Objective:To analyze the current situation and effect of mobile applications for physical activity management in China.Methods:In this systematic review, search terms such as “exercise”, “sports”, “exercise”, “physical activity” and “mobile health” were used to retrieve the applications for physical activity management in the IOS Application Store developed in mainland of China. Then the Mobile Application Rating Scale (MARS) and the Behavior Change Technology (BCT) were used to evaluate the quality of the applications and analyze the behavior change technologies that applications adopted. Moreover, a systematic review of relevant experimental studies was applied to summarize the effectiveness of the applications in promoting physical activity.Results:Total of 141 applications were included in this analysis, and 58 behavior change techniques in 16 categories were applied. The most frequently used 4 categories of BCT were behavior comparison (67.4%), repetition and substitution (67.4%), knowledge construction (67.4%), feedback and monitoring (58.2%). The overall objective quality score of MARS was 3.17±0.42, of which, the score of engagements, functionality, aesthetic design and information quality was 2.67±0.73, 3.75±0.54, 3.44±0.59 and 2.83±0.55, respectively. The number of BCT adopted in each application had a linear relationship with the application′s objective quality score in MARS ( B=0.023, 95% CI: 0.018-0.029) and user rating ( B=0.040, 95% CI: 0.019-0.060) (both P<0.001). A total of 4 articles were included to test the effects of techniques (i.e., physical activity behavior monitoring, physical activity planning and physical activity guidance) in 4 applications. The overall quality of the literatures was good. The main outcomes were physical activity duration (3 articles) and step count (1 article). Compared with those who did not use the application or only used the accelerometer to monitor physical activity, subjects who used the application to monitor physical activity had significant longer physical activity durations and step count (both P<0.05). Conclusions:The number, function and technology of physical activity management applications in China are abundant, but the quality of the applications is moderate. The number of BCT is an important factor in evaluating application′s quality, but its effect on behavior change is still not clear.

Objective: To quantitatively detect CD44 expression in patients with nonalcoholic fatty liver disease (NAFLD) for comparative analysis. Methods: Patients with chronic liver diseases accompanied with or without NAFLD, including chronic hepatitis B, cirrhosis and hepatocellular carcinoma after chronic hepatitis B, and healthy blood donors as normal controls who admitted to the Affiliated Hospital of Nantong University from May to October 2018 were selected. The proportion of CD44 positive cells was analyzed by flow cytometry. CD44 level was quantified by an enzyme-linked immunosorbent assay, and the biochemical indicators such as serum aspartate aminotransferase, alanine aminotransferase activity, total cholesterol and triglyceride were routinely analyzed. The cancerous and adjacent cancerous tissues of patients accompanied with or without NAFLD were collected by self-matching method and analyzed by immunoblotting and histochemistry and compared by CD44 integrated optical density. Image-Pro Plus version 6.0, Image J, GraphPad Prism 5.0, Photoshop, Microsoft Excel and IBM SPSS statistics 23 were used to analyze and draw pictures. An independent sample t-test was used to compare the differences between groups. Results: Patients accompanied with NAFLD had hepatocyte injury and dyslipidemia. NAFLD and chronic liver disease patients had significantly elevated serum CD44 levels than normal control group (P < 0.01). CD44 positive lymphocyte ratio was 78.19 % ± 16.33 % in NAFLD patients and 68.47% ± 20.91% in chronic hepatitis B group, which was higher than the control group (46.51% ± 20.52%). Chronic hepatitis B group with steatosis had significantly higher CD44 concentration (181.42 ± 49.36) ng/ml than chronic hepatitis B group (142.52 ± 53.87) ng/ml and normal control group (99.47 ± 15.23) ng/ml. CD44/GAPDH ratio in the liver cancer group (1.306 ± 0.614) was significantly higher than paracancerous group (0.477 ± 0.291) and the difference between the two groups was statistically significant (t = 3.451, P = 0.004). The integrated optical density of CD44 in the NAFLD-related liver cancer and paracancerous group were 25.721 ± 5.881 and 14.155 ± 4.001 and the difference between the groups was statistically significant (t = 14.544, P < 0.001). The pathological features of high expression of CD44 in patients with hepatocellular carcinoma were significantly correlated with HBV infection, tumor size, single/multi-center, and lymph node metastasis, degree of differentiation, TNM grade, Child-Pugh score, portal vein tumor thrombus and extrahepatic metastasis. HCC patients with NAFLD had significantly higher serum CD44 (234.62 ± 69.40) ng/ml than patients without NAFLD (186.49 ± 58.89) ng/ml (t = -3.191, P = 0.002), but there was no statistically significant difference in the clinicopathological characteristics between the high/low CD44 groups of HCC patients with NAFLD. Conclusion The results suggest that CD44 is abnormally activated and its mechanism may play an important role in the progression of NAFLD.

OBJECTIVETo determine the compound Daqiqi decoction( CDQD) combined cisplatin plays on the cell apoptosis of subcutaneous transplanted ovarian cancer in nude mice, to provide theory evidence for clinical treatment.

METHODMaking the models of subcutaneous transplanted ovarian cancer in nude mice, and divide the 40 mice with tumor into 5 groups (n = 8), the model control group, CDQD low dosed group, CDQD high dosed group, cisplatin group, cisplatin combined CDQD group, killing all the mice after 3 weeks' treatment and stripping tumors. Measure the volume and weight of the tumor and calculate tumor growth curve damps, the inhibition rate. Examining the expression of the Bcl-2(B-cell leukemia /lymphoma 2) and Bax (Bcl-2 associated x protein) mRNA and protein by the RT-PCR and the Western blot.

RESULT(O)The tumor weight shows that there was certain lighter effect in each CDQD group, and compared with cisplatin groups has no statistical significance, the cisplatin combined CDQD group is obviously lighter than that of the other group(P <0.01). The tumor growth curve damps shows that compared with model control group, the treatment group tumors had some extent narrowing (P < 0.01). (2) RT-PCR results: Bax (Bcl-2 associated x protein) mRNA expression shows that compared with model control group, the treatment group has increased (P < 0.01), and the cisplatin combined CDQD group compared with the other group is the highest, there was significant difference with the rest of the treatment group (P < 0.01). In the Bcl-2 mRNA express lowest in cisplatin combined CDQD group (P < 0.01), there has no difference between CDQD high dose group and cisplatin group. (Western blot shows: compared with model control group, the Bax protein of treatment group has increased expression (P < 0.01), the expression of Bax protein in cisplatin combined CDQD group is the highest(P < 0.01). There has no difference between CDQD high dose group and cisplatin group. The Bcl-2 protein expression of the cisplatin combined CDQD group is the lowest (P < 0.01), there has no difference between CDQD high dose group and cisplatin group.

CONCLUSIONThe effect of CDQD on subcutaneous transplantation ovarian tumor has promoting apoptosis function, its mechanism may be related to downgrade the Bcl-2 expression, higher expression of bax, stimulation on the apoptosis of tumor cells; cisplatin combined CDQD have synergistic effect.

OBJECTIVETo summarize the experience with emergency coronary artery bypass grafting (ECABG) for management of acute coronary syndrome and analyze the mid-term follow-up results.

METHODSForty-five ECABG surgeries were performed in 34 male and 11 female patients (aged 65.6∓5.8 years) for cardiogenic shock (5 cases), acute heart failure (6 cases) and refractory unstable angina (34 cases). Twenty patients received the operation within one week after acute myocardial infarction (AMI) and 18 were preoperatively supported by intra-aortic balloon pumping (IABP). All patients had triple-vessel disease and 15 had left main stenosis. Ten patients experienced two myocardial infarctions and 6 had chronic renal dysfunction including two requiring hemodialysis. On-pump operations were performed in all cases with a mean CPB time of 104.2∓29.7 min and cross clamping time of 69.0∓21.3 min. Cold blood or HTK cardioplegia was used for myocardial protection. The left internal mammary artery (LIMA) was routinely anastomosed to the left anterior descending artery (LAD), and the great saphenous vein (GSV) to other target vessels. The mean number of grafts was 2.9∓0.6.

RESULTSForty-one patients were cured and discharged and 4 patients died with an in-hospital mortality of 8.9%, including one associated with cardiac event (2.2%). IABP was weaned off within 28.5∓10.6 h after surgery except for one patient who died of multiple organ and system failure (MOSF). Thirty-eight patients (92.7%) were followed up for a mean of 37.3∓16.7 months, during which 2 patients died with a mid-term survival rate of 94.7%. Thirty-five (92.1%) patients had New York Heart Association (NYHA) class I and II. The freedom from cardiac event was 90.5%. Follow-up echocardiography showed significantly improved left ventricular dimension and ejection fraction in these cases (P<0.05), and graft patency was 95.8% for the LIMA and 90.5% for the GSV.

CONCLUSIONDespite a slight increase of the in-hospital mortality, ECABG can improve the mid-term survival, freedom from cardiac event, and cardiac function when the indications and timing for surgery are well controlled with optimal perioperative management.

A series of phthalazine ketone compounds were synthesized and the structures were confirmed by H NMR and HR-MS spectrum. All target compounds were obtained through 7 steps, including selective reduction, nitration, bromination, ring enlargement, reduction, Knoevenagel and acylated reaction. The compounds were evaluated for their immunosuppressive effects of T-cell proliferation and inhibitory activity of IMPDH type II in vitro, as well as their structure-activity relationship were assessed. Several compounds exhibited strong immunosuppressive properties, especially compounds 7f and 7h, with IC50 values of 0.093 micromol x L(-1) and 0.14 micromol x L(-1) respectively, which were superior to mycophenolic acid. The information obtained from the studies may be useful for further research on the immunosuppressive agents.
