Sepsis is a syndrome of systemic inflammatory response in which the body′s response to infection is dysregulated, and is characterized by persistent infection, excessive inflammation and immunosuppression, etc. It often leads to organ dysfunction and can be life threatening, and also a common complication after trauma. The pathogenesis of post-traumatic sepsis is still unclear at present due to the complexity of its etiology, progression and prognosis. Multi-omics technology is a method to combine two or more single omics for comprehensive analysis, which can reveal the interaction network among the disease-associated molecules from multiple perspectives and aspects and is of great significance for the analysis of the pathogenesis of post-traumatic sepsis. To this end, the authors reviewed the research progress on the role of multi-omics technology in elucidating the pathogenesis of post-traumatic sepsis from the perspectives of genomics, transcriptomics, proteomics, metabolomics, single-cell transcriptomics and combination of multi-omics technologies, etc so as to provide a reference for the researches on post-traumatic sepsis.

Objective To analyze the very high frequency(VHF)ultrasound features of mixed tumor of the skin(MTS),and to explore the diagnostic value of VHF ultrasound features for MTS.Methods A total of 63 cases of MTS confirmed by surgery and pathology in the Department of Dermatology of Hangzhou Third People's Hospital from January 2019 to March 2024 were selected as observation group,and 63 other benign skin tumors in the same period were used as control group.The VHF ultrasound features of MTS were retrospectively analyzed and summarized,and the diagnostic efficiency of VHF ultrasound features for MTS was evaluated.Results Compared with other benign skin tumors,there were no significant differences in the length diameter,transverse diameter,aspect ratio,presence or absence of calcification,cystic disease,blood flow grade and resistance index between two groups(P＞0.05).However,MTS had a more obvious pseudo-capsule,and most of the internal echoes were not uniform,and the posterior side was accompanied by a enhancing effect,and the blood flow was dominated by marginal blood flow,and the difference between two groups was obvious(P＜0.05).The receiver operating characteristic curve showed that the combination of pseudo capsule,internal echo,marginal flow and peripheral enhancement had the highest diagnostic efficacy,with an area under the curve of 0.772,a sensitivity of 77.8％ ,and a specificity of 71.4％ .Conclusion MTS have specific VHF ultrasound features,which can provide more assistance in the clinical diagnosis of MTS.

ObjectiveTo explore the mechanism of Chaihu Guizhitang （CHGZT） in alleviating neuropathic abdominal pain induced by 2，4，6-trinitrobenzene sulfonic acid （TNBS） in rats with chronic pancreatitis （CP）. MethodFifty male SD rats were randomly assigned into five groups： sham operation， CP model， and low-， medium-， and high-dose （4， 8， and 16 g·kg^-1， respectively） CHGZT groups. In the sham operation group， the abdomen was closed after the pancreas was gently stirred. The rat model of CP was established by retrograde injection of 2% TNBS-10% ethanol into the pancreatic duct. The oral administration of CHGZT started 4 weeks after modeling and lasted for 2 weeks. Pain threshold was measured by Von Frey fibers 6 weeks after surgery. Hematoxylin-eosin （HE） staining was employed to reveal the chronic inflammation and fibrosis of the pancreatic tissue. Immunohistochemmistry （IHC） was employed to detect the expression of PGP9.5 （a marker of pancreatic nerves） and reveal the inflammatory changes around the nerves. IHC and immunofluorescence （IF） were used to determine the location of ionized calcium-binding adaptor molecule-1 （Iba-1， microglia marker） and purinergic receptor P2X7 （P2RX7） and the co-expression of P2RX7 and Iba-1 in the thoracic spinal dorsal horn. ResultCompared with the sham operation group， the modeling increased the scores of pancreatic gland atrophy， inflammatory infiltration， and fibrosis （P<0.01）， the abdominal pain response under different force values （P<0.05， P<0.01）， and the score of peripancreatic inflammation. Moreover， the modeling up-regulated the expression of Iba-1 and P2RX7 in the thoracic spinal dorsal horn （P<0.01）. Compared with the model group， the high- and medium-dose CHGZT lowered the scores of pancreatic gland atrophy， inflammatory infiltration， and fibrosis， the abdominal pain response， and the score of peripancreatic inflammation （P<0.05， P<0.01）. The high-， medium-， and low-dose CHGZT all down-regulated the expression of Iba-1 and P2RX7 （P<0.01）. ConclusionCHGZT can significantly relieve abdominal pain in CP rat by suppressing the inflammation around nerves in the pancreas and the P2RX7 activation of microglia in the spinal dorsal horn.

Objective To investigate the prenatal imaging features of fetal congenital esophageal atresia and to further evaluate the value of MRI and ultrasound scan in the same condition.Methods This study recruited 12 singleton gravidas whose fetuses were initially suspected with congenital esophageal atresia by prenatal ultrasound scan and then confirmed by surgery and/or upper gastrointestinal angiography after birth at Guangzhou Women and Children's Medical Center from May 2011 to May 2017.Imaging features of prenatal MRI and ultrasonography of the 12 fetuses were retrospectively analyzed.Differences in imaging findings of these two methods were analyzed by Chi-square test.Results All 12 women received prenatal ultrasound examination and eight of them underwent MRI scan when fetal congenital esophageal atresia was suggested by ultrasound.Both ultrasound and MRI were capable of identifing polyhydramnios and absent or small stomach bubble (12/12 and 8/8,respectively).However,MRI was superior to ultrasound in detecting "pouch sign "/"oral filling sign" or poor filling of small intestine (7/8 vs 3/12 and 8/8 vs 0/12,x2 were 7.500 and 20.000,both P＜0.01).While,no statistical difference was shown in detecting curved tracheal between MRI and ultrasound (2/8 vs 0/12,x2=3.333,P=0.067).For Gross Ⅰ or Gross Ⅲ congenital esophageal atresia fetuses,no statistically significant difference was found in their imaging features (all P＞0.05).The total detection rates after 32 weeks of gestation of Gross Ⅰ and Gross Ⅲ cases were both 3/6.Conclusions Prenatal MRI is a vital supplement to ultrasound due to its high display rate of characterized features of congenital esophageal atresia.Thus,the combined use of ultrasound and MRI is of great importance for prenatal diagnosis of this fetal abnormality.

Objective To explore the clinical value of combined detection of serum beta human chorionic gonadotropin (β-hCG),estradiol (E2),progesterone (P) and antiphospholipid antibodies (ACA) in predicting the outcomes of early threatened abortion.Methods 80 pregnant women were chosen from six to eight weeks singleton pregnancies,50 cases of threatened abortion and 30 cases of normal pregnancy.The serum levels of β-HCG,estradiol,progesterone and ACA-IgG,ACA-IgM and ACA-IgA were detected.The threatened abortion patients were given intramuscular progesterone 20 mg/day/time for 1 week,then,the pregnancy outcomes were analyzed and the serum levels of β-HCG,estradiol and progesterone were explored.Results The serum β-HCG,estradiol and progesterone of the threatened abortion group [(5 140.77 ± 2 365.47) IU/L,(680.28 ± 306.06) pg/mL,(15.59 ± 3.65) pg/L]were lower than those of the normal pregnant women [(14 520.4 ± 11 016.24) IU/L,(1 142.81 ± 670.57) pg/mL,(27.6 ± 4.78) pg/L] (t =3.224,P =0.003 ; t =2.43,P =0.022 ; t =7.72,P =0.001).According to pregnancy outcome,patients with threatened miscarriages were divided into the two groups,including 45 patients with continuing pregnancies and 5 patients with inevitable miscarriages.The serum levels of β-HCG,estradiol and progesterone in ongoing pregnancies group [(10 829.42 ± 6 926.28) IU/L,(832.9 ± 397.91) pg/mL,(25.62 ± 4.51) pg/L] were higher than those in inevitable miscarriages [(6 310.14 ± 2 593.19) IU/L,(487.14 ± 275.47) pg/mL,(13.6 ±4.84) pg/L] (P ＜ 0.05) ;The serum levels of ACA-IgG,ACA-IgM and ACA-IgA in 80 cases tested,only 2 cases who appeared in the threatened abortion group were detected with the positive of serum ACA-IgG,accounted for 4％ (2/50) (x2 =68.05,P =0.000),occurred spontaneous abortion in the end.Conclusion Combined detection of serum ACA,β-HCG,estradiol and progesterone may be helpful for prognosis of threatened abortion.However,the clinical predictive value of ACA needs further study in the early threatened abortion.

BACKGROUND: Though there were many experiments addressing repairing osteochondral defects before, faulty restoration occurred at coupling interfaces. OBJECTIVE: To investigate the feasibility of repairing of osteochondral composite defects in rabbit knees with animal-origin osteochondral scaffold combined with bone marrow mesenchymal stem cells (BMSCs)/chondrocytes.METHODS: New Zealand white rabbits were randomly divided into the experimental, control and blank groups and prepared for unilateral knee joint osteochondral defects. Animal-origin osteochondral scaffold combined with BMSCs/chondrocytes, animal-origin osteochondral scaffold and no material was implanted to repair the defects in the experimental, control and blank groups, respectively. Healing condition was evaluated by gross observation, hematoxylin-eosin staining, and toluidine blue staining at 4, 8, and 12 weeks after operation. RESULTS AND CONCLUSION: At 12 weeks after operation, gross observation showed the defects were repaired completely without local depression and the regenerated tissues were fused with surrounding tissues in the experimental group. Hematoxylin-eosin staining and toluidine blue staining revealed that there were many new hyaline cartilages in the cartilage defects in which columnar cells were lined well and cartilage lacuna was obviously, also, there were many bony tissues in the bone defects. The regeneration cartilage, the underlying subchondral bone and host bone were coupled completely. The toluidine blue positive rate and histologic scores of the experimental group were superior to those of the control and blank groups (P < 0.05). It is demonstrated that animal-origin osteochondral scaffold combined with BMSCs/chondrocytes is an ideal method to repair defects between cartilage and the underlying subchondral bone.

BACKGROUND: The development of cartilage tissue engineering provides novel ideas for treatment of articular cartilage defects and implements construction of tissue-engineered cartilage in vivo.OBJECTIVE: To investigate the feasibility of constructing tissue-engineered osteochondral composite through bone marrow stem cells(BMSCs) cultured on the poly(lactide-co-glycolic acid) (PLGA), which was modified with collagen and cellular growth factors.METHODS: PLGA was made by phase separation technique, composited with collagen Ⅱ, basic fibroblast growth factor, and transforming growth factor-β1. The BMSCs of passage 3 were cultured on the above scaffolds. Thirty-six SD rats were randomly divided into experimental, control, and blank groups. These three groups received implantation of BMSCs composited with growth factors and collagen-PLGA, implantation of BMSCs composited with collagen-PLGA, and implantation of collagen-PLGA into the muscle, respectively. At 4, 8, and 12 weeks after surgery, cell directional differentiation and growth were examined by gross observation, hematoxylin-eosin staining, toluidine blue staining, collagen Ⅱ staining, and scanning electron microscope.RESULTS AND CONCLUSION: Gross observation showed that there were many chondroid tissues in the experimental group and fibrous tissues in the control and black groups. Stainings and electron microscope revealed that many chondroblasts and a few osteoclasts appeared in the composite of the experimental group. Toluidine blue and collagen Ⅱ stainings were positive in the experimental group and negative in the control and blank groups. These findings demonstrate that PLGA modified with collagen had a good cellular compatibility. BMSCs cultured on PLGA, which was modified with collagen and cellular growth factors, can construct the tissue-angineered osteochondral composite in rats.

Results Every indexes of the experi-mental group were better than those of the control group. Conclusions The whole-process nursing interven-tion mode can promote the comfort degree of patients undergoing radial artery puncture.

Objective To investigate the clinical significance of three-dim en sional CT in diagnosis and treatment of posterior pelvic ring fractures. Methods A retrospective analysis was done for 19 cases of posterior pelvic ring fractur es who were treated from March 2002 to August 2003 and had plain and three-dime nsional CT films. Their radiological characteristics and results were compared b etween the 2 kinds of film. Results 3-D CT corrected the misdiagnosis or uncert ainty of 9 cases who had plain radio-graphs. The 3-D CT showed obvious advanta ges over plain radio-graphs in detecting sacroiliac diastasis, sacroiliac joint fragments, fractures involving iliac and sacral lips abutting the sacroiliac jo int, sacral fracture and complicated comminuted fracture, because it clearly del ineated fractures of posterior pelvic ring and manifested the severity of commin ution and separation. Conclusion The 3-D CT scan provides valuable information for precise diagnosis and treatment plan for the complex posterior pelvic ring f ractures.
