OBJECTIVE:To study the effects of mifepristone on related indexes of patients with myomectomy. METHODS:The information of 100 patients with uterine fibroids were analyzed retrospectively,and they were divided into observation group and control group according to therapy method,with 50 cases in each group. Control group only received myomectomy. Observa-tion group was given Mifepristone tablets 10 mg orally,qd,for consecutive 3 months,and then received myomectomy within 2 d after drug withdrawal;they were given Mifepristone tablets 10 mg/d orally after surgery,for consecutive 3 months. The 2 groups were followed up for 6 months. The maximual volume of uterine fibroids and the volume of uterus were compared between 2 groups as well as related operation indicator,levels of serun reproductive hormones,sex hormones of uterine myoma tissure and re-lated growth factors of uterus myomas. The recurrence and occurrence of ADR was recorded during treatment. RESULTS:Before surgery,the maximual volume of uterine fibroids and the volume of uterus in observation group were significantly lower than control group,with statistical significance(P<0.05). The operation time,vaginal bleeding time and hospital stay of observation group were significantly shorter than those of control group,the intraoperative blood loss and the recurrence rate were significantly lower than those of control group,with statistical significance (P<0.05). Six months after surgery,ER,PR,EGFR,TGF-β1R and IGF-1R of uterus myomas in observation group were significantly lower than those of control group,with statistical significance (P<0.05). There was no statistical significance in the levels of FSH、E2 and P level of uterus myomas between 2 groups in first di-agnosis and 6 months after surgery(P>0.05). No obvious ADR was found in 2 groups during treatment. CONCLUSIONS:Mife-pristone helps to reduce operative time,intraoperative blood loss,vaginal bleeding time and hospital stay of patients with myomecto-my,and may be related to the regulation of ER and PR levels and related growth factor receptors.

Objective To explore the risk factors of newly emerging advanced schistosomiasis patients in endemic areas.Methods The study areas were selected in two counties of Dongting Lake regions and a 1 :2 match case-control study was designed.Sixty schistosomiasis patients,who newly evolved into advanced schistosomiasis from 2006 to 2007,were selected into the case group,and 120 cases with chronic schistosomiasis into the control group.Questionnaires including potential risk factors of advanced schistosomiasis were designed and the information was collected based on face to face interviews.SPSS 12.0 was used to analyze the simple factors and multi ones (logistic regression) attributable to the development of advanced schistosomiasis.Results The history of hepatitis B (OR = 10.729),models of water contact (OR = 3.919) ,yearly exposure days to the infested water (OR = 5.457) and times of chemotherapy in the nearly 10 years(OR = 1.578) were the risk factors of development of advanced schistosomiasis.The times of examinations with positive schistosome eggs were protective factors.No association was found between yearly income,education degree,times of checking for schistosomiasis,times of examination with sera positive results and the emergence of advanced schistosomiasis.Conclusion The high frequency of exposure to the infested water,repeated infections,incomplete diagnosis and treatment are the risk factors of advanced schistosomiasis.The concurrent infection with hepatitis B is associated with the acceleration of development of advanced schistosomiasis.

Objective To analyze the schistosomiasis epidemic of 4 national pilots in Dongting Lake regions during 5 years period, and provide references for control strategy and policy making. Methods Four longitudinal monitoring pilots were set up in Dongting Lake regions from 2000 to 2004, and the field work in pilots was carried out based on “National Scheme on Schistosomiasis Epidemic Monitoring”. Results During the monitoring period, the infection rate of Schistosoma japonicum kept at 4% in Dongjia, 5% in Xinshang and over 12% in Quanxing, but in Changjiang, the rate was 8.92% in the first year of monitoring period, and stayed at 4% in the next 4 years. For all pilots, 20-49 age group had the highest infection rate, with the rate in male being higher than that in female and centering on the fishermen, farmers and students in occupation. There was the occurrence of acute and new advanced cases. The infection rate in domestic animals was fluctuated at 20%. There was extensive distribution of infected snails on marshlands outside embankments. Conclusion Schistosomiasis is seriously endemic in Dongting Lake regions, and intensive control measures are necessary.

A new UPLC method was developed for the simultaneous determination of eleven characteristic flavonoid glycosides in Ginkgo biloba leaves. The natural occurrence of flavonoid glycosides in Ginkgo biloba leaves within one vegetative season was investigated for the first time. The analysis was performed on an Agilent ZORBAX Eclipse Plus C18 column (50 mm x 4.6 mm, 1.8 microm), the mobile phase A was acetonitrile, the mobile phase B was 0.4% phosphate aqueous solution in a gradient elution at a flow rate of 0.6 mL x min(-1), the detection was carried out at 360 nm. The result showed that eleven flavonoid glycosides had good linearity with good average recovery, separately. The method was proved to be accurate, rapid and good reproducible for the quality evaluation of Ginkgo biloba leaves, and provide an easy and rapid means for the quantitative analysis of flavonoid glycosides and their content fluctuation with seasons.

Meningoencephalitis caused by the human herpes virus 6 is common in acquired immune deficiency syndrome patients or in patients after organ transplantation, rarely in immunocompetent adults. The clinical manifestations include headache, drowsinesss, coma, epileptic attack, psychiatric symptom and focal neurological signs. Antiviral therapy is effective, however the prognosis should be poor if the treatment is not timely. The clinical data of one case of meningoencephalitis caused by the human herpes virus 6 in Tianjin Haihe Hospital in October 2019 were analyzed. Meningoencephalitis caused by the human herpes virus 6 can be recurrent. The clinical manifestations are nonspecific and the diagnosis is difficult. The next generation sequencing of cerebrospinal fluid is a powerful method to identify pathogens.

Objective Moderate autophagy helps improve the viability of neurocytes.This study aims to investigate the effect of SP600125 on the autophagy and loss of nerve cells in the hippocampus in rats with subarachnoid hemorrhage (SHA).Methods Forty healthy male SD rats were equally randomized into a sham operation, an DMSO group, an SAH model, and an SP600125 group.The SAH model was established by vascular puncture and the rats of the SP600125 group were injected with 10 μL of SP600125 (3 μg/μL) into the lateral cerebral ventricle at 30 minutes before modeling.Sham group and SAH group were injected with equal volume of normal saline, DMSO group was injected with the same amount of DMSO.The animals were sacrificed at 24 hours after modeling for observation of the changes in the morphology and the number of neurons in the hippocampus by HE staining and qualitative and quantitative determination of the expressions of the p-JNK protein and the autophagy markers beclin-1 and LC3-II by immunohistochemistry and Western blot.Results Compared with the sham operation group, the neurons exhibited a disordered arrangement and the cells were polygonal and decreased in number in the hippocampus of the SAH models, while milder neuronal injury and more cells were observed in the rats of the SP600125 group than in the SAH models.The mean optical density values of Beclin-1, LC3-II and p-JNK in the hippocampus were significantly higher in the SAH models (14.66±4.40, 12.62±3.46, and 12.82±3.68) and DMSO (13.85±3.85、11.59±4.52、13.03±3.53), and the SP600125 group (9.86±3.14, 6.78±2.56, and 5.60±2.42) than in the sham operation group (1.56±0.28, 1.60±0.30, and 1.58±0.32) (P<0.05), but markedly lower in the SP600125 than in the SAH model group (P<0.05).The expressions of Beclin-1, LC3-II and p-JNK were remarkably increased in the SAH models (0.474±0.122, 0.668±0.130, and 0.496±0.124) and DMSO (0.432±0.102、0.628±0.113、0.416±0.094) and the SP600125 group (0.264±0.106, 0.332±0.113, and 0.219±0.104) than in the sham operation group (1.56±0.28, 1.60±0.30, and 1.58±0.32) (P<0.05), but significantly decreased in the SP600125 group as compared with the SAH models (P<0.05).Conclusion SP600125 has a protective effect on the neurocytes in the hippocampus of SAH rats, which may be associated with SP600125 moderately activating neuronal autophagy by inhibiting the activity of the JNK signaling pathway.

Objective To analysis the activity of transcriptional factors in endometrial cancer cell lines with different estrogen receptor subtypes. Methods The mRNA levels of estrogen receptor (ER) was detected by quantitative RT-PCR , and the activity of transcriptional factors was also analysed by 345-channel protein/DNA array in RL-952 ( the expression status of ERα and ERβ both positive), HEC-1A [ERα(±),while ERβ negative] and HEC-1B (ERα and ERβ both negative). The transcription factors of NFkBp65 and p38MAPK with different activity were tested by enzyme-linked immunosorbent assay(ELISA) to confirm the results of protein/DNA array. Results The mRNA levels of ERα in RL-952, HEC-1A and HEC-1B were (6780±282 ), ( 684±84 ) and ( 168±38 ) eopy/ng, respectively. Among 345 candidate transcriptional factors, there were 28 factors associated with ER status. Compared with RL-952 cells, 13 transcriptional activity factors were concomitandy up-regulation, while 15 concomitantly down-regulation in HEC-1A and HEC-1B cells. Transcriptional activities of TrF (1)-1, NRF-1, TCE were significantly correlated with the high-expression status of ERα mRNA ( r =0.523, P=0.037 ), while RFX123 and Ikaros were signitleanfly correlated with the low-expression status of ERα mRNA ( r=-0.312, P=0.041 ). Conclusion Transcriptional factors of TTF(1)-1, NBF-1, TCE may be associated with ER-mediated signal pathway, while RFX123 and Ikaros may be associated with non ER-mediatecl signal pathway in endometrial cancer.

Objective To investigate the correlation of serum levels of retinol binding protein 4 (RBP4) and andomen?tin-1 with ischemic stroke and carotid artery stenosis. Methods Healthy adult (n=50) were selected as the control group while ischemic stroke patients with different degrees of carotid artery stenosis (n=143) were enrolled as the disease group. According to the ultrasonic Doppler performance, these ischemic stroke patients were divided into three groups:mild steno?sis group (carotid artery stenosis was normal or less than 50%, n=67), moderate stenosis group (carotid artery stenosis was 50%to 70%, n=45), severe stenosis group (carotid artery stenosis was 70%to total occlusion, n=31). BMI index, hyperten?sion, total cholesterol (TC), triglyceride (TG), high density lipoprotein (HDL), low density lipoprotein (LDL) and fasting blood glucose (FPG) were detected by Automatic biochemical analyzer and serum levels of RBP4 and omentin-1 were measured by ELISA. Results Hypertensive population in carotid artery stenosis group was larger than that in control group (P<0.05). Serum TC, TG, LDL, FPG and RBP4 levels were significantly higher while omentin-1 level decreased remarkably in disease group than those in the control group (P<0.05). Logistic regression analysis showed that TC and RBP4 were the risk factors of ischemic stroke with carotid artery stenosis, while omentin-1 was a protective factor. Conclusion RBP4 is a risk factor for ischemic stroke with carotid artery stenosis and omentin-1 is a protective factor.

Objective To observe the influence of nocturnal prolonged hemodialysis (INHD) on patients＇ nutrition status. Methods Thirty-two maintenance hemodialysis patients received INHD (3 times per week and 7.5 hours each session) and thirty-five maintenance hemodialysis patients received conventional hemodialysis (3 times per week and 4 hours each session) as control were observed for 6 months.The nutrition status of these patients on various aspects which concluded physical measurements,laboratory tests,and dietary record at baseline(0month) and exit (6 months) were recorded. Results (1)There were no differences in age,sex,body weight,and primary diseases between two groups.(2)The body weight,triceps skinfold thickness (TSF),and hand grip strength increased at exit point,but no statistical difference compared with the control group.Mid-upper arm circumference (MAC) increased signicantly from (27.1±4.2) to (30.5±6.1) cm (P＜0.05).Compared with the control group (26.9±3.4) cm,there was a significant difference (P＜0.05).(3)Serum phosphate decreased significantly from (0.5±0.5) to (0.1±0.6) μ mol/L (P=0.001) in INHD group.(4)The nutrition status were improved in INHD group evaluated by subjective global assessment (SGA)(P=0.03).(5) Dietary intake was recorded by a 3-day food record.Dietary intake of energy,protein,lipid,calcium,potassium,and phosphate increased in INHD group.None of the differences achieved statistical significance between two groups. Conclusion As compared with conventional hemodialysis,INHD can increase the dietary intake,decrease serum phosphate level,and improve patients nutrition status.
