Objective To investigate the reflectance confocal microscopy (RCM) features of mycosis fungoides (MF).Methods Four male and two female patients with MF,who were aged 7-73 years with a clinical course of 1-5 years,were collected from June 2011 to May 2012 in the department of dermatology.Of the six patients,two were in patch stage,three in plaque stage,and one in tumor stage.All the cases were confirmed by histopathological,immunohistochemical and relevant examinations.For each patient,three lesions were selected and investigated using RCM,and one of the three lesions was subjected to histopathological examination.Results RCM features of MF included hyperkeratosis,disarray of honeycomb of stratum spinosum,reduced refractivity of dermal papillary rings,roundish or round scattered hyperrefractive cells in the epidermis,infiltration of a small quantity of inflammatory cells in the papillary dermis.Occasionally,some round to oval hyporefractive cells aggregated to form vesicle-like structures.These RCM features correlated well with histopathologic findings.Conclusion Combined with clinical manifestations,RCM may serve as a noninvasive auxiliary tool for the diagnosis of MF.

OBJECTIVETo understand the distributions of waist circumference and waist-to-height ratio (WHtR) in Han and Uygur ethnic children aged 3-9 years in Xinjiang Uygur Autonomous Region (Xinjiang) and discuss their values in obesity screening in children.

METHODSStratified cluster random sampling was conducted to select Han and Uygur ethnic children from kindergartens and primary schools in four areas of Xinjiang in April 2014. The children's standing height, body weight and waist circumference were measured by trained investigators according to standard protocol. WC>or=P80 and WHtR>or=0.48 were used as the cutoff value for abdominal obesity screening in children with normal BMI. The association between overweight/obese prevalence rate and obesity related indicators, such as BMI, WC, WHtR, were analyzed.

RESULTSA total of 4024 Han and Uygur ethnic children were investigated, in which 2461 were in Han ethnic group, 1563 were in Uygur ethnic group. The WC and WHtR at P50 and P80 were differed significantly. In both Han and Uygur ethnic groups, there were some children with WC>or=P80 or WHtR>or=0.48, although they had normal BMI. This proportion decreased with age.

CONCLUSIONSThe WC and WHtR are similar in Han and Uygur ethnic children aged 3-9 years. WC and WHtR have values in obesity screening for children with normal BMI which suggested to use it as the supplementation of BMI in obesity screening in preschool aged children.

OBJECTIVETo investigate the expression of Caspase-3 and Hsp70 in rabbits after severe traumatic brain injury (TBI) and to explore the feasibility of its application in estimation of injury time in forensic medicine.

METHODSA rabbit model of heavy TBI was developed by high velocity impact on the parietal bone with an iron stick. Totally 8 healthy adult New Zealand white rabbits were randomly divided into control group (n equal to 2) and injury group (n equal to 6). Four hours after injury, tissue specimens from the parietal lobe, temporal lobe, occipital lobe, cerebellum and brainstem were harvested to detect the expression of Hsp70 and Caspase-3 by immunohistochemistry. Besides, the gray values of cells positive for Hsp70 and Caspase-3 were analyzed with an image analyzer.

RESULTSImmunohistochemistry staining demonstrated a low level of Caspase-3 and Hsp70 expression in normal control group. While in injury group, both the Caspase-3 and Hsp70 expression was significantly elevated (P less than 0.05). Positive cells gathered around the lesion focus. Occipital lobe and cerebellum had fewer positive cells while temporal and brainstem had the fewest.

CONCLUSIONThe expression of Caspase-3 and Hsp70 at an early stage following severe TBI is characteristic and can be applied to estimate the time of injury.

BACKGROUND:The pathogenesis of knee intraarticular adhesion is yet unknown. Excessive proliferation of fibroblasts is considered to cause knee intraarticular adhesion. OBJECTIVE:To study the preventive effects of methotrexate on knee intraarticular adhesion through fibroblast apoptosis induced by endoplasmic reticulum stress. METHODS:The viability of the cultured fibroblasts treated with methotrexate(10-5-10-9mol/L)or PBSwas determined after 24 hours. Fibroblast apoptosis was detected by Hoechst33342 staining. Endoplasmic reticulum stress-and apoptosis-related proteins, including cleaved-PARP, CHOP, Bax and Bcl-2, were determined by western blotassay. Eighteen healthy male New Zealand white rabbits were used to establish the knee intraarticular adhesion models, and equaly randomized into three groups, and received topical application of 2 or 1 g/L methotrexate, or normal saline (control). The preventive effects of methotrexate on knee intraarticular adhesion and CHOP expression in scar tissue were observed. RESULTS AND CONCLUSION:Methotrexate inhibited the proliferation and viability of fibroblasts in a dose-dependent manner. The number of apoptotic fibroblasts was significantly increased compared with control group. Protein expression of cleaved-PARP, CHOP, and bax was increased, while protein expression of bcl-2 was decreased with time. The animal experiment showed that preventive effects of 2 g/L methotrexate on knee intraarticular adhesion were superior to 1 g/L methotrexate treatment. CHOP expression in the scar tissue in the methotrexate groups was higher than the control group and that was higher in high-dose methotrexate group. Our results suggest that methotrexate prevents knee intraarticular adhesionviaendoplasmic reticulum stress-induced fibroblast apoptosis.

OBJECTIVE: To investigate the significance of tumor necrosis factor-alpha (TNF-α) and plasma endothelium (ET) in pathophysiologic process of patients with obstructive sleep apnea hypopnea syndrome(OSAHS) with type 2 diabetes mellitus (T2DM). METHOD: All observed subjects were divided into 4 groups. A number of 80 patients with OSAHS, 65 cases of OSAHS with T2DM patients, 20 patients with T2DM, and 32 cases of healthy control group were observed in this study. The serum levels of TNF-α and ET were detected by double antibody sandwich ELISA, the content of TNF-α and ET were compared between OSAHS group and OSAHS + T2DM group. It were also compared before and after treatment of CPAP or surgery. RESULT: TNF-α level is higher in OSAHS+T2DM group than that in the OSAHS group, T2DM group and the control group (P < 0.05); TNF-α level in OSAHS group and the T2DM group are higher than that in the control group (P < 0.05), but there was no difference in TNF-α level between the OSAHS group and the T2DM group. There was also no difference in ET level of the four groups. There were significant differences of TNF-α before and after treatment of CPAP or surgery in OSAHS group and OSAHS+T2DM group (P < 0.05). But there was no significant differences of ET before and after treatment of CPAP or surgery in the OSAHS+T2DM group (P > 0.05). CONCLUSION TNF-α may be involved in the development of OSAHS and T2DM, while ET may have little effect on the occurrence and development of OSAHS and T2DM.

Objective To investigate the effects of simultaneous multi-level surgery for moderate to severe obstructive sleep apnea hypopnea syndrome (OSAHS). Methods A retrospective analysis was made on surgical cases of one hundred and thirty seven patients with moderate to severe OSAHS diagnosed by polysomnography (PSG). They were divided into multi-level group (n = 95) and UPPP group (n = 42). The two groups were compared in terms of postoperative complications as well as the related indicators of PSG , calgary sleep apnea quality of life index (SAQLI), epworth sleepiness scale (ESS), snore scales (SS) before operation and after operation. Results Just one patient in the multi-level group had difficulties in respiration and was rescued by timely tracheotomy. The AHI, LSaO2, TS90%, the total score and the scores on the four dimensions of SAQLI, ESS score, SS score in the multi-level group were significantly improved as compared both to the results after operation (P < 0.01) and to the UPPP group (P < 0.05). But only the AHI, LSaO2 and TS90% in the UPPP group were improved (P < 0.05). Conclusions The multi-level surgery is a safe and feasible therapy or moderate to severe OSAHS. The evaluation in subjective and objective ways can be more accurate in comprehensive reflecting the surgical efficacy and effects of OSAHS on patients′ of life quality.

Objective To detect time-dependent change of neuritin expression in brain tissues after traumatic brain injury and discuss the effect of neuritin after brain damage occurred. Methods Forty-two rats were divided into normal group, control and experimental group. According to the postoperative time divided into 6 subgroups, including 6 hours group, 12 hours group, 24 hours group, 3 days group, 7 days group and 14 days group. Immunohistochemical and western-blot were used to detected the protein expression levels of neuritin. Results The immunohistochemical staining indicated that the positive expression of neuritin was strong in the cytomembrane and cytoplasms of the neurons, with a higher intensity, 6 hours after the operation. 12 hours after the operation last to the seventh day, the neurons with the strongest positive expression, is significantly higher than control group and normal group, significant decrease on the fourteenth day. The result of western-blot indicated that the level of neuritin protein sharply increased at 6 hours, reached the peak on 24 hours and after lasted to the seventh day, significantly higher than control group and normal group (P < 0.01), significant decrease on the fourteenth day (P < 0.05). Conclusion Up-regulation of neuritin in cerebral contusion tissues may play an important role after traumatic brain injury.
