Objective To evaluate the physiological variables,which precisely and reliably reflected the effect of emergency fluid therapy for severely traumatized patients, in order to set up the ultimate criteria of optimal goal in fluid resuscitation. Method A total of 149 patients with severe trauma were given fluid resuscitation and were stratified into 3 groups with different severities of trauma as per ISS (injury severity score) and APACHE Ⅱ . Of all patients, heart rate (HR), systolic blood pressure (SBP), oxygen saturation of arterial blood (SaO2), blood gas analysis, arterial blood lactate (ABL), oxygen saturation of central venous blood (SCVO2) or oxygen saturation of mixed venous blood (SVC2), urine output, base excess (BE) and oxygenation index (OI = PaO2/FiO2) were measured and calculated. These variables were compared between groups to find out the significant differences and the relationship to response time to fluid therapy as well as complications and outcomes. Results Within 24 hours of fluid resuscitation, 127 patients reached the therapeutic goal in respect of systemic hemodynamics improved including the variables of SBP, HR and urine output, and the optimal goal of fluid therapy in 112 patients was estimated with cellular oxygen available found in the levels of ABL, BE and OI measured. These two sets of criteria (clinical signs vs laboratory findings) for determining the therapeutic goal showed significant difference in length of time taken for reaching the goal of treatment ( P < 0.05). There were significant differences in APACHE Ⅱ scores between those reaching the therapeutic goal within 24 hours and those taking longer time over 24 hours reaching the therapeutic goal or the death (P < 0.01). The duration of persistence in abnormal systemic hemody-namics and laboratory findings was longer in patients with complications or injured to death than that in survivors (P <0.05 -0.01). Conclusions In addition to the stability of vital signs, tissue perfusion and cellular oxy-genation should be taken as ultimate criteria of successful fluid resuscitation for severely traumatized patients judged by means of measuring the ABL, BE and OI variables.

Chinese Traditional and Herbal Drugs 2019;50(20):4884-4888
Objective: To explore the placebo-preparation method of Ginkgo Folium Dropping Pills (GFDP) and evaluate its simulation effect objectively, which could provide production and evaluation reference for Chinese materia medica (CMM) placebo. Methods: Taking the placebo-preparation of GFDP as an example, the simulation effect was evaluated from aspects of appearance, color, smell, and taste. It employed three different approaches as possibility of experimental drug, similarity evaluation between placebo and experimental drug and the similarity analysis among the drugs. Results: The two placebo-preparation prescriptions of GFDP have high similarity with the original drug in terms of appearance, color, smell, and taste. The simulation effect of No. 2 placebo-prescription (0.6 g of sucrose octaacetate as bitter agent, 2.1 g of caramel as colorant, 13.3 g of PVP K30 as fillerz and 44.0 g of PEG 4000 as water-soluble bases to prepare 1 000 pills) is better than No. 1 placebo-prescription (1.2 g of sucrose octaacetate as bitter agent, 2.1 g of caramel as colorant, 12.7 g of PVP K30 as filler, and 44.0 g of PEG 4000 as water-soluble bases to prepare 1 000 pills). Conclusion: The placebo-preparation of GFDP conform to placebo requirements of randomized controlled trials. It fills the vacancy of dropping pills form placebo-preparation in CMM and provides method and idea for placebo-preparation and simulation-effect evaluation of CMM.

Chinese Traditional and Herbal Drugs 2015;46(15):2265-2269
Objective: To explore the correlation between the high expression of hepcidin and vascular endothelial damage and the intervention effect of tetramethylpyrazine (TMP). Methods: Twenty-four SD rats were randomly divided into four groups: blank control, model, heparin, and TMP groups. Except the rats in the blank control group, the rats in all other groups were fed with high-fat diet for 8 weeks. The rats in the blank control and model groups were injected with normal saline at 2 mL/(kg∙d). The rats in the TMP group were injected with TMP at 40 mg/(kg∙d), and heparin at 5 mg/(kg∙d) was given to those in the heparin treated group. After rats were given medicine for 7 d, the levels of blood lipid, serum hepcidin, NO, ET-1, ROS, MDA, CAT, and SOD were detected. Results: As compared with blank control group, the levels of hepcidin, ET-1, ROS, and MDA in serum were significantly increased in the model group (P < 0.05), while NO, CAT, and SOD were obviously decreased (P < 0.05). Compared with the model group, the levels of hepcidin, ET-1, ROS, and MDA in serum were obviously decreased in TMP and heparin groups (P < 0.05), while NO and CAT were obviously increased (P < 0.05). Conclusion: Hepcidin expression is increased with the vascular endothelial damage aggravated. After rats are given TMP, the level of serum hepcidin and extent of vascular endothelial damage are decreased. It is suggested that TMP has the protective effects on the vascular endothelial function might be correlated to inhibiting high expression of hepcidin.

Though Runx2 and Osterix are both key transcription factors in the pathway of osteoblast differentiation, whether Runx2 positively regulates Osterix being unknown. It was showed that Runx2 induced the gene expression of Osterix both in the non-osteoblastic cell lines, either pluripotent or differentiated, and in the osteoblastic cell lines. At the same time, the results also indicated that Runx2 up-regulated the activity of the 3.2 kb human Osterix promoter. Further experiments identified a highly conserved and functional Runx2 binding site "AGTGGTT" within the promoter. Thus the results support the hypothesis that Runx2 is involved in the regulation of the Osterix gene expression. Moreover, the transient transfection and dual-luciferase assay showed Osterix up-regulated the activity of the 2.3 kb type Ⅰ collagen promoter in the non-osteoblastic cells, but Runx2 did not. This difference implies that Osterix, the down stream transcription factor of Runx2 during osteoblast differentiation, is needed to stimulate the osteoblast-specific gene expression of type Ⅰ collagen.

Objective To investigate the relationship between hemodynamic parameters from quantitative analysis of contrast-enhanced ultrasonography (CEUS) on hepatocellular carcinoma (HCC) and pathological tumor differentiated grades. Methods Seventy-seven HCC lesions were examinated and off-line analyzed with dynamic images. Quantitative parameters such as slope of decrease to half of peak (SD), increased signal intensity (ISI), area under the curve (AUC) and blood flow coefficient (BF) were acquired, and the standardized values (sISI, sAUC and sBF) included the ratio of parameters from tumor to those from hepatic parenchyma. These quantitative parameters were correlated with tumor grades according to Edmonson criteria. Results There was significant difference (P<0.05) of SD, AUC and BF, as well as standardized values (sISI, sAUC and sBF) between different grades of HCC. AUC, BF, sISI, sAUC and sBF were negative correlated with differentiated grades, respectively (P<0.05). Well-differentiated HCC had significantly higher perfusion values than HCC of other grades (P<0.05). Conclusion Quantitative analysis of CEUS can assess differentiation of HCC indirectly, and might reveal biological behavior of malignant tumors.
