Objective To explore the possible effect of combined treatment of zoledronic acid and doxorubicin on proliferation,invasion and adhesion of SGC7901 cell line,and potential underlying mechanisms. Methods MTT and Transwell experiments were used respectively to investigate the effect of different concentrations of zoledronic acid and doxorubicin on the proliferation,adhesion and invasion of SGC7901. The mRNA levels of MMP2, TIMP2, MMP9, ICAM1 and CD44 were quantified by real time PCR. Results Gastric cell line SGC-7901 were incubated with zoledronic acid for 48 h in different concentration of 10-6,10-5,10-4,10-3 mol/L,their inhibition rates were 4.98％,12.19％,27.34％ and 73.13％ separately,which were higher than control group (P＜0.01),and enhanced along with the dose increasing and the time extension (P＜0.05).Gastric cell line SGC-7901 was incubated with zoledronic acid 10-4 mol /L and doxorubicin 0.5 mg/L,respectively,or in combination for 2 h,4 h,6 h,and thereafter,the detected adhesion rates were 5.03％,24.38％ and 59.65％ in control group,4.40％,19.77％ and 51.22％ in zoledronic acid group,4.28％, 18.62％ and 51.02％ in doxorubicin group,4.02 ％,15.02％ and 46.95％ in combination group. The adhesion rates were reduced after incubation with different medicament concentration (P＜0.05).In the study of cell invasion,the cell numbers per high power field were:105.11 ± 10.43,98.37 ± 15.75,96.19 ± 9.24,83.02 ± 19.72 after treatment with zoledronic acid,doxorubicin or their combination at different concentrations. Compared with control, signal medicament had weak effectiveness in invasiveness in SGC-7901 (P＞ 0.05),whereas in combination group it was significantly decreased (P＜0.05).Both zoledronic acid and doxorubicin decreased the mRNA expressions of CD44,MMP2,MMP9,ICAM1 while increased TIMP2 mRNA level (P＜0.05or P＜0.01) versus control.The effect was more evident with combination treatment(P＜0.05 or P＜0.01),compared with doxorubicin group. Conclusions Both zoledronic acid and doxorubicin can inhibit the proliferation,adhesion and invasion of SGC7901. Combination treatment has additive effect.It may be related to the down-regulation of mRNA of ICAM1,MMP2,MMP9,CD44 and up-regulation of mRNA of TIMP2.

Objective To explore the prenatal genetic diagnosis for classic phenylketonuria (PKU) families.Methods Probands and their family members from three classic PKU families were analyzed by combining linkage analysis through short tandem repeats (STR) polymorphism and PCR-sequencing for the exons within mutation hot spot of phenylalanine hydroxylase gene.Results Linkage analysis found uninformative for Family 1,while 100 % confirmative information was obtained from Family 2 and 3.Sequencing showed compound heterozygous mutations of phenylalanine hydroxylase gene for all of the three probands.Five mutations were detected,namely Y166X,R243Q,R413P,EX6-96A ＞ G and IVS11-1G＞ C,and IVS11-1G ＞ C was a novel identified muntation.Information from linkage analysis and mutation screening showed clearly that the fetus of Family 1 and 2 were affected,while normal for Family 3.Conclusions For those PKU families,reliable service of prenatal genetic diagnosis could be provided by combining linkage analysis with mutation screening of phenylalanine hydroxylase gene.

OBJECTIVETo observe mainfestations of syndrome and biochemical indices of hypertensive model rats with excessive accumulation of phlegm-dampness syndrome (EAPDS), and to explore its possible pathological mechanism.

METHODSEAPDS rat model was prepared in 50 Wistar rats by feeding with high fat forage. Meanwhile, a normal control group consisting of 10 Wistar rats was set up by feeding with normal forage. After 25-week continuous feeding, 22 rats with body weight (BW) and blood pressure (BP) exceeding 25% those of the control group were selected as a model group. BW, BP, blood lipids, and related serological indicators were detected in all rats. Morphological changes of target organs were observed. mRNA expression levels of leptin receptor (LepR), Janus kinase2 (Jak2), signal transducer and activator of transcription 3 (Stat3), suppressor of cytokine signaling-3 (Socs3), angiotensin II receptor type 1 (AT1), angiotensin II receptor type 2 (AT2), phosphatidylinositol 3 kinase (P13K), serine threonine kinase (Akt), nuclear factor of kappa B (NF-κBp65), inhibitor of nuclear factor kappa-B kinase α (IKKα), NF-kappa-B inhibitor β (lKKβ), NF-kappa-B inhibitor α (IKBα), and AMP-activated protein kinase (AMPK) were detected by quantitative real-time PCR (qPCR). Expression levels of AT1 and LepR in aorta were detected by immunohistochemical assay and Western blot respectively.

RESULTSCompared with the control group, BW, BP, and blood lipids increased; serum levels of leptin (Lep) , Ang II, Hcy, ET-1, TNF-α, IL-6, and p2-MG increased, but NO decreased in the model group (P < 0.05, P < 0.01). Aortal endothelial injury and smooth muscle cell proliferation occurred in the model group, accompanied with heart and renal injury. Compared with the control group, mRNA expression levels of LepR, Jak2, Stat3, Socs3, AT1 , PI3K, Akt, NF-κB p65, IKKβ, IKBα, and AMPK in aorta were up-regulated significantly (P < 0.05), while the expression of IKKa decreased (P < 0.05). Immunohistochem- ical staining showed, brownish yellow deposit of AT1 and LepR was obviously increased, with more extensively positive distribution. Western blot results showed, as compared with the control group, protein expression levels of AT1 and LepR obviously increased in the model group (P < 0.05).

CONCLUSIONSModel rats exhibited typical syndromes of EAPDS. They put up weight with fat abdomen, gloomy hair, poor appetite, hypersomnia, lowered activities , reduced food intake, loose stool, dark red tongue, white tongue with white, thick, greasy fur. Lep could be taken as one of objective indicators for evaluating hypertension rat model with EAPDS.

Aim To study the effect of Baoxinbao film on endothelin(ET) and nitric oxide(NO) secretion in patients with stable angina pectoris(SAP).Methods 76 patients with SAP were randomly divided into two groups, with 40 cases in the baoxinbao group plastered with baoxinbao film and 36 cases in the isosorbide dinitrate group receiving isosorbide dinitrate. The levels of plasma ET and NO before and after treatment were observed. Results The concentrations of plasma ET were increased and plasma NO reduced significantly in the SAP patients respectively, as compared with those in the control group(all P

AIM: To determine the association between subfoveal choroidal thickness before therapy and therapeutic activity in diabetic macular edema.
METHODS: The current study was a retrospective study, which included 32 patients ( 32 eyes ) diagnosed with diabetic retinopathy and macular edema. All the patients were firstly treated with intravitreal injections of ranibizumab. Main outcome measures were included the subfoveal choroidal thickness, central macular thickness and best-corrected visual acuity ( BCVA) at preoperation and postoperative visit at 3mo.
RESULTS: After 3 monthly intravitreal injections of ranibizumab, the BCVA was significantly higher than that before therapy and accompanied with significantly reduced thickness of subfoveal choroid and central fovea of macula. Spearman analysis was revealed that a greater baseline subfoveal choroidal thickness was associated with a better BCVA (rs=0. 544, P=0. 036).
CONCLUSION:In the therapy of intravitreal injections of ranibizumab on diabetic macular edema, there seems to be a better BCVA in the patients with a greater baseline subfoveal choroidal thickness. Therefore, baseline subfoveal choroidal thickness may be a useful predictor for the therapy of diabetic macular edema.

Objective In patients with pulmonary atresia and intact ventricular septum ( PAIVS) without right ventricular-dependent coronaries, catheter techniques including the use of a sniff wire, lasers, and radiofrequency have been the most widely used initial therapy. However, percutaneous perforation and balloon valvuloplasty were associated with higher rate of procedural failure and serious complications. Methods We report our experience with a hybrid approach for pulmonary atresia with intact ventricular septum, combining surgery and interventional catheterization techniques. Between March 2005 and March 2010, hybrid procedure was carried out successfully in 30 newboms and infants with favorable anatomy. The age ranged from 1 day to 48 months with a mean of (4.59 ±3.21) months. The heart was exposed through median sternotomy. A pursestring suture was placed in the right ventricular outflow tract 2 cm away from the pulmonary trunk. Then a 16-gauge intravenous catheter was punctured through the right ventrical and perforated the atretic PV with the guidance of echocardiography. A guide wire was then inserted into the sheath and used to guide the balloon across the PV. Sequential dilations were performed until a full opening of the PV with the guidance of epicardial echocardiography. In patients ＜ 3 months PDA ligation was performed followed by modified Blalock-Taussig (B-T) shunt. In patients ＞ 3 months PDA ligation was not performed. A modified B-T shunt was inserted if severe systemic oxygen desaturation occurred after PDA ligation. Bidirectional Glenn shunt was performed for severe hypoplasia. Hybrid procedure was achieved in all patients. The simultaneous procedures included 25 cases of PDA ligation. 6 newborns underwent modified B-T shunt placement (3.5 to 5 mm) after pulmonary valvuloplasty and PDA ligation, and 2 patients ＞ 1 month underwent modified B-T shunt. Another 2 patients were selected for univentricular palliative surgery because of a diminutive monopartite right ventricle and bidirectional Glenn procedure was performed. No pericardial effusion or cardiac tamponade was observed in all patients. Another case without PDA ligation underwent a modified B-T shunt because of hypoxemia three days after hybrid procedure, and the rest patients were discharged without any further surgical intervention.During the follow-up period of 1.5 to 62.0 months, 5 patients died. 25 (83.3%) survived and were all in New York Heart Association functional class 1. Peripheral oxygen saturation increased from 0.73 ± 0.08 to 0.94 ± 0.04 (P ＜ 0.05). One patient remains in a single-ventricle pathway, whereas 24 patients achieved a two-ventricle circulation. Results Conclusion Perventricular balloon pulmonary valvuloplasty using a hybrid approach is a safe and feasible procedure for patients with PAIVS.
