To look for a novel micro traumatic and highly effective method to treat arterial and venous occlusive diseases, ultrasonic thrombus ablation technique was applied in 7 cases of arterio sclerosis obstruction (ASO) of the lower limbs and 15 cases of deep vein thrombosis (DVT) of the lower limbs. The indications, precautions during the operation, and postoperative treatment were summarized. Recanalization of the vessels was achieved in all the patients without perforation. Angiographic examination showed that the stricture of arteries of the patients with ASO was reduced from (93?12)% to (12?6)%, and their symptoms were remarkably ameliorated. In 15 DVT patient, venous occlusion was reduced from 100% to (8?2)% on angiogram, and edema of their limbs subsided. We consider ultrasonic thrombus ablation is an effective, safe, and minimally traumatic treatment modality for arterial and venous occlusive diseases.

Objective To evaluate the efficacy of parecoxib sodium for prevention of post-thoracotomy pain syndrome.Methods Ninety ASA physical status Ⅰ or Ⅱ patients,aged 40-64 yr,weighing 50-80 kg,scheduled for elective thoracotomy,were equally and randomly divided into 3 groups using a random number table:control group (group C) and two different treatments with parecoxib sodium groups (P1 and P2 groups).At 20 min before skin incison,parecoxib sodium 40 mg was injected intravenously in P1 and P2 groups,while the equal volume of normal saline was given in group C.An increment of parecoxib sodium 40 mg was given every 12 h for 6 times after surgery in group P2.General anesthesia combined with epidural anesthesia was used during surgery and patient-controlled epidural analgesia was used for postoperative analgesia in the three groups.Morphine was used as rescue analgesic to maintain VAS score ≤ 3.The consumption of morphine within 72 h after operation,development of adverse effects and development and duration of pain (VAS score ＞ 3) within 6 months after operation were recorded.The blood coagulation was measured at 72 h after operation.Results Morphine was not used within 72 h after operation in P2 group.The abnormality of blood coagulation at 72 h after operation was not observed in the three groups.Compared with group C,no significant changes were found in the incidence and duration of pain within 6 months after operation in P1 group (P ＞ 0.05),the incidence of pain was significantly decreased and duration of pain was shortened within 6 months after operation in P2 group,and the incidence of nausea,vomiting and pruritus was decreased in P1 and P2 groups (P ＜ 0.05 or 0.01).The incidence of nausea,vomiting and pruritus was significantly lower in P2 group than in P1 group (P ＜ 0.01).Conclusion Continuous application of parecoxib sodium for 72 h can decrease the development of post-thoracotomy pain syndrome without increasing the incidence of adverse effects.

Objective:To summarize and compare the characteristics of oral microbiota in women during the preconception period and the third trimester.Methods:This retrospective cohort study involved 55 women who were recruited in the Preconceptional Offspring Trajectory Study (PLOTS) conducted by Fudan University and followed up to the third trimester in the Maternal and Child Health Care Hospital of Jiading District of Shanghai from September 2016 to December 2019. A total of 110 unstimulated saliva samples were collected in the preconception period ( n=55) and the third trimester ( n=55). Features of oral microbiota in the samples were analyzed by 16S rRNA gene-based sequencing. Moreover, the related factors were also analyzed. Paired t test or Wilcoxon matched-pairs signed-ranks test were used to analyze the differences in α-diversity during preconception and the third trimester; t test, analysis of variance (ANOVA), Kruskal-Wallis test and Mann-Whitney U test for comparison between groups with different characteristics and permutational multivariate analysis of variance (PerMANOVA) for β-diversity were used; Linear discriminant analysis (LDA) effect size (LEfSe 1.0) was used to identify the iconic oral flora. Results:(1) The Ace index of oral microbiota was significantly lower in the third trimester than that in the preconception period [661.14(578.15-752.85) vs 730.64 (632.40-911.00), T=1 077.00, P=0.010]. There was also a significance difference in β-diversity ( F=12.539, R2=0.104, P=0.001). Some species such as Saccharibacteria_TM7_G3, Prevotella_7, Absconditabacteria_SR1_G1, Porphyromonas, Ruminococcaceae_UCG_014, Prevotella, Peptostreptococcus, Prevotella_2, Alloprevotella, Parvimonas, Solobacterium and Eubacterium_nodatum_group in saliva were statistically more abundant in the third trimester than those in the preconception period (all P<0.05). (2) The third-trimester Shannon index was lower among those with lower income [5.44 (5.08-5.77) vs 5.75 (5.44-6.12), U=219.00, P=0.029] and those with gargle habit after meal or dessert [5.36 (4.91-5.48) vs 5.72 (5.44-6.05), U=374.00, P=0.046]. Conclusions:The features of oral microbiota vary in women during the preconception period and the third trimester. There is a significant increase in the abundance of oral pathogenic and opportunistic bacteria in the third trimester.

Zuotai (gTso thal) is a typical representative of Tibetan medicines containing heavy metals, but there is still lack of modem safety evaluation data so far. In this study, acute toxicity test, sub-acute toxicity test, one-time administration mercury distribution experiment, long-term mercury accumulative toxicity experiment and preliminary study on clinical safety of Compound Dangzuo were conducted in the hope of obtain the medicinal safety data of Zuotai. In the acute toxicity test, half of KM mice given the lethal dose of Zuotai were not died or poisoned, and LD50 was not found. The maximum tolerated dose of Zuotai was 80 g x kg(-1). In the subacute toxicity test, Zuotai could reduce ALT, AST, Crea levels in serums under low dose (13.34 mg x kg(-1) x d(-1)) and medium dose (53.36 mg x kg(-1) x d(-1)), with significant difference under low dose, and increase the levels of ALT, AST, MDA, Crea in serums under high dose (2 000 mg x kg(-1) x d(-1)); besides, the levels of BUN and GSH in serums reduced with the increase in dose of Zuotai, indicating a significant dose-effect relationship. In the one-time administration distribution experiment, the content of mercury in rat kidney, liver and lung increased after the one-time administration with Zuotai, with a significant dose-dependent relationship in kidney. In the long-term mercury accumulative toxicity experiment, KM mice were administered with equivalent doses of Zuotai for 4.5 months and then stopped drug administration for 1.5 months. Since the 2.5th month, they showed significant mercury accumulation in kidney, which gradually reduced after drug withdrawal, without significant change in mercury content in liver, spleen and brain and ALT, AST, TBIL, BUN and Crea in serum. At the 4.5th month after drug administration, KM mice showed slight structural changes in kidney, liver and spleen tissues, and gradually recovered to normal after drug withdrawal. Besides, no significant difference in weight gain was found between the Zuotai group and the control group. According to the findings of the clinical safety study of Dangzuo, after subjects administered Dangzuo under clinical dose for one month, their serum biochemical indicators, blood routine indicators and urine routine indicators showed no significant adverse change. This study proved that traditional Tibetan medicine Zuotai was slightly toxic, with a better safety in clinical combined administration and no adverse effects on bodies under the clinical dose and clinical medication cycle. However, long-term high-dose administration of Zuotai may have a certain effect on kidney.

The mammalian target of rapamycin (mTOR), a serine/threonine protein kinase, acts as a "master switch" for cellular anabolic and catabolic processes, regulating the rate of cell growth and proliferation. Dysregulation of the mTOR signaling pathway occurs frequently in a variety of human tumors, and thus, mTOR has emerged as an important target for the design of anticancer agents. mTOR is found in two distinct multiprotein complexes within cells, mTORC1 and mTORC2. These two complexes consist of unique mTOR-interacting proteins and are regulated by different mechanisms. Enormous advances have been made in the development of drugs known as mTOR inhibitors. Rapamycin, the first defined inhibitor of mTOR, showed effectiveness as an anticancer agent in various preclinical models. Rapamycin analogues (rapalogs) with better pharmacologic properties have been developed. However, the clinical success of rapalogs has been limited to a few types of cancer. The discovery that mTORC2 directly phosphorylates Akt, an important survival kinase, adds new insight into the role of mTORC2 in cancer. This novel finding prompted efforts to develop the second generation of mTOR inhibitors that are able to target both mTORC1 and mTORC2. Here, we review the recent advances in the mTOR field and focus specifically on the current development of the second generation of mTOR inhibitors as anticancer agents.
