Objective:To explore the predictive value of uterine artery blood flow parameters of Doppler ultrasound combined with coagulation related indicators on the pregnancy outcome of recurrent abortion caused by thrombophilia.Methods:A total of 82 patients with recurrent abortion who admitted to the department of gynecology outpatient of Beijing Haidian Hospital from January 2020 to January 2023 were selected.All patients received relevant treatment,and the follow-up results were calculated as statistic method.Before treatment on the day after admission,uterine artery pulse index(PI),resistance index(RI),the ratio of the maximum blood flow velocity of systolic pressure(S)to the maximum blood flow velocity of end-diastolic(D)(S/D),and activated partial thromboplastin time(APTT),prothrombin time(PT),fibrinogen(FIB),thrombin time(TT)and D-dimer(D-D)of all patients were detected.Pearson correlation analysis was adopted to analyze the correlations between PI,RI,S/D and each of APTT,PT,FIB,TT and D-D.Receiver operating characteristic(ROC)curve was used to analyze the values of single PI,RI,S/D,APTT,PT,FIB,TT and D-D,and the value of the combined detection of them in predicting the pregnancy outcome of recurrent abortion caused by thrombophilia.Results:Follow up results showed that 49 cases of 82 patients with recurrent abortion were successful pregnancy and 33 cases of them occurred pregnancy loss,and the PI,RI and S/D of pregnant women with successful pregnancy were significantly lower than those of pregnant women who occurred pregnancy loss,with statistical significance(t=10.598,6.693,3.059,P<0.05).The levels of APTT,PT,FIB,TT and D-D of pregnant women with successful pregnancy were significantly lower than those of pregnant women who occurred pregnancy loss,and the differences were statistically significant(t=9.552,96.462,22.767,5.100,95.805,P<0.05),respectively.PI appeared respectively positive correlation with APTT,PT,FIB,TT and D-D(r=3.178,P<0.05),and RI appeared respectively positive correlation with APTT,PT,FIB and D-D(r=3.246,P<0.05),and S/D also appeared respectively positive correlation with PT,FIB,TT and D-D(r=3.246,P<0.05).The sensitivities of single PI,RI,S/D,APTT,PT,FIB,TT and D-D detection,and the combined detection of them were respectively 42.40%,48.50%,39.40%,48.50%,63.60%,72.70%,42.40%,39.40%and 84.80%in predicting the pregnancy outcome of recurrent abortion caused by thrombophilia.The specificities of them were respectively 98.00%,71.40%,55.10%,75.50%,59.20%,71.40%,77.60%,85.70%and 98.80%,and the AUC values of them were respectively 0.674,0.685,0.409,0.646,0.784,0.788,0.566,0.563 and 0.941.Conclusion:Both single and combination of PI,RI and S/D of uterine artery blood flow parameters,as well as APTT,PT,FIB,TT and D-D of coagulation related indicators,have a certain value in predicting pregnancy outcome of recurrent abortion caused by thrombophilia,and the combined detection has higher predictive value.

Objective To investigate the feasibility, safety, and short-term efficacy of minimally invasive McKeown esophagectomy (MIME) in patients with locally advanced thoracic esophageal squamous cell carcinoma (TESCC) after neoadjuvant immunotherapy. Methods The clinical data of the patients with locally advanced TESCC in the First Affiliated Hospital of University of Science and Technology of China from July 2022 to March 2023 were restrospectively analyzed. They were divided into a neoadjuvant immunotherapy (NI) group and a non-neoadjuvant immunotherapy (NNI) group according to different preoperative neoadjuvant therapy. The perioperative clinical data and 3-month follow-up data were compared between the two groups. Results A total of 47 patients were collected, including 31 males and 16 females with a mean age of (67.57±7.64) years. There were 29 patients in the NI group and 18 patients in the NNI group. There were no statistical differences in baseline data, perioperative complications, short-term complications, surgical time, intraoperative bleeding, postoperative adjuvant therapy, metastasis/recurrence within 3 months, R0 resection rate, postoperative pathological staging decline, or College of American Pathologists (CAP) tumor regression grade between the two groups (P＞0.05). Conclusion Neoadjuvant immunotherapy combined with minimally invasive McKeown esophagectomy can be safely and effectively performed for patients with locally advanced TESCC without increasing operation time, intraoperative blood loss and perioperative complications.

Background and objective Cough is one of the main complications after pulmonary surgery,which seriously affects the postoperative quality of life.Preserving the pulmonary branch of vagus nerve may reduce the incidence of postoperative cough.Therefore,the aim of this study was to investigate whether preserving the pulmonary branch of the vagus nerve could reduce the incidence of postoperative chronic cough in patients with stage I peripheral lung adenocarcinoma.Methods A total of 125 patients who underwent single-port thoracoscopic radical resection for lung cancer in the Depart-ment of Thoracic Surgery,The First Affiliated Hospital of University of Science and Technology of China from June 2022 to June 2023 were retrospectively selected,and divided into two groups according to whether the vagopulmonary branch was preserved during the operation,namely,the vagopulmonary branch group(n=61)and the traditional group(n=64).The general clinical data,perioperative conditions,lymph node dissection,Mandarin Chinese version of The Leicester Cough Questionnaire(LCQ-MC)scores before and 8 weeks after operation were recorded in the two groups.Both the two groups were divided into tamponade group and non-tamponade group according to whether autologous fat or gelatin sponge was tamponade after lymph node dissection.LCQ-MC scores and postoperative chronic cough of both groups were calculated.Results The LCQ-MC score of the traditional group was significantly lower than that of the vagopulmonary branch group in physiological,psychological,social and total scores at 8 weeks after surgery,and the difference was statistically significant(P<0.05).There were more cough patients in the traditional group than the vagopulmonary branch group at 8 weeks after surgery,with significant difference(P=0.006).Subgroup analysis was conducted separately for the vagopulmonary branch group and the traditional group.Among the patients in the vagopulmonary branch group and the traditional group,the LCQ-MC scores of the non-tamponade group 8 weeks after surgery were lower than those of the tamponade group(P<0.05).There were more patients with cough in the group 8 weeks after surgery than in the tamponade group(P=0.001,P=0.024).Conclusion For patients with stage I peripheral lung adenocarcinoma,the preservation of the pulmonary branch of vagus nerve is safe and effective,which can reduce the incidence of postoperative chronic cough and improve the postoperative quality of life of the patients.

Objective To investigate the progress of two-dimensional echocardiographic parameters in patients with different severity of aortic stenosis.Methods A retrospective analysis was per-formed on 96 patients diagnosed with aortic stenosis with at least 2 times of transthoracic echo-cardiography(interval ≥1 year)in Department of Cardiology,Fourth Medical Center of Chinese PLA General Hospital from March 2017 to December 2023.According to aortic stenosis severity,they were divided into a mild group(72 cases),a moderate group(14 cases)and a severe group(10 cases).Peak pressure gradient(PPG)across aortic valve,Vmax,mean aortic valve pressure gradient(ΔPm),pulmonary artery systolic pressure(PASP)were collected,and the changes and annual progress of these echocardiographic parameters at baseline and before and after follow-up were analyzed.Results The values of IVST,LVPWT,Vmax,aortic valve PPG and ΔPm were sig-nificantly increased in the mild,moderate and severe stenosis groups in turn(P＜0.05,P＜0.01).The values of Vmax,PPG and ΔPm were significantly lower in the mild stenosis group than the moderate and severe stenosis groups,and the LVPWT value was obviously lower in the mild ste-nosis group than the severe stenosis group(P＜0.05).The aortic valve PPG and ΔPm values at follow-up were significantly higher than those before the follow-up in the three stenosis groups(P＜0.05,P＜0.01).After follow-up,the Vmax values in mild and moderate stenosis groups were notably higher than before(P＜0.01).The PASP value at follow-up was significantly higher than before in the severe stenosis group(P＜0.05).The annual progression rate of Vmax,PASP,LVEF were gradually increased in the mild,moderate,and severe stenosis groups(P＞0.05).The annual progression rate of ΔPm was gradually increased in the three groups in turn(2.30±1.77 mm Hg/year vs 2.40±1.18 mm Hg/year vs 6.08±1.70 mm Hg/year,P＜0.05).Conclusion As the severity of baseline aortic stenosis increases,obvious changes are observed in cardiac structure and function.Before and after follow-up,the serious the aortic stenosis severity is,the faster the annual progression rates of Vmax,PPG,LVEF and PASP are.

Objective:To compare the efficacy and adverse reactions of picosecond and nanosecond Nd∶YAG laser 532 nm in the treatment of seborrheic keratosis.Methods:A total of 30 patients with seborrheic keratosis were enrolled in this study. The rash size was more than 1-2 cm. Half of them were treated with picosecond laser and the other half with nanosecond Q-switched Nd∶YAG laser by wavelength of 532 nm. The treatment effect and adverse reactions were evaluated by observing the area and the disappearance of pigment. The patients were followed up for 3 months after treatment.Results:The total effective rate was 73.33% in the experimental group and 53.33% in the control group, with no significant difference between the two groups ( P>0.05), but the pain score, satisfactory score, scab shedding time and the incidence of pigmentation in the experimental group were lower than those in the control group, and the differences were statistically significant ( P<0.05). Conclusions:The 532 nm picosecond laser has a higher efficiency in treating seborrheic keratosis than 532 nm Q-switched Nd∶YAG, but it has no statistical significance. However, the self satisfaction is higher than that of the control group; the pain score, scab shedding time and the incidence of pigmentation are lower than those of the control group, with statistical significance. Therefore, picosecond 532 nm laser treatment of early seborrheic keratosis is worthy of clinical promotion.

BACKGROUND: Currently, there are many reports on the advantages of three portal video-assisted thoracic surgery (VATS) in the treatment of lung cancer, but there are few reports on the comparison between uniportal and three portal video-assisted thoracic surgery. In this study, we aimed to evaluate the recent curative effect of the postoperative short-term quality of life between uniportal and three portal video-assisted thoracic surgery for non-small cell lung cancer. METHODS: We retrospectively evaluated 266 patients with NSCLC who underwent intended VATS lobectomy by a single surgical team in our ward between January 2016 and August 2017. The general clinical date, perioperative data and short-term life quality were individually compared and analyzed between the two groups. RESULTS: The two groups were similar in terms of clinicopathological features, total number of dissected lymph nodes and nodal stations, postoperative complications and pulmonary complications (P>0.05). Compared with three portal VATS, the intraoperative blood loss, chest tube duration, postoperative thoracic drainage, length of stay and NRS score were significantly decreased in uniportal VATS, with significant differences (P<0.05). CONCLUSIONS As a more minimally invasive surgery, uniportal VATS can be safely and effectively performed for resectable lung cancer, which would achieve even better operation curative effect than three portal VATS.

Objective To observe the impact of minimally invasive Sweet esophagectomy on short term quality of life for patients with Siewert typeⅡesophagogastric junction adenocarcinoma.Methods From January 2015 to September 2017, 60 patients underwent minimally invasive Sweet esophagectomy(MISE group) and 60 patients underwent open sweet esophagecto-my(OSE group).The questionnaires(EORTC QLQ-C30 and QLQ-OES18) were applied to assess the quality of life of the pa-tients before and 1,2,4,8 weeks after operation.The clinicopathologic factors, operational factors and postoperative complica-tions of the two groups were compared by t test and χ2test.The Mann-Whitney test was used to test for statistical significance because the responses were not normally distributed.Results The two groups were similar in terms of clinical characteristics and preoperative QOL scores(P ＞0.05).The MISE group was associated with a significant decrease in surgical blood loss [(88.1 ±32.2)ml vs.(119.5 ±34.1)ml, t＝5.052, P＝0.001], chest tube duration[(8.1 ±4.4)d vs.(10.5 ±4.0)d, t＝3.110, P＝0.002] and postoperative stay[(9.1 ±4.6)d vs.(11.6 ±3.8)d, t＝3.167, P＝0.002] relative to the OSE group.The postoperative in-hospital mortality and total morbidity did not differ between the two groups (P＞0.05).The MISE group was associated with significantly fewer respiratory complications than the OSE group (8.5%vs.22.7%, t＝4.063, P＝ 0.044).The MISE group was associated with a significant increase in hospitalization costs [(54 106 ±4 352) yuan vs. (51 143 ±5 315)yuan, P＝0.001] relative to the OSE group.MISE group gained higher scores in physical function, role func-tion, emotional function, Global QOL and lower scores in pain, fatigue, acid reflux than OSE group after surgery.Conclusion Our minimally invasive technique for Siewert typeⅡesophagogastric junction adenocarcinoma can be safely and effectively performed with favorable early outcomes.Compared to conventional open Sweet approach, MISE impoved the short term quality of life after surgery.

Objective To investigate the correlation between the prognostic nutritional index(PNI) and the clinicopathologic features of patients with non-small cell lung cancer(NSCLC),and to compare postoperative complications and survival between patients with High-PNI(H-PNI) and Low-PNI(L-PNI) after operation.Methods This study retrospectively reviewed and analyzed the medical records of 216 patients underwent surgery between July 2010 and December 2011 who were pathologically dignosed with NSCLC.Among these,127 patients with H-PNI,and 89 patients with L-PNI.The clinicopathologic features,median survival time and 5-year survival rates between two groups were analyzed.Results Patients in the L-PNI group had greater pathologic TNM stage,larger tumors,lower Serum albumin levels,and greater percentage of chemotherapy than those in the H-PNI group(P ＜ 0.05).The H-PNI group was associated with significantly fewer postoperative complications than the L-PNI group (P ＜ 0.05).For the patients with H-PNI,the MST was 61.6 months an the 1-,3-,and 5-year OS were 91.3 ％,80.1％,and 74.1％,respectively.For the patients with L-PNI,the MST was 49.9 months and the 1-,3-,and 5-year OS were 82.0％,63.5％,and 53.5％,respectively.There was significant difference in survival between the two groups(P ＜ 0.05).TNM staging and PNI were showed to be independent prognostic factors.Conclusion Different PNI of NSCLC has certain heterogeneity.Patients with H-PNI show better survival and lower postoperative complications rate than those with L-PNI.

Objective To clarify the applied anatomy of Chinese female breasts,to improve the breast reduction mammoplasty,and to compare the quality of life in women with symptomatic macromastia before and after reduction mammoplasty with the modified round block technique.Methods The blood supply and innervation of the nipple-areolar complex were dissected in 6 Chinese adult females (12 breast specimens).Special attention was paid to the Würinger horizontal septum and the medial and lateral ligaments.The specific beneficial effects of reduction mammoplasty were evaluated with the modified round block technique,and a general questionnaire the Short Form-36 Health Survey Questionnaire (SF-36) was used in this study,which has good reliability and validity.The scores of the patients before and after the surgery were collected respectively.Results In 12 breast specimens,there existed Würinger horizontal septum and the medial and lateral ligaments.The blood supply and nerve innervation of nipple-areolar complex went along Würinger horizontal septum.In all the patients enrolled,SF-36 showed significant higher quality of life after the operation with regard to 7 of 8 investigated domains.Role of emotion increased most significantly.Increased self-esteem and increased personal and public self-consciousness after surgery were observed.Conclusions The incidence of postoperative complications is reduced after using the modified round block technique.Patients have a higher degree of satisfaction overall.These data are further evidence that breast hypertrophy is not solely an esthetic problem.The reduction mammoplasty with the modified round block technique is an ideal technique.

Objective To investigate the regulatory role of rno-miR-30b-5p in the expressions of interleukin-10 (IL-10) and toll-like receptor 4 (TLR4) in uveitis.Methods Both IL-10 and TLR4 gene 3'UTR lucfferase vectors and relevant binding site mutant vectors were constructed.Further,both rno-miR-30b-5p mimics and reporter gene vector were co-transferred into 293 T cells to validate the fluorescent alterations of the reporter gene expression to detect the interactions between rno-miR-30b-5p and the related target genes.Moreover,an experimental autoimmune uveitis (EAU) model was induced with IRBP peptide emulsion in rats,and both lymph node and spleen were isolated on day 12 after EAU induction.In order to measure rno-miR-30b-5p levels and IL-1 0,TLR4 expressions in spleen and lymph node,quantitative PCR and ELISA techniques were applied.Results The results of double lucfferase reporter gene expression analysis showed rno-miR-30b-5p mimic apparently down-regulated the fluorescence intensity of both IL-10 and TLR4 in wild type cells.After the mutation of the target site,the fluorescence intensity of the mutant vector was significantly reduced,accompanied by a significantly statistical difference (all P ＜ 0.01).Moreover,animal results revealed the expressions of rno-miR-30b-5p were apparently decreased,whereas IL-10 and TLR4 were markedly increased in both lymph node and spleen (all P ＜ 0.05).Conclusion Target identification shows that rno-miR-30b-5p can obviously regulate the expressions of 3'UTR gene with either IL-10 or TLR4 gene fragment,though its regulation might not be through the predicted site.The down-regulated expression of rno-miR-30b-5p in both spleen and lymph node in EAU rats result in the up-regulated expressions of both IL-10 and TLR4,further influence the development of uveitis.This study paves a way for the modulation of microRNA on the occurrence and development of uveitis,and will provide a new insight on treating uveitis.
