The essence of endogenous turbidity in Chinese medicine (CM) is different from cream, fat, phlegm, retention, damp, toxicity, and stasis. Along with the development of modern scientific technologies and biology, researches on the essence of endogenous turbidity should keep pace with the time. Its material bases should be defined and new connotation endowed at the microscopic level. The essence of turbidity lies in abnormal functions of zang-fu organs. Sugar, fat, protein, and other nutrient substances cannot be properly decomposed, but into semi-finished products or intermediate metabolites. They are inactive and cannot participate in normal material syntheses and decomposition. They cannot be transformed to energy metabolism, but also cannot be synthesized as executive functioning of active proteins. If they cannot be degraded by autophagy-lysosome or ubiquitin-prosome into glucose, fatty acids, amino acids, and other basic nutrients to be used again, they will accumulate inside the human body and become endogenous turbidity. Therefore, endogenous turbidity is different from final metabolites such as urea, carbon dioxide, etc., which can transform vital qi. How to improve the function of zang-fu organs, enhance its degradation by autophagy-lysosome or ubiquitin-prosome is of great significance in normal operating of zang-fu organs and preventing the emergence and progress of related diseases.

Objective　To study the expressions of some apoptosis related to genes in lung tissues and their relationship to the pathogenesis in rats to hypoxic pulmonary hypertension (HPH). Methods　A total of 60 rats were employed and equally divided into 5 groups, i.e. control, HPH, hemin, Tin Protoporphyrin (Snpp) and low concentration CO groups. Of them, the rats from middle 3 groups were treated with hypoxia under normal pressure for 7 h in every day, 3 weeks except Sunday. Hemin and Tin Protoporphyrin (Snpp) were given half an hour before hypoxia while low concentration CO after 2 h of hypoxia. The expression of bcl-2, bax, Fas and Fas ligand (FasL) were detected with immunohistochemical staining, in situ cell death detection, DNA fragment detection, and in situ hybridization. Results　In low concentration CO and hemin group, typical DNA ladder bands and apoptotic cells were found in lung tissues, and the expressions of Fas, FasL, bax, and bcl-2 mRNA were increased in the epithelial cells of alveoli, vascular and bronchial walls. And the expression of bcl-2 mRNA was decreased than in hypoxic group. Conclusion　CO can regulate the expression of bcl-2, bax, Fas and FasL, these apoptotic genes may involve in the regulation of cell apoptosis of lung tissues under HPH and play important roles in the genesis and development of chronic obstructive lung disorders.

BACKGROUNDTanis was reported as a putative receptor for serum amyloid A (SAA) involving glucose regulated protein in insulin regulated resistance. It was found to be dysregulated in diabetic rats (Psammomys obesus, Israeli sand rat) and its homologue for humans is SelS/AD-015. The present study analyzed mRNA expression of SelS in omental adipose tissue biopsies from patients with type 2 diabetes mellitus (T2DM), and age- and weight-matched nondiabetic patients, the relationship of SelS mRNA with Homa-IR and serum SAA level.

METHODSHuman omental adipose tissues from ten cases of type 2 diabetic patients and twelve cases of nondiabetic individuals were analyzed for the expression level of SelS mRNA by semiquantitative polymerase chain reaction (PCR), Homa-IR estimated by standard formula and SAA level by enzyme-linked immunosorbent assay (ELISA).

RESULTSSelS mRNA expression, Homa-IR and serum SAA were higher in T2DM sufferers than in nondiabetic control group. SelS mRNA level was positively correlated with Homa-IR and SAA level in each group.

CONCLUSIONSSelS protein may be involved in insulin resistance in Chinese with T2DM by acting as the SAA receptor, thus playing an important role in the development of T2DM and atherosclerosis.

OBJECTIVETo investigate the effects and the related mechanisms of the components of Dang-Gui-Bu-Xue decoction (DGBXD) on improving blood deficiency.

METHODThe effects of promoting hematopoietic function were observed with the blood difficient model mice, by giving components of DGBXD. RBC, WBC, reticulocytes and bone marrow nucleated cells (BMNC) were determined. The components of DGBXD on proliferation of BMNC and on clony forming unit (CFU) were also determined.

RESULTThe components of DGBXD remarkably increased the quantity of RBC, WBC, and BMNC. Some of the components promoted the proliferation of BMNC and increased the quantity of CFU-Mix. Among them, polysaccharide of angelica was most potent.

CONCLUSIONThe studies show that the extracts and some components of DGBXD can promote the hemopoietic function system of the model mice, and they exert the effects in a comprehensive way.

OBJECTIVETo examine the correlation between the health-related quality of life measured by the St. George's Respiratory Questionnaire (SGRQ) and the commonly used physiological measures in lymphangioleiomyomatosis (LAM).

METHODSThis study retrospectively analyzed the SGRQ scores and other measures (the Borg scale of breathlessness at rest, 6-minute walking distance, blood oxygen levels, and pulmonary function) of patients diagnosed and confirmed with LAM. Altogether 38 patients between June 2007 and November 2009 were included.

RESULTSThe mean values of the SGRQ three components (symptoms, activity, and impacts) and total scores in the LAM patients were 46.95 +/- 28.90, 58.47 +/- 25.41, 47.89 +/- 29.66, and 51.11 +/- 26.35, respectively. The SGRQ total or component scores were correlated well with the Borg scale of breathlessness, 6-minute walking distance, partial pressure of oxygen in arterial blood, spirometry and diffusion capacity of lung. There were poor correlations between SGRQ score and residual volume or total lung capacity. In our preliminary observation, sirolimus improved the SGRQ total and three component scores and the Borg scale of breathlessness significantly after 101-200 days of treatment (n = 6).

CONCLUSIONSThe SGRQ score in LAM is correlated well with physiological measures (Borg scale of breathlessness, 6-minute walking distance, blood oxygen levels, and pulmonary function tests). The SGRQ could therefore be recommended in baseline and follow-up evaluation of patients with LAM. Treatment with sirolimus, an inhibitor of mammalian target of rapamycin, may improve the quality of life and patient's perception of breathlessness in LAM.

BACKGROUNDThe mammalian target of rapamycin (mTOR) pathway, a key cellular signaling pathway associated with various cellular functions, has distinct roles in the inflammatory process. In this study, the mTOR inhibitor rapamycin (Rapa) was used to test whether inhibition of mTOR activation attenuates lipopolysaccharide (LPS)-induced acute lung injury (ALI) in a murine model.

METHODSMice pretreated with Rapa or vehicle were given LPS intratracheally. Local cell numbers and inflammatory cytokines present in the bronchoalveolar lavage fluid (BAL), wet-to-dry weight ratio, histopathology of the lungs, and survival were evaluated.

RESULTSThe phosphorylation of S6, a major downstream target of mTOR, had a 3-fold increase in lung tissue after LPS stimulation, but the increase was blocked by Rapa. Rapa reduced the levels of TNF-α (LPS vs. LPS + Rapa, (1672.74 ± 193.73) vs. (539.17 ± 140.48) pg/ml, respectively; P < 0.01) and IL-6 (LPS vs. LPS + Rapa: (7790.88 ± 1170.54) vs. (1968.57 ± 474.62) pg/ml, respectively; P < 0.01) in the BAL fluid. However, Rapa had limited effects on the overall severity of ALI, as determined by the wet-to-dry weight ratio of the lungs, number of neutrophils in the BAL fluid, and changes in histopathology. In addition, Rapa failed to reduce mortality in the LPS-induced ALI model.

CONCLUSIONSWe confirmed that mTOR was activated during LPS-induced ALI and strongly inhibited by Rapa. Although Rapa reduced the levels of the mediators of inflammation, the overall severity and survival of the ALI murine model were unchanged.
