Objective To investigate the effect of the spleen on the function of intestinal barrier during the course of acute pancreatitis in rats.Methods Rats were randomly divided into four groups: sham operation group; actue pancreatitis group; splenectomy group;splenectomy plus acute pancreatitis group.The serum levels of TNF-?,IL-1,IL-6 and IL-10 in each group were examined 24 hours after operation.Two days after operation ,the rate of bacterial translocation(BT) was determined and the terminal ileum was excised and examined by transmission electron microscopy to detect the injury of intestinal mucosa.Results The serum levels of TNF-?,IL-1?,IL-6 and IL-10 in splenectomy plus acute pancreatitis group were 3.06?3.61,16.46?5.52,19.90?6.89,6.94?3.93,and in acute pancreatitis group were 19.93?2.38, 42.79?4.31, 20.19?3.35, 39.28?12.69 respectively. The values of TNF-?, IL-1? and IL-10 were significantly lower in splenectomy plus acute pancreatitis group than those in acute pancreatitis group(P

The aim of this study is to establish stable transfected cell lines which could produce SPAG4L protein labeled with Myc and His tags in vitro. The open reading frame (ORF) of human SPAG4L was amplified by PCR and the fragments were cloned into eukaryotic expression vector pcDNA3.1/myc-His(-)A. The recombined plasmids of pcDNA3.1/myc-His(-)A/SPAG4L were verified by sequencing and digestion with enzymes. Then, the recombined plasmids were introduced into HeLa cells and screened by G418. Western blotting was performed to detect the expression of SPAG4L and its tags in stable transfected cell lines. SPAG4L and its tags were expressed in the stable cell lines transfected with pcDNA3.1/myc-His(-)A/SPAG4L, but not in the control group. Further study showed that SPAG4L colocalized with the endoplasmic reticulum(ER) marker PDI by immunofluorescence. The stable transfected cell lines established in this study will provide a powerful tool for further studies such as co-immunoprecipitation and pull-down.

Objective To assess the value of S index and FIB-4 for diagnosis of liver fibrosis in patients with chronic hepatitis B (CHB) by comparing with traditional indexes APRI and Forns.Methods A total of 361 patients with confirmed CHB from the First Hospital of Nanjing Medical University and Huashan Hospital Affiliated to Fudan University during January 2006 and December 2011 were enrolled in the study.The clinical,laboratory and pathological data of patients were collected.Four noninvasive score systems APRI,Forns,S index and FIB-4 were computed.With liver biopsy as the gold standard,the area under the ROC curve (AUROC) was used to assess the value of above 4 score systems in diagnosis of liver fibrosis,and Z test was performed to evaluate the effectiveness of above systems.Results The areas under ROC curve (AUCs) of APRI,Forns,S index and FIB-4 for significant fibrosis (≥S2) were (0.737 ±0.027),(0.716 ± 0.028),(0.745 ± 0.026) and (0.781 ± 0.025),respectively.When the cut off value of FIB-4 was set at 1.62,the sensitivity,specificity,positive predictive value (PPV) and negative predictive value (NPV) for diagnosis of significant fibrosis were 59.3％,85.8％,89.4％ and 51.2％,respectively,which were better than Forn index (Z =3.28,P =0.001).While for S4 (cirrhosis) the AUCs of APRI,Foms,S index and FIB-4 were (0.687 ± 0.035),(0.792 ± 0.028),(0.863 ± 0.024) and (0.832 ± 0.025),respectively.When the cut off value of S index was set at 1.06,the sensitivity,specificity,PPV and NPV for diagnosis of cirrhosis were 77.9％,85.5％,59.4％ and 93.5％,respectively,which were better than APRI and Forns (Z =6.74 and 3.21,P ＜ 0.01).Conclusions APRI,Forns,S index and FIB-4 are simple and accurate methods for assessing liver fibrosis.FIB-4 and S index are better than APRI and Forns in diagnosis of significant fibrosis and cirrhosis,which may replace liver biopsy in certain extend.

Objective To improve the diagnosis of oligodendroglioma(OD)in cerebellar hemispheres and discuss MRI features. Methods Clinical and imaging data of 7 cases with OD in cerebellar hemispheres were analyzed retrospectively,which were confirmed by surgery and pathology.Results In 7 patients,4 patients were OD,and 3 patients were anaplastic oligodendroglioma(AOD).MRI showed hypointense on T1WI and vividly hyperintense or mixed hyperintense on T2WI.The time intensity curve(TIC)manifested rise slowly;DWI(b=1 000 s/mm2) showed homogeneously hypointense or iso-hypointense.The ratios of OD and AOD were 1.753±0.784,1.660±0.551 respectively;Magnetic resonance spectroscopy(MRS)of oligodendrogliomas revealed a increased choline(Cho)and reduced N-acetylaspartate(NAA)without lactate(Lac)peak.Conclusion MRI manifestation of OD in cerebellar hemispheres has certain characteristics:the boundary of lesion is unclear, irregular in shape,easy to cystic and necrotic,with or without peripheral edema of the tumor,delayed enhancement,higher in Cho peak,lower in NAA peak and lacking in Lac peak.

Objective To analyse the risk factors associated with spontaneous intestinal perforation (SIP) in extremely premature infants/extremely low birth weight infants. Method From January 2015 to December 2018, infants with gestational age (GA)<28 weeks or birth weight (BW)<1000 g admitted to our neonatal intensive care unit were enrolled to the retrospective nested case-control study.The clinical data of SIP infants (SIP group) and infants with the same GA but without SIP (control group) were randomly selected and compared. Multivariable Logistic regression was used to analyse the risk factors of SIP. Result A total of 409 extremely premature infants/extremely low birth weight infants were born during the study period. Among them, 25 SIP infants and 55 controls were enrolled. The incidence of SIP in infants with GA 22～25 weeks was 11.8％(16/136), which is higher than infants with GA 26～27 weeks (2.0％, 5/247) (χ2=16.057, P<0.001). The incidence of SIP in infants with BW 400～749 g was 13.0％(14/108), which is higher than infants with BW 750～999 g (3.4％, 8/236) (χ2=11.343, P=0.001). Multivariate Logistic regression analysis showed that twins (OR=4.153, 95％CI 1.392～12.384, P=0.011), umbilical veins catheterization (OR=15.942, 95％CI 1.026～247.789, P=0.048) and ibuprofen use within 3 days after birth (OR=15.387, 95％CI 1.519～155.883, P=0.021) were independent risk factors of SIP. Conclusion The smaller the GA and BW, the higher the incidence of SIP. Twins,umbilical veins catheterization and ibuprofen use early after birth may be independent risk factors of SIP.

Objective:To study the risk factors of hypotension after ligation of patent ductus arteriosus (PDA) in very/extremely low birth weight infants (VLBWI/ELBWI).Method:From March 2016 to January 2021, preterm infants with birth weight <1 500 g receiving bedside PDA ligation in the neonatal intensive care unit (NICU) of our hospital were enrolled in the study. According to the occurrence of hypotension within 72 hours after ligation, the infants were assigned into non-hypotension group and hypotension group. The general status and perioperative conditions of the two groups were analyzed. Multivariate Logistic regression was used to analyze the risk factors of hypotension.Result:A total of 44 cases were enrolled, including 33 in non-hypotension group and 11 in hypotension group. Univariate analysis showed that hypotension group had significantly more cases with body weight <1 100 g during surgery and receiving preoperative high frequency oscillatory ventilation (HFOV) than non-hypotension group ( P<0.05). Multivariate Logistic regression analysis showed that weight <1 100 g during surgery ( OR=12.045, 95% CI 1.351~107.394, P=0.026) and receiving preoperative HFOV ( OR=27.832, 95% CI 1.363~568.292, P=0.031)were independent risk factors of hypotension. Conclusion:Hypotension is one of the common complications of PDA ligation in VLBWI/ELBWI. The infant's body weight during ligation and receiving preoperative HFOV are independent risk factors of hypotension.

  Objective  To study the demographic and clinical characteristics, correlation of genotype and phenotype and treatment of Blau syndrome to facilitate early diagnosis and timely treatment of Blau syndrome.  Methods  Seventy-two patients with Blau syndrome from 11 centers from May 2006 to April 2022 were retrospectively analyzed, and their general information, clinical data, laboratory examination and treatment medication were collected.  Results  The distribution of patients with Blau syndrome was uniform in geographical north and south of China, and there was no obvious gender bias. The mean age of onset was (14.30±12.81) months, and the age of diagnosis was (55.18±36.22) months. 35% of patients with Blau syndrome happened before 1 year old, and all patients developed before 5 years old. 87.50% (63/72) had granulomatous arthritis, 65.28% (47/72) had rash, 36.11% (26/72) had ocular involvement, 27.78% (20/72) had fever, and 15.28% (11/72) had pulmonary involvement. Arthritic manifestations of Blau syndrome were most at risk, followed by rash, ocular involvement, and fever.The first 25 months of the disease, the risk of developing a rash was the greatest. The risk of developing arthritis was the greatest between 25 months and 84 months. The main mutations were p.R334Q and p.R334W, and patients with p.R334Q mutation had relatively high incidence of fever (35.71%[5/14] vs. 14.29%[1/7], P=0.43) and ocular involvement (42.86%[6/14]vs. 28.57%[2/7], P=0.51). There was a relatively high incidence of rash (85.71%[6/7] vs. 64.29%[9/14], P=0.59) in patients with the p.R334W mutation. Forty-five patients(62.50%)were treated with a combina-tion of glucocorticoid and methotrexate. Twenty-two patients were treated with tumor necrosis factor antagonist in addition to glucocorticoid and methotrexate.  Conclusions  The risk of different clinical manifestations of Blau syndrome from high to low was arthritis, followed by rash, ocular involvement and fever. The main treatment was glucocorticoid combined with methotrexate, to which biological agents could be added.
