Objective To observe the effect of chewing gum on EGG,blood motilin and anus exhausting after laparoscopic abdominal surgery. Methods 200 patients after laparoscopic cholecystectomy were randomly arranged into chewing gum group (Group G): to start chewing gum for 30 min at breakfast time on first day after operation, and also at lunch and dinner time, and stopped until the first anus exhausting, and the control group(Group C): no chewing gum. The time between endpoint of operation to first anus exhausting was recorded; blood motilin and electrogastrography (EGG)on the morning of 1,2,3 days postoperation after chewing gum was detected. Results The time between endpoint of operation to first anus exhausting was not significantly different between two groups, compared with the control group, blood motilin significantly improved on the first day and the second day,but there was no difference between two groups on 3rd day; EGG was no different in all three days between two groups. Conclusions Chewing gum doesn't improve bowel function after laparoscopic abdominal surgery.

Objective To investigate the expression of Circulating tumor cells ( CTCs ) in peripheral blood cells of patients with different stages of Small-Cell Lung Cancer ( SCLC) ,and to evaluate its significance in early diagnosis of lung cancer metastasis.Methods Thirty-five patients with SCLC ( 12 in limited stage and 23 in extensive stage ) and 25 patients with benign lung disease were recruited at the Shanghai Changhai Hospital from April 2011 to April 2013.Samples were prepared from 7.5 ml peripheral venous blood and collected in CellSave tubes.The CTC counts were determined using CellTracks AutoPrep fluorescence scanning system according to the manufacturers′instructions.The expression of CTCs in peripheral blood of SCLC patients and benign lung disease patients were analyzed.The expression of CTCs in different stages of SCLC was measured and compared.Furthermore, samples were prepared from 2 ml peripheral venous blood by centrifugation.The serum levels of NSE Neuron specific enolase were measured.The relationship between the expression of CTC and NSE was analyzed.Results CTCs positive rates in SCLC were significantly higher than in benign lung disease controls [ Positive rates of CTC≥1 were 80.0%and 12.0%(χ2 =27.003,P<0.000 1),CTC≥5 were 51.4%and 0 (χ2 =18.367,P<0.000 1), CTC≥10 were 34.3%and 0(χ2 =10.714,P<0.001),CTC≥50 were 17.1 and 0(P=0.036,P<0.05), respectively ].CTCs positive rates in SCLC extensive stage were significantly higher than limited-stage [Positive rates of CTC≥1 were 58.3% and 91.3%(P=0.033,P<0.05), CTC≥5 were 65.2% and 25.0%(P=0.035,P<0.05), respectively].The expression of CTCs was significantly correlated with NSE (r=0.743 7, P<0.000 1).Conclusion The expression of CTC in SCLC patients is significantly higher than those in control group , and is closely related to clinical stages , which may provide new clues to early predicting of SCLC metastasis and deterioration.

Objective To investigate the relationship between pure -tone audiometry (PTA ) ,speech dis‐crimination abilities in quiet or in noise and the international outcome inventory for hearing aids (IOI-HA) in pres‐bycusis patients .Methods Twenty presbycusis subjects were tested in this study .Pure-tone audiometry (PTA) and speech discrimination threshold were obtained before being fitted with hearing aids .They weared hearig aids more than six months ,and pure-tone audiometry ,speech discrimination scores in quite(the level = 65 dB SPL) and in noise(signal to noise ratio = 10 dB) were carried out in sound field .A stepwise forward multiple-regression analysis was performed to investigate the impact of PTA and speech discrimination scores to IOI-HA .Results The PTAs before or after hearing aid fittings showed a negative association with IOI-HA ,while speech discrimination scores in quiet or in noise before or after hearing aid fittings showed a positive association with IOI-HA .Speech discrimination threshold in noise was identified as a single predictor of IOI-HA(P<0 .001) .Conclusion The relation between speech discrimination scores in noise and IOI-HA suggests that a poor score might limit the hearing aids outcome .The speech discrimination scores in noise help the clinicians predict the outcomes of hearing aid in real‐ities .

Severe liver disease during pregnancy is uncommon in clinical practice. The most common cause of liver disease during pregnancy is liver dysfunction, with an overall prevalence rate of approximately 3%. Liver disease during pregnancy is classified into the liver diseases directly caused by pregnancy and those co-existing with pregnancy, i.e., pre-existing liver disease or occasional liver disease during pregnancy. A differential diagnosis of pre-existing and co-existing liver diseases may help to improve maternal and fetal outcome. During clinical diagnosis and selection of treatment and intervention measures, priority should be given to the potential impact on mother and fetus. This article introduces the latest research advances in the general information, pathogenesis, treatment, and pregnancy outcome of major liver diseases during pregnancy and elaborates on the risk of pregnancy and related coping measures for patients with pre-existing liver disease, so as to guide clinical diagnosis and treatment and patient management.

In order to establish the stable andreliable ISSR-PCR System of Lysimachia christinae, L16 (4(5)) orthogonal design, which based on 7 levels of single factor experiment, were used in this study. The variance analysis was carried out by SPSS 19.0, and 5 main factors affecting the reaction system were optimized in 4 levels. The best annealing temperature was selected by the optimized reaction system. And the stability and reliability of this system was tested by 23 samples from different origins. The results showed that the five factors (DNA template, primer, dNTP, Mg2+ and Taq enzyme) were the most impacts on the amplified results of ISSR-PCR of L. christinae. The order of the influence was: primer > Taq enzyme > DNA template > Mg2+ > dNTP. The optimal system, which was determined by multiple comparison on different levels of each factor, was total volume of 25 microL, including DNA template 60 ng, primer 0.3 micromol x L(-1), dNTP 0.2 mmol x L(-1), Mg2+ 1.8 mmol x L(-1), Taq enzyme 1.25 U. The optimal system was stable and reliable tested by 23 samples from different origins. This study lays the foundation for genetic diversity analysis, fine varieties selection and molecular identification of L. christinae, and provides reference for optimization on ISSR-PCR system of other speciesin future.

To explore the alteration of plasma level of IL-18 in patients with leukemia before and after chemotherapy and its clinical significance, the plasma level of IL-18 was determined with ELISA method before and 2 weeks after chemotherapy in 37 leukemia patients, and 18 normal individuals. The results showed that the plasma IL-18 level (153.34 +/- 50.74 pg/ml) in leukemia patients was similar to the level (135.82 +/- 47.00 pg/ml) in normal control, and the IL-18 level in ALL patients was significantly increased (173.3 +/- 34.4 pg/ml), while the IL-18 level in CML patients (111.8 +/- 50.5 pg/ml) was lower than normal level. After chemotherapy, the IL-18 level (100.89 +/- 50.07 pg/ml) was significantly lower than normal level and oneself before treatment. It is concluded that plasma IL-18 levels in leukemia patients are un-homogeneous and IL-18 production decreased after chemotherapy, and immunologic hypofunction in patients with chemotherapy might be related with the decrease of IL-18 and related cytokines.

OBJECTIVETo evaluate the role of different procedures in the treatment of severe ulcerative colitis (UC) requiring colectomy.

METHODSA total of 29 UC inpatients who underwent colectomy at the West China Hospital between January 1996 and December 2008 were included in this study. Except two cases who underwent partial colectomy, patients were divided into total colectomy group (TC group, n=7) and total proctocolectomy group (TPC group, n=20), meanwhile divided into ileal pouch-anal anastomosis (IPAA, n=8) group, straight end-to-end anastomosis (ileoanal or ileorectal and ileostomy) group (n=14)and ileostomy group (n=5). Quality of life (QOL) was assessed using the Cleveland Global Quality of Life (CGQL) instrument.

RESULTSThe complication rate was 60.0% in TPC group and 57.1% in TC group (P>0.05). The recurrence rate was 15.0% in TPC group and 57.1% in TC group (P<0.05). The complication rate was 6/8 in IPAA group and 50.0% (7/14) in straight end-to-end anastomosis group (P>0.05). The frequency of daily bowel movements in IPAA group was significantly lower than that in straight end-to-end anastomosis group at 1 year after the surgery (5.6+/-1.7 versus 9.1+/-2.9, P<0.05). QOL was significantly improved postoperatively for all the patients(P<0.01). Patients who underwent IPAA had a better QOL than those of straight end-to-end anastomosis group (P>0.05).

CONCLUSIONSTPC-IPAA is the ideal procedure of severe UC with acceptable complication rate, satisfactory quality of life and functional outcome.
