Objective:To compare the concordance between subjective experience and clinician-rated in different treatment phrase of elderly patients with depressive disorder,and to explore the relevant factors.Methods:Sixty-nine consecutive elderly patiems with depressive disorder diagnosed with International Classification of Diseases-10 criteria were included.The Visual Scale for Depression(VSD) were used to evaluate subjective experience of depression,while the Hamilton Depression Scale (HAMD),Hamilton Anxiety Scale (HAMA),Minimum Mental State Examination (MMSE) were used by clinician to evaluate depression symptom,anxiety symptom and cognition at baseline,2-,4-and 52-week of the treatment respectively.Results:Compared with baseline,VSD scores were increased at 2 weeks and 4 weeks [(2.7 ± 1.6),(5.3 ± 2.0) vs.(7.0 ± 1.8),P ＜ 0.001],HAMD scores were decreased at 2 weeks and 4 weeks [(36 ± 11),(17 ±9) vs.(9 ±8),P ＜0.001],HAMA scores were decreased at 2 weeks and 4 weeks [(27 ± 10),(14 ±8) vs.(7 ±6),P ＜0.001].No significant differences were found between 4 weeks and 52 weeks.There was no correlation between VSD and HAMD scores at baseline and 2 weeks.There were significant correlations among scores of VSD and HAMD(r =-0.31,-0.74,Ps ＜ 0.05),HAMA (r =-0.36,-0.76,Ps ＜ 0.05) at 4 weeks and 52 weeks.Using logistic regression analysis,the concordance between VSD and HAMD related with the factors of HAMD,higher scores of anxiety/somatization factor were associated with lower concordance (OR =0.87),and higher scores of weight factor (OR =1.86),diurnal variation factor (OR =2.00),hopelessness factor (OR =1.13) were associated with higher concordance.Conclusion:Compared with acute depression phase,concordance between subjective experience and clinician-rated for depression may be higher at depression remission phase in elderly patients with depression,which suggests that characteristics of depression symptom may have a certain impact on the self-awareness for depression experience.

Objective To explore the changes of nitric oxide(NO) and superoxide dismutase(SOD) in the serun and intestine mucosal and the treatment of ulcerative colitis(UC) with tanshinon in rats,Methods 30 mg of trinitro-benzene-sulfonic acid (TNBS) dissolved in 0.85ml of 50% ethanol was administrated intrarectally in Sprague-Dawley female rats to induce experimental colitis.After 7 days,the rats were divided into normal control, 0.9% saline and treatment group tanshinon 2ml?kg~(-1)?d~(-1) were intravenously.The therapeutic effect was evaluated by measuring the ponderal index,the surface area of the ulcers,macroscopical and histological score,activity of NO and SOD were measured in colonic tissue and serum all rats.Results Compared with the saline group,the ponderal index,the surface area of the ulcers,macroscopical and histological score,activity of NO level in the serum and intes- tine mucosal was decreased and the SOD increased of significantly in the treatment group(P

Objective To investigate the three-dimensional structure of normal male canine prostat- ic duct and acinus system,and to study the mechanism of intraprostatic urinary reflux(IPUR)resulting from high pressure of the posterior urethra by experiment.Methods Using scanning electron microscopy (SEM)and corrosion casting methods,high pressure of the prostatic urethra was produced based upon IPUR in normal male canines.Acrylonitrile-butadiene-styrene(ABS)casting solution was injected into 8 Beagle canines'normal prostates to induce intraprostatie resin solution reflux.Results Six casting molds of nor- real canine prostate specimens were obtained,and the casting failed in 2.By corrosion and casting treatment, the prostate appeared to consist of several glandular lobes.The columnar apophyses of glandular surface were observed.The most glandular ducts pointed outward from urethral peristome.Each glandular duct system was made up of many bifurcated branches from the bough as a duct tree.More than 90% of the bifurcations were Y-shaped,and 6 bifurcated branches were rarely seen.The tip of the duct was vesicular.The diameter and length of the bough were(0.37?0.14)mm and(1.14?0.04)mm,respectively.The intersectional angle of urethra and peripheral glandular duct was the biggest.Peripheral glandular duct was perpendicular or con- verse to urinary flow.Peripheral glandular aeinus appeared elliptic and velvet.The mesh-like and crater-like depressions were shown on the surface of central glandular aeinus.Ejaculatory ducts independently and branchlessly entered the urethra.Conclusions The resin corrosion casting methods combined with SEM can clearly show the three-dimensional structure of normal male canine prostatic duct and acinus system. IPUR may easily occur in the peripheral glands from the morphological view.It is suggested that prostatitis occurs more commonly in peripheral glands,confirming a fact that high pressure of the posterior urethra can induce IPUR.

OBJECTIVETo examine whether TLR-4 has an effect on hemorrhage induced changes in lung, and to investigate the change of heme oxygenase-1 (HO-1) on acute lung injury (ALI) induced by hemorrhagic shock in mice.

METHODSForty-eight male mice, including C3H/HeN mice and C3H/HeJ mice, were randomly divided into sham group (n=12), hemorrhagic shock group with twelve mice in each phase. Blood pressure (BP) was monitored continuously by attaching carotid artery catheter to a strain gauge pressure transducer/ polygraph. Arterial blood samples were taken for blood gas analysis. A mouse model of non-lethal hemorrhagic shock and resuscitation was used to observe pulmonary myeloperoxidase (MPO) activity and wet/dry weight ratio (W/D). The expression of HO-1 was observed by means of RT-PCR and immunohistochemistry. IL-6 and IL-10 in lung tissue homogenate were assayed by enzyme-linked immunosorbent assay (ELISA). The pulmonary pathologic changes were observed under electron microscope and light microscope.

RESULTSCompared with sham group, the expression of HO-1 in lung tissue was significantly higher in Hem 24 h and Hem 48 h of C3H/HeN mice (P less than 0.01). The expression of HO-1 mRNA and the levels of IL-6, IL-10 and MPO in lung tissue were markedly increased in Hem 24 h (P less than 0.01 or P less than 0.05); Compared with C3H/HeN mice, the expression of HO-1 mRNA and the levels of IL-6 and IL-10 in C3H/HeJ mice significantly decreased in Hem 24 h and Hem 48 h (P less than 0.01 or P less than 0.05), and the W/D, MPO in C3H/HeJ mice were obviously lower in Hem 24 h (P less than 0.05). The injuries of lung tissues after hemorrhagic shock have been demonstrated by histological examination with electron microscope and light microscope.

CONCLUSIONSTLR-4 and HO-1 might modulate the balance of pro- and anti-inflammatory processes in inflammatory reaction of hemorrhagic shock-induced ALI, and the activation of Toll-like receptor might induce the transcription activity of HO-1, which may play a key role in acute lung injury.

OBJECTIVETo investigate the relationship of seasonal variation with pre- and post-thaw semen parameters as well as the cryosurgical of human spermatozoa.

METHODSA total of 6 414 semen samples were collected from 1 135 donors aged 22 - 32 years by Zhejiang Human Sperm Bank, and divided into spring, summer, autumn and winter groups according to the time of collection. All the samples underwent routine seminal analysis, and the sperm parameters were compared between different seasons. The sperm specimens were cryopreserved in aliquots and analyzed after thawing.

RESULTSThe semen volume was (2.92 +/- 1.17) ml in spring, significantly higher than in summer, autumn and winter ([2.71 +/- 1.07 ], [2.74 +/- 1.15] and [2.83 +/- 1.15] ml, P < 0.05). Sperm density was the highest in autumn ([105.60 +/- 39.76] x 10(6)/ml) as compared with the other three seasons ([101.18 +/- 40.16] x 10(6)/ml, [93.54 +/- 35.10] x 10(6)/ml, and [101.29 +/- 38.37] x 10(6)/ml, P < 0.05). The sperm progressive motility was the highest in spring ([58.49 +/- 10.04] %) and the cryosurgical of sperm the lowest in summer, with statistically significant differences from the other groups (P < 0.05).

CONCLUSIONSeasonal variations affect human semen quality and cryosurgical of sperm. The semen volume, the percentage of progressive motile sperm, the cryosurgical of sperm, and the post-thaw density of progressive motile sperm are higher in spring than during the rest of the year.

OBJECTIVEAn electric monitor of bruxism had been invented in order to evaluate the curative effect of cuspid occlusal upheaving splint and stabilization splint.

METHODS20 patients with bruxism were randomly divided into two groups. A cuspid occlusal upheaving splint or a stabilization splint was fabricated respectively for patients. The vertical dimension for each splint was 0.5 mm lower than mandibular postural position. Sleeping time, bruxist time and times of bruxism were recorded with bruxism monitor that was invented for studying bruxing.

RESULTSThe bruxist time and the times of bruxism were decreased obviously in patients with cuspid occlusal upheaving splint, while no significant difference was shown before and after using the stabilization splint.

CONCLUSIONSThe bruxism monitor can automatically measure and record the data of bruxism with splint, which is valuable for clinic. The curative effect of cuspid occlusal upheaving splint is better than that of stabilization splint for treating bruxism.

OBJECTIVETo compare the criteria of sperm morphology evaluation in the fifth edition of WHO Laboratory Manual for the Examination and Processing of Human Semen and those in the fourth edition, and to know the changes in the criteria of sperm morphology evaluation in the new edition.

METHODSNine technicians from Zhejiang Human Sperm Bank evaluated the morphology of 1 000 spermatozoa in 96 sperm morphological pictures according to the criteria in the fourth and fifth editions of WHO Laboratory Manual, respectively.

RESULTSThe percentage of morphologically normal sperm by the criteria of the fifth edition was (26.50 +/- 5.06)%, significantly higher than (11.39 +/- 3.17)% by the fourth edition (P < 0.05), while the rates of sperm head and tail defects based on the former were (64.26 +/- 7.66)% and (10.92 +/- 2.03)%, significantly lower than (76.11 +/- 8.18)% and (39.89 +/- 3.85)% according to the latter (P < 0.05). There were no significant differences in the rates of sperm midpiece defects and excessive residual cytoplasm by the fifth and fourth editions ([16.46 +/- 3.08]% vs [15.22 +/- 3.51 ]% and [4.24 +/- 1.66]% vs [3.87 +/- 1.68]%, P > 0.05).

CONCLUSIONThe criteria of sperm morphology evaluation in the fifth edition of WHO Laboratory Manual are less strict than those in the fourth, and the percentage of morphologically normal sperm is higher according to the fifth edition.
