Objective To investigate the influence of renal function on serum BNP in the diagnosis of CRF with heart failure by observing the relationship between eGFR and BNP in serum and comparing cut-off values of BNP in different eGFR levels. Methods The elderly participants were enrolled in the study, including 52 patients with heart failure, and 29 patients without heart failure and 30 healthy controls. Serum BNP level was measured by ELISA.Results The level of serum BNP increased significantly in subjects with heart failure compared with those with renal dysfunction for no-heart failure patients (P ＜ 0.05) and healthy controls. BNP level was significantly higher in CRF no-heart failure patients than in control subjects. eGFR showed negative correlation with BNP in ESRD no-heart failure patients (γ= -0. 581, P ＜ 0.01). There was no correlation between eGFR and ESRD with heart failure patients (γ= - 0.081, P ＞ 0.05). The AUC of BNP in patients (eGFR 30 ～ 60 ml) was 0. 951, when cut-off value was 1 500 ng/L,the sensitivity and specificity of BNP were 96.4% and 86. 7% respectively. The AUC of BNP in patients(eGFR ＜30 ml)was 0. 860, when cut-off value was 1 850 ng/L,the sensitivity and specificity of B NP were 66.7% and 92.9%respectively. Conclusions Heart failure was major factor result in higher levels of BNP in chronic renal failure with heart failure patients. BNP could be used as a diagnostic marker for CRF with heart failure patients.

Conclusion The blood glucose control among T2DM patients is mainly affected by age, body mass index, disease course, smoking, drinking, medication adherence and comorbidities.

Objective To localize the tibial attachment of the posterior cruciate ligament (PCL) on the magnetic resonance imaging (MRI) and provide parameters for clinical PCL reconstruction.Methods We retrospectively analyzed 524 patients with intact tibial PCL attachment who had undergone knee MRI from January 2010 to January 2016.They were 286 men and 238 women with an average age of 35 years (from 20 to 50 years).The size and positions of the tibial PCL attachment were measured on the sagittal and coronal MRI slices.The differences were analyzed between different genders.Results On the sagittal slices,the mean distance from the central tibial PCL attachment to the posterior edge of the tibial plateau was 17.9 ± 3.0 mm and the mean anteroposterior diameter of the tibial PCL attachment was 9.7 ± 2.4 mm,with those for males significantly larger than for females (P ＜ 0.05).The above mean values when expressed as a percentage of the posterior tibial slop were 79.9％ ±4.5％ and 43.7％ ± 9.6％,respectively,showing no significant differences between males and females (P ＞ 0.05).On the coronal slices,the distances from the central tibial PCL attachment to the medial and lateral edges of the tibial plateau were 33.5 ± 3.1 mm and 37.4 ±4.1 mm,respectively,and the mediolateral diameter of the tibial PCL attachment was 12.0 ± 1.6 mm,with those for males significantly larger than for females (P ＜ 0.05).The above mean values when expressed as a percentage of the mediolateral diameter of the tibial PCL attachment were 47.4％ ± 3.2％,52.7％ ±3.1％ and 16.9％ ± 1.7％,respectively,showing no significant differences between males and females (P ＞ 0.05).Conclusions On knee MRI images,the distance from the central tibial PCL attachment to the posterior edge of the tibial plateau is about 17.9 mm,the anteroposterior diameter of the tibial PCL attachment around 9.7 mm,and the mediolateral diameter of the tibial PCL attachment roughly 12.0 mm.These measurements for males are larger than for females.

Objective By observing the effect of deeply needling Lianquan (CV23) plus acupuncture at the ten nape points on the deglutition function in post-stroke pseudobulbar palsy, to objectively evaluate the efficacy of deeply needling Lianquanplus acupuncture at the ten nape points in treating post-stroke pseudobulbar palsy.Method A total of 141 patients diagnosed with post-stroke pseudobulbar palsy were divided into a treatment group (71 cases) and a control group (70 cases) by following asimple-randomized design (random number table). The treatment group was intervened by deeply needling Lianquan plus acupuncture at the ten nape points, while the control group was intervened by conventional acupuncture. A month later, the general therapeutic efficacy, Kubota's water drinking test, Toshima Ichiro's swallowing assessment, and Standardized Swallowing Assessment (SSA) were evaluated, and the therapeutic efficacies of the two groups were compared.Result The general therapeutic efficacy, waterdrinking test result, Toshima Ichiro's swallowing assessment, and SSA score were significantly improved in both groups after the treatment (P<0.05). After the treatment, the general therapeutic efficacy, water drinking test result, Toshima Ichiro's swallowing assessment, and SSA score in the treatment group were significantly different from those in the control group (P<0.05), and the treatmentwas superior to the control group. The total effective rate was 91.5% in the treatment group, versus 70.0% in the control group, and the between-group difference was statistically significant (P<0.05).Conclusion Deeply needling Lianquan plus acupunctureat the ten nape points is effective in treating post-stroke pseudobulbar palsy, superior to the conventional needling method.

OBJECTIVE: This article summarizes the matters warranting consideration in adult cochlear implants before and after operation with different deafness causes and investigates the impact of etiological variables that affect hearing and speech ability rehabilitation after cochlear implantation. METHOD: We retrospectively reviewed the preoperative data of 30 adults who have received cochlear implantation, switch on, and periodical post operative mapping. 'Nijmegen Cochlear Implant Questionnaire' was used for every patient during follow-up and test their hearing thresholds at one year after switched-on. The average score of every patient in the six aspects of questionnaire, along with the average hearing threshold, has been gathered. RESULT: The average hearing threshold of every patient is lower than 35 dBHL. The average score of 28 patients is more than or equal to 75 in the basic sound perception, advanced sound perception as well as self-esteem. The average score of 26 patients is more than or equal to 75 in capacity for action. Besides, as for sociability and speech ability, the average score of 22 patients is more than or equal to 75. CONCLUSION Auditory perception can be greatly improved regardless of deafness causes, on the premise that appropriate candidate is selected. The primary disease should be brought under control before and after the operation. The influence of various causes to the language ability rehabilitation largely depends on the development of the language center at deafness onset. Self-esteem and social identity can be significantly enhanced after cochlear implantation in adult patients, particularly those with acquired deafness.

AIM: To investigate the CPU86017 and its enantiomers inhibit abnormal gene expression of calcineurin and NFκB in rat cardiomyopathy induced by L-thyroxin and compare the effect of CPU86017 (racemate) with its 4 enantiomers: (7S, 13R), (7S, 13S), (7R,13S), and (7R,13R)-CPU86017 in this model. METHODS: The animals were randomly divided into 7 groups. The rat hypertrophied model was produced by treatment with L-thyroxin 0.2 mg·kg-1·d-1, sc for 10 d and treated with CPU86017 or its enantiomers 4 mg·kg-1·d-1, sc from d 6 to d 10. The changes in left ventricular (LV) weight index, redox system, and the NO and iNOS activity in the myocardium were investigated. The expression of mRNA of calcineurin、NF-κB in the left ventricle was measured. RESULTS: There were significant cardiac hypertrophy and oxidative stress in rats treated by L-thyroxin. The expression of calcineurin, NFκB mRNA were upregulated (P<0.05, compared with that of control). After treatment with CPU86017 (racemate and enantiomers), LV remodeling and the redox system were improved. CPU86017 and (7S,13R)-CPU86017 showed a better improvement on LV remodeling and the redox than the other isomers and restored the normal expression of calcineurin, NF-κB (P<0.05, P<0.01), respectively. CONCLUSION: It suggested that an up-regulation of calcineurin and NFκB possibly related to the altered intracellular calcium handling system plays a role in the progression of L-thyroxin induced cardiomyopathy and CPU-86017 and its 7S,13R-CPU86017 enantiomer effectively inhibit the abnormal expression of calcineurin and NFκB genes, the NOS enzyme and oxidant stress in the cardiomyopathy.
