This paper introduces a statistics method for the segmentation evaluation for the head MRI. A new evaluation scheme proposed, the evaluation result is analyzed objectively by the statistic method. Genetic neural network algorithm proves with a stronger antinoise ability than other ones. The statistic method is helpful for evaluating the segmentation objectively.

This article reviewed literatures on the treatment of polypoid lesions of gallbladder(PLG) with Traditional Chinese Medicine(TCM) in recent years. The research showed that TCM has satisfied therapeutic effects on PLG, which can avoid unnecessary operation. But the systemic theoretic and experimental studies have been insufficient, and further studies are needed.

Inflammation plays a pivotal role in atherogenesis. In addition to being a potent predictive and prognostic marker for major cardiovascular events, recent evidence indicates that C-reactive protein (CRP) might directly promote atherogenesis by exerting direct effects on vascular cells. Thus, CRP will become important novel pharmaceutical targets for the treatment of atherosclerosis. This review presents an overview of the current knowledge about the pathological role of CRP in atherosclerosis initiation and progression.

The pathogenesis of diabetic retinopathy (DR) is more complex. For the upstream of traditional pathogenesis, to looking for unifying mechanism theory which proposed in foundation of common promoters and the latest view of DR may be the result of chronic inflammation. Both of them provide the basic and clinical theraby of DR with new direction. Therefore, there are many related issuess till needs to intensive study.

Objective To investigate the clinical effects of surgical treatment for varied types of cicatricial blepharon deformities. Methods Eleven patients (16 eyes) suffering from cicatricial blepharon deformities underwent surgical procedures. 4 cases (7 eyes) were treated with free skin flap transfer; 1 case with free skin flap transfer and amniotic membrane grafting, 2 cases with Z plasty; 1 case with pedicled skin flap; 1 case with orbicularis oculi musculocutaneous flap; 1 case (2 eyes) with wedged tarsal excision and blepharoplasty, and 1 case with allografe of keratoconjunctiva and reconstraction of conjunctival sac. Results All of 11 cases (16 eyes) showed satisfactory appearance and eyelid function to certain extent after operations. Conclusion The repair of skin defect and conjunctival sac integrality is the key step in correction of cicatricial blepharon deformities, which may offer good eyelid position and function.

Aphasia is one of the common neurological symptoms of stroke, which can seriously affect the social skills and self-care ability of patients, therefore it imposes a heavy burden on the family and society. In recent years, drug treatment of poststroke aphasia has received extensive attention. Some drugs that can affect monoamine, cholinergic and amino acid neurotransmitters have demonstrated a certain efficacy of poststroke aphasia. This article reviews the recent progress in research on drug treatment of poststroke aphasia.

Nasopharyngeal carcinoma(NPC)is one of the most common malignant tumors of the head and neck.The therapies for nasopharyngeal carcinoma include the following aspects:conventional radiotherapy,chemotherapy,surgery and molecular target therapy,etc.The combined chemo-radiotherapy and molecular target therapy has gradually become the hotspot therapy for NPC.

Cytochrome P450(CYP450)is the most important family of enzymes in microsomal mixedfunction oxidase,widely distributed in vivo.CYP450 is involved in the metabolism of many exogenous compounds,the generation of endogenous substances,in particularly,affecting the occurrence and development of the tumors and their drug treatment,in the fields of medical and pharmaceutical research,cytochrome P450 has been very noticeable.

ObjectiveTo analyze the clinical characteristics,effects of adjuvant therapy and influential factors of gastrointestinal stromal tumors (GIST).MethodsA retrospective and multiple factor Cox model analysis on 216 cases of primary GIST diagnosed by surgery and pathology was conducted.Results The total survival rates of patients at one to five years were 94.4 ％ (204/216),90.2 ％ (129/143),88.3 ％(68/77),87.5 ％ (35/40) and 85.0 ％ (17/20),respectively.The statistically significant prognostic factors for survival rates of patients with GIST included age,location of tumor,local or total tumor resection,rupture of tumor,adjuvant treatment,recurrence,mitotic rate,and tumor size (P ＜ 0.05).Due to those influence factors,the greater of the values,the higher of the risk of death.Among those factors,whether having grass total resection played a decisive role in the prognosis of patients with GIST.Other factors,such as sex,CD117,biopsies,endoscopic mucosal erosion,and operation cutting margin had no significant relevance with the survival rate of patients (P ＞0.05).Postoperative adjuvant therapy could significantly improve the survival rate of patients with GIST,especially for patients with high risk.ConclusionSurgical treatment should be given priority to treatment of GIST,and the choice of the surgery strategies depends mainly on the location and size of tumors.The complete resection or extensive resection could improve survival rates.Age,location,total tumor resection,rupture of tumor,adjuvant treatment,recurrence,mitotic rate,and tumor size are important factors affecting prognosis and survival rate of patients with GIST,which could guide standardized clinical treatment.
