The clinical data of one child with metanephric stromal tumor (MST) and BRAF V600E gene mutation admitted to the First Affiliated Hospital of Zhengzhou University in June 2022 was analyzed retrospectively.Literature was reviewed.The patient, a 2-year-old girl, was diagnosed with a tumor in the left abdomen.The maximum diameter of the tumor was 10.5 cm.A radical nephrectomy was performed on the left kidney, and postoperative pathology revealed MST.Microscopically, the tumor had no envelope and exhibited expansive growth.The tumor cells were fusiform or stellate, and nuclear division was visible in the cell-rich region.Dysplastic blood vessels were seen inside the tumor.The tumor cells around the blood vessels and invaginated renal tubules were arranged like onion skin.CD34 was detected positive by immunohistochemical staining, and BRAF V600E mutation was also detected positive by fluorescent polymerase chain reaction.A total of 21 relevant case reports were retrieved, including 16 in English and 5 in Chinese.Fifty-eight MST patients, including the one in this report were analyzed.These patients were aged 2 days to 15 years, with a median age of 2 years.Except for 2 patients with unknown sex, the ratio of male to female was about 1.4∶1.0.Most MST patients were asymptomatic, with an average tumor size of 5.3 cm.The tumor cell CD34 showed positive expression in different degrees.Eight patients received the BRAF V600E mutation detection, and the results were all positive.Fifty-eight patients underwent nephrectomy and were followed up for 0-156 months, of which 7 patients were assisted with radiotherapy and chemotherapy.During the follow-up, 1 patient died, and 1 patient had a relapse.MST is a rare benign renal stromal tumor. BRAF V600E mutations are detected in a variety of malignancies.This paper is the first to report MST with BRAF V600E mutation in China and points out the importance of molecular detection of BRAF mutation for accurate diagnosis of MST.

OBJECTIVETo investigate the value of combined determination of neutrophil CD64 and procalcitonin (PCT) in the early diagnosis of neonatal bacterial infection.

METHODSAccording to discharge diagnosis, 37 neonates with bacterial infection were divided into sepsis (n=15) and ordinary infection (non-sepsis) groups (n=22). Twenty-one neonates without infection who were hospitalized during the same period of time were enrolled as the control group. Venous blood samples were collected immediately after admission. Flow cytometry was used to measure the serum level of neutrophil CD64. Chemiluminescence and immune transmission turbidimetry were used to measure the serum levels of PCT and CRP respectively.

RESULTSThe sepsis group had higher serum levels of neutrophil CD64, PCT, and CRP than the control group (P<0.01), the ordinary infection group had a higher serum level of neutrophil CD64 than the control group (P<0.01), and the sepsis group had higher serum levels of PCT and CRP than the ordinary infection group (P<0.01). The areas under the ROC curve (AUC) of neutrophil CD64, PCT, and CRP in diagnosing bacterial infection were 0.818, 0.818, and 0.704 respectively, and the AUC of combined neutrophil CD64 and PCT was 0.926. A combination of neutrophil CD64 and PCT had a sensitivity of 97.29% and an accuracy of 89.65% in the early diagnosis of neonatal bacterial infection.The sensitivity and accuracy were higher than those of a combination of CRP and neutrophil CD64 or PCT as well as neutrophil CD64, PCT, or CRP alone for the early diagnosis of neonatal bacterial infection.

CONCLUSIONSThe combined determination of neutrophil CD64 and PCT can improve the sensitivity and accuracy in the diagnosis of neonatal bacterial infection, which helps with early identification of bacterial infection.

OBJECTIVETo investigate the relationship between the clinical character and therapeutic strategy and prognosis in severe acute pancreatitis.

METHODSFrom January 2001 to December 2005, 783 patients with SAP were treated. Therapeutic strategy was selected based on the preliminary scheme for diagnosis and treatment of severe acute pancreatitis by pancreatic surgery society of CMA. All the patients were divided into biliary group and non-biliary group, while 375 patients in biliary group, with 182 patients treated operatively and 193 patients treated nonoperatively; and 408 patients in non-biliary group, with 147 patients treated operatively and 261 patients treated nonoperatively.

RESULTSThere were 698 survivals, the overall survival rate was 89.1%. 357 survivals in the biliary SAP group, the survival rate was 95.0%, in which 171 survivals from operation treated cases, with the survival rate of 94.0%, and 186 survivals from non-operation treated cases, with the survival rate of 96.4%; 341 survivals in the non-biliary SAP group, the survival rate was 84.0%, in which 110 survivals from operation treated cases, with the survival rate of 74.8%, and 231 survivals from non-operation treated cases, with the survival rate of 88.5%. 48.3% patients of the survival group had organ dysfunction, and 18.3% patients had multiple organ dysfunctions, while 100% patients of the death group had organ dysfunction, and 97.6% patients had multiple organ dysfunction. Respiratory dysfunction was found to be the most common cause totally followed by nerve system dysfunction and shock, with the rates of 26.3%, 11.7% and 10.3%, respectively. Respiratory dysfunction, renal dysfunction and cardiac dysfunction are most commonly in death group, with the rate of 94.1%, 60.0% and 60.0%, respectively. The rate of fungi infection in the survival group and death group were 8.9% and 37.6%. The rates of alimentary tract fistula in the survival and death group were 0.9% and 14.1%, respectively.

CONCLUSIONSThe therapy aiming at the cause for biliary SAP and the operation aiming at infected pancreatic necrosis is helpful to improve curative rate; MODS is the main cause of death in severe acute pancreatitis. Respiratory dysfunction, renal dysfunction and cardiac dysfunction are high risk factors.

Objective:To observe serum levels of high sensitive C reactive protein(hsCRP),interleukin(IL)-6, tumor necrosis factor(TNF)-α and hepatocyte growth factor(HGF)in patients with ischemic cerebrovascular dis-ease(ICVD),and analyze their correlation with blood lipids and anticardiolipin antibody(ACA)levels.Methods:A total of 45 ICVD patients treated in our hospital from Mar 2015 to Aug 2016 were regarded as ICVD group.An-other 45 non-ICVD patients treated in our hospital during the same period were regarded as non-ICVD control group.Serum levels of hsCRP,IL-6,TNF-α,HGF,blood lipids and ACA were observed and compared between two groups,and correlation among serum levels of hsCRP,IL-6,TNF-α and HGF,blood lipids and ACA levels were analyzed in ICVD patients.Results:Compared with non-ICVD control group,there were significant rise in se-rum levels of hsCRP[(4.69 ± 1.31)mg/L vs.(8.87 ± 1.56)mg/L],IL-6[(12.17 ± 4.33)mg/L vs.(34.26 ± 5.15)mg/L],TNF-α[(28.45 ± 2.18)pg/ml vs.(48.35 ± 3.15)pg/ml],HGF[(502.34 ± 15.36)pg/ml vs. (876.25 ± 18.15)pg/ml],ACA[(4.11 ± 0.65)IU/L vs.(7.89 ± 1.02)IU/L],total cholesterol[(4.68 ± 1.12) mmol/L vs.(5.57 ± 1.21)mmol/L],low density lipoprotein cholesterol[(2.62 ± 0.49)mmol/L vs.(3.24 ± 0.87) mmol/L]and triglyceride[(1.42 ± 0.31)mmol/L vs.(1.84 ± 0.37)mmol/L],and significant reduction in serum level of high density lipoprotein cholesterol[(1.28 ± 0.25)mmol/L vs.(1.02 ± 0.22)mmol/L]in ICVD group,P=0.001 all.Pearson correlation analysis indicated that serum levels of hsCRP,IL-6,TNF-α and HGF were signifi-cant positively correlated with serum levels of ACA,TC,LDL-C and TG(r=0.468~0.632,P<0.05 or <0.01), and significant inversely correlated with HDL-C level(r= -0.571~ -0.511,P<0.05 or < 0.01)in ICVD pa-tients.Conclusion:Serum levels of hsCRP,IL-6,TNF-α and HGF significantly rise in ICVD patients,and they are closely correlated with levels of blood lipids and ACA,which can serve as important indexes monitoring ICVD.

OBJECTIVETo investigate the effects of Vaspin on lipopolysaccharide (LPS)-induced acute respiratory distress syndrome (ARDS) in mice and explore the possible mechanism.

METHODSForty male C57B/L6 mice were randomized equally into control group, LPS group, Vaspin group and wortmannin group with corresponding treatments. The pathological changes of the lung tissues were evaluated by HE staining, and the severity of pulmonary edema was measured according to the wet/dry ratio (W/D) of the lung tissue. The lung permeability was evaluated by detecting total protein concentrations in the bronchoalveolar lavage fluid (BALF) using bicinchoninic acid (BCA) assay. Myeloperoxidase (MPO) activity in the lung tissue was detected using a MPO assay kit, and the levels of interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) in the lungs were measured using ELISA. Immunohistochemical staining was performed to detect the expression of vascular cell adhesion molecule-1 (VCAM-1) and Western blotting was used to detect the protein expressions of cleaved caspase-3 and p-Akt in the lung tissues.

RESULTSCompared with the control group, the mice in LPS group displayed typical ARDS pathological changes in the lungs with significantly increased W/D, total protein concentrations in BALF, lung MPO activity, levels of IL-1β and TNF-α, and pulmonary expressions of VCAM-1 and cleaved caspase-3 (P<0.05) but decreased expression of p-Akt (P<0.05). These changes induced by LPS were significantly alleviated by the administration of Vaspin (P<0.05). The protective effects of Vaspin against ARDS were obviously attenuated by the PI3K inhibitor wortmannin (P<0.05).

CONCLUSIONVaspin protects against LPS-induced ARDS in mice possibly by inhibiting inflammation and protecting vascular endothelium through upregulation of the PI3K/Akt signal pathway.

OBJECTIVETo investigate the findings of contrast-enhanced multislice computed tomography (MSCT) that characterize intraductal papillary neoplasms of bile ducts (IPNB).

METHODSThe MSCT findings and clinical data of 16 cases of IPNB proven by surgical pathology were reviewed retrospectively.

RESULTSAmong the 16 cases, nine were adenoma (multi-lesions, n = 5; single lesions, n = 4) and seven were adenocarcinoma (multi-lesions, n = 4; single lesions, n = 3). Among the nine adenoma cases, seven showed nodules or masses in the expanding intrahepatic bile ducts with asymmetrical low density on plain scan, and two showed obvious expansion of biliary ducts and the inner wall of bile ducts was rough. All seven of the adenocarcinoma cases showed nodules or masses in the expanding intrahepatic bile ducts with asymmetrical low density-like adenoma. When contrast enhancement was applied, the nine adenoma cases manifested slight-to-moderate degrees of asymmetrical enhancement. For the seven adenocarcinoma cases, two showed asymmetrical enhancement similar to that of the adenoma cases and five showed continued enhancement; one case showed malignant infiltration of the bile duct and evident damage in the adjacent hepatic tissue. The CT plain scan findings for the two groups (adenoma and adenocarcinoma) were not significantly different (t = -1.17, P = 0.2632). Significantly different findings were obtained with the MSCT imaging analysis for the arterial phase (t = 6.53, P less than 0.01) and the portal vein phase (t = 5.63, P less than 0.01). All cases showed asymmetrical expansion of intrahepatic biliary ducts, diffuse or local, and four cases showed moderate expansion of the common bile duct. One adenocarcinoma case showed intumescence in the celiac lymph node by moderate asymmetrical enhancement.

CONCLUSIONMSCT is helpful for the differential diagnosis of IPNB from other hepatic lesions.

Objective To summarize the clinical effects and experiences of rapid pore cranial drilling and ventricular drainage treatment on ventricular hemorrhage to evaluate the performance of rapid pore cranial drilling. Methods The clinical data of 3571 patients with ventricular hemorrhage performed the rapid pore cranial drilling and ventricular drainage treatment from 13 hospitals of Shandong province since 1977 were retrospectively analyzed and concluded; these data were compared with those in patients received traditional Dandy's device. Results In these 3571 patients, the cure rate was 27.1%, the improvement rate was 49.1%, and the death rate was 23.8%. Rapid pore drilling needed no scalp incision, no suction, no coagulation, or no special lighting, only needed puncturing the scalp, drilling through the cranium and dura matter, implanting drainage tube and stitching it up; one can manage it in about 5 minutes at bedside; while the traditional Dandy's drilling occupied 3 people in the operating room, needed more than 20 procedures, and plus the time transporting the patient, it needed at least 60 minutes or more to finfish the procedures. Rapid pore cranial drill device is superior to Dandy's cranial drill device in operating procedures, technical performance, operation conditions, personnel and time-consuming. Conclusion Rapid pore cranial drilling greatly simplifies the operating procedures, saves precious time for the seriously ill patients, reduces the mortality and improves the effectiveness of the treatment. After 35 years of clinical practice, to those patients seriously ill needed ventricular drainage treatment to rescue their lives, rapid pore cranial drilling is superior to traditional Dandy's drill technic, and is an effective method treating such diseases.

During coronavirus disease 2019 epidemic, the treatment of severe trauma has been impacted. The Consensus on emergency surgery and infection prevention and control for severe trauma patients with 2019 novel corona virus pneumonia was published online on February 12, 2020, providing a strong guidance for the emergency treatment of severe trauma and the self-protection of medical staffs in the early stage of the epidemic. With the Joint Prevention and Control Mechanism of the State Council renaming "novel coronavirus pneumonia" to "novel coronavirus infection" and the infection being managed with measures against class B infectious diseases since January 8, 2023, the consensus published in 2020 is no longer applicable to the emergency treatment of severe trauma in the new stage of epidemic prevention and control. In this context, led by the Chinese Traumatology Association, Chinese Trauma Surgeon Association, Trauma Medicine Branch of Chinese International Exchange and Promotive Association for Medical and Health Care, and Editorial Board of Chinese Journal of Traumatology, the Chinese expert consensus on emergency surgery for severe trauma and infection prevention during coronavirus disease 2019 epidemic ( version 2023) is formulated to ensure the effectiveness and safety in the treatment of severe trauma in the new stage. Based on the policy of the Joint Prevention and Control Mechanism of the State Council and by using evidence-based medical evidence as well as Delphi expert consultation and voting, 16 recommendations are put forward from the four aspects of the related definitions, infection prevention, preoperative assessment and preparation, emergency operation and postoperative management, hoping to provide a reference for severe trauma care in the new stage of the epidemic prevention and control.
