OBJECTIVESTo investigate the role of focal adhesion kinase (FAK) in the pathogenesis of cardiac hypertrophy induced by hypertension.

METHODSUsing immunofluorescent labeling, confocal microscopy and Western blotting, the expression and subcellular localization of FAK in the cardiac myocytes of left ventricle were determined in 2, 6, 12, and 18 month-old rats with spontaneously hypertensive heart failure (SHHF) along with age-matched control Wistar-Kyoto (WKY) rats.

RESULTSThere was no significant difference of FAK expression between 2 month-old SHHF and WKY rats (50.5+/-6.9 vs. 49.8+/-5.0, n=6, P>0.05). In contrast with the control groups, the expression of FAK significantly increased in 6, 12 and 18 month-old SHHF rats (130.6+/-3.0 vs. 47.3+/-1.3, 144.7+/-5.4 vs. 46.4+/-3.1, 141.4+/-9.8 vs. 48.5+/-2.2, each groups n=6, P<0.05) with FAK protein primarily cumulated in the intercalated disks and nuclei.

CONCLUSIONSFAK may play a role in the cell signaling transduction leading to cardiac hypertrophy, presumably through regulations of hypertrophic gene transcription and RNA processing.

Objective To study the effect of systemic group music therapy (SGMT) on social living function and life quality in patients with schizophrenia. Methods By systematic sampling, 160 patients were divided into intervention group (80 patients) and control group (80 patients).Patients in the intervention group were treated by SGMT, and the control group was treated by general care.Comparison was made before intervention and 18 months after intervention on the following:scores of social living function as determined by the Activity of Daily Living Scale (ADL), Social Disability Screening Schedule (SDSS), and Social Maladjustment (SOC) scale.The WHO quality of Life-BREF scale was used to analyze score changes of patients′ life quality. Results ADL, SDSS and SOC scores of the patients in intervention group were significantly lower than those in control group (P values all 0.05).In comparison of the life quality scores, physical health, mental health and social relationship scores were higher in intervention group than those in control group(P values all < 0.05).There was no significant difference between two groups in environment scores(P>0.05). Conclusion Implementation of SGMT intervention can efficiently improve patients′ social living function and quality of life.

OBJECTIVE: To study the clinical features of catch-up growth of body height after kidney transplantation in children and related influencing factors. METHODS: A retrospective analysis was performed from the chart review data of 15 children who underwent kidney transplantation in Guangzhou Women and Children's Medical Center from July 2017 to November 2019. According to whether the increase in height standard deviation score (ΔHtSDS) in the first year after kidney transplantation reached ≥0.5, the children were divided into a catch-up group with 8 children and a non-catch-up group with 7 children. According to whether final HtSDS was ≥-2, the children were divided into a standard group with 6 children and a non-standard group with 9 children. The features of catch-up growth of body height and related influencing factors were compared between groups. RESULTS: The data showed that median ΔHtSDS was 0.8 in the first year after transplantation, which suggested catch-up growth of body height. There was a significant difference in HtSDS between the non-catch-up and catch-up groups (P<0.05). Baseline HtSDS before transplantation was positively correlated with HtSDS at the end of follow-up (r=0.622, P<0.05) and was negatively correlated with ∆HtSDS in the first year after transplantation (r=-0.705, P<0.05). Age of transplantation and mean dose of glucocorticoid (GC) per kg body weight were risk factors for catch-up growth after kidney transplantation (OR=1.23 and 1.74 respectively; P<0.05), while baseline HtSDS and use of antihypertensive drugs were independent protective factors for catch-up growth (OR=0.08 and 0.18 respectively; P<0.05); baseline HtSDS and ΔHtSDS in the first year after kidney transplantation were influencing factors for final HtSDS (β=0.984 and 1.271 respectively; P<0.05). CONCLUSIONS Kidney transplantation should be performed for children as early as possible, growth retardation before transplantation should be improved as far as possible, and multiple treatment methods (including the use of GC and antihypertensive drugs) should be optimized after surgery, in order to help these children achieve an ideal body height.
