ObjectiveTo investigate the infestation of bedbugs in a staff dormitory in Jiading District, Shanghai, to explore the measures to dispose Cimex lectularius linnaeus, so as to provide a scientific basis for the prevention and control of bedbugs. MethodsThe infestation of bedbugs in the dormitory of the company was determined through field investigation, accompanied by scientific guidance under the comprehensive control measures and an effect evaluation of the control results. ResultsA total of 114 rooms distributed in 3 dormitory buildings were investigated, with an average infestation rate of 42.11%, of which building B has the highest infestation rate of 51.52%. Six bedbug specimens were collected by visual inspection in the room, and all of them were identified as Cimex lectularius linnaeus. After a series of comprehensive control measures including environmental cleanup, aerosol elimination, replacement of wooden beds with iron frame beds, and purchase of all-inclusive mattress, the bedbug infestation rate dropped to 5.26%. ConclusionComprehensive control can effectively prevent the breeding and spread of bedbugs. Dissemination and education effort should be strengthened in case of the occurrence of bedbug infestation, together with an implementation of long-term and continuous surveillance and monitoring.

Colorectal cancer is a common and malignant tumor in the digestive tract. Invasion and metastasis of cancer cells are key factors leading to the high mortality rate and postoperative recurrence of colorectal cancer. Chemotherapy is the main treatment method for preventing recurrence of this disease. However, there are many toxic side effects in clinical application, which seriously hinder the treatment process. Therefore, it is imperative to search for efficient and low-toxicity drugs. Traditional Chinese medicine (TCM) has a long history of treating colorectal cancer and offers advantages such as safety, effectiveness, multiple targets, multiple pathways and minimal toxic side effects, which have made it increasingly popular worldwide. According to TCM, the pathogenesis of colorectal cancer is rooted in both deficiency and excess. TCM formulas mainly focus on tonifying the body to address the invasion and metastasis of colorectal cancer, such as Jianpi compound, Jianpi Xiaoai decoction, and Bushen Jiedu Sanjie decoction. TCM monomers, such as emodin, berberine, and tanshinone, mainly focus on clearing heat and removing toxin, circulating blood and transforming stasis, and resolving swelling and dispersing nodules. Signaling pathways play a crucial role for analyzing invasion and metastasis, and research has shown that pathways such as Wnt/β-catenin, phosphatidylinositol-3 kinase/protein kinase (PI3K/Akt), Janus kinase 2/signal transduction and transcription activating factor 3 (JAK2/STAT3), nuclear factors-κB (NF-κB), vascular endothelial growth factor (VEGF) play important roles in the invasion and metastasis of colorectal cancer. The invasion and metastasis of colorectal cancer can be inhibited via regulating the key proteins and related factors in these pathways. In this review, we searched various literature databases, such as PubMed, China National Knowledge Infrastructure (CNKI), and VIP, using keywords such as "colorectal cancer", "signaling pathway", "invasion and metastasis", and "traditional Chinese medicine", to summarize and analyze the relevant pathways of TCM compounds and monomers against invasion and metastasis of colorectal cancer published in the past five years. The review aims to provide new insights and references for in-depth research on the therapy for invasion and metastasis of colorectal cancer and new drug development.

AIM: To investigate the correlation of serum interleukin-35(IL-35), immunoglobulin 4/immunoglobulin(IgG4/IgG), thyroid stimulating immunoglobulin(TSI)levels with the activity and severity of thyroid associated ophthalmopathy(TAO).METHODS:Prospective study. A total of 148 TAO patients admitted to our hospital from January 2023 to July 2024 were selected as the observation group. They were assigned into an active group(75 cases)and an inactive group(73 cases)based on their activity level, and were assigned into a severe group(95 cases)and a mild group(53 cases)based on the severity of their condition; another 148 healthy patients who underwent physical examinations were regarded as the control group. The levels of IL-35, IgG4/IgG, and TSI in serum were compared between the two groups. The correlation between serum IL-35, IgG4/IgG, and TSI levels and TAO activity and severity of illness were analyzed. A multivariate Logistic regression was performed to analyze the influencing factors of TAO patients developing severe symptoms. ROC curve was applied to analyze the diagnostic value of serum IL-35, IgG4/IgG, and TSI levels for the development of severe TAO in patients.RESULTS: Compared with the control group, the serum IL-35 level in the observation group was significantly lower, while IgG4/IgG and TSI levels were significantly higher(all P<0.01). Compared with non-active TAO patients, active TAO patients had significantly lower serum IL-35 level and significantly higher IgG4/IgG and TSI levels(all P<0.01). Compared with the mild TAO patients, severe TAO patients had significantly lower serum IL-35 level and significantly higher disease duration, IgG4/IgG, and TSI levels(all P<0.01). The serum IL-35 level was negatively correlated with TAO activity and disease severity(r=-0.529, -0.554, both P<0.01), while serum IgG4/IgG level was positively correlated with TAO activity and disease severity(r=0.625, 0.663, both P<0.01). Serum TSI levels were positively correlated with TAO activity and disease severity(r=0.594, 0.607, both P<0.01). Multivariate Logistic regression analysis showed that serum IL-35, IgG4/IgG, and TSI levels were all factors influencing the progression of TAO patients to severe disease(all P<0.01). The areas under the curve(AUC)for diagnosing the progression of TAO patients to severe disease using serum IL-35, IgG4/IgG, and TSI levels were 0.868, 0.859, and 0.830, respectively. The combined AUC for the three markers was 0.955, significantly higher than that of each individual marker(Zthree factors combination-IL-35=2.893, Zthree factors combination-IL-35=3.510, Zthree factors combination-IL-35=4.157, P=0.004, <0.01, <0.01).CONCLUSION: Serum IL-35 level is significantly downregulated in TAO patients, while IgG4/IgG and TSI levels are significantly upregulated. The levels of IL-35, IgG4/IgG, and TSI are correlated with the activity and severity of TAO, and their combination has high diagnostic value for TAO developing into severe.

Polycystic ovary syndrome (PCOS) is a common endocrine and metabolic disorder affecting a substantial proportion of women of reproductive age. It is frequently associated with ovulatory dysfunction, infertility, and an increased risk of chronic metabolic diseases. A hallmark pathological feature of PCOS is the arrest of follicular development, closely linked to impaired intercellular communication between the oocyte and surrounding granulosa cells. Transzonal projections (TZPs) are specialized cytoplasmic extensions derived from granulosa cells that penetrate the zona pellucida to establish direct contact with the oocyte. These structures serve as essential conduits for the transfer of metabolites, signaling molecules (e.g., cAMP, cGMP), and regulatory factors (e.g., microRNAs, growth differentiation factors), thereby maintaining meiotic arrest, facilitating metabolic cooperation, and supporting gene expression regulation in the oocyte. The proper formation and maintenance of TZPs depend on the cytoskeletal integrity of granulosa cells and the regulated expression of key connexins, particularly CX37 and CX43. Recent studies have revealed that in PCOS, TZPs exhibit significant structural and functional abnormalities. Contributing factors—such as hyperandrogenism, insulin resistance, oxidative stress, chronic inflammation, and dysregulation of critical signaling pathways (including PI3K/Akt, Wnt/β‑catenin, and MAPK/ERK)—collectively impair TZP integrity and reduce their formation. This disruption in granulosa-oocyte communication compromises oocyte quality and contributes to follicular arrest and anovulation. This review provides a comprehensive overview of TZP biology, including their formation mechanisms, molecular composition, and stage-specific dynamics during folliculogenesis. We highlight the pathological alterations in TZPs observed in PCOS and elucidate how endocrine and metabolic disturbances—particularly androgen excess and hyperinsulinemia—downregulate CX43 expression and impair gap junction function, thereby exacerbating ovarian microenvironmental dysfunction. Furthermore, we explore emerging therapeutic strategies aimed at preserving or restoring TZP integrity. Anti-androgen therapies (e.g., spironolactone, flutamide), insulin sensitizers (e.g., metformin), and GLP-1 receptor agonists (e.g., liraglutide) have shown potential in modulating connexin expression and enhancing granulosa-oocyte communication. In addition, agents such as melatonin, AMPK activators, and GDF9/BMP15 analogs may promote TZP formation and improve oocyte competence. Advanced technologies, including ovarian organoid models and CRISPR-based gene editing, offer promising platforms for studying TZP regulation and developing targeted interventions. In summary, TZPs are indispensable for maintaining follicular homeostasis, and their disruption plays a pivotal role in the pathogenesis of PCOS-related folliculogenesis failure. Targeting TZP integrity represents a promising therapeutic avenue in PCOS management and warrants further mechanistic and translational investigation.

The clinical value of Chinese patent medicine is the core direction of the development of the traditional Chinese medicine industry. The precise clinical positioning determines the way to prove the value of the drug, and is a key link to highlight the clinical value. This paper presented a case study of clinical positioning for Chinese patent medicine, namely Qizhi Tongluo capsules, and the key technical framework of precise clinical positioning of Chinese patent medicine, which was manifested as a comparison of prescription target spectral effect, discovery of core value of prescription, and confirmation of clinical positioning trial. The technical framework was designed to address a range of issues in the realm of precise clinical positioning. Before the clinical positioning trial, based on the multi-component, multi-target, and multi-phenotype data of prescription and clinical indication, the multi-omics network analysis technology was used to identify the core value of the traditional Chinese medicine varieties and predict the potential clinical advantages. Then, based on the predicted clinical advantages, reasonable efficacy indicators were selected, and the clinical efficacy was judged and verified by dynamic and flexible innovative clinical trials to improve the success rate of clinical positioning. This research paradigm integrates "omics technology" with "evidence-based" principles and follows the "precise evidence-based" concept. This research aims to provide a new strategy and method for the precise medication and positioning of Chinese patent medicine with traditional Chinese medicine characteristics after being put into the market and provide more technical thinking for traditional Chinese medicine to move towards precise medicine.

BACKGROUND:The researchers noted that upon embedding clinical-grade catgut and polyglycolide-co-lactide threads in the normal human"Zusanli"(ST 36)acupoint,the local area displayed temporal and inflammatory stimulatory effects,resulting in thread differentiation.However,the underlying mechanism behind thread involvement remains to be studied. OBJECTIVE:To investigate the expression levels of calcitonin gene-related peptide,5-hydroxytryptamine,leukotriene B4,and bradykinin at point"Zusanli"(ST 36)in rats after embedding catgut and polyglycolide-co-lactide respectively at different time points. METHODS:110 male SD rats were divided into a blank group(10 rats),a catgut embedding group(50 rats),and a polyglycolide-co-lactide embedding group(50 rats)according to the random number table method.In the blank group,no thread was embedded.In catgut embedding group and the polyglycolide-co-lactide embedding group,the thread was embedded in the left side of the ST36 acupoint once.Tissue was collected from the left side of the ST36 acupoint area 8 hours,3,7,14,and 21 days after embedding.The expression levels of calcitonin gene-related peptide and 5-hydroxytryptamine were detected by immunohistochemistry,and the contents of leukotriene B4 and bradykinin were detected by ELISA. RESULTS AND CONCLUSION:(1)Compared with the blank group,the expression of calcitonin gene-related peptide,5-hydroxytryptamine,bradykinin,and leukotriene B4 was significantly increased in the 8 hours,3,7,14,and 21 days of the catgut embedding group(P<0.05);calcitonin gene-related peptide expression was significantly increased in 8 hours,3,7,and 14 days in the polyglycolide-co-lactide embedding group(P<0.05);the expression of bradykinin was significantly increased in 8 hours,3,and 7 days(P<0.05);the expression of leukotriene B4 was significantly increased at 8 hours,3,7,14,and 21 days(P<0.05).(2)Compared with the polyglycolide-co-lactide embedding group,the expression of calcitonin gene-related peptide was increased at 7,14,21 days after thread embedding(P<0.05),and the expression of 5-hydroxytryptamine was increased at 8 hours,3,7,14 and 21 days after thread embedding(P<0.05);contents of leukotriene B4 and bradykinin in tissues were increased at 8 hours,3,14 and 21 days after embedding(P<0.05)in the catgut embedding group.(3)The results show that calcitonin gene-related peptide,5-hydroxytryptamine,leukotriene B4,and bradykinin in the acupoint region alter after catgut embedding in the ST36 of rats,as well as the alteration of calcitonin gene-related peptide,leukotriene B4,and bradykinin is found in the acupoint region after polyglycolide-co-lactide embedding in rats,which may be one of the mechanisms involved in the local time sensitive stimulus effects caused by embedding threads at acupoints.Moreover,there is a discernible difference between the two thread types.
