Objective To compile nursing guidelines for diabetic patients undergoing ultrasound-guided islet transplantation through percutaneous portal vein puncture and catheterisation,providing valuable insights for the care of such patients during the surgical procedure.Methods Between December 2017 to September 2023,a total of 27 patients underwent 44 surgical procedures for ultrasound-guided islet transplantation via percutaneous portal vein puncture and catheterisation at our hospital.Nursing assistance was provided preoperatively,intraoperatively and postoperatively for all the procedures.Results All 27 patients who had undergone 44 surgical procedures successfully went through the ultrasound-guided islet transplantation via percutaneous portal vein puncture and catheterisation.Among the 44 surgical procedures,3(6.8%)resulted in upper abdominal and liver area pain,nausea and vomiting during surgery,8(18.2%)had transient increase of portal vein pressure during transplantation,and 6(13.6%)encountered active bleeding following the removal of the portal vein catheters.None of the patients developed delayed portal vein bleeding or complication such as portal vein thrombosis after the surgery.Conclusions Nursing interventions play a crucial role in ensuring the successful outcomes of ultrasound-guided islet transplantation.Following measures are the keys and they play an important roles in ensuring the smooth completion of ultrasound-guided islet transplantation:preoperatively,carefully assess the condition of recipients and provide them with psychological supports and patient education.Intraoperatively,closely monitor the vital signs,portal vein pressure and blood glucose as well as to prevent complications.Postoperatively,implement the nursing measures to prevent the recipients from postoperative bleeding of portal vein.

Objective:To analyze the factors affecting delayed chemotherapy in children with Burkitt lymphoma (BL) and their influence on prognosis.Methods:Retrospective cohort study. Clinical data of 591 children aged ≤18 years with BL from May 2017 to December 2022 in China Net Childhood Lymphoma (CNCL) was collected. The patients were treated according to the protocol CNCL-BL-2017. According to the clinical characteristics, therapeutic regimen was divided into group A, group B and group C .Based on whether the total chemotherapy time was delayed, patients were divided into two groups: the delayed chemotherapy group and the non-delayed chemotherapy group. Based on the total delayed time of chemotherapy, patients in group C were divided into non-delayed chemotherapy group, 1-7 days delayed group and more than 7 days delayed group. Relationships between delayed chemotherapy and gender, age, tumor lysis syndrome before chemotherapy, bone marrow involvement, disease group (B/C group), serum lactate dehydrogenase (LDH) > 4 times than normal, grade Ⅲ-Ⅳ myelosuppression after chemotherapy, minimal residual disease in the interim assessment, and severe infection (including severe pneumonia, sepsis, meningitis, chickenpox, etc.) were analyzed. Logistic analysis was used to identify the relevant factors. Kaplan-Meier method was used to analyze the patients' survival information. Log-Rank was used for comparison between groups.Results:Among 591 patients, 504 were males and 87 were females, the follow-up time was 34.8 (18.6,50.1) months. The 3-year overall survival (OS) rate was (92.5±1.1)%,and the 3-year event-free survival (EFS) rate was (90.5±1.2)%. Seventy-three (12.4%) patients were in delayed chemotherapy group and 518 (87.6%) patients were in non-delayed chemotherapy group. The reasons for chemotherapy delay included 72 cases (98.6%) of severe infection, 65 cases (89.0%) of bone marrow suppression, 35 cases (47.9%) of organ dysfunction, 22 cases (30.1%) of tumor lysis syndrome,etc. There were 7 cases of chemotherapy delay in group B, which were seen in COPADM (vincristine+cyclophosphamide+prednisone+daunorubicin+methotrexate+intrathecal injection,4 cases) and CYM (methotrexate+cytarabine+intrathecal injection,3 cases) stages. There were 66 cases of chemotherapy delay in group C, which were common in COPADM (28 cases) and CYVE 1 (low dose cytarabine+high dose cytarabine+etoposide+methotrexate, 12 cases) stages. Multinomial Logistic regression analysis showed that the age over 10 years old ( OR=0.54,95% CI 0.30-0.93), tumor lysis syndrome before chemotherapy ( OR=0.48,95% CI 0.27-0.84) and grade Ⅲ-Ⅳ myelosuppression after chemotherapy ( OR=0.55,95% CI 0.33-0.91)were independent risk factors for chemotherapy delay.The 3-year OS rate and the 3-year EFS rate of children with Burkitt lymphoma in the delayed chemotherapy group were lower than those in the non-delayed chemotherapy group ((79.4±4.9)% vs. (94.2±1.1)%, (80.2±4.8)% vs. (92.0±1.2)%,both P<0.05). The 3-year OS rate of the group C with chemotherapy delay >7 days (42 cases) was lower than that of the group with chemotherapy delay of 1-7 days (22 cases) and the non-delay group (399 cases) ((76.7±6.9)% vs. (81.8±8.2)% vs. (92.7±1.3)%, P=0.002).The 3-year OS rate of the chemotherapy delay group (9 cases) in the COP (vincristine+cyclophosphamide+prednisone) phase was lower than that of the non-chemotherapy delay group (454 cases) ((66.7±15.7)% vs. (91.3±1.4)%, P=0.005). Similarly, the 3-year OS rate of the chemotherapy delay group (11 cases) in the COPADM1 phase was lower than that of the non-chemotherapy delay group (452 cases) ((63.6±14.5)% vs. (91.5±1.3)%, P=0.001). Conclusions:The delayed chemotherapy was related to the age over 10 years old, tumor lysis syndrome before chemotherapy and grade Ⅲ-Ⅳ myelosuppression after chemotherapy in pediatric BL. There is a significant relationship between delayed chemotherapy and prognosis of BL in children.

Background Adverse drug reactions (ADRs) to sodium dimercaptosulphonate (DMPS) mercury removal treatment have been reported in occupational mercury poisoning. In recent years, the number of cases of mercury poisoning due to mercury-containing cosmetics has been increasing, and ADRs to the use of DMPS are common in clinical practice. Objective To investigate the occurrence of ADRs and the influencing factors in patients with chronic mercury poisoning and mercury exposure treated with DMPS for mercury removal. Methods Patients treated with DMPS due to mercury poisoning at the Occupational Disease Department of Nanjing Prevention and Treatment Center for Occupational Diseases from June 2017 to December 2023 were included in the study. Information on demographics, baseline characteristics, and treatment regimens was collected at admission. Information on secondhand smoke, place of residence, and blood groups not collected at admission was collected in follow-up. The patients were divided into two groups according to whether ADRs occurred after the use of DMPS and were compared for clinical characteristics, and the influencing factors related to the occurrence of ADRs after DMPS treatment were analyzed by binary logistic regression. Results A total of 72 patients were enrolled in the study, of which 26 reported ADRs during mercury removal. A total of 29 ADRs occurred, mainly rash in 11 cases (37.9%), fever in 5 cases (17.2%), and nausea in 4 cases (13.8%). Most ADRs occurred in the second course (7 cases, 26.9%) and the third course (9 cases, 34.6%). Of the 22 non-menopausal women who experienced ADRs, 13 (59.1%) used DMPS in the week prior to menstruation. The logistic regression analysis showed that smoking (OR=27.911, 95%CI: 2.835, 725.809) and blood type O (OR=6.885, 95%CI: 2.014, 26.896) were associated with elevated occurrence of ADRs after DMPS treatment. Conclusions The probability of ADRs after DMPS treatment is not low, but mild presentations are predominant and resolved with immediate treatment, with a favourable prognosis. The O blood group, smoking individuals, and female patients using DMPS one week before menstruation may be more prone to ADRs.

This article presents a case of acute ST-segment elevation myocardial infarction (STEMI) in a pregnant woman caused by coronary artery dissection. The 41-year-old patient had undergone cardiac valve surgery at the age of 1 and had no risk factors such as hypertension, diabetes, smoking, alcohol use, or a family history of coronary artery disease. At 31 +1 weeks of gestation, she experienced sudden chest pain for 4 hours and was emergently referred to Peking University First Hospital on June 1, 2021. Electrocardiogram revealed ST-segment elevation in leads I, aVL, and V 2 to V 6. Biochemical assays showed elevated levels of high-sensitivity cardiac troponin I and creatine kinase-MB. Echocardiography indicated segmental ventricular wall motion abnormalities (apical) and reduced left ventricular function, confirming the diagnosis of acute anterior wall STEMI. The patient promptly underwent emergency coronary angiography and percutaneous coronary intervention and confirmed coronary artery dissection. Postoperative care included antiplatelet, anticoagulation, and supportive treatment. At 34 +3 weeks of gestation, with the condition of acute anterior wall STEMI being relatively stable, a cesarean section was successfully performed. Regular cardiology follow-ups were scheduled postpartum, and cardiac function was normal in two years after discharge.

Objective:To analyze the phenotype and genotype of congenital myasthenic syndrome type 10 (CMS10) caused by DOK7 gene mutation, and to conduct a literature review and summary of this disease. Methods:A retrospective analysis of the clinical characteristics and genetic test results of a patient with CMS10 in Affiliated Nanjing Brain Hospital, Nanjing Medical University in January 2020 was conducted. Whole exon sequencing was applied to high-throughput screen the pathogenic gene in this patient. After finding candidate variants, pathogenic classification was done according to the American College of Medical Genetics and Genomics and the Association for Molecular Pathology guideline. Sanger sequencing was applied to verify the mutation. Then all patients with DOK7 gene mutations were summarized by searching the literatures through PubMed, CNKI and Wanfang database. Results:The patient was a 51-year-old man who clinically presented with fluctuating quadriparesis and respiratory distress. He was diagnosed as CMS10 with compound mutations in DOK7 (c.1296_1311del16/c.332-1G>A) by clinical information and whole exon and Sanger sequencing. And c.332-1G>A was found to be a novel mutation. Literature review showed that patients with CMS10 with DOK7 gene mutations presented dominant weakness in proximal limbs and axial muscles. Patients with CMS10 would show periodic exacerbation in disease duration with slow progression. Among 71 mutations, frameshift mutation was the most frequent type (38.0%, 27/71), followed by missense mutation (32.4%, 23/71). Exon 7 (35.2%, 25/71) and exon 4 (26.8%, 19/71) were the hotspot regions. c.1124_1127dupTGCC was the most frequent mutation (43.2%, 140/324). The age of onset in patients with homozygous c.1124_1127dupTGCC was older than that in patients with compound heterozygous c.1124_1127dupTGCC [7.5(3.6, 19.8) years vs 1.3(0, 3.8) years, U=350.000, P<0.001]. Conclusions:CMS10 is a slowly progressive autosomal recessive genetic disease characterized by fluctuating muscle weakness, with muscle weakness distribution similar to limb-girdle muscular dystrophy. Frameshift mutation is the most common type in DOK7 gene associated CMS10. c.1124_1127dupTGCC in C-terminal is the most frequent mutation. Early identification of DOK7 gene associated CMS10 is crucial for the treatment and prognosis of this disease.

Background::The APPEC study is a large-population randomized controlled trial in China evaluating the role of low-dose aspirin prophylactic treatment for pre-eclampsia. There was no statistically significant difference in postpartum hemorrhage (PPH) incidence between the aspirin and control groups. This study aimed to evaluate the potential bleeding risk of 100 mg aspirin in high-risk pregnant women and the difference in the incidence of PPH according to maternal characteristics.Methods::This is a secondary data analysis of the APPEC study. Platelet counts and coagulation test results were collected at five follow-up visits. Subgroups defined by maternal age (<35 years and ≥35 years), pre-pregnancy body mass index (pre-BMI, <28 kg/m 2 and ≥28 kg/m 2), parity, gestational age at enrollment, and medical history, including pre-eclampsia, chronic hypertension, and diabetes mellitus, were analyzed. Logistic regression analysis was used to determine the statistical significance of the difference in the incidence of PPH after aspirin administration in pregnant women in each subgroup. Adjustment using multiple logistic regression models followed these analyses. Binary logistic regression was used to determine the relationship between pre-BMI and PPH. Results::There was no significant difference between the aspirin and control groups in bleeding risk (3.4% [16/464] vs. 3.0% [13/434], T = 0.147, P = 0.701). No significant difference was found in the incidence of PPH in total (relative risk = 1.220, 95% confidence interval [CI] = 0.720–2.067, P = 0.459; aspirin group vs. control group, 6.5% [30/464] vs. 5.3% [23/434], P = 0.459) or in subgroup analysis. A significant correlation between pre-BMI and PPH was found in the aspirin group, while in the control group there was no significant correlation (aspirin group, odds ratio [OR] = 1.086, 95% CI = 1.004–1.175, P = 0.040; control group, OR= 1.060, 95% CI = 0.968–1.161, P = 0.209). Conclusions::A dosage of 100 mg of aspirin per day, initiated from 12 to 20 gestational weeks until 34 weeks of gestation, did not increase the risk of potential bleeding and PPH regardless of the maternal characteristic. In the aspirin group, the positive correlation between BMI and PPH was significant.Trial Registration::ClinicalTrials.gov, NCT01979627.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has spread worldwide and threatened human's health. With the passing of time, the epidemiology of coronavirus disease 2019 evolves and the knowledge of SARS-CoV-2 infection accumu-lates. To further improve the scientific and standardized diagnosis and treatment of maternal SARS-CoV-2 infection in China, the Chinese Society of Perinatal Medicine of Chinese Medical Association commissioned leading experts to develop the Recommendations for the Diagnosis and Treatment of Maternal SARS-CoV-2 Infection under the guidance of the Maternal and Child Health Department of the National Health Commission. This recommendations includes the epidemiology, diagnosis, management, maternal care, medication treatment, care of birth and newborns, and psychological support associated with maternal SARS-CoV-2 infection. It is hoped that the recommendations will effectively help the clinical management of maternal SARS-CoV-2 infection.
