OBJECTIVE:
To investigate the protective effects of stir-fried Semen Armeniacae Amarum (SAA) against aristolochic acid I (AAI)-induced nephrotoxicity and DNA adducts and elucidate the underlying mechanism involved for ensuring the safe use of Asari Radix et Rhizoma.
METHODS:
In vitro, HEK293T cells overexpressing Flag-tagged multidrug resistance-associated protein 3 (MRP3) were constructed by Lentiviral transduction, and inhibitory effect of top 10 common pairs of medicinal herbs with Asari Radix et Rhizoma in clinic on MRP3 activity was verified using a self-constructed fluorescence screening system. The mRNA, protein expressions, and enzyme activity levels of NAD(P)H quinone dehydrogenase 1 (NQO1) and cytochrome P450 1A2 (CYP1A2) were measured in differentiated HepaRG cells. Hepatocyte toxicity after inhibition of AAI metabolite transport was detected using cell counting kit-8 assay. In vivo, C57BL/6 mice were randomly divided into 5 groups according to a random number table, including: control (1% sodium bicarbonate), AAI (10 mg/kg), stir-fried SAA (1.75 g/kg) and AAI + stir-fried SAA (1.75 and 8.75 g/kg) groups, 6 mice in each group. After 7 days of continuous gavage administration, liver and kidney damages were assessed, and the protein expressions and enzyme activity of liver metabolic enzymes NQO1 and CYP1A2 were determined simultaneously.
RESULTS:
In vivo, combination of 1.75 g/kg SAA and 10 mg/kg AAI suppressed AAI-induced nephrotoxicity and reduced dA-ALI formation by 26.7%, and these detoxification effects in a dose-dependent manner (P<0.01). Mechanistically, SAA inhibited MRP3 transport in vitro, downregulated NQO1 expression in vivo, increased CYP1A2 expression and enzymatic activity in vitro and in vivo, respectively (P<0.05 or P<0.01). Notably, SAA also reduced AAI-induced hepatotoxicity throughout the detoxification process, as indicated by a 41.3% reduction in the number of liver adducts (P<0.01).
CONCLUSIONS
Stir-fried SAA is a novel drug candidate for the suppression of AAI-induced liver and kidney damages. The protective mechanism may be closely related to the regulation of transporters and metabolic enzymes.

Diabetic kidney disease(DKD),as a major causative agent of end-stage renal disease(ESRD),has a complex pathogenesis in which mitochondrial dysfunction and lipid metabolism disorders play key roles.Mitochondrial dysfunction leads to excessive reactive oxygen species(ROS)production,inhibits fatty acid β-oxidation,and creates lipotoxicity,which is the key to podocyte damage in DKD.Meanwhile,lipid metabolism disorder exacerbates ectopic accumulation of fat,activates inflammation and oxidative stress,and affects insulin signalling,which further inhibits mitochondrial function and drives DKD progression.Therefore,an in-depth understanding of the association between mitochondrial dysfunction and podocyte lipid metabolism in DKD is important for DKD treatment.This review discusses the basic profiles of DKD,mitochondrial dysfunction,and podocyte lipid metabolism,and their interactions,as well as discussing the current status of the DKD treatment,with a view to providing references for the research and treatment of DKD.

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/Aims:
Chronic hepatitis C (CHC) patients who failed antiviral therapy are at increased risk for hepatocellular carcinoma (HCC). This study assessed the potential role of metformin and statins, medications for diabetes mellitus (DM) and hyperlipidemia (HLP), in reducing HCC risk among these patients.
Methods:
We included CHC patients from the T-COACH study who failed antiviral therapy. We tracked the onset of HCC 1.5 years post-therapy by linking to Taiwan’s cancer registry data from 2003 to 2019. We accounted for death and liver transplantation as competing risks and employed Gray’s cumulative incidence and Cox subdistribution hazards models to analyze HCC development.
Results:
Out of 2,779 patients, 480 (17.3%) developed HCC post-therapy. DM patients not using metformin had a 51% increased risk of HCC compared to non-DM patients, while HLP patients on statins had a 50% reduced risk compared to those without HLP. The 5-year HCC incidence was significantly higher for metformin non-users (16.5%) versus non-DM patients (11.3%; adjusted sub-distribution hazard ratio [aSHR]=1.51; P=0.007) and metformin users (3.1%; aSHR=1.59; P=0.022). Statin use in HLP patients correlated with a lower HCC risk (3.8%) compared to non-HLP patients (12.5%; aSHR=0.50; P<0.001). Notably, the increased HCC risk associated with non-use of metformin was primarily seen in non-cirrhotic patients, whereas statins decreased HCC risk in both cirrhotic and non-cirrhotic patients.
Conclusions
Metformin and statins may have a chemopreventive effect against HCC in CHC patients who failed antiviral therapy. These results support the need for personalized preventive strategies in managing HCC risk.

OBJECTIVE:
To investigate the clinical efficacy of posterior unilateral biportal endoscopic(UBE) cervical discectomy for cervical radiculopathy under general anesthesia.
METHODS:
A retrospective analysis of 35 patients with cervical disc herniation uderwent posterior UBE cervical discectomy under general anesthesia from March 2021 to March 2023 was performed, including 17 males and 18 females, with an average age of (56.00±7.79) years old ranging from 42 to 69 years old. The non-operative treatment time was 6 to 27 weeks with an average of(16.03±4.56) weeks. MRI showed lateral cervical disc herniation in 19 cases and foraminal cervical disc herniation in 8 cases. The pathological segments distribution was as follows L4,5 in 5 cases, C5,6 in 12 cases C6,7 in 18 cases. CT/MRI was performed 1 to 3 d after surgery to evaluate the decompression, and the visual analogue scale(VAS), the Japanese Orthopedic Association(JOA) score, the stability of cervical spine surgery segment and the change of intervertebral height were recorded.
RESULTS:
All 35 patients successfully completed the operation, and the operation time was (55.88±5.02) min, the hospital stay after surgery (3.53±0.74) d. All 35 patients were followed up from 12 to 24 months with an average of (14.53±2.32) months. The VAS of preoperative, postoperative 1 day and 12 months were (7.000±0.875), (2.540±0.611), (2.143±0.772), respectively, the VAS at each time point before and after surgery were statistically significant(P<0.05). The JOA scores of preoperative, postoperative 1 day and 12 months were (11.660±0.533), (16.430±0.655), (16.540±0.611), respectively. The intervertebral height of the lesion segment at preoperative and 12 months was (6.206±0.493) mm and (6.147±0.497) mmm, respectively, and the difference was not statistically significant(P>0.05). None of the patients had cervical spine segment instability before or after surgery. According to the modified Macnab criteria, the clinical efficacy was evaluated at 12 months after operation, 32 cases were excellent, 2 cases were good, and 1 case was good.
CONCLUSION
UBE cervical discectomy is a minimally invasive, safe and effective surgical method for the treatment of single-segment cervical disc herniation, which may be an alternative to the treatment of cervical foraminal herniation, but due to the small sample size and short follow-up time, its long-term efficacy needs to be further observed.

This study aimed to evaluate the ability of rete testis thickness (RTT) and testicular shear wave elastography (SWE) to differentiate obstructive azoospermia (OA) from nonobstructive azoospermia (NOA). We assessed 290 testes of 145 infertile males with azoospermia and 94 testes of 47 healthy volunteers at Shanghai General Hospital (Shanghai, China) between August 2019 and October 2021. The testicular volume (TV), SWE, and RTT were compared among patients with OA and NOA and healthy controls. The diagnostic performances of the three variables were evaluated using the receiver operating characteristic curve. The TV, SWE, and RTT in OA differed significantly from those in NOA (all P ≤ 0.001) but were similar to those in healthy controls. Males with OA and NOA were similar at TVs of 9-11 cm 3 ( P = 0.838), with sensitivity, specificity, Youden index, and area under the curve of 50.0%, 84.2%, 0.34, and 0.662 (95% confidence interval [CI]: 0.502-0.799), respectively, for SWE cut-off of 3.1 kPa; and 94.1%, 79.2%, 0.74, and 0.904 (95% CI: 0.811-0.996), respectively, for RTT cut-off of 1.6 mm. The results showed that RTT performed significantly better than SWE in differentiating OA from NOA in the TV overlap range. In conclusion, ultrasonographic RTT evaluation proved a promising diagnostic approach to differentiate OA from NOA, particularly in the TV overlap range.
