Objective To study the effects of protein kinase C (PKC) inhibitor staurosporine (STS) on the proliferation and apoptosis of human cholangiocarcinoma QBC-939 cells and to explore its possible mechanism. Methods CCK-8 was used to detect the effects of PKC inhibitor STS on the proliferation of human cholangiocarcinoma QBC-939 cells. The effects of STS on the ultrastructural characteristics of QBC-939 cells were observed by routine transmission electron microscopy (TEM). The apoptosis rate and the cell cycle distribution of QBC-939 cells were detected by flow cytometry. The expression of cyclin B1,Cdk1 and p-Cdk1 in QBC-939 cells was detected by Western blotting. Results STS could significantly inhibit the proliferation of QBC-939 cells in a dose-dependent manner (P <0. 05) and the half inhibitory concentration ( IC50 ) of QBC-939 cells at 24th and 48th h was 334 nmol·L-1 and 118 nmol · L-1 , respectively. TEM observed that STS could induce typical apoptotic bodies and super-microstructural changes of QBC-939 cells. By Annexin V-FITC/ PI double labeling flow cytometry,we found that the apoptotic rate of QBC-939 cells after treatment with STS for 0,12,24 and 48 h was (10. 16±4. 52)% ,(22. 35±2. 19)% ,(34. 27±2. 30)% and (59. 70±5. 97)% ,respectively. By flow cytometry,compared with the control group,STS could significantly increase apoptosis rate of QBC-939 cells,decrease the percentage of cells in G0 / G1 phase and increase the percentage of cells in G2 / M phase (P<0. 05). Western blotting proved that the expression levels of cyclin B1 and Cdk1 proteins in the STS-treated QBC-939 cells were significantly decreased (P<0. 05),while the expression level of p-Cdk1 protein in the STS-treated QBC-939 cells was significantly increased ( P < 0. 05 ). Conclusion STS can significantly inhibit cell proliferation and induce apoptosis of human cholangiocarcinoma QBC-939 cells and the mechanism may be related to cell cycle arrest at G2 / M phase.

The integration of natural and human sciences has resulted in the evolution of the connotation and framework of medicine, thus enriching its scientific nature. The high degree of the integration of the scientific, technological, economic, and social factors in the field of the medical sciences with human sciences reveals the significance of the human spirit in medical care. Reliability, impartiality, effectiveness and satisfaction, which embody the human spirit in medical care, signify a hospital's character and core values and are the prerequisite and guarantee for satisfying medical care. The authors point out emphatically that the development of the codes of ethics and the human ideology in medical care constitutes both the core of the cultural construction of the modern hospital and an important foundation for its economic growth.

In view of the imbalance between basic research and clinical research in cancer,and the failure of timely and effective translation from basic achievement to clinical application,new insights to strengthen and accelerate the bidirectional translation between clinical issues and basic achievement have being widely accepted,with the definition of Translational Medicine as a link.With the rapid development of modern molecular biology and cell biology techniques,the strong power of high-throughput deep sequencing,epigenetics,and microenvironment research on exploring cancer biomarkers and interpreting the mechanisms of carcinogenesis and progression,has being taken seriously.Here,we will illuminate the role and further application of deep sequencing,epigenetics,and microenvironment based on analysis from clinical issues or samples in the current cancer research.

Computer science is not important enough in the medical university curriculum and students do not like this course. Therefore, game-teaching methods were employed to enrich teaching methods,to make medical teaching more vivid and to promote medical students' learning interests. In this paper,application of game-learning idea in the medical teaching process was discussed from multiple aspects including the story of the game,incentives of the game and the punitive measures of the game.

critical incidents are significant for the management of hospitals,and it may even be critical to the survival and development of the hospital.This article introduces a series of practices adopted by the First People's Hospital of Changzhou conducted in cases of crisis,and discusses the strategies and measures in hospital crisis management.

Objective To explore the effect of Danggui shaoyao powder combined with Sanhuang lotion fumigation on serum TGF-β1,IL-4 and IL-10 in the treatment of chronic pelvic inflammatory disease.Methods 38 cases with chronic pelvic inflammatory disease were selected and divided into the control group (19 cases) and the experiment group(19 cases) according to the random number table.The control group were treated with Sanhuang lotion fumigation bath, the experiment group were treated on the basis of the control group with Danggui shaoyao powder, 10 days for a course of treatment, a total of two courses of treatment.The serum IL-4, IL-10, TGF-β1 and clinical efficacy were compared before and after treatmentbetweentwo groups.Results The total effective rate of the experiment group was 94.74%, which was higher than 84.21% of the control group(P<0.05).After treatment, the clinical symptom score in experiment group was lower than that in control group, the serum levels of IL-4 and TGF-β1 were lower than those in control group, the serum level of IL-10 was higher than that in control group (P<0.05).Conclusion Danggui shaoyao powder combined with Sanhuang lotion fumigation could decreases IL-4 and TGF-β1 levels, increase IL-10 level and improve the inflammatory state in the treatment of chronic pelvic inflammatory disease.

OBJECTIVE:To discuss the effect of recombinant human growth hormone(HGH)on serum sndotoxin,inflamma-tory cytokines,wound healing time,hospitalization time and prognosis of elderly patients with severe burn. METHODS:96 elder-ly patients with severe burn in our hospital were randomly divided into treatment group (48 cases) and control group (48 cases). All patients received wound surface care,nutritional support,maintaining water and electrolyte and acid-base balance. Control group received 1 ml 0.9% Sodium chloride solution,sc,qd. Treatment group received 0.3 IU/kg. Recombinant HGH for injection, sc,qd. All patients were treated for 21 d. Serum endotoxin content in 2 groups before and 14,21 d after treatment was compared, inflammatory cytokines (TNF-α,IL-6, IL-8) before and after treatment,wound healing time,hospitalization time and the inci-dence of multiple organ disorder syndrome(MODS),death and systemic infection were observed. RESULTS:There was no signifi-cant difference in serum endotoxin content before and 14 d after treatment(P>0.05);after 21 d,serum endotoxin contents in 2 group obviously decreased,and treatment group was significantly lower than control group,with statistical significance(P<0.05). After treatment,IL-8 level in treatment group was significantly higher than control group,TNF-α and IL-6 were significantly lower than control group,with statistical significances (P<0.05). Wound healing time and hospitalization time in treatment group were significantly shorten than control group,with statistical significances(P<0.05). The incidence of MODS,death and systemic infec-tion in treatment group were significantly lower than control group,with statistical significances(P<0.05). CONCLUSIONS:The application of recombinant HGH in elderly patients with severe burn can reduce toxins absorption of patients and decrease inflamma-tory cytokines to promote wound healing and improve prognosis.

EBP50(ERM-binding phosphoprotein-50),a multifunctional adapter protein with 358 amino acids and two PDZ domains, regulates cell growth and migration. Lines of evidences indicate that it is a potential cancer suppressor protein. Loss of heterozygosity (LOH) and intragenic mutation of the ebp50 gene have been found in both primary breast tumors and breast cancer cell lines. EBP50 suppresses the breast cancer cell proliferation via its interaction with many tumor suppressor protein including PTEN, SYK, MERLIN, etc. Here the molecular structure of EBP50, signal pathway regulated by EBP50, and the relationship between breast cancer development and EBP50 are discussed.

From March 2004 to June 2007, the effect of the 32 Endopore implants which were placed in 25 patients with the inadequate alveolar jaw bone treated in the Implant Center of Department of Oral and Maxillofacial Surgery, the Affiliated Stomatological Hospital of Anhui Medical University were retrospectively analyzed. All patients were treated with Endopore implants of 5 mm ? 7 mm without any bone grafts simultaneously. Second-stage restoration was conducted 3-6 months later. Regular follow-up was between 1 and 4 years. All of the 32 implants gained osseointegration and were restored. During the follow-up, no implant loosed or lost. No inflammation was observed in the soft tissue around the implants. All the patients were satisfied with the final prostheses. With the unique root surface of porous microscopic titanium particle and the shorter design, Endopore implants can be used in the posterior area of inadequate alveolar jaw bone. They could improve the indication of the dental implant.
