Rhesus monkeys (Macaca mulatta) are human's closest evolutionary relatives next to Chimpanzees, and they are widely used in biomedical researches. Analyses of the rhesus monkey trasnscriptome and the sequence divergence between monkey and human are of importantce to the development of scientific analyses and to the application and interpretation of the results from animal experiments. In this study, we analyzed the genetic and transcriptional information. Four hundred and one clones were randomly selected from a liver tissue cDNA library of rhesus monkey, and the expressed sequence tags (ESTs) were sequenced. We acquired 393 effective ESTs that were assembled into 221 Unigenes with Phrap software. Alignments of the sequences showed that 188 Unigenes matched with known proteins in Swiss_prot database, of which 16 Unigenes matched the known rhesus proteins, and 171 Unigenes had high homology with human proteins. Then the result of BLASTN comparison showed that 26 of another 33 Unigenes matched the known rhesus genes. Finally, the remaining Unigenes were aligned in dbEST and rhesus genome database, and the results suggested 3 Unigenes be newly discovered ESTs of rhesus.

Objectives To investigate the efficiency and safety of ultrasound-guided microwave ablation (MWA) for hepatocellular carcinoma (HCC) adjacent to danger areas.Methods The 106 patients with HCC treated by ultrasound-guided MWA were retrospectively included in our study.There were 149 lesions in total,including 8 lesions adjacent to gallbladder,33 lesions adjacent to grade Ⅰ-Ⅱ bile duct,39 lesions adjacent to diaphragm,28 lesions adjacent to gastrointestinal tract and 41 lesions adjacent to hepatic capsule.The mean diameter of the tumors was (2.04 ±0.92)cm.Individualized treament strategies for different sites of the tumors were conducted.The early complete ablation rate of the tumors was assessed by enhanced computed tomography (CT) or magnetic resonance imaging (MRI) one month later and followed up regularly.Results The total inactivation rate was 89.9%.The early complete ablation rates of adjacent gallbladder,adjacent grade Ⅰ-Ⅱ bile duct,adjacent diaphragm,adjacent gastrointestinal tract and adjacent hepatic capsule were 100%,84.8%,89.7%,92.9%,90.2% respectively.The local progression rates were 0,15.2%,10.3%,7.1%,9.8%,respectively.The 1-,2-and 3-year survival rates were 91.6%,85.8% and 74.5%.Total cases were ablated 149 times.Serious complications accounted for 6.6%,including diaphragm injury,needle implantation,abdominal hemorrhage,severe infection,bile tumors.Conclusions Our study presented a novel individualized treament strategies using MWA in HCC patients.The individualized scheme effectively boosted the complete ablation rate of tumors and significantly improve the clinical outcome of HCC patients.

Objective :
To evaluate the immune effects of inactivated H7N9 influenza vaccine.
Methods :
We searched several common databases(The Cochrane Library,PubMed,China Biology Medicine disc,China National Knowledge Infrastructure,etc.)for research articles about immune effects of H7N9 influenza vaccine published from the time the database built to July 10th of 2018,using H7N9 and vaccine as keywords. After screening the articles according to the inclusion and exclusion criteria,we assessed the quality of the studies and then employed seroconversion rate(SCR)as an outcome indicator to analyze the immune effects of different doses and adjuvants.
Results :
We recruited 5 articles on inactivated H7N9 influenza vaccine from 1 679 articles. The sample size was 2 579. The results of the meta-analysis showed that the rate difference(RD)values of SCR in each dose group after the first dose ranged from 1% to 10%,which indicated a poor protective effect;after the second dose of immunization,the RD values of SCR in the vaccines without adjuvants ranged from 13% to 19%,which was not effective enough;the RD values of SCR in the vaccines with adjuvants ranged from 62% to 69%,which met the licensing criteria for influenza vaccine;better results could be achieved when immunized with two doses of vaccines with adjuvants( RR=1.19,95%CI:1.02-1.39);vaccines with AS03 or MF59 at the lowest dose of 3.75 μg had the same immune effects as ones at a dose of 15 μg;vaccines with AS03(RD=89%,95%CI:85%-93%)were superior to those with MF59(RD=42%,95%CI:9%- 75%).
Conclusion
Inactivated H7N9 influenza vaccines could achieve good immune effects when inoculated two doses with adjuvants,and the minimum effective dose was 3.75 μg.

Objective To analyze the current status and trends of chronic kidney disease (CKD) burden in China from the global perspective, and to provide reference for the prevention and control of CKD in China. Methods The incidence, prevalence, mortality and disability adjusted life year (DALY) rate of China and other regions were retrieved from GBD 2019. Comparative analyses were carried out to reflect the burden of CKD. Results In 2019, the incidence and the prevalence in females were higher than those in males, while the mortality and the DALY rates in females were lower than those in males. There were obvious distinctions in different age groups and people over 65 years old had a higher CKD burden. The burden of CKD mainly came from hypertensive nephropathy and type 2 diabetic nephropathy. From 1990 to 2019, the DALY rate of CKD in China showed an overall upward trend. After eliminating the differences in age composition, the standardized DALY rate of CKD in China was higher than that in Japan, Korea and Ukraine although lower than the global. The main influencing factors of the burden of CKD were metabolic factors. Conclusion The burden of CKD in China is continuously rising. It is still necessary to pay attention to the three-level prevention and control, and focus on the key people groups and high-risk factors to further reduce the burden of CKD in China.
