Objective To observe the clinical efficacy of withdrawal therapy based on regulating nutritive qi and defensive qi(shortened to Tiaohe Yingwei method)in treating sedative-hypnotic dependent insomnia of disharmony between nutritive qi and defensive qi type.Methods Ninety patients with sedative-hypnotic dependent insomnia of disharmony between nutritive qi and defensive qi type were randomly divided into the treatment group and the control group,with 45 patients in each group.The control group was given oral use of Estazolam by 25%of weekly dose-reduction,while the treatment group was treated with Chinese medicinal decoction of Tiaohe Yingwei Zhumian Prescription based on Tiaohe Yingwei method together with Estazolam.The treatment course for the two groups lasted for 4 weeks.The changes of Pittsburgh Sleep Quality Index(PSQI)scores,total TCM syndrome scores,and Drug-withdrawal Syndrome Scale(DWSS)scores in the two groups were observed before and after treatment.After treatment,the efficacy for improving sleep efficiency value(IUSEV)and clinical safety in the two groups were evaluated.Results(1)During the trial,2 cases fell off in the treatment group,and 43 cases included in the statistics;3 cases fell off in the control group,and 42 cases included in the statistics.(2)After 4 weeks of treatment,the total effective rate for improving IUSEV of the treatment group was 88.37%(38/43),and that of the control group was 61.90%(26/42).The intergroup comparison by non-parametric rank-sum test showed that the efficacy for improving IUSEV in the treatment group was significantly superior to that in the control group(P＜0.05).(3)After treatment,obvious reduction was shown in the overall PSQI scores and the scores of the items of sleep quality,time for falling asleep,sleep time,sleep efficiency,sleep disorder and daytime dysfunction in the two groups when compared with those before treatment(P＜0.05).The intergroup comparison showed that except for the items of sleep disorder and daytime dysfunction,the treatment group had stronger effect on decreasing the scores of the remaining items and the overall PSQI scores than the control group(P＜0.05).(4)After treatment,the total scores of TCM syndromes of both groups were significantly decreased compared with those before treatment(P＜0.05),and the decrease of the total scores of TCM syndrome in the treatment group was significantly superior to that in the control group(P＜0.05).(5)After treatment,the total DWSS scores of the two groups were significantly decreased compared with those before treatment(P＜0.05),and the effect on lowering the scores in the treatment group was significantly superior to that in the control group(P＜0.05).(6)During the course of treatment,no significant adverse reactions occurred in the two groups,or no abnormal changes were found in the safety indexes such as routine test of blood,urine and stool,liver and kidney function,and electrocardiogram of the patients.Conclusion Withdrawal therapy based on Tiaohe Yingwei method exerts certain effect for the treatment of sedative-hypnotic dependent insomnia of disharmony between nutritive qi and defensive qi type.The therapy is effective on improving the quality of sleep and reducing the incidence of drug-withdrawal syndrome,and has a high safety.

Purpose::Vibrio vulnificus ( V. Vulnificus) infection is characterized by rapid onset, aggressive progression, and challenging treatment. Bacterial resistance poses a significant challenge for clinical anti-infection treatment and is thus the subject of research. Enhancing host infection tolerance represents a novel infection prevention strategy to improve patient survival. Our team initially identified cytochrome P4501A1 (CYP1A1) as an important target owing to its negative modulation of the body's infection tolerance. This study explored the superior effects of the CYP1A1 inhibitor bergamottin compared to antibiotic combination therapy on the survival of mice infected with multidrug-resistant V. Vulnificus and the protection of their vital organs. Methods::An increasing concentration gradient method was used to induce multidrug-resistant V. Vulnificus development. We established a lethal infection model in C57BL/6J male mice and evaluated the effect of bergamottin on mouse survival. A mild infection model was established in C57BL/6J male mice, and the serum levels of creatinine, urea nitrogen, aspartate aminotransferase, and alanine aminotransferase were determined using enzyme-linked immunosorbent assay to evaluate the effect of bergamottin on liver and kidney function. The morphological changes induced in the presence of bergamottin in mouse organs were evaluated by hematoxylin and eosin staining of liver and kidney tissues. The bacterial growth curve and organ load determination were used to evaluate whether bergamottin has a direct antibacterial effect on multidrug-resistant V. Vulnificus. Quantification of inflammatory factors in serum by enzyme-linked immunosorbent assay and the expression levels of inflammatory factors in liver and kidney tissues by real-time quantitative polymerase chain reaction were performed to evaluate the effect of bergamottin on inflammatory factor levels. Western blot analysis of IκBα, phosphorylated IκBα, p65, and phosphorylated p65 protein expression in liver and kidney tissues and in human hepatocellular carcinomas-2 and human kidney-2 cell lines was used to evaluate the effect of bergamottin on the nuclear factor kappa-B signaling pathway. One-way ANOVA and Kaplan-Meier analysis were used for statistical analysis. Results::In mice infected with multidrug-resistant V. Vulnificus, bergamottin prolonged survival ( p = 0.014), reduced the serum creatinine ( p = 0.002), urea nitrogen ( p = 0.030), aspartate aminotransferase ( p = 0.029), and alanine aminotransferase ( p = 0.003) levels, and protected the cellular morphology of liver and kidney tissues. Bergamottin inhibited interleukin (IL)-1β, IL-6, and tumor necrosis factor (TNF)-α expression in serum (IL-1β: p = 0.010, IL-6: p = 0.029, TNF-α: p = 0.025) and inhibited the protein expression of the inflammatory factors IL-1β, IL-6, TNF-α in liver (IL-1β: p = 0.010, IL-6: p = 0.011, TNF-α: p = 0.037) and kidney (IL-1β: p = 0.016, IL-6: p = 0.011, TNF-α: p = 0.008) tissues. Bergamottin did not affect the proliferation of multidrug-resistant V. Vulnificus or the bacterial load in the mouse peritoneal lavage fluid ( p = 0.225), liver ( p = 0.186), or kidney ( p = 0.637). Conclusion::Bergamottin enhances the tolerance of mice to multidrug-resistant V. Vulnificus infection. This study can serve as a reference and guide the development of novel clinical treatment strategies for V. Vulnificus.

Objective To investigate the infiltration of peripheral monocyte in the hippocampal CA3 area in neuralgia mice at different time points and explore the effects of the infiltration on neuralgia and the neuralgia-induced anxiety-like behavior in mice.Methods The healthy male C57 mice were randomly divided into four groups:sham,sciatic nerve branch selective injury(SNI)model(SNI),CCR2 inhibitor RS102895(SNI+RS102895)and microglial inhibitor minocycline(MC)(SNI+MC)groups.Both the sham and SNI groups were further divided into 7 days,14 days and 18 days groups,and the SNI+RS102895 and SNI+MC groups were sampled on the 18th day.Neuralgia was induced by SNI,and mechanical hyperalgesia was assessed by paw withdrawal threshold(PWTs)at different time points.Elevated plus maze(EPM)and open field test(OFT)were performed respectively two days and one day before sacrifice.Immunofluorescence was used to observe the expressions of leukocyte differentiation antigen 45(CD45)and the co-expression with microglial markers ionized calcium binding adaptor molecule-1(IBA-1),transmembrane protein 119(TMEM119),astrocyte marker glial fibrillary acidic protein(GFAP),and neuronal marker neuronal nuclei(NeuN)in the hippocampal CA3.The percentage of monocytes in the whole brain of 14 days SNI mice was determined by flow cytometry.Minocycline at 90 mg/(kg·d),RS 102895 at 5 mg/(kg·d)and saline were administered orally on the 5th to 16th day in the corresponding 18 days groups,and the effects of blocking monocyte infiltration on neuralgia and anxiety-like behavior and the expressions of CD45 and 1BA-1 in CA3 region of hippocampus were observed.Results On the first day after SNI,the PWTs of mice in the 7 days and 14 days groups decreased and continued until before sacrifice(P＜0.01).The CD45 expression did little in the 7 days sham group.Compared with the sham group at the same time point,the CD45 expression did not increase in 7 days SNI mice((P＞0.05)and increased significantly in 14 days SNI mice(P＜0.01),only slightly co-expressed with IBA-1 and TMEM119 and no co-expression with GFAP and NeuN,the percentage of monocytes in the whole brain increased significantly in 14 days SNI mice(P＜0.01).Inhibition of microglial activation or CCR2 expression reduced the expression of CD45 in the CA3 in SNI mice(P＜0.01),increased the PWTs(P＜0.01)and alleviated anxiety-like behavior in SNI mice(P＜0.01).Conclusion There was an infiltration of peripheral monocytes in the hippocampal CA3 region after 14 days of SNI-induced neuralgia,which might be involved in the maintenance of neuralgia and the development of neuralgia-induced anxiety-like behaviors.

Objective With the widespread of transcatheter aortic valve replacement(TAVR)in patients with severe symptomatic aortic stenosis(AS),the life-cycle management has become a major determinant of prognosis.Methods A total of 408 AS patients who underwent successfully TAVR from June 2021 to August 2023 were consecutively enrolled in Hospital Valve Intervention Center.Patients were assigned to the Usual Care(UC)group between June 2021 and October 2022,while patients were assigned to the Heart Multi-parameter Monitoring(HMM)group between November 2022 and August 2023.The primary endpoint was defined as composite endpoint within 6 months post-TAVR,including all-cause death,cardiovascular death,stroke/transient ischemic attack,conduction block,myocardial infarction,heart failure rehospitalization,and major bleeding events.Secondary endpoints were the time interval(in hours)from event occurrence to medical consultation or advice and patient satisfaction.Statistical analysis was performed using Kaplan-Meier and multivariable Cox proportional hazards models.Results The incidence of primary endpoint in HMM group was significantly lower than that in UC group(8.9％vs.17.7％,P=0.016),the driving event was the rate of diagnosis and recognition of conduction block.The average time intervals from event occurrence to receiving medical advice were 3.02 h in HHM group vs.97.09 h in UC group(P＜0.001).Using cardiac monitoring devices and smart healthcare platforms provided significant improving in patients long-term management(HR 0.439,95％CI 0.244-0.790,P=0.006).Conclusions The utilization of cardiac monitoring devices and smart healthcare platforms effectively alerted clinical events and improved postoperative quality of life during long-term management post TAVR.

Background: and Purpose Intravenous tenecteplase (TNK) efficacy has not been well demonstrated in acute ischemic stroke (AIS) beyond 4.5 hours after onset. This study aimed to determine the effect of intravenous TNK for AIS within 4.5 to 24 hours of onset. Methods: In this pilot trial, eligible AIS patients with diffusion-weighted imaging (DWI)-fluid attenuated inversion recovery (FLAIR) mismatch were randomly allocated to intravenous TNK (0.25 mg/kg) or standard care within 4.5–24 hours of onset. The primary endpoint was excellent functional outcome at 90 days (modified Rankin Scale [mRS] score of 0–1). The primary safety endpoint was symptomatic intracranial hemorrhage (sICH). Results: Of the randomly assigned 80 patients, the primary endpoint occurred in 52.5% (21/40) of TNK group and 50.0% (20/40) of control group, with no significant difference (unadjusted odds ratio, 1.11; 95% confidence interval 0.46–2.66; P=0.82). More early neurological improvement occurred in TNK group than in control group (11 vs. 3, P=0.03), but no significant differences were found in other secondary endpoints, such as mRS 0–2 at 90 days, shift analysis of mRS at 90 days, and change in National Institutes of Health Stroke Scale score at 24 hours and 7 days. There were no cases of sICH in this trial; however, asymptomatic intracranial hemorrhage occurred in 3 of the 40 patients (7.5%) in the TNK group. Conclusion This phase 2, randomized, multicenter study suggests that intravenous TNK within 4.5–24 hours of onset may be safe and feasible in AIS patients with a DWI-FLAIR mismatch.

Objective    To summarize the experience of robot-assisted lung basal segmentectomy, and analyze the clinical application value of intersegmental tunneling and pulmonary ligament approach for S9 and/or S10 segmentectomy. Methods    The clinical data of 78 patients who underwent robotic lung basal segmentectomy in our hospital between January 2020 to May 2022 were retrospectively reviewed. There were 32 males and 46 females with a median age of 50 (33-72) years. The patients who underwent S9 and/or S10 segmentectomy were divided into a single-direction group (pulmonary ligament approach, n=19) and a bi-direction group (intersegmental tunneling, n=19) according to different approaches, and the perioperative outcomes between the two groups were compared. Results    All patients successfully completed the operation, without conversion to thoracotomy and lobectomy, serious complications, or perioperative death. The median operation time was 100 (40-185) min, the blood loss was 50 (10-210) mL, and the median number of dissected lymph nodes was 3 (1-14). There were 4 (5.1%) patients with postoperative air leakage, and 4 (5.1%) patients with hydropneumothorax. No patient showed localized atelectasis or lung congestion at 6 months after the operation. Further analysis showed that there was no significant difference in the operation time, blood loss, thoracic drainage time, complications or postoperative hospital stay between the single-direction and bi-direction groups (P>0.05). However, the number of dissected lymph nodes of the bi-direction group was more than that of the single-direction group [6 (1-13) vs. 5 (1-9), P=0.040]. Conclusion    The robotic lung basal segmentectomy for pulmonary nodules is safe and effective. The  perioperative results of robotic S9 and/or S10 complex segmentectomy using intersegmental tunneling and pulmonary ligament approach are similar.

Objective:To investigate the factors affecting the accuracy of electronic portal imaging device (EPID)-based in vivo dose verification in radiotherapy for patients with lung and esophageal cancers, and to recommend the workflow and specifications for the application of the in vivo dose verification. Methods:This study randomly selected 32 patients who received radiotherapy for esophageal and lung cancers at the Department of Radiation Oncology, Jinhua Municipal Central Hospital from May to August 2022, including 14 lung cancer cases and 18 esophageal cancer cases. Using a uRT-linac 506c linear accelerator, these patients were treated according to the dynamic intensity-modulated radiotherapy (dIMRT) and EPID-based In vivo dose verification ( In vivo EPID) plans developed with the uRT-TPOIS planning system. The In vivo dose verification performed during the treatment included 238 fractions of In vivo EPID and 80 fractions of image-guided radiotherapy (IGRT) for the lung cancer cases, as well as 414 fractions of In vivo EPID and 105 fractions of IGRT for the esophageal cancer cases. The 2D γ passing rate for each irradiation field was obtained according to the set threshold value. Furthermore, fractioned irradiation fields with γ-passing rates below the threshold value were analyzed, and primary factors decreasing the γ-passing rate were further analyzed by combining the online CT images and 3D reconstruction-derived dose. Results:For lung and esophageal cancers, the mean γ-passing rates were 95.1% ± 5.7% and 96.5% ± 4.5%, respectively at 3 mm/5%; 91.5% ± 8.4% and 92.2% ± 4.9%, respectively at 3 mm/3%, and 79.1% ± 14.7% and 83.7% ± 8.2%, respectively at 2 mm/2%, indicating no statistically significant differences between two cancers ( P > 0.05). The average γ passing rate for beam orientations near 0°/180° (Group A) was higher than those near 90°/270° (Group B) 3 mm/5%: Z = -25.4, P < 0.05; 3 mm/3%: Z = -26.8, P < 0.05). The IGRT correction of setup errors significantly improved the γ passing rates (96.3% ± 5.1% and 96.4% ± 4.9%, respectively at 3 mm/5%, Z = -5.50, P < 0.05; 92.3% ± 8.0% and 91.3% ± 7.7%, respectively at 3 mm/3%, Z = -9.54, P < 0.05). The results of In vivo dose verification were affected by changes in the volumes and motion of tumors and normal tissues, radiotherapy positioning, and adequacy of pre-treatment preparation. Conclusions:EPID-based In vivo dose verification during radiotherapy can avoid incorrect irradiation. However, it is necessary to standardize the workflow of the EPID-based In vivo dose verification to avoid the decrease in the γ passing rate caused by artificial factors.

COVID-19 has been prevalent for three years. The virulence of SARS-CoV-2 is weaken as it mutates continuously. However, elderly patients, especially those with underlying diseases, are still at high risk of developing severe infections. With the continuous study of the molecular structure and pathogenic mechanism of SARS-CoV-2, antiviral drugs for COVID-19 have been successively marketed, and these anti-SARS-CoV-2 drugs can effectively reduce the severe rate and mortality of elderly patients. This article reviews the mechanism, clinical medication regimens, drug interactions and adverse reactions of five small molecule antiviral drugs currently approved for marketing in China, so as to provide advice for the clinical rational use of anti-SARS-CoV-2 in the elderly.

Background In mainland China, patients with neovascular age-related macular degeneration (nAMD) have approximately an 40% prevalence of polypoidal choroidal vasculopathy (PCV). This disease leads to recurrent retinal pigment epithelium detachment (PED), extensive subretinal or vitreous hemorrhages, and severe vision loss. China has introduced various treatment modalities in the past years and gained comprehensive experience in treating PCV.Methods A total of 14 retinal specialists nationwide with expertise in PCV were empaneled to prioritize six questions and address their corresponding outcomes, regarding opinions on inactive PCV, choices of anti-vascular endothelial growth factor (anti-VEGF) monotherapy, photodynamic therapy (PDT) monotherapy or combined therapy, patients with persistent subretinal fluid (SRF) or intraretinal fluid (IRF) after loading dose anti-VEGF, and patients with massive subretinal hemorrhage. An evidence synthesis team conducted systematic reviews, which informed the recommendations that address these questions. This guideline used the GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) approach to assess the certainty of evidence and grade the strengths of recommendations. Results The panel proposed the following six conditional recommendations regarding treatment choices. (1) For patients with inactive PCV, we suggest observation over treatment. (2) For treatment-na?ve PCV patients, we suggest either anti-VEGF monotherapy or combined anti-VEGF and PDT rather than PDT monotherapy. (3) For patients with PCV who plan to initiate combined anti-VEGF and PDT treatment, we suggest later/rescue PDT over initiate PDT. (4) For PCV patients who plan to initiate anti-VEGF monotherapy, we suggest the treat and extend (T&E) regimen rather than the pro re nata (PRN) regimen following three monthly loading doses. (5) For patients with persistent SRF or IRF on optical coherence tomography (OCT) after three monthly anti-VEGF treatments, we suggest proceeding with anti-VEGF treatment rather than observation. (6) For PCV patients with massive subretinal hemorrhage (equal to or more than four optic disc areas) involving the central macula, we suggest surgery (vitrectomy in combination with tissue-plasminogen activator (tPA) intraocular injection and gas tamponade) rather than anti-VEGF monotherapy. Conclusions Six evidence-based recommendations support optimal care for PCV patients' management.

Background In the context of improving urban environment for healthy aging, it is necessary to rationally plan and provide community living space and public service facilities suitable for the elderly, and constantly optimize the built environment towards an age-friendly city. Objective To understand the relationship between community built environment and obesity in the elderly in Longgang City, and to provide a reference basis for improving the health of the elderly. Methods Elderly adults aged 60-90 years (n=6527) who completed a physical examination during the period from October 2020 to January 2021 in Longgang City were surveyed, and data on height and weight, waist circumference (WC), and other sociological demographic characteristics were obtained. Overweight was determined by 24 kg·m⁻² ≤ body mass index (BMI) < 28 kg·m⁻² and obesity by BMI ≥ 28 kg·m⁻². Men with WC ≥ 85 cm and women with WC ≥ 80 cm were considered central obesity. Based on the participants' residential addresses, geocoding was performed using a geographic information system, and built environment indicators such as restaurants, convenience stores, and basic medical facilities were obtained using Gaode Map. A binary logistic regression model with adjusted individual-level covariates was used to evaluate the relationship between obesity and built environment indicators among elderly adults by gender and age. Results Among the 6527 community elderly, 46.93% were male and 53.07% were female, with a mean age of (73.69±0.07) years, a mean BMI of (24.32±2.84) kg·m⁻², and 51.92% of the elderly were overweight or obese. The regression results showed that for elderly men, the more convenience stores and the higher mixed land use in residential areas, the higher risk of central obesity; however, the increases in street connectivity and accessibility to parks and recreational areas were associated a decreased risk of central obesity. The prevalence of overweight/obesity was higher among elderly women with more convenience stores in residential areas, while increased street connectivity was associated with a lower prevalence of central obesity among elderly women. Accessibility to primary health care facilities was negatively associated with the risk of central obesity among the 60- to 70-year-olds. For elderly residents aged 71−80 years, higher mixed land use and better accessibility to transit stations were associated with a higher prevalence of overweight/obesity, while street connectivity was negatively associated with the central obesity. Proximity to parks and recreational areas was associated with a reduced risk of overweight/obesity among the 81- to 90-year-olds. Conclusion Among the variables of a 500-m neighborhood built environment, the number of convenience stores, mixed land use, street connectivity, accessibility to primary health care facilities, accessibility to public transit stations, and accessibility to parks and recreational areas are correlated with obesity among elderly residents, and the degree of influence varies by gender and age.
