[Objective]To investigate the difference of ultrasound characteristics between pure mucinous carcinoma(PMC)and fibroadenoma(FA)of the breast.[Methods]Ultrasound data of 50 continuous patients with breast PMC from January 2012 to January 2021 and 100 continuous patients with breast FA from June 2018 to January 2019 in Sun Yat-sen Memorial Hospital of Sun Yat-sen University were retrospectively reviewed.The ultrasound characteristics of the two groups were evaluated according to the 2013 BI-RADS Ultrasound Atlas,and the differences in age,maximum diameter and ultrasound characteristics between the two groups were compared.[Results]The median age of PMC patients was 47 years and that of FA patients was 33 years.The age of PMC patients was higher than that of the FA group,and the differ-ence between the two groups of patients was statistically significant(P<0.001).The median maximum diameter of PMC pa-tients was 2.4 cm,which was greater than that of the FA group(1.8 cm),and the difference was statistically significant(P=0.001).Of the PMC,70%(35/50)were irregular,82%(41/50)were parallel to the skin,92%(46/50)had no circum-scribed margin,72%(36/50)were hypoechoic,and 68%(34/50)had enhanced posterior echo.Of the FA,69%(69/100)were oval or round,98%(98/100)were parallel to the skin,54%(54/100)had circumscribed margin,98%(98/100)were hypoechoic,and 75%(75/100)had no posterior features.The differences in the above ultrasound characteris-tics between the PMC and FA groups were statistically significant(P<0.001,P=0.001,P<0.001,P<0.001,P<0.001).There was no significant difference between calcifications and blood flow.[Conclusions]Compared with the FA group,pa-tients with PMC are older and the diameter of the lesions are larger.On ultrasound,the morphology and margin of most breast PMC still show the growth characteristics of invasive cancer.Meanwhile,the posterior echo of PMC is enhanced,which is a unique manifestation.

Objective:To evaluate the objective response rate (ORR) of induction chemoimmunotherapy with camrelizumab plus TPF (docetaxel, cisplatin, and capecitabine) for locally advanced hypopharyngeal squamous cell carcinoma (LA HSCC) and potential predictive factors for ORR.Methods:A single-center, prospective, phase 2 and single-arm trial was conducted for evaluating antitumor activity of camrelizumab+TPF(docetaxel+cisplatin+capecitabine) for LA HSCC between May 21, 2021 and April 15, 2023, patients admitted to the Eye & ENT Hospital affiliated with Fudan University. The primary endpoint was ORR, and enrolled patients with LA HSCC at T3-4N0-3M0 received induction chemoimmunotherapy for three cycles: camrelizumab 200 mg day 1, docetaxel 75 mg/m 2 day 1, cisplatin 25 mg/m 2 days 1-3, and capecitabine 800 mg/m 2 days 1-14. Patients were assigned to radioimmunotherapy when they had complete response or partial response (PR)>70% (Group A), or assigned to surgery plus adjuvant radiotherapy/chemoradiotherapy when they had PR≤70% (Group B), and the responses were defined by using tumor volume evaluation system. Tumor diameter was also used to assess the treatment responses by Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1. Use SPSS 23.0 software was used to analyze the data. Results:A total of 51 patients were enrolled who underwent the induced chemoimmunotherapy for three cycles, and all were males, aged 35-69 years old. After three cycles of induction immunochemotherapy, 42 (82.4%) patients existed in Group A (complete response or PR>70%) and 9 patients (17.6%) in Group B (PR≤70%), the ORR was 82.4%. The primary endpoint achieved expected main research objectives. Compared to the patients of Group A, the patients of Group B showed the higher T stage and the larger volume of primary tumor before induced immunochemotherapy, and also had the less regression of tumor volume after induced immunochemotherapy (all P<0.05). The optimal cutoff value of pre-treatment tumor volume for predicting ORR was 39 cm 3. The T stage ( OR=12.71, 95% CI: 1.4-112.5, P=0.022) and the volume ( OR=7.1, 95% CI: 1.4-36.8, P=0.018) of primary tumor were the two main factors affecting ORR rate of induction chemoimmunotherapy. Conclusion:The induction chemoimmunotherapy with camrelizumab plus TPF shows an encouraging antitumor efficacy in LA HSCC.

To establish a simple,convenient,sensitive,and specific method for rapid detection of Zi-ka virus(ZIKV),the whole genome sequences of ZIKV isolated from different times and regions were analyzed.The specific primers and probes were designed based on the screened target se-quences located in the conserved region of the ZIKV NS5 gene.By combining RT-LAMP isother-mal amplification technology and immunochromatography technology,a reverse transcription loop mediated isothermal amplification nucleic acid and flow visualization strip(RT-LAMP-VF)detec-tion method for ZIKV was established.The results showed that the method had good specificity and sensitivity.When the ratio of inner,outer,and ring primers(FIP∶LF∶F3)was 4∶2∶1,the detection method can specifically detect 102 copies/pL RNA transcripts or 2.15 pfu ZIKV at 61 ℃for 45 minutes,with no cross reaction with other flaviviruses such as Japanese encephalitis virus and classical swine fever virus.Other RNAs in blood tissue samples did not affect the sensitivity and specificity of RT-LAMP-VF,indicating that the method can be applied to clinical practice.The ZIKV RT-LAMP-VF detection method established in this study is easy to perform and does not require special instruments and equipment.It is particularly suitable for the rapid detection of ZIKV in grassroots units,providing technical support and material support for the establishment of on-site rapid detection and early warning and prediction systems for ZIKV disease.

Objective:To investigate the diagnostic efficacy of MRI-based or CT-based measurements and the combined evaluation methods for preoperative bone quality assessment in patients with cervical degenerative diseases.Methods:Patients who underwent spine surgery for cervical degenerative diseases at the Department of Orthopedics, Huashan Hospital, Fudan University from September 2020 to March 2022 with available preoperative X-ray, CT, MRI and dule energy X-Ray absorptiometry (DEXA) data were included in this study. Vertebral bone quality score (VBQ) based on MRI T1-weightedimages and CT Hounsfiled unit (HU) values of the cervical spine were measured, and a combined diagnostic formula based on the binary logistic regression was constructed. The patients were divided into normal bone mass (T≥-1.0) and osteopenia/osteoporosis groups (T<-1.0). The student's t-test and Chi-square test were performed for comparisons between groups. The Pearson correlation coefficient was also used to investigate the correlation between DEXA-T scores, cervical VBQ and CT HU values. In addition, receiver operating characteristic curve (ROC) were plotted to explore the diagnostic efficacy of VBQ, CT HU and their combined diagnosis. Meanwhile, the corresponding sensitivity and specificity were obtained. Results:A total of 71 patients were included in this study (17 in the normal group and 54 in the osteopenia/osteoporosis group). The student's t-test showed that VBQ (2.90±0.70 vs. 3.83±0.83, t=4.23, P<0.001) and CT HU values (370.26±85.38 vs. 295.20±67.96, t=3.73, P=0.002) were significantly different between the two groups. The area under the ROC curve (AUC) for VBQ and CT values of the cervical spine were 0.81 and 0.75, respectively, and the AUC for the combined diagnostic value constructed on the basis of both was 0.85. Applying VBQ scores alone had a diagnostic sensitivity of 80% and a specificity of 70%, and the combined diagnosis with VBQ and CT HU had a sensitivity of 90% and a specificity of 75%. Person correlation analysis showed a significant correlation between DEXA T value, cervical VBQ value and CT HU value. The detailed formula was: DEXA T score=-0.63×cervical VBQ+0.64 ( r=-0.55, P<0.001), CT HU value=-40.20×cervical VBQ+458.40 ( r=-0.45, P<0.001), DEXA T score=0.006×CT HU-3.47 ( r=0.45, P<0.001). Conclusion:This study confirmed the feasibility of using cervical VBQ values, CT HU values and combined diagnostics for preoperative bone density screening in patients with degenerative cervical spine diseases. This method allows surgeons to perform an initial preoperative bone density screening based on the patient's existing imaging data, and thus could aid in confirming the indication and scheme of surgery. The method could be a powerful tool for preoperative bone density assessment screening in patients with cervical degenerative diseases.

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.

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 evaluate the value of endogenous digitalis-like factor (EDLF) dynamic changes in predicting myocardial injury and prognosis in patients with sepsis.Methods:A total of 160 sepsis patients admitted to the emergency department of Beijing Friendship Hospital Affiliated to Capital Medical University from July 2017 to January 2019 were selected and divided into the myocardial injury(MI) group ( n=75) and the non-myocardial injury (NMI) group ( n=85) according to whether there was myocardial injury. The plasma EDLF concentration was tested on the 1 st, 3 rd and 7 th day after admission. The predictive factors of MI and 90-days outcome were evaluated by logistics regression analysis. Cox proportional hazards regression model was used to estimate the prognostic value of EDLF concentration on the 90 days after admission for sepsis. Results:Septic patients with MI had increased levels of myocardial enzymes, decreased left ventricular fractional shortening index (FS) and interventricular septum (IVS) amplitude and abnormal wall motion, when compared to NMI patients (all P<0.05). EDLF concentration on the 7 th day in the MI group was significantly lower than in the NMI group ( P=0.019). Logistic regression showed that EDLF 7 th was an independent protective factor for MI and 90-day mortality in sepsis respectively ( OR=0.964, 95% CI: 0.934-0.994, P=0.021; OR=0.931, 95% CI: 0.871-0.995, P=0.036). Cox proportional hazards regression analysis suggested that EDLF 7 th concentration <26.7 pmol/L was an independent predictor of 90-day mortality in patients with sepsis ( HR=4.601, 95% CI: 1.030-20.563, P=0.046). Conclusions:EDLF 7 th may serve as a protective factor for sepsis-induced MI and adverse outcome. The exogenous supplement of cardiotonic drugs at one week after MI may be a potential treatment to improve the survival rate of septic patients.

Objective:To investigate the effects of rapamycin (RAPA) on the cognitive function of lupus mice by regulating Cysteine rich 61 (Cyr61) and autophagy.Methods:MRL/lpr lupus mice were randomly divided into lupus group and rapamycin + lupus group, wild-type C57BL/6 mice were randomly divided into normal control group and rapamycin group with six mice in each group, RAPA + lupus group and rapamycin group were intraperitoneally injected with RAPA (2.0 mg/kg). The lupus group and the normal control group were injected with equal amounts of dimethyl sulfoxide (DMSO). Morris water maze was used to observe the cognitive function of mice. Western blotting was used to detect the expression of Cyr61, Programmed cell death-1 (Beclin-1), Microtubule associated protein 1 light chain3B (LC3B). Hematoxylin-eosin (HE) staining was used to observe the pathological changes in the hippocampus. The changes of neurons and bodies in hippocampus were observed by Nissl staining. The localization and expression of Cyr61 and LC3B in hippocampus were detected by immunofluorescence staining. One-way analysis of variance (ANOVA) was used between groups, and LSD-T test was used for pairwise comparison.Results:Western blotting results showed thatthe protein expression of Cyr61 (0.99±0.15) was significantly increased ( P=0.011), and the protein expression of Beclin-1 (0.64±0.04) and LC3B(0.54±0.05) was significantly decreased in lupus group ( P=0.025, P= 0.008) when compared with normal control group (0.73±0.08, 0.81±0.12, 0.80±0.03). The expressions of Cyr61 (0.75±0.05, 0.75±0.08), Beclin-1 (0.84±0.08, 0.92±0.04) and LC3B (0.93±0.16, 0.76±0.08) in rapamycin group and rapamycin + lupus group were not significantly changed ( P>0.05). Compared with rapamycin group, the protein expression of Cyr61 (0.99±0.15) was significantly increased ( P=0.016), and Beclin-1 (0.64±0.04), LC3B (0.54±0.05) was significantly decreased in lupus group ( P=0.013, P=0.001). The expressions of Cyr61 (0.75± 0.08), Beclin-1 (0.92±0.04) and LC3B (0.76±0.08) were not significantly changed in rapamycin+lupus group ( P=0.999, P=0.241, P=0.062). Compared with lupus group, the expression of Cyr61 (0.75±0.08) protein in rapamycin+lupus group was significantly decreased ( P=0.016), and the expression of Beclin-1 (0.92±0.04) and LC3B(0.76±0.08) protein were significantly increased ( P=0.002, P=0.017). Immunofluorescence results showed that Cyr61 and LC3B were mainly expressed in the cytoplasm of hippocampal neurons, and the quantitative detection results were consistent with western blot results, the differences were statistically significant ( P=0.025, P=0.032). HE staining showed that the levels and number of cells in the hippocampus of mice with lupus were reduced, and the arrangement was sparse, and the nuclei were hyperchromatic, showing nuclear pyknosis and migration. The results of Nissl staining showed that there were relatively fewer Nissl bodies, loose arrangement of neurons and vacuolar areas in some cells, which were improved after RAPA treatment in lupus mice. Conclusion:RAPA can protect the cognitive function of lupus mice by inhibiting the expression of Cyr61 in hippocampus and promoting autophagy.

Fusion surgery has been an effective modality for the treatment of spinal disorders for more than 100 years. With the increasing understanding of the disease and the increasing maturity of surgical techniques, lumbar fusion has become more widely performed and its efficacy has been conclusively proven. However, fusion surgery inevitably disrupts the original physiologic motion of the spine and limits segmental motion, resulting in a significant increase in disc and joint protrusion stress in adjacent segments. When a newly identified degenerative change on imaging is present in an adjacent segment or an existing degeneration is more aggravated, this is known as adjacent segment degeneration. When clinical symptoms such as pain and numbness in the lower extremities are present that are consistent with degeneration, this is known as adjacent segment disease. Real world studies (RWS) have become a major focus in medical research in recent years. Since it is closer to clinical practice and more practical for decision-making compared with randomized controlled trail (RCT), it is gaining importance in clinical practice. By searching major national and international databases, this article provides a review of risk factors as well as advances in the treatment of lumbar adjacent segment disease in RWS. According to the retrieved literature, there are many factors that contribute to the development and progression of adjacent segment degeneration and disease, which are mainly divided into patient-related factors and surgery-related factors. In general, patient age, weight, spinal-pelvic sagittal parameters, and internal diseases influence the progression of adjacent segment degeneration. Surgery-related risk factors include the number of segments operated on, the surgical approach, interference with adjacent segments, and whether the spinal-pelvicsagittal imbalance is corrected. To prevent the development of adjacent segment disease, patients can slow the progression of adjacent segment degeneration by reducing their own weight and controlling their internal diseases. The physician can also avoid the influence of surgery-related factors through adequate surgical planning and careful intraoperative management. At the same time, surgeries may be performed in patients who have developed adjacent segmental disease and for whom conservative treatment has failed. The current revision surgical approaches include endoscopic simple decompression and posterior decompression with extended internal fixation.Short-term RWS revealed that the efficacy of endoscopic treatment of adjacent spondylosis might be equivalent to re-fusion internal fixation surgery. Studies with large samples and long-term follow-up are still needed to guide the treatment of adjacent segment disease in the future, in order to improve clinical decision-making.

Objective:To evaluate the risk factors of acute kidney injury (AKI) in patients with multiple wasp stings.Methods:Patients with multiple wasp stings were retrospectively enrolled in Hanzhong Central Hospital from September 2010 to November 2020. Based on whether the patients developed AKI, the patients were divided into AKI group and non-AKI group. The general characteristics and laboratory examinations between the two groups were compared. The logistic regression model was used to analyze the risk factors of AKI.Results:A total of 356 patients with multiple wasp stings were recruited in this study, with 196 males (55.1%). The age was 56.0(45.0, 64.0) years old. There were 59 patients (16.6%) with hypertension and 13 patients (3.6%) with diabetes. There were 51 patients (14.3%) in the AKI group and 305 patients (85.7%) in the non-AKI group. Baseline data and biochemical examinations indicated that the two groups showed significant differences in gender, age, sting sites (systemic or local), sting needles, proportions of gross hematuria, leukocyte count, hemoglobin, creatine kinase, alanine transaminase, aspartate aminotransferase, total bilirubin, proportions of urinary protein, and proportions of urine occult blood (all P<0.05). The multivariate logistic regression analysis results showed that the increasing number of sting needles (every 10 needles increase, OR=1.866, 95% CI 1.289-2.071, P=0.001), gross hematuria ( OR=9.770, 95% CI 2.586-36.910, P=0.001), decreasing hemoglobin (every 1 g/L increase, OR=0.016, 95% CI 0.001-0.355, P=0.009), increasing aspartate aminotransferase (every 100 U/L increase, OR=1.311, 95% CI 1.144-1.502, P<0.001), and increasing total bilirubin (every 10 μmol/L increase, OR=1.200, 95% CI 1.008-1.430, P=0.041) were independent influencing factors of AKI. Conclusions:The increasing number of sting needles, gross hematuria, decreasing hemoglobin, increasing aspartate aminotransferase, and increasing total bilirubin are independent risk factors of AKI in patients with multiple wasp stings.
