Objective To provide data for reference on the impact of cyclosporin A (CsA) on the proliferation of the bone marrow mesenchymal stem cells in MDS patients through the investigation of the impact of cyclosporin A on human bone marrow mesenchymal stem cell proliferation. Methods The absorption rates of the bone marrow mesenchymal stem cells in the control group and the MDS patient group were determined by using the tetrazolinm salt (MTT) micro-colorimetric enzyme reaction. The concentrations of cyclosporine A are 2.5×10~4 ng/μl, 2.5×10~3 ng/μl, 2.5×10~2 ng/μl and 2.5×10ng/μl respectively. Results There is no significant difference between the each result by using different concentrations of CsA., which indicates the impact of CsA on the growth of mesenchymal stem cells is not significant(P >0.05). In the serial of concentrations mentioned, no cytotoxicity of CsA is observed. However, there is difference between the selected indicators of the control group and the patient group (P <0.01), and the value of the MDS patient group is higher than that of the control group. There is no statistic difference between the concentration of CsA and the data obtained from interactions between different groups (P >0.05). There is no significant difference between the absorption rates of the group treated by CsA of every concentration and the corresponding control group. Conclusion The impact of CsA on the bone marrow mesenchymal stem cell proliferation is significant in neither healthy people nor MDS patients.

Objective:To evaluate the effect of mechanical chest compression device in patients with cardiac arrest.Methods:The relevant literatures about mechanical cardiopulmonary resuscitation and manual cardiopulmonary resuscitation were systematically searched from China Knowledge Network (CNKI), VIP, Wanfang, PubMed, Web of Science and other databases. The effective data were extracted and analyzed by RevMan5.3 software.Results:A total of 20 clinical studies involving 29 727 patients were included, of which 11 104 patients received mechanical cardiopulmonary resuscitation and 18 623 patients received traditional manual cardiopulmonary resuscitation. The results of meta-analysis showed that mechanical cardiopulmonary resuscitation could not effectively improve the restoration of spontaneous circulation (ROSC) rate, admission survival rate, discharge survival rate and neurological prognosis in patients with cardiac arrest compared with manual cardiopulmonary resuscitation. ROSC occurrence rate ( RR=1.10, 95% CI: 0.99-1.23, P<0.01), admission survival rate ( RR=1.01, 95% CI: 0.95-1.08, P=0.67), discharge survival rate ( RR=1.00, 95% CI: 0.86-1.15, P=0.14), and good neurological function rate ( RR=0.81, 95% CI: 0.61-1.06, P=0.69) showed no significant differences between the mechanical cardiopulmonary resuscitation and manual cardiopulmonary resuscitation. Conclusions:Mechanical chest compression device has no advantage compared with manual cardiopulmonary resuscitation. Mechanical cardiopulmonary resuscitation is not recommended to completely replace manual chest compression in cardiopulmonary resuscitation.

Objective:To investigate the effects of 3-methyladenine(3-MA)on extracellular matrix deposition in early diabetic nephropathy(DN)and its mechanism.Methods:A streptozotocin(STZ)-induced type 1 diabetes mouse model was used, and the mice were divided into vehicle control group, diabetes group(STZ group), 3-MA group, and chloroquine(CQ)group, 8 mice in each group. After 6 weeks of intervention, both kidneys were harvested, and the kidney-to-body weight ratio was recorded. Western blotting was performed to detect protein expressions of renal cortex fibronectin, α-smooth muscle actin(α-SMA), LC3, Beclin 1, p62, and vascular endothelial growth factor(VEGF). Immunohistochemistry was used to observe kidney fibronectin staining. Bioinformatics analysis was conducted on shared genes between diabetic nephropathy(DN)gene targets and 3-MA predicted gene targets.Results:Both 3-MA and CQ exhibited certain hypoglycemic effects in diabetic mice. Compared to the STZ group, the kidney-to-body weight ratio decreased in the 3-MA group( P<0.05). Western blotting showed that 3-MA reduced the expression of renal cortex matrix-related proteins fibronectin and α-SMA in diabetic mice( P<0.05 or P<0.01). Immunohistochemistry also revealed that 3-MA reduced fibronectin staining in the kidneys of diabetic mice. Both 3-MA and CQ inhibited the protein expression of renal cortex Beclin 1 in diabetic mice(both P<0.05), while 3-MA increased the expression of renal cortex p62( P<0.05). Bioinformatics analysis indicated a connection between shared genes of DN gene targets and 3-MA predicted gene targets with the VEGF signaling pathway. Western blotting results further showed that 3-MA reduced renal cortex VEGF expression in diabetic mice( P<0.01). Conclusion:3-MA can alleviate extracellular matrix deposition in the kidneys of early DN mice by inhibiting the VEGF signaling pathway.

OBJECTIVETo investigate the associations between physical exercise and quality of life in breast cancer patients.

METHODSA cross-sectional study was conducted among 3 344 community breast cancer patients between April and July 2013 in Shanghai, China. Data were collected using a questionnaire, including socio-demographic situation, cancer survival and health behaviors, and scores of EORTC QLQ-C30 Simplified Chinese version and FACT-G Simplified Chinese version.

RESULTSAmong a total of 3 344 breast cancer patients, the patients doing exercise reported significantly higher EORTC physical functioning scores, role functioning scores, emotional functioning scores, global health scores, and FACT-G physical well-being scores, social well-being scores, emotional well-being scores, functional well-being scores, and FACT-G total scores than the patients who didn't take exercise (P < 0.05, P(Adjusted)<0.05) . Breast cancer patients who did exercise more than or equal to 5 times/week reported significantly higher EORTC role functioning scores, cognitive functioning scores, emotional functioning scores, global health scores and FACT-G physical well-being scores, functional well-being scores, and FACT-G total scores than patients who did exercise less than 5 times/week (P < 0.05, P(Adjusted)<0.05 ).

CONCLUSIONSThere are active associations between physical exercise and quality of life in breast cancer patients. Engagement in physical exercise is beneficial to breast cancer patients with long-term survival.

Objective:To compare the clinical outcomes of treatment using non-selective versus highly selective partial splenic embolization in patients with hypersplenism secondary to liver cirrhosis.Methods:The clinical data of patients with hypersplenism secondary to hepatitis B cirrhosis who underwent splenic embolization at the Department of Hepatobiliary and Pancreatic Surgery of Leshan People's Hospital from July 2017 to July 2020 were analyzed retrospectively. Of 65 patients with hypersplenism, there were 42 males and 23 females, with age of (58.5±9.8) years. Twenty-six patients underwent splenic artery non-selective partial splenic embolization (the non-selective group) and 39 patients underwent partial splenic embolization using highly selective intubation (the highly selective group). The postoperative peripheral hematological indexes, liver function, operation-related complications and portal vein color Doppler ultrasonography were compared between the two groups.Results:The white blood cell count and platelet count of patients in the 2 groups were significantly higher than those before operation. The white blood cell count at 4, 12 and 24 weeks after operation and the platelet count at 12 and 24 weeks after operation in the highly selective group were significantly higher than those in the non-selective group ( P<0.05). Compared with the non-selective group, the total bilirubin, ICG-R15, portal vein diameter and portal vein blood flow in the highly-selective group significantly lower ( P<0.05). The incidences of 0/Ⅰ/Ⅱ/Ⅲ pain in the non-selected group was significantly higher when compared with that in the highly selected group (5/10/11/1 vs. 12/22/7/0), ( P<0.05). There were no significant differences in the incidences of postoperative complication between the two groups ( P>0.05). Conclusion:Compared with non-selective partial splenic embolization, highly selective partial splenic embolization gave more stable and lasting treatment outcomes in patients with hypersplenism caused by liver cirrhosis with better recovery of blood-related indicators, better improvement in postoperative liver function and relief of portal hypertension symptoms.

Objective:To evaluate the outcome of the patients receiving dispatcher-assisted cardiopulmonary resuscitation (DA-CPR) delivered by first-responders who witnessed the out-of-hospital cardiac arrest (OHCA) before the Emergency Medical Service (EMS) arrived.Methods:We performed a search of the relevant literature exploring major scientific databases. We assessed the quality of the included cohort study according to the Cochrane Handbook for Systematic Reviews of Interventions Version 5.1.0. Meta-analysis was performed on three outcome indicators (recovery of spontaneous circulation survival to hospital discharge and survival with favourable neurologic outcome) using the Revman5.3 software.Results:A total of 21 studies with 349 822 patients were selected for the meta-analysis, including 182 125 patients in the DA-CPR group and 167 697 in the CPR-only group. The meta-analysis showed no significant difference between the DA-CPR and CPR-only groups in ROSC [ RR=1.10, 95% confidence interval ( CI): 0.94-1.29, P=0.24], survival to hospital discharge ( RR=1.10, 95% CI: 0.90-1.34, P=0.34) and survival with favourable neurologic outcome ( RR=1.01, 95% CI: 0.79-1.28, P=0.97) of the patients in America, Japan and Korea. However, there was a significant difference between the DA-CPR and the CPR-only groups in ROSC ( RR=2.61, 95% CI:1.53-4.46, P=0.0005), survival to hospital discharge( RR=6.08, 95% CI: 1.84-20.04, P=0.003), and survival with favourable neurologic outcome( RR=9.76, 95% CI: 1.87-51.02, P=0.007) of the patients in China. Conclusions:The overall effect of DA-CPR is significantly different for each country. In detail, DA-CPR offers a survival advantage (Return of spontaneous circulation, survival to hospital discharge and survival with favourable neurologic outcome) over CPR alone in China but no advantage in developed countries.
