ABSTRACT
ObjectiveTo explore the anti-tumor effect and mechanism of Shenqi Yiliu prescription in the intervention of pyroptosis. MethodTen male BALB/c mice were randomly selected and assigned to the blank group. The remaining 40 mice underwent the induction of the liver cancer xenograft model. After 5 days of modeling， 40 surviving mice were randomly divided into model group， cisplatin group ［2.5×10-3 g·kg-1·（3 d）-1］， Shenqi Yiliu prescription group （27 g·kg-1·d-1）， and a combination group （Shenqi Yiliu prescription group + cisplatin）. The mice in the blank group and the model group were treated with an equal volume of normal saline for 10 days. The general conditions of mice in each group were observed. After the intervention， the tumor weight of the mice was weighed and the tumor inhibition rate was calculated. Hematoxylin-eosin （HE） staining was used to observe the pathological changes in tumor tissues. The levels of mouse liver function indicators， including alanine aminotransferase （ALT） and aspartate aminotransferase （AST） were detected. The TdT-mediated dUTP-biotin nick end labeling （TUNEL） assay was used to detect DNA damage in mouse tumor tissue cells. Immunohistochemistry （IHC）， immunofluorescence （IF）， and Western blot were used to detect the protein expression levels of NOD-like receptor protein 3 （NLRP3）， cysteinyl aspartate-specific protease-1 （Caspase-1）， and gasdermin D （GSDMD） in tumor tissues. The levels of interleukin-1β （IL-1β） and interleukin-18 （IL-18） in tumor tissues were detected by enzyme-linked immunosorbent assay （ELISA）. ResultCompared with the mice in the blank group， those in the model group were in a poor mental state， sleepy， and lazy， and their fur color was dull， with increased levels of serum ALT and AST in liver function tests （P<0.01）. Compared with the model group， the groups with drug intervention showed improved mental state， inhibited tumor growth to varying degrees， and decreased tumor weight， and the tumor inhibition rate in the combination group was the highest （P<0.01）. HE staining showed that the pathological and morphological lesions of the tumor tissues in the model group were significant， while those in all groups with drug intervention were improved to a certain extent. The karyolysis and nuclear rupture in the Shenqi Yiliu prescription group and the combination group were more significant. In the liver function test， the serum ALT and AST levels of mice in the Shenqi Yiliu prescription group and the combination group decreased （P<0.01）， and the inflammatory factors IL-1β and IL-18 in each group with drug intervention decreased （P<0.05， P<0.01）. Among them， the declining trend of IL-1β and IL-18 in the Shenqi Yiliu prescription group was the most significant （P<0.01）. TUNEL staining showed that the positive TUNEL staining in each group with drug intervention decreased after intervention （P<0.05， P<0.01）， especially the cisplatin group and Shenqi Yiliu prescription group （P<0.01）. Western blot， IHC， and IF found that the protein expression levels of NLRP3， Caspase-1， and GSDMD in each group with drug intervention decreased （P<0.05， P<0.01）. Compared with the mice in the cisplatin group， those in the Shenqi Yiliu prescription group and the combination group had better mental state and regular tumor morphology， and the tumor weight of the mice in the combination group decreased （P<0.05）. The levels of ALT and AST in the Shenqi Yiliu prescription group decreased （P<0.05）， and the levels of IL-1β and IL-18 in the Shenqi Yiliu prescription group and the combination group decreased （P<0.05， P<0.01）， especially in the combination group （P<0.01）. The results of IHC showed that the expression of GSDMD protein in the tumor tissues of mice in the combination group was reduced （P<0.01）. IF detection showed that the expression of NLRP3 in the tumor tissues of the Shenqi Yiliu prescription group was reduced （P<0.01）. The results of Western blot showed that the expression level of NLRP3 protein in the Shenqi Yiliu prescription group and the combination group decreased （P<0.01）， and the expression level of Caspase-1 protein in the combination group decreased （P<0.01）. The decrease in GSDMD protein expression was not significant， and the difference was not statistically significant. ConclusionShenqi Yiliu prescription combined with cisplatin has an obvious anti-tumor effect， which may be achieved by down-regulating the NLRP3/Caspase-1/GSDMD inflammatory pyroptosis pathway to inhibit cell pyroptosis， and relieve the inflammatory response in mice with liver cancer.
ABSTRACT
Objective:To evaluate the effect of individualized blood pressure management on postoperative delirium in elderly hypertensive patients undergoing radical resection for gastrointestinal tumor.Methods:One hundred and sixty elderly hypertensive patients of both sexes, aged 60-80 yr, with body mass index of 19-28 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, scheduled for elective radical resection for gastrointestinal tumor under general anesthesia, were divided into 2 groups ( n=80 each) using a random number table method: standardized blood pressure management group (group S) and individualized blood pressure management group (group I). Combined intravenous-inhalational anesthesia was performed, and BIS values were maintained at 40-60 and heart rate at 50-100 times/min during surgery in both groups. In group S, intraoperative systolic blood pressure was maintained above 90 mmHg with a decrease of less than 30% of the baseline value, while intraoperative fluctuation of systolic blood pressure was maintained less than 10% of the baseline value in group I. The use of vasoactive agents, numerical rating scale scores within 3 days after operation, and length of hospital stay were recorded. Postoperative delirium was evaluated by Confusion Assessment Method within 5 days after surgery. Results:Compared with group S, the intraoperative usage rate of norepinephrine was significantly increased, the incidence of postoperative delirium was reduced( P<0.05), and no significant change was found in the numerical rating scale scores and length of hospital stay in group I ( P>0.05). Conclusions:Individualized blood pressure management can reduce the development of postoperative delirium in elderly hypertensive patients undergoing radical resection for gastrointestinal tumor.
ABSTRACT
Circadian rhythm is a phenomenon of diurnal changes in life activities formed by a transcription-translation feedback loop of biological clock genes affected by external environmental conditions. The circadian rhythm system controls almost all physiological processes in the organism, and these processes will change as the external environment changes. Previous studies have shown that the hypothalamic-pituitary-thyroid axis in mammals is regulated by the central diurnal pacemaker of the suprachiasmatic nucleus of the hypothalamus, so part of the thyroid function is controlled by the biological clock, and the secretion of thyroid hormones in blood can present a circadian rhythm. However, the molecular mechanism of the biological clock's regulatory effect on thyroid is still unclear. Whether circadian rhythm interference is related to the disorder of thyroid function or the occurrence of thyroid diseases is worthy of attention. This paper focused on the research progress of biological clock, circadian rhythm, and thyroid function, specifically the characteristics of circadian rhythm of thyroid physiological function and the effects of sleep deprivation, light at night, and night shift work on thyroid function, elaborated the relationships of circadian rhythm disorder with thyroid function and thyroid diseases represented by thyroid malignant tumors. The review summarized that circadian rhythm disorder may disrupt the rhythmic secretion of thyroid hormones, but no clear conclusion is reached yet on any effect on thyroid diseases, especially thyroid malignant tumors, so it is necessary to further strengthen the relevant epidemiological and molecular mechanism research.
ABSTRACT
HBeAg seroconversion is an important process during antiviral therapy for patients with HBeAg-positive chronic hepatitis B (CHB), while the first-line antiviral drugs, such as entecavir and tenofovir disoproxil fumarate, tend to have low HBeAg clearance rate and/or seroconversion rate, and at present, there is still a lack of effective radical treatment regimens. Latest studies have shown that fecal microbial transplantation (FMT) can induce HBeAg clearance in HBeAg-positive CHB patients receiving long-term antiviral therapy. This article reviews the research advances in the role of FMT in inducing HBeAg clearance in HBeAg-positive CHB patients and points out that FMT may become a new treatment regimen for HBeAg-positive CHB patients.

ABSTRACT
Objective To investigate the diagnosis and treatment status of neonatal respiratory dis-tress syndrome (NRDS) in Inner Mongolia and explore the problems and countermeasures for NRDS diagno-sis and treatment. Methods Data of infants with NRDS in 4 hospitals(3 hospitals were in the west,which were the Affiliated Hospital of Inner Mongolia Medical University,Baotou Steel Three Hospital and Ordos Central Hospital,1 hospital was in the east,which was the Affiliated Hospital of Chifeng Institute) participat-ing in the study during the period from 1th January,2016 to 30th June,2018 were investigated retrospectively with descriptive epidemiological survey,including basic situation,perinatal period, clinical manifestations, treatment,complications and prognosis. Results Among 11406 newborns admitted in 4 hospitals during the study period,748 infants were diagnosed with NRDS,accounting for 6. 56％ . In the eastern region,279 infants were diagnosed with NRDS,the rate was 9. 30％ ,and in the western region were 469(5. 58％ ). The average hospitalization time in the eastern region was longer than that in the western region,and the age of motherswas higher than that in the western region. There were significant differences between the two groups(P <0. 05). The antenatal hormone use,cesarean delivery,multiple gestation,low Apgar score,premature rupture of membrane in the western region were higher than those in the eastern region(P < 0. 05). The proportion of NRDS grade Ⅰ and gradeⅢ,pulmonary surfactant(PS) utilization ratio and INSURE technology usage in the eastern region were higher than those in the western region. The ratio of NRDS(grade Ⅱ) and the first dose of PS in the western region were higher than those in the eastern region(P < 0. 05). The total mortality of neonates with NRDS was 6. 15％ (46 / 748). The incidence rates of patent ductus arteriosus,bronchopulmo-nary dysplasia,necrotizing enterocolitis,ventilator-associated pneumonia in the western region were higher than those in the eastern region(P < 0. 05). Conclusion The level of diagnosis and treatment of NRDS in four hospitals in two districts of Inner Mongolia varies widely. But overall compared with other areas,the treatment of NRDS in Inner Mongolia has the problems of low antenatal hormone use,insufficient use of PS and INSURE technology,and late use of PS. The treatment of NRDS should continue to standardize antenatal hormone use,early and sufficient use of PS,the promotion of the use of INSURE technology.

ABSTRACT
Currently,surgical treatments in tennis elbow include open,arthroscopic and percutaneous procedures.Open surgery,having definite curative effects,is commonly used.There are different surgical methods based on different hypotheses about the pathogenesis of tennis elbow,such as detachment of common extensor origin,resection of annular ligament,denervation surgery and resection of microvascular nerve bundle.There is a huge difference in open surgery of tennis elbow between China and abroad.Debriding or releasing extensor carpi radialis brevis and common extensor tendon are mostly used abroad though it remains controversial whether we should release or debride with tendon,as well as whether it is better to decorticate on lateral epicondyle or not.In China,tennis elbow is treated with resection of microvascular nerve bundle except for debridement and release of tendon.As for evaluation criteria,the following methods,grip strength,grading system and visual analogue scale have been used in researches.However,cure rate and response rate are valuation criteria for resection of microvascular nerve bundle in China.The evaluation criteria are different among various surgical methods,even in the methods,especially for grading system.Each research has unique standards to define excellent,good,fair and poor outcomes.Complications of tennis elbow open surgery are rare,while subcutaneous hematoma is the common complication.

<p><b>OBJECTIVE</b>To study the protective effect of oxymatrine (OMT) on myocardial fibrosis induced by acute myocardial infarction in rats and its effect on TGF-beta-Smads signal pathway.</p><p><b>METHOD</b>Arteria coronaria ligation-induced acute myocardial infarction model was established in rats. The survived rats were randomly allotted into the model group, 50, 25, 12.5 mg x kg(-1) OMT groups, the 50 mg x kg(-1) captopril group, and the Sham-operated group which was treated as the model group without the arteria coranaria ligation. After 8 weeks of ligation, myocardial fibrosis was detected by HE and Masson staining, and the RT-PCR method were used to detect the expression of mRNA of TGF-beta-Smads signal system.</p><p><b>RESULT</b>The histopathological examination showed decrease in cardiocytes, deposition of extra-cellular matrix, and increase of collagen contents after 8 weeks of ligation. RT-PCR results showed that mRNA expressions of TGF-beta1, TbetaR1, Smad2, Smad3 and Smad4 significantly increased, but mRNA expression of Smad7 is remarkable lower than the sham-operated group. Treatment with OMT for 8 weeks could remarkably inhibit myocardial fibrosis, decrease mRNA expressions of TGF-beta1, TbetaR1, Smad2, Smad3, and Smad4, and increase mRNA expressions of Smad7.</p><p><b>CONCLUSION</b>OMT has the inhibitory effect on the experimental myocardial fibrosis induced by AMI in rats. Its mechanism may be closely related to TGF-beta-Smads signal system.</p>
