Objective: To explore Five-Factor Model personality traits of OCD patients who also diagnosed with personality disorders. Methods:SCID-I/P was administrated to diagnose OCD patients. PDQ+4 and PDI-IV were then administrated to 44 OCD subjects to determine whether they also suffered from personality disorders. FFM (five factor model of personality) of the subjects were measured with NEO-PI-R.Results: 32 of 44 (72%) OCD patients also met DSM-IV-TR criteria for personality disorder. Subjects with PDs demonstrated high Neuroticism (67.9?7.7), low Extraversion (39.0?10.2), low Agreeableness (42.6?7.7), low Conscientiousness (39.3?12.4), and normal Openness to Experience (45.9?8.8). Subjects without PDs, however, scored normally except for low Openness to Experiences (38.3?13.4).Conclusion: Deviant FFM characters of OCD patients with PDs suggesting that they often experience neglect emotion, introversion, and interpersonal confliction. Low openness to experiences of subjects without PDs indicates that they lack of curiosity, have relatively narrow interest and conservative ideas.

Objective: To explore childhood traumatic experiences of OCD patients who were also diagnosed personality disorders (PDs) and those without PDs. Methods:SCID-I/P was administrated to diagnose OCD patients. PDQ+4 and PDI-IV were then administrated to 44 OCD subjects to determine whether they also suffered from personality disorders. Childhood maltreatment experiences of the sample were measured with Childhood Trauma Questionnaire (CTQ).50 normal control were also collected and subjected to CTQ-SF tests. Results:32 of 44 (72%) OCD patients also met DSM-IV criteria for personality disorders. OCD patients scored significantly higher than normal control in CTQ-SF (Childhood Truma Questionuaire-28 Short Form) and in all domains with the exception of physical abuse. Comparison between OCD subjects with PDs and normal control, the former scored significantly higher in emotional abuse (55.10/32.54), sex abuse (49.63/36.30), physical neglect (52.03/34.76), and emotional neglect domains (55.84/32.32). Whereas OCD subjects without PDs only scored significantly higher in emotional neglect domains compared with normal control (42.50/28.26).Conclusions:Subjects with PDs experienced more severe traumatic events during their early life. "pure OCD" patients, however, might experienced more emotional neglect.

BACKGROUND: It is believed previously that hyperbaric oxygen(HBO)therapy can prevent stroke, but some scholars think HBO therapy on the contrary can induce stroke although its pathogen and prevention are unclear.OBJECTIVE: To study the reason of cerebral thrombosis induced by HBO and the preventive effects of the medicine.DESIGN: A retrospective study based on patients as subjects.SETTING: Department of HBO in a military area command hospital ofChinese PLA.PARTICIPANTS: Totally 192 hospitalized patients receiving HBO therapy in Guangzhou General Hospital of Guangzhou Military Area Command of Chinese PLA were selected, in which there were 127 males and 65 females aged between 9 and 78 years old. A total of 6 cases including 3 male and 3 female cases aged between 51 and 76 years old developed cerebral thrombosis during therapy.METHODS: The background factors of 192 patients who received HBO therapy and the included 6 cerebral thrombosis cases were analyzed. Totally preventive effects of the medicine on a cluster level of different risk factor. Three groups of patients received different interventions under the prerequisites of routine medications including blood-activating and stasis-eliminating, neurotrophy, and vasodilator patients of nitric ether group received oral administration of isosorbide dinitrate or glycerin trinitrate; patients of calcium antagonist group received oral administration of Sibelium or Novarsc; and patients of no specific medication group did not receive any preventive medicine.MAIN OUTCOME MEASURES: Patients' symptoms, physical signs andhead CT or MRI.RESULTS: The risk factor of cerebral thrombosis induced by HBO was the basic disease of hyperlipidemia or hypertension, etc. A total of 115 cases had the cluster with less than 4 risk factors and none of them developed thrombosis. A total of 31 cases had the cluster with 4 or more than 4 risk factors and 6 of them developed thrombosis with greatly increased morbidity. Above the level of 4 risk factors, nitrate ether had effective preventive effect(0/13) while there was 33.3% of the patients(5/15) in calcium antagonist group developed thrombosis, and the difference between the above two groups was significant( P ＜ 0.05).CONCLUSION: The cluster level of risk factors has close relationship with the probability of thrombosis induced by HBO. Nitrate ether has significant preventive effects.

AIM To evaluate the antagonizing activity of iQWcF, a modified tripeptide, to endothelin receptors. METHORDS ①Vasoconstriction experiments with aorta strips of rats. ② In vivo experiments:male normotensive Wistar rats were anesthetized with pentobarbital Na (50 mg?kg -1 ),and catheterized into the carotic artery for measurement of blood pressure, and into the femoral vein for administration of iQWcF (30 mg?kg -1 ) and ET 1(0 9 nmol?kg -1 ). The test compound was given intravenously 5 min before the bolus injection of ET 1. Control animals received saline on the same time schedule.The blood pressure was recorded at different time interval after injecting ET 1. RESULTS ①iQWcF prohibited the vascontriction of aorta induced by ET 1 in a concentration dependent fashion.②The compound(30 mg?kg -1 .iv) markedly antagonized ET 1 induced the long lasting pressor phase mediated by ET A without affecting early transient depressor phase by ET B. CONCLUSION iQWcF is one of ET A selective antagonists.

Objective To ascertain the role of NF?B and relationship among TGF?1,caspase-3 and apoptosis in CsA-induced nephrotoxicity.Methods Sixty-four wistar male rats were randomly divided into 4 groups:Vehicle,PDTC,CsA and CsA + PDTC group.The animals were daily subcutaneously injected either with CsA(15 mg/kg)or vehicle/PDTC(100 mg/kg).Four weeks later,BUN,serum creatinine,NAG and urine routine were examined.The kidneys were processed for light microscopy,immunohistochemistry and TENUL.Results A rat model of CsA-induced nephrotoxicity was established.CsA group showed significant increase in BUN,SCr and urine NAG compared with the controls,whereas CsA + PDTC group did not.Apoptosis is observered by TUNEL and the expressions of NF-?B,TGF-?1,caspase-3 increased significantly in CsA group compared with conrtol group.Whereas,both the apoptosis and the expressions of these proteins significantly decreased in rats treated with PDTC.Conclusion Apoptosis is induced in the CsA-induced chronic nephrotoxicity.Inhibition of NF-?B activation blockaded apoptosis and ameliorated CsA-induced chronic nephrotoxicity.The results suggest that NF-?B plays important roles in the progression of chronic CsA nephrotoxicity.

ObjectiveTo study the operative procedure and effect of anastomostic pseudoaneurysm(APA). Methods Eleven patients with APA were treated surgically. The diagnosis of APA in all the patients was comfirmed by angiography and ultras onic examination. A small rupture leading to APA was repaired by lateral arteri orrhaphy using autologous vein patch in 4 cases; the APA caused by a big rupture of anastomosis,resection of the pseudoaneurysm and interposition o f a PTFE or antologous vein were used in 7 cases.Results10cas es were followed -up for 5-38 months (mean19.6 months),and 1case loss of follow-up.9 cases recovered to be normal in activities and works, only 1 ca se had nerve paralysis of the affect extremity caused by popliteal artery APA compression . All the cases have good blood perfusion of the extremities wit hout recurrence. Conclusions APA should be treated by surgery. During operation control blood vessels effectively and remove the pathological changetissues completely are important,and reasonable application of antibi otics and antithrombotic agents are the guarantee of getting successful results .

Objective To explore the feaibility of laparoscopic hepatectomy(LH) for hepatolithiasis.Methods Eight patients with hepatolithiasis were treated by laparoscopic cholecystectomy(LC) and common bile duct exploration(LCBDE) and LH.Laparoscopic resection of left lateral lobe of liver was performed in 7 cases,and left hemihepatectomy in 1 case.Results Procedures were all successful with operation time of(285.00?37.42) minutes,and bleeding volume(306.25?29.73)mL.The postoperative hospital stay was(7.88?1.36) days.No complications occurred.No residual stone was found in any patient.Conclusions LH was safe and effective for hepatolithiasis,and gives better results when combined with choledoscopic stone removal.

Objective:To study the reversal effect of tamoxifen(TAM)on the expression of mdr1 in human pancreatic cancer cell lines.Methods:The inhibtion effect of TAM on pancreatic cancer cell line SW1999、Capan-Ⅱ and mammary cancer cell line T47D were studied;The influence of TAM on mdr1 protein/mRNA expression in SW1999、Capan-Ⅱ and T47D were studied using the method of flow cytometer and RT-PCR.Results:The high dose TAM could inhibit Capan-Ⅱ cell line.TAM could reverse the expression of mdr1 protein and mRNA in Capan-Ⅱ cell line and T47D cell line. Conclusion:The high dose TAM could inhibit Capan-Ⅱ cell line,maybe related with reduction of the expression of mdr1 protein and mRNA.
