OBJECTIVE To investigate the actual construction and operation status of established and under-construction centralized （cloud） prescription review centers （shortened for “prescription review center”） of close-knit county-level medical consortium in a certain city， so as to provide reference for improving the construction quality of the prescription review center. METHODS An online questionnaire survey was conducted to collect the data from 51 established and under-construction prescription review center in the city， covering basic information， funding sources， talent management， system construction， review rule maintenance， prescription review practices， prescription evaluation， data utilization， and current challenges. The collected data were summarized and analyzed. RESULTS A total of 51 valid questionnaires were retrieved， covering 32 established and 19 under-construction prescription review center. Among the 32 established prescription review centers， the main funding sources for their construction came from government financial allocations， accounting for 56.25%. Only 25.00% of prescription review center had review pharmacists who fully met national qualification requirements， and just 55.00% updated more than 10 review rule entries per month on average. Outpatient prescription verification realized full coverage， but 37.50% of prescription review centers only supported rationality verification of single prescriptions， and 50.00% could not retrieve laboratory and examination results to assist in prescription review. Additionally， 40.62% of prescription review center had not regularly conducted prescription evaluations for primary care institutions. The data from prescription review center was mainly used to support medication monitoring. Among the 19 prescription review centers currently in the planning stage， 63.16% had no identified funding sources. CONCLUSIONS The operation and construction of prescription review center in the city face challenges， such as funding shortages， absence of collaborative incentive mechanisms， and insufficient manpower.It is suggested that the state should issue a unified standard for the construction of the prescription review center as soon as possible， and local health administrative departments should formulate supporting policies and clarify assessment indicators in combination with the actual situation of the region.

ObjectiveTo analyze the characteristics of 150 patients with spinal cord injury complicated with spasticity. MethodsA cross-sectional survey was conducted on 150 patients with spinal cord injury accompanied by spasticity from September, 2019 to December, 2024. Their age, gender, cause of injury, injury site, severity of injury, spasticity severity and other indicators were recorded. The relationships between different characteristics were analyzed, and a correlation analysis of disease duration, spasticity grade, injury level, injury severity and age were conducted. ResultsThere was no significant difference in age distribution between patients with tetraplegia and paraplegia (Z = 0.806, P = 0.420). The proportions of trauma (χ² = 3.982, P = 0.046) and tetraplegia (χ² = 10.559, P = 0.010) were higher in males than in females. Trauma was the main cause of injury in both tetraplegia and paraplegia patients; the proportion of tetraplegia was higher than paraplegia in trauma patients, while paraplegia was higher than tetraplegia in non-trauma patients (χ² = 11.885, P < 0.001). Patients with tetraplegia was dominated by incomplete injury, whereas patients with paraplegia was dominated by complete injury (χ² = 10.885, P = 0.012). Grade A injury was predominant in trauma patients (P = 0.003). Spasticity grade showed a very weak positive correlation with disease duration (r = 0.175, P = 0.032) and age (r = 0.168, P = 0.040). Injury severity showed a very weak positive correlation with age (r = 0.183, P = 0.025). ConclusionCharacteristics of patients with spinal cord injury complicated with spasticity is different with gender, cause of injury, injury level, injury severity.

Objective To investigate the protective effect and underlying mechanisms of HydroMg, a novel sustained-release hydrogen donor, in a model of doxorubicin (DOX)-induced chronic cardiotoxicity. Methods H9C2 cells were treated with 1 μmol/L DOX and/or 1 μg/mL HydroMg, and mitochondrial membrane potential, reactive oxygen species (ROS) levels, and apoptosis were measured. In the animal experiment, mice were divided into control, HydroMg, DOX, and DOX＋HydroMg groups. The HydroMg group received intraperitoneal injection of HydroMg (100 mg/kg). Chronic cardiotoxicity was established by intraperitoneal injection of DOX (5 mg/kg every week) for four consecutive weeks; In the DOX＋HydroMg group, HydroMg (100 mg/kg) was administered intraperitoneally 4–5 h prior to each DOX injection. Cardiac function and remodeling were evaluated by echocardiography and heart weight index (HWI). The long-term survival of mice were analyzed. Subsequently, transcriptome sequencing was performed on myocardial tissues from the DOX group to identify key molecular alterations compared with controls. Results At the cellular level, HydroMg treatment effectively reversed DOX-induced mitochondrial dysfunction and oxidative stress, as evidenced by restored membrane potential, reductions in total ROS and mitochondrial superoxide levels by approximately 30% and 9%, respectively, and a decrease in the apoptosis rate from 34.13% to 18.27%. In the animal model, compared with the DOX group, HydroMg intervention increased left ventricular ejection fraction (LVEF) and fractional shortening (LVFS) by 9.62% and 5.82%, respectively, attenuated the reduction in HWI (4.41 mg/mm vs 3.53 mg/mm), and improved the 4-week survival rate (80% vs 60%). Transcriptomic analysis revealed that the core molecular features of DOX-induced cardiotoxicity, including widespread suppression of oxidative phosphorylation and antioxidant pathways. Conclusions HydroMg protects against DOX-induced chronic cardiotoxicity by alleviating oxidative stress and improving mitochondrial function, and provides a potential therapeutic strategy against DOX-related cardiotoxicity.

Objectives:QT interval prolongation during treadmill test exercise is one of the clinical feature of patients with long QT syndrome(LQTS).This study aimed to explore the feasibility and efficacy of treadmill exercise testing as an auxiliary diagnosis tool for LQTS in clinical practice.Methods:We enrolled normal healthy individuals,common cardiovascular disease patients,and clinically diagnosed or suspected LQTS patients,who underwent treadmill exercise test from July 2023 to July 2024 at Fuwai Hospital.A special treadmill exercise testing procedure was designed to record the QT interval correction(QTc)intervals of the twelve lead electrocardiogram at 6 time points when performing the exercise tablet,including supine,sitting,standing,peak exercise,and recovery at 1-minute and 4-minute.The differences in QTc intervals among healthy group,cardiovascular diseases group,and suspected LQTS group were compared.Results:A total of 80 cases were consecutively enrolled,including 37 normal healthy controls,25 patients with common cardiovascular disease,and 18 patients with suspected LQTS.The QTc intervals at 6 points did not differ significantly between normal healthy controls and patients with cardiovascular disease,with QTc intervals less than 480 ms at all measurement.For patients with suspected LQTS,67.7%(12/18)of these patients presented a QTc interval≥480 ms at the 4-minute during recovery period.Among them,5 cases were confirmed to have pathogenic gene mutations of LQTS by genetic testing(including 1 case with a lying electrocardiogram QTc interval of 489 ms diagnosed with LQTS 1 type and a QTc interval of 636 ms during the 4-minute recovery period after exercise);5 clinically diagnosed patients(negative or undetectable in genetic testing)with a Schwartz score≥4,and the remaining 2 patients had a Schwartz score of 3.The remaining 5/18 patients,include 2 patients with clinical Schwartz scores≥4 and 3 patients with clinical suspicion(Schwartz scores 2-3)had a 4 min QTc interval of 445-480 ms during exercise recovery.Another patient with clinical suspicion(Schwartz score 3)had a 4 min QTc interval of<445 ms during exercise recovery and a negative genetic test at a later stage.Receiver operating characteristic curve analysis showed a sensitivity of 83.3%and specificity of 98.4%for QTc interval≥482 ms during the 4-minute recovery period of exercise as the LQTS diagnostic cutoff.Conclusions:This study results suggest that this special treadmill exercise testing protocol is effective in identifying LQTS and has strong feasibility and generalizability for clinical practice.

Objective:To understand spatial aggregation of lung cancer mortality and its changing trends over the past fifty years in different counties and districts of Shandong Province from 1970 to 2021.Methods:The mortality data of lung cancer were obtained from the death registration system of Shandong province and three retrospective surveys of death cause. The mortality rate and age-standardized mortality rate were used to describe the changing trend of lung cancer in different years, and the contribution value of population factors and non-population factors in lung cancer mortality change was calculated by the mortality differential decomposition method. GeoDa 1.20 and ArcGIS 10.8 software were used for spatial autocorrelation analysis and visualization map display.Results:The crude mortality rate of lung cancer in Shandong Province showed a significant upward trend from 1970 to 2021, rising from 7.22 per 100 000 in 1970-1974 to 62.73 per 100 000 in 2020-2021, with an increase of 7.69 times. Meanwhile, the standardized mortality rate of lung cancer exhibited a trend of increasing first and then decreasing. The differential analysis of lung cancer mortality in different years revealed that changes in crude mortality rates were the result of the combined effects of demographic and non-demographic factors. The proportion of population factors (aging population) leading to an increase in lung cancer mortality rate rose from 2.12% in 1990-1992 to 40.20% in 2020-2021. From a spatial distribution perspective, there were significant regional differences in lung cancer mortality rates among counties (cities, districts) in Shandong Province across different eras. Compared to the period of 1970-1974, the lung cancer mortality rates in all counties and districts in 2020-2021 showed a considerable increase, and there were noticeable changes in the areas of high-high and low-low clustering of lung cancer mortality rates across different eras.Conclusion:There have been significant temporal and spatial changes in the mortality rate of lung cancer in Shandong Province from 1970 to 2021. The crude mortality rate has shown an upward trend, while the standardized mortality rate increases first and then decreases. The concentration of lung cancer mortality rates in counties and districts has also undergone significant changes.

Objective:To describe the distribution characteristics and trends of mortality and spatial aggregation of esophageal cancer in Shandong Province from 1970 to 2021.Methods:The mortality data of esophageal cancer were obtained from the death registration system of Shandong Province and three national all-cause mortality retrospective surveys. The crude mortality rate (CMR) and age-standardized mortality rate (ASMR, the Segi′s world standard population) were used to describe the mortality of esophageal cancer. Mortality differential decomposition was applied to quantify the contributions of demographic and non-demographic factors. The death levels of esophageal cancer in different counties (cities and districts) in Shandong Province from 1970 to 1974 and 2020 to 2021 were visualized by the ArcGIS 10.8 software, and global and local autocorrelation analyses were conducted by using the GeoDa 1.12 software.Results:The CMR of esophageal cancer in Shandong Province increased first and then decreased from 1970 to 2021. The CMR of esophageal cancer decreased from 17.59/100 000 in the period of 1970—1974 to 14.32/100 000 in the period of 2020—2021. The ASMR of esophageal cancer decreased from 20.04/100 000 in the period of 1970—1974 to 6.53/100 000 in the period of 2020—2021. Compared with the period of 1970—1974, both demographic and non-demographic factors contributed to the increase in esophageal cancer mortality rate from 1990 to 1992. However, demographic factors continued to contribute to the increase in esophageal cancer mortality rate from 2004 to 2005, 2011 to 2013, and 2020 to 2021, while non-demographic factors contributed to the continuous decrease in esophageal cancer mortality rate. The global autocorrelation analysis results showed that the Moran′s I index of ASMR of esophageal cancer in each county (city, district) of Shandong Province from 1970 to 1974 and from 2020 to 2021 were 0.67 and 0.57, respectively. Local autocorrelation analysis showed that there were 19 and 13 areas of high-high clustering of esophageal cancer in the periods of 1970—1974 and 2020—2021, respectively, with 12 overlapping counties (cities, districts). Conclusion:From 1970 to 2021, the CMR of esophageal cancer increases first and then decreases, while the ASMR of esophageal cancer gradually decreases in Shandong Province. The distribution of esophageal cancer mortality has significant spatial aggregation and changes over time.

ObjectiveTo investigate the reversal effect of Cordyceps sinensis extract on immunotherapy resistance of non-small cell lung cancer （NSCLC）. MethodsELISA， flow cytometry， and co-culture assays were performed to evaluate the effects of Cordyceps sinensis extract on cytokine secretion， proliferation， and tumor cell killing activity of Jurkat （JKT） cells. Furthermore， the therapeutic effect of Cordyceps sinensis extract on programmed cell death ligand 1 （PD-L1） resistant lung cancer was evaluated through in vivo experiments both alone and in combination with anti-PD-L1 monoclonal antibody. ResultsCordyceps sinensis extract enhanced the secretion of cytokines interferon gamma（IFN-γ）， tumor necrosis factor-alpha（TNF-α） and interleukin-2 （IL-2）in JKT cells， promoted cell proliferation （P=0.006）， and boosted their killing function against tumors （P＜0.001）. Compared with the control group， in vivo study demonstrated that Cordyceps sinensis extract monotherapy effectively inhibited the growth of PD-L1-resistant tumors ［tumor growth inhibition value （TGI）=26.1%， P=0.090］， while its combination with anti-PD-L1 antibody significantly reversed PD-L1 resistance （TGI=50.6%， P＜0.001）. ConclusionThis study provides certain data support for the activation of anti-tumor immunity by Cordyceps sinensis extract， and offers a new treatment strategy for enhancing anti-tumor immunity and reversing immune resistance in lung cancer.

Objective:To establish an evaluation index system for patient safety education targeted at undergraduate nursing interns.Methods:Based on the CIPP (Context, Input, Process, Product) evaluation model, a preliminary draft of the index system was developed using a literature review and semi-structured interviews. The Delphi method and the Analytic Hierarchy Process were applied to finalize the index system.Results:Two rounds of Delphi expert consultation were conducted. In the first round, 23 questionnaires were distributed, and 20 valid responses were received (effective response rate: 86.96%) . Among them, 15 experts (75.00%) provided revision suggestions. In the second round, 20 questionnaires were distributed, and 19 valid responses were received (effective response rate: 95.00%) , with two experts (10.53%) offering suggestions. The expert authority coefficients for the two rounds were 0.900 and 0.921, respectively. Kendall's coordination coefficients were 0.272 and 0.273 ( P<0.01) . The final evaluation system consisted of four first-level indicators, eight second-level indicators, and 18 third-level indicators. Conclusions:The evaluation index system constructed in this study is scientifically grounded and reliable. However, its practical utility and applicability require further validation.

Objective:To explore the application value of right-opening single flap valvuloplasty based on tubular stomach in gastrointestinal reconstruction after laparoscopic proximal gastrectomy.Method:Use a linear cutting stapler to make a parallel curve from the angle of the stomach to the junction of the gastric fundus to remove the lesser curvature of the stomach, and detach the gastric body about 5 cm away from the tumor to create a tubular stomach. Use a marker pen to draw a C-shaped seromuscular flap area with a width of 2.5 cm and a height of 3.5 cm 1.5 cm below the residual stomach closure nail, and create a free muscle flap in the gap between the plasma muscle layer and the submucosal layer. Make a transverse incision of 3 cm at the lower edge of the mucosal bed, and intermittently suture the entire lower edge of the gastric wall with 3 stitches. Under laparoscopy, use 4-0 barbed wire to suture the 1 cm wide muscular layer at the top of the tubular stomach and the posterior wall of the esophagus about 5 cm away from the esophageal stump with 3 stitches. Push the upper end of the tubular stomach into the mediastinum, and then tighten the barbed wire to ensure a tight fit between the stomach and the posterior wall of the esophagus. Use an ultrasonic scalpel to remove the esophageal stump, suture the entire posterior wall of the esophagus with the gastric mucosa, and use barbed wire to suture the anterior wall from left to right. The anastomotic site is completely covered with a free muscle flap, and the barbed line is used to continuously suture the muscle flap along the C-shaped line to the gastric pulp muscle layer at the edge of the mucosal bed, embedding the anastomotic site and completing the reconstruction of the digestive tract.Results:Clinical data of 23 patients (18 from the First Affiliated Hospital of Wenzhou Medical University and 5 from the Quzhou Hospital affiliated with Wenzhou Medical University) who underwent laparoscopic proximal gastrectomy, tubular gastroesophageal anastomosis, and pure manual right flap reconstruction surgery for esophagogastric junction adenocarcinoma and proximal gastric cancer from October 2023 to August 2024. There were 15 males and 8 females, with an age of (65.3±7.7) years, the BMI was (22.9±2.8) kg/m 2. All patients in the group successfully completed the surgery, with a surgery time of (218.5±38.1) minutes, including (73.5±19.2) minutes for anastomosis, intraoperative blood loss of (64.5±15.4) ml, postoperative passage of gas on (3.4±0.5) days, first consumption of liquid food after surgery of (3.9±1.1) days, and postoperative hospital stay of (9.1±0.8) days. One patient developed anastomotic stenosis (grade I) after surgery, presenting with mild swallowing obstruction, which returned to normal after dietary adjustment, and there were no cases of secondary surgery. The median follow-up time for the entire group was 4.0 (0.7-7.0) months, during which there were no deaths or tumor recurrence or metastasis, no complications such as anastomotic stenosis or gastric emptying disorders, and no complaints of acid reflux or heartburn. At one month of postoperative follow-up, the reflux symptom index (RSI) score was (3.1±2.9) points, and at three months, the RSI score was (2.4±1.4) points. Conclusions:The application of right-opening single flap valvuloplasty based on tubular stomach for gastrointestinal reconstruction after laparoscopic proximal gastrectomy is safe,feasible,and has satisfactory short-term efficacy.

Autoimmune disease is a kind of disease characterized by immune imbalance,abnormal activation of immune cells,massive production of inflammatory factors and immune complexes,which leads to the damage of multiple organs and systems.Autoimmune disease is easy to recur in clinical practice.The previous studies showed that there is a correlation between dampness syndrome in traditional Chinese medicine(TCM)and immune dysfunction.This paper explains the theoretical basis for the correlation between dampness syndrome of TCM and the recurrence of autoimmune diseases,and the similarities between the two in macro appearance,pathogenesis characteristics,etc.,analyzes the possible correlation about biological mechanism between dampness syndrome and autoimmune diseases,and discussed the correlation between pathogenic dampness of TCM and the recurrence of autoimmune diseases such as psoriasis,rheumatoid arthritis,ulcerative colitis,and nephrotic syndrome.It is pointed out that pathogenic dampness of TCM is an important pathogenic factor for the recurrence of autoimmune diseases,and is closely related to the recurrence of autoimmune diseases.Autoimmune diseases can be treated from the perspective of pathogenic dampness in TCM,and therapy of invigorating spleen,replenishing qi and removing dampness is frequently adopted,which is beneficial to alleviating the clinical symptoms of patients and reducing the recurrence of autoimmune disease.
