Objective:To explore the application effect of family participatory multisensory support programme based on the theory of enriched environment on preterm infants and their mothers in neonatal intensive care unit (NICU).Methods:A historical comparative study was conducted. One hundred and sixteen pairs of preterm infants and their mothers admitted to NICU, Affiliated Hospital of Youjiang Medical University for Nationalities from March to October 2023 were selected by convenience sampling method and divided into control group and experimental group according to the time of admission. The control group was given routine care, while the experimental group implemented a family participatory multisensory support programme based on the enriched environment theory on the basis of the control group. The amplitude-integrated electroencephalography (aEEG) scores and the Chinese version of Parent-Child Interaction Feeding Scale (PCI-FS-C) scores before and after intervention, the Gesell developmental quotients at 40 weeks and 3 months of gestational age, the Chinese version of Maternal Attachment Inventory (CMAI) scores of preterm mothers on the day of discharge and 1 and 3 months after discharge were compared between the two groups.Results:A total of 105 pairs of premature infants and their mothers were included, 52 premature infants of control group, 29 males and 23 females; 53 premature infants of experimental group, including 32 males and 21 females. Before intervention, there were no significant differences in aEEG scores and PCI-FS-C scores between the two groups (all P>0.05). After intervention, the scores of aEEG and PCI-FS-C in the experimental group were (10.91 ± 2.18) and (12.62 ± 1.32) points, respectively, which were higher than (9.67 ± 1.94) and (10.42 ± 1.45) points in the control group, and the differences were statistically significant ( t=3.06, 8.15, both P<0.05). The Gesell developmental quotient were (54.03 ± 9.73), (55.17 ± 11.19), (57.20 ± 11.04), (53.60 ± 9.74), (55.17 ± 10.11) at 40 weeks of gestational age, and (77.15 ± 11.55), (76.62 ± 9.90), (72.76 ± 11.90), (81.47 ± 10.01), (76.51 ± 12.25) at 3 months of gestational age, respectively, which were higher than the control group (49.70 ± 9.07), (49.06 ± 8.61), (52.41 ± 9.01), (49.28 ± 8.78), (50.07 ± 12.52), and (71.10 ± 11.87), (69.02 ± 12.53), (65.77 ± 12.24), (75.08 ± 11.08), (68.63 ± 10.89), the differences were statistically significant ( t values were 2.30-3.49, all P<0.05). The CMAI scores of preterm mothers in the experimental group were (82.81 ± 12.85), (87.70 ± 10.29), (95.91 ± 8.76) points on the day of discharge and 1 and 3 months after discharge, respectively, which were higher than (68.71 ± 14.15), (82.04 ± 11.87), (90.98 ± 11.13) points of the control group, the differences were statistically significant ( t=5.35, 2.61, 2.52, all P<0.05). Conclusions:The family participatory multisensory support programme based on the theory of enriched environment can accelerate the maturation of brain electrical activity in preterm infants and promote brain function and neurobehavioural development; meanwhile, it improves maternal sensitivity and promotes the establishment of mother-infant attachment relationship in preterm infants.

Objective:To assess the relationship between basophil levels and mortality in patients with intra-abdominal infection.Methods:Information on patients with intraperitoneal infection admitted to the intensive care unit were extracted from the MIMIC database.A time-dependent Cox regression model was used to adjust for confounders associated with 28-day mortality.Propensity score matching(PSM)was used to balance the baseline differences be-tween groups with different basophil levels,and a restricted cube chart(RCS)was used to show the relationship between basophil count and 28-day mortality in patients with intra-abdominal infection.Results:A total of 4403 patients with intra-abdominal infection were enrolled in the MIMIC database.Patients with high basophil levels have lower mortality than those with low basophil levels.There was an L-shaped curve between basophil level and 28-day mortality,with a cut-off value of 0.47×109/L.Cox regression analysis showed that basophil levels were an independent protective factor for mortal-ity in patients with intra-abdominal infection after adjusting for potential confounders(HR=0.586,95%CI:0.443-0.769).Protective factors for death at basophil levels remained after PSM adjusted for potential confounders(HR=0.628,95%CI:0.470-0.832).Conclusion:Basophil level is an independent protective factor for mortality in patients with intra-abdominal infection,and basophil levels should be dynamically monitored to better evaluate the prognosis of patients.

Objective To investigate whether PKCβ inhibitor can alleviate RIRI by regulating macrophage phenotype.Methods Rats in the renal ischemia-reperfusion injury(RIRI)model group underwent right nephrec-tomy followed by a 60-minute clamping of the left renal pedicle.In the experimental group(Inhibitor+RIRI),PKCβ inhibitors were administered orally one day prior to surgery.All rats were euthanized 24 hours post-surgery for the collection of blood and left kidney samples.Renal function,tissue morphology,and the expression levels of renal tubular injury marker KIM-1,renal papilla injury marker RPA-1,macrophage subtype markers,and inflammatory factors were evaluated.Results PKCβ inhibitors alleviated renal ischemia-reperfusion injury in rats.PAS staining revealed marked tubular damage in kidney sections from the RIRI group,whereas kidney inflammatory cell infiltra-tion and renal tubular injury scores were significantly reduced in the Inhibitor+RIRI group following PKCβ inhibitor treatment(all P<0.05).The expression levels of Cr,BUN,KIM-1,and RPA-1 were markedly elevated in the RIRI group compared to the Sham and Inhibitor+RIRI groups(all P<0.05).After PKCβ inhibitor intervention,the expression levels of Cr,BUN,KIM-1,and RPA-1 were significantly decreased in the Inhibitor+RIRI group relative to the RIRI group(all P<0.05).Protein expression levels of iNOS,IL-2,and CD197 in the kidney tissue of the RIRI group were significantly higher than those in the Sham and Inhibitor+RIRI groups(all P<0.05).Compared with the RIRI group,the protein expression levels of iNOS,IL-12,and CD197 were significantly reduced in the Inhibitor+RIRI group following PKC β inhibitor intervention(all P<0.05).Additionally,the protein expression levels of Dectin-1,ARG-1,and CD163 were significantly higher in the Inhibitor+RIRI group than in the RIRI and Sham groups after PKCβ inhibitor intervention(all P<0.05).Conclusions PKCβ inhibitors can mitigate renal dysfunction,renal tubular injury,and the expression of injury markers in the renal tubules and renal papilla follow-ing ischemia-reperfusion.Additionally,PKCβ inhibitors play a role in modulating macrophage subtypes by reducing M1 macrophages and promoting polarization to M2,which leads to a decrease in pro-inflammatory factors and an increase in anti-inflammatory factors,ultimately facilitating kidney repair.

Objective To understand the current status of work-related musculoskeletal disorders (WMSDs) among operating room doctors,thereby analyzing its effect on mental health. Methods A total of 1013 doctors in the operating rooms of 30 hospitals in 24 provinces from September to December 2022 were selected by cross-sectional survey method. The domestic musculoskeletal disease questionnaire was used to investigate the occurrence of WMSDs in operating room doctors,the symptom check list-90 (SCL-90) was used to evaluate the psychological status of operating room doctors,the relationship between WMSDs related items and SCL-90 scores was analyzed,the correla-tion between the rest time of each shift and SCL-90 factors was analyzed by Pearson method,and the influencing factors of mental health of operating room doctors were analyzed by multivariate Logistic regression.Results A total of 1100 questionnaires were distributed and 1013 valid questionnaires were recovered,with an effective rate of 92.10％. The incidence of WMSDs among operating room doctors in the past 1 year was 95.06％. The body parts with incidences of WMSDs from high to low were as follows:waist (36.92％),neck (35.54％),shoulder (33.56％),and upper back (32.77％). In the past 1 year,the SCL-90 scores and total scores of patients with musculoskeletal pain in various body parts,keeping the same back posture for a long time while work,bending the back at the same time of turning frequently while working,bowing the head for a long time while working,and bending the knee for a long time while working were significantly higher than those who were without the above conditions (P<0.05). Shorter rest time of each shift and longer periods of keeping the same back posture were the risk factors for the development of mental illness in operating room doctors. Conclusion The incidence of WMSDs in operating room doctors is high,which can influence the mental health of operating room doctors. Therefore,operating room doctors should avoid keeping the same back posture for a long time,bending the back at the same time of turning frequently,bowing the head for a long time,and bending the knee for a long time while working,and increase the rest time of each shift,in order to improve the mental condition of the operating room doctors.
