Public cardiopulmonary resuscitation(CPR)is an important strategy and method to deal with sudden cardiac death outside hospital by relying on the wisdom and strength of the whole society in China. The article summarizes the definition of public CPR, the subject of implementation, the core of construction and the implementation steps. With the support and guidance of the government, the public should join together,with the construction of the first responder, automatic external defibrillator and comprehensive prevention and control system as the core, and promote the implementation of training,practice and scientific research to achieve the ultimate goal.

BJECTIVE: To explore the effect of different convergent conditions on accuracy of simulation results from a three dimensional finite element model of the pelvic ring.METHODS: A first-order linear load of 600 was applied on the S_1 vertebral endplate in an established three-dimensional finite element model. The step length was set to 0.1 s. The boundary condition was set as constraint of 6 degrees of freedom in the proximal femur. Static and dynamic explicit convergences with 6 different weight scale factors were calculated retrospectively,and all the simulated results were compared with the experimental results in order to verify the accuracy. RESULTS: The static convergence predicted most accurate with the linear regression coefficient 0.88. With the increase of weight scale factor, the time cost decreased. However, the accuracy of the predicted results decreased. There was statistically difference between the simulation results and experimental results when the weight scale factor achieved 3 000 (P<0.05) and the coefficient of linear regression was lower than 0.8.CONCLUSION: It suggested that as for the complex finite element model, especially when the model contains complex contact conditions, dynamic explicit convergence can be an alternative solution to static convergence if the latter failed. Also proper weight scale factor should be used to decrease the time cost under the condition that the error was in the limited.

Objcetive: To investigate the effect of resveratrol (RES)combined with cisplatin (DDP)on the cholangiocarcinoma cell line FRH-0201 in vitro. Methods: FRH-0201 cells were exposed to different concentrations of RES or (and)DDP. Cell morphological changes were observed by light and fluorescence microscopy. Inhibition of cell proliferation was measured by MTT and colony-forming assay. And the flow cytometry were performed to detect the cell apoptosis rate and cell cycle. Results: Resveratrol inhibited the proliferation of FRH-0201 cells in a time-and dose-dependent manner in the concentration of 5～320 ?mol/L and the IC50 values after the exposure of 24, 48, and 72 h were 55.35, 32.84, and 28.01 ?mol/L respectively. RES and DDP had synergetic effect in the inhibition of FRH-0201 cells. Conclusion: RES can inhibit the growth of FRH-0201 cells and has the synergetic effect with DDP.

28 days after injury (P < 0.05). In the fracture+spinal cord injury group, the level of serum transforming growth factor beta 1 had a rapid increase on the 7th day, and reached the peak on the 14th day, and then, this level had no significant decrease until the 28th day. In the simple fracture group, the level of serum transforming growth factor beta 1 began to increase on the 2nd day, reached the peak on the 7th day, and then decreased gradualy. Remarkable changes of serum transforming growth factor beta 1 levels in patients with bone fracture combined with spinal cord injury may be associated with fracture healing in different periods.

The rapid development of the globalization process has brought global health problems and made global health a hotspot in the world. China’s “One Belt and One Road” initiative has strengthened economic and trade exchanges between China and Asia, Africa, Europe, and has also increased health risks such as the spread of infectious diseases, disease spectrum, and lifestyle changes, posing challenges to the development of global health in China. Based on the history of global health, this paper made a brief review of the current status and future development of global health research. It pointed out that China’s global health research started late and had many shortcomings. In the context of the One Belt And One Road initiative, We should seize opportunities and meet challenges to contribute to the construction of "Healthy China" and the promotion to global health.

Objective To investigate the differences in the epidemiological characteristics of patients in pre-hospital medical care before and after “5 · 12” Wenchuan earthhquake in Deyang city.Methods Comparison was made between the epidemiological features of cases treated in Deyang emergency medical center from the January 1,2007 through the December 31,2007 before the earthquake (the pre-earthquake group) and those treated from the January 1,2009 through the December 31,2009 after the earthquake ( the post-earthquake group) with the criteria of international classification of diseases (ICD-10).Results ( 1 ) There were 11 325 patients medically cared before earthquake and 16 265 patients after disaster.The distribution of sex,age,the top five causes,the seasonal and diurnal variations of emergency call,radius of service circle of pre-hospital medical care cases were no significantly different between the two groups ( P ＞ 0.05 ).( 2 ) The time required for scheduling ambulance and time consumed for the transportation of patients in the post-earthquake group were less than those in the pre-earthquake group ( P ＜ 0.05 ).Conclusions The efficiency of medical care done by 120 Emergency Command Center in Deyang city has been improved significantly in ease of without change in epidemiological features of patients after reconstruction of disaster area.

Objective To construct recombinant plasmids containing HPV18E7 gene ,and explore the optimization condition of its expression in Escherichia coli .Methods The genomic DNA extracted from HeLa cell line which served as a template to the HPV18 E7 gene was amplified using PCR method ;and the amplified product of HPV18E7 gene was connected to the pET-32a(+ ) vector ,which composed the pET-32a(+ )-HPV18E7 recombinant plasmid ;the positive recombinant plasmids were transformed into BL21-DE3-pLysS competent cells and the optimized expression condition was explored in order to obtain a large amount of HPV18E7 oncogenic protein .Results The fragment length of PCR products of HeLa cell genomic DNA was consistent with that of HPV18 E7 gene .In LB medium ,the expression level of the target protein was not high under such conditions as different concentra-tion of IPTG and lactose ,different temperatures and different induction starting amount .Therefore the ZYM-5052 auto-induction medium was tried in this experiment ,and the expression amount of the fusion protein was much higher than that induced with IPTG and lactose .Conclusion The amount of HPV18E7 fusion protein in ZYM-5052 automatic induction medium is much higher than that induced with IPTG and lactose .

The tissue-specific and MeJA-induced transcriptional levels of BcUGT3 and BcUGT6 in Bupleurum chinense were analyzed in the present study. The transcriptional levels of BcUGT3 in root, leaf, flower and fruit were similar and they all were higher than those in stem. The transcriptional level of BcUGT6 was the highest in leaf and the lowest in flower among in all tested tissues. With non-treated adventitious roots as control, BcUGT6's transcriptional levels were elevated to nearly 2 folds for 2 h, 8 h, 24 h, 2 d and 4 d in MeJA-treated adventitious roots of B. chinense. It showed that the transcriptional level of BcUGT6 was slightly affected by MeJA. While, BcUGT3's transcriptional levels were gradually elevated, and till 4 d after MeJA treatment, the expression level was about 7 folds than that of non-treated control. Using pET-28a (+), the expressions of two genes was investigated. Induced by IPTG, the target proteins were expressed in E. coli and then purified. All the results obtained in the present study will be helpful for follow-up bio-function analysis of BcUGT3 and BcUGT6.
