Many surface proteins of Gram-positive bacteria are anchored to the cell wall by the action of sortase enzymes, a recently discovered family of cysteine transpeptidases. As the surface proteins of pathogens are frequently required for virulence, the sortase might be a suitable target for the development of anti-Gram-positive drugs. Recently, the mechanism and active sites of sortase was elucidated by the research of sortaseA(SrtA) in Staphylococcus aureus and a series of SrtA inhibitors have been identified for providing the basis for further development of potent inhibitors.

The effect of colored noise on circadian oscillation and internal signal stochastic resonance(ISSR) has been studied in a Neurospora circadian clock system. The result shows that the correlation time of colored noise can affect strongly the strength of ISSR. For the case of no external signal(ES), the correlation time of colored noise plays a suppressive role for ISSR, and the suppressive role is increased with the increment of correlation time of colored noise. When the ES is injected to the system, with the increasing of the correlation time of colored noise, not only its suppressive role for ISSR is increased, but also the single peak ISSR can be transformed as internal single stochastic bi-resonance (ISSBR). There exists an optimal frequency of ES for the ISSR information amplification, while the ISSR is suppressed for another frequency of ES. In contrast to external colored noise, internal colored noise is more efficient to sustain and amplify the ISSR information. Furthermore, there exists a critical noise intensity for destroying the difference between white and colored noises.

OBJECTIVE: To summarize the clinical datas of thepatients with invasive laryngeal fungal infections in, discuss pathogenesis and treatment methods. METHOD: Eleven cases of invasive laryngeal fmycosis who were collected from September 2006 to February 2010 with electronic laryngoscopy, aspirate smear and culture and tissue biopsy for pathological diagnosis, were restrospectively analyzed. Those patients were received iv fluconazole, treatment of Oxygen Atomization of amphotericin B solution and taking itraconazole orally. The hepatic and renal functions of the patients were monitored in the course of treatment. RESULT: All the cases were diagnosed of invasive laryngeal mycosis. 1 patient showed liver dysfunction in the second week during treatment. And continuing the treatment after using liver protection drugs. All symptoms of the patients were improved and no recurrence happened during the 1-6 years of follow-up. CONCLUSION Invasive laryngeal fmycosis was correlated with occupation exposure, abusing of antibiotics and low immunity. Laryngeal mycosis was Diagnosised mainly depended on the pathological examination. The positive rates of the secretion smear was low. The effects of iv fluconazole, Oxygen Atomization of amphotericin B 2-4 weeks, and 4 weeks of taking itraconazole orally were safety and reliable.

Objective:To investigate the attentional bias to emotional information in college students with optimistic and pessimistic attributional style.Methods:A total of 83 college students (20 males and 23 females in optimistic group,20 males and 20 females in pessimisticgroup) were recruited online.The 2 cue validity (valid,invalid) × 2 emotional type (positive,negative) × 2 attributional style (optimistic group,pessimistic group) hybrid design was used to investigate the attentional bias to emotional information in college students with optimistic and pessimistic attributional style,adopting the cue-target paradigm.Results:Under valid situation,optimistic group had responded to positive (cue) target faster than pessimistic group [(311.4 ± 26.6) ms vs.(324.1 ±± 47.0) ms,P ＜ 0.05],while there was no significant difference in reaction times (RTs) on negative (cue) target between two groups (P ＞ 0.05).Under invalid situation,optimistic group had responded to negative target faster than pessimistic group [(331.0 ±± 31.7) ms vs.(337.4 ± 50.0) ms,P ＜ 0.05],whereas there was no difference in their RTs to responding to positive target(P ＞ 0.05).Conclusion:It suggests that optimistic individuals and pessimistic individuals respectively have selective attentional bias to positive information and negative information.

OBJECTIVE:To observe the clinical efficacy and safety of enhanced immunosuppressive therapy in the treatment of refractory nephrotic syndrome (RNS). METHODS:Totally 76 RNS patients were selected from 2 hospitals during Jan. 2012-Mar. 2015,and then divided into control group and observation group according to random number table,with 38 cases in each group. Two groups were given Prednisone acetate tablet 50 mg,qd;decreasing to 15 mg,qd,after urine protein returned to normal. Based on it,control group was given Leflunomide tablets 50 mg,qd;decreasing to 20 mg,qd,3 days later. Based on con-trol group,observation group was additionally given Mycophenolate mofetil dispersible tablet 750 mg,bid;decreasing to 500 mg, qd,3 months later. Both groups were treated for 6 months. Clinical efficacies,follow-up recurrence rate as well as renal function in-dexes and inflammatory cell factors before and after treatment,and the occurrence of ADR were compared between 2 groups. RE-SULTS:The total response rate of observation group(92.11%)was significantly higher than control group(73.68%),and fol-low-up recurrence rate(5.26%)was significantly lower than control group(23.68%),with statistical significance(P<0.05). Be-fore treatment,there was no statistical significance in renal function indexes or inflammatory cell factors between 2 groups(P>0.05). After treatment,24 h urinary protein quantification,urinary IL-6 and IL-8 levels of 2 groups decreased significantly,while the content of serum protein increased significantly;the observation group was significantly better than the control group,with sta-tistical significance(P<0.05). There was no statistical significance in the content of serum creatinine between 2 groups before and after treatment(P>0.05). The incidence of ADR in the control group and the observation group was 34.21% and 44.74% respec-tively,without statistical significance between 2 groups(P>0.05). CONCLUSIONS:Enhanced immunosuppressive therapy in the treatment of RNS can improve renal function,reduce inflammatory reaction and long-term recurrence risk,and have good therapeu-tic efficacy and safety.

Objective To report the clinical results of treatment of tarsometatarsal joint injuries by close reduction and percutaneous screw fixation. Methods From January 2003 to June 2005, 26 cases of tarsometatarsal joint injuries were treated with close reduction and percutaneous screw fixation. They were 13 cases of middle column injury, seven cases of medial-middle column injury and six cases of three-column injury according to Myerson’ s classification. Results In this series all the wounds healed primarily with a mean operative time of 40 min ( 30 to 70 min) and a mean incision length of 5 mm. A mean follow-up of 11.4 months (ranging from 6 to 17 months) revealed a mean score of 87 according to American Orthopaedic Foot & Ankle Society (AOFAS) midfoot scoring system. All the patients returned to normal daily life after a mean time of 5.3 months (3 to 11 months). Conclusions Tarsometatarsal joint injuries can be treated well by close reduction and percutaneous screw fixation with less operative lesion and lower incidence of soft tissue complications. Reduction of the middle column with screw insertion along the direction of the Lisfranc ligament is the key to reestablishment of the stability of the tarsometatarsal joint complex.

Obiective To investigate the effect ofisoflurane on expression of IL-1β mRNA,IL-6 mRNA and TNF-α mRNA in the hippocampus of immature rats.Methods sixty-four 7-clay-old SD rats were randomly assigned into 2 groups(n=32 each):control group(group C)and isoflurane group(group S).group S was exposed to 1.5% isoflurane for 6 h while group C to air.Fore animals were killed before anesthesia(T0,baseline),at 2,4,6 h(T1-3)of isoflurane anesthesia and 4,6,12 and 24 h after anesthesia(T4-7).The hippocampi were immediately removed for determimation of the expression of IL-1β mRNA,IL-6 mRNA and TNF-α mRNA by RT-PCR.Results Compared with group C,the expression of IL-1β mRNA at T1-5,IL-6 mRNA at T2.3 and TNF-α mRNA at T1-6 in the hippocampus was upregulated in group S.Conclusion The expression of IL-1β mRNA,IL-6 mRNA and TNF-β mRNA was elevated in the hippocampus of immature rats after being exposed to isoflurane.

Objective To explore the correlation between the carotid atherosclerosis unstable plaque lipoprotein(a) [ Lp(a)]levels with acute cerebral infarction patients.Methods 120 patients with acute cerebral infarction were selected as the research group,and at the same period,120 health cases were selected as the control group.The level of Lp(a) of the two groups was tested,and neck vascular color dopplar ultrasound examination was conducted.Results The incidence of atherosclerotic plaque in carotid artery and unstable plaques was 70.8％,51.7％,respectively,and significantly higher than that of the control group(25.8％,6- 7％ ) ( x2 =5.12,6.43,all P ＜0.05 ).The Lp(a) level of the research group[ (273.6 ± 221.7 )ag/L] was significantly higher than that of the control group[ ( 81.6 ± 64.9) mg/L ] ( t =6.53,P ＜ 0.05 ).Conclusion High level of LP(a) is the independent risk factor of cerebral infarction.The instability of carotid atherosclerotic plaques is the important cause of cerebral infarction.

Objective To analyze the influence of vasoactive drugs on hemodynamics in septic shock patients and to explore the guiding value of systemic vascular resistance index (SVRI) for the application of vasoactive drugs .Methods 21 cases of septic shock in ICU from March 2010 to April 2012 were retrospectively analyzed .The PiCCO monitor technique was applied to monitor the he-modynamic parameters including the cardiac index (CI) ,intrathoracic blood volume index (ITBI) ,systemic cenous resistance index (SVRI) and mean arterial pressure(MAP) ,once per 6-8 h .ITBI>850 mL/m2 was taken as the normal criterion .The data of 202 cases meeting the criterion were collected .These cases were divided into two groups according to whether MAP reach 65 mm Hg , the differences of hemodynamic parameters between the two groups were compared .The MAP≥65 mm Hg group was redivided in-to the group 1 ,2 and 3 according to SVRI .Blood characteristics of pressure ,CI and ITBI were compared among these 3 groups .Re-sults The ITBI value in the MAP<65 mm Hg group and the MAP≥65 mm Hg group was higher than the normal value .The CI and SVRI values in the MAP≥65 mm Hg group were higher than those in the MAP< 65 mm Hg group(P<0 .05) ,while the ITBI value had no difference between the two groups .The ITBI values in the three groups with different SVRI all were higher than the upper normal limit ,furthermore ,in the comparisons among 3 groups ,only comparison between the group 1 and the group 3 had sta-tistical difference(P= 0 .47) .When SVRI was lower ,the CI value was higher than the normal value .Along with the increase of SVRI ,MAP increased gradually ,and CI gradually declined .When SVRI was too high ,MAP had no significant increase ,but the CI value was lower than the lower limit .Conclusion The SVRI monitoring by PiCCO can help to guide the application of vasoactive drugs in septic shock patients ,lower SVRI means the declined vascular reaction and higher SVRI indicates the low cardiac function , moreover blood pressure can not be further enhanced by vascular excessive contraction .
