Objective To investigate the relationship between the expression of long non-coding RNA HOXA-AS2(lncRNA HOXA-AS2),long non-coding RNA FOXD2-AS1(lncRNA FOXD2-AS1),and long non-coding RNA CRNDE(lncRNA CRNDE)in endometrial carcinoma and the clinical pathological character-istics and prognosis of patients.Methods Collect samples of endometrial carcinoma cancer tissues and adja-cent tissues excised during surgery from 119 endometrial carcinoma patients admitted to a hospital from Octo-ber 2017 to February 2020.The relative expression levels of HOXA-AS2,FOXD2-AS1 and CRNDE in tissues were retrospectively analyzed,as well as their relationship with clinicopathological features and 3-year survival rate of patients.Results The relative expression levels of HOXA-AS2,FOXD2-AS1 and CRNDE in cancer tissues of endometrial carcinoma patients were higher than those in adjacent tissues,with statistical signifi-cance(P＜0.05).The relative expression levels of HOXA-AS2,FOXD2-AS1 and CRNDE in cancer tissues of endometrial carcinoma patients were positively correlated(rHOXA-As2 vs.FOXD2-AS1=0.384,P=0.001;rHoXA-AS2 vs.CRNDE=0.576,P＜0.001;rFoXD2-AS1 vs.CRNDE=0.326,P=0.003).In the HOXA-AS2,FOXD2-AS1 and CRNDE high expression group,the proportion of patients with international federation of gynecology and ob-stetrics(FIGO)stage Ⅲ+Ⅳ,lymph node metastasis,deep infiltration and low differentiation was higher than that in the low expression group,with statistical significance(P＜0.05).The 3-year survival rate of low HOXA-AS2 expression group in endometrial cancer patients(52/60,86.67％)was higher than that of high HOXA-AS2 expression group(40/59,67.79％),the difference was statistically significant(x2=6.039,P＜0.05).The 3-year survival rate of patients with endometrial cancer with low FOXD2-AS1 expression group(53/59,89.83％)was higher than that of patients with endometrial cancer with high FOXD2-AS1 expression group(39/60,65.00％),and the difference was statistically significant(x2=10.456,P＜0.05).The 3-year sur-vival rate of low CRNDE expression group in endometrial cancer patients(51/60,85.00％)was higher than that of high CRNDE expression group(41/59,69.49％),and the difference was statistically significant(x2=4.079,P＜0.05).HOXA-AS2,FOXD2-AS1,and CRNDE were risk factors for death in endometrial carcinoma patients(P＜0.05).Conclusion The expression of HOXA-AS2,FOXD2-AS1,and CRNDE in endometrial carcinoma cancer tissue is closely related to the clinical pathological characteristics and prognosis of patients.

Di-(2-ethylhexyl) phthalate (DEHP) is currently one of the most widely used plasticizers, widely found in all kinds of items, such as children’s toys and food packaging materials, but also added to wallpaper, cable protective agents and other building decoration materials. DEHP is toxic and absorbed by the human body through respiratory tract, digestive tract and skin contact, which can cause damage to multiple systems, especially the male reproductive system, and testis is an important target organ. Oxidative stress injury is the core mechanism of spermatogenesis disorder caused by DEHP. DEHP exposure can cause oxidative stress or reactive oxygen species (ROS) increase in germ cells, and on this basis, promote cell apoptosis or cause excessive autophagy. The toxicity of DEHP to Leydig cells is mainly to interfere with the synthesis of steroid hormones. For Sertoli cells, ferroptosis and destruction of the blood-testis barrier are common injury mechanisms. In addition, gene methylation caused by DEHP not only affects the spermatogenic process, but also has epigenetic effects on offspring. In this paper, we reviewed the pathological damage, germ cell toxicity and epigenetic effects of DEHP on testis, and focused on the damage and molecular mechanism on testicular spermatogenic cells, Leydig cells and Sertoli cells. Future research is required to elucidate the body’s clearance mechanism and treatment plan after exposure to DEHP and whether DEHP will damage the function of myoid cells. It is hoped that this can provide new ideas for prevention and treatment of male reproductive disorders resulting from long-term exposure to plastic products.

Objective To investigate the risk factors for bronchopulmonary dysplasia(BPD)in twin preterm infants with a gestational age of<34 weeks,and to provide a basis for early identification of BPD in twin preterm infants in clinical practice.Methods A retrospective analysis was performed for the twin preterm infants with a gestational age of<34 weeks who were admitted to 22 hospitals nationwide from January 2018 to December 2020.According to their conditions,they were divided into group A(both twins had BPD),group B(only one twin had BPD),and group C(neither twin had BPD).The risk factors for BPD in twin preterm infants were analyzed.Further analysis was conducted on group B to investigate the postnatal risk factors for BPD within twins.Results A total of 904 pairs of twins with a gestational age of<34 weeks were included in this study.The multivariate logistic regression analysis showed that compared with group C,birth weight discordance of>25%between the twins was an independent risk factor for BPD in one of the twins(OR=3.370,95%CI:1.500-7.568,P<0.05),and high gestational age at birth was a protective factor against BPD(P<0.05).The conditional logistic regression analysis of group B showed that small-for-gestational-age(SGA)birth was an independent risk factor for BPD in individual twins(OR=5.017,95%CI:1.040-24.190,P<0.05).Conclusions The development of BPD in twin preterm infants is associated with gestational age,birth weight discordance between the twins,and SGA birth.

Objective To summarize the reasons and management strategies of reoperation after oblique lateral interbody fusion(OLIF),and put forward preventive measures.Methods From October 2015 to December 2019,23 patients who under-went reoperation after OLIF in four spine surgery centers were retrospectively analyzed.There were 9 males and 14 females with an average age of(61.89±8.80)years old ranging from 44 to 81 years old.The index diagnosis was degenerative lumbar intervertebral dics diseases in 3 cases,discogenie low back pain in 1 case,degenerative lumbar spondylolisthesis in 6 cases,lumbar spinal stenosis in 9 cases and degenerative lumbar spinal kyphoscoliosis in 4 cases.Sixteen patients were primarily treated with Stand-alone OLIF procedures and 7 cases were primarily treated with OLIF combined with posterior pedicle screw fixation.There were 17 cases of single fusion segment,2 of 2 fusion segments,4 of 3 fusion segments.All the cases underwent reoperation within 3 months after the initial surgery.The strategies of reoperation included supplementary posterior pedicle screw instrumentation in 16 cases;posterior laminectomy,cage adjustment and neurolysis in 2 cases,arthroplasty and neuroly-sis under endoscope in 1 case,posterior laminectomy and neurolysis in 1 case,pedicle screw adjustment in 1 case,exploration and decompression under percutaneous endoscopic in 1 case,interbody fusion cage and pedicle screw revision in 1 case.Visu-al analogue scale(VAS)and Oswestry disability index(ODI)index were used to evaluate and compare the recovery of low back pain and lumbar function before reoperation and at the last follow-up.During the follow-up process,the phenomenon of fusion cage settlement or re-displacement,as well as the condition of intervertebral fusion,were observed.The changes in in-tervertebral space height before the first operation,after the first operation,before the second operation,3 to 5 days after the second operation,6 months after the second operation,and at the latest follow-up were measured and compared.Results There was no skin necrosis and infection.All patients were followed up from 12 to 48 months with an average of(28.1±7.3)months.Nerve root injury symptoms were relieved within 3 to 6 months.No cage transverse shifting and no dislodgement,loosening or breakage of the instrumentation was observed in any patient during the follow-up period.Though the intervertebral disc height was obviously increased at the first postoperative,there was a rapid loss in the early stage,and still partially lost after reopera-tion.The VAS for back pain recovered from(6.20±1.69)points preoperatively to(1.60±0.71)points postoperatively(P＜0.05).The ODI recovered from(40.60±7.01)％preoperatively to(9.14±2.66)％postoperatively(P＜0.05).Conclusion There is a risk of reoperation due to failure after OLIF surgery.The reasons for reoperation include preoperative bone loss or osteoporosis the initial surgery was performed by Stand-alone,intraoperative endplate injury,significant subsidence of the fusion cage after surgery,postoperative fusion cage displacement,nerve damage,etc.As long as it is discovered in a timely manner and handled properly,further surgery after OLIF surgery can achieve better clinical results,but prevention still needs to be strengthened.

This article summarizes the clinical experience in treatment of refractory tinnitus with He's santong therapy of acupuncture (three techniques of acupuncture to remove the blockage and promote circulation). Refractory tinnitus is characterized by a mixture of deficiency and excess, which is implicated in the dysfunction of zangfu organs, resulting in physical and mental injuries. In association with the complicated conditions of the diseases and etiology, He's santong therapy of acupuncture is adopted. The needling with filiform needles acts directly on the affected site to regulate the mind and improve the hearing, the fire needling works on removing the refractory illness and blockage through heating up, and bloodletting on activating blood circulation and promoting qi flowing to eliminate the pathogens. The three techniques of acupuncture co-work on harmonizing the mind, promoting the circulations in the ear to stop tinnitus.

Objective:To evaluate the effect of remimazolam on hemodynamics when used for anesthesia induction in patients undergoing coronary artery bypass grafting (CABG).Methods:Sixty patients of either sex, aged 18-64 yr, of American Society of Anesthesiologists Physical Status classification Ⅱ-Ⅲ, with ejection fraction>35%, cardiac index (CI) >2.0 L·min -1·m -2 and body mass index <28 kg/m 2, undergoing CABG under general anesthesia, were divided into 2 groups ( n=30 each)using a random number table method: remazolam group (group R) and midazolam group (group M). Group R received intravenous remimazolam 0.08 mg/kg, and group M received intravenous midazolam 0.05 mg/kg, and both groups used sufentanil, etomidate, and rocuronium bromide for anesthesia induction to maintain the BIS value at 40-65. Before anesthesia induction, at 1-2 min after intravenous injection of remimazolam/midazolam-sufantanil-etomidate, immediately before tracheal incubation, at 30 s-15 min after tracheal intubation, and immediately before skin incision, blood pressure, heart rate, mean arterial pressure, CI, stroke volume index, systemic vascular resistance index, and left heart systolic index were measured, and vasoactive drugs were used to maintain the stability of vital signs and to record the cardiovascular events. Results:Compared with group M, the incidence of hypotension and usage rate of vasoactive drugs were significantly decreased, and the incidence of decrease in CI and stroke volume index by more than 20% and changes in left heart systolic index were decreased in group R( P<0.05). Conclusions:Remimazolam can reduce the disturbance of hemodynamics to a certain extent when used for anesthesia induction as compared with midazolam in patients undergoing CABG.

OBJECTIVE To evaluate the effectiveness， safety， economy， innovation， suitability and accessibility of recombinant Mycobacterium tuberculosis fusion protein （EC）， and to provide evidence for selecting skin detection methods for tuberculosis infection diagnosis and auxiliary diagnosis of tuberculosis. METHODS The effectiveness and safety of EC compared with purified protein derivative of tuberculin （TB-PPD） were analyzed by the method of systematic review. Cost minimization analysis， cost-effectiveness analysis and cost-utility analysis were used to evaluate the short-term economy of EC compared with TB-PPD， and cost-utility analysis was used to evaluate the long-term economy. The evaluation dimensions of innovation， suitability and accessibility were determined by systematic review and improved Delphi expert consultation， and the comprehensive score of EC and TB-PPD in each dimension were calculated by the weight of each indicator. RESULTS The scores of effectiveness， safety， economy， innovation and suitability of EC were all higher than those of TB-PPD. The affordability scores of the two drugs were consistent， while the availability score of EC was lower than those of TB-PPD. After considering dimensions and index weight， the scores of effectiveness， safety， economy， innovation， suitability， accessibility and the comprehensive score of EC were all higher than those of TB-PPD. CONCLUSIONS Compared with TB-PPD， EC performs better in all dimensions of effectiveness， safety， economy， innovation， suitability and accessibility. However， it is worth noting that EC should further improve its availability in the dimension of accessibility.

Objective:To analyze the impact of COVID-19 on the number of hospitalization and the disease spectrum of children′s hospitals in China, so as to provide scientific basis for improving the epidemic response policy of children′s hospitals and restoring hospital operations.Methods:Discharged patients from 27 children′s hospitals from January 1, 2019, to December 31, 2020, were selected from the FUTang Updating medical Records(FUTURE) Database. The ratio of discharge number in 2020 to that in 2019 was calculated. Age groups, disease types, and discharge months were further divided to calculate the ratio of discharge numbers under different conditions.Results:The total number of discharged patients in 2020 was 76.76% of the total number in 2019. In terms of discharge time, the ratio rose slowly from the lowest values in February and March, and reached about 90% of the same period of 2019 at the end of 2020. In terms of age, the biggest change in the discharge number was among children aged 1-3 years, which was 71.87% in 2019. In terms of disease classifications, respiratory diseases changed the most in the number of discharged patients in 2020, accounting for 56.03% of that in 2019. The top five hospitalized diseases of children did not change, while the other ranks changed slightly.Conclusions:COVID-19 has a huge and lasting impact on the number of hospitalizations in children′s hospitals, and the hospitals should develop multiple approaches such as online medical care to cope with the long-term negative impact of the pandemic.

Lower extremity deep vein thrombosis (DVT) is one of the main complications in patients with traumatic fractures, and for severe patients, the DVT can even affect arterial blood supply, resulting in insufficient limb blood supply. If the thrombus breaks off, pulmonary embolism may occur, with a high mortality. The treatment and rehabilitation strategies of thrombosis in patients with lower extremity fractures have its particularity. DVT in traumatic fractures patients has attracted extensive attention and been largely studied, and the measures for prevention and treatment of DVT are constantly developing. In recent years, a series of thrombosis prevention and treatment guidelines have been updated at home and abroad, but there are still many doubts about the prevention and treatment of DVT in patients with different traumatic fractures. Accordingly, on the basis of summarizing the latest evidence-based medical evidence at home and abroad and the clinical experience of the majority of experts, the authors summarize the clinical treatment and prevention protocols for DVT in patients with traumatic fractures, and make this consensus on the examination and assessment, treatment, prevention and preventive measures for DVT in patients with different fractures so as to provide a practicable approach suitable for China ′s national conditions and improve the prognosis and the life quality of patients.

OBJECTIVE: To investigate the incidence of Runt-related transcription factor 1 (RUNX1) gene and its associated gene mutations in patients with acute myeloid leukemia (AML), and analyze its clinical characteristics and prognosis. METHODS: The genomic DNA-PCR method was used to detect the exon of RUNX1 gene, and the gene mutations were analyzed by genetic sequencing. NPM1, DNMT3A, FLT3-ITD, IDH1/2, K/N-RAS, CEPBA, TET2, and WT1 co-mutations were also detected. Patients were followed up to determine efficacy and prognosis. RESULTS: Among 171 patients, the RUNX1 gene mutation was detected in 17 cases, and the mutation rate was 9.9%. The type of RUNX1 gene mutation was 9 missense mutations, 4 frameshift mutations, and 4 nonsense mutations. The peripheral blood leukocyte count of the patients in mutation group was 3 (1-101) ×10 CONCLUSION AML patients with RUNX1 gene mutation shows unique clinical and biological characteristics, RUNX1 mutation can be regarded as a molecular marker of poor prognosis in AML patients.
