Objective To investigate the diagnostic value Tamm-Horsfall protein(THP)and osteopontin(OPN)in serum and 24-hour urine for urolithiasis.Methods A total of 101 patients with urolithiasis who underwent flexible ureteroscopy lithotripsy at the Urology Department of Civil Aviation General Hospital from April 2020 to March 2023 were included as the stone group,and 50 healthy individuals were enrolled as the control group.The samples of serum and 24-hour urine samples were collected from both the groups,and the levels of THP and OPN were measured using enzyme-linked immunosorbent assay(ELISA).Logistic regression analysis was performed to evaluate the association between each biomarker and urolithiasis,and receiver operating characteristic(ROC)curves were plotted to assess their diagnostic value.Results The stone group showed significantly lower THP levels(20.13[13.12,26.03]mg/d)and OPN levels(51.24[36.72,101.37]μg/d)in 24-hour urine,and THP levels(182.01[160.91,209.20]ng/mL)and OPN lev-els(18.76[15.72,22.48]ng/mL)in serum compared to the control group(all the P＜0.001).Binary Logistic regression analysis re-vealed that THP(OR=0.736,95％CI:0.606-0.895),OPN(OR=0.975,95％CI:0.958-0.993)and citrate(OR=0.067,95％CI:0.012-0.376)in 24-hour urine,and THP(OR=0.946,95％CI:0.908-0.986)and OPN(OR=0.896,95％CI:0.803-0.999)in ser-um were the protective factors for urolithiasis,while calcium level(OR=2.125,95％CI:1.243-3.633)24-hour urine was a risk factor(all the P＜0.05).ROC curve analysis showed that the areas under the curve(AUCROC)for the individual diagnosis of urolithiasis were 0.846,0.809,0.786,0.823,0.748,and 0.755 for the above six biomarkers,respectively.The AUCROC for the combined diagnosis u-sing THP+OPN in serum,THP+OPN in 24-hour urine and all the six biomarkers were 0.882,0.920 and 0.984,respectively,indica-ting better diagnostic performance.Conclusion The combined detection of the THP and OPN levels in serum and 24-hour urine may have good diagnostic value for urolithiasis and serve as potential diagnostic biomarkers.

Objective:To investigate the treatment strategy for pediatric humeral supracondylar fractures with callus formation and displacement neglected for over 1 week.Methods:A retrospective analysis was made of the clinical data of 36 children who had been treated at Department of Pediatric Orthopaedics, Medical Center, The Second Affiliated Hospital, Inner Mongolia Medical University from January 2011 to January 2021 for humeral supracondylar fractures with callus formation and displacement neglected for over 1 week. There were 22 boys and 14 girls, with an age of (6.7±2.7) years (from 2.3 to 12.8 years). All fractures were Gartland type Ⅲ. The patients were divided into 2 groups according to their treatment methods: a closed reduction and percutaneous pinning (CRPP) group of 15 patients subjected to the CRPP treatment only, and a leverage group of 21 patients subjected to CRPP assisted by the "lever technique" with posterior elbow Kirschner wire prying and pulling. The 2 groups were compared in terms of operation time, fluoroscopy frequency, quality of reduction, and recovery time for elbow range of motion; the elbow range of motion, visual analogue scale (VAS), Mayo elbow performance score (MEPS) and complications were assessed at the last follow-up.Results:The 2 groups were comparable because there was no significant difference between them in the general information before operation ( P>0.05). All patients were followed up for (26.2±16.3) months (from 6 to 96 months). All the fractures obtained acceptable reduction and clinical union 4 to 6 weeks after operation. The operation time [(28.2±6.8) min] and fluoroscopy frequency [(27.0±6.0) times] in the leverage group were significantly less than those in the CRPP group [(40.8±10.8) min and (43.3±11.4) times] ( P<0.05). The CRPP group was significantly better than the leverage group in the intraoperative Baumann angle (78.1°±1.6° versus 73.7°±4.1°), lateral capitellohumeral angle (58.3°±2.6° versus 49.6°±5.2°) and horizontal rotation rate (109.5%±3.0% versus 103.2%±4.9%) ( P<0.05). The intraoperative reduction in the CRPP group was significantly closer to the normal mean value than that in the leverage group ( P<0.05). There was no significant difference in the recovery time for elbow range of motion between the CRPP and the leverage groups ( P>0.05). At the last follow-up, the Baumann angle (75.4°±2.8°) and the lateral capitellohumeral angle (53.2°±3.6°) in the leverage group were still significantly better than those in the CRPP group (78.3°±1.5° and 57.5°±2.3°) ( P<0.05). However, there was no significant difference in the elbow range of motion, VAS, MEPS or incidence of complications between the 2 groups ( P>0.05). Conclusion:To treat humeral supracondylar fractures with callus formation and displacement neglected for over 1 week in children, CRPP assisted by the "lever technique" with posterior elbow Kirschner wire prying and pulling is an efficient and accurate method, because it can lead to more satisfactory reduction than CRPP only.

Objective:To explore the clinical effect of observation and psychological intervention, splint or brace fixation as well as surgical treatment on habitual dislocation of the hip (HDH) and to combine the authors' data with a compilation of the cases from the literature, evaluingating the epidemiological characteristics of HDH and the treatment scheme to maintain the stability of hip joint by systematic literature review in children.Methods:A retrospective analysis of the relevant data of 11 patients (12 hips) with HDH were treated from March 2007 to March 2021, including 2 boys and 9 girls. The age of the first dislocation was 2.25 (1.66, 3.75) years old and 4.33 (3.33, 6.17) years old at the age of diagnosis. At the same time, the relevant literature reports were searched from 1932 to 2022, and 24 HDH patients reports and clinical studies were confirmed to be included in this study according to the inclusion and exclusion criteria. The data of 33 patients (38 hips) with HDH who were obtained in the literature, including 5 boys and 28 girls. The age of the first dislocation was 2.00 (1.50, 2.00) years old and 4.00 (2.55, 5.00) years old at the age of diagnosis. A total of 44 patients (50 hips) with HDH who were analyzed, including gender, age of first dislocation, age of diagnosis, mode of stimulating dislocation, side and direction of dislocation, accompanying symptoms, family history, trauma history and imaging examination. The data of 41 patients with HDH (3 patients were excluded due to lack of treatment description) were treated with observation and psychological intervention in 19 patients, splint or brace fixation in 13 patients, and surgical treatment in 9 patients. The femoral neck-stem angle, acetabular index, central edge angle (CE angle) and Reimers instability index were measured by AutoCAD software, and the hip function was evaluated by Harris standard. Meantime, the disappearance time of dislocation was recorded.Results:The average follow-up time of 44 patients (50 hips) with HDH were 4.05±2.93 years old, and the time of disappearance of dislocation after treatment were 1.28±1.19 years old. Patients were diagnosed as 7 boys and 37 girls, 30 right and 8 left as well as 6 bilateral, the age of the first dislocation was 2.64±1.54 years old and 4.52±2.64 years old at the age of diagnosis. The data of 39 patients took hip flexion, adduction, internal rotation or hip flexion and adduction as the mode of stimulating dislocation. There were 43 patients with posterior dislocation, 41 patients with an audible "click" sound during dislocation, 36 patients with painless dislocation, and 37 patients with "vacuum phenomenon" were captured at the moment of dislocation. All patients with HDH had no specific family history and obvious history of trauma. There was no significant difference in general data between observation and psychological intervention group, splint or brace fixation group as well as surgical treatment group ( P>0.05). Harris standard to evaluate hip function, CE angle and Reimers instability index of the affected side were significantly different from those before and after treatment at the moment of dislocation ( H=127.51, P<0.001; H=55.70, P<0.001; H=54.69, P<0.001). Compared with the immediate disappearance of dislocation in the surgical treatment group, the disappearance time of dislocation in the observation and psychological intervention group and the splint or brace fixation group were significantly longer, and the difference was statistically significant ( H=20.83, P<0.001). Conclusion:Without specific family history and obvious trauma at young girls, painless posterior dislocation of hip with an audible "click" sound and "vacuum phenomenon" at the moment of dislocation are the significant epidemiological characteristics of HDH. Observation and psychological intervention, splint or brace fixation are recommended as the initial treatment scheme. When conservative treatment is ineffective, surgical treatment is needed to stabilize the hip joint quickly.

Objective:To explore the application of the the anterolateral thigh flap (ALTF) with vascularized fascia lata in repairing large lower lip defects.Methods:From January 2013 to June 2020, the clinical data of the cases with large complex lower lip defect due to extensive resection of lip tumor treated in the Department of Oral and Maxillofacial-Head and Neck Oncology, Shanghai Ninth People’s Hospital, Shanghai Jiao Tong University School of Medicine were analyzed retrospectively. The patients were immediately reconstructed using ALTF with vascularized fascia lata. The flap was used for shape reconstruction, and the fascia lata with residual orbicularis muscle was used for functional reconstruction via simulating the "closed-loop structure" of orbicularis. All these patients were followed up by regular visit. The survival of flap, mouth opening and closing were recorded.Results:All the 4 patients were successfully repaired through the above methods. The ALTF area was 18 cm×7 cm-26 cm×8 cm, with (5-8) cm ×1 cm fascia lata at both sides of the flap. The survival rate of ALTF was 100%. After 6-80 months’ follow-up, the ALTF was in good shape, and the mouth opening degree was 2-3 fingers. When the mouth was closed, the upper and lower lip could be sealed completely, and the drinking water is basically watertight.Conclusions:The shape and dynamic reconstruction could be completed in large complex lower lip defects through ALTF with vascularized fascia lata. The clinical effects were satisfying, and it’s an ideal option for repairing large complex lower lip defects.

Lung cancer is one of the most common malignancies with the highest incidence rate and mortality rate worldwide, and non-small cell lung cancer (NSCLC) accounts for about 85%. Only 5% NSCLC patients are anaplastic lymphoma kinase (ALK) rearrangement positive NSCLC, but the prognosis of these patients is poor, and treatment is urgent. Ensartinib (X-396), a next-generation ALK tyrosine kinase inhibitor (ALK-TKI), has shown greater potency on inhibiting ALK activity and controlling brain metastases than crizotinib, which is indicated for the treatment of crizotinib-resistant, ALK-positive NSCLC patients. Several phase I to III clinical trials included both healthy volunteers and NSCLC patients have been conducted both in China and abroad. In this review, we briefly summarized the results of these trials, and preliminary efficacy, safety, pharmacology and pharmacokinetics/pharmacodynamics of ensartinib were discussed.

Objective:Compared with closed reduction and percutaneous pinning (CRPP) treatment, evaluating the clinical observation of utilizing a transolecranon pin joystick technique combined with CRPP in the teatment of multidirectionally unstable supracondylar humeral fractures in children.Methods:From thirty nine pediatric multidirectionally unstable supracondylar humeral fractures hospitalized between January 2012 and January 2019, twenty seven males (69.23%) and twelve females (30.77%) were included in the study, with a average age of 6.68±2.52 years (range, 2.17-13.75 y), twenty three fractures (65.7%) were treated with CRPP (CRPP group) and the remaining Sixteen fractures (41.03%) were treated utilizing a transolecranon pin joystick technique combined with CRPP (joystick group). Both groups were followed over 16 weeks. The paired sample t test or χ2 test and Fisher's exact test were used to compare the surgical time, times of fluoroscopy, quality of reduction and neurological or vascular complications, Baumann angle, carrying angle, lateralcapitellohumeral angle, postoperative range of motion as well as function-al outcomeduringthe Sixteen weeks and the last follow-up appointment. Results:All caseswere followed up for 1.98±1.43 years, and all fractures achieved clinical healing at 4 to 6 weeks postoperation. The surgical time and times of fluoroscopy were significantly shorter for patients in the joystick group (27.17±9.68 min, 24.25±5.92 times) when compared with CRPP group (48.59±15.75 min, 49.65±23.83 times, P<0.05). All cases showed restoration of the normal lateral capitellohumeral angle. Compared with Baumann angle of normal contralateral upper extremity during the sixteen weeks and the last follow-up appointment, the quality of reduction on the anteroposterior radiographic view was significantly better for patients in the joystick group than that of CRPP group ( P<0.05). The Baumann angle of the affected upper extremity was 77.70°±2.16°, and that of the normal contralateral upper extremity was 73.78°±4.04° in the CRPP group, joystick group was 73.06°±1.81° and 72.81°±3.45°, respectively at the sixteen weeks follow-up. The Baumann angle of the affected upper extremity was 77.13°±2.20°, and that of the normal contralateral upper extremity was 74.17°±4.17° in the CRPP group, joystick group was 72.69°±1.70° and 73.38°±3.48°, respectively at the last follow-up. The range of motion and clinical outcomes based on the criteria of Flynn were similar in both groups ( P<0.05). The elbow joint function of excellent and good rate of the criteria of Flynn was 82.61%, elbow flexion was 134.13°±8.61°, elbow extension was -3.48°±6.47° in the CRPP group, joystick group was 81.25%, 132.19°±9.48° and -3.44°± 4.37°, respectively at the sixteen weeks follow-up. The elbow joint function of excellent and good rate of the criteria of Flynn was 91.30%, elbow flexion was 140.14°±5.76°, elbow extension was -0.65±3.79° in the CRPP group, joystick group was 93.75%, 141.88°±5.12° and -0.31°±3.86°, respectivelyat the last follow-up. No immediate postoperative complications were observed. Conclusion:A transolecranon pin joystick technique combined with CRPP is a safe and effective method, can decrease surgical time and times of fluoroscopy and improve quality of reduction with no increasing risk of complications for closed reduction of multidirectionally unstable supracondylar humeral fractures in children.

The liver is the metabolic center of mammalian body. Systematic study on liver's proteome expression under different physiological and pathological conditions helps us understand the functional mechanisms of the liver. With the rapid development of liquid chromatography tandem mass spectrometry technique, numerous studies on liver physiology and pathology features produced a large number of proteomics data. In this paper, 834 proteomics experiments of mouse liver were systematically collected and the mouse liver proteome database (Mouse Liver Portal, http://mouseliver.com) was established. The Mouse Liver Portal contains the liver's proteomics data under different physiology and pathology conditions, such as different gender, age, circadian rhythm, cell type and different phase of partial hepatectomy, non-alcoholic fatty liver. This portal provides the changes in proteins' expression in different conditions of the liver, differently expressed proteins and the biological processes which they are involved in, potential signal transduction and regulatory networks. As the most comprehensive mouse liver proteome database, it can provide important resources and clues for liver biology research.

Objective To quantitative evaluate the myocardial microcirculation dysfunction in patients with end-stage renal disease (ESRD),and to provide the imaging characteristic for early detection myocardial dysfunction and microcirculation damage in the ESRD patients after dialysis therapy.Methods Sixty-seven patients with ESRD and 1 9 healthy subj ects were enrolled in our study, and the ESRD patients were divided into two groups including patients with preserved systolic function (n=51,EF≥50%)and patients with impaired systolic function (n=16,EF＜50%).The LV regional myocardial perfusion parameters were analyzed including upslope, time to maximum signal intensity (TTM)and max signal intensity (Max SI).Those continuous variables were compared using one-way analysis of variance (A N OVA )in all three groups.Results Compared with the controls and the ESRD patients with preserved EF,the ESRD patients with impaired EF had a significantly lower SV and markedly increased LV mass (all P＜0.001).For the fist-pass perfusion analysis,first-pass perfusion Max SI of all segments were significantly reduced in the ESRD patients with preserved/impaired EF compared with the normal subjects (all P＜0.05).Compared with the ESRD patients with preserved EF and controls,the ESRD patients with impaired EF had lower upslope in the basal segment (P＜0.05).And the ESRD patients with preserved/impaired EF had shorter TTM in the apical segment than that in normal controls (P＜0.01).Conclusion The CMR first-pass perfusion can detect the myocardial deformation and dysfunction in ESRD patients,the Max SI may be more valuable to early detect myocardial microcirculation dysfunction.

OBJECTIVETo screen the allergens in patients with allergic rhinitis (AR) in Yibin, Zhaotong and some areas of the Changjiang River, and to study the distribution characteristics of inhaled allergens. METHODSThe clinical data of 661 patients with allergic rhinitis who diagnosed by skin prick test from March 2013 to June 2015 in the First people's Hospital of Yibin City were studied.RESULTSIn 661 patients, the top 5 allergens and their positive rates of skin prick test were Dermatophagoides farinae (76.5%), house dust mites (72.01%), Roach (35.85%), cat hair (11.35%) and dog hair (8.62%) respectively. There were no statistical difference of the positive rates of allergens among different seasons (χ2=4.568, 0.206). With the increasing age of the patients, the positive rate of allergens was decreased. CONCLUSION The dominated allergens in patients with AR are dust mites, house dust mites and cockroaches in Yibin, Zhaotong and and some areas of the Changjiang River. The prevention and control of AR in children should be toke more attention.
