The paper summarized the current situation of diagnosis and treatment of pancreatic endocrine tumors (PETs)in China.In recent sixty years, we understand PETs more deeply, and have all kinds of imaging technique to localize the tumors.It makes more cases having been diagnosed.Operation is the most important and the first choice of treatment.The concept of minimal-invasion runs through the surgical procedure.Multi-model strategy is used in therapy for malignant PETs with liver metastasis.Basic research is focused in mechanism and early diagnosis and it helps the clinical practice.Specialization and co-operation are emphasized in the development of PETs diagnosis and treatment.

From April 2011 to October 2013,68 patients scheduled for complex hepatobiliary and pancreatic surgery underwent full-thickness suturing of abdominal incision with subcutaneous negative pressure drainage.There was no such complications as wound dehiscence or sinus formation.Except for 2 cases of wound infection,primary healing was achieved.Two infected cases were followed up for 1 year and there was incisional hernia.The full-thickness suturing of abdominal incision plus subcutaneous negative pressure drainage could prevent postoperative wound infection and promote wound healing.And this simple and practical approach is worthy of wider clinical application.

The theory of'preventing possible disease'in Traditional Chinese Medicine(TCM) is an important content of present theoretical and applied researches in TCM.After learning Daoxue and Chinese medicine,the author believes that ancient people give more attention to vitality than physique.Most of the diseases are caused by the injury of vitality,so the key to 'preventing possible disease'is not only conservation of the physique,but also conservation of the vitality.It is emphasized that the heart can communicate with natural pneuma,and the body can follow the qi transformation of nature when the human body is in the natural state.When one concentrates his spirit internally and keeps a sound mind,the genuine qi will come in the wake of it,and illness can be avoided.Researches on the theory of'preventing possible disease'must not ignore the apprehension and exploration of vitality.

Antiinflammatio No. 6 (AI6) is an effective anti-infective drug composed of four traditional Chinese medicines, namely, Lonicera japonica Thunb, Taraxacum mongolican I-Iand-Mazz, Isatis tinctoria L. and Houttuynia cordata Thunb. It was demonstrated in our experiments that the drug was able to enhance the oxidative burst of rat peritoneal macrophages as shown by increased production of H_2O_2 and exaggerated reduction of nitroblue tetrazolium (NBT). It seems likely that by these means AI6 could promote the bactericidal function of macrophagcs. NBT rcduction of macrophages was examined both by spectrophotometric quantification and electromicroscopic observation.

As the newest anti-vascular endothelial grown factor (VEGF) drug,alfibercept binds to all forms of VEGF-A,VEGF-B, and PIGF.So far, intravitreal injection of alfibercept has already been used to treat certain opthalmological diseases, such as neovascular age-related macular degeneration, polypoidal choroidal vasculopathy, central retinal vascular occlusion, diabetic macular edema, corneal neovascular,and retinopathy of prematurity.In this article,we contrasted alfibercept to the other anti-VEGF drugs, conducted a review of the recent research progress of alfibercept in opthalmological diseases and introduced the questions which still need to be solved and the probably research direction of alfibercept in the future.

Objective: To investigate the histological changes of rapid tooth movement in dogs treated by resistance reduction and distraction osteogenesis, aiming to establish an animal model and further to reveal the remodeling mechanism of rapid tooth movement. Methods: A total of 8 local hybrid dogs were selected as subjects for this study. The second pre-molar was extracted on both sides. The experimental side underwent alvelor surgery for resistance reduction and a home-made tooth-borne intraoral distraction device was installed for rapid tooth movement, while for the other side (control side) only tooth-borne intraoral distraction device was used for rapid tooth movement. The longest active force-delivery span was 2 weeks, followed by 6-week retention. The distance between the moved tooth and anchor unit was recorded weekly, and radiography was performed for each side before and after distraction. The surrounding tissues including periodontal ligament and alveolar bone were sectioned for histological analysis. Results: The average distance of tooth movement was 3.55 mm on the experimental side and 1.11 mm on the control side. The rate of tooth movement was notably higher (P<0.01) and no significant apical root resorption was detected by X-ray on the experimental side. The active alvelor bone remodeling was found on the tension and pressure sides. However, there was no significant difference between the experimental side and the control side after the retention period. Conclusion: The rate of orthodontic tooth movement can be accelerated through resistance reduction and periodontal distraction without any unfavorable effects but at minimal anchorage loss.

OBJECTIVE: To investigate the effect of nasal surgery alone for OSAHS using Meta-analysis. METHOD: The published articles were searched from PubMed, Chinese Biomedical Literature CD-ROM databases, China Academic Journals Full-text database. The quality of the searched original studies were assessed and the outcomes with the requirements were analyzed. RESULT: Nineteen articles and 621 cases were finally included, including 15 English literatures and 4 Chinese literatures. The results of Meta analysis showed that: (1)The weighted mean between pre-and postoperative AHI was no significantly difference [weighted mean difference (WMD) = 0. 11, 95% CI (-0. 02,0. 23), P>0. 05]. (2) The nasal surgery alone significantly reduced theEpworth sleepiness scale scores in thirteen studies [WMD=0. 94,95% CI (0. 62,1. 26), P<. 01]. CONCLUSION The meta-analyses show that nasal surgery alone can effectively improve the subjective clinical symptoms of patients with OSAHS. However, nasal surgery alone has a limited efficacy in treating OSAHS.

Since the 1960s,endovascular coil embolization has gradually become another treatment for intracranial aneurysms in addition to craniotomy clipping surgery,and in recent years,it has become the preferred method for many neurologists.However,the complexity of intracranial vascular anatomy and the diversity of intracranial aneurysm make the coil embolization alone unable to meet the needs of all intracranial aneurysms.And then some novel materials and techniques emerged,such as coated coils,balloon-assisted embolization,stent-assisted embolization,and covered stents.The principle of covered stents for the treatment of intracranial aneurysms is to place a kind of stents with bio-physical barriers into the parent arteries,while maintaining the patency of the parent artery,thus isolating aneurysms,leading to thrombogenesis inside and finally curing the lesions while maintaining the patency of parent arteries.It has huge advantage in the treatment of wide-necked,huge,dissecting and pseudo aneurysms without important adjacent branch vessels.This article reviews the application situation and the prospects of development of covered stents in the treatment of intracranial aneurysms.

Objective To investigate the relationship of the serum anti-lysosome associated membrane protein 2 (LAMP-2) antibody levels and anti-neutrophil cytoplasmic antibodies (ANCA)-associated glomerulonephritis.Methods Thirty-three patients with new onset ANCA-associated glomerulonephritis and thirty healthy controls were enrolled.ANCA detection was performed using indirect immunofluorescence (IIF).Enzyme-linked immunosorbent assay (ELISA) was used to detect myeloperoxidase (MPO),proteinase-3 (PR3) and other ANCA-associated antibodies including LAMP-2.The cut-off value of the serum anti-LAMP-2 antibody was determined by a receiver operating characteristic (ROC) curve.Results The serum levels of anti-LAMP-2 antibody in new onset ANCA-associated glomerulonephritis patients were significantly higher than remission stage ANCA-associated glomerulonephritis patients and healthy controls (P ＜ 0.05).The serum levels of anti-LAMP-2 antibody showed no visible difference between the remission ANCA-associated glomerulonephritis patients and healthy controls (P ＞ 0.05).The levels of anti-LAMP-2 antibody showed a strong positive correlation with ESR,Scr,BUN,proteinuria,crescent proportion and Birmingham vasculitis activity score (BVAS) and a negative correlation with Ccr,Hb and Alb.Conclusions Anti-LAMP-2 antibody is correlated with the activity of ANCA-associated glomerulonephritis and the severity of renal damage.It may be a useful indicator on the activity of ANCA-associated glomerulonephritis.
