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.

OBJECTIVE To investigate the effects of borneol on pharmacodynamic and pharmacokinetic effects of Corydalis saxicola total alkaloids in depression model rats. METHODS Thirty male SD rats were divided into blank control group, negative control group, positive control group (fluoxetine 10 mg/kg, i.g.), single drug group (C. saxicola total alkaloids 210 mg/kg, i.g.) and combined drug group (C. saxicola total alkaloids 210 mg/kg+borneol 50 mg/kg, i.g.) according to the random number table method, with 6 rats in each group. By lipopolysaccharide (LPS) induction modeling, except blank control group (no model and no administration) received intraperitoneal injection of the same amount of normal saline, the rats in the other groups were intraperitoneally injected with LPS once a day to establish a rat model of depression. After 1 week of modeling, each administration group was given relevant drug intragastrically according to the corresponding dose, and blank control group and negative control group (without drug treatment) were administered intragastrically with an equal volume of solvent to dissolve the drug; continued modeling while administering the drug. After two weeks of continuous administration, the effects of C. saxicola total alkaloids versus the combination of C. saxicola total alkaloids and borneol on the behavior of depressed rats were tested by behavioral experiments; the levels of tumor necrosis factor-α, interleukin-1β and interleukin-6 in rats were determined; the histopathological changes of the hippocampus of rats were observed. Blood sample was collected from the orbit at different time points after administration on the 15th day, and the upper plasma was obtained. Ultra-performance liquid chromatography-triple quadrupole tandem mass spectrometry was established for the simultaneous determination of dehydrocarvedine, tetrahydropalmatine, coptisine, palmatine, jatrorrhizine, berberine, berberrubine and epiberberine in rat plasma. The average plasma concentration-time curve was depicted, the area under the curve (AUC) was calculated, and the pharmacokinetic parameters were analyzed by DAS 3.2.2 software. RESULTS Compared with blank control group, the negative control group had a decrease in body mass and sugar water preference rate, a decrease in the total distance of open field, a prolonged swimming immobility time, and a increased in the expression of inflammatory factors in serum (P<0.05); compared with negative control group, the single drug group and the combined drug group increased the preference rate of sugar water, increased the total distance of open field, shortened the time of swimming immobility, and decreased the expression of inflammatory factors in serum (P<0.05). There was no significant difference in the above indicators between the single drug group and the combined drug group in rats (P>0.05). Pharmacokinetic results showed that compared with single drug group, AUC0-t of coptisine, AUC0-t, AUC0-∞, tmax and cmax of jatrorrhizine, AUC0-t, AUC0-∞, t1/2 and cmax of berberrubine, and AUC0-t of epiberberine, cmax of dehydrocarvedine, cmax of palmatine were significantly increased in combined drug group, but there was no significant difference, indicating that borneol didn’t have a significant effect on the efficacy of Corydalis saxicola nigra at this dose. CONCLUSIONS Both C. saxicola total alkaloids alone and in combination with borneol can improve depression-like behavior in depression model rats, reduce serum inflammatory cytokine levels, and protect hippocampal neurons. Compared with the use of Corydalis saxicola base alone, the combination with borneol do not show significant pharmacodynamic differences, bu can improve the absorption of coptisine, jatrorrhizine in model rats.

Objective:
To investigate the urban and rural differences in adverse outcomes of pulmonary tuberculosis (PTB) in patients with pulmonary tuberculosis-diabetes mellitus comorbidity (PTB-DM), so as to provide insights into improving the prevention and treatment measures for PTB-DM.
Methods:
Patients with PTB-DM who were admitted and discharged from 14 designated tuberculosis hospitals in Hangzhou City from 2018 to 2022 were selected. Basic information, and history of diagnosis and treatment were collected through hospital information systems. The adverse outcomes of PTB were defined as endpoints, and the proportions of adverse outcomes of PTB in urban and rural patients with PTB-DM were analyzed. Factors affecting the adverse outcomes of PTB were identified using a multivariable Cox proportional hazards regression model.
Results:
A total of 823 patients with PTB-DM were enrolled, including 354 (43.01%) urban and 469 (56.99%) rural patients. There were 112 (13.61%) patients with adverse outcomes of PTB. The proportions of adverse outcomes of PTB in urban and rural patients were 14.41% and 13.01%, respectively, with no statistically significant difference (P>0.05). Multivariable Cox proportional hazards regression analysis identified first diagnosed in county-level hospitals or above (HR=2.107, 95%CI: 1.181-3.758) and drug resistance (HR=3.303, 95%CI: 1.653-6.600) as the risk factors for adverse outcomes of PTB in urban patients with PTB-DM, while the treatment/observed management throughout the process (HR=0.470, 95%CI: 0.274-0.803) and fixed-dose combinations throughout the process (HR=0.331, 95%CI: 0.151-0.729) as the protective factors for adverse outcomes in rural patients with PTB-DM.
Conclusions
There are differences in influencing factors for adverse outcomes of PTB in urban and rural patients with PTB-DM. The adverse outcomes of PTB are associated with first diagnosed hospitals and drug resistance in urban patients, and are associated with the treatment/observed management and fixed-dose combinations throughout the process in rural patients.

As a new type of model organism, zebrafish is gradually gaining prominence in the field of scientific research. The unique biological characteristics and advantages of zebrafish make them play an increasingly important role in the quality evaluation of traditional Chinese medicine. Compared with other common experimental animals, zebrafish have a fast reproductive and growth speed and high embryo transparency, making them an ideal model for evaluating the quality of traditional Chinese medicine. This provides a new perspective and method for research on traditional Chinese medicine. With the growing global interest in traditional Chinese medicine, it has become crucial to find scientific and accurate methods to evaluate the quality and effectiveness of traditional Chinese medicine. The introduction of the zebrafish model has brought new breakthroughs in the quality evaluation of traditional Chinese medicine. To further promote the application of zebrafish in evaluating the quality of traditional Chinese medicine, this article systematically searched and sorted out the previous studies related to the application of zebrafish for this purpose since 2023. The commonly used disease models and indicators of zebrafish in evaluating the effectiveness of traditional Chinese medicine, as well as the mechanism of zebrafish in exploring the active ingredients of traditional Chinese medicine, were primarily reviewed. The application of zebrafish in evaluating the safety of traditional Chinese medicine and the typical examples in ensuring the quality of traditional Chinese medicine were demonstrated. The limitations encountered by zebrafish models in evaluating the quality of traditional Chinese medicine were highlighted. The resolution of these problems will help further improve the accuracy and reliability of zebrafish in evaluating the quality of traditional Chinese medicine. The article discussed the evaluation of effectiveness, safety, and quality control of zebrafish applied in traditional Chinese medicine, so as to provide a reference for establishing standards for traditional Chinese medicine and promoting its modernization in the future.

ObjectiveTo investigate the association and translational mechanism between the hepatotoxicity of Xianling Gubao (XLGB) and its treatment of osteoporosis based on a zebrafish model. MethodsZebrafish were randomly selected four days after fertilization (4 dpf) and exposed to different concentrations of XLGB (0.7,0.35 mg·L-1) for 96 h. At the endpoint of the exposure, the mortality rates of zebrafish in the treatment groups of different concentrations were counted, and the "dose-toxicity" curves were plotted. The 10% sublethal concentration (LC10) was calculated. The liver area, acridine orange staining, and pathological tissue sections of transgenic zebrafish [CZ16 (gz15Tg.Tg (fabp 10a: ds Red; ela31: EGFP)] were used as indicators to confirm the hepatic damage caused by the sublethal concentration of XLGB. By using the prednisolone (PNSL)-induced osteoporosis model of zebrafish, the anti-osteoporosis activity of XLGB was evaluated by using the area of skull stained by alizarin red and the cumulative optical density value as indicators. Then, the toxicity difference of XLGB on the liver of zebrafish in healthy and osteoporotic states was compared, and the mechanism of the translational action of the toxicity of XLGB was predicted based on network pharmacology and real-time polymerase chain reaction(Real-time PCR). ResultsThe LC10 of XLGB on zebrafish (8 dpf) was 0.7 mg·L-1. Compared with the blank group, the sublethal concentration (LC10=0.7 mg·L-1, 1/2 LC10=0.35 mg·L-1) of XLGB induced an increase in the number of apoptosis of hepatocytes in a dose-dependent manner, and the tissue arrangement of the liver was disordered and loose. The vacuoles were obvious, and the fluorescence area of the liver was significantly reduced (P<0.01). Compared with the blank group, the mineralized area and cumulative optical density value of zebrafish skull in the PNSL model group were significantly reduced (P<0.01), and those in the 0.7,0.35 mg·L-1 XLGB treatment group were significantly increased compared with the model group (P<0.01). Most importantly, 0.7 mg·L-1 XLGB had no significant effect on the liver of zebrafish in the osteoporosis disease model compared with the blank group. The results of network pharmacology and real-time PCR experiments showed that the toxic transformation of XLGB might be related to the differences in the expression levels of key targets, such as tumor protein 53 (TP53), cysteine aspartic acid specific protease-3(Caspase-3), interleukin(IL)-6, and alkaline phosphatase(ALP) in different organismal states. ConclusionUnder certain conditions, XLGB has hepatotoxicity in normal zebrafish, but under osteoporotic conditions, XLGB not only exerts significant anti-osteoporosis activity but also alleviates hepatotoxicity significantly, which provides a reference for the safe clinical use of XLGB and real evidence for the theories of traditional Chinese medicine of attacking poison with poison and of treating disease with corresponding drugs without damage to the body.

ObjectiveTo investigate the effect of folic acid-modified crebanine polyethylene glycol-polylactic acid hydroxyacetic acid copolymer(PEG-PLGA) nanoparticles(FA-Cre@PEG-PLGA NPs, hereinafter referred to as NPs) combined with ultrasonic irradiation on subcutaneous tumor of liver cancer in Kunming(KM) mice. MethodsEighty-four healthy male KM mice were utilized to establish a subcutaneous tumor model of mouse hepatocellular carcinoma with H22 cells, then mice were randomly divided into model group, placebo group, hydroxycamptothecin group(8 mg∙kg-1), low, medium and high dose crebanine raw material groups(2, 2.5, 3 mg∙kg-1, hereinafter referred to as the low, medium and high dose crebanine groups, respectively), low, medium and high dose NPs groups(2, 2.5, 3 mg∙kg-1), and low, medium and high dose NPs combined with ultrasonic irradiation groups(2, 2.5, 3 mg∙kg-1, hereinafter referred to as the low, medium and high dose combination groups, respectively). The corresponding doses of drugs were administered via tail vein injection, the model group received no treatment, while the placebo group was injected with an equivalent amount of normal saline. Dosing was conducted for a total of 10 times on alternate days. The body mass of the mice was monitored, and parameters such as body mass change rate, thymus index, spleen index, tumor volume, tumor weight, relative tumor growth rate(T/C), and tumor inhibition rate(TGI) were calculated. Pathological changes in liver and kidney tissues as well as the tumor were observed by hematoxylin-eosin(HE) staining. Additionally, the levels of aspartate aminotransferase(AST), alanine aminotransferase(ALT), blood urea nitrogen(BUN) and creatinine(CREA) in serum of mice were detected by biochemical method. Furthermore, the effect of ultrasound on the distribution of NPs in subcutaneous tumors of mouse hepatocellular carcinoma was observed by in vivo imaging technique. ResultsAmong different treatment methods, the combination of NPs and ultrasound irradiation had the best therapeutic effect. Compared with the model group, the body mass growth rates of mice in the medium and high combination groups decreased, while the thymus index and spleen index increased, but there was no statistically significant difference in serum AST, ALT, BUN and CREA levels, indicating that NPs combined with ultrasound irradiation had little effect on the normal physiological state of the body, oth groups had TGI>40% and T/C<60%, indicating a clear anti-tumor effect. Pathological analysis showed that compared with the NPs groups, the combination groups exhibited varying degrees of necrosis in tumor cells, accompanied by less damage to the liver and kidneys. In vivo imaging of small animals showed that compared with the high dose NPs group, the high dose combination group had stronger tumor targeting ability(P<0.01). ConclusionNPs combined with ultrasonic irradiation can not only effectively targeted the drug to the tumor site, inhibit the subcutaneous tumor growth of mouse liver cancer, but also decrease damage to liver and kidney tissues.

ObjectiveTo establish fingerprint profiles and a quantitative determination method for Lycii Cortex, providing a scientific basis for the formulation of quality standards for Lycii Cortex and its roasted products. MethodsHigh performance liquid chromatography(HPLC) was developed for the quantitative method for determining kukoamine B in Lycii Cortex and its roasted products on an Alphasil XD-C18 CH column(4.6 mm×250 mm, 5 μm). HPLC fingerprint profiles were established for 10 batches of Lycii Cortex and its roasted products, and ultra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry(UPLC-Q-TOF-MS) was used to identify the common peaks based on reference standards, literature and MS information. Quality evaluation indicators included yield of decoction pieces, appearance properties, content of kukoamine B, and fingerprint profiles. The temperature and time of the roasting process were investigated to select the optimal preparation process, which was then verified. Additionally, chemical pattern recognition was combined to assess the differences in the chemical composition of Lycii Cortex before and after roasting, as well as among samples from different origins. ResultsQuantitative analysis indicated that the contents of kukoamine B in Lycii Cortex and its roasted products were 0.35%-5.51% and 0.24%-4.15%, respectively. The transfer rate of kukoamine B was 58.6%-78.9% after roasting. The fingerprint profile analysis demonstrated that the method established in this study effectively separated kukoamine B from other components in the samples and distinctly differentiated it from its impurity peak, cis-N-caffeoylputrescine. The HPLC fingerprint profiles of Lycii Cortex and its roasted products showed high similarity(all above 0.95), with 7 common peaks identified and five common components, including kukoamine B, cis-N-caffeoylputrescine, N-coumaroyl tyramine, feruloyltyramine, and glucosyringic acid, confirmed. Process optimization confirmed that baking at 110 ℃ for 20 min was a stable and feasible method for roasting Lycii Cortex. Principal component analysis and cluster analysis showed that there was little difference in the chemical composition between raw and roasted Lycii Cortex, but the quality of Lycii Cortex from different origins differed greatly. ConclusionThis study successfully established the fingerprint profiles and a quantitative method for the effective component kukoamine B in Lycii Cortex and roasted Lycii Cortex. The qualitative and quantitative analyses clarified that the impact of the roasting process on the chemical composition of Lycii Cortex was less significant than the variations due to its geographical origin. The findings of this study offer a reference for the development of quality evaluation methods and the establishment of quality standards for Lycii Cortex and its processed products.

Depression is a common psychiatric disorder characterized by persistent low mood or mental disorders. Current treatments primarily focus on regulating neurotransmitter levels, but their effectiveness is limited. The mechanisms underlying its onset are complex, and there is no unified consensus. Abnormal signaling pathway transmission plays a crucial role in the development of depression, involving multiple pathways, including Toll-like receptor 4/nucleotide-binding oligomerization domain-like receptor protein 3 (TLR4/NLRP3), nuclear factor-κB (NF-κB), Janus kinase/signal transducer and activator of transcription (JAK/STAT), mitogen-activated protein kinase/extracellular signal-regulated kinase (MAPK/ERK), brain-derived neurotrophic factor/tyrosine kinase receptor B (BDNF/TrkB), cyclic AMP/protein kinase A/cAMP response element-binding protein (cAMP/PKA/CREB), and others. Traditional Chinese medicine(TCM) is based on a holistic approach and the principle of treatment based on the differentiation of syndromes, regulating the balance of multiple systems and organ functions from a macroscopic perspective. This approach has shown unique advantages in the treatment of depression. TCM attributes the onset of depression to dysfunction of the organ systems, involving liver Qi stagnation, heart spirit deficiency, kidney essence depletion, and spleen dysfunction. TCM compound treatments focus on soothing the liver, strengthening the spleen, calming the heart, and replenishing essence, with formulas such as Xiaoyaosan, Zishui Qinggan Yin, and Chahu Jia Guizhi Longgu Muli Tang. The active components of Chinese herbs mainly aim to tonify and regulate Qi, such as salidroside, ginsenoside Rb1, astragaloside, and muscone. External TCM treatments, primarily acupuncture, aim to open the orifices and invigorate the spirit. Acupoints such as Baihui, Shenting, and Yintang are commonly used. Additionally, massage and moxibustion therapy can intervene in depression by regulating signaling pathways. This article reviews the core role of signaling pathways in the development of depression and the mechanism of TCM regulation of signaling pathways to intervene in depression, aiming to discover new therapeutic approaches that can improve the symptoms of depressed patients.
