ABSTRACT

At present, countries around the world are paying greater attention to the protection of medicinal plants and traditional medicinal knowledge resources, and are looking for various ways to protect medicinal plants. Many countries have established their own databases to save the medicinal plant information resources. This paper focuses on the introduction of medicinal plant databases in six countries including Malaysia, Philippines, and Singapore, and compares their basic information. It is difficult to achieve integration and sharing among these databases. It brings certain difficulties to the use of researchers in related fields. It is suggested that the construction of a multinational common medicinal plant database should be included in the "Belt and Road Initiative" to systematically organize massive information, enhance exchanges between countries on traditional medicinal plants, and achieve medicinal plant information sharing, and the establishment of a shared database will reduce optimization and maintenance to a certain extent or renewal work, laying the foundation for the protection, development and sustainable use of traditional medicinal plant resources.

ABSTRACT

Lancang-Mekong countries refer to the six countries that the Lancang-Mekong River flows through, including China, Laos, Myanmar, Thailand, Cambodia, and Vietnam. These countries are geographically adjacent with similar cultures and have long history of traditional medicine and high plant diversity. Since ancient times, medicinal plants have been introduced into China from the countries along the river, including a variety of medicinal plants with edible and healthcare values, which is an important way for the transnational circulation of medicinal resources. This paper briefly described the history and application of edible medicinal plants in the six Lancang-Mekong countries and summarized more than 150 edible medicinal plants from the other five countries except China. These 150 medicinal plants belong to 66 families such as Labiatae, and 12 species of them are used as edible medicinal plants in all the six countries. Further, we collected the information of these edible medicinal plants, including the origins, efficacy, indications, medicinal edible parts, edible values, and the traditional application of these plants in China. Some valuable edible medicinal plants in the other five countries are considered to have a promising prospect of application in China and may be introduced to China as new medicinal resources. These efforts will be conducive to the cooperation in traditional medicine among Lancang-Mekong countries.

ABSTRACT

METRNL is a recently identified secreted protein with emerging functions. This study is to find major cellular source of circulating METRNL and to determine METRNL novel function. Here, we show METRNL is abundant in human and mouse vascular endothelium and released by endothelial cells using endoplasmic reticulum-Golgi apparatus pathway. By creating endothelial cell-specific Metrnl knockout mice, combined with bone marrow transplantation to produce bone marrow-specific deletion of Metrnl, we demonstrate that most of circulating METRNL (approximately 75%) originates from the endothelial cells. Both endothelial and circulating METRNL decrease in atherosclerosis mice and patients. By generating endothelial cell-specific Metrnl knockout in apolipoprotein E-deficient mice, combined with bone marrow-specific deletion of Metrnl in apolipoprotein E-deficient mice, we further demonstrate that endothelial METRNL deficiency accelerates atherosclerosis. Mechanically, endothelial METRNL deficiency causes vascular endothelial dysfunction including vasodilation impairment via reducing eNOS phosphorylation at Ser1177 and inflammation activation via enhancing NFκB pathway, which promotes the susceptibility of atherosclerosis. Exogenous METRNL rescues METRNL deficiency induced endothelial dysfunction. These findings reveal that METRNL is a new endothelial substance not only determining the circulating METRNL level but also regulating endothelial function for vascular health and disease. METRNL is a therapeutic target against endothelial dysfunction and atherosclerosis.

ABSTRACT

Objective:To optimize the challenge scheme for establishing a stable mouse model of Artemisia annua pollen-induced allergic rhinitis. Methods:BALB/c mice were subcutaneously injected with 0.1 ml allergen extract containing 20 μg/ml Art a1 from Artemisia pollen on 1 d, 4 d and 7 d. One week after the sensitization, these mice were divided into three groups and intranasally challenged with Artemisia annua pollen allergen extract containing 500 μg/ml Art a1 for 7 (7 d group), 10 (10 d group) and 14 (14 d group) consecutive days, respectively. The first challenge was followed by another 7 days of challenge every four weeks. Blank control group was set up through sensitizing and challenging BALB/c mice with normal saline. Behavioral changes and nasal pathological changes were observed. The changes in humoral and cellular responses were also detected. After the first challenge cycle was decided, the challenge frequency was further optimized. Results:After the first challenge, the allergic symptoms of mice in 10 d group were significantly severe than those in 7 d and 14 d groups, and the levels of serum specific IgE antibody in 10 d and 14 d groups were significantly higher than that in 7 d group. After the second challenge, the mice in the three model groups still had obvious allergic symptoms as compared with the blank control group. There were obvious pathological changes in the nose, including epithelial cell proliferation, turbinate enlargement and inflammatory cell increase. Moreover, the level of serum specific IgE antibody increased significantly and the proliferation of antigen-specific IL-4 and IL-6 lymphocytes was significantly up-regulated, especially in 10 d and 14 d groups. The frequency of challenge had a great impact on the stability of the allergic model. The allergic symptoms of sensitized mice challenged every two weeks were significantly severe than those of mice challenged every four weeks and the level of serum antigen-specific antibody was also higher.Conclusions:This study optimized the first challenge cycle and challenge frequency for establishing a mouse model of Artemisia annua pollen-induced allergic rhinitis, which provided reference for the establishment of drug efficacy evaluation system for desensitization therapy.

ABSTRACT

Short segment lesions in the middle and upper segment of popliteal artery caused by acute plaque events can lead to moderate and severe limb ischemia, but there is little professional attention and research reports. The effect of rapamycin eluting stent in the treatment of short segment popliteal artery lesions was reviewed. The characteristics, operation methods and follow-up results of 4 cases were analyzed to summarize the operation experience and evaluate the treatment effect. In 4 cases, the operation time was short, the operation was smooth, and the technical success rate was 100%. The blood flow of the stent was good, no complications such as displacement, rupture and vascular injury were found, and the blood supply of the lower limbs was improved satisfactorily. Rapamycin eluting stent implantation can achieve good medium and long-term results in the treatment of specific middle and upper popliteal artery lesions.

ABSTRACT

Objective To investigate the medication adherence of military academy students with superficial mycoses. Methods A 8-item Morisky medication adherence scale (MMAS) was modified into 7-item scale to evaluate the compliance of antifungal drugs in the sick students. The reliability and validity of the scale were analyzed. Results A total of 243 questionnaires were collected, of which 242 were valid questionnaires. 90.08% of the students took topical medication and 8.68% were treated both with topical and systematic combination. High, medium and low medication adherence rates as assessed by the modified MMAS were 9.09%, 23.97% and 66.94%, respectively. The reliability analysis showed that the internal consistency coefficient (Cronbach’s α ) was 0.781,and the adjusted Cronbach’s α was 0.790, indicating the high reliability of the scale. The KMO value was 0.798, and the Bartlett’s spherical test value was 440.866, P=0.000. One factor was extracted by exploratory factor analysis. The factor loadings of the items were all above 0.5. Therefore, the high convergent validity was good. Conclusion The modified MMAS has good reliability and validity and is applicable for the evaluation of medication compliance for superficial mycoses. In this study, the military students have a low level of medication adherence for superficial mycoses. Effective measures should be taken to help students strengthen their daily medication management and improve compliance.

ABSTRACT

With the breakthrough of immune checkpoint blocking therapy in the clinical treatment of a variety of malignant solid tumors, tumor immunotherapy has opened a new era. However, clinical practice has proved that the response rate of this therapy is low. Seeking for the key factors limiting its response rate has become a research hotspot in this field. Programmed death ligand 2 (PD-L2) is the second important ligand binding to programmed death 1 (PD-1) after programmed death ligand 1 (PD-L1). The encoded protein can bind to PD-1 and then inhibit immune cells. This paper reviews the biological characteristics of PD-L2, its mechanism in immune regulation and its research progress in solid tumor immunotherapy to provide more theoretical support for solid tumor immunotherapy.

ABSTRACT

Objective:To investigate the feasibility of shear wave elastography (SWE) to evaluate the protective effect of testicular compartment decompression on spermatogenesis after testicular torsion reduction.Methods:Thirty-two rabbits were randomly divided into 4 groups: control group (S group), testicular torsion simple reduction group (I group), and testicular torsion reduction+ compartment decompression group (T group: T1 group, T2 group), 8 rabbits per group. After the complete testicular torsion model was established in the I and T groups, the I group was simply reperfused, and the T group was reperfused before decompression of the compartment. Rabbits in each group were kept for 30 days after successful modeling. Each group of rabbits underwent testicular fascia intracompartment pressure measurement and SWE examination before operation, after successful complete torsion modeling, after reperfusion and 30 days later. After the experiment, the surgical side testicles were taken for pathological examination.Results:After testicular torsion, the pressure of testicular fascia and the average Young′s modulus (Emean) of testicular tissue in each experimental group increased (all P<0.05), and further increased with the extension of torsion time (all P<0.05). After reperfusion, the testicular fascial compartment pressure and testicular tissue Emean value in group I further increased (all P<0.05), while the testicular fascial compartment pressure and testicular tissue Emean value in group T decreased (all P<0.05). Thirty days later, testicular fascial compartment pressure and testicular tissue Emean value in group I were higher than those in group T (all P<0.05), while Johnsen′s score of testicular tissue was lower than that in group T ( P<0.05), and testicular tissue apoptosis index and malondialdehyde content were higher than those in group T Group T (all P<0.05). Conclusions:Decompression of the testicular compartment has a protective effect on spermatogenesis after testicular torsion reduction. SWE can indirectly evaluate the severity of testicular compartment syndrome after testicular torsion and reduction, and the protective effect of compartment decompression on spermatogenesis.

ABSTRACT

Objective:To investigate the clinical therapeutic effect of low-dose chemotherapy in advanced gastrointestinal cancer patients with weak physical condition, and to evaluate the related factors affecting the prognosis.Methods:The clinical data of 118 advanced gastrointestinal cancer patients with weak physical condition who were admitted to Xiamen Branch, Zhongshan Hospital, Fudan University from March 2018 to May 2019 were retrospectively analyzed. Kaplan-Meier method was used to make survival analysis in patients stratified by different factors, and log-rank was used to test. Multiple factor analysis of prognosis was performed by using Cox regression model. The association of clinicopathological factors with the prognosis was evaluated.Results:Among 118 patients, 16 (13.6%) cases were esophageal cancer, 41 (34.7%) cases were gastric cancer, 48 (40.7%) cases were colorectal cancer, 13 (11.0%) cases were pancreatic cancer. The overall survival (OS) rates of 6 months and 1-year were 44.1% and 10.2%, respectively. Survival analysis showed that patients with hemoglobin ≥100 g/L, serum albumin > 40 g/L and normal gastrointestinal function had better OS (all P < 0.05), while patients with physical status score of 3 scores and pain had worse OS (all P < 0.05). Cox multivariate analysis showed that after adjusting age and gender, hemoglobin level ( HR = 0.314, 95% CI 0.241-0.977, P = 0.001), pain ( HR = 2.016, 95% CI 1.697-7.038, P = 0.008) and gastrointestinal function ( HR = 1.751, 95% CI 1.607-6.080, P = 0.036) were independent influencing factors of OS in advanced gastrointestinal cancer patients with weak physical condition after receiving low-dose chemotherapy. Conclusions:Low-dose chemotherapy can still benefit advanced gastrointestinal cancer patients with weak physical condition. Hemoglobin level, pain and gastrointestinal function are independent prognostic factors for these patients.

ABSTRACT

Objective:To explore the value of contrast-enhanced ultrasound and its quantitative analysis technology in the evaluation of testicular microvascular injury caused by chronic alcoholism, as well as its relationship with the morphological changes of testicular spermatogenic cells.Methods:Seventy-two New Zealand white rabbits were randomly divided into control group (S group), low-dose alcohol group (L group), medium-dose alcohol group (M group), and high-dose alcohol group (H group). Then, the rabbits were subdivided into the groups of S1, S2, S3, L1, L2, L3, M1, M2, M3, H1, H2, H3 according to different time points (30 d, 60 d, 90 d). The rabbits in each group were examined by routine ultrasound before the experiment, followed by contrast-enhanced ultrasound examination. Testicular tissues were taken for pathological examination under light and electron microscope.Results:①The peak intensity and area under the curve of ultrasound contrast parameters gradually decreased with the increase of dosage and duration of alcohol feeding (all P<0.05), and the curvature also gradually decreased (all P<0.05). The differences of peak time, mean transit time, and peak half-time were not statistically significant (all P>0.05). ②With the increase of alcohol dosage and duration under the light microscope, the seminiferous tubule epithelium gradually became thinner, and the sperm in the cavity gradually decreased or no sperm was produced. The Johnsen′s score of testicular tissue decreased with the increase of alcohol dosage and duration (all P<0.05). The cytoplasmic mitochondria of the microvascular endothelial cells were vacuolated under the electron microscope. With the dosage and duration of alcohol feeding, the endothelial cells were vacuolated and even shed, and the basement membrane was interrupted. Conclusions:Alcohol could damage the testicular microvessels and spermatogenic cells in a dose-effect and time-effect relationship. Contrast-enhanced ultrasound can be used to evaluate the microvessel damage of testis caused by chronic alcoholism and indirectly reflect the morphological changes of spermatogenic cells.

ABSTRACT

Objective:To analyze the clinical value of serum 2019 novel coronavirus (2019-nCoV) immunoglobulin M (IgM) and immunoglobulin G (IgG) antibodies in the diagnosis of COVID-19.Methods:A total of 116 patients diagnosed with NCP in the First Affiliated Hospital of Hunan University of Chinese Medicine and the First Affiliated Hospital of Xiamen University were enrolled from January to February 2020 as the disease group. A total of 134 cases, including 84 non-NCP inpatients and 50 healthy individuals served as the control group. Serum samples from all subjects were collected. A fully-automated chemiluminescence immunoassay analyzer was used to detect the concentration of 2019-nCoV IgM and IgG antibodies in serum. The sensitivity and specificity of the 2019-nCoV IgM and IgG antibody single test and combined detection were compared using the χ 2 test. χ 2 test and Wilcoxon′s rank sum test were used to compare the positive rates and concentrations of IgM and IgG antibodies in NCP patients before and after their 2019-nCoV nucleic acid tests turning negative, respectively. The change trend of 2019-nCoV antibody concentration in the process of NCP patients was analyzed by Wilcoxon′s rank sum test. Results:The sensitivity of 2019-nCoV IgG (90.5%, 105/116) was higher than that of 2019-nCoV IgM (75.9%, 88/116), the difference was statistically significant (χ 2=8.91, P<0.05); The specificity of 2019-nCoV IgG (99.3%,133/134) was higher than that of 2019-nCoV IgM (94.0%, 126/134), the difference was statistically significant (χ 2=5.63, P<0.05). The sensitivity (89.7%,87/97) of 2019-nCoV IgM combined with IgG was higher than that of 2019-nCoV IgM, the difference was statistically significant (χ 2=6.89, P<0.05). The specificity (100%, 125/125) of 2019-nCoV IgM combined with IgG was higher than that of 2019-nCoV IgM, the difference was statistically significant (χ 2=7.70, P<0.05). After 2019-nCoV nucleic acid test converted to negative, the positive rate (9/17) and concentration [13.0 (4.9, 24.7) AU/ml] of serum 2019-nCoV IgM antibody were significantly lower than those when the nucleic acid test was positive, positive rate (15/17) and concentration [29.5 (14.0, 61.3) AU/ml], respectively (χ 2=5.10, Z=-3.195, both P<0.05). In the course of NCP, patients′ serum samples were collected from the first day of diagnosis to every three days, three times in total. The first 2019-nCoV IgM and IgG antibody concentrations [19.4 (12.4, 63.7) AU/ml, 105.8 (74.8, 126.1) AU/ml, respectively] were significantly higher than the second concentrations [15.8 (7.1, 40.3)AU/ml, 80.5 (66.7, 105.9) AU/ml], Z were-2.897,-3.179, both P<0.05. Conclusions:2019-nCoV IgG antibody has a good application value in the diagnosis of NCP. The concentration of 2019-nCoV IgM antibody has a certain correlation with the detection of 2019-nCoV nucleic acid. The combination of 2019-nCoV IgM and IgG antibodies with 2019-nCoV nucleic acid test may be the best laboratory index for the diagnosis of NCP at present.

ABSTRACT

Objective:To evaluate the efficacy and safety of switch from prednisone (AA+ P) to dexamethasone (AA+ D) in metastatic castration-resistant prostate cancer patients (mCRPC) progressing on abiraterone plus prednisone.Methods:Between November 2016 and December 2019, 46 mCRPC patients were switched to AA+ D after progression on AA+ P at Sun Yet-sen University Cancer center. Median age was 72 years(50 to 89 years), with median androgen deprivation therapy (ADT) duration 14.6 months(2.1 to 168.5 months). PSA level at the time of diagnosis, the initiation of AA+ P treatment, the time of switch were 258.9 ng/ml, 56.6 ng/ml, 25.1 ng/ml, respectively. 42 (91.3%), 12(26.1%), 7(15.2%) patients had bone metastasis, lymph node metastasis, visceral metastasis, respectively. 28 patients had Gleason score ≥8, and 11 patients had Gleason score<8. The primary endpoint was progression free-survival (PFS). Secondary endpoints included PSA response rate of PSA decline ≥50% and ≥30% and safety. Patients were divided into different risk level groups according to PSA level at the time of switch and PFS on AA+ P.Results:The median follow-up of 46 patients was 4.9 months, 40 patients progressed at the last follow-up, the treatment was terminated in 1 patient because of cerebral infarction, 5 patients were still on the treatment of AA+ D. Median PFS on AA+ D of 46 patients was 3.7 (1.6-24.1) months. A total of 12 (26.1%) patients showed a PSA decline≥50% after treatment with AA+ D, and 21 (45.7%) patients showed a PSA decline ≥30%. The median PFS was 8.5 (2.7-24.1) and 3.0 (1.6-17.8) months for patients with PSA decline≥50% and PSA didn’t decline ≥50%, respectively. Four factors below were significantly associated with a longer PFS on AA+ D after steroid switch in univariate analysis: lower PSA level at the time of switch (<30 ng/ml, HR=0.30, 95% CI 0.14-0.64, P=0.002), longer ADT sensitivity duration (≥18 months, HR=0.55, 95% CI 0.28-1.06, P=0.045), longer AA+ P treatment PFS (≥8 months, HR=0.36, 95% CI 0.18-0.72, P=0.004), and greater PSA decline on AA+ D (≥50%, HR=0.30, 95% CI 0.17-0.75, P=0.007). The above mentioned factors were also independent prognostic factors associated with better PFS on AA+ D after steroid switch in multivariate analysis. Treatment with AA+ D was well tolerated in all patients, with no grade 3/4 toxicity reported. Conclusions:Switching from prednisone to dexamethasone is effective and safe in mCRPC patients progressing on abiraterone plus prednisone. Patients with lower PSA level at the time of switch, longer ADT sensitivity duration, longer AA+ P treatment PFS and greater PSA decline on AA+ D might gain better efficacy.

ABSTRACT

Objective:To investigate the clinical effect of Naoxintong capsule combined with levamlodipine tablets in the treatment of essential hypertension.Methods:From February 2018 to February 2019, 182 cases of essential hypertension were selected in Jiangshan Hospital of Traditional Chinese Medicine and divided into treatment group (91 cases) and control group (91 cases) according to the random digital table.The treatment group was treated with Naoxintong capsule combined with levamlodipine tablets, while the control group was treated with levamlodipine tablets.Both two groups were treated for 12 weeks.The therapeutic effects, blood pressure, urinary microalbumin (MAU), vascular endothelial function and inflammatory mediators before and after treatment were compared between the two groups.Results:The total effective rate of the treatment group[91.21%(83/91)]was higher than that of the control group[79.12%(72/91)](χ 2=5.262, P<0.05). After treatment, SBP[(132.36±8.27)mmHg], DBP[(84.35±5.32)mmHg]and MAU[(26.47±5.47)mg/L] in the treatment group were lower than those in the control group[(139.62±6.58)mmHg, (89.74±4.12)mmHg and (33.82±3.76)mg/L]( t=6.553, 7.641, 10.563, all P<0.05). The NO[(52.17±5.36)μmol/L]and FMD[(7.98±0.42)%] in the treatment group were higher than those in the control group[(41.09±7.28)μmol/L and (6.79±0.37)%], while ADMA[(0.23±0.06)μmol/L]in the treatment group was lower than that in the control group[(0.34±0.07)μmol/L], the differences were statistically significant( t=11.692, 20.281, 11.382, all P<0.05). The serum levels of IL-1[(128.32±13.25)ng/L] and IL-4[(24.35±5.71)ng/L] in the treatment group were lower than those in the control group[(173.79±23.19)ng/L and (32.19±6.57)ng/L], while the serum IL-10 level[(23.54±3.25)ng/L] in the treatment group was higher than that in the control group[(18.09±4.86)ng/L], the differences were statistically significant( t=16.240, 8.592, 8.892, all P<0.05). Conclusion:Naoxintong capsule combined with levamlodipine tablets is effective in the treatment of essential hypertension, which can reduce MAU, improve vascular endothelial dysfunction and alleviate inflammation.

ABSTRACT

Objective:Exploring the risk factors of recurrent laryngeal nerve injury in thyroid surgery.Methods:The hundred and sixteen patients undergoing secondary thyroid surgery from January 2016 to January 2019 were selected in the general surgery department of the First Affiliated Hospital of Harbin Medical University. The patients were divided into an injury group ( n=20) and a control group ( n=296) according to whether the recurrent laryngeal nerve injury occurred after the secondary operation. SPSS 23.0 was used to perform univariate analysis and multivariate regression analysis. Results:The total injury rate of recurrent laryngeal nerve in secondary thyroid surgery was 6.33% (20/316). In the univariate analysis, the size of the thyroid, the first operation, the interval between two operations, the tumor aggressiveness, the secondary operation, and whether nerve monitoringa were statistically significant in the injury group and the control group( χ2=1.495, 1.503, 1.628, 1.299, 1.938, 1.262, P<0.05). Logistic regression analysis showed that the size of the thyroid gland ( OR=4.962, P=0.001), the first operation ( OR=12.296, P=0.002), the interval between two operations ( OR=3.590, P=0.025) and the secondary operation ( OR=2.319, P=0.002) were an independent risk factors for recurrent laryngeal nerve injury in secondary thyroid surgery. Conclusions:Secondary thyroid surgery is more likely to cause recurrent laryngeal nerve damage. For the thyroid disease with a high risk of recurrence, total thyroidectomy should be selected for the first surgery to to avoid the risk of complications caused by secondary surgery; For some complicated secondary surgery patients, the use of recurrent laryngeal nerve monitoring technology during operation can minimize the recurrent laryngeal nerve injury and improve the patient′s postoperative quality of life.

ABSTRACT

During a short period of time, the outbreak of pneumonia caused by a novel coronavirus, named Novel Coronavirus Pneumonia (NCP), was first reported in China, spreading to 24 countries and regions rapidly. The number of confirmed cases and deaths continued to rise. World Health Organization (WHO) announced that the outbreaks of the novel coronavirus have constituted a Public Health Emergency of International Concern. Efficient infection control can prevent the virus from further spreading, which makes the epidemic situation under control. Due to the specialty of oral healthcare settings, the risk of cross infection is severe among patients and oral healthcare practitioners. It's more urgent to implement strict and efficient infection control protocols. This paper, based on existing guidelines and published researches pertinent to dental infection-control principles and practices, mainly discusses epidemiological characteristics of NCP and the features of nosocomial infection in oral healthcare settings, and furthermore provides recommendations on patient's evaluation, and infection control protocols in department of stomatology under current circumstance..

ABSTRACT

Objective@#To report the experience on the multi-disciplinary management of metastatic renal cell (mRCC) patients in a single center.@*Methods@#Data of 168 mRCC patients treated by multi-disciplinary team (MDT) at Sun Yat-sen University Cancer Center from December 2007 to February 2019 was retrospectively analyzed.Three treatment groups were identified, including 76 patients with 55 males and 21 females, received anti-angiogenic agents alone (Group A), 66 patients with 55 males and 11 males, received anti-angiogenic agents plus local therapy (Group B)and 26 patients, with 19 males and 7 females, received anti-angiogenic agents plus immunotherapy and local therapy (Group C). The Sunitinib, Sorafenib, Axitinib were chosen for the TKI. The Pembrolizumab was used for immunotherapy. The stereotactic body radiation therapy and surgical excision were considered as the local therapy. The study aims to compare the age, gender, IMDC score, pathology, nbephrectomy, adverse events, progression-free survival and overall survival (OS).@*Results@#Of all patients, the median follow-up duration was 23 months (ranging 6-117 cmonths). The PFS was 18.3 months and median OS was 33.5 months. The 2 years and 5 years survival rate was 66% and 35%, respectively. The median OS of Group A, B and C were 29.8 months, 44.6 months and not reached. 2y-OS was 58%, 67% and 89%, while 5y-OS 12%, 46% and 57%.There was no difference in age, gender, IMDC score, pathology, synchronous metastases or nephterectomy between the three groups. The prognostic result in TKI based combination therapy was superior to TKI therapy alone, which the 5y-OS was 51% and 11%, respectively. The prognostic result in group C's moderate-high risk mRCC patients was superior to group A and B. The median OS in TKI+ DC and CIK+ Pembrolizumab was 49.1 months and 53.1 months. On univariate analyses, IMDC score, nephrectomy and treatment group was associated with OS (P<0.05). On multivariate analyses, treatment group, nephrectomy was associated with OS (P<0.05). The risk of death of Group C decreased about 60% [HR 0.39 (0.17, 0.89), P=0.026]. 78 (46.4%) patients on TKI alone and 16 (61.5%) patients treated with TKI plus immunotherapy had Grade 3 or 4 adverse events. 16 (20.3%) patients had Clavien Ⅲ-Ⅳ toxicity after surgical procedures. 6 (5.7%) patients had Grade 3 toxiciy after SBRT.@*Conclusions@#Patients treated with combined therapy had better survival than those treated with anti-angiogenic agents alone. MDT approach could bring survival benefit to mRCC patients.

ABSTRACT

Atherosclerosis is a complex and multi-factorial pathophysiological process. Researches over the past decades have shown that the development of atherosclerotic vulnerable plaque is closely related to its components, morphology, and stress status. Biomechanical models have been developed by combining with medical imaging, biological experiments, and mechanical analysis, to study and analyze the biomechanical factors related to plaque vulnerability. Numerical simulation could quantify the dynamic changes of the microenvironment within the plaque, providing a method to represent the distribution of cellular and acellular components within the plaque microenvironment and to explore the interaction of lipid deposition, inflammation, angiogenesis, and other processes. Studying the pathological mechanism of plaque development would improve our understanding of cardiovascular disease and assist non-invasive inspection and early diagnosis of vulnerable plaques. The biomechanical models and numerical methods may serve as a theoretical support for designing and optimizing treatment strategies for vulnerable atherosclerosis.

ABSTRACT

" Day surgery hospital-community joint follow-up model " results newly from the deepening implementation of the hierarchical medical system policy. It is designed to follow up the patients discharged from hospital but not fully recovered in time to ensure the prevention of adverse events after surgery. It can also improve the quality and efficiency of follow-up, and ensure the safety and integrity of the whole day operation management. In this context, through a comparative study of 720 patients discharged from daytime surgery in the region, patients in the combined follow-up group were followed up by telephone on the 3rd day after the operation by nurses from the day surgery ward. On the 10th and 20th days after the operation, the family doctor from the community health service center will visit the patient at home and follow up the patient by telephone. One month later, the patient returned to the hospital for follow-up consultation. Follow-up results show day surgery hospital-community joint mode as a helpful aid in keeping track of the patients postoperative rehabilitation, reducing complications and handling in time, while improving the ambulatory surgery perioperative safety.
