ObjectiveTo investigate the feasibility, safety, and efficacy of surgery-assisted transjugular intrahepatic portosystemic shunt (SA-TIPS) in the treatment of portal hypertension comorbid with complex portal vein thrombosis, including cavernous transformation of the portal vein (CTPV). MethodsAn analysis was performed for the data of 36 patients with portal hypertension and complex portal vein thrombosis who underwent SA-TIPS in Beijing Shijitan Hospital, Capital Medical University, from November 2023 to January 2025, including general status, technical data of the surgical process (surgical success rate, puncture times, time of operation, the number of stents used, and the length of shunt), perioperative complications, and surgical recovery. The change in portal pressure gradient (PPG) after shunt was compared, and the rate of reaching the standard for PPG reduction was calculated, as well as stent patency rate within 1 week after surgery. The paired samples t-test was used for comparison of continuous data between two groups. ResultsAmong the 36 patients, 34 (94.4%) underwent SA-TIPS successfully. The incidence rate of perioperative complications was 16.7% (6/36), including 3 cases of thoraco-abdominal hemorrhage, 2 cases of intraoperative arrhythmia, and 1 case of incision infection. There was a significant reduction in PPG after SA-TIPS (t=19.85, P<0.01), and the patients achieving a ≥50% reduction in PPG accounted for 76.5% (26/34). Imaging reexamination within 1 week showed a shunt patency rate of 100%. ConclusionSA-TIPS has a high technical success rate, a favorable safety profile, and good efficacy in the treatment of portal hypertension comorbid with complex portal vein thrombosis (including CTPV), and therefore, it holds promise for clinical application.

Abnormal activation of the Janus kinase/signal transducer and activator of transcription (JAK/STAT) signaling pathway is involved in the pathogenesis of diffuse large B-cell lymphoma (DLBCL). In recent years, inhibitors targeting JAK2 and STAT3 have emerged as promising therapeutic candidates in DLBCL. This review summarizes the efficacy and safety profiles of JAK2 inhibitors (e.g., ruxolitinib) and STAT3 inhibitors (direct small-molecule inhibitors, the antisense oligonucleotide, and proteolysis targeting chimeras, etc.) in preclinical models and clinical trials. Accumulating evidence indicates that JAK2 and STAT3 inhibitors exhibit antitumor activity and are generally well tolerated in a subset of DLBCL patients. Meanwhile, the development of novel drug delivery systems has significantly enhanced the stability, bioavailability, and targeting ability of the compounds. Furthermore, JAK2 and STAT3 inhibitors may exhibit synergistic effects when combined with other therapy strategies (such as combinations with B-cell receptor signaling pathway inhibitors, immunomodulators, or other targeted drugs). However, current clinical applications are still in their early stages. Future research should concentrate on precision treatment strategies based on the genetic subtyping of DLBCL, and further refine the delivery systems for inhibitors as well as combination drug regimens to improve clinical outcomes.

ObjectiveTo investigate the mechanisms of Runmu Dihuang decoction (RMDHD) in treating perimenopausal dry eye with liver-kidney Yin deficiency syndrome based on the silent information regulator 3 (SIRT3)/hypoxia-inducible factor-1α (HIF-1α)/nuclear factor-κB (NF-κB) signaling pathway. MethodsSixty female Sprague-Dawley rats were randomly divided into six groups (n=10 per group): Sham operation group, model group, sodium hyaluronate eye drop group, and low-, medium-, and high-dose RMDHD groups (5.625, 11.25, 22.50 g·kg-1). Except for the sham operation group, all rats underwent bilateral ovariectomy and were administered 0.1% benzalkonium chloride eye drops combined with long-term chronic irritation to establish a perimenopausal dry eye model with liver-kidney Yin deficiency syndrome. Drug administration began in the 11th week after modeling and continued for 21 days. General conditions, screen-grip test scores, tear secretion volume, tear film breakup time (TFBUT), and corneal fluorescein staining were recorded. Serum levels of reactive oxygen species (ROS), follicle-stimulating hormone (FSH), estradiol (E2), and progesterone (PROG) were measured by enzyme-linked immunosorbent assay (ELISA). Pathological changes in the lacrimal glands, corneas, and uteri were observed using hematoxylin-eosin (HE) staining. Protein expression levels of SIRT3, HIF-1α, phosphorylated NF-κB p65 (p-NF-κB p65), and total NF-κB p65 in the lacrimal glands were detected by Western blot. The expression of inflammatory cytokines interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) in the lacrimal glands was assessed by immunohistochemistry (IHC). ResultsAfter model establishment, no significant differences were observed among the groups except the sham operation group. Compared with the sham operation group, the other groups exhibited slowed movement, dull responses, increased irritability, reduced body weight, elevated rectal temperature, decreased screen-grip test scores, reduced tear secretion, and significantly shortened TFBUT (P<0.05). After treatment, compared with the model group, the sodium hyaluronate eye drop group and all RMDHD groups showed improved general conditions, significantly increased tear secretion (P<0.05), prolonged TFBUT (P<0.05), and elevated screen-grip test scores (P<0.05). Serum ROS and FSH levels were significantly decreased, while E2 and PROG levels were significantly increased (P<0.05). Pathological damage to the cornea, lacrimal glands, and uterus was ameliorated. In addition, protein expression levels of SIRT3 and HIF-1α in the lacrimal glands were significantly upregulated (P<0.05), whereas the expression of p-NF-κB p65, IL-1β, and TNF-α was significantly downregulated (P<0.05). ConclusionRMDHD increases tear secretion and TFBUT, improves lacrimal gland and corneal injury, and alleviates dry eye symptoms in a perimenopausal dry eye rat model with liver-kidney Yin deficiency syndrome. The underlying mechanism may be related to regulation of the SIRT3/HIF-1α/NF-κB signaling pathway, inhibition of oxidative stress and inflammatory responses, and reduction of ocular surface tissue damage.

Objective:
To evaluate the safety and efficacy of the retroauricular transmeatal approach in the treatment of condylar head and neck fractures, and to provide a reference for clinical practice.
Methods:
This study has been reviewed and approved by the institutional medical ethics committee and has obtained informed consent from the patients. A retrospective analysis was conducted on the clinical data of patients with condylar head and neck fractures treated via the retroauricular transmeatal approach between March and October 2024. Postoperative follow-up was performed for at least 3 months, including clinical and radiographical evaluations. The assessed parameters included facial nerve function, temporal region numbness, hematoma, infection, salivary fistula, mouth opening, malocclusion, mandibular movement function, temporomandibular joint (TMJ) pain and clicking, external auditory canal (EAC) stenosis, hearing function impairment, surgical scar concealment, postoperative reduction and fixation outcomes.
Results:
A total of 16 patients with condylar fractures were treated via the retroauricular transmeatal approach, including 10 unilateral and 6 bilateral cases. Specifically, 18 sides were condylar head fractures, and 4 sides were condylar neck fractures. All patients achieved a House-Brackmann Grade I, indicating normal facial nerve function postoperatively. On postoperative day 1, 3 sides experienced temporal numbness in the temporal region on the surgical side, with spontaneous resolution in all cases. All patients recovered after surgery without hematoma, infection, or salivary fistula. Limited mouth opening was improved (14 cases with restricted mouth opening preoperatively vs. 3 cases postoperatively). No malocclusion occurred in any patient. All patients achieved satisfactory recovery of postoperative mandibular movement function, manifested as restored range of motion without pain. No TMJ clicking was observed within 3 months after surgery. One keloid-prone patient developed progressive EAC stenosis (2 mm lumen constriction) accompanied by conductive hearing impairment, which recovered after dilation therapy. All patients were satisfied with the aesthetic outcomes. Radiographically parametric assessment demonstrated satisfactory fracture reduction and fixation; with no loosening of titanium plates or screws.
Conclusion
The retroauricular transmeatal approach effectively reduces the risk of facial nerve injury and salivary fistulas formation with providing concealed scarring and high patient satisfaction. However, caution should be exercised regarding EAC stenosis, especially for keloid-prone patients.

ObjectiveTo analyze the processing mechanism underlying the enhanced effect of invigorating spleen and stopping diarrhea of soil-fried Atractylodis Macrocephalae Rhizoma(AMR) by analyzing the changes of microstructure, chemical composition and anti-ulcerative colitis(UC) activity before and after soil stir-frying. MethodsThe microstructure and elemental composition of AMR before and after soil stir-frying were analyzed by scanning electron microscopy-energy dispersive spectroscopy(SEM-EDS), to investigate the differences in microstructure and the underlying causes. Ultra-high performance liquid chromatography-quadrupole-time-of-flight mass spectrometry(UPLC-Q-TOF-MS) coupled with UNIFI 1.9.2 natural product analysis platform were used to analyze and identify the chemical constituents in raw and soil-fried products, and multivariate statistical methods including principal component analysis(PCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA) were used to explore the differences and sources of chemical constituents between them. A dextran sulfate sodium(DSS)-induced UC mouse model was established. The method of disease activity index(DAI) was used to evaluate the severity of intestinal inflammation. Hematoxylin-eosin(HE) staining was used to observe the pathological changes of colon tissue, enzyme-linked immunosorbent assay(ELISA) was used to detect the levels of inflammatory factors, Real-time quantitative polymerase chain reaction(Real-time PCR) and Western blot were used to analyze the expressions of key genes and proteins involved in the intestinal mucosal barrier. The 16S rRNA sequencing was used to evaluate the diversity of intestinal flora, headspace gas chromatography-mass spectrometry(HS-GC-MS) was used to explore the levels of short-chain fatty acids(SCFAs) in feces. Base on the above findings, this paper investigated the effects of raw and soil-fried AMR on the biological, chemical, mechanical and immune barriers of model animals, and the differences in pharmacological effects and underlying mechanisms from the perspective of regulating the intestinal mucosal barrier in UC mice. ResultsSEM observation revealed numerous hearth soil particles on the surface of soil-fried AMR, accompanied by bubble-like bulges. At the same time, there were many cracks and folds on the surface of the hearth soil. EDS analysis revealed that the contents of Si, Al, Mg and Ca in soil-fried AMR were significantly higher than those of raw products, and these elements constituted the primary components of hearth soil. UPLC-Q-TOF-MS combined with database comparison was used to identify the chemical constituents of raw and soil-fried AMR. In positive ion mode, a total of 132 components were identified, primarily comprising three categories of terpenoids, polyphenols and amino acids. In negative ion mode, a total of 40 components were identified, primarily polyphenolic and glycoside compounds. Among them, the contents of sesquiterpenes and polyphenolic acids were changed significantly before and after processing. Soil-fried AMR could reduce the DAI score of UC mice, alleviate the shortening of colon length, reduce the levels of pro-inflammatory factors such as interleukin(IL)-17, IL-18, γ-interferon(IFN-γ) and tumor necrosis factor(TNF)-α in serum, increase the levels of anti-inflammatory factors such as secretory immunoglobulin A(sIgA), IL-10, IL-4 and transforming growth factor-β(TGF-β) in serum, increase the expressions of key genes and proteins of intestinal mucosal barrier such as tight junction protein-1(ZO-1), Occludin, Claudin-1 and mucin 2(MUC2) in colonic mucosa, and improve the disorders of intestinal flora diversity and the levels of SCFAs(P<0.05, P<0.01). The raw and stir-fried products of AMR also exhibited the aforementioned effects, but they were weaker than the soil-fried products. Additionally, the auxiliary material hearth soil also had a certain pharmacodynamic effect. ConclusionSoil-fried AMR can enhance the protective effect on intestinal mucosal barrier in UC mice. These changes or heating-induced alterations in the microscopic structure and chemical composition of AMR may be attributed to the dual effects of adsorption of hearth soil.

ObjectiveTo investigate the effect and mechanism of modified Sini San in ameliorating intestinal mucosal barrier by observing its effects on short chain fatty acids (SCFAs) and high mobility group protein B1 (HMGB1)/receptor of advanced glycation end products (RAGE) signaling pathways in chronic stress rats. MethodsThe 50 male SD rats were randomly divided into control group,model group,low-dose modified Sini San group (7.34 g·kg-1·d-1),high-dose modified Sini San group (14.68 g·kg-1·d-1),and Fructo-oligosaccharides group (3.15 g·kg-1·d-1),with 10 rats in each group. Except for the control group,all other groups were subjected to chronic unpredictable stress/social isolation to create a chronic stress model for 6 weeks. After 4 weeks of modeling,each treatment group was given corresponding drugs by gavage for 2 weeks while modeling. The control group and model group were given the same volume of physiological saline. The effects of Modified Sini San on behaviors,body weight,Bristol score in feces and fecal moisture content in chronic stress rats were observed. Hematoxylin and eosin (HE) staining was used to observe the pathological changes in the cecum. The content of SCFAs in the cecal contents of rats were detected by Gas chromatography-mass spectrometry (GC-MS). Immunohistochemistry and Western blot were used to detect the expression of HMGB1/RAGE pathway related proteins in cecal tissue. The levels of ZO-1,Occludin,and Claudin-1 in the cecal tissue were detected by enzyme linked immunosorbent assay (ELISA). ResultsCompared with the model group,the sucrose preference rate,total distance traveled and the number of grid crossings in the open field test of rats in the low-dose modified Sini San group were obviously increased (P<0.05, P<0.01),and the immobility time in the open field test and the immobility time in the forced swimming test of rats in the low-dose and high-dose modified Sini San groups were obviously reduced (P<0.05, P<0.01). Meanwhile,the Bristol score and fecal moisture content of rats in the low and high dose groups of modified Sini San were obviously increased (P<0.05). The low-dose group of modified Sini San had intact mucosal layer structure in the cecal tissue and reduced infiltration of inflammatory cells. The content of SCFAs in the cecal contents increased,with a obviously increase in the content of acetic acid,propionic acid,butyric acid,and isovaleric acid (P<0.05, P<0.01) and the expression levels of HMGB1,RAGE,Toll-like receptor 2(TLR2),Toll-like receptor 4(TLR4),tumor necrosis factor-α(TNF-α),and nuclear factor kappa-B p65(NF-κB p65) proteins in cecal tissue were significantly decreased (P<0.05, P<0.01) in low-dose group of modified Sini San. Meanwhile,the contents of ZO-1,Occludin,and Claudin-1 in the cecal tissue were obviously increased (P<0.01) in low-dose group of modified Sini San. ConclusionModified Sini San can improve the function of intestinal mucosal barrier in chronic stress rats by increasing the content of SCFAs in the intestine and inhibiting the HMGB1/RAGE pathway.

This article systematically reviews and examines the historical evolution of Bambusae Succus as a medicinal material, covering aspects such as nomenclature, origin, geographical distribution, harvesting and processing methods, quality assessment, therapeutic effects and indications, by consulting ancient herbal texts, medical compendia, and modern literature. The aim is to provide a reference for the development and utilization of famous classical formulas containing this herb. Research indicated that Bambusae Succus was first documented in the Shennong Bencaojing during the Han dynasty, with Zhuli being the standard name used throughout history, alongside aliases like Zhuzhi, Zhuyou and Huoquan. Historically, the primary source of Bambusae Succus has been Phyllostachys nigra var. henonis(Danzhu), although other species such as Pleioblastus amarus and Bambusa emeiensis have also been used medicinally. Ancient records predominantly noted its origin in Yizhou(present-day Chengdu and surrounding areas in Sichuan) and the Wuling region(between present-day Hunan, Guangdong, Guangxi and Jiangxi provinces), while contemporary sources are mainly from regions south of the Yangtze River and southwestern China. Traditionally, Bambusae Succus was harvested from bamboo that had grown for exactly one year, today, it can be collected year-round without strict age requirements. Ancient preparation methods included direct fire roasting or dry distillation, whereas modern industrial production employs dry distillation, reflux extraction, and percolation. In terms of quality evaluation, ancient texts considered a sweet taste to be superior, while today, clarity and transparency are prioritized. Historically, Bambusae Succus was characterized as sweet and cold nature, targeting the lung and stomach meridians, with uses evolving from clearing heat and resolving phlegm to nourishing Yin, moistening dryness, and relaxing tendons and unblocking meridians. Modern descriptions classify it as sweet, bitter, and cold in nature, affecting the heart, liver, and lung meridians, with functions including clearing heat, resolving phlegm, and facilitating orifices. It is indicated for conditions such as stroke with phlegm confusion, lung heat with phlegm congestion, convulsions, epilepsy, excessive phlegm in febrile diseases, high fever with thirst, irritability during pregnancy, and tetanus, with more clearly defined applications. Based on the results of the research, it is recommended that when developing and utilizing famous classical formulas containing Bambusae Succus, the one-year-old Phyllostachys nigra var. Henonis, which has been highly praised throughout history, should be selected as the source material. Industrial production should adopt the dry distillation method. Furthermore, in-depth research should be conducted on the modern technological characterization of the traditional quality control indicator of sweet taste, and reasonable modern quality control standards should be established.

OBJECTIVE To investigate the effects of galangin on rheumatoid arthritis (RA) in rats by regulating the Janus kinase 3 (JAK3)/signal transducer and activator of transcription 3 (STAT3) pathway. METHODS Fifty male SD rats were taken, and an emulsion composed of bovine type Ⅱ collagen and Freund’s complete adjuvant was injected subcutaneously to establish an induced arthritis model. The rats that were successfully modeled were randomly divided into model group, low, medium and high dose groups of galangin (1, 5, 15 mg/kg), and methotrexate group (positive control, 2 mg/kg), with 10 rats in each group. Another 10 normal rats were taken as the normal group. Starting from the 15th day of modeling, each group of rats was gavaged with the corresponding drug solution or normal saline containing 0.5% Tween 80 once a day for 28 consecutive days. The arthritis index (AI) scores and paw volume of rats were compared before and after gavage administration. Twenty-four hours after the last administration, the serum levels of interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), IL-4 and IL-10 were determined, the pathological changes in ankle joint synovial tissue were observed, and the protein expressions of UNC-51 like kinase 1 (ULK1), Beclin-1, microtubule-associated protein 1 light chain 3 (LC3), B cell lymphoma 2 (Bcl-2), Bcl-2-associated X protein (Bax), caspase-3, JAK3, phosphorylated JAK3 (p-JAK3), STAT3 and phosphorylated STAT3 (p-STAT3) in the synovial tissue of the ankle joint were detected, as well as the fluorescence intensity of LC3-positive areas. RESULTS Compared with the model group, the pathological changes such as cellular proliferation of ankle joint synovial tissue and infiltration of inflammatory cells in rats of each administration group showed improvement. Moreover, their AI scores and paw pad volumes (on day 28 after gavage), the levels of IL-6 and TNF-α, the protein expression of Bcl-2, and the phosphorylation levels of JAK3 and STAT3 were all significantly reduced ( P <0.05). The levels of IL-4 and IL-10, the protein expressions of ULK1, Beclin-1, Bax, caspase-3 and LC3, as well as the fluorescence intensity of LC3-positive areas, were all significantly increased ( P <0.05). Moreover, the effect of galangin was in a dose-dependent manner ( P <0.05). CONCLUSIONS Galangin can induce sustained autophagy in synovial tissue cells of RA rats, promote cell apoptosis, inhibit synovial cell proliferation, and alleviate persistent inflammatory responses. The above anti-RA effects may be related to the inhibition of the JAK3/STAT3 pathway.

Objective:
To develop a prediction model for mild cognitive impairment (MCI) risk among the elderly, so as to provide a tool for MCI early screening.
Methods :
From July 2022 to September 2024, a multi-stage stratified random cluster sampling method was used to recruit permanent residents aged ≥65 years from the Xinjiang Uygur Autonomous Region as study participants. Data on sociodemographic characteristics, nutritional status, body composition indices, bone mineral density, and handgrip strength were collected through questionnaires and physical examinations. Sarcopenia was defined based on appendicular skeletal muscle index and handgrip strength. MCI was assessed using the Mini-Mental State Examination, with adjustments for educational level. Participants were randomly divided into a training set and a validation set in a 7∶3 ratio. LASSO regression and multivariable logistic regression models were employed to screen for predictors and construct an MCI risk prediction model. The predictive performance of the model was evaluated using receiver operating characteristic (ROC) curve and decision curve analysis (DCA).
Results:
A total of 1 641 participants were surveyed, including 755 males (46.01%) and 886 females (53.99%). The majority of participants were aged 65-<75 years, comprising 1 154 individuals (70.32%). MCI was detected in 517 participants, corresponding to a detection rate of 31.51%. Resultsfrom LASSO regression and multivariate logistic regression analysis showed that residence (rural, OR = 2.323, 95% CI: 1.682-3.210), age (75-<85 years, OR = 1.405, 95% CI: 1.019-1.937; ≥85 years, OR = 3.655, 95% CI: 1.696-7.875), educational level (primary school, OR = 0.341, 95% CI: 0.247-0.472; junior high school, OR = 0.255, 95% CI: 0.160-0.408; high school, OR = 0.286, 95% CI: 0.154-0.531; bachelor's degree or above, OR = 0.120, 95% CI: 0.041-0.351), history of alcohol consumption (yes, OR = 3.216, 95% CI: 2.164-4.779), risk of malnutrition (yes, OR = 1.464, 95% CI: 1.064-2.014), sarcopenia (yes, OR = 3.197, 95% CI: 2.332-4.385), and waist-to-hip ratio (abnormal, OR = 1.540, 95% CI: 1.159-2.048) were identified as predictive factors for MCI among the elderly. In the training set, the area under the ROC curve, sensitivity, and specificity were 0.788, 0.719, and 0.712, respectively. In the validation set, the corresponding values were 0.784, 0.913, and 0.542, respectively. DCA demonstrated that the model provided a higher clinical net benefit for predicting MCI risk when the risk threshold probability ranged from 0.124 to 0.764.
Conclusion
The prediction model developed in this study demonstrates good discriminative ability and clinical utility, indicating its substantial value for predicting the MCI risk among the elderly.
