ABSTRACT
OBJECTIVE:To compare the clinical efficacy of raloxifene and clomiphene in the treatment of polycystic ovary syndrome(PCOS)complicated with infertility. METHODS:In retrospective study,clinical information of 137 PCOS patients with infertility in our hospital during Jun. 2012-Feb. 2015 were selected and divided into raloxifene group(70 cases)and clomiphene group(67 cases)according to therapy plan. Raloxifene group received Raloxifene tablet 120 mg at the fifth day of menstrual cy-cle,qd,for consecutive 5 d. Clomiphene group received Clomiphene citrate capsule 100 mg at the fifth day of menstrual cycle, qd,for consecutive 5 d. Both groups received B-ultrasound to detect the follicular diameter and endometrial development at the twelfth day of menstrual cycle. When endometrial thickness was ≥7 mm and the diameter of one follicle was ≥18 mm at least,all patients received abdominal subcutaneous injection of Triptorelin acetate injection 0.1 mg to induce ovulation;after 48 h,ovulation was confirmed by B ultrasound. The patients with insufficient luteal function should take dydrogesterone 10 mg as appropriate,q12 h,till 15 d after ovulation. The endometrial thickness,the number of follicles with diameter≥18 mm and follicular maturation time were compared between 2 groups on the day of injection. The sex hormone levels before treatment and on the day of injection,as well as ovulation,outcome indexes and the occurrence of ADR in 2 groups were compared. RESULTS:The endometrial thickness of raloxifene group was greater than that of clomiphene group;the number of follicles with diameter ≥18 mm was more than clo-miphene group;the follicular maturation time was shorter than clomiphene group,with statistical significance(P0.05). Compared to before treatment,there was no statistical significance in serum levels of P,E2,FSH or LH in 2 groups on the day of injection(P>0.05). Serum levels of LH in 2 groups were decreased significantly,and serum level of LH in raloxifene group was significantly lower than in clomiphene group,with statistical significance(P0.05). There was no statistical significance in the total incidence of ADR (5.71% vs. 8.96%)between 2 groups(P>0.05). CONCLUSIONS:Raloxifene has better ovulation induction effect than clomi-phene,and it can improve the sex hormone levels of PCOS patients with infertility,with few ADR,and similarity in long-term clinical effect with clomiphene.
ABSTRACT
objective To evaluate the distribution and significance of IgG subclasses of antithyroglobulin antibody in sera from patients with Hashimoto thyroiditis.Methods Sera from 112 patients with Hashimoto thyroiditis were collected and patients were divided into 3 groups,i.e.hypothyroidism,subclinical hypothyroidism and euthyroidism.Antigen specific ELISA was used to detect the distribution of IgG subclasses of antithyroglobulin antibody.Results The positive rates of IgG subclasses of TgAb were IgG1 90.2%,IgG2 58.0%,IgG3 19.6%and IgG4 87.5%respectively.The mean geometric titers of IgG1 in sera from patients with hypothyroidism and subclinical hypothyroidism were 1:450.8 and 1:245.5 respectively,both being significantly higher than that with euthyroidism(1:8.7,P＜0.01).The mean geometric titers of IgG2 in sera from patients with hypothyroidism and subclinical hypothyroidism were 1:37.3 and 1:3.2 respectively,both being also significantly higher than that with euthyroidism(1:0.2,P＜0.01 and P＜0.05 respectively)and that with hypothyroidism was significantly higher than that with subclinical hypothyroidism(P＜0.05).Conclusion The distribution of IgG subclasses of antithyroglobulin antibody in sera from patients with Hashimoto thyroiditis was predominantly IgG1,IgG2 and IgG4.High titers of IgG1 and IgG2 implicated the possibility of development from subclinical hypothyroidism to overt hypothyroidism.
ABSTRACT
@#ObjectiveTo investigate the diagnosis and correlative factors of suspected severe acute respiratory synd rome (SARS) cases, and finally, complete the diagnosis and treatment.MethodsTo analyze the clinical, laboratory data,chest radiog raph and treatment of 100 suspected SARS cases.ResultsAmong 100 suspected SARS cases,66 were diagnosed as SARS,4 were mycoplasma l pneumonia, 2 were pulmonary tuberculosis,the others were general bacteria pne umonia.Conclusions SARS hasn't characteristic clin ical manifestation.Because there is not a gold diagnosis standard up to now, the disinfection and isolation of suspected SARS cases should be treated as SARS c ases. In order to prevent missed and misdiagnosis, the diagnosis and treatment s hould be synthetically thought.
