RESUMEN
BACKGROUND: To determine the utility of virtual-monoenergetic imaging (VMI) at low energy levels from contrast-enhanced dual-layer dual-energy (DLDE) computed tomography enterography (CTE) in the preoperative assessment of internal penetrating lesions of Crohn's disease (CD). MATERIALS AND METHODS: Thirty-eight patients with penetrating lesions of CD by surgery undergoing contrast-enhanced DLDE CTE were retrospectively included. Polyenergetic imaging (PEI) and VMIs at low energy levels [40-70 kiloelectron volts (keV)] with 10 keV intervals were reconstructed. The objective parameters of image quality [noise, signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR)] and the subjective parameter of image quality [diagnostic performance of lesions (DPL), overall image quality(OIQ)] of PEI and all VMIs at the low energy level were compared to determine the VMI on the optimal energy level. The lesion detection capability between PEI and the optimal VMI was compared. RESULTS: VMI40 was determined to be the optimal VMI among all VMIs at the low energy level for owning the best image quality. No significant difference was found in the detecting capability in penetrating lesions between VMI40 and PEI (p = 1.0), whereas a significant difference was found in the detecting capability in the bowel origin of the penetrating lesions (p = 0.004), the involved organ or structure by the fistula (p = 0.016) and the orifice of the fistula connected to the involved organ or structure ( p = 0.031) between them. CONCLUSIONS: Compared to conventional PEI, VMI40 improves the detection capability in anatomical details of penetrating lesions of CD, helping colorectal surgeons rationalizing preoperative plans of internal penetrating lesions of CD.

The relationship between Needle Track Bleeding (NTB) and the occurrence of postoperative immediate pneumothorax remains unclear. In our cross-sectional study, we conducted a retrospective collected of data from 674 consecutive patients who underwent CT-guided percutaneous transthoracic lung biopsies between 2019 and 2022. A logistic regression model was employed to explore the association between NTB and postoperative immediate pneumothorax, and restricted cubic spline curves was used to investigate the link and its explicit curve shape. A sensitivity analysis was performed by transforming the continuous NTB into categorical variable and calculated an E-value. A total of 453 participants (47.90% male) were included in our analysis. The postoperative immediate pneumothorax rate was 41.05% (186/453). We found a negative correlation between NTB and postoperative immediate pneumothorax (OR = 0.91, 95%CI 0.88-0.95) after adjusting for confounding factors. This relationship was nonlinear, with a key inflection point at NTB of 8 mm. No significant link was noted for NTB > 8 mm (OR = 0.98, 95%CI 0.95-1.02), while a protective association was observed for NTB ≤ 8 mm (OR = 0.74, 95%CI 0.66-0.81). NTB showed a nonlinear, protective correlation with postoperative immediate pneumothorax. However, when NTB exceeded 8 mm, the protective association was not observed.

Observational studies have reported a correlation between Helicobacter pylori infection and colorectal cancer (CRC); however, the underlying cause has remained unclear. This research was aimed at determining whether there is a correlation between H. pylori infection and CRC by measuring the prevalence of H. pylori CagA antibodies and VacA antibodies. Using data from many genome-wide association studies (GWAS), we conducted a Mendelian randomization (MR) study with two sample GWAS. Then, we used bidirectional MR to evaluate the association between H. pylori infection and CRC for identifying causation. The most common method of analysis was the inverse variance-weighted technique. In addition, we performed supplementary analyses using the weighted median technique and MR-Egger regression. Horizontal pleiotropic outliers were identified and corrected using the MR Pleiotropy RESidual Sum and Outlier (MR-PRESSO) method. Genetically predicted anti-H. pylori IgG seropositivity was not causally associated with CRC [odds ratio (OR): 1.12; 95% confidence interval (CI): 0.98-1.27, P = 0.08] and neither were H. pylori VacA antibody levels (OR = 0.96, 95% CI: 0.90-1.02, P = 0.25) or H. pylori CagA antibody levels (OR = 1.00, 95% CI: 0.93-1.07, P = 0.92). Furthermore, reverse MR analysis did not reveal evidence for a causal effect of CRC on H. pylori infection. The weighted median, the MR-Egger method, and MR-PRESSO yielded identical results. Using genetic data, MR analysis showed there was no evidence for a causal association between seroprevalence of H. pylori infection and CRC. The relationship between H. pylori infection and CRC requires further research.

PURPOSE@#Robot-assisted technology is a forefront of surgical innovation that improves the accuracy of total knee arthroplasty (TKA). But whether the accuracy of surgery can improve the clinical efficacy still needs further research. The purpose of this study is to perform three-dimensional (3D) analysis in the early postoperative period of patients who received robot-assisted total knee arthroplasty (RATKA), and to study the trend of changes in gait parameters after RATKA and the correlation with the early clinical efficacy.@*METHODS@#Patients who received RATKA in the Center of Joint Surgery, the First Hospital Affiliated to Army Military Medical University from October 2020 to January 2021 were included. The imaging parameters, i.e., hip-knee-ankle angle, lateral distal femoral angle, medial proximal tibial angle, posterior condylar angle were measured 3 months post-TKA. The 3D gait analysis and clinical efficacy by Western Ontario Mac Master University Index (WOMAC) score were performed pre-TKA, 3 and 6 months post-TKA. The differences in spatiotemporal parameters of gait, kinetic parameters, and kinematic parameters of the operated limb and the contralateral limb were compared. The correlation between gait parameters and WOMAC scores was analyzed. Paired sample t-test and Wilcoxon rank-sum test were used to analyze the difference between groups, and Spearman correlation coefficient was used to analyze the correlation.@*RESULTS@#There were 31 patients included in this study, and the imaging indexes showed that all of them returned to normal post-TKA. The WOMAC score at 3 months post-TKA was significantly lower than that pre-TKA, and there was no significant difference between at 3 and 6 months. The 3D gait analysis results showed that the double support time of the operated limb reduced at 3 and 6 months (all p < 0.05), the maximum extension and maximum external rotation of the knee joint increased at stance phase, and the maximum flexion angle, the range of motion and the maximum external rotation increased at swing phase. Compared with the preoperative data, there were significant improvements (all p < 0.05). Compared with the contralateral knee joint, the maximum external rotation of the knee joint at swing phase was smaller than that of the contralateral side, and the maximum flexion and extension moment was greater than that of the contralateral knee. The maximum external rotation moment of the joint was greater than that of the contralateral knee joint (p < 0.05). There was a negative correlation between the single support time pre-TKA and the WOMAC score at 3 months (p = 0.017), and the single support time at 3 months was negatively correlated with the WOMAC score at 6 months (p = 0.043). The cadence at 6 months was negatively correlated with the WOMAC score at 6 months (p = 0.031). The maximum knee extension at stance phase at 6 months was negatively correlated with the WOMAC score at 6 month (p = 0.048). The maximum external rotation at stance phase at 6 months was negatively correlated with the WOMAC score at 6 months (p = 0.024).@*CONCLUSION@#The 3D gait analysis of RATKA patients is more sensitive than WOMAC score in evaluating the clinical efficacy. Trend of changes in gait parameters shows that the knee joint support, flexion and extension function, range of motion, external rotation and varus deformity moment of the patient were significantly improved at 3 months after surgery, and continued to 6 months after surgery. Compared with the contralateral knee, the gait parameters of the operated limb still has significant gaps in functionality, such as the external rotation and flexion and extension. The single support time, cadence, knee extension, and knee external rotation of the operated limb have a greater correlation with the postoperative WOMAC score. Postoperative rehabilitation exercises should be emphasized, which is of great value for improving the early efficacy of RATKA.

BACKGROUND: HIV epidemic among men who have sex with men (MSM) remains a major public health concern in China. Despite a growing body of research on transgender women worldwide, little is known about Chinese transgender women within MSM. We sought to estimate HIV incidence and distinguish risk factors of HIV acquisition among them from that among cisgener (non-transgender) MSM (cis-MSM). METHODS: We conducted an open cohort study among Chinese MSM, including those who were identified as transgender in Shanghai and Tianjin. Participants were initially recruited by local community-based organizations from January to June, 2016, and were followed up approximately every 6 months until June 2018. At each visit, a structured questionnaire was used to gather information on demographics, sexual risk behaviors, and HIV status. HIV incidence was calculated as the number of seroconversions divided by total number of person-years of follow-up among HIV-negatives at baseline. Risk factors of HIV acquisition were assessed by univariate and multivariate Cox regression models with time-dependent variables. RESULTS: A total of 1056 participants contributed 1260.53 person-years (PYs) of follow-up, 33 HIV seroconversions occurred during the follow-up period, yielding an estimated HIV incidence of 2.62 (95% CI 1.80-3.68) per 100 PYs. HIV incidence among transgender women was 4.42 per 100 PYs, which was significantly higher than that of 1.35 per 100 PYs among cis-MSM, demonstrating a threefold higher odds of HIV infection than cis-MSM. For transgender women, those lived locally ≤ 2 years (adjusted hazard ratio [aHR] = 1.76, 95% CI 1.13-2.76) and unprotected anal sex last time (aHR = 4.22, 95% CI 1.82-9.79) were more likely to acquire HIV. For cis-MSM, factors associated with HIV acquisition were frequency of anal sex ≥ 3 times in past one month (aHR = 4.19, 95% CI 1.06-16.47) and unprotected anal sex last time (aHR = 5.33, 95% CI 1.52-18.73). CONCLUSIONS: Compared to cis-MSM, transgender women were at higher risk of HIV acquisition, highlighting an urgent need of tailored prevention. Future HIV program should consider to include them to ensure that this population in China are not left behind.

Total knee arthroplasty (TKA) is an effective treatment for end-stage knee disease, with the postoperative alignment, component position, soft tissue balance, and prosthesis matching being key factors for the success of TKA. In order to achieve more accurate postoperative alignment and component position, better soft tissue balance and prosthesis matching for longer prosthesis longevity, better postoperative function and higher patient satisfaction, various intelligent accuracy technological aids such as computer assisted navigation (CAN), patient specific instrumentation (PSI), surgical robots, microsensors, customized implants (CI) and personalized 3D preoperative planning have emerged and are given high expectation. In this paper, the authors review the application and research progress of the above technological aids mainly from aspects of alignment, component position, clinical outcomes and cost analysis, so as to provide a reference for the application of related technological aids in TKA.
RESUMEN
The distal femoral fracture, tibial plateau fracture and patellar fracture may all develop into traumatic knee arthritis, which is probably associated with knee dysfunction problems. Total knee arthroplasty (TKA) is an effective treatment for end-stage knee arthritis. The distal femoral valgus cut angle (VCA) is an important reference for distal femoral resection in TKA and significantly affects postoperative prosthesis position and lower extremity alignment after TKA. For VCA, the specific methods for definition, measurement methods, clinical application and influencing factors are currently controversial. Hence, the authors review the research progress in the role of VCA in TKA from the above-mentioned four aspects, hoping to provide a reference for accurate preoperative planning and intraoperative performance of TKA.
RESUMEN
Objective: To investigate the relationship between the examined number of lymph nodes at the N1 station and the clinicopathological characteristics and prognosis of patients with pT1-3N0M0 non-small cell lung cancer (NSCLC). Methods: A total of 337 patients with pT1-3N0M0 NSCLC who underwent radical lung cancer surgery at the Provincial Hospital Affiliated to Anhui Medical University from January 2013 to March 2015 were selected. The receiver operating characteristic (ROC) curve analysis was used to determine the optimal cut-off value for predicting 5-year survival in pT1-3N0M0 NSCLC patients by the examined number of lymph nodes at the N1 station. The relationships between the examined number of lymph nodes at the N1 station and the clinicopathological characteristics and prognosis of patients with pT1-3N0M0 NSCLC were analyzed according to the optimal cut-off group. Results: A total of 1 321 lymph nodes at N1 station were examined in 337 patients, with a mean of 3.9 nodes per patient. The median survival time was 42.0 months, with 1-, 3- and 5-year survival rates of 82.2%, 57.1% and 24.9%, respectively. ROC curve analysis showed that the optimal cut-off value of 4.5 lymph nodes examined at the N1 station was used to predict 5-year survival in patients with pT1-3N0M0 NSCLC. After rounding off the number, the number of lymph nodes examined at the N1 station was 5 as the cut-off value, and the patients were divided into the group with <5 lymph nodes examined (212 cases) and the group with ≥5 lymph nodes examined (125 cases). The proportion of patients received adjuvant chemotherapy was 19.2% in the group with ≥5 lymph nodes examined, which was higher than 9.0% in the group with <5 lymph nodes examined (P=0.007), and the differences in other clinicopathological characteristics between the two groups were not statistically significant (P>0.05). The median survival time for patients in the group with <5 lymph nodes examined was 38.0 months, with 1-, 3- and 5-year survival rates of 80.1%, 52.5% and 15.6%, respectively. The median survival time for patients in the group with ≥5 lymph nodes examined was 48.0 months, and the 1-, 3- and 5-year survival rates were 85.6%, 64.0% and 36.0%, respectively. The survival rate of patients in the group with ≥5 lymph nodes examined was better than that in the group with <5 lymph nodes examined (P=0.002). Multifactorial Cox regression analysis showed that T stage (OR=1.408, 95% CI: 1.118-1.670) and the examined number of lymph nodes at N1 station (OR=0.670, 95% CI: 0.526-0.853) were independent influence factors for the prognosis of pT1-3N0M0 NSCLC patients. Conclusion: The examined number of lymph nodes at the N1 station is associated with the prognosis of patients with pT1-3N0M0 NSCLC, and the examination of at least 5 lymph nodes at N1 station at the time of postoperative pathological examination improves the 5-year survival rate of patients.

ObjectiveTo explore the effect of Qingfei Jiangmai decoction (QJD) on the content of mercapturic acids in urine in healthy people amid PM2.5 (particles 2.5 microns or less in size) pollution. MethodA total of 84 healthy students of 18-30 years old in Beijing were recruited and they were randomized into the test group (42 in total, with 1 dropout) and control group (42 in total, with 3 dropouts). During the pollution, the test group and the control group respectively took QJD granules and placebo for 7 days (1 bag/time, 2 times/day), and another 7-day intervention with the same drugs was performed at an interval of 4 weeks. The time-activity patterns were recorded during the intervention. On-line solid phase extraction-liquid chromatography/tandem mass spectrometry (SPE-LC-MS/MS) was performed to detect the content of PM2.5-related metabolites S-phenylmercapturic acid (SPMA), 3-hydroxypropylmercapturic acid (3-HPMA), 3-hydroxy-1-methylpropylmercapturic acid (HMPMA), N-acetyl-S-(2-nitrile ethyl)-L-cysteine (CEMA), and N-acetyl-S-(2-hydroxy ethyl)-L-cysteine (HEMA) in urine before and after intervention. Statistical analysis was followed. ResultThe content of CEMA, HEMA, 3-HPMA, and HMPMA in the test group was all higher after the intervention than before the intervention, with the significant difference in HEMA (P<0.05). After intervention, content of HEMA and SPMA was significantly higher in the test group than in the control group (P<0.05), and the difference in HEMA (Z=-3.614, P<0.01) and HMPMA (Z=-1.988, P<0.05) before and after invention in the test group was significantly larger than that in the control group. After the intervention, HEMA in the test group was significantly higher than that in the control group (F=7.597, P<0.01). ConclusionDuring PM2.5 pollution, QJD can increase the excretion of HEMA, a metabolite of ethylene oxide, in the urine of healthy people in Beijing, and enhance the detoxification process of toxic components in PM2.5, which is of great value in preventing and treating haze-related illnesses.
RESUMEN
BACKGROUND@#The mortality of lung cancer ranks first among all malignant tumors, but there are few studies on the effect of different segmentectomy on lung function in patients with early lung adenocarcinoma. The purpose of this study was to evaluate the degree of lung function preservation and short-term results of preoperative planning combined with fluorescence thoracoscopic precision segmentectomy and traditional segmentectomy in patients with early lung adenocarcinoma.@*METHODS@#From January 1, 2020 to October 31, 2020, 60 patients underwent thoracoscopic segmentectomy in the Department of Thoracic Surgery of the First Affiliated Hospital of University of Science and Technology of China: 30 patients in precision segmentectomy group and 30 patients in traditional segmentectomy group. The clinicopathological features, perioperative data and postoperative pulmonary function of the two groups were compared.@*RESULTS@#The operation time of the precision group was shorter than that of the traditional group, and the difference was statistically significant (P<0.05). The preoperative pulmonary function accuracy group and the traditional group in forced vital capacity (FVC), forced expiratory volume in one second (FEV1) and carbon monoxide diffusing capacity (DLCO) were (3.65±0.63) L vs (3.54±0.64) L, (2.72±0.50) L vs (2.54±0.48) L and (20.36±3.02) mL/mmHg/min vs (19.16±3.18) mL/mmHg/min, respectively. One month after operation, the FVC, FEV1 and DLCO of pulmonary function accuracy group and traditional group were (3.35±0.63) L vs (2.89±0.57) L, (2.39±0.54) L vs (2.09±0.48) L and (17.43±3.10) mL/mmHg/min vs (15.78±2.865) mL/mmHg/min, respectively. Three months after operation, the FVC and DLCO of pulmonary function accuracy group and traditional group were (3.47±0.63) L vs (3.20±0.56) L and (19.38±3.02) mL/mmHg/min vs (17.79±3.21) mL/mmHg/min, respectively.@*CONCLUSIONS@#Preoperative planning combined with fluorescence thoracoscopic precise segmentectomy provides advantages in intersegmental plane recognition, vascular anatomy and postoperative recovery, which significantly shortens the operation time and makes the treatment more accurate.

RESUMEN
OBJECTIVE@#To investigate the status of vaccination in children with human immunodeficiency virus (HIV) infection.@*METHODS@#A questionnaire survey was performed in 148 children in Hunan province, China who were registered in China's Acquired Immune Deficiency Syndrome Comprehensive Response Information Management System up to December 31, 2016 and were aged <15 years at the time of confirmed diagnosis of HIV infection. The information on vaccination, diagnosis of HIV infection, and diagnosis and treatment of related diseases was collected.@*RESULTS@#Of the 148 children with HIV infection, there were 70 boys (47.3%) and 78 girls (52.7%); 140 children had an age of 3.8 (0.2-14.8) years at the time of confirmed diagnosis, and 8 children refused to answer this question. Mother-to-child transmission was found in 133 children (91.7%), blood transmission in 1 child (0.7%), and unknown in 14 children (9.5%). Of the 148 children, 129 (87.2%) received antiviral therapy and 19 (12.8%) did not receive such treatment. The vaccination rates of hepatitis B vaccine, bacille Calmette-Guérin vaccine, poliomyelitis live attenuated vaccine and diphtheria-pertussis-tetanus vaccine ranged from 70.9% to 77.7%, which was significantly lower than the national level (≥97%); the vaccination rates of the other vaccines in the National Immunization Program gradually decreased with age. No severe adverse effects were reported after vaccination.@*CONCLUSIONS@#Mother-to-child transmission is the main route of HIV infection in Chinese children. The diagnosis of children with HIV infection is significantly delayed, with low vaccination rates. Efforts should be made to strengthen early diagnosis, early treatment and vaccination in children with HIV infection, in order to improve their quality of life.

Objective:To analyze the short-and long-term outcomes of elderly patients after esophagectomy by comparing preopera-tive comorbidities, postoperative complications, and survival rates among different age groups. Methods:We retrospectively reviewed the data of 253 patients who underwent esophagectomy from January to December 2010 in The First Affiliated Hospital of University of Science and Technology of China. Eighty-eight (34.8%) patients were aged<60 years (group A), 145 (57.3%) were aged 60-75 years (group B), and 20 (7.9%) were aged≥75 years (group C). The short-and long-term outcomes of the patients were analyzed. Results:There were significant differences in three group of patients with hypertension before operation (P<0.05). There were statistically sig-nificant differences among all complications, major complications, pulmonary infection, arrhythmia, and respiratory insufficiency (P<0.05), except for anastomotic leakage and other complications (P>0.05). The mean follow-up was 50.7 months. The median overall sur-vival and 1-, 3-, and 5-year overall survival rates were 68 months and 98.9%, 86.8%, and 69%, respectively, for group A;61 months and 93.1%, 76.1%, and 51%, respectively, for group B;and 32 months and 63.3%, 46%, and 28.8%, respectively, for group C (P<0.001). The median progression-free survival (PFS) and 1-, 3-, and 5-year PFS rates were 60 months and 98.86%, 85.2%, and 45.5%, respectively, for group A;43 months and 87.6%, 53.1%, and 26.9%, respectively, for group B;and 11 months and 30%, 20%, and 10%, respectively, for group C (P<0.001). The differences in survival rates between groups A and B, A and C, and B and C were statistically significant (P<0.001). The multivariate analysis showed that age and TNM stage IV were independent risk factors for overall survival and PFS (P<0.05). Conclusions:The long-term survival rate decreases significantly in elderly patients with esophageal cancer. In addition, age and advanced pathological stage of tumor are independent risk factors for long-term outcomes.

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.
RESUMEN
BACKGROUND@#Recently, the detectable rate of ground-glass opacity (GGO ) was significantly increased, a appropriate diagnosis before clinic treatment tends to be important for patients with GGO lesions. The aim of this study is to validate the ability of the mean computed tomography (m-CT) value to predict tumor invasiveness, and compared with other measurements such as Max CT value, GGO size, solid size of GGO and C/T ratio (consolid/tumor ratio, C/T) to find out the best measurement to predict tumor invasiveness.@*METHODS@#A retrospective study was conducted of 129 patients who recieved lobectomy and were pathological confirmed as atypical adenomatous pyperplasia (AAH) or clinical stage Ia lung cance in our center between January 2012 and December 2013. Of those 129 patients, the number of patients of AAH, AIS, AIS and invasive adenocarcinoma were 43, 26, 17 and 43, respectively. We defined AAH and AIS as noninvasive cancer (NC), MIA and invasive adenocarcinoma were categorized as invasive cancer(IC). We used receiver operating characteristic (ROC) curve analysis to compare the ability to predict tumor invasiveness between m-CT value, consolidation/tumor ratio, tumor size and solid size of tumor. Multiple logistic regression analyses were performed to determine the independent variables for prediction of pathologic more invasive lung cancer.@*RESULTS@#129 patients were enrolled in our study (59 male and 70 female), the patients were a median age of (62.0±8.6) years (range, 44 to 82 years). The two groups were similar in terms of age, sex, differentiation (P>0.05). ROC curve analysis was performed to determine the appropriate cutoff value and area under the cure (AUC). The cutoff value of solid tumor size, tumor size, C/T ratio, m-CT value and Max CT value were 9.4 mm, 15.3 mm, 47.5%, -469.0 HU and -35.0 HU, respectively. The AUC of those variate were 0.89, 0.79, 0.82, 0.90, 0.85, respectively. When compared the clinical and radiologic data between two groups, we found the IC group was strongly associated with a high m-CT value, high Max CT value, high C/T ratio and large tumor size. Gender, solid tumor size, tumor size, C/T ratio, m-CT value and MaxCT value were selected factor for multivariate analysis, when using the preoperatively determined variables to predict the tumor invasiveness, revealed that tumor size, C/T ratio, m-CT value and Max CT value were independent predictive factors of IC.@*CONCLUSIONS@#The musurements of Max CT value, GGO size, solid size of GGO and C/T ratio were significantly correlated with tumor invasiveness, and the evaluation of m-CT value is most useful musurement in predicting more invasive lung cancer.

BACKGROUND@#Through the comparative analysis of the acute and chronic pain postoperative between the single port and triple port video-assisted thoracic surgery to seek the better method which can reduce the incidence of acute and chronic pain in patients with lung cancer.@*METHODS@#Data of 232 patients who underwent single port -VATS (n=131) or triple port VATS (n=101) for non-small cell lung cancer (NSCLC) on January 1, 2016 to June 30, 2017 in our hospital were analyzed. The clinical and operative data were assessed, numeric rating scale (NRS) was used to evaluate the mean pain score on the 1th, 2th, 3th, 7th, 14th days, 3th months and 6th months postoperative.@*RESULTS@#Both groups were similar in clinical characteristics, there were no perioperative death in two groups. In the 1th, 2th, 7th, 14th days and 3th, 6th months postoperative, the NRS score of the single port group was superior, and the difference was significant compared with the triple port (P0.05). Univariate and multivariate analysis of the occurrence on the chronic pain showed that the operation time, surgical procedure and the 14th NRS score were risk factors for chronic pain (P<0.05).@*CONCLUSIONS@#The single port thoracoscopic surgery has an advantage in the incidence of acute and chronic pain in patients with non-small cell lung cancer. Shorter operative time can reduce the occurrence of chronic pain. The 14th day NRS score is a risk factor for chronic pain postoperative.

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.

BACKGROUND@#Previous studies have shown that the neutrophil-to-lymphocyte ratio (NLR) has a significant impact on the prognosis of many malignant tumors such as gastric cancer, colorectal cancer and pancreatic cancer, but the study on the prognosis of patients with resectable lung adenocarcinoma is less. The aim of this study is to investigate the correlation between the NLR and the clinicopathologic features of adenocarcinoma of lung patients who underwent radical pneumonectomy. Furthermore, this study aimed to clarify the predictive and prognostic significance of NLR in patients who underwent pneumonectomy for lung adenocarcinoma.@*METHODS@#This study reviewed the medical records of 163 patients with lung adenocarcinoma who underwent pneumonectomy. The receiver operating characteristic (ROC) curve and Youden index were used to determine the cut-off value of the NLR. Survival curves were described by Kaplan-Meier method and compared by Log-rank test. The univariate and multivariate analyses were performed with the Cox proportional hazard model to identify the prognostic factors.@*RESULTS@#When the NLR value was 2.96, the Youden index was maximal, with a sensitivity of 77.5% and a specificity of 75.9%. The 5-year survival rate in the low NLR group was higher than that in the high NLR group (P<0.05). The univariate and multivariate analyses showed that TNM staging and NLR were independent factors in predicting survival rate.@*CONCLUSIONS@#The NLR value was a simple and useful tool to predict the prognosis of lung adenocarcinoma after radical pneumonectomy.
