Perimenopausal syndrome is a common uncomfortable symptom in women during the perimenopausal period, with a high incidence, a long duration, and adverse effects on physical and psychological, patients bear a heavy burden of symptoms, and increase the risk of adverse events in the elderly stage, increase the social medical burden. With the development of sports rehabilitation research, more and more attention has been paid to the effect of exercise on human health. This paper reviews the studies on exercise rehabilitation in women with perimenopausal syndrome, including exercise forms, exercise intensity, exercise time and exercise effect, in order to provide basis for the relevant research and practice.

Objective To explore the microsurgery methods in patients with early intracranial aneurysm rupture. Methods Sixty-seven patients with early intracranial aneurysm rupture received the emergency microsurgery after releasing cerebrospinal fluid from improved Paine point via pterion craniotomy. Thirty-nine patients received surgery within 1 d after intracranial aneurysm rupture, and the other 28 patients were within 1-3 d. Results The therapeutic effect was evaluated by Glasgow outcome score (GOS) at discharge. Among the 45 patients with Hunt-Hess Ⅰ-Ⅲ grade, cure was in 41 cases, improved in 4 cases. Among the 22 patients with Hunt-HessⅣ-Ⅴgrade, cure was in 6 cases, improved in 6 cases, moderate disability in 4 cases, severe disability in 1 case, and death was in 5 cases. Conclusions The microsurgery of clipping aneurysm directly via pterion approach is still by far the most reliable treatment. And releasing cerebrospinal fluid from improved Paine points can effectively reduce the acute brain swelling of early operation, which will make it an effective adjuvant therapy to emergency microsurgery of clipping aneurysm.

To investigate the expressions of placental growth factor (PLGF) in placenta with hypertensive disorders of pregnancy (HDP), 45 women with HDP and 20 normally pregnant women were studied. Among 45 women with HDP, there were 23 cases of severe preeclampsia and one case of eclampsia. The location and level of PLGF proteins was determined by immunohistochemistry and Western blot. The expression of PLGF mRNA in placenta was assessed by reverse transcriptional-polymerase chain reaction (RT-PCR). The results showed that: (1) The distribution of PLGF in placenta with HDP was similar to normal one, which was mainly in the cytoplasm of villous syncytiotrophoblast and villous stroma; (2) The expression of PLGF protein was significantly decreased in placentas with mild and severe preeclampsia compared to the normal ones (0.3 +/- 0.4 vs 0.6 +/- 0.4, 0.2 +/- 0.5 vs 0.6 +/- 0.4, P < 0.01). There were no differences between the gestational hypertension placenta and normal one (0.5 +/- 0.6 vs 0.6 +/- 0.4, P > 0.05); (3) The transcription levels of the PLGF mRNA in placentas with preeclampsia were significantly lower than in normal groups (3.33 +/- 0.39 vs 4.87 +/- 0.60, 1.97 +/- 0.29 vs 4.87 +/- 0.60, P < 0.01), and no differences were found between the gestational hypertension placenta and normal groups. These findings suggest that the abnormal expression of PLGF in placentas is related to the pathogenesis of HDP.

OBJECTIVE To optimize the parameters of passive cutaneous anaphylaxis(PCA)in rats immunized by ovalbumin(OVA). METHODS 1-2 month-old Sprague-Dawley rats were immu?nized by ip injection of OVA(0.2,1.0 and 5.0 mg per rat)mixed with complete Freund′s adjuvant once every other day 3 times. Serum was collected on the 12th-16th days after final immunization. Then the rats were intracutaneously injected with sensitized serum and then stimulated by iv injection of the same dose of OVA mixed with Evans blue after a latent period of 0.5,1.5,3,6,12,24,36,48 and 60 h. Finally,the diameters of blue spots in the skin were measured at stimulation. RESULTS Serum total-IgE(T-IgE)and OVA-specific IgE(sIgE)levels increased significantly and reached the peak on the 3rd-7th days and 12th-16th days after final immunization,respectively. There was no correlation between the serum T-IgE level and OVA-sIgE level when the rats were immunized with OVA at OVA 0.2-5.0 mg per rat. The rats experienced PCA after injection of OVA 1.0 and 5.0 mg per rat. Diameters of blue spots in the skin reached the maximum value after rats were sensitized for 0.5-3 h. Moreover,the shape,color and size of blue spots were better 30-60 min after stimulation. CONCLUSION Optimized PCA is as follows:1-2 month-old rats are immunized on the 1st,3rd and 5th days by ip injection of OVA 1.0-5.0 mg. The immunizing serum is collected at 12-16 d after final immunization. The rats are stimulated by OVA and Evans blue after a latent period of 0.5-3 h. Diameters of blue spots in rats′ skin are then measured 30-60 min after stimulation.

Objective:To compare the clinical efficacy of drug coated balloon (DCB) vs. plain old balloon (POB) on in-stent restenosis (ISR) of femoropopliteal artery occlusive disease of the lower limb. Methods:The clinical data of 91 ISR patients admitted at Shanxi Bethune Hospital from Jul 2016 to Dec 2017 were retrospectively analyzed. The primary patency rates were compared.Results:There were 43 patients treated with drug coated balloons and 48 patients treated with plain old balloons. The surgical procedure was successful in all cases, and the symptoms of lower limb ischemia were significantly improved after surgical procedure. The primary patency rate of patients who were treated by drug coated balloons was significantly higher than by plain old balloons at 12 months after surgery (83.7% vs. 62.5%, P<0.05). Conclusion:The use of drug coated balloons could acquire more satisfactory short-term clinical efficacy for ISR patients of femoropopliteal artery occlusive disease.

Objective:The aim of this study was to explore the relationship between nurses ′ work environment and menopausal symptoms. Methods:A multicenter, cross-sectional study was performed in Beijing, China, distributed to 2 194 registered nurses at 37 hospitals. Using a self-designed questionnaire included individual personal details, and the hospital working environment. Menopausal symptoms were evaluated using a modified Kupperman index (KMI) scoring system.Results:The average natural age at menopause stag was 47.64 years with 63.91% (1 328/2 078) nurses without menopausal symptoms. Logistic analysis showed that menopausal symptoms were co-dependently influenced by the following: to frequently contact with patient bodily fluids during your work ( P=0.037); be intimidated in your work ( P<0.01); to often or occasionally face death at work ( P=0.013 and P=0.002). Nurses suffered more stressful environment with high prevalence of menopausal symptoms. Conclusions:The mid-age nurses with menopausal symptoms were related with work environment. Managers should pay more attention to this problem.

Objective:To evaluate the clinical efficacy and safety of cytoreductive surgery plus hyperthermic intraperitoneal chemotherapy (CRS+HIPEC) for patients with advanced ovarian cancer as the first-line surgical treatment.Methods:The ovarian cancer patients with completed clinical data diagnosed as stage Ⅲ C-Ⅳ according to Federation International of Gynecology and Obstetrics (FIGO) who underwent CRS+HIPEC as the first-line treatment from December 2007 to November 2019 in Beijing Shijitan Hospital were retrospectively analyzed. Survival status was analyzed by using Kaplan-Meier method, and prognostic factors were analyzed by using Cox multivariate regression model. The primary endpoints were median overall survival (mOS) time and median progress-free survival (mPFS) time, and the secondary endpoint was safety in perioperative period. Results:Of 100 patients with advanced ovarian cancer, the median follow-up time was 18.4 months, and 75 (75.0%) patients were alive and 25 (25.0%) patients died, of which the mOS time was 87.6 months (95% CI 72.1-103.1 months), and 1-, 2-, 3-, 4- and 5-year survival rate was 94.1%, 77.2%, 68.2%,64.2% and 64.2%, respectively. Univariate analysis showed that the patients with age≤58 years old ( P = 0.023), Karnofsky≥80 scores ( P = 0.026), ascites ≤1 000 ml ( P = 0.041), peritoneal carcinomatosis index (PCI) score <19 ( P = 0.044) and completeness of cytoreduction (CC) score 0-1 ( P = 0.001) had better prognosis. Multivariate analysis showed that CC score 0-1 was independent prognostic factor, the mortality risk of resectable patients with CC score 2-3 was 3.2 times higher than that in patients with CC score 0-1 ( HR = 3.2, 95% CI 1.4-7.6, P = 0.008), and mPFS time was 23.3 months (95% CI 0-50.7 months) for patients with CC score 0-1. Grade Ⅲ-Ⅳ adverse event rate during perioperative period and mortality rate was 4.0% (4/100) and 2.0% (2/100), respectively. Conclusion:CRS+HIPEC could improve the survival of advanced ovarian cancer patients with good safety.

There were no differences between the gestational hypertension placenta and normal one (0.5±0.6 vs 0.6±0.4, P＞0. 05); (3) The transcription levels of the PLGF mRNA in placentas with preeclampsia were significantly lower than in normal groups (3.33±0.39 vs4.87±0.60, 1.97±0.29 vs 4.87±0. 60, P＜0.01), and no differences were found between the gestational hypertension placenta and normal groups. These findings suggest that the abnormal expression of PLGF in placentas is related to the pathogenesis of HDP.

Ischemic stroke is the main cause of death and disability in adults, and its incidence is increasing year by year. Obstructive sleep apnea (OSA) is the most common type of sleep-disordered breathing, which can increase the risk of ischemic stroke and affect the outcomes of patients. There is an increasing amount of research on the relationship between OSA and ischemic stroke. This article reviews the bidirectional relationship between OSA and ischemic stroke, the mechanism of OSA causing ischemic stroke, and the diagnosis and treatment of OSA in patients with ischemic stroke.
