Objective:To analyze the changes of peripheral perfusion index (PPI) with late-onset sepsis (LOS) in very low birth weight infants during hospitalization.Methods:Very low birth weight infants admitted to the neonatal intensive care unit of Children′s Hospital of Fudan University from August 1, 2021 to August 31, 2022 were consecutively included.Infants with admission age ≥three days and unstable circulation, or positive blood culture within three days after birth were excluded.From the day of admission, the PPI values of the right hand and either foot of the infants were measured with Masimo SET Radical-7 everyday while whether LOS occurred during hospitalization was observed.The mean PPI curve of very and extremely low birth weight infants without LOS was plotted.For those with LOS confirmed by blood culture, the PPI change trajectory three days before and after the occurrence of LOS was drawn, and the change trend of PPI before the occurrence of LOS was analyzed by trend chi-square test.Non-parametric test was used to analyze the effect of LOS on pre- and post-ductal PPI values.Results:A total of 107 very low birth weight infants were included in the final analysis.Among them, there were 11 infants confirmed as LOS by blood culture, 37 infants diagnosed as clinical LOS, and 59 infants without LOS.Pre-and post-ductal PPI values of very low birth weight infants without LOS were 2.06±1.30 and 1.72±0.92, respectively; those with clinical LOS were 1.90±0.94 and 1.58±0.83, respectively; those with LOS confirmed by blood culture were 1.92±1.11 and 1.62±0.82, respectively.For infants with LOS confirmed by blood culture, the pre-and post-ductal PPI values showed a continuous downward trend during three days before the onset of disease, with the lowest PPI values on the first day before the diagnosis of blood culture.The downtrend of pre-ductal PPI was statistically significant ( χtrend2=5.57, P<0.05). Conclusion:The PPI value of very low birth weight infants show a downward trend when LOS occurs.It should be observed dynamically in clinical practice, which is helpful to suspect or identify LOS as early as possible.

Background: Both type 1 diabetes mellitus (T1DM) and metabolic syndrome (MetS) are associated with an elevated risk of morbidity and mortality yet with increasing heterogeneity. This study primarily aimed to evaluate the prevalence of MetS among adult patients with T1DM in China and investigate its associated risk factors, and relationship with microvascular complications. Methods: We included adult patients who had been enrolled in the Guangdong T1DM Translational Medicine Study conducted from June 2010 to June 2015. MetS was defined according to the updated National Cholesterol Education Program criterion. Logistic regression models were used to estimate the odds ratio (OR) for the association between MetS and the risk of diabetic kidney disease (DKD) and diabetic retinopathy (DR). Results: Among the 569 eligible patients enrolled, the prevalence of MetS was 15.1%. While female gender, longer diabetes duration, higher body mass index, and glycosylated hemoglobin A1c (HbA1c) were risk factors associated with MetS (OR, 2.86, 1.04, 1.14, and 1.23, respectively), received nutrition therapy education was a protective factor (OR, 0.46). After adjustment for gender, age, diabetes duration, HbA1c, socioeconomic and lifestyle variables, MetS status was associated with an increased risk of DKD and DR (OR, 2.14 and 3.72, respectively; both P<0.05). Conclusion Although the prevalence of MetS in adult patients with T1DM in China was relatively low, patients with MetS were more likely to have DKD and DR. A comprehensive management including lifestyle modification might reduce their risk of microvascular complications in adults with T1DM.

The clinical features and genetic variants of the patient with sitosterolemia who was referred to Shanghai Children′s Medical Center, Shanghai Jiaotong University School of Medicine from June 2019 to January 2020 were retrospectively analyzed.The patient was treated with Ezetimibe tablets combined with diet control, and the follow-up was performed regularly.Besides, a relevant literature review was conducted.A 7-year and 5-month-old boy was referred to the hospital for " repeated thrombocytopenia for 7 months" with normal serum cholesterol.The whole exome sequencing showed that compound heterozygous mutations (p.Arg446*, p.Gln251*) in ABCG5 gene were inherited from their parents respectively.Hence, he was diagnosed with sitosterolemia.After 29 days of treatment with Ezetimibe tablets combined with diet control, the patient′s platelets returned to normal values without obvious adverse reactions related to drugs.Children with sitosterolemia may present with rare thrombocytopenia, and the therapeutic effects of Ezetimibe tablets combined with diet control are favorable.

Objective To understand the current situation of patients with advanced schistosomiasis in Suzhou, and to provide a basis for scientific management, medical assistance, and improvement of patients' quality of life. Methods Questionnaire survey, physical examination and B-ultrasound examination were performed on the registered patients with advanced schistosomiasis. The diagnosis and classification were carried out according to the “Schistosomiasis Control Manual”. The epidemiological and clinical characteristics, disease classification, and medical and financial assistance of all existing patients were analyzed. Results There were 2 420 cases of advanced schistosomiasis in Suzhou. Their distribution was highly correlated with the cumulative area of oncomelania snails and the cumulative number of schistosomiasis patients in each district (county) (r=0.949, P<0.01; r=0.946, P<0.01). There were 845 males and 1 575 females. The highest proportion of male patients was found in Suzhou Industrial Park and the lowest in Kunshan (χ²=26.591, P<0.001). The average age of patients was (76.80±7.55) years old, and the age of female patients were higher that of male patients (F=72.01, P<0.001). The splenomegaly type was the most common (2 165), ascites type was the second (198), colonic proliferative type was the third (55), and pygmy type was the least (2). A total of 895 patients were cured and 1 337 patients were improved, while 188 patients were not cured. The condition of advanced schistosomiasis patients with different clinical types was different (χ² =226.034, P<0.001), and the condition of patients with ascites was the worst. 1 438 patients' labor level was reduced, and 540 patients lost their labor ability, while only 442 patients were normal. Age increase (β=0.012，P<0.001), clinical classification being ascites type (β=0.346，P<0.001) and need for treatment (β=0.298，P<0.001) were risk factors for the loss of labor ability in patients with late schistosomiasis. The stable condition of the disease (β= -0.089，P=0.001) was a protective factor. Conclusion There are a large number of advanced schistosomiasis cases in Suzhou, and the epidemiological characteristics of advanced schistosomiasis patients in different districts (cities) are different. The relief work of advanced schistosomiasis in Suzhou should focus on the historical heavy epidemic areas, strengthen the nursing care of the elderly patients, and pay attention to the quality of life of patients with ascites. It is also important to strengthen the follow-up nursing of patients with splenomegaly to avoid turning into ascites. All districts and counties should be guided by the characteristics of local patients and formulate targeted scientific management methods and rescue policies to improve the quality of life of patients.

Objective: This study examined school-based sexual harassment experience among college students in Guangzhou, and to provide theoretical basis for preventing campus sexual harassment. Methods: A cross-sectional survey was conducted among 1 062 college students from five universities in Guangzhou, China. A self-made questionnaire regarding awareness sexual harassment and experience of school-based sexual harassment was filled out by students voluntarily and anonymously. Results: A total of 169 students reported they experienced school-based sexual harassment. The incidence of school-based sexual harassment among college students in Guangzhou was 15.91%, higher among female students (20.30%) than male students(10.2%)(χ 2=19.91, P<0.01). Verbal harassment (10.26%) was the most common type of sexual harassment, followed by physical harassment (7.16%), visual harassment (4.61%) and unwanted sexual advances (1.69%). Sexual harassment primarily took place in teaching building(58), dormitory(33) and office(17). Among the victims, 116(68.64%) were influenced by harassment. Females(n=94) being harassed were more likely to be negatively influenced compare to males(n=22). Conclusion School-based sexual harassment may result adverse psychological outcomes to students, more emphasis should be put on the prevention of sexual harassment.

BACKGROUND:Various surface modification techniques have been used to improve the bioactivity of titaniumimplant in vivo. OBJECTIVE:To investigate the effects of enamel matrix proteins (EMPs) on the growth of apatite coatings on dual thermo-etching treated pure titanium. METHODS:EMPs were extracted from porcine tooth germs and then were identified. Dual thermo-etching was applied to treat titanium samples fol owing polished, and then immersed in a blank simulated body fluid supersaturated calcification solution (control group) or supersaturated calcification solution containing different concentrations of EMPs for 7 days. The morphology of samples was observed using scanning electron microscope, and element components and crystal structures of the apatite coatings were analyzed by energy dispersive spectrometer and X-ray diffraction. RESULTS AND METHODS:After double-etching, a pit-like rough surface was observed on the titanium plate. After 7-day mineralization, in the control group, no overt calcium-phosphate deposits were found on the titanium surface;however, in the experimental groups, there were calcium-phosphate deposits, whose quantity and morphology changed with increasing concentrations. Energy dispersive spectrometer showed that the main element components of the mineralized coating included calcium, phosphorus, oxygen and carbon, and the calcium-phosphate ratio ranged from 1.32 to 1.41. The apatite coatings were proved to be carbonate hydroxyapatite by X-ray diffraction. To conclude, EMPs promote apatited deposition on pure titanium surfaces in a concentration-dependent manner.
