Objective To explore the effect of Genistein on the proliferation and cell cycle regulation of ovarian cancer cells. Methods Ovarian cancer OVCAR-5 cells were treated with Genistein . Cell counting and MTS assays were performed to determine the alterations of cell proliferation. Real-time PCR and Western blotting were conducted to examine the expression changes of key cell cycle regulators. Results Genistein significantly promoted the proliferation and viability of OVCAR-5 cells. After Genistein treatment. cellular mRNA and protein expression levels of cell cycle activators such as PCNA. Cyclin Dl and CDK4 were increased. but those of cell cycle inhibitors such as p21 and p27 were decreased. Conclusion Genistein can upregulate the proliferation and Gl-S transition of ovarian cancer OVCAR-5 cells. The discrepancy may be caused by diverged experimental conditions and/ or different ER expression patterns of cell lines. The findings may provide basic information for in-depth analysis of the role (s) and mechanisms by which genistein confers its effect on ovarian cancer cells. [ABSTRACT FROM AUTHOR]

Objective To evaluate intra-fractional prostate motion by applying four-dimensional real-time transperineal ultrasound (TPUS) so as to provide reference evidence for the moderate hypofrectionation radiotherapy for prostate cancer. Methods Ten patients with prostate cancer were randomly selected to be treated with volume modulated radiotherapy (VMAT). TPUS was utilized to collect 60 intra-fraction data. Prior to each treatment for all the patients, CBCT was adopted to correct inter-fraction setup errors. During treatment, fourdimensional real-time ultrasound images were acquired to monitor the 3D prostate motion. Results Among all the data, the maximum distance of prostate motion was 1.85mm in the left direction, 0.50mm in the right direction, 1.83mm in the anterior direction, 3.04mm in the posterior direction, 2.68mm in the cranial direction, and 1.75mm in the caudal direction. The percentage of fractions in which the distance of prostate motion was more than 2mm among all treatment fractions was 3% in the left and right (LR) direction, 11% in the anterior and posterior (AP) direction, and 5% in the cranial and caudal (CC) direction. The distance was greater in AP direction than in AP direction and CC direction. Conclusion TUPS is a non-invasive and reliable technique which can detect the real-time motion of the prostate during radiotherapy aiming to prevent tumor target areas from being missed or normal tissues from being overexposed.

【Objective】In order to provide theoretical reference for the selection of sugarcane varieties suitable for mechanized harvesting,the effect of mechanical harvesting on harvest quality and growth of different varieties of ratoon sugarcane was studied.【Method】The experiment was conducted by random block design. 11 varieties of two-year ratoon sugarcane were harvested mechanically and artificially treatment. Two treatments were set up in mechanical harvest. One was rolling over the plant ridge,and the other one was not. Harvest quality and agronomic characters were investigated after harvest.【Result】The average impurity rate of tested varieties by mechanical harvest was 10.93 %. The impurity content of ratoon sugarcane of mechanical harvest treatment was higher than that of CK(except Guitang 34),impurity rate of Guitang 02-1247 and Yunzhe 03-332 were high and were significantly higher than CK(P<0.05,the same as below),while that of artificial harvest treatment was cleaner. The stubble height and broken rate of mechanical harvest treatment were 4.25 cm and 14.28 %(absolute value) lower than that of artificial harvest treatment,respectively. Stubble height of Guiyin C1-2003 was low and very significantly lower than that of artificial harvest(P<0.01),its broken rate was high but still significantly lower than that of artificial harvest. Stubble height of Yunzhe 03-332 was high,broken rate was the highest,and the difference between harvest methods was not significant(P>0.05). The soil bulk density of mechanical harvest rolling treatment was 1.54 g/cm~3,which was 35.09 % and 23.20 % higher than that of before harvest and non-rolling treatment; and the soil water content of furrow after mechanical harvest was 23.44 %,16.15 % higher than that before harvest. Compared with the artificial harvest,the stubble seedling rate(165.31 %),plant height(27.73 cm) and pseudo-stem diameter(13.13 mm) of different varieties of ratoon sugarcane of mechanical harvest and rolling treatment decreased by 46.16 %,28.90 % and 17.99 %,respectively.Stubble seedling number of Guiyin C1-2003 was large,but stubble seedling rate was low,stubble seedling number of yunzhe 03-332 was the smallest and stubble seedling rate was low. Plant height of Guiyin C1-2003 by mechanical harvest was high,pseudo-stem diameter was thick,but plant height of yunzhe 03-332 was low,pseudo-stem diameter was thin.【Conclusion】Compared with the artificial harvest,the mechanical harvest has higher impurity rate,but lower stubble height and broken rate. The adverse effects of mechanical harvest on the growth of ratoon sugarcane are mainly caused by the rolling over the plant ridge,and are different due to the ratooning ability of different varieties. Considering the rooting quality and mechanical harvest quality,Guiyin C1-2003 is suitable for mechanical harvesting,Yunzhe 03-332 is not suitable for mechanical harvesting. [ABSTRACT FROM AUTHOR]

Objective The aim of this study was to investigate the effect of Charlson complication index (CCI) score on the mortality of patients with fragile hip fractures. Methods The data of elderly patients with fragile hip fractures treated in our hospital from January 2010 to December 2015 were retrospectively analyzed. The CCI score was retrospectively analyzed from the medical records. The total CCI score (complication score + age score) and complication score of each patient were calculated respectively. The relationship between CCI score and 1-year mortality and follow-up mortality was analyzed. Results From January 2010 to December 2015, there were 690 over 50-year-old elderly patients with fragile hip fractures received effective follow-up in our hospital. The average age of the patients was 77.19 ± 10.38 years old. The patients were followed up for 7 to 52 months, with an average follow-up of 28.53 ± 9.75 months. Among these patients, 99 died in one year, with a mortality rate of 15.60% (99/635), and 166 died during the follow-up period, with a total mortality rate of 24.06% (166/690). According to the CCI total score, the patients were divided into two groups (5 score and ≥5 score). The one-year mortality rate and the total mortality during follow-up period were lower in the group of less than 5 score. There was significant statistical difference between the two groups (P<0.05). According to CCI complication score, the patients were divided into two groups (<1 score and ≥1 score). The one-year mortality rate and the total mortality during follow-up period were lower in the group of less than 1 score. There was significant statistical difference between the two groups (P<0.05). Conclusion Different CCI scores have certain effect on the one-year mortality and the total mortality during follow-up period of fragile hip fractures in the elderly. CCI score provides good preoperative indicators for elderly patients with fragile hip fracture, which helps to predict the outcome of treatment and to guide our treatment. [ABSTRACT FROM AUTHOR]

Osteoporosis (OP) is a systemic metabolic bone disease with decreased bone mass, destructive micro-structure，and increase of the fracture risk. Osteoporotic fracture is a common complication of osteoporosis, which happens mostly in the elderly, but it may also occur in other age groups. The most common sites of fragility fractures occur in the hip, spine, and wrist joints. There are a variety of available and effective treatment methods for osteoporosis, such as bisphosphonates and calcitonin. However, due to factors such as insufficient knowledge of osteoporosis among doctors and patients, patients’ excessive concerns about side effects of drugs, and high prices of anti-osteoporosis drugs, osteoporosis patients still have lower drug treatment rates and compliance. This leads to a slower increase in bone mineral density and an increase in the incidence of fractures, greatly increasing the clinical and economic burden. Hence, early anti-osteoporosis treatment and long-term adherence to medication can alleviate bone loss and even increase bone mass, which significantly reduces the risk of fracture. This article mainly reviews the current situation of osteoporosis drug treatment rate and compliance, the causes of drug treatment rates and compliance, and puts forward measure to improve the treatment rate and compliance of anti-osteoporosis drugs.

Objective To investigate the correlation between serum hydroxyl vitamin D level and fragile hip fractures. Methods The clinical data of 181 female fragile hip fracture patients (age ≥50 years), who were admitted to our hospital from January 2013 to December 2015 and undergone serum 25-hydroxyl vitamin D (25OHD) test, were analyzed retrospectively. The age, fracture site, serum 25OHD level and bone mineral density (BMD) of the patients, as well as the outcome of 67 patients followed up for at least one year, were recorded. The correlation between serum 25OHD level and these indices was observed. Results In 181 over 50 years old female patients with fragile hip fractures, there were 127 cases (70.2%) with vitamin D deficiency, 42 cases (23.2%) with vitamin D insufficiency, and 12 cases (6.6%) sufficient vitamin D. The serum 25OHD level in patients who were less than 75 years was markedly higher than that in patients over 75 years old. BMD level in patients with 25OHD over 20ng/mL was higher than in patients with 25OHD less than 20ng/mL. The serum 25OHD level in patients with femoral neck fractures was higher than in patients with inter-trochanter fractures, but the difference was not statistically significant. Among patients followed up within one year, the patients with 25OHD over 20ng/mL had lower fall rate, fracture rate, and all-cause mortality than those with 25OHD less than 20ng/mL, but the difference was not statistically significant. The outdoor action ability in patients with 25OHD over 20ng/mL was markedly higher than that in patients with 25OHD less than 20ng/mL. Conclusion Vitamin D deficiency and insufficiency are prevalent in elderly female patients with fragile hip fractures. Serum 25OHD level is correlated with age, BMD, and the outcome of the patients.

Objective To observe the effect of zoledronic acid(ZA) on electrocardiographic parameters in osteoporosis patients. Methods A prospective self-control study was conducted to observe 90 patients with primary osteoporosis before and after treatment. Patients aged 52-92 years, with an average age of 68.3±9.7 years(6 males and 84 females). Serum biochemical examination and routine electrocardiogram(ECG) were performed before using intravenous zoledronic acid and routine electrocardiogram was examined after using intravenous zoledronic acid(5 mg/100 mL). ECG parameters were compared before and after intravenous ZA, and meaningful changes in ECG reports were recorded. Results The atrial rate and ventricular rate increased significantly after ZA infusion(P<0.05). The QT interval was significantly shortened after ZA infusion(P<0.05). There were no statistical differences in the variation of P wave duration, PR interval, QRS wave duration, QRS axis, RV5+SV1 and QTc(P>0.05). There were 2 cases with benign changes from arrhythmia to non-arrhythmia(2.2%). The ECG reports showed 8 cases of adverse changes(8.8%), including 1 case of atrial fibrillation(1.1%). Conclusion The probability of serious arrhythmias such as atrial fibrillation in the treatment of osteoporosis with zoledronic acid is relatively small, and the overall safety of zoledronic acid in electrocardiogram is relatively high.

Objectives J Due to a genetic feature of the sterile 1 ine, there is a serious crack-glume in hybrid rice seeds. The crack-glume will cause the germination and seedling quality of rice seeds to be worse than normal seeds. Therefore, recognizing the crack-glume rice seeds and sorting them out can effectively improve the seedling quality of the seed and the yield of the field production. [Methods]In this study, a piezoelectric accelerometer was used to obtain the impact vibration signal generated by the rice seed falling and impacting the plate, which was made of 65Mn spring steels. The impact vibration signal was analyzed to recognise the normal and crack-glume of rice seeds. Orthogonal experiments were carried out to analyze the effects of metal plate thickness, length and seed falling height on the recognition rate of the crack-glume rice seed. [Results] The experimental results showed that the time-domain characteristic parameters of the impact vibration signal: voltage maximum, range, energy, root mean square, kurtosis, etc. could be used as the eigenvalues for distinguishing between normal and crack-glume rice seeds. Distinguishing effect by using energy was the best. The energy produced by the normal seed impacting the plate was generally greater than that of the crack-glume seed. When the plate thickness was 0.25 mm, the plate length was 200 mm, and the seed falling height was 250 mm, the comprehensive recognition rate was the largest. The comprehensive recognition rate of * Zhendao' Chuanyou 6203 * Quanyou 123 and ' Zhongyiyou 188' was 85.10%, 85.50%, 84.40% and 83.40%, respectively. [Conclusions] The method for recognising hybrid crack-glume rice seeds by the rice seed falling impact and impacting steel plate vibration is feasible. [ABSTRACT FROM AUTHOR]

[Objectives] Wheatear spikelet number and grain number directly reflect the yield of wheat,which are two very important parameters in the research of wheat phenotype. This measuring accuracy about the number of spikelet is very low at present,which can not meet the actual needs of breeding and estimating yield. The literature on measuring grain number has not yet appeared.[Methods] In order to measure these two parameters quickly,a parabolic segmentation method based on image processing technique for wheatear spikelet was presented in this paper,and the synchronously counting spikelet number and grain number were realized by using the wheatear front view image. Firstly,image preprocessing algorithm was used in order to obtain adjusted binary image of wheatear. Then the pixels were summed according to rows of binary image,and the curve of the row pixels sum was plotted. Then the smoothing curve was obtained by using smoothing filtering algorithm and the peaks and troughs of the smoothing curve were obtained by using extracting extremum. The stalk of the wheat was separated by setting a pixels threshold depending on the width difference between the stalk and the ear head. The number of peaks at the ear head in the smoothing curve indicated the number of spikelet. Then the abscissa values of the peaks and troughs were obtained,which represented the ordinal number Y of rows in binary image. A set of intersection points between the rows ordinal number Y and the boundary of the wheatear in binary image could be obtained. Then the midpoint coordinate of the wheatear boundary was obtained at the trough. And the maximum and minimum point coordinates of the wheatear boundary were obtained at the peak. Then three position points of fitting the parabolic curve for spikelet were ascertained according to the coordinate of peaks and troughs of the smoothing curve at the binary image. Finally,each spikelet in wheatear was segmented using the fitted parabolic curve. The area of each spikelet was extracted. Meanwhile,the grain number of each spikelet was counted manually. So then the relation between the area of each spikelet and the grain number was obtained by using threshold method.[Results]The wheatear images of three wheat varieties were identified to validate the spikelet number and grain number of each wheatear. The experiment results manifested that the average zero error rate of the spikelet number for three wheat varieties was 68.16%,the average absolute error of three wheat varieties of the spikelet number was 0.46,and the average relative error of the spikelet number for three wheat varieties was 2.99% by using aforementioned method to identify the spikelet number at wheatear. The recognition accuracy and the average zero error rate of the spikelet number were greatly improved by compared with the existing literature. And using aforementioned method to identify the grain number at wheatear,the average absolute error of grain number for three wheat varieties was 2.11,and the average relative error of grain number for three wheat varieties was 5.62%.The average measurable time for three wheat varieties was 7.99 s for a wheatear.[Conclusions] The automatically image counting wheat grain number and spikelet number for a wheatear with faster and higher precision can be realized.
