Abstract
Myotonia congenita and hypokalemic periodic paralysis type 2 are both rare genetic channelopathies caused by mutations in the CLCN1 gene encoding voltage-gated chloride channel CLC-1 and the SCN4A gene encoding voltage-gated sodium channel Nav1.4. The patients with concomitant mutations in both genes manifested different unique symptoms from mutations in these genes separately. Here, we describe a patient with myotonia and periodic paralysis in a consanguineous marriage pedigree. By using whole-exome sequencing, a novel F306S variant in the CLCN1 gene and a known R222W mutation in the SCN4A gene were identified in the pedigree. Patch clamp analysis revealed that the F306S mutant reduced the opening probability of CLC-1 and chloride conductance. Our study expanded the CLCN1 mutation database. We emphasized the value of whole-exome sequencing for differential diagnosis in atypical myotonic patients.

Abstract
Campylobacter is one of the most important foodborne pathogens worldwide, and poultry is regarded as the main reservoir of Campylobacter. The contamination of Campylobacter in broiler chickens at the farm level is closely related to the transmission of Campylobacter in the poultry production chain. This study identified 464 Campylobacter isolates from 1,534 samples from broiler rearing period and slaughtering process including 233 Campylobacter jejuni isolates and 231 Campylobacter coli isolates. We have observed a dynamic distribution of Campylobacter during broiler chicken production, that 66.3% of Campylobacter isolates were C. jejuni during broiler rearing period, while C. coli occupied 60.4% of Campylobacter isolates during the broiler slaughtering process. A tag-label method allowed us to track the dynamic of Campylobacter in each broiler chicken from 31-day age at rearing to the partition step in the slaughterhouse. At the 31-day during rearing, 150 broiler chicken were labeled, and was tracked for Campylobacter positive from rearing period to slaughtering process. Among the labeled broiler, 11 of the tracking broiler samples were able to detect Campylobacter from rearing period to slaughtering. All Campylobacter isolates from the 11 tracking samples were sequenced and analyzed. C. jejuni isolates were divided into four STs and C. coli isolates were divided into six STs. Isolates with identical core genome were observed from the same tag-labeled samples at different stages indicating a vertical transmission of Campylobacter in the early broiler meat production. Meanwhile, the core genome analysis elucidated the cross-contamination of Campylobacter during the rearing period and the slaughtering process. The virulotyping analysis revealed that all C. jejuni isolates shared the same virulotypes, while C. coli isolates were divided into three different virulotypes. The antimicrobial resistance gene analysis demonstrated that all Campylobacter isolates contained at least two antibiotic resistance genes (ARGs), and the ARG profiles were well-corresponding to each ST type. Our study observed a high prevalence of Campylobacter during the early chicken meat production, and further studies will be needed to investigate the diversity and transmission of Campylobacter in the poultry production chain.

Abstract
Mineral availability for carbon (C) binding is a key regulator of soil C storage, yet little is known about the highly reactive nanomineral assembly in the paddy soil colloids. Here, using high-resolution transmission electron microscopy (HRTEM), solid-state 27Al and 29Si nuclear magnetic resonance (NMR) spectroscopy and X-ray photoelectron spectroscopy (XPS), we investigated the coordination nature of short-range-ordered (SRO) minerals in water-dispersible colloids that were isolated from the paddy soil under different six-year fertilization regimes. Our results showed that organic fertilization not only promoted the transformation of crystalline minerals to SRO phases in the bulk soils but also increased the concentrations of Fe, Al and Si in the soil colloids compared to chemical fertilization alone, and thus enhanced the accumulation of organic C in both the bulk soils and the soil colloids. The HRTEM images revealed that water-dispersible colloids in all soils, regardless of treatment, were composed of crystalline Fe nanominerals (with some Al/Si) and SRO-Al/Si nanominerals (with some Fe) associated with organic C. Furthermore, the combined results from the 27Al and 29Si NMR spectroscopy and XPS not only confirmed the presence of SRO-Al/Si nanoparticles as Si-rich allophane and phytolith but also demonstrated that organic fertilization promoted the transformation of aluminosilicates to SRO-Al/Si nanominerals in soil colloids. Together, these findings indicate that six-year organic fertilization promotes the formation of SRO minerals (e.g., ferrihydrite, Si-rich allophane and Fe-substituted allophane, as well as phytolith) in soils and modulates the assembly of organo-mineral complexes possibly by driving the biogeochemical cycles of Fe, Al, Si and specific organic ligands, thus contributing to the long-term storage of C in paddy soils.

Abstract
Objective: To explore peptidomic changes of peptides in saliva and gingival crevicular fluid (GCF) before and after treatment of gingivitis. Methods: From January 2017 to September 2017, seventeen participants at the age of 24-62 (6 males and 11 females) at Department of Preventive Dentistry, Peking University School and Hospital of Stomatology with gingivitis were recruited in the present study. Their clinical parameters were measured and recorded. Saliva and GCF samples were collected from each of the participants at the baseline and 7 days after ultrasonic supragingival scaling, respectively. Matrix-assisted laser desorption-ionization time-of-flight mass spectrometry (MALDI-TOF MS) was employed to detect the changes of peptidomic profiles, while ano-liquid chromatography-electrospray ionization-tandem mass spectrometry (nano-LC/ESI-MS/MS) was performed to identify the possible proteins from which the peptides might derive. Results: Initially, four peptide peaks [mass-to-charge ratio (m/z) values: 1 030.6, 1 043.4, 1 053.4 and 1 064.6] were screened out exhibiting a decreasing trend after treatment (P<0.05). Besides, five peptide peaks from gingival crevicular fluid (P<0.05) exhibited differential expression, among which 1 055.5 and 1 168.3 demonstrating a decrease after treatment, while 3 363.7, 3 480.9 and 3 489.5 increased overtime. Certain positive correlations were detected between some peptides and clinical parameters. Principle component analysis using the above mentioned peptide peaks showed a distinct distribution before and after treatment and peptides from GCF showed a slightly better capacity to discriminate patients before and after treatment. The peptides with m/z values of 1 055.5 in GCF and 1 064.6 in saliva were identified to be segments of serum albumin and complement C3, respectively. Conclusions: Several differentially expressed peptides were detected in saliva and GCF by MALDI-TOF MS, exhibiting the potentiality to act as biomarkers in gingivitis patients.

Abstract
C110 oil well casing tubes should have high strength and corrosion resistance which is commonly used for deep wells operation containing corrosive media. In this paper, the microstructure evolution of a kind of semi-macro segregation originated banded structure in casing tubes is studied under different heat treatments. It is shown that the characteristics of the banded structure will change significantly in subsequent hot working and heat treatment processes. For the hot-rolled ones, the banded structure is composed of pearlite plus bainite. After quenching, it evolves into martensite band with high concentration solute elements. Finally, the banded structure will change into a carbide banding under the following tempering process. The temperature and cooling rate of the tempering practice show an obvious effect on the final band structure. To improve anti-SSC (sulfide stress corrosion cracking) performance, the favorable QT (quenching and tempering) practice for C110 steel should be a higher tempering temperature and a quicker cooling rate, from which the banded structure defects can be decreased together with an obvious improvement of the tube wall hardness uniformity.

Abstract
OBJECTIVE An increasing number of reports have shown that microRNAs (miRNAs) play a vital role in the occurrence and development of cancer by acting as tumor inhibitors or oncogenes. The purpose of this research was to explore whether the expression level of microRNA-15a-5p (miR-15a-5p) was related to TP53 regulated inhibitor of apoptosis 1 (TP53INP1) in cervical cancer, and to explore the role of miR-15a-5p in cervical cancer in vitro. PATIENTS AND METHODS Human cervical cancer tissues and adjacent normal tissues were obtained from 30 cervical cancer patients. Firstly, we carried out the quantitative Real Time-PCR (qRT-PCR) assay to evaluate the level of miR-15a-5p in cervical cancer tissues and cell lines. The TargetScan and the Dual-Luciferase Reporter Assay were used to confirm the relationship between TP53INP1 and miR-15a-5p. Besides, the Cell Counting Kit-8 (CCK-8) and the flow cytometry analysis were performed to detect the effect of miR-15a-5p on cell proliferation and apoptosis in cervical cancer cells. RESULTS Our results showed that the expression of miR-15a-5p was enhanced in cervical cancer tissues and cells lines. The data from the Dual-Luciferase Reporter Assay demonstrated that TP53INP1 was a direct target of miR-15a-5p. We also found that TP53INP1 was down-regulated in the cervical cancer tissues and cell lines compared with the adjacent normal tissues and normal cervical cells. Besides, the down-regulation of miR-15a-5p depressed cervical cancer cell proliferation and enhanced cell apoptosis. Our results clearly suggested that the down-regulation of TP53INP1 successfully impaired the tumor-inhibition effects of miR-15a-5p inhibitor in cervical cancer cells. CONCLUSIONS Our findings indicated that miR-15a-5p functioned as a tumor-promoting gene in cervical cancer by directly targeting TP53INP1, indicating that miR-15a-5p might be a potential treatment target for cervical cancer patients.

Abstract
Hepatitis B virus (HBV)/hepatitis C virus (HCV) co-infection shares the same transmission routes, and thereby it is not rare in regions where the prevalence of HBV and HCV is high. However, the co-infection rates of HBV/HCV reported in different regions of the world are relatively dissimilar, and the co-infection rates of HBV/HCV in the population are unidentified due to the presence of silent HBV infection. Thus, the phenomenon of underestimation exists. HCV may have an inhibitory effect on HBV replication when HBV/HCV is co-infected, and the effect of HBV on HCV replication remains to be certain by more studies. Furthermore, the mechanism of interaction may include the direct effect of viral proteins and the indirect effect of immune mediated host response. HBV/HCV co-infection can cause more serious chronic liver diseases and cirrhosis, and can increase the risk of liver cancer. The efficacy of peginterferon plus ribavirin in patients with HBV/HCV co-infection is same as HCV monotherapy. There are few studies on the efficacy of direct-acting antiviral drugs. Patients with HBV/HCV co-infection have the risk of HBV reactivation regardless of anti-HCV treatment with peginterferon plus ribavirin or direct-acting antiviral drugs, but the probability of HBV reactivation and how to assess and prevent it needs more studies to interpret.

Abstract
BACKGROUND Wheat-dependent exercise-induced anaphylaxis (WDEIA) is a severe allergic condition in which wheat ingestion together followed by physical exercise induces anaphylaxis. For patients with WDEIA, omega-5 gliadin is considered to be one of the major allergens. AIM To analyse the clinical features and allergen spectrum of WDEIA and to investigate the relationship between WDEIA and serum levels of platelet-activating factor (PAF), interleukin (IL)-9 and IL-33. METHODS Medical histories and conditions of WDEIA cases were collected and summarized, with allergen tests of wheat proteins measured at the same visit. Of the 33 patients enrolled, 13 also had serum levels of PAF, IL-9 and IL-33 measured. The healthy control (HC) group consisted of 13 healthy individuals, who also underwent both the wheat-protein allergen tests and the inflammatory-mediator tests. RESULTS All patients experienced severe allergic reaction during exercise after wheat ingestion. Manifestations of WDEIA included facial oedema, generalized urticaria and respiratory symptoms. Unconsciousness was also observed in 21 cases. In the patient group, 57.6% were confirmed as hypersensitive to glyceraldehyde-3-phosphate dehydrogenase (GAPDH), while 54.5% were allergic to omega-5 gliadin. PAF concentration was significantly higher in patients with WDEIA compared with HCs, whereas there was no significant difference in IL-9 or IL-33 between the two groups. CONCLUSIONS WDEIA is a rare type of anaphylaxis. GAPDH and omega-5 gliadin may be the most common allergy-causing wheat proteins for Chinese people. PAF may be associated with the onset and development of WDEIA.

Abstract
AIMS Patients with renovascular hypertension (RVH) exhibit elevated urinary mtDNA copy numbers, considered to constitute surrogate markers of renal mitochondrial injury. The modest success of percutaneous transluminal renal angioplasty (PTRA) in restoring renal function in RVH has been postulated to be partly attributable to acute reperfusion injury. We hypothesized that mitoprotection during revascularization would ameliorate PTRA-induced renal mitochondrial injury, reflected in elevated urinary mtDNA copy numbers and improve blood pressure and functional outcomes 3 months later. METHODS We prospectively measured urinary copy number of the mtDNA genes COX3 and ND1 using qPCR in RVH patients before and 24 hrs after PTRA, performed during IV infusion of vehicle (n = 8) or the mitoprotective drug elamipretide (ELAM, 0.05 mg/kg/h, n = 6). Five healthy volunteers (HV) served as controls. Urinary mtDNA levels were also assessed in RVH and normal pigs (n = 7 each), in which renal mitochondrial structure and density were studied ex-vivo. RESULTS Baseline urinary mtDNA levels were elevated in all RVH patients vs HV and directly correlated with serum creatinine levels. An increase in urinary mtDNA 24 hours after PTRA was blunted in PTRA+ELAM vs PTRA+Placebo. Furthermore, 3-months after PTRA, systolic blood pressure decreased and estimated glomerular filtration rate increased only in ELAM-treated subjects. In RVH pigs, mitochondrial damage was observed using electron microscopy in tubular cells and elevated urinary mtDNA levels correlated inversely with renal mitochondrial density. CONCLUSIONS PTRA leads to an acute rise in urinary mtDNA, reflecting renal mitochondrial injury that in turn inhibits renal recovery. Mitoprotection might minimize PTRA-associated mitochondrial injury and improve renal outcomes after revascularization.

Abstract
BACKGROUND Primary erythromelalgia (PE) is a dominant inherited disorder characterized by recurrent pain, redness, and warmth of the extremities that is caused by gain-of-function mutations in Nav1.7 encoding gene SCN9A. Most of the PE-causing mutations of Nav1.7 have been shown to be able to render Nav1.7-expressing cells hyperexcitable, however in most PE cases the symptoms are refractory to treatment with sodium channel blockers and the mechanism underlying the intractability has not been clearly clarified. OBJECTIVE To identify the mutation of SCN9A in a Chinese Han family with typical symptoms of PE and study the electrophysiological effect of the identified mutation. METHODS A Chinese Han family with typical symptoms of PE was collected and the proband's response to treatment was recorded. All the exons and flanking intronic sequences of SCN9A were amplified with PCR and sequenced. Several online programs were used to predict the damaging effect of variants. The functional effect of variants was studied by voltage-clamp analysis in CHO-K1 cells. RESULTS The PE symptoms of the proband are refractory to all kinds of reported medications. Sequence analysis of SCN9A showed that a novel c.2477T>A (p. F826Y) mutation co-segregated with the disease phenotype. Several online programs predicted that the F826Y mutation has a deleterious effect on the gene product. Voltage-clamp analysis showed that while compared with the wild-type channel, activation of the F826Y mutant channel was shifted by 7.7 mV in a hyperpolarizing direction, whereas steadystate inactivation was shifted by 4.3 mV in a depolarizing direction. CONCLUSION A novel disease-causing SCN9A Mutation (F826Y) was identified in a Chinese family with typical PE symptoms refractory to treatment. F826Y of Nav1.7 could render DRG neurons hyperexcitable, contributing to the pathogenesis of PE.

Abstract
One of the end-products of ROS-induced peroxidation, malondialdehyde (MDA), induces the cross-links in proteins, which leads to perturbation of the physiological functions of cells and contributes to abnormal biological regulation and various disorders. Taurine (2-aminoethanesulfonic acid, Tau) aids in adjusting normal physiological functions to confer stress resistance. The protective effects of Tau against MDA stress in vitro or in vivo were reported previously. In this study, we had investigated the protective effects of taurine on viability, oxidative stress levels and mitochondrial biogenesis in mouse muscle C2C12 cells undergoing MDA induced stress. We show that the treatment with 100 μM MDA leads to increase in cell oxidative stress levels, inhibition of mitochondrial biogenesis and the reduction of the cell survival rates. The pretreatment with 0.1 μM taurine reduced MDA-induced death rate via inhibition of oxidative stress, restoration of mitochondrial functions of the mitochondrial membrane potential (MMP) and ATP production. In MDA stress, the pre-treatment with 0.1 μM taurine leads to upregulation of the factors of mitochondrial biogenesis. These observations suggest that the cytoprotective effects of taurine may be due to an induction of mitochondrial biogenesis.

Abstract
Objective: To evaluate the efficacy and safety of Vesselplasty in the treatment of osteoporotic vertebral fractures and vertebral metastases. Methods: From June 2010 to December 2016, data of 81 patients with spinal diseases treated with Vesselplasty in Department of Spinal Surgery, Beijing Friendship hospital, Capital Medical University were retrospectively analyzed. There are 49 cases of vertebral fractures with age (70.2±8.2) years. Among them, 16 cases have posterior vertebral wall breakage, but no symptoms of nerve injury. Clinical result were evaluated with Visual Analogue Scale(VAS) , the kyphotic angle(Cobb's angle) and Oswestry disability index(ODI) was measured preoperatively, postoperatively and follow-up. At the same time, the operation time and cement leakage were recorded. There were 32 patients with vertebral metastases, with age of (69.6±11.1) years old. The posterior wall of the vertebral body was damaged in 22 cases. The VAS scores were recorded and compared preoperatively and postoperatively. The operation time was recorded also. Results: All patients were completed the operation safely and with no complications. Compared with preoperative VAS, postoperative VAS was significantly decreased in all subjects(P<0.05). The average operation time of each vertebral body was 16.2±4.6 min, and the postoperative VAS score significantly decreased (P<0.05), Cobb 's angle from preoperative (13.9±6.0) ° to( 5.2±4.0) ° (P<0.05) in 49 cases of vertebral fracture(58 vertebrae). The clinical results were still satisfied in follow-up . In 32 cases of vertebral metastases(38 vertebrae), the average operation time was (17.6±5.4) min. The postoperative VAS score was obviously decreased also(P<0.05). A small amount of bone cement leakage occurred in 4 cases of 4 vertebrae. The rate of bone cement leakage was 4.2%, but there were no clinical symptoms in these cases. Conclusion: Vesselplasty is a safe and effective treatment of osteoporotic vertebral fractures and vertebral metastases. It can lead to satisfactory clinical effect, partial recovery of vertebral height. Besides, the bone filling mesh can reduce the risk of bone cement leakage, which can provide a new choice for minimally invasive treatment of vertebral fracture and metastases.

Abstract
BACKGROUND Primary familial brain calcification (PFBC) is a rare calcifying disorder of the brain with extensive clinical and genetic heterogeneity. Its prevalence is underestimated due to clinical selection bias (compared with symptomatic PFBC patients, asymptomatic ones are less likely to undergo genetic testing). METHODS A total of 273 PFBC probands were enrolled in a multicenter retrospective cohort study by two different approaches. In Group I (nonsystematic approach), 37 probands diagnosed at our clinic were enrolled. In Group II (systematic approach), 236 probands were enrolled by searching the medical imaging databases of 50 other hospitals using specific keywords. Genetic testing of four genes known to be causative of autosomal dominant PFBC was performed in all probands using cDNA. All identified variants were further confirmed using genomic DNA and classified according to ACMG-AMP recommendations. RESULTS Thirty-two variants including 22 novel variants were detected in 37 probands. Among these probands, 83.8% (31/37) were asymptomatic. Two probands with homozygous pathogenic SLC20A2 variants presented more severe brain calcification and symptoms. Based on the variant detection rate of probands in Group II, we extrapolated an overall minimal prevalence of PFBC of 6.6 per 1,000, much higher than previously reported (2.1 per 1000). CONCLUSIONS We identified a higher proportion of genetically confirmed PFBC probands who were asymptomatic. These patients would be overlooked due to clinical selection bias, leading to underestimation of the disease prevalence. Considering that PFBC patients with biallelic variants had more severe phenotypes, this specific condition should be focused on in genetic counseling.
