Objective To investigate the current prevalence of depressive disorder and the associated factors in pa?tients with essential hypertensive from cardiovascular divisions of tertiary general hospitals. Methods A Chinese version of Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition) Axis I Disor?ders was conducted by five mental health professionals on 876 essential hypertensive outpatients at cardiovascular divi?sions of tertiary general hospital. Data on the socio-demographic and clinical characteristics of these hypertensive pa?tients were also collected. Results The current prevalence of depressive disorders among essential hypertensive outpa?tients of tertiary hospitals was 16.6%(145/876). Risk factors for depressive disorders in hypertensive patients included fe?male gender (OR=2.817, 95%CI:1.161~6.885), being 65-year-old and older (OR=1.747, 95%CI:1.118~2.688), non-marital status (OR=2.023, 95%CI:1.203~3.398), gradeⅢhypertension (OR=1.776, 95%CI:1.226~2.333) and car?diovascular diseases (OR=2.018, 95%CI:1.427~2.587). Conclusion Essential hypertensive outpatients, who receive med?ical services at cardiovascular divisions of tertiary general hospital, have high prevalence of depressive disorders. Clini?cians should pay more attention to the mental health of outpatients with essential hypertension.

OBJECTIVETo investigate the semen quality of cancer patients and search for a better way of sperm cryopreservation for them.

METHODSWe retrospectively analyzed the quality of the semen from 43 cancer patients under cryopreservation in the Sperm Bank of Zhejiang Province, and compared the semen parameters between the cancer patients and 248 normal donors as well as between the testicular cancer cases (n=22) and non-testicular cancer cases (n=21).

RESULTSThe cancer patients exhibited significantly lower semen quality than the normal donors as in sperm concentration (60.90 x 10(6)/ml vs 74.27 x 10(6)/ml), progressive motility (41.07% vs 51.79%), and recovery rate (49.98% vs 57.33%) (all P <0.05). Furthermore, the progressive sperm motility and sperm recovery rate after freezing were significantly decreased in the testicular cancer cases (15.68% and 42.81%) than in the non-testicular cancer cases (28.36% and 57.53%) (both P <0.05).

CONCLUSIONSemen quality declines in cancer patients, and therefore early sperm cryopreservation is essential for them. Due to the poor sperm motility and recovery rate of testicular cancer patients after freezing, further investigation is required on the improvement of sperm cryopreservation methods.

Objective To investigate the effect of selenium on proliferation and apoptosis of chondrocytes of articular cartilage cultured in vitro in Kaschin-Beck disease(KBD) patients and normal person, to explore the role of selenium in control of KBD, and to provide evidence for selenium's effect on the growth of normal cartilage cells. Methods The articular cartilage samples of grade Ⅱ and Ⅲ KBD patients were selected according to the national "Clinical Diagnosis of KBD" (GB 16003-1995). Chondrocytes of 5 KBD and 5 non-endemic normal accidentswere separated and cultured in vitro. KBD group and control group were given different doses of selenium (0,0.0125,0.0250,0.0500,0.1000,0.2500,0.5000,1.0000 mg/L, respectively). Methyl thiazolyl tetrazolium (MTT),flow cytometric analysis, and immunocytochemical staining were used to observe the effect of selenium on cell growth and apoptosis in KBD and normal persons. Results MTT results showed that the cell proliferation rate in each dosage group of the control group at the 6th day(0.086 ± 0.025,0.077 ± 0.012,0.073 ± 0.027,0.071 ± 0.017,0.058 ± 0.028,0.052 ± 0.028 and 0.046 ± 0.037) was significantly lower than that of 0 mg/L group(0.138 ± 0.026,all P ＜ 0.05);the average cell proliferation rate was negative( - 0.001 ± 0.001, - 0.003 ± 0.000, - 0.003 ± 0.001and - 0.004 ± 0.001 ) in 0.1000 - 1.0000 mg/L dose group, which was significantly lower than that of the 0 mg/L group(0.025 ± 0.003, all P ＜ 0.05);compared with 0 mg/L group(0. 115 ± 0.011), the KBD 0.2500 mg/L dose group promoted cell proliferation(0.128 ± 0.037, P ＜ 0.05), the KBD 1.0000 mg/L dose group inhibited cell growth (0.071 ± 0.019, P ＜ 0.05). The apoptotic rate of 0.0500 - 1.0000 mg/L dose control group [ (18.88 ± 0.02)%,(17.58 ± 0.01)%, (17.09 ± 0.04)%, (56.00 ± 0.02)%, (57.85 ± 0.03)% ] were higher than that of the 0 mg/L group[(13.51 ± 0.01)%, all P ＜ 0.05];compared with 0 mg/L group[(25.84 ± 0.02)%], the apoptotic rate in KBD 0.0250 - 0.2500 mg/L dose group [ ( 13.69 ± 0.02) %, ( 15.96 ± 0.03 ) %, ( 16.68 ± 0.03 ) %, ( 16.67 ± 0.02) % ]were lower, and the apoptotic rate in 0.5000, 1.0000 mg/L dose group [ (59.58 ± 0.03)%, (73.48 ± 0.04)% ] were significantly higher(all P ＜ 0.05). The Fas expression in KBD 0.0500 - 0.2500 mg/L dose groups[ (41.2 ± 1.5)%,(40.3 ± 2.0)%, (50.2 ± 2.5)%] were lower than those of the same dose control group with selenium intervention [(52.4 ± 1.0)%, (67.2 ± 4.0)%, (75.1 ± 5.0)%, all P ＜ 0.05], the caspase-3 expression in KBD 0.0500,0.1000 mg/L dose groups[ (40.8 ± 1.1 )%, (45.1 ± 2.1 )%] were lower than those of the same dose control group with selenium intervention[ (68.0 ± 3.0)%, (70.6 ± 3.5)%, all P ＜ 0.05 ]. Conclusions Appropriate dose of selenium supplementation (0.1000 - 0.2500 mg/L) could promote the growth of KBD chondrocyte, decrease cell apoptosis,but have a damage when the dose of selenium ＞ 0.5000 mg/L;doses of selenium that could promote the growth of KBD chondrocyte does not mean to promote the growth of normal cartilage cells in vivo.

OBJECTIVETo search for an optimum method for testicular prothesis implantation in the treatment of testis loss.

METHODSWe retrospectively analyzed the surgical methods and outcomes of 53 cases of terminal prostate cancer and 4 cases of unilateral testicular torsion treated by implantation of testicular prothesis with the polypropylene mesh.

RESULTSThe 57 male patients all received testicular prothesis with the polypropylene mesh. All the patients were satisfied with the appearance and size of the scrotum after surgery. No scrotal hematoma, prosthesis infection, or autoimmune disease occurred postoperatively.

CONCLUSIONTestis loss is not a rare condition clinically, for the treatment of which surgical implantation of testicular prothesis with the polypropylene mesh can achieve both a fine tissue compatibility and a desirable scrotal appearance.

OBJECTIVETo establish and evaluate a hypercoagulable animal model for the assessment of anticoagulants.

METHODSForty mice, thirty-two rats, and twenty-four rabbits were randomly and equally divided into control group (saline) and three ellagic acid (EA)-treated groups (low, middle, and high doses). In the mice, bleeding time (BT) was estimated with tail transaction, and clotting time (CT) with template method. Prothrombin time (PT) and the activated partial thromboplastin time (APTT) in rats and rabbits were measured by means of Quick's one-stage assay and modified APTT assay respectively. In addition, thrombin activity was estimated in rats with PT assay using a hemagglutination analyzer. The circulating platelet aggregates were detected in rabbits through platelet counting and presented as the circulating platelet aggregate ratio (CPAR).

RESULTSEA shortened BT and CT in mice, PT and APTT in rats, and increased thrombin activity and CPAR, all in a dose-dependent manner. EA also brought reduction of PT and APTT in rabbits in dose- and time-dependent manners.

CONCLUSIONEA could induce hypercoagulable state through activating coagulation system and platelets in mice, rats, and rabbits.
