The ultimate goal of post-genome research is to understand a complete set of proteins in a living organism for their expression pattern and biological function,which is called proteomics.One of the major challenges in proteome research is to study the protein-protein interactions,and the emerging bioinformatics approaches present us tremendous advantages when dealing with protein interaction networking and data analysis.Useful bioinformatics tools include protein-protein interaction network mapping,topology of the network,structure of the module and comparison of the network.The technology advancement in this field brings further understandings to the structure and function of cells at the proteome level,which may eventually lead to the discovery of new drug targets and design methods.This paper attempts to review the current researches on protein-protein interaction with an emphasis on bioinformatics intervention,and also summarizes some widely used methods for network analysis.

Objective: To explore the treatment effect of sticking-needle acupuncture plus tendon-regulating manipulation on pain, swelling and joint dysfunction due to acute ankle sprain.Methods: A total of 80 patients with acute ankle sprain were recruited and divided into a control group and a treatment group according to the random number table method, with 40 patients in each group. Both groups received the same conventional interventions. The control group was treated with additional tendon-regulating manipulation, and the treatment group was treated with tendon-regulating manipulation plus sticking-needle acupuncture. The pain, swelling and joint dysfunction of the ankle were observed in both groups before and after 3 d, 7 d and 14 d of treatment. Results: Before treatment, there was no statistically significant difference in the visual analog scale (VAS) score of pain between the two groups (P>0.05). After treatment, the VAS scores of both groups showed a decreasing trend over time, and the differences within the groups were statistically significant (P<0.05). After 3 d, 7 d and 14 d of treatment, the VAS scores in the treatment group were lower than those in the control group, with statistically significant differences (P<0.05). Before treatment, there was no statistically significant difference in the degree of swelling between the two groups (P>0.05). After treatment, the degrees of swelling in both groups showed a decreasing trend over time, and the differences within the groups were statistically significant (P<0.05). After 3 d and 7 d of treatment, the degrees of swelling in the treatment group were lower than those in the control group, with statistically significant differences (P<0.05). There was no statistical difference in the degree of swelling between the two groups after 14 d of treatment (P>0.05). Before treatment, there was no statistically significant difference in the American Orthopedic Foot Ankle Society (AOFAS) ankle-hindfoot scale score between the two groups (P>0.05). After treatment, the AOFAS ankle-hindfoot scale scores of both groups showed an increasing trend over time, and all the differences within the groups were statistically significant (P<0.05). After 3 d, 7 d and 14 d of treatment, the AOFAS ankle-hindfoot scale scores in the treatment group were higher than those in the control group, with statistically significant differences (P<0.05). Conclusion: Based on the routine intervention, the addition of sticking-needle acupuncture and tendon-regulating manipulation was better in alleviating pain and swelling and improving joint function in patients with acute ankle sprain than the addition of tendon-regulating manipulation alone.

Objective To investigate the expression of vascular endothelial cell growth factor(VEGF) and its upregulation of matrix metalloproteinase-2(MMP-2)activation in synovial fluid of patients with rheumatoid arthritis(RA)as well as its role in the pathogeneses of RA.Mathods Expression of VEGF and receptor KDR in mononuclear cell(MNC)of synovial fluid of RA patients and controls were determined by Western blot;VEGF levels of supernantants from MNC was determined by ELISA;supernantants from KDR~+ MNC of synovial fluid of RA patients collected after incubation in serum-free medium with or without VEGF, their activity of MMP-2 was measured by gelatinolytic zymography;Boyden chamber-matrigel in vitro invasion assay was used to detect the invasive capacity in vitro in KDR~+ MNC of synovial fluid of RA patients incubat- ed with or without VEGF.Results The expressions of VEGF/KDR in MNC of synovial fluid of RA patients were significantly higher than those of controls;the MMP-2 activity and invasive ability of co-cuhured KDR~+ MNC with VEGF was higher than those of without VEGF.Conclusion VEGF upregulates MMP-2 activation and promotes invasion of MNC of synovial fluid of RA patients by interacting with receptor KDR,indicating that VEGF plays an important role in RA pathology.

Objective To provide a practicable method for the complete display and localization of the posterolateral structures (PLS) of the normal knee through MRI study. Methods 30 tibial bone specimens were observed to establish the bony landmark for localizing the knee. In 50 cadaver knees, the angles between lateral tibial plateau and the long axis of the individual structure of PLS were measured. Then the scan methods of the oblique MR images were determined based on above results. The routine and oblique scans of T 1WI were performed in 40 normal knees. The display effect and appearance of the PLS were observed on MRI. Results The lateral tibial plateau was a stable bony landmark for measuring and localizing of the knee. In the 40 normal knees, The fibular collateral ligament could be intactly displayed on 70? posterior coronal oblique images in 34 cases (85%). The popliteus could be better seen on either 45? medial sagittal oblique in 34 cases (85%) or 60? posterior coronal oblique planes in 36 cases (90%). The popliteofibular ligament could be intactly appreciated on both 60? posterior coronal oblique in 32 cases (80%) and 70? lateral sagittal oblique images in 34 cases (85%). Although the arcuate ligament and the fabellofibular ligament could occasionally be seen on routine and oblique images, but the display rate was lower. Conclusion The oblique MR imaging can intactly display the main structures of PLS, and can be useful in diagnosing the injuries in those structures.

OBJCETIVETo investigate the method of separation of culture of bone microvascular endothelial cells (BMECs) of human femoral head in vitro.

METHODSFrom October 2013 to January 2014,15 femoral heads without pathologic change from patients resected during hip replacement were selected involving 2 males and 13 females with a mean age of 71.2 years old ranging from 38 to 92. Cancellous bone in femoral head was bited into broken bone grain and transfered into medium in aseptic contidion. Cells were isolated by the methods of enzymic digestion and density gradient centrifugation,purified by differiential attachment. The characteristics of cells was observed by inverted microscope. vWF and CD31 immunofluorescence analysis was applied for identification of cells.

RESULTSThe number of cells was positively correlated with patients' age after 24 hours in primary culture. The older patients had the less cells numbered. After 4 to 5 days' culture, primary cells appeared short spindle,polygon shaped and cobblestone-like morphology. After 7 to 10 days' culture, primary cells proliferated densely, became fusion, arranged in swirl, and contact inhibition appeared significantly. Immunofluorescence staining revealed the cells were 100% positive for vWF and CD31, and it showed that the cultured cells were BMECs.

CONCLUSIONIt was a simple, steady, effective method with good reproducibility, by which highly purified human BMECs can be obtained.

OBJECTIVESince glucose-6-phosphate dehydrogenase (G6PD) deficiency is the most common hereditary hemolytic erythrocyte enzyme deficiency, most cases have single nucleotide mutations in the coding region, and current test methods for gene mutation have some missed detections, this study aimed to investigate the feasibility of RT-PCR sequencing in the detection of gene mutation in G6PD deficiency.

METHODSAccording to the G6PD/6GPD ratio, 195 children with anemia of unknown cause or who underwent physical examination between August 2013 and July 2014 were classified into G6PD-deficiency group with 130 children (G6PD/6GPD ratio <1.00) and control group with 65 children (G6PD/6GPD ratio≥1.00). The primer design and PCR amplification conditions were optimized, and RT-PCR sequencing was used to analyze the complete coding sequence and verify the genomic DNA sequence in the two groups.

RESULTSIn the G6PD-deficiency group, the detection rate of gene mutation was 100% and 13 missense mutations were detected, including one new mutation. In the control group, no missense mutation was detected in 28 boys; 13 heterozygous missense mutations, 1 homozygous same-sense mutation (C1191T) which had not been reported in China and abroad, and 14 single nucleotide polymorphisms of C1311T were detected in 37 girls. The control group showed a high rate of missed detection of G6PD deficiency (carriers) in the specimens from girls (35%, 13/37).

CONCLUSIONSRT-PCR sequencing has a high detection rate of G6PD gene mutation and a certain value in clinical diagnosis of G6PD deficiency.

OBJECTIVETo explore the feasibility of human leucocyte antigen (HLA) haploidentical related T-cell undepleted allogeneic bone marrow transplantation (Allo-BMT) combined with Chinese medicine for the treatment of leukaemia.

METHODSFour patients with chronic myeloblastic leukemia (CML) and 4 with acute myeloid leukemia (AML) received allo-BMT with graft from 1 - 3 HLA-mismatched related donors. All patients were pre-treated with standardized conditioning regimen consisting of high dose Ara-c, cyclophosphamide (CY) and total body irradiation (TBI) or busulfan. Donors were given G-CSF 250 microg/d for 7 days prior to marrow harvest. To prevent GVHD, besides application of CSA and MTX, ATG 2.5 mg/kg was given everyday for 4 days before transplantation, and MMF 1.0 g per day starting from the 7th day after transplantation. Chinese medicine for replenishing qi and yin and strengthening Pi and Wei was administrated orally after transplantation.

RESULTSSuccessful haematopoietic reconstruction was seen in all patients. The median days for reaching of granulocyte >0.5 X 10(9)/L and platelet > 20 x 10(9)/L were 12 (range 10-14) and 20 (range 18-25) days respectively. GVHD of skin in various grade was seen in 7 patients, among whom only one advanced to grade IV; besides, 2 accompanied with GVHD of gut, one with hemorrhagic cystitis, one died for concurrent infection on the 81st day, and one left hospital of his own accord on the 46th day. The median follow-up duration was 18 (range 2-32) months, during this period six patients were alive in a disease-free situation.

CONCLUSIONCombined therapy of HLA haploidentical related T-cell undepleted Allo-BMT and Chinese medicine plus immunosuppressants with pre-harvest G-CSF application in doner could effectively reduce the incidence of acute severe GVHD and raise the disease-free survival rate in treating leukaemia.
