Results About 1550 nursing papers were published , of which the number of authors whose paper was published in core journals was 216 , the number of papers published in core journals was 378, and 38 authors published more than 3 papers (17.6%). The core journals papers published rate in different position was statistically significant (P<0.01). The papers published journals were concentrated in nursing class. Dominated the first 3 places in the list of core journals paper number of departments were department of nursing , cancer center and operation room, respectively. Conclusion In order to improve the nursing scientific research level of nursing staff, it is necessary to establish a theoretical system of scientific knowledge training , formulate a long-term effective mechanism in paper management , focus on scientific research talent introduction and training and mobilize the nursing research enthusiasm of nursing staff.

PURPOSE: The aim of this study was to evaluate the effects of reflective trainings for nursing students on their critical thinking disposition. METHODS: A total of 157 senior undergraduate nursing students sampled from Hainan Medical University in China participated in this study in 2014. They were randomly divided into experimental and control groups. The experimental group students were provided the reflective training during their entire 12-month clinical internship, whereas students in the control group were requested to keep their reflective diaries but without a formal training. Before and after the intervention, nursing students' critical thinking disposition was rated using the Chinese version of Critical Thinking Disposition Inventory (CTDI-CV). RESULTS: Before the start of the intervention, the critical thinking disposition scores of the two groups had no significant differences. At the end of the intervention, it was found that the experimental students performed better in each subscale of CTDI-CV. These include the search for truth, open mind, analytical ability, systematic ability, critical thinking, self-confidence, curiosity, and cognitive maturity. By summing the scores of all categories, the results showed that the experimental group had a significantly higher total score than that of the control group (p ≤ .044). Evaluating the score difference in each function indicated that there was a range of improvements on the critical thinking disposition because of the reflective training intervention. CONCLUSION: Reflective training during the internship period improves nursing students' disposition of critical thinking and promotes their readiness for their clinical practices in the rapidly increasing demands of the healthcare field.

OBJECTIVE: To study the molecular pathogenesis of SLC26A4 mutations associated with inner ear malformations including large vestibular aqueduct syndrome (LVAS), Mondini dysplasia and inner ear malformations but not accompanied with LVAS. METHOD: DNA sample and clinical material were obtained from 14 sporadic LVAS probands, six Mondini dysplasia probands and seven inner ear malformations excluding IVAS probands. SLC26A4 gene mutation was analyzed by direct sequencing for its 20 coding exons. GJB2 gene and also mt12SrRNA were analyzed by direct sequencing. RESULT: In 14 cases of LVAS, two mutations were detected in 12 patients (85.7%, either homozygous or compound heterozygous mutations), and one mutation was found in two patients (14.3%). In six cases of Mondini dysplasia, two mutations were detected in all of patients (100%). No mutation could be found in the seven cases of other inner ear abnormalities not accompanied with LVAS. No pathogenic mutation was detected in all of these 27 probands in GJB2 gene and mt12SrRNA 1555/1494T. CONCLUSION We have shown that LVAS and Mondini dysplasia closely correlate with SLC26A4 gene. No mutation was detected in seven probands of inner ear malformations not accompanied with LVAS. We should study the molecular pathogenesis of this disease in depth.

Objective To investigate the correlation among fractional exhaled nitric oxide (FeNO), child asthma control test(C-ACT) and lung function in asthmatic children and its clinical significance. Methods A total of 108 cases of asthmatic children in the Affiliated Hospital of Qingdao University from June 2016 to September 2018 were recruited. Forty-seven cases (47.44%) were in acute onset, 40 cases(40.37%) were in chronic persistent, and 21 cases (21.19%) were in paracmasis. FeNO, lung function and C-ACT score were measured, and the correlation among them was analyzed. Results The level of FeNO in acute onset patients and chronic persistent patients had no significant difference:(44.18 ± 25.47)×10-9 vs. (46.98 ± 27.50)×10-9, P>0.05, but the level of FeNO in paracmasis patients was lower [(24.43 ± 10.71) × 10-9], compared with that of acute onset patients and chronic persistent patients, there were significant differences (P < 0.01). The scores of C-ACT in three groups had significant difference (P < 0.01), and there were significant differences between any two groups (P <0.01). The levels of forced expiratory peak flow rate measured value as a percentage of predicted value (FEV1%) and forced expiratory volume and forced vital capacity ratio in the first second (FEV1/FVC) in acute onset patients were significantly lower than those in chronic persistent patients and paracmasis patients (P <0.01), and there were no significant differences between chronic persistent patients and paracmasis patients (P＞0.05). Conclusions Compared with lung functions and C-ACT, FeNO is a good biomarker to evaluate the airway inflammation of asthmatic children.

Objective:To analyze the clinical phenotypic characteristics and therapeutic effect of cutaneous anthrax patients in Ningxia Hui Autonomous Region (referred to as Ningxia).Methods:A retrospective analysis was conducted on the medical records of 76 confirmed patients with cutaneous anthrax in three prefecture level hospitals in Ningxia from 2017 to 2022. According to the length of hospital treatment, the patients were divided into a disease course ≥7 d group ( n = 54) and a disease course < 7 d group ( n = 22), and the clinical phenotypic characteristics (including patients' general condition, clinical symptoms, and laboratory tests) and therapeutic effects (the effect of hormone use and the choice of antibiotics) of the two groups were analyzed by methods such as χ 2 test. Results:Among 76 patients with cutaneous anthrax, males accounted for 81.6% (62/76) and females accounted for 18.4% (14/76), with a statistically significant difference in gender composition ratio (χ 2 = 5.71, P = 0.017). Among the 76 patients, 73 caces (96.1%) achieved clinical cure. There was no statistically significant differences between the groups in clinical characteristics such as temperature, pain, pruritus, edema, and site of onset ( P > 0.05). There were no statistically significant differences between groups in laboratory tests such as blood routine, liver function, hypersensitive C-reactive protein, secretion culture, PCR, etc. ( P > 0.05). There was a statistically significant difference in the distribution of edema resolution time between patients using hormone or not (χ 2 = 17.01, P = 0.002). There was no statistically significant difference in the distribution of disease course between different antibiotic treatment regimens when using hormone (χ 2 = 5.43, P = 0.143). There was a statistically significant difference in the distribution of disease course between different antibiotic treatment regimens when no using hormone (χ 2 = 108.46, P < 0.001). Conclusions:The majority of cutaneous anthrax patients in Ningxia from 2017 to 2022 are males. Early use of hormones can affect the duration of edema in patients. For patients who have not received hormone therapy, different treatment plans can affect the patient's course of disease.

Objective To investigate the imaging findings of oblique vaginal septum syndrome and its diagnostic value.Methods Clinical and radiographic data of 13 patients with oblique vaginal septum syndrome were analyzed retrospectively and relevant literatures were reviewed.All 13 patients underwent ultrasonography examination preoperatively,and 8 of them underwent MRI examination,and 3 patients underwent CT examination as well.The position of the oblique septum,the size of the cavity in the rear of oblique septum, the positional relationship between the cavity in the rear of oblique septum and the cervix,and the concomitant changes of the uterine appendages and urinary system were analyzed.Results The ultrasonography and MRI examinations all manifested as uterus didelphys,cervix duplex,double vagina and obstructed hemivagina,and oblique septum originated from the middle of cervix duplex and attached to one side of the vaginal wall,shielding the ipsilateral cervix;oblique vaginal septum was on the right side in 4 cases and on the left side in 9 cases;the average volume of the cavity in the rear of oblique septum in 6 cases of type Ⅰ was 255 mL,and the average volume in 6 cases of type Ⅱ was 74 mL,and the volume in 1 case of type Ⅲ was 56 mL;2 cases were combined with ipsilateral hematosalpinx and 1 case was combined with a chocolate cyst of ipsilateral ovary;12 cases were accompanied with ipsilateral renal agenesis and 1 case was accompanied with ipsilateral renal hypoplasia.CT examinations of 3 cases all presented as uterus didelphys,a cystic hypodensity lesion under unilateral cervix and ipsilateral renal agenesis.Conclusion Imaging findings of oblique vaginal septum syndrome are quite characteristic. Ultrasonography,CT and MRI examinations have certain value for accurate diagnosis of the disease.

Objective:To investigate the epidemiological characteristics and influencing factors of scoliosis among primary and middle school students in Dali Bai autonomous prefecture.Methods:A total of 176,729 students aged 6-18 years from 380 primary and secondary schools in eight counties of Dali Bai Autonomous Prefecture were screened for spinal health by visual method, Adams forward bend test and scoliometer measuring the angle of trunk rotation from September to November 2021. The angle of trunk rotation ≥5° or visual method retest positive was used as a positive standard to confirm suspected scoliosis population. Demographic data of the screening population including name, gender, age and ethnicity were collected. The average altitude of the community or village committee in the screening area was recorded. Binary logistic regression analysis was used to screen the influencing factors of scoliosis.Results:There were 176,729 people planned to complete the screening. A total of 140,026 people were actually completed screening with completion rate 79.23%. A total of 3,190 (2.28%) suspected scoliosis positive people were detected. The detection rate of female was 2.52%, which was higher than that of male 2.03% (χ 2=37.18, P<0.001). The detection rate of 10-18 years old group was 2.90%, which was higher than that of 6-9 years old group 0.70% (χ 2=620.79, P<0.001). There was a significant difference in the detection rate among different age groups from 6 to 18 years old (χ 2=1,451.00, P<0.001). The detection rate of Han population was 2.67%, which was higher than that of non-Han population 2.15% (χ 2=31.06, P<0.001). In non-Han population, the detection rate of Bai population was 2.07%, which was lower than that of non-Bai population 2.26% (χ 2=4.02, P=0.045). Trend chi-square test showed significant difference in the detection rate of scoliosis among the general population, 10-18 years old population and 6-9 years old population in the altitude <1,500 m, 1,500-1,599 m, 1,600-1,699 m, 1,700-1,799 m, 1,800-1,899 m, 1,900-1,999 m, 2,000-2,099 m, 2,100-2,199 m, 2,200-2,299 m and ≥2,300 m groups (χ 2=249.02, 195.64, 24.46, P<0.05). Binary logistic regression analysis showed that the risk of scoliosis was lower in males than that in females ( OR=0.82, P<0.001). The risk of scoliosis was increased in 10-18 years old compared with that in 6-9 years old ( OR=0.12, P<0.001). The risk of scoliosis was low in Bai population compared with that in Han populations ( OR=0.75, P<0.001). The altitude ≥2,000 m was a risk factor ( OR=1.52, P<0.001). Conclusion:The detection rate of suspected scoliosis in primary and middle school students in Dali Bai Autonomous Prefecture was 2.28%. Female, aged 10-18 years, Han populations, and residence in altitude ≥2,000 m might be the risk factors for scoliosis.
