Objective To investigate the change of immunologic function of red blood cell (RBC) in patients with chronic gastritis. Methods The immunologic function of RBC in 88 cases of chronic gastritis was dynamically detected with yeast rosette method. Results The results showed that RBC-C3b receptor rosette (RBC-C3b-RR) rate and RBC immune adherence enhance factor (RFER) rate were significantly lower (P＜0.05) and RBC immune complex rosette (RBC-ICR) rate and RBC immune adherence inhibitor factor (RFIR) were significantly higher (P＜0.05) in the patients with atrophic gastritis than those in control group. In the patients with superficial gastritis, the difference had no distinct significance (P＞0.05). Conclusion The immunologic function of red blood cell (RBC)measurement plays an important role in differential diagnosis and prognosis evaluation of chronic gastritis.

Taking eugenics,family planning and reproductive human-assisted projects for instance,the article discusses the conflicts between modern biotechnology and the contemporary ethics.It distinguishes the concepts of life quality and that of health,and advocates that the modern medicine should conduct to be in pursuit of the high quality of life.Finally,it puts forward that we should upgrade the quality of individual's life in the circumstance of a stable and integrated communal ethics.Biotechnology may be developed immeasurably,but should be used restricted and morally.

Objective To investigate the role of cytokines genes expression of liver sinusoidal endothelial cells in liver damage by sepsis.Methods Septic mice models were established with cecal ligation and perforation (CLP), while sham operation group received the same procedure exclusive CLP. The genes expression of TNF?, IL 1? and IL 6 in liver sinusoidal endothelial cells were assessed by RT PCR. Results A significant increase of TNF?, IL 1? genes expression was observed at 3h, and a slight decline at 12h after operation, but still significantly higher than that in the sham group; while IL 6 gene expression showed signficantly higher at 3h and remained at the high level at 12h. Conclusions Liver sinusoidal endothelial cell is an important source of cytokine production in mice with sepsis.

Objective To discuss the relationships between serum uric acid levels and clinical stages,cognitive dysfunction in parkinson' s disease (PD).Methods Sixty patients of PD were enrolled,and their history,detailed physical examination UPDRS Ⅲ scale and mini-mental state score (MMSE) scale were performed to determine the Hoehn-Yahr stage of patients.At the same time 52 cases of healthy person were collected from the Health Examination Centers whose age,sex,and education matched with PD group as control group.The levels of serum uric acid in the two groups were examined and compared.Results The serum uric acid levels in PD group were significantly lower than those in normal control group((262.4 ±85.2) μmol/L vs (357.6 ±73.3) μmol/L) (t =1.013,P =0.005) ;There was no level correlation between different Hoehn-Yahr stage period of PD group (r =0.143,P ＞ 0.05) ; There was no significant difference on serum uric acid levels between subgroup of PD patients (F =1.014,P =0.06) ;The M MSE score between PD group and normal control group had no significant difference (26.12 ± 2.87 vs 28.32 ± 2.17) (t =1.970,P =0.073).Conclusion Low level of the serum uric is likely to be a risk factor for PD,but cannot be used to assess the severity of disease and MMSE scale used to determine the cognitive impairment in PD is not sensitive enough.

OBJECTIVETo study the gene expression of adhesion molecules in pulmonary and hepatic microvascular endothelial cells during sepsis in mice.

METHODSMale mice were subjected to cecal ligation and puncture (CLP) and microvascular endothelial cells in pulmonary and hepatic tissues were harvested at 3 hours (early sepsis) and 12 hours (late sepsis) after CLP, respectively. Gene expression of the adhesion molecules was assessed by reverse transcription polymerase chain reaction (RT-PCR). Simultaneously, the alterations of myeloperoxidase (MPO) activity in pulmonary and hepatic tissues were also examined.

RESULTSE-selectin mRNA levels markedly increased at 3 hours after CLP in both pulmonary and hepatic microvascular endothelial cells, then they returned to the normal level at 12 hours after CLP. Increases in intercellular adhesion molecule-1 (ICAM-1) mRNA levels were found at 3 hours after CLP in both pulmonary and hepatic microvascular endothelial cells, and these levels became higher at 12 hours after CLP. Adhesion molecule-1 (VCAM-1) mRNA expression of vascular cells also increased significantly at 3 hours and 12 hours after CLP in both pulmonary and hepatic microvascular endothelial cells. The level of VCAM-1 mRNA in hepatic microvascular endothelial cells was higher at 3 hours than that at 12 hours after CLP, while the level of VCAM-1 mRNA in pulmonary microvascular endothelial cells was higher at 12 hours than that at 3 hours after CLP. The MPO activity in pulmonary and hepatic tissues increased at 3 hours after CLP, compared with that of the sham group. They both declined significantly at 12 hours after CLP, but they were still higher than that of the sham group.

CONCLUSIONSThe up-regulation of the gene expression of adhesion molecules in pulmonary and hepatic microvascular endothelial cells is an important step for the migration and accumulation of leukocytes at the site of inflammation, which plays a critical role in organ damage during sepsis. And the contribution of the heterogeneity of endothelial cells in organs' vulnerability during sepsis is worth a further investigation.

Lymph metastasis has great impact on the prognosis of pancreatic cancer patients, which can relfect the biological and invasive potential of pancreatic cancer. However, currently, there is no standard in the clinical management of the lymph metastasis in pancreatic cancer. In this report, we will discuss and summarize the followings:lymph metastatic rate and its impact on prognosis, the rule of lymph metastasis, sentinel lymph node, intra-operative lymph nodes mapping, TNM staging, regional lymph nodes resection, number of lymph nodes examined, lymph node ratio, guiding adjuvant treatments, lymphatic targeted therapy.

Background and purpose:Ultrasound is a regular screening method of solid pseudopapillary tumor of the pancreas (SPTP). This study was to summarize the diagnostic value of ultrasound to SPTP.Methods:Clinical and ultrasound data of 62 SPTP cases in Fudan University Shanghai Cancer Center were retrospectively collected and analyzed.Results:Five cases of SPTP were undetected by ultrasound in the group. The features of ultrasound including: large mass located at the body and tail of the pancreas, clear boundary and regular shape, low ultrasound with uneven signal, or low signal mixed with no signal. A few cases have calciifcation and blood signal. Most of the cases presented no dilation of main pancreatic duct and bile duct and regional lymph nodes enlargement. Conclusion:Ultrasound can be used to detect SPTP which has special ultrasound signal features.

Pancreatic ductal adenocarcinoma (PDAC) is among the most devastating human malignancies. The poor clinical outcome in PDAC is partly attributed to a growth-permissive tumor microenvironment. In the PDAC microenvironment, the stroma is characterized by the development of extensive fibrosis, with stromal components outnumbering pancreatic cancer cells. Each of the components within the stroma has a distinct role in conferring chemoresistance to PDAC, and intrinsic chemoresistance has further worsened this pessimistic prognosis. The nucleoside analog gemcitabine (GEM) is usually the recommended first-line chemotherapeutic agent for PDAC patients and is given alone or in combination with other agents. The mechanisms of intrinsic resistance to GEM are an active area of ongoing research. This review highlights the important role the complex structure of stroma in PDAC plays in the intrinsic resistance to GEM and discusses whether antistroma therapy improves the efficacy of GEM. The addition of antistroma therapy combined with GEM is expected to be a novel therapeutic strategy with significant survival benefits for PDAC patients.
