Objective To explore influencing factors for complete resection and operation time of endoscopic submucosal dissection( ESD) for colorectal tumors. Methods This retrospective study included 95 consecutive colorectal tumors in 88 patients whose pathological diagnosis was adenoma and carcinoma, treated with ESD at the Department of Endoscopy of the First Hospital of Jilin University from January 2013 to December 2014. Multiple logistic regression analysis was conducted on the factors related to complete resection and operation time. Results Average tumor size was 28. 7±14. 1 mm(range,8?80 mm), and the average procedure time was 80. 72±63. 90 min. The rate of complete resection was 92. 6%(88/95),and the rate of incomplete resection was 7. 4%(7/95). Multivariate logistic regression analysis revealed that fibrosis (P=0. 012,OR=52. 473, 95%CI:2. 571?1140. 438) contributed to incomplete resection. Fibrosis ( P=0. 001, OR=0. 045, 95%CI:0. 007?0. 289) ,tumor size ( P=0. 035,OR=0. 170, 95%CI:0. 033?0. 884) ,granular?type laterally spreading tumor ( P=0. 013, OR=34. 432, 95%CI:2. 138?554. 476 ) , non?granular?type laterally spreading tumor(P=0. 044,OR=31. 715, 95%CI:1. 093?919. 904) were independent factors for extending operation time of colorectal ESD. Conclusion The severer fibrosis can induce higher rate of incomplete resection. The more severe fibrosis is, the larger tumor size is, and the longer operation time is.

Objective To study the relationship between tyrosine phosphorylation(TP)and protein expression of insulin receptor substrate-1(IRS-1)and insulin resistance in patients with gestational diabetes mellitus(GDM).Methods IRS-1 expression and TP in skeleton muscle tissue were determined by Western blot and immunoprecipitation in women with GDM(GDM group,n=22),normal pregnant women(normal pregnancy group,n=22)and normal nonpregnant women(normal nonpregnant group,n=13).Fasting plasma glucose(FPG)and fasting insulin(FINS)were measured by oxidase assay and immunoradioassay. Results(1)The levels of FPG,FINS,and insulin resistance index were calculated according to homeostasis model assessment [ HOMA-IR;(5.6?0.8)mmol/L,(15.4?5.1)mU/L,and 1.2?0.5 ] in GDM group were significantly higher than those in normal pregnancy group [(4.4+0.5)mmol/L,(10.6 ?3.1)mU/L,and 0.8?0.3;P

OBJECTIVETo explore the effects of integrative medicine (IM) rehabilitation protocolon motor function, activity of daily living, and quality of life (QOL) in hemiplegia patients after stroke.
METHODSTotally 120 patients with post-stroke hemiplegia were allocated to four groups using sealed envalope drawing, i.e., the rehabilitation group, the Chinese medical treatment group, the acupuncture group, and the comprehensive rehabilitation group, 30 cases in each group. Based on routine rehabilitative training, patients in the Chinese medical treatment group, the acupuncture group, and the compre-hensive rehabilitation group received standardized treatment based on syndrome typing, Shi's Consciousness-Restoring Resuscitation acupuncture, Chinese herbs + acupuncture comprehensive rehabilitatino protocol, respectively. The treatmet cycle consisted of 4 weeks with 24-week follow-ups. Fugl-Meyer motor assessment (FMA), Modified Barthel Index (MBI), and Stroke-Specific Quality of Life Scale(SS-QQL), and safety assessment were taken as main effect indices before treatment, at week 4 of treatment, at week 12 and 24 of follow-ups, respectively.
RESULTSThere was no statistical difference in FMA score, MBI score, SS-QOL score among the four groups before treatment (P > 0.05). These scores were significantly improved in the four groups at week 4 of treatment, week 12 and 24 of follow-ups, respectively (P < 0.05). Besides, FMA score and SS-QOL score were significantly improved in the comprehensive rehabilitation group at each corresponding time point, as compared with other treatment groups (P < 0.05).
CONCLUSIONSThe comprehensive protocol could significantly improve motor function, activity of daily living in hemiplegia patients after stroke, and further improve their QOL. Its effect was better than other single treatment.

OBJECTIVETo explore the application value of the high-frequency ultrasound examination of the normal adult sciatic nerve.
METHODSThe high frequency ultrasound was used to examine 60 cases ,a total of 120 normal adult sciatic nerve (28 males and 32 females ranging in age from 19 to 38 years old, averaged 23.8 years old). The age between men and women, height and weight showed no significant difference. The cross-sectional scanning and longitudinal scanning, if necessary, Panoramic Imaging were conducted. The cross section area of sciatic nerve was measured at the hip line, the middle of the thigh, the edge of the popliteal fossa, and the relationship betwen the sciatic nerve and surrounding muscle group was observed in each cross-section. Probe was rotated 90 degree to display the long axis of sciatic nerve, to get the longitudinal section along the long axis from top to bottom. So the sciatic nerve in the vertical axis and the surrouunding muscles was displayed by above method combined with panoramic imaging. The data of coss-sectional area of sciatic nerve were obtained at the central of hip line, the middle of the thigh, the edge of the popliteal fossa, and then were divided into different groups by gender and sides to do statistical analysis.
RESULTSThe applicatic nerve in thigh can be clearly displayed by high-frequency ultrasound in this group of 60 people with 120 nerves, but low display rate of sciatic nerve in hip, approximatley 31.4% (21/66). The longitudinal section of the sciatic nerve displayed as the banded isoechoic or slightly hyperechoic, parallel partial hyperechoic line could be seen in it; in the cross-section, it showed a clear edge of the sieve-like isoechoic or slightly hyperechnie, which could be oval ,trapezoidal, triangular and irregular in shape; the sciatic nerve bad visible passive movement and shape change when muscle contracted. There were statistically significant differences of cross-sectional area of sciatic nerves at the hip line ,the middle of thigh and edge of the popliteal fossa between 56 sciatic nerves in 28 males and 64 sciatic nerves in 32 females (P< 0.05); but there were no significant differences between left and right sides (P>0.05).
CONCLUSIONHigh frequency ultrasound can be used as the first choice of the sciatic nerve when an imaging method preferred.

OBJECTIVEThe relationship between the mode of tumor invasion in the tumor-host borderline and the frequency of cervical lymph node metastasis was investigated in squamous cell carcinoma of the oral cavity.
METHODS200 cases with histologically proven squamous cell carcinoma of the oral cavity were studied by histological method with HE stained. The mode of invasion in the tumor-host relationship was classified into five grades by Yamamoto's criteria.
RESULTSWith regard to the relationship between the mode of invasion and metastasis, the more invasive the tumor tissue was, the more frequent the metastasis formed (P < 0.001). The frequency of metastasis in grades 1 and 2 was low (0 and 5.9%, respectively), The frequency of metastasis in grades 3 was moderate (14.3%), and that in grades 4c and 4d was highly rapid (63.0% and 82.9%, respectively). Single node metastases were frequent in grade 3 and grade 4c (66.7% and 58.8%, respectively), while plural node metastases were frequent in grade 4d (70.6%, P < 0.05). Moreover, the distribution of metastasized lymph nodes was focused on level 1 (41.2%) or level 1 and 2 (79.4%) in grade 4c and was dispersed from level 1 to 4 in grade 4d (P < 0.05). In the present study, the degree of differentiation did not correlate well with the frequency of metastasis.
CONCLUSIONThese results indicate that the more invasive the tumor cells were to the host, the more frequent the metastasis formed. The different mode of invasion would accompany with different frequency of metastasis, different number and distribution of metastasized lymph nodes.
