This study was designed for the evaluation of the mean proportions and range of individual difference of muscle fiber types in human Gastrocneminus, Soleus, Peroneus longus and Tibialis anterior muscles, respectively. Flash-frozen muscle sections obtained from 15 cadavers were stained for H&E, trichrome, PAS, regular & reversed myosin ATPase, succinic dehydrogenase (SDH), acid phosphatase (Ac-Pase) and alkaline phosphatase (Alk-Pase). The results obtained were as follows. 1) Differentiation of muscle fiber types was not evident in H&E and trichrome stained specimen. Three types of muscle fibers were, however, evident in PAS-stained sections according to the degree of positivity in observed skeletal muscles. 2) Two fiber types (Types I and II) were only differentiated and the predominant muscle fiber type was type I by regular myosin ATPase reaction in Gastrocnemius, Soleus, Peroneus longus and Tibialis anterior muscles. 3) Three muscle fiber types (Type I, IIa and IIb) were, however, differentiated and the predominant muscle fiber type was type IIa, contrary to patterns of regular myosin ATPase in skeletal muscles except for Soleus muscle by reversed myosin ATPase stains. Only two muscle fiber types (Type I and II) and predominant type I fibers were shown in Soleus muscle. 4) SDH stains showed three types of muscle fiber except Soleus muscle. The mean proportions(%) of type 1 fibers were 48.0% in Gastrocnemius, 62.3% in Soleus, 40.8% in Peroneus longus, and 39.8% in Tibialis anterior muscles, respectively. 5) The mean proportions (%) of muscle fiber types in human skeletal muscles were markedly different, according to individuals and various enzyme histochemical stains. 6) The size of muscle fibers was relatevely small in type I fibers compared with type IIb. 7) Evaluation for the combination patterns of various enzyme histochemical activities showed that the common muscle fiber types (Type I, IIa and IIb) were markedly reduced in the mean proportions and unusual rare muscle fibers predominant. This predominance of unusual muscle fiber types and marked discrepancy in muscle fiber types between regular and reversed myosin ATPase seemed to be ascribed to decreased muscle enzyme activities following postmortem period.

Objective To detect the excision repair cross-complementing gene 1 (ERCC1) and thymidylate of the acid synthase (TS) in non-small cell lung cancer (NSCLC) and its adjacent tissue,and investigate the relationship of the expression of ERCC1 and TS with the clinical characteristics of NSCLC and prognosis for NSCLC individual therapy to provide experimental basis.Methods The protein expression levels of ERCC1 and TS in 50 cases of postoperative NSCLC cancer and adjacent tissue were detected by immunohistochemical method and the relationship among the expression of ERCC1,TS,and overall survival of patients with NSCLC Phase (OS),disease progression time (TTP),the median OS,and median TTP was analyzed.Results (1)There was an obvious difference between the expression of ERCC1,TS in cancer and paraneoplastic tissue of NSCLC,which had statistically significance (64.00％ vs 20.00％,x2 =19.87,P ＜ 0.01 ;48.00％ vs 24.00％,x2 =6.25,P ＜ 0.05) ; (2)The continued investigation in the patients who received postoperative cisplatin or carboplatin chemotherapy showed that the 0S of negative expression of ERCC1 was significantly longer than the positive one (19.10 vs 10.00 months;x2 =8.133,P =0.002),so was median TTP (15.30 vs 9.00 months; x2 =7.410,P =0.003).The median 0S of the negative expression of TS,was significantly longer than the positive one (17.80 vs 11.00 months,x2 =7.001,P =0.008),so was median TTP (11.40 vs 6.80 months; x2 =5.884,P =0.026).Conclusions ERCC1 and TS protein may become sensitive predictors of platinum chemosensitivity for NSCLC patients ; the detection of combined with ERCC1 and TS would contribute to the selection of individualized treatment programs for NSCLC.

Objective To evaluate the security and effect of combination of adjuvant hormonal thera- py and brachytherapy for localized prostate cancer.Methods 22 patients with T1-T2c prostate cancer were treated with transperineal ultrasound-guide 125I seeds prostate implantation and adjuvant hormonal therapy for 4～7 months.The hormonal therapy include 2-4 months before brachytherapy and 1～4 months after brachytherapy.Results The median operation time was ninety minutes,the median number of ~(125)I seeds used was 56.The follow up time was 12～48 months,the cases of PSA
