Objective To compare the curative effects between microwave endometrial ablation (MEA) and total hysterectomy for the treatment of menorrhagia. Methods Sixty patients with menorrhagia were divided into 2 groups with 30 patients in each group, either to MEA or to total hysterectomy (control group). The intraoperative blood loss, operating time, sparing or unsparing of uterus, and length of recovery of the 2 groups were compared. Results The effective rates for menorrhagia, operating time, and mean blood loss of MEA group and control group was 96% (29/30) and 100% (30/30) (?2=0,P=1.0), (4.0?1.1) min and (68.3?1.9) min (t=-160.42, P=0.00), 0 ml and 50 ml, respectively. Conclusions MEA is a novel minimally invasive method for menorrhagia, and its curative effects are similar to that of total hysterectomy. When considered in terms of sparing of uterus and postoperative recovery, MEA is obviously superior to total hysterectomy.

Objective To analyze the clinical presentation and the effects on both mothers and fetuses with HELLP syndrome induced hyregtensive disorder complicating pregrancy and to investigate the effective methods for diagnosis and treatment. Methods 15 cases of HELLP syndroms were retrospectively analyzed on material and perinatal outcomes. Results In 15case of women with HELLP syndrome, all of them presented antepartum HELLP. Mean gestational age at delivery was 34 weeks. Severe maternal complications included placental abruption,DIC ,postpartum hemorrhage,fetal distress, et al. All of them underwent cesaresn section and required transfusions with blood or blood products. 1 case of perinatal death was related to placental abruption. Conclusion HELLP syndrome is a severe obstetric complication. Better prognosis may be achiveved by early diagnosis, synthetic therapy and optimal termination of pregnancy.

Method Take the antifungal substance as experimental materials, and test its minimum inhibitory concentration and minimum bactericidal concentration on four fungi strains including Saccharomyces cerevisiae, Penicillium citrinum, Aspergillus niger, Rhizopus sp. Aspergillus niger was used as indicator strain to measure the biological activity and stability of the antifungal substance. Results The results showed that the MIC of the antifungal substance on four fungi strains including Saccharomyces cerevisiae,Penicillium citrinum,Aspergillus niger,Rhizopus sp were 1.25, 2.5, 3.75 and 3.75μg/mL, respectively. The MBC of the antifungal substance on four fungi strains were 2.5, 10, 17.5 and 17.5μg/mL, respectively. Linearity regress equation of the antifungal substance in Aspergillus niger was y=26.963 x-27.6,R 2=0.9991. The antifungal substance was pH-stable, heat-stable but ultravio1 et-sensible. Conclusion The results from this study will porvide useful information for the further extraction and analysis on the bioactive compound.

Objective To evaluate the efficacy of the parathyroidectomy (PTX) in the treatment of severe secondary hyperparathyroidism (SHPT) with Sagliker syndrome (SS). Methods A retrospective review was undertaken among 212 SS patients underwent PTX in our hospital and with more than 3 years' follow up. The definitions of the efficacy were based on the postoperative intact parathyroid hormone level (iPTH). Cure showed that the iPTH was ＜ 150 ng/L; marked effectiveness was 150-300 ng/L; effectiveness was 301-500 ng/L;ineffectiveness was ＞500 ng/L. The status was defined as persistent SHPT if iPTH was ＞ 150 ng/L after surgery. The status was considered as SHPT recurrence if iPTH was ＜ 100 ng/L in the first week after surgery, and gradually increased and ＞ 150 ng/L with the follow-up. Results ( 1) Ten patients were involved and the average dialysis time was 142 months [male/female: 4/6; age 30-54 (39. 3 ± 10. 4) years]. All patients had severe bone and joint pain, accompanied with progressive facial increases, chicken breast, kyphosis, hip bone deformities, and body height shortening. (2) Preoperative tests: the median of iPTH 2000(1800-2863) ng/L; serum calcium (2. 45 ±0. 21) mmol/L, phosphorus (2. 19 ±0. 51) mmol/L, alkaline phosphatase ( ALP) (1189. 8 ± 780. 0) IU/L. Two to four enlarged parathyroid glands were confirmed by ultrasound and 99Tcm-MIBI parathyroid scintigraphy. ( 3 ) Surgical procedures: local or general anesthesia for PTX. Supplement with calcium and calcitriol implemented low serum calcium after PTX. (4) Follow-up: symptoms, including bone pain, muscle weakness, skin itching, and insomnia, were significantly improved after surgery. Transient hoarseness occurred in 2 cases. The iPTHs of all patients were decreased significantly after surgery. The median of iPTH was 55.5 ( 10-967) ng/L at 1 month post PTX, and was significantly less than prior to PTX (P＜0. 001). Eight patients were cure , 1 marked effectiveness ,and 1 ineffectiveness. Two patients were persistent SHPT, and 1 died of heart failure in the 4th year after PTX. The development of bone deformities was stopped and malnutrition was improved in long-time follow up. The level of iPTH 135(28-390)ng/L(P＜0. 001 ) , serum calcium, phosphorus, and ALP showed normal in the third year. The SHPT recurrence was appeared in the 2nd and 3rd year in 2 out of 8 patients, respectively. Conclusions Total PTX can effectively treat SS by SHPT. It can improve prognosis for patients, such as bone pain disappearing, bone deformities stopping and malnutrition improving, etc. The level of iPTH may rise again in some patients in the future. Therefore, more attentions should be paid to monitoring.
