Methylotrophy is a kind of widespread microbe which can use carbon compound as their only carbon and energy sources.It has been reported that methylotrophy can directly use one carbon com-pound to transform into their own metabolic one carbon unit,then these one metabolic one carbon units can be used as energy and carbon skeleton by organisms,which is a main part in one carbon metabolism.Because this is a novel metabolic system,it can be used in the study of biological metabolism and evo-lution.Based on the previous study about Methylobacterium sp.MB200 in our lab,here we summarized the research improvements about methylotrophy from their taxonomy,metabolism,genomics and ap-plications.

AIM: To evaluate the efficacy and complications of intravitreal injection of triamcinolone acetonide ( TA ) for the treatment of macular edema caused by pre-retinal membrane of the macular.
METHODS: Totally 23 patients ( 24 eyes ) with macular edema caused by pre-retinal membrane of the macular were treated withintravitreal injection of 4mg TA. Best-corrected visual acuity ( BCVA ) , intraocular pressure ( IOP ) , slit - lamp examination, fundus fluorescein angiography ( FFA ) and optical coherence tomography (OCT) were performed before and after treatment. The SPSS 12. 0 software was used for statistical analysis.
RESULTS: After 10, 30, 90d of treatment of TA, as compared with before treatment, visual acuity improved significantly ( P<0. 05 ), and central macular thickness (CMT) was significantly thinner (P<0. 01). The average central macular thickness decreased from 522 ± 126μm before treatment to 264±115μm, 245±128μm, 286±131μm at 10, 30, 90d after treatment. Macular edema reduced. IOP increased in 7 eyes ( 29%) , one cataract case, no other complications associated with vitreous injection.
CONCLUSION: Intravitreal injection of TA in the treatment of macular edema caused by pre - retinal membrane of the macular is simple, safe and easy to operate. It can quickly reduce macular edema, and improve the visual acuity in the short term. Part of patients may recur after injection in the first half of the year.

Salvia miltorrhiza Bge. is a perennial deciduous flowering plant. Its medicinal root and rhizomes part is widely used in the treatment of various diseases. In this study, bioinformatics analysis was performed to identify 4832 genome SSR loci with length longer than or equal to 40 bp from the draft genome assembly of S. miltorrhiza. The re-sults showed that the dinucleotide repeat motifs and trinucleotide repeat motifs constitute the main types of genome SSR loci, accounting for 37.3% and 61.3% respectively. SSR types enriched with A/T bases showed significantly higher abundance than other types, including AT/TA AAT/ATT, ATA/TAT, TAA/TTA, accounting for 30.5%, 21.6%, 17.1%, 20.4% of the total number of SSR loci, respectively. 1079 primer pairs were designed for these genome SSR loci. These primers can be used for genomic diversity analysis, genetic map construction, genetic marker screening. These data could lay the foundation for population genetics and genomics research of S. miltorrhiza.

Objective To observe the effects of nebulized nitric oxide donors on pulmonary and systemic hemodynamics during pulmonary hypertension induced by hypoxia (FiO_2=0.1,for 1 hour)in newborn piglets. Methods Twenty-four anesthetized and mechanically ventilated piglets were randomly divided into four groups:(1)group S (n=6),control group;(2)group C (n=6),receiving saline after hypoxia;(3)group NTG,receiving nebulized nitroglycerin after hypoxia;(4)group SNP,receiving nebulized sodium nitroprusside after hypoxia. Mean arterial pressure (MAP)and mean pulmonary arterial pressure (MPAP)were monitored continuously. Arterial blood gas analysis was determined at baseline,1 hour after hypoxia,termination of nebulization and 0.5 h after nebulization. After nebulization,blood methemoglobin (MetHb)and plasma NO level were measured.Results Acute hypoxia resulted in a significant increase in MPAP. At 1 hour after hypoxia,MPAP in group C,group NTG and group SNP were significantly higher than that in group S(P0.05).After nebulization,there were no significant differences in plasma NO level and blood MetHb level between groups. No rebound pulmonary hypertension was observed after withdrawal of nebulization. Conclusion Both NTG and SNP nebulization could be used as selective pulmonary vasodilators for acute hypoxic pulmonary hypertension.

Objective To investigate and compare the clinical effects of 2-micron laser vaporization resection of prostate (2-micron laser) and versus transurethral resection of prostate (TURP) for treatment of benign prostatic hyperplasia(BPH) in this prospective random control study.Methods Sixty patients of BPH were randomly divided into two groups including the 2-micron laser group (n =30) and the TURP group (n =30).The perioperative markers and therapeutic results including duration of surgery,blood lose during surgery,improvement of symptoms after treatment,postoperative bladder washing time,the mean bladder irrigating time,hospital stay time,and recent complications were recorded and analyzed.Results The international prostate symptom score((6.6 ± 1.8) vs.(33.2 ±2.2),(5.7 ± 1.3) vs.(33.4 ±2.3) respectively),maximal urinary flow((20.6 ± 1.5) ml/s vs.(7.8 ± 4.3) m/s,(19.5 ± 1.7) ml/s vs.(8.3 ± 4.5) ml/s respectively),residual urine volume((22.3 ±4.7) ml vs.(57.2 ± 10.5) ml,(26.3 ±7.2) ml vs.(60.2 ± 14.5) ml respectively) were significantly improved in both groups after operation (P =0.005,0.008,0.036,0.001,0.005,0.013 respectively),but the differences between these two groups were not significant (P =0.16,0.49,0.97 respectively).The volume of hemorrhage ((20.9 ± 12.1) ml vs.(55.3 ± 27.8) ml),the mean bladder irrigating time ((1.0 ±0.5) d vs.(3.5 ±0.7) d),cathererization time ((3.2 ± 1.3) d vs.(6.0 ± 1.5) d),hospital stay time ((6.8 ±0.7) d vs.(10.6 ±0.6) d) were significantly less or shorter in the 2-micron laser group than in the TURP group (P =0.009,0.005,0.035,0.03 respectively).There was no significant difference in rates of complications between the two groups (P ＞ 0.05).Conclusion The therapy of 2-micron laser is safer and more efficacious than TURP for BPH patients,with advantages of short surgery duration,little blood loss,and quick recovery.

Objective To investigate the current status of multidrug-resistant organism (MDRO) infection in the general surgery department of a tertiary first-class hospital, and understand the efficacy of comprehensive intervention measures.Methods Targeted monitoring on MDROs was implemented among patients who were hospitalized in a general surgery department for>48 hours between March 2015 and October 2016, comprehensive intervention measures were taken since January 2016.MDRO infection before and after intervention was compared.Results Between March 2015 and October 2016, a total of 6 406 hospitalized patients were monitored, 155(2.42%) developed MDRO infection.The most common infection sites were abdominal cavity(hydrops, bile) (n=76, 49.03%) and surgical site (n=43, 27.74%).MDRO infection rate dropped from 2.79% (99/3 549) before intervention (March-December, 2015) to 1.96% (56/2 857) after intervention (January-October, 2016) (x2=4.612, P=0.032).There was no difference in MDROs between before and after intervention, the major were both Escherichia coli.Conclusion Comprehensive intervention measures can reduce the incidence of MDRO infection in the general surgery department of this hospital.

ObjectiveTo evaluate the quantitative and qualitative changes of peripheral-type benzodiazepine recepors (PBRs) in brain mitochodria and in platelet membrane in aging rats. MethodsMale Sprague-Dawley rats were divided into 3- and 24-month groups. All animals were sacrificed by decapitation and the brains were immediately removed. Mitochondrial components from dissected cerebral cortex were isolated. The membrane of platelets from venous blood was prepared by the method of hypotonic hemolysis. The specific binding assay of the radioactive PBRs antagonist ［3H］PK11195 to membrane was performed. Scatchard analysis was performed to estimate the equilibrium dissociation constant (Kd) and the maximal binding site density (Bmax). ResultsA significant increase in ［3H］PK11195 binding activity in the mitochodria from cerebral cortex in 24-month rats was observed compared to that in 3-month rats(P<0-001). Meanwhile, the Scatchard analysis revealed that there was an increase in Bmax, with a significant increase in Kd in 24-month rats. The same change of ［3H］PK11195 binding activity was noted for platelet membrane in 24-month rats(P<0-001).ConclusionThe density of PBRs increases in cortex mitochondria in aging rats, but the binding affinity of PBRs decreases which may be attributable to the progressive pathogenesis of aging in rats. ［3H］ PK11195 binding activity of platelet membrane might reflect the change of PBRs in the brain tissue.
