Alzheimer′s disease (AD) is a degenerative neurodegenerative disease of the central nervous system. The disease is concealed. Patients often experienced several years or even more than ten years of course evolution from the beginning of pathological changes to clinical symptoms. Once entering the stage of dementia, there is no ideal drug to reverse the disease. In order to improve the efficiency of early diagnosis, the research on early biomarkers of the disease has become a hot topic in recent years. In addition to the Aβ and tau, microRNAs have been discovered as potential biomarkers of AD.

We proposed a multi-resolution-wavelet-transform based method to extract brainstem auditory evoked potential (BAEP) from the background noise and then to identify its characteristics correctly. Firstly we discussed the mother wavelet and wavelet transform algorithm and proved that bi-orthogonal wavelet bior5. 5 and stationary discrete wavelet transform (SWT) were more suitable for BAEP signals. The correlation analysis of D6 scale wavelet coefficients between single trails and the ensemble average of all trails showed that the trails with good correlation (> 0. 4) had higher signal-to-noise ratio, so that we could get a clear BAEP from a few trails by an average and wavelet filter method. Finally, we used this method to select desirable trails, extracted BAEP from every 10 trails and calculated the I-V inter-waves' latency. The results showed that this strategy of trail selection was efficient. This method can not only achieve better de-noising effect, but also greatly reduce the stimulation time needed as well.

Objective The study was designed to investigate the effect of atomization inhalation of Qingjin-Huatandecoction on prevention of elderly patients’ postoperative pulmonary complications after thoracotomy.MethodsA total of 60 elderly patients with thoracotomy were randomized into 2 groups. Both groups of patients were treated with oxygen uptake, anti-infection, antispasmodic, analgesic, and nutritional support. Based on the conventional treatment, the control group was added with atomization inhalation of mucosolvan and dexamethasone, while the treatment group with atomization inhalation ofQingjin-Huatan decoction. The volume of phlegm, serum CRP, TNF-α level and absolute neutrophil count (ANC), arterial blood gasanalysis, and records of the pulmonary complications were meausred.Results The pH value at Day 3 (7.39 ± 0.06vs. 7.36 ± 0.05,t=2.120), the PaO2at Day 3 (86.51 ± 3.96 mmHgvs. 84.07 ± 3.51 mmHg,t=2.520) and Day 5 (92.27 ± 2.94 mmHgvs. 90.40 ± 3.08 mmHg,t=2.400) of treatment group were significantly higher than those of the control group; the PaCO2at Day 3 (44.57 ± 2.53 mmHgvs. 46.39 ± 3.35 mmHg,t=2.390) and  Day 5 (40.77 ± 2.48 mmHgvs. 42.42 ± 3.33 mmHg,t=2.130) of treatment group were significantly lower than those of the control group. The serum CRP at Day 3(8.26 ± 2.38 mg/Lvs. 9.76 ± 2.37 mg/L,t=2.440) and Day 5 (6.94 ± 1.76 mg/Lvs. 8.15 ± 2.38 mg/L,t=2.250), the ANC at Day 3 (8.54 ± 1.85)×109/Lvs. (9.58 ± 1.94)×109/L, t=2.140) and Day 5 (6.54 ± 1.85)×109/Lvs. (7.58 ± 1.95)×109/L,t=2.160), the serum TNF-a at Day 5 (7.54 ± 1.38 mg/Lvs. 8.43 ± 1.36 mg/L,t=2.540) of treatment group were significantly lower than those of the control group. The sputum volume at Day 3 (50.74 ± 18.46 ml/dvs. 59.92 ± 15.25 ml/d,t=2.099) and Day 5 (39.64 ± 18.21 ml/dvs. 48.99 ± 13.55 ml/d,t=2.256) of treatment group was lower than that of the control group. At Day 5, the pneumonia (3.33%vs. 20.00%,t=4.043) and the atelectasis (6.67%vs. 26.77%,t=4.320) of treatment group were significantly lower than those of the control group(P<0.05).ConclusionAtomization inhalation ofQingjin-Huatandecoction can improve pulmonary function of postoperative pulmonary complications of elderly patients after thoracotomy, take control of inflammation and the occurrence of postoperative pulmonary complications.

There is a trackphenomenon in the development of hypertension and pediatric hypertension has an important predictive value for adult hypertension. However pediatric hypertension is not typical and normal blood pressure is associated with age,sex and height. The blood pressure level,clinical presentation and complication rates of secondary pediatric hypertension are higher than primary pediatric hypertension. So secondary pediatric hypertension could get timely treatment compared to primary pediatric hypertension. This paper focus on the clinical presentation and diagnosis criterion of pediatric hypertension and provide a reference for the pediatrician.

The core problem of current rural health services is a governance problem, that is, how the basic rural health resources can be used more effectively. Based on the study of history and reality, this paper suggests that in the existing “government-market” framework, the village is the third perspective worthy of consideration. Inside the village community, the trust, network and cooperation between people which were based on the traditional rural acquaintances society capital and the institutional resources in the organizations at the primary level will be able to in-crease the degree of organization, thereby reducing the transaction costs between the government or the market and rural residents. The village power will be able to better take advantage of government and market mechanisms, and thus solve the problem of rural health resource utilization more effectively.

Objective To explore the curative effect of ursodeoxycholic acid in treatment of intrahepatic cholestasis of pregnancy (ICP) and the effect on total bile acid (TBA) in post partum fetal umbilical venous blood .Methods 30 patients with intrahepatic cholestasis of pregnancy who were admitted into the Hospital Affiliated to Sichuan Medical University during January 2014 to December 2014 were selected as the research objects and randomly divided into observation group and control group ,15 cases in each group.The observation group were given ursodeoxycholic acid tablets while control group were injected with ademetionine butanedisulfonate .The curative effect of two kinds of drugs in treatment of intrahepatic cholestasis of pregnancy was observed and the effect on total bile acid in post partum fetal umbilical venous blood was analyzed .ResuIts After treatment , the TBA and ALT of observation group were significantly lower than those pre-treatment and those of control group (P<0.05).There were no significant differences of TBIL and ALP between two groups and within groups.TBA and TBIL in post partum fetal umbilical venous blood of observation group were significantly lower than those of control group (P<0.05).There was no significant difference of ALT level between two groups .There were two cases of abnormal perinatal outcomes in observation group while seven cases in control group (χ2 =3.97, P<0.05).ConcIusion Ursodeoxycholic acid could effectively reduce the total bile acid levels in maternal and fetal umbilical vein blood, reduce the mortality rate of the fetal and improve the perinatal outcomes , with high security.

Objective To study the reconstruction and secretory function of the grafts after adrenal transplantation using fetal rats as donors.Methods Thirty adult SD rats randomly received sham operation(group A),excision of bilateral adrenals(groups B,C,D and E),and additionally adrenal transplantation in groups C,D and E using fetal rats aged 16,18 and 20 days respectively as donors.Results The weight of group A got down to the lowest at the 3rd week,and restored to the preoperation level at the 4th week after sham operation.The weight of group B gradually rose up within 4 weeks.The weight of groups C and D rose up in the first 2 weeks,then down.The weight of group E rose slowly within the first 3 weeks,then down.The serum level of corticosterone decreased sharply in group B after operation,while that of groups C,D and E went down obviously in the first 2 weeks,then up,but that in group C was significantly lower than that in groups D and E.Microscopically,we found the capsule of allografts thicken and underneath many proliferative cells and well-constructed glomerular and fascicular zone 4 weeks after operation.Conclusion After transplantation,the fetal adrenal could survive and reconstruct well,and its secretory function gets better gradually.The graft from the elder donor is better than that from the younger in reconstruction and secretory function,but shows no obvious difference in immunological rejection.
