Objective:To study the effects of the overexpression of hsa-miR-202 on the proliferation and molecular mechanism of lung cancer A549 cells. Methods:A sequence of hsa-miR-202 with ppG/miR/eGFP/Blasitidin pasmid was directionally connected and a eukaryotic expression vector pmiR-202 of the target hsa-miR-202 gene was constructed. pmiR-202 was transtected to A549 cell with Lipofectamine 2000. The WST assay was used to detect the cell proliferation rate, and RT-PCR was used to detect the relative gene expression levels. Western blot analysis was used to detect the IL-10 protein expression levels. The interaction between miR-202 and IL-10 was examined using a luciferase reporter assay. Results:The design from the DNA sequencing results shows that a eukaryot-ic expression vector of miR-202 was successfully constructed. The proliferation inhibition rates of A549 cells by Pmir-202 were 12%, 38%, and 52%. The differences in the treatment group compared with the blank control and negative control groups were statistically significant. The RT-PCR results showed that the relative expression levels of miR-202 increased after transfection with pmiR-202. Over-expression of miR-202 can downregulate the relative gene and protein expression levels of IL-10, and the relative levels were 25%and 0.75, respectively. Compared with the blank control and the negative control groups, the difference was statistically significant (P<0.05). The fluorescent activity was reduced when transfection was performed with miR-202 mimics, and IL-10-3'UTR plasmid was cloned. Conclusion: pmiR-202 effectively inhibited the proliferation of A549 cells and exhibited a time-effect relationship with miR-202 by targeted combination with IL-10 3'UTR to downregulate IL-10 expression in A549 cells.

Objective To report our experience on closure of patent arterial duct using Hem-o-lok polymer ligating clip under a direct vision.Methods From May 2001 to May 2007,84 patients with cast patent arterial duct were treated with Hem-o-lok polymer ligating clips.Under a direct vision,the clips were placed to close the patent arterial duct through a small left subaxillary incision.Results The mean operation time was 42 minutes(ranged from 30 to 60).No intraoperative bleeding occurred in this series.After the operation,heart murmur disappeared in all the patients and none of them died.They were followed up for 2 to 50 months(mean 28 months),during which no residual shunting or recanalization occurred.Conclusion It is microinvasive and safe to close patent arterial duct by using Hem-o-lok polymer ligating clip.

Objective To study the method, advantage and shortcoming of mini-laparoscopic treatment for indirect inguinal hemia in children. Methods 136 cases with indirect inguinal hernia(right:75cases,left:44 cases,bilateral:17 cases) had been treated by high ligation with mini-laparoscopy. Results The mean operation time was 10 mmin for unilateral hernia and 23 mmin for bilateral hernia. Among 119 cases with unilateral hernia,38 cases had been found with contralateral latent hernia. The mean of postoperative inhospital stay were about 1 ～ 2 day(s). All patients had been followed-up for 3 ～ 12 months,there were only 2 cases recurrence found but no complications was detected.Conclusion Mini-laparoscopic high ligation for indirect inguinal hernia in children is a single, safe, satisfactory, effective,and minimally invasive surgical method.

A study of PDCA Cycle in managing hospital medical complaints may introduce such a cycle into the medical complaints control system of a hospital, effectively handling the medical complaints process. Since 2006 when the cycle was introduced into the hospital for medical complaints control, such complaints have been cut back significantly by the end of 2009. Furthermore, such complaints are under control from the start, and prevented from growing into medical disputes, effectively improving quality of care. Such a cycle can effectively avoid medical complaints, enhance medical safety, and build a harmonious doctor-patient relationship.

This article sumarized a practise-based study of the hospital regarding the management of its medical activities.By means of priotizing medical safety in pre-job and on-the-job eduation,and regular trainings in this regard,a systemized medical safety education ssytem is put in place among medical staff of different types and levels.This achieved the purpose of higher awaress of medical safety in medical practice,and downsized medical complaints significantly.

Quality of care is key to medical safety which has a close bearing on patients’life and health,and on the branding and efficiency of the hospital.Medical safety is one of the key indicators of the overall performance appraisal of the hospital.This novel type of nurse-physician collaboration,abandoning the traditional model of health care,is a new integrated model of health care which improves the overall quality of care,enhances medical safety and patient satisfaction.This paper described in detail the implementation methods and steps of the collaboration,the progress of such a collaboration and its contribution to medical safety are also discussed.

OBJECTIVE:To investigate the clinical efficacy and safety of recombinant human epidermal growth factor(rhEGF) combined with lipoic acid in the treatment of diabetic foot. METHODS:A total of 68 patients with diabetic foot were randomly divid-ed into observation group and control group with 34 cases in each group. Both groups were given conventional therapy and Lipolic acid injection 0.6 ml added into Sodium chloride injection 250 ml. ivgtt(protecting form light),qd;observation group was additionally giv-en rhEGF for external use 1 ml and vaseline on the wounds,gauze dressing,qd. Treatment course of 2 groups lasted for 7 d. Clinical efficacy,ulcer area,the expression of Bcl-2 and Bax were compared between 2 groups as well as the occurrence of ADR. RESULTS:The total effective rate of observation group(94.1%)was significantly higher than that of control group(67.6%),with statistical sig-nificance (P<0.05). Before treatment,there was no statistical significance in ulcer area,the levels of Bcl-2 and Bax between 2 groups(P>0.05). After treatment,ulcer area decreased significantly, the level of Bcl-2 increased significantly in 2 groups,while the level of Bax decreased significantly;the improvement of observation group was more significant than that of control group,with statis-tical significance(P<0.05). There was no statistical significance in the incidence of ADR between 2 groups(P>0.05). CONCLU-SIONS:rhEGF combined with lipoic acid is effective for diabetic foot with good safety.

ObjectiveTo study the effect of bone mesenchymal stem cells (BMSC) transplantation into traumatic brain injury(TBI) rats by the external carotid artery on neurological function and learning and memory.MethodsTen adult SD rats were randomly divided into TBI group ( n =5 ) and BMSC transplantation group ( n=5).Feeney free falling method was used to establish TBI models.The experimental rats were administrated with BMSC via external carotid artery (ECA),while TBI rats were injected with sterile liquid medium of equal volume via right ECA.Neurological function were evaluated according to the modified neurological severity score (NSS) at 1,3,7,15 days.Morris water maze test was used to observe the animal capabilities of place navigation and space exploration at 15 days,then animals were sacrificed.Survival and migration of implanted BMSC in brains under fluorescence microscope. ResultAfter traumatic brain,varying degrees convulsions,paralysis,loss of balance function in rats were found.Compared with TBI group,BMSC transplantation decreased significantly NSS (P ＜0.01 ).BMSC transplantation significantly decreased on escape latency ( ( 20.48 ± 2.29 ) s ) than the TBI group ( ( 85.93 ± 47.48 ) s) (P ＜ 0.01 ).Moreover,BMSC group in the target quadrant dwell time ( ( 28.62 ± 1.72) ％ )and distance ( (29.05 ± 3.08 )％ ) as well as the number of passing the platform (8.00 ± 2.45 ) were significantly higher than the TBI group ( ( 19.37 ± 2.81 ) ％,(21.78 ± 3.06) ％,(2.00 ± 1.87) respectively,P ＜ 0.01 ).Transplanted BMSC could survive and migrate around injury brain through Hochest mark immunofluorescence.ConclusionBMSC can survive and migrate around injury brain by transplantation of external carotid artery,which results in a significant neurological function improvement and learning and memory increase in rats with traumatic brain injury.
