Aspergillus tracheobronchitis is the generic term for all the diseases caused by planting and growing of Aspergillus in the airway, mainly including invasive Aspergillus tracheobronchitis, ulcerative Aspergillus tracheobronchitis, pseudomembranous necrotizing Aspergillus tracheobronchitis and tracheobronchial aspergilloma. Aspergillus tracheobronchitis is frequently seen in populations with immunodeficiency accompanied with local airway damages. This article reviews the pathogenesis, clinical symptoms, imagining findings, diagnosis, treatment and prognosis of the disease, and the clinical features of populations with impaired general immune function.

Objective To understand the effect of circumcision in reducing high-risk human papilloma virus (HPV) infection in male adults. Methods One hundred and twenty-eight married adults with phimosis who underwent circumcision enrolled in the case group and high-risk HPV of urethral discharge specimens were detected before and 2 years after operation. A total of 128 cases of phimosis without circumcision were recruited in the control group. High-risk HPV infection rates were compared between the two groups. Results The highrisk HPV infection rates in the two groups were comparable at baseline. In the circumcision group, high-risk HPV infection rate was 27. 3% preoperative and it significantly decreased to 12.5% two years after operation( x2 =8. 839 ,P =0. 005). In the control group,high risk HPV infection rate was 28. 1% at baseline and it was 25.0%two years later, with no significant difference (x2 =0.320,P = 0.671).Conclusion Circumcision can significantly reduce high-risk HPV infection. Promoting circumcision actively in our country may have an important role in preventing high-risk HPV infection.

Hepatic fibrosis models were induced by CCl4 in rats. To explore vascular endothelial growth factor (VEGF), transforming growth factor-beta1 (TGFβ1) mRNA expression and bcl-2, Bax protein expression levels of intervention and explore the mechanism of the Aralia chinesis anti-hepatic fibrosis. Sixty male Sprague-Dawlley (SD) rats were randomly divided into six groups: nomal group, model group, high-dose (10 mL x kg(-1)), medium-dose (7.5 mL x kg(-1)), low-dose (5.0 mL x kg(-1)) of A. chinesis treated group and colchicine treated group. The change of liver histopathology was observed by HE and Masson staining. The mRNA of VEGF, TGF-β1 were detected by RT-PCR. The protein of Bcl-2 and Bax were detected by Western blot. In the model group liver cell obvious degeneration, necrosis, a large number of collagen fibers of the cable hyperplasia, part visible pseudolobule formation. A. chinesis large, medium, low-dose group and colchicine group liver cell degeneration and necrosis reduced A. chinesis small, medium, and high-dose group was gradually reduced trend and A. chinesis large, middle dose group degree of reduction is particularly significant. Compared with model group, A. chinesis of large, medium and small dose group and colchicine group VEGF mRNA expression, A. chinesis of large, medium-dose group TGF-β1 mRNA expression reduce (P < 0.05); compared with colchicine group, A. chinesis of large, middle dose group of VEGF mRNA expression decreased (P < 0.05); A. chinesis of large, middle dose group of TGF-β1 mRNA expression decreased (P < 0.01), and compared with colchicine group, large dose group of of TGF-β1 mRNA expression decreased (P < 0.05). Compared with model group, A. chinesis of large, medium and small dose group and colchicine group Bcl-2 protein expression reduce (all is P < 0.05). But A. chinesis of large, medium and small dose group and colchicine group of Bax protein expression were increased (P < 0.05). A. chinesis regulation of VEGF, TGF-β1 may prevent the activation of hepatic stellate cells, liver tissue by up regulating the anti-apoptotic protein Bax and down pro-apoptotic protein Bcl-2 expression, thereby to improve the degree of liver fibrosis.

Trachoma, a contagious keratoconjunctivitis ( KC ) , caused by Chlamydia trachomatis infection, is rife in 57 countries in the world at present. The World Health Organization ( WHO) listed the global alliance to eliminate blinding trachoma by 2020 as one of top priorities of its blindness prevention in 1998. A simplified classification system for identifying and naming trachoma, designated by WHO, and the SAFE strategy based on community intervention were extended continuously in the world in 10 years since then. The trachoma prevalence trend has showed a change compared with that in the past. China has launched the blindness prevention action, aimed to eliminate blinding trachoma by 2016. In this paper, we reviews progress in diagnosis, treatment and epidemic of trachoma since the extension of the SAFE strategy.

Objective To investigate the influence of body temperature on the recovery from vecuronium-induced neuromuscular block.Methods Sixty-eight ASA I - II patients (39 male, 29 female) aged 19-69 yr undergoing elective surgery under general anesthesia were randomly divided into 2 groups: group I in which patients' body temperature was maintained at 37 ℃ using warming blanket; group II in which no measures were taken to maintain the patients' body temperature. The patients were premedicated with phenobarbital 2 mg?kg-1 and atropine 0.01 mg? kg-1 intramuscularly. Anesthesia was induced with fentanyl 5 ?g? kg -1, propofol 2 mg? kg-1 and vecuronium 0. 1 mg?kg-1 . After tracheal intubation anesthesia was maintained with inhalation of 0.8%-2.5% isoflurane and propofol infusion at a rate of 2-4 mg ? kg-1? h-1 .Neuromuscular block was monitored using accelograph (Biometer, Denmark) .The changes in TOF and T1 were monitored. T1was maintained at 10% by vecuronium infusion during operation. At the end of operation a bolus of vecuronium 80?g ? kg-1 was given intravenously and T1 was completely depressed. The time for T1 to returned to 5% ,25% and 90% and the time required for T1 to return from 25 % to 75 % were recorded. The total amount of vecuronium given was recorded. Temperature probe was placed in the esophagus ( core temperature) . The room temperature was also recorded. Results The body temperature was lower, the total dose of vecuronium was smaller and the vecuronium-induced neuromuscular block lasted longer in group II as compared with group I . There was close correlation between body temperature and vecuronium-induced neuromuscular block. Conclusions Lower core body temperature could prolong the vecuronium-induced neuromuscular block.

Objective To observe the expression of YKL-40 protein in the pulmonary tissues of rats with bleomycin-induced pulmonary fibrosis (PF). Methods The PF model group was induced with intratracheal instillation of bleomycin solution (7. 5 mg/kg) and the control group was treated with normal saline. On day 7, 14, 21 after bleomycin challenge, rats were sacrificed and the pulmonary tissues were harvested. H-E staining, Masson staining and Szapiel score were employed to determine alveolitis and pulmonary fibrosis. Expressions of YKL-40 in lung tissues were detected by real-time RT-PCR, Western blotting analysis and immunohistochemistry method. Results Bleomycin instillation induced alveolitis in the lung of rats, with inflammation score being significantly higher on day 7 (2. 8 ± 0. 45, P<0. 01) and on day 21 (1. 8 ± 0. 84, P<0. 05) compared with that of control group (0. 42± 0. 25). Pulmonary fibrosis degrees in model group was significantly higher on day 14 (1.7 ± 0.73, P<0.05) and on day 21 (2.9± 0.56, P<0. 01) compared with that of control group (0.2 ± 0.45). YKL-40 mRNA (YKL-40/p-actin) expression was significantly increased on day 7 (3. 71 ± 0. 25) after bleomycin treatment compared with the control group (P<0. 05). Western blotting analysis showed that YKL-40 protein expression was significantly increased on day 14(0. 56 ±+ 0. 24,P<0. 05) and on day 21(1. 15 ± 0. 19, P<0. 01) after bleomycin treatment compared with the control group (0. 23 ± 0. 07). The results of immunohistochemistry showed that bleomycin up-regulated YKL-40 expression in a time-dependent manner, and YKL-40 expression was mainly located in the smooth muscle cells, alveolar macrophages, alveolar epithelium and fibroblasts. Conclusion YKL-40 expression may contribute to the pulmonary fibrosis, and may participate in the pathogenesis of pulmonary fibrosis.
