To investigate the malignant progression and molecular mechanism of KHSRP regulating esophageal squamous cell carcinoma(ESCC) through the JAK1/STAT3 signaling axis. Tumor tissues and adjacent non-tumor tissues were collected from 72 patients with ESCC. Human normal esophageal epithelial cells(Het-1A) and multiple ESCC cell lines(EC-9706, TE-7, KYS-450, FLO-1, SK-GT-4, BE-3) were cultured. The expression level of KHSRP in the cells was detected using real-time fluorescence quantitative polymerase chain reaction(RT-qPCR). Through lentiviral transfection technology, stable KHSRP-knockdown EC-9706 and SK-GT-4 cell models(sh-KHSRP group), as well as stable KHSRP-overexpressing BE-3 and KYS-450 cell models(KHSRP group), were established, and corresponding negative control groups(sh-NC group and Vector group) were also established. Cell proliferation, migration, and invasion abilities were assessed using the cell counting kit-8(CCK-8) assay, Transwell migration assay, and Transwell invasion assay, respectively. A total of 62 male BALB/C nude mice aged 4 to 6 weeks were selected for the experiments. Thirty-two nude mice with subcutaneous tumor-loading experiments were randomly divided into four groups: sh-KHSRP 1 group, sh-NC 1 group, KHSRP 1 group, and Vector 1 group, with 8 mice in each group. Thirty nude mice with tail vein injection for lung metastasis model experiments were randomly divided into four groups: sh-KHSRP 2 group( The results of RT-qPCR revealed that, compared with human normal esophageal epithelial cells, the expression of KHSRP was significantly elevated in ESCC cell lines(EC-9706, TE-7, KYS-450, FLO-1, SK-GT-4, BE-3)( KHSRP is upregulated in ESCC and can positively regulate the JAK1/STAT3 signaling axis, potentially promoting the malignant progression of metastasis in ESCC.

Objective To investigate the capillarization of liver sinusoidal endothelial cells (LSECs) and its association with hepatic fibrosis during the development of alveolar echinococcosis, so as to provide the basis for unraveling the mechanisms underlying the role of LSEC in the development and prognosis of hepatic injuries and hepatic fibrosis caused by alveolar echinococcosis. Methods Forty C57BL/6 mice at ages of 6 to 8 weeks were randomly divided into a control group and 1-, 2- and 4-week infection groups, of 10 mice in each group. Each mouse in the infection groups was intraperitoneally injected with 2 000 Echinococcus multilocularis protoscoleces, while each mouse in the control group was given an equal volume of phosphate-buffered saline using the same method. All mice were sacrificed 1, 2 and 4 weeks post-infection and mouse livers were collected. The pathological changes of livers were observed using hematoxylin-eosin (HE) staining, and hepatic fibrosis was evaluated through semi-quantitative analysis of Masson’s trichrome staining-positive areas. The activation of hepatic stellate cells (HSCs) and extracellular matrix (ECM) deposition were examined using immunohistochemical staining of α-smooth muscle actin (α-SMA) and collagen type I alpha 1 (COL1A1), and the fenestrations on the surface of LSECs were observed using scanning electron microscopy. Primary LSECs were isolated from mouse livers, and the mRNA expression of LSEC marker genes Stabilin-1, Stabilin-2, Ehd3, CD209b, GATA4 and Maf was quantified using real-time fluorescence quantitative PCR (qPCR) assay. Results Destruction of local liver lobular structure was observed in mice 2 weeks post-infection with E. multilocularis protoscoleces, and hydatid cysts, which were surrounded by granulomatous tissues, were found in mouse livers 4 weeks post-infection. Semi-quantitative analysis of Masson’s trichrome staining showed a significant difference in the proportion of collagen fiber contents in mouse livers among the four groups (F = 26.060, P < 0.001), and a higher proportion of collagen fiber contents was detected in mouse livers in the 4-week infection group [(11.29 ± 2.58)%] than in the control group (P < 0.001). Immunohistochemical staining revealed activation of a few HSCs and ECM deposition in mouse livers 1 and 2 weeks post-infection, and abundant brown-yellow stained α-SMA and COL1A1 were deposited in the lesion areas in mouse livers 4 weeks post-infection, which spread to surrounding tissues. Semi-quantitative analysis revealed significant differences in α-SMA (F = 7.667, P < 0.05) and COL1A1 expression (F = 6.530, P < 0.05) in mouse levers among the four groups, with higher α-SMA [(7.13 ± 3.68)%] and COL1A1 expression [(13.18 ± 7.20)%] quantified in mouse livers in the 4-week infection group than in the control group (both P values < 0.05). Scanning electron microscopy revealed significant differences in the fenestration frequency (F = 37.730, P < 0.001) and porosity (F = 16.010, P < 0.001) on the surface of mouse LSECs among the four groups, and reduced fenestration frequency and porosity were observed in the 1-[(1.22 ± 0.48)/μm2 and [(3.05 ± 0.91)%] and 2-week infection groups [(3.47 ± 0.10)/μm2 and (7.57 ± 0.23)%] groups than in the control group (all P values < 0.001). There was a significant difference in the average fenestration diameter on the surface of mouse LSECs among the four groups (F = 15.330, P < 0.001), and larger average fenestration diameters were measured in the 1-[(180.80 ± 16.42) nm] and 2-week infection groups [(161.70 ± 3.85) nm] than in the control group (both P values < 0.05). In addition, there were significant differences among the four groups in terms of Stabilin-1 (F = 153.100, P < 0.001), Stabilin-2 (F = 57.010, P < 0.001), Ehd3 (F = 31.700, P < 0.001), CD209b (F = 177.400, P < 0.001), GATA4 (F = 17.740, P < 0.001), and Maf mRNA expression (F = 72.710, P < 0.001), and reduced mRNA expression of Stabilin-1, Stabilin-2, Ehd3, CD209b, GATA4 and Maf genes was quantified in three infection groups than in the control group (all P values < 0.001). Conclusions E. multilocularis infections may induce capillarization of LSECs in mice, and result in a reduction in the expression of functional and phenotypic marker genes of LSECs, and capillarization of LSECs occurs earlier than activation of HSC and development of hepatic fibrosis.

Objective:To depict the long-term trends of prevalence and disease burden of preterm birth from 1990 to 2019.Methods:Data was from the 2019 Global Burden of Disease study. The prevalence rate (%) and disability adjusted life years (DALYs) rate of preterm birth were adopted and were further stratified by sex. China's prevalence rate and DALYs rate were compared with those of high-income, middle and high-income, middle and low-income, and low-income countries, defined by the World Bank. Joinpoint log-linear regression model was used to analyze the trend.Results:In 2019, the prevalence of preterm birth in China was 6.34% [95% uncertainty interval ( UI): 6.23%-6.44%], lower than the global average level (11.24%,95% UI: 11.16%-11.32%) or the average level of low-income (13.15%, 95% UI: 12.97%-13.33%), lower-middle income (12.53%, 95% UI: 12.39%-12.68%), upper-middle income (8.22%, 95% UI: 8.15%-8.29%) and high-income (8.75%, 95% UI: 8.67%-8.84%) countries. The DALYs rate (person-year /100 000) of preterm birth in China was 217.12 (95% UI: 191.30-246.69), lower than the average level of the world (886.81, 95% UI: 762.12-1 034.49), low-income (1 905.24, 95% UI: 1 542.35-2 377.54), lower-middle-income (1 349.98, 95% UI: 1 154.04-1 583.81) and upper-middle-income (366.56, 95% UI: 321.51-416.88) countries, but higher than the average level of high-income countries (206.21,95% UI: 179.96-234.90). From 1990 to 2019, the prevalence and DALYs rate of preterm birth in China showed a downward trend, with an average annual decline of 0.56% (95% CI:0.54%-0.58%) and 5.87% (95% CI:5.54%-6.19%), respectively. In general, the prevalence rate of preterm birth in men declined faster than that in women (men:0.64%, 95% CI: 0.62%-0.66%; women: 0.46%, 95% CI: 0.44%-0.48%), so as the DALYs rate (men:5.90%, 95% CI: 5.56%-6.24%; women:5.81%,95% CI: 5.50%-6.13%). Conclusions:From 1990 to 2019, the prevalence and DALYs rate of preterm birth in China showed an overall downward trend, and the decline rate was higher in men than in women. The etiological research on the risk factors of preterm birth, especially spontaneous preterm birth, should be further pursued, and a more comprehensive and precise monitoring, prevention, and health care system for preterm birth needs to be formulated.

Bacterial infection is the main cause of infectious diseases in children. Antibacterials play an important role in anti infection treatment of children. At present, the treatment of antimicrobial drugs in children is facing a severe situation of bacterial resistance. In January 2020, a children′s specialized hospital carried out the practice of precise management of antibiotics in combination with key performance indicators. Through the multi sectoral linkage of management and technology, eight key performance indicators and assessment methods were set up from three levels of antibiotic use, bacterial resistance and hospital infection, to standardize the clinical application of antibiotics and continue to promote the rational use of antibiotics. This practice had improved the performance indicators of antibacterial management. Among them, the use intensity of antibacterial drugs for inpatients decreased from 40.07 DDD in 2019 to 29.00 DDD in 2021, the use rate of antibacterial drugs for inpatients decreased from 81.32% to 64.40%, the percentage of antibacterial drug expenses in total drug expenses decreased from 35.41% to 26.82%, the use proportion of non restricted antibacterial drugs in antibacterial drugs increased from 71.30% to 82.21%, and the drug resistance rate of Salmonella to β-Lactam/enzyme inhibitors decreased from 4.84% to 0.03%, and the incidence of hospital infection decreased from 1.16% to 0.96%. The precise management of antibiotics in combination with key performance indicators improved the level of rational use of antibiotics, effectively curbed bacterial resistance, achieved phased results, so as to provide a reference for the scientific management of antibiotics in children′s hospitals.

Burning mouth syndrome (BMS) is a common clinical disorder characterized by burning of the mouth or other discomfort, which significantly affects the quality of life of patients. The present article introduces and makes comparison of the mechanisms and clinical treatments of BMS in modern stomatology and traditional Chinese medicine. Modern stomatology studies have shown that BMS is related to the factors of neuropathy, psychology, endocrine or metabolic disorders, drug effects and local adverse stimuli. Traditional Chinese medicine suggests that BMS is mainly caused by diet, fatigue, bad emotion, poor health, oldness, etc. Individualized therapy is advocated in the treatment of BMS. Modern stomatology pays attention to comprehensive treatment for psychological disorder, systematic and oral local diseases. The thoughts of dialectical therapy and health keeping in traditional Chinese medicine also have clinical value.

Objective To study the protective effect of chlorogenic acid(CGA)on the apoptosis of PC12 cells induced byβ-amyloid protein23-35(Aβ25-35)and its mechanism. Methods The cells model of death was estab-lished by Aβ25-35 (20 μmol/L)-induced PC12 cells. The cells were interfered with 5 different concentrations of CGA. CCK-8 assay was used to detect cells viability to determine the 3 concentrations of CGA in future experi-ments. The cells were divided randomly into control group ,model group and interference groups with 3 different concentrations of CGA. Cells apoptosis rates were detected by flow cytometry;colorimetry method was used to detect MDA,SOD and GSH-Px. The mitochondrial membrane potential(MMP)was detected by fluorescent staining and the expression of caspase-3 by western blot. Results Compared with model group,the cells viability of CGA groups were increased but the apoptosis rates were reduced;the activity of SOD and GSH-Px were increased but the level of MDA,MMP and caspase-3 were decreased(P<0.05). Conclusions CGA has a protective effect on Aβ25-35-induced PC12 cells apoptosis and it may be related to the improvement of cellular antioxidation capacity and mitochondrial damage.

Objective To study the CT and MR characteristic features of the respiratory epithelial adenomatoid hamartoma of olfactory clefts. Methods (1)The CT and MRI findings of 29 patients with histologically proved respiratory epithelial adenomatoid hamartoma in the olfactory clefts were retrospectively reviewed.All patients underwent CT and 8 of them underwent MRI. Location, CT and MRI features, and associated findings of the disease were reviewed;(2)The CT findings, olfactory clefts width, total nasal distance, and the ratio of OC to the total nasal distance of the case patients (29 cases) and the control patients (33 patients with sinusitis) were compared to investigate the correlation of the olfactory clefts distance and the incidence of respiratory epithelial adenomatoid hamartoma in olfactory clefts. Results All patients were associated with sinusitis, and 23 had sinonasal polyps, 1 had papilloma. On nonenhanced CT, the OC lesions with the OC widening were isodense to gray matter in all cases, and the lesions caused the adjacent bony expansion and absorption rather than erosion; 15 cases were bilateral diseases and 14 were unilateral;The olfactory clefts width of the case patients and the control patients were (1.03±0.24) cm, (0.71± 0.17) cm, respectively. There was statistically significant difference (t=4.963, P<0.01) for the olfactory clefts width between the case patients and the control patients, and there was no significant difference (t=1.640, P>0.05) for the total nasal distance, and was significant difference(t=6.029,P<0.01)in the ratio of OC to the total nasal distance between the two groups. On T1WI, the disease appeared isointense in 6 patients and slightly hypointense in 2 patients compared with gray matter. On T2WI, the lesions revealed heterogeneous isointense in all patients. Regular cribriform pattern was found on MR T2WI and enhanced TlWI. Conclusions The unilateral or bilateral olfactory cleft opacification in chronic sinusitis patients with or without sinonasal polyposis, with involved OC widening and the adjacent bony walls compressed and remodeled may highly suggests the presence of REAH in the OC. The lesions showed inhomogeneous isointense signal on T2WI images, regular cribriform pattern enhancement are typical imaging feature of this entity.
