Objective:To investigate the effect of "four-staff co-management" follow-up mode on risk factor control and medium-term prognosis improvement in patients with coronary heart disease after percutaneous coronary intervention (PCI).Methods:This was a intervention study. Patients with coronary heart disease who were admitted to the Xiamen Cardiovascular Hospital of Xiamen University from June 2021 to January 2022 and successfully discharged after PCI were included. According to the different types of follow-up after discharge, patients were divided into the traditional follow-up group and the "four-staff co-management" follow-up group. The "four-staff co-management" follow-up mode means that specialists, specialist managers in third-level A hospitals and general practitioners and health managers in basic hospitals were jointly responsible for post-discharge follow-up of PCI patients. Baseline clinical data were collected. The primary endpoints were the rate of compliance of coronary heart disease risk factor control at 12 months after surgery, the rate of secondary surgery, and the incidence of mid-term major adverse cardiovascular and cerebrovascular events (MACCE). Unplanned secondary PCI included symptom-driven secondary PCI and asymptomatic secondary PCI. MACCE includes myocardial infarction, hospitalization for heart failure, stroke, major bleeding, all-cause death, and composite endpoints including these events.Results:A total of 2 181 patients were enrolled, including 1 097 patients in the traditional follow-up group and 1 084 patients in the "four-staff co-management" follow-up group. At baseline, there were no statistically significant differences in gender, age, discharge diagnosis, co-existing diseases, echocardiographic indexes, and coronary artery lesions between the two groups (all P>0.05). There were no significant differences between the two groups in total PCI stent length, maximum internal diameter of stent, proportion of patients using drug balloon, proportion of patients with a planned second surgery during hospitalization, and discharge with drugs (all P>0.05). Twelve months after PCI, the reduction in HbA1c and low-density lipoprotein cholesterol was greater in the "four-staff co-management " follow-up group than that in the traditional follow-up group (all P<0.05), and the rate of reaching the standard for low-density lipoprotein cholesterol was higher than that in the traditional follow-up group ( P=0.001), but there was no statistical significance between the two groups for blood pressure and blood glucose (all P>0.05). During the follow-up period, the proportion of symptom-driven second operation patients was lower in the "four-staff co-management" follow-up group than that in the traditional follow-up group ( P<0.001), and there was no significant difference in the proportion of asymptomatic second operation patients between the two groups ( P=0.191). The proportion of hospitalized patients with heart failure in the "four-staff co-management" follow-up group was lower than that in the traditional follow-up group ( P=0.029), and there was no significant difference in the proportion of myocardial infarction, cerebral infarction, cerebral hemorrhage, massive hemorrhage, death and complex endpoint events between the two groups (all P>0.05). Conclusion:The "four-staff co-management" follow-up mode can effectively improve the control of risk factors and medium-term prognosis in patients with coronary heart disease after PCI.

ResultsA total of 15 researches were included, from ten countries, involving 520 participants, who were healthy elderly individuals or those with mild cognitive impairment. Various neurofeedback waveforms were utilized, such as alpha, beta, theta, beta/alpha, and sensorimotor rhythm (SMR) waves. Intervention duration ranged from 20 to 90 minutes, with intervention frequencies spanning from a long-term intervention of 30 sessions over 12 weeks to a high-frequency short-term intervention of eight sessions over one week. The primary health outcomes focused on cognitive function, including memory, attention, inhibitory control and executive function. ConclusionNeurofeedback training can improve the cognitive function of the eldery, and alleviate cognitive aging.

Malignant hepatobiliary tumors mainly include hepatocellular carcinoma (HCC) and biliary tract cancer (BTC) and are common malignancies in China that seriously threaten the life and health of the Chinese people. Malignant hepatobiliary tumors often have an insidious onset, and most patients have lost the opportunity for surgery due to the advanced stage at initial diagnosis. The treatment of advanced HCC mainly depends on systemic therapy such as sorafenib, lenvatinib, donafenib, regorafenib, apatinib, and systemic chemotherapy, but such treatment often has a limited effect. The treatment of advanced BTC mainly relies on systemic chemotherapy, which often has an unsatisfactory effect. The advent of the era of immunotherapy brings new hope to the treatment of advanced malignant hepatobiliary tumors. Atezolizumab combined with bevacizumab and sintilimab combined with a bevacizumab biosimilar IBI305 have been approved as the first-line treatment of advanced HCC. The treatment regimens, such as Chemotherapy-based immune checkpoint inhibitor (ICI) or ICI combined with targeted drugs, have made great progress in the treatment of advanced BTC, and although these regimens can significantly improve the overall survival of patients, they often bring obvious and even life-threatening adverse reactions, which should be taken seriously by clinicians. In addition, further studies are needed to investigate the value of ICI-based combination therapy in the perioperative treatment of malignant hepatobiliary tumors.

Objective:To analyze the epidemiological and clinical characteristics of hospitalized patients with dengue fever in Guangdong Province in 2019, so as to provide reference for clinical diagnosis and treatment of dengue fever.Methods:The general data, laboratory examination data, clinical manifestations and prognosis data of 480 inpatients with dengue fever admitted to Eight People′s Hospital Affiliated to Guangzhou Medical University between January 4 and October 31, 2019 were analyzed retrospectively. The clinical and onset characteristics of patients with dengue fever were described.Results:Among 480 dengue patients, 442(92.1%) were dengue fever, 38(7.9%) were severe dengue, and 136(28.3%) had underlying diseases. The peak age of onset was mainly in young adults aged 20 to 49 years old, accounting for 66.0%(317/480) in total. The seasonal peak was mainly in August to October. There were 399(83.1%) local cases and 61(12.7%) imported cases. The most common clinical manifestations were fever (98.1%, 471/480), chills (72.9%, 350/480), headache (58.5%, 281/480) and bone/joint/muscle pain (67.1%, 322/480), followed by digestive tract symptoms and respiratory tract symptoms. Among 446 serum samples, 358 (80.3%) were dengue virus (DENV)-1, 54 (12.1%) were DENV-2, 34 (7.6%) were DENV-3. The main laboratory tests of the patients were leucopenia (65.8%, 316/480), low hematocrit (30.2%, 145/480), thrombocytopenia (48.3%, 232/480), neutropenia (44.8%, 215/480), elevated alanine aminotransferase (ALT) (37.7%, 181/480) and aspartate aminotransferase (AST) (59.4%, 285/480). Treatment mainly adopted symptomatic support treatment and active prevention of complications. The length of stay was (5.8±3.1) days (range 1.0-38.0 days). A total of 461(96.0%) patients were cured or improved.Conclusions:In 2019, the majority of dengue fever patients in Guangdong Province are young adults aged 20 to 49 years old, and the proportion of severe patients is high, with DENV-1 infection as the main type. After symptomatic support treatment and active prevention of complications, most of the dengue fever patients have a good prognosis.

Objective:To explore the risk factors influencing the prognosis for patients with hepatocellular carcinoma (HCC) recurrence after liver transplantation and summarize the relevant diagnostic and therapeutic experiences.Methods:The clinicopathological features with diagnosis and treatment plan of 102 recurrent HCC patients fulfilling the Fudan Criteria were compared for survival rate (univariate analysis) and independent prognostic indicators were obtained by Cox multivariate analysis.Results:The 1/3/5-year overall survival rates were 92.2%, 48.6% and 34.6% and the 1/3/5-year survival rates with tumor were 63.2%, 31.0% and 16.7% respectively. Cox regression analysis indicated that patient age, whether tumor can be surgically resected or not and personalized diagnostic & therapeutic plan based upon targeted therapy were independent prognostic factors affecting the overall survival rates and survival rates with tumor.Conclusions:Although HCC recurrence and metastasis after liver transplantation seriously influence patient prognosis, satisfactory outcomes may be obtained for some patients through active, effective and precise managements.

The clinical application of immune checkpoint inhibitors (ICIs) has significantly improved the prognosis of hepatocellular carcinoma (HCC) patients. With the widespread applica-tion of ICIs in HCC, the management of immune-related adverse events (irAE) gained more and more attention. However, the complicated disease characteristics and various combination therapies in HCC throw out challenges to irAE management. Therefore, the editorial board of the 'Chinese expert consensus on the management of immune-related adverse events of hepatocellular carcinoma treated with immune checkpoint inhibitors (2021 edition)' organizes multidisciplinary experts to discuss and formulate this consensus. The consensus focuses on issues related to HCC irAE manage-ment, and puts forward suggestions, in order to improve standardized and safety clinical medication, so as to maximize the benefits of immunotherapy for patients.

Objective To compare differences in mechanical stability of intramedullary fibular allograft with cannulated screw (modified method) and cannulated screw alone (conventional method) for fixing young and middle-aged Pauwels Ⅰ, Ⅱ, Ⅲ femoral neck fractures. Methods Models of Pauwels Ⅰ, Ⅱ, Ⅲ femoral neck fracture fixed by conventional method and modified method were constructed. Stress distributions on weight-bearing area of the femoral cortical bone shell and the end of femoral neck fracture, as well as shear stress distributions on cortical bone shell of the femoral head and femoral neck fracture surface were analyzed, the maximum principal strain cloud maps of the femur in coronal position were drawn according to the predicted data, and the displacements of femoral neck fracture end between two groups were compared. Results The shear stress distributions on cortical bone shell of the femoral head in two directions (S12, S13) showed that femoral neck fractures fixed by modified method was superior or close to that by conventional method. Besides, the shear stress distributions on fracture surface of the femoral neck in two directions (S12, S23) showed that modified internal fixation was superior to conventional internal fixation. The displacements of femoral neck fracture end in Pauwels Ⅱ and Ⅲ fracture fixed by conventional method were greater than those by modified method and the displacements of Pauwels Ⅱ fracture fixed by conventional method were obviously larger than those of Pauwels Ⅱ fracture fixed by modified method. But Pauwels Ⅰ fracture fixed by modified method showed a larger displacement than that fixed by conventional method. Conclusions Modified method is more suitable for fixing femoral neck fracture with large angles (Pauwels Ⅱ and Ⅲ fracture), and conventional method is more suitable for fixing neck fracture with small angles (Pauwels Ⅰ fracture).

OBJECTIVE： To investigate the potential pharmacological mechanism of the seed of Draba nemorosa， and to provide reference for further development， utilization and clinical application. METHODS： Effective components and related target proteins of D. nemorosa were screened and identified by using TCMSP and STRING database. Cytoscape 3.7.0 software was used to construct a visual network of effective components and target proteins for the seed of D. nemorosa， and the network topology analysis was performed. The targeting protein-protein interaction （PPI） network was constructed and analyzed by STRING database and Cytoscape 3.7.0 software. KEGG pathway enrichment of target proteins was analyzed by DAVID bioinformatics resource database. RESULTS： A total of 9 effective components were screened from the seed of D. nemorosa， including quercetin， kaempferol， β-sitosterol， etc. Totally 174 target proteins were obtained， mainly including PTGS2， NCOA2， PGR， etc. Among them， JUN and MAPK1 were core proteins in PPI network. KEGG enrichment pathway included PI3K/Akt signaling pathway， TNF-α signaling pathway， HIF-1 signaling pathway， Toll-like receptor signaling pathway and thyroid hormone signal pathway， etc. CONCLUSIONS： Effective components from the seed of D. nemorosa such as quercetin， kaempferol and β-sitosterol may act on PTGS2， JUN and MAPK1 target proteins through PI3K-Akt signaling pathway and TNF-α signaling pathway， thus exert the effects of purging lung， relieving asthma， promoting edema and reducing edema.
