Objective To investigate the diagnostic value of Lugol solution staining combined with nar-row band imaging (NBI)for esophageal cancer and precancerous lesions.Methods From December 201 3 to December 2014,1 87 patients who were with suspicious esophageal lesions and stained with Lugol solution under endoscopy were selected as control group,while from January 2015 to June 2015,124 patients who were with sus-picious esophageal lesions and examined with Lugol solution staining and NBI under endoscopy were selected as observation group.The sensitivity,specificity and accuracy between the two groups were compared and analyzed. Results One hundred and four cases (75.0%)were found among observation group,which was higher than 93 cases (55.6%)among control group (χ2 =12.07,P <0.01 ).The total detection rates of esophageal cancer and high grade intraepithelial neoplasia (HGN)were 29.0% and 17.7% in observation group respectively,which were higher than 1 8.2% and 6.4% in control group (χ2 =4.15,P =0.04;χ2 =8.54,P <0.01 ).The Kappa value in observation group was 0.55,which was higher than 0.36 in control group.The sensitivity and accuracy in observation group were 89.9% and 82.3% respectively,which were significantly higher than 71 .8% and 68.4% in control group (χ2 =9.79,P <0.01 ;χ2 =7.38,P <0.01 ).Conclusion The sensitivity and accuracy of endoscopic Lugol solution staining combined with NBI for esophageal cancer and precancerous lesions are higher than Lugol solution staining,and it is worthy to popularize the application of Lugol solution staining com-bined with NBI in diagnosing esophageal cancer and precancerous lesions.

BACKGROUND:The chronic wounds, also cal ed non-heading wounds, can seriously affect the quality of life of patients and has brought heavy burden to patients, as wel as health care professionals. celltherapy is a new method for promoting wound healing and plays an important role in the repair of chronic wounds.
OBJECTIVE:To summarize the progress of researches on the chronic wound healing mechanism and celltherapy, and to provide evidences for the clinical management of chronic wounds and relative basic researches.
METHODS:A computer search of CNKI database from 2005 to 2012, PubMed database from 1995 to 2012 and Foreign Medical Journal Ful-Text Service database from 2000 to 2012 was performed using“non-healing wounds, diabetic foot ulcer, wound healing, celltherapy”in Chinese and English as the key words to retrieve articles about chronic wound healing mechanism and the application of celltherapy. Total y, 42 articles meeting the inclusive criteria were included in result analysis.
RESULTS AND CONCLUSION:The wound healing is a complex biological process, involving multiple celltypes, extracellular matrix and cytokine factors. The delayed healing of refractory wound seriously affects the quality of life of patients and has brought heavy economic burden to patients. At present, many methods have been employed to promote wound repair, such as local hyperbaric oxygen therapy, surgical treatment, herbal Chinese medicine, application of various growth factors, celltherapy and gene therapy. celltherapy is noninvasive and those delivered cells can adapt to their environment, are able to release growth factors and cytokines, and more importantly, are able to deliver the growth factors for the wound healing process due to cellsignaling capabilities. Currently, cells used for the treatment of chronic wound cells mainly include bone marrow stem cells, bone marrow-derived mesenchymal stem cells, cord blood stem cells, peripheral blood stem cells, epidermal stem cells, skin-derived progenitor cells, adipose stem cells, fibroblasts and platelets.

Objective To study the changes of corneal sensitivity in diabetic and nondiabetic subjects after phacoemulsification. Methods This trial involved 42 diabetic subjects(42eyes)and 46 nondiabetic subjects(46 eyes)with cataract.All eyes were underwent phacoemulsification.Corneal sensitivities were tested before surgery and 1 day,1 week,1 month,3 month,6 month after surgery.Results The corneal sensitivity of diabetic subjects was greatly reduced at 1 day,1 week,1 month,3 month after surgery(P＜0.05),and returned to the preoperative values at 6 month(P＞0.05).The corneal sensitivity of nondiabetic subjects was reduced at 1 day,1 week,1 month af- ter surgery(P＜0.05),and returned to the preoperative values at 3 month(P＞0.05).The corneal sensitivity of diabetic subjects was lower than nondiabetic subjects before surgery(P＜0.05).The reduced range of corneal sensitivity in diabetic subjects was greater than that of nondiabetic subjects(P＜0.05).Conclusions The corneal sensitivity is decreased and the recovery is postponed after poacoemul- sification in diabetic subjects.

Brain injury is one of the most serious diseases in neonatal period,which can cause cerebral palsy,motor development delay,cognitive dysfunction and learning difficulties and other sequelae,and severely affects the health development and quality of life of the newborn.Neonatal brain injury (NBI) is a wide range of diseases caused by a variety of causes,its clinical manifestations lack specificity,clinically,it is difficult to judge the severity,duration and the time of prenatal injury,and it has been paid much attention to by scientific researchers and clinicians.At present,imaging method is a major means of NBI diagnosis,but imaging examination is usually a lag and limitations.Levels of humoral biomarkers change early after brain injury,and early brain injury can be predicted by detecting their changes.In recent years,a variety of sensitive brain damage biomarkers have been detected in various body fluids of newborns,mainly including neuron-specific enolase (NSE),ubiquitin carboxyl hydrolase L1 (UCH L1),S100B protein,tau protein,myelin basic protein (MBP),glial fibrillary acidic protein (GFAP) and activin A and so on.the application and research progress of these commonly used biomarkers in NBI are reviewed in this paper.

Objective:To investigate the effect of a low calcium diet on the distal and proximal tibial metaphysis in male rats using bone histomorphometrical techniques. Methods:Forty 3-month-old male Sprague-Dawley(SD) rats, with a mean weight of 280?22g, were randomized into five groups. Group one and group two were fed a normal diet (Ca 1.0%) and a very low calcium diet (VLCD ,Ca 0.1%) respectively for one month,and the rest three groups were fed a normal diet (Ca 1.0%), a very low calcium diet (VLCD, Ca 0.1%) and a low calcium diet (LCD , Ca 0.3%) respectively for three months. All animals received double bone fluorochrome labeling prior to sacrifice. At the end of experiment, the left tibiae were harvested for bone histomorphometrical evaluations. Results:After one month, compared to control group, distal tibial metaphysis(DTM) of VLCD did not change significantly but proximal tibial metaphysis(PTM) was decreased significantly whose percent trabecular area (%Tb.Ar) was decreased to 38% (P

Objective:To observe the clinical efficacy of combining tuina and Chinese herbal fumigation for chronic ankle sprain.
Methods:A total of 93 cases were randomly allocated into an observation group (n=47) and a control group (n=46) according to the table of random number. Cases in the observation group received tuina combining with Chinese herbal fumigation, whereas cases in the control group received oral blood-circulating and pain-alleviating capsules combining with Chinese herbal fumigation. Both tuina and Chinese herbal fumigation were done once every other day and 10 times made up a course of treatment. The Baird-Jackson ankle scoring system and clinical efficacy were observed after 1 course of treatment.
Results:After treatment, except for radiographic findings, there were significant intra-group differences in individual item scores of Baird-Jackson (P<0.05,P<0.01); except for ankle joint range of motion (ROM), there were significant between- group differences in individual item scores and total score (P<0.01). The excellence and good rate was 76.6% in the observation group, versus 54.4% in the control group, showing a statistical significance (P<0.05).
Conclusion:Combining Chinese herbal fumigation and tuina based on the muscle region theory can obtain better effect than combining oral blood-circulating and pain-alleviating capsules and Chinese herbal fumigation for chronic ankle sprain.
