OBJECTIVE: To investigate the short-term effectiveness of transverse antecubital incision in the treatment of failed closed reduction of Gartland type Ⅲ supracondylar humeral fractures (SHFs) in children. METHODS: Between July 2020 and April 2022, 20 children with Gartland type Ⅲ SHFs who failed in closed reduction were treated with internal and external condylar crossing Kirschner wire fixation through transverse antecubital incision. There were 9 boys and 11 girls with an average age of 3.1 years (range, 1.1-6.0 years). The causes of injuries were fall in 12 cases and fall from height in 8 cases. The time from admission to operation ranged from 7 to 18 hours, with an average of 12.4 hours. The healing of the incision and the occurrence of complications such as nerve injury and cubitus varus were observed after operation; the elbow flexion and extension range of motion after removing the gypsum, after removing the Kirschner wire, and at last follow-up were recorded and compared, as well as the elbow flexion and extension and forearm rotation range of motion at last follow-up between healthy and affected sides; the Baumann angle was measured on the X-ray film, and the fracture healing was observed. At last follow-up, the effectiveness was evaluated according to the Flynn elbow function evaluation criteria. RESULTS: All incisions healed by first intention, and there was no skin necrosis, scar contracture, ulnar nerve injury, and cubitus varus. Postoperative pain occurred in the radial-dorsal thumb in 2 cases. The gypsum was removed and elbow flexion and extension exercises were started at 2-4 weeks (mean, 2.7 weeks) after operation, and the Kirschner wire was removed at 4-5 weeks (mean, 4.3 weeks). All the 20 patients were followed up 6-16 months, with an average of 12.4 months. The fracture healing time was 4-5 weeks, with an average of 4.5 weeks, and there was no complication such as delayed healing and myositis ossificans. The flexion and extension range of motion of the elbow joint gradually improved after operation, and there were significant differences between the time after removing the gypsum, after removing the Kirschner wire, and at last follow-up ( P<0.017). There was no significant difference in the flexion and extension of the elbow joint and the forearm rotation range of motion between the healthy and affected sides at last follow-up ( P>0.05). There was no significant difference in Baumann angle between the time of immediate after operation, after removing the Kirschner wire, and at last follow-up ( P>0.05). According to Flynn elbow function evaluation standard, 16 cases were excellent and 4 cases were good, the excellent and good rate was 100%. CONCLUSION The treatment of Gartland type Ⅲ SHFs in children with failed closed reduction by internal and external condylar crossing Kirschner wire fixation through transverse antecubital incision has the advantages of complete soft tissue hinge behind the fracture for easy reduction and wire fixation, small incision, less complications, fast fracture healing, early functional recovery, reliable reduction and fixation, and can obtain satisfactory results.

Objective:To characterize the histopathological subtypes and their clinicopathological parameters of gender and onset age by common, rare and sparse primary esophageal malignant tumors (PEMT).Methods:A total of 272 437 patients with PEMT were enrolled in this study, and all of the patients were received radical surgery. The clinicopathological information of the patients was obtained from the database established by the State Key Laboratory of Esophageal Cancer Prevention & Treatment from September 1973 to December 2020, which included the clinical treatment, pathological diagnosis and follow-up information of esophagus and gastric cardia cancers. All patients were diagnosed and classified by the criteria of esophageal tumor histopathological diagnosis and classification (2019) of the World Health Organization (WHO). The esophageal tumors, which were not included in the WHO classification, were analyzed separately according to the postoperative pathological diagnosis. The χ 2 test was performed by the SPSS 25.0 software on count data, and the test standard α=0.05. Results:A total of 32 histopathological types were identified in the enrolled PEMT patients, of which 10 subtypes were not included in the WHO classification. According to the frequency, PEMT were divided into common (esophageal squamous cell carcinoma, ESCC, accounting for 97.1%), rare (esophageal adenocarcinoma, EAC, accounting for 2.3%) and sparse (mainly esophageal small cell carcinoma, malignant melanoma, etc., accounting for 0.6%). All the common, rare, and sparse types occurred predominantly in male patients, and the gender difference of rare type was most significant (EAC, male∶ female, 2.67∶1), followed with common type (ESCC, male∶ female, 1.78∶1) and sparse type (male∶ female, 1.71∶1). The common type (ESCC) mainly occurred in the middle thoracic segment (65.2%), while the rare type (EAC) mainly occurred in the lower thoracic segment (56.8%). Among the sparse type, malignant melanoma and malignant fibrous histiocytoma were both predominantly located in the lower thoracic segment (51.7%, 66.7%), and the others were mainly in the middle thoracic segment.Conclusion:ESCC is the most common type among the 32 histopathological types of PEMT, followed by EAC as the rare type, and esophageal small cell carcinoma and malignant melanoma as the major sparse type, and all of which are mainly occur in male patients. The common type of ESCC mainly occur in the middle thoracic segment, while the rare type of EAC mainly in the lower thoracic segment. The mainly sparse type of malignant melanoma and malignant fibrous histiocytoma predominately occur in the lower thoracic segment, and the remaining sparse types mainly occur in the middle thoracic segment.

Objective:To investigate the difference of metabolomics between acute heart failure (AHF) patients and control. To find and validate new metabolic biomarkers.Methods:This was a single-center case-control study which included 89 acute heart failure patients admitted to the emergency department of Henan Provincial People's Hospital from January 2018 to June 2019. Eighty people without heart failure and diastolic dysfunction were enrolled as control group whose age and sex were matched to the study group. The fasting blood samples were collected from femoral arterial. Qualitative and quantitative analyses of plasma metabolites were performed in 2 groups by high performance liquid chromatography tandem mass spectrometry (UHPLC-MS), Orthogonal partial least squares-discriminant analysis (OPLS-DA) model and ROC curve method were applied.Results:Compared with the control group, we found that AHF group had higher likelihood to groups with coronary heart disease (37% vs. 7%, P<0.001), hypertension (58% vs. 28%, P<0.001), diabetes (33% vs. 18%, P=0.033), atrial fibrillation (24% vs. 4%, P<0.001), smoking history (42% vs. 18%, P=0.001), and that AHF group had higher creatinine level [(121.6 ± 78.4) vs. (69.0 ± 21.0), P<0.001], higher urea level [(11.5 ± 7.6) vs. (6.2 ± 2.0), P<0.001], higher heart rate [(92 ± 23) vs. (78 ± 14), P<0.001], hypoproteinemia [(32.4 ± 5 .2) vs. (40.4 ± 2.2), P<0.001], and significantly increased BNP level [(4 200 ± 5 229) vs. (100 ± 68), P<0.001], lower left ventricular ejection fraction[(45 ± 8) vs. (57 ± 6), P<0.001], low serum sodium level ( P<0.001). The metabolites of AHF group were significantly different from those of the control group. The metabolites involved amino acids, fatty acids, lipids, nucleosides and their derivatives. Adenine, N-acetyl-L-glutamic, pseudouridine and Gamma-Glutamylcysteine had certain diagnostic value for AHF comparing to control. The AUC were 0.995, 0.932, 0.920 and 0.900. And the AUC value for BNP diagnosis of AHF is 0.978. Conclusions:There were significant differences in metabolism between AHF group and control group including multiple substances. Adenine, N-acetyl-L-glutamic, pseudouridine and Gamma-Glutamylcysteine has similar diagnostic value compared with BNP for diagnosing AHF.

BACKGROUND: Mortality of lung cancer can be decreased by early screening effectively. However, consistent and proficient standards & methods have not been established in China. This study was based on pulmonary nodules/lung cancer comprehensive management platform established by West China Hospital, Sichuan University. Early screening of pulmonary nodules was integrated into standard healthcare of lung cancer system, aiming to improve survivals of lung cancer patients. METHODS: Three cohorts were established: healthy populations, pulmonary nodules cohort and lung cancer patients cohort, and related clinical data will be collected and analyzed. Preliminary plan includes verifying effect of pulmonary nodules screening module. RESULTS: Pulmonary nodules screening was performed in 2,836 employers (>40 years old) of West China Hospital. Lung cancers were diagnosed in 66 participants, all receiving surgery to remove the lesions. 65 of them were with early stage diseases, 1 with lung cancer and brain metastasis. CONCLUSIONS Proficient screening, follow-up and healthcare can be achieved via pulmonary nodules/lung cancer comprehensive management mode, which will be extended all over west China region in future.

Objective:To evaluate the role of interleukin-6 (IL-6) and CD4 + T-lymphocytopenia in assessing the severity and prognosis of coronavirus disease 2019 (COVID-19). Methods:A prospective observational study was conducted. Forty-five patients with COVID-19 admitted to Henan Provincial People's Hospital from January 13 to March 13, 2020 were enrolled and divided into normal group (13 cases), severe group (20 cases), critically severe group (12 cases) according to the severity of the disease. A total of 15 healthy subjects receiving physical examinations during the same period were collected as the healthy control group. Clinical data were collected to compare the clinical characteristics, general test results, IL-6 and CD4 + T-lymphocytopenia levels of patients in different disease severity groups and healthy control group. The receiver operating characteristic (ROC) curve was drawn to evaluate the predictive value of each indicator for the severity of COVID-19. Multivariate Cox regression analysis was used to analyze the risk factors affecting the prognosis of COVID-19 patients, and Kaplan-Meier survival curve analysis was performed. Results:The age of the critically severe group was significantly higher than that of the severe and normal groups (years old: 66.91±17.01 vs. 59.35±18.07, 40.23±12.61, both P < 0.05), and the negative conversion time of the 2019 novel coronavirus (2019-nCoV) was significantly longer than that of the severe and normal groups (days: 19.00±10.66 vs. 18.00±7.18, 9.31±3.49, both P < 0.05). With the increase of the severity of disease, white blood cell count (WBC), C-reactive protein (CRP), calcitonin (PCT), total bilirubin (TBil), troponin I (TnI), IL-6, D-dimer and other indicators were significantly increased, while lymphocyte count (LYM), platelet count (PLT), CD4 +, CD8 +, oxygenation index (PaO 2/FiO 2) were significantly decreased (all P < 0.01). ROC curve showed that PaO 2/FiO 2, IL-6 and CD4 + had certain predictive value for disease severity of COVID-19, the area under the ROC curve (AUC) of them were 0.903, 0.871, 0.689, and the 95% confidence interval (95% CI) were 0.806-0.949, 0.769-0.974, 0.542-0.853; the best cut-off values were 196.00 mmHg (1 mmHg = 0.133 kPa), 6.02 ng/L, 355 cells/μL, respectively; the sensitivity were 73.3%, 99.3%, 73.3%, and the specificity were 96.6%, 62.1%, 65.5%, respectively. Multivariate Cox regression analysis showed that age, PaO 2/FiO 2, high IL-6 and low CD4 + (IL-6≥6.02 ng/L and CD4 + < 355 cells/μL) were independent risk factors affecting the prognosis of COVID-19 [hazard ratio ( HR) was 1.077, 0.053 and 3.490, respectively, all P < 0.05]. Kaplan-Meier survival analysis showed that when both high IL-6 and low CD4 + (IL-6≥6.02 ng/L and CD4 + < 355 cells/μL) were present, the mean time of adverse prognosis was (20.53±5.71) days; when increased IL-6 and decreased CD4 + were inconsistent, the mean time of adverse prognosis was (53.21±3.16) days. Conclusions:The levels of IL-6 and CD4 + T-lymphocytopenia are closely related to the severity of COVID-19 disease. When IL-6 ≥ 6.02 ng/L and CD4 + < 355 cells/μL occur simultaneously, the prognosis is poor.

Objective To observe the alteration and clinical significances of blood coagulation indicators in patients with lymphoplasmacytic lymphoma (LPL). Methods Twenty patients who were newly diagnosed LPL in the First People's Hospital of Changzhou from January 2008 to October 2017 and twenty healthy controls were studied. The patients were treated by chemotherapy, plasma exchange, supplement of coagulation factor or other supportive therapy. The parameters of prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (FIB), thrombin time (TT), D-dimer (D-D), and platelet count (Plt) were detected in LPL group and healthy controls. Results The levels of PT and APTT in LPL group were dramatically higher than those in control group [(12.9±1.2) s vs. (11.6±0.9) s, (41.7±9.8) s vs. (24.7±2.9) s], and the level of Plt in LPL group was lower than that in control group [112×109/L (3×109/L - 379×109/L) vs. 210×109/L (170×109/L - 271×109/L)], and the differences were statistically significant (all P< 0.05). There were no significant differences in FIB, TT and D-D levels between LPL group and control group (all P ＞0.05). There were no statistical differences in PT, APTT, FIB, TT, D-D and Plt levels among LPL patients with different types of immunoglobins (all P ＞ 0.05). After treatment, all the coagulation abnormalities got relieved and no patient died of hemorrhage or thrombosis. Conclusions The LPL patients have coagulation disorders and hypercoagulability, and this is independent of the type of immunoglobulin. Clinical attention should be paid to monitoring coagulation indicators to prevent the occurrence of adverse reactions.

Objective To explore the role of clinical application of enteral nutrition sequential therapy in early enteral nutrition support by comparison with enteral nutrition non-sequential therapy in critically ill patients with cerebrovascular diseases.Methods A total of 62 patients were randomly (random number) divided into sequential group and conventional (non-sequential) grouThe comparisons of tolerance for enteral nutrition support,levels of prealbumin,the mechanically ventilated time and mortality rate in 28-day between two groups were carried out.Results The tolerance of sequential group was superior to that of conventional group (P＜0.05).The higher level of prealbumin and the shorter mechanical ventilation time were observed in sequential group compared with conventional group (P＜0.01).Compared with conventional group,the patients in sequential group had lower mortality rate in 28 days (P＜0.05).Conclusions Sequential therapy is beneficial to the implementation of early enteral nutrition support in patients with severe cerebrovascular disease,reducing the nutritional adverse events,and improves the prognosis.

Objective To explore the clinical feature,treatment and prognosis of incidental prostate cancer(IPC) after transurethral resection of the prostate (TURP) for benign prostatic hyperplasia (BPH).Methods From January 2009 to April 2017,24 cases undergoing TURP for benign prostatic hyperplasia and being diagnosed with prostate cancer(T1a-T1b) was retrospectivey analysed,who aged from 62 to 84 years (mean 71.8 years).Digital rectal examination (DRE) showed prostate medium texture,smooth surface,and no nodules.Ultrasound presented no low echo nodules in the prostate.Prostate volumes were 19.2-93.4 ml,with median of 40.1 ml.PSA were 1.81-9.11 ng/ml,with median of 4.12 ng/ml.The patients with PSA between 6-10 ng/ml accepted prostate biopsy,and pathological results were negative.Results The The pathology of TURP specimens in 24 cases were diagnosed prostate cancer (21 cases of T1a,3 cases of T1b).According to the new WHO/ISUP classification group,there were 18 cases of hierarchical group 1,3 cases of hierarchical group 2,1 case of hierarchical group 3,2 cases in hierarchical group 4.All patients were treated with hormonal therapy,and 7 cases (5 cases of hierarchical group 1,and 2 cases of hierarchical group 2) underwent laparoscopic radical prostatectomy (LRP) after 3 months of hormonal therapy.The specimens of prostatectomy were examined by whole-mount serial,showing 3 cases of prostate cancer (T1a) with negative margin,and 4 cases of benign prostate cells.They were followed up for 5-82 months with median of 43.5 months.No biological progression or tumor progression was found,and,1 case died of colon cancer after 26 months of follow-up.The patients' age and Gleason score of stage T1b were higher than that of stage T1a.Prostate volume and preoperative PSA had no statistically significant difference between the two stages.Conclusions The patients' age and Gleason score of stage T1b were higher than that of stage T1b.The proportion of residual tumor following TURP was high.The prognosis of incidental prostate cancer was good by hormonal therapy or radical prostatectomy.

Objective The blending instructional teaching mode was used in the obstetrical resi-dent standardization training course and the effect was evaluated. Methods 36 resident physicians who attended obstetrical resident standardization training were chosen as blending instructional teaching group and traditional teaching group, 18 physicians per group. The physicians of blending instructional teaching group received blending instructional teaching mode, which included the obstetrical MOOC and Flipped Class, while the traditional teaching group only took part in the clinical management ruled by the hospital. Staging examination was performed according to the resident physician culture curriculum. Descriptive statistics, t test and chi-square test were performed by SPSS 21.0 lines. Results The average score of theory examination [(93.21±5.40) vs. (81.32±7.10)], practical skill [(89.75±4.70) vs. (68.96±8.20)] and clinical intellectual [(88.64±9.30) vs. (75.88±9.70)] in the blending instructional teaching group was significantly higher than that in the traditional teaching group (P<0.05). The physicians' satisfaction rate of manipulative ability in the blending instructional teaching group was significantly higher than that in the traditional teaching group (72.22% vs. 16.76%), which had statistical significance ( χ2=16.74, P=0.003); The physi- cians' satisfaction rate for the tutor in the blending instructional teaching group was significantly higher than that in the traditional teaching group (83.30% vs. 11.11%), which had statistical significance ( χ2=21.67, P=0.000). Conclusion The blending instructional teaching mode adapts to the development trend of teaching , and improves the effect of obstetrical resident standardization training course.

This study was aimed to assess scales with the unidimensional item response models (UIRM) and classical test theory.The reliability and validity of 841 sub-health status samples were analyzed by CTT.Surveying evaluation from the project perspective was also conducted.The results showed that Cronbach'so coefficients in five areas were all larger than 0.6 with relatively high consistency.The scale structures of five areas were relatively good and the CFI was 0.96.When discriminations of all items were larger than 0.3,the sensitivity of item for its area was high.When the scale test information was 33.8,the accuracy of sub-health status was relatively high.However,there were still some items should be further revised.It was concluded that UIRM can be used to evaluate the psychological measurement performance in the project.It is a supplement to the evaluation result of classical test theory.The reliability and validity of sub-health status scale are relatively high.After IRT correction,it can be used for human-computer interaction techniques “preventive treatment” dynamic monitoring.
