Acupuncture for Smoking Cessation: A Systematic Review and Meta-Analysis of 24 Randomized Controlled Trials

Abstract: Introduction We evaluate the effectiveness and safety of transdermal acupuncture by needles for smoking cessation. Methods A literature search for randomized controlled trials (RCTs) was performed in seven electronic databases from inception to February 2017. Meta-analysis was conducted using Revman 5.3.0 software. We used either a random effects model (REM) or a fixed effects model (FEM) for pooling data according to the result of a heterogeneity test (defined as significant if I2>75%). Trial sequential analysis (TSA) was applied by TSA 0.9.5.10 Beta software. Results Twenty-four trials involving 3984 participants were included. The methodological quality was generally low. With regard to smoking abstinence, meta-analysis showed acupuncture was more effective compared to no intervention/waiting list for short-term (4 weeks) cessation (1 trial, RR=2.37, 95% 1.41, 3.97) and long-term (longer than 6 months) (2 trials, RR=2.66, 95% CI: 1.50, 4.70). Compared to acupuncture/auricular acupressure alone, acupuncture plus auricular acupressure showed more benefit for short-term cessation (3 trials, RR=1.52, 95% CI: 1.03, 2.25). Acupuncture plus auricular acupressure was more effective compared to sham acupuncture plus sham auricular acupressure for short-term cessation (3 trials, RR=2.50, 95% CI: 1.44, 4.33) and long-term (2 trials, RR=3.61, 95% CI: 1.37, 9.48). Acupuncture in combination with counseling, educational smoking cessation program or moxibustion had more benefit compared to acupuncture for short-term cessation (3 trials, RR=0.75, 95% 0.63, 0.91) and long-term (2 trials, RR=0.77, 95% CI: 0.56, 1.05), and TSA illustrated the cumulative Z-curve of this comparison for long-term across the traditional boundary of 5% significance and monitoring boundaries. No serious adverse events occurred. Conclusions Acupuncture combined with counseling, educational smoking cessation program or moxibustion was more effective than acupuncture as monotherapy with regard to long-term smoking cessation. Further, high quality trials are needed to confirm the result.

Rapid Characterization and Identification of Chemical Constituents in Gentiana radix before and after Wine-Processed by UHPLC-LTQ-Orbitrap MSn

Abstract: Gentiana radix is used in traditional Chinese medicine and has functions of clearing heat and drying dampness, as well as purging liver and gallbladder fire. A highly sensitive and effective strategy for rapid screening and identification of target constituents has been developed by using ultra high-performance liquid chromatography coupled with linear ion trap-Orbitrap mass spectrometry (UHPLC-LTQ-Orbitrap) in crude and wine-processed Gentiana radix. Based on the accurate mass measurement (<5 ppm), retention times, and MS fragmentation ions, 52 constituents were unambiguously or tentatively characterized from Gentiana radix, including 21 iridoids, 11 flavonoids, 19 xanthones, and a triterpenoid. This study demonstrated that the established method could be a rapid, effective analytical tool for screening and characterization of compounds in the complex systems of Gentiana radix. By comparing the structure and peak areas of chemical constituents in crude and wine-processed Gentiana radix, we found that some compounds in crude and wine-processed Gentiana radix were significantly different.

Genetic diversity and its conservation implications of Vitex rotundifolia (Lamiaceae) populations in East Asia.

Abstract: Vitex rotundifolia is an important coastal and medicinal plant, and is recorded in the List of the Important Wild Plants for Conservation in China and Japan. However, an effective conservation strategy is lacking. In the present study, the genetic diversity and population structure were analyzed using phylogeographical methods based on the trnH-psbA and trnG-trnS intergenic spacers of the chloroplast DNA (cpDNA) sequences from 157 individuals from 25 sampling sites for V. rotundifolia and V. trifolia plus the internal transcribed spacer (ITS) of the nuclear ribosomal DNA (nrDNA) sequences of 177 individuals from 27 sampling sites. The results showed that V. rotundifolia and V. trifolia had eight cpDNA and two nrDNA haplotypes, respectively, and the V. rotundifolia has a low level of genetic diversity (haplotype diversity hd,cp = 0.360, hd,nr = 0.440), a more pronounced genetic differentiation among populations (population differentiation at the species level (GST) = 0.201, population differentiation at the allele level (NST) = 0.462), and an insignificantly different phylogeographical structure (NST > GST, P > 0.05). In addition, haplotype network analyses indicated that V. rotundifolia and V. trifolia have distinct haplotypes. Divergence dating based on BEAST software analyses showed that most cpDNA clades diverged in the late Pleistocene era. Demographic analysis indicated that V. rotundifolia underwent a rapid demographic expansion. Some scientific strategies are suggested for resource conservation of V. rotundifolia based on its genetic diversity and population structure.

Multi gene mutation signatures in colorectal cancer patients: predict for the diagnosis, pathological classification, staging and prognosis

Abstract: Identifying gene mutation signatures will enable a better understanding for the occurrence and development of colorectal cancer (CRC), and provide some potential biomarkers for clinical practice Currently, however, there is still few effective biomarkers for early diagnosis and prognostic judgment in CRC patients The purpose was to identify novel mutation signatures for the diagnosis and prognosis of CRC Clinical information of 531 CRC patients and their sequencing data were downloaded from TCGA database (training group), and 53 clinical patients were collected and sequenced with targeted next generation sequencing (NGS) technology (validation group) The relationship between the mutation genes and the diagnosis, pathological type, stage and prognosis of CRC were compared to construct signatures for CRC, and then analyzed their relationship with RNA expression, immunocyte infiltration and tumor microenvironment (TME) Mutations of TP53, APC, KRAS, BRAF and ATM covered 9755% of TCGA population and 8302% validation patients Moreover, 5714% validation samples and 2206% TCGA samples indicated that patients with mucinous adenocarcinoma tended to have BRAF mutation, but no TP53 mutation Mutations of TP53, PIK3CA, FAT4, FMN2 and TRRAP had a remarkable difference between I-II and III-IV stage patients (P < 00001) Besides, the combination of PIK3CA, LRP1B, FAT4 and ROS1 formed signatures for the prognosis and survival of CRC patients The mutations of TP53, APC, KRAS, BRAF, ATM, PIK3CA, FAT4, FMN2, TRRAP, LRP1B, and ROS1 formed the signatures for predicting diagnosis and prognosis of CRC Among them, mutation of TP53, APC, KRAS, BRAF, ATM, PIK3CA, FAT4 and TRRAP significantly reduced their RNA expression level Stromal score, immune score and ESTIMATE score were lower in patients with TP53, APC, KRAS, PIK3CA mutation compared non-mutation patients All the 11 gene mutations affected the distributions of immune cells This study constructed gene mutation signatures for the diagnosis, treatment and prognosis in CRC, and proved that their mutations affected RNA expression levels, TME and immunocyte infiltration Our results put forward further insights into the genotype of CRC
