ObjectiveTo study the etiology, pathogenesis, clinical manifestations, diagnosis, treatment and prognosis of hemophagocytic syndrome (HPS). MethodsBetween February 2011 and October 2013, the causes, clinical manifestations, treatment and prognosis of 12 cases of HPS were retrospectively analyzed, and related literatures were reviewed. ResultsThere were 4 males and 8 females aged from 23 to 79 years old. Clinical features included fever (100.0%), lung infection (83.3%), enlarged lymph nodes (50.0%), bleeding (25.0%), splenomegaly (16.7%), and hepatomegaly (8.3%). Laboratory test results showed hemophagocytosis in bone marrow (100.0%), elevated ferritin (91.7%), thrombocytopenia (100.0%), decreased count in white blood cells (83.3%), decreased fibrinogen (66.7%), and hypertriglyceridemia (58.3%). Ten cases were related with infection, and 2 were related with diffused large B cell lymphoma. Nine patients died, 2 were cured, and one discharged himself from the hospital. ConclusionHPS is an uncommon disease, in which infection-associated HPS is the most common. The clinical presentation is complex, usually associated with multi-organ dysfunction, aggressive course, and high mortality rate.
Objective To observe the clinical effects of pars plana vitrectomy (PPV) combined with internal limiting membrane (ILM) peeling and C3F8 tamponade for patients with highly myopic macular hole (HM-MH) with and without foveoschisis. MethodsA retrospective case controlled study. From January 2017 to February 2022, 23 eyes of 23 patients with highly myopic macular hole with and without foveoschisis diagnosed in the Shandong Eye Hospital were included in the study. Among them, 5 males had 5 eyes, and 18 females had 18 eyes, the age was (54.43±12.96) years old. The patients with or without foveoschisis were 12 eyes in 12 cases and 11 eyes in 11 cases. Studies were divided into two groups, depending on the presence of a concomitant myopic foveoschisis or not. The groups are high myopia macular hole with foveoschisis (group A) and high myopia macular hole without foveoschisis (group B). Best-corrected visual acuity (BCVA), B-scan ultrasonography, optical coherence tomography and axial length (AL) measurement were performed in all eyes. Snellen chart was used for BCVA examination, and the visual acuity was converted into logarithm of minimum angle of resolution (logMAR) during statistics. The age of the two groups, sex, macular hole (MH) diameter, logMAR BCVA, AL, posterior scleral staphyloma, there was no significant difference (P＞0.05). PPV combined with ILM peeling and C3F8 filling were performed in all eyes. Follow-up was at least 3 months after the last operation. BCVA changes and MH closure were compared between the two groups after surgery. Wilcoxon test was used to compare BCVA before and after operation. Mann-whiteny U test was used to compare preoperative and postoperative BCVA between groups. ResultsAfter initial surgery, MH was closed in 17 of 23 eyes (74%, 17/23). MH was closed in 8 eyes in group A (66.7%, 8/12). Four eyes were not closed (33.3%, 4/12); MH closed in 9 eyes in group B (81.8%, 9/11). There was no significant difference between the two groups after initial operation (P＞0.05). At 1 and 3 months after surgery, the logMAR BCVA of patients in group A and group B were 1.00±0.46, 1.03±0.83 and 0.53±0.63, 0.55±0.41, respectively. Compared with before operation, there was no significant difference at 1 month (P=0.783, 0.358), but the difference was statistically significant at 3 months (P=0.012, 0.007). There was no significant difference in logMAR BCVA between group A and group B at 1 and 3 months after operation (P=0.687, 0.950). ConclusionPPV combined with ILM peeling and C3F8 tamponade can promote MH closure and improve visual acuity in most affected eyes with HM-MH with and without foveoschisis.
Objective To evaluate the efficacy and safety of perioperative comprehensive management in non- small cell lung cancer (NSCLC) with chronic obstructive pulmonary disease (COPD). Methods Clinical studies about effect of different perioperative comprehensive management on patients with early NSCLC combined with COPD were searched from PubMed, EMbase, The Cochrane Library, CBM, CNKI and WanFang databases from inception to November 1st, 2017. Two researchers independently screened literature, extracted data and evaluated the risk of bias of included studies, and then meta-analysis was conducted by RevMan 5.3 and Stata 14.0 softwares. Results A total of 20 articles were identified including 1 079 patients. The results of meta-analysis showed that perioperative comprehensive management improved the forced vital capacity (FVC), maximum minute ventilation (MVV), predictive value of postoperative one-second rate (ppoFEV1%), carbon monoxide diffusing capacity (DLCO) and percent forced expiratory volume in one second (FEV1%) (MD=–0.47, 95%CI –0.62 to –0.32, P<0.000 01; MD=–0.17, 95%CI –0.22 to –0.11, P<0.000 01; MD=–4.24, 95%CI –5.37 to –3.11, P<0.000 01; MD=–7.54, 95%CI –8.33 to –6.76, P<0.000 01; MD=–1.33, 95%CI –2.16 to –0.50, P=0.002; MD=–6.93, 95%CI –9.45 to –4.41, P<0.000 1, respectively). However, there was no significant difference in the rate of DLCO (DLCO%) and ventilation at maximal workload (VEmax) between pre- and post-management (MD=–2.91, 95%CI –11.31 to 5.50, P=0.5; MD= 0.18, 95%CI –2.23 to 2.58, P=0.89, respectively). With regard to cardiac function, perioperative comprehensive management improved the maximal oxygen consumption (VO2max), 6-minute walk distance (6MWD) and anaerobic threshold (AT) (MD=–2.28, 95%CI –3.41 to –1.15, P<0.000 1; MD=–57.77, 95%CI –77.90 to –37.64, P<0.000 1; MD=–2.71, 95%CI –3.30 to –2.12, P<0.000 1, respectively). As to complications, compared with conventional treatment group, perioperative comprehensive management group had fewer postoperative short-term complications (OR=0.39, 95%CI 0.26 to 0.58, P<0.000 01). Besides, perioperative comprehensive management also shortened hospital stay (MD=–2.38, 95%CI –3.86 to –0.89, P=0.002). Conclusion Perioperative comprehensive management can significantly improve lung function in patients with NSCLC combined with COPD, reduce short-term postoperative pulmonary complications and shorten the hospital stay with good efficacy and safety.
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.
