Laboratory Monitoring of Non-Vitamin K Antagonist Oral Anticoagulants and Their Use in Special Populations / 中山大学学报(医学科学版)

In the past few decades， heparin and warfarin have been the main anticoagulants used to treat and prevent venous thromboembolism. Recent studies at home and abroad have shown that non-vitamin K antagonist oral anticoagulants （NOACs） have similar or better efficacy and safety in the prevention and treatment of venous thromboembolism and non-valvular atrial fibrillation. NOACs do not require routine coagulation monitoring when used at a fixed dose. However， in special populations or specific scenarios such as emergency surgery， etc.， an overdose or underdose and abnormal metabolism of NOACs may reduce the drug efficacy and safety， so monitoring and evaluating the anticoagulant effect of NOACs is more conducive to the prognosis of patients.This paper briefly reviewed the common laboratory monitoring methods of NOACs and their use in special populations， aiming to explain different monitoring methods for different NOACs and the applicability of NOACs in special populations， and hoping to provide reference for clinical standard monitoring and use of NOACS.

Impact of Interleukin-10 Gene Polymorphisms on Survival in Patients with Colorectal Cancer

Chronic inflammation is thought to be the leading cause of colorectal cancer, and interleukin-10 (IL10) has been identified as a potent immunomodulatory cytokine that regulates inflammatory responses in the gastrointestinal tract. Although several single nucleotide polymorphisms (SNPs) in IL10 have been associated with the risk of colorectal cancer, their prognostic significance has not been determined. Two hundred and eighty-two colorectal cancer patients were genotyped for two candidate cancer-associated SNPs in IL10. The associations of these SNPs with distant metastasis-free survival and overall survival were evaluated by Kaplan-Meier analysis and Cox regression model. The minor homozygote GG genotype of IL10 rs3021094 was significantly associated with a 3.30-fold higher risk of death compared with the TT+TG genotypes (P=0.011). The patients with IL10 rs3021094 GG genotype also had a poorer overall survival in Kaplan-Meier analysis (log-rank P=0.007) and in multivariate Cox regression model (P=0.044) adjusting for age, gender, carcinoembryonic antigen levels, tumor differentiation, stage, lymphovascular invasion, and perineural invasion. In conclusion, our results suggest that IL10 rs3021094 might be a valuable prognostic biomarker for colorectal cancer patients.

An increased ratio of Th2/Treg cells in patients with moderate to severe asthma / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Recent studies have shown that T helper type-2 (Th2) cells can induce the apoptosis of CD4+CD25+ Treg cells or resist the immunosuppressive effect of Treg cells. We hypothesize that an imbalance of Th2/Treg is present in patients with allergic asthma.</p><p><b>METHODS</b>Twenty-two patients with mild asthma, 17 patients with moderate to severe asthma, and 20 healthy donors were enrolled. All patients were allergic to house dust mites. The proportion of peripheral blood CD4+CD25+ Treg cells and Th2 cells were determined by flow cytometry. The concentration of interleukin (IL)-10, transforming growth factor (TGF)-β and IL-4 in plasma was determined by enzyme linked immunosorbent assay. In these subjects, peripheral blood mononuclear cells from 17 mild asthmatic patients, 13 moderate to severe asthmatic patients and 14 healthy donors were acquired and expression of forkhead box P3 (Foxp3) and GATA-3 mRNA was detected by reverse-transcriptase polymerase chain reaction.</p><p><b>RESULTS</b>Compared with healthy donors and patients with mild asthma, the percent of CD4+CD25+ Treg cells and plasma IL-10 levels were decreased in patients with moderate to severe asthma. There were no significant differences in Foxp3 mRNA expression among three groups, but a downward trend seen among patients with asthma. However, the percent of Th2 cells, IL-4 levels and expression of GATA-3 mRNA was markedly higher in patients with mild and moderate to severe asthma than in the control group. The ratio of Th2/Treg and their cytokines was increased in allergic asthma, especially for moderate to severe asthma. The ratio of GATA-3/Foxp3 mRNA was also increased in allergic asthma. In patients with moderate to severe asthma, the percentage of peripheral blood Treg cells was negatively correlated to the percentage of Th2 cells and IL-4 levels.</p><p><b>CONCLUSIONS</b>The decline of CD4+CD25+ Treg cells in patients with moderate to severe asthma may play an important role in progress of the disease. Furthermore, the deficiency of CD4+CD25+ Treg cells was associated with the over-expression of Th2 response.</p>

Effects of smoking and alcohol drinking on arsenic metabolism of people exposed to different concentrations of arsenic in drinking water / 中国地方病学杂志

Objective To explore the effects of smoking and alcohol drinking on arsenic metabolism of people exposed to different concentrations of arsenic in drinking water.Methods Residents in Shanxi exposed to different concentrations of arsenic in drinking water and age ≥ 18 years old adults were chosen as the subjects for this study in 2008,the subjects were divided into three groups according to the concentrations of arsenic in drinking water: high-arsenic exposure group (more than 0.05 mg/L),low-arsenic exposure group (between 0.01 and 0.05 mg/L) and control group(less than 0.01 mg/L),excluded recently had eaten seafood and had poisoning symptoms of chronic arsenic in drinking water in the crowd.Smoking and alcohol drinking habits were investigated by questionnaire.Arsenic species in the urine samples were detected with hydride generation atomic absorption spectroscopy.Total arsenic(tAs) was the sum of iAs％,MMA％ and DMA％.iAs％,MMA％ and DMA％ were calculated as iAs/tAs,MMA/tAs and DMA/tAs,respectively.The first methylation ratio(FMR) and the secondary methylation ratio(SMR) were calculated as (MMA + DMA)/tAs and DMA/(MMA + DMA),respectively.Results Three hundred and ninety-five adults were chosen in this study.In the high exposure group the alcohol drinking and smoking subjects had higher MMA％(16.24％) but lower SMR(82.19％ ) than the non-drinking and non-smoking subjects (12.16％ and 86.13％,respectively).The differences of both MMA％ and SMR were significant(P ＜ 0.05 ).No significant difference was observed between the non-smoking/non-drinking subjects and the smoking or the drinking subjects(all P ＞ 0.05 ).In the low exposure group there were higher MMA％( 13.86％,13.99％) lower DMA％(72.87％,77.76％)and lower SMR (83.48％,83.90％ ) in those with smoking or drinking/smoking compared with the non-drinking and non-smoking subjects (11.83％,80.35％ and 86.54％,respectively,all P ＜0.05 ).No significant difference was observed between drinkers and non-drinking/non-smoking subjects(P ＞ 0.05).In the control group there were a higher MMA％( 17.27％,17.06％) lower DMA％ (73.89％,72.29％) and lower SMR (81.48％,82.58％ ) in those with smoking or drinking/smoking compared with the non-drinking and nonsmoking subjects( 11.52％,79.68％ and 87.19％,respectively,all P ＜ 0.05).No significant difference was observed between drinkers and the non-drinking/non-smoking subjects (all P ＞ 0.05).ConclusionThe arsenic methylation capacity of people with drinking and smoking is poorer than that of non-drinking and non-smoking subjects after arsenic exposure.

ObjectiveTo construct geographic information database of drinking water type of endemic arsenism at village level with Google Earth and provide scientific basis for prevention and management of endemic arsenism.MethodsDrinking water samples were collected in the field of Shilegetu village,Tuoketuo county,Inner Mongolia in 2008.Arsenic concentrations were determined by high-performance liquid chromatography-hydride generation-atomic fluorescence spectrometry.Global positioning system(GPS) was performed to obtain the geographic information of the water sources.Google Earth was applied to establish the geographic information database.Results There were 5 drinking water resources in this village.They were located between 40°29′09″ N and 40°29′36″ Nlatitude and 111°28′00″ E and 111°29′02″ E longitude,with the altitude between 1010 m and 1021 m.For all drinking water resources,four water arsenic concentrations was beyond 0.05 mg/L and one below 0.05 mg/L.In addition,one water source had been abandoned and the remaining four were providing daily drinking water for residents of the villages.ConclusionsThe geographic information database,established by Google Earth,can intuitively reflect the real situation of the endemic village.It can provide more useful information for field epidemiological research.It is an effectively tool in control and management of endemic arsenism.

Coexistence of Th1/Th2 and Th17/Treg imbalances in patients with allergic asthma / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Recent recognition is that Th2 response is insufficient to fully explain the aetiology of asthma. Other CD4(+) T cells subsets might play a role in asthma. We investigated the relative abundance and activities of Th1, Th2, Th17 and CD4(+)CD25(+) Treg cells in patients with allergic asthma.</p><p><b>METHODS</b>Twenty-two patients with mild asthma, 17 patients with moderate to severe asthma and 20 healthy donors were enrolled. All patients were allergic to house dust mites. Plasma total IgE, pulmonary function and Asthma Control Questionnaire were assessed. The proportions of peripheral blood Th1, Th2, Th17 and CD4(+)CD25(+) Treg cells were determined by flow cytometry. The expression of cytokines in plasma and in the culture supernatant of peripheral blood mononuclear cells was determined by enzyme linked, immunosorbent assay.</p><p><b>RESULTS</b>The frequency of blood Th2 cells and IL-4 levels in plasma and culture supernatant of peripheral blood mononuclear cells were increased in all patients with allergic asthma. The frequency of Th17 cells and the plasma and culture supernatant levels of IL-17 were increased, whereas the frequency of CD4(+)CD25(+) Treg cells and plasma IL-10 levels were decreased in patients with moderate to severe asthma. Dermatophagoides pteronyssinus specific IgE levels were positively correlated with the percentage of blood Th2 cells and plasma IL-4 levels. Forced expiratory volume in the first second was negatively correlated with the frequency of Th17 cells and plasma IL-17 levels, and positively correlated with the frequency of Treg cells. However, mean Asthma Control Questionnaire scores were positively correlated with the frequency of Th17 cells and plasma IL-17 levels, and negatively correlated with the frequency of Treg cells.</p><p><b>CONCLUSIONS</b>Imbalances in Th1/Th2 and Th17/Treg were found in patients with allergic asthma. Furthermore, elevated Th17 cell responses, the absence of Tregs and an imbalance in Th17/Treg levels were associated with moderate to severe asthma.</p>

Fluorine-fixing efficiency on calcium-based briquette: pilot experiment, demonstration and promotion / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>The fluorosis derived from coal burning is a very serious problem in China. By using fluorine-fixing technology during coal burning we are able to reduce the release of fluorides in coal at the source in order to reduce pollution to the surrounding environment by coal burning pollutants as well as decrease the intake and accumulating amounts of fluorine in the human body. The aim of this study was to conduct a pilot experiment on calcium-based fluorine-fixing material efficiency during coal burning to demonstrate and promote the technology based on laboratory research.</p><p><b>METHODS</b>A proper amount of calcium-based fluorine sorbent was added into high-fluorine coal to form briquettes so that the fluorine in high-fluorine coal can be fixed in coal slag and its release into atmosphere reduced. We determined figures on various components in briquettes and fluorine in coal slag as well as the concentrations of indoor air pollutants, including fluoride, sulfur dioxide and respirable particulate matter (RPM), and evaluated the fluorine-fixing efficiency of calcium-based fluorine sorbents and the levels of indoor air pollutants.</p><p><b>RESULTS</b>Pilot experiments on fluorine-fixing efficiency during coal burning as well as its demonstration and promotion were carried out separately in Guiding and Longli Counties of Guizhou Province, two areas with coal burning fluorosis problems. If the calcium-based fluorine sorbent mixed coal was made into honeycomb briquettes the average fluorine-fixing ratio in the pilot experiment was 71.8%. If the burning calcium-based fluorine-fixing bitumite was made into a coalball, the average of fluorine-fixing ratio was 77.3%. The concentration of fluoride, sulfur dioxide and PM10 of indoor air were decreased significantly. There was a 10% increase in the cost of briquettes due to the addition of calcium-based fluorine sorbent.</p><p><b>CONCLUSIONS</b>The preparation process of calcium-based fluorine-fixing briquette is simple yet highly flammable and it is applicable to regions with abundant bitumite coal. As a small scale application, villagers may make fluorine-fixing coalballs or briquettes by themselves, achieving the optimum fluorine-fixing efficiency and reducing indoor air pollutants providing environmental and social benefits.</p>

The cupping mark color at each site was assessed 24 hours after cupping with a cupping mark color atlas, and the change law of cupping mark color was analyzed.</p><p><b>RESULTS</b>There was a significant difference for the different parameters (P < 0.01). The time factor had statistically significant effect on cupping mark color (P < 0.05), showing 10 min >30 min >20 min. The effect of pressure factor on cupping mark color was significant (P < 0.01), showing -0.07 MPa > -0.06 MPa > -0.05 MPa > -0.04 MPa.</p><p><b>CONCLUSION</b>The stimulation of 10 minutes and the pressure of -0.04 MPa produces a marked ecchymosis on the cupping site, getting darker and darker along with increase of the stimulation intensity; the effect of pressure factor on cupping mark color is the largest with a linear relationship, which can be expressed as Y (cupping skin color) = 2.025 + 0.902 x 100 x negative pressure absolute value (-MPa); while the effect of time factor on cupping mark color is more complicated, which is possibly related with the cupping site.</p>

Risk factors related to hospital mortality in patients with isolated traumatic acute subdural haematoma: analysis of 308 patients undergone surgery / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Acute subdural haematoma (ASDH) is a common traumatic brain injury with a relatively high mortality rate. However, few studies have examined the factors predicting the outcome of isolated traumatic ASDH. This clinical study examined the hospital mortality and analyzed the risk factors for mortality in patients treated surgically for isolated traumatic ASDH.</p><p><b>METHODS</b>We collected 308 consecutive patients who underwent neurosurgery for isolated traumatic ASDH between January 1999 and December 2007 and used multivariate Logistic regression analysis to evaluate the influence of 11 clinical variables on hospital mortality.</p><p><b>RESULTS</b>The overall hospital mortality was 21.75% (67/308). Age (OR = 1.807), preoperative Glasgow Coma Score (OR = 0.316), brain herniation (OR = 2.181) and the time from trauma to decompression (OR = 1.815) were independent predictors of death, while no independent association was observed between hospital mortality and haematoma volume, midline shift, acute brain swelling or brain herniation duration, although these variables were correlated with hospital mortality in univariate analyses.</p><p><b>CONCLUSIONS</b>This study identified the risk factors for hospital mortality in patients who underwent surgical treatment for isolated traumatic ASDH. An increased risk of death occurs in patients who are over 50 years of age and have lower preoperative Glasgow Coma Scores, the presence of brain herniation and a long interval between trauma and decompression. The findings should help clinicians determine management criteria and improve survival.</p>

Rats, except that in the normal group, were subcutaneously administered danazol 300 micrograms at 5 days of age individually and CHM was fed to rats in the CHM group from 15 days of age, in the meantime, normal saline was fed to rats in the blank control group. Expression of GnRH in hypothalamus was observed by immunohistochemical method and expressions of GnRH mRNA in hypothalamus and GnRH receptor mRNA in pituitary were determined by RT-PCR.</p><p><b>RESULTS</b>Compared with rats in the normal groups, the vaginal opening and the onset of first estrus were ahead of time, the number of GnRH immunoreactive positive cells decreased and the expressions of GnRH mRNA in hypothalamus and GnRH receptor mRNA in pituitary up-regulated in the model rats and blank control rats. Compared with the model and the blank control groups, in CHM group, all the above-mentioned abnormally changed parameters improved significantly after treatment.</p><p><b>CONCLUSION</b>CHM for nourishing Yin and purging Fire may inhibit the abnormal hyperfunction of hypothalamus-pituitary-ovary axis in precocious puberty rat induced by danazol via reducing the synthesis and release of GnRH, and lowering the responsibility of pituitary cells to GnRH. This may be the primary mechanism of CHM in effectively treating the true precocious puberty.</p>
