ABSTRACT
Objective:To explore the correlation between Traditional Chinese Medicine (TCM) syndrome types of Sj?gren syndrome (SS) and blood test parameters, immunological function and disease activity.Methods:A retrospective cross-sectional study was conducted. The clinical data of 242 SS inpatients in the Rheumatology and Immunology Department of Jiangsu Province Hospital of TCM from February 2021 to June 2022 were analyzed retrospectively. We compared the general data (gender, age, course of disease, BMI), blood parameters [WBC, hemoglobin (Hb), PLT, neutrophil count (NEUT), lymphocyte count(LYMPH), neutrophil/lymphocyte ratio (NLR)], immunological indicators (globulin, IgG, IgA, IgM, rheumatoid factor (RF), anti-SSA antibody, anti-SSB antibody, anti-Ro-52 antibody) .The distribution difference of disease activity [Disease Activity Index of Sjogren's syndrome (ESSDAI) and Patient Report Index of Sjogren's syndrome (ESSPRI)], the correlation between each syndrome type and blood routine parameters, immunological indicators and inflammatory indicators was analyzed by binary logistic regression.Results:They were divided into 82 cases of qi yin deficiency syndrome, 61 cases of yin deficiency and fluid deficiency syndrome, 59 cases of yin deficiency and blood stasis syndrome, 32 cases of yin deficiency and heat toxin syndrome, and 8 cases of other syndrome types. Because the number of other syndrome types was small, they were not included in this study. Logistic regression analysis showed that the positive rate of anti SSA antibody was negatively correlated with IgM [ OR (95% CI)=0.570 (0.407, 0.798)] ( P<0.01). The positive rates of anti SSB antibody and anti Ro-52 antibody were negatively correlated with LYMPH [ OR (95% CI)=0.445 (0.223, 0.886), 0.457 (0.224, 0.932), respectively] ( P<0.05). The positive rates of anti SSB antibody and anti Ro-52 antibody were positively correlated with IgG [ OR (95% CI)=1.171 (1.034, 1.325), 1.159 (1.014, 1.325), respectively] ( P<0.05). Qi Yin deficiency syndrome was positively correlated with WBC [ OR (95% CI)=2.590 (1.120, 5.987)] ( P<0.05), and negatively correlated with LYMPH [ OR (95% CI)=0.090 (0.017, 0.470)] and IgA [ OR (95% CI)=0.728 (0.553, 0.959)] ( P<0.05). Yin deficiency and fluid deficiency syndrome were negatively correlated with PLT [ OR (95% CI)=0.991 (0.984, 0.998)], ESSPRI [ OR (95% CI)=0.705 (0.506, 0.983)], ESSDAI [ OR (95% CI)=0.716 (0.534, 0.960)] ( P<0.05). Yin deficiency and blood stasis syndrome was positively correlated with IgA [ OR (95% CI)=1.184 (1.028, 1.363)] ( P<0.05), and negatively correlated with anti SSB antibody positive rate [ OR (95% CI)=0.247 (0.093, 0.659)] ( P<0.05). Yin deficiency heat toxin syndrome was positively correlated with IgA [ OR (95% CI)=1.368 (1.037, 1.803)] ( P<0.05), and negatively correlated with anti SSB antibody positive rate [ OR (95% CI)=0.278 (0.085, 0.909)] ( P<0.05). Conclusion:The level of immunoglobulin, inflammatory index and disease activity of yin deficiency and blood stasis syndrome and yin deficiency and heat toxin syndrome are high, and blood system damage and exocrine gland disease are easy to occur, which can provide clinical basis for the combination of disease and syndrome differentiation and treatment of SS.
ABSTRACT
ObjectiveTo explore the clinical effect of kidney-tonifying and blood-generating method and qi-promoting and blood-nourishing method combined with western medicine on the treatment of aplastic anemia and the characteristics of blood routine recovery， and to explore a new phased treatment model for aplastic anemia. MethodThis study was based on a prospective， multicenter， double-blind， and randomized controlled clinical trial. Patients with aplastic anemia from 19 centers were analyzed and divided into a kidney-tonifying and blood-generating group and a Qi-promoting and blood-nourishing group， which were treated with traditional Chinese medicine （TCM） combined with western medicine. The clinical effect and the changes in blood routine in each group during treatment were evaluated. ResultDuring the observation period， 375 cases of aplastic anemia were included in two groups， and TCM syndrome differentiation conformed these cases as Qi-deficiency type and both Qi and blood-deficiency type. These cases were randomly divided into two groups， including 184 in the kidney-tonifying and blood-generating group and 191 in the Qi-promoting and blood-nourishing group， being treated by kidney-tonifying and blood-generating granules and Qi-promoting and blood-nourishing granules， respectively， and combined oral androgen and ciclosporin soft capsules. The treatment lasted for six months and was divided into three stages. Visits were conducted from the beginning of the treatment to the end of the first， fourth， and sixth months. The curative effect was evaluated six months later. The total effective rate of the kidney-tonifying and blood-generating group was 86.4% （159/184）， which was significantly better than that of the Qi-promoting and blood-nourishing group ［68.6% （131/191）， P<0.01）］. The results of the percentage quartile of blood cell growth in each stage of the 2 groups were analyzed. The hemoglobin concentration and platelet count of the patients in the kidney-invigorating blood group continued to increase after treatment, and significantly increased in the second and third stages compared with the first stage (P<0.05). The increase of reticulocyte count was most significant in the first stage of treatment (P<0.05). The reticulocyte count in supplementing Qi and nourishing blood group increased significantly in the first and second stages of treatment (P<0.05). The other observation indicators increased at each stage, but there was no statistical difference in the growth rate. The effects of the two groups were compared by stages. In the second stage of treatment, the increase of hemoglobin concentration in the kidney-invigorating blood group was better than that in the supplementing Qi-nourishing blood group (P<0.05). The increase of platelet count and red blood cell count in supplementing Qi and nourishing blood group was greater (P<0.05). In the third stage of treatment, the increase of hemoglobin concentration in the bushen Shengxue group was more significant (P<0.05). ConclusionThe overall effective rate of the kidney-tonifying and blood-generating method in the treatment of aplastic anemia is better than that of the Qi-promoting and blood-nourishing method， with significant effects and safety. This study has proposed a three-stage early treatment mode for aplastic anemia. The first and third stages (0-1, 5-6 months) were mainly treated by invigorating kidney and generating blood. In the second stage of treatment (2-4 months), invigorating kidney and generating blood combined with invigorating Qi and nourishing blood were adopted. It may be closer to the actual clinical treatment response and objective rule changes of aplastic anemia.
ABSTRACT
ObjectiveTo investigate the patterns of changes in routine blood parameters， thyroid hormone levels， and their correlations with thyroid peroxidase antibodies （TPOAb） among women at different stages of pregnancy， so as to provide a theoretical basis for maternal and child health care and diagnosis and treatment. MethodsA total of 732 pregnant women at different stages of pregnancy who underwent health examinations at the First Maternity and Infant Hospital affiliated to Tongji University from May 2020 to August 2022 were selected as the observation group. The group comprised 245 women in the first trimester （≤12 weeks）， 247 women in the second trimester （between13 and 27 weeks） and 240 women in the third trimester （≥28 weeks）. Additionally， 240 non-pregnant， healthy women of child-bearing age who conducted their health checkups in the same hospital were selected as the control group. All the research subjects were required to provide peripheral venous blood samples to measure hemoglobin （Hb）， standard deviation of red blood cell distribution width （RDW-SD）， coefficient of variation of red blood cell distribution width （RDW-CV）， platelet （Plt） count， platelet distribution width （PDW）， as well as thyroid stimulating hormone （TSH）， total thyroxine （TT4）， total triiodothyronine （TT3）， free thyroxine （FT4）， free triiodothyronine （FT3）， and TPOAb. The results were statistically analyzed. ResultsWith advancing gestational age， Hb levels were significantly lower in the second and third trimesters than in the first trimester and the control group （F=68.25， P<0.001）， while RDW-SD and RDW-CV were significantly higher （F=41.34， P<0.001； F=3.64， P=0.012）. Plt levels throughout pregnancy were significantly lower than that in the control group （F=43.21， P<0.001）. TSH levels were significantly lower in the first and second trimesters than in the control group （Z=53.49， P<0.001）， but gradually increased with gestational age. TT3 and TT4 levels were significantly higher than those in the control group throughout pregnancy （F＝148.25， P<0.001； F＝210.83， P<0.001）， while FT3 and FT4 levels were significantly lower in the second and third trimesters than in the first trimester and the control group （F=42.95， P<0.001； F=101.73， P<0.001）. The abnormal rate of TPOAb was significantly higher than that in the control group throughout pregnancy （χ2＝25.61， P<0.001）. Among pregnant women， those with TPOAb positivity had significantly higher TSH levels and RDW-CV than those with TPOAb negativity （Z＝5.70， P<0.001； t＝2.39， P＝0.018）. ConclusionThe levels of Hb， Plt， and thyroid hormones in pregnant women are closely related to gestational age. With increasing gestational age， the abnormal rate of TPOAb decreases， but the TSH levels and RDW-CV of TPOAb positive pregnant women are higher， requiring clinical attention and screening to improve maternal and child health.

Objective:To analyze the early clinical features of children with coronavirus disease 2019 (COVID-19) in order to further improve the understanding of the disease.Methods:A total of 312 children with COVID-19 under 16 years old who were first diagnosed in the children′s fever clinic at Xinhua Hospital Affiliated to Shanghai Jiaotong University School of Medicine from March to May 2022 were retrospectively analyzed.The epidemiology, early clinical features and blood routine results of children were described, and the blood routine results among different age groups were compared.Results:The median age of 312 children was 3.15(1.47, 6.51) years.The proportion of infection rate of children with different ages from high to low were 1~3 years old, > 6 years old, 3~6 years old and ≤ 1 year old.Only 17 (5.4%) cases had underlying diseases.Additionally, 70.2% patients had definite positive case reports in their residential communities, and 65.1% showed a familial cluster.Moreover, 96.2% patients had fever and 52.9% patients had respiratory symptoms.The main symptoms are fever (96.2%), cough (38.1%), runny nose (20.2%), vomiting (14.7%), sore throat (11.5%), poor appetite (6.7%), nasal congestion (4.5%), expectoration (4.5%), convulsion (4.2%), diarrhea (3.8%), etc.Among 309 children, 11.3% patients had increased white blood cell count, especially in children over 6 years old ( P=0.006); 31.7% patients had decreased lymphocyte count and 32.4% had increased C-reactive protein.The positive rate of point-of-care testing was as high as 99%. Conclusion:Children with COVID-19 in Shanghai had the characteristics of familial cluster.The main symptoms are fever and respiratory symptoms.Most of the blood routine leukocytes have no obvious changes, and a few have lymphopenia and C-reactive protein elevation.Point-of-care testing detection can help the children′s fever clinic to early screen COVID-19.
ABSTRACT
Background As an environmental pollutant, 1-bromopropane (1-BP) is ubiquitous in the living environment. However, its health effects on the general population are still unclear. Objective To assess the associations between urinary 1-BP metabolite and blood routine indices in a Chinese community population. Methods A total of 3512 community residents aged 18-80 years from the baseline of the Wuhan-Zhuhai cohort were included in our study. The demographic characteristics, disease history, and lifestyles of the participants were collected through questionnaires. Height, weight, blood pressure, and other anthropometrics were collected through physical examination. Blood routine indicators were tested using an automated hematology analyzer. Urinary 1-BP metabolite N-Acetyl-S-(n-propyl)-L-cysteine (BPMA) was measured by ultra-high-performance liquid chromatography coupled with electrospray ionization tandem mass spectrometry. Generalized linear models and logistic regression models were used to assess the associations of urinary BPMA with blood routine indices and the risks of abnormal blood routine indices, respectively. Besides, stratified analysis and effect modification analysis were further conducted to investigate the effects of individual characteristics and lifestyles on the associations of urinary BPMA with blood routine indices. All models were adjusted for gender, age, and other potential confounders. Results The mean age of the study population (30.1% male) was (52.78±12.77) years. The median (P25, P75) level of urinary BPMA adjusted for urinary creatinine was 0.90 (0.50, 1.73) mg·mol−1. In the analysis with target indicator as continuous variable, each 1-unit increase in natural logarithm-transformed urinary BMPA level was associated with a 0.078×109 L−1, 0.031×109 L−1, 0.307%, 3.518 g·L−1, and 2.469×109 L−1 decrease in white blood cell, lymphocyte, lymphocyte percentage, mean corpuscular hemoglobin concentration, and platelet levels, respectively (all Ps<0.05); and with a 0.440%, 1.140 fL, 0.014 fL, and 0.020 increase in hematocrit, mean corpuscular volume, and natural logarithm-transformed levels of mean platelet volume and mean platelet volume/platelet, respectively (all Ps<0.05). The categorical analysis across quartiles of BPMA level showed that BPMA was inversely associated with lymphocyte percentage, mean corpuscular hemoglobin concentration, and platelet levels in a dose-dependent manner (all Ptrend<0.05), and positively related to hematocrit, mean corpuscular volume, mean platelet volume, and mean platelet volume/platelet levels in a dose-dependent manner (all Ptrend<0.05). Body mass index, smoking, and drinking modified the associations of urinary BPMA level with red blood cell, mean corpuscular hemoglobin concentration lymphocyte percentage, and hemoglobin (all Ps<0.05). In addition, urinary BPMA was associated with an increased risk of abnormal increase in mean corpuscular volume (OR=1.316, 95%CI: 1.171-1.478) and red blood cell volume distribution width (OR=1.255, 95%CI: 1.030-1.528), and abnormal decrease in mean corpuscular hemoglobin concentration (OR=1.200, 95%CI: 1.035-1.392). Conclusion Exposure to 1-BP of the general population is associated with decreased white blood cells and platelets, as well as abnormal change of blood cell morphology or function.
ABSTRACT
【Objective】 To study the changes of blood coagulation function of donors before and after peripheral blood stem cell(PBSC)mobilization and collection, so as to evaluate the safety of the current scheme. 【Methods】 30 donors who received PBSC mobilization and collection in Zhujiang Hospital from October 2018 to October 2020 were enrolled. After mobilization by G-CSF, the correlation between coagulation function, blood routine indexes and TEG indexes of donors was analyzed, and the influence of PBSC mobilization and collection on coagulation function of donors was evaluated. 【Results】 The TEG indexes R(min), K(min), α(°), MA(mm) and CI before and after PBSC collection were 6.12±1.18 vs 7.25±2.16, 1.98±0.41 vs 2.45±0.64, 62.82±4.98 vs 57.3±6.67, 60.93±3.26 vs 55.37±4.41, and -0.31±1.40 vs -2.32±2.18, respectively(P<0.05), suggesting that there was no risk of hypercoagulability after PBSC mobilization and collection. The peak values of WBC (×109/L), Plt (×109/L) and Hb (g/L) were 62.02, 357 and 162, respectively, which indicated that the blood routine indexes after PBSC mobilization and collection were in the safe range. After PBSC collection, the CI value of 26.7% (8/30) donors was less than -3, showing hypocoagulability. 【Conclusion】 The current mobilization and collection scheme of PBSC has little effect on the coagulation function. Most of the donors had no risk of hypercoagulability, but a few showed a trend of hypocoagulability after PBSC collection.
ABSTRACT
Objective:To analyze the clinical features of adult patients with extremely elevated erythrocyte sedimentation rate (ESR, ESR≥100 mm/1 h), so as improve the ability of clinicians to use erythrocyte sedimentation rate to assist in the diagnosis and treatment of diseases.Methods:A retrospective cohort study was conducted to examine the clinical data of patients with ESR ≥ 100 mm/1 h admitted to the First Affiliated Hospital of Kunming Medical University from January 1st 2019 to December 31st 2019. The age, gender, clinical diagnosis, first ESR level after admission, blood routine, liver function, renal function, coagulation function and C-reactive protein (CRP) within 24 hours after admission were collected. Patient cohorts were divided into youth group (18-65 years old), middle-aged group (66-79 years old) and elderly group (≥80 years old) according to the new standards of human age classification of World Health Organization (WHO) 2019. Patient cohorts were also divided into infectious disease group, hematological disease group, autoimmune disease group, renal failure group and others according to their respective clinical diagnosis. The distribution of extremely elevated ESR in each group, and the correlation between ESR and various laboratory indicators were analyzed.Results:① Among 429 patients with ESR≥ 100 mm/1 h, there were 236 males and 193 females. There was no significant difference in ESR levels between males and females [mm/1 h: 108.00 (103.00, 119.75) vs. 117.00 (105.50, 140.00), P = 0.234]. ② The age of 429 patients ranged from 18 to 98 years old, the average age was (53.70±18.70) years old. There were 310 cases in the youth group, 87 cases in the middle-aged group and 32 cases in the elderly group. The ESR level of the young group was significantly lower than that of the middle-aged group and the elderly group [mm/1 h: 108.00 (103.00, 120.00) vs. 119.00 (107.00, 140.00), 120.00 (110.25, 140.00), both P < 0.01]. ③ The main diagnoses associated with extremely elevated ESR were infectious diseases [157 cases (36.6%)], hematological system diseases [127 cases (29.6%)], autoimmune diseases [74 cases (17.2%)]. Pulmonary infection accounted for 58.0% (91/157) of infectious diseases. Hematopoietic stem cell diseases accounted for 45.7% (58/127), lymphocyte and plasma cell diseases accounted for [37.0% (47/127)] and erythrocyte diseases accounted for [11.0% (14/127)] of the hematological system diseases. Diffuse connective tissue diseases accounted for 75.7% (56/74) of autoimmune diseases. ④ Spearman correlation analysis showed that the extremely elevated ESR in all patients was significantly negatively correlated with the levels of red blood cell count (RBC), hemoglobin (HB) and hematocrit (HCT) (ρvalue was -0.395, -0.381 and -0.383, respectively, all P < 0.01), the ESR was significantly positively correlated with the level of fibrinogen (FIB; ρ= 0.345, P < 0.01). A total of 266 patients were tested for both ESR and CRP, and there was no significantly correlation between ESR and CRP level (ρ= -0.019, P = 0.756). Conclusions:The extremely elevated ESR was more common in pulmonary infections diseases, hematopoietic stem cell diseases, lymphocyte and plasma cell diseases, erythrocyte diseases and diffuse connective tissue diseases. The extremely elevated ESR was significantly correlated with the levels of RBC, HB, HCT and FIB.
ABSTRACT
OBJECTIVE: To establish the laboratory historical control values for biological indicators in SD rats with 28-day repeated dose oral toxicity tests. METHODS: The body mass, blood routine indexes, serum biochemical indexes, organ mass and organ coefficient of 10 batches of specific pathogen free SD rats in the control group and the control additional group were collected for 28-day repeated dose oral toxicity tests, and the historical control values was established. RESULTS: The body mass of both male and female SD rats increased with the increasing age(all P<0.01). The body mass of male rats was higher than that of female rats each week(all P<0.01). The body mass, blood routine and serum biochemical indexes, organ mass and organ coefficient of SD rats were affected by the age and gender of rats to varying degrees. The effects of age and gender on organ mass and organ coefficient were not consistent. The laboratory historical control values of body mass, blood routine indexes, serum biochemical indexes, organ mass and organ coefficient of SD rats were established according to the age measured in weeks and the gender of rats. CONCLUSION: The laboratory control values of biological indicators of SD rats should be established according to different weekly age and the gender of rats. Organ coefficient is more suitable as an observation index for toxicological safety evaluation compared with organ mass.
ABSTRACT
【Objective】 To investigate the changes in peripheral blood routine in blood donors after multiple and frequent platelets donation. 【Methods】 A total of 228 voluntary blood donors who donated apheresis platelets for 5 or more times were selected. The results of peripheral blood routine testing before the first and most recent donation were collected. The data were analyzed in terms of blood donation volume, frequency of blood donation (total frequency/total months), and numbers of blood donation. 【Results】 1) There was statistical significance in the decrease of WBC counts when the accumulative volume of platelet donation >18 treatment doses and the number of blood donation >10 (P18, (P18 treatment doses, blood donation frequency ≥1, and the number of blood donation >18(P18 treatment doses (P0.05), and a significant lead in the Plt value of most recent donation was observed again until the blood donation volume reached ≥76 treatment doses (P1.4 and the number of blood donations≥40, the Plt value of the most recent donation was significantly higher than that of the first one(P18 treatment doses, blood donation frequency >1.4, and the number of donation >18, it is recommended to extend the donation interval and/or take iron supplements appropriately.
ABSTRACT
【Objective】 To explore the effects of blood routine parameters on the peripheral blood hematopoietic stem cell collection of healthy donors, and predict collection timing based on these parameters. 【Methods】 The blood routine parameters pre-donation and the total number of mononuclear cells post-donation of 249 donors who applied blood cell separator to collect peripheral blood hematopoietic stem cells in our hospital from January 2018 to August 2020 were collected. Taking total nucleated cells of circulating blood per litre as the main evaluation index, and its collection with blood routine parameters pre-collection was analyzed. The relevant influencing factors were analyzed using multiple linear regression analysis. The blood routine parameters of healthy donors who donated peripheral blood hematopoietic stem cells in our hospital from September 2020 to October 2020 were substituted into the equation to obtain the predicted values, which were then compared with the actual values obtained from actual product using t test for verification. 【Results】 The analysis showed that the parameters of Hb, RBC, Hct, leukocyte count, neutrophil, lymphocyte, monocyte and Plt were statistically correlated with the total number of mononuclear cells of circulating blood per liter volume (P<0.05). There was a linear relationship between lymphocyte, monocyte, Plt and leukocyte count and the total number of mononuclear cells of circulating blood per liter. The total number of mononuclear cells of circulating blood per liter was set to (Y), and the variables such as lymphocyte (X1), monocyte (X2), Plt (X3), leukocyte count (X), and neutrophil were used as dependent variables for multiple linear regression, and the equation was: Y=9.814+ 3.131X1+ 1.666X2+ 0.020X3+ 0.124X4. There was no statistical difference between the predicted value and the calculated value (P>0.05). 【Conclusion】 The blood routine parameters of lymphocyte, monocyte, platelet count and leukocyte count of donors before collection can effectively predict the collection efficiency, therefore help predict the collection time.
ABSTRACT
Objective To investigate the characteristics of blood routine in 129 patients with COVID-19, and analyze the correlation between blood routine parameter changes and clinical classification. Methods A total of 129 COVID-19 patients were recruited and their blood samples were collected at the beginning and the end of treatment.The neutrophil-to-lymphocyte ratio(NLR), platelet-to-lymphocyte ratio(PLR), lymphocyte-to-monocyte ratio(LMR) and C-reactive protein(CRP) were determined and used to calculate Δ NLR, Δ PLR, Δ LMR.The differences in these parameters were compared between the non-severe group (93 cases) and the severe group (36 cases).In addition, the relationship between the changes in blood routine test result and the prognosis of patients was determined. Results The average age of 129 patients was 46.9±17.4 years old, and the ratio of male to female was 1.2 ∶ 1.Thirty-five (35) cases (27.1%) had leucopenia (< 4×109/L) and 59 cases (45.7%) had lymphopenia (< 1.1×109/L).There were statistically significant differences in age, treatment days, blood routine indexes between these two groups.In all the patients, the differences between before and after treatment were statistically significant in the following: leukocyte number, neutrophil cell percentage, lymphocyte number, lymphocyte percentage, monocyte number, monocyte percentage.The differences in RBC, HGB, CRP, and NLR between the two groups before and after treatment were also statistically significant (P < 0.05). Conclusion The older COVID-19 patients have lower number of lymphocytes, higher NLR and PLR, lower LMR and higher CRP.They have a higher risk of progressing to severe disease.After treatment, there is an increase in the number of granulocytes, especially the number of lymphocytes, while a decrease in CRP and NLR.The change of lymphocyte count, NLR and CRP levels can predict the risk of severe COVID-19 and evaluate the therapeutic effect.
ABSTRACT
OBJECTIVE：To investigate the protective effect an d possible m echanism of Shenqi zhilong decoction （SZD） combined with Tripterygium polyglycoside tablets （TPT）on membranous nephropathy （MN）model rats. METHODS ：MN rat model was established by subcutaneous and caudal vein injecting cationic bovine serum albumin + incomplete Freund adjuvant emulsion for 6 weeks. At the 3rd week of modeling ，model rats were randomly divided into model control group ，SZD low-dose and high-dose groups （4，8 g/kg，by total crude drugs ），TPT group （9 mg/kg），low-dose and high-dose of SZD+TPT groups （same dose as single group ），with 10 rats in each group according to 24 h UTP and weight. Another 10 rats withoutmodeling were taken as blank control group. Blank control group was given equal amount of water intragastrically administration groups were given relevant medicine intragastrically，once a day ，for consecutive 4 weeks. The 24 h UTP of rats were detected one day before the last administration；1 h after the la st administration ，blood routine 中indexes（WBC，RBC，PLT），liver func tion indexes （TP，ALB，AST，ALT），blood lipid indexes （TC，TG，HDL-C，LDL-C）， the contents of glucose （GLU），urea nitrogen （BUN）and serum creatinine （Scr）were detected in each group. Uranyl acetate-lead citrate staining was used to observe ultrastructural changes of renal tissue. Immunohistochemical method was used to detect the protein expression of TGF-β1 and HPA- 1 in renal tissue. RESULTS ：Compared with blank control group ，in the model control group，the glomerular podocytes were widely fused or disappeared ，microvilli were formed ，basement membrane was heavily thickened，a large number of electron dense substance was deposited under the epithelium ，TGF-β1 and HPA- 1 positive cells were significantly increased ；24 h UTP ，PLT，the contents of TC ，TG and HDL-C ，the percentage of TGF-β1 and HPA- 1 positive cells were increased significantly ，while RBC ，the contents of TP and ALB were decreased significantly （P＜0.05 or P＜0.01）. Compared with model control group ，above ultrastructural changes of administration groups were improved to different extents ，and TGF-β1 and HPA- 1 positive cells were decreased. The 24 h UTP ，the percentage of TGF-β1 positive cells （except for SZD low-dose group），WBC（except for SZD alone groups and combination groups ），PLT and TC content （except for TPT group ），TG content （except for SZD low-dose alone and its combination group ），the percentage of HPA- 1 positive cells were decreased significantly ； the percentage of TGF-β1 positive cells in SZD high-dose+TPT group as well as the percentage of HPA- 1 positive cells in SZD+TPT groups were significantly lower than TPT group. RBC and GLU content （except for SZD low-dose group and TPT group ），TP and ALB content （except for SZD low-dose group ）were increased significantly ，while the content of GLU in SZD high-dose+TPT group was significantly higher than TPT tablets group （P＜0.05 or P＜0.01）. CONCLUSIONS ：SZD combined with TPT can relieve myelosuppression caused by TPT ，reduce proteinuria of MN model rats and improve pathological damage of renal tissue in rats. Its mechanism is related to the down-regulation of protein expression of TGF-β1 and HPA- 1，and the reduction of TC and TG content in the blood.

Conclusions The fatigue-predominant subhealth reduces the mechanical pain sensitivity and increases the thermal pain sensitivity in mice.
ABSTRACT
Objective@#To investigate the health status of occupational mercury workers and reveal the effects of mercury exposure on the cardiovascular system.@*Methods@#In June 2019, a total of 2651 mercury workers participated in the occupational health examination between 2016-2018 from a thermometer manufacturing plant and a fluorescent lamp manufacturing plant were included in this study. Then, they were divided into a high-level mercury exposure group (425 workers whose urine mercury concentration >35 μg/g creatinine) and a low-mercury mercury exposure group (2226 workers whose urinary mercury concentration <35 μg/g creatinine) . Mercury concentration in the workplace was also detected. Finally, the results of electrocardiogram (ECG) , blood routine, blood biochemistry and other physical examinations were analyzed. The measurement data of age and exposure years were analyzed by test. Urinary mercury and blood parameters were analyzed by Mann-Whitney nonparametric test. Chi-square test was used for the analyses of gender, ECG abnormality rate and other categorical data.@*Results@#The 8-hour weighted average allowable concentration (CTWA) of mercury in the workplace of high-exposure group was 0.002 2-0.152 mg/m3. The abnormal rate of ECG in the high-exposed group (29.6%) was higher than that in the low-exposure group (10.1%) in 2018 (P<0.01) . Compared with the low-exposure group, the WBC of the high-exposure group from 2016 to 2018 was increased, with statistically significance (P<0.05) ; the RBC of the high-exposure group in 2016 and 2017 was decreased, with statistically significance (P<0.01) ; the total bilirubin concentration in the high-exposure group was decreased from 2016 to 2018, with statistically significance (P<0.05) .@*Conclusion@#Long-term exposure to high concentration of mercury in the workplace may influence cardiovascular system. Therefore, engineering protection and individual protection should be implemented well.
ABSTRACT
Objective To investigate the differences in genotypes and phenotypic parameters of β-thalassemia gene carriers in pregnant women′s from Chengdu, Sichuan Province.Methods Totally 320pregnant women′s withβ-thalassemia gene from March 2016to June 2017in our hospital were selected.Routine blood tests, alkaline hemoglobin electrophoresis and routine analysis ofβ-thalassemia were performed on all the cases.Statistical analysis was performed on the data of each group.Results There were 306cases of heterozygousβmutations and 10types of mutations, among which 14cases ofα-thalassemia combined had 6types of mutations.The mutations of MCV, MCH, MCHC, and Hb in the routine blood tests of each group showed some differences.The incidence of abnormal bands was also different for each mutation, and the hemoglobin electrophoresis results ofβEM mutations contained abnormal bands.However, the clinical manifestations of CAPM mutations were not obvious and easily missed.Conclusion There is a certain regional specificity inβthalassemia gene carrying in Chengdu area.Targeted examination in the preliminary screening and prenatal diagnosis should be conducted so as to reducing the birth rate of children′s with severe thalassemia.
ABSTRACT
Objective To observe the significance of preoperative peripheral serum inflammatory cyto-kines and blood routine in predicting postoperative DVT in patients with neurosurgery.Methods A total of 156 pa-tients from the Department of Neurosurgery form April 2016 to April 2017 were recruited in this study.According to the incidence of postoperative deep venous thrombosis(DVT),patients were divided into DVT group(48 cases) and non-DVT group(108 cases). The date blood routine(including hematocrit,hemoglobin,neutrophil count, monocyte count,white blood cell count,platelet count)and serum inflammatory cytokines(including TNF-α,IL-1β,IL-1β,IL-6,IL-8)of two groups by t tests were compared.The possible risk factors for postoperative DVT in neurosurgical patients were analyzed by multivariate analysis logistic regression.The predicted cutoff value is deter-mined by plotting the subject's working characteristic(ROC)curve.Results Between the control group and DVT group,there were significant differences in preoperative blood neutrophil count,hemoglobin,TNF-α,IL-6 and IL-8(P < 0.05). Multivariate analysis logistic regression showed that the level of neutrophil count and concentration of serum TNF-α concentration were increased,indicating they may be the risk factors of DVT.For the neutrophilic granulocyte count,the value of specificity and sensibility was 82.7%and 61.7%respectively.For the TNF-α level, the value of specificity was 72.3% and the value of sensibility was 83.1%. Conclusion The level of preoperative neutrophil count and the concentration of TNF-α have value in predicting the occurrence of postoperative DVT in neurosurgical patients.
ABSTRACT
Objective To explore the new clinical significance of these routine test indexes and find the early biomarkers for predicting hypertension disorder complicating pregnancy(HDP) by the comparative analysis between pregnant women with HDP and normal pregnant women before 20 weeks,including biochemical,blood coagulation and blood routine indexes.Methods A case-control study was conducted to review the clinical data of pregnant women who were undertaken prenatal examination and delivered in Guangzhou Women and Children's Medical Center from 2012 to 2016.The pregnancy were divided into HDP group and control group according to the gestational week and age.Analyzed the related test indexes before 20 weeks of pregnancy.The two groups variables were analyzed by Kolmogorov-Smirnov for normal distribution.Approximate measurement data of normal distribution were mean± standard deviation (x± s) for statistical description,while the data of the skewed distribution was median and percentile[M(P25～P75)]for statistical description.The diagnostic value was analyzed by logistic regression equation and receiver operating characteristic curves (ROC).Results The level of biochemical indexes (AST,γ GT and UA) of HDP group was significantly higher thanthe normal group (t=2.50,3.34,4.56,P＜ 0.05).Meanwhile the level of blood indexes (RBC,PLT and HCT) of HDP group was significantly higher than the normal group (t=2.89,4.51,3.29,all P＜0.01).Other indicators of two groups (ALT,TBIL,Cr,Urea,PT,APTT,TT,FIB and HGB) were not significantly different (t=0.25～ 1.85,all P＞0.05).Then the logistic regression model equation was Y=-5.497+0.010 * PLT+0.043 * γ-GT+0.007 * UA+0.045 * AST.The area under ROC curve (AUC) was 0.746 for the combination of the four indexes.The combination resulted in a higher sensitivity of 0.818 and specificity of 0.523.Conclusion Before 20 weeks of gestation,compared with normal group,liver and kidney function in patients with HDP and high blood coagulation state was damaged.Can by combined detection of AST,UA,γ-GT and PLT index,early prevention and diagnosis of gestational hypertension,effective intervention measures taken as soon as possible to improve the prognosis of pregnancy.
ABSTRACT
OBJECTIVE: To compare the effects of different anesthetics and blood sampling methods on blood routine test results in experimental animals. METHODS: A total of 42 specific pathogen free( SPF) male Sprague Dawley( SD) rats and 59 SPF male Kunming( KM) mice were randomly divided into 4 groups( control group,ether group,chloral hydrate group and pentobarbital sodium group). Ether group animals were treated with ether inhalation anesthesia; animals in chloral hydrate group and pentobarbital sodium group were injected intraperitoneally with chloral hydrate or pentobarbital sodium. The control group received no anesthesia treatment. Blood samples were collected by different ways: orbital venous plexus,abdominal aorta or eyeball enucleation. White blood cell( WBC) count,red blood cell( RBC) count,platelet(PLT) count,hemoglobin(Hb) level and hematocrit(HCT) in blood samples were analyzed. RESULTS: The RBC count,Hb level and HCT of SD rats in pentobarbital sodium group were significantly lower than those in control group( P <0. 05). The HCT of SD rats in ether group was lower than that in control group( P < 0. 05). The WBC count of orbital venous plexus of KM mice was lower than that taken by eyeball enucleation in control group( P < 0. 05),but the WBC count of orbital venous plexus was higher than that taken by eyeball enucleation in chloral hydrate group( P < 0. 05). The RBC count,Hb level,HCT of KM mice in pentobarbital sodium group were significantly lower than those in control group(P < 0. 05). CONCLUSION: The anesthetic can affect the blood routine test results of experimental animals. Different blood sampling methods have effects on blood routine test results of KM mice.
