Objective To observe the effect of acute hypervolemic hemodilution(AHH) combined with nicardipine controlled hypotension on hemodynamics changes in revision operation of total hip replacement.Methods Forty patients were divided into two groups according to the sequence of the surgery(odd number came into group A,even number came into group B,20 in each group).In group A,AHH was carried out with nicardipine controlled hypotension;group B was control group.AHH was carried out in both groups before anesthesia induction.6%voluven was transfused in group A at 15 mL?kg-1 and 30 mL?min-1 and nicardipine was transfused at 0.3-0.5 mL?kg-1?h-1 with MAP altering between 60 and 65 mmHg;Same quantity of physiological saline was transfused in group B.HR,MAP,CVP,Hb,Hct and Plt were recorded and observed at preoperation,1 h after AHH and 24 h after the operation.Results In group A after AHH with nicardipine controlled hypotension,MAP was obviously lower than pre-operation(P

Objective To explore the incidence and imageological features of patients with the hippocampal sclerosis-associated medial temporal lobe epilepsy. Methods Seventy-eight patients with the medial temporal lobe epi?lepsy were recruited from our hospital during February 2012 to December 2013. Magnetic resonance imaging (MRI) and resonance spectroscopy (MRS) analysis were conducted in patients with with the hippocampal sclerosis-associated medial temporal lobe epilepsy, patients with epilepsy without the medial temporal lobe diseases and healthy controls. Results The incidence of hippocampal sclerosis was 58.97%among patients with medial temporal lobe epilepsy which were significantly higher compared with either healthy control group or patients with epilepsy without the medial tempo?ral lobe diseases. The average hippocampal volume of the medial temporal lobe epilepsy group(2305.68±814.61 mm3、2456.71±743. 60 mm3)was significantly smaller compared with either healthy controls or patients with epilepsy without the medial temporal lobe diseases. MRI revealed increased T2WI signal and hippocampal atrophy in 74.55%of patients with hippocampal sclerosis-associated medial temporal lobe epilepsy. Sclerosis was detected on the left side (52.17%) and bilateral hippocampus (19.57%). MRS showed that NAA/(Cr ± Cho) significantly reduced (0.58± 0.19) in the hip?pocampal sclerosis. Conclusions Hippocampal sclerosis may be the main imaging features of the medial temporal lobe epilepsy which are characterized by the hippocampal atrophy and high T2WI signal.

Objective To investigate the epidemiological features of back pain, spondyloarthritis (SPA) and ankylosing spondylitis (AS) in Beijing Shougang district. Methods Set up Chinese version of questionnaire about incidence of spondyloarthro-pathy. Employees and retired ones were drawn out from subfactory units by non-randomized sampling. 15 357 subjects were investigated, of which 12 125 questionnaires were taken. Suspected cases were then screened with sacroiliac joint X ray and HLA-B27 testing. 2009 assessment in ankylosing spondylitis (ASAS) criteria were used for diagnosing SpA. Results Back pain is common with total incidence of 42.7%, and the most common pattern is mechanical pain. The incidence of SpA is 0.58% and that of AS is 0.36%, while only 28.9% AS patients had been diagnosed before and received treatment. Conclusion The AS incidence in Shougang district is similar with the epidemiological data got from other districts of China. And knowledge of SpA and AS is needed in China.

Objective To explore the characteristics of vaginal microecology and vaginitis distribution of female patients in Xi'an,so as to provide reliable reference for clinical treatment.Methods A total of 102 124 women in Shaanxi Provincial People's Hospital from January 2018 to August 2023 were selected as the research objects.Vaginal secretions were collected from patients,and the vaginal microecology was detected and analyzed.Results Among 102 124 female patients,99.87%had vaginal microecological imbalance.The main disease types were vulvovaginal candidiasis(VVC),accounting for 16.03%,bacterial vaginitis(BV),accounting for 9.61%and trichomonal vaginitis(TV),accounting for 1.34%.Statistical analysis showed that the age of VVC,BV and TV patients was mainly 21～30 years old.The prevalence of VVC and BV in summer and autumn was higher than that in other seasons,while the prevalence of TV was relatively high in summer.In addition,there were 27 552 cases of simple vaginitis(26.98%)and 1 443 cases of mixed vaginitis(1.41%)in 101 995 female patients with vaginal microecology imbalance.In patients with mixed vaginitis,the BV+VVC combination accounted for the vast majority(79.00%),and the age group was mainly between 21 and 40 years old.Among the 28 995 patients with vaginitis,4 308 patients(14.86%)had recurrence,and the recurrence rate of simple vaginitis(11.44%,3 152/27 552)was much lower than that of mixed vaginitis(80.11%,1 156/1 443).Conclusion The main type of female simple vaginitis in Xi'an is VVC,which has a high prevalence in summer and autumn.The main type of mixed vaginitis is BV+VVC,Compared with simple vaginitis,patients with mixed infection are more likely to relapse.
