Objective To investigate the effect of comprehensive nursing intervention and evaluate its role in the entire clinical course of in the treatment of children with severe burns. Methods A total of 60 children with 1-5 years old with clinical diagnosis of severe burns were randomly divided into experimental group and control group by random digits table method, 30 cases in each group. The control group received routine burn care. The experimental group received comprehensive nursing interventions on the basis of routine burn care and the intervention time covered the entire course of treatment. During hospitalization, the recovery and family social system were evaluated by anxiety scales and social support scales combined with the cure rate and hospitalization of children. Results Before intervention, the score of Anxiety Rating Scale was high in both groups of families, while Social Support Scale was lower, the difference was not statistically significant between the two groups (P>0.05). After intervention, the score of Anxiety Rating Scale and was Social Support Scale were (52.31±7.81), (31.52± 5.48)points in the experimental group, and (62.51 ± 6.52), (23.62 ± 5.62) points in the control group, and there were significant differences (t=5.491 3, 5.512 5, P<0.01). The length of stay was (18.34±3.58) d in the experimental group, and (21.82 ± 4.23) d in the control group, and there was significant difference(t=3.439 6, P<0.05). The cure rate was 93.33%(28/30) in the experimental group, and 56.67%(17/30) in the control group, and there was significant difference(χ2=10.755 6, P<0.05). Conclusions The comprehensive nursing intervention can provide comprehensive refinement of the overall care in children and their families, promote physical and psychological rehabilitation of children with severe burns, and repair their family and social support systems. The comprehensive nursing intervention has far-reaching implications for the rehabilitation of children with severe burns.

Objective To improve the quality of the management of the elderly patients with cancer in Sichuan province,and to understand the attitudes and perspectives of elderly surgeons and oncologists for the management and treatment of elderly patients with cancer.Methods A face-toface questionnaire interview was conducted with oncologists (n 64) and geriatricians (n =64).128 physicians were involved in this study.Results The cancer management and therapeutics were deemed appropriate at present by 9.38％ (6/64)of the geriatricians and 25.00％ (16/64)of the oncologists.The 39.06％ (25/64) of geriatricians used to notice geriatric syndromes,while 81.25％ (52/64)of oncologists never concerned about the geriatric syndrome(P=0.011).As for the causes of the therapy-associated toxicity,oncologist versus geriatrician payed an attention to malnutrition (100.00％ vs.100.00％ in both groups),to mobility disorders(65.63％ vs.65.63％,84/128 in both groups),to cognitive impairment/mood disorder (89.06％ in geriatrician group vs.75.00％ in oncologist group,P=0.038).For the factors affecting treatment decisions,a physical ability attention (oncologists vs geriatricians:70.31％ vs.92.19％;P =0.002),and comorbidity (oncologists vs geriatricians:62.50％ vs.79.69％,P =0.032) had statistically significant difference.In addition,lack of geriatrics knowledge was also reported by more oncologists.However,one hundred percent of participants wanted very much to cooperate with each other in their clinical work.When responding to the clinical scenario,the 10.94％ (7/64)of geriatricians and 32.81％ (21/64)of oncologists chose modified treatment for 65-74 years old patient with cancer(P =0.003).When the age of the patients was 75-84 years old,only 12.50 ％ (8/64) of geriatricians prefer end-of-life care,while 31.25 ％ (20/64) of oncologists chose it (P =0.010).Conclusions Selection of treatment decisions in the elderly patients with cancer affect by ageing.Both oncologists and geriatricians are concerned with the elderly patients with cancer,ageing syndrome,total sickness and functional status.And these doctors support an establishment of a multi disciplinary team cooperation for the elderly patients with cancer.Therefore,the establishment of mutual cooperation between the two professionals is necessary and feasible.

Objective: To explore the effects of multidisciplinary comprehensive intervention in integrated treatment of patients with extremely severe burns. Methods: One hundred and ten patients hospitalized in our center from July 2013 to August 2017 met the criteria for inclusion in this study, and their medical records were retrospectively analyzed. According to the medical model at that time, 56 patients hospitalized from July 2013 to July 2015 received routine comprehensive treatment led by doctors, and they were included in the conventional intervention group. From August 2015 to August 2017, 54 patients were treated with integrated multidisciplinary interventions performed by a team consisting of physicians, intensive care nurses, burn nurses, intravenous infusion nurses, wound stoma nurses, and rehabilitation therapists, and they were included in the integrated intervention group. Acute Physiological and Chronic Health Assessment Ⅱ (APACHE Ⅱ) scores on admission and 4 weeks after treatment, incidences of pressure injury, wound sepsis, lung infection, and catheter-related infection during hospitalization, length of stay in intensive care unit (ICU) and total length of hospital stay, and Abbreviated Burn Specific Health Scale (BSHS-A) scores at discharge and 3 months after discharge were analyzed. Data were processed with t-test and chi-square test. Results: The APACHE Ⅱ scores of patients in the two groups were close on admission (t=0.573, P>0.05). Four weeks after treatment, the APACHE Ⅱ scores of patients in the two groups were obviously lower than those on admission within the same group (t=5.697, 4.853, P<0.01), and the score of the integrated intervention group was obviously lower than that of the conventional intervention group (t=2.170, P<0.05). No pressure injury was observed in patients of any group during hospitalization. The incidences of wound sepsis, lung infection, and catheter-related infection of patients in the integrated intervention group were 18.5% (10/54), 3.7% (2/54), and 9.3% (5/54), respectively, significantly lower than 42.9% (24/56), 21.4% (12/56), and 26.8% (15/56) of the conventional intervention group, χ²=4.073, 6.075, 3.962, P<0.05. The length of stay in ICU of patients in the integrated intervention group was (50±5) d, obviously shorter than (62±4) d of the conventional intervention group (t=2.852, P<0.01). The total length of hospital stay of patients in the integrated intervention group was (115±8) d, obviously shorter than (140±7) d of the conventional intervention group (t=16.885, P<0.01). At discharge and 3 months after discharge, the scores of BSHS-A, physical function, psychological function, and general health status of 50 patients in the integrated intervention group were significantly higher than those of 48 patients in the conventional intervention group (t=2.886, 3.126, 2.416, 2.544, 2.033, 3.471, 2.588, 2.210, P<0.05 or P<0.01), while the scores of social function of patients in the two groups were close (t=1.570, 1.350, P>0.05). Conclusions Integrative treatment of patients with extremely severe burns by multidisciplinary comprehensive intervention can significantly alleviate the severity of burns, reduce the incidences of wound sepsis, lung infection, and catheter-related infection, shorten the length of stay in ICU and total length of hospital stay, and improve the quality of life.

OBJECTIVETo investigate the value of serum IgA/C3 ratio in the diagnosis of IgA nephropathy and explore its relationship with the clinicopathological features of the patients.

METHODSSixty-six patients with IgA nephropathy, 111 with other glomerular diseases, and 40 healthy control subjects without kidney disease were tested for serum IgA and C3 levels using CRM470 adjusted standardized immune turbidimetric method, and the IgA/C3 ratio was calculated. According to Oxford and Lee's classification criteria, we analyzed the pathological grades of the renal biopsy samples from patients with IgA nephropathy. The ROC curve was used to assess the value of serum IgA and IgA/C3 ratio in predicting IgA nephropathy.

RESULTSPatients with IgA nephropathy had an elevated serum IgA/C3 ratio than those with other glomerular diseases and the control subjects, with an area under the ROC curve of 0.776. An elevated serum IgA/C3 ratio was not found to significantly correlate with the pathological grade of renal biopsy samples in patients with IgA nephropathy.

CONCLUSIONIn the absence of renal biopsy findings, serum IgA/C3 ratio can help in the diagnosis of IgA nephropathy.

Objective:To investigate the association between the Doppler variables of the ophthalmic artery with the severity of preeclampsia(PE).Methods:Systematic literature was searched between January 1995 and March 2023 in PubMed,Web of Science,Embase,and the Cochrane Library.Studies comparing ophthalmic artery Doppler variables,including peak systolic velocity(PSV),end-diastolic velocity(EDV),resistive index(Rl),pulsa-tility index(PI),and peak ratio(PR,the ratio of the flow velocity of the second peak to that of the initial peak)in patients with PE,severe preeclampsia(sPE),and healthy pregnant women were included.The random-effects model was adopted as the method of pooled analysis,and the I2value was used to assess heterogeneity.The pooled standardized mean difference(SMD)with 95％confidence interval(CI)was used to estimate the associa-tion between ophthalmic artery Doppler variables and PE patient's characteristics.Results:Eight retrospective studies were eventually included in this Meta-analysis.Our pooled results suggested that compared with PE ca-ses,sPE patients had lower PI levels(SMD-0.56,95％CI-0.92～-0.20,P=0.000),higher EDV levels(SMD 0.47,95％CI 0.12～0.83,P=0.028)and higher PR levels(SMD0.96,95％CI 0.13～1.78,P=0.023).Howev-er,there was no significant difference between PE and sPE patients about the PSV and RI(P=0.361,P=0.626).Conclusions:This review demonstrates that ophthalmic artery Doppler variables(PI,EDV and PR)could be useful for predicting PE and PE development(especially in identifying sPE),which in turn may help the practitioner in the management of these complicated cases and in taking early necessary precautions.

Objective: To explore the influence of cluster nursing intervention on inadequate drainage in vacuum sealing drainage (VSD) for inpatients in burn unit. Methods: From October to December 2016, 60 patients, aged (43.6±2.8) years admitted to our department, receiving VSD treatment and conforming to the inclusion criteria, were included in the routine nursing group, and among the patients, 37 cases were male and 23 cases were female. From May to July 2017, 58 patients, aged (44.2±3.2) years admitted to our department, receiving VSD treatment and conforming to the inclusion criteria, were included in the cluster nursing group, and among the patients, 36 cases were male and 22 cases were female. The patients′ medical records were retrospectively analyzed. After VSD treatment, patients in routine nursing group received routine nursing, and patients in cluster nursing group received cluster nursing. A cluster intervention group was formed and headed by a chief surgeon. The cluster nursing plan was formulated and implemented strictly from the following six aspects of material preparation, negative pressure value control and negative pressure mode setting, drainage tube nursing, semi-permeable membrane reinforcement, standardizing changing process and timing of drainage capsule, and health education. During VSD treatment, the incidence of inadequate drainage, reasons of inadequate drainage and the occurrences, occurrences of inadequate drainage of wounds in different types and sites, and satisfaction of patients in two groups were observed and calculated. The patient satisfaction items included procedure of drainage capsule replacement, the method of tube fixation, the content and form of health education. Data were processed with independent sample t test and chi-square test. Results: (1) During VSD treatment, the incidence of inadequate drainage of patients in routine nursing group was 43.33% (130/300), which was significantly higher than 17.24% (50/290) in cluster nursing group (χ²=43.350, P<0.01). (2) During VSD treatment, the incidences of inadequate drainage caused by blockage of drainage tube due to scabbing of drainage, low negative pressure, air leakage of semi-permeable membrane, improper changing process of drainage capsule, shedding, compression, reversal of drainage tube of patients in cluster nursing group were 7.93% (23/290), 4.48% (13/290), 1.72% (5/290), 1.03% (3/290), and 2.07% (6/290), respectively, significantly lower than 16.67% (50/300), 11.67% (35/300), 4.33% (13/300), 4.00% (12/300), and 6.67% (20/300) in routine nursing group (χ²=10.379, 22.951, 4.832, 7.840, 7.399, P<0.05 or P<0.01). (3) During VSD treatment, the incidences of inadequate drainage of burn wounds, trauma wounds, pressure ulcer, venous ulcer in lower limbs, and diabetic foot of patients in cluster nursing group were significantly lower than those in routine nursing group (χ²=17.835, 6.809, 9.478, 4.939, 8.631, P<0.05 or P<0.01). During VSD treatment, the incidences of inadequate drainage of wounds in different types of patients in the same group were close (χ²=0.434, 0.057, P>0.05). (4) During VSD treatment, the incidences of inadequate drainage of wounds in limbs, trunk, buttocks, and sacrococcyx of patients in cluster nursing group were significantly lower than those in routine nursing group (χ²=31.892, 9.588, 4.939, 4.549, P<0.05 or P<0.01). During VSD treatment, the incidences of inadequate drainage of wounds in different wound sites of patients in the same group were close (χ²=0.071, 0.069, P>0.05). (5) The satisfaction scores in changing process of drainage capsule, method of tube fixation, content and form of health education of patients in cluster nursing group after VSD treatment were significantly higher than those in routine nursing group (t=5.166, 4.471, 7.958, 8.975, P<0.01). Conclusions Cluster nursing intervention on patients receiving VSD treatment could reduce the incidences of inadequate drainage of wounds in different types and sites caused by various reasons. It also can improve patient satisfaction.
