Objective:To evaluate the reliability and validity of the Chinese version of HEMO-FISS-QoL(HF-QoL) questionnaire (HF-QoL-C) in the Chinese population with hemorrhoids.Methods:From November 2021 to November 2022, a self-constructed general information questionnaire, HF-QoL-C, and the 36-item short form health survey (SF-36), Goligher classification, and Giordano severity of hemorrhoid symptom questionnaire (GSQ) were used to conduct a questionnaire survey on 760 hemorrhoid patients in the anorectal department of six hospitals. The data was analyzed for reliability and validity using SPSS 21.0 and AMOS 26.0 software.Results:The Cronbach's α coefficient of HF-QoL-C and its dimension ranged from 0.831 to 0.960, and the split coefficient was 0.832-0.915. Four common factors were extracted through principal component exploratory factor analysis. Confirmatory factor analysis indicated acceptable structural validity( χ2/ df=8.152, RSMEA=0.097, CFI=0.881, IFI=0.881, NFI=0.867). HF-QoL-C was correlated with SF36 and GSQ( r=-0.694, 0.501, both P<0.01). There were differences in the total score and dimensional scores of HF-QoL-C between surgical and drug treated patients, different grades of Goligher classification for hemorrhoidal disease, and different ranges of hemorrhoid prolapse (all P<0.001). No ceiling effect was found in the total score and the scores of each dimension(0.3%-2.0%). There was a floor effect in both psychological function and sexual activity dimensions (16.7%, 35.1%). Conclusion:HF-QoL-C has good reliability and validity, which can be used to measure the quality of life of Chinese hemorrhoid patients.

Methods:From February 2018 to January 2022, the clinical data of 1 123 patients who underwent Starclose vascular closure device, Angio-Seal and Exoseal vascular occlusion devices and Perclose ProGlide vascular suture device at femoral artery puncture hemostasis after neuro-intervention, in the Department of Interventional Radiology (Eastern District), The First Affiliated Hospital of Zhengzhou University, were retrospectively analyzed. The patients were divided into three groups based on the intervention method: the closure group (Starclose, n=271), the occlusion group (Angio-Seal, n=327 and Exoseal, n=352) and the suture group (ProGlide, n=173). Next, the hemostatic efficacy and complications associated with the three devices were analyzed and compared. Additionally, regression analysis was conducted to identify any relevant factors that may contribute to complications. Results:Three vascular hemostatic devices demonstrated effective hemostasis and the success rate were 92.6% in the closure group (Starclose), 93.4% in the occlusion group (Angio-Seal 93.0% and Exoseal 93.8%) and 89.6% in the suture group (ProGlide). There was no statistically significant difference( χ2=3.026, P=0.388). Single or multiple complications were observed in 102 patients (9.1%), including local oozing (16 cases in the closure group, 39 cases in the occlusion group, 13 cases in the suture group), local hematoma (14 cases in the closure group, 31 cases in the occlusion group, 11 cases in the suture group), pseudoaneurysm (13 cases in the closure group, 35 cases in the occlusion group, 10 cases in the suture group), local infection (2 cases in the closure group, 3 cases in the occlusion group, 1 case in the suture group). There were no statistically significant differences ( P>0.05). Moreover, serious complications such as femoral artery occlusion, embolus shedding and permanent nerve injury weren′t observed in the three groups. Multivariate logistic regression analysis revealed that overweight ( OR=1.562,95% CI 1.023—2.385, P=0.039), femoral artery with calcified plaque ( OR=1.934,95% CI 1.172-3.189, P=0.010), combined use of multiple antiplatelet drugs ( OR=1.769,95% CI 1.103—2.839, P=0.018), use of an 8F sheath( OR=2.824,95% CI 1.406—5.671, P=0.004) and the operator′s proficiency ( OR=0.508,95% CI 0.328—0.788, P=0.002) were the independent factors influencing complications, of which the first four were identified as risk-promoting factors for complications while the operator′s rich experience and high proficiency were the protective factors. Conclusions:Three hemostatic devices demonstrate effective hemostasis and comparable rates of complications at femoral artery puncture hemostasis after neuro-intervention. Overweight, femoral artery with calcified plaque, combined use of multiple antiplatelet drugs, use of an 8 F sheath and the operator′s proficiency were independent factors influencing complications.Ojective:To investigate the efficacy and complications associated with vascular suture, closure and occlusion devices at femoral artery puncture hemostasis after neuro-intervention.

Objective:Differences between randomized controlled trial (RCT) results and real world study (RWS) results may not represent a true efficacy-effectiveness gap because efficacy-effectiveness gap estimates may be biased when RWS and RCT differ significantly in study design or when there is bias in RWS result estimation. Secondly, when there is an efficacy- effectiveness gap, it should not treat every patient the same way but assess the real-world factors influencing the intervention's effectiveness and identify the subgroup likely to achieve the desired effect.Methods:Six databases (PubMed, Embase, Web of Science, CNKI, Wanfang Data, and VIP) were searched up to 31 st December 2022 with detailed search strategies. A scoping review method was used to integrate and qualitatively describe the included literature inductively. Results:Ten articles were included to discuss how to use the RCT research protocol as a template to develop the corresponding RWS research protocol. Moreover, based on correctly estimating the efficacy-effectiveness gap, evaluate the intervention effect in the patient subgroup to confirm the subgroup that can achieve the expected benefit-risk ratio to bridge the efficacy-effectiveness gap.Conclusion:Using real-world data to simulate key features of randomized controlled clinical trial study design can improve the authenticity and effectiveness of study results and bridge the efficacy-effectiveness gap.

Objective:Randomized controlled trials (RCT) usually have strict implementation criteria. The included subjects' characteristics of the conditions for the intervention implementation are quite different from the actual clinical environment, resulting in discrepancies between the risk-benefit of interventions in actual clinical use and the risk-benefit shown in RCT. Therefore, some methods are needed to enhance the extrapolation of RCT results to evaluate the real effects of drugs in real people and clinical practice settings.Methods:Six databases (PubMed, Embase, Web of Science, CNKI, Wanfang Data, and VIP) were searched up to 31 st December 2022 with detailed search strategies. A scoping review method was used to integrate and qualitatively describe the included literature inductively. Results:A total of 12 articles were included. Three methods in the included literature focused on: ①improving the design of traditional RCT to increase population representation; ②combining RCT Data with real-world data (RWD) for analysis;③calibrating RCT results according to real-world patient characteristics.Conclusions:Improving the design of RCT to enhance the population representation can improve the extrapolation of the results of RCT. Combining RCT data with RWD can give full play to the advantages of data from different sources; the results of the RCT were calibrated against real-world population characteristics so that the effects of interventions in real-world patient populations can be predicted.

OBJECTIVE:
To investigate the changes in percentage of GATA3+ regulatory T (Treg) cells in patients with allergic rhinitis (AR) and mouse models.
METHODS:
The nasal mucosa specimens were obtained from 6 AR patients and 6 control patients for detection of nasal mucosal inflammation. Peripheral blood mononuclear cells (PBMC) were collected from 12 AP patients and 12 control patients to determine the percentages of Treg cells and GATA3+ Treg cells. In a C57BL/6 mouse model of AR, the AR symptom score, peripheral blood OVA-sIgE level, and nasal mucosal inflammation were assessed, and the spleen of mice was collected for detecting the percentages of Treg cells and GATA3+ Treg cells and the expressions of Th2 cytokines.
RESULTS:
Compared with the control patients, AR patients showed significantly increased eosinophil infiltration and goblet cell proliferation in the nasal mucosa (P < 0.01) and decreased percentages of Treg cells and GATA3+ Treg cells (P < 0.05). The mouse models of AR also had more obvious allergic symptoms, significantly increased OVA-sIgE level in peripheral blood, eosinophil infiltration and goblet cell hyperplasia (P < 0.01), markedly lowered percentages of Treg cells and GATA3+ Treg cells in the spleen (P < 0.01), and increased expressions of IL-4, IL-6 and IL-10 (P < 0.05).
CONCLUSION
The percentage of GATA3+ Treg cells is decreased in AR patients and mouse models. GATA3+ Treg cells possibly participate in Th2 cell immune response, both of which are involved in the occurrence and progression of AR, suggesting the potential of GATA3+ Treg cells as a new therapeutic target for AR.

ObjectiveTo investigate the clinical value of DR corneal suture ring localization and CT 3D reconstruction localization of orbital foreign bodies. MethodsRetrospective analysis was performed on patients (51 cases) suspected of ocular foreign bodies admitted to our hospital from January 2016 to December 2020 At the same time, DR corneal suture ring localization and CT three-dimensional reconstruction localization of orbital foreign bodies were performed, and the detection rate of foreign bodies by the two methods was calculated to analyze the location of ocular foreign bodies. ResultsThere were 38 cases of intraorbital foreign body identified by DR corneal suture ring localization method, and 46 cases of intraorbital foreign body identified by CT three-dimensional reconstruction localization method. The accuracy of CT three-dimensional reconstruction localization method was 90.20%, which was higher than that of DR corneal suture ring localization method 74.51% (P<0.05). Intraocular foreign bodies in 23 cases could be distinguished by DR corneal suture ring localization, and 25 cases by CT 3D reconstruction localization. The maximum diameter of intraocular foreign bodies that could be distinguished by CT 3D reconstruction localization was (2.65±0.14) mm. The diameter of intraspherical foreign body was (2.94±0.36) mm (P<0.05) lower than that which could be distinguished by DR corneal suture ring localization method. The results of DR corneal suture ring localization of orbital foreign body showed no difference compared with the results of CT 3D reconstruction localization (P>0.05). Forty cases of high density images inside and outside the eye could be clearly distinguished by CT 3D reconstruction. By using DR corneal suture ring localization method, 23 cases were confirmed to be intraocular high-density shadows, and 15 cases could not be confirmed to be intraocular high-density shadows (P < 0.05). ConclusionsFor the location of intraorbital foreign bodies, CT three-dimensional reconstruction can be used as a conventional method for locating ocular foreign bodies with high resolution and accuracy, and can detect fine metal particles inside the eyeball. Meanwhile, for a few small foreign bodies in the iris root, ciliary body and lateral suspension ligament, it is necessary to locate orbital foreign bodies with DR corneal suture ring.

Objective:To explore the stent apposition and safety of Neuroform EZ and Enterprise 2 stents in treatment of symptomatic intracranial atherosclerotic stenosis (sICAS), and their influencing factors for in-stent restenosis.Methods:A total of 143 sICAS patients treated by Enterprise 2 stents (implanted 143 Enterprise 2 stents, E2 group) and 202 patients treated by Neuroform EZ stents (implanted 202 Neuroform EZ stents, EZ group) were selected from Department of Interventional Radiology, First Affiliated Hospital of Zhengzhou University from January 2017 to January 2022. Stent apposition was evaluated based on reconstructive images of high-resolution flat detector CT. The complications 30 d after surgery and during 6-24 months of follow-up were recorded. Based on DSA or CTA 6 months after surgery, the patency of the two stents was evaluated. Univariate analysis and multivariate Logistic regression analysis were used to determine the independent risk factors for in-stent restenosis.Results:(1) Forty-nine patients had incomplete stent apposition (ISA) after stent release: 24 patients with ISA in E2 group (16.8%, 24/143; 15 of type I and 9 of type II) and 25 with ISA in the EZ group (12.4%, 25/202, 11 of type I and 14 of type II) were found, without statistical difference ( χ 2=1.334, P=0.248); however, ISA incidence in the EZ group (19.0% and 10.3%) was significantly lower than that in the E2 group (41.4% and 25.6%) when the diameter ratio of anterior and posterior vessels of the stenosis lesions≥1.30 or the angle of stent≥75° ( χ 2=4.228, P=0.040; χ 2=4.531, P=0.033). (2) Within 30 d of stenting, 17 patients developed neurological dysfunction-related complications: 8 patients in EZ group and 9 in E2 group were noted, without significant difference ( P=0.324). Clinical follow-up was obtained in 317 patients, and 20 patients developed long-term stroke associated with responsible lesion vessels: 12 patients in EZ group and 8 in E2 group were noted, without significant difference ( P=0.995). (3) Totally, 298 patients received imaging follow-up 6 months after surgery, and 65 patients developed in-stent restenosis: 36 patients in EZ group and 29 in E2 group were noted, without significant difference ( χ 2=0.309, P=0.578). Multivariate Logistic regression analysis showed that diabetes ( OR=2.714, 95% CI: 1.437-5.126, P=0.002), stent apposition ( OR=3.435, 95% CI: 1.223-9.652, P=0.019), lesion stenosis length ( OR=1.176, 95% CI: 1.065-1.300, P=0.001) and immediate postoperative residual stenosis ( OR=1.038, 95% CI: 1.004-1.074, P=0.029) were independent influencing factors for in-stent restenosis. Conclusions:Enterprise 2 and Neuroform EZ stents have high stent apposition and safety in sICAS treatment, but in cases with large diameter ratio of the anterior and posterior vessels of the stenosis lesions (diameter ratio≥1.30) or large angle of the stent (≥75°), Neuroform EZ stent has better stent apposition. Patients with diabetes, ISA, long lesion stenosis or high residual stenosis may trend to have in-stent restenosis.
