Objective To investigate the diagnostic value and safety of thoracoscopy routine pleural biopsy combined with frozen biopsy for pleural effusion. Methods A retrospective analysis was made on the pathological diagnosis rate of pleural effusion. Results 120 cases in thoracoscopy, 103 cases were confirmed with routine biopsy specimens (85.8%), 16 cases found in the lesions with conventional clamp not satisfactory tissue specimens, combined with frozen cut obtained satisfactory specimens, the diagnostic accuracy rate of 16 cases of cryobiopsy was 100.0%, and the total diagnostic accuracy rate of medical thoracoscopy combined with pleural biopsy and cryobiopsy was 95.0%. There was significant difference between conventional biopsy and cryobiopsy (P < 0.05). Conclusion Medical thoracoscopy combined with pleural biopsy and cryobiopsy can achieve a higher rate of pathological diagnosis, and the complications are mild, so it is worthy of clinical promoting.

Objective To observe the effect of psychological intervention on nosohemia patients during hematopoietic stem cell collection technique. Methods 44 perioperative nosohemia patients were assigned to experiment group and control group. The experiment group took a psychological intervention. Results Anxiety and depression in the experiment group improved better than in the control group (P<0.05) while there was no significant difference in anxiety and depression in the control group after psychological intervention (P>0.05). Conclusion Psychological intervention could effectively reduced the negative emotion of perioperative nosohemia patients during hematopoietic stem cells collection.

This paper was to explore the relationship between plasma omentin and obesity and insulin resistance in patients of polycystic ovary syndrome(PCOS).The results showed that there were statistically significant differences in serum omentin levels among control group,PCOS-normal weight group,and PCOS-overweight group [(115.29 ± 33.92),(111.12 ± 34.50),and (42.85 ± 19.39) pg/ml,P＜ 0.05].Omentin were negatively correlated with homeostasis model assessment for insulin resistance(HOMA-IR) and body mass index(BMI).In the multiple stepwise regression analysis,only omentin was negatively correlated with BMI.Omentin may be involved in the development of PCOS by affecting obesity.

Objective To discuss combined detection of pleural biopsy under medical thoracoscopy and pulmonary serum tumor markers in diagnosis of pleural effusion with unknown reason.Methods 76 patients with pleural effusion caused by unknown reason from January 2014 to March 2016 were retrospectively analyzed. Pleural biopsy was conducted under medical thoracoscopy and sent for pathological examination, and 10 ml venous blood was collected from these patients upon admission for testing serum tumor markers (CEA, SCC-AG, ProGRP and CYFRA21-1).Results Among the 76 patients, there were 32 cases with benign lesions (14 with pulmonary tuberculosis, 9 with inlfammatory lesions, 6 with granulomatous inlfammation, 2 with empyema and 1 with hamartoma) and 44 cases with malignant lesions (18 with adenocarcinoma, 13 with squamous carcinoma, 6 with small cell lung cancer, 3 with adeno-squamous carcinoma, 2 with mesothelioma, 1 with large cell carcinoma and 1 with thymoma). The detection of serum tumor markers showed statistically significant differences in the levels of CEA, SCC-AG, ProGRP and CYFRA21-1 in serum between the malignant pleural effusion group and benign pleural effusion group (P = 0.021,P = 0.006,P = 0.003 andP = 0.010). The levels of various serum tumor markers in the malignant pleural effusion group were obviously higher than those in the benign pleural effusion group. According to the pathological results, patients with pleural effusions not caused by lung cancer (2 with mesothelioma and 1 with thymoma) were eliminated from 44 patients with malignant pleural effusions. The rest 41 patients with pleural effusions caused by lung cancer were divided into non-small cell lung cancer and small cell lung cancer according to the pathological types. The results showed that there were statistically signiifcant differences in the levels of CEA, ProGRP and CYFRA21-1 between non-small cell lung cancer and small cell lung cancer (P = 0.036,P = 0.005 andP = 0.008), while there was no statistically signiifcant difference in the level of SCC-AG (P = 0.811).Conclusions Due to high detection rate and high accuracy in detecting pleural effusions caused by unknown reason, medical thoracoscopy is of great signiifcance, especially for the diagnosis of malignant pleural effusions of pleural metastases. However, serum indicators may provide important reference values for us before the pathological results are available. Thus, it is an important means of diagnosing malignant pleural effusions caused by lung cancer and should be promoted in clinic.

Objective To analyze factors associated with the relapse of propranolol-treated infantile hemangioma.Methods The clinical data were collected from 235 children with infantile hemangioma who had discontinued propranolol for 6 months,and retrospectively analyzed.Factors for the relapse of propranolol-treated infantile hemangioma were analyzed by univariate and multivariate unconditional logistic regression analyses.Results Of 235 patients followed for 6 months after drug withdrawal,66 (28.1％) were identified to have recurrence of infantile hemangioma,of whom,15 (22.7％) had severe recurrence.The risk of recurrence was significantly increased in patients taking propranolol at a daily dosage of 1.5 mg/kg compared with those taking propranolol at a daily dosage of 2 mg/kg (OR =3.566,95％ CI:1.306-9.739),in patients aged ＞ 8 weeks at the initial drug treatment compared with those aged ≤ 8 weeks at the initial drug treatment (OR =5.043,95％ CI:1.248-20.376),in patients with the course of medication ≤ 6 months compared with those with the course of medication ＞ 6 months (OR =17.661,95％ CI:4.899-63.665),as well as in patients aged ＜ 1 year at drug withdrawal compared with those aged ≥ 1 year at drug withdrawal (OR =6.089,95％ CI:1.835-20.204).Conclusion There are many risk factors associated with the relapse of propranolol-treated infantile hemangioma,so some measures aimed at these risk factors should be taken to reduce the recurrence rate.
