Objective:To evaluate the therapeutic effects and pharmacoeconomic results of four proton-pump inhibitors in the duo-denal ulcer patients with hemorrhage. Methods:Using a retrospective analysis, 90 duodenal ulcer patients with hemorrhage were in-volved. According to the proton pump inhibitors, there was no statistic difference among those groups(P>0. 05). The mean time to stop bleading,hemostalsis rate,and the incidance of adverse drug reactions of those four groups,there were no statistic differece too( P>0. 05). The cost of pantprazole group was much lower than the other three groups by cost-minimication analysis. Results:The effective rate of the four groups was 80. 0%, 86. 7%, 90. 0% and 90. 0%, respectively;there was no statistic difference among those groups(P>0. 05). The mean time to stop bleeding, hemostasis rate, and the incidence of adverse drug reactions of those four groups, there were no statistic difference too(P>0. 05). The cost of pantoprazole group was much lower than the other three groups by cost-minimization alanysis. Conclusion:The effect and safety of the four groups were basically equivalent, while the coot of pantoprazole is lowest, it is the best treatment plan by pharmacoeceonomics.

OBJECTIVE:To provide reference for rational use of antibiotics in patients with AECOPD. METHODS:The patho-gen distribution and antibiotics use of AECOPD patients was analyzed in respiratory department of our hospital during 2014-2015. The infection site,pathogen distribution and antibiotics use(including medication purpose,drug name,usage,dosage,medication duration,route of administration,drug combination),infection and compliance were investigated and analyzed statistically. RE-SULTS:Among 967 AECOPD patients,there were 619 cases of positive sputum culture(64.01%). A total of 774 strains were iso-lated,including 542 strains of Gram-negative bacterial (70.03%) and 232 strains of Gram-positive bacterial (29.97%);most of them were Pseudomonas aeruginosa(207 strains,26.72%). 765 patients were treated with antibiotics,and utilization ratio of an-tibiotics was 79.11%. 276 cases were treated with one kinds of antibiotics (36.08%),435 treated with 2 kinds of antibiotics (56.86%)and 54 treated with 3 kinds of antibiotics and above(7.06%). Top 3 drugs in the list of frequency were Levofloxacin injection(455 cases/times,47.05%),Moxifloxacin injection(241 cases/times,24.92%)and Cefmetazole for injection(192 cas-es/times,19.86%). Top 3 drug combination regimen were Cefmetazole for injection+Levofloxacin injection (107 cases/times, 21.88%),Cefoxitin for injection+Levofloxacin injection(96 cases/times,19.63%)and Moxalactam for injection+Levofloxacin in-jection(65 cases/times,13.29%). CONCLUSIONS:Anti-infective therapy regimen of AECOPD patients should be formulated ac-cording to relevant guideline,and pathogenic factors of infection are analyzed. Great importance should be attached to reasonable, scientific,safe and standard use of antibiotics,etiological examination;pathogenic bacteria culture and drug sensitivity test should be conducted as soon as possible. So as to obtain better therapeutic efficacy and reduce the generation of drug-resistant strain.

Objective:To investigate the effect of IL-6?TNF-? and TGF-? 1 on the occurrence and development of DM and DN.Methods:To observe the changes of IL-6?TNF-? and TGF-? 1 amount in normal group ?DM group and DN respectively .Results:The amount of IL-6?TNF-? and TGF-? 1 in DM group and DN group are markedly higher that in normal group.The amount of IL-6?TNF-??TGF-? 1 in DN is markedly higher than that in DM group.Conclusion:IL-6?TNF-? and TGF-? 1 play an very important role in the occurrence and development in DM and DN.

Hyperhomocysteinemia is an independent risk factor for arterial and venous obstructive vascular di-seases. Raised plasma homocysteine concentrations are caused by genetic and non-genetic factors. The pathogenic mechanism is not clear. It may be associated with endothelium dysfunction, abnormal lipid metabolism, hypertrophy of intima media, increased platelet aggregation and several clotting factors interfered, etc. The metabolism and pathogenic mechanism of homocysteine are reviewed in this article, which provides theoretical foundation for the treatement of hyperhomocysteinemia.

Objective:To observe effects of Tongmai Yizhi Capsules on trace elements in the patient of vascular dementia.Methods:Blood trace elements Cu,Se,Zn and Fe contents before and after treatment were investigated in a Tongmai Yizhi Capsules group(n= 50)and a Hydergine group(n=30).Results:After treatment Cu,Se contents increased and Zn and Fe contents decreased in Tongmai Yizhi Capsules group with significant difference as compared with Hydergine group(P

BACKGROUND: Reports regarding adipose-derived stern cells (ADSCs) differentiation into dopaminergic (DN) neurons are few in addition, there is not experimental evidence of the effect of ADSCs on maintaining the survival of DN neurons.OBJECTIVE: To investigate the effect of glial cell-derived neurokophic factor (GDNF)-modified adipose-derived stem cells on survival of DN neurons under co-cultured condition.DESIGN, TIME AND SETrlNG: The in vitro cytology experiment was conducted at the Institute of Otolaryngology-Head and Neck Surgery and Key Laboratory of Zoonoses of Ministry of Education between March and December 2007.MATERIALS: Wistar rats with 3-weeks-old, or 14 days of pregnancy were provided by Norman Bethune College of Medicine, Jilin University.METHODS: The GDNF recombinant adenovirus was constructed by using pAdTrackCMV and pAdEasy-1 system. DN neurons were obtained from the rostral mesencaphalic tegmentum of Wistar rat embryos by using trypsin and collagenase method. ADSCs isolated from rat inguinal fat pads were digested with collagenase Ⅱ, cultured and passaged in vitro. When the cells reached 60% cenfluency at the 3rd passage, cells were transfectad with 1×109vp/mL of Ad-GDNF for 1 hour and then transferred into growth medium for another 24 hours, and GDNF level in cell supematant was detected by ELISA assay. Meanwhile, the co-cultured of ADSCs and DN neurons were carried out for following 7 days. With GFP-modified ADSCs was served as a control group.MAIN OUTCOME MEASURES: The effect of co-cultured condition on the survival of DN neurons, as well as the differentiation of GDNF-modified ADSCs was detected by immunofluorescence staining.RESULTS: GDNF appeared in ADSCs supematant at 24 hours after Ad-GDNF transfection and reached a peak at 72 hours.There was approximately 80% GFP-positive labeled in ADSCs. The tyrosinase hydroxylase staining results demonstrated that the rate of survival DN neurons were significantly increased than in DA neurons cultured alone, co-cultured group of GFP-modified ADSCs and GDNF-modified ADSCs groups (55%, 15%, 25%, P < 0.01). However, there were no co-expressing TH and GFP positive cells appeared at 7 days of co-culture, which indicated that the co-cultured condition was not available to ADSCs differentiation.CONCLUSION: The co-cultured of GDNF modified ADSCs and DN neurons can promote the survival and growth of cultured DN neurons, however, it can not induce ADSCs differentiate into DN neurons.

Silibinin, from milk thistle (Silybum marianum), is a flavonolignan with anti-oxidative and anti-inflammatory properties. It has been therapeutically used for the treatment of hepatic diseases in China, Germany and Japan. Recently, increasing evidences prove that silibinin is also a potent antitumor agent, and the major anti-tumor mechanism for silibinin is the prominent inhibition of the activities of receptor tyrosine kinases (RTKs) and their downstream signal molecules in a variety of tumor cell lines, such as epidermal growth factor receptor 1 (EGFR) and insulin-like growth factor 1 receptor (IGF-1R) signaling pathways. Meanwhile, the evidences that silibinin selectively scavenges hydroxyl free radical (*OH) and specifically inhibits the action of nuclear factor kappaB (NF-kappaB) provide more complicated explanations for its antioxidant and anti-inflammatory effects. Some new findings such as that silibinin attenuating the cognitive deficits induced by amyloid beta protein (Abeta) peptide through its antioxidative and anti-inflammatory properties is valuable to broad the medical prospect of silibinin. In this review, we discuss the molecular pharmacological mechanisms of silibinin, focusing on its inhibition of tyrosine kinases, actions of antioxidation, free radical scavenging, immunoregulation and anti-inflammation.
