OBJECTIVE: To investigate the effects and mechanism of Buyang Huanwu Decoction and the like on primary cultured neonate hippocampal neurons induced by oxygen deprivation and reoxygenation. METHODS: The primary cultured hippocampal neurons cell model was established, oxygen sugar deprivation/reoxygenation (OGD/R) model was established in vitro. CCK-8 was used to determine the concentration of Buyang Huanwu Decoction and the like drug-containing serum to protect hippocampal neurons cell. The experimental groups were divided into control group, model group, Buyang Huanwu Decoction drug-containing serum group(10%), Naoxintong Capsule drug-containing serum group(10%), Yangyin Tongnao Granules drug-containing serum group(10%), Buyang Huanwu Decoction drug-containing serum+TAK-242 group(10%,1 μmol•L-1), Naoxintong Capsule drug-containing serum+TAK-242 group(10%,1 μmol•L-1), Yangyin Tongnao Granules drug-containing serum+TAK-242 group(10%,1 μmol•L-1). The morphology of hippocampal neuron was observed under inverted microscope. The expression of tumor necrosis factor-α(TNF-α) and interleukin 1(IL-1β) in the cell supernatant was detected by ELISA kit. The neuronal cell apoptosis was observed by Hoechst 33358 staining fluorescence microscope and the expression of TLR4/NF-κB signaling pathway proteins was detected by Western blot. RESULTS: The results showed that hgher purity neuronal cells can be obtained by primary culture. Compared with model group, Buyang Huanwu Decoction and the like all can reduce the release of TNF-α and IL-1β in hippocampal neurons, significantly reduced the number of apoptosis. At the same time, the three traditional Chinese medicine compounds all can inhibit the expression of TLR4 and NF-κB protein in TLR4/NF-κB signaling pathway, and protect the inflammatory response of oxygenated sugar deprivation and reoxygenated hippocampal neurons. The addition of TLR4-specific inhibitor TAK-242 blocked the conduction of this signaling pathway and reduced the protective effect of Buyang Huanwu Decoction and the like. CONCLUSION: Buyang Huanwu Decoction and the like have protective effects on OGD/R-induced inflammatory response in hippocampal neurons, its mechanism may be related to TLR4/NF-κB signaling pathway, and the anti-inflammatory protective effect of Naoxintong Capsule is relatively obvious.

Objective To research the differential expression of trace phosphorylated proteins in human gastric adenocarcinoma epithelial (AGS) cells infected by Helicobacter pylori. Methods H. pylori 26695 strain infected AGS cells 4 h and AGS cells was cultivated for 4 h as a comparison. The proteins of AGS and comparison AGS cells were extracted. Their phosphorylated proteins were enriched by metal ion af-finity adsorption enrichment techniques. After desalinated and purified the phosphorylated proteins samples were separated by 2-dimensional polyacrylamide gel electrophoresis (2-DE) technique. Computer assisted image analysis was used to analyze the differential proteomic expression. The significantly differentially ex-pressed proteins were unambiguously assigned identities by matrix-assisted laser desorption/ionization-time of flight mass spectrometry (MALDI-TOF/TOF). Results Fifteen kinds of proteins were down-regulated, 4 kinds of new proteins were observed, 1 kind of proteins were up-regulated, 1 kind of proteins unexpression. The 21 proteins that were significantly differentially expressed , including cellular calcium ion homeostasis, transcription, interpretation, protein folding and transport, ribosomal assembly, centrosome replication, chromosome stability, cellular structure, cellular proliferation and apoptosis. Conclusion H. priori can cause a wide range change to human gastric adenocarcinoma epithelial cell protein pheshorylation. This change character has great significance to further comprehensive understanding of the pathogenesis of H. pylori.

Objective: To observe the clinical efficacy of tendon-regulating and bone-setting manipulation combined with endurance resistance exercises in treating female with chronic neck pain, and explore the mechanism. Methods: A total of 57 female patients with chronic neck pain who met the inclusion criteria were randomly divided into a manipulation group (29 cases) and a medium-frequency electrotherapy group (28 cases). Patients in both groups received the same endurance exercise therapy, while those in the manipulation group received additional tendon-regulating and bone-setting manipulation, and those in the medium-frequency electrotherapy group received additional medium-frequency electrotherapy. Both groups were treated for 5 weeks. Before and after treatment, the neck function of patients was evaluated by visual analog scale (VAS), Analgesy-Meter, Northwick Park questionnaire (NPQ), root mean square (RMS) and median frequency (MF) of surface electromyography of sternocleidomastoid muscle and posterior cervical extensor muscle, and the patients were followed up at a month after treatment. Results: All patients completed the treatment and were followed up. Compared with the same group before treatment, the VAS scores of both groups decreased, the tenderness values increased, the RMS and MF values increased, and the NPQ scores decreased after treatment (all P<0.05). The improvement of manipulation group was more notable than that of medium-frequency electrotherapy group (all P<0.05). At one-month follow-up, the VAS and NPQ scores of the manipulation group were lower than those before and after treatment, and the VAS and NPQ scores of the medium-frequency electrotherapy group were only lower than those before treatment; the two scores of the manipulation group were lower than those of the medium-frequency electrotherapy group (both P<0.05). Conclusion: Tendon-regulating and bone-setting manipulation combined with endurance resistance exercises can relieve neck pain and cervical dysfunction in female patients with chronic neck pain. The efficacy of this method is more durable and better than that of medium-frequency electrotherapy combined with endurance exercises.

Objective: To evaluate the clinical efficacy of sinew-regulating bone-setting manipulations plus exercise therapy in treating chronic non-specific low back pain (CNLBP). Methods: A total of 65 CNLBP patients were divided into two groups by the random number table method. Thirty-three cases in the treatment group were intervened by sinew-regulating bone-setting manipulations plus exercise therapy; 32 cases in the control group were intervened by medium-frequency electrotherapy plus exercise therapy. Before and after treatment, visual analog scale (VAS), dynamic and static muscle endurance of low back, median frequency (MF) of surface electromyography (sEMG) and Oswestry disability index (ODI) were used to evaluate the low back function. The therapeutic efficacy was estimated after treatment. Results: The two groups each had 2 dropouts during the study. The total effective rate was 90.3％ in the treatment group versus 66.7％ in the control group, and the between-group difference was statistically significant (P<0.05). After treatment, the VAS score, dynamic and static muscle endurance of low back, MF of sEMG and ODI score all changed significantly in both groups (all P<0.05); all the items in the treatment group were significantly different from those in the control group (all P<0.05). Conclusion: Sinew-regulating bone-setting manipulations plus exercise therapy can effectively release pain in CNLBP patients, increase muscle endurance of the low back and improve the quality of life, and its therapeutic efficacy is more significant than that of medium-frequency electrotherapy plus exercise therapy.

Objective To evaluate the effects of chronic disease management on carotid atherosclerosis. Methods From May 2016 to October 2016, 500 subjects with carotid atherosclerosis diagnosed by ultrasound at the Physical examination center of the First Hospital of Jilin University were enrolled. The participants were aged 55?65(60.7±3.5) years. They were divided into the control group (n=250) and intervention group (n=250) using a random number table; a total of 20patients, 13 in the control group and 7 in the intervention group, were lost to follow-up at the end of the study. The control group only received anti-atherosclerosis treatment, while the intervention group underwent additional chronic disease management, and a 1-year follow-up study was conducted. The health of all the subjects was assessed at the beginning of the study and after the study, based on the health file. The chi-square test, two independent sample t-tests, and rank sum test were used to evaluate the effect of chronic disease management on carotid atherosclerosis. Results After 1 year of intervention, the proportion of patients with an unhealthy lifestyle (smoking, excessive drinking, high-salt diet intake, high-fat diet intake, lack of exercise, and overweight/obesity) decreased in the intervention group(10.3%, 13.1%, 7.8%, 8.6%, 6.2%, 28.0%, vs. 28.8%, 35.0%, 21.0%, 22.6%, 13.2%, 39.5%; χ2=26.49, 33.01, 17.09, 18.03, 6.80, 7.21; P<0.05), while the drug compliance increased(44.4% vs. 35.4%, χ2=4.15, P<0.05), and the total cholesterol (TC), triglyceride (TG), low density lipoproteincholesterol (LDL-C), fasting plasma glucose (FPG), uric acid (UA) and blood pressure (BP) compliance rate also increased (91.8%, 73.3%, 83.1%, 83.1%, 52.3%, 76.5%, 74.1%, 60.5%, vs. 67.5%,72.8%,28.0%,58.8%, respectively; χ2=26.86, 8.92, 15.97, 7.49, 29.81, 17.39, respectively; P<0.05); all indicators, except the drug compliance control rate, were better than those in the control group. After 1 year of intervention, the degree of carotid atherosclerosis in the intervention group was significantly reduced compared to that in the control group. Conclusions Chronic disease management could effectively interfere the control risk factors of atherosclerosis, such as smoking, drinking, obesity or overweight, BP, levels of FPG, blood lipids, and UA, improve drug compliance, delay the progression of atherosclerosis and provide a basis for the construction of the atherosclerosis management model.
