【Objective】 To investigate the physical and neuropsychological development of the offspring born to mothers with gestational diabetes mellitus (GDM) at 2 years of age, and to provide evidence to enhance the physical and neuropsychological development of GDM offspring. 【Methods】 A retrospective analysis was conducted on neonates born in the Department of Obstetrics at Qinzhou Maternal and Child Health Hospital from January 2018 to December 2018 and regularly followed at the outpatient service. The neonates were categorized into two groups based on whether their mothers were diagnosed with GDM during pregnancy: the GDM group (n=243) and the control group (n=362). The general clinical data, follow-up information on physical development and neuropsychological development at 1 year and 2 years of age for all children were collected. Their height, head circumference, body weight, BMI, and Gesell developmental quotients (DQs) at 1 year and 2 years of age for both groups were analyzed. 【Results】 1) There were no significant differences in height, head circumference, body weight, and body mass index (BMI) between the two groups at 1 year and 2 years of age during the follow-up period (P>0.05). 2) At 1 year of age, the GDM group exhibited higher rates of abnormal language development (8.6% vs. 3.3%, χ²=7.854), adaptive behavior(11.4% vs. 5.0%,χ²=8.605), and personal social behavior(8.2% vs. 3.0%, χ²=8.062) compared to the control group (P<0.05), and lower DQs for these Gesell subscales (language development 87.6±7.7 vs. 89.4±9.2, t=2.591; adaptive behavior: 88.4±7.8 vs. 90.5±8.9, t=2.957; personal social behavior: 89.1±7.0 vs. 91.2±7.5, t=3.495, P<0.05). 3) At 2 year of age, the GDM group also showed higher rates of adaptive behavior (8.2% vs. 4.1%, χ²=3.927) and personal social behavior (7.3% vs. 3.0%, χ²=4.093) compared to the control group (P<0.05), and lower DQs for these Gesell subscales (adaptive behavior: 89.5±6.5 vs. 91.9±6.9, t=3.878; personal social behavior: 89.9±7.1 vs. 92.1±6.9, t=3.311, P<0.05). 【Conclusions】 The development of adaptive behavior and personal social behavior in offspring born to mothers with GDM remains delayed. Follow-up for GDM offspring should prioritize achieving a balanced development of adaptive behavior and personal social behavior.

Objective To assess the effectiveness of combining problem-based learning(PBL),team-based learning(TBL),and clinical pathway(CP)in standardized training of periodontology residents.Methods A total of 48 residents who were transferred to the Department of Periodontology at the Fourth Affiliated Hospital of Harbin Medical University from January to October 2023 were ran-domly assigned to either the traditional teaching group or the PBL,TBL,and CP combined teaching group,with 24 participants in each group.The traditional teaching group followed conventional teaching methods,while the PBL,TBL,and CP combined teaching group utilized a combination of these three methods.Prior to completing their rotation,both groups underwent professional assessments as well as surveys on satisfaction with standardized training and self-evaluation.Results The professional examination scores ofcombined teaching group were significantly higher than those of the traditional teaching method group(P＜0.05).Both groups expressed satisfac-tion with standardized training and demonstrated proficiency in diagnosing and treating periodontitis through instruction;no statistically significant difference was observed between them(P＞0.05).However,compared to the traditional teaching group,students in the PBL,TBL,and CP combined teaching group showed significant improvements in doctor-patient communication skills,active informa-tion retrieval abilities,learning interest levels,team discussions,and clinical logical thinking abilities(P＜0.05).Conclusion Im-plementing a combination of PBL,TBL,and CP during standardized training of periodontology residents can enhance students'profes-sional examination scores and self-evaluation results,which promotes educational reform development by providing an objective basis.

Background Liver damage presented in endemic arsenic poisoning is usually serious. Studies have shown that oxidative stress, proteasome beta 5 subunit (PSMB5), regulatory transcription factor EB (TFEB), and lysosomes are associated with liver injury, but their specific links to arsenic-induced liver injury remain unclear. Objective Using a sodium arsenite (NaAsO₂)-induced rat liver injury model established earlier by the research group, the expressions of PSMB5, TFEB, and lysosomal associated membrane protein 1 (LAMP1) in liver tissues were detected. Methods Twenty-four SPF Wistar rats were randomly divided into control group, and low, medium, and high dose groups, with 6 rats in each group, half male and half female. The exposure concentrations were 0, 25, 50, and 100 mg·L⁻¹ NaAsO₂ solutions for 24 weeks. At the end of the experiment, liver was dissected after rats were anesthetized. The levels of alkaline phosphatase (ALP), alanine aminotransferase (ALT), total bile acid (TBA), and catalase (CAT) in liver tissues were detected by chemical colorimetry, and the levels of lipid peroxide (LPO), 4-hydroxynonenal (4-HNE), LAMP1, and cathepsin D (CTSD) in liver tissues were detected by enzyme-linked immunosorbent assay (ELISA); the transcriptional expression levels of PSMB5 and TFEB in liver tissues were detected by real-time fluorescence quantitative PCR (RT-qPCR), and the protein expressions of PSMB5, TFEB, and phosphorylated TFEB (p-TFEB) in liver tissues were detected by immunohistochemistry. Results The results of chemical colorimetry and ELISA showed that compared with the control group, the liver homogenate levels of ALP, TBA, and LAMP1 of each arsenic-exposed group, the ALT and LPO in the medium and high concentration groups, the 4-HNE and CTSD in the high concentration group were increased, while the CAT activity of each arsenic-exposed group was decreased (P<0.05). The results of real-time fluorescence quantitative PCR showed that the transcription levels of PSMB5 and TFEB in the liver tissues of each arsenic-exposed group were decreased compared with those of the control group (P<0.05). The results of immunohistochemistry showed that compared with the control group, the expression of PSMB5 of each arsenic-exposed group were decreased, the expression of TFEB in the medium and high concentration groups was decreased, while the expression of p-TFEB of each arsenic-exposed group was increased (P<0.05). The expression of TFEB protein gradually decreased in the nucleus, while the expression of p-TFEB protein gradually increased in the cytoplasm, but no expression of p-TFEB was found in the nucleus. The results of Pearson correlation analysis showed that PSMB5 in liver tissues was positively correlated with CAT (r=0.818, P＜0.05), and negatively correlated with 4-HNE and p-TFEB (r=−0.582, r=−0.899; P＜0.05); TFEB was negatively correlated with CTSD and LAMP1 (r=−0.457, r=−0.564; P＜0.05); CTSD was positively correlated with ALT and ALP (r=0.529, r=0.485; P＜0.05). Conclusion Long-term exposure to NaAsO₂ can induce oxidative stress, inhibit the expression of PSMB5 and TFEB, promote the accumulation of p-TFEB in the cytoplasm, decrease the nuclear entry of active TFEB, damage the lysosome, and cause liver damage.

Objective:To compare the severity of sepsis caused by severe acute pancreatitis (SAP) and community-acquired pneumonia (CAP), improve the understanding of sepsis caused by different types of inflammatory reaction, and provide basis for clinical evaluation of condition and prognosis.Methods:From November 2018 to October 2020, 42 patients with SAP (SAP induced sepsis group) and 68 patients with CAP (CAP induced sepsis group) were selected from Beijing Shunyi Hospital and Dongzhimen Hospital of Beijing University of Chinese medicine. All patients met the diagnostic criteria of sepsis-3 in 2016. The clinical data were analyzed retrospectively, and the indexes, Acute Physiology and Chronic Health Enquiry (APACHE Ⅱ) score and Sequential Organ Failure Assessment (SOFA) score at different time points between the two groups were compared. The correlation between APACHE Ⅱ score and SOFA score and other indicators was analyzed.Results:(1) The mortality rate of SAP induced sepsis group was significantly lower than that of CAP induced sepsis group (2.38% vs 41.18%, P<0.001). The APACHE Ⅱ score and SOFA score of SAP induced sepsis group on the 1st, 3rd and 7th day of hospitalization were significantly lower than those of CAP induced sepsis group at the same time point (APACHE Ⅱ: 10.55±1.16 vs 18.51±0.69, P<0.001, 8.78±0.79 vs 15.45±1.12, P<0.001, 7.77±0.77 vs 12.98±1.08, P<0.001; SOFA: 3.71±0.53 vs 5.57±0.37, P<0.001, 3.24±0.44 vs 5.21±0.52, P<0.001, 2.87±0.14 vs 5.19±0.55, P<0.001). (2) In SAP-induced sepsis group, APACHE Ⅱ score was correlated with lactic acid(Lac), platelet (PLT), PCO 2, creatinine (Cr), aspartate transaminase (AST) and SOFA score, while SOFA score was correlated with Lac, C-reactive protein (CRP), PLT, PO 2, PCO 2, Cr, AST, alanine aminotransferase (ALT) and APACHE Ⅱ score. In CAP-induced sepsis group, APACHE Ⅱ score was correlated with SOFA score. Conclusions:The combination of APACHE Ⅱ score, SOFA score and different clinical indexes has a good indication for judging the severity and prognosis of sepsis patients with different pathogenesis.

We report a case of suspected fetal congenital glaucoma detected by prenatal ultrasound. The mother had no history of cold, medication, or radiation exposure in the first trimester. Routine prenatal ultrasound at 23 +2 weeks of gestation found a 2.5 mm ventricular septum defect, and the sagittal and transverse diameters of the left and right eyeballs were all greater than the normal range of the same gestational weeks, which were noted at 18.57 mm and 17.26 mm, 18.21 mm and 17.22 mm, respectively. Dynamic observation revealed that the bilateral eyelids were unable to close with cornea being exposed to amniotic fluid. The pregnancy was terminated at 23 +6 weeks and a stillborn female weighing 650 g was delivered two days later. Congenital glaucoma was highly suspected by postnatal ophthalmic examination, accompanied by a deformity of the left thumb. No abnormality was detected on fetal chromosome karyotyping or whole-exon sequencing. When unilateral or bilateral megalophthalmos in the fetus is detected by prenatal ultrasound, congenital glaucoma should be considered.

Objective: To analyze the etiology and epidemiological characteristics of gastroenteritis virus in foodborne diseases from three cities in Shandong. Methods: From January to December 2017, six sentinel hospitals in Jinan, Yantai and Linyi city of Shandong Province were selected as the research sites. Stool samples of 1 397 diarrhea patients were collected, as well as basic information and clinical symptoms. Duplex quantitative RT-PCR was used to detect Norovirus genogroupⅠ (Nov GⅠ) and genogroupⅡ (Nov GⅡ), Sapovirus (SAV) and Human astrovirus (HAstV), respectively, quantitative RT-PCR was used to detect group A Rotavirus (RVA), and quantitative PCR was used to detect Enteric adenovirus (EAdV). The specific gene of the virus were sequenced and typed. It was compared that the gastroenteritis virus rate in cases with different characteristics and the clinical symptoms difference between the virus positive and negative cases. Results: The median age (P₂₅, P₇₅) was 23 (1, 42) , mainly male, 57.48% with 803 cased and children under 5 years old, 36.36% with 508 cases. The positive rate of gastroenteritis virus was 33.93% (474 cases), and that of Jinan, Linyi and Yantai City were 32.03% (147/459), 41.54% (189/455) and 28.57% (138/483), respectively (P<0.001). Nov GⅡ had the highest positive rate, 16.54% (231 cases), which, mainly GⅡ.P16/GⅡ.2 (48.28%, 56/116), peaked in May (24.75%, 50/202) and June (19.59%, 38/194). In patients of gastroenteritis virus positive, 44.51% (211/474) had vomiting symptoms, higher than that of patients of gastroenteritis virus negative (34.13%, 315/923). The difference was statistically significant (P<0.001). Conclusion In Shandong Province, the majority of gastroenteritis patients were male and children under 5 years old. Nov GⅡ possessed highest epidemic intensity, and peaked in spring and summer. Viral gastroenteritis had atypical clinical symptoms.

Objective To explore the effect of umbilical cord mesenchymal stem cells with positive human leukocyte antigen(HLA)-G on inducing the production of regulatory T cells(Treg) in vitro.Methods Umbilical cord mesenchymal stem cells were isolated from umbilical cord of neonates. PEGFP-N1-HLA-G plasmid was transfected into the human umbilical cord mesenchymal stem cells by liposome transfection, as PEGFP-N1-HLA-G group. PEGFP-N1 empty vector plasmid was transfected into the human umbilical cord mesenchymal stem cells, as PEGFP-N1 group. The human umbilical cord mesenchymal stem cells without empty vector under the same conditions were set as blank control group. Markers of the umbilical cord mesenchymal stem cells were detected using flow cytometry. The expression of HLA-G protein in each group of cells was identified by Western Blot. After mixed-culturing with CD4+T cells in peripheral blood of healthy subjects for 24 h and 48 h, the proportion of CD4+CD25+Foxp3+Treg in total T cells of each group was detected by flow cytometry. Results CD45, CD34 and HLA-DR presented negative expression on umbilical cord mesenchymal stem cells, while CD29, CD44 and CD105 presented positive expression. HLA-G protein could be expressed in the PEGFP-N1-HLA-G group, which had statistically significant difference compared with the blank control group and PEGFP-N1 group (both P<0.01). After PEGFP-N1-HLA-G group and CD4+T cells were mixed-cultured for 24 h and 48 h, CD4+CD25+Foxp3+Treg accounted for (15.3±1.9)% and (14.3±2.1)% of the total T cells respectively, both of which presented statistically significant difference compared with the blank control group and PEGFP-N1 group (all P<0.05). Conclusions Umbilical cord mesenchymal stem cells with HLA-G gene modified can effectively induce the production of CD4+CD25+Foxp3+Treg in vitro.
