OBJECTIVETo study the effect of Acanthopanax senticosus injection (ASI) on the activities of human tumor necrosis factor (TNF) and natural killer cell (NKC) in the patients with lung cancer and the underlying mechanism.

METHOD73 cases with lung cancer were randomly divided into two groups, namely, the treatment group (n = 39) and observation group (n = 34); 61 cases with or without other diseases were respectively divided into control A (n = 30) and B (n = 31) groups. The patients in treatment group were injected with ASI for 21 days. The activities of human TNF and NKC and the levels of IgG, IgA and IgM were detected respectively.

RESULTAfter injection with ASI the activity of TNF-alpha in treatment group was comparable with that in the two control groups and was significant lower that that in observation group. The activity of TNF-beta and the levels of IgA, IgG and IgM were significantly higher than those in observation group and two control groups (P < 0.01). The activity of NKC was also remarkably higher than observation and two control groups.

CONCLUSIONASI can regulate the cellular immunity and factor, indicating that ASI can be used as an assistant drug to regulate the function of cellular immunity in the patients with lung cancer.

The safety of Chinese patent medicine has become a focus of social. It is necessary to carry out work on post-marketing clinical safety evaluation for Chinese patent medicine. However, there have no criterions to guide the related research, it is urgent to set up a model and method to guide the practice for related research. According to a series of clinical research, we put forward some views, which contained clear and definite the objective and content of clinical safety evaluation, the work flow should be determined, make a list of items for safety evaluation project, and put forward the three level classification of risk control. We set up a model of post-marketing clinical safety evaluation for Chinese patent medicine. Based this model, the list of items can be used for ranking medicine risks, and then take steps for different risks, aims to lower the app:ds:risksrisk level. At last, the medicine can be managed by five steps in sequence. The five steps are, collect risk signal, risk recognition, risk assessment, risk management, and aftereffect assessment. We hope to provide new ideas for the future research.

OBJECTIVETo assess the effects of seawater immersion of open abdominal wound and drowning on plasma electrolyte levels in dogs.

METHODSTwenty-one dogs with open abdominal wounds were randomly divided into 3 groups, namely the control group (n=7), seawater immersion group (n=7) and seawater immersion and drowning group (n=7). The dogs in the control group were subjected to simple open abdominal wound, and those in the latter two groups were immersed into seawater after the abdominal injury. The changes in the plasma electrolytes and osmotic pressure were observed after the treatments. RESULTS AMD CONCLUSION: Seawater immersion of the open abdominal wound results in hypematremia, hyperkalemia and hypertonic dehydration, and the effect is proportional to the length of immersion time, but seawater airway perfusion does not cause obvious changes of the plasma electrolytes and osmotic pressure in dogs.

OBJECTIVETo explore the abnormal expression of plasma proteins by analysis of proteomic expression profile in children with infectious mononucleosis (IM).

METHODSTwo dimensional gel electrophoresis (2-DE) followed by the mass spectrometry was used to examine important protein spots with different expression levels between children with IM and normal controls.

RESULTSSeven differential proteins were obtained: hemopexin, vitamin D binding protein, fetuin A, C-reactive protein, apolipoprotein A, haptoglobin and transthyretin. Compared with the control group, haptoglobin showed a higher expression level in children with IM, and the expression levels of the other proteins were obviously down-regulated.

CONCLUSIONSThe expression changes of differential proteins identified in this study are all related with the liver acute injury, suggesting that children with IM are associated with acute liver injury. Further studies on the characteristics of above proteins will contribute to the diagnosis and treatment of pediatric IM.

Objective To observe the effects of acupuncture on TLR4, inflammation factors IL-1β and IL-6 expressions in the prefrontal cortex of vascular dementia (VD) rats; To investigate the brain protective mechanisms of acupuncture. Methods A total of 50 rats were randomly divided into sham-operation group, model group, acupuncture group, and placebo-acupuncture group. The animal model of VD was replicated by permanent bilateral common carotid artery occlusion (2VO) in rats. Acupuncture was performed at three days after surgery, once daily for two weeks. Morris water maze was used to test the cognitive function. The expressions of Iba1 and TLR4 were assessed by immunohistochemical method. Inflammation factors IL-1β and IL-6 mRNA expressions were tested by RT-PCR. Results Compared with sham-operation group, the model group rats showed impaired spatial learning and memory ability, and expression of Iba1, TLR4, and IL-1β, IL-6 increased. Compared with the model group, the spatial learning and memory abilities of the acupuncture group were improved, and the expression of Iba1, TLR4 and IL-1β, IL-6 in the prefrontal cortex decreased. These effects were not found in the placebo-acupuncture group. Conclusion The effect of acupuncture may be achieved by inhibiting microglia activate, decreasing the expressions of TLR4, IL-1β and IL-6 in the prefrontal cortex, resulting in improving spatial learning and memory ability of VD rats.

BACKGROUNDInfants in some areas of China developed urinary lithiasis after being fed with powdered milk that was tainted with melamine in 2008 and very small proportion of the infants developed acute renal failure caused by urinary tract calculus obstruction. The aim of this article was to summarize clinical characteristics, diagnosis and treatment of infants with urinary calculus and acute renal failure developed after being fed with melamine tainted formula milk.

METHODSData of infant patients with urinary calculus and acute renal failure due to melamine tainted formula milk admitted to the Beijing Children's Hospital Affiliated to the Capital Medical University and the Xuzhou Children's Hospital in 2008 were used to analyze the epidemiological characteristics, clinical manifestations, imaging features as well as effects of 4 types of therapies.

RESULTSAll the 34 infants with urinary calculus were complicated with acute renal failure, their blood urea nitrogen (BUN) was (24.1+/-8.2) mmol/L and creatinine (Cr) was (384.2+/-201.2) micromol/L. The chemical analysis on the urinary calculus sampled from 15 of the infants showed that the calculus contained melamine and acidum uricum. The time needed for the four types of therapies for returning Cr to normal was (3.5+/-1.9) days for cystoscopy group, (2.7+/-1.1) days for lithotomy group, (3.8+/-2.3) days for dialysis group, and (2.7+/-1.6) days for medical treatment group, which had no statistically significant difference (P=0.508). Renal failure of all the 34 infants was relieved within 1 to 7 days, averaging (3.00+/-1.78) days.

CONCLUSIONSMelamine tainted formula milk may cause urinary calculus and obstructive acute renal failure. It is suggested that firstly the patients with urinary calculus complicated with acute renal failure should be treated with dialysis or medication to correct electrolyte disturbance, in particular hyperkalemia, and then relieve the obstruction with available medical and surgical methods as soon as possible. It was observed that the short-term prognosis was satisfactory.

To explore the resource components and availability of different parts of Panax quinquefolium in Shandong province, the paper employed the non-targeted metabolomics technology based on ultra-high performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS) to analyze the metabolites and their metabolic pathways in the root, fibril, stem, and leaf of P. quinquefolium. The content of seven ginsenosides and polysaccharides in different parts was determined by high performance liquid chromatography(HPLC) and ultraviolet-visible spectrophotometry(UV-Vis). The results showed that the metabolites were mainly sugars, glycosides, organic acids, amino acids and their derivatives, terpenoids, etc. The total abundance of metabolites followed the trend of leaf > root > fibril > stem. Most of the differential metabolites were concentrated in phenylpropane biosynthesis, flavonoid biosynthesis, citric acid cycle, and amino acid biosynthesis. The leaf contained high levels of sugars, glycosides, amino acids and their derivatives, and flavonoids; the root was rich in terpenoids, volatile oils, vitamins, and lignin; the fibril contained rich organic acids; and the stem had high content of nucleotides and their derivatives. The content of ginsenosides Re and Rb_1 was significantly higher in the root; the content of ginsenosides Rg_1, Rg_2, Rd, F_(11), and polysaccharide was significantly higher in the leaf; and the content of ginsenoside Rb_2 was significantly higher in the stem. We analyzed the resource components and availability of different parts of P. quinquefolium, aiming to provide basic information for the comprehensive development and utilization of P. quinquefolium resources in Shandong province.

In this study, the colonization, diversity and relative abundance of arbuscular mycorrhizal fungi(AMF) in the roots of Panax quinquefolius in different habitats of Shandong province were analyzed by staining-microscopy and high-throughput sequencing. The data were analyzed by bioinformatics tools and statistical software. The results showed that the roots of P. quinquefolius in different habitats were colonized by AMF with different rates and intensities. The AMF in roots of P. quinquefolius belong to three genera, three families, three orders, one class and one phylum. At the level of order, the AMF mainly included Paraglomerales(52.48%), Glomerales(25.60%) and Archaeosporales(3.08%). At the level of family, the AMF were dominated by Paraglomeraceae(52.48%), Glomeraceae(18.94%) and Claroideoglomeraceae(3.05%). At the level of genus, Paraglomus(51.46%), Glomus(20.01%) and Claroideoglomus(3.52%) accounted for a large proportion, of which Paraglomus and Glomus were dominant. Cluster analysis showed that the AMF in roots of P. quinquefolius with close geographical locations could be clustered together. In this study, the diversity and dominant germplasm resources of AMF in roots of P. quinquefolius cultivated in the main producing areas were identified, which provi-ded basic data for revealing the quality formation mechanism of P. quinquefolius medicinal materials from the perspective of environment.
