Traumatic coagulopathy is a serious complication of tissue damage caused by trauma.In clinic,it easily develops into multiple system organ failure and results in high mortality.Traumatic coagulopathy is a plurality of blood coagulation disorder,its pathogenesis is extremely complex and involves tissue damage,blood coagulation,anticoagulation and fibrinolysis,inflammation and many other pathophysiological aspects.An in-depth study on the pathogenesis of traumatic coagulopathy is very important to improve clinical effect.This paper tries to do a review of recent study progress from pathophysiological mechanisms and hopes to provide reference for clinical work.

The growth inhibition and pro-apoptosis effects of dracorhodin perchlorate on human prostate cancer PC-3 cell line were examined. After administration of 10-80 μmol/L dracorhodin perchlorate for 12-48 h, cell viability of PC-3 cells was measured by MTT colorimetry. Cell proliferation ability was detected by colony formation assay. Cellular apoptosis was inspected by acridine orange-ethidium bromide fluorescent staining, Hoechst 33258 fluorescent staining, and flow cytometry (FCM) with annexin V-FITC/propidium iodide dual staining. The results showed that dracorhodin perchlorate inhibited the growth of PC-3 in a dose- and time-dependent manner. IC50 of dracorhodin perchlorate on PC-3 cells at 24 h was 40.18 μmol/L. Cell clone formation rate was decreased by 86% after treatment with 20 μmol/L of dracorhodin perchlorate. Some cells presented the characteristic apoptotic changes. The cellular apoptotic rates induced by 10-40 μmol/L dracorhodin perchlorate for 24 h were 8.43% to 47.71% respectively. It was concluded that dracorhodin perchlorate significantly inhibited the growth of PC-3 cells by suppressing proliferation and inducing apoptosis of the cells.

OBJECTIVETo verify the pharmacological hypothesis of prescriptions by studying the targeted distribution of major components in stewed rhubarb in the rat model with acute pancreatitis (AP).
METHODNormal SD rats (control group, n = 5) and the AP model induced with intraperitoneal cerulein (model group, n = 5) were taken as the experimental objects. Rats of the two groups were orally administered with stewed rhubarb granules (20 g x kg(-1)). Their heart, liver, spleen, lung, kidney and pancreas were collected two hours after the administration. Such constituents as emodin, chrysophanol, physcion, rhein and aloe-emodin and their concentrations in each tissue homogenate were detected by high performance liquid chromatography-mass-mass.
RESULTAloe-emodin and physcion in stewed rhubarb whose concentrations in liver and kidney of normal rats were higher than that in pancreatic tissues, while the distribution spectrums and concentrations of the remaining components in pancreatic tissues had no significant difference with that of other organs. The concentrations of emodin, aloe-emodin, rhein and chrysophanol in stewed rhubarb in pancreatic tissues of the AP model group were higher than that in other tissues and organs, while their concentrations in pancreatic, renal and splenic tissues were notably higher than that in the normal group.
CONCLUSIONIn the conditions of AP, effective components in stewed rhubarb show a targeted distribution feature in pancreas, which provides experimental basis for the pharmacological hypothesis of prescriptions.

Objective To systematically assess the efficacy and safety of non-indwelling urinary catheter during perioperative period of cesarean section.Methods The databases including Medline(PubMed),EMbase,Cochrane Library,CNKI and WanFang Data were retrieved by computer.The randomized controlled trials (RCTs) on the efficacy and safety of non-indwelling urinary catheter during perioperative period of cesarean section were comprehensively collected.Two reviewers independently screened literatures,extracted the data and assessed the quality.The Meta-analysis was conducted by using RevMan 5.3 software.Results A total of 5 RCTs involving 1 090 patients were included.The meta-analysis results showed that compared with the indwelling urinary catheter group,although the non-indwelling urinary catheter group increased the incidence rate of urinary retention[RR=11.67,95%CI(2.22,61.24),P<0.01],but significantly decreased the incidence rate of urinary tract infection(UTI) [RR=0.10,95%CI(0.04,0.26),P< 0.01] and incidence rate of initial urination discomfort [RR=0.17,95%CI (0.04,0.74),P=0.02],significantly shortened the initial time of off-bed activities [SMD=-3.68 ,95%CI(-5.25,-2.12),P<0.01]and hospitalization time [SMD=-1.03,95%CI(-1.67,-0.38),P<0.01].There were no significant differences in the operation time[SMD=-0.13,95%CI(-0.32,0.07),P=0.20] and incidence rate of postpartum hemorrhage (PPH)[RR=1.50,95%CI (0.43,5.26),P=0.53],The incidence rates of bladder injury in the two groups were similar.Conclusion According to the evidence of current clinical researches,selecting non-indwelling urinary catheter in elective cesarean section is effective and safe,prompting that indwelling urinary catheter during the perioperative period of cesarean section is selective rather than routine indwelling.

The essential medium of B115 composed of 1% tryptone, 0.25% yeast extract and 0.5% sodium chloride was determined by using an orthogonal design. The orthogonal design was also employed in testing the optimum additions. It was composed of 0.1%(NH_(4))_(2)SO_(4),1.4%K_(2)HPO_(4), 0.6% KH_(2)PO_(4) and 0.1% (Na_(3)C_(6)H_(5)O_(7)). The yield of B115 cultured in optimum medium was compared with the one in essential medium. Statistic analysis showed that the growth of B115 was most significantly improved by adding K~(+)、NH~+_(4) and (Na_(3)C_(6)H_(5)O_(7)) to essential medium. The antibacterial effect of Bacillus subtilis strain B115 on pathogenic Aeromonas was studied. The results showed different antibacterial effects of B115 on different aeromonads. There were obvious antibacterial effects on BSK-10 and CL990920, while no effect on the growth of TL970424.

Professor LI Zhi-dao's acupuncture technique at muscle belly and its clinical experiences for the treatment of arthralgia are introduced. From aspects of TCM, anatomical physiology and sports biomechanics, the theory basis of this technique is explained, while its method is elaborated in details from acupoint selection and manipulation combined with classic medical cases. The acupuncture technique at muscle belly is applied at the muscles which already have pathological changes, avoiding re-stimulation on the pain area. It provides new thinking methods and references for acupuncture to treat arthralgia.

ObjectiveTo establish a rat model of nerve damage induced by intrathecal(IT) lidocaine.MethodsFifty-five adult male SD rats weighing 200-220 g were randomly divided into 5 groups (n =11 each):group normal control (group C); group dimethyl sulfoxide (DMSO)-the solvent(group D) and groups IT 5%,10%,15% lidocaine (groups L5.10.15 ).IT catheter was successfully implanted without complication in groups D,L5,L1o,L15.DMSO,5%,10% and 15% lidocaine 20 μl were injected IT in groups D,L5,L10,L15 respectively.Motor dysfunction of hindlimb was assessed and scored (0 =normal,2 =complete block) and paw withdrawal threshold to mechanical stimulation (von Frey filaments) (MWT) and paw withdrawal latency to thermal nociceptive stimulus (TWL) were measured before (baseline) and at 1,2,3,4,5,7 d after IT administration in 8 animals in each group.Three animals in each group were sacrificed at 1 d after IT administration.The lumbar segment (L4-5) was removed for microscopic examination.ResultsThere was no significant difference in motor dysfunction score,MWT and TWL among groups C,D and L5.MWT was significantly increased and TWL prolonged at 1 and 2 d after IT administration in group L10,while in group L15 motor dysfunction score was significantly increased at 1,2 d after IT administration and MWT was significantly increased and TWL prolonged at 1,2,3 d after IT administration.There was significant histologic damage to spinal cord in groups L10 and L15.Conclusion Nerve damage can be induced by IT 10% lidocaine.
