BACKGROUND:As a mainstream surgical technique for the treatment of cervical spondylotic myelopathy through the anterior cervical subtotal decompression and bone graft fusion,it has many advantages.However,due to the high risk of this surgery and the particularity of the cervical anatomy,it is also a challenge for the surgeon.The gradual maturity of 3D printing technology and the continuous development of applications in the medical field are now able to provide more perfect personalized treatment.OBJECTIVE:To investigate the efficacy of 3D printed titanium cage cutting model in anterior cervical vertebrae subtotal decompression and bone graft fusion.METHODS:Medical records of 57 patients undergoing anterior cervical corpectomy decompression and fusion surgery admitted to the Department of Spine Surgery of Affiliated Hospital of Yan'an University from April 2021 to April 2023 were retrospectively analyzed.According to whether the 3D printed titanium cage cutting model was used in the operation,the patients were divided into the traditional titanium cage bone grafting group(control group,n=30)and the 3D printed titanium cage model group(observation group,n=27).The general data,amount of blood loss during operation,number ofC-arm X-ray machine fluoroscopy during operation,operation time,as well as anterior intervertebral edge height(H1),posterior intervertebral edge height(H2)and C2-C7 Cobb angle of the two groups measured on the cervical lateral X-ray films before,3 days and 6 months after operation were recorded and analyzed.The settling degree of the titanium cage was assessed with the distance of the height of the anterior and posterior edges of the vertebral body at 3 days and 6 months after surgery.Visual analog scale was used to evaluate neck pain and Japanese Orthopaedic Association was used to evaluate nerve function.RESULTS AND CONCLUSION:(1)Follow-up was conducted for at least 6 months.(2)The amount of intraoperative blood loss and fluoroscopy times in the observation group were less than those in the control group(P＜0.05).The operative time of the observation group was significantly shorter than that of the control group(P＜0.05).(3)There were no significant differences in C2-C7 Cobb angle,visual analog scale score,Japanese Orthopaedic Association score,anterior vertebral border height(H1)and posterior vertebral border height(H2)before surgery,3 days and 6 months after surgery between the two groups(P＞0.05).(4)There were five patients in the observation group(with severe subsidence rate of 19％)with severe subsidence at the anterior and posterior edges of the surgical segment,and seven patients in the control group(with severe subsidence rate of 23％)with severe subsidence(H1 or H2 subsidence≥3 mm)at the surgical segment 6 months after surgery.There was no significant difference in the rate of severe subsidence of titanium cage between the two groups(P＞0.05).(5)At the last follow-up,bone fusion was achieved at the operative level in both groups,and there was no statistical significance in bone graft fusion rate between the two groups(P＞0.05).(6)The results showed that the application of 3D printed titanium cage cutting model in anterior cervical corpectomy decompression and fusion surgery had the same clinical effect as that of traditional surgery,but the former could effectively reduce the fluoroscopy times of C-arm X-ray machine,the amount of blood loss and the operation time,and had unique advantages in the pruning and implantation of titanium cage during surgery.

Polycystic ovary syndrome （PCOS） is a common endocrine and metabolic disorder among women of reproductive age. Hyperandrogenism （HA）， one of its core pathological features， is closely associated with the clinical manifestations and metabolic complications of the disease. Current western medical treatments for PCOS-HA mainly include anti-androgen therapy and ovulation induction， such as short-acting oral contraceptives like Diane-35 and Yasmin. However， long-term use of these medications may result in adverse reactions like increasing the risk of liver dysfunction and exacerbating lipid metabolism disorders， with unsatisfactory long-term efficacy when used alone. Traditional Chinese medicine offers unique advantages in the treatment of PCOS-HA due to its holistic approach and multi-target regulatory mechanisms. In the view of traditional Chinese medicine， PCOS-HA is classified under the categories such as "delayed menstruation"， "amenorrhea"， and "infertility"， with kidney deficiency as the root， as well as liver stagnation and spleen deficiency as the manifestations. Phlegm and blood stasis are considered to be intertwined throughout the disease course. Modern studies have shown that traditional Chinese medicine is significantly effective in improving the androgen levels， restoring ovulation， and improving insulin resistance in PCOS-HA patients. Representative prescriptions， such as Erxian Tang， Jiawei Xiaoyaosan， Guizhi Fulingwan， and Cangfu Daotantang， exert therapeutic effects through various mechanisms including regulation of the hypothalamic-pituitary-ovarian axis， reduction of ovarian androgen synthase activity， improvement of insulin signaling pathways， and inhibition of inflammation and oxidative stress， which demonstrates the characteristics of comprehensive treatment with traditional Chinese medicine. Based on the perspectives of etiology and pathogenesis of traditional Chinese medicine， modern medical cognition， typical prescriptions， and action mechanisms， this paper reviewed the research progress of traditional Chinese medicine in the treatment of PCOS-HA， aiming to provide a reference for in-depth research and clinical applications in this field.

ObjectiveTo investigate the therapeutic efficacy of Qizhi Tongluo granules on proteinuria in membranous nephropathy （MN） and its potential protective effects and underlying mechanism against endoplasmic reticulum stress. MethodsAfter 70 Sprague-Dawley （SD） rats were adaptively fed for one week， the MN rat model was established by injecting cationic bovine serum albumin （C-BSA） into the tail vein. Rats were divided into the normal group， model group， low-dose Qizhi Tongluo granules group （2.43 g·kg^-1）， medium-dose group （4.86 g·kg^-1）， high-dose group （9.72 g·kg^-1）， and benazepril group （0.01 g·kg^-1）， with 10 rats in each group. Treatment was administered for four weeks. The 24-hour urinary total protein （UTP） content， as well as the levels of reactive oxygen species （ROS）， malondialdehyde （MDA）， and glutathione peroxidase （GPX） in renal tissues， were measured. Renal pathological changes were assessed using immunoglobulin G （IgG） staining， periodic acid-silver methenamine （PASM） staining， and transmission electron microscopy （TEM）. The localization and expression levels of glucose-regulated protein 78 （GRP78）， phosphorylated inositol-requiring enzyme 1α （p-IRE1α）， phosphorylated protein kinase R-like endoplasmic reticulum kinase （p-PERK）， activating transcription factor 4 （ATF4）， nuclear factor erythroid 2-related factor 2 （Nrf2）， and 2'-5' oligoadenylate synthetase-like protein 1 （OASL1） in rat kidneys were detected by immunohistochemistry （IHC）. The mRNA and protein expression levels of Nrf2， thioredoxin 1 （Trx1）， thioredoxin-interacting protein （TXNIP）， and OASL1 in rat kidneys were measured using real-time quantitative polymerase chain reaction （Real-time PCR） and Western blot analysis. ResultsCompared with the normal group， UTP levels were significantly increased in the model rats （P<0.05）， with obvious renal pathological damage. GPX content levels were significantly decreased in renal tissue （P<0.05）， while ROS and MDA content levels were significantly increased （P<0.05）. The expression of GRP78， p-IRE1α， p-PERK， and ATF4 proteins was significantly increased in the kidneys （P<0.05）， while the mRNA and protein expression levels of Trx1 and Nrf2 were significantly decreased （P<0.05）. The mRNA and protein expression levels of TXNIP and OASL1 were significantly increased （P<0.05）. Compared with the model group， the UTP levels of rats in the Qizhi Tongluo granules groups and the benazepril group decreased to varying degrees （P<0.05）， and renal pathological damage was significantly alleviated. The GPX content in renal tissue was significantly increased （P<0.05）， while the ROS and MDA levels were significantly decreased （P<0.05）. The expression of GRP78， p-IRE1α， p-PERK， and ATF4 proteins in the kidney was significantly decreased （P<0.05）. The mRNA and protein expression levels of Trx1 and Nrf2 were significantly increased （P<0.05）， while the mRNA and protein expression levels of TXNIP and OASL1 were significantly decreased （P<0.05）. ConclusionQizhi Tongluo granules alleviates proteinuria in MN rats by modulating the Nrf2/OASL1 signaling pathway in renal tissues to reduce endoplasmic reticulum stress， which represents its underlying mechanism.

ObjectiveTo investigate the clinical effects and safety of Shuhe Granules （舒和颗粒） in patients with rheumatoid arthritis （RA） comorbid with insomnia. MethodsA single-arm prospective exploratory design was adopted. Thirty RA patients comorbid with insomnia and diagnosed with the traditional Chinese medicine （TCM） syndrome of kidney-heart deficiency and qi-blood disharmony were enrolled. On the basis of maintaining their original RA treatment regimens， all patients received oral Shuhe Granules， one dose per day， for 12 consecutive weeks. The outcomes were assessed before treatment and at weeks 4， 8， and 12 after treatment. Sleep and related psychosomatic function were evaluated using the insomnia severity index （ISI）， Pittsburgh sleep quality index （PSQI）， fatigue severity scale （FSS）， patient health questionnaire-9 （PHQ-9）， generalized anxiety disorder-7 （GAD-7）， and Montreal cognitive assessment （MoCA） scores. RA-related assessments included the 28-joint disease activity score based on C-reactive protein （DAS28-CRP）， pain visual analog scale （VAS）， tender joint count （TJC28）， swollen joint count （SJC28）， morning stiffness duration， and health assessment questionnaire （HAQ） score. Laboratory parameters included erythrocyte sedimentation rate （ESR）， serum C-reactive protein （CRP）， anti-cyclic citrullinated peptide antibody （anti-CCP）， and rheumatoid factor （RF） levels. A literature-based historical control group was established through literature retrieval and meta-analysis. The ISI， PSQI， DAS28-CRP， and pain VAS scores were compared between the treatment group in the present study and the historical control group. Safety assessments were also performed. ResultsCompared with baseline before treatment， ISI and PSQI scores decreased at weeks 4， 8， and 12， while MoCA scores increased at weeks 4， 8， and 12. FSS scores decreased at weeks 4 and 12. At weeks 8 and 12， GAD-7 scores， DAS28-CRP scores， duration of morning stiffness， TJC28， and SJC28 were reduced. At week 12， PHQ-9， pain VAS， and HAQ scores significantly decreased （P＜0.05）. FSS and DAS28-CRP scores at week 12 were lower than those at week 4， and CRP levels at week 8 were lower than those at week 4 （P＜0.05）. Compared with the historical control group， the treatment group showed superior improvement in ISI and PSQI scores （P＜0.001）； however， no statistically significant differences were observed between the two groups in DAS28-CRP or pain VAS scores （P＞0.05）. No serious adverse events occurred during the study， and the 4 reported mild adverse events were all considered unrelated to the study medication. ConclusionShuhe Granules significantly improve sleep quality， fatigue， emotional status， cognitive function， RA-related symptoms， and joint function in patients with RA comorbid insomnia， with good safety and tolerability.

Chronic hepatitis B （CHB） is a significant public health issue worldwide. The persistent presence of covalently closed circular DNA of the hepatitis B virus （HBV） and the integration of the viral genome are the main obstacles limiting the achievement of virological cure in CHB. Functional cure has now become an important goal in antiviral therapy for CHB， and its accurate determination and efficacy prediction rely on a comprehensive assessment of multidimensional diagnostic markers. This article systematically reviews the research advances in diagnostic markers associated with functional cure in CHB， focusing on the clinical value of serological and virological indicators （HBsAg quantification and HBV DNA）， genomic， transcriptomic， proteomic， and metabolomic markers， and indicators associated with host innate immunity and adaptive immunity. Furthermore， it discusses future research directions such as the establishment of unified detection standards and the construction of predictive models combining multiple markers， in order to promote the precise assessment and individualized management of functional cure in CHB.

Objective To identify core targets of hepatocellular carcinoma (HCC) by using bioinformatics and specific algorithms, explore their relationships with immune cells, and investigate the causal relationships between immune cells and HCC through Mendelian randomization. Methods Relevant genes associated with the development of HCC were screened using the GEO and TCGA databases. Immune infiltration analysis was conducted using GSVA and CIBERSORT algorithms. A bidirectional Mendelian randomization analysis was then performed to explore the causal relationships between immune cells and HCC. Results A total of 284 HCC-related genes were identified, with 120 genes recognized within the protein interaction network. Immune infiltration analysis revealed significant correlations between key genes and immune cells. Mendelian randomization results indicated that HLA DR on CD33⁺ HLA DR⁺ CD14dim (OR=1.097, 95%CI: 1.002–1.201, P=0.045, P_Bonferroni=0.091) and CD8 on CD28⁺ CD45RA⁺ CD8⁺ T cell (OR=1.123, 95%CI: 1.027–1.228, P=0.011, P_Bonferroni=0.022) were the risk factors for HCC. Conversely, HLA DR⁺⁺ monocyte absolute count was identified as a protective factor for HCC (OR=0.812, 95%CI: 0.702–0.938, P=0.005, P_Bonferroni=0.139). Conclusion The occurrence and development of liver cancer may be related to CDK1, CCNB1, and CDC20, showing a high degree of correlation with Th2 cells, T helper cells, Th17 cells, and DCs. Mendelian randomization shows that HLA DR on CD33⁺HLA DR⁺ CD14dim and CD8 on CD28⁺CD45RA⁺CD8⁺T cells are associated with an increased risk of HCC. The risk of hepatocellular carcinoma is associated with a decrease in the level of HLA DR⁺⁺monocyte absolute count.

Fecal microbiota transplantation (FMT) technology originated in China during the Eastern Jin Dynasty and has rapidly developed over the past two decades, becoming a primary method for studying the causal relationship between gut microbiota and the occurrence and progression of diseases. At the same time, the therapeutic effects of FMT in the field of gastrointestinal diseases have gained widespread recognition and are gradually expanding into other disease areas. The FMT procedure is relatively complex, and there is currently no standardized method; its success is influenced by various factors, including the donor, recipient, processing of the fecal material, and the method of implantation. Given the increasingly recognized relationship between gut microbiota and various diseases, FMT has become a research hotspot in both scientific studies and clinical applications, achieving a series of significant advancements. To help researchers better understand this technology, this paper will outline the development history of FMT, summarize common operational methods in research and clinical settings, review its application progress, and look forward to future development directions.
