Objective To investigate the therapeutic efficacy of artesunate(AS)on polycystic ovary syndrome(PCOS)in mice and explore the potential mechanism primarily.Methods Twenty-five female C57BL/6J mice were randomly divided into Control group,model group(PCOS group),low-and high-dose AS groups(AS15 and AS30 groups)and metformin group(Met group).In addition to the Control group,the mouse model of PCOS was established by subcutaneous injection of dehydroepiandrosterone(DHEA,60 mg/kg)following by a high-fat diet for 21 d.After modeling,AS of 15 and 30 mg/kg was intraperitoneally injected into the mice of the AS 15 and AS30 groups,respectively,and 200 mg/kg Met was given to those of the Met group by gavage,once per day,for 6 weeks.ELISA was used to detect serum testosterone(T),fasting insulin(FINS),luteinizing hormone(LH)and follicle-stimulating hormone(FSH),and the LH/FSH ratio was calculated.The levels of fasting blood glucose(FBG),triglyceride(TG)and total cholesterol(TC)were detected by automatic biochemical analyzer,and the homeostasis model assessment of insulin resistance(HOMA-IR)was calculated.The estrous cycle was observed,and HE staining was performed for pathological changes in the ovary and uterus.Immunofluorescence assay was employed to measure the expression of p-eIF2α,ATF4 and CHOP in the ovarian tissue.After steroidogenic human granulosa-like tumor cell line KGN were exposed to 100 μmol/L DHEA to simulate the hyperandrogen environment of PCOS,and then treated with 5 and 10 μg/mL AS for 24 h,the protein levels of endoplasmic reticulum stress signaling pathway was detected by Western blotting.Results Compared with the Control group,the PCOS mice had disturbed estrous cycle,polycystic changes in the ovaries,and significantly increased serum T level and LH/FSH ratio(P＜0.05),and obviously elevated HOMA-IR,TC and TG levels in terms of metabolism(P＜0.01).The expression levels of p-eIF2α,ATF4 and CHOP were notably up-regulated in the ovarian granulosa cells of PCOS mice and KGN cells after DHEA exposure(P＜0.05).Additionally,AS treatment attenuated the pathological changes of ovary and uterine expression,decreased the serum T level and the LH/FSH ratio(P＜0.05),and reduced HOMA-IR,TC and TG levels(P＜0.05)when compared with the PCOS mice.Moreover,the expression levels of p-eIF2α,ATF4 and CHOP were significantly down-regulated after AS treatment in both ovarian granulosa cells of PCOS mice and KGN cells(P＜0.05).Conclusion AS significantly improves glycolipid metabolic disorder and reproductive dysfunction in PCOS mice,which may be associated with its suppressing endoplasmic reticulum stress by inhibiting the PERK/eIF2α/ATF4/CHOP pathway.

Objective To explore the therapeutic mechanism of maggot for psoriasis-like lesions in mice from the perspective of immune stress and complement activation regulation.Methods Thirty-six male C57BL/6 mice were randomly divided into control group,model group,maggot(1.25%,2.5%,and 5%)groups,and Benvitimod(1%)group.Psoriasis-like lesions were induced by application of imiquimod cream,and the severity of skin lesions was assessed using the modified Psoriasis Area and Severity Index(MPASI)score.Auricular swelling of the mice was observed,and histopathological changes of the skin lesions were examined with HE staining.Scratching behavior of the mice was observed and the spleen index was calculated.Toluidine blue staining was used to detect mast cells in the skin lesions,and serum levels of IgG,IgM,the complements CH50,C1s,C3,C3a,C5 and C5a,and the inflammatory factors IL-23,IL-17A and TNF-α were determined with ELISA.Results In mice with imiquimod-induced psoriasis-like skin lesions,treatment with the maggot at the 3 doses significantly decreased MPASI score,alleviated auricular swelling and pathologies in the skin lesions,reduced scratching behaviors,spleen index,and the number of mast cells in the lesions.Treatment with high-dose maggot significantly lowered serum levels of IgG,C1s,C3a,C5a,IL-23,IL-17A and TNF-α and the levels of C1s,C3,C3a,C5 and C5a in the lesion tissue,and increased serum levels of CH50,C3,and C5.The therapeutic effect of maggot showed a dose-effect dependence.Conclusion Maggot can alleviate psoriasis-like skin lesions in mice by inhibiting immune stress and complement activation.

Objective:To construct an estimating equation to accurately reflect the aging phenomenon of the glomerular filtration rate(GFR).Methods:Healthy subjects receiving physical examinations at the First Affiliated Hospital of Nanjing Medical University between January 2017 and April 2018 were included in the study, and the aging phenomenon of renal function indicators such as serum creatinine(Scr)was used as the reference standard to evaluate the accuracy of four Scr-based GFR equations during GFR aging, including the full age spectrum(FAS)equation, the Chronic Kidney Disease Epidemiology Collaboration(CKD-EPI)equation, the Osaka equation and the Xiangya equation.Results:Of 37 636 individuals receiving physical examinations, 6 534 met the criteria specified in this study.Scr, serum urea nitrogen, serum uric acid, and serum albumin showed a significant aging phenomenon( H=191.640, 196.693, 83.271, 414.585, P<0.001 for all).The GFR estimated by the four equations all decreased with aging, but the starting point and rate of decline were significantly different.The GFR aging phenomenon estimated by the FAS equation was closer to the trend of renal function indicators. Conclusions:The FAS equation may be more applicable to healthy people to understand the aging phenomenon of GFR.

Objective To retrospectively analyze the periprocedural and postprocedural antithrombotic therapy regimens for patients undergoing percutaneous left atrial appendage closure(PLAAC)at Nanjing Drum Tower Hospital(hereinafter referred to as"the hospital")and their association with prognosis,and to provide a basis for antithrombotic therapy in clinical practice for such patients.Methods We systematically collected medical records of non-valvular atrial fibrillation patients underwent PLAAC treatment from January 2018 to January 2022 at our hospital.We recorded basic patient information,preoperative left atrial appendage(LAA)thrombus screening,and antithrombotic regimens,and analyzed the incidence of bleeding and thrombotic events during the periprocedural period and up to 12 months postprocedure.Results A total of 96 patients underwent PLAAC,with 86 included in the final analysis.Eight patients had LAA thrombus detected by transesophageal echocardiography before the procedure,and all thrombi resolved after one month of extended antithrombotic therapy.There was one bleeding event in the continuous anticoagulation group during the periprocedural period,while no bleeding events occurred in the interrupted anticoagulation group.Within one year postprocedure,11 patients(18.0%)in the continuous anticoagulation group and 4 patients(16.0%)in the interrupted anticoagulation group experienced bleeding events.All patients adhered to anticoagulant therapy as prescribed for the first three months postprocedure;between three to six months postprocedure,33.7%of patients received dual antiplatelet therapy(DAPT),and 29.1%discontinued therapy;between six to twelve months,47.7%of patients received single antiplatelet therapy(SAPT)and 48.8%discontinued therapy.During the one-year follow-up,there was one case each of device-related thrombus,ischemic stroke,and cerebral hemorrhage,indicating a low overall incidence of adverse events.Conclusion In the real-world setting,the individualized antithrombotic regimens provided by physicians at the hospital,both periprocedurally and postprocedurally,were reasonable and consistent with guidelines.However,poor medication adherence was a significant issue among patients.It is recommended that clinical pharmacists actively engage in pharmacotherapy monitoring and enhance medication education to improve medication adherence.

Objective To observe the motion sickness among undergraduates during their first maritime practice,and to explore the relationships between gender,traditional Chinese medicine(TCM)constitution,psychological factors,susceptibility to motion sickness and nautical motion sickness.Methods A total of 120 sophomore students were selected by simple random sampling.The Constitution Classification and Determination Scale of TCM,Beck depression inventory-short form(BDI-SF),state trait anxiety inventory(STAI)and modified motion sickness susceptibility questionnaire(mMSSQ)were used for a questionnaire survey among the students.Seasickness discomfort was assessed by Graybiel scale when they first entered the rough sea.Results A total of 104 trainees completed the questionnaire.The physical constitution was mainly characterized by damp-heat,phlegm dampness,Qi deficiency,and Yang deficiency.There was no significant difference in the incidence of motion sickness among the students with different constitutions(P<0.05).Depressi on was found in 16 people(15.38%),and depression was highly correlated with the susceptibility to motion sickness and anxiety(all P<0.01).Fifty-six students(53.85%)were highly susceptible to motion sickness.All the students felt discomfort when they first entered the rough sea,and the discomfort in females was significantly stronger than that in males(P<0.01).Motion sickness occurred in 54 students,the incidence of motion sickness in females was higher than that in males(P<0.01),and the incidence of motion sickness in the students with depression was higher than that in the students without depression(P<0.01).Gender,Yang deficiency constitution,degree of depression,and susceptibility to motion sickness were significantly correlated with the motion sickness(P<0.05),and could be used as predictors of motion sickness.Conclusion There is a high incidence of motion sickness among college students during their first maritime practice.More attention should be paid to female students,and to students with Yang deficiency constitution,negative emotions(depression and anxiety)and high susceptibility to motion sickness.

At present, the teaching objects of clinical pharmacists have gradually changed from merely university students to complex and diverse groups including clinical pharmacist interns and others. However, the traditional teaching model cannot be tailored to different groups. In addition, it increases the burden of clinical pharmacists while not ensuring teaching quality. This study aims to classify teaching objects according to their characteristics, so as to provide individualized knowledge and service. Compared with the traditional way of teaching, this new method may make teaching more relevant and reduces the teaching load of teachers, which is of great significance to the training of clinical pharmacy personnel.

Objective:To evaluate the influence of sex on age-related changes in the glomerular filtration rate(GFR)in healthy individuals.Methods:A retrospective survey was performed.A total of 36 911 healthy subjects, of whom 43.61%(16 096 cases)were men, were enrolled and divided into six age groups: 18-29, 30-39, 40-49, 50-59, 60-69, and ≥70 years old.The estimated glomerular filtration rate(eGFR)was evaluated by the full age spectrum(FAS)equation.General linear regression analysis was used to calculate the annual decline rate of eGFR, and differences between the sexes in the same age group were evaluated using analysis of covariance.The chi-square test was used to compare the proportions of subjects with different eGFR levels between the sexes.Results:Regardless of sex, body mass index(BMI), systolic blood pressure(SBP)and fasting blood glucose(FBG)all increased gradually with age, while diastolic blood pressure(DBP)increased initially and then turned downward.The means of above results in men were generally higher than those in women of the same age.Before the age of 40, the levels of eGFR in men and women were relatively stable, with the mean eGFR in women higher than that in men[(121.98±16.77)ml·min -1·1.73 m -2vs.(111.01±13.36)ml·min -1·1.73 m -2, t=-53.793, P=0.000]; After the age of 40, eGFR decreased with age in both sexes, and the decline rate of eGFR in women was faster than that in men before the age of 70.Men had generally higher mean serum creatinine(Scr), blood urea nitrogen(BUN)and serum uric acid(UA)than women.With the increase of age, BUN levels increased gradually in men and women, but Scr levels started to increase after the age of 40 only in women and did not show a clear increase in men. Conclusions:There are sex-related differences with aging, as measured with many parameters.Young and middle-aged women have significantly higher eGFR than men of the same age, but eGFR declines faster with aging in women.
