OBJECTIVETo observe the clinical efficacy of Jiakangling Capsule (JC) combined with reduction of 1311 in treatment of Graves hyperthyroidism.

METHODSTotally 387 Graves hyperthyroidism patients were randomly assigned to the treatment group (200 cases) and the control group (187 cases). Patients in the treatment group took JC combined with reduction of 131I. The 131I dosage per gram of thyroid tissue was 50-80 microCi. They additionally took JC one week after taking 1311 for one consecutive month. Patients in the control group took 131 routinely as one disposable treatment. The 131I dosage per gram of thyroid tissue was 70-120 microCi, without using JC or other anti-thyroid drugs. All patients were reexamined after 24-month treatment. Whether hyperthyroidism was cured, incurred, or permanent was observed. Efficacies of thyroglobulin antibody (TGAb) and thyroid microsome antibody (TMAb) were compared between the two groups.

RESULTSCompared with the control group, the incurred ratio increased in the treatment group [3.2% (6/187) vs. 16.0% (32/200), P < 0.01], the incurred ratio of strong positive TGAb and TMAb patients increased [3.5% (2/57) vs. 27.1% (16/59), P < 0.01], the permanent hypothyroidism ratio decreased [21.1% (12/57) vs. 3.4% (2/59), P < 0.05 ].

CONCLUSIONJC combined with reduction of 1311 was superior in treating Graves hyperthyroidism induced permanent hypothyroidism than routine 1311 treatment, especially for strong positive TGAb and TMAb patients.

JINLANBAO (JLB), a preparation extracted from the Pecten Argopecten irradiaus and some Chinese medicinal herbs,has been reported to have several immuno-mod-ulatory effects in mice In this paper,the influence of JLB on the immuivlogcai functions in mice is presented. The results showed that JLB could enhance the phagocytosis of intraperi-toneal macrophages (Mo) inhibited by methyl-prednisone,increase the IgM level in CTX-de-pressed cells in a dose-dependent manner in the medium-dose and high-dose group. JLB has been found to have a two-way regulatory effect on ConA-induced T-lyrophocytes prolifera tion, tea promoting effect in low dose group,and an inhibiting effect in high dose group. As an immunopotentiator, the potential values and prospects for the developing of JLB should be paid attention to in pharmaceutical sciences.

OBJECTIVEThis study investigates the immune status of T helper (Th) 17 cells in mice with periodontitis.

METHODSSeven-week-old C57BL/6 female mice were randomly divided into the control and periodontitis groups. Each group comprisedfour mice. Experimental periodontitis was induced in mice by oral infection with Porphyromonas gingivalis in the periodontitis group. Phosphate-buffered saline solution was used in the control group. All mice were sacrificed 4 weeks after the last P. gingivalis infection. CD4⁺retinoid-related orphan receptor (ROR) γτ⁺(Th17) cells were analyzed by flow cytometry. The protein expression of Th17 cell-related cytokine interleukin (IL)-17A was detected by enzyme-linked immunosorbentassay (ELISA).

RESULTSFlow cytometry showed that the percentage of CD4⁺RORγτ⁺(Thl7) cells in all CD4⁺ cells and the cell number in gingival tissues, cervical lymph nodes (CLNs), and the peripheral blood obviously increased (P < 0.01) in the periodontitis group. ELISA showed that compared with the control group, the periodontitis group exhibited an obvious increase in the protein expression of IL-17A (P < 0.05).

CONCLUSIONTh17 cell-mediated cell response is enhanced, and the gingival tissues, CLNs, and the peripheral blood are probably the main locations of Thl7 cell-mediated cell response during the development of periodontitis.

Objective To Study the effects of Danhong mixture on water and calcium contents in brain tissue of rats with acute cerebral ischemia reperfusion injury.Methods 60 healthy SD rats were randomly divided into 6 groups,respectively,a sham operation group,a model control group,and 4 drug treatment groups.Models of cerebral ischemia reperfusion injury were established by 4 blood-vessel method,and administrated with different doses of Danhong mixture injection and compound salvia miltiorrhiza injection.Effects of Danhong mixture on water and calcium content in brain tissue of rats with acute cerebral ischemia and reperfusion injury were observed.Results Water and calcium content in brain tissue of rats with acute cerebral ischemia reperfusion injury were significantly decreased in Danhong mixture of high dose group (P＜0.01),(water was 75.84％ and calcium was 114.56 μg/g).Water and calcium content were also significantly decreased in Danhong mixture of medium dose group (P＜0.01),(water was 80.13％ and calcium was 132.35 μg/g)Water and calcium content showed decreasing tendency in Danhong mixture of low dose group,but without statistical significance,its numerical value was respectively 73.94％ and 106.32 μg/g.Conclusion Danhong mixture can reduce water and calcium content in brain tissue of rats with acute cerebral ischemia reperfusion injury,which indicated its neuroprotective effects.

Objective:To investigate regulatory T(Treg)cell-mediated immune response in mice with periodontitis.Methods:8 sev-en-week old C57BL/6 female mice were randomly divided into 2 groups(n =4).Periodontitis was induced in mice by oral infection with Porphyromonas gingivalis(P.gingivalis).Carboxymethyl cellulose(CMC)was used for the sham control mice.All mice were sacrificed 4 weeks after the last P.gingivalis infection.CD4 +forkhead box P3 (Foxp3)+ cells were analyzed by flow cytometry.The protein ex-pression of TGF-1 and IL-1 0 was detected by ELISA.Results:Periodontitis mice showed an obvious decrease in the percentage of CD4 +Foxp3 + cells in CD4 + T cells in gingival tissues,cervical lymph nodes(CLNs)and peripheral blood(P <0.01 ).Moreover,peri-odontitis mice had an obvious increase in the expression of TGF-1 and IL-1 0 in gingival tissues,CLNs and serum(P <0.05).Conclu-sion:Treg cell-mediated immune response is weakened in the mice with periodontitis.Gingival tissues,CLNs and the peripheral blood are probably the main source of Treg cells during periodontitis.

Objective To investigate the relationship of dynamic enhanced MRI findings of breast cancer and axillary lymph node metastasis. Methods Clinical and dynamic MRI data of 79 patients with breast cancer (31 with and 48 without axillary lymph node metastasis) were retrospectively analyzed. MRI findings of the lesions were systematically described according to breast imaging reporting and data system (BI-RADS) standards. Then the relationship of MRI findings and axillary lymph node metastasis were analyzed. Results MRI showed mass-like lesions in 71 cases (71/79, 89.87%), among them axillary lymph node metastasis was pathologically proved in 27 cases. There were significant differences in location of lesions between patients with or without metastasis axillary lymph node metastasis (P<0.05), while no significant difference in types of lesions was detected (P>0.05). There were significant differences in the marginal morphology, early enhancement pattern and mass maximum diameter of mass-like lesions between patients with or without axillary lymph node metastasis (all P<0.05), whereas no significant difference of lesion shape, internal enhancement mode nor delay phase time-signal intensity curve type was observed (all P>0.05). Conclusion The lesion's location, size of mass, marginal features and early enhancement patterns showed on dynamic enhanced MRI are associated with axillary lymph node metastasis of breast cancer.

Objective To investigate the effects of TLR7 on imiquimod induced apoptosis of THP-1 derived macrophages.Methods Three cell lines ( THP-1 derived macrophages, MDCK cell line and HUVEC cell line) with different capabilities of expressing TLR7 were selected.The survival rates of cells af-ter the treatment with different concentrations of imiquimod were detected by MTT assay.The levels of IL-6 in the supernatants of TLR7 inhibitor chloroquine or TLR7-siRNA treated cells were detected by enzyme-linked immunosorbent assay.The apoptosis of cells was detected by flow cytometry after inhibiting the ex-pression of TLR7.Results Imiquimod induced the apoptosis of THP-1 derived macrophages, MDCK cell lines and HUVEC cell lines.The levels of IL-6 were significantly decreased as the expression of TLR7 was inhibited by treating THP-1 derived macrophages with chloroquine or TLR7-siRNA.Treating THP-1 derived macrophages with chloroquine or TLR7-siRNA did not affect the cell apoptosis induced by imiquimod.Con-clusion Imiquimod could induce the apoptosis of THP-1 derived macrophages through TLR7 independent pathway.

Objective To provide scientific evidences for Zika virus detection by clarifying the means by which Zika virus was discharged and the duration of corresponding processes. Methods Various samples of Zika cases were collected at different times and detected by using real-time RT-PCR. The positive samples were inoculated into cells and suckling mice through intracranial injection. The whole genome se-quences of those isolated Zika virus strain were sequenced and the results were further analyzed by comparing with the sequences of Zika virus from GenBank. Results The positive rates of Zika virus in urine, saliva and serum samples were 82. 4% (14/17), 82. 4% (14/17) and 52. 9% (9/17) respectively. The longest period of detected presence of Zika virus was found in urine samples amongst the three types of samples, fol-lowed by saliva and serum samples. Six Zika virus strains were isolated from 9 positive serum samples. Phy-logenetic analysis showed that the six genomes of Zika virus all belonged to Asia lineage, but located in two branches by Samoa and Venezuela strains. Conclusion This study indicated that urine, saliva and serum all could be used as the samples for routine detection of Zika virus. Urine and saliva samples showed higher detection rates of Zika virus RNA in comparison to serum samples, while Zika virus could be easily isolated from positive serum samples. Suckling mice were better for Zika virus isolation than cell lines.
