Clinical, neuroimaging, and pathologic studies suggested that a variety of nonmotor symptoms, such as olfactory dysfunction, dysautonomia, and mood and sleep disorders, can precede the typic motor features of Parkinson disease (PD) by years and, perhaps, even decades. The period when these symptoms arise can be referred as the premotor phase of the disease. This paper reviewed the conception, clinical manifestation, pathology, diogose of the premotor phase of early Parkinson disease.

Objective To investigate the effects of low-dose of hydrocortisone on circulating thymus-dependent lymphocyte (T lymphocyte) apoptosis in patients with septic shock. Method fifty-seven patients with septic shock admitted into ICU from January 2006 to January 2009 were prospectively randomized (random number) to treatment group and control group. Another 20 healthy volunteers and 18 patients with sepsis alone were included as external control groups.The patients of treatment group and control group were treated with low-dose of hydrocortisone and placebo,respectively. Samples of peripheral blood were taken from healthy volunteers and patients 0 hr,24 hrs,48 hrs,72 hrs and 168 hrs after onset of the disease to determine the circulating T lymphocyte apoptosis by using the assays of Annexin V and flow cytometry. Least significant difference t -test was used for multiple comparisons. Results The percentage of Annexin V-positive CD4+ T lymphocytes in the primary stage was (11.01 +4.52)% in septic shock patients, (4.41 + 1.45)% in healthy volunteers, and (7.87 + 3. 82)% in patients with sepsis alone. And in the initial setting, the percentage of Annexin V-positive CD4+ T lymphocytes in the septic shock patients was higher than that in healthy volunteers ( P < 0.05) and in patients with sepsis alone ( P < 0.05). The percentage of Annexin V-positive CD8 + T lymphocytes at the beginning was (11.33+19.62)% in septic shock patients, (9.62+8.32)% in healthy volunteers, and (13.09+ 15.84)% in patients with sepsis alone (P > 0.05 between three groups). The percentages of Annexin V-positive CD4+ T lymphocytes in control group after 24 his, 48 hrs and 72 hrs were(13.51+6.85)%, (19.39 + 6.63)% and (15.33+ 6.21)%, respectively. And the percentages of Annexin V-positive CD4+ T lymphocytes in treatment patients after 24 hrs, 48 hrs and 72 hrs were (17.4 + 7.21)%, (22.61 + 5.64)%, and (25.73 + 6.91)%, respectively. The percentage of Annexin V-positive CD4+ T lymphocytes in septic shock patients was higher than that in control groups ( P < 0.05). The percentages of Annexin V-positive CD8+ T lymphocytes in control group after 24 hrs, 48 hrs and 72 hrs were (11.49+ 11.73)%, (12.74+ 10.39)% and (13.28+ 16.6)%, respectively, and in the treatment group, those were (9.49 + 8.9)%, (15.32+18.17)% and (13.68+16.84)%, respectively (P >0.05 between two groups). In the meantime, the percentages of Annexin V-positive CDS'1' T lymphocytes in control group and in treatment group were (12.72+ 19.69)% and (13.88 + 13.28)%, respectively (P >0.05). Conclusions Low-dose of hydrocortisone could induce CD4+ T lymphocyte apoptosis and has no effects on CD8+ T lymphocyte apoptosis when it is used to treat septic shock.

Objective To evaluate and analyze the postoperative complications induced from the procedure for prolapse and hemorrhoids(PPH).Methods The data of the third or fourth degree hemorrhoids operated by pro- cedure for prolapse and hemorrhoids were analyzed.Results Total 224 patients with hemorrhoids were operated on by PPH,and the mean operative time was 25 minutes and mean postoperative hospital stay were 3.5 days.Postoper- ative bleeding requiring haemostatic procedures occurred in two patients.Urine retention rate was 30.36%,there were 56 eases pain scores＞5,there of re-prolapse,16 cases of residual skin tags.One case of mucocele.Conclusion The rule of PPH is individual management.

Objective To investigate the mechanism of Shengji-hongfen Cream(SJHFC)affecting basic fibroblast growth factor(bFGF)in wound and hastening wound healing.Methods Rabbit models of cutaneous deficiency and infection were setup.Self-contrast observation was used for comparing the two wound sides of model rabbit,which were administrated with SJHFC(treatment group)and vaseline(control group)respectively.Microstructure of wound surface and changes of bFGF weTe observed and measured.Results The content of fibroblasts,phlogocyte,collagen and blood vessel in the SJHFC group increased markedly,compared with the control group after one week.The content of bFGF was significantly changed than the control group at the 3rd and 7th day(P<0.05).Conclusion SJHFC Can promote bFGF content of the wound,that maybe the mechanism of its hastening wound healing.

OBJECTIVE To investigate vascular endothelial growth factor-C (VEGF-C) and cyclooxyegense-2(COX-2) expression in nasopharyngeal carcinoma. METHODS The expression of COX-2 and VEGF-C were stained respectively in nasopharyngeal carcinoma tissues of 45 patients using immunohistochemical method,and were analyzed with clinical data. RESULTS The positive expression rates of COX-2 and VEGF-C were 68.9 % and 53.3 % respectively in nasopharyngeal carcinoma tissue. The expression of COX-2 was positively correlated with VEGF-C (r=0.334,P

OBJECTIVE: Observing the anatomic variation and measuring the bone volume of meatus and nasal cavity by analyzing the expression of paranasal sinus CT. Searching whether these variation and volume data are related to maxillary fungal ball. METHOD: Measuring the double side bone volume of middle meatus,nasal cavity and the rate of middle meatus volume in the same side of nasal cavity respectively in the normal group, the maxillary fungal ball group. Observing the anatomic variation and statistically evaluating the anatomic variation and volume of nasal cavity and nasal meatus. RESULT: In the maxillary fungal ball group, the affected side and the contralateral side volume of middle meatus,nasal cavity and the rate of middle meatus volume in the nasal cavity had no statistical difference (P>0.05); Comparing the middle meatus volume and the rate of middle meatus of the maxillary fungus ball group affected side and normal group,there was statistical difference (P<0. 05). In the maxillary fungal ball group and the normal group, the morbidity of deviation septum were 24. 24% and 33. 33%, the morbidity of OMC variation were 30. 3% and 26. 67% (P<0.05), the morbidity of nasal anatomic variation were 54. 55% and 60.00%, there was no statistical difference (P>0.05). CONCLUSION Maybe there is a correlation between the enlarged bone middle meatus and the maxillary fungal ball. There is no relationship between the nasal anatomic variation and the maxillary fungal ball.
