Objective:To assess the clinical efficacy of abdominal acupuncture for subhealth insomnia.Methods:Eighty-two cases of subhealth insomnia were randomly divided into an observation group (41 cases) and a control group (41 cases).The control group was treated with conventional acupuncture.The observation group was treated with Bo's abdominal acupuncture on the basis of conventional acupuncture.Six treatments constituted one treatment course.The measuring scale of traditional Chinese medicine syndrome for subhealth state (MSSSHS) and Pittsburgh sleep quality index (PSQI) scores were compared between the two groups after two courses,to estimate the efficacy of abdominal acupuncture for subhealth insomnia.Results:One case dropped out from the observation group,while 2 cases dropped out from the control group.The MSSSHS score and PSQI score both declined after the treatment in the two groups (all P＜0.05).The MSSSHS and PSQI scores in the observation group were significantly lower than those in the control group (both P＜0.05).Conclusion:The abdominal acupuncture is effective for subhealth insomnia,and it can enhance the effect of conventional acupuncture.

ObjectiveTo compare the clinical characteristic and postoperative histopathological parameters in different prostate size and to assess the effect of prostate volume on histopathological outcomes in patients after laparoscopic radical prostatectomy. MethodsTwo hundred and sixteen patients from 2006 to 2011 who were proved prostatic carcinoma by biopsy and performed laparoscopic radical prostatectomy wewe retrospectively evaluated.All patients were divided into the small group ( ＜ 30 ml,103 cases),intermediate group(30 -60 ml,71 cases) and large group ( ＞60 ml,42 cases) according to prostate volume.Clinical variables included age,body mass index (BMI),preoperative PSA level,prostate volume,percentage of positive needles,clinical stage,and biopsy Gleason score (GS).Histopathological parameters included pathological GS,upgrading or not compared to biopsy GS,pathological stage and surgical margins status.Preoperative clinical variables and postoperative histopatholgogical parameters were compared among the 3 prostate groups. ResultsPatients with smaller prostates had lower PSA levels than those with intermediate and larger prostates (P =0.000).They also had worse histopathological outcomes such as pathological GS ( P =0.034 ),upgrading of GS ( P =0.037 ),and pathological stage ( P =0.025 ).35.0％ of patients in smaller prostate group had a positive surgical margin compare to 33.8％ and 19.0％ in intermediate and larger prostate groups,but there was no significant difference (P =0.152).ConclusionMen with smaller prostate may have more high-grade cancer and more advanced disease after laparoscopic radical prostatectomy.

ResultsThere was linearity over the range of 2. 056～41.12 ug/ml in the humor aquosus, r=0.9997. The average recovery of ATST was 94.58 ％. Intra-day and in- ter-day RSD were less than 5 ％ and 10 ％ ( n = 5), respectively. Conclusion The method is reliable. It can be used for the study on the pharmacokinetics of ATST.

Objective To observe the influence of environment stimulation on learning and memory ability and hippocampal pathology of neonatal rats with hypoxic-ischemic brain damage (HIBD).Methods The models of HIBD SD rats were established by the method of Rice, and were divided randomly into three groups: enriched environment stimulation group (EE), impoverished environment stimulation group (IE), and standard environment stimulation group (SE). The sham-operation rats were served as control group. Different environment stimulation was administrated to the rats since day 1 after HIBD.On the day 28,Morris water maze was used to evaluate the learning and memory ability. HE staining and nissl stain were employed to observe the pathological change and the number of neurons in hippocampus of rats.Results The learning and memory ability of EE group was significantly higher than that of SE group (P0.05), and the ability of SE group was higher than that of IE group ( P0.05). The number of SE group was lower than that of Sham group (P

ObjectiveTo evaluate the value of MRI diffusion weighted imaging in localization of prostate cancer with whole-mount step section pathology.MethodsWe treated 36 patients using laparoscopic radical prostatectomy from Oct. 2009 to Jun. 2010. Patients who did not have an MRI/DWI examination or a surgical history of prostate and previous hormonal therapy were excluded, leaving 19 patients in our study. We analyzed the MRI and DWI collected before radical prostetectomy surgey and the post-surgery step section pathology made by the whole mount technique. The prostatic gland was divided into six sections. Two doctors read the MRI/DWI without knowing the patients' information and scored, using a 5 point scale, for each section. The tissue was graded according to the following scale: 1-definitely no cancer, 2-probably no cancer, 3-possible cancer, 4-probable cancer and 5-definite cancer. When the average score ≥4 the region was assumed to be the prostate cancer region by MRI or MRI/DWI.ResultsIn 19 patients with 114 regions, there were 48 (42％) prostate cancer regions approved by whole-mount step section pathologically.The number of prostate cancer regions was 15 (39％), 21 (55％) and 12 (32％) in base, mid and apex parts respectively. The sensitivity and specificity of the MRI was 62.5％ and 69.7％. When considering DWI, the specificity and sensitivity was elevated to 79.1％ and 83.3％. As for the apex and mid parts, the sensitivities of MRI were a little bit low (46.7％ and 66.7％ ). But the sensitivities of localization of prostate cancer for the apex and mid of prostate were elevate to 73.3％ and 85.7％ respectively when DWI was also used.ConclusionsWith whole-mount step-section pathology, the combination of MRI and DWI can improve the sensitivity of MRI for localized diagnosis in prostate cancer, especially in apex and mid parts of the prostate.
