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.

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 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.

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.

Nine compounds were isolated from the n-butanol fraction of 95% ethanol extract of the fruit of Alpinia oxyphylla Miq. with a combination of various chromatographic approaches, including MDS resin, silica gel, reverse phase C18 and preparative HPLC. On the basis of spectroscopic data analysis, they were elucidated as (1R, 4R, 10R)-1β, 4α-dihydroxy-11, 12, 13-trinor-5, 6-eudesmen-7-one (1), 1β, 4β-dihydroxy-11, 12, 13-trinor-8, 9-eudesmen-7-one (2), oxyphyllenone A (3), oxyphyllenone B (4), rhamnocitrin (5), staphylionoside D (6), benzyl-1-O-β-D-glucopyranoside (7), 2-O-β-D-glucopyranosyl-(1S)-phenylethylene glycol (8), and (S)-1-phenylethyl-β-D-glucopyranoside (9). Among them, compound 1 is a new sesquiterpene, named as oxyphyllenone C; compounds 8 and 9 are new natural products; compounds 2 and 6 were isolated from the genus Alpinia for the first time, and compound 7 was isolated from A. oxyphylla for the first time.

Over the past three decades, more and more antisense drugs have been approved for marketing or clinical trails. Antisense technology has become the focus of pharmaceutical research due to its unique advantages in treating diseases and strong clinical development potential. There is a big difference from traditional small molecule chemical drugs, and macromolecular protein biological drugs. Antisense drugs are a very independent drug form. Antisense drugs were initially used to treat diseases with single gene mutations, but recently they have gradually begun to be used for the treatment of common diseases. Rational antisense drug design is crucial for disease treatment based on genetics. This paper reviews the latest progress in the field of action mechanism, chemical modification and delivery strategy of antisense drugs, and analyzes the current intractable problems. It is believed that with the resolution of these problems, the research of antisense drugs can reach a new level.

Linezolid is the first oxazolidinone antibacterial drug approved by the FDA, which can effectively treat various gram-positive bacterial infections, including blood infections, skin and soft tissue infections, community and hospital-acquired pneumonia. It has become one of the most commonly used antibiotics in clinical. In addition to the recently launched tedizolid phosphate (TR701) and contezolid (MRX-I), several oxazolidinone anti-infective candidates are currently under clinical research. This review briefly introduces the oxazolidinone antibiotics that have been marketed and are in clinical trials, and recent progress on the structure optimization of oxazolidinone drugs is also summarized.
