Objective:To analyze the complications of interventional chemotherapy for breast cancer by two different ways to rationally select interventional chemotherapy ways with low risks of complications.Methods:A total of 91 cases of breast cancer were divided into 2 groups,interventional chemotherapy group through ulnar artery(i.e.,ulnar artery group)with 28 cases and interventional chemotherapy group through femoral artery(i.e.,femoral artery group)with 63 cases.Both groups were operated with local anesthesia in DSA room,and the chemotherapeutic drugs were perfused when the catheters were inserted into the proximal side of the cross of infraclavicular artery and internal thoracic artery.The catheters in ulnar artery group were kept for 1 to 2 therapeutic courses,but not in femoral artery group.The complications were observed and analyzed.Results:The occurrence rate of complication in ulnar artery group was 39.29%(11cases),which was significantly higher than that(6.35%,4 cases)of femoral artery group(?2=12.98,P

Objective The changes of Glutamic acid(Glu) and GABA immunoreaction in the cerebral cortex and hippocampus of rats with seizure induced by IL-1? and IL-6 were studied.To explore the mechanism of IL-1? and IL-6 in epilepsy. Methods Experimental rats were randomly divided into 3 groups:control group,IL-1? group,and IL-6 group.After intracerebroventricular injection of relevant reagents for 120?min,behaviour changes were observed,Glu and GABA were examined by means of immunohistochemistry in the cerebral cortex and hippocampus of rats. Results The behaviour observation indicated that no seizure happened in control group,seizure in middle degree was observed in IL-1? group and IL-6 group.Compared with in control group,the immunoreaction of Glu showed that the expression was significantly increased in IL-1? group and IL-6 bgroup,while GABA was obviously decreased after intracerebroventricular injection IL-1? or IL-6 at 120?min.Conclusion The machanism of that IL-1? or IL-6 particpated in promotion and abduction epilepsy may be through increasing Glu and decreasing GABA in the cerebral cortex and hippocampus.The nerve excitation is enhanced and then epilepsy occurred.

Heart failure(HF)is the end stage of many cardiovascular diseases. Both the neurohumor overactivation and ventricular remodeling are the critical pathophy-siological processes of HF. It has been demonstrated that the serum level of brain natriuretic peptide (BNP) is elevated obviously in HF patients. As a circulatory hormone,BNP is mainly produced in cardiac ventricle. Through the natriuretic receptor(NPR)-cyclic guanosine monophosphate(cGMP)pathway, BNP performs the properties of natriuresis,diuresis, vasodilatation,enhancing vagal reflex and inhibiting sympathetic activity, which can improve the hemodynamic of HF without activation of plasma renin. It has been reported that BNP has effects of antihypertrophic and antifibrotic and plays a role in the antiventricular remodeling. In a word, BNP plays an important role of cardioprotection in the development and prognosis of HF though the local autocrine and/orparacrine ways.

Objective To explore the status of college students’ attachment and locus of control, and explore their relationship. Methods A total of 198 college students were surveyed adopting Experiences in Close Relationships Inventory and Internality, Powerful Others and Chance Questionnaire. Results The distribution of college student′s attachment type was not balanced,the proportion of dismissing type,security type, fearful type, preoccupied type accounting for 43. 9%,31. 3%,21. 7%,3. 1% respectively. The scores of internality, chance and powerful others were (27. 59 ± 5. 44),(17. 92 ± 6. 66),(17. 70 ± 7. 32) respectively. Attachment avoidance correlated negatively with internality(r= -0. 259,P<0. 01), and positively with chance and powerful others(r=0. 206,0. 221,P<0. 01);besides there was a positive correlation between attachment anxiety and chance,powerful others(r=0. 378, 0. 410,P<0. 01). Attachment avoidance had prediction on internality(R2 =0. 067,P<0. 01). Attachment anxiety had prediction on chance and powerful others(R2 =0. 143,0. 168,P<0. 01). Conclusion College students’ at-tachment has significant effects on locus of control.

BACKGROUND: Tetramethylpyrazine has the protective effect against the central nervous system injury. The structural changes in Nissl bodies were regarded as a marker of neuron injury.OBJECTIVE: To investigate the effect of tetramethylpyrazine on the structure and the quantity of Nissl bodies of cerebral neurons in rat with epilepsy.DESIGN: A comparative study.SETTING: It was conducted at the Physiological Department of Medical School of Xianning College.MATERIALS: From September 2004 to March 2005, it was completed at the Anatomy Department of Tongji Medical College, Huazhong University of Science and Technology. Forty healthy SD rats aging 3-4 months, weighing (250±50) g and regardless of their gender, were selected.METHODS: Rats underwent anesthesia and craniotomy. Then their cerebral cortex were exposed for placing BL-410 Experimental System of Biological Function (TME, China) to record the bilateral EEG of the brain and the seizure in rats with penicillin-induced epilepsy group and the 10 mg/kg tetramethylpyrazine group, 20 mg/kg tetramethylpyrazine group and 40 mg/kg tetramethylpyrazine group. In control groups, the brains of rats were taken out at 1 hour after craniotomy. In penicillin-induced epilepsy group, their brains were taken out at 1 hour after penicillin-induced epilepsy. In 10 mg/kg tetramethylpyrazine group, 20 mg/kg tetramethylpyrazine group and 40 mg/kg tetramethylpyrazine group, after stable penicillin-induced epilepsy, tetramethylpyrazine was injected intraperitoneally at a dose of 10 mg/kg, 20 mg/kg and 40 mg/kg, respectively.When the greatest protective effect of tetramethylpyrazine appeared, the rats' brains were taken out. Brain sections were sliced. Nissl bodies were stained by thionine staining. Under light microscope, structures of Nissl bodies were observed and the images of Nissl bodies were quantitatively analyzed by HPIAS-1000 high acuity color pathologic diagram-writing analyzing system. In each group, the average absorbency of 15 fields was regarded as the average absorbency of Nissl bodies in that group.MAIN OUTCOME MEASURES: In all the groups, the structure and the quantity of Nissl bodies of cortical neurons in rats were studied.of the structure of Nissl bodies in external granular layer cells and external pyramidal layer cells. In control group, multi-layer blue-stained and clumplike or granule-like Nissl bodies could be observed. In penicillin-induced epilepsy group, Nissl bodies were completely resolved and disappeared. In 10 mg/kg tetramethylpyrazine group, Nissl bodies were partly or completely resolved. In 20 mg/kg tetramethylpyrazine group, the quantity of Nissl bodies was significantly increased as compared with those in penicillin-induced epilepsy group and the 10 mg/kg tetramethylpyrazine group. In 40 mg/kg tetramethylpyrazine group, the quantity and the structure of of the average absorbency of stained Nissl bodies in external granular layer cells and external pyramidal layer cells in rat cortex among all the groups.In penicillin-induced epilepsy group, the average absorbency were dramatically lower than that in control group (0.033±0.002, 0.756±0.035, t=4.93,P ＜ 0.01). In 20 mg/kg tetramethylpyrazine group and 40 mg/kg tetramethylpyrazine group, the average absorbency were significantly higher than that in penicillin-induced epilepsy group (0.435±0.011, 0.658±0.029, t=2.98,5.32, P ＜ 0.01). In 40 mg/kg tetramethylpyrazine group, the average absorbency were similar to that in control group (t=1.75, P ＞ 0.05).CONCLUSION: Tetramethylpyrazine can significantly elevated the concentration of Nissl bodies of neurons in rats with epilepsy. Changes in the structure and quantity of Nissl bodies of cerebral neurons may be closely associated with seizure, and tetramethylpyrazine can restore the structure and the quantity of Nissl bodies of neurons, regulate their functions and hereby, inhibit seizures.

Objective To define a suitable and adequate sample volume for the detection of bacterial contamination in cord blood (CB) via BacT/ALERT system. Methods A total of 1 376 cord blood units were routinely screened for aerobic and anaerobic microorganisms by culturing the erythrocyte fraction(EF) or plasma fraction(PF) with 20 ml and 10 ml sample volume. The microbial contamination was detected by BacT/ALERT 3D system, and the results of this method were compared with the improved Martin/thiogly collate broth(22 ℃) and thioglycollate broth(35 ℃).Results The rates of positive BacT/ALERT results were 1.16%(10 ml) and 1.24%(20 ml) for PF, and 3.20%(20 ml) for EF. The positive rate of Martin/thiogly collate broth(22 ℃/35 ℃) was 1.00% for EF. Conclusion Using BacT/ALERT system for microbial detection in cord blood bank can enhance the security of umbilical cord blood transplantation.

Objective To explore the effect of percutaneous transhepatic gastric variceal embolization joint partial splenic embolization on hemodynamic of portal vein.Methods 54 cases who were clinically diagnosed as cirrhosis with portal hypertension,do the treatment percutaneous transhepatic gastric variceal embolization combined with partial splenic embolization.The preoperative and postoperative free portal vein pressure(FPP) were measured by portal vein intubation,and the preoperative and postoperative portal vein(PV),spleen vein(SV) in hemodynamic changes were compared between color dopplar ultrasound and CT scan scanning.Results Free portal vein pressure were significantly increased after percutaneous transhepatic gastric variceal embolization [(37.05 ± 4.27) cm H2O vs (42.60 ± 5.04)cm H2 O,P ＜ 0.01],and reduced through continuing to partial splenic embolization.In the end there were no statistically significant differences (P ＞ 0.05).After 3 months portal venous blood flow and inner diameter and blood flow velocity only is a little change,but spleen vein inner diameter,blood flow velocity and blood flow were decreased significantly(P ＜ 0.01).Conclusion Only percutaneous coronary arteriovenous embolization can increase portal vein pressure,but which joint partial splenic embolization does not affect the thange of portal venous blood flow dynamics.

Objective To assess the efficacy and safety of multimodal analgesia with different doses of nalbuphine combined with flurbiprofen on patients who received intravenous patient -controlled analgesia(PCIA) after thoracotomy.Methods Sixty patients underwent thoracotomy,ASA Ⅰ -Ⅱ,18 -65 years old,who underwent postoperative PCIA,were randomly divideded into three groups according to the digital table,nalbuphine 60 mg group (N60 group),nalbuphine 80 mg group(N80 group)and nalbuphine 100 mg group (N100 group),20 cases in each group.All patients were given 150mg flurbiprofen,a total of 100mL.PCIA solution:the background dose was 2mL/h, PCIA dose of 0.5mL,locking time of 15min.10min before surgery,each patient was intravenously given flurbiprofen 50mg,given a loading dose of 0.1mL/kg when closed chest.All patients were followed up for 48h.The incidence of adverse reactions such as vital signs,number of times,visual analog scale(VAS)score,sedation score,nausea and vomiting were recorded.Results There were no significant differences in the age,gender,body mass index and surgery duration among the three groups(all P >0.05).The vital signs were stable within 48h after operation.The VAS scores of N60 group were higher than the other two groups(N80 group:t =7.94,6.35,6.49,5.21,5.63,all P =0.00;N100 group:t =8.41,9.10,5.80,8.07,8.18,all P =0.00)at 4,6,8,24 and 48h after operation(all P <0.05).The VAS score of N80 group 48 h after operation was lower than that of N100 group(t =2.30,P =0.03),and the difference was not statistically significant in remaining(all P >0.05).The effective /actual compression ratio of PCIA of N80 group and N100 group were significantly higher than that of N60 group (t =7.30,8.35,all P <0.05). There were no differences in the incidence of adverse reaction among the three groups(group N80:χ2 =0.17,0.23, 1.03,all P >0.05;group N100:χ2 =3.14,0.23,1.03,all P >0.05).Conclusion Postoperative PCIA with nalbu-phine (80 mg)combined with flurbiprofen(150 mg)has significant analgesic effect and lower costs.

OBJECTIVE:To investigate the current situation of anticoagulant therapy for patients with non-valvular atrial fibril-lation,and to provide reference for standardized anticoagulant therapy. METHODS:A total of 1056 patients with non-valvular atri-al fibrillation were collected from our hospital during Jul. 2015-Jun. 2016. According to 2012 European Society of Cardiology Guide-lines for the Management of Atrial Fibrillation,the risks of thrombosis and hemorrhage were evaluated,and the standardized anti-coagulant therapy was also evaluated. RESULTS:Among 1056 patients with non-valvular atrial fibrillation,the number of patients with thrombosis risk score ≥1 was 1028,accounting for 97.3%. 763 patients received antithrombosis therapy,and only 139 pa-tients were given warfarin anticoagulant therapy. The international normalized ratio(INR)of prothrombin time in just 30.9% of pa-tients receiving warfarin was in line with the standard before discharge. CONCLUSIONS:The anticoagulant therapy for patients with non-valvular atrial fibrillation is still not optimistic,and effective measure should be adopted to improve the standardization of anticoagulant therapy in the patients with atrial fibrillation.
