Generalized headache among Chinese climacteric women: findings from a prospective cohort

OBJECTIVE

This study aimed to prospectively identify the prevalence of generalized headache and associated risk factors in Chinese midlife women.

METHODS

We identified 411 qualified women from a Chinese urban community, contributing a total of 2544 surveys. The presence of generalized headache was measured. Climacteric symptoms and other risk factors were evaluated by generalized estimating equations.

RESULTS

The prevalence of headache complaints is associated with menopausal stages. Perimenopausal women have relatively high prevalence of headache symptoms, especially stage +1a women (59.0%) compared to late postmenopausal women (37.8%), although menopause stages were not statistically significant in the multivariate analysis. Women who had headache at baseline and depression were much more likely to have headache during menopause. According to the univariate and multivariate analyses in women without headache at baseline, starting menopausal status, insomnia, sweats, and depression were independently associated with newly developed headache.

CONCLUSIONS

Symptoms of generalized headache were less prevalent in late postmenopausal women. Our findings highlight the association between headache and climacteric changes.

Absence of strict monogamy in the Eurasian jackdaw, Coloeus monedula

The Eurasian Jackdaw is thought to be archetypically monogamous, but recent tagging research uncovered extra-pair copulations in the species. Here we examined extra-pair paternity (genetic monogamy) in Eurasian jackdaws breeding in the Judean Hills, Israel, at the global edge of the species range, using a set of highly polymorphic molecular microsatellites. We found roughly a sixth of nests sampled showed deviations from monogamy, more than previously found in DNA fingerprinting studies of jackdaws, suggesting a mixed mating strategy in this population. These findings support the trend of extra-pair paternity in avian species, even when social monogamy remains the rule, and highlight the importance of continued study of species throughout their geographical range.

Tunable interfacial Dzyaloshinskii-Moriya interaction in symmetrical Au/[Fe/Au]n multilayers

The interfacial Dzyaloshinskii-Moriya interaction (i-DMI) has been exploited in as-made symmetrical Au/[Fe/Au]n structures. By tailoring the chirality of the i-DMI at the Au/Fe interface, an overall enhancement of the i-DMI can be obtained in such a symmetrical structure. Furthermore, the tunability of the i-DMI was realized by changing the stacking number n. Compared to the top of Fe, a large tensile stress at the bottom of Fe due to lattice mismatch was responsible for the chirality change in the sub/Au/Fe system. Layer-resolved DMI calculations revealed that the sign of the spin-orbit coupling (SOC) energy was changed for Au near the interface of Au/Fe under tensile stress, subsequently reversing the chirality of the i-DMI from left-handed to right-handed. Our findings provide a simplest way to tune the i-DMI in a multilayer system, further benefiting the application of skyrmion-based devices.

Setting the new FRAX reference threshold without bone mineral density in Chinese postmenopausal women

PURPOSE

Despite the large number of osteoporosis patients in China, the diagnosis and treatment rates remain low. The Fracture Risk Assessment Tool (FRAX) can be used to effectively evaluate fracture risk. In this study, we explored the Chinese-specific thresholds of FRAX without the T-score.

METHODS

In all, 264 postmenopausal women aged > 50 years were randomly recruited from community-medical centers. All subjects completed self-reported questionnaires, BMD measurements, and spinal radiographs. The 10-year hip and major osteoporotic fracture risks were calculated by FRAX. A new threshold for both 10-year hip and major osteoporotic fracture risk was explored with receiver operating characteristic (ROC) curve analysis.

RESULTS

Overall, 92 subjects were diagnosed with osteoporosis. Among them, 14 participants with T-score > - 2.5 were diagnosed with osteoporosis based on clinical fractures. ROC analysis showed the cut-off value of the 10-year hip osteoporotic fracture for detecting osteoporosis was 0.95%, while that of 10-year major osteoporotic fracture was 4.95%. The sensitivity and specificity of the 10-year hip osteoporotic fracture probability for detecting osteoporosis were 0.86 and 0.59, respectively, while the guideline-recommended threshold had a sensitivity of 0.49 and specificity of 0.83. The sensitivity and specificity of the 10-year major osteoporotic fractures with the new threshold were 0.76 and 0.69, respectively, while the recommended threshold had a sensitivity of 0 and specificity of 1.

CONCLUSION

Current guideline-recommended FRAX thresholds without BMD showed low sensitivity. Therefore, 10-year osteoporotic hip fracture probability ≥ 0.95% and 10-year osteoporotic major fracture probability ≥ 4.95% are recommended as the new thresholds.

[Incidence and mortality of corpus uteri cancer in China, 2015]

Objective: To estimate the incidence and mortality of corpus uteri cancer in China, 2015. Methods: Quality audit and evaluation of the data from 2015 cancer registration reported by 501 cancer registries were conducted, and 368 cancer registries were included in the analysis. The incidence rate and mortality rate of corpus uteri cancer were calculated according to the factors of the region (urban, rural, east, central, western), sex and age groups. The incidence and mortality of corpus uteri cancer with the 2015 population were estimated. Chinese standard population in 2000 and world Segi's population were used for the calculation of age-standardized rates (ASR) of incidence and mortality. Results: In 2015, 368 cancer registries included in the analysis covered a total of 309 553 499 populations in China, accounting for 22.52% of the national population. It is estimated that there were about 68 900 new cases of corpus uteri cancer in 2015, the incidence rate was 10.28/10(5), age-standardized incidence rates by Chinese standard population (ASR China) and world standard population (ASR world) were 6.86/10(5) and 6.66/10(5), respectively. The incidence rate of urban area (11.35/10(5)) was higher than that of rural area (8.90/10(5)), and the incidence of eastern region (12.12/10(5)) was higher than the central region (9.94/10(5)) and the western region (8.25/10(5)). It is estimated that in 2015, there were about 16 000 deaths of corpus uteri cancer, the mortality rate was 2.39/10(5), ASR China was 1.49/10(5), ASR world was 1.47/10(5). The mortality in urban areas (2.40/10(5)) is close to rural areas (2.39/10(5)); the mortality in central areas (2.55/10(5)) was higher than the eastern areas (2.32/10(5)) and the western areas (2.31/10(5)). Conclusions: In China, the incidence of corpus uteri cancer is on the rise and has a trend of youth, the burden of disease is gradually increasing, which threatens the health of women. Targeted prevention and control measures should be carried out in the different regions.

The effective coupling coefficient for a completed PIN-PMN-PT array

The computation of the electromechanical coupling coefficient (EMCC) of a fully assembled medical ultrasound transducer array is directly computed with closed form expressions. The Levenberg-Marquardt non-linear regression algorithm (LMA) is employed to help confirm the EMCC calculated prediction (k_EFF) and provide statistical insights. The complex electrical impedance spectra of a 1-3 composite array with two matching layers operating at a 3.75 MHz center frequency using PIN-PMN-PT single crystal material is measured in air both before and after oven heating at 160 °C for 15 min. The oven heating produces changes in the EMCC of -4.9%, clamped dielectric constant of -11%, and effective transducer longitudinal velocity of -2.5%. Utilizing the pre- and post-heating array impedance data, the calculated EMCC values from the new closed form expressions agree well with the complete KLM model based LMA, and also exhibit approximately one tenth the error as compared to the formulas for a flat, unloaded transducer.

Model-based convolutional neural network approach to underwater source-range estimation

This paper is part of a special issue on machine learning in acoustics. A model-based convolutional neural network (CNN) approach is presented to test the viability of this method as an alternative to conventional matched-field processing (MFP) for underwater source-range estimation. The networks are trained with simulated data generated under a particular model of the environment. When tested with data simulated in environments that deviate slightly from the training environment, this approach shows improved prediction accuracy and lower mean-absolute-error (MAE) compared to MFP. The performance of this model-based approach also transfers to real data, as demonstrated separately with field data collected in the Beaufort Sea and off the coast of Southern California. For the former, the CNN predictions are consistent with expected source range while for the latter, the CNN estimates have lower MAE compared to MFP. Examination of the trained CNNs' intermediate outputs suggests that the approach is more constrained than MFP from outputting very inaccurate predictions when there is a slight environmental mismatch. This improvement appears to be at the expense of decreased certainty in the correct source range prediction when the environment is precisely modeled.

MiR-503 Contributes to Glucocorticoid Sensitivity in Acute Lymphoblastic Leukaemia via Targeting WNT3A

Abnormal accumulation of lymphoblasts in the blood and bone marrow is the main characteristic of acute lymphoblastic leukaemia (ALL). Glucocorticoids are effective drugs for ALL, while glucocorticoid resistance is an obstacle to ALL therapy. MicroRNAs (miRNAs) are implicated in the drug resistance and modulate the response of ALL to glucocorticoids. The role of miR-503 in glucocorticoid sensitivity of ALL was investigated in this study. Firstly, T-leukaemic cells were isolated from patients with ALL. The human ALL cell line (CCRF/CEM) was incubated with dexamethasone to establish a glucocorticoid- resistant ALL cell line (CCRF/CEM-R). Data from MTT showed that IC⁵⁰ (50% inhibitory concentration) of dexamethasone in T-leukaemic cells isolated from glucocorticoid-resistant ALL patients or CCRF/CEM-R was increased compared with IC50 in T-leukaemic cells isolated from glucocorticoid- sensitive ALL patients or CCRF/CEM. MiR- 503 was down-regulated in glucocorticoid-resistant leukaemic cells and CCRF/CEM-R. Secondly, overexpression of miR-503 sensitized CCRF/CEM-R to dexamethasone. Moreover, over-expression of miR- 503 also promoted the sensitivity of ALL cells to dexamethasone. Thirdly, miR-503 bound to WNT3A mRNA and negatively regulated the expression of WNT3A. Over-expression of miR-503 reduced protein expression of nuclear β-catenin, and over-expression of WNT3A attenuated the miR-503 overexpression- induced decrease in nuclear β-catenin. Lastly, the over-expression of miR-503-induced increased sensitivity of ALL-resistant cells and CCRF/ CEM-R to dexamethasone was attenuated by overexpression of WNT3A. In conclusion, miR-503 targeted WNT3A mRNA to sensitize ALL cells to glucocorticoids through inactivation of the Wnt/β-catenin pathway.

Temporal and spatial characteristics of the Beaufort Sea ambient noise environment

Underwater ambient noise from the Beaufort Sea, collected in March 2016, is analyzed to investigate the effect that environmental changes in the region have on the spatial and temporal characteristics of the ice-generated ambient noise. In particular, the influx of warm Pacific water, so called the Beaufort Lens, has dramatically altered the level and vertical directionality of ambient noise, creating a low noise zone in the ∼75-250 m depth interval with a noise notch at low grazing angles. It is also demonstrated how the observed noise vertical directionality is consistent with ice-mechanical activity along an active pressure ridge ∼30-50 km from the recording array, as shown by satellite imagery. The discrete ranges to this ice activity explain the peak arrival angles between -10 to -15 degrees in noise vertical directionality, as well as the horizontal noise notch. Transient noise events associated with the ice activity are analyzed using an image processing approach with hierarchical clustering applied to the recorded spectrograms. The observed events are grouped into three categories-short-time-broadband, long-time-narrowband, and long-time-broadband-each likely generated through a different mechanism by the ice cover. The spectral and temporal distribution of these transients are discussed.

En bloc resection and reconstruction in patients with advanced recurrent nasopharyngeal carcinoma and radiation-induced sarcoma of the head and neck

The purpose of this study was to assess the outcomes of patients with advanced recurrent nasopharyngeal carcinoma (rNPC) and radiation-induced sarcoma of the head and neck (RISHN) who underwent en bloc resection and reconstruction. Fifty-two patients with advanced rNPC (n=36) and RISHN (n=16) underwent en bloc resection and reconstruction with an extended lower vertical trapezius island myocutaneous flap (TIMF). En bloc resection of the tumour (including craniomaxillofacial resections and neck resections) and major defect restoration was successful in all patients. TIMF survival was 92.3%. Postoperative mild hemiplegia occurred in one patient with rNPC. In total, 20 patients (55.5%) in the rNPC group and seven (43.8%) in the RISHN group recovered with no signs of disease at follow-up. No statistically significant difference in recovery status was observed between the rNPC and RISHN groups. En bloc resection of the tumour, including dissection of the carotid artery, ensured microscopic clearance of the disease; this is a viable treatment option for patients with advanced rNPC or RISHN without distant metastasis. The extended vertical lower TIMF is a large, straightforward, and reliable flap for repairing the resultant major defects in the craniomaxillofacial or neck region.

Oral Health Inequalities in 0-17-year-old Children Referred for Dental Extractions Under General Anaesthesia in Wolverhampton, 2013-2017

OBJECTIVE

Describe the inequalities in oral health in children treated in a hospital located in a deprived urban area in the UK.

RESEARCH DESIGN

Case-note review of 1911 0-17-year-olds who underwent dental extractions under a general anaesthetic (DGA).

MAIN OUTCOME MEASURES

Associations between Age, Ethnicity, Year-of-Treatment and Index of Multiple Deprivation (IMD) with the number of teeth extracted. Analysis used multilevel modelling assuming a Poisson distribution.

RESULTS

Mean number of teeth extracted was higher in the youngest children treated aged 0-5 years (relative risk coefficient, (RR=exp(β)=1.39; 95% CI 1.24 to 1.56) compared to those aged 6-17 years and in 'Other Whites' (predominantly immigrants from Eastern Europe) (RR=exp(β)=1.34; 95% CI 1.25 to 1.43), 'South Asians' (RR=exp(β)=1.15; 95% CI 1.08 to 1.23) but fewer in the 'Black' ethnic group (RR=exp(β)=0.85; 95% CI 0.76 to 0.95). DGA increased during the study with more teeth extracted in 2015, 2016 and 2017 (RR=exp(β)=1.12, 95% CI 1.22, 1.25) and with a negative gradient in the rate of DGA's (per decile) in children from the most deprived to most affluent locations (RR=exp(β)=0.98; 95% CI 0.97 to 0.99).

CONCLUSIONS

Significant oral health inequalities exist in children from a deprived urban area in the UK. A preventive approach to children's oral health is needed to reduce such inequalities, including public health and healthcare agencies to informing parents of children whose first language is not English about dental caries.

Diagnostic efficacy of contrast-enhanced ultrasound versus MRI Liver Imaging Reporting and Data System (LI-RADS) for categorising hepatic observations in patients at risk of hepatocellular carcinoma

AIM

To investigate the diagnostic efficacy of the contrast-enhanced ultrasound Liver Imaging Reporting and Data System (CEUS LI-RADS) for categorising hepatic observations in patients at risk of hepatocellular carcinoma (HCC) compared with magnetic resonance imaging (MRI) LI-RADS.

MATERIALS AND METHODS

CEUS and MRI data were analysed retrospectively according to the LI-RADS scheme. Follow-up results and pathological findings served as the reference standard. Receiver operating characteristic (ROC) curve analysis was used to reveal the area under the curve (AUC). The sensitivity, specificity, accuracy, and positive (PPV) and negative predictive values (NPV) of LR-5 for determining HCC were calculated. The intra-observer agreement of CEUS LI-RADS was also evaluated.

RESULTS

Eighty-four patients with 86 liver observations were enrolled. Forty-two observations were classified as LR-5 by CEUS and MRI, respectively. Based on the reference standard, 53 nodules were HCC. The AUCs were 0.876 for CEUS and 0.873 for MRI, without a significant difference (Z=0.050, p=0.960). The sensitivity, specificity, PPV, NPV, and accuracy of LR-5 was 75.47%, 93.94%, 95.24%, 70.45%, 82.56% with CEUS and 73.58%, 90.9%, 92.86%, 68.18%, 80.23% with MRI, respectively. There was a significant difference in specificity between CEUS and MRI (p=0.006). There was almost perfect agreement for arterial phase hyperenhancement (k=0.870), substantial agreement for washout (k=0.765) and CEUS LI-RADS category (k=0.787).

CONCLUSION

The CEUS LI-RADS scheme is an effective diagnostic tool for HCC with substantial intra-observer reliability. The diagnostic performance of CEUS LI-RADS for determining HCC was comparable to MRI LI-RADS, and the specificity of CEUS LR-5 was significantly higher.

[Progress in research of Fusobacterium nucleatum and upper gastrointestinal cancer]

With the development of multi-omics and high throughput sequencing technology, studies have shown that the disorder of microbiota is related to various cancers. Nevertheless, the research on the relationship between upper digestive tract cancer or precancerous lesions and gastrointestinal microecology is still less. Fusobacterium nucleatum, one of the oral symbiotic bacteria, is also an opportunistic pathogen, which can promote the formation of tumor microenvironment and can be used as a new biomarker for the early detection and early diagnosis of cancer. In this study, by searching CNKI, Wanfang data, PubMed and Embase databases, it was found that the abundance of F. nucleatum in cancer tissues is higher than that in paracancerous tissues and associated with poor prognosis. The research of relationship between F. nucleatum and precancerous lesions needs to be carried out urgently. In addition, the types of specimens, sequencing technology, strain subtypes, carcinogenic mechanism and other directions still need to be explored.

Baicalein inhibits the proliferative activity of human prostate cancer cell line PC3 by downregulating Ezrin

We aimed to elucidate the inhibitory effect of Baicalein on proliferative ability in Prostate cancer (PCa) through downregulating Ezrin. Relative level of Ezrin in PCa tissues and adjacent ones was detected. After PC3 cells were induced with 20 or 40 μM Baicalein, changes in viability, cell cycle progression and apoptosis were assessed. Relative levels of CyclinD1, CDK4, P53 and P21 were examined by quantitative real-time polymerase chain reaction (qRT-PCR). Regulatory effects of Ezrin and Baicalein treatment on PC3 cells were evaluated. Finally, in vivo effects of Ezrin and Baicalein treatment on nude mice bearing PCa were detected. Ezrin was upregulated in PCa tissues relative to adjacent normal ones. Baicalein treatment decreased viability, arrested cell cycle and stimulated apoptosis in PC3 cells. Meanwhile, Baicalein treatment downregulated CyclinD1 and CDK4, while upregulating P53 and P21. Moreover, Ezrin was downregulated in Baicalein-treated PC3 cells. Knockdown of Ezrin synergistically stimulated the effects of Baicalein on cellular phenotypes of PC3 cells. In nude mice bearing PCa, Baicalein treatment decreased tumor volume and tumor weight, which were much more pronounced in those with in vivo knockdown of Ezrin. Baicalein treatment suppresses proliferative ability, arrests cell cycle and stimulates apoptosis in PCa cells through downregulating Ezrin.

Prognostic value of age-adjusted d-dimer cutoff thresholds in patients with myocardial infarction treated by percutaneous coronary intervention

Introduction

The association between D-dimer and outcomes of patients with myocardial infarction (MI) remains controversial. Using age-adjusted D-dimer cutoff thresholds significantly improves the accuracy of diagnosis for thrombotic diseases. This study aimed to investigate the prognostic value of age-adjusted D-dimer in MI patients treated by percutaneous coronary intervention (PCI).

Methods

In this observational study, 3614 consecutive patients with MI treated by PCI were retrospectively recruited. The baseline age-adjusted D-dimer threshold was 500 ng/mL, and was calculated as age × 10 in patients older than 50 years. Cox regression was used for outcome analysis. The primary outcome was all-cause death. Discrimination and reclassification were calculated to assess the additional prognostic value of D-dimer when combined with established clinical risk factors and the Global Registry of Acute Coronary Events (GRACE) risk score.

Results

During a median follow-up of 652 days, a total of 194 deaths occurred. High D-dimer level, as defined by age-adjusted thresholds, was an independent predictor for all-cause death (hazard ratio:1.67, 95% confidence interval: 1.23–2.27, P=0.001). Addition of D-dimer level (high or low) significantly improved risk classification for death when combined with established clinical risk factors (net reclassification index [NRI]: 0.601, P<0.001; integrated discrimination improvement [IDI]: 0.011, P=0.046) and GRACE score (NRI: 0.618, P<0.001; IDI: 0.015, P=0.011).

Conclusions

In patients with MI treated by PCI, D-dimer elevation defined by age-adjusted thresholds was an independent predictor for adverse outcomes, and provided additional prognostic value when combined with clinical risk factors and GRACE score.

Association between pre-infarction angina and culprit-lesion morphology in patients with ST-segment elevation myocardial infarction: an optical coherence tomography study

Background

Previous studies reported the cardiac protection effect of pre-infarction angina (PIA) in patients with acute myocardial infarction (AMI). However, the association between PIA and culprit plaques characteristics in AMI patients through optical coherence tomography (OCT)assessment remains unclear.

Purpose

We sought to identify culprit-plaque morphology associated with PIA in patients with ST-segment elevation myocardial infarction (STEMI) using OCT.

Methods

A total of 279 STEMI patients who underwent intravascular OCT of culprit-lesion were included. Baseline clinical data and culprit-plaque characteristics were compared between the PIA group the non-PIA group.

Results

Patients with PIA represented 54.8% of the study population (153 patients). No differences were observed in clinical and angiographic data between two groups, except STEMI onset with exertion was significantly less common in PIA group (24.2% versus 40.5%, P=0.004). Patients with PIA exhibited a significantly lower incidence of plaque rupture (40.5% versus 61.9%, P<0.001) and lipid-rich plaques (48.4% versus 69.0%, P=0.001). The thin-cap fibroatheroma (TCFA) prevalence was lower in PIA group, presenting a thicker fibrous cap thickness, although statistically significant differences were not observed (20.3% versus 30.2%, P=0.070; 129.1±92.0μm versus 111.4±78.1μm, P=0.088; respectively). Multivariate logistic regression analysis indicated that PIA was an independent negative predictor for plaque rupture (odds ratio: 0.44, 95% confidence interval: 0.268–0.725, P=0.001).

Conclusion

STEMI patients with PIA showed a significantly lower prevalence of plaque rupture and lipid-rich plaques in culprit-lesion than non-PIA group, implying different mechanisms of STEMI attack.

Relationship between vasomotor symptoms and metabolic syndrome in Chinese middle-aged women

PURPOSE

This study aimed to find the associations between vasomotor symptoms (VMS) and metabolic syndrome (MetS) in Chinese middle-aged women in a cross-sectional study.

METHODS

A total of 675 participants were recruited from an urban Chinese community. MetS was defined by the 2009 criteria of the Joint Interim Statement. VMS including hot flashes and sweats, blood pressure, weight, height, waist circumference (WC), serum glucose, triglycerides, high-density lipoprotein cholesterol (HDL), low-density lipoprotein cholesterol (LDL), estradiol, and follicle-stimulating hormone (FSH) were collected.

RESULTS

The presence of hot flashes was independently associated with the risk of MetS after adjusting for age, menopausal status, FSH_log, estradiol_log, and physical activity (odds ratio: 1.98, 95% confidence interval: 1.21-3.24, p = 0.006). Both hot flashes and sweats were also independently associated with WC (for hot flashes, p = 0.016; and for sweats, p = 0.007) and triglycerides (for hot flashes, p = 0.041; and for sweats, p = 0.014) significantly. However, VMS were not significantly associated with blood pressure, glucose, HDL, and LDL.

CONCLUSION

Women with hot flashes had a higher risk of MetS. Both hot flashes and sweats were related to a higher amount of central fat indicated by WC and higher triglycerides, but were not related to blood pressure, glucose, and HDL in Chinese women.

[A multicenter, randomized, open and positive parallel controlled clinical study of clotrimazole vaginal expansion suppository and vaginal tablet in the treatment of mild and moderate vulvovaginal candidiasis]

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 1∶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.

Xiangshao granules can relieve emotional symptoms in menopausal women: a randomized controlled trial

OBJECTIVE

This study aimed to investigate the safety and efficacy of Xiangshao granules for treating emotional disorders in perimenopausal and postmenopausal women.

METHODS

The current investigation was a double-blind, randomized, placebo-controlled, multicenter trial that included 300 perimenopausal and postmenopausal Chinese women aged 40-60 years. Participants received either a placebo (n = 150) or Xiangshao granules (n = 150) for 8 weeks. Outcome measures included Hamilton Depression Rating Scale (HAMD) and Hamilton Anxiety Rating Scale (HAMA) scores, which were assessed at baseline, 4 weeks, and 8 weeks. The primary efficacy variables were changes in HAMD and HAMA scores after 8 weeks.

RESULTS

After 8 weeks, the mean HAMD scores decreased from 15.0 to 7.9 in the Xiangshao group and from 16.3 to 10.0 in the placebo group, and the respective mean reductions in HAMA scores were from 16.0 to 8.5 and from 17.1 to 10.9. Clinical improvements in symptoms of both depression and anxiety after 8 weeks differed significantly in the two groups (p < 0.05). The cure rate was significantly higher in the Xiangshao group. There were no significant differences in the rates of adverse events in the two groups.

CONCLUSIONS

Xiangshao granules can relieve symptoms of depression and anxiety significantly and safely.

Precision Constraints for Three-Flavor Neutrino Oscillations from the Full MINOS+ and MINOS Dataset

We report the final measurement of the neutrino oscillation parameters Δm_{32}^{2} and sin^{2}θ_{23} using all data from the MINOS and MINOS+ experiments. These data were collected using a total exposure of 23.76×10^{20} protons on target producing ν_{μ} and ν[over ¯]_{μ} beams and 60.75 kt yr exposure to atmospheric neutrinos. The measurement of the disappearance of ν_{μ} and the appearance of ν_{e} events between the Near and Far detectors yields |Δm_{32}^{2}|=2.40_{-0.09}^{+0.08}(2.45_{-0.08}^{+0.07})×10^{-3}  eV^{2} and sin^{2}θ_{23}=0.43_{-0.04}^{+0.20}(0.42_{-0.03}^{+0.07}) at 68% C.L. for normal (inverted) hierarchy.

[Effects of estradiol on the day of human chorionic gonadotropin administration on adverse perinatal outcomes]

Objective: To investigate the association between estradiol on the day of human chorionic gonadotropin (HCG) administration and birth outcomes among singleton live births following fresh embryo transfers. Methods: Based on the clinical reproduction medicine management system of the First Affiliated Hospital of Nanjing Medical University, this retrospective cohort study collected data of fresh embryo transfer cycles during January 2013 and December 2016, including pregnant women's age, body mass index (BMI), type and cause of infertility, assisted reproductive therapy indicators (fertilization mode, ovulation stimulation protocol, estradiol levels on HCG administration day), adverse birth outcomes[small for gestational age (SGA), premature and low birth weight (LBW)], etc.. A total of 2 060 women with singleton pregnancy (2 061 fresh embryo transfer cycles) were enrolled. Multivariate logistic regression was used to analyze the association between estradiol on HCG administration day and singletons' adverse birth outcomes. Results: The age and BMI of the 2 060 pregnant women were (29.63±3.92) years old and (22.29±2.86) kg/m². Incidences of SGA, premature and LBW were 9.8% (201/2 061), 6.9% (143/2 061) and 3.5% (73/2 061), respectively. After adjusting for confounders, the risk of LBW in 4 000-4 499 pg/ml group was significantly elevated when compared to estradiol<1 500 pg/ml group [OR (95%CI): 4.42 (1.13-17.24)]. A protective effect of premature was observed in estradiol≥4 500 pg/ml group [OR (95%CI): 0.50 (0.25-0.97)]. Conclusion: The high level of estradiol on HCG administration day might be a risk factor for LBW, but a protective factor for premature.
