ABSTRACT

In vitro studies have established the prevalent theory that the mitochondrial kinase PINK1 protects neurodegeneration by removing damaged mitochondria in Parkinson's disease (PD). However, difficulty in detecting endogenous PINK1 protein in rodent brains and cell lines has prevented the rigorous investigation of the in vivo role of PINK1. Here we report that PINK1 kinase form is selectively expressed in the human and monkey brains. CRISPR/Cas9-mediated deficiency of PINK1 causes similar neurodegeneration in the brains of fetal and adult monkeys as well as cultured monkey neurons without affecting mitochondrial protein expression and morphology. Importantly, PINK1 mutations in the primate brain and human cells reduce protein phosphorylation that is important for neuronal function and survival. Our findings suggest that PINK1 kinase activity rather than its mitochondrial function is essential for the neuronal survival in the primate brains and that its kinase dysfunction could be involved in the pathogenesis of PD.

ABSTRACT

OBJECTIVE:To explore the therap eutic effects and its mech anism of Jianpi yiqi decoction on diethylnitrosamine (DEN)induced liver cancer model rats. METHODS :Totally 80 male SD rats were divided into normal group ,model group , Nod-like receptor family 3(NLRP3)inhibition group (MCC950,4.5 mg/kg),caspase-1 inhibitory group (VX-765,4.5 mg/kg), Jianpi yiqi decoction low-dose ,medium-dose and high-dose groups (5.25,10.5,21 g/kg),with 10 rats in each group except for 20 rats in model group (10 of them were only used to judge whether modeling was successful ). Rats in each group were intraperitoneally injected with DEN (70 mg/kg)to induce liver cancer model ,except for the rats in normal group which were replaced by normal saline. After modeling ,normal group and model group were given normal saline intragastrically ;inhibitor groups were given relevant medicine intraperitoneally ;Jianpi yiqi decoction groups were given relevant medicine intragastrically , once a day ,for consecutive 4 weeks. After last administration ,histopathological morphology of liver tissue was observed. The contents of serum inflammatory factors TNF-α and IL-1β were detected. The expression of NLRP3 and programmed cell necrosis associated protein (ASC,pro-caspase-1,RIP1,RIP3 and MLKL )in liver tissue were detected. RESULTS :Compared with the normal group ,the hepatocytes of model group showed varying, degrees of steatosis ,enlarged nuclei ,lumpy,bleeding and necrosis,accompanied by proliferative foci and nodules. Liver 198086, tissue injury index ,serum content of TNF-α and IL-1β as well as the protein expression of NLRP 3,ASC,pro-caspase-1,RIP1,RIP3 and MLKL in liver tissue were significantly increased (P<0.05 or P<0.01). Compared with model 防治。E-mail:sherwin_zhuo@126.com group,there were still a large number of inflammatory cell infiltration in the liver tissue of rats in Jianpi yiqi decoction low-dose and medium dose groups ,while the inflammatory cell infiltration of rats in high-dose group and inhibitor groups decreased significantly ;the liver tissue injury index and above indexes levels in serum and liver tissue were decreased significantly (P<0.05 or P<0.01). CONCLUSIONS :Jianpi yiqi decoction shows therapeutic effect on liver cancer model rats ,the mechanism of which may be associated with down-regulating the expression of NLRP3 inflammasome and inhibiting programmed cell necrosis.

ABSTRACT

Objective:To investigate the clinicopathological characteristics and influencing factors of kidney prognosis in primary IgA nephropathy (IgAN) patients.Methods:The data of primary IgAN patients diagnosed with renal biopsy in the First Affiliated Hospital of Anhui Medical University from January 2015 to September 2019 were retrospective analyzed. According to the level of baseline estimated glomerular filtration rate (eGFR) when performing renal biopsy, the patients were divided into group A[eGFR≥90 ml·min -1·(1.73 m 2) -1], group B[eGFR 61-89 ml·min -1·(1.73 m 2) -1] and group C[eGFR≤60 ml·min -1·(1.73 m 2) -1]. The clinical and pathological data were collected and compared among the three groups. Kaplan-Meier method was conducted for renal results, whereas the Cox proportional-hazards regression model was exploited to analyze the influencing factors of kidney prognosis in IgAN patients. Results:A total of 742 patients were included in the study, including 394 cases (53.1%) in group A, 203 cases (27.4%) in group B, and 145 cases (19.5%) in group C. There were 325 males (43.8%) and 417 females (56.2%). The median duration of renal biopsy was 6 (1, 24) months, and the median age was 36 years old (18-68 years old). As the baseline level of renal function decreased, the proportion of patients with nephrotic syndrome, hypertension, anemia and hyperuricemia and the levels of 24 h urinary protein, serum triglyceride and total cholesterol increased significantly (all P<0.05), while the proportion of gross hematuria episodes and the ratio of serum albumin to globulin significantly decreased (all P<0.05). For the aspect of pathological manifestations, the proportions of cell proliferation in capillaries (E1), segmental sclerosis or adhesion (S1), renal tubular atrophy or interstitial fibrosis (T1/2), globular sclerosis, renal arteriole wall thickening and vitreous degeneration, Lee's grade Ⅳ and Ⅴ increased with the decrease of baseline renal function (all P<0.05). Kaplan-Meier analysis showed that the cumulative renal survival rate decreased with the decline of baseline renal function (Log-rank χ2=88.510, P<0.001). As a result of multivariate Cox regression analysis, nephrotic syndrome ( HR=2.399, 95% CI 1.054-5.459, P=0.037), hypertension ( HR=1.806, 95% CI 1.071-3.048, P=0.027), low baseline eGFR (taking group A as the reference, group B: HR=2.383, 95% CI 1.053-5.392, P=0.037; group C: HR=6.878, 95% CI 3.074-15.393, P<0.001), IgG deposition ( HR=2.224, 95% CI 1.384-3.574, P=0.001) and globular sclerosis ( HR=2.075, 95% CI 1.230-3.501, P=0.006) were the independent influencing factors for renal progression in primary IgAN patients. Conclusions:The level of baseline renal function in primary IgAN patients can be used to predict the extent of clinic-pathological damage. Nephrotic syndrome, hypertension, low baseline eGFR, IgG deposition and globular sclerosis are the independent influencing factors for renal progression in primary IgAN patients.

ABSTRACT

Objective:To investigate the impacts of the composition and physical density of tissue on the dose distribution of implanted 125I seeds, in order to provide references for the clinical dose calculation and assessment of implanted radioactive particles. Methods:The OncoSeed 6711 physical model of 125I seeds was established using thes of twareegs_brachy and was validated through the calculation of dose rate constant and the radial dose function [ g( r)] in water. Then, based on the element composition and physical density of different types of tissue, the g( r) and absorbed dose ratein water, prostate, breast, muscle, and bone were calculated. Results:The calculated dose rate constant (0.950 cGy·h -1·U -1) and g( r)in water approached the values in related literature. The absorbed dose in bone was 6.042 times than that in water at a distance of 0.05 cm from the implanted source. The difference between the absorbed doses in breast and water was more than 10% at a distance of less than 1.7 cm from the implanted source. The difference between the absorbed doses in prostate/muscle and water was less than 5% at the same radial location. Conclusions:The dose distribution of 125I seeds in some types of human tissue is significantly different from that in water, which should be carefully considered in clinical dose calculation.

ABSTRACT

Objective:To evaluate the impacts of tissue heterogeneity on dose calculation of cervical brachytherapy by comparing the doses calculated by two clinically used dose calculation method and the CT image-based Monte Carlo (MC) method.Methods:This study retrospectively selected 11 patients with cervical cancer treated with 3D brachytherapy in Anhui Provincial Cancer Hospital from January 2018 to June 2020. The dose distribution of each plan was calculated via three methods, dose calculation method described in American Association of Physicist in Medicine(AAPM) Task Group No. 43 Report (TG43-BT), Acuros BV(BV-BT) used to perform accurate dose calculations in high-dose-rate (HDR) brachytherapy with phantom heterogeneity, and CT image-based EGSnrc tool kit used to perform Monte Carlosimulation (MC-BT). The dose volumes( V3 Gy, V6 Gy, V9 Gy, and V12 Gy), target volume doses( D98, D90, D50), D2 cm 3 of organs at risk (OARs) calculated by the three methods were compared. Results:The HRCTV D90obtained by TG43-BT was 6.274 Gy, which was even overestimated by around 5% compared to the result calculated by MC-BT. Meanwhile, TG43-BT overestimated the dose volumesand the target volume doses compared to MC-BT.Except for D50 and V12 Gy, the differences between the doses to tumor calculated by BV-BT and MC-BT were not statistically significant( P>0.05). There was also no significant statistical difference between the D2 cm 3 of rectum, small intestine, and sigmoid calculated by BV-BT and MC-BT ( P>0.05). In contrast, the dose to D2 cm 3 of bladder determined by MC-BT was 4.609 Gy, which was notably higher than those deter mined by TG43-BT and BV-BT. Conclusions:TG43-BT overestimated the doses to tumor targets and most OARs since the effects of tissue heterogeneity were not taken into consideration. BV-BT performed efficient calculation and most of the dose distributionin target volume and OARs obtained by BV-BT were consistent with that calculated by MC-BT. Nevertheless, low accuracy occurred for the regions near the sources and full bladder, which warrants further caution in clinical evaluation.

ABSTRACT

Objective:Non-alcoholic fatty liver disease (NAFLD) is not only a liver manifestation of metabolic syndrome, but also related to type 2 diabetes, dyslipidemia and hypertension closely. This study aims to explore the correlation between clinical and experimental indexes and disease occurrence in patients with NAFLD combined with essential hypertension.Methods:One hundred and thirty-four patients with NAFLD combined with essential hypertension and 98 patients in the control group were enrolled in this study from March 2019 to March 2021 in Dalian Central Hospital. The clinical baseline and test indexes of the two groups were compared and analyzed, and the logistic regression analysis was also performed.Results:The mean and median values of alanine aminotransferase, γ-glutamyl transpeptidase, lactate dehydrogenase and triacylglycerol in the experimental group were higher than those in the control group: 22 U/L vs. 17 U/L, 23 U/L vs. 17 U/L, 179 U/L vs. 173 U/L, 1.68 mmol/L vs. 1.45 mmol/L, while the mean and median values of homocysteine, albumin (ALB), creatinine and free triiodothyronine were lower than that in the control group: 11.2 μmol/L vs. 12.2 μmol/L, 41.5 g/L vs. 43.5 g/L, 54 μmol/L vs. 60 μmol/L, (4.657 ± 0.599) pmol/L vs. (4.850 ± 0.574) pmol/L ( P<0.05). Multivariate Logistic regression analysis showed that BMI, diabetes and ALB were independently correlated with NAFLD. Conclusions:The BMI and diabetes were independent risk factors for NAFLD in patients with essential hypertension, and ALB is an independent protective factor.

ABSTRACT

Objective To understand the real prevalence of Clonorchis sinensis infections in the freshwater fish in mainland China, so as to provide insights into clonorchiasis control and detection of freshwater fish. Methods All literatures reporting the prevalence of C. sinensis infections in the freshwater fish, the second intermediate host of the parasite, were jointly retrieved in Chinese and English electronic databases from January 1, 2010 to December 31, 2020, including Wanfang Data, CNKI, PubMed, Web of Science, Embase and Cochrane Library. All studies were screened based on inclusion and exclusion criteria, and the quality of all enrolled literatures was evaluated. The pooled prevalence of C. sinensis infections in freshwater fish and its 95% confidence interval (CI) were estimated using the software Stata version 15.0, and subgroup analyses were performed to investigate the region-, season- and sample source-specific pooled prevalence of C. sinensis infections in freshwater fish. In addition, the sensitivity and publication bias of all included studies were analyzed. Results A total of 40 eligible literatures were included in this study, including 37 Chinese literatures and 3 English literatures, and there were 10 high-quality literatures, 27 moderate-quality literatures and 3 low-quality literatures. A total of 53 species containing 37 959 freshwater fish were reported in these 40 studies, and 73.58% (39/53) of freshwater fish species were identified with C. sinensis infections. Meta-analysis showed 23.5% [95% CI: (0.19, 0.28)] pooled prevalence of C. sinensis infections in freshwater fish in mainland China, and subgroup analyses higher prevalence of C. sinensis infections in freshwater fish in northeastern China [35.7%, 95% CI: (0.22, 0.50)] than in central [25.9%, 95% CI: (0.04, 0.48)] and southern China [20.6%, 95% CI: (0.09, 0.32)], higher prevalence of C. sinensis infections in freshwater fish sampled in spring [44.1%, 95% CI: (0.35, 0.53)] than in autumn [6.7%, 95% CI: (0.05, 0.08)] and summer [3.3%, 95% CI: (−0.01, 0.07)], and higher prevalence of C. sinensis infections in freshwater fish sampled from natural water [25.2%, 95% CI: (0.17, 0.33)] than from retail trades [22.2%, 95% CI: (0.17, 0.28)] and breeding chain [12.3%, 95% CI: (0.03, 0.22)]. However, all included studies had a publication bias with a low sensitivity. Conclusions The prevalence of C. sinensis infections is high in freshwater fish in mainland China, and there are still challenges for clonorchiasis control. Reinforcement of health education, diagnostics development and food safety supervision is recommended in future clonorchiasis control programs.

ABSTRACT

Objective:To explore the application of a 3D printed patient-specific guider (3D-PSG) in complex total knee arthroplasty (TKA).Methods:A retrospective analysis was performed of the data of 44 patients who had received complex artificial TKA for articular and extra-articular deformities of the knee from January 2016 to October 2019 at Department of Orthopaedic Surgery, Nanjing First Hospital. According to whether a 3D-PSG had been applied, the patients were divided into 2 groups. In the 3D-PSG group of 23 patients, there were 11 males and 12 females, with an age of 63.7 years ± 10.2 years (from 53 to 81 years); in the conventional group of 21 cases, there were 10 males and 11 females, with an age of 64.2 years ±12.1 years (from 51 to 79 years). In the 3D-PSG group, the preoperative CT data were 3D reconstructed for measurement of a full lower limb and design of a 3D-PSG and TKA was assisted by a 3D-PSG which had been manufactured by a 3D printer using the STL files of the 3D-PSG imported. In the conventional group TKA was performed in a standard manner. In the 3D-PSG group, the TKA surgical parameters in the preoperative plan were compared with actual surgical measurements. The 2 groups were compared in terms of operation time, intraoperative blood loss, postoperative drainage volume, length of hospital stay, visual analogue scale (VAS), Knee Society Score (KSS), hip knee ankle (HKA), frontal femoral component (FFC), frontal tibial component (FTC), lateral femoral flexion (LFF) and lateral tibial component (LTC).Results:There were no significant differences between the 2 groups in the preoperative general data, showing comparability ( P>0.05). In the 3D-PSG group, no significant differences were found between preoperative parameters designed and actual intraoperative measurements in the prosthetic type of femoral condyle (3.4±1.1 versus 3.5±0.9) or of tibial plateau (3.1±0.9 versus 3.3±1.2), or in the filler thickness (10.6 mm ± 3.2 mm versus 10.9 mm ± 4.7 mm) ( P>0.05). The 44 patients were followed up for an average of 10.8 months (from 7 to 13 months). The 3D-PSG group had significantly less operation time (65.7 min ± 10.5 min), intraoperative blood loss (19.8 mL ±7.3 mL), postoperative drainage volume (124.6 mL ± 27.9 mL) and hospital stay (7.3 d ± 2.5 d) than the conventional group (82.4 min ± 11.7 min, 86.5 mL ± 35.7 mL, 154.6 mL ± 21.3 mL and 10.6 d ± 3.1 d) ( P<0.05). The VAS and KSS scores at postoperative day 1, week 1 and week 2 in the 3D-PSG group were significantly better than those in the conventional group ( P<0.05). Significantly more patients in the 3D-PSG group achieved approximately ideal values in HKA, FFC, FTC, LFF and LTC than those in the conventional group ( P<0.05). Conclusion:A 3D printed patient-specific guider may improve surgical accuracy, reduce operation time and achieve better surgical outcomes in complex total knee arthroplasty.

ABSTRACT

Objective: To observe the improvement of androgen deficiency syndrome after endocrine therapy by "Jianpi Lishi Huayu Method" for advanced prostate cancer and its clinical effect. Methods: A total of 60 patients with advanced prostate cancer were randomly divided into observation group (30 cases) and control group (30 cases). The control group was treated with intermittent endocrine therapy (androgen blocking). The treatment group was treated with "Jianpi Lishi Huayu Decoction" on the basis of the control group. The end point of the study was the time to develop castration-resistant prostate cancer. ISS scale scores, disease progression-free survival, PSA, serum testosterone, I-PSS and TCM clinical symptom scores were compared between the two groups. Results: The median progression-free survival time of the patients in the observation group was 23 months, and there was no significant difference between the two groups. After treatment, the total ISS score, physical symptoms score, vasomotor symptoms score and psychosocial symptoms score in the observation group were significantly lower than those before treatment, and lower than those in the control group (P < 0.05). After treatment, the effective rate of ISS score in the observation group (73.33%) was significantly higher than that in the control group (16.67%); The PSA level in both groups decreased significantly after treatment, and the PSA level in the observation group (2.13 ± 0.58) ng/mL was better than that in the control group (5.30 ± 1.40) ng/mL (P < 0.05); There was no significant difference in serum testosterone between the two groups after treatment. After treatment, the I-PSS score and TCM clinical symptom score of the observation group and the control group were improved, and the observation group was better than the control group (P < 0.05). After treatment, the effective rate of the I-PSS score of the observation group (96.67%) and the improvement rate of TCM clinical symptom score (76.67%) were better than those of the control group (73.33%, 26.67%). Conclusion: On one hand, "invigorating spleen, draining dampness and removing blood stasis" method combined with endocrine therapy can prolong the time for hormone-dependent prostate cancer to develop into castrated resistant prostate cancer, improve clinical efficacy, reduce the level of tumor markers, stabilize the level of testosterone, and improve some androgen deficiency syndrome after endocrine therapy, especially in ovariectomized resistant prostate cancer. It has obvious advantages in improving physical symptoms, vasomotor symptoms and psycho-psychological symptoms. It can obviously alleviate adverse reactions after endocrine therapy. On the other hand, it can better improve clinical symptoms, reduce I-PSS scores and TCM clinical symptoms scores, improve the quality of life of patients, and give full play to the role of reducing TCM toxicity and increasing synergism efficiency.

ABSTRACT

The rule and characteristics of clinical acupoint selection were explored in treatment of puerperal insufficient lactation with acupuncture and moxibustion. The clinical articles on the treatment of puerperal insufficient lactation with acupuncture and moxibustion were retrieved from the databases of CNKI, VIP and Wanfang from the date of establishment to June 1, 2019. The articles were screened in accordance with the inclusion and exclusion criteria. The prescriptions of acupuncture and moxibustion were extracted and normalized. Using Microsoft Excel 2016 software, the use frequency, meridians involved and acupoint distributions were analyzed. Using SPSS Statistics 21.0 software, the cluster and factor analyses were conducted. Totally, 102 articles were included,108 acupoint prescriptions were extracted, 65 acupoitns were designed and the total use frequency was 654 times. The top three acupoints used in treatment of puerperal insufficient lactation were Danzhong (CV 17), Rugen (ST 18) and Shaoze (SI 1). The most frequently involved meridians were the stomach meridian, the conception vessel, the small intestine meridian and the liver meridian. The acupoints were mainly distributed in the chest and four extremities. It was showed in cluster analysis that Rugen (ST 18), Shaoze (SI 1), Zusanli (ST 36) and Danzhong (CV 17) represent 3 clusters and a total of 7 common factors were extracted. The acupoint selection is based on syndrome differentiation in treatment of puerperal insufficient lactation with acupuncture and moxibustion, of which, the local acupoints are predominated and the distal acupoints are combined.

ABSTRACT

BACKGROUND: LINC01234, a long noncoding RNA (lncRNA), is overexpressed in several cancers, including colorectal cancer (CRC). We investigated the role of LINC01234 in CRC development and confirmed its correlation with Krüppel-like factor 6 (KLF6), a tumor suppressor gene that is dysregulated in CRC. METHODS: We tested mRNA levels using quantitative reverse transcription PCR (qRT-PCR). Tissue samples from patients with CRC, inflammatory bowel disease (IBD), hyperplastic polyp, and adenoma were included. Correlations between clinicopathological parameters, overall survival (OS) rate, and LINC01234 were analyzed using Kruskal-Wallis H test. Additionally, cell proliferation, apoptosis, and tumor formation in nude mice were tested to investigate the mechanism of LINC01234. Western blotting was used to determine protein levels. RESULTS: LINC01234 expression was significantly upregulated in CRC tissues and CRC cell lines than in non-tumor tissues and normal epithelial cells, respectively. LINC01234 was associated with high tumor stage, larger tumor size, and metastasis. Patients with higher LINC01234 expression showed reduced OS. Cell proliferation was inhibited by LINC01234 knockdown, whereas apoptosis was enhanced. Mice injected with SW480 cells with LINC01234 knockdown displayed decreased tumor volume, weight, and Ki-67 levels compared with those injected with control cells. KLF6 was negatively regulated by LINC01234. Overexpression of KLF6 showed effects similar to those observed following LINC01234 knockdown on cell proliferation and apoptosis. CONCLUSIONS: LINC01234 could be a prognostic biomarker in CRC patients. Upregulation of LINC01234 in CRC promotes tumor development through negative regulation of KLF6.

ABSTRACT

To compare the efficacies of the two techniques of "micro-hemostasis and micro-cutting" with straight bipolar electrocoagulation forceps and traditional clamp-ligation for hemostasia in thyroid surgery. A total of 228 patients who underwent surgical treatment for thyroid neoplasms in our hospital between January 2015 and December 2018 were retrospectively analyzed, including 50 males and 178 females, aged 23-68 years old. Of those, 150 cases as electric knife group received traditional thyroid surgery between January 2015 and December 2018 and 78 cases as bipolar electrocoagulation group received thyroid surgery by using the technique of bipolar electrocoagulation with meticulous anatomy between January 2018 and December 2018. The total operation time, single operation time, intraoperative hemorrhage, postoperative drainage volume on the first day, postoperative hoarseness and hypocalcemia were compared between the two groups. SPSS 16.0 was used to analyze the data. The total operation time and intraoperative hemorrhage in the bipolar electrocoagulation group were significantly lower than those in the electric knife group ((59.33±18.29)min (77.21±25.39)min, (14.83±9.22)ml (36.86±11.80)ml, all 0.01). The single operation time of the bipolar electrocoagulation group was shorter than that of the electric knife group((10.25±6.16) min (20.34±7.24)min, (16.25±7.15)min (35.68±8.25)min, (12.12±5.25)min (20.68±7.26)min, value was 3.948,16.262,8.238, all 0.01).There was no significant difference between the two groups in postoperative drainage volume on the first day (0.05) and the incidence of postoperative hoarseness (0.05), while the incidence of hypocalcemia in the bipolar electrocoagulation group(10.26%) was lower than that in the electric knife group(21.33%,χ(2)=4.353, 0.05). The fine dissection for thyroid operation can be achieved by using straight bipolar electrocoagulation tweezers. The use of "micro-hemostasis" and "micro-cutting" technique with bipolar electrocoagulation tweezers can greatly reduce intraoperative bleeding, operation time and postoperative complication.

ABSTRACT

Objective To analyze the resistance of influenza virus to neuraminidase inhibitors (NAI) in Hebei province during 2018-2019. Methods Virus were collected from the Hebei Influenza Surveillance Network during 2018-2019. A total of 36 confirmed influenza viruses (with 25 H1pdm09 and 11 H3N2) were selected to test resistance to oseltamivir and zanamivi with fluorescence (FL). Results All 36 influenza viruses tested were sensitive to oseltamivir and zanamivir. The median half maximal inhibitory concentration (IC50) for oseltamivir of H1pdm09 and H3N2 were of 0.50 nM (range 0.07-1.14 nM) and 0.25 nM (range 0.09-0.69 nM) respectively, while 0.29 nM (range 0.09-0.85 nM) and 0.87(range 0.17-1.81 nM) for zanamivir, all were within 10 fold IC50 of the reference virus (corresponding type). Conclusion All the tested influenza strains isolated in Hebei province during 2018-2019 were sensitive to NAI.

ABSTRACT

OBJECTIVE: To investigate the feasibility of using 8-hydroxy-2'deoxyguanosine(8-OHdG) in blood and urine samples as biomarkers for the evaluation of human DNA oxidative damage caused by diesel exhaust(DE). METHODS: A convenient sampling method was used to select 56 male workers exposed to DE in a car manufacturing factory as exposure group, and 52 male workers without exposure to DE were selected as the control group.Urine samples and blood samples were collected from workers in the 2 groups 8 hours after work, and the levels of 8-OHdG in urine and plasma were measured by ultra-high performance liquid chromatography tandem mass spectrometer. RESULTS: The median level of urinary 8-OHdG in the exposure group was higher than that of control group(2.54 vs 2.03 μg/g Cr, P<0.05). The median levels of plasma 8-OHdG in the exposure group and control group showed no statistical significance(32.20 vs 31.40 ng/L, P>0.05). CONCLUSION: The urinary 8-OHdG can be used as a biomarker for evaluating the oxidative damage induced by DE exposure.

ABSTRACT

The incidence of prostate cancer is increasing, and inevitably progresses to castration-resistant prostate cancer. Although the treatment is constantly updated, the prognosis is still not optimistic. Because of its unique advantages of effect-enhancing and toxicity-reducing, improving quality of life, and prolonging survival time, Chinese medicine has occupied a very important position in the treatment of castration resistant prostate cancer. This article summarizes the clinical and basic research of traditional Chinese medicine in the treatment of castration-resistant prostate cancer, and provides reference for clinical treatment and basic research.
