Chinese Journal of Dermatology 2017;50(4):286-290
Objective To systematically analyze therapeutic effects of extracorporeal photopheresis (ECP) on refractory steroid-resistant,-dependent or-intolerant graft-versus-host disease (GVHD),to compare remission rates of skin GVHD in detail.Methods Databases were searched for studies concerning remission rates of GVHD after the treatment with ECP,and relevant data were extracted and pooled by using meta-analysis with STATA 12.0 software.Results A total of 22 literatures were reviewed,including 787 patients with refractory GVHD.Meta-analysis showed that the pooled complete remission (CR) rate and overall remission (OR) rate were 57% (95% CI:47%-66%) and 79% (71%-86%) respectively in patients with acute GVHD,27% (21%-33%) and 63% (58%-69%) respectively in patients with chronic GVHD,77% (71%-82%) and 87% (82%-91%) in patients with acute skin GVHD,as well as 39% (30%-48%) and 70% (63%-77%) in patients with chronic skin GVHD.Conclusion ECP is an effective therapy for refractory GVHD,especially for skin GVHD.

Objective To explore the effect of early screening and psychotherapy on post stroke depression. Methods 80 patients with stroke at first onset were assessed with Hamilton Rating Scale for Depression (HAMD-17). Patients with depression were divided into control group (n=21) and intervention group (n=21). Both groups received rehabilitation therapy and the intervention group received psychotherapy in addition. They were assessed with HAMD again 2 months after treatment. All of them were evaluated with modified Barthel index (MBI). Results 52.5% patients had post stroke depression. The score of HAMD-17 was lower in the intervention group than in the control group (P<0.01). There was no significant difference in MBI between 2 groups after treatment (P>0.05). Conclusion Early screening and psychotherapy can facilitate the recovery of patients with depression after stroke.

Objective To investigate the mycoplasma pneumoniae(MP) infection of the respiratory tract infection in children,the macrolide-resistant situation and resistance mechanism of MP. Methods The cultured throat swab specimens were obtained from 80 pediatric outpatients with respiratory tract infection from Dec.2008 to Mar.2009 in Beijing friendship hospital.The 23S rRNA gene of throat swab specimens and positive-cultured specimens were amplified using nested-PCR,and the products were further verified by electrophoresis and DNA sepuencing,which were collected from the outpatients.The specimens were divided into 2 groups depending on the findings of the gene sequencing whether they had gene mutation:sensitive and resistance group.The DNA sequence of samples were compared to the sequence of MP reference strain in genbank in order to findout MP drug resistant gene.The differences in macrolids therapy were investigated between 2 groups before the throat swab obtained.The drug resistance rates were compared between outpatients and inpatients. Results Thirty-two throat swab specimens were proved to be MP by direct nested-PCR,and 8 throat speeimens were proved to be MP by isolation and culrures.Total 33 cases(including 1 was positive-culture but nagative-direct PCR) were proved to be MP positive.Sixteen were identical to the M129 standard sequence,and 17 had point mutation in gene of 23S rRNA V region.Ten had A to G mutation at position 2063,3 had A to G mutation at position 2064,2 had A to G mutation at position 2067,1 had G to A mutation at position 2062,1 had A to T mutation at position 2063.There was no significant difference between the sensitive and resistance group in whether had macrolids before the throat swab obtained(P =0.909).And there was no significant difference in MP drug resistance rate between outpatients and inpatients(P =0.459). Conclusions The major mutation were A2063G and A2064G,and A2063T,A2067G,G2062A were newly found mutation points which were possibly related to macrolids resistance.

Ductular reaction (DR) is a phenomenon that refers to impaired hepatocellular proliferation and activated hepatic stem cells at times of demand such as hepatic regeneration.The components of ductular reactions are thought to be derived from activated hepatic progenitor cells,intermediate hepatobiliary cells,and reactive ductular cells.DRs are thought to play two roles in hepatocarcinogenesis:their hepatic progenitor cells may undergo malignant transformation and migration,and they may contribute to the development of the tumor's microenvironment.Exploring DR phenotype,cellular diversity,and relationship to hepatocarcinogenesis will further enhance our understanding of the pathogenesis of human hepatocellular carcinoma with an ultimate goal of developing new therapies.

Objective To explore the association of the inherent cellular level of reactive oxygen species (ROS) with the sensitivity of the gastric and esophageal carcinoma cells to arsenic trioxide (As 2O 3). Methods The difference of sensitivity to apoptosis induction by low concentration (2 ?mol/L) of As 2O 3 between the gastric carcinoma cell line SGC7901 and MKN45, and between the esophageal carcinoma cell line EC/CUHK1 and EC1867 was firstly demonstrated. SGC7901 was more sensitive than MKN45, and EC/CUHK1 more sensitive than EC1867 to As 2O 3. Then dihydrogenrhodamine 123 (DHR123), as a ROS capture, was incubated with the cells in the absence of As 2O 3. The fluorescent intensity of rhodamine 123, the product of cellular oxidation of DHR 123, was assayed by flow cytometry. The ROS levels was thus detected. Results Inherent cellular ROS level is higher in SGC7901 and EC/CUHK1. They are more sensitive to As 2O 3, than the corresponding cell line MKN45 and EC1867. Conclusions The difference in inherent cellular ROS level of gastric and esophageal carcinoma cells is associated with the cellular sensitivity to apoptosis induced by As2O 3.

Objective To study the protective effects of rosiglitazone against early skin changes in experimental diabetic rats. Methods Diabetic models were established in male Wistar rats aged 8 to 10 weeks by using streptozotocin (STZ). Then, 39 experimental diabetic rats were equally divided into insulin-treated diabetic group (DI group), rosiglitazone-treated diabetic group (DR group), diabetic control group (DC group),and 13 normal rats served as the control (C group). The rats were given subcutaneous insulin (1 - 2 U) twice daily in DI group, intragastric rosiglitazone (5 mg/kg) once daily in DR group, and intragastric sterile water in DC and C groups. Sixteen weeks later, heart blood samples were collected from all the rats for the measurement of tumor necrosis factor (TNF)-α, interleukin (IL)-6, C reactive protein (CRP), superoxide dismutase (SOD) and P substance (SP) levels, then the rats were killed and tissue samples were obtained from the medial area of the dorsal skin and subjected to pathological observation, measurements of skin as well as dermal thickness, and immunohistochemical examinations for the expression of advanced glycation end products(AGEs) and peroxisome proliferator activated receptor-γ (PPAR-γ). Results The levels of IL-6, TNF-α and CRP in the DC group were significantly higher than those in the C group (135.05 ± 43.39 ng/L vs. 99.92 ±32.36 ng/L, 1.45 ± 0.67 μg/L vs. 0.86 ± 0.60 pg/L, 3.51 ± 0.62 mg/L vs. 2.54 ± 1.31 mg/L, all P < 0.05),while no significant difference was found between C group and DI group or DR group (all P> 0.05). Decreased levels of SOD and SP were noted in the DC group (70.71 ± 37.52 U/ml, 22.22 ± 7.93 ng/L), compared withthe C group (137.76 ± 27.6 U/mL, 29.57 ± 3.74 ng/L, both P< 0.01), DI group (149.96 ± 13.25 U/mL, P<0.01; 29.79 ± 5.21 ng/L, P< 0.05) and DR group (128.50 ± 38.27 U/mL, P< 0.01; 33.35 ± 15.0 ng/L, P<0.05 ). Micrometer measurements indicated that the skin thickness was significantly lower in the DC group than in the C group, DI group and DR group (0.77 ± 0.18 mm vs. 1.59 ± 0.26 mm, 1.47 ± 0.50 mm and 1.22 ±0.47 mm, P < 0.01, 0.01, 0.05 respectively). Histological observation found a mild disarrangement of epidermal cells, shrinkage, swelling and degeneration of dermal collagen as well as progressive atrophy or disappearance of subcutaneous fat in the DC group. No obvious histological changes appeared in the DI or DR group. Immunohistochemistry indicated that AGEs and PPAR-γ proteins, which were stained into brown granules, were located in the vascular basement membrane, stromal cells, etc, of skin. The DC group showed the highest expression of AGEs but lowest expression of PPAR-γ. Conclusions There is an accumulation of AGEs and elevated expressions of inflammatory factors in the skin of experimental diabetic rats, and rosigLItazone shows a protective effect against the early skin changes.
