Objective:To investigate the effectiveness of mindfulness training on the emotional regulation and resilience of college students.Methods:Eighty one college students were recruited and randomly divided into mindfulness training group and control group, of which 74 completed the study (36 in mindfulness training group and 38 in control group). Participants in mindfulness training group received an 8-week mindfulness training, while participants in control group received no intervention. Participants were assessed with the Five Facet Mindfulness Questionnaire (FFMQ, measuring mindfulness level), Profile of Mood State (POMS, measuring emotion) and the Resilience Scale for Chinese Adolescent(RSCA, measuring resilience) before and after intervention (4 and 8 weeks).Results:Before and after the intervention, the interaction effects of total score of five factors mindfulness, scores of observing, actaware, non-judging, total score of resilience, scores of goal planning, help-seeking and the fatigue score were significant(all P<0.05). There were significant differences in mindfulness level, mood state and resilience scores in mindfulness training group before and after intervention(all P<0.05). There were significant differences of scores of FFMQ , POMS and RSCA post-training compared with baseline( P<0.05). The total score of FFMQ was improved significantly after 4 weeks of intervention ((114.92±11.70) vs(110.36±11.24), P<0.05), while the scores of observing((26.19±5.21) vs(24.00±5.34)), describing((23.36±4.82) vs(21.19±4.76)), non-judging((23.75±4.20) vs(22.06±4.99)) and non-reacting((19.72±3.16) vs(18.58±3.61)) were improved significantly after 8 weeks of intervention. There were significant differences of the scores of fatigue, depression-dejection, panic, vigor-activity and total mood disturbance before and after the intervention in mindfulness training group (all P<0.05). The scores of fatigue((12.31±4.08) vs(13.39±5.12)), panic((12.08±3.57) vs(13.67±4.35)) and total mood disturbance((132.94±17.71) vs(145.75±22.68)) were reduced significantly after 8 weeks of intervention (all P<0.05), while the scores of vigor-activity were improved significantly after 8 weeks of intervention ((18.31±4.61) vs (15.39±4.99), P<0.01). The participants in mindfulness training group got significantly higher total score, scores of goal planning, help-seeking, and affect control of RSCA after intervention compared with baseline (all P<0.05). Conclusion:Mindfulness training can enhance the mindfulness level and resilience of college students, decrease negative affect such as fatigue, depression, panic, and increase positive affect such as activity.

Objective:To explore the impacts on birth situation associated with birth policy adaption in monitoring area of birth defect population in Zhejiang province.Methods:Data were obtained from hospital-based birth defect surveillance system in Zhejiang Province. The surveillance population was childbearing women living in Nanhu of Jiaxing and Fenghua of Ningbo no less than 1 year. We divided data into three groups as "only child" (Jan, 2012-Sep, 2013), "privileged second child" (Jan, 2015-Sep, 2016) and "universal second child" (Jan, 2017-Sep, 2018) according to birth policy adaption. The differences of maternal age distribution in different birth policy periods were compared by using Kruskal-Wallis test. The changing trend of the proportion of parturient in different birth policy periods was analyzed by using Trend χ 2 test. Unconditional logistic regression model was used to analyze the relationship between birth policy and adverse perinatal outcomes. Results:During "only child" , " privileged second child" and "universal second child" period, the number of childbearing women was 12 557, 14 097 and 15 509, respectively, with an increase of 12.3% and 10.0% over previous periods. Maternal ages [ M ( P25, P75)] were [27 (25, 30)], [28 (26, 31)] and [28 (26, 32)] years old. The proportion of multipara in each period was 19.5%, 35.7% and 45.8%, showing an increased trend ( P<0.001). The incidence of adverse perinatal outcomes was lowest in the "only child" period (8.7%) and highest in the "universal second child" period (11.1%). Unconditional logistic regression model showed that after adjusting for age, compared with the "only child" period, the risk of premature birth [ OR values (95% CI) were 1.20(1.08-1.33) and 1.08 (1.02-1.13), respectively] and birth defects [ OR values (95% CI) were 1.33(1.13-1.55) and 1.29 (1.20-1.39), respectively] increased in "privileged second child" and "universal second child" period. The risk of macro infants decreased significantly [ OR values(95% CI) were 0.87 (0.80-0.96) and 0.91 (0.87-0.95), respectively], and the risk of perinatal death changed insignificantly [ OR values (95% CI) were 0.78 (0.53-1.15) and 0.84 (0.69-1.02), respectively]. Conclusion:According to population based surveillance in two regions in Zhejiang, the proportion of women with advanced age, the proportion of multipara , the risks of birth defects increased with birth policy adaption.

Objective This study aims to investigate the sex difference in the hippocampus and parahippocampus in patients with bipolar disorder. Methods We acquired T1－weighted structural MRI from 133 bipolar type I patients (60 males) and 144 normal controls (81 males). The General Linear Model was used to examine the relationship between sex and brain volumes of the hippocampus and parahippocampus, with age and intracranial volume as covariates. Results Patients showed significantly smaller volumes of the bilateral hippocampus and parahippocampus (P＜0.01). There were sex－by－diagnosis interactions in the left parahippocampus gyrus (F=6.534, P=0.044). Male patients had significant smaller volumes of the left parahippocampus gyrus compared to the male normal controls (P＜0.001) whereas the volumes were not significantly different between female patients and female normal controls (P＞0.05). Conclusion The results suggest sex difference in the left parahippocampus gyrus volume in patients with bipolar type I disorder, which deserves further investigation in the future bipolar imaging researches.

OBJECTIVE: To identify the main active components in Ⅲ and their targets and explore the mechanism by which Ⅲ alleviates proteinuria in chronic kidney disease (CKD) based on network pharmacology. METHODS: The active components of Ⅲ and their potential targets, along with the oral bioavailability and drug-like properties of each component were searched in the TCMSP database. The proteinuria-related targets were searched in the GeneCards database. The active component-target network was constructed using Cytoscape software, and the acquired information of the targets from ClueGO was used for enrichment analysis of the gene pathways. RESULTS: A total of 102 active components were identified from Ⅲ. These active components acted on 126 targets, among which 69 were related to proteinuria. Enrichment analysis revealed fluid shear stress- and atherosclerosisrelated pathways as the highly significant pathways in proteinuria associated with CKD. CONCLUSIONS We preliminarily validated the prescription of Ⅲ and obtained scientific evidence that supported its use for treatment of proteinuria in CKD. The findings in this study provide a theoretical basis for further study of the mechanism of Ⅲ in the treatment of proteinuria in CKD.

BACKGROUND/AIMS: Early adverse life events (EALs) are relevant to irritable bowel syndrome in adulthood. Maternal separation (MS), as one of the EALs, has proved to induce visceral hypersensitivity in adult rats. However, the effect of MS on visceral hypersensitvity from the post-weaning period to adulthood remains unknown. METHODS: One hundred and ten neonatal Sprague-Dawley rats were randomly divided into 2 groups: rats in the MS group were exposed to 3 hours daily MS on postnatal day (PND) 2–14; the normal control (NC) group remained undisturbed. Visceral sensitivity was determined by measuring the visceromotor response to colorectal distention on PND21, 35, and 56. Anxiety-like behaviors were measured by the open field test. RESULTS: Compared with NC rats, MS rats showed significant visceral hypersensitivity from the post-weaning period to adult. The proportion of visceral hypersensitive rats decreased with age from 87.5% to 70.0% in the female MS group and from 90.0% to 66.7% in the male MS group. The relative VMR ratio of MS and NC on PND21 was higher than PND35 and PND56. MS rats showed decreased ability of movement and exploration to the novel environment in the post-weaning period, obesity in the prepubertal period, and more anxiety-like behaviors in adulthood. CONCLUSIONS: MS can significantly affect visceral sensitivity and behaviors of rats in different age stages, especially in the post-weaning period. Visceral hypersensitivity of MS rats is more pronounced in the post-weaning period and slightly restored in adults. Thus, visceral hypersensitivity in the post-weaning period might play a more meaningful pathophysiologic role in the formation of adult irritable bowel syndrome.

Objective To provide valuable references for ultrasonic diagnosis of pelvic organ prolapsed (POP) by finding an eas ily detecting referential line based on MRI.Methods Data of 107 patients who underwent pelvic MRI were retrospectively analyzed.All the patients were divided into 6 groups according to age:Group 1 (20 29 years old),group 2 (30-39 years old),group 3 (40-49 years old),group 4 (50-59 years old),group 5 (60-69 years old) and group 6 (≥70 years old group).Four reference lines were set basing on the median sagittal view of T2WI:PS-PS line (the line connecting the two endpoint of the pubic symphysis),PIAS line (the line connecting the inferior margin of pubic symphysis and the bottom of sphincter internal anal sphincter),PPC line (the line connecting of the inferior margin of pubic symphysis and the point of the pubococcygeous attached on the rectum) and PM line (the line connecting of the inferior margin of pubic symphysis and the M point [the midpoint of the line from the crosspoint of PPC line and the front wall of the rectum mucosa to the bottom of sphincter internal anal sphincter]).The angles between the horizontal line and PS-PS line,PIAS line,PM line,PPC line (angle 1,angle 2,angle 3,angle 4) were measured,respectively.The differences of the angle among various age-groups were compared.The consistency between the two observes were evaluated.Results PM line was the closest line to the horizontal line.There was no statistical differences of angle 1,angle 2 and angle 3 among the 6 groups (all P＞0.05).The difference of angle 4 among the 6 groups were significant (F=3.42,P=0.01).Intergroup pairwise comparisons showed that significant differences were found between group 1 and group 4,group 5,group 6,between group 2 and group 4,group 5,group 6,between group 3 and group 4,group 5,group 6,respectively (all P＜0.05).And no significant difference was found in the other comparisons.The consistency of the two observers in meaning angle 1,angle 3 and angle 4 were good,but the consistency of angle 2 was poor.Conclusion Of all the referential lines,PM is the closest to the horizontal line and is less influenced by the patient's age.However,the feasibility of using PM lines as the ultrasound referential line is still unclear.

Objective To investigate the effect of mild hypothermia on expression of autophagyrelated proteins LC3 and Beclin-1 in the hippocampus of rats with traumatic brain injury (TBI).Methods Sixty healthy male adult SD rats were divided into sham group, TBI group, hypothermiatreated group (31-33℃) according to the random number, with 20 rats per group.Rat models of TBI were established using the Marmarou's method.After 4 h of normothermia or hypothermia, the rats were killed 6, 12, 24, and 48 h later.Co-localization of LC3 with neuron specific protein (NeuN) or mammalian target of rapamycinm (mTOR) was determined by double immunofluorescence.Levels of LC3, Beclin-1 and p-mTOR proteins were detected by Western blot analysis.Results LC3 co-localization with NeuN (or mTOR) was observed under confocal laser scanning microscope.In TBI group LC3 and Beclin-1 levels were seen to rise at 6 h, peaked at 24 h and fell slightly at 48 h, but the levels were still higher than these in sham group (P ＜ 0.05).In TBI group p-mTOR level began to decrease at 6 h, reached the lowest point at 12 h, and then ascended at 24 and 48 h, but the level was still lower than that in sham group (P ＜0.05).Mild hypothermia contributed to remarkable decreases in LC3 and Beclin-I expressions, while up-regulating p-mTOR after injury (P ＜ 0.05).Conclusion Mild hypothermia appears to be neuroprotective as it inhibits autophagy in hippocampal neurons after TBI in rats through activation of mTOR signaling pathway.

Objective:To investigate the effect of estrogen on the expression of P2X7 receptor ( P2X7R) in the cerebral cortex and neuroinflammation after subarachnoid hemorrhage ( SAH) in rats.Methods:The rat model of SAH was induced by modified mono-filament puncture method.Sixty male SD rats were divided randomly into three groups:sham group;SAH group and estrogen-treatment group.The local cerebral blood flow was detected with laser doppler blood flow meter.The content of tumor necrosis factor alpha ( TNF-α) and interleukin-6 (IL-6) were measured by ELISA analysis.The expression of P2X7R in the cerebral cortex was tested by immuno-histochemical and Western blot methods.Results:Compared with that in Sham group,cerebral blood flow was significantly decreased after SAH (P<0.05),the content of TNF-αand IL-6 in the cerebral cortex were significantly up-regulated at each time point after SAH (P<0.05),peaked at 24 h,and the expression of P2X7R significantly increased at 6 h,12 h and 24 h after SAH (P<0.05),peaked at 12 h.Compared with that in SAH group,cerebral blood flow was significantly increased in estrogen-treatment group (P<0.05),the levels of TNF-α,IL-6 and P2X7R were down-regulated in estrogen-treatment group ( P<0.05).Conclusion: Estrogen could attenuate neuroinflammation in the cerebral cortex after subarachnoid hemorrhage in rats, which may be associated with the down-regulation in P2X7R proteins.

Objective To explore the application and effects of bone lengthening growth diary in self management of patients after lower limb lengthening. Methods A total of 54 cases applying lower limb lengthening were divided into the experimental group (n=28) and the control group (n=26) with random digit table.
