Objective To investigate the expression of caspase-10 in differentiated thyroid carcinoma and association with its development and metastasis. Methods Thyroid samples from 37 patients in a period from January 2006 to December 2007, with differentiated thyroid carcinoma were retrospectively analyzed for caspase-10 by immunohistocbemistry(streptavidin-perosidase, S-P), compared to control group of 46 cases with nodtdar goiter. The relationship between the expression of caspase-10 and the clinical pathologic characteristics of thyroid carcinoma were also explored simultaneously. Results caspase-10 were observed as brown or yellow particles located in the cytoplasm or cell membrane of nodular goiter but there were no significant evidence for its positive expression in thyroid carcinoma, caspase-10 expression was markedly down-regulated in differentiated thyroid carcinoma(29.73%,11/37) compared with benign nodules(71.74%,33/46, χ2=14.528, P<0.01). The positive expression in 18 cases with lymph node metastasis(11.11%,2/18) was significantly lower than those in 19 patients without lymph node metastasis(47.37%,9/19; χ2=4.210, P<0.01). There was no significant correlation(P> 0.05) between the expression of caspase-10 and the clinical pathologic characteristics including male, age, TNM stage and pathologic type. Conclusion Down-regulation of caspase-10 may play a critical role in carcinogenesis and development of differentiated thyroid carcinoma.

Peptide drugs exhibit an irreplaceable role in clinics due to their high specificity, efficiency and low toxicity. At present, more than 80 peptide drugs have been approved for marketing with global sales exceeding $50 billion in 2019. However, with large molecular weights, high hydrophilicity and instability in digestive tract, oral peptide drugs encounter substantial physiological barriers leading to low oral bioavailability. Therefore, peptide drugs are mostly administered by parenteral routes. Although parenteral delivery of peptide drugs achieves high bioavailability, this is associated with inconvenience and discomfort, even causing severe side effects compared with the oral route possessing a high degree of patient compliance. Therefore, numerous studies concentrate on novel strategies to improve the oral bioavailability of peptide drugs. Some delivery technologies such as Eligen™ and Axcess™ have been successfully applied to the oral dosage form of therapeutic peptides and have accelerated relevant oral formulations for Food and Drug Administration (FDA) approval and clinical treatment. In this review, we focus on the oral peptide delivery, mainly summarizing the progress of recent strategies used to overcome oral barriers and the commercialization applications of related patents, which could facilitate the research and development (R&D) of clinical applications of oral delivery techniques for peptide drugs.

This study was designed to investigate the correlation between autophagy and polarization of macrophages in atherosclerosis (AS) plaque in arteriosclerosis obliterans amputees. Femoral artery specimens from arteriosclerosis obliterans amputees were performed hematoxylin and eosin (HE) staining, oil red O and immunofluorescence staining to observe the morphology of atherosclerotic plaque, phenotype of macrophages and autophagy in plaque; using real-time quantitative RT-PCR technology to detect the mRNA level of M1 and M2 type markers in arterial tissue; to analyze polarized signal pathway and autophagy protein levels in macrophages by Western blotting. Arterial specimens staining showed obvious lipid deposition and obvious infiltration of amount of foam cells and inflammatory cells. Macrophages were mainly expression M1 type in percentage in fibrous plaque. Although both M1 and M2 macrophages were upregulated in atheromatous plaque, the increase was dominant in M2 type in percentage. The level of autophagy was significantly higher in the atheromatous plaque than that of fibrous plaque. The expression of tumor necrosis factor- α (TNF-α), monocyte chemotactic protein-1 (MCP-1), inducible nitric oxide synthase (iNOS), interleukin-6 (IL-6) and interleukin-12 (IL-12) mRNA was significantly higher in fibrous plaque than that of atheromatous plaque (P < 0.01 or 0.05), and arginase-1 (Arg-1), transforming growth factor-β (TGF-β), CD163 and interleukin-10 (IL-10) mRNA was significantly lower than that in atheromatous plaque (P < 0.01). The levels of p-STAT1 and NF-κB were significantly increased in fibrous plaque (P < 0.01), while p-STAT6 expression was significantly increased in atheromatous plaque (P < 0.01). The level of LC3-II was significantly higher in atheromatous plaque than that in fibrous plaque (P < 0.01). Macrophages in early atherosclerotic plaque were induced to M1 type through p-STAT1/NF-κB pathway and expressed moderate levels of autophagy; while macrophages in advanced plaques were induced to polarization of M2 type through p-STAT6 pathway. M2 macrophages expressed a higher level of autophagy than M1 macrophages.

It's known to all that the refractory ascites treatment has so far been a very difficult clinical problem. We have extracted much experience from the practical techniques used in the refractory ascites treatments of more than 1,000 cases, and have developed the ascites ultrafiltration & concentration therapeutic instrument--FSCLZLY-A. The clinical applications show that it is very effective. Its effective rate is about 72.08%. Therefore, it is a very useful and important medical device for refractory ascites, for the improvement of renal function, and for the prevention of the infection of abdominal cavity.

Objective:To explore the function of Znf804a during brain development by using mouse model.Methods:The shRNA of Znf804a (shZnf804a) and control (pSUPER) plasmids were introduced into ventricular zone of ICR (Institute of Cancer Research) mice at E14.5 (three mice in each group) by using in utero electroporation.The speed of migration was evaluated by comparing the proportions of neuron in cortical plate (CP) zone.The proliferation speed was evaluated by comparing the diameters of neurospheres formed by neuron progenitor cells.The differentiation speed was evaluated by comparing the proportions of Nestin staining positive cells in neuron progenitor cells.Results:The proportion of neurons in CP zone was lower in shZnf804a group than in controls(11.8％ vs.75.4％,P ＜ 0.001).The diameter of neurospheres formed by neuron progenitor cells was bigger in shZnf804a group than in controls (295μm vs.172μm,P ＜0.01).The proportion of Nest in staining positive cells in neuron progenitor cells was larger in shZnf804a group than in controls (31.5％ vs.9.6％,P ＜0.01).Conclusion:It suggests that the migration speed of neurons in shZnf804a is lower than that in controls,the proliferation speed is higher than that in controls,and the differentiation speed is lower than that in controls.These results indicate that Znf804a may play an important role in the development of mouse brain.

Objective: To investigate the effects of preoperative sarcopenia on postoperative clinical outcome in patients with gastric cancer. Methods: A prospective study was performed in 93 patients with gastric cancer and the skeletal muscle mass was examined by bioelectrical impedance. The primary outcome was postoperative complications. The secondary outcomes were postoperative length of stay, overall hospital costs, 60 days re-admission and mortality rate. Results: A significant difference (sarcopenia group vs. non-sarcopenia group) was observed in the rates of overall postoperative complications, incidence of pleural effusion and intra-abdominal infection, overall hospital stay and postoperative hospital stay (P ＜ 0. 05). The rates of 60 days readmission, 60 days mortality and hospital costs in sarcopenia group were not different between the two groups (P ＞ 0. 05). By univariate and multivariate analysis, preoperative sarcopenia and preoperative nutritional risk are the risk factors of postoperative complications. Conclusion: Sarcopenia is an independent risk factor for postoperative complications in patients with gastric cancer; preoperative patients with sarcopenia have a worse prognosis and should be screened and optimized before surgery.

In the research and development of new drugs, it is very important to investigate the in vitro metabolism of candidate drugs. Traditional models such as liver microsomes have many limitations, while the in vitro model of recombinant human drug metabolizing enzymes is considered as an important and useful approach because of its convenient access, stable activity and low cost. In this study, six major human UDP-glucuronosyltransferases (UGTs) genes (UGT1A1, 1A3, 1A4, 1A6, 1A9 and 2B7) were cloned from human liver cDNA and heterologously expressed in Saccharomyces cerevisiae and baculovirus-infected insect cell. UGT1A1, 1A3, 1A6 and 1A9 were successfully expressed in yeast and showed glucuronidation activity against a variety of different structural types of substrates, but their activities were low. All six UGTs were successfully expressed and exhibited significantly improved glucuronidation activity when Trichopolusia ni cells BTI-TN5B1-4 (High Five) were used as the host. The recombinant human UGTs expressed in insect cells can catalyze the glucuronidation of their specific substrates, and the glucuronidation products were synthesized at milligram-scale with yields of 13%-66% for the first time, of which the structures were identified via MS, ¹H NMR, and ¹³C NMR spectroscopic analysis. Above all, the recombinant human UGTs yeast and insect cell expression systems constructed in this study can be used for in vitro metabolism evaluation in the early stage of new drugs research and development, and also provide a new tool for the synthesis of glucuronide metabolites.

OBJECTIVETo evaluate the exploratory development of bone graft by titanium mesh with bone allograft in treatment of cervical spinal tuberculosis.

METHODSThirty two cases of cervical spinal tuberculosis treated with anterior radical debridement, decompression and inter fixation from January 2002 to January 2007 were included (at least two years follow-up). 18 male and 14 female, age from 18 to 72, mean 41.3 years old. 0.5 - 15.0 months before visit, mean 6.9 months. There were 13 cases in initial treatment group and 19 cases in retreatment group. All cases were divided into two groups (group A and group B) by resource of bone graft. Group A, titanium mesh with bone allograft, 17 cases. Group B, autograft with ilium, 15 cases. Operation time, blood loss, curing conditions, cervical curvature (absolute rotation angle, ARA), function of spinal cord and the rate for bone graft fusions in two groups were compared. The mean follow-up was 3.5 years (range 2 - 5 years).

RESULTSThe primary healing rate of incisions was 93.8% (30/32), and total healing rate was 96.9% (31/32). There were no significant differences in operation time or in blood loss between two groups (P > 0.05). Operation time and blood loss, 72 min/121 ml in group A and 90 min/198 ml in group B, there were significant differences between two groups (P < 0.05). In each group, there were significant differences in the function of spinal cord between preoperative and immediately post operative, between preoperative and follow-up, and between immediately post operative and follow-up (P < 0.05), and there were significant differences in ARA between preoperative and immediately post operative, and between preoperative and follow-up (P < 0.05), and there were no significant differences between immediately post operative and follow-up (P > 0.05). On preoperative, immediately post operative and follow-up, there were no significant differences in the function of spinal cord or in ARA between two groups (P > 0.05).

CONCLUSIONFor cervical spinal tuberculosis followed by effective individual chemotherapy, a good effect can be obtained by treated with radical debridement and bone allograft with titanium mesh.
