Objective To analyze the effect of Shuxuetong injection on microcirculation in patients with septic shock and its therapeutic effect. Methods A prospective study was conducted. Eighty patients with septic shock treated in Department of Critical Care Medicine of Hebei Provincial Traditional Chinese Medical Hospital were randomly divided into a Shuxuetong group and a conventional therapy group according to random number table, 40 cases in each group. The conventional treatment in the two groups was energetically carried out in accord to the sepsis shock guidelines, such as positive fluid resuscitation, anti-infection, etc. In the Shuxuetong group, additionally Shuxuetong injection 6 mL in 5% glucose injection 250 mL intravenous drip was given once a day for 7 days. The levels of urine output, lactic acid (Lac), blood urea nitrogen (BUN), creatinine (Cr), aspartate aminotransferase (AST), alanine aminotransferase (ALT), left ventricular ejection fraction (LVEF), and cardiac index (CI) in the two groups were observed before and after treatment; the total dosages of dopamine, dobutamine, noradrenaline, etc. vascoactive agent used for the patients and 28-day mortality in the two groups were also recorded. Results The comparisons of levels of urine output, Lac, BUN, Cr, AST, ALT, LVEF, and CI before treatment between the two groups were of no statistical significant differences (all P>0.05). After treatment in the two groups, the urine output, LVEF, and CI were increased compared with those before treatment, whereas the Lac, BUN, Cr, AST, and ALT were significantly decreased, and the changes were more obvious in Shuxuetong group [urine output (mL/h):112.1±39.8 vs. 73.3±28.5, LVEF:0.49±0.15 vs. 0.44±0.14, CI (mL·s-1·m-2):66.2±5.7 vs. 54.2±6.2, Lac (mmol/L):3.83±1.65 vs. 4.72±2.25, BUN (mmol/L):7.1±2.7 vs. 9.3±3.5, Cr (μmol/L): 73.9±16.2 vs. 95.7±15.8, AST (U/L): 39.8±9.5 vs. 45.8±12.7, ALT (U/L):34.3±9.7 vs. 41.7±11.3, all P<0.05]. The total dosages of all kinds of vascoactive agent of Shuxuetong group were remarkably less than those in the conventional therapy group [dopamine (mg): 993.1±261.7 vs. 1 340.9±356.4, dobutamine (mg):776.2±281.0 vs. 1 049.2±364.3, noradrenaline (mg):56.4±34.6 vs. 107.6±51.3, all P<0.05]. The 28-day mortality of Shuxuetong group was obviously lower than that of conventional therapy group [40.0%(16/40) vs. 60.0%(24/40), P<0.05]. Conclusion Shuxuetong injection can improve the microcirculation perfusion in patients with septic shock and reduce their mortality.

Objective To explore effects of endoscopic subtotal thyroidectomy on nodular goiter and its clinical significance.Methods From Jun.2004 to Dec.2009,72 patients with nodular goiter underwent endoscopic subtotal thyroidectomy in Southwest Hospital.Of the 72 cases,22 cases had left-side nodule,31 cases had right-side nodule and 19 cases had bilateral nodules.Single thyroid nodule occurred in 41 cases and multiple nodules in 31 cases.The total number of nodules was 113.The average nodule size was 2.8 cm(ranging from 0.4 to 6.3 cm).Results Of the 72 cases,19 patients underwent bilateral subtotal thyroidectomy and the mean operative time was 97 min(ranging from 80 to 150 min).53 patients underwent unilateral subtotal thyroidectomy and the mean operative time was 65 min(ranging from 25 to 120 min).The mean intraoperative blood loss was 45 ml (ranging from 5 to 120 ml).Of the 72 cases,68 cases were given cervical plexus block regional anesthesia and among them 66 cases(97%)acquired good anesthesia.Temporary hoarse voice occurred in 2 cases and postoperative bleeding occurred in the subcutaneous tunnel of breast in 2 cases.Patients were followed up from 3 to 5years and the cosmetic result was satisfactory.The postoperative review half year later showed that unilateral nodule recurred in 1 case and the recurrence rate was 1.4%.Conclusions Endoscopic subtotal thyroidectomy through anterior chest wall or breast approach under local anesthesia is a safe and effective treatment in nodular goiter.In the process of dissecting thyroid,blunt maneuver and proper use of ultrasonic knife instead of clamping thyroid nodules directly are recommended in order to reduce intraoperative blood loss and enhance safe practice.

AIM To investigate the effect of fenofibrate and simvastatin on the serum free fatty acids of alcoholic fatty liver in rats. METHODS The rat model of alcoholic fatty liver was reproduced by chronic ethanol ingestion plus olive oil diet. The model rats were divided into three groups as follows: finofibrate treatment group(finofibrate 80 mg?kg -1 po, once a day),simvastatin treatment group (simvastatin 4 mg?kg -1 po, once a day)and control group without either above-mentioned treatment. Experimental rats were treated for four weeks and then sacrificed for blood sampling. Serum free fatty acids were analyzed by gas chromatography. RESULTS Fenofibrate significantly ameliorated the decrease in polyunsaturated fatty acids induced by ethanol [oleic acid:(38.212?7.788) ?g?L -1 vs (31.620?6.142) ?g?L -1,linoleic acid:(37.269?8.065) ?g?L -1 vs (30.254?9.063) ?g?L -1,arachidonic acid:(11.646?2.601) ?g?L -1 vs (9.012?1.236) ?g?L -1] accompanied by the improvement of the fat infiltration of the liver, but demonstrated no effect on the increase in serum saturated fatty acids by ethanol. In the contrast, simvastatin can aggravate the decrease in polyunsatrurated fatty acids and significantly increase the levels of satrurated fatty acids in serum induced by ethanol along with the pathological aggravation of alcoholic fatty liver. CONCLUSION The results of present study revealed that fenofibrate and simvastatin exerted different effect on the serum free fatty acids of alcoholic fatty liver. Polyunsatrurated fatty acids in the serum play an important role in the pathogenesis and treatment response of alcoholic fatty liver.

Objective To study the expression of KAI1 and CD40 in gastric cancer and their correlation with clinicopathologic features and prognosis.Methods The expression of KAI1 and CD40 of 64 gastric cancer tissues was examinated by S-P immunohistochemieal methods.Results The overall positive rate of KAI1 was 22% in gastric cancer.Expression of KAI1 was positively related to the degree of tumor differentiation,it was negatively related to invasion depth and lymph node metastasis and the tumor clinical stage.The 5-year survival rate of cases with positive expression of KAII was significantly higher than that of cases with negative expression(X~2=42.426,P=0.000).The expression rate of CD40 in gastric cancer tissue was 34%.The expression of CD40 was significantly correlated with metastasis and clinical stage of gastric cancer.The 5-year survival rate of cases with positive expression of CD40 was significantly lower than that of cases with negative expression(X~2=4.841,P=0.028).There is no relationship between KAI1 and CD40 expression in gastric cancer.Conclusion KAI1 is associated with gastric cancer differentiation,invasion and metastasis.CD40 status helps to evaluate metastasis,and predict prognosis of gastric cancer.

OBJECTIVETo understand the levels of total physical activities among different populations, and the distribution of four domains.

METHODSWith proportional stratified sampling and cluster sampling method, 3555 subjects were selected including officials, company staff, high school students, community population and floating population.

RESULTSThe proportions for inactive, insufficiently active, minimally active and health enhancing physical active (HEPA active) as a whole were 20.5%, 10.1%, 26.5% and 42.9% respectively. Community population had the highest level of HEPA active which was 65.6%. Floating population had the highest level of inactivity of 33.1%. Apart from the male floating population, the active level in transportation, physical activity among the investigated were the highest compared to other three active domains. Leisure-time physical activity was in the opposite.

CONCLUSIONThe type of physical activities among general citizens were mainly of physical activity related to transportation but less leisure-time physical activity was seen. Floating population had the highest level of both HEPA activity and inactivity.

OBJECTIVETo investigate the mechanism of refractoriness of acute myeloid leukemia (AML) by studying the changes of gene mRNA expression from primary diagnosis to relapsed disease in AML.

METHODSDifferences in gene expression profile of bone marrow mononuclear cells were compared between primary diagnosis and relapsed/refractory disease in 3 patients with M(2a) subtype of AML using Agilent human 1B 60mer oligonucleotide microarray.

RESULTSCommon alterations were found in 10 genes among the 20173 genes tested at relapsed/refractory disease as compared with that at primary diagnosis in 3 patients. Of these 10 genes, 7 were up-regulated while 3 down-regulated at relapse in all the 3 patients.

CONCLUSIONDevelopment of relapsed/refractory disease in AML-M(2a) might be associated with the mRNA expression changes in the 10 genes tested including DAPK1. The alteration of these genes may be indications for the early diagnosis of refractoriness of AML, and these genes might provide new therapeutic targets for the treatment of refractory AML.

OBJECTIVETo test the salivary immunoglobulin A antibody activity to Streptococcus mutans in normal with in acid environment.

METHODSStreptococcus mutans strains were isolated from 20 volunteers, serotyped by biochemical test and PCR, and genotyped by AP-PCR. Unstimulated secretions from submandibular glands and sublingual glands were collected from volunteers by modified collectors. Each identified Streptococcus mutans genotype was cultured in two groups: control group was cultured in BHI broth pH7.2 at 37 degrees C for 2 h; acid shock group were cultured in TYEG broth (pH5.5) at 37 degrees C for 2 h. Analysis of SIgA activity to Streptococcus mutans genotypes in different groups was detected by Western blot.

RESULTS(1) The SIgA of each individual could response to his own Streptococcus mutans strains and the reference strains; (2) The same individual had different SIgA activity to different genotype strains; (3) There were no significant difference between acid groups and control groups, in spite that some bands had strong or weak intensity.

CONCLUSIONSAlthough Streptococcus mutans could express acid shock proteins in stress, the present study suggests that these new proteins have no qualitative effect on the reaction of SIgA to Streptococcus mutans.
