Objective: To investigate the clinical characteristics and the effectiveness of surgical treatment of adrenal cysts. Methods: The clinical data of adrenal cysts in Affiliated Zhangye people′s Hospital, Hexi College from May 2005 to July 2018 were retrospectively analyzed, including clinical manifestations, diagnosis, surgical methods, postoperative pathological results and follow-up process. Seventeen patients with adrenal cysts were identified including 10 males and 7 females. The median age was 45.6 ranging from 30 to 75. There were 12 left lesions and 5 right lesions. Only 4 patients (23.5%) had clinical symptoms, including low back pain, abdominal pain and dizziness caused by hypertension. Ultrasound, CT and MRI were the main imaging methods for preoperative diagnosis. Results: All patients underwent surgical treatment. Laparoscopic surgery was adapted in 14 cases. The average operation time was (70.2 ± 18.5) min and the average bleeding was (47.0 ± 12.1) ml. For open surgery in 3 cases, the average operation time was (103.5 ± 25.0) min and the average bleeding was (85.6 ± 20.5) ml. Postoperative pathological results showed endothelial cysts in 11 cases, epithelial cysts in 3 cases and pseudocysts in 3 cases. No recurrence of cysts or hypoadrenalism occurred in 3-75 months′ follow-up. Conclusions Adrenal cysts are relatively rare and generally benign lesions. Imaging examination, especially abdominal enhanced CT is essential for diagnosis. Laparoscopic surgery is a safe and effective method for the treatment of adrenal cysts.

Objective To investigate the clinical efficacy of rib's strapping-traction technology using absorbable implants combined with memory-alloy ribs embracing fixator in treating multiple rib fractures under video-assisted thoracoscope.Methods A retrospective case control study was performed to analyze 178 patients with multiple rib fractures treated from January 2015 to June 2017.According to the operation method,all patients were divided into observation group (91 patients) and control group (87 patients).The observation group including 59 males and 32 females aged (39.7 ± 7.8)years adopted internal fixation by rib's strapping-traction technology using absorbable implants combined with memory alloy ribs embracing fixator under video-assisted thoracoscopic surgery.The control group including 56 males and 31 females aged (40.2 ± 6.9) years adopted internal fixation by conventional rib's clamping-traction technology using towel forcep combined with memory-alloy ribs embracing fixator under video-assisted thoracoscopic surgery.The incision length,single rib internal fixation time,number of internal fixation rib fractures,visual analogue scale (VAS) score on postoperative 1 d,postoperative chest drainage,postoperative hospital stay,and postoperative fracture healing were compared between the two groups.Results All patients were followed up for 3-30 months (mean,16.7 months).All operations were successful,with no case of thoracotomy.The observation group had shorter incision length [(4.3 ± 1.2) cm vs.(6.2 ± 1.7) cm] and single rib internal fixation time [(10.3±2.9)min vs.(14.1 ±2.3)min] than the control group (P＜0.05).There were no significant differences (P ＞ 0.05) between the two groups in number of internal fixation rib fractures [(5.7±.3.6) vs.(5.9±3.3)],postoperative chest drainage [(668.3 ±131.4)ml vs.(703.7±116.2)ml],postoperative hospital stay [(6.4 ± 1.8) d vs.(6.8 ± 1.7) d],the VAS score on postoperative 1 d [0-3 point,62％ vs.61％;4-6 point,38％ vs.39％],postoperative osteophyte formation rate [postoperative 1 month,97％ vs.95％;postoperative 3 months,100％ vs.100％].Stable chest walls and thoracic deformity recovery were seen in all patients,with no significant complications occurred.Conclusion Rib's strapping-traction technology using absorbable implants combined with memory-alloy ribs embracing fixator under video-assisted thoracoscope is convenient and has exact efficacy for multiple rib fractures,with advantage of shorter incision length and operation time over conventional thoracoscopic surgery,and thus is worthy of clinical application.

Objective: To explore the association between Vitamin A, E and mycoplasma pneumoniae pneumonia in children. Methods: 153 children with mycoplasma pneumoniae pneumonia and 653 health children were selected as cases and controls, respectively. Propensity score matching (PSM) analysis were conducted to reducing confounding bias between groups. Blood samples were collected to test serum levels of vitamin A and E using high performance liquid chromatography (HPLC). Logistic regression was implemented to determine odds ratios (OR) and 95% confidence intervals (CI) for evaluating the association of mycoplasma pneumoniae pneumonia with the serum levels of Vitamin A and E. Results: After propensity score matching, the study cohort included 153 cases with mycoplasma pneumoniae pneumonia and 306 health children as controls. Before matching, with age and gender adjusted, logistic regression analysis indicated that higher serum levels of Vitamin A and E led to a lower risk of mycoplasma pneumoniae pneumonia (OR=0.075, 95% CI: 0.007-0.815; OR=0.854, 95% CI: 0.792-0.986). After matching, higher serum level of Vitamin E had a significantly lower risk of mycoplasma pneumoniae pneumonia (OR=0.877, 95% CI: 0.810-0.950). Conclusions The serum levels of Vitamin A didn't have a statistically significant association with mycoplasma pneumoniae pneumonia. However, we observed an obvious association between Vitamin E and mycoplasma pneumoniae pneumonia. Hence Vitamin E clinical monitoring and supplementation are vital for preventing and treating mycoplasma pneumoniae pneumonia.

Objectives: To evaluate the tumor-infiltrating PD-1 positive lymphocytes and regulatory T cells (Treg) as prognosis predic-tors of metastatic renal cell carcinoma (mRCC), and investigate the expression of PD-1 and Treg cells in mRCC and elucidate their corre-lation with clinicopathological parameters and prognosis. Methods: A total of 269 mRCC patients from June 2007 to June 2017 in Zhongshan Hospital, Fudan University, were included in the study. The expression of PD-1 and Tregs in mRCC samples were detected by immunohistochemistry. The relationship between the expression of PD-1 and Tregs was analyzed. Results: PD-1 positive expression in mRCC was 31.60% (85/269) and it was positively correlated with the tumor Fuhrman grade and negatively correlated with progno-sis. Tumor infiltration of Tregs in mRCC was 36.80% (99/269), and it was also positively correlated with the tumor Fuhrman grade and negatively correlated with prognosis. Univariate analysis showed that PD-1 positive lymphocytes and high Treg infiltration numbers were negatively correlated with overall survival (OS) and progression free survival (PFS) rates. Thus, PD-1 positive lymphocytes and high Treg infiltration numbers are independent prognostic indicators of OS and PFS and when combined, they can render a better pre-diction for prognosis. Conclusions: Intra-tumoral infiltration of PD-1 positive lymphocytes and Tregs can be used as significant prognos-tic indicators of mRCC, and the combined predictive effect is better than the individual predictive effect. Therefore, evaluating the number of PD-1 positive lymphocytes or infiltrating Tregs in mRCC is helpful in clinically estimating mRCC prognosis in patients.
