ObjectiveTo investigate the clinical efficacy of Huangqi injection combined with Buzhong Yiqi acupuncture in the treatment of chronic fatigue syndrome （CFS） with Qi deficiency and its effects on TCM syndromes， fatigue symptoms， serum superoxide dismutase （SOD）， malondialdehyde （MDA）， and oxidized low-density lipoprotein （ox-LDL） levels. MethodA total of 200 patients with CFS of Qi deficiency were randomly divided into a control group （100 cases） and an observation group （100 cases）. The control group was treated with vitamin B compounds， and the observation group was treated with Huangqi injection combined with Buzhong Yiqi acupuncture for two weeks. The scores of TCM syndromes， fatigue symptoms， levels of serum SOD， MDA， and ox-LDL and the incidence of adverse reactions were observed and compared before and after treatment in two groups. ResultAfter treatment， the total effective rate of the control group was 54.34% （50/92）， while that of the observation group was 88.54% （85/96）. The total effective rate of the observation group was higher than that of the control group （χ²=27.13，P<0.05）. Compared with those in the two groups before treatment， scores of fatigue self-assessment scale （FSAS）， physical fatigue and mental fatigue， and sleep/rest response scores of fatigue in the two groups after treatment were significantly decreased （P<0.05）. After treatment， scores of FSAS， physical fatigue and mental fatigue， and sleep/rest response scores of fatigue in the observation group were significantly decreased compared with those in the control group （P<0.05）. Compared with those in the two groups before treatment， TCM syndrome scores in the two groups after treatment were significantly decreased （P<0.05）. After treatment， TCM syndrome scores in the observation group were significantly decreased compared with those in the control group （P<0.05）. Compared with those in the two groups before treatment， MDA levels in the two groups were significantly decreased （P<0.05）， ox-LDL levels in the observation group were significantly decreased （P<0.05）， and SOD levels were significantly increased （P<0.05）. After treatment， compared with those in the control group， the serum MDA and ox-LDL levels in the observation group were significantly decreased （P<0.05）， and the serum SOD was significantly increased （P<0.05）. No serious adverse events or adverse reactions occurred during this clinical trial. ConclusionHuangqi injection combined with Buzhong Yiqi acupuncture has a good clinical curative effect in the treatment of CFS with Qi deficiency， which can effectively improve the fatigue symptoms of patients， increase the level of SOD， and reduce the level of serum MDA and ox-LDL. It is related to the production of antioxidants， inhibiting the production of lipid peroxides， and improving the body's ability to resist oxidative stress.

【Objective】 To analyze the characteristics and mobility of the overlapping population of voluntary blood donation and plasmapheresis donation, so as to provide a scientific basis for the formulation of recruitment and retention strategies for blood donation and plasmapheresis donation, and to further propose a scientific reference for the decision-making of blood banks and plasmapheresis station management in China. 【Methods】 The basic information of blood donors and plasmapheresis donors in two counties in Guangyuan, Sichuan Province, which carried out whole blood collection and plasmapheresis collection from the establishment of the station to July 31, 2021 was statistically compared and analzed using the chi-square test and Post hoc testing test. 【Results】 As of July 31, 2021, a total of 50 658 people participated in blood donation and 63 375 people participated in plasmapheresis donation in Jiange County and Cangxi County, with a total overlap of 6 189 people. In the two regions, 16 458 (35.2%) people aged 40 to 50, and 35 558 people (56.1%) were over 50 years old. Among the overlapping population, 2 496 (40.3%) were 40 to 50 years old, accounted for the largest proportion, and 3 146 (50.8%) were males. Significant differences were noticed in age (P<0.001) and gender (P<0.001). There was a shift in dontion in 5 183, including 2 072 people from plasma to blood and 3 111 people from blood to plasma, among which 2 671 (51.5%) were men and 3 632 (70.1%) were over 50 years old, with significant differences in gender (P<0.05) and age (P<0.001). 【Conclusion】 There were a small number of donors donating both blood and plasma in Jiange and Cangxi, and men aged 40 to 50 were the majority, and people over 50 years old were more likely to shift the donation goals. The vast majority of donors have a single and fixed donation goal (blood or plasma), and are not easy to change.

【Objective】 To analyze the dynamic relationship between the setting up of plasmapheresis station and the volume of voluntary blood donation collected using panel vector autoregressive model, so as to provide scientific reference for the management policies of blood stations and plasmapheresis stations in China. 【Methods】 The data collected from blood stations in seven administrative regions of Guangyuan, Sichuan Province from 2011 to 2021, as well as plasma collection data from two plasmapheresis stations in the region within two years since their operation, were collected. A panel vector autoregressive model was constructed. Impulse response analysis and variance decomposition analysis were used to analyze the impact and time lag effects of simulated plasmapheresis station settings on the collection volume of voluntary blood donation. Covariance analysis was used to explore whether the establishment of plasmapheresis station had an impact on the volume of voluntary blood donation collected after excluding the impact of initial value differences. 【Results】 The pulse response results showed that after the plasmapheresis station was set up, there was a negative impact effect on the voluntary blood donation collection volume at the first stage, and its impact began to rise after the second stage, reached the highest value in the third stage, and then began to decline. After the seventh stage, it tended to be stable. However, within the 10 stage range, the confidence interval for the response strength of voluntary blood donation collection volume always included 0, indicating that the response of blood collection volume to the plasmapheresis station setting in the region was not statistically significant. The results of variance decomposition showed that the contribution of collection volume of voluntary blood donation to their own impact reached 94.3%. In terms of the contribution of plasmapheresis station factors, the number of plasma donors has a relatively greater impact on the volume of voluntary blood donation collected(2.2%). Covariance analysis showed that after removing the initial confounding factors, whether to establish a plasmapheresis station had no significant impact on blood donation volume in the two groups of regions (P>0.05). 【Conclusion】 The establishment of a new plasmapheresis station will have a certain impact on blood collection volume of blood stations in the region in a short term, but in the long term, it may not directly affect the voluntary blood donation collection in the region.

【Objective】 To explore the difference of demographics and influencing factors of motivations between whole blood donors and plasmapheresis donors, so as to provide scientific reference for effective recruitment strategy. 【Methods】 A total of 200 whole blood donors from Guangyuan Blood Center and 200 plasmapheresis donors from Jiange Plasmapheresis Station were selected in August 2021 for on-site questionnaire survey using the method of cross-sectional survey. Statistical analysis was performed by chi-square test, univariate and multivariate logistic regression. 【Results】 There were significant differences in gender, age, occupation, education level and annual family income between whole blood donors and plasmapheresis donors (P<0.05). Males accounted for a large proportion of whole blood donors(124/196, 63.3%), whereas females accounted for a large proportion of plasmapheresis donors(117/198, 59.1%). There was little difference in the number of whole blood donors in different age groups, while the age of plasmapheresis donors was concentrated in 40~59 years old (167/198, 84.3%). In terms of occupation, civil servants (including public institutions) accounted the highest proportion in whole blood donors (41/196, 20.9%), and farmers accounted the highest proportion (152/198, 76.8%) in plasmapheresis donors. The number of whole blood donors increased with the education level, and donors with college/university and above degree accounted the largest proportion (80/196, 40.8%). Plasmapheresis donors with junior middle school education and college/university and above accounted the largest and smallest proportion (49.5% vs 4.5%). The annual family income of whole blood donors ranged from 30 000 to 80 000 yuan accounted the largest proportion (109/196, 55.6%), and the annual family income of plasmapheresis donors less than 30 000 yuan accounted the largest proportion (132/198, 66.7%). 【Conclusion】 There were significant statistical differences in gender, age, education level, occupation and annual family income between whole blood and plasmapheresis donors. Therefore, targeted recruitment strategies should be formulated.

Objective:To explore the feasibility and safety of robot-assisted retrohepatic inferior vena cava(IVC) tumor thrombectomy for renal tumor patients with a single position.Methods:The clinical data of 6 renal tumor patients with retrohepatic IVC thrombus (5 males and 1 female, mean age of 58 years) who underwent robot-assisted retrohepatic IVC tumor thrombectomy with a single position in First Affiliated Hospital of Zhengzhou University from December 2015 to August 2020 were retrospectively reviewed. Four cases had the renal tumor on the right side and two on the left side. The mean tumor size was 9.6 cm(range 7-13 cm). There were 4 cases of Mayo level Ⅱ and 2 cases of level Ⅲ IVC thrombus with the mean IVC thrombus length of 6.5 cm(range 5-8cm). The "IVC-first, kidney-last" robotic technique was developed to minimize chances of IVC thrombus embolization for retrohepatic IVC thrombus, and a "artery-first, vein-second" robotic operative strategy were developed to minimize chances of intraoperative hemorrhage. The whole procedure (the suprahepatic infradiaphramatic IVC, first porta hepatis and left renal vein control, caval exclusion, tumor thrombectomy, IVC repair, radical nephrectomy) was performed exclusively robotically with a single position.Results:All 6 robotic procedures were successful, without open conversion or mortality. The mean operative time was 210 min(130-320 min), estimated blood loss was 800 ml(300-2 100 ml) and three patients (5%) received intraoperative blood transfusion. The mean time of occlusion of IVC was 21 min (15-43min). Incomplete blocking occurred in two cases(one IVC, one first porta hepatis), and tumor thrombectomy were completed with intraoperative loss. IVC invasion was confirmed intraoperatively in one patient and we staple-transected the IVC without reconstruction. Six patients were all transferred to the intensive care unit for median of 2.1 days (1-4 days) after surgery. The mean time of postoperative drainage was 5 days (4-9 days). Renal dysfunction occurred in 3 patients and liver dysfunction occurred in 2 patients, and all recovered after medical therapy. Postoperative pathological diagnosis revealed 5 cases of clear cell carcinoma and 1 case of renal sarcoma, and the 5 cases received targeted therapy. With a median follow-up of 27 months (3-54 months), 3 patients were alive, 1 alive with tumor recurrence, and 2 died of cancer.Conclusions:Robot-assisted laparoscopic retrohepatic IVC thrombectomy with a single position have the advantage of simple procedure, shorter operative time, less trauma and quicker recovery, and it is a feasible and effective method for renal tumor patients with retrohepatic IVC thrombus.

Objective:To evaluate the recovery of daytime and nighttime urinary continence in patients with robotic-assisted radical cystectomy and ileal orthotopic neobladder from 1 to 60 months after surgery, and systematically analyze the influencing factors of daytime and nighttime urinary continence recovery.Methods:The convenient sampling method was used to select clinical data of 60 patients who underwent robotic-assisted radical cystectomy and ileal orthotopic neobladder by a single operator from December 2014 to January 2020 and they were followed up for daytime and nighttime use of urine pads and prognosis. A total of 44 patients were eligible for follow-up data. Satisfactory recovery of daytime and nighttime urinary continence was defined as the use of less than or equal to 1 pad, and complete recovery of daytime and nighttime urinary continence was defined as no urine leakage. The daytime and nighttime urinary continence recovery in patients with robotic-assisted radical cystectomy and ileal orthotopic neobladder was assessed at 1, 3, 6, 12, 24, 36, and 60 months. Cox regression was used to analyze the influencing factors of postoperative urinary continence recovery.Results:Cox regression multivariate analysis showed that preservation of neurovascular bundles was associated with satisfactory recovery of daytime urinary continence, satisfactory recovery of nighttime urinary continence and complete recovery of daytime urinary continence ( P<0.05) . Clevien grading of complications within 90 d could affect the satisfaction of daytime urinary control recovery. Preoperative hydronephrosis was an independent factor affecting the satisfaction of nighttime urinary continence recovery. Conclusions:Preserving neurovascular bundles is an influencing factor in promoting postoperative urinary continence recovery in patients with robotic-assisted radical cystectomy and ileal orthotopic neobladder. In addition, postoperative complications and preoperative hydronephrosis are independent factors affecting the satisfaction of daytime and nighttime urinary continence recovery, respectively, but it need to be further confirmed by multicenter prospective studies.

Adrenal cortical adenocarcinoma is a rare and often aggressive malignant tumor. For ACC that originated outside the adrenal gland, there are few reports at home and abroad. We report a case of adrenocortical adenocarcinoma that originated from kidney, introduce its diagnosis, treatment and follow-up results in order to provide help for clinical diagnosis and treatment.

HuR (human antigen R), an mRNA-binding protein responsible for poor prognosis in nearly all kinds of malignancies, is a potential anti-tumor target for drug development. While screening HuR inhibitors with a fluorescence polarization (FP) based high-throughput screening (HTS) system, the clinically used drug eltrombopag was identified. Activity of eltrombopag on molecular level was verified with FP, electrophoretic mobility shift assay (EMSA), simulation docking and surface plasmon resonance (SPR). Further, we showed that eltrombopag inhibited cell proliferation of multiple cancer cell lines and macrophages, and the anti-tumor activity was also demonstrated in a 4T1 tumor-bearing mouse model. The data showed that eltrombopag was efficient in reducing microvessels in tumor tissues. We then confirmed the HuR-dependent anti-angiogenesis effect of eltrombopag in 4T1 cells and RAW264.7 macrophages with qRT-PCR, HuR-overexpression and HuR-silencing assays, RNA stability assays, RNA immunoprecipitation and luciferase assays. Finally, we analyzed the anti-angiogenesis effect of eltrombopag on human umbilical vein endothelial cells (HUVECs) mediated by macrophages with cell scratch assay and Matrigel angiogenesis assay. With these data, we revealed the HuR-dependent anti-angiogenesis effect of eltrombopag in breast tumor, suggesting that the existing drug eltrombopag may be used as an anti-cancer drug.

Total hip replacement (THR) is replacing the prosthesis stem similar to human bone that takes advantage of the material with both good mechanical properties and biocompatibility to the damaged articular surface. Thus it can not only alleviate or even eliminate the pain but also effectively maintain the joint stability and freedom and restore its normal performance. Finite element analysis was used in this study to establish a 3D model of artificial hip stem, and explore its fatigue properties of different materials to ensure the safety and reliability. The calculating obtained two results of different metal hip prosthesis, including lifetime and deformation. The minimum service life of titanium prosthesis reaches 568 million times, which satisfies ISO standards, while the stainless steel does not suit to be a prosthesis material.
