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.

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

Objective A HPLC method was established for determination of the content of ATST in the aqueous humor of rabbits. MethodsThe mobile phase was consisting of methanol-1％ triethylamine(57:43) and omeprazole (OMZ) as internal standard. The detection was carried out with an ultraviolet detector operated at 235nm. 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 study the anti-tumor effect of 5-aza-2′-deoxycytidine(5-aza-dC) on breast carcinoma xenografted in nude mice. Methods The model of breast carcinoma xenografted in nude mice was established.Ten mice were randomized into the treatment group(treated with 5-aza-dC) and control group(treated with PBS).The mass of the tumors before and after treatment were measured in the two groups,and the inhibition rate of the tumor was calculated and the growth curve was drawn.Immunohistochemistry and Western blotting were employed to detect the expression of normal epithelial cell specific-1(NES1)gene. Results The inhibition rate of the tumor in the treatment group was 57.44%,which was significantly different from the control group(P

Objective:To assess the discrepancy between preoperative needle biopsy (NB)Gleason score and pathological specimen Gleason score (GS)after radical prostatectomy,and to explore the risk factors of postoperative upgrading of GS.Methods:We retrospectively evaluated 160 patients who suf-fered from biopsy proved prostatic carcinoma and performed radical prostatectomy.Age of the patients was 57 -82 years,with the average age of 71.6;prebiopsy prostate specific antigen (PSA)was 0.31 -40.32 μg/L,with the average PSA of 11.29 μg/L;body mass index (BMI)was 16.41 -32.04 kg/m2 , with the average BMI of 23.63 kg/m2;prostate volume (PV)was 9.52 -148.46 mL,with the average PV of 40.19 mL.All the patients included in the study had complete information for clinical variables, including age,BMI,prebiopsy PSA level,PV,number of biopsy cores obtained,percentage,clinical stage,and biopsy GS.Grading of NB Gleason score was compared with their corresponding radical pros-tatectomy specimens,and the discrepancy between the NB and prostatectomy specimens GS assessed. Upgrading was defined as any increase in the pathological GS over that of the biopsy GS as a total sum of primary and secondary grades or a change in the order of primary and secondary grades towards higher ones.Univariable and multivariable Logistic regression analyses were used to identify predictors of patho-logical grading changes.Results:Of the 160 patients,the specimen GS was upgraded in 49 (30.6%) patients and remained with no change in 82 (51.3%)patients.Univariate and multivariate regression analysis showed that prostate volume and biopsy GS were independent predictors with postoperative upgra-ding of GS.Age,BMI,PSA before needle biopsy,clinical stage and needle number showed no statistical significance (P >0.05).Conclusion:Lower biopsy GS and smaller prostate volume are increased risks for clinically upgrading of GS after radical prostatectomy.This fact should be kept in mind when deciding on therapy decisions for patients with prostate cancer.

Objective To study the techniques of the treatment for epidermoid with endoscope-as- sisted microneurosurgery.Methods The suboccipital,infratemporal transtentorial approach and endoscope- assisted microneurosurgery were used.Results Total resection was achieved in 10 cases,and subtotal resec- tion was made only in 2, and had no complications of all.Conclusion Endoscope-assisted microneuro- surgery can increase the total-resection rate for tumors,and reduce complications.

Objective To assess the technical feasibility and efficacy of the combined application of a flexible,self-expanding neurovascular stent(Neuroform)and Gugliebni detachable coils(GDC)in the management of wide-necked intracranial aneurysms in humans.Methods Sixty-five wide-necked aneurysms which underwent 65 endovascular procedures were performed by using intracranial stent and GDC.There was a total of 30 aneurysms at basilar artery including 16 at the basilar tip,9 at the basilar trunk and 5 at the beginning of the basilar artery.And there were 30 aneurysms located at the posterior communicating artery, and 5 aneurysms located at the vertebral artery.The Neuroform stents were deployed to cover the neck of aneurysms.Another microcatheter was introduced into the aneurysm sac through the stent interstices and then detachable coils were released to embolize the aneurysms.Results The combined procedures were successful in all of the 65 patients with wide-necked aneurysms.The stent could pass smoothly through the intracranial artery and got released.Complete occlusion was achieved in 60 patients and incomplete occlusion in 5 patients.In-stent thrombosis occurred in 2 patients.All patients recovered well.Forty-two patients had followe-up angiography at 3 to 6 months after the procedure.Among them,no filling was found for the 39 aneurysms which were densely packed,and 3 aneurysms had neck remnant.Conclusion The implantation of Neuroform stent as a complimentary device to GDC coiling is easy and safe for embolization of wide-necked intracranial aneurysms.It has great advantage for treatment of wide-necked intracranial aneurysms.
