Aim To investigate the therapeutic effects of a newly developed Tadalafil tablets on pathological myocardial hypertrophy induced by abdominal aortic constriction(AAC)in rats,as well as its influence on the activation of the NF-κB signaling pathway in myo-cardial cells.Methods SD rats were randomly divid-ed into 4 groups:the sham operation group(Sham),the model group(AAC),the tadalafil new tablet treat-ment group(N-Tad,5 mg·kg-1),and the positive control drug treatment group(Cialis,10 mg·kg-1g).The AAC model group and treatment group rats under-went blunt dissection and constrictive ligation of the abdominal aorta at the left renal artery branch point during surgery,while the Sham group rats only had their arteries separated without any constrictive liga-tion.Rats in the treatment groups received either N-Tad or Cialis via gavage three days after modeling,while rats in the sham group and the model group re-ceived physiological saline daily for 8 weeks.Small an-imal ultra-high-resolution echocardiography and hemo-dynamic assessment were applied to evaluate left ven-tricular function in each group of rats,and the calcula-tion of the left ventricular mass index was conducted.By employing Western blot and RT-PCR.we assessed the impact of this treatment on the expression of the hy-pertrophy factor atrial natriuretic peptide(ANP),phosphorylated NF-κB p65 protein(p-NF-κB p65),and phosphorylated IκB-α in the left heart tissue of rats and in H9c2 cardiomyocytes.Results Compared to the Sham group,the AAC rats exhibited a significant decrease in left heart function,an increase in left ven-tricular mass index,and a notable increase in ANP and p-p65 expression in the left heart tissue(P＜0.05).Both N-Tad and Cialis treatments could significantly enhance left ventricular function,decrease left ventric-ular mass index,and inhibit the expression of ANP and phosphorylated NF-κB p65 in rats with myocardial hy-pertrophy(P＜0.05).Notably,the therapeutic effect of low-dose N-Tad was comparable to that of high-dose Cialis.At the cellular level,Tadalafil significantly in-hibited the activation of the NF-κB signaling pathway and reduced the expression of associated proteins in H9c2 cardiomyocytes.Conclusions N-Tad can sig-nificantly inhibit p65 and IκB-α phosphorylation,and the activation of the NF-κB signaling pathway,reduce ANP expression,and improve pathological myocardial hypertrophy,as well as mitigate left heart function damage caused by abdominal aortic constriction.

Objective: To investigate the psychometric properties of the balance self-efficacy (BSE) scale in people with stroke. Methods: This is a cross-sectional study held in a university-based rehabilitation center. Sixty- three people with stroke and 30 healthy older adults were included from the community dwelling. The people with stroke underwent the following assessments in a random order: the BSE, Fugl-Meyer Assessment of Lower Extremity (FMA-LE), muscle strength of plantar flexors and dorsiflexors, Montreal Cognitive Assessment, Berg Balance Scale, Limit of Stability (LOS), Foot and Ankle Ability Measure (FAAM), 12-Item Short Form Survey (SF-12) version 2, and Oxford Participation and Activities Questionnaire (Ox-PAQ). The healthy older adults were assessed with BSE. Results: The BSE scale demonstrated good test-retest reliability (intraclass correlation coefficient= 0.796) with minimal detectable change at a 95% confidence interval of 433.74 and cut-off score of 1,225, which best differentiated between people with stroke and healthy older adults. The BSE score was significantly correlated with the FMA-LE score, muscle strength of the affected side ankle dorsiflexor and plantar flexor, LOS parameter, FAAM, SF- 12, and Ox-PAQ scores. Conclusion The BSE scale is a reliable clinical tool with good test-retest reliability. The BSE scores were significantly correlated with other outcome measures that assess motor functions, balance, and quality of life. It is a simple and easy-to-administer outcome measure for assessing BSE in people with stroke.

Objective:To investigate the association between visceral adipose tissue (VAT) thickness in early pregnancy and the risk of gestational diabetes mellitus (GDM).Methods:Based on the Qingdao Women and Children Health Cohort, pregnant women in the first trimester (11-13 +6 weeks of gestation) were enrolled in this cohort study between May 2019 and October 2022. The VAT was measured in first trimester and determined as the distance from the inner margin of the rectus abdominis muscle to the anterior wall of the great artery using multi-functional color ultrasound. The 75 g oral glucose tolerance test (OGTT) results were followed up at 24-28 weeks and the participants were divided into GDM group and non-GDM group. The pregnant women were divided into 4 groups according to the VAT quartile. Log-binomial model and linear regression model were used to analyze the association between VAT and GDM/blood glucose. Results:A total of 3 686 pregnant women were included in this study, the mean age of participants was (30.56±4.05) years and 722 were diagnosed with GDM, with an incidence of 19.6%. The log-binomial regression model results showed that compared with VAT thickness Q1 (VAT<14.70 mm), the GDM risk in Q3 (21.65≤VAT≤29.69 mm) and Q4 (VAT ≥29.70 mm) increased by 34% [ RR(95% CI): 1.34 (1.08-1.67)], and 61% [ RR(95% CI): 1.61 (1.30-2.00)], respectively. Among women with gestational age<35 years old, compared with VAT thickness Q1, the risk of GDM increased by 42% in Q3 [ RR(95% CI): 1.42 (1.22-1.65)] and 70% [ RR(95% CI): 1.70 (1.46-1.98)] in Q4, whereas no associations were found in women with gestational age ≥35 years old ( P>0.05). The association between VAT and GDM risk was only found in pregnant women with pre-pregnancy BMI <24.0 kg/m 2, and the GDM risk increased by 57% [ RR(95% CI): 1.57 (1.22-2.04)] in Q3 and 65% [ RR(95% CI): 1.65 (1.24-2.19)] in Q4 compare with Q1. The results of multiple linear regression analysis showed that VAT was positively correlated with fasting blood glucose, 1-hour blood glucose after 75 g OGTT and 2-hours blood glucose after 75 g OGTT (all Pfor trend<0.001). Conclusion:High VAT thickness in early pregnancy is an independent risk factor for GDM, and the GDM risk increases with the raising of VAT depth.

Aim To investigate the effect of total glu-cosides of paeony on inflammatory injury and TLR4/NF-κB/NLRP3 pathway in autoimmune thyroiditis(AIT)rats.Methods The experiment was divided into control group,model group,total glucosides of pae-ony(TGP),TLR4 inhibitor group and TGP+TLR4 ag-onist group,with 10 animals in each group.Except for the control group,the rats in other groups were subcu-taneously injected with thyroglobulin and Freund's ad-juvant to induce the AIT rat model.After six weeks of administration,thyroid histopathological changes were observed using hematoxylin-eosin(HE)staining;ser-um levels of TPOAb,TgAb,TSH,T3,T4,TNF-α,INF-γ,IL-1 β and IL-1 β were detected by enzyme-linked immunosorbent assay(ELISA);TLR4/NF-κB/NLRP3 pathway mRNAs and proteins expression in thyroid tis-sues were detected by RT-qPCR and Western blot.Re-sults Compared with the control group,the thyroid follicular epithelium of rats was significantly damaged,and the serum levels of TPOAb,TgAb,TSH,T3,T4,TNF-α,INF-γ,IL-1 β and IL-1 β increased(P＜0.01).The expression of TLR4/NF-κB/NLRP3 path-way mRNAs and proteins increased in the model group(P＜0.01).Compared with the model group,the damage of thyroid follicular epithelium was alleviated,and the serum levels of TPOAb,TgAb,TSH,T3,T4,TNF-α,INF-γ,IL-1 β and IL-1 β were reduced(P＜0.01),the expression of TLR4/NF-κB/NLRP3 path-way mRNAs and proteins were down-regulated in the TGP group and TLR4 inhibitor group(P＜0.01).Compared with TGP group,the damage of thyroid follic-ular epithelium was aggravated,and the levels of serum TPOAb,TgAb,TSH,T3,T4,TNF-α,INF-γ,IL-1 β and IL-1 β were elevated(P＜0.05 or P＜0.01),the pro-tein expressions of TLR4/NF-κB/NLRP3 pathway mR-NAs and proteins were up-regulated in TGP+TLR4 ag-onist group(P＜0.05 or P＜0.01).Conclusions TGP may play a protective role in thyroid by inhibiting the TLR4/NF-κB/NLRP3 pathway and improving the inflammatory injury of thyroid tissues.

Objective Based on the theory of five circuits and six qi,the characteristics of circuit-qi indicators of the date of birth of hospitalized patients with pneumonia of Shaoyin-disease syndrome were explored.Methods The data collection was conducted in 422 hospitalized patients with pneumonia of shaoyin-disease syndrome admitted to the Department of Classical Chinese Medicine,Fangcun Hospital of Guangdong Provincinal Hospital of Chinese Medicine from January 20,2012 to June 30,2022.And then statistical analysis was performed for circuit-qi indicators of the date of birth of the patients.Results The goodness of fit by chi-square test showed that there were statistically significant differences in the distribution of the heavenly-stem year,earthly-branch year,yearly circuit,recombinant yearly circuit,predominant qi,and sitian-zaiquan(circuit qi of the first and second half of a year)at birthdate of hospitalized patients with pneumonia of shaoyin-disease syndrome(P＜0.05 or P＜0.001).And the results indicated that a higher risk of suffering from pneumonia of shaoyin-disease syndrome existed in the population born in the heavenly-stem ji year and earthly-branch chou year,in the yearly circuit being deficient earth circuit,in the recombinant yearly circuit being wind,in the predominant qi being taiyin damp earth,and in the sitian-zaiquan being taiyin damp earth and taiyang cold-water.Conclusion There is a correlation between the incidence of pneumonia of shaoyin-disease syndrome and the circuit-qi indicators of the date of birth of the patients,and the pathogenesis of circuits and qi at birth date is probably related with yang deficiency of spleen and kidney,and cold interweaved with dampness.

Objective To compare the clinical efficacy and pregnancy outcomes of CO2 laser and loop electrosurgical excision procedure(LEEP)surgery in the treatment of cervical high-grade squamous intraepithelial lesion(HSIL)in women of childbearing age.Methods Patients with cervical HSIL of appropriate reproductive age(20-34 years old)who underwent satisfied colposcope,subsequently treated with laser or LEEP between Jan 2019 and Dec 2021 in Obstetrics and Gynecology Hospital,Fudan University were collected.All the patients were interpreted as transformation zone(TZ)type 1/2,and colposcopy biopsy diagnosed as cervical high-grade squamous intraepithelial lesion(HSIL)and received laser or LEEP according to the physician's advice and the patient's wishes.The effectiveness of the two surgeries was evaluated,and postoperative cytology,HPV result,and colposcopic pathology were compared.We monitored the surgical pregnancy rate,pregnancy complications,and pregnancy results after the surgery.Results A total of 566 cases,including 233 laser cases and 333 LEEP cases,were enrolled.There was no significant difference between the two groups in terms of preoperative cytology,HPV distribution,or the length of cervical canal.After 6 months of surgery,91.5%of patients who underwent laser therapy and 86.9%of those who underwent LEEP had normal cytology.The histology cure rate was 91.5%and the HPV conversion rate was 74.6%in both groups.The results of cytology,HPV,and colposcopic pathology had no significant difference between the two groups.The length of postoperative cervical canal was significantly longer in laser group than that in LEEP group[(29.09±3.15)mm vs.(27.05±3.84)mm,P<0.001].There was no statistically significant difference in postoperative pregnancy rate and pregnancy outcome between the two groups.Conclusion Laser ablation and LEEP produce comparable effects pregnancy outcomes in cervical HSIL patients with TZ types 1 and 2,while LEEP has pathologic feedback,so its misdiagnosis of invasive cancer reduce.

Objective To explore the safety and management mode of hysteroscopy in three different modes:outpatient,daily and inpatient.Methods The quality control data of patients who underwent hysteroscopic surgery in Hysterscopy Centre,Obstetrics and Gynecology Hospital,Fudan University from Jan 2019 to Dec 2021 were collected through the electronic information system of the hospital and the monthly quality control report of hysteroscopy center.The amount of surgery,the proportion of grade Ⅳsurgery,the analysis of operation types,the indicator including complications,and unanticipated secondary surgery were retrospectively analyzed.Results From 2019 to 2021,5 162 outpatient hysteroscopic patients,15 331 daily hysteroscopic patients and 5 942 inpatient hysteroscopic patients were admitted in our hospital.The age of inpatient hysteroscopic patients was significantly older than those of outpatient and daily patients(P<0.001).In the past three years,the proportion of daily hysteroscopy gradually increased,and the proportion of inpatient hysteroscopy gradually decreased(P<0.001).The total percentage of grade Ⅳ hysteroscopic surgery was 12.9%,in which inpatient was higher than daily,and daily was higher than outpatient(P<0.001).The incidence of complications and accidents during hysteroscopy was 0.117%(31/26 435),including 17 cases of uterine perforation,7 cases of hysteroscopy failure,3 cases of excessive intraoperative bleeding,2 cases of fluid overload,1 case of intestinal injury,and 1 case of anesthesia accident.The incidence of hysteroscopy in outpatient,daily and inpatient were 0.020%(1/5 162),0.137%(21/15 331)and 0.151%(9/5 942)respectively.Conclusion Hysteroscopy in outpatient,daily and inpatient are all safe and reliable.Outpatient and daily hysteroscopy can improve the efficiency of medical services,which has gradually become a trend.
