Thyroid hormones (TH) play an imp or tant role in the development and maturity of the mammalian brain. Maternal TH de ficiency, even subclinical hypothyroidism, leads to poor neurodevelopment of the fetus. Screening of pregnant women for hypothyroidism is recommended. Identific ation of the TH-responsive genes in the developing brain and investigation on t heir functions are helpful to provide insights into the molecular mechanisms by which TH influence brain development.

Objective To investigate the correlation between the glycosylated hemoglobin (HbA1c) detection data and hemo‐rheological indicators in diabetes patients to provide reference basis for its treatment and prevention .Methods One hundred and forty‐two patients with typeⅡdiabetes mellitus(T2DM ) in the hospital were selected as the research subjects and divided into the A group(69 cases ,better control) and B group(73 cases ,poor control) according to the HbA1c detection results .Contemporaneous 70 healthy individuals undergoing physical examination were selected as the control (C group) .The detection results of HbA1c ,hemo‐rheology and biochemical indexes were performed the contrastive analysis .Results Except hematocrit and erythrocyte deformation index without statistical difference among 3 groups(P>0 .05) ,the other hemorheologic indicators had statistical differences among 3 groups(P<0 .05) .No matter the HbA1c level in T2DM patients ,the hemorheological indexes ,triglyceride and total cholesterol were higher than those in the healthy people ,When the HbA1c leve was poorly controlled ,the increase degresss of various indexes were more significant .Conclusion The abnormality of hemorheology indices exist in most of the patients with diabetes mellitus .It is recommended that clinic should monitor the HbA1c level for long term and strictly observe the change of hemorheology indexes to guide the clinical treatment for reaching the effects of early vascular protection and prevention of diabetic complications .

Thyroid-stimulating hormone receptor(TSHR)is an important autoantigen whose cleavage and shedding can induce autoimmunity.The TSHR is the main functional receptor of the thyroid.The shedding of the ? subunit plays an important role in the forming of TSAb and balancing between TSAb and TBAb.Research on the cleavage and shedding of the TSHR extracellualar domain helps to gain a deep insight into the structure and function of TSHR,illuminate the pathogenesis of autoimmune thyroid disease and find out a new therapy.The structure of TSHR,the mechanism and the significance of its cleavage and shedding are reviewed in this article.

OBJECTIVE To study infection and drug resistance of Mycoplasma from female genital tract.METHODS Mycoplasma in cervical secretion from inflammed female genital tract were identified by cultivation,and the sensitivities to antibiotics were also performed.RESULTS Mycoplasma were detected in 318 specimens among 588 patients with genital tract inflammation(54.1%),among which Ureaplasma urealyticum(Uu) accounted for 312(98.1%),and Mycoplasma hominis was 6(1.9%).The resistance to 12 kinds of antibiotics indicated that the sensitivities to 8 kinds of antibiotics were higher than 80% and the sensitivities to erythromycin,spiramycin and tetracycline were the lowest.CONCLUSIONS The infectious rates of Uu are on big rise in female genital tract with inflammation and the resistant strains increase continuously.

Objective To evaluate advantages and safety of bipolar electrodes for the treatment of submucosal myoma of uterus.Methods Three hundred patients with submucous myoma of uterus were performed with bipolar electrodes under hysteroscope,including 212 cases of type 0 submucous myoma,54 cases of type ?,and 34 cases of type Ⅱ.Results Total volumes of uterine distention fluid used during operation were 500-2000 ml(mean,626 ml);operation time was 20-50 min(mean,25 min);intraoperative blood loss was 10-20 ml.Cardio-cerebral syndrome occurred in one case and was relieved by timely treatment.There was no operation discontinuation as a consequence of pain.The diameters of resected myomas were 3-5 cm,with an average of 3.8 cm.The postoperative diagnosis showed leiomyosarcoma in 1 case and was performed by radical hysterectomy resection combined with a pelvic lymphadenectomy at 10 day postoperatively.During the follow-up period of 1-24 months in 277 cases,40 cases(type I in 12 cases;type II in 28 cases) needed hysteroscope operation again.Conclusions Hysteroscopic resection for submucosal myoma of uterus with dipolar electrodes has advantages of safety,minimal invasion,quicker recovery,higher efficiency,so it is worthy of being recommended.

Objective To explore the clinical effects of hysteroscopy combined with mifepristone on the diagnosis and treatment of abortive remnants.Methods A total of 56 patients with abortive remnants,who had undergone uterine curettage after the abortion,were treated with mifepristone combined with hysteroscopy.Before hysteroscopy,mifepristone was taken orally at a dose of 100 mg daily(50 mg,Bid) for 7 days.After the surgery,those who still had remnants in the uterus were given mifepristone at the same dose for 14 days.Results No patient had complication during and after the hysteroscopy except for one,who had abortive remnants at the uterine horn,experienced blood loss of 200 ml.In 40 patients,the abortive remnants were removed completely by hysteroscopy.Two weeks after the surgery,laboratory examination of the patients showed normal blood ?-hCG,and B-ultrasonography revealed no space-occupying mass in the uterus.In the other 16 patients,remnants were detected in the uterine horns after the hysteroscopy,and mifepristone was prescribed.These patients received reexaminations 2 months after the operation,and no abnormal blood ?-hCG or remnants in the uterus was found.Among the 56 patients,33 were followed up for 1-6 months(mean,3 months).During the follow-up,their symptoms including vaginal bleeding or drainage,amenorrhea,and abdominal pain disappeared,and the menstruation became normal.Conclusions Hysteroscopy combined with mifepristone is an effective measure to diagnose and treat abortive remnants.

Objective: To modify the mono-antigen DNA vaccine of Mycobacterium tuberculosis with ubiqutin, so as to obtain more potent immune response. Methods: We constructed Mycobacterium tuberculosis MPT64 antigen DNA vaccine (pM) and ubiquitin-MPT64 fusion gene DNA vaccine (pUM). The constructed DNA vaccines were intramuscularly inoculated into female BALB/c mice separately. The serum antibodies(including IgG, IgG1,and IgG2a), cytokines (IFN-γ, IL-4) and cytotoxic T lymphocyte(CTL) response were determined in immunized mice. Results: The IgG level in the pM group was higher than that in the pUM group(P<0.01) and the ratio of IgG2a/IgG1 in the pM group was lower than that in the pUM group([2.16±0.3] vs [4.48±0.4],P<0.05). The IFN-γ level was higher (P<0.01) and the IL-4 level was lower (P<0.01) in the pUM group than those in the pM group. Furthermore, the pUM group had higher CTL activity than the pM group. It was indicated that the fusion gene DNA vaccine induced weaker humoral immune response but stronger cellular immune response compared to single gene DNA vaccine. Conclusion: The fusion gene DNA vaccine constructed in the present study might be more effective for prevention against tuberculosis than the single gene DNA vaccine.
