Abstract Psychological stress is a significant contributing factor for the decline in male sperm quality. In terms of the psychological mechanism, the decline of sperm quality due to psychological stress is associated with increased perceived stress and different coping strategies. External sources of stress can elevate stress perception, then affect sperm quality, while coping strategies may modulate the impact of stress perception on sperm quality. In terms of the physiological mechanism, psychological stress disrupts the normal functioning of the sympathoadrenal system, hypothalamic-pituitary-adrenal axis and hypothalamic-pituitary-gonadal axis, leading to disturbances in the essential endocrine environment for sperm production. This review synthesizes the psychological and physiological mechanisms through which psychological stress influences male sperm quality, providing insights into the prevention and treatment of male infertility.

Objective To explore the clinical value of color Doppler ultrasonography in the diagnosis of uterine carcinosarcoma (UCS).Methods The clinical data and ultrasonographic manifestations of 63 cases of UCS proved by operation and pathology in Obstetrics and Gynecology Hospital of Fudan University from January 2003 to December 2014 were retrospectively analyzed.The clinical features and characteristics of ultrasound images in UCS were summarized and classified according to their ultrasonographic features.Results It mostly occurred in postmenopausal women (77.8％).The average age of the 63 patients of UCS was (57.7 ± 11.5) years old.The most common symptoms of UCS were postmenopauseal vaginal bleeding (57.1％),menstrual disorders (20.6％),vaginal discharge (11.1％),uterine mass or thickened endometrium (11.1％).Tumor marker CA125 was evaluated in 36 women and found to be elevated in 15 women (41.7％),60％ of which (9/15) was less than 200 U/mL.Six cases (16.7％) of relative higher level of serum CA125 (＞ 200 U/mL) were at advanced stage or with malignant ovarian tumors.The sonographic findings of UCS had three types:Uterine cavity type (71.4％),endometrium type (14.3％),and myometrium type (14.3％).The ultrasonographic characteristics of uterine cavity type and myometrium type were fuzzy boundary,irregular shape,and internal uneven echo.Color doppler flow image showed rich blood signals and low resistance index (0.55 + 0.11) of the surrounding and internal artery of the lesions.The large volume of lesion was the characteristic of myometrium type.Conclusions UCS is a very aggressive and extremely rare tumor with the symptoms of postmenopauseal vaginal bleeding,menstrual disorders,vaginal discharge,et al.There are three types of sonographic findings of UCS:uterine cavity type,endometrium type and myometrium type.To strengthen the understanding of UCS and combined with clinical manifestations,the transvaginal color Doppler ultrasound was helpful to early detection,early diagnosis and making the appropriate treatment.

Objective To investigate the protective effect of bicyclol tablets on drug-induced hepatic injury in patients with severe psoriasis.Methods One hundred and six patients with severe psoriasis and drug-induced hepatic injury were enrolled in this study,and randomly divided into 2 groups:bicyclol group (53 cases) treated with oral bicyclol tablets (25 mg thrice a day) for 8 weeks,diammonium glycyrrhizinate group (53 cases) treated with diammonium glycyrrhizinate capsules (150 mg thrice a day) for 8 weeks.Serum biochemical indices of hepatic function were measured before and after treatment,therapeutic efficacy was evaluated,and adverse reactions were observed and recorded after treatment.Intergroup and intragroup differences in these parameters were assessed.Results During the treatment,3 patients were lost to follow up.After treatment,serum biochemical indices of hepatic function markedly improved in both the bicyclol group (52 cases) and diammonium glycyrrhizinate group (51 cases) (both P ＜ 0.01),and the bicyclol group showed a better treatment response than the diammonium glycyrrhizinate group (P ＜ 0.01).The marked response rate was 71.15％ and 47.06％ (P ＜ 0.05),and the response rate was 84.62％ and 66.67％ (P ＜ 0.05),respectively,in the bicyclol group and diammonium glycyrrhizinate group.No adverse reactions related to tested drugs were observed in either of the two groups.Conclusion Bicyclol can attenuate antipsoriatic drug-induced hepatic injury with good safety.

Aim To study the antipsychotic effects of l-Scoulerine ( l-SLR) . Methods NMDAreceptorantag-onist MK-801 was used to induce the positive and neg-ative symptoms of schizophrenia and cognitive impair-ment in animal models. The effects of l-SLR were eval-uated on schizophrenia induced by MK-801 and on ex-trapyramidal system. Results l-SLR (10,15 mg · kg - 1 , ip) could suppress pre-pulse inhibition damage in rats induced by MK-801 (0. 3 mg·kg - 1 , ip); l-SLR(30 mg·kg - 1 , ip) could inhibit climbing behav-iors in mice induced by apomorphine, which suggested that l-SLR had significant inhibiting effects on the posi-tive symptoms of schizophrenia by MK-801 and apo-morphine. l-SLR could also induce social contact inhi-bition and cognitive impairment induced by MK-801 (0. 2 mg · kg - 1 , ip), which proposed that l-SLR could improve the negative symptoms and cognitive im-pairment by MK-801. Catalepsy in mice could be caused by the treatment dose of haloperidol (0. 8 mg· kg - 1 , ip), not by that of l-SLR(30 mg·kg - 1 , ip). Conclusion I-SLR has significant effects on the posi-tive and negative symptoms of schizophrenia and cogni-tive impairment and, the effect of l-SLR under effective dose on extrapyramidal system is obviously much less than that of haloperidol and l-SPD.
