Objective To explore the influence of thyroid status on serum level of leptin and expression of leptin mRNA in rats with hypothyroidism or hyperthyroidism.Methods Fifty rats were artificially rendered hyperthyroidism and hypothyroidism by L-thyroxine or methimazole and divided into 5 groups.The serum of T 3,T 4,TSH,leptin concentration and expression of leptin mRNA were measured in 5 groups.Results Serum leptin concentration was significantly correlated with weight of rats in 5 groups(P

Objective To study the effects of calcitonin on bone mineral density(BMD), bone strength and bone fragile fracture in osteoporosis. Methods This is a one year, single centered, prospective and randomized, opening study: 135 patients with osteoporosis were divided into calcitonin+calcium group and calcium group. Patients of calcitonin+calcium group received salmon calcitonin(Miacalcic was injected intramuscularly, 50 IU/day in first week, 50 IU/two days in second week and 50 IU/twice/week later) and calcium(calcium 600 mg/day), patients in another group received calcium(calcium 600 mg/day). The determination markers included serum calcium, serum phosphate, serum alkline phosphatase, osteocalcin and urine hydroxyproline before and after treatment, at same time all patients were examined by DEXA(lumbar, hip) and QUS(radius, tibia). Results After 1 year treatment, 53 patients of calcitonin+calcium group and 59 patients of calcium group were followed up. In calcitonin+calcium group, BMD of lumbar spine increased about 1%(P

Objective To investigate the changes of serum interleukin 8(IL-8) level in children with thyroid disfunction and its clinical significance in children with autoimmune thyroid disease(AITD).Method Serum IL-8 of 30 children with hyperthyroidism,16 children with hypotyroidism and 20 health children were detected by double antibody enzyme linked immunossorbent assay(ELISA).Results Serum IL-8 levels in hyperthyroidism and hypothyroidism children were significantly higher than that in controls(P0.05).With the remission of the diseases, IL-8 levels decreased; there was a significant difference between serum IL-8 levels in patients before and after therapy (P

Although the type of XHD150B-IO 800mA X-ray machine possesses a damage protection electric circuit for the main thyristors, with the first switch of photographic hand valve pressed, abnormal instant exposure still appears when double (in different phase) or more than three main thyristors are broken through, short-circuited or mis-energized, and consequently the high voltage element or X-ray machine will break down. Therefore the original electric circuit must be improved. Material: A few of leads. Method: We exchange the conjunction sequence of three NO (normal open) contacting points of radiograph high voltage preparing work relay--MAG SW- R with three reverse parallel connection of main thyristors. Conclusion: The normal procedure of radiographic exposure won't be disturbed after the improvement. When whichever one or more than two main thyristors is broken through, short-circuited or mis-energized, the spoilage can be detected instantly and the protection circuit works correspondingly, which guarantees the safety of X-ray machine.

Objective:To compare the pain control efficiency of continuous adductor canal block (ACB) and femoral nerve block (FNB) in total knee arthroplasty.Methods:From April to September 2016,patients with severe knee osteoarthritis undergoing primary unilateral total knee arthroplasty (TKA) were prospectively observed,and all the patients were randomized received ultrasound-guided continuous ACB or FNB after surgery.Numeric pain rating scales (NPRS)pain scores in rest and activity 2,6,12,24 and 48 h after surgery were collected,and the preoperative and postoperative quadriceps strength at 24 and 48 h were analyzed.Opioids consumption and anesthesia related adverse effects were also recorded.Results:In the study,40 patients were enrolled,with 20 patients in each group,male ∶female =7 ∶ 33,the age:(63.8 ± 10.1) years,and the body mass index (BMI):(28.5 ± 3.5) kg/ m2.The general conditions were comparable between the two groups.Though the rest pain 2 h after surgery [ACB =0.0(0,6),FNB =3.0(0,5),P=0.004] and activity pain 12 h post operation [ACB =3.0(3,0),FNB =5.5(0,10),P =0.004] were lower in ACB group compared with FNB group,there was no statistical difference in the other pain checking points between the two groups.The quadriceps strength 24 h and 48 h after surgery were (85.3-± 27.6) N and (80.0 ± 30.1) N in ACB group,(69.0 ± 29.4) N and (64.4 ± 32.0) N in FNB group,both of them were declined by time.The exact data were higher in ACB group,however,there was no statistical difference between the two group by repeated measurements variance analysis(F =2.703,P =0.108).Four patients in ACB group and five in FNB acquired additional use of dolantin once (100 mg/per time) within 24 h.And among them,three patients acquired once dolantin in ACB,two in FNB,from 24 to 48 h postoperation.There were five patients who suffered nausea postoperation in ACB group,and one who reported xerostomia.Four patients in FNB had nausea with vomiting,and three experienced xerostomia.Deep vein thrombosis appeared in 2 patients in FNB group,but no one in ACB group.Conclusion:Continuous ACB is not superior in pain control after TKA compared with FNB,and the quadriceps strength could be reserved more by this method,which performed early benefits in fast rehabilitation.

ObjectiveTo analyze the clinical characteristics of inflammatory bowel disease (IBD) in neonates.MethodsFrom July 2010 to July 2015, seven neonates were diagnosed with IBD in Affiliated BaYi Children's Hospital, Clinical Medical College in Chinese People's Liberation Army General Hospital, Southern Medical University. The data regarding these neonatal cases were analyzed and compared with 45 children with IBD from literature. Thet-test andChi-square test were used for statistical analysis of the data.ResultsSix cases had ulcerative colitis, and one case had Crohn's disease, both occurred 2-20 days after birth, and were characterized by diarrhea, no increase in body weight, anemia and intermittent higher hypersensitive C-reactive protein. Compared with IBD in children, abdominal pain and abdominal mass were rarer, while anemia was more common in neonatal IBD. All fecal cultures and blood cultures in the seven cases of neonatal IBD were negative. Abdominal X-ray revealed intestinal wall thickening in four cases. Multiple ulcers were observed from the cecum to the rectum by colonoscopy. Chronic intestinal mucosal inflammation associated with acute inflammation were found on pathological examination. Six infants received treatment with 5-aminosalicylic acid (combined with glucocorticoid in four cases), and one received glucocorticoid treatment only. One infant was started on infliximab treatment from two years old. One of these seven cases died one month after discharge due to refusal to continue treatment, and the disease was controlled in the other six cases. After treatment, one infant was lost to follow-up six months after discharge, two were cured at six and 12 months old without further treatment, and three improved and continued treatment.ConclusionsIn neonates with diarrhea, anemia and no increase in body weight, especially when antibiotic treatment is ineffective, colonoscopy should be performed to facilitate early diagnosis of IBD. Standard treatments result in good outcomes.
