With the development of medical technology and the improvement of standard living, the discovery rate haihger than before. There are different opinion in different scholar about the choice of surgical treatment. This paper summarizes the surgical treatment and operative indication of hepatic hemangioma.

Case based teaching or case discussion teaching of basic medical courses can deepen students' understanding of basic medical subjects and allow them to acquire practical and real problem solving skills while leaning the fundamental knowledge of their subjects.This paper discusses the features and advantages of case based teaching and gives a detailed discussion of an effective way to implement case based teaching by taking case based teaching of medical immunology as an example.

Marine medicine is an important part of Chinese medicine and a growth point of the development of marine economy. Current researches of marine medicine had ignored accumulated experience in clinical medicine for thousands of years of development of marine medicine and the guidance of traditional Chinese medicine (TCM) theory. In this article, we proposed a research mode of Mining experience-Clinical validation-Targets screening-Component screening-Component compatibility-Mechanism study under the guidance of the hypothesis of Nature-Effect-Material Trialism to study marine medicine. Kun Hai Jiang Xin (KHJX) Decoction is a marine formula drawn from the experience of ancient physicians by data mining techniques. Clinical study found that KHJX Decoction can significantly improve the overall clinical efficacy of chronic bronchitis with good clinical safety. Under the guidance of TCM herbal theory, object presented here is based on the work of KHJX Decoctionmining experience - clinical validation. The molecular docking method and receptor-ligand binding assay were applied to screen effective components from herbs of KHJX Decoction and the compatibility plan of effective components under the guidance of the principle of cold and heat effects compatibility. This study is of great significance to clarify the material basis and molecular mechanism of KHJX Decoction in the treatment of chronic bronchitis. It provides a new research mode for marine drug research.

Objective To observe the impact of pulse pressure (PP) and blood pressure (BP) circadian rhythm abnormality of aged hypertension patients on carotid atherosclerosis. Methods One hundred and fifty cases of elderly patients with essential hypertension based on 24 h ambulatory blood test results, according to the circadian blood pressure rates were divided into two groups,<10% in the non-dipper type hypertension group (72 cases),≥10%in the dipper type hypertension group (78 cases). Carotid ultrasound was performed to detect the extent, nature and classification of atherosclerotic plaques. The detection rate of carotid artery plaque in patients with hypertension was calculated based on their pulse pressure levels:≤60 mmHg (1 mmHg=0.133 kPa), 61~89 mmHg, ≥90 mmHg. Results Ultrasonography showed 61 cases of carotid artery plaques in the dipper type hypertension group, 20 cases were located bilaterally, 15 cases were in the right, 26 cases were in the left, the detection rate of plaque was 78%(61/78). Ultrasonography showed 68 cases of carotid artery plaques in the non-dipper type hypertension group, 38 cases were located bilaterally, 14 cases were in the right, 16 cases were in the left, the detection rate of plaque was 94%(68/72). The detection rate of plaque in the dipper type hypertension group was less than that in the non-dipper type hypertension group, the difference was statistically significant (χ2=8.07, P<0.01). There were 30 cases of hard plaque,13 cases of soft plaque, 8 cases of mixed plaque, and the plaques graded as 0, 1, 2, 3 were 17, 33, 13, 15 cases in dipper type hypertension group. There were 12 cases of hard plaque, 24 cases of soft plaque, 32 cases of mixed plaque, and the plques graded as 0, 1, 2, 3 were 6, 8, 25, 33 cases in non-dipper type hypertension group. The difference was statistically signiifcant (χ2=5.29, 8.75, both P < 0.01). Forty three patients with pulse pressure≤60 mmHg, the plaque detection rate was 72%(30/43);the pulse pressure of 65 cases was 61~89 mmHg, the plaque detection rate was 88%(57/65);42 cases with vein pressure ≥ 90 mmHg, the plaque detection rate was 98%(41/42). The difference was statistically signiifcant (χ2=11.65, P=0.00). Conclusion Pulse pressure increased and BP circadian rhythm abnormality are risk factors for the formation of carotid atherosclerosis.

Rectal carcinoid tumors are potential malignant and have been considered to be rare for a long time.But in recent years,the incidence has been increasing gradually,maybe due to the development of endoscopic technology,the widespread use of endoscopy for screening and the raising level of awareness.Because of the malignant tendency,early diagnosis and treatment are the most important things for patients.Nowadays,the misdiagnosis rate is still high and it is difficult to make differential diagnosis between benign and malignant tumors.The efficiency of chemotherapy and radiotherapy is not clear.Surgery is the only effective method,but there is no uniform standard for the choice of operation.At present,it is appropriate to consider tumor size,depth of invasion,lymph node,pathological type and other risk factors to determine a surgical modality.Colonoscopy is recognized to be the best means by follow-up and should be carried out regulady in a longer period of time.Therefore,it is important to summarize the diagnosis and treatment of rectal carcinoid.

Magnetic Resonance Imaging (MRI) can form a three-dimensional positioning anatomical imaging.By comparing the tumor volume and signal intensity changes,there is great value of MRI in the assessment of the efficacy of cervical cancer.With the development of imaging,magnetic resonance diffusion weighted imaging (DWI),magnetic resonance spectroscopy (MRS) can provide qualitative and quantitative information of the cellular level,which reflects changes in the treatment of tumor cells.Magnetic resonance imaging can predict early locally advanced cervical cancer neoadjuvant chemotherapy,thus providing an important basis for individualized treatment of patients.

Obstructive sleep apnea-hypopnea syndrome ( OSAHS) is a prevalent disorder often associated with multisystem dys-function.Available therapies are limited by either lack of long-term adherence or low response rates .Two emerging therapies hold promise in providing alternatives to patients with OSA .The first stems from the importance of the upperairway dilator muscles in main-taining pharyngeal stability .Electrical stimulation of the genioglossus muscle improves both upper-airway diameter and ameliorates pha-ryngeal obstruction .The results of phase ⅠandⅡclinical trials hold promise , but the reported improvements in the apnea-hypopnea index vary between subjects and long-term safety needs further studies .The second technology relies on creating an increased expiratory nasal resistance via a bidirectional valve designed to be worn just inside the nostrils .Initial findings of clinical trials suggest reduction in severity of sleep apnea and subjective daytime sleepiness .Considerable heterogeneity in response to the nasal device was noted de-spite the high adherence rates .It remains unclear which patients will likely benefit from these devices .

Acute megakaryoblastic leukemia(AML-M7)is a rare neoplastic hematologic disorder,the pathogenesis is not clearly.Recent research has found many eytogenetic changes in this disease;and also some genes mutation,such as GATAI,p53,RUNXI play very important roles in AMKL.The aim of this article is to review the cytogenetic and molecule mechanism of acute megakaryoblastic leukemia.
