Objective To probe into the way for relieving pains irrelevant to incision but associated with the event of pneumoperitoneum by means of physiotherapy, wherein the said pains occur after a gynecologic celioseope operation.Methods Random option of 207 patients after the gynecologic operation was conducted and the patients were divided into 3 groups at random that were on the man-care,instrument and ordinary basis.Each group consists of 69 cases.In man-care group,artificial massage at the points (hereafter called mann-care group)Was adopted.The instrument group adopted microwave devices to heal (hereafter called instrument group).And the ordinary group adopted regular care of post operation (hereafter called ordinary group).We observed and compared three methods,to see whether they may relieve the pains irrelevant to incision.Results The point massage and microwave therapy can relieve the complicated pains irrelevant to incision after a gynecologic operation,and the effect thereof is obviously better than that of the ordinary care.Conclusions As to the complications such as pains irrelevant to incision after gynecologic operation,the point massage,microwave and relevant physiotherapy can function well and are comparatively ideal.

To evaluate the inhibitory effects of long antisense RNA on HBV replication in HepG2.2.15 cells. The coding region of HBV S gene was cloned into pTARGET vector in sense and antisense orientations and the recombinant plasmids were transfected into HepG2.2.15 cells which were divided into HBS2 (antisense RNA) group, HBS4 (sense RNA) group and control group. HBsAg and HBeAg in the culture supernate were detected by ELISA. The HBV DNA in the supernate was quantified by real-time PCR. After treatment, the levels of HBsAg in HepG2.2.15 cell supernatants of three groups were 0.621+/-0.027, 3.399+/-0.018 and 2.232+/-0.187 respectively; the levels of HBeAg were 0.749+/-0.019, 1.548+/-0.025 and 1.570+/-0.044 respectively and the levels of HBV DNA were 1.597+/-0.082, 3.381+/-0.297 and 3.610+/-0.063 respectively. The expressions of HBsAg and HBeAg and the HBV DNA level in HBS2 group were remarkably reduced as compared to the control (Z = -2.309, P value is less than 0.05); whereas the sense plasmid transfection (HBS4) did not affect HBeAg (Z = -0.866) and HBV DNA (Z = -1.155) levels in the culture supernate but slightly increased the HBsAg level (Z = -2.309). Antisense RNA might be a useful tool to repress HBV replication.

OBJECTIVETo explore the method to repair large scalp and face scars.

METHODS1-3 expanders under the scalp were needed for repair the scalp scar. The expanded deltopectoral flaps were transferred to repair the face scar.

RESULTS12 cases were treated with satisfactory results. All the flaps survived and the donor sites were closed primarily. 2 cases had expander exposure which didn't affect the treatment results. Atrophic cutaneous striae was occurred because of overexpansion.

CONCLUSIONSSkin expansion is a good method for large scalp and face scar.

OBJECTIVETo investigate the expression of miR-550a-5p in bone marrow of patients with myelodysplastic syndrome (MDS), and to predict its target genes and function by bioinformatics analyses, so as to provide the evidence to furthre explore the role of miR-550a-5p and its target genes in pathogenesis of MDS.

METHODSReal-time PCR was used to detect the expression of miR-550a-5p in 54 MDS patients, 16 acute myeloid leukemia transformed from MDS (sfAML) and 19 healthy controls, and the correlation between the expression of miR-550a-5p and clinical pathologic characteristics of MDS, including chromosome, percentage of marrow blasts, absolute neutrophil count, platelet count and hemoglobin levels were analyzed. The sequence of miR-550 was searched in miRBase database. Target genes of miR-550a-5p were predicted by Microcosm,Miranda and Targetscan, and the predective results were collected, then the enrichment analyses of target gene function(GO) and signalling pathway(pathway of miR-550a-5p) were carried out by using gene ontology darabase and KEGG database.

RESULTSThe expression of miR-550a-5p in bone marrow of all MDS patients was higher than that in controls: the expression level of miR-550a-5p in low risk MDS and middl risk 1 MDS was 1.7 times of controls (P=1.23×10); the expression of miR-550a-5p in midde risk 2 MDS and high risk MDS was 1.9 times of controls (P=1.20×10); the expression of miR-550a-5p in tAML was 2.0 times of controls (P=5.61×10). The miR-550a-5p expression level was up-regulated gradually with the enhancement of disease risk of MDS, but there was no correlation between the expression level of miR-550a-5p and clinical pathologic characteristics of MDS(chromosome: Normal: 1.11±0.19, Abnormal:1.26±0.15, P>0.05; Percentage of Marrow Blasts: r=0.29,P=0.07; absolute neutrophil count: r=-0.02,P=0.89; hemoglobin level: r=0.09,P=0.57; platelet count: r=0.25,P=0.08). The sequence of miR-550 was conservative among different species, and the prediced results indicated that there were 19 target genes in intersection. The functions of target genes were enriched in regulation of stress-activated cascade, MAPK pathway, regulation of muscle organ development, regulation of protein homodimerization activity and other biological processes; they participated in some molecular functions including enzyme activity, combination processes of some molecules as protein, cAMP and domain existed in cell junction, synapse, coated vesicle, dendrite and other cellular components. Two of them-PDLIM2 and PSME1 were selected which might play a role in pathologic mechanism of MDS regulated by miR-550a-5p.

CONCLUSIONThe expression of miR-550a-5p in bone marrow of MDS patients increases specifically, and miR-550a-5p may play a role in the pathogenesis of MDS through regulation of target genes, PDLIM2 and PSME1.
