Objective To investigate the mechanisms of enophthalmos and deformities of orbital walls in patients with orbital blowout fracture and to evaluate the reconstructive surgical methods. Methods The features of orbital deformities, the change of orbital volume and the mechanisms of enophthalmos were measured and analyzed by means of 3-D CT technique and 3-D diagnostic computer-assisted system. The reconstructive operations were employed on these 11 cases with orbital blowout fractures to correct deformities and restore orbital volume by applying autogenous bone grafts or hydroxyapatite bone substitutes. Results There were no serious complications such as infection of bone graft, exposure of hydroxypatite implant in all 11 cases, 10 cases got satisfactory appearance of eyelids and orbit, of which thediplopia and enophthalmos were corrected with protrution of eyeball restoring normally. 1 case remained diplopia after surgical correction. Conclusions The enophthalmos is mainly caused by orbital volume enlarging and orbital content herniating into paranasal sinuses. Implanting autogenous grafts and hydroxyapatite substitutes to restore orbital volume are proved to be effective.

Congenital heart disease is one of the most common birth defects, which is the main cause of death in children.Cardiovascular development is a complex process involving multiple genes, signaling pathways and regulatory factors.According to the sequencing of human genome and encode project, more than 80% of the genes in the genome are transcribed, but only 3% of these transcripts correspond to protein-encoding RNA.It is pointed out that non-coding RNA is as important or even more important as encoding RNA.More and more evidences show that not only encoding genes are involved in the regulation of cardiovascular development, but also protein non-coding genes play an important role in the development of heart.This review will summarize the biological characteristic and function of long noncoding RNAs, and introduce the role of some representative lncRNA in heart development and congenital heart disease.

Objective To estimate relationship between the brain atrophy rate and percent corpus callosum area change in patients with cerebral vascular disease.Methods Forty-six patients with cerebral vascular disease underwent MR scanning twice,at the baseline and at the end of the follow-up period.T1W images at both time points were processed automatically with structural image evaluation using normalization of atrophy(SIENA) software to determine the percent brain volume change(PBVC).In addition,the corpus callosum and the inner table of the skull on the mid-sagittal images of two scans were outlined manually to measure their areas.The percent of corpus callosum area change(PCCAC) was calculated.Then,the relationship between PBVC,PCCAC and age was statistically analyzed.Results Significant correlation was found among the three variables: spearman rank correlation coefficient was-0.295 for PBVC and age(P=0.047),while it was-0.4 for PCCAC and age(P=0.006),and 0.538 for PBVC and PCCAC(P=0.000).Conclusion SIENA software identifies brain atrophy quantitatively in patients with cerebral vascular disease,which correlated with area reduction of the corpus callosum.

It is crucial to improve the health care quality during the progress of constructing the new health care system in both urban and rural area.On the condition of increasing government commonweal investment for the basic health care,the standardized training program for the district medical practitioners will become the pivotal step to improve district health care in urban and rural area,standardize medical service,reduce the medical cost and optimize the accessibility to medical care for the mass.Taking the consideration on the personal resource of district medical service in the urban and rural area in China,certain strategic proposals related to the standardized training program for the fundamental medical practitioners are discussed.

OBJECTIVETo study the blood enriching effects of Paeoniae Radix Rubra and Paeoniae Radix Alba, paeoniflorin and albiflorin on mouse model of blood deficiency caused by γ-ray radiation.

METHODBuild mouse model of blood deficiency induced by γ-ray radiation. Paeoniae Radix Rubra and Paeoniae Radix Alba were given during modeling. The amount of WBC was detected af- ter the treatment. Based on the result of WBC and paeoniflorin content, albiflorin content in Paeoniae Radix Rubra and Paeoniae Radix Alba, the same model and the same method were used to comparatively study the effect of blood enriching of paeoniflorin and albiflorin.

RESULTOn the 7th day, the amount of WBC in model mice treated with 2 g x kg(-1) Paeoniae Radix Alba and 2 g x kg(-1) Paeoniae Radix Rubra significantly increased compared with that of model group (P < 0.05). In another experiment with the same model, the amount of WBC in model mice treated with 120 mg x kg(-1) paeoflorin and 120 mg x kg(-1) albiflorin significantly increased (P < 0.05) compared with that of model group on the 7th day. On the 10th day, the amount of WBC in rats treated with 120 mg x kg(-1) paeoflorin increased significantly (P < 0.05) compared with that of model group. Compared with the same dose of paeoniflorin, the amount of WBC in mice treated with albiflorin had no significant difference.

CONCLUSIONAll Paeoniae Radix Alba, Paeoniae Radix Rubra, paeoniflorin and al- biflorin can raise the amount of WBC and have the effect of enriching blood induced by radiation, while paeoniflorin and albiflorin have a similar result in this model. The result indicated that both paeoniflorin and albiflorin are effective constituents in Paeoniae Radix Alba, and paeoniflorin work as the common effective constituent in both Paeoniae Radix Rubra and Paeoniae Radix Alba.

OBJECTIVETo investigate clinical outcomes of tendon allograft reconstruction with arthroscopy minimally invasive technique at stage I for the treatment of knee dislocation with multiple ligaments injury.

METHODSForty-eight patients with knee dislocation were reconstructed anterior and posterior ligament under arthroscopy at stage I from January 2008 to January 2012, and repaired ligaments injury of knee joint by minimally invasive technique. There were 38 males and 10 females aged from 20 to 59 years old with an average of 35.6 years old; 22 cases on the left side and 26 cases on the right side; the time from injury to operation ranged from 2 d to 2 weeks. Two cases combined with anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), medial collateral ligament (MCL) and posterolateral complex injuries, 36 cases combined with ACL, PCL, and MCL injuries, 10 cases combined with ACL, PCL and PLC injuries; 4 cases combined with peroneal nerve injury. Lysholm scoring were used to compared the cases before operation and final following-up to evaluate knee function.

RESULTSAll patients were followed up from 12 to 30 months with an average of (18.2 ± 6.3) months. Activity and stability of joint were obviously improved. Lysholm score were improved from 40.3 ± 4.1 before operation to 87.0 ± 6.4 at final following-up.

CONCLUSIONReconstruction with arthroscopy minimally invasive technique at stage I for the treatment of knee dislocation with multiple ligaments injury could recover stability of joint better,reserve joint function. Preoperative training and postoperative individualized rehabilitation treatment is the key point of recover knee joint function.

AIM:To investigate the effect of hirsutine on hypoxia-induced migration and invasion abilities of human breast cancer MCF-7 cells and its possible mechanism. METHODS:CCK-8 assay was employed to detect the cyto-toxic effect of hirsutine on the MCF-7 cells. Cell migration was observed by wound healing assay,and cell invasion ability was measured by Transwell invasion assay. Western blot was used to analyze the protein levels of hypoxia-inducible factor-1α(HIF-1α),Snail,E-cadherin and matrix metalloproteinase-9 (MMP-9). The mRNA levels of HIF-1α was detected by RT-PCR. RESULTS:Hirsutine remarkably reduced the cell viability from 32 μmol/L(P<0.05),and the IC50value was 62.82 μmol/L. In hypoxia state,MCF-7 cells showed more powerful capabilities of migration and invasion (P<0.05), higher protein levels of HIF-1α,Snail and MMP-9 (P<0.05),lower protein level of E-cadherin(P<0.05),and higher mRNA level of HIF-1α (P<0.05). These hypoxia-induced effects were all inhibited by hirsutine at 16 μmol/L (P<0.05),apart from the mRNA level of HIF-1α. CONCLUSION:Hirsutine inhibits hypoxia-induced migration and inva-sion in human breast cancer MCF-7 cells most likely via down-regulation of the protein levels of HIF-1α,Snail and MMP-9,and up-regulation of the protein level of E-cadherin.
