Journal of Modern Laboratory Medicine 2017;32(4):140-142
Objective To determine the genotypes of human papillomavirus (HPV) and to estimate their recurrence of condyloma acuminatum (CA) among female in Xi'an.Methods HPV genotype was detected with human papilloma virus genotyping kit in 63 female patients with CA.Follow-up was carried out to observe the recurrence of CA in these patients after CO2 laser treatment.Results Of the 63 specimens,61 (96.83%) were positive for HPV,and a total of 16 HPV subtypes were identified.The predominant genotypes were HPV6 (59.2%),11 (22.95%),42 (8.20%),43 (8.20%),52 (8.20%),16 (6.56%) and 18 (4.92%) respectively.43 cases of single HPV infection was accounted for 70.49% (43/61),mixed infection in 14 cases was accounted 22.95 % (14/61).61 cases of patients with laser treatment,observing the recurrence of cuses after 3-month later,it was found that the recurrence rate in higher risk group and mixed infection group was higher than that in low-risk group.Conclusion HPV6,11 is main HPV infection type of the female patients in Xi'an,the recurrence of CA is higher in patients with high risk HPV than in those with low risk HPV and mixted infection.Mixted infection of HPV and high risk HPV is a risk factor for recurrence of female genital warts in Xi'an region.

[Summary] SIRT3 is a member of the silent information regulator 2 ( Sir2) family, located in the inner mitochondrial membrane, with a strong effect of deacetylation. SIRT3 not only modulates energy metabolism, cell apoptosis, tumor growth, anti-aging etc. , but also plays an important role in the field of cardiovascular diseases. In this review, we summarize recent findings related to SIRT3 with metabolic syndrome and cardiac hypertrophy, to provide a theoretical basis for the further study on the potential role of SIRT3 in cardiovascular diseases.

To express feruloyl esterase A from Aspergillus oryzae in Pichia pastoris expression system and study its hydrolysis function, explore the conditions and effects of purification for ferulic acid extracts by macroporos resin. Using the total RNA from A. oryzae CICC 40186 as the template, we amplified coding sequence AorfaeA encoding a mature feruloyl esterase A (AorFaeA) by RT-PCR technique. Then, the coding sequence AorfaeA was successfully expressed in Pichia pastoris GS115 mediated by an expression plasmid pPIC9K. The purified recombinant AorFaeA (reAorFaeA) showed one single band on SDS-PAGE with an apparent molecular weight of 39.0 kDa. The maximum activity of reAorFaeA to methyl ferulate, measured by high-performance liquid chromatography (HPLC), was 58.35 U/mg. Then, reAorFaeA was used to release ferulic acid from de-starched wheat bran in the presence of xylanase. The purification tests for ferulic acid from the enzymatic hydrolysate were carried out with preselected macroporous resins. The results showed that macroporous resin HPD-300 had much higher adsorption and desorption capacities. Ferulic acid could be quantitatively recovered by 50% of the eluent concentration at a flow speed of 1 mL/min. Under the purification condition, the recovery ratio of ferulic acid was 92%, and the content of ferulic acid was increased from 0.13% in the raw material to 10.55%. This work exploits the breakdown of ferulic acid by recombinant enzymeand provids a good strategy to its "green production".

Objective To determine the efficacy of lifestyle interventions in adults with impaired glucose tolerance (IGT).Methods MEDLINE (Pub Med),EMBASE,Science Citation Index (SCI),and Cochrane Database were retrieved for articles about the relations of lifestyle intervention and IGT.Searches were limited to English language publications.The RCTs outcome evaluated in this study included 2 h plasma glucose level and fasting plasma glucose,meta-analysis was carried oat by Stata 11.0 among articles for the inclusion and exclusion criteria.The difference of effects was expressed as standardized mean deviation(SMD).Results A total of 10 RCTs studies met the inclusion criteria.Lifestyle interventions were associated with a decline in 2 h plasma glucose and fasting plasma glucose level (SMD =-0.67,P<0.01 ;SMD =-0.33,P<0.01),but high heterogeneity was identified in this meta-analysis.Conclusion Physical,dietary and both combined interventions can reduce 2-h plasma glucose and fasting plasma glucose levels in adults with impaired glucose tolerance.As high heterogeneity was identified in this meta-analysis,more high quality research is needed.
