Objective To investigate the clinical characteristics and treatment of acute postrenal acute renal dysfunction associated with ceftriaxone.Methods Twenty-five cases of the ceftriaxione-associated acute postrenal renal insufficiency were reviewed.There were 16 males and 9 females,mean age 28years.The serum contents of BUN and Cr were ( 18.6 ± 7.0) mmol/L and (635.5 ± 248.7 ) μmol/L,respectively.All patients were divided into two groups depending on the therapy:11 patients accepted the drug therapy (alkalinization of the urine,antispasmodic,etc) and 14 patients accepted the intraureteral cannula.The clinical characteristics and the treatment effect were compared between the 2 groups.Results The patients of the intraureteral cannula group ( 1.4 ± O.7 d) went to hospital earlier than the drug therapy group (3.0 ± 1.4 d) ( P =0.045 ) after the symptom of oliguria or anuria appeared.There were no significant differences in serum creatinine,urea nitrogen,and the age between the 2 groups ( P ＞ 0.05 ).All the patients were cured after treatment.There were no significant differences in recovery time (2.9 ± 1.1 d and 3.2 ± 1.2 d,P =0.963) and hospitalization time (7.0 ±2.3 d and 5.9 +3.9 d,P =0.568) between the 2 groups.Conclusions The acute renal failure associated with ceftriaxone should have high attention.The prompt medical attention,including the intraureteral eannula and the drug therapy,can both achieve the satisfying curative effect.

ObjectiveTo evaluate the usefulness of an ultrasonography-based method to examine quadriceps femoris contracting. MethodsThe thickness of bilateral rectus femoris (RF) and vastus intermedius (VI) and the cross-sectional area (CSA) of RF was measured in 10 healthy subjects （n=20） in a relaxed position and 3 isometric contraction states using ultrasonography by two examiners. The date was compared with paired t test. Half of these subjects （n=10） were also measured with MRI at rest. The date was also compared with paired t test. ResultsThere was no significant difference between MRI and static compound ultrasonography, nor between two examiners. There was a significant difference (P<0.05) in thickness of RF and VI between relaxed and isometric contraction conditions. There was no significant difference among isometric contraction conditions. There was no significant difference among measurements of RF-CSA. Conclusionultrasonography shows good validity and reliability in measuring quadriceps shape.

Objective:To investigate the clinic-cytology and histopathology of non-Hodgkin lymphoma (NHL) in breasts. Mothods:Twelve cases of NHL of the breast were studied by fine-needle aspiration biopsy (FNAC), histopathology and immunohistochemistry, and whose clinical data were analysed at the same time. Results:In 12 cases of NHL, 3 cases were T-cell NHL and 9 cases were B-cell NHL. Cytologically, the T-cell NHL cells were mostly arranging in diffuse patterns. The tumor cells were oval and pleomorphism. Some of them had distorted nucleus and thin nuclear envelope.The nucleus showed irregular course chromatin and visible nueleoic. Histopathologically, some of the tumor cells distributed around the blood vessels, and there was an obvious phenomenon of “blood-vessel-closing”. B-cell lymphoma cells were arranginy in diffuse pattern, and showed round and ellipse in shape with a clot and course granular chromatin and visible nueleoic and karyoknesis. Lymphoepithelia lesions were seen. Immunohistochemistry showed that CD3, CD43, and CD 45RO in T-cells NHL were positive.CD20, CD74 and CD79a in B-cells NHL were negative. CK, EMA, ER and PR in NHL were all negative. Conclusion:NHL of breast is extremely rare, and its definite diagnosis depends on various examination methods.

Abstract: Objective To compare the differences in the expression of interleukin-8 (IL-8) and signal transducer and activator of transcription 3 (STAT3) among three groups of individuals: patients with multi-drug resistant tuberculosis (MDR-TB), patients with drug-susceptible tuberculosis (DSP-TB), and healthy controls. By analyzing the differences between these groups, the study seeks to provide a reference basis for clinical auxiliary diagnosis of new type tuberculosis. Methods The differences in mRNA expression profiles of chip from peripheral blood mononuclear cells (PBMCs) among three groups were analyzed. MDR-TB and DSP-TB patients were selected as study subjects, with healthy individuals serving as a control group, and the serum IL-8 concentration of each group was measured using an ELISA assay to compare differences between groups. Additionally, PBMCs from all groups were isolated and total RNA was extracted for analysis of IL-8 and STAT3 mRNA expression using quantitative real-time PCR(Q-PCR). Differences in STAT3 protein expression among the groups were also compared by Western blot assay. Results The serum IL-8 concentration in the MDR-TB and DSP-TB groups was significantly higher than that in the healthy control group, with a statistically significant difference (P<0.05). The relative expression level of IL-8 mRNA in PBMCs of the MDR-TB group and DSP-TB group was also significantly higher than that of the healthy control group, with a statistical significance (P<0.05). Both Q-PCR and Western Blot results revealed that the expression of STAT3 in the healthy, DSP-TB and MDR-TB groups sequentially increased, presenting statistically significant differences between the groups (P<0.05), consistent with the mRNA chip results. Conclusions The expression of IL-8 in active tuberculosis patients (ATB) is significantly increased, which can be used as a marker to distinguish ATB from healthy populations. The changes of STAT3 concentration not only serve as a reference for the diagnosis of ATB but can also distinguish between DSP-TB and MDR-TB populations. The combined detection of IL-8 and STAT3 holds promise as a clinical auxiliary diagnostic basis for different tuberculosis patients.

Objective: To explore latent classes of college students aggressive behavior and its correlations with family care and the meaning of life among college students. Methods: A cross sectional questionnaire survey was conducted among 5 094 students from three universities in Xinxiang City in December 2021, using Aggression Questionnaire (AQ), Family APGAR Index (APGAR), and the Meaning in Life Questionnaire (MLQ). Results: Aggressive behavior of college students was classifed into three potential categories:low aggressive behavior group (26.4%), moderate aggressive behavior group (48.5%), and high aggressive behavior group(25.1%). There were significant differences in latent classes of aggressive behavior among college students by gender, physical flexibility, exercise frequency, and sleep status ( χ 2=63.95, 169.86, 125.76, 325.24, P <0.01). There were significant differences in the sense of life meaning and the degree of family care among the 3 potential categories of aggressive behavior ( F=113.47, 231.82, P <0.01). The multivariate Logistic regression analysis showed that the sense of meaning of life ( OR =0.96, 95% CI =0.96-0.97) and family care ( OR =0.83, 95% CI =0.81-0.84) were significantly associated with three classes of aggressive behavior ( P <0.01). Conclusion Aggressive behavior among college students is associated with gender, exercise frequency, sleep status, meaning of life, family care, and physical flexibility. School, family and society should actively pay attention to students psychological characteristics and to provide corresponding support for aggressive behavior prevention and intervention.

Objective? To explore the effects of scenario simulation combined with case share on fall prevention education in elderly patients. Methods? A total of 80 elderly patients admitted in Shaanxi Provincial People's Hospital from January 2016 to December 2017 were selected by convenient sampling and equally divided into two groups according to the random number table. Patients in the control group received conventional fall prevention education, while patients in the observation group received fall prevention education which combined scenario simulation and case share. Falls of patients, effects of education and satisfaction were compared between the two groups. Results? The incidence rate of falls in the observation group during hospitalization was 10.0%, while that in the control group was 20.0% (χ2=4.325; P＜0.05); the knowledge of fall prevention, the awareness of fall prevention and fall prevention compliance scored (86.3±5.2), (84.2±5.3) and (91.3±8.4), higher than those in the control group (t=9.981, 9.040, 12.872; P＜ 0.01), which were (76.3±4.4), (75.2±3.4) and (71.3±5.1) respectively. The satisfaction with nursing in the observation group was 95.0%, higher than that in the control group (χ2=4.201; P＜0.05). Conclusions? Fall prevention education which combines scenario simulation and case share can effectively enhance the awareness of fall prevention, reduce the incidence of falls and improve the satisfaction with nursing in the patients, which is worth promoting in clinical practice.

Objective To evaluate the impact of the professional knowledge and skills of hospital attendants on the quality of hospital care and its training effect. Methods200 accompanists from a Class ⅢGrade A hospital in Xi'an from January 2017 to December 2018 were selected as the subjects by convenient sampling. 100 accompanists from January to December 2018 were used as observation groups to develop their professional knowledge and skills training; 100 accompanists who did not carry out professional knowledge and skills training during from January to December 2017 were the control group. The professional knowledge and skills, quality of care were compared between the two groups before and after training. ResultsThe scores of basic care, daily life care, psychological care, functional rehabilitation, cleansing care, and communication in the observation group were higher than those in the control group, and the differences between the two groups were statistically significant (P＜ 0.05). After training, the patients' health education awareness rate, complication rate, safety incident rate, and satisfaction were better than before training, and the differences were statistically significant (P＜0.05). ConclusionsDue to the limitation of professional knowledge and skill level, the comprehensive quality of hospital accompanists needs to be improved. Strengthening the training of accompanists can not only improve the comprehensive quality of the accompanists themselves, but also improve the quality of hospital care, which is beneficial to the health and rapidity of the medical care industry.

Objective:To investigate the clinical effect of high diffusion sensitivity coefficient(high b value)diffusion-weighted imaging(DWI),dynamic contrast-enhanced magnetic resonance imaging(DCE-MRI)combined with tumor carbohydrate antigen 125(CA125)in judging the nature of ovarian lesions.Methods:A total of 100 patients with ovarian lesions who were treated in Nantong Haimen People's Hospital from April 2020 to April 2022 were selected for retrospective study.All of them underwent CA125,DWI,DCE-MRI and pathologically qualitative examination.According to the pathological results,58 patients with malignant lesions of ovarian were divided into malignant group and patients with benign lesions of ovarian were divided into benign group.The CA125 levels of the two groups were analyzed and compared,and the results of the receiver operating characteristics(ROC)of different detection methods(DWI with high b value+CA125,DCE-MRI+CA125,DWI with high b value+DCE-MRI+CA125)also were analyzed and compared.Results:The CA125 index of the malignant group was significantly higher than that of the benign group,with a statistically significant difference(t=29.357,P＜0.05),and the CA125 positive rate of the malignant group was significantly better than that of the benign group,with a statistically significant difference(x2=34.456,P＜0.05).The apparent diffusion coefficient(ADC)value[(0.91±0.18)×103mm2/s]of the malignant group was significantly less than that[(33±0.21)×103mm2/s]of the benign group,while the contrast agent volume conversion constant(Ktrans),rate constant(Kep)and the extracellular space volume ratio outside of blood vessels(Ve)of the malignant group were significantly higher than those of the benign group,with significant differences(t=16.863,9.686,10.205,P＜0.05),respectively.The diagnostic accuracy,sensitivity,negative predictive value and positive predictive value of DWI with high b-value+DCE-MRI+CA125 examination method were higher than those of DWI with high b-value + CA125 or DCE-MRI+CA125 examination method in diagnosing malignant ovarian tumors.There were not significant differences in various indicators between DCE-MRI+CA125 examination method and DWI with high b-value +CA125 examination method(P＞0.05).ROC curve analysis showed that the area under curve(AUC)of the DWI with high b-value +DCE-MRI+CA125 examination method was the best(AUC=0.920).Conclusion:The combined examination method of DWI with high b-value + DCE-MRI + CA125 has better overall diagnostic efficiency,which can improve the screening ability of clinical diagnosis for malignant ovarian tumors.It has a certain clinical application value.
