Objective To share the experience of surgical repair for cor triatriatum in chidren.Methods Between July 2008 and June 2013,24 children with cor triatriatum underwent surgical correction in Cardiac Center of Children's Hospital of Fudan University.The minimum age at the time of operation was 1 month,median age was 5 month;the minimum body weight at the time of operation was 3.5 kg,median body weight was 7.4 kg.Retrospectively analyzed their cardiac anatomy,clinical data,surgical procedures and follow-up data.Results Of all 24 patients,there were 4 patients diagnosed semplice cor triatriatum,and 20 patients diagnosed cor triatriatum associated with other malformation includes cardiac and non-cardiac issues.Procedures were performed on 22 patients to correct all cardiac defects in one stage.1 patient underwent surgical repair for cor triatriatum and Glenn procedure as well.1 patient,diagnosed as cor triatriatum and functional single ventricle S/P Glenn,underwent surgical repair for cor tiratriatum only.2 patients recovered from pulmonary artery hypertension crisis after operation.1 patient dead 17 days post procedure caused by respiratory failure.23 patients discharged from hospital.The longest follow-up was 73 months,at least 12 months after discharge.All alive patients were in New York Heart Association's function class Ⅰ-Ⅱ.Echo assessment revealed normal size of left atriums of almost all alive patients one year after discharge.Till April 2015,no postoperation intervention,no blood flow obstruction at level of pulmonary veins,left atrium or mitral valve.Conclusion Pediatric patients diagnosed cor tiratriatum sinister need intervention,no matter hemodynamic change occurs or not.Right time of surgery is important for successful treatment.

Objective To compare the efficacy of inhaled Iloprost and nitric oxide( NO)in infants with moderate or severe pulmonary hypertension(PH)after congenital heart disease surgery. Methods This was a prospec-tive randomized study in Children's Hospital of Fudan University from January 2011 to January 2014,including 40 in-fants who suffered from moderate to severe PH after heart surgery. Their ages ranged from 1 to 24 months. Their weight ranged from 3. 2 to 11. 0 kg. They were randomly allocated to inhale NO( NO group,n = 20)or Iloprost( Iloprost group,n = 20). Iloprost group was given Iloprost with 50 ng/(kg·min)for 10 min and then combined with NO 20 × 10 - 6 for 10 min;NO group was first given 20 × 10 - 6 of NO for 10 min,then combined with Iloprost 50 ng/(kg·min) for 10 min. Heart rate,systolic blood pressure,pulmonary artery pressure(PAP)and central venous pressure were recor-ded continuously. At the same time,the concentration of nitrogen dioxide and methemoglobin after inhaling NO was de-tected. Results Inhaled Iloprost and NO caused significant reduction in PAP(t = 4. 670,P = 0. 009;t = 3. 762,P =0. 004)and pulmonary - to - systemic pressure ratio(Pp/ Ps)(t = 16. 974,P = 0. 000;t = 9. 682,P = 0. 000)but signifi-cant increase in oxygen index separately. The combination had no additional effect compared with single application. In term of the reduction of PAP,there was no significant difference between inhaled Iloprost and NO(F = 2. 742,P =0. 129). The levels of nitrogen dioxide and methemoglobin were not above the normal limits. Conclusions Moderate to severe PH after cardiac surgery was significantly reduced by inhaled NO and Iloprost. They had similar effects. However, the combination of both vasodilators failed to prove more potent than either substance alone. Compared with the potential toxicity of NO,the individual differences and the complex transmission,Iloprost may be more reasonable and feasible for the postoperative treatment of PH.

AIM:To perform a new method for orbital implant and contracted socket through one time and its results. ·METHODS:Totally 114 patients 114 eyes, from January 2008 to June 2014, with contracted socket participated in this study. We incised the bulbar conjunctiva horizontally and excised scar tissue, then implanted the hydroxyapatite in the four extraocular muscles and tightly sutured the Tenon ' capsule. After that, we put the superior and inferior conjunctival petals backwards and sutured them to the Tenon ' s capsule. All the patients were divided into four groups according to the vertical diameter length of the conjunctival defect area:GroupⅠ:≤5mm; Group Ⅱ: 6-10mm; Group Ⅲ: 11-15mm; and Group Ⅳ: ≥16mm. These patients were followed up for 6mo to 3y to observe the conjunctival sac shaping and growth of conjunctiva. ·RESULTS:There were 64 cases in GroupⅠ, 31 cases in Group Ⅱ, 16 cases in Group Ⅲ and 3 cases in Group Ⅳ. All patients ' conjunctival defect was covered by new conjunctiva and scar tissue 4 to 6wk after surgeries. Ten cases had contracted socket; 2 cases had orbital implant exposure, requiring reoperation. Of the 114 cases, 8 had contracted socket and could use a smaller conformer, 106 could use a normal size conformer. ·CONCLUSION: When the conjunctival defect was ≤15mm, this new method can address the orbital implant and contracted socket at the same time. While it was ≥16mm, flap transplantation is necessary.

At present, most clinical thrombolytic drugs are plasminogen activators, which are highly dependent on the plasminogen level of the patient. Therefore, the efficacy of those drugs is restricted. Unlike the conventional thrombolytic plasminogen activator drugs, fibrinolytic drugs have direct fibrinolytic activity. Thus, fibrinolytic drugs can directly dissolve the thrombus, and its thromlysis efficacy is not restricted by the patients' plasminogen. This is a new type of thrombolytic drug with higher thrombolytic efficiency and safety, and has become one of the research hotspots at present. Although more and more agents that can be used as fibrinolytic drugs have been discovered, only a few of them can successfully be applied in clinical practice. The mainly underlying reason is the risk of bleeding. In this paper, based on the latest research progress of fibrinolytic drugs, the bleeding mechanisms and coping strategies of fibrinolytic drugs were systematically reviewed, five types of bleeding mechanisms of fibrinolytic drugs were summarized, and three types of coping strategies were proposed. We hope our work can provide theoretical basis for the development of safer and more efficient fibrinolytic drugs.

Good medicinal herbs, good drugs. Good evaluation method and indices are the prerequisite of good medicinal herbs. However, there exist numerous indices for quality evaluation and control in Chinese medicinal materials. However, most of these indices are non-interrelated each other, as well as having little relationship with efficiency and safety. The results of different evaluatior methods may not be consistent, even contradictory. Considering the complex material properties of Chinese medicinal materials, single method and index is difficult to objectively and comprehensively reflect the quality. Therefore, it is essential to explore the integrated evaluation methods. In this paper, oriented by the integrated evaluation strategies for traditional Chinese medicine quality, a new method called integrated quality index (IQI) by the integration of empirical evaluation, chemical evaluation, and biological evaluation was proposed. In addition, a study case of hypertoxic herb Aconitum carmichaelii Debx. was provided to explain this method in detail. The results suggested that in the view of specifications, the average weight of Jiangyou aconite was the greatest, followed by Weishan aconite, Butuo aconite, Hanzhong aconite, and Anxian aconite; from the point of chemical components, Jiangyou aconite had the characteristic with strong efficacy and weak toxicity, next was Hanzhong aconite, Butuo aconite, Weishan aconite, and Anxian aconite; taking toxicity price as the index, Hanzhong aconite and Jiangyou aconite have the lower toxicity, while Butuo aconite, Weishan aconite, and Anxian aconite have the relatively higher one. After the normalization and integration of evaluation results, we calculated the IQI value of Jiangyou aconite, Hanzhong aconite, Butuo aconite, Weishan aconite, and Anxian aconite were 0.842 +/- 0.091, 0.597 +/- 0.047, 0.442 +/- 0.033, 0.454 +/- 0.038, 0.170 +/- 0.021, respectively. The quality of Jiangyou aconite is significantly better than the others (P < 0.05) followed by Hanzhong aconite, which is consistent with the traditional understanding of genuineness. It can be concluded that IQI achieves the integrated control and evaluation for the quality of Chinese medicinal materials, and it is an exploration for building the good medicinal herbs standards. In addition, IQI provides technical supports for the geoherbalism evaluation, selective breeding, the development of precision decoction pieces, high quality and favourable price in market circulation, and rational drug use.

Quality control is one of the key scientific tissues in the modernization of traditional Chinese medicines (TCM). In order to overcome the deficiencies of assessment indexes, including little systematization and quantification, as well as loose association with clinical efficacy and dosage, a new integrated method named controllability pyramid ( CP) is first proposed in this paper. In addition, some study cases are used to explain how this model is constructed. We hope the establishment of CP could promote the clinical-orien- ted integrated innovation research of TCM, and provide control strategy and technology examples for improving the quality of Chinese medicines and clinical efficacy.
