Objective To investigate the subthreshold depression for long-term survivors after breast cancer surgery and its effect on their quality of life (QOL). Methods The self-made general questionnaire, Centre for Epidemiological Studies Depression Scale (CES- D), Hamihon Rating Scale for Depression and Functional Assessment of Cancer Therapy- Breast were used to investigate the subthreshold depression and its effect on their QOL for 210 long-term survivors after breast cancer surgery. The difference in general conditions and score of QOL between the subthreshold depression and non-subthreshold depression groups was also compared. Results The subthreshold depression with incidence rate of 46.67%(98/210) was observed for the log-term survivors after breast cancer surgery in this study. The results indicated that the age (≤50) (OR=5.627, 2.662,P<0.01), marriage (unmarried, divorced or widowed) (OR=5.087, P<0.01), employment (unemployed, sick leave or retired) (OR=2.077,P<0.05) and low income (<3000 RMB/month) (OR=3.375,P<0.01) were the key factors that led to the occurrence of subthreshold depression. The score of QOL for the subthreshold depression group were lower than those of the non-subthreshold depression group (t=-6.653--2.926,P<0.01), and had a significantly negative correlation with score of depression and QOL (β=-0.362--0.132). Conclusions A high incidence rate of subthreshold depression for long-term survivors after breast cancer surgery was observed. The incidence rate of subthreshold depression increased for the patients with younger age, low income,unmarried or unemployment. Due to their low QOL, attentions should be paid to the early detection and early prevention for the long-term survivors with subthreshold depression after breast cancer surgery.

Objective To evaluate the relationship of gastric function of its proximal portion and electrogastrogram in healthy youths with obesity.Methods A total of 35 healthy young volunteers with normal weight participated in the study,including 16 females and 19 males.On the first day,the water load test was performed.On the second day,determination of function of proximal portion of stomach was done using electronic barostat and electrogastrogram.Results Water load test:females were found to consume significantly less water than males(P0.05)between male group and female group in the minimal distention pressure(MDP),initial intragastric pressure(IP)and the maximal tolerance pressure(MP).The initial gastric compliance(IC)in female group was less than that in male group(P0.05).The parameter of EGG:with the intragastric pressure increased,DF in Normal Range(N%)showed decreasing tendency,while bradygastria(B%),tachygastria(T%),instable coefficient of dominant frequency(DFIC)and dominant power(DP)increased.Conclusion The gastric capacity,the parameters of visceral sensitivity and IC are remarkably different between sexes.The gastric electrical activity varies in different states of proximal gastric function.The gastric contraction may be enhanced by an improvement of dominant power(DP).

Objective To introduce a method of comprehension correction for secondary lip-nasal deformities after operation of the completely unilateral cleft lip. Methods The correction consisted of the following procedures: reposition of the columella and nasal alar crus by one tractional suture with nostril base narrowing; modification of flat nostril by a MT-plasty at the edge of naris; arising of the nasal alar and nasal dorsor by ePTFE implantation; reconstruction of the Cupid's bow by M type incision and vermilion advancement; repair of the vermilion deficit with the hinge mucosal flap and bipedicle mucosal flaps of the lower lip. Results Twenty-one cases with secondary lip-nasal deformities were successfully corrected by these comprehensive methods. Ten of them were followed-up for three months to 1 year with satisfactory effects. Conclusion The comprehensive methods can be used to correct satisfactorily the secondary lip-nasal deformities after operation of the completely unilateral cleft lip.

The inhibitory effects of total glucosides of Moutan Cortex (TGM) and to talglucosides of Paeony Lactiflora (TGP) on osmotic hemolysis and oxidative hemolysis induced by hydrogen peroxide were studied. TGM at lower concentration and TGP could inhibit osmotic hemolysis significcantly, but higher concentration (100mg ? L-1) of TGM had a hemolytic activity. TGM and TGP could inhibit hemolysis induced by H2O2 significantly,but TGM was more effective than TGP. TGM .TGP and Vit E all could inhibit lipid peroxidation and glutathione depletion, induced by H2O2, on erythrocytes.

BACKGROUND: Previous studies has explored the effects of nerve growth factor (NGF) on cultured rabbit Schwann cells as well as preparation of acellular nerve allografts, in addition, the neural complex was prepared in vitro.OBJECTIVE: To investigate the effect of acellular nerve allografts on the functional recovery and reconstruction of the nerve-muscle structure of the sciatic nerve defect in rabbits.DESIGN, TIME AND SETTING: The randomized controlled animal experiment was performed at the Center Laboratory of Third Hospital of Hebei Medical University from March 2006 to June 2007.MATERIALS: Totally 37 healthy, adult, New Zealand, white rabbits were selected. One rabbit was prepared for extracted nerve bridge, and the others were randomly divided into the experimental and control groups, with 18 animals in each group.METHODS: The double sides of sciatic nerve were removed, divested surrounding tissues, and cut into 3 cm segments, then placed in TdtonX-100 solution for 12 hours, washing with distilled water. The procedure was repeated, and TritonX-100 totally used for 96 hours. Then the extracted nerve bridge was conserved in Hank's solution at temperature of 4 ℃. The concentration of 2~(nd) passage Schwann cell was regulated to 1 ×10~(11)/L, and injected to extracted nerve bridge, followed by DMEM culture, to obtain neural complex. Rabbits in the experimental group were prepared a 20 m defects above knee joints, and the recellularized neural complex were transplanted into the defective sciatic nerve. Rabbits in the control group were prepared by transplanting extracted nerve bridge without Schwann cells.MAIN OUTCOME MEASURES: The elcosis and healing of feet were observed at weeks 4, 8, and 16 after operation, meantime,the recovery of axon of distal end peroneal nerves, myelin sheath, tibialis anterior, as well as motor end plate were detected by electromyogram, light microscope and transmission electron microscope.RESULTS: At weeks 4, 8 and 16 after operation, the rejection was not found in the operating field. The experimental group was better than the control group in healing of ulcers, the number of nerve fibres, the ultramicrostructure of medullary sheaths, the regeneration nerve, the structure of the motor end plate and muscle. At 4 weeks after operation, no nerve conduction was found in 2 groups, but at weeks 8 and 16 after operation, the experimental group was better than the control group in wet weight of tibialis anterior muscle and nerve conduction velocity (P < 0.05).CONCLUSION: The recellularized neural complex can significantly promote the reconstruction of the nerve-muscle structure and functional recovery of injured sciatic nerve.
