Objective To estimate effects of Qingpeng ointment on skin barrier function,and to explore their potential mechanisms.Methods A total of 12 female volunteers with xerosis on the extensor surfaces of legs were enrolled into this study.All the volunteers were topically treated with Qingpeng ointment on the right leg (Qingpeng side) and its vehicle on the left leg (vehicle side) twice daily for 7 consecutive days.Skin barrier function-associated indexes including transepidermal water loss (TEWL) and the water content of the stratum corneum were measured before the treatment,after 3-and 7-day treatment separately.Thirty-six BALB/c female mice were randomly and equally divided into 6 groups:a blank control group receiving no induction or treatment,a model group induced by 2,4-dinitrofluorobenzene (DNFB) on the back for 5 consecutive weeks,3 Qingpeng groups and a vehicle group induced by DNFB on the back for 5 consecutive weeks followed by topical treatment with different concentrations (50％,75％,100％) of Qingpeng ointment or its vehicle twice a day for 2 consecutive weeks.At the end of treatment,skin appearance of mice was observed with naked eyes,skinfold thickness and TEWL were measured.Then,all the mice were sacrificed,and skin tissue specimens were resected from the back of mice followed by histopathologic examination and immunohistochemical staining for the detection of filaggrin (FLG),involucrin (IVL) and kallikrein 7 (KLK7) expressions in the epidermis.Results After start of treatment,both the Qingpeng side and vehicle side showed significantly decreased TEWL on day 3 (t =2.651,2.996,respectively,both P＜ 0.05) and 7 (t =3.615,3.586,respectively,both P＜ 0.05),but increased water content of the stratum corneum on day 3 (t=9.029,5.830,respectively,both P＜ 0.001) and 7 (t =13.842,11.299,respectively,both P ＜ 0.001) compared with those before the treatment.However,no significant differences were observed in TEWL or the water content of the stratum corneum between the Qingpeng side and vehicle side at any of the time points (all P ＞ 0.05).In addition,there were no marked differences in mouse skin appearance,skinfold thickness or histopathologic manifestations between the vehicle group and model group,while the manifestations of dermatitis were attenuated to different extents in the three Qingpeng groups compared with the model group.Both TEWL and KLK7 expression levels were significantly decreased in the vehicle group and three Qingpeng groups compared with the model group (all P ＜ 0.05),but similar between the vehicle and Qingpeng groups (all P ＞ 0.05).Conclusion The vehicle of Qingpeng ointment can improve skin barrier function.

Objective To prepare a novel bioactive and degradable scaffold with mineralized collagenpolyose based composite by biomimetic synthesis for bone tissue engineering and explore the compatibility of osteoblast culturing on the scaffold. Methods Two kinds of polyelectrolyte were assembled on the surface of diatomite particles in order to adsorbe on nano-zirconia through opposite charges. Zeta potential,particle size and size distribution were compared before and after the modification of diatomite; IR was used to analysis molecular structure of functional group changes on the surface of diatomite particles, nano-composite powder morphology was observed by SEM. Results Two kinds of the polyelectrolyte were successfully assembled on the surface of diatomite powders. Particle size and size distribution were significantly reduced, d (0.5) reduce from 16.421 μm to 0.420 μm. SEM showed the dispersion of the modified diatomite was improved and had a good adsorption with nano-zirconia. Conclusion Layer-by-layer technique could enhance the dispersion of diatomite-based dental ceramic powders as well as a good adsorption of nano-composite ceramic powder.

Objective:To identify the risk factors for postoperative delirium (POD) in frail elderly patients undergoing cardiac surgery and develop a ROC prediction model.Methods:The medical records of patients of either sex, aged ≥65 yr, of American Society of Anesthesiologists Physical Status classification Ⅲ or Ⅳ, with frailty index score>0.25, underwent open heart surgery under cardiopulmonary bypass (CPB) from January 2022 to June 2022, were collected retrospectively.The patients were divided into POD group and non-POD group according to POD occurred within 7 days after operation.Clinical information such as gender, age, Mini-mental State Examination score, past medical history, results of the laboratory test before surgery, operation time, cerebral oxygen saturation (rSO 2), rSO 2 baseline (rSO 2 baseline), lowest intraoperative rSO 2 value before, during and after CPB (CPB 1rSO 2 lowest, CPB 2rSO 2 lowest, CPB 3rSO 2 lowest) , the greatest decrease in intraoperative rSO 2 from the baseline value before, during and after CPB (CPB 1rSO 2 decrease, CPB 2rSO 2 decrease, CPB 3rSO 2 decrease) were recorded.Multivariate logistic regression analysis was used to identify the risk factors for POD, and the receiver operating characteristic (ROC) curve was drawn to evaluate the accuracy of the related risk factors. Results:A total of 130 patients were enrolled, with 32 cases in POD group and 98 cases in non-POD group, and the incidence of POD was 24.6%.The results of logistic regression analysis showed that the CPB 2rSO 2 decrease, CPB 2rSO 2 lowest and operation time were independent risk factors for POD ( P<0.05). The area under the ROC curve (95% confidence interval) of CPB 2rSO 2 decrease>11.2% predicting POD was 0.655 (0.533-0.778), sensitivity 68.9%, and specificity 62.9%.The area under the ROC curve (95% confidence interval) of operation time>237.5 min predicting POD was 0.751 (0.652-0.849), sensitivity 62.5%, and specificity 78.6%. Conclusions:CPB 2rSO 2 decrease, CPB 2rSO 2 lowest and operation time are independent risk factors for POD in frail elderly patients undergoing cardiac surgery; both CPB 2rSO 2 decrease and operation time can effectively predict the occurrence of POD in frail elderly patients undergoing cardiac surgery.

Early diagnosis is the key to improve the prognosis of gastric cancer. How to screen out high-risk subjects of gastric cancer in population is a hot spot. Serum-based early detection of gastric cancer is suitable for high-risk population screening, which is more convenient and safer. This article reviews the diagnostic value of serum biomarkers for gastric cancer, including serum DNA methylation, various RNAs, pepsinogen, gastrin, osteopontin, MG7-Ag and CA724. Until now, there is still lack of ideal biomarkers for gastric cancer, and searching for specific RNAs may be promising for early diagnosis and screening of gastric cancer.

OBJECTIVE： To systematically evaluate the mode of personnel training in pharmacy intravenous admixture services （PIVAS） in China， and to provide reference for the comprehensive training of pharmacist in PIVAS in China. METHODS： PubMed， Embase， Cochrane Library， CBM， CJFD， VIP and Wanfang database were searched from the establishment of database to Sept. 2018. Studies which evaluated the training mode of PIVAS in China were included， and the results were presented by descriptive analysis in respects of training objects， training objectives， contents and evaluation indicators. RESULTS： A total of 5 literatures were included. The research types were 2 before-after control studies， 2 experience sharing studies and 1 review. 3 subjects were pharmacists， 1 subject was clinical pharmacists， and 1 subject was nurses. The training objectives were comprehensive quality training， clinical rational drug use level， pharmacy personnel training path and professional service ability. The specific training content of the training mode varied greatly， including professional theoretical knowledge， practical operation ability， pre-job training， professional psychological quality， professional ethics and laws and regulations， continuing education learning ability， career development planning and teaching ability. There were great differences in the evaluation indicators of training effectiveness， which were mainly reflected in team execution motivation and creativity， discoveny rate of unreasonable doctor’s advice， work efficiency， service quality， drug treatment level and satisfaction of PIVAS， etc. CONCLUSIONS： There are certain differences in the training objectives， training targets， specific contents and evaluation indicators of the PIVAS pharmacist training model in China. It is necessary to use the evidence- based method to construct the training mode for PIVAS pharmacist to provide support for clinical intravenous drug use.

OBJECTIVE： To systematically evaluate current status of charges in pharmacy intravenous admixture services （PIVAS）， and to provide reference for the formulation of China’s pharmacy intravenous admixture services （PIVAS） charging standards. METHODS： Retrieved from PubMed， Embase， Cochrane library， CBM， CNKI， VIP， Wanfang database and related goverment websets， the literatures about current status evaluation of charges in PIVAS of China were collected during the establishment of database to Jan. 2019. Cost estimation， charge standard， influential factors and other indicators were collected， and the results were presented by descriptive analysis. RESULTS： A total of 5 literatures were included， all of which were reviewed. According to the existing literatures， except for Shandong， Guangdong and Yunnan provinces， there were no regional charge standards in other provinces （districts and cities）. The cost estimation methods of PIVAS in these three provinces were basically the same. The cost could be obtained by adding up the business fees， labor fees， fees of medical instruments purchase and use， indirect fees etc. Dispensing charges in PIVAS were 3-5 yuan per piece for general drug， 5 yuan per piece for antibiotics and 8-12 yuan per piece for cancer chemotherapeutics， 20-35 yuan per piece for TPN. The charging level was mainly affected by local prices， PIVAS scale， hardware investment， management and other factors. CONCLUSIONS： There is no unified charging standard for PIVAS in most provinces （districts， cities） of China. The cost estimation methods of the hospitals from the included literatures are basically the same. It is necessary to construct national PIVAS charging standard and cost estimation method， which could provide a basis for formulating the price of medical and health services.

OBJECTIVE： To systematically evaluate the status quo of cost estimation in pharmacy intravenous admixture services （PIVAS）， and to provide cost basis for the construction of PIVAS in China. METHODS： Retrieved from PubMed， Embase， Cochrane library， CBM， CNKI， CSJD and Wanfang database from database establishment to Jan. 2019， the studies about the status quo of cost estimation in PIVAS of China were included. The descriptive analysis was conducted for content and method of cost estimation， infection to hospital. RESULTS： A total of 17 literatures were included， involving 8 before and after control studies， 6 experience sharing studies and 3 reviews. Existing reports showed that the estimation contents and methods of PIVAS cost were roughly the same. The cost included manpower， medical and health materials， fixed asset purchase， depreciation， repair costs， medicine cost and indirect costs. At the same time， the infection to hospital were reported， such as in manpower adopting， formulating detailed management measures and systems， concurrent allocation of the same kind of drugs， shortening infusion preparation and replacement time， in order to save manpower cost. CONCLUSIONS： PIVAS cost calculation method is roughly the same in some hospitals， but there is no uniform standard. It is necessary to further improve the PIVAS cost measurement standard and provide a basis for the construction and development of PIVAS in China.
