Objective To detect the expressions of circulating microRNAs (miRNAs) of peripheral whole blood in Alzheimer's disease (AD) and investigate the potential roles of the miRNAs as diagnostic bi omarkers for Alzheimer's disease.Methods Peripheral blood samples were obtained from 110 AD patients and 150 age-and gender-matched normal controls.The concentrations of seven candidate miRNAs,including miR-9,miR-29a,miR-29b,miR-101,miR-181c,miR-137and miR-126,were measured with a real-time quantitative reverse transcriptase polymerase chain reaction (qRT-PCR) method.The data of two groups were collected and analyzed by SPSS 19.0 software.Results It was found that miR-29a (P=1.12×10-5) and miR-101 (P=6.24× 10-7) were markedly down-regulated in peripheral blood of AD patients compared with normal controls.In addition,logistic regression analysis revealed peripheral whole blood miR-29a/101 combination could be a potential biomarker of AD with better specificity (82％) and sensitivity (75％).Conclusions miR-29a/101 combination in peripheral whole blood may serve as a useful noninvasive diagnostic biomarker for AD.

Objective To discuss the effects of sevoflurane on perioperative hemodynamics and serum cardiac troponin I(cTnI) in patients undergoing abdominal surgery,and offer the reference for selecting anesthetic in clinic.Methods Forty patients with ASA Ⅱ—Ⅲ,undergoing radical gastrectomy were randomly allocated into sevoflurane group(group S) and propofol group(group P),with each 20 patients.Systemic blood pressure(SBP),diastolic blood pressure(DBP),heart reat(HR) and saturation of oxygen(SPO2) were monitored as routine.The concerntration of cTnI was examined at pre-anesthesia(T1),post-induction(T2),beginning of operation(T3),end of operation(T4),the first day post-operation(T5) and the third day post-operation(T6) with radioimmunoassay.Results SBP,DBP and HR in group P at post-induction were significantly lower than those in group S(P

Objective:The research was performed to understand the expression of CD80,CD86 and its ligand CD28 on peripheral lymphocytes in patients suffered from idiopathic thrombocytopenic purpura(ITP).Methods:The expression of co-stimulatory molecules(CD80,CD86 and its ligand CD28)on peripheral lymphocytes from 34 ITP patient samples and 34 normal samples was detected by immunofluorescence and flow cytometry.Results:The expression of CD80 and CD86 on peripheral lymphocytes from ITP patients(4.21?2.27%,7.19?5.16%) was higher than that of the normal samples as control(2.34?0.87%,4.08?1.96%,p

Objective:To explore the structure of maternal verbal scaffolding features and develop a questionnaire on Mother's language scaffolding characteristics, so as to provide a quantitative, convenient and economical self-assessment tool for describing maternal verbal scaffolding features.Methods:On the basis of qualitative research and literature research, a questionnaire survey was conducted among 704 mothers of preschool children. After item analysis and exploratory factor analysis, a formal questionnaire was formed. Two weeks later, 106 mothers were retested to collect test-retest reliability data. Preschool children's expressive vocabulary checklist was used as external criterion.Data were analyzed by SPSS 18.0 and Amos 21.0.Results:(1)The formal questionnaire includes 28 items with two factors-detailed support factor and control rejection factor, the internal consistency coefficients of the two factors were 0.849 and 0.811, the project load was from 0 .482 to 0 .701, and the variance contribution rate was 40.36%.(2) AMOS 21.0 was used for confirmatory factor analysis, indicating that the two-factor structure met the requirements of psychometrics.( χ 2/ df=1.96, RMSEA=0.05, NFI=0.86, CFI=0.90, IFI=0.89). (3)The results of two-factor text-retest reliability were 0.840 and 0.871 as well as the results of split-half reliability was 0.801.The internal consistency reliability was 0.740.The external validity analysis showed that the mother's education level was positively correlated with factor Ⅰ( r=0.288, P=0.000), but not with factor Ⅱ( r=-0.091, P=0.052). There was significant difference in factorⅠbetween mothers with expressive vocabulary development delay children (52.22±10.56) and non delayed children (57.71±7.51) ( t=-5.07, P=0.000). There also was a significant difference in factor Ⅱ between mothers with expressive vocabulary development delay children (37.12±10.09) and non delayed children (31.53±8.59) ( t=4.61, P=0.000). (4)There was no significant difference in the characteristics of language scaffolding between boys(factorⅠ(58.08±8.14), factorⅡ(32.86±9.51)) and girls' mothers(factorⅠ(56.93±8.20), factorⅡ(31.42±8.48)). Analysis of the sample groups showed that age did not affect the verbal scaffolding features of preschool children's mothers( F1=1.633, P1=0.181; F2=0.758, P2=0.518). Conclusion:There are two factors in the questionnaire of the verbal scaffolding features questionnaire, which meet the criteria of psychometrics.The questionnaire of the verbal scaffolding features questionnaire is suitable for evaluating the characteristics of language scaffolding of mothers of preschool children aged 3-6.

Objective To investigate the superiority of direct multi-slice spiral CT venography in inferior vena cava. Methods Twenty-eight patients performed MSCT venography in inferior vena cava, including 2 cases with both indirect and direct venography, 10 cases with indirect venography, 20 cases with direct venography through unilateral or bilateral lower extremity venous injection. The image quality and enhancement degree of the inferior vena cava were compared in double-blind method. Results Of 10 cases with indirect venography of inferior vena cava, 1 case was failed due to mild enhancement in inferior vena cava. Image quality was good in 2 cases, poor in 7 cases, no excellent case. Of 20 cases with direct venography of inferior vena cava, the enhancement degree was scored 1, 2 degree in 16, 4 cases respectively and no case was scored 3 degree, the image quality was excellent, good in 16, 4 cases and no case was bad. The success rate was 100%. Conclusion The image quality of direct MSCT venography in inferior vena cava is better than that of indirect method.

Objective To investigate the clinical features and disease-causing mutations of familial hypomagnesaemia with hypercalciuria and nephrocalcinosis.Methods In February 2016,a 24 year old female patient with left kidney stone and nephrocalcinosis in bilateral kidneys was admitted to our hospital.One month prior to this admission,she had been treated by PCNL to remove the most part of left kidney stone in otherhospital.Mter admission,She was found hypomagnesaemia (serum magnesium 0.65 mmol/ L) and hypercalciuria (24h urine calcium 364.0 mg) but with normal renal function (serum creatinine 101.5μmol/L).And the remained part of left kidney stone was removed by flexible ureteroscope.As she was considered probably with an autosomal recessive FHHNC,an analysis of CLDN16 and CLDN19 gene mutations was performed using her and her parents'peripheral white blood cells.Results Mutation analysis revealed this patient had two heterozygous mutations in the CLDN16.One is an one-base deletion mutation in the 123th codon in exon 2:368delA.The other is a missense mutation in the 139th codon in exon 2:416C →T which resulted in an amino acid change Ala139Val.Her parents respectively had one of each heterozygous mutation.In the six months follow-up,an oral administration with hvdrochlorothiazide,potassium citrate,and calcium magesium supplements significantly reduced her hypomagnesaemia (serum magnesiun 1.0 mmol/L) and hypercalciuria (24-h urine calcium 156.0 mg),and no stone recurrence and aggravation of nephrocalcinosis and renal dysfunction occurred.Conclusions We diagnosed a patient with FHHNC who had a novel compound heterozygous mutation of CLDN16.This rare disease should be suspected if there are three constant clinical features of hypomagnesaemia,hypercalciuria and nephrocalcinosis,and verified with CLDN16 and CLDN19 gene test.Currently the option for treatment of FHHNC is symptomatic treatment until severe deterioration of renal function.The hydrochlorothiazide,potassium citrate,and calcium magesium supplements may have considerable effects on hypomagnesaemia and hypercalciuria.

Objective:To explore the application effect of traditional Chinese medicine comprehensive nursing on elderly patients with coronary heart disease(qi stagnation and blood stasis type) constipation.Methods:A total of 126 elderly patients with coronary heart disease (qi stagnation and blood stasis type) constipation were divided into the control group and the experimental group by random digits table method, 63 cases each; the control group received routine nursing, and the experimental group was given traditional Chinese medicine comprehensive nursing; comparing the two groups of patients defecation, mental state, recurrence rate, and nursing satisfaction.Results:There was no significant difference in defecation frequency, each defecation time, defecation smoothness score, fecal trait score, fall inflated score, and self-Rating Anxiety Scale (SAS) score( P >0.05). After one month of nursing, defecation frequency, each defecation time, defecation smoothness score, fecal trait score, fall inflated score, and SAS score were (4.09±0.86) times/week, (5.12±1.24) min/time, (2.57±0.39) points, (1.53±0.31) points, (0.97±0.21) points, (49.27±4.15)points in the experimental group, (3.12±0.61) times/week, (6.87±1.52) min/time, (2.59±0.36) points, (2.02±0.44) points, (1.29±0.27) points, (54.42±6.01) points in the control group, the differences were significant ( t values were -6.638-7.081, all P<0.05). Within 1 month after nursing, the recurrence rate of constipation in the experimental group (14.3%, 9/63) was lower than that in the control group (74.6%, 47/63) , and the satisfaction rate of the experimental group (98.4%, 62/63) was higher than that in the control group (69.8%, 44/63) , the differences were significant(× 2 values were 46.414, 19.257, P<0.05). Conclusions:Traditional Chinese medicine comprehensive care for elderly patients with coronary heart disease (qi stagnation and blood stasis type) constipation can significantly improve their defecation and psychological state, and can reduce the recurrence rate and improve the patient's satisfaction with nursing, which deserves further clinical application and research.

Objective To explore the effect of posterior debridement, grafting and internal fixation for treatment of non-specific lumbar intervertebral infection. Methods Clinical data of 20 patients with non-specific lumbar intervertebral infection treated in General Hospital of Ningxia Medical University from October 2013 to June 2013 were retrospectively analyzed. There were 15 males and 5 females with an average age of 41 years (range, 36-51 years). All patients suffered from single lumbar inter-vertebral infection, including 3 cases at L2/3,4 at L3/4,10 at L4/5 and 3 at L5/S1. All 20 cases underwent one-stage posterior debride-ment, autogenous bone grafting and internal fixation, tissue samples in focus were collected for bacterial culture and pathological examination. The disease controlling statues were evaluated based on laboratory results of ESR and CRP. Imaging examinations were taken to evaluate the fusion of vertebral body. Clinical effects were evaluated using the visual analog scale (VAS) and the Jap-anese Orthopaedic Association scores (JOA) score of lumbar fumction. Results All patients underwent the surgery successfully. The surgery duration time was 90-160 min, average 125 min, and the blood loss was 200-700 ml, average 360 ml. Cerebrospinal fluid leakage occurred in one case. Postoperatively, all patients experienced significant reliefof back pain, improving in the func-tion of movement, and no fever. The lower back VAS score: average (5.35 ± 1.15) points before operation , average (2.76 ± 0.34) points one week after operation, and an average score of (0.85±0.65) points by the last follow-up time. JOA lumbar function score:all patients were effective after operation, the improvement rate was excellent in 65%(13cases), good in 25%(5 cases), and pass-able in 10%(2cases). Comparing with preoperation, the excellent and good rate was 90%. All patients ESR and CRP returned to normal levels at the last follow-up. Ordinary bacterial culture was positive in 8 cases and negative in 12 cases. The pathogens iden-tified were staphylococcus aureus (6 cases), Escherichia coli (2 cases) and staphylococcus epidermidis (2cases). All incisions achieved primary healing. All patients were followed up from 6-18 months (average,12 months), and the symptom of pain relieved significantly. No recurrent infection had happened. A solid bony fusion was found in all patients at 6-14 months (average, 8.5 months) after the surgery. Conclusion Posterior debridement, grafting and internal fixation are effective treatments for non-spe-cific lumbar intervertebral infection, can reduce the time of staying in hospital, this operation is safe and reliable.

Clinical studies have confirmed that cryoablation is a safe and effective treatment for lung cancer. Cryoablation has been clinically used in the treatment of various types of lung cancer,and has achieved good therapeutic effects. Some of the complications of cryoablation can be alleviated after symptomatic treat-ment. However,cryoablation still needs further research and exploration in clinical applications.
