Objective The study aimed to explore the application of fast track surgery in nursing of patients with colon cancer in a primary hospital.Methods The 60 colon cancer patients were identified with numbers to indicate randomization into the fast tract surgery group (group A) and the conventional treatment group (group B) with 30 cases in each group.Group A used the concept of fast track surgery (FST) perioperative nursing care,whereas traditional perioperative nursing care for colon cancer was used in group B.Patients in both groups were observed for postoperative time for passage of gas by anus,time for first food intake,length of stay in hospital,fee for hospitalization as well as incidence of postoperative complications,and comparative analysis was carried out.Results Time for passage of gas by anus(t value was 3.571),time for first food intake (t value was 8.944),length of stay in hospital (t value was 3.397),fee for hospitalization (t value was 3.950) as well as incidence of postoperative complication in group A were lower than those of group B.The satisfaction degree of group A was 96.67％(29/30) while 83.33％(25/30) in group B and the satisfaction degree between the two groups was statistically significant.Conclusions In the primary hospital,the fast track surgery care used in colon cancer can not only speed up the recovery process of the patients,shorten hospital stay,reduce hospital cost and the incidence of postoperative complications,but also can reduce the workload of nurses and improve the satisfaction degree of patients.

Objective To elucidate the function and regulatory mechanism of LyGDI involved delayed cell death in the human K562 cells and HL-60 cells induced by 60Co γ-rays. Methods Erythrosine B cells staining was used to count the apoptosis rate. PI staining and flow cytometry were applied to check the cell cycle. The expression of LYGDI and Rac1 was resolved by Western blot by using monoclonal antibody of LyGDI and Racl. The distribution of Racl protein in cells was observed with immunofluorescence by using the confocal microscope. Results The K562 cells showed G2/M phase arrest and the percent age was 71.3%. The apoptosis rate was very low at early post-irradiation stage in the K562 cells. The apoptosis rate was 14% in the K562 cells at 24 h post-irradiation with 8 Gy of γ-rays, and delayed cell apoptosis was present. LyGDI was cleaved in the K562 cells irradiated by 4 Gy 60 Co γ-rays after 24 hours post-irradiation. The expression of Racl protein was not altered at all, but the distribution was changed in the irradiated cells while the Racl protein moved to cell membrane and a little in cell nucleus. The Racl was activated with the losing the binding affinity with the LyGDI. Conclusion LyGDI could promote the delayed cell apoptosis, which is through the activation of the Rac1.

Objective To assess the dignosis value of CT three-dimensional reconstruction with Fisher discriminant model in small solitary pulmonary nodules before operation.Methods CT data of 40 cases with SPN were retrospectively analyzed and divided into into malignant pulmonary nodules (25 cases),squamous cell carcinoma (4 cases),adenocarcinoma (13 cases),lung cancer (4 ca-ses),small cell lung cancer (2 cases),large cell carcinoma (1 case),metastases tumor (1 case),benign nodules (1 5 cases,6 cases of tuberculosis,2 cases of hamartoma,and 7 cases of non-specific inflammatory nodules)by pathology and follow-up results.The CT features of pulmonary nodules were evaluated through multi-planar reformation (MPR),curved-planar reformation (CPR),volume rendering (VR),maximum intensity proj ection (MIP)and other three-dimensional reconstruction.The three-dimensional data were divided into benign and malignant groups.In each of the two groups,the significant signs of morphological signs of discrimination indicators were adminstrated Fisher discriminant,and the probalitiy of false positives were estimated using cross-validation method. Results The positive features of pulmonary nodules in there-dismensional images were much more than in two-dimensional images. Fisher discriminant formula of solitary pulmonary nodules in three-dimensional images was Z=1.143X1 + 0.454X2+1.606X3-0.262X4+0.04X5+0.483X6+1.611X7-2.164.Discriminant boundary value Zc was-0.516.When Zcgreater than -0.516,nodules were proneed to considere as malignant nodules.In 25 cases of malignant nodules,4 cases mistook for benign.When Zc less than -0.516,nodules were proneed to considere as benign nod-ules.In 1 5 benign nodules,2 cases mistook for malignant.The total misdiagnosis and accuracy rate were 15 % and 85% respec-tively.Conclusion CT three-dimensional reconstruction combined with Fisher discriminant model have a high clinical value in dif-fereiating diagonsis of pulmonary nodules were proneed to considere as malignant nodules.In 25 cases of malignant nodules,4 cases mistook for benign.When Zc less than -0.516,nodules were proneed to considere as benign nodules. In 15 benign nodules,2 cases mistook for malignant.The total misdiagnosis and accuracy rate were 15 % and 85% respec-tively.Conclusion CT three-dimensional reconstruction combined with Fisher discriminant model have a high clinical value in differeiating diagonsis of pulmonary nodules.

Objective:To study the clinical manifestations, diagnostic methods and therapeutic outcomes of transverse testicular ectopia (TTE).Methods:Clinical data of 8 cases of TTE treated in the Department of the First Urologic Surgery, Xinxiang Central Hospital and Department of Pediatric Surgery, the First Affiliated Hospital of Zhengzhou University from May 2004 to November 2018 were retrospectively analyzed.Clinical manifestations, diagnostic methods, surgical treatment and follow-up results of TTE were summarized.Results:The age of 8 cases of TTE was 1 year 5 months to 5 years.Among the 8 cases of TTE, 6 cases were involved with the left side and 2 cases with the right side.All patients were admitted due to scrotal emptiness.Three cases were combined with persistent Müllerian duct syndrome (PMDS) and 1 case combined with hypospadias.Preoperative diagnosis of TTE was definitely made in 5 cases, involving 4 cases diagnosed by ultrasound and 1 case diagnosed by magnetic resonance imaging.Laparoscopy was performed in 2 cases, including 1 case treated with laparoscopic scrotopexy, and the other one transferred to an open surgery of trans-septal orchiopexy due to poor development of the spermatic cord.Open surgery was performed in 6 cases, including 1 case with bilateral testicular fixation in the ipsilateral scrotum due to adhesion of spermatic cord closely, and 5 cases with trans-septal orchiopexy.Müllerian ducts residues were excised during surgery in 3 cases combined with PMDS.Postoperative wound infection or hematoma was not reported in all cases.Orchiepididymitis and the involvement of contralateral testes occurred in 1 case treated with trans-septal orchiopexy at 11 months postoperatively, which were relieved after anti-inflammatory treatment.All cases were postoperatively followed up for 3-48 months, and the development and blood supply of bilateral testes were detected normal by ultrasonography.Postoperative testicular atrophy was not reported.Conclusions:The possibility of TTE should be considered in patients with unilateral cryptorchidism combined with contralateral inguinal mass.Ultrasonography is preferred to the diagnosis of TTE.Laparoscopic surgery plays an important role in the diagnosis and treatment of TTE, which is helpful to identify abnormalities in the Müllerian duct structure.

Mast cells are the main effector cells in allergic diseases. Allergic diseases are mostly a direct result of mast cell mediator release effects, while allergen activation is only one of many triggers for mast cell mediator secretion. Increased mast cell number, high mast cell reactivity, or both can lead to abnormal mast cell activation. Mast cell activated syndrome (MCAS) refers to a group or a"spectrum"of mediator-related, symptomatically similar diseases in which mast cells are stimulated by multiple factors. The symptoms and signs of mast cell disease overlap with allergic diseases, but the etiology is different, which requires clinical attention. This article summarizes the research progress on mast cell activation syndrome in recent years thus increase awareness of the differential diagnosis.

The prevalence of allergic diseases has gradually increased worldwide along with the development of industrialization, changes in environmental factors, adjustment of people′s diet structure and increasing exposure to allergens. Allergic diseases have become an important challenge to global public health strategies. Meanwhile, the coexistence with allergic rhinitis, and(or) allergic asthma, and(or) atopic dermatitis and other allergic diseases in a single patient is becoming more and more prevalent. Allergic comorbidities and multimorbidities will inevitably increase the difficulty of treating and recovery, seriously affect patients′ quality of life, and greatly increase the burden on social medical insurance. Understanding the underlying mechanisms of comorbidities and multimorbidities has both preventive and therapeutic significance. This article reviews the research progress of allergy comorbidity and multimorbidity in order to address the importance of this phenominon, stimulate clinical attention and provide a reference for the formulation of prevention and treatment strategies.
