NAFLD is the most prevalent chronic liver disease,which has become a world public health issue and the incidence rate is also showing an increasing trend.A series of liver disea-ses,such as simple fatty liver disease,NASH,liver cirrhosis,liv-er failure and liver cancer,can be collectively referred to as NAFLD.Through the study of numerous factors that influence the production of NAFLD,it has been found that the main patho-logical mechanism is excessive synthesis of fat,which is difficult to be transported into the blood,causing massive lipid accumula-tion.Alcohol has a direct damaging effect on liver and will in-hibit the breakdown of liver fat,eventually forming AFLD.How-ever,it is still controversial whether alcohol has a synergistic effect on NAFLD onset.This article provides a review on the effect of alcohol intake on NAFLD and its potential mechanisms of action.

Aim To explore the mechanism of Jiawei Shaofu Zhuyu decoction in antagonizing endometriosis fibrosis by regulating mitophagy.Methods After the animal model was constructed,the syndrome was evalu-ated by general condition,organ water content and ther-mal imaging.The curative effect was evaluated by the weight of ectopic focus and the degree of adhesion.The pathological changes were compared using HE stai-ning,transmission electron microscopy,Masson and Sir-ius red staining.The expression of PINK1 and Parkin was detected by immunohistochemistry.The expression of mRNA and protein was determined by qPCR and Western blot,and the level of serum ROS was detected by ELISA.Results The autonomic activity of model mice was weakened,the water content of organs rose,and the temperature of limbs and lower abdomen was reduced by thermal imaging.HE staining showed obvi-ous hyperplasia of ectopic epithelium and glands.Transmission electron microscopy showed mitochondrial and endoplasmic reticulum structure damage,and nor-mal autophagy structure disappeared.Masson and Siri-us red staining showed increased collagen deposition;immunohistochemistry showed decreased expression of PINK1 and Parkin in ectopic foci.qPCR and Western blot showed that the expression of PINK1,Parkin,Bec-lin1,LC3 mRNA and protein in ectopic foci of model mice decreased,the expression of p62 mRNA and pro-tein increased,and serum ROS increased.The syn-drome performance of model mice was improved after the intervention of Jiawei Shaofu Zhuyu decoction;the inflammatory infiltration of ectopic foci was relieved,the morphology of mitochondria and endoplasmic retic-ulum was restored,and normal autophagy structure ap-peared.The degree of collagen deposition and fibrosis was reduced;the mRNA and protein expression of PINK1,Parkin,Beclin1 and LC3 increased.The ex-pression of p62 mRNA and protein decreased,and the level of ROS decreased.Conclusions Jiawei Shaofu Zhuyu decoction can improve the fibrosis of ectopic le-sions in mice with endometriosis of cold-dampness sta-sis syndrome,which may be related to the regulation of mitophagy.

Neonatal sepsis is a global health problem that seriously affects the body health and life safety of newborns. It has a higher incidence in preterm infants,especially for early-onset sepsis (EOS) within 72 hours of birth. The diagnosis of neonatal EOS requires a series of examinations,and early and accurate diagnosis can improve clinical outcomes and reduce antibiotic overuse in a timely manner. At present,the commonly used biomarkers and traditional blood culture methods for EOS diagnosis have certain shortcomings,so it is urgent to find new molecular diagnostic methods. This article summarizes and compares the early and novel diagnostic methods of neonatal EOS,in order to provide a reference for clinical practice.

High altitude heart disease(HAHD)is a chronic mountain sickness in which the body is exposed to high altitude(＞2 500 m)hypobaric hypoxia environment for a long time.HAHD has high morbidity and poor prognosis,and pulmonary hypertension is the main causative mechanism for its develop-ment.The phosphodiesterase-5 inhibitor sildenafil has become a hot drug for the treatment of pulmonary hypertension.This paper reviews the progress of HAHD and discusses the mechanism of action and effectiveness of sildenafil in the treatment of HAHD,with a view to providing a basis for the treatment of HAHD with sildenafil.

Objective:To investigate the effect of chrysophanol(CHR)on cartilage injury in rats with osteoarthritis and its mechanism of regulating SIRT1/HMGB1/NF-κB signal pathway.Methods:Rat models of osteoarthritis were established and divided into negative control group,chrysophanol low(CHR-L,10 mg/kg),middle(CHR-M,20 mg/kg),high dose group(CHR-H,40 mg/kg),SIRT1 inhibitor(sirtinol 5 mg/kg)+chrysophanol high dose group(sirtinol+CHR-H),and normal healthy control group was set up.The degree of joint swelling was measured,and the inflammatory index was evaluated;the pain threshold(tenderness and heat pain)was measured;HE staining and safranine O staining were applied to detect the pathological changes of rat articular cartilage;the levels of serum inflammatory factors(IL-6,IL-1β,TNF-α)were detected by ELISA method;oxidative stress indexes(MDA,SOD,GSH-PX)were detected by micro method;TUNEL staining was used to detect apoptosis;Western blot was used to detect the protein expressions of SIRT1,HMGB1,NF-κB p65,p-NF-κB p65,MMP-13 and C-Caspase-3.Results:Compared with the normal healthy control group,the rats in negative control group had obvious pathological injury,such as destruction of articular cartilage structure,necrosis and reduction of chondrocytes,the joint swelling degree,arthritis index,levels of IL-6,IL-1β,TNF-α,content of MDA,chondrocyte apoptosis rate,expressions of apoptotic protein C-Caspase-3,HMGB1,NF-κB p65/p-NF-κB p65,MMP-13 proteins increased obviously,the tenderness threshold,heat pain threshold,activities of SOD,GSH-PX,and the expression of SIRT1 protein decreased obviously(P<0.05);compared with negative control group,the pathological injury of articular cartilage in CHR group improved obviously with the increase of dosage,the joint swelling degree,arthritis index,levels of IL-6,IL-1β,TNF-α,content of MDA,chondrocyte apoptosis rate,expression of apoptotic protein C-Caspase-3,HMGB1,NF-κB p65/p-NF-κB p65,MMP-13 proteins decreased obviously,the tenderness threshold,heat pain threshold,activities of SOD,GSH-PX,and the expression of SIRT1 protein increased obviously(P<0.05);compared with CHR-H group,sirtinol+CHR-H group was able to reverse the protective effect of CHR on cartilage injury to a certain extent.Conclusion:CHR can reduce the inflammation of articular cartilage,inhibit the apoptosis of chondrocytes and play a protective role in the cartilage injury of osteoarthritis rats by up-regulating the expression of SIRT1 and down-regulating the expressions of HMGB1 and NF-κB p65/p-NF-κB p65.

Objective To investigate the feasibility of selectively omitting ureteral stent placement after ureteroscopic lithotripsy(URL).Methods A total of 118 patients with distal ureteral calculi undergoing URL from 2021 to 2024 were enrolled.Patients were divided into a control group(indwelling ureteral stent for 2 weeks,n=86)and an observation group(no ureteral stent placement,n=32).General data,operation time,hospital stay,and total medical costs were compared between the two groups.Patients were followed 2 weeks postoperatively for assessment of flank pain visual analogue scale(VAS)scores,bladder irritation symptoms,hematuria,and incidence of urinary tract infection.Hydronephrosis was evaluated by ultrasonography 3 months after surgery.Results There was no significant difference in the general information and operation time between the two groups(P>0.05).The length of hospital stay and total treatment cost in the observa-tion group were significantly lower than those in the control group(P<0.05).Two weeks after surgery,the VAS scores of low back pain on the affected side and occurrence rates of bladder irritation symptoms,hematu-ria,and urinary tract infection in the observation group were significantly lower than those in the control group(P<0.01).Three months after operation,no hydronephrosis was observed in both groups.Conclusion It is safe and feasible to avoid indwelling ureteral stent after URL in appropriate cases.

Metachromatic leukodystrophy (MLD) is an inherited disease caused by a deficiency of the enzyme arylsulfatase A (ARSA). Lentivirus-modified autologous hematopoietic stem cell gene therapy (HSCGT) has recently been approved for clinical use in pre and early symptomatic children with MLD to increase ARSA activity. Unfortunately, this advanced therapy is not available for most patients with MLD who have progressed to more advanced symptomatic stages at diagnosis. Patients with late-onset juvenile MLD typically present with a slower neurological progression of symptoms and represent a significant burden to the economy and healthcare system, whereas those with early onset infantile MLD die within a few years of symptom onset. We conducted a pilot study to determine the safety and benefit of HSCGT in patients with postsymptomatic juvenile MLD and report preliminary results. The safety profile of HSCGT was favorable in this long-term follow-up over 9 years. The most common adverse events (AEs) within 2 months of HSCGT were related to busulfan conditioning, and all AEs resolved. No HSCGT-related AEs and no evidence of distorted hematopoietic differentiation during long-term follow-up for up to 9.6 years. Importantly, to date, patients have maintained remarkably improved ARSA activity with a stable disease state, including increased Functional Independence Measure (FIM) score and decreased magnetic resonance imaging (MRI) lesion score. This long-term follow-up pilot study suggests that HSCGT is safe and provides clinical benefit to patients with postsymptomatic juvenile MLD.
