Objective To raise the awareness of adrenal Castleman′s disease by analyzing the clinical features and management of a patient with adrenal Castleman′s disease. Methods A case of adrenal Castleman′s disease of our hospital was retrospectively analyzed, including clinical feature, laboratory findings, pathology, treatment, and follow-up. All the data and pertinent literatures were reviewed and analyzed. Results An incidentaloma measuring 4. 8 cm × 6. 3 cm in the right adrenal gland was observed in a 30-year-old men in a ultrasonography examination performed due to a medical check-up. Laboratory analysis showed that the lesion was not hyperfunctioning. The patient subsequently underwent an exploratory laparotomy. Pathological examination revealed retroperitoneally localized Castleman′s disease of the hyaline vascular type. Conclusion Adrenal Castleman′s disease is a rare cause of lymph node hypertrophy, and it is necessary to keep in mind the possibility of its occurrence and take it into consideration in the differential diagnosis of any solitary, heterogeneous, and hypervascular retroperitoneal mass. The proper cooperation between the clinician and pathologist allows early diagnosis and suitable therapy.

Objective To study the changes of serum level of high mobility group box-1(HMGB- 1)in patients with multiple trauma in order to forecast organ dysfunction(OD)and deaths.Methods The optical densities of HMGB-1 in serum of 35 patients with multiple trauma were determined on 1st,3rd, and 7th days after trauma,and the incidence of organ dysfunction and deaths were evaluated,then analyzed statistically to learn the relation between the serum levels of HMGB-1 and deaths with an attempt of predic- ting the incident of organ dysfunction and deaths.Results (1)As OD was concerned,there was a statis- tically significant difference in optical density of HMGB-1 on 1st and 3rd days between the two groups of multiple injury patients(t=4.411,P

20(Z= -2.117, P=0.034), and between the patients with OD and without OD (Z=-3.089, P=0.002), but PCT was not so between the non-surviror and survivor (Z=-1.307, P=0.191). The serum PCT level correlated with the incidence of organ dysfunction (x~2=14.82, P=0.033) and APACHEII (x~2=12.83, P

OBJECTIVETo explore the time law of electroacupuncture in regulation of circadian rhythms of the organism.

METHODSEffects of electroacupuncture at "Shenshu" (BL 23) at Zi, Wu, Mao and You periods on circadian rhythms of locomotor activity and core body temperature in hamsters were observed with chronobiological research methods.

RESULTSElectroacupuncture at Wu period could decrease the amplitude of locomotor activity rhythm (P < 0.05), at Mao period could delay the peak phase of circadian rhythm and at You period could advance the peak phase of circadian rhythm (both P < 0.05); and electroacupuncture at Mao period could delay 22.36 degrees and at You period advance 39.32 degrees for the rhythm peak of the circadian rhythm of core body temperature.

CONCLUSIONAcupuncture has a certain effect on circadian rhythm of locomotor activity and core body temperature.

OBJECTIVETo investigate the diagnostic value of histopathological changes in the liver of patients with neonatal intrahepatic cholestasis caused by citrin deficiency (NICCD).

METHODSLiver specimens from 10 cases of NICCD were evaluated by hematoxylin-eosin stain, histochemistry and immunohistochemistry (EnVision method). SLC25A13 mutation analysis was performed to correlate with histopathology.

RESULTSMost specimens showed varying degrees of fat deposition in hepatocytes, necrotic inflammation, cholestasis and fibrosis (so-called tetralogy). The combination of the above four histological changes was highly characteristic for NICCD. With the progression of the disease, hepatic fibrosis deteriorated and ultimately led to cirrhosis.

CONCLUSIONSNICCD should be suspected in the presence of cholestasis during infancy. A liver biopsy must be performed to rule out other liver diseases. The tetralogy of the hepatic histopathological changes has a highly diagnostic value for NICCD, which is also practical for accurately assessing the degree of inflammation and fibrosis, and similarly the progression of hepatic cirrhosis.

3 mg/L was significantly worse than in those with hs-CRP≤3 mg/L (18.18%,5.45%;P=0.044,log-rank test). Higher hs-CRP concentration was an independent predictor of death or new vascular event(OR 3.609;95% CI 0.869—14.992;P=0.047).Conclusion Higher hs-CRP concentration in acute phase after ischemic stroke is an independent predictor of death or new vascular event in a year.

This study was aimed to propagate and identify the prdm1 gene-knockout mice, so as to lay the foundation for studying Blimp-1 protein. Two kinds of transgenic homozygous mice with B6.prdm1(flox/flox) and B6.Lck-Cre were feed and propagated; after successful propagating, the first passage mice were obtained; after the first passage mice were copulated once again, the genotypes were obtained as follows: B6. prdm1(wild/wild). Lck-Cre, B6. prdm1(wild/wild), B6.prdm1(flox/flox). Lck-Cre, B6.prdm1(flox/wild). Lck-Cre, B6.prdm1(flox/flox), B6. prdm1(flox/wild). The genomic DNA of second passage mice was extracted, the Cre and loxp gene fragments were amplified by PCR, then the size of Cre and loxp genomic DNA were detected by agarose gel electrophoresis. The mice with B6.prdm1(flow/flox). Lek-Cre were used as conditionally prdm1-knockout mice, B6.prdm1(flox/wild). Lck-Cre mice, B6.prdm1(flox/flox) and B6 mice were used as controls. The spleen T lymphocytes and B lymphocytes were sorted by using magnetic beads, the blimp-1 target protein was identified by Western blot. The results showed that the two transgenic homozygous mice had the ability to reproduce, and the separation ratio of second passage mice generated from propagation of their offspring cach other meet Mendelian laws, and the prdm1 gene-knockout mice also could successfully obtained. It is concluded that the application of Cre-loxp system may successfully obtain plentiful prdm1 gene-knockout mice.

·AIM: To observe the therapeutic effect of visual perception training combined with total nutrition meal sequential therapy in the treatment of myopic amblyopia.·METHODS:Totally 73 children ( 135 eyes ) with myopic amblyopia were divided into control group ( 36 cases, 67 eyes) and treatment group (37 cases, 68 eyes) according to random number table. The control group were treated with traditional spectaculars and grating covering combined with fine eyesight training;the treatment group were treated with visual perception training combined with total nutrient meal sequential therapy. The visual acuity, diopter and average diopter of two groups were compared before and after treatment at 3, 6mo and 1a. The curative effect of two groups of children was compared after 1a treatment. And the adverse reactions were recorded in two groups during the treatment period. The recurrence rate of amblyopia in 1a follow-up was compared between two groups.·RESULTS: The difference of visual acuity between two groups was not significant at 3mo (P>0. 05). The visual acuity of the treatment group was significantly higher than that of the control group at 6mo and 1a (P<0. 05). There was no significant difference in diopter between the two groups after 3, 6mo and 1a (P>0. 05), but the average annual refractive changes in the treatment group were significantly lower than that in the control group ( P<0. 05). The basic cure rate and total effective rate of the treatment group were significantly higher than that of the control group (P<0. 05). There were no severe adverse reactions occurred between two groups during the treatment period. The recurrence rate of amblyopia in the treatment group was significantly lower than that in the control group (P<0. 05) after 1a follow-up.· CONCLUSION: Visual perception training combined with total nutrition meal sequential therapy in the treatment of myopic amblyopia in preschool children can significantly improve patients' visual acuity, reduce the average annual diopter changes, improve the therapeutic effect, reduce the recurrence rate of amblyopia.

The prenatal ethanol exposure induced the alterations of dendritic spine and synapse in visual cortex and their long-term effect would be investigated in mice from P0 to P30. Pregnant mice were intubated ethanol daily from E5 through the pup's birth to establish mode of prenatal alcohol abuse. The dendritic spines of pyramidal cells in visual cortex of pups were labeled with DiI diolistic assay, and the synaptic ultrastructure was observed under transmission electron microscope. Prenatal alcohol exposure was associated with a significant decrease in the number of dendritic spines of pyramidal neurons in the visual cortex and an increase in their mean length; ultrastructural changes were also observed, with decreased numbers of synaptic vesicles, narrowing of the synaptic cleft and thickening of the postsynaptic density compared to controls. Prenatal alcohol exposure is associated with long-term changes in dendritic spines and synaptic ultrastructure. The changes were dose-dependent with long term effect even at postnatal 30.
