Objective:To explore the role of Th17 cells in the pathogenesis with Graves′disease (GD),through examining the proportion of peripheral of Th17 cells and the plasma levels of Interleukin-17 ( IL-17 ) before and after 131 I or methimazol ( MMI ) treatment with GD patients.Methods:We studied 31 subjects and 30 subjects with GD after 131 I or MMI treatment as 131 I therapy group and MMI therapy group and examined as before treatment (T0 ),one month (T1)and three months (T3)after the treatment.29 age-and sexmatched healthy subjects were enrolled as the healthy control group.The Th17 lymphocytes cells were investigated by flow cytometry analysis.The levels of serum IL-17 were measured by ELISA.Results:The proportion of peripheral Th17 cells and the levels of IL-17 were significantly increased in the T0 group GD patients compared with the control group( P<0.01).In the 131 I therapy group the levels of Th17 cells,IL-17 in T0,T1,T3 decreased gradually,but still higher than in normal group( P<0.01) .But there was no sig-nificant difference in MMI therapy group (P>0.05).The proportion of peripheral Th17 cells had positive relationship with the level of IL-17( r=0.758,P<0.05 ) .Both of them were associated positively with thyroid autoantibodies.Conclusion: Th17 cells, IL-17 are highly expressed in the GD.Th17 cells may play an important role in the pathogenesis of GD.In addition,radioactive 131 I may also work on GD via Th17 cells and IL-17.

Objective:To establish a fluid dynamics model of upper airway before and after surgery and explore the changes of three-dimensional fluid dynamics in patients with micrognathia.Methods:A patient with micrognathia and severe obstructive sleep apnea-hypopnea syndrome(OSAHS)accepted CT scan before and six months after mandibular advancement operation.Computation-al fluid dynamics model was built on the base of CT scan by Mimics 1 0.01 and ANSYS ICEMCFD1 4.0.The internal flow of upper respiratory tract was simulated by ANSYS-FLUENT 1 4.0 and the results were analyzed by Tecplot.Results:Fluid dynamics model of upper airway was constructed before and after the surgery respectively.The volume of the upper airway of the patient increased from 37.284 cm3 to 44.498 cm3;the most narrow area of upper airway was located in the lower bound of pharyngopalatiae,and it was augmented from 1 .1 35 cm2 to 2.297 cm2;the minimum pressure was decreased from1 01 308 Pa to 1 01 272 Pa;the maximum air velocity increased from 3.476 m/s to 4.978 m/s.Conclusion:Mandibular advancement may correct the occlusal deformity,ex-panse the upper respiratory tract,decrease the negative pressure and maintain the patency of the airflow in the treatment of patients with micrognathia and OSAHS.

OBJECTIVETo explore the incidence, degree, and pattern of rib cartilage calcification in congenital microtia patients, in order to provide reference for harvesting the rib cartilage, sculpturing cartilage framework.

METHODSFrom Jun. 2013 to Nov. 2014, 383 patients (age range, 6-45 years) underwent CT scans of the chest. 11 patients with bony diseases or traumatic history were excluded. The remaining 372 patients were divided by age into four groups as 6-15, 16-25, 26-35, 36-45 years old. Twenty patients (10 male and 10 female) were selected by the order of patient identification number in each age group, thus selecting a total of 80 patients (40 male and 40 female). Retrospective study of CT scans of the chest in 80 patients and the incidence, degree, and pattern of cartilage calcification of the sixth to eighth ribs were noted. A chi-square test is conducted to test whether there are significant difference between the variables through the SPSS 19.0 software.

RESULTSOverall, 40.4% (194/480) cartilage was calcified; female patients (47.50%, 114/240) showed higher frequency of calcification than male patients (33.33%, 80/240, P = 0. 025). Calcification rates of all age groups are 1.7% (2/120), 46.7% (56/ 120), 49.2% (59/120), 64.2% (77/120). Calcification rate of 6-15 years group is lowest in all groups (P < 0.05) while other three groups have no statistical significance (P > 0.05). Calcification rates of the sixth and sevent rib cartilage were higher than those of the eighth rib cartilage in all age groups except 6-15 years group, who had a similar rate of all three ribs. Calcification rate of all three rib cartilage was significantly increased with age. Calcification rates of the amle's rib cartilage and the female's in all age groups are 3.3% (2/60) and 0.0% (0/60) (6-15 years): 33.3% (20/60) and 60.0% (36/60) (16-25 years): 40.0% (24/60) and 58.3% (35/60) (26-35 years), 56.7% (34/60) and 71.2% (43/60) (36-45 years). In 6-15 years group calcification rates of male and female had a similar rate, while female's rates were higher than male's rates in other three groups. Male and females mainly had the granular type of calcification [70.0% (56/80), 63.2% (72/114)].

CONCLUSIONSFemales who are over 16 years old should pay more attention to the possibility of middle-severe calcification before harvesting rib cartilage. These patients should take CT examination if necessary. In addition, the patients who had previous operation, or traumatic history, rib deformity, or spine deformity should select the CT examination.

Objective: To investigate the protecting and regulatory effects of water extract from Fructus Ligustri Lucidi (FLL) on bone structure and bone metabolism in osteoporosis rats. Methods: SD female rats were bilaterally ovariectomized to establish osteoporosis model, and Sham operated rats only cut the fat around the ovary. Experimental rats were divided into four groups: Sham operation (SHAM) group, model (OVX) group, alendronic acid sodium (ALN) group, and Fructus Ligustri Lucidi (FLL) group, with nine rats in each group. The rats in FLL group were given FLL water extract (3.5 g/kg) and rats in ALL group were given ALN suspension (0.12 g/kg) by ig administration for 12 weeks. At the end of the experiments, the contents of serum and urine calcium (S-Ca) and phosphorus (S-P), urine creatinine (U-Ca/Cr and U-P/Cr), serum high density lipoprotein (HDL-C) cholesterol, low density lipoprotein (LDL-C) cholesterol, total cholesterol (TC), and triglyceride (TG) were measured by biochemical methods. The levels of collagen I amino terminal peptide (PINP), collagen I carboxyl terminal peptide (CTX-I), osteocalcin (OCN), and urine deoxypyridinoline (DPD) were measured with ELISA. The determination of alkaline phosphatase (ALP) was by radioimmunoassay method. To evaluate the change of bone tissue structure, the bone density instrument, VivaCT, and a universal testing machine were used. Results: FLL could inhibit the increased body weight of ovariectomy (OVX) rats, increase S-Ca, S-P, serum HDL and PINP contents, reduce urinary U-Ca/Cr and U-P/Cr ratios, reduce serum LDL-C, TC, TG, ALP, OCN, CTX, and reduce urinary DPD content (P < 0.05 or 0.01) in OVX rats. Meanwhile, FLL can elevate the femur head and vertebral bone mineral density, bone micro-structure and bone strength in OVX rats. Conclusion: FLL can improve the bone density and bone strength in OVX rats by regulating Ca and P metabolism, collagen and non-collagen metabolism.

BACKGROUND:Recent studies have shown that anemia after renal transplantation is an important risk factor for cardiovascular disease after transplantation, as wel as the independent predictor of death. OBJECTIVE:To explore the prevalence, processing and risk factors of anemia after renal transplantation. METHODS:The data of 154 cases renal transplantation recipients who fol owed-up in the Department of Urology, Fuzhou General Hospital of Nanjing Military Command were retrospectively analyzed. The blood routine and blood biochemistry of the renal transplantation patients were col ected for analysis during hospitalization and 1, 2, 3, 4 and 5 years after transplantation. RESULTS AND CONCLUSION:The prevalence of anemia during transplantation and the subsequent 5 years after transplantation were 45.5%, 10.7%, 9.6%, 14.8%, 13.5%and 19.6%, respectively. Patients had anemia at least once in five years, and 42%of the patients experienced recurrence. Relative analysis showed that hemoglobin levels were associated with function of transplanted kidney. Different genders, ages and the using of angiotensin-converting enzyme inhibitors or angiotensin receptor blockers or not has no correlation with the prevalence of anemia. Binary Logistic regression analysis showed that serum creatinine and blood urea nitrogen levels at 1 year after transplantation were correlated with the diagnosis of anemia, and only associated with serum creatinine level at 5 years after transplantation. Iron drug is relatively common, but erythropoietin is rarely applied in the anemia patients with transplant renal insufficiency. The prevalence of anemia after renal transplantation is high, and transplant renal insufficiency is a major risk factor for the disease.
