Objective To explore the feasibility, safety and effectiveness of mobile intensive care and pre-hospital surgical service for patients with severe thoracic injuries so as to further improve success rate of treatment of severe thoracic trauma. Methods A retrospective study was done on the clinical data of 72 patients with severe thoracic injuries (AIS≥3) treated by surgeons from Chongqing Emergency Medical Center (CEMC) from April 1998 to August 2008. The patients were divided into pre-hospital group (n = 36) and in-hospital group (n = 36) according to the time that the definite surgery performed. Results (1) There was no significant statistical difference upon arrival time from scene to primary hospital between two groups (P > 0.05). For patients in pre-hospital group, the time to receive definite surgery was (3.9±4.1) hours, which was significant shorter than (9.6±8.2) hours in in-hospital group (P < 0.05). (2) There were no statistical significant differences upon blood loss volume and blood transfusion volume between two groups (P > 0.05). (3) There was no significant statistical difference upon ISS value between two groups (P > 0.05), but the RTS value of pre-hospital group was significantly lower than that of in-hospital group (P < 0.05). The incidence rate of shock in pre-hospital group was 86.1%, which was significantly higher than 41.7% in in-hospital group (P < 0.05). (4) The percentage of patients who received thoracic close drainage in pre-hospital group was 16.7%, which was significantly higher than 5.6% in in-hospital group. There was no significant statistical difference upon thoracic close drainage plus thoracotomy, thoracic close drainage plus laparotomy and thoracic close drainage plus other operations between two groups. However, the operative rate of thoracic close drainage plus thoracotomy for penetrating injury was 4.8 times higher than that for blunt injury in pre-hospital group, and 1.9 times higher than that for blunt injury in-hospitai group. The operative rate of thoracic close drainage plus laparotomy for blunt injury was 5 times higher than that for penetrating injury in prehospital group, and 4.5 times higher than that for penetrating injury in in-hospital group. The overall survival rate was 95.8% (69/72). Five of eight moribund patients were saved in pre-hospital group, the prevented death rate accounted for 13.9% (5/36) in this group. Conclusions It is flexible, safe and effective to implement mobile intensive care and definite lifesaving surgical interventions for patients with severe thoracic injuries in primary hospitals. After the condition of the patient is stabilized, a quick transportation of the patients to a higher level trauma centers (hospitals) for further treatment may reduce the pre-hospital death rate.

OBJECTIVE To explore the influence of Zingiber officinale and processed Z. officinale on pharmacodynamic indexes and intestinal flora on gastric ulcer rats with spleen -stomach deficiency and cold type before and after processing with sand . METHODS The SD rats were randomly divided into normal group ,model group ,positive control group (Compound tianqi weitong capsule 0.45 g/kg),Z. officinale high-dose(15.0 g/kg)and low -dose(7.5 g/kg)groups,processed Z. officinale high- dose(15.0 g/kg)and low -dose(7.5 g/kg)groups,with 10 rats in each group . The rat model of gastric ulcer with spleen -stomach deficiency and cold type was established by intragastric administration of vinegar (day 1-10)and absolute ethanol (day 11). Administration groups were given relevant liquid intragastrically ,and normal group and model group were given water intragastrically(day 5-10). One hour after intragastric administration of absolute ethanol ,blood was taken from the femoral artery of rats ,the serum contents of motilin (MTL),gastrin(GAS),epidermal growth factor (EGF)as well as 4 items of blood coagulation [activated partial thromboplastin time (APTT),prothrombin time (PT),thrombin time (TT),fibrinogen(FIB)] were detect. The ulcer index and inhibition rate of ulcer in gastric tissue were calculated . The pathological changes of gastric tissue were observed,and the number and area of erosions were recorded . The diversity of gut microbiota in fecal samples of rats was detected . RESULTS Compared with model group ,the contents of MTL (except for processed Z. officinale low-dose group ),GAS(except for processed Z. officinale low-dose group ),EGF(except forofficinale groups) and FIB (except for Z. officinale groups),inhibitory rate of ulcer (only positive control group )were all increased significantly (P<0.05). APTT(except for Z. officinale groups),PT(only processed Z. officinale high- dose group ),TT(except for Z. officinale groups),ulcer index (except for Z. officinale groups),the number (except for Z. officinale groups)and area of erosions (except for Z. officinale groups)were shortened and decreased significantly (P<0.05); improvement effects of processed Z. officinale were better than those of the same dose of Z. officinale on EGF ,4 items of blood coagulation(except for PT ,TT,FIB of processed Z. officinale low-dose group ),ulcer index (except for processed Z. officinale low-dose group )and inhibitory rate of ulcer (P<0.05). Compared with model group ,α diversity indexes as ACE ,Shannon and Simpson of intestinal microorganisms in rats were increased significantly in processed Z. officinale group;the relative abundance of Proteobacteria was decreased significantly in processed Z. officinale group,while that of Bacteroidetes was increased significantly (P<0.05); the relative abundance of Limosilactobacillus was decreased significantly in Z. officinale group (P<0.05). CONCLUSIONS Z. officinale and processed Z. officinale can improve the symptoms of spleen -stomach deficiency and cold ,and enhance gastrointestinal function by increasing the content of GAS and MTL . Processed Z. officinale can significantly inhibit gastric ulcer of spleen -stomach deficiency and cold type ,which is related to the promotion of mucosal protection and repair ,improvement of coagulation functionand adjustment of gut microbiotadisorder .

ObjectiveTo investigate the key compounds affecting the irritation and to clarify the effect of heating and the addition of ginger juice as the auxiliary material during the processing on the irritation of Magnoliae Officinalis Cortex(MOC) by comparing the irritation and composition of volatile oil in MOC and its different processed products. MethodVolatile oil in raw products, water-processed products, ginger-dried products, ginger-fried products(the amounts of ginger were 10%, 50%, respectively) of MOC were extracted by steam distillation and subjected to rabbit eye irritation experiment, and the volatile components of each sample were detected by gas chromatography-mass spectrometry(GC-MS). Principal component analysis(PCA)and orthogonal partial least squares-discriminant analysis(OPLS-DA) were used to analyze the data of each sample by SIMCA 14.1. The relative contents of different processed products were compared two by two with those of and raw products or ginger-fried products, and the markers that might be related to the irritation were sorted out according to the principles of variable importance in the projection(VIP) value >1 and P<0.05, and the factors influencing the differences in irritation were analyzed. ResultCompared with the blank group, the administration groups all had irritation to the eyes of rabbits, and the degree of irritation was in the order of raw products>water-processed products>ginger-dried products>ginger-fried products(10%)>ginger-fried products(50%). The results of PCA and OPLS-DA showed that there were differences in the volatile oil from raw products and different processed products. According to VIP value>1 and P<0.05, and combined with the results of eye irritation experiment, ten volatile compounds related to irritation changes were screened out. Among them, cis-cinnamaldehyde was only detected in raw products, the relative contents of β-caryophyllene, (+)-delta-cadinene, α-humulene, γ-muurolene, (-)-isoledene and citral all increased to different degrees, the contents of p-cymene, 1(10)-4-cadinadien-15-ol and β-eudesmol all decreased to different degrees. ConclusionThe irritation of MOC is reduced after heating and processing with ginger juice, and the synergistic effect of both is more effective for reducing irritation. Among the differential markers associated with changes in irritation, the increase in the relative content of citral is closely related to the addition of ginger juice, while the decrease in the relative contents of cis-cinnamaldehyde, p-cymene, 1(10)-4-cadinadien-15-ol is related to heating, and the changes of other components may be related to the synergistic effect of heating and ginger juice.
