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.

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.

OBJECTIVE: To explore the relationship between the expression of EIIIA+ fibronectin in incised wound of rat's skin and injury time. METHODS: The wounding model was established by cutting the dorsal skin of 48 adult SD rats. The rats were sacrificed at the pre-set injury time as immediately, 0.5 h, 1 h, 2 h, 3 h, 4 h, 6 h, and 8 h. The skin samples were taken at the margin of wound. The expression of the EIIIA? fibronectin was detected by immunohistochemistry and Western blotting and the relationship be- tween its expression and injury time was observed. Results The expression of EIIIA+ fibronectin was not observed immediately. The basal cell of skin began to show positive expression 0.5 h after injury. With the extension of injury time, positive staining became stronger. The value of relative optical density was gradually increased with prolonged injury time by the Western blotting analysis. CONCLUSION The expression of EIIIA+ fibronectin could be used for estimation of injury time in the early stage of skin injury.

OBJECTIVETo identify and analyze the differential expression of ubiquitin C-terminal hydrolase L-1 (UCHL1) in the testis of rat offspring after maternal exposure to di-n-butyl phthalate (DBP).

METHODSForty pregnant rats were randomly divided into two groups and given DBP by gastric intubation at the dose of 800 mg/(kg x d) or none from the 14-18th day of pregnancy. Testes were harvested from the fetal and neonatal rats of the normal and exposed groups respectively at GD19 and PND22. The expression of UCHL1 was detected and analyzed by Western blot and immunohistochemistry.

RESULTSThe UCHL1 expression was 50% lower in the DBP-exposed group than in the normal controls on GD19 (P < 0.01), but showed no significant difference between the two groups on PND22 (P > 0.05). UCHL1 was mainly located in the cytoplasm and nuclei of spermatogonia, primary spermatocytes and sub-primary spermatocytes in the developmental phase of the testis.

CONCLUSIONExposure in utero to DBP affects the UCHL1 expression in testicular spermatogenic cells, disturbs the balance of the ubiquitin-proteasome system and consequently causes maldevelopment of the testis with thinner seminiferous tubules and reduced count of spermatogenic cells.

AIM: The effects of ZX-5, as nitric oxide (NO) donor, on ocular blood flow has been investigated using colored microsphere technique in previous study. The relationship between the production of NO by ZX-5 and ocular blood flow has been evaluated. ZX-5 has been shown to have strong positive effect on increasing choroidal blood flow. However,the effect of ZX-5 on retinal function recovery, the effects of its optical isomers, (R, R)-ZX-5 and (S, S)-ZX-5, on choroidal blood flow and retinal function recovery have not been studied and merit investigation.METHODS: Colored microsphere technique was used for in vivo experiments to determine choroidal blood flow of ocular hypertension (40mmHg) in rabbit eyes. Electroretinography was used to measure the b-wave recovery as an indication of retinal function recovery.RESULTS: (R, R)-ZX-5 increased choroidal blood flow at 10g/L, 50μL instillation into eyes at all time points (P＜0.05).(S, S)-ZX-5 was not effective in increasing choroidal blood flow. ZX-5 and (R, R)-ZX-5 showed significant effects in retinal function recovery after ischemia of the retina at all time points (P＜0.05); whereas (S, S)-ZX-5 did not show significant effect on recovery of b-wave after ischemia at most time points except at 120 and 240 minutes.CONCLUSION: ZX-5 and (R, R)-ZX-5 have high potency in increasing the choroidal blood flow and improving the retinal function recovery. It is hoped that they could be used for the prevention/treatment of ocular blood flow related eye diseases.

OBJECTIVETo examine the differences in the expression of HSP27 and c-kit between benign prostatic hyperplasia (BPH) and prostatic cancer (PCa) tissues and to analyse the relationship between their expression and BPH and PCa, especially the relationship with the occurrence, development, prognosis and treatment of PCa.

METHODSAn immunohistochemical staining (SP method) for HSP27 and c-kit was undertaken on 40 BPH and 40 PCa tissues samples.

RESULTSConsistent patterns of cytoplasmic staining for HSP27 were seen in all sections of tissue from BPH. The glandular epithelium stained very strongly positively and the stroma stained positively. The staining for HSP27 in PCa tissues was located in the cytoplasm of glandular epithelia, but the expression of HSP27 in PCa was higher than BPH (P < 0.05). The staining for c-kit in BPH tissues was located in the cytoplasm of smooth muscle cells, and in PCa tissues was located in epithelial cells. The expression of c-kit in PCa tissues was lower than BPH (P < 0.05). The expression level of both HSP27 and c-kit were decreased with the development of grade of PCa (P < 0.05); HSP27 was increased with the development of clinical stage of PCa (P < 0.05 ); c-kit was decreased with the development of clinical stage of PCa (P < 0.05).

CONCLUSIONThe expression level of HSP27 and c-kit was highly correlated with the process of the development from BPH to PCa, and also correlated with tumor grades and stages. The expression of HSP27 and c-kit may be used as an important pathological index and may be helpful for the treatment of PCa.

OBJECTIVETo study the effect of methylene blue on the growth and acid production of Streptococcus mutans, and the effect of methylene blue on acid production metabolism in plaque glycolysis model (i-PGM) in vitro, and investigate the practicability of methylene blue as a new kind of dental caries prevention agent.

METHODSNephelometer method was used to measure OD value of Streptococcus mutans culture fluid in the different incubation conditions. The kinds and quantities of acid produced by Streptococcus mutans in the different incubation conditions were measured with gas chromatography. pH values of glycolysis buffer media of i-PGM in the different treatment conditions were measured by ORION electrode.

RESULTS(1) The OD value of Streptococcus mutans treated by methylene blue was lower than that by normal saline, and there was significant statistical difference between them. (2) The kinds of acid in three different culture fluid were same, but the total quantities of acid were significantly different among three different culture fluid, in which the total quantities of acid of culture fluids treated by glucose was the greatest, and treated by methylene blue was the lest. (3) The pH value of i-PGM treated by methylene blue was significantly different compared with negative control group, but was not significantly different compared with positive control group.

CONCLUSIONMethylene blue can inhibit the growth and acid production metabolism of Streptococcus matans and acid production metabolism of i-PGM.

OBJECTIVE: To explore the relationship between the time-dependent level changes of microRNA and 18S rRNA and the different postmortem interval (PMI) in rat cardiac muscle. METHODS: SD rats were sacrificed by cervical dislocation and placed at ambient temperature 25 degrees C with a humidity of 50%. Total RNA was extracted from the rat cardiac muscle at different time points after death. The levels of miR-1-2 and 18S rRNA were examined using real-time PCR in rat cardiac muscle. The results were expressed by cycle threshold (Ct) value to explore relationship between PMI and Ct value, and the regression functions were established to estimate PMI. RESULTS: The miR-1-2 level in rat myocardial tissue showed no significant changes within 120 h after death, and then began to decline. The 18S rRNA level increased gradually within 96 h after death, and then declined slowly. The nonlinear relationships were established between Ct value (18S rRNA), deltaCt value (difference between 18S rRNA and miR-1-2) and PMI. The R2 of conics fitting were 0.9487 and 0.8072, respectively. CONCLUSION Ct value of 18S rRNA and deltaCt value present a good correlation with PMI, and can be markers for estimating early PMI.
