Objective To investigate the CT findings of orbital inflammatory pseudotumor in different types and to improve the diagnosis and differential diagnosis of this disease.Methods CT findings of orbital inflammatory pseudotumor in 58 cases confirmed by clinic or pathology were analysed retrospectively.Results This disease could be categorized five types according to CT findings: ①mass type in 5 cases (8.6%), the characteristic CT findings were soft-tissue masses in intraorbit; ②diffusion type in 5 cases (8.6%) showed retrobulbar fat interspace of high-density without masses; ③myositis type in 22 cases(37.9%) showed the enlargement of entire muscles including the tendinous insertion;④lacrimal galnd type in 6 cases(10.3%) showed enlargement of lacrimal gland on CT; ⑤the mixed type in 20 cases (34.5%) showed hypertrophy of the extra-ocular muscles adjacent to mass and high-density of surrounding fat ,or hypertrophy of the extra-ocular muscles adjacent to enlarged lacrimal gland.There were in different degree of paranasal sinusitis such as maxillary sinusitis and/or ethmoid sinusitis in 22 cases(37.9%).Conclusion CT scan is of important role in diagnosing and differential diagnosing orbital inflammatory pseudotumor.

Objective To statistically analyze the 128 cases of thumb abductor defects and evaluate the commonly used operative methods. Methods Statistical analysis and evaluation were done in regard to the muscle strength, injury cause, injured parts, injured nerves and tendon transfer. Results We found by following up after the operation: FDS, PL, ECU were the most commonly used operative methods and their average excellent and good rate was 87.2%. Abductor digiti quinti and flexor pollicis brevis were less used but their effects were good. Conclusion When the median nerve of thenar is injured, the abductor of the thumb will be damaged. We should restore its function by tendon transfer as long as the muscle strength remains and the passive motion of the carpometacarpal joint is good.

Objective To estimate the influence of curcumin on psoriasis-like lesions and proliferating cell nuclear antigen (PCNA) expression in guinea pigs,so as to investigate the therapeutic effect and mechanism of curcumin in psoriasis.Methods A model of psoriasis-like skin inflammation was established by applying propranolol 5％ cream (4 times a day for 3 weeks) to the dorsal skin of ears of 30 guinea pigs,which were then equally classified into 5 groups:model group receiving no treatment,observation group receiving no treatment but observation for 2 weeks,model control group treated with intragastric 25％ polyethylene glycol solution (1 rnl once a day) for 2 weeks,low-dose and high-dose curcumin groups treated with intragastric curcumin solution at 20 and 40 mg/kg per day respectively once a day for 2 weeks.Six guinea pigs receiving neither induction by propranolol nor treatment by curcumin or polyethylene glycol solution served as the normal control group.Skin specimens were harvested from the ears of guinea pigs in the normal control group after three weeks of breeding,in the model group immediately after the establishment of psoriasis-like model,in the observation group after 2 weeks of observation,and in the other 3 groups after 2 weeks of treatment.Subsequently,haematoxylin-eosin (HE) staining was conducted to observe histopathologic changes,and immunohistochemical assay to detect the expression of proliferating cell nuclear antigen (PCNA).Results Gross observation of the skin revealed that curcumin attenuated psoriasis-like skin manifestations in guinea pigs.There were significant differences in histopathologic scores (F=296.14,P＜ 0.01) and PCNA expression rate among the 6 groups (F =108.49,P ＜ 0.01).Least significant difference (LSD) test showed that both histopathologic scores and PCNA expression rate were significantly higher in the model group than in the normal control group (6.42 ± 0.49 vs.0.92 ± 0.20,63.17％ ± 5.47％ vs.20.83％ ± 2.99％,both P ＜ 0.01).After 2 weeks of treatment,both low-dose and high-dose curcumin groups showed significantly lower histopathologic scores (4.25 ± 0.27 and 1.75 ± 0.42 vs.6.42 ± 0.49,both P＜ 0.01) and PCNA expression rate (43.50％ ± 2.90％ and 25.50％ ± 3.74％ vs.63.17％ ± 5.47％,both P ＜ 0.01) compared with the model group.Conclusion Curcumin can attenuate pathological manifestations of psoriasis-like lesions,and downregulate PCNA expression in guinea pigs.

Objective To investigate the effect of Dexamethasone on microtubule - associated protein 1 light chain 3(LC3)expression of cells and neurons in cerebral cortex of juvenile Wistar rats with sepsis. Methods Models of juvenile Wistar rats with sepsis were established through cecal ligation and puncture(CLP). Totally 60 cases of 30 -day - old juvenile male Wistar rats were randomly divided into sham - operation group(10 cases),non - treated group (25 cases)and Dexamethasone group(25 cases). Twelve hours after CLP,rats in Dexamethasone group were injected with Dexamethasone(1 mg / kg)via tail vein every other day,with a total of 3 times. The same dose of saline was used in the non - treated group. All rats were killed at the age of 40 days. Expressions of LC3 and neuronal nuclei(NeuN)of cells in cerebral cortex of rats were detected by using immunofluorescence assay,and the number of positive cells was calculated by using image analysis system software. Expressions of LC3 - Ⅰ and LC3 - Ⅱ protein were measured by a-dopting Western blot. Results Three hours after CLP,rats appeared to be curled up and showed piloerection and shi-vering and the neurobehavioral score in non - treated group was significantly lower than that in sham - operation group (t = 9. 895,P = 0. 000). Twelve of 25 rats in Dexamethasone group died in 10 days after CLP(48% ),while 8 of 25 rats in non - treated group died(32% ),and the difference was not statistically significant between the 2 groups(χ2 =1. 333,P = 0. 248). The immunofluorescence staining and image analysis showed the percentage of LC3 positive cells in non - treated group was significantly increased(0. 606 7 ± 0. 030 1 vs 0. 353 3 ± 0. 025 8,t = 15. 644,P = 0. 000;0. 606 7 ± 0. 030 1 vs 0. 270 3 ± 0. 019 4,t = 22. 450,P = 0. 000). In non - treated group,the LC3 expression of cells in the cerebral cortex of rats was up - regulated,and the LC3 - Ⅱ/ LC3 - Ⅰ ratio was significantly higher than that in sham operation group and Dexamethasone group(0. 413 3 ± 0. 022 5 vs 0. 205 0 ± 0. 015 2,t = 18. 802,P = 0. 000;0. 413 3 ± 0. 022 5 vs 0. 185 0 ± 0. 023 5,t = 17. 206,P = 0. 000). The LC3 positive neurons in the cerebral cortex of rats were less in sham operation group and Dexamethasone group. The LC3 positive neurons were more in non - treated group than that in sham operation group and Dexamethasone group(0. 580 0 ± 0. 020 0 vs 0. 298 3 ± 0. 014 7,t =27. 783;P = 0. 000;0. 580 0 ± 0. 020 0 vs 0. 261 7 ± 0. 017 2,t = 28. 614;P = 0. 000). Conclusions The LC3 expres-sion of cells in the cerebral cortex of juvenile Wistar rats with sepsis was up - regulated,LC3 - Ⅱ/ LC3 - Ⅰ ratio in-creased,and the number of LC3 positive neurons also increased,while Dexamethasone could have inhibitory effect on them.

Objective To investigate the correhtion between cognitive impairment and cerebral atherosclerosis in patients with acute ischemic stroke.Methods Acute ischemic stroke patients without cognitive impairment were recruited before symptom onset.The Montreal cognitive assessment (MoCA) was used to evaluate the cognitive function.Magnetic resonance imaging (MRI) was used to identify the infarct locations and sides.Magnetic resonance angiography,CT angiography and digital subtraction angiography were used to identify atherosclerotic arteries.Resul~ A total of 101 patients with acute ischemic stroke were enrolled,including 75 (74.3％) with cognitive impairment.The proportions of age (54.54 ± 12.59 years vs.64.43 ± 10.37 years;t =-3.960,P ＜0.001),years of education ≤6 years (50.7％ vs.11.5％;x2 =12.257,P ＜ 0.001),and cerebral atherosclerosis (89.3％ vs.50.0％;x2 =18.137,P ＜0.001) of the cognitive impairment group were significantly higher than those of the normal cognitive function group.Multivariate logistic regression analysis showed that cerebral atherosclerosis was an independent risk factor for cognitive impairment in patients with acute ischemic stroke (odds ratio 1.720,95％ confidence interval 1.005-2.942;P=0.048).MoCA score was negatively correlated with the offending vessels (r=-0.365,P＜ 0.001) and the most severe vessels of atherosclerotic degree (r=-0.243,P =0.014).Conclusions Most patients with acute ischemic stroke had cognitive impairment in the early stage after onset,and the MoCA scores was negatively correlated with the degree of cerebral atherosclerosis.Cerebral atherosclerosis was an independent risk factor for cognitive impairment in patientswith acute ischemic stroke.

Objective To study the relationship between analgesic effect of total alkaloids in Papaver nudicaule(TAPN) and prostaglandins(PGs) with opium receptors.Methods The analgesic effect of TAPN was studied by hot-plate, writhing,electric-evoked methods of mice.The analgesic mechanisms of TAPN and PGs with opium receptors were studied by the writhing numbers induced by different substances(Ach,AA,MgSO_4),the PGE_2 level in celiac fluid in mice after treated by AA writhing test and the antagonistic experiment of Naloxone.Results The inhibitory effect of TAPN on the writhing induced by Ach and AA in mice was stronger than that induced by MgSO_4.TAPN could also lower the PGE_2 level in celiac fluid.In the antagonistic experiment of Naloxone,no antagonism to the analgesic effect of TAPN had been found by ip or icv Naloxone.Conclusion It may be the mainly peripheral analgesic mechanism that TAPN could lower the PGE_2 level in celiac fluid.Its central analgesic mechanisms are not related to opium receptors.

Objective To study the analgesic sites and mechanism of total alkaloids in Papaver nudicaule (TAPN). Methods The sites of analgesic action of TAPN were observed by adopting Formalin test and two different routes of intracerebroventricular (icv), intrathecal (ith) in mice and rats and comparing ED 50 of TAPN in writhing reaction in mice induced by acetic acid by ip and iv administration. Results TAPN significantly lowered pain score of the early and late phase of Formalin response and was more sensitive in the late phase. Inhibition of TAPN at the same dose by ip administration in writhing reaction in mice induced by acetic acid was stronger than that by iv. The ED 50 value of TAPN at any time by ip administration was lower than that by iv administration. By means of central microinjection, TAPN by icv administration induced remarkable analgesic effect in mice, but TAPN by ith administration had no significant analgesic effect. Conclusion The sites of analgesic action of TAPN are mainly at periphery. TAPN has also central analgesic effect, and the site may be at the level above the spinal cord.
