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.

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

Objective To analyze the common and individual training needs of palliative care among nurses in different level hospitals. Methods The self-designed questionnaire about training needs of palliative care was used to investigate 340 nurses in different level hospitals. The data were analyzed by Ridit analysis method. Results There were 24 important items and 26 unimportant items in the common training needs. Regarding the individual training needs,the concept of palliative care,basic nursing care and bereavement support were preferred by the primary-level hospital nurzes,while the principles of palliative care,basic nursing care and pain management in secondary-level hospital nurses,radiotherapy and chemotherapy care and the ethical and moral problems in palliative care in third-level hospital nurses. Conclusion Different level hospital nurs-es have beth common and individual needs in the training contents of palliative care. Ridit analysis can distinguish the differ-ences and provide reference for the training.

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.

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 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.

Objective: To imrove the current situation that disinfection is inconvenient and ineffective when infant incubators are used. Methods: To make some improvements without changing the structure and performance of existing infant incubators. Results: Built-in disinfection device is designed to overcome the difficult operation, poor effect and inconvenience in use. Conclusion:It has been awarded“the state utility model”for its safety and convenience (patent no:ZL200520117573.9).

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 .
