The Practical Access to Fluoroalkylated Pyrazolo[1,5-c]quinazolines by Fluoroalkyl-Promoted [3 + 2] Cycloaddition Reaction.

The efficient synthesis of fluoroalkylated pyrazolo[1,5-c]quinazolines by reactions of 3-diazoindolin-2-ones with methyl ß-fluoroalkylpropionates has been achieved. This protocol affords two regioisomers of fluoroalkylated pyrazolo[1,5-c]quinazolines with excellent yields in total. The dipolarophilicity of methyl ß-fluoroalkylpropionates enhanced by perfluoroalkyl groups is crucial for the high efficiency of this [3 + 2] cycloaddition reaction.

Coherent optical control of a superconducting microwave cavity via electro-optical dynamical back-action.

Recent quantum technologies have established precise quantum control of various microscopic systems using electromagnetic waves. Interfaces based on cryogenic cavity electro-optic systems are particularly promising, due to the direct interaction between microwave and optical fields in the quantum regime. Quantum optical control of superconducting microwave circuits has been precluded so far due to the weak electro-optical coupling as well as quasi-particles induced by the pump laser. Here we report the coherent control of a superconducting microwave cavity using laser pulses in a multimode electro-optical device at millikelvin temperature with near-unity cooperativity. Both the stationary and instantaneous responses of the microwave and optical modes comply with the coherent electro-optical interaction, and reveal only minuscule amount of excess back-action with an unanticipated time delay. Our demonstration enables wide ranges of applications beyond quantum transductions, from squeezing and quantum non-demolition measurements of microwave fields, to entanglement generation and hybrid quantum networks.

Structure-activity relationship of Lycium barbarum polysaccharides / 中国中药杂志

As a traditional Chinese herb and functional food, the fruits of Lycium barbarum has been widely used for thousands of years in China. L. barbarum polysaccharides(LBPs) are predominant active components, which have immunomodulatory, antioxidant, hypoglycemic, neuroprotective, anti-tumor, and prebiotic activities. The molecular weight, monosaccharide composition, glycosidic bond, branching degree, protein content, chemical modification, and spatial structure of LBPs are closely related to their biological activity. Based on the previous studies of this research team, this paper systematically combed and integrated the research progress of structure, function, and structure-activity relationship of LBPs. At the same time, some problems restricting the clarification of the structure-activity relationship of LBPs were considered and prospected, hoping to provide references for the high value utilization of LBPs and in-depth exploration of their health value.

AIM: To investigate the effect of modified Chufeng Yisun Decoction on ocular surface inflammation after pterygium surgery.METHODS: A total of 60 patients(60 eyes)with primary pterygium who underwent pterygium surgery were randomly divided into control group and study group, with 30 cases(30 eyes)in each group. In the control group, patients were treated with pranoprofen eye drops, tobramycin dexamethasone eye drops, and deproteinized calf blood extract eye gel after the surgery. In the study group, patients were treated by oral modified Chufeng Yisun Decoction in addition to the treatments in the control group. The changes of ocular irritation symptoms, ocular inflammatory signs, tear interleukin 6(IL-6)levels, and tear ferning test(TFT)of patients in the two groups were assessed.RESULTS: The visual analogue scale(VAS)in patients of both groups was significantly lower at 2d and 1wk after the surgery than that at 1d after the surgery(all P<0.01), and the VAS of the study group was significantly better than that of the control group at 2d and 1wk after surgery(P<0.01). The ocular signs integrals(OSI)and TFT results of both groups at 1wk were significantly lower than those at 1d after the surgery(all P<0.01), and the OSI and TFT were also lower in the study group than in the control group at 1wk after the surgery(all P<0.01). In addition, the concentration of tear IL-6 in both groups was significantly lower at 1wk after the surgery than 1d after the surgery(all P<0.01), and it was also significantly lower in the study group than in the control group at 1wk after the surgery(P<0.05).CONCLUSION: The combination of Chufeng Yisun Decoction and conventional treatment of western has a better effect on controlling ocular surface inflammation after pterygium surgery.

TFA-Promoted Intermolecular Friedel-Crafts Alkylation of Arenes with 2,2,2-Trifluoroethylaryl Sulfoxides.

The classical Pummerer rearrangement of 2,2,2-trifluoroethylaryl sulfoxide with trifluoracetic anhydride (TFAA) affords the S,O-acetal efficiently. In the presence of trifluoracetic acid (TFA) as the co-solvent, the S,O-acetal can regenerate reactive thionium intermediate of Pummerer rearrangement. When employing arenes as nucleophiles, this strategy produces corresponding 1-thiyl-2,2,2-trifluoroethyl arenes with excellent yields under metal-free conditions.

Quantum-enabled operation of a microwave-optical interface.

Solid-state microwave systems offer strong interactions for fast quantum logic and sensing but photons at telecom wavelength are the ideal choice for high-density low-loss quantum interconnects. A general-purpose interface that can make use of single photon effects requires < 1 input noise quanta, which has remained elusive due to either low efficiency or pump induced heating. Here we demonstrate coherent electro-optic modulation on nanosecond-timescales with only [Formula: see text] microwave input noise photons with a total bidirectional transduction efficiency of 8.7% (or up to 15% with [Formula: see text]), as required for near-term heralded quantum network protocols. The use of short and high-power optical pump pulses also enables near-unity cooperativity of the electro-optic interaction leading to an internal pure conversion efficiency of up to 99.5%. Together with the low mode occupancy this provides evidence for electro-optic laser cooling and vacuum amplification as predicted a decade ago.

Analysis on incidence trend of liver cancer in China, 2005-2016 / 中华流行病学杂志

Objective: To understand the incidence trend of liver cancer in China from 2005 to 2016, and explore the correlation between the incidence trend of liver cancer and the incidence trend of hepatitis B. Methods: The incidence data of liver cancer in China from 2005 to 2016 were collected from the Annual Report of Cancer Registry in China. The incidence data of hepatitis B were collected from China Public Health Science Data Center. World standardized incidence rate (WSR) was calculated according to the World Segi's population. Joinpoint regression model was used to analyze the trend of WSR of liver cancer [measured by average annual percentage change (AAPC)]. The age-period-cohort model was fitted to analyze the age, period and cohort effects in people aged 20- years and above. Pearson correlation coefficient was used to explore the correlation between the incidence of liver cancer and the incidence of hepatitis B. Results: The crude incidence of liver cancer in China showed a trend of first increase before 2009 and then relatively stable. The world standardized morbidity rate of liver cancer in China decreased from 19.11 per 100 000 in 2005 to 17.74 per 100 000 in 2016 (AAPC=-0.5%, 95%CI: -1.3%-0.3%, P=0.240). The incidence of liver cancer in male decreased significantly (AAPC=-1.0%, 95%CI: -1.5%--0.5%, P=0.001). The incidence of liver cancer in women increased from 2005 to 2010 [annual percentage change (APC)=1.7%, 95%CI: -0.1%-3.4%, P=0.059] but showed a significant decrease trend from 2010 to 2016 (APC=-1.6%, 95%CI: -2.3%--1.0%, P=0.001). From 2005 to 2016, the incidence of liver cancer showed a decreasing trend in urban areas (AAPC=-0.3%, 95%CI: -0.8%-0.3%, P=0.316) and rural areas (AAPC=-3.9%, 95%CI: -4.4%--3.3%, P<0.001). Risk for liver cancer increased with age, while the period effect showed a trend of first increase then decrease and cohort effect showed a decrease trend. The morbidity rates of both hepatitis B and liver cancer showed decrease trends from 2009 to 2016, and there was a significant correlation (r=0.71, 95%CI: 0.01-0.94, P=0.048). Conclusions: From 2005 to 2016, the morbidity rate of liver cancer in China showed a decrease trend, and there were significant gender and urban-rural area specific differences. Age effect had a great impact on the risk for liver cancer. With the progress of population aging in China, liver cancer is still a public health problem, to which close attention needs to be paid.

Chemical Compositions and Anti-tumor Effect of Tetrastigma hemsleyanum： A Review / 中国实验方剂学杂志

Due to the infinite proliferation， strong migration and loss of contact inhibition of tumor cells， tumor has become the most intractable diseases to be cured in the world. At present， the main treatments of tumor diseases are surgical resection， radiotherapy， chemotherapy， targeted-therapy and immunotherapy. Although these measures can inhibit or kill the tumor to a certain extent， they still cannot avoid adverse reactions and drug resistance. After thousands of years of clinical practice， traditional Chinese medicine （TCM） has the characteristics of good curative effect， few adverse reactions and significantly improving the quality of life in patients， which provides new ideas for the prevention and treatment of tumors. As an endemic and rare plant in China， Tetrastigma hemsleyanum has been listed in the 2015 edition of Zhejiang Provincial Processing Specification of TCM with the effects of heat-clearing and detoxification， detumescence and analgesia， dissipating phlegm and resolving masses. It has been reported that the chemical constituents of T. hemsleyanum are mainly flavonoids， polysaccharides， phenolic acids， terpenoids， steroids， volatile oils， alkaloids and so on. It can exert a broad spectrum of anti-tumor effects through various ways such as inhibiting proliferation， migration and invasion of tumor cells， inducing apoptosis of tumor cells， inhibiting angiogenesis of tumor cells， reversing multidrug resistance of tumor cells and regulating body autoimmunity. On the basis of reviewing relevant literature at home and abroad， this paper intends to systematically sort out the chemical and anti-tumor research of T. hemsleyanum， and in order to provide a new idea for its synergistic anti-tumor effect of multi-component， multi-pathway and multi-target， and finally provide theoretical basis for the research and development and clinical application of new anti-tumor drugs of T. hemsleyanum.

Two cardenolide glycosides from the seed fairs of Asclepias curassavica and their cytotoxic activities / 中国天然药物

Two cardenolide glycosides, corotoxigenin 3-O-[β-D-glucopyranosyl-(1→4)-6-deoxy-β-D-glucopyranoside] (1) and coroglaucigenin 3-O-[β-D-glucopyranosyl-(1→4)-6-deoxy-β-D-glucopyranoside] (2), were isolated from the seed fairs of Asclepias curassavica. The structures of 1-2 were determined based on the combination of the analysis of their MS, NMR spectroscopic data and acid hydrolysis. The inhibitory effects of compounds 1 and 2 on human colorectal carcinoma cells (HCT116), non-small cell lung carcinoma cells (A549) and hepatic cancer cells (SMMC-7721) were evaluated. The results showed that both compounds 1 and 2 significantly inhibited the viability, proliferation, and migration of A549, HCT116 and SMMC-7721 cells, suggesting that compounds 1 and 2 can be applied in the treatment of lung, colon and liver cancers in clinical practice. This study may not only provide a scientific basis for clarifying the active ingredients in A. curassavica, but also help to understand its antitumor activity, which can promote the application of A. curassavica in clinical treatment of various cancers.

Synergistic effect on biosynthesis of Panax notoginseng saponins by overexpressing a transcription factor PnbHLH and RNA interference of cycloartenol synthase gene / 中国中药杂志

This study cloned the transcription factor gene PnbHLH which held an open reading frame of 966 bp encoding 321 amino acids. This study constructed the overexpression vector of transcription factor PnbHLH of Panax notoginseng. The combination of PnbHLH overexpression and RNAi of the key enzyme gene PnCAS involved in the phytosterol biosynthesis was achieved in P. notoginseng cells, thus exploring the biosynthetic regulation of P. notoginseng saponins(PNS) by the synergistic effect of PnbHLH overexpression and PnCAS RNAi. The results showed that the PnbHLH transcription factor interacted with the promoters of key enzyme genes PnDS, PnSS and PnSE in the biosynthetic pathway of PNS, and then regulated the expression levels of key enzyme genes and affected the biosynthesis of saponins indirectly. Further study indicated that the synergistic effect of PnbHLH overexpression and PnCAS RNAi was a more effective approach to regulate the biosynthesis of saponins. Compared with the wild type and PnCAS RNAi cells of P. notoginseng, the contents of total saponins and monomeric saponins(Rd, Rb_1, Re, Rg_1 and R_1) were increased to some extent in the cell lines of PnbHLH overexpression and PnCAS RNAi. This indicated that the two ways of forward regulation and reverse regulation of saponin biosynthesis showed superposition effect. This study explored a more rational and efficient regulation strategy of PNS biosynthesis based on the advantages of multi-point regulation of transcription factors as well as the down-regulation of by-product synthesis of saponins.

Ginkgolide K inhibited neurovascular unit injury against oxygen-glucose deprivation and reperfusion by regulating hypoxia-inducible factor-1α pathway / 中国药理学通报

Aim To investigate the protective effects of ginkgolide K (GK) on neurovascular unit injured by ischemic stroke and the potential mechanism associated with hypoxia-inducible factor-1α (HIF-1α) pathway. Methods The BV-2 cells and EA. hy926 cells suffered from oxygen-glucose deprivation and reperfusion (OGD/R) were applied to mimic the injury of neurovascular unit induced by cerebral ischemia in vitro. After 4 h OGD insult, BV-2 cells and EA. hy926 cells received reperfusion and treated with GK. The levels of inflammatory cytokines in the supernatant of BV-2 cells were detected, while the protective effects of GK on EA. hy926 cells were also evaluated after GK administration for 24 h. The p-Akt and p-Erk expressions were examined by Western blot after 1 h of GK treatment, while HIF-1α was detected after 6 h of GK treatment. In addition, PI3K inhibitor LY294002 was applied to further verify the potential mechanisms underlying the beneficial effects of GK. The expressions of p-Akt after 1 h of GK treatment, and the protein levels of HIF-1α pathway after 6 h of GK treatment were also analyzed by Western blot. Results GK significantly inhibited the levels of TNF-α, IL-6 and IL-1β in supernatant of BV-2 cells injured by OGD/R, through increasing p-Akt and decreasing p-Erk expressions, and then affecting HIF-1α pathway. In addition, LY294002 reduced the regulatory effect of GK. Furthermore, GK significantly improved viability and inhibited the release of LDH in supernatant of EA. hy926 cells suffered from OGD/R, and up-regulated the expressions of p-Akt, HIF-1α, HO-1 and VEGF, while cleaved caspase-3/9 was inhibited. Conclusions GK exerts multi-effects on reducing neurovascular unit injury induced by ischemic stroke, and the potential mechanism might be associated with the different regulatory effects of HIF-1α in different cells.

Laser Cooling of a Nanomechanical Oscillator to Its Zero-Point Energy.

Optomechanical systems in the well-resolved-sideband regime are ideal for studying a myriad of quantum phenomena with mechanical systems, including backaction-evading measurements, mechanical squeezing, and nonclassical states generation. For these experiments, the mechanical oscillator should be prepared in its ground state, i.e., exhibit negligible residual excess motion compared to its zero-point motion. This can be achieved using the radiation pressure of laser light in the cavity by selectively driving the lower motional sideband, leading to sideband cooling. To date, the preparation of sideband-resolved optical systems to their zero-point energy has eluded laser cooling because of strong optical absorption heating. The alternative method of passive cooling suffers from the same problem, as the requisite milliKelvin environment is incompatible with the strong optical driving needed by many quantum protocols. Here, we employ a highly sideband-resolved silicon optomechanical crystal in a ^{3}He buffer-gas environment at ∼2 K to demonstrate laser sideband cooling to a mean thermal phonon occupancy of 0.09_{-0.01}^{+0.02} quantum (self-calibrated using motional sideband asymmetry), which is -7.4 dB of the oscillator's zero-point energy and corresponds to 92% ground state probability. Achieving such low occupancy by laser cooling opens the door to a wide range of quantum-optomechanical experiments in the optical domain.

Efficacy and safety of early initiation of sacubitril-valsartan therapy in patients with acute decompensated heart failure / 中华心血管病杂志

Objective: To assess the efficacy and safety of the initiation of sacubitril-valsartan （ARNI） therapy, as compared with ACEI therapy, after hemodynamic stabilization among patients hospitalized for acute decompensated heart failure （ADHF）. Methods: A total of 199 hospitalized patients for ADHF in our department from January 2017 to June 2019 were included in this retrospective analysis. According to the medication early after hemodynamic stabilization, patients were divided into ARNI group (n=92) and ACEI group (n=107). Among the included patients, 61 patients with newly diagnosed heart failure at the time of admission were also divided into ARNI group (n=30) and ACEI group (n=31) according to the applied medication. Clinical baseline data and follow-up results of enrolled patients were collected through the electronic medical records at admission, outpatient and telephone follow-up. The primary effectiveness observation index was left ventricular ejection fraction (LVEF) and left ventricular end diastolic dimension (LVEDD) measured by echocardiography; the secondary observation index was death from any causes and hospitalization for heart failure. Safety outcomes were the incidences of symptomatic hypotension, worsening renal function, hyperkalemia, and angioedema. Results: The clinical baseline characteristics were similar between ARNI group and ACEI group（all P>0.05）. The duration of follow up was (15.2±6.5) months in all patients enrolled, (12.3±5.0) months in ARNI group, and (18.2±6.5) months in ACEI group. At the end of follow-up, prevalence of an absolute LVEF increase of more than 5% was 48.9% (45/92) in ANRI group and 25.2% (27/107) in ACEI group (P=0.001). Percent of LVEF increase to more than 50% was 17.4% (16/92) in ANRI group and 3.7% (4/107) in ACEI group (P=0.001). Percent of patients with more than 10 mm LVEDD reduction was 14.1% (13/92) in ANRI group and 3.7% (4/107) in ACEI group (P=0.009). All-cause mortality rate was 5.7% (5/88) in ARNI group and 15.3% (13/85) in ACEI group (P=0.038). Rate of re-hospitalization due to heart failure was 50% (46/92) in ARNI group and 71% (76/107) in ACEI group（P=0.002）.The rates of symptomatic hypotension, worsening renal function, hyperkalemia, and angioedema were similar between ARNI group and ACEI group (all P>0.05). In patients with first diagnosed heart failure，percent of LVEF increase to more than 50% was 30% (9/30) in ANRI group and 6.5% (2/31) in ACEI group (P=0.017). Percent of more than 10 mm LVEDD reduction was 26.7%(8/30) in ANRI group and 3.2%(1/31) in ACEI group (P=0.012). Percent of an absolute LVEF increase of more than 5% was 53.3% (16/30) in ANRI group and 51.6% (16/31) in ACEI group (P=0.893). Re-hospitalization due to heart failure was 23.3% (7/30） in ARNI group and 73.3% (11/31) in ACEI group（P<0.01）. Rate of all-cause death tended to be lower in patients receiving ARNI (3.4% (1/29)) as compared to patients receiving ACEI (13.0% (3/23), P=0.197）. Conclusions: Among patients with heart failure with reduced ejection fraction hospitalized for ADHF, the initiation of ARNI therapy after hemodynamic stabilization is associated with a more significant improvement of cardiac remodeling and pump function than ACEI therapy and satisfactory safety. In ADHF patients with first diagnosed heart failure, initiation of ARNI therapy after hemodynamic stabilization can more effectively improve cardiac remodeling and pump function than treatment with ACEI.

Effects of hypothermia on the repolarization duration of ventricular myocytes in rats and its mechanism / 中国应用生理学杂志

To observe the effects of hypothermia on the repolarization duration and the expression of Kir2.1 protein of ventricular myocytes in isolated rat heart and explore the role of Kir2.1 protein. Eighteen healthy adult male Sprague-Dawley rats were randomly divided into three groups (n=6 per group): Control group (C group), 35℃ group (H group), 32℃ group (H group). Langendorff isolated heart models were established. After 15 min 37℃ K-H fluid banlanced perfusion, C group continued to perfuse the K-H solution at 37℃ for 30 minutes, H group continued to perfuse the K-H solution at 35℃ for 30 minutes, H group continued to perfuse the K-H solution at 32℃ for 30 minutes. At 15 min of balanced perfusion (T), and 30 min of continuous perfusion (T), the heart rate,and the MAP in the three layers of the left ventricular anterior wall were recorded, the action potential duration at 50% repolarization (MAPD), the action potential duration at 90% repolarization (MAPD) and transmural dispersion of repolarization(TDR) were calculated. At the same time, the occurrence of arrhythmia was recorded. The expression of Kir2.1 protein was measured by Western blot. The average optical density (AOD) and the distribution of Kir2.1 protein were measured by immunohistochemistry in the ventricular tissue measured by electrophysiology. Compared with T, the heart rate was decreased, MAPD and MAPD were prolonged significantly (P＜0.05), and TDR was increased significantly (P＜0.05) in H group, H group at T. Compared with C group, the HR was decreased, the MAPD was prolonged significantly (P＜0.05), TDR was increased significantly (P＜0.05),the expression and the AOD of Kir2.1 protein were decreased significantly (P＜0.05) in Hgroup, Hgroup at T. Compared with H group, the heart rate of H group was decreased significantly (P＜0.05), MAPD and MAPD were prolonged significantly (P＜0.05), and TDR was increased significantly (P＜0.05) at T. The distribution of Kir2.1 protein in group C was normal, while the distribution of Kir2.1 in H group and H group was disordered. Hypothermia prolonged the ventricular duration of repolarization and increased the dispersion of repolarization. The mechanism is related to the down-regulation the expression of Kir2.1 protein and the disorder of the distribution of Kir2.1 protein.
