ABSTRACT
Objective:To explore the effect of continuous obstetric-pediatric cooperative nursing on anxiety, depression and the parenting sense of competence in NICU premature mothers.Methods:Totally 140 mothers of NICU preterm infants in hospital from January 2018 to December 2018 were selected and randomly divided into the control group and intervention group according to the method of random number table, and each group 70 cases. The control group received the routine nursing mode in obstetrics and paediatrics and the intervention group received the continuous obstetric-pediatric cooperative nursing based on routine nursing. To compare the anxiety level, depression level, the score of parenting sense of competence, hospitalization days of preterm infants, the outpatient rate and the readmission rate of preterm infants within 1 months of discharge between two groups.Results:The levels of anxiety and depression of the mothers of premature infants in the intervention group during hospitalization ,1 week after discharge and 1 month after discharge were (43.17±6.89), (8.96±2.67), (34.65±6.87), (7.65±1.92), (34.97±6.06), (6.29±1.54) points, lower than control group (47.03±8.06), (10.97±3.34), (45.44±7.72), (9.43±2.61), (41.46±7.26), (8.28±2.23) points, the differences between the two groups showed statistical significance ( t value was 2.331-6.097, P<0.05). The two dimensions of parenting efficacy and parenting satisfaction were (31.47±4.97), (43.38±4.21) points, which were higher than (25.91±5.42), (39.43±5.91) points of the control group, there were significant statistical differences among the two groups ( t value was -6.314 and -4.528, P<0.01). The hospitalization days of premature infants, outpatient and readmission rate within 1 month of discharge were (13.25±3.27) days, 8.57% (6/70), 2.86% (2/70), which were shorter or lower than (15.59±2.79) days, 24.29% (17/70), 12.86% (9/70) in the control group, the differences were statistically significant ( t value was 2.909, χ2 values were 6.295, 4.834, P<0.05). There were significant statistical differences among interaction effect, time effect and intergroup effect ( F values were 4.921-99.310, P<0.05). Conclusion:Obstetrical-pediatric cooperative nursing can effectively to lower the anxiety and depression level of preterm mothers, improve the parental competence, promote the mental health of preterm mothers, and ultimately shorten hospital days and decrease the rate of outpatient and readmission of premature infants, which is conducive to preterm infants′ rehabilitation.
ABSTRACT
Background:Patients with acute gouty arthritis experienc severe pain and often have concomitant limited joint movement. High-dose intake of anti-inflammatory analgesics often results in adverse reactions, such as nausea, vomiting, and diarrhea, and might increase the risk of gastrointestinal bleeding. In order to reduce the adverse reactions by oral intake, local use of externally useddrugs with the same active ingredients as the oral intake is an option in clinical practice. However, externally useddrugs take effect slowly and efficacy to reduce painful feelingis unsatisfactory. Therefore, it is demanding to develop a safe and effective treatment plan. In this regard, researchers have put up a hypothesis. The skin of the human body has a dense stratum corneum, which is difficult for externally used drugs to penetrate effectively; if the keratin barrier of the skin around affected joints can be broken without further damaging the skin, externally applied drugs may safely and effectively alleviate the local symptoms of acute gouty arthritis. The nano plum blossom needle is made of a modern new material. The needle body is thin and the diameter of the needle tip is only 300 nm. The needle is used clinically to break through the keratin barrier of the human skin and promote the absorption of external medicine. Therefore, this trial was designed to preliminarily evaluate the safety and effectiveness of using the nano plum blossom needle for the introduction of diclofenac diethylamine emulgel in the treatment of acute gouty arthritis.Methods:A randomized controlled trial including 83 patients with acute gouty arthritis was conducted, who was assigned to three groups, the intervention group, control group 1, and control group 2 in a ratio of 2:2:1, respectively. The nano plum blossom needle was used for the introduction of diclofenac diethylamine emulgel in the intervention group; the nano plum blossom needle was used as a placebo along with the local use of diclofenac diethylamine emulgel in control group 1; and the nano plum blossom needle was used alone in control group 2. The treatments were applied once a day until the pain was completely relieved and the course of treatment lasted up to 7 days. The primary outcome measurement was the visual analog scale for evaluating the degree of pain. The secondary outcome indicators included scoring of the symptoms and signs with comprehensive consideration of the joint skin color, local tenderness, and degree of joint motion, the time and dose of emergency medication usage during trial, and adverse events.Discussion:This trial couldprovide preliminary evidence for evidence-based practice of using nano plum blossom needle transdermal drug delivery technology for diclofenac diethylamine emulgel for the treatment of acute gouty arthritis, and provide a reference for sample size calculation and experimental design of future clinical trials verifying the effectiveness and safety of such a technical scheme in a larger target population.Registration information:This study has been registered in the China Clinical Trial Registry Centerwith the registration code of ChiCTR-IOR-17012154.

ABSTRACT
A fluorescent molecular probe R6G-Flu was prepared by modifying fluorescein onto Rhodamine 6G.The probe could be used to recognize Al3+ specifically, and the detection limit could reach as low as 10-8 mol/L.After addition of Al3+ (10 μmol/L) to the probe, the solution showed a color change from colorless to pink, and green fluorescence was observed under the UV irradiation, which could be perceived by the naked eye.By measuring the fluorescence emission intensity of R6G-Flu at different pH, the probe could also be used to determine pH in acidic pH range (3.00-6.00) and basic pH range (8.00-10.50).The detection results of Al3+ and pH indicated that the R6G-Flu was a dual-functional fluorescent molecular probe.
ABSTRACT
Objective To investigate the relationship between hepatic fibrosis stage and clinical serum fibrosis markers in patients with chronic hepatitis B (CHB).Methods Liver puncture biopsy was performed in 189 CHB patients.The serum levels of hyalyronic acid (HA),laminin (LN),procollagen Ⅲ (PCⅢ),collagen Ⅳ (Ⅳ C),liver function and peripheral blood routine were detected simultaneously. The comparison, correlation and regression analysis were performed based on different fibrosis stages (S).Results From SO to S4 group,levels of PC Ⅲ,γ-glutamyl transpeptidase (γ-G-T),total bilirubin (TBil),protein electrophoresis γ-globulin (Ely-γ) and prothrombin time (PT) were progressively elevated,the differences were statistically significant (F value was 3.325,6.218,2.958,10.160 and 7.028,P＜0.05),while cholinesterase (CHE),total protein (TP),albumin (Alb) and platelet (PLT) were progressively declined,the differences were also statistically significant (F value was 15.984,3.768,14.919 and 4.737,P＜0.05).The differences of LN,IVC,ALT and AST between groups were statistically significant (F value was 4.618,2.795,2.649 and 3.199,P＜0.05).Fibrosis stages (s) was positively correlated with LN,PCIII,ALT,AST,TBil,γ-GT,Ep-γand PT (r=0.200,0.306,0.172,0.273,0.153,0.402,0.415,0.269,respectively);while it was negatively correlated with CHE,TP,Alb and PLT (r=-0.502,-0.208,-0.413,-0.390,respectively);I.N,AI.T,CHE,PLT and Ep-γ were the independent risk factors which affecting hepatic fibrosis stages.Conclusions Liver fibrosis stage in histopathology was correlative in certain degree with the serum markers of hepatic fibrosis,liver function,and blood routine examination.Combined analysis of clinical data may be used to early diagnose hepatic fibrosis non-invasively.
