BACKGROUND:It has been demonstrated that there are different expressions of fatty acid binding proteins (FABPs) in most malignant tumors such as breast cancer, prostate cancer, liver cancer, lung carcinoma and bladder carcinoma;therefore, FABPs are closely related to the occurrence, metastasis, invasion and drug resistance of malignant tumors. OBJECTIVE:To investigate the effects of fatty acid binding protein-5 (FABP-5) silencing on the proliferation, invasion and apoptosis of U251 cel s (human glioma cel s). METHODS:siRNA molecules targeting the mRNA of FABP-5 was designed and chenical y synthesized, which was transiently transfected into U251 cel s. U251 cel s were divided into three groups:Lv-shRNA-FABP-5 was added into FABP-5-shRNA group, LV-shRNA-NC added into negative control group, and blank control group underwent normal culture. mRNA and protein expressions of FABP-5 were detected by RT-PCR and western blot assay, respectively. The cel proliferation in vitro was determined by cel counting kit-8 assay, the cel cycle, apoptosis and expressions of CD44+and CD133+were detected by flow cytometry, and the apoptosis was observed using TUNEL staining. RESULTS AND COUNCLUSION:mRNA and protein expressions of FABP-5 in the FABP-5-shRNA group were significantly lower than those in the negative control and blank control groups. Compared with the negative control and blank control groups, the cel growth rate was significantly decreased, the cel cycle arrested in the G0/G1 phase, and the cel number in the S phase was decreased, and moreover, the proportion of CD44+/CD133+expression was significantly decreased in the FABP-5-shRNA group (P<0.05). Besides, compared with the negative control and blank control groups, the apoptosis rate was significantly increased, and the cel proliferation and invasiveness were significantly decreased in the FABP-5-shRNA group (P<0.05). In conclusion, it is possible that FABP-5 directly or indirectly regulates the cel cycle and apoptosis of glioma cel s, and its expression changes share a close relationship with the invasiveness of tumor cel s.

0.05), respectively. CONCLUSION: Scheme B is the preferable one in cost-effectiveness,however,Scheme C is the best one by comprehensive comparison.

Objective To study the clinical effect of microsurgical surgery for the treatment of intracranial aneurysms in the acute phase. Methods 88 patients with intracranial aneurysm who were treated with the microscopic surgery in our hospital were selected as the research object. The prognosis was evaluated by Glasgow scale ( GOS) ,and the mortality rate during the follow-up period and postoperative complications were observed. Results All the patients received surgery success. The operation time was (60. 5 ± 20. 3) min,and the intraop-erative blood loss was (45. 2 ± 21. 5) mL. 12 months after operation,according to the GOS score of daily living ability,42 patients were of good prognosis and the other 46 cases were of poor prognosis. The good prognosis rate was 47. 7% and it is significantly higher than that of 3 months and 6 months after surgery. The difference was statistically significant (P<0. 05). There were 4 cases died among the 88 patients with a mortality of 4. 5%. Conclusion Using microsurgical treatment to treat intracranial aneurysms can receive good prognosis and low mortality rate. Complications were significantly improved after symptomatic treatment.

Based on thorough analysis of the present healthcare big data,and present problems found in precision medicine,the paper proposed the implementation approach of precision medicine driven by healthcare big data.Citing the practice of the hospital as an example,the authors centered on clinical data to build a precision medicine knowledge system,and leveraged in-depth data mining to develop integrated analysis technology for precision medicine.These efforts aim at application development of precision medicine series upon a panoramic medicine knowledge display,so as to enhance medical quality and diagnosis efficiency and translated use of healthcare big data in precision medicine.

ObjectiveTo investigate the expression of CXCR4 and CD133mRNA in primary lesion of primary gastric adenocarcinoma and the relation with clinicopathological features,and to explore the correlation of CXCR4 and CD133.MethodsThe primary lesion of primary gastric adenocarcinoma and normal tissues adjacent to gastric cancer were obtained from 50 patients.The diction of CXCR4 and CD133 protein expression was detected by the immunohistochemical staining,and the relative gray scale values of CXCR4 and CD133mRNA by semi-quantitative RT-PCR (Fisher' s exact probability method).Their relationship with clinicopathological features was also investigated ( Spearman relation analysis).ResultsThe positive rates of CXCR4 and CD133 protein in gastric cancers were 76.0％ and 66.0％ respectively,which were significantly higher than that in normal tissues adjacent to gastric cancer ( 16.0％ and 10％ ; P =0.000,P =0.000).The increment of relative gray scale values of CXCR4mRNA was associated with the larger tumor diameter,the later TNM stage and the occurrence of lymphatic metastasis( P ＜ 0.05 ).And the larger diameter of tumor,the later TNM stage were associated with the higher relative gray scale values of CD133mRNA (P ＜0.05).The levels of the relative gray scale values of CXCR4 mRNA and CD133mRNA were positively related(r =0.453,P ＜ 0.01 ).ConclusionsThe higher expression of CXCR4 and CD133mRNA correlateswith tumour diameter,TNM stage and lymphatic vessel invasion. The relative gray scale values of CD133mRNA increase with the increment of the relative gray scale values of CXCR4.

Objective To investigate the effects of keratinocyte growth factor (KGF) and KGF receptor (KGFR) antisense oligonucleotide (ASODN) on cell cycle and apoptosis of HaCat cells. Methods HaCaT cell, an immortalized keratinocyte cell strain, was cultured in vitro. Flow cytometry was used to measure the cell cycle and apoptosis mediated by KGF and ASODN. Results The rates of S phase and apoptosis in the group treated with KGF increased significantly than those in the control group (both P

OBJECTIVETo investigate the relationship between the endogenous vascular endothelial growth factor (VEGF) gene expression in diabetics' calf ischemic skeletal muscle and the pathogeny of diabetic foot.

METHODSTwenty-four patients (33 limbs) were divided into 3 groups: diabetes mellitus (DM) without lower extremity ischemia (n = 5) (10 limbs); arteriosclerosis obliterans (ASO) without diabetes mellitus (n = 10) (13 limbs); diabetic lower limb arteriosclerosis obliterans (DLASO) (n = 9) (10 limbs). Control group consisted of normal volunteers (NOR) (n = 5) (10 limbs). The calf skeletal muscle tissue was obtained through muscle biopsy. RT-PCR was applied to determine the expression of hVEGF165mRNA.

RESULTSThere was no expression in the calf skeletal muscle tissue of normal volunteers and DM. The calf skeletal muscle tissue in DLASO had the expression of hVEGF165mRNA (0.021 +/- 0.013) micro g, but obviously lower than ASO (0.133 +/- 0.024) micro g, (t = 13.32, P < 0.01).

CONCLUSIONSThe endogenous VEGF gene expression in ischemic lower extremity of DLASO is obviously lower than that of ASO. It is the important endogenic cause of the genesis and development of diabetic foot ulcer.

Objective To evaluate the curative effect of polyscope modular flexible ureteroscope combined with Holmium laser lithotrip-sy in the treatment of renal calculi. Methods 53 patients with renal calculi were performed CTU to detect the position of renal calculi before operation. The patients were treated with polyscope modular flexible ureteroscope combined with Holmium laser, and the double J tube were routinely indwelled 4 to 12 weeks after surgery. Results All the 52 patients has successfully completed the operation in the frist stage. The mean operative time was about 38 minutes. 6 patients were treated with flexible ureteroscope for second stage operation. One week after oper-ation, the review showed that there were residual calculi existed in 24 cases and there were 56 cases of post-operative infection, including 17 cases of sepsis or sepsis shock. Conclusion Polyscope modular flexible ureteroscope can be used for all kinds of kidney stones surgery and is characterized by safety and mild tissue injury. But we should pay more attention to the post-operative infection especially urosepsis.
