Objective: To analyze the association of eating dining locations and their association with nutritional status among Chinese children aged 6-17 years,so as to provide reference for guiding children s reasonable diet. Methods: Stratified random cluster sampling was used to select children aged 6 to 17 years from 28 cities and rural areas of 14 provinces in East, North, Central, South, Southwest, Northwest, Northeast of China, and a total of 52 535 children were included in the study from 2019 to 2021. Information including dining locations, demographic characteristics, dietary intakes and physical activity were collected through a questionnaire survey. Fasting body height and weight were measured in the morning. Unordered multiclass Logistic regression analysis was conducted to assess the relationship between dining locations and nutritional status in children. Results: Regarding children s dining locations, 66.3% ate breakfast at home,25.8% ate breakfast at school,7.9% ate breakfast outside (small dining tables, restaurants, stalls, etc.); 67.7% ate dinner at home,29.0% ate dinner at school,3.3% ate dinner outside; and 63.6% ate lunch at school,30.8% ate lunch at home,5.7% ate lunch outside. The prevalence rates of overweight/obesity and undernutrition were 28.6% and 9.3%, respectively. The adjusted multiclass Logistic regression analysis (controlling for age, region, parental education, household income, total energy intake, and moderate-to-vigorous physical activity) demonstrated that, compared to eating at home, school based breakfast and dinner consumption was associated with significantly lower overweight/obesity risks for both genders (boys: breakfast OR =0.70, 95% CI =0.65-0.75; dinner OR =0.80, 95% CI = 0.74- 0.86; girls: breakfast OR = 0.89 , 95% CI = 0.82-0.96; dinner OR =0.88, 95% CI =0.81-0.95), whereas eating lunch away from home significantly increased overweight/obesity risks (boys: OR =1.32, 95% CI =1.17-1.48; girls: OR =1.43, 95% CI =1.26- 1.62 ), with all associations being statistically significant ( P <0.05). After adjusting for confounding factors, boys who ate breakfast away from home showed a significantly reduced risk of undernutrition ( OR =0.80,95% CI =0.66-0.97), while those consuming lunch away from home had an increased risk ( OR =1.26, 95% CI =1.01-1.57) ( P <0.05). Conclusions The choice of dining locations for children is becoming more diverse, and a relatively high proportion of children eat meals outside the home and at school. Eating out have a higher risk of malnutrition for children. School feeding may be beneficial to children s physical health.

The theory of"lung governing skin and hair"has always occupied an important position in the clinical practice of traditional Chinese medicine.However,in western medicine,the close correlation between the lungs and the skin in health and disease has not been established.The difference between these two medical views has triggered an urgent need for the scientific interpretation and clinical application of the theory of"lung governing skin and hair"in western medicine.Therefore,the purpose of this paper is to discuss the application of"lung governing skin and hair"in chinese medicine and the correlation between the lung and the skin in western medicine from the connotation and history of"lung governing skin and hair"in Chinese medicine.In addition,we will discuss the common pathologic biomarkers of lung and skin diseases in western medicine and the co-morbidities between lung and skin,with the aim to provide new ideas for the clinical diagnosis and treatment of lung and skin diseases and modern research,as well as providing a direction for the integration of the theory of"lung governing skin and hair"into the clinical practice of western medicine.

Objective To explore the mechanism of Lkb1 regulated epithelial regeneration in asthma by airway organoid culture.Methods Lkb1f/f(the control group,n=10)and Scgb1a1CreER;Lkb1f/fmice(the Lkb1 knockout group,n=9)were taken to establish allergic asthma models by aerosol inhalation of ovalbumin(OVA).Bronchial lavage fluid(BALF)and lung tissue were collected.The number of inflammatory cells in BALF were counted.The amount of CLCA3 positive cells was compared by immunofluorescence staining of lung tissue sections.Club cells were selected by flow cytometry for organoid culture.The average diameter of organoids and organoid formation rate were calculated.Expression levels of goblet cell marker CLCA3,cilia cell markers FOXJ1 and AMPK in Club cells were detected by RT-PCR.Results There were no significant differences in the number of macrophages,eosinophils,neutrophils and lymphocytes in BALF between the control group and the Lkb1 knockout group.The number of CLCA3 positive cells were decreased after Lkb1 knockout.Results of organoid culture showed that the average diameter of organoids derived from Club cells and organoid formation rate were decreased after the absence of Lkb1.The expression of FOXJ1 was reduced.After Lkb1 deletion,the expression of AMPKα in Club cells were decreased and the proliferation of Club cells was inhibited.Activation of AMPK,the downstream signaling pathway of Lkb1,could attenuate the effect of Lkb1 deficiency on the regeneration of Club cells.Conclusion Lkb1 promotes the proliferation of airway progenitor cells by AMPK pathway.

Objective:To investigate the clinical significance of tumor budding as an indicator of postoperative distant organ metastasis after radical gastrectomy in elderly patients diagnosed with gastric cancer.Methods:The clinical and pathological data of 124 elderly patients who experienced metastasis after undergoing radical gastrectomy were retrospectively analyzed.The analysis was conducted from March 2015 to June 2022, focusing on the clinicopathological factors that influenced the occurrence of postoperative distant metastasis in these patients.Tumor budding in gastric cancer tissues was assessed using hematoxylin-eosin staining, and its clinical significance was analyzed.Results:The tumor budding grade of gastric cancer tissues showed a significant correlation with vascular invasion( χ2=6.731, P=0.009), the number of lymph node metastases( rs=0.481, P<0.001), and the time of distant metastasis( rs=-0.450, P<0.001).In the univariate analysis, factors such as tumor budding grade, tumor size, vascular invasion, postoperative chemotherapy, cancerous nodule, preoperative serum carbohydrate antigen 125, and the number of lymph node metastases were found to influence distant metastasis-free survival after radical gastrectomy in elderly patients(all P<0.05).The multifactorial analysis also indicated that tumour outgrowth grade was an important independent prognostic factor for postoperative distant metastasis in elderly gastric cancer patients( HR=3.731, P<0.001). Conclusions:The findings of this study indicate that tumor budding may serve as a potential marker for predicting distant organ metastasis in elderly patients who have undergone radical gastrectomy.This discovery holds significant clinical implications.

OBJECTIVE To explore the protective mechanism of amifostine on acute radiation injury mice. METHODS Thirty C57BL/6J mice were randomly divided into normal control group， model group and amifostine group （150 mg/kg）， with 10 mice in each group. Thirty minutes before irradiation， the mice in the amifostine group were intraperitoneally injected with amifostine； normal control group and model group were given constant volume of normal saline intraperitoneally； then acute radiation injury was induced by 4 Gy X-ray radiation in both model group and amifostine group. The white blood cell count （WBC）， platelet count and red blood cell （RBC） count in mice were detected 2 hours before irradiation and on days 1， 4， 7， 10 and 14 after irradiation； the changes in the proportion of WBC （neutrophils， lymphocytes and monocytes） on the 7th day after irradiation were analyzed. The 16S rRNA high-throughput sequencing was used to analyze the structure of gut microbiota in mice feces on the 7th day after irradiation， then its correlation with WBC was analyzed. RESULTS The counts of WBC on the 1st， 4th， 7th and 10th day after irradiation， platelet count on the 10th day after irradiation and RBC count on the 1st day after irradiation in the amifostine group were significantly higher than those in model group （P＜0.05）. Compared with normal control group，β diversity of gut microbiome showed significant change， relative abundance of Firmicutes increased and that of Bacteroidetes decreased in model group. Amifostine could reverse the change in β diversity of gut microbiome， and the relative abundance of Bacteroidetes and Firmicutes. The model group consisted of four distinct species， namely Allobaculum， Erysipelotrichia， Erysipelotrichales and Erysipelotrichaceae， which were significantly negatively correlated with the proportion of peripheral blood lymphocytes （P＜0.01）； amifostine group consisted of two distinct species， namely Lactobacillus murinus and L. crispatus， which were significantly negatively correlated with the proportion of neutrophils （P＜0.05）. CONCLUSIONS Amifostine significantly improves irradiation-induced injury by regulating dysbiosis of LY201816） gut microbiota.

OBJECTIVE: To investigate the effects of fecal microbiota transplantation (FMT) on intestinal microbiome and organism in patients with severe pneumonia during the convalescence period. METHODS: A prospective non-randomized controlled study was conducted. From December 2021 to May 2022, patients with severe pneumonia during the convalescence period who received FMT (FMT group) and patients with severe pneumonia during the convalescence period who did not receive FMT (non-FMT group) admitted to the First Affiliated Hospital of Guangzhou Medical University were enrolled. The differences of clinical indicators, gastrointestinal function and fecal traits between the two groups were compared 1 day before and 10 days after enrollment. The 16S rDNA gene sequencing technology was used to analyze the changes of intestinal flora diversity and different species in patients with FMT before and after enrollment, and metabolic pathways were analyzed and predicted by Kyoto Encyclopedia of Genes and Genomes database (KEGG). Pearson correlation method was used to analyze the correlation between intestinal flora and clinical indicators in FMT group. RESULTS: The level of triacylglycerol (TG) in FMT group was significantly decreased at 10 days after enrollment compared with before enrollment [mmol/L: 0.94 (0.71, 1.40) vs. 1.47 (0.78, 1.86), P < 0.05]. The level of high-density lipoprotein cholesterol (HDL-C) in non-FMT group was significantly decreased at 10 days after enrollment compared with before enrollment (mmol/L: 0.68±0.27 vs. 0.80±0.31, P < 0.05). There were no significant differences in other clinical indexes, gastrointestinal function or fecal character scores between the two groups. Diversity analysis showed that the α diversity indexes of intestinal flora in FMT group at 10 days after enrollment were significantly higher than those in non-FMT group, and β diversity was also significantly different from that in non-FMT group. Differential species analysis showed that the relative abundance of Proteobacteria at the level of intestinal flora in FMT group at 10 days after enrollment was significantly lower than that in non-FMT group [8.554% (5.977%, 12.159%) vs. 19.285% (8.054%, 33.207%), P < 0.05], while the relative abundance of Fusobacteria was significantly higher than that in non-FMT group [6.801% (1.373%, 20.586%) vs. 0.003% (0%, 9.324%), P < 0.05], and the relative abundance of Butyricimonas, Fusobacterium and Bifidobacterium at the genus level of the intestinal flora was significantly higher than that in non-FMT group [Butyricimonas: 1.634% (0.813%, 2.387%) vs. 0% (0%, 0.061%), Fusobacterium: 6.801% (1.373%, 20.586%) vs. 0.002% (0%, 9.324%), Bifidobacterium: 0.037% (0%, 0.153%) vs. 0% (0%, 0%), all P < 0.05]. KEGG metabolic pathway analysis showed that the intestinal flora of FMT group was changed in bisphenol degradation, mineral absorption, phosphonate and phosphinate metabolism, cardiac muscle contraction, Parkinson disease and other metabolic pathways and diseases. Correlation analysis showed that Actinobacteria and prealbumin (PA) in intestinal flora of FMT group were significantly positively correlated (r = 0.53, P = 0.043), Bacteroidetes was positively correlated with blood urea nitrogen (BUN; r = 0.56, P = 0.029) and complement C3 (r = 0.57, P = 0.027), Firmicutes was positively correlated with BUN (r = 0.56, P = 0.029) and complement C3 (r = 0.57, P = 0.027), Fusobacteria was significantly positively correlated with immunoglobulin M (IgM; r = 0.71, P = 0.003), Proteobacteria was significantly positively correlated with procalcitonin (PCT; r = 0.63, P = 0.012) and complement C4 (r = 0.56, P = 0.030). CONCLUSIONS FMT can reduce TG level, reconstruct intestinal microecological structure, change body metabolism and function, and alleviate inflammatory response by reducing the relative abundance of harmful bacteria in patients with severe pneumonia during the convalescence period.

Objective:To investigate the value of cystatin C (Cys-C) in the early diagnosis of acute kidney injury (AKI) after radical nephrectomy and the predictive value for the prognosis of Cys-C based estimated glomerular filtration rate (eGFR Cys-C) after surgery. Methods:The clinical data of 118 patients who underwent unilateral radical nephrectomy in our hospital from January 2019 to December 2020 were retrospectively analyzed. According to the diagnostic criteria of AKI, they were divided into AKI group of 75 cases and no-AKI group of 43 cases. AKI group was (62.7±10.7) years old, with 49 males and 26 females. The no-AKI group was (62.3±12.8) years old, with 21 males and 22 females. The urea nitrogen was (4.9±1.3) mmol/L, creatinine (75.7±14.5)μmol/L, Cys-C (0.85±0.22) mg/L, eGFR Cr(76.3±11.2)ml/(min·1.73m 2), and eGFR Cys-C(101.4±17.4)ml/(min·1.73m 2)in AKI group before operation.In no-AKI group, preoperative urea nitrogen was (4.9±1.5) mmol/L, creatinine (74.5±13.1)μmol/L, Cys-C (0.81±0.29) mg/L, eGFR Cr(78.6±12.5)ml/(min·1.73m 2), and eGFR Cys-C(99.3±18.8)ml/(min·1.73m 2), and there were no significant differences in the values of urea nitrogen, creatinine, Cys-C and eGFR between the two groups before surgery ( P>0.05). ROC curve was used to analyze the diagnostic value of urea nitrogen, creatinine, Cys-C, eGFR calculated based on creatinine and Cys-C at 48h after surgery, and binary Logistic regression was used to analyze the risk factors for AKI. The creatinine status of patients diagnosed with SPS was evaluated 6 months after surgery, based on the definition of Cys-C based eGFR being less than 70% of creatinine-based eGFR(SPS=eGFR Cys-C/ eGFR Cr≤0.7). Results:In AKI group, creatinine was(115.2±22.1)μumol/L, Cys-C (1.8±0.27) mg/L, eGFR Cr (51.6±9.6)ml/(min·1.73m 2), and eGFR Cys-C(43.4±8.5)ml/(min·1.73m 2)48 h after operation. The creatinine was(92.7±13.3)μmol/L, Cys-C(1.3±0.23) mg/L, eGFR Cr(62.2±11.3)ml/(min·1.73m 2), and eGFR Cys-C(61.5±9.5)ml/(min·1.73m 2) in no-AKI group, and difference were statistically significant between the two groups ( P<0.01). ROC curve was used to analyze the diagnosis of AKI. Creatinine, Cys-C, eGFR Cr and eGFR Cys-Cwere all of diagnostic value for AKI (all P<0.01), and AUC(Area under curve) were 0.809, 0.889, 0.761 and 0.925 respectively. The sensitivity, specificity and area under the curve of eGFR Cys-C were 93.3%, 74.4% and 92.5% respectively. Binary Logistic regression analysis showed that creatinine( OR=10.851, 95% CI 2.322-50.688, P=0.004), Cys-C( OR=10.016, 95% CI 2.306-43.362, P=0.001), eGFR Cr( OR=17.923, 95%CI 3.216-53.172, P=0.001) and eGFR Cys-C( OR=19.817, 95% CI 3.367-55.263, P=0.001)were all independent risk factors for AKI. The predictive accuracy of eGFR Cys-C, creatinine, Cys-C, eGFR Cr were 91.6%, 85.7%, 90.2%, 88.5%, respectively. There were 15 cases were confirmed SPS in the AKI group, and only 2 cases were confirmed SPS in the no-AKI group, indicating patients in the AKI group developed more SPS than those in the no-AKI group, with statistically significant difference(Kappa value was 5.22, P=0.02). The 6-month follow-up showed that the creatinine of confirmed SPS was (103.8±23.4)μmol/L and the creatinine of unconfirmed SPS was (86.8±27.2)μmol/L, with statistically significant difference ( P<0.01). Conclusions:eGFR Cys-C calculated based on Cys-C has high sensitivity in diagnosing AKI and has early diagnostic value. Patients diagnosed with SPS based on eGFR Cys-C had higher creatinine 6 months after surgery.

OBJECTIVES: This study aimed to investigate the accuracy of model superimposition and automatic analysis for upper and lower dentition widths in iTero Progress Assessment during the clear aligner process. METHODS: Nineteen cases were included in this retrospective case control study. Pretreatment dental cast (T0) and post treatment dental cast after staged treatment (T1) were available for three-dimensional (3D) model superimposition. The movements of maxillary teeth in the horizontal plane (cross section) after staged treatment and the widths of upper and lower dentitions were measured by 3D model superimposition in real world and iTero Progress Assessment. The data collected from the two methods were compared. RESULTS: The movements [Median (upper and lower quartiles)] of maxillary teeth in the horizontal plane after staged treatment were 2.31 (1.59, 3.22) and 1.79 (1.21, 3.03) mm in iTero Progress Assessment and 3D model analysis, respectively. Significant difference was observed between the two groups (P<0.05). In the measurement of upper and lower dentition width, four indicators were measured, including intercanine width upper, intermolar width upper, intercanine width lower, and intermolar width lower. Before treatment, the measurement of iTero Progress Assessment were (35.78±2.49), (56.21±2.51), (27.43±1.38), (52.26±2.91) mm, respectively, and actual measurement were (35.77±2.53), (56.17±2.47), (27.40±1.41), (52.30±2.86) mm, respectively, without significant difference (P>0.05). After stage treatment, the measurement of iTero Progress Assessment were (37.37±2.86), (57.76±2.56), (28.89±2.00), (54.16±2.19) mm, respectively, and actual measurement were (37.29±2.94), (57.71±2.63), (28.88±2.05), (54.01±2.15) mm, respectively, and there was no significant difference (P>0.05). CONCLUSIONS The data from iTero Progress Assessment did not coincide with the model superimposition results with palate as reference. The accuracy of model superimposition in iTero Progress Assessment needs further investigation, whereas the arch width analysis is accurate. Therefore, iTero Progress Assessment results should be interpreted with caution by orthodontists in clinical applications.
