Polypoidal choroidal vasculopathy(PCV) is a common disease of the retina,the disease is more found in colored race.In China,the mainly nosogenic population is the female about 60 years old.The pathogenesis of PCV is unknown and there is no specific medicine at present.The funduscopic present is orangered lesions,bleed and exudation.Indocyanine green angiography(ICGA) could make a definite diagnosis of PCV.In recent,the main treatment of PCV includes photodynamic therapy,intravitreal anti-VEGF therapy,surgery for treatment of complications and combined therapy.We review the treatment and diagnosis of PCV,and propose the further research direction.

Objective To investigate the impact on renal fibrosis by inhibition of connective tissue growth factor( CTGF) by RNA interference in spontaneous hypertension rat( SHR) . Method Twenty SHR were randomly (random number) divided into SHR group ( n = 10) and RNAi group ( n = 10), eight Wistar-Kyoto rats were set as control. At the end of RNA interference procedure, all the rats were sacrificed and the kidneys were harvested. The mRNA and plasmosin of CTGF and fibronectin(FN) of renal tissue were extracted and measured by RT-PCR and Western Blotting. And the localization of CTGF and FN were analyzed with immunohistochernistry technique. The collagen deposition(shown as collagen volume traction, CVF) were evaluated with 0.1% sirius-picric staining, and the hydroxyproline of myocardium were detected by colorimetry. Results The mRNA and protein expression of CTGF decreased 66% and 62% in RNAi group (P < 0.01). The mRNA and protein expression of FN decreased 56% and 51% in RNAi group.The same inhibition effect was observed by hislological analysis. Immuno-histochemistry showed that CTGF localized both in renal parenchyma and renal interstitium, whereas FN majorly expressed in renal interstitium. Observation with light microscope showed that collagen deposition(CVF)decreased sharply in RNAi group versus SHR group. And the same effect was viewed in hydroxypnoline assay[SHR group: (0.596 ± 0.067) μg/mg, RNAi group: (0.368±0.084) μg/mg, P < 0.01 ] .Further study by polarized microscope displayed that RNA interference mainly suppressed type I collagen synthesis. Conclusions Targeted inhibition of CTGF by RNA interference leads significant decrease of extracellular matrix deposition in kidney. And the anti-fibrotic effect independent of lower the blood pressure. This study indicated CTGF take a key role in the development and progress of renal fibrosis.

Purpose To investigate the diagnostic and therapeutic value of vascular interventional technology dealing with acute massive gastrointestinal hemorrhage. Materials and methods 59 patients with acute massive gastrointestinal hemorrhage underwent the arteriography of mesenteric arteries and abdominal arteries. When positive signs of bleeding appeared, super-selective catheterization and embolization with micro-coil and gelfoam was applied immediately. Results Positive signs of bleeding were detected in 28 of 59 patients, among which 25 patients underwent embolization, and successful hemostasis was achieved in 21 cases with an achievement ratio of 84%. And there were 10 cases eventually turning to surgery.Conclusion Vascular interventional technology such as arteriography and embolization played an important role in diagnosis and treatment of acute massive gastrointestinal hemorrhage.

Objective To compared the clinical efficacy of laparoscopic-assisted vaginal and laparotomy in the treatment of early endometrial cancer.Methods CLinical data of 180 patients with endometrial cancer were analyzed retrospectively,which were randomly divided into two groups:The laparotomy group were underwent conventional abdominal hysterectomy and pelvic lymphadenectomy;Laparoscopic group were underwent laparoscopic-assisted vaginal hysterectomy and pelvic lymph node dissection.Operative time,blood loss,recovery time of gastrointestinal function,length of stay,the number of harvested lymph nodes,complications were compared.Results There were no significant differences in operative time,blood loss,the number of lymph nodes cleaned up between two groups(P ＞0.05).Recovery time of gastrointestinal function,and length of stay in the laparoscopic group was significantly shorter than the laparotomy group,the differences were statistically significant(t =2.898,2.564,P ＜0.05).The complication rates(11.0％ vs 19.1％) were no significant difference(P ＞ 0.05).Following up for 3 months to 27 months,recurfence rates(6.6％ vs 5.6％) and survival rates(98.9％ vs 97.8 ％) were no significant difference(all P ＞ 0.05).Conciusion The clinical efficacy of laparoscopic-assisted vaginal surgical treatment for early endornetrial cancer was significantly superior to laparotomy surgery with advantage of minimally invasive,quick recovery.

Objective To build a simulation model for outpatients queuing,using data from a general outpatient cardiovascular clinic of a general hospital in Shanghai and different rules in the process.The study employs time-interval controlled mode for appointment registration,for the purpose of analyzing characteristics of different queues.Methods Extraction of data of the clinic in a given month by means of HIS system to determine the parameters of the queuing models.Building the simulation model with Matlab to develop the plan of mixed queues and that of discrete queues,for analyzing the waiting time variations,with different number of doctors on duty and different number of appointments in one time interval.Resnlts In the Monday mornings for example,the mean waiting time of appointments or no-appointments are calculated by simulation with different queuing rules,different number of doctors on duty and different appointment quantities of one time interval.Conclusion The mean waiting times of appointments and no-appointments can be both sizably cut short by means of time-interval controlled appointment; different queuing plans are recommended for different departments; the simulation model should be further verified and optimized in practice.

Objective:Atherosclerosis of the carotid artery is the main cause and risk factor of ischemic cerebral infarction.We aim to evaluate the relation between acute ischemic cerebral infarction and the carotid atherosclerosis plaque.Methods: The distribution,shape,number and echoic features of the carotid atherosclerosis plaques confirmed by MRI diffusion-weighted imaging(DWI) were analyzed by color Doppler ultrasonography in 90 patients with acute ischemic cerebral infarction(Group A) and 82 controls(Group B).Results: The positive rate of acute cerebral ischemic infarction was significantly higher in Group A(76.7%) than in Group B(32.9%,P
