AIM:To establish a liquid chromatography method for determining the monosaccharide composition of human lipoproteins, and to investigate the differences between diabetic patients and healthy participants.METHODS:Liquid chromatography with pre-column derivatization was used to determine the neutral and basic monosaccharides, and liquid chromatography tandem mass spectrometry was applied to quantify N-acetylneuraminic acid content.RESULTS:The contents of mannose, glucosamine, N-acetylglucosamine, glucose, galactose and N-acetylneuraminic acid in high-density lipoprotein from healthy participants and diabetic patients were (5.88 ±0.94),(16.49 ±4.11),(1.31 ±0.33), (0.87 ±0.16), (7.18 ±1.64), (2.14 ±0.12) mmol/(g protein) and (8.68 ±0.39), (24.73 ±5.50), (1.91 ±0.54), (1.23 ±0.35), (9.73 ±2.85), (3.53 ±0.27) mmol/(g protein), respectively.The contents of mannose, glu-cosamine,N-acetylglucosamine, glucose, galactose and N-acetylneuraminic acid in low-density lipoprotein from healthy par-ticipants and diabetic patients were ( 29.20 ±3.57 ) , ( 50.77 ±4.72 ) , ( 5.28 ±0.64 ) , ( 10.06 ±1.37 ) , ( 28.44 ± 3.96),(6.86 ±0.11) mmol/(g protein) and (30.08 ±3.78), (38.52 ±6.38), (3.79 ±0.78), (7.63 ±1.50), (20.05 ±2.63), (6.45 ±0.18) mmol/(g protein), respectively.The contents of mannose, glucosamine, glucose, ga-lactose and N-acetylneuraminic acid in very-low-density lipoprotein from healthy participants and diabetic patients were (91.21 ±4.12), (27.05 ±2.34), (4 230.95 ±15.83), (43.40 ±3.75), (2.95 ±0.24) mmol/(g protein) and (82.40 ±0.51), (30.16 ±0.32), (4 722.73 ±93.27), (34.05 ±2.81), (4.42 ±0.15) mmol/(g protein), respec-tively.CONCLUSION:Liquid chromatography with pre-column derivatization is suitable for the neutral and basic mono-saccharide analysis in human lipoproteins, and the glycosylation of lipoproteins in diabetic patients are significantly changed compared with the healthy controls.

AIM:To investigate the roles of maspin in the biological behaviors of non-small-cell lung cancer A549 cells.METHODS:Full-length coding region of maspin was amplified by PCR from human normal breast tissue and cloned into MSCV vector .Virus supernatants was produced by Phoenix A packaging system , and target cell line was infec-ted with the virus supernatants .The transfected cells were screened with puromycin .The cell line with maspin over-expres-sion was identified by real-time PCR and Western blot.Cell growth, migration and invasion were investigated by xCelli-gence system .RESULTS:Maspin over-expression vector was successfully constructed .The cell line with maspin over-ex-pression was established .No difference of the growth between A 549-control cells and A549-maspin cells was observed .The migration and invasion were quite different between A 549-control cells and A549-maspin cells.The expression level of inte-grin β1 in A549-maspin cells was decreased compared with A 549-control cells .CONCLUSION:Maspin has no effect on the growth of A549 cells.Maspin suppresses the migration and invasion of A 549 cells, in which integrin β1 is involved.

This article describes a method totransfer physiological data through carrier-current communication.The microcontroller measures the data of heartrate and body temperature and sends them through the serial port tothe carrier-current module implementing carrier-current communication.This method can be used totransfer physiological data through short distance less than200meters.

Objective To evaluate the effect of convalescent training on patients after special prosthesis replacement in treatment of giant cell tumors. Methods 20 patients with giant cell tumors were treated with convalescent trainings postoperatively,including trainings of muscle strength,joint movement, balance, noumenal sense and gait and were emphasized for earlier training of active muscle contraction. Results According to Enneking score system of bone and muscle postoperation, the lowest for extremitas superior postoperation score of 5 patiens was 20,the highest was 28, the average was 26.6. 4 patiens score was higher than 24, the good rate was 80.0 %.15 patiens extremitas inferior score was from 14 to 27, the average was 21.5, the good rate was 86.7 %. Conclusion Earlier staged joint functional rehabilitation exercise after special prosthesis replacement in treatment of giant cell tumors could prevent ankylosis,improve adhering of capsule,ligament and other soft tissue,and recover the joint function to maximum.

OBJECTIVE To approach the distribution characteristic and drug resistance status in pathogens from infected urinary tract in Jingshan County and offer the scientific evidence for clinically reasonable use of antibiotics.METHODS Totally 218 strains of pathogens isolated from urinary tract were identified by routine methods according to the National Clinical Laboratory Operation Rules.Drug susceptibility testing was performed by K-B methods recommended by CLSI.RESULTS Among 218 strains of pathogens from infected urinary tract,Escherichia coli accounted for 61.0%,ranking the first and enterococci ranked the second,accounted for 11.5%.Except for 100% sensitivity to vancomycin and teicoplanin in Gram-positive bacteria and to imipenem and meropenem in Gram-negative bacteria,the pathogens from infected urinary tract had been resistant to commonly used antibiotics in some degrees.The detection rate of extended-spectrum beta-lactamases(ESBLs) producers was 32.9%.CONCLUSIONS The drug resistance in pathogens from infected urinary tract is on the rise.We should strengthen monitoring and controlling of it.

Objective To detect the effect of olfactory bulb(OB)lesion on proliferation,migration and differentiation of the neural stem cells(NSCs)in the subventricular zone(SVZ).Methods Forty-two healthy female SD rats were enrolled and randomly divided into normal control group,isotonic saline group and OB lesion at day 3,at weeks 1,2,3 and 4 groups,six rats per group.OB lesion was induced by N-methyl-D-aspartic acid(NMDA)injection.Bromodeoxyuridine(BrdU)was injected intraperitoneally to label NSCs.Immunohistochemical staining was used to detect the proliferation of SVZ NSCs.In addition,another 18 rats were randomly divided into normal control group,isotonic saline group and lesion group,six rats per group.BrdU was injected intraperitoneally one week after OB lesion and then the animals were sacrificed four weeks after BrdU injection to detect the migration and differentiation of NSCs with immunohistochemistry and immunofluorescence.Results Three days after OB lesion,BrdU-positive cells in SVZ began to increase(26.33 ± 2.58,P ＜0.01),reached the maximum at week 1 (35.33 +3.01,P＜0.01)and still sustained a high level at week 4(19.50+ 2.26,P＞0.05).Five weeks after the OB lesion,the rostral migratory-stream(RMS)and the BrdU-positive cells in OB were significantly increased(86.50 + 5.09,P ＜ 0.01)and(52.83 + 3.87,P ＜ 0.01),respectively.By using fluorescence double staining,most of the BrdU-positive cells were co-localized with the neuronal nuclear antigen(Neun),with a portion of BrdU-positive cells expressing the glial fibrillary acidic protein (GFAP).Conclusions OB lesion can improve the proliferation of NSCs in SVZ and migration of NSCs to OB.The newborn cells can differentiate into not only neurons,but also gliocytes and may be involved in lesion repair.

: Acupotome therapy exhibits good efficacy on knee osteoarthritis in clinic. The mechanism based on its dynamic equilibrium theory is that acupotome therapy can restore normal joint stress state by changing the imbalance of mechanical equilibrium around the joint. Furthermore, it can ease inflammation, relieve pain and repair tissue structure so as to achieve its therapeutic effect. This review proposes new thoughts for the etiopathogenisis, pathology and treatment of KOA.
