Practice base of professional moral education of university is the important constituent of practice base of moral education of university. Practice base of professional moral education of university is a training place of undergraduate professional ideal、professional concept、professional attitude、professional discipline、professional style、professional value which be built by the nation、all levels of local government or university according as the moral education goal of university and the undergraduate body and mind law of development, specially the law of moral forms. The construction of practice base of professional moral education of university is a important action to enhance the actual effect of the professional moral education for medico. The construction of practice base of professional moral education of university ought to follow the policy of"being educated、enhancing ability、contributing" and the principle of "benefiting each other、adjust measures to local conditions and economy、understanding each other and integrating through free will". Finally the article discuss the pattern of the construction of practice base of professional moral education of university for medico and put forward three kind of patterns of the construction of practice base of professional moral education of universityaccording to the actual fact of the college.

Objective To summarize the experience in nursing locally preserved skin of female patients for neurosurgical cranioctomy. Method The nursing key points were given to 66 female patients undergoing local preparation of skin for cranioctomy as follous preoperative preparation, observation over incision and head nursing. Results The time for skin preparation ranged between 3 to 6 minutes. Postoperatively, no drain tube was placed. No intracranial infections occurred. The incisions in all patients were healed at the first class. Conclusion The nursing measures of good preoperative preparation, close observation of incisions and care to the head for female patients undergoing local preparation of skin for cranioctomy can enhance their satisfaction and propel development of standardized nursing.

On the basis of analysis and summary of current application of reference extracts of traditional Chinese medicine, reference extracts for quality assessment of traditional Chinese medicines are divided into three classes by purpose: 1. herbal or volatile oil reference extracts for TLC identification of original herbal medicines or patent traditional Chinese medicines containing original herbal medicines. 2. component reference extracts for identification of certain components or positioning of chromatographic peaks. 3. reference extracts marked with component content to be determined for quantitative analysis on samples. For the third kind of reference extracts, akebiae saponin was taken as an example for preparation thought and methods in such aspects as preparation process, component identification and content analysis.

BACKGROUND:At present,many drugs used in the treatment of polycystic ovary syndrome are super-designated drugs,and the treatment of patients with polycystic ovary syndrome still faces great challenges.Studies have shown that human umbilical cord mesenchymal stem cells can repair ovarian function,but few studies have reported their therapeutic effect on polycystic ovary syndrome. OBJECTIVE:To investigate the therapeutic effect of human umbilical cord mesenchymal stem cells on polycystic ovary syndrome,and to preliminarily explore the correlation between mitochondrial autophagy and the improvement of polycystic ovary syndrome by human umbilical cord mesenchymal stem cells. METHODS:Polycystic ovary syndrome mouse model was established by subcutaneous injection of dehydroepiandrosterone for 20 days into C57BL/6J mice.Human umbilical cord mesenchymal stem cells(2×106)were injected through the caudal vein.After treatment,vaginal secretions were collected for 10 consecutive days to detect the estrus cycle of mice.At 2 weeks after treatment,the levels of sex hormones in the peripheral blood of mice,including luteinizing hormone and follicle-stimulating hormone,were detected by ELISA.Hematoxylin-eosin staining was used to evaluate ovarian histopathology.Finally,mitochondrial autophagy in ovaries was observed by transmission electron microscopy. RESULTS AND CONCLUSION:(1)After human umbilical cord mesenchymal stem cell therapy,follicles at different stages(primitive follicles,primary follicles,and secondary follicles)appeared in the ovary of polycystic ovary syndrome mice,and luteal tissue could be seen,indicating that ovulation function of mice was effectively improved.(2)Polycystic ovary syndrome mice treated with human umbilical cord mesenchymal stem cells had sex hormone levels.(3)Untreated polycystic ovary syndrome mice were found to be in the estrous stage for a long time,lacking estrous interphase and estrous phase,but after human umbilical cord mesenchymal stem cell therapy,the estrous cycle returned to a normal level.(4)After treatment with human umbilical cord mesenchymal stem cells,the mitochondrial autophagy of polycystic ovary syndrome mice was significantly reduced.(5)The results show that human umbilical cord mesenchymal stem cells can effectively improve the symptoms of endocrine disorders and promote ovulation in polycystic ovary syndrome mice,which may be related to the inhibition of mitochondrial autophagy.

Objective:To explore the factors on malnutrition or risk of malnutrition in patients with Alzheimer′s disease (AD)-related cognitive impairment,and to further analyze the association between the severity of behavioral and psychological symptoms in dementia (BPSD) and nutritional status.Methods:The clinical data of 247 patients with AD-related cognitive impairment were collected continuously from the Chinese Imaging, Biomarkers and Lifestyle Study of Alzheimer′s Disease (CIBL) cohort between June 1, 2021 and August 31, 2022. The patients were divided into well-nourished group ( n=128) and malnourished group ( n=119) according to the scores of Mini-Nutritional Assessment scale (MNA). The sociodemographic data (sex, age, body mass index, waist-to-hip ratio, education level), the medical history of olfactory dysfunction, combination with more than two chronic diseases, and gastrointestinal diseases, presenting BPSD, and the scores of the Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA), Neuropsychiatric Inventory (NPI), Activity of Daily Living (ADL), Caregiver Burden Inventory (CBI) and Dietary Diversity Score (DDS) were compared between the two groups. The factors with statistically significant differences in hypothesis test and univariate Logistic regression analysis were enrolled in multivariate Logistic regression analysis to further identify independent factors associated with malnutrition in patients with AD-related cognitive impairment. Furthermore, the association between NPI scores and MNA scores was analyzed by Spearman′s rank correlation test. Results:Compared with those in the well-nourished group, patients in the malnourished group had higher age [(66.70±7.01) years vs (69.14±8.87) years, t=-2.39, P=0.018], lower body mass index [(24.68±2.84) kg/m 2vs (22.69±3.63) kg/m 2, t=4.78, P<0.001], and higher proportion of presenting BPSD [22.66% (29/128) vs 76.47% (91/119), χ 2=71.49, P<0.001]; lower scores of MMSE, MoCA, and DDS [24.27±4.69 vs 18.95±8.40, t=6.09; 20.29±5.18 vs 14.55±8.12, t=6.56; 8.00 (8.00, 9.00) vs 8.00 (7.00, 8.00), Z=-4.66; all P<0.001], and higher scores of NPI, ADL and CBI [1.00 (0, 6.00) vs 10.00 (2.00, 25.00), Z=-6.50; 20.00 (20.00, 22.00) vs 27.00 (20.00, 40.00), Z=-7.08; 1.00 (0, 14.75) vs 12.00 (2.00, 35.00), Z=-5.13; all P<0.001]. There were no statistically significant differences in the sex, waist-to-hip ratio, education level, and the medical history of olfactory dysfunction, combination with more than two chronic diseases, and gastrointestinal diseases between the two groups. The multiple Logistic regression analysis demonstrated that the decreased body mass index ( OR=0.79, 95% CI 0.70-0.89, P<0.001), presenting BPSD ( OR=7.84, 95% CI 3.67-16.73, P<0.001), elevated ADL scores ( OR=1.15, 95% CI 1.06-1.24, P<0.001) and CBI scores ( OR=0.98, 95% CI 0.97-1.00, P=0.026), and decreased scores of DDS ( OR=0.66, 95% CI 0.51-0.84, P=0.001) were independently associated with malnutrition in patients with AD-related cognitive impairment. The MNA scores were significantly negatively associated with NPI scores ( r=-0.483,95% CI -0.58--0.38, P<0.001). Conclusions:The decreased body mass index, dietary diversity, and ability of daily living, and presenting BPSD and heavy burden of caregivers can independently contribute to the malnutrition in patients with AD-related cognitive impairment. The more serious the BPSD, the worse the nutritional status.
