Objective To explore the expression of c-Fos protein and character of mossy fiber sprouting(MFS) in hippocampus of rat with febrile seizures(FS).Methods Thirty-six 21-day-old male Sprague-Dawley rats were randomly divided into FS group,febrile control(FG) group and normal control(NG) group.FS was established by hyperthermal bath.Immune histochemistry and(Timm′s) staining were used to examine the expression of c-Fos protein in CA1 region and MFS in CA3 region of hippocampus.Results Excessive expression of c-Fos protein presented in the hippocampal CA1 region of FS group.The surface area percentage of c-Fos protein of FS group[(2.26?0.23)%] was higher than that of FG group[(1.08?0.19)%] and NG group[(0.71?0.14)%],there were significant difference between FS group and the other two groups(?~2=10.48 P

OBJECTIVETo observe the effect of Panax notoginseng saponins (PNS) on serum content of neuronal specific enolase (NSE) and function recovery in patients with cerebral hemorrhage (CH) for exploring the therapeutic action of PNS in treating CH.

METHODSFifty CH patients with their course of disease not more than 5 days were randomly assigned to two groups, 27 in the PNS group and 23 in the control group, all were treated with conventional treatment, while PNS was given additionally to the PNS group. The serum levels of NSE before and after treatment were determined by electrochemiluminescence, and the recovery of patients, including their neuro-function deficit and daily living activity, was assessed according to scoring by the National Institute of Health Stroke Scale (NIHSS) and Barthel Index (BI) respectively.

RESULTSBefore treatment, the difference between the two groups in serum NSE content and scores of NIHSS and BI was insignificant (P > 0.05). However, after 3 weeks of treatment, the level of NSE and score of NIHSS were significantly lower, while score of BI was significantly higher in the PNS group than those in the control group respectively (all P < 0.01). In the PNS group, the level of NSE showed a positive correlation with the score of NIHSS (r = 0.757, P < 0.05), and a negative correlation with the score of BI (r = - 0.803, P < 0.05).

CONCLUSIONPNS can effectively protect the neuron and promote functional rehabilitation in patients after CH.

BACKGROUND: Pulmonary stretch reflex plays an important role in regulation of respiratory movement. This study aimed to evaluate the effect of pulmonary stretch reflex on lung injury in rabbits with acute respiratory distress syndrome (ARDS). METHODS: ARDS rabbits were given intratracheal infusion of hydrochloric acid and ventilated with neurally adjusted ventilatory assistance (NAVA) with a tidal volume (VT) of 6 mL/kg and the electrical activity of diaphragm (EAdi)-determined positive end expiratory pressure. After isolation of the bilateral vagusnerve trunk, the rabbits were randomized into two groups: sham operation (SHAM) group (n=5) and bilateral vagotomy (VAG) group (n=5). Gas exchange and respiratory mechanics were detected at baseline, after lung injury and 1, 2, and 3 hours after ventilation respectively. Pulmonary permeability index, pathological changes and inflammatory response were also measured. RESULTS: Compared with the SHAM group, PaO2/FiO2 in the VAG group decreased significantly 2 and 3 hours after ventilation (P<0.05). There was no significant difference in PaCO2 between the SHAM and VAG groups (P>0.05), and the VAG group had a high VT, peak pressure (Ppeak), and mean pressure (Pm) compared with the SHAM group 1, 2, 3 hours after ventilation (P<0.05). Compared to the SHAM group, dead space fraction (VD/VT) and respiratory system elastance (Ers) in the VAG group increased (P<0.05) and static pulmonary compliance (Cst) decreased markedly (P<0.05) after ventilation for 3 hours. Lung wet/dry weight ratio (W/D) (8.4±1.2 vs. 6.6±1.0), lung injury score (6.3±1.8 vs. 3.8±1.3), tumor necrosis factor-α (TNF-α) (779±372 pg/mL vs. 355±130 pg/mL) and interleukin-8 (IL-8) (169±21 pg/mL vs. 118±17 pg/mL) increased significantly in the VAG group compared with the SHAM group (P<0.05). CONCLUSION: Lung injury is aggravated after bilateral vagotomy, demonstrating that pulmonary stretch reflex may have protective effect on the lung.

OBJECTIVETo introduce the experience in the treatment of lower eyelid pouches orbital rim.

METHODSAn incision was made along the margin of lower eyelid and dissection was performed under the orbicularis muscle to expose the orbital septum and periosteum of lower orbital rim. The fat released from orbital septum was transposed just below the lower orbital rim and fixed on the periosteum. If lacrimal groove deformity was not corrected completely, the musculocutaneous flap, which may be excised beside the incision, was kept to correct the deformities further with only the muscle portion.

RESULTS72 cases with lower eyelid pouches complicated with lacrimal groove deformities were treated with transposition of orbital fat and orbicularis muscular flaps. Satisfactory results were achieved in all the patients after a follow-up period of 3-6 months.

CONCLUSIONIt is an effective and feasible technique to correct lacrimal groove deformities with transposition of orbital fat and orbicularis muscular flaps.

1,2,3,4,6-penta-O-galloyl-D-glucose (PGG) is one of the main active compounds of Guizhi Fuling capsule. Molecularly imprinted polymers (MIP) have high affinity toward template molecules synthesized by molecularly imprinted technology for its specific combined sites, which can overcome the shortcoming of traditional separation methods, such as complex operation, low efficiency, using large quantity of solvent and environmental pollution. In this paper, surface molecularly imprinted polymer (SMIP) was prepared by surface imprinting with PGG as the template molecule. Its adsorption capacity was measured by the scatchard equation. The separation of PGG from Guizhi Fuling capsule at preparatived scale was achieved with molecularly imprinted polymer as stationary phase and the purity was 90.2% by HPLC. This method can be used to prepare PGG from Guizhi Fuling capsule with large capacity and is easy to operate. It provides a new method for efficient separation and purification for other natural products.

OBJECTIVETo study the plasma homocysteine (Hcy) distributive characteristics in different sex and age groups of the community residents in Guangdong, and to analyze its associated factors as well as its effects on cerebral artery stenosis.

METHODSIn this study, we presented data concerning 2500 residents who had undergone a systematic health checkup,including clinical and biologic examinations. Plasma was saved from 1020 residents who were asymptomatic but having TCD examination. Hcy concentration was measured by fluorescence ration biochemical assay kit.

RESULTSThe average plasma Hcy levels of males (15.0 micromol/L+/-5.8 micromol/L) were significantly higher than those of females (12.4 micromol/L-I 3.9 micromol/L, P< 0.05). Hcy level increased parallel with age. The prevalence rate of hyperhomocysteinemia in males (47.2%) was higher than in females (23.2%). Hcy levels in MCA stenosis group (18.3 micromol/L+ 5.3 micromol/L) were significantly higher than that in control group (12.9 micromol/L+/- 4.6 micromol/L, P< 0.05). Based on logistic regression analysis, Hcy was only associated with sex and age, but not with blood lipids etc.

CONCLUSIONHcy levels were different in sex and age groups which emerged as independent predictors of hyperhomocysteinemia but had no association with blood lipids in the community residents, suggesting that hyperhomocysteinemia might worsen cerebral artery stenosis.

OBJECTIVETo investigate the quality of life (QOL) and its influence factors in epilepsy patients in Zhuang population in Guangxi Guixi area.

METHODSTotally 78 epilepsy patients in Zhuang populations and 60 healthy controls were enrolled, and their QOL was assessed with Quality of Life in Epilepsy Inventory-31 (QOLIE-31). The QOLIE-31 scores of patients between different sexes, anti-epileptic drugs (AEDs) usage, duration of seizure, and seizure types were compared.

RESULTSQOL score was significantly lower in epileptic group (53.9 +/- 8.0) compared with control group (77.0 +/- 7.1) (P < 0.01). No difference was found in QOLIE-31 scores of patients between men and women (P > 0.05). Patients with single AED, shorter duration of seizure, and tonic-clonic seizure had higher QOLIE-31 scores than those with multiple AEDs, longer duration of seizure, and other seizure types (P < 0.01, P < 0.05, P < 0.01, respectively).

CONCLUSIONSQOL is lower in epilepsy patients than normal people in Zhuang populations in Guangxi Guixi area. Medication and seizure type affects the QOL in patients with epilepsy.
