Gouty arthritis （GA） is caused by monosodium urate（MSU） deposition due to purine metabolism disorders. In traditional Chinese medicine （TCM）， it falls under the category of "dampness-heat Bi syndrome"， with core pathogenesis involving dampness-heat accumulation and dysfunction of the spleen and kidney. The dampness-heat syndrome is the most common and the primary syndrome type during acute attacks. In Western medicine， GA is associated with purine metabolism imbalance and inflammation triggered by MSU crystals， involving pathways such as NOD-like receptor protein 3 （NLRP3） inflammasome activation and Toll-like receptor 2/4 （TLR2/4） signaling. Clinically， colchicine and similar drugs are commonly used to treat GA， although long-term use carries potential side effects. Ermiao Formula analogs originate from ancient prescriptions， including Ermiao， Sanmiao， and Simiao compound formulas. All contain Atractylodis Rhizoma and Phellodendri Chinensis Cortex. Ermiaowan follow a 1∶1 formulation ratio. Sanmiaowan add Cyathulae Radix. Simiaowan further incorporate Coicis Semen. These formulas are rich in active ingredients， including alkaloids， terpenoids， flavonoids， and sterols， and treat GA through multi-component， multi-pathway， and multi-target mechanisms. Ermiaosan primarily exerts anti-inflammatory effects by inhibiting pathways such as TLR4/nuclear factor kappa-B （NF-κB） or regulating immune responses to reduce the release of inflammatory mediators， while also suppressing xanthine dehydrogenase （XDH） and xanthine oxidase （XO） activity to decrease uric acid production. Sanmiaowan enhance uric acid-lowering and anti-inflammatory effects through the guiding herb Cyathulae Radix， while also protecting cartilage from damage. Simiaowan utilizes Coicis Semen to regulate intestinal flora， alleviate dampness-heat symptoms， and exert multi-pathway anti-inflammatory and uric acid-lowering effects. The active ingredients contribute differently to uric acid metabolism regulation， anti-inflammation， antioxidant activity， and bone repair， resulting in varying therapeutic effects due to differences in formula composition. In summary， formulas derived from Ermiaosan demonstrate significant efficacy in treating dampness-heat type GA. This review summarizes their research progress and mechanisms， providing a reference for clinical application， new drug development， and further studies.

Objective:To investigate the impact of early invasive arterial blood pressure (IBP) monitoring on survival and neurological outcomes in out-of-hospital cardiac arrest (OHCA) patients undergoing extracorporeal cardiopulmonary resuscitation (ECPR).Methods:This retrospective cohort study analyzed 44 OHCA patients receiving ECPR between January 2021 and January 2023. Patients were divided into: Early intervention group : IBP established within 3 min of ECMO initiation; Late intervention group : IBP established after ICU admission. Baseline characteristics, ECMO parameters, and clinical outcomes were compared. Multivariable logistic regression (adjusted for age, initial rhythm, etc.) and Spearman's correlation were used.Results:This study included a total of 44 patients treated with OHCA and ECPR, divided into an early intervention group of 23 cases and a late intervention group of 21 cases. The early intervention group showed significantly higher: Survival to discharge (43.5% vs. 9.5%, P<0.05), Good neurological recovery (CPC 1-2: 34.8% vs. 9.5%, P<0.05).Early intervention independently predicted survival (adjusted OR=18.84, 95% CI:1.97-179.98, P=0.01). Stratified analysis by pH (cutoff 7.0) demonstrated consistent benefits in both pH>7.0 ( aOR=0.392, 95% CI:0.106-0.678) and pH≤7.0 subgroups ( aOR=0.385, 95% CI: 0.075-0.695; interaction P=0.183). Early IBP positively correlated with CPC scores ( ρ=0.40, P=0.007). Conclusions:Early IBP monitoring significantly improves survival and neurological outcomes in OHCA-ECPR patients, supporting its integration into standardized protocols.

AIM:To evaluate and analyze the post-marketing adverse drug reaction(ADR)signals of polatuzumab vedotin,so as to provide reference for clinical safety management.METHODS:Using the FDA adverse drug event reporting system(FAERS)database and OpenVigil data platform,the ADR reports of polatuzumab vedotin were collect-ed from June 10,2019(FDA approval for market-ing)to the March 31,2023.The ADR signals were detected by using the reporting odds ratio(ROR)and proportional reporting ratio(PRR)in the pro-portional imbalance method.To increase the threshold and obtain stronger and more frequently occurring ADRs,a second screening of signals was performed.RESULTS:A total of 2 408 ADR reports related to polatuzumab vedotin were collected,and 83 ADR signals were detected after secondary screening.26 ADR signals were not mentioned in the drug instructions such as abnormal spinal mag-netic resonance imaging,increased bone resorp-tion,osteolysis,decreased aspartate aminotransfer-ase,decreased alanine aminotransferase,hypofibri-nogenemia,and pulmonary embolism.The system organ classes with a high signal counts or cumula-tive number of cases included infections and inva-sive diseases(24 signals,632 cases),various exami-nations(17 signals,675 cases),blood and lymphat-ic system diseases(11 signals,734 cases),various nervous system diseases(7 signals,153 cases),im-mune system diseases(3 signals,95 cases),system-ic diseases and various reactions at the site of ad-ministration(2 signals,145 cases),and systemic dis-eases and various reactions at the site of adminis-tration(2 signals,87 cases),etc.CONCLUSION:In addition to the common ADRs suggested by the in-structions,this study identified new ADR risk sig-nals for polatuzumab vedotin.In the clinical appli-cation of polatuzumab vedotin,in addition to the ADR mentioned in the instructions such as infec-tions,myelosuppression,peripheral neuropathies,infusion-related reactions,and abnormal liver func-tion,attention should also be paid to the risk sig-nals not mentioned such as abnormal spinal mag-netic resonance imaging,and increased bone re-sorption.

To investigate the mechanism of the major capsid protein VP5 (encoded by the UL19 gene) of oncolytic herpes simplex virus type Ⅱ (oHSV2) in regulating the antitumor function of immune cells, we constructed a mouse breast cancer cell line 4T1-iRFP-VP5-GFP stably expressing VP5 protein, near-infrared fluorescent protein (iRFP), and green fluorescent protein (GFP) by using the PiggyBac transposon system. Flow cytometry and Western blotting were employed to screen the monoclonal cell lines expressing both GFP and VP5 and examine the expression stability of UL19 in the constructed cell line. The results of SYBR Green I real-time PCR and Western blotting showed that the copies of UL19 and the expression level of VP5 protein in the 15th passage of 4T1-iRFP-VP5-GFP cells were significantly higher than those in the 4T1 cells transiently transfected with UL19, demonstrating the stable insertion of UL19 into the 4T1 cell genome. The real-time cell analysis (RTCA) was employed to monitor the proliferation of 4T1-iRFP-VP5-GFP cells, which showed similar proliferation activity to their parental 4T1 cells. Further studies confirmed that NK92 cells exhibited stronger cytotoxicity against 4T1-iRFP-VP5-GFP cells than against 4T1 cells. This study layed a foundation for elucidating the role of VP5 protein in regulating immune cells, including T cells and NK cells, via HLA-E in 4T1 cells to exert the anti-tumor function.

The drug list will be updated in time as available evidence changes， and can provide guidance for rational use of medicines for elderly patients.

Objective:To improve the understanding of the clinical features of toxic encephalopathy associated with diquat poisoning.Methods:This study collected and analyzed the diagnosis and treatment process of 7 patients with acute diquat poisoning combined with central nervous system complications admitted to the First Affiliated Hospital of Zhengzhou University from April 2021 to April 2022. "Diquat" and "Poisoning" were used as keywords to search in CNKI, Wanfang database and PubMed database, and the literature of previous cases was reviewed for summary analysis.Results:Among the 7 patients in our hospital, there were 2 males and 5 females, with an average age of 31 years (range14-57) and an average dose of 23.14 g [(10-40)g]. During the treatment, 3 patients developed irritability and convulsions, 3 patients occurred coma, and one had generalized tonic-clonic seizures. Four patients died and 3 survived, of which 2 patients returned to normal life and study, and one remained abnormal mental behavior (currently in long-term follow-up). All three survivors developed neurological symptoms later than those who died, and were awake about 30 days after taking the drug.Conclusions:Toxic encephalopathy associated with diquat poisoning has rapid progression, poor prognosis and high mortality. This study found that the survival rate of patients with > 48 h of first onset of neurological symptoms is much higher than that of patients with ≤ 48 h of first onset of neurological symptoms, while sex, age, estimated oral dose, and type of presentation of neurological symptoms for the first time have little effect on the survival rate of hospital discharge. The earlier neurological symptoms appear, the greater the likelihood of a poor prognosis.

Objective:To investigate the predictive value of a nomogram based on clinical factors and gadobenate dimeglumine (Gd-BOPTA)-enhanced MRI for predicting the expression of Glypican-3 (GPC-3) in hepatocellular carcinoma (HCC).Methods:The clinical and imaging data of 85 patients with HCC confirmed by pathology in the Provincial Hospital of Shandong First Medical University from July 2018 to June 2021 were retrospectively collected. All the patients underwent Gd-BOPTA-enhanced MRI scan before operation. According to the expression of GPC-3 by immunohistochemistry, the patients were divided into GPC-3 positive group (55 cases) and GPC-3 negative group (30 cases). The clinical data of patients were collected, including gender, age, hepatitis, cirrhosis, alpha-fetoprotein (AFP), alanine aminotransferase, aspartate aminotransferase, and glutamine transferase levels. The MRI qualitative signs including tumor margin, ring enhancement, intratumoral hemorrhage, enhanced capsule, and satellite nodules were reviewed. MRI quantitative parameters including the largest tumor diameter, Gd-BOPTA-enhanced tumor-to-liver parenchyma signal ratio (TLR) and tumor enhancement ratio (TER) in arterial phase (AP), portal venous phase (PP), and hepatobiliary phase (HBP) were calculated. The independent sample t-test or Mann-Whitney U test were used to compare the quantitative data between the two groups, and the χ2 test was used to compare the qualitative data between the two groups. Multivariate logistic regression analysis was used to identify the independent predictors of GPC-3 expression, and a nomogram model was established. The receiver operating characteristic (ROC) curves were used to evaluate the predictive performance of each independent factor and nomogram, and DeLong test was used to compare differences in area under the curve (AUC). Results:There were significant differences in AFP, tumor margin, intratumoral hemorrhage, and TLR-AP, TLR-PP and TLR-HBP between GPC-3 positive and negative groups (all P<0.05). Multivariate logistic regression results showed that AFP≥20 μg/L, intratumoral hemorrhage and TLR-HBP were independent predictors of GPC-3 positive expression in HCC (OR=3.816, 4.788, 0.001, all P<0.05). The preoperative clinical and Gd-BOPTA-enhanced MRI nomogram model for predicting GPC-3 expression in hepatocellular carcinoma was established. The AUC of AFP≥20 μg/L, intratumoral hemorrhage, TLR-HBP and nomogram model in predicting GPC-3 positive expression were 0.688, 0.697, 0.808, and 0.879, respectively. The AUC of nomogram model was significantly better than those of the other three single indicator ( Z=3.82, 4.13, 2.04, P<0.001,<0.001,=0.042). Conclusion:The nomogram model based on indicators of clinical and qualitative and quantitative Gd-BOPTA-enhanced MRI has better performance in predicting the expression of HCC GPC-3 before surgery, which is higher than those of each single indicator.
