Cone-beam computed tomography (CBCT) has an important function in understanding implant operations. CBCT can be used to evaluate the basic condition of implant site before implant operation and decide whether it is suitable for implanting. CBCT also ensures whether the direction of implant and the operation method are satisfactory. CBCT can be used pre- or post-operation as long as the case involves the maxillary sinus. Clinical implant cases using CBCT were introduced to evaluate the maxillary sinus pre- or post-operation.

Spontaneous internal carotid artery dissection is a group of (c)linical uncommondiseases,but it is a potentially catastrophic non-traumatic acute critical illness.The improvement of knowledge and understanding of the disease by clinicians will help to take preventive measures and improve the levels of diagnosis and treatment.This article reviews the advances in clinical features,diagnosis and treatment of spontaneous internal carotid artery dissection.

Objective To investigate the efficacy and toxicity of thalidomide plus irinotecan and cisplatin treatment for recurrent small cell lung cancer.Methods 62 Patients with recurrent small cell lung cancer in the same period were randomly divided into observation group and control group according to the principle of minimum distribution imbalance index.The observation group patients were treated with thalidomide plus irinotecan and cisplatin chemotherapy,and the control group patients were treated with irinotecan and cisplatin chemotherapy.The efficacy and toxicity of the two groups were compared.Results The overall response rate in the group observation was 86.7％ compared with 63.3％ in the control group,and the difference had statistical significance (x2 =8.52,P ＜ 0.05).The major toxicities were hematologic toxicity and gastrointestinal symptoms,and the side effects differences were not statistically significant (x2 =0.18,P ＞ 0.05).Conclusion The treatment of recurrent small cell lung cancer with irinotecan and cisplatin in combination with thalidomide has high efficiency,and the toxicity can be tolerated.

Apolipoprotein M (apoM) is a novel apolipoprotein discovered in 1999 and belongs tothe lipocalin protein superfamily.The APOM gene is mainly expressed in the liver and kidney,Where it is highly regulated by transcription factors,cytokines,hormones etc.Series of studies have shown that apoM plays an important role in lipoprotein metabolism especially in high-density lipoprotein (HDL).Since the relationship between HDL and atherosclerosis (AS) has been well known,apoM is supposed to be of potential fuctional importance in AS.Here we review the progress made in understanding the characteristics of apoM and its relationship to cardiovascular disease.

Objective To investigate uncertainty in illness of family members of patients with malignant tumor,to explore the factors that affect uncertainty in illness of family members of patients with malignant tumor,and to provide clinical basis for clinical doctors and nurses implementing effective interventions for their patients.Methods Questionnaires were conduted to investigate uncertainty in illness of family members of patients with malignant tumor and explore the related factors.The measurements included three parts,Chinese version of Mishel uncertainty in illness scale for family member,self-designed questionnaire about family general condition,patients disease information.Results The total score of uncertainty in illness was 82.71±9.93,more than 50 ％ (75 score) of the highest PPUS-FM score.There were statistical significances of uncertainty in illness in education (F =8.06,P ＜ 0.05),family income (F=3.14,P ＜ 0.05),residence place (F =3.99,P ＜ 0.05) and frequency of hospitalization (F =4.85,P ＜ 0.05).Conclusion Family members of patients with malignant tumor have a higher level of uncertainty in illness.Education,family income,residence place and frequency of hospitalization have a certain effect on uncertainty in illness of family members of patients with malignant tumor.

Cirrhotic portal hypertension can lead to changes in the cardiovascular system,including hyperdynamic circulation,increased cardiac output,increased splanchnic blood flow,increased heart rate,peripheral vasodilatation,decreased resistance,and a drop in blood pressure.This hemodynamic disorder not only plays an important role in the maintenance of portal hypertension,but also causes retention of sodium and water,ascites,hepatorenal syndrome,and hepatopulmonary syndrome.Recently,there is an increased interest in clinical research reports that suggest treatments for cirrhotic portal hypertension.Therapies involve internal medicine,interventional treatment,and surgery for preventing and controlling upper gastrointestinal hemorrhage,splenomegaly,hypersplenism,and other symptoms.Various treatments had some positive effects on the hyperdynamic circulatory state of the cardiovascular system.

Objective To understand the prevalence of internet addiction disorder(IAD)and explore its relationship with suicidal tendency of undergraduates.Methods A total of 1517 undergraduates were investigated by using Internet Addiction Scale(IAS),Beck Hopelessness Scale(BHS)and self-made questionnaire.Results The prevalence of lAD was 14.8％.Males,single child,and those at the second grade,with poor performance or higher family income were at a higher risk of internet addiction(P ＜ 0.01).There was significantly positive correlation between internet addiction and suicidal tendency in undergraduates(x2 =76.30,P ＜ 0.01,r =0.40).The risk of suicidal tendency was significantly increased in the high internet addiction score group(OR =12.29,95 ％ CI 6.33 to 23.84).Conclusion Higher prevalence of IAD was found in the undergraduates,which could contribute to the increasing suicide.
