Alzheimer's disease (AD) is a neurodegenerative disease of the central nervous system, and its pathogenesis is very complex.As a large number of microorganisms in the human digestive tract, intestinal flora is the important environmental factor in the process of human health and disease.The brain-gut axis is a bidirectional information regulation system which connects the brain and the gastrointestinal.The intestinal microbes can participate in the brain-gut axis activity, and influence the brain function and some related behaviors under physiological and pathological conditions.Recent studies have shown that intestinal microorganisms are closely related to AD, and they interact with each other through immune, endocrine and vagal pathways to form complex networks.Many reports have shown that probiotics or traditional Chinese medicine can regulate the state of intestinal microflora and improve AD symptoms.Therefore, in order to provide a new research idea and method for the clinical prevention and treatment of AD, it is necessary to further study the interaction between intestinal microbes, traditional Chinese medicine and AD.

OBJECTIVE To evaluate the inhibitory effect of HPSE AS-ODN on the invasiveness of human Hep-2 cell lines. METHODS HPSE AS- ODN which was complementary with initiation codon region of HPSE mRNA was designed and synthesized. After embedded by cation lipofectin, it was transfected into Hep-2 cells of human laryngocarcinoma. The expression of HPSE protein and HPSE mRNA in Hep-2 cell lines were detected by flow cytometry and RT- PCR. Meanwhile Matrigel invasive assay was used to measure the inhibitory effect of HPSE AS-ODN on the invasiveness of human Hep-2 cell lines. RESULTS The HPSE protein and HPSE mRNA expression and invasiveness of human Hep-2 cells treated with AS- ODN of different concentrations were significantly decreased as the AS-ODN concentration increasing. There was a significantly difference between control group and each group of AS-ODN respectively (P

To explore the therapeutic efficacy of extracorporeal shock wave (ESW) for persistent heel pain.A total of 98 patients of persistent heel pain were randomly divided into ESW treatment and control groups (n =49 each).Treatment group had ESW while control group received infrared physical therapy.And their visual analogue scale (VAS) scores were assessed.After one course of treatment, VAS heel pain and function scores were (39.6 ± 6.2) and (25.1 ± 4.6) in ESW group versus (32.3 ± 6.5) and (17.4 ±7.2) in control group.And before treatment, (16.5 ±4.6) and (14.4 ±8.6), (16.1 ±4.7) and (14.6 ± 8.4) respectively.Heel pain significantly decreased with functional improvement (all P ＜ 0.05).After one course, the effective rate was 65％ (32/49) in treatment group.And the improvement rate of 31％ (15/49) was better than control group [27％ (13/49) and 63％ (31/49)] (all P ＜ 0.05).ESW treatment of persistent heel pain was more efficacious than physical therapy and it could be applied clinically.

Objective:To study the diagnosis value of Transcranial Doppler ultrasound for intracranial artery stenosis in patients with cerebral infarction.Methods:A total of 140 patients with acute cerebral infarction,transient ischemic attack and posterior circulation ischemic attack in Department of Neurology,Xinjiang cardiovascular and cerebrovascular disease hospital from October 2014 to October 2016 were selected as research object,CT angiography (CTA) and TCD detection were performed in all patients.Used CTA examination results as the gold standard,the detection results of intracranial artery stenosis in two groups were compared,the diagnostic value of TCD and the diagnostic results of TCD to the degree of bilateral middle cerebral artery (MCA) stenosis were analyzed.Results:CTA diagnosis showed that 140 patients had a total of 105 patients with intracranial artery stenosis,in the anterior and posterior circulation vessel of 1155 intracranial segments,CTA detection showed that 249 vessels were narrow,TCD detection showed that 236 vessels were narrow.Com-pared with CTA,TCD was better in the diagnosis of patients (Kappa value＞0.75).The diagnostic sensitivity and positive predictive value of TCD for MCA were the highest,which were 91.26％ and 93.07％,the consistency was the best (Kappa value =0.917).CTA detection showed that 210 MCA vessels had 103 stenoses,mild stenosis 17,moderate stenosis 41,severe stenosis 45,TCD detection showed that the stenosis was 101,mild stenosis 16,moderate stenosis 40,severe stenosis 45.The Kappa test showed that the diagnostic results of TCD to the degree ofMCA stenosis was better consistency compared with CTA (Kappa value=0.884.Conclusion:TCD has a high diagnostic value for cerebral artery stenosis in patients with cerebral infarction,and it is consistent with the diagnosis of CTA.

Objective:To observe the effects of warming triple needling plus Chinese medication on inflammatory responses and daily functioning ability in patients with knee osteoarthritis(KOA)due to wind-cold-dampness Bi-impediment. Methods:A total of 101 patients with KOA due to wind-cold-dampness Bi-impediment were divided into an acupuncture-medication group and a Chinese medication group using the random number table method.Fifty cases in the Chinese medication group took oral Fang Feng Xi Bi Tang for treatment,and 51 cases in the acupuncture-medication group received additional warming triple needling therapy.The symptom score of traditional Chinese medicine(TCM),inflammatory factor levels,and motor function of the knee joint were compared before and after treatment.The clinical efficacy was also compared between the two groups after treatment. Results:Three cases in the acupuncture-medication group and 2 cases in the Chinese medication group dropped out during the study,and the two groups each had 48 cases being included in statistical analysis ultimately.The total effective rate was 95.8%in the acupuncture-medication group,higher than 79.2%in the Chinese medication group,and the between-group difference was statistically significant(P<0.05).After treatment,the TCM symptom score dropped in both groups(P<0.05)and was lower in the acupuncture-medication group than in the Chinese medication group(P<0.05).The levels of interleukin(IL)-6,tumor necrosis factor(TNF)-α,and IL-1β dropped after the intervention in both groups(P<0.05)and were lower in the acupuncture-medication group than in the Chinese medication group(P<0.05).The scores of knee pain intensity,knee joint stiffness,and diurnal functioning decreased after treatment in the two groups(P<0.05)and were lower in the acupuncture-medication group than in the Chinese medication group(P<0.05). Conclusion:Warming triple needling plus Fang Feng Xi Bi Tang can reduce inflammatory responses,improve daily functioning ability,and enhance the quality of life in patients with KOA due to wind-cold-dampness Bi-impediment.

To investigate the effects of Xuefu Zhuyu Oral Liquid, a compound traditional Chinese herbal medicine for resolving stagnation, on hemorheology in the patients with blood-stasis syndrome due to coronary disease and their relationship with human platelet antigen-3 (HPA-3) polymorphism of membrane glycoprotein IIb (GPIIb).

This study was aimed to optimize the uniform design for effective constituents in water-soluble extractives D, E, F of traditional Chinese medicine (TCM) in Qi-Xue Bing-Zhi Fang (QXBZF) for the further validation of the ratio of different compatibility. A total of 100 SD rats were used in the study. Among them, 90 rats were given high fat feeding for 7 days. Then, stratified randomization was used. The rats were divided into the all-party group; D, E original prescription group; D, E optimized compatible group; D, E between optimized and original group; D, E optimized but anti-compatibility group; all-party group adding F; optimized compatible group adding F; QXBZF with mainly paeoniflorin accounted for 49.12% as component D, total flavonoids accounted for 30.0% as component E, total acids accounted for 32.07% in component F; the positive drug control group (Xue-Zhi-Kang, 0.108 g/kg); and the high fat model group. In addition, a blank control group (with normal diet) was set. Each group was treated with gastric perfusion according to drug compatibility proportion for 14 days. Rats were sacrificed to take blood samples for the detection of serum lipid, platelet aggregation, vasoactive substance, and inflammation level. The results showed that compared with the model group, the QXBZF D, E original prescription group and D, E optimized compatible group had significant decreasing effects on TC (P< 0.05). The lowest level of TC decreased by optimized compatible group was (3.49 ± 0.86) mmol/L. The all-party group, D, E original prescription group and optimized compatible group can inhibit the platelet with maximum aggregation rate effectively(P< 0.05, P< 0.01); while the D, E optimized but anti-compatibility group (with D, E inverse proportion) had no effect on it. All-party group and the D, E original group adding F had significant inhibition on IL-6 and IL-8 (P < 0.05, P < 0.01). The D, E original prescription group, D, E optimized compatible group and D, E between optimized and original group can ascend 6-Keto-PGF1α significantly (P< 0.05). ET-1 was decreased in the D, E optimized compatible group (P< 0.05). Other groups had no obvious effect on vascular active substances. It was concluded that different effects between the QXBZF D, E original prescription group and the D, E optimized compatible group were observed in action segment and strength. When F parts added, inhibitions of inflammation levels were enhanced at certain level.

This experiment was designed to search and identify the active principle as well as the optimal proportion of water-soluble extractives of traditional Chinese medicine (water-soluble extractives) Liqi Huoxue medicinals com-patibility (Qixue Bingzhi Fang-CWQB) in the prevention and treatment of atherosclerosis (As) by optimal uniform design method. The water-soluble extractives of CWQB were divided into 6 sections (A, B, C, D, E, F) through macroporous resin. The effect intensity and step of every component were compared through its effect on blood fat level, platelet aggregation, inflammatory factors, vascular endothelial growth factor (VEGF) and so on among hyper-lipoidemia rat models. The pharmacological experimental results and statistical analysis showed that CWQB water-soluble extractives of component D (mainly is paeoniflorin, accounted for 49.12%), component E (mainly is total flavonoids, accounted for 30.0%) compatibility had better effects on decreasing blood fat and triglyceride (TG). Com-pared with the model group, there was significant difference (P < 0.01). It also had inhibiting effect on endothelin (ET) and maximum platelet aggregation rate (P < 0.01). The component F (mainly is total acids, accounted for 32.7%) had inhibiting effect on serum IL-6 and IL-8 (P< 0.01). It was concluded that different compatibility of wa-ter-soluble extractives of CWQB can be applied to different targets or steps of the body. The active principle extrac-tives include main component of paeoniflorin, flavonoids and total acids. The best proportion is about 1:1:1.
