This paper summarized professor WU Mianhua's experience in the treatment of tumors using Hehuanhua （Flos Albiziae）. He believes that the occurrence and development of tumors are closely related to emotions， and thereafter proposed the concept of "masses usually due to constraint， and should be treated by regulating the spirit".Hehuanhua is a light and aromatic flower that enters the heart， liver and spleen meridians， and is good at relieving constraint and regulating the spirit， harmonizing the center with aroma， which can be used to treat all kinds of tumor-related complications. Hehuanmi is flower buds， picked before the flowers fully blooms， have the effect of clearing and lightening upward， opening up the heart and mind， and unblocking liver qi. Commonly used formulas include self-made Ningxin Anmian Decoction （宁心安眠汤） to treat tumor-related insomnia， self-made Aitongxiao Formula （癌痛消方） to treat tumor-related pain， self-made Erhua Jieyu Formula （二花解郁方） to treat tumor-associated depression， and self-made Shugan Tiaohe Decoction （疏肝调和汤） to deal with peri-menopausal state after the treatment of tumors. Hehuanhua is an inflorescence， which captures the aromatic essence and has the function of removing the filth and turbidity， and can wake up the spleen and harmonize the stomach； therefore， it is often used in self-made Tiaomu Hezhong Decoction （调木和中汤） to treat chemotherapy-related digestive tract adverse reactions or combined with rose flowers to treat chemotherapy-induced oral ulcers.

Objective:To investigate the clinical characteristics of omphalocele, and to assess the risk factors associated with adverse outcomes.Methods:A retrospective cohort study was conducted. Clinical data of 224 patients diagnosed with omphalocele, who were hospitalized at Children′s Hospital, Zhejiang University School of Medicine from January 2013 to December 2022, were collected. Based on their discharge outcomes, the patients were classified into 2 groups: favorable outcomes and unfavorable outcomes. Chi-square test or continuity correction χ2 test or Fisher exact probability method, and Mann-Whitney U test were used for intergroup comparisons. Logistic regression analysis was performed to identify risk factors associated with adverse outcomes in omphalocele. Results:Among the 224 patients with omphalocele, 126 were male. A total of 208 patients (92.9%) had favorable outcomes, while 16 patients (7.1%) had unfavorable outcomes. In the unfavorable outcomes group, 14 patients had giant omphaloceles, while 100 patients had giant omphaloceles in the favorable outcomes group. The rates of herniation of more than two intra-abdominal organs in the hernial sac, congenital heart defects, patent ductus arteriosus, pulmonary hypertension, sepsis and infection of the hernial sac, were all higher in the unfavorable outcomes group compared to the favorable outcomes group (all P<0.05). Patients with unfavorable outcomes had longer mechanical ventilation time, duration of oxygen use, duration of parenteral nutrition, hospital stays, and higher rates of parenteral nutrition-associated cholestasis compared to those with favorable outcomes (all P<0.01). Multivariate Logistic regression analysis indicated that pulmonary hypertension ( OR=9.39, 95% CI 1.20-73.32), sepsis ( OR=8.59, 95% CI 1.32-55.86), and congenital heart defects ( OR=6.55, 95% CI 1.11-38.73) were all independent risk factors for adverse outcomes in omphalocele (all P<0.05). Conclusions:Infants with omphalocele are prone to complications such as cardiovascular malformations, infections, and pulmonary hypertension. Adverse outcomes in omphalocele are associated with pulmonary hypertension, sepsis, and congenital heart defects.

Objective To investigate the situation and influencing factors of preserved ratio impaired spirometry (PRISm) among dust-exposed workers in a wooden furniture manufacturing enterprise. Methods A total of 562 dust-exposed workers from a wooden furniture enterprise in Guangdong Province were selected as the study subjects using the convenience sampling method. The result of health-status questionnaire and occupational medical examinations among the participants were studied, and the influencing factors of PRISm were studied using the binary logistic regression analysis method. Results The detection rate of PRISm was 22.1% (124/562) among the study subjects. Binary logistic regression result showed that male workers had a higher risk of PRISm than female workers (P<0.01). Current smokers had a higher risk of PRISm than non-smokers (P<0.05). Workers with longer duration of exposure to occupational hazards had a higher risk of PRISm (P<0.05), those with higher grade of small-airway dysfunction had a higher risk of PRISm (P<0.01). In terms of body mass index, overweight or obese workers showed a higher detection rate of PRISm than those with normal weight (P<0.01). Greater amount of smoking pack per year had a higher risk of PRISm (P<0.01). Conclusion Dust-exposed workers in the wooden furniture manufacturing industry show a relatively high detection rate of PRISm. Male, current smoker, longer duration of exposure to occupational hazards, small airway dysfunction, overweight or obese, and smoking pack per year are influencing factors of PRISm among the dust-exposed workers in the wooden furniture manufacturing industry.

The pancreatojejunostomy is one of the most challenging steps in pancreatic reconstruction surgery,and its success directly impacts the patient's prognosis.The pancreas has characteristics such as being narrow at the top and wide at the bottom,fragile in texture,rich in digestive enzymes,and subject to constant intestinal peristalsis.These factors can easily lead to the loosening of the pancreatojejunostomy site and the occurrence of postoperative pancreatic fistula.Through mechanical modeling analysis and a summary of clinical practice,the authors propose a pancreatojejunostomy method based on mechanical principles.This method is summarized as"1-tube,2-needle,3-suture"method,which refers to one pancreatic duct stent tube,two types and two strands of different sutures,and three different suturing techniques.This article will provide a detailed introduction to this operative method and deeply analyze its technical principles.Additionally,a retrospective analysis of cases from the authors'center found that this method can effectively reduce the incidence of postoperative pancreatic fistula.

Objective:To investigate the correlation between hearing loss and microvascular complications in diabetes.Methods:This cross-sectional study conducted the data from 572 patients with diabetes hospitalized in the Endocrinology Department of the General Hospital of Southern Theater Command from September 2022 to July 2023. All participants underwent electrical audiometry and acoustic immittance in the ENY department. Based on the audiometric results, participants were categorized into normal hearing group and hearing loss group. Additionally, 572 non-diabetic patients from the outpatient department were enrolled as the non-diabetic group. The general information and laboratory results were collected and compared using t test, rank sum test or χ2 test. Binary logistic regression analysis was used to evaluate the association of diabetic hearing loss with diabetic kidney disease(DKD), diabetic retinopathy (DR), and diabetic peripheral neuropathy (DPN). Results:Among 572 patients with diabetes, 429 suffered from hearing loss and 143 were normal. χ2 test showed significant differences in combined DKD and DPN between two groups, but not in DR. Multivariate binary logistic regression analysis identified DKD and DPN as risk factors for hearing loss, but no correlation was found with DR. Conclusion:Diabetic patients with DKD or DPN should be monitored for potential hearing loss. Early screening and treatment are crucial to prevent severe hearing impairment.

Evidence indicates that metabolic reprogramming characterized by the changes in cellular metabolic patterns contributes to the pathogenesis of pulmonary fibrosis(PF).It is considered as a promising ther-apeutic target anti-PF.The well-documented against PF properties of Tanshinone ⅡA(Tan ⅡA)have been primarily attributed to its antioxidant and anti-inflammatory potency.Emerging evidence suggests that TanⅡA may target energy metabolism pathways,including glycolysis and tricarboxylic acid(TCA)cycle.However,the detailed and advanced mechanisms underlying the anti-PF activities remain obscure.In this study,we applied[U-13C]-glucose metabolic flux analysis(MFA)to examine metabolism flux disruption and modulation nodes of Tan ⅡA in PF.We identified that Tan ⅡA inhibited the glycolysis and TCA flux,thereby suppressing the production of transforming growth factor-β1(TGF-β1)-dependent extracellular matrix and the differentiation and proliferation of myofibroblasts in vitro.We further revealed that Tan ⅡA inhibited the expression of key metabolic enzyme hexokinase 2(HK2)by inhibiting phosphoinositide 3-kinase(PI3K)/protein kinase B(Akt)/mammalian target of rapamycin(mTOR)/hypoxia-inducible factor 1α(HIF-1α)pathway activities,which decreased the accumulation of abnormal metabolites.Notably,we demonstrated that Tan ⅡA inhibited ATP citrate lyase(ACLY)activity,which reduced the collagen synthesis pathway caused by cytosol citrate consumption.Further,these results were validated in a mouse model of bleomycin-induced PF.This study was novel in exploring the mechanism of the occurrence and develop-ment of Tan ⅡA in treating PF using 13C-MFA technology.It provided a novel understanding of the mechanism of Tan ⅡA against PF from the perspective of metabolic reprogramming.

OBJECTIVE To analyze the influential factors for rivaroxaban-induced bleeding events in patients with non- valvular atrial fibrillation （NVAF） and coronary heart disease. METHODS A total of 64 hospitalized patients with NVAF complicated with coronary heart disease who were treated with rivaroxaban and admitted to the Fuzhou University Affiliated Provincial Hospital from November 2021 to May 2023 were included in this retrospective study. The demographic data， laboratory test indexes and other general clinical data， and steady-state trough concentration of rivaroxaban were collected， and the dose- adjusted trough concentration was calculated. The occurrence of bleeding events within 6 months after discharge was recorded. The univariate analysis and binary Logistic regression analysis were adopted to determine the independent risk factors of rivaroxaban- related bleeding events. The binary Logistic regression equation was constructed to predict the probability of bleeding events. The area under the receiver operator characteristic （ROC） curve （AUC） was used to analyze the predictive value of the regression equation. RESULTS Among 64 patients， 19 patients had 24 case-times bleeding events， most of which were mild bleeding （19 case-times， 79.2%）， and mainly gastrointestinal bleeding （17 case-times， 70.8%）. After symptomatic treatment and adjustment of the anticoagulant regimen， most of them were improved or cured. In the univariate analysis， the proportion of patients with a history of anemia， platelet count， urea nitrogen content， steady-state trough concentration of rivaroxaban， dose-adjusted trough concentration and coagulation indexes [international normalized ratio， prothrombin time （PT）， activated partial thromboplastin time] in bleeding group were significantly more or higher than those in non-bleeding group， while the albumin level was significantly lower than that in non-bleeding group （P＜0.05）. In binary Logistics regression analysis， high PT level （odds ratio＝1.473， 95% confidence interval＝1.103-1.967， P＝ 0.009） and high rivaroxaban dose-adjusted trough concentration （odds ratio＝1.174， 95% confidence interval＝1.018-1.355， P＝ 0.027） were independent risk factors for rivaroxaban-related bleeding events. The binary Logistic regression equation of bleeding event prediction probability （P） was LogitP＝－6.975+0.387×PT level+0.161×dose-adjusted trough concentration， and the AUC of the ROC curve was 0.825 （95% confidence interval was 0.708-0.909， P＜0.001）. CONCLUSIONS The risk factors of rivaroxaban-related bleeding events in patients with NVAF and coronary heart disease include previous anemia history， high platelet count， high urea nitrogen content， high rivaroxaban steady-state trough concentration， high dose-adjusted trough concentration， high coagulation indexes and low albumin level. High PT level and high dose-adjusted trough concentration are independent risk factors that can be used to predict the risk of rivaroxaban-induced bleeding events. The regression equation has good predictive value.

Objective: To investigate the characteristics of HIV-1 molecular transmission network among HIV/AIDS patients in Zhoushan City, Zhejing Province. Methods: The newly reported HIV/AIDS cases in Zhoushan City from 2020 to 2022 were selected. Basic information was collected and whole blood samples were obtained at the initial follow-up. The pol gene sequences of HIV-1 were amplified by RT-PCR and nested-PCR. HIV-1 subtypes were identified by Neighbor-Joining phylogenetic trees. The HIV-1 molecular transmission network was built and analyzed using Cytoscape 3.6.1 software. Results: A total of 222 HIV/AIDS cases were reported in Zhoushan City from 2020 to 2022, 200 whole blood samples were collected, and 152 sequences were obtained successfully, including 122 males (80.26%), 75 cases aged 50 years and above (49.34%), 109 cases with a junior high school education or below (71.71%), and 63 cases with commercial heterosexual contact (41.45%). The main subtypes were CRF07_BC and CRF01_AE, accounting for 45.39% and 21.05%, respectively. When the threshold of genetic distance was set to 1%, 20 molecular clusters were formed in 69 cases, with a clustering rate of 45.39%. Using the molecular network constituted by reported HIV/AIDS cases in 2020 as the baseline network, there were 2 active molecular clusters with ≥5 new cases in 2022, each with 9 cases, characterized mainly by individuals aged 50 or above, with a junior high school education or below, and transmission through commercial heterosexual sex. Conclusions The predominant HIV-1 subtypes among HIV/AIDS cases in Zhoushan City are CRF07_BC and CRF01_AE. Transmission through commercial heterosexual contact among middle-aged and elderly people is a main mode of HIV transmission.

Objective: To explore the effects of different concentrations of glucose solution on the survival of Aedes albopictus and Culex pipiens pallens larvae, the attraction to mosquitoes and egg-laying behaviors, so as to provide the reference for developing mosquito control technology based on sugar bait. Methods: White porcelain bowls were filled with 100 mL of 3%, 5%, 8%, 10% and 15% glucose solutions. Ten of fourth instar larvae of Aedes albopictus or Culex pipiens pallens were added to each bowl, and the survival of larvae was recorded after 2, 4, 6, 24, 48 and 72 hours. Egg-laying cups containing 5%, 8% and 15% glucose solution were put in mosquito cages containing fully blooded female mosquitoes of Aedes albopictus and Culex pipiens pallens (50 mosquitoes each), and the total number of eggs laid in 72 hours was observed. The analogous site room was filled with fully blooded and starved female mosquitoes of Aedes albopictus and Culex pipiens pallens (100 mosquitoes each), and simple mosquito control buckets containing 5% and 8% glucose solution and black sticky insect plates. The number of mosquitoes and eggs was observed after 6 days. All the above experiments were repeated 3 times using dechlorinated water as the control. Results: The 72 hour corrected mortality rates of Aedes albopictus and Culex pipiens pallens larvae gradually increased with the increase of glucose concentration. The glucose solution with 5% and higher concentrations was not suitable for mosquito larvae to survive. The attraction of egg-laying behaviors to Aedes albopictus and Culex pipiens pallens gradually decreased with the increase of glucose concentration. The effects were similar between 5% and 8% glucose solution, with the averages of 686.67 and 682.33 eggs for Aedes albopictus, and 3.00 and 2.33 egg rafts for Culex pipiens pallens. In analogous site room, there were 93.33, 105.00 and 130.33 adult mosquitoes captured on average in the control group, 5% and 8% glucose solution groups, respectively, with 8% glucose solution group more attractive to adult mosquitoes than the control group (F=3.283, P=0.030); there were 70.33, 55.33 and 63.00 Aedes albopictus eggs (eggs counts+larvae counts) on average, respectively, with statistically significant differences among the three groups (H=6.761, P=0.034). Conclusion Glucose solution with concentration of 5% or higher can effectively inhibit the survival of Aedes albopictus and Culex pipiens pallens larvae, and attractive to adult mosquitoes and egg-laying behavoirs.

Objective:To detect the prevalence of mosaic loss of chromosome Y in adult men in ten study areas in China, describe the epidemiological distribution of mosaic loss of chromosome Y (mLOY) carriers and assess its prospective association with lung cancer.Methods:Based on the data from baseline survey, genetic analysis and follow-up (as of December 31, 2018) from China Kadoorie Biobank, we used Mosaic Chromosomal Alterations pipeline to detect mLOY carriers in 10 areas in China and described the epidemiological characteristics of mLOY carriers in adult men, including age, area distribution, lifestyle and disease history. We used multivariate logistic regression model to identify the potential relevant factor of mLOY. Cox proportional hazard regression model was fitted to assess the prospective association of mLOY with lung cancer. Stratification analysis were conducted to evaluate the potential modification effects of smoking and age. We also conducted mediation analysis to assess the mediating effect of mLOY in the association between smoking and lung cancer.Results:A total of 42 859 adult men were included in our analysis, in whom 2 458 mLOY carriers were detected (5.7%). The detection rate increased with age ( P<0.05). The detection rate was higher in urban area (7.3%±0.2%) than that in rural area (4.7%±0.1%). The results of logistic regression analysis indicated that smoking might be a risk factor for the detection of mLOY ( OR=1.49, 95% CI:1.36-1.64). After follow-up for average 11.1 years, 1 041 lung cancer cases were observed. The prospective analysis showed that mLOY carriers had an increased risk for lung cancer by 24% compared with non-mLOY carriers ( HR=1.24, 95% CI:1.01-1.52) and expanded mLOY carriers (mLOY cell proportion ≥10%) had an increased risk for lung cancer by 50% ( HR=1.50, 95% CI:1.13-2.00). Stratification analysis showed no modification effects of smoking and age in the association between mLOY and lung cancer (interaction P>0.05). Mediation analysis showed that mLOY could be a mediating factor in the association between smoking and lung cancer, the estimated effect was 0.09 (0.01-0.17). Conclusions:There were significant differences in the detection rate of mLOY in adult men with different social-economic characteristics and lifestyles in ten areas in China. Besides, mLOY carriers, especially expanded mLOY carriers, had increased risk for lung cancer and mLOY might be a mediating factor in the association between smoking and lung cancer.
