Clinical characteristics of patients with colon complications after necrotizing pancreatitis: a retrospective cohort study / 中华外科杂志

Objective: To investigate the clinical characteristics of colon complications in patients with necrotizing pancreatitis(NP). Methods: The clinical data of 403 patients with NP admitted to the Department of General Surgery,Xuanwu Hospital, Capital Medical University from January 2014 to December 2021 were retrospectively analyzed. There were 273 males and 130 females,aged (49.4±15.4) years(range: 18 to 90 years). Among them,there were 199 cases of biliary pancreatitis,110 cases of hyperlipidemic pancreatitis,and 94 cases of pancreatitis caused by other causes. A multidisciplinary diagnosis and treatment model was used to diagnose and treat patients. Depending on whether the patients had colon complications,they were divided into colon complications group and noncolon complications group. Patients with colon complications were treated with anti-infection therapy,parental nutritional support,keeping the drainage tube unobstructed,and terminal ileostomy. The clinical results of the two groups were compared and analyzed using a 1∶1 propensity score match(PSM) method. The t test,χ2 test, or rank-sum test was used to analyze data between groups,respectively. Results: The incidence of colon complications was 13.2%(53/403),including 15 cases of colon obstruction,23 cases of colon fistula,and 21 cases of colon hemorrhage. After PSM,the baseline and clinical characteristics at admission of the two groups of patients were comparable (all P>0.05). In terms of clinical outcome,compared to patients with NP without colon complications,the number of patients with colon complications who received minimally invasive intervention(88.7%(47/53) vs. 69.8%(37/53),χ2=5.736,P=0.030),the number of minimally invasive interventions (M(IQR))(2(2) vs. 1(1), Z=4.638,P=0.034),the number of patients with multiple organ failure(45.3%(24/53) vs. 32.1%(17/53),χ2=4.826,P=0.041),and the number of extrapancreatic infections(79.2%(42/53) vs. 60.4%(32/53),χ2=4.476,P=0.034) increased significantly. The time required for enteral nutrition support(8(30)days vs. 2(10) days, Z=-3.048, P=0.002), parental nutritional support(32(37)days vs. 17(19)days, Z=-2.592, P=0.009),the length of stay in the ICU(24(51)days vs. 18(31)days, Z=-2.268, P=0.002),and the total length of stay (43(52)days vs. 30(40)days, Z=-2.589, P=0.013) were also significantly prolonged. However,mortality rates in the two groups were similar(37.7%(20/53) vs. 34.0%(18/53),χ2=0.164,P=0.840). Conclusions: Colonic complications in NP patients are not rare,which can lead to prolonged hospitalization and increased surgical intervention. Active surgical intervention can help improve the prognosis of these patients.

Application progress of Ilizarov technique in orthopedics / 中国基层医药

Ilizarov technique is designed based on the "tension-stress principle". Application of the Ilizarov technique can help form a stable mechanical structure through external fixation. It only creates small wounds, without peeling off the surrounding tissue and periosteum. It connects different types of fixation pins and bone or soft tissue to form a traction force, which continuously stimulates the regeneration of bone and tissue and improves the local blood supply and early functional rehabilitation exercises, forming a complete set of minimally invasive orthopedic treatment systems. Ilizarov technique has achieved good results in fracture healing, deformity correction, tissue repair, osteomyelitis, bone nonunion, bone defect, and bone tumor. This paper will summarize the clinical application and research of the Ilizarov technique in orthopedics and explore the key problems of the Ilizarov technique that need to be solved at present.

APPL2 Negatively Regulates Olfactory Functions by Switching Fate Commitments of Neural Stem Cells in Adult Olfactory Bulb via Interaction with Notch1 Signaling / 神经科学通报·英文版

Adult olfactory neurogenesis plays critical roles in maintaining olfactory functions. Newly-generated neurons in the subventricular zone migrate to the olfactory bulb (OB) and determine olfactory discrimination, but the mechanisms underlying the regulation of olfactory neurogenesis remain unclear. Our previous study indicated the potential of APPL2 (adaptor protein, phosphotyrosine interacting with PH domain and leucine zipper 2) as a modulating factor for neurogenesis in the adult olfactory system. In the present study, we report how APPL2 affects neurogenesis in the OB and thereby mediates olfactory discrimination by using both in vitro neural stem cells (NSCs) and an in vivo animal model-APPL2 transgenic (Tg) mice. In the in vitro study, we found that APPL2 overexpression resulted in NSCs switching from neuronal differentiation to gliogenesis while APPL2 knockdown promoted neurogenesis. In the in vivo study, APPL2 Tg mice had a higher population of glial cells and dampened neuronal production in the olfactory system, including the corpus callosum, OB, and rostral migratory stream. Adult APPL2 Tg mice displayed impaired performance in olfactory discrimination tests compared with wild-type mice. Furthermore, we found that an interaction of APPL2 with Notch1 contributed to the roles of APPL2 in modulating the neurogenic lineage-switching and olfactory behaviors. In conclusion, APPL2 controls olfactory discrimination by switching the fate choice of NSCs via interaction with Notch1 signaling.

Effect of enhancer of zeste homolog 2 on the expression of glial cell line-derived neurotrophic factor family receptor α-1 in the colon tissue of children with Hirschsprung's disease / 中国当代儿科杂志

OBJECTIVE@#To study the expression levels of glial cell line-derived neurotrophic factor family receptor α-1 (GFRα1) and enhancer of zeste homolog 2 (EZH2) in the intestinal tissue of children with Hirschsprung's disease (HSCR), as well as the role of EZH2 in the regulation of GFRα1 gene expression and the pathogenesis of HSCR.@*METHODS@#The samples of colon tissue with spasm from 24 children with HSCR after radical treatment of HSCR were selected as the experimental group, and the samples of necrotized colon tissue from 18 children with neonatal necrotizing enterocolitis after surgical resection were selected as the control group. Real-time PCR and Western blot were used to measure the expression levels of GFRα1 and EZH2 in colon tissue in both groups. Human neuroblastoma SH-SY5Y cells were divided into an EZH2 over-expression group and a negative control group. The cells in the EZH2 over-expression group were transfected with pCMV6-EZH2 plasmid, and those in the negative control group were transfected with pCMV6 plasmid. The expression levels of EZH2 and GFRα1 were measured after transfection.@*RESULTS@#Compared with the control group, the experimental group had significant reductions in the mRNA and protein expression levels of GFRα1 and EZH2 in colon tissue (P<0.05), and the protein expression of EZH2 was positively correlated with that of GFRα1 (r=0.606, P=0.002). Compared with the negative control group, the EZH2 over-expression group had significant increases in the expression levels of EZH2 and GFRα1 after SH-SY5Y cells were transfected with EZH2 over-expression plasmid (P<0.05).@*CONCLUSIONS@#Low expression of EZH2 in the colon tissue of children with HSCR may be one of the causes of inadequate expression of GFRα1 and onset of HSCR.

miR-125a-5p suppresses epithelial-mesenchymal transition via GSK-3β/Snail signaling pathway in breast cancer cells / 中国病理生理杂志

AIM:To investigate the function of microRNA-125a-5p (miR-125a-5p) on epithelial-mesenchy-mal transition ( EMT) of breast cancer cells via GSK-3β/Snail signaling pathway. METHODS:The expression of miR-125a-5p in normal breast epithelial cells and breast cancer cells, as well as the transfection efficiency of miR-125a-5p plas-mid in MDA-MB-231 cells was detected by RT-qPCR. The chemotaxis ability and invasion ability were detected by chemo-taxis assay and Transwell invasion assay. The changes of EMT-related markers, the protein level of phosphorylated glycogen synthase kinase-3β (p-GSK-3β) and the nuclear translocation of Snail were determined by Western blot. RESULTS:The expression of miR-125a-5p in the breast cancer cells was significantly lower than that in the normal breast epithelial cells. The expression of miR-125a-5p was significantly higher in MDA-MB-231/miR-125a-5p cells than that in MDA-MB-231/NC cells. The ability of epithelial growth factor (EGF) at 10 μg/L to induce chemotaxis of MDA-MB-231 cells was the stron-gest. Compared with MDA-MB-231/NC group, stimulation of EGF decreased the invasion ability of MDA-MB-231/miR-125a-5p cells, and resulted in the increase in E-cadherin expression, while significantly decreased the protein levels of vi-mentin and p-GSK-3β. Meanwhile, the nuclear localization of Snail was significantly inhibited. The invasion capacity of MDA-MB-231/miR-125a-5p+GAB2 cells was significantly enhanced compared with MDA-MB-231/miR-125a-5p +Con cells, the expression of E-cadherin was decreased, and the protein levels of vimentin and p-GSK-3β were significantly in-creased, while the nuclear localization of Snail was promoted. CONCLUSION:miR-125a-5p suppresses EMT via GSK-3β/Snail signaling pathway, thus inhibiting the invasion ability of breast cancer cells.

Objective To explore the demographic characteristics and pregnant outcomes of the reproductive women with HIV infection. Methods A retrospective study was conducted based on surveillance of provincial HIV positive pregnant women during 2010-2014. All HIV infected women were enrolled. We compared their characteristics and pregnant outcomes in different groups according to their delivery history. Results The overall HIV prevalence among pregnant women was 0.03% (843/3310646) in this study. Among them, the proportion of HIV reproductive women was 50.33%. 59 out of 91 (64.84%) areas were reported with reproductive HIV women. The number of areas for reproductive HIV women per 10000 pregnant women was 1.98-8.45 for 31 areas. The obvious differences were observed in the distribution of age, minority, education, marriage, birth place, gravidity, sex partner infection status, time of diagnose between the two groups. No significant differences were found in proportion of stillbirths, low birth weight or preterm birth between the two groups. Totally, 5 infants were identified with HIV infections, who were all delivered by reproductive women. Conclusion HIV reproductive women were with advanced age, low education and non-local residents and so on, and 5 infants were identified with HIV infections in this study.

<p><b>OBJECTIVE</b>To investigate the clinical characteristics and curative effect in 61 adult patients with acute lymphoblastic leukemia (ALL).</p><p><b>METHODS</b>The clinical data of 61 patients (≥15 years old) with ALL enrolled from January 2010 to December 2014 were studied retrospectively. The relationship between clinical characteristics and curative effect was analyzed. The univariate and multivariate analyses related with the overall survival (OS) and disease free survival (DFS) were conducted by using the method of COX regression analysis.</p><p><b>RESULTS</b>Forty-four patients obtained complete remission (CR) in all 61 cases. The total CR rate was 72.13%. Age of onset, WBC count at first visit, CNS involvement or not, status of myeloid antigen expression and Ph chromosome condition were the important factors affecting the CR rate (P<0.05). The 2 years OS rate of all the 61 cases was 28.13%, the median OS time was 11 months (95% CI 9.58-12.42). The 2 years OS rate and DFS rate of the 44 patients in CR were 39.57% and 34.29% respectively. As showed by univariate analysis, the age of onset, WBC count at first visit, whether achieved CR or not after induction chemotherapy, and whether accepted consolidation therapy or allo-HSCT therapy after CR were factors affecting the prognosis of adult ALL patients. The result of multivariate analysis showed that the older age (P=0.001), induction chemotherapy did not achieve CR (P=0.018) and patients did not received consolidation after CR(P=0.005) , all these were independent risk factors for DFS.</p><p><b>CONCLUSION</b>The CR rate after induction chemotherapy is high in adult ALL patients, but the OS rate is low. To achieve CR and to maintain consolidation treatment after CR may be helpful to improve the long-term survival.</p>

Effects of TCM Staged Sequential Therapy on Expressions of Matrix Metalloproteinase-9 and Its Inhibitor in Asthmatic Rats with Airway Remodeling / 世界科学技术-中医药现代化

This study was aimed to verify the effects of staged sequential therapy on expressions of matrix metalloproteinase-9 (MMP-9) and its inhibitor TIMP-1 within lung tissues in asthmatic rats with the airway remodeling, by applying a series of tests such as the immunohistochemistry, western blot and real-time fluorescent quantitative PCR. SD rats were randomly divided into 7 groups, which were the asthmatic group (Group X), the normal group (Group Z), the No. 1 sequential therapy group (Group A1), the No. 2 sequential therapy group (Group A2), the No. 3 sequential therapy group (Group A3), the montelukast group (Group M), and the budesonide group (Group B). The asthmatic model was established in each group except Group Z, by sensitization with both ovalbumin (OVA) and aluminium hydroxide via injection at the 1st, 8th and 15th day in a 22-day duration, followed by OVA aerosol inhalation every other day for 8 weeks for asthma activation. At the 8th day after the asthmatic model was established, Group A1 was orally given Ma-Xing Er-Chen Tang (MXECT) during acute phase while given normal saline (NS) during catabasis and stable phase; Group A2 was given MXECT during acute phase, and given modified Jin-Shui Liu-Jun Jian (JSLJJ) during catabasis as well as given NS during stable phase; Group A3 was given MXECT during acute phase, and given modified JSLJJ during catabasis as well as given Liu-Wei Di-Huang (LWDH) Powders during stable phase;Group M was given salbutamol via aerosol inhalation after stimulation, while orally given montelukast during catabasis and stable phase; Group B was given salbutamol via aerosol inhalation after stimulation, while given inhaled budesonide during catabasis and stable phase; Group X was given NS. After the 7-week intervention, the immunohistochemistry, western blot and real-time quantitative PCR were applied to analyze the location and quantitative expression of MMP-9 and TIMP-1, so as to find out the biological mechanism on expressions of MMP-9 and TIMP-1 in lung tissues of asthmatic rats from molecular levels to gene levels. The results of immunohistochemistry, western blot and real-time fluorescent quantitative PCR showed as follows. Compared with Group Z, the contents of MMP-9 and TIMP-1 increased significantly within lung tissues in Group X. Compared with Group X, the contents of MMP-9 and TIMP-1 decreased within lung tissues of asthmatic rats in each treatment group. It was concluded that the expression of MMP-9 and TIMP-1 elevated during asthma. TCM staged sequential therapy can regulate the ratio between MMP-9 and its inhibitor so as to block the airway remodeling, by decreasing the expression of MMP-9 and its inhibitor within lung tissues in asthmatic rats. This is one of the important action mechanisms.

Clinical application of BCR/ABL probes in myeloproliferative disorders / 中国实验血液学杂志

This study was purposed to explore the application value of fluorescence in situ hybridization (FISH) detection in differential diagnosis of chronic myeloproliferative disorders (CMPD) and Ph(+) acute lymphoblastic leukemia (Ph(+) ALL), as well as in dynamic monitoring of minimal residual disease (MRD) after treatment. The BCR/ABL fusion gene of newly diagnosed and treated cases was detected by using BCR/ABL (ES) probe and BCR/ABL (DF) probe respectively. The results showed that among 49 newly diagnosed cases considered as CMPD, 28 cases met the criterion of CML morphologically, out of them 23 cases were eventually diagnosed to be CML and with morphological consistent rate 82.1% (23/28), the sensitivity and specificity all were 100% (23/23). The BCR/ABL positive rate of eventually diagnosed cases was 81.3% ± 17.7%. Among 13 cases received allogeneic haemopoietic stem cell transplantation (allo-HSCT), 9 cases achieved long-term disease-free survival and 4 cases relapsed, the several monitoring for whom after donor lymphocyte infusion (DLI) and imatinib treatment or allo-HSCT showed BCR/ABL negative. Among 16 cases treated with imatinib, 11 cases remained BCR/ABL negative after 1 year; 5 cases showed BCR/ABL positive during 6, 7 and 10 years after treatment, respectively, but out of them BCR/ABL positive in 1 case turned negative after allo-HSCT. It is concluded that the FISH is sensitive and specific diagnostic technique, the detection of BCR/ABL fusion gene in newly diagnosed and treated cases by using 2 different probes can help to fast and accurately determine the differential diagnosis for CML and Ph(+) ALL, and dynamically monitor the MRD after treatment with imatinib and allo-HSCT.
