Vascular or endoluminal stent is a stent implanted in the lesion site to support stenosis vessels based on luminal balloon expansion,to reduce vascular elasticity recoil and remoulding,and maintain blood flow patent.Some stents can also prevent vascular restenosis.Stent size,surface coverage,radial supporting,extensibility,longitudinal recoil,fatigue test,material composition,corrosion-resistance,coagulation,surface roughness and biocompatibility(blood compatibility) are performance parameters to evaluate the stents.Vascular or endoluminal stent has been widely used in arterial and venous systems and non-vessel luminal systems.The incidence of complications following stenting is 11.6%,including acute or subacute thrombogenesis,restenosis,or stent dislocation.It is commonly demonstrated that intrastent restenosis is caused by hyperblastosis.

Diarrhoea is one of the main causes of morbidity and mortality in the developing countries,it accounts for a large part of global disease burden every year.Water and sanitation are closely associated with the morbidity of diarrhea.The recent researches were reviewed in this paper,and the effect of drinking water,sanitation and hygienic knowledge on diarrhea was discussed.The incidence rate of diarrhea was likely to decrease as water supply and sanitation were improved.

AIM: To determine whether the 23 - gauge ( 23G ) vitrecomy cutter could replace scissors in conventional 20-gauge ( 20G ) pars plana vitrectomy for treating severe proliferative diabetic retinopathy ( PDR) .
METHODS:Non-comparative interventional case series. Totally 27 eyes of 27 patients with PDR stageⅥ confirmed by funduscopy and B-ultrasound scan were enrolled. They underwent 20G vitrectomy, in which 23G vitrectomy cutter replaced scissors to remove neuvascular membrane. All 27 eyes received complete panretinal photocoagulation, 17 eyes received no tamponade, 6 eyes were 12% C3 F8 tamponade, 4 eyes were filled with silicone oil. The follow up time was 3mo. The operation duration time, iatrogenic retinal tear and retinal bleeding need electric coagulation, best corrected visual acuity ( BCVA) , retinal reattachment were analyzed.
RESULTS: The operative time was 35- 120 ( average 79-19±29. 82) min; intraoperative iatrogenic retinal breaks were detected in 2 eyes (7%). At the end of 3mo follow up, BCVA>0. 1 were in 9 eyes, from 0. 05-0. 1 in 10 eyes,<0. 05 in 8 eyes. Retinal reattached in 25 eyes (93%), still detached in other 2 eyes with silicone oil.
CONCLUSION: The 23G vitrectomy cutter could replace scissors in conventional 20G pars plana vitrectomy for treating severe PDR.

Objective To establish the quality standard for Zaizao Nongsuo Wan. Methods Artificial Calculus Bovis, Radix Paeoniae Rubra, Rhizoma Coptidis and Herba Ephedrae were identified by TLC. The content of Muscone was determined by GC. Results Under the selected conditions, the clear and distinguished spots were obtained. For content determination, the linear range of Muscone was 0.101 2 ? g～ 1.012 ? g, r=0.999 9, the average recovery was 99.11 % ( n=5) and RSD was 3.59 % . Conclusion The methods are proved to be simple, specialization with a good reproducibility, and can be used to control the quality of Zaizao Nongsuo Wan.

OBJECTIVETo explore the alterations of after depolarization and triggered activity in myocardiac muscle during progression of mouse aortic stenosis.

METHODSAfter the establishment of mouse aortic stenosis model, the heart was collected and intracellular potential was recorded using standard glass microelectrode. After the recording, the action potential (AP), early after depolarization (EAD), delayed after depolarization (DAD) in papillary muscles were analysed.

RESULTS(1) Compared with that of time-matched control mice, there were no changes of the action potoutial duration at 90% repolarization(APD90) in model mice at 2 and 5 weeks, whereas the APD90 was progressively prolonged at 9 and 13 weeks. (2) During the 30 minites of the experiment, spontaneous EADs and DADs were frequently present in medel mice at 9 and 13 weeks, were not in control and model mice at 2 and 5 weeks. (3) Compared with those of control group, EADs and DADs triggered by hypokalaemia or isoproterenol were increased significantly. The incidence rate of triggering EADs and DADs was progressively increased over time.

CONCLUSIONEAD, DAD and trigger activities increase gradually during the process of aortic stenosis, and it suggests that the myocardium electrical-instability is markedly increased in the insult hearts.

OBJECTIVETo find the characteristic parameters from electrocardiogram (ECG) which is most related to pathological progress, surface ECG was performed in mice at 2, 5, 9 and 13 week post surgery.

METHODSElectrocardiogram recordings: The mice were anaesthetized with tribromoethanol (250 mg/kg, i.p.). Lead II surface ECG were acquired by using the Biopac System MP150 at a rate of 5 kHz.

RESULTS(1) No arrhythmia was observed in Sham and 2-week Band mice. Spontaneous arrhythmias were observed in ECG recordings, with an incidence of 15%, 28% and 63% in 5-, 9- and 13-week Band mice, respectively. Tachyarrhythmias, such as frequent premature ventricular extrasystole, bigeminy, trigeminy, and paroxysmal tachycardia were found. (2) Analysis of ECG recordings revealed a significant prolongation of QT and QTc intervals. Compared with age-matched Sham mice, the increment in QT and QTc intervals was 20.4%, 32.7%, 49.7%, 61.0% and 27.1%, 32.1%, 43.9%, 59.1% at 2, 5, 9 and 13 week, respectively (P < 0.01). (3) The characteristic change in electrocardiogram was on the J wave. The amplitude of J wave was upward in Sham mice, and it was significantly flattened or inverted in Band mice. (4) Except that RR interval at 2 week showed a slight decrease, there was no significant change in PR interval and RR interval in Band mice.

CONCLUSIONIn the present study, we found that the increase incidence of spontaneous arrhythmias, prologation of QT interval and changes in the amplitude of the J wave in the surface ECG during progression of mouse cardiac hypertrophy and failure, and the progressive pattern indicated that a gradual aggravation of the ventricular repolarization delay in this mouse model.

Bone metastasis is the most common diagnosis considered for lytic lesions in the bone. Parathyroid cancer presenting as overt bone disease with diffuse lytic lesions secondary to untreated hyperparathyroidism (HPT) is a rare entity nowadays. We report the case of a 50-year-old Chinese lady who presented with diffuse bone lesions consistent with Brown tumours, vertebral body collapse and hypercalcaemia mimicking bone metastasis and was later diagnosed with parathyroid cancer.
