OBJECTIVE:To investigate the cognition,evaluation and demands of medical staff to the clinical pharmacy work in the secondary and tertiary medical and health institutions in Xi’an city,and provide reference for further promoting the develop-ment of the local clinical pharmacy work. METHODS:20 secondary and tertiary medical and health institutions in Xi’an city were randomly selected to conduct a random sampling questionnaire for physicians,nurses (senior nurses),pharmacists (non-clinical pharmacist)and other medical technicians. And the results were statistically analyzed. RESULTS:Totally 1 020 questionnaires were sent out,851 were effectively received with effective recovery of 83.4%. 45.9% respondents knew clinical pharmacy,and“Col-league”was the main channel;34.3% thought clinical pharmacy“only maintained normal operation. 74.7% surveyed medical staff,92.6% surveyed pharmacists and 70.6% surveyed physicians thought clinical pharmacists“should”take round with the doc-tors and nurses;44.3% respondents showed“dissatisfaction”and“general satisfaction”with the clinical pharmacy work in their hospitals. 48.5% respondents would take the initiative to consult the clinical pharmacist for medication;45.5% respondents partial-ly accepted the drug information provided by clinical pharmacists. There were significant differences in the investigation results in aspects of respondents’understanding level and channel for clinical pharmacy,cognition for development situation of clinical phar-macy,evaluation for clinical pharmacists participating round,demand for consulting the medication,acceptance for drug informa-tion provided by clinical pharmacists,and other items(P<0.05). CONCLUSIONS:The cognition and effect of clinical pharmacy work on medical staff need to be further strengthened,clinical pharmacists should also have solid clinical knowledge and the knowl-edge of medicine to meet the demand of medical staff in different positions,the acceptance of medical staff to the pharmaceutical care needs to be further improved. Clinical pharmacists should earnestly fulfill their job functions through various efforts to promote rational drug use.

In order to solve the problem of poor communication, low efficiency of consultation, and even affecting self-confidence caused by unskilled skills and insufficient cooperation with patients in the real clinic, and to solve the problem during the clinical thinking training that beginners do not know how to organize effective information and complete the process of diagnosis and differential diagnosis more efficiently. By applying the artificial intelligence (AI) virtual patient (VP) system to the process of teaching diagnostic knowledge and clinical thinking training. It provides the students with the experience of simulating the diagnosis and treatment of the clinical real scene. Let the students talk with the VP system for inquiry training and then go to the clinic to give the real patients inquiry and by simulating the process of treating the real patients, let the students take the initiative to complete the collection of medical records and clinical decision-making under the simulated scene to train the clinical thinking. This can not only solve the shortcomings of the previous simulation teaching and clinical teaching, but also stimulate students' interest in learning. According to the results of the questionnaire, students have a high acceptance of VP system simulation teaching. Through the results of homework and assessment and evaluation, the teaching results are better than before, and this teaching method should be further popularized.

Objective To investigate the effect of neuropeptide Y (NPY) on the osteoblastic differentiation of murine MC3T3-E1 cells and its mechanism related to the Wnt signaling pathway.Methods The murine MC3T3-E1 cells were divided into 4 groups according to the stimulators added:phosphate buffered saline (PBS) (control) and different concentrations of NPY (10-8 mol/L,10-10 mol/L and 10-12 mol/L).The cellular proliferation was detected with MTT assay after 1,3,5,7 and 9 days.The cells were identified with cell immunochemistry and Western Blot to find out the most effective concentration of NPY at different time points under osteoblastic condition.The cells were then divided into 4 groups:PBS,NPY,NPY + NPY receptor antagonist,and NPY + DKK1.Western blot was used to determine the expression of β3-catenin and p-GSK-3β in each group.Nuclear signaling activity of β3-catenin was observed using immunofluorescence staining.Results NPY significantly improved the proliferation of MC3T3-E1 cells at 7 and 9 days (P ＜0.05).NPY (10s mol/L and 10-10 mol/L) groups and NPY (10-10 mol/L and 10-12 mol/L) groups significantly improved the ALP activity at 4 and 14 days respectively (P ＜ 0.05).At 4 days,the expression of ALP protein was significantly decreased in the NPY + DKK1 group and the NPY + NPY receptor antagonist group compared with that in the NPY group (P ＜ 0.05).Although the expression levels of [β-catenin and p-GSK-3β protein were uninfluenced in either case,NPY significantly stimulated the nuclear signaling activity of β3-catenin.Conclusions NPY may significantly increase the expression of ALP protein in MC3T3-E1 ceils during osteoblastic differentiation.This effect might be mediated through the canonical Wnt signaling pathway.

Aim To observe the effect of pyrimidine dithiocarbamate (PDTC) on the variance of disc morphology and the expressions of TNF-α, MMP-9 in the cervical disc in cervical dynamic equilibrium rat models, and to investigate the roles of PDTC in the process of intervertebral disc degeneration and the mechanism involved.Methods Fifty-four SD rats were divided into three groups randomly, then the dynamic equilibrium rat model was established by cutting the nuchal superficial and deep muscle of the rats.The dynamic equilibrium rats with PDTC solution intraperitoneal injection after operations were defined as PDTC group (group A), the models with saline intraperitoneal injection after operations as saline group (group B), the rats of fake operation with saline intraperitoneal injection as blank group (group C), and the animals were sacrificed in batches 10 weeks, 12 weeks, 16 weeks respectively after operation.The C5, C6 vertebrae and C5/6 discs were harvested, and the disc morphology was observed.TNF-α, MMP-9 mRNA expressions were detected by q-PCR and protein expression was observed by Western blot.Results Compared with the saline group, the morphology of disc in PDTC group was destructed slightly and fiber ring arranged orderly.TNF-α, MMP-9 gene and protein expressions had no obvious changes (P>0.05) in blank group (group C) at each time point.The expressions of IL-6, MMP-9 mRNA increased with time in group B, but the amount increased fast firstly, and slow lately, reaching peak in 12 weeks.The expression of TNF-α, MMP-9 protein became steady in group B from 10 weeks compared with other time points(P>0.05).TNF-α, MMP-9 genes and proteins expression decreased obviously in PDTC group (group A) compared with saline group (group B) (P<0.01) at each time point, but higher than blank group C(P<0.01) at each time point.Conclusions TNF-α and MMP-9 are important inflammatory factors involved in rat cervical disc degeneration, PDTC relieves the degeneration of rat cervical disc by reducing the expression of TNF-α and MMP-9 via disturbing the NF-κB signal pathway probably, and PDTC may become potential medicine for disc degeneration.

Objective The clinical manifestations of Parkinson''s disease (PD) are divided into non-motor symptoms and motor symptoms.Constipation is one of the common symptoms of non-motor symptoms of the disease.Constipation symptoms in PD generally occur earlier for 5~20 years, while drug treatment for PD constipation can lead to gastrointestinal damage.This study investigated the improvement in the treatment of anorectal dynamics and constipation symptoms in Parkinson''s disease by oral mosapride and press-needle therapy of Shu-Mu point.Methods 60 patients diagnosed as constipation of Parkinson''s disease were randomly divided into control group and treatment group, 30 cases in each group;patients in the control group were treated with oral mosapride tablets, while patients in the treatment group received press-needle therapy, three times per week.The observation course in both groups last for three months and follow-up visits were conducted before and after the course.Efficacy evaluation, PAC-QOL scale and anorectal dynamic examination were applied in the follow-up visit.Results The efficiency of treatment group was 81.7%, significantly higher than control group (70%), representing significant difference between the two groups (P<0.05).Both the methods could improve the PAC-QOL scale, and significant difference was found in comparison to that before the treatment(P<0.01), while no statistical significance was found between treatment group and control group after treatment(P>0.05).As to the anorectal dynamics, significant difference was found before and after the treatment in both groups (P<0.05, P<0.01), while no statistical significance were found between the two groups after treatment(P>0.05).Conclusion Both oral mosapride and press-needle can improve the quality of life and anorectal dynamics for PD patients, representing no significant difference.However, compared with mosapride, the overall efficacy of press-needle is better in improving the symptoms of constipation in PD, featuring more convenience, higher safety, less pain and no side effect, and it is worthy of clinical application.
