Objective:To investigate the value of implantable cardiac monitor (ICM) in the diagnosis and treatment of patients over 60 years old with unexplained syncope.Methods:This was a multi-center, prospective cohort study. Between June 2018 and April 2021, patients over the age of 60 with unexplained syncope at Beijing Hospital, Fuwai Hospital, Beijing Anzhen Hospital and Puren Hospital were enrolled. Patients were divided into 2 groups based on their decision to receive ICM implantation (implantation group and conventional follow-up group). The endpoint was the recurrence of syncope and cardiogenic syncope as determined by positive cardiac arrhythmia events recorded at the ICM or diagnosed during routine follow-up. Kaplan‐Meier survival analysis was used to compare the differences of cumulative diagnostic rate between the 2 groups. A multivariate Cox regression analysis was performed to determine independent predictors of diagnosis of cardiogenic syncope in patients with unexplained syncope.Results:A total of 198 patients with unexplained syncope, aged (72.9±8.25) years, were followed for 558.0 (296.0,877.0) d, including 98 males (49.5%). There were 100 (50.5%) patients in the implantation group and 98 (49.5%) in the conventional follow-up group. Compared with conventional follow-up group, patients in the implantation group were older, more likely to have comorbidities, had a higher proportion of first degree atrioventricular block indicated by baseline electrocardiogram, and had a lower body mass index (all P<0.05). During the follow-up period, positive cardiac arrhythmia events were recorded in 58 (58.0%) patients in the ICM group. The diagnosis rate (42.0% (42/100) vs. 4.1% (4/98), P<0.001) and the intervention rate (37.0% (37/100) vs. 2.0% (2/98), P<0.001) of cardiogenic syncope in the implantation group were higher than those in the conventional follow-up group (all P<0.001). Kaplan-Meier survival analysis showed that the cumulative diagnostic rate of cardiogenic syncope was significantly higher in the implantation group than in the traditional follow-up group ( HR=11.66, 95% CI 6.49-20.98, log-rank P<0.001). Multivariate analysis indicated that ICM implantation, previous atrial fibrillation, diabetes mellitus or first degree atrioventricular block in baseline electrocardiogram were independent predictors for cardiogenic syncope (all P<0.05). Conclusions:ICM implantation improves the diagnosis and intervention rates in patients with unexplained syncope, and increases diagnostic efficiency in patients with unexplained syncope.

Objective To explore the risk factors of incision complications after cerebral revasculariza-tion.Methods The patients who underwent vascular reconstruction for craniocerebral vascular diseases in the Affiliated Hospital of Xuzhou Medical University who underwent revascularization for cerebrovascular disea-ses from January 2018 to December 2022 were retrospectively included,and the patients were divided into the incision complications group and the no incision complications group.Among them,this study documented the delayed complications following incision healing after cerebral revascularization.The baseline clinical data of patients'demographics and incisional complications after cerebral revascularization were recorded,and possi-ble influencing factors were included in a binary logistic regression analysis to analyze the influencing factors that may contribute to the occurrence of incisional complications after cerebral revascularization.Results A total of 117 patients who underwent cerebral revascularization were included,including 25 cases(21.4％)in the group with incision complications,including 7 cases(28.0％)of fat liquefaction,4 cases(16.0％)of inci-sion dehiscence,7 cases(28.0％)of incision infection,and 7 cases(28.0％)of necrosis,while 92 cases(78.6％)in the group without incisional complications.Univariate analysis showed that there was no statisti-cally significant difference in gender,age,hypertension,hyperlipidemia,smoking,drinking,disease type,and vascular reconstruction type between the patients with incision complications after cerebral revascularization and those without incision complications(P＞0.05).The proportion of patients with diabetes mellitus and the frontal branches of superficial temporal artery not preserved in the incision complications group was higher than in the no incision complications group.BMI,scalp thickness,and operation time in the group with incision complications were higher than those in the no incision complications group,and the difference was statistical-ly significant(P＜0.05).Multifactorial analysis showed that scalp thickness(OR=1.484,95％CI:1.024-2.149,P=0.037),BMI(OR=1.323,95％CI:1.042-1.680,P=0.021),and the absence of the frontal branch of the superficial temporal artery(OR=3.582,95％CI:1.146-11.190,P=0.028),were the main risk factors for incisional complications(P＜0.05).Conclusion BMI,scalp thickness,and failure to preserve the frontal branch of the superficial temporal artery are independent risk factors for scalp incision complica-tions after cerebral revascularization.

Objective:This study aims to discuss the diagnosis and treatment of pediatric appendicovesical fistula (AVF).Methods:A retrospective analysis was conducted on the clinical data of a pediatric patient with AVF admitted to our hospital in March 2023. The patient was a 6-year and 11-month old male who was hospitalized on March 21, 2023, due to difficulty urinating accompanied by diarrhea for two weeks. Computed tomography (CT) revealed bladder stones. The preoperative diagnosis was bladder stones. Transurethral cystoscopic lithotripsy with laser was performed under general anesthesia. Two weeks postoperatively, the child presented with recurrent symptoms of frequent urination, urinary pain, and diarrhea. Urine routine examination indicated a urinary tract infection. Over a month of antibiotic treatment was ineffective, and symptoms such as pneumaturia and fecaluria emerged, with exacerbation of diarrhea, suggesting the possibility of a fistulous tract between the child's intestine and bladder. Further bladder ultrasonography with contrast showed microbubbles of contrast medium leaking from the right posterior bladder wall into the intestinal tract. Enhanced magnetic resonance imaging (MRI) demonstrated a small, sharp tube-like shadow at the upper edge of the right posterior bladder, with a strip-like, significantly enhanced shadow within the lumen. The preoperative diagnosis was revised to appendicovesical fistula. During cystoscopic examination, a papillary-like protrusion was identified on the right lateral wall of the bladder, with no evident orificium fistulae or foreign body discharge noted at the protrusion site. Consequently, robot-assisted laparoscopic partial cystectomy, appendectomy, and lysis of adhesions were performed.Results:The patient was administered antibiotic for a 10-day course of anti-infection and a urinary catheter was maintained for 13 days. The patient recovered entirely and had been discharged after the removal of the urinary catheter. At an 11-month follow-up, there were no reported specific discomforts.Conclusions:Pediatric AVF is rare, and bladder contrast-enhanced ultrasonography and MRI are preferred for initial diagnostic evaluation. The diagnosis can be confirmed by specific clinical presentations such as intermittent pneumaturia and fecaluria, diarrhea with bladder stones. Laparoscopic surgery or robot-assisted laparoscopic surgery could be a feasible treatment option.

Objective To explore the expression and clinical significance of sine oculis homeobox homolog 4(SIX4)in endometrial carcinoma and its effect on the invasion and migration of Ishikawa cells.Methods Real-time quantitative polymerase chain reaction(RT-qPCR)was used to detect the expression level of SIX4 in endometrial carcinoma tissue(endometrial carcinoma group)and normal endometrial tissue(control group).The correlation between the expression level and the clinicopathological characteristics of endometrial carcinoma patients was analyzed.Ishikawa cells were divided into normal group(blank control group),negative control group(transfect-ed with siRNA-NC group)and inhibition group 1(transfected with siRNA-1 group),inhibition group 2(transfected with siRNA-2 group),inhibition group 3(transfected with siRNA-3 group),RT-qPCR was used to detect the expression of SIX4 in each group.Western blot was used to detect the protein expression level of SIX4,E-cadherin and N-cadherin in Ishikawa cells of each group;Tran-swell test and scratch test were used to detect the invasion and migration ability of Ishikawa cells in each group.Results Compared with the control group,the expression level of SIX4 was higher in endometrial carcinoma group(P<0.05).The high expression of SIX4 was correlated with the clinical stage of endometrial carcinoma,the depth of muscular invasion and lymph node metastasis(P<0.05),but not with age,tissue type and differentiation degree(P>0.05).After SIX4 expression was inhibited by siRNA,RT-qPCR showed that inhi-bition group 2 had the best interference effect.Western blot showed that the expression of E-cadherin in inhibition group was higher than that in normal group and negative control group,while the expression of SIX4 and N-cadherin was lower.Transwell and scratch experi-ments showed that the invasion and migration of cells in the inhibition group were significantly lower than those in the normal group and negative control group(P<0.05).Conclusion SIX4 is highly expressed in endometrial carcinoma tissues,and its high expression is related to the adverse pathological features of endometrial carcinoma.siRNA targeted inhibition of SIX4 expression can inhibit the invasion and migration ability of endometrial cancer cells through epithelial mesenchymal transition pathway.

Objective:To explore the clinical characteristics of juvenile-onset ankylosing spondylitis.Methods:Clinical data of 350 cases of ankylosing spondylitis diagnosed in Beijing Jishuitan Hospital from January 2014 to December 2019 were collected. There were 75 cases with the symptom onset in age ≤16 years (juvenile-onset ankylosing spondylitis, JoAS), and 275 cases with the symptom onset in age>16 years (adult-onset ankylosing spondylitis, AoAS). The clinical characteristics of two groups were analyzed.Results:Compared with AoAS, JoAS had a higher proportion of males [98.7% (74/75) vs. 79.6% (219/275); χ 2=15.65, P<0.01] and longer course of disease [11(8,15) vs. 8(4,15) years; Z=-3.09, P<0.01]. Compared with AoAS, JoAS was more prone to have peripheral joint swelling and pain [45.3%(34/75) vs. 18.9%(52/275), χ 2=22.20, P<0.01], hip pain [26.7%(20/75) vs. 15.3%(42/275), χ 2=5.25, P=0.03] or heel pain [9.3%(7/75) vs. 2.9%(8/275), χ 2=5.93, P=0.02] as the first clinical manifestation. Compared with AoAS, JoAS had a higher incidence of radiological hip involvement [77.3%(58/75) vs. 43.3%(119/275), OR=4.71, Wald=25.60, P<0.01], lower bone mineral density than peers [34.7%(26/75) vs. 23.3%(64/275), OR=2.23, Wald=7.20, P<0.01], higher incidence of malnutrition [25.3%(19/75) vs. 13.8%(38/275), OR=2.16, Wald=5.84, P=0.02] and higher incidence of acute uveitis [17.3%(13/75) vs. 6.5%(18/275), OR=2.72, Wald=6.24, P=0.01] after adjusting the course of disease. Conclusion:Compared with adult-onset ankylosing spondylitis, juvenile-onset ankylosing spondylitis is more prone to have peripheral joint swelling or hip pain as the first clinical manifestation; the radiological hip involvement, lower bone mineral density than peers, malnutrition and uveitis are more likely to occur.

Objective To investigate the clinical characteristics of paraneoplastic syndrome with prominent osteoarticular involvement. Methods The clinical materials of 20 patients with paraneoplastic syndrome with prominent osteoarticular involvement were collected. The characteristics of clinical manifest-ations, laboratory tests and imagines were analyzed. Results Among the 20 patients, 16 were male and 4 were female, with a mean age of 44.5 years and a median course of 6 months. Ten cases were associated with hematological tumor and 10 cases were associated with solid tumor. Eleven cases presented as peripheral arthritis (7 cases of polyarthritis, 4 cases of oligoarthritis/monoarthritis), 5 cases presented with hypertrophic osteoarthropathy (HOA) and 4 cases presented with tumor-induced osteomalacia (TIO). Three cases were acute lymphocytic leukemia, 2 cases were multiple myeloma, 1 case was lymphoma, and 1 case was bone tumor in polyarthritis. Four oligoarthritis cases were all associated with acute lymphocytic leukemia. All 5 cases of HOA were associated with lung cancer. All 4 cases of TIO were associated with tumor of mesenchymal tissue. Extra-articular manifestations presented in 14 cases and inflammatory markers increased in 15 cases. anti-cyclic cirullinated peptide (anti-CCP) antibodies was low titer positive in only 1 case and other parameters including rheumatoid factor (RF), anti-CCP antibodies, antinuclear antibodies spectrum (ANAs) and human leukocyte antigen (HLA)-B27 were negative. Multiple bone imaging abnormalities appeared in 15 cases. Conclusion Osteoarticular manifestations may be the first symptom of malignancy and difficult to diagnose. It is necessary to be highly aware of potential malignancy.

BACKGROUND: Thoracoscopic surgery has gradually become the major procedure for lung cancer surgery in our department. Its characteristics are minimal trauma and quick recovery, which make approximately 90% of patients discharge from the hospital after surgery. However, the postoperative complications still happen now and then. We analyzed the patients who had been hospitalized for longer than 7 days after thoracoscopic lung cancer surgery, aiming to summarize the types and risk factors of complications, and improve postoperative safety of patients. METHODS: The data were come from the prospective database of Thoracic Surgery Unit One in Peking Cancer Hospital, and patients that underwent thoracoscopic pulmonary surgery between Jan. 2010 and Dec. 2014 with length of stay more than 7 days were included in the study. The classifications of the complications were investigated and graded as mild or severe complications according to modified Claviengrading, the relationship between clinical factors and degrees of complications was also analyzed. RESULTS: The hospitalization of 115 cases were longer than 7 days after surgery, accounting for 10.3% (115/1,112) of the whole patients that underwent surgery during the same period. Eighty-one cases had mild complications, accounting for 7.3% (81/1,112) of the whole cases that underwent surgery during the same period and 70.4% (81/115) of the cases with prolonged length of stay; the proportions of severe complications in both groups were 3.1% (34/1,112) and 29.6% (34/115), respectively; and the proportions of complications that caused perioperative deaths were 0.18% (2/1112) and 1.7% (2/115), respectively. Among all the postoperative complications, the most common was air leakage for more than 5 days after surgery, with a total of 20 cases (1.8% and 17.4%). The other common complications were: atelectasis (19 cases, 1.7% and 16.5%), pulmonary infection (18 cases, 1.6% and 15.7%), etc. The less common complications was bronchopleural fistula (4 cases, 0.36% and 3.5%) with very high risk, and 2 cases died perioperatively due to the combination of acute respiratory distresssyndrome (ARDS). In the clinical factors, only preoperative low pulmonary function (FEV1%<70%) was the potential risk factor for postoperative severe complications (45.8% vs 23.6%, P=0.038). There was no significant difference either regarding the 5 year disease free survival or the 5 year overall survival between mild complication group and severe complication group, with 5 year DFS being 52.2% and 51.9%, respectively (P=0.894) , and 5 year overall survival being 64.0% and 53.5%, respectively (P=0.673). CONCLUSIONS Continuous postoperative air leakage, atelectasis and pulmonary infections were the major causes for prolonged hospitalization after thoracoscopic surgery for lung cancer, and bronchopleural fistula was the most perilous complications. Patients with low preoperative pulmonary function were more likely to have severe postoperative complication, however, this would not influence the long term survival of the patients.

BACKGROUND: Currently, there is no consensus on the follow-up strategy (follow-up time interval and content) of non-small cell lung cancer (NSCLC) in the world, and the relevant clinical evidence is also very limited. In this study, we aimed to summarize the recurrence/metastasis sites and timings of stage I NSCLC patients based on their follow-up data, aiming to provide a basis of follow-up time interval and content for this group of patients. METHODS: We retrospectively analyzed the 416 stage I NSCLC patients that underwent continuous anatomic lobectomy between Jan. 2000 to Oct. 2013 in our prospective lung cancer database. According to the recurrence/metastasis sites and timings, the long term follow-up time interval and content were explored. RESULTS: The 5-yr disease free survival (DFS) and overall survival (OS) in the whole group were 82.4% and 85.4%, respectively. There were 76 cases (18.3%) had recurrence/metastasis during follow-up, among which the most frequent site was pulmonary metastasis (21 cases, 5.0%), followed by brain metastasis (20 cases, 4.8%), bone metastasis (12 cases, 2.9%), and mediastinal lymph node metastasis (12 cases, 2.9%). Among the factors that could influence recurrence/metastasis, patients with pT2a suffered from a higher recurrence/metastasis rate compared to patients with pT1 (P=0.006), with 5-yr DFS being 73.8% and 87.3%, respectively (P=0.002), and the 5-yr OS being 77.7% and 90.3%, respectively (P=0.011). CONCLUSIONS The commonest recurrence/metastasis sites of stage I NSCLC after anatomic lobectomy are lung, brain and mediastinal lymph nodes, the risk of recurrence/metastasis within 2 years were equal to that between 3 years and 5 years. The follow-up frequencies and content within 2 years could be adjusted according to T stages.

Objective To assess the value of plasma level of cystatin C(Cyst-C)and carotid artery plaque score(PS)in predicting significant coronary artery disease(SCAD)in patients with chest pain. Methods A total of 192 patients with chest pain were involved retrospectively. According to the coronary angiography results ,the patients were divided into groups of SCAD (n = 128) and non-significant coronary artery disease (NSCAD , n = 64). Analyses were done to discuss the association of Cyst-C and PS with SCAD and the predictive value of Cyst-C and PS for SCAD. Results Logistic regression analysis demonstrated that Cyst-C and PS were independent predictors of SCAD. The odds ratios(OR)associated with the Cyst-C(each 1 mg/L)and PS(each 1 mm)for prediction of SCAD were 1.329 and 1.197,respectively. The areas under the receiver-operating characteristic curves(AUC)for the Cyst-C and the PS to predict the SCAD were 0.654 and 0.688,respectively. The combination of Cyst-C and PS increased the AUC to 0.742. The optimal cut-off value of Cyst-C was 0.95 mg/L and had a sensitivity of 72.3% for SCAD. Similarly,the optimal cut-off level of PS was 3mm which presented a sensitivity of 70.7%. A Cyst-C ≥ 0.95 mg/L and a PS ≥ 3 mm had negative predictive values of 46.3% and 48.3%,respectively,for SCAD. By combining Cyst-C with PS ,the sensitivity and negative predictive value increased to 83.6%and 62.5%, respectively. Conclusions Cyst-C and PS are both correlated with SCAD. They are independent predictive factors for SCAD in patients with chest pain. Combination of Cyst-C and PS can improve the predictability ,which may increase the reliability of screening SCAD before cardiac catheterization.

Objective To investigate the effect of group cognitive behavioral therapy on anxiety and depression in patients with chronic heart failure ( CHF ) .Methods One hundred patients with CHF were recruited from January 2012 to December 2013 in cardiovascular department , and were divided into the intervention group and the control group , with 50 patients each .Comprehensive intervention including routine heart failure care and group cognitive behavioral therapy combined with other therapies was adopted on the patients in the intervention group .The Self-rating Anxiety Scale ( SAS ) and the Self-rating Depression Scale ( SDS) were used to compare the difference of anxiety and depression between groups .Results At the baseline, the incidence of anxiety was 25%, within which 11 patients had mild anxiety , and 10 patients had moderate anxiety, and 4 patients had severe anxiety.The incidence of depression was 39%, within which 19 patients had mild depression , and 14 patients had moderate depression , and 6 patients had severe depression .The score of SAS and SDS in the intervention group after intervention were (36.90 ±8.465) and (27.53 ±7.162), respectively, which were significantly lower than (40.91 ±8.019) and (36.78 ±10.562) in the control group (t=9.244,10.335, respectively;P<0.01).Conclusions Group cognitive behavioral therapy can effectively relieve the anxiety and depression in patients with chronic heart failure .
