Objective To evaluate the long-term therapeutic efficacy of subtotal colectomy,ascending colon-rectum anastomosis, pelvic floor hernia repair, functional rectal suspension, and uterine suspension surgery for slow transit constipation with pelvic floor hernia and rectal mucosal prolapse.Methods From June 2007 to May 2008, 35 patients with intractable constipation caused by slow colonic transit combined with pelvic floor hernia and rectal mucosal prolapse underwent subtotal colectomy and ascending colon-rectum anastomosis, pelvic floor hernia repair, functional rectal suspension, and uterine suspension surgery. Postoperative defecation, complications, quality of life, and degree of satisfaction were followed-up. Results The average follow-up period was two years. At one month after the operation, the average defecation frequency was five times (2 -8 times) a day, with a semi-liquid stool consistency; After two years the frequency was twice ( 1 -3 times) a day, with solid stool consistency. Of the 35 patients, 19 were satisfied with the surgical efficacy, and 16 were very satisfied. All the patients' quality of life improved significantly. Conclusions For patients suffering from slow transit constipation with pelvic floor hernia and rectal mucosal prolapse subtotal colectomy, ascending colon-rectum anastomosis, pelvic floor hernia repair,functional rectal suspension, and uterine suspension surgery has satisfactory results.

Objective To explore the changes of genes associated with the nuclear factor of kappa B(NF-?B) signaling pathway in neonatal rats with early hypoxic-ischemic reperfusion brain damage(HIRBD).Methods Twenty-four SD rats at age of 7 days,with male to female of 1212,were randomized into normal control group(group A,n=8),hypoxic-ischemia reperfusion for 2 h(group B,n=8) and hypoxic-ischemia reperfusion for 4 h(group C,n=8).The tissues of hippocampus were taken for complete RNA extraction.Gene chip inspection and biological signal analysis technique were used to detect the expression of 113 involved signal molecules of NF-?B pathway.Results Compared with group A,the up-regulated expression was found in Chemokine(C-C motif) ligand 2,Dual specificity phosphatase 1,FBJ osteosarcoma oncogene(Fos) and Toll-like receptor 9.Whereas the expressions of Caspase-1,8,Mitogen-activated protein kinase kinase 6,Mitogen activated protein kinase 3 and Ras homolog gene family member a from Ras-gene famimly was found down-regulated in group B.The up-regulated expression was in Fos,IL-1? and Toll-like receptor 6,but that of down-regulation was found in Caspase-1,Extracellular matrix protein 1,Lysophosphatidic Acid G-protein-coupled receptor 2,Mucosa associated lymphoid tissue lymphoma translocation gene 1,Inhibitor of kappa B kinase epsilon and Ras homolog gene family member c.Conclusions At the early stage of HIRBD,the Toll-like receptors may induce NF-?B activation,leading to the coordinated induction of multiple genes,which is involved in inflammatory,apoptosis and cell proliferation.Genes induced by NF-?B are responsible for the physiopathological process of early brain damage in neonatal rats with HIRBD.

Objective To find out the situation of Kashin-Beck disease and it's dynamic changes in Yan'an city, and provide basis for decision-making on prevention and control of the disease. Methods In accordance with the national monitoring program on Kaschin-Beck disease, 21 villages were selected from 6counties in Yan'an, clinical and X-ray inspection of 7 to 13 year-old children were made according to historical illness information from 2006 to 2008. Clinical monitoring on Kashin-Beck disease was made in 2008 for people over 16 years old from 5 villages in 5 counties. Results One thousand and one hundred eighty children were found positive with the illness from 2006 to 2008, with 7 cases of grade Ⅰ , the detection rate was 0.59%(7/1180).One thousand and one hundred sixty-two people were taken X-ray photo on right hand, with no positive case found.In 2008, 1444 adults were taken clinical examination, the detection of grade Ⅰ and over were 160 cases, the detection rate was 11.08%(160/1444), mainly in the age of 36 years[93.75%(150/160)]. Conclusion KashinBeck disease in Yan'an city is in stable condition, but surveillance and preventing measures are stilled needed.

[Objective] To detect the expression of NAD(P)H oxidase (Nox) and the content of ROS in different malignant gliomas,and explore the influence of Nox and intracellular ROS levels in the survival,proliferation,and malignant phenotype of gliomas.[Methods]Thirty human glioma specimens (10 with grade Ⅰ and I1,10 with grade II and 10 with grade IV),performed resection in our hospital from August 2007 to August 2010,were collected in our study;another 10 normal brain tissues were collected as controls.Real time PCR was used to detect the mRNA expressions of Nox(1-5);ROS level was detected by flow cytometry and Nox4 protein level was detected by immunofluorescence and Western blotting.[Results] The Noxl-5 mRNA and protein levels and ROS content were significantly different between each 2 groups (P＜0.05);Nox4 mRNA expression and ROS level significantly increased following the increment of malignancy degrees (controls＜low-grade gliomas＜grade III gliomas＜ grade IV gliomas,P＜0.05);the Nox protein expression was low in controls while that in gliomas was high,and the higher malignancy of the tumors,the higher expression levels of the tumors.[Conclusion] Nox expression and ROS content have significantly positive relations with the malignancy of the tumors,which indicates that Nox expression and ROS content might paly important roles in the occurrence of glioma and malignant proliferation.

Objective To investigate the distribution of water-borne fluoride and the current situation of endemic fluorosis in Yan'an city in 2006, and to evaluate the effect of water defluoridation project by improving driking water quality. Method In 2006 in Yan'an city, 5 samples from water source were collected in each selected village that was chosen according to 5 directions of East, West, South, North, and Central. Meanwhile, 1 sample from water source, 1 sample from water processing factory and 2 tap water samples were collected from each water defluoridation project. Water fluoride was determined by spectrophotometric method, teeth and skeletal fluorosis examination were performed by Dean method and "national criteria of endemic skeletal fluorosis diagnosis of China" in children aged 8-12 year and adults, respectively if water fluoride level > 1.00 mg/L Results Of 726 water samples from 293 villages tested, samples from 25 villages had higher fluoride( > 1.00 mg/L), and these villages covered a population of 11 610 people and most of these people were in Wuqi and Yanchuan counties. Water fluoride ranged from 0.10 mg/L to 3.50 mg/L, with median being 0.59 mg/L. Of 100 water samples from 25 water defluoridation projects, only 1 sample exceeded the national criteria in Yanchuan, and Wuqi counties, respectively,with fluoride level being 1.85 mg/L and 1.60 mg/L, respectively, and population exposed was 3083 and 708, respectively, with water fluoride ranged 0.30 - 2.00 mg/L In the examination of 1281 children aged 8 - 12, we detected 238 cases of dental fluorosis, and the detection rate reached 18.58%; 13 900 adults were checked, and 375 cases were confirmed of skeletal fluorosis, a detection rate reached 2.70%. Conclusions Yan'an has a wide range of water with high fluoride and severe fluorosis people. The water defluoridation projects need to be further improved. The task of prevention of endemic fluorosis is still arduous, and we should speed up the implementation of comprehensive water defluoridation measures.

OBJECTIVETo investigation the shielding property to (125)I of several different prosthetic materials used in clinical when prostheses are used as carriers of (125)I seed in tumor treatment.

METHODS(125)I seeds were taken as the radiation sources to establish a model in vitro and the radiation doses were measured by thermoluminescent dosemeters (TLD). The shielding property of titanium plate, cochrome plate, and poly methyl methacrylate (PMMA) plate were detected, calculated and compared with that of plumbum plate in the control group.

RESULTSThe radiation doses of the radiation source at 10 mm distance through the following materials were measured, and the results are 2.805 mGy (0.09 mm thick titanium plate), 1.082 mGy (0.48 thick titanium plate), 0.390 mGy (0.41 mm thick cochrome plate), and 0.261 mGy (0.67 mm's cochrome plate), and 2.885 mGy (1.685 mm thick PMMA plate).

CONCLUSIONSThe shield property of cochrome is optimal. The poly methyl methacrylate behaves to some extend as a shield to the (125)I seed which can shield the radiation as the effects of plumbum when adopted together with the 0.557 mm's (or more) titanium plate.
