Objective To explore the efficacy of sequential or combined amphotericin B (AmB) and fluconazole (FCZ) therapy on a 5 flucytosine based regimen in non-acquired immunodeficiency syndrome (AIDS)-related cryptococcal meningitis.Methods A tatal of 117 cases of non-AIDS-related cryptococcal meningitis treated with 5-flurocytosine-based regimens were retrospectively divided into five groups:AmBgroup (n=38),FCZ group (n=25),FCZ and AmB sequential group (n=18),AmB and FCZ sequential group (n=15),AmB and FCZ combination group (n=21).The number in cerebrospinal fluid (CSF) of the five groups were compared.Statistical analyses included t test,oneway analysis of variance,K-independent samples test and chi-square test.Results Intracranial pressure of AmB group,FCZ group,FCZ and AmB sequential group,AmB and FCZ sequential group,AmBandFCZ combination group were (208.6±75.1),(191.5±94.5),(185.0±76.3),(201.9±69.7) and (223.1±89.3) mm H2O (1 mm H2O=0.0098 kPa),respectively,and the differences were not statistically significant (F=0.611,P =0.656).Median cryptococcus counts in CSF of the five groups were 0,10,0,3 and 0/mL,respectively,with no statistical significance (x2 =7.638,P-0.090).CSF protein levels of the five groups were 0.55,0.69,0.67,0.53 and 0.96 g/L,respectively,with no significant differences among groups (F=7.063,P=0.133).The cure rates of the five groups were 55.3% (21/38),32.0% (8/25),9/18,6/15 and 47.6% (10/21),respectively;progression rates or mortality of the five groups were 28.9% (11/38),44.4% (11/25),5/18,4/15and 23.8% (5/21),respectively; and the differences among cure rates (x2 =3.638,P=0.457) and progression rates or mortality (x2-2.785,P =0.604) were not statistically significant.Conclusion FCZ or AmB alone,sequential or combined therapy were all effective in the treatment of cryptococcal meningitis.

ABSTRACT:Objective To validate that relaxin can resist hepatic fibrosis at the cellular level and explore its molecular mechanism in order to provide experimental basis for the treatment of liver cirrhosis.Methods Cultured HSC-T6s were treated with different concentrations (20,50 and 100 ng/mL)of recombinant human relaxin-2 (RLX-2).The proliferation of HSC-T6 was measured by MTT colorimetric assay.The content of type Ⅰcollagen in the cell culture supernatant of each group was detected by ELISA at 48 h of drug intervention;RT-PCR was used to detect the mRNA expressions of CTGF and TGF-β1 in HSC-T6 at 48 h of drug intervention.Results RLX-2 inhibited the proliferation of HSC and reduced type Ⅰ collagen content of HSC cells.It also inhibited the CTGF mRNA expression of HSC,but did not have a significant effect on the expression of TGF-β1 mRNA. Conclusion In the experiment of culturing HSC-T6 in vitro,RLX-2 may play a role in rat liver fibrosis by inhibiting cell proliferation and type Ⅰ collagen and CTGF mRNA expressions.

Objectives: The survivors of first-ever stroke are at a high risk of recurrent stroke. The time interval
between first-ever stroke and first recurrence of stroke, however, have not been well studied. The aim
of the present study was to evaluate the time interval between first-ever and first recurrence of stroke
and the risk factors of stroke that were related to the length of time interval. Methods: Patients admitted
in our hospitals during 2014 with first recurrence of stroke were included in the study. A total of 377
patients were enrolled and a standardized questionnaire was used to collect data in this retrospective
study. Results: The mean time interval among all the subjects was 58.42 months (median, 36.01 months;
range 0.16months to 455.98months). The mean time interval was shorter in hemorrhagic stroke group
(56.78 months) than in ischemic stroke group (58.75 months), but the difference was not significant
(p=0.819). The median of time interval was similar in the two groups. The associated risk factors to
the length of time interval were age over 60 years, subtype of first-ever stroke, the length of history
of hypertension. Age was the only associated risk factor to the time interval among patients with first
recurrence of hemorrhagic stroke.
Conclusion: Factors associated with the time interval are different among different types of recurrent
stroke. This provides the basis for preventive treatment for recurrent stroke after their first-ever stroke

OBJECTIVETo investigate the main factors that influence the results of sperm alkaline single-cell gel electrophoresis (SCGE), optimize the conditions, and standardize its procedures.
METHODSUsing alkaline SCGE, we detected the DNA fragments of sperm treated with different concentrations of H2O2 and determined the influences of the number of agarose gel layers, pH during DNA unwinding and electrophoresis, the time of DNA unwinding and electrophoresis, and cumulative sperm number on the results of sperm alkaline SCGE. Then we optimized the procedures, analyzed the repeatability of the optimized method, and examined 40 semen samples using the method.
RESULTSThree agarose gel layers could reduce the background. The optimal pH during DNA unwinding and electrophoresis was 10, and the best times for DNA unwinding and electrophoresis were 40 min and 30 min, respectively. Fifty sperm were adequate to ensure the reliability of the results. Based on the percentage of tail DNA, the intra- and inter-assay repeatabilities of the optimized sperm alkaline SCGE were 3.12% and 7.13%, and by the DNA damage score, they were 2.38% and 6.09%, respectively. Sperm DNA fragments were significantly increased in the infertile patients with oligoasthenoteratozoospermia as compared with healthy fertile males (P <0.05).
CONCLUSIONThe optimized sperm alkaline SCGE, highly repeatable and easy to be standardized, can be applied to the clinical detection of sperm DNA fragmentation in infertile men.
