Diminished ovarian reserve(DOR)is associated with a reduced quantity and/or quality of retrieved oocytes,usually leading to low numbers of retrieved oocytes and poor reproductive outcomes.DOR may potentially progress to premature ovarian insufficiency and premature ovarian failure,which have adverse impacts on women's health.There is currently no effective clinical treatment to rescue ovarian function.The limited availability of human ovarian tissues and medical ethics issues mean that animal models are crucial for improving our understanding of the molecular pathogenesis of DOR and identifying preventive and therapeutic targets.This review thus aims to summarize the techniques and strategies used to establish rodent models of DOR,to provide a reference for future studies.

One hundred Alzheimer′s disease (AD) patients with behavioral and psychological symptoms of dementia (BPSD) treated with donepezil+risperidone group ( n=50, group 1) or hydrochloride memantine+risperidone group ( n=50, group 2) in geriatric departments of Hangzhou Seventh People′s Hospital were enrolled in the study. Montreal cognitive assessment scale (MoCA), positive and negative syndrome scale (PANSS), treatment emergent symptom scale (TESS) were applied for evaluation; and blood routine examination, blood biochemistry, eletrocardiogram were performed in two groups before and after treatment. After treatment, MoCA score in group 2 (16.10±3.90) was significantly higher than that in group 1 (18.14±3.71)( t=-3.99, P<0.01), and PANSS score in group 2 (86.66±6.62) was significantly lower than that in group 1 (109.50±11.51; t=12.67, P<0.01). The incidence rates of dry mouth (16%,8/50), extrapyramidal side effects (10%,5/50) and the total score of TESS (3.92±2.02) in group 2 were markedly lower than those of group 1 [44%(22/50), 36%(18/50), (12.49±1.45);χ 2=9.33,9.54, t=17.90,all P<0.01]. Meanwhile, group 2 had significantly lower influences on the levels of blood lipids and fasting blood glucose (all P<0.01). The risperidone dose used in group 2 was significantly lower than that in group 1 [(2.06±0.50) vs. (3.85±0.89)mg, t=14.40, P=0.04].The results suggest that hydrochloridememantine combined with risperidone is more effective with less side effects compared to donepezil combined with risperidone for AD patients with BPSD.

OBJECTIVES: Pseudolaric acid B (PAB) has been shown to inhibit the growth of various tumor cells, but the molecular details of its function are still unknown. This study investigated the molecular mechanisms by which PAB induces apoptosis in HeLa cells. METHODS: The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assays were performed to investigate the effect of PAB treatment in various cervical cancer cell lines. Annexin V/propidium iodide staining combined with flow cytometry and Hoechst 33258 staining were used to assess PAB-induced apoptosis. Additionally, we performed bioinformatics analyses and identified a paired box 2 (PAX2) binding site on the BAX promoter. We then validated the binding using luciferase and chromatin immunoprecipitation assays. Finally, western blotting assays were used to investigate PAB effect on the Wnt signaling and the involved signaling molecules. RESULTS: PAB promotes apoptosis and downregulates PAX2 expression in HeLa cells in a time- and concentration-dependent manner. PAX2 binds to the promoter of BAX and inhibits its expression; therefore, PAX2 inhibition is associated with increased levels of BAX, which induces apoptosis of HeLa cells via the mitochondrial pathway. Additionally, PAB inhibits classical Wnt signaling. CONCLUSION: PAB effectively inhibits Wnt signaling and PAX2 expression, and increases BAX levels, which induce apoptosis in HeLa cells. Therefore, PAB is a promising natural molecule for the treatment of cervical cancer.

Objective To explore the clinical effects of aripiprazole on post-schizophrenic depression and its effects on patients' life quality. Methods A total of 82 patients with post-schizophrenic depression who were admitted to our hos-pital from January 2011 to July 2014 were selected as research subjects. They were randomly assigned to control group(n=41)and experiment group(n=41). The control group was given risperidone, and the experiment group was given aripiprazole. Changes of PANSS scores, HAMD scores, CGI scores and QOL-100 scores between the two groups were compared. Results PANSS scores, HAMD scores, CGI scores and QOL-100 scores between groups before the treatment were not statistically different(P>0.05). After the treatment, scores in the two groups improved significantly compared to those before the treatment, and the differences were statistically significant(P<0.05). Psychopathology score in the experiment group 24 weeks after the treatment was lower than that in the control group. Scores of negative symptom scale and HAMD scores 12 weeks and 24 weeks after the treatment were both lower than those in the control group. CGI score 12 weeks after the treatment was lower than that in the control group. QOL-100 scores was higher than that in the control group. The differences were all statistically significant (P<0.05). Differences of adverse events were not statistically significant(χ2=0.179, P>0.05). Conclusion After the treatment of aripiprazole for patients with post-schizophrenic depression, depression and negative symptoms are improved greatly, and the life quality is enhanced.

Objective To evaluate the clinical value of ultrasonography detecting the poster urethrovesical angle(PUVA) in diagnosis of stress urinary incontinence(SUI).Methods From Jan.2006 to Dec.2008,the PUVA in resting phase (PUVA-r) and stress phase( PUVA-s) between with SUI and 100 healthy women were measured by color Doppler ultrasound,including 57 cases in SUI degree Ⅰ,22 cases in SUI degree Ⅱ,5 cases in SUI degree Ⅲ.Results (1) The PUVA-r and PUVA-s were (130±29) and (158±36)in SUI patients,which were significantly higher (113±19)and (115±23)in control group (P<0.01).(2) Correlation analysis showed that PUVA-s was positively correlated with the severity of SUI ( P < 0.01).(3) The area under the receiver operating characteristic curves (ROC) of PUVA-s was 0.82 (95% CI:0.76-0.89) between SUI patients and healthy women.When PUVA-s ≥ 140 ° was chosed as the cut-off value,the specificity,accuracy rate and positive predictive value in diagnosis of SUI were 84%,79%,81%,which were significantly higher than those when cut-off value of PUVA-s ≥ 120(54%,68%,62%; P < 0.05 ).Conclusion The PUVA-s in SUI patients are significantly increased and is positively correlated with the severity of SUI,which are indicated that PUVA-s ≥ 140should be used as cut-off value in diagnosis of SUI by ultrasonography.
10.Diagnosis and Treatment of Parkinson's Disease Following Depression(review)
Chinese Journal of Rehabilitation Theory and Practice 2009;15(6):545-547
Depression is a common comorbid condition in Parkinson's disease (PD) and a major contributor to poor quality of life and disability. However, depression can be difficult to assess in patients with PD due to overlapping symptoms and difficulties in the assessment of depression in cognitively impaired patients, several rating scales have been used to assess depression in PD. Tricyclic and new selective antidepressants including serotonin and noradrenaline reuptake inhibitors, selective serotonin reuptake inhibitors, selective noradrenaline reuptake inhibitors appear to be effective in treating depression in PD. Clinical investigation indicate antidepressive effects in PD.
