Uveitis is a kind of inflammatory disease affected in ocular posterior segment.Uveitis sustains a long duration and causes a significant damage of visual function.It often leads to serious complications,such as cystoid macular edema (CME),cataract,glaucoma,retinal detachment and choroidal neovascularization (CNV).In the pathological process of uveitis,inflammatory factors promote the release of vascular endothelial growth factor (VEGF) through a variety of pathways.It has been verified that VEGF level is elevated in vitreous in the patients with uveiticinduced CME.Intravitreal injection of anti-VEGF drugs,including ranibizumab and bevacizumab,can improve the visual acuity in most patients with noninfectious uveitic-induced CME and CNV.However,intravitreously repeated injections of anti-VEGF drugs may be required in some patients.Intraocular injection of anti-VEGF drugs is an optional and effective way for those with persist macular edema and not being suitable for the use of corticosteroid or immunosuppressive therapy.However,anti-VEGF drugs may affect the efficacy of corticosteroid.Therefore,more clinical and basic researches are still needed.The status and progresses in the use of anti-VEGF drugs for uveitisinduced CME and CNV were reviewed.

Objective To inveatigate the effect of 15-HETE, a metabolite of arachidonic acid, on isolated hypoxic pulmonary arterial ringa ( PARs) , trying to find appropriate treatment for pulmonary hypertension and its complications during anesthesia in order to avoid hypoxemia. Methods Sixteen healthy Wistar rats of either sex weighing (230 ? 10) g were randomly divided into two groups : A control group breathing fresh air (FiO2 =21%) and B hypoxia group breathing hypoxic air (N2 = 90% , O2 = 10% ) in a hypoxic box. After breathing hypoxic air for 9 days the animals were anesthetized. Heart and lungs were immediately removed and PARs (0.5-1.0 mm in diameter and 3 mm in length) were prepared. Four PARs were prepared from each animal. The PARs were suspended in baths filled with Krebs-Hensleit (K-H) solution maintained at 37℃ and aerated with 95% O2 and 5% CO2. Preload was gradually increased to 0.3 g in 30 min. The isometric tension was measured using a four-channel force-displacement transducer. 15-HETE was added to K-H solution and the concentration was gradually increased from 10-8 to 10-6 mol?L-1 at 5 min intervals. Contractility of PARs was analyzed by a software of Medlab 6.0. Concentration-tension curve was drawn and contraction rates were calculated. 2 mmol?L-1 4-AP, 10-2 mol?L-1 TEA and 10-6 mol?L-1 GLYB were added to separate K-H solution baths and 40 min later 15-HETE was added in order to detennine the effect of difierent potassium channel blockers on contraction response of PARs to 15-HETE. Results With increasing concentration from 10-8 to 10-6 mol?L-1 , 15-HETE increased PARs tension gradually in a dose-dependent manner from 106% ?6% to 139% ? 4% in group A and from 113% ?6% to 163% ?6% in group B. The difference in PARs tension between group A and B was statistically significant (P

Objective: To observe the clinical efficacy of Jin's three-needle therapy on post-stroke cognitive impairment (PSCI) and the effect on neuroelectrophysiology (event-related potentials). Methods: A total of 60 PSCI patients were selected and divided into a treatment group and a control group according to the method of random number table, with 30 cases in each group. The patients in the control group received routine treatment while the patients in the treatment group received additional Jin's three-needle therapy. The treatment for both groups lasted four weeks. Mini-mental state examination (MMSE) and Montreal cognitive assessment (MoCA) scores as well as amplitude and latency of potential 300 (P300) were adopted to compare the between-group results before and after treatment. Results: Before treatment, there were no significant differences (all P>0.05) in MMSE and MoCA scores, P300 latency and P300 amplitude between the two groups. After 4 weeks of treatment, the MMSE and MoCA scores and P300 amplitudes were improved in both groups, and the P300 latencies became shorter. The results showed significant intra-group and between-group differences (all P<0.05). Conclusion: Based on the routine treatment, Jin's three-needle therapy is effective for PSCI. The mechanism is probably through its regulation on the patients' neuroelectrophysiology.

AIM: To investigate the effect of soybean isoflavones (SI) on ventricular remodeling induced by myocardial infarction (MI). METHODS: MI was induced by permanent ligation of the left anterior descending coronary artery (LAD) in male Sprague-Dawley (SD)rats. Rats were randomly divided into six groups: shamThree hours after the operation, the drugs or solvent were administrated ig qd for 35 d. Twenty-four hours after the last administration, heart rate (HR), left ventricular end-diastolic pressure (LVEDP), peak systolic left ventricular pressure (Peak), maximal rate of left ventricular pressure rising (+dp/dtmax), maximal rate of left ventricular pressure declining (-dp/dtmax) and myocardial maximal shortening velocity (Vmax) were measured. After above hemodynamic parameters were measured, hearts were extracted. The ratio of total ventricle weight to body weight(TVW/BW) was calculated. Myocardial collagen was shown with the collagen-specific picrosirius red stain,myocardial interstitial collagen volume fraction(ICVF), perivascular collagen volume fraction(PCVF), infarct size,septal thickness (ST) and left ventricular diameter (LVD) were measured by image analysis system. RESULTS:(31 ± 5) %, respectively, all of which were significantly smaller than that in MI group (( 38.9 ± 2.9) %, P ＜ 0.01 ).In MI group, TVW/BW, LVD, ICVF and PCVF were remarkably increased compared with those in sham group (P ＜ 0.01 ). The increased TVW/BW, LVD, ICVF and PCVF were significantly reduced by treatment with eaprats in MI group was significantly decreased than that in sham group (P ＜ 0.01 ). The reduced ST could be in-dp/dtmax and Vmax were decreased (P ＜ 0.01 ), while LVEDP was increased (P ＜ 0.01 ), significantly. The reSION: SI can improve cardiac function and ventricular remodeling induced by myocardial infarction in the rat.

AIM: To study the effect of genistein on c-myc mRNA expression induced by oxidized low density lipoprotein (ox-LDL) in human vascular endothelial cells (ECV304). METHODS: LDL were isolated from healthy human plasma by gradient ultracentrifugation and oxidized by CuSO4. ECV304 cells were exposed to ox-LDL 200 mg*L-1 in the presence or absence of genistein 100 μmol*L-1 for 1, 2, and 4 h in vitro. Northern blot was employed to measure c-myc mRNA levels of ECV304. RESULTS: In response to ox-LDL 200 mg*L-1, c-myc mRNA expression in ECV304 increased by 3 fold for 1h and 3.3 fold for 2 h and decreased below the control level at 4 h. Expressions of c-myc stimulated by ox-LDL in the presence of genistein 100 μmol*L-1 for 1 h and 2 h were separately 80 percent and 60 percent of that in the absence of genistein 100 μmol*L-1. CONCLUSION: Genistein can effectively inhibit c-myc mRNA expression in ECV304 induced by ox-LDL.

Objective To provide methodological references for laboratories to carry out newborn screening for disorders of amino acid metabolism,we compared the difference and distribution of ten amino acids including alanine (Ala),arginine (Arg),citrulline (Cit),glycine (Gly),leucine (Leu),methionine (Met),ornithine (Orn),phenylalanine (Phe),tyrosine (Tyr),and valine (Val) from newborn dried blood spots specimen using derivatization or non-derivatization as sample preparation methods.Method It is a comparative research study.A total of 4135 newborn screening dried blood spot samples for inborn errors of metabolism were collected from January to June,2012.All specimens came from neonatal screening center of shanghai children's hospital.Samples were prepared by two different techniques,the corresponding kits and the procedures were used as follows:(1) Simultaneous detection of 100 dried blood spot specimens using two methods respectively to compare the paired difference of each amino acid.(2) 2000 cases of normal newborn specimens were detected respectively to obtain the normal distribution of ten neonatal amino acids.(3) 35 specimens from patients previously diagnosed positively as inborn errors of metabolism were simultaneously detected with 7 amino acids to verify the consistency of two techniques in clinical judgment.Results The amino acid levels of normal newborns analyzed by one-sample.kolmogorovSmirnov test (Z value ranged from 1.997 to 6.229) showed a skewed distribution (P ＜ 0.01).Except for Leu and Tyr,non-derivatization techniqueshowed a lower concentration than derivatization technique,and the CVs of nine amino acids were ＜ 10％ except for Met (the CV of Met was 47.8％),and the average CV is 7.8％.Except for Met,Phe and Tyr,the levels of other 7 amino acids measured by two techniques showed no significant difference (P ＞ 0.05).According to 0.5th to 99.5th percentiles,the normal reference range for derivatization method were greater than on-derivatization method,and the average value was 25.3％.After clinic judgment,the results of the abnormal indicators of children with true metabolism disorders showed no statistically significant between two methods (P ＞ 0.05),the detection rate was 100％.Conclusions There was a slight difference between derivatization and the non-derivatization techniques in detecting multiple amino acids.The results of the abnormal indicators of amino acid metabolism disordersshow no statically significant difference between the two methods,and no difference in clinical judgment.Both methods can be used in detecting amino acid metabolism disorders in newborn screening.
