RESUMO
The COVID-19 epidemic has spread to the whole world for three years and has had a serious impact on human life, health and economic activities. China's epidemic prevention and control has gone through the following stages: emergency unconventional stage, emergency normalization stage, and the transitional stage from the emergency normalization to the "Category B infectious disease treated as Category B" normalization, and achieved a major and decisive victory. The designated hospitals for prevention and control of COVID-19 epidemic in Tianjin has successfully completed its tasks in all stages of epidemic prevention and control, and has accumulated valuable experience. This article summarizes the experience of constructing a hospital infection prevention and control system during the "Category B infectious disease treated as Category A" period in designated hospital. The experience is summarized as the "Cluster" hospital infection prevention and control system, namely "three rings" outside, middle and inside, "three districts" of green, orange and red, "three things" before, during and after the event, "two-day pre-purification" and "two-director system", and "one zone" management. In emergency situations, we adopt a simplified version of the cluster hospital infection prevention and control system. In emergency situations, a simplified version of the "Cluster" hospital infection prevention and control system can be adopted. This system has the following characteristics: firstly, the system emphasizes the characteristics of "cluster" and the overall management of key measures to avoid any shortcomings. The second, it emphasizes the transformation of infection control concepts to maximize the safety of medical services through infection control. The third, it emphasizes the optimization of the process. The prevention and control measures should be comprehensive and focused, while also preventing excessive use. The measures emphasize the use of the least resources to achieve the best infection control effect. The fourth, it emphasizes the quality control work of infection control, pays attention to the importance of the process, and advocates the concept of "system slimming, process fattening". Fifthly, it emphasizes that the future development depends on artificial intelligence, in order to improve the quality and efficiency of prevention and control to the greatest extent. Sixth, hospitals need to strengthen continuous training and retraining. We utilize diverse training methods, including artificial intelligence, to ensure that infection control policies and procedures are simple. We have established an evaluation and feedback mechanism to ensure that medical personnel are in an emergency state at all times.
RESUMO
Objective:To investigate the effects of long non-coding RNA Wilms tumor 1 associated protein pseudogene 1(WTAPP1)on the proliferation,invasion,migration and Wnt/β-catenin signaling pathway of nephroblastoma cells. Methods:Real-time fluorescence quantitative PCR was used to detect the relative expression level of WTAPP1 in 48 cases of nephroblastoma tumor tissues and their matched adjacent tissues,human nephroblastoma cells(SK-NEP-1)and normal renal epithelial cells(PCS-400-01 0,PCS-400-011 and PCS-400-01 2).The clinicopathological characteristics and prognosis of nephroblastoma patients with high or low WTAPP1 expression of were analyzed and compared.SK-NEP-1 cells were infected with lentivirus carrying the full-length WTAPP]gene(WTAPP1 overexpression)or shRNA targeting WTAPP1(shWTAPP1).Then,colony formation assay and CCK-8 assay were used to assess the proliferation of SK-NEP-1 cells,wound healing assay and Transwell assay were used to evaluate the migration and invasion activity of SK-NEP-1 cells respectively,and Western blotting was used to examine the relative expression levels of Wnt3a,β-catenin,C-myc and Survivin proteins. Results:The relative expression level of WTAPP1 in cancer tissues was higher than that in adjacent tissues(P<0.05).The relative expression level of WTAPP1 in SK-NEP-1 cells was higher than that in normal renal epithelial cells(PCS-400-01 0,PCS-400-01 1 and PCS-400-01 2;P<0.05).WTAPP1 expression was associated with the clinical stages of nephroblastoma(P<0.05)but not with the age,gender,tumor diameter or lymph node metastasis of nephroblastoma patients(all P>0.05).The 5-year survival rate of WTAPP1-high patients was significantly lower than that of WTAPP1-low patients(P<0.05).The proliferation,migration and invasion activities of SK-NEP-1 cells were significantly increased after WTAPP1 overexpression(all P<0.05)while decreased after WTAPP1 silencing(all P<0.05).The relative expression levels of Wnt3a,β-catenin,C-myc and Survivin proteins were significantly upregulated after WTAPP1 overexpression(all P<0.05)while decreased after WTAPP1 silencing(all P<0.05). Conclusion:WTAPP1 is correlated with the clinical stages and prognosis of nephroblastoma patients and may promote the proliferation,invasion and migration of tumor cells by activating Wnt/β-catenin signaling pathway.
RESUMO
An ultra-high performance liquid chromatography-tandem mass spectrometry(UHPLC-MS/MS) method was established to investigate the pharmacokinetic behaviors of psoralenoside, isopsoralenoside, calycosin-7-glucoside, ononin, psoralen, isopsoralen, methylnissolin, and neobavaisoflavone in rat plasma after oral administration of Bufei Huoxue Capsules. After SD rats were administered with Bufei Huoxue Capsules suspension by gavage, blood samples were collected from the inner canthus at different time points. After protein precipitation, plasma samples were separated on ACQUITY UPLC BEH C_(18) column(2.1 mm×100 mm, 1.7 μm). The mobile phase consisted of acetonitrile(A) and water(B) containing 0.1% formic acid in gradient elution. The positive and negative ions were measured simultaneously in the multi-reaction monitoring(MRM) mode. The pharmacokinetic parameters were calculated and fitted by DAS 3.2.8. Psoralenoside, isopsoralenoside, calycosin-7-glucoside, ononin, psoralen, isopsoralen, methylnissolin, and neobavaisoflavone were detected in the rat plasma after drug administration, with AUC_(0-t) of(3 357±1 348),(3 555±1 696),(3.03±0.88),(2.21±0.33),(1 787±522),(2 295±539),(5.69±1.41) and(3.40±0.75) μg·L~(-1)·h, and T_(max) of(1.56±0.62),(1.40±0.70),(0.21±0.05),(0.25±0.12),(0.26±0.11),(0.34±0.29),(0.74±0.59), and 0.25 h. The method is proved specific and repeatable and is suitable for the determination of psoralenoside, isopsoralenoside, calycosin-7-glucoside, ononin, pso-ralen, isopsoralen, methylnissolin, and neobavaisoflavone in the rat plasma, which can be applied to pharmacokinetic study.

Objective:To evaluate the clinical value of lymph node dissection (LND) for intrahepatic cholangiocarcinoma (ICC) after surgical resection.Methods:A retrospective study was conducted on the clinical data of 156 patients who underwent surgery for ICC in Eastern Hepatobiliary Surgery Hospital of Naval Military Medical University from November 2010 to December 2017, including 94 males and 62 females, aged (60.0±9.5) years. Curative surgery was performed in 114 cases. Of 64 cases were in stage Ⅰ according to American Joint Committee on Cancer (AJCC), including 38 cases of non-lymph node dissection (NLND) and 26 cases of LND; 21 cases were in AJCC stage Ⅱ, including 11 cases of NLND and 10 cases of LND; 22 cases were in AJCC stage Ⅲb, including 14 cases of LND and 8 cases of lymph node resection (LNR); 5 cases were in AJCC stage Ⅲa, 2 cases were in AJCC stage Ⅳ. Univariate and multivariate Cox regression analysis were used for the risk factors of ICC prognosis. The log-rank test compared the survival rates of the two groups.Results:Cox multivariate analysis indicated that lymph node metastasis was independent risk factors for prognosis in patients with ICC ( HR=1.96, 95% CI: 1.09-3.55, P=0.026). A total of 114 patients were included in the curative surgery group. The 1-, 3-, and 5-year overall survival (OS) rates of the negative lymph node group ( n=91) were 65.9%, 47.3% and 35.6%, respectively, which were significantly better than those of the positive lymph node group ( n=23) who had 1-, 3-, 5-year OS rates of 56.5%, 17.7% and 0, respectively (χ 2=8.11, P=0.004 ). In stage Ⅰ and Ⅱ patients, there were no significant differences in 1-, 3-, 5-year OS rates between the NLND group and the LND group (both P>0.05 ). In stage Ⅲb patients, the LND group had 1-, 3-, 5-year OS rates of 71.4%, 29.8% and 0, respectively, significantly better than those of the LNR group who had 1-, 3-, 5-year OS rates of 37.5%, 0 and 0, respectively (χ 2=6.45, P=0.011). Conclusions:Lymph node metastasis is an independent risk factor affecting the prognosis of ICC. Lymph node dissection should be performed cautiously in ICC with AJCC stage Ⅰ and Ⅱ, while routine lymph node dissection is recommended in ICC with AJCC stage Ⅲb.
RESUMO
Inflammatory bowel disease (IBD) is a chronic and recurrent inflammatory disease of gastrointestinal tract, including Crohn's disease and ulcerative colitis. The exact etiology and pathogenesis of IBD are still not clear. Neutrophil gelatinase-associated lipocalin (NGAL) plays an important role in regulating intestinal immunity, maintaining intestinal epithelial cell barrier, and coordinating the composition of intestinal flora. In addition, NGAL is useful for helping the clinical testing of IBD. This article reviewed the research progress of NGAL in IBD.

OBJECTIVE: To analyze the active surveillance results of occupational pneumoconiosis(hereinafter referred to as “pneumoconiosis”) in Beijing in 2019. METHODS: A total of 2 634 dust exposed workers were recruited as the active surveillance subjects by judgment sampling method. The abnormalities and influencing factors of High kV or digital photography of posterior-anterior chest radiography(hereinafter referred to as “chest radiography”) and lung function were analyzed. RESULTS: The detection rate of abnormal chest radiograph and pulmonary dysfunction were 14.0%(368/2 634) and 6.6%(175/2 634), respectively. The multivariate logistic regression analysis showed that the risk of abnormal chest radiograph in dust-exposed workers increased with age(P<0.01). Mining and construction workers had higher risk of abnormal chest radiograph than manufacturers(all P<0.05). The risk of abnormal chest radiograph of dusk-exposed workers in state-owned and foreign enterprises was higher than that of workers in private enterprises(P<0.05). The risk of pulmonary dysfunction was increased with age and length of dust exposure(all P<0.05). Workers exposed to silica dust and aluminum dust had higher risks than those exposed to welding dust(all P<0.01). The risk of pulmonary dysfunction of workers in small and micro enterprises was higher than that of workers in large enterprises(all P<0.01). Mining workers had higher risks of pulmonary dysfunction than manufacturing workers(P<0.05). CONCLUSION: Age, length of dust exposure, dust type, industry type, enterprise scale and economic type were the influencing factors of lung injury of dust exposed workers. Therefore, the supervision of key population and industries should be strengthened to reduce the occurrence of pneumoconiosis.
RESUMO
In order to improve teachers' teaching ability and manage teachers effectively, we try to organize teachers to carry out a series of activities in the form of "teaching club". We set up six teaching clubs according to the key points of teaching work and teaching hot spots. We explore the formation of "teaching club" as a means of modern teacher management model, through the implementation of the teacher-centered concept, establish an efficient and flexible management system, and establish and improve the active development of behavior and other strategies. Through a period of practice and exploration, we have gained benefits and even made breakthroughs in many aspects, such as the construction of teaching team, curriculum construction and teaching competition. The management strategies mentioned above provide new ideas for the development of teacher management.
RESUMO
Background: Matrix metalloproteinase-7 (MMP-7), a member of the MMPs family, is expressed in injured mucosal epithelial cells of many organs. Syndecan-1 (SDC-1), a substrate of MMP-7, plays an important role in tissue repair and maintaining intestinal barrier function. Aims: To investigate the expressions and significance of MMP-7 and SDC-1 in inflammatory bowel disease (IBD). Methods: Forty-five intestinal mucosa samples and fifty peripheral blood samples from inpatients with active IBD were collected during Jan. 2017 to Jan.2018 at the Second Affiliated Hospital of Zhengzhou University. Thirty intestinal mucosa samples and thirty-five peripheral blood samples from non-IBD subjects were served as controls. Expressions of MMP-7 and SDC-1 in intestinal mucosal tissue were detected by immunohistochemistry, and serum SDC-1 level was determined by ELISA. Results: MMP-7 was highly expressed in intestinal mucosal tissue of IBD patients, especially in mucosal epithelium bordering the ulcer area. Compared with control group, the expression of MMP-7 was significantly increased and that of SDC-1 was significantly reduced in intestinal mucosal tissue of IBD patients (P<0.05). In contrast, the serum level of SDC-1 was significantly increased in IBD patients (P<0.05). Spearman correlation coefficient analysis revealed a positive correlation between MMP-7 expression and the disease activity of IBD (rs=0.519, P<0.05 for ulcerative colitis; rs =0.583, P<0.05 for Crohn's disease), and a negative correlation between MMP-7 and SDC-1 in inflamed mucosa (rs=-0.646, P<0.05). Conclusions: Increased MMP-7 expression in intestinal mucosal tissue may contribute to the initiation and development of IBD via cleaving SDC-1 and impairing mucosal healing.
RESUMO
Objective: To explore the clinical characteristics, diagnosis, treatment and prognosis of patients with hematological diseases that complicated by mucormycosis, and to improve the understanding and clinical diagnosis and treatment of the disease. Methods: The clinical data of 7 patients suffering from mucormycosis during September 2012 and September 2018 were retrospectively analyzed, and their clinical characteristics, treatment process and prognosis were analyzed. Results: Of 7 patients, there were 4 males and 3 females, with a median age of 36 (19-79) years old. Two patients were diagnosed as acute myeloid leukemia as the underlying disease, the other 5 patients suffered from acute B lymphoblastic leukemia, peripheral T cell lymphoma, chronic myelocytic leukemia in blastic phase, myeloproliferative neoplasm and severe aplastic anemia after transplantation, respectively. Among them, disease types of mucormycosis were pulmonary in 4 patients, rhino-orbital-cerebral in 1 patient, cutaneous in 1 patient and disseminated in 1 patient. All the cases were confirmed by biopsy histopathology. The treatment drugs were amphotericin B or liposomal amphotericin B, and posaconazole. Surgical treatment was performed in 4 patients, 3 out of 4 achieved radical debridement, and the other one had local debridement. Two patients were cured, 1 patient was improved and 4 patients died. Conclusions: The clinical manifestation and image feature of mucormycosis in patients with hematological diseases were diverse, and the mortality rate is high, diagnosis mainly depends on histopathology. Early diagnosis, control of underlying disease, improvement of immunosuppressive status, timely effective antifungal therapy and radical surgical debridement are the key points for improving the survival rate of patients with hematological diseases complicated by mucormycosis.

Objective To observe the effectiveness of injecting mouse nerve growth factor ( mNGF) on the recovery of hand motor function among patients with cubital tunnel syndrome. Methods A total of 138 patients with moderate to severe cubital tunnel syndrome were randomly divided into groups designated as A, B and C, each of 46. Twenty micrograms of mNGF was injected daily 1 mm from the ulnar nerve at the cubital tunnel for the patients of group A and the injection site was moved 1 mm distally everyday along the nerve , but injected intramuscularly for those in group B. Those in group C received 500 μg of mecobalamin injected intramuscularly 3 times a week. The whole intervention consisted of two 4-week phases, with an interval of 2 months. Before and after the intervention, the function of internal hand muscles, hand function recovery rates and any electrophysiological changes in the ulnar nerve were measured and compared between the two groups. Results All of the patients showed significant improve-ment in hand muscle function and neuroelectrophysiology. The incidence of had muscle atrophy, Tinel′s sign, posi-tiveness in the paper clamping test and claw hand all significantly improved compared with before the treatment in all three groups. The average Disability of Arm Shoulder and Hand score in group A after the treatment was significantly higher than the group B and group C averages. The average ulnar nerve conduction velocity, incubation period and amplitude of group A after the treatment were all significantly better than before the treatment and better than the other groups′averages. After the treatment, the average hand function recovery in group A reached 91%, significantly high-er than in groups B ( 76%) and C ( 59%) . Conclusion Injecting mNGF next to the ulnar nerve is superior to in-jecting it intramuscularly in promoting the recovery of the ulnar nerve and hand function for patients with moderate to severe cubital tunnel syndrome.

RESUMO
The cervical epithelium can be affected by vaginal microecosystem inevitably, for the specificity of the cervical anatomy.HPV infection and cervical cancer,as well as vaginitis are associated with the imbalance of vaginal microecosystem.High-risk HPV infection is closely related to cervical cancer and precancerous lesions,with HPV16 and HPV18 causing 70%cervical cancer worldwide.Therefore,HPV test is significant in cervical cancer screening and follow-up.However, HPV test is used for cervical cancer or precancerous lesions detection clinically.In consequence, a threshold of HPV test for CIN2 +lesions evaluation should be set.In conclusion, it is important to understand the relationship among vaginal microecosystem,HPV infection and cervical cancer and precancerous lesions.Clinicians should know the purpose of HPV detection, which will contribute to clinical diagnosis and treatment of cervical cancer and precancerous lesions.(Chin J Lab Med,2018,41:267-269)
RESUMO

RESUMO
@#Mineral Trioxide Aggregate (MTA) is a biocompatible, antibacterial, radiopaque, and dimensionally stable material after setting. Furthermore, it can set in the presence of moisture, and has a high sealing ability. The objectives of this study were to describe managements of three different exceptionally complicated endodontics cases using MTA, and to evaluate its outcomes of using MTA in long-term follow-up based on modern concept of endodontics. Case #1: A 23-year-old patient diagnosed with combined endodontic-periodontal lesion with palatogingival groove of maxillary right lateral incisor was referred to our department. A treatment of interdisciplinary approach involving root canal treatment, periodontal initial therapy, root resection, guided tissue regeneration and bone grafting was performed. The case showed complete clinical normalcy and radiographic healing on periapical radiograph after 3-year follow-up, and outcome was defined as healed. Case #2: A 33-year-old patient had a perforated resorptive lesion to mesial external root surface of tooth 21. The diagnosis was perforating internal root resorption with pulp necrosis and asymptomatic apical periodontitis. A treatment plan of revascularization with MTA coronal plug was made. The case #2 showed clinical normalcy, complete healing of alveolar bone and incomplete healing of resorptive area radiolucency on CBCT after 4-year follow-up, and outcomes were defined as healing. Case #3: An 18-year-old patient with pulp necrosis and chronic apical abscess at immature left maxillary lateral incisor with open apex received treatment of apexification with MTA and followed-up regularly. The case showed complete clinical normalcy and radiographic healing on periapical radiograph, but incomplete healing of the periapical lesion was observed on CBCT after 4-year follow-up. This outcome was defined as healing. 1. MTA may be a suitable material for use as a plug material that prevents infection and blood flow to the main root canal during periodontal surgery, perforation repair and internal root resorption filling and root canal obturation of apexification treatment. 2. Extruded MTA through the apical foramen may not have an adverse effect to periapical tissues, also could be result in osseous healing. Moreover, extruded MTA might have a property to resorb. 3. Tooth discoloration could be a potential drawback of white MTA when it is used as endodontic repair material and the discoloration tends to continuously develop for a while.
