Objective: To explore the distribution of traditional Chinese medicine (TCM) syndromes in patients with interstitial lung disease (ILD) and its influencing factors. Methods: This cross-sectional study included 385 patients with ILD admitted to the First Affiliated Hospital of Zhejiang Chinese Medical University (Zhejiang Provincial Hospital of Chinese Medicine) from January 2018 to June 2022. Data on sex, age, body mass index, smoking history, respiratory rate, hospitalization time, treatment cost, whether velcro rales can be heard, comorbidities with rheumatic immune diseases, TCM four examination information, and clinical examination results, including CT imaging, D-dimer level, and lung function-related indicators, were collected. The distribution pattern of TCM syndromes in patients with ILD and the association between TCM syndromes and clinical indicators were analyzed using the cluster analysis and binary Logistic regression analysis. Results: Among the 385 patients with ILD, sticky phlegm (59.74%) and shortness of breath (56.10%) were common symptoms, while greasy tongue coating (55.32%), red tongue (52.73%), and slippery and rapid pulse (25.71%) were common tongue and pulse manifestations. The patients were divided into five syndromes using cluster analysis: syndrome of phlegm-heat stagnation in the lung (36.62%), syndrome of turbid phlegm obstructing lung (29.35%), syndrome of deficiency of both qi and yin (12.99%), syndrome of qi deficiency of lung and kidney (11.95%), and syndrome of phlegm and blood stasis obstructing lung (9.09%). The D-dimer level was lower in patients with syndrome of phlegm-heat stagnation in the lung, syndrome of turbid phlegm obstructing lung, syndrome of deficiency of both qi and yin, and syndrome of qi deficiency of lung and kidney than in those with syndrome of phlegm and blood stasis obstructing lung (P<0.05). The percentage of predicted forced vital capacity (FVC%pred) of patients with syndrome of phlegm-heat stagnation in the lung, syndrome of turbid phlegm obstructing lung, syndrome of deficiency of both qi and yin, and syndrome of phlegm and blood stasis obstructing lung was higher than in those with syndrome of qi deficiency of lung and kidney (P<0.05). Among patients aged 60 and above, those with syndrome of phlegm-heat stagnation in the lung, syndrome of phlegm and blood stasis obstructing lung, and syndrome of deficiency of both qi and yin containing dual pathogenic syndrome elements were more likely to experience moderate to severe pulmonary diffusion impairment than those with syndrome of turbid phlegm obstructing lung and syndrome of qi deficiency of lung and kidney containing single pathogenic syndrome elements (P<0.05). The Logistic regression showed that the FVC%pred was an influential factor for syndrome of qi deficiency of lung and kidney, and the area under the receiver operating characteristic (ROC) curve (AUC) between FVC%pred and the formation of syndrome of qi deficiency of lung and kidney was 0.676 (95%CI: 0.598-0.755), P=0.002. The sensitivity was 0.431, the specificity was 0.966, and the best threshold on the ROC curve of 0.397 was 79.1%. The D-dimer level was an influential factor in the formation of syndrome of phlegm and blood stasis obstructing lung. The AUC between D-dimer level and the formation of syndrome of phlegm and blood stasis obstructing lung was 0.729 (95%CI: 0.655-0.802), P<0.001. The sensitivity was 0.914, the specificity was 0.523, and the best threshold on the ROC curve of 0.437 was 0.675 mg/L. Conclusion syndrome of phlegm-heat stagnation in the lung and syndrome of turbid phlegm obstructing lung are common among patients with ILD. Complex pathological syndromes are more likely to exacerbate pulmonary diffusion dysfunction. The FVC%pred can assist in differentiating syndrome of qi deficiency of lung and kidney, whereas the D-dimer level can assist in differentiating syndrome of phlegm and blood stasis obstructing lung.

ObjectiveTo investigate the relationship between serum 25(OH)D and gestational diabetes mellitus in the second trimester (GDM), to analyze the interaction effect of key risk factors, so as to provide a basis for clinical personalized vitamin D supplementation. MethodsA total of 266 pregnant women who registered and took regular obstetric check-ups in Shanghai Pudong New Area Health Care Hospital for Women and Children from June to December 2022, were selected as the research subjects. According to the results of oral glucose tolerance test (OGTT), the subjects were divided into the GDM group (131) and control group (135). The level of serum 25(OH)D at the time of OGTT were detected and other clinical indicators were followed up. ResultsThe age, systolic blood pressure in early pregnancy, pre-pregnancy BMI, FPG, OGTT 1-hour and 2-hour glucose, GHb, HOMA-IR, TG, AST, Cr, D-D, FDP and SF at 35 weeks’ gestation of the pregnant women were higher in the GDM group than that of the pregnant women in the normal group, while gestational weight gain and serum 25(OH)D level were significantly lower than that of the pregnant women in the normal group. Serum 25(OH)D was negatively correlated with HOMA-IR and WBS’s, but positively correlated with TG and ALT. Serum 25(OH)D was non-linearly correlated with the risk of GDM in an inverted J-shape, and there was an interaction effect of advanced age, pre-pregnancy obesity and vitamin D deficiency on the risk of GDM. ConclusionVitamin D is non-linearly associated with the risk of GDM. The risk of GDM is significantly reduced when serum 25(OH)D level ≥30 ng∙mL^-1.

Background::Homoharringtonine (HHT) is an effective anti-inflammatory, anti-viral, and anti-tumor protein synthesis inhibitor that has been applied clinically. Here, we explored the therapeutic effects of HHT in a mouse heart transplant model.Methods::Healthy C57BL/6 mice were used to observe the toxicity of HHT in the liver, kidney, and hematology. A mouse heart transplantation model was constructed, and the potential mechanism of HHT prolonging allograft survival was evaluated using Kaplan–Meier analysis, immunostaining, and bulk RNA sequencing analysis. The HHT-T cell crosstalk was modeled ex vivo to further verify the molecular mechanism of HHT-induced regulatory T cells (Tregs) differentiation. Results::HHT inhibited the activation and proliferation of T cells and promoted their apoptosis ex vivo. Treatment of 0.5 mg/kg HHT for 10 days significantly prolonged the mean graft survival time of the allografts from 7 days to 48 days ( P <0.001) without non-immune toxicity. The allografts had long-term survival after continuous HHT treatment for 28 days. HHT significantly reduced lymphocyte infiltration in the graft, and interferon-γ-secreting CD4 + and CD8 + T cells in the spleen ( P <0.01). HHT significantly increased the number of peripheral Tregs (about 20%, P <0.001) and serum interleukin (IL)-10 levels. HHT downregulated the expression of T cell receptor (TCR) signaling pathway-related genes ( CD4, H2-Eb1, TRAT1, and CD74) and upregulated the expression of IL-10 and transforming growth factor (TGF) -β pathway-related genes and Treg signature genes ( CTLA4, Foxp3, CD74, and ICOS). HHT increased CD4 + Foxp3 + cells and Foxp3 expression ex vivo, and it enhanced the inhibitory function of inducible Tregs. Conclusions::HHT promotes Treg cell differentiation and enhances Treg suppressive function by attenuating the TCR signaling pathway and upregulating the expression of Treg signature genes and IL-10 levels, thereby promoting mouse heart allograft acceptance. These findings may have therapeutic implications for organ transplant recipients, particularly those with viral infections and malignancies, which require a more suitable anti-rejection medication.

Chemical cleaning and disinfection are crucial steps for eliminating infection in root canal treatment.However,irrigant selection or irrigation procedures are far from clear.The vapor lock effect in the apical region has yet to be solved,impeding irrigation efficacy and resulting in residual infections and compromised treatment outcomes.Additionally,ambiguous clinical indications for root canal medication and non-standardized dressing protocols must be clarified.Inappropriate intracanal medication may present side effects and jeopardize the therapeutic outcomes.Indeed,clinicians have been aware of these concerns for years.Based on the current evidence of studies,this article reviews the properties of various irrigants and intracanal medicaments and elucidates their effectiveness and interactions.The evolution of different kinetic irrigation methods,their effects,limitations,the paradigm shift,current indications,and effective operational procedures regarding intracanal medication are also discussed.This expert consensus aims to establish the clinical operation guidelines for root canal irrigation and a position statement on intracanal medication,thus facilitating a better understanding of infection control,standardizing clinical practice,and ultimately improving the success of endodontic therapy.

Goniotomy (GT) is a safe and effective type of minimally invasive glaucoma surgery (MIGS) extensively utilized in China.It is particularly suited for treating primary open-angle glaucoma and advanced primary angle-closure glaucoma.Although GT is generally safe, hyphema and postoperative intraocular pressure (IOP) spikes remain common complications after GT.Currently, there is no standardized protocol for managing these issues, which can impact clinicians' assessment of surgical outcomes and potentially affect the prognosis.Therefore, it is crucial to establish comprehensive and detailed management protocols for perioperative hyphema and IOP spike following GT.This will guide clinical practitioners in managing complications appropriately and systematically, thereby promoting the further development and refinement of MIGS.To address these concerns, several domestic glaucoma treatment experts along with members of the Glaucoma Society of Ophthalmology, Guangdong Medical Association reviewed existing literature and held recommendation meetings to develop a guideline for managing perioperative hyphema and IOP spikes following GT.It includes defining perioperative hyphema in GT, discussing its high-risk factors and outcomes, exploring methods for prevention prior to surgery and techniques to reduce bleeding during the procedure, and managing postoperative hemorrhage.Additionally, it covers defining IOP spikes after GT, investigates their causes and contributing factors, and outlines management strategies and anticipated outcomes to provide a valuable resource for clinicians.

Objective:To investigate the application effect of bullet screen interaction in the teaching of internal medicine of traditional Chinese medicine.Methods:A randomized controlled trial was conducted, and 150 students were randomly divided into bullet screen interaction group and traditional interaction group and received teaching with bullet screen interaction and traditional interaction, respectively. Flanders Interaction Analysis System (FIAS), class rating, questionnaire survey, and performance test were used to evaluate the effect of classroom interaction and teaching achievement. SPSS 22.0 was used to perform the t-test and the chi-square test. Results:Compared with the traditional interaction group, the bullet screen interaction group had a significantly lower teacher's language ratio [(62.63±2.83)% vs. (71.05±3.19)%] and significantly higher student's language ratio [(32.68±2.62)% vs. (22.79±1.32)%], teacher's indirect/direct influence ratio [(96.63±9.59)% vs. (69.84±3.48)%], and teacher's positive/negative influence ratio [(122.89±6.43)% vs. (50.58±2.35)%]. Compared with the traditional interaction group, the bullet screen interaction group had significantly higher scores of teacher's emotional atmosphere (23.82±6.54 vs. 21.01±6.51), quality of classroom activities (25.67±5.51 vs. 22.56±11.95), and information transmission of teacher's classroom interactive activities (25.46±10.30 vs. 18.44±6.52). The questionnaire survey showed that compared with the traditional interaction group, the bullet screen interaction group had a significantly higher number of the students who selected excellent and good for student interest in classroom, dullness of classroom, and the mastery of classroom knowledge [104 (69.33%)/110 (73.33%)/106 (70.67%) vs. 72(48.00%)/74 (49.33%)/84(56.00%)], and the bullet screen interaction group had significantly higher scores of basic knowledge and case analysis than the traditional interaction group (84.30±4.13/78.53±7.21 vs. 79.26±5.67/72.56±4.22).Conclusions:The application of bullet screen interaction teaching in the teaching of internal medicine of traditional Chinese medicine can help to improve interactive effect and teaching achievement.

Objective: To understand campus bullying in colleges and middle schools in Tibet, and to analyze related influencing factors, so as to provide reliable basis and reference for formulating targeted intervention measures. Methods: A stratified cluster sampling method was used to investigate the status and influencing factors of being bullied by questionnaire among 3 875 college and middle school students in Ngari, Qamdo, Lhasa, Nagqu and Xigaze of Tibet, from September to November 2019. Chi-square test and Logistic regression method were used for data analysis. Results: The report rate of campus bullying among college and middle school students in Tibet was 5.50%; 4.35% for girls and 6.76% for boys；8.81% for college students, 1.64% for senior high school students and 5.94% for junior high school students. The results of multivariate Logistic regression analysis showed that smoking ( OR =1.71), Internet addiction ( OR =3.82), depression ( OR =3.84), obesity ( OR =2.02), single parent family ( OR = 1.67 ) and reorganized family ( OR =3.74) were positively correlated with campus bullying ( P <0.05). Girls ( OR =0.66) and senior high school ( OR =0.28) were negatively correlated with campus bullying ( P <0.05). Conclusion Campus bullying is related to campus environment, family type, behaviors and life styles, etc. Efforts should be committed to build a caring campus culture and a good family moral education environment, in order to reduce the incidence of campus bullying and associated adverse effects.

Objective:To investigate the clinical features of diagnosis and treatment of renal parenchymal invasive urothelial carcinoma.Methods:The clinical data of 23 patients with renal parenchymal invasive urothelial carcinoma admitted to Beijing Chaoyang Hospital Affiliated to Capital Medical University from January 2014 to December 2020 were retrospectively analyzed. There were 12 males and 11 females. The mean age was (67.3±10.1) years old. Among them, 7 cases complained of painless hematuria and 9 cases were asymptomatic. Three cases underwent preoperative MRI examination, 19 patients underwent preoperative enhanced CT examination, and 1 patient underwent both MRI and enhanced CT examination. MRI examination showed renal lobulated and other T1 mixed with T2 signals, the boundary was not clear, and DWI showed obvious restricted diffusion. The tumor was located on the left side in 15 cases and on the right side in 8 cases. Preoperative diagnosis was made by fine needle aspiration biopsy in 1 patient, and specimens were obtained by flexible ureteroscope in 2 patients. No tumor was reported. The preoperative diagnosis of 22 patients was unclear and the nature of the tumor could not be determined. One patient was considered to have urothelial carcinoma by fine needle aspiration. All patients were treated by surgery, including 20 cases of laparoscopic radical nephrectomy and 3 cases of nephroureterectomy with bladder sleeve resection.Results:Postoperative pathological specimens showed yellow-white mass, high-grade invasive urothelial carcinoma invading renal parenchyma. Nine cases were T 3a stage, 14 cases were T 3b stage, and 5 cases were lymph node metastasis. The average postoperative follow-up time was (18.6±6.72)months, 2 patients were lost to follow-up, 8 patients died, and the overall mortality rate was 38.1%. Seven patients died of recurrence or metastasis. There were 3 cases of bladder recurrence and 5 cases of metastasis after operation. Conclusions:Renal parenchymal infiltrating urothelial carcinoma is difficult to diagnose in the early stage, with poor clinical biological behavior and poor overall prognosis. For patients diagnosed with renal parenchymal invasive urothelial carcinoma preoperatively, laparoscopic nephroureterectomy + bladder sleeve resection is recommended.

Objective:Based on the principle that the aggregation-induced emission (AIE) fluorescent probe 6PD-DPAN could bind and aggregate with bacteria, and the fluorescence intensity could reflect the quantity of bacteria, a new method for rapid, convenient, and accurate bacterial drug sensitivity testing was established, which provided a basis for rapid and accurate clinical drug use.Methods:This was a methodological evaluation study. A total of 107 clinical isolates were collected from Houjie Hospital of Dongguan City from January to December 2022, among which 46 isolates were used for the establishment of the new method, and 61 isolates were used for methodological validation. The minimum inhibitory concentration (MIC) determined by broth microdilution method was used as the gold standard, and three antibacterial drugs, gentamicin, levofloxacin, and cefotaxime, were used as experimental drugs. The AIE plate was incubated for 4 hours, and the fluorescence intensity was measured every half an hour to draw a fluorescence change curve. The MIC results were compared with the CLSI breakpoints to determine the bacteria as sensitive, intermediate, or resistant. To simplify the detection process, the ratio of fluorescence intensity at 4 hours(R) was calculated, and the ROC curve was used to analyze the efficacy of R in determining bacterial growth and establish its cutoff value. The new method was used to determine the MIC of 61 clinical isolates, with broth microdilution method as the gold standard. The basic consistency, categorical consistency, very major errors, and major errors of the new method were analyzed, and the consistency between the two methods was determined by the Kappa test.Results:ROC curve analysis of the R after 4 hours of culture: The cut-off value was 3.0, with both sensitivity and specificity for determining bacterial growth being 100%. The median (interquartile) R for bacterial growth inhibition was 11.1 (8.6, 14.4); the median R-value for bacterial growth was 1.1 (1.0, 1.2). Compared to the gold standard, the newly established method showed 100% (61/61) essential agreement in detecting MICs of 61 clinical isolates, with a categorical agreement of 96.7% (59/61). There were no very major or major errors, and the Kappa value was 0.94, indicating good consistency between the newly established method and the microbroth dilution method.Conclusions:This study successfully established a new method for bacterial drug sensitivity testing based on AIE technology, which could obtain satisfactory results within 5 hours, providing a basis for early precision drug treatment in clinical practice.

Objective: To explore the association between self-reported gingival bleeding and prevalent hypertension among adults in Zhejiang with a cross-sectional study. Methods: After excluding participants with self-reported, physician-diagnosed heart diseases, stroke, diabetes, cancer, and those who never or rarely brush their teeth at baseline study, 48 625 participants aged 30-79 in the China Kadoorie Biobank (CKB) study from Tongxiang, Zhejiang were included for the final analysis. Three multivariable logistic regression models were used to estimate the odds ratios (ORs) for the associations of self-reported gingival bleeding with prevalent hypertension. Results: The mean age of women was (51.2±9.2) years, and 42.9% of participants had prevalent hypertension. The percentage of self-reported frequent gingival bleeding was 6.56% (95%CI: 6.38%-6.75%), significantly higher among women (8.08%, 95%CI: 7.82%-8.35%) than among men (4.36%, 95%CI: 4.12%-4.60%) (P<0.001). After adjusting for socio-demographic factors, behavioral lifestyle, sleep duration, BMI, waist circumference, snoring, in comparison with men whose gingivae never or rarely bleed while brushing teeth, the odds ratio (95%CI) of hypertension for those with occasional, and frequent gingival bleeding were 1.04 (0.96-1.12) and 1.18 (1.02-1.37), respectively (trend P =0.038). The corresponding figures for women were 0.96 (0.91-1.02) and 0.95 (0.86-1.05), respectively (trend P=0.344). Conclusion: Frequent gingival bleeding was positively associated with prevalent hypertension among men.
