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

AIM: To study a novel gene that probably related with liver regeneration, which was found by representational difference analysis(RDA). METHODS: cDNA sequence, tissue distribution and functions of the novel gene were studied by slot blot, Northern blot, RT-PCR, cDNA library screening and sequence analyzing. RESULTS: Two full-length clones were isolated from cDNA library of rat fetal livers and the sequence analysis identified that the positive cDNA encoded 76 amino acids only; Using the cDNA as a probe, the novel gene showed a specific liver distribution, a moment increasing expression in one hour after partial hepatectomy (PH) and high expression in fetal liver or liver tumor by Northern blot; EGF quickly induced its high expression in primary culture rat hepatocytes(FCS free).CONCLUSION: These results show that the novel gene is an early phase response gene that is closely related to a liver regeneration adjustment. It may encode peptide or has longer sequence at N tip.

Objective To study the factors influenceing patients' family members to make own relative fac-tors patients' families making decision on refusal of cardiopulmonary resuscitation (CPR) to the critical patients. Method Data were registered based on Utstein Style of 522 patients aged over 15 years, who subjected to in-hos-pital cardiac arrest(CA) in Department of Emergency of The First Affiliated Hospital of Wenzhou Medical College from January 2005 to December 2008. A total of 157 patients' family made refusal decision among the 522 pa-tients, who belonged to the refusal group, and others belonged to the attempt resuscitation group. The associated factors included age, sex, marriage, household register, cause of CA, underlying diseases, capability of activity before CA, life supported with mechanical ventilation, and administration of pressor agents. The refusal decisions were evaluated by using univariate Logistical regression analysis, and then the statistical significant variables were analyzed by using muhivanate Logistical regression analysis. Results Age, household register, cause of CA(car-diac or traumatic),stroke, sudden death, cancer, capability of activity before CA, life supported with mechanical ventilation,and administration of pressor agents were the important factors of making refusal decision (P < 0.01), but sexes or marriage was insignificant related to the refusal decision (P > 0. O5). The independent risk factors re-lated to refusal decision were age (P = 0.034),cancer (P = 0.006),stroke (P = 0.003), and life supported with mechanical ventilation (P = 0.000) in multivariate Logistical regression analysis, but the protective factors were sudden death (P =0.000),cardiac CA (P =0.020) and traumatic CA(P =0.000). Conclusions Age over 60 years, cancer, stroke, and life suppoted with assisted ventilation before CA were factors associated with re-fusal decision making, yet sudden death, cardiac CA and traumatic CA were factors of accepting CPR.

Objective To compare the difference of implanted cooled-shaft with 915 MHz and 2450 MHz microwave in ablation area and the characteristics of temperature field in porcine livers in vivo. Methods Ablations were performed with 915 MHz and 2450 MHz, and were divided into two groups accordingly. The microwave antenna was inserted into porcine liver in vivo and the thermal needles were placed in parallel 5 mm, 10 mm, 15 mm, 20 mm, away from the antenna slit. The temperature data were collected with computer when the microwave ablation was started with the same energy of 60 W 600 s. After ablations, sizes of the ablation zones and the temperature curves were compared between the two groups. Results Compared with 2540 MHz microwave, 915 MHz microwave had larger coagulation length and width, faster temperature ascending rate and higher temperature in corresponding points. Conclusion In porcine livers in vivo, compared with 2450 MHz microwave, larger coagulation zone and faster temperature ascending rate can be obtained with 915 MHz microwave.

Background and Objectives: Stroke is the most common neurological disease in China and regulation of lipid levels is important for secondary prevention. This study aimed to investigate the practice of lipid lowering agents immediately after and one month following ischemic stroke in China, and to determine the factors affecting the practice. Methods: A total of 857 patients with acute ischemic stroke were enrolled from 11 hospitals in the Qingdao area, Northern China. Data pertaining to the patients’ demographic, clinical data, and treatment before and after the stroke were recorded. Univariate and multivariate logistic regression analyses were used to determine the factors associated with the treatment at two time points: at the acute stage and at one month follow-up. Results: The frequency of lipid lowering therapy was 50.3% (431/857) at acute stage and 41.5% (306/738) at one month. Lipid lowering therapy at acute stage was independently and positively associated with a history of hyperlipidemia((P=0.002, OR (95%CI): 3.784 (1.610-8.898)) and excess alcohol consumption (P=0.005, OR (95%CI): 1.928 (1.214-3.062)), partial anterior circulation infarct classifi cation (P=0.000, OR (95%CI): 1.974 (1.370-2.767)), and low-density lipoprotein levels ((P=0.000, OR (95%CI): 1.426 (1.170-1.739)). Lipid lowering therapy at one month follow-up was independently and positively associated with lipid lowering therapy at acute stage ((P=0.000, OR (95%CI): 18.275 (11.476- 29.101)), and negatively with the Modifi ed Rankin Scale ≥4 at follow-up ((P=0.030, OR (95%CI): 0.568 (0.341-0.948)). Conclusions: Lipid lowering therapy was found to be used in about half of patients during acute and early secondary prevention of ischemic stroke in the Qingdao area of Northern China. There should be more education efforts to the health care professionals and public to increase its use.

ObjectiveTo assess the safety and efficacy of contrast-enhanced ultrasound (CEUS)-guided percutaneous microwave ablation (MWA) treatment of renal carcinomas.MethodsFifteen patients with 17 renal tumors were retrospectively analyze. The patients’ ages were in the range of 46-80 years (65.2±9.4 years), the tumor diameters were in the range of 1.1-3.9 cm (2.3±0.7 cm) and biopsy pathological results were renal cell carcinoma. All of the tumors were inconspicuous on conventional ultrasound, while conspicuous on contrast enhanced-computed tomography (CT) or magnetic resonance imaging (MRI). Seventeen tumors were ablated under the guidance of CEUS.ResultsAll tumors were successfully visualized on CEUS and MWA was performed under CEUS guidance. The durations of energy application for each tumor were in the range of 5-11 min (mean± SD 7.3±2.2 min). The mean session of CEUS-guided MWA for each tumor was 1.1±0.3. All patients were followed up for 3-49 months (median, 17 months) to observe the therapeutic effects and complications. There was no local tumor progress and major complication. ConclusionCEUS-guided PMWA is a safety, efficient and feasible therapy for patients with RCC which is inconspicuous on conventional US.
