Comparative analysis of characteristic of species and esterase-isoenzyme of isolates of Polyporus umbel-latus from different regions were processed. The results indicated that isolates of Jizhaoling ( Z) and Zhushiling (ZJ) have significant differences in characteristic, and enzymatic band types of the two species also have significant differences. The homology at genetics between the two isolates is 0% , and consanguinity between the two i-solates is the farthest.

Objective To evaluate the value of adenosine tissue Doppler stress eehoeardiography on ischemic myocardium.Methods Routine dosage (140 μg· kg-1 · min-1 IV for 6 min) adenosine stress echocardiography was performed on 40 patients with chest pain for diagnosis of coronary artery disease (CAD).The images of left ventricular myocardial motion were acquired by tissue Doppler imaging (TDI)based on traditional 2D stress ochocardiography before and 3 min,6 rain after adenosine stress (GE Vivid 7,USA).The myocardial velocity,strain and strain rate in 16 segments were offline measured and analyzed on ECHOPAC software.The results were compared with that of coronary angiography (CAG).Results CAG identified 18 CAD and 22 non-CAD patients with 159 ischemie segments and 465 non-ischemic segments.Adenosine significantly increased the systolic velocity (Sm),early diastolic velocity (Em),late diastolic velocity (Am),peak systolic strain (Smax),systolic strain rate (SRs),early diastolic strain rate (SRe)and late diastolic strain rate (SRa) both iachemic and non-ischemic segments (all P<0.05).The baseline Sm and Em in isehemic segments were significant lower than non-ischemic segments [(3.16±1.20) cm/svs (4.03+1.27) cm/s,P<0.01;(3.75±1.67) cm/s vs (4.66±1.70) orals,P<0.05].At peak stress the differences in Sm and Em were mere significant [(3.98±1.63) cm/s vs (5.07±1.52) cm/s;(4.51±2.32) cm/s vs (6.52±2.56) cm/s;P<0.01].The reductions on Smax and Se were more significant in isehemic segments compared those in non-isehemic segments (16.91% ±3.35% vs 19.56%±5.47%,P<0.01 and 9.53%±2.89% vs 13.06% ±4.63%,P<0.001).The biggest area under curve (AUG) in peak stress was seen in Se by ROC curve analysis (AUG=0.740,with sensitivity 67%and specificity 83%).Conclusion Parameters derived from TDI offer reliable and accurate information on ischemic myocardium during adenosine stress echocardiography.

OBJECTIVETo analyze the clinical features, diagnosis, treatment, and prognosis of epithelioid sarcoma (ES).
METHODSThe clinical data of 13 cases with epithelioid sarcoma in the Tianjin Medical University Cancer Institute and Hospital from March 1995 to December 2009 were collected and analyzed. There were 10 males and 3 females in the group, with an average age of 41.5 years (range: 13 to 68 years). Nine patients had classic ES and 4 had proximal-type ES. Surgery was the mainstay of treatment. After the operation, four patients received radiotherapy, five received chemotherapy, and one received chemoradiotherapy.
RESULTSOf the 13 cases, only 1 had multi-locus lesion. The average tumor size was (6.07 ± 1.34) cm. The lymph node involvement was found in 46.2% of the patients. Local and distant failure occurred in 50% and 30% patients, respectively. The most common site for dissemination was the lung. Four cases died within 3 years after initial operation. The 1-, 2-, 5-, 10-year overall survival rates of the 11 cases were 72.7%, 54.5%, 27.3% and 9.1%, respectively, with a median survival time of 27 months.
CONCLUSIONSEpithelioid sarcoma is a rare disease. The prognosis for patients with epithelioid sarcoma is poor because of a high propensity for local recurrence, lymph node metastases, and/or distant metastases. The definite diagnosis depends mainly on the pathologic examination. Wide surgical excision is the mainstay treatment, and radiation and chemotherapy have been used occasionally as adjuvant therapy but have had limited success.

OBJECTIVETo compare the expression of CCL28 in minor and major salivary glands and clarify the role it plays in IgA secreting by minor salivary glands in oral cavity.
METHODSLabial gland and parotid samples were analyzed with real-time fluorescent quantitative PCR assay for CCL28 mRNA. Rank-sum test was used for data analysis using SPSS 10.0 software package.
RESULTSCCL28 mRNA was abundantly expressed in labial glands of healthy adults. Its expression was higher than that in parotids (P<0.01).
CONCLUSIONThe results of this article suggest that the expression level of CCL28 in labial glands is remarkably higher than that in parotids, which reminds us that the high concentration of IgA in minor salivary glands may be associated with their high expression of CCL28.

OBJECTIVETo detect the changes of the expression of Bax and Bcl-2 gene in the denervated testis, and to explore the possible mechanisms underlying the apoptosis of germ cells induced by testicular denervation at the genetic translation level.
METHODSEighteen mature SD rats (350-375 g) were equally divided into 3 groups: a sham operation group( SO) , a superior spermatic nerve group (SSN) and an inferior spermatic nerve group (ISN) , and the latter two received bilateral surgical removal of the superior spermatic nerve and the inferior spermatic nerve, respectively. The animals were killed I month after the operation. ISH SP-method was used to detect the expression of Bax and Bcl-2 protein.
RESULTSSignificant up-regulation of Bax protein was detected in both the treatment groups 1 month after surgery( P <0. 05) , and the level of Bcl-2 protein remained unchanged.
CONCLUSIONBax gene is involved in the apoptosis of germ cells induced by testicular denervation.

OBJECTIVETo evaluate the role of spermatic nerves in the regulation of spermatogenesis.
METHODSFifty-four mature SD male rats (350-375 g) were randomized into a sham operation group (SO) and three experiment groups, and the latter underwent bilateral surgical removal of the superior spermatic nerve (SSN) or/and the inferior spermatic nerve (ISN). The animals were killed 1 month and 2 months after the operation. HE stain was used to observe spermatogenesis. Transmission electron microscopy and terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling (TUNEL) were employed to detect apoptosis.
RESULTSImpaired spermatogenesis was observed 2 months after the operation, with only Sertoli cells and a few spermatogonia remaining in the regressed tubules in all the treatment groups. The abnormal tubules in the SSN, ISN and SSN + ISN denervated testes accounted for (13.25 +/- 2.03)%, (11.0 +/- 4.36)% and (34.17 +/- 3.78)% respectively. Chromosome condensation and fragmentation in the germ cells were observed under the electron transmission microscope in all the denervated testes. TUNEL showed the spermatogonia and Leydig cells to be apoptotic in all the denervated testes and the incidence of the apoptotic cells in the SSN + ISN denervated testes was significantly higher than in the SSN or ISN denervated ones.
CONCLUSIONSpermatic nerves play an important role in spermatogenesis.

OBJECTIVE:
To explore the correlation between the interleukin-17 (IL-17) level of peripheral blood and aggression of bipolar mania.
METHODS:
Thirty-six patients of bipolar mania were selected as experimental group by DSM-IV-TR and received treatment with quetiapine and lithium. Thirty-six healthy volunteers with similar age and gender were selected as control group. The level of IL-17 at baseline in each group and the level of IL-17 in the experimental group after treatment for 2, 4 and 8 weeks were detected by ELISA.
RESULTS:
The level of IL-17 in experimental group at baseline, after treatment for 2 and 4 weeks were all significantly higher than that in control group. After 8 weeks treatment, there was no significant difference between the two groups (P > 0.05). After 2, 4 and 8 weeks treatment, the total score and aggression score of Young Mania Rating Score (YMRS) were significantly lower than the baseline level (P < 0.05). In experimental group, the level of IL-17 was positively correlated with the two scores of YMRS at baseline (P < 0.05).
CONCLUSION
Bipolar mania may be related to the up-regulation of IL-17. The level of IL-17 is related to the severity of manic symptoms at baseline, especially aggression symptom.
