Efficacy of CO2 dot matrix laser combined with 595 nm pulsed dye laser on cesarean section skin scar / 中华医学美学美容杂志

Objective To investigate the clinical efficacy of CO2 lattice laser combined with 595 nm pulsed dye laser in the treatment of cesarean section skin scar.Methods A total of 60 patients with cutaneous scar after cesarean section in our hospital from June 2015 to October 2017 were enrolled.The patients were divided into observation group and control group according to the order of hospitalization.Each group had 30 cases.Both CO2 lattice and 595 nm pulsed dye lasers were used in study group.Only CO2 lattice laser was used in control group.Vancouver scar scale (VSS) and adverse reactions were analyzed after treatment in both groups.Results The two groups were compared at 3 months and 6 months after treatment.The VSS scores of the study group were (52.00± 1.31) and (3.81±1.38),which was significantly lower than that of the control group (6.30±1.21) and (5.00± 1.38).The difference was statistically significant (t =3.175,3.35,P ＜0.05).There were no significant differences in adverse reactions between the two groups (P＞0.05).Conclusions CO2 dot laser combined with 595 nm pulsed dye laser for the treatment of cesarean section skin scar is more effective than CO2 dot matrix laser alone.

The effects of surface bonding on the compressive strength of different calcium hydroxide products / 实用口腔医学杂志

Objective:To explore the effects of surface bonding on compressive strength of chemically-cured(Dycal) and light-cured (Calcimol LC) calcium hydroxide.Methods:32 experimental specimens were prepared and divided into 4 groups(n =8):Group A,Dcyal without surface bonding;Group B,Calcimol LC without surface bonding;Group C,Dycal with surface bonding;Group D,Calcimol LC with surface bonding.German Zwick universal electronic testing machine was used to test the compressive strength of the specimens.Results:The average compressive strength value of group A,B,C and D was (110.48 ± 19.9),(162.6 ±7.8),(136.8 ± 17.2) and (223 ± 31.1) MPa respectively.Among them,the compressive strength of Group D was the highest (P ＜ 0.05).Compressive strength value of group B was higher than that of group A (P ＜ 0.05).No statistical difference was detected between other groups.Conclusion:The compressive strength of Light-cured Calcium Hydroxide is higher than that of chemically-cured Calcium Hydroxide.Surface bonding treatment can improve the compressive strength of Light-cured Calcium,no apparent effects can be produced on chemicallycured Calcium Hydroxide.

Evaluation of the effect of emergency nursing pathway applied in the treatment of patients with questionable sources / 中国实用护理杂志

Objective To investigate the effect of emergency nursing pathway in emergency treatment of patients with questionable sources. Methods A clinical nursing pathway for the treatment for patients with questionable sources was formulated. From February to December 2014, 78 patients with questionable sources treated by clinical nursing pathway were selected as the observation group. From January to November 2013, 75 patients with questionable sources treated by routine nursing care methods were selected as the control group. Differences were compared in duration of staying in the emergency department, nursing complication and fees paid rate between the two groups. Results For the average duration of staying in the emergency department, the observation group was lower than that in the control group [19.35%(9.08) vs. 19.90%(25.20), P< 0.05)]. For the nursing complication rate, the observation group was significantly lower than that of the control group [1.28%(1/78) vs.10.67%(8/75), P<0.05]. For the fees paid rate, the observation group was significantly higher than that in the control group [64.10%(50/78) vs. 33.33%(25/75), P<0.01]. Conclusions By the emergency nursing pathway, emergent patients with questionable sources will be treated with satisfactory result in the shortest time.

A cohort investigation of the allergen and pathogenesis in the patients with allergic rhinitis from three hospital of Guangdong Province / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To study the pathogenesis of the patients with allergic rhinitis diagnosed by Skin Prick Test (SPT), especially about the epidemiologic data of the involved allergens.@*METHOD@#The data was collected from 958 patients referred to the listed three allergy center and subsequently diagnosed as allergic rhinitis by SPT.@*RESULT@#The intermittent mild type was more prevalent in male patients (40.5%); comparably the intermittent moderate type in female patients (70.0%); in the infant patients the moderate-severe type dominated (73.7%). The positive results of SPT comprised mainly of Dermatophagoides pteronyssinus (Der. p, 98.3%), Dermatophagoides farinae(Der. f, 96.8%), and Blomia tropicalis (Blot, 73.8%). Only 1.7% of the patients was allergic to single allergen, in contrary ,the majority of patients were allergic to multiple allergens. The positive rate to Der. p and Der. f was reversely increasing with age of the patients; and contrarily the number of positive allergens was increasing along with the age of the patients. The allergy to outdoor allergen was less common, and the positive rate in skin prick test was lower than the previously reported rate in North China ,such as timothy (3.9%), birch (2.7%), ragweed (2.0%), and mugwort (1.2%).@*CONCLUSION@#Dust Mite is the predominant allergen for patients with allergic rhinitis in Guangdong province; and the positive rate to outdoor allergen is lower than that in North China.

Causes Analysis of Urinary Tract Infection with Association of Catheter and Countermeasures / 中华医院感染学杂志

OBJECTIVE To discuss the liable episodes of the urinary tract infection with relation of catheter and propose the prevention measures.METHODS We radomly selected 536 patients with catheter.The urinary tract infection,as well as related factors were observed in patients with indwelling catheter.RESULTS The catheter replacement time interval as well as indwelling time were the risk factors,when the indwelling catheter time was 1-3 days,the CAUTI rate was 10.3%,if the time was ≥10 day,the CAUTI rate was 97.6%.Additionally the antibiotic use would cause dysbacteriosis which also easily caused the urinary tract road infection.CONCLUSIONS When taking care of the patients who had catheter,we should grasp the indications of catheterization,reduce the indwelling time,apply the effective nursing measures and correct choice of antibiotics,that can evidently control the infection.

Ventilator-associated Pneumonia:Causes and Nursing Measure / 中华医院感染学杂志

OBJECTIVE To explore the reason and the nursing measure of the ventilator-associated pneumonia(VAP).METHODS Fifty five patients with VAP after mechanical ventilation were statistically analyzed and the pathogens were detected,at the same time to carry out comprehensive nursing measure.RESULTS After effective nursing measuring the motality due to VAP was decreased and the successful rescue rate was increased.CONCLUSIONS The VAP associates with various risk factors,but it can be prevented and controalled via overall reasonable and effective nursing measure.
