Objective:To investigate the prognosis and the factors that influence it in patients with non-gastric gastrointestinal stromal tumors (GISTs) who are at low risk of recurrence.Methods:This was a retrospective cohort study. Clinicopathologic and prognostic data from patients with non-gastric GISTs and at low risk of recurrence (i.e., very low-risk or low-risk according to the 2008 version of the Modified NIH Risk Classification), who attended 18 medical centers in China between January 2000 and June 2023, were collected. We excluded patients with a history of prior malignancy, concurrent primary malignancy, multiple GISTs, and those who had received preoperative imatinib. The study cohort comprised 1,571 patients with GISTs, 370 (23.6%) of whom were at very low-risk and 1,201 (76.4%) at low-risk of recurrence. The cohort included 799 (50.9%) men and 772 (49.1%) women of median age 57 (16–93) years. Patients were followed up to July 2024. The prognosis and its influencing factors were analyzed. Receiver operating characteristic curves for tumor diameter and Ki67 were established, and the sensitivity, specificity, area under the curve (AUC) and optimal cut-off value with 95% confidence intervals were calculated. Propensity score matching was implemented using the 1:1 nearest neighbor matching method with a matching tolerance of 0.02.Results:With a median follow-up of 63 (12–267) months, the 5- and 10-year overall survival (OS) rates of the 1,571 patients were 99.5% and 98.0%, respectively, and the 5- and 10-year disease-free survival (DFS) rates were 96.3% and 94.4%, respectively. During postoperative follow-up, 3.8% (60/1,571) patients had disease recurrence or metastasis, comprising 0.8% (3/370) in the very low-risk group and 4.7% (57/1,201) in the low-risk group. In the low-risk group, recurrence or metastasis occurred in 5.5% (25/457) of patients with duodenal GISTs, 3.9% (25/645) of those with small intestinal GISTs, 9.2% (6/65) of those with rectal GISTs, and 10.0% (1/10) of those with colonic GISTs. Among the 60 patients with metastases, 56.7% (34/60) of the metastases were located in the abdominal cavity, 53.3% (32/60) in the liver, and 3.3% (2/60) in bone. During the follow-up period, 13 patients (0.8%) died of disease. Receiver operating characteristic curves were plotted for tumor diameter and Ki67 and assessed using the Jordon index. This showed that the difference in DFS between the two groups was statistically significant when the cutoff value for tumor diameter was 3.5 cm (AUC 0.731, 95% CI: 0.670–0.793, sensitivity 77.7%, specificity 64.1%). Furthermore, the difference in DFS between the two groups was statistically significant when the cutoff value for Ki67 was 5% (AUC 0.693, 95% CI: 0.624–0.762, sensitivity 60.7%, specificity 65.3%). Multifactorial analysis revealed that tumor diameter ≥3.5 cm, Ki67 ≥5%, and R1 resection were independent risk factors for DFS in patients with non-gastric GISTs at low risk of recurrence (all P<0.05). Furthermore, age >57 years, Ki67 ≥5%, and R1 resection were also independent risk factors for OS in patients with non-gastric GISTs at low risk of recurrence (all P<0.05). We also grouped the patients according to whether they had received postoperative adjuvant treatment with imatinib for 1 or 3 years. This yielded 137 patients in the less than 1-year group, 139 in the 1-year plus group; and 44 in both the less than 3 years and 3-years plus group. After propensity score matching for age, tumor diameter, Ki67, and resection status, the differences in survival between the two groups were not statistically significant (all P>0.05). The 10-year DFS and OS were 87.5% and 95.5%, respectively, in the group treated with imatinib for less than 1 year and 88.5% and 97.8%, respectively, in the group treated for more than 1 year. The 10-year DFS and OS were 89.6% and 92.6%, respectively, in the group treated with imatinib for less than 3 years and 88.0% and 100.0%, respectively, in the group treated with imatinib for more than 3 years. Conclusion:The overall prognosis of primary, non-gastric, low recurrence risk GISTs is relatively favorable; however, recurrences and metastases do occur. Age, tumor diameter, Ki67, and R1 resection may affect the prognosis. For some patients with low risk GISTs, administration of adjuvant therapy with imatinib for an appropriate duration may help prevent recurrence and improve survival.

Objective: To understand the relationship between serum 25 hydroxyvitamin D [25(OH)D] levels and social emotional functions in children with autism spectrum disorder (ASD), in order to provide the reference for comprehensive interventions in ASD children. Methods: From January to June 2024, 124 ASD children aged 1-3 who received rehabilitation training at designated rehabilitation institutions in Nantong City, China were selected as the case group, while 124 healthy gender and age matched children who underwent health examinations at the same time were selected as the control group. The study used liquid chromatography-mass spectrometry to measure serum 25(OH)D levels in both groups of children. The Chinese Infant-Toddler Social and Emotional Assessment (CITSEA) was used to evaluate the emotional and socialization functioning of children with ASD, and to explore the relationship between serum 25(OH)D levels and their emotional and social functioning. Results: The serum 25(OH)D levels were lower in the case group [(59.22±19.96)nmol/L] compared to the control group [(85.50±21.59)nmol/L], and the rate of 25(OH)D deficiency or insufficiency (21.77%) was higher than that of the control group (7.26%), with statistically significant differences ( t/χ 2=-7.75, 8.91, P <0.01). The CITSEA evaluation results showed that the scores of the explicit behavior domain, implicit behavior domain, dysregulation domain, and ability domain in children with ASD were (63.37±10.44, 56.29± 9.36 , 57.04±10.65, 38.92±17.91) points, and the abnormal detection rates were 50.81%, 35.48%, 41.13%, and 45.16%, respectively. Among them, the abnormal detection rates of the explicit behavior domain and ability domain were higher in boys ( 57.14 %, 51.02%) compared to girls (34.62%, 23.08%), and the differences were statistically significant ( χ 2=4.18, 6.48, P < 0.05 ). The abnormal detection rates of explicit behavioral domains and dysregulated domains in ASD children with insufficient or deficient serum 25(OH)D (77.78%, 59.26%) were higher than those in the normal serum 25(OH)D group (37.11%, 18.56%), and the differences were statistically significant ( χ 2=14.06, 17.58, P <0.01). Conclusion The serum 25(OH)D levels in children with ASD are significantly lower compared to levels in healthy children, and developmental abnormalities in social emotional functioning are common concurrent problems.

Intestinal flora can mediate intestinal inflammation to the joint site through the"gut-joint axis",activate local or systemic immune response,and cause joint inflammation and injury.Traditional Chinese medicine(TCM)has unique advantages in the treatment of autoimmune diseases.Recent studies have shown that the interaction between TCM and intestinal flora in the mucosal immune system is closely related to the occurrence and development of autoimmune diseases.Therefore,the possible therapeutic mechanism of the interaction of TCM and intestinal flora in autoimmune arthritis is discussed in this paper,with the view of"gut-joint axis",in order to bring new ideas for clinical prevention and treatment.

Objective:To explore the application value of the method of judging the density of small shadows in the lung area by using CT and CT reference films for pneumoconiosis.Methods:The chest imaging data of 244 employees of a large copper company in Tongling City, Anhui Province who underwent occupational physical examination at Tongling Municipal Hospital in Anhui Province from January 2016 to December 2019 were retrospectively analyzed. Totally 244 cases underwent chest CT scan and chest DR radiography at the same time. The shape and size of the small shadows (the size of the circular and quasi-circular nodules in the lung area were represented by p, q, r, and the size of the irregular small shadows were represented by s, t, u), the overall density, the density of small shadows in each lung area, the large shadows, and the diagnosis stage were observed and compared. The small shadow density of each lung area was judged by the method of judging the small shadow density of CT lung area and the reference film, and other observation indicators were judged according to GBZ70-2015 Diagnosis of Occupational Pneumoconiosis. Results:There was a significant difference between CT and DR in judging s-shaped small shadows and no small shadows ( P<0.05), and there was no statistically significant difference in judging p, q, r, t, and u-shaped small shadows ( P>0.05). CT and DR had medium to high consistency in the judgment of the overall density of small shadows (Kappa=0.692, P=0.001), and the diagnostic coincidence rate was 82.38% (201/244). There was moderate to high agreement between CT and DR in the density of small shadows shown in the right upper, right lower, left upper, left middle, and left lower lung regions (Kappa ranged from 0.40 to 0.75, P<0.05), and the consistency in the right middle lung region was poor (Kappa=0.381, P=0.001). Eleven large shadows were detected in 8 cases by DR, 31 large shadows were detected in 23 cases by CT, and 20 (8.20%) large shadows were detected more frequently by CT than DR. The agreement between CT and DR for the diagnosis and staging of silicosis was excellent (Kappa=0.843, P=0.001), and the diagnostic coincidence rate was 91.80% (224/244). Conclusion:Applying the method of determining the density of small shadows in the lung area of pneumoconiosis and reference films, combined with GBZ70-2015 Diagnosis of Occupational Pneumoconiosis, can make a more accurate diagnosis of silicosis.

Objective:To investigate the status of work performance among rural doctors in Shanxi province and the factors related to their performance.Methods:From July to September 2019, 528 rural doctors in Shanxi province were selected by multi-stage stratified cluster sampling for the survey. Their job competency, job performance, psychological capital and burnout were evaluated. The structural equation model was used to construct the job performance analysis based on post competency.Results:The total score of post competency of rural doctors in Shanxi province was (188.6±20.3), and the total score of job performance was (71.3±11.5), both of which were in the middle level. The structural equation model was well fitted [goodness-of-fit index (GFI)=0.958, normal fix index (NFI)=0.920, adjusted goodness-of-fit index (AGFI)=0.910, root mean square error of approximation (RMSEA)=0.076]. Post competency, psychological capital and job burnout had direct effects on job performance ( P<0.05), with influence coefficients of 0.64, 0.35 and -0.25, respectively. Job competency indirectly affected job performance through psychological capital and job burnout ( P<0.05). Conclusion:The study suggest that higher post competency would facilitate to improve the work performance of rural doctors.

OBJECTIVE：To e xplore the health economic burden of hypertension patients at county-level areas and its influential factors in China. METHODS ：A questionnaire survey was conducted on hypertension patients in 7 county-level public hospitals from 6 provinces as Hebei ，Shandong，Shanxi provinces by using a convenient sampling method. Catastrophic health expenditure was defined by the standard of “medical and health expenditure exceeding 10％ of household income ”. The incidence ， average gap and relative gap of catastrophic health expenditure were analyzed. A multi-factor Logistic regression model analysis was used to analyze the influential factors that lead to catastrophi c health expenditure. RESULTS ：A total of 1 378 questionnaires were sent out ，and 925 valid questionnaires were collected with effective rate of 67.13％ . The incidence of catastrophic health expenditure，average gap and relative gap among hypertension patients were 23.03％，19.37％ and 84.12％，respectively. At different income levels ，the incidence of catastrophic health expenditure，average gap and relative gap were 72.67％ ， 96.79％ and 133.18％ in the poorest household group ，and were 1.94％ ，0.47％ and 24.23％ in the richest household group. Among different types of medical insurance ，the incidence of catastrophic health expenditure in patients covered by “New Rural Cooperative Medical Scheme （NRCMS）”the highest （31.30％）. The household income ，complications and the type of health insurance had significant impacts on the incidence of catastrophic health expenditure in hypertension patients （P＜0.05）. CONCLUSIONS：The incidence of catastrophic health expenditure in hypertension patients with different income levels is different. As the income level raised ，the incidence of catastrophic health expenditures continued to decrease. But the protection of household health expenditure by NRCMS is weak. It is suggested that a certain policy preference should be given to families with low income and patients with chronic diseases ，so as to ensure the rights and interests of patients with hypertension .

OBJECTIVE： To establish content determination method of Triptolide-glycyrrhetic acid compound microemulsion， optimize the formula and investigate its physicochemical properties and release rate in vitro. METHODS： The content of Triptolide- glycyrrhetic acid compound microemulsion was determined by UPLC. The determination was performed on ACQUITY UPLC BEH C18 column with mobile phase consisted of 0.1％ formic acid aqueous solution-acetonitrile （gradient elution） at the flow rate of 0.4 mL/min. The column temperature was 40 ℃. The detection wavelength was set at 218 nm， and sample size was 5 μL. Pseudo-ternary phase diagrams were drawn by water titration method. Using oil phase， surfactants and co-surfactants as index， the formula was optimized， and in intro release characteristics was investigated by in vitro release test. RESULTS： The linear range of triptolide and glycyrrhetinic acid were 1-40 μg/mL（r＝0.999 7） and 10-400 μg/mL（r＝0.999 8）， respectively. The limits of quantitation were 0.5 and 0.8 μg/mL； the limits of detection were 0.1 and 0.2 μg/mL. RSDs of precision， stability and reproducibility tests were all less than 2％. Average recoveries were 100.32％-101.15％ （RSD＝0.36％， n＝6）， 99.78％-101.42％ （RSD＝0.59％，n＝6）. The optimal formula included that medium chain triglyceride as oil phase， polyethylene glycol hydroxy stearate as surfactants， ethanol as co-surfactants， water as water phase， the proportion of them was 8 ∶  28 ∶ 14 ∶ 50. The obtained microemulsion was O/W type， being transparent and clear， with average diameter， average polydispersity index and average viscosity of （62.38±3.44） nm， 0.096±0.001 and （26.84±1.10） mPa·S. Within 24 h， cumulative release rates of triptolide and glycyrrhetinic acid in obtained microemulsion were 99.8％ and 99.7％ （in PBS pH 2.0）， 99.3％ and 99.4％ （in PBS pH 7.4）， 98.9％ and 98.4％ （in PBS pH 9.0）， respectively. Triptolide and glycyrrhetinic acid released faster in the single microemulsion than in the compound microemulsion. CONCLUSIONS： Established content determination method is simple and stable. The optimized formula is stable and feasible. Obtained iriptolide-glycyrrhetinic acid compound microemulsion show better sustained-release effect than sigle microemulsion.

OBJECTIVE： To evaluate the economics of the full coverage policy for hypoglycemic essential medicines in Taizhou city， and to provide reference for improving medicine accessibility and essential medicine system in China. METHODS： The electronic health records and financial input data of diabetic patients were extracted from different districts and counties of Taizhou city during 2009-2016. In cohort study design， taking the implementation time of each district and county’s policies as the breakpoint， the data recorded annually were processed as annual data， forming the cohort data for 1 year before （baseline year） and 3 years after the implementation of the policies. According to the choice of free medicines after the implementation of the policy， they were divided into policy group and control group. Propensity score matching was used to balance the differences between two groups to get the final sample， and then the economics of the policy was evaluated with the methods of difference-in-differences. The cost and benefit of implementation policy were calculated. RESULTS： Totally 14 744 people of each group were got by propensity score matching. The mean annual financial expenses on free medicine per capita were 263.8 yuan. Compared with baseline year， mean annual medicine expenses per capita reduced by the policy were 649.2 yuan， and mean annual hospitalization expenses per capita were 624.7 yuan. Thus the input-output ratio of the policy was 1 ∶ 4.8. CONCLUSIONS： The implementation of the policy is beneficial to reduce the cost burden of patients and economical. It can be popularized and sustained through scientific design combined with relevant policies.

Objective: The aim of this study was to analyze the health-related quality of life (HRQoL) and their influencing factors in patients with asymptomatic unruptured intracranial aneurysms (UIAs) after endovascular treatment. Methods: We retrospectively reviewed 44 patients with asymptomatic UIAs (56aneurysms) received endovascular treatment in Xuanwu Hospital of Capital Medical University from January 2015 to May 2017. The average follow-up time was (28 ±9) month. The clinical data of patients were collected, and the HRQoL was evaluated by the SF-36 questionnaire. The SF-36 results and influencing factors were analyzed. Results: Forty-four patients with UIAs in this study showed significantly lower body pain,physical function,and mental health in the three dimensions of the SF-36 scale than the normal population in China (75 ± 15,82 ± 15 and 71 ± 14 vs. 83 ±20,88 ± 17 and 79 ± 15;t =2.89,2. 14 and 3. 34 Respectively; all P < 0. 05). The results of univariate analysis showed (hat the Mental Component Summary score (MCS) of patients with sleep duration < 6 h and ≥6h were respective 63 ± 18 and 79 ± 14points (t = -2.41);the MCS score of patients with disease duration ≤3 months and > 3 months were respective 76 ±15 and 89 ± 7 points (t = -2. 11); the differences were significant (both P < 0. 05). The physical component summary score (PCS) of sleep duration < 6 h and ≥ 6 h were respective 63 ± 22 and 77 ± 17 (t = - 2. 11); the PCS of ≤3 months and > 3 months were respective 73 ± 17 and 90 ± 5 (l = -2.74);the differences were significant (both P <0.05). Multivariate analysis showed that the course of disease ≤ 3 months was the independent risk factor of PCS (95% CI 2. 23 -27. 42, P = 0. 02), and sleep time<6h was the independent risk factor of MCS (95% CI 1. 44 -28. 92, P = 0. 03). 12.5% (4/32) of these patients failed to recover to normal work before treatment even after long-term recovery (28 ± 9 months). Conclusions: HRQoL results in patients with asymptomatic UIAs after endovascular treatment were lower than those in the general population in multiple dimensions of SF-36. The course of disease ≤3 months and daily sleep time < 6h are independent risk factors for PCS and MCS,respectively.
