Abstract
BACKGROUND Biliary tract cancers (BTCs) are rare and highly heterogenous malignant neoplasms. Because obtaining BTC tissues is challenging, the purpose of this study was to explore the potential roles of bile as a liquid biopsy medium in patients with BTC. PATIENTS AND METHODS Sixty-nine consecutive patients with suspected BTC were prospectively enrolled in this study. Capture-based targeted sequencing was performed on tumor tissues, whole blood cells, plasma, and bile samples using a large panel consisting of 520 cancer-related genes. RESULTS Of the 28 patients enrolled in this cohort, tumor tissues were available in eight patients, and plasma and bile were available in 28 patients. Somatic mutations were detected in 100% (8/8), 71.4% (20/28), and 53.6% (15/28) of samples comprising tumor tissue DNA, bile cell-free DNA (cfDNA), and plasma cfDNA, respectively. Bile cfDNA showed a significantly higher maximum allele frequency than plasma cfDNA (P = 0.0032). There were 56.2% of somatic single-nucleotide variant (SNVs)/insertions and deletions (indels) shared between bile and plasma cfDNA. When considering the genetic profiles of tumor tissues as the gold standard, the by-variant sensitivity and positive predictive value for SNVs/indels in bile cfDNA positive for somatic mutations were both 95.5%. The overall concordance for SNVs/indels in bile was significantly higher than that in plasma (99.1% versus 78.3%, P < 0.0001). Moreover, the sensitivity of CA 19-9 combined with bile cfDNA achieved 96.4% in BTC diagnosis. CONCLUSION We demonstrated that bile cfDNA was superior to plasma cfDNA in the detection of tumor-related genomic alterations. Bile cfDNA as a minimally invasive liquid biopsy medium might be a supplemental approach to confirm BTC diagnosis.

Abstract
Objective: To explore the indications, selection, and effect of flap application in repairing scar carcinoma in the lower leg and ankle. Methods: A retrospective cohort study was conducted. From June 2008 to December 2018, six male patients with scar carcinoma in the lower leg and ankle were treated in Sun Yat-Sen Memorial Hospital of Sun Yat-Sen University, aged 48-64 years, with the area of lesion ranging from 3 cm×2 cm to 15 cm×6 cm. After extended resection, the defect area ranged from 8 cm×5 cm to 22 cm×9 cm, with tissue of tendon or bone exposed. Free anterolateral thigh perforator flap, latissimus dorsi myocutaneous flap, or pedicled sural neurovascular flap was selected to repair the wound according to the location of wound in the lower extremity, selection of operation position, the location of the anastomotic vessels in the recipient area, and whether there was good skin and soft tissue available in the lower leg. The size of flap was 11 cm×8 cm-26 cm×10 cm. The donor site of free flap or myocutaneous flap was closed directly by suturing in 5 cases, and the donor site of pedicled flap was repaired with full-thickness skin graft in 1 case. The blood supply and survival of flap, quality of skin graft survival, and complication were observed postoperatively. During the follow-up period, the recurrence and metastasis of scar carcinoma, and the appearance and function of donor and recipient sites were observed. Results: All the patients completed the operation successfully, all the transplanted flaps survived with good blood supply, and the skin graft in one donor site survived well. The wounds in the donor and recipient sites of all the patients healed well without infection, effusion, or dehiscence, etc. All the patients were followed up for 1-5 years. No local recurrence or distant metastasis of scar carcinoma was found. The quality of the transplanted flaps was good. The shape of the recipient area was quite good, and the function of the affected limb was fine. The appearance of the donor area was good without dysfunction. Conclusions: Flap transplantation is suitable for the patients with tendon and bone exposure after the excision of scar carcinoma in the lower leg and ankle. The flap can be selected according to the location of scar carcinoma, operation position, the location of anastomotic vessels in the recipient area, and whether there is good skin and soft tissue available in the lower leg. The free anterolateral thigh perforator flap or latissimus dorsi myocutaneous flap is an ideal choice for repair, which can be obtained in a large area, and the donor site can be directly sutured without affecting the function.

Abstract
Insect microbial symbioses play a critical role in insect lifecycle, and insect gut microbiome could be influenced by many factors. Studies have shown that host diet and taxonomy have a strong influence on insect gut microbial community. In this study, we performed sequencing of V3-V4 region of 16S rRNA gene to compare the composition and diversity of 12 Ensifera from 6 provinces of China. Moreover, the influences of feeding habits and taxonomic status of insects on their gut bacterial community were evaluated, which might provide reference for further application research. The results showed that Proteobacteria (45.66%), Firmicutes (34.25%) and Cyanobacteria (7.7%) were the predominant bacterial phyla in Ensifera. Moreover, the gut bacterial community composition of samples with different feeding habits was significantly different, which was irrespective of their taxa. The highest diversity of gut bacteria was found in the omnivorous Ensifera. Furthermore, common and unique bacteria with biomarkers were found based on the dietary characteristics of the samples. However, the bacterial community structure of the Ensifera samples was significantly different from that of Caelifera. Therefore, we concluded that feeding habits and taxonomic status jointly affect the gut bacterial community composition of the samples from Orthoptera. However, the influence of feeding habit dominates when taxonomy category below the suborder level. In addition, the dominant, common and unique bacterial community structure could be used to predict the contrastic feeding habits of insects belonging to Ensifera.

Abstract
Excitation functions of the Tnati(p,x)S43,47c, V48 and Cnatu(p,x)64Cu, Z62,65n reactions were measured in the energy range of 8.8-18.4 MeV by using the stacked-foil activation technique and off-line gamma spectroscopy. The irradiation was carried out at the superconducting linac of the Institute of Modern Physics, Chinese Academy of Sciences. Besides, the reliability and effectiveness of theoretical data from the TALYS code, recommended data of the International Atomic Energy Agency (IAEA) and evaluated nuclear data of the ENDF/B-VIII.0, JENDL-4.0/HE and PADF-2007 libraries were evaluated and verified by comparing with experimental data. Our experimental results agree with most of the available literature data. TALYS-1.95 code could not reproduce, in most cases, the experimental data. Evaluated nuclear data from the ENDF/B-VIII.0, JENDL-4.0/HE and PADF-2007 libraries are able to reproduce, in most cases, the experimental data trend. Recommended data of the IAEA are in good consistent with our work and most of the available literature data.

Abstract
OBJECTIVE To investigate the sensitivity of adult worms of filial generations from praziquantel-resistant and -sensitive Schistosoma japonicum mixed infections to praziquantel. METHODS Mice were infected with the cercariae of an experimentally generated praziquantel-resistant S. japonicum isolate [median effective dose (ED50) = 277.4 mg/kg] and a laboratory-maintained praziquantel-sensitive S. japonicum isolate (ED50 = 99.6 mg/kg) at a mixture ratio of 1:1 and 2:1, which was maintained in the laboratory via the mouse-snail cycle for 8 generations. Then, mice were infected with the cercariae of the 8th filial-generation parasite, and grouped 35 days post-infection. Mice in the 5 treatment groups were given praziquantel treatment by gavage at a single oral dose of 37.5, 75, 150, 300 mg/kg and 600 mg/kg, while animals in the control group was administered orally with 2.5% cremophor EL. All mice were sacrificed 14 days post-treatment and adult worms were collected by perfusion of the portal vein. The worm burden reductions and praziquantel ED50 values were calculated. The praziquantel-resistant S. japonicum isolate generated from experimental induction with 12 rounds of praziquantel treatment with sub-curative doses was maintained in the laboratory via the mouse-snail cycle, and mice were infected with the cercariae of the 8th filial-generation parasite. The praziquantel ED50 value against the 8th filial-generation adults was measured. RESULTS After mice were infected with the mixture of cercariae of PZQ-resistant and -sensitive S. japonicum isolates at a ratio of 1:1, the praziquantel ED50 was 135.2 mg/kg against the adults of the 8th filial-generation parasite. After mice were infected with the mixture of cercariae of PZQ-resistant and -sensitive S. japonicum isolates at a ratio of 2:1, the praziquantel ED50 was 129.2 mg/kg against the adults of the 8th filial-generation parasite. In addition, the praziquantel ED50 was 208.4 mg/kg against the adults of the 8th filial-generation S. japonicum without the selection pressure of praziquantel. CONCLUSIONS Compared with the experimentally induced praziquantel-resistant S. japonicum isolate, the adult worms of the filial-generation S. japonicum show a reduced sensitivity to praziquantel in the same host following infection with the mixture of cercariae of praziquantel-resistant and -sensitive S. japonicum isolates. The adult worms of the filial generation of the praziquantel-resistant S. japonicum isolate without the selection pressure of praziquantel may still maintain the resistance to praziquantel.

Abstract
OBJECTIVE To explore the effects of micro ribonucleic acid-129-2 (miR-129-2) on proliferation and migration of liver cancer cells and its possible mechanism. PATIENTS AND METHODS The expression level of miR-129-2 was measured in liver cancer tissues and adjacent tissues from patients with liver cancer. Its level in liver cancer HepG2 cells and normal liver cells L-02 was also detected via quantitative polymerase chain reaction (qPCR). MiR-192-2 overexpression model was established in the HepG2 cell line. The proliferation and apoptosis levels of cells were determined by methyl thiazolyl tetrazolium (MTT) assay and flow cytometry, respectively. Wound healing assay was performed to detect the migration ability of cells. The expressions level of genes in the Wnt signaling pathway were measured through Western blotting. Xenograft tumor model was conducted in nude mice for exploring the in vivo effects of miR-129-2 on liver cancer growth. RESULTS The expression level of miR-129-2 was significantly lower in liver cancer tissues than that in adjacent tissues (p<0.01), and it was overtly lower in HepG2 cells than that in L-02 cells (p<0.01). Overexpression of miR-129-2 weakened proliferation and migration abilities of liver cancer cells (p<0.01), and evidently increased apoptosis level (p<0.01). Sex-determining region Y-related HMG-box 4 (Sox4) and matrix metalloproteinase-2 (MMP-2) were downregulated, while phosphorylated glycogen synthase kinase-3β (p-GSK3β) was upregulated in liver cancer cells overexpressing miR-129-2. Besides, the weight and volume of tumors in nude mice bearing liver cancer were significantly smaller after overexpression of miR-129-2. CONCLUSIONS MiR-129-2 weakens proliferation and migration and stimulates apoptosis in liver cancer cells mainly by downregulating Sox4 and inactivating the Wnt signaling pathway.

Abstract
AIMS With a goal to identify specific essential oils that can control postharvest Rhizopus rot on strawberry and peach fruits, we performed screening for 26 essential oils based on their antifungal activity against Rhizopus stolonifer in vitro and investigated the underlying mechanism. METHODS AND RESULTS Mentha spicata (Ms), Mentha piperita (Mp), Thymus vulgaris CT carvacrol (Tc) and Thymus vulgaris CT thymol (Tt) exhibited strong inhibition on R. stolonifer growth in the screening. These essential oils increased plasma membrane permeability of R. stolonifer and resulted in the outflow of intercellular electrolyte, nucleic acid, protein and soluble sugar. Morphology of R. stolonifer mycelia was greatly altered by these essential oils. Hyphae treated by these essential oils exhibited high accumulation of superoxide anion and malonaldehyde. Combination of these essential oils in commercial package reduced Rhizopus rot on strawberry and peach fruits, with Mp showing the strongest efficiency. CONCLUSION Ms, Mp, Tc and Tt essential oils inhibited R. stolonifer growth by targeting its plasma membrane and reduced Rhizopus rot on strawberry and peach fruits. SIGNIFICANCE AND IMPACT OF THE STUDY This study provides potential applications of natural plant extract, as alternatives to tradition fungicides, to control postharvest decay on fruits and vegetables.

Abstract
This paper describes eight new cave-dwelling species of the genus Tachycines from Guizhou, Hunan, Guangxi and Sichuan, i.e. Tachycines (Gymnaeta) liboensis sp. nov., Tachycines (Gymnaeta) bifolius sp. nov., Tachycines (Gymnaeta) tuberus sp. nov., Tachycines (Gymnaeta) paradoxus sp. nov., Tachycines (Gymnaeta) umbellus sp. nov., Tachycines (Gymnaeta) nulliscleritus sp. nov., Tachycines (Gymnaeta) taenus sp. nov. and Tachycines (Gymnaeta) latiliconcavus sp. nov. The females of T. (G.) ferecaecus (Gorochov, Rampini Di Russo, 2006) and T. (G.) proximus (Gorochov, Rampini Di Russo, 2006) are first recorded. Moreover, we consider T. (G.) aspes (Rampini Di Russo, 2008) as a valid species instead of a synonym of T. (G.) proximus (Gorochov, Rampini Di Russo, 2006) according to obviously different reduction of fastigium verticis and eyes, higher number of spines on the hind tibia and the shape of male genitalia. Furthermore, Eutachycines crenatus (Gorochov, Rampini Di Russo, 2006) should be retransferred to the subgenus Tachycines (Gymnaeta) due to the diagnosis of genus Eutachycines: dorsal sclerite of male genitalia with a protuberance in the upper part. Therefore, it should still belong to the subgenus Tachycines (Gymnaeta). In addition, morphological photographs of the eight new species and five known species are provided, including eyeless species.

Abstract
Objective: To explore the relationship between elevation of brachial pulse pressure and coronary heart disease in different genders. Methods: A total of 5 116 inpatients with suspected stable coronary heart disease were consecutively enrolled from December 2011 to June 2017 in the Affiliated Hospital of Chengde Medical College, and divided into coronary heart disease group (n=3 694) and non-coronary heart disease group (n=1 422). The clinical data of all inpatients were collected. A binary logistic regression model of coronary heart disease in different genders were separately established. Results: The morbidity of hypertension, dyslipidemia, type 2 diabetes, ischemic stroke and elevated pulse pressure were all higher in the coronary heart disease group than those in the non-coronary heart disease group (all P<0.05). The area under curve (AUC) of pulse pressure in the male group was 0.540, with an optimal diagnostic threshold of 50 mmHg. The AUC of pulse pressure in the female group was 0.612, with an optimal diagnostic threshold of 60 mmHg. Besides hypertension, type 2 diabetes, increase of low-density lipoprotein cholesterol, ischemic stroke, smoking, and aging, elevated pulse pressure was also an independent risk factor for coronary heart disease in both male and female groups (all P<0.05). Additionally, the risk of elevated pulse pressure for coronary heart disease was higher in female group than that of male group (odds ratio (OR): 1.741 vs 1.284, P<0.05). Conclusion: Elevated pulse pressure may be a new risk factor for coronary heart disease, and its risk for coronary heart disease is higher in women than in men.

This paper provides the first description of a female of Shoveliteratura triangula Shi, Bian Change, 2011, as well as the complete mitogenome sequence using next-generation sequencing (NGS) technology. The length of the entire mitogenome was 16,152 bp and contained the typical gene arrangement, base composition, and codon usage found in other related species. The overall base composition exhibited a clear anti-G (10.8%) and AT bias (70.5%). The third codon positions in all protein-coding genes (PCGs) displayed high AT-content values (81.4%) in contrast to lower values of 64.2%/64.5% in the first/second positions. Two tandem repeats, 2.49 repeats of 112 bp and 3.65 repeats of 201 bp, contributed 1013 bp to the length of the S. triangula control region (CR). A T-stretch as a recognition sequence of the replication origin and more than one distinct tandem repeat in the CR were common in the Tettigoniidae mitogenomes. Both the maximum likelihood (ML) and Bayesian inference (BI) analyses supported each subfamily of the Tettigoniidae as a monophyletic group. The relationships of the subfamilies were as follows: (Lipotactinae (Hexacentrinae (Conocephalinae (Meconematinae (Bradyporinae, Tettigoniinae))))). The newly sequenced species S. triangula was most closely related to Pseudokuzicus pieli.

Abstract
Background and Purpose—
The role of dual-antiplatelet therapy with clopidogrel plus aspirin has been demonstrated to substantially decrease the risk of recurrent stroke among patients with minor stroke and transient ischemic attack. We aimed to determine whether the efficacy of clopidogrel-aspirin therapy among patients with minor stroke / transient ischemic attack was influenced by the stratification of
CYP2C19
genotype and body mass index (BMI).
Methods—
CYP2C19
loss-of-function allele (LoFA) carriers were defined as patients with either LoFA of *2 or *3. Low/normal weight and overweight/obesity was defined as BMI <25 and ≥25 kg/m
2
, respectively. Primary outcome was defined as stroke recurrence at 3 months.
Results—
In a total of 2933 patients, there were 1726 (58.8%) LoFA carriers and 1275 (43.5%) patients with overweight/obesity (BMI ≥25 kg/m
2
). Stratified analyses by LoFA carrying status and BMI, hazard ratios (hazard ratios 95% CIs) of the clopidogrel-aspirin therapy for stroke recurrence were 0.90 (0.60–1.36), 0.87 (0.56–1.35), 0.65 (0.39–1.09), and 0.40 (0.22–0.71) among subgroups of LoFA carriers with overweight/obesity, LoFA carriers with low/normal weight, LoFA noncarriers with overweight/obesity, and LoFA noncarriers with low/normal weight, respectively, with
P
=0.049 for interaction.
Conclusions—
Efficacy of clopidogrel-aspirin therapy in reducing the risk of stroke recurrence is not present in
CYP2C19
LoFA noncarriers with overweight/obesity. Our study suggests that BMI significantly influences the correlation between
CYP2C19
genotype and efficacy of clopidogrel-aspirin therapy.

Piperine, a functional food alkaloid, exhibits inhibitory potential against TNBS-induced colitis via the inhibition of IκB-α/NF-κB and induces tight junction protein (claudin-1, occludin, and ZO-1) signaling pathway in experimental mice.

Abstract
BACKGROUND Inflammatory bowel disease is a chronic immunoinflammatory disease of the gastrointestinal tract. Piperine, an alkaloid, has been reported to possess antioxidant, anti-inflammatory, antiapoptotic, and antiulcer potential. AIM To elucidate the plausible mechanisms of action of piperine on experimental trinitrobenzenesufonic acid (TNBS)-induced colitis by assessing various biochemical, molecular, histological, and ultrastructural modifications. METHODS Colitis was induced in male Sprague-Dawley rats via intrarectal instillation of TNBS. Then, the rats were treated with piperine (10, 20, and 40 mg/kg, p.o.) for 14 days. RESULTS TNBS induced significant (p < 0.05) colonic damage, which was assessed by disease activity index, macroscopic score, and stool consistency. The administration of piperine (20 and 40 mg/kg) significantly inhibited (p < 0.05) these damages. Treatments with piperine (20 and 40 mg/kg) notably inhibited (p < 0.05) the TNBS-induced elevation of oxido-nitrosative stress (superoxide dismutase, glutathione, malondialdehyde, and nitric oxide), 5-hydroxytryptamine, and hydroxyproline content in the colon. Furthermore, colonic inducible nitric oxide synthase (iNOs), tumor necrosis factor-alpha (TNF-α), interleukin (IL)-1β, IL-6, interferon-gamma, and cyclooxygenase-2 (COX-2) messenger RNA (mRNA) expressions were upregulated after TNBS instillation and piperine (20 and 40 mg/kg) significantly attenuated (p < 0.05) these elevated mRNA expressions. TNBS decreased the expressions of tight junction (TJ) protein (claudin-1, occludin, and zonula occludens-1 (ZO-1)) and increased the expressions of proapoptotic (caspase-1) protein. These expressions were markedly inhibited (p < 0.05) by piperine treatment. Histological and ultrastructural studies of transmission electron microscopy suggested that piperine significantly ameliorated (p < 0.05) TNBS-induced colonic aberrations. CONCLUSION Piperine ameliorated the progression of TNBS-induced colitis by modulating the nuclear factor of kappa light polypeptide gene enhancer in B-cells inhibitor-alpha/nuclear factor-kappa B signaling pathway, thus inhibiting the overexpression of proinflammatory cytokines (TNF-α and IL's), COX-2, iNOs, oxido-nitrosative stress, and proapoptotic proteins (caspase-1) that may improve the expression of TJ protein (claudin-1, occludin, and ZO-1).

Abstract
AIMS To prevent the spread of brucellosis, a simple and rapid vertical flow technology (RVFT) for the detection of antibodies targeting brucellosis was developed. METHODS AND RESULTS In this study, Brucella sp. lipopolysaccharide was purified and used to detect brucellosis antibodies. Sheep IgG was used as a negative control. Colloidal gold-labeled recombinant staphylococcus aureus protein A was sprayed on a fibreglass membrane to prepare immunogold pads. Rapid vertical flow technology was used to detect Brucella in 1668 Sheep, 2743 bovine, 674 red deer and 420 human samples. The results indicated that the accuracy of this assay can reach 98%. CONCLUSIONS The established RVFT uses a single multifunctional buffer that can be used to detect antibodies in serum, plasma, whole blood and other biological samples while preserving the advantages of lateral-flow immunoassays. SIGNIFICANCE AND IMPACT OF THE STUDY This technology would be of great use in primary medical units and veterinary stations, and it is of great significance for the control of epidemic diseases.
