ABSTRACT

Objective:To study the variation in activity in patient′s body with differentiated thyroid cancer (DTC) treated with 131I and external dose level, analyze the relationship between the both, and estimate the correction factor for the dose equivalent rate for the patients with residual activity of 400 MBq. Methods:A total of 43 DTC patients who received 131I therapy for the first time after total thyroidectomy were studied. The dose was 1 850-3 700 MBq and average dose was (2 405±777) MBq. The measurements of residual activity in patient′s body and of dose equivalent rate at 0.3, 1 and 3 m in front of the patients were performed at 2, 6, 20, 22, 24, 27, 30, 44, 46, 48, 54, 68 and 72 h after administration of 131I. Results:The residual activity in patient′s body after 131I therapy varied with time as a function of A= A0 (1.033 16e -0.062 4t+ 0.017 17). It can be estimated that the effective half-life of DTC patients treated with thyroid remnant 131I ablation therapy is 12.19 h. It needs only 26.4-38.9 h to reduce the internal activity to the 400 MBq. The functions of variation with time of normalized dose equivalent rate at 0.3, 1, and 3 m away from patients were: H· 0.3=127.220 7e -0.054 8t+ 3.765 71; H· 1=30.225 8e -0.064 4t+ 0.824 67; and H· 3=4.161 9e -0.061 5t+ 0.167 97, respectively. There was a positive correlation between residual activity and dose equivalent rate at 1 m ( r=0.982, P<0.05), and the function is H· 1=0.025 A+ 1.245. When residual activities in DTC patient′s body were 1 000, 700 and 400 MBq, the corresponding dose equivalent rates at 1 m from patients were 26.2, 18.7 and 11.2 μSv/h, respectively. The correction factors for dose equivalent rate at 0.3, 1 and 3 m from patients with 400 MBq were 0.25, 0.49 and 0.70, respectively. Conclusions:DTC patients with administration of 131I activity below 3 700 MBq need only to be hospitalized for two days to reach the discharge standards. When the residual activity in DTC patient′s body drops to 400 MBq, the dose equivalent rate at 1 m is far less than 25 μSv/h. Simply using the point source formula to estimate the dose equivalent rate around the patient will result in overestimation. Therefore, the correction factor used in the estimation of radiation doses to patients by using the formula needs to be further studied so as to make the model-based estimated result more consistent with the actual situation.

ABSTRACT

Objective:To explore the effect of celastrol in inhibiting the lipid metabolism disorder in hepatic L02 cells and its possible mechanism on endoplasmic reticulum stress (ERS) of non-alcoholic fatty liver cells by intervening non-alcoholic fatty liver disease(NAFLD) cell model with celastrol. Method:Hepatic L02 cells were divided into control group, model group, low-dose celastrol treatment group (Cel 0.5 mg·L-1), high-dose celastrol treatment group (Cel 1 mg·L-1) and simvastatin group (SIM 6 mg·L-1) for cultivation. The contents of total cholesterol (TC) and total triglyceride (TG) in hepatic L02 cells were detected, and the oil red staining was used to detected the lipid accumulation in hepatic L02 cells. Reverse transcription polymerase chain reaction (RT-PCR) and Western blot were used to detect the mRNA and protein expression levels of endoplasmic reticulum stress (ERS)-related signal molecules activating transcription factor 6 (ATF6), glucose regulated protein 78 (GRP78), inositol-requiring enzyme 1 (IRE1), sterol regulatory element-binding protein cleavage-activating protein (SCAP), sterol regulatory element-binding protein-1c (SREBP-1c) and sterol regulatory element-binding protein-2 (SREBP-2) in hepatic L02 cell model respectively. Result:The contents of TC and TG in hepatic L02 cells of NAFLD group were significantly higher than those in control group (P-1 group, Cel 1 mg·L-1 group and SIM 6 mg·L-1 group were significantly lower than those in NAFLD group (P-1 group, the Cel 1 mg·L-1 group, and the SIM 6 mg·L-1 group were lower than the NAFLD group to different degrees. According to the results of RT-PCR and Western blot, the mRNA transcription and protein expression levels of ERS-related signaling molecules ATF6, GRP78, IRE1, SCAP, SREBP-1c and SREBP-2 in hepatic L02 cells of NAFLD group were higher than those of control group (P-1 group, Cel 1 mg·L-1 group and SIM 6 mg·L-1 group were lower than those of NAFLD group (P-1 group and the SIM 6 mg·L-1 group. Conclusion:Celastrol can reduce the lipid metabolism disorder in hepatic L02 cells by down-regulating the expressions of ERS-related signaling molecules ATF6, GRP78, IRE1, SCAP, SREBP-1c and SREBP-2 in hepatic L02 cells, so as to improve NAFLD.

ABSTRACT

Objective To explore the effect of corpus luteum blood flow measured by three-dimensional power Doppler ultrasound on pregnancy in elderly women.Methods We selected 464 elderly women with normal ovulation who came to the First Affiliated Hospital of Xi'an Jiaotong University from January 2016 to July 2017 as study group.Another 436 women aged less than 35 years old who planned pregnancy in the same period were selected as control group.The clinical data were compared between the two groups.Results There was no significant difference in average diameter of dominant follicles and endometrial thickness at each monitoring point between the two groups (P>0.05).There was no significant difference in corpus luteum blood flow grade 1 day after ovulation (P>0.05),but corpus luteum blood flow grade 7 to 9 days after ovulation in study group was significantly reduced as compared with control group (P<0.05).The two groups did not differ significantly in corpus luteum volume (V)or vascular parameters 1 day after ovulation,corpus luteum V 7-9 days after ovulation (P>0.05).However,luteum vascularization index (VI),flow index (FI)and vascularization flow index (VFI) significantly decreased in study group compared with control group (P<0.05).Biochemical pregnancy rate and clinical pregnancy rate were 1 6 .3 8% and 9 .05 % in study group ,which were significantly lower than 2 3 .1 7 % and 19.04% in control group,respectively (P<0.05).Miscarriage rate of biochemical pregnancy in study group was 7. 33%,significantly higher than 4.13% in control group (P<0.05).Corpus luteum V and vascular parameters in women with biochemical pregnancy abortion in both groups were significantly lower than those with clinical pregnancy (P<0.05).Conclusion The decreased of blood supply of the corpus luteum in embryo implantation window of elderly women may be related to the reduction of endometrial receptivity and pregnancy rate.Regardless of old age,biochemical pregnancy abortion is likely to lead to loss of corpus luteum blood supply,which results in pregnancy failure.

ABSTRACT

Objective To investigate the relationship between body composition and adequacy of dialysis,and analyze the related risk factors for inadequate delivery of hemodialysis.Methods In a prospective clinical trial,two different methods determining dialysis dose were simultaneously applied:Kt/Vdau (conventional method with Daugirdas' formula) and Kt/Vbem [online clearance monitoring (OCM) measurement with Ⅴ measured by body composition monitor (BCM)].Using the value of 1.27 as the boundary,the patients were divided into two groups:Kt/Vbcm < 1.27 group and Kt/Vbcm≥ 1.27 group.Clinical indices were compared between the two groups.Multiple linear regression was applied to analyze the potential impact factors of the difference between Kt/V values calculated by the two methods.Receiver operator characteristic (ROC) curve was applied to analyze meaningful factors.Results A total of 138 maintenance hemodialysis patients with age of (54.9±12.7) years old were enrolled,and 55.1% of them were males.There was no significant difference between Kt/Vdau and Kt/Vbcm [1.432(1.235,1.718) vs 1.434 (1.244,1.642),P=0.823].Kt/Vdau was incidentally prone to falsely high values due to operative errors,whereas in these cases OCM-based measurement Kt/Vbcm delivered realistic values.An excellent correlation was observed between Kt/Vdau and Kt/Vbcm;the mean difference was 0.07,95%CI (-0.66-0.79);the correlation coefficient was 0.842(0.821-0.862).The patients in Kt/Vbcm≥ 1.27 group had older age,lower body mass index (BMI),lower height and weight,lower total body water (TBW),lower extracellular water,lower intracellular water,and lower lean tissue index (LTI) compared to those in Kt/Vbcm < 1.27 group.Excellent correlations were observed between Kt/Vbcm and TBW or LTI (r=-0.834,P < 0.001;r=-0.721,P < 0.001).ROC curve analysis showed that the sensitivity and specificity of predicting inadequate delivery of hemodialysis were 87.1% and 86.5%,with a threshold of 30 L for TBW.It also showed that the sensitivity and specificity of predicting inadequate delivery of hemodialysis were 60.4% and 94.6%,with a threshold of 11.05 kg/m2 for LTI.Conclusions BCM can give more accurate parameters of urea distribution volume,thus modifying the result of Kt/V.TBW and LTI are important risk influencing factors for inadequately dialysis,and special attention should be paid to patients with TBW > 30 L or LTI > 11.05 kg/m2.

ABSTRACT

Objective To investigate the effect of gradient heat stress on phagocytosis of hepatic Kupffer cells (KCs) in vitro in rats. Methods Rat Kupffer cells were isolated in vitro and the temperature for gradient heat stress was set at 37, 39, 41 and 43℃. After thermal stimulation, cell injury was detected by PI and Hochest33342 staining. CCK-8 assay was used to investigate difference in cellular proliferation rate over 24h between the groups. Flow cytometry was used to investigate the influence of heat stress on the phagocytosis of KCs. Results Compared to the normal control group, cells in each heat stress group exhibited varying degrees of damage, especially cells in 43℃ group. The ratio of damage cells increased with the increase of heat stress severity (P<0.05). Proliferation assay indicated that the proliferation rate of cells in each heat stress group was significantly decreased in comparison with normal control group 6h after heat stress (P<0.05). After 12h recovery, decrease in proliferation rate was observed only in 43℃ group (P<0.001), and no difference in the rate of proliferation could be observed between the heat stress groups and normal control group after 24h recovery. Flow cytometry showed, that the phagocytosis of KCs decreased in heat stress groups compared with control group, especially in 43℃ group (P<0.05). This phenomenon disappeared after 24h recovery. Conclusion Heat stress can inhibit the phagocytosis of rat liver KCs through its cytotoxic effect on KCs, and subsequently inhibits its proliferative ability. Further investigation of the effect of heat stress on KCs may help understand the pathogenesis of heat stress.

ABSTRACT

On basis of the idiosyncratic lipopolysaccharide(LPS)-mediated hepatotoxicity model, liver injury induced by Zhuangguguanjie wan(ZGW)was evaluated, and the mechanism was explored. Idiosyncratic hepatotoxicity model was established in rats by injecting LPS at a dosage of 2.8 mg·kg-1. Rats were randomly divided into the normal control group, LPS group, ZGW group and LPS+ZGW group. Alanine aminotransferase(ALT)and aspartate aminotransferase(AST)activities were analyzed in serum; pathological changes(HE staining)and the content of cytokines of liver were tested; and immune cell subpopulation ration were determined in blood and liver. Compared with the control group, the ZGW group and LPS group had no significant changes in ALT, AST and liver pathology(P> 0.05); while the ZGW+LPS group exhibited an elevation in ALT and AST(P< 0.05). Disorder of liver lobular arrangement and irregular island-like or massive necrosis of liver cells were observed in the group. Several cytokines in the liver were increased in LPS group and ZGW+LPS group(P< 0.05 or P< 0.01), and the level in ZGW+LPS group was higher than that of LPS group. Compared with the control group, the ratio of CD3+ T cell/lymphocyte of blood in LPS group was significantly decreased(P< 0.01); while the percentage of CD3+ T cells in the liver were significantly increased(P< 0.05). The contents of immune cells of blood had no significant changes between LPS group and ZGW+LPS group(P> 0.05). CD3+ T cell in the liver of ZGW+LPS group was significantly increased over the LPS group(P< 0.05). Aggregation or activity of CD3+ T cell was increased by ZGW combined with LPS. These results suggest that ZGW could promote T lymphocyte recruitment to liver under the immune activation state leading to inflammatory response, which may contribute to idiosyncratic liver injury.

ABSTRACT

BACKGROUND:In recent years, with the in-depth research on thecharacteristics and functions of stem cells,stem cell research has become a hot research targeting thetreatment of a variety of diseases.OBJECTIVE:To summarize the research progress of human amnioticmesenchymal stem cells in the treatment of acute lung injury.METHODS:The PubMed and CNKI databases were searched by computerfor relevant literatures published from January 2000 to January 2017. The key words were mesenchymal stem cells, acute lung injury in Chinese and English,respectively.RESULTS AND CONCLUSION:As an important member of adult stem cells, human amniotic mesenchymal stem cells not only have the advantages and characteristics of most other stem cells, but also have unique advantages, such as these cells can be extracted from a vast of sources, require only non-invasive operations, and involve no violation of ethics. Human amniotic mesenchymal stem cells can be driven by inflammation reaction and homing to the damaged tissue, and be activated by inflammatory factors to secrete a variety of cytokines in a paracrine fashion, which inhibit neutrophils, macrophages and other immune cell migration and inhibit dendritic cell maturity, and reduce the proliferation of NK cells, B lymphocytes and T lymphocytes, and up-regulate anti-inflammatory cytokines and down-regulate proinflammatory cytokines, and alleviate alveolar inflammatory injury through anti-oxidation and anti-apoptotic processes. Human amniotic mesenchymal stem cells can also assist in the repair or homing to the damaged tissue to directionally differentiate to replace the apoptotic and necrotic cells. All of these characteristics of human amniotic mesenchymal stem cells provide new insight into the treatment of acute lung injury. As acute lung injury is caused by many pathogenic factors and its pathophysiological process is very complicated, human amniotic mesenchymal stem cell transplantation in the treatment of acute lung injury has many issues to be resolved.

ABSTRACT

ObjectiveTo compare the clinical effect between laparoscopic retrograde cholecystectomy and partial cholecystectomy in the treatment of patients with complex bile duct diseases. MethodsThe clinical data of 83 patients with bile duct diseases who were diagnosed and treated in Guangyuan Mental Health Center from June 2013 to March 2015 were collected. Among these patients, 40 underwent laparoscopic retrograde cholecystectomy (group A), and 43 underwent partial cholecystectomy (group B). The surgical procedure and postoperative recovery were compared between the two groups. The independent samples t-test was applied for comparison of continuous data between groups, and the paired t-test was applied for comparison of continuous data within each group before and after treatment; the chi-square test was applied for comparison of categorical data between groups. ResultsCompared with group A, group B had a significantly shorter time of operation, a significantly less blood loss, a significantly lower volume of intraoperative fluid infusion, and a significantly lower volume of peritoneal drainage (t=9.245, 2.394, 2.529, and 3.603, all P<0.05). The rate of conversion to laparotomy, time to functional recovery of the gastrointestinal tract, and length of hospital stay showed no significant differences between the two groups (all P>0.05). The body temperature and C-reactive protein on days 1-3 after surgery showed no significant differences between the two groups (all P>005), while in both groups, the body temperature and C-reactive protein were significantly lower on the 2nd and 3rd days than on the 1st day. (t=3.184, 3.402, 3.151, 3.390, 3.497, 5.184, 3.916, and 6.024, all P<0.05). Group B had a significantly lower incidence of postoperative complications than group A (2.33% vs 20.00%, χ2=6.696, P=0.010). ConclusionCompared with laparoscopic retrograde cholecystectomy, partial cholecystectomy can shorten the time of operation and reduce intraoperative bleeding and postoperative complications, and holds promise for clinical application.

ABSTRACT

OBJECTIVE@#To study the effect of immune formulation-assisted conventional therapy on anti-infective ability of multidrug-resistant Mycobacterium tuberculosis infection mice.@*METHODS@#BALB/c mice were used as experimental animals, multidrug-resistant M. tuberculosis infection models were built, randomly divided into model group, moxifloxacin group, thymopentin group and combined treatment group and given corresponding drug intervention, and then colony numbers in the spleen and lung, T lymphocyte subset contents and programmed death-1 (PD-1) expression levels in peripheral blood were detected.@*RESULTS@#Colony numbers in lung and spleen of moxifloxacin group and thymopentin group were significantly lower than those of model group and colony numbers in lung and spleen of combined treatment group were significantly lower than those of moxifloxacin group and thymopentin group; contents of CD3(+)CD4(+)T cells, Th1 and Th17 in peripheral blood of moxifloxacin group and thymopentin group were higher than those of model group, and contents of CD3(+)CD8(+)T cells, Th2 and Treg were lower than those of model group; contents of CD3(+)CD4(+)T cells, Th1 and Th17 in peripheral blood of combined treatment group were higher than those of moxifloxacin group and thymopentin group, and contents of CD3(+)CD8(+)T cells, Th2 and Treg were lower than those of moxifloxacin group and thymopentin group; PD-1 expression levels on T lymphocyte, B lymphocyte and monocyte surface in peripheral blood of moxifloxacin group and thymopentin group were lower than those of model group, and PD-1 expression levels on T lymphocyte, B lymphocyte and monocyte surface in peripheral blood of combined treatment group were lower than those of moxifloxacin group and thymopentin group.@*CONCLUSIONS@#Immune formulation thymopentin can enhance the anti-infective ability of multidrug-resistant M. tuberculosis infection mice, decrease bacterial load in lung and spleen, and enhance immune function.
