Objective To explore the effect of cisapride combined with polyethylene glycol electrolytic solution on preoperative bowel preparation for patients receiving colorectal cancer operation. Methods One hundred and fifty-two patients received colorectal cancer opera-tion in our hospital from October 2010 to October 2014 were selected. Those who were treated with cisapride combined with polyethylene gly-col electrolytic solution for bowel preparation before operation were assigned to oberservation group(n=83),those who were treated with poly-ethylene glycol electrolytic solution for bowel preparation before operation were assigned to control group(n=69). The side effect after medi-cation, electrolyte concentration and incidence of incision infection between groups after operation were collected and compared. Results The incidence of nausea and vomiting was 7. 23% in observation group,which was significantly lower than 18. 84% in control group (χ2 =4. 64,P=0. 03). The difference of Na+,K+ and Cl- concentration between groups were not significant (t=1. 83,P=0. 07;t=0. 42,P=0. 68;t=1. 86,P=0. 07). The body temperature,leukocyte count and incidence of incision infection after operation in observation group were significantly lower than those in control group (t=2. 68,P<0. 01;t=3. 29,P<0. 01;χ2 =4. 90,P=0. 03). Conclusion Cisapride com-bined with polyethylene glycol electrolytic solution before operation can significantly decrease the incidence of gastrointestinal side effect after medicaiton and incision infection after operation and it is beneficial to recovery for patients with colorectal cancer operation.

Objective To summarize our experience in the management of cardiopulmonary bypass (CPB) with deep hypothermic circulatory arrest (DHCA) during aortic arch surgery.Methods From March 2007 to May 2010,58 consecutive patients,including 24 urgent and 34 selective operations underwent aortic arch surgery.Thirty-nine hemiarch and 19 total aortic arch replacement operations were performed.CPB was established by perfusion through femoral artery (42 cases) and right subclavian artery (RSA) ( 16 cases),of which 4 cases were carried out with antegrade cerebral perfusion (ACP).Results The mean CPB time was ( 208.88 ± 136.45 ) min.The mean cerebral circulation arrest was ( 27.36 ± 11.50 ) min.Nasopharyngeal and rectal temperature were ( 16.01 ±2.67)℃ and ( 19.72 ±2.13)℃ respectively before DHCA was initiated.The mean times for cooling and rewarming were ( 50.91 ± 16.89) min and ( 88.97 ± 43.68 ) min.The mean time of intubation was (56.70 ± 45.19 ) h.The time in ICU was ( 5.68 ± 5.31 ) d,and the time of hospitalization was (30.11 ± 22.27 ) d.Acute renal failure,hypoxemia,and paraplegia occurred post-operatively in 4,19,and 2 patients,respectively.Four patients died post-operatively with a mortality of 6.90%.Compared with those received hemiarch replacement operation,the patients received total aortic arch replacement had statistically longer time of CPB([262.16 ±219.97]min vs [182.92 ±53.81] min,t =2.14,P <0.05),cerebral circulatory arrest ( [30.47 ± 15.86 ] win vs [25.85 ± 8.48 ] min,t =2.40,P < 0.05 ),rewarming ( [110.00 ± 68.66 ] min vs [78.72 ± 17.31 ] min,t =2.69,P < 0.05 ),and intubation ( [93.95 ± 131.89 ] h vs [38.08 ± 30.70 ] h,t =2.50,P < 0.05 ).There was no significant difference in the times of these procedures between emergency surgery group and elective surgery group,between RSA and femoral artery cannulation groups.Conclusion It is crucial that the cooling and re-warming procedures during aortic arch surgery should be carried out slowly,gradually,and completely when DHCA was adopted alone.conclusion through right axillary artery or RSA was preferred for ACP,in order to accomplish the body circulation arrest at a relative high temperature,to shorten the CPB time,and to alleviate potential harmful effects of hypothermia.Meticulous management of CPB is one of the most important measures to improve the patients' outcome.

Objective To establish a noninvasive prenatal testing(NIPT) method based on the chromosome specific site sequencing instead of the conventional whole genome sequencing.Methods Blood plasma samples from 200 pregnant women with known fetus karyotypes were collected.First,the specific loci on chromosome 13,18 and 21 were selected by the database filter.Then,these specific loci were captured by probes,and were performed sequencing.Finally,chromosome aneuploidy was identified by the Z-score.ResultsSeven fetuses with 21-trisomy syndrome,3 with 18-trisomy syndrome and 1 with 13-trisomy syndrome were detected by the chromosome specific site sequencing,and the results were accordant with those of the whole genome sequencing method.Conclusion The NIPT method based on the chromosome specific site sequencing has the advantages of low cost and high throughput,which may replace the NIPT method based on the whole genome sequencing.

CD4+T cells have strong plasticity and can be polarized intovarious effector cells such as Th1,Th2,Th17 and Treg cells.Then they participate in the regulation of various inflammatory diseases.Its polarization can not only promote development of disease,but also inhibit progression of disease.Direction of polarization may also be different in different diseases or in different stages of the same disease.Therefore,this review aims to summarize and explore the regulatory role of CD4+T cell polarization in different inflam-matory diseases and its significance for disease prevention and treatment.

OBJECTIVE To analyze the data of non-invasive prenatal testing based on specific loci of circulating cell-free fetal DNA (cffDNA). METHODS Selected loci of target chromosomes were analyzed by sequence capture and sequencing. Meanwhile, 600 loci were selected from other chromosomes for determining the concentration of cffDNA. RESULTS A total of 768 specific loci were captured on chromosomes 21 and 18, and used to determine whether the two were abnormal. When the minimum concentration of detected cffDNA was set at 3% and the threshold of Z score was set to [-6,6], the specificity of the analysis was 99.37% and the sensitivity was 100%. CONCLUSION A reliable, convenient and low-cost analytical method has been developed. The method requires less sequencing data for non-invasive prenatal testing, and can accurately detect abnormalities of fetal chromosomes 21 and 18, and simultaneously determine the concentration of cffDNA.

OBJECTIVETo observe the impact of plant sterol esters (PSE) mixed in low fat milk powder (2.5 g of PSE/day) on plasma cholesterol levels in hypercholesterolemic subjects during a 6-week intervention period.
METHODSIn this double-blind, randomized, placebo-controlled study, 59 subjects (19 males, mean age (60.28 ± 6.98) years) with primary hypercholesterolemia (fasting LDL cholesterol between 3.4-6.0 mmol/L) were randomly divided into two groups (treatment group, 2.5 g of plant sterol esters a day, n = 30) and placebo group (n = 29). Blood samples were collected at week 0, 3 and 6. The primary outcome was change in plasma LDL-cholesterol (LDL-C). Secondary outcomes were changes in total cholesterol (TC), HDL cholesterol (HDL-C), triglycerides (TG), anthropometry and blood biochemistry.
RESULTSLDL-C significantly reduction from baseline (4.18 ± 0.54) mmol/L to (3.44 ± 0.61) mmol/L (-17.7%, P < 0.05) at week 3 and (3.35 ± 0.39) mmol/L (-19.9%, P < 0.05) at week 6 in the treatment group, whereas in placebo group from (4.11 ± 0.54) mmol/L at baseline to (3.47 ± 0.60) mmol/L (-15.57%, P < 0.05) and (3.61 ± 0.39) mmol/L (-12.17%, P < 0.05) at week 3 and week 6, respectively. TC was reduced from (6.30 ± 0.86) mmol/L at baseline to (5.92 ± 0.75) mmol/L (-6.03%, P > 0.05) at week 3 and (5.43 ± 0.77) mmol/L (-13.8%, P < 0.05) at week 6 in treatment group, from (6.20 ± 0.76) mmol/L at week 0 to (5.70 ± 0.76) mmol/L (-8.06%, P < 0.05) at week 3 and (5.84 ± 0.75) mmol/L (-5.81%, P < 0.05) at week 6 in placebo group. PSE-enriched milk did not affect plasma HDL-C level and TG level at both week 3 and week 6. After normalization to the placebo group, the treatment group showed significant reduction in LDL-C and total cholesteron after 6 weeks. The observed difference of reduction was 7.69% (-0.33 mmol/L, P < 0.05) for LDL-C and 8.00% (-0.51 mmol/L, P < 0.05) for TC between the two groups. There were no significant changes in safety parameters, including blood biochemistry tests during the study period.
CONCLUSIONPlant sterol ester enriched milk powder is effective in reducing LDL-C among Chinese hypercholesterolemic subjects at a dosage recommended by EFSA.
