Objective The objective of digitalized patient records control is to meet some new demands set on patient records control under the new circumstances. Methods A computer system for digitalized patient records control and supporting processing, management and applications setups were established. Results The system put the contents of the patient records into various categories with difierent standards and designed relatively strict means of authorization. It rendered patient records easier to use and their control more strict, making it possible to make general use of the records without access to the original documents. As a result, data loss was avoided, authority over the data was put under control, data sharing was provided, and full and convenient use of data was realized. Conclusion Digitalized patient records control, a form of shaping computer-based patient records before the latter fully comes into being, enhances the efficiency of patient records application and reduces the pressure of paper records storage. It is a practical and effective way of controlling patient records.

Objective To explore the relationship between polymorphisms of brain-derived neurotrophic factor(BDNF) gene (rs6265 and rs12273539) and cognitive impairment in depressive disorder.Methods All participants including 73 depressed patients and 71 healthy controls were received clinical and cognitive assessments at admission,and then the depression group was divided into two groups by the score of Beijing version of the Montreal Cognitive Assessment (MoCA-BJ).One was depression with cognitive dysfunction group,and the other was depression without cognitive dysfunction group,with 36 and 37 cases respectively.The polymorphisms of BDNF gene was identified by PCR-RFLP.Results No significant difference for rs6265 gene types(x2=5.18,P=0.27),A allele carries (x2 =4.28,P=0.12) and G allele carries (x2 =1.95,P=0.38) among the three groups.There was no significant difference for rs12273539 gene types,allele carries between patients without cognitive dysfunction and controls groups(P＞0.05).There was much more C-allele carries (x2=5.40,P=0.02)and less T-allele(x2=6.06,P=0.01) in patients with cognitive disorder than those in health and it was different in rs12273539 gene types between the two groups(x2=8.38,P=0.02).CC/CT/CT gene type performed different on attention function (P＜0.01).Conclusion BDNF rsl2273539(T/C) gene type has relationship with the onset of cognitive disorder in depressed patients,and there are more C-allele carries in depressive patients.The depression patients with CC gene type are worse on the attention function impairement.

Objective To explore the relationship of attentional function,coping style and depressive symptoms in depression disorders.Methods Sixty-eight depression disorder and seventy-one normal healthy people were assessed by Hamilton depression scale(HAMD),coping style questionnaire and digit span forward.Independent samples t test and hierarchical multiple linear regression analysis were used to analyze all data.Resuits Compared with the control group,depressed patients had higher blaming(0.57 ± 0.29 vs 0.29 ± 0.25,P ＜0.01),wishful thinking(0.55 ± 0.22 vs 0.42 ± 0.26,P ＜ 0.01) and avoidant (0.63 ± 0.18 vs 0.46 ± 0.21,P ＜0.0l),lower problem solving (0.67 ± 0.23 vs 0.80 ± 0.18,P ＜ 0.01),rationalization (0.51 ± 0.20 vs 0.59 ±0.06,P＜0.01) and poorer attentional function(6.90 ± 1.65 vs 7.54 ±0.98,P＜0.01) ;but there was no significant differences in support seeking score.Hierarchical multiple linear regression analysis revealed that,even when controlling for age,sex,low score of support seeking were independently predicted attentional function impairment (β =-0.25,P＜0.05).In addition,the use of support seeking was found to mediate the relationship between digit span forward and retardation completely.Conclusion Retardation indirectly influence the attention function by the mediating of support seeking.

Objective To investigate the characteristics of cognitive dysfunction in patients with depression,and identify the correlation between cognitive dysfunction and serum brain-derived neurotrophic factor (BDNF) level.Methods All participants including 73 depressed patients and 71 healthy controls were received clinical and cognitive assessments at admission,the depression group was divided into two groups by the score of Beijing version of the Montreal Cognitive Assessment (MoCA-BJ),one was depression with cognitive dysfunction group which had 36 cases,the other was depression without cognitive dysfunction group which had 37 cases.Concentration of BDNF was measured by the ELISA method.Results Cognitive impairments were found in numerous cognitive domains of depressed patients,including visuospatial and executive abilities,attention,delayed recall and orientation(P ＜ 0.05).The incidence of cognitive dysfunction in depression was 49.3％.There was not significant difference between two depressive groups (depression with cognitive disorder(12.08 ± 7.08)ng/ml,depression without cognitive disorder (12.22 ± 7.93)ng/ml,P ＞ 0.05),and the levels were significantly lower than that in healthy people ((16.55 ± 7.47) ng/ml,P＜ 0.01),and serum BDNF level had no positively relevant with different cognitive functions (P ＞ 0.05).Conclusion Depression patients have cognitive dysfunction in numerous cognitive domains,including visuospatial and executive abilities,attention,delayed recall and orientation.Serum BDNF level is closely related with depression,while,it has no obvious relationship with cognition function in depression.

Objective To evaluate the diagnostic value of urine-based prostate cancer antigen 3 ( PCA3 ) score in detecting prostate cancer during initial prostatic biopsy .Methods Urine was collected after digital rectal examination ( DRE) ( three strokes per lobe ) from 248 men before prostate biopsy .The specimens were collected between January 2010 and December 2012.The expression of PCA3 mRNA and prostate specifc antigen (PSA) mRNA was determined by quanti-tative real time polymerase chain reaction ( qRT-PCR ) .PCA3 scores were calculated by PCA 3 mRNA/PSA mRNA × 1000 .The ability of the PCA3 score to predict the biopsy outcome was assessed with AUC-ROC analysis and compared with the serum PSA levels.Results The rate of positive prostate biopsy was 32.3%(80 patients with positive prostatic biopsy versus 168 patients with negative prostate biopsy ) .PCA3 scores were significantly higher in patients with positive biopsy than in those with negative biopsy results (P<0.001).The ROC curve analysis demonstrated that the area under the ROC curve (AUC) of serum total PSA (tPSA), PCA3 score and the duplex model combining tPSA and PCA 3 score was 0.620, 0.693 and 0.724, respectively.Further analysis of the diagnostic performance of PCA3 score revealed that at a cut-off of 90.2456, the sensitivity was 67.5%and the specificity was 61.9%for discriminating positive biopsy from negative biopsy. The duplex model combining tPSA and PCA 3 score represented a better approach than tPSA alone in PCa diagnosis by pros-tatic biopsy (P=0.011), but there was no statistically significant difference between tPSA and PCA 3 score (P=0.160). In addition , a comprehensive diagnostic model based on multiple risk factors of prostate cancer combined with PCA 3 score could further improve the predictive accuracy of prostate cancer .Conclusion PCA3 could be a good predictor of prostate cancer in initial prostate biopsy in Chinese population .The comprehensive diagnostic model can improve the diagnostic potency .Further large-scale multicenter studies in China are needed to confirm our findings .

Objective To determine the efficacy of hysteroscopy and laparoscopy in differential diagnosis of pregnancy-related diseases,including gestational trophoblastic neoplasia(GTN),incomplete abortion and ectopic pregnancy.Methods Twenty-seven patients with a suspected diagnosis of GTN were transferred to Peking Union Medical College Hospital from September 2003 to March 2006,and underwent hysteroscopy and laparoseopy.Clinical data of patients were reviewed retrospectively.Most patients had abnormal vaginal bleeding and persistently elevated plasma beta human chorionic gonadotropin(?-hCG) level for a median(53?37)days(range,15-125 days)after evacuation.Ultrasound revealed a lesion with affluent blood flow in intrauterine,unilateral horn of uterus,or myometrium.No positive findings were revealed by computerized tomography or X-ray of the chest in all patients.Eleven patients underwent evacuation under hysteroscope,10 patients were diagnosed and treated by laparoscopy,and 6 by hysteruscopy and laparoseopy.Results Choriocarcinoma was diagnosed in 4 patients,who achieved complete remission by chemotherapy later.The diagnosis of GTN was ruled out in the other 23 patients, including cornual pregnancy in 12,pregnancy in rudimentary horn in 1,and incomplete abortion in 10,who were cured by hysteroscopic and laparoscopic surgery and postoperative adjuvant single dose methotrexate.Conclusions The major causes of pregnancy-related abnormal bleeding include incomplete abortion,eetopic pregnancy,and GTN.Hysteroscopy and laparoseopy are effective alternative of diagnosis for differentiation of GTN from non-GTN and can also offer therapeutic treatment.

0.05).Compared with control group,significant decrease in positive group was found in the interval from first evacuation of HM to resolution of serum ?-hCG level,(83?18) days versus(126?31)days(P0.05).Conclusions Once HM is diagnosed,evacuation should be performed as soon as possible,the later the evacuation begins,the higher the risks of lung metastasis and chemotherapy are.It is not necessary to worry about lung metastasis before evacuation of HM,the outcome of post- chemotherapy is very good.
