Objective:To develop a homogeneous management evaluation system for clinical observership teaching under the background of national first-class discipline construction.Methods:The preliminary contents of the assessment system were determined through a literature review and expert interviews, and two rounds of questionnaire-based consultation was conducted with 20 experts using the Delphi method. With the use of Excel 2016 and SPSS 26.0, we calculated the coefficient of judgement basis (Ca), the coefficient of familiarity (Cs), the coefficient of authority (Cr), and Kendall's coefficient of concordance ( W ) as well as the mean, standard deviation, and coefficient of variation of all parameters, to identify the specific items and weights for the homogeneous management evaluation system for clinical observership teaching under the background of national first-class discipline construction. Results:In the two rounds of consultation, experts were both 100.00% active in responding to the questionnaires; the coefficients of authority of experts were 0.889 and 0.935, respectively; the coefficients of familiarity were 0.856 and 0.936, respectively; the coefficients of judgment were 0.922 and 0.934, respectively; and Kendall's coefficients of concordance were 0.476 and 0.563, respectively. Finally, 7 first-level items and 21 second-level items were included in the content framework of the homogeneous management evaluation system.Conclusions:The construction process of the homogeneous management evaluation system of clinical observership teaching is complete and reliable, which can provide a reference for the homogeneous management of clinical observership teaching, but further verification and improvement are needed.

To investigate the clinical and pathological characteristics of duodenal-type follicular lymphoma (D-FL), and to deepen the understanding of Duodenal-type follicular lymphoma. The clinical symptoms, endoscopic features, pathologic features, immunophenotype, molecular pathological features and treatment follow-up of 18 D-FL patients diagnosed in Department of Pathology, Beijing Tiantan Hospital affiliated to Capital Medical University between January 2020 and July 2023 were summarized. A total of 18 patients with D-FL were included, including 10 males and 8 females. The median age was 49 (32-69) years respectively. Most of the patients were found during gastroenteroscopy or presented with the common gastrointestinal symptoms of stomach pain, acid reflux, vomiting and diarrhea. Most endoscopic findings were multiple small gray and white polyposis. In the pathological morphology, the mucous layer and submucous layer showed lymphoid follicular structures with full and strained follicles. The immunophenotype showed that the tumor cells strongly expressed CD20 and BCL2 and had low proliferation activity. Immunoglobulin clonal analysis of 1 case showed IgK monoclonal rearrangement (1/1). FISH showed 1 case of BCL2 gene rearrangement (1/3). All patients did not receive targeted chemotherapy and adopted a wait-and-see strategy. Median follow-up was 12 (2-34) months. This study shows that D-FL is an indolent lymphoma, which tends to occur in the duodenum and has a good prognosis.

Objective To explore the expression of serum bone morphogenetic protein 2(BMP2),bone morphogenetic protein 7(BMP7)level and its association with left ventricular hypertrophy(LVH)among patients with chronic kidney disease(CKD).Methods A total of 93 CKD patients admitted to Yan'an People's Hospital from June 2019 to June 2023 were collected as CKD group,divided into LVH group(n=34)and non-LVH group(n=59)according to whether concurrence was combined with LVH.A total of 60 healthy volunteers were selected as control group in the same period.The clinical data were collected and serum BMP2 and BMP7 levels were detected by enzyme-linked immunosorbent assay(ELISA).The association between serum BMP2,BMP7 and CKD stage was analyzed by Spearman's rank correlation analysis.Logistic regression analyze was performed to analyze the influencing factors of CKD patients with concomitant LVH.ROC curves were plotted to assess the diagnostic value of serum BMP2,BMP7 on LVH.Results Serum BMP2(106.09±19.34 pg/ml)in CKD group was higher than that in control group(83.76±15.27 pg/ml),and serum BMP7(15.16±4.92 pg/ml)in CKD group was lower than that in control group(26.53±5.80 pg/ml),the differences were statistically significant(t=7.559,13.002,all P<0.05).Serum BMP2 was sequentially increased in patients with CKD stages Ⅰ,Ⅱ,Ⅲ,Ⅳ and Ⅴ(90.32±6.04,98.56±6.63,110.32±7.49,121.13±7.82,131.81±7.97 pg/ml),and serum BMP7 was sequentially decreased (20.06±2.79,17.01±2.22,13.34±2.18,11.20±2.01,9.35±2.09 pg/ml),and the differences were statistically significant(F=19.863,11.567,all P<0.05).Serum BMP2 was positively correlated with CKD stage(r=0.592,P<0.05),while serum BMP7 was negatively correlated with CKD stage(r=-0.603,P<0.05).BMP2 was an independent risk factor for LVH in CKD patients[OR(95％CI):1.640(1.317～2.043),P<0.05].BMP7 was a protective factor for LVH in CKD patients[OR(95％CI):0.521(0.349～0.779),P<0.05].Both serum BMP2 and BMP7 had diagnostic value for LVH with AUC(95％CI)of 0.782(0.719～0.832)and 0.791(0.726～0.859),respectively.The AUC(95％CI)of the combination of two indicators was 0.873(0.812～0.930),which was greater than that of single indicator(Z=2.357,2.027,all P<0.05).Conclusion BMP2 is abnormally elevated and BMP7 is abnormally decreased in CKD patients,and the abnormal expression of two indicators is associated with CKD disease and LVH.Early combined detection of two indexes can be used as an indicator for diagnosing LVH.

【Objective】 To analyze the basic characteristics of whole blood donors from blood stations before and after the outbreak of COVID-19. 【Methods】 After excluding invalid data, data related to the basic characteristics of whole blood donors collected from 26 blood stations in China during 2018 to 2021 were statistically analyzed, including the trend of total whole blood donors, the number of repeated blood donors, the frequency of blood donation, the average age of donors and the recruitment of first-time blood donors. 【Results】 Affected by the epidemic, 8 out of 14 indicators were with large variations, accounting for 57%. The overall growth rate of total whole blood donors during the epidemic was higher than before the epidemic (P<0.05).The number of repeated blood donors has shown an increased trend, with a higher number during the epidemic than before (P<0.05). The frequency of blood donation was lower during the epidemic than before(P<0.05).Average ages of blood donors and female blood donors fluctuated widely during the epidemic, both higher than those before the epidemic(P<0.05).The donation rate of first-time blood donors <25 years old and ≥25 years old varied widely and irregularly during the epidemic (both P<0.05). The percentage of first-time blood donors fluctuated irregularly during the epidemic, with overall percentage lower than that before the epidemic(P<0.05). 【Conclusion】 Whole blood donors from 26 blood stations increased after the outbreak of COVID-19, and some indicators in certain areas showed significant fluctuations during the epidemic.

Objective To investigate the influencing factors for direct-acting antiviral agent (DAA) therapy failure in the treatment of hepatitis C by comparing baseline clinical data and resistance-associated substitution (RAS) in sequencing data between the patients with HCV RNA reactivation after DAA therapy and the patients with successful DAA treatment. Methods A total of 13 patients from multiple centers who failed DAA therapy from November 2019 to October 2021 were enrolled as treatment failure group, and sequencing was performed for their positive serum samples. A total of 51 patients with successful DAA treatment were enrolled as control group, and baseline clinical data and sequencing results were compared between the treatment failure group and the control group. The Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups, and the chi-square test was used for comparison of categorical data between groups; univariate and multivariate logistic regression analyses were performed to calculate odds ratio ( OR ) and investigate the influencing factors for treatment failure. Results All 12 patients with complete treatment data experienced recurrence within 1 year after the end of medication. The male patients with treatment failure had significantly higher baseline total bilirubin, direct bilirubin, and creatinine than their female counterparts ( Z =-2.517, -2.440, and -2.132, P =0.010, 0.010, and 0.038), and the patients with an age of ≤55 years ( OR =5.152, 95% confidence interval [ CI ]: 1.116-23.790, P =0.036) or genotype 3b ( OR =9.726, 95% CI : 1.325-71.398, P =0.025) had a higher probability of treatment failure. There were differences in the incidence rates of major RAS mutations on three gene fragments between the treatment failure group and the treatment success group, and the common RAS mutations detected in the treatment failure group were not detected in the treatment success group. Conclusion Age, genotype, and RAS in serum virus gene sequence are influencing factors for DAA treatment failure.

OBJECTIVE To excavate and evaluate β-blockers associated with acute renal failure（ARF）signal. METHODS Using the report odds ratio （ROR）method and Bayesian confidence interval progressive neural network （BCPNN）method，signal detection and analysis were performed for 4 kinds of β-blockers（metoprolol，bisoprolol，atenolol，nebivolol）associated with ARF Δ 基金项目：重庆市临床药学重点专科建设项目 （No.渝卫办发 in FDA adverse event reporting system （FAERS）from the two 〔2020〕68号）；重庆医科大学未来医学青年创新团队发展支持计划项 dimensions of Standard International Dictionary of Medical 目（No.W0081） Terms （MedDRA） analysis query （SMQ） term set and ＊药师，硕士研究生。研究方向：药物警戒。电话：023-68485161。 preferred term （PT） level terms.

RESULTS Totally 14 328 戒。电话：023-63625666。E-mail：jiayuntaomail@hospital.cqmu.edu.cn ARF reports of 4 kinds of β-blockers were retrieved within the ·1380· China Pharmacy 2022Vol. 33 No. 11 中国药房 2022年第33卷第11期 narrow sense of “acute renal failure ”in SMQ term set ，of which men （6 964）were more than women （6 206）. The age of patients was mainly concentrated in the middle-aged and elderly （≥45 years old ），and serious adverse events accounted for 77.23％. The results of signal retrieval based on SMQ term set showed that ROR values and 95％ confidence intervals of metoprolol ，bisoprolol， atenolol and nebivolol detected by ROR method were 2.58（2.51，2.65），5.30（5.14，5.47），2.80（2.69，2.91）and 3.28（3.04， 3.53）respectively. The signal components （IC）detected by BCPNN method and the lower limit of IC were 1.29（1.25），2.26 （2.22），1.42（1.36）and 1.64（1.53）respectively，suggesting suspicious signals were detected in these four kinds of β-blockers associated ARF. The results of signal detection based on PT level terms showed that 37 positive signals were detected by ROR method，38 positive signals were detected by BCPNN method ，and 36 suspicious signals were detected by the two methods at the same time. For each drug ，12 suspicious signals of metoprolol were detected at the same time ，9 suspicious signals of bisoprolol and atenolol were detected at the same time ，and 6 suspicious signals of nebivolol were detected at the same time ；the number and type of signals were different among the 4 kinds of drug. CONCLUSIONS Four kinds of β-blockers may cause ARF. Compared with metoprolol and atenolol ，bisoprolol and nebivolol have strong statistical correlation with ARF ，suggesting that medical personnel should pay attention to the possible renal related adverse reactions of these drugs in the process of clinical use.

Cachexia is a common complication in patients with lung cancer. It aggravates the toxic and side effects of chemotherapy, hinders the treatment plan, weakens the responsiveness of chemotherapy, reduces the quality of life, increases complications and mortality, and seriously endangers the physical and mental health of patients with lung cancer. The causes and pathogenesis of tumor cachexia are extremely complex, which makes its treatment difficult and complex. Controlling cachexia in lung cancer patients requires many means such as anti-tumor therapy, inhibition of inflammatory response, nutritional support, physical exercise, and relief of symptoms to exert the synergistic effect of multimodal therapy against multiple mechanisms of tumor cachexia. To date, there has been a consensus within the discipline that no single therapy can control the development of cachexia. Some therapies have made some progress, but they need to be implemented in combination with multimodal therapy after fully assessing the individual characteristics of lung cancer patients. This article reviews the application of drug therapy and nutritional support in lung cancer patients, and looks forward to the research direction of cachexia control in lung cancer patients.

OBJECTIVE To detect and evaluate the signals of amlodipine and lercanidipine -induced adverse drug events （ADE）. METHODS All ADE reports about “amlodipine”and“lercanidipine”were searched from FAERS database during Jan . 1st，2004 to Sept . 30th，2021. Reported odds ratio and Bayesian confidence propagation neural network were used to detect ADE signals. The moderately strong signals and strong signals in key systems were selected for analysis . RESULTS From FAERS database，249 657 and 10 558 reports were extracted with amlodipine and lercanidipine as suspect drugs ，respectively. In this study，62 and 58 signals related to amlodipine and lercanidipine were detected respectively . At the same time ，moderately strong signals of peripheral edema ， hypotension， orthostatic hypotension and hypovolemic shock were detected in the twodrugs，all of which were common adverse reactions of the two drugs. The special ADEs detected in this study were as follows： in the respiratory system ， chest and mediastinaldisease system ，strong signals of non -cardiogenic pulmonary edema were detected for amlodipine ，and strong signals of dyspnea at rest for lercanidipine ；in gastrointestinal diseases ，strong signals of gingival hypertrophy were detected only for amlodipine；in skin and subcutaneous tissue disease system ，moderately strong signals related to “vasculitis”were detected for both drugs，moderately strong signals related to linear IgA disease were detected for amlodipine ，and moderately strong signals related to bullous dermatitis were detected for lercanidipine ；in the renal and urinary system disease system ，the signals of acute renal injury were detected for both drugs （amlodipine was detected as a moderately strong signal ，and lecardipine was detected as a strong signal ）； in the mental system ，moderately strong signals related to suicide were detected for amlodipine . Both hypotension and acute renal injury ranked in the top two in the number of reports of the two drugs . The time scan results of the information component （IC）of this study showed that the IC values of non -cardiogenic pulmonary edema and suicide completion signals of amlodipine increased from 0.76，－0.49 to 4.48 and 1.95 respectively，and the confidence intervals narrowed from （－0.44，1.97），（－1.01，0.03）to （4.24，4.72）and（1.90，2.01）respectively during 2004 to 2021，suggesting that the signals kept stable . CONCLUSIONS The risks of peripheral edema ，hypotension，arrhythmia，pulmonary edema ，gingival hyperplasia ，skin related ADE ，acute renal injury ， depression and suicide should be alert when using amlodipine and lercanidipine in clinic .

OBJECTIVE： To mine and evaluate the post-marketing safety alert signals of pegaspargase （PEG-ASP） and L-asparaginase （L-ASP），and compare the safety differences between them ，so as to provide reference for clinical safe and rational drug use. METHODS ： The adverse drug event （ADE） reports of PEG-ASP and L-ASP issued by FDA adverse event reporting system from Jan. 1st，2004-Jun. 30th，2020 were retrieved. BCPNN method was used to mine the safety signals of these two drugs under the condition that the lower limit of information component （IC－2SD）＞0 and the number of events ≥3. The medium and strong signals of two drugs with IC －2SD≥1.5 were evaluated and compared in 8 system organ class，such as gastrointestinal system ，hepatobiliary system ，blood and lymphatic system ，blood vessels and lymphatic vessels ， nervous system ，immune system ，metabolism and nutrition ，various examinations. IC value of specific ADE signal and its 95％ confidence interval were analyzed by time scanning spectrum. RESULTS & CONCLUSIONS ：The reports of PEG-ASP and L-ASP as suspected drugs were 2 324 and 3 824；67 and 68 medium and strong signals were included ，respectively. In gastrointestinal system，the common strong signal of PEG-ASP and L-ASP was necrotic pancreatitis. In hepatobiliary system ，both of them showed strong signal in venoocclusive liver disease ，and this ADE was not included in the drug instruction. In blood and lymphatic system ， common strong signals of the two drugs were febrile neutropenia ，coagulation disorder ，neutropenia and febrile bone marrow regeneration disorder ；in blood vessels and lymphatic vessels ，in addition to haemodynamic instability ，IC values of other signals of L-ASP were higher than those of PEG-ASP. In nervous system ，IC values of other signals of L-ASP were higher than those of PEG-ASP except for intracranial haemorrhage. In immune system ，anaphylactic reaction was a medium signal for L-ASP but was a strong signal for PEG-ASP. In metabolism and nutritional diseases ，except for tumor lysis syndrome ，IC values of other signals of L-ASP were higher than those of PEG-ASP. The results of time scanning spectrum showed that the signals of necrotic pancreatitis and coagulation disorder of PEG-ASP were stable ，while the signals of veno occlusive liver disease and hypersensitivity were unstable and needed to be observed ；above four signals of L-ASP were stable signals. When using PEG-ASP or L-ASP clinically ， close attention should be paid to the safety problems such as hypersensitivity ，coagulation disorder ，thrombosis，necrotic pancreatitis，venoocclusive liver disease and hypoproteinemia.
