ABSTRACT

Objective To investigate the serum levels of thyroid function and hs-CRP expression in patients with syphilis and their relationship with coagulation function. Methods A total of 80 syphilis patients admitted to Bazhong Central Hospital from January 2020 to January 2022 were selected as the study subjects and set as the observation group. In addition, 80 healthy individuals were selected as the control group, and 80 psoriasis patients were selected as the disease control group. Thyroid function, hs-CRP and coagulation function among different groups were compared. The correlation between thyroid function, hs-CRP, and coagulation function in patients with syphilis was analyzed, and the effectiveness of these parameters in predicting syphilis was analyzed. Results The values of FT3, FT4, TSH and hs-CRP in the observation group were higher than those in the control group and the disease control group (P<0.05). The abnormal rates of thyroid function and hs-CRP level in the observation group were higher than those in the control group and the disease control group (P<0.05). PT, APTT, and TT of the observation group were higher than those of the control group and the disease control group (P<0.05). The abnormal rate of coagulation function in the observation group was higher than that in the control group and the disease control group (P<0.05). The levels of FT3, FT4, TSH, hs-CRP, PT, APTT, and TT in the first stage were lower than those in the second and third stages, while these parameters in the secondary stage were lower than those in the third stage (P<0.05). The severity of syphilis was positively correlated with FT3, FT4, hs-CRP, APTT, and TT (P<0.05). Among these indicators, TT was more effective in the diagnosis of syphilis. Conclusion Syphilis patients have hyperthyroidism, accompanied by coagulation dysfunction and abnormal increase in hs-CRP, which are all related to the condition of syphilis patients. The combined prediction of syphilis patients has high effectiveness.

ABSTRACT

Objective@#To explore the relative risks of rotavirus diarrhea after exposure to different levels of atmospheric pressure in children in Guangzhou City, so as to provide reference for improving public awareness of high atmospheric pressure exposure.@*Methods@#The study used the China Notifiable Communicable Diseases Network System and China Meteorological Science Data Sharing Service Network to collect meteorological data and data relating to daily cases of rotavirus diarrhea in children at Guangzhou Women and Children s Medical Center from 2012 to 2020. The association between rotavirus diarrhea and atmospheric pressure was analyzed using distributed lag non linear models (DLNM). The relative risks of different sex and age sub groups exposed to different atmospheric pressures were also evaluated.@*Results@#A total of 18 587 cases of rotavirus diarrhea were reported from 2012 to 2020, among which 11 662 cases (62.7%) were boys, and 12 582 cases (67.7%) were children aged 6 to 24 months old, which represented the highest proportion. The results of the DLNM showed that the relative risk of rotavirus diarrhea was the highest on the day of exposure to extreme high atmospheric pressure ( RR =1.50, 95% CI =1.24-1.82, P <0.05) and the effect could last for 28 days. Risk of rotavirus diarrhea was low for exposure to low pressure within 2 weeks ( P <0.05). During extremely high atmospheric pressure weather, RR was higher in girls ( RR =3.31, 95% CI =1.46-7.49, P <0.05) than that in boys ( RR =1.98, 95% CI =0.96-4.07, P >0.05). Among different age sub groups, RR was the highest in children aged 24 to 60 months after exposure to the highest level of atmospheric pressure exposure ( RR =3.36, 95% CI =1.27-8.89, P <0.05).@*Conclusion@#In Guangzhou, exposure to high pressure increases the risk of rotavirus diarrhea in children. In the future, public awareness should be raised regarding the risk after exposure to high atmospheric pressure.

ABSTRACT

ObjectiveTo observe the clinical effect of Xijiao Dihuangtang combined with acupuncture on the treatment of systemic lupus erythematosus (SLE) with syndrome of intense heat toxin. MethodA total of 102 cases of SLE with syndrome of intense heat toxin (admitted from January 2020 to December 2021) were divided into a control group and an observation group by random number table method, with 51 cases in each group. Patients in the control group received conventional western medicine treatment (hydroxychloroquine sulfate + poonisone acetate tablets). Patients in the observation group were given Xijiao Dihuangtang combined with acupuncture based on the treatment of the control group. Clinical efficacy, onset time, symptom improvement time, skin lesion regression time, and hospital stays were recorded. Blood routine index change, 24 h urine protein levels, double-stranded DNA (ds-DNA) antibodies resistance index changes, traditional Chinese medicine (TCM) syndrome integral changes, and changes in serum cytokine indexes, blood rheology indexes, and T lymphocyte subsets indexes were observed. SLE changes in disease activity index (SLEDAI-2000), quality of life (SF-36) scores, and adverse reactions were explored. ResultThe total effective rate was 96.08% (49/51) in the observation group, higher than 84.31% (43/51) in the control group (χ2=3.991, P<0.05). The onset time, symptom improvement time, skin lesion regression time, and hospital stays in the observation group were shorter than those in the control group (P<0.05,P<0.01). Before treatment, erythrocyte sedimentation rate (ESR), platelet count (PLT), hemoglobin (HGB), white blood cell count (WBC), and other blood routine indexes, 24h urinary protein levels, anti-ds-DNA, TCM syndrome integral core, serum cytokine indexes including interleukin-4 (IL-4), IL-6, soluble interleukin-2 receptor (sIL-2R), blood rheology indexes (fibrinogen, plasma viscosity, and whole blood viscosity),T lymphocyte subsets indexes (CD4+, CD8+, and CD4+/CD8+), SLEDAI-2000, and SF-36 score comparison in both groups had no statistical significance. After treatment, the above indicators were improved in each group (P<0.05), and the indicators in the observation group was better than that in the control group (P<0.05). In terms of the adverse reactions, there was 1 case of digestive tract reaction, 1 case of elevated aminotransferase, and 1 case of insomnia in the observation group. There were 2 cases of digestive tract reaction,1 case of infection, and 1 case of elevated transaminase in the control group. The difference of the adverse reactions between the two groups had no statistical significance. ConclusionXijiao Dihuangtang combined with acupuncture has good clinical effect on the treatment of SLE with syndrome of intense heat toxin, and the method is safe, reliable, and worthy of application.

ABSTRACT

ObjectiveTo investigate the effect and mechanism of Mori Folium extract on the glucose and lipid metabolism disorders in the liver of rats with type 2 diabetes mellitus (T2DM) through the phosphatidylinositol 3-kinase/protein kinase B/peroxisome proliferation-activated receptor α/carnitine palmitoyl transferase-1 (PI3K/Akt/PPARα/CPT-1) signaling pathway. MethodThe T2DM model was induced by the high-fat diet combined with the intraperitoneal injection of streptozotocin (STZ). The model rats were randomly divided into a model group, a metformin (0.2 g·kg-1) group, and a Mori Folium water extract (4.0 g·kg-1) group according to blood glucose and body weight. In the 8-week administration, fasting blood glucose was measured at the same time every week. The histomorphological and fat changes in the rat liver were observed by hematoxylin-eosin (HE) staining and oil red O staining. The levels of total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) in the serum were measured by biochemical methods. Western blot (WB) was used to quantitatively detect the protein expression of p-PI3K,PI3K,p-Akt,Akt,PPARα,and CPT-1 in the rat liver. ResultAfter 8-week administration, the blood glucose of rats was higher in the model group than that in the control group (P<0.01), and lower in the Mori Folium water extract group than that in the model group (P<0.01). The results of HE staining showed that the liver tissue structure of the control group was complete, and the hepatocytes were arranged radially around the central vein, while the hepatocyte injury in the model group was obvious. Compared with the model group, the Mori Folium water extract group showed improved vacuolar degeneration and no lesions such as small bile duct hyperplasia. Oil red O staining showed that there was no obvious steatosis and necrosis in the hepatocytes of rats in the control group, and no lipid droplets in the hepatocytes were observed, while the model group showed increased lipid droplets. Mori Folium significantly reduced the lipid droplets in the liver. Biochemical analysis showed that the levels of TC, TG, LDL-C, AST, and ALT in the model group were significantly higher than those in control group (P<0.01). The levels of TC, TG, LDL-C, AST, and ALT in the Mori Folium water extract group were significantly lower than those in the model group (P<0.05,P<0.01). WB showed that the protein expression of p-PI3K/PI3K, p-Akt/Akt, PPARα, and CPT-1 in the model group were lower than those in the control group (P<0.01). Mori Folium water extract could increase the protein expression of p-PI3K/PI3K, p-Akt/Akt, PPARα, and CPT-1 (P<0.05 or P<0.01). ConclusionThe hypoglycemic mechanism of Mori Folium water extract may be related to the regulation of the PI3K/Akt/PPARα/CPT-1 signaling pathway.

ABSTRACT

The COVID-19 pandemic is still ongoing in the world, the risk of COVID-19 spread from other countries or in the country will exist for a long term in China. In the routine prevention and control phase, a number of local COVID-19 epidemics have occurred in China, most COVID-19 cases were sporadic ones, but a few case clusters or outbreaks were reported. Winter and spring were the seasons with high incidences of the epidemics; border and port cities had higher risk for outbreaks. Active surveillance in key populations was an effective way for the early detection of the epidemics. Through a series of comprehensive prevention and control measures, including mass nucleic acid screening, close contact tracing and isolation, classified management of areas and groups at risk, wider social distancing and strict travel management, the local COVID-19 epidemics have been quickly and effectively controlled. The experiences obtained in the control of the local epidemics would benefit the routine prevention and control of COVID-19 in China. The occurrence of a series of COVID-19 case clusters or outbreaks has revealed the weakness or deficiencies in the COVID-19 prevention and control in China, so this paper suggests some measures for the improvement of the future prevention and control of COVID-19.

ABSTRACT

As one of the most serious hereditary neuromuscular disease, spinal muscular atrophy (SMA) is caused by the loss or mutation of survival motor neuron 1 (SMN1) gene. It leads to a decrease in the level of SMN protein and a consequent loss of alpha neurons and progressive muscle atrophy resulting in the progressive muscle weakness, the significant disability and the shortened lifespan. Up till now, only three drugs have been approved for SMA, including the gene therapy drug onasemnogene abeparvovec. The antisense oligonucleotide drug nusinersen and and the small molecule chemical drug risdiplam were briefly introduced. Some representative samples of the small molecule chemical drugs and antisense oligonucleotide drugs targeting SMN2 in the clinical trial or preclinical research phases were also reviewed.

ABSTRACT

We explored the mechanism of patchouli oil in the treatment of inflammatory bowel disease (IBD) based on network pharmacology and differentially expressed genes in macrophages. The chemical composition of patchouli oil was detected by GC-MS, targets for active components were collected through TCMSP and Swiss Target Prediction platform, and targets for treatment of IBD were retrieved from DrugBank, GeneCards, OMIM, PharmGkb, and TTD databases. The intersection targets were merged, Cytoscape software was used to construct the "component-to-intersection target" network, and protein-protein interaction (PPI) network was drawn with String platform. The intersection targets were enriched for GO and KEGG enrichment analysis on Metascape platform, and the molecular docking of AutoDock Vina was used to verify the analysis results. The macrophage chip data was downloaded, and the differential genes were obtained by using R software. KEGG signaling pathway analysis of differentially expressed genes were performed by DAVID platform. Real-time fluorescence quantitative PCR was used to verify the screened components in the cell model in vitro. The 14 main components of patchouli oil corresponded to 112 targets, and the intersection obtained 97 common targets of patchouli oil for IBD treatment. GO enrichment analysis yielded 53 items. Eighteen items were obtained by KEGG enrichment analysis, involving cAMP signaling pathway, Notch signaling pathway, adhesion connection, Th17 cell differentiation and other signaling pathways. Molecular docking showed that the selected active components of patchouli oil had good binding activity with the targets. Differentially expressed genes were enriched in inflammatory pathways such as Toll-like receptors, JAK-STAT and NF-κB signaling pathways. q-PCR showed that patchouli oil, patchouli alcohol, pogostone can reduce the mRNA levels of cytokines (TNF-α, IL-1β, IL-6, and IL-23) and up-regulate the mRNA levels of tight junction proteins (occludin and claudin-1) in the inflammatory model of NCM460 normal colon epithelial cells. Patchouli alcohol can significantly reduce the levels of TNF-α, IL-6, and IL-1β inflammatory factors in RAW264.7 macrophages induced by LPS. This study revealed the multi-component, multi-target and multi-pathway of patchouli oil, and confirms the anti-inflammatory effect of patchouli oil and its main components in the inflammatory cell model in vitro and the protection of intestinal epithelial barrier integrity function, which provides a theoretical basis for further elucidating the mechanism of patchouli oil in the treatment of IBD.

Objective:To study the clinical effect of Qinghao Fuzheng Jiedu decoction on systemic lupus erythematous (SLE). Method:A total of 109 SLE patients admitted to the Rheumatology and Immunology Department of Wuhan No. 1 Hospital from December 2019 to October 2020 were selected and divided into an observation group (55 cases) and a control group (54 cases) using the random number table. Two cases in the observation group dropped out, leaving a total sample of 53, and one case in the control group dropped out, with 53 cases finally included. Patients in the control group were treated with prednisone tablet and azathioprine. On this basis, those in the observation group further received Qinghao Fuzheng Jiedu decoction. The clinical efficacy, traditional Chinese medicine (TCM) syndrome score, TCM syndrome efficacy, immunoglobulin (Ig) G, IgA, IgM, and complements C3 and C4 of the two groups were compared. The conversion of positive antinuclear antibody (ANA) and anti-double-stranded deoxyribonucleic acid antibody (DS-DNA) titers to negative in two groups after treatment was analyzed. Result:The total clinical efficacy rate of the observation group was significantly higher than that of control group (92.45% vs 73.58%,<italic>χ<sup>2</sup></italic>=6.692,<italic>P</italic><0.05). Before treatment, there were no significant differences in IgG, IgA, IgM, complements C3 and C4, and serum ANA and ds-DNA titers between two groups. After treatment, the levels of IgG, IgA, and IgM and serum ANA and ds-DNA titers in both groups obviously declined, whereas the levels of complements C3 and C4 rose (<italic>P</italic><0.05). Besides, the levels of IgG, IgA, and IgM and serum ANA and ds-DNA titers in the observation group were lower than those in the control group, while the levels of complements C3 and C4 were higher (<italic>P</italic><0.05). The negative rates of ANA and ds-DNA in observation group were significantly higher than those in control group (<italic>χ<sup>2</sup></italic>=8.040,<italic>P</italic><0.05). TCM syndrome scores were decreased in both groups after treatment (<italic>P</italic><0.05), and the score in observation group was lower than that in control group (<italic>P</italic><0.05). In terms of TCM syndrome efficacy, the total effective rate of observation group was significantly increased as compared with that of the control group (94.34% vs 50.94%,<italic>χ<sup>2</sup></italic>=25.112,<italic>P</italic><0.05).

ABSTRACT

Mild cognitive impairment (MCI) is a pre-clinical stage of Alzheimer's disease (AD). In recent years, transcranial direct current stimulation (tDCS), as a neuromodulation technique, has being applied in the field of cognitive intervention for MCI, but its effect is controversial because of many factors. In order to promote the application of tDCS in intervention for MCI, this study performed a systematic review of the previous studies that used tDCS to improve cognitive functions of MCI individuals. The results indicate that tDCS could improve episodic memory, working memory, and language of individuals with MCI, while there is a lack of strong evidence that supports a positive effect of tDCS on attention of individuals with MCI. The placement of electrodes, time course of treatment, and current intensity all affected the intervention effect of tDCS. Future studies should take brain networks underlying cognitive processes and personalized factors such as age and education level into consideration to design better stimulation protocols, and they should be conducted in combination with neuroimaging technologies to evaluate the intervention effect of tDCS more accurately and objectively and to discover the neural mechanisms of tDCS intervention.

ABSTRACT

OBJECTIVE@#To investigate the cardioprotective effect of Danqi Tablet (DQT, ) on ischemic heart model rats and the regulative effect on energy metabolism through peroxisome proliferator-activated receptor-γ coactivator-1α (PGC-1α).@*METHODS@#Rat ischemic heart model was induced by ligation of left anterior descending coronary artery. Totally 40 Sprague-Dawley rats were randomly divided into sham group, model group, DQT group (1.5 mg/kg daily) and trimetazidine (TMZ) group (6.3 mg/kg daily) according to a random number table, 10 rats in each group. Twenty-eight days after continuous administration, cardiac function was assessed by echocardiography and the structures of myocardial cells were observed by hematoxylin-eosin staining. The level of adenosine triphosphate (ATP) in myocardial cells was measured by ATP assay kit. Expressions level of key transcriptional regulators, including PGC-1α, Sirtuin 1 (SIRT1), AMP-activated protein kinase (AMPK), and downstream targets of PGC-1α, such as mitofusin 1 (MFN1), mitofusin 2 (MFN2) and superoxide dismutase 2 (SOD2) were measured by Western blot. Expression level of PGC-1α was examined by immunohistochemical staining.@*RESULTS@#The rat ischemic heart model was successfully induced and the heart function in model group was compromised. Compared with the model group, DQT exerted cardioprotective effects, up-regulated the ATP production in myocardial cells and inhibited the infiltration of inflammatory cells in the margin area of infarction of the myocardial tissues (P<0.01). The expressions of PGC-1α, SIRT1 and AMPK were increased in the DQT group (all P<0.05). Furthermore, the downstream targets, including MFN1, MFN2 and SOD2 were up-regulated (P<0.05 or P<0.01). Compared with the TMZ group, the expression levels of PGC-1α, MFN1 and SOD2 were increased by DQT treatment (P<0.05 or P<0.01).@*CONCLUSION@#DQT regulated energy metabolism in rats with ischemic heart model through AMPK/SIRT1 -PGC-1α pathway. PGC-1α might serve as a promising target in the treatment of ischemic heart disease.

ABSTRACT

Objective : To establish a practical data-driven method that helps predict the evolutionary trend of the coronavirus disease 2019 (COVID-19) epidemic, track and prejudge the current risk classification of the epidemic area, and provide a quantitative evidence for precision prevention and control strategies. Methods ¡¤ A moving average prediction limit (MAPL) method was established based on the moving average method. The previous severe acute respiratory syndrome (SARS) epidemic data was used to verify the practicability of the MAPL method for predicting epidemic trends and quantitative risk. By tracking the COVID-19 outbreak epidemic data publicly reported since January 16, 2020, the MAPL method was used for timely epidemic trend prediction and the risk classification. Results ¡¤ According to the MAPL analysis, the na-tional epidemic of COVID-19 peaked in early February 2020. After active prevention and control in early stages, the overall epidemic situation in the country showed a downward trend from mid-February to mid-March. Compared with Hubei Province, the number of new cases in non-Hubei region declined rapidly in mid-February, but then increased slightly. The analysis of imported cases since March showed that there was a medium to high level of epidemic import risk in the near future. It is recommended to take corresponding prevention and control measures to prevent the epidemic from spreading again. Conclusion ¡¤ The MAPL method can assist in judging the epidemic trend of emerging infectious diseases and predicting the risk levels in a timely manner. Each epidemic district may implement a differentiated precision prevention and control strategies according to the local classification of epidemic risk. Since March, attention should be paid to the prevention and control of imported risks.

ABSTRACT

To evaluate the exported risk of novel coronavirus pneumonia (NCP) from Hubei Province and the imported risk in various provinces across China. Data of reported NCP cases and Baidu Migration Indexin all provinces of the country as of February 14, 2020 were collected. The correlation analysis between cumulative number of reported cases and the migration index from Hubei was performed, and the imported risks from Hubei to different provinces across China were further evaluated. A total of 49 970 confirmed cases were reported nationwide, of which 37 884 were in Hubei Province. The average daily migration index from Hubei to other provinces was 312.09, Wuhan and other cities in Hubei were 117.95 and 194.16, respectively. The cumulative NCP cases of provinces was positively correlated with the migration index derived from Hubei province, also in Wuhan and other cities in Hubei, with correlation coefficients of 0.84, 0.84, and 0.81. In linear model, population migration from Hubei Province, Wuhan and other cities in Hubei account for 71.2%, 70.1%, and 66.3% of the variation, respectively. The period of high exported risk from Hubei occurred before January 27, of which the risks before January 23 mainly came from Wuhan, and then mainly from other cities in Hubei. Hunan Province, Henan Province and Guangdong Province ranked the top three in terms of cumulative imported risk (the cumulative risk indices were 58.61, 54.75 and 49.62 respectively). The epidemic in each province was mainly caused by the importation of Hubei Province. Taking measures such as restricting the migration of population in Hubei Province and strengthening quarantine measures for immigrants from Hubei Province may greatly reduce the risk of continued spread of the epidemic.

ABSTRACT

OBJECTIVE@#To compare the effect of Sheng-Xue-Xiao-Ban Capsule (SXXBC) and indirubin to the peripheral platelets of the Idiopathic thrombocytopenic purpura (ITP) model mouse.@*METHODS@#The ITP mouse model was established by the method of passive immunization. SXXBC and indirubin were used for intervention treatment. Then the hemorrhagic phenomena of ITP mice were observed and the numbers of peripheral platelets, hemoglobin and white blood cells, bone marrow megakaryocytes and their classification and coagulation function were detected and compared.@*RESULTS@#The improvement rate of hemorrhage in SXXBC group was 40% for small dose, 60% for medium dose and 80% for high dose, while the improvement rate of hemorrhage in indirubin group was 30% for small dose, 50% for medium dose and 60% for high dose. There was no statistically significant difference in the improvement rate of hemorrhage between the two groups (P>0.05). Compared with the model control group, PLT and Hb increased in different doses of SXXBC and indirubin group 4th-8th day after drug intervention (P<0.05, 0.01). However, there was no significant difference between the different doses of SXXBC group and indirubin group (P>0.05). Compared with the model control group, the WBC in each group was significantly lower (P<0.05, 0.01) on the 4th-8th day after drug intervention; However, there was no statistical significance between the two groups of SXXBC and indirubin (P>0.05). Compared with the model control group, the total number of megakaryocytes in each treatment group were decreased (P<0.05, P<0.01), in which the number of primary megakaryocytes in the large and medium dose groups of SXXBC and indirubin were decreased (P<0.05, 0.01), and the number of juvenile megakaryocytes in the large dose group of SXXBC and indirubin were also decreased (P<0.05). The number of granular megakaryocytes were decreased in each intervention groups (P<0.05, 0.01), and the number of thromocytogenic megakaryocyte was increased in the high and medium dose groups of SXXBC and indirubin (P<0.01). The time of prothrombin was shortened in the high and medium dose groups of SXXBC and indirubin (P<0.05), and the fibrinogen (FIB) content in the high and medium dose groups of SXXBC was close to that of the normal control group.@*CONCLUSION@#Both of the SXXBC and the indirubin standard all show good hemostatic effects. Indirubin shows a positive effect on increasing the peripheral platelet and hemoglobin in ITP model mice, regulating the immune response, reducing the total number of bone marrow megakaryocytes, increasing the thromocytogenic megakaryocyte, and increasing coagulation function.

ABSTRACT

Compared with age-matched controls,mild cognitive impairment (MCI) populations are at a higher risk of developing Alzheimer's disease (AD).There is no consensus that any pharmacological treatment can improve MCI,thus it is plausible to turn attention to cognitive interventions.This paper reviewed the prior researches on cognitive stimulation,cognitive training,and cognitive rehabilitation for MCI based on the categories defined by Clare and Woods in order to clarify the effect of these interventions on improving cognitive function in MCI individuals.The results indicate that cognitive interventions may improve multiple cognitive domains including memory performance,executive functions,processing speed,attention,and social functions in adults with MCI,while the mechanism remains unclear.It suggested that further studies should examine the mechanism of cognitive intervention by applying neuroscience technology and strengthening the control of heterogeneity of the etiologies and symptoms of MCI,and improve the clinical effect by combining cognitive stimulation,cognitive training,and cognitive rehabilitation.

ABSTRACT

Human monocyte is an important cell type which is involved in various complex human diseases. To better understand the biology of human monocytes and facilitate further studies, we developed the first comprehensive proteome knowledge base specifically for human monocytes by integrating both in vivo and in vitro datasets. The top 2000 expressed genes from in vitro datasets and 779 genes from in vivo experiments were integrated into this study. Altogether, a total of 2237 unique monocyte-expressed genes were cataloged. Biological functions of these monocyte-expressed genes were annotated and classified via Gene Ontology (GO) analysis. Furthermore, by extracting the overlapped genes from in vivo and in vitro datasets, a core gene list including 541 unique genes was generated. Based on the core gene list, further gene-disease associations, pathway and network analyses were performed. Data analyses based on multiple bioinformatics tools produced a large body of biologically meaningful information, and revealed a number of genes such as SAMHD1, G6PD, GPD2 and ENO1, which have been reported to be related to immune response, blood biology, bone remodeling, and cancer respectively. As a unique resource, this study can serve as a reference map for future in-depth research on monocytes biology and monocyte-involved human diseases.

ABSTRACT

The ethyl acetate extract of Euphorbia lunulata Bge was separated and researched on anticancer activity about it with in vitro cell experiments,in order to provide a theoretical basis for the exploit and utilization of E.lunulata and more options to develop natural anticancer drugs.Quercetin and Gallic Acid in ethyl acetate were extracted by HPLC,which the ethyl acetate extract of E.lunulata was separated and extracted by solvent system.The MTT was used to measure the inhibition of each component with different concentration from ethyl acetate extract to the 2R-75-30 breast cancer cell.The results showed that Quercetin and Galic Acid of ethyl acetate extract were 19.99% and 55.04%,respectively.There were 17 component from the ethyl acetate extract,and finally merged into six fractions.Each component (the concentration of 50 μg/ml-150 μg/ml range) from ethyl acetate extract of E.lunulata could inhibit the growth of ZR-75-30 breast cancer cell.And a certain gradient relationship with the drug concentration increased with the inhibition rate enhancement on the 2R-75-30 breast cancer cell's growth.The 2nd fraction showed the highest activity.It was concluded that there were flavonoids and phenolic acids in ethyl acetate extract.Each component from the extract showed inhibition on the growth of breast cancer cell if it was further separated.This study was designed to provide a theoretical basis to exploit the anticancer drugs from E.lunulata.

ABSTRACT

Objective Reports are relatively few at home and abroad onrobot-assistedlaparoscopic ureteral reimplantation ( RAUR) .This study summarizes our experience with RAUR and assesses the feasibility and clinical effect of the strategy . Methods We retrospectively analyzed the clinical data about 5 cases of lower ureterostenosistreated by RAUR in our department from May 2015 to February 2017. Results Operations were successfully completed in all the cases , with an estimatedintraoperative blood loss of 40-100 mL but no blood transfusion , nor conversion to open surgery , nor intestinal or major vascular injury .The urethral catheter was re-moved at 5-7 days after surgery and there were no postoperative complications .The patients were followed up for over 6 months , during which all showed increased glomerular filtration rate ( 2-12 mL/min) of the involved kidney at 3 months and ultrasonography revealed no ureterostenosisorhydronephrosis . Conclusion Robot-assistedlaparoscopic ureteral reimplantation is a safe , effective and minimally invasive surgical option for distal ureteral obstruction .
