BACKGROUND: Epidemiological data on chronic diarrhea in the Chinese population are lacking, and the association between obesity and chronic diarrhea in East Asian populations remains inconclusive. This study aimed to investigate the prevalence of chronic diarrhea and its association with obesity in a representative community-dwelling Chinese population. METHODS: This cross-sectional study was based on a multistage, randomized cluster sampling involving 3503 residents aged 20-69 years from representative urban and rural communities in Beijing. Chronic diarrhea was assessed using the Bristol Stool Form Scale (BSFS), and obesity was determined based on body mass index (BMI). Logistic regression analysis and restricted cubic splines were used to evaluate the relationship between obesity and chronic diarrhea. RESULTS: The standardized prevalence of chronic diarrhea in the study population was 12.88%. The average BMI was 24.67 kg/m 2 . Of all the participants, 35.17% (1232/3503) of participants were classified as overweight and 16.13% (565/3503) as obese. After adjustment for potential confounders, individuals with obesity had an increased risk of chronic diarrhea as compared to normal weight individuals (odds ratio = 1.58, 95% confidence interval: 1.20-2.06). A nonlinear association between BMI and the risk of chronic diarrhea was observed in community residents of males and the overall participant group ( P  = 0.026 and 0.017, respectively). CONCLUSIONS This study presents initial findings on the prevalence of chronic diarrhea among residents of Chinese communities while offering substantiated evidence regarding the significant association between obesity and chronic diarrhea. These findings offer a novel perspective on gastrointestinal health management.

ObjectiveTo investigate the effects of Guizhi Jia Longgu Mulitang on the expression difference of interleukin-10 （IL-10） and tumor necrosis factor -α （TNF-α） in related organs of insomnia rats with sensory dysfunction dominated by lung and study the mechanism of Guizhi Jia Longgu Mulitang in improving insomnia. MethodSD rats were randomly divided into the blank group， model group， western medicine group， and traditional Chinese medicine （TCM） group， with 10 rats in each group. The rats were deprived of sleep by shallow water environment method in a long platform， and the modeling lasted for 42 d. The blank group and model group were given 0.05 mL·kg^-1 normal saline by gavage， and the western medicine group and TCM group were given drugs during modeling. To be specific， the western medicine group was given 0.105 mg·kg^-1 dexzopiclone tablet by gavage， while the TCM group was given 7 600 mg·kg^-1 Guizhi Jia Longgu Mulitang by gavage， both lasting for 28 days. After successful modeling， the Morris water maze experiment was performed on the 42nd day to detect the motion and spatial memory ability of rats. The levels of IL-10 and TNF-α in serum were detected by enzyme-linked immunosorbent assay （ELISA）. The protein expression of IL-10 and TNF-α in the lung and brain tissue of rats was detected by Western blot. The levels of IL-10 and TNF-α in the lung and brain tissue of rats were detected by immunohistochemistry. ResultCompared with the blank group， the sleep stages non-rapid eye movement ( NREM ) and rapid eye movement ( REM ) of the model group were significantly shortened （P<0.5， P<0.01）， and the wake stage was significantly increased （P<0.01）. The total time and distance of platform exploration were significantly increased （P<0.01）. In the target quadrant （the third quadrant）， the percentage of exploration time and the times of crossing the platform were significantly decreased （P<0.01）. ELISA results showed that the serum IL-10 level was significantly decreased （P<0.01）， and TNF-α level was significantly increased （P<0.01）. The results of Western blot showed that the protein expression of IL-10 in brain and lung tissue of rats was significantly decreased （P<0.01）， and the protein expression of TNF-α was significantly increased （P<0.01）. The results of immunohistochemistry showed that the expression of IL-10 in the brain and lung tissue of rats was significantly decreased （P<0.01）， and that of TNF-α was significantly increased （P<0.01）. Compared with the model group， the NREM stage and REM stage of the western medicine group and the TCM group were significantly increased （P<0.5， P<0.01）， and the wake stage was shortened （P<0.5）. The total time and distance of platform exploration were significantly decreased （P<0.01）. In the target quadrant （the third quadrant）， the percentage of exploration time and the times of crossing the platform were significantly increased （P<0.05， P<0.01）. The serum IL-10 level was significantly increased （P<0.01）， and the serum TNF-α level was significantly decreased according to the ELISA results （P<0.01）. The results of Western blot showed that the protein expression of IL-10 in brain tissue and lung tissue was significantly increased （P<0.01）， and the protein expression of TNF-α was significantly decreased （P<0.01）. The results of immunohistochemistry showed that the expression of IL-10 in brain tissue and lung tissue was significantly increased （P<0.05， P<0.01）， and the expression of TNF-α was significantly decreased （P<0.05， P<0.01）. ConclusionGuizhi Jia Longgu Mulitang can improve the expression of IL-10 and TNF-α in brain and lung tissue of insomnia rats with sensory dysfunction dominated by lung， prolong sleep time， and then improve insomnia. The mechanism may be related to improving the expression level of inflammatory factors.

Cognitive impairment is the most common non-motor symptom with the highest disability rate in patients with Parkinson disease(PD).PD patients often experience cognitive impairment and frailty with the increase in age and the progression of the disease,which can seriously affect their quality of life.However,the research on the association be-tween PD cognitive impairment(PD-CI)and frailty is still in the exploratory stage.This study reviews the association be-tween PD-CI and frailty,in order to enhance the understanding of clinical healthcare workers,provide early intervention opportunities for PD-CI patients,delay their progression to PD dementia,and improve their quality of life.

Colorectal cancer (CRC) is a prevalent malignant tumor often leading to liver metastasis and mortality. Despite some success with PD-1/PD-L1 immunotherapy, the response rate for colon cancer patients remains relatively low. This is closely related to the immunosuppressive tumor microenvironment mediated by tumor-associated macrophages (TAMs). Our previous work identified that a phosphoglycerate mutase 1 (PGAM1) allosteric inhibitor, HKB99, exerts a range of anti-tumor activities in lung cancer. Here, we found that upregulation of PGAM1 correlates with increased levels of M2-like tumor-associated macrophages (TAMs) in human colon cancer samples, particularly in liver metastatic tissues. HKB99 suppressed tumor growth and metastasis in cell culture and syngeneic tumor models. M2-polarization, induced by colon cancer cell co-culture, was reversed by HKB99. Conversely, the increased migration of colon cancer cells by M2-TAMs was remarkably restrained by HKB99. Notably, a decrease in TAM infiltration was required for the HKB99-mediated anti-tumor effect, along with an increase in CD8⁺ T cell infiltration. Moreover, HKB99 improved the efficacy of anti-PD-1 treatment in syngeneic tumors. Overall, this study highlights HKB99's inhibitory activity in TAM-mediated colon cancer progression. Targeting PGAM1 could lead to novel therapeutic strategies and enhance the effectiveness of existing immunotherapies for colon cancer.

Objective To analyze the efficacy and tolerance of methotrexate(MTX)in remission maintenance of Crohn′s disease (CD).Methods From June 2012 to August 2015 ,49 CD patients who received MTX as mainly treatment medication to maintain remission were enrolled.The pre-medication history,efficacy,dosage and side effects of MTX were analyzed.The effects of inducing strategy on disease recurrence were analyzed.Chi-square test and t test were used for statistical analysis.Results Among the 49 patients,34 (69.4%)received steroids for remission inducing,nine (18.4%)received infliximab for remission inducing and six (12.2%)achieved remission after operation.In the 44 patients treated with azathioprine (AZA)before,the median treatment time was one month and the dosage for withdrawal of AZA was (42.0 ± 14.8)mg/d.The most common reason was leucopenia (81 .8%, 36/44).Till the time point of follow-up,46 of the 49 CD patients still took MTX orally with a median treatment time of 16 months,and the weekly dosage was (12.7 ±2.0)mg.Thirty-one cases (67.4%) achieved clinical stability,while 15 cases (32.6%)underwent clinical recurrence.The median Crohn′s disease activity index (CDAI)was 123.5 ± 66.6.The weekly dosage of clinical stability group was (12.5 ±2.1)mg,and that of clinical recurrence group was (13.0 ±1 .7 )mg,there was no statistically significant difference between the two groups (t =0.802,P =0.426 ).The recurrence rate of steroids-induced remission group was 41 .2% (14/34 ),which was higher than that of infliximab and surgery-induced remission group (1/15),and the differnce was statistically significant (χ2 =5 .177,P =0.023 ). The common side effects were gastrointestinal reaction (26.5 %, 13/49 ), impaired liver function (20.4%,10/49)and leukopenia (12.2%,6/49).Only three cases could not tolerate the side effects and underwent medication withdrawal.Conclusions As a second-line immunosuppressant for maintanence remission in CD,MTX is effective and well-tolerated in patients.So it can be an important option during the long course of CD.

Objective To evaluate the therapeutic efficacy of stereotactic body radiotherapy (SBRT) with gamma knife on stage Ⅰ-Ⅱ non-small-cell lung cancer(NSCLC)and the quality of life of the patients undergoing this therapy.Methods Twenty NSCLC patients with the median age of 76,10 at stage Ⅰ and 10 at stage Ⅱ who were unable or unwilling to undergo surgery were given SBRT with gamma knife at the doses of 3-6 Gy in 8-15 fractions,finished within 2 to 3 weeks.The prescription isodose line was 50％,the marginal dose was 39-56 Gy,the central dose was 78-112 Gy,and the total biologically effective dose was 51-83 Gy.The patients were observed after admission and followed up by chest CT 1,3,6,and 12 months after treatment until progressive disease or death.EORTC QLQ-LC43 questionnaire was used to investigate the changes in quality of life.Results The 20 patients were followed up for 24 (12-46) months.At six months after the treatment,the overall response rate was 80％,and the complete response rate was 35％.The 1,2 and 3-year local control rates were 100％,95％ and 95％,respectively.The 1,2 and 3-year overall survival rates were 95％,80％ and 50％ respectively; The 1,2,and 3-year progression free survival rates were 85％,64％ and 33％,respectively.The failure rate was 20％ and the rate of progress within the planning target volume was 5％.No acute toxicity at grade 3 and over occurred in any patient during the treatment.15％ of the patients developed grade 1-2 radiation pneumonia.Age,gender,pathologic index or not were weakly correlated with the overall survival.The emotional function was improved significantly after treatment (P ＜ 0.05),dyspnea and cough were improved at different degrees,however,not significantly.There were no significant changes in the physical function and symptoms,such as fatigue,lack of appetite,insomnia,etc.Conclusions Significantly improving the motional function and maintaining the quality of life,SBRT with gamma knife is effective for elderly NSCLC patients with high local control rate fair overall survival rate and few side effects.

Objective To evaluate the clinical efficacy of infliximab (IFX) in Crohn′s disease (CD) and its effects on mucosal healing and promoting fistula closure.Methods Between September 2007 and February 2011,relevant clinical data of CD patients treated with IFX in the Department of Gastroenterology,Ruijin Hospital were collected and the efficacy and safety of IFX were retrospectively analyzed.After IFX therapy,the efficacy evaluation included laboratory index,clinical efficacy,efficacy of fistula closure and mucosal healing.The data were analyzed using t test and Wilcoxon signed-rank test.Results A total of 22 patients were enrolled in this study,11 males and 11 females; the mean age was 29.3 years.The dosage of IFX was 5 mg/kg to 10 mg/kg at week 0,2,6to induce remission,and every 8 weeks on maintenance therapy.Of 22 patients,16 patients were active CD.One case dropped out.At week 14,of the remaining 15 cases,11 cases achieved clinical remission,two cases achieved clinically effective and two cases were ineffective.Crohn′s disease activity index (CDAI) (112±80) and ESR [(13±11) mm/1 h] of week 14 decreased compared with that of week 0 [(186±88),(21± 15) mm/1 h,P=0.04 and 0.007].Two cases of 10 patients with fistula dropped out as a result of ineffective,while eight cases had a partial response and six patients sustained response during the maintenance therapy,but no fistula closed and completely disappear.Seven patients reviewed by endoscopy after five times IFX therapy (24 weeks),after therapy the simple endoscopic score for Crohn′ s disease (SES-CD) ( 3.21 ± 2.89 ) decreased compared with that before treatment (5.86±3.02) (Z＝-2.38,P＝0.018).Eleven times of adverse events were found in nine patients,infusion reaction and respiratory tract infection were more common and no severe adverse effect was observed.Conclusions IFX can rapidly improve clinical symptoms and with good safety.The effects in mucosal healing and fistula closure may occur at early medication.

ObjectiveTo investigate the clinical features and the efficacy of medium-and long-term immune suppression in the treatment of Crohn's disease (CD) in Chinese Han nationality.MethodsThe clinical data and diagnosis methods of 178 CD patients between 2003 and 2010 were analyzed.All patients received predinisone and immune suppression (azathioprine) treatment.The patients were followed up every 2 weeks.Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) were reviewed every 4 weeks.CD activity index (CDAI) was scored every 3 to 6 months.ResultsThe peak age for onset of CD was between 18 to 30 years old,and the mean time from the appearance of symptoms to diagnosis was (8.3±3.7) months.About 34.8％ (62/178 cases) patients had corresponding complications at time of diagnosis due to the progress of the disease.The average dosage of azathioprine was (1.24±0.16) mg/kg,and the total withdrawal rate due to adverse effect was 15％ (25/167 cases).The surgical intervention rate was 15.1％ (22/146 cases) during long-term follow-up.ESR and CRP of patients decreased obviously and tended to normal after 3 months treatment.The CDAI score significantly decreased after 6 months treatment.Conclusions Most Chinese patients had a good tolerance of immune suppression and achieved better medium- and long-term clinical efficacy at the dosage lower than that recommended by European and United States guidelines.

Objective To retrospectively investigate the clinical features of localized primary small bowel stromal tumors (SBSTs) and the impacting factors for prognosis.Methods The clinical and pathological data of 89 consecutive SBSTs patients,with pathologically confirmed,who underwent complete resection in Ruijin hospital between January 2003 and September 2007 were collected and analyzed.All patients were followed up for assessment of tumor recurrence and metastasis.The impacts of clinical and pathologic factors on rate of disease free survival (DFS) of the patients was evaluated.Results In total of 89 follow-up patients,15 patients were diagnosed with tumor recurrence and 9 of them died.The tumor size,mitotic index and pathological risk stratification were statistically related with DFS (P=0.000,P=0.006,P=0.000,respectively) by using Kaplan-Meier univaritate analysis.Tumor size and mitotic index were proved to be independent prognostic factors for tumor recurrence by multivariate analysis COX regression model.Conclusions Tumor size and mitotic index are related with tumor recurrence,and can be regarded as independent predictive factors of tumor recurrence.

Objective To analyze the radiolngical findings of mediastinal ganglioneuroma and to improve its diagnostic accuracy. Methods Imaging data of 8 cases of pathologically proven mediastinal ganglioueuroma were restrospectively analyzed. Results These tumors could occur in the anterior mediastinum, middle mediastinum or posterior mediastinum, with a preference for the posterior mediastinum (6/8). No specific clinical symptoms and signs were observed. Well-defined enlargrment of mediastinum with homogeneous density was shown on plain X-Ray. CT scanning was performed in 7 cases, including non-contrast scan alone (n = 3 ), both non-coutrast and contrast-enhanced scans ( n = 4). Round or oval shaped, well circumscribed, homogeneous or slightly heterogeneous, hypadense masses were demonstrated on non-contrast scan. Spotty calification could be found in a few cases. Homogeneous or slightly heterogeneous enhancement was seen following the intravenous injection of contrast material. Large tumors showed a tendency of wedging into the space between adjacent organs and structures, and encasing the nearby large vessels. MR without contrast was performed in 1 case. T1 WI showed isointensity to adjacent muscle, T2WI showed homogeneous hyperintensity. Multi-planar reconstruction provided more information concerning the relationship of the mass lesions with neighboring structures. Conclusion Mediastinal ganglioneuromas have some specific characterstics on imaging studies, which could assist in pre-operative diagnosis and surgical planning.
