Objective To explore the effect of eletroacupuncture (EA) on angiogenesis after cerebral ischemia and reperfusion through observing the number of peripheral blood endothelial progenitor cells (EPCs) and the expression of vascular endothelial growth factor (VEGF) in the hippocampus.Methods Among 50 male Sprague-Dawley (SD) rats,10 were randomly selected as a control group (CG).Qi deficiency and blood stasis were induced in the other 40 rats by intragastric administration of dahuang daily for 7 days.A model of focal cerebral ischemia and reperfusion injury was then created by thread-occlusion of the middle cerebral artery,except in 10 rats selected for the sham operation group (SOG) who received the same operation without tightening the thread.The successfully modeled rats were divided into a model group (MG,n =10) and an electroacupuncture group (EAG,n =10).The rats in EAG started acupuncture treatment the next day after modeling,while no treatment was given to those in the other groups.On day 1,3 and 7 after the modeling,the neurological functioning of the 4 groups was assessed using Basso-Beattie-Bresnahan locomotion scoring and the number of EPCs in the peripheral circulation was detected by flow cytometry.On the 8th day,all the rats were decapitated and the VEGF expression was detected immunohistochemically.Results The average BBB locomotion score of the EAG rose significantly from (4.50 ± 1.05) on day 1,to (13.67 ± 1.21) on day 3,and then further to (20.00 ±0.89) by day 7,significantly higher than that of MG at the same time points,but still significantly lower than that of the control group.The average number of EPCs in the peripheral circulation in the MG also increased from (26.83 ± 6.05) on day 1 to (33.67 ± 5.39) on day 3,and decreased to (32.83 ± 5.04) on day 7 after modeling,significantly lower than that of the CG [(45.50 ±9.40),(42.17 ±4.62) and (41.33 ±5.50)],the SOG [(58.00 ±8.05),(59.67±4.84) and (53.83 ±5.38)[and the EAG [(66.17 ±4.36),(127.50 ±73.75) and (55.00 ±35.15)] at each time point.After occlusion,the average expression of VEGF-positive cells in the hippocampus of the EAG [(27.80 ± 2.39)%] was significantly higher than that of the MG,and both were significantly higher than that of the CG.Conclusions Eletroacupuncture can up-regulate VEGF expression and EPCs in the peripheral blood in rats after cerebral ischemia-reperfusion,which can promote angiogenesis and neural functional recovery.

Objective:To investigate the effect of modified transanal approach in the repair of vesicorectal fistula after radical prostatectomy.Methods:From September 2011 to December 2019, 32 cases of vesicorectal fistula after radical prostatectomy were retrospectively analyzed. All patients underwent cystostomy before repair operation. The average diameter of the fistulas was 19 (3-40) mm. There was only one fistula in 24 cases and 8 cases with more than 2 fistulas. The operation was performed in the jack knife position, and the fistula was prepared by resection of the fistula through the anus with bipolar resectoscope. Then bladder wall and rectum wall were separated by the loop and sutured respectively. After operation, the patients were treated with antispasmodic and anti-infective treatment, and the catheter was retained. Cystography and cystoscopy were reexamined 3 months after operation. Catheter was removed in the successful cases, and the failure was repaired again.Results:All operations were completed successfully. The mean operation time was 67(55-125) min, and the median follow-up was 22 (6-30) months. Thirty-one cases (96.8%) were successfully repaired, of which 25 cases were successfully repaired at the first operation, and 6 cases were successfully repaired again (all by transanal route). One case failed to be repaired. He had received external pelvic radiotherapy before operation. After the failure of repair, cystoscopy showed large fistula and stiff surrounding tissue. Then bilateral ureteral skin stoma and cystectomy were performed.Conclusions:Modified transanal approach in the repair of vesicorectal fistula after radical prostatectomy is an effective method. This kind of operation has less trauma, fewer complications and can be operated repeatedly. It is suitable for patients with low position, small fistula and without radiotherapy.

Electronic health record is an important part of medical information research and has been widely used in medical institutions to help medical personnel deal with various medical information. However, due to the lack of standardized nursing language, nurses are often unable to reuse nursing data in electronic health records, which hinders the further development of medical information sharing and electronic health records. The use of standardized nursing language can support efficient and complete nursing documents in electronic health records and meet the requirements of clinical and data interoperability. This paper summarizes the definition and significance of electronic health record and standardized nursing language and the application status of standardized nursing language based on electronic health record, so as to provide scientific reference for the development and improvement of electronic health record in China.

Objective:The characteristics of women with false elevated testosterone were analyze and the literature was reviewed to provide reference for clinical laboratory identification of false elevated testosterone.Methods:The characteristics of three patients with false elevated testosterone in Peking Union Medical College Hospital were analyzed retrospectively, and the results of different detection platforms and methods for the determination of testosterone levels were compared. International and domestic literatures related to false elevation of testosterone and detection methods of testosterone were searched for a comprehensive analysis from PUBMED and CNKI.Results:The levels of testosterone in 3 female patients were elevated by immunoassay and normal by mass spectrometry. They were excluded from the diagnosis of hyperandrogenemia. A total of 38 literatures related to testosterone detection were retrieved, of which 9 case reports of pseudohyperandrogenemia, among which 12 cases of pseudohyperandrogenemia were reported in 2 domestic literatures in 2021. All cases were confirmed by liquid chromatography-tandem mass spectrometry (LC-MS/MS). Previous studies have clearly indicated that the result of routine immunoassay in clinical laboratory for the determination of female testosterone have poor correlation with the results of LC-MS/MS, with varying degrees of deviation.Conclusions:Immunoassay tests for female testosterone is susceptible to interference and lead to elevated false results. It is suggested that clinical laboratories evaluate the detection methods used and establish a identification program, and confirm samples with suspected pseudoelevated testosterone elevation using other immune platforms or LC-MS/MS.

OBJECTIVE:
Diterpenoids with a wide variety of biological activities from Anoectochilus roxburghii, a precious medicinal plant, are important active components. However, due to the lack of genetic information on the metabolic process of diterpenoids in A. roxburghii, the genes involved in the molecular regulation mechanism of diterpenoid metabolism are still unclear. This study revealed the complex metabolic genes for diterpenoids biosynthesis in different organs of A. roxburghii by combining analysis of transcriptomics and metabolomics.
METHODS:
The differences in diterpenoid accumulation in roots, stems and leaves of A. roxburghii were analyzed by metabonomic analysis, and its metabolic gene information was obtained by transcriptome sequencing. Then, the molecular mechanism of differential diterpenoid accumulation in different organs of A. roxburghii was analyzed from the perspective of gene expression patterns.
RESULTS:
A total of 296 terpenoid metabolites were identified in the five terpenoid metabolic pathways in A. roxburghii. There were 38, 34, and 18 diterpenoids with different contents between roots and leaves, between leaves and stems, and between roots and stems, respectively. Twenty-nine metabolic enzyme genes with 883 unigenes in the diterpenoid synthesis process were identified, and the DXS and FDPS in the terpenoid backbone biosynthesis stage and CPA, GA20ox, GA3ox, GA2ox, and MAS in the diterpenoid biosynthesis stage were predicted to be the key metabolic enzymes for the accumulation of diterpenoids. In addition, 14 key transcription factor coding genes were predicted to be involved in the regulation of the diterpenoid biosynthesis. The expression of genes such as GA2ox, MAS, CPA, GA20ox and GA3ox might be activated by some of the 14 transcription factors. The transcription factor NTF-Y and PRE6 were predicted to be the most important transcription factors.
CONCLUSION
This study determined 29 metabolic enzyme genes and predicted 14 transcription factors involved in the molecular regulation mechanism of diterpenoid metabolism in A. roxburghii, which provided a reference for the further study of the molecular regulation mechanism of the accumulation of diterpenoids in different organs of A. roxburghii.

BACKGROUND:
Epilepsy accounts for a significant portion of the global disease burden. However, little is known about the disease burden of epilepsy in China and its provinces.
METHODS:
We assessed the burden of epilepsy in China and its provinces, municipalities, and autonomous regions from 1990 to 2019. Burden was measured as incidence, prevalence, deaths, years lived with disability, years of life lost, and disability-adjusted life years (DALYs), by age, sex, year, and province. We used the Socio-Demographic Index (SDI) to determine the association between the provincial development level and age-standardized DALY rates of epilepsy from 1990 to 2019.
RESULTS:
In 2019, epilepsy caused 1367.51 thousand (95% uncertainty interval [UI]: 979.92-1837.61 thousand) DALYs, and the age-standardized DALY rate was 99.77 (95% UI: 71.33-133.52)/100,000. The age-standardized incidence and prevalence rates for epilepsy in China were 24.65/100,000 and 219.69/100,000, increased by 45.00% (95% UI: 8.03-98.74%) and 35.72% (95% UI: 0.47-86.19%) compared with that in 1990, respectively. From 1990 to 2019, the proportion of DALY caused by epilepsy in the age group under 25 years steadily decreased. The proportion of DALYs caused by epilepsy in people aged 50 years and over increased from 9.45% and 10.22% in 1990 to 29.01% and 32.72% for male and female individuals in 2019, respectively. The highest age-standardized mortality rates were seen in Tibet (4.26 [95% UI: 1.43-5.66]/100,000), Qinghai (1.80 [95% UI: 1.15-2.36]/100,000), and Yunnan (1.30 [95% UI: 0.88-1.62]/100,000), and the lowest mortality rates were in Guangdong (0.48 [95% UI: 0.39-0.64]/100,000), Zhejiang (0.56 [95% UI: 0.44-0.70]/100,000), and Shanghai (0.57 [95% UI: 0.41-0.73]/100,000). The age-standardized DALY rates across the country and in provinces, municipalities, and autonomous regions generally decreased as their SDI increased.
CONCLUSIONS
The disease burden of epilepsy is still heavy in China, especially in the western provinces. The incidence and prevalence of epilepsy increased between 1990 and 2019, and the burden of epilepsy in the elderly increases gradually. This study provides evidence on epilepsy prevention and care of different regions in China.
