Chinese Journal of Biochemical Pharmaceutics 2017;37(9):112-113
Objective To study and analyze the effect of quinolones combined with psychological intervention on the patients with urinary tract infection. Methods 100 patients with urinary tract infection in Jiande the first people's hospital from January 2015 to December 2016 were selected as the the study subjects. They were randomly divided into two groups, the control group and the experimental group, 50 cases in each group. The control group were given Ceftezole sodium and other cephalosporins drug treatment, patients in the experimental group were ciprofloxacin treatment, two patients underwent renal protection, treatment for 12 cycles. The therapeutic effects in the experimental group and the control group were compared and analyzed. Results In the experimental group, 47 cases was effective, the effective rate was 94.0%;In the control group, 37 cases was effective, and the effective rate was 74.0%. The effective rate in the experimental group was significantly higher than that in the control group(P<0.05). The adverse reaction rate in the experiment group was 2%(1/50), and 4%(2/50) in the control group, the difference was no statistically significant. Conclusion The combination of quinolones and psychological intervention on the treatment of the patients with urinary tract infection is effective, which can can significantly improve the efficiency of treatment of infection, high safety.

Objective To generate a comD gene knock-out mutant of Streptococcus pneumoniae,and determine the correlation of comD gene and the bacterial resistance against β-lactam antibiotics and understand the effect of closantel down-regulating comD, comE and comC mRNA levels. Methods A suicide plasmid pEVP3comD was constructed for comD gene knock-out and a comD gene knock-out mutant (comD-)was generated through homologous recombination and insertion inactivation. PCR and immunofluorescence method were used to identify the comD- mutant and real-time fluorescence quantitative PCR was applied to detect the changes of comD, comE and comC mRNA levels before and after closantel treatment in comD-mutant and wild-type strain. Double agar dilution method was performed to determine the sensitivity of comD- mutant and wild-type strain to penicillin G and cefotaxime. Results The comD gene in genome DNA of the generated comD- mutant was inactivated by sequencing and immunofluorescence detection. 50 μ mol/L or 100 μmol/L closantel had a function to down-regulate the comD, comE and comC mRNA levels ( P < 0. 05) whereas 25 μmol/L closantel did not. Both the MIC values of penicillin G and cefotaxime inhibiting comD- mutant were 32 μg/ml which was significantly higher than that of wild-type strain (0.06 μg/ml and 1 μg/ml). Conclusion In this study a comD gene knock-out mutant of S. pneumoniae was successfully generated. There is a close correlation between comD gene and β-lactam antibiotics resistance of S. pneumoniae. Closantel has a function to inhibit the competence formation of S. pneumoniae through down-regulating the transcription levels of comD, comE and comC genes.

Objective To investigate the relationship between dyslipidemia and distant metastases in pa-tients with hormone receptor( HR) negative breast cancer,and to explore the impact of blood lipid change during chemotherapy on clinical response.Methods We collected the complete clinicopathological data and fasting blood lipid in 154 patients with HR negative breast cancer.The secondary blood lipid level were measured on day14 after two cycles of chemotherapy in patients with distant metastases.Single factor chi -square test was choosen to analyze the relationship between clinicopathological characteristics,including baseline lipid level,and distant metastases,then independent risk factor for distant metastases were evaluated by logistic regression model. Data about altered blood lipid and clinical response analysis were performed using paired t-test pre-or post-chemotherapy.Results Our results from single chi-square test showed that distant metastasis from breast canc-er was significantly associated with tumor size,local lymph node metastases,grade,higher total cholesterol( TC) , higher triglycerides(TG)and higher low-density lipoprotein(LDL)(P<0.05).For distant metastases,inde-pendent risk factors were tumor size(OR=1.563),local lymph node metastases(OR=1.983),higher TC(OR=1.502),higher TG(OR=1.877).Decreased trend of TC,TG and LDL and increased trend of HDL were showed in disease control( PR+SD) group,and TG had significantly tend in objective response( PR) group.Conclusion Hyperlipidmia is significantly associated with distant metastases in patients with HR negative breast cancer,andblood lipid levels decrease with effective anti -tumor chemotherapy.Dynamic monitoring of blood lipid levelscould be a candidate surrogate biomarker for outcome prediction and distant metastases in patients with HR negativebreast cancer.

Objective To study the optimal dose of esmolol for maintaining cardiovascular stability in patients with hypertension during tracheal extubation. Methods In post-anestheisa care unit, hypertensive patients after general anesthesia meeting the extubation criteria were included. Patients were divided into 2 groups according the age: group Ⅰ (>65 years old for the elderly hypertensive, 21 cases), and groupⅡ(≤65 years old for the non-elderly hypertensive, 22 cases). All the patients received esmolol bolus before sputum suction and tube extraction, and the tracheal extubation were extubated 2 minutes after esmolol bolus. The systolic blood pressure, diastolic blood pressure and heart rate were was recorded before tracheal extubation, 2 min after esmolol bolus, at the time of sputum suction extubation, 1 min after tracheal extubation, 3 min after tracheal extubation and 5 min after tracheal extubation. Esmolol dose was determined by the up and down method. Initial dose was 0.5 mg/kg, in accordance with the arithmetic dose (0.2 mg/kg) increasing or decreasing progressively. In negative results (the systolic blood pressure at extubation or 5 min after extubation ≥ 20% of the base, or the systolic blood pressure at sputum suction extubation>180 mmHg, 1 mmHg=0.133 kPa) esmolol dose increased progressively, and in positive results (the systolic blood pressure at extubation or 5 min after extubation<20%of the base) esmolol dose decreased progressively. When the crosspoint (from positive to negative result) reached 6, the study was terminated. Results The median effective doses of esmolol for maintaining cardiovascular stability in groupⅠand groupⅡwere (0.6 ± 0.1) and (0.8 ± 0.1) mg/kg. Conclusions Esmolol can maintain cardiovascular stability in patients with hypertension during tracheal extubation. Median effective dose decreases in older hypertensive patients.

The aim of this paper is to report the study on gene silencing efficiency of siRNA targeted against mouse VEGFR2 (siVEGFR2) in vitro mediated by polyethyleneimine (PEI) and its anti-tumor effect in vivo. CY3-labeled siRNA was compounded into PEI and transfected into MS1 cells. Confocal microscopy was used to image the subcellular distribution of siRNA in MS1 cells. Semi-quantitative RT-PCR and Western blotting were used to evaluate VEGFR2 gene silencing induced by siVEGFR2/PEI complexes. A tumor-bearing nude mice model was established to compare the anti-tumor effect after delivered by local and systemic routes. siVEGFR2/PEI complex-transfected cells exhibited much fluorescence in cytoplasm with no evidence of nuclear accumulation. The expression levels of VEGFR2 mRNA and protein in PEI-transfected cells were significantly down-regulated compared with that in blank group, the silencing efficiency were 28.2% and 23.6% respectively. The tumor sizes in mice intratumorally injected with siVEGFR2/PEI complexes (189.429 +/- 17.562 mm3) were reduced definitely compared to that in mice injected with siVEGFR2/PEI complexes via vein route (315.507 +/- 20.491 mm3), or to saline groups (365.844 +/- 20.713 mm3). The study demonstrated that PEI could effectively transfect siRNA into cells and silence the VEGFR2 gene expression. Intratumoral delivery is more suitable for non-targeted modified PEI/siRNA complexes to inhibit the tumor growth in vivo. The present data lay a solid foundation to further study on the gene silencing mechanism for PEI-medicated RNAi and its anti-tumor efficiency in vivo.
