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.

Objective:To evaluate the reliability and validity of Chinese version of Ureteral Stent-Related Symptom Questionnaire (USSQ) so as to provide a scientific tool for the symptom assessment of patients with indwelling ureteral stents.Methods:Following the translation principle of Brislin, the cultural adjustment of the questionnaire was completed according to the process of literal translation of the scale, back translation, expert committee discussion and pre-experiment, and the Chinese version of USSQ was formed. Inpatients with ureteral stents in the Urology Departments of 3 ClassⅢ Grade A hospitals in Urumqi from April 2018 to February 2019 were selected as research objects, and 485 questionnaires were collected by analyzing and testing the items and reliability and validity of the questionnaire.Results:Finally, 462 valid questionnaires were collected. The analysis results of the project suggested that the two items of S1 and S2 in the Chinese version of USSQ in the field of sexual life could be deleted ( P>0.05) , however, considering the rationality of the structure of the questionnaire, S1 should be retained. Cronbach's α coefficient of the questionnaire was 0.923, Cronbach's α coefficient of the six dimensions of urinary symptoms, physical pain, total health status, work performance, sexual life and additional problems was 0.703 to 0.918, retest reliability was 0.885, retest correlation coefficient of the six dimensions was 0.338 to 0.849 ( P<0.05) , and half reliability was 0.628. The content validity of the questionnaire was 0.887. Through exploratory factor analysis, the cumulative variance contribution rate of the nine principal factors was 68.995%. In the correlation analysis, except for the correlation coefficients in the field of sexual life and other fields were from 0.014 to 0.101 ( P>0.05) , the correlation coefficients in other dimensions were from 0.406 to 0.629 ( P<0.01) . The test results of criterion validity showed that the correlation coefficients of each dimension of the questionnaire with International Prostate Symptom Score (IPSS) , Incontinence Quality of Life Scale (I-QOL) and The 12-Item Short Form Health Survey (SF-12) were from 0.35 to 0.49 ( P<0.01) . Conclusions:In addition to the field of sexual life, the Chinese version of USSQ has good reliability and validity in the evaluation of symptoms in other fields, which can provide a basis for the investigation and improvement of related symptoms in patients with indwelling ureteral stents in China.

Objective To explore the developmental characteristics of white matter volume in autism spectrum disorder (ASD) children longitudinal.Methods From May 2011 to September 2014,37 ASD children (ASD group)and 27 developmental delays (DD) children (control group) were treated at the Child Mental Health Research Center,Nanjing Brian Hospital Affiliated of Nanjing Medical University,and the children whose age,gender and developmental quotient matched with the ASD children were scanned by structure magnetic resonance imaging (sMRI) at the age of 2-3 years old and 4-5 years old respectively.Region of interest (ROI) technology was adopted to investigate the change of the cerebrum white and the sub-lobes structure white matter volume with time.Then the correlation between clinical symptoms and brain white matter volume changes was analyzed.Results Among the 2-3 years old,compared with the control group,the white matter volume of the total brain[(383 521.84 ±6 427.57) mm3 vs.(364 014.06 ±6 856.97) mm3],the left cerebral hemisphere [(191 609.35 ± 3 206.60) mm3 vs.(181 695.89 ± 3 389.54)mm3],temporal lobe [(41 860.49 ±816.38) mm3 vs.(39 444.18 ± 834.85) mm3] and the right temporal lobe [(21 312.79 ± 414.07) mm3 vs.(20 084.22 ± 412.13) mm3] were significantly larger in the ASD group,and the differences were statistically significant (all P ＜ 0.05).With the analysis of covariance with age or the total brain volume as the covariate,the differences disappeared(all P ＞ 0.05).Among the 4-5 years old,compared with the control group,the white matter volumes of the total brain[(417 651.42 ± 6 443.86) mm3 vs.(394 317.27 ± 6 404.86)mm3],left cerebral hemisphere [(208 714.16 ±3 214.61) mm3 vs.(197 192.82 ±3 262.02) mm3],right cerebral hemisphere [(208937.26±3242.09) mm3 vs.(7 124.45 ±3 193.13) mm3],frontal lobe [(107 107.46±1 681.99) mm3 vs.(100 326.19 ± 1 883.24) mm3],left frontal lobe [(54 569.63 ± 846.85) mm3 vs.(51 177.25 ±979.09) mm3],right frontal lobe [(52 537.83 ± 841.99) mm3 vs.(49 148.94 ±928.31) mm3],temporal lobe [(45 189.75 ± 833.29) mm3 vs.(42 487.73 ± 786.27) mm3],left temporal lobe [(22 204.21 ±411.77) mm3 vs.(20 922.90 ± 418.46) mm3],and right temporal lobe [(22 985.54 ± 426.93) mm3 vs.(21 564.83 ± 378.78) mm3]were significantly larger in the ASD group,and the differences were statistically significant (all P ＜ 0.05).With the analysis of covariance with age as the covariate,the differences still existed (all P ＜ 0.05).With the analysis of covariance with the total brain volume as the covariate,the differences disappeared (all P ＞ 0.05).For longitudinal analysis,there was a significant difference in the white matter volume between the whole brain,left cerebral hemisphere,right cerebral hemisphere,frontal lobe,left frontal lobe,fight frontal lobe,temporal lobe,left temporal lobe,right temporal lobe and the differences were statistically significant (F =5.521,5.533,5.459,5.830,5.800,5.723,4.857,4.418,5.159,all P ＜0.05).There was a positive correlation between the changes of the volume of whole brain,the white matter volume in the whole brain,bilateral cerebral hemisphere,frontal lobe,parietal lobe,right parietal lobe and Childhood Autism Rating Scale (r =0.367,0.343,0.321,0.349,0.296,0.308,0.351,all P ＜ 0.05).Conclusions Among the 2-3 years old,the white matter volume of the brain regions have been increased significantly in ASD.Among the 4-5 years old,the increase of the white matter volume of the brain regions implicated more widely which mainly concentrated in the frontal and temporal lobe in ASD.The severity of the clinical symptoms of ASD may be associated with the white matter volume of the total brain,bilateral cerebral hemisphere,frontal lobe,parietal lobe and right parietal lobe.

Objective To investigate the effect of dexmedetomidine pretreatment on hippocampal endoplasmic reticulum stress-induced cell apoptosis after asphyxial cardiac arrest-resuscitation in rats. Methods A total of 60 pathogen-free male Sprague-Dawley rats, aged 6-8 weeks, weighing 200-300 g, were divided into 3 groups (n= 20 each) by using a random number table: control group (C group), as-phyxial cardiac arrest-resuscitation group ( CA group) and dexmedetomidine pretreatment group ( Dex group). The anaesthetized rats were intubated with a 16G tracheal catheter which was connected to a rodent ventilator for mechanical ventilation. Cardiac arrest was induced by clamping the tracheal tube at the end of the exhalation until systolic blood pressure decreased to 25 mmHg lasting for 5 min, and then resuscitation was started. At 5 min before cardiac arrest, dexmedetomidine 4. 0 μg∕kg was intravenously injected in group Dex, and the equal volume of normal saline was given instead in C and CA groups. Rats were sacri-ficed at 6 h after successful resuscitation, brain tissues were removed for determination of wet to dry weight ratio ( W∕D ratio), and hippocampal tissues were obtained for examination of the pathological changes (with a light microscope) and ultrastructure (with an electron microscope) and for determination of cell ap-optosis (by TUNEL), expression of CCAAT∕enhancer-binding protein homologous protein (CHOP) and ac-tivated transcription factors (ATF4) and X-4 box binding protein 1 (XBP1) mRNA (by real-time polymer-ase chain reaction) and expression of CHOP, Bcl-2, Bax and caspase-3 (by Western blot). The apoptosis rate was calculated. Results Compared with group C, W∕D ratio of brain tissues was significantly in-creased, the apoptosis rate of hippocampal tissues was decreased, the expression of XBP-1, ATF4 and CHOP mRNA was up-regulated, the expression of CHOP, Bax and caspase-3 was up-regulated, and the expression of Bcl-2 was down-regulated in CA and Dex groups (P<0. 05). Compared with group CA, W∕D ratio of brain tissues was significantly decreased, the apoptosis rate of hippocampal tissues was decreased, the expression of XBP-1, ATF4 and CHOP mRNA was down-regulated, the expression of CHOP, Bax and caspase-3 was down-regulated, the expression of Bcl-2 was up-regulated (P<0. 05), and the pathological changes were significantly attenuated in group Dex. Conclusion The mechanism by which dexmedetomi-dine pretreatment mitigates brain injury after asphyxial cardiac arrest-resuscitation may be related to inhibi-ting cell apoptosis induced by endoplasmic reticulum stress in rats.

A simple assay for detection of phospholipase C (PLC) activity was developed based on a fluorescence liposome probe using the Liss Rhod PE-loaded phospholipid liposomes.The liposome probe was prepared by the coassembly of 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) and fluorescent lipid (Liss Rhod PE).The probe showed very low background fluorescence due to fluorescence self-quenching effect of Liss Rhod PE.As the PLC enzyme selectively digested lipid, the Rhod fluorescence was recovered from its quenched state, leading to the sensitive detection of PLC.This assay provided a limit of detection (at a signal-to-noise ratio of 3) of 2 U/L for PLC.In the presence of PLC inhibitor, the fluorescent response of the sensor for PLC decreased, indicating that the assay could also be used for screening PLC inhibitors.

Objective To explore the clinical efficacy and safety of Hydromorphone combined with Propofol therapy in painless gastroscopy combined with colonoscopy examination in elder patients.Methods Sixty-one patients aged 65-80 years underwent a painless gastroscopy combined with colonoscopy examination in the Affiliated Tumor Hospital of Zhengzhou University from June 2015 to January 2016.The patients were randomly divided into the Hydromorphone combined with Propofol group (Group H,n=31) and the Fentanyl combined with propofol group (Group F,n=30).Results The levels (H vs F group) of VAS at 5,15,30 min after anesthetic recovery were lower in H group thanin F group[(2.4±0.5) vs (3.4±0.6),(2.0±0.5) vs (3.2±0.6),(1.6±0.4) vs (2.6±0.7) respectively,(all P＜0.05)],and those of ramsay sedation scores at 5,15,30,45,and 60 min after anesthetic recovery were lower in H group than in F group[(2.6 ± 0.4) vs (3.3 ± 0.5),(2.3±0.5) vs (2.9±0.4),(2.1±0.3) vs (2.6±0.3),(1.9±0.3) vs (2.2±0.3),(1.8±0.3) vs (2.0±0.3) (all P＜0.05)] respectively.Additionally,the incidence rates (H vs F group) of nausea and vomit (3.2％ vs.26.7％),respiratory depression (0.0％ vs.33.3％) and restlessness (6.5％ vs.30.0％) within 60 min after anesthetic recovery were lower in the group H than in the group F (all P＜ 0.05).However,there were no statistical differences in the indexes of postoperative gastrointestinal function between two groups (all P＞0.05).Conclusions The clinical efficiency of hydromorphone combined with propofol used in painless gastroscopy combined colonoscopy examination is favourable and safe without increasing postoperative adverse reactions in elder patients.Hydromorphone combined with propofol is superior to fentanyl combined with propofol as a general intravenous anesthesia.

Objective To investigate the difference of Wechsler's cognitive test and its influencing factors in first-episode depression patients with and without sleep disorder.Methods 156 patients with de-pression were divided into two groups according to their sleep conditions,including sleep disorder group(n=77)and non-sleep disorder group(n=79).Wechsler Intelligence Scale(WAIS)and Wechsler Memory Scale(WMS)were used to assess the cognitive function,while Hamilton Depression Scale(HAMD-17) were used to assess depressive symptoms.Results (1)Sleep disorders group had lower scores on verbal IQ (95.51±16.45),performance IQ(90.94±13.87),FIQ scores(92.48±15.49)than those in the non-sleep disorder group((105.59±15.20),(96.19±13.62),(101.20±14.70)respectively),the differences were statistically significant(P<0.05).Sleep disorder group had lower scores in immediate memory(10.47 ± 3.88),short-term memory(49.87±14.35)and memory quotient(87.90±18.25)than those in the non-sleep disorder group((11.86±3.47),(56.52±13.03),(97.27±18.76)respectively),the differences were statisti-cally significant(all P<0.05).(2)Multivariate linear regression analysis showed that education and age ex-plained 24% of variance in verbal IQ(F=21.258,P<0.01).Education,sleep disorder factors explained 12.9% of variation in performance IQ(F=9.825,P<0.01).Education,sleep disorder factors explained 22.3% of variance in total IQ(F=22.847,P<0.01).Education,age,sleep disorder factors explained 28.4%of variation in short-term memory(F=23.850,P<0.01).Education and age explained 20.4% of variation in immediate memory(F=18.10,P<0.01).Education and sleep disorder factors explained 21.9% of variation in memory quotient(F=26.162,P<0.01).Conclusion The intelligence and memory impairment in first-epi-sode depression patients with sleep disorders is more serious,and the education,sleep disorder and age are the most important factors.

Objective To evaluate the effects of dexmedetomidine pretreatment on extracellular sig?nal?regulated kinase ( ERK) pathway during acute lung injury in a rat model of liver transplantation. Meth?ods Sixty male Sprague?Dawley rats, weighing 235-250 g, were divided into 4 groups ( n=15 each) u?sing a random number table: sham operation group (group S), liver transplantation group (group LT), low?dose dexmedetomidine pretreatment group ( group LD ) and high?dose dexmedetomidine pretreatment group ( group HD) . In LT, LD and HD groups, the model of orthotopic liver transplantation was estab?lished, and the operation time was about 4 h. Dexmedetomidine 2?5 and 5?0μg·kg-1 ·h-1 were intrave?nously infused for 1 h starting from 1 h prior to clipping the hepatic artery and portal vein in LD and HD groups, respectively. The rats were sacrificed after the end of operation, and the lungs were removed for determination of wet to dry weight ratio ( W∕D ratio) , cell apoptosis and expression of ERK mRNA, ERK, phosphorylated ERK ( p?ERK) , Bcl?2 and Bax in lung tissues and for examination of the pathological chan?ges ( with light microscope) and ultrastructure of lung tissues ( with transmission electron microscope) . The
injured alveolus rate ( IAR) , apoptosis index ( AI) and ratio of Bcl?2 to Bax expression ( Bcl?2∕Bax ratio) were calculated. Results Compared to group S, the W∕D ratio, IAR, AI, expression of ERK?1 mRNA, ERK?2 mRNA, p?ERK, Bcl?2 and Bax and Bcl?2∕Bax ratio were significantly increased in LT, LD and HD groups ( P<0?05) . Compared to group LT, the W∕D ratio, IAR and AI were significantly decreased, the expression of ERK?1 mRNA, ERK?2 mRNA, p?ERK and Bcl?2 and Bcl?2∕Bax ratio were significantly increased, and the expression of Bax was significantly down?regulated in LD and HD groups (P<0?05). Compared to group LD, the W∕D ratio, IAR and AI were significantly decreased, the expression of ERK?1 mRNA, ERK?2 mRNA, p?ERK and Bcl?2 and Bcl?2∕Bax ratio were significantly increased, and the ex?pression of Bax was significantly down?regulated in group HD ( P<0?05) . The pathological changes of lung tissues were significantly attenuated in LD and HD groups as compared with group LT, and in group HD as compared with group LD. Conclusion The mechanism by which dexmedetomidine pretreatment mitigates cell apoptosis during acute lung injury is related to activation of ERK pathway in a rat model of liver trans?plantation.

Objective To investigate the inhibitory effects of IBI302 on experimental choroidal neovascularization (CNV).Methods Affinity of IBI302 to vascular endothelial growth factor (VEGF) family cytokines (including VEGF-A165,VEGF-A121 and placental growth factor PlGF) and complements (C3b,C4b) was determined by enzyme-linked immunosorbent assay (ELISA).The antagonist effect of IBI302 on VEGF was measured by proliferation,migration and tube formation tests of human umbilical vein endothelial cells (HUVEC).The anti-complement activity of IBI302 was measured by hemolysis test mediated by complement classical pathway and alternative pathway.Rhesus laser-induced CNV model was divided into 5 groups including model control group,bevacizumab group,IBI302 0.25 mg group,IBI302 0.50 mg group and IBI302 1.25 mg group.Fluorescein angiography and optical coherence tomography were performed on these monkeys at 14 and 28 days after drug delivery to observe the fluorescein leakage area and retinal thickness.The aqueous VEGF concentration was measured at 29 days after drug delivery.Results IBI302 showed good affinity to VEGF-A165,VEGF-A121 and PlGF,as well as C3b and C4b.IBI302 significantly inhibited the proliferation,migration and tube formation of HUVEC induced by VEGF-A165.IBI302 inhibited the hemolysis induced by complements obviously.At 14 and 28 days after drug delivery,the area of fluorescein leakage and retinal thickness in IBI302 0.25 mg group,IBI302 0.50 mg group,IBI302 1.25 mg group were reduced.The differences of the area of fluorescein leakage and retinal thickness in three IBI302 groups were not significant (P＞0.05).At 29 days after drug delivery,the VEGF concentration in the aqueous of rhesus monkey in bevacizumab group [(38.644 ± 6.521) pg/ml] was decreased than that in model control group [(94.203± 17.360) pg/ml],the difference was significant (P＜ 0.05).The VEGF concentration in the aqueous of rhesus monkey in three IBI302 groups were less than 31.300 pg/ml.Conclusion IBI302 inhibited experimental CNV through blocking the activity of VEGF and complement.
