摘要:目的: 探討PCNA,VEGF在胃癌組織中的表達關系及其意義。 方法 :免疫組織化學法檢測正常胃和胃癌組織中PCNA和VEGF的表達,并分析其與胃癌臨床病理特征的相關性。 結果 :胃癌組織中PCNA、VEGF的陽性表達率分別為850%、683%,二者在正常胃組織中均為隱性表達。PCNA的表達與腫瘤分期、淋巴結轉移有關(〖WTBX〗P lt;005),而與年齡、性別、腫瘤大小、組織分化程度無關(〖WTBX〗P gt;005);PCNA的表達與腫瘤分期、淋巴結轉移有關(〖WTBX〗P lt;005),而與年齡、性別、腫瘤大小、組織分化程度無關(〖WTBX〗P gt;005)。PCNA和VEGF在胃癌中的表達呈正相關。 結論 :PCNA和VEGF在胃癌組織中的高表達促進了胃癌的發生發展。Abstract: Objective: To study the significance and relationship of expression of proliferating cell nuclear antigen(PCNA) and vascular endothelial growth factor (VEGF) in gastric cancer. Methods : The expression of VEGF and PCNA in normal gastric tissues and gastric cancer tissues were detected by immunohistochemistry (SP),and clinic pathological correlation with gastric cancer was analyzed. Results : The positive exression rates of PCNA and VEGF in gastric cancer were 850%、683%, respectively, while negative expression was shown in normal gastric tissues. It was found that the expressions of PCNA and VEGF were both in significant relation to TNM stages and lymph node metastasis (P lt;005), but in no relation to age, gender, diameter of tumor and tumor cell differentiation (P gt;005). The expressions of PCNA and VEGF were positively correlated with each other. Conclusion : It was indicated that the highlevel expressions of PCNA and VEGF might corporately accelerate the progression of gastric cancer.
ObjectiveTo establish a forecasting model for inpatient cases of pediatric limb fractures and predict the trend of its variation.MethodsAccording to inpatient cases of pediatric limb fractures from January 2013 to December 2018, this paper analyzed its characteristics and established the seasonal auto-regressive integrated moving average (SARIMA) model to make a short-term quantitative forecast.ResultsA total of 4 451 patients, involving 2 861 males and 1 590 females were included. The ratio of males to females was 1.8 to 1, and the average age was 5.655. There was a significant difference in age distribution between males and females (χ2=44.363, P<0.001). The inpatient cases of pediatric limb fractures were recorded monthly, with predominant peak annually, from April to June and September to October, respectively. Using the data of the training set from January 2013 to May 2018, a SARIMA model of SARIMA (0,1,1)(0,1,1)12 model (white noise test, P>0.05) was identified to make short-term forecast for the prediction set from June 2018 to November 2018, with RMSE=8.110, MAPE=9.386, and the relative error between the predicted value and the actual value ranged from 1.61% to 8.06%.ConclusionsCompared with the actual cases, the SARIMA model fits well with good short-term prediction accuracy, and it can help provide reliable data support for a scientific forecast for the inpatient cases of pediatric limb fractures.
Objective To improve the knowledge of kartagener syndrome and the understanding of primary ciliary dyskinesia ( PCD) . Methods Three cases of Kartagener syndrome were reported and analyzed on clinical manifestations, symptoms, imaging appearances of chest, and family history. Meanwhile the related literatures were reviewed. Results The three patients deserved special recognition because of recurrent upper and lower respiratory tract infection. Of them, the third case showed mainly the symptoms of nasosinusitis at an early age, and the distinct pulmonary symptoms appeared in his adulthood. Further examination showed that the triad of chronic sinusitis, bronchiectasis, and situs inversus is present in all cases. The parents of the two cases were consanguineous marriaged. Examination of the bronchial mucosal biopsy specimen of the first case under transmission electron microscopy showed cilia with the absence of inner dynein arms. The three cases got improvement after treatment of anti-infection and expectorant. Conclusion For patients with recurring infection in the upper and lower respiratory tract from infancy, the possibility of PCD should be considered no matter whether a situs inversus exists.

ObjectiveTo explorer the risk factors for acute exacerbation in patients with bronchiectasis within one year.MethodsFour hundred and twenty-two patients with non-cystic fibrosis bronchiectasis hospitalized were enrolled in The East Region of the People’s hospital of Sichuan between October 2014 and October 2016. The patients’ clinical data were collected, and follow-up began at the time of discharged. The study endpoint was the first acute exacerbation, all patients were followed-up for one year after discharged. The patients were classified into two groups by the occurrence of acute exacerbation or no occurrence. Logistic regression analysis was used to explore the risk factors for acute exacerbation with bronchiectasis.ResultsThe age, sick time, body mass index (BMI) less than 18.5 kg/m2, smoking index, expectoration, hemoptysis, dyspnea, moist sounds, wheezing sounds, types of imaging, CT scores, lung lesion site, sputum culture, whether infected Pseudomonas aeruginosa, level of serum C-reactive protein (CRP), level of serum PCT, serum albumin, arterial carbon dioxide partial pressure, types of respiratory failure, combined with chronic cor pulmonale differed significantly between the two groups (P<0.05), while gender, history of Infection, smoking, cough, chest pain, fever, clubbed-finger, white blood cell counts, neutrophil counts, erythrocyte sedimentation rate, serum globulins, arterial oxygen partial pressure did not significantly differ (P>0.05). Multivariate Logistic regression analysis found that infection with Pseudomonas aeruginosa, BMI<18.5 kg/m2, high level of serum CRP, high level of arterial carbon dioxide partial pressure (PaCO2), high CT score with bronchiectasis, combination with chronic cor pulmonale were risk factors for acute exacerbation in patients with bronchiectasis (P<0.05).ConclusionsInfection with pseudomonas aeruginosa, BMI < 18.5 kg/m2, high serum CRP level, high arterial blood PaCO2 level, high CT score with bronchiectasis and combination of chronic cor pulmonale are risk factors for acute aggravation within 1 year for patients with bronchiectasis.

Methods PENTAX (EG-1580K) ultrafine nasal endoscopy was used in 28 patients (October 2007-March 2009) with esophageal cancer complicated with esophagostenosis and fistula to check the e-calculated insertion depth, stent expansion and the average diameter expansion. The endoscopy was carried under the direct vision with the location of the top bracket in order to ensure the accurate stent placement, all without X-ray assist. The success rates of stent placement, positioning accuracy, as well as complications were evaluated. Results The expansion treatments were successful in all patients with one-off operation. The narrowest part increased from (4.9±1.6) mm to (12.7±1.5) mm, and the esophageal fistula was covered. The rating of dysphagia decreased from 3.15±0.68 to 0.91±0.49. Conclusion Nasal endoscopy is simple, safe and effective in the treatment of ultrafine expansion for esophagostenosis and stent implantation with good compliance.
Objective To investigate the therapeutic effect of minimally invasive small incision surgery under local anesthesia for pediatric stenosing tenovaginitis of thumb. Methods A retrospective analysis was conducted on the medical records of children with stenosing tenovaginitis of thumb who received small incision tendinolysis under local anesthesia at West China Hospital of Sichuan University between January 2013 and August 2022, to evaluate and analyze the safety and effectiveness of the surgery. Results A total of 949 pediatric patients were included, with an average age of (3.23±1.92) years. The average duration of surgery was (7.0±2.5) minutes, and the average follow-up time was (3.91±5.32) months. All patients did not need to fast for solids and liquids before surgery, and were immediately discharged from the hospital after outpatient surgery. The family members of the patients were highly satisfied with the treatment process and postoperative recovery. All patients had no nerve or vascular damage, and the wound margin skin showed linear healing with mild scars that fused with palm prints. There were 825 cases (86.93%) of children with thumb function fully restored to normal, 113 cases (11.91%) with limited maximum dorsiflexion function of the thumb, and 11 cases (1.16%) with recurrent stiffness of the thumb metacarpophalangeal joint. Conclusion Small incision tendinolysis under local anesthesia is a safe and effective treatment for pediatric stenosing tenovaginitis of thumb, with high satisfaction among the patients’ family members.

Objective To summarize the etiology and clinical features of Mounier-Kuhn syndrome (MKS) so as to enhance the acknowledgement of MKS. Methods Three cases of MKS were reported and the keywords with " Tracheobronchomegaly”, " Mounier-Kuhn syndrome” were analyzed through the mode of literature retrieval in CNKI, VIP and Pubmed databases. Results There were 214 cases around the world including 14 cases of MKS in China. With unknown etiology and non-specific clinical feature, MKS is characteristic with congenital absence of tracheal or bronchial elastic tissue. MKS is diagnosed with remarkably dilated trachea and bronchus through chest CT or bronchofibroscope, accompanied with genetic defects. The ratio of men to women is 8.5 to 1. There is no radical cure. Symptomatic treatment and surgical treatment when necessary could be available. Conclusions MKS is a rare progressive hereditary disease, irrelevant to smoking and sharing a similar cause with generalized elastolysis, which need pay much attention to the physical examination of skin or elastic tissue. The diagnosis of MKS should be based on not merely airway diameter but also the overall clinical, pathologic, and radiologic profile.
