Objective:To observe the clinical efficacy of combined acupuncture and scraping therapy for simple obesity and its effects on phlegm-dampness constitution.Methods:Seventy subjects with phlegm-dampness constitution were divided into treatment group and control group with a randomized digital table.Control group was given health education and dietary instructions,and treatment group was given acupuncture and scraping therapy besides health education and dietary instructions.After four-week treatments,the scores of obesity and phlegm-dampness constitution were recorded to assess the clinical efficacy.Results:There was a striking difierence in the total effective rate in treating obesity between the two groups (P＜0.01);combined acupuncture and scraping therapy can relieve the phlegm-dampness symptoms(P＜0.01);but the phlegm-dampness symptoms were not improved in the control group(P＞0.05).Conclusion:Combined acupuncture and scraping therapy is quite effective for simple obesity and in improving phlegm-dampness constitution of simple obesity people.

Objective:To observe the effect of Tangshenning on renal function and LOX-1 mRNA expression in the kidney of early diabetic nephropathy rats model. Methods:Early diabetic nephropathy rats model was made with high fat diet, STZ and unilateral ne-phregtomy. After the 12-week drug intervention, the rats were sacrificed, the kidneys were removed and the mRNA expressions of LOX-1 in the kidney were observed by the method of RT-PCR. Results:Early diabetic nephropathy rats model was successfully made by the triple-modeling method. The mRNA expression of LOX-1 in the kidney was significantly increased, and Tangshenning could low-er the expression of LOX-1 in the kidney in a dose-dependent manner. Conclusion:The abnormal expression of LOX-1 could be one of the mechanisms for diabetic nephropathy. Tangshening has good kidney protective effect through decreasing LOX-1 abnormal expression in the kidneys, which deserves further research.

Objective To evaluate the value of Multi-slice spiral CT angiography for spinal cord vessels.Methods 11 adult subjects with suspected of myelopathy were performed with Multi-slice spiral CT angiography,An iodine contrast agent was injected at 3.5 ml/s,for total 100 ml.The parameters were axial 16 slice mode,0.625 mm slice thickness,0.8 s rotation,delay time depending on smartprep (15—25 s), multi-phase scan.The coronal and sagittal MPR and SSD were generated on a workstation compared with spinal digital subtraction angiography (DSA) to analyze normal or abnormal spinal cord vessels.Results Normal findings at spinal CTA and digital subtraction angiography in six adult normal subjects and spinal cord vascular malformations( 1 intradural extramedullary AVF,4 dural AVFs) in five cases,Recognizable intradural vessels corresponding to anterior median (midline) veins and/or anterior spinal arteries were show in six adult normal subjects.Abnormal intradural vessels were detected in all five spinal cord vascular malformation with CT angiography ,in comparison with digital subtraction angiography these vessels were primarily enlarged veins of the coronal venous plexus on the cord surface,radiculomedullary-dural arteries could not be clearly shown in four dural AVF,only one anterior spinal artery was detected in one patient with intradural medullary AVF,which direct shunt between anterior spinal artery and perimedullary vein with tortuous draining vessel.Conclusion Multi-slice CT angiography is able to visualize the normal or abnormal spinal cord vessels.It could be used as a noninvasive method to screen the spinal cord vascular disease.

AIM:To conduct the relevance analysis of serum Dickkopf-1 (Dkk-1) and bone mineral density (BMD) in the different ages of female populations.METHODS: The women volunteers (n=100, 20~80 years old) were selected and divided into young group (20~39 years old), middle age group (40~59 years old) and elderly group (60~80 years old).The serum levels of Dkk-1 in the 3 groups of volunteers were detected by ELISA.In the middle age group, 25 people of 45~55 years old were selected and divided into postmenopausal group and premenopausal group to de-tect the serum level of Dkk-1 in the 2 groups of volunteers by ELISA.The BMD was measured by the method of dual energy X-ray absorptiometry.The differences of Dkk-1 expression levels among different ages of female populations, and the rele-vance with BMD were compared.RESULTS:With the increase in age, the serum Dkk-1 expression level increased ( P<0.05), and BMD were reduced (P<0.05).The blood level of Dkk-1 and BMD negatively correlated (P<0.05) in the 3 groups of volunteers.The serum levels of Dkk-1 and BMD had stronger negative correlation in postmenopausal women group than that in premenopausal women group.CONCLUSION:With the increase in age, the expression level of serum Dkk-1 increases and the BMD level decreases, which contribute to a risk of osteoporosis.In the same age range, the postmeno-pausal women express higher level of Dkk-1, and the decreased BMD is more obvious, which contribute to a greater risk of osteoporosis.The increased level of Dkk-1 also inhibits bone formation and promotes bone resorption.It may become a new target for preventing and treating osteoporosis.

Objective To evaluate the effect of dexmedetomidine on acute kidney injury after cardiac valve replacement with cardiopulmonary bypass (CPB).Methods One hundred patients of both sexes with rheumatic heart disease,aged 32-64 yr,weighing 46-75 kg,of American Society of Anesthesiologists physical status Ⅱ or Ⅲ (New York Heart Association class Ⅱ or Ⅲ),scheduled for elective cardiac valve replacement with CPB,were divided into 2 groups (n =50 each) using a random number table:control group (group C) and dexmedetomidine group (group D).Dexmedetomidine was intravenously infused in a loading dose of 1 μg/kg over 10 min before induction of anesthesia followed by an infusion of 0.4 μg · kg-1 · h-1 until 24 h after operation in group D,while the equal volume of normal saline was given in group C.The urine output per hour during the postoperative 48 h period was recorded.At 6,12,24,36 and 48 h after operation,blood samples were collected from the median cubital vein for determination of serum creatinine levels.The development and severity of acute kidney injury were determined according to the urine output and serum creatinine level.Results Compared with group C,the incidence and severity of acute kidney injury were significantly decreased in the postoperative 48 h period in group D (P＜0.05).Conclusion Dexmedetomidine infused in a loading dose of 1 μg/kg over 10 min before induction of anesthesia followed by an infusion of 0.4 μg · kg-1 · h-1 until 24 h after operation can reduce the development and severity of acute kidney injury after cardiac valve replacement with CPB in patients.
