Objective: In dryland areas of China, alfalfa hay (AH) is a possible substitute for concentrate feed for beef cattle. To evaluate the potential benefits of this substitution, we studied the effect of the ratio of AH intake to total dry matter (DM) intake on average daily body-weight gain (ADG), dietary energy utilization status, and economic benefit in Gansu province. Methods: In each of two feeding trials in 2016 (trial 1 [T1], July 3 to 17; trial 2 [T2], August 15 to September 23), crossbred male Simmental calves were allocated to low AH (LA), medium AH (MA), and high AH (HA) feeding groups (n = 4 per group). The target ADG was set as 1 kg for both trials. In a one-way-layout design based on conventional feeding practices in the province, calves received diets containing the different AH amounts, with a constant ratio of corn stover:total DM and decreasing rations of concentrate feed proportional to the increase in AH. Calves in T1 received AH at 15% (T1-LA), 23% (T1-MA), or 31% (T1-HA) of their dietary DM allowances; those in T2 received 9% (T2-LA), 24% (T2-MA), or 34% (T2-HA) AH. Results: Among the T1 groups, both ADG and economic benefit were highest in T1-LA; whereas in T2, they were higher in the T2-LA and T2-MA groups than in T2-HA. Energy digestibility did not significantly differ among the groups in either trial. The dietary AH inclusion ratios of 14% in the warm season and 8% to 21% in the cool season appeared to yield optimal ADG, metabolizable energy intake, and economic benefit. Conclusion: Low-level inclusion of AH, ranging from 8% to 21%, is a practical approach for beef cattle feeding. This modified feeding regimen likely will promote increased growth performance during the fattening stage of beef steers in dryland areas of Gansu province, China.

It is generally called that the Dunhuang Manuscript ${\ulcorner}Shanghanlun{\lrcorner}$ (敦煌本 ${\ulcorner}$傷寒論${\lrcorner}$ ) is all the series of documents relating to the Shanghanlun (傷寒論) included in one of the testaments, which was, in 1900, originally found in the Cangjing hole(藏經洞, Mogao cave(莫高窟), Dunhuang(敦煌), Gansu province(甘肅省). I tried to research on the ${\ulcorner}Fuhengjue$ Zangfuyongyao $Fayao{\lrcorner}$ (${\ulcorner}$輔行訣藏府用樂法要${\lrcorner$) in the Dunhuang Testament (敦煌遺書), which include main texts of the ${\ulcorner}Tangyejingfa{\lrcorner$ (湯液經法) upon which the ${\ulcorner}Shanghanlun{\lrcorner}$ (傷寒論) is based, because it seems to be in the category of the Dunhuang Manuscript ${\ulcorner}Shanghanlun{\lrcorner}$ (敦煌本 ${\ulcorner}$傷寒論${\lrcorner}$) in the broadly extended sense.

To analyze the seismic reliability of concrete rectangular liquid storage structures (CRLSSs), assuming that the wall thickness and internal liquid depth of CRLSSs are random variables, calculation models of CRLSSs are established by using the Monte Carlo finite element method (FEM). The principal stresses of the over-ground and buried CRLSSs are calculated under three rare fortification intensities, and the failure probabilities of CRLSSs are obtained. The results show that the seismic reliability increases with the increase of wall thickness, whereas it decreases with the increase of liquid depth. Between the two random factors, the seismic reliability of CRLSSs is more sensitive to the change in wall thickness. Compared with the over-ground CRLSS, the buried CRLSS has better reliability.

본 연구는 중국의 WTO가입 이후 중국 각 성 시(省 市)가 조직을 잘 운영하고 있는지 가늠해보고, 이를 근거로 향후 어느 정도 개선이 필요한지를 판단하기 위해서 2002년부터 2006년까지의 중국 각 성 시의 데이터를 이용하여 자료포락분석(DEA)기법 중 투입지향CCR모형과 투입지향BCC모형으로 효율성평가를 실시하였다. 투입지향모형을 활용하는 것은 산출보다는 투입부문에서의 절감 등이 더 용이하다고 판단한 것에 기인하며, 일반적으로 지방정부 효율성평가에서 활용되고 있다. 분석결과 상해만이 2002년부터 2006년까지 꾸준히 효율성이 가장 높은 성(省)으로 나타났는데, 다른 성 시들은 발전과 효율성제고를 위해 상해를 벤치마킹할 필요가 있다고 본다. 지리적 문화적 정서적 차이 등이 있겠지만 서장, 산서, 감숙, 청해, 영하 그리고 신강은 WTO가입 이후에도 지속적으로 효율성이 낮은 지역으로 분류되는데, 다양한 소수민족으로 구성되어 있고 지역 간 경제발전의 편차가 심한 중국의 입장에서는 정책수립 시 이들 지역에 대한 경제발전방안 등을 마련하는데 기초 자료로서 자료포락분석(DEA)기법에 의한 효율성평가결과를 활용하는 것이 바람직할 수도 있다.

Objectives: To assess knowledge of HPV and attitudes towards HPV vaccination among the general female population, government officials, and healthcare providers in China to assist the development of an effective national HPV vaccination program. Methods: A cross-sectional epidemiologic survey was conducted across 21 urban and rural sites in China using a short questionnaire. 763 government officials, 760 healthcare providers, and 11,681 women aged 15-59 years were included in the final analysis. Data were analyzed using standard descriptive statistics and logistic regression. Results: Knowledge of HPV among the general female population was low; only 24% had heard of HPV. Less than 20% of healthcare providers recognized sexually na$\ddot{i}$ve women as the most appropriate population for HPV vaccination. There was high acceptance of the HPV vaccine for all categories of respondents. Only 6% of women were willing to pay more than US $300 for the vaccine. Conclusions: Aggressive education is necessary to increase knowledge of HPV and its vaccine. Further proof of vaccine safety and efficacy and government subsidies combined with increased awareness could facilitate development and implementation of HPV vaccination in China.

The 2 species of the genus Anoplocephala (Anoplocephalidae), A. perfoliata and A. magna, are among the most important equine cestode parasites. However, there is little information about their differences at the molecular level. The present study revealed that the mitochondrial (mt) genome of A. magna was 13,759 bp in size and 700 bp shorter than that of A. perfoliata. The 2 species includes 2 rRNA, 22 tRNA, and 12 protein-coding genes each. The size of each of the 36 genes was the same as that of A. perfoliata, except for cox1, rrnL, trnC, trnS2(UCN), trnG, trnH, trnQ, and trnP. In the full mitochondrial genome, the sequence similarity was 87.1%. The divergence in the nucleotide and amino acid sequences of individual protein-coding genes ranged from 11.1% to 16% and 6.8% to 16.4%, respectively. The 2 non-coding regions of the mt genome of A. magna were 199 bp and 271 bp in length, while the equivalent regions in A. perfoliata were 875 bp and 276 bp, respectively. The results of this study support the proposal that A. magna and A. perfoliata are separate species, consistent with previous morphological analyses.

A loop-mediated isothermal amplification (LAMP) assay allows rapid diagnosis of Toxoplasma gondii infection. In the present study, the LAMP assay was evaluated using blood from both naturally and experimentally infected pigs. The sensitivity of the LAMP assay was compared with that of Q-PCR. Both assays detected T. gondii in the blood of experimentally infected pigs, with 100% agreement. In infected blood samples, the parasite was detected as early as 2 days post-infection and reached a peak in 3-5 days. In 216 field serum samples, the detection rates of LAMP and Q-PCR assays were 6.9% and 7.8%, respectively. This result indicates that the sensitivity of the LAMP assay was slightly lower than that of the Q-PCR assay. However, the LAMP may be an attractive diagnostic method in conditions where sophisticated and expensive equipment is unavailable. This assay could be a powerful supplement to current diagnostic methods.

The Silk Road, a trans-Eurasian network of trade routes connecting East and Southeast Asia to Central Asia, India, Southwest Asia, the Mediterranean, and northern Europe, which flourished from roughly 100 BCE to around 1450, has enjoyed two modern eras of intense academic study. The first spanned a period of little more than five decades, from the late nineteenth century into the early1930s, when a succession of European, Japanese, and American scholar-adventurers, working primarily in Chinese Turkestan (present-day Xinjiang Uyghur Autonomous Region, which comprises China's vast northwest) and China's Gansu Province (to the immediate east of Xinjiang) rediscovered and often looted many of the ancient sites and artifacts of the Silk Road. The second era began to pick up momentum in the 1980s due to a number of geopolitical, cultural, and technological realities as well as the emergence of the New World History as a historiographical field and area of teaching. This second period of fascination with the Silk Road has resulted in not only a substantial body of both learned and popular publications as well as productions in other media but also in an ever-expanding sense among historians of the scope, reach, and significance of the Silk Road.

Objective: Spermatozoa are produced within the seminiferous tubules after sexual maturity. The expression levels of mRNAs and lncRNAs in testicular tissues are different at each stage of testicular development and are closely related to formation of the extracellular matrix (ECM) and spermatogenesis. Therefore, we set out to study the expression of lncRNAs and mRNAs during the different developmental stages of the goat testis. Methods: We constructed 12 RNA libraries using testicular tissues from goats aged 3, 6, and 12 months, and studied the functions of mRNAs and lncRNAs using the gene ontogeny (GO) and Kyoto encyclopedia of genes and genomes (KEGG) databases. Relationships between differentially expressed genes (DEGs) were analyzed by lncRNA-mRNA co-expression network and protein-protein interaction network (PPI). Finally, the protein expression levels of matrix metalloproteinase 2 (MMP2), insulin-like growth factor 2 (IGF2), and insulin-like growth factor-binding protein 6 (IGFBP6) were detected by western blotting. Results: We found 23, 8, and 135 differentially expressed lncRNAs and 161, 12, and 665 differentially expressed mRNAs that were identified between 3 vs 6, 6 vs 12, and 3 vs 12 months, respectively. GO, KEGG, and PPI analyses showed that the differential genes were mainly related to the ECM. Moreover, MMP2 was a hub gene and co-expressed with the lncRNA TCONS-0002139 and TCONS-00093342. The results of quantitative reverse-transcription polymerase chain reaction verification were consistent with those of RNA-seq sequencing. The expression trends of MMP2, IGF2, and IGFBP6 protein were the same as that of mRNA, which all decreased with age. IGF2 and MMP2 were significantly different in the 3 vs 6-month-old group (p<0.05). Conclusion: These results improve our understanding of the molecular mechanisms involved in sexual maturation of the goat testis.

A Scanning Rayleigh Doppler lidar for wind profiling based on a non-polarized beam splitter cube optically contacted FPI is developed for wind measurement from high troposphere to low stratosphere in 5-35 km. Non-polarized beam splitter cube optically contacted to the FPI are used for a stable optical receiver. Zero Doppler shift correction is used to correct for laser or FPI frequency jitter and drift and the timing sequence is designed. Stability of the receiver for Doppler shift discrimination is validated by measuring the transmissions of FPI in different days and analyzed the response functions. The maximal relative wind deviation due to the stability of the optical receiver is about 4.1% and the standard deviation of wind velocity is 1.6% due to the stability. Wind measurement comparison experiments were carried out in Jiuquan ($39.741^{\circ}N$, $98.495^{\circ}E$), Gansu province of China in 2015, showing good agreement with radiosonde result data. Continuous wind field observation was performed from October 16th to November 12th and semi-continuous wind field of 19 nights are presented.
