The 125I-acetylated low density lipoprotein (125I-Ac-LDL for ScR-A) and 125I-oxidized low density lipoprotein (125I-Ox-LDL for CD36) uptaking (including 4℃ binding,37℃ association and degradation) were measured respectively.Influence of anti TGF-?1 antibody (Anti TGF-?1 Ab) on the ScR-A and CD36 mRNA expressions in THP-1 derived macrophages was measured meanwhile,respectively.Results Compared with control group ( binding: 8.23 ?g?g-1 ?1.24 ?g?g-1 protein,association:45.69 ?g?g-1 ?6.92 ?g?g-1 protein,and degradation: 112.18 ?g?g-1 ?20.15 ?g?g-1 protein),Anti TGF-?1 Ab increased 125I-Ac-LDL binding(48.67 ?g?g-1 ?6.52 ?g?g-1 protein),association (412.30 ?g?g-1?12.21 ?g?g-1 protein),and degradation (896.48 ?g?g-1 ?32.74 ?g?g-1 protein) significantly (P

Objective To investigate the diagnostic value of combination of echocardiography with electrocardiography for coronary artery lesions(CAL) in Kawasaki disease(KD).Methods Seventy eight children with KD received echocardiographic and electrocardiographic examination.Seventy eight cases were divided into 3 groups according to the results of echocardiogram.Results CAL was discovered in 45 cases and 32 cases with coronary artery dilation,the other 13 cases with coronary artery aneurysm among them.Abnormal electrocardiogram was found in 16 cases.ratio of abnormal electrocardiogram was higher in CAL group than that in normal coronary artery group(P

OBJECTIVETo compare the difference in the clinical efficacy on primary trigeminal neuralgia (PTN) between the comprehensive therapy of electroacupuncture (EA) at qi streets acupoints combined with spinal regulation method and medication with carbamazepine (CBZ).

METHODSSixty patients were randomized into a comprehensive therapy group (30 cases) and a medication group (30 cases). In the comprehensive therapy group, the acupoints at qi streets on the head such as Taiyang (EX-HN 5) and Sishencong (EX-HN 1) and those at qi streets on the chest and abdomen such as Shenshu (BL 23), Zhongwan (CV 12) and Guanyuan (CV 4), etc. were selected. After arrival of qi, EA was attached on 2 to 4 groups of acupoints. After acupuncture, the spinal regulation method was applied. This comprehensive therapy was given once a day. In the medication group, CBZ was used for oral administration, 100 mg at the first time, twice a day, and 400 to 600 mg each day as the maintenance dose. Separately, before and after treatment, in 2 and 6 months in follow-up, pain rating index (PRI), life satisfaction index B (LSI-B) and hamilton depression scale (HAMD) were adopted to evaluate comprehensively the clinical efficacy in the two groups and compare the adverse reaction during the treatment between the two groups.

RESULTSAfter treatment, the curative and markedly effective rate in the comprehensive therapy group was 76.7% (23/30), which was better than 63.3% (19/30) in the medication group (P < 0.01). The difference in PRI was not significant after treatment between the two groups (all P > 0.05). In 2 and 6 months follow-up, PRI grade in the comprehensive therapy group was superior to that of the medication group (both P<0. 05). After treatment and in follow-up, HAMD score was all reduced in the two groups (P < 0.01, P < 0.05) and the result in follow-up in the comprehensive therapy group was significant as compared with that in the medication group (all P<0. 05). After treatment, LSI-B score was increased obviously in the two groups (all P < 0.05) and the result in the comprehensive therapy group was better than that in the medication group (P < 0.05). The incidence of adverse reaction in the comprehensive therapy group was 16.7% (5/30), which was lower than 30.0% (9/30, P < 0.01) in the medication group.

CONCLUSIONThe comprehensive therapy of EA at qi streets acpoints combined with spinal regulation method achieves the long-term efficacy on PTN as compared with oral administration of CBZ in terms of the improvement of psychological condition, analgesia and life quality. It is the safe, effective and stable therapy.

OBJECTIVETo compare the clinical efficacy difference between electroacupuncture (EA) at qijie area combined with spine balance-regulating massage and medication for posterior circulation ischemia (PCI).

METHODSOne hundred cases of PCI were randomly divided into a treatment group (50 cases) and a medication group (50 cases). The treatment group was treated with EA at Baihui (GV 20), Sishencong (EX-HN 1), Fengchi (GB 20), Shenshu (BL 23), Danzhong (CV 17), etc. in qijie area combined with spine muscle-relieving massage and comprehensive chiropractic. The medication group was treated with oral administration of nimodipine (30 mg per time, three treatments per day) and vinpocetine injection with 500 mL of glucose injection or intravenous drip of 500 mL 0.9% sodium chloride injection, once a day. Ten treatments were taken as one course in both groups, and two courses were given. The symptom score, mean resistance index (RI) of vertebral artery (VA) and basilar artery (BA), mean velocity of blood flow (Vm) and comprehensive clinical efficacy were compared before and after treatment in two groups.

RESULTSThe cured and markedly effective rate was 79.6% (39/49) in the treatment group, which was superior to 54.7% (23/42) in the medication group (P<0.05). The symptom score was both significantly improved after treatment in two groups (both P<0.05), which was more obvious in the treatment group (P<0.05). The RI of VA and BA, Vm of VA and BA were significantly improved after treatment in two groups (all P<0.05), which were more obvious in the treatment group (all P<0.05).

CONCLUSIONThe electroacupuncture combined with spine balance-regulating massage has superior effect on improving mean velocity of blood flow and resistance index of vertebral artery and basilar artery as well as symptom score to medication, and is believed to be a safe and effective treatment for posterior circulation ischemia.

OBJECTIVE: To explore the antitumor activities of kushen (Sophora flavescens) flavonoids (KS-Fs) in vivo and in vitro. METHODS: Cell proliferation was assayed by using methyl thiazolyl tetrazolium (MTT) method. H22 hepatocellular carcinoma and S180 sarcoma were induced in ICR mice. Lewis lung carcinoma was induced in C57BL/6 mice. H460 and Eca-109 tumor were induced in Balb/c nude mice by injecting 5x10(5) or 5x10(6) tumor cells in the right flank, respectively. RESULTS: KS-Fs could inhibit the growth of a variety of human tumor cell lines (A549, SPC-A-1, NCI-H460, etc.) in vitro. The antitumor efficacies were confirmed in the mice models of H22, S180 and Lewis lung tumors and the nude mice models of human H460 and Eca-109 xenografted tumors. The oral or intravenous maximum tolerated dose of KS-Fs was more than 2.8 g/kg or 750 mg/kg respectively, far more than the oral medial lethal dose of kushen alkaloids (< or = 1.18 g/kg). No adverse reactions were observed. CONCLUSION: These results suggest that KS-Fs or kurarinone may be developed as a novel antitumor agent.

Objective To assess the safety of early subcutaneous injection of a low-dose low molecular weight heparin (LMWH) nadroparin for prevention of deep vein thrombosis (DVT) in patients with spontaneous intracerebral hemorrhage (sICH).Methods The patients with sICH who early using nadroparin or lower limb intermittent pneumatic compression (IPC) for prevention of DVT were enrolled.A nadroparin group continuously injected nadroparin 0.4 ml/d subcutaneously for 10 days at day 4 after admission and an IPC group used lower limb IPC.Head CT was reexamined and hematoma volume changes were evaluated at day 3,5,and 14 after admission.The hemorrhagic events during the course of treatment were documented,and the lower limb DVT was examined by color Doppler sonography.Results A total of 94 patients with acute sICH (n =41 in the nadroparin group,n =53 in the IPC group) who early use of nadroparin or IPC for prevention of DVT were enrolled.Fourteen patients had lower limb DVT,5 (12.2％) of them were in the nadroparin group and 9 (17.0％) of them were in the IPC group.However,there was no significant difference in the incidence of DVT between the two groups (x2 =0.418; P =0.518).During the treatment,no patient experienced increased intracranial hematoma and rebleeding.Conclusion Early subcutaneous injection of low-dose nadroparin for the prevention of DVT in patients with sICH is safe.

Objective To analyze the diagnosis and prognosis value of abdominal CT scans in patients with acute pancreatitis complications.Methods 151 cases with acute pancreatitis were selected.The relationship between abdominal CT performances and the common complications and death in patients was analyzed.The prognosis of patients with different Balthazar CT severity index (CTSI) grade was compared.Results The complication rate of patients with CT signs of fatty liver, pleural effusion, liver gap effusion, adrenal gland involvement (AGI), penirenal space involvement (PSI) and gastric bare area involvement (GBAI) was significantly higher than that of patients with negative CT findings above (P<0.05).With CTSI grading increasing, the patient''s fasting time, heating time, hospital stay, recovery time of blood amylase were extended, and the incidence of pseudo cyst, transit surgery, organ failure and death was gradually increasing (P<0.05).Conclusion Severe fatty liver, AGI, GBAI, PSI and liver gap effusion are risk factors for acute complications and death in patients with pancreatitis.

Objective To observe the effects of intermittent hypoxic preconditioning on the expression of apoptosis-related Bcl-2 and Bax protein after 70％ hepatectomy combined with ischemia-reperfusion injury.Methods A total of fifty-four SD rats were randomly divided into three groups (n =18).Partial hepatectomy hroup (PH Group):Rats underwent the left and middle lobectomy of liver(70％ hepatectomy).Ischemia reperfusion group (IR group):The left and middle lobes of liver were resected during the occlusion of the hepatoduodenal ligament for 20 minutes.Residual liver underwent the process of ischemia-reperfusion.Intermittent hypoxia preconditioning group (IHP group):rats were exposed to hypoxic environment of 10％ oxygen for 1 h/d.After 7 consecutive days,the left and middle lobes of liver were resected under the portal triad clamping.At 12,24 and 48 hours after the operation,the rats were killed and detected.The serum levels of ALT and AST were determined by automatic biochemical analyzer.The expression of Bcl-2 and Bax protein in liver tissue were measured by immunohistochemistry.Results At each time point after surgery,the serum levels of ALT and AST in IR group and IHP group were higher than that of PH group,and IHP group were lower than in IR group.Compared with IR group,the expression of Bcl2 protein significantly increased and Bax protein expression significantly decreased in IHP group.All these differences were statistically significant (P ＜ 0.05).Conclusions Intermittent hypoxic preconditioning might protect residual liver against ischemia reperfusion injury,through increasing the expression of Bcl-2 protein and reducing the expression of Bcl-2 protein to decrease liver cell apoptosis.

Objective To investigate the effects of intermittent hypoxic preconditioning on residual liver regeneration after parital hepatectomy in rats.Methods Fifty-four Sprague-Dawley rats were randomly divided into 3 groups (each group contained eighteen animals):sham operation group (SO group),parital hepatectomy group (PH group)and intermittent hypoxic preconditioning group (IHP group).The rats in PH group underwent the left and middle lobectomy of liver(70％ hepatectomy).The rats in IHP group were exposed to hypoxic environment of 10％ oxygen for 1 h/d.And after a week,the rats underwent parital hepatectomy.Six rats in each group were sacrificed respectively on postoperative day 1,3 and 5 (POD 1,3 and 5).The resected liver and the regenerated liver were weighed to calculate liver regeneration degree and regeneration index.The values of alaninea minotransferase (ALT) and aspartate aminotransferase (AST) in the inferior vena venous blood were examined by automatic biochemical analyzer.The positive ratio of hepatocellular proliferating cell nuclear antigen (PCNA) in the residual liver was investigated immunohistochemically.Results The degree and index of liver regeneration in IHP group were respectively higher than those in PH group on POD 1 and 3(P ＜0.05),but there were no statistical differences between the two groups on POD 5.The levels of ALT and AST in PH and IHP group began to decline after surgery,but they remined higher than those in SO group.Moreover,the ALT and AST levels in IHP group were significantly lower than those in PH group on POD 1 (P ＜0.05).The positive ratios of hepatocellular PCNA were respectively higher than those in SO and PH group on POD 1,3 and 5 (P ＜ 0.05).Conclusions To some extent,preoperative intermittent hypoxic preconditioning could prevent hepatocellular damage after parital hepatectomy,what is more,it also could promote the remnant liver regeneration.But the mechanism still needs to be studied furter.
