Acta Pharmaceutica Sinica 2015;50(1):111-117
The transplants of one-year-old Glycyrrhiza uralensis Fisch. were subjected to five concentrations of MnSO4-H2O (0, 1.81, 18.1, 36.2 and 54.3 mg·L(-1)) culturing in vermiculite. qRT-PCR and HPLC were respectively used to measure the relative expression of SQS1 gene and the content of glycyrrhizic acid of G. uralensis in different concentrations of MnSO4·H2O. This is to explore discuss the effects of the expression of SQS1 gene and the accumulation of glycyrrhizic acid by Mn treatment. The results showed both the expression of SQS1 gene and the content of glycyrrhzic acid of G. uralensis tended to rise after the fall of the first with the increase of concentration of Mn treatment. And they were of very significant positive correlation (P<0.01, r=0.737). Relative expression of SQS1 gene reached the highest 7.90 under 18.1 mg·L(-1) MnSO4·H2O treatment. It was very significantly different between 18.1 mg·L(-1) concentration of MnSO4·H2O treatment and CK (0 mg·L(-1)), 1.81, 36.2 and 54.3 mg·L(-1) (P<0.01), and 1.75, 1.37, 1.37, 2.33 times respectively. The content of glycyrrhizic acid reached the highest under 1.81 and 18.1 mg·L(-1) MnSO4·H2O treatment, and there were not significant difference (P>0.05). It was very significantly different between them and other concentrations of MnSO4·H2O treatment (P<0.01). This study suggests the appropriate concentration of Mn treatment could certain promote the expression of SQS1 gene and the accumulation of glycyrrhizic acid of G. uralensis.

Lung cancer is one of the commonest of malignant tumor in the world.It is a major threat to human health in China with highest morbidity and mortality.Steady increase in incidence rates have been observed worldwide in the last few decades in young patients,but previous studies have provided conflicting data about the clinical characteristics and prognoses of young patients with lung cancer.Consequently,we have difficulty in comparing their results with each other,as the cutoff ages defining"young"were different in each study.Therefore,this article focuses on the clinical characteristics and the different results of researches for the young patients with primary lung cancer.
5.Advances in Laboratory Diagnosis of Avian Influenza Virus
Microbiology 1992;0(05):-
Avian influenza viruses (AIV) can cause serious economic losses and threaten to human health. The laboratory methods for rapid and accurate detecting AIV ensure timely implementation of intervention strategies so that it plays a key role in avian influenza prevention and control. The laboratory technologies for detecting AIV are topic subject and developed quickly those days. This paper reviews the advances of laboratory diagnosis technologies for AIV at 3 aspects of virus isolation, immunoassay and molecular diagnostics.

Objective:The study was designed to observe the change of intestinal permeability and its relationship with serum proteins in patient with pancreatic cancer. Methods: A prospective and controlled trial was taken. 15 patients with pancreatic cancer were chosen as experimental group. 15 healthy volunteers were as control group. Urine lactulose/mannito(L/M) ratio, serum concentration of TNF-? and serum levels of albumin(ALB), transferritin (TF) and prealbumin (PA) were measured. Results: The urine L/M ratio was significantly increased in experimental group compared with control group(0.331 vs 0.129, P

Objective To study the clinical features of invasive pneumococcus disease (IPD) with resistance to antimicrobial agents in children,and to improve the diagnosis and treatment of this disease.Methods The clinical data from 21 IPD patients younger than 13 years old were collected from January 2008 through December 2010 in Pediatric Intensive Care Unit in Beijing Children's Hospital for retrospective analysis. Specimens of blood,pleural effusion,cerebrospinal fluid and soft tissue aspirated were collected from these children,and 23 strains of streptococcus pneumonia (SP) were cultured,isolated and confirmed,and the antibiotics susceptibility to penicillin and other antibiotics of these strains were assayed.Results Among the 21 IPD children,the ratio of male to female was 0.9∶1,and the age was 5 months to 13 years,with 61.9% of them under 2 years.Of them,12 patients (57.1% ) had purulent pleurisy,and 1 (4.8% )patient had an underlying disease diagnosed to be X - linked agammaglobulinemia (XLA).There was no seasonal difference in the occurrence rate of this disease. Eight (38.1%) patients were cured,11(52.4% ) were improved,while 2 (9.5% ) patients not improved without death.There was no statistically significant difference in the annual detection rate of invasive SP (x2 =3.711,P =0.156).The incidences of penicillin-intermediate susceptibility SP (PISP) and penicillin-resistant SP (PRSP) were 47.8% and 26.1% respectively.The rate of resistance to multiple antibiotics was 91.3%.Conclusions Children aged less than 5 years,especially younger than 2 years,are prone to IPD,and purulent pleurisy and septicemia are often seen in this disease. Some patients had the underlying diseases.The complications included hemophagocytic syndrome,acute respiratory distress syndrome,septic shock,bronchial pleural fistula and so on.The multidrug resistance rate was 91.3%.It is important to put great emphasis on the monitoring antibiotics resistance to invasive pneumococcal disease.
