Objective To evaluate the feasibility of active breathing control (ABC) in conformal radiotherapy (CRT) for patients with non-small cell lung cancer (NSCLC). Methods From Feb 2005 to Mar 2008, 29 patients with inoperable NSCLC (stage Ⅱ-Ⅳ) were evaluated. For each patient, two series of CT scans were obtained with free breathing (FB) and ABC system during simulation, respectively. Then two confonnal radiotherapy (CRT) plans were finished based on the two sets of reconstructed images. The pattern of post-inspiratory breath-hold was triggered at 80% of the peak of inspiration curve. The margin of clinical target volume (CTV) to planning target volume (PTV) was 0. 6 cm for lesions of the superior lobe, and 1.0 cm for the lesions of middle and inferior lobes. Three to five coplanar fields were performed in conformal radiotherapy. The gross tumor volume (GTV), CTV, PTV, volume of the bilateral lungs (Volume_(lung)), V_(20) and mean lung dose (MLD) of two plans were evaluated by dose-volume histogram (DVH). The World Health Organization criteria and National Cancer Institute Common Toxicity Criteria 3.0 (NCI-CTC3.0) scale were used to assess the immediate response and acute side-effect, respectively. Results Significant differences of GTV, CTV, FIN, Volum_(lung), V_(20) and MDL were observed between the two plans (36. 35 cm~3 vs. 31.40 cm~3, t = 9. 70, P <0. 001 ;82. 33 cm~3 vs. 70. 83 cm~3, t = 8. 19, P < 0. 001 ; 230. 73 cm~3 vs. 197.59 cm~3 ,t=5.72,P <0. 001 ;21.66% vs. 18. 76% ,t = 11.16,P <0. 001 ;1329. 07 Gy vs. 1143. 14 Gy, t = 13. 24, P < 0. 001). With ABC, all patients completed their treatment successfully except one patient for financial problems. The median radiation dose to the GTV was 64 Gy (60 -64 Gy). The overall immediate response rate was 64% (18/28). According to the NCI-CTC 3.0, grade 1 and 2 acute radiation-related toxicities occurred in 68% (19/28) and 18% (5/28) of patients for esophagitis, 82% (23/28) and 7% (2/28) for pneumonitis, respectively. Grade 1, 2 and 3 bone marrow suppression occurred in 57% (16/28), 25% (7/28) and 14% (4/28) of patients, respectively. Grade 1 and 2 acute cardiac injuries occurred in 86% (24/28) and 14% (4/28) of patients. Conclusions During CRT for patients with NSCLC, the use of ABC can decrease the radiation dose and acute complications of normal tissues.

In this study, OVA-induced asthma mice was taken as the model, and orally administered with different concentration of ethanol extracts of crude and processed Stemona tuberosa, in order to determine the cytokine level released from Th1 and Th2 in splenocytes. RT-PCR was carried out to determine the genetic expression of T-bet/GATA-3 in lung, and compare the differentiation between ethanol extracts of crude and processed S. tuberosa in therapeutic effect on asthma in mice. According to the results, compared with the crude samples, processed samples significantly increased the levels of inflammatory factor INF-gamma (P < 0.05) and decreased IL-5 (P < 0.05) in splenocytes. According to the RT-PCR results, the administration of processed samples could increase the ratio of T-bet/GATA-3 (P < 0.05). The experiment showed that ethanol extracts of both crude and processed S. tuberosa could treat asthma by regulating Th1/Th2 ratio, but processed samples showed more notable effect. This indicated that crude and processed S. tuberosa had significant pharmacological difference. Therefore, it was more rational to apply processed S. tuberosa in clinical treatment of asthma and chronic cough, which layed a foundation for further revealing the processing mechanism of S. tuberosa.

Objective To study the exocrine pancreatic function in critically ill children with septic shock,sepsis and hyperlactacidemia.Methods A total of 64 critical pediatric patients were admitted from Jan 2009 to Oct 2012,and clinical and laboratory findings including pancreatic function,and histopathological features and score after autopsy were reviewed.Results (1) Compared with non-septic shock children,the pancreatic pathology score and serum lipase in septic shock group were significantly higher and serum calcium was significantly reduced (P ＜0.05) ; (2) The pancreatic histopathology score was significantly increased in patients with elevated plasma lactate ≥2 times (P ＜0.05),but there were no significant differences in serum calcium and blood amylase and lipase between patients with elevated plasma lactate level and patients with normal plasma lactate level; (3) The concentrations of serum amylase,lipase and urinary amylase were significantly increased in patients with pancreatic histopathology score ＞4 points compared with score ≤4 points patients,but there were no significant differences in above three biomarkers between patients with score ≤3 points and patients with score ＞3 points.Conclusions The pancreas is vulnerable to damage easily occurred in septic shock children especially complicated with hyperlactacidemia.The pancreatic histopathology score ＞ 4 points can be as a sensitive and reliable indicator of pancreas damage.

Objective To evaluate the value of differential diagnosis on congenital biliary atresia(BA) and infantile hepatitis syndrome(IHS) by technetium-99m-diethyl-iminodiacetic acid(99Tcm-EHIDA)hepatobiliary scintigraphy with phenobarbitol sodium.Methods Fifty-eight infants with persistent jaundice were taken phenobarbitol sodium[5 mg/(kg?d)] ,bid ?7 d).Those who had not bowel and gallbladders radioactivity within 24 hours were diagnosed as the diagnostic criterion of BA.Those with bowel and gallbladders radioactivity within 24 hours were diagnosed as the diagnostic criterion of IHS,who then received 99Tcm-EHIDA hepatobiliary scintigraphy with single photon emission computed tomography(SPECT) instrument.The results of all children were analyzed and compared with pathology and clinical follow up results.Results 99Tcm-EHIDA hepatobiliary scintigraphy correctly diagnosed 24 infants with last diagnosis BA and 29 infants with last diagnosis IHS,5 neonates false positive in all 34 IHS patients.The sensitivity in the diagnosis of BA was 100%,the specificity and accuracy were 85.3% and 91.4%,restectively.The sensitivity was 85.3% in the diagnosis of IHS;the specificity and accuracy were 100% and 91.4%,respectively.Conclusions 99Tcm-EHIDA hepatobiliary scintigraphy with phenobarbitol sodium can accurately differentiate BA and HIS at early stage.

Objective To establish a specific fluorescence quantitative method for determining the mRNA expression of Toll-like receptor3(TLR3)in peripheral blood mononuclear cells(PBMCs).Methods Using the Beacon Designer 2.1 software,specific primers and Taqman-MGB probe were designed.The plasmid pMD18-T-TLR3 was constructed as calibrator and the amplified fragment was obtained by reverse- transcript-PCR(RT-PCR).RNA quantification based on cycle threshold values(Ct)was used to establish the standard curve.According to which,the TLR3 mRNA levels in 30 normal individuals,20 patients with primary biliary cirrhosis(PBC)and 20 ones with chronic liver cirrhosis induced by HBV were calculated automatically by software after the fluorescence of PCR product was detected continuously during amplification.Results The linear detection range of the assay for TLR3 gene and ?-actin was 10~2-10~8(r= -0.9974)and 10~3～10~8(r=-0.9984),respectively.The coefficient of variation of both intra-and inter- assay reproducibility for high concentration sample were 6.7% and 8.7%,respectively,and those for low concentration sample were 12.3% and 14.0%.The TLR3 mRNA expression level ranges from 3.46?10~2- 4.51?10~3 copies/?g RNA,4.92?10~2-1.42?10~4 copies/?g RNA and 2.58?10~2-7.17?10~3 copies/?g RNA for 30 healthy individuals,20 PBC patients and 20 ones with chronic liver cirrhosis induced by HBV, respectively.Conclusion We have successfully set up a FQ-RT-PCR method for detecting TLR3 mRNA, which may be used as an excellent tool for the clinic and basic study on the expression of TLR3 gene.
