BACKGROUND: Evidence exists that inhibition of matrix metanoproteinase-2(MMP-2) secretion in the proliferating hernangioma tissue by transfection of adenovirus-active MMP-2(Ad-aMMP-2) cDNA would become an important means for treatment of proliferating hemangioma.OBJECTIVE: To investigate the influences of Ad-aMMP-2 cDNA transfection on human proliferating hemangioma growth in nude mice.DESIGN, TIME AND SETTING: A randomized, grouping, and controlled observation was performed in West China Hospital of Sichuan University between August 2003 and September 2004.MATERIALS: Eighteen BALB/c-nu/nu nude mice, weighing approximately 20 g, were included. Cavernous hemangioma specimen pathologically confirmed as proliferating hemangioma was resected from one 52-day-old female child patient.METHODS: The freshly reseoted human proliferating hemangioma specimen was sliced into small pieces with a size of 5 mm×4 mm×3 mm and subcutaneously implanted into the back of 18 nude mice within 1 hour to develop mouse models of hemangioma.Forty-five days after hemangioma implantation, 15 successful hemangioma nude mice were treated by intratumoral administration of adenovirus green fluorescent protein (Ad-GFP1 n = 51 Ad-GFP group), adenovirus-active MMP-2 (n = 5, Ad-aMMP-2 group), or the same amount of phosphate buffered saline (PBS1 n = 51 control group). Intratumoral administration was performed once every other day, for a total of 4 times.MAIN OUTCOME MEASURES: Observation of tumor volume and compadson of tumor necrosis area among 3 groups; detection of GFP expression in nude mouse; gross, hematoxylin-eosin staining, and transmission etectron microscope observation of tumor tissue morphology; determination of MMP-2 cDNA expression and microvascular density by immunohistochemistry; and detection of growth cycle and apoptosis of tumor cells by flow cytometry.RESULTS:①Ad-aMMP-2 could inhibit hemangioma growth in vivo, without marked adverse reactions. Tumor necrosis of different degrees was found in each group, and tumor necrosis area was significantly greater in the Ad-aMMP-2 group than in the control and Ad-GFP groups (P < 0.01). ②Histological sections displayed GFP gene expression in the Ad-GFP group. ③Gross observation results revealed relatively large tumor tissue in the control and Ad-GFP groups and relatively small tumor tissue in the Ad-aMMP-2 group. Hernatoxylin-eosin staining results showed that in the control and Ad-GFP groups, endothelial cells aggregated together in strip-shaped or lump-shaped appearance, and in the Ad-aMMP-2 group, there were many necrotic loci arranging in lamellar-shape appearance. Transmission electron microscope results revealed vascular endothelial cells with normal morphology in the control group and tumor cells with apparent nucleoli in the Ad-GFP group, while in the Ad-aMMP-2 group, some vascular endothelial cells exhibited chromatin pycnosis in the nucleus, forming apoptotic bodies.④ MMP-2 expression and microvascular density were significantly reduced in the Ad-aMMP-2 group than in the Ad-GFP and control groups (P < 0.05). ⑤The percentage of tumor cells in G0/G1 phase was significantly higher (P < 0.05), while the proliferating index was significantly decreased, in the Ad-aMMP-2 group than in the Ad-GFP and control groups. The Ad-aMMP-2 group exhibited higher apoptosis rate of tumor cells (P < 0.05), as well as more markedly increasing apoptosis index, than the control and Ad-GFP groups.CONCLUSION: It is feasible to block human proliferating hemangioma growth by transfeotion of Ad-aMMP-2 cDNA. The included mechanisms are to inhibit vascular endothelial cells to secrete MMP-21 thereby leading to local ischemia.

Objective The results of repair for TOF with anomalous coronary artery(ACA) were studied to determine the incidence of coronary anomalies and evaluate surgical strategy choicesas well as postoperative outcomes.Methods From January 2008 to August 2014,1142 consecutive patients underwent repair of TOF including 44 patients with TOF and ACA:single coronary artery in 15,dual anterior descending coronary in 15,single left anterior descending coronary arising from the rightcoronary artery in 3 and the other ACA in 5.The median age was 5.7 years (range,1 month-27 years),and the median weight was 16.0 kg(range,4.5-51.0 kg).Surgical procedure was selected according to the extent of right ventricular outflow tract (RVOT) obstruction and distribution of the ACA.Results There was one operative death.No deaths during the follow-up period in the other 37 patients.Single patch techniquewasperformed in 15.RVOT residual obstruction detected in 7 who without transannular patch,and one need reoperation;Two patch technique was performed in 6,and 3 of them required an additional RV-PA(pulmonary artery) tube because of RVOT residual obstruction during the operation;Double oullet technique was in 6.No tube stenosis occurred in follow-up period time;PA translocation technique was in 11.The right PA stenosis was detected in 4;ACA was ligated and divided in 3,then RVOT reconstruction was performed.Conclusion The combination of ACA is not a contraindication to primary repair of TOF.But there are many anatomiacal variations of ACA,and the accuracy of preoperative diagnosis is low.So proper selection of surgical approach should be individualized based on the careful intraoperative identification of the distribution of the ACA as well as the location and degree of the RVOT obstruction.

Objective Retrospectively analyze primary experences of surgical correction of complicated aortic arch anomaly with autologous palmonary artery.Methods Between July 2010 and December 2012,13 cases of complicated aortic arch anomaly underwent reconstruction of aortic arch with autologous pulmonary artery.Classifications of aortic arch anomaly were interrupted aortic arch with ventricular septal defect in 4 patients,ventricular septal defect associated with coarctation in nine patients.There were 7 males and 6 females.Their age at surgeries ranged from 1 month to 16 years,and the body weight were from 3.5 kg to 52.0 kg with median weight of 12.6 kg.Cardiopulmonary bapass was estabished with dual arterial cannulations in patients with interrupted aortic arch.During cooling to deep hypothermia(rectal temperature was 18 ℃),intracardiac defects were totally corrected.Arch anomaly was reconstructed under deep hypothermia,including deep hypothermic cardiac arrest(DHCA) in 9 patients,deep hypothermia with regional perfusion in 4 patients.Anterior wall of pulmonary artery was excised in all of 13 patients.In 4 cases,the excised wall of anterior wall of pulmonary artery was sutured to form a conduit with different diameters according to the patient's bady surface area.Two ends of the conduit were anastomosed the aortic arch and desceding aorta respectively.In another 9 patients,aortic arch was augmented with tailored pulmonary artery patch in oval shape.The defect of pulmonary artery was repaired with autologous pericardial patch.Results There was only 1 death due tomutiple organ failure postoperatively.Another 12 patients survived without neurologic complications.Differences of arterial pressures between upper and lower extremeties were not monitored in all cases.During follow-up,routine echocardiogram showed satisfactory results with unobstructive blood flow at the aortic arch.Conclusion Autologous pulmonary artery can be used to relieved complicated aortic arch anomaly completely without any tension of anastomosis site and compression of left main bronchea postoperatively.More patients with long-term follow-up are necessary to draw an accurate conclusion of this technique.

Objective: To investigate the effects of trentment with hydroxythy starch(130/0.4) on the serum albumin and immunologic function in postoperative patients with obstructive jaundice.Methods: 24 patients with obstructive jaundice were randomly divided into the control group(n=12) and hydroxythy starch(130/0.4) (HS) group(n=12). The serum ALB was detected 1d, 3d, 5d, 7d after the operation,and the immunologic index were detected 1d and 7d after the operation.Results: The ALB content of control group and HS group were not significantly different in the postoperative 1d and 7 d(P>0.05) and had significant differences in the postoperative 3 d, 5 d (P<0.05).All immunologic index had no significant differences in the postoperative 1d, 7d (P>0.05).Conclusion: The ALB content of patients with obstructive jaundice may decrease postoperatively. Treatment with hydroxylthy starch(130/0.4) can alleviate the drop of the ALB content. But it has no effects on immunologic function.

Objective In order to optimize the Fontan circulation,a technique for direct total cavopulmonary connection was devised.To evaluate its surgical feasibility as well as surgical outcomes,our clinical experience was retrospectively reviewed.Methods From August 2005 to March 2012,23 consecutive patients underwent modified extracardiac Fontan operation with direct total cavopulmonary connection.Clinical profile of the patients,and procedural variables were examined and analyzed.Results All patients had adequately developed main and branch pulmonary arteries.Inferior caval vein was contralateral to the pulmonary trunk main pulmonary artery in 7 cases,ipsilateral in 8,and others in 8.There was 1 hospital death.The other 22 patients remained hemodynamically stable postoperatively.Prolonged effusions (n =13,62％) was a challenging problem.No obvious stenosis was found at the direct cavopulmonary anastomosis.Conclusion we are convinced that a direct total cavopulmonary connection is feasible in select subset of patients.This modified Fontan procedure retains the advantage of extracardiac connections together with the avoidance of prosthetic materials.

Abstract: In the present study, the compound XL-12 from our previous work was utilized as a lead compound. Through the optimization of the terminal phenyl ring, 12 target compounds were designed and synthesized. The structures of all target compounds were confirmed by 1H NMR, 13C NMR, and H RMS. In vitro enzyme activity assay showed that most compounds demonstrated significant inhibitory activity toward Bruton’s tyrosine kinase (BTK) and Janus kinase 3 (JAK3). Among them, compound I-3 exhibited moderate cell proliferation inhibitory activity toward Daudi cells and BaF3-JAK3 cells. In the evaluation of anti-inflammatory activity in vitro, compound I-3 could effectively inhibit the production of inflammatory factors IL-6; besides, it exhibited superior anti-inflammatory activity compared to ibrutinib in xylene-induced ear swelling model in mice.

This study was aimed to investigate the effects of oxaliplatin on human multiple myeloma cell line RPMI-8226 and its mechanism. The proliferation inhibitory rate of RPMI8226 cells was assayed by MTT, the morphological changes of RPMI-8226 cells were observed by inverted fluorescent microscopy and transmission electron microscopy, the apoptosis rate and the cell cycle distribution of RPMI-8226 cells were detected by flow cytometry, The effects of oxaliplatin on the expression of Bcl-2, caspase-8, caspase-3 mRNA were tested by RT-PCR, Bcl-2 protein expression of RPMI-8226 cells was analyzed by Western blot. The results showed that oxaliplatin could inhibit the proliferation of RPMI-8226 cells in time and dose-dependent manners. Cell number in oxaliplatin group was significantly less than that in control group under light microscope, and the growth arrangement was irregular, apoptotic cells could be seen. Under electron microscope, typical apoptotic morphological and ultrastructural changes could be observed. Flow cytometry results showed that oxaliplatin could induce apoptosis of RPMI-8226 cells, the difference have statistical significance (P < 0.05). Oxaliplatin mainly arrested RPMI-8226 cells in the S phase (P < 0.05). The expression of Bcl-2 mRNA did not have apparent change, while the expression of caspase-8, caspase-3 mRNA increased (P < 0.05). Western blot results suggested that the expression of Bcl-2 protein had no obvious change. It is concluded that the oxaliplatin can induce apoptosis of RPMI-8226 cells, activating the death receptor pathway and arresting cell cycle may be two of the related mechanisms, Bcl-2 gene has unobservable effects in the process of oxaliplatin-induced cell apoptosis.
