1.Mammalian target of rapamycin inhibitors and tumor therapy
Journal of International Oncology 2012;39(8):576-579
Mammalian target of rapamycin(mTOR) inhibitors have the anti-tumor ettect,which have been known early.The traditional mTOR inhibitors include rapamycin and its derivatives,which have been applied in clinical use early.Nowadays,some new small molecule inhibitors such as the PI3K/mTOR duel inhibitor,Torinl,one after another are found to play a unique role in the tumor therapy.
2.ERG theory in analysis of work satisfaction of nurses in general hospitals
Chinese Journal of Hospital Administration 2009;25(10):702-706
Objective Investigation of satisfaction of clinical nurses and analysis of the influence factors.Methods The ERG theory of Clayton Alderfer is used as the framework to design the questionnaires,for questionnaire investigation of 249 nurses in the hospital in a stratified sampling,Results The score of general satisfaction of nurses for their work is 3.40±0.58;the satisfaction of nurses for the management of their leaders and teamwork is high,as the satisfaction scores are 4.01±0.76 and 3.60±0.71 respectively;their satisfaction for salary,welfare and social identity is low,as the scores are 2.46±0.86 and 2.50±1.02 respectively.Work satisfaction varies with departments,academic levels,monthly income,work shifts,age,seniority,and objectives for their choice of nursing as profession.Conclusion Managers are prompted to enhance their work in view of the satisfaction scores on survival,mutual relations and growth,as well as factors affecting satisfaction,and take various incentives to improve overall satisfaction of nurses.

[Objective] To gain more insight into the presentation,diagnosis of Bertolotti's syndrome and to investigate the indications,the procedure and the early clinical results of minimally invasive transverse process plasty.[Methods]Thirteen cases(Santavirta Type I)with Bertolotti's syndrome underwent minimally invasive transverse process plasty under MED X-tube(Medtronic Sofamor)from Apr.2006 to Dec.2008.The Visual Analogue Scale(VAS),Modified Oswestry Disability Index(ODI)score and subjective sensation of patients were recorded to evaluate the function.[Results]The operation blood loss was from 120 ml to 800 ml and operative time was from 60 to 280 minutes,average 115minutes.There was no severe complication.Nine cases were followed up for 10 to18 months,average 13.6 months.The VAS decreased from(6.7?2.2)before operation to(2.2?0.7)one week after operation and(2.8?0.9)three months after operation.ODI score decreased from(27.8?3.6)before operation to(5.9?2.2)three months after operation.The results were excellent in 10 case and good in 3 cases.[Conclusion]Minimally invasive transverse process plasty is an effective method for Bertolotti's syndrome,especially for Santavirta type I.It shows less blood loss and injury and deserves to be spreaded.Disectomy is recommended in one stage if the patient is complicated with disc herniation.

Recent studies have found that autophagy was not only involved both in the occurrence and development of viral myocarditis (VMC),but also,it plays a key role in anti-viral infections by degradating the viral components,presenting viral antigens and activating the immune response.Meanwhile,the virus can also escape the protective antiviral activity and maintain their own survival and replication by inducing the autophagy of the host cells,becoming the accelerator of the viral infection.The interaction of the virus and the host cell autophagy in VMC is a complex process.Its detailed pathogenesis has yet to be further explored.

Objective To compare the propagation speed and physical parameters between underwater blast wave and air blast wave. Methods The physical parameters of blast wave were measured by PCB pressure transducers (USA) during underwater and air explosions of 200g, 500g and 1000g TNT respectively. Consequently, the propagation speed, peak overpressure value, positive duration and impulse of blast wave were analyzed. Results Underwater blast wave was characterized by high propagation speed, high peak overpressure value, great impulse, however, short duration. Compared with air blast wave, the propagation speed of underwater blast wave was 3.70-4.30 times higher than that of air blast wave, the peak overpressure value was 227.15-247.86 times higher, and the impulse was 8.48-11.80 times greater than that of air blast wave. Conclusion Underwater blast wave propagates faster than that air blast wave. Meanwhile, it also peoduces higher peak overpressure value and impulse. This result is helpful for the evaluation of injury severity and treatment of underwater blast injury.

Objective In order to know the harm of indoor environment pollutants to the human health. Methods Formaldehyde, benzene, dimethylbenzene, ? radiation and radon were selected as the factors of indoor environment pollution assessment, considering about the inhale and exposure path of indoor air, assessment model which from the production of inland and overseas was used to evaluate the health risk during Mar.-Oct.2005. Results The average risk of the indoor air pollution in Jiangxi province was 1.93?10-4/a, radiation (? radiation, radon) was 1.32?10-4/a, accounted for 68%. Formaldehyde was 4.64?10-5/a, accounted for of 24%. Benzene was 1.41?10-5/a, accounted for 7%. Dimethylbenzene was 1.32?10-9/a, which could be ignored. Conclusion The health risk of indoor environmental air pollutants in each city of Jiangxi province is higher than the acceptable lever(10-5/a).

Objective To investgate the efficiency of autologous fat grafting for breast augmentation by improving low negative pressure mechanical liposuction.Methods A total of 37 cases of breast augmentation by autologous fat grafting were reviewed;group A included 19 cases of improved low pressure mechanical liposuction,and group B had 18 cases of traditional syringe liposuction.Respectively,the operating time of harvesting 800 ml fat granules (standing 30 mins) were recorded,and operative blood loss by testing the red blood cell count of lower mixed liquid was calculated,and then growth increment of nipple chest circumference of 6 months after operation were measured.The valid follow-up satisfaction scores were counted.Results The operating time of harvesting 800 ml fat granules were (53.32±4.73) mins for group A and (80.78±7.86) mins for group B,respectively;operative blood loss was (81.58±10.80) ml for group A and (72.94±13.45) ml for group B;All P<0.05.The valid follow-up satisfaction scores were 78.9% (15/19) for group A and 77.7% (14/19) for group B.Growth increment of nipple chest circumference of 6 months after operation between groups were no statistical significance (P>0.05);but the remarkable difference within both groups in internal comparison existed between 6 months and 1 month after operation (P<0.05),also between 3 months and 1 month after operation (P<0.05).Conclusions Improved low pressure mechanical liposuction in breast augmentation by autologous fat grafting is able to enhance the surgical efficiency evidently and shorten the operating time significantly.

objective: To study the effects of BMP on the growth of osteosarcoma cells. Methods: Human antisense BMP2 retrovirus expression vector was constructed and transfected into human osteosarcoma OS 9901 cells by Lipofect AMINE. Positive cell clones were selected with G 418. The expression of BMP and PCNA were determined by immunohistochemical methods, image analysis and expressed as grey level. The morphology and cell cycle distribution of the cells were studied by electronmicroscope and flowcytometry respectively. Results:The grey levels of BMP and PCNA in the transfected cells were 198.4?8.51 and 197.3?3.22, those of the control were 135.1?12.32 and 142.9?8.47,respectively. G 1, G 2 and S phase cells were 51.9%,18.2% and 22.7% in the cell cycle of transfected cells, while those of the control were 52.8%,11.1% and 36.1%, respectively.Increased lysosome and small pieces of chromatin were observed in the transfected cells under electronmicroscope. Conclusion:Transfection of antisense BMP2 may inhibite the expression of BMP and proliferating activity of osteosarcoma cells.
