The effects of thyrotrophin releasing hormone(TRH) given 0.5h after injury on survival and ?-endorphin release in scalded rats (about 30% TBSA, 20s in 100℃ water) were studied. The results showed tenfold increase of ?-endorphin-like immunoreactivity (ir-?-EP) in the plasma and the pituitary 2h after scald, while in the hypothalamus ir-?-EP did not rise above control until 6h after scald. 24h after scald, survival in rats given TRH was 46.7% and those given saline was 6.7% (P

The effects of hemorrhagic shock on the platelet functions in non-heparinized rabbits were studied. It was found that the platelet adhesiveness and aggregation and the pasma level of serum serotonin and throraboxane B2 significantly increased in the early period of hemorrhagic shock. Thereafter, as the shock was progressing, the platelet adhesiveness and aggregation were gradually inhibited while plasma level of serotonin and thromboxane B2 increased further and reached the peak in the 3rd hour after the onset of shock.The results indicated that the release of vasoactive substances such as serotonin and thromboxane after the activation of platelets seems to play a more important role than platelet adhesion and aggregation in the pathogenesis of hemorrhagic shock.

Nicotinic acetylcholine receptors(nAChRs) construct a family of ligand-gated ion channels. nAChRs distribute extensively in central nerve system, neuromuscular junctions and surface of other cells. The differences on subunits and tissue location determinate the diversity of receptor functions. Early research has found that nerve signal transmission is its main function and recent research found it also the key receptor of cholinergic anti-inflammatory pathway. To illuminate the physiological mechanism of these functions has great clinical significance for the treatment of correlated diseases such as myasthenia gravis, epilepsy and multiple organ failure.

Objective To compare the effect of enteral administration and intravenous infusion of hypertonic electrolyte glucose solution (HEGS) in the resuscitation of burn shock. Methods Fifteen beagle dogs with 35% TBSA third degree burn were used in present study, and divided into three groups randomly: noresuscitation group, intravenous infusion resuscitation group and enteral administration resuscitation group. For the animals in the latter two groups, 1.8% HEGS was administrated intravenously or enterally for resuscitation 30 min after burn. The volume of fluid infusion in the first 8h was 1ml/(kg?1% TBSA), and the transfusion velocity was equilibrated. The mean arterial pressure (MAP), cardiac index (CI), plasma volume (PV), and sodium concentration in plasma were obtained to evaluate the effect of resuscitation used HEGS. Results The MAP, CI and PV were similar in both enteral and intravenous groups, which were higher than those in noresuscitation group. In both enteral and intravenous groups, MAP was raised after burn and then lowered after resuscitation, meanwhile CI and PV were raised and then lowered after resuscitation, but there were no differences between the two groups. The sodium concentration in plasma was stable in the noresuscitation group and increased in enteral and intravenous groups, and it was higher in intravenous groups than in enteral group. Conclusion In the resuscitation of early shock of 35% TBSA three degree burns, the effect of 1.8% HEGS administrated enterally on CI, PV, MAP and sodium concentration in plasma was similar to that of intravenous infused.

Objective:To explore yhe therapeutic effect of Shenfu injection on patients of hepatic cirrhosis with seroperitoneum(yang de ciency of spleen and kidey synndrome).Methods:The 84 patients were divided into treatment group and control group,the patients in treatment group were treated with western medicine and Shenfu injection,only western medicine were used in control group,they were all treated for twenty-eight days.Results:The curative e ect,extinction time of seroperitoneum,amelioration of hepatic function and blood routine of the treatment group were better than those of control group.And there were statistical signi canc between two groups(P

Objective To observe the effects of carbachol(a cholinergic agent)on gastric emptying and gastric blood flow in resuscitation of early shock with oral administration of glucose-electrolyte solution(GES)in scalded rats.Methods Seventy-eight male Wistar rats were randomly assigned into five groups:shame scald(n=6),scald without fluid resuscitation(n=18),scald resuscitated with oral GES alone(n=18),scald resuscitated with oral carbachol alone(CAL,n=18),and scald resuscitated with oral carbachol plus GES(GES/CAL,n=18).About 35% TBSA scalded injury on back of rats was produced with boiling water(100℃,15s)in the latter four groups.GES(2ml/kg,which is equivalent to half volume of fluid infusion in first 24 hour according to Parkland' formula)was given twice in two-hour intervals by gavage beginning from 30min after the injury in GES and GES/CAL group.Carbachol(60?g/kg)was gavaged 30min after the injury in CAL and GES/CAL group.The gastric emptying rate was determined by phenol red emptying method and gastric blood flow was measured with laser Doppler at 2h,4h and 6h after the scald injury.Results The gastric emptying was obviously delayed and gastric blood flow was significantly reduced in scald animals compared with those in sham group(P

Oral fluid resuscitation in early period of hypovolemic shock is an important measure in the treatment of casualties in the battlefield as well as in mass casualties in lieu of the means of establishing a venous line. The main tasks in the study of oral rehydration resuscitation are the proposition of appropriate prescriptions of the liquids to be given and methods of administration on the basis of a clear elucidation of the mechanism underlying the function of the digestive system in regard to transportation and absorption of the given ingredients. The aim of the study is to fully replenish maximal amount of fluid containing glucose and electrolytes in a convenient, expeditious, and effective way in a minimal span of time, in order to increase circulating blood volume. At the same time, ischemia and tolerance to oral fluids of the gastro-intestinal tract should be improved, electrolyte imbalance and incidence of secondary infection should be alleviated, and finally hypovolemic shock is corrected, so that the victim is kept alive and prepared for further definitive surgical intervention.

Methods:With extracting data from HIS and other systems, check and audit the inpatient expense, such as billing classification, red account records, logic checks, integrity checks, etc, according to pre-established rules. Results:Using the auditing software can greatly improve the work efficiency and the accuracy of inpatient expense, reduce the incidence of billing dispute issue. Conclusion:This system has valuable reference and be worth generalizing because it can bring the social benefit to hospital.

As a non-pungency inhaled agent with less respiratory irritation,sevoflurane has been widely used in various surgeries for induction and maintenance of general anesthesia.However,the incidence of pediatric emergence delirium has been significantly increased with sevoflurane general anesthesia which severely disturbs the surgical effect and increases the requirement of medical staff in post anesthesia care unit.This article systematically reviews the research advance in emergence delirium in children with sevoflurane general anesthesia and introduces the reasonable intervention for the improvement of anesthesia quality.

OBJECTIVETo explore the clinical effects of Dynesys system combined with posterior lumbar interbody fusion (PLIF) in treating multiple lumbar degenerative disease.

METHODSThe clinical data of 46 patients with multiple lumbar degenerative diseases treated by Dynesys system combined with PLIF from September 2010 to May 2013 were retrospectively analyzed. There were 17 males and 29 females, aged from 38 to 68 years old with an average of (56.38±11.63) years. Operation section was in L2-L5 of 16 patients (6 with fusion of L4,5 and 10 with fusion of L4,5,L5S1) and in L3-S1 of 30 patients (11 with fusion of L5S1 and 19 with fusion of L4,5,L5S1). Patients were followed up for three times: postoperative 3 months, 1 year and final follow-up. Visual analogue scale (VAS) and Oswestry Disability Index (ODI) were used to assess clinical symptoms preoperatively and postoperatively. All patients underwent flexion/extension radiographs examinations before surgery and at final follow-up. Range of motion (ROM) and disc height index (DHI) were recorded.

RESULTSAll patients were followed up from 16 to 48 months with the mean of (23.23±7.34) months. At third follow-up after operation, ODI and VAS of lumbago and leg pain were significant improved than that of preoperative (P<0.01). DHI of fusion segment was significantly increased than that of preoperative (P<0.05). There was no significant difference in adjacent non-fusion segment between preoperative and postoperative (P>0.05). Postoperative ROM of fusion and non-fusion segments were obviously decreased than that of preoperative. There was no significant difference in ROM of upper adjacent non-fusion segment between 3 months and 1 year after operation (P>0.05), but at final follow-up, the ROM was increased (P<0.05).

CONCLUSIONThe preliminary clinical results of the Dynesys system combined with PLIF in the treatment of multiple lumbar degenerative diseases are satisfactory. It can be determined in fusion or non-fusion according to the individual needs and can reserve the some intervertebral motion, prevent the early degeneration of adjacent segments. However, its long-term clinical efficacy should be verified with long time.
