Objective To observe the efficacy of lowering blood pressures and TCM syndrome on the mild to moderate hypertension via the treatment of auricular syndrome differentiation combined with magnetic point application;To provide reference for clinical treatment of hypertension by non-pharmaceutical therapy. Methods Totally 260 patients with mild to moderate hypertension were randomly divided into control group and treatment group, 130 cases for each. The control group was given Norvasc by conventional oral dosage, and the treatment group was given auricular syndrome differentiation and Yongquan (KI1) magnetic point application additionally. SBP, DBP and TCM syndrome scores of the two groups were observed before and after treatment to evaluate the antihypertensive efficacy and TCM syndrome efficacy. The side effects were also observed. Results After treatment, SBP of the two groups decreased significantly (P<0.05), with no significant difference (P>0.05). DBP of the treatment group decreased significantly (P<0.05), with significant difference compared with the control group (P<0.05). There was no significant difference in antihypertensive efficacy between the two groups (P>0.05). TCM syndrome of treatment group improved significantly compared with the control group (P<0.05). The total effective rate of TCM syndromes in treatment group was better than the control group (P<0.05), without side effects. Conclusion Auricular syndrome differentiation combined with magnetic point application can not only significantly improve the TCM syndrome of patients with mild to moderate hypertension, but also has synergistic hypotensive efficacy and high safety.

Objective To study the expressions of matrix metalloproteinase-1 3 (MMP-1 3)and p73 in gastric adenocarcinoma,and to explore the associations of the expressions of MMP-1 3 and p73 with the clinico-pathological features,and to evaluate their clinical significances for the prognosis of gastric adenocarcinoma metastasis.Methods The immunohistochemistry SP methods was used to evaluate the expressions of MMP-1 3 and p73 in 1 43 cases of gastric adenocarcinoma and 55 normal tissues adjacent to carcinoma,and their associa-tions to the clinicopathologic features were analyzed.Results The expression of MMP-1 3 in gastric adenocarci-noma was significantly higher than that in adjacent tissues of cancer (67.1 3% vs 1 6.35%),with a significant difference (χ2 =41 .1 0,P =0.000).The expression of p73 in gastric adenocarcinoma was significantly higher than that in adjacent tissues of cancer (58.74% vs 1 2.73%),with a significant difference (χ2 =33.86,P =0.000).In the gastric adenocarcinoma,the expression of MMP-1 3 was associated with peripheral lymph node metastasis (χ2 =1 1 .835,P =0.001 ),depth of invasion (χ2 =5.1 77,P =0.032)and TNM stage (χ2 =1 1 .1 07,P =0.001 ),but it was not correlated with the ages of patients (χ2 =0.1 1 3,P =0.853),tumor size (χ2 =0.338,P =0.591 )and tumor differentiation level (χ2 =3.628,P =0.072).In the gastric adenocarci-noma,the expression of p73 was associated with peripheral lymph node metastasis (χ2 =1 1 .440,P =0.001 ), tumor differentiation level (χ2 =5.407,P =0.025)and TNMstage (χ2 =9.497,P =0.003),but it was not correlated with the ages of patients (χ2 =1 .567,P =0.222),tumor size (χ2 =0.841 ,P =0.392)and depth of invasion (χ2 =0.554,P =0.498).The expression of MMP-1 3 was positively correlated with the expression
of p73 in gastric adenocarcinoma group (r =0.684,P =0.000).Conclusion Both MMP-1 3 and p73 may participate in the development of gastric adenocarcinoma,which can be used as an important index for the eval-uation of invasiveness and metastasis in gastric adenocarcinoma.

Objective To explore the gene sequencing and prenatal diagnosis of Glanzmann thrombasthenia (GT). Methods The blood samples were drawn from one case of phenotype GT pediatric patient, patient’s parents, and one normal control. The amniotic lfuid and cord blood from the fetus of patient’s mother were collected. When the fetus was born 2 days, the blood was drawn. The coagulation routine test and platelet aggregation test were performed. The expression of platelet membrane glycoprotein (GP) IIb and GPIIIa were tested by lfow cytometry. Microsatellite technology is used to determine whether fetal cord blood is contaminated with maternal cells. The expressed region and the junctional zone between exon and introns of GPIIb and GPIIIa were ampliifed by PCR technology from blood sample of patient, patient’s parents, and fetus’s cord and 2 days after birth. The PCR products were then subjected to DNA sequencing. Results Adenosine diphosphate (ADP) cannot induce the platelet aggregation in the patient. The max rate of the platelet aggregation in the fetus’s cord blood was half of the normal. However, the max aggregation rate induced by ADP in the blood sample of parents and fetus 2 days after birth were equal to normal. The mean lfuorescence intensity (MnX) of platelet membrane GPIIb and GPIIIa in the patient were 10%and nearly zero of the normal control, respectively, while those in the parents, the fetus’s cord blood and 2 days after birth were more than 90%and 30%to 50%of the normal control. The cast-off cells in amniotic lfuid and the DNA in cord blood analysis by microsatellite technology conifrmed that the amniotic lfuid and cord blood not contaminated by maternal cells. Gene analysis showed the heterozygosis mutation in exon6 A3829→C and exon9 G42186→A of the patient’s GPIIIa led to the amino acid heterozygosis mutation in GPIIIaHis281→Tyr and Cys400→Pro. These two mutations came from the father and the mother separately. However, there was only one heterozygosis mutation in exon9 G42186→A in the cast-off cells in amniotic lfuid, the fetus’s cord and blood 2 days after birth. Conclusion This GT patient have double heterozygosis mutation. The fetus has heterozygosis mutation conifrmed after birth.

OBJECTIVE Epithelial-myoepithelial carcinoma (EMC) is a rare malignant neoplasm of the salivary glands. The aim of the study was to investigate the diagnosis, treatment and prognosis of EMC of the parotid gland.METHODSThe clinical data of 23 cases of EMC of the parotid gland from 1999 to 2013 were analyzed retrospectively. Of all the patients, 13 cases received radical surgery only, 9 cases received postoperative radiotherapy, and one case received postoperative chemotherapy. Kaplan-Meier survival curve was used to analyze the clinical data. RESULTSThe overall survival rate at 5-year was 81.0% and the overall no recurrence survival rate at 5-year was 67.3%. The recurrence rate was 39.1% (9/23). The 5-year no recurrence survival rate of radical surgery group was 55.6%, compared with 80.0% in the combined modality therapy group, there was no significant deference (χ2=2.232, P=0.135).CONCLUSIONThe postoperative recurrence rate of EMC is high. Radical surgery could be the main treatment of EMC, when the surgical margin couldn't be achieved, adjuvant radiotherapy or chemotherapy might be helpful.
