Operation is always thought to be the soul way to cure hepatocelluar carcinoma(HCC),but there are only 30% patients who have the opportunity to receive the operation.Transcatheter hepatic arterial cheomoembolization is the most extensive non-surgery approach to treat hepatocelluar carcinoma which also has a lot of shortcoming and limitation.It is common sense that enhancement of effectiveness of liver cancer therapy largely depends on the combined therapy.

Purpose To explore the expression of Bmi-1, p14ARF and Mdm2 in colorectal carcinoma and to find out their association with clinicopathological features. Methods The expression of Bmi-1, p14ARF and Mdm2 was detected by immunohistochemistry in 125 cases of colorectal carcinoma and 20 cases of normal colorectal tissues. Results ( 1 ) The positive rates of Bmi-1 and Mdm2 were 56. 8% and 62. 4% in colorectal carcinoma, respectively, which were much higher than that in normal colorectal tissues (20. 0% and 15. 0%). The positive rates of p14ARF was 47. 2% in colorectal carcinoma, which was much lower than that 75. 0% in normal colorec-tal tissues ( P<0. 05 ) . ( 2 ) The expression of Bmi-1 was significantly correlated with serosal invasion, lymph node metastasis and Dukes stage. The expression of p14ARF was significantly correlated with serosal invasion and Dukes stage. The expression of Mdm2 was significantly correlated with histologic grade, lymph node metastasis and Dukes stage (P<0. 05). (3) In colorectal carcinoma, the expression of Bmi-1 and Mdm2 was negatively correlated with p14ARF, respectively (P<0. 05). Conclusions Abnormal expression of Bmi-1, p14ARF and Mdm2 is involved in the occurrence, development and metastasis of colorectal carcinoma, which could be as the reference factors in judgement of biological behavior and provide a new target for clinical treatment.

Objective To explore the change of thyroid hormones and leptin at hyperuricemia (HUA)/gout.Methods A total of 96 primary gouts,65 HUAs,and 59 healthy examiners was selected.Height,weight,blood pressure,renal function,serum uric acid(SUA),glucose,lipid profiles,insulin,thyroid hormones were measured after an overnight fast.Results (1) The prevalence of subhypothyriodism at gout and HUA was 7.29％ and 15.38％,respectively.They were higher than that at healthy subjects.(2) Body mass index (BMI),systolic blood pressure (SBP),triglyceride (TG),cholesterol (CHO),thyroid stimulating hormone (TSH),fasting insulin (FINS),homeostasis model assessment of insulin resistance (HOMA-IR),and serum leptin level were increased remarkably at gout/hyperuricemia relative to control group,whereas,free thyroid hormone (FT4) was decreased.(4) In the gout and hyperuricemia groups,TSH was used as the dependent variable for the linear multivariate regression analysis,the results showed that sex,age,BMI,SUA,FT4,HOMA-IR,and Leptin were included in the regression equation of TSH (βwere-0.27,0.832,0.946,0.198,-0.942,0.895,and 0.650,respectively).Conclusions The prevalence of subhypothyroidism in primary gout/hyperuricemia was increased.Female,age,BMI,SUA,FT4,HOMA-IR,and leptin were the independent risk factors.Insulin resistant and leptin played the media roles in the gout/HUA and hypothyroidism.

Objective To investigate the impact of high plasma LDL-C level with or without metabolic syndrome(MS) on the incidence of stroke in Chinese adults. Methods Totally 42 626 subjects (25 -75 years old) from Chinese National Health and Nutrition Survey in 2002 were stratified four groups based on plasma LDL-C level: < 2. 00 mmol/L group, 2. 00 -2. 50 mmol/L group, 2. 51 -3.31 mmol/L group, and ≥ 3.32 mmol/L group. The prevalence of MS (with 2005 International Diabetes Federation criteria) and stroke and the risk factors of stroke were compared among the four groups. Results ( 1 ) The prevalence of MS and stroke increased with rising of LDL-C level. The prevalence of MS in LDL-C≥3. 32 mmol/L group increased 2. 5 times (7, 9% vs 20. 1% ) as compared with that in LDL-C < 2. 00 mmol/L group and the prevalence of stroke increased 4. 2 times(0. 5% vs 2. 1% ), all P <0. 01. (2) In subjects with similar LDL-C level, the prevalence of stroke was significantly higher in a subgroup with MS than that without (P <0. 01 ). (3) After adjustment for age, sex and smoking, logistic regression analysis showed that both LDL-C level and MS were positively associated with the development of stroke; the odds ratio (OR) was 2. 35 and 3. 15 ( P < 0. 0001 ), respectively. (4) Compared with the subgroup of LDL-C < 2. 00 mmol/L without MS, OR for stroke in the subgroups of LDL-C 2. 00 -2. 50 mmol/L, 2. 51 -3. 31 mmol/L, and ≥ 3. 32 mmol / L without MS was 1.03, 1. 89, and 2.08, whereas the OR for stroke in the subgroups with MS and similar level of LDL-C was 4. 38, 5.23 and 6. 15 ; this indicated that the risk of stroke in subjects with MS increased by 3 - 4 times compared with subjects without ( P < 0. 0001 ). Conclusion Both high LDL-C level and MS are independent risk factors of stroke, but the risk of stroke will be further increased in the presence of high LDL-C level plus MS. It is suggested that combined intervention therapy of LDL-C and MS will play an important role in the prevention of stroke.

Objective To study the effects of different oxytocin doses on neonatal pathologic jaundice.Methods A total of 386 newborn infants with normal term of labor were selected from the full-term pregnant women who were admitted to Jiaxing Maternal and Child Health Care Hospital from August 2014 to September 2015 were divided into low dose group (2.5 ~5.0U,n=96), middle dose group (5.0 ~7.5U,n=96), high dose group (7.5~10.0U,n=96) and control group (n=98) according to the different dosage of oxytocin.Total labor time, neonatal gender, neonatal weight and maternal age, as well as the day of birth within seven days of skin side of the bile values were recorded.The probability of each group of neonatal patients with pathological jaundice and the relationship with oxytocin doses were studied.Results The incidence of neonatal pathologic jaundice was 3.23%in the low dose group, 6.67%in the middle dose group, 29.73%in the high dose group and 3.16%in the control group.The differences among low dose group, middle dose group and control group were not significan.Compared with high dose group, the incidence of neonatal pathologic jaundice in low dose group, middle dose group, and the control group were all lower(P<0.05).Conclusion Oxytocin less than 7.5U in labor has no significant effect on neonatal pathologic jaundice, >7.5U can promote pathologic jaundice.

The clinical data and routine biochemical parameters of 64 maintenance hemodialysis (MHD)patients and 20 controls were analyzed in the study.Serum cystatin C levels were detected by latex particle enhalice inununo-turbidimetry:and the cardial structure and function were assessed by echocardiography.As MHD time extended,the levels of semm cystatin C increased gradually,accompanied with high incidence of left ventricular hypertrophy(LVH).The LVH-positive patients had higher systolic blood pressure and left veHtricular mass index,and had higher serum cystatin C than tllose in LVH-negative patients.The serum cystatin C levels were positively correlated with left yentricular mass index(r=0.633,P<0.01)and systolic blood pressure(r:0.397,P<0.01).The results suggest that serum cystatin levels may be an influencing factor for long-term cardiacvascular complication in MHD patients.

Objective To investigate the effect of globular adiponectin on the high expression of monocyte chemotactic protein-1 (MCP-1) induced by high glucose in rat renal tubular epithelial cells (NRK52E),and its relationship with adiponectin receptors and p38MAPK.Methods NRK52E cells were cultured in vitro and divided into six groups:normal glucose group (NG,5.6 mmol/L glucose),high glucose group(HG,25 mmol/L glucose),gAd groupl (HG+gAd 2 mg/L),gAd group2 (HG+gAd 5 mg/L),gAd group3 (HG+gAd 10 mg/L),p38MAPK antagonist group:(SB,HG+SB203580 10 μmol/L).The protein expression of phosphorylated p38MAPK (p-p38MAPK),total p38MAPK (t-p38MAPK),MCP-1 and AdipoR1/AdipoR2 were examined by western blotting.The mRNA expression of MCP-1 and AdipoR1/AdipoR2 were detected by RT-PCR and real-time PCR respectively.Results Compared with NG group,the mRNA and protein expression of MCP-1 increased significantly in HG group (all P＜ 0.05).The phosphorylation of p38MAPK increased (P＜ 0.05) with no change in t-p38MAPK protein.The addition of gAd or SB203580 inhibited the unregulation of MCP-1 and p-p38MAPK induced by HG.Two kinds of adipoR,adipoR1 and adipoR2,were all detectable in NG group,and mRNA and protein expression of adipoR1 was higher than that of adipoR2 (P＜ 0.01).Compared with NG group,the expression of adipoR decreased in HG group,but the difference had no statistical significance(P ＞ 0.05).Compared to HG group,the mRNA and protein expression of adipoR1 increased in gAd groups (all P ＜ 0.01).Conclusion The gAd can dose-dependently attenuate the overexpression of MCP-1 induced by high glucose,and this protective effect may be mediated by adipoR1 and p38MAPK.

Objective To compare the efficacy of intralesional glucocorticoid injection with a needle-free injector versus an ordinary injector for the treatment of keloid. Methods A total of 60 patients with keloid were enrolled and randomly divided into two groups by using a random number table to receive intralesional injection of compound betamethasone with a needle-free injector(n=31)or an ordinary injector(n=29). The injection was given at a dose of 0.2 ml/cm3 once every 3 weeks for 3 sessions. Parameters for therapeutic efficacy were assessed, adverse reactions were recorded, and clinical pictures were taken before and after each treatment. Statistical analysis was carried out by the Mann-Whitney U test and chi-square test with the SPSS 19.0 software. Results Compared with the ordinary injector group, the needle-free injector group showed significantly different injection time during the first and second treatment (U=299.000, 773.500, respectively, both P=0.000), as well as duration of pain after the first injection(U=730.000, P=0.003). After three sessions of treatment, there was a significant difference in the volume, height, hardness of keloid, scores for pain, itching and appearance, and number of injection points between the needle-free injector group and ordinary injector group (U=295.000, 336.500, 264.000, 464.000, 451.500, 308.000, 233.500, P=0.001, 0.007, 0.000, 0.041, 0.043, 0.003, 0.001, respectively). No significant differences were observed in the incidence of adverse reactions between the two groups(all P>0.05). Moreover, the interval for lesion recurrence was significantly shorter in the needle-free injector group(11.8 days, 95%CI:10.96-12.6 days)than in the ordinary injector group(21.2 days, 95%CI:13.96-28.45 days). Conclusion Compared with the ordinary injector, the needle-free injector shows better efficiency for the treatment of keloid with decreased difficulty in injection and improved compliance in patients.

Objective To investigate the differences between Monte Carlo (MC) calculated doseto-water (Dw) and dose-to-medium (Dm) for lung cancers treated with intensity-modulated radiotherapy (IMRT).Methods A total of 10 lung carcinoma patients with 5-field IMRT treatment plans were stratified sampling randomly selected for this study,which were performed on Monaco treatment planning system (TPS) with MC algorithm.Using the patients' own CT images as quality assurance (QA) phantoms,two kinds of QA plan were calculated,one was the Dm,and another was the Dw plan.Dose volume histogram (DVH) parameters and the subtraction of two plans were used to evaluate the spatial distribution of the difference between the Dm and Dw.Results Differences between dose-volume indices computed with Dm and Dw for the PTV65 and PTV50 doses (D50％,D98％ and D2％) were-0.3％,-0.2％,0.3％ and 0.1％,-0.6％,0.4％,respectively,of which the D50％ of PTV65 and D98％ of PTV50 had statistical difference (t =-2.536,-3.776,P ＜ 0.05).For normal tissues,spinal cord,heart,lung and esophagus,the D50％ differences between Dm and Dw were 0.3％,1.1％,-0.2％ and -0.1％,of which the Dm of spinal cord and heart were slightly lower than the Dw (t =2.535,3.254,P ＜ 0.05).For the D2％ of the normal tissues,the differences were 0.3％,-0.6％,-0.7％ and 0.6％,the differences were statistically significant (t =2.311,-4.105,-3.878,6.214,P＜0.05).All the differences were within 2％.Meanwhile planned subtraction analysis showed the differences between the Dm and Dw varied very much with the other body parts of the patient,especially for bone tissues,and the two doses were significant difference (＞ 5％).Conclusion In the course of clinical application,the relative differences between Dm and Dw for lung cancers MC calculations should be noted when considering the dose limitations of bone tissue.
