To investigate the impact of preoperative serum follicle-stimulating hormone (FSH) levels on the probability of testicular sperm retrieval, we conducted a study of nonobstructive azoospermic (NOA) men with different testicular volumes (TVs) who underwent microdissection testicular sperm extraction (micro-TESE). A total of 177 NOA patients undergoing micro-TESE for the first time from April 2019 to November 2022 in Shenzhen Zhongshan Obstetrics and Gynecology Hospital (formerly Shenzhen Zhongshan Urology Hospital, Shenzhen, China) were retrospectively reviewed. The subjects were divided into four groups based on average TV quartiles. Serum hormone levels in each TV group were compared between positive and negative sperm retrieval subgroups. Overall sperm retrieval rate was 57.6%. FSH levels (median [interquartile range]) were higher in the positive sperm retrieval subgroup compared with the negative outcome subgroup when average TV was <5 ml (first quartile [Q1: TV <3 ml]: 43.32 [17.92] IU l -1 vs 32.95 [18.56] IU l -1 , P = 0.048; second quartile [Q2: 3 ml ≤ TV <5 ml]: 31.31 [15.37] IU l -1 vs 25.59 [18.40] IU l -1 , P = 0.042). Elevated serum FSH levels were associated with successful micro-TESE sperm retrieval in NOA men whose average TVs were <5 ml (adjusted odds ratio [OR]: 1.06 per unit increase; 95% confidence interval [CI]: 1.01-1.11; P = 0.011). In men with TVs ≥5 ml, larger TVs were associated with lower odds of sperm retrieval (adjusted OR: 0.84 per 1 ml increase; 95% CI: 0.71-0.98; P = 0.029). In conclusion, elevated serum FSH levels were associated with positive sperm retrieval in micro-TESE in NOA men with TVs <5 ml. In men with TV ≥5 ml, increases in average TVs were associated with lower odds of sperm retrieval.

OBJECTIVE: To identify prognostic genes associated with lysosome-dependent cell death (LDCD) in patients with gastric cancer (GC). METHODS: Differentially expressed genes (DEGs) were identified using The Cancer Genome Atlas - Stomach Adenocarcinoma. Weighted gene co-expression network analysis was performed to identify the key module genes associated with LDCD score. Candidate genes were identified by DEGs and key module genes. Univariate Cox regression analysis, and least absolute shrinkage and selection operator regression and multivariate Cox regression analyses were performed for the selection of prognostic genes, and risk module was established. Subsequently, key cells were identified in the single-cell dataset (GSE183904), and prognostic gene expression was analyzed. Cell proliferation and migration were assessed using the Cell Counting Kit-8 assay and the wound healing assay. RESULTS: A total of 4,465 DEGs, 95 candidate genes, and 4 prognostic genes, including C19orf59, BATF2, TNFAIP2, and TNFSF18, were identified in the analysis. Receiver operating characteristic curves indicated the excellent predictive power of the risk model. Three key cell types (B cells, chief cells, and endothelial/pericyte cells) were identified in the GSE183904 dataset. C19orf59 and TNFAIP2 exhibited predominant expression in macrophage species, whereas TNFAIP2 evolved over time in endothelial/pericyte cells and chief cells. Functional experiments confirmed that interfering with C19orf59 inhibited proliferation and migration in GC cells. CONCLUSION C19orf59, BATF2, TNFAIP2, and TNFSF18 are prognostic genes associated with LDCD in GC. Furthermore, the risk model established in this study showed robust predictive power.

Rheumatoid arthritis (RA) is a prevalent autoimmune disease characterized by chronic inflammation and excessive proliferation of the synovium. Currently, treatment options focus on either reducing inflammation or inhibiting synovial hyperplasia. However, these modalities are unsatisfactory in achieving the desired therapeutic outcomes. Halofuginone hydrobromide (HF), an herbal active ingredient, has demonstrated pharmacological effects of both anti-inflammation and inhibition of synovial hyperplasia proliferation. However, HF's medical efficacy is limited due to its poor water solubility, short half-life (t _1/2), and non-target toxicity. In the current study, by using the advantages of nanotechnology, we presented a novel dual-targeted nanocomplex, termed HA-M@P@HF NPs, which consisted of a hyaluronic acid (HA)-modified hybrid membrane (M)-camouflaged poly lactic-co-glycolic acid (PLGA) nanosystem for HF delivery. These nanocomplexes not only overcame the limitations of HF but also achieved simultaneous targeting of inflammatory macrophages and human fibroblast-like synoviocytes-RA (HFLS-RA). In vivo experiments demonstrated that these nanocomplexes effectively suppressed immune-mediated inflammation and synovial hyperplasia, safeguarding against bone destruction in rats with adjuvant-induced arthritis (AIA). Remarkable anti-arthritic effects of these nanocomplexes were accomplished through promoting repolarization of M1-to-M2 macrophages and apoptosis of HFLS-RA, thereby offering a promising therapeutic strategy for RA.

Objective To investigated the correlation between the effects of the compatibility of fried Paeoniae Radix Alba-Glycyrrhizae Radix et Rhizoma Praeparata cum Melle on chemical composition and anti-inflammatory effects.Methods An HPLC-DAD method was employed for the simultaneous determination of various components of fried Paeoniae Radix Alba-Glycyrrhizae Radix et Rhizoma Praeparata cum Melle,including paeoniflorin,albiflorin,benzoylpaeoniflorin,oxypaeoniflorin,glycyrrhizic acid and glycyrrhizin.An adjuvant-induced arthritis rat model was established.Administration groups were given fried Paeoniae Radix Alba,Glycyrrhizae Radix et Rhizoma Praeparata cum Melle,and fried Paeoniae Radix Alba-Glycyrrhizae Radix et Rhizoma Praeparata cum Melle liquid by gavage for 2 weeks,respectively.Enzyme-linked immunosorbent assay was conducted to detect the levels of inflammatory factors IL-1β,TNF-α and PGE2 in serum of each group.Factorial design,bivariate correlation analysis,and multiple linear regression were employed to explore the effect of compatibility on chemical composition and its correlation with anti-inflammatory efficacy.Results The established HPLC-DAD analysis method revealed a significant increase in the content of oxypaeoniflorin,albiflorin and benzoylpaeoniflorin following the compatibility of fried Paeoniae Radix Alba-Glycyrrhizae Radix et Rhizoma Praeparata cum Melle(P<0.05).Compared with the model group,the contents of IL-1β,TNF-α and PGE2 in serum of each administration group decreased(P<0.01),and the contents of IL-1β,TNF-α and PGE2 in serum of compatibility group were lower than fried Paeoniae Radix Alba group and Glycyrrhizae Radix et Rhizoma Praeparata cum Melle group(P<0.05,P<0.01).The results from the factorial design indicated the presence of an interaction effect between fried Paeoniae Radix Alba-Glycyrrhizae Radix et Rhizoma Praeparata cum Melle.Bivariate correlation analysis results showed negative correlations between oxypaeoniflorin,albiflorin,paeoniflorin,glycyrrhizin,benzoylpaeoniflorin and glycyrrhizic acid with the contents of IL-1β,TNF-α and PGE2,respectively.Multiple linear regression results revealed that glycyrrhizin and glycyrrhizic acid were negatively correlated with the contents of IL-1β,TNF-α and PGE2.Conclusion The established method for analyzing multiple constituents in the compatibility of fried Paeoniae Radix Alba-Glycyrrhizae Radix et Rhizoma Praeparata cum Melle is straightforward,rapid,highly specific,accurate,and reliable,suitable for quality evaluation and control.The compatibility of fried Paeoniae Radix Alba-Glycyrrhizae Radix et Rhizoma Praeparata cum Melle can inhibit the expressions of IIL-1β,TNF-α and PGE2,and the content of chemical composition is correlated with anti-inflammatory effects.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Background and Aims:The incidence of papillary thyroid carcinoma (PTC) has shown a significant upward trend. Given its favorable prognosis,there is a growing trend toward de-escalating its treatment to improve patients' quality of life. Pathologists have renamed the encapsulated follicular variant of PTC with indolent biological behavior as noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP),providing a theoretical basis for treatment de-escalation. However,challenges persist in the clinical pathological diagnosis of NIFTP,and it is still predominantly managed as classical PTC in most cases. This study was performed to explore the clinicopathologic diagnostic characteristics,surgical challenges,and prospects for de-escalation treatment of NIFTP.Methods:The clinical data of 33 patients with thyroid disease who were admitted to Xuanwu Hospital Capital Medical University from November 2017 to December 2022 and confirmed as NIFTP by final paraffin pathology were retrospectively analyzed. Results:Among the 33 NIFTP patients,there were 11 males and 22 females,with an average age of 50 years. Tumor sizes ranged from 0.6 to 7.5 cm. There were 31 cases of solitary NIFTP tumor and 2 cases of multifocal tumors (each involving 2 sites). Eleven patients had coexisting PTC (one lesion in each case),with 4 lesions located on the same side as the NIFTP and 7 on the opposite side. All patients underwent surgical treatment,including 27 cases of conventional open surgery and 6 cases of endoscopic surgery. Suspicious or potentially malignant lesions were treated according to PTC surgical principles (lobectomy of the affected side plus central compartment lymph node dissection on the same side). Preoperative ultrasonography revealed that the nodules were predominantly hypoechoic,relatively regular in shape,well-defined,often accompanied by calcifications,and had a longitudinal-to-transverse diameter ratio of<1. TI-RADS classifications were as follows:5 cases as grade 3,9 cases as grade 4a,and 11 cases as grade 4b or higher. Among 29 patients who underwent preoperative fine-needle aspiration,1 case was diagnosed as atypia of undetermined significance/follicular lesion of undetermined significance (AUS/FLUS),12 as follicular neoplasm/suspicious for follicular neoplasm (FN/SFN),12 as suspicious for malignancy (SUS),and 4 as PTC. BRAFV600E mutation testing was performed postoperatively in 25 cases,and 7 mutations were detected,all in cases with concomitant PTC.Conclusion:The introduction of the NIFTP concept provides a foundation for de-escalation or individualized treatment of certain less aggressive thyroid tumors. However,the preoperative and intraoperative diagnosis of NIFTP remains challenging in clinical practice. More precise preoperative diagnostic criteria and methods are needed to enable surgeons to adjust treatment decisions accordingly.
