Targeted radiation therapy using radionuclides is a favored approach for treating tumors.This procedure involves the delivery of drugs to the lesion site via carriers or interventional methods,followed by the emission of radiation energy that selectively irradiates the lesion tissue.This approach minimizes damage to normal tissue and achieves the desired therapeutic effect.Factors such as the type of therapeutic radionuclide,radiation energy,physical half-life,method of preparation,and toxicity determine their clinical application.In this paper,the characteristics and clinical application of therapeutic radionuclides were reviewed to providing reference for the clinical application of targeted therapeutic radionuclides.

ObjectiveTo compare the efficacy and safety of acupuncture combined with auricular acupoints patches and nicotine transdermal patch in treating moderate to severe nicotine dependence. MethodsIn a rando-mized controlled trial， 64 quit smoking voluntary subjects with moderate to severe nicotine dependence were randomly divided at a ratio of 1∶1 into a treatment group and a control group， with 32 cases in each group. The treatment group was given acupuncture combined with auricular acupoints patches， twice weekly， four weeks as a course for two courses. The control group was given nicotine transdermal patch， one patch per day for 24 hours， 8 weeks. The cure rate was assessed after treatment and at follow-up （the 16th week after treatment）.The daily smoking volume， exhaled carbon monoxide （CO） value， Nicotine Dependence Scale （FTND）， Minnesota Nicotine Withdrawal Symptoms Scale （MNWS）， and Pittsburgh Sleepiness Index Inventory （PSQI） were evaluated before and after treatment and at follow-up， and adverse effects were recorded. ResultsIn terms of the cure rate， there were both six cured cases （20%） after treatment and at follow-up in the treatment group， while in the control group， seven （23.3%） and five （16.7%） patients were cured after treatment and at follow-up， respectively， with no statistically significant differences between the two groups both after treatment and at follow-up （P＞0.05）. The daily smoking volume and exhaled CO value significantly decreased after treatment and at follow-up in both groups （P＜0.05）， but were not significantly different between the groups after treatment and at follow-up （P＞0.05）. After treatment and at follow-up， FTND， MNWS， and PSQI scores were significantly reduced in both groups compared with those before treatment （P＜0.05）. There was no statistically significant difference in the FTND scale scores between the two groups after treatment and at follow-up （P＞0.05）， while the MNWS and PSQI scale scores were lower in the treatment group than in the control group （P＜0.05）. ConclusionAcupuncture combined with auricular acupoint patches for moderate to severe nicotine dependence has comparable effect with the first-line drug nicotine patch in terms of increasing the cure rate and decreasing the degree of nicotine dependence， and is superior to nicotine patch in terms of relieving withdrawal symptoms and improving sleep， with stable long-term effect.

To unravel the genetic mechanisms of disease and physiological traits, it requires comprehensive sequencing analysis of large sample size in Chinese populations. Here, we report the primary results of the Chinese Academy of Sciences Precision Medicine Initiative (CASPMI) project launched by the Chinese Academy of Sciences, including the de novo assembly of a northern Han reference genome (NH1.0) and whole genome analyses of 597 healthy people coming from most areas in China. Given the two existing reference genomes for Han Chinese (YH and HX1) were both from the south, we constructed NH1.0, a new reference genome from a northern individual, by combining the sequencing strategies of PacBio, 10× Genomics, and Bionano mapping. Using this integrated approach, we obtained an N50 scaffold size of 46.63 Mb for the NH1.0 genome and performed a comparative genome analysis of NH1.0 with YH and HX1. In order to generate a genomic variation map of Chinese populations, we performed the whole-genome sequencing of 597 participants and identified 24.85 million (M) single nucleotide variants (SNVs), 3.85 M small indels, and 106,382 structural variations. In the association analysis with collected phenotypes, we found that the T allele of rs1549293 in KAT8 significantly correlated with the waist circumference in northern Han males. Moreover, significant genetic diversity in MTHFR, TCN2, FADS1, and FADS2, which associate with circulating folate, vitamin B12, or lipid metabolism, was observed between northerners and southerners. Especially, for the homocysteine-increasing allele of rs1801133 (MTHFR 677T), we hypothesize that there exists a "comfort" zone for a high frequency of 677T between latitudes of 35-45 degree North. Taken together, our results provide a high-quality northern Han reference genome and novel population-specific data sets of genetic variants for use in the personalized and precision medicine.

Objective: To study the effect of ketogenic diet (KD) on vascular endothelial function in children with intractable epilepsy. Methods: Clinical informations of 14 children with intractable epilepsy in Fujian Medical University Affiliated Union Hospital from May 2014 to March 2018 were collected.Their blood index values were tested and retested before and after 3 months of KD treatment, including triglycerides (TG), total cholesterol (TC), high-density lipoprotein (HDL), low density lipoprotein (LDL), nitric oxide (NO), endothelin-1 (ET-1), and von Willebrand factor (vWF). These data were statistically analyzed by using repeated measurement analysis of variance. Results: (1)Changes in blood lipid levels: the levels of TG and TC increased slightly [(1.08±0.14) mmol/L, (5.19±0.64) mmol/L vs.(0.97±0.10) mmol/L, (4.57±0.29) mmol/L]and the level of HDL decreased slightly [(1.19±0.08) mmol/L vs.(1.31±0.08) mmol/L]after 3 months of KD treatment, but the differences were not statistically significant in the above indexes (all P>0.05). The level of LDL before KD was significantly lower than that after 3 months of KD [(2.93±0.25) mmol/L vs.(3.73±0.40) mmol/L ], and the difference was statistically signi-ficant(P=0.034). (2)Assessment of vascular endothelial function: compared with before KD, all the levels of NO [(60.84±5.29) μmol/L vs.(66.45±5.39) μmol/L ], ET-1 [(1.24±0.30) ng/L vs.(2.13±0.78)ng/L] and vWF [(150.53±12.97) μg/L vs.(137.57±13.10) μg/L]had no statistically significant changes after 3 months of KD(all P>0.05). Conclusions KD treatment lasting 3 months in children with intractable epilepsy can raise the level of LDL, but can′t change the vascular endothelial function.
