This study aims to explore the temporal pattern of DNA breaks induced by nanosecond electric pulses (nsEP) in cisplatin-sensitive and cisplatin-resistant human ovarian cancer cells. Human ovarian cancer cells A2780 (cisplatin-sensitive subline) and C30 (cisplatin-resistant subline) were exposed to nsEP. Sham exposed groups were shame exposed to nsEP. Cell viability was determined using CCK-8 assay after 0 h, 4 h, 8 h, 12 h and 24 h, respectively, and the percentage of dead cells was calculated. The DNA break was detected with the alkaline single cell gel electrophoresis (comet assay), and the 75th percentiles of TL (tail length), TM (tail moment) and OTM (Olive tail moment) were measured. Cell viability displayed an early decrease and late increase, with the valley value seen at 8 h. Percentages of cell death and comet-formed in A2780 cells were higher than those in C30 cells (P < 0.05) at 8 h, respectively. TL, TM and OTM in C30 cells were less than those in A2780 cells (P < 0.05). The percentage of comet-formed correlated with that of cell death in either A2780 (r = 0.997, P < 0.05) or C30 (r = 0.998, P < 0.05) cells. DNA breaks induced by nsEP in cisplatin-sensitive cells differred from that in resistant cells, and DNA break resulted in fraction of cell death.

AIM: To explore the effect of lacrimal duct laser with lacrimal drainage tubes and stents implantation for complexity dacryagogatresia.
METHODS: There were 65 patients ( 82 eyes ) with compound tears nasolacrimal duct obstruction who received lacrimal drainage tubes and stents implantation after laser. The lacrimal duct stents were removed through nasal cavity after 1mo. Lacrimal drainage tubes were removed after 3-6mo. Follow-up periods were 6mo to 1a.
RESULTS: In the 65 patients (82 eyes), 71 eyes were cured, 5 eyes improved, the efficient rate was 93%; there were 6 eyes (7%) with epiphora.
CONCLUSION: Lacrimal duct laser with lacrimal drainage tubes and stents implantation was efficient for complexity dacryagogatresia.

To a certain extent, precision medicine based on individualized medical treatment process, like syndrome differentiation of traditional Chinese medicine. This paper mainly analyzed the similarities and differences of theory, practice and development between precision medicine and TCM syndrome differentiation. After the analysis, we found that these two medicine body could be integrated to improve the progress of medicine albeit some differences.

Evidence has indicated that low doses of anti-tumor regimens can induce cell apoptosis in vitro, although different regimens induce apoptosis by different mechanism and pathway. In recent years, new tumor treatment strategy has been mainly focused on inducing tumor cell apoptosis. The present review discusses the advantages and disadvantages of inducing tumor cell apoptosis. The benefit of inducing apoptosis is not to cause inflammatory reaction, but as its disadvantage, it inhibits immune responses, and the phagocytosis of apopotic bodies may result in horizontal transfer of genes (including oncogenes and other oncogenic materials), which can be one of the causes of tumor relapse. This paper proposes that the tumor treatment strategy should be turn into promoting tumor cell necrosis and inducing anti-tumor immune responses.

Objective To investigate the variation and correlation between tumor necrosis factor-?(TNF-?)and transforming growth factor-?1(TGF-?1)in children with Henoch-Schonlein purpura nephritis(HSPN)in plasma and explore their effects on kidney lesion in children with Henoch-Schonlein purpura(HSP).Methods Plasma TNF-? and TGF-?1 were determined with enzyme-linked immunosorbent assay(ELISA)in 30 cases with HSP,38 cases with HSPN and 30 normal controls,urinary protein excretion with urinary analyze method in these children.Renal biopsies were performed and renal biopsy specimens were observed by light,immunofluorescence and electron microscopy in 32 out of 38 cases with HSPN.The SPSS 11.0 software was used to analyze the data.Results 1.Comparing with normal controls,the plasma level of TNF-? and TGF-?1 in children with HSP increased with significant difference in statistics(Pa

OBJECTIVETo investigate the therapeutic effect of Yiqi Huaju Recipe (YHR) combined with routine therapy on the blood pressure, the blood pressure variability and other cardiovascular risk factors in hypertension patients complicated with metabolic syndrome (MetS).

METHODSTotally 43 hypertension patients complicated with MetS were recruited in this study and randomly assigned to the treatment group (22 cases, treated with basic routine treatment +YHR) and the control group (21 cases, treated with basic routine treatment + placebo). The treatment course was 12 weeks. Detected were parameters such as 24-h ambulatory blood pressure monitoring (ABPM), body mass index (BMI), waist circumference (WC), waist to hip ratio (WHR), homeostatic model assessment for insulin resistance (HOMA-IR), fasting glycosylated hemoglobin A1c (HbA1c), fasting plasma glucose (FPG), 2 h postprandial plasma glucose (2 h PPG), fasting plasma insulin (FPI), serum lipid, etc.

RESULTSThe anthropometric parameters and plasma glucose levels (except HbAlc) were obviously lowered after treatment than before treatment in the treatment group (P < 0.01, P < 0.05). Besides, better effects were obtained in the WC, WHR, 2 h PPG, FPI and HOMA-IR (P < 0.05). The average blood pressure amplitude, the blood pressure variability, and blood pressure load at any time point were more obviously improved in the two groups after treatment than before treatment (P < 0.01, P < 0.05). Besides, partial indices were better in the treatment group than in the control group (P < 0.01, P < 0.05).

CONCLUSIONSYHR combined with routine therapy exhibited better effect on reducing the blood pressure amplitude, the blood pressure variability, and the blood pressure load in hypertension patients complicated with MetS. It could also effectively decrease the risk of other vascular disease.

There has been thousands of years' history that traditional Chinese medicines were used in the prevention and treatment of infectious disease. In recent years, traditional Chinese medicine plays a unique role in the control of variety of new infectious diseases. This article provides a summary on our knowledge of the traditional Chinese medicine theory in the explanation of infectious disease, application of Chinese medicines and the pharmacological mechanism in the successful management on the Ebola virus disease.

Relapse, which puzzled several generations of hematologists, is the bottle-neck of radical treatment for leukemias. The progress of Human Microbiome Project at the beginning of 21st century suggested that human body was a super-organism constituted by the core of human cells and symbiotic microorganisms. The elucidation and characterization of endogenous retrovirus and prion protein suggested the possible effects of co-evolutional microorganisms on human health. Recently, the elucidation of the roles of tunneling nanotubes in intercellular communication and transportation suggested a novel way for cellular communication and transport of oncogenic materials. The role and significance of in vivo cell fusion have been studied in more detail. On the other hand, donor cell leukemia was reported. All of these approaches provide novel insights for studying the mechanism of leukemia relapse. Based on previous work, the authors suggest the hypothesis: there are two possible mechanisms for the relapse of leukemias: the minimal residual disease (MRD) and intercellular transportation of oncogenic materials.
