Objective To investigate the expression of excision repair cross-complementation group 1 (ERCC1) and ribonucleotide reductase subunit M1 (RRM1) in patients with esophageal squamous cell carcinoma,and the relationship between the expression of ERCC1 and RRM1 genes and chemotherapy sensitivity.Methods A total of 77 patients with esophageal squamous cell carcinoma admitted in hospital from Jan.2008 to Dec.2012 were recruited.ERCC1 and RRM1 mRNA levels in the cancerous tissue were detected by real-time fluorescent quantitative RT PCR.The relationship between short-term effects of chemotherapy and ERCC1 and RRM1 mRNA levels was analyzed.Results Levels of mRNA in stages Ⅰ a,Ⅰ b,Ⅱ a,and Ⅱ b were (0.578±0.081),(0.560±0.084),(0.521±0.080),(0.464±0.091) for ERCC1 and(0.511±0.089),(0.539± 0.086),(0.584±0.092),(0.637±0.101)for RRM1,respectively.As the clinical stage advanced,the ERCC1 mRNA level declined and the RRM1 mRNA level increased (t=2.679 and 2.952,P =0.034 and 0.025,respectively).Levels of mRNA in patients with complete remission,partial remission,stable disease and progressive disease were (0.487 ± 0.097,0.511 ± 0.095,0.552 ± 0.086,0.568 ± 0.088) for ERCC1 and(0.504±0.091,0.544±0.095,0.595±0.093,0.616±0.097) for RRM1,respectively.The clinical effect of chemotherapy was negatively correlated with mRNA expression of ERCC1 and RRM1 (r=0.567,P=0.032).Conclusions Levels of ERCC1 and RRM1 mRNA expression are correlated with the staging of esophageal squamous cell carcinoma and chemotherapy sensitivity,and can be used as a predictive parameter for chemotherapy sensitivity in patients with esophageal squamous cell carcinoma.

Objective To investigate the affecting factors of interventricular septum (IVS) swing by study of the mechanical model of the respiration-driven variation of cardiac function using echocardiography.Methods In present study,the equivalent mechanical model of septal swing in previous study was used.By changing the end-diastolic pressure difference between the simulated right and left ventricles and simulated intrapericardial pressure,the subsequent influences on IVS swing using echocardiography were observed.Results Under the rhythmic respiratory intrathoracic pressure change(RIPC)(0--4 mm Hg,1 mm Hg =0.133 kPa),the swing amplitude of simulated IVS increased with decrease of the simulated end-diastolic pressure difference between the simulated right and left ventricles (2.2-17.6 mm).With increasing of the simulated intrapericardial pressure,the simulated right ventricle and left ventricle collapsed in succession,the swing amplitude of simulated IVS also increased to a maximal amplitude of 22.4 mm.Conclusions The affecting factors of IVS swing including the magnitude of RIPC,the end-diastolic pressure difference between the two ventricles and the intrapericardial pressure.

This article explores the possible influencing factor and regular pattern of temperature rise induced by photo-thermal effect of gold nanorods when irradiated with near infrared region (NIR) laser. We used transmission electron microscope and UV-Vis-NIR spectrometer to characterize gold nanorods, then used 808 nm NIR laser with different power to irradiate the gold nanorods in different conditions and measured the temperature of the above solution. The higher the concentration of gold nanorods, the faster the temperature rose and the bigger its amplitude was. When the concentration of gold nanorods was fixed, the relation between power of laser and amplitude of temperature rise was linear. Temperature rise was also related to the shape of container. It could be concluded that amplitude of temperature rise of gold nanorods reaction system was related with concentration of the particles, irradiated power and shape of the container, so that we could control the temperature easily by regulating the irradiated power size of NIR laser in the experiments.

Objective To observe the changes of tear film stability,goblet cell and mucin 5AC expression in conjunctivochalasis patients,and explore the mechanism of conjunctivochalasis.Methods Conjunctivochalasis patients (30 cases) and single age-related cataract patients (15 cases) were collected as conjunctivochalasis group and normal control group.Eye symptom assessment (OSDI score),tear break-up time (BUT),Schirmer Ⅰ test,tear fern crystallization tests were performed for all the selected persons.Conjunctival rescent-shaped resections were made for all the conjunctivochalasis patients.Conjunctival tissue samples were stained by HE staining,AB staining,mucin 5AC immunohistochemical staining from the conjunctivochalasis group and norral control group respectively,and then statistical analysis was made.Results The OSDI score in the conjunctivochalasis group (37.80 ± 8.94) was significantly higher than that in the normal control group (11.40 ±4.08) (P ＜0.01).BUT in the conjunctivochalasis group (6.70 ± 2.76) s was significantly lower than that in the normal control group (13.67 ± 3.48) s (P ＜ 0.01).Schirmer Ⅰ test in the conjunctivochalasis group (6.23 ± 3.13) mum was significantly lower than the normal control group (13.40 ± 3.74)mm (P ＜ 0.01).Tear ferbing crystallization of the conjunctivochalasis group was decreased significantly compared with the normal control group (x2 =14.309,P =0.003).Light microscopic showed that conjunctival thickness was thinned,collagen fibers were less,elastic fiber was reduced,the lamina propria and interstitial were congestion and edema,the number of goblet cells was significantly reduced,and the positive staining of mucin 5AC staining was significantly lower in the conjunctivochalasis group than in normal control group (x2 =9.499,P =0.023).Conclusion For patients with conjunctivochalasis,the tear film function is affected,goblet cells are decreased,tear fern crystallization is decreased,mucin 5AC content is decreased,which finally leads the excessive conjunctival relaxation and abnormal ocular surface and tear.

Objective To explore the significance of interleukin (IL)-1β and IL-6 in serum of children with hyperuricemia (HUA). Methods 142 children including 71 children with HUA (HUA group) and 71 control children (control group), healthy and inguinal hernia children were selected as control group. 71 HUA children were subdivided into GA (gout attacks) group (n=28) and NGA (non-gout attacks) group (n=43) according to whether they had a history of acute gout attacks, including sudden monoarthritis of rapid onset with intense pain and swelling or without. Enzyme-linked immunosorbent assay was used to measure the level of IL-1β and IL-6 in serum. Results Serum IL-1β and IL-6 levels of HUA children were significantly higher than those of control group (all P<0.05). Serum IL-1β and IL-6 levels of HUA children in GA group were significantly higher than those of NGA group (P<0.05). Serum IL-1β and IL-6 levels of GA group in acute phase was significantly higher than those of HUA children in remission stage、NGA group and control group (P<0.05). Serum IL-1β and IL-6 levels of GA group in remission stage and NGA group was significantly higher than those of control group (P<0.05). There were no significant differences between HUA children in remission stage and NGA group (P>0.05). The serum IL-1β and IL-6 levels of HUA children were positively correlated with WBC, neutrophils, monocytes, uric acid, ESR, CRP, BUN and Cr (all P<0.05), while not correlated with triglyceride, total cholesterol, LDL-C and HDL-C(all P<0.05). Conclusion IL-1β and IL-6 play an important role in the pathogenesis of HUA in children.

Objective To research the pathogen characteristics and influencing factors for peritonsillar peripheral space infections in acute tonsillitis patients,so as to take measure to reduce the peritonsillar peripheral space infections.Methods 898 acute tonsillitis patients who received treatment were chosen as study subjects.Bacteria analyzer was adopted to identify pathogens.Chi-square test was used to analyze the univariate factor,and logistic regression analysis was conducted to different factors.Results 228 patients were involved the complications of peritonsillar peripheral space infections(cellulitis in 52 cases or abscesses in 176 cases),and the infection rate was 25.4％.Bacterial cultivation performed in 177 patients and positive results were detected in 107.The top three infections bacteria were Staphylococcus aureus (21.5％),Streptococcus viridians (19.6％) and Klebsiella pneumoniae (15.9％).Univariate factor analysis found that the history diabetes and peritonsillar peripheral space infections,age,acute phase of smoking and drinking,fatigue,nutritional status,class of antibiotic use,tonsillitis type,educational level and the long first diagnosis time were risk factors for peritonsillar peripheral space infections,and the differences were significant (x2 =39.851,8.818,89.041,87.266,30.417,21.499,13.472,64.548,12.223,62.871,70.749,all P ＜ 0.05).Logistic regression analysis found that acute phase of smoking and drinking,age,fatigue,tonsillitis type and the long first diagnosis time were independent risk factors for peritonsillar peripheral space infections patients with acute tonsillitis (OR =2.873,5.311,5.876,0.290,2.244,2.369,all P ＜ 0.05).Nutritional status and educational level had beneficial effect to peritonsillar infections event (OR =0.290,0.461,all P ＜ 0.05).Conclusion Acute tonsillitis is easy to cause peritonsillar peripheral space infection,it should be paid much attention and strengthened prevention.The pathogens causing peritonsillar peripheral space infections in acute tonsillitis is still mainly Staphylococcus aureus.After the analysis of related factors,the certain measures should be taken to reduce the complications rate of peritonsillar peripheral space infections in acute tonsillitis.

Objective Pressure Ulcer Scale for Healing ( PUSH) was published in 1998 by National Pressure Ulcer Advisory Panel ( NPUAP) as a tool to evaluate the effects of pressure ulcer care.This study aimed to verify the reliability and validity of the Chi-nese version of PUSH in order to provide an efficient and reliable tool for evaluating the effects of pressure ulcer care. Methods Using the Brislin translation model, we translated the English version of PUSH into Chinese and finalized the Chinese version through modifica-tion by an advisory panel, pretests, and verification of its reliability and validity in the care of 126 cases of stage-Ⅱ-Ⅳpressure ulcers. We analyzed the reliability and validity of the scale based on its item scores, content validity, construct validity, Cronbach′s αcoeffi-cient, and test-retest reliability. Results The correlation coefficient value of the total and individual item scores was 0.616-0.963 (P<0.01).Each individual item score was significantly higher in the 27%high-score group (n=35) than in the 27%low-score group (n=36).The total content validity coefficient was 0.965, the correlation coefficient of construct validity between the total and individual item scores was 0.750-0.954 (P<0.01), and that between individual items was 0.666-0.826 (P<0.01), with statistically signifi-cant differences between the total and individual item scores at 7 and 21 days after treatment (P<0.01).The Cronbach′s αreliability coefficient value of the total score was 0.823 and those of individual item scores were 0.770, 0.791, and 0.868, respectively.The inter-rater reliability coefficients were all >0.85 and the test-retest reliabili-ty coefficients of individual items were 0.826, 0.885, and 0.958, re-spectively ( P<0.01) . Conclusion The Chinese version of PUSH, with its high validity and reliability, can be used to evaluate interven-tion effectiveness of Chinese patients with pressure ulcers.
