Purpose:Taking tuberculosis as an example, this paper aims at to analyzing the level of reimburse-ment for infectious diseases care, and clarifying the government responsibility. Methods:In order to achieve the ob-jective of this research, UHC framework was used to analyze the security level. Result:The findings of this research reveal that TB in-patients' Compensation Ratio of the New Cooperative Medical Scheme ( NCMS) was lower than aver-age level of all the NCMS patients, the out-patients' was even lower. The categories of anti-tuberculotic for free was limited, the utilization was not as expected. Medical assistance covered few people in spite of its high level of reim-bursement. Conclusion:Based on the findings of this review, it has been revealed that the medical insurance didn't make a big difference in financial protection for patients with infectious diseases. As the treatment for of infectious diseases is a quasi-public good, the government has to shoulder the responsibility of improving the compensation ratio of the patients.

Objective To study the antigenicity of human thyrotropin receptor(hTSHR)amino terminus (amino acid 29~280)and its association with Graves' disease.Methods Total thyroid RNA was prepared from human normal thyroid tissue.RNA was then reversely transcripted and cDNA was subjected to PCR amplification.PCR product was cloned into pcDNA3.1 and the recombinant plasmid was named pcDNA3.1/hTSHR188~940bp. Balb/c mice were immunized with peDNA3.1/hTSHR188~940bp. The levels of serum thyroxin,anti-TSHR antibody(TRAb)and thyroid stimulating antibody(TSAb)were measured,and the pathological changes of thyroid tissue were also observed.Results A 753 bp fragment encoding hTSHR ectodomain amino end was obtained after PCR amplification.Confirmed by Hind Ⅲ restriction enzyme digestion and DNA sequencing,pcDNA3.1/hTSHR188~940bphad been constructed successfully,with the correct sequence and direction of hTSHR188~940bp.In the Balb/c mice treated with pcDNA3.1/hTSHR188~940bp,elevated TRAb in week 6(0.148±0.018)were observed compared with those at week o(0.106±0.006,P<0.01),and kept a higher level till week 10(0.134±0.011,P<0.01).T4 and TSAb index values were significantly increased in week 10.Serum T4 concentration increased from(41.02±7.97)μg/L in week 0 to(62.20±12.77)μg/L in week 10(P<0.01);TSAb index values rose from 0.864±0.076 at week 0 to 1.392±0.615(P<0.01).Thyroid pathological examination showed that proliferated thyroid follicular epithelial cells and foll icular eapacity increased.Inflammatory cells were occasionally found.Conclusions There are antigen epitopes in hTSHR ectodomain amino acid 29~280,which can stimulate the production of TSAb.And the latter induces hyperthyroidism and Graves' disease like manifestations.It suggests that hTSHR ectodomain amino acid 29~280 is closely associated with Graves' disease,and maybe one of important etiological factors leading to the disease.

OBJECTIVETo observe the protective effect of electroacupuncture (EA) at "Zusanli" (ST 36) on inflammatory injury induced by intestinal ischemia/reperfusion (I/R) in rats.
METHODSForty-eight Wistar rats were randomly divided into a sham injury group, a model group, an EA group and a sham EA group, 12 rats in each group. Intestinal I/R rat models were established by method of clamping with occlusion of superior mesenteric artery (SMA) for 45 min followed by reperfusion. The EA group was treated with EA (2.5 mA, 2 Hz/100 Hz, 0.5 h) at "Zusanli" (ST 36) 30 min before reperfusion, and at the same time, the sham EA group was treated with fast insertion at two non-meridian acupoints on skin surface (2 cm horizontally away from linea alba abdominis and about 5 cm paralleled to cartilago ensiformis downward). No interventions were added on the sham injury group and the model group. The degree of pathological injury in intestines, water rate of intestines, diamine oxidase (DAO) activity and intestinal mucosal blood flow (IMBF) were examined at 1 h and 3 h after reperfusion.
RESULTSAt 1 h and 3 h after reperfusion, the intestinal pathological injury in EA group was significantly attenuated compared with that in model group, and the intestinal water rate of (74.00 +/- 2.11)% and (78.78 +/- 0.80)% in EA group were significantly lower than (80.69 +/- 1.66)% and (83.17 +/- 2.08)% in model group (both P < 0.01), but DAO of (68.83 +/- 4.31) U/L and (47.84 +/- 5.57) U/L as well as IMBF of (152 +/- 5.8) PU and (139.8 +/- 6.1) PU in EA group were significantly higher than DAO of (32.86 +/- 4.72) U/L, (17.01 +/- 2.96) U/L as well as IMBF of (124.7 +/- 8.3) PU and (89.4 +/- 13.2) PU in model group (all P < 0.01). Meanwhile, the above mentioned changes in sham EA group showed no significant differences compared with those in model group (all P > 0.05).
CONCLUSIONElectroacupuncture can not only reduce the inflammatory injury induced by intestinal IR but also increase intestinal blood supply so as to protect the intestine function.

OBJECTIVETo study the clinicopathologic features of primitive neuroectodermal tumor (PNET) in female genital tract.
METHODSSix cases of PNET arising in female genital tract were retrospectively reviewed. The clinicopathologic features, immunohistochemical findings and EWS gene translocation study results were analyzed.
RESULTSThe age of patients ranged from 10 to 27 years (mean = 20 years). The sites of involvement included ovary (1 case), uterus (1 case), vulva (2 cases) and vagina (2 cases). The greatest diameter of the tumor ranged from 2 to 10 cm (mean = 5.4 cm). The tumor had nodular appearance and showed grayish-pink fleshy cut surface, accompanied by foci of hemorrhage and necrosis. Histologically, the tumor was composed of malignant small round cells with indistinct cell borders, hyperchromatic nuclei, dense chromatin, tiny nucleoli and scanty cytoplasm. The tumor cells were arranged in sheets or lobules. Homer-Wright rosettes were identified in 1 case. Immunohistochemical study showed that the tumor cells were positive for CD99, FLI-1 and CD56 (6/6). Focal expression of vimentin (5/6), NSE (5/6), nestin (4/6), synaptophysin (4/6), S-100 protein (2/6) and chromogranin A (1/6) was also demonstrated. EWS gene translocation was detected in 5 cases studied. Follow-up information was available in 2 patients (7 and 17 months of follow up, respectively). One of them died of tumor metastasis 17 months after diagnosis. The other patient was still alive.
CONCLUSIONSPNET arising in female genital tract is rare. It mainly involves ovary, uterus, vulva and vagina. Immunohistochemical study using a panel of antibodies and fluorescence in-situ hybridization play an important role in definitive diagnosis of this rare malignancy.

Human beta2-microglobulin (beta2m) is the light chain of major histocompatibility complex (MHC) class I molecule. High-yield production of this protein is a prerequisite to the preparation of MHC I tetramer. The present study aims to obtain recombinant human beta2m expressed in Escherichia coli (E. coli), for the purpose of preparing MHC class I tetramers. For cloning of human beta2m gene, a pair of specific primers was designed based on the published sequence of this gene and the cDNA of full coding region for beta2m precursor was obtained by RT-PCR from the total RNA of human leukocytes. The amplified cDNA was subsequently cloned and its sequence was confirmed by DNA sequencing analysis (the sequence has been deposited in GenBank with accession number of AY187687). The prokaryotic expression vector containing a gene encoding mature beta2m was constructed by inserting the DNA fragment, which was generated by PCR reaction with the cloned beta2m gene as template, into an IPTG-inducible expression vector pET-3c plasmid. The first eight codons for N terminal amino acid residues of beta2m were optimized for its expression in E. coli. The complete sequence of beta2 m gene in the expression vector was verified by DNA sequencing analysis. High-yield expression of beta2m was achieved in E. coli transformed with the expression vector, and most of the recombinant beta2m existed in the inclusion body after IPTG induction. The inclusion body was washed extensively and beta2m in the inclusion body was solublized with 8 mol/L urea. The beta2m was refolded by dialysis and purified by ion-exchange chromatography (Q-Sepharose). Western blotting assay indicated that the polyclonal antibody against human native beta2m could react specifically with the recombinant protein. The purified protein appeared as a single band on both SDS-PAGE and Western blotting, indicating that it was chemical and antigenic pure. This work establishes a convenient approach for renaturation and purification of large quantity of recombinant beta2m which is identical to the native protein without any tags fused except for a methionine residue at the amino terminus. This provides the basis for the preparation of MHC tetramers.

OBJECTIVETo study the effect of natural killer (NK)-cell on reconstitution of hematopoiesis and immunity in mouse allogeneic bone marrow transplantation (allo-BMT).
METHODSLethally irradiated BALB/c (H-2(d)) mice were transplanted with C57BL/6 (H-2(b)) bone marrow plus peripheral T cells and/or NK cells. Recipients CD34(+) cells and H-2K(b+), CD3(+) and CD19(+) cells were detected by flow cytometry, peripheral white blood cell (WBC) by auto-cytometry, and the survival rates, engraftment, hematopoietic and immune recovery were observed.
RESULTSIn the transplantation with NK cell infusion group, the survival rates, the WBC and CD34(+) cell counts, and the H-2(b+) and CD19(+) cells were significantly higher than that in without NK cell infusion group (P < 0.01). Twenty-eight days after transplantation, the CD3(+) cells in the NK cell infusion group [(33.69 +/- 3.36)%] were lower than that in without [(50.4 +/- 5.06)%] (P < 0.01), and there was no longer difference between these groups 60 days after transplantation (P > 0.05).
CONCLUSIONIn mouse allo-BMT, alloreactive NK cell enhances engraftment, promotes reconstitution of hematopoiesis and immunity and increases survival rates.
