Objective To investigate the expression of heat shock protein (HSP) 60 and analyze the significance in cervical carcinoma. Methods The cervical tissue samples of 57 cases of cervical cancer and 57 normal cervical tissues were collected. The expression of HSP60 were detected by semi-quantitative reverse transcription polymerase chain reaction (RT-PCR). The protein expressions of HSP60 were determined by Western blot analysis. To observe the relationship between HSP60 expression and the occurrence and development of cervical cancer. Results HSP60 mRNA expression in normal cervical tissue was significantly lesser than that in cervical cancer tissue (t=2.65, P0.05). The levels of HSP60 protein expression in normal cervical tissue was significantly lower than the expression in cervical cancer tissue (t=3.132, P

Objective To investigate the interrelation between nuclear DNA content and the expressions of cyclin D1 and P53 in carcinogenesis of breast carcinoma induced by 7,12 dimethylbenz(a)anthracence(DMBA) in rats. Methods Animal model of breast carcinoma was replicated by gastric perfusion of DMBA at 20 mg/100 g. Nuclear DNA content was detected with image analysis instrument and the expressions of cyclin D1 and P53 at every stage of carcinogenesis of breast carcinoma induced by DMBA in rats observed by Sp immunohistochemical staining. Results In mammary gland tissue at grade Ⅰ, grade Ⅱ and grade Ⅲ atypical hyperplasia of breast carcinoma, there was overepression of cyclin D1(3/20, 6/20 and 11/20, respectively). The overexpression of cyclin D1 was detected to be present in grade Ⅰ, grade Ⅱ and grade Ⅲ breast carcinoma (7/9, 1/4 and 0/7, respectively). The overexpression of P53 was detected to be present in grade Ⅰ, grade Ⅱ and grade Ⅲ breast carcinoma (1/9, 1/4 and 6/7, respectively). Conclusion Nuclear DNA content reflects the state of cell proliferation. Cyclin D1 overexpression participates in the carcinogenesis of breast carcinoma, which may be the early event in breast carcinoma. P53 expression is associated with the development of breast carcinoma, which may be the late event in breast carcinoma. The expression of cyclin D1 is negatively correlated with P53 overexpression.

This paper investigated contamination situation of Listeria monocytogenes(Lm). To compare dif- ferent selectivity enrichment broth for detectable effect of Lm and compare detectable effect in different samples by using different methods, furthermore, choose the best enrichment broth for specific food. One hundred and thirty five random samples from raw meat, aquatic product, fruit and vegetable, quick-frozen food in Baoding. Applied LB enrichment broth, EB enrichment broth, new modification FDA enrichment broth and Fraser enrichment broth before separated by PALCAM selective agar, then identified by interna- tional standard method after PCR. Results: Four methods showed that there were 23 Lm positive, detected 5 Lm by LB method, 6 Lm by Fraser method, 5 Lm by EB method and 7 Lm by new modification FDA method. The total detectable rate of four methods had no large specificity, but to specific kind of food was different.

In order to observe the feature of age-related marrow conversion and maturation of epiphyseal cartilage and analyze the distribution of red and yellow marrow in the proximal femur at STIR MR imaging, STIR and T(1) weighted MR imaging of the proximal femur in 52 subjects, aged 4 months to 25 years old, were retrospectively analyzed for the distribution and appearance of red and yellow marrow. The subjects with no known bone marrow abnormalities were divided into 6 age groups. The signal intensity of the marrow in the proximal epiphysis, proximal metaphysis, proximal diaphysis, distal diaphysis and greater trochanter was compared with the signal intensity and homogeneity of surrounding muscle and fat and graded by two observers. The results showed that the conversion of hematopoietic marrow in the proximal femur followed a well-defined sequence, occurring first in the proximal epiphysis, followed by the distal diaphysis, and then greater trochanter and metaphysis. STIR in combination with T(1)-weighted imaging could display clearly the origin of ossification center and the course of conversion from red to yellow marrow in proximal epiphysis and greater trochanter. STIR imaging showed that the marrow conversion in proximal metaphysic began below epiphyseal plate and intertrochanter. The site of red yellow was distributed in weight-bearing axis by 20 years of age. The marrow conversion of diaphysis was from distal end to proximal end, and the consequence of conversion was that distal diaphysis contained yellow marrow but proximal diaphysis partly red marrow connected with the red marrow of metaphysic. The epiphyseal cartilage had different characters of signal-intensity with age in STIR sequence. The distribution of red marrow in STIR imaging was more close to that of anatomy than T(1)-weighted imaging. It was concluded that STIR could dynamically display the feature of marrow conversion and the development of epiphyseal cartilage and accurately reveal the age-related distribution of red and yellow marrow on STIR imaging in the proximal femur.

Objective To investigate the risk factors resulting in the perioperative liver failure and death for the HBV-associated hepatocellular carcinoma (HCC) patients with or without cirrhosis.Methods The method of retrospective case-control study was performed.The clinicopathological data of 1 083 HCC patients with positive HBsAg who received curative liver resection at the Southwest Hospital from January 2008 to December 2012 were collected.According to the absence or presence of cirrhosis,the HCC patients with positive HBsAg were divided into the 2 groups,including the cirrhosis group (633 patients) and the non-cirrhosis group (450patients).The intraoperative conditions (operation time,volume of intraoperative blood loss,rate of blood transfusion,rate of pringle maneuver) and postoperative conditions (incidence of perioperative complications,duration of postoperative hospital stay,perioperative mortality) of HCC patients were observed.The gender,age,alanine transaminase

maneuver,extent of liver resection,number of tumors,tumor diameter,tumor thrombus and liver cirrhosis were enrolled and prognostic factors resulting in perioperative liver failure and death for the HCC patients were explored.Measurement data with skewed distribution were presented as M (range) and comparison between the 2 groups was analyzed using Mann-Whitney U test.Count data were presented as counts (percentage) and comparison between the 2 groups was analyzed using chi-square test or Fisher exact probability.Univariate analysis was performed by chi-square test and multivariate analysis was performed by Logistic regression model (forward).Results (1) The intraoperative conditions:the volume of intraoperative blood loss were 500 mL (range,30-7 000 mL) in the cirrhosis group and 400 mL (range,50-8 000 mL) in the non-cirrhosis group,with a statistically significant difference between the 2 groups (Z =-2.209,P ＜ 0.05).The operation time,rate of blood transfusion and rate of pringle maneuver were 250 minutes (range,82-715 minutes),29.86％ (189/633),62.24％ (394/633) in the cirrhosis group and 242 minutes (range,85-738 minutes),27.11％ (122/450),66.67％ (300/450) in the non-cirrhosis

infection,abdominal infection and liver failure were 6.48％ (41/633),2.69％ (17/633),5.53％ (35/633) in the cirrhosis group and 3.56％ (16/450),0.89％ (4/450),1.33％ (6/450) in the non-cirrhosis group,respectively,with statistically significant differences between the 2 groups (x2 =4.502,4.465,12.713,P ＜ 0.05).The duration of postoperative hospital stay was 15 days (range,0-70 days) in the cirrhosis group and 14 days (range,0-71 days) in the non-cirrhosis group,with a statistically significant difference between the 2 groups (Z =-3.448,P ＜ 0.05).The perioperative mortality was 5.85％ (37/633) in the cirrhosis group and 2.44％ (11/450) in the non-cirrhosis group,with a statistically significant difference between the 2 groups (x2=7.181,P ＜ 0.05).(3)Results of risk factors affecting perioperative liver failure:①results of univariate analysis showed that age,AST,Alb,Child-Pugh classification,operation time,volume of intraoperative blood loss,blood transfusion,extent of liver resection,tumor diameter,liver cirrhosis with positive HBsAg were associated with perioperative liver failure in HCC patients (x2=5.013,7.979,8.855,16.968,14.148,9.764,18.511,11.749,5.534,12.713,P＜0.05);age,AST,Alb,Child-Pugh classification,operation time,blood transfusion,extent of liver resection and tumor diameter were

perioperative liver failure in the non-cirrhosis group (P ＜ 0.05).②Results of multivariate analysis showed that age≥60 years,Child-Pugh class B,operation time ＞ 360 minutes,blood transfusion,extent of liver resection ≥3 segments and liver cirrhosis were independent risk factors affecting perioperative liver failure in HCC patients with positive HBsAg [OR =2.285,2.716,2.315,2.159,2.459,4.322;95％ confidence interval (CI):1.081-4.831,1.100-6.706,1.064-5.038,1.068-4.362,1.264-9.786,1.763-10.598,P＜0.05];Alb ＜38 g/L,Child-Pugh class B,blood transfusion and extent of liver resection ≥ 3 segments

intraoperative blood loss ＞ 1 200 mL was an independent risk factor affecting perioperative liver failure in the non-cirrhosis group (OR =15.077,95％CI:2.695-84.353,P ＜ 0.05).(4) Risk factors affecting perioperative death:①results of univariate analysis showed that gender,Alb,TBil,Child-Pugh classification,blood transfusion,extent of liver resection,tumor diameter,tumor thrombus and liver cirrhosis were associated with perioperative death in HCC patients with positive H BsAg (x2=4.462,8.783,4.212,4.869,7.189,11.745,6.837,4.323,7.181,P ＜0.05);Alb,extent of liver resection and tumor diameter were associated with perioperative death in the cirrhosis group (x2=12.173,12.793,10.981,P ＜ 0.05);blood transfusion and tumor thrombus were associated with perioperative death in the non-cirrhosis group (x2 =5.836,6.417,P ＜ 0.05).② Results of multivariate analysis showed that Alb ＜38 g/L,extent of liver resection ≥ 3 segments and liver cirrhosis were independent risk factors affecting perioperative death in HCC patients with positive HBsAg (OR =2.560,2.657,2.567,95％ CI:1.382-4.742,1.471-4.800,1.283-5.134,P ＜ 0.05);Alb ＜ 38 g/L,extent of liver resection ≥ 3 segments and tumor diameter≥5 cm were independent risk factors affecting perioperative death in the cirrhosis group (OR =3.003,2.533,3.060,95％ CI:1.495-6.034,1.251-5.128,1.135-8.251,P＜0.05);blood transfusion and tumor thrombus were

for perioperative liver failure and death in HCC patients with positive HBsAg.The risk of perioperative liver failure and death in HCC patients with cirrhosis is significantly higher than that in HCC patients without cirrhosis,and there is a difference in the risk factors for perioperative liver failure and death.

Objective To investigate the efficacy and side effects of 4?-adrenergic receptor(?- AR)antagonists in the treatment of chronic prostatitis/chronic pelvic pain syndrome(CP/CPPS).Meth- ods Totally,325 patients(mean age,33.2 year;disease history,2.4 years)with CP/CPPS were randomly divided into Prazosin(n=95),Terazosin(n=78),Phenoxybenzamine(n=27),and Doxazosin mesylate controlled release tablets(n=72)groups.Some antibiotics and medications were used for allopathy.In addi- tion,53 cases with no?-AR antagonist treatment served as control group.The efficacy and side effects in all the patients were observed and recorded.The chronic prostatitis symptom index(CPSI)was used to evaluate the efficacy.Results In control group,22(41.5%)patients responded well to the treatment( CPSI mark drop≥5)and 31(58.5%)failed to respond to the treatment(CPSI mark drop＜5).In study group,199 (73.2%)patients responded well to the treatment,and 73(26.8%)failed.The difference in efficacy be- tween?-AR antagonists and placebo treatment was significant(P＜0.01).In study group,specifically,the effective rate was 55.6% in Phenoxybenzamine,78.2% in Terazosin,76.4% in Doxazosin mesylate con- trolled release tablets,and 71.6% in Prazosin groups.The main side effects of?-AR antagonists were postur- al hypotension(a rate of 23.2% for Prazosin,17.9% for Terazosin,22.2% for Phenoxybenzamine,and 8.3% for Doxazosin mesylate controlled release tablets)and dysfunction of ejaculation(only in Phenoxy- benzamine group with a rate of 51.9%).The rates of withdrawing treatment due to side effects were in turn 18.5% of Phenoxybenzamine,7.4% of Prazosin,5.1% of Terazosin,and 0% of Doxazosin mesylate con- trolled release tablets.Conclusions As essential medications for the treatment of CP/CPPS,?-AR antag- onists can relieve the clinical symptoms(dropping NIH-CPSI mark significantly),but some side effects should be considered when some medications are selected.

OBJECTIVETo evaluate the efficacy of late accelerated hyperfractionated conformal radiotherapy (LACF) combined with capecitabine on esophageal carcinoma.

METHODSOne hundred and sixty eight patients of esophageal cancer were randomly divided into 3 groups, including the radiotherapy alone group (CF) which received conventional conformal radiotherapy to a total of 60 - 66 Gy, LCAF group which received conventional fractionated conformal radiotherapy during the first two-thirds of the treatment to a dose about 40 Gy/20F/4W, then followed by late accelerated hyperfractionated conformal radiotherapy, twice daily radiotherapy at 1.3 Gy per fraction to a total dose about 64 - 69 Gy, and LCAF + C group (late accelerated hyperfractionated radiotherapy combined with capecitabine), in which patients were treated as the same as the LCAF group, except that they were treated with capecitabine (1.5 g po bid) from beginning of the radiotherapy to the end.

RESULTSThe short-term results of the 3 groups were 74.0%, 85.5% and 95.2%, respectively (P = 0.006). The local control rates at 1, 3 and 5 years were 64.0%, 30.0%, 24.0% in the CF group, 81.8%, 65.5%, 58.2% in the LCAF group and 90.1%, 77.8%, 74.6% in the LCAF+C group, respectively. The 1-, 3- and 5-year survival rates of the 3 groups were 58.0%, 20.0%, 8.0%; 78.2%, 36.4%, 17.0% and 85.7%, 55.6%, 30.2%, respectively. The effect of LCAF+C group was better than that of LCAF group and CF group. The incidence of acute tracheitis and acute esophagitis in the LCAF+C group and LCAF group was higher than that in the CF group, but there was no stastistically significant difference between the 2 groups. There was no statistically significant difference in distant metastasis in the 3 groups.

CONCLUSIONSCapecitabine, as an effective chemosensitizater combined with late accelerate hyperfractionated radiotherapy can improve the short-term results of treatment of esophageal cancer. The value of this combined treatment in distant metastasis reqires further study in the clinic.
