Objective To compare the propagation speed and physical parameters between underwater blast wave and air blast wave. Methods The physical parameters of blast wave were measured by PCB pressure transducers (USA) during underwater and air explosions of 200g, 500g and 1000g TNT respectively. Consequently, the propagation speed, peak overpressure value, positive duration and impulse of blast wave were analyzed. Results Underwater blast wave was characterized by high propagation speed, high peak overpressure value, great impulse, however, short duration. Compared with air blast wave, the propagation speed of underwater blast wave was 3.70-4.30 times higher than that of air blast wave, the peak overpressure value was 227.15-247.86 times higher, and the impulse was 8.48-11.80 times greater than that of air blast wave. Conclusion Underwater blast wave propagates faster than that air blast wave. Meanwhile, it also peoduces higher peak overpressure value and impulse. This result is helpful for the evaluation of injury severity and treatment of underwater blast injury.

ObjectiveTo investigate the effect of early intervention on shoulder pain in patients with hemiplegia after stroke. MethodsStroke patients were treated with bedside physical therapy on the shoulder 7 d after onset. They were assessed with short-form McGill pain questionnaire and Fugl-Meyer assessment of upper extremity before and 40 d after treatment. ResultsThe score of MPQ in the treatment group was significantly lower than that in the control group, while the score of FMA was significantly higher(P<0.01). ConclusionEarly intervention can reduce the pain and improve the function of the shoulder in patients with shoulder pain after stroke.

ObjectiveTo evaluate the efficacy and safety of Sirolimus (SRL) in immunosuppression following liver transplantation. Methods SRL was applied in 21 patients totally.Indication for adoption was Tac-related nephrotoxicity (4/21), suspiciously Tac-related hepatoxicity (8/21), Tac overdose (3/21), renal insufficiency pre-operation (2/21), or cancer (4/21). Median follow-up was 25. 4 months. Results SRL provided an adequate prophylaxis against rejection in all study patients, with one case of acute rejection. Sirolimus was Withdrawn in 2 cases due to its sideeffect. Tat-induced hepatoxicity in 6 cases and nephrotoxicity in 3 cases were relieved significantly.Conclusions SRL given alone appears to be an effective primary immunosuppressant regimen fororthotopic liver transplantation patients. Early conversion contributes to significant improvement of Tac-related hepatoxicity and nephrotoxicity.

Objective To study the engraftment syndrome (ES) and the possible etiology after haploidentical allognneic hematopoietic stem cell transplantation (al]o-HSCT). Methods The clinical manifestation, treatment and outcome of a chronic myeloid leukemia patient who after allo-HSCT were presented. Results The patient started to cough on day 2 after allo-HSCT, dry cough at beginning, white foam sputum, non-infectious fever, fluid retention, weight gain, transient encephalopathy on day 4. The clinical symptoms were improved after treatment with corticosteroids, in which ES was diagnosed. Conclusion ES is a series of clinical syndromes following transplantation which is different from acute graft versus host disease. It occurred after HSCT, and corticosteroids are often effective. Therefore early recognition and accurate diagnosis is very important.

The on-line monitor for the changes in the content of baicalin in Scutellariae Radix formula particles during the extraction process was conducted by using near infrared spectroscopy (NIR). High performance liquid chromatography (HPLC) was used as a reference method. Kennard-Stone (KS) was used to divide sample sets, so as to compare different pretreatment methods. The synergy interval partial least squares (SiPLS) was used to screen out modeling wave band to establish partial least-squares models. The relative error method was applied to predict forecast set samples of Scutellariae Radix in three extraction phases. The results showed that the model established by Savitzky-Golay smoothing with 11 points (SG11 points) was the best, with the root mean square with cross validation (RMSECV), root mean square error of correction (RMSEC) and root mean square error of prediction (RMSEP) of baicalin of 0.092 7, 0.134 4 and 0.114 8, respectively, the determination coefficient R2 of greater than 0.99, and the relative error of baicalin content of less than 5%. This indicates that the on-line near infrared reflectance spectroscopy could be applied in on-line monitor and quality control of the extraction process of Scutellariae Radix formula particles.

Objective To investigate the association between (beta-parvin) PARVB gene rs5764455 polymorphism and susceptibility to non-alcoholic fatty liver disease (NAFLD). Methods A total of 230 patients with NAFLD (NAFLD, n = 230) and 230 control subjects (control, n = 330) were genotyped by PCR and direct sequencing. Clinical information was detected and compared in different groups. Genotypic frequency and gene frequency distribution in the two groups and relative risks to NAFLD susceptibility were assessed statistically , respectively. Results No statistical differences were observed between PARVB gene rs5764455 genotypic frequency with gene frequency distribution and the two groups, respectively (Genotypic frequency χ2 = 0.182, P = 0.913; gene frequency χ2 = 0.180, P = 0.672). Comparing C/T + T/T genotype carrier with C/C genotype carrier, there were no differences concerning the relative risks to NAFLD susceptibility (OR = 1.266, P =0.178;adjusted OR =1.631, P =0.096) before and after adjusting body mass, BMI and so on. In the latter group, there are significant differences in the increases of body mass, BMI, TG, ALT and AST (P < 0.05). Conclusion Non-relationship was observed between PARVB gene rs5764455 polymorphism and the risk of NAFLD in Qingdao Han Chinese.
