Objective To study the inhibitory effects of stachyose on the hyperacute rejection in pig-to-human heart xenotransplantation.Methods A pig-to-human xenogeneic heart transplantation model was established based on an in vitro free heart blood perfusion system.The pig hearts were di- vided into two groups:group A(pig hearts treated with human blood perfusion as control)and group B(pig hearts treated with human blood plus stachyose perfusion).After perfusion for 1h,the heart xenografts were examined for deposit of lgG and IgM by immunohistochemistry and pathological analy sis.Results The mean survival time of perfusion hearts in groups A and B was(9.5?2.5)min and (46.8?8.1)min respectively(P

Objective:To make a prospective study on the effectiveness and safety of toremifene (TOR) combined with novelbine/cisplatin (NP) in the treatment of patients with advanced non-small cell lung cancer (NSCLC) whose first line platinum-based chemotherapy was failure. Methods:Forty-four patients with stage ⅡB-Ⅳ NSCLC, who failed in the first line cisplatin-based chemotherapy from January 2004 to February 2006, were enrolled in this study. All the patients received TOR combined with NP second line chemotherapy for two cycles. The response rate and adverse reaction were evaluated. The survival rate was analyzed.Results:The 44 patients received average 1.8 cycles of chemotherapy (1-3 cycles). The response of 37 patients could be evaluated including 21 patients who received NP regimen before and 16 patients who received platinum-based chemotherapy. After second line therapy, 4 of the 37 patients had partial response (PR), 19 had stable disease (SD), 14 had progressive disease (PD), and no patient had complete response (CR). The total response rate (CR+PR) was 10.8% (4/37). The disease-controlling rate (CR+PR+SD) was 62.2% (23/37). The response rate and disease-controlling rate of squamous cell lung cancer (SCC) were 27.3% (3/12) and 72.7% (8/12), which were significantly higher than adenocarcinoma [0% (0/18) and 44.4% (8/18), P<0.05]. The median survival time was 8.2 months, the median time for SD was 4.0 months (1.0-10.2 months), and the 1-year survival rate was 24.4%. The median survival time and 1-year survival rate of SCC patients had no significant difference compared with adenocarcinoma patients (9.2 vs 7.1 months; 33.3% vs 27.7%, P＝0.72). There was no significant difference in survival rate between male and female patients. One patient stopped therapy for liver function injury (hyperbilirubinemia). The adverse reactions induced by chemotherapy mainly included gastrointestinal reaction, bone marrow suppression, and liver function injury. No serious adverse reaction occurred. Conclusion:The clinical efficacy of second line TOR combined with NP regimen is similar with the first line regimen for NSCLC patients, especially for SCC patients. The frequency of adverse reaction is not increased.

Objective To investigate the rationality and safety of dengzhanxixin injection used in elderly inpatients. Methods The clinical data of 986 inpatients including 620 males and 366 females were collected, and questionnaires containing age, sex, discharge diagnosis, symptoms, drug dosage, course of treatment, laboratory examination, adverse drug reaction and drug effect were analyzed. Results For the 986 cases, the average age was(74.3±7.5)years. The average dose of dengzhanxixin injection was (38.2±4.4) ml, once daily by intravenous drip, and the average period of treatment was (10.8±5.2) days. The adverse reaction rate was 0.81%. The levels of blood glucose and hemoglobin were decreased after treatment(t orμ=1226.5,2620.0, both P<0.05), but there were no statistical differences in the levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatinine (CREA), blood urea nitrogen (BUN) and white blood cell count (WBC) before and after treatment (t or μ=122.5, 405.0, 513.5, 996.5, 956.5, all P>0.05). Conclusions It is safe to use dengzhanxixin injection according to the medication description for elderly inpatients.

OBJECTIVE Evaluation of imaging navigation system during endoscopic sinus surgury and compared endoscopic sinus surgery with and without image guidance, analyzing a number of parameters that can impact on efficacy. METHODS Retrospective review of 76 imaging-navigated endoscopic sinus surgery with image-guidance systems at our department between Jan 2000 and May 2003, including 20 consecutive pituitary adenoma patients and 10 nasal-sinus ossifying fibroma. The control group consisted of 10 nasal-sinus ossifying fibroma patients between Jan 1997 and May 2003 and 20 consecutive pituitary adenoma patients between Jan 1999 and May 2003 who underwent ESS without image guidance. The main outcomes measured were analysis of the using times of different diseases, the user's satisfication in different diseases, and compared pituitary adenoma/ossifying fibroma ESS with and without image guidance. RESULTS The using times of different diseases are different, the user feel satisfication in all cases but the degree is different with diseases. The patient's characterisitics of the two groups of pituitary adenoma/ossifying fibroma were similar in age and gendle. There are no statistically significant differences in estimated blood loss, operative time, anesthesia time. CONCLUSION Imaging navigation systems in different nasal-sinus diseases are all useful. Our experience illustrates the importance of the learning curve, we believe that the problems we had with those systems were largely operator-dependent and that these can be overcome with proper experience and training. For small group patients, it's no evidence to show in ESS can make more complete resection of nasal-sinus ossifying fibroma, but has evidence to show no more cost.

Objective To evaluate the value of MSCT and MRI in diagnosis of early postoperative complications of inguinal hernia repair (IHR).Methods Imaging and clinical data in 1 6 patients with early complications of IHR were analyzed retrospectively.Re-sults Among the complications,postoperative infection in 2 was found including incision infection in 1 and groin cellulitis in other 1. CT showed swelling abdominal wall and heterogeneous enhancement for incision infection,and inguinal mass,deep inguinal ring thickening,edema of residual sac with fluid and air collections for groin cellulitis.Seroma was found in 8,and CT and MRI demon-strated residual sac effusion,spermatic cord thickening and spermatic vascular tortuosity.Residual sac edema was found in 4,and CT and MRI showed thickening spermatic cord without effusion in residual sac or scrotum.Effusions between patch and anterior abdom-inal wall were detected by MRI in 2,one of which was accompanied by patch shrinking.Conclusion With specific clinical background for early complications of IHR,MSCT and MRI provide more anatomical information of inguinal region,which may contribute to di-agnosis and treatment of early postoperative complications.

Inorganic/polymer hybrid star polylactic acid (POSS-PLA) was obtained through ring-opening polymerization of lactide by using polyhydroxyl cage silsesquioxane (POSS-OH) as the core and tin (II) octoate as the catalyst. The star polylactic acid (POSS-PLA) was used to modify sodium alginate hydrophobically and a drug carrier was obtained. The drug release behavior was investigated by using ibuprofen as the model drug. The results showed that the drug loading rate could be improved and the release rate was postponed with an increase of POSS-PLA content in the carries. The release mechanism gradually changed from the first-order to the zero-order pattern after the modification.

OBJECTIVETo study the expression of Galectin-3 in human hepatocellular carcinoma (HCC) tissues and the clinical value of serum Galectin-3 in the diagnosis of hepatocellular carcinoma.

METHODSImmunohistochemistry method was used to detect the expression of Galectin-3 in the 46 pairs of HCC tissues and their para cancerous tissues. The relationship between expression levels of Galectin-3 and clinical parameters was analyzed. Serum Galectin-3 in different liver diseases were measured with ELISA. The sensitivity and specificity of galectin-3, alpha fetoprotein (AFP) and gamma-glutamyltranspeptidase II (GGT-II) for diagnosis of HCC were compared and the complementary diagnostic values of Galectin-3 and AFP and GGT-II for HCC were studied.

RESULTS(1) The positive rate of Galectin-3 in the tissue of HCC was 78.2%, dramatically higher than that in para cancerous tissues (15.2%) (P is less than 0.01). The expression levels were correlated with differentiation and with the high expression in poor differentiation tissues; (2) Based on ROC curve, the cut-off of serum Galectin-3 for HCC diagnosis was set as 0.62mug/L, the serum galectin-3 positive rate was 64.5% in HCC cases, which was apparently higher than that in liver cirrhosis, chronic hepatitis and healthy persons (P is less than 0.05); (3) Serum Galectin-3 was not correlated with AFP and GGT-II. Combined determination of the three markers had the complementary diagnostic value for HCC and might increase the diagnostic sensitivity to 94.7%.

CONCLUSIONGalectin-3 is overexpressed in HCC tissues and is correlated with the tumor differentiation, suggesting that Galectin-3 may be associated with the carcinogenesis and development of HCC. Serum galectin-3 increases in the HCC cases and combined determination of serum Galectin-3, AFP and GGT-II can increase the diagnostic efficiency for HCC. Galectin-3 could be a novel serum tumor marker for HCC.

Objective:To study influence of amlodipine combined enalapril antihypertensive therapy on renal function in aged patients with essential hypertension (EH) complicated coronary heart disease (CHD).Methods:A total of 120 aged EH + CHD patients in our hospital from Feb 2014 to Apr 2016 were enrolled.Patients were randomly and equally divided into amlodipine group,enalapril group and combined treatment group (received amlodipine com-bined enalapril treatment ),all groups were treated for 12 weeks.Total effective rate,standard-reaching condition of blood pressure,urinary albumin excretion rate (UAER),levels of serum creatinine (Scr),cystatin C (CysC) and blood urea nitrogen (BUN) before and after treatment,and incidence of adverse reactions were measured and com-pared among three groups.Results:There was no significant difference in total effective rate among three groups,P＝0.139.Compared with amlodipine group and enalapril group,there was significant reduction in standard-reaching time of blood pressure [ (10.84 ± 2.79) months vs.(10.75 ± 3.31) months vs.(8.20 ± 1.46) months] in com-bined treatment group,P＝0.001 all.Compared with before treatment,after 12-week treatment,there were sig-nificant reductions in UAER,levels of Scr,serum CysC and BUN in amlodipine group and combined treatment group,P＜0.05 or ＜ 0.01;compared with amlodipine group and enalapril group after 12-week treatment,there were significant reductions in UAER [(130.55 ± 12.72) μg/min vs.(135.63 ± 17.64) μg/min vs.(112.25 ± 13.34) μg/min],levels of Scr [ (79.32 ± 6.13) μmol/L vs.(80.25 ± 5.97) μmol/L vs.(68.04 ± 5.56) μmol/L],serum CysC [ (1.14 ± 0.23) mg/L vs.(1.21 ± 0.26) mg/L vs.(0.76 ± 0.17) mg/L] and BUN [ (5.16 ± 1.13) mmol/L vs.(5.79 ± 1.03) mmol/L vs.(4.23 ± 0.56) mmol/L] in combined treatment group,and BUN level of amlodip-ine group was significantly lower than that of enalapril group,P＜0.05 or ＜0.01.There was no significant differ-ence in incidence rate of adverse reactions during treatment among three groups,P＝0.757.Conclusion:Small dose amlodipine combined enalapril is effective on controlling blood pressure in aged EH + CHD patients.Compared with monotherapy,it possesses better protection on renal function with high safety,which is worth extending.

OBJECTIVEIn order to understand the epidemiological and virologic characteristics of coronavirus HKU1 infection in hospitalized children with acute respiratory tract infection (ARTI) in Changsha.

METHODS1165 nasopharyngeal aspirates (NPA) specimens were collected from hospitalized children with ARTI between September 2007 and August 2008 in Changsha. Specimens were screened for pol gene of coronavirus HKU1 by polymerase chain reaction. All positive amplification products were confirmed by sequencing and compared with those in GenBank.

RESULTSCoronavirus HKU1 were detected in 12 patients (1.03%) out of the 1165 children. The patients were from 8 days to 3 years. The most common clinical diagnosis was bronchopneumonia(83.33%). Similarity of coronavirus HKU1 with those published in the GenBank at nucleotide levels was 98.18% - 100%.

CONCLUSIONCoronavirus HKU1 may be important pathogens in children with acute lower respiratory tract infection. Coronavirus HKU1 infections are common in children under 3 years old. There is no significant difference in the infectious rate between the boys and the girls. The peak of its prevalence is in spring and winter. A single genetic lineage of Coronavirus HKU1 was revealed in human subjects in Changsha.
