Aim To study the inhibitory and apoptosis-inducing effects of aspisol on proliferation of B16 melanoma in vitro and in vivo. Methods The effect of aspisol on the proliferation of B16 cells was analyzed by MTT assay; its effect on cell apoptosis was measured by flow cytometry. The suspension of melanoma cells was injected subcutaneously into forelimb axillas of C57BL/6J mice to establish xenograft models. From the next day, the mice received intraperitoneal injection of aspisol in different concentrations once a day for 28 days; the mice received injection of dacarbazine (DTIC) were used as positive controls,and received injection of normal saline (NS) were used as negative controls. The inhibition rate of tumor growth was calculated .The apoptosis rate was detected by TUNEL assay. The expression of Survivin and C-erbB-2 was detected by immunohistochemistry. Results Aspisol inhibited the proliferation of B16 cells, with the inhibition rate up to (68.78?1.27)%, and induced the apoptosis with the highest apoptosis rate up to 15.8%.The inhibition rate of tumor growth was 15.0% in 200 mg?kg-1 aspisol group, 32.3% in 400 mg?kg-1 aspisol group, 49.4% in 800 mg?kg-1 aspisol group,and 51.4% in 40 mg?kg-1 DTIC group. Typical apoptotic morphologic changes were seen in the 4 groups. Survivin and C-erbB-2 expression was significantly lower in aspisol groups than in NS group. Conclusion Aspisol could inhibit proliferation and induce apoptosis of B16 melanoma cells in vitro and in vivo, which may be correlated to down-regulation of Survivin and C-erbB-2.

Background and purpose:Many studies indicate that nonsteroidal anti-inflammatory drugs(NSAIDs) may inhibit cancer growth.However,the molecular mechanisms may involve different pathway and still remain unclear.The aim of this experiment was to investigate the influence of aspisol against breast cancer lines,including MDA-MB-231(estrogen receptor-negative),MCF-7(estrogen receptor-positive),and reveal the potential signaling pathway mechanism of aspisol effect on breast cancer lines.Methods:MDA-MB-231 and MCF-7 human breast cancer cell lines were treated with aspisol in vitro.Cell proliferation was evaluated by MTT assay and rate of apoptosis were determined by flow cytometry.Extracellular signal regulated kinase(ERK),phosphor-ERK(P-ERK) protein expressed in breast cancer cell lines were analyzed by Western blot.Results:①The results of MTT assay demonstrated that the growth of MDA-MB-231,MCF-7 cells were inhibited by aspisol in a time-and dose-dependent fashion(P0.05).Conclusions:aspisol inhibits proliferation and induces apoptosis not only in ER-positive but also in ER-negative breast cancer cells.The mechanism may relate to ERK signal pathway.

Objective:To compare the analgesic effects of naborphine and desorine after surgery for supracondylar fracture of humerus in children.Methods:Eighty-seven children with supracondylar fracture of humerus who received surgical treatment in Zhoushan Hospital of Traditional Chinese Medicine between January 2019 and January 2020 were included in this study. They were randomly assigned to receive postoperative analgesia either with dezocine (control group, n = 44) or naborphine (observation group, n = 43). The postoperative agitation score, postanesthetic recovery score, postoperative visual analogue scale score, and adverse reactions were determined between the two groups. Results:The heart rate and mean arterial pressure at the time of extubation were (102 ± 7) beats/min and (83 ± 6) mmHg respectively in the observation group, which were significantly lower than those in the control group [(115 ± 8) beats/min, (92 ± 7) mmHg, t = 6.214, 8.283, P < 0.05]. In the observation group, the postoperative agitation score was (4.45 ± 0.34) points, (5.02 ± 0.38) points, and (3.65 ± 0.39) points, at the time of spontaneous eye opening, at the time of extubation and at 30 minutes after extubation respectively, which were significantly lower than those in the control group [(5.31 ± 0.48) points, (5.75 ± 0.35) points, (4.12 ± 0.37) points, t = 6.392, 7.194, 7.382, all P < 0.05]. At 30 min, 3 h and 6 h after surgery, the visual analogue scale scores in the observation group were significantly lower than those in the control group ( t = 5.345, 6.124, 7.553, P < 0.05). The time to return to spontaneous breathing, the time to spontaneous eye opening and the time to extubation in the observation group were (7.32 ± 4.17) min, (11.65 ± 3.32) min, (12.13 ± 2.41) min, respectively, which were significantly shorter than those in the control group [(10.34 ± 4.15) min, (14.43 ± 3.18) min, (15.16 ± 2.23) min, t = 7.216, 5.382, 7.319, all P < 0.05]. The incidence of adverse reactions in the observation group was significantly lower than that in the control group [6.97% (3/43) vs. 27.27% (12/44), χ2 = 6.280, P < 0.05]. Conclusion:Naborphine for analgesia after surgery for supracondylar fracture of humerus in children can effectively reduce the incidence of agitation during the recovery period, enhance postoperative analgesic effect, and lower the incidence of reverse reactions.

Type B aortic dissection is a life-threatening aortic disease.With the development of clinical classification and diagnostic method,the mortality of type B aortic dissection has been greatly decreased.In respect of treatment,endovascular repair due to minimally invasive advantages become the first choice for the treatment of complicated type B aortic dissection.For non-complicated type B aortic dissection,endovascular repair also gradually replace drug treatment,and showed good efficacy.Open surgery is only available for patients who ate not suitable for endovascular repair or repair failure or patients with connective tissue disease.

The development and application of processing technology is closely related to the quality of Chinese medicine. Currently, Chinese medicine processing is still in the mechanization stage with limited processing equipment, low levels of automation and intelligence. As a result, the imprecise control of parameters during processing leads to unstable quality of Chinese herbal pieces. However, with the arrival of the big data era and the continuous development of "Internet+", Chinese medicine processing technology and equipment have been continuously improved and updated, and gradually shifted to the development direction of automation and intelligence. The linkage production technology of Chinese herbal pieces optimizes the separate processing equipment coupling into the production line for continuous manufacture of Chinese herbal pieces, intending to improve production efficiency. The large-scale industrialized production of Chinese herbal pieces tends towards digital technology of processing experience and online inspection technology based on machine vision, electronic nose, and electronic tongue. These technologies are crucial prerequisites for standardizing the parameters of Chinese medicine processing. And further by docking the processing process and equipment with the internet, realizing the intelligent control of the production process is an important process for the transformation and upgrading of Chinese herbal piece industry in the future. In this paper, we summarized the development characteristics of different stages of Chinese medicine processing technology, combed application and development of processing theory, the evolution of processing equipment, and problems in the current industrial development stage of Chinese medicine processing, in order to provide ideas and methods for achieving digital and intelligent innovation of processing technology as well as high-efficient and high-quality production of Chinese herbal pieces.

Objective:
To evaluate the short-term efficacy of branched TEVAR in the treatment of complex aortic arch lesions.
Methods:
The clinical data of 18 patients with aortic lesions requiring reconstruction of the left subclavian artery who were treated with branch TEVAR technology in Tianjin Medical University General Hospital from Apr 2016 to Dec 2018 were analyzed retrospectively.
Results:
There were 16 cases using Castor external branch stent implantation and 2 cases of self-made internal branch stent. The success rate of device release was 100%, the success rate of operation was 100%, and there were no intraoperative deaths. Postoperative complications occurred in 2 cases: one proximal stent tear dissection required open surgery, one died of massive myocardial infarction.Seventeen patients were followed up for 1-8 months. CTA examination in 16 patients 30 days after surgery, found 1 patient with type Ⅲ endoleak. CTA examination done in 8 patients 6 months after surgery found distal occlusion of left subclavian artery stent in 1 patient necess itating distal stent implantation.
Conclusion
The branch TEVAR technique is effective method to reconstruct the arch branched artery.
