OBJECTIVETo verify the clinical efficacy on post-stroke dysphagia treated with acupuncture at Lianquan (CV 23).

METHODSOne hundred and eighty patients were randomized into an acupuncture A group, an acupuncture B group and a rehabilitation group, 60 cases in each one. On the basis of the conventional medication, in the acupuncture A group, acupuncture was applied at Lianquan (CV 23); in the acupuncture B group, acupuncture was applied at Hegu (LI 4) and Neiguan (PC 6) and in the rehabilitation group, the swallowing rehabilitation training was adopted. The treatment was given once a day, 5 times a week, and the 4 weeks of treatment was required in all of the groups. The national institute of health stroke scale (NIHSS) and TV X-ray fluoroscope swallowing scale (VFSS) were used to evaluate neurologic deficit and swallowing function before and after treatment in the patients of each group. The morbidity of pneumonia and clinical efficacy were compared among the groups.

RESULTSThe scores of NIHSS and VFSS were improved apparently after treatment in the patients of the three groups (all P < 0.05) and the results in the acupuncture A group were superior to those in the other two groups (all P < 0.05). The morbidity of pneumonia in the acupuncture A group was lower than that in the acupuncture B group and the rehabilitation group [3.3% (2/60) vs 6.7% (4/60), 8.3% (5/60), both P < 0.05]. The effective rate in the acupuncture A group was better than that in either of the other two groups [95.0% (57/60) vs 81.7% (49/ 60), 75.0% (45/60), both P < 0.05].

CONCLUSIONOn the basis of the conventional medication, acupuncture at Lianquan (CV 23) effectively improves the swallowing function, relieves neurological deficit and reduces the morbidity of pneumonia in the patients of post-stroke dysphagia.

Objective: To prepare Lingyi Formula multicomponent microemulsion and evaluate its anti-lung cancer activity. Methods: Lingyi Formula multicomponent microemulsion was prepared by aqueous titration method using polysaccharides solution of Ganoderma lucidum and Coix lachryma-jobi var. ma-yuen as aqueous phase and coix seed oil as oil phase, loading ganoderma triterpenes. The average particle size, Zeta potential, and stability were detected. The results of antitumor efficacy including tumor inhibitory rate, body weight change, immune organ index, and concentration of TNF-α and IL-6 were investigated. Besides, pathological section of tumor tissue and TUNEL labeling were conducted subsequently. Results: The prepared microemulsion displayed spherical surface with mean droplet size of (69.92 ± 8.43) nm, polydispersity (PDI) of 0.060 ± 0.008, and Zeta potential of (-11.30 ± 1.34) mV. Tumor inhibitory rate of microemulsion (57.25%) was significantly higher than that of suspension (45.89%), immune tissue index as well as the concentration of TNF-α and IL-6 were increased significantly. TUNEL labeling and pathological section of tumor tissue showed that the antitumor activity of microemulsion was significantly effective compared with that of suspensions. Conclusion: Lingyi Formula multicomponent microemulsion has a good anti-lung cancer activity.

Objective To evaluate the cancer risk of benzene and formaldehyde in different indoor air environments in Guiyang city.Methods From 2004 to 2005,benzene and formaldehyde monitoring was conducted in bedrooms,living rooms, kitchens,offices,classrooms and outdoor environments in winter,spring and autumn,and human health risk assessment was done. Results The mean benzene and formaldehyde concentration in different environments were lower than the China indoor air quality standard except for formaldehyde concentration in offices.The benzene cancer risks of male and female adults were 1.63?10~4 and 1.40?10~(-4)respectively.The formaldehyde cancer risks of male and female adults were 6.05?10~(-4)and 5.23?10~(-4) respectively.The human formaldehyde cancer risk was higher than benzene cancer risk,and the risk for male was higher than that for female.Benzene and formaldehyde cancer risks of different population in different indoor environments were above 1.00?10~(-6), the acceptable level of human cancer risk.Conclusion The benzene and formaldehyde concentrations in different environment in Guiyang city has the high cancer risks to human health.

Objective To analyze the peripartum complications,frequency of neonatal abnormalities and the associated factors in patients with primary Sj?grenˊs syndrome (SS). Methods The chart of 39 patients with primary SS who were admitted to the hospital for delivery were retrospectively reviewed. The clinical data, obstetrical outcome and the frequency of neonatal abnormalities as well as the possible associated factors were analyzed. Results There were 76 pregnancies and 41 deliveries among these 39 patients. Two patients (5%) had pregnancy-related hypertension, 1 (3%) had gestational diabetes and 1 (3%) had eclampsia. Twenty-eight(72%) patients had at least one episode of complication. In which, 27(68%) were induced abortion, 2 (5%) were premature birth, 6 (21%) were amniotic fluid volume abnormalities, 2 (5%) were post-partum bleeding, 5 (13%) were premature rupture of membrane, 6 (21%) were intra-uterine distress and 3 (8%) had intra-uterine growth retardation. Fetal abnormality was detected in 7(18%) patients, in which 3 fetus (8%) died before delivery, 2 fetus (5%) were small than gestational age and 2 (5%) had fetal deformity. Compared to the reports in the literature, the rate of abortion and fetal death was higher, but the rate of growth retardation , induced abortion was lower. Conclusion The frequency of peri-partum complication and fetal abnormality is increased in patients with primary SS. Pregnancies in patients with primary SS should beclosely monitored by rheumatologists.

By interpreting the connotation of physical factors and its significance in the syndrome differentiation of traditional Chinese medicine (TCM), ideas and methods of the combination of physique differentiation and syndrome differentiation of coronary heart disease (CHD) were proposed. The physique classification research was promoted and standardized. Research methods of physique differentiation were improved. The connotation of relationship between constitution and syndrome was mined. The essence of different syndromes was explored on different syn-dromes of CHD. The physique differentiation, disease differentiation and syndrome differentiation were integrated with the viscera-state theory and syndrome factor differentiation theory. The difference of proteomics technology was used as the means to reveal the pathogenesis of same disease with different syndrome of different CHD constitution. Multidisciplinary crossover study was developed on CHD with constitution theory of TCM and clinical actively, so as to make it better to direct the clinical scientific research practice of CHD.
