Objective To explore the changes in neural activity in patients with type 2 diabetes mellitus(T2DM)and their corre-lation with executive function,and to analyze the neural mechanisms underlying the decline in executive function in T2DM patients.Methods Thirty-one T2DM patients(T2DM group)and thirty-two healthy controls(HC)(HC group)matched for body mass index(BMI)underwent resting-state functional magnetic resonance imaging(rs-fMRI)scans and N-back task tests were included.Differ-ences in the amplitude of low-frequency fluctuation(ALFF),regional homogeneity(ReHo),and seed-based functional connectivity(FC)between the two groups were compared,and partial correlation analyses were performed between the difference results and N-back task performance.Results The T2DM group showed prolonged reaction time(RT)in the 1-back and 2-back tasks.T2DM patients exhibited increased ALFF in the bilateral caudate nucleus,left medial superior frontal gyrus,and right postcentral gyrus,as well as elevated ReHo in the right putamen.FC analysis revealed significant alterations in FC between the caudate nucleus,putamen,and multiple brain regions in T2DM patients,with some of these FC changes significantly correlated with RT and accuracy(ACC)in the N-back task.Conclusion The decline in executive function in T2DM patients may be associated with abnormal neural activity in brain regions such as the striatum,salience network,and frontoparietal control network.FC further decreases under increased cognitive load.These findings provide evidence for the study of the neural mechanisms of executive function impairment in T2DM patients.

Objective:To analyze the relevant studies on fertility concerns intervention programs for breast cancer survivors of childbearing age, and identify the specific content, outcome indicators and intervention effects of intervention, in order to provide reference for clinical staff to implement relevant intervention.Methods:According to the research method of scope review, the studies on the fertility concerns with breast cancer patients of childbearing age in China National Knowledge Infrastructure, WanFang, VIP, China Biomedical Literature Database, CINAHL, PubMed, Cochrane Library, Web of Science etc. were searched. The search period was from database establishment to May 9, 2024. The included literature was classified and analyzed.Results:A total of 12 articles were included, 9 were randomized controlled trials, 2 were self-controlled before and after studies, and 1 was a prospective cohort study. Fertility concerns intervention programs included group fertility counseling centered on couples, fertility support based on a multidisciplinary team collaboration model, and fertility management based on "Internet + reproductive health". The duration of intervention was usually 4 or 24 weeks. The intervention had different effects on the level of fertility concerns, psychological state and marital status.Conclusions:At present, the intervention programs for fertility concerns of breast cancer survivors of childbearing age reflect the importance, professionalism, immediacy and interactivity, but China is in the initial stage, and there are still shortcomings in multidisciplinary teams, fertility referral system, and Internet platform construction.

Objective To explore the polymorphism and distribution of apolipoprotein E(ApoE)gene in patients with hyperlipidemia.Methods A total of 370 hyperlipidemia patients diagnosed at Hangzhou Ninth People's Hospital from October 2023 to June 2024 were selected.Gene polymorphism was detected in the blood samples of the patients using fluorescence polymerase chain reaction,and the distribution of gene polymorphism among different genders and age groups within this population was compared.Results ①The polymorphism distribution of the two genetic loci(ApoE 388T＞C and ApoE 526C＞T)in the studied sample population conforms to Hardy-Weinberg equilibrium,indicating that it is representative of the population;②Among the 370 patients,the distribution of the ApoE gene was as follows:E3/E3(66.49％),E3/E4(20.27％),E2/E3(8.65％),E2/E4(1.89％),E2/E2(1.35％),and E4/E4(1.35％).The proportion of the patient population carrying the E4 allele was about 1.88 times higher than that of those carrying the E2 allele;③The distribution differences of ApoE gene polymorphism were not related to the patients'gender and age(P＞0.05).Conclusion The distribution of ApoE gene polymorphism among hyperlipidemia patients at a hospital in Hangzhou is uneven and is not related to gender or age groups.Therefore,it is recommended to prioritize the detection of ApoE gene in patients before using statin medications to assess treatment effectiveness.

Objective:To explore the relationship between serum anti-Müllerian hormone (AMH) level and related clinical factors in healthy females, and establish and validate equation of correlation between age and serum AMH level for healthy females.Methods:From March 2015 to December 2016, a total of 602 females who measured serum AMH level in Department of Nuclear Medicine, the Second Affiliated Hospital of Soochow University were retrospectively enrolled. All cases had relatively complete clinical data, and were divided into healthy group (484 cases, 20-52 years) and case group (118 cases, 20-42 years; patients with menstrual disorders). Relationships between serum AMH level and estradiol (E2), tesosterone (T), follicle stimulating hormone (FSH), luetinizing hormone (LH), body mass index (BMI) of healthy group were analyzed by Spearman rank correlation. Kruskal-Wallis rank sum test was used to analyze the relationship between history of gestation and serum AMH level. Serum AMH level of health group was processed to establish predictive equation for serum AMH level. Internal ( n=27) and external ( n=37) validation group were chosen from healthy females with serum AMH level measured to validate the equation, and signed rank test was used to analyze the data. Difference between serum AMH level in case group and healthy group with corresponding age was explored by independent-sample t test. Results:Serum AMH levels were positively correlated with E2 and T ( rs values: 0.263, 0.334, both P<0.001), and negatively correlated with FSH, LH, BMI ( rs values: from -0.515 to -0.110, all P<0.005). Predictive equation was established as LogAMH=-1.208+ 0.1×age-0.000 042×age 3 ( R2=0.735, P<0.001). No statistically significant difference was found between real serum AMH levels and calculated serum AMH levels in the internal and external validation groups ( z values: -1.62 and -1.52, both P>0.05). Females in case group ( n=118) and control group ( n=446) were divided into two sub-groups respectively (<35 years and ≥35 years), and serum AMH levels of case group were lower than those of control group with corresponding age ( t values: 18.64, 11.70, both P<0.001). Conclusions:In healthy females, serum AMH level is related to some clinical data. The equation between serum AMH level and age established in the study may provide reference for clinical diagnosis and treatment.

ObjectiveTo investigate the effect of Shengjiang Tonglong prescription hollow suppository on rats with prostate hyperplasia， and the effect of the proteins related to phosphoinositide 3-kinase/protein kinase B （PI3K/Akt） signaling pathway in the prostate， thus exploring the mechanism of Shengjiang Tonglong prescription hollow suppository in the treatment of rats with prostate hyperplasia. MethodTen SD male rats were randomly selected from 60 SD male rats to form a sham operation control group， and the rest rats were subcutaneously injected with testosterone propionate for 4 consecutive weeks after castration to induce the rat model of prostatic hyperplasia. According to the random number table method， the 50 rats were randomly divided into a model group， a finasteride group （0.45 mg·kg^-1）， and three high， middle， and low-dose Shengjiang Tonglong prescription hollow suppository groups （3.98， 1.99， 0.99 g·kg^-1）， with ten rats in each group. After castration for 7 d， the sham operation control group and the model group used the blank hollow suppositories， and the finasteride group and the Shengjiang Tonglong prescription hollow suppository groups used the corresponding hollow suppositories. The drugs were given to the rats by anal plugs continuously for 28 d. The rats were then killed， and the prostate tissues were separated and weighed to observe the effects of drugs on the prostate index of rats in each group. The hematoxylin-eosin （HE） staining was used for the pathological observation of the prostate tissues. The level of dihydrotestosterone （DHT） was detected by enzyme-linked immunosorbent assay （ELISA）. Western blot was used to detect the expression levels of PI3K/Akt signaling pathway protein， B-cell lymphoma-2 （Bcl-2）， cysteine aspartate-specific protease-3 （Caspase-3）， Bcl-2-associated X protein （Bax）， and αB-crystallin （CRYAB） protein in the prostate tissues. ResultAs compared with the sham operation control group， the protein expression levels of prostate index， DHT level， CRYAB， Bcl-2， PI3K， and Akt in the model group were increased， and the protein expression levels of Caspase-3 and Bax were decreased （P<0.05， P<0.01）. As compared with the model group， the prostate index in the high-dose Shengjiang Tonglong prescription hollow suppository group was decreased （P<0.05）， and the level of DHT and the protein expression levels of CRYAB， Bcl-2， PI3K， and Akt in the prostate of the Shengjiang Tonglong prescription hollow suppository groups were decreased， and the protein expression levels of Caspase-3 and Bax were increased （P<0.05， P<0.01）. ConclusionShengjiang Tonglong prescription hollow suppository decreases the expression of CRYAB protein， negatively regulates the PI3K/Akt signaling pathway， down-regulates the level of DHT and the protein expression levels of Bcl-2， PI3K， and Akt， and up-regulates the protein expression levels of Caspase-3 and Bax， thereby inhibiting cell proliferation and promoting cell apoptosis， which plays a therapeutic role in the benign prostate hyperplasia （BPH）. The high-dose Shengjiang Tonglong prescription hollow suppository significantly improves prostatic hyperplasia in rats.

The integrity of the blood-brain barrier (BBB) is important for maintaining the function of the central nervous system. Its leakage can occur prior to structural changes. At present, the role of BBB leakage abnormalities in the occurrence and development of cognitive impairment has attracted attention, and it has been found that Alzheimer's disease and vascular cognitive impairment are related to BBB leakage abnormalities. This article reviews the pathophysiology of BBB leakage in Alzheimer's disease and vascular cognitive impairment.

Purpose: Cervical cancer is one of the most fatal diseases among women in under-developed countries. To improve cervical cancertreatment, discovery of new targets is needed. In this study, we investigated the expression of NUP210, miR-22, and Fas in cervicalcancer tissues and their functions in cell cycle regulation. Materials and Methods: We detected and compared the expression levels of NUP210, miR-22, and Fas in cervical cancer tissueswith paired normal tissues using immunohistochemistry, Western blot, and real-time quantitative polymerase chain reaction.NUP210 was knocked down in HeLa cells via lentivirus, followed by cell cycle and proliferation analysis. Using a luciferase reporterassay, we explored the link between miR-22 and NUP210. We overexpressed miR-22 in HeLa cells and analyzed cell cycle and proliferationfunction. We then overexpressed miR-22 in NUP210 knockdown cells to explore the connection between Fas and miR-22-NUP210 signaling. Results: We found that NUP210 was overexpressed in cervical cancer patients. Knocking down NUP210 restored cell apoptosisand proliferation. We confirmed miR-22 as a regulator of NUP210 and verified that miR-22 was inhibited in cervical cancer development.We also found that restoring miR-22 expression could induce cell apoptosis. Finally, we found that miR-22-regulated expressionof NUP210 could alter Fas expression and, in turn, elicit cell cycle arrest and proliferation. Conclusion miR-22 in cervical cancer is downregulated, resulting in NUP210 overexpression and inhibition of Fas-induced cellapoptosis.
