From 2004 to 2005,In order to find the impact on the children`s behavoir in the one parent family, we selected the parents divorced family and the normal family to compare the behavior difference of 5-6 years old children from 45 families ,in them, 19 boys and 31 girls. In group one, 15 families,only the mother take care the children, In group two,15 families, Only the Father take care the children .In group three,only the Grand Parents take care the children, in Group four, we select 15 normal families`s Children. They have the similar ages, after checking in their expression,character and the intelligence, The average score of group1,2and 3 on expression is 138,the score of the group 4 is 195, the different ratio data (P

Gastroesophageal reflux disease( GERD)is a common gastrointestinal disorder during pregnancy. Several factors including decreased lower esophageal sphincter pressure, increased intra-abdominal pressure secondary to the enlarged gravid uterus and alteration in gastrointestinal motility have been linked to the pathogenesis of GERD. Diagnosis and treatment of diseases during pregnancy are unique. Life-style modifications are helpful for the majority of patients. When considering medical therapy,a step-up therapy from antacids,H2 receptor antagonists to proton pump inhibitors should be followed. In patients without a prior history of reflux,symptoms usually are relieved after delivery.

Although anterior cervical fusion has been a conventional surgical treatment for cervical spondylosis, concerns for the possible accelerated degeneration of adjacent segments after fusion have been growing. Fusion can also lead to other drawbacks, such as alteration of spinal biomechanics, graft and hardware complications, and chronic pain at the harvest site. In addition, it must be realized that decompression, not fusion, is the primary goal of anterior cervical surgery. Since the artificial cervical disc replacement can preserve enough motion after neural decompression with adequate stability, it provides a new surgical therapy for cervical spondylosis. This paper summarizes the progress in the related research field and makes comments on the current developments and future prospects of cervical arthroplasty.

Objective To investigate the diagnostic value of growth hormone(GH) stimulating test in dwarfism of children and related influencing factors .Methods Arginine and L‐dopa were applied to perform GH stimulating test in 642 children with dwarf‐ism .GH levels were detected at 30 ,60 ,90 ,120 ,150 ,180 min after stimulation .All children were divided into GH deficiency (GHD) group ,with peak value of GH less than 10 ng/mL ,and non‐GHD group ,with peak value of GH at least 10 ng/mL .Physical and la‐boratory data of the two groups were compared .Results The proportion of children with GHD and without GHD were 68 .69%and 31 .31% ,respectively ,and with statistical difference(χ2 =6 .19 ,P<0 .05) .The GH peak value ,with a delay ,mainly appeared at 30 and 150 min after stimulation ,accounting for 22 .42% and 34 .27% .Levels of age ,body height standard deviation ,body mass in‐dex ,alanine aminotransferase ,aspartate aminotransferase ,insulin growth factor‐1 and 25‐hydroxyl vitamin D were statistically dif‐ferent between the two groups(P<0 .05) .Conclusion Arginine and L‐dopa combined stimulating test could be used for the diagno‐sis of GHD in children with dwarfism .GH level might be correlated with various physical and laboratory parameters ,which should be considered for the diagnosis of GHD .

Objective The anti tumor and anti metastasis effects of angiocytotoxic therapy (TNP 470/Gemcitabine) were investigated using a model of human pancreatic carcinoma by surgical orthotopic implantation (SOI). Methods The SOI model was developed by suturing small pieces of SW1990 tumors into the tail of pancreas in nude mice. Twenty four male mice were randomly divided into control group, G100 group receiving 100 mg/kg Gemcitabine intraperitoneally injection on days 0,3,6 and 9 after transplantation, and T30 group receiving 30 mg/kg TNP 470 subcutaneous injection on alternate days for 8 weeks. Another thirty two male mice were randomly divided into control group, T15 group, G50 group and combination group (TNP 470 30 mg/kg+ Gemcitabine 50 mg/kg). Animals were sacrificed ten weeks after transplantation. Results G100 group had a significant inhibitory effect on tumor growth of pancreatic carcinoma compared to T30 group, while the metastasis of tumor was significantly inhibited by T30 group compared to G100 group. Neither G100 group nor T30 group showed a significant improvement on survival rate. T15 group and G50 group alone had no significant inhibitory effect on the tumor growth and its metastasis. Mean while a significant anti tumor, anti metastatic effect and a significant improvement on the survival rate were observed in combination group. The inhibitory effect of G50 group was enhanced by 2 times with T30, and 2/8 of the tumors bearing animals were cured by the combination therapy. The level of microvessel density in T30 group was significantly lower than that in T15 group and control group ( P

0.05).The gender ratio(male-to-female)、the HBV infection rate and the 3-year recurrence rate after surgery in Group FH was higher than that in Group NF(P

Objective　To investigate the effects of a wide range of concentrations of As2O3 malignant lymphoma cell lines. Methods　Cell apoptosis situation ,cellular DNA contents and bcl-2 protein expression were determined by cell stain, TdT-mediated dUTP Nick-end Labeling (TUNEL) and flow cytometry. Results　0.5 μmol/L～2.0 μmol/L As2O3 could inhibit Raji cell growth accompanied by the appearance of morphologic characteristics of apoptosis. Number of sub-G1 cells significantly increased and bcl-2 protein expression in Raji cells was significantly down-regulated assayed by flow cytometry. The relationship between bcl-2 protein and the concentrations of As2O3 showed a dose-and time-dependent effect; so did the number of sub-G1 cells. However, there was no effect of 0.5 μmol/L～4.0 μmol/L As2O3 on Jurkat cell.Conclusion　It is found that As2O3 could significantly inhibit the growth of B lymphoma cell lines and induce their apoptosis.

ObjectiveTo observe the efficacy and safety of house dust mite vaccine in the treatment of house dust mite-allergic rhinitis.Methods47 patients with allergic rhinitis were recruited into the study.The course of SIT was treated by house dust mite vaccine for 51 weeks.Self-contrast method was used to compare the symptom score,nasal airway resistance before and after treatment.Then we observed the security in the process of injection.ResultsThe symptom score was (7.40 ± 1.64) vs ( 3.40 ± 1.50 ) pre and post therapy.Nasal airway resistance were (2.02 ±0.72) vs ( 1.06 ± 0.81 ) kPa · s -1 · L-1.Both the values of the data had significant differences( t =15.49,4.44,all P ＜ 0.01 ).No serious adverse reaction was observed.ConclusionSIT was able to improve the clinical symptoms and decrease nasal airway resistance.House dust mite vaccine was an effect and safe drug for the dust mite allergic asthma patients.

Objective: To study clinical significance of endogenous vitamin C 、 E in patients With hypertension and stroke. Methods: The serum vitamin C、 E, Malondialdehyde (MDA), superoxide dismutase (SOD) were determined by ultraviolet spectrophotometry in patients with hypertension (23 cases)、 hypertensive cerebral hemorrhage (CH, 30 cases)、 ischemic cerebrovascular disorders (IC, 25 cases) and control groups (20 cases). Results: Compared with control group, at acute stage of stroke, the Vit C、 E and SOD levels significantly reduced (P＜0. 01), the MDA level significantly increased (P＜0.01); at convalescent stage, the Vit C、 E gradually recover to normal, the SOD still reduced (P＜0.05), the MDA still incresed (P＜0.05). Conclusion: The endogenous Vit C、 E have significant change in patients with acute stage of stroke, it gradually recovers to normal in convalescent stage. Meanwhile the SOD and MDA change accordingly.
