Abstract
Objective: To analyze the dynamic development of physical, psychological, and cognitive degenerative multimorbidity among middle-aged and older Chinese adults (≥45 years old) while estimating the longitudinal association between socioeconomic status (SES) and the progression of multimorbidity. Methods: Based on data from the China Health and Retirement Longitudinal Study (2011-2020), the Sankey diagram was used to show the dynamic development of physical, psychological, and cognitive degenerative multimorbidity from 2011 to 2020. SES was constructed based on the level of education and total household wealth. Logistic regression was used to estimate OR and 95%CI to evaluate the association between SES and the progression of multimorbidity. Results: Of the 5 393 participants included, 4 484 (83.14%) of them developed new diseases, and the prevalence of physical, psychological, and cognitive degenerative multimorbidity increased from 38.04% to 74.23%. Compared to those with no reported disorders at baseline, participants with psychological disorder (for newly developed physical-cognitive multimorbidity: OR=4.59,95%CI: 2.89-7.29), cognitive disorder (for newly developed physical-psychological multimorbidity: OR=2.24,95%CI: 1.40-3.60), or their multimorbidity at baseline were more likely to progress to physical, psychological, and cognitive degenerative multimorbidity. After adjusting covariates, individuals with low SES were more likely to develop physical diseases (OR=1.45, 95%CI: 1.11-1.89), cognitive disorder (OR=1.84, 95%CI: 1.16-2.91), physical-psychological multimorbidity (OR=1.87, 95%CI: 1.37-2.56), physical-cognitive multimorbidity (OR=3.58, 95%CI: 2.54-5.06), psychological-cognitive multimorbidity (OR=5.66, 95%CI: 3.04-10.55), and physical-psychological-cognitive multimorbidity (OR=3.21, 95%CI: 2.06-5.01) in comparison to those with high SES. There is a dose-response relationship between SES and the multimorbidity progression (all trend P<0.001). Conclusions: The prevalence of physical, psychological, and cognitive degenerative multimorbidity increased significantly among middle-aged and older Chinese adults. Lower SES was associated with multiple patterns of physical, psychological, and cognitive disorders progression.

Abstract
Objective: To compare the efficacy between percutaneous mechanical thrombectomy and surgical thrombectomy in the treatment of acute arteriovenous graft thrombosis (AVG). Methods: The clinical data of acute thrombosis AVG patients treated in the Department of Vascular Surgery, Renji Hospital, School of Medicine, Shanghai Jiao Tong University from January 2020 to December 2021 were retrospectively analyzed. Patients were divided into percutaneous mechanical thrombectomy group and surgical thrombectomy group according to treatment methods. Baseline information, technical success rate, complication rate, and 24-month primary and secondary patency rates of the two groups were analyzed. Results: A total of 130 patients aged (54.1±14.2) years were enrolled in the study, including 66 males and 64 females. There were 78 patients in the percutaneous mechanical thrombectomy group and 52 patients in surgical thrombectomy group. No statistically significant differences in gender, age, comorbidities, and lesion characteristics between the two groups were detected (all P>0.05). The technical success rate in the mechanical thrombectomy group was 98.7% (77/78), and the complication rate was 5.1% (4/78), while the technical success rate in the surgical thrombectomy group was 94.2% (49/52), and the complication rate was 9.6% (5/52). There were no statistically significant differences in the technical success rate and complication rate between the two groups (all P>0.05). The average operation time of mechanical thrombectomy was significantly shorter than that of surgical thrombectomy [(62.8±13.9) min vs (77.0±17.6) min, P<0.001]. The Kaplan-Meier survival analysis indicated the primary patency rates of the mechanical thrombectomy group at 12 and 24 months after thrombectomy were 62.8% and 38.5%, respectively, while the primary patency rates of the surgical thrombectomy group at 12 and 24 months were 57.7% and 36.5%, respectively. There was no statistically significant difference in the primary patency rate between the two groups (P=0.641). The secondary patency rates of the mechanical thrombectomy group at 12 and 24 months were 98.7% and 94.9%, respectively, while the secondary patency rates of the surgical thrombectomy group at 12 and 24 months were 92.3% and 82.7%, respectively. The secondary patency rates of the mechanical thrombectomy group were higher than those of the surgical thrombectomy group (P=0.020). Conclusion: Mechanical thrombectomy is a safe and effective treatment for acute AVG thrombosis, with the advantages of shorter operation time and higher secondary patency rate compared with surgical thrombectomy.

Abstract
The Ion Cyclotron Range of Frequency (ICRF) heating system of the China Fusion Engineering Test Reactor (CFETR) is intended to provide plasma heating with a minimum power output of 20 MW, which demands the Radio Frequency (RF) window to possess a higher performance requirement. This paper presents the design of an RF window for the CFETR ICRF heating system and focuses primarily on the design and confirmation of its electromagnetic performance. The RF window can be effectively matched in the operating frequency range and has an S11 of under -59 dB. The geometry of the cone type ceramics was optimized to reduce the surface tangential electric field distribution. An analysis of the electric field distribution of the RF window at 50 kV indicates that the pressure side was below 2.3 kV/mm and the vacuum side was below 1.3 kV/mm. Furthermore, a transmission line test bench with an open-terminated setup was constructed to conduct withstand voltage tests on the mockup, and the results showed that the mockup could withstand 62 kV for 2 s and 47 kV for 120 s.

Abstract
Osteoarthritis (OA) is the most common form of arthritis and the leading cause of old age disability, affecting an estimated 302 million people worldwide. OA is seriously overlooked in the world. The awareness of OA and the popularization of standardized diagnosis and treatment are all lacking. Knees, hips, and hands are the most commonly affected joints in OA. Based on the experience of diagnosis and treatment, consensus and guidelines, we formulated this diagnosis and treatment standard in order to standardize the diagnosis and treatment of OA. We hope that our standard can reduce misdiagnosis and mistreatment and improve the prognosis of OA.

Abstract
With the progress of imaging technology and the popularization of healthy examination, the detection rate of pancreatic cystic neoplasm(PCN) has increased significantly. PCN has complex disease spectrum, strong heterogeneity, and diverse surgical treatment strategies. Surgical timing and methods directly affect patients' prognosis. Therefore, how to identify malignant tumors and formulate reasonable treatment strategies are the keys to treat PCN. Many guidelines for clinical diagnosis and treatment of PCN have been released, but there are still many disputes about its surgical indications. Hence, fully assessing the surgical indications is of great significance to improve the PCN patients' prognosis. This paper deeply discusses on the surgical indications of PCN by reviewing the current clinical diagnosis, treatment and research progress of PCN, in order to standardize the diagnosis and treatment of PCN.

Abstract
Ion cyclotron resonance heating (ICRH), one of the main auxiliary methods, for high-power and long-pulse plasma heating had been developed in Experimental Advanced Superconducting Tokamak (EAST). An impedance matching system, one important part of ICRH, had been developed for high-power injection and transmitter protection by reducing the reflected power from the antenna. The input impedance in the outlet of the stub tuner can be measured by voltage-current probes installed on the coaxial transmission line between the antenna and triple liquid stub tuners, and the optimum liquid levels in the stub tuners can be calculated based on the input impedance. The calculation and adjustment process of the optimum liquid levels are described comprehensively in this article. Finally, impedance matching had been achieved between two shots during EAST experiments. In the near future, a real-time impedance matching system will be developed to prevent large variations of the ICRH antenna impedance and achieve steady-state and long-pulse operation with the ICRH system.

Abstract
Objective: To evaluate the safety and clinical efficacy of percutaneous mechanical thrombectomy (PMT) through ipsilateral calf venous access in the treatment of entire-limb acute deep vein thrombosis (DVT). Methods: From July 2017 to August 2020, the clinical data of patients with entire-limb acute DVT at Renji Hospital, School of Medicine, Shanghai Jiaotong University treated by AngioJet through ipsilateral calf venous access were analyzed retrospectively. All patients received rivaroxaban or warfarin anticoagulant therapy for at least 6 months after operation. Pressure gradient socks were given routinely after operation. All patients were followed up at 3, 6, 12 months and every year after operation. The primary end points were the 12-month primary patency rate and the incidence of post thrombotic syndrome (PTS). The secondary end points included the thrombus clearance rate, total complication rate, bleeding complication rate and the 12-month incidence of moderate to severe PTS. Results: A total of 31 patients were included in the study. The age ranged from 31 to 80 (63±14) years, including 16 males and 15 females, 23 left lower limb DVT and 8 right lower limb DVT. There were 15 cases treated through peroneal venous access, 6 cases through anterior tibial venous access and 10 cases through posterior tibial venous access. Moreover, 9 cases underwent combined catheter-directed thrombolysis, 25 cases underwent iliac vein percutaneous transluminal angioplasty (PTA), and 10 cases underwent iliac vein stenting. The thrombus clearance rate was grade Ⅱ in 19 cases (61.3%) and grade Ⅲ in 12 cases (38.7%). One patient (3.2%) with anterior tibial venous access developed hematoma at the puncture site, which was improved after pressure bandage, and there were no other bleeding and serious complications. All the 31 patients were followed up for at least 12 months, with an average follow-up period of (22±9) months. The 12-month primary patency rate was 77.4% (24/31). The 12-month incidence of PTS was 16.1% (5/31) and the incidence of moderate to severe PTS was 3.2% (1/31). Conclusions: PMT through ipsilateral calf venous access is safe and effective in the treatment of entire-limb acute DVT. Thrombus in the distal popliteal vein can be one-stage removed and the incidence of PTS is low. It is considered as the first choice of access for the endovascular treatment of entire-limb acute DVT.

Abstract
Objective: To analyze the trend of morbidity and mortality of pancreatic cancer in China from 2005 to 2015 and estimate the related age, period and cohort effect, respectively. Methods: Joinpoint regression analysis was used to analyze the trend of morbidity rate and mortality rate of pancreatic cancer during 2005-2015 and calculate the annual percentage change and average annual percentage change based on the data in the annual report of China Cancer Registry. Population aged 20-84 years was fitted by the Age-Period-Cohort model to estimate the effect parameters of age, period and cohort. Results: The trend variations of the crude morbidity rate and crude mortality rate of pancreatic cancer were consistent. The morbidity rate of pancreatic cancer firstly increased before 2008 and then decreased. The morbidity rate and mortality rate of pancreatic cancer were higher in men than women, and higher in urban areas than in rural areas. From 2005 to 2015, the overall age-standardized morbidity rate of pancreatic cancer increased by 2.78% annually and the overall age standardized mortality rate of pancreatic cancer increased by 2.24% annually. The age standardized morbidity of pancreatic cancer in rural men changed more rapidly, with an average annual increase of 3.74%, and the age standardized mortality rate of pancreatic cancer in urban men changed more rapidly, with an average annual increase of 3.57%. The age effect on the morbidity and mortality of pancreatic cancer increased with age, and the effect was most obvious in age group 70-80 years, the period effect increased over time and the cohort effect decreased with year, but rebound or fluctuation was observed after 1976. Conclusions: The morbidity rate and mortality rate of pancreatic cancer in China increased slightly in past decades. Strategies on effective prevention and control of pancreatic cancer should be developed in the future.

Abstract
BACKGROUND Recent research suggests that although prokinetic agents, acid suppressors, and radical treatment for Helicobacter pylori infection may be effective in patients with functional dyspepsia (FD), a large proportion of patients still fail to respond to these treatments or may suffer from severe adverse reactions. Many traditional Chinese medicinal herbs can regulate the status of the entire body and have special advantages in the treatment of functional diseases. The present study was designed to verify the efficacy of Biling Weitong Granules (BLWTG), a traditional Chinese medicinal herbal compound formula, in alleviating epigastric pain syndrome (EPS) in FD patients, in an attempt to provide an effective prescription for the clinical treatment of this disease. AIM To evaluate the clinical efficacy and safety of BLWTG in treating EPS in patients with FD. METHODS In this multicenter, stratified, randomized, double-blind, placebo-controlled, parallel group clinical trial, eligible patients were randomized into the BLWTG and placebo groups who were treated for 6 wk. Efficacy indicators including the severity and frequency of EPS and the time to pain resolution and safety indicators including adverse events were observed and compared. RESULTS The baseline demographic data and clinical characteristics, such as epigastric pain symptoms, pain intensity, and frequency of attacks, were matched between the two groups before randomization. After 6 wk of treatment and after the center effect was eliminated, the epigastric pain was significantly improved in 28.33% and 85.59% of the patients in the placebo and BLWTG groups, respectively (P < 0.05). At 6 wk, the resolution rate of epigastric pain was 15% and 69.49% in the placebo and BLWTG groups, respectively (P < 0.05). The differences of total FD clinical score between these two groups were significant (P < 0.05) at 2, 4, and 6 wk (P < 0.05). The scores of each item and the total score in the Functional Digestive Disorders Quality of Life Questionnaire showed significant differences between the two groups at 6 wk after both the center and interaction effects were eliminated (P < 0.05). There was no significant difference in the incidence of adverse events between the two groups, and no serious adverse event was noted during the observation. CONCLUSION Compared with placebo, BLWTG markedly improved EPS in FD patients without causing serious adverse reactions.

METHODS Ten out of 85 SD rats were randomly selected as the sham group (n10), and 75 rats were developed a reflux esophagitis model (RE) by the esophageal and duodenal side-to-side anastomosis. Fifty successful modeling rats were divided into different medicated groups through a random number table including the model, low-, medium-, and high-dose of Tojapride as well as omeprazole groups (n10). Three doses of Tojapride [5.73, 11.46, 22.92 g/(kg•d)] and omeprazole [4.17 mg/(kg•d)] were administrated intragastrically twice daily for 3 weeks. And the rats in the sham and model groups were administered 10 mL/kg distilled water. Gastric fluid was collected and the supernatant was kept to measure for volume, pH value and acidity. Esophageal tissues were isolated to monitor the morphological changes through hematoxylin-eosin (HE) staining, and esophageal epithelial ultrastructure was observed by transmission electron microscopy. The expressions of nuclear factor kappa-light-chain-enhancer of activated B cells p65 (NF-KBp65), κB kinase beta (IKKß), occludin, and zonula occludens-1 (ZO-1) in the esophageal tissues were measured by immunohistochemistry and Western blot, respectively. RESULTS The gastric pH value in the model group was significantly lower than the sham group (P<0.05). Compared with the model group, gastric pH value in the omeprazole and medium-dose of Tojapride groups were significantly higher (P<0.05). A large area of ulceration was found on the esophageal mucosa from the model rats, while varying degrees of congestion and partially visible erosion was observed in the remaining groups. Remarkable increase in cell gap width and decrease in desmosome count was seen in RE rats and the effect was reversed by Tojapride treatment. Compared with the sham group, the IKKß levels were significantly higher in the model group (P<0.05). However, the IKKß levels were down-regulated after treatment by all doses of Tojapride (P<0.01 or P<0.05). The occluding and ZO-1 levels decreased in the model group compared with the sham group (Ps0.01 or Ps0.05), while both indices were significantly up-regulated in the Tojapride-treated groups (P<0.01 or P<0.05). CONCLUSIONS Tojapride could improve the pathological conditions of esophageal epithelium in RE rats. The underlying mechanisms may involve in down-regulating the IKKß expression and elevating ZO-1 and occludin expression, thereby alleviating the inflammation of the esophagus and strengthening the barrier function of the esophageal epithelium.

Abstract
Objective: This study was designed to investigate prognostic factors and the potential relationship between the expression of Ki67 and IDH of glioblastoma in the elderly (≥ 65 years old) and the clinical factors such as gender, the KPS score and treatments including surgical resection, radiotherapy and chemotherapy and the prognosis of such patients. Methods: Fifty-four elderly patients (≥ 65 years old) with glioblastoma admitted to the First Affiliated Hospital of Zhengzhou University from 2013 to 2018 were enrolled in this study. The expression of Ki67 was detected by immunohistochemical SP method and the mutation of IDH was detected by Sanger sequencing. Finally, statistical analysis was performed to determine whether Ki67, the mutation of IDH, gender, the KPS score and the extent of resection, radiotherapy and chemotherapy were associated with the clinical prognosis of the patients. Results: Of the 54 elderly patients with glioblastoma, none was detected with IDH mutation. Univariate analysis showed that Ki67(P=0.033), the KPS score (P=0.008), the extent of resection (P<0.001) were factors influencing the prognosis of elderly patients with glioblastoma. Patients receiving postoperative adjuvant radiotherapy (P=0.002) and chemotherapy (P=0.034) had longer survival time. There was no significant correlation between gender (P=0.467) and prognosis. Multivariate analysis demonstrated that radiotherapy (OR 2.446, P=0.009) and the extent of resection (OR 6.976, P<0.001) were independent prognostic factors. Conclusions: No IDH mutation was detected in all the patients in this study, indicating that IDH mutation is indeed rare in elderly glioblastoma, which suggests that geriatric population often harbor a molecular phenotype with poor prognosis. Ki67, KPS score, the extent of resection, radiotherapy and chemotherapy were the factors influencing the prognosis of patients.

Abstract
A passive and noninvasive diagnostic system based on high-frequency B-dot probes (HFBs) has been designed and developed for the measurement and identification of ion cyclotron emission (ICE) in the Experimental Advanced Superconducting Tokamak (EAST). Details of the hardware components of this system including HFBs, direct current blockers, radio frequency splitters, filters, and power detectors as well as data acquisition systems are presented. A spectrum analyzer is used in addition to the ordinary speed acquisition card for data registration and analysis. The reliability of a HFB based diagnostic system has been well validated during the 2018 spring experiments on the EAST. ICE signals corresponding to fundamental cyclotron frequency of hydrogen ions and harmonics of deuterium ions were observed in experiments where deuterium plasmas were heated with deuterium neutral beams. The field dependence of ICE has been verified by recent experiments with three different background magnetic fields. The observed ratio of the ICE frequency is consistent with the ratio of the magnetic field intensity within measurement errors of a few percent.

Abstract
Experiments involving scanning electron microscopy of the microstructure of barbules and optical microscopy of knotted barbules were conducted: the behaviour of knotted barbules, and their evolution to form a branch of hooked barbules and unhooked barbules were analysed. A growth model for a feather plume was proposed. MATLAB™ 2-d contour microstructures of sectioned knotted feathers and three-dimensional structural models of barbules were established, moreover, these were analysed using the finite element method. The response under load of different parts of the barbules was obtained. The results showed that there were stress concentrations in feather barbules. The study laid a foundation for finding the internal and external causes of the evolutionary transition of knotted barbules.

Abstract
Objiective: To evaluate the prognosis of visual function and the impact of surgery in pediatric patients with sellar mass lesions, as evidenced by diffusion tensor imaging (DTI) and visual evoked potentials. Methods: Twenty patients with sellar mass lesions were included in the study. DTI and visual evoked potentials were obtained before and after surgery. Fractional anisotropy (FA) and apparent diffusion coefficient (ADC) values were calculated for both optic nerves. DTI parameters and visual evoked potential amplitudes were compared for all patients to assess the correlation between DTI parameters and visual function. Results: The 20 patients were divided into two groups according the relationship between the lesions and the optic chiasm. The FA values increased significantly after operation, while the ADC values decreased (P<0.05). And the average amplitude of visual evoked potentials after operation was significantly higher than before operation (P<0.05). Conclusions: DTI assessments of the affected sides, with the resulting FA and ADC values, may help to estimate the visual improvement produced by surgical therapy in the early postoperative period. Surgical removal can improve visual function dramatically.

Abstract
Objective: To investigate the value of fibrinogen to albumin ratio (FAR) at admission on predicting spontaneous recanalization of infarct-related artery (IRA) in patients with acute ST-segment elevation myocardial infarction (STEMI). Methods: Clinical data from 255 acute STEMI patients ((61.1±11.2) years old, 189 males) who underwent emergency coronary angiography within 12 hours in our hospital from December 2015 to April 2018 were retrospectively analyzed. The acute STEMI patients were divided into non-spontaneous recanalization group (thrombolysis in myocardial infarction (TIMI) flow grade 0-1, 203 cases) and spontaneous recanalization group (TIMI flow grade 2-3, 52 cases). Multivariate logistic regression analysis was used to evaluate related factors of IRA spontaneous recanalization. The receiver operating characteristic (ROC) curve was used to evaluate the value of FAR in predicting spontaneous coronary recanalization. Results: There was no significant difference in age,gender, hypertension, diabetes, smoking,systolic blood pressure,diastolic blood pressure,heart rate, duration of chest pain, type of infarction, infarct-related artery, door-to-balloon time, and drug used before admission between non-spontaneous recanalization group and spontaneous recanalization group (all P>0.05). The FAR and high-sensitivity C-reactive protein levels were significantly lower in the spontaneous recanalization group than in the non-spontaneous recanalization group (8.20±1.85 vs. 11.02±2.75, P<0.001; (6.87±3.36) g/L vs. (8.51±3.72) g/L, P=0.004). Multivariate logistic regression analysis showed that FAR (OR=0.492, 95%CI 0.354-0.686, P<0.001), serum uric acid (OR=0.994, 95%CI 0.989-0.999, P=0.018) and high-sensitivity C-reactive protein (OR=0.774, 95%CI 0.614-0.975, P=0.030) were independent negative correlation with spontaneous recanalization of infarct-related artery in patients with acute STEMI. The ROC curve showed that the area under the curve of FAR predicting spontaneous recanalization of infarct-related artery in patients with acute STEMI was 0.807 (95%CI 0.630-0.758, P<0.001), and the diagnostic threshold was 9.26, the sensitivity was 76.9%, the specificity was 75.9%. Conclusion: The level of admission FAR has certain predictive value for spontaneous recanalization of infarct-related arteries in patients with acute STEMI.

Abstract
Objective: To compare the effects of different hemolytic diseases on the level of glycosylated hemoglobin (HbA(1c)) to further explore the relationship between HbA(1c) and laboratory indexes to disclose implications of HbA(1c) in hemolytic diseases. Methods: The distribution of 192 decreased HbA(1c) cases in 4 categories of hemolytic diseases was analyzed. Laboratory indexes related to hemolysis were tested and analyzed in each kind of disease, and relationship between laboratory indexes and HbA(1)c was statistically explored. Results: Diagnoses of decreased HbA(1c) cases mainly included erythrocyte membranopathies (88 cases), immunohemolytic anemia (72 cases), hemoglobinopathy (4 cases) and erythrocyte enzymopathy (5 cases). The distribution of HbA(2) and normal HbF subjects in immunohemolytic anemia and hemoglobinopathy was significantly different from those of HbA(2) and / or abnormal HbF subjects (41.7% vs 22.0%, χ(2)=5.574, P=0.018; 0.7% vs 7.3%, P=0.031). Compared with non-hemolytic disease patients, those who suffered from 4 categories of hemolytic diseases showed lower HbA(1c) level and higher reticulocyte percentage (Ret), indirect bilirubin (IBIL) and free hemoglobin (F-Hb). Different levels of Ret, reticulocyte hemoglobin content (Ret-He), mean corpuscular volume (MCV), IBIL and F-Hb among the 4 kinds of diseases were observed, but the causes of the differences were not the same. HbA(1c) was negatively correlated with other laboratory indexes in erythrocyte membranopathies and immunohemolytic anemia. Conclusions: Hemolytic disease resulted in false lower HbA(1c), but impact of difference on HbA1c between different diseases was not significant. HbA(1c) was closely connected to laboratory indexes related to hemolysis, which might have potential implications for hemolytic diseases such as erythrocyte membranopathies and immunohemolytic anemia.

Abstract
BACKGROUND Alstonia scholaris (Apocynaceae) was reported to be a rich source of indole alkaloids, which exhibited remarkably bioactivities. The leaf of A. scholaris has been used in 'dai' ethno-medicine for treatment of respiratory diseases, and the defined indole alkaloids from leaf of A. scholaris has been registered as investigational new botanical drug (No. 2011L01436) and was approved for phase I/II clinical trials by China Food and Drug Administration (CFDA). PURPOSE The aim of the trial is to evaluate the safety and explore the relationship of dosing frequency and pharmacokinetics after oral administration of capsule of alkaloids from leaf of A. scholaris (CALAS) at different doses. METHODS In this randomized, open-labelled, single-center clinical trial, the safety and pharmacokinetics of CALAS were assessed in eligible healthy Chinese volunteers after oral administration of different doses. Each volunteer (n = 10 per group) received single dose of CALAS from 20 mg, 40 mg, 80 mg to 120 mg orally. The pharmacokinetics of CALAS was investigated in healthy Chinese subjects' plasma by a fully-validated LC-MS/MS method. Safety was assessed biochemically and clinically throughout the study, and drug re-excitation research was conducted to verify the correlation between investigational product and minor adverse events. The trial was registered on August 26, 2015 (http://www.chictr.org.cn/showproj.aspx?proj=11736), number ChiCTR-IPR-15006976. RESULTS 40 subjects completed the study, and as a result, vallesamine had the highest concentration in plasma of healthy volunteers, and the AUC exposure level in each compounds in turn is vallesamine > scholaricine > 19-epischolaricine > picrinine. For the safety evaluation of CALAS, two cases of minor adverse events were observed during the trial, but the drug re-excitation research indicated that these two adverse events were related to the individual's physiological variation. CONCLUSION Pharmacokinetic characteristics of each ingredient showed different patterns. 19-epischolaricine, vallesamine and picrinine were match to the linear pharmacokinetic characteristics, but scholaricine conformed to the characteristics of nonlinear pharmacokinetics. The CALAS was safe in healthy subjects under the current dose regimen.

Abstract
Pancreatic cancer has poor prognosis and lymph node metastasis is a poor prognostic factor in patients with resectable pancreatic cancer. The metastatic prevalence of para-aortic lymph node (PALN) ranges from 9.1% to 26.5% and it is listed as the distant metastatic group in pancreatic cancer. Nevertheless, it is controversial whether PALN metastasis is the contraindication of surgery in resectable pancreatic cancer for the shortage of level Ⅰ evidence.This study concluded that PALN metastasis indicated poor prognosis in patients with pancreatic cancer, but some patients with PALN metastases could benefit from surgery and their survival could be much improved after the combination of surgery and adjuvant therapy. Therefore, it is not wise to refuse surgery for all pancreatic cancer patients with PALN metastasis and the clinicians can cautiously choose the patients to do surgery. Besides, there are mainly retrospective studies rather than prospective and multicenter studies to explore the prognosis of pancreatic cancer patients with PALN metastasis. Thus, more prospective and multicenter studies are needed to decide whether PALN metastasis is an independent prognostic factor in patients with resectable pancreatic cancer.
