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.

Objective To analyze the evolution and genetic characterization of echovirus 11 (Echo11 ) from the acute flaccid paralysis (AFP) cases in Shandong province. Methods Isolation of Enterovirus was performed from stool samples of AFP cases from 1994 to 2009. All positive strains were sero-typed by neutralization test. Entire VP1 coding region from 27 strains typed as Echo 11 was amplified by reverse transcription-polymerase chain reaction(RT-PCR), and subsequently phylogenetic analyse on VP1 sequences from these strains and others published in GenBank were conducted. Results From 1994 to 2009, altogether 915 non-polio enterovirus (NPEV) strains were isolated with 79(8.6% ) isolates serotyped as Echo11. There were 876 nucleotides (nt) in the complete VP1 genes, encoding 292 amino acids (aa). The nt identities were 76.4%-100.0% among those Echo11 Shandong strains with the aa identities as 91.4% -100.0%. The nt and aa identities were 77.7%-80.7% and 90.7%-94.8% between Shandong strains and prototype strains, respectively.Conclusion All Echo11 strains could be divided into four genotypes. Shandong strains that forming three (A1, A2 and C1) new sub-genotypes, with every sub-genotype had several brands.Sub-genotype A1 appeared to be the lately circulating one.

OBJECTIVETo investigate the differentiation of human testicular spermatogenic cells during in vitro culture.
METHODSTesticular cells of obstructive azoospermic patients' testis biopsies were dispersed employing mechanic methods. Then, (1) mixed testicular cells were applied to in vitro culture, and changes of the ratio of elongating spermatids and all round cells were analyzed during mixed cell culture; (2) round spermatids were picked up from the mixed cells employing micromanipulator, followed by differentiation of the isolated round spermatids during microdrop culture.
RESULTSThe ratio of the elongating spermatids increased significantly (P < 0.05) after 24 hours of mixed cell culture in HTF medium supplemented with FSH and testosterone. During single round spermatid culture, transformation of the round spermatid to elongating spermatid with newly formed flagellum was observed, and the transformation ratio within 48 hours of microdrop culture was 3.54%. The differentiation of human testicular spermatogenic cells cultured in Vero cell conditioned medium was similar to that cultured in HTF medium.
CONCLUSIONHuman testicular round spermatids can differentiate to elongating spermatids during in vitro culture. Vero cell conditioned medium does not promote the differentiation of human testicular round spermatids to elongating spermatids.

In previous study, molecular typing method was performed to identify human enteroviruses (HEVs) isolates collected from acute flaccid paralysis (AFP) cases from 1989 to 2011 and hand, foot and mouth disease (HFMD) patients, and 8 HEV-A serotypes were identified. In order to explore the genotypes and molecular evolution characteristics of HEV-A in Shandong province, viral RNA of the remaining isolates was extracted and entire VP1 coding region was amplified, sequenced and identified with HEV-A primers. Another 7 HEV-A Shandong isolates were obtained, and identified as Coxsackievirus A (CVA) 2, 6, 8 and 12 by molecular typing method. Homologous comparison showed that the nucleotide acid identities of Shandong strains ranged from 80.8% to 85.0% with prototype strains. Phylogenetic analysis based on VP1 sequences indicated that CVA8 and CVA12 strains were genetically related with domestic strains. However, CVA2 and CVA6 strains were distinct from both domestic and foreign strains. In addition, multiple transmission chains of CVA2 and CVA6 existed within Shandong province. So far, a total of 12 HEV-A serotypes were identified in Shandong province. This study enriched the distribution of serotypes and genetic evolution characteristics of HEV-A isolates in Shandong, and revealed different transmission chains of CVA2, 6, 8, 12 serotypes co-circulated in Shandong province or in China.

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.

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.

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.
