Objective To explore the effect of pacifiers plus touching intervention on venipuncture-induced pains in newborn babies.Methods Ninety two neonates undergoing venous puncturing were randomly divided into touching intervention group and pacifiers plus touching group.During and after the venipuncture,the neonatal pain score,heart rate and blood oxygen saturation were compared between the two groups.Results The degree of pain perception in the pacifiers plus touching group was significantly lower than that in the only touching group(P<0.001).During and afterpuncturing the heart rate of the pacifiers plus touching group was significantly lower than that in the only touching group.However,the blood oxygen saturation was significantly higher(P<0.05). Conclusion Pacifiers plus touching can effectively relieve venipuncture-induced pains in neonates.

Objective To explore the clinical characteristics in patients with histiocytic necrotizing lymphadenitis (also called Kikuchi-Fujimoto' s disease,KD) and meningitis.Methods We reported a patient who developed meningitis preceding the other presentations of KD with abnormal serum autoimmune phenomena,and systematically reviewed 19 cases of KD with meningitis that had been reported worldwide,and analyzed the clinical parameters and treatments.Results The present case was a 25-year-old female subject with serum antinuclear factor antibody and anti-ribonucleoprotein antibody positive.The patient recovered after treatment with steroid and no recurrence was appeared.Among the 19 patients,the average age was 20.2 years,sex ratio was 10:9 (10 female:9 male),7 patients had abnormal serum autoimmune phenomena,7 patients'initial symptom was meningitis and 5 patients were administrated with steroid.Conclusions The onset age in KD with meningitis is earlier than the common KD,and sex ratio in KD with meningitis is close to 1∶ 1.A definitive diagnosis of the disease is determined by a lymph node biopsy at present.

Objective:To establish a suitable quality evaluation index system of open online courses in military continuing education.Methods:A primary index system program was established through literature review and small expert meeting. Delphi method was used to conduct a letter consultation among 50 experts, and the index system was revised according to the experts' advice and they consulted again until a broad agreement was reached.Results:After two rounds of letter consultation, the recognition rate of 43 experts on the naming and connotation of the indexes reached more than 95%, and their opinions basically reached a consensus. The variation coefficients of the index weights were distributed between 0.00 and 0.10, with a high degree of concentration. A quality evaluation index system of open online courses in military continuing education has been established, including 4 first-level indexes: curriculum design, curriculum production, online operation and curriculum effect, 10 second-level indexes, and 25 third-level indexes.Conclusion:The quality evaluation index system could provide a basis for evaluating online course quality scientifically and offer better educational resources and teaching services.

OBJECTIVETo investigate the function of repair gene LIG4 in radiosensitivity enhancement of rectal cancer cells by curcumin.

METHODSHuman rectal cancer cells HT-29 were cultured in normal. LIG4-overexpression HT-29 cells and blank control plasmid HT-29 cells were established by gene transfection. Both kind of HF-29 cells were further randomly divided into curcumin group, radiotherapy group, curcumin plus radiotherapy group (combined group) and control group. The growth inhibition and apoptosis of cells were detected by MTT and Annexin V/PI respectively. Change of tumor volume was observed in nude mouse xenograft model, and the apoptosis of tumor cells was analyzed by TUNEL.

RESULTSRegarding blank control plasmid HT-29 cells, the growth inhibition rate and apoptosis rate in combined group were significantly higher than those in radiotherapy group(all P<0.05); tumor volume of nude mouse in combined group was significantly smaller than that in radiotherapy group, and the apoptotic index in combined group was significantly higher than that in radiotherapy group (all P<0.05). However, regarding LIG4-overexpression HT-29 cells, the growth inhibition rate and apoptosis rate were not significantly different between combined group and radiotherapy group(all P>0.05); the tumor volume of nude mouse and the apoptotic index were also not significantly different between combined group and radiotherapy group (all P>0.05).

CONCLUSIONDown-regulation of LIG4 is an important mechanism of radiosensitivity enhancement of rectal cancer cells by curcumin.

Objective: To investigate the clinicopathological features of mammary analogue secretory carcinoma (MASC) of salivary glands, and its diagnosis, differential diagnosis, immunohistochemistry and molecular pathology. Methods: Seventeen cases of MASC were enrolled, with 9 cases of salivary acinar cell carcinoma and 18 cases of adenoid cystic carcinoma as control groups from Nanjing General Hospital from 1997 to 2014 were included in this retrospective study, combined with immunohistochemistry and molecular detection of ETV6-NTRK3 gene fusion. All cases were histologically reviewed with immunohistochemical staining (EnVision) for S-100 protein, SOX10, GATA3, CD117 expression in each group. Fluorescence in situ hybridization (FISH) was used to detect the ETV6-NTRK3 gene fusion. Results: The age of MASC patients ranged from 27 to 74 years with mean age of 47 and ratio of male and female was 4∶3. All cases showed infiltrative growth and diverse cytology and histology, including lobular (8 cases), cystic papillary (3 cases), cribriform mixed with papillary and glandular structures (6 cases) at various proportions. Some tumors of MASC also exhibited solid growth areas with occasional microcystic honeycombed pattern composed of small cysts merged into larger cysts resembling thyroid follicles. S-100 protein and SOX10 were strongly positive in all MASC cases (17/17). In addition, there was insignificant positivity for GATA3 (3/17) and CD117 (4/17). ETV6 gene fusion detection was informative in 12 MASC cases by FISH with 10 positive cases and 2 negative cases. Conclusions Combined immunohistochemical positivity of S-100 protein, CD117 and SOX10 are useful in the diagnosis and differential diagnosis of MASC. FISH detection of ETV6-NTRK3 fusion offers an additional molecular diagnostic marker for the diagnosis.

Objective:To explore the relationship between proactive personality, resilience and achievement motivation of military cadets, and to explore the mediating role of resilience between proactive personality and achievement motivation, as well as the moderating effect of cadets’leading ability on this mediating role.Methods:In this study, 109 military cadets were measured with proactive personality scale, Connor-Davidson resilience scale (CD-RISC) and achievement motivation scale. SPSS 26.0 was used for descriptive statistical analysis and correlation analysis.Results:①There was a significant correlation among the total scores of proactive personality, resilience and achievement motivation ( Ps<0.01). ②Proactive personality could significantly predict the level of achievement motivation ( a=0.454, P<0.001), and resilience could significantly predict the level of achievement motivation ( b=0.231, P=0.019). ③Resilience significantly mediated the relationship between proactive personality and achievement motivation ( c′=0.3, P=0.003). ④Cadets' leading ability moderated the effect of resilience on achievement motivation (index=0.338, 95% CI: 0.057 to 0.881). The mediating effect of resilience between proactive personality and achievement motivation was significant for cadets' leaders (Effect=0.381, 95% CI: 0.085 to 1.005), but not significant for other students (Effect=0.043, 95% CI: -0.069 to 0.252). Conclusion:The proactive personality of military cadets can affect the level of achievement motivation through psychological resilience, which is also moderated by cadre identity, suggesting that military education should improve the level of achievement motivation in many ways.

Objective:To investigate the relationship between resilience, perceived social support, and adaptability in military freshmen.Methods:A total of 195 freshmen were randomly selected from a military medical university. The Chinese version of Connor-Davidson Resilience Scale (CD-RISC), the Perceived Social Support Scale (PSSS), and a self-test questionnaire of college students' psychological adaptability were used to investigate their resilience, perceived social support, and adaptability. SPSS 26.0 was used to perform an independent samples t-test and a Pearson correlation analysis to analyze the differences in these scores between freshmen with different demographic characteristics and the correlation between these scores. By using the PROCESS plug-in, a structural equation model was used to analyze the mediating effect of resilience on the relationship between social support and psychological adaptation, which was further tested using the Bootstrap method. Results:The independent samples t-test showed that females had a significantly higher score of other support than males ( t = -2.05, P = 0.041), and student leaders had significantly higher scores of family support and other support, total score of social support, and score in psychological adaptability than other students (all P<0.05). The correlation analysis showed that there were significant positive correlations between the scores of PSSS and its each item, CD-RISC, and self-test of college students' psychological adaptability (all P<0.05). The structural equation model showed that resilience partially mediated the relationship between social support and psychological adaptation, and the Bootstrap method revealed a significant indirect effect (95%CI: 0.102-0.253). Conclusion:Resilience plays a partial mediating role between perceived social support and adaptability in military freshmen. They should be guided to correctly perceive external support and develop strong resilience.

Objective:To investigate the expression of hippocampal synapse-related proteins including synaptophysin (SYN), postsynaptic density protein 95 (PSD95) and growth-associated protein 43 (GAP43) in rats with epilepsy accompanied by depression.Methods:The 3-month-old female clean grade SD rats were selected for the experiment.Lithium chloride pilocarpine was used to establish an epileptic rat model. Rats with successful epilepsy models were divided into epileptic depressive group (EWD group)and epileptic group with 10 in each group based on whether they were accompanied by depression. Furthermore, ten rats with matched body mass were taken as the depressive group and 10 were taken as control group. As for the depressive group rats, chronic unpredictable mild stress stimulation combined with orphanage was adopted to establish a model of depression.The depressive behaviors of rats were evaluated by body mass, sucrose preference test and open field test. Immunohistochemical staining and Western blot were used to detect the expression of SYN, PSD95 and GAP43 proteins in rat hippocampal tissue. SPSS 17.0 software was used for data statistical analysis, repeated measurement ANOVA was used for behavioral results, one-way ANOVA was used for inter group comparison of protein expression data, and LSD test was used for further pairwise comparison.Results:As for the body mass, there was significant interaction effect between the time and group among the 4 groups ( F=7.33, P<0.01). On the 8th day and the 29th day, the body weight of rats in the EWD group and the depressive group were lower than those in the epilepsy group (all P<0.05). The body weight of rats in the EWD group on the 29th day was lower than that on the first day ( P<0.05). As for the sucrose preference rates, there was significant interaction effect between the time and group among the 4 groups( F=2.67, P<0.05). The sucrose preference rate of EWD group on the15th and 29th day were lower than that on the first day (both P<0.05). The results of the open field test showed that the interaction effects of the number of vertical standing times( F=2.74) and the number of horizontal movement lattices ( F=1.76) both were not significant (both P>0.05), but both the time effect and group effect were significant (vertical standing times: Ftime=4.35, P<0.05, Fgroup=25.64, P<0.01; horizontal movement lattices: Ftime=12.75, P<0.01, Fgroup=21.37, P<0.01). The immunohistochemical results showed that there was a statistically significant difference in the number of positive cells expressing synaptic proteins SYN, PSD95 and GAP43 among the four groups of rats ( F=93.85, 58.66, 98.84, all P<0.05). The numbers of positive cells of SYN (11.73±4.30), PSD95 (24.47±7.58) and GAP43 (9.40±3.50) in the epilepsy group were lower than those in the control group ((51.00±15.39), (55.60±13.17) and (29.53±4.05)) (all P<0.05). The numbers of positive cells of SYN (5.80±3.53), PSD95 (12.87±4.03) and GAP43 (5.33±3.50) in the EWD group were lower than those in the depressive group ((11.33±3.22), (48.13±12.69) and (15.47±5.21) )(all P<0.05). Western blot results showed that there were statistically significant differences in the expression of synaptic proteins SYN, PSD95 and GAP43 among the four groups of rats ( F=13.19, 9.38, 16.80, all P<0.05). The expression levels of SYN, PSD95 and GAP43 in the epilepsy group were lower than those in the control group (all P<0.05). The expression levels of SYN, PSD95 and GAP43 in the EWD group were lower than those in the epilepsy group and the depressive group (all P<0.05). Conclusion:The low expression of SYN, PSD95 and GAP43 proteins in the hippocampus of rats with epilepsy accompanied by depression may be related to their pathogenesis.

Coronary heart disease (CHD) is a kind of cardiovascular diseases originated from atherosclerosis (AS), and chronic inflammation is one of the pathological characteristics. The peripheral blood leukocytes, especially mononuclear cells, play an important role in the AS processes. Recently, in a series of Epigenome-Wide Association Studies (EWAS), multiple DNA differential methylation sites in peripheral blood cells were found to be statistically associated with CHD, which suggested that these DNA differential methylation sites might serve as new risk factors for CHD. The recognition of the variant of DNA methylation as a common epigenetic nucleic acid modification in the occurrence and development of CHD, is ongoing. DNA methylation has the potential to become warning biomarkers, which might provide new ideas and evidences for mechanistic studies of CHD.
