Hepatitis B virus （HBV） infection is a global public health issue， affecting the health of 250 million people worldwide. Despite the significant progress in antiviral therapy for HBV， some patients still experience low-level viremia （LLV） after receiving antiviral therapy and fail to achieve viral clearance， with an HBV DNA load remaining at a relatively low level of 20 — 2 000 IU/mL. LLV is often caused by multiple factors such as the high stability of the virus， the difficulty in clearing the virus with antiviral drugs， host immune factors， and drug resistance， which increase the difficulties in antiviral therapy. In addition， LLV can also cause liver damage， which may eventually progress to severe outcomes such as hepatocellular carcinoma. This article reviews LLV in hepatitis B in terms of diagnosis， influencing factors， clinical significance， and treatment strategies.

In this study， bibliometric methods were used to systematically investigate the name and origin， the evolution of prescription composition， dose evolution， origin and processing method， decoction method， ancient application， modified application， modern application and other information of Huoxiang Zhengqisan. After research， Huoxiang Zhengqisan， also known as Huoxiang Zhengqitang， was first recorded in Taiping Huimin Hejijufang. The original formula is composed of 41.3 g of Arecae Pericarpium， 41.3 g of Angelicae Dahuricae Radix， 41.3 g of Perilla frutescens（actually Perillae Folium）， 41.3 g of Poria， 82.6 g of Pinelliae Rhizoma， 82.6 g of Atractylodis Macrocephalae Rhizoma， 82.6 g of Citri Reticulatae Pericarpium（actually Citri Exocarpium Rubbum）， 82.6 g of Magnoliae Officinalis Cortex， 82.6 g of Platycodonis Radix， 123.9 g of Pogostemonis Herba， and 103.25 g of Glycyrrhizae Radix et Rhizoma. In this formula， Magnoliae Officinalis Cortex is processed according to the specifications for ginger-processed products， Glycyrrhizae Radix et Rhizoma is processed according to the specifications for stir-fried products， and other herbs are used in their raw products. The botanical sources of the herbs are consistent with the 2020 edition of Pharmacopoeia of the People's Republic of China. The above herbs are ground into a fine powder with a particle size passing through a No. 5 sieve. For each dose， take 8.26 g of the powdered formula， add 300 mL of water， along with 3 g of Zingiberis Rhizoma Recens and 3 g of Jujubae Fructus， and decoct until reduced to 140 mL. The decoction should be administered hot， with three times daily. To induce sweating， the patient should be kept warm under a quilt， and an additional dose should be prepared and taken if needed. This formula is traditionally used to relieve the exterior and resolve dampness， regulate Qi and harmonize the middle， which is mainly used to treat a series of diseases of digestive and respiratory systems. However， potential adverse reactions， including allergies， purpura and disulfiram-like reactions， should be considered during clinical use.

Postoperative pain seriously affects the recovery process of patients, resulting in prolonged hospital stay and increased care costs. Appropriate application of patient-controlled analgesia devices can effectively relieve perioperative acute pain. In 1994 patient-controlled analgesia began to be used in Peking Union Medical College Hospital, and the Acute Pain Service Working Group was established in 2004. With the cooperation of anesthesiologists and specialist nurses, the group jointly has implemented the whole process and standardized management based on patient-controlled analgesia, and constantly improved and innovated working methods, laying a solid foundation for the development of postoperative pain management. This paper systematically reviews and summarizes the work from the aspects of clinical focus, nursing management experience, promotion and dissemination of pain treatment concepts, and development of acute pain service model under the new situation, with the hope of providing valuable reference for comprehensively strengthening pain management in the process of diagnosis and treatment, and enhancing patients' satisfaction with perioperative analgesia services.

Objective:To explore the current situation and influencing factors of quality of life of septic patients in intensive care unit (ICU) after discharge, and to provide theoretical basis for clinical early psychological intervention and continuity of care.Methods:A prospective observational study was conducted. The septic patients who were hospitalized in the department of critical care medicine of the Affiliated Hospital of Jining Medical University and discharged with improvement from January 1 to December 31, 2022 were selected as the research objects. The demographic information, basic diseases, infection site, vital signs at ICU admission, severity scores of the condition within 24 hours after ICU admission, various biochemical indexes, treatment process, and prognostic indexes of all the patients were recorded. All patients were assessed by questionnaire at 3 months of discharge using the 36-item short-form health survey scale (SF-36 scale), the activities of daily living scale (ADL scale), and the Montreal cognitive assessment scale (MoCA scale). Multiple linear regression was used to analyze the factors influencing the quality of life of septic patients after discharge from the hospital.Results:A total of 200 septic patients were discharged with improvement and followed up at 3 months of discharge, of which 150 completed the questionnaire. Of the 150 patients, 57 had sepsis and 93 had septic shock. The total SF-36 scale score of septic patients at 3 months of discharge was 81.4±23.0, and the scores of dimensions were, in descending order, role-emotional (83.4±23.0), mental health (82.9±23.6), bodily pain (82.8±23.3), vitality (81.6±23.2), physical function (81.4±23.5), general health (81.1±23.3), role-physical (79.5±27.0), and social function (78.8±25.2). There was no statistically significant difference in the total SF-36 scale score between the patients with sepsis and septic shock (82.6±22.0 vs. 80.7±23.6, P > 0.05). Incorporating the statistically significant indicators from linear univariate analysis into multiple linear regression analysis, and the results showed that the factors influencing the quality of life of septic patients at 3 months after discharge included ADL scale score at 3 months after discharge [ β= 0.741, 95% confidence interval (95% CI) was 0.606 to 0.791, P < 0.001], length of ICU stay ( β= -0.209, 95% CI was -0.733 to -0.208, P = 0.001), duration of mechanical ventilation ( β= 0.147, 95% CI was 0.122 to 0.978, P = 0.012), total dosage of norepinephrine ( β= -0.111, 95% CI was -0.044 to -0.002, P = 0.028), mean arterial pressure (MAP) at ICU admission ( β= -0.102, 95% CI was -0.203 to -0.007, P = 0.036) and body weight ( β= 0.097, 95% CI was 0.005 to 0.345, P = 0.044). Conclusions:The quality of life of patients with sepsis at 3 months after discharge is at a moderately high level. The influencing factors of the quality of life of patients with sepsis at 3 months after discharge include the ADL scale score at 3 months after discharge, the length of ICU stay, the duration of mechanical ventilation, the total dosage of norepinephrine, MAP at ICU admission and body weight, and healthcare professionals should enhance the treatment and care of the patients during their hospitalization based on the above influencing factors, and pay attention to early psychological intervention and continued care for such patients.

Objective:To explore the influencing factors of intracranial hemorrhage in elderly patients with acute occlusion of intracranial arteries after treatment and reperfusion.Methods:A retrospective selection was conducted on elderly patients with acute occlusion of the intracranial artery who were treated at the Hebei Petro China Central Hospital from February 2019 to May 2021. Sixty patients who received mechanical thrombectomy treatment were selected as the observation group, and 60 patients who received combined arterial and venous thrombolysis treatment were selected as the control group. The vascular reperfusion rate and incidence of intracranial hemorrhage were observed and compared between the two groups. Meanwhile, multiple logistic regression analysis was used to identify the influencing factors of intracranial hemorrhage.Results:The reperfusion rate of the observation group′s blood vessels was 85.00%(51/60), significantly higher than the control group′s 68.33%(41/60), and the difference was statistically significant (χ 2=4.658, P=0.031). The National Institutes of Health Neurological Deficit Score (NIHSS) of the observation group after treatment was (10.57±2.23), significantly lower than that of the control group (14.73±2.84), and the difference was statistically significant ( P<0.05). The reperfusion rate of blood vessels in patients under 80 years old in the observation group was significantly higher than that in patients ≥80 years old ( P<0.05). The results of univariate analysis showed that there were statistically significant differences in age, NIHSS at admission, Alberta Stroke Program Early CT Score (ASPECTS), and neutrophil absolute value/lymphocyte ratio (NLR) between patients with and without intracranial hemorrhage (all P<0.05); Multivariate logistic regression analysis showed that age ( OR=1.756, 95% CI: 1.184-2.604) and NIHSS at admission ( OR=2.392, 95% CI: 1.401-4.084) were risk factors for postoperative intracranial hemorrhage in elderly patients with acute occlusion of the large intracranial artery, while ASPECTS ( OR=0.364, 95% CI: 0.190-0.697) was a protective factor. Conclusions:Mechanical thrombectomy has good clinical efficacy in the treatment of elderly patients with acute occlusion of intracranial arteries, and is worthy of clinical use; The intracranial hemorrhage after reperfusion is mainly influenced by the patient′s age, NIHSS at admission, and ASPECTS.

Objective To evaluate the effect of standardized lipid-lowering therapy in acute stroke patients via high-resolution magnetic resonance vessel wall imaging(HRMR-VWI)to follow-up the characteristics changes of intracranial atherosclerotic plaques.Methods Twenty-two acute stroke patients(65 plaques)were enrolled,and their clinical and imaging data were collected on admission and after standardized lipid-lowering therapy(355-370 days).Diffusion weighted imaging(DWI),three-dimensional time of flight magnetic resonance angiography(3D-TOF-MRA),and HRMR-VWI were performed in all patients.According to the changes in non-high density lipoprotein(non-HDL),all patients were divided into the effective lipid-lowering group and the ineffective lipid-lowering group.The demographic information,plaques characteristics and the effect of standardized lipid-lowering therapy of all patients were compared.Results One(2.33％)plaque in the effective group showed reverse remodeling and four(18.18％)new plaques in the anterior circulation in the ineffective group.Patients in the effective group were significantly better than those in the ineffective group in terms of plaque thickness,load,remodeling index(RI),and the rate of increase in plaque thickness,load,stenosis,and RI,with statistically significant difference(P＜0.05).There was no statistical significance in the rate of stenosis between the two groups.Conclusion Standardized lipid-lowering therapy has differences in the prognosis of acute stroke patients,and HRMR-VWI may be conducive to individualized assessment of the lipid-lowering effect.

Objective:To explore the chain mediating effect of basic activity of daily living and nutritional status the effects on comorbidity and frailty, so as to provide guidance for preventing and delaying the frailty of elderly patients with cardiovascular disease and abnormal glucose metabolism.Methods:The cross-sectional study method was adopted, 300 elderly patients with cardiovascular disease and abnormal glucose metabolism who were hospitalized in the cardiovascular medicine ward of Shandong Provincial Hospital Affiliated to Shandong First Medical University, were selected as the study objects from January to August 2022, and were surveyed using General Information Questionnaire, Frailty Scale, Charlson Comorbidity Index Scale, Barthel Index Rating Scale and Mini Nutritional Assessment-Short Form were used to investigate them.Results:A total of 300 questionnaires were collected and 291 valid questionnaires were returned. Out of 291 patients, 167 were male and 124 were female, with an age of (69.55 ± 7.01) years. Comorbidities in elderly patients with cardiovascular disease and abnormal glucose metabolism were positively correlated with frailty ( r=0.414, P<0.01), and negatively correlated with basic activity of daily living and nutritional status ( r=-0.399, -0.373, both P<0.01). Basic activity of daily living was positively correlated with nutritional status ( r=0.575, P<0.01) and negatively correlated with frailty ( r=-0.825, P<0.01). Nutritional status was negatively correlated with frailty ( r=-0.695, P<0.01). The chain mediating model showed that comorbidities had a significant direct effect on frailty (effect value of 0.102), basic activity of daily living partially mediated between comorbidity and frailty (effect value of 0.125). Basic activity of daily living and nutritional status partially chained between comorbidity and frailty (effect value of 0.036). Conclusions:The chain mediating roles of basic activity of daily living and nutritional status between comorbidity and frailty was established. Healthcare professionals should pay attention to the improvement of basic activity of daily living in elderly patients with cardiovascular diseases and abnormal glucose metabolism, guide them to have a reasonable diet to achieve balanced nutrition, and delay the onset and development of frailties.

Objective:Studying the effect of PRDX4 on esophageal squamous cell carcinoma cells(esophageal carcinoma,ESCC)proliferation and apoptosis as well as its potential mechanism.Methods:The University of Alabama at Birmingham cancer data analysis portal(UALCAN),gene expression profiling interactive analysis(GEPIA)and the Cancer Genome Atlas(TCGA)databases were used to predict PRDX4 expres-sion in ESCC and its relationship with pathological features and prognosis.The cancer and adjacent tissues of 60 patients with ESCC who un-derwent radical resection in the Affiliated Hospital of Weifang Medical College from August 2010 to August 2023 were selected as research samples.The expression level of PRDX4 in the patients was detected by immunohistochemistry(IHC).The extracted cancer and adjacent tis-sues were homogenized to analyze its mRNA expression.The expression levels of PRDX4 mRNA and related signaling proteins in ESCC cells were analyzed by real-time quantitative PCR and Western blot.Cell Counting Kit-8(CCK-8)assay and flow cytometry were used to analyze the effect of PRDX4 on cell proliferation and apoptosis.Finally,a subcutaneous tumor model in nude mice was constructed to validate the in vitro experimental results.Results:The data from the GEPIA and UALCAN showed that PRDX4 expression was abnormally increased and re-lated to the pathology stage,grade,and survival rate of patients.After knockdown and overexpression of PRDX4 in an ESCC cell line,the ex-pression of PRDX4,phos-phosphatidylinositol 3-kinase(p-PI3K),phos-protein kinase B(p-AKT),cyclinD1,and survivin protein decreased and increased,respectively;cell proliferation and apoptosis were positively regulated.Compared with the sh-NC group,tumor volume and weight in the sh-PRDX4 group were decreased.Conclusions:PRDX4 regulates the proliferation and apoptosis of ESCC cells by activating the PI3K/AKT signaling pathway.
