Aim To investigate the effect of Radices Paeoniae Alba extract on estrogen receptor (3 ( ERp ) and serotonin transporter(SERT) in the hippocampus of rat model of premenstrual syndrome( PMS) liver-qi inverse syndrome. Methods The rats were randomly divided into the normal group, the model group, the Radices Paeoniae Alba extract group, the fluoxetine group and the ER(3 agonist group by the vaginal smear microscopy and the open field score. The model group rats were prepared by electrical stimulation to prepare PMS liver-qi inverse syndrome. After five days of administration, the hippocampal tissues of each group were separated. ERp and SERT mRNA and protein expression in each group were determined by RT-PCR and immunofluorescence histochemical method. Results During the estrous reception period, there was no significant difference in the behavior score of the open- field test and the expression of ERp and SERT mRNA and protein in the hippocampus of each group. Estrous non-reception period; compared with normal rats, the total distance of open field test in model rats increased significantly. The expression of ER(3 mRNA in hippocampus significantly decreased and SERT mRNA significantly increased. In model group, the pyramidal cells in hippocampal CA1 and CA3 brain areas of rats were irregularly arranged, and the number of ERp positive cells and protein expression decreased. The number of SERT positive cells and protein expression were significantly up-regulated. After the Radices Paeoniae Alba extract was given, the above indexes were significantly improved, and no significant difference was found between them and fluoxetine group and ER agitator group. Conclusions Radices Paeoniae Alba extract may adjust the PMS card of diseases with inverse nega-tive emotions possibly by improving the hippocampus ER|3 and SERT mRNA and protein expression.

Along with the spread of human immunodeficiency virus 1 (HIV-1) infection in the world and the emergence of drug-resistant viral strains, it is urgent to seek the novel potent therapies. Chemokine receptor 5 (CCR5) is one of the main coreceptors involved in the entry of HIV-1 into target cells. Nowadays, a number of CCR5 antagonists have been developed and some of them have progressed to clinical trials or been approved. Research progress has also been made in the CCR5-targeted gene therapy. This review summarizes the recent research progress on the CCR5-targeted drug and gene therapy.

OBJECTIVEOmenn syndrome is a rare autosomal recessive hereditary severe combined immunodeficiency. The purpose of this study was to understand clinical characteristics and genetic mutation type of Omenn syndrome and to improve the recognition of Omenn syndrome among pediatric clinicians.

METHODOne suspected case of severe combined immunodeficiency was found to have pneumonia repeatedly, intractable diarrhea, poor antibiotic treatment effect, lymphadenopathy, hepatosplenomegaly and erythroderma. The patient was diagnosed as having Omenn syndrome by RT-PCR, and the expression of RAG1/RAG2 and gene analysis of RAG1/RAG2 were performed.

RESULTThe classification of lymphocyte was CD3(+) cells (35.3%), CD19(+) cells (0.4%), CD16(+) cells (57.6%). After stimulation with phytohemagglutinin (PHA), lymphocyte proliferation of the child was extremely low. Genetic studies showed RAG1 homozygous deletion mutation (2302 del T). He had detectable activated T-lymphocytes with low circulating B-lymphocytes and no evidence of maternal T-cell engrafment as indicated by the short tandem repeat (STR) analysis.

CONCLUSIONOmenn syndrome is a severe combined immunodeficiency disease caused by mutations in the RAG1/RAG2 gene. The disease has been reported rarely in China. The clinical manifestations of the disease is early postnatal repeated infections and erythroderma. Mutation analysis of RAG1/RAG2 gene may help to confirm the diagnosis and may be useful in early immune reconstitution and genetic counseling.

Methods Case report sheet for senile hypertension was formed, and then the general data and TCM syndrome information of 495 cases of senile hypertension were recorded. The frequency of syndrome information of the enrolled cases was analyzed, and then the syndrome types were classified by cluster analysis. Results The symptoms with high frequency in senile hypertension patients were dizziness ( 75.9%) , insomnia ( 33.1%) , chest distress ( 29.9%) , poor appetite ( 23.2%) , headache (22.4%), slippery pulse (54.9%), greasy fur (51.7%), stringy pulse (49.7%), and white fur (47.8%) . The main syndrome patterns of 495 cases of senile hypertension were upward hyperactivity of liver yang (23.8%), Qi deficiency and phlegm turbidity (21%), kidney qi deficiency (19.8%), phlegm blended with blood stasis (18.4%), and phlegm heat (17.0%) . Conclusion Senile hypertension patients are dominated with the syndrome types of upward hyperactivity of liver yang, Qi deficiency and kidney deficiency, and are usually complicated with phlegm turbidity, phlegm heat and blood stasis. The complicated syndromes of phlegm turbidity and blood stasis are commonly-seen. The results of cluster analysis are expected to supply evidence for the syndrome differentiation of senile hypertension.

OBJECTIVETo explore the therapeutic efficacy of patients with ulcerative colitis (UC) treated by retention enema and per-colonoscopic spraying of Zhikang Compound Liquid (ZKCL).

METHODSEighty-six patients with UC were divided into two groups. The 52 patients in the treated group were treated for 4 courses of retention enema, the drug for enema used in the 1st course was ZKCL-A (consisted of normal saline, Zhikang capsule, gentamycin and dexamethasone) and smecta, in the 2nd course ZKCL-A alone, in the 3rd and 4th course, ZKCL-B (with the same contents of ZKCL-A but without dexamethasone), the enema was carried out once a day in the evening, 15 days as one course. Besides, local spraying of ZKCL-A and smecta were given once by colonoscopy before the 1st and 3rd course. The 34 patients in the control group were treated by salicylazosulfapyridine orally.

RESULTSIn the treated group, 32 patients got complete remitted, 15 were treated effectively, 5 ineffectively, the total effective rate being 90.38% while the corresponding number in the control group were 8, 14, 12, and 64.71%, respectively. Significant difference was seen when compared with the therapeutic effects of the two groups. CONCLUSION Good efficacy was got in treating patients with UC by retention enema and per-colonoscopic spraying with ZKCL.
