3.Long-term care policy in Japan and its implications for China
Chinese Journal of Health Policy 2014;(4):55-61
This paper reviews the long-term care policy in Japan and discusses successes and challenges in order to provide policy guidelines for China. All Japanese adults aged 65 or over are covered by the long-term care in-surance ( LTCI) program and are eligible for both in-home and institutional-care services following a thorough, sys-tematic care certification process. The program is financed by a mix of general tax revenues from the three levels of gov-ernment , income-tested premiums, and standardized co-payments. A key success of the policy is its universal and compre-hensive coverage. Notwithstanding this success, increasing costs remain a challenge as Japan’s population ages and the number of LTCI users increases. Learning from the experience of Japan, China should establish a long-term care system, which covers all the aged population, mainly focuses on in-home care, and qualifies social funding to invest.

5.Advances in the study of natural small molecular antibody.
Acta Pharmaceutica Sinica 2012;47(10):1281-6
Small molecule antibodies are naturally existed and well functioned but not structurally related to the conventional antibodies. They are only composed of heavy protein chains or light chains, much smaller than common antibody. The first small molecule antibody, called Nanobody was engineered from heavy-chain antibodies found in camelids. Cartilaginous fishes also have heavy-chain antibodies (IgNAR, "immunoglobulin new antigen receptor"), from which single-domain antibodies called Vnar fragments can be obtained. In addition, free light chain (FLC) antibodies in human bodies are being developed as therapeutic and diagnostic agents. Comparing to intact antibodies, common advantages of small molecule antibodies are with better solubility, tissue penetration, stability towards heat and enzymes, and comparatively low production costs. This article reviews the structural characteristics and mechanism of action of the Nanobody, IgNAR and FLC.
6.The analysis on 66 children with dead on arrival in emergency department
Chinese Pediatric Emergency Medicine 2013;20(1):66-68
Objective To investigate the causes and influencing factors of dead on arrival (DOA) in children.Methods The clinic data from 66 children with DOA admitted in the emergency department of Hunan Children's Hospital from Jan 2010 to Apr 2012 were analyzed retrospectively.Results All of the 66 cases had cardiac respiratory arrest when admission.Fourteen cases had arrest for 10 minutes,12 cases for 30 minutes to an hour,40 cases had no details.Forty-four (68.2%) cases were carried by parents,22(31.8%)cases were transferred by medical professionals.The main causes of DOA were severe pneumonia with respiratory failure and (or) heart failure,intracranial infection,neonatal diseases.All cases were taken to resuscitation room by triage immediately.Tracheal intubations were completed in 48 cases and intravenous access with injection of epinephrine and other resuscitative drugs were established in all cases,but all cases were dead due to breathing and heartbeat stopped for a long time.Conclusion DOA is one of the important reasons for pediatric high-risk.The key of reduction of DOA incidence and improvement of survival rate is to improve pediatric emergency medical service system,strengthen the health education for the parents,to carry out training and establish homogenization service in emergency ICU.
7.Clinicopathologic analysis of two cases of mucoepidermoid carcinoma of the skin
Chinese Journal of Dermatology 2014;47(12):896-898
Objective To describe the clinicopathologic features of two cases of mucoepidermoid carcinoma of the skin.Methods Two cases of mucoepidermoid carcinoma of the skin were analyzed histopathologically using hematoxylin and eosin (HE) staining,alcian blue-periodic acid Schiff (AB-PAS) staining and immunohistochemical staining.Relavant literature was reviewed.Results Histopathological examination showed that the tumor was subcutaneously located in both cases,with epidermoid cells and intermediate cells arranged in sheets or nests,as well as different sizes of glandular structures lined by mucinous columnar epithelium in some areas.Both tumors had a relatively clear boundary with peripheral invasive growth and no obvious capsules.Immunohistochemical examination showed positive staining for carcinoembryonic antigen (CEA),high and low molecular weight cytokeratin (CK(H) and CK(L)).The cytoplasm of mucous cells was stained blue with,and mucus was visualized after,AB-PAS staining.Conclusions Primary mucoepidermoid carcinoma of the skin is a kind of malignant tumor arising from skin appendages,whose diagnosis depends on histological and immunohistochemical examination.
8.Application of D2-40/S100 and CD34/S100 detection in the diagnosis of blood and lymphatic vessel invasion of cutaneous malignant melanoma
Chinese Journal of Dermatology 2015;48(4):266-269
Objective To develop an immunohistochemical assay for the diagnosis of cutaneous malignant melanoma (CMM) micrometastasis via blood and lymphatic vessels,and to evaluate its clinical significance.Methods Fifty-three patients (32 males and 21 females) histopathologically diagnosed as CMM were enrolled in this study.The patients were aged (61.2 ± 8.4) years (range,52-72 years).Tissue specimens were obtained from the central area of tumor in each case,and also from removed lymph nodes in some cases.The average duration of follow-up was (65.00 ± 5.68) months.During the follow-up,17 patients died of the recurrence or metastasis of CMM,and 6 patients were lost to follow-up.The expressions of D2-40,S100 and CD34 antigens in 53 tissue specimens were examined by immunohistochemical staining with three individual monoclonal antibodies,or by an immunohistochemical method using 2 two-antibody cocktails (D2-40/S 100 and CD34/S100) and double-color chromogens in single tissue sections.Results Of the 53 patients,30.19% (16/53) were positive for hematoxylin-eosin (HE) staining combined with immunohistochemical staining with individual monoclonal antibodies,and 49.06% (26/53) for the immunohistochemical method using two-antibody cocktails and double-color chromogens.Statistical differences were found in the positive rate between the two methods (x2 =3.94,P< 0.05).Compared with patients without blood/lymph vessel tumor emboli,those with blood/lymph vessel tumor emboli showed higher lymph node metastasis rate (80.77% (21/26) vs.37.04% (10/27),x2 =10.43,P < 0.001),but lower five-year survival rate (42.31% (11/26) vs.70.37% (19/27),x2 =4.25,P < 0.05).Conclusions The immunohistochemical method with two-antibody cocktails is superior to HE staining combined with immunohistochemical staining with individual monoclonal antibodies in the detection of blood/lymph vessel tumor emboli.And blood/lymph vessel tumor emboli may be an important prognostic factor in patients with CMM.
