Objective To observe the efficacy and safety of safflower yellow injection in the treatment of sta-ble angina pectoris.Methods 70 patients with stable angina pectoris were selected and divided into observation group and control group by random number table method,35 cases in each group.The observation group used injection of safflower,and the control group used Xuesaitong.The effect was compared between the two groups.Results The total effective rate of the observation group was 94.3%,which was higher than 74.3% of the control group,the differ-ence was statistically significant(χ2 =5.285,P <0.01).The clinical indexes of the two groups after treatment were significantly improved than before treatment,the differences were statistically significant (t =13.021,25.407,3.376, 3.930,7.119,10.163,18.044,3.765,3.124,6.096,all P <0.05).The angina attack times of the observation group was less than that of the control group ,the dosage of nitroglycerin was lower than that of the control group ,the differences were statistically significant(t =4.686,6.568,all P <0.05).The incidence rate of adverse reaction was 5.7% in the observation group,compared with the control group of 8.6%,the difference was not statistically signifi-cant(χ2 =0.729,P >0.05).Conclusion The injection of safflower yellow pigment in the treatment of stable angina pectoris has high safety.

Objective To find out some ways to solve the problems which are dealing with the clinical application of intrafix.Methods From February to May 2013,324 patients with back blood using intrafix in emergency department were randomly assigned to the experimental group A and the control group A,with 162 patients in each group.The experimental group A used the method of pressing pipe while pulling out the needles when transfusion was over,while the control group A used traditional ways.206 patients who occurred bubbles in the intrafix among the above two groups were divided into the experimental group B and the control group B.The experimental group B got rid of the bubbles using top-down method,the control group B used traditional ways.The effect of withdrawing the needles and exhaustion of bubbles were compared.The least flushing time of remaining liquid using transfusion pipe flushing method was calculated.Results The experimental group A and the experimental group B were better in withdrawing the needles and exhaustion of bubbles compared with those of the control group A and the control group B.Using the method of drop coefficient to calculate the least flushing time can ensure the drug to be transfused into the body thoroughly.Conclusions When transfusion is over,pressing intrafix pipe will have a better result than the traditional way when pulling out the pipe.Top-down method can clearly settle the problem of intrafix pipe,which can not get rid of bubble via traditional way.Flushing pipe and press pipe method can apparently decrease drug waste.

Aim To study IL-8 expression of U937 cells directly induced by Pseudomonas aeruginosa(PA)and its mechanism through the mitogen-activated protein kinase pathways.Methods The expressions of IL-8 mRNA in human monocytic leukemia cell lines(U937 cells)infected by Pseudomonas aeruginosa which were in differently differentiated and its protein secretion in the supernatant of culture medium were examined by the methods of RT-PCR and ELISA respectively.And these were then to be compared with those inhibited by MAPK inhibitors.Results Pseudomonas aeruginosa was able to induce IL-8 mRNA expression and their protein secretion both in U937 cells and in PMA differentiated U937 cells and had marked time and concentration dependent relations.Pretreament of U937 cells with specific inhibitors of ERK1/2(PD98059),the kinase that activated ERK1/2,p38(SB203580)could significantly diminished the PA-induced IL-8 production(P

Objective To explore the effect of spironolactone on vascular remodeling of injuried rabbit artery. Methods 20 male New Zealand rabbits were randomly divided into two groups. The rabbit models of iliac artery angioplasty were set up by BC. After injury, control group was fed with standard forage, and experimental group was fed with standard forage and spironolactone(20mg?kg~ -1?d~ -1). The rabbits were killed four weeks after injury. The injuried segments of iliac artery were removed, and processed for histological and morphological analysis by imumohistochemistry and TD 2000 analysis system of pathology image. Results AUIEM and AUEEM in the experimental group significantly increased as compared with the control group(P0.05). Conclusion Spironolactone could improve vascular remodeling after angioploasty of iliac artery in rabbits.

Myelodysplastic syndromes (MDS) is a heterogeneous group of clone bone marrow disorders.The diagnosis of MDS can be challenging when dysplastic features are minimal and cytogenetic analysis shows no abnormalities The high sensitivity of flow cytometry (FCM) in the detection of dysplasia in myeloid lineages makes it a valuable tool to distinguish possible clonal causes of cytopenia(s) from nonclonal causes.Due to the heterogeneity and absence of specific FCM markers for MDS,the immunophenotyping of MDS by FCM remains a big difficulty.Here we will focus on how to perform immunophenotyping of MDS by FCM and the potential diagnostic,prognostic and therapeutic value of FCM in MDS.

BACKGROUND:Chronic hepatitis B virus infection can impact the biological characteristics of bone marrow mesenchymal stem cel s. Adipose-derived mesenchymal stem cel s have gained more and more attention due to their high safety, little invasiveness, easy purification and rapid proliferation. OBJECTIVE:To establish the isolation and culture method of adipose-derived mesenchymal stem cel s from patients with hepatitis B virus infection in vitro, and to observe the biological characteristics of cel s. METHODS:Adipose-derived mesenchymal stem cel s were isolated from the subcutaneous fat of hepatitis B virus infection patients by col agenase digestion and adherent method. Growth curve of adipose-derived mesenchymal stem cel s were detected by MTT method and cel phenotypes were detected by flow cytometry. The adipogenic and osteogenic differentiation potential of adipose-derived mesenchymal stem cel s were detected in vitro. RESULTS AND CONCLUSION:(1) Adipose-derived mesenchymal stem cel s from 10 patients with hepatitis B virus infection were al isolated and cultured successful y. The primary passage time of adipose-derived mesenchymal stem cel s was (8.3±1.2) days. The growth curve of cel s was“S”shaped. Cel s came into a logarithmic phase at days 3-4, and came into platform at day 7. (3) Passage 3 adipose-derived mesenchymal stem cel s highly expressed CD29, CD166, HLA-ABC and CD44, but did not express or lowly expressed CD34 and HLA-DR. (3) Adipose-derived mesenchymal stem cel s differentiated into adipocytes after adipogenic induction, and differentiated cel s were positive for oil red O staining;after osteogenic induction, adipose-derived mesenchymal stem cel s differentiated into osteoblasts that were positive for alkaline phosphatase staining. These findings indicate that the col agenase digestion and adherent method can be used to effectively isolate adipose-derived mesenchymal stem cel s from patients with hepatitis B virus infection, and the cel proliferation is rapid so that a large number of cel s can be obtained in the short term.

Objective To study the value of laparoscope in the diagnosis and treatment of high cryptorchidism. Methods 21 testes in 19 patients were performed by intraperitoneal exploration and cryptorchidopexy. Results The testes of 11 cases were located in inferior extremity of kidneys and the ones of 8 cases in superior part of internal rings.15 testes were fixed in the bottom of scrotums and 4 ones in abdominal cavity for secondary operation; absent testis was found in 1 case; 1 testis was removed due to testis dysplasia. Scrotum emphysema and hematoma occurred in 3 and 1 patients respectively. Wounds of 19 cases healed well postoperatively. 15 patients had been followed up for (3～10) months with an average of 6 months and they recovered well. Conclusions The diagnosis and treatment of high cryptorchidism by means of laparoscope has the advantages of minimal invasion, less bleeding, quicker recovery and no serious complications.
