Background Obstructive sleep apnea (OSA) is a sleep disorder characterized by recurrent episodes of obstruction of the upper airway during sleep. Given the substantial number of OSA patients, it is urgently in need to address the burden on society. Current available evidence linking outdoor light at night (LAN) to OSA is scarce. Objective To explore the relationships regarding outdoor LAN and OSA among residents in Southern China. Methods A total of 3925 hospitalized patients in Guangdong Provincial People's Hospital Sleep Center were recruited between January 1, 2005 and December 31, 2015. The severity of OSA was determined by apnea-hypopnea index (AHI) using polysomnography or home sleep test. The annual Suomi National Polar-orbiting Partnership Visible Infrared Imaging Radiometer Suite (NPP-VIIRS)-like LAN data with a 500 m spatial resolution were used to evaluate outdoor LAN levels of the participants 1, 3, and 5 years before undergoing sleep monitoring. Generalized linear regression models were utilized to examine the associations of outdoor LAN with OSA. Results The ORs (95%CIs) of OSA, mild OSA, and moderate OSA were 1.175 (1.021, 1.351), 1.215 (1.038, 1.421), and 1.195 (1.003, 1.425) respectively for per interquartile range (IQR) increment in three-year average outdoor LAN. The results of stratified analyses showed a higher OR of 1.933 (95%CI: 1.424, 2.637) in female than male participants (P _interaction < 0.001). Additionally, the ORs of OSA did not substantially change using one-year/ five-year instead of three-year average outdoor LAN. Conclusion Our findings demonstrate that an elevated outdoor LAN is significantly associated with higher odds of OSA (especially mild and moderate OSA) in Southern China, especially in females. An effective outdoor LAN management and policy-making framework has been suggested as potential preventive measures to reduce burden of OSA.

[Objective] To investigate the factors associated with alanine aminotransferase (ALT) abnormalities in multi-ethnic blood donors across five Zang autonomous prefectures in the plateau regions of Qinghai Province, and to provide evidence for ensuring blood safety and formulating screening strategies. [Methods] A retrospective analysis was performed on the ALT abnormal test results of blood donors in the Zang autonomous prefectures of Qinghai from 2022 to 2024. The correlations between ALT levels and factors including gender, age, altitude, and infectious markers were investigated. [Results] The overall ALT unqualified rate among blood donors in this region was 9.01%. Significant differences in ALT levels were observed across genders and age groups (P<0.05). Variations in ALT abnormality rates were also noted among different plateau regions (P<0.05). Overall, ALT values exhibited an increasing trend with rising altitude. The average ALT unqualified rates were 11.19% in Zang donors, 7.96% in Han donors, and 4.79% in donors from other ethnic groups (P<0.05). No statistically significant association was observed between ALT abnormality and the presence of HBV/HCV infectious markers (P>0.05). [Conclusion] In the plateau areas of Qinghai, multi-ethnic blood donors have a relatively high ALT levels and ALT unqualified rates, showing distinct regional characteristics. ALT elevation in voluntary blood donors is related to non-pathological factors such as gender, age, and dietary habits, but not to infectious indicators.

Objective To investigate the clinical value of fiber nasopharyngoscope applied in adenoid hypertrophy(AH)combined with allergic rhinitis(AR)in children.Methods Clinical data of 174 pediatric patients from January 2021 to March 2024 was collected and analyzed.Among them,129 cases were diagnosed with AH via fiber nasopharyngoscope examination(79 cases with AR were assigned to the AH with AR group,the remaining 50 cases of simple AH without AR were assigned to the AH group),and 45 cases of simple AR without AH through fiber nasopharyngoscope examination were assigned to the AR group.And 25 healthy children who came to our pediatric health department for health examinations during the same period were selected as the healthy control(HC)group.On the day of admission,all subjects underwent lateral X-ray examination of the nasopharynx,and the ratio of the maximum thickness of adenoids to the anterior posterior diameter of the nasopharynx cavity(A/N ratio)was calculated.Meanwhile their of peripheral blood eosinophil(EOS)percentage,serum interleukin-17(IL-17),and tumor necrosis factor-α(TNF-α)levels were tested.The A/N ratio,peripheral blood EOS percentage,serum IL-17 and TNF-α levels were compared among the AH with AR group,AH group,AR group,and HC group.The A/N ratio,peripheral blood EOS percentage,serum IL-17 and TNF-α levels of children with different degrees of adenoid obstruction under fiber nasopharyngoscope were compared in AH and AR group.Spearman correlation coefficient was used to analyze the correlation between the degree of adenoid obstruction under fiber nasopharyngoscope and the levels of peripheral blood EOS percentage,serum IL-17 and TNF-α in children from AH and AR group.Result A/N ratio:the value in AH with AR group was higher than that in AH group(P＜0.05),the value in AH group was higher than that in AR group(P＜0.05),and the value in AR group was higher than that in HC group(P＜0.05).Peripheral blood EOS percentage,serum IL-17 and TNF-α levels:AH with AR group had higher levels than those in AR group(P＜0.05),AR group had higher levels than those in AH group(P＜0.05),and AH group had higher levels than those in HC group(P＜0.05).The A/N ratio,peripheral blood EOS percentage,serum IL-17 and TNF-α levels in children with adenoid obstruction degree Ⅲ～Ⅳ under fiber nasopharyngoscope in the AH group were significantly higher than those in children with degree Ⅰ～Ⅱ(P＜0.05).Spearman correlation analysis showed that the degree of adenoid obstruction under fiber nasopharyngoscope in children with AH accompanied by AR significantly positively correlated with peripheral blood EOS percentage,serum IL-17 and TNF-α levels(r values were 0.527,0.451,and 0.402 respectively,P＜0.05).Conclusion Fiber nasopharyngoscope can be used for the diagnosis of AH with AR in children,and can be positive in determining severity of the patient's condition when combined with peripheral blood EOS percentage,serum IL-17 and TNF-α levels.

Objective:To explore the latent classes of fear of childbirth in late pregnancy women and its relationship with sense of coherence, providing reference for precise support interventions in clinical practice.Methods:From January to September 2023, convenience sampling was used to select 304 pregnant women who underwent antenatal examination at the Obstetrics Clinic of Affiliated Hospital of Hangzhou Normal University as participants. The General Information Questionnaire, Childbirth Attitudes Questionnaire, and the Sense of Coherence Scale-13 (SOC-13) were used for questionnaire survey. Latent profile analysis was used to explore the categories of fear of childbirth in late pregnancy women, and analyzed differences of SOC-13 scores among women with different categories of fear of childbirth.Results:Fear of childbirth in 304 late pregnant women was divided into three latent classes, including low-level fear group of (50.0%, 152/304), moderate-level fear group of (35.2%, 107/304), and high-level fear group of (14.8%, 45/304). ANOVA analysis showed that there were statistically significant differences in total score and dimension scores of SOC-13 among late pregnancy women with three different classes of fear of childbirth ( P<0.05) . Conclusions:There are three latent classes of fear of childbirth in late pregnancy women. The sense of coherence among pregnant women affects their fear of childbirth. Nursing staff should address the heterogeneity of fear of childbirth in late pregnancy women, starting from sense of coherence, and take targeted intervention measures to reduce the fear of childbirth in late pregnancy women.

Objective:To recheck the Histoplasma capsulatum and Coccidioides sp. strains of the past by molecular identification and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry(MALDI-TOF MS). Methods:The phylogenetic relationships among the ten Histoplasma capsulatum isolates and reference strains were analyzed by multilocus sequence typing (MLST). Based on the Coi region, Coccidioides posadasii was distinguished from Coccidioides immitis accurately. MALDI-TOF MS was used to set up the MALDI-TOF MS database of Histoplasma capsulatum and Coccidioides sp. for rapid identification. In addition, hierarchical clustering of spectra was compared with MLST. Results:An unrooted dendrogram constructed with MLST showed that ten individuals of Histoplasma capsulatum were divided into three clades: Eurasia clade, Australia clade and North American class 2 clade, in agreement with the establishment by MALDI-TOF MS cluster analysis. All individuals of Coccidioides sp. were identified as Coccidioides posadasii with Coi region primers. The in-house MALDI-TOF MS database of Histoplasma capsulatum and Coccidioides posadasii was expanded and reached an identified accuracy of 100%. Conclusions:We improve the recognition of Histoplasma capsulatum and Coccidioides posadasii by molecular pathways which shows the major species or clades in Chinese mainland. The in-house MALDI-TOF MS database of Histoplasma capsulatum and Coccidioides posadasii can provide a new efficient way to identify those pathogens rapidly.

For muscle-invasive bladder cancer (MIBC) patients, preoperative neoadjuvant chemotherapy (NAC) can reduce the tumor stage, treat micrometastases, prolong the median survival, and improve the prognosis.However, NAC is associated with side effects such as renal impairment, thromboembolism and drug toxicity.NAC itself suffers from deficiencies such as renal function impairment, thromboembolism, and drug toxicity.Its therapeutic efficacy is affected by factors such as tumor pathology type, DNA repair gene defects, whether it is primary MIBC, and TNM staging, so there are certain limitations in its use.Based on the cisplatin treatment regimen, more and more studies are exploring the limitations and shortcomings of NAC in MIBC treatment regimen.Therefore, this paper provides an overview and outlook of the application of NAC in MIBC treatment.

Objective:To investigate the feasibility, safety and effectiveness of colonic interposition with vascular anastomosis in reconstructing the entire esophagus and hypopharynx after resection of hypopharyngeal cancer with esophageal cancer.Methods:We conducted a retrospective analysis of 4 male patients with simultaneous multiple primary cancers of the hypopharynx and esophagus, aged 47 to 58, treated in the Department of Head and Neck Surgery at the Hunan Cancer Hospital from February to August 2019. All cases underwent total hypopharyngectomy and total esophagectomy, of whom, three cases presented with total laryngectomy and one case with larynx preservation. Colonic interposition was performed using the left colic artery as a pedicle, with an average colonic length of 48.5 cm. The colon was elevated through the esophageal bed to the neck, and the branch of the colonic mesenteric artery was anastomosed to one of the neck arteries, including the inferior thyroid artery in one case, the transverse cervical artery in two cases, and the superior thyroid artery in one case, and all venous anastomoses were performed with the internal jugular veins.Results:The postoperative neck and abdominal wounds healed well without anastomotic leakage, and all patients were able to resume a regular oral diet within 21-30 days postoperatively. During the follow-up of 48-52 months, two cases died due to tumor recurrence, while the remaining two cases were disease-free survivals.Conclusion:Colonic interposition with vascular anastomosis is a safe and reliable reconstruction method suitable for repairing long-segment upper digestive tract defects after resection of hypopharyngeal cancer with esophageal cancer.

Objective:To analyze the status of respiratory pathogen detection and the clinical features in children with Mycoplasma pneumoniae pneumonia (MPP). Methods:A prospective, multicenter study was conducted to collect clinical data, including medical history, laboratory examinations and multiplex PCR tests of children diagnosed with MPP from 4 hospitals in China between November 15 th and December 20 th, 2023. The multiplex PCR results and clinical characteristics of MPP children in different regions were analyzed. The children were divided into severe and mild groups according to the severity of the disease. Patients in the severe group were further divided into Mycoplasma pneumoniae (MP) alone and Multi-pathogen co-detection groups based on whether other pathogens were detected besides MP, to analyze the influence of respiratory pathogen co-detection rate on the severity of the disease. Mann-Whitney rank sum test and Chi-square test were used to compare data between independent groups. Results:A total of 298 children, 136 males and 162 females, were enrolled in this study, including 204 children in the severe group with an onset age of 7.0 (6.0, 8.0) years, and 94 children in the mild group with an onset age of 6.5 (4.0, 7.8) years. The level of C-reactive protein, D-dimer, lactic dehydrogenase (LDH) were significantly higher (10.0 (5.0, 18.0) vs. 5.0 (5.0, 7.5) mg/L, 0.6 (0.4, 1.1) vs. 0.5 (0.3, 0.6) mg/L, 337 (286, 431) vs. 314 (271, 393) U/L, Z=2.02, 2.50, 3.05, all P<0.05), and the length of hospitalization was significantly longer in the severe group compared with those in mild group (6.0 (6.0, 7.0) vs. 5.0 (4.0, 6.0) d, Z=4.37, P<0.05). The time from onset to admission in severe MPP children was significantly shorter than that in mild MPP children (6.0 (5.0, 9.5) vs. 9.0 (7.0, 13.0) d, Z=2.23, P=0.026). All patients completed the multiplex PCR test, with 142 cases (47.7%) MPP children detected with 21 pathogens including adenovirus 25 cases (8.4%), human coronavirus 23 cases (7.7%), rhinovirus 21 cases (7.0%), Streptococcus pneumoniae 21 cases (7.0%), influenza A virus 18 cases (6.0%). The pathogens with the highest detection rates in Tianjin, Shanghai, Wenzhou and Chengdu were Staphylococcus aureus at 10.7% (8/75), adenovirus at 13.0% (10/77), adenovirus at 15.3% (9/59), and both rhinovirus and Haemophilus influenzae at 11.5% (10/87) each. The multi-pathogen co-detection rate in severe MPP children was significantly higher than that in mild MPP group (52.9% (108/204) vs. 36.2% (34/94), χ2=10.62, P=0.005). Among severe MPP children, there are 89 cases in the multi-pathogen co-detection group and 73 cases in the simple MPP group. The levels of LDH, D-dimer and neutrophil counts in the multi-pathogen co-detection group were significantly higher than those in the simple MPP group (348 (284, 422) vs. 307 (270, 358) U/L, 0.8 (0.5, 1.5) vs. 0.6 (0.4, 1.0) mg/L, 4.99 (3.66, 6.89)×10 9vs. 4.06 (2.91, 5.65)×10 9/L, Z=5.17, 4.99, 6.11, all P<0.05). Conclusions:The co-detection rate of respiratory pathogens, LDH and D-dimer in children with severe MPP were higher than those with mild MPP. Among severe MPP children the stress response of children in co-detection group was more serious than that of children with simple MPP.

Objective:To investigate the diagnostic value of lung ultrasound in hospitalized children with community-acquired pneumonia (CAP).Methods:In the cross-sectional study, a total of 422 children with CAP who were hospitalized in the Second Affiliated Hospital and Yuying Children′s Hospital of Wenzhou Medical University, from February 2021 to August 2022 and completed lung ultrasound examination within 48 hours after admission were enrolled. The clinical characteristics, lung ultrasound and chest CT were collected. The patients were divided into two groups according to the signs of pneumonia indicated by chest CT, and the signs of lung ultrasound with diagnostic value were screened according to the signs of pneumonia indicated by chest CT by least absolute shrinkage and selection operator (Lasso) regression. According to severity of the disease, the children were divided into the severe group and the mild group, and the differences of lung ultrasound signs between the two groups were compared. Kruskal-Wallis test, Fisher′s exact test was selected for comparison between groups. Random forest classifier wes used to evaluate the value of lung ultrasound in the diagnosis of CAP and prediction of severe pneumonia in children. The receiver operating characteristic curve was used to evaluate the prediction effect. Use DeLong test to compare the area under the curve.Results:Among the 422 cases of CAP, there were 258 males and 164 females, and the age of onset was 2.8 (1.3, 4.3) years. The confluent B-line, consolidation and pleural effusion detected by lung ultrasound were 309 cases (73.2%), 232 cases (55.0%) and 16 cases (3.8%), respectively, and the size of consolidation was 3.0 (0, 11.0) mm. One hundred and ten children (26.1%) with CAP completed chest CT. There were 90 cases with signs of pneumonia in chest CT and 20 cases without signs of pneumonia. Lasso was used for feature selection.Lung consolidation ( OR=2.46), bilateral lung consolidation ( OR=1.16) and confluent B-line ( OR=1.34) were the main index. With random forest classifier, the accuracy of models using full variables and Lasso-selected variables were 0.79 (95% CI 0.70-0.86) and 0.79 (95% CI 0.70-0.86), the sensitivity were 0.81 and 0.81, and the specificity were 0.75 and 0.70, and the area under curve were 0.87 (95% CI 0.81-0.94, P<0.001) and 0.84 (95% CI 0.76-0.91, P<0.001), respectively. There were 97 cases in severe group and 325 cases in mild group. Compared with the mild group, the detection rate of consolidation, multiple consolidation, the size of consolidation and the size of consolidation was adjusted by body surface area (consolidation size/body surface area) in severe group were higher (66 cases (68.0%) vs. 166 cases (51.1%), 42 cases (43.3%) vs. 93 cases (28.6%), 8.0 (0, 17.0) vs. 1.0 (0, 9.0) mm, 12.5 (0, 24.6) vs. 2.1 (0, 17.6), χ2=8.59, 9.98, Z=14.40, 12.79, all P<0.05). Using lung ultrasound lung consolidation size and consolidation size/body surface area to predict the severe CAP, the optimal cut-off value were 6.7 mm and 10.2, the accuracy was 0.80 (95% CI 0.75-0.83) and 0.89 (95% CI 0.86-0.92), the sensitivity was 0.99 and 0.99, the specificity was 0.14 and 0.56, respectively, and the area under the curve was 0.66 (95% CI 0.60-0.72, P<0.001) and 0.76 (95% CI 0.70-0.83, P<0.001), respectively. The area under the curve of consolidation size/body surface area was higher than that of consolidation size ( Z=5.50, P<0.001). Conclusions:Consolidation and confluent B-line, are important index for lung ultrasound diagnosis of CAP in children. The actual consolidation size adjusted by body surface area is superior to the size of consolidation in predicting severe CAP.

Objective To investigate the effects of long non-coding RNA (LncRNA) solute carrier organic anion transporter family member 4A1 (SLCO4A1-AS1) targeting microRNA-615-5p (miR-615-5p) in esophageal cancer cells on cell proliferation, apoptosis, and expression of inflammatory factors. Methods Real-time quantitative polymerase chain reaction (RT-qPCR) was used to analyze the expression of LncRNA SLCO4A1-AS1 and miR-615-5p in esophageal cancer tissues and cell lines. Eca109 cells were transfected with si-NC, si-LncRNA SLCO4A1-AS1, miR-NC, miR-615-5p mimic, pcDNA, pcDNA-LncRNA SLCO4A1-AS1, si-LncRNA SLCO4A1-AS1+anti-miR-NC, and si-LncRNA SLCO4A1-AS1+anti-miR-615-5p. Cell viability and apoptosis rate were measured by CCK-8 and flow cytometry, respectively; cell proliferation was determined by plate cloning assay; and levels of interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α) in the culture medium were measured using an enzyme-linked immunosorbent assay (ELISA) kit. A dual luciferase reporter gene assay was used to determine the relationship between LncRNA SLCO4A1-AS1 and miR-615-5p. Results Expression of LncRNA SLCO4A1-AS1 was upregulated, and miR-615-5p expression was downregulated in esophageal cancer tissues and cell lines. After inhibiting LncRNA SLCO4A1-AS1 expression, cell viability, the number of cell clones, and levels of IL-6 and TNF-α in the culture medium decreased, while miR-615-5p expression and apoptosis rate increased (P < 0.05). Compared with the miR-NC group, the miR-615-5p group showed increased miR-615-5p expression, levels of Cleaved-caspase-3 protein, and apoptosis rate, and decreased cell viability, the number of cell clones, and levels of IL-6 and TNF-α in the culture medium (P < 0.05). Compared with the si-LncRNA SLCO4A1-AS1+anti-miR-NC group, the si-LncRNA SLCO4A1-AS1+anti-miR-615-5p group showed decreased miR-615-5p expression, levels of Cleaved-caspase-3 protein, and apoptosis rate, and increased cell viability, the number of cell clones, and levels of IL-6 and TNF-α in the culture medium (P < 0.05). Conclusion LncRNA SLCO4A1-AS1 can promote the occurrence and development of esophageal cancer. Inhibiting LncRNA SLCO4A1-AS1 can reduce the proliferation of esophageal cancer cells, decrease the expression of inflammatory factors, and induce apoptosis.
