Objective:To explore the influencing factors for compliance to colonoscopy screening for colorectal cancer in outpatients.Methods:Patients aged 40-74 years who visited the outpatient gastroenterology department of 7 tertiary hospitals in 7 regions of Xinjiang from January 2022 to June 2022 were enrolled. Recommendations for colonoscopy screening were made according to the patient's medical conditions, and the questionnaire was used to collect information. The Chi-square test was used to compare the differences of compliant and non-compliant patients. Multivariate logistic regression was used to analyze the influencing factors of compliance to colonoscopy screening.Results:A total of 463 valid questionnaires were obtained from 7 centers, in which, 427 outpatients (92.2%) followed the recommendation for colonoscopy screening, and 36 (7.8%) did not. Chi-square test results showed that there were statistically significant differences between the two groups in gender, age, education, subjective cognition of intestinal polyps, personal history of colorectal polyps, family history of colorectal cancer, family history of colorectal polyps, abdominal pain or distension, and defecation habit or stool changes ( P<0.05). The results of multivariate regression analysis showed that the screening compliance of patients aged 40-49 years ( P=0.005, OR=0.141, 95% CI: 0.036-0.549) and 50-59 years ( P=0.039, OR=0.257, 95% CI: 0.071-0.932) was lower than that of patients aged 60-74 years. The screening compliance of patients with high school education ( P=0.011, OR=3.121, 95% CI: 1.304-7.473) and college education or above ( P=0.016, OR=3.544, 95% CI: 1.270-9.890) was higher than those with primary school education and below. Patients with personal history of colorectal polyps ( P=0.015, OR=12.288, 95% CI: 1.629-92.719), family history of colorectal cancer ( P=0.038, OR=8.506, 95% CI: 1.124-64.351) and changes in defecation habit or stool trait ( P=0.039, OR=4.794, 95% CI: 1.085-21.192) also had higher compliance. Conclusion:Age, educational level, personal history of colorectal polyps, and family history of colorectal cancer are related to colonoscopy screening compliance in outpatients of 7 tertiary hospitals in 7 regions of Xinjiang. The independent risk factors affecting compliance to colorectal cancer screening in outpatients are age of 40-59 years, lower educational level, no previous history of polyps or family history of colorectal cancer, and no defecation habit or stool changes.

Objective To observe the value of 18F-fluoro-dihydroxy-phenylalanine(18F-FDOPA)PET/CT for evaluating the efficacy of radiochemotherapy for advanced glioma.Methods Data of 84 patients with advanced glioma who received precision radiotherapy combined with synchronous chemotherapy were retrospectively analyzed.The patients were divided into effective group(complete remission+partial remission+stable disease,n=60)and ineffective group(progressive disease,n=24)according to the efficacy of radiochemotherapy.18F-FDOPA PET/CT metabolic parameters of tumors,including tumor metabolic tumor volume(MTV),maximum standard uptake value(SUVmax)and mean standard uptake value(SUVmean)were compared between groups,also before and after radiochemotherapy within groups.Spearman correlation analysis was used to observe the correlations of metabolic parameters and the efficacy of radiochemotherapy.Results After radiochemotherapy,MTV,SUVmax and SUVmean of tumors in effective group were lower than those of tumors in ineffective group(all P＜0.05).Significant differences of metabolic parameters were found before and after radiochemotherapy in effective group(all P＜0.05).MTV,SUVmax and SUVmean of advanced glioma were negatively correlated with the efficacy of radiochemotherapy(r=-0.63,-0.52,-0.50,P＜0.001,P=0.007,P=0.010).Conclusion 18F-FDOPA PET/CT was helpful for evaluating the efficacy of radiochemotherapy for advanced glioma.

Background::Psychological stress has been reported to be a potential risk factor for hypertension among females, but it remains unclear whether spousal chronic stress levels alter the risk of hypertension among women. We examined the associations between stress within the family and hypertension among married women.Methods::Reproductive-aged women who were planning for pregnancy and their husbands were recruited from the National Free Pre-pregnancy Checkup Projects (NFPCP) across 31 provinces in China in 2016 and 2017. Perceived stress of wives or husbands was measured with a 5-point Likert-type scale, and assessed from three domains: work/life-related stress, economic stress, and overall stress. Multivariable-adjusted logistic regression models were used to assess the associations between stress status and the prevalence of hypertension.Results::Of 10,027,644 couples, 261,098 (2.60%) women had hypertension. The results showed that higher stress levels among themselves or their husbands were associated with a higher prevalence of hypertension in women ( Pfor trend <0.001). Compared with non-stressed participants, female participants with the highest stress themselves were at a greater risk of hypertension, with adjusted odds ratio (OR) of 1.31 (95% confidence interval [CI]: 1.25-1.37); and compared with participants whose husbands had no stress, those whose husbands had the highest stress level were at a higher risk of hypertension with adjusted OR of 1.24 (95% CI: 1.20-1.29). Moreover, compared with non-stressed status for both couples, only-wife-stressed, only-husband-stressed, and both-stressed couples were found to be significantly associated with increased risks of wives’ hypertension, with adjusted ORs of 1.28 (95% CI: 1.25-1.31), 1.19 (95% CI: 1.17-1.21), and 1.28 (95% CI: 1.26-1.31), respectively. Conclusion::Moderate to severe stress in both spouses might be associated with female hypertension prevalence, which highlights the importance of paying attention to the psychological stresses of couples within the family.

Objective:To investigated the prevalence of anxiety and depression symptoms in patients with colorectal polyps in part of Xinjiang area and to explore the associated influencing factors related to psychological status, and to provide evidence and clues to promote the diagnosis and treatment of psychosomatic diseases in digestive system.Methods:From December 2021 to June 2022, at the First Affiliated Hospital of Shihezi University, the Fourth Division Hospital of Xinjiang Production and Construction Corps, the Third Division Hospital of Xinjiang Production and Construction Corps (Kashgar Hospital), the Thirteenth Division Red Star Hospital of Xinjiang Production and Construction Corps, the Tenth Division Beitun Hospital of Xinjiang Production and Construction Corps, the Seventh Division Hospital of Xinjiang Production and Construction Corps, the Fifth Division Hospital of Xinjiang Production and Construction Corps, patients who underwent colonoscopy and colorectal polyps detected were enrolled. The generalized anxiety disorder scale-7 (GAD-7) was used to screen anxiety symptoms, and the patient health questionaire-8 (PHQ-8) was performed to screen depression symptoms, and the general situation questionnaire was used to collect clinical information of patients. The questionnairs were completed via the Questionnaire Star platform or paper questionnaire, and a database was established. The patients were divided into groups according to whether with anxiety and depression symptoms. Multivariable logistic regression models was performed to analyze the factors related to anxiety and depression.Results:A total of 516 questionnaires were distributed and collected, among which 9 questionnaires were incomplete and 507 questionnaires were valid, the effective rate of questionnaires was 98.26%. The detection rates of anxiety and depression symptoms in 507 patients with colorectal polyps were 21.50%(109/507) and 19.33%(98/507), respectively. The results of multivariable logistic analysis revealed that female ( OR=3.87, 95% confidence interval (95% CI) 2.30 to 6.51, P<0.001), maximum diameter of polyp ( OR=1.74, 95% CI 1.14 to 2.67, P=0.011), perception of polyps as cancer ( OR=13.96, 95% CI 1.48 to 132.07, P=0.022), and the occurrence of gastrointestinal symptoms after polyp detection ( OR=5.43, 95% CI 1.74 to 16.92, P=0.004) were independent risk factors of anxiety in patients with colorectal polyps. Female ( OR=2.42, 95% CI 1.47 to 4.00, P=0.001), the number of polyps ( OR=1.07, 95% CI 1.01 to 1.13, P=0.028) and the count of gastrointestinal symptoms ( OR=2.04, 95% CI 1.34 to 3.10, P=0.001) were independent risk factors of depression in patients with colorectal polyps. Conclusion:Gender, polyp size, number of polyps, disease perception, and concomitant gastrointestinal symptoms are associated with anxiety and depression in patients with colorectal polyps.

According to the differences in function and structure, the nasal cavity can be roughly divided into three regions:the vestibule, respiratory zone, and olfactory zone. The current mainstream of research believes that the process of drugs entering the brain through the nasal cavity mainly occurs in the latter two regions, with the olfactory zone being the primary area. To allow more effective ingredients to enter the brain or reach the above-mentioned delivery pathway targets quickly, when developing related drug products, it should be possible to deliver the drug to the upper nasal cavity, like the upper respiratory zone and olfactory zone. Therefore, special drug delivery devices that can target the upper nasal cavity play a key and core role in Nose-to-Brain delivery. It is nasal spray device Nose-to-Brain delivery products approved by FDA mainly use. The following are three main research directions of the Nose-to-Brain delivery devices. 1) In-depth assessment and research of critical quality attributes and their influencing factors. Many research institutions and enterprises have conducted extensive research on liquid or powder sprays aided by nasal spray devices, and it is currently agreed that spray pattern, plume geometry, and particle size are the critical quality attributes, which can be mainly affected by spray devices and content properties. A spray with a smaller angle can penetrate the nasal valve easier and deliver to the upper nasal cavity. 2) The study of delivery platforms for such complex drug-device combinations is also a key direction, such as Exhalation Delivery Systems (EDS), Precision Olfactory Delivery Systems (POD®), and Controlled Particle Dispersion Technology (CPD) platforms, etc., which are general technology platforms established by drug delivery device manufacturers to better achieve Nose-to-Brain delivery. They have indeed achieved more accurate drug delivery, more significant therapeutic effects, and more convenient use for patients. 3) Combining drug delivery devices with new technologies. For example, adding mucosal adsorbents and permeation enhancers to the prescription, and preparing medicinal products using nanoparticle formulation technology. It is new directions for future research and development which can further meet the needs of Nose-to-Brain delivery. Nose-to-Brain delivery bring new hope to a wide range of clinical needs for brain diseases due to its special advantages. In order to play the truly important role of Nose-to-Brain delivery, it is not only the industry make efforts in research and industrialization, but also regulatory aspects need scientific evaluation and reasonable regulation of emerging technologies. Here are our thoughts. First, we need to pay attention to the important role of regulatory science in the technical research and evaluation of Nose-to-Brain delivery products. Next, we need to pay attention to the interaction and collaboration between scientific researchers, industry, regulators, and users. Then, regulatory authorities needs to broaden its thinking flexibility and attach importance to the role of individual drug guidelines, summary key technical points and solutions from multiple cases. Finally, we need to pay attention to the design, research and development support, and industrialization security of domestic drug delivery devices.

Objective: Gut—microbiota—brain axis plays a role in the pathogenesis of Parkinson’s disease (PD). The subdiaphragmatic vagus nerve serves as a major modulatory pathway between the gut microbiota and the brain. However, the role of subdiaphragmatic vagus nerve in PD pathogenesis are unknown. Here, we investigated the effects of subdiaphragmatic vagotomy (SDV) on the neurotoxicity in the mouse striatum and colon after administration of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP). Methods: Sham or SVD was performed. Subsequently, saline or MPTP (10 mg/kg × 3, 2-hour interval) was administered to mice. Western blot analysis of tyrosine hydroxylase (TH) and dopamine transporter (DAT) in the striatum and phosphorylated α-synuclein (p-α-Syn) in the colon was performed. Results: Repeated administration of MPTP significantly caused reduction of TH and DAT in the striatum and increase of p-α-Syn in the colon of mice. However, SDV did not affect the reduction of TH and DAT in the striatum and increases in p-α-Syn in the colon after repeated MPTP administration. Conclusion These data suggest that subdiaphragmatic vagus nerve doses not play a role in the MPTP-induced neurotoxicity in the brain and colon.

Objectives:To investigate the risk factors and short-term prognosis of early pulmonary hypertension (PH) in preterm infants.Methods:A retrospective case-control study was performed in preterm infants (gestational age <32 weeks) in the neonatal intensive care unit (NICU) of the Children′s Hospital, Zhejiang University School of Medicine from January 2012 to December 2019. Eighty preterm infants with a diagnosis of PH between 3 and 14 days (early PH group) were matched in gestational age and sex with the controls (1∶2) of the same period in NICU. Perinatal clinical records, complications, echocardiography and early outcomes were collected. Characteristics and outcomes were compared between the two groups with t-test, nonparametric test or Chi-square test. Multivariate Logistic regression was used to analyze the predictive factors of early PH. Results:The gestational age of the early PH group and the control group were both (27.9±1.4) weeks, and 52 (65.0%) and 104 (65.0%) were males in each group, respectively. Univariate analysis showed that birth weights were lower in the early PH group than those in the control group (1 030 (850, 1 200) vs. 1 110 (1 000, 1 278) g, Z=-3.27, P=0.001). The early PH group had higher rates of pregnancy-induced hypertension, prolonged rupture of membranes (PROM) >1 week, born by caesarean, small for gestational age (SGA), 1 and 5 min Apgar score ≤7 scores, neonatal respiratory distress syndrome (RDS) and hemodynamic significant patent ductus arteriosus (hsPDA) (12.5% (10/80) vs. 3.8% (6/160), 11.2% (9/80) vs. 3.8% (6/160), 48.8% (39/80) vs. 28.8% (46/160), 10.0% (8/80) vs. 1.9% (3/160), 70.8% (51/72) vs. 51.7% (74/143), 50.0% (36/72) vs. 20.3% (29/143), 88.8% (71/80) vs. 59.4% (95/160), 85.0% (68/80) vs. 22.5% (36/160), χ 2=6.56, 5.12, 3.31, 8.05, 7.17, 20.05, 21.58, 84.84, all P<0.05). Multivariate Logistic regression analysis showed that the independent predictive factors of early PH were PROM >1 week, SGA, 5 min Apgar score ≤7 scores, nenonatal RDS and hsPDA ( OR=10.40, 18.61, 4.47, 4.13, 20.10, 95% CI 1.93-56.12, 2.82-122.76, 1.91-10.46, 1.50-11.39, 8.28-48.80, all P<0.05),respectively. Infants with early PH had higher incidence of bronchopulmonary dysplasia (BPD), BPD associated PH, severe intraventricular hemorrhage (IVH), extrauterine growth retardation (EUGR), laser treatment for retinopathy of prematurity (ROP) and mortality than the controls (all P<0.05). The duration of invasive mechanical ventilation was also longer in the early PH group than that in the control group ( P<0.05). Conclusions:Risk of early PH will be increased in preterm infants with PROM >1 week, SGA, 5 min Apgar score ≤7 scores, and comorbidities of nenonatal RDS and hsPDA. Early PH is associated with increased mortality, BPD, BPD associated PH, severe IVH, EUGR and laser treatment for ROP.

Objective: Exposure to the herbicide glyphosate during pregnancy and lactation may increase the risk for autism spectrum disorder (ASD) in offspring. Recently, we reported that maternal exposure of formulated glyphosate caused ASD-like behaviors in juvenile offspring. Here, we investigated whether maternal exposure of pure glyphosate could cause ASD-like behaviors in juvenile offspring. Methods: Water or 0.098% glyphosate was administered as drinking water from E5 to P21 (weaning). Behavioral tests such as grooming test and three-chamber social interaction test in male offspring were performed from P28 to P35. Results: Male offspring showed ASD-like behavioral abnormalities (i.e., increasing grooming behavior and social interaction deficit) after maternal exposure of glyphosate. Conclusion The findings suggest that the exposure of glyphosate during pregnancy and lactation may cause ASD-like behavioral abnormalities in male juvenile offspring. It is likely that glyphosate itself, but not the other ingredients, may contribute to ASD-like behavioral abnormalities in juvenile offspring.
