ObjectiveTo investigate osteopontin (OPN) level in pulmonary tuberculosis and its clinical significance.MethodsThe level of serum OPN was determined in 80 pulmonary tuberculosis patients before anti-tuberculosis treatment[patients group,simple pulmonary tuberculosis with 60 cases (simple pulmonary tuberculosis group),pulmonary tuberculosis combined with tuberculous pleurisy with 20cases (pulmonary tuberculosis combined with tuberculous pleurisy group)],and compared with that of 30healthy persons (healthy control group) and 20 patients having received effective anti-tuberculosis treatment and followed-up for 6 months (followed-up group).At the same time,the clinical significance of OPN was studied by other commonly used clinical indicators of tuberculosis.ResultsThe level of serum OPN in patients group [(843.49 ±569.23) ng/L] was significantly higher than that in healthy control group [(352.50 ± 185.02) ng/L,P ＜0.05].The level of serum OPN after treatment in followed-up group were significantly decreased compared with those before treatment [(494.11 ±352.40) ng/L vs.(1106.60 ± 628.39) ng/L,P＜ 0.05 ] and there was no significant difference compared with those in healthy control group (P ＞ 0.05 ).The level of serum OPN in pulmonary tuberculosis combined with tuberculous pleurisy group [(1179.80 ±606.33) ng/L] was significantly higher than those in simple pulmonary tuberculosis group [(727.53 ±511.66) ng/L,P ＜0.05],and they were both higher than those in healthy control group [ ( 352.50 ± 185.02 ) ng/L,P ＜ 0.05 ].Therefore,for further additional subgroup analysis in simple pulmonary tuberculosis group,the level of serum OPN in patients with cavity[ ( 836.51 ± 549.80) ng/L ] was significantly higher than that without cavity [ (535.52 ± 375.95 ) ng/L,P ＜ 0.05 ],while the levels of serum OPN had no statistical difference between pulmonary lesion involved ＜ 3 leaf patients and ≥ 3 leaf patients,sputum mycobacterium tuberculosis positive patients and negative patients,mycoDot test results positive patients and negative patients,erythrocyte sedimentation rate elevated patients and normal patients,PPD strongly positive patients and non-strongly positive patients (P＞0.05).ConclusionsOPN activity is closely related with pulmonary tuberculosis.OPN can serve as a judge of pulmonary tuberculosis and the clinical indicators of disease outcome.The level of serum OPN and the severity of pulmonary tuberculosis have some correlations.

Objective To investigate the condition of the professional identity and learning burnout in the college students majored in re-habilitation therapy, and discuss the correlation between them. Methods From October to November, 2014, students of grades 2 and 3 ma-jored in rehabilitation therapy were investigated with the professional identity questionnaire and the learning burnout questionnaire. Results A total of 127 questionnaires were sent out, and 119 returned. The score of professional identity was (3.36 ± 0.55), with the factors score of the cognition, emotion, behavior, appropriateness as (3.66±0.77), (3.25±0.60), (3.23±0.71), and (3.36±0.61), respectively. The score of learn-ing burnout was (2.90±0.46), the score of factors of low spirits, improper behavior and low achievement as (2.87±0.70), (3.10±0.60), (2.77± 0.52), respectively. There was negative correlation between score of professional identity and learning burnout (r=-0.271, P<0.01), as well as between some factors of the identity and the learning burnout (P<0.05). Conclusion The professional identity and learning burnout are in the middle level in students majored in rehabilitation therapy, which may interact each other.

Objective To analyze mutations of the STAT3 gene in a patient with hyper-IgE svudrome (HIES) mainly manifesting as multiple cold abscesses.Methods Clinical data were collected and blood samples were obtained from a 17-year-old male patient with HIES and his parents.Genomic DNA was extracted and subjected to PCR for the amplification of the entire coding region and splice sites of the STAT3 gene followed by bidirectional sequencing.Results A heterozygous missense mutation C1427T,which caused a codon change from TCC to TTC and resulted in the substitution of serine by phenylalanine at amino acid residue 476 (p.S476F), was found in exon 16 encoding the DNA-binding domain in the STAT3 gene in the patient, but not in either of his parents.The results of amplified ribosomal DNA restriction analysis were consistent with the findings mentioned above.Conclusion A novel missense mutation S426F was found in the STAT3 gene in the HIES patient with generalized cold abscesses as the prominent clinical manifestation.

Concurrent chemoradiotherapy is the optimal regimen for patients with inoperable locally advanced non-small cell lung cancer (LA-NSCLC).The application of new technologies such as positron emission tomography (PET)/CT and four dimensional CT (4D-CT) enhances the accuracy of radiotherapy and decreases adverse reaction.Induction chemotherapy and consolidation chemotherapy do not show benefit to survival.The targeted therapy and immunotherapy have the potential of improving the outcomes of inoperable LA-NSCLC.

Objective To observe the incidence of orthostatic hypotension and hypertension in the elderly hypertensive inpatients and investigate the effect of antihypertensive medication on the orthostatic blood pressure changes in the elderly hypertensive inpatients.Methods A total of 185 aged hypertensive inpatients was divided into elderly group(n =126,60～79 years old) and very elderly group(n =59,≥80 years old) according to the age.The orthostatic blood pressure was measured in supine position and after standing.Subjects were divided into 3 subgroups:orthostatic hypotension (OH),orthostatic hypertension (OHT),and orthostatic normotension (ONT) groups according to the standing blood pressure levels.Clinical characteristics of each subgroup were evaluated and analyzed according to the antihypertensive medication.Results Among 185 patients,the OH incidence was 31 (16.76％) cases,the OHT incidence was 23 (12.43 ％) cases,and the ONT incidence was 131 (70.81％) cases.There were 16 (12.70％) patients with OH and 10(7.90％) patients with OHT in elderly group,but 15 (25.42％) patients with OH and 13 (22.03％) patients with ONT in very elderly group.The prevalence of OH and OHT in each elderly group was both higher than elderly group (P ＜ 0.05).Antihypertensive medications such as Calcium channel blockers,angiotensin Ⅱ receptor-blockers,Beta-blockers,diuretics,and angiotensin converting enzyme inhibitors were not significantly different among three subgroups.Conclusions OH and OHT were common in the elderly hypertensive inpatients,especially in the very elderly people.The five-class antihypertensive medication that doctors commonly used at present might be not related to the orthostatic hypotension and hypertension.

Objective To evaluate the efficacy and safety of Qijialifei capsule,a kind of Chinese traditional medicine,as adjuvant chemotherapy for retreatment patients with smear positive pulmonary tuberculosis.Methods One hundred and sixty retreatment cases with smear positive pulmonary tuberculosis were divided into observation group (80 cases) and control group (80 cases).All patients received the therapy of 3SHRZE/6HRE.The patients in observation group took Qijialifei capsule.Then comparisons were made between two groups in the sputum tubercle bacillus conversion rate,focus improvement rate,cavity closing rate,the cellular immune function,and clinical symptom improvement.Results In 160 cases,77 cases in observation group and 78 cases in control group completed the treatment.At the end of intensified therapy period and at the end of the whole therapy the sputum tubercle bacillus conversion rate [79.2％ (61/77),92.2％ (71/77)] in observation group were significantly higher than those in control group [64.1％ (50/78),78.2％ (61/78)](P ＜ 0.05).The focus improvement rate,cavity closing rate in observation group [74.0％(57/77),26.0％(20/77)] were significantly higher than those in control group [52.6％ (41/78),11.5％ (9/78)] (P ＜ 0.05).At the end of intensified therapy period,the focus improvement rate,cavity closing rate in observation group [92.2％ (71/77),54.5％ (42/77)] were significandy higher than those in control group [76.9％ (60/78),29.5％ (23/78)] (P ＜ 0.05).By the end of the whole therapy,the number of CD3+,CD4+,CD4+/CD8+ of patients in observation group were significantly higher than those in control group (P ＜ 0.05).The disappearance of clinical symptoms in observation group was shorter than that in control group(P ＜ 0.05).The rate of side effects on Qijialifei capsule was only 1.3％(1/77).Conclusions Qijialifei capsule can improve the cellular immune function of the patients,can effectively alleviate the symptoms and can improve the sputum tubercle bacillus conversion rate,radiographic focus improvement rate and cavity closing rate.It is safe.

Objective To investigate the effects of Glibenclamide on reduction of secondary damage after acute spinal cord injury in rats.Methods Ninety rats were randomly divided into control group (laminectomy alone),spinal cord injury group(injury group),and treatment group(treated with Glibenclamide after spinal cord injury),with 30 rats in each group.The pathological morphology changes of injured spinal cord were observed by HE staining and electron microscope.The expressions of sulfonylurea receptor 1 (SUR1)were detected by immunohistochemical method at 45 min,6 h,24 h,3 d and 7 d after spinal cord injury,and IPP 6.0 software were used for quantitative analysis.The function recoveries of the hind limbs of rats were evaluated by BBB score.The blood sugar level was detected quantitatively.Results HE staining showed that tissue bleeding and microglia proliferation getting severe with time after spinal cord injury.Compared to the injury group,tissue bleeding,microglia proliferation and inflammatory cell invasion was less severe in treatment group.Showed by electron microscope,inflammatory cell invasion,myelin sheath layer structure damage and mitochondrial swelling were significantly reduced after Glibenclamide treatment.Detected by immunohistochemical staining,the expressions of SUR1 at all time points after injury,except for 45 min that there were no SUR1 expressions in all groups,were much weaker in the treatment group than in the injury group.The SUR1 expression reached the peak at 24 h after injury in injury group,and decreased gradually with time.Significant differences were found in the SUR1 expression among three groups by oneway ANOVE.The BBB scores of treatment group were significant higher than that of injury group.The blood sugar slightly decreased in the treatment group,while no significant difference was found among three groups.Conclusion Glibenclamide can significant reduced the secondary damage after acute spinal cord injury.The protection of Glibenclamide after spinal cord injury may relate to its suppression of SUR1.

Objective:To compare the effects of distal movement of canines between elastic traction and canine lace back in the aligning stage of preadjusted appliance. Methods:50 cases with Angle I malocclusion were divided into two groups after first premolar extraction. Patients in both groups were treated by the same kind of preadjusted appliance in the aligning stage. Canine lace back was used in one group and elastic traction in another.Treatment was countinued for 12 weeks.Measurements of the dental models and the cephalograms were conducted before and after treatment.Results:Compared to the canine lace back, the decrease of the width between the cuspids of upper premolars and that between that of lower molars, the increase of the angle of the distally tipped canines and the mesially tipped lower molars and the lingually tipped incisors, the higher speed and larger distance of distal moving canines were achieved more easy with elastic traction. On the contrary, the larger distance of mesial moving molars were attained with canine lace back. The differences of all the measurements above between the two methods were significant(P
