Journal of Chinese Physician 2012;14(7):907-909
Objective To study the correlation between diabetes and the new discovered angiopietin-related growth factor (AGF)that participates in energy metabolism.MethodsA total of 24 male C.57BL/6 mice were divided into three groups:controlled group; fed with high-fat diet( HFD); fed with high-fat diet for 10 weeks and then treated with rosiglitazone ( HFD + RSG) ; The relative level of AGF mRNA expression in livers was measured by determining a ratio of PCR products of AGF to that of β-actin gene.Oral glucose tolerance test,and insulin resistance index (HOMA-IR) were used to measure blood glucose level and insulin sensitivity.Results Compared with the controls,the expression of AGF mRNA in liver decreased significantly in HFD group( P <0.05),and increased significantly in HFD + RSG group( P<0.01 ).A negative correlation was found between AGF mRNA expression in mice livers and HOMA score ( r =-0.516,P < 0.05 ).Conclusions AGF as a new hepatocyte derived circulating factor counteracts obesity and is related to insulin resistance.

Dopamine(DA) modulates diverse wake-related behaviors including movement,reward, and cognition.Dopaminergic neurons are located in the substantia nigra pars compacta and ventral tegmental area.There are five distinct DA receptors(R):D_1R,D_2R(D_(2S)R and D_(2L)R), D_3R,D_4R and D_5R in the central nervous system, in which D_1R and D_2R are majorly expressed. The affinity of D_2R for endogenous DA is significantly higher than that of D_1R.Re- cently,studies by pharmacological and gene knock-out animals revealed that dopamine D_2R is essential inmaintaining wakefulness.Here,we review the progress on roles of D_2R in sleep-wake regulation.

OBJECTIVE:To investigate the variance of antimicrobial resistance of Klebsiella.spp isolated in our hospital during the recent 5 years.METHODS:Disk diffusion test was used to study the anti microbial resistance.The results were evaluated based on the criteria recommended by American Clinical and Laboratory Standards Institute.The data analysis was performed using WHONET-5software.RESULTS:Atotal of 840 strains of Klebsiella.spp were collected fromour hospital during2003~2007,of which,59.3% were fromrespiratory secretion speci men,12.0%fromblood speci men,and10.1% from secretions.The detection rate of ESBLs-producing Klebsiella.spp was from51.0% to65.1%.No I mipenem-and Meropenem-resistant Klebsiella.spp strain was detected.Susceptibility test showed that Klebsiella.spp-producing ESBLs was multiple resistant,and the anti microbial resistance of Klebsiella.spp has increased year on year.CONCLUSION:Monitoring of the drug resistance of Klebsiella.spp should be strengthened.The variation of the anti microbial resistance of Klebsiella.spp should be noted so as to direct rational drug use in the clinic and prevent spreading of drug resistant strains.

The high incidence of postoperative recurrence of hepatocellular carcinoma ( HCC) is a most difficult obstacle for improving the prognosis of patients.Several adjuvant modalities have been developed to prevent recurrence in patients after surgery; nevertheless , there is no consensus regarding the standardized adjuvant therapy in terms of indications , clinical efficacy and interactions.In this article we review the currently available evidence in the medical literature on adjuvant therapy in HCC after radical resection.

In the research field of quality control in Chinese medicinal materials, variation in active ingredients of medicinal plant is always the key and hot issues. With the development of high-throughput sequencing technologies and reducing cost, a large numbers of genes from medicinal plant were cloning and provide a solid foundation for further research of gene structure and its biological function, and also provides conditions for explore active ingredient variation and its quality control from the perspective of molecular pharmacognosy. This paper introduces the concept of homologous gene, gene duplication and classification. We prospect the function of duplicated genes in the role of molecular mechanism research about variation in active ingredients, aiming at providing a new way for medicinal materials quality control.

Objective To observe the effect of hypertonic saline complex solution (hypertonic saline plus hydroxyethyl starch,HSH) on patients with severe cerebral trauma,high intracranial pressure and shock by the measurement of the changes of the mean arterial pressure (MAP),central venous pressure (CVP) and intracranial pressure (ICP),as well as GOS score changes followed up for 6 months,in order to determine the value of HSH treatment in severe cerebral trauma,intracranial hypertension and shock.Methods Sixty patients with severe brain injury and uncorrected hemorrhagic shock were selected,while the degree of coma was assessed by using GCS score,and shock severity was estimated by using the shock index (SI) score.The patients were randomly divided into HSH group (n =30) and mannitol group (MT group,n =30).Thirty minutes,60 min and 120 min after administration either solution,The changes of MAP,CVP and ICP were observed in two groups,and all patients were followed up for 6 months to observe the outcomes of patients.Results There were no statistically significant differences in age,gender,GCS score,SI scores,and other medication between two groups (P > 0.05),and they were comparable between two groups.After resuscitation of patients in two groups,MAP and CVP were elevated,but the effect of HSH appeared sooner and higher within 30 minutes [MAP (63.1 ± 8.8) mmHg vs.(51.0-9.3) mmHg] (P < 0.05);At the same time,ICP dropped more than 10% lower [ICP (27.3 ± 5.9) mmHg vs.(32.8 ± 4.1) mmHg] (P <0.05),while the effect of MT appeared more slowly in hemodynamic improvement;at 120 min,the increase in MAP and reduction in ICP in HSH group were more significant than those in MT group [MAP (65.9 ± 13.2) mmHg vs.(60.4 ±7.2) mmHg] (P <0.01);the ICP [(22.2 ±4.7) mmHg vs.(28.1 ±6.1) mmHg] (P < 0.01).Followed up for 6 months,good recovery rate in HSH group was higher and poor recovery rate was lower than those in MT group.Conclusions In patients with acute intracranial hypertension and uncorrected hemorrhagic shock,the employment of hypertonic saline plus hydroxyethyl starch solution can produce faster and more effective therapy for shock and reduce intracranial pressure,improving the long-term neurological function of patients.

Objective To study the clinicopathological characteristics and prognosis of asymptomatie IgA nephropathy (IgAN) children with pmteinuria and/or microscope haematuria .Methods Clinical and pathological characteristics of 54 children with IgA nephropathy confirmed by renal biopsy were analyzed . These children with IgAN were divided into two groups according to their clinical characteristics at the first onset: asymptomatic IgAN group (AsIgAN) and symptomatic IgAN group (SIgAN) . Histologic changes were classified by Lee SM and Katafuchi semiquantitative scoring system . Results Eighteen children were in AslgAN group and 36 children were in SIgAN group . The degree of proteinuria in SIgAN group [(2 .3±2 .2) g/d] was higher than that in AslgAN group [(0 .4±0 .3) g/d] at the time of biopsy (P<0 .05) . Although asymptomatic IgAN children were mainly of Lee's type Ⅰ ~Ⅱ, 2 children (11%) were of Lee's type Ⅳ~Ⅴ and 5 cases (27%) presented interstitial injury . Symptomatic IgAN children were mainly of Lee's type Ⅱ ~Ⅲ, there was no significant difference between two groups (P>0 .05) . Urine micrealbumin was increased in 87% children presented with microscope haematuria . After an average of (26 .9±8 .8)months follow-up, only one case of Lee's Ⅴ progressed into renal failure and the others maintained normal renal function . Conclusions Although children with asymptomatic IgAN have minor clinical symptoms, severe renal pathological lesion and poor prognosis also occur . Urine screening helps to detect renal diseases and renal biopsy should be performed in the patients with increased urine microalbumin .
