RESUMEN
Virtual bronchoscopic navigation (VBN) is increasingly being used to diagnose peripheral lung lesions, allowing precise guidance of the bronchoscope to the target lesions, thereby improving diagnostic accuracy. This paper reported a patient admitted due to hemoptysis, with an initial clinical diagnosis of squamous cell lung carcinoma with brain and bone metastases. Previous attempts had failed to obtain tissue samples from the lung lesions. Upon admission, the LungPro navigation system was used to perform a bronchoscopic transparenchymal nodule access (BTPNA). Pathological examination of the lung tissue and microbiological analysis of bronchoalveolar lavage fluid confirmed the diagnosis of peripheral cavitary squamous cell lung carcinoma with Aspergillus infection. Following antifungal and antineoplastic treatment, the patient's symptoms improved markedly and she was subsequently discharged.

Nocardia is a rarely encountered opportunistic gram-positive bacterium that exhibits marked invasiveness and dissemination. Typically, acquired through trauma or inhalation, this pathogen primarily affects immunocompromised individuals and is a potentially life-threatening risk in severe cases. Nocardia otitidiscaviarum is a particularly rare subtype of Nocardia infection, and the occurrence of concurrent Aspergillus infection is extremely rare. In cases where both infections manifest concomitantly, rapid and accurate diagnosis is essential to facilitate the subsequent selection of appropriate anti-infective interventions. This paper reported the diagnostic and therapeutic experience in managing a case of pulmonary co-infection with Nocardia otitidiscaviarum and Aspergillus. The patient presented with an acute onset, rapid progression, and early manifestation of respiratory failure. The diagnostic process included respiratory pathogen culture and bronchoscopy, which was supplemented with targeted next-generation sequencing (tNGS). These comprehensive diagnostic modalities led to the identification of pulmonary co-infection with Nocardia otitidiscaviarum and Aspergillus. After adjustment of the antibiotic regimen, the patient's condition improved rapidly, culminating in a timely discharge.

OBJECTIVES: This study systematically reviewed scientific evidence regarding the impact of economic growth on physical activity (PA) and sedentary behaviors. METHODS: A keyword and reference search was conducted in PubMed, Web of Science, Cochrane Library, Scopus, and EBSCO from the inception of an electronic bibliographic database to November 2021. Studies that met all of the following criteria were included in the review: (1) study designs: observational studies; (2) study subjects: people of all ages; (3) exposure: macroeconomic growth; (4) outcomes: PA or sedentary behaviors/sitting time. RESULTS: 15 studies were identified. Eight among 12 studies found economic growth positively associated with at least one domain/measure of PA, whereas the remaining four found an inverse relationship. One of two studies examined the association of economic growth and physical inactivity found a positive relationship, while another found no significant relationship. Four studies examined the associations between economic growth and sedentary behaviors, and the results were inconclusive. The impact of economic growth on PA is through three main pathways-(a) building and maintaining parks and green spaces, (b) adoption of the modern workplace and high technology, and (c) motorized transportation. CONCLUSION: Building and maintaining parks and green spaces can effectively promote leisure time physical activity and active commute in developed countries, whereas promoting workplace and transportation-related PA could be prioritized in developing nations. Future research calls for longitudinal study design and further exploration of macro-environmental factors. Policymakers and stakeholders should be informed about the potential PA reduction resulting from economic growth and develop preventive strategies to alleviate the problem.

Objective: To investigate the histopathological and immunohistochemical characteristics of benign apocrine cystic papillary hyperplasia of the breast with loss of myoepithelial cell layer. Methods: The clinical data, histopathological features and immunohistochemical profile of patients with benign apocrine cystic papillary hyperplasia of breast with loss of myoepithelial cell layer from January 2016 to December 2021 were examined, in which six patients were identified. Results: All six patients were female, aged 36-61 years (median 46 years), who presented with a breast mass; three cases were from the left breast and three cases were from the right breast. Microscopic examination of all cases showed breast hyperplasia with apocrine cysts, accompanied by different degrees of micropapillary and papillary hyperplasia of apocrine cells. One case was associated with lobular carcinoma in situ, and one case was associated with apocrine ductal carcinoma in situ with intraductal dissemination in adenosis. Immunohistochemical staining of CK5/6, p63, SMA, SMMHC, Calponin and CD10 showed complete absence of myoepithelial cell layer surrounding ducts in apocrine cystic papillary hyperplasia. Conclusions: The myoepithelial cells of apocrine cystic papillary hyperplasia of the breast may undergo abnormal changes and may even be completely lost. The diagnosis should be comprehensively considered along with cytomorphological and histological features to avoid overdiagnosis.

We present an all-sky 90% confidence level upper limit on the cosmic flux of relativistic magnetic monopoles using 2886 days of IceCube data. The analysis was optimized for monopole speeds between 0.750c and 0.995c, without any explicit restriction on the monopole mass. We constrain the flux of relativistic cosmic magnetic monopoles to a level below 2.0×10^{-19} cm^{-2} s^{-1} sr^{-1} over the majority of the targeted speed range. This result constitutes the most strict upper limit to date for magnetic monopoles with ßâ³0.8 and up to ßâ¼0.995 and fills the gap between existing limits on the cosmic flux of nonrelativistic and ultrarelativistic magnetic monopoles.
RESUMEN
We present a measurement of ν_{e} interactions from the Fermilab Booster Neutrino Beam using the MicroBooNE liquid argon time projection chamber to address the nature of the excess of low energy interactions observed by the MiniBooNE Collaboration. Three independent ν_{e} searches are performed across multiple single electron final states, including an exclusive search for two-body scattering events with a single proton, a semi-inclusive search for pionless events, and a fully inclusive search for events containing all hadronic final states. With differing signal topologies, statistics, backgrounds, reconstruction algorithms, and analysis approaches, the results are found to be either consistent with or modestly lower than the nominal ν_{e} rate expectations from the Booster Neutrino Beam and no excess of ν_{e} events is observed.
RESUMEN
We report results from a search for neutrino-induced neutral current (NC) resonant Δ(1232) baryon production followed by Δ radiative decay, with a ⟨0.8⟩ GeV neutrino beam. Data corresponding to MicroBooNE's first three years of operations (6.80×10^{20} protons on target) are used to select single-photon events with one or zero protons and without charged leptons in the final state (1γ1p and 1γ0p, respectively). The background is constrained via an in situ high-purity measurement of NC π^{0} events, made possible via dedicated 2γ1p and 2γ0p selections. A total of 16 and 153 events are observed for the 1γ1p and 1γ0p selections, respectively, compared to a constrained background prediction of 20.5±3.65(syst) and 145.1±13.8(syst) events. The data lead to a bound on an anomalous enhancement of the normalization of NC Δ radiative decay of less than 2.3 times the predicted nominal rate for this process at the 90% confidence level (C.L.). The measurement disfavors a candidate photon interpretation of the MiniBooNE low-energy excess as a factor of 3.18 times the nominal NC Δ radiative decay rate at the 94.8% C.L., in favor of the nominal prediction, and represents a greater than 50-fold improvement over the world's best limit on single-photon production in NC interactions in the sub-GeV neutrino energy range.
RESUMEN
We report a measurement of the energy-dependent total charged-current cross section σ(E_{ν}) for inclusive muon neutrinos scattering on argon, as well as measurements of flux-averaged differential cross sections as a function of muon energy and hadronic energy transfer (ν). Data corresponding to 5.3×10^{19} protons on target of exposure were collected using the MicroBooNE liquid argon time projection chamber located in the Fermilab booster neutrino beam with a mean neutrino energy of approximately 0.8 GeV. The mapping between the true neutrino energy E_{ν} and reconstructed neutrino energy E_{ν}^{rec} and between the energy transfer ν and reconstructed hadronic energy E_{had}^{rec} are validated by comparing the data and Monte Carlo (MC) predictions. In particular, the modeling of the missing hadronic energy and its associated uncertainties are verified by a new method that compares the E_{had}^{rec} distributions between data and a MC prediction after constraining the reconstructed muon kinematic distributions, energy, and polar angle to those of data. The success of this validation gives confidence that the missing energy in the MicroBooNE detector is well modeled and underpins first-time measurements of both the total cross section σ(E_{ν}) and the differential cross section dσ/dν on argon.
RESUMEN
AIM: To investigate the diagnostic performance of the radiomics features of pericoronary adipose tissue (PCAT) in determining haemodynamically significant coronary artery stenosis as evaluated by fractional flow reserve (FFR). MATERIALS AND METHODS: A total of 92 patients with clinically suspected coronary artery disease who underwent coronary computed tomography (CT) angiography (CCTA), invasive coronary angiography (ICA), and FFR examination within 1 month were included retrospectively, and 121 lesions were randomly assigned to the training and testing set. Based on manual segmentation of PCAT, 1,116 radiomics features were computed. After radiomics robustness assessment and feature selection, radiomics models were established using the different machine-learning algorithms. The area under the receiver operating characteristic (ROC) curve (AUC) and net reclassification index (NRI) were analysed to compare the discrimination and reclassification abilities of radiomics models. RESULTS: Two radiomics features were selected after exclusions, and both were significantly higher in coronary arteries with FFR ≤0.8 than those with FFR >0.8. ROC analysis showed that the combination of CCTA and decision tree radiomics model achieved significantly higher diagnostic performance (AUC: 0.812) than CCTA alone (AUC: 0.599, p=0.015). Furthermore, the NRI of the combined model was 0.820 and 0.775 in the training and testing sets, respectively, suggesting the radiomics features of PCAT had were effective in classifying the haemodynamic significance of coronary stenosis. CONCLUSIONS: Adding PCAT radiomics features to CCTA enabled identification of haemodynamically significant coronary artery stenosis.

OBJECTIVE: This study aimed to evaluate the effectiveness and safety of traditional Chinese medicine (TCM) for postmenopausal osteoporosis (PMOP). METHODS: We conducted a computer literature search in five databases and comprehensively extracted all kinds of information from each article. Traditional Chinese medicine inheritance support system (TCMISS) V2.5 was adopted to perform association analysis. The effectiveness, safety and methodological quality were analyzed using randomized controlled clinical trials (RCTs). RESULTS: A total of 2880 related articles were collected. Finally, 423 articles which included 312 RCTs were included for in-depth analysis. We collected 369 Chinese medicine prescriptions and found that the top three frequently used herbs in the treatment of PMOP were Epimedii Folium (Yinyanghuo), Rehmanniae Radix Praeparata (Shudihuang) and Angelicae Sinensis Radix (Danggui). The top Chinese patent medicine was Gushukang capsule. No serious adverse reaction (AR) had been reported in the Chinese medical treatment group. CONCLUSION: The effectiveness of TCM in treating PMOP needs to be further explored, and the safety is good. Therefore, high-quality evidence is urgently needed to supplement.

BACKGROUND: Vulvovaginal candidiasis (VVC) is frequent in women of reproductive age, but very limited data are available on the epidemiology in cases of VVC in China. OBJECTIVES: The current study has been conducted to reveal the prevalence, species distribution of yeast causing VVC and molecular genetics of Candida albicans in China. METHODS: Vaginal swabs were collected from 543 VVC outpatients recruited in 12 hospitals in China between September 2017 and March 2018. They were preliminarily incubated on Sabouraud dextrose agar and then positive subjects of which were then transmitted to our institute for further identification. CHROMagar™ was used to isolate Candida species, and all isolates were finally identified by DNA sequencing. Multilocus sequence typing (MLST) was used to analyse phylogenetic relationships of the various C. albicans isolates. RESULTS: Eleven different yeast species were identified in 543 isolates, among which C. albicans (84.7%) was the most frequent, followed by C. glabrata (8.7%). We obtained 117 unique diploid sequence types from 451 clinical C. albicans isolates and 92 isolates (20.4%) belonged to a New Clade. All the strains appearing in the New Clade were from northern China and they were isolated from non-recurrent VVC. CONCLUSIONS: Our findings suggest that C. albicans are still the main cause of VVC in China and the majority of C. albicans isolates belongs to Clade 1 with DST 79 and DST 45 being two most common. Moreover, the New Clade revealed in our study seems to be specific to northern China.

BACKGROUND: This study evaluated maintenance treatment with niraparib, a potent inhibitor of poly(ADP-ribose) polymerase 1/2, in patients with platinum-sensitive recurrent ovarian cancer. PATIENTS AND METHODS: In this phase III, double-blind, placebo-controlled study conducted at 30 centers in China, adults with platinum-sensitive recurrent ovarian cancer who had responded to their most recent platinum-containing chemotherapy were randomized 2 : 1 to receive oral niraparib (300 mg/day) or matched placebo until disease progression or unacceptable toxicity (NCT03705156). Following a protocol amendment, patients with a bodyweight <77 kg or a platelet count <150 × 103/µl received 200 mg/day, and all other patients 300 mg/day, as an individualized starting dose (ISD). Randomization was carried out by an interactive web response system and stratified by BRCA mutation, time to recurrence following penultimate chemotherapy, and response to most recent chemotherapy. The primary endpoint was progression-free survival (PFS) assessed by blinded independent central review. RESULTS: Between 26 September 2017 and 2 February 2019, 265 patients were randomized to receive niraparib (n = 177) or placebo (n = 88); 249 patients received an ISD (300 mg, n = 14; 200 mg, n = 235) as per protocol. In the intention-to-treat population, median PFS was significantly longer for patients receiving niraparib versus placebo: 18.3 [95% confidence interval (CI), 10.9-not evaluable] versus 5.4 (95% CI, 3.7-5.7) months [hazard ratio (HR) = 0.32; 95% CI, 0.23-0.45; P < 0.0001], and a similar PFS benefit was observed in patients receiving an ISD, regardless of BRCA mutation status. Grade ≥3 treatment-emergent adverse events occurred in 50.8% and 19.3% of patients who received niraparib and placebo, respectively; the most common events were neutrophil count decreased (20.3% versus 8.0%) and anemia (14.7% versus 2.3%). CONCLUSIONS: Niraparib maintenance treatment reduced the risk of disease progression or death by 68% and prolonged PFS compared to placebo in patients with platinum-sensitive recurrent ovarian cancer. Individualized niraparib dosing is effective and safe and should be considered standard practice in this setting.

We present a search for the decays of a neutral scalar boson produced by kaons decaying at rest, in the context of the Higgs portal model, using the MicroBooNE detector. We analyze data triggered in time with the Fermilab NuMI neutrino beam spill, with an exposure of 1.93×10^{20} protons on target. We look for monoenergetic scalars that come from the direction of the NuMI hadron absorber, at a distance of 100 m from the detector, and decay to electron-positron pairs. We observe one candidate event, with a standard model background prediction of 1.9±0.8. We set an upper limit on the scalar-Higgs mixing angle of θ<(3.3-4.6)×10^{-4} at the 95% confidence level for scalar boson masses in the range (100-200) MeV/c^{2}. We exclude, at the 95% confidence level, the remaining model parameters required to explain the central value of a possible excess of K_{L}^{0}âπ^{0}νν[over ¯] decays reported by the KOTO collaboration. We also provide a model-independent limit on a new boson X produced in KâπX decays and decaying to e^{+}e^{-}.
RESUMEN
OBJECTIVES: This study systematically reviewed evidence from interventions on the effect of front-of-package (FOP) nutrition labeling on food purchases. STUDY DESIGN: The study design used in this study is a systematic review. METHODS: Keyword search was performed in PubMed, Web of Science, Scopus, and Cochrane Library. RESULTS: Fifteen studies (10 randomized controlled trials, four pre-post studies, and one case-control study) met the eligibility criteria and were included in the review. Five studies were conducted in a controlled setting through the establishment of an online virtual supermarket or physical laboratory food store solely for the intervention. In contrast, the remaining ten studies were conducted in a naturalistic setting where people commonly purchase foods (e.g., supermarket, grocery store, school/hospital cafeteria, or vending machine). FOP labels assessed included traffic lights, health star rating, daily intake guides, health warnings, and high sugar symbol labels. Compared with the control, FOP labels were effective for helping participants make healthier food purchase decisions in five of the 12 studies that assessed traffic lights labels, in one of the two studies that assessed health warning labels, and in one study that assessed high sugar symbol labels. Three assessed health star ratings and one assessed daily intake guide labels, but none revealed an effect on food purchases compared with the control. CONCLUSIONS: Findings on the effectiveness of FOP nutrition labels in 'nudging' consumers toward healthier food purchases remain mixed and inconclusive. Future studies should examine other types of FOP labels beside the traffic lights labels and explore the different effects by consumer affordability, population subgroup, and shopping environment.

To investigate the diversity and composition of gut microbiota in patients with lung adenocarcinoma and lung squamous cell carcinoma. A single-center and case-control study was conducted to consecutively enroll a total of 27 lung cancer patients, including 15 males and 12 females, who were seen at the Affiliated Hangzhou First People's Hospital, Zhejiang University School of Medicine between September 2018 to October 2020. A total of 20 cases of healthy healthy physical examiners, including 9 males and 11 females were recruited as healthy control group (HC) during the same period. Clinical data and stool samples were collected from each participants, and lung cancer patients were divided into lung adenocarcinoma group (AC, 19 patients, 8 males and 11 females) and lung squamous cell carcinoma group (SCC, 8 patients, 7 males and 1 females) according to the pathology type. Genomic DNA were extracted to amplify 16S rDNA V3-V4 region, then the Illumina MiSeq high-throughput sequencing platform and QIIME software were used for sequencing and analyzing the structure of the gut microbiota, respectively. Analysis of variance, χ2 test, K-W test were used to analyze the differences in age, gender,α diversity, and relative abundance of microbiota among the three groups. AC, SCC, and HC were aged (58.74±9.27), (63.38±6.12), and (55.65±7.79) years old, respectively. There were no difference in gender and age among the three groups (gender and age are respectively:χ2=5.155, P=0.076;F=2.598,P=0.086). And no significant difference in alpha diversity were found among the three groups (Chao and Shannon index were respectively: F=0.616, P=0.545; F=2.484, P=0.095), while ß-diversity analysis indicated significant differences in the structure of intestinal flora among AC, SCC and HC (P=0.001). LEfSe analysis showed that AC and SCC both have dominant bacterials. Megasphaera (H=7.855,P=0.020) and Erysipelatoclostridium (H=7.426,P=0.024) were enriched in patients with AC, while Enterococcus (H=8.400, P=0.015), Veillonella (H=9.957,P=0.007), and Eubacterium_eligens_group (H=10.514,P=0.005) were enriched in patients with SCC. Lung cancer patients have gut microbiota imbalance, while lung adenocarcinoma and lung squamous cell carcinoma patients have no significant difference in gut microbiota diversity, but lung adenocarcinoma and lung squamous cell carcinoma have their own unique microbiota. This imbalance of the intestinal microenvironment is of great significance for studying the occurrence and development of different pathological types of lung cancer.

Objective: To examine the clinical characteristics and abnormal reflux branches of primary isolated chylopericardium. Methods: Totally 43 patients with primary isolated chylopericardium at Department of Lymphatic Surgery, Affiliated Beijing Shijitan Hospital,Capital Medical University from June 2007 to January 2018 were recruited in this study. There were 21 males and 22 females, aging (23.0±15.9) years (range: 2 to 57 years). The levels of triglyceride, total cholesterol, total protein and albumin in pericardial effusion and blood were compared by paired-t test, and the characteristics of lymphatic system in direct lymphangiography and postoperative CT were analyzed. Results: Pericardial effusion was mainly milky white and monocytes, and 95.3%(41/43) were positive for Rivalta test. The level of triglyceride in pericardial effusion was significantly higher than that of blood ((9.67±5.11) mmol/L vs. (1.28±0.89) mmol/L, t=10.557, P<0.01), and the levels of total cholesterol ((2.19±0.52) mmol/L vs. (4.12±1.06) mmol/L, t=-3.732, P<0.01), total protein ((61.25±16.17) g/L vs. (68.26±8.30) g/L, t=-2.958, P=0.005) and albumin ((36.63±7.06) g/L vs. (42.32±4.73) g/L, t=-5.747, P<0.01) were significantly lower than that of blood. In the direct lymphangiography, the imaging of iliac and retroperitoneal lymphatics showed dilated or tortuous in 90.7% (39/43), the thoracoabdominal segment of thoracic duct showed dilation in 46.5% (20/43), and cervical thoracic duct imaging showed dilation in 44.2% (19/43) and stenosis in 55.8% (24/43). The image of lipiodol flowing into the vein showed obstruction at the venous angle. There were 60.5%(26/43) of the patients with lipiodol reflux through the bronchomediastinal trunk (type â ), 11.6%(5/43) with lipiodol diffusion to the pericardium through the abnormal pathway from the thoracic segment of the thoracic duct (type â ¡), while no communication pathway between the thoracic duct and the pericardial cavity (type â ¢) found in 27.9%(12/43). CT images obtained after the direct lymphangiography showed 34.9%(15/43) had abnormal distribution of lipiodol in pericardium, mediastinal lymph nodes and lung hilar lymph nodes, 46.5%(20/43) in mediastinal lymph nodes and lung hilar lymph nodes, 14.0%(6/43) only mediastinal lymph nodes, 4.6%(2/43) had no lipiodol in the above areas. Conclusions: Pericardial effusion compared with same period blood, has higher triglyceride, lower total cholesterol, total protein and albumin. The obstruction of the cervical segment of the thoracic duct and the formation of abnormal reflux branches would be corelative to primary isolated chylopericardium.

We report on the first measurement of flux-integrated single differential cross sections for charged-current (CC) muon neutrino (ν_{µ}) scattering on argon with a muon and a proton in the final state, ^{40}Ar (ν_{µ},µp)X. The measurement was carried out using the Booster Neutrino Beam at Fermi National Accelerator Laboratory and the MicroBooNE liquid argon time projection chamber detector with an exposure of 4.59×10^{19} protons on target. Events are selected to enhance the contribution of CC quasielastic (CCQE) interactions. The data are reported in terms of a total cross section as well as single differential cross sections in final state muon and proton kinematics. We measure the integrated per-nucleus CCQE-like cross section (i.e., for interactions leading to a muon, one proton, and no pions above detection threshold) of (4.93±0.76_{stat}±1.29_{sys})×10^{-38} cm^{2}, in good agreement with theoretical calculations. The single differential cross sections are also in overall good agreement with theoretical predictions, except at very forward muon scattering angles that correspond to low-momentum-transfer events.
RESUMEN
AIM: This study was carried out to investigate the effects of dietary calcium pyruvate supplementation on growth performance and intestinal health of weaned piglets fed low-protein diets. METHODS AND RESULTS: After a 7-day adaptation period, 60 individually housed piglets (Duroc × Yorkshire-Landrace) weaned at 28 days of age were randomly assigned to receive one of three treatments (20 pigs/treatment) for 28 days: control diet (20·0% crude protein [CP]), low-protein diet (15·5% CP), and experimental (15·5% CP + 1·8% calcium pyruvate). At the end of the experiment, six piglets from each diet group were slaughtered and blood and tissue samples were collected. Compared with the control group, feeding piglets with 15·5% CP decreased the daily body weight gain; lengths of the duodenum, jejunum and ileum; and weights of the stomach, duodenum, jejunum and ileum (P < 0·05), while 15·5% CP + 1·8% calcium pyruvate supplementation removed those differences (P > 0·05). Compared with the control group, the diarrhoea incidence and relative richness of Firmicutes in the colon contents of piglets in both the 15·5% CP and 15·5% CP + 1·8% calcium pyruvate groups was decreased. The relative richness of Bacteriodetes in the colon contents of piglets was higher in the 15·5% CP + 1·8% calcium pyruvate group than in the control and 15·5% CP groups (P < 0·05). CONCLUSION: Calcium pyruvate supplementation for four weeks removed the negative effects of a low-protein diet on the gastrointestinal tract development and daily body weight gain of weaned piglets. SIGNIFICANCE AND IMPACT OF THE STUDY: This study showed that supplementing a low-protein diet with calcium pyruvate, an effective alternative metabolic fuel to amino acids, was beneficial in improving the intestinal health and maximizing the growth of newly weaned piglets.

Objective: Using clotrimazole vaginal tablet as a positive control, to evaluate the results of clotrimazole vaginal expansion suppository in the treatment of mild and moderate vulvovaginal candidiasis in terms of efficacy, patient satisfaction, side effects, and recurrence rate. Methods: This study was jointly conducted by 5 hospitals from August 2017 to October 2018, patients with mild and moderate vulvovaginal candidiasis confirmed by fungal culture and symptoms scores were selected. They were randomized to experimental group and control group as 1â¶1 ratio. In the experimental group (n=105), the subjects applied clotrimazole vaginal expansion suppository (150 mg) daily at night for 7 days. In the control group (n=106), the subjects used a single dose of clotrimazole vaginal tablet (500 mg). Follow-ups were performed at (8±3) and (30±5) days after the discontinuation of the drugs, respectively. The difference in clinical symptoms and signs scores was used to evaluate the improvement of clinical symptoms, and the patient's satisfaction and side effects were recorded. Results: At the first follow-up, the experimental group and control group were followed up by fungal culture on the cure rate [66.7% (70/105) versus 63.2% (67/106), P>0.05] and total effective rate [98.1% (103/105) versus 99.1% (105/106), P>0.05], the differences were not statistically significant. At the second follow-up, the recurrence rates of the experimental group and the control group were 5.7% (4/70) and 14.9% (10/67), respectively, with no significant difference (P>0.05). In the evaluation of patient satisfaction, the leakage of the drug in the experimental group was significantly better than that in the control group (P<0.01). The side effects mainly included vaginal stimulation, itching and burning sensation, and there was no statistical difference between the two groups (χ2=1.070, P=0.586). Conclusions: In the treatment of mild and moderate vulvovaginal candidiasis, clotrimazole vaginal expansion suppository is no less effective than clotrimazole vaginal tablet, and there is no significant difference in the recurrence rate between the two. In terms of patient satisfaction, clotrimazole vaginal expansion suppository is superior to clotrimazole vaginal tablet.

We report the first measurement of the double-differential and total muon neutrino charged current inclusive cross sections on argon at a mean neutrino energy of 0.8 GeV. Data were collected using the MicroBooNE liquid argon time projection chamber located in the Fermilab Booster neutrino beam and correspond to 1.6×10^{20} protons on target of exposure. The measured differential cross sections are presented as a function of muon momentum, using multiple Coulomb scattering as a momentum measurement technique, and the muon angle with respect to the beam direction. We compare the measured cross sections to multiple neutrino event generators and find better agreement with those containing more complete treatment of quasielastic scattering processes at low Q^{2}. The total flux integrated cross section is measured to be 0.693±0.010(stat)±0.165(syst)×10^{-38} cm^{2}.
