Abstract
Melanosciadium is considered a monotypic genus and is also endemic to the southwest of China. No detailed phylogenetic studies or plastid genomes have been identified in Melanosciadium. In this study, the plastid genome sequence and nrDNA sequence were used for the phylogenetic analysis of Melanosciadium and its related groups. Angelica tsinlingensis was previously considered a synonym of Hansenia forbesii. Similarly, Ligusticum angelicifolium was previously thought to be the genus Angelica or Ligusticopsis. Through field observations and morphological evidence, we believe that the two species are more similar to M. pimpinelloideum in leaves, umbel rays, and fruits. Meanwhile, we found a new species from Anhui Province (eastern China) that is similar to M. pimpinelloideum and have named it M. Jinzhaiensis. We sequenced and assembled the complete plastid genomes of these species and another three Angelica species. The genome comparison results show that M. pimpinelloideum, A. tsinlingensis, Ligusticum angelicifolium, and M. jinzhaiensis have similarities to each other in the plastid genome size, gene number, and length of the LSC and IR regions; the plastid genomes of these species are distinct from those of the Angelica species. In addition, we reconstruct the phylogenetic relationships using both plastid genome sequences and nrDNA sequences. The phylogenetic analysis revealed that A. tsinlingensis, M. pimpinelloideum, L. angelicifolium, and M. jinzhaiensis are closely related to each other and form a monophyletic group with strong support within the Selineae clade. Consequently, A. tsinlingensis and L. angelicifolium should be classified as members of the genus Melanosciadium, and suitable taxonomical treatments have been proposed. Meanwhile, a comprehensive description of the new species, M. jinzhaiensis, is presented, encompassing its habitat environment and detailed morphological traits.

Abstract
Hanseniatrifoliolata Q.P.Jiang & X.J.He (Apiaceae), is described as new from Shaanxi Province, northwest China. The mericarp features of H.trifoliolata resemble H.himalayensis and H.phaea and molecular phylogenetic analyses (combining ITS and plastid genomes data) suggest that H.trifoliolata is closely related to the group formed by H.oviformis and H.forbesii. The new species H.trifoliolata has unique 3-foliolate leaves and differ from other Hansenia species in its leaves, umbel numbers and size. A comprehensive description of H.trifoliolata is provided, including habitat environment and detailed morphological traits.

Abstract
BACKGROUND The Peucedanum genus is the backbone member of Apiaceae, with many economically and medically important plants. Although the previous studies on Peucedanum provide us with a good research basis, there are still unclear phylogenetic relationships and many taxonomic problems in Peucedanum, and a robust phylogenetic framework of this genus still has not been obtained, which severely hampers the improvement and revision of taxonomic system for this genus. The plastid genomes possessing more variable characters have potential for reconstructing a robust phylogeny in plants. RESULTS In the current study, we newly sequenced and assembled seven Peucedanum plastid genomes. Together with five previously published plastid genomes of Peucedanum, we performed a comprehensively comparative analyses for this genus. Twelve Peucedanum plastomes were similar in terms of genome structure, codon bias, RNA editing sites, and SSRs, but varied in genome size, gene content and arrangement, and border of SC/IR. Fifteen mutation hotspot regions were identified among plastid genomes that can serve as candidate DNA barcodes for species identification in Peucedanum. Our phylogenetic analyses based on plastid genomes generated a phylogeny with high supports and resolutions for Peucedanum that robustly supported the non-monophyly of genus Peucedanum. CONCLUSION The plastid genomes of Peucedanum showed both conservation and diversity. The plastid genome data were efficient and powerful for improving the supports and resolutions of phylogeny for the complex Peucedanum genus. In summary, our study provides new sights into the plastid genome evolution, taxonomy, and phylogeny for Peucedanum species.

Abstract
OBJECTIVE To summarize the experience in diagnosis and treatment of arrhythmogenic right ventricular cardiomyopathy (ARVC) in children. METHODS A total of 14 children (7 females and 7 males) with ARVC were involved. The cases underwent electrocardiography, echocardiography, cardiac CT or MRI examinations. All cases were treated with sotalol or amiodarone in combination with propranolol. In 2 cases with drug-refractory ventricular extrasystoles, catheter ablation treatment was performed. In 6 cases with obvious impaired ventricular function, additional pharmacological therapy including vasodilators, diuretics, and digitalis were given. RESULTS Ventricular extrasystoles occurred in all 14 cases and ventricular tachycardia in 8 cases. Ten cases showed Epsilon wave on electrocardiography. All 14 cases had enlarged right ventricle and reduced right ventricular ejection fraction. CT or MRI examination showed right ventricular dilatation and a thinned wall of right ventricle in 10 cases. Ventricular extrasystoles or tachycardia disappeared in 7 cases and was reduced in 4 cases after treatment. The two children receiving catheter ablation treatment did not present ventricular extrasystoles or tachycardia in a 3-month follow-up. The heart function was improved in the 6 children with obvious impaired ventricular function after pharmacological therapy. CONCLUSIONS The clinical manifestations are diverse in children with ARVC. A definite diagnosis of ARVC should be based on a combination of electrocardiography and echocardiography examinations. Pharmacological therapy is effective partially. Catheter ablation treatment appears to be a promising option in patients with drug-refractory ventricular extrasystoles.

Abstract
Cytogenetic studies were performed on 44 Chinese patients with acute leukemia. A high percentage of patients (37.5%) with t(8;21), t(15;17) or 17q- (in poorly banded preparations), and abnormalities involving 11q23 were noted in 32 unselected patients with ANLL. A similar high percentage was previously reported in Japan and in South Africa but not in western countries. Data on casual or other non-occupational exposure to potentially carcinogenic agents were obtained by interview with the patients at their first presentation. Most patients with these three major chromosomal changes had a history of exposure, whereas most other patients did not (p = 0.01). Patients with ANLL-M3 were more often exposed than were the other patients (4/6 vs 8/38, p = 0.03). The only common exposure was to organophosphate insecticides. Twenty seven cases of therapy-related leukemia were collected from the Chinese medical literature, and 12 out of 22 (55%) cases in which subtypes were specified were ANLL-M3. This was significantly higher than the percentage of M3 in de novo ANLL in China and also higher than that of therapy-related leukemia from western countries. Two patients had siblings who died of leukemia at a similar age. The two patients showed inv(16) and del(6q) respectively.
