Objective To discuss the prevention and treatment for complications following laparoscopic cholecystectomy (LC). Methods A total of 902 cases were summarized retrospectively with regard to causes, prevention and treatment of complications following LC. Results Out of the 902 cases, there were 2 cases of bile duct injury, 2 cases of residual calculi of common bile duct, and 4 cases of scrotum emphysema. The bile duct injury and residual calculi were all cured by re-operation, while the scrotum emphysema dissolved of itself without medical treatment. A conversion to open surgery was required in 31 cases. All the cases in the study were cured. Conclusions Emphasis should be laid on the prevention of complications after LC. A prompt conversion to open cholecystectomy is the key to the lowering of complication rate.

AIM: To analyze the effect of human amniotic homogenate extract on corneal neovascularization after corneal alkali burn in the process of pigment epithelium derived factor (PEDF) and vascular endothelial growth factor (VEGF) expression and the effect of corneal neovascularization.METHODS: Totally 32 patients with corneal alkali burn were selected from June 2015 to June 2016 in Foshan,and were randomly divided into Group A and Group B,with a total of 37 eyes.Group A of 17 cases,with a total of 19 eyes,were treated with 40mg/L human amniotic homogenate extract;Group B (n=15),and 18 eyes,treated with 3g/L prednisolone eye drops.In the treatment of 1,4,7,14,21 and 28d at different time points,we observed the growth of corneal neovascularization,and detected the expression of PEDF and VEGF during angiogenesis.RESULTS: Group A of patients in the use of human amniotic homogenate extract after the treatment,the expression level of PEDF was significantly higher than that in Group B(P=0.001),after 28d treatment,the expression level of PEDF reached 0.721±0.314.While patients in Group B the expression level of PEDF was only 0.538±0.253.Two groups had significant difference between the expression level of PEDF (P<0.05).The expression level of VEGF in Group A was lower than in Group B at different time points in the test.After the treatment of 28d patients in the Group A,the expression level of VEGF was 0.152±0.020,in Group B the expression level of VEGF was0.302±0.031.Two groups of patients with VEGF expression level between the differences were statistically significant (P<0.05).The patients number in Group A with corneal neovascularization was significantly lower than that in Group B,the difference was statistically significant (P<0.05).CONCLUSION: Human amniotic homogenate extract can increase the expression of PEDF in corneal neovascularization after corneal alkali burn,inhibit the expression of VEGF and the proliferation of corneal neovascularization.

Objective To summary the clinical data of pediatric renal transplantation from multiple renal transplant centers in China,and analyze the factors influencing the therapeutic outcomes of pediatric renal transplantation.Methods From March 1986 to May 2010,the clinical data of 138 children who underwent renal transplantation in eight centers of renal transplantation in China were retrospectively analyzed.Results The one-year patient and graft survival rate was 99.3% and 95.7%respectively.Acute rejection episodes occurred in 38 cases (27.5%),15 cases suffered delayed graft function (DGF),and graft functions were returned to normal in all recipients within one month.Moreover,other complications included transplant renal artery stenosis in 8 cases (5.8%),ureteral necrosis in 2 cases (1.4%),urinary fistula in 5 cases (3.6%),hypertension in 57 cases (41.3 %),hyperlipidemia in 38 cases (27.5%),hirsutism in 32 cases (23.2%),drug-induced liver damage in 26 cases (18.8%),urinary tract infection in 25 cases (18.1% ),gingival hyperplasia in 22 cases (15.9%),pulmonary infection in 21 cases (15.2%),bone marrow suppression in 12 patients (8.7%),herpes simplex in 10 cases (7.2%),and diabetes in 8 cases (5.8%).The body weight was increased by 4 to 13 kg and the body height was increased by 2 to 7 cm during the first year posttransplantation. Conclusion The careful perioperative management, rational use of immunosuppressive agents,strengthening the follow-up management of children and social support,and improving compliance were the key points to obtain good outcomes in pediatric renal transplantation.

OBJECTIVE:To compare in vivo and in vitro permeation behaviors of the ethosome gels of testosterone,testoster-one propionate and testosterone undecanoate. METHODS:The ethosome gels of testosterone,testosterone propionate and testoster-one undecanoate were prepared. With cumulative permeating amount and permeation rate as the indexes,Franz diffusion cell and HPLC were employed to compare in vitro permeation behaviors of 3 kinds of ethosome gels in mouse skin. With testosterone patch as the positive control drug, electrochemistry method was adopted to detect the concentration of testosterone in plasma 0,3,6, 9,12,24,36 and 48 h after applying such 3 kinds of ethosome gels on the back of rats,and then pharmacokinetic parameters were calculated with DAS 2.0 software. RESULTS:24 h cumulative permeating amounts of the ethosome gels of testosterone,tes-tosterone propionate and testosterone undecanoate were(234.31±13.8),(175.63±41.1)and(72.60±15.3)μg/cm2,and the per-meation rates were(10.25±1.9),(7.64±1.4)and(2.96±0.8)μg/(cm2·h),respectively. The pharmacokinetic parameters of the above-mentioned three kinds of ethosome gels and the positive control drug were respectively as follows as cmax of(20.19±2.57), (17.50±2.91),(0.23±0.04),(14.97±2.12)ng/ml,t1/2Ka of(2.80±0.45),(3.36±0.59),(4.02±0.62),(4.20±0.71)h,AUC0-48 h of(13.85±1.96),(13.93±2.13),(0.35±0.07),(11.76±2.31)ng·h/ml. CONCLUSIONS:in vivo and in vitro permeation behav-iors of the ethosome gels of testosterone and testosterone propionate are fairly good.

Objective To investigate and evaluate the iodine nutritional status of school-age children in Yi county of Heibei Province,and to provide scientific basis for the development of control measures to iodine deficiency disorders.Methods Retrospectinely analyzed school-age children urinary iodine monitoring results of Yi County of Hebei Province from 1998 to 2011.One township was selected randomly in each of the five directions (east,west,south,north and center) from 1998 to 2011.One elementary school was randomly chosen in each of the five townships.And at least 20 urine samples of 8-10 years old children were randomly collected in each school selected.Urinary iodine contents were determined through arsenic cerium catalytic spectrophotometric method.Urinary iodine determination standard according to The Standard of Iodine Deficiency Disorders Elinination (GB 16006-2008) and The Iodine Deficiency Disorders Elinination Guide.Results A total of 1725 children urinary samples were collected from 1998 to 2011,urinary median was 243.26 μg/L,each of the median urinary iodine was higher than 100 μg/L.The ratio of urinary iodine less than 100 μg/L was < 50% over the years,and less than 50 μg/L was < 20%.Overall,the highest value of urinary iodine stayed at approximately 200 μg/L,showing positively skewed distribution that was skewed to the right.Urinary iodine level was compared among different ages,gender and ethnicity,and the difference was not statistically significant(P > 0.05).Conclusions In recent years,the iodine intake of school-age children of Yi County can meet the body needs,and the iodine nutrition is at an appropriate level.

After testing the resistance of streptomycin to NS-41-80 Streptomyces Nanchangensis NS-41-80, the spores treated with 4 different dosage of super-mutagent EMS were regenerated on the lethal media, thus 3,000 streptomycin-resistant ( str ) str mutants were obtained. Then 202 spore mutants were screened through the pre-screening experiments and their yields are beyond 20% higher than the original strains respectively. In the re-screening experiments 48, 7 and 1 mutants were obtained whose yields are 100%, 200% and 300% higher than the original strains respectively and take the precentage of 23.76% and 1.60%, 3.46% and 0.23% and 0.5% and 0.03% of the number of the pre-screened strains and the rescreened strains respectively. Then 5 mutants were fermented whose yields are above 240% higher and the original strain through the continuous 3 batches fermentation, the yields are 57%~96.4% more than the original strains. Among them the yield of 80-5.3-165 is upwards of 6,000?g/mL and its norm is 5,855?g/mL. And a model of the streptomycin-resistance mutational screening of the strain producing Nanchangmycin was established.
