Objective To explore the relationship between the expression levels of excision repair cross complementation group 1(ERCC1), breast cancer susceptibility gene 1(BRCA1), thymidylate synthase (TS) mRNA and clinicopathological features, prognosis in advanced colorectal cancer, and the correlation between the expression levels of ERCC1 and BRCA1. Methods The expression levels of ERCC1, BRCA1 and TS mRNA of postoperative paraffin embedded tissue were tested by real-time quantitative reverse transcription polymerase chain reaction (RT-PCR) in 49 advanced colorectal cancer cases. The results were analyzed by χ2 test of the correlation between the expression levels and clinicopathological characteristics. Patients were followed up by clinic or telephone. The prognosis was analyzed by small sample Kaplan-Meier survival analysis and Log-rank time series analysis, and P<0.05 was statistically significant. Results The expression level of ERCC1 mRNA in patients with colorectal carcinoma had no obvious correlation with the clinical and pathological characteristics such as gender, age, tumor location, lymph node metastasis, distant metastasis, CEA and differentiation degree (P>0.05). The expression level of BRCA1 mRNA had no significant correlation with the above clinical and pathological features (P>0.05) except distant metastasis (P=0.030) and differentiation degree (P=0.002). The expression level of TS mRNA had no significant correlation with the above clinical and pathological features (P>0.05) except distant metastasis (P=0.003). The expression level of ERCC1 and BRCA1 mRNA obviously correlated (P=0.002). The 1 year overall survival rate was 95.92%(47/49);the 2 year overall survival rate was 83.67%(41/49);and the 3 year overall survival rate was 73.47%(36/49). Overall survival and progression-free survival time in ERCC1 mRNA low expression group (47.8, 41.0 months) was higher than that in ERCC1 mRNA low expression group (27.3, 20.0 months) respectively (P=0.001, P=0.001). Overall survival and progression-free survival time in BRCA1 mRNA low expression group (43.7, 42.7 months) was higher than that in BRCA1 mRNA high expression group (29.3, 25.1 months) respectively (P=0.009, 0.006). Overall survival time in TS mRNA low expression group (39.8 months) was higher than that in BRCA1 mRNA high expression group (25.2 months). Conclusions The expression level of ERCC1 mRNA is not correlated with its clinical and pathological characteristics, but with its biological characteristics. BRCA1 and TS levels are correlated with invasion and metastasis. Low levels of ERCC1 and BRCA1 expression have a better prognostic effect on platinum based first-line chemotherapy for advanced colorectal cancer, and they are correlated. Low level of TS also has longer disease-free survival. Three joint detection could be used as a prognostic factor for colorectal cancer chemotherapy.

Objecthe To equate the effects of recombinant human growth hormone (rhGH) on serum albumin lewis and intestinal mucosal morphology in rats with intracerebral hemorrhage. Methods A rat model of intracerebral hemorrhage was induced by autologous blood injection. Fifty-six SD rats were divided into sham-operation group (n =8), rhGH group (n =24; intraperitoneal injection of rhGH, 1 U/kg, once a day), and saline control group (n =24; intraperitoneal injection of equivalent normal saline, once a day). The rhGH and saline control groups were redivided into 1-, 7- and 14-day groups (n =8 in each group) after the procedure. The serum albumin concentration was detected at different time points in all groups. The changes of intestinal mucosal morphology were observed with Hematoxylin and Eosin (HE)staining and image analysis. Results Hie serum albumin lewis at all time points of intracerebral hemorrhage in the saline control group were all significantly lower than those in the sham-operation group (all P < 0. 01); The serum albumin level was increased gradually with the treatment process in the rhGH group, however, it was only significantly higher than the saline control group at day 14 (39.93 ±1.98 g/L νs. 37. 93 ±1.57 g/L) (P<0. 01). There were no significant differences between the rhGH group and the saline group in intestinal villus height and mucosal thickness at day 1 and 7 after intracerebral hemorrhage, however they were increased significantly at day 14 (P <0.01). The area of intestinal villi was reduced progressively at day 1, 7 and 14 after intracerebral hemorrhage, and with the treatment process the rhGH group was increased more progressively than the saline control group (P <0. 01). The depth of intestinal glands in the rhGH group was increased significantly than that in the saline control group (P <0. 01), but there was no significant difference at day 14; the density of glands in the rhGH group was significantly increased than that in the saline group at day 1 after intracerebral hemorrhage (P < 0. 01), and it was not increased significantly at day 7, however, it was not increased but decreased slightly at day 14. Conclusions The serum albumin level in rats with intracerebral hemorrhage was decreased significantly than that in the sham-operation group, and intracerebral hemorrhage could cause intestinal mucosal injury. rhGH increased the serum albumin level in rats with intracerebral hemorrhage. It might reduce intestinal mucosal injury to different degrees whether it was in the early or late intracerebral hemorrhage, and the late improvement was more significant. The improvement degree of rhGH on intestinal mucosal injury was positively correlated with the increased degrees of the serum albumin level.

Objective To explore the correlation between the serum albumin level and the jejunal mucosal morphology in rats with cerebral hemorrhage and to find out the mechanism of the resulting hypoproteinemia.Methods A rat model of cerebral hemorrhage was used to detect the serum albumin level and the morphologic parameters of jejunal mucosa on day 1,7 and 14 after the hemorrhage.The results were compared to the normal control group and the sham-operated group. The correlation between the serum albumin level and the parameters of the jejunal mucosal morphology was explored.Results The serum albumin level was positively correlated with the small intestinal villous height(r =0.869,P＜0.01),villous area(r=0.659,P＜0.01),mucosal thickness (r=0.915,P＜0.01),depth of intestinal glands(r=0.545,P＜0.05)and density of intestinal glands(r=0.475,P＜0.05).Conclusion The serum albumin level is closely related to the morphologic changes of the jejunal mucosa.

Objective To explore the association between inflammatory cytokines and islet β-cell function in chronic persistent asthma patients. Methods 112 adults with persistent asthma and 60 healthy volunteers were enrolled in this study. According to the severity of disease, all subjects were divided into persistent-mild group and persistent-moderate group. Plasma tumor necrosis factor-α(TNF-α), interleukin6(IL-6) and C-reactive protein (CRP) were determined. Oral glucose tolerance and insulin releasing test were performed. The ratio of the area under the curve of insulin to area under the curve of glucose ( AUC1/AUCG ), homeostasis model assessment for insulin resistance ( HOMA-IR), insulin sensitivity index( ISI),homeostasis model assessment for β-cell function (HBCI) and early insulin secretion index(△I30/△G30)were calculated. The values of forced expiratory volume in l second ( FEV1 ), forced vital capacity(FVC)and FEV1/FVC were recorded. Results In patient groups, the values for plasma TNF-α, IL-6, CRP,AUC1, AUC1/AUCG, HOMA-IR, HBCI significantly increased compared with those in control group, while ISI declined ( t =2. 02～13.62, P ＜0. 05). Multiple step regression analysis showed that HOMA-IR was positively correlated with CRP, LDL-C, BMI, AUC1, TNF-α( P ＜0. 01 orP ＜0. 05), but negatively correlated with FEV1 ( P ＜ 0. 05 ). Conclusion The results indicated that inflammatory cytokines ( TNF-α,IL-6,CRP) might result in insulin resistance in asthma patients who had hyperinsulinism at the same time.

Objective To explore the difference of the expression level of FK506 Binding Protein 51 (FKBP51) in colorectal adenocarcinoma and normal colorectal tissues,and the correlation between FKBP51 expression level and clinicopathological characteristics,and to clarify whether FKBP51 is involved in the occurrence and development of colorectal cancer.Methods By immunohistochemical staining [streptavidin-peroxidase (SP) method] and Western blotting methods tested 31 cases of colorectal cancer tumor tissues and normal colorectal tissues far from tumor 5 cm,and explored the expression level difference of FKBP51.Combined with clinical data of patients,results were analyzed by statistical method x2 test of four case table data.Results The high expression rate of FKBP51 in tumor tissues was 74.19％ (23/31 cases),while the high expression rate of FKBP51 in normal tissue was 9.68％ (3/31 cases).The difference was significant.The expression level of FKBP51 in patients with colorectal carcinoma had no obvious correlation with gender (P =0.771),age (P =0.474),tumor location (P =0.213),degree of differentiation (P =0.318),lymph node metastasis (P =0.124),distant metastasis (P =0.318) and clinical stage (P =0.171);and the tumor size (P =0.049),depth of invasion related (P =0.031),the difference was statistically significant.Conclusions The expression of FKBP51 in colorectal cancer was strong,while weak expression in normal colorectal tissues.With the increase of tumor infiltration and deepening,the expression of FKBP51 became stronger,which indicated that FKBP51 participated in the genesis and development of colorectal cancer,and it might become a new target for individual therapy of colorectal cancer.

Objective To observe the effect of the three active ingredients of a Chinese traditional medicine compound named Kang Fu Ling( KFL) against PC12 cells oxidative damage induced by microwave radiation.Methods PC12 cells were differentiated into neuros induced by nerve growth factor ( NGF ) .PC12 cells were incubated for 48 hours after astragalosides,total paeony glycoside and tanshinones were added at different concentrations (1, 3, or 9 μg/ml) .The cells in the control group were cultivated with the only medium of the same volume.Then, cells were irradiated with 30 mW/cm2 microwave for 6 minutes.The morphology of PC12 cells was observed under an inverted microscope soon before and after irradiation and the cell viability was measured by methylthiazolyl tetrazolium ( MTT) colorimetry.Reactive oxygen species ( ROS ) was determined using active oxygen probe 2′, 7′-dichlorodihyarofluolescen diacetde ( DCFH-DA ) while malonyldialdehyde(MDA) was measured in the homogenate of PC12 cells through thiobarbituric acid ( TBA) reactive substance assay.Results The cell morphology of each group showed no obvious difference.6 h after irradiation, the viability of irradiation control group measured by MTT declined apparently(P<0.01)compared with the normal control group.The 3 μg/ml astragalosides treatment group increased the viability of PC12 cells after microwave exposure ( P <0.01).The contents of ROS and MDA were increased after irradiation(P<0.01).However, in the three active ingredients of Kang Fu Ling treatment groups, both ROS and MDA were much lower than in irradiation control group.Conclusion Astragalosides, total paeony glycoside and tanshinones, which are the three active ingredients of Kang Fu Ling, all have protective effect against PC12 cell injury caused by microwave radiation,possibly by scavenging free radicals and reducing oxidative stress injury.

Evaluation of human gait function is of great significance in clinical medicine and rehabilitation engineering. A quantitative gait evaluation method using principal component analysis was proposed. The evaluation steps included that a series of characteristic index was performed by the gait parameters with a gait detection, and the index was normalized, quantified and summarized by principal component analysis. Then the evaluation results were shown in formulation, figures and tables. The examples showed that this system could evaluate the recovery of the gait by treatment.

A dynamics model of human lower extremity, which combines musculotendon dynamics and muscle excitation-contraction dynamics, is presented. With this model, a motion process of normal gait during swing phase is numerically analyzed by use of the optimal control theory. The model was verified using experimental kinematics, muscles activation, and electromyographic data. The result showed that the tri-phasic activation pattern and synergistic muscles displayed during a normal gait in swing phase. The pattern consists of three distinct phases, i. e., acceleration during moving initiation, braking the moving segment, and posture control at the final specified position.

Objective: To explore the main characteristics of syndromes in traditional Chinese medicine (TCM) in post-stroke depression (PSD) and to provide basis for treatments with TCM herbs. Methods: According to diagnostic criteria of PSD, stroke patients and depression patients from Department of Neurology, First Affiliated Hospital, Anhui University of Traditional Chinese Medicine were assigned into cerebral stroke group (150 cases), depression group (151 cases) and PSD group (123 cases). Neuropsychological assessments and imaging and biochemical analyses were conducted. TCM syndrome differentiation for these diseases was performed. We also determined the characteristics of TCM syndromes of PSD, relative risk of the syndromes and their correlations with ages as well. Results: Scores of qi stagnation and blood stasis, liver qi depression, and transformation of fire due to qi stagnation in PSD group were significant higher than those in cerebral stroke group (P<0.05, P<0.01). In cerebral stroke group, majority of the patients displayed one syndrome, while in PSD and depression groups, the patients had three or more syndromes. Of these syndromes, the incidence rate of syndrome of liver qi depression complicated with transformation of fire due to qi stagnation or flaring of fire due to yin deficiency was high. The syndrome of liver qi depression occurred much more frequently in PSD group and depression group than in cerebral stroke group (P<0.05, P<0.01). The logistic regression analysis showed that the syndrome of qi stagnation and blood stasis had high relative risk to PSD. The syndrome of deficiency of heart and spleen was positively correlated with age in cerebral stroke group. Conclusion: The main TCM syndromes of PSD and depression are qi stagnation and blood stasis, liver qi depression, and transformation of fire due to qi stagnation. The syndrome of deficiency of heart and spleen is closely related to age among the stroke patients. The syndrome of qi stagnation and blood stasis serves as an independent risk factor for PSD. The more complicated the syndromes are, the more serious depression becomes.
