Self-reported quality of life in patients with coronary heart disease and analysis of the associated factors / 中华内科杂志

Objective: To investigate the quality of life and associated factors in patients with coronary heart disease (CHD) in China. Methods: A cross-sectional study of 25 provinces and cities in China was performed from June to September 2020. A questionnaire was used to collect the socio-demographic and clinical information of patients with CHD, while the European Five-dimensional Quality of Life Scale (EQ-5D) was used to assess the quality of life. Multiple linear regression model was performed to analyze the associated factors. Results: The median age of the 1 075 responders was 60 (52, 67) years, and 797 (74.1%) were men. The EQ-5D and EQ-VAS indices were 0.7 (0.5, 0.8) and 60.0 (40.0, 80.0). Among the five dimensions in the quality of life scale, the frequency of anxiety/depression was the highest (59.8%), while problems in self-care was the lowest (35.8%). In the multiple linear regression model, female, increasing age, obesity, comorbidity(ies), anxiety/depression, social media channels, and receiving the CABG therapy were associated with the lower EQ-5D index (all P<0.05). In addition, increasing age, obesity, comorbidity (ies), depression, anxiety and depression, social media channels, and receiving the CABG therapy were associated with lower EQ-VAS index (all P<0.05). Conclusion: Over half of the patients with CHD in China have a low quality of life, which is related to gender, age, obesity, treatment pathway, the presence or absence of comorbidity (ies), and psychological state. In addition to managing the adverse effects of traditional socio-demographic factors on the quality of life, clinical practices should pay attention to the psychological state of patients. Moreover, establishing a WeChat group for doctor-patient communication could improve the quality of life of CHD patients.

Effects of Decitabine Combined with Anlotinib on Proliferation and Apoptosis of Multiple Myeloma Cells / 中国实验血液学杂志

OBJECTIVE@#To investigate the biological effects and its relative mechanism of decitabine combined with anlotinib on multiple myeloma cells.@*METHODS@#The human MM cell lines and primary cells were treated with different concentrations of decitabine, anlotinib, and decitabine+anlotinib, respectively. The cell viability was detected and combination effect was calculated by CCK-8 assay. The apoptosis rate was measured by flow cytometry and the level of c-Myc protein was determined by Western blot.@*RESULTS@#Both decitabine and anlotinib could effectively inhibit the proliferation and induce the apoptosis of MM cell lines NCI-H929 and RPMI-8226. The effect of combined treatment on the inhibition of cell proliferation and induction of apoptosis was stronger than that of single-drug treatment. The combination of the two drugs also showed strong cytotoxicity in primary MM cells. Decitabine and anlotinib could down-regulate the level of c-Myc protein in MM cells and the c-Myc level in the combination group was the lowest.@*CONCLUSION@#Decitabine combined with anlotinib can effectively inhibit the proliferation and induce apoptosis of MM cells, which provides a certain experimental basis for the treatment of human MM.

HIV-1 Transmission among Injecting Drug Users is Principally Derived from Local Circulating Strains in Guangxi, China / 生物医学与环境科学（英文）

OBJECTIVE@#The mode of human immunodeficiency virus (HIV) transmission via injection drug use (IDU) still exists, and the recent shift in IDU-related transmission of HIV infection is largely unknown. The purpose of this study was to analyze the spatiotemporal sources and dynamics of HIV-1 transmission through IDU in Guangxi.@*METHODS@#We performed a molecular epidemiological investigation of infections across Guangxi from 2009 to 2019. Phylogenetic and Bayesian time-geographic analyses of HIV-1 sequences were performed to confirm the characteristics of transmission between IDUs in combination with epidemiological data.@*RESULTS@#Among the 535 subjects, CRF08_BC (57.4%), CRF01_AE (28.4%), and CRF07_BC (10.7%) were the top 3 HIV strains; 72.6% of infections were linked to other provinces in the transmission network; 93.6% of sequence-transmitted strains were locally endemic, with the rest coming from other provinces, predominantly Guangdong and Yunnan; 92.1% of the HIV transmission among people who inject drugs tended to be transmitted between HIV-positive IDUs.@*CONCLUSION@#HIV recombinants were high diversity, and circulating local strains were the transmission sources among IDUs in Guangxi. However, there were still cases of IDUs linked to other provinces. Coverage of traditional prevention strategies should be expanded, and inter-provincial collaboration between Guangxi, Yunnan, and Guangdong provinces should be strengthened.

Prenatal diagnosis of monogenic skeletal disorders in 22 pedigrees / 中华内分泌代谢杂志

Objective:To evaluate the clinical value of prenatal molecular diagnostic technology in preventing hereditary diseases through analysis of prenatal diagnostic characteristics in 22 monogenic skeletal disorders pedigrees.Methods:This study retrospectively analyzed prenatal molecular diagnostic results of 22 pedigrees with monogenic skeletal disorders who were admitted to Department of Osteoporosis and Bone Diseases in our hospital from January 2014 to July 2021.Results:Among 22 pedigrees, there were 10 pedigrees with X-linked hypophosphatemic rickets due to PHEX gene mutations, in which 8 fetuses were found to carry pathogenic variants; 6 pedigrees with osteopetrosis, including 3 cases of CLCN7 gene mutation, 2 TCIRG1 gene mutation, and 1 CTSK gene mutation, were detected to have 2 affected fetuses and 1 carrier. There were 4 cases of osteogenesis imperfecta, including 2 cases of COL1A1 gene mutation, 1 case of COL1A2 gene mutation, and 1 case of SERPINF1 gene mutation, in which 1 affected fetus and 1 carrier were found; only one case of osteoarthritis with mild chondrodysplasia caused by COL2A1 gene mutation was found to harbor pathogenic variant in fetus; 1 case of hypophosphatasia due to ALPL gene mutation was not detected to carry pathogenic variant in fetus. By the time of follow-up, all 12 affected fetuses were terminated, and the remaining 10 fetuses except for one case still in pregnancy were born in good condition.Conclusion:Prenatal molecular diagnosis may confirm whether the fetus carries pathogenic variants at the first and second trimesters. For monogenic skeletal disorders that comply with Mendel′s law of separation, prenatal diagnosis can be determined by calculating the probability of recurrence of offspring. In addition, for families with de novo mutations in the offspring, it is necessary to pay attention to whether there are mosaic mutations in the parents.

In the control group, scores after follow-up were slightly higher than those at baseline(29.4±11.4 vs.27.9±10.1, P<0.001). The increase in scores before and after intervention was greater in the intervention group than in the control group( P<0.001). Baseline score, group designation, history of drinking and diabetes impacted the scores in middle-aged and elderly women, while other factors did not.Most middle-aged and older people preferred texts illustrated with pictures, and older people were more receptive to videos. Conclusions:The new science promotion method is beneficial to bone health management, can improve bone health awareness in middle-aged and elderly people.

Detection and molecular characteristics of bovine rotavirus A in dairy calves in China

Background@#Bovine group A rotavirus (BoRVA) is a major cause of severe gastroenteritis in newborn dairy calves. Only one study has investigated the G and P genotypes among dairy calves in a few regions of China, which were G6 and P[5]. Therefore, data on the prevalence and molecular characteristics of BoRVA in dairy calves in China remains limited. @*Objectives@#The purpose of this study was to investigate the prevalence and molecular characteristics of BoRVA in dairy calves in China. @*Methods@#269 dairy calves diarrheic samples from 23 farms in six provinces in China were collected to detect BoRVA using reverse transcription polymerase chain reaction. @*Results@#71% of samples were determined to be BoRVA-positive. Two G genotypes (G6, G10) and two P genotypes (P[1], P[5]) were identified, and G6P[1] BoRVA was the predominant strain. Moreover, the VP7 and VP4 gene sequences of these dairy calf BoRVA strains revealed abundant genetic diversity. Interestingly, eight out of 17 complete G6 VP7 sequences were clustered into G6 lineage VI and analysis showed the strains were closely related to Chinese yak BoRVA strains. @*Conclusions@#The results of this study show that BoRVA circulates widely among dairy calves in China, and the dominant genotype in circulation is G6P[1], first report on molecular characteristics of complete P[5] VP4 genes in chinese dairy calves. These results will help us to further understand the prevalence and genetic evolution of BoRVA among dairy calves in China and, thus, prevent the disease more effectively.

Effect of calcium dobesilate in preventing contrast-induced nephropathy in patients with diabetes and chronic kidney disease

OBJECTIVES: This study assessed the protective effect of calcium dobesilate against contrast-induced nephropathy (CIN) after coronary angiography (CAG) or percutaneous coronary intervention (PCI) in patients with diabetes and chronic kidney disease (CKD). METHODS: A total of 130 patients with diabetes and CKD estimated glomerular filtration rate: 30-90 mL/min/1.73m2 were enrolled and included in the analysis. They were divided into experimental (n=65) and control groups (n=65). Patients in the experimental group were administered oral calcium dobesilate (500 mg) three times daily for 2 days before and 3 days after the procedure. The serum creatinine (SCr), cystatin C (Cys C), and neutrophil gelatinase-associated lipocalin (NGAL) levels were measured before and after the procedure. RESULTS: The mean SCr level at 24h after the procedure was found to be significantly lower in the experimental group than in the control group (79.1±19.6 μmol/L vs. 87.0±19.3 μmol/L, p=0.023). However, the Cys C and NGAL levels were not significantly different between the two groups at all measurement time points (all p>0.05). The incidence of CIN defined by the SCr level was significantly lower in the experimental group than in the control group (3 [4.6%] vs. 13 [20.0%], p=0.017). However, the incidence of CIN defined by the Cys C level was not statistically different between the two groups (7 [10.8%] vs. 7 [10.8%], p=1.000). CONCLUSIONS: This study revealed that calcium dobesilate has no preventive effect against CIN in patients with diabetes and CKD.

Advances in Studies on Chinese Materia Medica for Treatment of Sepsis Based on NF-κB Signal Pathway / 中国实验方剂学杂志

Sepsis is a kind of systemic inflammatroy response syndrome (SIRS) induced by severe infection,operation,and trauma,with high mortality rate,treatment cost,and high consumption of medical resources.It has caused a great burden to the medical industry and even the national economy.Therefore,it is urgent to find effective treatment methods for sepsis.At present,the sepsis has been treated with certain drugs pointing at its pathogenesis,such as antibiotics,glucocorticoids,and vasoactive drugs.,but the therapeutic effect is not ideal,with many side effects,poor prognosis,and high clinical mortality.Based on the overall macro-dialectical thinking mode,and with the unique effect and low side effect,traditional Chinese medicine (TCM) has attracted the attention from researchers and clinicians around the world for treatment of sepsis.In recent years,some traditional Chinese medicine prescriptions,Chinese patent medicines,single Chinese medicines and active ingredients are increasingly used as new drugs to prevent and treat sepsis.Such treatment methods have been widely recognized and have reduced the mortality and inflammatory indexes of patients to a certain extent,playing an important role in the prevention and treatment of sepsis.In this paper,the actions of nuclear factor kappa B (NF-κB) signal pathway in sepsis as well as the advances in research of NF-κB signal pathway-related proteins in Chinese medicine for sepsis were reviewed.

Risk assessment of pesticide residues in domestic ginsengs / 中国中药杂志

The study aims at taking risk assessment of pesticide residues in ginseng and high risk pesticides were picked up in order to provide a scientific basis for the establishment of maximum residue limits(MRLs) for pesticides in ginseng. Residues of 246 pesticides in 80 ginseng samples collected from different place were detected by GC-MS/MS and LC-MS/MS method. Acute and chronic intake risks were evaluated by using deterministic approach, and the matrix ranking developed by the Veterinary Residues Committee of the United Kingdom was referred to assess risk score of pesticides. The 25 kinds of pesticide residues were detected in ginseng samples, the detection rate of quintozene(PCNB) was 78%, which was the most frequently detectable pesticide. The chronic dietary intake risks of 25 pesticide residues expressed as %ADI were 0.00%-2.6%, and their acute dietary intake risks expressed as %ARfD were 0.00%-104.2%. Among them the acute dietary intake risks of PCNB was 104%,which was the highest. The 25 pesticides were divided into 3 groups by risk score, high risk group(4 pesticides), medium risk group(6 pesticides), and low risk group(15 pesticides). Hexachlorobenzene, phorate, PCNB and BHC were classified as high risk group. It is necessary and effective to establish the limit of residual organic chlorine in ginseng from Chinese Pharmacopoeia(2015 edition). MRLs for PCNB and hexachlorobenzene in ginseng were proposed to be revised based on the results of risk assessment.

Analysis of genomic characteristics of influenza A (H1N1) pdm09 viruses in Inner Mongolia, 2013-2017 / 中华实验和临床病毒学杂志

Objective@#To evaluate the effect of vaccine and provide scientific evidence for prevention and control of influenza virus, this study aims to analyze the characteristics of genomic variation of influenza A (H1N1) pdm09 viruses in Inner Mongolia.@*Methods@#The 16 viral strains were selected randomly according to the influenza A (H1N1) pdm09 viruses isolated from network laboratories in Inner Mongolia, 2013-2017. The hemagglutinin(HA) and neuraminidase(NA) genomic sequences were obtained by using RT-PCR and sequencing, and genomic characteristics were analyzed via bioinformatics.@*Results@#Compared to the A/California/07/2009 vaccine strain, the relatively obvious variation of antigen of influenza A (H1N1) pdm09 viruses in Inner Mongolia since 2014, and the vaccine provided a poor protection to influenza A (H1N1) pdm09 virus infection, while the A/Michigan/45/2015 vaccine strain recommended by WHO recently has a satisfactory protective effects. Several viral isolates from Inner Mongolia increased the binding force of virus in human upper respiratory tract because of D222N and D222G substitution within HA. E119K and H275Y substitution within NA gene of viral strains, suggesting that the viruses were resistant to NA inhibitors.@*Conclusions@#The influenza A (H1N1) pdm09 viruses had gradual variations as time went on, and the WHO recommended vaccine was relatively lagging. Virulent strains and drug-resistant strains appeared in the population, and the genetic characteristics of influenza virus surveillance should be strengthened to find the new mutants of virus in time, which provide evidence for the prevention and control of influenza.

Comparison of the efficacy and safety between decitabine combined with all-trans retinoic acid or half dose priming regimen in the treatment of elderly patients with myelodysplastic syndromes and acute myeloid leukemia / 医学研究生学报

Objective Decitabine (DAC) combined with the half dose priming regimen (HDPR) is a common treatment of myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML) in the elderly. This study was to compare the clinical effect and safety of DAC combined with all-trans retinoic acid (ATRA) versus DAC plus HDPR in the treatment of MDS with excess of blasts (MDS-EB) or AML in elderly patients. Methods We retrospectively analyzed 48 elderly patients (≥60 years) with myeloid neoplasms (AML, MDS-EB-1 or MDS-EB-2) ineligible for standard chemotherapy treated in our hospital from January 2014 to October 2018, 22 by DAC+ATRA (group A) and the other 26 by DAC+HDPR (group B). We compared the overall response rate (ORR), overall survival (OS) and adverse events between the two groups of patients. Results No statistically significant difference was observed between groups A and B in ORR (86.4% vs 76.9%, P = 0.643) or median OS (26.2 vs 24.9 mo, P = 0.920). The median time to response was significantly longer in group A (2 courses) than in B (1 course) (P = 0.006). Compared with group A, group B showed remarkably lower incidence rates of grade-3 to -4 cytopenia (54.5% vs 84.6%, P = 0.029) and infection (45.5% vs 76.9%, P = 0.037), longer duration of neutropenia (P < 0.05), and higher volumes red blood cell infusion and platelet infusion (P < 0.05). There was no statistically significant difference in the incidence rate of bleeding between the two groups (P = 0.643). Conclusion DAC+ATRA and DAC+HDPR have comparable clinical effects on myeloid neoplasms in elderly patients, but the former is safer and better tolerated while the latter can achieve a more rapid response.

A clinical study of Proteus syndrome caused by a mosaic somatic mutation in AKT1 gene / 中华内科杂志

Objective Proteus syndrome is a rare disease. The aim of the present study was to analyze the clinical characteristics and gene mutations of Proteus syndrome with a case report and relevant literature review. Methods Clinical data of the patient with Proteus syndrome were collected in detail and biochemical measurements and radiological examinations were conducted. Tissues from phalanges with lesions were obtained to extract DNA, and Sanger sequencing of AKT1 gene was carried on. The pathogenic mutation was further tested in peripheral blood samples of the patient, his parents and 250 healthy volunteers. Orthopaedic surgery was performed on the affected limbs of the patient. Results The patient was presented with progressive overgrowth of the right extremity, scoliosis, cerebral connective tissue nevus and lower extremity venous. A heterozygous mutation of AKT1 gene (c. 49G>A) was identified in DNA extracted from the affected bone tissue of the patient, but not be found in genomic DNA of peripheral blood samples from the patient, his parents and 250 healthy volunteers. Movement function of the affected limb improved significantly after the operations. Conclusions The prominent features of Proteus syndrome are overgrowth of one extremity and cerebral connective tissue nevus. A mosaic somatic mutation of AKT1 gene is one of the pathogenic mutations for Proteus syndrome, and orthopedic surgery may be a good way to improve symptoms of the disease.

To explore influence of ultrasound‐guided lauromacrogol foam sclerotherapy on peripheral blood levels of counting of endothelial cells (CEC) , endothelin (ET)‐1 and nitric oxide (NO) in patients with sa‐phenous vein varicosis .Methods : A total of 90 patients with saphenous vein varicosis were randomly and equally di‐vided into lauromacrogol group (received ultrasound‐guided lauromacrogol foam sclerotherapy ) and routine treat‐ment group (received routine stripping ).Peripheral blood levels of CEC , ET‐1 and NO were observed and com‐pared between two groups before and after surgery , and therapeutic effect and incidence of complications were eval‐uated.Results : Compared with routine treatment group , there were significant reductions in surgery time [ (81. 79 ± 16.88) min vs .(40.55 ± 10. 19) min] , hospitalization time [(3.94 ± 1.36) d vs.(2. 17 ± 1.31) d] and hospital‐ization fee [ (7640. 15 ± 1025.11) RMB vs.(3998.89 ± 910. 67 ) RMB ] in lauromacrogol group , P＝ 0.001 all. Compared with routine treatment group after surgery , there were significant reductions in incidence rate of total complications (17.78% vs .4. 44%) , percentage of patient＇s condition class IV (17. 78% vs.4.44%) , peripheral blood levels of CEC [ (5562. 48 ± 1194. 73)／L vs.(4655.87 ± 1209. 88)／L] and ET‐1 [ (70. 32 ± 10.30) ng／L vs. (62.95 ± 13.78) ng／L] , and significant rise in percentage of patient’ s condition class I (6.67% vs.25. 00%) and peripheral blood NO level [(1.27 ± 0.42) μmol／L vs.(1. 59 ± 0.51) μmol／L] in lauromacrogol group , P＜0. 05 or＜0. 01. Conclusion : Ultrasound‐ guided lauromacrogol foam sclerotherapy can significantly increase therapeutic effect , improve vascular endothelial function in patients with saphenous vein varicosis .And its complications are few .

Effect of Additional Chromosomal Abnormalities on the Outcome of CML-CP Patients Receiving TKI Therapy / 中国实验血液学杂志

<p><b>OBJECTIVES</b>To explore the effect of additional chromosomal abnormalities on the prognosis and outcome of CML-CP patients receiving imatinib therapy.</p><p><b>METHODS</b>The clinical and genetic data of 589 CML-CP patients receiving imatinib treatment between May 2009 and October 2014 in the 1st Affiliated Hospital of Soochow University were analyzed, the 589 patients were divided into 5 groups according to the karyotypes at the initial diagnosis. The OS(overall survival), PFS (progression-free survival), EFS (event-free survival), Cumulative MMR (major molecular remission) and Cumulative CCyR (complete cytogenetic remission) were calculated by using the Kaplan-Meier method and compared by using the log-rank text by Graphpad 6.0. The χ test was used to compare the frequency of optimal molecular response at 3, 6, 12 months among the 5 groups.</p><p><b>RESULTS</b>There was significant difference about the frequency of optimal molecular response at 3 and 6 months between CML-CP patients with additional chromosomal abnormalities and those with classic t(9;22) ［50%（12/24） vs. 73.94%(261 /353), P<0.05; 50%(10 /20) vs. 72.05%(232 /322) (P<0.05)］, and the same significant difference was found at 6 months between the group with variant translocations and that with classic t(9;22) ［53.3% (16 /30) vs. 72.05%(232 /322) (P<0.05)］. The P values of cumulative CCyR (P<0.05) and EFS (P<0.01) for 4 years were statistically significant between CML-CP patients with additional chromosomal abnormalities and the other 4 groups. Compared one to another, there was the significant difference in cumulative CCyR and EFS for 4 years between CML-CP patients with additional chromosomal.abnormalities and those with classic t(9;22) (47.25% vs. 84.01%)(P<0.05); (75.03% vs. 90.01%)(P<0.01).</p><p><b>CONCLUSION</b>The additional chromosomal abnormalities influence the outcome of CML-CP patients receiving imatinib treatment, which make poor prognosis.</p>
