Objective To explore the dynamic changes of neuron-specific enolase (NSE) and myelin basic protein (MBP) in serum of rats with temporal epilepsy (EP) induced by kainic acid (KA) and to judge the degree of injury of brain neuron and nerve myelin after seizure.Methods KA was injected into rat's hippocampus by stereotactic operation to establish an animal model of temporal EP.The levels of NSE and MBP in serum of rats with temporal EP were measured at the time 3 h,6 h,12 h,24 h,48 h and 72 h after seizure.Results The level of NSE in serum increased gradually and reached its peak at 24 h after seizure, as well as MBP at 72 h.Conclusions There are the nerve cell damage and necrosis after seizure in rats with temporal EP, then brain white matter nerve myelin appear to damage.

Acetaminophen(AAP)-induced hepatic injury is one of the common causes of drug-induced hepatic injury.Up to date,the mechanisms of AAP-induced hepatic injury are still incompletely understood.Recent advances suggest that reactive metabolite formation,glutathione depletion,alkylation of proteins,especially mitochondrial proteins and peroxynitrite formation are critical initiating events for the toxicity.This review will focus on more recent advances in mitochondrial dysfunction after AAP overdose.Additional,oxidative stress and inflammatory mediators are also important for the overall outcome.

Objective To investigate the clinical features, brain imaging significance and the possible pathogenesis of posterior reversible encephalopathy syndrome (PRES) in childhood acute lymphoblastic leukemia (ALL) followed by chemotherapy induction.Methods The diagnosis and treatment of ALL were performed according to the guidelines of the Pediatric Association of Chinese Medical Association.There were 11 cases of pediatric ALL who developed PRES after chemotherapy induction.The clinical presentations, initial and follow-up radiologic features, and the neurologic outcomes of these 11 cases were investigated for one-year follow-up.All patients were reexamined 1,3,6, and 12 months after first imaging.Results Headache (10/1 1 cases), epileptic seizure (7/11 cases), high blood pressure (4/11 cases) ,visual impairment (6/11 cases) ,disturbance of consciousness (5/11 cases) and walking instability (2/11 cases) were the most common symptoms of these ALL patients with PRES.Magnetic resonance imaging (MRI) scanning revealed that lesions were mainly distributed in occipital lobe (9/11 cases), parietal lobe (8/11 cases), frontal lobe (5/11 cases) ,temporal lobe (3/11 cases), the deep white matter of bilateral periventricular and centrum semiovale (2/11 cases) and hemisphaerium cerebelli (1/11 cases).The radiological findings indicated that lesions had multifocal,symmetrical and posteriorly distributed characteristics in the cerebral hemispheres.After the diagnosis of PRES,patients stopped chemotherapy courses promptly and received symptomatic treatment, and then the clinical and imaging symptoms of most cases gradually disappeared.After 1-year follow-up,9 patients had good prognosis and no sequelae, 1 patient had symptomatic epilepsy (brain magnetic resonance imaging scan showed lesions in the left temporal lobe) ,and 1 patient had slight visual impairment.After the craniocerebral symptoms disappeared clinically ALL chemotherapy continued in all patients and no recurrent PRES was observed.Conclusions Although the clinical and imaging features of PRES may be diverse ,PRES should be recognized as a possible important complication of ALL when neurological symptoms appear.However, PRES is reversible when the patients are diagnosed and treated at an early stage.Thus,the occurrence of PRES should be considered and investigated to optimize the early induction schemes for ALL treatment.

Objective To study the possible effects of transcranial magnetic stimulation (TMS)on the sleep structure of the patients with Parkinson's disease.Methods Fifteen PD patients attending an outpatient Movement Disorders Unit at Department of Neurology,Cerrahpasa Faculty of Medicine,between September 2006 and December 2007 were included in the study.All patients had received TMS treatment.The stimuli were delivered through a circular coil with a 12 cm diameter and a 2.0 T peak magnetic field.They underwent clinical evaluation and polys omnographic (PSG) evaluation before and after a minimum treatment period of 10 days with TMS.Results The mean UPDRS score was significantly decreased after TMS(before treatment,38.83?16.72;after treatment,25.09?11.10).PSG revealed that administration of TMS resulted in significant decrease in mean Sleep latency[before treatment,(53.50?46.40)min;after treatment,(30.43?23.91)min].Slow wave (stage 3+4) was found in somes patients after treatment.But here was a trend towards an decrease in Percentage of stage 1,REM latency and REM sleep without significance.Conclusion This study demonstrates that motor symptom of PD was improved and Sleep latency was decreased by TMS.Sleep structure was not changed before and after TMS treatment.

Thirty-six male adult rats were divided into 12 groups. The rats, except the control group, were partially (68％) hepatectomized and then killed at intervals between 12-120h after operation. Isolated hepatocytes were prepared and flow cytometry was used to study the proliferative cycle. Mitotic index and binuclear cell count have been performed in liver sections and smears of isolated hepatocytes separately. Tetraploid cells acounted for 76% of all hepatocytes in normal rats and they also constituted the main proliferative population in regenerating liver. During 12-20h after operation, some of the tetraploid cells that remained in G_2 phase entered into mitosis. At 24h after operation, peaks of S phase in tetraploid cells and of octoploid cells occurred. At 36h after operation, mitotic index reached a maxium value and thereafter the percentage of binuclear cells were reduced rapidly. At 48-72h after operation, second peak of DNA synthesis occurred, but showed wide individual variations in time and cell proportion.

OBJECTIVE:To evaluate the effects of quality control circle(QCC)in improving the compliance of asthma/COPD outpatients handling inhaler devices. METHODS:By simple random sampling method,90 asthma/COPD outpatients receiving Tiotropium bromide powder for inhalantion,Salmeterol xinafoate and fluticasone propionate powder for inhalantion and Budesonide and formoterol fumarate powder for inhalantion were selected from our hospital during Apr. to Nov. 2015. The reasons for poor com-pliance of handling inhaler devices were analyzed by QCC. The countermeasures were formulated to improve the compliance,in-cluding clinical pharmacist education,follow-up,issuing education manuals,developing WeChat consulting. Operation step score of inhaler devices,compliance score and activity ability score of QCC members were analyzed statistically before and after QCC. RESULTS:After the development of QCC,operation step score of inhaler devices and compliance score in 90 asthma/COPD outpa-tients increased from 7.7 and 7.7 before activity to 8.8 and 9.3 after activity,the achievable rate of compliance was 114.3%,and the improvement rate was 20.8%. The sense of honor,responsibility,self-confidence,QCC techniques,communication and coordi-nation,team cohesion of all members were all improved obviously. CONCLUSIONS:QCC activity improves the compliance of asthma/COPD outpatients handling inhaler devices and shows the professional service level of clinical pharmacists,which is of sig-nificance to the improvement of pharmaceutical care.

Objective To investigate the effect of comprehensive nursing intervention on the quality of life of patients suffering from hypertension. Methods A total of 120 cases of essential hypertension were evenly randomized into observation group and control group. Both groups received conventional antihypertensive drug and nursing, and additionally, the observation group was given intervention of comprehensive nursing including dietary regulation, exercise training, emotional care and medication instruction. The intervention lasted 3 months. Before and after the intervention, traditional Chinese medicine ( TCM) symptom classifying list and World Health Organization ( WHO) QOL-BRIEF were applied to evaluate the therapeutic effect of the two groups. The changes of blood pressure, clinical manifestation and the quality of life were also compared between the two groups. Results (1) After intervention, the systolic pressure and diastolic pressure were both improved in the two groups ( P<0.05 or P<0.01 compared with those before treatment) , and the improvement in the observation group was superior to that in the control group (P<0.01). (2) After intervention, the scores of TCM symptom scores and QOL-BRIEF total scores were improved in the two groups ( P<0.05 or P<0.01 compared with those before treatment) , and the improvement in the observation group was superior to that in the control group ( P<0.01). Conclusion TCM comprehensive nursing intervention can effectively relieve hypertension and improve the quality of life of hypertension patients.

Objective To investigate the clinical efficacy of auricular point therapy for chronic fatigue syndrome.Methods Eighty patients with chronic fatigue syndrome were randomly allocated to treatment and control groups, 40 cases each. The treatment group received ear acupuncture plus auricular plaster therapy and the control group, conventional acupuncture. The overall symptom was scored, the Fatigue Assessment Instrument (FAI) score was recorded and immunoglobulins (IgA, IgG and IgM) were measured in the two groups before treatment and after four courses.Results There were statistically significant pre-/post-treatment differences in the overall symptom score, the FAI score and immunoglobulins in the two groups (P<0.05). There were statistically significant post-treatment differences in the FAI score, and IgA and IgG between the treatment and control groups (P<0.05). Conclusion Auricular point therapy is an effective way to treat chronic fatigue syndrome.

Objective To study the effects of repeated transcranial magnetic stimulation(rTMS)on Parkinson's plus syndrome(PPS).Methods Fifteen in-patients with PPS were studied between 2005 and 2008.The patients received 1 Hz rTMS at an intensity 30%over the threshold.The rTMS was applied on the hand representive area of the bilateral first motor cortex,50 stimulations on each side,5 arrays,for 5 min,once daily for 15 d.Hamilton's depression scale(HAMD),Hamilton's anxiety scale(HAMA),the unified Parkinson's disease rating scale(UPDRS,which can be subdivided into UPDRS Ⅰ,UPDRS Ⅱ and UPDRS Ⅲ),an activities of daily living scale(ADL),the mini-mental state examination(MMSE)and motor evoked potential(MEP)were assessed before and immediately after 15 d of rTMS treatment. Results Average HAMD,HAMA,UPDRS,UPDRS Ⅱ and UPDRS Ⅲ scores all decreased,and ADL scores increased significantly after treatment,while UPDRSⅠand MMSE scores were unchanged before and after treatment.No significant changes in resting motor threshold or central motor conduction time of the MEP were observed after rTMS treatment. Conclusion Clinical symptoms of PPS patients improved after rTMS treatment and side effects were few.Depression,anxiety,motor function and ability in the activities of daily living improved greatly.Repeated transcranial magnetic stimulation is a potential treatment for PPS patients.There may be no correlation between the effective mechanism of rTMS and cortex excitation.
