Objective To investigate the dietary patterns of rural residents in the high-incidence areas of esophageal cancer (EC), and to explore the clustering and influencing factors of risk factors associated with high-incidence characteristics. Methods A special structured questionnaire was applied to conduct a face-to-face survey on the dietary patterns of rural residents in Yanting county of Sichuan Province from July to August 2021. Univariate and multivariate logistic regression models were used to analyze the influencing factors of risk factor clustering for EC. Results There were 838 valid questionnaires in this study. A total of 90.8% of rural residents used clean water such as tap water. In the past one year, the people who ate fruits and vegetables, soybean products, onions and garlic in high frequency accounted for 69.5%, 32.8% and 74.5%, respectively; the people who ate kimchi, pickled vegetables, sauerkraut, barbecue, hot food and mildew food in low frequency accounted for 59.2%, 79.6%, 68.2%, 90.3%, 80.9% and 90.3%, respectively. The clustering of risk factors for EC was found in 73.3% of residents, and the aggregation of two risk factors was the most common mode (28.2%), among which tumor history and preserved food was the main clustering pattern (4.6%). The logistic regression model revealed that the gender, age, marital status and occupation were independent influencing factors for the risk factors clustering of EC (P<0.05). Conclusion A majority of rural residents in high-incidence areas of EC in Yanting county have good eating habits, but the clustering of some risk factors is still at a high level. Gender, age, marital status, and occupation are influencing factors of the risk factors clustering of EC.

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.

Objectives: . We aimed to develop a new calculation model for calcium requirements in dialysis patients following parathyroidectomy. Methods: . A total of 98 patients with secondary hyperparathyroidism receiving parathyroidectomy from January 2014 to January 2022 were enrolled in this study. Among these patients, 78 were randomly selected for construction of the calcium requirement calculation model, and the remaining 20 patients were selected for model validation. The calcium requirement model estimated the total calcium supplementation for 1 week after surgery using variables with significant relationships in the derivation group by stepwise multiple linear regression analysis. Bias, precision, and accuracy were measured in the validation group to determine the performance of the model. Results: . The model was as follows: calcium requirement for 1 week after surgery=33.798–8.929×immediate postoperative calcium+0.190×C-reactive protein–0.125×age+0.002×preoperative intact parathyroid hormone+0.003×preoperative alkaline phosphatase (R2=0.8). The model was successfully validated. Conclusion . We generated a novel model to guide calcium supplementation. This model can assist in stabilizing the serum calcium levels of patients during the early postoperative period. Furthermore, it contributes to the individualized and precise treatment of hypocalcemia in patients following parathyroidectomy.

ObjectiveTo observe the intervention effect of artesunate （ART） and Qingfei Paidu decoction （QFPD） on the mouse model of cytokine storm （CS） induced by viral mimic Poly （I∶C）. MethodEighty-four SPF male BALB/c mice were randomly divided into seven groups， with 12 mice in each group. Mice， except for those in the blank group （n=12）， were subjected to CS model induction by tail vein injection of Poly （I∶C） at 15 mg·kg^-1， followed by drug treatments of low-dose ART （ART-l， 10 mg·kg^-1）， medium-dose ART （ART-m， 20 mg·kg^-1）， high-dose ART （ART-h， 40 mg·kg^-1）， Qingfei Paidu Decoction （QFPD， 2.4 g·kg^-1）， and dexamethasone （DXM， 10 mg·kg^-1）. After 6 hours， lung tissues， bronchoalveolar lavage fluid （BALF）， spleen， lung， and peripheral blood were collected. The lung and spleen indexes were calculated and the number of inflammatory cells in BALF was detected. The pathological changes in lung tissues were observed by hematoxylin-eosin （HE） staining and the levels of tumor necrosis factor-α （TNF-α）， interferon-γ （IFN-γ）， interleukin-1β （IL-1β）， and IL-6 in BALF were detected by enzyme-linked immunosorbent assay （ELISA）. The expression of immune cells in BALF and peripheral blood was detected by flow cytometry. ResultThe analysis of lung and spleen indexes showed that compared with the blank group， the model group showed increased lung and spleen indexes to varying degrees （P<0.05）. Compared with the model group， the ART groups showed reduced spleen index （P<0.05） and the ART-l group showed reduced lung index （P<0.05）. Additionally， the QFPD group showed reduced lung and spleen indexes （P<0.05）. ELISA results showed that except for TNF-α， the levels of IFN-γ， IL-1β， and IL-6 in the model group increased compared with those in the blank group （P<0.05）. Compared with the model group， the ART-l group and the QFPD group showed reduced content of TNF-α （P<0.05）， and all groups with drug intervention showed reduced content of IFN-γ， IL-1β， and IL-6 （P<0.05）. The number of inflammatory cells in BALF showed a downward trend in the model group， and the number of cells increased in the groups with drug intervention except for the DXM group （P<0.05）. Flow cytometry showed that compared with the blank group， the model group showed decreased number of CD3 in the peripheral blood （P<0.05）， increased Ly-6G and F4/80 （P<0.05）， decreased expression of CD45， CD3， and F4/80 in BALF （P<0.05）， and increased expressions of Ly-6G （P<0.05）. Compared with the model group， the ART groups and QFPD group showed increased CD45 content in peripheral blood （P<0.05）， decreased Ly-6G and F4/80 content （P<0.05）， increased CD45 and F4/80 content in BALF （P<0.05）， and decreased expression of Ly-6G （P<0.05）. ConclusionART and QFPD have a good protective effect on Poly （I∶C）-induced CS in mice， and the mechanism is related to the effective intervention in immune cell disorder.

Objective:To explore the risk factors of hypocalcemia and the correlation between calcium supplementation and clinical parameters after parathyroidectomy (PTX) in maintenance hemodialysis patients with secondary hyperparathyroidism (SHPT), and to analyze the effect of calcium supplementation after PTX on the long-term prognosis of patients.Methods:This study was a single-center retrospective study. The patients who underwent PTX in maintenance hemodialysis patients with SHPT in the Huashan Hospital affiliated to Fudan University from October 2014 to March 2021 were retrospectively enrolled. Total PTX with auto transplantation or total PTX alone were the surgical procedures. According to the postoperative requirement of calcium in the first week, the patients were divided into two groups: high calcium supplement (>16.05 g/week) group and low calcium supplement group (≤16.05 g/week). According to the average serum calcium level in the first week after operation, the patients were divided into hypocalcemia group (≤2.1 mmol/L) and non-hypocalcemia group (>2.1 mmol/L) and the differences of clinical parameters between the two groups were compared. The correlation between clinical parameters and the postoperative calcium requirement was examined through Pearson or Spearman correlation analysis. The influencing factors for hypocalcemia after PTX were examined through logistic regression analysis. The survival curve was made by Kaplan-Meier method, and the difference of cumulative survival rate between the two groups was compared by log-rank test.Results:A total of 98 maintenance hemodialysis patients with SHPT were enrolled. The levels of serum calcium, phosphorus, and intact parathyroid hormone (iPTH) after the operation decreased significantly than those of preoperation (all P<0.05). Multiple linear regression analysis showed age ( β=-0.160, P=0.030), iPTH ( β=0.004, P=0.025) and C-reactive protein ( β=0.186, P=0.011) were correlated with postoperative calcium requirement. Preoperative alkaline phosphatase ( OR=1.002, 95% CI 1.000-1.004, P=0.018) and hemoglobin ( OR=0.977, 95% CI 0.954-1.000, P=0.048) independently predicted the occurrence risk of postoperative hypocalcemia through multivariate logistic regression analysis. The recurrence rate of high calcium supplement group was higher than that of low calcium supplement group (10.26% vs 0, P=0.023) and there was no significant difference in all-cause mortality between the two groups (17.95% vs 5.08%, P=0.086). The recurrence rate between the hypocalcemia group and non-hypocalcemia group was no significantly different (8.3% vs 1.8%, P=0.451) and there was no significant difference in all cause mortality between the two groups (12.5% vs 12.7%, P=1.000). Kaplan-Meier survival curve showed that the cumulative survival rate between the two groups was no significantly different (log-rank test χ2=0.147, P=0.702). Conclusions:PTX is a safe and effective therapeutic method to reduce the level of iPTH and improve the metabolism of calcium and phosphorus in SHPT patients. Age, iPTH and C-reactive protein are correlated with the postoperative requirement of calcium in the first week. Preoperative alkaline phosphatase and hemoglobin are independent risk factors for postoperative hypocalcemia. Correcting preoperative electrolyte disorder, improving infection and anemia can reduce the incidence of hypocalcemia after PTX.

Objective:To acquire more scientific, accurate and efficient unplanned extubation (UEX) quality management data by using information technology to directly take the quality index data of unplanned extubation from the nursing medical record system.Methods:From June 2019 to August 2019, a knowledge base of pipeline management including the name of pipeline, pipeline evaluation, pipeline care measures, and reasons for unplanned extubation of pipeline was established in Sir Run Run Shaw Hospital Affiliated to Zhejiang University School of Medicine. Through the analysis of each node of pipeline management, pipeline management system was established. And the non-planned pipeline management data set was directly collected to the nursing quality management system for statistics and analysis, which was verified.Results:In clinical application from September 2019 to september 2020, the direct collection of unplanned extubation quality index data saved 496 hours of nursing labor costs per month, and the accuracy of direct data collection increased from 95.8% (161/168) in trial operation to 100.0% (494/494). The underreporting rate of adverse events decreased to 0. Satisfaction with the application of the quality index management system for unplanned extubation was (4.35 ± 0.73) points.Conclusions:The direct collection of quality index data for unplanned extubation improves the accuracy of the data. Nurses no longer need to report unplanned extubation incidents. The clinical nursing information system and the nursing management system are interconnected to improve the management efficiency of unplanned extubation. It is worthy of application and promotion in clinic.

In this article, we summarize clinical features and management of 3 cases with pathology confirmed granulomatous hypophysitis, to improve knowledge and provide treatment guidance in this regards. Patients presented with headache, blurred vision and central diabetes insipidus, respectively. The imaging manifestations were sellar area or pituitary stalk occupying lesions, and the nature was undetermined. The symptoms were not completely relieved after subtotal resection or biopsy. The symptoms could be controlled by high dose glucocorticoid, but relapsed after reduction. Two patients were treated with glucocorticoid combined with azathioprine. One case had no recurrence after withdrawal of the drug and 1 patient was still in treatment. Therefore, for the patients whose symptoms are still not relieved after operation and recurred after glucocorticoid reduction, the scheme of high-dose glucocorticoid combined with immunosuppressant azathioprine can be considered, which may achieve satisfactory curative effect and prognosis.

Objective:To explore the characteristics and differences of oxygenated hemoglobin responses in different brain regions in adolescent depressive disorder patients and healthy adolescents during speech fluency task based on functional near-infrared spectroscopy imaging.Methods:From March 2021 to June 2021, twenty-nine adolescents with depression(depressed group) and 26 healthy adolescents(normal group) were enrolled. The severity of depression was assessed by Hamilton depression scale, and the speech fluency task was performed by functional near-infrared spectroscopy brain imaging, and the relative concentrations of oxyhemoglobin in the prefrontal and bilateral temporal lobes were measured.SPSS 26.0 statistical software was used for data analysis, chi-square test was used for gender count data. The t-test was used for comparison of two groups. The measurement data that did not conform to normal distribution were compared between the two groups by Mann-Whitney U test. Results:In the speech fluency task, there was no significant difference in the concentration of oxygenated hemoglobin in prefrontal and left temporal between the depressed group and the normal group (both P>0.05); the oxygenated hemoglobin concentration in the right temporal lobe(-9.179(-22.231, 4.789)) of depressed group was significantly lower than that of the normal group (12.754(-9.438, 35.008)), and the difference was statistically significant ( U=538.00, P<0.05). The oxygenated hemoglobin concentration in right temporal lobe of depressed group had no correlation with the score of Hamilton depression rating scale ( r=0.092, P>0.05). Conclusion:The right temporal lobe function of adolescent depression patients is lower than that of healthy controls during speech fluency tasks, which provides a basis for study of the relationship between depression and some cognitive sensitivity impairment and the function of right temporal lobe.

To develop a quality control checklist for the prevention and control of coronavirus disease 2019 （COVID-19） in fever clinic and isolation ward of the general hospital and to assess its application. Based on the relevant prevention and control plans and technical guidelines for COVID-19，Delphi method was used to identity items for evaluation，and a quality control checklist for the prevention and control of COVID-19 in the fever clinic and isolation ward was developed in Sir Run Run Shaw Hospital. The checklists included 8 dimensions and 32 items for fever clinic，7 dimensions and 27 items for the isolation ward. The appointed inspectors conducted daily quality control for each shift with this checklist. The expert authority coefficient was 0.88，the mean of the importance of each index in the quality control table was not less than 4.8，and the coefficient of variation was not more than 0.07. During the entire February 2020，8 problems were found and rectified on-the-spot with the application of the checklist. Quality inspection rate was 100% in both isolation wards and fever clinic. The compliance rate and accuracy rate of hand hygiene were 100%; the correct rate of wearing and removing protective equipment increased from 96% to 100%. During the same period，a total of 1915 patients were admitted to the fever clinic，including 191 suspected patients （all were isolated in the hospital，3 were confirmed）. There were no medical staff infected with COVID-19，no cross infection of patients and their families in the hospital. A quality control checklist for the prevention and control of COVID-19 has been developed and applied in the isolation wards and fever clinic，which plays an important role in preventing nosocomial infection.

Objective:To investigate the effect of pidotimod in reducing pulmonary infection in patients with lung cancer undergoing chemotherapy.Methods:One hundred and twenty patients with lung cancer in the Fifth People′s Hospital of Dalian City from July 2017 to July 2018 were selected. The patients were divided into control group and pidotimod group by random digits table method with 60 cases each. The patients were treated with standard two drugs chemotherapy containing platinum drug according to the pathological type, and the patients in pidotimod group were combined with pidotimod. The number of pulmonary infections during chemotherapy, number of completed scheduled chemotherapy and adverse reaction were observed. The correlation between pulmonary infection and pidotimod was analyzed by multivariate orderly Logistic regression.Results:The incidence of pulmonary infection in pidotimod group was significantly lower than that in control group: 18.33% (11/60) vs. 40.00% (24/60), and there was statistical difference ( χ2 = 6.845, P<0.01). The rate of completed scheduled chemotherapy in pidotimod group was significantly higher than that in control group: 55.00% (33/60) vs. 36.67% (22/60), and there was statistical difference ( χ2 = 4.062, P<0.05). Multivariate orderly Logistic regression analysis result showed that pidotimod could reduce the risk of pulmonary infection ( OR = 0.210, 95% CI 0.072 to 0.606, P = 0.004), and help to complete the scheduled chemotherapy ( OR = 2.323, 95% CI 1.080 to 5.003, P = 0.031). In pidotimod group, no obvious adverse reaction related to pidotimod application was detected, and chemotherapy was not affected. Conclusions:Application of pidotimod can reduce the chance of pulmonary infection in patients with lung cancer undergoing chemotherapy and help patients complete scheduled chemotherapy.
