Abstract
Three undescribed cassane diterpenoids, caesalpanins D-F (1-3), and seven known ones were isolated from the seeds of Caesalpinia sappan. Structures and absolute configurations of 1-3 were elucidated based on the extensive spectroscopic analysis, single-crystal X-ray diffraction analysis, and ECD calculations. Structurally, compound 1 was the first example of 18-norcassane diterpenoid and 2 was a rare 20-norcassane diterpenoid having an unusual five-membered oxygen bridge between C-10/C-18. The anti-proliferative activity of 1, 3, and 4-10 against PANC-1 cells (pancreatic ductal adenocarcinoma cell line) was evaluated, and phanginin H (4) was found to exhibit anti-cancer activity with IC50 value of 18.13 ± 0.63 μM. Compound 4 inhibited PANC-1 cell growth by arresting the cell cycle at G2/M phase via regulation of cyclin-dependent kinases, and the self-renewal and metastasis of PANC-1 cells by suppressing cancer cell stemness. Furthermore, compound 4 induced ROS generation and subsequently activated autophagy, which was demonstrated by the formation of autophagic vacuoles and dynamic change of autophagic flux. The induced ROS accumulation resulted in AMPK activation and subsequently regulation of mTORC1 activity and ULK phosphorylation, indicating that 4 triggered autophagy through ROS/AMPK/mTORC1 pathway. These findings suggested that 4 might potentially be an autophagy inducer for the therapy of pancreatic cancer.

Abstract
By systematically examing through Longdan Xiegan Decoction in medical books of the past dynasties, it was found that the Longdan Xiegan Decoction recorded in Lan Shi Mi Cang mainly targeted men's genital odor at frist. After Xue Ji's addition and subtraction, the scope of the prescription was gradually generalized and expanded, and confusion its name, composition and source of the prescription appeared, which was particularly prominent in Jingyue Quanshu and Yifang Jijie.Doctors used to interpret this prescription from the perspective of viscera. In order to better understand the main treatment rules of Longdan Xiegan Decoction, it is necessary to change the perspective and reinterpreted it from the perspective of meridians.Attributing the symptoms of the perineum to Liver Meridian of Foot-Jueyin,hypochondriac pain, deafness and other symptoms to the Gallbladder Meridian of Foot-Shaoyang, and adding or subtracting herbs according to the specific conditions, is not only conducive to a comprehensive and in-depth understanding of the prescription to achieve accurate clinical syndrome differentiation and medication, but also prompts modern researchers to rethink the important role of meridian theory in the formation and development of the theoretical system of traditional Chinese medicine.

Abstract
Five undescribed eudesmane sesquiterpenoids, artemilavanins A-E, and one undescribed rearranged eudesmane sesquiterpenoid, artemilavanin F, were isolated from the 95% ethanol extract of the aerial parts of Artemisia lavandulaefolia DC., along with ten known compounds. The structures and configurations of undescribed compounds were mainly elucidated by spectroscopic analyses and single-crystal X-ray diffraction analysis. Among all isolated compounds, artemilavanin F exhibited inhibitory activity on PANC-1 pancreatic cancer cells with IC50 of 9.69 ± 2.39 μM. Artemilavanin F inhibited PANC-1 cell proliferation by induction of G2/M cell cycle arrest and apoptosis mediated by downregulation of cyclin-dependent kinases and accumulation of reactive oxygen species. Moreover, artemilavanin F inhibited the colony formation, cell migration and sphere formation of PANC-1 cells, indicating the suppression of stem-cell-like phenotype of PANC-1 cells. Further results confirmed that the expression of cancer stem cell markers such as Bmi1, CD44, CD133 were inhibited by artemilavanin F. Downregulation of epithelial-mesenchymal transition (EMT) markers such as N-cadherin and Oct-4 indicated the potential of artemilavanin F in prevention of metastasis.

Abstract
Renin-angiotensin system (RAS) plays an indispensable role in regulating blood pressure through its effects on fluid and electrolyte balance. As an aside, cumulative evidence from experimental to clinical studies supports the notion that dysregulation of RAS contributes to the pro-inflammatory, pro-oxidative, and pro-fibrotic processes that occur in pulmonary diseases like asthma, chronic obstructive pulmonary disease (COPD), idiopathic pulmonary fibrosis (IPF), and acute lung injury (ALI). Pharmacological intervention of the various RAS components can be a novel therapeutic strategy for the treatment of these respiratory diseases. In this chapter, we first give a recent update on the RAS, and then compile, review, and analyse recent reports on targeting RAS components as treatments for respiratory diseases. Inhibition of the pro-inflammatory renin, angiotensin-converting enzyme (ACE), angiotensin (Ang) II, and Ang II type 1 receptor (AT1R) axis, and activation of the protective ACE2, AT2R, Ang (1-7), and Mas receptor axis have demonstrated varying degrees of efficacies in experimental respiratory disease models or in human trials. The newly identified alamandine/Mas-related G-protein-coupled receptor member D pathway has shown some therapeutic promise as well. However, our understanding of the RAS ligand-and-receptor interactions is still inconclusive, and the modes of action and signaling cascade mediating the newly identified RAS receptors remain to be better characterized. Clinical data are obviously lacking behind the promising pre-clinical findings of certain well-established molecules targeting at different pathways of the RAS in respiratory diseases. Translational human studies should be the focus for RAS drug development in lung diseases in the next decade.

Abstract
Objective: To investigate the application of vaseline gauze to occlude the bronchial fistulas and its clinical effectiveness and safety in this retrospective study. Methods: This study retrospectively reviewed the clinical records of 14 patients with bronchial fistulas at Department of Respiratory and Critical Care Medicine, Shanghai Dongfang Hospital affiliated to Tongji University between June 2019 and June 2022. Seven of the 14 patients were female, and the age ranged from 16 to 74 years. We retrieved all the clinical records of all the enrolled patients during the 6 to 12 months follow-up after the operation, including the information for removal of chest drainage pipe, the failure of endobronchial blockage using vaseline gauze, as well as the complications (migration of the vaseline gauze, obstructive pneumonia, pulmonary atelectasis, et. al.) after the operation. Results: Of the 14 patients, 3 patients had fistula located in main or lobar bronchi; 10 patients had fistula located in distal airways; and 1 patient had fistula located both in main bronchi and distal airways. Ten patients were complicated with pneumonia or pleural cavity infections; Five were complicated with pneumothorax or hydropneumothorax. All of the 14 patients achieved successful airway occlusion after the placement of vaseline gauze in the responsible bronchial airways or stumps for the fistulas. Eleven of the 14 patients successfully removed the drainage tube for the residual cavity, 3 of the 14 patients successfully removed the vaseline gauze for the fistula which was healing during the follow up of 6-12 months. No one of the patients had severe complications or treatment failure. Conclusion: Bronchial placement of vaseline gauze might be a feasible and effective technique for treatment of bronchial fistulas.

Abstract
Four highly oxygenated sesquiterpenoids, illimicranolides A (1) and B (2), and illicinolides E (3) and F (4), were obtained from the fruits of Illicium micranthum Dunn, as well as one known analog, illicinolide B (5). The chemical structures of 1-4 were determined comprehensively by 1D (1 H and 13 C) and 2D (HMBC, HSQC, 1 H-1 H COSY, and ROESY) NMR, and HR-ESI-MS data. Structurally, compound 1 was an unprecedented sesquiterpenoid with a 5/5/6/5-fused tetracyclic ring system and was the first seco-prezizaane sesquiterpenoid featuring a 11,8-γ-lactone ring. Compounds 3 and 4 were the fifth and sixth examples of illicinolide-type sesquiterpenoids. Moreover, compound 1 demonstrated neurotrophic activity of NGF-induced PC12 cells with differentiation rate of 10.34 % at a concentration of 10 μM.

Abstract
Five new fawcettimine-type Lycopodium alkaloids, hupertimines A-E (1-5), were discovered from the whole plant of Huperzia serrata, along with two known alkaloids, 8α-hydroxyphlegmariurine B (6) and 8β-hydroxyphlegmariurine B (7). The structures of 1-7 were identified through HR-MS, IR, 1 H, 13 C, and 2D NMR, and single-crystal X-ray diffraction analysis. Structurally, compound 1 was the fourth example of Lycopodium alkaloid with an ether linkage between C-5 and C-13 and 2 was the third example of Lycopodium alkaloid with a 5/5/5/5/6 pentacyclic ring system and featuring a 1-aza-7-oxabicyclo[2.2.1]heptane unit. Compounds 1-7 were tested for their BACE1 inhibitory activity. In addition, the correct 1 H- and 13 C-NMR data for 7 were reported in current study.

Abstract
Ten previously undescribed cassane diterpenoids, cassabonducins A-J, and eleven known compounds were isolated from the seeds of Caesalpinia bonduc. The structures of the undescribed compounds were elucidated by extensive analysis of spectroscopic data (IR, HRESIMS, and 1H, 13C and 2D NMR) and their absolute configurations were determined by the ECD data and single-crystal X-ray diffraction analysis. ε-Caesalpin-Ⅶ was obtained from natural resources for the first time. Cassabonducin A possessed noteworthy inhibitory activity against LPS-induced nitric oxide (NO) production in RAW 264.7 macrophages with IC50 value of 6.12 μM. Cassabonducin D and neocaesalpin N showed moderate α-glucosidase inhibition at the concentration of 50 μM with inhibitory capacities of 47.17% and 43.83%, respectively.

Abstract
A new neo-clerodane diterpenoid, salvihispin H (1), and six known ones (2-7) were identified from the aerial parts of Salvia hispanica L. The structure and absolute configuration of 1 were elucidated by extensive analysis of spectroscopic (1 H, 13 C, and 2D NMR, and HR-ESI-MS) and single-crystal X-ray diffraction data. The anti-diabetic effects of salvihispin H (1) and salvifaricin (2) were evaluated in diabetic db/db mice. The data showed that 1 and 2 could significantly reduce fasting blood glucose level and improve insulin resistance, and compound 1 exerted glucose-lowering effect more quickly than metformin. In addition, 1 and 2 could also reduce serum TG level in db/db mice. These results demonstrated that compounds 1 and 2 could be considered as potent candidates for the therapy of type 2 diabetes mellitus (T2DM).

Abstract
Objective: To provide a portable electroencephalograph that can facilitate long-term monitoring of epilepsy patients outside the hospital, and establish a medical platform for epilepsy data monitoring and treatment. Methods: From June 2018 to October 2019, twenty-nine patients from Huashan Hospital (superior hospital) and Jing'an District Central Hospital (subordinate hospital) of Fudan University were enrolled in the study. Among them, twenty-eight cases were diagnosed with epilepsy and 1 case was epileptic seizure. Electroencephalogram (EEG) was collected by portable electroencephalograph once a week and followed up for three months. The seizure frequency, seizure form, medication type, EEG lead number and positive rate were recorded. Patients' medical records and EEG data were uploaded to the cloud database to build a medical alliance platform. Doctors of different levels of hospitals couldobtain diagnosis and achieve resource sharing based on the platform. The data was statistically analyzed using SPSS 18.0. Results: The EEG data collected by the portable electroencephalograph hadfewer artifacts, complete sleep cycle, and could record the interictaldischarges. Twenty-nine patientsunderwent a total of 148 EEG monitoring during the three-month follow-up. Eighty-five cases of epileptic discharges were detected, and the EEG positive rate was 57.4%. The positive rate of EEG in patients with generalized seizures (84.9%) was higher than that in patients with focal seizures (42.1%) (P<0.01); the positive rate of EEG in patients with 2-3 antiepileptic drugs and patients with frequent seizures within three months were also higher (P<0.05). Doctors in the superior hospital in the platform make diagnosis and treatment suggestions according to the above data. Elevenseizure-free patients and four patients with fewer seizures and discharges were diverted to the community hospital for follow-up. Fourteen patients with poor seizure control and/or continuous epileptic discharges were diverted to the superior hospitalto adjust the medication. Doctors of subordinate hospital acquired the diagnosis and treatment suggestions through the platform, and then strengthened the daily care and follow-up. Conclusion: Combined with a portable electroencephalograph, the current study establishs a medical platform for patients with epilepsy to achieve long-term monitoring and rational use of medical resources.

Abstract
Flax seed meal (FSM) is rich in various nutrients, especially CP and energy, and can be used as animal protein feed. In animal husbandry production, it is a long-term goal to replace soybean meal (SBM) in animal feed with other plant protein feed. However, studies on the effects of replacing SBM with FSM in fattening sheep are limited. The aim of this experiment was to study the effects of replacing a portion of SBM with FSM on nutrient digestibility, rumen microbial protein synthesis and growth performance in sheep. Thirty-six Dorper × Small Thin-Tailed crossbred rams (BW = 40.4 ± 1.73 kg, mean ± SD) were randomly assigned into four groups. The dietary treatments (forage/concentrate, 45 : 55) were isocaloric according to the nutrient requirements of rams. Soybean meal was replaced with FSM at different levels (DM basis): (1) 18% SBM (18SBM), (2) 12% SBM and 6% FSM (6FSM), (3) 6% SBM and 12% FSM (12FSM) and (4) 18% FSM (18FSM). The rams were fed in individual pens for 60 days, with the first 10 days for adaptation to diets, and then the digestibility of nutrients was determined. There was no significant difference in DM intake, but quadratic (P < 0.001) effects on the average daily gain and feed efficiency were detected, with the highest values in the 6FSM and 12FSM groups. For DM and NDF digestibility, quadratic effects were observed with the higher values in the 6FSM and 12FSM groups, but the digestibility of CP linearly decreased with the increase in FSM in the diet (P = 0.043). There was a quadratic (P < 0.001) effect of FSM inclusion rate on the estimated microbial CP yield. However, the values of intestinally absorbable dietary protein decreased linearly (P < 0.001). For the supply of metabolisable protein, both the linear (P = 0.001) and quadratic (P = 0.044) effects were observed with the lowest value in the 18FSM group. Overall, the results indicated that SBM can be effectively replaced by FSM in the diets of fattening sheep and the optimal proportion was 12.0% under the conditions of this experiment.

Abstract
By differentiating intermediate trade from final trade, this paper combines typical statistics for the world economy in 2012 to explore the transfer of embodied carbon emissions via the global supply chain and the related trade imbalance. The emission transfer embodied in interregional trade is in magnitude around 40% of global direct carbon emissions. The global intermediate trade volume of embodied carbon emissions is estimated to be 2.3 times as much as the final trade volume. While Mainland China obtains a considerable economic trade surplus, its carbon trade deficit is about twice the carbon trade surplus of the United States. Mainland China's final trade deficit is around 1.2 times as much as its intermediate trade deficit of embodied carbon emissions. EU27, the United States, ASEAN and Japan serve as the major contributors to China's intermediate and final trade deficits. For the United States, its intermediate carbon trade surplus is almost equal to its final trade surplus. The United States gains a carbon surplus with most of its trading partners in both intermediate and final trades. A future scenario analysis in terms of carbon emission projection is conducted. While the direct and embodied carbon emissions of the United States and Japan are estimated to change slightly from 2012 to 2040, India's carbon emissions are projected to experience a twofold increase during the period. In the long term, though with ups and downs, the economic globalization will be inevitably moving forward, leading to a highly sliced-up global supply chain and increasingly delicate regional specialization as well as frequent intermediate trade between regions. It is suggested that nations and regions should follow this trend and adapt themselves to the global value chain by carefully assessing their roles in intermediate and final trades in terms of both currency and embodied carbon emissions.

Abstract
A phytochemical study on the stem bark of Metasequoia glyptostroboides led to the isolation of sixty-one diterpenoids and sesquiterpenoids, including seventeen previously undescribed compounds, metaglyptins A-Q. Their structures were elucidated by extensive analysis of spectroscopic data (IR, UV, HRESIMS, and 1H, 13C and 2D NMR). The absolute configurations of metaglyptins I, J, and O were determined by the ECD data and single-crystal X-ray diffraction analysis. The undescribed compounds were evaluated for their cytotoxicity against HeLa, AGS, and MDA-MB-231 cancer cell lines. The results revealed that metaglyptin A exhibited moderate cytotoxicity against MDA-MB-231 cell line with IC50 value of 20.02 μM.

Abstract
Within a single integrated globalized economy featuring robust fluxes of interregional trades, the world economy is like a giant bathtub containing the world inventory of energy use. Based on different norms or ethic percepts, the energy use of the world economy is reallocated to nations and regions via global supply chain using normative accounting schemes. By combining typical statistics for world economy 2012, a new perspective is presented in this study to look into the energy use of regional economies from the side of genuine final consumers. Parallel to the final-demand-based accounting method, a total-consumption-based multi-region input-output accounting method is developed following the norm of consumption being the ultimate end and purpose of all producing activities. From a total-consumption-based perspective, the energy use of the United States economy is shown in magnitude 1.8 times that of mainland China, compared to a ratio of 88% from a territorial-based perspective. The consumer-product-related trade imbalances of major economies in terms of both currency and energy use are analyzed, with major interregional net trade flows illustrated. While the United States and mainland China are respectively revealed as the leading net exporter and net importer of currency, the energy trade deficit of the latter is in magnitude around four times the energy trade surplus of the former. The trade structures by geography and sector are respectively presented for the United States and mainland China as two distinct economies. It is found that around half of the United States' exports of energy use originate from transport and service industries, while nearly 90% of mainland China's exports of energy use come from heavy industry. The findings are supportive for nations to identify their roles in the global supply chain from the perspective of genuine final consumers and adjust the trade patterns for sustained energy use.

Abstract
Nine previously undescribed sesquiterpenoids, named magnograndins A-I, as well as fourteen known ones, were obtained from the 70% acetone extract of the leaves of Magnolia grandiflora. Their structures were ascertained based on the spectroscopic evidences. The assignment of the relative configuration of magnograndin A was further confirmed by single-crystal X-ray diffraction analysis. 1β,10α-Epoxyparthenolide, parthenolide, and micheliolide exhibited potent cytotoxic activity against MDA-MB-468, AGS, HCT116, Hela, and MDA-MB-231 human cancer cell lines with IC50 values ranging from 1.76 to 16.11 μM. 1β,10α-Epoxyparthenolide and micheliolide potently inhibited NF-κB transcriptional activity with IC50 of 13.92 and 8.95 μM, respectively. The expression levels of NF-κB downstream protein p65 and XIAP were clearly down-regulated in 1β,10α-epoxyparthenolide and micheliolide treated cells, which demonstrated the inhibition of NF-κB signaling pathway.

Abstract
Objective: To study the variations and influencing factors of serum triglycerides and cholesterol levels during pregnancy and postpartum. Methods: A retrospective study was performed among 5 020 healthy singleton (95.10%, 4 774/5 020) and twin (4.90%, 246/5 020) women who had delivery in Women's Hospital, Zhejiang University School of Medicine from January 2011 to December 2016. Serum triglycerides and cholesterol levels during pregnancy and postpartum of all the cases were collected. Both singleton and twin pregnant women were divided into advanced age and appropriate age groups, and then data of serum sample were assigned to 3 groups according to the gestation weeks, which were second trimester pregnancy (24-28 gestation weeks) , third trimester pregnancy (32-41 gestation weeks) and postpartum (within 72 hours after delivery) . The serum triglycerides and cholesterol levels in each groups were compared. Results: (1) Serum triglycerides and cholesterol levels during the second trimester pregnancy, third trimester pregnancy and postpartum were higher than levels of non-pregnancy in both singleton and twin groups (all P<0.05) . (2) Serum triglycerides and cholesterol levels in the third trimester pregnancy group were higher than those of second trimester pregnancy group in both advanced age and appropriate aged women regardless singleton or twin pregnancy (all P<0.05) . The 95%CI of serum lipid levels in each group during second and third trimester pregnancy were as follows: in appropriate aged singleton group, the triglycerides levels were 1.07-4.13 and 1.52-7.21 mmol/L, and the cholesterol levels were 2.77-12.11 and 4.44-9.36 mmol/L. In advanced aged singleton group, the triglycerides levels were 1.28-4.61 and 1.70-7.80 mmol/L, and the cholesterol levels were 4.35-8.40 and 4.46-9.35 mmol/L; in appropriate aged twin group, the triglycerides levels were 1.39-7.16 and 1.90-9.29 mmol/L, and the cholesterol levels were 4.99-12.16 and 4.52-10.07 mmol/L; in advanced aged twin group, the triglycerides levels were 1.61-5.32 and 1.94-9.29 mmol/L, and the cholesterol levels were 5.24-8.10 and 4.53-8.86 mmol/L. (3) Serum lipids levels rapidly decreased during postpartum compared to the third trimester pregnancy. The 95%CI of blood lipid levels in each group were as follows: in appropriate aged singleton group, the triglycerides level was 0.90-5.64 mmol/L and the cholesterol level was 4.70-8.52 mmol/L; in advanced aged singleton group, the triglycerides level was 0.87-5.43 mmol/L and the cholesterol level was 4.68-9.04 mmol/L; in appropriate aged twin group, the triglycerides level was 1.20-8.21 mmol/L and the cholesterol level was 4.66-8.45 mmol/L; in advanced aged twin group, the triglycerides level was 1.32-6.61 mmol/L, and the cholesterol level was 5.01-7.94 mmol/L. (4) Serum triglycerides and cholesterol levels in twin pregnant women were significantly higher than in singleton during the second trimester and third trimester pregnancy both in advanced age and appropriate age groups (all P<0.05) . During postpartum, there was no difference in serum lipid levels between the singleton and twin pregnant women in appropriate age group (triglycerides: P=0.982; cholesterol: P=0.759, respectively) . While the serum lipid levels in twin pregnant women were significantly higher than those of singleton women in advanced age group (triglycerides: P=0.000; cholesterol: P=0.000, respectively) . Conclusions: The standard of serum lipid levels of non-pregnant adults is not suitable for assessing that in pregnant women. Regardless of singleton or twin pregnancy, serum triglyceride and cholesterol levels during pregnancy elevate with the increasing gestational week and then rapidly decrease during postpartum. Age and twins are the influencing factors of the elevated physiological lipid levels during pregnancy.

Abstract
Activity-guided fractionation strategy was used to investigate chemical constituents from the roots of Podocarpus macrophyllus. Successfully, two new norditerpenes, 2β-hydroxymakilactone A (1) and 3β-hydroxymakilactone A (2), along with ten known analogues (3 - 12) were isolated. The structures of 1 and 2 were elucidated by spectroscopic analysis including 1D-, 2D-NMR, and HR-ESI-MS data. The previously reported structure of 2,3-dihydro-2α-hydroxypodolide was revised as 2,3-dihydro-2β-hydroxypodolide (3) by spectroscopic analysis, and was further confirmed by X-ray crystallographic analysis. Cytotoxic activities of all isolated compounds against five human solid tumour cell lines (AGS, HeLa, MDA-MB-231, HepG-2, and PANC-1) were evaluated. All of them exhibited anti-proliferative activities (IC50 = 0.3 - 27 μm), except for 10. Compounds 1, 4, 5, 6, and 8 exhibited potent inhibitory activities with IC50 < 1 μm against HeLa and AGS cells.
