteorological factors.RESULTS: ① Data revealed that asthmatic attack in Qingdao city focused on November, December, January and February, which took up 47.9% of total amount in that year. There were 307 male patients (incidence 3.12%)in a year,female patients only 138 cases (incidence 1.51%), which revealed that boys have a higher incidence of asthma attack than girls. ②The peak season of incidence of asthmatic attack was found in winter and peak season for male and female patients was in January and December, respectively (P ＜ 0.05). ③ Higher incidence of asthmatic attack of children was related with higher air pressure, lower temperature, lower relative humidity(r =0.435, -0.320, -0.296, all P ＜ 0.05).CONCLUSION: The incidence of asthma attack presents seasonal rhythm in Qingdao city and it is influenced by climate conditions. Therefore, enough consideration of meteorological factors should be paid on preventive works for asthma.

Objective:To evaluate the effects of humanistic care on medication compliance and social function of schizophrenic patients. Methods:76 patients with schizophrenia were randomly divided into two groups within two days of hospital admission. The observational group was applied humanistic care but the control group with rou-tine care. All the information related to the present study was collected using unified language. At the time of ad-mission, day 1, day 14, day 28 and day 56 after the intervention, the effect of humanistic care was evaluated by medication compliance, Brief Psychiatric Rating Scale ( BPRS) , Personal and Social Performance Scale ( PSP) and Family Concern Index Questionnaire ( APGAR) . Results:The patient′s medication compliance rate in the obser-vational group was higher than those in the control group, especially, at the time of day 56, the patients in the ob-servational group ( full compliance : 66%, partial compliance: 44%) was significantly better than those in the control group ( full compliance 19%, partial compliance 66%, incompliance 15%) . There were no statistical difference in the two groups of the BPRS scores on day 1 and day 14 of admission, however, the scores of the pa-tients in the observational group was significantly lower than those in the control group on day 28 and day 56 . As for PSP, the result was similar to BPRS on day 1 and day 14, while the PSP score of the patients in the observational group was significantly higher than those in the control group on day 28 and day 56. In terms of APGAR, the score of the patients in the observational group was significantly higher than those in the control study except day 1 of ad-mission. Conclusion:Humanistic care has positive effects on medication compliance and social function of schizo-phrenic patients especially after hospital discharge. The implementation of humanistic care would guide patients to maintain the capacity of life, labor and social communication, enhance the patient's sense of control over life, and improve their confidence to overcome the disease. With humanistic care, patients are more willing to cooperate with treatment, and further to reduce the recurrence and degradation of social function.

[Abstract ] Objective The mechanism of psychological stressi-nduced damage to vascular endothelial cells (VEC) is not yet clear.This study was to investigate the impact of psychological stress on the NO level and NO-related regulatory protein expression in the plasma of rat models of psychological stress-induced VEC injury. Methods Twenty male SD rats were equally randomized into a con-trol group and a model group, the former raised together, with water regularly fed at 9:00 and 21:00 hours for 10 minutes a day, while the latter raised alone, with water regularly fed at the same hours for 10 minutes a day for the first 7 days and then with water or an empty bottle at the same hours for 10 minutes a day according to the random table.Ninety days later,all the rats were intraperitoneally injected with normal saline at 0.2 ml per 100 g body weight twice a day.Then the behaviors of the animals were observed by open field tests, the contents of cortisol (COR),adrenaline (Adr), and endothelin-1 (ET-1) in the plasma measured by ELISA, the NO level detected by the nitrate reductase method, and the expression of NO-related regulatory proteins in VECs determined by LC-ESI-MS. Results Com-pared with the control group, the model rats showed significant increases in the vertical score (7.00 ±0.70 vs 11.28 ±1.79), horizontal score (37.60 ±4.500 vs 56.25 ±1.71), and total score (44.50 ±5.50 vs 67.25 ±2.98) (P<0.01) as well as in the levels of COR ([65.28 ±2.21] vs [83.85 ±1.95] ng/mL ) and Adr ([3.85 ±0.35] vs [15.14 ±3.97] pg/mL) (P<0.01), but a remarkable de-with vacuoles in the VECs in the model group and structural integrity, ridge clarity, and tight pack in the VEC mitochondria in the con-trol. Conclusion Psychological stress induced by empty bottle stimulation can reduce the NO level and the expression of NO-related regulatory proteins in the plasma, which may cause both functional and structural damages to VECs.
