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.

It is considered that "latent wind in stomach collaterals" is the core pathogenesis underlying the inflammation-caner transformation of helicobacter pylori-associated gastritis （HpAG）. The concept of "latent wind in stomach collaterals" integrates stomach wind theory， latent pathogen theory， and collateral disease theory， referring to wind pathogen deeply hidden in the stomach collaterals， characterized by both external and internal wind pathogen as well as latent pathogen that remain concealed and may be triggered under certain conditions. Accordingly， the Correa cascade is reclassified into four stages including the prodromal stage， progressive stage， transitional stage and carcinogenic stage. In the prodromal stage， the fundamental pathogenesis is described as "wind toxin invading externally with collateral deficiency and stirring of wind". In the progressive stage， wind is accompanied by qi constraint， fire pathogen， and dryness pathogen， manifesting as "wind pathogen complicated by constraint" "wind-fire agitation" and "wind-dryness interaction". In the transitional stage， "wind transforming into phlegm-drool and stomach collaterals being obstructed by stasis" is identified as a critical window for disease reversal. In the carcinogenesis stage， "wind-qi hyperactivity leading to pathological transformation， and collateral damage resulting in abdominal masses" drives tumor progression and metastasis. This paper proposes the treatment principle of "wind-dispelling throughout the entire process and stage-based treatment"， according to the pathological evolution of "collateral deficiency-collateral stagnation-collateral accumulation". In the prodromal stage， it is suggested to dispel wind and resolve toxin， fortify spleen and tonify collaterals； in the progressive and transitional stage， the method of dispelling wind pathogen， clearing phlegm and eliminating stasis should be used； in the carcinogenesis stage， it is suggested to expel wind and remove pathogens from collaterals， disperse concretions and eliminate tumors.

Objective:To examine the expression of core clock genes in the peripheral blood mononuclear cells (PBMCs) and the level of circadian disturbance-related proteins in the serum of chronic pancreatitis (CP) patients with pancreatic exocrine insufficiency (PEI), and explore their potential diagnostic value in clinical practice.Methods:The peripheral blood samples and related clinical data from 68 patients diagnosed with CP in Shanghai General Hospital from Jan 2015 to Jan 2022 were collected. Peripheral blood samples from 30 healthy individuals were used for control. The M-ANNHEIM classification system was used to stratify the clinical stages of patients with CP. The mRNA expression of the core clock genes, including Clock, Bmal1, Per1/2/3 and Cry1/2 in PBMCs was analyzed using realtime qPCR, and the expression of circadian disturbance-related proteins like TrkB, CD 36 and Rbp in serum was measured with ELISA. The receiver operating characteristic curve(ROC) and the area under curve (AUC) was used to test the efficiency for diagnozing PEI. Results:The mRNA expression of Per1 in CP patients was significantly decreased (0.76 vs 1, P<0.05), and the AUC for diagnozing PEI was 0.744 (95% CI 0.628-0.860), with a cut-off value of 0.72; and the sensitivity and specificity was 84.8% and 57.1%, respectively. The protein abundance of serum CD 36 was significantly increased in CP patients (33.85±19.74ng/ml vs 24.71±11.53 ng/ml, P<0.05); the AUC for diagnozing PEI was 0.834 (95% CI 0.735-0.932), with a cut-off value of 29.75 pg/ml; and the sensitivity and specificity was 74.3% and 84.8%, respectively. The expression of CD 36 was increased with the increase of CP clinical stage, and there were statistically significant differences between either two stages (all P value <0.05). The mRNA expression of Per1 in patients with CP in Stage Ⅰ was significantly higher than that in patients with CP in Stage Ⅱ or Ⅲ, and the differences were statistically significant ( P<0.05), but no statistical difference was found between Stage Ⅱ and Stage Ⅲ. Conclusions:The decreased expression of Per1 mRNA in PBMCs and increased level of CD 36 in serum are significantly related to the occurrence of PEI in CP, suggesting that they may have potential value for diagnozing PEI and guiding the clinical practice.

Objective To revise the determination method in the quality standard of Jingtian Zhitong cream. Methods The total saponins of angelica sinensis, Ligusticum wallichii, Rhizoma corydalis, and Panax notoginseng saponins were qualitatively identified by thin-layer chromatography (TLC). The contents of notoginsenoside R₁, ginsenoside Rg₁, and ginsenoside Rb₁ in the preparation were determined by high performance liquid chromatography (HPLC). Results TLC showed strong specificity and good resolution. The concentration of notoginsenoside R₁ showed a good linear relationship in the range of 0.1604 and 2.0050μg (r=0. 999). The concentration of ginsenoside Rg₁ showed a good linear relationship in the range of 0.8003 and 10.0035μg (r=1.000). The concentration of ginsenoside Rb₁ showed good linearity in the range of 0.6182 and 7.7275μg (r=1.000). The sample recovery rates were 101.43%, 98.75% and 100.95%, respectively. The relative standard deviation (RSD) were 2.56%, 2.71% and 2.75%, respectively. Conclusion The developed method is accurate and reliable with high sensitivity, which can be used for the quality control of Jingtian Zhitong cream.

Objective To prevent the occurrence of postoperative delirium after endoscopic surgery in patients with benign prostatic hyperplasia (BPH). Methods A total of 370 BPH patients receiving endoscopic surgery in our hospital were involved in this study. The clinical parameters including age, other systemic diseases, operation method, operation time and postoperative pain were investigated as predictive risk factors. Then the data were dealt by χ~2 test, single factor analysis or multivariate logistic regression analysis. Results Postoperative delirium occurred in 19 cases (5. 1%). Univariate analysis demonstrated that many factors were significantly correlated with the postoperative delirium in elderly patients, such as age (χ~2 = 7. 37, P<0. 05), other systemic diseases (χ~2=10.26, P<0.05), operation time (χ~2 = 19. 87, P<0.05) and postoperative pain (χ~2= 4.99, P<0. 05). The multivariate logistic regression analysis showed that age (OR = 5. 38, P< 0.05), other systemic diseases (OR = 4. 97, P<0. 05) and operation time (OR = 6. 53, P<0. 05) were important factors for postoperative delirium. Conclusions Paying more attention to the advanced age, giving sufficient preoperative preparation and reducing operation time may help to prevent postoperative delirium.
