35 cases of rotavirus enteritis occurring in months from September to December of 1980 and 1981 were reported. Typical rotavirus particles were found in 35 out of 54 stool specimens examined with electron microscope. The positive rate of EM was 64.8%.The age of the patients was ranged from 4 months to 2 years; 65.7% of them were 6 to 12 months old. There were 22 males and 13 females.The clinical manifestations consisted of diarrhoea, fever(80%), vomiting (62.8%), mild-to-moderate dehydration(85.7%), and metabolic acidosis(37.17%), upper respiratory infection symptoms(4g.57%). In 40% of the cases, the white cells in the feces were increased in number. Secondary bacterial infection occurred in 4 cases( 11%),which was higher than that of other reports.The main route of transmission was fecal-oral; the presence of respiratory symptoms in some patients suggested the possibility of air-borne spreading.The incidence of this disease was low in the new borns. It is most likely that they arc protected with the passive immunity obtained through the placenta. Furthermore, the structural and physiological characteristics of the gastro-intestinal tract of the neonatus are also contributive to reduce the disease in them.

Objective · To study the expression of microRNA-143 (miR-143) in human colon cancer and adjacent normal tissues, and to explore its effect on the function of colon cancer cells and downstream target genes. Methods · Lentiviral expression vector of miR-143 was designed and used to stably transfect colon cancer cell lines HCT116 and RKO. Real-time PCR was used to detect the expression of miR-143 in colon cancer, adjacent normal tissues, HCT116 cells and RKO cells infected with lentivirus. The apoptosis ratio of HCT116 cells and RKO cells was detected by Annexin V-APC single staining and flow cytometry. The migration ability of HCT116 cells and RKO cells was detected by Transwell method. The expression of FOSL2 protein was detected by Western blotting assay. Results · The expression of miR-143 in colon cancer tissue was significantly lower than that in adjacent mucosal tissue (0.339±0.454 vs 1.003±0.003) (U=16.000, Z=-4.231, P=0.000). By up-regulation of miR-143, apoptosis rates were significantly higher in HCT116 and RKO cells than those in the negative controls (P=0.000). The count of migrating HCT116 cells in up-regulated group was significantly lower than that in the negative control group (P=0.000). The count of migrating RKO cells in down-regulated group was significantly higher than that in the negative control (P=0.003). By down-regulation of miR-143, the expression of FOSL2 protein was increased. Conclusion · The expression of miR-143 was significantly decreased in colon cancer tissues. Up-regulation of miR-143 can promote the apoptosis rate in both cell lines, and inhibit the migration ability of HCT116 cells. Down-regulation of miR-143 could promote the migration ability of RKO cells. By inhibiting miR-143, the expression of FOSL2 protein in colonic cancer cells would be increased.

Objective Discuss the treatment mechanism of Xiaofeng Xuanqiao Decoction on guinea pig with al ergic rhinitis. [Methods]Sixty guinea pigs were randomized into 6 groups: normal control group, al ergic rhinitis(AR) group, high-dosage, equivalent-dosage, low-dosage Xiaofeng Xuanqiao decoction group, and loratadine group. AR guinea pig model was successful y established by ovalbumin(OVA) chal enge method. Xiaofeng Xuanqiao decoction and loratadine were applied to intervene AR guinea pig. The serum levels of IgE and IL-4, IFN-γ, histamine were determined by ELISA methods. [Results]The expression levels of IgE and IL-4, histamine significantly increased,meanwhile the level of IFN-γsignificantly lower compared with the normal group(P<0.01). Compared with that in AR model group, the serum level of IgE and IL-4, histamine in high-dosage Xiaofeng Xuanqiao decoction group significantly decreased,but the level of IFN-γ increased(P<0.01); the levels of IgE and IL-4, histamine decreased in other medication groups, meanwhile the level of IFN-γ increased compared with the model group(P<0.05).[Conclusion]Xiaofeng Xuanqiao can promote the produce of IFN-γ, inhibit the formation of IL-4, promote the secretion of Th1/Th2 cytokines to restore balance, to relieve eosinophil activation, reduce the synthet-ic of IgE, reduce the release of histamine, in many ways to prevent al ergic rhinitis inflammation, to achieve therapeutic effect.

Objective To observe the clinical efficacy of therapy of nourishing kidney and liver for the treatment of hypomenorrhea with the syndrome of kidney deficiency and liver stagnation. Methods Fifty-one hypomenorrhea patients with the syndrome of kidney deficiency and liver stagnation were randomized into treatment group(N =25) and control group (N = 26). The treatment group was treated with oral use of Yangyin Shugan Capsules (mainly composed of Radix Bupleuri, Radix Paeoniae Alba, Radix Rehmanniae Preparata, and Fructus Ligustri Lucidi). The control group was given placebo capsules orally. After treatment for 8 weeks , the overall efficiency and therapeutic effect on menstruation of the two groups were evaluated according the changes of traditional Chinese medicine(TCM) symptom scores. Results(1) The total effective rate of the treatment group was 84.0％, and that of the control group was 15.4％, the difference being significant between the two groups (P < 0.01). (2) The effective rate on the menstrual volume and menstrual color and texture of the treatment group was 64.0％, 68.0％, and that of the control group was 7.7％, 15.4％ respectively, the difference being significant(P < 0.01). However, the difference of effect on improving menstrual period was insignificant between the two groups (P > 0.05). Conclusion Therapy of nourishing kidney and liver is effective for the treatment of hypomenorrhea with the syndrome of kidney deficiency and liver stagnation, and has obvious effect on improving menstrual volume and TCM symptoms.
