A 2-month-old baby girl developed universal keratotic plaques soon after birth. Physical examination revealed well-defined, dark erythematous, keratotic plaques with thick scales and mild infiltration at the periorbital, perioral, perianal and vulvar regions, as well as deep fissures of both hands and feet covered with thick yellowish crusts. Another case was a 24-year-old female, the mother of the baby, who presented with hyperkeratotic plaques at perioral and perianal regions, congenital alopecia universalis, mutilation of fingers and toes with massive thick keratotic yellow crusts and scales. Histopathology of skin lesions from the gluteal region of the baby showed psoriasiform hyperplasia of the epidermis, slight inflammatory infiltration of dermal papillae and superficial dermal perivascular regions. Immunohistochemistry demonstrated the positive staining for acidic keratin (AE1) in the prickle cell layer and granular layer and for CK10 in the upper prickle cell layer and granular layer. Electron microscopy showed increased cell space and decreased tonofilament. Both the baby girl and her mother were diagnosed with Olmsted syndrome.

AIM: To dynamically observe the feeling change of the photorecrptor layer in the eyes with acute central serous chorioretinopathy ( CSCR ) krypton laser treatment by fourier - domain optical coherence tomography ( FD - OCT), and to study their correlation with the chang of vision.
METHODS: This is a retrospective case series study. The clinical diagnosis of 52 patients with monocular initial onset of central serous chorioretinopathy, krypton laser photocoagulation before treatment, after 1, 2, 4, 6, 8wk, 6mo, FD - OCT were performed to observe the morphological changes characteristic of photoreceptor layer and changes in vision.
RESULTS: After 1wk treatment, all cases were improved; 2wk, 6 cases were cured; 4wk, 38 cases were cured; 6wk, 41 cases were cured; 8wk, 45 cases were cured, the OCT showed macular retinal neuroepithelial layer ( RNL ) from fully absorbed; 6mo with the same 8wk. Before and after treatment in patients with best corrected visual acuity and from the height difference between the macular region of RNL was statistically significant (P<0. 05), there was a correlation between the changes of visual acuity after treatment and the macular detachment of RNL height (P<0. 05), Photoreceptor layer of complete and incomplete best corrected visual acuity difference was statistically significant (P<0. 01).
CONCLUSION: FD-OCT can dynamicaly observed acute central serous chorioretinopathy krypton laser treatment of photoreceptor ultrastruture changes. Photoreceptor layer of complete and incomplete best corrected visual acuity difference was statistically significant (P<0. 01).

Objective To investigate the correlations of serum adipocyte fatty acid-binding protein (AFABP),adiponectin (APN) and A-FABP/APN ratio with acute ischemic stroke (AIS) and its subtypes.Methods The consecutive patients with AIS (AIS group) of having complete data admitted within 24 hours of onset were enrolled,and at the same time,the healthy subjects of age,sex and body mass index matched with the AIS group were selected as a control group.The demographic characteristics and general clinical data of the AIS group and control group were collected.The serum A-FABP and APN levels were detected by enzymelinked immunosorbent assay.The patients in the AIS group were further divided into large artery atherosclerosis (LAA),small artery occlusion,(SAO),cardioembolism (CE),and stroke of other determined etiology (SOE) according to the TOAST classification criteria.Multivariable logistic regression analysis was used to investigate the relationship between all factors and AIS and its subtypes.Spearman correlation analysis was used to analyze the correlations of the A-FABP and APN levels and the NIHSS scores.Results The serum A-FABP level (P =0.017) and A-FABP/APN ratio (P =0.002) in the AIS group were significantly higher than those in the control group,and the serum APN level was significantly lower than that in the control group (P =0.011).Multivariate logistic regression analysis showed that the increased serum A-FABP level (odds ratio [OR] 1.48,95％ confidence interval [CI] 1.07-1.93; P =0.009) and the A-FABP/APN ratio (OR 1.59,95％ CI 1.10-2.34; P =0.002) as well as the decreased APN level (OR 0.36,95％ CI 0.14-0.65; P =0.011) were independently associated with AIS.And the A-FABP/APN ratio was better than the correlation of both separately.The serum A-FABP level and A-FABP/APN ratio in the LAA,SAO and CE groups were significantly higher than those in other subtype groups (all P ＜0.05),and the APN level was significantly lower than that in other subtype groups (P ＜0.05).Multivariate logistic regression analysis showed that the increased serum A-FABP level and A-FABP/APN ratio as well as the decreased APN level were independently associated with LAA,SAO and CE,and the A-FABP/APN ratio was better than the correlation of both separately.The baseline NIHSS score was positively correlated with the serum A-FABP level (r =0.236,P =0.019),it was negatively correlated with the serum APN level (r =0.307,P =0.002),and the correlation of the serum AFABP/APN ratio was higher than that of A-FABP or APN (r =0.326,P =0.001).Conclusions The increased serum A-FABP level and the decreased APN level may serve as the new risk factors for AIS,especially LAA,SAO and CE subtypes,and they can reflect the severity of AIS.

Objective To explore the effects of granulocyte colony stimulating factor (G-CSF)on chronic cerebral ischemia in rats,and its possible mechanism.Methods Chronic cerebral ischemia (2-VO) model was prepared and bilateral external jugular veins were isolated.A total of 30 rats were divided into 2 groups at random sham group (received no intervention,n=15) and operative group (received G-CSF or PBS through external jugular vein injection,n=15).At 6 weeks after operation,the rats in operative group were divided into G--CSF group (received G-CSF 10 mg/L,1 ml · kg-1 · d-1,1 times every 24 h for,3 times) and PBS control group (received PBS 10 mg/L,1 ml ·kg 1 · d-11,1 times every 24 h for 3 times).At 8 weeks after the operation,morris water maze was carried out to evaluate the learning and memory ability of the rats.The cell proliferation,threedimensional vascular distribution,ischemic neuronal apoptosis,cell morphological changes in ischemic area and the plasma VEGF levels were detected to explore the possible mechanisms.Results In morris water maze,escape latency at the 2rd to 5th day were significantly lower in G-CSF group than the PBS group (all P＜0.05).The swimming time spent in the first quadrant in G-CSF group was significantly longer than the PBS group (P＜0.05).There was a significant difference in the number of BrdU positive cells in the ischemical area between the G-CSF group and the control group [(27.7±4.76) vs.(10.4 ± 3.7),P =0.030).Three-dimensional quantitative measurements of vascular structure showed that the capillary diameters was smaller in the G-CSF group than in the PBS group [(2.90±0.20) μm vs.(3.45±0.26) μm,P=0.020] and the number of branch points in the boundary regions of ischemia had a significant difference in the G-CSF group compared with the control group [(207.82±10.73) /0.002 mm3 vs.(162.10±9.31) /0.002mm3,P=0.005].Threedimensional cerebral vessel surface area in the ipsilateral hemisphere was increased in the G-CSF group compared with the PBS group [(86498±2896) μm2/0.002 mm3vs.(73976±3826) μm2/0.002 mm3,P=0.003].The number of apoptotic cells in G-CSF group was decreased compared with the PBS group [(32.10±6.70) vs.(56.30±11.20),F=11.89,P=0.043].The electron microscope morphological observations showed inflammatory edema in intercellular gap was significantly reduced in the G-CSF group compared with the PBS group.The level of plasma VEGF was significantly increased in the G-CSF group compared with the PBS group [(58.81±6.61) ng/L vs.(20.81±4.35)ng/L,P=0.025].Conclusions G--CSF can improve the learning and memory ability in the chronic cerebral ischemic rats,and its possible mechanism might involve the nerve protection and the vascular regeneration associated with the VEGF.There is a great prospect for G-CSF in the therapy of chronic cerebral ischemic disease.

A 73-year-old man developed a skin-colored granule-sized papule on the scrotum 10 years prior to the presentation,which had increased in size and number without obvious symptoms.Histopathological examination showed multiple enlarged intradermal cysts.The cyst wall consisted of one or two layers of flat or columnar cells.Decapitation secretion was seen in the inner layer cells,and the out layer of cysts was formed by flat or cubic myoepithelial cells.A diagnosis of apocrine hidrocystoma of the scrotum is made.

According the current National standard for laboratory animal, herpes B virus antibody must be tested and negative for all the breed/tested macaques,howere,in fact the positive rate is around 60-70% in breeding colony. Being the National Standard, if it is too far from the reality of the filed, weighing and changing should be made.Hardness/crispness degree of laboratory animal diet never been considered as a listed value in the National Standard for Laboratory Animal to identify the quality of diet.In fact, this index affects a lot about daily diet intake and physiological status of laboratory animals.Hereby, the authors suggest to take the index into the National Standard, to assess the quality of laboratory animal diet in a more comprehensive way.

Objective To summerize the experiences of using random flaps to reconstruct soft tissue defects of the periorbital region.Methods Periorbital soft tissue defects in 65 patients underwent reconstruction surgery by random flaps with pedicle 1.0～2.5 cm in width.The length of the flap ranged from 1.0 cm to 3.5 cm,with the rate of length to width less than 2.5:1.Detail plans on flap and incision design were made based on the aesthetic and functional problems.Results Phenomena of blister and purplish red in the edge or the distal area of the flaps were observed in 3 cases,and were disappeared after corresponding treatment.The other flaps survived and the wound healed primarily after operation.The color and the texture of the flaps matched well to the adjacent tissues with satisfied function and aesthetic Results .Conclusion Random flap is an ideal substitute to repair periorbital soft tissue defects.

Objective: This study is the first to adopt a cultural and contextual coping model to examine the impact of forbearance coping on compliance and psychological health and unravel the psychosocial mediator and moderator among community-dwelling residents in the post-pandemic era in China. Methods: A multistage cluster convenience sampling strategy was conducted to recruit 402 community-dwelling residents of ten cities in Guangdong province who completed an online survey measuring forbearance coping, anti-pandemic compliance behaviours, family resilience, community resilience and psychological distress. Results: The study results showed an unexpected negative influence of forbearance coping on psychological distress. Nevertheless, forbearance coping facilitated personal compliance with coronavirus disease-2019 mitigation measures and improved psychological health. More importantly, meaning-making of adversity within families partially mediated the negative effect of forbearance on mental health only when respondents perceived higher levels of community resilience. Conclusion This study is the first to apply the cultural and contextual model of coping to Chinese individuals during a significant public health crisis. It expands the model by uncovering mechanisms like behavioural compliance and family meaning-making, and highlights the moderating role of community resilience. The findings emphasize the importance of building resilient communities and supporting mental health, providing evidence for future policy interventions and pandemic/disaster prevention measures in China.
