ABSTRACT

Objective To investigate the effect of high sodium diet on the prevalence and mortality of gastric cancer in Xi'an , and to provide reference for its clinical treatment and prevention. Methods A questionnaire survey was conducted on 604 inpatients in tertiary hospitals in Xi'an from 2018 to 2020, and data including medical history, medication use, daily sodium intake and gastric cancer incidence were collected. A one-year follow-up was completed, and all-cause mortality was recorded during the follow-up period. Results A total of 604 cases , there were 81 cases of gastric cancer and 523 cases of non-gastric cancer, with a prevalence rate of 13.41%. Among patients with gastric cancer, 49 (8.11%) were male and 32 (5.30%) were female. There were 9 cases (1.49%) aged 30-40 years, 14 cases (2.32%) aged 41-50 years, 27 cases (4.47%) aged 51-60 years and 31 cases (5.13%) aged 60 years and above. The gastric cancer and non-gastric cancer patients yielded no statistical difference in terms of age, gender and medical history (P>0.05), while the proportion of sodium intake was significantly higher in gastric cancer patients than in non-gastric cancer patients (P<0.05). Logistics analysis showed that high sodium diet was a risk factor for the development of gastric cancer (P<0.05). The proportion of high sodium diets was 40.89% (247/604) in all selected individuals, 72.84% (59/81) in gastric cancer patients and 35.95% (188/523) in non-gastric cancer patients. The proportion of patients on a high sodium diet demonstrated statistical difference between gastric cancer and non-gastric cancer patients (P<0.05). One-year follow-up showed that 58 of 81 gastric cancer patients survived (71.60%) and 23 died (28.40%), including 20 survivors (34.48%) and 17 deaths (73.91%) on a high-sodium diet. Significant difference was found in the proportion of patients on high sodium diet between dead and surviving gastric cancer patients (P<0.05). Conclusion The prevalence and mortality rate of gastric cancer caused by high sodium diet is high among residents in Xi'an , clinical guidance on sodium intake is of great importance to patients.

ABSTRACT

OBJECTIVES@#To study the changes in the distribution and drug resistance profiles of pathogens causing bloodstream infection after chemotherapy in children with acute lymphoblastic leukemia.@*METHODS@#The medical data were collected from the children with acute lymphoblastic leukemia who were admitted to the First Affiliated Hospital of Zhengzhou University between January 2015 and December 2020 and developed bloodstream infection after chemotherapy. The samples were divided into the first three years group and the next three years group according to the time of testing to investigate the differences in the distribution and drug resistance profiles of pathogens as time.@*RESULTS@#A total of 235 strains of pathogens were isolated, among which there were 159 Gram-negative strains (67.7%; mainly Escherichia coli and Klebsiella pneumoniae), 61 Gram-positive strains (26.0%; mainly Staphylococcus epidermidis), and 15 strains of fungi (6.4%; mainly Candida albicans). There were no significant differences between the first three years group and the next three years group in the detection rate of Gram-negative bacteria (68.8% vs 66.9%, P>0.05) or Gram-positive bacteria (29.2% vs 23.7%, P>0.05). Compared with the first three years group, the next three years group had significant increases in the detection rate of Streptococcus mitis (5.8% vs 0.0%, P<0.05) and fungi (9.4% vs 2.1%, P<0.05). There was no significant difference in the drug resistance rate of Gram-negative or Gram-positive bacteria between the two groups (P>0.05).@*CONCLUSIONS@#Enterobacteriaceae bacteria are the main pathogens of bloodstream infection after chemotherapy in children with acute lymphoblastic leukemia, while the detection rates of Streptococcus mitis and fungi tend to increase as time, which needs to be taken seriously in clinical practice.

ABSTRACT

The paper introduces the clinical experience of GAO Hong in treatment of tic disorder. GAO Hong believes that tic disorder results from the primary qi deficiency and mind disturbance. Acupuncture for cultivating the primary and regulating the mind is proposed specially for tic disorder. This acupuncture technique focuses on harmonizing and regulating governor vessel and conception vessel. In clinical practice, the conception vessel acupoints on the abdomen and the governor vessel acupoints on the head are selected particularly, e.g. Zhongwan (CV 12), Xiawan (CV 10), Qihai (CV 6) and Guanyuan (CV 4) on the abdomen; Baihui (GV 20), Shenting (GV 24), Benshen (GB 13) and Yintang (GV 24+) on the head. The needling sequence and the insertion depth are emphasized, which affect the curative effect and GV 20 is generally punctured first. Besides, considering to the type of disorder and the affected site, tic disorder is treated in view of both syndrome/pattern differentiation and symptom differentiation.

ABSTRACT

ObjectiveTo investigate the level of serum antibodies in COVID-19 patients six months after discharge, and to provide data to evaluate the duration of IgM, IgG and neutralizing antibody titers in the patients. MethodsEnzyme-linked immunosorbent assay (ELISA) was used to determine the antibody levels of IgM and IgG, and the new coronavirus live virus neutralization test was used to detect the neutralizing antibodies in the plasma of 181 recovered patients. ResultsThe IgG positive rate was 92.27% (167/181) in COVID-19 patients six months after discharge, while the lgM positive rate was 28.18% (51/181). Six months after hospital discharge, 117 recovered patients (64.64%) were positive for IgG antibodies and negative for IgM antibodies, indicating that they had produced stable antibodies. This result suggested that they had been infected with the new coronavirus (SARS-CoV-2) and were in the recovery stage. The positive detection rate of neutralizing antibodies was as high as 91.71%. ConclusionSix months after infection with SARS-CoV-2, IgG antibodies produced in the patients continue to exist, and the neutralizing antibodies maintain a high and stable level. Results of this study have important guiding significance for future research on the durability of new coronavirus antibodies.

ABSTRACT

Objective:To analyze the epidemiological characteristics and trend of stroke death among registered residents in Hexi District of Tianjin from 2007 to 2019,and to provide scientific basis for evaluation of comprehensive prevention and control strategies and measures of stroke. Methods:All death monitoring data of the residents was collected and the crude mortality, standardized mortality and annual percent change (APC) of stroke were obtained by statistical treatment. Results:A total of 15 235 stroke deaths were reported in Hexi District of Tianjin from 2007 to 2019,with an average annual mortality rate of 144.59/105. The rate was higher in males than in females (169.02/105 in males and 121.04/105 in females, P<0.001). The crude mortality rate showed an upward trend with the year (APC=1.51%, P<0.05). The standardized mortality rate showed a downward trend (APC=-1.39%, P<0.05). The crude mortality of ischemic stroke showed an upward trend with the year (APC=3.15%, P<0.01), and the trend change in standardized mortality rate had no statistical significance. The crude mortality and standardized mortality of hemorrhagic stroke showed a downward trend,with the mortality rate decreased at 2.43% per year and the standardized mortality rate decreased at the 4.50% per year (all P<0.05). Conclusion:Stroke is the main disease affecting the health of residents in Hexi District of Tianjin. Targeted measures should be taken to reduce the mortality of stroke. Stroke prevention and control should focus on winter and spring seasons, males, elderly people and patients with ischemic stroke.

ABSTRACT

Clinical data of 2 children with cystic fibrosis (CF) and Pseudomonas aeruginosa infection in the Department of Pediatrics of Sichuan Provincial People′s Hospital from April 2018 to June 2019 were retrospectively analyzed.Patient 1 was an 11-year-old girl with no history of recurrent respiratory infections. Pseudomonas aeruginosa was found in the first sputum culture.A large number of yellow and white secretions were visible under repeated fiberoptic bronchoscopy.Chest CT showed multiple spots and tree-in-bud signs around the bronchi of both lungs. CFTR gene test results revealed 3 heterozygous mutations: c.2909G>A (chr7: 117246728), c.*133T>A (chr7: 117307295) and c. *125delT (chr7: 117307285). The other patient was a 7-year-old boy with a history of recurrent respiratory infections.His parents were close relatives.Multiple cultures of sputum and bronchoalveolar lavage fluid of the boy were Pseudomonas aeruginosa, and chest CT suggested dilation and inflammation in bronchi of both lungs.Gene detection showed that the c. 380T>G homozygous mutation at chromosome chr7-117171059 resulted in an amino acid change p. leu127stop (nonsense mutation). This article suggests that CF should be considered for Pseudomonas aeruginosa infected children having signs of bronchiectasis on chest CT and a large number of secretions under bronchoscopy.Besides, it is necessary for such kind of children to perform genetic testing in time to confirm the diagnosis as soon as possible.

ABSTRACT

Drug use during pregnancy is unavoidable. Therefore, it is vitally important for medical workers to help pregnant women take drugs correctly to reduce the incidence of spontaneous abortion, premature birth, and low birth weight. In our study, drug screening model with induced pluripotent stem cells (iPSCs) was used to find some improper drugs which will result in woman's abortion. With 3D culture in vitro, iPSCs can form embryoid bodies (EBs) and cerebral organoids, which simulated in vitro development of early embryos, from inner cell mass to germ-layer differentiation. In the experiment, EBs were exposed to mifepristone (RU486), and three experimental groups were divided randomly. They were control group (without RU486), low-dose group (L-RU486, 10 μg·mL-1), and high-dose group (H-RU486, 20 μg·mL-1). After mifepristone exposure, EBs were observed at days 5, 8, and 11, including size of EB, cell apoptosis, and differentiation of germ layers, by using inverted optical microscope, TUNEL assay, and immunofluorescent staining. The results showed that through 3D culture, iPSCs could develop into embryoid bodies, neural rosettes, and finally cerebral organoids. After mifepristone exposure, EBs' sizes were decreased (P < 0.01); the levels of cell apoptosis in EBs were increased after mifepristone exposure (P < 0.01); the development of EBs' germ layer was affected. Mifepristone exposure could inhibit the proliferation of embryonic stem cells, reduce the differentiation of ectoderm (P < 0.01) and promote the development of mesoderm (P < 0.05). In conclusion, iPSCs can be used as a screening model for abortion drug, and EBs’ diameter, cell apoptosis, and differentiation changes of the germ layers can serve as criteria of abortion drug screening.

ABSTRACT

italic>Bulbophyllum orchids are popular for its ornamental appearance and great medicinal values. However, there is still a lack of research on phylogenetic relationship and species identification for this genus. In this study, the plastome sequences of three medicinal Bulbophyllum orchids (Bulbophyllum affine, Bulbophyllum pectinatum, Bulbophyllum funingense) were sequenced and analyzed. After assembly and annotation, it was found that the plastomes of Bulbophyllum plants encoded a total of 108 genes, including 74 protein-coding genes, 30 tRNA genes and 4 rRNA genes. Based on the analysis of mVISTA and comparison between junctions, it was found that the plastome structure of Bulbophyllum orchids was relatively conserved, and the variation mainly existed in the non-coding regions. Phylogenetic analysis showed that Bulbophyllum orchids were closely related to Dendrobium orchids. SSR analysis of Bulbophyllum showed that most SSRs were located in the intergenic spacer and had the most single nucleotide repeats. In addition, based on the comparative analysis of non-coding sequences, a total of 10 high-variability sequences were screened out, among which the combination of five non-coding region sequences, including psbI-trnS, psbC-trnS, clpP-ex1-psbB, psaJ-rpl33, rpl33-rps18, had the highest sequence variability and could be used in the species identification study of medicinal plants of Bulbophyllum. In conclusion, this study provides a theoretical basis for phylogenetic relationship and species identification of Bulbophyllum orchids through the comparative analysis of plastome sequences of three medicinal plants of the genus Bulbophyllum.

ABSTRACT

Aim To estimate the inhibition of curcumin derivative C1209 on the proliferation of chronic myeloid leukemia (CML) cells involving the disruption Hsp90 chaperon function. Methods The fluorescence spec-trum experiment was applied to examine the affinity be-tween different C1209 concentrations and Hsp90, NH-sp90,MHsp90,CHsp90;fluorescence intensities were recorded in the range of 290~510 nm at 293 K,303 K and 310 K,respectively;a colorimetric assay for in-organic phosphate based on the formation of a phospho-molybdate complex and subsequent reaction with mala-chite green was used to examine the inhibitory effects of C1209 on the activity of Hsp90 ATPase. MTT assay and CFSE were used for K562 and K562/G01cell pro-liferation determination in vitro by C1209. Western blot was used to detect the client proteins and the mo-lecular chaperone of Hsp90 level. Results The disso-ciation constant KDvalues of C1209 was (14.733 ± 0.713) μmol·L-1. The interaction between C1209 and Hsp90 was driven mainly by electrostatic interac-tion. C1209 showed the strongest affinity with CHsp90. When the concentration of ATP was 1mmol· L-1,the inhibition of Hsp90 ATPase activity of C1209 with the IC50value was 11.4 μmol·L-1; C1209 showed inhibition of K562 and K562/G01cells in dose-dependent proliferation and the IC50value was 1.14 μmol·L-1and 0.56 μmol·L-1, respectively after 24 h incubation. C1209 affected the molecular chaper-one functions of Hsp90 and down-regulated Bcr-Abl, Akt, MEK, ERK, c-Raf, p-Akt, p-MEK and p-ERK protein levels which were client proteins of Hsp90 in K562 and K562/G01cells. Conclusions Curcumin derivative C1209 is Hsp90 inhibitor;C1209 has signif-icant inhibitory effects on proliferation of K562 and K562 / G01, which may be related to C1209 affecting the molecular chaperone functions of Hsp90 and down-regulating client proteins of Hsp90 level.
