This report described a case of eclampsia complicated by hemolysis, elevated liver enzymes, and low platelet count (HELLP) syndrome with refractory hepatic impairment. The patient presented at 34 +6 weeks' gestation with convulsions and impaired consciousness for over 3 hours, accompanied by severe hypertension [240/120 mmHg (1 mmHg=0.133 kPa)]. Emergency cesarean delivery was performed at a local hospital. On postoperative day 2, the patient was transferred to our institution due to sharp transaminase elevation, hepatic failure, and coagulopathy. Although treated with artificial liver support, anti-infection therapy, and organ protection measures, hepatic parameters showed intermittent rebounds. Subsequent detection of cytomegalovirus in bronchoalveolar lavage fluid and blood prompted targeted antiviral therapy, which significantly improved hepatic injury. Through multidisciplinary management, the patient recovered and was discharged 43 days postpartum. Although multiple artificial liver sessions provided limited hepatic function improvement, this case offers valuable insights for managing refractory hepatic impairment in pregnant women, regardless of whether viral infection represented a primary etiology or secondary complication.

Objective: To investigate the trends in incidence and mortality of lung cancer in Huangpu District, Shanghai Municipality from 2002 to 2019, so as to provide the evidence for formulating lung cancer prevention and control measures. Methods: Data of lung cancer incidence and mortality among residents in Huangpu District from 2002 to 2019 were collected through the Shanghai Cancer Registration and Reporting Management System. The crude incidence and mortality of lung cancer was calculated, and standardized by the data from the Chinese Fifth National Population Census in 2000 (Chinese-standardized rate) and the Segi's world standard population in 1960 (world-standardized rate). The trends in incidence and mortality of lung cancer among residents by age and gender were evaluated using annual percent change (APC). Results: A total of 12 965 cases of lung cancer were reported in Huangpu District from 2002 to 2019, and the crude incidence rate was 80.66/105, the Chinese-standardized incidence rate was 34.54/105, and the world-standardized incidence rate was 31.30/105, all showing upward trends (APC=4.588%, 2.933% and 3.247%, all P<0.05). A total of 10 102 deaths of lung cancer were reported, and the crude mortality rate was 62.30/105, showing an upward trend (APC=0.959%, P<0.05); the Chinese-standardized mortality was 25.93/105, and the world-standardized mortality was 22.05/105, both showing downward trends (APC=-1.282% and -1.263%, both P<0.05). The crude incidence and mortality rates of lung cancer in males were higher than those in females (101.39/105 vs. 60.52/105, 85.45/105 vs. 39.87/105, both P<0.05). The crude incidence and mortality rates of lung cancer showed upward trends with age (both P<0.05), reaching their peaks in the age groups of 80-<85 years (341.37/105) and 85 years or above (355.97/105), respectively. Conclusions The incidence of lung cancer showed an upward trend, while the mortality showed a downward trend in Huangpu District from 2002 to 2019. Elderly men were the high-risk group for lung cancer incidence and mortality.

Objective: To investigate the availability and use of child safety seats among children aged 0-3 years, so as to provide the basis for improving riding safety for children. Methods: Parents of children aged 0-3 years in Huangpu District, Shanghai Municipality, were recruited using the stratified multistage random sampling method from May to July 2024. Demographic information, family travel patterns, the use of child safety seat and related health beliefs were collected using questionnaire surveys. Factors affecting the use of child safety seats were identified using a multivariable logistic regression model. Results: Totally 514 valid questionnaires were recovered, with an effective rate of 96.98%. The respondents included 122 fathers (23.74%) and 392 mothers (76.26%), with a median age of 34.00 (interquartile range, 5.00) years. There were 446 families equipping with child safety seats, accounting for 86.77%; and 169 families using child safety seats, accounting for 32.88%. Multivariable logistic regression analysis showed that the parents who had children aged >1-2 years (OR=0.597, 95%CI: 0.366-0.973), travelled 2-4 times per month (OR=0.359, 95%CI: 0.213-0.607) or once per month or less (OR=0.384, 95%CI: 0.202-0.729), and scored high in perceived barrier (OR=0.634, 95%CI: 0.486-0.827) were less likely to use child safety seats; the parents who had children with local household registration (OR=2.506, 95%CI: 1.356-4.633), travelled 5-<10 km (OR=1.887, 95%CI: 1.148-3.101) or ≥10 km (OR=2.319, 95%CI: 1.355-3.967), always wore seat belts (OR=2.342, 95%CI: 1.212-4.524), scored high in perceived susceptibility (OR=1.392, 95%CI: 1.091-1.778) and self-efficacy (OR=1.413, 95%CI: 1.156-1.727) were more likely to use child safety seats. Conclusions Equipping family cars with child safety seats and using them can prevent and reduce traffic injuries among children aged 0-3 years. It is recommended to strengthen publicity to promote the use of child safety seats.

Objective:To construct a device-related pressure injury prevention program for orthopedic patients based on evidence-based and SSKINS (S: skin, S: surface, K: keep moving, I: incontinence, N: nutrition, S: self-care) clinical management model, and to provide reference for clinical nursing practice.Methods:In June 2023, a research team was set up to retrieve the literature related to device-related pressure injury in orthopedic patients, and the evidence was extracted and screened with reference to the SSKINS clinical management model, and the first draft of the protocol was formulated based on clinical practice.

Long non-coding RNAs (lncRNAs) play an important role in cancer metastasis. Exploring metastasis-associated lncRNAs and developing effective strategy for targeted regulation of lncRNA function in vivo are of utmost importance for the treatment of metastatic cancer, which however remains a big challenge. Herein, we identified a new functional lncRNA (denoted lncBCMA), which could stabilize the expression of eukaryotic translation elongation factor 1A1 (eEF1A1) via antagonizing its ubiquitination to promote triple-negative breast cancer (TNBC) growth and metastasis. Based on this regulatory mechanism, an endosomal pH-responsive nanoparticle (NP) platform was engineered for systemic lncBCMA siRNA (siBCMA) delivery. This NPs-mediated siBCMA delivery could effectively silence lncBCMA expression and promote eEF1A1 ubiquitination, thereby leading to a significant inhibition of TNBC tumor growth and metastasis. These findings show that lncBCMA could be used as a potential biomarker to predict the prognosis of TNBC patients and NPs-mediated lncBCMA silencing could be an effective strategy for metastatic TNBC treatment.

OBJECTIVE: To assess the clinical efficacy and health economic value of non-invasive prenatal testing (NIPT) for the prenatal screening of common fetal chromosomal aneuploidies. METHODS: 10 612 pregnant women from October 2017 to December 2019 presented at the antenatal screening clinic of the General Hospital of Tianjin Medical University were selected as the study subjects. Results of NIPT and invasive prenatal diagnosis and follow-up outcome for the 10 612 pregnant women were retrospectively analyzed and compared. Meanwhile, NIPT data for two periods were analyzed for assessing the health economic value of NIPT as the second- or first-tier screening strategy for the prenatal diagnosis of fetal trisomies 21, 18 and 13. RESULTS: The NIPT was successful in 10 528 (99.72%) subjects, with the sensitivity for fetal trisomies 21, 18 and 13 being 100%, 92.86% and 100%, and the positive predictive value (PPV) being 89.74%, 61.90% and 44.44%, respectively. The PPV of NIPT for sex chromosome aneuploidies was 34.21%. Except for one false negative case of trisomy 18, the negative predictive value for trisomy 21, trisomy 13 and other chromosomal abnormalities were 100%. For pregnant women with high risk by serological screening, advanced maternal age or abnormal ultrasound soft markers, NIPT has yielded a significantly increased high risk ratio. There was no statistical difference in the PPV of NIPT among pregnant women from each subgroup. NIPT would have higher health economic value as a second-tier screening until 2019, while compared to 2015 ~ 2017, its incremental cost-effectiveness ratio as a first-tier screening had declined clearly. CONCLUSION The screening efficacy of NIPT for trisomies 21, 18 and 13 for a mixed population is significantly better than conventional serological screening, but it is relatively low for sex chromosomal abnormalities. NIPT can also be recommended for populations with relatively high risks along with detailed pre- and post-test genetic counselling. From the perspective of health economics, except for open neural tube defects, it is possible for NIPT to replace the conventional serological screening in the future as its cost continues to decrease.

Objective : To analyze the trends in incidence of thyroid cancer in Huangpu District, Shanghai from 2002 to 2017, so as to provide insights into the management of thyroid cancer. Methods : The incidence of thyroid cancer in Shanghai from 2002 to 2017 was collected from the cancer registration system created by Shanghai Center for Disease Control and Prevention. The crude and standardized incidence of thyroid cancer were estimated by year, gender and age groups, and annual change percentage ( APC ) was calculated to analyze the trends in incidence of thyroid cancer. Results : A total of 2 854 new cases of thyroid cancer were reported in Huangpu District from 2002 to 2017, and the crude and standardized incidence rates of thyroid cancer were 19.57/105 and 13.47/105, with APC of 18.15% and 17.93% ( P<0.05 ), respectively. The crude and standardized incidence rates of thyroid cancer were 10.02/105 and 7.06/105 in men, with APC of 19.58% and 19.04% ( P<0.05 ), and were 28.90/105 and 19.95/105 in women, with APC of 17.33% and 16.99% ( P<0.05 ), respectively. The crude incidence of thyroid cancer was higher in women than in men ( P<0.05 ). In addition, there were two peaks in the crude incidence of thyroid cancer in patients at age of 35 to 39 and 60 to 64 years, with crude incidence rates of 28.98/105 and 33.36/105, respectively. Conclusions The incidence of thyroid cancer appeared a tendency towards a rise in Huangpu District from 2002 to 2017, and much attention should be paid to females and patients aged 60 to 64 years.

Objective: To establish and evaluate the pyroptosis model of rat chondrocytes induced by tumor necrosis factor-α(TNF-α). Methods: A two-step enzymatic digestion method was used to obtain rat articular chondrocytes, inverted phase contrast microscope was used to observe the morphological structure of chondrocytes. Toluidine blue staining and type Ⅱ collagen(Col Ⅱ) staining were used to identify chondrocytes. Different mass concentrations of TNF-α(5, 10, 20, 40 ng/ml) were used to establish the pyroptosis model with TNF-α(0 ng/ml) as the control group. Cell viability was detected by CCK-8 method and proteins of pyroptosis signal were detected by Western blot. The levels of IL-1β and IL-18 in cultured supernatants were examined by ELISA kits. The expression of gasdermin D(GSDMD) in chondrocytes was detected by immunofluorescence. Scanning electron microscope was used to observe the morphological changes of chondrocyte. Results: Compared with the control group, the cell viability of rat chondrocytes gradually decreased with the increase of TNF-α concentration and the expression of nucleotide-binding and oligomerization domain-like receptor containing protein 3(NLRP3), caspase-1, GSDMD and Phospho-NF-κB p65(P-p65) proteins increased. Furthermore, TNF-α(20 ng/ml) could up-regulate the expression of matrix metalloproteinase-13(MMP-13), the fluorescence expression of GSDMD and the levels of IL-1β and IL-18 while the expression of Col Ⅱ was distinctly reduced. What′s more, the articular chondrocytes were swollen,and the microstructure was destroyed. Conclusion TNF-α(20 ng/ml) can cause the swelling and death of rat chondrocytes, degradation of cartilage matrix and activation of pyroptosis signaling pathway. The pyroptosis model of rat chondrocytes was successfully established.
