Chinese Journal of Postgraduates of Medicine 2014;37(17):23-25
Objective To investigate the risk factors associated with surgical site infection (SSI) in patients with breast cancer,and provide the basis for preventing SSI.Methods Case-control study was used to investigate the clinical data of 630 patients of breast cancer retrospectively by single factor and multiple factors regressive analysis.Results The incidence rate of SSI was 3.65% (23/630),the main pathogenic bacteria was staphylococcus aureus (14/20),single factor regressive analysis showed that granulocytopenia associated with chemotherapy,diabetes mellitus,time of drainage were the risk factors of SSI (P < 0.05).Multiple factors regressive analysis showed that granulocytopenia associated with chemotherapy,time of drainage were the independent risk factors of SSI (P < 0.05).Conclusion Granulocytopenia associated with chemotherapy,time of drainage are the independent risk factors of SSI and comprehensive preventive measures should be taken to control the incidence rate of SSI.

Objective:To assess the effect of rosiglitazone on inflammation in peritoneal dialysis patients. Methods:Fifty patients undergoing continuous ambulatory peritoneal dialysis were collected in our hospital. The treatment group was assigned to receive regular peritoneal dialysis and rosiglitazone 4mg once daily while the control group was received regular peritoneal dialysis for 12 weeks. Such serum examinations as fasting blood glucose (FBG), glycosylated hemoglobin A1c, haemoglobin, serum total cholesterol, high density lipoprotein cholesterol(HDL-C), low density lipoprotein cholesterol, triglycerides and high sensitivity C reactive protein (hs-CRP) were measured, tumor necrosis factorα(TNF-α) and interleukin-6 (IL-6) levels were measured by ELISA, and homeostasis model as-sessment of insulin resistance( HOMA-IR) was also evaluated before and after the treatment. Results:After the 12-week treatment by rosiglitazone, the levels of FPG, HOMA-IR, hs-CRP, TNF-αand IL-6 were declined significantly(P<0. 05), and the level of HDL-C was increased significantly(P<0. 05). Conclusion: Rosiglitazone shows significant anti-inflammatory, insulin resistance improve-ment and anti-lipidemic effects in peritoneal dialysis patients.

Objective To study the expressions of apoptotic protease activating factor-1(Apaf-1)and astrocyte elevated gene-1(AEG-1)in colonic carcinoma,and to explore their correlations with the clinical path-ological features. Methods The expressions of Apaf-1 and AEG-1 were detected in 63 colonic carcinoma sam-ples and 30 normal colonic mucosa adjacent to tumor nest by immunohistochemical method,and their correla-tions with clinical features of colonic carcinoma were analyzed. Results The positive expressions of Apaf-1 and AEG-1 in colonic carcinoma were 23. 81%(15 / 63)and 68. 25%(43 / 63),respectively. The positive expre-ssions of Apaf-1 and AEG-1 in normal colonic mucosa were 76. 67%(23 / 30)and 26. 67%(8 / 30),respec-tively. The positive expression rate of AEG-1 was significantly higher in colonic carcinoma than that in normal tissue(χ2 = 14. 192,P = 0. 000). However,the expression of Apaf-1 was signi-ficantly lower in colonic carci-noma than that in normal tissue(χ2 = 23. 497,P = 0. 000). The expression of Apaf-1 was negatively correlated to the expression of AEG-1(r = - 0. 339,P = 0. 007). The expressions of AEG-1 and Apaf-1 were associated with differentiation degree(χ2 = 4. 643,P = 0. 031;χ2 = 12. 034,P = 0. 001)and clinical stage(χ2 = 6. 628, P = 0. 010;χ2 = 8. 246,P = 0. 004),but they were not correlated with age(χ2 = 1. 462,P = 0. 227;χ2 =2. 401,P = 0. 121)and tumor size(χ2 = 0. 333,P = 0. 564;χ2 = 0. 590,P = 0. 442). Conclusion The expression of AEG-1 is up-regulated in colonic carcinoma,but the expression of Apaf-1 is down-regulated,with a significant negative correlation. Apaf-1 and AEG-1 may be closely related to the occurrence and development of colon carcinoma. Therefore,combination detection of Apaf-1 and AEG-1 may be more valuable for the prog-nosis evaluation of colonic carcinoma.

The rotary cell culture system(RCCS)was used to simulate the microgravity environment, and FRTL-5 cells were divided into simulated microgravity group(SMG)and normal gravity group(NG). FRTL-5 cells were harvested after treatment for 6, 12, 24, and 36 h, the cell viability was measured by MTT assay, and the cells cycles were detected by flow cytometry. The ultrastructure of FRTL-5 cells was observed under laser confocal microscope with FITC-labeled technique. The MTT assay showed that the proliferation of FRTL-5 cells was significantly inhibited after RCCS treatment for 6, 12, 24, and 36h compared with NG(

Objective To investigate the effects of simulated microgravity by RCCS on proliferation and cell cytoskeleton of human HaCaT keratinocyte. Methods The rotary cell culture system (RCCS) was used to simulate the microgravity environment, and human HaCaT keratinocytes were divided randomly(random number) into the simulated microgravity group (SMG) and normal gravity group (NG). HaCaT cells in the two groups were harvested respectively after 32, 36 and 42 h culture. The HaCaT cells proliferation and cycles were detected by flow cytometry, the concentration of hb-EGF in supernatant was detected by ELISA, and the cell cytoskeleton was observed after 42 hours' culture under laser confocal microscope with FITC-labeled technique. SPSS 23.0 statistical software was used for statistical analysis, and P <0.05 was considered statistically significant. Results The flow cytometry showed that the proportions of human HaCaT keratinocytes in G1 and G2/M phases were increased while the proportion of HaCaT cells in S stage was decreased significantly after 32, 36 and 42 h RCCSculture compared with those in the normal gravity group. The HaCaT cells in G1 stage were declined along with incubation time. ELISA results showed that the hb-EGF concentration in HaCaT supernatant under simulated microgravity culture for 24 and 36 h was lower than that in the normal control group (P<0.01). The laser confocal microscope revealed that the HaCaT fluorescence intensity was decreased,and there were disordered microfilaments, structural ambiguity, pseudopodia reduction and irregularshape among FITC-labeled HaCaT cells cultured 42 h in RSSC compared with the normal gravity group.Conclusions RCCS simulated microgravity environment could inhibit the cell cycle transformation and proliferation of human HaCaT keratinocyte, affect the keratinocyte-secreting function, and induce alterations of the cell cytoskeleton.

Objective Stereotactic body radiotherapy(SBRT)and radiofrequency ablation(RFA)are primary treatments for hepatocellular carcinoma(HCC)at present.However,the effect of these treatments in clinical trails are rather controversial.The purpose of this paper is to conduct a meta-analysis on the clinical effect and related complications of SBRT and RFA for HCC.Methods A computerized retrieval of academic papers concerning the treatment effect of SBRT and RFA for HCC from the databases of PubMed,Embase,Cochrane Library,Scopus,Web of Science,CBM,CNKI,Wanfang database,VIP was conducted.The retrieval time period was from the establishment of the database to June 2022.Stata14.0 software was used to make meta-analysis.Results A total of 14 retrospective studies including 6 806 patients were included in this analysis.The results of combined hazard ratio(HR)based on overall survival(OS)showed that the OS rate of SBRT was lower than that of RFA(HR=1.25,95%CI=1.10-1.43,12=0%,P=0.000 9),while the results of combined HR of local control(LC)rate indicated that SBRT had a better therapeutic effect(HR=0.61,95%CI=0.47-0.78,I2=0%,P=0.000 1).Subgroup analysis revealed that the combined HR of LC rate favored the performance of SBRT for patients with tumor diameter larger than 2 cm(HR=2.64,95%CI=1.56-4.48,I=0%,P=0.000 3).No statistically significant difference in the incidence of late serious adverse reactions existed between SBRTgroup and RFA group(OR=1.01,95%CI=0.59-1.73,I2=30%,P=0.97).Conclusion SBRT is superior to RFA in controlling local HCC lesions,especially in patients whose tumor diameter is larger than 2 cm,although it does not show certain advantages in the survival benefit.(J Intervent Radiol,2023,32:1233-1241)
