Objective To investigate the preventive action of Gongxuening capsule combined with oxytocin in treatment of bleeding after medical abortion.Methods 71 casess with medical abortion from March 2014 to May 2015,were randomly divided into observation group of 34 patients and control group of 37 patients.Conventional medical abortion forpregnant women as a control group, giving Gongxuening capsule drug for pregnant women in observation group.After medical abortion, the efficacy of the drug flow between two groups of patients, pregnant women, complete abortion drug flow vaginal bleeding, incomplete abortion pregnant drug flow duration and recovery time of menstruation comparative analysis.Results After medical abortion,medical abortion effect of the two groups of pregnant women were analyzed, the results showed that the proportion of complete abortion patients in the observation group, the proportion of incomplete abortion, abortion failure rates and the control group was not significant.Vaginal bleeding after two complete abortion drug flow comparing pregnant women in observation group and less than an amount equal to the total number of menstruation was significantly lower than control group (χ2 =5.318,P<0.05).Observation group after the drug flow vaginal bleeding lasted significantly phrases in the control group (P<0.05); the recovery time of menstruation after medical abortion were compared two groups of patients.Observation group completely abortion menstrual period the number of days than the control group (P<0.05);similar to the menstrual cycle days, the difference was not statistically significant.Conclusion Gongxuening capsule combined with oxytocin on bleeding after medicinal abortion has a significant preventive effect, can effectively reduce the amount of bleeding and bleeding time in patients after the drug flow, which is a safe and effective medical abortion methods should be promoted and used in clinical.

Objective To estimate the curative effect and cost-effectiveness of moxifloxacin and gatifloxacin for treatment of urinary traet infection. Methods Eighty patients with urinary tract infection were randomly divided into treatment group (40 cases) and control group (40 cases). The patients in treatment group were given 400 mg moxifloxacin once a day for 7 d, while in control group were given 400 mg gatifloxacin once a day for 7d. Results The total clinical effective rate of treatment group and control group were 95.0%(38/40) and 92.5%(37/40) respectively, and the bacterial eliminating rate were 77.50% (31/40) and 76.92% (30/39), and the rate of adverse reaction were 5.0% ( 2/40 ) and 7.5% (3/40) respectively. There was no significant difference between two groups (P>0.05). The cost-effectiveness ratio of moxifloxacin was 2296 and 779 for gatifloxacin (P<0.01). Conclusion The therapeutic scheme of gatifloxacin seems to be the best one for treating urinary tract infection.

Objective To explore the intervention effect of cathepsin B inhibitor (CBI) and its signaling pathways after flurothyl inducing brain injury in rats with recurrent seizures. Methods 6-day-old (P6) SD rats were randomly divided into: recurrent neonatal seizure group ( RS group, n = 30), CBI-treated seizure group ( CBI group, n=30) and the control group( CONT group). Rats in RS group were subjected to 5 seizures with flurothyl during the first 14 days of life. In CBI group,CBI was injected each day before seizures were induced. Then examined development indexes such as the physical growth, neural reflex, neural behavior and cognitive emotional competence. Western blot was employed to determine Cathepsin B expression at different time points ( 1.5h,3h,6h,24h and P35) after the last convulsion. Results The weights of rats in RS group( (27.28 ± 1.6) kg) were lighter than CONT group( ( 33.45 ± 1.57 ) kg). They had significant difference (P＜ 0.01 ) at the age of p14. The time of cliff avoidance in RS group( (2. 10 ± 1.45 ) s) was longer than CBI group( ( 1.05 ± 0. 32) s). It showed a statistically significant (P ＜ 0.05 ) in p12. In the open-field behavior test: the activities of RS group (20.00 ± 13.08 )were markedly reduced than CONT group ( 57.83 ± 33.22 ) in the horizontal movements, the RS group ( 2.50 ±2.43 ) were significantly decreased than the CONT group and CB1 group( ( 22.17 ± 10.74), (9.33 ± 5.39 ) ) in the vertical motions (P ＜ 0. 05 ). Cathepsin-B expression in RS group( 1.5h, 3h,6h and 24h )was significantly higher than that at the same time in CONT group(P＜ 0. 05 ). Cathepsin-B expression of CBI group was significantly decreased compared with that in RS group (P＜ 0. 05 ) at the time point (1.5h ,3h,6h and 24h). There were no significant differences among three groups at P35(P＞0.05 ). Conclusions CBI can improve brain injury and regulate the expression of abnormal molecules.

Objective To explore the dynamic expressions of autophagia and apoptosis associated protein Beclin-1, Cathepsin B and Bcl-2 in hippocampus and the intervention efficacy of cathepsin-B inhibitor (CBI) after recurrent neonatal seizure. Method Ninty 6-day-old SD rats were randomly (random number) divided into the recurrent neonatal seizure group (RS group, n = 30), CBI-treated seizure group (CBI group, n = 30) and the control group (n = 30). Rats in RS group were subjected to 55 attacks of seizure induced by using flurothyl during the consecutive 9 days beginning on the 6 th postnatal day (P6). In CBI group, CBI (2 μL, 0.5 μg/μL) was administered every day before seizures induced. Western blot was employed to determine the protein level at different intervals (1.5 h,3 h,6 h,24 h) after the last convulsion.Results There were higher expressions of Beclin-1 and Cathepsin B, and lower expressions of Bcl-2 expression in RS group(1. 5 h,3 h,6 h and 24 h) than those at the same time in control group (P ＜ 0.05). Beclin1 and Cathepsin B expressions were lower while Bcl-2 expressions were higher in CBI group at the intervals of 1.5 h,3 h,6 h and 24 h compared with those in RS group (P ＜ 0. 05). Conciusions Autophagic and apoptotic pathways were activated immediately after recurrent neonatal seizures as indicated by expression changes of Beclin-1, Cathepsin B and Bcl-2 in hippocampus, which suggests a synergistic effect of the two pathways in the pathophysiology of the long-term brain damage of neonateε resulted from the adverse effects of recurrent neonatal seizures.

Objective To evaluate the effects of amiodarone on connexin43 (Cx43) expression during myocardial ischemia-reperfusion (I/R) in rats.Methods Adult male Sprague-Dawley rats,weighing 250-300 g,were randomly divided into 3 groups (n =12 each) using a random number table:shame operation group (group S),I/R group and amiodarone group (group AM).Myocardial ischemia was induced by occlusion of anterior descending branch of left coronary artery for 30 min followed by 120 min of reperfusion in I/R and AM groups.Amiodarone 5.0 mg/kg was injected intravenously at 10 min before ischemia followed by infusion at a rate of 0.15 mg· kg-1 · min 1 until the end of reperfusion.Arrhythmia was recorded during reperfusion and scored.At the end of reperfusion,blood samples were taken from the femoral artery for determination of the serum levels of cardiac troponin Ⅰ (cTnI) and creatine kinase isoenzyme-MB (CK-MB).Then the animals were sacrificed and myocardial specimens were removed for determination of the expression of Cx43 protein (by immuno-histochemistry) and mRNA (by RT-PCR) in myocardial tissues.Results Compared with group S,the arrhythmia score and serum levels of CK-MB and cTnl were significantly increased,and the expression of Cx43 protein and mRNA was downregulated in I/R and AM groups (P ＜ 0.05).Compared with group I/R,the arrhythmia score and serum levels of CK-MB and cTnI were significantly decreased,and the expression of Cx43 protein and mRNA was up-regulated in group AM (P ＜ 0.05).Myocardial Cx43 was unevenly distributed in group I/R,while evenly distributed in S and AM groups.Conclusion The mechanism by which amiodarone protects myocardium against I/R-induced arrhythmia is related to inhibition of redistribution of Cx43 and up-regulation of Cx43 expression in rats.

This paper introduced a hand function rehabilitation system based on motor imagery (MI) brain-computer interface for hand function rehabilitation of stroke patients. The rehabilitation system contains three subsystems. Offline training subsystem displays the blank screen, a left or right hand movement video and arrow in turn, which respectively reminders patients to rest and make preparations for MI and instruct them how to do MI, and be doing MI. Finally, the patients' electroephalography (EEG) signals are acquired and processed togenerate a recognition model. Model update online training subsystem presents the black screen and a left or right arrow, the meanings ofwhich are the same as those in offline training subsystem. Then the acquired EEG signals are analyzed according to the established recognitionmodel. Next, the analysis result is derived to control the hand movement video to be played. The video can also act as a visual feedback,which makes patients' EEG signals easier to be recognized. The updated and more effective recognition model is built at last. Virtual reality(VR) online training subsystem constructs 3D grid models of VR scene, a 3D man model and its hand animations in the 3Dmax. Then, all ofthem are imported into Unity3D. The control methods of the animations are also designed in Unity3D. In the end, the patients' EEG signalsare analyzed according to the updated recognition model, thus controlling the hand movements of the 3D man in real time. The developedsystem has many characteristics, such as multilevel training and more immersion, which hopefully promotes the plasticity of central nervoussystem. The designed system provides new treatments for post-stroke hand function rehabilitation and further lays the foundation for family-mode rehabilitation.

Objective To investigate the clinical features of patients with brucellosis in Fujian Province and to update the relevant physician's knowledge on brucellosis.Method Retrospective analysis of the epidemiological,clinical,laboratory,imaging,treatment and outcome data of 7 patients with brucellosis were carried out in Fujian Medical University Union Hospital between January 2011 and July 2015.Results Of the 7 patients with brucellosis,6 were males and 1 was female aged between 29 to 61 years old,and 6 cases had a history of contact with goat.The main clinical presentations were repeated limb pain in 6 cases,6 patients got fever,4 cases with hepatomegaly,6 cases splenomegaly,and 7 cases lung inflammation.Hematology examination results indicated that 4 cases were normal,1 case decreased and 2 cases increased in white blood cells.Six cases had a liver dysfunction and 4 cases with low albumin level.All patients were detected positive of Malta Brucella by blood culture or bone marrow culture.In 6 cases and 4 cases out of the 6 cases,splenomegaly and hepatomegaly were found through B ultrasonography,respectively.After treatment of the 7 cases by doxycycline combined with minocycline rifampicin,3 cases were recovered,2 cases were relapsed,and 2 cases were improved.Conclusions The clinical symptoms are typical in these brucellosis patients.What we need to do is focus on improving the clinical and related physician's awareness of brucellosis,collecting a comprehensive history,choosing suitable assistant examinations based on the conditions of patients,strengthening the contact between clinical departments and auxiliary departments,and timely diagnosis.

Objective The study was to compare the effect of sufentanil and morphine preconditioning on ischemia /reperfusion-induced ventricular arrhythmias and the expression and distribution of myocardial Cx43 in rats.The regulation mechanisms that how sufentail and morphine lead to the change of Cx43 were also studied.Methods 32 male SD rats were randomly divided into 4 groups:sham operation group (group C),ischemia/reperfusion (group I/R),morphine preconditioning group(group M) and sufentanil preconditioning group(group S),each group had 8 rats.Established myocardial ischemia/reperfusion model,continuous recorded Ⅱ ECG,mean arterial pressure(MAP) and heart rate(HR).The ventricular arrhythmias at the 30 min before reperfusion was observed and the ventricular arrhythmias score of each group was calculated by ECG analysis; expression and distribution of Cx43 protein were observed by immunohistochemical technique.Results Compared with group C,the HR,MAP,RPP of group I/R were decreased obviously (P ＜ 0.05),while the arrhythmia score was significantly higher(P ＜ 0.05).Compared with group I/R,the extent of the declined of HR,MAP,RPP of group M and group S were eased significantly(P ＜ 0.05) and arrhythmia score was significantly lower(P ＜ 0.05).The HR,MAP,RPP of group M and group S are closer(P ＞ 0.05).Compared with the group C,Cx43 expression level in group I/R was significantly reduced (P ＜ 0.05) and the distribution was disordered,while compared with the group I/R,Cx43 expression level in group M and group S were significantly increased (P ＜ 0.05),and its distribution was structured.In group M and group S,Cx43 expression level were closer(P ＞ 0.05) and so as their distribution.Conclusion Sufentanil and morphine could inhibit the reduction of myocardial Cx43 expression level and improve its distribution which could played an important role in anti-arrhythmic during ischemia-reperfusion.

Objective To examine the gene expression levels of matrix metalloproteinase-1(MMP-1), tissue inhibitor of metalloproteinase-1 ( TIMP-1) in peripheral blood mononuclear cells (PBMC) and sera in the patients with chronic hepatitis B (CHB) and to investigate the value of message RNA(mRNA) expression of MMP-1 and TIMP-1 for diagnosing liver fibrosis. Methods PBMC and sera samples were collected from 37 CHB patients and 20 healthy controls. The total RNA isolated from PBMC was reversely transcribed into cDNA. The mRNA levels of MMP-1 and TIMP-1 in PBMC were examined by real-time fluorescence quantitative reverse transcription polymerase chain reaction (FQ-RT-PCR). The serum levels of MMP-1 and TIMP-1 were determined by sandwich enzyme-linked immunosorbent assay (ELISA). Liver tissues were obtained from all these patients by biopsy and subsequently used for evaluating liver fibrosis stages (S). Intergroup comparison was performed by non parametric test. The correlation analysis was performed by Spearman. Results The MMP-1 and TIMP-1 mRNA levels in PBMC from healthy controls were low. The MMP-1 mRNA levels in PBMC from CHB patients were not significantly different from those in healthy controls,while the TIMP-1 mRNA levels were remarkably higher in CHB patients' PBMC compared to healthy controls. Both the MMP-1 mRNA levels in PBMC and the MMP-1 protein levels in sera were not significantly different among CHB patients at different disease stages and healthy controls (χ~2 =8. 960,P=0.111l ;χ~2 =7. 898, P = 0.211). However, the TIMP-1 mRNA levels in PBMC and the TIMP-1 protein levels in sera increased gradually along with the disease progressed from S1 to S4. The TIMP-1 mRNA levels in PBMC were (1.67±0. 84) lg copy/μL, (3. 48±2. 08) lg copy/μL,(5. 86±3. 47) lgcopy/μL and (8. 14 ± 6. 48) lg copy/μL from stage 1 to 4 respectively, while the protein levels of TIMP-1 in sera were (233. 73±64. 84) ,μg/L, (262. 10±71. 12) μg/L, (301. 15±62. 74)μg/L and(381. 15 ± 152. 75)μg/L, respectively. The differences between each stages were statistically significant (χ~2'= 14. 290, P=0.002,χ~2 = 12.209, P=0. 007). The TIMP-1 mRNA levels in PBMC and the TIMP-1 serum levels were positively correlated with liver fibrosis stage (r=0. 752, P<0. 01;r=0. 530, P=0. 008). Conclusions The TIMP-1 mRNA level in PBMC and TIMP-1 protein level in serum are closely related with liver fibrosis stages. These two parameters, especially the TIMP-1 mRNA level in PBMC, can be potentially new markers for diagnosing liver fibrosis.
