Haiying Liu, Kun Wang, Qigang Wang, Shudong Sun, Youxin Ji
Journal of Medical Case Reports , 2011, DOI: 10.1186/1752-1947-5-373
Abstract: We present the cases of eight patients, two Chinese women and six Chinese men. The first Chinese woman was 36 years old, with 70% body surface area second or third degree flame burn injuries involving her eyelids on both sides. The other Chinese woman was 28 years old, with sulfuric acid burns on her face and third degree burn on her eyelids. The six Chinese men were aged 21, 31, 38, 42, 44, and 55 years, respectively. The 38-year-old patient was transferred from the ER with 80% body surface area second or third degree flame burn injuries and third degree burn injuries to his eyelids. The other five men were all patients with flame burn injuries, with 7% to 10% body surface area third degree burns and eyelids involved. All patients were treated with a modified surgical procedure consisting of separation and loosening of the musculus orbicularis oculi between tarsal plate and septum orbital, followed by grafting a large full-thickness skin graft in three days after burn injury. The use of our modified surgical procedure resulted in 100% successful eyelid grafting on first attempt, and all our patients were in good condition at six-month follow-up.This new surgical technique is highly successful in treating eyelid burn injuries, especially flame burn injuries of the eyelid.Eyelid involvement is common in facial burns. Treatment of eyelid burn injuries requires great care for the protection of the cornea. Burns damage tissues primarily by denaturing and coagulating cellular proteins and through vascular ischemic damage [1]. The most common etiologic agents of eyelid burns include local thermal and chemical burns and systemic burns [1,2]. Patients with burns involving the face often also have burns to the eyelids. Approximately 15% to 20% of patients with facial burns exhibit ocular injury. Most eyelid burns are the result of exposure to fire. In developing countries, 80% of chemical burns were due to industrial and/or occupational exposure. Approximately 60% of eyelid

Chinese Journal of Lung Cancer , 2009,
Abstract: Background and objective Chemerin was recently found a chemoattractant just like a chemotatic factor. It can induce immune chemotaxis to dendritic cells and macrophages by binding to its receptor ChemR23. It has been known that the activation of Chemerin could enhance the phagocytosis and antigen presentation of APC. Along with this observation, the contribution of Chemerin in the genesis and development of a tumor attracts more attention. We explored the relation between Chemerin and lung cancer through detecting the expression of Chemerin in peripheral blood of patients. Methods The experiment selected samples of lung cancer patients and normal people. The concentration of Chemerin in peripheral blood was detected by ELISA method. T test was used to compare the statistic difference. We compared the concentration of Chemerin in peripheral blood with age, sex, pathological type, degree of differentiation, metastasis of lymphonode, UICC staging and other clinicopathological index, and analyzed by t test and one-way ANOVA. Results The concentration of Chemerin in peripheral blood of 42 patients with lung cancer (1 965.81 pg/mL±374.03 pg/mL) were significantly higher than the concentration of 31 healthy examination (1 111.44 pg/mL±250.72 pg/mL)(P < 0.001). The concentration of Chemerin in peripheral blood of patients with lung cancer had no relationship with clinicopathological factors. Conclusion Chemerin has the potential to lung cancer diagnosis as a marker.

Song Bao, Dongbei Wu, Qigang Wang, Teng Su
PLOS ONE , 2014, DOI: 10.1371/journal.pone.0088802
Abstract: Developing the application of high-strength hydrogels has gained much attention in the fields of medical, pharmacy, and pollutant removal due to their versatility and stimulus-responsive properties. In this presentation, a high-strength freestanding elastic hydrogel membrane was constructed by clay nanosheets, N, N-dimethylacrylamide and 2-acrylamide-2-methylpropanesulfonic acid for adsorption of methylene blue and heavy metal ions. The maximum values of elongation and Young’s modulus for 0.5% AMPSNa hydrogel were 1901% and 949.4 kPa, respectively, much higher than those of traditional hydrogels. The adsorptions were confirmed to follow pseudo-second kinetic equation and Langmuir isotherm model fits the data well. The maximum adsorption capacity of hydrogel towards methylene blue was 434.8 mg g?1. The hydrogel also exhibited higher separation selectivity to Pb2+ than Cu2+. The methylene blue adsorbed onto the hydrogel membrane can be photocatalytically degraded by Fenton agent and the hydrogel membrane could be recycled at least five times without obvious loss in mechanical properties. In conclusion, this presentation demonstrates a convenient strategy to prepare tough and elastic clay nanocomposite hydrogel, which can not only be applied as recyclable membrane for the photocatalytic degradation of organic dye, but also for the recovery of valuables.
A New Variant of Combined Pulmonary Fibrosis and Emphysema from Long-Term High-Dose of Glucocorticoid Therapy: A Case Report  [PDF]
Qigang Zeng, Chenxia Duan, Yong Dai
Case Reports in Clinical Medicine (CRCM) , 2017, DOI: 10.4236/crcm.2017.612035
Abstract: Recent studies have described the combination of both pulmonary emphysema and idiopathic interstitial lung disease (ILDs) by means of high-resolution computed axial tomography (HRCT). Definition of this syndrome was first named by Cottin as combined pulmonary fibrosis and emphysema (CPFE). Functional and radiological findings have showed that these patients are suffering from severe breathlessness, but whose pulmonary functional tests revealed no signs of obstruction, normal static lung volumes, and depressed DLco, most with a history of smoking [1] [2]. The radiological and endoscopic studies especially show that these patients have both areas of upper-lobe predominant emphysema and lesions compatible with fibrosis in both lung bases [3]. No prior research has reported any cases of such condition in person with no prior history of smoking as well as long-term high-dose of glucocorticoid therapy. In this case report, we discuss the presentation, diagnosis, and management of a 53-year-old non-smoker with increasing shortness of breath with a long-term high-dose of glucocorticoid therapy discovered to have an abnormal variant or presentation of CPFE. The cause of disease was attributed to a certain history of smoking in most studies; other potential risk factors have yet to be properly analyzed. This clinical report features a special case about the problem and solution surrounding this issue.
