ObjectiveUsing large sample clinical study to reevaluate the safety and efficacy of recombinant human growth hormone(ANSOMONE) in treating pediatric growth hormone deficiency(GHD).Methods1012 cases were administered with ANSOMONE at a dose of 0.1 IU · kg-1 · d -1 in bedtime for 6 months.The alteration of mean height,growth rate,height standard deviation scores,bone age,and anti-GH antibody and occurrence of adverse effects were observed.ResultsThe growth rate was promoted from ( 2.50 ± 0.85 ) cm/year to ( 13.44 ± 4.27 ) cm/year,the net growth rate was( 10.94 ±3.69)cm/year.There was significant difference between the pre-treatment and post-treatment patients ( P ＜ 0.01 ).The post-treatment anti-GH antibody positive rate was 13.34％,which had no obvious effect on the efficacy.Few patients exert transient inflammation reactions,which disappeared with any treatment.ConclusionANSOMONE had significant efficacy,and could promote the height increase obviously.It had good safety without any obvious side effect and early-maturing effect.

Objective To summarize the experience and lesson of surgical treatment of acute traumatic brain injury.Methods A total of 516 cases with acute traumatic brain injury treated surgi- cally from January 2001 to December 2004 in our hospital were analyzed retrospectively.Of all,there were 56 cases with simple comminuted depressed fractures,138 with brain contusion and laceration and/ or intracerebral hematoma,122 with epidural hematoma,126 with suhdural hematoma,48 with diffuse brain swelling,18 with open brain injuries and eight with other kind of injury,all of whom were treated with standard large eraniectomy under general anaesthesia.The treatment results were evaluated by Glas- cow Outcome Scale(GOS).Results Of all,standard large craniectomy was performed in 194 cases, of which 304 cases(58.9%)were with good recovery,66(12.8%)with moderate deficit,72(13.9%) with severe deficit,12(2.3%)under persistent vegetative status and 62(12.0%)died 3-6 months after surgery.Conclusions More attention should be paid to surgery for traumatic brain injury.Individual surgical treatment should be performed under surgical principles.

[Summary] The activities of 17α-hydroxylase and 17,20 lyase of cytochrome P450c17 were evaluated by ELISA in NCI-H295R cells after treatment with palmitate and oleate. The results showed that 0. 75 mmol/L plamitate did not influence the activity of 17α-hydroxylase, but increased the activity of 17, 20 lyase by 74. 3% ( P<0. 05). Oleate at the same concentration did not change the activity of 17,20 lyase. There were no significant changes in the protein expressions of P450c17, P450 oxidoreductase, and cytochrome b5 after treatment with palmitate and oleate. However,reactive oxygen species in cells were elevated by palmitate. The results suggest that exposure to palmitate may increase androgen production by inducing 17, 20 lyase activity of P450c17 in NCI-H295R cells, which is related with oxidative stress-mediated post-translational regulation of the enzyme.

ObjectiveTo investigate the relationship between tumor necrosis factor (TNF) α308,TNF-β252 genotypes and serum TNF-α and TNF-β levels in patients with gastric cancer (GC).MethodsA total of 57 pathological diagnosed GC patients were collected,of which 49 cases were from Zhongnan Hospital of Wuhan University and 8 cases were from Tumor Hospital of Hubei Province.Another 18 age and sex matched healthy controls were enrolled at the same time.The TNF-α308 and TNF -β252 polymorphism was genotyped by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP).The serum TNF-α and TNF-β levels of 57 GC patients and 18 healthy controls were measured by ELISA.The difference of TNF serum level in different TNF genotypes of GC and the difference between GC patients and the healthy controls was analyzed.Its relationship with clinical pathological characters was also analyzed.Results With TNF-α308 genotype,GA were 6 cases and GG were 51 cases.With TNF-β252 genotype,GG were 17 cases,GA and AA each were 20 cases.The serum TNF-α level of GC patients was significant higher than that of healthy controls (median 445 × 10-3 μg/L vs 5 × 10-3 μg/L,P＜0.05),and the serum level of each TNF-α308 andTNF-β 252 genotypes was significant higher than that of healthy controls (P＜0.05).However there was no statistical significance in TNF -β level compared with healthy controls (P＞0.05).In addition,the serum TNF-α levels of the TNF-α308G/TNF-β252G and TNF-α308G/TNF β252A haplotypes in GC patients were significant higher than those of the healthy controls (P＜0.05),and the increase like serum TNF-α level was associated with the patients'age and lymph node metastasis (P＜0.05).The TNF-β level in patients with TNF-α308A and TNF-β252G high-risk haplotypes showed a significant relation with smoking history (P＜ 0.05). Conclusions Serum TNF-α level of GC patients was significantly higher,however there was no significant association between the increase and TNF-α308 and TNF-β252 genotypes.The serum TNF-α levels of TNF-α308G/TNF-β252G and TNF-α308G/TNF-β252A haplotypes in GC patients were significant higher,and associated with the patients'age and lympb node metastasis.It was indicated that TNF haplotypes may have certain impact on the TNF expression and clinical subtypes in GC.

Polyamine biosynthesis is controlled primarily by omithine Decarboxylase (ODC) and S-adenosylmethionine decarboxylase (AdoMetDC). Antisense ODC and AdoMetDC sequences were cloned into an adenoviral vector (Ad-ODC-AdoMetDCas). To study the inhibitory effects of Ad-ODC-AdoMetDCas on polyamine biosynthesis and esophageal cancer cell apoptosis, adenovirus-mediated gene tmnsduction efficiency was assessed with counting GFP-positive cells using MTT. The malignant phenotype of Eca109 cells was assessed by growth curve. Western blot and HPLC were used to detect ODC and AdoMetDC expression and polyamine content in Ecal09 cells. TUNEL was used to analyze cell apoptosis. The change of morphology of apoptotic cells was observed by electron microscope. It was demonstrated approximate 70% of Eca 109 cells were infected with Ad-ODC-AdoMetDCas when MOI reached 50. The expression of ODC was inhibited in the infected tumor cells. Ad-ODC-AdoMetDCas could inhibit Ecal09 cell growth and invasive ability. TUNEL proved that Ad-ODC-AdoMetDCas can lead to cell apoptosis. Characterized morphology was observed by electronmicroscope (ehromatincondensation,nuclear disintegration,formation of apoptoticbodies).It was suggested Ad-ODC-AdoMetDCas has significant inhibitory effects on esophageal cancer cell proliferation, leads to cell apoptosis and bears therapeutic potential for the treatment of esophageal cancer.

OBJECTIVETo investigate the factors influencing the pregnancy outcomes of artificial insemination with donor sperm (AID), improve the pregnancy rate, and evaluate the safety of the offspring.

METHODSWe retrospectively analyzed 7,761 cycles of AID for 5,109 infertile couples performed between July 1, 2005 and June 30, 2013 in the Center of Reproductive Medicine of Shenyang No 204 Hospital, the outcomes of pregnancy, and the incidence of birth defects.

RESULTSTotally, 2 252 clinical pregnancies were achieved by AID, in which the pregnancy rate per cycle was 29. 02% and the cumulative pregnancy rate was 44. 08%. The clinical pregnancy rate was remarkably higher in the females of ≤ 35 years than in those of > 35 years old (30.31% vs 20.18%, P < 0.01), in the women with < 5-year infertility than in those with > 5-year infertility (30.83% vs 28.16%, P < 0.01), and in the patients of the ovarian stimulation group than in those of the natural cycle group (33.22% vs 28.68%, P < 0.01) The clinical pregnancy rate was the highest in the first treatment cycle (29.87%), with statistically significant difference from the fourth cycle (23.61%) (P < 0.05), but not between the other cycles (P > 0.05). There were 28 cases of birth defects in the offspring (1.40%), including 6 cases (21.43%) involving the cardiovascular system, 4 (14.29%) involving the musculoskeletal system, 3 (10.71%) involving the urogenital system, 3 (10.71%) involving the central nervous system, 2 cases (7.14%) of cleft lip and palate, 2 (7.14%) involving the respiratory system, 2 (7.14%) involving the gastrointestinal digestive system, and other anomalies.

CONCLUSIONFemale age, infertility duration, and ovarian stimulation treatment are important factors influencing the clinical pregnancy rate of AID. Artificial insemination with cryopreserved donor sperm does not increase the incidence of birth defects, which is considered as a relatively safe technique of assisted reproduction.
