ABSTRACT
ObjectiveTo explore effect of Huanglian Jiedutang （HLJDT） on autophagy-related protein expression in septic mice with liver injury induced by cecal ligation and puncture （CLP）. MethodSixty eight-week-old C57BL/6 mice were randomly divided into four groups， namely， the sham operation group， model group， and low- （1.44 g∙kg-1） and high-dose （2.88 g∙kg-1） HLJDT groups， with 15 in each group. The septic model was established by CLP after the last administration of HLJDT for three successive days. The survival rate of mice with 24 h was observed. The mice were sacrificed 12 h after operation for collecting the serum and liver tissue. The levels of serum interleukin-6 （IL-6）， tumor necrosis factor-α （TNF-α）， and interleukin-1β （IL-1β） were detected by enzyme-linked immunosorbent assay （ELISA）， and the levels of alanine aminotransferase （ALT） and aspartate aminotransferase （AST） in serum by biochemical method. The pathological changes in liver tissue were observed by hematoxylin-eosin （HE） staining， and the apoptosis index （AI） of hepatocytes by TdT-mediated dUTP-biotin nick end-labeling （TUNEL）. The expression levels of protein high-mobility group box 1 protein （HMGB1）， Beclin1， and microtubule-associated protein 1 light chain 3 （LC3）-Ⅱ/Ⅰ in the liver tissue were assayed by Western blot. ResultCompared with the sham operation group， the model group showed reduced survival rate at 12 and 24 h， elevated IL-6， TNF-α， and IL-1β levels， enhanced AST and ALT activities （P<0.05）， hepatocyte swelling， inflammatory cell infiltration， and apoptosis， and up-regulated HMGB1 （P<0.05）， Beclin1， and LC3-Ⅱ/Ⅰ （P<0.05）. Compared with the model group， each medication group exhibited increased survival rate at 12 and 24 h， lowered IL-6 and TNF-α levels， weakened AST and ALT activities （P<0.05）， alleviated liver injury and apoptosis （P<0.05）， down-regulated HMGB1 expression （ P<0.05）， and up-regulated Beclin1 and LC3-Ⅱ/Ⅰ （P<0.05）. ConclusionHLJDT alleviates the liver injury of septic mice possibly by inducing autophagy and inhibiting apoptosis.
ABSTRACT
HSP90 is widely expressed in cells with the main function in assisting the maturation of other proteins that are called clients. Many clients play critical roles in the occurrence and development of cancer. Inhibition of HSP90 can lead to degradation of the oncogenic proteins, and result in potent anti-cancer effects. HSP90-HOP interaction is critical for the chaperone function of HSP90, thereby disruption of the HSP90-HOP interaction is a novel strategy in the inhibition of HSP90. Based on the technology of homogeneous time-resolved fluorescence (HTRF), we developed a new assay for the identification of new inhibitors of HSP90-HOP interaction. This method was evaluated in the study of the HSP90-HOP inhibition activity of the pentapeptide MEEVD from HSP90 C-terminal and its derivatives. This study can provide a basis for the screening and discovery of novel HSP90-HOP disruptors.
ABSTRACT
@#AIM:To investigate the effect and local influence of atropine and anisodamine eye drops on adolescent pseudomyopia. <p>METHODS:Totally 110 cases of juvenile pseudomyopia were randomly divided into two groups, the control group was given 10g/L atropine sulfate eye gel, and the observation group was treated with 5g/L raceanisodamine eye drops. The efficacy of two methods, the changes of axial length and intraocular pressure before and after treatment, and the incidence of adverse reactions were compared. <p>RESULTS: There was no significant difference in cure rate between the two groups(<i>χ</i><sup>2</sup>=0.533, <i>P</i>=0.465), but the effective rate of observation group was significantly better than the control group(<i>χ</i><sup>2</sup>=3.907, <i>P</i>=0.048). Compared with the same group before treatment, the length of the axial length of the two groups increased in different degrees,and the increase value of the observation group was significantly higher than that of the control group, the difference was statistically significant(<i>P</i><0.05), however, there was no significant difference between the two groups after treatment(<i>P</i>>0.05). The intraocular pressure of the two groups was significantly lower than that of the same group before treatment, and the difference between the two groups after treatments was not statistically significant(<i>P</i> >0.05). The incidence of adverse reactions in the observation group was significantly lower than that in the control group(<i>χ</i><sup>2</sup>=18.939, <i>P</i><0.05). <p>CONCLUSION: Anisodamine eye drops in the treatment of juvenile pseudomyopia has obvious curative effect, its efficacy and safety are better than atropine eye gel.
ABSTRACT
In this study, the tanshinone ⅡA loaded albumin nanoparticles were prepared by high pressure homogenization method. The formulation was optimized by central composite design-response surface method (CCD-RSM), with the particle size, encapsulation efficiency, and drug loading as indexes to investigate their in vitro anti-tumor effect. The results showed that the prepared nanoparticles had uniformly spherical morphology and uniform particle size distribution. The average particle size, encapsulation efficiency and drug loading of nanoparticles were about (175.7± 3.07) nm, 90.8%±1.47% and 5.52%±0.09%, respectively. Tanshinone ⅡA loaded albumin nanoparticles showed a more powerful antitumor effect than free tanshinone ⅡA for human promyelocytic leukemia NB4 cells. The preparation method of the drug-loaded albumin nanoparticles was simple and easy, and can significantly improve the solubility of tanshinone ⅡA, so it was helpful to extend its application in therapies against hematological malignancies.
ABSTRACT
The gene types of breast cancer can be classified into three types according to its molecules: Luminal type A, Luminal type B, HER-2-positive type, triple negative type. Authors combined pathological characteristics of breast cancer, biological characteristics, and comprehensive treatment, used syndrome typing based medication, and explored treatment meticulous ideas and methods of "treating the same disease with different methods" as well as "different treatment methods in accordance with patients individually".

<p><b>OBJECTIVE</b>To investigate the efficacy of combined modality therapy for small cell lung cancer (SCLC) patient with limited stage disease (LD).</p><p><b>METHODS</b>The data of 122 SCLC patients with limited stage disease treated by surgery combined with chemotherapy and radiotherapy were analysed retrospectively.</p><p><b>RESULTS</b>The median survival time (MST) of the 122 patients was 38 months, the 1-, 3-, 5-year survival rate was 83.6%, 50.0% and 38.0%, respectively. If stratified the patients by TNM stage, the MST of stage I was not reached yet, it was 52 months for stage II and 22 months for stage III (P = 0.001); the 5-year survival rate was 57.1%, 43.1% and 28.3%, respectively. For stage III, the MST and 5-year survival rate was 40 months and 45.3% for the patients who received postoperative chemoradiotherapy, and only 20 months and 26.1% for those who were treated with postoperative chemotherapy alone (P = 0.071).</p><p><b>CONCLUSION</b>Combined modality therapy can improve the survival of small cell lung cancer patient with limited stage disease, and TNM stage is still a significant prognostic factor.</p>
