Objective:To explore the risk factors related to delayed pleural effusion in multiple trauma patients.Methods:A retrospective cohort study was conducted to analyze the clinical data of 145 multiple trauma patients admitted to the First Affiliated Hospital of Soochow University from January 2022 to October 2023, including 99 males and 46 females, aged 18-81 years [56.0(46.5, 64.5)years]. Based on whether delayed pleural effusion developed after injury, the patients were divided into delayed pleural effusion group ( n=66) and non-delayed pleural effusion group ( n=79). The clinical data of the patients in both groups were collected, including gender, age, underlying disease (diabetes mellitus and hypertension), cause of injury (traffic injury, blow injury, fall from height, and others), comorbid injuries (traumatic brain injury, maxillofacial fracture, clavicular fracture, scapular fracture, sternal fracture, spinal fracture, multiple rib fracture, pneumothorax, lung contusion, and pelvic fracture), severity of injury [injury severity score (ISS) and abbreviated injury scale (AIS) score for the chest], location and number of rib fractures, vital signs at admission (body temperature, heart rate, respiration, systolic blood pressure, diastolic blood pressure), and clinical test indices [white blood cells (WBC), hemoglobin (Hb), platelets (PLT), total protein (TP), albumin (ALB), C-reactive protein (CRP), procalcitonin (PCT), fibrinogen (FIB), fibrin degradation product (FDP), D-dimer (D-D), aspartate transaminase (AST), alanine transferase (ALT), and creatinine (Cr)]. Univariate analysis was conducted to assess the correlation between the forementioned factors and the development of delayed pleural effusion after multiple traumas. Multivariate Logistic regression analysis was used to determine the independent risk factors for the development of delayed pleural effusion after multiple traumas. Results:The results of univariate analysis showed that multiple rib fracture, pneumothorax, pulmonary contusion, chest AIS score, posterior rib fracture, number of rib fractures, TP, ALB, CRP, PCT and FDP were correlated with delayed pleural effusion in multiple trauma patients ( P<0.05 or 0.01); whereas gender, age, underlying disease, cause of injury, sternal fracture, spinal fracture, clavicular fracture, scapular fracture, pelvic fracture, maxillofacial fracture, traumatic brain injury, anterior rib fracture, ISS, vital signs at admission, WBC, Hb, PLT, FIB, D-D, AST, ALT, and Cr were not correlated with delayed pleural effusion in multiple trauma patients ( P>0.05). The results of multivariate Logistic regression analysis revealed that lung contusion ( OR=3.96, 95% CI 1.59, 9.85, P<0.01), ALB ( OR=0.79, 95% CI 0.66, 0.94, P<0.01), and CRP ( OR=1.02, 95% CI 1.01, 1.03, P<0.01) were significantly correlated with delayed pleural effusion in multiple trauma patients. Conclusion:Lung contusion, ALB, and CRP are the independent risk factors for delayed pleural effusion in multiple trauma patients.

Objective To evaluate the effect of standardized lipid-lowering therapy in acute stroke patients via high-resolution magnetic resonance vessel wall imaging(HRMR-VWI)to follow-up the characteristics changes of intracranial atherosclerotic plaques.Methods Twenty-two acute stroke patients(65 plaques)were enrolled,and their clinical and imaging data were collected on admission and after standardized lipid-lowering therapy(355-370 days).Diffusion weighted imaging(DWI),three-dimensional time of flight magnetic resonance angiography(3D-TOF-MRA),and HRMR-VWI were performed in all patients.According to the changes in non-high density lipoprotein(non-HDL),all patients were divided into the effective lipid-lowering group and the ineffective lipid-lowering group.The demographic information,plaques characteristics and the effect of standardized lipid-lowering therapy of all patients were compared.Results One(2.33％)plaque in the effective group showed reverse remodeling and four(18.18％)new plaques in the anterior circulation in the ineffective group.Patients in the effective group were significantly better than those in the ineffective group in terms of plaque thickness,load,remodeling index(RI),and the rate of increase in plaque thickness,load,stenosis,and RI,with statistically significant difference(P＜0.05).There was no statistical significance in the rate of stenosis between the two groups.Conclusion Standardized lipid-lowering therapy has differences in the prognosis of acute stroke patients,and HRMR-VWI may be conducive to individualized assessment of the lipid-lowering effect.

OBJECTIVE To analyze the clinical characteristics of nephrotic syndrome induced by sunitinib， and to provide reference for clinical rational drug use. METHODS Retrieved from CNKI， VIP， Wanfang data， PubMed， Web of Science and Medline， case report about sunitinib-induced nephrotic syndrome were collected from the inception to Oct. 30th， 2022. Those case reports were analyzed statistically in terms of gender， age， primary disease， drug use， clinical manifestations， treatment and outcome. RESULTS A total of 15 pieces of literature were collected and 17 patients were involved， including 10 males and 7 females. The average age of patients was （59.35±15.72） years. Among 17 patients， there were 10 patients with renal cell carcinoma and 7 patients with gastrointestinal stromal tumor， all of whom received evidence-based medication； the dosage of sunitinib in 15 cases was recorded， and all of them were within the recommended range of the instructions； 9 patients received combined therapy； the time from sunitinib application to the occurrence of nephrotic syndrome was 21 days-52 months， of which 11 cases were ≤2 years. The clinical manifestations in 13 patients were described， including edema， oliguria， foamy urine， weight gain， fatigue， dyspnea on exertion， etc. Eight patients had other adverse reactions induced by sunitinib before suffering from nephrotic syndrome， including new hypertension or worsening of original hypertension， and hand-foot syndrome. Renal biopsy mainly manifested as thrombotic microangiopathy， focal segmental glomerular sclerosis and immune complex glomerulonephritis. Sunitinib withdrawal or dosage reduction was adopted in all patients， and they were given symptomatic treatment such as glucocorticoids and antihypertensive agents. Symptoms of 16 patients were improved， and renal function of one patient deteriorated and hemodialysis was started. Sunitinib was re-challenged in 6 patients， elevated creatinine and substantial proteinuria recurred in 5 patients. CONCLUSIONS In clinical use of sunitinib， it is advisable to periodically monitor renal function. In case of deterioration of renal function， albuminuria， edema， etc.， relevant examinations should be implemented in time， and symptomatic intervention should be taken as soon as possible. Besides， we should be alert to the recurrence of nephrotic syndrome after sunitinib rechallenge.

Radiotherapy is an important treatment for malignant tumors. However, it is also one cause of damage to local normal tissues, such as radiation nephropathy, which is frequently induced during the radiotherapy of abdominal and pelvic tumors. The exact pathogenesis of radiation nephropathy is still unclear and is believed to be related mainly to factors including oxidative stress, cell aging, and gene changes presently. Moreover, there is a lack of effective treatments for radiation nephropathy. With an increase in the survival of tumor patients, radiation nephropathy has received increasing attention. This article mainly reviewed the research progress of radiation nephropathy from the aspects of pathogenesis and treatments, aiming to provide a reference for the research and clinical diagnosis and treatment of radiation nephropathy.

Objective:To investigate the changes of quadriceps femoris thickness with the length of stay in intensive care unit (ICU) in patients with sepsis, and to evaluate the diagnostic value of muscle changes in mortality.Methods:A prospective study was conducted, and 92 patients with sepsis who were admitted to the ICU of the Affiliated Hospital of Jining Medical College from January 2020 to December 2021 were enrolled. The thickness of quadriceps femoris [including the quadriceps femoris muscle thickness at the midpoint of the anterior superior iliac spine and the upper edge of the patella (M-QMLT), and at the middle and lower 1/3 of the patella (T-QMLT)] measured by ultrasound 1 day (D1), 3 days (D3), and 7 days (D7) after admission to the ICU were collected. The atrophy rate of quadriceps femoris was calculated 3 and 7 days after admission to the ICU compared with 1 day [(D3-D1)/D1 and (D7-D1)/D1, (TD3-TD1)/TD1 and (TD7-TD1)/TD1, respectively]. The demographic information, underlying diseases, vital signs when admission to the ICU and in-hospital mortality of all patients were recorded, and the differences of the above indicators between the two groupswere compared. Multivariate Logistic regression was used to analyze the influence of quadriceps femoris muscle thickness and atrophy rate on in-hospital mortality of septic patients. The receiver operator characteristic curve (ROC curve) was drawn to analyze the predictive value of quadriceps femoris muscle thickness and atrophy rate on in-hospital mortality of septic patients.Results:A total of 92 patients with severe sepsis were included, of which 41 patients died in hospital, 51 patients discharged. The in-hospital mortality was 44.6%. The muscle thickness of quadriceps femoris in severe septic patients decreased with the prolongation of ICU stay, and there was no significant difference between the two groups at the first and third day of ICU admission. The muscle thickness of quadriceps femoris at different measuring positions in the survival group was significantly greater than those in the death group 7 days after admission to the ICU [M-QMLT D7 (cm): 0.50±0.26 vs. 0.39±0.19, T-QMLT D7 (cm): 0.58±0.29 vs. 0.45±0.21, both P < 0.05]. The atrophy rate of quadriceps femoris muscle thickness at different measuring positions 3 and 7 days after admission to ICU in the survival group was significantly lower than those in the death group [(D3-D1)/D1: (8.33±3.44)% vs. (9.74±3.91)%, (D7-D1)/D1: (12.21±4.76)% vs. (19.80±6.15)%, (TD3-TD1)/TD1: (7.83±4.26)% vs. (10.51±4.75)%, (TD7-TD1)/TD1: (11.10±5.46)% vs. (20.22±6.05)%, all P < 0.05]. Multivariate Logistic regression analysis showed that M-QMLT D7, T-QMLT D7, (D3-D1)/D1, (D7-D1)/D1, (TD3-TD1)/TD1, (TD7-TD1)/TD1 were independent risk factors for in-hospital mortality (all P < 0.05). The results were stable after adjusting for confounding factors. ROC curve analysis showed that (TD7-TD1)/TD1 [area under the ROC curve (AUC) was 0.853, 95% confidence interval (95% CI) was 0.773-0.934] was superior to (D7-D1)/D1, T-QMLT D7, M-QMLT D7, (TD3-TD1)/TD1 and (D3-D1)/D1 [AUC was 0.821 (0.725-0.917), 0.692 (0.582-0.802), 0.683 (0.573-0.794), 0.680 (0.569-0.791), 0.622 (0.502-0.742)]. Conclusions:For septic patients in ICU, bedside ultrasound monitoring of quadriceps femoris muscle thickness and atrophy rate has a certain predictive value for in-hospital mortality, and a certain guiding significance in clinical treatment and predicting the prognosis of sepsis.

Objective: To investigate the application of single-molecule PCR (SM-PCR) in the detection of plasma ctDNA for the treat-ment of patients with advanced lung adenocarcinoma. Methods: In total, 30 patients diagnosed with advanced lung adenocarcinoma were enrolled between June 2017 and May 2018. ctDNA fragments of the target genes (EGFR, KRAS, BRAF, ALK, HER2, and TP53) from the blood samples were enriched by SM-PCR, and DNA libraries were prepared. Finally, a high-throughput sequencing was performed. The EGFR detection of tumor tissue samples was performed using real-time fluorescence PCR based on the amplification refractory mutation system (ARMS) and consistency in the results of EGFR mutation detection in the plasma and tissue was compared. Results:The results of both the methods were consistent (Kappa=0.867, P<0.001). The McNemar's test also indicated that the results are not statistically different (P=0.500). Conclusions: SM-PCR can be used for the detection of plasma EGFR mutations. The target detection sites are more comprehensive and multiple mutations can be detected at the same time. Results of the analysis are more precise and can be absolutely quantified.

Objective: To make a postural transfer belt for patients with cervical spinal cord injury, to reduce and prevent the corresponding nursing problems with traditional methods of transfer Methods: 44 patients with cervical spinal cord injury admitted to the ward from January to June 2017 were selected as the control group by traditional methods of postural metastasis, and 48 patients with cervical spinal cord injury admitted to the ward from July to December 2017 were selected as the observation group by using self-made transfer belt. Results: Number of the skin injury caused by transfer in observation group was 0 cases, in control group was four cases, and there was significant difference (χ²=1.91, P=0.049). Falls occur due to metastasis: there were 0 cases in the observation group and five cases in the control group, there was significant difference (χ²=2.39, P=0.026). The number of caregivers in the observation group decreased on average (1.21±0.08), and the number of caregivers in the control group decreased on average (0.86±0.09). The differences between the two groups are statistically significant (t=2.905, P=0.005). The results of the investigation on the escorts in the observation group showed that 46 (95.8%) people believed that the transfer belt was convenient for patients. 47 people believed that the transfer belt was safer and more labor-saving to use, accounting for 97.9%, and 47 people believed that the transfer belt would continue to be used when they went home, who occupied 97.9%. Conclusion The self-made transfer belt is convenient for the caregivers to carry the patients with cervical spinal cord injury, which effectively prevents the occurrence of skin injury, falls and other nursing problems, and improves the quality and experience of the caregivers. This technology is worthwhile to spread.

Objective To explore the value of echocardiography in evaluation of pulmonary venous in total anomalous pulmonary venous connection (TAPVC).Methods Fifty-five children with TAPVC were enrolled in the study.The data of echocardiography and CT angiography were retrospectively analyzed and compared with intraoperative findings.Results Totally 55 patients with TAPVC were classified into supra-cardiac type (n=24),cardiac type (n=20),infra-cardiac type (n=7) and mixed type (n=4) according to the sites of drainage of pulmonary venous in echocardiography.In 15 patients with obstruction of pulmonary vertical vein,the sites of obstruction in the supra-cardiac type mostly presented between vertical vein and superior vena cava or innominate vein,and the sites of obstruction in the infra-cardiac presented all between vertical vein and hepatic or portal vein.In 4 patients with pulmonary vein stenosis,3 cases with local pulmonary vein stenosis were all cardiac type,which presented between individual pulmonary vein and common confluence or right atrium;1 patient with diffuse pulmonary vein stenosis was infra-cardiac type.In 9 patients of abnormal individual pulmonary vein,8 cases were not detected by echocardiography,but all were detected by CT angiography.Conclusion Echocardiography is able to make more comprehensive evaluation for the pulmonary venous drainage,obstruction,and proximal stenosis of individual pulmonary vein in TAPVC.CT angiography is superior in evaluation of abnormalities of connection and amount of individual pulmonary vein,and imaging of distal pulmonary vein.

OBJECTIVEUsing simultaneous multi-gene mutation screening to investigate the new method molecular epidemiological basis of 225 patients with nonsyndromic hearing loss in Tianjin, and verifying the for simultaneous multi-gene mutation screening.

METHODSTwo hundred and twenty-five patients with severe non-syndromic deafness from Tianjin CDPF and Association of the Deaf were included in the study. The single nucleotide polymorphisms scan, (SNPscan) technique was used for screening the 115 spots mutations in three common deafness-related genes (GJB2, SLC26A4, mtDNA 12S rRNA) of patients with nonsyndromic hearing loss in Tianjin. We verified the results by Sanger sequencing.

RESULTSAmong the 225 patients, there were 111 cases of deafness caused by mutation (49.3%). Using this method, up to 50% of the patients in our study were identified to have hereditary HL caused by mutations in the three genes. 56 patients with the GJB2 mutations were detected (24.9%), including 30 cases of homozygous mutations (13.3%), 26 patients (11.6%) of compound heterozygous mutations, and 21 cases (9.33%) of single heterozygous mutations. 50 patients with the SLC26A4 mutations were detected (22.2%), including 22 cases of homozygous mutations(9.8%), 28 patients (12.4%) of compound heterozygous mutations, and 22 cases (9.8%) of single heterozygous mutations. mtDNA 12S rRNA A1555G mutation was detected in 5 patients (2.2%). mtDNA 12S rRNA 1494C>T mutation was not detected. We verified the results by Sanger sequencing. The accuracy of the sequencing results was 100%. The SNPscan cost eight hours and 160 yuan (each sample).

CONCLUSIONSApplying SNPscan technology can be accurate, rapid and cost-effective diagnostic screening in patients with hearing loss for etiology investigation. It is expected to become an effective means of large-scale genetic testing for hereditary deafness.
