天比母心

有一种母爱叫信念我家在豫东平原的一个小村落,早年记忆中,母亲白天总是忙着农活,回家时天已黑尽。那时,我还小,躺在母亲怀里,不停地哭着喊饿。我天生脑拙口笨,快上小学了还数不清自己的手指,但母亲很有耐心,常常掰着自己的手数给我看。

Study on Adsorption Behavior of P-nitroaniline from Aqueous Solution by Amphiphilic Hollow Carbonaceous Microspheres

[Objective] The research was aimed to study the adsorption behavior of p-nitroaniline from aqueous solution by porous hollow carbonaceous spheres （PHCSs）.[Method] The effects of pH,temperature and amount of carbonaceous microspheres on adsorption behavior of p-nitroaniline were investigated.[Result] The adsorption amount was affected by temperature slightly,and it decreased with the increase of temperature within a certain range.PHCSs had a higher adsorption capacity as pH was in the range of 2.0-8.0.The adsorption amount of p-nitroaniline was proportional to PHCSs amount within a certain range until it reached a saturation level.The adsorption isotherms of p-nitroaniline appeared to be nonlinear and obeyed to Freundlich equation very well.[Conclusion] The amphiphilic property and the specific chemical functional groups of PHCSs enable them to be a potentially excellent sorbent.

从古代方语差异再论上古晓母和心母相通

上古晓母和心母存在一些谐声、异文、通假现象,中古也有不少异读,前人对这一问题存在一定争议,有的将之归到上古前缀s-。通过整理分析以《经典释文》为代表的音注中不同注家的注解,发现两者与上古前缀s-没有关系,是由语音演变造成的,晓母字以细音为条件演变为心母,汉魏晋时期存在方言的区分,大致上南方读为晓母,北方读为心母。

Relationship between negative emotions and perceived support among parents of hospitalized,critically ill children

Objectives:The purpose of this study was to describe relationships between negative emotions and perceived emotional support in parents of children admitted to the pediatric intensive care unit(PICU).Methods:This cross-sectional descriptive study conducted face-to-face interviews between January 2019 and January 2020.Study variables included depression(PHQ-9 Scale),anxiety(Emotional Distress-Anxiety-Short Form 8a),anger(Emotional Distress-Anger-Short Form 5a),fear(Fear-Affect Computerized Adaptive Test),somatic fear(Fear-Somatic Arousal-Fixed Form),loneliness(Revised 20-item UCLA Loneliness Scale),and perceived emotional support(Emotional Support-Fixed Form).Results:Eighty parents reported symptoms of depression 8.00(4.00,13.75),anxiety(23.43±7.80),anger(13.40±5.46),fear(72.81±27.26),somatic fear 9.00(6.00,12.75),loneliness(39.35±12.00),and low perceived emotional support(32.14±8.06).Parents who were young,single,low-income,and with limited-post secondary education reported greater loneliness and lower perceived emotional support.Fear correlated with depression(r=0.737,P<0.01)and anxiety(r=0.900,P<0.01).Inverse relationships were discovered between perceived emotional support and loneliness(r=-0.767,P<0.01),anger(r=-0.401,P<0.01),and depression(r=-0.334,P<0.01).Conclusions:The cluster of negative emotions identified will serve as potential targets for future interventions designed to enhance support for parents of critically ill children.

The Effects of Fetal Movement Counting on Mental Health of Mother in Third Trimester A Randomized Controlled Trial

Anxiety is one of the psychological problems in pregnant women that sometimes takes the form of pathological and affects the mental health of mother. The aim of this study was to determine the effects of fetal movement counting on mental health of mother. In a randomized-controlled trial, 208 nulliparous women were randomly divided into two groups. At 28th weeks, both groups completed the GHQ-28. Then the intervention group started to count fetal movements from 28th to 37th weeks of gestation and the control group received routine prenatal care. Again, both groups completed the questionnaire at 37 weeks＇ gestation and the results were compared. Analysis was performed by SPSS and a P value 〈 0.05 was considered significant. The mean scores of mental health of mothers in 28th and 37th of pregnancy was respectively 23.52 ± 10.23 and 21.09 ± 10.12 in the intervention group and the difference was significant （P = 0.025）. The mean in the control group was 23.69 ± 9.43 and 23.88± 8.60 respectively, and the difference was not significant （P = 0.52）. In comparing the mean scores between the two groups, it was found that the difference was not significant at 28th weeks of gestation （P = 0.37）, but it was significant in 37th week （P = 0.002） and the counting of fetal movements could improve the mental health of mothers compared to control group. The women who had fetal movements counting at weeks 28 to 37 Of gestation reported better mental health than the control group. The mother renorted concerns about decreased fetal movement was similar in the two grouns.

Microbiological Quality of Dates in the North Center Region of Morocco

Date palm （Phoenix dactylifera L.） fruit is an important component in arid and semi-arid diet regions of the world. The present study pointed out microbial investigating of date palm collected from National wholesale market in Fez city in the center north of Morocco. The results reveal that samples dates studied are contaminated by bacteria such as TAMF （total aerobic mesophilic flora）, ASR （anaerobic sulfite reducing）, yeasts and molds. The percentage of yeasts isolated is 50% for Saccharomyces cervisae, 10% for Zygosaccharomyces fermentati, 20% for Hansenula anomala, 10% for Lodderomyces elongisporus and 10% for Kluyveromyces fragilis. The frequency of molds distribution is 51% for Aspergillus niger, 33% for Penicillium notatum and 16% for Rhizopus oryzae. Newman and keuls grouping test shows that fungal germs distribution is equal for yeast and molds in all samples analyzed. In the opposite bacterial grouping test shows greet difference between groups of bacteria isolated from date＇s samples.

Relapse of a cardiac tumor from myxoma to low-grade malignant myofibroblastic sarcoma: malignant transformation or metachronous lesion?

A 47-year-old woman, who had undergone cardiac myxoma removal surgery six years ago, was readmitted due to a 2-week history of chest distress, and dyspnea with the change of body position. Both the examinations and the surgery confirmed a cardiac tumor relapse. Histology demonstrated that the mass resected in surgery had a pathologic change from myxoma to a low-grade malignant myofibroblastic sarcoma. The patient received heart transplantation 2 years later due to tumor recurrence, and finally died of cerebral hemorrhage.

Multilingualism and the Choice of a Language for Anglophone Education in Cameroon

This paper seeks to do three things： （1） examine the linguistic situation of Cameroon; （2） identify the language（s） used in education; and （3） discuss whether in the light of the social linguistic evidence, the current choice of language for education （English） is well motivated. The methodology employed is a socio-lin some randomly selected urban centers in Cameroon for example, Buea, Bamenda, Kumba, guistic survey of etc.. The results suggest among other things： （1） that Cameroon is a highly multilingual country with over 280 home languages and （2） that while English is the language for Anglophone education, Pidgin English is actually the predominant language and the first language for most Anglophones. Based on these findings, the author proposes Pidgin English as the choice language for early education in Anglophone Cameroon （the southwest and northwest regions）. Pidgin English is the only language which expresses Cameroonian reality. It is spoken by more than 70% of the population. It is the only language that is not associated with a particular tribe, religion, or with a specific colonial government.

Study on Brewing Technology of Apple Brandy

[Objective] The aim was to study the brewing technology of apple brandy. [Method] After the activated wine yeast was added to the apple juice by sizing classification, rinsing, falling to pieces and squeezing, the preceding fermentation began. Every other day, parameters of fer- mentation broth such as temperature, pH, acidity, sugar content and bubble nurdbers were detected. Once the sugar content of the fermentation suspension was approaching 5 -6 °Bx, the following fermentation would start via pouring wine. After 20 -30 days, the cider was changed into origi- nal apple brandy by distillation. The last procedure was aging which included man-made speediness aging and oak wood aging about 20 days. The physical and chemical compositions before and after aging were measured. [ Result] 22.5 kg apple resulted into 16.56 L of juice. The juice yield was about 73.6% （10 ml/kg）. The alcohol rate of distilled apple juice was 20.0%. The color of apple brandy was darker than that of original apple brandy. Alcohol level reduced, but total acidity, fixed acid, lipid and furfural content rose. [ Conclusion] The apple brandy was of particular flavor and high quality by selecting befitting fruit, activated wine yeast and feasible brewing, distillation and aging technology. It will be conductive to the development of apple processing industry and the research and development of key brandy technique.

Optimization of Culture Components for Laccase Activity from Pleurotus Ostreatus P40 Using Response Surface Methodology

High enzymatic activity is required for laccase applications.Central composite design （CCD）-based response surface methodology （RSM） can effectively increase the enzymatic activity of Pleurotus ostreatus P40 in liquid substrate fermentation.Initial screening of the nutritional components was performed using a Plackett-Burman design.The variables,namely,bran,bagasse,Tween 80,and yeast extract,were found to have statistically significant effects on laccase activity.These variables were further optimized using CCD-based RSM.Optimal concentrations for the maximum laccase activity were 8.144 2 g/L bran,50 g/L bagasse,0.424 1 mL/L Tween 80,and 2.832 5 g/L yeast extract.Under optimized conditions,the maximum measured laccase activity reached 96 480 U/L,which was close to the predicted value （104 830 U/L） by RSM.Therefore,RSM can be used to optimize culture components for laccase activity from Pieurotus ostreatus P40.

Effect of Drought Stress on Yield Performance of Parental Chickpea Genotypes in Semi-arid Tropics

Chickpea （Cicer arietinum L.） is an important cool season food legumes with indeterminate growth habit. The crop is valued for its nutritive seeds and used as animal feed in many developing countries. The productivity of the crop is constrained by several abiotic stresses, among which drought stress is one of the key determinants of crop performance aaccounting for 40-50% yield reduction globally. The present study was conducted to screen, evaluate and select chickpea genotypes possessing high yield potential under drought stress condition at ASALs （arid and semi-arid lands） of Kenya. The experiment was conducted at Chemeron dry land and Eco-tourism Research station, Egerton University and Kenya Agricultural and Livestock Research Institute （KALRO）, Pekerra, Marigat, Baringo County. The genotypes were planted in RCBD （randomized complete block design） in three replicates at a spacing of 30 cm × 10 cm, giving a plant density of approximately 25 plants/m2. Combined analysis of variance revealed existence of highly significant differences among the tested genotypes for most of the agronomic traits. Overall, the highest grain yield was obtained from ICCV 92944 （1,173 kg/ha）, ICCV 92318 （1,103 kg/ha） and CAVIR （975 kg/ha）, ICCV 92318 （967 kg/ha）, ICCV 00108 （956 kg/ha） and ICC 4958 （921 kg/ha）： possibly due to its comparatively higher drought （and heat） tolerance, and hence could be used as sources of drought tolerance in further breeding programs. This study was carried out in few drought tolerant sites and further more sites need to be evaluated in addition to other drought and heat screening and optimization of protocols, facilities and analytical approaches to identify better genotypes that respond appropriately to climate change.

Update on Anti-Saccharomyces cerevisiae antibodies, anti-nuclear associated anti-neutrophil antibodies and antibodies to exocrine pancreas detected by indirect immunofluorescence as biomarkers in chronic inflammatory bowel diseases: Results of a multicent

AIM： Anti-Saccharomyces anti-nuclear associated cerevisiae antibodies （ASCA）, anti-neutrophil antibodies （NANA） and antibodies to exocrine pancreas （PAB）, are serological tools for discriminating Crohn＇s disease （CrD） and ulcerative colitis （UC）. Like CrD, coeliac disease （COD） is an inflammatory bowel disease （IBD） associated with （auto） antibodies. Performing a multicenter study we primarily aimed to determine the performance of ASCA, NANA and PAB tests for IBD diagnosis in children and adults, and secondarily to evaluate the prevalence of these markers in CoD. METHODS： Sera of 109 patients with CrD, 78 with UC, 45 with CoD and 50 healthy blood donors were retrospectively included. ASCA, NANA and PAB were detected by indirect immunofluorescence （IIF）. RESULTS： ASCA＋/NANA- profile displayed a positive predictive value of 94.2% for CrD. Detection of ASCA was correlated with a more severe clinical profile of CrD and treatment of the disease did not influence their serum levels. ASCA positivity was found in 37.9% of active CoD.PAB were found in 36.7% CrD and 13.3% CoD patients and were not correlated with clinical features of CrD, except with an early onset of the disease. Fifteen CrD patients were ASCA negative and PAB positive. CONCLUSION： ASCA and PAB detected by IIF are specific markers for CrD although their presence does not rule out a possible active CoD. The combination of ASCA, NANA and PAB tests improves the sensitivity of immunological markers for CrD. Repeating ASCA, NANA, and PAB testing during the course of CrD has no clinical value.

汉语“死”以及以母读音问题

以母读音问题可以说是上古汉语语音研究领域里面最为复杂的难题。自高本汉构拟为^＊d-以来，以母的构拟一直处于不断的变动之中，如同以母的谐声一样“五花八门”。近些年来，学界有一种普遍的趋势是认为以母为边音^＊l-。以母跟心母有语音上的联系，而语词“死”就是其中之一。语词“死”的词根辅音也相应地被构拟为清边音^＊lh-。以语词“死”以及相关语词作为考察的基点，我们发现跟以母有语音关联的心母上古跟中古一样只是一个清擦音^＊s-，而以母则是一个浊擦音^＊z-。以母构成的谐声系列中古复杂多样，是由于擦音^＊s-／^＊z-在不同的条件下演变成的。其中最为重要的是擦音的塞化，而擦音塞化是整个汉藏语系重要的音变现象之一。

Should few retrieved oocytes be as an indication for intracytoplasmic sperm injection?

Objective:To reevaluate whether relatively few oocytes obtained in one cycle are an indication for intracytoplasmic sperm injection(ICSI).Methods:A total of 406 cycles with three or fewer retrieved oocytes performed in 396 non-male infertile couples were retrospectively reviewed.Cycles were classified into three groups by different fertilization techniques:the in vitro fertilization(IVF) group,insemination with conventional IVF;the ICSI group,insemination with ICSI though semen parameters were normal;and the rescue ICSI group,re-insemination with ICSI after conventional IVF failure.Results:The ICSI group resulted in higher normal fertilization compared with the conventional IVF group.Correspondingly,the cycle cancellation rate was decreased in the ICSI group,though it was not statistically significant.The clinical pregnancy rate and implantation rate were lower in the ICSI group compared with the conventional IVF group.Rescue ICSI was a method to avert total fertilization failure in conventional IVF,increasing fertilization and ensuring embryo availability for transfer,but the normal fertilization was the lowest due to delayed insemination and the chance of pregnancy was very little.Conclusions:Obtaining only few oocytes in one cycle is not considered as an indication for ICSI when the sperm sample is apparently normal.Rescue ICSI is either not recommended if conventional insemination fails.Such patients should not be subjected to the unnecessary costs and potential risks of ICSI.

Psychosocial impact of mothers with perinatal loss and its contributing factors:an insight

Objective:To evaluate the psychosocial impact among mothers with perinatal loss and its contributing factors.Methods:A cross sectional study was conducted in University Kebangsaan Malaysia Medical Centre (UKMMC) from April 2008 to May 2009 using Edinburgh Postnatal Depression Scale (EPDS) and self administered questionnaire.Results:Sixty-two respondents were included and most of them were working mothers (77.4%).The mean age of the respondents was (31.0±5.6) years and a majority of the subjects aged between 20-34 years (77.4%).According to the EPDS score,53.2% of the respondents had a psychosocial impact with a total score of >9,out of 30.There was a significant relationship between psychosocial impact after perinatal loss and support from friends (P=0.019).However,there were no significant differences between psychosocial impact and history of previous perinatal loss,ethnicity,occupation,educational level,age or total income.Conclusion:Mothers with perinatal loss should be screened for psychosocial impact and offered support when needed.Family and friends should continue to provide emotional support.People who have experienced similar problem before will be able to provide better support than those who have not.
