AIM: To explore the effects and mechanism of cobra venom serum on the proliferation in HL60 cells. METHODS: Established the HL60 cells as a target to study the growth feature by the action of cobra venom serum. The agarose gel electrophoresis and flow cytometry analysis were used to demonstrate apoptosis. RESULTS: Compared with the control group, the cells were inhibited significantly by the action of cobra venom serum. A characteristic DNA "ladder" was detected by using agarose gel electrophoresis. By flow cytometry analysis, it was proved that most apoptosis of HL60 cells occurred when cultured with cobra venom serum. CONCLUSION: Cobra venom serum inhibited the HL60 cells in vitro, which was related to apoptosis. This may introduce a new way to the treatment of leukemia.

OBJECTIVETo evaluate the clinical efficacy of Shenfu Injection (SFI), as a adjuvant therapy, in treating patients of ischemic cardiomyopathy with heart insufficiency (ICP-HI).

METHODSOne hundred patients of ICP-HF were equally randomized into two groups, the SFI group and the control group. All received the conventional treatment, but to patients in the SFI group SFI was given additionally via intravenous injection, 60 mL once a day, 10 days each month, the treatment course was 6 months. Changes of cardial functional grading, 6-min walking distance, echocardiographic indices, plasma N terminal pro-brain natriuretic peptide (pro-BNP) level were observed before and after treatment, and the occurrence of major adverse cardiovascular events (MACE) and mortality in patients were observed as well.

RESULTSAs compared with the conventional treatment alone, additional application of SFI showed a more significant efficacy in improving NYHA functional grade and 6-min walking distance, reducing the diameters of left ventricular at end diastole and systole, increasing left ventricular ejection fraction, and decreasing plasma N terminal pro-BNP level (P <0.05). The occurrence of MACE and the mortality in the SFI group were significantly lower than those in the control group respectively (P <0.05).

CONCLUSIONSBased on the conventional treatment, the adjuvant therapy of SFI could improve the cardiac function, improve the quality of life, ameliorate ventricular reconstruction, and decrease the occurrence of cardiovascular events in patients of ICP-HI.

Objective To evaluate the influence of atopy on exhaled nitric oxide in chronic persistent asthmatic children. Methods A total of 52 chronic persistent asthmatic children who completed FeNO measurements and skin prick testing were enrolled. Patients were divided into non-atopic group and atopic group by skin prick testing results, and subdivided into non-allergic rhinitis and rhinitis group according to whether combined with allergic rhinitis. At the same time 78 healthy children were chosen as control group. Moreover, 32 chronic persistent asthmatic children who completed FeNO measurements twice interval of three months were enrolled. Results The FeNO level was signiifcantly different among the atopic group (n=40), the non-atopic group (n=12) and the control group (H=33.29, P=0.000);The FeNO level was signiifcantly higher in the atopic group than that in the non-atopic group (P<0.05). And the FeNO level were signiifcantly different among the rhinitis group (n=41), the non-rhinitis group (n=11) and the control group (H=30.63, P=0.000). The FeNO level was signiifcantly higher in the rhinitis group than that in the control group (P<0.05), however there were no difference between the rhinitis group and the non-rhinitis group(P>0.05).There were no correlations between FeNO levels of chronic persistent asthmatic children and the wheal diameter of house dust mites or dust mites (r=2.05, P=0.135;r=1.58, P=0.312). Moreover, the FeNO level was signiifcantly lower after 3 months ICS treatment (z=-2.05, P=0.041). Conclusions Atopy had major inlfuence on the FeNO level of chronic persistent asthmatic children, and the FeNO level declined with the theatment of ICS.

The alpha-amylase (EC 3.2.1.1) from the Gram-positive Alicyclobacillus acidocaldarius was one kind of thermoacidophilic enzyme, with optimal temperature and pH of 75 degrees C and 3, respectively. The nucleotide sequence of the gene amy was cloned by PCR. The gene amy was 3901bp long, comprising one open reading frame encoding a polypeptide of 1301 amino acids. The calculated molecular weight of the alpha-amylase AMY was about 140kD. The gene amy was expressed in E. coli BL21 (DE3) and Pichia pastoris respectively, and both of the cloned proteins had bioactivity. The activity of amylase expressed in P. pastoris was further testified by amylase activity staining. The alpha-amylase expressed in P. pastoris had been purified and characterized. The apparent molecular weight of that was about 160kD according to SDS-PAGE. The optimum of pH for the enzyme was pH 3.2 as the native enzyme was; but the optimum of temperature was 65 degrees C and a little lower than that of the native enzyme. Above 50% of relative activity remained after incubation for 30 minutes in 70 degrees C. So the enzyme expressed by P. pastoris was also thermoacidophilic. Moreover some sequence was cloned by PCR, which ranged from + 1174 bp to + 3288 bp in the gene amy, encoding 705 amino acids with the calculated molecular weight of 79kD. The truncated gene amy' was expressed in E. coli BL21 (DE3) induced by 1 mmol/L IPTG, and the expressed enzyme also retained alpha-amylase activity.

Objective To investigate the effect of health belief model on the quality of life of patients with chronic prosatitis. Methods Totally, 80 patients with chronic prosatitis were divided into the observation group and the contrast group at random and each group consisted of 40 patients. Patients in the observation group took medication and at the same time they received conventional health education in accordance with the health belief mold while the contrast group only used the routine health education. The quality of life of patients of the two groups were compared before and after the health education. Results Before the health education, the quality of life between groups showed no significance ( P ＞ 0. 05). While after the 3-month health education, the difference of quality of life betweens group was significant. Conclusions The health belief mold education can improve the quality of life of patients with chronic prosatitis.

The hybrid xylanase TB was constructed by the substitution of the N-terminus segment of the Streptomyces olivaceoviridis xylanase XYNB with corresponding region of Thermomonosporafusca xylanase TfxA. The hybrid gene tb, encoding the TB, was correctly expressed in Escherichia coli BL21 and Pichia pastoris GS115. TB was purified and its enzymatic properties were determined. The results revealed that the optimal temperature and optimal pH of TB were at 70 degrees C and 6.0, which have been obviously improved compared with those of XYNB. The thermostability of TB were all about six-fold of XYNB's after incubating the properly diluted enzyme solutions at 80 degrees C and 90 degrees C for 3min, respectively. The pH stability of TB was 5 to approximately 9, which was narrower than that of XYNB. Still, TB remains a high specific activity as XYNB does. Analysis of a homology modeling and sequence similarity were used to reveal the factors influencing the enzymatic properties of TB and the discussion for the relationship between structure and function of xylanase was given.

OBJECTIVETo analyze serum vancomycin concentration after administration of different therapeutic doses in children with Staphylococcus aureus pneumonia (SAP) in order to determine the appropriate dose of vancomycin in clinical administration.

METHODSThe clinical data of 35 children who were diagnosed with SAP and treated with vancomycin from January 2008 to December 2013 were retrospectively analyzed.

RESULTSAmong the 35 SAP cases with vancomycin therapy, 22 cases (63%) had serum vancomycin trough concentration monitored. The numbers of cases with vancomycin at 10, 12.5, and 15 mg/(kg·dose) × every 6 hours (q6h) were 11, 4 and 7, respectively. The mean serum trough concentration of vancomycin in the 15 mg/(kg·dose) group was 14.98 mg/L, which was significantly higher than in the 10 mg/(kg·dose) and 12.5 mg/(kg·dose) groups (4.97 and 8.00 mg/L respectively; P<0.05). The percentage of cases that reached the expected trough concentration in the 15 mg/(kg·dose) group (71%) was significantly higher than that in the 10 mg/(kg·dose) group (9%), but there was no significant difference in this percentage between the 15 mg/(kg·dose) and 12.5 mg/(kg·dose) groups (71% vs 25%).

CONCLUSIONSThe reasonable dosage of vancomycin for the treatment of pediatric SAP is 15 mg/(kg·dose) × q6h or 60 mg/(kg·d).

OBJECTIVETo compare the clinical manifestations between inhaled and blood-borne Staphylococcus aureus pneumonia (SAP) and the antibiotic resistance between the isolates of inhaled and blood-borne Staphylococcus aureus.

METHODSThe clinical data of 44 pediatric SAP cases in the Children′s Hospital, Chongqing Medical University from January 2008 to December 2013 were retrospectively analyzed. Twenty-four cases were identified as inhaled SAP, and 20 cases as blood-borne SAP.

RESULTSInhaled SAP was more common in children younger than 3 years of age, while blood-borne SAP was more prevalent in children older than 6 years of age. Patients with inhaled SAP had significantly higher incidence rates of cough, wheeze, moist rales, dyspnea and empyema than those with blood-borne SAP (P<0.05). The patients with blood-borne SAP were more vulnerable to severe fever, unconsciousness, dysfunction of liver and kidney, pyogenic osteomyelitis, septic arthritis, sepsis, and abscess of skin and soft tissues (P<0.05). Inhaled SAP isolates had significantly higher rates of resistance to amoxicillin/clavulanic acid, oxacillin, and cefoxitin than blood-borne SAP isolates (P<0.05), while the latter had a higher rate of resistance to cotrimoxazole (P<0.05).

CONCLUSIONSInhaled SAP often occurs in children younger than 3 years of age, and the respiratory manifestations are commonly seen. Blood-borne SAP often occurs in children older than 6 years of age, with the infectious-toxic symptoms that result in multiple organ infection and dysfunction. The isolates of inhaled and blood-borne SAP have different antibiograms.
