OBJECTIVE To analyze the medication needs of parents of pediatric children in our hospital regarding drug instructions， and explore improvement strategies， thereby providing a basis for clinically guiding the rational use of drugs in pediatric patients. METHODS A self-designed questionnaire was used to randomly select the parents of pediatric patients in the pediatric outpatient and emergency departments of our hospital from July 1st to September 30th， 2024. A randomized face-to-face survey was conducted regarding their willingness to read drug instructions， their current understanding status， and their needs. The survey results were then statistically analyzed. RESULTS A total of 300 questionnaires were distributed in this survey， and 299 valid questionnaires were recovered， with an effective recovery rate of 99.7%. Before medication， the parents who “always” and “often” read the drug instructions in detail accounted for 39.1% （117 respondents） and 35.1% （105 respondents）， respectively. Statistically significant differences were observed in the willingness to read drug instructions among respondents with varying educational levels and occupations （P＜0.05）. Among the 299 respondents， only 48 people （16.1%）“ fully understood” the drug instructions， and the average understanding score of all the respondents was （3.77±0.83） points. The stronger the respondents’ willingness to read drug instructions， the higher their understanding scores of drug instructions （P＜0.05）. A total of 256 respondents thought that drug instructions were of great help to themselves， and the average helpfulness rating score of all the respondents was （4.28±0.78） points. Under the conditions of varying ages， educational levels， occupations， and willingness to read drug instructions， statistically significant differences were observed in the scores representing the degree of helpfulness of drug instructions to the respondents （P＜0.05）. Respondents paid the most attention to content in drug instructions such as “dosage and administration method”，“ adverse reactions”， and “indications and therapeutic categories”. The most difficult sections for them to understand included “chemical structure and properties”， “pharmacological and toxicological effects” ， and “pharmacokinetics”， etc. The demographic characteristics of the respondents were not significantly associated with the content areas of drug instructions they most desired to see improved （P＞0.05）. Most respondents （86.0%） hoped to improve the instructions mainly by “simplifying professional terms to make them more accessible”. Others included “highlighting key information” （60.5%） and “providing more detailed medication guidance” （49.2%）， etc. CONCLUSIONS Parents of pediatric patients in our hospital have a high demand for drug instructions but low comprehension. The pharmacy department should make targeted improvements to drug instructions based on parents’ actual needs， helping them accurately obtain medication knowledge and reduce potential medication safety risks.

OBJECTIVE To mine the adverse drug event （ADE） signals of sacituzumab govitecan and provide a reference for its clinical safety application. METHODS The data of sacituzumab govitecan-related ADE reports were collected from the FDA Adverse Event Reporting System （FAERS） database from April 1， 2020 to April 30， 2024. The reporting odds ratio（ROR） method， the United Kingdom Medicines and Healthcare Products Regulatory Agency comprehensive standard method （MHRA） and Bayesian confidence propagation neural network （BCPNN） method were used for data mining. Systematic organ classification （SOC） and preferred term （PT） in the ADE terminology set of version 27.0 of the Medical Dictionary for Regulatory Activities （MedDRA） were used for data classification and statistics. RESULTS A total of 753 ADE reports were obtained for sacituzumab govitecan， including 46 ADE signals， involving 12 SOCs， and 13 new suspicious ADE signals not recorded in the instructions. Top 5 PTs in terms of occurrence frequency were disease progression， death， diarrhea， off label use and inappropriate schedule of product administration. Top 5 PTs in terms of signal strength were febrile bone marrow aplasia， neutropenic colitis， disease progression， pulmonary sepsis， general physical condition abnormal. New ADE not recorded in the drug instructions included neutropenic sepsis， hepatic cytolysis， meningitis， aplasia， etc. CONCLUSIONS When using sacituzumab govitecan in clinical practice， special attention should be paid to ADE with highly reported cases and strong signal intensity， such as febrile neutropenia， febrile bone marrow aplasia， weight fluctuations， colitis. We should also be alert to new suspected ADE such as neutropenic sepsis， hepatic cytolysis， meningitis， and aplasia to ensure patient medication safety.

Objective:To compare the clinical efficacy of laparoscopic pelvic floor three-level internal repair and stapled transanal rectum resection (STARR) in the treatment of male patients with intrarectal prolapse. Mlethds A total of 101 male patients with rectal intrarectal prolapse from Feb 2013 to Oct 2017 were enrolled into this study. Fifty-two patient in group A received laparoscopic pelvie floor three-level internal repair, and 49 patients in group B received STARR. The Wexner incontinence scale (WIS), Wexner constipation scale (WCS) score, gastrointestinal quality of life index (GIQLI) and degree of internal rectal prolapse (DIRP) were systematically evaluated before surgery and 3 months, 1 year and 3 years after surgery. Results:There were no significant differences in age, BMI, number of bowel movements(BM), WIS, WCS, GIQLI and DIRP between the two groups before surgery(all P>0.05). The WIS, WCS, GIQLI and DIRP in 3 months, 1year and 3 years after surgery in both two groups were significantly better than those before surgery ( t=20.169, 25.229, 27.278, 23.818, 23.489, 21.152, -3.550, -23.042, -22.901, 82.852, 40.915, 30.010, 11.323, 13.237, 11.452, 19.473, 18.647, 17.108, -8.791, -5.254, -5.846, 37.439, 30.598, 22.852, all P<0.001). The GIQLI in Group A was significantly better than that of group B at 1 year and 3 years after surgery ( P<0.001) but close to that in Group B at 3 months after surgery ( t=1.428, P=0.156). The WIS, WCS and DIRP in group A were significantly better than those in group B at 3 months, 1 year and 3 years after surgery, with statistical significance ( t=-8.243, -15.688, -20.193, -4.268, -4.768, -4.851, 11.329, 13.543, -5.399, -4.745, -4.598, all P<0.001). There was no signifcant difference in grade Ⅰ-Ⅲ complications between the two groups (χ 2=0.046, P=1.00). Conclusion:Laparoscopic pelvic floor three-level internal repair is more effective than transanal STARR in the treatment of male internal rectal prolapse.

The understanding of heart embryonic development and structure can contribute to improve our leaning of the etiology, pathophysiology and classification of congenital heart disease in humans, which has become the focus of echocardiography teaching. Meanwhile the difficulties and problems formed because of its diverse and fragmented theoretical knowledge. "Hand as foot" teaching method is a kind of teaching method using intuitive body language combined with the thought of analogy, so as to make teaching content relatively simplistic and figurative. Our study has demonstrated this method can be used in a constructive way to improve course content and delivery for echocardiography teaching to assess patent foramen ovale for standardized residency training of cardiac ultrasound, and achieved a good teaching effect. The specific implementation approaches and effect of this method are described in detail. This paper also explores the potential feasibility and benefits of the application of using "Hand as foot" teaching method in echocardiography teaching.

Objective:To study the clinicopathological characteristics, diagnosis and differential diagnosis of bronchiolar adenoma (BA).Methods:Fifteen cases of BA were collected from the First Affiliated Hospital of Nanjing Medical University, from January 2016 to October 2019. The clinical data, imaging examination, morphology, immunostaining and molecular changes were retrospectively analyzed.Results:There were 3 males, 12 females, most of the patients were female, mainly in middle-aged to elderly (51-77 years). Three had smoking history. The patients usually had no clinical symptoms. Imaging findings were ground-glass and/or lobulated nodules. Grossly, the tumors were gray-whitish, taupe solid or focally microcystic nodules with distinct boundary but no capsule. The maximum diameter was 0.4-2.5?cm (mean 1.0?cm). Histologically, there were glandular, papillary, or flat patterns that were composed of basal cells, mucous cells, ciliated cells and type Ⅱ pneumocytes, some of which showed basal cell proliferation and squamous cell metaplasia. However, there were some cases with few or even without mucous and/or ciliated cells. Immunostaining highlighted the continuous basal cell layer (positive for p63, p40 and cytokeratin 5/6), which was the most important diagnostic evidence. Genetic tests did not show mutation in BRAF or EGFR genes. All patients were followed up for 1-41 months, and they were without recurrence or metastasis.Conclusions:BA is a benign neoplasm that develops in the peripheral lung with good prognosis. Definite diagnosis is very crucial for surgical treatment, especially in frozen consultation. Immunohistochemistry will be helpful if necessary.

Objective To study the application of laser speckle contrast algorithm in high-frequency ultrasound blood flow imaging. Methods The laser speckle contrast algorithm was extended to the field of high-frequency ultrasound blood flow imaging. The high-frequency ultrasound structure images were processed by using the classic laser speckle temporal contrast algorithm to suppress the static tissue signals, enhance the dynamic blood flow signals, and obtain the high-frequency ultrasound blood flow images. The simulation experiments on flow phantoms were conducted to verify the effectiveness of the algorithm, and then human skin tissue in vivo experiments were performed to verify the applicability of the algorithm. The performances of blood flow images which obtained from ultrasound structure images with different frames by laser speckle contrast algorithm were compared and analyzed. Results The blood flow information in a tube was clearly visible in the flow phantoms experiments. The static skin tissue signals were significantly suppressed, dynamic blood flow signals were strengthened in the human skin tissue in vivo experiments, and high-frequency ultrasound blood flow images were obtained. By comparing and analyzing the performances of blood flow images, the results showed that the best blood flow images could be obtained when the number of frame was set to 10 frames. Conclusions The speckle contrast algorithm is feasible and has good application prospects in high-frequency ultrasound blood flow imaging.

Objective To evaluate the left ventricular and right ventricular systolic function by two‐dimensional speckle tracking echocardiography ( 2D‐STE) in patients with rheumatoid arthritis ( RA ) . Methods Fifty five patients with RA and 50 healthy subjects were received echocardiography . 2D‐STE were applied for all the subjects to obtain left ventricular global longitudinal strain ( LVGLS) and right ventricular global longitudinal strain ( RVGLS) .Tricuspid annular plane systolic excursion ( TAPSE) and the change ratio of right ventricular area ( RVACR) were measured by echocardiography . The anti‐cyclic citrullinated peptide antibodies ( anti‐CCP‐II) ,rheumatoid factor ( RF) ,C‐reactive protein ( CRP) and erythrocyte sedimentation rate ( ESR) were detected in both group . The LVGLS and RVGLS in RA group were used to conduce correlation analysis with the level of anti‐CCP‐II ,RF ,CRP , ESR and the duration of disease . Results There was a significant decrease in RVGLS and LVGLS in RA group compared with control group( P <0 .05) . However there was no statistical differenc in TAPSE and RVACR between RA and control group( P > 0 .05) . The anti‐CCP‐II ,RF ,CRP and ESR in RA group increased significantly compared with control group ( P < 0 .001 ) . The result of correlation analysis showed there was no correlation between RVGLS ,LVGLS and anti‐CCP‐II ,RF ,CRP ,ESR in RA group . However ,RVGLS and LVGLS were negatively correlated with the duration of disease . Conclusions LVGLS and RVGLS in RA patients were lower than those in healthy people ,strain decreases with the extension of disease duration ,2D‐STE may be an efficacious assessment to assess left ventricular and right ventricular systolic function in patients w ith RA .
