In recent years, many studies showed that its pharmacological activities of anti-tumor, heart function improvement, nerve protection and antiasthma depended on its inhibition of matrix metalloproteinase ( MMPs) . In the present paper,the new pharmacological actions of doxycycline were reviewed to promote the applications in clinics.

Objective To investigate the infectious rates of 9 common pathogens and epidemiology in children with acute respira‐tory tract infections(ARI) in Maoming district .Methods The serum were collected from 6 241 children with acute respiratory in‐fection .IgM of 9 common pathogen including Mycoplasma pneumoniae (MP) ,Legionella pneumophila (LP) ,Coxiella burnetii (C .burnetii) ,Chlamydophila pneumoniae(CP) ,adenovirus(ADV) ,respiratory syncytial virus(RSV) ,type A and type B influenza virus(INFA and INFB) ,and parainfluenza virus(PIVS) ,were detected using immunofluorescence assay .Results Among 6 241 ca‐ses ,1 320 showed atypical pathogens infection ,and infection rate was 21% .The positive rate of MP was 15 .12% ,the highest infec‐tious pathogen;followed by the positive rate of INFB ,LP ,ADV and PIVS were 3 .03% ,1 .92% ,0 .54% and 0 .22% respectively . The pathogens with the lowest positive rate were RSV ,COX ,INFA and CP ,their infectious rates were 0 .14% ,0 .11% ,0 .048%and 0 .016% respectively .Conclusion The infection rate of atypical pathogen among children is high in this area ,which should be taken seriously .MP is the most common pathogen in children with ARI in Maoming district .The pathogen positive rate has rela‐tionship with season .

We evaluated the differential expression and function of chitinase 3‐like‐1 in macrophage stimulated by Sporothrix schenckii and Candida albicans fungicidal ability of macrophage after stimulation with Sporothrix schenckii and Candida albi‐cans separately was detected .The expression of CHI3L1 gene in macrophage stimulated by Sporothrix Schenckii and Candida albicans was evaluated with real‐time PCR .The function of CHI3L1 protein in macrophages against the reproduction of Sporo‐thrix schenckii and Candida albicans was detected in vitro .Results showed that macrophages could engulf and kill Sporothrix Schenckii and Candida albicans in vitro .The expression of CHI3L1 gene in macrophage stimulated by Candida albicans was increased obviously .At the same time ,CHI3L1 protein can damper the reproduction of Candida albicans .However ,the ex‐pression of CHI3L1 gene was not elevated when macrophage was stimulated by Sporothrix schenckii and CHI3L1 protein played little role in reproduction of Sporothrix schenckii .The expression of CHI3L1 gene in macrophage was elevated after stimulation with Candida albicans ,but was not elevated with Sporothrix Schenckii .In correspondence with differential ex‐pression ,CHI3L1 in macrophages could impair the reproduction of Candida albicans but had a weak function on Sporothrix schenckii which might contribute to the pathogenesis of spo‐rotricosis .

Objective To explore the expressions of Toll-like receptors (TLRs) 2 and 4 in mouse skin during early immune responses against Sporothrix.Methods A total of 60 BALB/c mice were randomly and equally divided into an experimental group and a control group to be intracutaneously injected with Sporothrix conidium suspensions at a concentration of 1 × 106 cfu/ml and sodium chloride physiological solution respectively.Five mice were sacrificed before the injection,and at 6,12,24,48,and 96 hours after the injection in each group,blood samples were obtained from the mice before sacrifice,and skin tissue specimens were resected from the area around the injection sites after sacrifice.Realtime fluorescence-based quantitative PCR was performed to quantify the mRNA expressions of TLR2 and TLR4,and immunohistochemical staining to observe the protein expressions of TLR2 and TLR4 in mouse skin specimens.Enzymelinked immunosorbent assay (ELISA) was conducted to determine the levels of interleukin 12 (IL-12) and tumor necrosis factor α (TNFα) in serum samples from the mice.Results After injection of Sporothrix conidium suspensions,the mRNA expression level of TLR2 gradually increased and peaked at 24 hours,which was 18.8 times that in the control group at 6 hours and 34 times at 24 hours.In addition,the mRNA expression level of TLR4 in the experiment group reached a peak,and was 56.7 times that in the control group at 6 hours after injection,then gradually decreased and reached the nadir at 96 hours.As immunohistochemical staining revealed,TLR2 and TLR4 were apparently expressed in both keratinocytes and macrophages in skin specimens from the experimental group,but not obviously in those from the control group.No significant differences were observed between the experimental group and control group in serum levels of IL-12 or TNF-α at any of the sampling time points.Conclusion TLR2 and TLR4 may play a favoring role in immunological defense by participating in the recognition of Sporothrix by keratinocytes and macrophages in mouse skin.

Objective To investigate the expression pattern and significance of two importantoocyte-secreted factors:growth differentiation factor 9(GDF9)and bone morphogenetic protein 15(BMP15)during oocyte maturation in women with polycystic ovary syndrome(PCOS)and infertile women due to husband factors.Methods Total of 25 oocytes[9 at germinal vesicle GV stage,9 at M Ⅰ stage and 7 at M Ⅱ stage]were obtained from 12 patients with PCOS and 82 oocytes(29 at GV stage,26 at M Ⅰ stage and 27 at M Ⅱ stage)were from 56 controls.The nested quantitative real time(RT)PCR was uscd to detect the abundance of GDF9 and BMP15 mRNA in each oocyte.Results(1)The expression level of GDF9 mRNA at the GV stage,M Ⅰ stage and M Ⅱ stage in PCOS group were 44.8(4.2-529.0),27.6(9.8-172.7)and 49.0(0.2-65.9)respectively,the expression in were 149.9(55.4-387.9),29.9(2.5-205.8)and 657.8(149.4-1376.2)in control group,respectively.The expression of GDF9 mRNA at M Ⅱ stage was significantly lower in PCOS group than in controls(P ＜ 0.01),however,the differences didn't reach statistical significant at GV or M Ⅰ stage between the two groups(P ＞ 0.05).The expression of GDF9 mRNA displayed some changes at different maturation stage in controls(P ＜ 0.05,P ＜ 0.01),however,the expression didn't demonstrate any dynamic changes in PCOS group(P ＞ 0.05).(2)The expression level BMP15 mRNA at the GV stage,M Ⅰ stage and M Ⅱ stage in PCOS group were 0.1(0.1-22.0),3.2(0.6-55.0)and 6.4(3.2-8.5),respectively,the expression were 41.6(6.5-96.1),4.0(2.0-10.4)and 49.7(2.3-139.5)in control group,respectively.The expression of BMP15 mRNA at GV stage was significantly lower in PCOS group than in controls(P ＜ 0.01),however,the differences were not significant at M Ⅰ or M Ⅱ stage between the two groups(P ＞0.05).The expression of BMP15 mRNA also displayed some changes at different maturation stage in controls(P ＜ 0.05),however,the level didn't demonstrate any dynamic changes in PCOS group(P ＞ 0.05).Conclusion It was suggested that the low expression of oocyte secreted factors in mature oocytes from PCOS patients might be associated with impaired oocyte quality and developmental competence in PCOS.

Objective: To investigate the clinical features and prognosis factors of acquired immunodeficiency syndrome (AIDS) patients complicated with cryptococcal meningitis (CM). Methods: Retrospective analyses were performed on clinical features, laboratory data, treatment status and related prognosis factors in 81 AIDS patients with CM admitted to the Department of Infectious Diseases, Beijing You′an Hospital, Capital Medical University from January 2010 to December 2017. The t test, rank sum test and χ² test were employed to analyze the data. Results: Of the 81 AIDS patients with CM, 71 cases were infected with human immunodeficiency virus (HIV) by sexual transmission (87.7%). The most common clinical symptoms were fever in 60 (74.1%), headache in 72 (88.9%), and nausea and vomiting in 56 (69.1%). Cerebrospinal fluid (CSF) examination results show that 60 cases (74.1%) had elevated opening pressure, the white blood cell count was 17.0 (6.0, 44.5)×10⁶/L, monocyte count was 9.0 (3.0, 29.5)×10⁶/L, the level of chloride was (117.26±5.61) mmol/L, of glucose was 2.89 (2.05, 3.41) mmol/L, of protein was 0.32 (0.21, 0.65) g/L, ink staining positive rate was 84.0% (68/81), fungal culture positive rate was 59.3% (48/81). The positive rate of serum cryptococcal antigen was 96.3% (78/81), and CSF cryptococcal antigen positive rate was 93.8% (76/81). The clinical efficacies were not significant different among different treatment regimens (χ²=1.479, P=0.533). After treatment, 60 patients survived and 21 died, with an overall mortality rate of 25.9%. Univariate analysis showed that consciousness disorder and CSF opening pressure were significantly higher in the death group than those in the survival group (χ²=22.365, t=0.317, respectively, both P<0.05), while serum albumin (Alb) and CD4⁺ T lymphocyte counts were significantly lower in the death group than those in the survival group (t=7.975, Z=-3.073, respectively, both P<0.05). Multivariate logistic regression analysis showed that consciousness disorder and Alb were independent factors influencing the clinical outcome of AIDS patients with CM. Consciousness disorder was related with poor outcome (odd ratio (OR)=26.704, P=0.011, 95% confidence interval (CI) 2.115-337.247), and higher Alb was related with good outcome (OR=0.671, P=0.005, 95%CI 0.507-0.888). The area under the receiver operating characteristic curve of serum Alb for predicting poor outcomes of AIDS patients with CM was 0.932 (95% CI 0.859-0.998, P<0.01). By using 31.7 g/L as cut-off value, the sensitivity was 95% and the specificity was 81% for predicting poor outcome. Conclusions AIDS complicated with CM has a high mortality rate, and its clinical features are lack of specificity. Consciousness disorder and Alb are independent prognosis factors.
