PURPOSE: To describe the therapeutic effect and possibility of the ultra-early surgery for poor-grade aneurysmal subarachnoid hemorrhage (Hunt-Hess grades IV - V). MATERIALS AND METHODS: Nine cases with intracranial aneurysms, demonstrated by computed tomographic angiography (CTA), were treated by ultra-early surgery under general anesthesia within 24 hours from subarachnoid hemorrhage (SAH), 5 cases were treated within 6 hours and 4 cases in 6 - 24 hours. Preoperative Hunt-Hess grade: 6 cases were IV and 3 cases were V. The clinical outcome was evaluated by Glasgow Outcome Scores (GOS). RESULTS: In operation, difficult dissection occurred in 5 cases (55.6%), and rupture of aneurysm occurred and temporary obstructions were performed in 4 cases (44.4%). After clipping of aneurysm, 2 cases underwent V-P shunt because of hydrocephalus, pulmonary infection occurred in 3 cases, hypothalamus reaction accompanied with upper gastrointestinal hemorrhage in 2 cases. The clinical outcome were favorable (GOS 4 - 5) in 4 cases (44.4%), dissatisfied (GOS 2 - 3) in 3 cases (33.3%), and dead (GOS 1) in 2 cases (22.2%) when patients departed from our hospital. CONCLUSION: The ultra-early surgery can avoid early rebleeding of intracranial aneurysm, therefore, should be considered in the treatment of Hunt-Hess grade IV-V intracranial aneurysms. The appliance of CTA can make it possible to use of ultra-early surgery and improve the therapeutic effect.

Purpose: Perinatal distress, especially depression, commonly occurs during pregnancy and the first year postpartum, but this medical condition are often undiagnosed and untreated. The present study explored how women with depressive symptoms during the perinatal period who had participated in a mindfulness course applied the training and perceived its effects. Methods: This descriptive qualitative study included 16 women with probable perinatal depression who had participated in an 8-week mindfulness-based childbirth and parenting program during their pregnancy and agreed to be interviewed. One-to-one in-depth interviews were conducted and recorded following the completion of the mindfulness course, approximately 1 month after childbirth. Verbatim transcripts were analyzed using content analysis. Results: We proposed three themes and six subthemes relating to first-time mothers’ experiences during and after the group mindfulness-based intervention: learning to be aware of the body and mind (confronting awareness of physical change, managing negative feelings differently), building positive family relationships (strengthening the motherebaby bond, developing a satisfactory marital partnership), and overcoming ongoing challenges (conquering childbirth pain with confidence, accepting unexpected situations). Three main themes were generated to demonstrate how women experience the effects of mindfulness training. Conclusions Mindfulness-based interventions helped the participants develop insight into their mood and physical changes and accept their childbirth process. Therefore, mindfulness education programs can be incorporated into prenatal care to enhance the management of the depressive symptoms of perinatal women.

Objective：The aim of this study was to investigate the distribution of carcinoembryonic antigen (CEA) in colorectal cancerous tissue and to evaluate its clinicobiological significance, especially its prognostic value. Methods: Distribution of tissue CEA in 189 patients with colorectal cancer were detected with immunohistochemical method, and its relationship with many clinicopathological parameters was analyzed with SPSS software. Results: CEA distributed in both tumor tissue and normal mucosa but there was a significant difference between them. Staining positive rate of CEA in tumor tissue was 96.3％ , with 52.4％ strong and 36.5％ moderate. While in normal mucosa it was 17.4％ , with 16.2％ weak and 1.2％ moderate. There was a close relationship between tissue CEA and many clinicopathological parameters, such as differentiation, invasion depth, metastasis to regional lymph node, preoperative serum CEA level, postoperative tumor recurrence, metastasis, and postoperative survive. Conclusions: CEA overexpression in colorectal cancer tissue. Tissue CEA is a good prognostic indicator for colorectal cancer reflecting its clinicobiological features. Combining tissue CEA with serum CEA level should be better for predicting prognosis,and patient with both elevated preoperative serum CEA level and strong expression of CEA in tumor tissue indicates the worst prognosis.

OBJECTIVETo investigate the effect of phosphodiesterase type 5 (PDE5) small interfering RNA (siRNA) on cyclic guanosine monophosphatethe (cGMP) in the smooth muscle cells of human corpus cavernosum, and to provide laboratory evidence for the application of the RNA interference (RNAi) technique for the treatment of erectile dysfunction.

METHODSThe recombinant adenovirus rAd5-shRNA-PDE5A3 expressing three pairs of specific shRNA was constructed successfully. The smooth muscle cells of human corpus cavernosum were divided into an experimental, a negative control and a blank control group, and transfected respectively with rAd5-shRNA-PDE5A3, adenovirus rAd5-mock and phosphate buffered saline. The concentration of cGMP was measured by radioimmunoassay at 24, 48 and 72 hours after transfection, and the effect of rAd5-shRNA-PDE5A3 was detected on the cGMP in the smooth muscle cells of the corpus cavernosum.

RESULTSThe cGMP level in the smooth muscle cells of the corpus cavernosum was significantly higher in the rAd5-shRNA-PDE5A3 group than in the rAd5-mock control and blank control groups (P < 0.05), most significantly at 72 hours after transfection.

CONCLUSIONThe rAd5-shRNA-PDE5A3 can obviously increase the cGMP level in the smooth muscle cells of human corpus cavernosum, and enhance the inhibition of the PDE5 gene.
