OBJECTIVETo compare the difference in the clinical efficacy on post-stroke insomnia between the low-frequency electric stimulation at the acupoints and the conventional western medication.

METHODSOne hundred and twenty patients of post-stroke insomnia were randomized into a low-frequency electric stimulation group, a medication group and a placebo group, 40 cases in each one. In the low-frequency electric stimulation group, the low-frequency electric-pulsing apparatus was used at Dazhui (GV 14) and Shenshu (BL 23), once a day; the treatment of 15 days made one session and 2 sessions were required. In the medication group, estazolam was taken orally, 1 mg each time. In the placebo group, starch capsules were taken orally, 1 capsule each time. All the drugs were taken before sleep every night, continuously for 15 days as one session, and 2 sessions were required. PSQI changes and clinical efficacy were observed before and after treatment in each group.

RESULTSPitlsburgh sleep quality index (PSQI) score was reduced in every group after treatment (all P < 0.01). In the low-frequency electric stimulation group and medication group, the score was reduced much more significantly as compared with the placebo group (both P < 0.01). In the placebo group, 1 case was rejected. The total effective rates were 95.0% (38/40), 92.5% (37/40) and 17.9% (7/39) in the low-frequency electric stimulation group, medication group and placebo group separately. The efficacy in the low-frequency electric stimulation group and medication group was better apparently than that in the placebo group (both P < 0.01).

CONCLUSIONThe low-frequency electric stimulation at the acupoints effectively and safely treats post-stroke insomnia and the efficacy of it is similar to that of estazolam.

Objective To study the relationship between gene polymorphism of apolipoprotein E (apolipoproteinE,ApoE)of peripheral blood and Mycoplasma pneumoniae infection in children.Methods Collected 236 cases serum of inpatient and outpatient screening in children with Mycoplasma pneumoniae infection and healthy children between March 2011 and March 2014 in the First Affiliated Hospital of Xi’an Medical University and Xi’an Children’s Hospital,at the age of 3~8 years old,divided into two groups:110 cases of control group and 126 cases of Mycoplasma pneumoniae infection in chil-dren.Used multiple allele-specific PCR (multi-AS PCR)to detect gene polymorphism of ApoE in each group.Results ApoE gene was polymorphic and 6 genotypes:3 homozygous (ε2/2,ε3/3,ε4/4)and 3 heterozygote (ε3/2,ε3/4,ε4/2).Theε3/2 had four bands,ε3/3,ε3/4 and 4/2 had three bands,ε2/2 andε4/4 had two bands.ε3/3 of ApoE genotype distribution in two groups was the most common,control group was 66.7%,infection group was 46.4%.Allele frequencies ofε3 and genotype frequencies ofε3/3 inMycoplasmapneumoniae infection of children were lower than those in control group (P<0.05).But allele frequencies ofε4 and genotype frequency ofε4/4 in Mycoplasma pneumoniae infection of children were increased, which were compared with those in control group (P<0.05).Conclusion There were an association between ApoE gene polymorphism and the incidence of Mycoplasma pneumoniae infection in children.Allelesε3 seems to be a protective factor and allelesε4 may contribute to the development of Mycoplasma pneumoniae infection of children.

ObjectiveTo investigate theeffectof expression of excision repair cross complementing 1(ERCC1) on adjuvant chemotherapy and prognnsis in advanced gastric cancer.MethodsIn this study 88 advanced gastric cancer cases were divided into initial neoadjuvant chemotherapy group (45 patients) and upfront surgical group (43 cases).In neoadjuvant chemotherapy group two courses neoadjuvant chemotherapy with XELOX were given before an interval standard radical gastrectomy.Postoperatively another four cycles of chemotherapy with XELOX were given; In upfront surgical group standard radical gastrectomy was done followed by 6 cycles of postoperative chemotherapy with XELOX;Patients in the two groups were followed up for 3 years.ResultsERCC1positive expression were 49％ and 44％ in neoadjuvant group and surgical patients; Response rate in neoadjuvant chemotherapy group was 49％.Patients with ERCClnegative expression were more sensitive to chemotherapy (P ＜0.05 ); 3-year recurrence-free survival rate in patients with ERCC1negative expression was 64％,which was significantly higher than 30％ in patients with positive expression,the difference was statistically significant (P ＜ 0.05 ) ;3-year recurrence-free survival rate in initial surgical group patients with ERCCl-negative expression was 79％,significantly higher than in patients with positive expression (38％),the difference was statistically significant (P ＜0.05) ; Cox regression analysis revealed that ERCC1expression is closely related to 3-year disease-free survival ( P ＜ 0.05 ). ConclusionsERCC1expression in patients with advanced gastric cancer is related to chemosensitivity and prognosis,it can forecast the prognosis and chemotherapy sensitivity.

OBJECTIVETo observe the clinical efficacy difference in treatment of functional dyspepsia (FD) between syndrome differentiation based acupuncture and ordinary acupuncture.

METHODSSeventy FD patients were assigned to a syndrome differentiation based acupuncture group (Group A) and an ordinary acupuncture group (Group B) by Excel Software randomization. Zhongwan (RN12 ), Tianshu (ST25), and Zusanli (ST36) were needled as main points for patients in Group A. Meanwhile, different combined acupoints were needled according to syndrome differentiation. Only the same main points were needled for patients in Group B. All patients were needled once per day, 30 min each time, 6 days as one treatment cycle, 2 treatment cycles in total. Fasting serum levels of gastrin (GAS) and motilin (MTL) were determined before treatment and after 2 treatment cycles. 36-item Short-form Heath Survey (SF-36) and Nepean Dyspepsia Index [NDI, including Nepean Dyspepsia Symptom Index (NDSI) and Nepean Dyspepsia Life Quality Index (NDLQI)] were assessed before treatment, after 2 treatment cycles, and one month after treatment.

RESULTSCompared with before treatment in the same group, serum levels of GAS and MLT increased in the two groups after 2 treatment cycles (P <0. 05), but changes were more obvious in Group A (P <0. 05). Compared with before treatment in the same group, SF-36 and NDLQI score increased, and NDSI score decreased in the two groups after 2 treatment cycles and 1 month after treatment (all P <0. 05). Compared with Group B, SF-36 and NDLQI score increased in Group A after 2 treatment cycles and 1 month after treatment (P <0. 05, P <0. 01). But NDSI score at 1 month after treatment was lower in Group A than in Group B (P <0.01).

CONCLUSIONSyndrome differentiation based acupuncture could evidently improve dyspeptic symptoms of FD patients, and significantly improve their quality of life with remarkable curative effect.
