OBJECTIVE:To investigate the effect and safety of Shengmai injection on myocardial function of patients with gen-eral anesthesia of hysterectomy. METHODS:40 patients underwent hysterectomy were randomly divided into observation group and control group with 20 cases in each group. Both groups received general anesthesia induction of fentanyl citrate and rocuroni-um,and inhalation anesthesia of propofol. Observation group was given Shengmai injection 1 ml/kg,ivgtt;control group was given same dose of 0.9%Sodium chloride injection,ivgtt,before anesthesia. Mean arterial pressure(MAP),heart rate(HR),central ve-nous pressure(CVP),blood oxygen saturation(SpO2),the levels of MDA,SOD and NOS were compared between 2 groups be-fore operation(T0),before anesthesia induction(T1),reaction during(T2),after operation(T3). The occurrence of ADR was also observed. RESULTS:There was no statistical significance in MAP and HR between 2 groups at T0 and T1 (P>0.05). MAP and HR of observation group was significantly higher than those of control group at T2 and T3,with statistical significance(P<0.05). There was no statistical significance in CVP and SpO2 between 2 groups at different time points(P>0.05). There was no statistical significance in MDA,SOD and NOS levels between 2 groups at T0(P>0.05). MDA and NOS levels of 2 groups increased signifi-cantly at T1,T2 and T3,while SOD level decreased significantly;MDA and NOS level of observation group were lower than the control group while SOD level was higher than control group at T1,T2,with statistical significance (P<0.05). No obvious ADR was found in 2 groups. CONCLUSIONS:Shengmai injection can maintain stable HR and MAP,and reduce the oxide in patients underwent hysterectomy surgery so as to protect myocardial function with good safety.

Thyroglossal duct carcinoma is a malignant tumor which occurs in the thyroglossal duct cyst. The incidence of thyroglossal duct carcinoma has been reported as approximately 1%. Up to now, just about 250 cases of thyroglossal duct carcinoma have been reported in the literature,most of which are single case reports and small case series. In most cases, the diagnosis of the thyroglossal duct carcinoma is not made until the histologic examination after surgery operation. The preoperative examination such as CT or fine needle aspiration cytology can help the preoperative diagnosis. But the surgical treatment for the thyroglossal duct carcinoma is still controversial. Now we report a case of a thyroglossal duct carcinoma combined with systemic lupus erythematosus. The patient herself found an anterior neck mass in the median submental region one year ago. The preoperative CT examination suggested thyroglossal duct cyst with pouch canceration(papillary carcinoma). Then she underwent a Sistrunk procedure and level I neck dissection, and the histopathological diagnosis was thyroglossal duct carcinoma. The patient was treated with levothyroxine therapy at suppressive dose after the surgery. Now the patient is at regular follow-up with no relapse occur.
