Abstract
The frequency of Cryptosporidium infection in yaks from Qinghai province, People's Republic of China, was determined from examination of 1,027 fecal samples collected from 979 adult yaks and 48 yak calves during 4 seasons from 7 geographic areas within the province. PCR amplification of extracted DNA was used to characterize the different species of Cryptosporidium oocysts isolated by fecal examination. Twenty-six (2.53%) positive samples were identified and successfully sequenced: 17 Cryptosporidium ryanae (65.38%), 8 Cryptosporidium bovis (30.77%), and 1 Cryptosporidium baileyi (3.85%). The results of the study indicate that autumn is the primary season for transmission of Cryptosporidium to susceptible yak calves given the favorable temperatures and higher altitude of Qinghai province. To our knowledge, C. baileyi, a species predominately associated with birds (avian hosts), is described for the first time in yaks.

Abstract
Using an age-structured process-based simulation model for diamondback moth (DBM), we model the population dynamics of this major Brassica pest using the cropping practices and climate of Guangdong, China. The model simulates two interacting sub-populations (demes), each representing a short season crop. The simulated DBM abundance, and hence pest problems, depend on planting regime, crop hygiene and biological control. A continuous supply of hosts, a low proportion of crop harvested and long residue times between harvest and replanting each exacerbate pest levels. Biological control provided by a larval parasitoid can reduce pest problems, but not eliminate them when climate is suitable for DBM and under certain planting practices. The classic Integrated Pest Management (IPM) method of insecticide application, when pest threshold is reached, proved effective and halved the number of insecticide sprays when compared with the typical practice of weekly insecticide application.

Abstract
We present first results on the scalar coupling of weakly interacting massive particles (WIMPs) to pions from 1 t yr of exposure with the XENON1T experiment. This interaction is generated when the WIMP couples to a virtual pion exchanged between the nucleons in a nucleus. In contrast to most nonrelativistic operators, these pion-exchange currents can be coherently enhanced by the total number of nucleons and therefore may dominate in scenarios where spin-independent WIMP-nucleon interactions are suppressed. Moreover, for natural values of the couplings, they dominate over the spin-dependent channel due to their coherence in the nucleus. Using the signal model of this new WIMP-pion channel, no significant excess is found, leading to an upper limit cross section of 6.4×10^{-46} cm^{2} (90% confidence level) at 30 GeV/c^{2} WIMP mass.

Abstract
A search for the rare decay K_{L}→π^{0}νν[over ¯] was performed. With the data collected in 2015, corresponding to 2.2×10^{19} protons on target, a single event sensitivity of (1.30±0.01_{stat}±0.14_{syst})×10^{-9} was achieved and no candidate events were observed. We set an upper limit of 3.0×10^{-9} for the branching fraction of K_{L}→π^{0}νν[over ¯] at the 90% confidence level (C.L.), which improved the previous limit by almost an order of magnitude. An upper limit for K_{L}→π^{0}X^{0} was also set as 2.4×10^{-9} at the 90% C.L., where X^{0} is an invisible boson with a mass of 135 MeV/c^{2}.

Abstract
Hypoxia-inducible factor-1α (HIF-1α) is a key transcription factor to initiate the expressions of distinct pro-angiogenic growth genes, particularly the expression of vascular endothelial growth factor (VEGF).CoCl2 was used in rat liver tumor cell line McA RH-7777 to stimulate hypoxia to mimic the hypoxic conditions induced by transcatheter arterial chemoembolization (TACE). CCK8 assays were performed to examine the effect of hypoxia on cell viability. Real-time qRT-PCR, western blot and ELISA assays were used to measure the expression of HIF-1α and VEGF in McA RH-7777 cells under hypoxic conditions, respectively. Lentivirus-mediated HIF-1α and/or VEGF-specific shRNA was used to establish single or HIF-1α and VEGF double knocking-down McA RH-7777 cells. Transwell assays were performed to examine the effect of HIF-1α and VEGF knocking-down on McA RH-7777 cells migration and invasion.The mRNA and protein expression level of HIF-1α and VEGF were remarkably up-regulated in McA RH-7777 cells under hypoxic conditions, respectively. The knockdown of HIF-1α or VEGF significantly reduced the expression of the secreted VEGF. More importantly, knockdown of both HIF-1α and VEGF resulted in the best effective inhibitory effect in VEGF expression, and in turn remarkably reduced the cell migration and invasion activity.Our findings showed that HIF-1α play an important role in the stimulation of the secreted VEGF expression under hypoxic conditions, suggesting that targeting both HIF-1α and VEGF could represent a potential therapeutic strategy in combination with TACE in the treatment of liver tumors.

Abstract
Objective: Percutaneous radiofrequency thermocoagulation (RFT) of the Gasserian ganglion is an effective treatment for refractory trigeminal craniofacial pain.In the present study, we assessed the feasibility of accessing the Gasserian ganglion through the foramen ovale with neuronavigation guidance in the patients of trigeminal craniofacial pain. Method: We retrospectively analyzed forty-four patients with type Ⅰ trigeminal neuralgia who had undergone percutaneous RFT treatment in our hospital from June 2014 to December 2016.The patients were divided into fluoroscopy group and navigation group according to the intraoperative guiding manners for foramen ovale cannulation.We compared groups in terms of the duration of the whole RFT procedure and times of intraoperative fluoroscopy.We also analyzed the immediate and late outcome accessing by Barrow Neurological Institute (BNI) pain scale, as well as the complication rates in groups. Result: There were 32 patients in the fluoroscopy group and 12 in the navigation group.The duration of the surgical procedure in navigation group was less than that in fluoroscopy group (46±12 min versus 67±16 min, P=0.00), and times of intraoperative fluoroscopy was reduced (6.3±2.2 versus 1.3±1.6, P=0.00). The learning curve of navigation-aid RFT was not steep in the present study overall.There was no significant difference between groups regarding pain reduction at the immediate (P=0.07) or late follow-up (P=0.400) time points.However, the rate of pain reduction to BNI-Ⅰ grade was greater in navigation group (P=0.026). No significant difference in the complication rate between both groups, and no serious complications were observed in the both groups. Conclusion: Neuronavigation may be encouraged in trigeminal Gasserian ganglion RFT with better operating efficiency and less radiation exposure.The immediate and late therapeutic effects for craniofacial pain control were positive, whereas further studies are necessary.

Abstract
Objective: To explore the role of MRI in the pre-operative diagnosis and classification of oblique vaginal septum syndrome (OVSS) . Methods: A retrospective analysis of the clinical records and pre-operative MRI images of 19 patients with surgery proved OVSS was carried out. Two experienced radiologists reviewed the pre-operative pelvic MRI of the 19 patients in consensus blind to the surgery results. Characteristics including malformations of the uterus, cervix and vagina, the diagnosis of the disorder and classification were evaluated. Pre-operative MRI diagnosis and classification were correlated with surgical findings. Results: Mean age of onset of symptoms for the 19 patients was 15 years (ranged 9-25 years) , and mean age of menarche was 12 years. Ten patients suffered from dysmenorrhea or lower abdominal pain, 5 patients complained of vaginal discharge, 3 patients had a history of irregular menstruation, 1 patient suffered from primary infertility. All 19 patients showed uteri didelphys. Eighteen patients showed vaginal oblique septum.One patient showed cervical atresia.MRI was completely correlated with the surgery in the pre-operative diagnosis of OVSS. MRI classification was in line with surgery in 17 patients, including 9 patients with imperforate septum (typeⅠ) , 6 patients with perforate septum (type Ⅱ) , 1 patient with imperforate septum and cervical fistula (type Ⅲ) , and another one with cervical agenesis (type Ⅳ) . One case of type Ⅱ was misdiagnosed as type Ⅰ, another one of type Ⅰ was misdiagnosed as type Ⅲ. Pre-operative MRI classification was correlated with surgery in 17 out of 19 patients. Conclusion: Pre-operative MRI allows excellent manifestation and accurate diagnosis of OVSS, and could also facilitate the evaluation of the classification.

Abstract
We report on a search for weakly interacting massive particles (WIMPs) using 278.8 days of data collected with the XENON1T experiment at LNGS. XENON1T utilizes a liquid xenon time projection chamber with a fiducial mass of (1.30±0.01) ton, resulting in a 1.0 ton yr exposure. The energy region of interest, [1.4,10.6] keV_{ee} ([4.9,40.9] keV_{nr}), exhibits an ultralow electron recoil background rate of [82_{-3}^{+5}(syst)±3(stat)] events/(ton yr keV_{ee}). No significant excess over background is found, and a profile likelihood analysis parametrized in spatial and energy dimensions excludes new parameter space for the WIMP-nucleon spin-independent elastic scatter cross section for WIMP masses above 6 GeV/c^{2}, with a minimum of 4.1×10^{-47} cm^{2} at 30 GeV/c^{2} and a 90% confidence level.

Abstract
Recently, 2-methoxyestradiol (2-ME) has been considered to be a potential anticancer agent but has not been investigated in bladder cancer. This study was conducted to clarify the role of 2-ME in bladder cancer cells. The bladder cancer cell line T-24 was treated with 2 μm 2-ME for 2 d. The T-24 cell viability, colony formation, invasion and apoptosis were observed in 2-ME-treated and control cells. The expression of hypoxia-inducible factor 1 alpha (HIF-1α) was detected using reverse transcription-polymerase chain reaction (RT-PCR). Then western blotting assay was applied to assess expressions of HIF-1α and apoptosis factors caspase-3 and Bcl-x proteins. The mRNA and protein expressions of HIF-1α in 2-ME-treated T-24 cells were remarkably lower than that of the control cells (P < 0.05). Treatment of 2-ME could significantly inhibit T-24 the cell viability, colony formation, invasion, and promote apoptosis (all P < 0.05). In addition, the protein expression of Caspase-3 was higher and that of Bcl-x protein was lower after administration of 2-ME compared to control (both P < 0.05). Collectively, we characterized the efficacy of 2-ME on bladder cancer T-24 cells as being mediated by inhibition of cell viability, colony fomation, invasion and promoting cell apoptosis, which may be achieved by suppressing HIF-1α levels. This study suggests 2-ME as a potential drug for bladder cancer therapy.

Abstract
Objective: To investigate the changes in psychological state after occupational exposure in the AIDS occupational exposure population and related influencing factors, and to provide baseline data and a basis for related departments to conduct mental health prevention and intervention for personnel with occupational AIDS exposure. Methods: AIDS risk assessment was performed for all personnel with occupational AIDS exposure in 2014 in Nanning, China, and the Symptom Checklist-90 (SCL-90) psychological scale was used for psychological state evaluation at 24 hours, 1 week, and 3 months after occupational exposure in all persons who met the research criteria. Results: Most of the persons with occupational AIDS exposure came from secondary and tertiary hospitals (85%) , and nurses accounted for the highest percentage (78.3% ). The age ranged from 21 to 50 years, and the mean age was 31.02 ± 7.92 years. The persons with occupational AIDS exposure aged 20~29 years accounted for the highest percentage (51.6%) , and most persons (76.7%) graduated from junior colleges. Compared with the adult norm, there was significant increases in the total psychological score and the number of positive items after occupational exposure (P<0.05). The scores of all items at 24 hours were significantly higher than those at the other time points, and the scores of all items gradually decreased over time (F=227.24, 267.57, and 287.46, P<0.05). Compared with the adult norm, there were significant increases in the factor points at 24 hours and significant reductions in the factor points at 3 months (P<0.05). Compared with those at 24 hours, the factor scores at 3 months decreased significantly (P<0.05). Conclusion: Occupational AIDS exposure affects the mental status of related personnel, and the mental status at 24 hours after exposure is poor. Related departments should provide corresponding psychological counseling for the occupational exposure population at different exposure times.

Abstract
Objective Condyloma acuminatum (CA) is a common, viral, sexually transmitted disease worldwide. Human papillomavirus (HPV) genotyping has important clinical implications for the treatment of CA. We developed a loop-mediated isothermal amplification (LAMP) method for the detection of HPV. Methods We collected 294 cervical scrape samples, including 30 HPV-6-positive, 30 HPV-11-positive, 22 HPV-16-positive, 20 HPV-42-positve, 30 HPV-43-positive, 20 HPV-44-positive and 142 HPV-negative samples. Tissues from 40 patients with a pathological diagnosis of CA were paraffin-embedded and analyzed by LAMP and Luminex. Hydroxynaphthol blue (HNB) and electrophoresis were used to detect the results of LAMP. Results LAMP and Luminex systems were compared in detecting six subtypes of HPV. LAMP reactions were specific for each subtype. The sensitivity of LAMP for HPV-6, as determined by the HNB indicator assay, was 1000 copies/tube. The kappa value between the two methods was 0.98 (HPV-6), 0.94 (HPV-11), 0.89 (HPV-43), 0.87 (HPV-42) 0.79 (HPV-16) and 0.68 (HPV-44). Among the 142 HPV-negative samples determined by the Luminex assay, HPV-6 was detected in eight and HPV-11 in one by LAMP. Among the 40 CA samples, the results of LAMP and Luminex were in agreement in 38 (95%). Conclusion The results of this study indicated that the LAMP assay with HNB is superior to the Luminex method in terms of sensitivity and specificity. The specificity of LAMP was 100% and the sensitivity of LAMP was 1000 copies/tube using HNB. LAMP is therefore a useful, quick and accurate method for the clinical diagnosis of HPV subtypes.
