Objective To investigate the clinical characteristics, diagnosis and treatment of primary splenic tumors.Methods The clinical data of 47 patients with spleen tumors treated in the First Affiliated Hospital of Medical College, Xi'an Jiaotong University from January 2008 to October 2014 were retrospectively analyzed.Results 28 patients had no symptoms and only on physical examination was a mass found in some patients.There were 12 patients who manifested with upper abdominal discomfort or pain, 2 patients with an epigastric mass, l patient manifested with fever and 2 patients manifested with nausea and vomiting.Preoperative examination showed anemia in 7 patients.Three patients manifested with hypersplenism.Preoperative ultrasonic examination was performed on 39 patients with a diagnostic rate of 89.7％.43 patients underwent CT examination which had a diagnostic rate of 90.7％, MRI was performed in 4 patients and the diagnoses were all correct.Of the 47 patients with splenic tumor, 38 patients had a benign tumor.34 patients were treated by surgery, including 22 patients who underwent open splenectomy, 9 patients laparoscopic splenectomy, 3 patients laparoscopic fenestration of splenic cyst.Malignant tumors were found in 9 patients.Four patients underwent splenectomy, 2 patients were treated by laparoscopic splenectomy.Preoperative examination and postoperative pathological examination showed a benign tumor in 38 patients, including 1 1 patients with a splenic cyst, 6 patients with a cavernous hemangioma, 5 patients with an inflammatory pseudo tumor of spleen (accounting for 57.3％ of all the benign tumor).Malignant tumors included 5 patients with malignant lymphoma, 1 patient with splenic angiosarcoma, 1 patient with gastric carcinoma which metastasizes to the spleen, 1 patient with cervical carcinoma metastasizing to the spleen and 1 patient with liver carcinoma metastasizing to the spleen.Adjuvant chemotherapy and (or) radiotherapy after surgery were performed for patients with malignant lymphoma of the spleen.For 2 patients who were diagnosed early, surgery combined with radiotherapy or chemotherapy and immunotherapy were alive for more than 18 months.Conclusions The clinical manifestations of splenic tumors lack specificity.The diagnosis mainly depends on ultrasonic examination, CT and MRI.Early diagnosis, radical operation and comprehensive treatment are important to improve the prognosis of patients with malignant tumors of the spleen.

Objective To explore the clinical characteristics and perioperative treatment of chronic obstructive pulmonary disease (COPD) in patients with non-small-cell lung cancer (NSCLC) in department of thoracic surgery,and to guide the clinical diagnosis and treatment. Methods From January 2013 to December 2016,patients with newly diagnosed NSCLC treated in the thoracic surgical department of Lanzhou University Second Hospital were reviewed retrospectively. The patients were divided into the COPD group and non-COPD group. The clinical data,including the incidence and clinical characteristics of COPD in non-small-cell lung cancer,pulmonary complications after surgery,COPD diagnosis and perioperative pulmonary rehabilitation were analyzed retrospectively. Results A total of 726 NSCLC patients were reviewed,six hundred and seventy-five cases who took the full lung function test were included in the study,of which 95 cases received bronchial diastolic test,86 cases were accorded with COPD diagnosis and were included in incorporated COPD group,and 589 cases were in the non- incorporated COPD group. The proportion of men (69 cases,80. 2%,χ2 = 24. 032), age ≥65 (51 cases,59. 3%,χ2 = 6. 784),smoking history (55cases,64. 0%,χ2 = 29. 474) and a large number of smokers (43 cases,50. 0%,χ2 = 5. 802) and lung squamous cell carcinoma(47 cases,54. 7%,χ2 = 6. 241) in the incorporated COPD group were higher than those in differences were statistically significant (P<0. 05); the incidence of pulmonary complications after radical resection of lung cancer in the incorporated COPD group was 23. 9% (16/ 67),which was significantly higher than that in the unincorporated COPD group(13. 7% (78/568)) (χ2 = 4. 894,P<0. 05). The incidence of pulmonary complications in the lung rehabilitation group was 13. 5% ( 5/37) , lower than that of the non-lung rehabilitation group ( 36. 7% ( 11/30 ) ) (χ2 = 4. 886, P<0. 05);Among the 86 cases (12. 7%) of incorporated COPD,only 6 cases (8. 9 ‰) were diagnosed with COPD at the time of admission, and 23 cases ( 3. 4%) at discharge. No COPD guidelines were given. Conclusion NSCLC often combined wtith COPD,especially in males,elders (≥65 years old) ,smokers, squamous cell carcinoma patients. At present,the diagnosis and treatment of co-morbidity of COPD is seriously inadequate,which needs to be paid much attention to by the thoracic surgeons,in order to improve the diagnosis and treatment of COPD,and improve the prognosis of the patients with NSCLC and COPD.

Objective To explore the research state and topics of lung cancer with chronic obstructive pulmonary disease (COPD) in China using the visualization methods. Methods Literature about lung cancer with COPD was searched through WanFang, CNKI, CBM, PubMed, The Cochrane Library and EMbase databases from inception to March 2018 by computer. We used BICOMS software to analyze the main information and produce co-word matrix, gCLUTO software to cluster, and NetDraw and Cytoscape software to draw the pictures. Results There were 304 studies related to lung cancer with COPD which originated from 173 journals including 23 indexed by Chinese Science Citation Database (CSCD) with 42 articles published, accounting for 13.8% of the total number of studies. There were 37 articles from 24 journals indexed by Science Citation Index (SCI) accounting for 12.2% of the total number of studies. The studies grew rapidly since 2012. The study involved 32 provinces, municipalities, and autonomous regions, among which Beijing, Sichuan, Shanghai, Guangzhou and Jiangsu provinces and cities were the main research areas. Sixty-nine high-frequency keywords were obtained with frequency 2 as the threshold, which was clustered into 5 categories by dual cluster analysis. Among them, topic 0 showed pathogenesis and radiological diagnosis of lung cancer with COPD, topic 1 was about the clinical characteristics of different pathological types of lung cancer with COPD and Chinese medicine treatment, topic 2 aimed at the impact of risk factors on surgical complications and the relationship between chemotherapy or targeted therapies and patient survival prognosis, topic 3 involved the pigenetic correlation between lung cancer and COPD and topic 4 was about clinical studies of perioperative comprehensive management of lung cancer patients with COPD. Conclusion The bibliometrics results show that there are considerable-amount achievements on lung cancer combined with COPD in China, and the researches have gradually increased since 2012. Horizontal research topics are extensive, and the focus of the study is to explore the perioperative comprehensive management and basic research of lung cancer with COPD, but the longitudinal themes need to be further studied. The results of some studies have not yet reached a consensus. There are few high-quality multi-center studies and a lack of clinical-directed achievement.

OBJECTIVETo observe the multiple symptom distribution, severity and quality of life of female pelvic floor dysfunction(FPFD) patients with constipation as chief complaint.

METHODSOne hundred FPFD patients with constipation as chief complaint from Speciaty Outpatient Clinic, Pelvic Floor Center of Nanjing Municipal Hospital of Traditional Chinese Medicine between September 2015 and February 2017 were retrospectively enrolled in this study. A comprehensive medical history questionnaire survey and systematical evaluation of severity and quality of life of these patients with constipation was conducted. Constipation scoring system scale (CSS) and patient-assessment of constipation quality of life questionnaire (PAC-QOL) were applied to evaluate the constipation. Other scales included: (1)pain visual analogue scale (VAS) and short form-36 questionnaire (SF-36): if combined with chronic functional anal rectal pain; (2) international consultation on incontinence questionnaire-short form (ICIQ-SF) and urinary incontinence quality of life questionnaires (I-QOL):if combined with urinary incontinence; (3) fecal incontinence severity score scale (Wexner-FIS) and fecal incontinence quality of life questionnaire (FI-QOL):if combined with fecal incontinence.

RESULTSThe mean age of 100 FPFD patients was (57.9±13.9) (24-89) years and the mean disease course was (7.0±8.2)(0.5-40.0) years. Seventy-five cases (75%) were complicated with anal pain, 70 with urinary incontinence, 37 with rectocele, 19 with nocturia, 11 with urinary frequency, 10 with defecation incontinence. Complication with only one symptom was observed in 20 cases (20%), and with two or more symptoms was observed in 80 cases (80%). Pelvic floor relaxation syndrome patients were dominant (58 cases, 58%). The severity of constipation (CSS) was 6-22 (13.89±3.79) points and the quality of life (PAC-QOL) was 45-133 (87.13±18.57) points in FPFD patients. VAS and SF-36 of patients combined with chronic functional anal rectal pain were 1-8 (3.0±1.9) points and 14.4-137.0(71.5±31.4) points respectively. ICIQ-SF and I-QOL of patients combined with urinary incontinence were 1-17 (6.1±3.6) points and 52-110 (90.0±15.8) points respectively. Wexner-FIS and FI-QOL of patients combined with fecal incontinence were 1-11 (4.4±3.0) points and 52-116 (83.4±23.3) points respectively.

CONCLUSIONSThe symptoms of FPFD patients with constipation as chief complaint are complex. They are mainly complicated with anal diseases, then urinary incontinence, and mostly with more than 2 symptoms. Their quality of life is poor.
