Objective:To analyze essential health care equity in cities and counties of Hainan in order to provide the basis for its development. Methods:Based on health statistics of Hainan, China and OECD countries, indicators of essential health care equity in cities and counties were analyzed. Results:Equity in distribution of resources, the hospi-tal geographical distance is large difference, physician-to-nurse ratio is 1:1. 2, and the Gini coefficient is more than 0. 3. Equity in financing, health care spending per capita is less than the national level. Cities and counties with high government budgets for health are located in regional centers. The hospitalization costs compensation with new rural co-operative medical scheme is about 50%. Equity in service supply, bed occupancy rate below 90% and drugs accounted for 30% ~40% in most cities and counties. Regional differences in maternal and child health management are small, but below the national level. Conclusions:The situation of essential health care resources is related to the political and economic climate. Financing mechanisms for essential health care are imperfect;and a low supply of basic medical and public health services reduced the quality of essential health care. Suggestions:Rational distribution of essential health care resources should be promoted;essential health care financing should be increased;and the capability of essential health care supply should be improved.

Objective To systematically review the existing evidence about the effect of medial and lateral (crossed) entry pins versus only lateral entry pin fixation on the supracondylar fractures of the humerus in children.Methods Eligible studies were identified in Cochrane library,the Cochrane Bone,Joint and Muscle Trauma Group (till March 2011 ),Medline (from 1966 to March 2011 ),EMbase (from 1966 to 2011 ),CBM (from January 1979 to March 2011 ),PubMed,Wanfang Data (from 2000 to March 2011 ) and CNKI and the references of the included studies and several Chinese orthopedic journals were manually searched.Then,the randomized controlled trials (RCTs) and quasi-randomized controlled trials (CCTs) about two entries (crossed and only lateral pinning) for supracondylar fractures of humerus in children were collected.After evaluation of methodology with the enrolled studies,available data was extracted and systematic review was conducted via the method recommended by the Cochrane Collaboration.Results In total,five RCTs involving 311 patients were involved.Compared with the preoperative data,the meta-analysis results showed no significant difference in reduction stability in terms of change in Baumann angle and Carrying angle between the two groups.For the postoperative function outcome including complete reduction,Flynn grade and full return to function,no significant difference was found between the two groups.For the postoperative complications,there was no difference in the infection of pin tract,though lateral entry resulted in a significant lower incidence of the iatrogenic nerve injury compared with the medial and lateral entry.Conclusions With the Kirschner wire fixation for supracondylar fractures of humerus in children,current existing evidences indicate that the lateral entry of pinning has similar results in reduction stability,function outcome and incidence of pin tract infection compared with medial and lateral entry.Nevertheless,lateral entry,as a safe pinning technique,may effectively decrease the risk of iatrogenic nerve injury

Objective To study the efficacy of radical surgery for the invasion of chest wall by lung cancers and the different methods of chest wall reconstruction. Methods A retrospective analysis of clinical data was conducted in 27 cases of lung cancer with chest wall invasion in this hospital. 24 cases received lobectomy, 3 cases received pneumonectomy, and all cases received wall reconstruction. The size of chest wall defect after resection ranged from 6.5 cm × 5.4 cm × 5.0 cm to 15.5 cm × 12.5 cm ×10.0 cm. The number of rib resection for each patient ranged from 1 to 4. The reconstructive methods were as follows: using polyester fabric to reconstruct costal pleura, using plexiglass, stainless steel wire and grid-like titanium plate to reconstruct bone defect, and using nearby muscle flap and pedunculated muscle flap to reconstruct muscle defect. Results Pathologic diagnosis was non-small cell lung cancer,including 22 cases of squamous cell carcinomas and 5 adenocarcinomas. There were pulmonary infections in 6 cases, chest hemorrhage in 1 case and chest purulence in 1 case. One-year survival was 77. 9 %,3-yearsurvival was 58.3 %, and 5-year survival was 29. 1 %. Conclusion The lung cancer with chest wall invasion is advisable to make active use of radical surgery. The different methods and repair materials are chosen to reconstruct the chest wall defect, supplemented by comprehensive treatments.

Objective To observe the effects of low frequency electrical stimulation (LFES) on the proliferation of endogenous brain neural stem cells (NSCs) and on the expression of basic fibroblast growth factor (bFGF)and epidermal growth factor (EGF) in rats with acute cerebral infarction; to explore the therapeutic mechanism of LFES in improving neural function. Methods Fifty-four rats were randomly divided into a LFES group, a placebo stimulation group and a sham-operated group. Each group was further divided into 3rd day, 7th day and 14th day subgroups, with 6 rats in each subgroup. An acute cerebral infarction model was induced in the rats of the LFES and placebo stimulation groups by middle cerebral artery occlusion (MCAO). Three days after the operation, rats in the LFES group began LFES treatment (frequency 30 Hz, pulse width 250 μs, current intensity 3 mA, 10 min/d) ,while the placebo stimulation group was treated identically but without electricity. The rats in the sham-operated group had no special treatment. The expression of nestin positive cells in the subgranular zone of the hippocampus and the subventricular zone was detected by immunohistochemical staining. The expression of bFGF, EGF proteins and mRNA in the ischemic hemisphere was detected by Western blotting and RT-PCR analysis. A screen test was applied to evaluate motor function. Results Nestin-positive cells in the subgranular and subventricular zones of rats in the LFES group increased significantly more than in the placebo stimulation group at the 7th and 14th day. The expression of bFGF, EGF proteins and mRNA in the ischemic hemisphere was up-regulated compared to the placebo stimulation group at the 7th and 14th day. At the 14th day a difference in motor function was observed in rats in the LFES group compared with the placebo stimulation group. Conclusion LFES can promote the proliferation of endogenous brain NSCs and the expression of bFGF and EGF in rats with acute cerebral infarction. It can also improve motor function and enhance neural plasticity in the brain.
