This study aims to explore the medication rules and mechanisms of treating chronic renal failure(CRF) by Jinling medical school based on data mining, network pharmacology, and experimental validation systematically and deeply. Firstly, the study selected the papers published by the inherited clinicians in Jinling medical school in Chinese journals using the subject headings named "traditional Chinese medicine(TCM) + chronic renal failure", "TCM + chronic renal inefficiency", or "TCM + consumptive disease" in China National Knowledge Infrastructure, Wanfang, and VIP Chinese Science and Technology Periodical Database and screened TCM formulas for treating CRF according to inclusion and exclusion criteria. The study analyzed the frequency of use of single TCM and the four properties, five tastes, channel tropism, and efficacy of TCM used with high frequency and performed association rule and clustering analysis, respectively. As a result, a total of 215 TCM formulas and 235 different single TCM were screened, respectively. The TCM used with high frequency included Astragali Radix, Rhei Radix et Rhizoma, Salviae Miltiorrhizae Radix et Rhizoma, Poria, and Atractylodis Macrocephalae Rhizoma(top 5). The single TCM characterized by "cold properties, sweet flavor, and restoring spleen channel" and the TCM with the efficacy of tonifying deficiency had the highest frequency of use, respectively. Then, the TCM with the rules of "blood-activating and stasis-removing" and "diuretic and dampness-penetrating" appeared. In addition, the core combination of TCM [(Hexin Formula, HXF)] included "Astragali Radix, Rhei Radix et Rhizoma, Poria, Salviae Miltiorrhizae Radix, and Angelicae Sinensis Radix". The network pharmacology analysis showed that HXF had 91 active compounds and 250 corresponding protein targets including prostaglandin-endoperoxide synthase 2(PTGS2), PTGS1, sodium voltage-gated channel alpha subunit 5(SCN5A), cholinergic receptor muscarinic 1(CHRM1), and heat shock protein 90 alpha family class A member 1(HSP90AA1)(top 5). Gene Ontology(GO) function analysis revealed that the core targets of HXF predominantly affected biological processes, cellular components, and molecular functions such as positive regulation of transcription by ribonucleic acid polymerase Ⅱ and DNA template transcription, formation of cytosol, nucleus, and plasma membrane, and identical protein binding and enzyme binding. Kyoto Encyclopedia of Genes and Genomes(KEGG) analysis revealed that CRF-related genes were involved in a variety of signaling pathways and cellular metabolic pathways, primarily involving "phosphatidylinositol 3-kinase(PI3K)-protein kinase B(Akt) pathway" and "advanced glycation end products-receptor for advanced glycation end products". Molecular docking results showed that the active components in HXF such as isomucronulatol 7-O-glucoside, betulinic acid, sitosterol, and przewaquinone B might be crucial in the treatment of CRF. Finally, a modified rat model with renal failure induced by adenine was used, and the in vivo experimental confirmation was performed based on the above-mentioned predictions. The results verify that HXF can regulate mitochondrial autophagy in the kidneys and the PI3K-Akt-mammalian target of rapamycin(mTOR) signaling pathway activation at upstream, so as to alleviate renal tubulointerstitial fibrosis and then delay the progression of CRF.

OBJECTIVES: To investigate the expression of apolipoprotein C1 (APOC1) in papillary thyroid carcinoma (PTC) and its effects on proliferation and apoptosis of PTC cells. METHODS: The expression level of APOC1 in PTC and its impact on prognosis were analyzed using GEPIA 2 and Kaplan-Meier databases. Immunohistochemistry (IHC) and Western blotting were used to detect the expression of APOC1 in PTC and adjacent tissues and in 3 PTC cell lines and normal thyroid Nthyori 3-1 cells. In TPC-1 and BCPAP cells, the effect of Lipofectamine 2000-mediated transfection with APOC1 siRNA or an APOC1-overexpressing plasmid on cell growth and colony formation ability were examined by observing the growth curves and using colony-forming assay. The changes in cell cycle and apoptosis of the transfected cells were analyzed with flow cytometry. RT-qPCR and Western blotting were used to detect the changes in expressions of P21, P27, CDK4, cyclin D1, Bcl-2, Bax, caspase-3 and caspase-9 and the key proteins in the JAK2/STAT3 signaling pathway. RESULTS: APOC1 expression was significantly higher in PTC tissues and the 3 PTC cell lines than in the adjacent tissues and Nthyori 3-1 cells, respectively. In TPC-1 and BCPAP cells, APOC1 knockdown obviously reduced cell proliferative activity, increased the percentage of G0/G1 phase cells, lowered the percentages of S and G2 phase cells, promoted cell apoptosis, and downregulated mRNA and protein expression levels of CDK4, cyclin D1 and Bcl-2 and the protein levels of p-JAK2 and p-STAT3. APOC1 overexpression in the cells produced the opposite effects on cell proliferation, apoptosis, cell cycle and the mRNA and protein expressions. The application of AG490, a JAK2 inhibitor, strongly attenuated APOC1 overexpression-induced activation of the JAK2/STAT3 signaling pathway in BCPAP cells. CONCLUSIONS APOC1 overexpression promotes proliferation and inhibits apoptosis of PTC cells possibly by activating the JAK2/STAT3 signaling pathway and accelerating cell cycle progression.

Methods? Using phenomenological research method, 24 women with gynecologic cancer were investigated by in-depth interview. Themes and sub-themes was extracted through content analysis. Results? Three kinds of specific supportive care needs were found, including specific symptom management needs, spousal relationship consolidation needs and self-esteem maintaining needs, and there existed gaps between patients identified needs and actual acquisition from health care personnel. Conclusions? Health care personnel should accurately assess the specific supportive care needs of patients with gynecologic cancer and then carry out targeted professional social support services to further meet patients' needs.

Objective To investigate the current status of job burnout among anesthetists in Ningxia and to analyze its related risk factors.Methods A total of 310 anesthetists from 30 public hospitals in Ningxia were conducted to collect data on the job burnout by Maslach Burnout InventoryHuman Services Survey (MBI-HSS).The factors associated with severe job burnout and its three domains (high emotional exhaustion,high depersonalization and low personal accomplishment) were included in the multinomial logistic regression analysis.Results The incidence of job burnout and its three domains (high emotional exhaustion,depersonalization and low personal accomplishment) were 18 (5.81％) cases,134 (43.22％) cases,35 (11.29％) cases and 128 (41.29％) cases,respectively.Multinomial logistic regression analysis results indicated that the risk degree associated with job burnout was master and higher degree (OR=4.695,95％CI 1.556-4.172).The risk facts associated with three components of job burnout were work time per week [40-60 h (OR=4.420,CI 2.504-7.802);≥60 h (OR =7.469,95％CI 1.758-31.733)] and tertiary hospital (OR =1.847,95％oCI 1.112-3.069);master and higher degree (OR=2.306,95％CI 1.032-5.155),working years [6-15 years (OR=0.358,95％CI 0.135-0.949)] and cases of anesthesia per year [≥390 cases (OR =3.352,95％CI 1.301-8.639)];secondary hospital (OR =1.717,95％CI 1.045-2.823).Conclusion This survey indicates that job burnout exists among anesthetists in Ningxia and is mainly displayed in emotional exhaustion and low personal accomplishment domains.Master and higher degree tend to occur serve job burnout.

Objective To explore the treatment of children with EB virus infection accompanied by facial paralysis. Method The clinical data of a child with EB virus infection accompanied by facial paralysis was analyzed retrospectively, and the related literature were reviewed. Results A 2-year-old boy was admitted to hospital due to fever and mouth askew for 4 days. After admission, he was confirmed to have EB virus infection and viremia by serology and polymerase chain reaction, and then treated with acyclovir. The symptoms of facial paralysis and EB viremia disappeared completely 14 days after antiviral treatment. There was no recurrence in the short-term follow-up. Interestingly, the literature analysis shows that there is still limited evidence for the antiviral treatment by acyclovir in children with acute infection of EB virus associated with facial paralysis. Conclusion Antiviral treatment may be beneficial to EB viremia with facial paralysis.

Objective To investigate whether lipopolysaccharide (LPS) can induce vascular endothelial cell growth factor (VEGF) expression in microglia regulated by hypoxia inducible factor-1α(HIF-1α). Methods The cultured BV2 cells were divided into four groups:control group, LPS (100 μg/L) simulated group, LPS (100 μg/L)+LPS antagonist (LRS, 200 μg/L) intervened group and LPS (100 μg/L)+HIF-1αinhibitors FM19G11 (10 mmol/L) intervened group. Immunofluorescence staining, Western blotting and ELISA were used to detect the expressions of VEGF and HIF-1α. Results Compared with the control group, the VEGF expression level was obvious high in LPS simulated group (P<0.05). LRS inhibited this effect of LPS (P<0.05). The HIF-1αlevel was increased in LPS simulated group at 8 h post-injury (P<0.05). FM19G11, the inhibitor of HIF-1αreduced the expression of VEGF induced by LPS (P<0.05). Conclusion LPS can up-regulate the expression of VEGF by HIF-1α.

To explore the optimized dispatch of the rescue resources based on the mastered resources informa-tion. The objective function was set as the shortest rescue time, and 0-1 programming models were established and solved for the conditions that the number of medical rescue units was more or less than needed by the missions. In the two conditions, the model's calculated results were both optimal, and could be used to obtain the optimal dispatch solutions while the medical rescue time was the shortest. The 0-1 programming model can be effectively used to optimize dispatch strategy for medical rescue team.

Objective To investigate the CT manifestations of gastric carcinoma invasion to lesser omentum and to assess the im-pact of lesser omentum on the spreading of gastric carcinoma.Methods We retrospectively reviewed CT findings in 48 patients with gastric carcinoma and lesser omentum involved for primary tumor and the lesser omentum abnormalities.The influence of lesser o-mentum on the extension of gastric carcinoma as well as the accompanied ascites were also analyzed.Results CT manifestations of lesser omentum involvement in gastric carcinoma included the following items:① direct infiltration (35.4%,1 7/48),which was mainly shown as increased density of fatty tissue and the development of mass within the lesser omentum,including spreading into the liver through the lesser omentum directly in two cases;② omental seeding (25.0%,12/48),including smudged appearance (1 1 cases)and omental caking (1 case);③ metastasis of lymph nodes (64.6%,31/48),including enlargement and increase of lymph nodes (27 cases)and cystic mass (4 cases).Ascites was found in 1 1 patients and fluid collection in the lesser sac was shown in 3 of these 1 1 patients.The lesser omentum forms the anterior wall of the lesser sac and separates the fluid collection in the lesser sac from the ascites in the greater peritoneal cavity.Ascites was associated with the omental seeding statistically.Conclusion CT scan is helpful for detecting lesser omentum invasion by gastric carcinoma.The imaging features consist of mass sign,enlargement of lymph nodes,smudged andcakingappearance,and so on.Lesser omentum may also play a certain role in both the extension of gastric carcinoma and the compartmentalization of ascites due to gastric carcinoma.
