OBJECTIVE To investigate the uses of antibacterials,the characteristics of bacterial distribution and the drug resistance and provide a foundation for reasonable application of antibacterials.METHODS Germs isolation and cultivation were carried out according to National Clinical Testing Operation Procedures(2nd edition).Germs definition and resistance test were carried out by using VITEK 2 Compact microbiological assay system.Statistical analysis was processed by using WHONET 5.4.RESULTS Totally 7815 strains of bacteria were isolated from clinical samples,most of which were Gram-negatives(G-)(58.0%,56.3% and 59.5%,respectively in the 3 years).The tendency of Gram-positives(G+) didnot charee obviously(about 20%).Theresistance were increasing.The resistance rate of Staphylococcus aureus was more than 70.0 % to the most antibacterials.Up to now,there was no vancomycin-resistant isolate.CONCLUSIONS We should use antibacterials reasonably and efficiently to delay and control drug resistance,according to the susceptibility test.

The growth curve of single cell organisms in batch cultivation could divide into 6 phases, lag phase, acceleration phase, log phase, deceleration phase, stationary phase, and death phase, based on specific growth rate during cultivation process. There were significantly differences between deceleration phase and the other phases in cell growth, substrate consumption, product formation, and genes express profile. The deceleration phase was highly important to fermentation process. However, cognizing and teaching to the deceleration phase had been considerably weakened since a long period. So it should be strengthened.

Objective To study the application value of modified urine nucleoside's detection in prognosis of patients with bladder cancer. Methods We enrolled 85 patients with bladder transitional cell carcinoma confirmed by pathological examination.The 85 patients fulfilled one-year follow-up visit after TUR-BT and were reviewed every three months.The 85 patients did not relapse in the first third month after operation.At the sixth month after operation,20 cases relapsed.18 cases and 19 cases relapsed at the ninth month and the twelfth month after operation.Patients with recurrence added up to 57 cases as the recurrent group.The remaining 28 cases did not relapse at one year after operation as the no recurrent group.Of the 85 cases,55 cases were in T(is) - T1,while 30 cases were in T2 - T4.Of the 85 cases,27 cases were with G1,40 cases were with G2 and 18 cases were with G3.In T(is) -T1,there were 35 cases in recurrent group,while there were 20 cases in the no recurrent group.In T2 -T4,there were 22 cases in recurrent group,while there were 8 cases in the no recurrent group.There were 50 normal people in the control group.Highperformance liquid chromatography/electrospray ionization-quadrupole-time-of-flight mass spectromerry was used to measure the levels of change of two urine modified nucleosides (M1A,1-MeI) which the patients with bladder cancer had different pathology grades,clinical stages,before or after operation and recurrence or no recurrence. Results The levels at third month after operation in no recurrent group ( M1A:3.24 ± 0.40,1 -MeI:5.73 ± 0.67 ) were significantly lower than that before operation ( M 1A:4.34 ± 0.98,1-MeI:14.22 ± 4.05,P ＜ 0.005 ),and remained in low status at another time points after operation.The levels at the third month after operation in recurrent group (M1A:3.31 ±0.33,1-MeI:5.67 ±0.55) were significantly lower than that before operation ( M1A:4.32 ± 1.19,1-MeI:14.31 ± 4.12,P ＜ 0.005 ),which was on the rise and indicating a high level approaching the condition before operation.According to the time point before the operation,recurrent group and no recurrent group were higher than control group (M1A:2.91 ±0.84,1-MeI:5.56 ± 1.25,P ＜ 0.01 ).The levels at the sixth month,ninth month and twelfth month after operation in recurrent group ( M 1A referring to 4.04 ± 0.48,4.11 ± 0.47,4.09 ± 0.53 ;1-MeI referring to1 1.46 ± 1.34,12.14 ± 1.22,12.33 ± 1.27) were the highest (P ＜ 0.01 ).The levels of change of two urine modified nucleosides between pathology grade and clinical stage had no statistical difference ( P ＞ 0.01 ).The levels in recurrence group in T(is) - T1 ( M1 A:5.92 ± 1.28,1-MeI:20.01 ± 8.53 )were higher than the levels in no recurrent group ( M1A:4.02 ±1.22,1 -MeI:11.21 ± 6.45,P ＜ 0.05 ),which was the same in T2 - T4. Conclusion Urine modified nucleosides detection offer a certain clinical value the prognostic of operated bladder cancer patients.

OBJECTIVE:To study the analgesic effect and mechanism of Gutongtie paste on model rats with formaldehyde-in-duced pain. METHODS:60 SD rats were randomly divided into blank group,model group,Gutongtie paste low-dose,medi-um-dose,high-dose groups(0.594,1.188. 2.376 g/paste,containing crude drug 0.48,0.96,1.92 g)and prednisone acetate group (ig,0.0054 g/kg,external bonding matrix). Model rats with pain was induced by formaldehyde method and immediately adminis-trated after modeling. Electronic tenderness instrument was adopted to determine the pain threshold of rats'ankle joint after adminis-tration of 1,2,3,4,6 h. After 6 h,blood sample 0.3 mL was taken from abdominal aorta then rats were sacrificed. Enzyme linked immunosorbent assay (ELISA) was conducted to determine the β-endorphin (β-EP),prostaglandin E2 (PGE2) contents;spectrophotometry was used to determine nitric oxide(NO)content in rats'serum and inflammatory tissue;and radioimmunoassay was adopted to detect the substance P content in rats'serum,inflammatory tissue and brain tissue. RESULTS:Compared with be-fore modeling,pain thresholds in model group at each period were significantly decreased (P<0.05 or P<0.01). Compared with blank group,PGE2,NO of rats,substance P content in inflammatory tissue and brain tissue in model group were significantly in-creased (P<0.05 or P<0.01). Compared with model group,pain thresholds in Gutongtie paste groups at corresponding time points were increased,PGE2 and substance P contents in inflammatory tissue and brain tissue were decreased (P<0.05 or P<0.01);β-EP and NO contents in serum in Gutongtie paste medium-dose,high-dose groups(P<0.05 or P<0.01),NO contents in serum in Gutongtie paste high-dose group were decreased(P<0.05). CONCLUSIONS:Gutongtie paste has a certain analgesic and anti-inflammatory effect,and the mechanism may be related to reducing PGE2, NO, substance P contents, increasing β-EP content.

As one of the major sources of infection, viruses could infect all organisms including bacteria, plants, animals, and humans. Infectious diseases caused by viruses pose a great threat and damage to human health and economic activities all over the world. Adaptor-associated protein kinase 1 (AAK1) is a member of the Ark1/Prk1 family of serine/threonine kinases and a specific key kinase regulating the phosphorylation of AP-2 protein μ2 subunit T156. In the past, AAK1 has been regarded as a feasible biological target for the treatment of nerve pain. Recently, scientists have found that inhibiting AAK1 can regulate endocytosis and inhibit virus invasion into cells. Therefore, AAK1 could be the potential target of anti-virus therapy. This paper reviews the research progress of small molecule AAK1 inhibitors in the field of antiviral, analyzes the future research directions and challenges, and provides new ideas for the development of antiviral drugs targeting AAK1.

Infantile liver failure syndrome type 1 (ILFS1) is a Mendelian disease due to biallelic mutations in the cytoplasmic leucyl-tRNA synthetase gene (LARS). This study aimed to report the clinical and molecular features of the first non-caucasian ILFS1 patient, providing reliable evidences for the definite diagnosis of ILFS1. The 2 years and 9 months old male patient was referred to the hospital with hepatosplenomegaly over 1 year. At age 17 months, he was found to have hepatosplenomegaly and anemia. Since then, he had been managed in different hospitals. The laboratory tests showed liver dysfunction, hypoproteinemia, coagulopathy and anemia, along with histologically-confirmed cirrhosis and fatty liver; however, the etiology remained undetermined. The subsequent SLC25A13 mutation analysis by means of prevalent mutation screening and Sanger sequencing only revealed a paternally-inherited mutation c.1658G>A, and no aberrant SLC25A13 transcripts could be detected from the maternal allele on cDNA cloning analysis, ruling out the possibility of citrin deficiency. Further target exome high-throughout sequencing of genes relevant to genetic liver diseases detected a paternal c.2133_2135del (p.L712del) and a maternal c.1183G>A (p.D395N) mutation in LARS gene. This finding was then confirmed by Sanger sequencing, and ILFS1 was thus definitely diagnosed. The child has been followed up till age 4 years, and his condition became stabilized.
