Compared the quality of life between the two groups by interviewed questionnair. Results After the nursing intervention, the indexes which can indicated the quality of life in the intervention group were bettez than those of in the control group significantly. Conclusions Psychological nursing intervention can ef-fective promote the quality of life of patients with ovary cancer.

OBJECTIVETo explore the function of vascular endothelial cell (VEC) in patients with coronary heart disease (CHD) of Xin-blood-stasis syndrome.

METHODSSome vasoactive substances produced by VEC were detected and analyzed in patients with CHD of or without Xin blood stasis syndrome in group A (n=112) and group B (n=108) respectively, also in patients with non-CHD but of Xin-blood-stasis syndrome in group C (n=110), and healthy persons in group D (n=100), including nitric oxide (NO), endothelin (ET), angiotensin H (Ag II), soluble intercellular adhesion molecule-1 (sICAM-1) and soluble vascular cell adhesion molecule -1 (sVCAM-1).

RESULTSThe abnormality degree of ET, Ag II , sICAM-1 and sVCAM-1 in various groups showed such a tendency as group A> group B> group D (P < 0.01 or P < 0.05), while no significant difference in these criteria between group A and group C was shown (P > 0.05).

CONCLUSIONThe vasoactive substances secreted by VEC are closely related to the formation and progression of CHD, and are likely to be important pathological markers of blood-stasis syndrome in CHD.

Objective To study the changes of serum level of high mobility group box-1(HMGB- 1)in patients with multiple trauma in order to forecast organ dysfunction(OD)and deaths.Methods The optical densities of HMGB-1 in serum of 35 patients with multiple trauma were determined on 1st,3rd, and 7th days after trauma,and the incidence of organ dysfunction and deaths were evaluated,then analyzed statistically to learn the relation between the serum levels of HMGB-1 and deaths with an attempt of predic- ting the incident of organ dysfunction and deaths.Results (1)As OD was concerned,there was a statis- tically significant difference in optical density of HMGB-1 on 1st and 3rd days between the two groups of multiple injury patients(t=4.411,P

20(Z= -2.117, P=0.034), and between the patients with OD and without OD (Z=-3.089, P=0.002), but PCT was not so between the non-surviror and survivor (Z=-1.307, P=0.191). The serum PCT level correlated with the incidence of organ dysfunction (x~2=14.82, P=0.033) and APACHEII (x~2=12.83, P

OBJECTIVETo establish a microemulsion liquid chromatography system with direct sample loading for determining the serum level of emodin in rats.

METHODSThe separation was performed on C₁₈ column (Hypersil BDS, 5 µm,150 mm×4.6 mm) with the microemulsion mobile phase consisting of 3.3% (w/V) SDS, 6.6% (V/V) n-butyl alcohol, and 1.0% (V/V) octane and water. The flow rate was 1.0 ml/min and the detection wavelength was 254 nm.

RESULTSThe linear range of emodin detection was 0.333-5.32 µg/ml. The average recovery was 99.65% with a RSD of 3.60%. The limit of quantification was 0.1386 µg/mL.

CONCLUSIONMicroemulsion liquid chromatography system with direct sample loading allows simple, accurate and rapid determination of emodin in rat serum.

OBJECTIVETo explore the relationship between disseminated intravascular coagulation (DIC) and levels of plasma thrombinogen segment 1+2 (F1+2), D-dimer (D-D), and thrombomodulin (TM) in patients with severe multiple injuries.

METHODSIn this study, 66 patients (49 males and 17 females, aged 15-74 years, mean=38.4 years) with multiple injuries, who were admitted to our hospital within 24 hours after injury with no personal or family history of hematopathy or coagulopathy, were divided into a minor injury group (ISS<16, n=21) and a major injury group (ISS>or=16, n=45) according to the injury severity. The patients in the major injury group were divided into a subgroup complicated with DIC (DIC subgroup, n=12) and a subgroup complicated with no DIC (non-DIC subgroup, n=33). Ten healthy people (7 males and 3 females, aged 22-61 years, mean=36.5 years+/-9.0 years), who received somatoscopy and diagnosed as healthy, served as the control group. Venous blood samples were collected once in the control group and 1, 3 and 7 days after trauma in the injury groups. The F1+2 and TM concentrations were determined by enzyme linked immunosorbent assay (ELISA), and D-D concentrations were measured by automated latex enhanced immunoassay.

RESULTSF1+2, D-D and TM levels were higher in the minor and major injury groups than in the control group. They were markedly higher in the major injury group than in the minor injury group. In the non-DIC subgroup, F1+2 levels declined gradually while D-D and TM levels declined continuously. In the DIC subgroup, F1+2 and D-D levels remained elevated while TM levels exhibited an early rise and subsequent decrease. Plasma F1+2, D-D and TM levels were higher in the DIC patients than in the non-DIC patients. Injury-induced increases in F1+2, D-D and TM plasma levels had significant positive correlation with each other at each time point.

CONCLUSIONSBesides being related to trauma severity, F1+2, D-D and TM levels correlate closely with the occurrence of posttraumatic DIC. Therefore, changes in plasma F1+2, D-D and TM levels may predict the occurrence of DIC.

OBJECTIVETo investigate the application of damage control surgery in treatment of patients with severe thoracic and abdominal injuries.

METHODSA retrospective study was done on 37 patients with severe thoracic and abdominal injuries who underwent damage control surgery from January 2000 to October 2006 in our department. There were 8 cases of polytrauma (with thoracic injury most commonly seen), 21 of polytrauma (with abdominal injury most commonly seen) and 8 of single abdominal trauma. Main organ damage included smashed hepatic injuries in 17 cases, posterior hepatic veins injuries in 8,pancreaticoduodenal injuries in 7, epidural or subdural hemorrhage in 4, contusion and laceration of brain in 5, severe lung and bronchus injuries in 4, pelvis and one smashed lower limb wound in 3 and pelvic fractures and retroperitoneal hemorrhage in 6. Injury severity score (ISS) was 28-45 scores (38.4 scores on average), abbreviated injury scale (AIS) > or = 4.13. The patients underwent arteriography and arterial embolization including arteria hepatica embolization in 4 patients, arteria renalis embolization in 2 and pelvic arteria retroperitoneal embolization in 7. Once abbreviated operation finished, the patients were sent to ICU for resuscitation. Twenty-four cases underwent definitive operation within 48 hours after initial operation, 5 underwent definitive operation within 72 hours after initial operation, 2 cases underwent definitive operation postponed to 96 hours after initial operation for secondary operation to control bleeding because of abdominal cavity hemorrhea. Two cases underwent urgent laparotomy and decompression because of abdominal compartment syndrome and 2 cases underwent secondary operation because of intestinal fistulae (1 case of small intestinal fistula and 1 colon fistula) and gangrene of gallbladder.

RESULTSA total of 28 patients survived, with a survival rate of 75.68%, and 9 died (4 died within 24 hours and 5 died 3-9 days after injury). The trauma deaths at the early stage were caused by severe primary injuries resulting in failure of respiration and circulation, while mortality at the later stage was caused by multiple organ failure.

CONCLUSIONSDamage control surgery is important for the treatment against severe thoracic and abdominal injuries. It is suggested that the surgeon should select the reasonable auxiliary examination before operation, and take the proper time to perform damage control and definitive surgery.

The purpose of this investigation is to improve ethanol production and decrease acetate formation in Saccharomyces cerevisiae strain YS2-?adh2.The strain YS2-?adh2 with deleted alcohol dehydrogenase Ⅱ(adh2) gene was isolated in our lab with higher ethanol production than that of the strain YS2.The ace-taldehyde dehydrogenase Ⅵ(ald6) gene encoded a cytosolic acetaldehyde dehydrogenase,a key enzyme of the pyruvate dehydrogenase(PDH) bypass,transfers acetaldehyde to acetate.To disrupt ald6 gene of the strain YS2-?adh2,ald6 gene targeting cassettes were synthesized by long flanking homology PCR(LFH-PCR) and then were transformed into YS2-?adh2 mutants by LiAc/SS Carrier DNA/PEG method.Positive transformants were selected with G418 and further confirmed by PCR.Once correctly integrated into the genome,the selective marker was rescued by transforming the plasmid pSH65 into the positive transformants and inducing the Cre expression with a Cre/loxP-mediated marker removal procedure.We named the ald6 gene knocked-out strain as YS2-?adh2-?ald6 which has a 12.5% higher ethanol production and a 18% lower acetate formation compared to the strain YS2.

Objective　To establish animal model for hypertrophic scar and study the characters of its morphology and collagen metabolism. Methods　A total of 64 round wounds (diameter of 6 mm each) with total skin loss were made on the ventral side of rabbit ear using a trephine. Morphology and collagen metabolism of scar wounds were studied at 14,21,35,70 and 98 days after operation, respectively. Results　There were 76% elevated scars developed (45/59 wounds) on the ventral side of rabbit ear at 21 days and 46% elevated scars disappeared (11/24) at 98 days after operation. There were numerous fibroblast proliferation and whorl-arranged collagen fibers at 21 and 35 days. The number of fibroblast decreased, but irregular-arranged fibers still presented in the elevated scars at 70 and 98 days after operation. Hydroxyproline content in elevated scars at 21 days was higher than that in normal skin (P<0.05), and at 35 days was 3 times as that in normal skin and at 98 days was also markedly higher than that in normal skin (P<0.05). Conclusion　Excessive deposition of collagen is a characteristic of hypertrophic scar in rabbits. The conversion of normal scarring to hypertrophic scarring in rabbits occurs at 14～21 days after operation. Both development and regression of hypertrophic scar in rabbit are quicker than that in human.
