Objective To explore an effective method in reconstructing of burn scar contracture of the chin and neck in children. Methods The blood in the transverse cervical artery might flow reverse into the suprascapular artery and the posterior intercostals perforators through anastomic branches. An axial skin flap in the cervico-scapulo-dorsal area could be adequately supplied by this artery, and we had therefore used this flap to repair burn scar in the neck. Results 30 cases obtained satisfactory clinical results with this flap. The follow-up for two years in 18 patients showed that the neck of the patients moved about freely, and the develpment of the chin was not influenced, and the color of flaps was fine. Conclusion The blood supply of the flap is reliable and stable. So it is a very useful method in reconstructing the burn scar of the chin-neck in children.

Objective To elucidate the prevalence of vitamin D insufficiency and deficiency in chronic kidney diseases (CKD) patients and provide the evidence for treatment of these patients. Methods Clinical data of 358 inpatients with CKD from stage 1 to stage 5 were analyzed retrospectively. Level of 25 (OH)D3 in these inpatients, as well as the levels of intact parathyroid hormone (iPTH), hemoglobin (Hb), serum creatinine (Scr), urea nitrogen (BUN), carbon dioxide combining power (CO2CP), alhumin (Alb), serum calcium (Ca) and blood serum (P) were examined. Correlation between 25 (OH)D3 and parameters was analyzed. Results The mean level of 25 (OH)D3 in these CKD patients was (18.58±11.7) μg/L, which was significantly lower than that of normal reference (P<0.01). The 25(OH )D3 levels of CKD patients from stage 1 to stage 5 were (25.84±9.71) μg/L, (20.76±6.99) μg/L, (20.40±17.02) μg/L, (19.49±11.29) μg/L, and (14.16±7.98) μg/L respectively. The prevalence of vitamin D defieiency was 39.66%, and from CKD stage 1 to stage 5 was 5.00%, 17.50%, 37.21%, 42.37% and 57.14%. The prevalence of vitamin D insufficiency was 44.97%, and from CKD stage 1 to stage 5 was 72,50%, 47.50%, 45.35%, 33.90% and 40.60%. The prevalence of decreased vitamin D level was 84.63%, and from CKD stage 1 to stage 5 was 77.50%, 65.00%, 82.56%, 76.27% and 97.74%. Single factor correlation analysis showed 25 (OH)D3 was correlated with Hb, Alb, Scr, eGRF and iPTH. Regression analysis indicated that 25 (OH)D3 was negatively correlated with iPTH and Scr, and positively correlated with Alb. According to K/DOQI, percentage of CKD patients from stage 3 to stage 5 who were consistent with vitamin D treatment was 87.20%, 83.05% and 26.31% based on 25 (OH)3 and iPTH levels, but such percentage was 16.28%, 35.59% and 26.31% based on iPTH level only. Conclusions The prevalence of vitamin D insufficiency and deficiency in patients with CKD is quite high. Alia, iPTH and Scr are key factors influencing vitamin D level. Vitamin D level should be measured among CKD patients in order to carry out corresponding treatment.

Objective To study the relationship among apoptosis,NF-KB activation and uPA expres- sion in human colon carcinoma cell line HCTll6 induced by 5-fluorouracil,and to observe the effect of in- hibiting activity of NF-KB by PDTC on apoptosis as well as expression of uPA.Methods Cell apoptosis was analysed by Annexin V-FITC.Fluctuation of NF-KB and uPA was detected by semi-quantitative immuno- histochemistry.Results 5-fluorouracil could induce apoptosis and activate NF-KB.PDTC could significantly increase the apoptosis and suppress the activation of NF-KB induced by 5-fluorouracil.There was a positive correlation between the changes of uPA and NF-KB.Conclusion 5-fluorouracil could induce apoptosis,ac- tivate NF-KB and up-regulate expression of uPA of HCT116 cells.The mechanism of enhanced apoptosis by PDTC may be related to suppressing activation of NF-?B and down-regulating expression of uPA.

To investigate the effects of cembrane-type diterpenes extracted from Sinularia flexibilis on the proliferation of PC12 cells and their protective effects on PC12 cells exposed to glutamate.

The medical and health organization management information system at grass-root level and platform at county level for data exchange in Sichuan Province were designed and constructed according to the health information exchange service network in Sichuan Province and standard medical CDA file, in order to implement data exchange on the medical and health organization management information system at grass-root level and platform at county level, to insure the basic medical and health service for the public, and to improve their health level.

Objective To provide the evidence for health management decision-making and rational use of drugs grass root clinics by studying their drug prescription rules.Methods The prescribed drugs in clinics of 5 township health centers from September 2012 to September 2014 were retrieved from The Management Information System of Sichuan Grass Root Medical Institutions.Their big data were analyzed using R language.Results The commonly pre-scribed drugs in clinics were vitamin B6, vitamin C and cefixime tablets, which were usually used in combination. Conclusion Health administrative organizations can strengthen their supervision and management of prescribed drugs and promote their rational use in grass root clinics using unified management information system of grass root medical institutions in combination with information technology .

Forty-three children with congenital hypothyroidism(CH)underwent 99mTc thyroid scintigraphy, after being followed up by receiving levothyroxine till 2 to 3 years of age. The results showed that thyroid agenesia happened in 37 cases( 86.05% ) while entopic gland in 6 cases (13.95% ). Thyroid scintigraphy with 99mTc is an informative procedure in determining etiology and treatment schedules for children with CH.
