ABSTRACT
Objective To investigate the pathogenesis of superficial mycosis among naval trainees, and observe the efficacy of a novel antifungal drug. Methods A questionnaire survey was conducted on the onset, medication and recurrence of superficial fungal infection among the trainees from January, 2020 to July, 2020. At the same time, the new antifungal drug sulconazole nitrate spray was provided for treatment and the drug efficacy was observed. Results The participants generally lacked understanding and attention to superficial fungal infections. The incidence rate of superficial fungal infection was 52%, of which 76.2% of patients had recurrence of superficial fungal infection. The sulconazole nitrate spray showed great effect against these infections. Conclusion The trainees should understand the causes of superficial fungal infection through health education and seek medical treatment and medication in time. The cure rate of superficial fungal infections could only be improved through the collaborative management of the school, hospital, and trainees to reduce the impact of these infections on naval trainees’ work and life.
ABSTRACT
Objective To provide the reference resource for the safe clinical use of the compound of diphenhydramine hydrochloride and caffeine by observing its effects on the nervous system, cardiovascular system and respiratory system in experimental animals. Methods Single dose of the compound of diphenhydramine hydrochloride and caffeine was given to animals orally. The effects on climbing ability of mice and blood pressure, electrocardiogram, respiration rate and amplitude in beagle dogs were observed and recorded. Results With the dosage of the compound of diphenhydramine hydrochloride and caffeine (diphenhydramine hydrochloride / caffeine ratio is 1/2.4) at 51, 102, 204 mg/kg, there was no significant effect on the climbing ability in mice. With the dosages of 14.2, 28.3, 56.6 mg/kg for male Beagle dogs and 5.66, 14.2, 28.3 mg/kg for female Beagle dogs, no significant effects were observed in systolic blood pressure, diastolic blood pressure, mean arterial pressure, heart rate, ECG（P wave, R wave , T wave, QRS time, PR interval, QT interval）, respiratory rate and amplitude. Conclusion Under the experimental conditions, single oral dose of the compound of diphenhydramine hydrochloride and caffeine has no significant effect on the nervous system, cardiovascular system and respiratory system in experimental animals. Those results suggest that the compound of diphenhydramine hydrochloride and caffeine is a safe agent for clinical use.
ABSTRACT
Objective To investigate the medication adherence of military academy students with superficial mycoses. Methods A 8-item Morisky medication adherence scale (MMAS) was modified into 7-item scale to evaluate the compliance of antifungal drugs in the sick students. The reliability and validity of the scale were analyzed. Results A total of 243 questionnaires were collected, of which 242 were valid questionnaires. 90.08% of the students took topical medication and 8.68% were treated both with topical and systematic combination. High, medium and low medication adherence rates as assessed by the modified MMAS were 9.09%, 23.97% and 66.94%, respectively. The reliability analysis showed that the internal consistency coefficient (Cronbach’s α ) was 0.781，and the adjusted Cronbach’s α was 0.790, indicating the high reliability of the scale. The KMO value was 0.798, and the Bartlett’s spherical test value was 440.866, P=0.000. One factor was extracted by exploratory factor analysis. The factor loadings of the items were all above 0.5. Therefore, the high convergent validity was good. Conclusion The modified MMAS has good reliability and validity and is applicable for the evaluation of medication compliance for superficial mycoses. In this study, the military students have a low level of medication adherence for superficial mycoses. Effective measures should be taken to help students strengthen their daily medication management and improve compliance.
ABSTRACT
Background The incidence of myopia is gradually increasing,and how to choose a better corrective method of myopia for the best visual demand is very important.Objective This study was to compare visual quality of implantable collamer lens (ICL) implantation with femtosecond laser in situ keratomileusis (FSLASIK) for moderate and high myopia using double-pass optical quality analysis system (OQAS).Methods A non-randomized controlled clinical trail was performed.Fifty-two eyes with-4.00 to-9.00 D of 26 consecutive patients were included in NO.1 Hospital of Xi'an from January 2015 to January 2016.Twenty-four eyes of 12 patients with the corneal thickness ＜500 μm received ICL implantation as ICL group and 28 eyes of 14 patients which corneal thickness was ≥500 μm underwent FS-LASIK surgery as FS-LASIK group.The demography was matched between the two groups (all at P＞0.05).All the patients were followed-up for 3 months after surgery.The preoperative best corrected distance visual acuity (BCDVA),spherical equivalent (SE),postoperative uncorrected distance visual acuity (UCDVA),BCDVA and SE were examined and compared between two groups.The parameters from OQAS were evaluated and intergrouply compared,including the objective scattering inders (OSI),modulation transfer function (MTF) cut off frequency,Strehl ratio and OQAS values under the contrast of 100％,20％ and 9％ (OV100,OV20,OV9).Results The postoperative BCDVA was not significantly different from preoperative UCDVA in both ICL group and FS-LASIK group (-0.04±t0.10 vs.0.05±0.12;-0.07±0.12 vs.0.00±0.12) (t=3.128,2.358,both at P＞0.05).No statistically significant differnces were found in SE,UCDVA and BCDVA after operation between ICL group and FS-LASIK group (t =1.292,0.900,-0.653,all at P＞0.05).OQAS examination showed that MTF cut off,OSI,Strehl ratio,OV100 were not significantly different after operation between ICL group and FS-LASIK group (t=-2.032,-1.440,-0.224,all at P＞0.05).The postoperative OV20 and OV9 were 0.82±0.14 and 0.80±0.21 in the ICL group,which were significantly higher than those in the FS-LASIK group(0.59±0.15 and 0.47±0.13) (t =4.105,4.702,both at P＜0.05).Conclusions Both ICL implantation and FS-LASIK provide good optical and visual quality for moderate to high myopic eyes,and ICL appears to have a better visual quality in comparison with FS-LASIK under the contrasts of 20％ and 9％.
