Objective To investigate curative effect thymoleptics with couple therapy for the patients with postpartum depression (PPD) Methods 27 patients first time diagnosed with PPD consistent with DSM-Ⅳwere randomly divided into study group and control group.The study group received regular thymoleptics with couple therapy,a control group were administered solo thymoleptics.Hamilton Depression Rating Scale(HAMD-17) and Edinburgh Postnatal Depression Scale (EPDS-10) and OLSON marriage quality questionnaire assessed the efficacy of each group before treatment and after 12 weeks treatment.Results (1) According to the total effective rate,there was no significantly differences in two groups after 12 weeks treatment from evaluation of HAMD-17>(P0.05),but complete remission of study group was higher than control group (78.6% ,46.2% ;P<0.05).(2) After 12 weeks treatment there were significantly differences in mean scores of HAMD-17 and EPDS-10 between two groups (P<0.05).The most decreased scores of HAMD-17 and EPDS-10 was found in the study group,and mean scores of each group was lower than pretherapy(P<0.05).(3) There was no significant difference on the scores of eight factors in OLSON marriage quality questionnaire between the two groups before treatment (P>0.05).After 12 weeks treatment the study group had higher score than control in seven factors in addition to sexual life factor (P<0.05).Conclusion Thymoleptics with couple therapy can improve the marriage quality and increase curative effects outstrip solo thymoleptics for the patients with postpartum depression.

Rat brain development is a complicated process.There are significant changes of histology, cytology and molecular biology in the process of fetal and postnatal brain development.The basic structure of brain has formed in the prenatal period.While the formation of connections between different parts and the improvement of the function of the brain occur after birth, during which many of the variations are bases of the nervous system diseases, so the postnatal brain development is still very important.Although the concept of brain microenvironment has been proposed more than 150 years ago, the research about the changing extracellular space ( ECS ) during the postnatal brain development has yet to gain significant progress.The author reviewed the anatomical and physiological characteristics of ECS in the process of postnatal development of the rat, stating the important role of ECS in the individual development, which is expected to provide reliable evidences for the explore of mechanisms and effective treatment approaches of pediatric development related nervous system diseases.

Objective To investigate whether intrathecal administration of corticotrophin releasing factor(CRF) has an efficacy on visceral hypersensitivity in irritable bowel syndrome model rat.Methods Thirty rats were randomly divided into three groups(n=10 ).After establishment of irritable bowel syndrome rat model were intrathecal injected with CRF or preemptive peritoneal injected with CP-154526,which is inhibitor of CRF-1 receptor,and the control group to give saline.After experiment all rat with the method of rectal balloon distention,the perception thresholds and the number of abdominal withdrawal reflexes (AWR) of different balloon volume were observed.Results The perception threshold of intrathecal administration of CRF group was(0.62±0.10)ml and higher than other two groups [(0.52±0.09)ml,(0.56±0.08)ml;F=3.25,P＜0.05].At the same time,the number of AWR to the lower balloon content (1.0 ml) was(9.10±1.97)in intrathecal administration of CRF group slightly lower than other two groups[(14.4±1.71),(15.6±2.32);F=29.4,P＜0.01],but no difference was found to the higher balloon content (1.5 ml and 2.0 ml).Besides,the areas and OD value of c-fos positive neurons in cornu posterius medullae spinalis in group with intrathecal administration of CRF were significantly lower than other two groups (P＜0.05).Conclusion Intrathecal administration of CRF can degrade the visceral hyperensitivity in irritable bowel syndrome model rat,and lower expression of c-fos in CNS is probably involved in the process.

OBJECTIVETo explore the procedures of dynamic infusion cavernosometry and cavernosography (DICC) and their application in the diagnosis and classification of venous erectile dysfunction (VED).

METHODSThis study included 103 ED patients, aged 20 to 43 years, highly suspected of VED, with disease courses of 4 months to 6 years. DICC was performed and analyses were made on the results, especially the parameters of flow-to-maintain (FTM) and pressure decay (PD) in the corpus cavernosum.

RESULTSBased on the parameters of FTM and PD, 21 of the patients were normal, 5 were suspected of VED, 39 had mild VED, 25 had moderate VED, and 13 had severe VED. Penile subcutaneous hematoma was found in 4 of the patients, all recovered after 3 to 5 days, with no other complications.

CONCLUSIONDICC is a reliable, safe and minimally invasive method for the diagnosis and classification of VED.

To investigate the roles of apoptosis and the Fas system (Fas, Fas ligand, soluble Fas) in the process of liver cirrhosis (LC) converting into hepatocellular carcinoma (HCC), expression of Fas and Fas ligand (FasL) in 49 LC and 36 HCC samples was detected by immunohistochemical method. Apoptosis was detected by terminal deoxynucleotidyl transferase mediated dUTP nick end labeling (TUNEL) method. Serum soluble Fas (sFas) levels in 28 cases of LC and 27 cases of HCC were measured by enzyme-linked immunosorbent assay (ELISA) method. Compared with LC, apoptotic indices (AI) in HCC tissues were significantly reduced (P<0.001), expression of Fas was decreased (P<0.05), and that of FasL was increased (P<0.05). Serum sFas levels in HCC patients were significantly higher than those in normal controls. Down-regulation of Fas expression, up-regulation of FasL expression in hepatocytes and elevation of sFas level in serum might contribute to tumor escape from immune surveillance of the body. Apoptosis and the Fas system are significantly involved in the process of liver cirrhosis converting into hepatocellular carcinoma.

Objective To investigate the feasibility to reduce radiation doses on pediatric mutidetector abdominal CT using the adaptive statistical iterative reconstruction technique (ASIR) associated with automated tube current modulation technique(ATCM).Methods Thirty patients underwent abdominal CT with ATCM and the follow-up scan with ATCM cooperated with 40％ ASIR.ATCM was used with agedependent noise index (NI) settings: NI =9 for 0-5 year old and NI =11 for ＞ 5 years old for simple ATCM group,NI =11 for 0-5 year old and NI =15 for ＞5 years old for ATCM cooperated with 40％ ASIR group(AISR group).Two radiologists independently evaluated images for diagnostic quality and image noise with subjectively image quality score and image noise score using a 5-point scale.Interobserver agreement was assessed by Kappa test.The volume CT dose indexes (CTDIvol) for the two groups were recorded.Statistical significance for the CTDIvol value was analyzed by pair-sample t test.Results The average CTDIvol for the ASIR group was (1.38 ± 0.64) mGy,about 60％ lower than (3.56 ± 1.23) mGy for the simple ATCM group,and the CTDIvol of two groups had statistically significant differences.(t =33.483,P ＜ 0.05).The subjective image quality scores for the simple ATCM group were 4.43 ± 0.57 and 4.37 ±0.61,Kappa =0.878,P ＜ 0.01 (ASIR group: 4.70 ± 0.47 and 4.60 ± 0.50,Kappa =0.783,P ＜ 0.01),by two observers.The image noise score for the simple ATCM group were 4.03 ±0.56 and 3.83 ±0.53,Kappa =0.572,P ＜ 0.01 (ASIR group: 4.20 ± 0.48 and 4.10 ± 0.48,Kappa =0.748,P ＜ 0.01),by two observers.All images had acceptable diagnostic image quality.Conclusion Lower radiation dose can be achieved by elevating NI with ASIR in pediatric CT abdominal studies,while maintaining diagnostically acceptable images.

Objective To study the possibility of establishment of an animal model of hydronephrosis by ureteropelvic junction obstruction,and to evaluate the value of CT perfusion imaging in assessment of the renal function in the animal models. Method Fifty 10-week-old male New Zealand rabbits were randomly assigned to two groups:sham-operated group with separation of the left ureter (20 rabbits),and model group (30 rabbits) with the left ureter embedded at the ureteropelvic junction under the psoas major muscle. The left kidney function in the two groups was confirmed to be normal by SPECT before operation. CT perfusion and SPECT imagings were performed to assess the left kidney function in the two groups at three months after surgery,and the results were compared with that of pathological examination. Statistical analysis was performed on the parameters of SPECT and CT perfusion imaging and glomerular filtration rate (GFR). Results The success rate of model establishment was 70%,showing pathological changes of chronic hydronephrosis. CT perfusion demonstrated that BF,BV,PS of the left renal cortex and medulla were decreased,and had a good positive correlation with the changes of GFR. Conclusions It is feasible to establish a rabbit model of chronic hydronephrosis by embedding the left ureter at ureteropelvic junction under the psoas major muscle,and CT perfusion imaging parameters can be used to evaluate the renal function in the animal models.

OBJECTIVETo compare the effects and complications of subinguinal microscopic ligation, laparoscopic transperitoneal varicocelectomy, laparoscopic retroperitoneal varicocelectomy, open retroperitoneal high ligation, and interventional embolotherapy in the treatment of varicocele.

METHODSWe conducted a retrospective study that included 632 varicocele patients treated by subinguinal microscopic ligation (group A, n = 79), laparoscopic transperitoneal varicocelectomy (group B, n = 120), laparoscopic retroperitoneal varicocelectomy (group C, n =137), open retroperitoneal high ligation (group D, n = 283), and interventional embolotherapy (group E, n = 13). We compared the baseline and 3-month postoperative semen parameters, postoperative complications, and pregnancy rate among the five groups of patients.

RESULTSThe operation time was longer in groups A ([2.02 ± 1.25] h) and E ([2.17 ± 1.02] h) than in the other three groups, while the postoperative hospital stay was the shortest in group E ([1.1 ± 0.1] d). Intestinal injury or incision bleeding occurred intraoperatively in 2 cases in group B and 1 case in group E. Postoperative scrotal edema developed in 3.7, 17, 10, and 19% of the patients in groups A, B, C, and D, respectively, but not in group E. The rate of 1-year recurrence was the lowest in group A (1.6%) and highest in group E (22%). Sperm concentration and the percentages of progressively motile sperm and morphologically normal sperm were improved postoperatively in all the patients (P < 0. 05), but there were no statistically significant differences among the five groups either in the above three parameters or in the postoperative pregnancy rate (P > 0. 05).

CONCLUSIONIn the surgical treatment of varicocele, laparoscopic retroperitoneal approach involves short operation time and few complications, subinguinal microscopic ligation has the advantages of little injury, rapid recovery, and few complications but requires specialized microsurgical techniques, and interventional embolotherapy leaves no incision scar and needs only local anesthesia and 1-day postoperative hospital stay, which is uitable for those with a contraindication to anesthesia.
