Objective: To explore the urgent management strategy for quadriplegia following China Wenchuan earthquake under filed condition. Methods: The 57-year-old male patient was sent to the earthquake relief team of Changzheng Hospital, Second Military Medical University. He was hit by heavy object during the Sichuan earthquake 6 days ago. Physical examination revealed cervical spinal cord injury accompanied by incomplete paralysis. The patient underwent cervical 3-7 laminectomy under general anesthesia. Results: After surgery the muscle strength of lower limbs recovered to grade four from grade one; the muscle strength of upper limbs recovered to grade five from grade three. Sensory loss was found below the nipple level and totally recovered after operation. Conclusion: Early surgery for quadriplegia following earthquake trauma can timely relieve compression to the spinal cord and therefore improve prognosis of patients. Under field condition where facilities are not readily available, decompression of spinal cord can be achieved by laminectomy via posterior approach. The key to successful operation is correct diagnosis and skillful manipulation.

AIM: To compare the contents of baicalin,paeoniflorin and glycyrrhetic acid in the seperated and mixed decoction of Huangqin Decoction(Radix Scutellariae,Radix Paeoniae alba,Radix et Rhizoma Glycyrrhizae and Fructus Jujubae). METHODS: The contents of baicalin,paeoniflorin and glycyrrhetic acid were analyzed by HPLC.Chromatographic conditions included: Hypersil BDS C_(18) column and the mobile phase consisted of a mixture of methanol-water-phosphoric acid(47(∶)53(∶)0.2),acetonitrile-water-phosphoric acid(18(∶)82(∶)0.1) and methanol-water-phosphate buffer solution(70(∶)29(∶)1).Baicalin,paeoniflorin and glycyrrhetic acid were detected at 280 nm,230 nm and 250 nm respectively. RESULTS: The linear range of baicalin,paeoniflorin and glycyrrhetic acid were 2.88—72.00 ?g/mL,2.85—22.80 ?g/mL and 4.16—52.00 ?g/mL respectively.The contents of baicalin in the mixed decoction was higher than that in the seperated decoction.The contents of paeoniflorin and glycyrrhetic acid in the mixed decoction were almost as same as that in seperated decoction. CONCLUSION: The contents of active ingredients in the mixed and seperated decoction are different.

Objective To investigate the effect of the nuclear factor (NF)-κBp65 antisense oligonucleotide (ASODN) on NF-κB activity and expression of interleukin(IL)-6 in hepatic stellate cells (HSC). Methods The HSC were separated from rats and cultured. The toxicity of NF-κBp65 ASODN on HSC were detected by Trypan blue exclusion staining and the NF-κB activity was determined by EMSA. The expressions of IL-6 mRNA and protein were meaured by RT-PCR and ELISA, respectively. Results In vitro, no toxicity of ASODN on HSC was observed at the concentrations of 0. 001 to 1.0 μmol/L. NF-κB activity was increased after stimulating HSC with tumor necrosis factor (TNF)α, whereas it was weakened in a dose dependent manner when HSC were cultured with ASODN (concentration from 0. 001 to 1.0 μmol/L). At the same time, the expressions of IL-6 mRNA and protein induced by TNFα were decreased after transfected with ASODN at concentrations of 0.001- 1. 0 μmol/L in a dose dependent manner. Conclusion ASODN may specifically inhibit either the activiy of NF-κB or expression of IL-6, which provides the theoretical basis that ASODN may use to treat fibrosis of the liver.

OBJECTIVETo compare the differences between computer aided identification and ultra-thin layer slicing in measuring the lesions of femoral head necrosis,and to confirm the accuracy and practicability of computer aided method.

METHODSFrom June 2012 to December 2013, the X-ray and MRI of 24 patients (24 hips on unilateral) were reviewed, who had avascular necrosis of the femoral head (ANFA) at late stage (stage III and IV) according to the ARCO international staging system. There were 15 males and 9 females, with an average age of (65.1 ± 8.8) years old, ranged 33 to 74 years old. Based on the software system with seeds point identification, the ragional adaptive search method with computer aid was used to calculate the volume of necrotic lesion in femoral on MRI. Then the pathological slices of those intraoperative femoral heads were made to measure the gross volume of necrotic lesion in femoral head,and the values were compared with the data in the computer.

RESULTSFor 24 hips, by the calculation of computer, the necrotic volume was (20.00 ± 3.04) cm (ranged, 18.72 to 21.29 cm³). Under the pathological section, the necrotic volume of the femoral head was (19.89 ± 3.17) cm³ (ranged, 18.55 to 21.23 cm³). In computer and pathology two kinds of measurement, the two entire femoral head volume had no significant difference using these two measurements (t = -1.227, P = 0.232).

CONCLUSIONComputer aided identification for necrotic area of femoral head adaptive can demonstrate the morphology of femoral head necrosis accurately and reliably, which will help surgeon better understand the morphology and orientation in femoral head.

OBJECTIVETo explore the mechanism of Astragalus polysaccharides (APS) for improving the cardiac function of Sjogren's syndrome (SS) model rats based on Keapl-Nrf2/ARE signaling pathway.

METHODSTotally 48 male Wistar rats were randomly divided into four groups by random digit table, i.e., the blank control group,the model control group,the APS group, and the hydroxychloroquine group, 12 in each group. Except those in the blank control group, 0. 1 mL mixed antigen protein of sufficiently emulsified Freund's complete adjuvant and submandibular gland protein was injected from two feet plantar to induce SS model. The intervention was started from 19th day after inflammation induction. Equal volume of normal saline was given to rats in the blank control group (1 mL/100 g), APS was administered to those in the APS group (1 mg/100 g), and hydroxychloroquine (0.03 125 g/kg) was administered to those in the hydroxychloroquine group. All rats were intervened once per day for 30 consecutive days. Changes of rats' body mass and drinking water quantity, submandibular gland index, spleen index, histological changes of glands were observed. Changes of the heart function were monitored using invasive hemodynamics. Serum reactive oxygen species (ROS), malondialdehyde (MDA), superoxide dismutase (SOD), total antioxidant capacity (TAC), tumor necrosis factor alpha (TNF-alpha), and interleukin-35 (IL-35)were detected using ELISA method. The pathological changes were observed using HE staining. The protein expression of ROS, reactive nitrogen species (RNS), glutathione (GSH), and thioredoxin (TRX) were observed by immunohistochemical staining. The mRNA expression of Keap1, Nrf2, and ARE was detected using real time fluorescent quantitative PCR. The protein expression levels of gamma-glutamic acid and a half long glycine synthetase (gamma-GCS) and heme oxygenase 1 (HO-1) in the myocardial tissue were determined by Western blot method. Results Compared with the blank control group, the quantity of drinking water, submandibular gland index, spleen index, heart rate (HR), cardiac index (HI), left ventricular systolic pressure (LVSP), left ventricular diastolic pressure (LVEDP), MDA, ROS, TNF-alpha, ROS protein expression, RNS protein expression, Keap 1 mRNA expression, Maf mRNA expression, Nfr2 mRNA expression, and HO-1 protein expression, and gamma-GCS protein expression significantly increased (P <0.01); body mass, +/-dp/dtmax, SOD, TAC, IL-35, GSH, and TRX significantly decreased (P <0.01) in the model group. Compared with the model group, the quantity of drinking water, submandibular gland index, spleen index, LVEDP, MDA, ROS, TNF-alpha, ROS protein expression, RNS protein expression, Keap1 mRNA expression, Maf mRNA expression, Nfr2 mRNA expression, and HO-1 protein expression, and gamma-GCS protein expression significantly decreased (P<0.05); body mass, +/-dp/dtmax, SOD, TAC, IL-35, GSH protein expression, and TRX protein expression significantly increased (P < 0.05, P <0.01) in the AR group and the hydroxychloroquine group. In the hydroxychloroquine group HR increased (P <0.05). In the AR group HR and LVSP decreased (P <0. 05, P <0. 01). Compared with the hydroxychloroquine group, HR, LVEDP, - dp/dtmax, y-GCS protein expression significantly decreased (P <0. 05, P <0. 01); SOD, TAC, GSH, TRX, HO-1 protein expression increased (P <0.01 )in the AR group. HI was positively correlated with ROS (P <0. 05). LVSP and LVEDP were positively correlated with Keap1 -Nrf2/ARE signaling pathways (P <0. 01) , and negatively correlated with TAC (P <0. 05, P <0. 01 ). +/-dp/dtmax was negatively correlated with Keap1-Nrf2/ARE signaling pathways(P <0.05), and positively correlated with TNF alpha (P <0. 05).

CONCLUSIONSDeclined heart function exists in SS rats. The mechamechanism of APS for improving the heart function might be closely correlated with activating Keap1-Nrf2/ARE signaling pathway.
