In order to investigate the effects of cis-UCA on cell -mediated immunity, we established a murine model of DTH response to DNP6OVA which is indicated by the increasing in the ear thickness of the mouse after resensitization, compared with those of the mouse injected with 200 g cis - UCA and trans -UCA intraperitoneally (i. p. ). The average of the increasing in ear thickness of each group was 9. 1 1. 13 10-2 mm (n=8, the number of ears) for the group administrated with cis-UCA; 17. 45 0. 88 10 - 2 mm (n= 8) for the group administrated with trans-UCA ; 16. 43 + 1. 83 10 - 2 mm(n= 7) for control group. It is suggested that there are immunosuppression of DTH response to DNP6OVA in mouse administrated with ets-UCA and no effecs of trans-UCA on this response.

CXCL12 and its receptor CXCR4 can express in breast cancer,and are regulated by several factors in the genesis and development of breast cancer. Lots of researches have proved that CXCL12 and CXCR4 can be used as new independent prognostic makers of breast cancer.Treatment targeted for CXCR4 can be seen as a new kind of combination therapy,which may provides patients a more ideal treatment.

Objective To investigate the present situation of use of the antipsychotic in schizophrenic inpatients,To find out factors of using the antipsychotic.Methods The prescriptions of schizophrenic inpatients was investigated in cross-sectional survey.Results The 47 remedy in 465 schizophrenic inpatients were investigated.The remedy of use of single antipsychotic had 175 patients(37.6%),the remedy of use of combined 2 kinds of antipsychotic had 262 patients(56.3%),the remedy of use of combination 3 kinds of drugs had 28 patients(6.0%),combined more than two drugs therapy was very common;Using rate and constituting rate of clozapine in prescription were No.1,non-classical antipsychotics was playing a leading role in the antipsychotic;Inpatients with public health services used non-classical antipsychotics more than inpatients of non-public health services.Conclusion Non-classical antipsychotics is replacing classical antipsychotics in curing schizophrenic.Paying way of patient influences the antipsychotic choice.

Objective:To investigate the influence of concanavalin A(Con A) pretreatment on the development of the fulminant murine hepatitis induced by an adequate dose of Con A.Methods:An adequate dose of Con A(15 ?g/g.body.wt) was injected intravenously into C57BL/6 mice to provoke severe liver damage,an extensively-used murine hepatitis model.A low dose of Con A(3 ?g/g.body.wt) was administrated intravenously 12 h before injection with an adequate dose of Con A.Liver injury was evaluated by serum transaminase assay and H&E staining.Hepatic lymphocytes were analyzed by flow cytometry and the absolute amount of lymphocytes per liver was calculated.Results:Pretreatment with a low dose of Con A significantly inhibited Con A-induced liver injury.Both the percentage and the absolute number of liver CD3~+T cells in Con A-pretreated mice were lower than those of PBS-pretreated mice.The activation of liver CD3~+T cells in Con A-pretreated mice was also prominently inhibited.Conclusion:Con A pretreatment exerted the negative effect on the development of Con A-induced hepatitis,which may be result from the decreased recruitment of T cells into the liver.The underlying mechanisms are under investigation.

A reversed phase high performance liquid chromatographic ( RP-HPLC ) method was proposed by using C18 column tandem crown ether chiral column for simultaneous separation of three kinds of aromatic amino acid enantiomers. The chromatographic conditions, including mobile phase proportion, pH, column temperature and flow rate, were optimized. The experimental results showed that the three aromatic amino acid enantiomers could be successfully separated under the optimal conditions such as perchloric acid solution-acetonitrile ( 86:14, V/V, pH = 2 ) as mobile phase, column temperature of 20℃ and flow rate of 0. 4 mL/min. The separation under four HPLC column connection modes was further investigated. The results revealed that different kinds of amino acids could be separated on C18 column, but not for amino acid enantiomers; amino acid enantiomers could be separated on crown ether chiral column, but the chromatographic peaks of each amino acid enantiomers overlapped seriously; baseline separation of three amino acid enantiomers could be obtained under the connection of two columns, but the separation under different column connection sequence almost had no difference except the peak shape.

Objective To explore the diagnosis and treatment of thyroid malignant tumor (TMT) arising on basis of Hashimoto′s disease (HD).Methods 150 pathology proved HD patients admitted between 1976 and 1999 were retrospectively analyzed for the incidence of TMT.Results 15 HD patients were found suffering from thyroid carcinoma with a concurrent rate of 10%, and 3 with thyroid malignant lymphoma (TML) (2%). All postoperative TMT patients were followed up for an average period of 6 years, 15 TC patients were all alive without recurrence, and all TML patients died within 2 years.[WT5”HZ] Conclusion Surgical treatment of HD patient associated with TMT is indicated. The key to diagnosis and rational treatment are a detailed understanding its clinical feature, routine examination of serum antibodies and FNAC or frozen section in operation.

Objective To analyze the long term outcomes of antebrachial flap with a pedicle of the posterior interosseous artery Methods Ninety cases were followed up for 1～16 years, the indication and long term outcomes and dorsal aspect of the forearm were analyzed and evaluated retrospectively Results Eighty nine cases survived, except one case, the conteur of forearm and hand were satisfied Conclusion Antebrachial flap with a pedicle of the posterior interosseous artery is an optimal method to repair soft tissue defects of hand.

Objective To investigate the protective effect of aloin on inducible nitric oxide synthase (iNOS) and nuclear factor kappa B (NF-kB) synthesis of HaCat cells induced by ultraviolet B (UVB) irradiation. Methods The proliferation of HaCat cells was measured by MTT method. iNOS mRNA was detected by reverse transcriptase polymerase chain reaction (RT-PCR). NO production was assessed by spectrophotometric method, and expression of NF-kB P65 was measured by immunofluorescent staining. Results After irradiation with 30 mJ/cm~2 of UVB, proliferation of HaCat cells was decreased, and NO generation and iNOS mRNA synthesis in HaCat cells were increased. UVB irradiation could also activate the expression of NF-kB P65 and promote its translocation into nucleus. NO generation and iNOS mRNA synthesis were markedly down-regulated in a dose-dependent manner by pre-treatment with different concentrations of aloin. The activation of NF-kB P65 was inhibited while the proliferation of HaCat cells was increased. All the difference reached statistical significance (P

Cao reported that melagenine extracted from human placenta was effective in the clinical treatment of vitiligo, to elucidate the possible mechanism involved, melagenine and placenta peptide were added to melanocytes in the culture, and the culture without melagenine as control. The results obtained by MTT showed that melagenine can stimulate melanoeyte proliferation, its promoting rate was 42.5%, while placenta peptide got a promoting rate of 5.9%, the difference was significant (P
