Objective:To explore the intervention effect of motivational interviews based on timing theory on self-efficacy, negative affect and coping styles of parents with infantile spasms children.Methods:Cluster sampling was used to select 82 parents of infantile spasms hospitalized in the Department of Neurology of a children’s hospital, a three-A hospital from January 2019 to October 2019. They were divided into control group and observation group with 41 cases each according to random number table. The control group received routine health education, and the observation group received five motivational interviews based on timing theory interventions on the basis of routine care. The effect of the intervention was evaluated by General Self-Efficacy Scale (GSES), Hospital Anxiety and Depression Scale (HADS), and the Chinese version of Coping Health Inventory for Parents (CHIP) before intervention, on the day of discharge, and 3 months after discharge.Results:Before the intervention, there was no significant difference in the scores of GSES, HADS and CHIP scales between the parents of the two groups ( P>0.05). After intervention, The GSES scores of the observation group on the day of discharge and 3 months after discharge were (19.63±0.87) and (22.58±1.28) points, which were significantly higher than (18.92±0.74) and (19.46±1.25) points of the control group. The difference between both groups was statistically significant ( t values were -3.865, -10.926, P<0.01). HADS-A/HADS-D scores of the observation group on the day of discharge and 3 months after discharge were (12.50±0.82), (10.50±0.87) and (9.78±0.80), (8.63±0.87) points, respectively. The HADS-A/HADS-D scores of the control group on the day of discharge and 3 months after discharge were (12.92±0.74), (11.72±0.99) and (10.23±0.78), (9.38±1.04) points, respectively. The difference was statistically significant ( t values were 2.412-5.764, P<0.05 or 0.01). The observation group scores on CHIP subscales on the day of discharge and 3 months after discharge are higher than the control group, the difference was statistically significant (t values were -7.93--2.490, P<0.05 or 0.01). Conclusions:Motivational interviews based on timing theory can enhance parents’ self-efficacy, improve their negative emotions and family coping styles, and thereby promote the recovery of children.

Objective:To investigate the effect and mechanism of NOD-like receptor family pyrin domain containing 12 (NLRP12) knockdown on inflammatory factor levels and retinal injury in retinal ganglion cells (RGCs) of rats with high intraocular pressure.Methods:Seventy SPF adult male SD rats were selected and randomized into control group, high intraocular pressure (IOP) group, high IOP+ small interfering RNA negative control (siNC) group, high IOP+ siNLRP12 group and high IOP+ siNLRP12+ recombinant rat caspase-1 (rrcaspase-1) group, with 14 rats in each group.Rats in the control group were only treated with conjunctival incision in the right eye, and ocular hypertension model was established in the other four groups with external scleral vein cauterization.High IOP+ siNC group, high IOP+ siNLRP12 group and high IOP+ siNLRP12+ rrcaspase-1 group were injected with siNC, siNLRP12 and siNLRP12+ rrcaspase-1 reagent via the tail vein, respectively.The IOP of the right eye was measured at 1 day, 1, 2 and 3 weeks after the operation.Three weeks after the operation, the retinal structure was observed by hematoxylin-eosin staining, and the number of RGCs in each group was counted.RGCs were divided into control group, rrcaspase-1 group, siNC+ rrcaspase-1 group, siNLRP12+ rrcaspase-1 group.The cells in rrcaspase-1 group, siNC+ rrcaspase-1 group and siNLRP12+ rrcaspase-1 group were treated with rrcaspase-1, siNC+ rrcaspase-1 and siNLRP12+ rrcaspase-1 reagent for 24 hours, respectively.No treatment was given to the control group.The expression levels of NLRP12, caspase-1 and cleaved-caspase-1 proteins in RGCs and retinal tissue were detected by Western blot.The concentrations of tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) in rat serum or cell culture supernatant were detected by enzyme-linked immunosorbent assay.The study protocol was approved by the Animal Ethics Committee of the First People's Hospital of Chenzhou (No.2020086).Results:Compared with control group, the IOP was higher in high IOP group at 1, 2 and 3 weeks after cauterization, and the differences were statistically significant (all at P<0.05). The retinal tissue was clear with the RGCs in a single layer arrangement in the control group.In the high IOP group and the high IOP+ siNC group, the RGCs layer was loose and the inner plexiform layer was thin.The inner plexiform layer was thickened in high IOP+ siNLRP12 group compared with high IOP group, and the RGCs layer was loose in the high IOP+ siNLRP12 group and the high IOP+ siNLRP12+ rrcaspase-1 group.The number of RGCs in control group, high IOP group, high IOP+ siNC group, high IOP+ siNLRP12 group and high IOP+ siNLRP12+ rrcaspase-1 group was 119.31±23.25, 89.19±16.98, 88.87±13.92, 109.33±10.25 and 92.89±12.58, respectively, showing a statistically significant overall difference ( F=201.932, P<0.001). The number of RGCs was lower in the high IOP group, high IOP+ siNC group, high IOP+ siNLRP12 group and high IOP+ siNLRP12+ rrcaspase-1 group than the control group, higher in the high IOP+ siNLRP12 group than the high IOP+ siNC group, and lower in the high IOP+ siNLRP12+ rrcaspase-1 group than the high IOP+ siNLRP12 group, and the differences were statistically significant (all at P<0.05). The relative expressions of caspase-1 and cleaved-caspase-1 proteins and the concentrations of TNF-α and IL-1β in the retinal tissue were higher in high IOP group, high IOP+ siNC group, high IOP+ siNLRP12 group and high IOP+ siNLRP12+ rrcaspase-1 group than control group, higher in high IOP+ siNLRP12 group than high IOP+ siNC group, and higher in high IOP+ siNLRP12+ rrcaspase-1 group than high IOP+ siNLRP12 group (all at P<0.05). Relative expression levels of caspase-1 and cleaved-caspase-1 protein were increased in rrcaspase-1 group and siNC+ rrcaspase-1 group compared with control group, and relative expression levels of NLRP12, caspase-1 and cleaved-caspase-1 protein were decreased in siNLRP12+ rrcaspase-1 group compared with control group (all at P<0.05). The relative mass concentrations of TNF-α and IL-1β were increased in rrcaspase-1 group, siNC+ rrcaspase-1 group and siNLRP12+ rrcaspase-1 group compared with the control group (all at P<0.05). Relative expression levels of NLRP12, caspase-1 and cleaved-caspase-1 proteins and relative mass concentrations of TNF-α and IL-1β in siNLRP12+ rrcaspase-1 group were lower than those in siNC+ rrcaspase-1 group (all at P<0.05). Conclusions:Knockdown of NLRP12 can reduce the inflammatory response and retinal injury induced by high IOP by inhibiting the activation of caspase-1.

OBJECTIVETo examine the influence of China's economic reforms on population health and regional mortality rates.

METHODSLongitudinal study measuring the mortality trends and their regional variations. Using data from the three most recent national censuses, we used the model life table to adjust the mortality levels within the population for each census, and to calculate life expectancy. We then examined the variation in patterns of mortality and population health by economic status, region and gender from 1980-2000.

RESULTSLife expectancy varied with economic status, province, and gender. Results showed that, although life expectancy in China had increased overall since the early 1980s, regional differences became more pronounced. Life expectancy for populations who live in the eastern coastal provinces are greater than those in the western regions.

CONCLUSIONDifferences in life expectancy are primarily related to differences in regional economic development, which in turn exacerbate regional health inequalities. Therefore, it is necessary to improve economic development in less developed regions and to improve health policies and the public health system that address the needs of everyone.
