Antithyroid drugs(ATD)is the main treatment for hyperthyroidism and its adverse reactions have been much concerned by physicians. Methimazole(MMI)and propylthiouracil(PTU)are the two common antitithyroid drugs used currently. Generally, the ATD are safe and effective, though their clinical adverse reactions are also relatively common. The toxic effects include liver damage and leukocytopenia, antineutrophil cytoplasmic antibody-associated pulmonary small-vessel vasculitis, hypoglycemia, allergic reactions, muscle impairment,and so on. They are usually reversible and disappear spontaneously when the drug is discontinued. However,the serious rare side effects can also occur and there may have potentially deadly threatening effects which need to be cautious for the clinicians. MMI is usually preferred over PTU because it has significantly fewer side effects. And unlike the dose-dependent side effects of MMI, there has no significant correlation between adverse reaction and drug dosage in using PTU. Moreover, PTU has more severe hepatotoxity than MMI, even fatal liver impairment and liver failure. The risk of liver damage from PTU is an important concern, particularly in children. For this reason, MMI is the first choice for treating children with hyperthyroidism.

Parathyroid carcinoma is a rare endocrine tumor.Clinical manifestations are varied with multiple organs involved,mainly due to hypercalcemia.So far the etiology and pathogenesis of parathyroid carcinoma are still unclear and preoperatively diagnosis is difficult.Technetium-99 m sestamibi scan and ultrasound can help to find the early lesions.Complete surgical resection with suspicious involved lymph nodes is the recommended treatment.Parathyroid carcinoma is insensitive to chemotherapy and radiotherapy.New immune therapy yields unsure efficacy.Therapeutic effect and prognosis mainly depend on primary surgical resection of the tumor.The disease recurs in more than 50％ of patients with poor prognosis.

Objective To provide the basis for determining the suitable collecting time of safflower. Methods To measure the contents of saflor yellow-A in safflower crude drug from different collecting time in one day by HPLC. Results Only saflor yellow-A has big change. By experimental analyzing samples of different year and region, A bright time collecting in the flok, the content of saflor yellow-A in medicine assured higher. Conclusion A bright time collecting has some scientific basis.

Objective A HPLC method to determine the content of Baicalein in Tangtai capsule was established. Method The separation was performed by Zorbax C18 column with acetonitrile and 0.5% phosphorice acid. The elution program was 1~15 min, 15%～60% acetonitrile. The flow rate was 1 mL/min and column temperature was 25 ℃. Content was detected at a wavelength of 280 nm. Result The linear range was 0.936～18.72 ?g, regression:Y =4849.53X-0.9593 (r=0.9999). The average recovery rate was 98.29% and RSD was 0.97% (n =5). Conclusion The method is simple, accurate and reproductive, and can be used for determining Baicalein in Tangtai capsule.

Objective: To explore the therapeutic efficacy and mechanism of transcutaneous electrical acupoint stimulation (TEAS) for menopausal insomnia. Methods: A total of 80 patients with menopausal insomnia were randomly divided into a control group and an observation group, with 40 cases in each group. The patients in the control group received conventional Western medication treatment, and the patients in the observation group received TEAS on the basis of conventional Western medication treatment. The treatment for both groups lasted for 4 weeks. Before and after treatment, Pittsburgh sleep quality index (PSQI) and modified Kupperman scale were evaluated, and the serum levels of estradiol (E2) and follicular stimulating hormone (FSH) were measured. The therapeutic efficacy was evaluated after treatment. Results: After treatment, the total effective rate of the observation group was significantly higher than that of the control group (P<0.05); in the control group, the improvement of PSQI score was significant (P<0.05), while the change of modified Kupperman score was insignificant (P>0.05); the PSQI and Kupperman scores in the observation group were significantly improved after treatment (both P<0.05), and there were significant differences between the observation group and the control group in PSQI and Kupperman scores (both P<0.05). After treatment, the serum E2 and FSH levels in the control group were not statistically different from those before treatment (both P>0.05); the serum E2 level was significantly increased (P<0.05), and the FSH level was decreased (P<0.05) in the observation group after treatment, and the between- group differences in serum levels of E2 and FSH were significant (both P<0.05).Conclusion: TEAS plus conventional Western medication in treating menopausal insomnia is effective, and can significantly improve the symptoms of insomnia and menopause, which may be related to the regulation of serum E2 and FSH levels.

Objective To explore the association of expression between the longevity gene SIRT1 and the forkhead transcription factor FOXO1 in the beta cell of islet in rat,and provide the basic prevention and cure rationale for the type 2 diabetes mellitus.Methods Eleven male SD rats of 18 months old were randomized into two groups:6 in calorie restriction(CR)group and 5 in the control group.After 6 months' breeding,the caudal end of islet was collected.The expression and location of SIRT1,FOXO1 and insulin were detected by immunohistochemistry;sections of pancreas were stained for senescence-associated ?-galactosidase(SA-?-Gal)to identify cell senescence of pancreatic islets.Results SIRT1 and FOXO1 were expressed in both the kytoplasm and nucleus,while insulin and ?-Gal were located in the kytoplasm.Compared with the control group rats,there was higher SIRT1 expression(P0.05)expression was detected in the beta cells of CR group rats.The lower positive rate of FOXO1 located in the nucleus the higher expression of SIRT1 in the rat beta cell of islet.Conclusion Calorie restriction could induce the high expression of SIRT1 in the rat beta cell of islet,and we think SIRT1 may delay the senescence process of rat beta cell through the repression of transcription factor FOXO1;it's beneficial to the prevention and cure for type 2 diabetes mellitus.
