Objective To investigate the relationship between that vascular endothelial growth factor (VEGF) expression and microvessel density (MVD) distribution were in the small intestine mucous membrane and that urea and creatinine were eliminated from intestine inrenal failure rat used Shenfushu and atropine treatment.Methods Sprague-Dawely (SD) rats with 5/6 kidney resection were randomly divided into Shenfushu treatment group,Shenfushu + atropine treatment group,pathological control group,and sham operation group for the normal controls.Treatment groups were drenched for eight weeks.Before and after treatment,the concentration of blood urea nitrogen (BUN),serum creatinine (Scr),the fecal urea and fecal creatinine were detected; the expression levels of VEGF and MVD in the small intestinal were detected with small intestinal biopsy immunohistochemical method.The relationship between that expression of VEGF and MVD,and that concentration of BUN,Scr,the fecal urea,and fecal creatinine was analyzed.Results VEGF in the Shenfushu treatment group,Shenfushu + atropine treatment group,and pathological control group was (20.72 ± 1.8) pu,(24.32 ± 1.54) pu,and (28.69 ± 1.82) pu,respectively; MVD was (274.27 ± 10.62)/mm2,(332.71 ± 10.96)/mm2,(436.42 ± 13.70)/mm2,respectively.Expressions of small intestinal VEGF and MVD in two treatment groups were increased significantly than the control group.The concentrations of BUN and Scr were significantly decreased with a negative correlation with the expressions of VEGF and MVD.The concentrations of fecal urea nitrogen and fecal creatinine were significantly increased with a positive correlation with the expressions of VEGF and MVD (P ＜0.05).The concentrations of BUN and serum Cr in the Shenfushu + atropine group were significantly changed more than Shenfushu group (P ＜ 0.05).Conclusions Shenshuaikang and atropine could enhance the expression of VEGF in the small intestinal mucosa,increase microvascular density,promote the elimination of urea nitrogen and creatinine from the intestinal tract to decrease the concentrations of BUN and Scr.Those effects were more obvious with two drugs in combination.

Objective To review the research advancement of multimodal therapy for advanced gastric carcinoma.Methods The literatures on multimodal therapy for advanced gastric carcinoma in recent years were collected and reviewed.Results The multimodal therapy,such as preoperative chemotherapy,preoperative adjuvant chemoradiotherapy,preoperative interventional chemoradiotherapy for advanced gastric carcinoma was effective because it could increase the rate of R0 resection for the patients with advanced gastric carcinoma.And it can decrease the mortality rate after operation,extend the overall survival time and improve patients' life quality.Conclusion Multimodal therapy is a promising method for the treatment of advanced gastric carcinoma and it should be further developed.

Objective To explore the ability of intestinal bacteria making use of creatinine in the patients with uremia and healthy subjects. Methods Creatinine, which was energy source only,and tetrazolium violet as indicator were added into intestinal bacteria of the patients with uremia and healthy subjects(n=10). It was positive that solution showed violet. Intestinal bacteria were added in Nutrient Broth medium with creatinine. The concentration of creatinine was measured before and after incubation. Results The solution of intestinal bacteria of the patients with uremia showed violet. The solution of intestinal bacteria of healthy subjects showed bright violet.The concentration of creatinine decreased after incubation in both groups. Conclusions The intestinal bacteria of uremic patients and healthy subjects had the ability to make use of creatinine. The former was stronger than the latter.

Objective To investigate the relationship between the HIF-1? expression and tumor biological characteristics in non small cell lung cancer(NSCLC). Methods The expression of HIF-1? in NSCLC tissues was evaluated by immunohistochemical method. Results The positive rate of HIF-1? expression in NSCLC was 71.11%, and significantly higher than that in normal lung tissues(P

Objective To investigate the expressions of Cycloxygenase-2(COX-2),vascular endothelial growth factor(VEGF) in non-small cell lung cancer(NSCLC) to explore the relationships between them and the tumor biological characteristics,tumor angiogenesis in NSCLC.Methods The expressions of COX-2,VEGF and the microvessel density(MVD) were detected by immunohistochemical staining.Results The positive rates of COX-2 and VEGF expression in NSCLC tissue were 55.5% and 66.7% respectively,with significantly higher than those of normal lung tissue(all P

Objective To improve the detection of G6PD heterozygotes in female patients by the optimum experimental factors of G6PD/6PGD specific value assay.Methods (1)Identifying the mutations of G6PD gene with the use of amplified refractory mutation system (ARMS).(2)Measuring the G6PD/6PGD specific value.Results According to the data analysed by statistics and ROC curve, the optimum experimental factors included that the incubation temperature was 37℃,the substrate concentrations were 0.78 mmol/L G6PNa2 and 0.195mmol/L NADP+, the reaction time was 10min.Conclusion The optimum experimental factors of G6PD/6PGD specific value assay may be used to improve the detection rate of G6PD heterozygotes in female patients.

Objective: To explore the effect of lavage with artiifcial cerebrospinal lfuid on neural cell apoptosis and the extracellular regulated kinase (ERK) pathway atfer traumatic brain injury. Methods: A total of 192 SD rats were randomly divided into a sham group, a traumatic brain injury model group, a local artiifcial cerebrospinal lfuid group, and a local saline group. Each group was divided into 4 sub-groups by the sacriifced time at 6 h, 12 h, 1 d and 3 d atfer the operation. hTe phosphorylation of extracellular regulated kinase 2 (P-ERK2), TNF-α and cellular apoptosis were examined. Results: hTe levels of P-ERK2 protein and TNF-α protein, as well as the number of apoptotic cellsat each time point in the local artiifcial cerebrospinal lfuid group were lower than those in the model group or in the saline group (P<0.05). Conclusion: Lavage with artificial cerebrospinal fluid can reduce apoptosis of neural cells after brain injury through the ERK pathway.

Objective To investigate the regulation effect of interleukin-1? (IL-1?) on the expression of VEGF in A549 cells. Methods A549 cells were incubated with IL-1? in the presence or absence of Celecoxib. After incubation, cells were harvested to detect VEGF mRNA by reverse transcription-polymerase chain reaction (RT-PCR), and the supernatant was collected to determine the concentration of VEGF protein by enzyme-linked immunosorbent assay (ELISA). Results After treatment with IL-1?, the expression of VEGF mRNA and protein in A549 cells were significantly higher than that in the control group(P

Objective To evaluate the clinical efficacy and surgical method in radical debridement and spinal fusion with internal fixation in surgical management of cervical vertebra tuberculosis.Methods Twenty-one patients of cervical vertebra tuberculosis were included,mean age of 31 years,including 2 cases at C_(1-2),3 at C_(2-3),9 at C_(4-5),3 at C_(5-6),3 at C_(6-7),1 at C_7T_1.After all patients underwent radical debridement of focuses,15 cases were grafted with iliac bone and 6 with titanium mesh,19 cases were fixed with plate,1 case with Apofix,1 case with Occipital-cervical fusion.The external fixation was needed for 3 months after surgery.Results The follow-up lasted for 21 months.One case grafted with titanium mesh failed,but other patients achieved satisfactory results of successful interbody fusion within 3 to 6 months.The kyphosis deformity was corrected to normal condition without associated complications.The neural symptoms were improved.All patients had no recurrence of tuberculosis.There were no plates and screws broken.Conclusion It is safe and effective to treat cervical vertebra tuberculosis by anterior radical debridement and primary autograft by internal fixation,with high correction rate of local kyphosis deformity,high fusion,and low complication rate.
