OBJECTIVE To provide evidence for the safe clinical application of Trastuzumab for injection. METHODS Reports of adverse drug reaction （ADR） related to Trastuzumab for injection submitted in Beijing from June 2018 to May 2023 were collected. Statistical analyses were performed using SPSS 25.0 software. The gender and age of patients with ADRs， outcome， types of cancer， and the time of onset， severity， affected organs/systems of ADRs were included for analyses. The univariate Logistic regression analysis was conducted on patient fever and ADR prognosis. RESULTS A total of 195 patients with 318 instances of ADRs were included in the study. Women （87.69%） and patients aged 60-69 （33.85%） were more likely to experience ADRs. Breast cancer dominated （86.67%） in terms of cancer types； in terms of outcomes， most patients （67.69%） showed improvement， and some patients （27.69%） achieved full recovery. Overall， 68.72% of ADRs mainly occurred on the day of medication， and 95.38% of ADRs were of “moderate” severity. The most affected organs/systems were general diseases and various reactions at the administration site （40.57%）， with chills （18.87%） and fever （18.24%） being the most common. Univariate Logistic regression analysis showed that fever mostly occurred within 1 day of medication （OR＝5.63， 95%CI was 2.26-14.02， P＜ 0.001）. The time of onset of ADR greater than 1 day was a risk factor for poor ADR prognosis （OR＝20.08， 95%CI was 2.45- 164.43， P＝0.005）， mainly manifesting as bone marrow suppression and liver function abnormalities. Neutrophilia， cardiorespiratory arrest， and mixed liver damage were new ADRs not recorded in the drug’s instructions. CONCLUSION Women and patients aged ≥60 are high-risk groups for ADRs of Trastuzumab for injection. Chills and fever remain the most common ADRs of this drug， and these symptoms mostly occur within 1 day of medication， which have better prognoses. Close attention should be paid to the patient’s temperature changes on the day of drug infusion， with timely intervention. Regular monitoring of the patient’s hematological indicators is necessary to detect any bone marrow suppression and liver function abnormalities after medication.

Objective To develop Pregnant Women Weight Self-Management Scale and test its reliability and validity.Methods Based on the concepts and theories of self-management,the first draft of the scale was formed through literature analysis,semi-structured interviews,2 rounds of Delphi expert correspondence and pre-surveys.The scale was used to test the reliability and validity of the scale by facilitating the selection of 300 pregnant women who gave birth in April 18-23 2023 at a maternal and child healthcare hospital in Ningxia Hui Autonomous Region.Results The Pregnant Women Weight Self-Management Scale consisted of 8 dimensions and 38 entries with a cumulative variance contribution of 68.560％.The Cronbach's alpha coefficient for the total scale was 0.944,and each dimension ranged from 0.772 to 0.929.The split-half reliability for the total was 0.858,and each dimension ranged from 0.715 to 0.902.The content validity index at the level of the total scale was 0.921,and at the level of each entry was from 0.833 to 1.000.There was a positive correlation between the dimensions and with the total scale score(r=0.178～0.854,P＜0.001).Conclusion The scale has good reliability and validity,and it can be used as a tool to evaluate the self-management ability of pregnant women.

Objective:To summarize the clinical features, electroencephalogram (EEG) and magnetoencephalogram (MEG) of patients with pure paroxysmal kinesigenic dyskinesia (PKD) and PKD with epilepsy, so as to better distinguish them and guide the treatments.Methods:The clinical data of 200 patients diagnosed with PKD in the Outpatient Department of Xuanwu Hospital, Capital Medical University from 2000 to 2023 were analyzed retrospectively. The patients were divided into 2 groups: pure PKD (174 cases) and PKD with epilepsy (26 cases) according to whether accompanied by epilepsy. The differences in clinical features, drug therapy, EEG and MEG were compared between the 2 groups.Results:The clinical features of the 2 groups were essentially similar, and the proportion of PKD dyskinesia induced by emotional stress in the pure PKD group (54/174, 31.03%) was higher than that in the PKD with epilepsy group (2/26, 7.69%; χ 2=5.010, P=0.025). In terms of pharmacological response, carbamazepine was the most commonly used medication in both groups, but patients with PKD with epilepsy may need a higher therapeutic dosages (0.2-0.4 g/d, and gradually increased to 0.8 g/d) to effectively manage both dyskinesia and seizures. Regarding the EEG and MEG, the proportion of EEG abnormalities was higher in PKD patients with epilepsy, mainly manifested as focal spikes [1/70(1.43%) vs 9/21(42.86%), χ 2=24.268, P<0.001], together with aberrant MEG discharge (4/18 vs 3/5, χ 2=1.155, P=0.282). The MEG dipoles were mainly distributed in the brain regions close to the frontal lobe and central region. Conclusions:The clinical manifestations of motor symptoms of pure PKD and PKD with epilepsy are similar, and carbamazepine remains the most effective treatment. PKD patients with epilepsy have a higher proportion of abnormal EEG, mainly manifested as focal spikes, and are more likely to show abnormal discharge of MEG, which could be used to distinguish them.

Objective:To screen the factors influencing overall survival (OS) of patients undergoing radical resection for colorectal cancer (CRC) and to construct a prognostic model for OS of patients after CRC.Methods:The clinical data of 350 patients with stage Ⅰ-Ⅳ CRC who underwent radical resection in the People's Hospital of Wuhan University from March 2017 to December 2019 were collected retrospectively. Patients were divided into subgroups 0 ( n=70), 1 ( n=172), and 2 ( n=108) according to different preoperative systemic inflammation score (SIS). The relationship between different SIS, neutrophil to lymphocyte ratio (NLR), lymphocyte to monocyte ratio (LMR), systemic immune inflammation index (SII) and prognosis of CRC patients undergoing radical surgical resection were analyzed, and Cox regression models were used to perform univariate and multifactorial analyses of factors affecting patient prognosis, and column line graph models were constructed based on the results of multifactorial analyses. Results:By the deadline of follow-up, 80 of 350 CRC patients died, and the 5-year OS rate was 77.14%. The 5-year survival rates of patients in SIS group 0, group 1 and group 2 were 95.71%, 79.65% and 61.11% respectively, with a statistically significant difference ( χ2=30.19, P<0.001). Statistically significant differences in age ( χ2=19.40, P<0.001), tumor site ( χ2=8.18, P=0.017), T stage ( χ2=10.01, P=0.007), TNM stage ( χ2=14.80, P=0.001), tumor diameter ( χ2=13.91, P=0.001) and carcino-embryonic antigen (CEA) level ( χ2=10.12, P=0.006) among patients in SIS group 0, group 1 and group 2. The 5-year OS rates of patients in the low NLR and high NLR groups were 82.67% and 56.16% respectively, with a statistically significant difference ( χ2=24.96, P<0.001) ; the 5-year OS rates of patients in the low LMR and high LMR groups were 66.85% and 88.17% respectively, with a statistically significant difference ( χ2=22.45, P<0.001) ; the 5-year OS rates of patients in the low SII and high SII groups were 86.14% and 69.02% respectively, with a statistically significant difference ( χ2=14.76, P<0.001). Univariate analysis showed that age ( HR=2.58, 95% CI: 1.54-4.32, P<0.001), T stage ( HR=2.41, 95% CI: 1.24-4.68, P=0.009), N stage ( HR=3.03, 95% CI: 1.85-4.94, P<0.001), TNM stage ( HR=3.61, 95% CI: 2.15-6.04, P<0.001), nerve invasion ( HR=1.97, 95% CI: 1.27-3.08, P=0.002), vascular invasion ( HR=2.31, 95% CI: 1.49-3.59, P<0.001), preoperative SIS 1 score ( HR=5.09, 95% CI: 1.57-16.56, P=0.007), SIS 2 score ( HR=11.05, 95% CI: 3.42-35.65, P<0.001), NLR ( HR=2.97, 95% CI: 1.90-4.64, P<0.001), LMR ( HR=0.31, 95% CI: 0.19-0.52, P<0.001), and SII ( HR=2.50, 95% CI: 1.54-4.06, P<0.001) were all independent influence factors affecting the postoperative prognosis of CRC patients undergoing radical surgical resection; multivariate analysis showed that age >60 years ( HR=2.27, 95% CI: 1.31-3.91, P=0.003), TNM stage Ⅲ-Ⅳ ( HR=7.08, 95% CI: 1.89-26.59, P=0.004), and preoperative SIS 2 score ( HR=4.02, 95% CI: 1.09-14.83, P=0.037) were all independent risk factors affecting the postoperative prognosis of CRC patients undergoing radical surgical resection. The nomogram model built based on the screened variables has high prediction accuracy: the C-index of the nomogram was 0.75. Conclusion:Age>60 years old, TNM stage Ⅲ-Ⅳ, SIS 2 score are all independent risk factors for postoperative prognosis of colorectal cancer. The nomograph model constructed by this method has high prediction accuracy.

Objective: To analyze the genetic characterization of 2B genotype rubella virus strains first isolated in Liaoning province. Methods: Vero/Slam cells were used to isolate rubella viruses from throat swabs. Fragments of the E1 gene (739 nucleotides) were amplified by reverse transcription-polymerase chain reaction (RT-PCR) and the PCR products were sequenced and analyzed. The phylogenetic trees were constructed with rubella 2B genotypes reference strains. Results: RVi/Liaoning.CHN/13.18/1[2B] was isolateded from the case which had a history of international travel and probably imported from abroad. RVi/Liaoning.CHN/13.18/1[2B] was in the same 1ineage with RVs/Edinburgh.GBR/6.12[2B] and RVs/Kawasaki.JPN/17.11/1[2B], but far from the epidemic strains isolated in China in recent years. RVi/Liaoning.CHN/14.18/1[2B] belonged to the same lineage with rubella virus 2B genotype strains isolated in China from 2014 to 2015, and had the highest homology with RVi/Chouzhou.Anhui.CHN/17.15/2[2B] and RVi/Shaoyang.Zhejiang. CHN/13.13[2B]. Conclusions It was the first time to isolate the 2B genotype rubella virus in Liaoning province and the strain belonged to different 1ineage.

OBJECTIVETo investigate the role of miR-199a-3p in cardiac fibrosis and the potential target of miR-199a-3p.

METHODSCardiac fibroblasts were isolated from C57BL/6 mice and cultured. The miR-199a-3p mimic and Smad1 siRNA were transiently transfected into the cardiac fibroblasts via liposome. Dual luciferase reporter assay was performed to confirm the interaction between miR-199a-3p and the 3'-UTR of Smad1. The expressions of Smad1 and fibrosis-related genes at the mRNA and protein levels in the cells after miR-199a-3p mimic transfection were determined using RT-qPCR and Western blotting, respectively. The expressions of Smad1, Smad3 and fibrosis-related genes at the protein level in cells transfected with miR-199a-3p mimic and Smad1 siRNA were detected using Western blotting.

RESULTSOver-expression of miR-199a-3p significantly increased the expression of cardiac fibrosis-related genes in cultured mouse cardiac fibroblasts. Dual luciferase reporter assay revealed the interaction of miR-199a-3p with the 3'-UTR of Smad1. The results of RT-qPCR and Western blotting confirmed that miR-199a-3p inhibited Smad1 expression at the post- transcriptional level. Transfection with miR-199a-3p mimic and siRNA-mediated Smad1 silencing consistently activated the Smad3 signaling pathway and enhanced the expressions of cardiac fibrosis-related genes in the cardiac fibroblasts.

CONCLUSIONSAs the target gene of miR-199a-3p, Smad1 mediates the pro-fibrotic effect of miR-199a-3p by activating the Smad3 signaling in cultured mouse cardiac fibroblasts.
