This study is to explore the effects of quercetin (QUE) on the 3 week-old mice ovarian development and relative hormone levels. The 3 week-old mice were exposed to QUE (45, 25, and 5 mg x kg(-1) x hd(-1)) by gavage for 50 days. The estrous cycle during 50 days and the changes of hormone level such as FSH, LH, etc were monitored. Moreover, the ovaries were removed after sacrifice. The organ index was measured, and the ratios of different stages of follicles were analyzed by HE staining. Furthermore, the proportion of PCNA positive cells during all stages was detected by immunohistochemistry. The results showed that QUE could increase body weight of mice and reduce the anogenital distance (AGD) to some extent, and was able to disrupt mice's estrous cycle, but it could not extend or reduce the cycle regularity. It increased ovarian organ index with a dose-dependent manner. The proportion of the primordial follicle and secondary follicles rose obviously, and that of mature follicles', atretic follicles' and corpus luteums' reduced, while primordial follicle had no change. Immunohistochemistry analysis showed that QUE could effectively increase the percentage of proliferating cells in all kinds of follicles. Serum hormone assay showed that there were significant changes of FSH and LH levels. In summary, QUE showed an estrogen-like effect on mice's ovarian development. The weight of ovary, the proportion of all kinds of follicles, the development of ovarian cells and the level of plasma hormone in mice were altered obviously by oral administration of QUE.

Objective To establish the reference ranges of the spatial angles among cardiac chambers and great vessels in second and third trimester fetuses measured by spatiotemporal image correlation (STIC).Methods Volume images of 352 normal fetuses from 20 to 38 weeks of gestation were recruited in the study.An off-line analysis of acquired volume datasets was carried out with multiplanar mode.Parameters measured included angles between:(1) the 4-chamber view and the left ventricular long axis view; (2) the left ventricular long axis view and main pulmonary artery; and (3) the ductal arch and aortic arch.The relationships between above-mentioned angles and gestational age were assessed by correlation and regression analysis.Results The angle between the 4-chamber view and the left ventricular long axis view (range:55.7° - 35.7°,mean:45.7° ± 5.12°) was uncorrelated with gestational age (r = 0.03,P = 0.51).In contrast,the angle between the left ventricular long axis view and main pulmonary artery,and the angle between the ductal arch and aortic arch were correlated with gestational age (P ＜ 0.001),and the correlation coefficient was - 0.53 and 0.57 respectively.The best-fit exponential curve regression equations of the angle between the left ventricular long axis view and main pulmonary artery was:Y = 154- 4.24X +0.05X2 ,and the angle between the ductal arch and aortic arch was:Y = - 20.8 + 2.65X - 0.37X2.Conclusions The angles among cardiac chambers and great arteries of fetuses from 20 to 38 weeks of gestation can be quantitatively measured by STIC.The reference ranges provide a reliable quantitative standard to estimate the spatial relationships of the cardiac large arteries of fetuses,which may be clinically useful in prenatal screening congenital heart disease.

Objective To investigate the effect of Osthole on memory function of sleep deprivation(SD) mice. Methods Forty-eight male mice were randomly divided into 4 groups;normal control group(NC group ), large platform control group(TC group),sleep deprivation group(M group)and Osthole group(Ost group). The model of SD in mice was estabished by using improved multi platform method. The ability of learning and memory was tested by using Morris water maze test and pathological changes of hippocampal neurons in mice were observed by HE staining. The serum,hippcampus malondialdehyde(MDA)contents and superoxide dismutase(SOD)activity, so as the hippocampus No content,were detected. Results Compared with NC group and TC group,the escape la-tency of M group increased significiantly and the number of crossing platform decreased significantly. There were in-creased levels hippocampus tissue,serum MDA level,hippocampal SOD activity and NO content. After supplemen-tation of Osthole,the escape latency significantly shortened in mice. The number of crossing platform was increased while the contents of MDA both in hippocampus and serum were decreased,and the SOD activity in hippocampus re-turned to normal. However,the level of NO in hippocampus was not decreased. Conclusion Osthole can protect the memory function of SD mice by reducing the the damage of hippocampal neurons through antioxidant stress.

Objective To express UL148 RNA of human cytomegalovirus (HCMV) clinical strains in vitro and to study its functions. Methods Urine of a newborn with HCMV infection was inocula-ted into human embryo lung cells. HCMV clinical strain was isolated and identified by multiplex PCR. UL148 gene was amplified and cloned into pGEM-T-Easy plasmid after double enzyme digestion. A recombi-nant plasmid was constructed and located at the downstream of the T7 promoter. The recombinant plasmid was identified by electrophoresis of the recombinant plasmid,PCR product and double enzyme product. Se-quencing analysis was used for final confirmation. UL148 was transcribed into RNA by 32P labeling. Post-translational modification sites were analyzed by bioinformatics method based on UL148 sequence characteris-tics. Results The clinical strain of HCMV was obtained in vitro. Electrophoresis and sequencing analysis confirmed the successful construction of the recombinant plasmid. UL148 RNA was transcribed in vitro by T7RNA polymerase. Post-translational modification sites showed that UL148 gene contained one cell adhe-sion sequence, one legume lectins beta-chain signature, two N-myristoylation sites, one casein kinase Ⅱphosphorylation site,seven protein kinase C phosphorylation sitse, one cAMP/cGMP-dependent protein ki-nase phosphorylation site, two N-glycosylation sites and one transmembrane region. Conclusion UL148 gene might encode a viral adhesion molecule involving in the signal transduction in host cells.

Objective To evaluate the effectiveness of spatio-temporal image correlation with M-mode display ( STIC-M ) in monitoring fetal left ventricular systolic function in fetuses with congenital heart disease(CHD) . Methods Five hundred and thirty-six normal fetuses and 34 fetuses with CHD( 29 without hydrops and 5 with hydrops) were involved in the study . Left ventricular fractional shortening ( LVFS) was measured using STIC-M . The data of normal fetuses was used to construct reference ranges of LVFS for assessment of fetuses with CHD . Results The LVFS of the normal fetuses [ range :26 .8％ - 42 .9％ , mean :( 34 .9 ± 4 .1) ％ ] was negatively correlated with gestational age ( r = - 0 .16 , P < 0 .001) . Compared with the normal controls ,LVFS was significantly decreased in CHD fetuses with hydrops ( P < 0 .001) . However ,there was no significant difference in LVFS between normal controls and CHD fetuses without hydrops ( P > 0 .05) . Conclusions STIC-M is a new method that can be used to measure LVFS to evaluate fetal ventricular systolic function . The fetal ventricular contractile function of CHD fetuses without hydrops may not be damaged or is in compensation stage . The fetuses with cardiac hydrops generally become lower .

Objective To evaluate the clinical and pathological features of patients with prostate cancer who were diagnosed by single positive core biopsy and treated by radical prostatectomy (RP).Methods Between July 2012 and June 2016,164 patients with prostate cancer diagnosed by single positive core biopsy underwent RP.The mean age was 66.3 years old (ranged 41-82 years old),and the mean PSA level was 12.3 ng/ml (ranged 0.6-59.5 ng/ml).The biopsy Gleason score showed 6 scores in 113 cases,3 + 4 =7 scores in 21 cases,4 + 3 =7 scores in 18 cases,≥8 scores in 12 cases.Clinical stage was cT1 in 71 cases,cT2 in 92 cases,and cT3 in 1 case.The patients were divided into subgroups according to age,preoperative PSA level,biopsy Gleason score and clinical stage,and the pathological results were compared among these subgroups.Results Of the 164 patients,67 cases had Gleason score ≤ 6,52 cases Gleason score 3 + 4 =7,24 case Gleason score 4 + 3 =7,and 11 cases Gleason score ≥ 8.Ten patients had pT0 disease according to the RP specimen,3 had extraprostatic extensions,5 had seminal vesicle invasions,and 24 had positive surgical margins.Compared to the biopsy,the Gleason score of RP specimens was higher in 53 cases,concordant in 77 cases,and lower in 24 cases.There was no significant difference in the postoperative pathological features between the age group ＜ 70 years and the group ≥ 70 years.Compared with PSA ＜ 10 ng/ml,the likelihood of postoperative Gleason score ＞ 7 was significantly increased in PSA ≥10 ng/ml group [41.4％ (36/87) vs.66.2％ (51/77),P＜0.05].When the biopsy Gleason score was divided into four groups (6,3 + 4 =7,4 + 3 =7,≥ 8),there were significant differences in postoperative pathological stages among the four groups (P ＜ 0.05),and the patients with biopsy Gleason score 6 were more likely to have no residual cancer (stage T0) when compared with other Gleason scores [8.8％ (10/113) vs.0,P =0.09].The probability of no residual cancer in clinical T1 stage patients was significantly higher than that in T2 stage [11.3％ (8/71) vs.2.8％ (2/92),P =0.02],while the probability of Gleason score upgrading was significantly lower [23.9％ (17/71) vs.39.1％ (36/92),P ＜ 0.05].Conclusions Most single core prostate cancer have clinically significant disease.The treatment plan must be evaluated individually for patients with single core prostate cancer.

Objective To investigate the prognostic value of atherogenic index of plasma(AIP)for the occurrence of major adverse cardiovascular events(MACE)in elderly patients with acute ST-segment elevation myocardial infarction(STEMI).Methods A total of 355 elderly patients with acute STEMI who received coronary interventional therapy in Department of Cardiology,Affilia-ted Hospital of Hebei University from January to May 2023 were recruited retrospectively,and fi-nally 343 of them with complete telephone follow-up data were included in this study.According to their AIP quartile level,they were divided into A1 group(＜0.212,84 cases),A2 group(0.212-0.339,87 cases),A3 group(0.339-0.434,86 cases)and A4 group(≥0.434,86 cases).The incidences of cardiac death,nonfatal myocardial infarction,ischemia-driven target vessel re-modeling and heart failure re-hospitalization were observed during 1-year follow-up.Kaplan-Meier survival curve was plotted to compare the incidence of MACE in the 4 groups.ROC curve analysis was employed to determine the predictive value of AIP.Results During 1-year follow-up,signifi-cant differences were observed in the proportions of ischemia-driven target vessel revasculariza-tion,heart failure re-hospitalization and non-fatal acute myocardial infarction among the 4 groups(P＜0.05,P＜0.01),and such difference was also seen in the cumulative survival rate among them(log rankx2=8.528,P=0.036).Multivariate Cox proportional hazards regression analysis showed that gender,hypertension,atrial fibrillation,multi-vessel disease,left main artery disease,number of stents,SYNTAX score,Killip grade,BNP,HbA1c,TC,LDL-C and HDL-C levels,and AIP were independent predictors of MACE.The AUC value of AIP in predicting MACE in elderly patients with acute STEMI was 0.855(95％CI:0.776-0.933),with a sensitivity of 66.7％and a specificity of 93.0％.When the above indicators combined together,the AUC value was 0.907(95％CI:0.954-0.987),and the sensitivity and specificity was 100.0％and 90.7％,respectively.The AUC value of combined prediction was significantly better than that of single indicator(P＜0.05).Conclusion AIP is a powerful biomarker,and can be used to predict the prognosis of elderly acute STEMI after coronary interventional therapy,and it combined with Killip grade,SYNTAX score,HbA1c,and number of stents shows better predictive efficacy.

Glutamate serves as a major excitatory neurotransmitter in the mammalian central nervous system and is stored in synaptic deft by an uptake system that is dependent on the high-affinity glutamate transporters (ETTAs),which locate in the plasma membrane of glial cells and neurons.ETTAs can rapidly terminate the action of glutamate and maintain its normal physiological functions.If the content or function of glutamate transporters is abnormal,it can result in many physiological dysfunctions.Studies have demonstrated that high-affinity glutamate transporters play an important role in the development of chronic pain,which might be a new therapeutic target for the pain.

Objective:To analyze the phenotypes and genetic etiology of microcephaly- seizures-development delay (MCSZ) syndrome.Methods:The patient was diagnosed with MCSZ syndrome in June 2018 at Shenzhen Maternity and Child Healthcare Hospital. She was the couple's first child, and the mother conceived a second child in 2020. The clinical data of the proband were retrospectively analyzed, and the bioinformatics analysis and whole-exome sequencing (WES) were performed on the proband and her parents to identify the pathogenic variants, which were further validated using Sanger sequencing. The prenatal genetic diagnosis of the second fetus was performed following the molecular diagnosis of the proband was confirmed. The clinical manifestations and pathogenesis of MCSZ syndrome were summarized by reviewing related literature.Results:(1) Case report: The patient, an eight-month-old girl, was admitted to our hospital due to microcephaly and repeated seizures. Another clinical characteristic was mental retardation. Auditory evoked potential detected moderate impairment of the left auditory nerve pathway. WES showed a compound heterozygous variation in the PNKP gene of the proband. Moreover, the pathogenic variation, c.199-10_203delinsTCTGAGGGGT, was inherited from the father, and the likely pathogenic variation, c.1505C>T(p.P502>L), was inherited from the mother, which was both de novo mutations. The compound heterozygous variation in the PNKP gene was considered genetic etiology based on the genetic testing and clinical features. Prenatal diagnosis showed that the second fetus did not inherit the PNKP gene variants from the parents and the couples chose to continue the pregnancy. A girl was born, and her psychomotor development and occipitofrontal size circumference were normal at 13 months old. (2) Literature review: 39 MCSZ syndrome cases were retrieved, including the present case and 38 cases from 12 relevant literature. The clinical characteristics were microcephaly (91.7%, 33/36), seizures (88.2%, 30/34), development delay (96.4%, 27/28), hyperactivity (25.6%, 9/39), gastroesophageal reflux (10.3%, 4/39), and hearing loss (7.7%, 3/39). Most patients' first onset of epilepsy was in infancy (96.3%, 26/27). Cranial MRI examination showed brain dysplasia in 31 cases (91.2%, 31/34). Conclusions:When the fetal head circumference is smaller than normal and is progressively reduced combined with postnatal microcephaly, epilepsy, developmental retardation, hyperactivity disorder, gastroesophageal reflux, and hearing loss, MCSZ syndrome should be considered. The prognosis varies widely, and genetic testing facilitates the early diagnosis and genetic counseling of MCSZ syndrome.
