OBJECTIVE: To observe the effects of Huatan Xiezhuo Recipe (HTXZR) on fatty liver of rats. METHODS: Forty-eight SD rats were randomly divided into five groups: normal control group, untreated group, Dongbao Gantai Tablet (DBGTT)-treated group, low-dose HTXZR-treated group and high-dose HTXZR-treated group. Fatty liver was induced in the rats by hyperlipid diet and intraperitoneal injection of tetracycline. The pathological changes of liver tissues in rats were observed, and the liver function, serum leptin, insulin resistance index, triglyceride (TG) and free fatty acid (FFA) in the liver were detected. RESULTS: The levels of serum leptin, insulin resistance index, FFA and TG in rats of the three treated groups were lower than those of the untreated group (P<0.01), and such effects in the HTXZR-treated groups were more significant than those in the DBGTT-treated group (P<0.05). CONCLUSION: The main action mechanisms of HTXZR in treating fatty liver are probably to promote the lipid metabolism, decrease the leptin and insulin resistance.

A field demonstration of reduction of lead availability in a soil and cabbage (Brassica Chinensis L.) contaminated by mining tailings, located in Shaoxing, China was carried out to evaluate the effects of applications of phosphorus fertilizers on Pb fractionation and Pb phyto-availability in the soil. It was found that the addition of all three P fertilizers including single super phosphate (SSP), phosphate rock (PR), and calcium magnesium phosphate (CMP) significantly decreased the percentage of water-soluble and exchangeable (WE) soil Pb and then reduced the uptake of Pb, Cd, and Zn by the cabbage compared to the control (CK). The results showed that the level of 300 g P/m(2) soil was the most cost-effective application rate of P fertilizers for reducing Pb availability at the first stage of remediation, and that at this P level, the effect of WE fraction of Pb in the soil decreased by three phosphorus fertilizers followed the order: CMP (79%)>SSP (41%)>PR (23%); Effectiveness on the reduction of Pb uptake by cabbage was in the order: CMP (53%)>SSP (41%)>PR (30%). Therefore our field trial demonstrated that it was effective and feasible to reduce Pb availability in soil and cabbage contaminated by mining tailings using P fertilizers in China and PR would be a most cost-effective amendment.

Objective:Iron accumulation is related to the occurrence of postmenopausal osteoporosis. Meanwhile, autophagy abnormality of bone marrow hematopoietic cells is observed in hip osteoporotic fracture. This study is performed to investigate correlation between iron accumulation induced bone loss and hematopoietic autophagy dysfunction to explore the new risk factor of osteoporosis.Methods:Male iron accumulation mice model was established by intraperitoneally injecting ferric ammonium citrate. Serum ferritin and osteogenic indicator P1NP were tested by ELISA. Bone mineral density was measured by micro-CT. Femur and tibia bone marrows were collected for hematopoietic stem and progenitor cells proportion and cell apoptosis analysis. Autolysosome formation was measured by image flow cytometry. We used conditional mouse model Atg7 flox/flox; Vav-Cre(Atg7 -/-) in which Atg7 had been genetically deleted in the hematopoietic system. Bone marrow hematopoietic stem and progenitor cells were collected for RNA sequence. micro-CT scan was conducted for Atg7 -/- femur. Results:Ferritin level of iron accumulation mice was significantly higher than control group( P<0.05). Iron accumulation inhibited P1NP and induced decreased bone mineral density( P<0.05). Iron accumulation bone marrow displayed enhanced hematopoietic stem and progenitor cells proportion( P<0.05), with more cell apoptosis( P<0.05). Hematopoietic autophagy was deteriorated in iron accumulation bone marrow. Transcriptomic profiling showed up-regulation of iron activity in Atg7 -/- mice, with increased iron homeostasis and iron membrane transporter genes, including Lcn2, Tfr2, Slc40a1(Fpn1), Steap3, and Cpox. micro-CT revealed severe bone loss and decreased bone mineral density in Atg7 -/- mice( P<0.05). Conclusion:Iron accumulation induced bone loss is related to inhibition of hematopoietic cells. Hematopoietic autophagy dysfunction is associated with bone loss.

Objective To identify related factors for hypoglycemic episodes in patients with type 2 diabetes mellitus(T2DM)through continuous glucose monitoring(CGM). Methods The included 147 patients with T2DM were those who had undergone CGM for 5 days in our ward of Department of Endocrinology and Metabolism,Huashan Hospital from Dec 2018 to Oct 2019. The general information, laboratory parameters and CGM parameters of the patients were collected. According to whether there wasan episode of hypoglycemia during the monitoring period,the patients were divided into non-hypoglycemia group and hypoglycemic group. A single hypoglycemia episode was defined as a sensor monitoring blood glucose of less than 3.9 mmol/L and lasting for more than 15 minutes.CGM parameters included the mean blood glucose(MBG),standard deviation(SD),coefficient of variation(CV),the differences between maximum and minimum blood glucose (BG) levels (ΔBG),mean amplitude of glycemic excursions (MAGE)and the percentage of time in range(%TIR)of BG at <3.9 mmol/L,3.9-7.8 mmol/L,>7.8 mmol/L,3.9-10.0 mmol/L,and >10.0 mmol/L. Results Logistic regression analysis showed that lower estimated glomerular filtration rate(eGFR)levels,increased use of insulin and its analogs and lower MBG levels were associated with hypoglycemic episodes. Spearman correlation analysis showed that the MBG level and the %TIR of BG>7.8 mmol/L and BG>10.0 mmol/L were negatively associated while glycemic variability(GV)levels(SD,CV,ΔBG,MAGE)and % TIR of BG at 3.9-7.8 mmol/L were positively associated with hypoglycemic episodes. Pearson correlation analysis showed that the duration of hypoglycemic episodes was positively correlated with the use of sulfonylureas and CV levels. Conclusion Lower eGFR levels,increased treatment with insulin and its analogs and lower MBG levels were related factors for hypoglycemic episodes in patients with T2DM.

Objectives:To explore changes in the quality of life(QoL)in patients with non-severe aplastic anemia(NSAA)after 2 years of cyclosporine A(CsA)therapy, and possible factors may affect the QoL.Methods:Patients with de novo NSAA from January 2014 to 2016 who had been treated with only CsA for at least 2 years in the outpatient department of Peking Union Medical College Hospital were instructed to fill-in the SF-36 form before and after 2 years of CsA treatment. Data from NSAA were compared with those of normal controls; patients’ information such as age, sex, education, annual income, type of payment, and compliance were collected, disease severity and response to treatment were also evaluated.Results:A total of 52 patients were included in our study with 27(51.9%)men and 25(48.1%)women, with the medium age of 48(21-85)years. After 2 years of treatment, 15(28.8%)patients achieved complete response(CR), 25(48.1%)achieved partial response(PR), and 12(23.1%)patients had no response(NR). The overall response rate(ORR)was 76.9%. Before the therapy, SF-36 scores in patients with NSAA were significantly lower than that of normal controls either in physical or mental component summaries( P<0.05). However, after 2 years of therapy, patients with NSAA had significant improvement of mental component summaries and recovered to normal with even higher scores in mental health(MH)(65.9±17.6 vs 59.7±22.9, P=0.014)and energy/vitality(VT)(58.8±20.1 vs 52.3±20.9, P=0.023)compared with normal controls, although they still had comparatively lower scores in physical component summaries. No associations were found between QoL and age, sex, educational level, family income, type of payment, patient adherence, or transfusion dependency. Patients with higher ECOG (the Eastern Cooperative Oncology Group score)at the beginning experienced greater progress in QoL compared to those with lower ECOG. Both patients with CR and PR had shown significant improvement in QoL. Conclusion:Patients with NSAA had impaired QoL compared with normal patients. CsA treatment can improve the QoL, especially in mental component summaries. Patients can benefit from the treatment regardless of their social status, and patients with lower ECOG at the beginning seem to benefit more from the therapy.

OBJECTIVETo summarize the experiences in high-risk renal transplant recipients for ketter long-term survival.
METHODSFrom April 1991 to December 2008, a total of 921 kidney recipients with high-risk factors were divided into six groups as following: (1) pediatric patients (< 18 years old) (GI, n = 34); (2) retransplant recipients (GII, n = 169); (3) high sensitized patients (PRA> 30% or peak PRA > 50%)(GIII, n = 35); (4) elderly recipients (> 60 years old) (GIV, n = 297); (5) diabetic patients (GV, n = 112); (6) patients with HBV/HCV infection or HBV/HCV carrier (GVI, n = 274). Each group was compared to a control of 807 recipients without any above risk factor for patient and graft survival at 1, 3 and 5 years. Incidences of acute rejection (AR), chronic rejection (CR) and complication were analyzed and compared respectively between the studied subjects and the control group as well.
RESULTSCompared with the control group, patient/graft survivals were lower in GII, GIII and GVI (all P < 0.05), GIV had worse patient survival (P < 0.05); AR and CR incidences were greater in GI and GIII (all P < 0.05); GIV, GV and GVI had more complications.
CONCLUSIONSThis study suggests the benefits for long-term outcome in high-immunological risk renal transplant recipients of low acute selection incidence rate, and reduction of complication incidences is the key to long term results for non-immunological high risk recipients.

miR-34a is a conserved microRNA highly expressed in the brain. It is thought to play critical roles in regulating many aspects of brain development and function, such as neural stem cell proliferation and differentiation, neuronal migration and apoptosis, fear memory consolidation, etc. However, the assessment of its function was mainly conducted through vector-mediated overexpression and miRNA sponge or antagomir-mediated functional suppression, therefore may suffer from nonspecific off-target effects or incomplete inactivation. We thus analyzed mouse model with a targeted deletion of miR-34a which completely abolishes its expression. To our surprise, loss of miR-34a led to neither an obvious change in brain size, morphology or cortical lamination, nor impaired marker gene expression in major excitatory and inhibitory neuron types in the neocortex. In addition, miR-34a ablation did not affect fear memory formation or consolidation, as well as the anxiety or depression related behavior. However, the performance of mice in rotarod assay was significantly affected, suggesting a defect in motor activity in miR-34a deficient mice. As neocortical parvalbumin (PV) neurons are known for high level miR-34a expression, we also tested the effect of PV-Cre-mediated conditional miR-34a deletion. Similar as germline deletion, PV neuron specific miR-34a deletion did not affect cortical lamination or PV expression in the neocortex. Our studies suggest that, although miR-34a may be involved in regulating certain aspects of brain development or function, such as motor activity, it does not play a significant role in regulating brain morphogenesis, cortical lamination or neocortical neuron subtype specification, and it is also dispensable for fear memory formation, expression and consolidation.

OBJECTIVETo investigate the factors associated with the occurrence of transplant renal artery stenosis (TRAS).
METHODSA retrospective analysis was conducted in 26 recipients who developed TRAS and 40 concurrent renal recipients without TRAS. We also conducted a nested case-control study in 14 patients with TRAS (TRAS-SD group) and another 14 non-TRAS recipients who received the allograft from the same donor (non-TRAS-SD group).
RESULTSCompared with those in the concurrent recipients without TRAS, acute rejection (AR) occurred at a significantly higher incidence (P=0.004) and the warm ischemia time (WIT) was significantly longer (P=0.015) and the level of high?density lipoprotein cholesterol (HDL--C) significantly lower (P=0.009) in the recipients with TRAS. Logistic regression analysis suggested that AR (P=0.007) and prolonged WIT (P=0.046) were risk factors of TRAS while HDL-C (P=0.022) was the protective factor against TRAS. In recent years early diagnosis of TRAS had been made in increasing cases, the interval from transplantation to TRAS diagnosis became shortened steadily, and the recipients tended to have higher estimated glomerular filtration rate at the time of TRAS diagnosis.
CONCLUSIONApart from the surgical technique, AR and prolonged WIT are also risk factors of TRAS while a high HDL-C level is the protective factor against TRAS. The improvement of the diagnostic accuracy by ultrasound is the primary factor contributing to the increased rate of early TRAS diagnosis in recent years.
