OBJECTIVE: To investigate the inflammatory effects of Cinobufotalin on monocytes in resting state and macrophages in activated state and its molecular mechanism. METHODS: THP-1 cells were stimulated with Phorbol 12-myristate 13-acetate to induce differentiation into macrophages. Lipopolysaccharides was added to activate macrophages in order to establish macrophage activation model. Cinobufotalin was added to the inflammatory cell model for 24 h as a treatment. CCK-8 was used to detect cell proliferation, Annexin V /PI double staining flow cytometry was used to detect cell apoptosis, flow cytometry was used to detect macrophage activation, and cytometric bead array was used to detect cytokines. Transcriptome sequencing was used to explore the gene expression profile regulated by Cinobufotalin. Changes in the significantly regulated molecules were verified by real-time quantitative polymerase chain reaction and Western blot. RESULTS: 1∶25 concentration of Cinobufotalin significantly inhibited the proliferation of resting monocytes(P<0.01), and induced apoptosis(P<0.01), especially the activated macrophages(P<0.001, P<0.001). Cinobufotalin significantly inhibited the activation of macrophages, and significantly down-regulated the inflammatory cytokines(IL-6, TNF-α, IL-1β, IL-8) released by activated macrophages(P＜0.001). Its mechanism was achieved by inhibiting TLR4/MYD88/P-IκBa signaling pathway. CONCLUSION Cinobufotalin can inhibit the inflammatory factors produced by the over-activation of macrophages through TLR4/MYD88/P-IκBa pathway, which is expected to be applied to the treatment and research of diseases related to the over-release of inflammatory factors.

OBJECTIVE: To compare the effects of direct fluorescence in situ hybridization (D-FISH) detection without sorting and CD138 immunomagnetic bead sorting technology combined with FISH (MACS-FISH) on cytogenetic analysis of patients with multiple myeloma (MM). METHODS: FISH test results of 229 patients with initial MM were retrospectively analyzed. The patients were divided into two groups, 140 patients were tested with D-FISH and 89 patients with MACS-FISH. The combination probe was designed as P53, D13S319, RB1, 1q21, and IgH. Cytogenetic detection results were compared between the two groups. RESULTS: The total detection rate of cytogenetic abnormalities in D-FISH group was 52.9%, and that in MACS-FISH group was 79.8%. There was a significant difference in the cytogenetic abnormality rate between the two groups (P=0.020). The abnormal genes with the highest detection rate in the two groups were 1q21 and IgH, respectively, while the lowest was P53. There was no significant difference in the percentage of P53 positive cells (positive rate) between the two groups, while D13S319, RB1, 1q21, and IgH showed significant difference in positive cell rate (P=0.0002, P<0.0001, P=0.0033, P=0.0032). There was no significant correlation between the proportion of plasma cells (PC) detected by bone marrow morphology and cytogenetic abnormality rate in the D-FISH group, while there was a correlation between the proportion of PC detected by flow cytometry and cytogenetic abnormality rate (r=0.364). The PC proportion detected by bone marrow morphology and flow cytometry in the MACS-FISH group had no correlation with the cytogenetic abnormality rate and positive cell rate of the 5 genes mentioned above. Additionally, the PC proportion detected by bone marrow morphology and flow cytometry showed significant difference (P<0.0001). CONCLUSION CD138 immunomagnetic bead sorting combined with FISH technology can significantly improve the abnormality detection rate of MM cytogenetics.

The randomized controlled trials about modified Sangbaipi Decoction in the treatment of acute exacerbation of chronic obstructive pulmonary disease( AECOPD) patients were collected from 7 databases( PubMed,CNKI,et al) from the establishment to December 5,2018. All the studies searched were strictly evaluated. Literatures were independently screened by two researchers according to the inclusion and exclusion criteria,and the methodological quality of included studies was evaluated. To systematically review the efficacy of modified Sangbaipi Decoction in treating AECOPD,the Meta-analysis and trial sequential analysis were conducted by using Stata/SE 14. 0 and TSA 0. 9. 5. 10 Beta,respectively. A total of 25 RCTs involving 1 784 patients were included. According to the results of Meta-analysis,compared with the control groups,the trial group had a higher clinical efficacy in AECOPD patients( RR =1. 18,95%CI[1. 13,1. 22],P = 0),improved pulmonary functions including forced expiratory volume in one second( FEV1,WMD =0. 44,95%CI[0. 01,0. 87],P = 0. 046),and the forced vital capacity( FVC,WMD = 0. 42,95%CI[0. 07,0. 22],P = 0),but no statistical significance in the percentage of forced expiratory volume in one second( FEV1%,P = 0. 067) and the first seconds breathing volume percentage of forced vital capacity( FEV1/FVC,P = 0. 238); it improved the arterial oxygen partial pressure( PaO2,SMD =0. 85,95%CI[0. 41,1. 30],P = 0) and decreased the arterial partial pressure of carbon dioxide( PaCO2,SMD =-0. 94,95% CI[-1. 70,-0. 18],P= 0. 016); and in terms of inflammatory markers,it improved the white blood cell count( WBC,WMD=-0. 94,95%CI[-1. 17,-0. 70],P = 0). The trial sequential analysis showed that the studies included with the improvement of clinical efficacy had passed the conventional and TSA threshold,so as to further confirm the evidence. According to the findings,in addition to conventional Western medicine treatment,modified Sangbaipi Decoction could improve the efficiency in treating acute exacerbation patients with chronic obstructive pulmonary disease,increase PaO2,and decrease PaCO2,with a high safety but no effect on pulmonary function. However,restricted by the low quality of studies included,this conclusion shall be further verified by more high-quality clinical trials.

OBJECTIVETo investigate the relationship between hypertriglyceridemic waist to height ratio phenotype (HWHtR) and chronic kidney disease (CKD) in a community population in South China.

METHODSA cross sectional study was conducted among 2142 residents in Zhuhai (Guangdong Province, China) from June to October of 2012. The HWHtR phenotype was defined as a waist to height ratio(WHtR) ≥0.55 and triglyceride level ≥2.0 mmol/L, based on which the participants were divided into HWHtR group and nonHWHtR group. CKD was defined as an eGFR<60 mL/min per 1.73 m2 or an ACR ≥30 mg/g. A logistic regression model was established to investigate the relationship between chronic kidney disease and HWHtR phenotype.

RESULTSCompared with the nonHWHtR group, the HWHtR group had a higher prevalence of chronic kidney disease (11.1% vs 33%, P<0.001). Analysis using the logistic regression model showed that HWHtR was significantly associated with CKD in the unadjusted analyses (OR=3.23, 95% CI: 2.32-4.48, P<0.001). After adjustment for age, sex, history of hypertension, history of diabetes, systolic blood pressure, diastolic blood pressure, drinking, physical exercise, education and current smoking, HWHtR was significantly associated with CKD (OR=2.36, 95% CI: 1.52-3.67, P<0.001); the association of HWHtR and CKD was still significant after further adjustment for BMI (OR=2.12, 95%CI: 1.34-3.35, P<0.001).

CONCLUSIONOur finding suggests that HWHtR is associated with CKD in this community population.

OBJECTIVETo investigate the clinical efficacy of Fu Fan Huang Dai Pian(RIF) and arsenic trioxide (ATO) regimens for treatment of children with acute promyelocytic leukemia (APL) and to explore the risk factors affecting the prognosis of patients.

METHODSThe clinical data of 45 newly diagnosed APL children admitted in our hospital from January 2004 to May 2017 were analyzed retrospectively. Among 45 APL children, 25 children were treated by chemotherapetic regimen including RIF (RIF group), another 20 children were treated by chemotherapeutic regimen including ATO (ATO group). The follow-up was performed in all APL children. The prognosis and incidence of side reactions from drugs in 2 groups were compared, and the high risk factors affecting the prognosis of patients were analyzed.

RESULTSThe median follow-up time was 49.8% months. In RIF group, no early death occured in 25 APL children; 5 cases did not achieve complete remission (CR) after induction therapy, CR rate was 88%. Out of 25 cases 2 caes relapsed, 3 cases died, 20 cases maintained contined CR (CCR), 2 cases failed to be followed-up. In ATO group, 2 cases suffered from early death, 5 cases did not achieve CR after induction therapy, CR rate was 90%, 2 caese relapsed and died, 15 cases maintained CCR, the follow-up failed in 1 caes. The 5 year- OS and EFS rate in all the patients were predicted as (82.2±6.2)% and (76.4±6.6)% respectively. The OS and EFS rate in RIF group were (86.1±7.4)% and (78.4±8.6)% respectively, which were significantly different from OS and EFS rate (76.4%±10.6%) and (74.0%±10.1%) respectively in ATO group (all P>0.05). As for the side reaction from drug, except for the cardiac damage (P<0.05), incidence of other side reactions was not significantly different between 2 groups (P>0.05). In addition, the 5 year-OS and EFS rates in APL children with CNSL were significantly lower than those in APL children without CNSL (all P<0.05), the 5 year OS and EFS rate in APL children did not reache M1 and with high risk were significantly lower than those in APL children reached M1 after induction therapy and with low and standerd risk (P<0.05 and P<0.05); the 5 year-OS and EFS rates did not correlate with age and sex.

CONCLUSIONThe Fu Fang Huang Dai Pian shows the therapeutic efficacy on APL children same as ATO, moreover, no obvious enhancement in incidence of side reactions is observed, therefore, the Fu Fang Huang Dai Pian is effective and safe for treatment of APL children. The CNSL, poor respond to treatment, high risk in clinical stratification are high risk factors affecting prognosis of patients.

OBJECTIVETo compare the safety, efficacy and complications of laparoscopic pyelolithotomy (LPL) and percutaneous nephrolithotomy (PCNL) for treatment of renal pelvic stones larger than 2.5 cm.

METHODSFrom 2011 to 2016, 32 patients underwent LPL and another 32 patients received PCNL for renal pelvic stones larger than 2.5 cm. The baseline characteristics of the patients, stone size, mean operative time, estimated blood loss, postoperative hospital stay, stone-free rate, postoperative analgesia, blood transfusion, and the intraoperative, early postoperative and long-term complications were compared between the two groups.

RESULTSThe baseline characteristics and stone size were comparable between the two groups. The mean operative time of LPL and PCNL was 117∓23.12 and 118.16∓25.45 min, respectively (P>0.05). The two groups showed significant differences in the mean estimated blood loss (63∓11.25 vs 122∓27.78 mL, P<0.01) and blood transfusion rate (0 vs 6.2%, P<0.01) but not in postoperative hospital stay (4.5∓1.34 vs 4.8∓2.2 days, P>0.05), stone-free rate (93.1% vs 87.5%, P>0.05) or the postoperative analgesia time (1.7∓0.5 and 1.9∓0.6 days, P>0.05). The incidence of intraoperative complications were significant lower in LPL group than in PCNL group (6.2% vs 25.0%, P<0.01), but the incidences of early postoperative complications (25.0% vs 34.4%, P>0.05) and long-term postoperative complications (9.4% vs 12.5%, P>0.05) were similar between them.

CONCLUSIONPCNL is the standard treatment for pelvic stones larger than 2.5 cm, but for urologists experienced with laparoscopic technique, LPL provides a feasible and safe option for management of such cases.

OBJECTIVETo observe the pathological changes in rabbits with spinal cord injury induced by decompression sickness (DCS), and to investigate the role of tumor necrosis factor-alpha (TNF-α) in spinal cord injury induced by DCS.

METHODSRabbits were randomly divided into normal control group, DCS group, and safe decompression group. The rabbit model of DCS was established. Light microscopy, real-time PCR, and immunohistochemical method were used to observe the pathomorphological changes in the thoracolumbar spinal cord and the mRNA and protein expression of TNF-α, respectively. The terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) was used to observe the apoptosis in the spinal cord.

RESULTSIn the DCS group, cavities formed in the white matter of spinal cord and gliosis occurred around necrotic areas. Moreover, the mRNA and protein expression of TNF-α was significantly higher in the DCS group than in the normal control group and the safe decompression group (P<0.01). The results of TUNEL showed that the number of positive apoptotic cells was significantly larger in the DCS group than in the normal control group and the safe decompression group (P<0.05).

CONCLUSIONApoptosis plays an important role in spinal cord injury induced by DCS. In the early stage of DCS, the massive release of TNF-α initiates apoptosis and contributes to the pathological changes in spinal cord injury induced by DCS.
