(P<0.05)ConclusionCognitive therapy and acupuncture used together shows more efficacy on insomnia compared with acupuncture alone.

OBJECTIVETo study the effect of catalpol and puerarin freeze-dried powder for injection (CPFPI), a new compound traditional Chinese medicine (TCM) preparation, on coagulability, hemorheology and NO in rats with qi-deficiency and blood-stasis syndrome.

METHODThe model of rats with qi-deficiency and blood-stasis syndrome was established by hunger, fatigue, cold-dampness, panic and high fat diet. Coagulation time (CT) was observed by the glass method, and bleeding time (BT) was measured by tail-cutting method. The effects of CPFPI were also evaluated with prothrombin time (PT), activated partial thromboplastin time (APTT) and thrombin time (TT). HCT was measured by the electric tesistance method, hemorheology indicators were observed by auto-hemorheological instrument. The level of NO in blood serum was measured by NO assay kit.

RESULTCPFPI 65.40 mg x kg(-1) significantly prolonged CT, BT, PT, APTT and TT in rats. The viscosity of whole blood and plasma, hematocrit, erythrocyte aggregation and rigidity index, and reduced viscosity of whole blood in 65.40 mg x kg(-1) groups were lower than model group. CPFPI 65.40 mg x kg(-1) can raise the level of NO in blood serum. 32.70 mg x kg(-1) markedly prolonged CT, PT and APTT and decreased whole blood viscosity, erythrocyte aggregation index and whole blood reduction viscosity.

CONCLUSIONCPFPI has a significant effect in improving coagulability and hemorheology index and enhancing NO content in blood serum.

Objective To observe the protective effect of Kudiezi Injection (KI) on vascular endothelial cells, and study initially the effective mechanism of PKCδ/MARCKS signal pathway after hypoxia injury.Methods The hypoxia injury model was induced by CoCl2 in human umbilical vein endothelial cells (HUVEC), and then divided into normal group, model group, KI group and Rottlerin group.The cytomorphologic changes were observed by using light microscope 24 h after hypoxia injury, vitality of HUVEC was detected by using methyl thiazolyl tetrazolium test (MTT), and distributions and expressions of p-PKCδ and p-MARCKS were detected by using immunocytochemical method and Western Blot in all groups.Results KI and Rottlerin alleviated significantly the cytomorphologic changes, and enhanced significantly the vitality of cells after hypoxia injury (P<0.01).The expressions of p-PKCδ and p-MARCKS were significantly increased in model group compared with normal group (P<0.05), and were significantly inhibited by KI and Rottlerin (P<0.05).Conclusion KI has a protective effect on vascular endothelial cells after hypoxia injury, and the mechanism is related to down-regulation of vitality of PKCδ/MARCKS signal pathway.

Hyperlipidemia plays a vital role in cardiovascular disease, and threatens our lives. The aim of this paper is to study the effects of Shuanghua granules on blood lipid in normal mice and different hyperlipidemia models. Acute and endogenous hyperlipidemia was induced in mice with yolk and Triton WR-1339 respectively. The model of hyperlipidemia in rats was set up by feeding high cholesterol diet. Then preventive effects of Shuanghua granules was observed compared with lovastatin and Zhibituo. We found that Shuanghua granules 5.6, 11.3, 22.5 g x kg (-1) could significantly reduce the serum TG level in normal mice (P < 0.01, P < 0.05). No significant difference was found in liver index, serum TG and HDL-C levels. When the mice were treated with either yolk or Triton WR-1339 in the presence of Shuanghua granules, the plasma lipoprotein levels (TC and LDL-C) were significantly reduced (P < 0.01, P < 0.05). Shuanghua granules could reduce the serum TC, TG, LDL-C, MDA, NEFA and liver TC, TG, LDL-C levels, simultaneously raise serum and liver HDL-C, serum SOD, LPL, HL, LA levels of hyperlipidemia rats (P < 0.01, P < 0.05). Shuanghua granules also significantly reduced whole blood viscosity, RV, etaP, IER and IEA (P < 0.01, P < 0.05), and lowered fatty degeneration of liver tissue. Compared with hyperlipidemia model, there was no significant increase in faeces lipoids concentrations. The results confirmed the mechanism of blood lipid regulating effects of Shuanghua granules is probably related with its antioxidation, regulating hemorheology and improving LPA, HL, LA enzymatic activity.

Closed-loop hospital management can effectivly cope with the COVID-19 pandemic. In order to ensure the continuity of treatments for hemodialysis patients under closed-loop management and minimize possible medical and infection risks, Huashan Hospital affiliated to Fudan University and 9 hospitals in Shanghai established a hemodialysis alliance in January 2021.The alliance optimized hemodialysis resources within the region through overall planning by preparing sites, materials and personnel shifts in advance, and establishing management systems and work processes to ensure that patients could be quickly and orderly diverted to other blood dialysis centers for uninterrupted high-quality hemodialysis services, in case that some hemodialysis centers in the alliance under closed-loop management.From November 2021 to April 2022, 317 of 1 459 hemodialysis patients in the alliance were diverted to other centers for treatment, accumulating 1 215 times/cases of treatments without obvious adverse reactions. The practice could provide a reference for medical institutions to quickly establish mutual support mode under major public health events.

OBJECTIVE To investigate the effect and mechanism of gracillin from Reineckia carnea on autophagy in non- small cell lung cancer A549 cells. METHODS Using A549 cells as subjects， the effects of different concentrations of gracillin （0.25， 0.5， 1， 2， 4 μmol/L） on the proliferation of cells were detected by CCK-8 after being treated for different time （12， 24， 48 h）. Compared with the control group without medication， the effect of gracillin （2 μmol/L） on the formation of autophagosomes in cells was observed by transmission electron microscope after 24 h of exposure. The aggregation of GFP-LC3 on autophagosome membrane was detected by GFP-LC3 plasmid transfection after being treated with gracillin （0.25， 0.5， 1， 2 μmol/L） for 24 h. Quantitative real-time PCR and Western blot assay were used to detect the mRNA and protein expressions of family with sequence similarity 102 member A（FAM102A）， the expressions of autophagy-related proteins [p62， Beclin-1， microtubule-associated protein 1 light chain 3B （LC3B）]， and the expressions of phosphoinositide 3-kinase （PI3K）/protein kinase B （Akt） signaling pathway-related proteins in A549 cells after being treated with gracillin （0.25， 0.5， 1 and 2 μmol/L） for 24 h. RESULTS Gracillin significantly inhibited the proliferation of A549 cells in a concentration- and time-dependent manner. The IC50 was 2.55 μmol/L at 24 h. After 24 h of gracillin treatment， autophagosomes with bilayer membrane structure were found in the cell cytoplasm， and GFP-LC3 green fluorescent spots on autophagosome membrane were obvious， representing an increasing trend as drug concentration. Compared with the control group， mRNA and protein expressions of FAM102A （0.5， 1， 2 μmol/L groups）， protein expression of Beclin-1 （1， 2 μmol/L groups） and LC3B-Ⅱ/LC3B-Ⅰ ratio （2 μmol/L group） were significantly increased in different concentrations of gracillin groups， while the protein expression of p62 （1， 2 μmol/L groups）， and the protein phosphorylations of Akt （1， 2 μmol/L groups） and PI3K （2 μmol/L group） were all decreased significantly （P＜0.05 or P＜0.01）. CONCLUSIONS Gracillin can promote excessive autophagy in A549 cells by up-regulating mRNA and protein expressions of FAM102A and inhibiting PI3K/Akt signaling pathway， thus inhibiting cell proliferation.
