BACKGROUND:Subcutaneous effusion often occurs after digital shaping titanium mesh cranioplasty, and affects therapeutic effects.
OBJECTIVE:To explore the causes and corresponding prevention measures of subcutaneous effusion after digital shaping titanium mesh cranioplasty.
METHODS: We retrospectively analyzed the clinical data and treatment methods of 19 cases of subcutaneous effusion after digital shaping titanium mesh cranioplasty, summarized the postoperative complications and explored the effective methods for prevention and treatment of subcutaneous effusion.
RESULTS AND CONCLUSION: After active treatment, five cases of dural breakage, four cases of foreign body stimulation, three cases of getting out of bed early, three cases of early extubation, three cases of long-time operation repair, and one case of excessive use of electric knife were al cured. Dural breakage and foreign body stimulation is considered as the main causes of postoperative effusion. Patients with subcutaneous effusion were given releasing elastic bandage, aspiration, and strict bed rest. After these active treatments, patients were al cured. Subcutaneous effusion may result from single or mixed factors. The above-mentioned causes are only a part. Non-central suspension, incomplete hemostasis, and preoperative excessive colapse of the bone window are al reported to be the reasons for the occurrence of subcutaneous effusion.

Objective To explore the effect of comprehensive intervention on anxiety in patients of acute myocardial infarction (AMI) undergoing intra-aortic balloon pump (IABP). Methods 50 patients with AMI undergoing IABP with the score of Hamilton Anxiety Rating Scale (HAMA) more than 14 points, were divided into conventional intervention group (n=25) and comprehensive intervention group (n=25). The conventional intervention group received all the conventional nursing measures including cognitive behavioral intervention, and the comprehensive intervention group received propofol intravenous pumping in addition with Ramsay sedation at II-III level. The vital signs, HAMA scores, major cardiovascular events, and vascular complications were recorded before and the 1st-5th days after intervention. Results The HAMA scores, systolic blood pressure, diastolic blood pressure and mean pressure decreased in most of the time points after intervention in the comprehensive intervention group (P<0.05). And there was no complication such as low blood pressure, respiratory depression. The incidence rates of cardiac arrhythmias, puncture hematoma/bleeding and catheter displacement were lower in the comprehensive intervention group than in the conventional intervention group (P<0.05). Conclusion Comprehensive intervention can improve the symptoms of anxiety in the patients with AMI undergoing IABP, and reduce the incidence of arrhythmia, vascular complications and catheter displacement.

Objective To investigate the expression of miRNA-301a-3p in pancreatic cancer and to correlate the expression on invasion , migration and colony formation of pancreatic cancer cells .Methods The expression of miRNA-301a-3p in 20 paired pancreatic cancer tissues and matched adjacent tissues , and pancreatic cancer cell lines and normal pancreatic ductal cells were detected by real -time PCR.miRNA-301a-3p mimics or inhibitors were used to up-regulate or down-regulate the miRNA-301a-3p level in pancre-atic cancer cell lines in order to figure out the effects of miRNA-301a-3p on cell invasion, migration and col-ony formation of pancreatic cancer cells , respectively .Results In pancreatic cancer tissues and cell lines , miRNA-301a-3p was significantly up-regulated when compared with the matched adjacent tissues ( P <0.05) and normal pancreatic ductal cells (P<0.05), respectively.Overexpression or downexpression of miRNA-301a-3p enhanced or suppressed colony formation , invasion and migration abilities of pancreatic cancer cells in vitro.Upregulation of miRNA-301a-3p promoted tumorigenesis in vivo.Conclusion miR-NA-301a-3p might function as an oncogene to promote tumorigenesis in pancreatic cancer .

Objective To investigate the effect of KIR-HLA receptor-ligand model on the unrelated allo-hematopoietic stem cell transplantation (Allo-HSCT) of acute lymphoblastic leukemia (ALL). Methods The KIR genotype of 23 pairs of ALL patients and their HLA-matched unrelated donors obtained from the Database of China Marrow Donor Program. KIR genotype was determined using PCR-SSP. The expression of inhibitory KIR(iKIR) was determined by flow cytometry analysis on recipients after HSCT. Results Among all 23 donor/recipient pairs, 17 donors with KIR2DL2/L3 could find corresponding HLA-Cw1, 3, 7, 8, 12, 14 ligands in their recipients. Six donors with KIR2DL1 could match with HLA-Cw6, 15 in recipients. Sixteen donors with KIR3DL1 could recognize HLA-Bw4 and 12 donors with 3DL2 could find HLA-AI1 in their corresponding recipients, respectively. Ninteen patients were successfully transplanted, and the death rate of transplantation were 33.3% (2/6)and 40.0% (2/5) in KIR receptor-ligand matched model and the graft versus leukemia(HVG) KIR ligand-mismatching pattern. The frequency of acute graft versus host disease(GVHD) was 50.0% and death rate was 12.5% (1/8) in GVH KIR ligand-mismatching. The incidence rate of activated GVHD(aGVHD) was 20.0% in the HVG KIR ligand-mismatching. Five donor/recipient pairs of KIR gene typing were the KIR-haplotype A, 2 donor/recipient pairs with KIR2DS4 * 001/002 were died, 3 donor/recipient pairs with KIR2DS4 * 003-007 were obtained the disease free survival. The expression of CD158a/2DL1 was low when the patient had no aGVHD, but became much higher when aGVHD occurred. The percentage of NK cell of the patients was decreasing since transplantation, but still higher than normal after HSCT[ (23.4 ± 3.8 ) % vs (2.04 ± 0.58) %, P < 0.05 ]. Conclusion Analysis on KIR-HLA gene loci pattern may provide a useful parameter in predicting the clinical outcome of HLA-matched unrelated allogeneic hematopoietic stem cell transplantation for leukemia patients. Moreover, it may help to increase overall survival and disease free survival after HSCT by preventing the development of GVHD.

Objective To assess the effect of low-dose cytarabine and aclarubicin in combination with gran-ulocyte colony-stimulating factor (G-CSF) protocol (CAG) in patients with acute myeloid leukemia (AML),and to understand the potential factors affecting the outcome of CAG induction therapy, therefore to find the optimum pa-tients for CAG therapy. Methods Twenty-one AML patients were enrolled in the current study. All patients were treated with CAG regimen including cytarabine (10 mg/m~2, subcutaneously, every 12 h, days 1 - 14), lacinomycin (5～7 mg/m~2,intravenously,every day, days 1 -8) ,and G-CSF (200 μg/m~2,subcutaneously, every day,12 h be-fore Ara-C was given) priming. Results The overall complete remission (CR) rate of the 21 AML patients was 66.7% (14/21). The CR rates was 87.5% (7/8) in patients older than 60 yrs,60.0% (9/15) in the refractory or relapsed patients,83.3% (5/6) in the MDS transformed AML patients. The CR rates for patients with hyperprolif-erative BM and median to poor proliferative BM were 33.3% and 91.7% ,respectively(P =0.009). The median o-verall survival (OS) time of the 21 AML patients was 450 days. Two-year survival rate estimated by Kaplan-Meier Method was 30.6%. The overall median disease free survival (DFS) was 165 days. The median OS time for those refractory or relapsed was 435 days. The median OS time for those with poor cytogenetic state or standard or good cytogenetic state was 140 days and 620 days, respectively (P = 0.001). The median OS time for patients with hyperproliferative BM and median to poor proliferative BM was 321 days and 620 days, respectively (P = 0.05). The median recovery time of granulocytes above 1.0×10~9/L was 8 days. The median duration of fever was 3.5 days. The rate of infections exceeding WHO grade Ⅱ was 42.9%. No early death occurred. Conclusions The CAG induction therapy may have a higher CR rate in patients with refractory or relapsed AML, elderly AML and secondary AML from MDS transformation, and extend the median overall survival time in refractory or relapsed patients. CAG therapy can not improve the outcome of patients whose BM was in high grade proliferation state or whose cytogenetic state was poor. CAG therapy can shorten the duration of agranulocytosis and decrease the inci-dence of serious infection. Therefore, CAG therapy is worth recommending to patients who can not endure the rou-tine intensive chemotherapy.

Objective To investigate the characteristics of ocular movement disorders in patients with multiple sclerosis (MS) and neuromyelitis optica (NMO), and explore the clinical application of videonystagmograph (VNG) exami?nation in the diagnosis and differential diagnosis of MS. Methods Sixteen MS ,10 NMO and 30 control ( sudden deafness ) patients were enrolled prospectively. Ocular movement disorders including saccades, gaze fixation, smooth pursuits, opto?kinetic nystagmus and spontaneous nystagmus were evaluated by using VNG. Results The positive rate of ocular motility disorders in MS patients detected by VGN was 68.75%. The incidences of abnormalities in saccades, smooth pursuits and optokinetic nystagmus were significantly higher in MS than in control groups (P= 0.000, 0.001 and 0.001, respectively). The positive rate of ocular motility disorders in NMO patients detected by VGN was 80.00%. The incidences of abnormal?ities in saccades, gaze fixation, smooth pursuits and optokinetic nystagmus were significantly higher in NMO than control groups (P=0.000, 0.012, 0.000 and 0.002, respectively). The positive rate of ocular motility disorders was not significant? ly different in MS and MS patients (68.5%vs. 80%,P>0.05). Compared with bedside physical examination, VNG showed a notable higher sensitivity in the detection of ocular motility disorders(68.75% vs. 37.50%). Furthermore, VNG disor?ders might indicate brain lesions undetected by MRI. Conclusion This small sample research indicates that VNG is a valuable tool in the detection of ocular motility disorders as well as brain lesions in MS and NMO patients. However, its role in the differential diagnosis between MS and NMO is not confirmed.

OBJECTIVETo investigate the influence of tissue inhibitor of metalloproteinase 2 (TIMP-2) on the infiltrative patterns of human monocytic leukemic cell line SHI-1 in nude mice.

METHODS1) 1 x 10(7) TIMP-2 gene transduced SHI-1 (SHI-1-TIMP-2) and SHI-1 transduced MSCV gene (SHI-1-MSCV) cells were inoculated via tail vein into 6-week nude mice, which pretreated by splenectomy, cytoxan intraperitoneal injection, and sublethal irradiation(referred as SCI nude mice). 30 days after inoculation, half of the mice were sacrificed, and the infiltration patterns were investigated by histological exam and human CD45 immunohistochemistry, other mice were observed for survival time. 2) Leukemic cells inoculated subcutaneously into the axillary area of mice without any pre-treatment. On day 23 and 30, mice were sacrificed to measure the volume of neoplasm. TIMP-2 protein expression and the micro vein density were detected by immunohistochemistry.

RESULTSIn SCI nude mice inoculated via caudal vein with SHI-1-TIMP-2 cells, the survival time was shorter and infiltration (including in central nervous system) was higher than that in those inoculated with SHI-1-MSCV cells. However, in inoculated subcutaneously group, the neoplasm though grew rapidly at first, over expression of TIMP-2 limited the tumor growth and angiogenesis.

CONCLUSIONThe functions of TIMP-2 are diversity; the role of TIMP-2 in tumor infiltration and metastasis was worthy of further investigation.

BACKGROUNDInteractions of tumor cells with the microenvironment were deemed to promote the tumor invasion and metastasis. CXC chemokine receptor 4 (CXCR4) and extracellular matrix metalloproteinase inducer (EMMPRIN) had reported to participate in this process. However the roles of bone marrow microenvironment in leukemic infiltration were not well investigated.

METHODSA co-culture system between SHI-1 cells and bone marrow stromal cells (BMSCs) is used to simulate the interactions of leukemic cells with their microenvironment. The trans-matrigel invasion was used to detect the capability of SHI-1 cells invasion. The BMSCs and SHI-1 cells were mixed in a ratio of 1:10 and added to the millicell chamber coated with matrigel. Either the co-culture supernatant or the functional blocking peptide of CXCR4 and EMMPRIN were added to the trans-matrigel invasion system. The expressions of EMMPRIN in SHI-1 cells and BMSCs were detected by RT-PCR. The changes of the expression of matrix metalloproteinase-2, 9 (MMP-2, MMP-9), tissue inhibitor of metalloproteinase 2 (TIMP-2), and CXCR4 mRNA in SHI-1 cells were determined by real-time PCR. The concentration of stromal cell derived factor 1 (SDF-1) in serum free supernatant was measured by ELISA.

RESULTSBoth SHI-1 cells and BMSCs express EMMPRIN. SHI-1 cells could hardly invade the matrigel membrane; the coculture supernatant did not induce the invasion of SHI-1 cells. When contacting directly with BMSCs, SHI-1 cells invaded to the lower chamber of millicell were significantly increased. The functional blocking peptide of CXCR4 and EMMPRIN could significantly inhibit the invasion triggered by BMSCs. When co-culturing with BMSCs, the expression of CXCR4, MMP-2, MMP-9 and TIMP-2 mRNA in SHI-1 cells were significantly elevated in company with a significantly higher level of SDF-1 in the co-cultured serum-free supernatant.

CONCLUSIONThe interactions of leukemic cells and BMSCs play important roles in leukemic cell infiltration.

OBJECTRIVETo compare the differences in risk factors for low birth weight (LBW) between Han and Uygur full-term infants and to provide a basis for the prevention of LBW in newborn infants.

METHODSEighty-seven full-term LBW infants (38 Hans and 49 Uygurs) between March 2013 and June 2014 were selected as the case group, and 186 full-term normal birth weight infants (92 Hans and 94 Uygurs) were selected as the control group. A questionnaire survey was performed to investigate the related factors for LBW. Multivariate logistic regression analysis was carried out to determine the risk factors for LBW.

RESULTSThe birth weights in Uyghur LBW infants were lower than in Han ones (P<0.05). Multivariate logistic regression analysis showed that drinking (OR=2.472, P=0.015) and smoking (OR=2.323, P=0.007) by the father, pregnancy complications (OR=14.377, P<0.001), and times of pregnancy (OR=2.995, P=0.001) were the risk factors for LBW in Han infants, while drinking by the father (OR=1.968, P=0.007), times of pregnancy (OR=1.953, P=0.005), pregnancy complications (OR=10.283, P=0.002), and poor indoor environment (OR=1.367, P=0.027) were the risk factors for LBW in Uyghur infants.

CONCLUSIONSThere are differences in physical growth between Han and Uygur LBW infants. Han and Uygur infants share the same traditional risk factors for LBW, such as father's harmful behaviors like drinking, times of pregnancy, and pregnancy complications, however, the indoor environment also plays a role in the occurrence of LBW in Uygur infants.

Objective To explore the role of fibroblast growth factor receptor ( FGFR ) 1 in endothelial homeostasis via an induction of microRNA let-7s, with effects on AcSDKP(N-acetyl-seryl-aspartyl-lysyl-proline) and associated mitochondrial biogenesis. Methods Blocking FGFR1 signaling pathway, Western blot and immunofluorescence staining were used to measure mitochondrial fusion ( mitofusin-2, MFN2;optic atrophy protein 1, OPA1 ) and fission ( dynamin-related protein-1, DRP1 ) proteins and mitochondrial biogenesis by MitoTraker Green. Also real-time quantitative PCR(qPCR) was performed to test microRNA let-7' expression. Results FGFR1 signaling pathway was critical for AcSDKP maintaining mitochondrial biogenesis through induction of microRNA let-7b. In endothelial cells, the AcSDKP restored the triple[TGF-β2, interleukin (IL)-1β, tumor necrosis factor (TNF)-α]-suppressed microRNA let-7b-5p expression and associated with mitochondrial biogenesis. Such effect of AcSDKP was lost in either fibroblast growth factor receptor substrate 2 (FRS2) siRNA or neutralizing FGFR1 treated-cells. Similarly, AcSDKP lost its effect on mitochondrial biogenesis in microRNA let-7b-5p inhibitor-treated-cells. In addition, microRNA let-7b-5p mimic reversed the FRS2 siRNA-suppressed mitochondrial biogenesis in endothelial cells. Conclusion These findings demonstrated that FGFR1 is critical for maintaining mitochondrial biogenesis through control of microRNA let-7b-5p in endothelial cells.
