【Objective】 To retrospectively analyze the indexes of autologous blood transfusion during heart valve replacement, in order to provide reference for allogeneic blood transfusion during heart valve replacement surgery under direct vision. 【Methods】 The data of 180 patients who underwent heart valve replacement in our hospital from January 2020 to December 2021 were analyzed retrospectively. The patients were divided into allogeneic and non-allogeneic blood transfusion group based on whether allogeneic blood was transfused during the operation, and the general data and 24 hours pre- and post-operative clinical examination indexes were compared. 【Results】 Multivariate logistic regression analysis showed that age (OR=1.110, 95% CI: 1.058-1.165, P<0.05) and intraoperative cardiopulmonary bypass time (OR=1.062, 95% CI: 1.038-1.086, P<0.05) were risk factors for allogeneic blood transfusion, and preoperative Hb content (OR=0.910, 95%CI: 0.868-0.953, P<0.05) was a protective factor. The RBC count(4.16±0.73 vs 4.52±0.71)×10¹²/L and Hb(120.94±17.97 vs 136.57±19.33) g/L at 24 hours preoperative in the allogeneic transfusion group were lower than those in the non-allogeneic transfusion group, and the RBC(3.51±0.53 vs 4.13±0.78)×10¹²/L, Hb(114.15±11.68 vs 124.79±14.96)g/L and platelet count(124.28±32.11 vs 148.29±26.62)×10⁹/L at 24 hours postoperative were significantly lower than those in the non-allogeneic transfusion group (P<0.05). 【Conclusion】 Age and intraoperative cardiopulmonary bypass time are the risk factors for autologous and allogeneic blood transfusion during heart valve replacement under direct vision, and the preoperative Hb content is a protective factor. It is necessary to evaluate the symptomatic treatment of patients before operation and reduce allogeneic blood transfusion.

To summarize the nursing care of a very low birth weight premature infant with severe type Ⅱbronchopulmonary dysplasia(BPD)during the transition period from hospitalization to home.The care of the infant was provided one-on-one by a BPD specialist nurse throughout the period.The key points of transitional care from hospitalization to home include:implementing tracheotomy and mechanical ventilation care to ensure stable blood oxygen saturation of the infant;providing nutritional support to improve the nutritional status of the infant;implementing step-by-step rehabilitation measures to improve the neuromotor development of the infant;implementing family integrated care to promote the primary caregivers of the infant to master nursing knowledge and skills;conducting personalized discharge follow-up with a multidisciplinary team to improve the quality of home care for this infant.After being hospitalized for 106 days,the infant was successfully discharged with a tracheotomy tube.At the age of 2 years and 6 months,a tracheotomy closure surgery was performed.After the surgery,the infant was able to breathe autonomously without symptoms of breathing difficulties and returned to normal family life.

This article focuses on a case study of sitosterolemia in a child who initially presented with hemolytic anemia and thrombocytopenia. Sitosterolemia is a rare autosomal recessive lipid metabolism disorder, difficult to diagnose due to its non-typical clinical manifestations. The 8-year-old patient was initially misdiagnosed with pyruvate kinase deficiency. Comprehensive biochemical and molecular biology analyses, including gene sequencing, eventually led to the correct diagnosis of sitosterolemia. This case highlights the complexity and diagnostic challenges of sitosterolemia, emphasizing the need for increased awareness and accurate diagnosis in patients presenting with similar symptoms.

Objective:To establish and verify a simple clinical prediction model for obstructive sleep apnea syndrome(OSAS)in children.Methods:The clinical data of 95 children aged 2-12 years underwent polysomnography(PSG)were screened.The subjects with OAHI≤1 were included into non-OSAS group(n=22)and those with OAHI＞1 into OSAS group(n=73).Gender,age,body mass index(BMI),night pulse minimum oxygen saturation(SpO2),tonsil grading and adenoid grading of the 2 groups were compared and analyzed.Binary Logistic regression analysis was used to statistically analyze the data and establish a clinical prediction model for OSAS in children.Results:There was significant difference in age,BMI,SpO2,tonsil grading and adenoid grading between the 2 groups(P＜0.05),there was no significant gender difference(P＞0.05).The model equation was as follows:X=2.366-0.769(age-continuous variable)+0.248(BMI-continuous variable)-3.413(SPO2-continuous variable)+2.104(tonsil grade Ⅲ-Ⅳ"yes").The result of internally validated Hosmer-Lemeshow test was P=0.612(P＞0.05),AUC was 0.821(0.713-0.929,P＜0.01),sensi-tivity was 83.3％,specificity was 76.4％.The accuracy of external validation was 73.8％,the AUC was 0.805(0.664-0.943,P＜0.01),the sensitivity was 84.6％and the specificity was 75％.Conclusion:The predictive model may have good predictive efficacy for 2-12 years old children with OSAS,and may assist clinicians in diagnosing children with OSAS.

Objective:To investigate the criteria for two-way referral of diabetes in China through systematic review.Methods:According to inclusion and exclusion criteria, articles on two-way referral criteria for diabetes in China were retrieved from databases of PubMed, Embase, Cochrane Library, CNKI and Wanfang from inception to July 15, 2023. The data were extracted, by author′s name, publish year, criteria for rupwards and downwards referral, sample size, study region, study type and main conclusions.Results:A total of 702 relavent articles were retrieved, and 15 of which were included in the analysis. Blood glucose levels were the basic criteria for two-way referral, The criteria for upward referral included fasting blood glucose, 2-h postpradial blood glucose, glycosylated hemoglobin and random blood glucose, but there were variations in measuement values. The criteria for downward referral included fasting blood glucose, 2-h postpradial blood glucose, glycosylated hemoglobin, with the variation in fasting blood glucose. Lipids and blood pressure were also included in the referral criteria in later literature, with the variation of blood pressure values. There was consensus on the upward referral criteria for patients with special types of diabetes and with newly diagnosed diabetes. In contrast, the referral criteria for diabetic complications were relatively vague, especially with the lack of severity classification for chronic complications.Conclusion:The two-way referral criteria for diabetes mellitus have been constantly developing, while the criteria for downwards referral to the community need to be further improved.

Objective:To evaluate the efficacy and safety of mitoxantrone hydrochloride liposome injection in the treatment of peripheral T-cell lymphoma (PTCL) in a real-world setting.Methods:This was a real-world ambispective cohort study (MOMENT study) (Chinese clinical trial registry number: ChiCTR2200062067). Clinical data were collected from 198 patients who received mitoxantrone hydrochloride liposome injection as monotherapy or combination therapy at 37 hospitals from January 2022 to January 2023, including 166 patients in the retrospective cohort and 32 patients in the prospective cohort; 10 patients in the treatment-na?ve group and 188 patients in the relapsed/refractory group. Clinical characteristics, efficacy and adverse events were summarized, and the overall survival (OS) and progression-free survival (PFS) were analyzed.Results:All 198 patients were treated with mitoxantrone hydrochloride liposome injection for a median of 3 cycles (range 1-7 cycles); 28 cases were treated with mitoxantrone hydrochloride liposome injection as monotherapy, and 170 cases were treated with the combination regimen. Among 188 relapsed/refractory patients, 45 cases (23.9%) were in complete remission (CR), 82 cases (43.6%) were in partial remission (PR), and 28 cases (14.9%) were in disease stabilization (SD), and 33 cases (17.6%) were in disease progression (PD), with an objective remission rate (ORR) of 67.6% (127/188). Among 10 treatment-na?ve patients, 4 cases (40.0%) were in CR, 5 cases (50.0%) were in PR, and 1 case (10.0%) was in PD, with an ORR of 90.0% (9/10). The median follow-up time was 2.9 months (95% CI 2.4-3.7 months), and the median PFS and OS of patients in relapsed/refractory and treatment-na?ve groups were not reached. In relapsed/refractory patients, the difference in ORR between patients with different number of treatment lines of mitoxantrone hydrochloride liposome injection [ORR of the second-line, the third-line and ≥the forth-line treatment was 74.4% (67/90), 73.9% (34/46) and 50.0% (26/52)] was statistically significant ( P = 0.008). Of the 198 PTCL patients, 182 cases (91.9%) experienced at least 1 time of treatment-related adverse events, and the incidence rate of ≥grade 3 adverse events was 66.7% (132/198), which was mainly characterized by hematologic adverse events. The ≥ grade 3 hematologic adverse events mainly included decreased lymphocyte count, decreased neutrophil count, decreased white blood cell count, and anemia; non-hematologic adverse events were mostly grade 1-2, mainly including pigmentation disorders and upper respiratory tract infection. Conclusions:The use of mitoxantrone hydrochloride liposome injection-containing regimen in the treatment of PTCL has definite efficacy and is well tolerated, and it is a new therapeutic option for PTCL patients.

Objective:To explore the influencing factors of seasonal influenza among pregnant woman in Suzhou from 2015 to 2018.Methods:Based on the data of the influenza follow-up cohort of pregnant women in Suzhou from 2015 to 2018, the basic and clinical characteristics of the cohort were described, and the influencing factors of laboratory-confirmed influenza cases in pregnant women were analyzed by unconditional logistic regression.Results:A total of 19 006 pregnant women were recruited, in whom 479 cases of influenza were laboratory confirmed. Influenza A (H3N2) (42.8%) was the main sub-type. In pregnant women with exposure risk in influenza season, unconditional univariate logistic analysis showed that pregnant women or their husbands had registered permanent residence in Suzhou, pregnant women worked as childminder or nanny, had more than 2 permanent residents in the family except themselves, had medical insurance in Suzhou, had fertility insurance in Suzhou, were in the third trimester at the time of enrollment, had cough in the past month, were pregnant for the first time, had children, before and after pregnancy, spent more time outdoors than before, wore masks more often than before and had changed the frequency of gathering were all related to influenza virus infection in pregnant women. Among them, the first pregnancy, increasing the time of outdoor activity, increasing the frequency of wearing masks, and changing the frequency of gathering were important protective factors. Unconditional multivariate logistic regression analysis showed that the number of permanent residents at home was >2 (a OR=1.24, 95% CI: 1.01-1.52) and being in the third trimester, (a OR=1.56, 95% CI: 1.26-1.91) were the risk factors for maternal infection with influenza virus. Conclusion:Pregnant women with a large number of permanent residents and late pregnancy should pay attention to preventing seasonal influenza.

Objective:To understand the reinfection rate of 2019-nCoV in the previously infected population in Suzhou and compare the illness severity and prognosis of the reinfection cases with the first-time infection cases.Methods:A questionnaire survey was conducted in the persons with previous 2019-nCoV infection reported in Suzhou from January 22, 2020 to November 8, 2022 to collect the information about the incidence of reinfection of 2019-nCoV in this population from December 8, 2022 to January 18, 2023. The persons who were infected with 2019-nCoV for the first time were selected by marching the residence, age and gender at ratio of 1∶2 from 2019-nCoV infection community follow-up cohort of Suzhou. By χ2 test, the clinical symptoms and prognosis of the reinfection case and the first-time infection cases were compared. Results:The reinfection rate of 2019-nCoV was 13.01% (147/1 130) in Suzhou. No reinfection was found within 1-6 months after the first-time infection, the rate of reinfection was 10.59% (95/897) in those with interval of 7-12 months between the reinfection and the first-time infection and 45.61% (52/114) in those with the interval ≥24 months. The lowest reinfection rate was 9.09% (1/11) in those who had completed 4 doses of 2019-nCoV vaccination. The main symptoms of the reinfection cases were similar to those of the first-time infection cases. Except for dry cough, nausea/poor appetite and other symptoms, there were significant differences in other clinical symptoms between the two groups ( P<0.05). In the reinfection cases, fever had shorter duration with lower body temperature. The hospital visit rate in the reinfection cases was 4.08% (6/147), lower than that in the cases with the first-time infection (11.56%, 34/294). The time for negative nucleic acid (antigen) test result and recovery from illness after the reinfection were shorter than those after the first-time infection. Conclusions:Reinfection occurred in some people who had been infected with 2019-nCoV. The interval between the reinfection and the first-time infection and the completion of the 4 doses of booster vaccination were the factors influencing the reinfection rate. The hospital visit rate in the reinfection cases was lower than that in the cases with the first-time infection. The reinfection had similar symptoms and shorter illness duration compared with the first-time infection.

Objective:To explore the value of contrast-enhanced ultrasound (CEUS) combined with Ovarian-Adnexal Reporting and Data System (O-RADS US) risk stratification and management system in differential diagnosis of ovarian-adnexal mass.Methods:Fifty-six patients with ovarian-adnexal mass who received transabdominal transvaginal ultrasound and CEUS in the Third People′s Hospital of Longgang District from September 2018 to January 2021 were enrolled. The images were classified by O-RADS US and diagnosed by CEUS by experienced and senior radiologist. On the basis of O-RADS US classification, the enhancement time, enhancement level and enhancement mode of CEUS were combined to upgrade or degrade the classification results of O-RADS US. The diagnostic accuracy was assessed using ROC curve analysis, the area under the ROC curve (AUC) was calculated. The reproducibility of O-RADS US was assessed by another senior radiologist.Results:The AUC of O-RADS US for diagnosing benign and malignant ovarian-adnexal masses was 0.844(0.722, 0.927), the AUC of CEUS was 0.833(0.710, 0.920), the AUC of O-RADS US combined with CEUS was 0.940(0.842, 0.986) (compared with O-RADS US, P=0.020; compared with CEUS, P=0.031). The intra-class correlation coefficient (ICC) was 0.897(0.824, 0.940) for O-RADS US. Conclusions:CEUS combined with O-RADS US classification can effectively improve the diagnostic efficiency for benign and malignant ovarian-adnexal masses.

Objective:To build a performance appraisal system for full-time researchers in specialized children′s hospitals, so as to mobilize their enthusiasm and improve their efficiency of scientific and technological output.Methods:Based on structure-process-result model, the library of indexes was initialized by such means as literature review and talent performance appraisal management experiences. From November 2020 to March 2021, Delphi method was adopted to finalize the appraisal indexes and weight of each index, while the quantifiable standards of the indexes were formulated by brainstorming, hence establishing the performance appraisal model index system for these researchers. Using both the new model and the original performance appraisal system of the hospital respectively, five full-time research staffs of research-oriented children′s hospital were selected for an empirical research on performance appraisal.Results:Fifteen experts carried out two rounds of Delphi research, finalizing a performance appraisal model for these researchers. The model comprises 3 level-1 indexes, 8 level-2 indexes and 23 level-3 indexes. Among them, the weight of scientific research output, scientific research process and scientific research investment of level-1 indexes were 0.507, 0.267 and 0.226, respectively. Empirical research showed that compared with the original appraisal indexes, the results of the new performance appraisal model were more targeted, enabling the research team to identify setbacks.Conclusions:The indexes set in the model built in this study prove more scientific, objective, and more reasonable in weight assignment. Such indexes can positively motivate and encourage the researchers, promoting the clinical-basic research integration, as well as the disciplinary development and research talent cultivation of the hospital.
