OBJECTIVE: There are some people in population susceptible to acute mountain sickness. Therefore, it is important to analyse, assess and integrate certain research results to build prediction system and mathematics model in order to predict those susceptible people when army goes to tableland.DATA SOURCES: Computer was used to search databases such as Medline, PubMed and PML to find articles regarding prediction of people susceptible to acute mountain sickness from January 1970 to December 2002 with the search words "acute mountain sickness, susceptible population,prediction" . The language was limited to English. At the same time, Chinese Journal Full-text Database, Chinainfo and CBMdisc were searched to find articles from January 1970 to August 2004 by the Chinese language of "acute mountain sickness, susceptible population and prediction". The research targets are susceptible people to acute mountain sickness. At last,trace-back method was used to supplement some literature and monographs.DATA SELECTION: After systematically analyzed and concluded the literature information and screened researches without conducting experiment, full text of the rest literature was searched and used as selective criteria if it could be used as prediction indicator of susceptible people to acute mountain sickness.DATA EXTRACTION: Totally there were 19 prediction indicators generalized. After conducting systemic analysis, Delphi method and analytic hierarchy process(AHP) to the indicators, 13 were selected while the other 6 were excluded.DATA SYNTHESIS: The indicators were classified according to nervous-humoral regulation ability, oxygen capture ability of respiratory system,anti-anoxia ability of central nervous system, mental health and health service ability. Based on these, system analysis, Delphi method and AHP method were used to screen prediction indicators, establish indictor system, confirm the weighted indicators and weighted indicator system as well as standardize the prediction indicators.CONCLUSION: According to the principle of prediction model and model methods, weighted linear synthesis method was used to build the predictive mathematic model. The project of susceptible population prediction of acute mountain sickness in army when entering tableland urgently was proposed combining the health service ability of army.

Objective To explore the effect of repetitive transcranial magnetic stimulation (rTMS) on motor function in cerebral palsy children with epilepsy. Methods 270 cerebral palsy children with epilepsy hospitalized from February, 2011 to September, 2014 were ran-domized to control group (n=130) and treatment group (n=140). The control group received comprehensive rehabilitation, including mas-sage, exercise, occupational therapy, physiotherapy, speech training, cognitive function training and medication, and the treatment group re-ceived rTMS in addition. They were assessed with Gross Motor Function Measure-88 (GMFM-88) and Peabody Developmental Measure Scale-Gross Motor (PDMS-GM) before, and 1 and 2 months after treatment. Results The total scores of GMFM-88 and PDMS-GM in-creased more in the treatment group than in the control group (F>93.9, P<0.001). Conclusion rTMS can further improve the motor function in cerebral palsy children with epilepsy.

An innovative approach,named associating liver partition and portal vein ligation for staged hepatectomy (ALPPS),has made possible a marked increase in future liver remnant (FLR) over a short period of time,and has challenged the concept of unresectability.To date,ALPPS has been employed for a variety of primary and metastatic liver tumors from many centers across the world.Many technical variations of ALPPS have been described.However,much controversy has surrounded this procedure,and many problems remain to be solved,such as the reasons for rapid hypertrophy,the technical feasibility,safety and long-term oncologic outcomes,and the result compared with the conventional two-stage hepatectomy.These aspects are needed to be evaluated further in large-scale studies.We believe that the ALPPS procedure will has much room for further development.

BACKGROUND:With elevated medical levels, limb salvage surgery for limb malignant tumor is valuable day by day. At present, the limb salvage surgery has substituted amputation and becomes mainstream and development direction of present surgical treatment of limb tumors. However, so far, there are no unified surgical indications for proximal femur tumor, which are controversial. OBJECTIVE:To investigate the efficacy of artificial total hip arthroplasty combined with extended resection of tumor sections for proximal femoral bone tumors. METHODS:Patients with proximal femoral bone tumors in the Second Xiangya Hospital of Central South University were selected and divided into control group and observation group, with 30 patients in each group. According to the disease, lesion curettage, aneurysm wal inactivation, autologous and (or) al ogeneic bone, mixed bone graft and bone graft fixation were selected to treat the control group. The observation group patients received extended resection of tumor sections and total hip arthroplasty. The operative time, intraoperative blood loss, hospital stay and joint function of two groups were compared. 2 years later, patients were revisited. Metastasis and recurrence rate, death rate and quality of life of two groups were compared. RESULTS AND CONCLUSION:There was no significant difference in intraoperative blood loss and surgery time between the two groups (P>0.05). However, hospital stay of patients in the observation group was shorter than the control group. The excellent and good rate of recovery of joint function (83%) was higher in the observation group than in the control group (53%). The metastasis and recurrence rate within 2 years after surgery (7%) and death rate (3%) were lower in the observation group than in the control group (30%, 23%). Various indicators of quality of life of patients in the observation group were significantly better than the control group (P<0.05). These results confirmed that artificial total hip arthroplasty in the treatment of proximal femur tumors is safe and effective.

Colorectal cancer (CRC) is one of the most common digestive system neoplasms in China. Recently, the morbidity and mortality rates of CRC continue to increase with the improvement of people's living standard and the change of the dietary structure. It was accepted that the etiology of colorectal cancer is a multi-factor and multi-step process. However, the mechanism of CRC is still unclear. MicroRNAs (miRNAs) are a class of -21 nucleotide non-coding RNAs and function as a negative regulator of gene expression after transcription, participating in tumor angiogenesis, tumor cell proliferation and invasion. MicroRNA-21 (miR-21), as an important oncogenic RNA, plays a vital role in the development and progression of CRC. This review summarizes the advances in research on miR-21 in colorectal cancer.
