Inhibitory effects of the O - ( 1 - ethoxvl - butyl ) berbarmine (EBB) on cultured fibroblast was studied by observating calmodulin (CaM ) content of cultured fibroblast with ELISA and DNA content at each phase of cell cycle with flow - cvtometerv. The CaM con-tent in the test group . compared to control . decreased markedly and DNA content increased significantly in the G0+Gi phase but reduced in the S phase. These results suggested that inhibitory mechanism of EBB on fibroblast proliferation may be closely related to CaM decrease in cells.

Objective To evaluate the clinical value between peritoneal lavage cytology (PLC) and prognosis of gastric cancer. Methods The peritoneal lavage fluid of 60 gastric cancer patients and 12 noncancer patients were collected,different methods were used to examine the exfoliated cancer cells,and relationships between positive results and relative clinico-pathological parameters were evaluated.Results The positive rate of PLC was 31.8%,and was positively correlated with the degree of histologic differentiation of gastric cancer (P0.05). The postoperative one-year recurrence and survival rates of the positive and negative groups were significantly different(P

Objective To observe the value of the high frequency color Doppler uItrasonography in emergency operation of flexor tendon injuries in the hand.Methods Totally 21 patients of flexor tendon injuries in the hand underwent surgical exploration with high frequency probe.The extent of the tendon injuries,the retracted parts of the ruptured tendon and the blood supply were observed.Results The extent of the tendon injuries,the poison of broken ends were clearly distinguished with high frequency probe.The continuous tendon fibrous of layered high echo and sheath thin layer low echo complete broke and replaced with low or no echo.Conclusion Intraoperative uhrasonography of flexor tendon iniuries is important tO shorten operation time,reduce the injury of surrounding tissues,relieve local adhesion and ensure vascular recanalization after operation.
