ObjectiveTo study the effect of Shuanglong pill on expression of vascular endothelial growth factor(VEGF) and basic fibroblast growth factor(bFGF) on aortic atherosclerotic plaque.MethodsAs atherosclerotic(AS) models of rabbits were made by immune injury plus hyperlipid diet, all rabbits were divided into blank control group(group Ⅰ,6), experimental control group(group Ⅱ, 6), captopril control group(group Ⅲ, 6; 10 mg/kg·d,12 weeks), and Shuanglong pill group(group Ⅳ, 6; 2.52 g/kg·d,12 weeks). Quantitive and qualitative analysis of expression of VEGF and BFGF on aortic atherosclerotic plaque were performed.ResultsExpressive area, density and density index of VEGF and bFGF on aortic atherosclerotic plaques were significantly decreased in group Ⅲ and Ⅳ than in group Ⅱ(P<0.01). There were significant decrease for VEGF expression in group Ⅳ than in group Ⅲ(P<0.01).Pathologic staining showed that there were no foam cells formation and no stained yellow in group Ⅰ, but mass foam cells formation and widespread stained yellow in group Ⅱ. There were a small quantity of foam cells formation and little stained yellow in group Ⅲ and group Ⅳ.ConclusionShuanglong pill can delay/reverse AS progression by inhibiting VEGF and bFGF expression in atherosclerotic plaque as well as captopril.

ObjectiveTo explore the effect of Shuanglong pill which can vivid blood and relax thread pulse on cardial morphology and haemodynamics in experimental myocardial infarction (MI) rats.Methods66 rats ligated left coronary artery were randomly divided into large dose group of Shuanglong pill (LDG), small dose group of Shuanglong pill (SDG), the normal control (NC) and the control group of MI. Half in each group received 2 week treatment and the other received 4 week treatment, and were spiled in femoral and common carotid artery respectively. Parameters of cardiac haemodynamics were monitored by eight lead physiological recorder. ResultsLeft ventricular systolic maximum velocity in LDG, SDG and DC was more significantly elevated than in MI, after 2 weeks and 4 weeks of treatment, but it was lower than NC. There were no significant differences among LDG, SDG and DC. Ventricular systolic maximum velocity in LDG was more significantly elevated than in MI after 2 week treatment.ConclusionTreating MI with Shuanglong pill can improve left ventricular systolic maximum velocity, and diastolic phase function of left ventricular also elevate during the acute stage of MI by using large dose.

Results The abnormal rate of EEG was 86.7 % in children with cysticercosis,which mainly showed the diffuse or focal irregularity complex slow waves in frontal lobe,central lobe and anterior lobe.The abnormal rate of CT was 70.8 % in all patients,and flaky and circular focus were chief manifestations.There was a significant difference be- tween the rates of EEG and CT(P

OBJECTIVETo investigate the frequency and type of PHEX gene mutations in children with X-linked hypophosphatemic rickets (XLH), the possible presence of mutational hot spots, and the relationship between genotype and clinical phenotype.

METHODSClinical data of 10 children with XLH was retrospectively reviewed. The relationship between gene mutation type and severity of XLH was evaluated.

RESULTSPHEX gene mutations were detected in all 10 children with XLH, including 6 cases of missense mutation, 2 cases of splice site mutation, 1 case of frameshift mutation, and 1 case of nonsense mutation. Two new mutations, c.2048T>C and IVS14+1delAG, were found. The type of PHEX gene mutation was not associated with the degree of short stature and leg deformity (P=0.571 and 0.467), and the mutation site was also not associated with the degree of short stature and leg deformity (P=0.400 and 1.000).

CONCLUSIONSMissense mutation is the most common type of PHEX gene mutation in children with XLH, and c.2048T>C and IVS14+1delAG are two new PHEX gene mutations. The type and site of PHEX gene mutation are not associated with the severity of XLH.

OBJECTIVETo explore clinical outcomes and advantages of anterior small-incision focus debridement with posterior internal fixation through muscle spa ring in treating patients with lumbar spinal tuberculosis.

METHODSFrom February 2010 to February 2014, totally 82 patients with lumbar spinal tuberculosis were treated by posterior individual fixation with small-incision focus debridement,including 50 males and 32 females with an average of 50.5 years old. All patients were divided into two groups according to different procedures. Forty-nine patients in group A were treated with anterior small-incision focus debridement with posterior internal fixation through muscle spa ring at stage I ; and 33 patients in group B were treated with focus debridement with posterior internal fixation by extraperitoneal approach at stage I . Postoperative mechanical ventilation time, preoperative and postoperative Cobb angle, visual analogue scale (VAS), erythrocyte sedimentation rate (ESR) and Frankel grading were observed and compared. Postoperative complications, stability of internal fixation and bone union were compared.

RESULTSAll patients were followed-up from 15 to 36 months with an average of 23.7 months. Psoas abscess of three patients in group A and 1 patient in group B on the opposite side increased and were healed by the secondary apocenosis. The other 78 cases were healed at stage I, and no sinus tract formation, incisional hernia, leakage of cerebrospinal and occurrence of spinal tuberculosis were occurred. Fracture healing time ranged from 3 to 7 months with an average of 4.6 months. Postoperative mechanical ventilation time and VAS score in group A was better than group B. There were no statistical differences in Cobb angle, ESR and Frankel grading at the final following-up between two groups.

CONCLUSIONAnterior small-incision focus debridement with posterior internal fixation through muscle spa ring in treating patients with lumbar spinal according to degree of damage is a safe and effective method.

OBJECTIVETo observe the efficacy and safety of Danlong Oral Liquid (DOL) combined Western medicine (WM) in treating mild-to-moderate bronchial asthma patients (heat wheezing syndrome) at acute onset.

METHODSTotally 480 mild-to-moderate bronchial asthma patients (heat wheezing syndrome) at acute onset were randomly assigned to two groups in the ratio 3:1, the treatment group (360 cases) and the control group (120 cases). All patients received basic WM treatment. Patients in the treatment group took DOL, 10 mL each time, 3 times per day for 7 days in total, while those in the control group took Kechuanning Oral Liquid (KOL) , 10 mL each time, 3 times per day for 7 days in total. Efficacy for asthma symptoms, lung functions and scores of TCM syndrome and/or main symptoms were evaluated.

RESULTSThe percentage of clinical control and significant effectiveness of asthma symptoms in the treatment group was significantly higher than that of the control group (77.36% vs 56.07%, P < 0.01). The percentage of clinical control and significant effectiveness of lung functions in the treatment group was significantly higher than that of the control group (74.28% vs 50.00%, P < 0.01). The anterior-posterior difference in scores of TCM syndrome was significantly superior in the treatment group than in the control group (-11.26 ± 4.70 vs -9.21 ± 5.09, P < 0.01). The anterior-posterior difference in scores of main symptoms was significantly better in the treatment group than in the control group (-6.58 ± 3.08 vs -5.16 ± 3.45, P < 0.01). The incidence of adverse reactions was significantly lower in the treatment group than in the control group [1.73% (6/346 cases) vs 10.17% (12/118 cases) , P < 0.05].

CONCLUSIONDOL combined WM was superior to KOL in treating mild-to-moderate bronchial asthma patients (heat wheezing syndrome) at acute onset.

Objective To observe the influence of long-term treatment with inhaled corticosteroid on biochemical bone indexes and bone mineral density (BMD) in children with asthma. Methods The design was a randomized, paralleled group study with 3 low dose regiments of 100, 200,300 micrograms of budesonide per day in 45 children with asthma aged 5-8 years old for 12 months. Before inhaled corticosteroid therapy and 6th,12th month,clinical effects were observed and lung function(FEV1) was measured; concentration of serum osteocalcin(OST),insulin-like growth factor-1(IGF-1),bony alkaline phosphatase (BALP) and urinary deoxypyridinolin: creatinine (DPD/Cr) were measured; BMD was examined by dual energy X-ray absorptiometry. Results Clinical evaluation was improved and there was significant increase in FEV1 of asthmatic children. The amount of serum OST was slightly higher,yet no significant compared with that of normal control group. There was significant increase of serum BALP in asthmatic children after treatment; there was significant increase in serum IGF-1 of patients group after treatment compared with in normal children at the same age group; there was significant decrease in urinary DPD/Cr after treatment.There was no significant decrease in BMD before and after treatment at the hip (neck of femur , trochanter of femur ,Ward′s triangle),the lumber area of the spine (L2-4) and forearm (ultradis, distal). Conclusion Long-term treatment with low does corticosteroid dose not restrictedly affect bone metabolism and BMD in children with asthma.

OBJECTIVETo explore the effect of 18-β glycyrrhetinic acid (GA) on the endoplasmic reticulum of nasal epithelial cells in allergic rhinitis (AR) model rats.

METHODSTotally 96 Wistar rats were randomly divided into the blank group, the AR model group, the loratadine group, the GA group, 24 in each group. AR models were established by peritoneally injecting ovalbumin (OVA). Morphological scoring was performed. GA at 21. 6 mg/kg was intragastrically administered to rats in the GA group. Nasal mucosal tissues were taken for electron microscopic examinations at the second, fourth, sixth, and tenth week after drug intervention.

RESULTSThe overlapping score was 2.10 ± 0.45 in the blank group, 5.10 ± 0.56 in the loratadine group, 5.10 ± 0.56 in the AR model group, 5.20 ± 0.78 in the GA group, showing statistical difference when compared with the blank group (P < 0.01). Results under transmission electron microscope showed that the number of the endoplasmic reticulum increased in the AR model group, with obvious cystic dilatation, a lot of vacuole formation, and degranulation. A large number of free ribosomes could be seen in cytoplasm. With persistent allergen exposure, changes mentioned above was progressively aggravated in the endoplasmic reticulum of nasal mucosal epithelium in the AR model group. But the dilation of endoplasmic reticulum, vacuole formation, and degranulation were relieved in the GA group, and got close to those of the blank group.

CONCLUSION18-β GA could improve the expansion, vacuolization, and degranulation of the endoplasmic reticulum of nasal epithelial cells in AR model rats.
