ObjectiveTo study the clinical characteristics and influencing factors of rheumatoid arthritis （RA） in the patients with cold dampness obstruction syndrome. MethodsThe RA patients treated in the Department of Traditional Chinese Medicine and Rheumatology of the China-Japan Friendship Hospital from August 2022 to June 2024 were selected. The demographic information， clinical data， laboratory test results， and traditional Chinese medicine （TCM） symptom information were collected for syndrome differentiation， on the basis of which the characteristics and influencing factors of cold dampness obstruction syndrome were analyzed. ResultsA total of 258 RA patients were selected in this study， including 88 （34.1%） patients with cold dampness obstruction syndrome， 53 （20.5%） patients with dampness and heat obstruction syndrome， 31 （12.0%） patients with wind dampness obstruction syndrome， 29 （11.2%） patients with liver-kidney deficiency syndrome， 19 （7.4%） patients with Qi-blood deficiency syndrome， 14 （5.4%） patients with phlegm-stasis obstruction syndrome， 15 （5.8%） patients with stasis obstructing collateral syndrome and 9 （3.5%） patients with Qi-Yin deficiency syndrome. The patients were assigned into two groups of cold dampness obstruction syndrome and other syndromes. The group of cold dampness obstruction syndrome had lower joint fever， 28-tender joint count （TJC28）， and 28-joint disease activity score （DAS28）-C-reactive protein （CRP） and higher central sensitization， cold feeling of joints， fear of wind and cold， cold limbs， and abdominal distention than the group of other syndromes （P<0.05）. The binary logistic regression analysis showed that central sensitization （OR 5.749， 95%CI 2.116-15.616， P<0.001） and DAS28-CRP （OR 0.600， 95% CI 0.418-0.862， P=0.006） were the independent factors influencing cold dampness obstruction syndrome in RA. ConclusionCold dampness obstruction syndrome is a common syndrome in RA patients. It is associated with central sensitization， cold feeling of joints， abdominal distension and may be a clinical syndrome associated with central sensitization.

Objective:To investigate microbial ecology in restored milk (RM) -donor human milk (DHM) supplemented with mother's own milk (MOM)-under varying MOM ratios, incubation temperatures, and durations. Methods:This in vitro controlled study utilized breast milk samples collected from mothers of preterm infants (<37 weeks) admitted to the Neonatal Intensive Care Unit of Chongqing Health Center for Women and Children between December 2024 and March 2025, including five MOM samples and one DHM sample. Each MOM sample was mixed with DHM at 10% (RM-10 group) or 30% (RM-30 group) volume ratios. Samples were incubated at room temperature (23-26 ℃) and 37 ℃ for 1 h and 4 h, followed by collection. Microbial α-diversity (Chao/Shannon indices), β-diversity (principal co-ordinates analysis), and taxonomic composition (phylum/genus) were analyzed via high-throughput sequencing. Statistical analysis included analysis of variance and the Kruskal-Wallis H test. Results:No statistically significant differences in the Chao index or Shannon index were observed between the RM-10 and RM-30 groups across different incubation times and temperatures ( H or F values=7.61 and 93.20, respectively; both P>0.05). At 37 ℃, the microbial composition of the RM-30 group at both 1 h and 4 h showed no significant difference compared to the initial MOM samples ( R=－0.018, P=0.540), with Firmicutes abundance restored to 65%-90% of the initial MOM level. At room temperature, incubation of the RM-30 group partially restored microbial communities (50%-60%), but induced overgrowth of Proteobacteria (e.g., Pseudomonas, Acinetobacter). Incubation of the RM-10 group at 37 ℃ for 1 h and 4 h also showed no significant difference in microbial composition compared to the initial MOM ( R=－0.004, P=0.442). However, at room temperature, Proteobacteria consistently increased in the RM-10 group samples, and significant differences in microbial composition compared to initial MOM were observed at both 1 h and 4 h ( R=0.179, P=0.027). Conclusion:Under the experimental conditions of this study, preliminary evidence suggests that incubating a blend of DHM and 30% MOM at 37 ℃ for 1 h or 4 h may modulate the microbial composition toward a potentially beneficial profile.

Objective:With the aggravation of population aging, the burden of malignant tumors in the elderly population is becoming more and more heavy. This study aims to analyze the incidence and mortality of malignant tumors in the elderly population in Hebei Province in the past decade.Methods:The incidence and mortality data of malignant tumors in people aged ≥60 years old in 38 cancer registration areas in Hebei Province from 2011 to 2020 were collected, and the incidence and mortality were analyzed by gender, urban and rural areas, and age groups. The age standardized rates were calculated using the 2000 Chinese population census and Segi′s world population. The trend of incidence and mortality was analyzed using the Joinpoint model and the average annual percent change (AAPC).Results:From 2011 to 2020, 216 200 new cases of malignant tumors were reported in the elderly population in the cancer registration areas of Hebei Province, and 170 700 deaths were reported. The peak ages of incident cases number for males and females were 65-69 years old and 60-64 years old, respectively. The crude incidence rate of malignant tumors in the elderly was 905.42/10 5, and the crude mortality rate was 714.96/10 5. In general, the incidence and mortality in rural areas were higher than those in urban areas, and the incidence and mortality in males were higher than those in females. The peak ages of incidence and mortality were 80-84 years old and 85+ years old, respectively. From 2011 to 2020, lung cancer, gastric cancer, esophageal cancer, female breast cancer, and colorectal cancer were the main malignant tumors of incidence rate in the elderly population in Hebei Province, and lung cancer, gastric cancer, liver cancer, esophageal cancer, and colorectal cancer were the main malignant tumors in the mortality rate. From 2011 to 2020, the incidence and mortality of malignant tumors in the elderly population in Hebei Province showed a decreasing trend, and AAPC for the age-standardized incidence and mortality were -4.69% and -5.53%, respectively. The rank of incidence and mortality rate of each cancer had changed, but the top two were still lung cancer and stomach cancer. Conclusions:The incidence and mortality of cancer in the elderly population in Hebei province have decreased, but the burden is still heavy. Lung cancer and stomach cancer are still the focus of prevention and treatment in the elderly population in Hebei province.

Objective:To understand the burden of cancer disease in Hebei Province in recent years and to analyze the change trend of cancer in Hebei Province from 2011 to 2020.Methods:The incidence and death data of cancer were collected from 38 cancer registries in Hebei Province during 2011-2020. The incidence (mortality) rate, standardized incidence (mortality) rate and composition ratio of each region, sex, and age were calculated respectively, and the incidence and death of major cancers in our province were summarized. The age-standardized morbidity (mortality) rates of China and the world population were calculated using the 2000 China standard population composition and Segi's world population composition respectively. Trend analysis of morbidity and mortality was performed and average annual percentage change (AAPC) was calculated.Results:In 2020, the crude cancer incidence rate and the age-standardized morbidity rate of China was 229.36/100 000 and 147.06/100 000, respectively. An estimated 171 600 new cases were reported in the province. The crude cancer mortality rate and the age-standardized mortality rates of China was 146.38/100 000 and 85.33/100 000. The estimated number of deaths in the province is 108 900. In the cancer registration areas of Hebei Province, 84% of all cancer patients occurred in people 50 years of age and older. From 2011 to 2020, the incidence and mortality of cancer in Hebei Province showed a decreasing trend. The AAPC was -4.2% ( P＜0.001), which decreased from 206.61/100 000 in 2011 to 143.74/100 000 in 2020. The world standard mortality rate of cancer was 147.69/100 000 in 2011, and decreased to 84.79/100 000 in 2020. The AAPC was -5.7% ( P＜0.001). The world-standard incidence and mortality of lung cancer, esophageal cancer, gastric cancer, liver cancer and colorectal cancer decreased from 2011 to 2020. The AAPCs of the world-standard incidence were -4.0%, -12.3%, -9.4%, -6.0% and -1.6%, respectively. The AAPCs of the world-standard mortality were -4.9%, -11.3%, -8.5%, -5.7% and -3.3%, which were statistically significant. The incidence of thyroid cancer increased rapidly, the AAPC of which was 9.7% ( P＜0.001). The rates of female breast cancer and male prostate cancer in Hebei Province were stable. Conclusions:The world-standard incidence and mortality of cancer in Hebei Provincial cancer registries areas show a downward trend from 2011 to 2020. However, the cancer incidence and mortality in Hebei Province are still at high levels. It's necessary to strengthen cancer prevention and control in Hebei Province, improve the awareness of cancer prevention and control in the whole society, and promote the concept of tertiary cancer prevention to reduce the cancer burden in Hebei Province.

Objective:To conduct a Meta-synthesis on the characteristics of symptom help-seeking behavior in adult cancer patients, so as to provide evidence-based guidance for early intervention of symptom help-seeking behavior in cancer patients in China.Methods:Qualitative studies on symptom help-seeking behavioral characteristics of cancer patients were systematically searched in PubMed, Cochrane Library, Web of Science, ProQuest, Nature, ScienceDirect, China National Knowledge Infrastructure, WanFang Data, China Biology Medicine disc, and VIP. The search period was from database establishment to December 31, 2024. Included literature was independently evaluated using the Australian Joanna Briggs Institute Center for Evidence-Based Health Care Quality Assessment Criteria for Qualitative Research. The results were integrated through the Meta-synthesis method.Results:A total of 15 papers were included, and 30 findings were distilled and grouped into nine categories, resulting in three integrated findings of low symptom perception and interpretation bias, coping styles of symptom disclosure, and factors influencing symptom help-seeking behaviors.Conclusions:Symptom help-seeking behaviors of cancer patients are influenced by a variety of factors, and understanding their behavioral characteristics is useful in informing the development of intervention strategies.

Childhood cataract is a disease that affects the development of children's vision. It is divided into infants and adolescents according to the age of onset. Surgery is the main treatment, but the vision after surgery is difficult to reach the level of healthy children. Macular dysplasia is an important factor affecting postoperative visual acuity. In recent years, with the development of optical coherence tomography and optical coherence tomography angiography, more and more research has been done on macular development of children's cataract. The retinal structure in the macular area of children with cataract is abnormal, and the early inflammatory reaction after surgery can also lead to structural changes. In addition, insufficient blood supply to the macular area may affect retinal structure and function. The mechanism by which childhood cataract affects macular structure is still unclear and needs further study. Understanding the relationship between macular structure and vision prognosis is helpful to develop more effective treatment and improve the vision prognosis of children.

Objective:To explore the clinical characteristics of adult mediastinal bronchial cysts complicated with aspergillus infection, aiming to improve clinicians′ understanding of this rare lesion.Methods:A case of adult mediastinal bronchial cyst with aspergillus infection admitted to the Foshan Second People′s Hospital in February 2024, mainly presenting with fever and chest pain, was reported. Chest CT showed a mediastinal mass, and postoperative pathology confirmed bronchial cyst with aspergillus infection. Combined with relevant literature review, the clinical features, diagnosis and treatment points of the disease were summarized.Results:The patient successfully underwent surgical resection of the lesion, and pathological examination confirmed the diagnosis of bronchial cyst complicated with aspergillus infection. Literature review indicated that mediastinal bronchial cysts are relatively rare in adults, and cases complicated with aspergillus infection are even rarer.Conclusions:Adult mediastinal bronchial cyst complicated with aspergillus infection is a rare lesion with non-specific clinical manifestations. Imaging examination is an important diagnostic method, and the final diagnosis depends on pathological examination. Enhancing clinicians′ awareness of this disease is helpful for timely and accurate diagnosis and reasonable treatment.

Objective To analyze the mechanisms of meaning in life and living arrangements impacting the effect of activities of dai-ly living(ADL)on depression for older adults.Methods From September to November,2024,community-dwelling older adults from Weifang,Shandong,were investi-gated with questionnaire using Basic Activities of Daily Living Scale(BADL),Meaning in Life Questionnaire(MLQ),Geriatric Depression Scale(GDS),and a general information questionnaire including living arrange-ments.Results A total of 256 questionnaires were distributed,and 245 valid questionnaires were returned.There were signifi-cant differences in GDS scores among older adults with different personal monthly incomes and living arrange-ments(F>3.744,P<0.05).BADL scores were positively correlated with GDS scores(r=0.490,P<0.001)and negatively correlated with MLQ scores(r=-0.370,P<0.001),and MLQ scores were negatively correlated with GDS scores(r=-0.369,P<0.001).There was significant direct effect of BADL scores on GDS scores(effect=1.128,95%CI 0.829～1.427),and mediating effect of MLQ scores on the relationship between BADL and GDS scores(effect=0.171,95%CI 0.028～0.337).The moderating effect of living alone was significant(|B|=0.127,|t|=2.103,P<0.05)on the association between MLQ and GDS,compared with intergenerational coresidence.Conclusion Meaning in life partially mediates the association between ADL and depression in older adults,especially for those living alone.
