ABSTRACT
@#Objective To compare and analyze the therapeutic effects of robot-assisted lobectomy and segmentectomy for stage ⅠA non-small cell lung cancer with a diameter≤2 cm. Methods A total of 181 patients with pathologically confirmed stage ⅠA non-small cell lung cancer (diameter≤2 cm) who underwent robot-assisted lobectomy and segmentectomy in our hospital from 2018 to 2021 were included. There were 74 males and 107 females with an average age of 57.50±10.60 years. They were divided into two groups according to the surgical procedure: a segmentectomy group (85 patients) and a lobectomy group (96 patients). Results There was no statistically significant difference between the two groups in terms of clinical data such as age, gender, smoking history, basic disease, pathological type, tumour diameter, operative time, postoperative 24 h drainage volume and overall complications (P>0.05). The intraoperative blood loss (33.88±16.26 mL vs. 39.27±19.48 mL, P=0.046), groups of dissected lymph nodes (4.76±1.19 vs. 5.52±1.46, P=0.000), number of dissected lymph nodes (14.81±7.23 vs. 18.06±7.70, P=0.004) and postoperative 72 h drainage volume (561.65±225.31 mL vs. 649.84±324.34 mL, P=0.037) of patients in the segmentectomy were less than those in the lobectomy group. The chest drainage time (5.49±3.92 d vs. 7.60±4.96 d, P=0.002) and postoperative hospital stay time (7.47±4.16 d vs. 9.67±5.50 d, P=0.003) were shorter than those in the lobectomy group. There was no conversion to thoracotomy or perioperative death in the two groups. The postoperative follow-up rate was 100.0% with a longest follow-up time of 48 months. The 3-year recurrence-free survival rates of the segmentectomy group and lobectomy group were 87.7% and 92.4%, respectively (P=0.465). Conclusion The da Vinci robot-assisted lobectomy and segmentectomy are safe and feasible surgical procedures for patients with stage ⅠA non-small cell lung cancer (diameter≤2 cm), with a similar 3-year recurrence-free survival rate. The lobectomy group has more lymph nodes dissected, while the segmentectomy group is superior to the lobectomy group in terms of intraoperative blood loss, postoperative 72 h chest drainage volume, chest drainage time and postoperative hospitalization time.
ABSTRACT

ABSTRACT
@#Objective To compare the postoperative chylothorax outcomes of robot-assisted thoracic surgery (RATS) and video-assisted thoracoscopic surgery (VATS), analyze the risk factors for postoperative chylothorax after minimally invasive radical lung cancer resection and explore possible prevention and control measures. Methods Between June 2012 and September 2020, 1 083 patients underwent minimally invasive pulmonary lobectomy and systematic lymph node dissection in our hospital, including 578 males and 505 females with an average age of 60.6±9.4 years. Patients were divided into two groups according to the operation methods: a RATS group (499 patients) and a VATS group (584 patients). After propensity score matching, 434 patients were included in each group (868 patients in total). Chylothorax and other perioperative indicators were compared between the two groups. Univariate and multivariate logistic regression analyses were performed to identify risk factors for postoperative chylothorax. Results Overall, 24 patients were diagnosed with chylothorax after surgery. Compared with the VATS group, the rate of chylothorax was higher (3.9% vs. 1.6%, P=0.038), the groups and numbers of dissected lymph nodes were more (both P<0.001), and the intraoperative blood loss was significantly less (P<0.001) in the RATS group. There was no statistical difference in the postoperative hospital stay (P=0.256) or chest tube drainage time (P=0.504) between the two groups. Univariate analysis showed that gender (P=0.021), operation approach (P=0.045), smoking (P=0.001) and the groups of dissected lymph nodes (P<0.001) were significantly associated with the development of chylothorax. Multivariate analysis showed that smoking [OR=4.344, 95%CI (1.149, 16.417), P=0.030] and the groups of dissected lymph nodes [OR=1.680, 95%CI (1.221, 2.311), P=0.001] were the independent risk factors for postoperative chylothorax. Conclusion Compared with the VATS, the rate of chylothorax after RATS is higher with more dissected lymph nodes and less blood loss. The incidence of chylothorax after minimally invasive radical lung cancer resection is higher in the patients with increased dissected lymph node groups and smoking history.

ABSTRACT
@#Objective To compare the effect on postoperative immune function between da Vinci robot-assisted thoracoscopic surgery (RATS) and video-assisted thoracoscopic surgery (VATS) , and to provide clinical support for more effective surgical procedures. Methods A total of 90 patients undergoing radical resection of pulmonary carcinoma in our hospital from June to November 2019 were included. There were 49 males and 41 females with an average age of 62.67 (37-84) years. Among them, 50 patients underwent da Vinci robot-assisted thoracoscopic surgery (a RATS group) and 40 patients underwent video-assisted thoracoscopic surgery (a VATS group). The perioperative indexes as well as postoperative inflammatory factors and immune level effects between the two groups were compared. Results Compared with the VATS, RATS could significantly shorten the operation time and decrease intraoperative blood loss (P<0.05). RATS also effectively reduced the increase of postoperative inflammatory factor level (P<0.05). But there was no significant difference in postoperative immune function between the RATS group and the VATS group (P>0.05). Conclusion RATS is superior to VATS in the treatment of non-small cell lung cancer in perioperative indicators and inflammatory factors.
ABSTRACT
@#Objective To explore the factors that affect the drainage time of da Vinci robot lung cancer surgery, to analyze the coping strategies, and to provide a basis for shortening the drainage time of patients after surgery and speeding up the patients' recovery. Methods The clinical data of 131 patients who underwent da Vinci robot lung cancer surgery at the Department of Thoracic Surgery, General Hospital of Northern Theater Command from January 2019 to October 2019 were retrospectively analyzed. Among them, 68 were males and 63 were females, with an average age of 59.84±9.66 years. According to the postoperative thoracic drainage time, the patients were divided into two groups including a group A (drainage time≤ 5 days) and a group B (drainage time >5 days). Univariate analysis and logistic multivariate regression analysis were used to analyze the factors that may affect postoperative drainage time, and the correlation between different influencing factors and thoracic drainage time after da Vinci robot lung cancer surgery. Results Logistic multivariate analysis showed that age≥60 years (P=0.014), diabetes mellitus (P=0.035), operation time≥130 min (P=0.018), number of lymph node dissections≥15 (P=0.002), and preoperative albumin<38.45 g/L (P=0.010) were independent factors affecting the drainage time of da Vinci robot lung cancer surgery. Conclusion For elderly patients with diabetes mellitus during the perioperative period, blood glucose should be actively controlled, reasonable surgical strategies should be formulated to ensure the safety and effectiveness of the operation, while reducing intraoperative damage and shortening the operation time. After the operation, patients should be guided to strengthen active coughing, expectoration and lung expansion. Thereby it can shorten drainage time and speed up the recovery of patients after operation.
ABSTRACT
Purpose@#Gastric cancer (GC) is a malignant tumor with a high mortality rate. Drug resistance is a major obstacle to GC therapy. This study aimed to investigate the role and mechanism of exosomal circPRRX1 in doxorubicin resistance in GC. @*Materials and Methods@#HGC-27 and AGS cells were exposed to different doses of doxorubicin to construct doxorubicin-resistant cell lines. Levels of circPRRX1, miR-3064-5p, and nonreceptor tyrosine phosphatase 14 (PTPN14) were detected by quantitative real-time PCR or Western blot assay. Then, 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide, transwell,and Western blot assays were used to explore the function of circPRRX1 in GC cells. Interactions among circPRRX1, miR-3064-5p,and PTPN14 were confirmed by dual-luciferase reporter assay. The in vivo function of circPRRX1 was analyzed in a xenograft tumor model. @*Results@#CircPRRX1 was highly expressed in doxorubicin-resistant GC cell lines. Knockdown of circPRRX1 reversed doxorubicin resistance in doxorubicin-resistant GC cells. Additionally, extracellular circPRRX1 was carried by exosomes to spread doxorubicin resistance. CircPRRX1 silencing reduced doxorubicin resistance by targeting miR-3064-5p or regulating PTPN14. In GC patients,high levels of circPRRX1 in serum exosomes were associated with poor responses to doxorubicin treatment. Moreover, depletion of circPRRX1 reduced doxorubicin resistance in vivo. @*Conclusion@#CircPRRX1 strengthened doxorubicin resistance by modulating miR-3064-5p/PTPN14 signaling and might be a therapeutic target for GC patients.

ABSTRACT
@#Objective To analyze risk factors for chronic cough after minimally invasive resection of non-small cell lung cancer (NSCLC) and explore the possible prevention measures. Methods A total of 128 NSCLC patients who received minimally invasive resection in 2018 in our hospital were enrolled, including 63 males and 65 females with an average age of 60.82±9.89 years. The patients were allocated into two groups: a robot-assisted thoracic surgery (RATS) group (56 patients) and a video-assisted thoracic surgery (VATS) group (72 patients). Chronic cough was assessed by visual analogue scale (VAS), meanwhile, other perioperative indicators were compared between the two groups. Univariate and multivariate logistic regression analyses were performed to identify risk factors for postoperative chronic cough and explore the prevention strategies. Results Overall, 61 (47.7%) patients were diagnosed with chronic cough after surgery, including 25 (44.6%) patients in the RATS group and 36 (50.0%) patients in the VATS group, and the difference was not statistically significant (P>0.05). Compared with the VATS group, the RATS group got shorter endotracheal intubation time (P=0.009) and less blood loss (P<0.001). The univariate analysis showed that age (P=0.014), range of surgery (P=0.021), number of dissected lymph nodes (P=0.015), preoperative cough (P=0.006), endotracheal intubation time (P=0.004) were the influencing factors for postoperative chronic cough. The multivariate analysis showed that age <57 years (OR=3.006, 95%CI 1.294-6.986, P=0.011), preoperative cough (OR=3.944, 95%CI 4.548-10.048, P=0.004), endotracheal intubation time ≥172 min (OR=2.316, 95%CI 1.027-5.219, P=0.043), lobectomy (OR=2.651, 95%CI 1.052-6.681, P=0.039) were the independent risk factors for chronic cough. Conclusion There is no statistical difference in postoperative chronic cough between the RATS and VATS groups. The RATS group gets less blood loss and shorter endotracheal intubation time. Patients with younger age (<57 years), preoperative cough, lobectomy, and longer duration of endotracheal intubation (≥172 min) are more likely to have chronic cough after surgery.

ABSTRACT
Objective: To investigate the clinical characteristics, imaging features and therapy of lymphocytic hypophysitis (LYH), and to clarify the importance of definitive diagnosis and hormonal therapy. Methods: The clinical materials of a LYH patient diagnosed by the post-operative pathology were collected; combined with the relative literatures, the clinical performance, imageological features and diagnosis and treatment methods were analyzed. Results: The patient was a 28 years old woman with intermittent headache for 2 months and went to hospital. There was no abnormal signs on physical examination. The cephalic MRI results showed the pituitary space-occupying lesions. Relevant examinations including thyroid color Dopplar ultrasound, pituitary thyroid hormone, Gonarelin test and so on were performed. The clinical manifestations, imaging examinations and laboratory examinations suggested pituitary adenomas. The patient underwent transsphenoidal saddle area surgery. The post-operative pathology suggested LYH. After operation, the headache symptom was improved obviously, but the hypopituitarism presented, and the patient was given hormone replacement therapy. It took 3 months for the patient to recover the normal levels of sexual hormones and menstruation. But intermittent headache and hypothyroidism still prestented. Conclusion: It is difficult to distinguish LYH from pituitary adenoma. Pathological biopsy is the gold standard for the diagnosis of LYH. Hypopituitarism may exist after surgical treatment, and long-term hormone replacement therapy should be initiated as needed.
ABSTRACT
Objective Most common infected bacteria were found to analyze their effects on clinical characteristics and 3-year outcome of patients with diabetic foot ulcer ( DFU ) . Methods Materials of cases with positive bacterial culture were selected from DFU patients. 203 cases were infected with the most common 6 strains of mono-bacteria, and 62 cases were infected with multi-bacteria. Data were grouped according to the most common 6 infected bacteria. The outcomes of healing, recurrence, amputation, cardiac events, cerebrovascular events and death were calculated of 3 years after hospitalization. Clinical characteristics of mono-and multi-infected groups and these 6 mono-bacterial infection groups, and risk factors to outcome were analyzed. Results No significant difference was found in baseline clinical characteristics, cardiac and cerebrovascular events, and death during follow-up between mono-and multi-infected groups. The most common 6 infected bacteria were staphylococcus aureus, pseudomonas aeruginosa, proteus, enterococcus faecalis, escherichia coli and klebsiella pneumoniae. Among these groups, there were no significant differences of baseline clinical characteristics and recurrence, cardiac and cerebrovascular events, and death except for the foot ulcer and foot ulcer related prognosis. In staphylococcus aureus infected group, severe lower extremity arterial disease (8.5％), Wagner grade 3-5 (48.9％), moderate and severe infection rate (34.0％) were significantly lower than other groups, and the healing rate ( 93. 6％) was higher than other groups ( all P<0.05). Severe lower extremity arterial disease, cardiac function grading over 3(NYHA), eGFR<60 ml·min-1· (1.73 m2)-1, duration of DFU over 30 days were the main risk factors for ulcers′healing. Wagner grade over 3 was main risk factor for minor amputation. Severe lower extremity arterial disease, Hb<90g/L were the main risk factors for major amputation. Cardiac function grading over 3 ( NYHA ) was main risk factor for cardiac events, and also for death. ALB<30 g/L was main risk factor for death (all P<0.05). Conclusion DFU patients infected with different strains of bacteria were significantly different in foot ulcer and healing rate, while not in cardiac and cerebrovascular events and death.

Objective Secondary infection with pseudomonas aeruginosa( PA) in diabetic foot ulcer( DFU) was analyzed to investigate the related risk factor, antibiotic resistance, and prognoses of the infection. Methods Pathogen cultures were carried out in 966 DFU patients with their clinical data collected. All of the patients were followed-up for two years to observe the outcomes, including ulcer healing, amputation, recurrence of ulcers, non-fatal cardiovascular events, and death. The antibiotic susceptibility, risk factors and associated outcome of secondary PA infection were analyzed. Results Total incidence of PA infection was 13. 0％ in DFU patients, of which 38. 1％was secondary. The susceptibility rates of secondary infected PA to tobramycin, meropenem, eftazidime, levofloxacin, cefepime, and cefepime were similar to those in primary infected PA. However, the susceptibility rates of secondary infected PA to piperacillin, piperacillin/tazobactam, ciprofloxacin, imipenen, gentamicin, aztreonam, and amikacin decreased by 12％ to 22％ as compared with primary infected PA. The healing rate was much lower in patients with secondary PA infection compared with those with primary PA infection, and the accumulated healing rates at2yearswere44.44％ and70.4％ (P=0.01) respectively. Theriskofulcerhealingfailurewithintwoyears increased by 3 folds in patients with secondary PA infection. After adjusting for age, sex, Wagner grade, infection grade, and duration of DFU, plasma albumin level was an independent risk factor for secondary PA infection in patients with DFU(P=0. 001). Conclusions The antibiotics susceptibility rates of secondary infected PA were lower than those of primary infected PA. Secondary PA infection in DFU was less likely to be healed. Plasma albumin level was a risk factor for secondary PA infection.
ABSTRACT
Objective Using Z-score to assess the prevalence of proximal aorta dilatation in middle-aged and aged individuals during routine transthoracic echocardiogram examinations and to identify its risk factors. Methods A total of 823 middle-aged or elderly patients on routine transthoracic echocardiogram examinations were consecutively enrolled. The internal diameters of the sinus of Valsalva (SoV ) and the ascending aorta (AA ) were measured. Z-scores were calculated according to the proposed equation for SoV and AA. A dilated aortic root was defined as a Z-score ≥1.96 or the diameter of SoV or AA ≥ 40 mm. The prevalence of proximal aorta dilatation and associated factors were analyzed. Results The prevalences of proximal aorta dilatation ,SoV dilatation ,and AA dilatation were 26.1%(25/823 ) ,6.0%(49/823 ) ,and 23.7%(195/823 ) , respectively.In the aortic root dilatation group ,age and the proportion of obesity were higher (both P＜0.05) ,and there were more female subjects (30.5% or 117/384 vs.22.3% or 98/439 ,P＜0.01) . The incidences of left atrial dilation ,left ventricular dilation ,left ventricular hypertrophy ,and aortic regurgitation in the aortic root dilatation group were higher than those in the non-aortic root dilatation group(P＜0.05 ) .Logistic regression analysis demonstrated that sex (OR＝ 1.827 ,95% CI :1.248-2.673 ,P＝0.002) ,hypertension (OR＝1.441 ,95% CI :1.000-2.075 ,P＝0.050)and left ventricular hypertrophy (OR＝1.827 ,95% CI :1.248-2.673 ,P＝0.002)were independently correlated with aortic root dilatation. Conclusions The prevalence of proximal aorta dilatation is high in middle-aged and aged individuals. Proximal aorta dilatation is related to sex ,age ,and body size ,and it is often accompanied by structural abnormalities of the heart.
