AIM:To study the effect of hsa-miR-218 on cervical cancer HeLa cell growth and the underlying molecular mechanism .METHODS:The lentivirus expression vector pmiR-218 targeting to hsa-miR-218 was constructed . pmiR-218 was transfected into HeLa cells .The number of viable HeLa cells was counted by the method of Trypan blue ex-clusion.The inhibitory rate of cell activity was detected by WST-8 assay.The expression of LIM and SH3 protein 1 (LASP1) at mRNA and protein levels was determined by real-time PCR and Western blot.The interaction between miR-218 and LASP1 was examined using a luciferase reporter assay .RESULTS:The lentivirus expression vector pmiR-218 tar-geting to hsa-miR-218 was constructed successfully and confirmed by DNA sequencing .Over-expression of miR-218 inhibi-ted the activity of HeLa cells with the inhibitory rates of 15%, 26%and 65%at 24 h, 48 h and 72 h, respectively .The difference between transfection group and blank control /negative control group was statistically significant .The luciferase activity was reduced when co-transfection with miR-218 mimics and LASP1-3’ UTR plasmid.The relative expression of miR-218 was increased after transfection with pmiR-218.Over-expression of miR-218 down-regulated the LASP1 expression at mRNA and protein levels by 25%and 75%respectively.Compared with blank control group and negative control group , the difference was statistically significant (P<0.05).CONCLUSION:pmiR-218 effectively inhibits the growth of HeLa cells in a time-dependent manner.miR-218 targets to the 3’UTR of LASP1, thus down-regulating the expression of LASP1 in HeLa cells .

Objective To evaluate the clinical value of microvascular anastomotic devices in the reconstruction of lower extremity defects by free flap transfer.Methods A retrospective review of 42 consecutive patients who underwent lower extremity microvascular reconstruction performed from May 2013 to November 2013 by microvascular anastomotic devices was performed.Patient charts were reviewed for age,sex,etiology of defect,location of defect,flap type,anastomotic technique,complications and flap survival.Results No patients had an arterial or venous anastomosis revised.The vascular anastomosis patency rates was 100％ and the flap survival rate was 97.6％.Total complication rate (9.5％) was due to 1 partial flap loss,1 partial skin graft loss and 2 hematoma.There were no intraoperative or perioperative complications involving the use of a microvascular anastomotic device itself.Conclusion Microvascular anastomotic devices have effective vessel anastomoses in lower extremity microvascular reconstruction.Thus,it presents an ideal tool for lower extremity microsurgical reconstruction.

Objective: To compare the efficacy of induction chemotherapy (IC) plus intensity-modulated radiotherapy (IMRT) with that of concurrent chemo-radiotherapy (CCRT) plus adjuvant chemotherapy (AC) for patients with loco-regionally advanced naso-pharyngeal carcinoma (NPC). Methods:Data of 240 patients with loco-regionally advanced NPC were reviewed. These patients were admitted to the Sun Yat-sen University Cancer Center between January 2004 and December 2008. Among the 240 patients, 117 under-went the IC+IMRT and 123 were treated with the CCRT+AC. The IC+IMRT group received a regimen including cisplatin and 5-fluoro-uracil (5-FU). The CCRT+AC group received cisplatin concurrently with radiotherapy and subsequently received adjuvant cisplatin and 5-FU. The survival rates of the patients were assessed by Kaplan-Meier analysis, and the survival curves were compared by Log-rank test. Multivariate analysis was conducted using Cox proportional hazard regression model. Results:The 5-year overall survival (OS), disease-free survival, distant metastasis-free survival, local relapse-free survival, and the nodal relapse-free survival were 78.0%versus 78.7%, 68.9%versus 67.5%, 79.0%versus 77.0%, 91.6%versus 91.0%, and 95.3%versus 93.7%in the IC+IMRT and CCRT+AC groups, respectively. The survival between the two groups exhibited no significant differences. Higher rates of Grades 3 to 4 nau-sea-vomiting (8.1%vs. 1.7%, P=0.023) and leukopenia (9.7%vs. 0.9%, P=0.006) were observed in the CCRT+AC group. Multivariate analysis revealed that N stage and age were significant prognostic factors for the OS of the patients with loco-regionally advanced NPC. Conclusion:The treatment outcomes of IC+IMRT and CCRT+AC were similar. Distant metastasis remained as the predominant mode of treatment failure.

Objective To evaluate the predictive value of modified early warning score (MEWS) and SMART-COP score on mechanical ventilation in patients with severe influenza A H1N1. Methods Fifty cases diagnosed with severe influenza A H1N1 were retrospectively analyzed. The MEWS and SMART-COP score were calculated. The area under the receiver operating characteristic (ROC) curve (AUC) was evaluated using ROC curve. MEWS, SMART-COP score and AUC were analyzed by Z test. Results The AUCs of MEWS and SMART-COP score for predicting mechanical ventilation were 0. 923 and 0. 889, respectively, which were not significantly different (Z=0. 548, P =0. 584).Conclusion Both of MEWS and SMART-COP score are predictive factors of mechanical ventilation in the patients with severe influenza A H1N1.

The treatment status and progress in T cell lymphoma including epigenetic involved mutations that control DNA and histone methylation were reported and intensively discussed in 2014 international T cell lymphoma forum.According to the theory,treatment with HDAC inhibitor belinostat and romidepsin for peripheral T cell lymphoma (PTCL) can achieve 29 ％-38 ％ overall response rate (ORR) and 13.6 months median relief time.NK/T cell lymphoma in southeast asia is a common malignant lymphoma,15 ％-28 ％ of the NHL accounted in China and Japan for,which is significantly higher than that in the European and American countries,mainly related to EB virus widespread infection.L-asparaginase enzymes,such as SMILE and AspMetDex,can make the early cases with more than 70 ％ long-term survival rate,advanced cases with 40 ％ response rate.Some new drugs,such as pralatrexate,combined with romidepsin can be used in PTCL cases to improve the complete remission rate.

OBJECTIVETo examine the therapeutic effect of combined use of obidoxime and atropine with artificial ventilation on respiratory muscle paralysis caused by omethoate poisoning in rats.

METHODSRats were exposed to 2 times the dose of LD50 omethoate and treated with atropine (10 mg/kg) to counteract cholinergic symptoms. When the rats' respiratory frequency became slower and breathed with difficulty, the trachea intubation and artificial ventilation was carried out. The rats in group A were continuously treated with atropine. The dose of obidoxime for Group B, C and D were 8, 15, 20 mg/kg respectively, given at the same time as artificial ventilation and 1, 2, 3 hours later. The doses of atropine was reduced to 1/3 - 2/3 of the first dose so as to maintain the rats atropinized. If the rat survival was beyond 60 minutes after withdrawal of artificial ventilation, the combined treatment was considered successful. The function of isolated phrenic diaphragm of the rats was observed with MS-302 physiological and pharmacological analysis instrument.

RESULTSNone of the rats in Group A was successful after withdrawal from artificial ventilation and the function of phrenic diaphragm appeared poor; whereas > 80% of the rats in B, C, D Group were successful after withdrawal from artificial ventilation in 3 h and the function of phrenic diaphragm remained well. The survival rate in B, C and D groups were higher after withdrawal from artificial ventilation than that in Group A(P < 0.01). The function of phrenic diaphragm in Group B, C and D were gradually decreased after ACh was added into the container.

CONCLUSIONSCombined use of suitable dose of obidoxime and atropine with artificial ventilation for respiratory muscle paralysis caused by omethoate poisoning could promote the recovery of diaphragm function and reduce the death rate in poisoned rats.

OBJECTIVETo evaluate the cutaneous histological and ultrastructural changes of dogs following hair removal by Alexandrite laser.

METHODSSeven healthy dogs with dark hair were treated for hair removal with the Alexandrite laser and skin biopsies were taken after 0.5 h, 2, 3, 5, 10, and 30 days. Specimens were examined with light microscopy and transmission electron microscopy.

RESULTLaser-treated specimens showed widespread coagulation and charring subcutaneous hair shafts. These obviously damaged follicles were randomly dispersed among intact follicles within the same treatment sites. Microscopic changes were also seen in the basal epidermis where melanin was concentrated. A low level of inflammatory response was seen up to 10 days followed laser treatment. The efficiency in higher fluence test area was better than the lower one; the degree of damaged follicles with double pulse was similar to that with single pulse.

CONCLUSIONAlexandrite laser irradiation results in selective damage to follicles and microscopic changes in the basal epidermis. Alexandrite laser hair removal does not lead to scar formation; the efficiency of laser hair removal is fluence-depent; the degree of damaged follicles with double pulse is not different with single one; the cooled hand piece can minimize epidermal injury.
