A rapid and sensitive liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/MS) method for quantification of sitagliptin in human plasma and urine had been developed. This method was applied to the pharmacokinetics study of sitagliptin tablet after single- and multiple-dosing in Chinese population. Plasma samples were prepared by a liquid-liquid extracted method, and urine samples were diluted. Compounds were analyzed by multiple reaction monitoring (MRM) mode with a electrospray ionization (ESI) interface. Mobile phase consisted of methanol and water (85 : 15, v/v). The linear concentration range of calibration curve was 0.5-1 000 ng.mL-1. and 0.2-100 µg.mL , intra-run/between-run accuracy was 98.98%-103.69% and 97.63%-102.29%, intra-run/between-run precision was <5.51% and 4.26% for plasma and urine sample, respectively. The stability of sitagliptin stock solution was tested for 55 days at -30 °C. Sitagliptin was stable when stored under the following conditions: 24 hours in the autosampler after sample preparation; 24 hours at room temperature, after 3 freeze and thaw cycles (from -30 °C to room temperature), 40 days at -30 °C for plasma and urine samples. The absolute recovery in plasma was 71.1%, and no matrix effect was founded. This method was proved simple, specific, sensitive, rapid and suitable for pharmacokinetics study of sitagliptin in human being.

The growing demand for new therapeutic strategies in the medical and pharmaceutic fields has resulted in a pressing need for novel druggable targets. Paradoxically, however, the targets of certain drugs that are already widely used in clinical practice have largely not been annotated. Because the pharmacologic effects of a drug can only be appreciated when its interactions with cellular components are clearly delineated, an integrated deconvolution of drug-target interactions for each drug is necessary. The emerging field of chemical proteomics represents a powerful mass spectrometry (MS)-based affinity chromatography approach for identifying proteome-wide small molecule-protein interactions and mapping these interactions to signaling and metabolic pathways. This technique could comprehensively characterize drug targets, profile the toxicity of known drugs, and identify possible off-target activities. With the use of this technique, candidate drug molecules could be optimized, and predictable side effects might consequently be avoided. Herein, we provide a holistic overview of the major chemical proteomic approaches and highlight recent advances in this area as well as its potential applications in drug discovery.

Objective:To investigate the potential mechanism by which Brucella suis vaccine strain S2 induces the apoptosis of BV-2 microglia cells, and to discover new protein targets for neurobrucellosis treatment. Methods:BV-2 microglia cells were treated with Brucella suis vaccine strain S2 for 0, 3, 6, 12 and 24 h. Western blot assay and RT-qPCR were performed to detect the expression of p-JNK and p53 at protein and mRNA levels in BV-2 microglia cells. Cell apoptosis was measured by flow cytometry. Immunofluorescence was used to analyze nuclear p-JNK. Results:Brucella suis vaccine strain S2 could promote the expression of p-JNK and p53 at both protein and mRNA levels and increase nuclear p-JNK in BV-2 microglia cells. Moreover, it could also induce the apoptosis of BV-2 microglia cells. Conclusions:Brucella suis vaccine strain S2 could promote the apoptosis of BV-2 microglia cells through activating JNK and promoting p53 expression.

By comparing the proportion of hospital pharmaceutical functions and work contents of different levels of pharmaceutical professionals at home and abroad, the authors divided pharmaceutical care in medical institutions into basic pharmaceutical care based on drug management and advanced pharmaceutical care based on drug treatment. Different pharmaceutical service levels created different pharmaceutical service values. Pharmaceutical classification service can stimulate the work potential of pharmaceutical professionals at all levels, improve the service level of pharmacists, and provide basis for the better distribution of medical costs in China.

Objective:To compare the clinical, pathological features and prognosis of patients who underwent pancreaticoduodenectomy with standard or extended lymph node dissection for pancreatic ductal adenocarcinoma.Methods:A retrospective study was performed on 158 pancreatic head cancer patients who underwent radical resection at the First Affiliated Hospital of Nanjing Medical University from Jul 2017 to Feb 2019. The clinicopathological characteristics and prognosis between the standard dissection group and the extended dissection group were compared. The relationship between the number of examined lymph nodes, positive lymph nodes, and the lymph node ratio, together with their relationship with survival were analyzed.Results:Survival analysis showed no statistical difference in survival between the standard resection group and the extended resection group ( P=0.99). There were statistical differences in gender and age composition between the two group, but no significant differences in operation time, blood loss, or postoperative complications were found. Patients with less examined lymph nodes tended to be of stage N0. examined lymph nodes is positively correlated with positive lymph nodes but is not significantly correlated with lymph node ratio. Positive lymph nodes is strongly correlated with lymph node ratio. The location of lymph node metastasis was not survival-related. Conclusions:There is no prognostic difference between standard lymph node dissection and extended lymph node dissection in pancreatic cancinoma patients after Whipple procedure.

Risk-adjusted capitation is a payment method that measures capitation rates based on patient′s characteristics such as age, gender, and clinical diseases. The cost standard calculation model is the basis for its application. This paper focused on risk-adjusted capitation, introduced the methodology of risk-adjusted model construction(including identifying the model type, variables, statistical models, and evaluation indicators) and applied an example of the model to measure risk-adjusted capitation payment standard. It is recommended that the academic community should promote the methodology research of risk adjustment model construction. Provinces and cities met the conditions should actively explore the risk adjustment capitation payment in practice, explore and deepen medical insurance payment reform, especially in outpatient services. When applying risk-adjusted capitation, supporting measures such as establishing and continuously improving basic database construction, model updating mechanisms, and adjusting special capitation payment standards should be established.

Objective:To investigate the relationship between clinicopathologic features and prognosis of pancreatic ductal adenocarcinoma located in the head of pancreas.Methods:A retrospective study was performed on 169 patients undergoing radical resection for pancreatic head cancer collected in the First Affiliated Hospital with Nanjing Medical University from January 2018 to April 2019. Univariate analysis and multivariate analysis were performed.Results:Patient′s age, tumor differentiation, tumor maximum diameter, resection margin (several resection margins including portal vein groove resection margin, posterior resection margin, and uncinate resection margin), number of positive lymph nodes, number of regional lymph node dissected, and some preoperative and postoperative indicators were associated with prognosis ( P<0.05). Direct tumor invasion of organs and surrounding tissues, perineural and vascular invasion, pathologic variants etc. had no statistical significance for survival time. Patient′s age, maximum tumor diameter, degree of differentiation, uncinate incision margin, number of regional lymph nodes dissected, and preoperative CA19-9 were independent factors affecting prognosis. Patients older than 74 years of age, with tumors larger than 3 cm in diameter, poorly differentiated, less than 7 regional lymph node dissected, positive uncinate margin, and preoperative CA19-9 higher than 1.5×10 5 U/L were independent risk factors in patients with pancreatic head cancer. Conclusions:Old age, tumor lager than 3 cm, poor differentiation, low examined lymph nodes, direct uncinate margin involvement and (or) with preoperative CA19-9 higher than 1.5×10 5 U/L are related to poor prognosis of head pancreatic cancer.

Objective To evaluate the status of home medication safety among elderly patients with chronic diseases and analyze its influencing factors in urban and rural areas of Henan Province.Methods Convenient sampling method was adopted.Data was collected through a designed and optimized questionnaire.Pharmacists conducted in-home surveys.Excel and SPSS 26.0 software were used for data analysis.Results A total of 352 valid questionnaires were analyzed.Most respondents were aged 60～70 years,with a female proportion of 56.2%,and 52.0%of them had a junior high school education or lower.The top-ranked chronic diseases were hypertension(62.2%)and hyperlipidemia(33.2%),and 61.1%of patients suffered from multiple chronic diseases.Antipyretic and analgesic drugs were most common in home medicine cabinets(90.1%).The proportion of drugs being stored in accordance with the instructions(46.9%)was slightly low,and 93.8%of the elderly handled expired drugs improperly.Awareness of medication guidance services was low(34.9%).Logistic regression analysis showed that factors such as education level and monthly income had significant effects on the understanding of drug package insert,rational drug storage,proper disposal of expired drugs,and awareness of medication guidance services(P<0.05).Conclusion There are still some potential safety risks in the home medication use of elderly patients with chronic diseases in urban and rural areas of Henan Province.It is necessary to enhance education on drug storage and medication guidance,particularly for low-income and less-educated groups,to improve the safety of home medication use.

Objective:To understand the evaluation of 90 pharmaceutical service posts by pharmacists in hospitals, so as to provide basis for rational allocation of pharmaceutical personnel in hospitals.Methods:A questionnaire survey was conducted among 2 582 hospital pharmacists in 31 provinces from August 2019 to April 2020. The survey contents included post classification, staffing qualification and scores related to drug safety.Results:Among the 90 pharmaceutical posts investigated, there were 39 posts with a safety correlation score of 5(the highest score), 36 with 4 and 15 with 3. There were 41 posts in advanced pharmaceutical care and 49 posts in basic pharmaceutical care. The minimum qualifications required was 21 posts with pharmacy related college degree or assistant pharmacist, 61 posts with pharmacy related or clinical pharmacy bachelor degree or pharmacist title, and 8 posts with higher qualification. Advanced pharmaceutical care posts had high drug safety relevance scores and high personnel qualification requirements, mainly involving drug treatment, scientific research and comprehensive management posts.Conclusions:Pharmacists with different qualifications should be allocated according to different levels of pharmaceutical care projects, which can reasonably allocate limited human resources and make the best of their talents.
