Human papillomavirus type 16(HPV 16)is associated with many tumor carcinogenesis particularly cervical cancer.HPV 16 variants has been found to show different geographic and ethic distributions according to epidemiologicat research.meanwhile,they also play an important role in virus persistent infections and disease progressions.Variants study has been a promising field in the research of HPV and its association with tumor research.

Objective To explore the experience of surgical treatment for appendiceal carcinoid.MethodsThe clinical data of 12 appendiceal carcinoid cases received surgery were retrospectively studied.ResultsPreoperatively,all the 12 cases were considered as appendicitis.The definite diagnosis was verified by pathologic study postoperatively.Among the 12 cases, tumors less than 1 cm 9 cases, between 1 cm to 2cm 2cases, but without serosal involvment or lymph node metastasis(2 cases) recieved simple appendectomy.One case with a tumor larger than 2cm and serosal involvment underwent fight hemicolectomy.ConclusionOwing to its lack of specific symptoms,the diagnosis of appendiceal carcinoid was usually reached after operation.The choice of surgical procedures should based on the size and depth of invasion of the tumor and lymph node metastasis status.

OBJECTIVE: To summarize the advances in the genetic susceptibility to coronary artery disease (CAD) and explore the heritable basis of the disease.DATA SOURCES:Related articles in English from January 1990 to June 2006 were searched in Pubmed and EMCC databases with the terms "gene, coronary artery disease and myocardial infarction". Meanwhile, the CMCC database was searched for the relevant articles published between January 2000 and June 2006 in Chinese.STUDY SELECTrON: After the preliminary selection,relevant literatures on genetics of CAD and myocardial infarction(MI)were selected, and those with obvious indifferent contents or with less correlation were excluded.DATA EXTRACTION: Data of 49 articles were mainly extracted from the selected literatures providing solid evidence to elucidate the genetic susceptibility to CAD or MI.DATA SYNTHESIS: The involved 49 articles showed that CAD is a complex multifactorial disorder which is believed to result from the interplay between a person's genetic makeup and various environmental factors. The heritable basis is increasingly recognized as a crucial component in the development of CAD. Recent work in the field of genetics has lead to determining key genes associated with the susceptibility for CAD and MI through genome-wide linkage scans and large-scale gene-association studies as core human genetics approaches These susceptibility genes involve diverse functions, including dyslipidemia, vascular homeostasis, endothelial dysfunction, inflammation and immunity.CONCLUSION: The identification of genes that predispose to or directly cause CAD provides new insights into the pathogenesis of this disorder. However, the precise role of genetic factor in the CAD or MI events and the personalized gene-specific therapy await further investigation.

After the basic properties of literature-related citation network, co-authorship network and co-words network were analyzed and the advances in their application research were summarized in aspects of their construc-tion methods, size and research depth, it was pointed out that article similarity networks could be constructed using the article similarity algorithm, and their basic properties and features were analyzed.

Objective To investigate the injury effects and mechanisms of circulating histones on the hepatocytes in patients with hepatitis B virus (HBV )-related liver failure (HBV-LF) .Methods Serum samples from patients with HBV-LF were collected . The levels of serum histone H3 , histone H4 , prothrombin activity (PTA ) ,total bilirubin (TBil) ,creatinine (Cr) and international normalized ratio (INR) of the patients were measured .Model for end-stage liver disease (MELD) score was calculated in the patients .The serum levels of histones were compared between patients and the healthy volunteers . The correlation of histones with the MELD score and PTA was analyzed .The human liver cell line L-02 cells were cultured and treated with the serum of patients or L-02 cellular lysate supernatant preincubated with or without anti-histone H3 and H4 antibodies .The cellular morphology and rate of apoptosis were observed .Intracellular calcium ion concentration and Caspase-3 activity were detected in the cultured L-02 cells treated with histones .Mean of two independent samples was compared using t tests .Relationship between histones and the MELD score or PTA was conducted using Spearman correlation analysis .Results The levels of serum histones in the patients with HBV-LF were much higher than those in the healthy volunteers (H3 :[5 390 .3 ± 1 032 .0] μg/mL vs [42 .7 ± 12 .8] μg/mL , t = 32 .76 , P < 0 .01 ; H4 :[4 205 .1 ± 662 .3] μg/mL vs [40 .3 ± 14 .6] μg/mL ,t = 39 .74 , P< 0 .01) .In addition ,serum histones (H3/H4) levels in patients were negatively correlated with serum PTA (r= - 0 .325 ,P= 0 .038 and r =- 0 .572 ,P= 0 .028 ,respectively) ,but positively correlated with the MELD score (r= 0 .359 ,P= 0 .021 and r = 0 .568 , P = 0 .007 , respectively ) . Both serum of patients with HBV-LF and L-02 lysate supernatant were toxic to cultured L-02 cells .The injury effect was inhibited by anti-histone antibodies ([9 .3 ± 1 .5]% vs [14 .3 ± 0 .6]% , t = 4 .259 , P= 0 .02) .L-02 cells treated with calf thymus histone were cultured for 4 h . Cellular toxicity of histones resulted in Caspase-3 activation . The effect was inhibited by anti-histone antibodies ([3 .5 ± 0 .5]% vs [5 .2 ± 0 .6]% ,t= 4 .243 ,P= 0 .02) .Conclusion The elevated circulating histones in the patients with HBV-LF may aggravate the liver damage .

This article consults the literature on acupuncture-moxibustion treatment for the non-spastic stage of cerebral stroke published from 2001 to 2014, makes a summary and analysis from meridians, point selection, acupuncture reinforcing-reducing techniques and electoacupuncture application and points out some problems such as valuing acupuncture and neglecting moxibustion, valuing acupuncture and neglecting medicine, and neglecting point selection based on syndrome differentiation in acupuncture-moxibustion treatment for the non-spastic stage of cerebral stroke. The article also objectively assesses the position of acupuncture-moxibustion treatment, puts forward relevant solving ideas and emphasizes the importance of acupuncture manipulation and the necessity for combining Chinese herbal medicine to treat the non-spastic stage of cerebral stroke.

Objective To study the influences of risk factors on the 2-week mortality in patients with acute cerebral hemorrhage.Methods From January 2004 to June 2007,a total of 65 patients with intracerebral hemorrhage in Beijing Red Cross Hospital were studied.Logistic regression was performed to analyze the relationship between prognostic factors and 2-week mortality.These factors included sex,age,volume of hemorrhage,location of hematoma,the highest body temperature in the first 24 h,and consciousness state on admission etc.Results The in-hospital mortality in 2 weeks was 18.5%(12/65).The volume of hemarrhage,body temperature and consciousness state were probably significant factors.Conclusion The increasing body temperature in the first 24 h and the unconsciousness may be the main risk factors which are associated with high 2-week hospital mortality in patience with intracerebral hemorrhage.

Text mining provides a new approach for drug repositioning, and the emerging databases and their corresponding tools provide more and more convenience for drug repositioning by text mining.The methods and tools for studying drug repositioning by text mining and their successful application examples were thus described in this paper in order to provide reference for the researchers interested in this field.

In this study, we selected 24 crewmen who worked in the high temperature circumstances in the engine cabin, resulting in a great loss of body water, together with a large amount of inorganic salts and nitrogen. We Proved that the loss of sodium, potassium, and calcium in sweat is greater than that in urine. The excretion of sodium is the highest, then potassium, the lowest is calcium. The body weight of the engine member has a prominent decrease after summer. It seems that the regaining of body weight can be promoted by great supply of vitamins. So, we should give a large amount of proteins, vitamins and calcium to the members who worked in the circumstance of such a high temperature. The amount of salt is already quite enough in an ordinary meal.
