ObjectiveTo explore the change of the concentration of monoamine neurotransmitters in serum in patients with post stroke depression(PSD).Methods85 patients with acute stroke were screened by Center for Epidemiological Survey,Depression Scale(CES-D) and assessed by Hamilton Depression Scale(HAMD).A clinical diagnostic of depression was made based on Diagnostic and Statistical Mannal of Mental Disorders,edition 4(DSM-Ⅳ).There were 34 patients who involved with depression(PSD group), the others(51 cases) not(no depression group).Other 20 normal persons were chosen as a control(control group). In all patients and control subjects, the concentrations of monoamine neurotransmitters in serum was measured.ResultsThe concentration of monoamine neurotransmitters in serum was significantly lower in patients with post stroke depression.ConclusionsPost stroke depression is related to decrease of concentrations of monoamine neurotransmitters in serum.

Orthogonal descriptors is a viable method for variable selection, but this method strongly depend on the orthogonalisation ordering of the descriptors. In this paper, we compared the different methods used for order the descriptors. It showed that better results could be achieved with the use of backward elimination ordering. We predieted Rf value of phenol and aniline derivatives by this method, and compared it with classical algorithms such as forward selection, backward elimination, and stepwise procedure. Some interesting hints were obtained.

Objective:To compare the healing of gingiva after electrosurgical gingivectomy with different power outputs and electrodes. Methods:15 rabbits were randomly assigned to 3 groups which used different electrodes: needle electrode, long loop electrode and loop electrode. 1 animal was chosen as control in each group. Free gingiva of anterior teeth had been removed 2 mm in height with different power output and electrosurgical knife. Gingival specimens were harvested for histopathological study on days 1,7,14,and 21 after operation. Statistical analysis was performed on wound healing. Results:Electrical knife with medium power output caused significantly higher degree of inflammation than other techniques(P0.05). Conclusion:When electrosurgery is used on gingiva, there is no significantly difference with different electrodes. Longer observation is needed after gingival electrosurgery with medium power output electrical knife.

To study the effect of nursing intervention on the incidences of complications caused by intracerebral hemorrhage. Methods One hundred and fifty two inpatients of intracere-bral hemorrhage were randomly divided into nursing intervention group and control group. The effects of the two groups were compared. Results The control group was higher than the nursing intervention group on the incidences of complications in constipation and hypostatic pneumonia and the average inpa-tient days(P

From members in this local district from January 2011 to December 2013,a total of 150 patients with malignant cancer and chronic disease patients of lost of functions and their carers were recruited.A self-tailored interview was conducted via face-to-face communications.And according to 112 (74.7％) carers,as compared to hospitalization,the patients were more likely willing to be looked after at home.The 95 (63.3 ％) carers had a lack of professional caring knowledge and their caring techniques were insufficient.And 97 (64.7％) carers were willing receive professional training in nursing and protecting dying patients.In-house terminal care is indeed required by the patients.However its service is best supported by the following aspects.The supports from local medical services and resources; professional training organized by a local social (neighborhood) committee and providing the guidance of in-house caring techniques and information of the relevant disease management.Building up a mutual terminal care group and finalizing the caring standards as soon as possible are essentials.

Objective To purify AmpC beta-lactamase from Enterobacter cloacae and study its physical and chemical characteristics.Methods The bacteria were fragmentized by ultrasonication and AmpC beta-lactamase was purified by ion-exchange.The properties of the purified enzyme,such as molecular weight and isoelectric point were determined by electrophoresis.Results The purified AmpC beta-lactamase was obtained and its specificity to substrate was sufficient for classification of class C cephalosporinase.Conclusion AmpC can be successfully purified from Enterobacter cloacae and is effective for application.

OBJECTIVE: Probe into the causes of postoperative delayed hemorrhage of low temperature plasma tonsillectomy in children. METHOD: The methods of retrospective analysis the difference of postoperative bleeding time and bleeding rate between tonsillectomy by the low temperature plasma and the traditional cold surgical devices in 2-14 years old children. Plasma group contained the tonsillectomy by low temperature plasma between the March in 2012 to the August in 2013. Traditional group contained the tonsillectomy by traditional cold surgical devices between the March in 2005 to the August in 2006. RESULT: In the 1,000 cases of plasma group, 19 cases occurred postoperative hemorrhage, the hemorrhage rate was 1. 9%. Four cases occurred postoperative primary hemorrhage in 8 hours after operation, the postoperative primary hemorrhage rate was 0. 4%. Fifteen cases occurred postoperative delayed hemorrhage, the delayed hemorrhage rate was 1. 50%, the bleeding time was 2-13 days after operation, the average number was 7. 5 days. Nine cases had wound infection and 6 cases had eaten some food improperly in these 15 cases. And in these eaten improperly cases, 4 children had eaten fruit and hard food, 2 children had eaten a little food who lost their weight. In 860 cases of the traditional group, 29 cases occurred postoperative hemorrhage, the hemorrhage rate was 3. 37%. 26 cases occurred postoperative primary hemorrhage in 8 hours after operation, the postoperative primary hemorrhage rate was 3. 02%. Three cases occurred postoperative delayed hemorrhage, the delayed hemorrhage rate was 0. 35%, the bleeding time was 2-6 days, the average number was 4 days. CONCLUSION It is preferable for chileren to having low temperature plasma tonsillectomy. The causes of postoperative delayed hemorrhage of low temperature plasma tonsillectomy in children are probably related to the postoperative infection, the differences of operation skills, the method of stop bleeding, eating the wrong foods, irritating cough, improper nursing and so on.
