Objective To compare the safety and effectiveness of three types of intrauterine device (IUD) inserted immediately after artificial abortion.Methods A randomized controlled clinical trial was performed in 4 family planning service stations in Pudong New Area from January to December 2012.Total 1 200 eligible women were randomly assigned to receive three types of IUD:MYCu,TCu380A or G-Cu200 (n =400 in each group) immediately after vacuum aspiration.All subjects were followed up for 12 months.The cumulative rates of termination of three IUD after 12 months were analyzed with WHO LTA 2.0 life table.Results Total 1 199 subjects were followed up for 12 months with a drop-out rate of 0.08％ (1/1 200).No any uterine perforation was found.During the 12 months the pregnancy rates with IUD in situ in MYCu,TCu380A and G-Cu200 groups were 0.26/100 women year,0 and 0.52/100 women year,respectively (x2 =1.951,P ≥ 0.2).The rates of expulsion in three groups were 0.26/100 women year,1.84/100 women year and 2.05/100 women year,respectively(x2 =5.539,P =0.066).The remove rates related to bleeding and paining in three groups were 1.26/100 women year,7.29/100 women year and 2.76/100 women year,respectively (x2 =21.625,P =0.001).The discontinuation rates related to IUD use in there groups were 3.25/100 women year,9.00/100 women year and 5.50/100 women year,respectively(x2 =12.191,P =0.004).The rates of Abnormal position in three groups were 1.51/100 women year,0 and 0.26/100 women year,respectively (x2 =8.649,P =0.014).Conclusion Three IUDs inserted immediately after vacuum aspiration are all effective.Among three IUDs,MYCu shows lower expulsion rate,lower discontinuation rate related to IUD use and higher continuous rate; but the abnormal position rate of MYCu is higher than other two types IUD.

Objective To evaluate the relationship between endoplasmic reticulum stress and diabetes mellitus (DM)-caused influence on cardioprotection induced by remifentanil postconditioning in rats.Methods Adult male Sprague-Dawley rats,weighing 250-300 g,were used in the study.A model for type 1 DM was established by intraperitoneal streptozotocin 50 mg/kg and confirmed by blood glucose ≥ 16.7 mmol/L.Thirty six rats with type 1 DM were randomly divided into 3 groups (n =12 each) using a random number table:sham operation group (DM-S group),myocardial ischemia-reperfusion (I/R) group (DM-I/R group) and remifentanil postconditioning group (DM-R group).Another 36 normal rats were exposed to single intraperitoneal injection of sodium citrate-hydrochloric acid buffer solution and served as control group.Two weeks later 36 normal rats with nondiabetes mellitus were also randomly divided into 3 groups (n =12 each) using a random number table:sham operation group (NDM-S group),myocardial I/ R group (NDM-I/R group) and remifentanil postconditioning group (NDM-R group).Myocardial I/R was produced by 30 min occlusion of left anterior descending branch of coronary artery followed by 120 min reperfusion.Remifentanil postconditioning was induced by 10 min infusion of remifentanil 10 μg · kg-1 · min 1 via the femoral vein starting from 5 min before reperfusion.Before ischemia and at 30 and 120 min of ischemia,MAP,SP and HR were recorded and rate-pressure product (RPP) was calculated.At 120 min of reperfusion,arterial blood samples were collected for measurement of plasma cardiac troponin I (cTnI) concentration.The animals were then sacrificed and hearts were removed for determination of myocardial infarct size (IS).The left 6 rats from each group were sacrificed at 120 min of reperfusion,the specimens from their left ventricular apex were obtained to detect the expression of endoplasmic reticulum stress marker glucose-regulated protein 78 (GRP78),C/EBP homologous protein (CHOP) and caspase-12 by Western blot.Results MAP and RPP were significantly decreased,the plasma concentration of cTnI was increased,changes of cardiac infarction were found,and the expression of GRP78,CHOP and caspase-12 was up-regulated in diabetic and nondiabetic rats.Remifentanil postconditioning could inhibit the expression of GRP78,CHOP and caspase-12,increase MAP and RPP,decrease the plasma concentration of cTnI,and reduce myocardial infarct size in nondiabetic rats,but it had no such effects in the diabetic rats.The expression of GRP78,CHOP and caspase-12 was significantly higher after remifentanil postconditioning in diabetic rats than in nondiabetic rats.Conclusion Enhanced endoplasmic reticulum stress is involved in DM-caused loss of cardioprotection induced by remifentanil postconditioning in rats.

Objective:To analyze circRNAs specifically differentially expressed in esophageal squamous cell carcinoma (ESCC) based on high-throughput sequencing data.Methods:Six patients with pathologically confirmed ESCC in Tangdu Hospital of Air Force Medical University from March 2018 to March 2019 were selected as the research subjects, among which 3 were stage Ⅰ ESCC and 3 were stage Ⅲ ESCC. High-throughput sequencing technology was used to analyze the difference in the expression of circRNA in cancer tissues and adjacent tissues of patients. GO enrichment analysis, KEGG enrichment analysis and Venn analysis were performed on differentially expressed genes. The circRNA-miRNA-mRNA network was constructed using Cytoscape software. The most significantly differentially expressed genes in cancer tissues were verified in cells and tissues, and the relationships between circRNAs and clinical pathological indicators of patients were analyzed.Results:A total of 553 differentially expressed circRNAs were screened in paracancerous tissues and cancer tissues of 3 stage Ⅰ ESCC patients, of which 413 were up-regulated and 140 were down-regulated in cancer tissues; A total of 425 differentially expressed circRNAs were screened in paracancerous tissues and cancer tissues of 3 stage Ⅲ ESCC patients, of which 276 were up-regulated and 149 were down-regulated in cancer tissues. GO enrichment analysis showed that the host genes of differential circRNAs in patients with stage Ⅰ ESCC were mainly enriched in cell cycle-related biological processes such as mitotic G 2/M transition. The host genes of differential circRNAs in patients with stage Ⅲ ESCC were mainly enriched in biological processes related to cell division and tumor development, such as mitotic spindle checkpoint and cell matrix adhesion. KEGG enrichment analysis showed that the differential circRNAs in cancer tissues of stage Ⅰ and stage Ⅲ ESCC patients were mainly enriched in cancer-related biological pathways such as cell adhesion. The results of Venn analysis showed that in stage Ⅰ ESCC patients and stage Ⅲ ESCC patients, 2 and 8 circRNAs that were only specifically expressed in paracancerous tissues and had significant differences were screened out respectively, and were only specifically expressed in cancer tissues with significant differences were 11 and 14 respectively. The circRNA-miRNA-mRNA network showed that the cancer tissue-related circRNA-miRNA-mRNA network in stage Ⅰ ESCC patients consisted of 7 circRNA nodes, 10 miRNA nodes and 28 mRNA nodes, and the cancer tissue-related circRNA-miRNA-mRNA network in stage Ⅲ ESCC patients consisted of 7 circRNA nodes, 9 miRNA nodes and 49 mRNA nodes. The most significantly differentially expressed hsa-circ-0060927 and hsa-circ-0109301 in cancer tissues of patients with stage Ⅰ ESCC and stage Ⅲ ESCC were selected for cytological and histological verification. The results showed that the relative expression levels of hsa-circ-0060927 in ESCC cell lines TE1, TE13, KYSE30, KYSE170, and human normal esophageal epithelial cell line HEEC were 7.82±1.96, 12.69±2.68, 12.78±2.74, 7.53±1.75, and 2.43±0.17, respectively, with a statistically significant difference ( F=4.68, P=0.004). The relative expression levels of hsa-circ-0060927 in ESCC cell lines TE1, TE13, KYSE30, and KYSE170 were higher than that in human normal esophageal epithelial cell line HEEC, with statistically significant differences ( P=0.009; P=0.003; P=0.003; P=0.007). The relative expression levels of hsa-circ-0109301 in ESCC cell lines TE1, TE13, KYSE30, KYSE170, and human normal esophageal epithelial cell line HEEC were 5.16±1.32, 6.28±1.57, 4.89±1.13, 8.92±2.12, and 22.56±4.13, respectively, with a statistically significant difference ( F=4.31, P=0.022). The relative expression levels of hsa-circ-0109301 in ESCC cell lines TE1, TE13, KYSE30, and KYSE170 were lower than that in human normal esophageal epithelial cell line HEEC, with statistically significant differences ( P=0.027; P=0.015; P=0.024; P=0.008). The expression level of hsa-circ-0060927 in cancer tissues of 13 early ESCC patients was 12.89±2.67, significantly higher than 5.73±1.18 in paracancerous tissue, and there was a statistically significant difference ( t=15.02, P<0.001) ; the expression level of hsa-circ-0109301 in cancer tissues of 19 patients with advanced ESCC was 7.78±2.17, significantly lower than 16.32±3.15 in paracancerous tissue, and there was a statistically significant difference ( t=9.73, P<0.001). The expression of hsa-circ-0109301 was related to the degree of tumor differentiation in advanced ESCC patients ( P=0.023) . Conclusion:One circRNA (hsa-circ-0060927 and hsa-circ-0109301) with the most significanty differential expression is selected in early and advanced ESCC patients respectively, in which hsa-circ-0060927 is highly expressed in ESCC cancer tissues and hsa-circ-0109301 is lowly expressed in ESCC cancer tissues, and the expression of hsa-circ-0109301 is correlated with the degree of tumor differentiation.

Objective To evaluate the clinical value of holographic image navigation in urological laparoscopic and robotic surgery.Methods The data of patients were reviewed retrospectively for whom accepted holographic image navigation laparoscopic and robotic surgery from Jan.2019 to Dec.2019 in Beijing United Family Hospital and other 18 medical centers,including 78 cases of renal tumor,2 cases of bladder cancer,2 cases of adrenal gland tumor,1 cases of renal cyst,1 case of prostate cancer,1 case of sweat gland carcinoma with lymph node metastasis,1 case of pelvic metastasis after radical cystectomy.All the patients underwent operations.In the laparoscopic surgery group,there were 27 cases of partial nephrectomy,1 case of radical prostatectomy,2 cases of radical cystectomy and 2 cases of adrenalectomy.In the da Vinci robotic surgery group of 54 cases,there were 51 cases of partial nephrectomy,1 case of retroperitoneal lymph node dissection,1 case of retroperitoneal bilateral renal cyst deroofing and 1 case of resection of pelvic metastasis.There were 41 partial nephrectomy patients with available clinical data for statistic,with a median age of 53.5 years (range 24-76),including 26 males and 15 females.The median R.E.N.A.L score was 7.8 (range 4-11).Before the operation,the engineers established the holographic image based on the contrast CT images and reports.The surgeon applied the holographic image for preoperative planning.During the operation,the navigation was achieved by real time fusing holographic images with the laparoscopic surgery images in the screen.Results All the procedures had been complete uneventfully.The holographic images helped surgeon in understanding the visual three-dimension structure and relation of vessels supplying tumor or resection tissue,lymph nodes and nerves.By manipulating the holographic images extracorporeally,the fused image guide surgeons about location vessel,lymph node and other important structure and then facilitate the delicate dissection.For the 41 cases with available clinical data including 23 cases of robotic-assisted partial nephrectomy and 18 cases of laparoscopic nephrectomy,the median operation time was 140 (range 50-225) min,the median warm ischemia time was 23 (range 14-60) min,the median blood loss was 80(range 5-1 200) ml.In the robotic surgery group,the median operation time was 140 (range 50-215)min,the median warm i schemia time was 21 (range 17-40)min,the median blood loss was 150(range 30-1 200)ml.In the laparoscopic surgery group,the median operation time was 160(range 80-225)min,the median warm ischemia time was 25 (range 14-60)min,the median blood loss was 50 (range 5-1 200) ml.All the patients had no adjacent organ injury during operation.There were 2 cases with Clavien Ⅱ complications.One required transfusion and the other one suffered hematoma post-operation.However,the tumors were located in the renal hilus for these 2 cases and the R.E.N.A.L scores were both 11.Conclusions Holographic image navigation can help location and recognize important anatomic structures during the surgical procedures..This technique will reduce the tissue injury,decrease the complications and improve the success rate of surgery.

During coronavirus disease 2019 epidemic, the treatment of severe trauma has been impacted. The Consensus on emergency surgery and infection prevention and control for severe trauma patients with 2019 novel corona virus pneumonia was published online on February 12, 2020, providing a strong guidance for the emergency treatment of severe trauma and the self-protection of medical staffs in the early stage of the epidemic. With the Joint Prevention and Control Mechanism of the State Council renaming "novel coronavirus pneumonia" to "novel coronavirus infection" and the infection being managed with measures against class B infectious diseases since January 8, 2023, the consensus published in 2020 is no longer applicable to the emergency treatment of severe trauma in the new stage of epidemic prevention and control. In this context, led by the Chinese Traumatology Association, Chinese Trauma Surgeon Association, Trauma Medicine Branch of Chinese International Exchange and Promotive Association for Medical and Health Care, and Editorial Board of Chinese Journal of Traumatology, the Chinese expert consensus on emergency surgery for severe trauma and infection prevention during coronavirus disease 2019 epidemic ( version 2023) is formulated to ensure the effectiveness and safety in the treatment of severe trauma in the new stage. Based on the policy of the Joint Prevention and Control Mechanism of the State Council and by using evidence-based medical evidence as well as Delphi expert consultation and voting, 16 recommendations are put forward from the four aspects of the related definitions, infection prevention, preoperative assessment and preparation, emergency operation and postoperative management, hoping to provide a reference for severe trauma care in the new stage of the epidemic prevention and control.

Primary age-related tauopathy (PART) is characterized by tau neurofibrillary tangles (NFTs) in the absence of amyloid plaque pathology. In the present study, we analyzed the distribution patterns of phosphorylated 43-kDa TAR DNA-binding protein (pTDP-43) in the brains of patients with PART. Immunohistochemistry and immunofluorescence double-labeling in multiple brain regions was performed on brain tissues from PART, Alzheimer's disease (AD), and aging control cases. We examined the regional distribution patterns of pTDP-43 intraneuronal inclusions in PART with Braak NFT stages > 0 and ≤ IV, and a Thal phase of 0 (no beta-amyloid present). We found four stages which indicated potentially sequential dissemination of pTDP-43 in PART. Stage I was characterized by the presence of pTDP-43 lesions in the amygdala, stage II by such lesions in the hippocampus, stage III by spread of pTDP-43 to the neocortex, and stage IV by pTDP-43 lesions in the putamen, pallidum, and insular cortex. In general, the distribution pattern of pTDP-43 pathology in PART cases was similar to the early TDP-43 stages reported in AD, but tended to be more restricted to the limbic system. However, there were some differences in the distribution patterns of pTDP-43 between PART and AD, especially in the dentate gyrus of the hippocampus. Positive correlations were found in PART between the Braak NFT stage and the pTDP-43 stage and density.
