OBJECTIVETo investigate the relationship of the common Traditional Chinese Medicine (TCM) syndrome pattern of chronic pelvic pain syndrome (CPPS) with the contents of substance p and beta endorphin in the plasma, and provide reference data for the clinical diagnosis, differentiation and treatment of CPPS by TCM.

METHODSWe observed 98 cases of CPPS, which were classified into a lower-part damp-heat invasion group (group A, n = 32), a blood stasis-induced collateral obstruction group (group B, n = 34), and a damp-heat stagnation group (group C, n = 32) according to the TCM syndrome differentiation. Another 35 normal healthy young men were enrolled as controls. We measured the contents of substance p and beta endorphin in the plasma by immunoradiometry and ELISA, and analyzed their relationship with the TCM syndrome pattern.

RESULTSThe contents of plasma substance p were significantly higher in groups A ([1135.76 +/- 166.45] pg/ml), B ([1 337.84 +/- 170.81] pg/ml), and C ([1 210.01 +/- 162.27] pg/ml) than in the control ([574.99 +/- 113.09] pg/ml) (all P < 0.01), while the contents of plasma beta endorphin in groups A ([212.70 +/- 29.49] pg/ml), B ([157.99 +/- 24.01] pg/ml), and C ([180.81 +/- 20.20] pg/ml) were remarkably lower than that in the control ([274.73 +/- 27.64] pg/ml) (all P < 0.01).

CONCLUSIONIn the plasma of CPPS patients, the content of substance p is significantly elevated and that of beta endorphin markedly reduced, which suggests that they may be involved in the inflammatory reaction of CPPS. The levels of plasma substance p and beta endorphin can be used as valuable reference for the TCM classification of chronic prostatitis.

OBJECTIVETo compare the efficacy difference in the treatment of chronic pelvic pain syndrome of Sev-damp-heat stagnation pattern between acupoint catgut embedding therapy and western medication.

METHODSenty cases were randomized into a catgut embedding group (40 cases) and a western medication group (30 cases) at the ratio of 4 : 3. In the catgut embedding group, the catgut embedding therapy was applied to Sanyinjiao (SP 6), Quchi (LI 11), Huiyin (CV 1), Zusanli (ST 36), Zhongji (CV 3), Shenshu (BL 23), etc. The treatment was given once every two weeks, the treatment for 4 weeks was as one session and totally 2 sessions were required. In the western medication group, tamsulosin hydrochloride capsules 0. 2 mg, oral administration, once a day, and Indometacin sustained release tablets, 75 mg, once a day, 3 tablets each time were prescribed. The symptom score of TCM, score of NIH Chronic Prostatitis Symptom Index (NIH-CPSI), lecithin body number in prostatic fluid, (SAS) score of Self-Rating Anxiety Scale and score of Self-Rating Depression Scale (SDS) were compared before and after treatment in the patients of the two groups. The efficacy was evaluated in the two groups.

RESULTS(1)The total effective rate was 91. 9% (34/37) in the catgutembedding group and was 86. 2% (25/29) in the western medication group. The efficacy in the catgutembedding group was better than that in the western medication group (P<0. 05). (2) The symptom score of TCM was all reduced significantly after treatment in the two groups (both P<0.01), and the result in the catgut embedding group was superior to the western medication group (6.42 +/-2. 81 vs 10. 99+/-3. 11 ,P<0. 01). (3) Lecithin body number was increased apparently in the two groups after treatment (both P<0.01), and the result in the catgut-embedding group was superior to the western medicine group (33.56+/-5.88 vs 29. 78+/-7. 06,P<0. 05). (4) Total score of NIH-CPSI, score of pain, score of SAS and score of SDS were all improved apparently after treatment in the two groups (all P<0. 01), and the results in the catgut embedding group were superior to the western medication group (P<0. 01, P<0. 05).

CONCLUSIONThe acupoint catgut embedding therapy achieves the superior efficacy on chronic pelvic pain syndrome of damp-heat stagnation pattern as compared with conventional western medicine. This therapy relieves clinical symptoms, improves the states of anxiety and depression and increases lecithin body number obviously.

To investigate the cytotoxicity of the homemade peptide cationic liposome CDO14 and its efficacy of RNA interference (RNAi). MTT method was used to determine the cytotoxicity of the liposome to a human lung cancer cell line Luc-A549 that can express luciferase stably. Luciferase siRNA (Luc-siRNA) was transfected into Luc-A549 cells by CDO14. Contents of luciferase in the transfected cells were detected by luminous instrument and contents of total protein in these cells were detected by BCA method. Nude mice were inoculated with Luc-A549 cells in axilla to establish xenograft tumor model. Complexes of Luc-siRNA and the cationic liposomes were injected into the modeling mice via tail vein. Contents of luciferase in the transfected mice were detected by the whole body imaging system. The cytotoxicity of the homemade cationic liposome was similar to that of commercial liposome DOTAP, and lower than that of Lipo2000. The siRNA transfection efficacy mediated by CDO14 was higher than that mediated by DOTAP. The homemade peptide cationic liposome CDO14 is expected to serve as delivery vector in gene therapy because of its low cytotoxicity and high transfection efficiency.

Objective Using the function of 256-layer iCT in the determination of cardiac function and arterial elasticity index, to compare the arterial elasticity, left ventricular function and their correlation between patients with aortic dissection and non-dissected controls, and to provide a reference for the clinical treatment of patients with aortic dissection. Methods This study selected 36 cases in our emergency department,with chest, back or abdominal pain, whose clinical symptoms were highly suggestive of aortic dissection, and plain or enhanced diagnosis confirmed aortic dissection as a case group. At the same time, we randomly selected 40 cases without aortic dissection as the control group. All subjects underwent CTA one-stop scanning and measurement of elastic and cardiac function at the same level. According to the measurement results, the arterial elasticity indexes and the measured cardiac function of the case group and the control group were evaluated and compared so that to evaluate the arterial elasticity and its correlation with left ventricular function in patients with aortic dissection. Results patients's arterial expansion and compliance in patients with aortic dissection were significantly lower than the control group (P＜0.05) . The mean diameter change rate and stiffness of the patients with dissection were significantly lower than those in the control group (P＞0.05) . The difference was not statistically significant. The mean stiffness in patients with aortic dissection was significantly higher than non-aortic dissection patients. In patients with aortic dissection, the mean arterial diameter change rate, expandability and arterial stiffness showed a highly negative correlation. There was no significant correlation between arterial elasticity index and cardiac function in patients with Stanford type A and Stanford type B aortic dissection. There was no significant correlation between each elasticity index and cardiac function in the control group (r＜0.3) . Conclusion CTA one-stop scan can be used as an important measure of arterial elasticity, cardiac function and other parameters in patients with aortic dissection. Significantly lower aortic expansion and compliance, increased stiffness, insignificant changes in cardiac function, and insignificant correlation between cardiac function and each elasticity index in patients with early aortic dissection all have a clinical significance.

Hypertrophic cardiomyopathy(HCM) in the infant of diabetic mother is transient, nonfamilial condition with morphologic and functional abnormalities that resemble familial HCM. However, unlike ""true"" HCM, the cardiomyopathy of infants of diabetic mothers is usually innocent and transient, resolving during the first 6 months of life. Cardiorespiratory distress may improve within 2 to 4 weeks. Reported are two cases of infants with hypertrophic cardiomyopathy, attributed to maternal diabetes. These infants developed respiratory distress within a few hours after birth, but needed only supportive care. Echocardiogram showed myocardial hypertrophy regressing over two to four months.

The changes of microRNA expression in rat hippocampus after traumatic brain injury (TBI) were explored. Adult SD rats received a single controlled cortical impact injury, and the ipsilateral hippocampus was harvested for the subsequent microarray assay at three time points after TBI: 1st day, 3rd day and 5th day, respectively. We characterized the microRNA expression profile in rat hippocampus using the microRNA microarray analysis, and further verified microarray results of miR-142-3p and miR-221 using quantitative real-time PCR. Totally 205 microRNAs were identified and up-/down-regulated more than 1.5 times. There were significant changes in 17 microRNAs at all three time points post-TBI. The quantitative real-time PCR results of miR-142-3p and miR-221 indicated good consistency with the results of the microarray method. MicroRNAs altered at different time points post-TBI. MiR-142-3p and miR-221 may be used as potentially biological markers for TBI assessment in forensic practice.

OBJECTIVETo investigate the role of oxotremorine in arginine vasopressin (AVP)-induced hypothermia and its effects on the behavioral thermoregulatory response.

METHODSCore temperature (Tc), brown adipose tissue (BAT) temperature and motor activities were monitored in undisturbed female SD rats using radiotelemetry. The behavioral thermoregulatory response was monitored in rats using radiotelemetric temperature gradient apparatus. Effect of AVP (10 microg/kg) and oxotremorine (0.25 mg/kg) on Tc, motor activities, BAT temperature (T(BAT)), grooming activities and the behavioral thermoregulatory response were observed in rats.

RESULTSAdministration of AVP and oxotremorine caused a significant drop in Tc, T(BAT), and an increases in grooming activities, respectively. The hypothermic responses were accompanied with a preference for cooler ambient temperature. Oxotremorine augmented the reduction of Tc, T(BAT), and the elevation of grooming activities resulting from AVP, and lasting a longer time. Administration of oxotremorine followed immediately by AVP injection in rats was also shown to induce a preference for cooler ambient temperature, but there was no significant difference compared with AVP.

CONCLUSIONAVP-induced hypothermia was related with the set point temperature reduction, inhibiton of BAT thermogenesis and an increases in grooming activities. Oxotremorine could participate in peripheral AVP-induced hypothermia by affecting BAT thermogenesis and behavioral thermoregulation.
