OBJECTIVE: The present study evaluated the effects of deep acupuncture at Weizhong acupoint (BL40) on bladder function and brain activity in a rat model of overactive bladder (OAB), and investigated the possible mechanisms around the acupuncture area that initiate the effects of acupuncture. METHODS: Adult female Sprague-Dawley rats were randomly divided into six groups, comprising a control group, model group, group treated with deep acupuncture at BL40, group treated with shallow acupuncture at BL40, group treated with acupuncture at non-acupoint next to BL40, and group treated with acupuncture at Xuanzhong (GB39). Urodynamic evaluation was used to observe the urination, and functional magnetic resonance imaging was used to observe the brain activation. The mechanism of acupuncture at BL40 in regulating bladder function was explored by toluidine blue staining and enzyme-linked immunosorbent assay, and the mechanism was verified by stabilizing mast cells (MCs) or blocking tibial nerve. RESULTS: Deep acupuncture at BL40 significantly increased the intercontraction interval in OAB rats and enhanced the mean amplitude of low frequency fluctuation of primary motor cortex (M1), periaquaductal gray matter (PAG), and pontine micturition center (PMC). It also increased the zero-lag functional connectivity between M1 and PAG and between PAG and PMC. Shallow acupuncture at BL40 and acupuncture at non-acupoint or GB39 had no effect on these indexes. Further studies suggested that deep acupuncture at BL40 increased the number and degranulation rate of MCs as well as the contents of 5-hydroxytryptamine, substance P, and histamine in the tissues around BL40. Blocking the tibial nerve by lidocaine injection or inhibiting MC degranulation by sodium cromoglycate injection obstructed the effects of acupuncture on restoring urinary function and modulating brain activation in OAB rats. CONCLUSION Deep acupuncture at BL40 may be more effective for inhibiting OAB by promoting degranulation of MCs around the acupoint and stimulating tibial nerve, thereby regulating the activation of the brain area that controls the lower urinary tract.

[Purpose]To analyze the compliance and influencing factors of endoscopic screening in high-risk population of upper gastrointestinal cancer(UGC)in Chongqing Municipality.[Methods]Risk assessment of UGC was conducted among residents aged 40～74 years old in the areas covered by the Chongqing Urban Cancer Early Diagnosis and Treatment Program from 2012 to 2019.The residents with high risk of UGC were advised to receive free endoscopic screening in designated hospitals.The compliance and influencing factors of endoscopic screening among high-risk sub-jects were analyzed.[Results]There were 266 611 residents who completed the questionnaires and UGC risk assessment,among whom 48 000(18.00％)were assessed as high risk.A total of 9 162 high-risk individuals received the following endoscopic screening with a compliance rate of 19.09％.Multivariate Logistic regression analysis showed that residents aged 45～64 years old,with high school or above education,divorced or widowed status,occupational exposure to haza-rdous substances,hot food preference,high fat diet,frequent consumption of pickled and dried food,exposure to kitchen fume,psychic trauma or depression,upper gastrointestinal disease his-tory and family history of UGC were likely to accept endoscopic screening;while those aged 70 years old and above,current smokers,and having regular physical exercise were likely to have low compliance.[Conclusion]Among high-risk residents of UGC in Chongqing,the compliance to endoscopic screening needs be improved,health education and management should be targeted to those likely to have low compliance.

Objective: To analyze and compare therapy responses, outcomes, and incidence of severe hematologic adverse events of flumatinib and imatinib in patients newly diagnosed with chronic phase chronic myeloid leukemia (CML) . Methods: Data of patients with chronic phase CML diagnosed between January 2006 and November 2022 from 76 centers, aged ≥18 years, and received initial flumatinib or imatinib therapy within 6 months after diagnosis in China were retrospectively interrogated. Propensity score matching (PSM) analysis was performed to reduce the bias of the initial TKI selection, and the therapy responses and outcomes of patients receiving initial flumatinib or imatinib therapy were compared. Results: A total of 4 833 adult patients with CML receiving initial imatinib (n=4 380) or flumatinib (n=453) therapy were included in the study. In the imatinib cohort, the median follow-up time was 54 [interquartile range (IQR), 31-85] months, and the 7-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.2%, 88.4%, 78.3%, and 63.0%, respectively. The 7-year FFS, PFS, and OS rates were 71.8%, 93.0%, and 96.9%, respectively. With the median follow-up of 18 (IQR, 13-25) months in the flumatinib cohort, the 2-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.4%, 86.5%, 58.4%, and 46.6%, respectively. The 2-year FFS, PFS, and OS rates were 80.1%, 95.0%, and 99.5%, respectively. The PSM analysis indicated that patients receiving initial flumatinib therapy had significantly higher cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) and higher probabilities of FFS than those receiving the initial imatinib therapy (all P<0.001), whereas the PFS (P=0.230) and OS (P=0.268) were comparable between the two cohorts. The incidence of severe hematologic adverse events (grade≥Ⅲ) was comparable in the two cohorts. Conclusion: Patients receiving initial flumatinib therapy had higher cumulative incidences of therapy responses and higher probability of FFS than those receiving initial imatinib therapy, whereas the incidence of severe hematologic adverse events was comparable between the two cohorts.

Objective: To understand the associations between internet addiction, screen time (computer/mobile devices use and television watching time) and depressive symptoms in adults. Methods: A total of 6 932 adults aged <60 years from the Tianjin Chronic Low-grade Sgstemic Inflammation and Health (TCLSIH) Cohort of 2013-2019 were surveyed. The information about their computer/mobile devices use and television watching time were collected by using a self-reported questionnaire. The depressive symptoms were assessed using the self-rating depression scale (SDS). The adults surveyed were divided into two groups: non-depressive symptom group (SDS score <45) and depressive symptom group (SDS score ≥45). The associations between internet addiction, screen time and depressive symptoms were estimated using Cox proportional hazard regression models, with adjusting for multiple confounders. Results: After adjusting for confounding factors, the hazard ratios (HRs) of depressive symptom in the adults who had internet addiction before, had light internet addiction and had moderate or severe internet addiction were 0.83 (95%CI: 0.56-1.23) , 1.20 (95%CI: 1.03-1.41) for light and 1.48 (95%CI: 1.16-1.89), respectively, compared with those without internet addiction. The linear trend test results of the association between internet addiction and depressive symptoms was significant (trend P<0.001). Compared with the adults who used computer/mobile devices for <1 hour/day, the HRs of depressive symptoms in those who used computer/mobile devices for >1 hour, >3 hours, >5 hours and >10 hours were 0.59 (95%CI: 0.40-0.88), 0.58 (95%CI: 0.40-0.85), 0.52 (95%CI: 0.36-0.76) and 0.69 (95%CI: 0.45-1.05) respectively, a U-shaped association was found between computer/mobile devices use time and depressive symptoms (trend P<0.001). Compared with the adults who never watch TV, the HR of depressive symptoms was 1.36 (95%CI:1.09-1.69) for those watching TV for ≥3 hours/day in crude model and 1.34 (95%CI: 1.07-1.68) for those watching TV for ≥3 hours/day in adjusted model (trend P<0.001). Conclusion: Our findings suggested that internet addiction and television watching time were associated with an increased risk of depressive symptoms, while computer/mobile device use time was associated with a reduced risk of depressive symptoms.

Objective: To examine the associations of childhood obesity, assessed by genetic variations of childhood body mass index (BMI), with the risk of adult ischemic heart disease (IHD) and major coronary event (MCE). Methods: More than 69 000 participants from the China Kadoorie Biobank were genotyped. After excluding those with coronary heart disease, stroke, or cancer at baseline, a total of 64 454 participants were included in this study. Based on genome-wide significant single nucleotide polymorphisms (SNPs), childhood BMI genetic risk score were constructed for every participant and divided into quintiles, with the lowest quintile as the low genetic risk group and the highest quintile as the high genetic risk group. Cox proportional hazards regression models were used to estimate the association between genetic predisposition to childhood obesity and the risk of ischemic heart disease. Results: During a median of 10.7 years of follow-up, 7 073 incident cases of IHD and 1 845 cases of MCE were documented. After adjusting for sex, age, region, and the first ten genetic principal components, the HRs (95%CIs) for IHD and MCE in the high genetic risk group were 1.10 (1.02-1.18) and 1.10 (0.95-1.27), compared with the low genetic risk group. IHD risk increased by 4% (2%-6%) for each one standard deviation increase in genetic risk score (trend P=0.001). After further adjustment for baseline BMI, the differences between genetic risk groups were not statistically significant, but there was still a linear trend between genetic risk score and IHD risk (trend P=0.019). Conclusions: IHD risk increased with genetic predisposition to childhood obesity, suggesting that childhood obesity is an important risk factor for the development of IHD in China. As an easily identifiable feature, changes of childhood BMI should be monitored regularly to realize early intervention of IHD in adults.

OBJECTIVE: To investigate whether β-globin gene 3'UTR+101G>C (HBB:c.*233G>C) variant has genetic effect and provide basis for gene diagnosis and genetic counseling. METHOD: Whole blood cell analysis and capillary zone electrophoresis (CZE) were used to analyze the hematological indexes. The most frequent 23 mutations in southern Chinese individuals were routinely measured by PCR-flow fluorenscence immunmicrobeads assay. Sanger sequencing was used to detect the other variants of β-globin gene (HBB). RESULTS: In 463 cases, a total of 7 cases with HBB:c.*233G>C variant were detected, among them 4 cases carried other pathogenic variants of HBB gene (2 cases were in trans, 2 cases were in cis), who had typical hematological characteristics of mild β-thalassemia, and 3 cases also carried abnormal hemoglobin variation, but did not have hematological characteristics of β-thalassemia. CONCLUSION The study shows that HBB:c.*233G > C variant has no obvious genetic effect and should be a benign polymorphism.

OBJECTIVE: To evaluate the efficacy and safety of salvianolate in elderly patients with unstable angina pectoris (UAP). METHODS: A prospective double-blind randomized placebo-controlled multicenter trial in elderly patients with UAP from 13 third-grade class-A hospitals in China was performed. A total of 318 patients were randomly allocated in a 1:1 ratio to an experimental group (160 patients) and a control group (158 patients). The experimental group was treated with salvianolate for 14 days on the basis of conventional medicine, and the control group was given a placebo for 14 days with the same criteria. Follow-up was lasted 28 days in both groups. The primary endpoint was biweekly frequency of angina pectoris attacks. The secondary endpoints included biweekly dosage of nitroglycerin, the Seattle Angina Questionnaire, angina pectoris severity and duration, myocardial injury markers, high-sensitivity C-reactive protein (hs-CRP) and N-terminal pro-B-type natriuretic peptide (NT-proBNP), as well as major adverse cardiovascular events (MACEs). Safety was assessed according to adverse events and serious adverse events. RESULTS: Baseline characteristics were similar between treatment groups. Compared with those in the control group, the frequency of biweekly angina attacks (2.92 vs . 4.08, P=0.025), the biweekly dosage of nitroglycerin, as well as the severity and duration of angina attacks (P<0.01) were reduced by salvianolate. The Seattle Angina Questionnaire score was also significantly improved in the experimental group than in the control group (P<0.05). No significant differences were observed between the two groups with respect to the incidence of MACEs. Salvianolate was well tolerated. CONCLUSIONS Salvianolate appear to have efficacy and well tolerated for elderly patients with UAP. [ClinicalTrials.gov identifier: NCT03037047].

【Objective】 To examine a potential correlation between corneal biomechanical properties with lamina cribrosa thickness.【Methods】Thirty-two patients with POAG，20 with NTG，15 with OHT and 26 healthy controls were included in the cross- sectional study. The parameters of corneal biomechanical properties and lamina cribrosa thickness were compared among POAG，NTG，OHT and healthy subjects by mixed-model analysis of variance（ANOVA）. Spearman′ s coefficient of rank correlation analysis was used to assess the association between parameters of deformation response and clinical factors. 【Results】 The Cronbach′ s α of lamina cribrosa thickness was 0.911，and ICC was more than 0.8. Laminar thickness was thinner in the POAG and NTG groups than in the OHT group and Normal group（P < 0.05）. There were no significant differences between OHT and normal groups（P = 0.653）. Correlation analysis showed that LCT and some important corneal biomechanical properties had significant correlation （P = 0.000）. 【Conclusions】 LCT showed different characteristic in glaucoma，and it may be an important factor for glaucoma progression. LCT and corneal biomechanical properties showed significant correlation ，and corneal biomechanical properties may be used to evaluate the biomechanical properties of optic nerve.

PURPOSETo investigate effects of neuro-immuno-modulation on wound healing by observing changes of cytokines and hypothalamic-pituitary-adrenal (HPA) axis hormones in acute stress reaction in rats with wound and combined local radiation injury.

METHODSSixty female Wistar rats (weighting 200 ± 20 g) were randomly divided into normal control group, wound group and combined wound-local radiation (CWR) group (25 Gy local radiation post wound), 20 rats in each group. Contents of IL-1β, IL-6 and IFN-γ and IL-4 in serum were measured and changes of adrenocorticotropic hormone (ACTH) and glucocorticoid (GC) in serum were analyzed by using enzyme-linked immunosorbent assay and radioimmunologic assay, respectively at different time points post wound and radiation.

RESULTS(1) The level of IFN-γ, one of the Th1 cell cytokines increased significantly at 14 d post CWR, which was markedly higher than that in control group and wound group. However, the level of IL-4, IL-1β and IL-6, one of the Th2 cell cytokines, did not show obvious change. (2) Ratio of Th1/Th2 (IFN-γ/IL-4) in wound group and CWR group increased significantly at 7 d after wound and radiation, which suggested that Th1/Th2 balance drifted to Th1 immune response. The ratio of Th1/Th2 in wound group returned to the normal level up to 14 d after the wound and radiation, while the Th1/Th2 ratio in CWR group increased persistently and was much higher than that in control and wound groups. (3) Level of serous ACTH and GC in CWR group increased at 3 d post wound and radiation, and among them, level of GC showed statistically significant increase, which was much higher than that in control and wound groups.

CONCLUSIONLevel of serous neurohormone GC in rats increased significantly immediately after wound and radiation; while the level of IFN-γ showed significant increase only up to 14 d after wound and radiation, and the Th1/Th2 imbalance sustained till 28 d post wound and radiation. In order to reduce acute damage caused by CWR, organic immune system and nerve system showed up a marked regulate effects simultaneously and mutually. Nonetheless, the excessive stress induced by CWR causes disturbance of immunoregulation, which is one of the key reasons for delayed wound healing in CWR.
