Objective To investigate the changes of psychological state and family environment of the patients with neurosis (including depression and anxiety) in the process of treatment. Methods The Hamilton depression scale (HAMD), Hamilton anxiety scale(HAMA), self-rating depression scale(SDS), self-rating anxiety scale(SAS), family environment scale(FES), and family adaptability and cohesion scale(FACESⅡ-CV) were used to evaluate the changes of psychological state and family relationship in the process of treatment among patients with depression and anxiety hospitalized in general hospitals (n=45) and their family members (n=45). Results Before intervention, values of HAMD, HAMA, SDS and SAS in patients were higher than normal ones, and were in line with the corresponding diagnostic criteria. After psychological intervention and medication for 2 to 3 months, symptoms such as depression and anxiety were improved significantly, and values of the above scales were within normal ranges. Besides, there was also significant improvement in FES and FACESⅡ-CV after intervention among the patients. All the values of the family members were in the normal ranges before intervention, however, significantly positive changes were observed after intervention. Conclusion With the improvement in depression and anxiety after intervention among patients, the psychological pressure of family members is released, and family relationship is partially restored. The rehabilitation of patients plays an important role in the restoration of family function.

Objective To study the feasibility, superiority and experience of minimally invasive laparoscopic-assisted surgery of the thyroid using ultrosonic scalpel. Methods In a period from January, 2006-August, 2008, 56 patients of the department of general surgery, the hospital of Heilongjiang Province were diagnosed as thyroid node. The size of the nodes ranged from 5.0 cm×4.2 cm to 3.5 cm×2.0 cm in uhrosonography. An incision of about 1.5-2.0 cm was made 1.0 cm above the suprasternal notch and the operation was performed with ultrosonic scalpel assisted with laparoscope. Partial thyroideetomy of lateral thyroid was performed in 20 cases, subtotal thyroidectomy in 25 cases, subtotal thyroidectomy of unilateral thyroid and partial thyroidectomy of contralateral thyroid respectively in 1 case, partial thyroidectomy of bilateral thyroid in 10 cases. Results All 56 cases have undergone minimally invasive laparoscopic-assisted surgery successfully in 50-146 min and no complications occurred. Fifty five cases were confirmed to be benign lesion pathologically. Conclusion Laparoscopic-assisted surgery of the thyroid is an effective with a good cosmetic result.

Objective:To observe the curative effects of the combined application of domperidone, pantoprazole and hydrotalcite tablets in the treatment of bile reflux gastritis ( BRG) and explore the underlying mechanism. Methods:Totally 80 patients with BRG were randomly divided into the treatment group and the control group with 40 cases in each. The treatment group was received panto-prazole, hydrotalcite tablets and domperidone, and the control group was treated by hydrotalcite tablets and domperidone. The efficacy was observed in both groups after 4 weeks. Results:The effective rate of symptom relief in the treatment group and the control group was respectively 92. 5% and 62. 5% (P<0. 05). After the 4 week treatment, the gastritis healing rate in the treatment group was higher than that in the control group (P<0. 05). The improvement of gastric mucosal hyperemia, edema and erosion in the treatment group was better than that in the control group with significant difference (P<0. 05). Cholic acid in gastric juice and gastric acid se-cretion were significantly reduced in both groups after the treatment, while the reduction of gastric acid secretion in the treatment group was more notable than that in the control (P<0. 05). Conclusion:Pantoprazole can be used to control BRG, and the combination of the three drugs shows better efficacy in the treatment of BRG.

To investigate the different expression of Fas, Fas L and Caspase 3 in hypertrophic scars and normal skins in order to explore their influences on scar formation, the expression intensity and distribution of Fas, Fas L and Caspase 3 were detected by immunohistochemistry and pathological methods in 8 cases of hypertrophic scars and 8 cases of normal skins. In normal skins, Fas and Fas L were mainly located in the cellular membranes and cytoplasms of epidermal cells and some fibroblasts. Caspase 3 was mostly distributed in epidermal basal cells and some fibroblasts. In hypertrophic scars, Fas and Fas L were principally existed in the membranes and cytoplasms of epidermal keratinocytes. The positive cellular ratio of two proteins was significantly reduced ( P

The purpose of this study was to investigate the localization and expression characteristics of phosphorylated form of extracellular-signal regulated-protein kinasel/2 (p-ERKl/2), Ras and C-fos in skin at different development stages and to explore their potential biological significance. Immunohistochemistry and pathological methods were used to detect the expression intensity and distribution of p-ERKl/2, Ras and C-fos in skin of 8 fetuses with different gestational ages (13 to 31 weeks) and 8 adults. Positive immunohistochemical signals of p-ERK1/2, Ras and C-fos. could be found in fetal and postnatal skins. Along with the increment in gestational age, the positive cell rates of p-ERK1/2, Ras and C-fos in the skin elevated progressively. In skins derived from the fetus of late-trimester pregnancy and adult, the positive rates of these three proteins were significantly increased in comparison with skin from the early-trimester fetus (P

Localization and expression of two subunits (IGF ⅠR? and IGF ⅠR?) of insulin like growth factor Ⅰ receptor and phosphorylated tyrosine proteins (P Tyr) in skins at different developmental stages were studied in order to explore their potential biological significance. Immunohistochemistry and pathological methods were used to detect the expression intensity and distribution of IGF ⅠR?, IGF ⅠR? and P Tyr in skins of 12 fetuses with different gestational ages and 8 adults. The results showed that positive immunohistochemical signals of IGF ⅠR?, IGF ⅠR? and P Tyr could be found in fetal and adult skins. Along with growth and development of the fetus, the positive cell rates of IGF ⅠR?, IGF ⅠR? and P Tyr in skins elevated progressively. In adult skins, IGF ⅠR was mainly located in the cell membrane of epidermal cells, while P Tyr was chiefly distributed in epidermal cells and some fibroblasts. These results suggested that IGF ⅠR and its mediating signaling pathway might be involved in cutaneous development at embryonic stage, in cutaneous structure and function maintenance, and in wound healing at postnatal stage.

Angiopoietin family is a recently discovered type of cellular factors that specifically bind to the TIE-2 receptors located exclusively in endothelial cell membrane. The protein structures of this family members are similar. They can be structurally divided into three domains: an N-terminal region lacking homology to any known structures, an alpha-helical rich coiled-coil segment, and a fibrinogen-like domain. The distribution and biological activity of these factors are different in organism. Angiopoietin-1 as a agonist, mostly locates in close proximity with vascular endothelial cells, keeps the stability of blood vessels, enhances the affinity of vascular endothelial cells with surrounding cells and matrix, decreases the leakage of vessel. Ang-2 is a naturally occurring antagonist of Ang-1, exists in the angiogenic remodeling region and is related to the decrement of the stability of vessel. Ang-3 is widely distributed in multiple mouse tissues, while Ang-4 is expressed only in lung. Although Ang-3 and Ang-4 are structurally diverged from each other, they appear to represent the mouse and human counterparts of the same gene locus. Biological functions of Ang-3 and Ang-4 have not been elucidated yet. Angiopoietin family has potentially clinical applications for incurring illnesses which lead to vessel wound and vascular abnormal development.

To explore the change in gene expressions of p38 mitogen-activated protein kinase (p38MAPK) and its upstream signal-regulated molecule (mkk3 and mkk6) in normal skin versus hypertrophic scars underlying its potentially biological significance. Total RNAs were isolated from 8 specimens of hypertrophic scars and 8 specimens of normal skin, then they were purified to mRNAs, and the gene expression of mkk3, mkk6 and p38MAPK was examined with reverse transcription-polymerase chain reaction (RT-PCR). The results showed that the intensities of gene expression of mkk6 and p38MAPK were weak in normal skins, while the expression of these 2 genes was significantly elevated in hypertrophic scars compared with normal skins (P0.05). In hypertrophic scar, the elevation of mkk6 and p38MAPK gene expression, which plays pilot roles in cell proliferation, may be one of the mechanisms controlling the formation of hypertrophic scars.

To investigate the effect of FGF-10 on the secretion of GM-CSF by adult keratinocytes in vitro and to understand the mechanisms involved in the stimulation of granulation tissue formation by FGF-10 during wound healing. Concentrations of FGF-10 used were 4, 16, 125 and 500 ng/ml. Cells were seeded in the amount of 2 500 cells/cm 2 or 5 000 cells/cm 2 in dishes in serum-free medium, and supernatants were collected at 24, 48 and 72 hours after culture. The amounts of GM-CSF in cell culture supernatants were determined using GM-CSF ELISA kits, and cell numbers were counted by haemocytometer. For cells seeded in low density (2 500 cells/cm 2), GM-CSF was not detected at 24 hours. At 48 hours, both in absolute concentrations and on a per-cell basis, the amounts of GM-CSF secreted in cultures with 125 and 500ng/ml FGF-10 were significantly higher than that in negative control (P0.05). At 48 hours, the keratinocytes in the middle area were confluent, and a number of cornified cells were observed, while the productions of GM-CSF in FGF-10 cultures were not higher than that in negative control. There was a clear negative correlation between the secretion production of the growth factor and the total cell number in each dish with a correlated coeffecient of 0.881 (P
