Proliferation and migration of vascular smooth muscle cells (VSMC) are common pathological features of diabetic vascular complications,such as atherosclerosis and hypertension. Phenotypic modulation of VSMC is the basis for VSMC proliferation and migration. Therefore, studies on VSMC phenotypic modulation and its mechanisms in diabetes mellitus were of important significance to the prevention and therapy of diabetic vascular complications. This paper introduces VSMC phenotypic modulation and the underlying mechanisms in diabetes mellitus, and summarizes advance of studies on traditional Chinese medicine intervention upon VSMC phenotypic modulation, so as to provide reference for preventing and treating diabetic vascular complications with traditional Chinese medicines.

Objective To investigate the present situations of anticoagulant treatment of non-valvular atri-al fibrillation in order to get better guidance of the clinical anticoagulant therapy and reduce the incidence of stroke caused by atrial fibrillation. Methods The clinical data of NVAF patients hospitalized in the first affili-ated hospital of Chongqing Medical University from January 1 , 2012 to December 31 , 2014 were retrospectively reviewed and analyzed in terms of basic characteristics , medical treatment plan and INR monitoring. Results A total of 1,390 patients were enrolled, 85.97% of whom needed anticoagulant therapy and 25.18% of whom were treated with anticoagulants. For 15.71% of the NVAF patients treated with warfarin , INR met the standard during hospitalization. In the study, such factors as age, coronary heart disease, history of stroke and history of bleed-ing might affect prescription of anticoagulant drugs. Conclusion Most NVAF patients need anticoagulant thera-py, but the rate of anticoagulant therapy is lower than we expected. Among those patients treated with warfarin during hospitalization , the rate of INR meeting the standard is at a lower level. The novel oral anticoagulants are not in wide use in the clinical practice.

Objective To explore the factors which are related to the reoperation and relapse hiatus hernia in children.Methods Between Jan.2002 and May 2013,64 patients who suffered from hiatus hernia in Children's Hospital of Fudan University were divided into uneventful group (U group,n =49) and reoperation group (R group,n =15).The ages at operation,barium swallow examinations,operative procedures,findings during the operation and the followup of these two groups were reviewed.Results The average ages at operation in U group and R group were (14.70 ± 0.79) months and (13.60 ± 0.59) months,respectively.The major symptoms before the second operation in R group was vomiting(6 cases),pneumonia (4 cases) and dysphagia (2 cases).Asymptomatic recurrence was found in 3 patients.Through barium swallow examination,short esophagus was found in 10 cases in U group,while 3 cases were reported in R group.However,during the operation,the length of intra-abdominal esophagus without tension could be obtained with average (3.33 ± 0.86) cm in these short esophagus patients,which was only (3.18 ± 1.14) cm in those normal esophagus patients.There was no significant difference between the U group and R group in the width of the hiatus and the ratio of stomach above the hiatus.The length of esophagus which mobilized during operation was shorter in R group than that in U group(P =0.003).The difference of operative methods and the ratio of large hernia between these two groups could not be found.The common cause of failure in R group was herniated fundoplication (9 cases),which was followed by disputed fundoplication (4 cases),twisted fundoplication (1 case) and rupture of esophagus (1 case).The average follow up time was (8.3 ± 4.2) months in R group.Vomiting was found in 3 patients,and pneumonia was found in one case in R group after the second operation.The symptoms of these four patients were relieved half year later postoperatively.Conclusions The age,symptoms,size of the hiatus,short esophagus,and the operative methods are not related to the reoperation in hiatus hernia.But if the length of intra-abdominal esophagus without tension was not obtained enough,it may contribute to the recurrence of hiatus hernia.Wrap herniation has now become the most common mechanism of failure requiring reoperation.

Objective To summarise the experience of surgical treatment of invasive pulmonary fungal infection in patients with hematologic malignancies.Methods From Jan.2000 to Dec.2012,78 hematologic patients with invasive pulmonary fungal infections,including 49 males and 29 females with average age of 29.6 years,underwent surgical treatment.Preoperatively,all patients with 1 to 3 courses of chemotherapy had received average 4 weeks antifungal treatment.There were 58 cases received conventional open thoracic surgery and 20 cases received VATS including lobectomy,segmentectomy,wedgectomy.Results The procedures were successful,the average operation time w as(125.3 ± 35.7) min and intraoperative blood loss was(253.1 ± 42.8) nl.There were no severe postoperative complications.The main complications were excessive effusion (10.2％) and persistence airleak (7.7％).The hospital days was(7.8 ± 2.5) days,no reoperation and death case in 30 days after operation.The follow-up was from 6 to 24 months,38 cases(48.7％) received prophylaetic antifungal treatment,no ease with fungi spread and recurrence.Conclusion The surgical treatment is safe and useful for the hematologic patients with invasive pulmonary fungal infections,when internal medicine conservative treatment is invalid.

AIM: To study the clinical characteristics of corneal perforation ( CP) .
METHODS:A retrospective analysis in July 1995 to July 2010 the First Affiliated Hospital of Fujian Medical University diagnosed CP 72 patients ( 72 eyes ) , clinical characteristics of all the patients were analyzed.
RESULTS: The incidence of corneal ulcer perforation rised year by year, the morbidity of male and female was 17:7, the onset age focused on 48 years old. Of 23 industrial workers ( 32%) with clear history of trauma, pathogeny identification results:top two:fungal infection and Acanthamoeba keratitis. A using history of glucocorticoid was found in 10 cases.
CONCLUSION:There are plenty of primary causes of CP such as traumas, fungal infection, Acanthamoeba keratitis, eroded keratitis, etc. CP happens in middle-aged males in Fujian province, most traumas are the causes, the main pathogenic bacteria is fungal infection.

Objectives: To investigate the effects of adhesion and proliferation of bone mesenchymal stem cells (BMSCs) in the surface of lactic acid/glycolic acid/asparagic acid-co-polyethylene glycol PLGA-[ASP-PEG] tri-block polymer scaffolds, try to find a new biomaterial to induce seed cells in vitro for bone tissue engineering. Methods: Modified PLGA with polyethylene glycol (PEG) and asparagic acid (ASP) that has many ligands, and synthesis PLGA-[ASP-PEG] polymer material. BMSCs were cultured in PLGA-[ASP-PEG] polymer material and PLGA used as control group.

Results: BMSCs on the surface of PLGA-[ASP-PEG] polymer scaffolds are adherention to the culture flask, the number of cells is much higher than PLGA’s. The precipitation method suggest that adhesion and proliferation of BMSCs on the surface of PLGA-[ASP-PEG] is much higher than the control group(P

Wet age-related macular degeneration (AMD) is one of major causes of blindness in elder people.Intraocular injection of anti-vascular endothelial growth factor (VEGF) -A regimen has made big breakthrough for the treatment on choroidal neovascularization of wet AM D,while long-term follow-up and necessary retreatments are the key issues to remain obtained visual acuity.Multiple strategies of wet AMD have been used in following-up and retreating based on the visual acuity,optical coherence tomography (OCT),ophthalmoscope and fluorescein fundus angiography (FFA) in abroad.However,there also are major differences in the patient' s composition,treatment habits and distribution of medical sources in China from Western.So we suggest to standardize the follow-up and retreatment strategies about intravitreal injection of VEGF-A for wet AMD as to achieve a better effectiveness.OCT-guided individual follow-up and retreatment strategies should be very helpful for maintaining a long-term efficacy,minimizing the treatment time and reducing medical cost.
