Objective To study the therapeutic and protective effect of low tidal volume(LTV) ventilation in children with acute respiratory failure.Methods Forty-eight patients with respiratory failure were enrolled in our study.The patients were suffered from severe infection,trauma or after major operation.Besides general treatments,they were all given ventilation with LTV.Blood gas,ventilation parameters and complications related to ventilation were also measured.Results No significant difference was found between the patients with high tidal volume(HTV) and those with LTV in the results of improving respiratory acidosis.But the incidence of(ventilated-)induced lung injury(VILI) was lower in LTV patients.Conclusion LTV ventilation is preferable for children with acute respiratory failure and beneficial for alleviation of VILI.

Objective An investigation was conducted to assess the chemopreventive effects of celecoxib, a selective cyclooxygenase(COX)-2 inhibitor, on a rat colon carcinogenesis model induced by dimethylhydrazine (DMH). The results were compared with those of sulindac. Methods Thirty-two 8-week-old female Sprague-Dawley rats were randomly divided into four groups (n=8 each):Group A rats were treated with DMH(120 mg/kg wt, single subcutaneous injection) alone and group B rats were treated with saline alone. Group C rats were pre-treated with sulindac (320 mg/kg feedstuff) and group D rats pre-treated with celecoxib (1500 mg/kg feedstuff) for 7 days before DMH initiation. The animals were killed at the end of the experiment (week 5) and the aberrant crypt foci(ACF) and aberrant crypt(AC) of the colonic mucosa were assessed after being stained with methylene blue. Results In group A(DMH only), the average numbers of ACF and AC were 182.4?93.43 and 262.8?197.8 respectively. In group B (saline group) rats, no ACF was found. In group C (sulindac group) rats, the average numbers of ACF and AC were 91.25?48.98 and 139.60?68.52 respectively, both of them were decreased significantly as compared with those in Group A (P

Objective To investigate the anti-HBV molecular mechanisms of liver targeting interferon ( IFN-CSP ) in Balb/c-HBV transgenic mice.Methods Balb/c-HBV transgenic mice were randomly divided into 3 groups.Control group (treated with physiological saline), IFN α2b group (treated with 103 U/g IFN α2b), IFN-CSP group (treated with 102 U/g IFN-CSP).Another group of the non-transgenic mice were used as the Normal group.Each mouse was intramuscular injected with 50 μL dose once a day for 4 weeks.Total RNA of mice liver were extracted, and STAT1, STAT2, IRF-9, OAS1 gene expression of JAK-STAT signaling pathway were analyzed by real-time PCR.Results IFN α2b and IFN-CSP can significantly up regulate the expression of STAT1, STAT2, IRF-9, OAS1 gene of JAK-STAT signaling pathway (P<0.01).The induce effects of IFN-CSP on STAT1, STAT2, IRF-9, OAS1 were significantly better than that of IFN α2b (P<0.05).Conclusion The anti-HBV molecular mechanisms of liver targeting interferon (IFN-CSP) in Balb/c-HBV transgenic mice maybe related to regulate the expression of STAT1, STAT2, IRF-9, OAS1 gene of JAK-STAT signaling pathway.These results will lay a basis for the application of recombinant liver-targeting interferon.

Objective To analyze the long-term results of fractionated stereotactie radiotherapy(FSRT)for the local residual lesion after the first course of radiotherapy for nasopharyngeal carcinoma.Methods From July 1997 to July 2002,46 patients were treated with FSRT.According to the 1992 Fuzhou staging system,the number of patients was 1,6,30 and 9 with stage Ⅰ,Ⅱ,Ⅲ and Ⅳ disease,respectirely;3,11,27 and 5 with T1,T2,T3 and T4 tumor,respectively;14,16,12 and 4 with N0,N1,N2and N3 disease.Radiotherapy was delivered to tumors with the total of dose 68-70 Gy in 7-8w.Chemotherapy(2 cycles of PVF or POF)was given to the patients with stage Ⅲ and Ⅳ a disease.FSRT was given to the residual disease with the total dose of 18-24 Gy in 3 fractions with an interval of 3-7 days.The reference dose line was 70%-90%.Resuits CR and PR rates in this group were 61%and 39%,respectively.The overall survival rates of each year from 1- to 5-year were 100%,87%,83%,78%and 76%.The 1-,3- and 5-year disease-free survival rates were 100%,93%and 89%;The distant metastasis-free survival rates were 100%,85%and 79%;The local-regional control survival rates were 100%,94%and 91%.Seventeen patients who died during the follow-up period were 1 for local cervical lymph node recurrence,2 for fatal nasopharyngeal hemorrhage,4 for local nasopharynx recurrence,and 10 for distance metastases. Conclusions Fraetionated stereotactic radiotherapy is safe and effective for the patients with residual lesion of nasopharyngeal carcinoma at the primary site after radiotherapy.The optimized fractionation and total dose requires the further investigation.

Objective To analyze endoscopic histological characters and establish diagnostic standards of colorectal polyps with confocal laser endomicroscopy (CLE) examination and to explore the diagnostic value of the CLE in adenomatous polyps and non-adenomatous polyps. Methods From June to December in 2009, 90 patients were recruited in this study, which included 40 pathologically confirmed colorectal polyps patients (total 48 colon and rectal polyps) and 50 patients for prospective study (total 106 colon rectal polyps). At same time 10 spots of normal mucosa was taken for comparison. Firstly the CLE images of 48 pathologically confirmed colorectal polyps (22 adenomatous polyps and 26 non-adenomatous polyps) were analyzed, and the diagnosis criteria for distinguishing adenomatous polyps and non-adenomatous polyps was established with CLE. Then according to the criteria, 106 colorectal polyps underwent prospective diagnosis with CLE. Finally, the CLE diagnosis result was compared with pathologically result to evaluate the diagnosis efficiency of CLE. Results In the 48 colorectal polyps of 40 pathologically confirmed colorectal polyps patients, there were 22 adenomatous polyps and 26 non-adenomatous polyps. The sensitivity, specificity and accuracy of CLE in adenomatous polyps diagnosis were 94. 0%, 92. 9%, and 93. 4%, respectively. The positive predictive value was 92.2% and the negative predictive value was 94.5%. The sensitivity, specificity and accuracy of CLE in non-adenomatous polyps diagnosis were 92. 9%, 94.0%, and 93. 4%respectively, the positive predictive value was 94.5% and the negative predictive value was 92.2%.The coherence of CLE and histopathology in adenomatous polyps diagnosis was pretty good (Kappa=0. 893). Conclusion The accuracy of CLE in adenomatous polyps and non-adenomatous polyps differential diagnosis was high, and the coherence with histopathology diagnosis was good, which provided experience for further detection of early rectal precancerous.

Objective The purpose of our study was to report the results of using arthroscopic Remplissage and Bankart repair in patients who had an engaging Hill-Sachs lesion with significant glenoid bone loss. Methods We retrospectively reviewed 49 consecutive patients who underwent arthroscopic Remplissage and Bankart repair for anterior shoulder instability with a mean duration of follow-up of 29.0 months (24-35 months). At the time of surgery the mean age of 42 men and 7 women was 28.4 years. All patients were diagnosed as recurrent anterior shoulder dislocation with a bony lesion of glenoid and an engaging HillSachs lesion. An arthroscopic Remplissage and Bankart repair using metal anchor was performed in all cases.ASES score, Constant-Murley score and Rowe score were used to evaluate the stability and the function of the shoulder. Results Patients' active forward elevation significantly(P=0.007) improved from 162.9°±17.1°preoperatively to 170.9°±7.4° at final follow-up. The external rotation was 56.0°±17.6° before the surgery compared with the 54.1°±17.1° postoperatively(P=0.511 ). The ASES score, Constant-Murley score and Rowe score was 84.7±11.3, 93.3±8.7 and 36.8±8.5 preoperatively compared with 96.0±3.4, 97.8±3.6 and 89.8±12.5 postoperatively. Significant difference could be found with regard to ASES score (P=0.000), ConstantMurley score (P=0.005) and Rowe score (P=0.000). One redislocation happened and a subluxation was noticed in three patients (8.3%). Conclusion Arthroscopic Remplissage combined with Bankart repair can achieve satisfactory for recurrent anterior shoulder dislocation accompany with engaging Hill-Sachs lesion.
