In this comprehensive review, we delve into the evolution of drug delivery systems in reproductive medicine with a focus on the emerging role of exosomes, a class of extracellular vesicles. Exosomes offer unique advantages in overcoming these challenges due to their inherent biocompatibility, stability, and ability to facilitate targeted delivery. This review provides a detailed examination of exosome biogenesis and their function in cellular communication, setting the stage for understanding their potential as drug delivery vehicles. We explore the mechanisms through which exosomes can be loaded with small molecule drugs and the benefits they offer over synthetic nanoparticles. The review highlights groundbreaking case studies that illustrate the successful application of exosome-mediated drug delivery in reproductive health, including enhancing fertility treatments, supporting gamete and embryo development, and facilitating maternal-fetal communication. This study aims to provide a precise understanding of how exosomal drug delivery can revolutionize treatments for reproductive health disorders, paving the way for future therapeutic applications. Lastly, we touch upon the promising therapeutic implications of exosomal delivery for proteins and genes, offering a window into future treatments for reproductive health disorders.

Background: s/Aims: Sarcomatoid hepatocellular carcinoma (HCC) is a rare histological subtype of HCC characterized by extremely poor prognosis; however, its molecular characterization has not been elucidated. Methods: In this study, we conducted an integrated multiomics study of whole-exome sequencing, RNA-seq, spatial transcriptome, and immunohistochemical analyses of 28 paired sarcomatoid tumor components and conventional HCC components from 10 patients with sarcomatoid HCC, in order to identify frequently altered genes, infer the tumor subclonal architectures, track the genomic evolution, and delineate the transcriptional characteristics of sarcomatoid HCCs. Results: Our results showed that the sarcomatoid HCCs had poor prognosis. The sarcomatoid tumor components and the conventional HCC components were derived from common ancestors, mostly accessing similar mutational processes. Clonal phylogenies demonstrated branched tumor evolution during sarcomatoid HCC development and progression. TP53 mutation commonly occurred at tumor initiation, whereas ARID2 mutation often occurred later. Transcriptome analyses revealed the epithelial–mesenchymal transition (EMT) and hypoxic phenotype in sarcomatoid tumor components, which were confirmed by immunohistochemical staining. Moreover, we identified ARID2 mutations in 70% (7/10) of patients with sarcomatoid HCC but only 1–5% of patients with non-sarcomatoid HCC. Biofunctional investigations revealed that inactivating mutation of ARID2 contributes to HCC growth and metastasis and induces EMT in a hypoxic microenvironment. Conclusions We offer a comprehensive description of the molecular basis for sarcomatoid HCC, and identify genomic alteration (ARID2 mutation) together with the tumor microenvironment (hypoxic microenvironment), that may contribute to the formation of the sarcomatoid tumor component through EMT, leading to sarcomatoid HCC development and progression.

Objective: To investigate the trends in mortality and life loss of gastric cancer in Wenzhou City, Zhejiang Province from 2014 to 2023, so as to provide the evidence for formulating the prevention and control strategy for gastric cancer. Methods: The surveillance on causes of death data of permanent residents in Wenzhou City were collected through the Wenzhou Chronic Disease Monitoring and Management Information System from 2014 to 2023. The crude mortality of gastric cancer was calculated, and standardized by the data from the Sixth Chinese National Population Census in 2010. The life loss were measured using potential years of life lost (PYLL) and rate of potential years of life lost (PYLLR). The characteristics of mortality and life loss of gastric cancer in different genders and age groups were described. The trends in mortality and PYLLR of gastric cancer were analyzed using the average annual percent change (AAPC). Results: Totally 17 080 deaths were reported due to gastric cancer in Wenzhou City from 2014 to 2023, accounting for 12.58% and ranking third in the order of malignant tumor deaths. The crude mortality of gastric cancer was 20.73/105, and the standardized mortality was 15.22/105, showing decreasing trends (AAPC=-3.311%, -6.470%, both P<0.05). The crude mortality of gastric cancer was 29.22/105 in men and 11.61/105 in women, with standardized mortality rates of 20.81/105 and 8.74/105 (both P<0.05). The crude mortality of gastric cancer appeared a tendency towards a rise with increasing age (P<0.05), reaching the highest rate of 225.88/105 in the group aged 80 to <85 years. The PYLL and PYLLR of gastric cancer were 107 607.50 person-years and 1.37‰. The PYLLR appeared a tendency towards a decline from 2014 to 2023, with AAPC of -6.667% (P<0.05). Conclusions The mortality and PYLLR of gastric cancer in Wenzhou City appeared a tendency towards a decline from 2014 to 2023. Men and the elderly populations were the key groups for the prevention and treatment of gastric cancer.

OBJECTIVE To summarize the current situation of pharmaceutical clinic service in our hospital over the past five years， and explore sustainable development strategies for service models of pharmaceutical clinics. METHODS A retrospective analysis was conducted on the consultation records of patients who registered and established files at the pharmaceutical clinic in our hospital from January 2019 to December 2023. Statistical analysis was performed on patients’ general information， medication- related problems， and types of pharmaceutical services provided by pharmacists. RESULTS A total of 963 consultation records were included， among which females aged 20-39 years accounted for the highest proportion （66.04%）； obstetrics and gynecology- related consultations accounted for the largest number of cases. Additionally， 80 patients attended follow-up visits at our hospital’s pharmaceutical clinic. A total of 1 029 medication-related issues were resolved， including 538 cases of drug consultations （52.28%）， 453 medication recommendations （44.02%）， 22 medication restructuring（2.14%）， and 16 medication education （1.55%）； the most common types of medication-related problems identified were adverse drug events（70.07%）. CONCLUSIONS Although the pharmaceutical clinic has achieved recognition from clinicians and patients， challenges such as low awareness among healthcare providers and the public persist. Future efforts should focus on strengthening information technology construction， enhancing pharmacist training， and establishing various forms of outpatient pharmaceutical service models.

Background During pregnancy, negative emotions such as anxiety and depression may induce cortisol disruption. Cortisol can be transmitted to the fetus through the placental barrier, thereby affecting the neurodevelopment of the offspring. Objective To investigate the relationship between placental cortisol, maternal depression during pregnancy, and neurodevelopment of 3-month-old infants. Methods From September 2022 to September 2023, 171 pregnant women ordered routine prenatal checks at the obstetrics outpatient department of a tertiary hospital in Ningxia were selected using a prospective cohort design. After providing informed consent, these women participated in a questionnaire survey that covered general individual characteristics, prenatal depression, and sleep quality. At birth, placental samples were collected to measure cortisol levels using ELISA kits. Follow-up assessments on the neurodevelopmental of 3-month-old infants were conducted using the Warning Sign for Children Mental and Behavioral Development. LASSO regression analysis was conducted to screen the influencing factors of depression during pregnancy. Huber regression analysis was then applied to assess potential linear relationship between depression during pregnancy and placental cortisol levels. Log-binomial regression was used to analyze the linear relationships between cortisol levels and neurodevelopmental delay in 3-month-old infants. Additionally, a mediation effect model was fitted using R 4.3.3 to assess possible mediating role of cortisol in the association between prenatal depression and neurodevelopmental delay in 3-month-old infants. Results The positive rate of prenatal depression was 33.33%. Nine factors affecting prenatal depression were identified by LASSO regression, including rural residence, high school education or above, extroverted personality characteristics, moderate early pregnancy reactions, baby sex expectation, prenatal anxiety, family dysfunction, exposure to stressful life events during pregnancy, and moderate prenatal sleep quality. The Huber regression model showed a positive linear correlation between prenatal depression and placental cortisol (P<0.05). With or without controlling confounding factors, the results of log-binomial regression modeling showed that cortisol levels were associated with a reduced risk of neurodevelopmental delay in 3-month-old infants (crude model: RR=0.988, 95%CI: 0.9768, 0.9996, P＜0.05; adjusted model: RR=0.988, 95%CI: 0.9764, 0.9993, P＜0.05). A mediating effect of placental cortisol between prenatal depression and the risk of neurodevelopmental delay in 3-month-old offspring was found statistically significant (P=0.045), accounting for 67.0% of the total effect. Conclusion Prenatal depression is associated with elevated placental cortisol levels, and higher cortisol levels are found to be related to a lower risk of neurodevelopmental delay in infants. Placental cortisol mediates the relationship between prenatal depression and infant neurodevelopment.

ObjectiveTo compare the contents and relative molecular weight distributions of proteins and polypeptides in Naoxuekang dropping pills， Huoxue Tongmai capsules and Maixuekang capsules of Hirudo single medicinal preparations， to evaluate the in vitro anticoagulant， antiplatelet and fibrinolytic activities of the three preparations， and to investigate the effects of temperature， pH and digestive enzymes on the anticoagulant activities of the three preparations. MethodsThe contents of soluble proteins and polypeptides in the three preparations were determined by bicinchoninic acid assay（BCA） and Bradford method， and the relative molecular weight distributions of the three preparations were determined by electrophoresis combined with gel chromatography. The antithrombin activity of the three preparations was evaluated by fibrinogen-thrombin time（Fibg-TT） method， and their anticoagulant activities were further assessed by the elongations of activated partial thromboplastin time（APTT）， prothrombin time（PT） and thrombin time（TT）. The antiplatelet aggregation activities of the three preparations were measured by turbidimetry and the fibrinolytic activities were measured by fibrin plate method. Relative TT was used as index to investigate the effects of temperature， pH and digestive enzyme buffer on anticoagulant activities of the three preparations. ResultsAt the lowest single dosage， the contents of proteins and polypeptides were in the order of Maixuekang capsules>Huoxue Tongmai capsules>Naoxuekang dropping pills. Both Huoxue Tongmai capsules and Maixuekang capsules had 11 electrophoretic bands between 4.0 kDa and 90 kDa， the bands of Maixuekang capsules were more clear in the range of >25 kDa， and there was 1 obvious band at 14 kDa for the two capsules. Huoxue Tongmai capsules had one specific band at 9.0 kDa and Maixuekang capsules had one specific band at 48.0 kDa. Naoxuekang dropping pills only had 2 electrophoretic bands at 6.5 kDa and 8.5 kDa， primarily containing peptides below 2 kDa， most of which were oligopeptides. The anticoagulant activity concentrations of the three preparations exhibited a certain dose-dependent effect. At the lowest single dosage， The anticoagulant activity concentrations were ranked as Naoxuekang dropping pills>Huoxue Tongmai capsules>Maixuekang capsules. The prolongation effect of the three preparations on coagulation time was dose-dependent. At the same concentration， the prolongation effect of Naoxuekang dropping pills and Huoxue Tongmai capsules was APTT prolongation rate>TT prolongation rate>PT prolongation rate， whereas for Maixuekang capsules， the sequence was TT prolongation rate>APTT prolongation rate>PT lengthening rate. At the single minimum dosage， the order of APTT prolongation rate was Maixuekang capsules>Huoxue Tongmai capsules≈Naoxuekang dropping pills， the order of PT prolongation rate was Naoxuekang dropping pills≈Maixuekang capsules>Huoxue Tongmai capsules， and the order of TT prolongation rate was Maixuekang capsules>Huoxue Tongmai capsules>Naoxuekang dropping pills. The three preparations showed dose-dependent effects on platelet aggregation induced by adenosine diphosphate（ADP） and arachidonic acid（AA）， and the effect induced by ADP was stronger than that induced by AA. The anti-platelet aggregation effect of Naoxuekang dropping pills was significantly stronger than that of Maixuekang capsules（P<0.01）， whereas Huoxue Tongmai capsules had the effect of promoting platelet aggregation. None of the three preparations had the ability to dissolve fibrin. The anticoagulant activity of Naoxuekang dropping pills was least affected by heating， while the activities of the two capsules decreased significantly within 5 min above 80 ℃， and continued to decrease within 2 h. Compared with pure water， the anticoagulant activities of the three preparations could be increased by 1-3 times under strong acidity（pH 1-3）. In the pepsin buffer， the anticoagulant activity of Naoxuekang dropping pills could be increased by 1-3 times， while the anticoagulant activities of Huoxue Tongmai capsules and Maxuekang capsules were significantly decreased， the lowest levels were about 60% and 20%， respectively. In trypsin buffer， the anticoagulant activities of Naoxuekang dropping pills， Huoxue Tongmai capsules and Maixuekang capsules decreased significantly， and the lowest levels decreased to about 41%， 41% and 35%， respectively. ConclusionThe contents of proteins and polypeptides and relative molecular weights of the preparations derived from lyophilized fresh Hirudo powder， dried Hirudo powder and reflux extract of Hirudo decrease sequentially， and the anticoagulant activity decrease gradually， but the anticoagulant pathway is different. And the anti-platelet aggregation activity of the reflux extract is significantly enhanced. The heat resistance and gastrointestinal stability of the three preparations increase successively， and the first two are suitable for enteric-soluble preparations， while the latter is suitable for routine oral administration. The above results can provide data reference for the rationality of different preparation methods， active substances， pharmacodynamics and mechanism of Hirudo preparations.
