Objective To investigate the effect of recombinant human growth hormone on serum levels of insulin like growth factor 1(IGF-1) and insulin-like growth factor binding protein 3(IGFBP-3)in children with short stature.Methods 48 children were diagnosed with idiopathic short stature were collected.All children were randomly divided into control group and experimental group ,24 cases in each group.Children in control group received nutritional therapy, children in experimental group were given recombinant human growth hormone on the basis of control group treatment, both group were treated for 12 month.After the treatment, the serum levels of IGF-1,IGFBP-3 and the height were detected in all children.Results Compared with control group post-treatment,,the serum level of IGF-1 was higher in experimental group ( P<0.05 );the serum level of IGFBP-3 was higher in experimental group ( P<0.05 );the height was higher in experimental group ( P<0.05 ) .Conclusion Recombinant human growth hormone can significantly increase the serum levels of IGF-1 and IGFBP-3 in children with idiopathic short stature, promote children growth, and have a guiding significance for clinical.

A novel PCR-based mutagenesis method was reported, in which there is no need to purify megaprimers or design a special flanking primer. This method used one mutagenic primer and two sequencing primers (T_m≤58℃) as flanking primers. After first round PCR, 12.5 μl first PCR production was directly added into 50 μl second PCR system as template and megaprimer, and 10 rounds of asymmetrical PCR at high temperature of annealing (68 ℃ ) was to add in initiation of second PCR. This additional step greatly has increased the efficiency of mutagenesis via 600 bp or 800 bp long megaprimer. The results demonstrated that this method can achieve high fidelity, 97%～ 98% efficiency, high yield.

Juvenile granulose cell tumor is one of the rare sex cord stromal tumors of the ovary.This review summarizes the new progress in the genetic studies of the disease.

Objective To study the effect of 3,4-oxo-isopropylidene-shikimic acid (ISA) on transcription factor STAT1, STAT3 and NF-?B in human cervix cancer Hela cell. Methods The cell proliferation was assessed by MTT assay. The luciferase activity of transcription factor STAT1, STAT3 and NF-?B was determined by the Dual-Luciferase Reporter Assay System. Results ISA can not inhibited the growth of Hela cell. The luciferase activity of transcription factor NF-?B in Hela cells treated with ISA was inhibited, while the luciferase activities of transcription factor STAT1 and STAT3 were not inhibited. Conclusion ISA can inhibit inflammation, which may be related with suppression of NF-?B transcriptional activity.

In this paper an expert system for remote fault diagnosis in the ship lift was developed by analysis of the fault tree and combination with VPN. The fault tree was constructed based on the operation condition of the ship lift. The diagnosis model was constructed by hierarchical classification of the fault tree structure, and the inference mechanism was given. Logical structure of the fault diagnosis in the ship lift was proposed. The implementation of the expert system for remote fault diagnosis in the ship lift was discussed, and the expert system developed was realized on the VPN virtual network. The system was applied to the Gaobaozhou ship lift project, and it ran successfully.

Objective To study the clinical features,diagnosis and management of small cell carcinoma of the bladder (SCCB).Method The clinical data of 18 cases of patients with small cell carcinoma of the bladder were analyzed retrospectively and the literature were reviewed.There were 16 males and 2 females,ages 54 to 81 years (median age,61 years).Clinical manifestations included gross hematuria in 11 cases,urgency in 2 cases,dysuria in 2 cases and postoperative review after TURBT of bladder urothelial carcinoma in 3 cases.The median tumor size was 3.35cm (ranged,1.0 to 6.0 cm).2 cases underwent TURBT and intravesical chemotherapy regularly were followed after surgery.3 cases underwent partial cystectomy,intravenous chemotherapy combined with radiotherapy was followed in one case,the other 2 cases refused the following therapy.13 cases underwent radical cystectomy,intravenous chemotherapy was followed in 2 cases,pelvic radiotherapy was followed in 2 csaes and intravenous chemotherapy combined with radiotherapy was followed in 2 cases,the other 7 cases refused the following therapy.Results 11 cases were pure SCCB,7 cases were mixed SCCB,all with urothelial carcinoma.T1N0M0 in 3 cases,T2N0.1M0 in 4 cases,and T3N0-2M0 in 11 cases.The duration of follow-up was from 5 to 35 months after surgery.9 cases died of tumor metastasis,9 cases are still alive,except 1 case with lymph node metastasis,the other 7 cases are free of tumor recurrence or metastasis.Conclusions SCCB is rare,with high malignant degree and poor prognosis.The prognosis of the pure SCCB may be worse than the mixed SCCB.The diagnosis depends on pathology examination.Radical cystectomy is the main treatment method,the strategy of bladder-preserving may be an attempt for proper SCCB patients.Adjuvant therapy plus surgery may be better.

Objective To compare the impact of propofol and sevoflurane on thermoregulation in children undergoing orheopaedic surgery.Methods Sixty-eight children scheduled to undergo ortho-paedic surgery were randomly allocated to receive propofol (group P)and sevoflurane(group S)anes-thesia,34 cases in each group.Tympanic temperature was recorded 5 minutes before (T0 )and 5 min (T1 ),1 5 min (T2 ),30 min (T3 ),45 min (T4 ),60 min (T5 ),75 min (T6 ),90 min (T7 ),105 min (T8 )and 120 min (T9 )after anesthesia.Total fluid intake,duration of surgery,duration of anesthe-sia,the incidence of hypothermia,and the incidence of shivering were also recorded.Results Com-pared with T0 ,in both groups body temperature declined at T1-T8 .There was no difference between the two groups in total fluid intake,duration of surgery,duration of anesthesia and the incidence of shivering.Compared with group P,children in group S had a higher incidence of hypothermia(8 vs 1). Children in group S had lower temperature,which had statistical significance at T7 and T8 (P <0.05). Conclusion The core temperature of children undergoing orthopaedic surgery showed a trend of in-crease after the first fall in the surgery.Compared with propofol,sevoflurane anesthesia is more likely to lead to the incidence of hypothermia in children undergoing orthopaedic surgery in 90 min after in-duction of anesthesia.

Objective To explore the morphological, immunohistochemical characters and prognosis in one case of patients with cutaneous anaplastic large cell lymphoma complicated with acute myeloid leukemia (C-ALCL-AML). Methods The histopathology, immunohistochemical markers and follow-up information of one case of ALCL-AML was analyzed and the correlated literature was reviewed. Results The patient, 69 year-old, female, was initially present with shin lesion on one finger and abnormal myelogram. The histopathology of shin lesion showed that tumor cells were composed of large cells with abundant cytoplasm,the nuclei were large and irregular, and were infiltrated by Neutrophil and eosinophil. The CD30,CD3 and CD43 of tumor cells were positive, but ALK negative by immunohistochemical method. The number of WBC in peripheral blood was 15.5×109/L and 51 archaeocytes were in every 100 karyotes. Bone marrow aspiration detection showed that bone marrow was hyperplasia and the ratio of myeloblast was 78 %. This patient was diagnosed as C-ALCL-AML, partly differentiation type(AML-M2a). Conclusion C-ALCL-AML is very rare. Its diagnosis is dependent on clinical data, histopathology and immunohistochemical markers. The first choice of treatment is chemotherapy, but its prognosis is poor.

Objective To investigate the correlation between relative cerebral blood volume (rCBV) and tumor character of meningiomas. Methods Thirty-six (GradeⅠ: n=30, GradeⅡ+Ⅲ: n=6) patients with meningioma underwent conventional MR and perfusion weighted imaging (PWI) . The pulse sequence of PWI was single shot GRE-EPI-T2~*WI. The CBV maps were calculated from the original data of perfusion images and the maximum rCBV of meningiomas was acquired from CBV maps through measurement on the region of interest (ROI). The differences of rCBV in tumor and edema between benign and malignant tumors were analyzed. Results The mean rCBV in tumor of benign meningioma (9.78±4.69) was higher than that of malignant ones (3.59±0.28) (t=7.168, P<0.001). The mean rCBV in edema of benign and malignant meningiomas was 3.06±1.76 and 3.58±1.93, respectively (P>0.05). Conclusion CBV map and quantitative study of rCBV are feasible for differential diagnosis of meningiomas and have instructive function for clinical treatment and assessment of prognosis.
