After brief introduction of FISH (fluorescence in situ hybridization),it was discussed of the FISH's application status in research on biological nitrogen removal in recent years. Base on the FISH technology,Characterization of the community in biological reactor could be showed exactly,but more research should be carried out for the study on the effluence on microbial community composition,which was caused by changing operating parameter of biological reactors on the microbial community composition,such as SRT,DO and C/N ratio.The combination of FISH and other methods such as PCR-DGGE and 16S rRNA/rDNA will led to the identification of the microbial community which response for the nitrogen-removal in wastewater treatment plant.

OBJECTIVETo observe the intervention effect of Leihong Granule (LG) in in-stent restenosis (ISR) after endovascular therapy for lower extremity arterial occlusive diseases (LEAOD).

METHODSRecruited 80 LEAOD patients who successfully underwent endovascular therapy (balloon dilation and stent implantation) were randomly assigned to two groups, the control group and the LG group, 40 in each group. Patients in the control group received basic treatment, while those in the LG group additionally took LG for 3 months. Plasma levels of IL-10, IL-18, CRP, and the intima-media thickness (IMT) of lower extremity artery were observed in the two groups between and after treatment. The rate of stent patency, ABI, intermittent claudication, rest pain, and the incidence of amputation the two groups were recorded and observed in the two groups.

RESULTSIn the control group, serum levels of IL-10, IL-18, CRP, and IMT were significantly higher one month after surgery than before surgery (P < 0.05). There was no significant difference in serum levels of IL-10, IL-18, CRP, or IMT between the two groups before surgery (P > 0.05). These indices were obviously lower in the LG group than in the control group after surgery (P < 0.05). Compared with the control group, the incidence rates of intermittent claudication and the rest pain at 6 months and 12 months after surgery significantly decreased (P < 0.05). The stent patency rate at 6 months and 12 months after surgery, and ABI were significantly higher than those of the control group (P < 0.05). There was no statistical difference in the amputation rate between the two groups (P > 0.05).

CONCLUSIONLG might effectively improve ischemic symptoms of affected limbs possibly through lowering the ISR rate after endovascular therapy for LEAOD through preventing immunosuppressive actions.

OBJECTIVETo investigate the expression differences of minichromosome maintenance 2 (MCM2) mRNA and protein among colon adenocarcinoma, colon adenoma and normal mucosa, and among different clinicopathological types of adenomas.

METHODSFifty specimens, including 33 colonic adenomas, 12 colonic adenocarcinomas and 5 normal colonic mucosa were selected. Each specimen was divided into two parts, one for immunohistochemistry and the other for real-time RT-PCR. Expression differences of MCM2 mRNA among the colonic adenocarcinoma, adenoma and normal colonic mucosa were evaluated by REST-XL software.

RESULTSThe expression of MCM2 was observed in the basal third to half of the colonic crypts in normal mucosa, while throughout the epithelium in the colonic adenocarcinomas and adenomas. However, the expression of MCM2 mRNA in the adenocarcinomas was significantly higher than that in the adenomas(P=0.001). The MCM2 mRNA expression was elevated in the adenoma with villous type, in the conditions of high-grade dysplasia, larger size, sessile morphology and in patients of older ages, but the difference was not significant by REST-XL (P>0.05).

CONCLUSIONThe difference of MCM2 expression between the adenoma and the adenocarcinoma indicates its potential value in the early diagnosis of colonic cancer.

A total of 121 subjects comprising 40 normal subjects,58 patients with overweight or obesity and 23 patients with Cushing's syndrome were recruited in the study.The modified radioimmunoassay (RIA) for salivary cortisol test was established'and its normal range was determined.Then the diagnostic value of the salivary cortisol for the initial diagnosis of Cushing's syndrome was evaluated and single midnight salivary cortisol test demonstrated a sensitivity of 100.0% and specificity of 91.4 %.Salivary cortisol test can be recommended as a first-line diagnostic parameter for Cushing's syndrome.

Objective To evaluate the role of imaging diagnosis in surgical treatment of primary aldosteronism(PA). MethodsFrom Jan 1995 to Dec 2004,245 patients with PA were hospitalized in our hospital.Before the operations,all the patients underwent B-ultrasonography and CT scaning,240 received intravenous pyelography and 75 MRI.The preoperative imaging diagnosis were compared with the findings during the operations and postoperative pathologic results. Results Compared with the findings during the operations,the accuracy rates of localized diagnosis for PA with B-ultrasonography,CT scanning and MRI were 92.7%,98.2% and 90.4%,respectively.Compared with the postoperative pathologic results,the accuracy rates of qualitative diagnosis for aldosterone-producing adenoma(APA) with B-ultrasonography,CT scanning and MRI were 83.0%,90.7% and 72.2%,respectively. Conclusion The comprehensive imaging data are helpful in the localized diagnosis of PA.Correct preoperative qualitative diagnosis of APA is the key step for the surgical treatment for PA.

Objective To explore the feasibility of constructing tissue engineered porcine corneal stroma with skin fibroblasts in vivo.Methods Skin fibroblasts were isolated from embryonic porcine,cultured and expanded in vitro.Cells were labeled with green fluorescence protein(GFP) gene by retro-viral infection.Cells at passage 3 were seeded on polyglycolic acid(PGA) non-woven fibers to form a cell-scaffold complex.The complexes were then implanted into porcines' corneal stroma after culturing in vitro for 1 week.Engineered stroma was observed continuously and harvested after 8 weeks for gross and histological evaluation.PGA with corneal stromal cells was served as control. Results The engineered tissue in the stroma gradually became transparent over a period of 8 weeks,showing no difference with the control group.Histologically,the engineered stromal lamellar was relatively regular and similar to the control.The implanted cells were confirmed by GFP expression under fluorescent microscope.By transmission electron microscopy examination, no significant difference in the diameter of collagen fiber was observed between the engineered stroma and normal stroma. Conclusion Tissue engineered corneal stroma may be formed with skin fibroblasts in porcine corneal microenvironment.

AIM: To investigate the ocular complication after radiation therapy for nasopharyngeal carcinoma(NPC).METHODS: The authors performed a previous study on keratopathy in 213 NPC patients who received first stage radiation and had at least 10 months of follow-up. These patients were categorized into three groups depending on NPC clinic stages. Rates and proportions of keratopathy occurring in these groups were compared and analyzed with Chi-square Test and Spearman rank correlation coefficient.RESULTS: Radiation keratopathy developed in 19 patients, about 8.9% (19/213). The latency value was 3 to 30days. The effect of NPC clinic stages and radiation did on the development of keratopathy was not statistically significant (P＞0.05).CONCLUSION: The NPC clinic stages and radiation doses plays few effects on the development of keratopathy. It may play a key role that corneal nerves damage induced ocular surface diseases. It can not be excluded that individuals have different sensitivities to radiation.
