OBJECTIVETo compare the differences on onset timing of acute ST segment elevation myocardial infarction (STEMI) in young and aged patients.
METHODSThe exact onset time of symptoms was obtained from 1024 consecutive patients with STEMI admitted to our hospital between January 2000 and May 2010. Patients were classified as the middle-aged group [< 65 years old, mean (52.2 ± 8.0) years, n = 536] and old group [≥ 65 years old, (72.2 ± 5.5) years, n = 488], the difference of the onset months, weeks, weekdays and hours between two groups was compared.
RESULTSThe high onset timing of STEMI in middle-aged group was October and February, Friday, Saturday and Wednesday, at 10 A.m. and 10 P.m. The high onset timing of STEMI in old group was October, January and March, Friday, Sunday and Monday, at 6 A.m. and 2 A.m. The incidences of STEMI in the old group were significant higher than in the middle-aged group in March (11.89%), on Sunday (15.97%) and Monday (17.42%), at 6 A.m. (6.35%) and 2 A.m. (5.74%) (all P < 0.05) while the onset rate was significant higher in February (9.89%), On Saturday (16.98%), At 8 P.m. (4.86%) and 10 P.m. (5.78%) in the middle-aged group than old group (all P < 0.05).
CONCLUSIONThe onset timing of STEMI in old patients was significant different from the middle-aged patients suggesting the onset timing of STEMI changes with aging.

BACKGROUNDKeyhole surgery has developed since the 1990s as a less invasive therapeutic strategy for intracranial lesions, initially for the treatment of intracranial aneurysms. The purpose of this study was to describe and evaluate the results of surgical treatment of lesions in the anterior fossa and sellar region via a supraorbital keyhole approach using eyebrow incisions.
METHODSBetween April 1994 and July 2003, 54 patients with lesions in the anterior fossa and sellar region were operated on via the supraorbital keyhole approach. The surgical results were studied retrospectively and compared with that of patients with lesions at the same locations but treated via a conventional subfrontal approach.
RESULTSNo significant difference in curative effect was found between the conventional subfrontal approach and the supraorbital keyhole approach. However, the supraorbital approach required a much smaller skin incision, causing less surgical trauma, while achieving excellent surgical exposure and good recovery.
CONCLUSIONThe supraorbital keyhole approach using an eyebrow incision is safe, effective, and both suitable and convenient for treating lesions in the anterior fossa and sellar region, with almost no adverse consequences on the facial features of patients.

OBJECTIVE:
To examine the normal range of the width of posterior cranial fossa (WPCF) in the second and third trimester by ultrasonography, and to investigate its relationship with fetal congenital and chromosome abnormality.
METHODS:
WPCF of 2484 fetus (gestational age from 14 to 41 weeks) was measured by ultrasonograph routinely, and the infants were followed up.
RESULTS:
In 2848 fetus, 2772 were normal and 76 were abnormal. WPCF increased before 32 weeks, decreased after 33 weeks, the largest value of WPCF was 13.4 mm. The occurrence rate of WPCF> or =8 mm in normal fetus was 8.84%, and that in abnormal fetus was 17.46%. Most fetuses with chromosome abnormality had normal WPCF in the second trimester, but some fetuses with remarkable broadening in the late stage. Some abnormal fetuses (such as water head, Dandy-Walker's syndrome etc) showed significant extension of WPCF.
CONCLUSION
WPCF increases before 32 weeks, decreases after 33 weeks;and can be easily measured during 29 - 32 weeks. WPCF of some fetus with chromosome abnormality or with congenital abnormality is remarkably broadened in the late stage. The fetus of WPCF> or =10 mm should be followed up closely, and antenatal diagnosis should be done if WPCF is more than 14 mm.

BACKGROUND: A Lenke3 type adult idiopathic scoliosis finite element model was established successfully using Mimics software. However, whether the model fits the actual conditions of individualized patients still requires a further revision and validation.OBJECTIVE: To modify and validate the Lenke3 type adult idiopathic scoliosis finite element model by finite element analysis software.METHODS: Based on the characteristics of Lenke3 adult idiopathic scoliosis model, the three-factor and three-level orthogonal experiment was used to optimize the finite element model, making it more close to the actual one. The vertebrae at T1-T4, T5-T8 and L6-S1 levels (sacral lumbarization) were loaded to simulate left and right lateral flexion,as well as extension and flexion, and the range of motion when left and right rotation were compared with Busscher and Yamamoto experiments in vitro.RESULTS AND CONCLUSION: (1) According to the orthogonal experiment, the mean difference and range of each factor and each level were calculated, and finally A1B2C3 combination was the optimal one that can make the model largely consistent with the real situation. The difference in Cobb angles between the clinical lateral flexion test and the parameter pre-modified model simulation was 54.44°, which was decreased to 2.11° after modification. Moreover, the maximum difference in each scoliosis Cobb angle of the modified model was 4.29°. (2) The simulation results of the modified model when compared with the X-ray images when left and right lateral flexion, the two data obeyed normal distribution, so the paired t test was used: left lateral flexion, P =0.082 (P > 0.05); right lateral flexion, P=0.421 (P > 0.05);supine position, P=0.160 (P > 0.05). (3) The range of motion at T1-T4 segments was as followings: left flexion, 3.25°;right flexion, 3.32°; anteflexion 2.52°; extension, 2.89°; left rotation, 3.73°; right rotation 3.76°; the range of motion at T5-T8 segments: left flexion, 1.39°; right flexion, 1.43°; anteflexion 1.35°; extension, 1.34°; left rotation 2.09°; right rotation 2.11°; the range of motion at L6/S1: left flexion: 5.17°; right flexion: 5.19°; anteflexion: 8.92°; extension: 7.35°; left rotation: 1.41°; right rotation: 1.42°. The results were almost consistent with Busscher and Yamamoto experimental results. (4) To conclude, the model is in good agreement with the patient's actual properties after modification. The modified model has good reliability and validity, and provides valid data platform for simulating clinical operation in the future.

OBJECTIVETo investigate the effects of Vaspin on lipopolysaccharide (LPS)-induced acute respiratory distress syndrome (ARDS) in mice and explore the possible mechanism.
METHODSForty male C57B/L6 mice were randomized equally into control group, LPS group, Vaspin group and wortmannin group with corresponding treatments. The pathological changes of the lung tissues were evaluated by HE staining, and the severity of pulmonary edema was measured according to the wet/dry ratio (W/D) of the lung tissue. The lung permeability was evaluated by detecting total protein concentrations in the bronchoalveolar lavage fluid (BALF) using bicinchoninic acid (BCA) assay. Myeloperoxidase (MPO) activity in the lung tissue was detected using a MPO assay kit, and the levels of interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) in the lungs were measured using ELISA. Immunohistochemical staining was performed to detect the expression of vascular cell adhesion molecule-1 (VCAM-1) and Western blotting was used to detect the protein expressions of cleaved caspase-3 and p-Akt in the lung tissues.
RESULTSCompared with the control group, the mice in LPS group displayed typical ARDS pathological changes in the lungs with significantly increased W/D, total protein concentrations in BALF, lung MPO activity, levels of IL-1β and TNF-α, and pulmonary expressions of VCAM-1 and cleaved caspase-3 (P<0.05) but decreased expression of p-Akt (P<0.05). These changes induced by LPS were significantly alleviated by the administration of Vaspin (P<0.05). The protective effects of Vaspin against ARDS were obviously attenuated by the PI3K inhibitor wortmannin (P<0.05).
CONCLUSIONVaspin protects against LPS-induced ARDS in mice possibly by inhibiting inflammation and protecting vascular endothelium through upregulation of the PI3K/Akt signal pathway.
