Abstract
The efficacy and safety of traditional Chinese medicine and acupuncture in the treatment of kidney-deficiency and bloodstasis perimenopausal sleep disorders were evaluated. A total of 67 subjects who completed the study were randomly divided into two groups. The traditional Chinese medicine group was orally given Bushen Huoxue Anshen Fang,and the acupuncture group was given acupuncture treatment. Both groups were treated for three consecutive courses of treatment,with a course of treatment of 30 days. The changes of PSQI score,improved Kupperman score,TCM syndromes,serum sex hormone,coagulation,routine blood and urine,liver and kidney function and electrocardiogram were observed before and after treatment. After treatment,the total effective rates of Chinese medicine group and acupuncture group were similar or respectively 91. 43% and 87. 50%. The scores of PSQI,improved Kupperman and TCM syndromes in both groups decreased significantly( P<0. 05). The effect of improving Kupperman score in TCM group was better than that in acupuncture group( P< 0. 01). The effect of improving PSQI and TCM syndromes was similar to that in acupuncture group. The levels of serum FSH and LH were decreased in both groups( P<0. 05),but with no significant difference between the two groups; the level of serum E2 was increased in both groups,but with no significant difference. Compared with before treatment,PT was increased in traditional Chinese medicine group( P<0. 05),but with no significant difference in APTT,TT and FIB before and after treatment; PT and TT were prolonged in acupuncture group( P<0. 05),but with no significant difference in APTT and FIB before and after treatment. The effect of improving PT and TT in the acupuncture group was better than that in the traditional Chinese medicine group( P<0. 05). The results showed that TCM and acupuncture had similar therapeutic effects on perimenopausal sleep disorder of kidney deficiency and blood stasis type,and were safe and reliable. The mechanism was related to the improvement of serum FSH and E2 levels.

Abstract
Over the past decade, breakthrough has been made on myopia progression control with a lot of evidence from clinical trials, but the effective clinical application of many of them remained immature. Though refraction clinics have been set up in many specialized hospitals offering spectacles to correct refractive error, there was few protocol or standard of treatment for reducing myopia progression. This commentary reviews the latest and essential publications and presents critical advice on applying the research findings to clinical practice. (Chin J Ophthalmol, 2019, 55: 89-92).

Abstract
Objective: To analyze clinical characteristics of severe community-acquired pneumonia during pregnancy and its outcomes, and to explore the relevant risk factors. Methods: From September 2012 to September 2017, 324 398 pregnancies admitted in 7 tertiary hospitals were included. Clinical data of 33 cases of pregnancies with severe community-acquired pneumonia (severe pneumonia group) and 214 cases of pregnancies with common community-acquired pneumonia (control group) were reviewed retrospectively, including the clinical information, manifestations, laboratory examinations and pregnancy outcomes. Relevant risk factors were analyzed by multivariate logistic regression analysis. Results: (1) General data: pregnancies with severe community-acquired pneumonia accounted for 0.010% (33/324 398) of hospitalized pregnancies, the gestational age of two groups were (28±8) and (23±8) weeks, body mass index were (21.7±2.1) and (25.5±3.4) kg/m(2), rate of low income were 54.5% (18/33) and 31.8% (68/214) , respectively. The differences between two groups were all statistically significant (all P<0.05). No significant differences were found in age, pregnancy and parity times, rate of main pregnant complications such as diabetes and hypertension, educational level, asthma and onset seasons between two groups (all P>0.05). (2) Clinical data: the severe pneumonia group had significantly higher incidence of fever [100.0% (33/33) vs 75.2% (161/214) ], shortness of breath (90.9% vs 16.8%) compared with the control group (all P<0.05) .The median peripheral leukocytes counts were 12.3×10(9)/L and 10.2×10(9)/L, the hemoglobin level were (84±18) and (107±14) g/L,the albumin level were (26±4) and (37±3) g/L, the median serum urea nitrogen level were 3.7 and 2.4 mmol/L, the serum creatinine level were (72±25) and (45±11) μmol/L, respectively in two groups. The differences were all statistically significant (all P<0.05). No significantly statistical differences were found in coagulation indicator and cardiac function between two groups (all P>0.05). (3) Treatments: in severe pneumonia group, 12 patients (36.4%,12/33) needed invasive mechanical ventilation, 9 patients (27.3%,9/33) needed non-invasive mechanical ventilation, average time of mechanical ventilation was (7±4) days;8 patients (24.2%,8/33) with septic shock needed vasoactive drugs. However, there was no patient in control group needing mechanical ventilation and vasoactive drugs. (4) Pregnant outcomes: one patient (3.0%,1/33) died in the severe pneumonia group, while no death occurred in the control group. The hospital stay between two groups were (15.1±4.1) and (7.0±1.9) days, the rates of abortion and stillbirth between two groups were 42.4% (14/33) and 3.3% (7/214) , the rates of premature were 10/19 and 6.3% (13/207) , the rates of cesarean were 15/19 and 43.0% (89/207) , the rates of low birth weight newborn were 17/19 and 14.0% (29/207) , the rates of infected newborn were 15/19 and 10.1% (21/207) , the birth weights were (2 165±681) and (3 102±400) g, respectively. The differences between two groups were all statistically significant (all P<0.05). (5) Multivariate logistic regression analysis demonstrated that anemia, low body mass index, hypoproteinemia were risk factors for severe pneumonia in pregnancy (all P<0.05) . Conclusions: Pregnancy with severe community-acquired pneumonia may be complicated by multiple organ dysfunctions, lead to adverse outcomes. Anemia, malnutrition are risk factors for pregnancy with severe pneumonia. Active and effective treatment may improve its prognosis.

Abstract
We report a measurement of electron antineutrino oscillation from the Daya Bay Reactor Neutrino Experiment with nearly 4 million reactor ν[over ¯]_{e} inverse β decay candidates observed over 1958 days of data collection. The installation of a flash analog-to-digital converter readout system and a special calibration campaign using different source enclosures reduce uncertainties in the absolute energy calibration to less than 0.5% for visible energies larger than 2 MeV. The uncertainty in the cosmogenic ^{9}Li and ^{8}He background is reduced from 45% to 30% in the near detectors. A detailed investigation of the spent nuclear fuel history improves its uncertainty from 100% to 30%. Analysis of the relative ν[over ¯]_{e} rates and energy spectra among detectors yields sin^{2}2θ_{13}=0.0856±0.0029 and Δm_{32}^{2}=(2.471_{-0.070}^{+0.068})×10^{-3} eV^{2} assuming the normal hierarchy, and Δm_{32}^{2}=-(2.575_{-0.070}^{+0.068})×10^{-3} eV^{2} assuming the inverted hierarchy.

Abstract
OBJECTIVES To derive the probability equation given by STR allele frequencies of identity by state (IBS) score shared by unrelated individual pairs. METHODS By comparing the STR genotypes of two unrelated individuals, three mutually exclusive combinations could be obtained: (1) sharing 2 identical alleles, a₂=1, otherwise a₂=0; (2) sharing 1 identical allele, a₁=1, otherwise a₁=0; (3) sharing 0 identical allele, a₀=1, otherwise a₀=0. And the IBS score of the one STR locus in this unrelated individual pair could be given by the formula: ibs=2a₂+a₁. The probability of a₂=1 (p₂), a₁=1 (p₁) and a₀=1 (p₀) were derived and expressed in powers of the allele frequencies. Subsequently, for a genotyping system including n independent STR loci, the characteristics of binomial distribution of IBS score shared by a pair of unrelated individuals could be given by p₂l and p₁l (l=1, 2, …, n). RESULTS All the general equations of p₂, p₁ and p₀ were derived from the basic conceptions of a₂, a₁ and a₀, respectively. Given fi (i=1, 2, …, m) as the ith allele frequency of a STR locus, the general equations of p₂, p₁ and p₀ could be respectively expressed in powers of fi: [Formula: see text],[Formula: see text] and [Formula: see text]. The sum of p₂, p₁ and p₀ must be equal to 1. Then, the binomial distribution of IBS score shared by unrelated individual pairs genotyped with n independently STR loci could be written by: IBS~B(2n, π), and the general probability, π, could be given by the formula: [Formula: see text]. CONCLUSIONS In the biological full sibling identification, the probability of null hypothesis corresponding to any specific IBS score can be directly calculated by the general equations presented in this study, which is the basement of the evidence explanation.

Abstract
Bocaparvovirus infections of humans and both wild and domestic animals have been widely reported around the world. In this study, we detected and genetically characterized porcine bocavirus (PBoV) carried by murine rodents (Rattus norvegicus, Rattus tanezumi, and Rattus losea) and house shrews (Suncus murinus) in China. Between May 2015 and May 2017, 496 murine rodents and 23 house shrews were captured in four Chinese provinces. Nested polymerase chain reaction was used to investigate the prevalence of PBoV in throat swab, faecal and serum samples. A total of 7.5% (39/519) throat swab samples, 60.5% (309/511) faecal samples, and 22.9% (52/227) serum samples were PBoV-positive. The prevalence among R. norvegicus and R. tanezumi was higher than that among R. losea and house shrews. PBoV-positive samples were found in all four provinces. Phylogenetic analysis based on partial viral capsid protein 1/2 (VP1/VP2) showed that sequences obtained in this study formed a novel group (PBoV G4). In addition, five near full-length PBoV genomes (4,715-4,798 nt) were acquired. These genomes encoded two non-structural proteins, NS1 (1,908 nt in four genomes and 1,923 nt in the remaining genome) and NP1 (600 nt), and the structural proteins, VP1/VP2 (1,851 nt). Phylogenetic analysis showed that PBoV G4 is distinct from rodent, human, and other bocaviruses. In conclusion, PBoV G4 prevalence was high among two common murine rodents in China, and the pathogenecity of PBoV G4 need to be further clarified.

Abstract
Perimenopausal syndrome refers to a series of physical and mental symptoms, caused by the fluctuation of the sex hormones in the menopause, which is one of the common diseases in gynecology. The incidence of sleep disorders in perimenopausal women is increasing significantly. Both Chinese medicine and Western medicine are trying to exploring its pathologic mechanism to find the safe and effective methods of treatment. Menopausal sleeping disorder is the same as the perimenopause syndrome and insomnia category in traditional Chinese medicine. Kidney deficiency is the basic characteristic of perimenopause, whether kidney essence, kidney Qi, kidney Yin or kidney Yang can lead to blood stasis. It is believed that this disease results from kidney deficiency in the root and blood stasis in the tip, and on this basis women affected by many factors will result in disharmony between heart and kidney. In clinical practice, The method of tonifying kidney and activating blood applied to treat perimenopause syndrome with insomnia was testified to be effective. Therefore the author thought that kidney deficiency and blood stasis and disharmony between heart and kidney were the key factors of patients with insomnia in perimenopause.

Abstract
Objective: To evaluate the value of open surgery repair and endovascular aortic repair in the treatment of abdominal aortic aneurysm which implicate visceral arteries. Methods: From January 2012 to October 2016, 26 patients were reviewed. According to the treatment, they were divided into open surgery group (n=7) and endovascular repair group(n=19). Then, the characteristics and relative data of follow-up of the two groups were analysis. Results: In open surgery group, there were 7 patients. All of them were men, median age 58(41-62) years and 1 patient were older than 75 years. And in endovascular repair group, there were 19 patients(14 men) of median age 72(66-76) years, 8 patients were older than 75 years. Patients in endovascular repair group were significantly older than who were in open surgery group (Z=-13.06, P<0.05). Complications of open surgery group and endovascular repair group were 57.14% and 15.79% respectively. There was no statistically significant difference (χ(2)=3.13, P>0.05). During follow-up, the diameters of aneurysm which planted stents were smaller than before. Conclusions: In the treatment of abdominal aortic aneurysm implicated visceral arteries, open surgery is mainly suitable for the patients with low-risk. But the rate of complications was high. By contrast, endovascular aortic repair with small trauma and high safety, has becoming the first choice.

Abstract
The Daya Bay experiment has observed correlations between reactor core fuel evolution and changes in the reactor antineutrino flux and energy spectrum. Four antineutrino detectors in two experimental halls were used to identify 2.2 million inverse beta decays (IBDs) over 1230 days spanning multiple fuel cycles for each of six 2.9 GW_{th} reactor cores at the Daya Bay and Ling Ao nuclear power plants. Using detector data spanning effective ^{239}Pu fission fractions F_{239} from 0.25 to 0.35, Daya Bay measures an average IBD yield σ[over ¯]_{f} of (5.90±0.13)×10^{-43} cm^{2}/fission and a fuel-dependent variation in the IBD yield, dσ_{f}/dF_{239}, of (-1.86±0.18)×10^{-43} cm^{2}/fission. This observation rejects the hypothesis of a constant antineutrino flux as a function of the ^{239}Pu fission fraction at 10 standard deviations. The variation in IBD yield is found to be energy dependent, rejecting the hypothesis of a constant antineutrino energy spectrum at 5.1 standard deviations. While measurements of the evolution in the IBD spectrum show general agreement with predictions from recent reactor models, the measured evolution in total IBD yield disagrees with recent predictions at 3.1σ. This discrepancy indicates that an overall deficit in the measured flux with respect to predictions does not result from equal fractional deficits from the primary fission isotopes ^{235}U, ^{239}Pu, ^{238}U, and ^{241}Pu. Based on measured IBD yield variations, yields of (6.17±0.17) and (4.27±0.26)×10^{-43} cm^{2}/fission have been determined for the two dominant fission parent isotopes ^{235}U and ^{239}Pu. A 7.8% discrepancy between the observed and predicted ^{235}U yields suggests that this isotope may be the primary contributor to the reactor antineutrino anomaly.

Abstract
OBJECTIVE To investigate the image features, categories, and clinical significances of Pneumoconiosis Ш with large shadow. METHODS The research is based on the analysis of image features of 168 pneumoconiosis Ш patients who are directly diagnosed by qualified medical professionals in our institution. These image features are large shadows bigger than 2 cm×1 cm which can be observed by high kilovolt chest radiographs, DR chest radiography and chest CT scan. RESULTS Large shadows bigger than 2×1 cm show noticeable imaging characteristics, like distribution of superior and middle lung regions (95.2%) , irregular shapes (97.6%) , splayed or sausage like changes on both sides perpendicular with ribs (89.2%) , small shadows of pneumoconiosis (98.8%) , and convergence of large shadow to hilum or mediastinal (53.6%). CT scan is significantly better than DR radiography on detection rate of focal emphysema, focal cavities and swollen lymph node of mediastinal. CONCLUSION Combining the image features of high kilovolt chest radiographs, DR chest radiographs and CT scan are the main methods to identify the shadows, and thus direct diagnose pneumoconiosis Ш; CT scan plays an important role in differential diagnosis.

Abstract
The prevention of chemotherapy‐induced nausea and vomiting was one of the most challenging supportive care issues in oncology, especially to highly emetogenic chemotherapy (HEC). A total of 645 patients were randomized into fosaprepitant group (fosaprepitant/placebo 150 mg d1 in combination with granisetron and dexamethasone) or aprepitant group (aprepitant/placebo 125 mg d1; 80 mg d2‐d3 plus granisetron and dexamethasone).The primary endpoint was the percentage of patients who had a complete response (CR) over the entire treatment course (0–120 hr, overall phase [OP]). It was assessed by using a non‐inferiority model, with a non‐inferiority margin of 10%. The difference of the CR rate was compared between two groups with chi‐square analysis. Six hundred and twenty‐six patients were included in the per protocol analysis. The percentage of patients with a CR in the fosaprepitant group was not inferior to that in the aprepitant group (90.85% versus 94.17%, p = .1302) during OP. Whether the cisplatin‐based chemotherapy or not, the CR rate of the fosaprepitant group was not inferior to that of the aprepitant group. Both regimens were well tolerated. The most common adverse event was constipation. Fosaprepitant provided effective and well‐tolerated control of nausea and vomiting associated with HEC in Chinese patients.

Abstract
Mineral salt bricks are often used in cow raising as compensation for mineral losses to improve milk yield, growth, and metabolic activity. Generally, effects of minerals are partially thought to result from improvement of microbial metabolism, but their influence on the rumen microbiota has rarely been documented to date. In this study, we investigated the response of microbiota to mineral salt in heifer and adult cows and evaluated ruminal fermentation and enteric methane emissions of cows fed mineral salts. Twelve lactating Holstein cows and twelve heifers fed a total mixed ration (TMR) diet were randomly allocated into two groups, respectively: a treatment group comprising half of the adults and heifers that were fed mineral salt and a control group containing the other half fed a diet with no mineral salt supplement. Enteric methane emissions were reduced by 9.6% (P < 0.05) in adults ingesting a mineral salt diet, while concentrations of ruminal ammonia, butyrate, and propionate were increased to a significant extent (P < 0.05). Enteric methane emissions were also reduced in heifers ingesting a mineral salt diet, but not to a significant extent (P > 0.05). Moreover, the concentrations of ammonia and volatile fatty acids (VFAs) were not significantly altered in heifers (P > 0.05). Based on these results, we performed high-throughput sequencing to explore the bacterial and archaeal communities of the rumen samples. Succiniclasticum and Prevotella, two propionate-producing bacteria, were predominant in samples of both adults and heifers. At the phylotype level, mineral salt intake led to a significant shift from Succiniclasticum to Prevotella and Prevotellaceae populations in adults. In contrast, reduced abundance of Succiniclasticum and Prevotella phylotypes was observed, with no marked shift in propionate-producing bacteria in heifers. Methanogenic archaea were not significantly abundant between groups, either in adult cows or heifers. The shift of Succiniclasticum to Prevotella and Prevotellaceae in adults suggests a response of microbiota to mineral salt that contributes to higher propionate production, which competes for hydrogen utilized by methanogens. Our data collectively indicate that a mineral salt diet can alter interactions of bacterial taxa that result in enteric methane reduction, and this effect is also influenced in an age-dependent manner.

Abstract
Searches for a light sterile neutrino have been performed independently by the MINOS and the Daya Bay experiments using the muon (anti)neutrino and electron antineutrino disappearance channels, respectively. In this Letter, results from both experiments are combined with those from the Bugey-3 reactor neutrino experiment to constrain oscillations into light sterile neutrinos. The three experiments are sensitive to complementary regions of parameter space, enabling the combined analysis to probe regions allowed by the Liquid Scintillator Neutrino Detector (LSND) and MiniBooNE experiments in a minimally extended four-neutrino flavor framework. Stringent limits on sin^{2}2θ_{μe} are set over 6 orders of magnitude in the sterile mass-squared splitting Δm_{41}^{2}. The sterile-neutrino mixing phase space allowed by the LSND and MiniBooNE experiments is excluded for Δm_{41}^{2}<0.8 eV^{2} at 95% CL_{s}.
