Objective To assess the quality of iodized salt and investigate the urinary iodine level of pupils and women after implementation of universal salt iodization in Shijiazhuang city. Methods Between 2004 and 2008, nine salt samples were randomly collected from wholesale enterprises of 5 different directions of east,south, west, north and center in Shijiazhuang city every month. Meanwhile, eight salt samples, four urine samples of women, were randomly collected in each of the 8 households of 210 villages selected from 23 counties. Between 2004 and 2008, twenty urine samples of 8 - 10 year old pupils were collected in each of 160 schools from the 23 counties. Direct titration method was used for salt iodine determination, iodine concentration in urine was detected by the method of ammonium persulfate digestion-As3+-Ce4 + catalytic spectrophotometry. Results At wholesale level, the qualified rate of iodized salt was above 99%. At household level, the consuming rate of iodized salt was above 95%, and the rate of consuming non-iodized salt was less than 5%. The rate of qualified iodized salt was above 90% in every year except 2004(87.10%), and the rate of consuming qualified iodized salt was above 90% in those years except 2004(83.08%). Urinary median iodine level of both the pupils and the women was higher than 100 μg/L, and the rate of urinary iodine level that less than 50 μg/L was below 10%. Conclusions The quality assessment of iodized salt from wholesale companies and related indices of urinary iodine level of pupils, women and household iodized salt have already reached the national standard for eliminating iodine deficiency disorders.

The morbidity of diabetes has been increasing rapidly in recent years. Delayed wound healing has become a common complication in diabetes, which seriously affects the orthobiosis of patients. Exploring and finding the molecular mechanisms of diabetic wound healing and the effective therapies to promote wound healing have important clinical significances. Stem cells transplant has become a research hotspot in accelerating diabetic wound healing. This article reviewed the present approaches concerning stem cells transplant in diabetic wound healing both at domestic and abroad, and looked forward the clinical therapy of stem cells on diabetic wound healing.

Objective To investigate the oxalate-degrading and growth abilities of lactic acid bacteria coming from yoghourt in vitro culture broth. Methods The species of lactic acid bacteria obtained from 6 brands of yoghourt were identified. Different brands of yoghourt were separately cultured in broth and incubated at 37 ℃,5% CO2 for 48 h, getting the concentration of lactic acid bacteria through slab counting method. The brand of yoghourt with the highest quantity of bacteria was chosen as the study subject. Three species of bacteria and the mixture bacteria obtained from the chosen brand of yoghourt were cultured separately for 72 h in MRS broth which contained three different concentrations of ammonium oxalate, and the broth without inoculating of bacterium was prepared as control. The amount of bacteria in culture was detected, the concentration of ammonium oxalate was detected through photometric determination of oxalic acid by its catalytic reaction of methyl red by potassium chromate. Results Three species of lactic acid bacteria (L.bulgaria, L.acidophilus and L.thermophilus) were detected in each brand of yoghourt. The quantity of bacteria in Weiquan yoghourt is the highest. After 72 h incubation, the concentrations of oxalate in all the broths containing bacteria were lower than those in the control. L.acidophilus showed the best degrading activity. The higher the concentration of oxalate was, the bigger the amount of oxalate degraded was, the smaller the percent of degrading was, and the less the growth ability of bacteria was. Conclusion All the species coming from yoghourt have the ability of oxalate degrading, which increases with the concentration of oxalate in culture.But the high concentration of oxalate restrains the growth of bacteria.

Objective To compare the treatment effect of autologous blister skin grafting with ReCell autologous chromocyte grafting on cicatricial depigmentation caused by deep burn.Methods Thirty-four patients with cicatricial depigmentation caused by deep burn who were admitted into hospital from May 2012 to February 2015 were included in this study.The total 61 depigmentation areas were randomly divided into two groups;32 areas from 18 patients were treated with autologous blister skin grafting,and the other 29 areas from 16 patients were trea-ted with ReCell autologous chromocyte grafting.In the autologous blister skin grafting treated group,epidermis from the depigmentation area was removed by grinding with a BY-II AM type epidermal graft vitiligo treatment equipment.Then the autologous blister skin was harvested with the suction blistering method and grafted onto the wound of depigmentation area.In the ReCell autologous chromocyte grafting treated group,split-thickness skin flap was harvested by electric dermatome.Then the donor skin was processed into chromocyte suspension with the ReCell assay kit and evenly sprayed onto the depigmentation areas.The wound healing time and the pigment recovery 3 months after surgery were observed.Results The wound healing time of autologous blister skin grafting treated group was significantly shorter than that of ReCell autologous chromocyte grafting treated group (P <0.05 ).The effective rate of pigment recovery 3 months after surgery in autologous blister skin grafting treated group was markedly higher than that of ReCell autologous chromocyte grafting treated group(P <0.05 ). Conclusion The autologous epidermal grafting treatment using grinding and suction blistering method is simple and easy to perform,marked-ly effective,with no suture scar and low surgical risk,thus serving as a promising and ideal therapeutic method for burn scar depigmentation.

OBJECTIVE Inflammatory myofibroblastic tumor(IMT) is a rare lesion of unknown etiology which was first described in the lung. The clinical and pathologic characteristics,treatment, prognosis of IMT in head and neck were discussed. METHODS The clinical data of 4 cases of IMT were analyzed retrospectively. The specimens of the 4 cases were prepared for immunohistochemical staining and light microscopy. RESULTS The patients included 3 males and 1 female. Their age ranged from 32 to 58 years. The tumors located at the true vocal cord in 2 cases, at the nasal cavity and maxillary sinus in 1 case, at the maxillary sinus in 1 case. Histological examination was found that the tumors consisted of spindle cells,chronic inflammatory cells and myxoid background with delicate vasculature. Immunohistochemical staining demonstrated that the SMActin and Vimentin were expressed positively in the tumor. The patients were followed up for 9 to 21 months after operation. Three patients were alive with no evidence of diseases, one patients recurred at 4 months after operation and were alive with IMT. CONCLUSION IMT is a true neoplasm with a potential of local recurrence. The main treatment of IMT is to resect the lesions thoroughly.

Objective To evaluate the pattern of energy metabolism and nutrients intake in patients with chronic viral hepatitis and posthepatitic cirrhosis to effectively direct their nutrition therapy.Methods Resting energy expenditure (REE) was measured with open-circuit indirect Jorimetry in 60 patients with chronic viral hepatitis and 60 patients with posthepatitic cirrhosis.Their normal basal energy expenditure (BEE) was predicted by Harris-Benedict equation and energy intake (EI) was determined by diet recall. Correlation between REE and indicators for nutrition assessment was analyzed.Results REE was (77? 21) kJ?kg~(-1)?d~(-1) in 60 patients with pusthepatitic cirrhosis,significantly lower than BEE[(95?16) kJ? kg~(-1)?d~(-1)(P0.05,and their EI was (127?34) kJ?kg~(-1)?d~(-1),1.41?0.43 times as REE,in which PROI was (1.02?0.29) g?kg~(-1)?d~(-1),1.31?0.61 times as PROE (0.87?0.34) g?kg~(-1)?d~(-1),also indicating a negative nitrogen balance (-2.02?4.07).REE,EI and intake of three nutrients,serum level of albumin and prealbumin (PA) and body weight significantly decreased in patients with posthepatitic cirrhosis,as compared to those in patients with chronic viral hepatitis (P
