[Summary] The ossification of the posterior longitudinal ligament ( OPLL ) is caused by environmental , genetic and other factors.With the development of genomics research , researchers have found that mutations are important factors inducing OPLL . Despite the genomics research on OPLL has made important advances , no highly correlation has been found between OPLL and the exact single nucleotide polymorphisms (SNPs) loci.The pathogenesis of OPLL needs further exploration .

AIM: To explore regulation of lipopolysaccharide (LPS)-induced elevation of Ca 2+ intracellular level in alveolar macrophages(AMs) from patients with chronic bronchitis by Angelica Sinensis and nifedipine.METHODS:AMs was obtained from 7 patients with chronic bronchitis and 6 normal controls by bronchoalveolar lavage and intracellular Ca 2+ level was detected after adding Angelica Sinensis, nifedipine or LPS to the supernatant of AMs loaded by Fura-2. RESULTS: In contrast with normal control group (99.65?32.21 nmol/L), intracellular Ca 2+ level in AMs from chronic bronchitis group (189.47?23.69 nmol/L) was increased significantly in the absence of extracellular Ca 2+ but not 1 mmol/L. Intracellular Ca 2+ level in AMs from chronic bronchitis group were significantly increased by adding 10 ?g/mL LPS to the supernatant of AMs. LPS-induced elevation of intracellular Ca 2+ level in AMs from chronic bronchitis group was completely inhibited by Angelica Sinensis or nifedipine.CONCLUSION: Both Anelica Sinensis and nifedipine may inhibit activation of AMs from patients with chronic bronchitis by reducing LPS-induced elevation of intracellular Ca 2+ level in AMs, suggested that these two medicines may inhibit non-specific inflammation of airways in chronic bronchitis.

OBJECTIVETo observe the inhibiting effect of acupuncture on blood lipid, myocardial hypertrophy and fibrosis in mice with hyperlipemia, and explore its possible action mechanism.

METHODSTen inbred mice (C57) were applied. Forty ApoE(-/-) mice who removed gene of apolipoprotein E were randomly divided into a control group, a non-acupoint group, an acupoint group and a medication group. The points 0. 5 cm and 1 cm next to the end of mice tail were respectively punctured in the non-acupoint group; "Neiguan" (PC 6) and "Fenglong" (ST 40) were punctured in the acupoint group; intragastric administration of simvastatin was applied in the medication group. After 8 weeks of treatment, the changes of total cholesterol (TC) and ratio of heart to body mass in each group were measured; changes of cardiac muscle fiber and ventricular wall thickness were observed; enzyme linked immunosorbent assay (ELISA) was used to test the level of angiotensin II (Ang I ) in plasma, and western blotting method was used to test protein content of angiotensin II type 1 receptor (AT1R) and endothelin-1 type A receptor (ETAR) in the heart.

RESULTSAfter 8 weeks of intervention, compared with the control group, rising range of blood lipid was obviously decreased (P<0.01) in the acupoint group and medication group, ratio of P<0.01), myocardial heart to body mass was decreased (P<0.05), thickness of ventricular wall was reduced (P fibrosis was relieved, levels of Ang II and ET-1 in plasma were decreased (P<0. 05), content of NO was increased (P<0. 05), and protein content of AT1R and ETAR was decreased in the heart (P<0. 05).

CONCLUSION40) could inhibit the rising of blood lipid in ApoE(-/-) mice, lower the levels of Ang II and ET-1 in peripheral blood, increase the content of NO and inhibit the expression of AT1R and ETAR in heart tissue, which could relieve myocardial hypertrophy and fibrosis to play a protective role on heart.

OBJECTIVEBy using the metabonomics method, to study the plasma metabonomics of the stable phase chronic obstructive pulmonary disease (COPD) patients of Fei-qi deficiency syndrome (FQDS), and of Chinese materia medica (CMM) intervention, thus exploring possibly existent biomarkers.

METHODSForty stable phase COPD patients of FQDS were recruited as Group A. Liuwei Buqi Capsule (LWBQC) was given to them as intervention. A healthy control group (Group B, 37 cases) was set up. The pulmonary function test was performed on patients in Group B and Group A before and after intervention. The plasma metabolites were detected using high performance liquid chromatography-mass spectrometry (HPLC-MS/MS). Statistical data were analyzed using principal component analysis (PCA) and partial least squares (PLS). The original spectrum and data of plasma metabonomics were compared between the two groups. The whole spectrum amino acid metabonomics tests were performed in the two groups.

RESULTSCompared with Group B, the pulmonary function significantly decreased before intervention in Group A (P < 0.05). The pulmonary function was more mildly improved after 30 days' treatment than before treatment, but still lower than it in Group B (P < 0.05). The metabolic spectrum before treatment in Group A was significantly different from Group B, but showing regressive trend to Group B after treatment. Fifteen possible disease markers were found in COPD patients of FQDS. Results of the whole spectrum of amino acid metabolomics showed different features.

CONCLUSIONSThe changes of metabolic spectrum and amino acids could be found in the stable phase COPD patients of FQDS using plasma metabonomics, and potential markers could be detected. The intervention of the stable phase COPD patients of FQDS by Chinese medicine could brought positive changes in the metabolic profiling and amino acid metabolism.

OBJECTIVETo summarise the clinical features of 18 cases with acute trichloropropane (TCP) poisoning for improving the diagnosis and treatment of the disease.

METHODSExposure history, clinical manifestations, laboratorial examinations, poisoning causes and treatment were retrospectively reviewed in 18 cases with acute TCP poisoning. The results of peripheral lymphocyte micronucleus tests were compared with the healthy control group (n = 33).

RESULTSThe common clinical symptoms were as following: respiratory symptoms were the earlier one set, such as chest tightness in 13, dry and sore throat in 7, cough and runny nose in 2. Gastrointestinal symptoms were more common, such as abdominal pain in 18, nausea and vomit in 14. Only 1 out of 18 patients was found with liver injury. The major manifestation was the increase in ALT and AST, which was returned to normal after treatment. ALL of the 18 patients were found TCP in their serum which concentration was from 39.0 to 310.0 ng/ml, and the average was (68.9 ± 42.1) ng/ml. The symptoms of toxic peripheral neuropathy were typical in all the patients, such as fatigue and numb limb in 18, burning pain of the distal lower limbs in 14, the symmetrical sock-like sensory dysfunction of pain, touch and vibration of the lower limbs in 13, muscle strength reduced in 7, hyporeflexia knee-jerks in 4, hyporeflexia ankle-jerks in 3. The peripheral nerve conduction velocity (NCV) examinations were as followed: the (sensore-nerve conduction velocity) SCV of peroneus super nerve in 18 and the (motor-nerve conduction velocity) MCV of tibial nerve in 8 was slowed down and the distal latency in 18 was prolonged. Micronucleus were found in all 18 cases. The micronucleus rate was 10.06‰ ± 2.80‰ and 8.24‰ ± 2.67‰ in acute TCP poisoning group and healthy control group, respectively. The difference was significant (P < 0.05).

CONCLUSIONThe common clinical manifestations of respiratory exposure of TCP poisoning patients were respiratory symptoms, gastrointestinal symptoms and the symptoms of toxic peripheral neuropathy. Liver injury in those 18 cases was not obvious. Lymphocyte micronucleus of peripheral blood were found in all 18 cases.

Using the weight-average molecular weight 50 000 polylactic acid (PLA) as a carrier, and a certain proportion of erythromycin (EM) and prednisone acetate (PNA) to mixed prepare the compound erythromycin sustained release preparation (sustained-release tablets). Using ultraviolet spectrophotometry and high performance liquid chromatography (HPLC) to detect separately the release amount of EM and PNA in vitro medium. The sustained-release tablets release for about 21 days, the average content of EM is 99.7 mg/table, RSD = 0.82%; and the average content of PNA is 10.03 mg/table, RSD = 0.93%. Within 21 days, the cumulative releases of EM and PNA are 86.1% and 78.3%, respectively. The drug release is steady and slow after 5 days, the burst release phenomenon in early stage is more significant. The results showed that the sustained-release tablet preparation method is feasible, the release performance is good and the clinical efficacy is significant.

OBJECTIVESTo evaluate the long-term facial nerve function of patients following microsurgical removal of large and huge acoustic neuroma, and to identify the factors that influence these outcomes.

METHODSA retrospective review was performed which included 176 consecutive patients with a large acoustic neuroma (≥ 30 mm) underwent a retrosigmoid craniotomy for tumor resection between January 2002 to November 2009. House-Brackmann (HB) Scale was used preoperatively and in a long-term follow-up after surgery. Test for linear trend was applied for statistic analysis.

RESULTSComplete resection was achieved in 168 (95.5%) of these 176 patients with a mortality of 1.7%. Anatomic preservation of the facial nerve was attained in 96.0% of the patients. In the series of 96 patients who had at least 1-year follow-up (mean 3.0 years) the facial nerve function preservation (HB grade 1 - 2) was totally attained in 79 patients (82.3%), and 40 of 55 patients (72.7%) who presented huge tumors (diameter > 40 mm) among the 96 patients had facial nerve function preserved. Analysis showed that facial nerve function correlated linearly with tumor sizes (χ(2) = 14.114, ν = 1, P < 0.05).

CONCLUSIONSComplete removal of large and giant acoustic neuroma may be obtained via retrosigmoid approach with facial nerve preservation. Excellent long-term facial function can be expected in the majority of patients who undergo microsurgical removal of vestibular schwannoma via the suboccipital retrosigmoid approach. Tumor size is a significant prognostic parameter for facial nerve function following vestibular schwannoma surgery.

OBJECTIVETo evaluate the effect of rosuvastatin on the functions of the surviving myocardium and arteriosclerosis plaque in patients with ST-segment elevation after acute myocardial infarction (STEMI) and percutaneous coronary intervention (PCI).

METHODSSixty-five STEMI patients were randomized to receive 40 mg simvastatin (n=32) or 10 mg rosuvastatin (n=33) before sleep in addition to conventional medications. Before PCI and after the 12-month medications, the plasma levels of total cholesterol, low-density lipoprotein cholesterol (LDL-C), C-reactive protein (CRP) and tumor necrosis factor-α (TNF-α) were measured, and echocardiography and (99)Tc(m)-MIBI single-photon emission computed tomography (SPECT) were performed to assess the therapeutic effects.

RESULTSAt the end of 12 months, the patients in simvastatin group showed significantly reduced total cholesterol, LDL-C, CRP, TNF-α, and (99)Tc(m)-MIBI uptake fraction. In rosuvastatin group, these reductions were even more obvious; the intima media thickness (IMT) of the common carotid artery was reduced significantly after a 12-month rosuvastatin therapy, but almost remained unchanged after simvastatin therapy.

CONCLUSIONRosuvastatin therapy in addition to conventional medications can significantly reduce IMT and improve the functions of the surviving myocardium in patients with STEMI after PCI.
