ABSTRACT

Massive blood loss and blood transfusion constantly occur in liver transplantation. Over the past two decades, the amount of blood transfusion during the perioperative period has been decreased dramatically along with the continual maturity of liver transplantation techniques. The goal of liver transplantation without blood transfusion has been achieved. Since bleeding and blood transfusion are correlated with poor prognosis after liver transplantation, reducing bleeding and unnecessary blood transfusion has become the key objective during perioperative period of liver transplantation. In this article, adverse effects of allogeneic blood transfusion during perioperative period of liver transplantation, coagulation function monitoring of patients with end-stage liver disease, blood transfusion management of liver transplant recipients and the strategies of reducing perioperative blood transfusion in liver transplantation were summarized, aiming to provide reference for reducing the requirement of blood transfusion during perioperative period of liver transplantation.

ABSTRACT

This study integrates metabolomics and network pharmacology techniques to systematically analyze the possible mechanism of Pudilan Xiaoyan oral liquid (PDL) in the treatment of acute respiratory infections. GC-MS metabolomics analysis found 8 endogenous metabolites, 3-phosphoglycerate, α-aminoadipate, D-ribulose-5-phosphate, β-mannosylglyceric acid, D-fructose, urea, D-maltose and ornithine in the serum of mice with acute respiratory infection induced by LPS; these substances can be used as biomarkers for PDL use in the treatment of acute respiratory infections. Biological network studies revealed 10 potential targets for intervention by PDL in the glycolysis and pentose phosphate pathways, including GPI, G6PD, H6PD, PFKM, TALDO1, TKT, GAPDH, HK1, PKLR and TPI1. All animal experiments were carried out with approval of the Animal Ethics Committee of Nanjing University of Chinese Medicine. Our findings indicate that the strategy of combining metabolomics and network analysis can provide information on the possible mechanism of PDL in acute respiratory infections, and reveal that PDL may ameliorate the pathological process of acute respiratory infections by regulating disordered metabolic pathways.

ABSTRACT

Purpose@#The aim of this study was to compare the efficacy of liver transplantation (LT) and liver resection (LR) for hepatocellular carcinoma (HCC) patients with portal vein tumor thrombus (PVTT) and to investigate risk factors affecting prognosis. @*Materials and Methods@#A total of 94 HCC patients with PVTT type I (segmental PVTT) and PVTT type II (lobar PVTT) were involved and divided into LR (n=47) and LT groups (n=47). Recurrence-free survival (RFS) and overall survival (OS) were compared before and after inverse probability of treatment weighting (IPTW). Prognostic factors for RFS and OS were explored. @*Results@#Two treatment groups were well-balanced using IPTW. In the entire cohort, LT provided a better prognosis than LR. Among patients with PVTT type I, RFS was better with LT (p=0.039); OS was not different significantly between LT and LR (p=0.093). In subgroup analysis of PVTT type I patients with α-fetoprotein (AFP) levels >200 ng/mL, LT elicited significantly longer median RFS (18.0 months vs. 2.1 months, p=0.022) and relatively longer median OS time (23.6 months vs. 9.8 months, p=0.065). Among patients with PVTT type II, no significant differences in RFS and OS were found between LT and LR (p=0.115 and 0.335, respectively). Multivariate analyses showed treatment allocation (LR), tumor size (>5 cm), AFP and aspartate aminotransferase (AST) levels to be risk factors of RFS and treatment allocation (LR), AFP and AST as risk factors for OS. @*Conclusion@#LT appeared to afford a better prognosis for HCC with PVTT type I than LR, especially in patients with AFP levels >200 ng/mL.

ABSTRACT

We performed this study to evaluate the clinical outcomes of microdissection testicular sperm extraction-intracytoplasmic sperm injection (micro-TESE-ICSI) treatment that used fresh or cryopreserved sperm in patients with nonobstructive azoospermia (NOA). A total of 338 NOA patients with 344 consecutive cycles received treatment in the reproductive medicine center of Peking University Third Hospital in Beijing, China, from January 2014 to December 2017. Fresh oocytes and fresh sperm were used in 222 patients with 234 cycles (Group A). Fresh oocytes and cryopreserved sperm were used in 116 patients with 110 cycles (Group B). We compared patient characteristics, embryonic development, and pregnancy outcomes between Groups A and B. There was no statistical difference in the patient characteristics, and no differences were observed with fertilization or quality embryo rates between Groups A and B. The rates of clinical pregnancy and live birth were both higher for Group A than those for Group B (both P < 0.05). In conclusion, fresh testicular sperm appears to produce better ICSI outcomes than cryopreserved testicular sperm in patients with NOA.

ABSTRACT

The aim of our study was to compare the sperm retrieval rates (SRRs) and clinical outcomes of patients with different causes of azoospermia who underwent microdissection testicular sperm extraction-intracytoplasmic sperm injection (micro-TESE-ICSI). We conducted a retrospective study at the Reproductive Medicine Center of Peking University Third Hospital in Beijing, China, from January 2014 to December 2017. This study examined 769 patients with nonobstructive azoospermia who underwent 347 cycles of micro-TESE-ICSI. Patients with azoospermia were classified into Group A (Klinefelter syndrome, n = 284, 125 cycles), Group B (azoospermia Y chromosome factor c [AZFc] microdeletion, n = 91, 64 cycles), Group C (cryptorchidism, n = 52, 39 cycles), Group D (previous mumps and bilateral orchitis, n = 23, 23 cycles), and Group E (idiopathic azoospermia, n = 319, 96 cycles). Clinical characteristics, SRR, embryonic development, and pregnancy outcomes of the patients were compared between all groups. Patients in Group D had the highest and most successful SRR. The average SRR for all patients was 46.0%. The rates of clinical pregnancy, implantation, and live birth in Group D were 78.3%, 65.0%, and 74.0%, respectively, which were higher than those in all other groups (P 0.05). Patients with orchitis had the highest SRR and best clinical outcomes. Although AZFc microdeletion patients had a higher SRR, their clinical outcomes were worse.

ABSTRACT

Blunt traumatic thoracic aortic injury (BTAI) is an extremely serious medical condition with a high rate of associated mortality. Recent advances in techniques such as thoracic endovascular repair offer new opportunities to manage the critical BTAI patients in an efficacious yet less invasive manner. A 65 year-old-male suffered from multiple injuries after a fall, including BTAI in the aortic arch, which resulted in dissection of the descending thoracic-abdominal aorta and iliac artery, development of an intimal flap in the left common carotid artery, and dissection of the left subclavian artery. Based on the imaging information of this patient and our clinical experience, the combined treatment of fenestrated thoracic endovascular repair and a chimney technique was immediately planned to fully repair these dissections and moreover prevent further dissection of the branching vessels, additionally to ensure sufficient blood flow in the left subclavian artery and left common carotid artery. The intervention yielded satisfactory early outcomes. Follow-up assessment at six months reported no symptoms or complications associated with the stent-graft. Computed tomography angiography further confirmed adequate stent-graft coverage of the aortic injury.

ABSTRACT

OBJECTIVE@#To explore the genetic etiology of a child suspected for β-ketothiolase deficiency by neonatal screening.@*METHODS@#All coding exons and flanking sequences of the ACAT1 gene were subjected to targeted capture and high-throughput sequencing. Suspected variants were verified by Sanger sequencing and bioinformatic analysis.@*RESULTS@#The child was found to harbor compound heterozygous variants of the ACAT1 gene, namely c.121-3C>G and c.275G>A (p. Gly92Asp). The c.121-3C>G variant was also detected in his father and two sisters, while the c.275G>A (p. Gly92Asp) was a de novo variant. A c.334+ 172C>G (rs12226047) polymorphism was also detected in his mother and two sisters. Sanger sequencing has verified that the c.275G>A (p. Gly92Asp) and c.334+172C>G (rs12226047) variants are located on the same chromosome. Bioinformatics analysis suggested both c.121-3C>G and c.275G>A (p.G92D) variants to be damaging. Based on the American College of Medical Genetics and Genomics standards and guidelines, the c.275G>A variant of the ACAT1 gene was predicted to be pathogenic (PS2+ PM2+ PM3+ PP3+PP4), the c.121-3C>G variant to be likely pathogenic (PM2+ PM3+ PP3+PP4).@*CONCLUSION@#The c.121-3C>G and c.275G>A variants of the ACAT1 gene probably underlay the pathogenesis of the child. Above finding has enriched the variant spectrum of the ACAT1 gene.

ABSTRACT

According to the notice on revision of the instructions for traditional Chinese medicine injections(TCMIs) issued by the National Medical Products Administration(NMPA) from January 2006 to May 2020, the revised contents in the instructions for 29 varieties involved in the notice were sorted out, and the existing problems in the instructions for TCMIs were analyzed, so as to provide the basis for dynamic revision of the instructions. It was found that the revised items of instructions for 29 varieties all involved adverse reactions, contraindications and precautions, and warnings were added for 82.76% of 29 TCMIs preparations, indicating that all the revised contents were related to safety issues. In addition, 33.33% of the drugs risks mentioned in the precautions were not indicated in the adverse reactions; 82.76% instructions did not indicate drug interactions; 17.24% instructions lacked medication notes for special populations; 48.28% instructions did not indicate traditional Chinese medicine(TCM) syndromes of the main disease; 44.83% instructions did not indicate the type and stage of indication; and 86.21% instructions did not indicate the course of treatment. It could be concluded that the instructions for TCMIs have known risks of drugs that are not fully reflected in adverse reactions and the effective information is not comprehensive. The risk control measures proposed in the precautions need to have aftereffect evaluation and there is a lack of drug interactions and medications for special populations. As an important part of the full life-cycle management of drugs, the revision of instructions for TCMIs should be continuously improved to provide the basis for safe and reasonable application of TCMIs. Based on the above problems, it is proposed that the marketing license holder as the main body of the revision of instructions should actively carry out post-marketing basic and clinical research in accordance with the characteristics of TCM, combine the updated research with the guidance of TCM theory and improve the revision level of instructions for TCMIs to provide the basis for post-marketing evaluation.

ABSTRACT

With the emergence of drug resistance in Western medicine, the repeated administration of clinical first-line drugs becomes more severe. There are many factors leading to multidrug resistance(MDR), so it is very difficult to solve the problem. Since traditional Chinese medicine(TCM) has been used in the field of MDR in recent years, the research on the transporter-associated drug resistance and intervention of TCM has gradually become a hot spot. Therefore, in order to further explore the relationships among drug resistance, transporters, and TCM intervention, we review the relevant research progress in recent years and comb the achievements and limitations of this research at present. In the end, we put forward the research direction of changing body's ADME through the host's transporters and gastrointestinal flora, which provides new ideas for future research.

ABSTRACT

The rat osteoarthritis model was replicated by injection of sodium iodoacetate into the knee joint cavity, and the effects of Gancao Fuzi Decoction on rat osteoarthritis and the proteome of articular cartilage were investigated. Sixty SD rats weighing 230-250 g were randomly divided into normal group, model group, glucosamine sulfate group, and Gancao Fuzi Decoction high, medium and low dose groups. Osteoarthritis model was induced by intra-articular injection of sodium iodoacetate(3 mg on each leg) in all groups except the normal group. After modeling, each administration group was given intragastric administration for 1 month. During the administration period, joint pain test and joint width measurement were performed every week to observe the autonomous behavior of rats. Enzyme linked immunosorbent assay(ELISA) method was used to detect the contents of tumor necrosis factor-α(TNF-α), interleukin-1β(IL-1β), matrix metalloproteinase-3(MMP-3), and matrix metalloproteinase tissue inhibitor(TIMP-1) in rat joint lavage fluid. Hematoxylin-eosin(HE) staining was used to observe bone and joint morphology. Nano-LC-LTQ-Orbitrap system was used to detect arti-cular cartilage proteins. The results showed that, compared with the model group, Gancao Fuzi Decoction could significantly improve joint pain and joint swelling in osteoarthritis rats, significantly reduce the contents of TNF-α, IL-1β and MMP-3 in the joint cavity la-vage fluid, increase the content of TIMP-1, and relieve inflammatory diseases such as enlarged joint space, rough cartilage edge, different thickness of cartilage layer, and disordered arrangement of chondrocytes. After comparing the proteins between the groups, 273 differential proteins were screened out. KEGG analysis found that the above differential proteins involved 43 signaling pathways such as systemic lupus erythematosus, among which 11 signaling pathways were related to osteoarthritis. The above results indicated that Gancao Fuzi Decoction had a preventive effect on osteoarthritis, and its mechanism of action may be accomplished by regulating the protein expression of osteoarthritis-related signal pathways.

ABSTRACT

Rhei Radix et Rhizoma(RRR) is a commonly used traditional Chinese medicine, with extensive pharmacological effects and clinical applications. This paper summarized processing history evolution of RRR and its effect on chemical compositions and pharmacological effects, and provided feasible insights for further studies on the chemical compositions and pharmacological effects of RRR before and after processing. Relevant information demonstrated that RRR has a long history of processing and various methods. At pre-sent, Chinese Pharmacopoeia mainly records four processing methods: cleaning(raw RRR), wine processing(RRR stir-fried with wine), steaming processing(RRR wine steaming), fried charcoal(RRR charring). RRR has a good effect in clearing heat effect, hemostatic effect and blood promoting effect, and its main chemical components are anthraquinone/anthrones, stilbene, phenylbutanone, chromogens, flavonoids and tannin compounds. This paper reviewed the history evolution of RRR and its effect on chemical composition and pharmacological changes, and put forward further study ideas, with the aim to provide a basic reference for processing mechanism, effective material basis and clinical application of RRR.

ABSTRACT

The effect of Shouhui Tongbian Capsules(SHTB) on the endogenous metabolites of colon tissue in mice with slow transit constipation was analyzed by metabolomics methods to explore its mechanism in the treatment of constipation. ICR mice were randomly divided into normal group, model group and SHTB group according to the body weight. The mice were given diphenoxylate to establish the slow transit constipation model. Mouse carbon ink pushing rate, first defecation time and the number of defecation particles in 12 h were observed. The mouse colon tissue was separated and the mucous cells were detected by Periodic acid Schiff and Alcian blue(AB-PAS) staining. Ultra-high-performance liquid chromatography electrospray ionization orbitrap tandem mass spectrometry(UPLC-ESI-Orbitrap-MS/MS) technology was used to characterize the differences in tissue metabolism to screen out the potential different metabolites and possible metabolic pathways in colon tissue. The results indicated that SHTB could significantly shorten the first defecation time and the number of defecations, and increase the number of intestinal peristalsis and mucous cells in the colonic mucosa compared to the model mice. Metabolomics results showed that, compared with the normal group, a total of 17 potential biomarkers, including L-kynurenine, N6,N6,N6-trimethyl-L-lysine, L-formylkynurenine, N6-acetyl-L-lysine, L-phenylalanine, phenylacetaldehyde, xanthoxin, thymidine, glycyl-L-leucine, cystathionine,(R)-1-aminopropan-2-ol, deoxycytidine, gamma-glutamyl-gamma-aminobutyraldehyde, D-galactose, L-arginine, L-proline and pyruvate, were found and identified in colon tissue. Treated with SHTB, these metabolic differences tended to return to normal levels. Therefore, it could be made a conclusion that the therapeutic effect of SHTB on chronic transit constipation may be related to regulating phenylalanine metabolism, phenylalanine, tyrosine and tryptophan biosynthesis, arginine and proline metabolism, cysteine and methionine metabolism, tyrosine metabolism, arginine biosynthesis, pyruvate metabolism, glycolysis, pyrimidine metabolism, tricarboxylic acid cycle and galactose metabolism.
