Objective To study and summarize the ECG characteristics of monomorphic premature ventricular contraction(PVC) originating from different sites， and to evaluate their clinical value on determining the pacing target in catheter radiofrequency ablation. Methods We randomly selected 53 PVC patients as research subjects who had been admitted in Peking University People's Hospital from January to November 2017. All the patients underwent catheter radiofrequency ablation. Preoperative ECG features were analyzed which served for the selection of pacing target in catheter radiofrequency ablation. The surgical efficacy and occurrence of complications were observed. Results Among the 53 PVC patients, 50 case(94.34%) were successfully ablated among whom the origins of PVC were correctly identified by ECG in 48 patients(96%). There were 19 cases (35.85%) of PVC originating from the left ventricle and 31(58.49%) originating from the right ventricle. In the 50 successfully-ablated patients, no recurrence was reported during the follow-up of over 3 months. Due to various causes, 3 patients endured surgical failure, accounting for about 5.66%. Conclusion The ECG characteristics of monomorphic PVC help identify the ablation target in advance and reduce the operation time. Catheter radiofrequency ablation is safe and effective for treating frequent monomorphic PVC. [ABSTRACT FROM AUTHOR]

Objective: To explore the effects of different transplant sites on survivaland androgen section of Leydig cell of adult rat testis. Methods: Healthy adult rats were randomly divided into control group, sham group, subcutaneous group, and kidney capsule group. Rats in control groupkept intact, the remaining rats underwent castration 1 week before testis transplantation. The dorsal skin of rats in control group and sham group were cut. but no testiswastransplanted subcutaneously: 1/3 testis was transplanted subcutaneously at each side of dorsal skin of rats in subcutaneous group, while testis of the same volume was transplanted under the kidney capsule of rats in the kidney capsule group. The grafts were obtained 4 weeks later. Then the Leydig cell were examined by using HE staining and immunohistochemistry staining. And the testosterone concentration of recipient serum was analyzed by ELISA. Results; Interstitial tissues intact were not found in grafts in subcutaneous group and kidney capsule group. Butnumerous HSD-17 β1 -positive cells were observed in samples of both groups. And the number of HSD-17βl-positive cell of control group, subcutaneous group, and kidney capsule were(3.81± 1.32). (9.83± 4.05). and(12.67± 2.81) separately. The testosterone concentration of rat serum of control group, sham group, subcutaneous group, and kidney capsule group were(3.Sl± 1.32). (0.28± 0.08). (0.44± 0.13). and (0.90± 0.31)ngmL separately. The testosterone concentration of kidney capsule group was higher than that in sham group (p<0.0J) and subcutaneous group (p<0.05). while the testosterone concentration of serum in subcutaneous group was higher than that in sham group, but the difference between the two groups was not statistically significant (p>OJ)5). Conclusions: Leydig cells in testis grafts could survive under the kidney capsule or back skin of recipients. However, the microenvironment of under kidney capsule might be more suitable for Leydig cell survival and androgen secretion. [ABSTRACT FROM AUTHOR]

Objective To observe the proliferation and apoptosis of triple negative breast cancer(TNBC) cells MDAMB-468 transfected with microRNA125 b(miR-125 b) inhibitor. Methods MDA-MB-468 cells were divided into the miR-125 b inhibitor group, negative control group, and blank control group. MDA-MB-468 cells of the miR-125 b inhibitor group and negative control group were transfected with miR-125 b inhibitors and nonsense sequence, respectively. At 48 h after transfection, miR-125 b in the three groups was detected by real-time fluorescent quantitative PCR to evaluate transfection efficiency. At 24, 48, 72, 96, and 120 h after transfection, MTT was utilized to observe the proliferation(expressed by OD570). The apoptosis rate was detected by flow cytometry. Western blotting was used to determine the protein expression of Caspase-3 and NF-κBp65. Results MTT assay showed that inhibiting miR-125 b expression suppressed the proliferation of MDA-MB-468 cells at 96 and 120 h after transfection, the OD570 of miR-125 b inhibitor group were 0.32 ± 0.01 and 0.37 ± 0.01, which were lower than that of the negative control group(0.58 ± 0.02 and 0.74 ± 0.01) and the blank control group(0.61 ± 0.01 and 0.75 ± 0.02)(both P < 0.05). At 72 h after transfection, the apoptosis rate of the miR-125 b inhibitor group, negative control group, and blank control group were 24.85% ± 2.21%, 1.47% ± 0.78%, and1.32% ± 0.65%, respectively. Significant difference was found between the miR-125 b inhibitor group, negative control group, and blank control group(P < 0.05); no significant difference was found between the negative control group and blank control group(P > 0.05). Western blotting showed that the protein expression of NF-κBp65 were down-regulated(0.48 ± 0.02) and the Caspase-3 was up-regulated(1.02 ± 0.03) in the miR-125 b inhibitor group as compared with that of the negative control group and blank control group(both P < 0.05). Conclusion Inhibiting miR-125 b expression can suppress the proliferation and induce apoptosis of TNBC cells MDA-MB-468 in vitro by down-regulating NF-κBp65 and upregulating Caspase-3 protein expression in the MDA-MB-468 cells.

Objective To investigate the effect of oxaliplatin injection combined with S-1 on levels of carcinoembryonic antigen(CEA), cancer antigen 199(CA199) and tumor associated materials(TAM) and the quality of life of patients with advanced gastric cancer. Methods The clinical data of 70 patients with advanced gastric cancer treated in our hospital from January 2013 to June 2016 were retrospectively analyzed. According to different chemotherapy regimens, the patients were divided into the study group(n = 35, treated with oxaliplatin injection combined with S-1) and the control group(n = 35, treated with S-1). The short-term curative effect in the two groups was evaluated, and levels of serum tumor markers were detected before and after the treatment. The toxicity and quality of life were evaluated. Results The total effective rate of treatment and disease control rate in the study group were significantly higher than those in the control group(45.71% and 88.57% vs 2.86% vs71.43%)(P<0.05). There were no significant differences in levels of serum CEA, CA199 and TAM between the two groups before the treatment(P>0.05). After the treatment, levels of serum CEA, CA199 and CEA were significantly decreased(P < 0.05), and the decrease was significantly greater in the study group than in the control group(P < 0.05). During and after the treatment, nausea and vomiting was more severe in the study group than in the control group(P < 0.05), while the incidence rates of neutropenia, thrombocytopenia, peripheral neuritis and liver or kidney function damage showed no statistically significant difference(P > 0.05). After the treatment, the improvement rate of KPS score in the study group was significantly higher than that in the control group(60% VS 31.42%),and the overall improvement of the quality of life was significantly better than that in the control group(P < 0.05). Conclusion Oxaliplatin injection combined with S-1 can effectively inhibit the growth and metastasis of tumor cells, remit the condition and improve the clinical efficacy with high safety in patients with advanced gastric cancer. It also can improve the quality of life of patients. [ABSTRACT FROM AUTHOR]

Airborne fine particulate matter poses a serious threat to human health, and investigating the impact of green space landscape patterns on PM2.5 concentrations is conducive to reducing the risk of respiratory diseases by adjusting the green space pattern to decrease PM2.5 concentrations. Utilizing land use remote sensing monitoring data and PM2.5 concentration data in Chongqing city from 1980 to 2020 as the foundational dataset, the landscape pattern index method and spatial autocorrelation analysis were employed to study the characteristics of green space landscape patterns and PM2.5 concentration changes. Furthermore, a geographical and temporal weighted regression(GTWR)model was applied to explore the influence of changes in green space landscape pattern indices on PM2.5 concentrations and their spatiotemporal heterogeneity. The results show that PM2.5 concentrations in Chongqing city gradually increase from 1980 to 2010, followed by a gradual decrease from 2010 to the present; simultaneously, the spatial distribution exhibits significant agglomeration characteristics, primarily manifesting as low-low agglomeration in the east and high-high agglomeration in the west. Area index(TA), patch density index(PD), and patch cohesion index(COHESION)of forest, grassland and agricultural land show significant correlations with PM2.5 concentrations; specifically, area index of forest is negatively correlated, while area indexes of arable land and grassland are positively correlated; patch density indexes of forest and grassland are positively correlated, while patch density index of arable land is negatively correlated; patch cohesion indexes of forest, grassland and arable land are all negatively correlated. In the metropolitan area, area index of grassland and patch density index of arable land exhibit a stronger negative impact on PM2.5 concentrations; in the urban clusters of Three Gorges reservoir area in the northeast and Wuling mountain area in the southeast of Chongqing city, aggregation index(AI), patch density index, patch cohesion index of forest, and area index of arable land exert a stronger influence on PM2.5 concentrations.

BACKGROUND: It may be an important approach to avoiding organ transplant rejection by utilizing immature dendritic cells to induce donor-specific immunologic tolerance. OBJECTIVE: To study the effect of sinomenine on the differentiation and maturation of rat bone marrow-derived dendritic cells in vitro. METHODS: Bone marrow-derived dendritic cells were isolated from the rat femur and tibia, and immature dendritic cells were induced by granulocyte-macrophage colony stimulating factor and interleukin-4. On day 7, lipopolysaccharide was added and the cells were cultured to generate mature dendritic cells. Cells were divided into control group and low-, middle- and high-dose sinomenine treatment groups (SNL, SNM, SNH groups). Forty hours later, dendritic cells were harvested, and cell morphology was observed by inverted phase contrast microscope. The expression of CD80 and RT1B was detected by flow cytometry. ELISA was used to detect the expression of interleukin-12. The mixed lymphocyte reaction was used to detect the ability of dendritic cells to stimulate the activation of allogeneic T lymphocytes. RESULTS AND CONCLUSION: (1) Under the inverted microscope, the morphology of mature dendritic cells was observed in the control group; in the SNL group most dendritic cells were visible; in the SNM group, there were partially suspended cells with poor maturation; and in the SNH group, most of the cells were not mature. (2) The expression of CD80 in the control group was significantly lower than that in the SNL, SNM and SNH groups (P < 0.05), and the expression of RT1B was significantly reduced in the SNM and SNH groups than the control group. (3) Compared with the control group, the level of IL-12p70 in the cell supernatant was significantly decreased in the SNM and SNH groups (P < 0.01). (4) The ability of dendritic cells to stimulate T lymphocyte proliferation in the SNM and SNH groups was significantly decreased compared with the control group (P < 0.05). To conclude, sinomenine can inhibit the maturation of dendritic cells. [ABSTRACT FROM AUTHOR]

Objective: To study the effect of oxaliplatin combined with 5-fluorouracil on serum levels of insulin-like growth factor-1（IGF-1） and transforming growth factor-β1（TGF-β1） of patients with esophageal cancer. Methods: 78 patients with esophageal cancer who were treated in our hospital from September 2014 to August 2015 were selected and randomly divided into the observation group and the control group with 39 cases in each group. The patients in the observation group were treated with oxaliplatin and5-fluorouracil, and the patients in the control group were treated with cisplatin combined with 5-fluorouracil. Then the serum levels of IGF-1 and TGF-β1, the clinical efficacy and adverse reactions in the two groups were observed and compared before and after the treatment. Results: After treatment, the total remission rate in the observation group was significantly higher than that of the control group（P<0.05）. After treatment, the serum levels of IGF-1 and TGF-β1in the two groups were significantly lower than before（P<0.05）. The serum levels of IGF-1 and TGF-β1 in the observation group were significantly lower than those of the control group（P<0.05）. There was no significant difference in the incidence of eukopenia, thrombocytopenia, anemia, alopecia, neurosensory disorder and neuromotor disorder between the two groups（P>0.05）. The adverse reactions of nausea, vomiting, stomatitis and diarrhea in the observation group were significantly lower than those of the control group（P<0.05）. Conclusion: Oxaliplatin combined with 5-fluorouracil regimen can reduce the serum levels of TGF-β1 and IGF-1 in patients with esophageal cancer, with obvious clinical efficacy and safety.

Soil water is central to our understanding of water cycle, groundwater recharge and vegetation restoration in the critical zone of the Loess Plateau. To ascertain the spatial variability of soil water for the entire profile in the critical zone of the Loess Plateau, we obtained soil samples from the top of soil profile to bedrock in five typical sites (Yangling, Changwu, Fuxian, Ansai and Shenmu) based on soil core drilling and analyzed soil water vertical distribution, variation character and spatial structure in the entire soil profiles by classic statistics combining with geo-statistics. Results indicated that mean soil water content in the entire profile decreased at south-north direction in the critical zone of the Loess Plateau. Variabilities of soil water in the five sites all were moderate. Soil water variation in each site became weak gradually and difference in soil water content between the sites decreased as soil depth increased from 40 m to 200 m. Geo-statistics analysis demonstrated that semi-variogram of soil water content in the sites could be fitted well by theory model except Yangling site and exponential model could describe spatial variation structure in the most profiles. These results can benefit the understanding of soil water status and distribution regime in ultra-deep soil profile and are valuable for soil water resources estimation and vegetation restoration in the Loess Plateau.
