Objective To study effects of fluid resuscitation on thoracoabdominal injury combined with hemorrhagic traumatic shock.Method A total of 98 patients,who were treated in Affiliated Zhongshan Hospital of Dalian University from November 2004 to December 2006,were retrospectively analyzed.The patients were diagnozed according to Surgery(fifth edition).Patients were divided into delayed fluid resuscitation group(n= 51)and immediate fluid resuscitation group(n=47).Patients in delayed fluid resuscitation group were given with balanced salt solution for the body to maintain basic requirements.Patients in immediate fluid resuscitation group were rapidly administered with a lot of isotonic crystaUoid and(or)colloid solution after admission. Hemoglobin,platelet count,hematocrit,blood lactic acid,basedeficit,preoperative resuscitation time and mortality were compared between the two groups.Paired t test and variance analysis or x~2 test were used.Results The transfusion fluid volume of delayed group and immediate group was(1586?346)ml,(3520?575)ml, respectively,with P value

Pharmaceutical market is a typical market with information asymmetry, and which can lead to "lemons" problem. In all developed countries, firms must receive regulatory approval to market a pharmaceutical product. Such administrative department including SFDA, EMA, FDA and so on. Chinese materia medica is a special part of pharmaceutical market in China. The management of Chinese materia medica is a special challenge in China.

AIM: To investigate the effects of in situ transplantation of mobilized autologous bone marrow stem cells on infarction size and cardiac function in patients with acute myocardial infarction. METHODS:25 patients with first acute myocardial infarction were randomly divided into stem cells in situ transplantation group and control group, 12 patients in stem cells in situ transplantation group were injected subcutaneously with 300 ?g granulocyte colony-stimulating factor(G-CSF) daily for four days in addition to standard therapy. 13 patients in control group were treated with standard therapy alone. The conventional 12 leads electrocardiogram were recorded on 1, 28 days after admission and the cardiac function was scored by the QRS scoring system proposed by Wagner. Furthermore, the infarction size was assessed by radionuclide myocardial perfusion imaging 7, 28 days after admission. RESULTS:4 weeks after admission, the QRS scores decreased, the infarction size reduced significantly in the stem cells in situ transplantation group (from 36.0%?8.3% to 18.0%?5.8%, P

More than one hundred strains of marine molds have been isolated from the sediment and the sample of seawater collected from the South China Sea. By the first screening, more than 30 strains of marine molds which can inhibit tested fungi such as Candida albicans and Fursarium sp. were obtained.The results of the second screening showed those strains designed as B 4#-6、B 4#-3、1-B 6-6、1-B 6-10-5、1-B 6-22、C 2#-5、A 2-9 and 1-B 6-10 can produced extracelluar antifungi metabolic products and the crude extract of the strains 1-B 6-10-5 and B 4#-3 can inhibit the growth of many other species of fungi.

The effects of Cinnamon granules on pharmacokinetics of berberine in Rhizoma Coptidis granules in healthy male volunteers, and the compatibility mechanism of Jiao-Tai-Wan (JTW) composed of Rhizoma Coptidis granules and Cinnamon granules were investigated. The concentration of berberine in plasma of healthy male volunteers was determined directly by high performance liquid chromatography (HPLC) after an oral administration of Rhizoma Coptidis granules alone or combined with Cinnamon granules (JTW). The plasma concentration-time curves of berberine were plotted. The data were analyzed with Drug and Statistics (DAS) 2.0 pharmacokinetic program (Chinese Pharmacology Society) to obtain the main pharmacokinetic parameters. The results showed that the plasma concentration-time curve of berberine was described by a two-compartment model. The C(max), T(max), t(1/2) and CLz/F of berberine in Rhizoma Coptidis granules were 360.883 μg/L, 2.0 h, 3.882 h, 119.320 L·h(-1)·kg(-1) respectively, and those of berberine in JTW were 396.124 μg/L, 1.5 h, 4.727 h, 57.709 L·h(-1)·kg(-1) respectively. It was suggested that Rhizoma Coptidis granules combined with Cinnamon granules could increase the plasma concentration of berberine, promote berberine absorption and lengthen the detention time of berberine in healthy male volunteers.

OBJECTIVETo evaluate the erectile and ejaculatory function of sacral tumor patients after sacral nerve root resection and investigate the relationship of erectile and ejaculatory dysfunction (EED) with the level of sacral nerve injury.

METHODSThis retrospective study included 47 male patients aged 16 to 63 (32.6 +/- 6.8) years treated by sacral tumor resection between January 2008 and August 2013. According to the levels of the sacral nerve roots spared in surgery, the patients were divided into four groups: bilateral S1-S3 (n=16), unilateral S1-S3 (n=21), unilateral S1-S2 (n=6), and unilateral S1 (n=4). The patients were followed up for 12 to 41 (27.2 +/- 10.9) months by questionnaire investigation, clinic review, and telephone calls about their erectile and ejaculatory function at 3, 6 and 12 months after surgery and in August 2013.

RESULTSIn the bilateral S1-S3 group, the incidence rates of EED were 31.25% (5/16), 25% (4/16), and 12.5% (2/16) at 3, 6, and 12 months respectively after surgery, with recovery of erectile and ejaculatory function in August 2013. The incidence rates of EED in the unilateral S1-S3 group were 85.71% (18/21), 71.43% (15/21), 52.38% (11/21), and 42.86% (9/21) at 3, 6 and 12 months and in August 2013, respectively; those in the unilateral S1-S2 group were 100% (6/6), 83.33% (5/6), 83.33% (5/6), and 66.67% (4/6) at the four time points; and those in the unilateral S1 group were all 100% (4/4). No statistically significant differences were found in the incidence rate of EED among the patients of different ages or tumor types (P > 0.05).

CONCLUSIONThe incidence of postoperative EED in male patients treated by sacral tumor resection is closely related to the mode of operation. Sparing the S3 nerve root at least unilaterally in sacral tumor resection is essential for protecting the erectile and ejaculatory function of the patient.

Objective To investigate the expression of Toll-like receptor 3 (TLR3) on dendritic cells(DCs) derived from peripheral blood mononuclear cells(PBMCs) of chronic hepatitis B(CHB) patients and to explore the mechanism of sustained infection of hepatitis B virus (HBV). Methods Twenty CHB patients were randomly screened in the study,and ten healthy persons were recruited as controls.The monocytes isolated from peripheral blood of candidates were incubated with recombinant human granuloeyte macrophage colony-stimulating factor (rhGM-CSF) and rhIL-4 to induce the DCs generation and proliferation.Then the phenotype of DCs was identified by micro- scope.The expressions of the phenotypes[histocompatibility leukocyte antigen(HLA)-DR,CD80, CD86,CD83]of immature and mature DCs were measured by flow cytometer.Furthermore,the ex- pression of TLR3 on mature DCs(mDC) and immature DCs(imDC) was determined by flow cytometry and Western blot analysis respectively.Results As for healthy volunteers,the expressions of CD80, CD86,HLA-DR and CD83 on DCs at the 7th day,which were(82.35?8.67)%,(79.61?10.08)%, (92.79?8.48)% and (83.76?5.47)% respectively,were significantly higher than those at the 5th day which were(28.31?8.79) %,(31.17?11.23)%,(27.61?10.28)% and (23.46?11.53)% respec- tively(P0.05).The expression of TLR3 on imDC was significantly higher than that on mDC at control group (P0.05).And the expression of TLR3 on imDC in CHB patients group was significantly lower than that of control group(P
