Objective To study the early diagnosis and treatment of traumatic diaphragmatic hernia(TDH). Methods Retrospective analysis of the clinical data of 23 cases of TDH was made. Result 12 cases(51%) were preoperatively diagnosed,10 cases(43.5%) misdiagnosed,1 case was misdiagnosed during exploration laporatomy. 20 cases(86.9%) were cured and 3(13.1%) died. 1 case died of toxic shock because of misdignosis resulted in intestinal strangulation. Conclusions Increasing knowledge, dynamic observation of the disease and X-ray, promptly exploration can reduce the rate of misdiagnosis of TDH. With early diagnosis and treatment, most cases of TDH can be cured. The main cause of the death results from delayed diagnosis and treatment, and not related to TDH itself.

Objective Objective To study the feasibility of direct applying MRI to TPS by measuring the geometric distortion of MRI. Methods Phantom 1 was made by marking radical arrangement of fat pipelines every 15? in foam phantom and Phantom 2 by net arrangement at every 2.7?cm. Coronal and transverse scan parallel with the radial and net fat pipeline in the phantom was performed at sequence of cranial FSE T2WI by Marconi 1.5T superconduct MRI machine. Geometric distortion in 5 different fields of view (FOV) was calculated by measuring the absolute borderline error of direct scan and coronal digital reconstructed radiograph (DRR). Results When FOV was equal or smaller than 11.0?cm?11.0?cm, 22.0?cm?22.0?cm and 27.5?cm?27.5?cm, the geometric distortion was 0.0, 1.1 and 1.4?mm of direct scanning MRI and 1.0,1.4 and 2.0?mm of coronal DRR. Conclusion When the magnetic field of MR is high and the tissue shows uniform density, MRI can be applied on TPS directly.

Objective To evaluate the imaging quality and radiation doses of dual-source computed tomography (DSCT) coronary angiography at a low tube voltage in patients with medium and low heart rate.Methods Eighty-five patients[heart rate (HR) ＜ 91 beats per minute (bpm); body mass index (BMI) 17. 51-30. 00 kg/m2]suspected of coronary artery disease received retrospectively ECG-gating coronary angiography with dual-source CT scanner (Somatom Definition, Siemens) at a tube voltage of 100 kVp. For all patients, no beta-blocker was used before CT scan. According to the HR, the patients were divided into three groups: Group A, HR ≤ 59 bpm, n = 27; Group B, HR 60-69 bpm, n = 29; Group C,HR ≥70 bpm, n = 29. All images were transferred to a workstation for postprocessing. The best R-R interval reconstruction images of all groups were evaluated. The value of pitch, CT volume dosage index (CTDIvol), dose length product (DLP)and effective dose (ED)were recorded. The pitch, the score of imaging quality of coronary artery segments and the radiation dose were compared with one-way ANOVA. The influence of HR on image quality and radiation doses of coronary artery was analyzed. Results The value of pitch in Group A, Group B and Group C was 0. 241 ± 0. 025, 0. 286 ± 0. 034 and 0. 335 ± 0. 036,respectively. The mean score of imaging quality of coronary artery segments in Group A, Group B and Group C was 4. 78 ± 0. 26, 4. 66 ± 0. 56 and 4. 70 ± 0. 46, respectively. The value of CTDIvol in Group A,Group B and Group C was (18.06 ±5. 16), (19. 62 ±7. 15) and (17. 50 ±7. 13) mGy, respectively. The value of ED in group A, Group B and Group C was (4.23 ± 1.76), (4.59 ± 1.75) and (4.12 ±1.39) mSv, respectively. There was statistical difference in value of pitch among the three groups (F =60. 00, P= 0. 00). There were no statistical difference in score of imaging quality, CTDIvol and value of ED among the three groups (F = 0. 53, P = 0. 59; F = 0. 83, P = 0. 44 ; F = 0. 86, P = 0. 43). Conclusion Medium and low HR have little influences on image quality of dual-source CT coronary angiography at a low tube voltage. When the auto ECG-gating is selected, there is little influence on radiation dosage as well.

Traumatic brain injury (TBI) is a common disease in neurosurgery.Cognitive impairment is one of the most common and long-lasting complications after TBI.Recent studies have shown that computer-assisted cognitive rehabilitation has become an important means for the rehabilitation of cognitive impairment.The authors intend to review the status of computer-assisted cognitive rehabilitation training for cognitive dysfunction after TBI.

BACKGROUND:It is unclear whether short-term high-intensity interval training (HIT) can be used to protect against myocardium injury after acute myocardial infarction, as wel as the underlying mechanism.
OBJECTIVE:To observe the effects of short-term HIT on the ventricular remodeling and mitochondrial content after acute myocardial infarction, and the biological effect of mitochondrial biogenesis and autophagy in this process.
METHODS:Male Sprague-Dawley rats were modeled into acute myocardial infarction by ligating coronary artery. One week later, HIT was performed:each interval consisted of 4-minute high-intensity running (80%of maximal oxygen consumption) and 3-minute active recovery (40%of maximal oxygen consumption), for 4 consecutive weeks of 5 days each week, repeated 7 cycles.
RESULTS AND CONCLUSION:Four-week HIT after acute myocardial infarction could markedly enhance left ventricular pump function and mitochondrial content, improve mitochondrial membrane potential and ATP synthetic activity, inhibit mitochondrial reactive oxygen species generation, up-regulate PGC-1α/Tfam induced mitochondrial biogenesis and Bnip3/Beclin-1 induced autophagy. These results indicate that short-term HIT can improve normal mitochondrial content after acute myocardial infarction, which in turn ameliorates myocardial systolic property and energy metabolism. As a cardiac rehabilitation method, HIT exhibits fine timeliness.

Background and purpose: The previous work of this study has showed that the treatment of liver cancer cells with emodin could induce endoplasmic reticulum (ER) stress and apoptosis. Given the cross-talk between ER stress and autophagy, this study aimed to investigate whether blockage of autophagy, a defense mechanism against environmental stress, could improve the killing effect of emodin on liver cancer cells. Methods: The CYTO-ID auto-phagy detection kit and Western blot were used to determine autophagy in liver cancer cells. After combined treatment with chloroquine (CQ) and emodin, cancer cell survival was analyzed by ATPlite assay and clonogenic assay. Apoptosis was detected by both flow cytometry analysis and Western blot. Results: Autophagy could be induced in liver cancer cells after treatment with emodin. Inhibition of autophagy significantly increased growth-inhibitory effect of emodin on both HepG2 and Huh7 cancer cells. The combination treatment with CQ and emodin promoted remarkable apoptosis in liver cancer cells, evidenced by the increase in the percentage of cells in sub-G1 phase and the higher expression lever of cleaved caspase-3. Conclusion: Therapeutically targeting autophagy is capable of enhancing cytotoxicity of emodin in liver cancer cell lines.
