Conclusion The focus intervention on the functional recovery of patients with total hip replacement may have some help, reduce complications and improve patient satisfaction.

Objective To study the influence of survivin mutant-T34A ( survivinT34A) and survivin deletant-N-terminal 8 amino acids residues ( survivinN-8AA ) on the cell cycle distribution and chemosensitivity in human ovarian cancer HO-8910 cells for explorating the roles of modified survivin-mediated apoptosis induced by chemotherapeutic agents and possible signaling pathways involved. Methods pcDNA3.1 plasmid contained wild-type, survivinT34A and survivinN-8AA genes were transfected into HO-8910 cells,respectively, the control groups were HO-8910 cells transfected with pcDNA3. 1 plasmids. The expression of mRNA was examined by reverse transcription(RT) PCR and identified by DNA sequencing; the cell cycles were determined by flow cytometer analysis ( FCM ); the growth inhibitions rate of cisplatin ( DDP),paclitaxel (PTX) and LY294002 on the transfected cells were determined using methyl thiazolyl tetrazolium (MTT) assay. Results (1) The RT-PCR procedures and genome sequences showed that the survivin mRNA were expressed stable in the transfected HO-8910 cells. (2) There was lower percent of G0/G1 phase cells in SN-HO-8910 cells than that in PC-HO-8910 cells (44. 72% vs. 49.64%, P ＜0. 05) ;while higher percentage of G2/M phase and S phase cells( 1.06% and 54. 22% vs. 0. 56% and 49. 80%, P ＜ 0. 05 ).There was lower the G2/M phase and S phase cells in M-HO-8910 cells 0. 16% and 36. 33%, than that in PC-HO-8910 cells( P ＜ 0. 05 ); while higher percentage of G0/G1 phase cells(63. 51% ,P ＜ 0. 05 ). G0/G1 ,G2/M and S phase cells in Sur-HO-8910 cells were 54. 46%, 0. 62% and 44. 92%, and there were not significantly difference ( P ＞ 0. 05 ), compared to those in PC-HO-8910 cells. ( 3 ) The inhibitory concentration ( IC50 ) of DDP and PTX were higher in Sur-HO-8910 cells than those in control cells [(20. 4 ±6. 1)vs. (14.4 ±3.9)μmol/L,(36.7 ±4.0) vs. (28.6 ±3.6) μmol/L;all P＜0.05]. The IC50 of DDP and LY294002 in SN-HO-8910 cells were lower than those in control cells[(7. 6 ± 1.0) vs. ( 14. 4 ± 3.9)μmol/L, ( 13.2 ± 4. 0) vs. (41.0 ± 7. 9 ) μmol/L; all P ＜ 0. 01]. The IC50 of PTX [( 37. 9 ± 4. 8 ) μmol/L]in SN-HO-8910 cells were higher than that in control cells(P ＜0. 05). The IC50 of DDP in M-HO-8910 cells [(9.9 ± 1.2) μmol/L] were lower than that in control cells(P ＜0. 05) ,and the IC50 of LY294002 in M-HO-8910 cells [(66. 9 ± 4. 8) μ mol/L] higher than that in control cells ( P ＜ 0. 01 ). Conclusions The changes of cells cycle distribution caused by survivinT34A or survivinN-8AA enhanced the G2/M cell cycle-dependent chemosensitivity of PTX. Compared to survivinT34A, survivinN-8AA preferentially to mediate the cytotoxicity of DDP and LY294002, suggesting that it may be related to the cell cycle-dependence of survivin function and to blockage of the formation of its active dimer.

Objective To investigate the relationship and mechanism of the serum vitamin D levels with insulin sensitivity and adipokines APN,RBP4,visfatin and TNF-α in patients with gestational diabetes mellitus(GDM). Methods A total of 101 patients with gestational diabetes( GDM group) and 50 pregnant women with normal blood sugar( control group) were recruited to detect the serum levels of correlative biochemical indexes,APN,RBP4,visfatin,TNF-α and 25OHD3 using an HPLC method. Twenty-four patients in the GDM group diagnosed with vitamin D deficiency(<25 nmol·L-1 ) were randomized to receive either 1,25(OH) 2D3(0. 25 μg·d-1) orally or no treatment. Serum levels of correlative biochemical indexes were detected after 1 month. Results GDM patients had 25OHD3 levels significantly lower than the control group(P<0. 05),APN levels lower than the control group,and RBP4,visfatin,TNF-α levels significantly higher than the control group(all P<0. 05). After 1 month of 1,25(OH) 2D3 treatment,HOMA-IR increased,while HOMA-β decreased. APN levels was positively correlated(r= 0. 526) with 25OHD3;RBP4,visfatin,TNF-α decreased and were negatively correlated with 25OHD3( r values were -0. 272,-0. 153,-0. 072). Conclusion Vitamin D can reduce the adipokines RBP4,visfatin,TNF-α,increase APN,and thus play a protective role for gestational diabetes.

OBJECTIVESTo develop techniques which can be used to detect genetic material of measles virus from clinical samples to make diagnosis and differentiate atypical measles from other exanthematous infections early in clinical course.

METHODSA nested reverse transcriptase-polymerase chain reaction (RT-PCR) was developed to amplify gene fragment with the size of 301 bps from N gene of measles virus in throat swabs and urine samples collected from infants and children who were suspected measles cases. Before the test was used for clinical samples, preliminary tests were performed to determine the sensitivity and specificity of the test. The sensitivity of the test was determined by plaque assay using measles virus strain Edmonton and the specificity of the test was determined by cross-reaction with rubella virus, respiratory syncytial virus, influenza A and B viruses, enterovirus, adenovirus, human cytomegalovirus (hCMV), EB virus, and herpes simplex virus I. Serum specific IgM antibody against measles virus was also tested by ELISA.

RESULTSMeasles virus with the titer of 0.53 pfu could be detected by using the nested RT-PCR developed in this study. No amplification was found with the nested RT-PCR when rubella virus, respiratory syncytial virus, influenza A and B virus, enterovirus, adenovirus, hCMV, EB virus, and herpes simplex virus I were used as templates. Out of 116 throat swabs collected from suspected measles cases, 70 (60.3%) were measles RNA positive. For urine samples, 48 out of 74 (64.9%) were positive. Both throat swab and urine samples were collected simultaneously from 73 patients. Among those, 71 (97.3%) showed consistent results. Serum specimens were collected from 110 suspected patients. Among those, 65 (59.1%) and 61 (55.5%) were measles virus specific IgM antibody positive detected with ELISA kits from two different sources, respectively. Out of 110 sera samples, 106 (96.4%) showed consistent results. The consistency of the gene amplification and specific IgM antibody detection was 80.8% as shown by 84 out of 104 patients from whom throat swab and sera were collected at the same time.

CONCLUSIONThe data indicate that the nested RT-PCR developed in this study is sensitive and specific for detection of gene fragment of measles virus from clinical samples. The test is superior to the commonly used specific IgM antibody detection because of identifying gene material in early clinical stage, and even single clinical sample can be tested.

Objective To report two cases of severe pulmonary complication after bortezomib treatment for multiple myeloma. Methods Two cases of severe pulmonary complication after bortezomib treatment patients with relapsed multiple myeloma wereas discussed with review of literature. Results Two relapsed MM patients were treated with bortezomib and thalidomide or dexametbasone. Cough, dyspnea, fever and hypoxia developed after completion of bortezomib. Chest X-ray revealed bilateral pulmonary infiltrates,but infection was not identified with sputum cultures, and broad-spectrum antibiotics were ineffective.Conclusion Severe pulmonary injury was rare complication in patients receiving treatment for multiple myeloma, however, it was a life-threatening disorder. Prophylaxis corticosteroids maybe effective. Although corticosteroids are effective, but the mechanism of lung injury associated with bortezomib is unclear, and further evaluation of this potential toxicity is appropriate.
