Purpose To investigate the expression and clinical significance of the cell cycle inhibitors p16 protein and specific recogni-tion of viral replication intermediate TLR3 in the cervical intraepithelial neoplasia ( CIN) and cervical invasive carcinoma. Methods Immunohistochemical stain was used to detect the expressions of p16 and TLR3 in 19 cases of normal cervical epithelium ( NCE) , 62 cases of CIN, and 17 cases of cervical squamous cell carcinoma (SCC). Results The positive rates of p16 protein were 0, 72. 5%and 100% in NCE, CIN and SCC respectively in which the difference among those groups were statistically significant ( P<0. 01 ) . Similarly, the positive rates of TLR3 protein were 26. 3%, 87% and 100% in NCE, CIN and SCC respectively and the difference a-mong those groups was significant (P<0. 01). Furthermore, there was a significant and positive correlation between the expression of p16 and TLR3 (rs =0. 538, P<0. 01). Conclusion Increased expression is observed in CIN and SCC compared with NCE and the expression of p16 and TLR3 is associated with level of CIN. Those could provide certain experiment basis for the pathologica diagnosis of early cervical cancer.

Objective To study the imaging findings, clinical and pathological characteristics of langerhans cell histiocytosis(LCH)in limbs of children, and to improve the imaging diagnostic accuracy of LCH . Methods Imaging findings and clinical data of 12 patients with limbs LCH were analyzed retrospectively. X-ray examination was performed in 10 cases, while 9 cases underwent CT and 7 cases underwent MRI examination. All imaging findings were analyzed. Results Seven lesions were solitary, including 4 lesions in the tibia, 2 in the radius and 1in the ulna. Five cases had limbs lesion in multiple sites, which included 12 bone lesions in total, with 6 lesions in the femur, 3 in the humerus (1 case involved the epiphysis), 2 in the tibia and 1in the radius. The X-ray or CT images of the lesions showed osteolytic destruction and swelling of the bone, which was commonly associated with the reaction of periosteum. Eleven cases were with peripheral soft tissue swelling, and one case had soft tissue mass. The lesions showed low signal on T1WI and high signal or mixed signal on T2WI. Six cases were diagnosed as LCH at the first time and the other 6 cases were diagnosed as infectious lesions. Twelve cases were regularly followed up after the treatment, and the prognosis of the patients with single lesion was better. Conclusions LCH of limbs usually involves diaphyseal and metaphyseal bone. The imaging features include osteolytic destruction and swelling of the bone, with peripheral soft tissue swelling or mass of the soft tissue. Although LCH of limbs has some specific imaging features, it is difficult to differentiate it from malignant bone tumors. Multi-imaging modalities such as radiography, CT and MRI imaging may suggest the diagnosis and provide important information for evaluating prognosis.

BACKGROUND: Researches suggest that transient ischemic attack (TIA)can induce cognitive dysfunction, and cerebral blood flow and its distribution are hypothesized to be closely related to cognitive activities.OBJECTIVE: To investigate the alteration of cognitive function and provide insights into its relations with cerebral perfusion in TIA patients.DESIGN: A case-control study.SETTING: Departments of Geriatrics, Electrophysiology and Magnetic Resonance of Urumqi General Hospital of Lanzhou Military Area Command of Chinese PLA.PARTICIPANTS: Totally 35 male right-handed TIA patients aged 45-78 years with an average of (68.1±8.4) years were selected from the inpatients and outpatients in the Department of Geriatrics, Urumqi General Hospital of Lanzhou Command of Chinese PLA between January 2002 and June 2003. Another 33 healthy right handed male subjects aged 45-77 years with an average of (67.8±8.6) years coming for physical examination were recruited to serve as the control group.METHODS: Patients and control subjects were tested with event-related potentials (ERPs) and the scale of elderly cognitive function (SECF) to examine the orientation, learning and memory, span, recall 1 (association),long-term memory, naming of animals, calculation, classification, copying,language and recall 2 (relation). According to the T score transformation table, the original scores were transformed into T scores relative to the age to eliminate the impact of age, and also into T'score to eliminate the interference by the patients'education, so that cognitive function of the patients could be evaluated with T'score, and the lower the score, the poorer the cognitive function. Cases in the two groups were all tested, and TIA patients were also examined with magnetic resonance angiography (MRA).MAIN OUTCOME MEASURES: Results of ERPs, SECF and MRA.RESULTS: Of the 35 TIA patients and 33 control subjects all completed the trial. Examination of ERPs reveled significantly prolonged latency of P300 components of ERP in the TIA group [(336.2±34.2) ms] than that in the control group [(311.3±44.2) ms, P ＜ 0.05]. The scores of span, recall 1,long-term memory, naming of animals, calculation, and recall 2 in SECF in TIA group were all lower than those in control group (39.7±11.9 vs 47.4±12.0; 54.5±14.8 vs 61.8±14.5; 61.1±7.8 vs 64.7±1.7; 59.4±11.0 vs 64.7±8.8; 50.0±14.7 vs 58.1±14.2; 44.6±15.4 vs 53.2±17.8, t=4.151 0-7.292 8, P ＜ 0.05-0.01). MRA identified abnormalities in 33 of the 35 TIA patients (94%), manifested mainly by stenosis and occlusion involving the vertebral artery (54%, 19/35), bilateral anterior, middle and posterior cerebral arteries (40% ,28/70;59% ,41/70;47% ,33/70), basilar artery (5.71%, 2/35) and bilateral internal carotid artery (5.71%, 4/70) respectively.CONCLUSION: TIA patients are characterized by prolonged P300 latency with multiple cognitive impairments especially in memory and cerebral artery stenosis and occlusion as shown by MRA, suggests that TIA patients have persistent low cerebral perfusion and frequently, cognitive dysfunction in the presence of local blood supply disorder in the hemispheres.

Objective:To explore the factors affecting the antiviral treatment efficacy of acquired immunodeficiency syndrome (AIDS) patients.Methods:A total of 107 patients diagnosed with human immunodeficiency virus (HIV) infection in the clinic of Beihai People′s Hospital from January 2016 to June 2018 were selected.The patients were divided into two groups according to whether they voluntarily accepted traditional Chinese medicine treatment, including treatment group who received highly active anti-retroviral therapy (HAART) and traditional Chinese medicine prescription of Ping Gan Jie Du (42 cases), and control group who were only treated with HAART (65 cases). The virological and immunological responses were compared between the two groups at 48 weeks of treatment. The interleukin-28B (IL-28B) rs12979860 genotypes were measured by using the direct sequencing of polymerase chain reaction products. Logistic regression was used to analyze the influencing factors of antiviral efficacy in AIDS patients.Comparison between groups was performed by independent sample t test、matched sample t test or chi-square test. Results:At week 48 of treatment, 41 (97.62%) of the 42 patients in the HAART plus Ping Gan Jie Du group obtained virological response, while 58 (89.23%) of the 65 patients in the HAART group alone acquired virological response, which was not significantly different ( χ2=0.100, P>0.05). The numbers of CD4 + T lymphocytes increased at week 48 of treatment in the HAART plus Ping Gan Jie Du group and HAART group were (244.32±101.83)/μL and (211.56±112.50)/μL, respectively. The was no statistically significant difference ( t=1.522, P>0.05). Among the 92 patients with IL-28B CC genotype, 88 (95.65%) acquired virological response, while 11 of the 15 patients with non-IL-28B CC genotype acquired virological response, which was not significantly different ( χ2=0.394, P>0.05). And CD4 + T lymphocytes in patients with IL-28B CC genotype increased ((229.72±101.17)/μL), which was higher than that without IL-28B CC genotype ((173.40±89.64)/μL), with statistically significant difference ( t=2.028, P=0.045). Multivariate logistic regression analysis showed that baseline CD4 + T lymphocyte count≤200/μL, IL-28B CC genotype, and treatment plan including protease inhibitor were helpful to improve the antiviral efficacy. Conclusion:Baseline CD4 + T lymphocyte count ≤200/μL, IL-28B CC genotype, and protease inhibitor in HAART regimen are the influencing factors of antiviral efficacy in AIDS patients.

OBJECTIVETo investigate the correlation effects between single or combined administration of Calculus Bovis or zolpidem and changes of inhibitive neurotransmitter in rat striatum corpora.

METHODSampling from rat striatum corpora was carried out through microdialysis. The content of two inhibitive neurotransmitters in rat corpus striatum- glycine (Gly) and gama aminobutyric acid (GABA), was determined by HPLC, which involved pre-column derivation with orthophthaladehyde, reversed-phase gradient elution and fluorescence detection.

RESULTGABA content of rat striatum corpora in Calculus Bovis group was significantly increased compared with saline group (P < 0.01). GABA content of zolpidem group and Calculus Boris plus zolpidem group were increased largely compared with saline group as well (P < 0.05). GABA content of Calculus Bovis group was higher than combination group (P < 0.05). GABA content of zolpidem group was not significantly different from combination group. Gly content of Calculus Bovis or zolpidem group was markedly increased compared with saline group or combination group (P < 0.05).

CONCLUSIONContents of two inhibitive neurotransmitters in rat striatum corpora were all significantly increased in Calculus Bovis group, zolpidem group and combination group. The magnitude of increase was lower in combination group than in Calculus Bovis group and Zolpidem group, suggesting that Calculus Bovis promoted encephalon inhibition is more powerful than zolpidem. The increase in two inhibitive neurotransmitters did not show reinforcing effect in combination group, suggesting that Calculus Bovis and zolpidem may compete the same receptors. Therefore, combination of Calculus Bovis containing drugs and zolpidem has no clinical significance. Calculus Bovis shouldn't as an aperture-opening drugs be used for resuscitation therapy.

Methods The interconnection first aid APP was made.The emergency center and traffic command center were combined to participate in first aid. The traffic command center controls the traffic lights in real time to provide the optimal transportation path for the emergency patients.The first aid center carries out preliminary treatment,and shares the patient information to the hospital in real time to make the most suitable doctors waiting for the consultation. The therapeutic effects of patients with acute critical disease before and after the platform applied was compared. Results It has realized the tripartite information linkage between the hospital, the emergency center and the traffic command center. In the experimental group, the pre-hospital emergency response time,the hospital rescue time and the emergency success rate were(16.28±3.08)min, (17.89±5.84)min,87.85%(217/247),the control groups'pre-hospital emergency response time,the rescue time in hospital and the success rate of acute critical patients were(18.29±1.87)min,(24.84±1.69)min, 63.01% (138/219), the data of two groups were statistically significant (t=3.783, 5.745, χ2=5.404, P<0.05). Conclusions The establishment of pre-hospital and in-hospital first aid rapid linkage treatment platform of emergency patients can optimize the patient first aid survival chain, provide greater rescue opportunities for emergency patients.

Objective The experiment was designed to study the therapeutic mechanism of "Tong Tiao" acupuncture in the treatment of mammary gland hyperplasia (MGH) on the rat model.Methods A total of 75 healthy unpregnant female SD rats were randomly divided into six groups: blank, model, control group, vagus cutting therapy, sham operation, and vagus cutting with non-treatment group. All the groups except the blank group were prepared by MGH rat model. The vagus cutting therapy and vagus cutting with non-treatment group were treated by cutting the right cervical vagus nerve, while the sham operation group was treated by exposing the vagus nerve without any operation. All the treatment groups were treated with "Tong Tiao". The rat papillary height was measured. The breast tissue morphology and breast ultrastructure were observated. And the flow cytometry in rat peripheral blood T lymphocyte subsets CD3+, CD4+, CD8+, CD4+/CD8+ were calculated. Results Compared with the model group, the papillary height (1.22 mm ± 0.21 mm,1.24 mm ± 0.20 mmvs. 1.53 mm ± 0.16 mm) in the normal treatment and the sham treatment group decreased significantly the vagus cutting therapy and vagus cutting non-treatment group showed no difference (P>0.05). Compared with the model group, the Mammary gland morphology and ultrastructure in the normal treatment group, the sham operation group and the vagus cutting therapy groups were improved, but the vagus cutting non-treatment group showed on improvement. Compared with model group, the serum CD3+(61.5％ ± 10.5％, 61.1％ ± 12.4％, 59.8％ ± 11.8％vs. 57.7％ ± 9.4％), CD4+(37.2％ ± 8.9％, 37.9％ ± 10.9％, 36.1％ ± 12.2％ vs. 34.6％ ± 6.9％), CD4+/CD8+(1.59 ± 0.8, 1.58 ± 0.8, 1.38 ± 0.6vs. 1.23 ± 0.7) in the normal treatment group, the sham treatment group and vagus cutting therapy group, elevated significantly (P<0.01,P<0.05), while the vagus cutting non-treatment group showed no difference (P>0.05). Compared with model group, the serum CD8+ (24.2％ ± 11.3％, 24.5％ ± 10.6％,25.5％ ± 8.8％vs. 27.7％ ± 9.9％) in the normal treatment group, sham treatment group and vagus cutting therapy group decreased significantly lower (P<0.01,P<0.05), but vagus cutting non treatment group showed no difference (P>0.05). Conclusions the mechanism of acupuncture treatment for MGH may be related to the vagus nerve by regulating the CD3+, CD4+, CD8+ and CD4+/CD8+ levels of T lymphocytes.

ObjectiveTo investigate the current situation of the family members' first aid ability and training needs of the patients with acute myocardial infarction(AMI), so as to provide basis for the development of first aid training programs for family members of AMI patients. MethodsUsing convenience sampling method, 310 family members of Acute ST Elevation myocardial infarction(STEMI) patients admitted to the Emergency Department of Second Hospital of Jilin University from January to December 2017 were selected as subjects. Self-designed Questionnaire was used in the study, which included the basic information of the AMI patients' family members as well as their first aid ability and the training needs on first aid. ResultsThe 310 family members of the AMI patients achieved the highest accurate rate (54.5%) from "first aid medication for AMI". There were 26 (8.4%) family members who had participated in AMI related training before. There was statistical difference in the training willingness of the patients' family members with different age(P＜ 0.05);there were statistical differences in the training modes among the patients' family members with different age and educational backgrounds (P＜0.05). ConclusionsIt is necessary to develop individualized training program for the acute STEMI patients' family members according to their age and educational backgrounds.

The ability of clinical nursing information is a comprehensive ability of knowledge, technology and attitude expressed in various nursing information activities,which match the capability of nursing practice.Most clinical nursing workers have not been trained by systematic nursing information course,so their ability of nursing information is weak.This research bases on the macro background of China′s current nursing information driven development and national and international clinical nurse′s nursing information competency development status has been reviewed.Through comparative analysis on national and international differences of clinical nurse′s nursing information ability,we put forward the countermeasures of our country clinical nurses nursing information competency development,so as to build up Chinese characteristics of nursing information system and provide a theoretical basis.

Guided by the emphasis on learning process, the educational reform has designed a "trinity" comprehensive evaluation system (quantitative clinical practice, in-class medical record analysis, and staged comprehensive written test) as the formative evaluation of the course. Through this assessment system, students' self-learning potential is stimulated, clinical skills practice is strengthened, and "taking exams to promote learning and taking exams to promote teaching" is realized. In the practice of teaching reform, it has been found that compared with the conventional teaching class, the students in the teaching reform class have higher participation and are more satisfied with the process assessment of the "trinity" comprehensive evaluation system.
