ObjectiveTo investigate the effects of Schisandrae Chinensis Fructus lignans on schizophrenia induced by dizocilpine maleate (MK-801) in mice and to clarify its mechanism. MethodsMale mice of 4-6 weeks old were randomized into blank, model, positive drug, and low-, medium-, and high-dose (40, 80, 160 mg·kg-1, respectively) Schisandrae Chinensis Fructus lignans groups. The blank group was administrated with distilled water, and the other groups were injected with 0.5 mg·kg-1 MK-801 to induce schizophrenia symptoms. Meanwhile, risperidone was injected at 0.2 mg·kg-1 in the positive drug group, and mice in the intervention groups were injected with corresponding drugs for 14 consecutive days. The behavioral changes of mice were observed by autonomous activity test, open field test, forced swimming test, and water maze test. The levels of dopamine (DA) and 5-hydroxytryptamine (5-HT) in the brain and tumor necrosis factor-α (TNF-α) and nuclear factor-κB (NF-κB) in peripheral blood were quantified by enzyme-linked immunosorbent assay (ELISA). The changes in the prefrontal lobe of mice were observed by hematoxylin-eosin staining, and the changes of the hippocampal tissue were observed by Nissl staining. The protein levels of silencing information regulatory factor 1 (SIRT1) and forkhead box protein O3a (FoxO3a) in the hippocampus of mice were determined by Western blot. ResultsCompared with the model group, low, medium, and high doses of Schisandrae Chinensis Fructus lignans reduced the total number of autonomous activities, total distance in the open field test, immobile time in the forced swimming test, and levels of TNF-α and NF-κB in peripheral blood (P<0.05), while increasing the number of platform crossings in the water maze test and DA and 5-HT levels in the brain tissue (P<0.05). Compared with the model group, risperidone and low, medium, and high doses of Schisandrae Chinensis Fructus lignans improve the neural cell morphology in the CA1 region, with full cells in neatly dense arrangement and exhibiting clear membrane boundary. Schisandrae Chinensis Fructus lignans inhibited the expression of SIRT 1 and FoxO3a in the hippocampus (P<0.05). ConclusionTo sum up, Schisandrae Chinensis Fructus lignans may improve the behavior of schizophrenic mice by activating the SIRT1/FoxO3a signaling pathway to exert neuroprotective effects.

ObjectiveTo establish a castrated male mouse model and to preliminarily investigate the effects of testosterone replacement therapy (TRT) on behavior, serum indices, and histopathological changes in castrated mice, as well as to explore the role of androgens in cognitive function. MethodsForty 6-month-old male C57/BL6J mice were randomly divided into sham operation group, castration group, testosterone propionate (0.5,1.0 mg/kg) treated group, with 10 mice in each group. Following castration and subcutaneous administration of testosterone propionate at different doses (0.5 and 1.0 mg/kg) for TRT, learning and memory abilities were assessed using the Morris water maze (MWM) test and the passive avoidance test. Serum testosterone and serum brain-derived neurotrophic factor (BDNF) levels were measured by ELISA, and histopathological changes in the hippocampus were examined using hematoxylin-eosin (HE) staining. ResultsRoutine observations: there were no statistically significant differences in body weight among groups at any time point. MWM test: compared with castration group, sham operation group and testosterone propionate-treated groups (0.5, 1.0 mg/kg) showed significantly reduced escape latency on days 4 and 5 (P0.05), while the number of platform crossings and the time spent in the target quadrant significantly increased (P0.05). Passive avoidance test: the number of passive avoidance errors significantly decreased in sham operation group and testosterone propionate (1.0 mg/kg)-treated group (P0.05), and the passive avoidance latency was significantly prolonged in sham-operated group and testosterone propionate-treated groups (0.5, 1.0 mg/kg) (P0.05). Serum testosterone and serum BDNF assays: serum testosterone levels and serum BDNF concentrations significantly increased in sham operation group and testosterone propionate-treated groups (0.5, 1.0 mg/kg) (P0.01). HE staining: compared with sham operation group, neuronal density in all hippocampal subregions was slightly reduced in castration group; in the testosterone propionate (0.5 mg/kg)-treated group, neuronal arrangement in the CA1 and CA3 regions was improved and apoptotic cells were reduced compared with castration group; in testosterone propionate (1.0 mg/kg)-treated group, the pyramidal cell layer in the CA3 region was more compactly arranged, with fewer apoptotic cells than in castration group. ConclusionTRT improves learning and memory performance in castration male mice, potentially through modulation of hippocampal BDNF signaling pathways.

Objective:To analyze the effects of entecavir on tear secretion and tear film function in patients with hepatitis B virus (HBV) infection.Methods:A retrospective analysis was conducted on the clinical data of 24 patients with HBV infection who received treatment with entecavir at the Department of Ophthalmology, Affiliated Hospital of Shaoxing University from April to October 2022. The relevant examination results of dry eye in these patients were analyzed before medication and at 1 and 3 months after medication.Results:Before medication, 13 cases (54.17%) had dry eye, and 3 months after medication, 17 cases (70.83%) had dry eye. At 1 and 3 months after treatment with entecavir, the Ocular Surface Disease Index values of the patients were (13.83 ± 7.11) points and (15.29 ± 6.94) points, respectively. There was no significant difference in Ocular Surface Disease Index value between before and after treatment ( t = -0.24, -1.24, both P>0.05). At 1 and 3 months after treatment, the Schirmer I test results were (8.74 ± 2.40) mm and (8.21 ± 2.40) mm, respectively. The Schirmer I test results at 3 months after treatment were significantly lower than those before treatment ( t = 2.12, P<0.05). At 3 months after treatment, the tear film break-up time was reduced to (7.63 ± 1.97) seconds, which was significantly shorter than the value recorded before treatment ( t = 2.12, P<0.05). At 3 months after treatment, the height of the tear meniscus was (0.21 ± 0.06) mm, which was significantly different from that measured before treatment ( t = 2.26, P<0.05).At 3 months after treatment, the red eye index increased compared with the value recorded before treatment, but the difference was not statistically significant ( t = -0.35, -0.94, both P>0.05). Conclusions:Patients with HBV infection are prone to developing dry eye syndrome. After treatment with entecavir, there may be a reduction in tear secretion and a decline in tear film function, which should be a concern for clinicians.

Objective:To understand spatial aggregation of lung cancer mortality and its changing trends over the past fifty years in different counties and districts of Shandong Province from 1970 to 2021.Methods:The mortality data of lung cancer were obtained from the death registration system of Shandong province and three retrospective surveys of death cause. The mortality rate and age-standardized mortality rate were used to describe the changing trend of lung cancer in different years, and the contribution value of population factors and non-population factors in lung cancer mortality change was calculated by the mortality differential decomposition method. GeoDa 1.20 and ArcGIS 10.8 software were used for spatial autocorrelation analysis and visualization map display.Results:The crude mortality rate of lung cancer in Shandong Province showed a significant upward trend from 1970 to 2021, rising from 7.22 per 100 000 in 1970-1974 to 62.73 per 100 000 in 2020-2021, with an increase of 7.69 times. Meanwhile, the standardized mortality rate of lung cancer exhibited a trend of increasing first and then decreasing. The differential analysis of lung cancer mortality in different years revealed that changes in crude mortality rates were the result of the combined effects of demographic and non-demographic factors. The proportion of population factors (aging population) leading to an increase in lung cancer mortality rate rose from 2.12% in 1990-1992 to 40.20% in 2020-2021. From a spatial distribution perspective, there were significant regional differences in lung cancer mortality rates among counties (cities, districts) in Shandong Province across different eras. Compared to the period of 1970-1974, the lung cancer mortality rates in all counties and districts in 2020-2021 showed a considerable increase, and there were noticeable changes in the areas of high-high and low-low clustering of lung cancer mortality rates across different eras.Conclusion:There have been significant temporal and spatial changes in the mortality rate of lung cancer in Shandong Province from 1970 to 2021. The crude mortality rate has shown an upward trend, while the standardized mortality rate increases first and then decreases. The concentration of lung cancer mortality rates in counties and districts has also undergone significant changes.

Chronic prostatitis,a common condition in andrology,is clinically characterized by a prolonged course,resistance to treatment,and frequent recurrence.In traditional Chinese medicine,it is classified under the categories of"turbid sperm,""overstrain strangury,"and"vaginal pain."Based on the"host-guest interaction-collateral disease"theory,we believe that healthy qi deficiency,latent pathogenic factors,and collateral obstruction are the primary pathological factors of this disease,which run through the entire process of chronic prostatitis occurrence and development.Accordingly,we propose that obstruction of collaterals and apathesia of the semen chamber are the core pathogenesis.The disease progression can be divided into three pathological stages:"deficiency,depression,and blood stasis."Spleen and kidney deficiency and malnutrition of collaterals form the pathological foundation.In the deficiency stage,treatment strategies involve reinforcing qi and nourishing the collaterals,using Fuzheng Yangrong Decoction.During disease progression,dampness and heat invasion,as well as collateral stagnation qi,are key contributors to disease progression.Thus,treatment focuses on clearing heat and dampness,promoting qi flow,and smoothing the collaterals,achieved with a modified Qiantongding Decoction.In the final stage,blood stasis and collateral obstruction dominate,warranting therapeutic strategies aimed at tonifying and removing blood stasis,addressing both the body and the collaterals simultaneously using the modified Guiling Huayu Decoction.Overall,the clinical treatment generally focuses on the concept of function through free flow,combination of unblocking and tonifying.This study provides a novel perspective and reference for clinical differentiation and treatment of chronic prostatitis.
