BACKGROUNDTo evaluate the inhibitive effect of combination of 3TC with Ara-AMP against HBV in vitro.

METHODSUsed 2.2.15 cell as target cell. With radioimmunological technique and blot slot, the inhibitive effect of 3TC, Ara-AMP and the combination of both against the HBsAg, HBeAg and intracellular HBV DNA were investigated.

RESULTSThe inhibitive ratio of Ara-AMP against HBsAg, HBeAg was 45.48% and 41.46% respectively when its concentration was 400.0 microgram/ml. Although 3TC also has inhibitive effect in its experimental concentration, its effect is weaker. When Ara-AMP 50.0 microgram/ml was combined with 3TC 1.25 and 5.00 microgram/ml respectively, the inhibitive ratio against HBsAg were 19.92% and 17.32% respectively. Compared with using same concentration 3TC alone, the difference of results was significant (P<0.05). But when compared with using the same concentration Ara-AMP alone, the difference of results had no statistical significance (P <0.05). Remarkable inhibitive effects of combination of 3TC with Ara-AMP against HBeAg were n ot found. When 3TC 5.00 microgram/ml was combined with Ara-AMP 12.5 and 50.0 microgram/ml respectively, the inhibitive ratio against HBV DNA was 45.90% and 50.36% respectively. Comparing the content of HBV DNA in these groups with that of control group and the groups using the same concentration 3TC and Ara-AMP alone, the differences were significant (P <0.05).

CONCLUSIONSCombination of 3TC with Ara-AMP could enhance the inhibitive effects against HBV DNA.

BACKGROUND:Cholecystokinin as an endogenous neuroprotective factor in the nervous system has garnered increasing attention. Findings from previous animal studies show that cholecystokinin can effectively promote the regeneration of the injured peripheral nerve. On this basis, further clinical trials wil be performed to observe whether local application of cholecystokinin at nerve anastomosis can promote peripheral nerve regeneration.
METHODS/DESIGN:As a prospective randomized controled trial, this study wil enrol 100 patients with complete rupture of the peroneal nerve, who wil be randomly divided into two groups: after nerve suture and partial gelatin sponge infiltration at nerve anastomosis, the patients wil be treated with 8 nmol/kg cholecystokinin (treatment group) or saline (control group). At 6, 12, 24 weeks after treatment, common peroneal nerve conduction velocity and electromyography and nerve fiber morphology wil be detected; the clinical efficacy at the last folow-up wil be assessed; and al adverse events during the folow-up wil be recorded to assess the therapeutic efficacy and safety.
DISCUSSION:In this study, cholecystokinin as an inducing agent for nerve growth factor synthesis wil be observed and studied, with a view to providing a new idea for seeking peripheral nerve therapy.
ETHICAL APPROVAL: The study protocol was approved by the Medical Ethics Committee of the Affiliated Hospital of Putian University (approval No. 2014116). Written informed consent wil be obtained from patients before treatment.

Objective: To explore the relationship between sleep characteristics, physical activity patterns, with depressive and anxiety symptoms in college students, so as to provide reference for student mental health promotion. Methods: From September to November 2023, a convenience sampling method was used to select 7 954 college students aged 18-22 years from 9 universities in Shanghai, Hubei, and Jiangxi. Assessments were conducted using the International Physical Activity Questionnaire Short-Form (IPAQ-SF), Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder Scale-7 (GAD-7), and Pittsburgh Sleep Quality Index (PSQI) to evaluate physical activity, depressive and anxiety symptoms, and sleep quality, respectively. Logistic regression analysis was employed to explore the impact of sleep characteristics and physical activity patterns on depressive and anxiety symptoms and their comorbidity among college students. Results: The detection rates for depressive symptoms, anxiety symptoms, and comorbid depression and anxiety symptoms were 25.67%, 35.39%, and 23.15%, respectively. Factors such as gender, grade, household registration, parental education level, annual family income, family structure, and dietary habits were all associated with the detection rates of depressive and anxiety symptoms and their comorbidity (χ2=4.41-118.39, P<0.05). Physical activity patterns, sleep duration, sleep quality, and sleepwake characteristics were also associated with the occurrence of depressive and anxiety symptoms and their comorbidity (χ2=9.66-627.70, P<0.05). Logistic regression analysis showed that college students who stayed up late and slept less than 7 had the highest risk of depressive and anxiety symptoms and their comorbidity (OR=1.93, 1.85, 1.88, P<0.05). Compared to regular physical activity patterns, insufficient physical activity patterns were associated with an increased risk of depressive and anxiety symptoms (all OR=1.18, P<0.05). Further stratified analysis results showed that the risk of depression, anxiety and their comorbidity increased in college students who stayed up late and slept less than 7 h, went to bed before midnight and slept less than 7 h, or went to bed before midnight and slept more than 7 h but did not have sufficient physical activity (P<0.05). Conclusions Sleep characteristics and physical activity patterns significantly affect depressive and anxiety symptoms in college students. Universities should strengthen sleep management and implement flexible physical activity interventions to help students establish healthy lifestyles.

Three-dimensional poly (epsilon-caprolactone)/silk sericin (PCL/SS) porous nanofibrous scaffolds were prepared by electrospinning. The structure and properties of the scaffolds were characterized by Scanning Electron Microscope (SEM), Transmission Electron Microscope (TEM), Fourier Transform Infrared Spectroscopy (FTIR) and water contact angle instrument. Studies on cell adhension and proliferation were carried out by culturing human primary skin fibroblast cells (FEK4) on these scaffolds using SEM and MTS. The experimental results showed that the PCL/SS nanofibrous scaffolds with SS nanoparticles had porous non-woven mesh structure with nanofibrous cross-linked with each other. Fiber diameter was very uniform and precise, and the secondary structure of SS protein had not been changed. Furthermore, the capability of hydrophile increased with the SS addition, which improved FEK4 cells adhesion and proliferation on the scaffolds.

ObjectiveTo observe the effect of Feiyanning prescription （FYN） on cisplatin （DDP） resistance in non-small cell lung cancer （NSCLC） and explore the underlying mechanism. MethodCell counting kit-8 （CCK-8） assay was used to detect the proliferation of A549 and A549/DDP （DDP-resistant） cells treated by DDP （0， 2.0， 4.0， 6.0， 8.0， 10.0 mg⋅L^-1） and the proliferation of A549/DDP cells treated by FYN （0， 100， 200， 300， 400， 500， 600 mg⋅L^-1）. Based on immunofluorescence staining and Western blot （WB）， the expression of epithelial mesenchymal transition （EMT）-related proteins in A549 and A549/DDP groups was observed. A549/DDP cells were classified into control group， FYN group （200 mg⋅L^-1）， DDP group （6.0 mg⋅L^-1）， and combination group ［FYN （200 mg⋅L^-1） + DDP （6.0 mg⋅L^-1）］ and respectively treated with corresponding drugs. Then， invasion ability of each group was examined by transwell assay， and the expression of EMT-related proteins in each group by WB. Moreover， real-time fluorescence quantitative polymerase chain reaction（Real-time PCR） and immunofluorescence staining were separately applied to detect the mRNA and protein expression of drug resistance-related factors in each group， respectively. ResultCompared with A549 group， A549/DDP group showed high resistance to DDP （P<0.01）， low expression of E-cadherin， and high protein expression of Vimentin， N-cadherin， and Snail （P<0.05， P<0.01）. As compared with the control group， FYN inhibited the proliferation of A549/DDP cells in a concentration-dependent manner （P<0.01）， and the FYN group， DDP group， and combination group demonstrated low invasion ability （P<0.01）. In addition， the invasion ability in the combination group was particularly lower than that in the DDP group （P<0.01）. The expression of E-cadherin protein was higher and the protein expression of N-cadherin， Vimentin， and Snail was lower in the in FYN group than in the control group （P<0.01）. The protein expression of E-cadherin， N-cadherin， and Vimentin was lower and the expression of Snail was higher in the DDP group than in the control group （P<0.05，P<0.01）. The protein expression of E-cadherin， N-cadherin， Vimentin， and Snail in the combination group decreased as compared with that in the control group （P<0.01）. Compared with the DDP alone， the combination raised the expression of E-cadherin and lowered the protein expression of N-cadherin， Vimentin， and Snail （P<0.01）. The protein and mRNA expression of lung resistance-related protein （LRP） and multidrug resistance 1 （MDR1） was lower and the protein and mRNA expression of topoisomerase Ⅱα （TOPO Ⅱα） was higher in the FYN group than in the control group （P<0.01）. The protein and mRNA expression of LRP， MDR1， and TOPO Ⅱα was higher in the DDP group than in the control group （P<0.01）. The expression of LRP protein and mRNA showed no significant variation， but the protein and mRNA expression of MDR1 and TOPO Ⅱα increased in the combination group compared with those in the control group （P<0.01）. Compared with the DDP group， FYN group and combination group showed low protein and mRNA expression of LRP and MDR1 and high protein and mRNA expression of TOPO Ⅱα （P<0.01）. Compared with FYN， the combination elevated the protein and mRNA expression of LRP， MDR1， and TOPO Ⅱα （P<0.01）. ConclusionFYN prescription can reverse the DDP resistance of NSCLC by modulating EMT.

Chronic urticaria （CU） is a common skin disease worldwide， and its incidence is increasing year by year in various regions. Clinical manifestations such as severe itching can affect normal work， sleep， and daily life and increase the negative psychological burden caused by stress， anxiety， and depression. Mast cell activation and degranulation induced by immunoglobulin（Ig）E hypersensitivity is one of the core pathogenic mechanisms of CU， and there is no cure. Antihistamines such as cetirizine and loratadine are preferred for the clinical treatment of CU. Although they can effectively improve clinical manifestations such as itchiness， long-term application can increase the risk of adverse reactions and drug resistance. The phosphatidylinositol kinase/serine-threonine protein kinase B（PI3K/Akt） signaling pathway， as a classical signaling pathway regulated by phosphatidylinositol and tyrosine kinase receptor （RTK）， is a key target regulating the production and release of cytokines in macrophages and affecting the migration of leukocytes and the activation of mast cells and inflammation， and it can be involved in a variety of metabolic processes， such as mast cell activation and degranulation induced by IgE hypersensitivity and abnormal activation of the complement system so that the PI3K/Akt molecular pathway could be an important target for the future eradication of CU. However， the mechanism and potential role of the PI3K/Akt signaling pathway in the treatment of CU are less reported in China. Now， this paper reviewed the molecular mechanism of PI3K/Akt signaling pathway regulation in the treatment of CU and provided corroborative evidence and therapeutic strategy choices for the treatment of CU with traditional Chinese medicine （TCM） from the perspectives of molecular regulation and network pharmacology analysis.
