OBJECTIVETo evaluate and analyze the clinical therapeutic effect and characteristics of acupuncture combined with medicine on depression of different syndrome types.

METHODSEighty cases of depression were dividede into liver qi stagnation and spleen deficiency group (group A, 35 cases), deficiency of both heart and spleen group (group B, 21 cases) and yang deficiency of both spleen and kidney group (group C, 24 cases) according to the syndrome differentiation. They were all treated with acupuncture at Baihui (GV 20), Yintang (EX-HN 3), Sishen-cong (EX-HN 1), Neiguan (PC 6) etc. and oral administration of 5-HT selective serotonin reuptake inhibitors (SSRI) tablets. The Hamilton depression scale (HAMD) and self-made syndrome differentiation symptoms evaluation scale were adopted to evaluate the therapeutic effect.

RESULTSAfter treatment of 4 weeks, the total effective rate of 91.4% in group A and of 90.5% in group B, both were superior to that of 87.5% in group C (P < 0.01,P<0. 05). There was a significant difference in comparison of HAMD scores between the group A and group C after treatment of 4 weeks (P < 0.05). The symptom scores of syndrome differentiation in all three groups were obviously decreased after 1 week, 2 weeks and 4 weeks treatment compared with those before treatment (all P < 0.001), the symptom scores of group C had significant differences compared with the group A and group B after treatment of 2 weeks (P < 0.01, P < 0.05). The reducing scores rate of the group A had singificant differences compared with the group B and the group C after treatment of 4 weeks (both P < 0.05).

CONCLUSIONAcupuncture combined with SSRI has better therapeutic effect on depression of liver qi stagnation and spleen deficiency type. The syndrome differentiation symptoms evaluation scale is more exact and sensitive to evaluate the clinical therapeutic effect of TCM treatment.

OBJECTIVETo obtain the monoclonal antibody against hexon protein of human adenovirus.

METHODSBALB/c mice were immunized with purified recombinant hexon protein, and the spleen cells of the mice were isolated and fused with myloma cells. Four hybridoma cell strains were screened by indirect ELISA and cultured, and the sensitivity, specificity and virus neutralizing activity were analyzed with ELISA, Western blotting and neutralizing test.

RESULTSThe mouse ascites produced by these hybridoma cells contained specific monoclonal antibodies against hexon protein of human adenovirus as identified by ELISA and Western blot, and the antibody generated by 4C6 strain showed human adenovirus type 3-neutralizing activity.

CONCLUSIONThe monoclonal antibodies against hexon protein with high specificity have been successfully obtained, and these antibodies can be useful in developing assays for early diagnosis of HAdV3 infection and also in study of therapeutic drugs of the infection.

OBJECTIVETo describe the incidence and mortality rates of esophageal cancer from 1974-2002 in Cixian county of Hebei province. Basic information on comparative geographical, epidemiological, and clinical research was collected.

METHODSIn early 1970s, cancer registry system in Cixian was established, collecting information on all the esophageal cancer cases in Cixian. Data was checked manually, then computerized, coded and analyzed using the software--SPSS 11.5.

RESULTSFrom 1974 to 2002, there were 18 471 esophageal cancer cases in Cixian, with 11 068 males and 7403 females, respectively. The age standardized incidence rate (ASR) for males was 208.77 per 100,000, while 120.47 per 100,000 for females. The trend of incidence rate of esophageal cancer had decreased during the 29 years from 1974 to 2002 (trend chi(2) = 19.94, P < 0.001). From 25 years of age onward, the incidence rates of the lower age groups declined with the increase of age. As for geographic distribution, the incidence rate in mountainous areas and hilly areas showed a significant declining trend in mountainous areas, chi(2) = 195.00, P < 0.001; hilly areas, chi(2) = 46.08, P < 0.001. The esophageal cancer incidence in plain areas remained steady, but had a slight increase in recent years. From 1969 to 2002, there were 18,736 cases died of esophageal cancer with 11 598 males and 7138 females. The ASR for male was 127.17 per 100,000 and 101.57 per 100,000 for female. Compared with the year 1969, the mortality rate of esophageal cancer in 2002 had a 37.96% decline. The proportion of esophageal cancer among malignant tumors in different decades decreased significantly.

CONCLUSIONThe trend of the incidence rate of esophageal cancer had been decreasing for the last 29 years. The incidence rate in mountainous areas and hilly areas showed a declining trend while in the plain areas it remained steady but having slight increase in the recent years. The mortality rate of esophageal cancer had a significant decrease from 1969 to 2002.

OBJECTIVETo evaluate the status of residual alveolar bone in aggressive periodontitis (AgP) nuclear families and to investigate the influence of teeth with root abnormity on residual alveolar bone and the heredity of root abnormity, the premolar cone-root and proportion of crown and root.

METHODSNineteen AgP probands (9 males and 10 females) at average age of 24.5 and 38 parents at average age 51.0 were included. A full set of periapical radiographs of all the subjects were taken. The residual alveolar bone of each tooth was measured by the ratio (shown as percentage) of the distance between apical and the alveolar bone crest to the whole root length. The abnormity of roots was detected on a full set of periapical radiographs. All the roots and crowns of teeth were measured. The relationship between the residual bone and the ratio was studied. The heredity grade of the premolar cone-root, proportion of crown and root, and root abnormity were computed.

RESULTSThe average residual alveolar bone of probands was less than that of their parents.In 11 families, the father's residual alveolar bone was less than that of the mother's. The average residual alveolar bone of the teeth with root abnormity was less than that of normal teeth. The average residual alveolar bone of the teeth with abnormity of roots and the normal teeth were (67.5 ± 22.2)% and (73.1 ± 18.7)% respectively, with statistical significance (P < 0.001). The heredity grade of the premolar cone-root was 40.1%, the heredity grade of proportion of crown and root was 46.8%, the heredity grade of root abnormity was 30.3%.

CONCLUSIONSThe residual alveolar bone of the teeth with root abnormity was less than that of normal teeth in nuclear families. The heritability of the root abnormity, the cone-root and proportion of crown and root in our sample was 0.3-0.5, which means that genetic factors accounted for about one third to half of the efficiency for AgP.
