ObjectiveTo investigate the safety and efficacy of carbon dioxide ( CO2 ) insufflation during ERCP.MethodsBetween January and August 2011,a total of 102 consecutive patients who underwent ERCP were randomized to accept CO2 insufflation ( n =52 ) of air insufflation ( n =50 ) during the procedure.ERCP was carried out with the same instrument by an expert endoscopist who was blinded to the insufflation gas used and the procedure was controlled at 30 minutes to 1 hour.The heart rate,oxygen saturation of the patient was continuously monitored during the procedure.Before the procedure and 1 hour after the end of operation,abdominal X-ray was taken to evaluate the width of intestine,and the degree of intestinal expansion was defined as normal,mild,moderate and severe according to the width increased.A questionnaire with 100 mm visual analogue scale (VAS) was used to quantify the abdominal pain and distention experienced at 1 hour,2 hours,and 6 hours after the procedure.The patients' vital signs,bowel dilatation,the average operating time,abdominal pain score and distention score on VAS,and complications in 2 groups were analyzed.ResultsThe baseline characteristics of 2 groups were comparable.ERCP was successfully performed in all the patients and no complication was observed.In CO2 group,the average operating time,mean heart rate and oxygen saturation were (45.2 ± 10.6) min,( 102.2 ± 10.3 ) bpm and ( 99.5 ± 0.5)％,which were (48.5 ± 11.2) min,( 100.3 ± 11.4) bpm and (98.9 ±0.6)％,respectively,in air group.There were no significant differences on these items between the 2 groups ( P ＞ 0.05 ).Moderate to severe intestinal expansion 1 hour after ERCP was found in 14 patients (26.9％ ) in CO2 group and in 28 patients (56.0％ ) in air group,and the latter was significantly higher than the former (x2 =11.61,P =0.009).Both of the mean abdominal pain and abdominal distention scores at 1 hour post-ERCP in CO2 group were lower than those in air group,but without significant difference (P ＞0.05).However,the mean abdominal pain scores at 2 hours and 6 hours post-ERCP in CO2 group were significantly lower than those of patients in air group (7.4 ±2.2 vs.18.7 ±4.6 at 2 hours post-ERCP,9.6 ±3.7 vs.20.1 ±4.5 at 6 hours post-ERCP,all P ＜ 0.05 ).Similarly,the mean abdominal distention scores at 2 hours and 6 hours post-ERCP in CO2 group were significant lower than those of patients in air group (7.6 ±3.6 vs.18.3 ±4.1 at 2 hours post-ERCP,8.9 ±3.7 vs.19.4 ±4.2 at 6 hours post-ERCP,all P ＜0.05).ConclusionThe use of CO2 insufflation instead of air during ERCP appears to be safe.Insufflation of CO2 during ERCP palliates the intestinal expansion,post-ERCP abdominal pain and distention comparison to insufflation of air.However,because of the single-center clinical observation with limited number of cases,the safety and efficacy of CO2insufflation during ERCP requires to be further evaluated.

Background In recent years,with the contiunous progress of the refractive surgery,the operation skill of phakic intraocular lens(PIOL)implantation for correcting extreme high myopia,astigmatism,farsightedness have made greater progression,and its security,effectiveness in clinical attract much more attention. Objective This study was to evaluate the efficacy,safety and stability of Toric Implantable Collamer Lens(TICL)for extreme high myopic astigmatism. Methods This retrospective case series included 33 eyes of 27 patients from May 2008 to February 2009.A TICL was intraocularly implanted via a 3 mm clear corneal incision after paraocular anesthesia.Patients were examined preoperatively and followed-up at 1 day,1 week,1 month,3,6,12 and 18 months postoperatively.The examinations included uncorrected visual acuity,best corrected visual acuity(BCVA),slit lamp examination,refraction,intraocular pressure,endothelial cell morphometry,etc.The written informed consent was obtained from each patient before any medical procedure. Results The uncorrected visual acuity in 96.97% eyes was equal or improved after operation in comparison with BCVA of preoperation.The spherical refraction was within-1.00 D-+0.25 D.The cylinder refraction was within-1.00 D-0 D.The axial deviation of TICL within 10 degree was 93.94%(31/33).No significant differences were found in the intraocular pressure and endothelial cell morphometry between preoperation and postoperation(intraocular pressure:F=3.35,P=5.49;endothelial cell morphometry:t=1.835,P=0.082).The visual acuity and refraction were stable during the follow-up.Astigmatic axial rotation required surgical intervention on one eye.One eye occurred high intraocular pressure because of bigger TICL diameter.The intraocular pressure returned to normal after TICL was exchanged.No cataract occurred during the follow-up duration. Conclusion TICL implantation appears to be an effective,safe and reliable method for extreme high myopic astigmatism.

Objective To explore the effects of application of probiotics on intestinal flora and related cytokines in infants with cholestatic liver disease.Methods (1) Eighty-four infants with cholestatic liver disease had been hospitalized from October 2010 to June 2011 in the First Hospital of Guangxi Medical University.The infants with cholestatic liver disease were randomly divided into the probiotic intervention group and the non-probiotic intervention group.Quantification of intestinal bacteria was detected by SYBR Green Ⅰ real-time fluorescent quantitative polymerase chain reaction,then the number of 3 kinds of bacteria before and after the treatment was compared.(2) The indices of liver function,blood ammonia,cholesterol were detected.The levels of serum transforming growth factor-β1,tumor necrosis factor-α(TNF-α)and interleukin-6 (IL-6) were measured by enzyme linked immunosorbent assay.Results (1) The number of bifidobacterium,lactobacillus and bifidobacterium/escherichia coli (B/E) were significantly increased (all P ＜ 0.01),whereas the number of escherichia coli was significantly decreased in the probiotic intervention group(P ＜ 0.05),however,there were no differences in the non-probiotic intervention group(all P ＞ 0.05).(2)The indices of total billirubin,direct billirubin,γ-Glutamyltransferase,total bile acid,alanine aminotransferase,blood ammonia,alkaline phosphatase were significantly improved after therapy in 2 groups (all P ＜ 0.05).The levels of TNF-α and IL-6 were significantly decreased in the probiotic intervention group (t--7.31,P =0.00;t =-2.90,P =0.01),but there were no differences in the non-probiotic intervention group.The level of BA was significantly decreased in the probiotic intervention group than the non probiotic intervention group (t =-8.37,P =0.00).(3) The B/E value were significantly inverse correlated with level of serum IL-6 (r =-0.796,P =0.01).Conclusions It may help to restore the intestinal flora and balance the immune function in infants with cholestatic liver disease after application of probiotics.

OBJECTIVETo observe clinical effect of integrated Chinese medical (CM) treatment (as maintenance therapy) on the progression-free survival (PFS) and overall survival (OS) in patients with advanced non-small-cell lung cancer (NSCLC) after first-line chemotherapy.

METHODSThe study was a prospective, randomized, controlled clinical trial. Totally 69 non-progressive advanced NSCLC patients treated with first-line chemotherapy were randomly assigned to the test group (34 cases) and the control group (35 cases). Patients in the control group were treated with one Western drug chemotherapy (Gemcitabine or Alimta or docetaxel). Those in the test group were treated with integrated CM treatment (CM decoction, CM Intravenous preparation, and point application). Each cycle consisted of 21 days. Treatment lasted till the disease progressed, or intolerable toxic/adverse reactions occurred, or patients refused to continue the treatment. Patients' life spans were regularly followed-up.

RESULTS(1) The median cycle of maintenance therapy was 2 cycles for two groups with no statistical difference (P =0.274). The median PFS was 12.43 weeks in the test group and 10.00 weeks in the control group, showing statistical difference (P =0.025). The middle survival time (MST) was 18.8 months in the test group and 16.73 months in the control group, showing no statistical difference (P =0.437).

CONCLUSIONCM treatment (as maintenance therapy) showed quail effect to one Western drug chemotherapy in prolonging patients' life span.

Testing of hypothesis was affected by statistical analysis set division which was an important data management work before data base lock-in. Objective division of statistical analysis set under blinding was the guarantee of scientific trial conclusion. All the subjects having accepted at least once trial treatment after randomization should be concluded in safety set. Full analysis set should be close to the intention-to-treat as far as possible. Per protocol set division was the most difficult to control in blinded examination because of more subjectivity than the other two. The objectivity of statistical analysis set division must be guaranteed by the accurate raw data, the comprehensive data check and the scientific discussion, all of which were the strict requirement of data management. Proper division of statistical analysis set objectively and scientifically is an important approach to improve the data management quality.
