Objective:To investigate the characteristics of voice-personality perception in blind persons and its relationship with their self-evaluation of personality.Methods:A total of 68 blind persons and 68 sighted peers were respectively recruited to rated 30 short voice recordings on traits of voice-personality perception(including maturi-ty,sunshine,cuteness,indolence,seriousness,simpleness and honestness,gentleness,kindness,self-confidence and optimism).Meanwhile,data on self-evaluations of the above participants and speakers in those recordings,along with acquaintance's ratings on speakers'personality were collected.Results:The research found that compared to sighted peers,blind individuals had a lower voice-personality rating on speakers in traits of sunshine,seriousness,gentleness,kindness,self-confidence and optimism(Ps＜0.005).It also detected that the voice-personality ratings on these speakers by blind individuals had a greater deviation from the rating by these speakers/acquaintances in sunshine;gentleness;kindness and optimism(Ps＜0.005).Meanwhile,blind individuals had lower self-rating on personality in sunshine and optimism(Ps＜0.005).Furthermore,self-ratings of sunshine from blind individuals were positively associated with their voice-personality ratings of optimism on speakers(r=0.28,P＜0.05),and their self-ratings of optimism were positively related to their voice-personality ratings of sunshine and self-confi-dence on speakers(r=0.27,0.28,Ps＜0.05).Conclusion:The study shows that blind individuals have lower voice-personality ratings on others than their sighted peers,which might be due to some of their more negative per-sonality characteristics.

Objective:To observe the clinical efficacy and safety of Tongren Niuhuang Qingxin Pills combined with telmisartan tablets in the treatment of hypertensive vertigo syndrome of phlegm-heat disturbance.Methods:Randomized controlled trial was conducted. Totally 80 patients with hypertension vertigo and phlegm-heat disturbance syndrome were selected from March 2021 to August 2022 at Beijing Tongrentang Hospital of Traditional Chinese Medicine as the observation objects. They were randomly divided into two groups using a random number table method, with 40 cases in each group. The control group received oral telmisartan tablets, while the experimental group received Tongren Niuhuang Qingxin Pills in addition to the control group. Both groups were treated for 28 days and followed up for 1 month. The patients' room blood pressure before and after treatment was measured, and TCM syndrome scores were evaluated. The dizziness assessment rating scale (DARS) was used to evaluate the severity of dizziness, adverse reactions during treatment were recorded, drug safety was observed, and clinical efficacy was evaluated.Results:The total effective rate of the experimental group was 85.0% (34/40), and that of the control group was 7.5% (3/40), with statistical significance between the two groups ( χ2=48.32, P<0.001). Compared with before treatment, the experimental group had SBP [(136.63 ± 6.01) mmHg vs. (159.30 ± 9.01) mmHg, t=-21.00] and DBP [(84.48 ± 4.36) mmHg vs. (95.30 ± 3.75) mmHg, t=-13.80] after treatment; after treatment, SBP [(137.34 ± 6.39) mmHg vs. (158.00 ± 10.06) mmHg, t=-5.28] and DBP [(86.08 ± 4.43) mmHg vs. (95.18 ± 6.61) mmHg, t=-8.09] decreased in the control group ( P<0.01), but there was no statistical significance between the two groups after treatment ( P>0.05). After treatment, the TCM syndrome scores in the experimental group (8.68 ± 3.39 vs. 15.12 ± 3.03, Z=-6.61) were lower than those in the control group ( P<0.001), and DARS score [(8.53 ± 3.93) vs. (12.20 ± 3.95), Z=-3.63] was lower than that in the control group ( P<0.001). After treatment, the therapeutic effect index of TCM syndromes in the experimental group improved compared to before treatment in the same group. The therapeutic effect index of each symptom, from high to low, was as follows: rotation of oneself or visual objects>numbness of limbs>dry stool>dizziness and dizziness>liking cold drinks>bitter and dry mouth>red urine>red tongue, yellow coating, and greasy tongue>vomiting sticky and turbid phlegm>tinnitus>smooth pulse. There were no significant adverse reactions during the treatment of the two groups. Conclusion:Tongren Niuhuang Qingxin Pills combined with telmisartan can reduce the blood pressure of patients with hypertensive vertigo syndrome of phlegm-heat disturbance, improve the vertigo symptoms and TCM syndromes of patients, and the efficacy evaluation is superior to that of telmisartan alone.

Objective:To sinicize the Index of Dental Anxiety and Fear (IDAF-4C +), and to test its reliability and validity. Methods:According to the Brislin translation model, the literal translation, back translation, cultural adjustment and pre-investigation of the scale were carried out to form the Chinese version of the IDAF-4C + Scale, and the convenience sampling method was used to investigate the outpatients of the Affiliated Stomatological Hospital of Nanchang University from October 2021 to January 2022 to verify the reliability and validity of the scale. Results:The Chinese version of the IDAF-4C + Scale consisted of three modules (core anxiety module, fear module and stress module), with a total of 23 items, of which the core anxiety module included cognitive, physiological, behavioral and emotional dimensions. The content validity index of each item was 0.8-1.0, and the content validity index of the total scale was 0.913; the construct validity was 0.903, and a common factor was extracted by exploratory factor analysis of anxiety module. The contribution rate of cumulative variance was 72.037%. The results of confirmatory factor analysis showed that the model fitted well and all the adaptation indexes were up to the standard. Using the Modified Dental Anxiety Scale (MDAS) as the criterion, the correlation coefficient between IDAF-4C module and MDAS was 0.66, the Cronbach α coefficient of the scale was 0.913, and the test-retest reliability was 0.923. Conclusions:The Chinese version of the IDAF-4C + Scale has good reliability and validity and can be used as a tool to measure and evaluate the level of dental anxiety and fear in oral patients.

Objective To investigate the application prospect of the most extensive genome engineering pig internationally in preclinical xenotransplantation. Methods Porcine endogenous retrovirus (PERV) knockout combined with 3 major heterologous antigen gene knockouts and 9 humanized genes for inhibition of complement activation, regulation of coagulation disorders, anti-inflammatory and anti-phagocytosis were transferred into a pig (PERV-KO/3-KO/9-TG) as a donor, and the heart, liver and kidney were obtained and transplanted to 3 Rhesus macaque recipients respectively to establish a preclinical research model of pig-to-Rhesus macaque xenotransplantation. The functional status of xenografts after blood flow reconstruction was observed and the survival of recipients was summarized. The hemodynamics of xenografts were monitored. The change of hematological indexes of each recipient was compared. The histopathological manifestation of xenografts was observed. Results After the blood flow was reconstructed, all xenografts showed ruddy color, soft texture and good perfusion. The transplant heart, liver and kidney showed full arterial and venous blood flow and good perfusion at 1 d after operation. The postoperative survival time of heart, liver, and kidney transplant recipients was 7, 26, and 1 d, respectively. The levels of creatine kinase, creatine kinase isoenzyme, and lactate dehydrogenase increased in heart transplant recipient at 1 d after operation, and gradually recovered to near normal levels at 6 d after operation. All indexes increased sharply at 7 d after operation. The level of aspartate aminotransferase increased in liver transplant recipients at 2 d after operation, and the alanine aminotransferase basically returned to normal at 10 d after operation, but the total bilirubin continued to increase. Both aspartate aminotransferase and alanine aminotransferase increased at 12 d after operation, and reached a peak at 15 d after operation. The kidney transplant recipient developed mild proteinuria at 1 d after operation, and died of sudden severe arrhythmia. Histopathology showed that the tissue structure of cardiac and renal xenografts was close to normal, and liver xenografts presented with patchy necrosis, the liver tissue structure was disordered, accompanied by inflammatory damage, interstitial hemorrhage and thrombotic microangiopathy. Conclusions PERV-KO/3-KO/9-TG pig shows advantages in overcoming hyperacute rejection, mitigating humoral rejection and coagulation dysregulation. However, whether it can be used as potential donor for clinical xenotransplantation needs further evaluation.

Objective:To establish a disease risk prediction model for the newborn screening system of inherited metabolic diseases by artificial intelligence technology.Methods:This was a retrospectively study. Newborn screening data ( n=5 907 547) from February 2010 to May 2019 from 31 hospitals in China and verified data ( n=3 028) from 34 hospitals of the same period were collected to establish the artificial intelligence model for the prediction of inherited metabolic diseases in neonates. The validity of the artificial intelligence disease risk prediction model was verified by 360 814 newborns ' screening data from January 2018 to September 2018 through a single-blind experiment. The effectiveness of the artificial intelligence disease risk prediction model was verified by comparing the detection rate of clinically confirmed cases, the positive rate of initial screening and the positive predictive value between the clinicians and the artificial intelligence prediction model of inherited metabolic diseases. Results:A total of 3 665 697 newborns ' screening data were collected including 3 019 cases ' positive data to establish the 16 artificial intelligence models for 32 inherited metabolic diseases. The single-blind experiment ( n=360 814) showed that 45 clinically diagnosed infants were detected by both artificial intelligence model and clinicians. A total of 2 684 cases were positive in tandem mass spectrometry screening and 1 694 cases were with high risk in artificial intelligence prediction model of inherited metabolic diseases, with the positive rates of tandem 0.74% (2 684/360 814)and 0.46% (1 694/360 814), respectively. Compared to clinicians, the positive rate of newborns was reduced by 36.89% (990/2 684) after the application of the artificial intelligence model, and the positive predictive values of clinicians and artificial intelligence prediction model of inherited metabolic diseases were 1.68% (45/2 684) and 2.66% (45/1 694) respectively. Conclusion:An accurate, fast, and the lower false positive rate auxiliary diagnosis system for neonatal inherited metabolic diseases by artificial intelligence technology has been established, which may have an important clinical value.

Many human genetic diseases, including Hutchinson-Gilford progeria syndrome (HGPS), are caused by single point mutations. HGPS is a rare disorder that causes premature aging and is usually caused by a de novo point mutation in the LMNA gene. Base editors (BEs) composed of a cytidine deaminase fused to CRISPR/Cas9 nickase are highly efficient at inducing C to T base conversions in a programmable manner and can be used to generate animal disease models with single amino-acid substitutions. Here, we generated the first HGPS monkey model by delivering a BE mRNA and guide RNA (gRNA) targeting the LMNA gene via microinjection into monkey zygotes. Five out of six newborn monkeys carried the mutation specifically at the target site. HGPS monkeys expressed the toxic form of lamin A, progerin, and recapitulated the typical HGPS phenotypes including growth retardation, bone alterations, and vascular abnormalities. Thus, this monkey model genetically and clinically mimics HGPS in humans, demonstrating that the BE system can efficiently and accurately generate patient-specific disease models in non-human primates.

Epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) are the key to the treatment of advanced non-small cell lung cancer (NSCLC),but there are various drug-resistant mutations in the latter stage.The first and second generation of EGFR-TKIs significantly prolong the survival of patients with EGFR-activated mutant tumors.The third generation of EGFR-TKIs effectively inhibit the progress of T790M mutant tumors.The fourth generation of EGFR-TKIs inhibit both L858R,T790M and L858R,T790M,C797S mutant tumors.Using circulating tumor DNA and exogenous RNA can effectively detect the mutation types of EGFR,and choose EGFR-TKIs therapy or combined chemotherapy according to the mutation types.

Tung tree (Vernicia fordii) is an economically important woody oil plant that produces tung oil rich in eleostearic acid. Here, we report a high-quality chromosome-scale genome sequence of tung tree. The genome sequence was assembled by combining Illumina short reads, Pacific Bio-sciences single-molecule real-time long reads, and Hi-C sequencing data. The size of tung tree gen-ome is 1.12 Gb, with 28,422 predicted genes and over 73％ repeat sequences. The V. fordii underwent an ancient genome triplication event shared by core eudicots but no further whole-genome duplication in the subsequent ca. 34.55 million years of evolutionary history of the tung tree lineage. Insertion time analysis revealed that repeat-driven genome expansion might have arisen as a result of long-standing long terminal repeat retrotransposon bursts and lack of efficient DNA deletion mechanisms. The genome harbors 88 resistance genes encoding nucleotide-binding sites;17 of these genes may be involved in early-infection stage of Fusarium wilt resistance. Further, 651 oil-related genes were identified, 88 of which are predicted to be directly involved in tung oil biosynthesis. Relatively few phosphoenolpyruvate carboxykinase genes, and synergistic effectsbetween transcription factors and oil biosynthesis-related genes might contribute to the high oil content of tung seed. The tung tree genome constitutes a valuable resource for understanding genome evolution, as well as for molecular breeding and genetic improvements for oil production.

OBJECTIVETo investigate the safety and efficacy of endoscopic duodenal valvectomy in the treatment of congenital duodenal membranous stenosis.

METHODSClinical data of two children with congenital duodenal membranous stenosis undergoing endoscopic duodenal valvectomy in our institute within October 2014 were analyzed retrospectively. This procedure was performed with Microknife XL and CRE balloon catheter through porous channel in the 9 mm flexible endoscope.

RESULTSThe first case was a 2-year-old boy who received two endoscopic operations including duodenal diaphragm resection and duodenal dilatation because of incision retraction. The second case was a 19-month-old gril who received once endoscopic duodenal valvectomy. Duodenal obstruction of these two children was relieved after operation. Postoperative x-rays showed no perforation. They could play in the floor 6 hours after operation without any complains, drink water 12 hours, take liquid diets 2 days and half solid food 3 days after operation. During follow-up a month after operation, the body weight gained was 1.5 and 1.0 kg respectively, and the dietary components was significantly improved.

CONCLUSIONEndoscopic duodenal valvectomy is feasible and effective in the treatment of congenital duodenal membranous stenosis.
