A method of observation, examination and record was introduced in this paper, which was applicable for microorganism materials (example : bacteria, yeast moulds), animal and plant materials (example: animal tissue, flowers), bio-masromolecule (example: starch), industrial crystals, metallograph tests and general physics tests, through the hyphae, spores, spore sacs, expanding hyphae in fermentation and riboflavin crystals of E. ashbyii T30 (a riboflavin high-yield strain) had been observed.

Objective To investigate the relationship between the expression of laminin and laminin-receptor in pulmonary carcinoma and cancer metastasis as well as prognosis.Methods Techniques of immune histochemistry were used.Results The higher the pathological grade of pulmonary carcinoma was, the higher the level of expression of laminin was. There were significant differences betweenⅠgrade group andⅡgrade group and Ⅲ grade group and Ⅳ grade group. The expression of laminin was also related to lymph node metastasis (P

Objective To research the expression and clinical significance of SALL 4 gene in cervical cancer .Methods The ex-pression of SALL4 in 56 samples of cervical cancer and 35 samples of normal cervical tissues was detected by immunohistochemistry and RT-PCR ,and its relationship with the clinicopathological characteristics of cervical cancer was analyzed .Results The expres-sion of SALL4 mRNA was 2 .56 ± 0 .22 in cervical cancer tissues ,which was significantly higher than 0 .38 ± 0 .03 in the normal cer-vical tissues .the difference between them had statistical significance(t=58 .1 ,P<0 .01);the positive expression rate of SALL4 pro-tein was 80 .4% (45/56) in cervical cancer ,which was significantly higher than 11 .4% (4/35) in the normal cervical tissues (χ2 =41 .177 ,P<0 .01) .The positive expression of SALL4 in the cervical cancer tissues was correlated with the differentiation status of tumor ,which in the middle and high differentiation groups was lower than that in the low differentiation group (χ2 =4 .226 ,P=0 .039) ,but had no correlation with age ,International Federation of Gynecology and Obstetrics (FIGO) stage ,tumor size ,pathologi-cal type and lymph node metastasis(P>0 .05) .Conclusion SALL4 is highly expressed in the cervical cancer tissues and correlated with the tumor differentiation ,which might play an important role in the occurrence and development of cervical cancer .

Objective To measure the temperature sensation threshold of trunk skin in healthy adults. Methods The threshold of cold sensation, warm sensation, cold pain sensation and heat pain sensation of trunk skin key points (T3, T7 and T11) were measured with Thermal Sensory Analyzer in 123 healthy adults. Results The thresholds of cold, warm, cold pain and heat pain sensations were obtained. The standard deviation of cold and warm threshold was less than that of heat pain. The range of cold sensation threshold was the largest. The heat pain sensation threshold increased with segmental declining and the sensation threshold increased with age. Conclusion Normal reference value should be established variously with the segment and age. The threshold of cold, warm varies less, while the threshold of cold pain and heat pain varies too much.
