ObjectiveTo explore the mechanism by which Xiaoyaosan regulates HPT axis dysfunction in the rat model with the syndrome of liver depression and spleen deficiency by observing its effect on the glycoprotein hormone α-subunit (CGA)/glutathione peroxidase 2 (GPX2)/thyroid-stimulating hormone β-subunit (TSHβ) pathway for thyroid hormone synthesis. MethodsSeventy-two male SD rats were randomized into six groups: normal, model, high-dose (16.7 g·kg-1), medium-dose (8.35 g·kg-1), and low-dose (4.175 g·kg-1) Xiaoyaosan, and fluoxetine (0.001 8 g·kg-1) groups, with 12 rats in each group. The rat model of liver depression and spleen deficiency was induced by chronic restraint stress for 21 days. The intervention groups were treated with Xiaoyaosan decoctions or fluoxetine suspension, respectively. After modeling, hematoxylin-eosin staining was employed to observe morphological changes in the thyroid and pituitary tissue of the rats. Serum levels of triiodothyronine (T3), tetraiodothyronine (T4), and thyroid-stimulating hormone (TSH) were measured by enzyme-linked immunosorbent assay (ELISA). Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) and Western blot were employed to determine the mRNA and protein levels, respectively, of TSH receptor (TSHR) in the thyroid tissue, thyrotropin-releasing hormone receptor (TRHR) and TSHβ in the pituitary tissue, and thyrotropin-releasing hormone (TRH), CGA, GPX2, and TSHβ in the hypothalamic tissue. ResultsCompared with the normal group, the model group showed significant atrophy and irregularity of thyroid follicles, a marked reduction in colloid secretion, extensive vacuolar degeneration of adenocytes in the anterior pituitary, lowered serum levels of T3, T4, and TSH (P<0.01), and down-regulated mRNA and protein levels of TSHR in the thyroid tissue, TRHR and TSHβ in the pituitary tissue, and TRH, CGA, GPX2, and TSHβ in the hypothalamic tissue (P<0.01). Compared with the model group, high- and medium-dose Xiaoyaosan and fluoxetine alleviated the pathological changes in the thyroid and pituitary tissue, outperforming the low-dose Xiaoyaosan group. Moreover, they elevated the serum levels of T3, T4, and TSH (P<0.05, P<0.01). The serum TSH level was also elevated in the low-dose Xiaoyaosan group (P<0.05). The mRNA and protein levels of TSHR in the thyroid, TRHR and TSHβ in the pituitary, and TRH, CGA, GPX2, and TSHβ in the hypothalamus were up-regulated in the high- and medium-dose Xiaoyaosan groups (P<0.05, P<0.01). Additionally, the mRNA and protein levels of TSHβ in the hypothalamus were up-regulated in the low-dose Xiaoyaosan group (P<0.01). In the fluoxetine group, the mRNA and protein levels of TSHR in the thyroid, TRHR in the pituitary, and TRH, CGA, and GPX2 in the hypothalamus were up-regulated (P<0.05, P<0.01). ConclusionThe downregulation of CGA/GPX2/TSHβ pathway may be one of the biological mechanisms underlying HPT axis dysfunction in the rat model with the syndrome of liver depression and spleen deficiency. Xiaoyaosan may regulate the HPT axis dysfunction by up-regulating the CGA/GPX2/TSHβ pathway.

ObjectiveTo explore the effect of serum containing Zhenwutang on myocardial mast cell apoptosis induced by angiotensin Ⅱ (AngⅡ) and the mechanism of the correlation between apoptosis and mitochondrial autophagy. MethodsIn this experiment, AngⅡ and serum containing Zhenwutang with different concentrations were used to interfere with H9C2 cardiomyocytes for 24 h, and the survival rate of H9C2 cardiomyocytes was detected by cell counting kit-8 (CCK-8) to screen the optimal concentration for the experiment. Enzyme-linked immunosorbent assay (ELISA) was used to detect the content of B-type natriuretic peptide (BNP) in cell culture supernatant, and immunofluorescence was used to detect the cell surface area to verify the construction of the myocardial mast cell model. Subsequently, the experiment was divided into a blank group (20% blank serum), a model group (20% blank serum + 5×10-5 mol·L-1 AngⅡ), low-, medium-, and high-dose (5%, 10% and 20%) serum containing Zhenwutang groups, an autophagy inhibitor group (1×10-4 mol·L-1 3-MA), and autophagy inducer group (1×10-7 mol·L-1 rapamycin). The apoptosis level of H9C2 cells and the changes of mitochondrial membrane potential were detected by flow cytometry. The lysosomal probe (Lyso Tracker) and mitochondrial probe (Mito Tracker) co-localization was employed to detect autophagy. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was used to detect Caspase-3, Caspase-9, B-cell lymphoma 2 (Bcl-2), Bcl-2-related X protein (Bax), and cytochrome C (Cyt C) in apoptosis-related pathways and the relative mRNA expression of ubiquitin ligase (Parkin), phosphatase and tensin homolog (PTEN)-induced kinase 1 (PINK1), and p62 protein in mitochondrial autophagy-related pathways. Western blot was used to detect cleaved Caspase-3, cleaved Caspase-9, Bax, Bcl-2, and Cyt C in apoptosis-related pathways, phosphorylated ubiquitin ligase (p-Parkin), phosphorylated PTEN-induced kinase 1 (p-PINK1), p62, and Bcl-2 homology domain protein Beclin1 in mitochondrial autophagy-related pathways, and the change of microtubule-associated protein 1 light chain 3 (LC3) Ⅱ/Ⅰ ratio. ResultsCCK-8 showed that when the concentration of AngⅡ was 5×10-5 mol·L-1, the cell activity was the lowest, and there was no cytotoxicity. At this concentration, the surface area of cardiomyocytes was significantly increased (P<0.01), and the content of BNP in the supernatant of culture medium was significantly increased (P<0.05). Therefore, AngⅡ with a concentration of 5×10-5 mol·L-1 was selected for the subsequent modeling of myocardial mast cells. Compared with the blank group, the model group and the autophagy inhibitor 3-MA group had a significantly increased apoptosis rate (P<0.01) and significantly decreased mitochondrial membrane potential (P<0.01). The results of immunofluorescence co-localization showed that compared with the blank group, the model group had a significantly decreased number of red and green fluorescence spots. The results of Real-time PCR showed that compared with that in the blank group, the relative mRNA expression of Bax, Caspase-3, Caspase-9, Cyt C, and p62 in the model group was significantly up-regulated (P<0.01), while the relative mRNA expression of Bcl-2, Parkin, and PINK1 was significantly down-regulated (P<0.01). In addition, the relative protein expression of Bax, cleaved Caspase-3, cleaved Caspase-9, Cyt C, and p62 was significantly up-regulated (P<0.01). The LC3Ⅱ/Ⅰ was significantly decreased, and the relative protein expression of Bcl-2, p-Parkin, p-PINK1, and Beclin1 was significantly down-regulated (P<0.01). Compared with the model group, the serum containing Zhenwutang groups and the autophagy inducer group had significantly decreased apoptosis rate (P<0.01), and the decrease ratio of mitochondrial membrane potential is significantly lowered (P<0.01) in a dose-dependent manner. Additionally, both red and green fluorescence spots became more in these groups. In the 3-MA group, the number of red and green fluorescence spots decreased significantly. The relative mRNA expression of Bax, Caspase-3, Caspase-9, Cyt C, and p62 was significantly down-regulated (P<0.05, P<0.01), while that of Bcl-2, Parkin, and PINK1 was significantly up-regulated (P<0.01). In the serum containing Zhenwutang groups, the relative protein expression levels of Bax, cleaved Caspase-3, cleaved Caspase-9, Cyt C, and p62 were significantly down-regulated (P<0.05,P<0.01). The LC3Ⅱ/Ⅰ was significantly increased, and the relative protein expression levels of Bcl-2, p-Parkin, p-PINK1, and Beclin1 were significantly up-regulated (P<0.01). ConclusionThe serum containing Zhenwutang can reduce the apoptosis of myocardial mast cells and increase mitochondrial autophagy. This is related to the inhibition of intracellular Bax/Bcl-2/Caspase-3 apoptosis pathway and regulation of Parkin/PINK1 mitochondrial autophagy pathway.

ObjectiveTo investigate the effect and mechanism of polysaccharide in water extract of Cyclocarya paliurus (CPWP) in inhibiting benign prostatic hyperplasia (BPH). MethodsCPWP was obtained by heating reflux, aqueous extraction, alcohol precipitation, and freeze drying. The chemical composition and structural properties of CPWP were analyzed by high performance liquid chromatography with 1-pheny-3-methyl-5-pyrazolone pre-column derivatization and infrared spectroscopy. Male SD rats were randomly assigned into control, model, finasteride (ig 5 mg·kg-1), and low-, medium-, and high-dose (ig 50, 75, 100 mg·kg-1) CPWP groups, with 8 rats in each group. The BPH model was established by subcutaneously injecting propionate testosterone in castrated rats. The rats in the drug intervention groups were administrated with corresponding drugs, and those in the control group were administrated with an equal volume of normal saline each day. After 30 consecutive days, the rats were sacrificed, and the prostate tissue was separated and weighed. The effects of drug interventions on the body weight, prostate wet weight, and prostate index of rats were examined. The prostate tissue was stained with hematoxylin-eosin (HE) for observation of pathological changes. Enzyme-linked immunosorbent assay was employed to measure the level of dihydrotestosterone (DHT), and immunohistochemical staining was used to detect the expression of steroid 5 alpha-reductase 2 (SRD5A2) and Ki67 in the prostate tissue. ResultsCPWP was identified as a saccharide, with characteristic absorption peaks of saccharides. CPWP showed the total sugar content of 44.15% and molecular weight within the range of 5.5-78.8 kDa, being composed of mannose, rhamnose, galacturonic acid, glucose, galactose, xylose, and arabinose. Compared with the control group, the model group had significantly increased prostate wet weight and prostate index (P<0.01), thick and tall prostate epithelial cells, increased internal wrinkles, papillary expansion into the cavity, an elevation in DHT level in the serum, and up-regulated expression of SRD5A2 and Ki67 in the prostate tissue (P<0.05, P<0.01). Compared with the model group, both the finasteride and CPWP groups showed decreases in prostate wet weight and prostate index (P<0.05, P<0.01), thinned prostate epithelial cells, with only a small portion of internal wrinkles and papillary expansion into the cavity, shortened papillary protrusions, lowered DHT level in the serum, and down-regulated expression of SRD5A2 and Ki67 in the prostate tissue (P<0.01). Moreover, CPWP exerted effects in a dose-dependent manner. ConclusionCPWP inhibits BPH by regulating the expression of SRD5A2.

ObjectiveTo investigate the mechanism of topical treatment of allergic contact dermatitis (ACD) mice with Portulacae Herba based on the nuclear factor E2-related factor 2 (Nrf2)/heme oxygenase-1 (HO-1)/nuclear factor-κB (NF-κB) signaling pathway. MethodsA total of 70 6-week-old specific pathogen free (SPF) female Kunming mice were adaptively fed for 1 week and randomly divided into blank group, model group, compound dexamethasone acetate cream group (2.075×10-2 g·g-1), blank matrix cream group, low-dose Portulacae Herba cream group (0.1 g·g-1), high-dose Portulacae Herba cream group (0.2 g·g-1), and Portulacae Herba + inhibitor group (0.2 g·g-1 + 30 mg·kg-1 ML385), with 10 mice in each group. One day before the experiment, the mice were shaved on the neck and back. Except for the blank group, the mice in the other groups were treated with 2,4-dinitrochlorobenzene (DNCB) to establish an ACD model. After respective administration, the skin lesion of the mice was scored, and the histopathological changes of the skin were stained with hematoxylin-eosin (HE). Enzyme-linked immunosorbent assay (ELISA) was used to detect the levels of interleukin-6 (IL-6), interleukin-1β (IL-1β), reactive oxygen species (ROS), superoxide dismutase (SOD) activity, and malondialdehyde (MDA) in serum of mice. The expression of Nrf2/HO-1/NF-κB signaling pathway-related proteins in mouse skin tissue was detected by immunohistochemistry (IHC), Western blot, and real-time fluorescence quantitative polymerase chain reaction (Real-time PCR). ResultsCompared with the blank group, the mice in the model group had an increased skin lesion score (P<0.01), severe pathological damage to skin tissue, increased content of IL-1β, IL-6, ROS, and MDA in their serum (P<0.01), and decreased content of SOD (P<0.01). In addition, the mRNA and protein expression levels of Nrf2, HO-1, and nuclear factor-κB inhibitor α (IκBα) in skin tissue were up-regulated (P<0.01), while the protein expression levels of phosphorylated (p)-IκBα and p-NF-κB p65 and the mRNA expression of NF-κB p65 were down-regulated (P<0.01). Compared with the model group and the blank matrix cream group, the mice treated with Portulacae Herba had a decreased skin lesion score (P<0.01), reduced pathological damage to skin tissue, decreased content of IL-1β, IL-6, ROS, and MDA in their serum (P<0.01), and increased content of SOD (P<0.01). Additionally, the mRNA and protein expression levels of Nrf2, HO-1, and IκBα in skin tissue were down-regulated (P<0.05,P<0.01), and the protein expression levels of p-IκBα and p-NF-κB p65 and the mRNA expression of NF-κB p65 were up-regulated (P<0.05,P<0.01). Compared with the Portulacae Herba + inhibitor group, the high-dose Portulacae Herba cream group had a decreased skin lesion score (P<0.01), alleviated pathological damage to skin tissue, decreased content of IL-1β, IL-6, ROS, and MDA in the serum of mice (P<0.05,P<0.01), and increased content of SOD (P<0.01). The protein expression levels of Nrf2, HO-1, and IκBα and the mRNA expression of Nrf2 and HO-1 in skin tissue were up-regulated (P<0.05,P<0.01), and the protein expression levels of p-IκBα and p-NF-κB p65 and the mRNA expression of NF-κB p65 were down-regulated (P<0.05). ConclusionPortulacae Herba can improve DNCB-induced ACD skin damage in mice by regulating the Nrf2/HO-1/NF-κB signaling pathway.

By consulting relevant literature of ancient herbal books and processing specifications, this paper made a systematic research and analysis of Ostreae Concha, including the name, producing area, harvesting, quality, historical evolution of processing, relevant processing specifications, modern processing technology, and changes in chemical composition and pharmacological effects before and after processing, in order to provide documentary evidence for the research on processing technology and the establishment of quality standards. According to the textual research, it is known that Ostreae Concha has a long history of being used in medicine, and there have been many aliases and local names in each historical period. Shennong's Classic of the Materia Medica(Shennong Bencaojing) began to use Muli as the correct name, which has continued to use to today, and there were also aliases such as Muge, Zuogu Muli and Haoke. Ostreae Concha has a wide range of localities and irregular harvesting periods. The ancients believed that its left shell was of superior quality, but this has not been seen in modern. And there were many kinds of processing methods of Ostreae Concha, such as grinding, roasting, calcining, frying, simmering, quenching and so on, and the calcining was still in use. The different editions of Chinese Pharmacopoeia from 1963 to 2020 contain only calcined Ostreae Concha, and the local processing specifications mainly include three kinds of processed products(calcined products, salt-soaked products and vinegar-soaked products). Modern processing research mainly focuses on process optimization, changes in chemical composition and pharmacological effects, and the research methods are relatively single. Overall, there are currently issues such as inconsistent processing standards, unclear process parameters and imperfect quality standards, which are not conducive to the quality control and standardized clinical use of Ostreae Concha. Therefore, it is necessary to further investigate the pharmacological substance basis of Ostreae Concha and its processed products in order to elucidate the processing mechanism, standardize the processing technology and improve the quality standard.

ObjectiveTo explore the effect of modified Ditan Decoction (涤痰汤) on chronic intermittent hypoxia cognitive function and the potential function mechanism. MethodsTwenty-four Sprague-Dawley (SD) rats were randomly divided into a normal group, a model group, and a modified Ditan Decoction group, with eight rats in each group. Rats in the modified Ditan Decoction group were administered the decoction by gavage at 14.8 ml/(kg·d), while the normal group and the model group received the same dose of normal saline. Thirty minutes after daily gavage, the rats in all three groups were placed in an intermittent hypoxia chamber. The oxygen concentration for the model group and the modified Ditan Decoction group was adjusted daily for 8 hours using a computer program to establish the model, while the normal group was exposed to the same airflow rate of ambient air. The intervention was continued for 12 weeks to establish a chronic intermittent hypoxia rat model. The Y-maze test was used to evaluate spatial working memory in the rats. Resting-state functional magnetic resonance imaging (rs-fMRI) was performed to detect whole-brain regional homogeneity (ReHo) and seed-based functional connectivity (FC). Brain regions showing significant differences in rs-fMRI were selected for further analysis. Immunofluorescence was used to detect β-amyloid (Aβ) deposition and the number of ionized calcium-binding adapter molecule 1 (IBA1)-positive microglial cells. Immunohistochemistry was employed to assess the expression of synaptophysin (SYP), the excitatory synapse marker vesicular glutamate transporter 1 (Vglut1), and the inhibitory synapse marker vesicular γ-aminobutyric acid transporter (VGAT). ResultsCompared with the normal group, the model group showed a reduced spontaneous alternation rate in the Y-maze test. The smoothed Z-score standardized regional homogeneity (SzReHo) value in the left entorhinal cortex significantly increased, and the FC value from this seed point to the left basal forebrain significantly reduced. Additionally, the model group exhibited significantly higher Aβ fluorescence intensity and Iba1 positivity in the left entorhinal cortex, decreased expression of SYP, Vglut1, and VGAT, along with an increased Vglut1/VGAT ratio (P<0.05 or P<0.01). Compared to the model group, the modified Ditan Decoction group demonstrated an increased spontaneous alternation rate, a significantly reduced SzReHo value in the left entorhinal cortex, and a significantly increased FC value from this region to the left basal forebrain. Furthermore, this group showed significantly lower Aβ fluorescence intensity and Iba1 positivity in the left entorhinal cortex, increased levels of SYP, Vglut1, and VGAT, and a decreased Vglut1/VGAT ratio (P<0.05 or P<0.01). ConclusionModified Ditan Decoction can reconstruct the projection from the left basal forebrain to the entorhinal cortex in chronic intermittent hypoxia, thereby reducing Aβ aggregation and excessive microglial activation in the left entorhinal cortex. This process improves the excitation/inhibition imbalance caused by synaptic remodeling, ultimately enhancing cognitive function in rats of chronic intermittent hypoxia.

Methods:
Data of the incidence and mortality of prostate cancer in Ningbo City from 2011 to 2023 were collected through Ningbo Chronic Disease Collaborative Management System. The incidence and mortality of prostate cancer were calculated and standardized by the data from the sixth national population census in 2010 and the Segi's world standard population in 1960. The trends in incidence and mortality of prostate cancer were evaluated using average annual percent change (AAPC).
Results:
A total of 15 411 cases of prostate cancer were reported in Ningbo City from 2011 to 2023, and the crude incidence, Chinese-standardized incidence and world-standardized incidence were 39.62/105, 22.18/105 and 16.49/105, respectively, showing upward trends (AAPC=14.782%, 10.390% and 10.608%, all P<0.05). The Chinese-standardized incidence of prostate cancer was higher in urban areas than in rural areas, and both showed upward trends (25.14/105 vs. 19.44/105; AAPC=9.057% and 14.272%, both P<0.05). The crude incidence of prostate cancer in the groups aged 50-<60 years, 60-<70 years, 70-<80 years and ≥80 years showed upward trends (AAPC=11.657%, 14.031%, 10.734% and 5.300%, all P<0.05). A total of 3 739 deaths were reported, and the crude mortality, Chinese-standardized mortality and world-standardized mortality were 9.66/105, 5.23/105 and 3.71/105, respectively, showing upward trends (AAPC=8.458%, 3.620% and 3.602%, all P<0.05). The Chinese-standardized mortality of prostate cancer was higher in urban areas than in rural areas, and both showed upward trends (5.35/105 vs. 5.13/105; AAPC=3.183% and 3.962%, both P<0.05). The crude mortality of prostate cancer the groups ageds ≥80 years showed an upward trend (AAPC=7.482%, P<0.05).
Conclusions
From 2011 to 2023, the incidence and mortality of prostate cancer in Ningbo City showed upward trends. Special attention should be paid to urban residents, and prostate cancer screening should be strengthened among males aged 50 years and older.

Objective To analyze the characteristics of postoperative hospital-acquired infections and drug sensitivity in lung transplant recipients over the past 5 years in a single center. Methods A total of 724 lung transplant recipients at Wuxi People's Hospital from January 2019 to December 2023 were selected. Based on the principles of hospital-acquired infection diagnosis, a retrospective analysis was conducted on the hospital infection situation and infection sites of lung transplant recipients, and an analysis of the distribution of hospital-acquired infection pathogens and their antimicrobial susceptibility test status was performed. Results Among the 724 lung transplant recipients, 275 cases of hospital-acquired infection occurred, with an infection rate of 38.0%. The case-time infection rate decreased from 54.2% in 2019 to 22.8% in 2023, showing a downward trend year by year (Z=30.98, P<0.001). The main infection site was the lower respiratory tract, accounting for 73.6%. The pathogens were mainly Gram-negative bacteria, with the top four being Acinetobacter baumannii (37.1%), Pseudomonas aeruginosa (17.3%), Klebsiella pneumoniae (13.7%), and Stenotrophomonas maltophilia (13.4%), with imipenem resistance rates of 89%, 53%, 58% and 100%, respectively. Gram-positive bacteria were mainly Staphylococcus aureus (3.6%), with a methicillin resistance rate of 67%. Conclusions Over the past 5 years, the hospital-acquired infections in lung transplant recipients have shown a downward trend, mainly involving lower respiratory tract infections, with the main pathogens being Acinetobacter baumannii, Pseudomonas aeruginosa and Klebsiella pneumoniae, all of which have high resistance rates to imipenem.
