OBJECTIVE To establish an evaluation index system for the selection of therapeutic drugs for colorectal carcinoma， providing a basis for clinical medication decision-making. METHODS A preliminary framework for the evaluation index system for the selection of therapeutic drugs for colorectal carcinoma was constructed through literature research and expert surveys. Using the Delphi method， consultations were conducted with 40 experts engaged in the use and evaluation of antitumor drugs， ultimately forming the evaluation system for selecting therapeutic drugs for colorectal carcinoma. RESULTS The effective recovery rate of questionnaires for both rounds of inquiries was 100%， with the reliability coefficients of 0.82 and 0.85. The Kendall’s W coordination coefficients were 0.251 and 0.252 （the P values of χ 2 tests were both less than 0.05）. The final evaluation system constructed included 6 first-level indicators （safety， efficacy， cost-effectiveness， suitability， innovation， and accessibility） and 29 second-level indicators （such as disease control rate， precise treatment of target diseases， objective remission rate， and whether clinical medication complies with authoritative recommendations）. Among these， efficacy and accessibility received high average importance scores （4.60， 4.30 points）， with “disease control rate” and “precision treatment for target disease” carrying relatively high weights （both were 0.035 2）. CONCLUSIONS This study successfully established a drug evaluation index system for the selection of therapeutic drugs for colorectal cancer that aligns with clinical practice.

Turning to critical illness is a common stage of various diseases and injuries before death. Patients usually have complex health conditions, while the treatment process involves a wide range of content, along with high requirements for doctor′s professionalism and multi-specialty teamwork, as well as a great demand for time-sensitive treatments. However, this is not matched with critical care professionals and the current state of medical care in China. Telemedicine, which shortens the distance of medical professionals and the gap of disease diagnosis and treatments in various regions through electronic information, can effectively solve the current problem. Therefore, there is an urgent need to develop a standardized, high-quality visualization telemedicine round system .Therefore, experts have been organized to search domestic and foreign literature on telemedicine round for critically ill patients and to form this consensus based on clinical experiences so as to further improve the level of critical care treatments in regions.

Based on the results of the National Drug Sampling and Inspection Programme,we summarized the history,the standard collection,the production enterprises and the dosage form specifications,the quality standard study,the pharmacological and pharmacodynamic study,and the clinical application study of Wuwei Qingzhuo preparation of Mongolian medicine and Shiliu Jianwei preparation of Zang medicine,to provide the basis for improved quality standards for both preparations.The development of these two preparations was searched and analyzed through literature.The available information shows that there is very little research on the two preparations and insufficient pharmacological experimental and clinical experimental data.The two preparations are basically the same in prescription and efficacy.However,the quality standards are very different,which are not conducive to the quality control of the two and their related dosage forms.And it is suggested that the Chinese Pharmacopoeia should take the situation of this category into comprehensive consideration,and unify the quality standards of the two preparations.

Objective Reliability and validity of the Chinese version of disability attitude scales(DAS-CN)toward disabled persons were created and tested to provide an assessment instrument for measuring the attitude of medical staff toward disabled persons in China.Methods Authorised by the author of DAS in August 2020,based on BRISLIN translation model,the English version of DAS was translated into Chinese followed by back translation,cultural debugging and then put it into pre-experiment in September 2020.The reliability and validity of the finalised DAS-CN were further tested in a survey with 400 randomly selected medical staff in rehabilitation from 8 general hospitals in Jinzhou,Panjin,Yingkou and Fushun in Liaoning Province,China by using the convenience sampling method in March 2021.Results A total of 357 surveyees completed the survey.The localised DSA-CN was composed of 4 dimensions with a total of 20 items,including 4 items in clinical knowledge and skills,4 in clinical responsibility,8 in clinical behaviour and 4 in emotional response.The Cronbach α coefficient of the scales was 0.943,with the split-half reliability and test-retest reliability at 0.824 and 0.899,respectively.The Cronbach α coefficient of each dimension was 0.843～0.944,and the split half reliability was 0.854～0.904.The test-retest reliability ranged from 0.701 to 0.913.The KMO value of exploratory factor analysis was 0.921.The Bartrett spherical test value was 5534.981(P<0.01).The total explanatory rate of variation was 73.050%.Conclusion The Chinese version of Disability Attitude Scales(DSA-CN)has good reliability and validity.Therefore,DSA-CN can be used as an instrument in investigation of the current status about the attitudes towards the disabled persons among the medical staff in China.

To characterize human antibodies against low-calcium response V(LcrV)antigen of Yersinia pestis,the mono-clonal antibodies were screened and assayed.Antibody gene was derived from peripheral blood mononuclear cells of the vaccin-ees immunized by plague subunit vaccine in phase Ⅱb clinical trial.Human ScFv antibody library was constructed by phage dis-play.After panning library by using recombinant LcrV antigen,antibody variable genes were sequenced and converted into IgG1 format to evaluate its binding specificity and relevant parameters.An anti-plague human ScFv antibody library was estab-lished contained 7.54× 108 independent clones.After panning by LcrV antigen,3 human antibodies named as RV-B4,RV-D1 and RV-E8,respectively,were identified.Using indirect enzyme-linked immunosorbent assay(ELISA)and Western blot(WB),the specific bindings of the mAbs to LcrV antigen were confirmed.The dissociation constant(KD)of them to LcrV is 2.1 nmol/L,1.24 nmol/L and 42 nmol/L,respectively.Minor protective efficacy was found among 3 human antibodies in Y.pestis 141-infected mice.Three anti-LcrV monoclonal antibodies generated from immunized vaccinees were binding specific antibod-ies and could not block plague infection in mice.These antibodies are the potential candidate reagents for basic research of plague immunity and the application of plague diagnosis.

Objective To evaluate the diagnostic value of ischemia-modified albumin(IMA)and the crea-tine kinase(CK)index in acute ischemic stroke(AIS).Methods According to the inclusion and exclusion cri-teria,totally 149 newly diagnosed and untreated AIS patients hospitalized in Henan Provincial People's Hospi-tal from October 2021 to October 2022 were selected as the AIS group.Additionally,156 healthy people who underwent the physical examination during the same period were selected as the control group.Activity levels of IMA,CK,creatine kinase-MB(CK-MB),lactate dehydrogenase(LDH)and hydroxybutyrate-dehydrogen-ase(HBDH)were measured using the Abbott C1600 biochemical analyzer,and the CK index(ratio of CK-MB to CK)was calculated.Relative risk factors were analyzed,receiver operating characteristics(ROC)curve was constructed,data were analyzed using SPSS27.0.1,graphs were plotted using GraphPad Prism 9.4.1,and differences in area under the curve(AUC)were compared using MedCalc(version 20.0.22).Results The AIS group exhibited significantly higher levels of IMA,CK-MB,and the CK index,and significantly lower levels of CK compared to the control group(all P＜0.05).Univariate logistic regression analysis revealed that both IMA and the CK index were risk factors for AIS(both P＜0.001).After adjusting for gender and age in a multivariate binary logistic regression analysis,IMA emerged as an independent risk factor for AIS(OR=1.901,95％CI:1.649-2.190,P＜0.001).IMA,CK-MB and CK index in the AIS group were significantly higher than those in the control group,and CK levels were significantly lower than those in the control group,and the differences were statistically significant(P＜0.05).Univariate Logistic regression analysis showed that IMA and CK index were risk factors for AIS(P＜0.001).After adjusting for sex and age in multivariate binary Logistic regression analysis,IMA was an independent risk factor for AIS(OR=1.901,95％CI:1.649-2.190,P＜0.001).The ROC curve demonstrated that AUC,the sensitivity and the specificity of sin-gle detection for IMA were 0.922,81.2％,and 90.4％,respectively.There was no significant difference compared to combined detection using IMA+CK index or IMA+CK index+CK(all P＞0.05).Conclusion IMA is an independent risk factor for AIS,which has strong diagnostic value and is worthy of clinical application.
