Livin is a new member of the inhibitors of apoptosis protein(IAP) gene family. It is highly expressed in most human tumors, involved in inhibiting cell apoptosis, and closely related with tumor occurrence, development and prognosis. So Livin could be a new target for tumorous early diagnosis and cancer therapy. This paper summarizes the Livin gene molecular structure, tissue expression, biological function,and its application in cancer treatment.

AIM: To understand the effects of benazepril in treating the diastolic function of the left ventricular in patients with hypertention and coronary heart diseases(CHD).　METHODS: Forty-five hypertension patients with the left ventricular diastolic dysfunction(LVDD) received benazepril 10-20 mg, po,qd, for 5 mo. On the basis of receiving nitrates 36 CHD patients with LVDD added to receive benazepril 5 mg, po, qd, for 5 mo. Before and after the therapy, the utmost speed of the peak value at the left ventricular early diastole stage (E peak), the utmost speed of the peak value at the left ventricular late diastolic stage (A peak), the E/A ratio and peak filling rate (PFR) were determined by color Doppler echocardiography. 　RESULTS: After the therapy, the E peak, the E/A ratio and PFR were up higher than before the therapy, meanwhile the A peak dropped lower, there were significant difference respectively (P<0.01). 　CONCLUSION: The LVDD can be improved distinctly if the patients with hypertension and CHD take benazepril for 5 mo or so.

Objective: To analyze the present situation of the management of large-scale instruments in a medical school and give some reasonable suggestions. Methods: Through the research on the use of 85 large-scale instruments in our university, we tried to find out the methods of improving the utilization ratio of large-scale instruments. Results:There are many reasons of the poor management and low utilization rate of large-scale instruments in medical schools. Conclusion: Taking some measures could effectively improve the utilization rate of large-scale instruments in medical schools, such as simplifying the working procedure, solving the operating and repair expenses, strictly controlling argumentation, drawing up scientific evaluation and incentive measures and so on.

Objective:The current evidence suggests that tumor necrosis factor-inhibitor (TNFi) treatment can be used to achieve clinical remission or low disease activity in patients with ankylosing spondylitis (AS). After achieving remission / low disease activity, however, the follow-up treatment options are unclear. The purpose of this review is to conduct an extensive and systematic literature review of the studies conducted from September 2014 to July 2020 to assess the feasibility and effectiveness of tapering of biological agents.Methods:After searching for the related papers and abstracts and applying inclusion/exclusion criteria, a structured extraction process was used to include the studies into this study.Results:A total of 13/93 studies were included into the analysis of the tapering of biological agents in AS patients, in which 7/13 adopted the dose reduction regimen, 3/13 adopted the extended interval between doses regimen, and 5/13 did not provide or formulate the detailed reduction regimen. We summarized the feasibility of TNFi tapering schemes in the published studies and summarized the tapering rules. Only one study showed that reduced TNFi levels worsened the quality of life and resulted in a relapse within 12 months.Conclusion:More research is needed to understand the long-term effects of these strategies on efficacy, safety, and cost in the treatment of AS.

Objective To isolate and identify the components from the stem barks of Morus yunnanensis.Methods The compounds were isolated and purified by silic gel column,Sephadex LH-20,and RP-18 chromatography.Their chemical structures were elucidated on the basis of physicochemical properties and spectral data.Results Eleven compounds were isolated and identified as:mulberroside C(1),oxyresveratrol(2),2',4',7-trihydroxy-(2S)-flavone(3),norartocarpetin(4),moracin P(5),betulinic acid(6),sitosteryl 3?-glucoside 6'-O-palmitate(7),lupeol(8),betulinic acid(9),?-daucosterol(10),and ?-sitosterol(11).Conclusion All the compounds are isolated from the plant for the first time,and compound 9 shows cytotoxic activities.

Objective To study telomere dynamics in bone marrow from patients with leukemia and myelodysplastic syndromes (MDS) by flow cytometry and FISH (FLOW FISH) Methods By FLOW FISH , we detected telomere lengths of leukocytes in bone marrow from 43 leukemia patients and 48 healthy donors The mean fluorescence intensity of cells (Q FISH) was detected by flow cytometer Results Compared with the age matched normal range (0 066?0 015), 38 of 43 patients had shortened telomere length (0 047?0 019), and the remaining patients (3 MDS and 2 chromic phase CML) had normal telomere lengths (0 069?0 007 vs 0 060?0 008) Although no significant difference in telomere lengths could be demonstrated in 8 leukemia patients at diagnosis and follow up, a trend toward telomere shortening was observed in CLL patients with 0 052 vs 0 048 in which telomere tended to shorten as the disease went on In contrast, longer telomeres were found in AML patients after induction chemotherapy (0 056) compared with those found in diagnostic specimens (0 043) In the healthy donors, the telomere length turned to be shorter with increase of age ( r =0 67), whereas in leukemia and MDS patients, the telomere length had no correlation with age ( r =0 14) Conclusion The telomere lengths from most patients with leukemia and MDS were shorter than that of healthy donors The telomere dynamics is associated with prognosis and therapy of disease

OBJECTIVE To investigate the bacterial distribution and the extent of drug resistance in lower respiratory tract disease among aged people.METHODS From Jan 2006 to Dec 2006 we collected 304 sputum samples of the old patients who were diagnosed lower respiratory tract infection,bacterial distribution and antibiotic resistance of 178 strains of the pathogens were analyzed retrospectively.RESULTS The most common four kinds of Gram-negative bacilli were Pseudomonas aeruginosa,Klebsiella pneumoniae,Escherichia coli and Acinetobacter baumannii.For above bacteria,the ratio of the resistance to ampicillin,cefazolin and compound sulfamethoxazole was over 40%.The isolating rate of ESBLs-producing E.coli and K.pneumoniae was 29.8%.CONCLUSIONS Monitoring the common bacteria and ESBLs bacteria precisely can provide therapy,guide to early cure and control lower respiratory tract infection of aged patients effectively.

Objective To investigate the causes and influence factors of fungous infection pneumonia. Methods A total of 96 patients admitted by our hospital from Jan 2000 to Dec 2004 with fungous infection pneumonia were retrospectively analyzed. Results All pulmonary fungous infection patients, aged 78 years in average, had severe basic diseases and employed polyantibiotics. The risk factors included abusive usage of antibiotics and polyantibiotic, immunosuppression and malnutrition. Blastomyces albicans was the main pathogen in the infection of pulmonary fungus. Conclusion The main risk factor of hospital acquired fungous infection pneumonia is abusive usage of antibacterial and the existence of the basic diseases.
