Objective To explore the changes of myocardial enzymes,hepatic function,renal function and 8-iso-prostaglandin F2?(8-iso-PGF2?)in newborn infants with hyperbilirubinemia and their relationships.Methods One hundred and twenty-six neonates who were 2 to 7 days old were selected.Seventy-six cases were hyperbilirubinemia,and according total bilirubin(TB),they were divided into hyper bi-lirubinemia A group(HBE-A)(51 cases,TB 205-341 ?mol/L)and hyperbilirubinemia B group(HBE-B)(25 cases,TB≥342 ?mol/L).Fifty newborn infants with physiologic jaundice were control group(TB

Objective To investigate the resistance of Staphylococcus aureus (S.aureus) to vancomycin and linezolid in Sichuan Province, and provide reference for clinical anti-infection treatment.Methods S.aureus and methicillin-resistant S.aureus(MRSA) from 71 hospitals in Sichuan Province in 2011-2015 were collected, minimum inhibitory concentration(MIC) values of vancomycin and linezolid against S.aureus and MRSA in each year were calculated.Results A total of 51 976 strains of S.aureus were collected in 5 years, 14 361 of which were MRSA, isolation rate of MRSA decreased from 36.02％ in 2011 to 25.56％ in 2015, which showed a downward trend (x2=160.72,P<0.05).From 2011 to 2015, MIC50 of vancomycin against S.aureus were 1, 0.5, 0.5, 1, and 1μg/mL respectively,MIC90 increased from 1μg/mL to 2μg/mL;the mean MIC50 of linezolid was 2μg/mL,MIC90 increased from 2μg/mL to 4μg/mL.Change in MIC50 and MIC90 of vancomycin against MRSA in 2011-2015 were obvious, which increased from 0.5, 1μg/mL to 2μg/mL respectively;the mean MIC50 of linezolid was 2μg/mL,MIC90 increased from 2μg/mL to 4μg/mL.Conclusion The isolates rate of MRSA had a decreasing trend,but there is a upward trend of MIC50 and MIC90 of vancomycin and linezolid against MRSA, bacterial resistance surveillance needs to be strengthened to provide evidence for rational clinical antimicrobial therapy.

Objective:To test the role of tumor necrosis factor-?(TNF-?)in acute lung injury and study new treatment.Method:The rabbit acid aspiration models were induced with 0.1N hydrochloric acid (HCI). Twenty rabbits were divided randomly into HCl group,verapamil and vitamin C groups.The plasma levels of TNF-? and malondialdehyde (MDA) were measured,and polymorphonuclear neutrophils (PMN)were counted in lung tissue of all animals. Result:There were increases in TNF-?,MDA and PMN after acid aspiration,which can be inhibited by verapamil and vitamin C. Conclusion:PMN can be induced by TNF-?.Vitamin C and verapamil provide a obvious protection on pulmonary tissue after acid aspiration.

OBJECTIVE: To explore the possibility mechanism of non-side population cells (NSP) of Hep-2 be induced into stem-like cancer cells by chemotherapy drug--cisplatin. METHOD: Hep-2 cell lines were sorted by fluorescence-actived cell sorting. The acquired NSP cells in trail group were co-cultured with cisplatin for more than 48 hours,while the control group with normal saline(NS). Then identified the percentage of the side population (SP) cells by flow cytometer. The β-catenin, notch-1 mRNA in trial and control group were detected using quantitative realtime PCR, and the β-catenin, notch-1 protein in two groups were compared by Western blot. RESULT: The percentage of side population cells in two groups were (17.16 ± 0.18)%, (10.05 ± 1.20)%, respectively. There was significant difference between two groups (t = 5.844, P < 0.01). The expression of β-catenin, notch-1 was higher in trail group by qRT-PCR; the protein levels of β- catenin, notch-1 was found to inceased in the trail group by Western blot (t = 5.155, P = 0.031; t = 5.977, P = 0.004). Statistical analysis showed significant difference between two groups (P < 0.05). CONCLUSION NSP cells can be differentiated into stem-like cancer cells after being treating with cisplatin. The supposed mechanism is maybe through wnt/β-catenin, notch signaling transduction pathway abnormalities.

Objective To understand the molecular epidemiology characteristics and its drug resistance of methicillin-resistant Staphylococcus aureus (MRSA) in the urban area of Jilin and to provide important basis for guiding the clinical medication and prevention of the MRSA infection. Methods One hundred and three strains of MRSA from July 2013 to July 2014 in the urban area of Jilin were selected. The polymerase chain reaction (PCR) technology and multiple polymerase chain reaction were used to detect mecA gene and Staphylococcus chromosomal cassette mec typing (SCCmec) genotype of MRSA. The drug sensitivity test for 13 kinds of clinical common antibacterial drugs were detected by using the K-B method. And the source of the strains were analyzed. Results The results of SCCmec genotype of MRSA showed that SCCmecⅢtype were 62 strains, accounting for 60.2%;SCCmecⅡtype were 39 strains, accounting for 37.9%; failing to parting were 2 strains,accounting for 1.9%. Drug susceptibility test results showed that all of 103 MRSA strains were resistant to cefoxitin, cefazolin, penicillin and benzene, and drug resistance rate was 100.0%. The resistant rate to erythromycin, levofloxacin, ciprofloxacin, tetracycline, gentamicin and rifampin were 96.1%, 93.2%, 95.1%, 91.3%, 90.3%and 55.3%receptively;the resistant rate to sulfamethoxazolewas was only 1.9%;and the resistant strains to vancomycin and teicoplanin were not detected. The top three department of the distribution of the strains source were department of neurosurgery (31.1%), ICU (19.4%) and burn plastic surgery (17.5%). Conclusions The SCCmecⅢtype is the main MRSA epidemic strains, and SCCmec type II is a minor epidemic strainin the urban area of Jilin. The antibiotic resistance of MRSA is a serious problem with multiple drug resistance, but MRSA is sensitive to vancomycin and teicoplanin.

Saw palmetto fruit extract (SPE), as a herbal product, is widely used for the treatment of benign prostatic hyperplasia (BPH) and lower urinary tract symptoms (LUTS). Recent studies show that SPE also has some therapeutic effects on chronic prostatitis, prostate cancer, sexual dysfunction, and so on. This article presents an overview on the application of SPE in the treatment of BPH, prostate cancer, and chronic prostatitis/chronic pelvic pain syndrome, with a discussion on its action mechanisms.

OBJECTIVE To know the clinical antibacterial use by line category in pediatric outpatients and emergency departments.METHODS The antibacterial use by line category from the 38998 prescriptions of pediatric outpatient and emergency departments of a hospital from Jul 1st to Dec 31st 2008 according to the medicament amount and frequency were surveyed and analyzed.RESULTS First-line antibacterial drug DDDs accounted for 37.4% and 24.7% of the total amount;second-line drug DDDs accounted for 48.7% and 40.8% of the total amount and the third-line drug DDDs accounted for 13.9% and 35.0% of the total amount.The top three by total amount were cefmetazole sodium injection,azithromycin sodium injection and Cefuroxime sodium injection.According to the sorting method of DDDs,the top three were cefprozil dry suspension,azithromycin sodium injection and amoxicillin sodium clavulanate potassium injection.CONCLUSIONS Frequency of the third-line antibacterial drug using is relatively high.Clinicians have a tendency to skip a line category in using drugs.Effective measures should be taken to strengthen the management of antibacterials.

To explore the clinical characteristics and imaging features of miliary tuberculomas in central nervous system (CNS).A total of 5 cases diagnosed with tuberculosis in CNS first diagnosed by neurologists in Navy General Hospital of PLA were enrolled in the study.All clinical and imaging data were collected and analyzed retrospectively.The main initial symptoms were fever and headache (4/5).Multiple diffused miliary lesions were shown by brain MRI,with maximum diameter ranged from 1-4 mm and ringshape or nodular enhancement after gadolinium injection.As mycobacterium tuberculosis could seldomly be found in serum and cerebrospinal fluid,contrast MRI remains the effective method for detecting miliary tuberculomas in CNS.
