OBJECTIVE To investigate the effects of imperatorin (IMP-SD) on malignant biological behavior of gastric cancer (GC) cells by regulating zinc finger and BTB domain 7B (ThPOK). METHODS Human GC cells MKN-7 were used as the research object and then divided into control group (no treatment), IMP-SD low-, medium- and high-concentration groups (40, 80 and 160 μmol/L IMP-SD), si-ThPOK and si-NC group [treated with 160 μmol/L IMP-SD and then transfected with ThPOK small interfering RNA (si-ThPOK) or its negative control (si-NC)]. After treatment, cell clone formation, migration and invasion abilities and apoptosis of MKN-7 cells were detected; the killing activity of NK cells, T cells classification, the protein expressions of ThPOK, programmed death-1 (PD-1) and programmed death-ligand 1 (PD-L1) were all determined. RESULTS Compared with the control group, the number of cell clones, migration number, invasion number, and the protein expressions of PD-1 and PD-L1 were decreased or down-regulated significantly in IMP-SD groups, while the cell apoptotic rate, NK cell killing activity, CD4+ T proportion, the ratio of CD4+ T proportion and CD8+ T proportion (CD4+ T/CD8+ T), and the protein expression of ThPOK were increased or up-regulated significantly, in a concentration-dependent manner (P<0.05). Compared with IMP-SD high-concentration group and si-NC group, the number of cell clones, migration number, invasion number, and the protein expressions of PD-1 and PD-L1 were increased or up-regulated significantly in si-ThPOK group, while the cell apoptotic rate, NK cell killing activity, CD4+ T proportion, CD4+ T/CD8+ T, and the protein expression of ThPOK were decreased or down-regulated significantly (P<0.05). CONCLUSIONS IMP-SD may reduce the clonal formation, migration and invasion abilities of GC cells, promote their apoptosis and inhibit their immune escape by promoting ThPOK expression.

Objective To investigate the relationship between combined plasma ferritin and triglyceride (TG) concentrations in early pregnancy and the risk of gestational diabetes mellitus (GDM). Methods A total of 1 000 pregnant women who had antenatal care at the Sixth Hospital of Wuhan from January 2021 to January 2023 were selected as the research subjects. The cut-offs of ferritin and TG were analyzed by using unrestricted cube splines. All participants were divided into 4 groups according to the cut‐off values of ferritin and TG. Associations between combined ferritin and TG concentrations and GDM risk were estimated using multivariable logistic regression models. Results A total of 158 (15.8%) participants were diagnosed with GDM. The ferritin and TG levels in early pregnancy of pregnant women in the GDM group were significantly higher than those in the non-GDM group (P<0.05). After adjusting for potential confounders, the OR for the risk of developing GDM after combining ferritin with TG was 2.35 (1.65, 3.35). Couclusion The increase in plasma ferritin and TG concentrations in early pregnancy is positively correlated with the increased risk of GDM. Pregnant women with high plasma ferritin (˃65.7 ng/mL) and high TG (˃1.9mmoL/L) have the greatest risk of GDM.

OBJECTIVE To investigate the effect mechanism of andrographolide (Andro) on neuropathic pain (NP) in rats. METHODS Rats were randomly separated into sham operation group, model group, Andro low-dose (1 mg/kg), Andro medium-dose (5 mg/kg) and Andro high-dose (10 mg/kg) groups, and sodium ferulic acid (150 mg/kg) group, with 12 rats in each group. Except for sham operation group, other groups used the chronic sciatic nerve compression injury method to induce NP model. After modeling, each group was given relevant dose of Andro intrathecally or sodium ferulate intragastrically. The sham operation group and model group were given a constant volume of normal saline once a day for 14 consecutive days. The mechanical withdrawal threshold (MWT) and thermal withdrawal latency (TWL) of rats were detected in each group after 7 and 14 days of administration. After the last medication, the serum levels of interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), prostaglandin E2 (PGE2), and substance P (SP) in rats were detected in each group, and the pathological morphology of spinal cord tissue was observed. mRNA and protein expressions of ionized calcium binding adaptor molecule-1 (Iba-1), growth arrest specific protein 6 (Gas6), and Axl in spinal cord tissue were determined. RESULTS Compared with model group, MWT and TWL after 7 and 14 days of the administration, the mRNA and protein expressions of Gas6 and Axl after the last medication were all increased significantly in administration groups (P<0.05), while the levels of IL-6, TNF-α, PGE2 and SP, mRNA and protein expressions of Iba-1 were all decreased significantly (P<0.05); pathological injuries such as the disordered arrangement of spinal cord neurons and dilation and congestion of capillaries had been alleviated to varying degrees. Compared with sodium ferulic acid group, there was no statistically significant difference in the above indicators in the Andro high-dose group (P>0.05). CONCLUSIONS Andro may inhibit inflammatory response by activating the Gas6/Axl signaling axis, thereby alleviating NP.

Background Dibutyl phthalate (DBP) is one of the most commonly used plasticizers, and has been found to relate to allergic asthma. However, mechanisms behind the phenomenon linking DBP and allergic asthma are still not well comprehended. Objective To investigate the role of endoplasmic reticulum stress in DBP-exacerbated allergic asthma. Methods Thirty-two male mice were divided into four groups at random, eight mice in each group: control group, allergic asthma model group (ovalbumin, OVA), OVA+40 mg·kg−1 DBP exposure group (OVA+DBP), and OVA+40 mg·kg−1 DBP+50 mg·kg−1 4-phenyl butyric acid (4-PBA) group (OVA+DBP+4-PBA). The control group mice were treated with saline via intraperitoneal injection on day 21, 35, 42, and 49, and atomized saline for 30 min per day from day 54 to 60. The OVA group mice were injected with 0.3 mL OVA sensitizing solution via intraperitoneal injection on day 21, 35, 42, and 49, and atomized with 1% OVA solution from day 54 to 60. The OVA+DBP group was treated in the same way as the OVA group to build an allergic asthma model, and was orally exposed to 40 mg·kg−1 DBP from day 1 to 53, plus atomized with 1% OVA solution from day 54 to 60. In order to verify the role of endoplasmic reticulum stress in DBP-exacerbated allergic asthma, 4-PBA was injected intraperitoneally every 2 d from day 1 to 53 in the OVA+DBP+4-PBA group mice. The pathological changes such as airway remodeling, inflammatory cell infiltration, and airway mucous hyperplasia in lung tissues were observed after hematoxylin-eosin (HE) and periodic acid-Schiff (PAS) staining. The contents of total immunoglobulin E (T-IgE) and ovalbumin immunoglobulin E (OVA-IgE) levels in serum, and interleukin (IL)-4, IL-5, IL-13, and IL-17A in alveolar lavage fluid (BALF) were detected by Enzyme-Linked ImmunoSorbent Assay(ELISA). The expression levels of endoplasmic reticulum stress-related proteins including inositol-requiring enzyme 1α (IRE1α), protein kinase R-like endoplasmic reticulum kinase (PERK), and activating transcription factor 6 (ATF6) were detected by immunohistochemistry. Results Compared to the control mice, the OVA mice showed significant asthma-like symptoms, including inflammatory cell infiltration, increased inflammatory cytokines, airway remodeling, and mucous hyperplasia. Compared to the OVA group, long-term exposure to DBP aggravated airway pathological changes in the OVA+DBP mice, and increased the serum T-IgE and OVA-IgE levels (P<0.01), the Th2 (IL-4, IL-5, IL-13) and Th17 (IL-17A) cytokines in BALF (P<0.01), and the expression levels of endoplasmic reticulum stress-related proteins IRE1α, PERK and ATF-6 (P<0.01). In addition, after the 4-PBA treatment, it was found that compared with the OVA+DBP group, the expression levels of endoplasmic reticulum stress-related proteins (IRE1α, PERK and ATF-6) were down-regulated in the OVA+DBP+4-PBA group (P<0.01), the levels of cytokines (IL-4, IL-5, IL-13, and IL-17A) in BALF and T-IgE and OVA-IgE in serum were decreased (P<0.01), and airway remodeling and mucous hyperplasia were significantly alleviated. Conclusion Long-term exposure to DBP could aggravate allergic asthma by activating the endoplasmic reticulum stress pathway. This worsening effect is accompanied by the increase of immunoglobulin IgE levels and the release of Th2 and Th17 cytokines, which in turn leads to lung histopathological changes that affect lung function.

AIM: To investigate the expression levels and clinical significance of hypoxia-inducible factor-1α(HIF-1α)and interleukin-17(IL-17)in conjunctival epithelial cells and tear fluid of patients with dry eyes.METHODS: Retrospective study. A total of 183 dry eye patients admitted to our hospital from February 2021 to March 2023 were selected, and 181 people who were physically healthy in our hospital during the same period were chosen as the control group. HIF-1α and IL-17 expression levels in conjunctival epithelial cells and tear fluid of the two groups of subjects were tested, and the diagnostic value of HIF-1α and IL-17 in conjunctival epithelial cells and tear fluid of the subjects in testing dry eyes was analyzed through receiver operating characteristics(ROC)curves.RESULTS: Compared with the control group, patients in the dry eye group had elevated levels of HIF-1α and IL-17 expression in conjunctival epithelial cells(all P<0.01); and HIF-1α and IL-17 expression increased in tear fluid(all P<0.01). Pearson correlation analysis showed that HIF-1α and IL-17 in the conjunctival epithelium and tear fluid of dry eye patients were negatively correlated with BUT and Schirmer I test(SⅠt), and positively correlated with corneal fluorescein staining scores(all P<0.05); expression levels of HIF-1α and IL-17 in conjunctival epithelial cells and tear fluid of dry eye patients showed positive correlation(all P<0.001). The area under the ROC curve showed that the AUC for the combined diagnosis of HIF-1α and IL-17 in conjunctival epithelium was significantly greater than the AUC for HIF-1α alone in conjunctival epithelium(Z=5.574, P<0.001). The AUC of IL-17 alone in conjunctival epithelial cells(Z=4.351, P<0.001)and the AUC of the combined HIF-1α, IL-17 in tear fluid were significantly greater than the AUC of HIF-1α alone(Z=3.583, P<0.001)and the AUC of IL-17 alone(Z=4.303, P<0.001).CONCLUSION: Conjunctival epithelial cells and tear fluid of dry eye patients have elevated expression levels of HIF-1α and IL-17, and joint detection of HIF-1α and IL-17 expression levels is of great value in the diagnosis of dry eye.

Objective To analyze the characteristics of imported malaria epidemic from overseas in Wuhan, to explore the management mechanism of on-site cases, and to accumulate experience for the treatment of imported malaria in large cities after malaria elimination. Methods The epidemiological data on imported malaria from abroad during the period of malaria elimination (2010-2019) in Wuhan were collected. The gender, age and severe illness-related factors of the cases were analyzed. Based on the characteristics of the epidemic and the current situation of prevention and control, the content and experience of the “Municipal-District 24-7” case mechanism were discussed. Results The medical resources in Wuhan were the best in the central region, resulting in a large number of imported malaria cases, with a total of 474 cases reported from 2010 to 2019 (40.79% of the total number of cases in Hubei Province), including 359 cases of falciparum malaria, 36 severe cases and one death (the death rate was 0.28%). The patients were mainly young and middle-aged men aged 20 to 49 years old (97.26%). There were many referral cases (40.30%), and there was no seasonal clustering of cases reported. The undiagnosed proportion at the first visit was 44.85%, and the time of attack-diagnosis was 4 days or more in 61.00% of cases. The occurrence of severe cases was related to unconfirmed diagnosis at the first visit (χ2=35.46, P<0.001) and attack-diagnosis time (Z=-6.49, P<0.001). Conclusion Imported malaria occurs frequently in Wuhan, mainly falciparum malaria. However, “Municipal-District 24-7” case mechanism has effectively curbed the occurrence of severe and death cases and provided valuable experience for case management in similar cities in China.

OBJECTIVE:
To analyze the clinical effects of CCLG-AML-2015 protocol on newly diagnosed children with acute myeloid leukemia (AML).
METHODS:
The clinical data of 60 newly diagnosed AML children in the Department of Hematology and Oncology, Wuhan Children's Hospital from August 2015 to September 2019 were summarized, the effect of chemotherapy using the CCLG-AML-2015 regimen (hereinafter referred to as the 2015 regimen) were retrospectively analyzed. 42 children with AML treated by the AML-2006 regimen (hereinafter referred to as the 2006 regimen) from February 2010 to July 2015 were used as control group.
RESULTS:
There were no statistical differences between the 2015 regimen group and the 2006 regimen group in sex, age at first diagnosis, and risk stratification (P>0.05). The complete remission rate of bone marrow cytology after induction of 1 course of chemotherapy (84.7% vs 73.1%, P=0.155), and minimal residual disease detection (MRD) negative (42.3% vs 41.4%, P=0.928) in the 2015 regimen group were not statistically different than those in the 2006 regimen group. The bone marrow cytology CR (98.1% vs 80.6%, P=0.004) and MRD negative (83.3% vs 52.8%, P=0.002) in the 2015 regimen group after 2 courses of induction were higher than those in the 2006 regimen group. The 5-year overall survival (OS) rate in the 2015 regimen group (62.3%±6.4% vs 20.6%±6.4%, P=0.001), the 5-year disease-free survival (EFS) rate (61.0%±6.4% vs 21.0% ±6.4% , P=0.001) were better than those in the 2006 regimen group. The 5-year OS and EFS of high-risk transplant patients in the 2015 regimen group were significantly better than those of high-risk non-transplant patients (OS: 86.6%±9.0% vs 26.7%±11.4%, P=0.000; EFS: 86.6%±9% vs 26.7%±11.4%, P=0.000).
CONCLUSION
The 2015 regimen can increase the CR rate after 2 courses of induction compared with the 2006 regimen. High-risk children receiving hematopoietic stem cell transplantation can significantly improve the prognosis.

Dental Caries is a kind of chronic oral disease that greatly threaten human being's health. Though dentists and researchers struggled for decades to combat this oral disease, the incidence and prevalence of dental caries remain quite high. Therefore, improving the disease management is a key issue for the whole population and life cycle management of dental caries. So clinical difficulty assessment system of caries prevention and management is established based on dental caries diagnosis and classification. Dentists should perform oral examination and establish dental records at each visit. When treatment plan is made on the base of caries risk assessment and carious lesion activity, we need to work out patient‑centered and personalized treatment planning to regain oral microecological balance, to control caries progression and to restore the structure and function of the carious teeth. And the follow-up visits are made based on personalized caries management. This expert consensus mainly discusses caries risk assessment, caries treatment difficulty assessment and dental caries treatment plan, which are the most important parts of caries management in the whole life cycle.

OBJECTIVE:
To investigate the efficacy and safety of VDZ (Vedolizumab) in the salvage treatment of glucocorticoid resistance to gastrointestinal graft-versus-host disease (GR-GI GVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) in children.
METHODS:
The clinical data of 5 patients with refractory GI GVHD who received allo-HSCT in Wuhan Children's Hospital from December 2020 to December 2021 were retrospectively analyzed with VDZ salvage therapy.
RESULTS:
Among the 5 children with refractory GI GVHD, there were 1 male and 4 female, including 2 cases of extremely severe aplastic anemia, 1 case of acute myeloid leukemia (M2, high-risk), 1 case of fanconi anemia and 1 case of myelodysplastic syndrome. The median age of transplant recipients was 54.4 (12-164) months. The median treatment time from transplantation to VDZ was 1.4 (0.6-6.8) months. On average, 3.5 (2-5) doses of VDZ were received. After receiving treatment, 2 patients achieved a complete response (CR), 2 patients achieved a very good partial response (VGPR), 1 patient was non-responsive (NR) after a short-term partial response (PR). Compared with that before VDZ treatment, the amount of diarrhea, stool color, blood and traits of the children after medication were effectively improved. The median follow-up time was 9.3 (7.23-12.83) months. No disseminated or severe bacterial/fungal infections occurred during VDZ treatment and follow-up, and 2 children died of leukemia recurrence and pulmonary bronchiolitis obliterans.
CONCLUSION
VDZ salvage treatment of refractory GI GVHD in children has obvious short-term efficacy and good safety.
