OBJECTIVE: To observe the effects of Xuanyinning Recipe (XYNR) in inhibiting SPC-A-1 cellular infiltration and on the pathomorphological changes of peritoneum in mice inoculated with sarcoma 180 (S(180)). METHODS: On the bases of isolated culture of mouse peritoneal mesothelial cells, we adjusted and added the human lung adenocarcinoma cell line SPC-A-1 into the double-layer culture medium to observe the number of clones formed. We also took out the peritoneum from the mice administered with three different dosages of XYNR and observed its pathomorphological changes with transmission electron microscope. RESULTS: In the in vitro experiment, the number of clones of SPC-A-1 in culture medium with XYNR (50 microg/ml) decreased distinctly. In the in vivo experiment, it was observed that, in the peritoneum from the XYNR-treated mice inoculated with S(180), the mesothelial cells arranged more and more regularly with the increasing of the dosage of XYNR, while the mesothelial cells in the peritoneum of the mice in the control group necrosed and arranged loosely. CONCLUSION: XYNR can inhibit the invasion of SPC-A-1 cells. It also can improve the loose arrangement of the peritoneal mesothelial cells in mice inoculated with S(180), so as to inhibit the malignant effusion.

Objective:To observe the influence of Xinfeng capsule(XFC) on pulmonary HRCT images and cytokines(TNF-?,IL-10) in blood serum adjuvant arthritis rats.Methods:60 rats were averagely divided into normal control group,model control group,methotrexate(MTX) treated group,tripterygium wilfordii polycoride tablet(TPT) treated group, XFC treated group,12 in each.Except for the rats of normal group,the others were intracutaneously injected with 0.1 ml of Freund’s complete adjuvant in the right hindlimb.After 19 days,different drugs were given to all rats. Pulmonary HRCT images were obtained and the blood samples were reserved for assaying cytokines.Results:In model control group ,the lungs’ outlines weren’t clear and the blood vessels expanded with the edges of them being obscure and unregular. There were high density images shaped as rope and slip in lungs of model control group rats and the pleura near the images were a little thickening. In MTX treated group, there were high density images shaped as slice along pulmonary veins. The veins of the blood vessels were obscure and the edges were unclear. In TPT treated group,there were multiple high density images shaped as tubercle and slice and the boundary were not clear. In XFC treated group, the lungs’ outlines were clear and the veins were well-distributed. High density images shaped as spot were found in part lungs. Compared with normal control group,tumor necrosis factor-?(TNF-?) in blood serum ascended obviously in model control group(P0.05).Conclusion:XFC eliminates swelling by down-regulating the levels of TNF-?, up-regulating the levels of IL-10, restraining the inflammatory reaction.In adittion,cytokines participated in forming pulmanory fibrofication.So the changes of pulmanory HRCT images were also improved at the same time.

Sepsis is a high-risk factor for the death of critical patients. High density lipoprotein (HDL) are the major protective serum proteins, and the serum levels of HDL are closely related to the severity of sepsis. The anti-inflammatory and anti-oxidation properties of HDL, may be able to play an important role in the innate immune response. Thereby it may reduce the damage of septic shock and multiple organ dysfunction syndrome (MODS) in animals or human beings, and improve the prognosis. In order to unveil the metabolism of HDL in septic patients and its effects on both progression and prognosis of sepsis, this review not only focuses on the composition and structure of HDL, but also analyzes its pivotal role in inflammatory immune response and anti-oxidation.

Objective To study the relationship between overlapping symptoms (OS) and psycho- mental factors in patients with functional dyspepsia (FD) in order to understand the possible mechanisms of OS.Methods One hundred and three FD patients diagnosed by Rome Ⅲ criteria were divided into with or without OS groups by Rome Modular Questionnaire.The emotional status,sleep status,anxiety and depression status were evaluated by Zung Anxiety and Depression Scale and quality of life was eveluated by SF-36 questionnaire.The results were compared between the two groups.Results The proportion of the patients with and without OS accounted for 62.5% and 37.5%,respectively.The patients with OS had a worse emotional status ("bad%" and "very bad%" being 39.1% and 20.2% vs.15.4% and 12.8%,P=0.018) and a worse sleep status (45.3% and 11.0% vs.19.1% and 7.7%,p=0.018)than those without OS.The proportion of the patients with anxiety (49 % ) and depression (68 % ) status in OS group was significantly higher than that in without OS group (19% and 44%,respectively,P<0.05). The quality of life of the patients with OS was worse in the dimensions of psychological health (47.9), vitality (47.1) and mental component score (32.8)than those in without OS group (57.8,57.0,37.0, respectively,P<0.05).Conclusions The psycho-mental factors are associated with overlapping symptoms in patients with FD,which suggests that abnormal psycho-mental factors may be involved in the mechanisms underlying overlapping gastrointestinal symptoms in FD.

Objective To explore whether the pathophysiological mechanisms are same or not in different subtypes of functional dyspepsia (FD) patients. Methods Severity of symptoms and (44.2± 14. 6) years. Multi-gastrointestinal functions were also tested. Results No statistical difference was found among epigastric pain syndrome (EPS), postprandial distress syndrome (PDS) and mixed type in the data of gastric emptying function, gastric myoelectrical activity, autonomic nerve function,simultaneous introgastric pressure and water loading test, and psychological status assessment as well (P>0.05). There was a positive linear correlation between postprandial fullness and half gastric emptying time (correlation coefficient=11.5, P= 0. 043). Early satiation was negatively related to maximal water intaking volume (correlation coefficient=-6. 8, P=0. 033). Conclusions In this study, it suggested that the FD patients with different pathophysiologic mechanisms cannot be distinguished efficiently according to Rome Ⅲ criteria, and then be treated in a well-targeted manner.
