OBJECTIVETo investigate the incidence of depression and its etiological factors in patients with cryptorchidism 6-16 years after surgical treatment.

METHODSUsing Self-Rating Depression Scale and Correlation Factor Questionnaire, we investigated the incidence of depression symptoms among 70 patients with cryptorchidism 6-16 years after surgical treatment and another 70 healthy males as controls, and analyzed the related factors of depression symptoms.

RESULTSThe incidence rate of depression symptoms was 50% in the cryptorchidism patients postoperatively, extremely significantly higher than 4.3% in the control group (χ2 = 23.5, P <0.01). Multiple stepwise regression analysis showed that the main risk factors of depression symptoms were worries about natural fertility (F = 15.8992, P <0.01), dissatisfaction with scrotal appearance (F = 4.6003, P <0.05), and the status of being married (F = 4.1002, P <0.05).

CONCLUSIONSymptoms of depression often occur in cryptorchidism patients after operation, and the major etiological factors are infertility, dissatisfaction with scrotal appearance, and the status of being married.

Objective To investigate the immunological mechanism of inhibitory effect of Danshen injection combined with dexamethasone(DXM) on asthmatic airway inflammation.Methods 50 Wistar rats were randomly divided into normal control(NC),asthma,Danshen,DXM and Danshen+DXM group.Cytology study of Bronchoalveolar lavage fluid(BALF) was conducted.Pathology of lung tissue was done through HE.Flow eytometry was used to detect CD4+CD25+ regulatory T Cells(CD4+CD25+ Treg) ratio in peripheral blood mononuclear cells(PBMCs).IL-4 and IL-5 levels in BALF were detected by ELISA.Results Total cells number,percentage of lymphocytes,neutrophils and eosinophils(Eos) in BALF of the three treated groups were lower than that in asthma group(P<0.05,P<0.01),particularly in Danshen+DXM group,which showed significant difference as compared with the other two treated groups(P<0.05).There was severe inflammation in lung tissue of asthma group,moderate inflammation in Danshen group and DXM group,and no inflammation of Danshen+DXM group.CD4+CD25+ Treg/CD4+ T ratio in the three treated groups were higher than that in asthma group,and the levels of IL-4 and IL-5 were lower than those in asthma group(P<0.05).In Dansben+DXM group,it showed significant difference on the change of CD4+CD25+ Treg,IL-4 and IL-5 as compared with other treated groups(P<0.05).Conclision Danshen injection combined with DXM could suppress airway inflammation in asthmatic rats,which may be through increasing the expression of CD4+CD25+ Treg,decreasing the levels of IL-4 and IL-5 and resuming the balance of Th1/Th2.

Objective To investigate dexamethasone on airway inflammation and CD4+ CD25 + regulatory T cells (CD4+ CD25 +Tr) of asthmatic rats,and elucidate the possible mechanism of dexamethasone in treatment of asthma.Methods 30 Wistar rats were randomly divided into control group,asthma group and dexamethasone-treated group.Bronchoalveolar lavage fluid (BALF) was collected,and cytology study was conducted.The lung tissue was obtained and pathologic analysis was done through HE stain.Flow eytometry was used to detect the CD4+ CD25 +Tr ratio in PBMCs.Results Total cells number,the percentage of lymphocytes,neutrophils and eosinophils (Eos)in BALF of dexamethasone-treated group were lower than that of asthma group (P＜0.05,P＜0.01).Compared with the asthma group,less infiltration of inflammatory cells in lung tissues was observed in the dexamethasone-treated group.CD4+ CD25 + Tr of asthma group was lower than that of control and dexamethasone-treated group (P＜0.05).Conclusion Dexamethasone could suppress airway inflammation of asthmatic rats,which probably be due to increasing the number of CD4+ CD25 + Tr.

Objective To discuss the safety of using etomidate combined with remifentanil by target controlled infusion ( TCI) for painless bronchofibroscopy. Methods Sixty patients were divided into two groups: painless bronchoscopy group (treatment group, 24 patients) and the routine bronchoscopy group (control group, 36 patients). Treatment group received TCI of remifentanil and intravenous injection of etomidate fat emulsion. Control group was subjected to surface anesthesia with 2%lidocaine. SpO2 , blood pressure, heart rate and breath changes during examination and complete awakening were continuously monitored. Bronchofiberscopy time, body movement during examination, bucking and satisfaction degree after examination were also recorded. Results Treatment group patients felt senseless and painless during bronchoscopy, without memory of bronchoscopy and pain. Patients in control group had discomfort, body movement and acute bucking, and most of them had painful memory. There were significant differences between the two groups (P<0. 01). In treatment group, after examination, blood pressure, respiratory frequency, heart rate and SpO2 were significantly decreased (P<0. 01). During examination, the blood pressure, respiratory frequency and heart rate were increased, and SpO2 decreased in control group compared to the baseline (P<0. 01). There was no significant difference in SpO2 between treatment group and control group during examination (P>0. 05). Conclusion TCI etomidate combined with remifentanil during bronchoscopy achieved satisfying anesthetic effect.

Objective To observe the possible mechanism and inhibitory effects of curcumin on pulmonary fibrosis induced bleomycin in rats at the fibrosing stage. Methods 80 male Sprague-Dawley rats were random divided into 4 groups (20 rats in each group). Rats in the fibrosis model group, the prednisone group and the curcumin group were induced by instilled bleomycin through tracheal, rats in the control group with same volume normal saline. Since the 15th day after bleomycin administration, the curcumin group and prednisone group were given curcumin (300 mg/kg) or prednisone (5mg/kg) per day by intragastric administration, respectively. The normal control group and the model group were given 1% sodium carboxymethyl cellulose ( 10ml/kg). Six rats of each group were random sacrificed on the 21st, 28th, 42nd and 56th days after bleomycin administration. The histological changes of the pulmonary were evaluated by H. E and Masson dyeing. The expressions of transforming growth factor-β1 (TGF-β1), platelet-derived growth factor (PDGF) and hydroxyproline in the tissue of pulmonary were assessed by immunohistochemistry and digestion method.
