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.

This paper reviews the main research progresses of PK of TCM, including integrated PK of multiple effective components of TCM, fingerprint PK of TCM, novel dosage form PK of TCM, polysaccharide PK of TCM and drug interactions of TCM; and further sets up the prospects.

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 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.

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.

The aticle briefly introduced the working principle and clinical applicability of Coblation. The application of Coblation promoted the improvement of traditional surgery and the generation of new operation, it is the most important to hold the indication of the operation strictly. This review summarized that and discussed the advantages and the notes of Coblation in operations of the pharynx and larynx.

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.

Objective To investigate clinical effect of recombinant human growth hormone (rhGH)for inter-venting central precocious puberty in children,to provide reference for clinical treatment.Methods 80 patients with growth deceleration slows CCP were selected,when height growth rate below 4cm/year,40 patients on the basis of joint GnRHa used rhGH treatment were selected as the observation group,and the remaining 40 patients refused to use rhGH,continued to use of GnRHa treatment were selected as the control group.After treatment predicted height,height,bone age,growth rate and other indicators were compared.Results In observation group,the actual height Ht, predicted height PAH,the growth rate Gv,serum insulin -like growth factor -1 (IGF -1 )after treatment were (1 44.48 ±6.59)cm,(1 54.94 ±4.52)cm,(4.43 ±0.64)cm/6months,(1 32.25 ±8.84)ng/mL,compared to before treatment,the differences were statistically significant (t =6.548,P <0.01 ;t =5.734,P <0.01 ;t =28.869,P <0.01 ;t =20.65,P <0.01 ),compared with the control group,the differences were significant (t =3.943,P <0.01 ;t =4.759,P <0.01 ;t =28.247,P <0.01 ;t =20.882,P <0.01 ),there were no differences in other indices;hor-mones FSH,LH and other indicators of the two groups before and after treatment,and blood sugar,thyroid indicators showed no abnormality.Conclusion Recombinant human growth hormone in the treatment of central precocious puberty deceleration in children does not increase bone age,which will help improve the growth rate and predicted height,which worthy of clinical application.

OBJECTIVE To study the antibacterial activity of pazufloxacin in vitro against bacteria isolated from(patients) with respiratory and urinary tract infection,compared with levofloxacin,ciprofloxacin,cefuroxime and(cefotaxime) to provide guideline for clinical application.METHODS The infected bacteria were identified by the(fully) automatic VITEK system.The susceptibility test was determined by MIC method and K-B disk diffusion method respectively.RESULTS The sensitivity of most Gram-negative bacteria to pazufloxacin was basically the same to levofloxacin,cefotaxime, etc.However,the sensitivity of Pseudomonas and Acinetobacter to(pazufloxacin) was higher than to other four antibiotics;the sensitivity of Gram-positive cocci,particularly(Streptococcus) to(pazufloxacin) was obviously lower than cephalosporins and no better than other quinolones.(CONCLUSIONS) The antibacterial activity of pazufloxacin in vitro against the bacteria isolated from patients with(respiratory) and urinary tract infection is comparatively strong,especially in the urinary system.Pazufloxacin has an excellent broad-(spectrum) and strong antibacterial activity.However,the antibacterial activity against Gram-positive cocci is(expected) to promote.
