OBJECTIVE:To explore the new mode and new method for the teaching work mode of clinical pharmacists in phar-maceutical ward rounds. METHODS:Medicine comprehensive ward rounds mode centered by teachers and independent pharmaceu-tical rounds interrogation mode centered by clinical pharmacist trainees were respectively tried by clinical pharmacists to guide clini-cal pharmaceutical cares. Three-level mode of medical rounds was used for reference. Teaching rounds by trainees,teaching staff and teachers were tried to train the learning and practice ability of different levels of trainees. RESULTS & CONCLUSIONS:Ac-cording to the different forms of exploration of teaching work mode in pharmaceutical ward rounds,trainees,teaching staff and teachers has practiced and improved in the pharmacy professional practice skills. Pharmaceutical ward rounds are the important parts of work,and different teaching modes are significant for the advanced quality of trainees.

The substantia gelatinosa of subnucleus caudalis of the trigeminal nerve of the rat shows an intense extralysosomal acid phosphatase activity which disappears after the removal of it's skin of the facial regions.Different regions of the facial skin of 69 rats were excised and the projections of the cutaneous nerves were traced by studying the extralysosomal acid phosphatase activity with the modified Gomori's methods.A somatotopical localization was found within the substantia gelationosa. It agreed with what has been found in earlier studies where other techniques have been used. The findings showed that the fibers of the cutaneous areas along the dorsoventral axis of the body were found in a reverse order in the receptive fields in the substantia gelatinosa. The vertex and fore-head lay in the ventral, while skin of the mandibular areas in the dorsal region, and the skin of the facial areas lay successively from ventral to dorsal in following order: vertex and forehead eye region, dorsal vibrissae, ventral vibrissae-upper lip and finally lower lip-mandibulare region, in the receptive fields of the substantia gelatinosa.The cutaneous facial regions were disproportionately represented in substantia gelatinosa, for example, the field receiving projections from the vibrissae areas or fields were as large as 4mm~2 in the most medial portion of the ventral vibrissae-upperlip which are disproportionately large while the fields receiving projections from the forehead and mandibular cutaneous regions were disproportionately small. The provides a possible explanation for the specific function of analgesia of the acupuncture point Renzhong.

Objective: To explore the protective effect of Shenmai lyophilized preparation (SMP, 参麦冻干剂) on acute myocardial infarction (AMI) in cats. Methods: AMI cat model was induced by ligation of the left coronary artery for 4 hours. Cats were randomly divided into five groups: AMI group (4 ml/kg of normal saline ), large dose SMP group (1.76 g/kg), small dose SMP group (0.88 g/kg), Shenmai injection (参麦注射液) group (0.88 g/kg) and nitroglycerine group (0.44 mg/kg). Drugs were given 5 minutes after the left coronary artery ligation. Mean arterial pressure (MAP) and ventricle cardiac arrhythmia were monitored by multichannel biological signal analytical system. MultiCD*2lead ?ST on chest was recorded by cardiofax after myocardial ischemia for 4 hours, the area of AMI was measured by dyes with triphenyl tetrazolium chloride (TTC). Changes of creatine kinase (CK) and lactate dehydrogenase (LDH) in serum were assayed by colorimetric assay. Results: SMP at the dosage of 0.88 and 1.76 g/kg increased MAP, decreased ?ST and incidence of ventricle cardiac arrhythmia in cats with AMI, shrank the area of AMI and decreased the LDH content and CK activity in serum, respectively compared to the AMI group, the differences being significant in the aboveCD*2mentioned parameters (P

The peripheral nerves supplying the acupuncture points of the facial regionwere sectioned from 63 rats and their central terminations were traced by the loss ofthe acid phosphatase(ACP)activity in the substantia gelatinosa(SG)with themodified Gomori's method.1)The supraorbital nerve was cut,the loss of the ACP was confined to thelateral aspect of the substantia gelatinosa in spinal segments C_1.2)The infraorbi-tal nerve was transected,the ACP activity was absent from the central and lateralsectors of the SG in the medulla oblongata.3)The mental nerve was divided,theACP activity was absent from the most medial sector of SG in the medulla oblon-gata and C_1.4)The auriculotemporal nerve was severed,the activity of the enzymewas absent mainly in the inner medial sector of SG in the C_1 and C_2.5)Thefacial nerve was divided,the area deprived of enzyme activity is mainly found inthe central medial sector of SG in C_2.6)The vagal nerve was divided,a medialsector or central sector of SG in the C_1 and C_2 segment is devoid of ACP.7)Thegreat auricular nerve and the cutaneous cervical nerve were severed,the ACP activitywas absent in SG of the upper four cervical cords.The above results show that the primary sensory nerve of the peripheral nerveswhich supply the facial acupuncture points terminate in the SG of the subnucleuscaudalis of the trigeminal nerves and the dorsal horn and the primary sensory nervefibre of these nerves mostly terminate in C_1 and C_2 segment.

Objective To elucidate whether down-regulation of homo sapiens eukaryotic translation elongation factor 1 alpha 2 (EEF1A2) expression induces apoptosis in pancreatic cancer cells and its possible mechanisms. Methods Two siRNAs targeting human EEF1A2 were synthesized and the siRNA/liposome complexes were transfected into the pancreatic cancer cell line BxPC-3. RTPCR and Western blot were used to analyze the change of EEF1A2 expression and the apoptosis rate of BxPC-3 cells was studied using Annexin-V/PI assay. To identify the mechanisms involved, the apoptosis associated proteins such as caspase-3, caspase-8, caspase-9, PARP, cytochrome C and Bid were detected by Western blotting. Results Both EEF1A2-targeting siRNAs reduced the EEF1A2expression, and the No. 2 siRNA inhibited EEF1A2 expression to less than 25 % in mRNA and protein levels. Down-regulation of EEF1A2 expression in BxPC-3 cells enhanced cell apoptosis (15.28% ±3.65%) at a greater level than negative siRNA-expressing cells (10. 11% ± 3. 05%) or mock cells (9.41 % ±4.14 %). Furthermore, reduction of EEF1A2 activated the pro-caspase-8, pro-caspase-3,pro-caspase-9,PARP and Bid to their active forms, and increased the expression of cytochrome C.Conclusions These data suggest that EEF1A2 down-regulation could significantly induce apoptosis of pancreatic cancer cell line BxPC-3, which is likely mediated by the death receptor and mitochondrial apoptotic pathways.

Objective To studythe role of p16 and cyclin in the genesis and development of endometrial car-cinoma. Methods 12 cases of normal endometrium, 22 cases of proliferative endometrium and 41 cases of endome- trial carcinoma were detected for the expression of p16 and cyclin D1 by means of immunohistochemical S-P. Results In normal endometrium p16 was expressed while cyclm D1was almost negative in the proliferative phase, but both of them were negative in the secretory phase. Among the groups of the simple and compound hyperplasia, the atypical hyperplasia and the endometrial carcinoma,the expression of p16 showed a descending tendency, while the expression of cyclin showed an ascending tendency. In endometrial carcinomas the expression of p16 was significantly lower than that of normal endometrium and proliferative endometrium (P<0. 01 ,P<0.05). However, the expression of cy- clin in proliferate endometrium and endometrial carcinoma was significantly higher than that in normal endometri- un (P<0. 05,P<0. 01). The overexpression of cyclin D1 in the atypical hyperplasia group was obviously different from that in the simple and compound hyperplasia group (P＜0.01). In endometrial carcinoma,the expression of p16 was decreasing with the descending of cell differentiate degree, on the opposite, the expression of cyclin was in-creased and there existed a negative correlation between them. It was also observed that the overexpression of cyclin was significant different between and ( P ＜0. 01 ). Conclusionp1 6 is a negative regulating factor of cell cycle in endometrial carcinoma, while cyclin is a positive one. Both of them are important in the genesis and devel-opment of endometrial carcinoma. The Iow expression of p1 6 and the overexpression of cyclin are related with the malicious biological behaviors of endometrial carcinoma and maybe play an important role in the judgement of prog- nosis. Overexpression of cyclin may be an earlier molecular event in the genesis of endometrial carcinoma.

Objective To evaluate the factors influencing prognosis and to explore the pathological mechanism in which herpes simplex virus encephalitis(HSE) was one of the severe types of acute viral encephalitis in children and had poor prognosis.Methods Twenty-one children with HSE were diagnosed by the clinical syndrome of focal encephalitis and HSV DNA-PCR positive in cerebrospinal fluid(CSF) from Jan.2012 to Oct.2013,among whom,19 patients were treated with intravenous Acyclovir,30 mg/(kg · d) 48 hours after onset and were followed up for 6 to 24 months.Clinical data were collected including Glasgow Coma Score,the brain magnetic resonance imaging(MRI),and electroencephalography(EEG).All MRI examinations including plain scan and contrast enhancement were carried out at the beginning of admission and 1 month after the onset of symptoms.The clinical outcomes were divided into two levels accoming to the severity of the neurological deficit,then the data were analyzed by using Logistic regression and Fisher's exact probability method.The OR value was calculated.Results Eighteen children survived,of whom 5 cases had no neurological deficit(27.8％),3 cases were left with mild impairment(16.7％),and the above 8 cases were thought to have better outcome.Six cases had moderate impairment (33.3％) and 4 cases had severe impairment(22.2％) and 1 child died,and these 11 cases were thought to have worse outcome.Patients aged between 1 month and 10 years,average (2.03 ± 2.23) years old.The mean GCS score was (9.68 ± 2.65) scores,the GCS of the patients were more than 7except for one death child with 3 scores.The multiple factor analysis showed that EEG,age,GCS and the range and character in MRI were significantly correlative to the prognosis(P ＜ 0.05).The single factor analysis illustrated that age 1-4 years old(OR =30,95％ CI 2.066-366.510,P =0.002),GCS ≤ 10 scores(OR =27.518,95％ C1 2.066-366.510,P =0.004)and the wide necrosis existence involving diffuse white matter or deep nuclei of MRI findings (OR =12,95 ％ CI 1.294-111.323,P =0.017) indicated the worse outcome.Conclusions Age,GCS score,nature and damage degree of MRI lesions are the main important factors affecting the prognosis of children's HSE.HSE in children is apt to involve the cortex such as frontal lobe,parietal lobe even diffuse white matter or deep nuclei,which indicates the poor prognosis.
