Objective: To construct a scientific and perfect evaluation index system of infectious disease prevention and control ability in colleges and universities, so as to provide reference tools for colleges and universities to effectively respond to infectious disease. Methods: The initial framework of the evaluation index system of infectious disease prevention and control ability in colleges and universities was constructed by using literature analysis method. Experts familiar with infectious disease prevention and control or school health work were selected to conduct two rounds( n =16，18) of Delphi expert consultation for determining the evaluation index system. Analytical hierarchy process was used to calculate the index weights and combined weights. About 198 prevention and control personnel were conveniently selected from 3 universities in Inner Mongolia Autonomous Region to comprehensively evaluate the evaluation indicators by using fuzzy comprehensive evaluation method. Results: After two rounds of Delphi consultation questionnaire, the effective recovery rates were 80.0% and 90.0%, the expert authority levels were 0.89 and 0.86, the expert harmony coefficients for Kendall W were 0.166 and 0.310, and the variation coefficient of each index was <0.25. Finally, the evaluation index system of infectious disease prevention and control ability of colleges and universities included 4 first level indicators, 14 second level indicators and 75 third level indicators. The weights of prevention and monitoring and early warning, organizational system guarantee, emergency management, rehabilitation and summary were 0.176, 0.476, 0.268 and 0.080, respectively. The top 3 weights of the secondary indexes were 0.623 for infectious disease surveillance and early warning, 0.595 for loss assessment and 0.370 for emergency response. The score of fuzzy comprehensive evaluation of the index system of infectious disease prevention and control ability in colleges and universities was 79.148, suggesting a high level. Conclusion The established evaluation index system of infectious disease prevention and control ability in colleges and universities is scientific and reasonable, which is conducive to provide tool reference for the evaluation of infectious disease prevention and control ability in colleges and universities.

OBJECTIVE: Based on metabonomics technology of high-performance liquid chromatography-mass spectrometry (HPLC-MS/MS) and hydrogen nuclear magnetic resonance spectroscopy (¹H NMR), the pharmacokinetic characteristics and therapeutic mechanism of Rhei Radix et Rhizoma (RhRR, Dahuang in Chinese), Eupolyphaga Steleophaga (EuS, Tubiechong in Chinese) combined with RhRR acting on acute liver injury were explored. METHODS: Models of acute liver injury were established, and the pharmacokinetic methods of five components of RhRR-EuS in rats were found by HPLC-MS/MS. The liver tissues of different groups of mice were analyzed by ¹H NMR spectroscopy combined with multivariate statistical analysis to investigate the metabolomics of RhRR-EuS and RhRR. RESULTS: Pharmacokinetic results showed there were different levels of bimodal phenomenon in different groups, and the absorption of free anthraquinone in RhRR increased after compatibility with EuS. In addition, the pathological state of acute liver injury in rats can selectively promote the absorption of emodin, chrysophanol, physcion and aloe emodin. Through 15 differential metabolites in the liver tissue of acute liver injury mice, it was revealed that RhRR-EuS and RhRR could protect the liver injury by regulating the metabolism of glutamine and glutamic acid, alanine, aspartic acid and glutamic acid, and phosphoinositide. However, the regulation of RhRR was weaker than that of RhRR-EuS. CONCLUSION For the first time, we studied the pharmacokinetics and metabolomics differences of RhRR-EuS and RhRR in rats and mice with acute liver injury, in order to provide theoretical reference for clinical treatment of liver disease by DHZCP.

ObjectiveBased on the nuclear factor erythroid 2 related factor 2 （Nrf2）/heme oxygenase-1 （HO-1） signaling pathway， this paper explores the effect of Sinisan （SNS） on liver oxidative stress injury in cholestatic hepatitis rats and its mechanism. MethodThirty 6-week-old male SD rats were randomly divided into a control group， model group， low and high dose groups of SNS （2.5 and 5 g·kg^-1） and ursodeoxycholic acid group （UDCA， 63 mg·kg^-1）， with six rats in each group. Rats were administrated for seven consecutive days. On the 5th day， the control group was given olive oil of 10 mL·kg^-1， and the other groups were given alpha-naphthalene isothiocyanate （ANIT） of 80 mg·kg^-1. The serum biochemical indicator levels of cholestasis and the content of antioxidant factors in rat liver were detected by enzyme-linked immunosorbent assay （ELISA）. Hematoxylin-eosin （HE） staining was used to observe the pathological changes in liver tissue. The relative mRNA and protein expressions of Nrf2， HO-1， and quinone oxidoreductase 1 （NQO1） in liver tissue were detected by real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） and Western blot. ResultCompared with the control group， the model group showed a significant increase in the serum biochemical indicator levels of cholestasis and the content of antioxidant factors in liver tissue （P<0.01）. There were obvious pathological changes in the model group such as the disordered arrangement of hepatocytes， obvious congestion and necrosis in the portal area， infiltration of inflammatory cells， and destruction of the interlobular bile duct. The relative mRNA and protein expressions of Nrf2， HO-1， and NQO1 in liver tissue were significantly down-regulated in the model group （P<0.05， P<0.01）. Compared with the model group， the groups of SNS showed a significant decrease in the serum biochemical indicator levels of cholestasis and the content of antioxidant factors in liver tissue （P<0.01）， and the pathological liver injury was obviously improved. The necrotic area was reduced， and the infiltration of inflammatory cells was decreased. In addition， there was a small amount of extravasated blood in the interlobular vein. The relative mRNA and protein expressions of Nrf2， HO-1， and NQO1 in liver tissue were significantly up-regulated （P<0.05， P<0.01）. ConclusionSNS can significantly improve liver injury in cholestatic hepatitis rats， and its mechanism may be related to the inhibition of oxidative stress response mediated by the Nrf2/HO-1 signaling pathway.

Afferent baroreflex failure(ABF)is a rare disease.It refers to the clinical syndrome caused by the impairment of the afferent limb of the baroreflex or its central connections at the level of the medul-la.The recognized causes include trauma,surgery in related areas(radical neck tumor surgery,carotid endarterectomy),neck radiotherapy,brain stem stroke,tumor growth paraganglioma and hereditary diseases,among which the most common cause is extensive neck surgery or radiotherapy for neck cancer.The main manifestations are fluctuating hypertension,orthostatic hypotension,paroxysmal tachycardia and bradycardia.This case is a young man,whose main feature is blood pressure fluctuation,accom-panied by neurogenic orthostatic hypotension(nOH).After examination,the common causes of hyper-tension and nOH were ruled out.Combined with the previous neck radiotherapy and neck lymph node dissection,it was considered that the blood pressure regulation was abnormal due to the damage of carotid sinus baroreceptor after radiotherapy for nasopharyngeal carcinoma and neck lymph node dissection,which was called ABF.At the same time,the patient was complicated with chronic hyponatremia.Com-bined with clinical and laboratory examination,the final consideration was caused by syndrome of in-appropriate antidiuretic hormone(SIADH).Baroreceptors controlled the secretion of heart rate,blood pres-sure and antidiuretic hormone through the mandatory"inhibition"signal.We speculate that the carotid sinus baroreceptor was damaged after neck radiotherapy and surgery,which leads to abnormal blood pres-sure regulation and nOH,while the function of inhibiting ADH secretion was weakened,resulting in higher ADH than normal level and mild hyponatremia.The goal of treating ABF patients was to reduce the frequency and amplitude of sudden changes in blood pressure and heart rate,and to alleviate the on-set of symptomatic hypotension.At present,drug treatment is still controversial,and non-drug treatment may alleviate some patients'symptoms,but long-term effective treatment still needs further study.The incidence of ABF is not high,but it may lead to serious cardiovascular and cerebrovascular events,and the mechanism involved is extremely complicated,and there are few related studies.The reports of rele-vant medical records warn that patients undergoing neck radiotherapy or surgery should minimize the da-mage to the baroreceptor in the carotid sinus in order to reduce the adverse prognosis caused by complica-tions.

By consulting ancient and modern literature， the herbal textual research of Farfarae Flos has been conducted to verify the name， origin， producing area， quality evaluation， harvesting and processing methods， so as to provide reference for the development and utilization of the famous classical formulas containing Farfarae Flos. According to the research， the results showed that Farfarae Flos was first described as a medicinal material by the name of Kuandonghua in Shennong Bencaojing（《神农本草经》）， and the name was used and justified by later generations. The main origin was the folwer buds of Tussilago farfara， in addition， the flower buds of Petasites japonicus were used as medicine in ancient times. The ancient harvesting time of Farfarae Flos was mostly in the twelfth month of the lunar calendar， and the modern harvesting time is in December or before the ground freeze when the flower buds have not been excavated. Hebei， Gansu， Shaanxi are the authentic producing areas with the good quality products. Since modern times， its quality is summarized as big， fat， purple-red color， no pedicel is better. Processing method from soaking with licorice water in the Northern and Southern dynasties to stir-frying with honey water followed by micro-fire in the Ming dynasty， and gradually evolved to the modern mainstream processing method of honey processing. Based on the research results， it is suggested that the dried flower buds of T. farfara， a Compositae plant， should be selected for the development of famous classical formulas containing Farfarae Flos， and the corresponding processed products should be selected according to the specific processing requirements of the formulas， and raw products are recommended for medicinal use without indicating processing requirements.

The assessment of adverse drug events is an important basis for clinical safety evaluation and post-marketing risk control of drugs,and its causality assessment is gaining increasing attention.The existing methods for assessing the causal relationship between drugs and the occurrence of adverse reactions can be broadly classified into three categories:global introspective methods,standardized methods,and probabilistic methods.At present,there is no systematic introduction of the operational details of the various methods in the domestic literature.This paper compares representative causality assessment methods in terms of definition and concept,methodological steps,industry evaluation and advantages and disadvantages,clarifies the basic process of determining the causality of adverse drug reactions,and discusses how to further improve the adverse drug reaction monitoring and evaluation system,with a view to providing a reference for drug development and pharmacovigilance work in China.

Objective To investigate the effects of adenosine triphosphate-binding cassette,sub-family C,member 2(ABCC2)rs717620 G＞A polymorphisms on serum concentrations and chemotherapy toxicities of methotrexate(MTX)in children with acute lymphoblastic leukemia(ALL).Methods Peripheral blood samples were obtained from children with ALL to extract genome DNA.Matrix-assisted laser desorption/ionization time of flight mass spectrometry was used to detect the genotypes of ABCC2 rs717620 G＞A polymorphisms.Fluorescence polarization immunoassay was employed to determine the serum concentrations of MTX.The incidences of ALL relapse and toxicities were recorded after chemotherapy with MTX.The associations of ABCC2 rs717620 G＞A polymorphisms with dose-adjusted serum concentrations(C/D ratios),relapse,and chemotherapy toxicities of MTX were analyzed.Results A total of 127 children were included in the present study.The frequencies of rs717620 GG,GA and AA genotypes were 82.68％,16.54％and 0.78％,respectively.The frequencies of G and A alleles were 90.94％and 9.06％,respectively.Children with the GG genotype had lower median C/D ratios of MTX in 24 h(11.94 μmol·L-1 per g·m-2),higher C/D ratios of MTX in 42 h(0.08 μmol·L-1 per g·m-2),and lower relapse rates(11.42％)than those in GA and AA genotype carriers(12.64 and 0.07 μmol·L-1 per g·m-2,and 18.18％,respectively).However,none of the above differences were statistically significant.The incidences of hematological(40.95％)and electrolyte disorders(21.90％)in children with the GG genotype were significantly higher than those in GA and AA genotype carriers(13.64％and 0.00％,respectively,P＜0.05).There were no statistically significant differences in the incidences of other adverse events between patients with the GG genotype and patients with the GA and AA genotypes(all P＞0.05).Conclusion ABCC2 rs717620 GG might be a risk factor for hematological and electrolyte disorders in ALL children treated with MTX.
