ObjectiveTo study the effect of the herb pair Mori Folium-Ginseng Radix et Rhizoma (HMG) on glucose and lipid metabolism in the mouse model of type 2 diabetes mellitus and decipher the possible treatment mechanism. MethodsThe db/db mice were chosen as the mouse model of type 2 diabetes mellitus and then treated with HMG at low and high doses (1.56, 3.12 g∙kg-1, respectively) or metformin (0.26 g∙kg-1) by gavage for 6 weeks. The normal group and the model group were treated with double distilled water at the same time according to body weight. The 8-h fasting blood glucose and body weight were measured once a week. The oral glucose tolerance test (OGTT) was conducted at the 6th week of dosing. The mice were sacrificed after the end of dosing. Serum levels of lipids [total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL), and low-density lipoprotein cholesterol (LDL)], liver function indicators [aspartate aminotransferase (AST) and alanine aminotransferase (ALT)], non-esterified fatty acids (NEFA), glycosylated serum protein (GSP), serum glucose (GLU), fasting insulin (FINS), and renal function indicators [creatinine (Crea) and blood urea nitrogen (BUN)] were measured by enzyme-linked immunosorbent assay. The protein levels of peroxidase proliferator-activating receptor gamma (PPARγ), acetyl coenzyme A carboxylase (ACC), and sterol regulatory element-binding protein-1 (SREBP-1) were determined by Western blot. The pathological changes in the liver and pancreas were examined. ResultsCompared with the normal group, the model group presented increased body weight, elevated levels of blood glucose, TG, TC, AST, ALT, GLU, NEFA, GSP, and HDL-C, up-regulated protein levels of ACC and SREBP-1, and down-regulated protein level of PPARγ (P<0.01). Meanwhile, the model group presented a large amount of lipid droplets and steatosis in the liver, as well as karyopyknosis and lymphocyte infiltration in the pancreas. Compared with the model group, the high- and low-dose HMG groups showed decreased body weight, declined levels of blood glucose, TG, TC, AST, ALT, GLU, NEFA, and GSP, and elevate level of HDL-C (P<0.05, P<0.01). Moreover, the two groups showcased reduced lipid droplets and steatosis in the liver, as well as enlarged islets with clear boundaries and alleviated lymphocyte infiltration and karyopyknosis. Western blot results showed that the high-dose herb pair group demonstrated down-regulated protein levels of ACC and SREBP-1 and up-regulated protein level of PPARγ (P<0.01). ConclusionThe HMG can effectively improve the glucose and lipid metabolism in db/db mice by regulating the expression of PPARγ, SREBP-1, and ACC.

Respiratory syncytial virus (RSV) is an enveloped, negative-sense, single-stranded RNA virus of the Orthopneumovirus genus of the Pneumoviridae family in the order Mononegavirales. RSV can cause acute upper and lower respiratory tract infections, sometimes with extrapulmonary complications. The disease burden of RSV infection is enormous, mainly affecting infants and older adults aged 75 years or above. Currently, treatment options for RSV are largely supportive. Prevention strategies remain a critical focus, with efforts centered on vaccine development and the use of prophylactic monoclonal antibodies. To date, three RSV vaccines have been approved for active immunization among individuals aged 60 years and above. For children who are not eligible for these vaccines, passive immunization is recommended. A newly approved prophylactic monoclonal antibody, Nirsevimab, which offers enhanced neutralizing activity and an extended half-life, provides exceptional protection for high-risk infants and young children. This review provides a comprehensive and detailed exploration of RSV's virology, immunology, pathogenesis, epidemiology, clinical manifestations, treatment options, and prevention strategies.

Objective:To evaluate the efficacy and safety of a China original liquid pulsation system for the treatment of meibomian gland dysfunction (MGD).Methods:A non-randomized controlled clinical trial was conducted.Twenty-two patients (44 eyes) diagnosed with MGD in Eye and ENT Hospital of Fudan University from February to August 2022 were enrolled.The patients were assigned into two groups according to their willingness.Of the 22 patients (44 eyes), 10 patients (20 eyes) in single liquid pulsation system group were treated with single liquid pulsation system for 12 minutes, and 12 patients (24 eyes) in intense pulsed light (IPL) group were treated with a course (4 times) of IPL, warm compresses and meibomian gland massage at three-week intervals.There was no difference in age and other baseline clinical indexes between the two groups (all at P<0.05). The meibum grading, quality grading of tear film lipid layer, Symptom Assessment Questionnaire in Dry Eye (SANDE) questionnaire score, first and average tear breakup time (BUT), corneal fluorescein sodium staining (CFS) score, tear meniscus height (TMH), and the area of meibomian gland loss were determined at baseline, 1 and 3 months after treatment.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Eye and ENT Hospital of Fudan University (No.2021069). Written informed consent was obtained from each patient before any medical examination. Results:Statistically significant group effects and time effects were found in the quality of tear film lipid layer ( Hgroup=4.39, P=0.036, Htime=6.30, P=0.043) and average BUT ( Fgroup=4.41, P=0.038; Ftime=4.08, P=0.049) in the two groups.The meibum grading, first BUT and TMH 1 and 3 months after treatment were significantly better than before treatment in single liquid pulsation system group (all at P<0.05). Compared with before treatment, there was no significant improvement in the meibum grading, distribution of tear film lipid, first BUT and TMH at 1 and 3 months after treatment in IPL group (all at P>0.05). In both groups, the SANDE and CFS scores 1 and 3 months after treatment were better than those before treatment, showing statistically significance (all at P<0.05). In terms of safety, neither instrument-related adverse events nor extra complaints of discomfort were reported in the single liquid pulsation system group.In both groups, the number of patients with positive CFS staining significantly decreased, and no new cases with positive CFS appeared after treatment. Conclusions:This China original liquid pulsation system is a safe and effective physical therapy in improving tear film dysfunction and ocular surface symptoms of MGD patients within 3 months after treatment.

OBJECTIVE To explore the difference in th e mechanis m of baicalein and wogonin inhibiting the energy metabolism of hepatoma cells. METHODS Human hepatoma HepG 2 cells were divided into blank control group (without medicine),different dose groups of baicalein and wogonin (1.25,2.5,5,10 and 20 μmol/L). The effects of baicalein and wogonin on the viability of HepG 2 cells were detected by MTT assay. HepG 2 cells were divided into blank control group (without medicine),baicalein group and wogonin group. After administration ,the concentration of ATP in cell was detected by enhanced ATP kit. The levels of cell glycolysis and mitochondrial energy metabolism were evaluated by glycolysis and mitochondrial pressure test kit ;the affinity of baicalein and wogonin with key enzymes of energy metabolism was predicted by molecular docking ,and the key enzymes of energy metabolism with high affinity were screened ;the expression of key enzymes of energy metabolism was detected by Western blot. RESULTS Within the dose range of 2.5-20 μmol/L,the half inhibitory concentrations of baicalein and wogonin were 12.84 and 24.09 μmol/L;baicalein 1.25 μmol/L and wogonin 2.5 μmol/L had no effect on cell viability ,so it was selected as the dosage for subsequent experiments. Compared with blank control group ,the concentration of ATP in HepG 2 cells decreased significantly in baicalein group and wogonin group (P<0.05);the inhibitory effects on basic acidification rate of HepG 2 cells in wogonin group were significantly stronger than those of baicalein group (P<0.05),but there was no significant difference between them on the basic oxygen consumption rate (P>0.05);baicalein had strong binding to pyruvate kinase M 2 and mitochondrial enzyme complexes Ⅰ(CⅠ),C Ⅱ and C Ⅳ,while wogonin only had strong binding to pyruvate kinase M 2; wogonin could significantly down-regulate the protein expressions of hexokinase ,phosphofructokinase,pyruvate kinase M 2,CⅠ, C Ⅱ and C Ⅳ(P<0.05),but there was no statistical significance in the effect of baicalein on the regulation of these enzymes (P> 0.05). CONCLUSIONS Both baicalein and wogonin can inhibit the energy metabolism of hepatoma HepG 2 cells,but the mechanism is different :the effect of baicalein is related to the activity of key enzymes ,while the effect of wogonin is related to the inhibition of the expression of key enzymes of energy metabolism.

The first-line nucleos(t)ide analogs (NAs) based antiviral drugs can effectively inhibit HBV replication and slow down the progression of chronic hepatitis B. However, about 20% of patients receiving standard NAs antiviral therapy will still develop low-level viremia (LLV). Therefore, understanding the occurrence mechanism of LLV will help to optimize antiviral treatment regimens and improve the prognosis of patients with chronic hepatitis B. This article systematically summarizes the possible mechanisms of LLV occurrence, and the important factor of NAs failure. Taking into account the unique limitations of NAs competitive inhibition of virus replication, weakening host's immune response is not enough to directly eliminate infected hepatocytes. This makes it difficult to achieve a complete virological response in some patients with the active compensatory proliferation of residual infected hepatocytes and the accompanying effective removal or dilution of covalent, closed, circular DNA (cccDNA) pools. Therefore, it is speculated that activating host immunity can eliminate infected liver cells and may be more conducive to address LLV.
