Objective To study the effect of gastrin, motilin of chronic atrophic gastritis model in rats by acupuncturing at back-shu points. Methods 60 SD rats were randomly divided into blank control group, model control group, omeprazole group, back-shu points group, with 15 rats in each group, and to establish the model of chronic atrophic gastritis by irregular diet that given rats odd and even days. The blank control group, model control group were fed with normal saline, 2ml/time, 1 time/day. The omeprazole group was given oral gavage(Omeprazole 0.44 mg/kg, Clarithromycin 6.92 mg/kg, Metronidazole 7.6 mg/kg), 1 time/day. Back-shu points group received acupuncture at “Geshu”“Ganshu”“Pishu”“Weishu”“Shenshu”, retaining 15 min, 1 time/day. After 30 days, the content of ELSIA was used to detect the serum gastrin, motilin. Results ①GAS of model control group(54.25±5.70)pg/ml was significantly decreased compared with blank control group(66.63± 5.99)pg/ml, the difference was statistically significant (P<0.05). Compared with the model control group, GAS content of omeprazole group(62.70±8.55)pg/ml and back-shu Points group(66.27±3.79)pg/ml were higher, showed significant differences(P<0.05). ②MOT of model control group(223.60±17.83)pg/ml was significantly increased compared with the blank control group(188.45 ± 8.90)pg/ml, the difference was statistically significant(P<0.05). MOT of omeprazole group(200.16 ± 4.38)pg/ml and back-shu Points group(190.11±10.04)pg/ml were lower than those in the model control group, there was statistically significant difference(P<0.05). Conclusion Acupuncturing at back-shu acupoints can increase the content of GAS, reduce content of MOT, regulate gastrointestinal hormone in rats of chronic atrophic gastritis model.

Parkinson disease (PD) is a common neurodegenerative disease,of which clinical symptoms give priority to movement disorders,accompanied by a series of non-motor symptoms,such as pain.Studies suggest that 40％ to 85％ of PD patients combined with pain,of more nature is related to muscleskeletal and dystonia.PD combined with pain severely reduces the quality of life of patients.However,it is still lack of uniform clinical evaluation and effective treatment.This paper makes a brief overview about the status and research progress of the evaluation and treatment of PD combined with pain.

Asthma is the most common chronic respiratory disease in children. Currently,inhaled corti-costeroids is the most effective drug for asthma,however,there are some adverse effect by long-time using. Ac-cording to recent literature,long-time treatment with inhaled corticosteroids may inhibit height growth. But this suppression only occurs within early stage of asthma treatment, and have no effect or slight effect on adult height. The adverse effects of inhaled corticosteroids for height are also related to its iypes,dose and usage.

Objective: To explore change of heart rate turbulence (HRT) in patients with coronary artery disease (CAD) and its predictive value. Methods: A total of 58 CAD patients were regard as CAD group. The 50 normal persons with negative CAG were regard as normal control group. All subjects received 24h dynamic ECG, CAG and echocardiography examination. Left ventricular ejection fraction (LVEF) and HRT indexes were compared between two groups. Results: Compared with normal control group, there was significant rise in turbulence onset [TO, (-1.34±1.09)% vs. (2.32±0.60)%] and significant reduction in turbulence slope [TS, (11.14±2.27) ms/RR vs. (3.44±0.60)ms/RR] in CAD group, P<0.01 both; in CAD group, along with coronary artery lesion aggravated (single-, double-, multi-vessel coronary disease), there was significant rise in TO [(1.35±0.52)% vs. (2.56±0.83)% vs. (3.01±1.62)%] and significant reduction in TS [(6.49±1.79) ms/RR vs. (3.33±1.02) ms/RR vs. (1.66±0.30) ms/RR], the difference was significant in two-two comparison among all groups, P<0.05 or <0.01; compared with CAD without cardiac event group, there was significant rise in TO [(1.68±0.61)% vs. (2.24±0.24)%], and significant reduction in TS [(5.87±1.22) ms/RR vs. (1.65±0.23) ms/RR] and LVEF[(66.18±2.64)% vs. (56.36±3.34)%] in CAD with cardiac event group, P<0.01 all. Conclusion: Weakened HRT phenomenon exists in CAD patients. HRT can be treated as an index evaluating severity of CAD patients’ condition and an effective predicting index for recurrent cardiac events in CAD patients.
