To induce Crohn disease in rats by intraluminal instillations of different concentrations of 2,4,6-trinitrobenzenesulfonic acid (TNBS) and ethanol.

OBJECTIVETo observe effects of treatment from the lung and treatment from the intestine on the level of vasoactive intestinal peptide (VIP) in the lung and intestine of ulcerative colitis (UC) rats.

METHODSThe UC rat model was established in 52 rats by using rabbit intestine mucosa tissue allergen combined TNBS-ethanol model (with the model successful rate of 78.0%). Eight rats randomly selected from 40 successfully modeled rats and 8 of 16 rats from the normal group were recruited as the model group and the normal control group before intervention (at week 0). The rest 32 successfully modeled rats were randomly divided into the model group, the Western medicine treatment group (salazosulfapyridine), the treatment from lung group (Huangqi Jiegeng Decoction), and the treatment from intestine group (Huangqi Huanglian Decoction), 8 in each group. Rats in each treatment group were administered with corresponding medication 8 times the dose of a 60 kg adult human. Another 8 normal rats were recruited as the normal group. Equal volume of pure water was given to rats in the model group and the normal group by gastrog avage, once per day. Contents of VIP in the lung tissue and the intestinal tissue were detected at week 0 and 4 after 4-week consecutive intervention. Pathomorphological changes of the lung tissue and the colon tissue were observed under light microscope.

RESULTSCompared with the normal control group at week 0, evenly distributed diffuse inflammation could be seen in the pulmonary interstitial tissue; the bronchial wall was thickened; a huge amount of infiltration surrounded bronchi and blood vessels; a large area of necrosis of intestinal mucosa and inflammatory cell infiltration could also be seen in the model group. Pathological injuries of the lung and the colon were more alleviated in each treatment group than in the model group at the same time point. Compared with the normal control group at the same time point, VIP contents in the lung tissue significantly decreased in the model group at the end of week 4 (P<0.05); VIP contents in the colon tissue significantly increased in the model group at the end of week 0 and 4 (P <0.05). Compared with the model group, VIP contents in the lung tissue significantly increased in the Western medicine treatment group and the treatment from lung group at the end of week 4 (P<0.01); VIP contents in the colon tissue significantly decreased in the treatment from lung group and the treatment from intestine group (P<0.05, P<0.01).

CONCLUSIONTreatment from the lung and treatment from the intestine showed predominant advantage in improving local inflammation of the lung and the intestinal tract, alleviating pathological injuries, promoting repair of injuries through regulating VIP contents in the lung tissue and the colon tissue.

Objective:To evaluate the clinical value of percutaneous transhepatic cholangial drainage (PTCD) and percutaneous transhepatic cholangial stent(PTCS)implantation therapy for malignant biliary obstruction in the elderly patients.Methods:Fifty three patients over 60 years-old were treated with PTCS implantation (n=35),PTCD for internal-external drainage(n=11),or single external drainage(n=7). The imaging examination was performed for all the patients one week after surgery. The serum levels of total bilirubin (TBIL) and alanine aminotransferase (ALT) were detected before and after surgery.Rusults:Metallic stents were successfully implanted in 32 patients during the surgery, and 3 patients were implanted 5 to 7 days later after PTCS. Both total serum levels of TBIL and ALT were significantly decreased at one week after surgery (P<0.05). The mean survival periods were 11.5 months for stent implantation patients and 5.5 months for PTCD patients. Conclusion:PTCD and PTCS are easy to perform and safe and effective in the treatment of malignant biliary obstruction of elderly patients.

Objective:To evaluate the outcome and prognostic factors of conventional radiotherapy followed by intensity-modulated radiation therapy (IMRT) as a boost combined with chemotherapy in the treatment of high-grade gliomas (HGG). Methods:From Nov. 2004 to Nov. 2006, 112 HGG patients were treated with conventional radiotherapy followed by IMRT as a boost combined with chemotherapy. The radiotherapy regimen included first-course conventional radiotherapy and latE-course IMRT as a boost with the total radiation dosage of 57.5- 62.5Gy (27-29 fractions in 37-45 days). All the patients received chemotherapy. Sixty-three patients received temozolomidE-based chemotherapy and 49 patients received semustine plus teniposide chemotherapy. The treatment reaction was recorded. The overall survival rate and local progression-free survival rate were calculated. The prognostic factors were analyzed by using multivariate COX regression model. Results:The acute treatment toxicity was the most at grade 1 to grade 2 and no grade 4 adverse reaction was observed. Three cases had late radiation-induced brain necrosis. The overall 1-, 2-, and 3-year survival rates were 78.9%, 54.7%, and 30.8%, respectively. Multivariate analysis revealed that tumor location (P=0.001) and KPS score (P=0.011) were independent prognostic factors. The 1-, 2-, 3-year local progression-free survival rates were 63.8%, 38.9%, and 10.5%, respectively. Multivariate analysis revealed that tumor location (P=0.001), KPS score (P=0.001), and histologic type (P=0.005) were independent prognostic factors. Multivariate analysis did not reveal the significant correlation of temozolomide chemotherapy with the prognosis of the patients. Conclusion:Postoperative conventional radiotherapy followed by IMRT as a boost combined with chemotherapy has better short-term efficacy in the treatment of HGG and the adverse reaction is tolerable. KPS score, tumor location, and histologic type are important prognostic factors. Temozolomide chemotherapy is not associated with the prognosis of patients.

Objective To investigate the development trend of drinking-water-borne endemic fluorosis in Jiangsu Province,and to provide the basis for further prevention and treatment of the disease.Methods In 2009,eight major counties were chosen,and in each county all diseased villages were classified into light,moderate and severe disease types according to water fluorine content based on historical data,and one village was chosen from each type.In monitoring villages with improved water,one source water and three tap water samples were collected,respectively.Five water samples were collected in water unimproved monitoring villages according to water well locations of the east,the west,the south,the north and the center.The fluorine content in water was determined according to the Standard Testing Methods for Drinking Water (GB/T 5750-2006).Children aged 8 to 12 were examined for dental fluorosis by Dean method.Residents over the age of 16 were examined for clinical osteofluorosis,and two monitoring counties were chosen,then one village was respectively chosen in each county,and clinically diagnosed patients with skeletal fluorosis were examined again by X-ray.Both clinical and X-ray diagnosis were on the basis of Diagnostic Criteria of Endemic Skeletal Fluorosis (WS 192-2008).Urine samples of 30 children aged 8 to 12 and of 20 adults over the age of 16 were randomly collected and urinary fluoride was determined by F-ion selective electrode method(WS/T 89-1996).Results Of all the 24 villages of 8 counties,20 villages were water improved,and water-improvedprojects ran normally in 18 villages,while scrapped in the rest 2 villages.One hundred and two samples were tested,and the mean of water fluoride in water-improved villages was 1.10 mg/L,while in water unimproved villages and villages with water improved projects scrapped was 1.90 mg/L.The prevalence of dental fluorosis was 42.51％(854/2009).The prevalence of clinical skeletal fluorosis was 23.23％ (2024/8713) and the X-ray detection rate was 32.00％ (24/75).Six hundred and sixty-four urine samples of children were determined,and geometric mean of urinary fluorine was 1.59 mg/L,while 370 adult urine samples were determined,and geometric mean of urinary fluorine was 2.20 mg/L.Conclusions Endemic fluorosis in Jiangsu Province has not been fully controlled and there are signs of recovery.We must pay attention to water improvement measures to reduce fluoride and the management and maintenance of water improvement projects,and further strengthen the prevention and control of endemic fluorosis.

Objective To evaluate the effect of health education on endemic fluorosis in Jiangsu province,and to provide reference data for further prevention and control of the disease.Methods In 2011,according to history prevalence of endemic fluorosis in Jiangsu province,a total of 10 countries were selected,and 3 townships were chosen in each county.Health educational activities were carried out in the classes of grade 4 - 6 in thecentral primary school.In the meantime,3 villages were chosen in each selected township where the health educational activities in the community were carried out.Before and after the health education activities,questionnaire surveys on knowledge of endemic fluorosis were conducted in each county.Thirty students in one classof the fifth grade in the central primary school were randomly selected,and 15 housewives near the central primaryschool were also randomly selected.Results After the health educational activities,the rates of knowledgeawareness in the students and the housewives were 95.90％ (2946/3072) and 92.85％ ( 1752/1887 ),respectively,and increased significantly compared with those before the intervention[71.53％(2015/2817),77.40％( 1384/1788 ) ],and the difference was statistically significant(x2 =657.337,174.894,all P ＜ 0.01 ).Before the health educational activities,the rates of knowledge awareness in the students were lower than those in the housewives,and the difference was statistically significant (x2 =6.120,P ＜ 0.05 ).After the health educational activities,the rates of knowledge awareness in the students were higher than those in the housewives,and the difference was statistically significant(x2 =21.847,P ＜ 0.01 ).ConclusionsThe rates of knowledge awareness in the students and the housewives are increased significantly after the health educational activities.The consciousness and activity of the target people to take part in preventing and controlling of the endemic fluorosis have been enhanced greatly.The good behaviors in the target people are gradually formed,the desired effect is achieved.

Objective To investigate the state of endemic fluorosis, running status of water improvement project to reduce fluoride in Jiangsu province, and to provide a scientific basis for prevention and control of endemic fluorosis. Methods In 2008, in the ten key counties of endemic fluorosis (zone), in Xuzhou,Lianyungang and Suqian, a stratified sampling method was employed to select 40 diseased villages according to their past water fluoride survey data. All children aged 8 to 12 were examined dental fluorosis, and all adults over 16 years were examined clinical skeletal fluorosis. Thirty per cent of the 40 diseased villages were selected, and 20 adults over the age of 16 in each selected village were examined by X-ray, respectively;50% of the 40 diseased villages were selected, and 30 any time urine samples of children aged 8 to 12 in each diseased village were tested urine fluoride. In each city, select a county, the status of water improvement project to reduce fluoride, water supply capacity and coverage in the county were investigated. Results A total of 3560 children aged 8 to 12 were examined, the detection rate of dental fluorosis was 38.51% (1371/3560), tooth defect rate was 5.34% (190/3560), and dental fluorosis index was 0.8. Seven hundred and eight urine samples were tested, the median urinary fluoride was 1.47 mg/L and the range was 0.08 ~ 10.08 mg/L. Clinical detection of skeletal fluorosis was 21.3% among adults over the age of 16, and X-ray detection rate of skeletal fluorosis was 39.2% (123/314).Investigated a total of 248 facilities of centralized water improvement projects, no funds to run or damaged 49, the water fluoride > 1.0 mg/L was 18. Conclusions Endemic fluorosis in Northern Jiangsu province has not been controlled completely, but has a rising trend, we should further strengthen the supervision of water fluoride reduction.
