Objective To analyze the risk factors of subclavian venous catheter-related infections in patients with traumatic hemorrhagic shock (THS) and provide a basis for prevention and control of the infection. Methods A retrospective study was conducted. 357 patients with THS and indwelling of subclavian vein catheter admitted in the Department of Emergency of Affiliated Hospital of Sichuan Provincial Luzhou Medical College were enrolled, and according to the infection state, they were divided into infection group (56 cases) and non-infection group (301 cases). The patients' data of gender, age, history of underlying disease, catheter position, catheter indwelling time, time staying in hospital, situation of antimicrobial drug used, application of tracheotomy or not, white blood cell count (WBC) levels, etc were collected for univariate analysis. The resulting indexes with statistical significance were applied for carrying out the multivariate logistic regression analysis, and then the independent risk factors involved in the development of subclavian venous catheter-related infections in the shock patients could be screened out.Results In 357 patients with THS, 56 were infected (15.7%). Univariate analysis showed: age ≥ 60 years (χ2 = 19.839,P < 0.001), with diabetes mellitus in past history (χ2 = 6.252,P = 0.012), catheter indwelling time ≥ 7 days (χ2 = 19.261,P < 0.001), time staying in hospital ≥ 7 days (χ2 = 4.315,P = 0.038), time for use of antimicrobial drug≥ 7 days (χ2 = 16.161,P < 0.001), tracheotomy (χ2 = 40.969,P < 0.001), WBC < 4×109/L (χ2 = 39.451,P < 0.001) and the disease severity grade 4 - 5 (χ2 = 8.345,P = 0.004) were the risk factors of subclavian venous catheter-related infections in patients with THS. Multivariate analysis showed: catheter indwelling time ≥ 7 day [odds ratio (OR) = 16.713, 95% confidence interval (95%CI) 3.651 - 76.624), tracheotomy (OR = 6.861, 95%CI 2.377 - 18.246), WBC < 4×109/L (OR = 4.903, 95%CI 1.887 - 12.643) were the independent risk factors of subclavian venous catheter-related infections in THS patients.Conclusion The strict implementation of aseptic catheterization, shortening the time of catheter indwelling as much as possible and the rational use of antibiotics can effectively reduce and prevent the incidence of venous catheter-related infection in THS patients.

OBJECTIVETo investigate the impact of in utero exposure to di-n-butyl phthalate (DBP) on the apoptosis of testicular cells in the pubertal male rat offspring.
METHODSTen pregnant SD rats were randomly divided into a control and an experimental group to be treated intragastrically with olive oil (1 ml per day) and DBP (500 mg per kg of body weight per day) respectively between gestation days 12 and 19. At the pubertal age (postnatal day 45, PND 45), the testes of the male rat offspring were removed for observation of the cell structure under the transmission electron microscope and the development of different spermatogenetic cells by HE staining. The apoptosis of testicular cells was detected by the TUNEL method, the expressions of the apoptosis-regulating proteins Bcl-2, Bcl-XL, Bax and p53 were determined by immunohistochemistry and Western blot, and the data obtained were compared between the two groups by t-test.
RESULTSTransmission electron microscopy revealed increased apoptosis and vacuolization of testicular cells in the PND-45 rat offspring, HE staining showed markedly decreased numbers of different spermatogenetic cells, TUNEL manifested significantly increased apoptosis of testicular cells in the experimental group as compared with the control (12.00 ± 5. 22 vs 3.17 ± 1.47, P < 0.01), and immunohistochemistry and Western blot exhibited remarkably higher expressions of Bax and p53 in the former than in the latter group (P < 0.05).
CONCLUSIONIn utero exposure to DBP can increase the apoptosis of germ cells and Sertoli cells, induce the vacuolization of testicular cells, and significantly elevate the expressions of the apoptosis-promoting proteins Bax and p53 in the pubertal male rat offspring.

OBJECTIVE:
To compare the symptoms and lower airway inflammatory factors of patients with allergic rhinitis (AR), and to observe the effect of nasal irrigation in the treatment of allergic rhinitis.
METHOD:
Sixty-one cases diagnosed as AR after skin prick test (SPT)were selected and randomly divided into three groups: 17 patients in group A used nasal steroid spray; 21 cases in group B used nasal irrigation; 23 patients in group C combined ir rigation with nasal steroid. Before and after 3 months treatment, nasal visual analogue scale (VAS) score, rhino conjunctivtis quality of life questionnaire (RQLQ) score, fractional exhaled nitric oxide (FENO) values were observed and compared in each group.
RESULT:
Before treatment, there is no statistically difference between three groups (P > 0.05). After 3 months of treatment, VAS, RQLQ, FENO of all patients was significantly decreased (P < 0.05); VAS, RQLQ score was not significantly different among the three groups (P > 0.05), FENO value has no statistically significant difference between group A and group B (P > 0.05), but were less than that in group C (P < 0.05).
CONCLUSION
Nasal irrigation can ameliorate nasal symptoms, improve quality of life, decrease lower airway inflammation of allergic rhinitis patients. Nasal irrigation is an effective treatment of allergic rhinitis. Nasal irrigation combined with nasal steroid can achieve more significant efficacy.

Background and purpose:Head and neck cancer is common worldwide. This article aimed to describe the patterns of incidence of head and neck cancer and their changes in Shanghai from 2003 to 2012, in order to provide reference for prevention programs, research and control strategies on cancer.Methods:The data of lip, oral cavity and pharynx cancer cases were collected by the Shanghai Cancer Registry. The distributions of Shanghai lip, oral cavity and pharynx cancer incidences from 2003 to 2012 were described. The patterns were described according to gender, age, basis of diagnosis, histological type, diagnostic stage in detail. We compared incidences of recent 5 years (from 2008 to 2012) with those of previous 5 years (from 2003 to 2007).Results:On average from 2003 to 2012, 1105 new cases of head and neck cancer were diagnosed in Shanghai each year, with 2.08% among the total cancer cases. The crude rate was 8.01 per 100000 and the age-standardized rate was 4.45 per 100000. Nasopharyngeal cancer was the major subtype of the head and neck cancer, with 50.81% among the total head and neck cases. The crude and age-standardized rates among males were higher than those among females. The histologically verified percentage was 85.77%. The squamous carcinoma was the major histological type, with 57.58% among the total cases. The age-stan-dardized rate of nasopharyngeal cancer was in decline.Conclusion:The incidence of head and neck cancer was low in Shanghai during the past 10 years. Male cases were more than female cases. The major histological type was squamous carcinoma. Half of new cases were nasopharyngeal cancer which appeared to affect patients at a relatively young age. Patients with nasopharyngeal cancer were diagnosed at relatively advanced stages.

In this paper, we studied the relationship between the prostaglandin F(2alpha) (PGF(2alpha))-induced cardiac hypertrophy and calcineurin (CaN) signal transduction pathway in vivo and in vitro. Male Sprague-Dawley rats were given a single i.p. injection with monocrotaline (MCT) (60 mg/kg) and then given orally with celecoxib (20 mg/kg) or vehicle once a day for 14 d before (from d 1 to d 14) or after (from d 15 to d 28) right ventricular hypertrophy (RVH) was formed. Body weight (BW), right ventricular weight (RV), left ventricular with septum weight (LV), as well as lung weight were determined. RVH index (RVHI=RV/LV), RV/BW, and lung weight/BW were calculated and histological changes were observed with transmission electron microscope. PGF(2alpha) level, atrial natriuretic peptide (ANP) and CaN mRNA expressions, expression of CaN and its downstream effectors, NFAT(3) and GATA(4) protein were assayed by EIA kit, RT-PCR, and Western blotting, respectively. The cardiomyocyte hypertrophy in primary culture induced by PGF(2alpha) (0.1 micromol/L) was evaluated by measuring the cell diameter, protein content, and ANP mRNA as well as CaN mRNA expressions. It was found that 14 d or 28 d after MCT was given, the RVHI, RV/BW, and lung weight/BW were significantly increased by 47%, 53% and 118%, and by 64%, 94% and 156%, respectively; at the same time PGF(2alpha) levels in RV tissue were increased by 44% and by 51% with increasing RVHI, and elevated expressions of ANP and CaN mRNA, as well as CaN, NFAT(3) and GATA(4) proteins in a positive correlation manner. Furthermore, some histological injuries were found in RV tissue. Celecoxib, a cyclooxygenase inhibitor, obviously blunted the elevation of RVHI, RV/BW, and lung weight/BW no matter it was given before or after RVH. In vitro experiments showed that 0.1 micromol/L PGF(2alpha) significantly increased the cardiomyocyte diameter and protein content, and promoted ANP and CaN mRNA expressions, which was blocked by cyclosporin A, a CaN inhibitor. Our results indicate that PGF(2alpha) may be involved in cardiac hypertrophy induced by MCT in rats through CaN signal transduction pathway.
