OBJECTIVE To investigate ameliorative effects and mechanisms of two probiotics （Bacillus subtilis， Lactobacillus acidophilus） combined with Aurantii Fructus Immaturus （AFI） on functional dyspepsia （FD） in rats. METHODS Rats were randomly divided into blank group， model group， positive control group （domperidone group， 2.7 mg/kg）， AFI group （9 g/kg）， L. acidophilus group （5×107 cfu/kg）， B. subtilis group （5×107 cfu/kg）， L. acidophilus+ AFI group （L. acidophilus 5×107 cfu/kg+ AFI 9 g/kg）， and B. subtilis+AFI group （B. subtilis 5×107 cfu/kg+AFI 9 g/kg）， with 8 rats in each group. Except for the blank group， FD model was established by tail-clamping stimulation+hunger and satiety disorder+swimming exhaustion in other groups. After modeling， each group was given the corresponding drug/probiotic suspensions/physiological saline intragastrically， once a day， for 14 consecutive days. After the last medication， gastric emptying rate and the rate of propulsion of the small intestine in rats were measured； the levels of brain-gut peptide-related indicators [gastrin （GAS）， substance P （SP）， vasoactive intestinal peptide （VIP）， somatostatin （SS） and cholecystokinin （CCK）] in the serum of rats were measured. The pathological morphology of the gastric antrum tissue and duodenal tissue was observed. Cecal contents from the rats were collected for gut microbiota sequencing analysis. The protein expression levels of tyrosine kinase receptor c-Kit and stem cell factor （SCF） in the gastric antrum tissue， as well as Toll-like receptor 4 （TLR4）， myeloid differentiation factor 88 （MyD88）， and nuclear factor κB （NF-κB） in the duodenal tissue of the rats were detected. RESULTS Compared with the blank group， model group showed significantly lower gastric emptying rate， small intestinal propulsion rate， serum levels of GAS and SP， relative abundance of Firmicutes， Ace， Chao and Sobs indexes of the gut microbiota， and protein levels of SCF and c-Kit in gastric antrum （P＜0.05）， while serum levels of VIP， SS and CCK， relative abundance of Bacteroidetes， as well as protein expressions of TLR4， MyD88， and NF-κB， were significantly higher （P＜0.05）. The histological structure JZYC23S53） of the gastric antrum tissue appeared basically normal； however， abnormalities were observed in the duodenal structure， with a significant infiltration of inflammatory cells visible. Compared with the model group， all treatment groups significantly modulated most of the above indexes （P＜0.05）. The histological structure of the gastric antrum tissue was normal. Except for the B. subtilis group and the B. subtilis+AFI group， the pathological states of the duodenum in the remaining rats gradually recovered. Compared with each single drug group， most of above indexes in rats from each combination group showed further improvement （P＜0.05）. CONCLUSIONS The combination of AFI with two probiotics can improve gastrointestinal motility in FD rats， and the effect is superior to that of using the drugs alone. The specific underlying mechanisms may be related to the activation of the SCF/c-Kit signaling pathway and the inhibition of the TLR4/MyD88/NF-κB signaling pathway.

Objective: To investigate the Alzheimer's disease (AD) influencing factors among the elderly, so as to provide a basis for early prevention and intervention. Methods: From March to June 2024, participants aged 60 years and above from a sub-district in Haishu District, Ningbo City, Zhejiang Province were selected using a convenience sampling method. Data on demographics, lifestyle, and health status were collected through questionnaire surveys. Depressive symptoms were evaluated using the short-form Geriatric Depression Scale. The Chinese Mini-Mental State Examination (MMSE) was used for the initial screening of AD, and individuals who screened positive were further diagnosed by psychiatrists. Factors affecting AD among the elderly were analyzed using a multivariable logistic regression model. Results: A total of 3 644 individuals were surveyed, comprising 1 526 males (41.88%) and 2 118 females (58.12%). The mean age was (71.85±7.44) years. AD was detected in 200 cases, with a detection rate of 5.49%. Multivariable logistic regression analysis showed that individuals aged ≥65 years (65-<70 years, OR=3.012, 95%CI: 1.007-9.012; 70-<75 years, OR=3.131, 95%CI: 1.059-9.260; 75-<80 years, OR=5.779, 95%CI: 1.989-16.784; ≥80 years, OR=16.810, 95%CI: 5.926-47.685), those who were unmarried, divorced, or widowed (OR=1.973, 95%CI: 1.383-2.815), those with hearing loss (OR=1.573, 95%CI: 1.128-2.193), those with diabetes mellitus (OR=1.958, 95%CI: 1.362-2.814), and those with depressive symptoms (OR=4.143, 95%CI: 2.997-5.728) had a higher risk of AD. Conversely, individuals with an educational level of primary school or above (primary school, OR=0.579, 95%CI: 0.401-0.835; junior high school or above, OR=0.438, 95%CI: 0.259-0.741), and those who engaged in regular physical exercise (OR=0.414, 95%CI: 0.264-0.649) had a lower risk of AD. Conclusions The detection rate of AD was relatively high among the elderly in Haishu District. AD among the elderly was related to age, educational level, marital status, physical exercise, hearing loss, diabetes mellitus, and depressive symptoms.

Objective:To exploring the application effect of doctors-nurses-patients theory of goal attainment combined with StMarys cluster intervention mode in patients with tracheotomy after stroke.Methods:Using convenient sampling method, a total of 130 stroke patients with tracheostomy who were admitted to Shangqiu First People's Hospital from August 2020 to February 2022 were selected as the research objects. The patients were divided into the control group and the observation group using the random number table method, with 65 cases in each group. The control group received routine nursing care, while the observation group applied doctors-nurses-patients theory of goal attainment combined with StMarys cluster nursing intervention mode on the basis of the control group. After intervention, scores of Self Rating Anxiety Scale (SAS) and Self Rating Depression Scale (SDS) and patient nursing satisfaction were compared between the two groups.Results:After intervention, the SAS and SDS scores of the observation group were lower than those of the control group, and the nursing satisfaction was higher than that of the control group, and the differences were statistically significant ( P<0.05) . Conclusions:The doctors-nurses-patients theory of goal attainment combined with StMarys cluster intervention mode can help improve the psychological state of patients and increase nursing satisfaction.

The effect of Radix isatidis polysaccharide(IRPS)on TLR3/TRIF innate immune path-way and type Ⅰ interferon secretion in 3D4/21/CD163 cells infected by porcine reproductive and re-spiratory syndrome virus(PRRSV)was tested by Western blot and ELISA;moreover,the effect of IRPS on the immunosuppression infected by PRRSV was further verified with the TLR3 agonist poly(I∶C).The results showed that the protein levels of TLR3,TRIF,IRF3,IRF7 and type Ⅰ in-terferon secretion were significantly decreased at 18,24 h of PRRSV infection,while IRPS signifi-cantly inhibited this process;poly(I∶C)alleviated the protein levels of TRIF,IRF3 and IRF7 as well as the phosphorylation levels of IRF3 and IRF7 infected by PRRSV;at the same time,IRPS is synergistic with poly(I∶C).The results indicate that IRPS is able to alleviate immunosuppression caused by PRRSV infection via the TLR3/TRIF pathway.

The Pituitary Society released the 2023 International Consensus on the Diagnosis and Treatment of Prolactin-Secreting Adenomas, marking another update following the guidelines from the Endocrine Society in 2006 and 2011. Published in Nature Reviews Endocrinology, this consensus is based on the latest research evidence in recent years, covering topics such as the efficacy, long-term adverse effects, and withdrawal protocols of dopamine receptor agonists, as well as indications for surgery, preoperative medical therapy, and radiation therapy. It comprehensively discusses the treatment of prolactin-secreting adenomas in special periods and conditions. This article provides a detailed interpretation of the core recommended points in the consensus, focusing on four major aspects: diagnosis, treatment, special populations, and rare conditions of prolactinoma, aiming to help clinicians gain a comprehensive understanding of the consensus and provide assistance in clinical management.

Objective:To summarize experience of managing adult Langerhans cell histiocytosis(LCH) in hypothalamic-pituitary region(HPR) from Shanghai Huashan Hospital.Methods:Adult HPR-LCH patients diagnosed at oar endocrinology department from January 2013 to February 2022 were included. Clinical characteristics and treatment response were retrospectively analyzed.Results:A total of 27 adult HPR-LCH patients were included, with 14 cases involving the hypothalamus(H group) and 13 cases without(group NH). The common radiological findings included thickening of the pituitary stalk(25/27, 92.6%). At the time of diagnosis, 14 cases(51.9%) presented with panhypopituitarism, and 19 cases(70.4%) exhibited metabolic abnormalities. The group H had higher proportions of adrenal insufficiency, central hypothyroidism, panhypopituitarism, and diabetes compared to group NH(78.6% vs 23.1%; 78.6% vs 23.1%; 92.9% vs 30.8%, 35.7% vs 0%, respectively, all P<0.05). Hypothalamus syndrome was identified in 71.4%(10/14) of group H. The inital diagnosis rate was 79.2%(19/24), with 48.1% and 51.9% through biopsy of sellar and extrasellar lesions, respectively. Repeated biopsies confirmed the diagnosis in 25.9%(7/27) of cases. The peripheral lesions included bone, thyroid, lung, lymph node, thymus and liver. Out of 20 cases treated with chemotherapy, the objective response rate was 85% at 12 weeks. Four cases received local therapy, one case received traditional Chinese medicine treatment, one case abandoned treatment, and one case was lost to follow-up. The median follow-up time was 28(range 15 to 54) months. During this period, there were 3 deaths in group H and 1 death in group NH. Conclusion:Adult HPR-LCH patients presented with diabetes insipidus and high prevalences of hypopituitarism, hypothalamus syndrome and metabolic abnormalities. Typical imaging features were pituitary stalk thickening. A solitary mass in the HPR was usually very small, posing a great challenge for early diagnosis. Systemic evaluation would help to clarify the diagnosis. Patients with hypothalamus involvement had a higher mortality rate, suggesting the hypothalamus as a risk organ with poor prognosis.

Objective:To investigate the incidence and prothrombotic risk factors of postoperative venous thromboembolism(VTE) in Cushing′s disease and to further develop an assessment model to identify those at high risk of postoperative VTE events.Methods:A retrospective study was performed in 82 patients who were admitted to Huashan Hospital, Fudan University during January 2019 and January 2020 and diagnosed with Cushing′s disease. These patients underwent the evaluation about their clinical, hormonal, and coagulation parameters, as well as ultrasonography and pulmonary angio-CT when necessary. The least absolute shrinkage and selection operator(LASSO) regression analysis was used to screen independent risk factors, and a nomogram model for postsurgical VTE risk assessment in Cushing′s disease was initially established, and Bootstrap method was used for internal verification. Finally, the predictive model was evaluated for calibration and clinical applicability in the study cohort.Results:Nineteen patients(23.17%) developed VTE events, with 14 cases occurring after endoscopic transsphenoidal surgery. Compared to patients without VTE, those in the VTE group were older( P<0.001), had longer postoperative bed rest, higher rates of current infection, higher HbA 1C levels, and more severe glucose tolerance impairment(all P<0.05). Through LASSO regression analysis, two independent risk factors for postoperative VTE were identified: Age and current infection. Then a VTE risk assessment nomogram model was established to predict the patients at high risk of VTE. In the nomogram model for VTE risk assessment, the area under the receiver operating characteristic curve was 0.868(95% CI 0.787-0.949), with the calibration curve closely aligning with the ideal diagonal line and the clinical decision curve exceeding the two extreme curves. Conclusions:Advanced perioperative assessment needs to be taken to screen those with high VTE risks in patients diagnosed with Cushing′s disease. Additionally, during the perioperative period, patients with Cushing′s disease should undergo mandatory physical activity or prophylactic anticoagulant therapy.

Renal cell carcinoma is a common malignant tumor in urinary system with poor prognosis, and the advanced patients are prone to distant metastases such as bone, brain and lung. Common treatment modalities for renal cell carcinoma include surgery, radiotherapy, immunotherapy and targeted therapy. Tumor microenvironment plays an important role in the occurrence, pathophysiological process and treatment of renal cell carcinoma. The study of tumor microenvironment characteristics has led to significant advances in the treatment of renal cell carcinoma. At present, immunotherapy and cell therapy for renal cancer can effectively prolong the survival of patients and provide new treatment methods for patients with advanced renal cell carcinoma.
