A 28 days growth and development experiment and a 90 days intoxication experiment with —hydrochloro lysine at various dosage levels on young and adult rats were reported.The results were as follows. There were definitely an accelerating effect on growth and development in young rats when adding 0.5% L-lysine to a cereal diet, but no obviously similar effect in adult rats; moreover, a massive dose of L—lysine could induce hepatic and renal damage. The hepatic lesions were focal necrosis and increase of fat—storing cells with collagen fiber formation. In the kidney there were cloudy swelling, microvilli losing, intracellular edema, mitochondrial swelling, endopl asmic reticulum dilatation and residual body formation in the proximal convoluted tubule epithelium.

[Objective] The better optimization of traditional Chinese medicine for the treatment of respiratory syncytial virus, in the past five years is re-viewed in this paper, also the related domestic experimental research results, and according to the pathogenesis of RSV, it further summarizes the current domestic research for the main direction of the disease. [Methods] The article from the two aspects of compound Chinese medicine and traditional Chinese medicine monomer, according to the pathogenesis of respiratory syncytial virus section, discusses the experiment in vivo and in vitro related rich research results. [Results] It is found by inducing and summarizing, whether individual or compound traditional Chinese medicine, for respiratory syncytial virus re-search has made great achievement, but with experimental study limited to suppress the virus more value-added; replication and inhibiting inflammatory infiltrates the two big aspects, lacking of deeper side of molecular biology research, making the traditional Chinese medicine in the treatment of respiratory syncytial virus research appear too single, not a broader recognition by the industry. [Conclusion] We need to be sure the safety of traditional Chinese medicine for the treatment of respiratory syncytial virus and curative effect, but at the same time must recognize that because of the complexity of its com-position and design of experiment of traditional Chinese medicine, the irrationality of the existence of many factors, it makes progress with many problems, so we must be aware of their own insufficiency, more in-depth explore its mechanism of action, with al kinds of research direction in the future for us.

Much progress has been made in the diagnosis and treatment of Hodgkin's lymphoma, which has become a highly curable malignancy.However, prolonged survival makes clinicians pay more attention to long-term toxicities of treatment.Consequently, individualized treatment based on disease stage and risk factors is a research hotspot at present.This article reviews recent advances in the individualized treatment of early-stage classical Hodgkin's lymphoma.

Objective To investigate the effect of rosiglitazone on the expression of platelet CD40 ligand (CD40L) in insulin-resistant rats, and to further determine the relationship between CD40L and insulin resistance. Methods 60 healthy male SD rats [(200±20)g] were randomly divided into 4 groups: control group (C), high fat group (HF), low dose rosiglitazone group (LR) and high dose rosiglitazone group (HR). Rats in group C were fed normal chow diet, and the others were given high fat chow diet. After 12 weeks, high dose of rosiglitazone (10mg/kg) was given to rats in group HR and low dose of rosiglitazone (5 mg/kg) was given to rats in group LR for 4 weeks. Rats in group HF and group C were given 0.9% sodium chloride solution. The level of sCD40L was measured by ELISA and the expression of platelet membrane CD40L was detected by immunoprecipitation and Western blot. The insulin resistance (IR) index was calculated by homeostasis model assessment (HOMA). Results HOMA-IR, sCD40L level and platelet membrane CD40L expression were higer in group HF than in group C (9.8±3.2 vs. 5.9±1.7, 367.3 ±35.3 vs. 232.3±120.6, 2.1±0.4 vs. 1.4±0.2, respectively, all P<0.05). Compared with the group HF, HOMA-IR, sCD40L level and platelet membrane CD40L expression were obviously decreased in group HR(5.4±1.1, 276.9±54.0, 1.4±0.3, respectively, all P<0.05), and there were no significant differences in HOMA-IR, sCD40L level and platelet membrane CD40L expression between group HF and group LR (P>0.05). Conclusions In insulin-resistant rats, the level of sCD40L and the expression of platelet membrane CD40L were higher. After treatment with high dose of rosiglitazone, sCD40L level and platelet membrane CD40L expression were decreased with the improvement of insulin resistance.

Objective To evaluate the change situation of cognitive function in the patients with chronic renal failure (CRF) complicating obstructive sleep apnea syndrome(OSAS) .Methods Sixty‐two inpatients with non‐dialysis CRF in our hospital from September 2013 to January 2015 were selected and divided into the group O (complicating OSAS ,31 cases) and group N(without complicating OSAS ,31 cases) ,and contemporaneous 33 individuals undergoing the physical examination were taken as the control group(group C) .The cognitive function was evaluated by the Montreal cognitive assessment (MoCA) .The apnea hypopnea index (AHI) and lowest pulse oxygen saturation(LSpO2 ) at night were measured with a portable sleep monitor .The comparative analysis was performed .Results In the group O ,there was 14 cases of patients(45 .16% ) whose MoCA total score was less than 26 points , while there was only 3 cases(9 .68% ) in the group N ,the difference was statistically significant (P<0 .05) .The MoCA total score , scores of visuospatial and executive function ,attention ,delayed recall and orientation in the group O and N were lower than those in the group C ,while the MoCA total score ,attention and delayed recall in he group O were lower than those in the group N ,the score of language was lower than that in the group N and C ,the differences were statistically significant (P< 0 .05) .The MoCA total score was negatively correlated with serum creatinine and AHI (r= -0 .374 ,r= -0 .408 ,P<0 .05) ,and positively correlated with the GFR level and night LSpO2 (r=0 .382 ,r=0 .519 ,P<0 .05) .Conclusion The patients with CRF complicating OSAS increase the risk of cognitive impairment .
