PURPOSE: Meconium aspiration is assumed to be a risk factor for bacterial infection, and patients with meconium aspiration syndrome (MAS) are commonly treated with empiric antibiotics in clinical settings. However, little is known about the effectiveness of the empirical antibiotics treatment. Here, we compared the short-term clinical outcomes associated with empirical antibiotics treatment in non-ventilated cases of MAS. METHODS: A retrospective study was conducted on infants admitted with non-ventilated cases of MAS from March 2008 to September 2016. The infants enrolled in the study were divided into two groups based on the antibiotics treatment, and their clinical outcomes were compared. The incidence of sepsis during the hospitalization period and the incidence of delayed sepsis up to 3 months were evaluated. The effects of empirical antibiotic use on respiratory symptoms were evaluated, and the complications were compared. RESULTS: A total of 109 infants were evaluated, of which 61 (56.0%) received antibiotics and 48 (44.0%) did not receive antibiotics. No differences in clinical characteristics were noted between the two groups. However, the empirical antibiotics group showed a significantly higher mean of respiratory rates, C-reactive protein levels, and positive rates, as well as a significantly longer hospitalization period. In clinical outcomes, there were no differences in sepsis rates or respiratory support duration. Furthermore, there were no differences in complications. CONCLUSION: The empirical use of antibiotics did not affect the clinical outcomes in cases of non-ventilated MAS. The role of empirical antibiotics in these infants may need to be reevaluated.

Objective: To explore sarcoplasmic reticulum ryanodine receptor2 (RyR 2) expression and calcium releasing function in chronic heart failure (CHF) rabbits and to study the impact of long term valsartan treatment in relevant animals. Methods: HF model was established by volume overloading with pressure overloading in experimental rabbits. 27 rabbits were divided into 3 groups: Sham group, HF group and HF+valsartan group. n=9 in each group and the animals were treated for 7 weeks. Left ventricular structure, hemodynamic parameters, expression and functional changes of myocardiocyte sarcoplasmic reticulum RyR 2 were observed and compared among different groups. Results: Compared with Sham group, HF group had increased left ventricular mess index (LVMI), left ventricular end diastolic pressure (LVEDP) and decreased left ventricular shortening fraction, LVEF, all P<0.05. Compared with HF group, HF+valsartan group showed decreased LVMI, LVEDP and increased left ventricular shortening fraction, LVEF, all P<0.05. Sarcoplasmic reticulum RyR 2 expression and calcium releasing function were lower in HF group than Sham group, P<0.05; while they were both higher in HF+valsartan group than HF group, P<0.05. Conclusion: Long term application of valsartan could improve the cardiac function which might be related to increased myocardial sarcoplasmic reticulum RyR 2 expression and calcium releasing function in experimental CHF rabbits.

OBJECTIVE: An orogastric tube is used frequently in infants because infants are obligate nose breathers and nasogastric tubes can cause partial nasal obstruction. This study examined whether the presence of an orogastric tube could affect the swallowing parameters assessed by a videofluoroscopic swallowing study in infants with dysphagia caused by a variety of reasons. METHODS: Tests were conducted in 15 infants aged less than 150 days after birth who used an orogastric tube due to dysphagia. Two tests were conducted. The first was conducted with an orogastric tube inserted. Subsequently, the orogastric tube was removed with a 5-minute break before the second test. Skilled physiatrists then analyzed the recorded video. The number of sucks required for one swallow, abnormalities of the pharyngeal phase, and penetration-aspiration scales were evaluated. RESULTS: After removing the orogastric tube, the number of sucks required for one swallow reduced significantly (2.50±1.73 vs. 3.45±2.54, P=0.04). On the other hand, no statistical significance was observed in the results of the pharyngeal phase and penetration-aspiration scale (5.60±3.16 vs. 5.9±3.81, P=0.41) with and without the orogastric tube. CONCLUSION: These findings showed that the insertion or non-insertion of an orogastric tube might not affect the swallowing abnormalities in the pharyngeal phase and the risk of aspiration. In addition, an orogastric tube may have a negative effect on the swallowing function in the oral phase.

Objective To diagnose Kennedy's disease (KD) via molecular analysis of the androgen receptor gene with suspected KD.Methods Two patients with suspected KD were reported.We analyzed their clinical features and investigated the number of CAG repeats in the androgen receptor genes. Results Both of the patients were characterized by slow progression of predominant proximal and bulbar muscle weakness.Patient 2 had oligospermatism.Serum creatine kinase and triglyceride levels were found markedly increased.The exact number of CAG was 52 in patient 1 and 48 in patient 2,respectively.These 2 patients were finally diagnosed as Kennedy's disease through the analysis of androgen receptor gene by PCR and direct sequencing.Conclusions The method of molecular analysis for KD had been copied in China.The clinical and molecular biological features of 2 Chinese patients with KD had been discussed.KD is a neurodegenerative disorder by proximal limb muscular atrophy and weakness with lower motor neuron signs,bulbar involvement.Dyscrinism and metabolic abnormalities may also be observed.Gene analysis is the unique and reliable methods to diagnose KD.

OBJECTIVE: To study the effect of bronchopulmonary dysplasia (BPD) on lung function in preterm infants. METHODS: According to the presence/absence or the severity of BPD, 72 preterm infants were divided into non-BPD group (n=44), mild BPD group (n=15) and moderate BPD group (n=13). Lung function was assessed by plethysmography on days 7, 14 and 28 after birth. RESULTS: The preterm infants in the three groups had gradual increases in tidal volume per kilogram (TV/kg), functional residual capacity (FRC), ratio of time to peak tidal expiratory flow to total expiratory time (%T-PF) and ratio of volume to peak tidal expiratory flow to total expiratory volume (%V-PF) on days 7, 14 and 28 after birth, while there were gradual reductions in effective airway resistance per kilogram (Reff/kg) and respiratory rate (RR) (P<0.05). Compared with the non-BPD group on days 7, 14 and 28 after birth, the mild and moderate BPD groups had significantly lower TV/kg, FRC, %T-PF, and %V-PF and significantly higher Reff/kg and RR (P<0.05). On day 7 after birth, the moderate BPD group had significantly higher airway resistance, Reff/kg and FRC/kg than the mild BPD group (P<0.05). CONCLUSIONS There is a certain degree of pulmonary function impairment in preterm infants with BPD. Dynamic monitoring of lung function by plethysmography is useful for assessing lung development in the neonatal period in these infants.

Objective To observe the effect of recombinant human erythropoietin injection (RHEI) assisted with mild hypothermia on the clinical efficacy and safety of children with hypoxic-ischemic encephalopathy (HIE). Methods From January 2015 to December 2017, 110 children with HIE were treated in Shijiazhuang No.1 Hospital. Fifty-five children with routine treatment were taken as Western medicine routine treatment group. In addition, 55 children treated with mild hypothermia combined with RHEI were taken as mild hypothermia+RHEI group. Both groups were treated for 14 days and followed up for 10 months. The neonatal behavioral neurological assessment (NBNA) score, mental development index (MDI), psychomotor development index (PDI), myelin basic protein (MBP), S100B protein and neuron specific enolization enzyme (NSE), nerve growth factor (NGF), brain derived neurotrophic factor (BDNF), insulin growth factor-1 (IGF-1), growth hormone (GH), and differences in clinical efficacy in two groups were compared, and the occurrence of adverse reactions was observed. Results The NBNA, MDI, PDI, NGF (μg/L), BDNF (ng/L), IGF-1 (pg/L), and GH (pg/L) of two groups after treatment were higher than those before treatment (the Western medicine routine treatment group: 33.72±3.19 vs. 26.81±2.38, 78.95±5.51 vs. 71.39±4.24, 79.62±4.93 vs. 71.84±4.15, 123.74±22.98 vs. 104.29±15.36, 1 518.35±174.92 vs. 1 197.28±148.43, 38.25±4.96 vs. 23.16±2.87, 39.27±5.24 vs. 20.97±3.15; the mild hypothermia+RHEI group: 39.82±3.36 vs. 26.78±2.53, 84.13±6.29 vs. 71.34±4.27, 85.26±5.74 vs. 71.88±4.13, 145.28±27.52 vs. 104.72±15.41, 1 925.71±204.37 vs. 1 192.61±150.26, 57.94±6.62 vs. 23.13±2.91, 56.43±7.14 vs. 20.94±3.17), NSE (μg/L), MBP (μg/L) and S100B (μg/L) were lower than those before treatment (the Western medicine routine treatment group: 17.05±2.26 vs. 24.96±2.83, 9.71±1.85 vs. 23.14±3.37, 0.93±0.12 vs. 1.49±0.24; the mild hypothermia+RHEI group:12.48±1.94 vs. 25.03±2.81, 5.48±1.42 vs. 23.17±3.35, 0.61±0.07 vs. 1.51±0.25). After treatment, the changes of each index in the mild hypothermia+RHEI group were more significant than those in the control group [NABA:39.82±3.36 vs. 33.72±3.19, MDI: 84.13±6.29 vs. 78.95±5.51, PDI: 85.26±5.74 vs. 79.62±4.93, NSE (μg/L):12.48±1.94 vs. 17.05±2.26, MBP (μg/L): 5.48±1.42 vs. 9.71±1.85, S100B (μg/L): 0.61±0.07 vs. 0.93±0.12, NGF (μg/L): 145.28±27.52 vs. 123.74±22.98, BDNF (ng/L): 1 925.71±204.37 vs. 1 518.35±174.92, IGF-1 (pg/L):57.94±6.62 vs. 38.25±4.96, GH (pg/L): 56.43±7.14 vs. 39.27±5.24, all P < 0.05]. The total effective rate of mild hypothermia+RHEI group was significantly higher than that of Western medicine routine treatment group [94.55% (52/55) vs. 81.82% (45/55), P < 0.05]. There were no serious adverse reactions in the two groups. Conclusion RHEI assisted with mild hypothermia therapy can significantly improve the clinical efficacy and NBNA, MDI, PDI scores of HIE children, reduce the degree of brain injury, and improve the neurological function, with good safety.

Objective To study the effect of the rehabilitation nursing for the stroke patients with attention deficit. Methods Fifty stroke patients with attention deficit were divided into two groups: attention nursing group and control group. The attention nursing group received routine nursing and attention nursing care while the control group received rourine nursing care only. To compare the change of attention, the two groups were evaluated with the mini-mental state examination (MMSE), meaningless verbal test and arousal level test before and after one month's nursing care. Results The attention evaluation was significantly improved in the attention nursing group, but no change was found in the control group. The attention evaluation of the attention nursing group was significantly better than the control patients after one-month nursing. Conclusions The attention of the stroke patients with attention deficit can be improved by the attention nursing.
