Objective To evaluate the impact of bilateral ovariectomy in post-menopausal women by comparison of climacteric symptoms before and after operation. Methods Post-menopausal women who received hysterectomy with concurrent bilateral ovariectomy on benign uterine indications were recruited.Climacteric symptoms before and after operation were accessed by a questionaire including modified Kupperman Index.Comparison was made after grouping the patients into early menopause group,whose menopausal period was no more than 5 years,and late menopause group,whose menopausal period was more than 5 years. Results Among a total of 95 individuals,8 had normal,46 had mild,34 had moderatc,and the other 7 had severe Kupperman Index scores before operation,while 5 had normal,28 had mild,48 had moderate,and the other 14 had severe Kupperman Index scores after operation,with more moderate and severe climacteric symptoms after operation than before operation(P<0.05).Women of early menopause group had higher total Kupperman Index scores and symptom scores of sweating,insomnia,depression,fatigue and headache than those of late menopause group before operation(P<0.05).Women of early menopause group had significantly higher Kupperman Index scores after operation than before operation(23.93±7.53 vs 17.63±8.07,P<0.05).However,there was no significant difference in total Kupperman Index scores in women of late menopause group before and after operation. Conclusion Bilateral ovariectomy may affect the climacteric symptoms in post-menopausal women,especially in early menopausal period.

Objective:To determine levels of insulin and glucose of maternal serum (MS),umbilical venous serum (UVS) and umbilical artery serum (UAS) in normal term pregnancy and intrauterine growth retardation(IUGR).Methods:One hundred and seven cases of normal gestational weeks on induction of labors and spontaneous deliveries and 32 cases of pregnancies complicated with IUGR.Levels of insulin were measured with sensitive radioimmunoassay and levels of glucose were measured by the glucose oxidase-peroxidase method.Results:Level of insulin of maternal serum was not significantly different before 28 gastational weeks and peaked on 28 th gastational week,then it decreased with gestational weeks and peaked again at last term.Levels of insulin increased in UVS and UAS.Levels of glucose in MS,umbilical venous serum and umbilical artery serum were not significantly different.Level of insulin and glucose of MS in IUGR had no change,but it was significantly different in IUGR of UVS and UAS (P<0.01).Conclusion:Our study suggested a decrease of insulin and glucose in UVS and UAS with IUGR.

Objective To investigate the value of transcatheter thrombolysis treatment of acute A V internal fistula thrombogenesis in hemodialysis patients. Methods The acute A V fistula thrombogenesis in 32 hemodialysis patients with chronic renal failure were treated with transcatheter pulse spray pharmacomechnical thrombolysis (PSPMT). Results Acute A V fistula thrombogenesis was verified in all 32 patients by angiography and treated with transcatheter PSPMT. The immediate clinical success rate of thrombolysis was achieved in 97% except for one case. The A V fistulas were proved to reopen by post treatment angiography. Recurrent thrombosis was found in 4 cases, reopenning with transcatheter PSPMT was achieved in 2 of them and the rest 2 cases were undergone PTA because of localized vascular stenosis. All the 32 A V fistulae, were reopened after treatment without serious complications such as hemorrhage, pulmonary embolism and others.Conclusions Transcatheter PSPMT is a safe, effective and microinvasive treatment for acute A V fistula thrombolysis with higher immediate reopenning rate. Transcatheter PSPMT combined with PTA and intravascular stent grafting can improve long term patency rate.

Objective To investigate the effects of ethinylestradiol and cyproterone acetate tablets(Diane-35)on endocrine metabolism in non-obese women with polycystic ovary syndrome(PCOS). Methods Fifty-three non-obese patients with PCOS were assigned to the 6-month treatment with Diane-35.Body mass index(BMI),waist to hip ratio(WHR),F-G score and acne score were recorded before treatment and at the end of the third and sixth cycle after treatment.Serum total testosterone,follicle stimulating hormone(FSH),luteinizing hormone(LH),LH/FSH,fast plasma glucose,fast insulin and insulin resistance index(HOMA-IR)were obtained at early follicular phase and at the end of the third and sixth month.Results There was no significant change in BMI and WHR after treatment.Compared with those before treatment.F-G score,acne score,serum total testosterone,LH and LH/FSH were significantly decreased at two time points after treatment (P<0.05).BMI and HOMA-IR in patients with insulin resistance were significantly higher at the end of the sixth cycle after treatment than those before treatment(P<0.05). Conclusion Diane-35 can improve hyperandrogenism in non-obese patients with PCOS.However,Diane-35 may aggravate insulin resistance in those with insulin resistance.

Aim: To provide the foundation for reasonable utilization by analyzing the essential oils of Sabina pingii var. wilsonii.. Methods: The essential oils were extracted using steam distillation and separated with GC capillary column. The components were quantitatively determined with normalization method, and were preliminarily identi-fied by GC-MS. Results: 79 Components were identified, which took up 93. 78% of the essential oils. Conclusion: The main components of essential oils were a-terpineol( 16. 70%); α-fenchene( 14. 98%); 2,6,10-dodecatrien-1-ol, 3,7, 11-trimethyl-( 6.49%); 1, 4-cyclohexadiene, 1-methyl-4-[1-methylethyl]-( 4. 74%); kaura-5, 16-dien-18 [orl9]-ol(3. 62%); naphthalenemethanol, 1, 2, 3, 4, 4a, 5, 6, 7-octahydro-α, α, 4a, 8-tetramethyl-, [2R-cis]-(3. 04%); [ + ]-4-carene ( 2. 81%); D-limonene ( 2. 71%); β-myrcene ( 2. 59%); cedrol (2.40%); a-pinene (2. 36%); 7-isopropyl-1, 1, 4a-trimethyl-1 ,2,3,4,4a, 9,10,10a-octahydrophenanthrene(2. 32%).

Objective: To study the effects of pharmaco-serum from rabbits administrated intragastrically with Fuzheng Jiedu decoction(FJD) on injured human bronchial epithelial(16HBE) cells exposed to nickel sulfate(NiSO4).Methods: Cultured 16HBE cells were treated with both NiSO4 and different doses of FJD pharmaco-serum in vitro.The detections of cell activities and viabilities were carried out.Meanwhile,activities of glutathione peroxidase(GSH-Px) and superoxide dismutase(SOD) as well as maleic dialdehyde(MDA) contents were measured.Results: FJD pharmaco-serum could decrease mortalities and increase viabilities of 16HBE cells exposed to NiSO4.In cells co-treated with NiSO4 and FJD pharmaco-serum,the content of MDA was decreased,while GSH-Px and SOD activities were increased at the same time.High dose of FJD pharmaco-serum had the most dramatic effect.Conclusion: This study suggested that FJD could antagonize NiSO4-induced toxicity,which may be involved in its antioxidant function.

Objective To investigate the effects of surgery-induced menopause on neuropsychological symptoms in women with perimenopause. Methods Sixty-eight women with perimenopause who underwent bilateral oophorectomy for benign indications were evaluated by the modified Kupperman index on the perimenopause syndrome pre-and post-surgery,including the score in neuropsychological symptoms.Patients were further requested to remake a decision on the acceptance of surgery,and were divided into "accept the surgery" group(n=30) and "postpone the surgery" group(n=38).The neuropsychological symptoms were reevaluated and comparison was made between these two groups. Results The prevalence of perimenopause syndrome pre-surgery was 67.65%(22/68),and that of moderate and severe symptoms was 30.88%.The prevalence of perimenopause syndrome post-surery(97.06%)(66/68)was significantly increased,as well as that of moderate and severe symptoms(70.59%)(P
