Objective:To investigate the incidence of venous thromboembolism (VTE) in patients with esophageal cancer (EC).Methods:The retrospective cohort study was conducted. The clinicopathological data of 8 458 EC patients who were admitted to Sichuan Cancer Hospital from January 2017 to December 2021 were collected. There were 6 923 males and 1 535 females, aged (64±9)years. There were 3 187 patients undergoing surgical treatment, and 5 271 cases undergoing non-surgical treatment. Observation indicators: (1) incidence of VTE in EC patients; (2) treatment and outcomes of patients with VTE. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed using the t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was analyzed using the nonparameter rank sum test. Count data were expressed as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test or Fisher exact probability. Comparison of ordinal data was analyzed using the nonparameter rank sum test. Results:(1) Incidence of VTE in EC patients. Of 8 458 EC patients, 175 cases developed VTE, with an incidence rate of 2.069%(175/8 458). Among 175 VTE patients, there were 164 cases of deep venous thrombosis (DVT), 4 cases of pulmonary embolism (PE), 7 cases of DVT and PE. There were 59 surgical patients and 116 non-surgical patients. There was no significant difference in thrombus type between surgical and non-surgical EC patients with VTE ( χ2=1.95, P>0.05). Of 3 187 surgical patients, the incidence of VTE was 1.851%(59/3 187), including an incidence of 0.157%(5/3 187) of PE. PE accounted for 8.475%(5/59) of surgical patients with VTE. Of 5 271 non-surgical patients, the incidence of VTE was 2.201%(116/5 271), including an incidence of 0.114%(6/5 271) of PE. PE accounted for 5.172%(6/116) of non-surgical patients with VTE. There was no significant difference in the incidence of VTE or PE between surgical patients and non-surgical patients ( χ2=1.20, 0.05, P>0.05). (2) Treatment and outcomes of patients with VTE. Among 175 EC patients with VTE, 163 cases underwent drug treatment, and 12 cases did not receive treatment. Among 163 cases with drug therapy, 158 cases underwent anticoagulant therapy, 5 cases were treated with thrombolysis. All the 163 patients were improved and discharged from hospital. Conclusions:The incidence of VTE in patients with EC is relatively low, as 2.069%. There is no significant difference in the incidence of VTE or thrombus type between surgical EC patients and non-surgical EC patients.

Objective:To introduce the application of highly selective arterial indocyanine green angiography (hereinafter referred to as highly selective arterial angiography) in the design of anterolateral thigh free flap.Methods:This study was a retrospective observational study. From November 2023 to April 2024, 29 patients with wounds in extremities which were repaired by anterolateral thigh free flaps designed under the assistance of highly selective arterial angiography and met the inclusion criteria were admitted to the Department of Hand Surgery and Department of Wound Repair Surgery of Suzhou Ruihua Orthopedic Hospital, including 26 males and 3 females, aged 16 to 71 years. The wound area after debridement ranged from 8.0 cm×4.5 cm to 27.0 cm×16.0 cm. During the surgery, highly selective arterial angiography was used to assist in flap design. The fluorescence development range of the source arteries or perforators of flaps was observed. The blood supply range of the source arteries or perforators of flaps was determined based on the fluorescence development of the skin, and the excision position of the flap was adjusted. The flap incision area ranged from 9.0 cm×6.0 cm to 29.0 cm×16.0 cm. During the surgery, the number of highly selective arterial angiography, the type of source artery of perforators for puncture, and changes in the excision position of flaps were observed and recorded. After surgery, the blood supply and survival of flaps, the healing of wounds and the survival of skin grafts in the flap donor sites, and the angiography-related complications were observed.Results:All the 32 flaps of 29 patients were successfully excised. The highly selective arterial angiography was performed 37 times, including 13 cases of puncture of the oblique branch of the lateral circumflex femoral artery, 6 cases of puncture of the descending branch, 8 cases of double puncture of the oblique and descending branches, and 2 cases of puncture of arteries from other branches. During the surgery, the excision position of 28 flaps did not change, the excision position of 3 flaps moved towards proximal extremity of the thigh, and the excision position of 1 flap moved towards distal extremity of the thigh. All the flaps survived successfully after the surgery, and there was no partial necrosis of the flaps at the proximal or distal ends. The wounds in the flap donor sites healed, and all skin grafts survived. No angiography-related complications occurred.Conclusions:Highly selective arterial angiography can be used to determine the blood supply range of the source artery and perforators of the anterolateral thigh free flaps during the surgery. It can evaluate the blood supply of flaps more intuitively and objectively. Its application in assisting flap design can avoid partial flap necrosis caused by unreasonable preoperative design to a certain extent, and it is safe and reliable.

Objective To develop and evaluate the equivalence of the Mandarin test material for tracking of noise tolerance(TNT)test.Methods Six different speech materials were developed(themes including daily life,entertainment,family,festivals,outdoors,and school).Four-minute TNT tests were measured in 21 normal hear-ing subjects using six different test materials.For each session,the tolerable noise level(TNL)and TNT scores were acquired and calculated for 3 time windows(31～240 s,31～120 s,151～240 s).Results Statistic analysis showed significant differences in the TNL(F=43.611,P＜0.05)among the normal hearing listeners.There were statistically significant differences in standardize z-scored TNT scores of the six different materials in the three time windows(P＜0.05).Post-hoc comparisons revealed that all significant differences involved the family and daily life themes.Conclusion Entertainment,festival,outdoors and school themed test materials can serve as the materials of Mandarin tracking of noise tolerance test and can be appied in research and clinical testing.

Objective To evaluate the Mandarin tracking of noise tolerance(TNT)test material and compare the differences between the average tolerable noise level(aTNL)value obtained from assessment and the program-estimated tolerable noise level(eTNL).Methods A total of 25 subjects with normal hearing and aural communica-tional ability were selected to undergo two of the mandarin TNT tests successively(respectively test 1,C1;test 2,C2),and 13 of them completed the third test(C3)under the same test condition as test 2 at least 1 week later.The stimulus for the three test conditions was presented with"speech 0°,continuous noise 180°".Results The aTNL of 25 participants for C1 and C2 was 83.42±3.09 dB SPL and 83.50±3.18 dB SPL,respectively.The eTNL of 25 participants for C1 and C2 were 84.08±3.53 dB SPL and 83.95±3.85 dB SPL,respectively.The aTNL and eT-NL for 13 subjects who participated in C3 was 83.16±2.13 dB SPL and 83.18±2.64 dB SPL,respectively.The intra-session(C1 vs C2)and inter-session(C2 vs C3)test-retest reliability were 2.36 dB and 2.75 dB,respectively.Pearson correlation analysis showed that intra-session(r=0.837,P＜0.001)and inter-session(r=0.867,P＜0.001)test-retest reliability was good.There was no statistical difference between aTNL and eTNL in the other TNT tests(P＞0.05 for both)except that aTNL and eTNL were statistically different in C1(P＜0.01),and more than 90％of the subjects could obtain eTNL within 1 minute.Conclusion The test-retest reliability of Mandarin tracking of noise tolerance test is good,with advantages of high reliability and efficiency.

Autologous ozonized blood transfusion(AOBT) is a therapy of re-transfusion of 100-200 mL of autologous blood after shaking and agitation with appropriate amount of oxygen-ozone in vitro. The oxidation of blood through the strong oxidation of ozone can enhance the non-specific immune response of the body, regulate the internal environment and promote health. This therapy has been increasingly applied in clinical practice, while no unified standard for the operation process in terms of ozone concentration, treatment frequency and treatment course had been established. This operation process of AOBT is primarily explored in order to standardize the operation process and ensure its safety and efficacy.

Objective:To investigate the characteristics and associated factors of depression in elderly patients with Parkinson's disease(PD).Methods:A total of 1138 elderly PD patients from Xuanwu Hospital of Capital Medical University were consecutively enrolled.The Hamilton Depression 17-item Scale(HAMD-17)was used to diagnose depression(scores ≥14). The depressive characteristics of PD patients with depression and those without depression were compared, and Logistic regression model was used to analyze the clinical risk factors of depression in PD patients.Results:Among the 1 138 PD patients, 233 cases had depression.The incidence of depression in PD patients was 20.5%, and the treatment rate was only 6.0%(14 cases). The main symptoms of depression in PD patients included sleep disturbance(101 cases, 43.3%), depression(57 cases, 24.5%), work and interest loss(49 cases, 21%). Compared to PD patients without depression, PD patients with depression were more likely women(49.4% vs36.3%), and had lower cognitive scores[(25.56 ± 4.22)scores vs(27.07 ± 3.08)scores], higher rate of freezing of gait(51.0% vs24.0%), higher incidence of disability(87.1% vs28.5%)( P<0.05). A comparison of each part of the unified Parkinson's disease rating scale(UPDRS)between the two groups revealed that the scores of activities of daily living[(16.52 ± 8.71)scores vs(10.15 ± 5.48)scores], the motor examination[(33.78 ± 19.48)scores vs(22.87 ±13.08)scores]and the complications of therapy[2.0(0.0, 6.0)scores vs0.0(0.0, 2.0)scores]were higher in the PD patients with depression group than in the PD patients without depression group( P<0.05). Logistic regression analysis showed that women( OR=1.532, 95% CI: 1.073-2.187, P=0.019), disability( OR=6.357, 95% CI: 4.399-9.186, P<0.001), activities of daily living evaluated by UPDRS( OR=1.093, 95% CI: 1.043-1.146, P<0.001)and motor complications( OR=1.100, 95% CI: 1.014-1.193, P=0.022)were independent risk factors for PD depression. Conclusions:Depression was common in PD patients and usually manifested as sleep disturbance and low motivation, women, motor complications, disability and decreased quality of daily living were independent risk factors for depression.

Objective    To investigate the prognostic value and consistency of prognostic nutritional index (PNI) and patient-generated subjective global assessment (PG-SGA) in perioperative nutritional status of patients with esophageal cancer. Methods    Clinical data of 224 patients, including 186 males and 38 females with an average age of 63.08±8.42 years, who underwent esophageal cancer surgery in our hospital from November 2017 to August 2018 were retrospectively reviewed. The PNI was calculated according to the results of the first time blood and biochemical tests, and the PG-SGA assessment was also performed. According to the PNI value, the patients were divided into a good nutrition group (PNI≥45, 60 patients) and a malnutrition group (PNI<45, 164 patients). According to the PG-SGA score, the patients were divided into a good nutrition group (PG-SGA<4, 75 patients) and a malnutrition group (PG-SGA≥4, 149 patients). Nutrition-related haematological indexes and body mass index (BMI) were compared between the two groups, and the consistency of PNI and PG-SGA for nutritional assessment was analyzed. Results    The nutrition-related haematological indexes in different PNI groups were statistically different in the perioperative period (P<0.01). The longitudinal changes of prealbumin in patients of different PG-SGA groups were statistically different (P<0.05); the BMI of patients in different PG-SGA groups was statistically different in the perioperative period (P<0.01). The Kappa coefficient of the two indicators was 0.589 (P<0.001). Conclusion    Both PNI and PG-SGA can predict the nutritional risk of patients with esophageal cancer to some extent. PNI is an objective monitoring indicator, and PG-SGA is a subjective evaluation indicator, the combined use of which can more comprehensively reflect and predict the nutritional status of patients, and provide an important reference to the development of individualized nutrition support programs.

Objective To explore the pharmacodynamic action of the extract from raw materials of Rhizoma Anemarrhenae and Cortex Phellode ndri, a classic herb pair in traditional Chinese medicine, on mice with diabetic peripheral neuropathy(DNP). Methods The mice were administrated with intraperitoneal injection of streptozotocin (STZ, 30 mg/kg) and fed with high-fat diet to establish the DNP mouse model. One hundred and sixty male C57BL/6j mice were divided into normal group, model group, metfomin group(130 mg/kg), Xuezhikang group(200 mg/kg), high- and low-dose Rhizoma Anemarrhenae extract group(360, 90 mg/kg) , high-and low-dose Cortex Phellodendri extract group(135, 45 mg/kg), 20 mice in each group. The medication lasted for 24 weeks. On medication week 8, 16 and 24, the plasma levels of glucose (GLU), total cholesterol (TC), triglyceride(TG), low density lipoprotein-cholesterol(LDL-C) and insulin(INS) were determined respectively. On medication week 10, oral glucose tolerance test(OGTT)was carried out. On medication week 24, the plasma nuclear factor kappa B(NF-κB) activity and the plasma levels of transforming growth factor-beta 1(TGF-β1), superoxide dismutase(SOD) and reduced glutathione(GSH) were detected. Results Five weeks after injection of STZ, the body mass of the model group was firstly increased and then decreased, and FBG was increased(P<0.05 compared with the normal group). Compared with the normal group, FBG, TC, TG, LDL-C and INS levels were increased(P<0.01 or P<0.001), plasma NF-κB activity, TGF-β1 and SOD levels were enhanced, and GSH level was decreased in the model group, the difference being statistically significant (P<0.01 or P<0.001). Contrasted with the model group, FBG, TC, TG, LDL-C and INS levels in high-and low-dose Rhizoma Anemarrhenae extract group and in high-and low-dose Cortex Phellodendri extract group were decreased to various degrees. After continuous medication, plasma NF-κB activity and TGF-β1 and SOD levels in high-dose Rhizoma Anemarrhenae extract group and in high-dose Cortex Phellodendri extract group were reduced(P<0.05 or P<0.001), and plasma GSH level was increased(P<0.01). Conclusion Extract from raw materials of Rhizoma Anemarrhenae and Cortex Phellodendri has obvious hypoglycemic effect and protective effect on experimental mice with DPN.

Background and objectiveIt is so far not clear that how myasthenia gravis (MG) affected the prognosis of thymoma patients. The aim of this assay is to compare the postoperative survival between patients with thymoma only and those with both thymoma and MG.MethodsThe Chinese Alliance for Research in Thymomas (ChART) registry recruited patients with thymoma from 18 centers over the country on an intention to treat basis from 1992 to 2012. Two groups were formed according to whether the patient complicated MG. Demographic and clinical data were reviewed, Patients were fol-lowed and their survival status were analyzed.Results There were 1,850 patients included in this study, including 421 with and 1,429 without MG. Complete thymectomy were done in 91.2% patients in MG group and 71.0% in non-MG group (P<0.05). There were more percentage of patients with the histology of thymoma AB, B1, or B2 (P<0.05) in MG group, and more percentage of patients with MG were in Masaoka stage I and II. The 5 year and 10 year OS rates were both higher in MG group (93%vs 88%; 83%vs 81%,P=0.034) respectively. The survival rate was signiifcantly higher in patients with MG when the Masaoka staging was III/IV (P=0.003). Among patients with advanced stage thymoma (stage III, IVa, IVb), the constitu-ent ratios of III, IVa, IVb were similar between MG and Non-MG group. Histologically, however, there were signiifcantly more proportion of AB/B1/B2/B3 in the MG group while there were more C in the non-MG group (P=0.000). Univariate analyses for all patients showed that MG, WHO classiifcation, Masaoka stage, surgical approach, chemotherapy and radiotherapy and resectability were signiifcant factors, and multivariate analysis showed WHO Classiifcation, Masaoka stage, and resectability were strong independent prognostic indicators.ConclusionAlthough MG is not an independent prognostic factor, the sur-vival of patients with thymoma was superior when MG was present, especially in late Masaoka stage patients. Possible reasons included early diagnosis of the tumor, better histologic types, an overall higher R0 resection and less recurrence.
