Purpose To explore the forensic pathological features of deaths caused by craniocerebral injury in traf-fic accidents,in order to provide forensic practitioners with a more rigorous approach to identification.Methods A retrospective analysis was performed on 225 autopsy reports of traffic accident fatalities resulting from craniocerebral in-jury.The causes of death were classified,tabulated,and analyzed.Results Among the 225 autopsy reports,the main causes of death included primary brain injury,secondary brainstem injury,and complications.The main types of injuries craniocerebral injuries observed were skull fractures,cerebral hemorrhage,cerebral contusion,cerebral edema and so on.Conclusion The occurrence of craniocerebral injury is related to factors such as age,vehicle,collision speed,and road conditions,and there is an inherent regularity to these factors.Forensic practitioners should combine comprehesive and systematic pathological examinations,clinical data,and the inherent regularities of related factors to make objective,comprehensive,and accurate determinations of the cause of death in traffic accident-related craniocere-bral injuries.

Objective To evaluate the accuracy of different biomarkers for early diagnosis of acute kidney injury ( AKI ) in the patients undergoing cardiovascular surgery under cardiopulmonary bypass ( CPB) . Methods A total of 200 patients, aged 22-86 yr, weighing 46-87 kg, scheduled for elective cardiovascular surgery under CPB, were enrolled in this study. The concentration of serum creatinine was determined at 1 day before operation and 1-7 days after operation. At 1 day before operation and 0, 2, 6 and 12 h after operation, the concentrations of urine neutrophil gelatinase-associated lipocalin (NGAL), cystatin C ( Cys C) , tissue inhibitor of matrix metalloproteinase type 2 ( TIMP-2) and insulin-like growth factor binding protein-7 ( IGFBP-7) were determined. The TIMP-2 and IGFBP-7 product ( TI) was calcu-lated. AKI was diagnosed after surgery according to Kidney Disease Improving Global Outcomes criteria. The receiver operating characteristic curve was plotted, and the area under receiver operating characteristic curve ( AUC) was calculated. Results The incidence of AKI was 20. 5％. The AUC of AKI diagnosed by the concentration of urine NGAL was 0. 689, 0. 709, 0. 713 and 0. 803 at 0, 2, 6 and 12 h after opera-tion, respectively ( P<0. 05) . The AUC of AKI diagnosed by the concentration of urine Cys C was 0. 639, 0. 762, 0. 774 and 0. 812 at 0, 2, 6 and 12 h after operation, respectively ( P<0. 05) . The AUC of AKIdiagnosed by TI was 0. 687, 0. 721, 0. 740 and 0. 779 at 0, 2, 6 and 12 h after operation, respectively ( P<0. 05) . The AUC of AKI diagnosed by combined three indices the parallel test was 0. 694, 0. 773 and 0. 794 at 0, 2 and 6 h after operation, respectively ( P<0. 05) . The AUC of AKI diagnosed by the serial test was 0. 610, 0. 631 and 0. 667 at 0, 2 and 6 h after operation, respectively. Conclusion Urine NGAL or Cys C concentrations or TI single detection and parallel test have a certain accuracy for early diag-nosis of AKI in the patients undergoing cardiovascular surgery under CPB.

Objective To establish biological detection method for Fuzheng Xiaoji capsule.MethodsTaken Radix astragali,Hedyotis diffusa Willd, Fructus Polygoni orientalis and rhubarb in Fuzheng Xiaoji capsule as targets, the antimicrobial activity of the single fried mixture of Radix astragali,Hedyotis diffusa Willd,Fructus Polygoni orientalis and rhubarb to 4 kinds of standard strains(Staphylococcus aureus, Salmonella, Escherichia coli and Bacillus subtilis) were inspected.The standard curve by susceptible strains of the inhibition zone diameter and logarithm of the concentration was established,and this test also determined the biological potency of different batches of Fuzheng Xiaoji capsule according to the dose-response curve.ResultsThe single fried mixture of Radix astragali,Hedyotis diffusa Willd, Fructus Polygoni orientalis and rhubarb have strong anti-bacterial effect to the above four standard strains.There was a good linear relationship between logarithmic dose and response effect when the concentration in the range of 0.029-0.136g/mL(r=0.9583).ConclusionBiological potency detection method can be combined with traditional analysis methods to control the quality of Fuzheng Xiaoji capsule.

Objective:To evaluate the effectiveness of abdominal acupuncture plus the Confluent Points of the Eight Extraordinary Meridian in treating chronic pharyngitis. Methods:Thirty eligible subjects with chronic pharyngitis were given abdominal acupuncture plus needling Lieque (LU 7) and Zhaohai (KI 6), two out of the Confluent Points of the Eight Extraordinary Meridian, once a day, 10 sessions as a course, and the therapeutic efficacy was evaluated after a treatment course. Results:After a treatment course, of the 30 subjects, 21 were recovered, 5 showed markedly effective, 2 were improved, and 2 failed,the total effective rate was 93.3%. Conclusion:Abdominal acupuncture plus the Confluent Points of the Eight Extraordinary Meridian is effective in treating chronic pharyngitis, worth promoting in clinic.
