1.Study on extraction techniques of dietary fiber from Undaria pinnatifida
Chinese Journal of Marine Drugs 2001;0(05):-
Objective To extract dietary fiber from Udaria pinnatifida by using enzymatic-chemical extraction method.Methods All the factors that affect the extraction rate are enzyme content,enzymolysis temperature,enzymolysis time,Na2CO3concentration,Na2CO3extraction temperature,Na2CO3content and extraction time.They were tested with orthogonal experiment.Results The optimal conditions for extraction were determined as follows:the material was hydrolyzed at 50℃ for 1.5h with protease and cellulase mixed at the ratio of 30∶1,followed by the extraction at 65℃ for 3h with 30 volumes of 1% Na2CO3 solution.Under these conditions,the extraction rate could be as high as 12.65%with the color near light yellow.It could be used as additive source of dietary fiber for functional foods.Conclusion The optimum conditions for extraction dietary fiber were established.

Objective To observe the diagnostic value of telomerase,VEGF,CD44_ V6 ,MMP_2,MMP_9and their combined examination in distinguishing malignant pleural effusion from benign one.Methods Sixty patients with pleural effusions were observed,thirty of them sufferring from malignant pleural effusion and thirty of them sufferring from benign one.The expression of telomerase,CD44_ V6 ,VEGF,MMP_2,MMP_9were tested in the pleural effusion by RT-PCR and ELISA technique.The sensitivity and the specificity of each examination method were calculated,in order to find out appropriate combination.Results As single-item detection,the diagnosetic value of VEGF was the best,the cutoff of VEGF was 181.1pg/ml,the sensitivity of VEGF examination was 90.0%,and the specificity was 86.7%.The sensitivity and the specificity of combined examination VEGF+CD44_ V6 and VEGF+MMP_2 were the best,the sensitivity of VEGF+CD44_ V6 was 83.3%,and the specificity was 90.0%.The sensitivity of VEGF+MMP_2 was 80.0% and the specificity was 93.3%.Conclusion The level of telomerase,VEGF,CD44_ V6 ,MMP_2,MMP_9in malignant pleural effusion is clearly higher than that in benign pleural one,the difference having significant statistic meaning.VEGF has higher sensitivity and specificity .Of combined examination,VEGF+CD44_ V6 and VEGF+MMP_2 have higher sensitivity and specificity.

To investigate a huge family with autosomal dominant hereditary non syndromic hearing loss. In this family, sixty six of 113 family members and 8 spouses have been conducted physical examination, pure tone audiometry, immittance testing and auditory brainstem response testing (ABR). The results indicated that 37 of 66 tested family members have sensorineural hearing loss in various degrees. No associated visible abnormalities in other systems were found in this family. The mode of inheritance of this family should be autosomal dominant according to its pedigree. The full collections of both blood samples and physiological hearing assessments of this family have provided the solid basis for future study on identifying disease causing gene.

Objective To avoid complicated wiring, a ward calling system based on wireless protocol is studied. Methods The system adopted ZigBee protocol, composed of calling console as network coordinator, bed-extensions as terminals and network routers in each ward. Results After initial configuration, the system could ring an alarm and gave the patient's bed number and ward number when patients called. Also it provided the automated network faults detection system. Conclusion The system is characterized with convenient installation, high intelligence and easy expansibility, and accords with the trend of technology.

Objective To evaluate the tension-free herniorrhaphy for groin hernia with defect of the entire posterior wall. Methods Fifty-four patients underwent tension-free repair for groin hernia with defect of posterior wall of the groin canal by one of two kinds of prosthesis, Bard Mesh PerFix Plug in 8 cases, Bard Mash in 2 cases and Gore-Tex Micromesh in 44 cases, under epidural anesthesia. Results Inguinal groin hernia of entire posterior wall defect was diagnosed when the defect of the posterior wall was larger than 4 cm in length. Operations were all successful in patients with pimary hernia and recurrent hernia. The mean postoperative follow up was 12.8 months with no recurrence. Conclusions The two tension-free herniorrhaphies for this type of groin hernia were safe and effective.

In this study, the effects of blood glucose and blood pressure on the compliance of large and small arteries were investigated. The results showed that arterial compliances of both large and small arteries were decreased in patients with diabetes mellitus. In non-diabetic patients with well controlled blood pressure, the compliance of small arteries was markedly improved. These results suggested that both blood glucose and blood pressure affected arterial compliance.
