With development of bio-technique, more and more proteins were applied as clinical approaches. However, the protein homogeneity, especially the N-glycosylation limited the further research and application of these protein drugs. The analysis method for N-glycans is believed to be critical in protein drugs development. To enhance the N-glycans isolation efficiency and accelerate the pretreatment, a new strategy was built on ultrafiltration-devices. New methods increased the isolation efficiency of N-glycans containing N-acetylglucosa mine with 10%-20%. The degrading of N-glycans containing sialic acids was also minimized with this method. 20%-100% more N-glycans with sialic acids were isolated. The pretreatment was finished within 30 min. Coupled with HPLC-HRMS, an effective and reliable strategy designed for protein drugs N-glycans analysis were developed.

Medical service system integration follows the logic of system innovation and development.Case studies of the UK,the USA and Australia found that medical delivery system integration is the product of a series of mixed factors.Health care financing and payment mechanism reform,physician team building,stair-cased movement to grassroots of healthcare service,shared clinical norms utilization as well as its gradual development constitute the general logic of such an integration.In the evolution process,the check and balance between the government and market,equity and efficiency have been affecting the integration process all the way.In light of these logics,China should speed up its transform of the integration concept,improve the integration elements,and strengthen the guidance of integration principles during its integration of the medical service integration.

Stilbene glucoside is one of major active constitutions in Polygoni Multiflori Radix. Stilbene glucoside contributed markedly to resisting caducity, protecting nerve, reducing serum lipids, and protecting liver and antitumor activity. The extraction and purification technology is the key issue to obtain stilbene glucoside. Through research, extraction and purification technology has made a certain progress. The stilbene glycoside could be extracted by water boiling, diacolation, and backflow; then it could be purified by the method of chromatography, recrystallization, and extraction. In this article, the technologies in extracting and purifying stilbene glucoside were reviewed, and the prospect of stilbene glucoside preparation was discussed to lay the foundation for further research and application.

Objective To investigate the blood pressure status of preschool children in urban areas of Qingdao, and to determine the relationship between obesity and blood pressure in preschool children. Methods A stratified cluster sampling method was used to select a total of 13 kindergartens in urban districts of Qingdao. Height, weight, waist circumference, hip circumference and blood pressure of children in three classes were measured. Body mass index (BMI), waist to hip ratio and waist to height ratio were calculated and the relationship between obesity and blood pressure was analyzed. Results The mean values of systolic and diastolic blood pressure in preschool children in urban areas of Qingdao were (95.52±7.66) and (62.78±6.52) mmHg, respectively.The detection rate of hypertension in preschool children was 13.50%. The SBP and DBP were positively correlated with BMI, waist circumference, hip circumference and waist to height ratio. There was a linear regression relationship between body mass index and age and blood pressure. The risk of hypertension in overweight and obese children was 5.191 and 2.824 times of normal body weight, respectively. Conclusions The prevalence of hypertension in preschool children in Qingdao urban areas is high.Overweight and obesity are risk factors for elevated blood pressure.Therefore, while preventing preschool children from obesity, preschool children's blood pressure monitoring and blood pressure monitoring and early intervention of hypertension of preschool children should be implemented.

Objective To investigate the clinical features and LRRK2 gene mutation in patients with autosomal dominant familial Parkinson's disease (PD). Methods The clinical features of 16 autosomal dominant familial PD probands were analyzed in terms of age at onset, onset symptoms, UPDRS scores, response to the levodopa treatment and drug-induced dyskinesia. The LRRK2 gene exons 5,13,31,32,35,37,41 and 48 of 16 probands were sequenced after polymerase chain reaction. The novel mutation was further screened in 24D sporadic PD patients and 214 controls using PCR-RFLP for the genotypo frequency analysis. Results Clinically, most of 16 probands had late-onset age. Resting tremor (9patients, 56. 25%,t=0.558,P=0.679)and bradykinesia (9 patients,56.25%,t=0.369,P=0.454)were common onset symptoms followed by rigidity(6 patients,37.50%,t=1.324,P=0.735)and postural instability(5 patients,31.25%,t=2.369,P=0.956).Majority of them had good response to levedopa treatment and rare occurrence of drug-induced dyskinesia. Among the 16 autosomal dominant familial PD probands,6 variants were identified:c.457 T＞C(Leu153Leu),c.1432 G＞T(Asp478Tyr),c.5457 T＞C(Gly1819Gly),c.7153 G＞A(Gly2385Arg),IVS31+28 T＞G and IVS37+162 T＞C. The c.1432G＞T(Asp478Tyr)variant was a novel mutation and it was not detected in 240 sporadic PD patients and 214 controls. The reported mutations associated with the PD, such as Arg1441 Cys/Gly/His, Arg1514Gln, Tyr1699Cys, Ile2012Thr, Gly2019Ser and Ile2020Thr,were not found in our study. Conclusions The autosomal dominant familial PD patients present with classical symptoms of PD and bear the LRRK2 variantsAsp478Tyr and Gly2385Arg.

The fragmentation pathways of five estrogens (estradiol, estrone, equilin sulfate, 17 a-dihydroequilin sulfate and equilenin sulfate) have been studied with high resolution and high mass accuracy using electrospray ionization quadrupole time-of-flight mass spectrometry (ESI-Q-TOF/MS) in the negative ion mode. Molecular weights were obtained from [M-H](-) ions in the product ion spectra. The results indicate that the five structurally similar estrogens have similar fragmentation pathways. Using their stable isotope forms as internal reference compounds, the accurate mass and composition of the fragment ions were determined. During collision-induced dissociation (CID), cleavage is initiated by loss of oxygen atoms from carbon-17, after which D and C rings cleave sequentially and rearrange to finally form stable conjugate structures with highly abundant characteristic fragment ions at m/z 183 (accompanied by m/z 181), m/z 169 and m/z 145 (accompanied by m/z 143). Understanding these characteristic fragmentation pathways of estrogens will be helpful in identifying the structures of steroid hormones in general.

Objective To investigate the expression of steroidogenic factor 1 ( SF-1 ) in eutopic endometrium,ovarian endometriosis (EM) and adenomyosis.Methods From Jan.2008 to Dec.2010,30 patients with both ovarian endometriotic cysts and adenomyosis underwent hysterectomy,cystectomy or adenxectomy in Peking University First Hospital.The combination of ovarian EM and denomyosis were confirmed in 17 cases.In the mean time,endometria form 10 patients with cervical intraepithelial neoplasm ( CIN ) Ⅲ underwent hysterectomy were selected as controls.The expression of SF-l in eutopic endometrium,ovarian EM and adenomyosis was detected by immunohistochemistry staining.Results No immunoreactivity of SF-l was observed glandular cell and stromal cell in eutopic endometrium of both groups.14/17 of positive rate of SF-l were observed in lesions of ovarian endometriosis.SF-l protein was not expressed in the endometrial glandular cells of ovarian EM and in adenomyosis foci.Conclusion The differences of SF-l expression in ovarian endometrioma and adenomyosis foci might mediate the development of the disease.

OBJECTIVE:To investigate the preventive and therapeutic effect of Shuganning injection on alcoholic liver fibrosis (ALF) in model rats,and provide experimental basis for its clinical application for alcoholic liver disease. METHODS:50 rats were enrolled and intraperitoneally given mixed liquid of 60% alcohol-corn oil-pyrazole to reduce ALF model. Another 10 rats were enrolled and intraperitoneally given normal saline,as normal control group. After 16 weeks,survived model rats(n=40)were ran-domly divided into model group,positive control group(Anluo huaxian pill 0.75 g/kg,ig),Shuganning injection high-dose,medi-um-dose,low-dose groups(4.8,2.4,1.2 mL/kg,ip),8 in each group. Normal control group and model group were intraperitone-ally injected equal volume of normal saline (5 mL/kg),administration groups were given relevant medicines,once a day,for 8 weeks;and modeling was contiuously conducted at the same time. After administration,body mass of rats was weighed,and the levels of liver function indexes [aspartate aminotransferase(AST),alanine aminotransferase(ALT)] and liver fibrosis indexes [hyal-uronic acid(HA),laminin(LN),type Ⅲ procollagen(PⅢNP),type Ⅳ collagen(Ⅳ-C)] in serum of rats were detected. Liver index of rats was determined and pathological changes of liver tissue were observed. RESULTS:Compared with normal control group,body mass of rats in model group was significantly decreased(P<0.05);liver index,and liver function index,liver fibro-sis index levels in serum were significantly increased (P<0.05 or P<0.01). Liver tissue showed steatosis,hepatocyte vacuoliza-tion,a large number of fibrous tissue deposition around portal areas and other pathological changes. Compared with model group,above-mentioned changes were improved significantly in administration groups (P<0.05 or P<0.01). CONCLUSIONS:Shugan-ning injection can obviously improve liver tissue damage of model rats with ALF,showing certain preventive and therapeutic effect on alcoholic liver disease.
