RESUMEN
Objective:To explore the practical value of general anesthesia with non-intubated spontaneous breathing in uniportal thoracoscopic surgery in elderly patients.Methods:Clinical data of 86 elderly patients undergone uniportal thoracoscopy surgery during hospitalization at our hospital between March 2020 and December 2021 were retrospectively reviewed and analyzed.Based on the anesthesia intubation method, they were divided into a non-intubated spontaneous breathing video-assisted thoracic surgery group(NI-VATS group)and a one-lung ventilation video-assisted thoracic surgery group(OLV-VATS group), with 43 cases in each group.Data were compared on the inflammatory indexes, preparation time for anesthesia, time to awakening after anesthesia, intraoperative lung collapse score, mediastinal flutter score, time to postoperative feeding, digestive tract complications, sore throat, postoperative pulmonary atelectasis, and hospitalization time.Results:Compared with the OLV-VATS group, the NI-VATS group had a shorter anesthesia preparation time [(19.8±2.6)min vs.(32.3±4.5)min, t=-15.77, P<0.001]and a shorter time to awakening [(6.8±2.1)min vs.(11.9±2.9)min, t=-9.485, P<0.001], slightly poorer operating field during surgery, an unfavorable lung collapse score [(2.5±0.7) vs.(1.8±0.7) t=4.704, P<0.001], worse mediastinal flutter [(2.1±0.6) vs.(1.3±0.5), t=6.514, P<0.001]. Lower procalcitonin(PCT)[(0.189±0.130)μg/L vs.(0.264±0.123)μg/L, t=-2.744, P=0.007), a shorter time to postoperative feeding [(3.4±1.0)h vs.(5.5±1.0)h, t=-9.55, P<0.001], and lower rates of digestive tract reactions(4.7% vs.20.9%, χ2=5.108, P=0.024)and throat pain(4.7% vs.23.3%, χ2=6.198, P=0.013), and a shorter length of hospital stay [(3.8±0.3)d vs.(4.9±0.8)d, t=-7.266, P<0.001]. Conclusions:For the elderly patients undergoing uniportal thoracoscopic surgery, non-intubated spontaneous breathing may somewhat obstruct the operating field, but it can shorten the time of anesthesia and the time to awakening, does not increase complications from anesthesia and surgery, favors rapid postoperative recovery for patients and therefore should be promoted.
RESUMEN
After radiotherapy for pelvic malignancies, pelvic insufficiency fracture (PIF), as a type of late injury event for pelvic bones, cannot be ignored, because it can exert a detrimental effect on patients' quality of life, and might make patients disabled and threaten their lives. Meanwhile, PIF is likely to be misdiagnosed with bone metastases. In this article, research progresses on potential pathogenesis, general characteristics, risk factors, diagnosis and treatment for PIF were reviewed.
RESUMEN
Radiotherapy is an important treatment method for cervical cancer and endometrial cancer, and the therapeutic effect mainly depends on the precise tumor irradiation and the protection of normal tissues. Radiomics obtains comprehensive information features of tumors from medical images in a non-invasive and high-throughput manner. Establishing radiomics models according to these features helps to delineate the target volume and organs at risk of radiotherapy, and accurately predict the efficacy and toxicity of radiotherapy. Here, the basic process of establishing models using radiomics method and the progress in application of radiomics in radiotherapy for cervical cancer and endometrial cancer were reviewed.
RESUMEN
Fibrosis is the endpoint of pathological remodeling involving different expressions of non-coding RNA(ncRNA) including long non-coding RNA growth arrest-specific 5 (lncRNA Gas5). Up to now, many studies have demonstrated that lncRNA Gas5 may play a vital regulatory role in the occurrence and development of organ fibrosis including liver, renal and cardiac fibrosis et al. Furthermore, Gas5 may also serve as a biomarker in diagnostic settings for fibrosis diseases. Structurally, IncRNA Gas5 impacts fibrosis via its distinct structural modules. In response to various external stresses, distinct functional complexes on different parts of Gas5 sequence influence cell proliferation and survival, thus affecting the inflammatory process and deposition of extracellular matrix(ECM) in organ fibrosis. However, there is no consensus on the role of Gas5 in fibrosis and its changed expression under various circumstances. In this review, we present an overview of what is known about the effect of Gas5 in organ fibrosis so far and for the first time explain its mechanism in the progression of fibrosis based on its unique structure.

Objective:To explore the application value of automated machine learning (autoML) model in predicting the risk of preeclampsia in the first trimester.Methods:From January 2017 to October 2020, 2 180 singleton pregnant women who were registered in Jinan Second Maternal and Child Health Hospital and underwent pregnancy examination at 12 weeks of gestation were selected. The pregnant women were divided into preeclampsia group (103 cases) and control group (2 077 cases) according to the occurrence of preeclampsia. The differences in clinical data and hematological indexes in the two groups were compared, and the correlation between each index and the risk of preeclampsia was analyzed too. All the pregnant women were randomly divided into training set and test set according to the ratio of 7∶3, and the autogluon autoML algorithm was used to build a variety of machine learning models, and training and cross-validation were performed in the training set to compare the accuracy of the different models. The importance of each index in the autoML model was analyzed, and the autoML model and the logistic regression model were used to predict the risk of preeclampsia in pregnant women in the test set respectively, and the receiver operating characteristic (ROC) curve was used to evaluate the prediction performance of the autoML and the logistic regression model.Results:The age, pre-pregnancy body mass index, body mass index at 12 weeks of gestation, waist circumference at 12 weeks of gestation, proportion of drinking history, high-sensitivity C-reactive protein (hs-CRP), triglyceride, low-density lipoprotein cholesterol (LDL-C), aspartate aminotransferase (AST), platelet distribution width (PDW), mean platelet volume, thyroid stimulating hormone (TSH) and β-human chorionic gonadotropin were all significantly higher than those in the control group (all P<0.05), and the free tri-iodothyronine (free T3), free thyroxine (free T4), placental growth factor (PIGF), soluble fms-like tyrosine kinase-1 (sFlt-1) and pregnancy-associated plasma protein-A (PAPP-A) were all significantly lower than those in the control group (all P<0.05). Correlation analysis showed that the correlation between pre-pregnancy body mass index, body mass index at 12 weeks gestation, waist circumference at 12 weeks gestation, hs-CRP, triacylglycerol, AST, TSH, free T3, free T4, β-HCG, PIGF, sFlt-1, PAPP-A and preeclampsia risk were obviously higher; but the correlation between each index were lower. A total of 18 models in 8 categories were constructed with the autoML model algorithm, and the neural network _L2 based on FastAI had the highest accuracy in the training set (0.963) and the validation set (0.971). The TSH, LDL-C, PDW, waist circumference at 12 weeks of gestation, sFlt-1, AST were more important in the model, while the free T4, total cholesterol, pregnancy times, drinking history, parity and family history of hypertension were less important indicators. The area under the ROC curve of the autoML model for predicting the risk of preeclampsia in the first trimester was significantly higher than that of the logistic regression model (0.984 vs 0.765, P=0.002), while there was no statistical difference in the prediction accuracy of the two prediction models in the training set ( P>0.05). The prediction accuracy and sensitivity of the autoML model in the test set were both significantly higher than those of the logistic regression model (99.54% vs 98.32%, 93.75% vs 75.00%, both P<0.05). Conclusions:Factors such as TSH, LDL-C, PDW, waist circumference, sFlt-1 and AST in the first trimester of pregnancy have a certain correlation with the risk of preeclampsia. The autoML model based on the indicators of the first trimester has a high predictive value for the risk of preeclampsia.

RESUMEN
In order to study the signal pathway secreting type Ⅰ interferon in porcine alveolar macrophages (PAMs) infected with porcine circovirus type 2 (PCV2), the protein and the mRNA expression levels of cGAS/STING pathways were analyzed by ELISA, Western blotting and quantitative reverse transcriptase PCR in PAMs infected with PCV2. In addition, the roles of cGAS, STING, TBK1 and NF-κB/P65 in the generation of type I interferon (IFN-I) from PAMs were analyzed by using the cGAS and STING specific siRNA, inhibitors BX795 and BAY 11-7082. The results showed that the expression levels of IFN-I increased significantly at 48 h after infection with PCV2 (P<0.05), the mRNA expression levels of cGAS increased significantly at 48 h and 72 h after infection (P<0.01), the mRNA expression levels of STING increased significantly at 72 h after infection (P<0.01), and the mRNA expression levels of TBK1 and IRF3 increased at 48 h after infection (P<0.01). The protein expression levels of STING, TBK1 and IRF3 in PAMs infected with PCV2 were increased, the content of NF-κB/p65 was decreased, and the nuclear entry of NF-κB/p65 and IRF3 was promoted. After knocking down cGAS or STING expression by siRNA, the expression level of IFN-I was significantly decreased after PCV2 infection for 48 h (P<0.01). BX795 and BAY 11-7082 inhibitors were used to inhibit the expression of IRF3 and NF-κB, the concentration of IFN-I in BX795-treated group was significantly reduced than that of the PCV2 group (P<0.01), while no significant difference was observed between the BAY 11-7028 group and the PCV2 group. The results showed that PAMs infected with PCV2 induced IFN-I secretion through the cGAS/STING/TBK1/IRF3 signaling pathway.

BACKGROUNDIn-depth investigations of the safety and immunogenicity of inactivated SARS-CoV-2 vaccines are needed. METHODIn a phase I randomized, double-blinded, and placebo-controlled trial involving 192 healthy adults 18-59 years of age, two injections of three different doses (50 EU, 100 EU and 150 EU) of an inactivated SARS-CoV-2 vaccine or the placebo were administered intramuscularly with a 2- or 4-week interval between the injections. The safety and immunogenicity of the vaccine were evaluated within 28 days. FINDINGIn this study, 191 subjects assigned to three doses groups or the placebo group completed the 28-day trial. There were 44 adverse reactions within the 28 days, most commonly mild pain and redness at the injection site or slight fatigue, and no abnormal variations were observed in 48 cytokines in the serum samples of immunized subjects. The serum samples diluted from 1:32 to 1:4096 and incubated with the virus did not show antibody-dependent enhancement effects (ADEs) with regard to human natural killer cells, macrophages or dendritic cells. At day 14, the seroconversion rates had reached 92%, 100% and 96% with geometric mean titers (GMTs) of 18.0, 54.5 and 37.1, and at day 28, the seroconversion rates had reached 80%, 96% and 92% with GMTs of 10.6, 15.4 and 19.6in 0, 14 and 0, 28 procedures, respectively. Seroconversion was associated with the synchronous upregulation of ELISA antibodies against the S protein, N protein and virion and a cytotoxic T lymphocyte (CTL) response. Transcriptome analysis shaped the genetic diversity of immune response induced by the vaccine. INTERPRETATIONIn a population aged 18-59 years, this inactivated SARS-CoV-2 vaccine was safe and immunogenic.

RESUMEN
With the relatively serious global epidemic outbreak of SARS-CoV-2 infection, public concerns focus on not only clinical therapeutic measures and public quarantine for this disease but also the development of vaccines. The technical design of our SARS-CoV-2 inactivated vaccine provides a viral antigen that enables the exposure of more than one structural protein based upon the antibody composition of COVID-19 patients convalescent serum. This design led to valid immunity with increasing neutralizing antibody titers and a CTL response detected post-immunization of this vaccine by two injections in rhesus macaques. Further, this elicited immunoprotection in macaques enables not only to restrain completely viral replication in tissues of immunized animals, compared to the adjuvant control and those immunized by an RBD peptide vaccine, but also to significantly alleviate inflammatory lesion in lung tissues in histo-pathologic detection, compared to the adjuvant control with developed interstitial pneumonia. The data obtained from these macaques immunized with the inactivated vaccine or RBD peptide vaccine suggest that immunity with a clinically protective effect against SARS-CoV-2 infection should include not only specific neutralizing antibodies but also specific CTL responses against at least the S and N antigens.
RESUMEN
The coronavirus disease (COVID-19) caused by the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has now spread to more than 100 countries posing as a serious threat to the public health on a global scale. Patients with comorbidity such as hypertension suffer more severe infection with elevated case fatality rate. Development of effective anti-viral drug is in urgent need to treat COVID-19 patients. Here we report that calcium channel blockers (CCBs), a type of anti-hypertension drugs that are widely used in the clinics, can significantly inhibit the post-entry replication events of SARS-CoV-2 in vitro. Comparison with two other major types of anti-hypertension drugs, the angiotensin converting enzyme inhibitors (ACEI) and angiotensin II receptor blockers (ARB), showed that only CCBs display significant anti-SARS-CoV-2 efficacy. Combined treatment with chloroquine and CCBs significantly enhanced the anti-SARS-CoV-2 efficacy. Retrospective clinical investigation of COVID-19 patients revealed that the CCB amlodipine besylate administration was associated with reduced case fatality rate of patients with hypertension. Results from this study suggest that CCB administration for COVID-19 patients with hypertension as the comorbidity might improve the disease outcome.
RESUMEN
Objective:To improve the Rapid Arterial Occlusion Evaluation (RACE) scale and to investigate its value in identifying large vessel occlusion (LVO) in patients with acute anterior circulation ischemic stroke (AIS).Methods:Consecutive patients with AIS treated in Liangxiang Hospital of Fangshan District, Beijing through stroke easy access from January 1, 2016 to December 31, 2018 were enrolled prospectively. The clinical data and multimodal CT examinations required to determine LVO were collected. The existing problems in the RACE score were modified. The patients were evaluated by the modified RACE score, RACE score, and National Institute of Health Stroke Scale (NIHSS). The receiver operator characteristic (ROC) curve was used to evaluate the predictive ability of the modified RACE score for LVO, and it was compared with the RACE score and NIHSS score. The ROC curves of LVO predicted by modified RACE score and NIHSS score in patients with left and right hemispheric lesions were compared.Results:A total of 184 patients were included, of which 66 (35.9%) had LVO. The age (64.8±11.7 vs. 60.5±10.8 years; t=2.483, P=0.014), baseline NIHSS score (13 [6.75-17] vs. 5 [2-9]; Z=-6.361, P<0.001) and the proportion of patients with gaze (37.9% vs. 17.4%; χ2=4.696, P=0.030) in the LVO group were significantly higher than those in the non-LVO group. ROC curve showed that the modified RACE score was more effective in identifying LVO than RACE score (area under the curve: 0.812 vs. 0.770; Z=4.654, P<0.001). The best cutoff value of the modified RACE score in predicting LVO was 5, and its predictive sensitivity and specificity were 75.8% and 75.4%, respectively, and the positive and negative predictive values were 63.3% and 84.8%, respectively. A comparison of patients with left hemispheric lesion and those with right hemispheric lesion showed that the ability of the modified RACE score in predicting LVO was more balanced (area under the curve: 0.826 vs. 0.796; Z=0.454, P=0.650), while there was a significant difference in NIHSS score (area under the curve: 0.856 vs. 0.703; Z=2.149, P=0.031). Conclusions:The modified RACE score is better than the original RACE score in the predictive value of LVO in patients with AIS, and its predictive power of LVO in patients with left and right hemisphere stroke is more balanced than the NIHSS score, which may help clinical discrimination and screening for patients suitable endovascular treatment.

RESUMEN
There is a high risk of myelosuppression in pelvic malignant tumors during concurrent chemoradiotherapy. The dose-volume relationship of pelvic exposed bone marrow( bone) is related to acute hematological toxicity during radiotherapy and chemotherapy,but lacks recognized parameters in this respect. The hematopoietic capacity of the bone marrow(bone)in different parts of the pelvic cavity is heterogeneous,and the pelvic bone marrow near the central axis has the strongest hematopoietic capacity,namely functional bone marrow. The relationship between dose-volume parameters of pelvic functional bone marrow and acute hematologic toxicity during chemoradiotherapy of pelvic malignant tumors may be the future direction.
RESUMEN
To investigate and analyze the clinical characteristics and prognosis of brain-heart interaction (BHI) in patients with acute severe stroke. Methods The patients with acute severe stroke admitted to Neurointensive Care Unit of Xuanwu Hospital, Capital Medical University from January 1st, 2015 to December 31st, 2017 were enrolled. The clinical data, indicators related to BHI and prognosis were collected. Patients were divided into BHI group and non-BHI group according to the presence or absence of BHI. The differences of each index were compared between two groups. The independent risk factors of BHI were analyzed using multivariate Logistic regression analysis. In addition, subgroup analysis was performed for patients in the BHI group based on the presence or absence of Takotsubo syndrome (TTS), and multivariate Logistic regression was used to analyze independent risk factors for TTS. Results 119 patients with acute severe stroke were analyzed, BHI occurred in 91 cases (76.5%), and 17 cases (14.3%) TTS were included in the BHI group. Compared with non-BHI group, BHI group had lower rates of cerebrovascular disease history (20.9% vs. 42.9%, P = 0.020), lower smoking history (25.3% vs. 50.0%, P = 0.013), lower statin use (16.5% vs. 50.0%, P = 0.000), lower total cholesterol [TC (mmol/L): 3.97±1.05 vs. 4.43±0.88, P =0.039], and lower low density lipoprotein [LDL (mmol/L): 2.30±0.76 vs. 3.00±0.84, P = 0.000]. Multivariate Logistic regression showed that the use of statins [odds ratio (OR) = 0.222, 95% confidence interval (95%CI) = 0.075-0.658, P =0.007] and the history of cerebrovascular diseases (OR = 0.321, 95%CI = 0.113-0.912, P = 0.033) were protective factors of BHI. Compared with non-TTS subgroup, TTS subgroup had a lower percentage of diabetes history (0% vs. 37.8%, P = 0.002), lower glycated hemoglobin [HbA1c: 0.055 (0.050, 0.056) vs. 0.064 (0.056, 0.075), P = 0.000], higher TC (mmol/L: 4.70±1.16 vs. 3.80±0.95, P = 0.001), first day mean arterial pressure [MAP (mmHg, 1 mmHg = 0.133 kPa):114 (98, 122) vs. 103 (94, 108), P = 0.042], third day diastolic blood pressure [DBP (mmHg): 82 (77, 94) vs. 67 (59, 86), P = 0.002], and third day MAP [mmHg: 106 (95, 114) vs. 94 (80, 106), P = 0.015]. Multivariate Logistic regression analysis showed that increased MAP on the third day of admission was an independent risk factor for TTS (OR = 11.833, 95%CI = 1.113-125.779, P = 0.040), increased HbA1c was protective factor of TTS (OR = 0.022, 95%CI = 0.001-0.345, P = 0.006). The rate of poor outcome at discharge of all the BHI patients were higher than those of the non-BHI patients (34.1% vs. 14.3%, P = 0.045). Conclusions Acute severe stroke patients with high incidence of acquiring BHI and having BHI is associated with poor outcome after discharge. Using statins, ischemic preconditioning and control blood pressure, the occurrence of BHI can be reduced and might be beneficial to patients.

Objective@#To introduce a reconstruction procedure of natural sideburn, with combined expanded retroauricular flap and scalp flap.@*Methods@#A retrospective study was produced in Plastic Surgery Hospital, PUMC, from January 2014 to December 2017. Twenty patients (21 sides) underwent sideburn reconstruction with combined expanded retroauricular flap and scalp flap (double pedicled flap, n=3; single pedicled flap, n=17) were included in this study. There were 12 male (12 sides) and 8 female (9 sides), with the mean age of (23.8±3.2) years. The sideburn defect was caused by burn in 19 patients, and it was resulted from hemangioma in 1 patient.@*Results@#The size of flaps ranges from 8 cm×12 cm to 10 cm×16 cm. Venous congestion at the distal end of the flap occurred in 1 patient, which was cured after dressing change, and the sideburn was not affected. The reconstructed sideburns are natural, symmetric, and without obvious scar. The follow-up time was 3-40 months. Fourteen patients were very satisfied with the reconstructed sideburn, and 6 patients were satisfied. No severe complication was observed during follow-up time.@*Conclusions@#The combined retroauricular flap and scalp flap is an alternative method for sideburn reconstruction, which provide natural hair distribution, inconspicuous scars and less complications.
RESUMEN
Objective@#To explore a surgical method for the reconstruction of naturally dynamic double eyelid by fully reserving orbicularis oculi muscle.@*Methods@#Incisional double eyelid blepharoplasty were performed on 352 patients. Orbicularis oculi muscle in incisional and pretarsal area were completely preserved. Muscle was elevated from plate by resecting deep muscular myolemma and muscles to form pretarsal myocutaneous flap. Thereafter, the orbital septum was completely exposed. The free end of muscle flap was fixed to a higher position of the levator aponeurosis. The orbital septum was repaired at the same time.@*Results@#From June 2009 to December 2017, 352 patients were performed double eyelid blepharoplasty using above technique. They are 337 females and 15 males. Fifty-two patients were followed up for 6-60 months, with the mean time of 27 months. All the incisions were uneventfully healed. The new double eyelid presented smooth appearance, and the so-called " sausage" phenomena were not noticed. There was no concave groove or step-like deformity when eyes closed. Forty-five patients were satisfied with the outcomes. Two patients had shallower supratarsal folds on one side, and 1 patient underwent secondary repair. Two patients complained about asymmetry. Two patients suffered from mild unilateral eyelash eversion (without need of reparation).@*Conclusions@#The combined application of deep and superficial myolemma release of the orbicularis oculi muscle, and orbital septum reset, could create a double eyelid with natural and dynamic appearance.

RESUMEN
The aim of this paper is to reveal the change of the brain function for nicotine addicts after smoking cessation, and explore the basis of neural physiology for the nicotine addicts in the process of smoking cessation. Fourteen subjects, who have a strong dependence on nicotine, have agreed to give up smoking and insist on completing the test, and 11 volunteers were recruited as the controls. The resting state functional magnetic resonance imaging and the regional homogeneity (ReHo) algorithm have been used to study the neural activity before and after smoking cessation. A two factors mixed design was used to investigate within-group effects and between-group effects. After 2 weeks' smoking cessation, the increased ReHo value were exhibited in the brain area of supplementary motor area, paracentral lobule, calcarine, cuneus and lingual gyrus. It suggested that the synchronization of neural activity was enhanced in these brain areas. And between-group interaction effects were appeared in supplementary motor area, paracentral lobule, precentral gyrus, postcentral gyrus, and superior frontal gyrus. The results indicate that the brain function in supplementary motor area of smoking addicts would be enhanced significantly after 2 weeks' smoking cessation.
RESUMEN
Objective The pathogenesis of urinary tract infection and the preventive effect of Bacillus Calmette Guerin on bladder cancer imply the importance of bladder as a unique mucosal surface research. This article discussed that after bladder infected by bacteria,the way in which the microenvironment produce adaptive immunity. Once in the past, bladder is widely considered to be a sterile environment, the concept has been recently shaken. It is suggested that we should further study the influence of urinary tract pathogen infection or BCG immune response. In this paper, bladder biology has been illustrated, and bladder organ immunity is urgently needed to be explored and defined.
