Objective: To observe the effect of oxymatrine ointment on chronic eczema in mice, and preliminarily explore the mechanism. Methods:Thirty-two Kunming mice were randomly divided into four groups including oxymatrine ointment group, blank model group, blank ointment group and positive drug group treated with compound dexamethasone acetate cream. Eczema skin was con-tinuously treated with drugs for 14 days. The mice were sacrificed on the 15th day, and the eczema skin was clipped from back to make histological sections. The changes of inflammation were observed, and the inflammatory cell count was obtained. Meanwhile, heart blood was collected, and serum was obtained by centrifugation. The serum levels of IL-4 and IL-1β were determined by ELISA. Re-sults:The inflammatory cell count in oxymatrine ointment group and the positive drug group was lower than that in the blank model group and the blank ointment group (P<0. 05). The pathology results showed that oxymatrine ointment could improve chronic eczema symptoms, reduce the inflammatory cell infiltration and decrease edema, which was similar to the effects of compound dexamethasone acetate cream. In the respect of molecular immunology, the IL-4 and IL-1βlevels in serum showed no significant changes in oxymatrine ointment group (P>0. 05). Conclusion: Oxymatrine ointment has certain anti-inflammatory effect on eczema, and the mechanism needs to be studied further.

Objective To investigate the safety and feasibility of fast track surgery (FTS)in patients with vaginal hysterectomy for non -prolapsed uterus.Methods 1 1 0 cases of vaginal hysterectomy for non -prolapsed ute-rus with benign uterine disease were randomly divided into two groups:fast track group (n =55)and conventional group (n =55).The operative time,intraoperative blood loss,postoperative nausea and vomiting,anal exhaust time, postoperative hospital stay,medical cost and perioperative complications were compared between the two groups. Results In FTS group,the incidence rate of postoperative nausea and vomiting,the postoperative anal exhaust time, hospital stay,cost of hospitalization were 1 6.4%,(1 3.73 ±2.41 )h and (4.38 ±1 .08 )d,(7 541 .00 ± 253.1 7)yuan,respectively,which in the control group were 36.4%,(1 8.56 ±1 .54 )h,(4.89 ±1 .26 )d, (8 1 55.1 5 ±495.89)yuan,the differences were statistically significant between the two groups (χ2 =5.67,t =-1 2.53,-2.28,-8.1 7,all P <0.05).There was no significant difference in the operative complications between the two groups (P >0.05).Conclusion FTS has good security.It can short the hospitalization time,reduce medical costs and improve the quality of life in patients who underwent vaginal hysterectomy for non -prolapsed uterus with benign uterine disease.

Objective To evaluate the clinical efficacy and safety of transcatheter arterial chemoembolization (TACE) with oxaliplatin (OXA), fluorouracil (5-Fu) and pirarubicin (THP) scheme in treating primary liver cancer. Methods A total of 65 patients with primary liver cancer were treated with TACE using infusion of OXA/5-Fu/THP scheme (TACE group). Other 21 patients with primary liver cancer, who were encountered at the Department of Interventional Radiology of authors’ hospital during the same period as the patients of TACE group, received simple transarterial embolization (TAE group). The therapeutic effect, the occurrence of adverse reactions, the progression-free survival time (PFS) and overall survival time (OS) of the two groups were comprehensively evaluated. The results were compared between the two groups. Results In the TACE group, the objective response rate (ORR) and disease control rate (DCR) were 55.4%and 81.5%respectively, and the median PFS and median OS were 11.5 months and 18.5 months respectively. Single factor analysis indicated that patients, who had liver function of Child-Pugh A and received more times or treatment, and who had small-sized tumor and no portal vein tumor thrombus or metastasis, usually had a better prognosis, and the differences were statistically significant (P<0.05). The prognosis of the patients with Barcelona staging (BCLC) B was better than that of the patients with Barcelona staging C, and the difference was statistically significant (P=0.000). Cox multivariate analysis revealed that the portal vein tumor thrombus and tumor metastasis were independent risk factors for the prognosis of the patients. Compared with the TAE group, TACE with OXA/5-Fu/THP scheme could effectively improve the mean progression-free survival time. Conclusion For the treatment of primary liver cancer, TACE with infusion of OXA/5-Fu/THP is clinically effective with fewer adverse reactions.

[Objective] To investigate the role SPAG5 play in ovarian adenocarcinoma cell mitosis,Taxol sensitivity and ovarian high grade serous carcinoma patients' prognosis.[Methods] Transient knockdown of SPAG5 in SKOV3 cell were performed,and MTT assay and cell cycle flow cytometry assay were carried out.IHC staining of SPAG5 protein in 110 high grade serous carcinoma patients' tumor tissues were performed,and the expression were analyzed with clinical data and prognosis.Finally,SPAG5 were knocked down in OVCAR3 A2780 and SKOV3 cells followed by 0.5μM Taxol treatment,MTT assay were performed to detect cell viability.[Results] SPAG5 knockdown inhibited cell mitosis of ovarian adenocarcinoma cell SKOV3 by G2/M arrest.High grade serous carcinoma patients after neoadjuvant chemotherapy gained the expression of SPAG5.Patients without neoadjuvant chemotherapy with low SPAG5 expression have poor progress free survival,especially in early stage patients.Patients with low SPAG5 expression also have poorer overall survival,but the difference was not statistically significant.Furthermore,SPAG5 knockdown in OVCAR3 A2780 and SKOV3 cells reduced Taxol sensitivity.[Conclusion] SPAG5 regulated cell mitosis and promoted cell proliferation in ovarian adenocarcinoma cell lines.Expression of SPAG5 in patients' tumor tissues predicted patients' prognosis and Taxol sensitivity.As the results,individualized treatment of high grade serous carcinoma patients is necessary.

Objective To examine the prevalence of chikungunya virus in brain tissue samples from rat?like animals in Xiamen, Shenzhen and Guangzhou, and to explore whether the rat?like animals are potential sources of human chikungunya fever infections and the host of the virus. Methods Rat?like animals were trapped in residential areas, city parks, hospitals, markets and schools in Xiamen, Shenzhen and Guangzhou (Yuexiu and Baiyun districts) between January 2013 and June 2016. Brain tissue samples of the trapped animals were collected under sterile. Chikungunya virus was detected by using reverse transcription polymerase chain reaction (RT?PCR). Results Totally 1092 rat?like animals were trapped, which belonged to 7 species, 3 genera, 2 families, 2 orders. Rattus norvegicus was the dominant species in the indoor environment, Rattus losea was dominant in wild environment, and 1092 brain tissue samples were collected. No detectable chikungunya virus was found in the brain tissue samples by RT?PCR. Conclusion There is a low possibility that rat?like animals act infectious sources of human chikungunya fever infections and the host of the virus.

Objective:To investigate the effect of fluorofenidone on renal interstitial fibrosis in rats with unilateral ureteral obstruction (UUO) and to observe the effect of fluorofenidone on the expressions of collagen type Ⅰ (Col Ⅰ),collagen type Ⅲ (Col Ⅲ),α-smooth muscle actin (α-SMA),connective tissue growth factor (CTGF),platelet derived growth factor (PDGF) in the renal tissues of UUO rats.Methods:Male Sprague-Dawley (SD) rats were randomly divided into a sham-operated group,a UUO group,and a flurofenidone group (n=5).UUO model was induced by ligating the left ureter in rats.The rats were treated with 125 mg/(kg.d) fluorofenidone by gastric gavage in the fluorofenidone group at 24 h before the operation,and the rats were treated with the identical dose of 0.5％ sodium carboxyl methyl cellulose (CMC-Na) in the other 2 groups.The rats were sacrificed at 14 days after UUO.Pathological changes of the renal tissue were observed by HE and Masson staining,the mRNA expressions of Col Ⅰ,Col Ⅲ,α-SMA,PDGF and CTGF were detected by real-time PCR,and the protein expressions of Col Ⅰ,Col Ⅲ,PDGF and CTGF were detected by immunohistochemical staining.Results:The renal interstitial damage index,relative collagen area and mRNA and protein expressions of Col Ⅰ and Col Ⅲ in the renal tissues of the rats in the UUO group significantly increased (P＜0.05),and fluorofenidone could reduce these indexes (P＜0.05).Compared with the sham-operated group,the protein expressions ofα-SMA,PDGF,CTGF and the mRNA expressions of PDGF and CTGF in the renal tissues of the rats in the UUO group were increased,but fluorofenidone could decrease the protein expressions of α-SMA,PDGF,CTGF and the mRNA expressions of PDGF and CTGF (P＜0.05).Conclusion:Fluorofenidone (125 mg/kg·d) could attenuate renal interstitial fibrosis through inhibition offibroblast proliferation,myofibroblastic activation,PDGF and CTGF expression.

Objective:To explore the key genes and pathways that may play an important role in the pathogenesis of acne by bioinformatics analysis.Methods:GSE6475 and GSE53795 datasets were collected from GEO database, and 18 acne lesions tissues and 18 normal skin tissues were compared. David database was used to analyze the gene ontology (GO) and the key pathway (Kyoto Encyclopedia of genes and genomes, KEGG) of the differential genes, to establish the protein interaction network of the differential genes, and to obtain the most relevant key genes and important clusters.Results:A total of 314 up-regulated genes and 62 down-regulated genes were filtered from those GEO profiles. KEGG pathway analysis showed that these differential genes were mainly enriched in Staphylococcus aureus infection, osteoclast differentiation, pentose and glucuronate interconversions. In addition, 379 nodes and ten key genes (CXCL8, PTPRC, IL1B, ITGB2, CXCR4, ICAM1, CCR5, SELL, C3AR1 and PLEK) were screened out by protein interaction network.Conclusions:The key genes and pathways identified in this study may be new targets for intervention in the development of acne.

OBJECTIVETo compare the prevalence of hypertension between low birth weight infant (LBWI) women and non-LBWI women.

METHODSA retrospective cohort study was applied and 3 172 pregnant women giving births during October 1976 to December 2008 in our hospital and underwent physical check-up between 2010 and 2011 at the Kailuan medical group were included and divided into LBWI group and non-LBWI group by the history of LBWI. Prevalence of hypertension was obtained during the follow-up program. Multiple logistic regression analysis was used to assess the relative risk of hypertension.

RESULTSA total number of 3 172 women, with an average age of 42.3 years old were divided into LBWI group (n = 147) and non-LBWI group (n = 3 025), with the average birth weights of their infants were 2.31 kg and 3.39 kg, respectively. The prevalence of hypertension from the follow-up program was significantly higher in LBWI group than that in the non-LBWI group (23.8% vs. 16.9%, P < 0.05). After adjustment for other traditional risk factors, the risk of hypertension in LBWI group was 1.60 (95%CI:1.02-2.53) folds higher than that in the non-LBWI group.

CONCLUSIONPrevalence of hypertension in women with LBWI was higher than that in those women without LBWI. History of LBWI seemed to have had an increased risk to develop hypertension.

ObjectiveTo investigate the effect and mechanism of Dendrobium mixture （DMix）-containing serum on high glucose-induced podocyte injury in mice. MethodThe MPC5 mouse glomerular podocytes were cultured in vitro， and the optimal glucose concentration for modeling， modeling time， and concentration of DMix-containing serum for administration were determined. The cells were classified into normal （5.5 mmol·L^-1 glucose+10% blank serum）， model （30 mmol·L^-1 glucose+10% blank serum）， DMix-containing serum （30 mmol·L^-1 glucose+10% DMix-containing serum）， ferroptosis inhibitor （Fer-1， 30 mmol·L^-1 glucose+10% blank serum+1 μmol·L^-1 Fer-1） groups. The corresponding kits were used to measure the levels of Fe²⁺ and lactate dehydrogenase （LDH） in cells. Enzyme-linked immunosorbent assay was employed to determine the content of glutathione （GSH） and lipid peroxide （LPO） in cells. Fluorescence probe was used to measure the reactive oxygen species （ROS） level. Real-time fluorescence quantitative polymerase chain reaction and Western blotting were employed to determine the mRNA and protein levels， respectively， of Wilms' tumor-1 （WT-1）， desmin， long chain acyl-CoA synthase 4 （ACSL4）， and glutathione peroxidase 4 （GPX4） in podocytes. ResultCompared with the blank group， the intervention with 30 mmol·L^-1 glucose for 48 h reduced podocyte viability （P<0.01）， and the 10% DMix-containing serum showed the most significant improvement in podocyte viability （P<0.01）. Compared with the normal group， the model group presented elevated levels of Fe²⁺， LDH， LPO， and ROS， lowered GSH level， up-regulated mRNA and protein levels of desmin and ACSL4， and down-regulated mRNA and protein levels of WT-1 and GPX4 （P<0.01）. Compared with the model group， the DMix-containing serum lowered the Fe²⁺， LDH， LPO， and ROS levels， elevated the GSH level， down-regulated the mRNA and protein levels of desmin and ACSL4， and up-regulated the mRNA and protein levels of WT-1 and GPX4 in podocytes （P<0.05， P<0.01）. ConclusionDMix-containing serum exerts a protective effect on high glucose-induced podocyte injury by inhibiting ferroptosis.

[Abstract] Objective： ： To explore the impact of γ-chain (γc) family cytokines (IL-2, IL-7, IL-15, IL-21) on T cell phenotypes in ex vivo culture to provide experimental evidence for ex vivo cell preparation in adoptive immunotherapy. Methods: Peripheral blood mononuclear cells (PBMCs) were isolated from peripheral blood of healthy volunteers; nylon column sorting, CD3+ magnetic beads sorting, CD3- magnetic beads sorting and natural sedimentation were used to sort T cells from PBMCs. The purity, recovery rate and viability of T cells sorted by the above methods were compared. The CD3/CD28 magnetic beads-activated CD3+T cells were cultured inAIMV medium with IL-2 or mixed cytokines (IL-7, IL-15, IL-21). The expansion fold and phenotypes of T cells in ex vivo culture were detected by flow cytometry. Results： ： The purity of T cells sorted by CD3- magnetic beads sorting was significantly higher than that sorted by nylon column, CD3+ magnetic beads sorting and natural sedimentation ([94.06±1.07]% vs [86.74±1.06]%, [89.61±1.40]%, [88.48 ± 1.86]%, P<0.05); The recovery rate of T cells sorted by natural sedimentation was significantly higher than that by other three methods ([60.29±1.53]% vs [45.03±2.79]%, [20.15±3.41]%, [42.98±2.82]%, P<0.05). Comprehensively, the natural sedimentation method is the best option. The ex vivo expansion fold of T cells in IL-2 group was significantly higher than that in mixed group ([262.6±143.2] times vs [73.0±25.8] times, P<0.05). The proportions of early memory T cells, Tscm+Tscm-like and Tcmin the mixed group were significantly higher than those in the IL-2 group ([55.6±1.82]% vs [39.6±1.52]%, [16.6±1.82]% vs [9.8±1.30]%, [39.0±1.58]% vs [29.2±1.79]%; all P < 0.05). Conclusion： ： Natural sedimentation sorting has advantages of low cost, high recovery and purity. Mixed cytokines of IL-7, IL-15 and IL-21 are beneficial for production of early memory T cells. This study provides an experimental data of ex vivo T cell preparation for cancer adoptive immunotherapy.
