    Abstract AbstractImpatiens yunlingensis S.X. Yu, Chang Y. Xia & J.H. Yu (Balsaminaceae), a species new to science discovered in Yunnan, China, is described and illustrated here, along with its phylogenetic position among other Impatiens species. Morphological, micro-morphological and molecular evidence is presented as an attestation of its novelty. Impatiens yunlingensis is similar to I. delavayi in having coarsely crenate leave margins, bracts in the upper part, ca. ⁴/₅ length of the pedicels, saccate lower sepal with shallowly bifid spur, linear capsules, and elliptic-oblong, tuberculate seeds, but differs from I. delavayi with lateral sepals 4 (vs. 2), lateral united petal basal lobes subtriangular (vs. dolabriform), and seeds’ surface equipped with tubercular ornamentation mostly covered with grain shaped appendages (vs. glabrous and without grain shaped appendages on the top).

    Abstract Biomimetic total syntheses of baefrutones A-D (1-4), baeckenon B (5), and frutescones A, D-F (6-9), isolated from the leaves of Baeckea frutescens, were achieved in 9, 8, and 5 steps, respectively, in moderate to good yields (72-83%). The synthetic routes feature the Michael addition, oxidative [4 + 2] cycloaddition, and water-promoted Diels-Alder click reactions as the key steps. This study helped gain thorough mechanistic insights into the biosynthetic origins and provided a facile approach for the construction of a library of natural tasmanone-based meroterpenoid analogues. Moreover, compounds 1-9 show potent inhibitory effects against S. paratyphi and/or C. albicans with MIC values of 3.125-25 μg mL

    Abstract Giant hiatal hernia (GHH) comprises 5% of hiatal hernia and is associated with significant complications. The traditional operative procedure, no matter transthoracic or transabdomen repair of giant hiatal hernia, is characteristic of more invasion and more complications. Although laparoscopic repair as a minimally invasive surgery is accepted, a part of patients can not tolerate pneumoperitoneum because of combination with cardiopulmonary diseases or severe posterior mediastinal and neck emphesema during operation. The aim of this article was to analyze our experience in gasless laparoscopic repair with abdominal wall lifting to treat the giant hiatal hernia. We performed a retrospective review of patients undergoing gasless laparoscopic repair of GHH with abdominal wall lifting from 2012 to 2015 at our institution. The GHH was defined as greater than one-third of the stomach in the chest. Gasless laparoscopic repair of GHH with abdominal wall lifting was attempted in 27 patients. Mean age was 67 years. The results showed that there were no conversions to open surgery and no intraoperative deaths. The mean duration of operation was 100 min (range: 90-130 min). One-side pleura was injured in 4 cases (14.8%). The mean postoperative length of stay was 4 days (range: 3-7 days). Median follow- up was 26 months (range: 6-38 months). Transient dysphagia for solid food occurred in three patients (11.1%), and this symptom disappeared within three months. There was one patient with recurrent hiatal hernia who was reoperated on. Two patients still complained of heartburn three months after surgery. Neither reoperation nor endoscopic treatment due to signs of postoperative esophageal stenosis was required in any patient. Totally, satisfactory outcome was reported in 88.9% patients. It was concluded that the gasless laparoscopic approach with abdominal wall lifting to the repair of GHH is feasible, safe, and effective for the patients who cannot tolerate the pneumoperitoneum.

    Abstract Cancer cells are addicted to glutamine. However, cancer cells often suffer from glutamine starvation, which largely results from the fast growth of cancer cells and the insufficient vascularization in the interior of cancer tissues. Herein, based on clinical samples, patient-derived cells (PDCs), and cell lines, it is found that liver cancer cells display stem-like characteristics upon glutamine shortage due to maintaining the stemness of tumor initiating cells (TICs) and even promoting transformation of non-TICs into stem-like cells by glutamine starvation. Increased expression of glutamine synthetase (GS) is essential for maintaining and promoting stem-like characteristics of liver cancer cells during glutamine starvation. Mechanistically, glutamine starvation activates Rictor/mTORC2 to induce HDAC3-mediated deacetylation and stabilization of GS. Rictor is significantly correlated with the expression of GS and stem marker OCT4 at tumor site, and closely correlates with poor prognosis of hepatocellular carcinomas. Inhibiting components of mTORC2-HDAC3-GS axis decrease TICs and promote xenografts regression upon glutamine-starvation therapy. Collectively, the data provides novel insights into the role of Rictor/mTORC2-HDAC3 in reprogramming glutamine metabolism to sustain stemness of cancer cells. Targeting Rictor/HDAC3 may enhance the efficacy of glutamine-starvation therapy and limit the rapid growth and malignant progression of tumors.

    Abstract Objective: To identify the precise ABO blood type subgroups with genotyping.
    Method: We screened ABO blood type from voluntary blood donors in our blood collection center. Samples were first examined with a routine serological method. Samples with ambiguous results were further examined with genotyping to identify ABO subgroups.
    Results: Two samples identified as A
    Conclusion: It may be difficult to identify non-typical AB patients with a routine serological method. Genotyping is a more precise method to identify blood subgroups.

    Abstract Objective: To study serologic and gene characteristics of the B(A) blood group of blood donation volunteers in Jilin Province, China.
    Methods: ABO subgroups were identified by standard serologic techniques in ABO typing discrepancy samples from all donors at the Jilin Blood Center (410,354 non-repeat donors). DNA (deoxyribonucleic acid) was collected from each sample and PCR (polymerase chain reaction) was used to sequence exons 6 and 7 and intron 6, part 5 from the ABO subgroup samples. PCR products were sequenced to identify ABO subgroups and the B(A) allele.
    Results: Four cases of B(A) blood type were found after sequencing, including two different alleles: B(A)02 and B(A)04. Three of the four alleles were B(A)04.
    Conclusion: Among blood donation volunteers in Jilin Province, China, B(A)04 is the most common B(A) blood group allele, followed by B(A)02. The B(A) blood group is associated with a complicated serologic phenotype and DNA detection is necessary for this atypical phenotype sample.
