Objective To evaluate the expression of TGF? 1 in rat testes after vas deferens ligature and release again. Methods Ninety rats were randomized into 3 groups:vas deferens ligature in 35 rats,release again after ligature in 20,sham-operation in 35.Immunohistochemical staining and hybridization in situ were used to detect the expression of TGF? 1. Results The expression of TGF? 1 in vas deferens ligature group was higher than that in sham-operation group after 8 weeks ( P

Objective To analyze the clinical effect of treating adjacent multi-vertebral tuberculosis by anterior radical debridement, titanium mesh bone fusion and internal fixation. Methods Twenty-four patients with adjacent multi-vertebral tuberculosis were treated by anterior radical debridement, titanium mesh bone fusion and internal fixation from April 2002 to May 2004. There were different types of tuberculosis symptoms in all the cases, including local pain and preoperative kyphosis deformity, and paraplegia in 6 cases. The preoperative kyphosis angle was 27.5??3.5?. After intensive anti-tuberculosis medication for 2 to 4 weeks before operation, 24 patients were reconstructed with Ti-Mesh filled with autograft rib and anterior internal fixation. After operation, the anti-tuberculosis medication was continued for one year. Results All the patients were followed up for 1.5 to 2.5 years postoperatively, with the average of 1.9 years. Their focus was eliminated completely, all the wounds healed in the first stage. The postoperative kyphosis angle was 5??2.5?. The average subsidence of Ti-Mesh was (3.5?0.5) mm at 8th weeks postoperation and the loss angle of kyphosis correction was 4.1??1.0? at lastest follow-up. Ti-Mesh began to fuse 3 to 6 months after operation. No looseness and dislocation were found during follow-up period. 6 patients with paraplegia recovered completely after 6 months, and kyphosis was rectified. ESR of these patients reduced a month after operation and reached to normal level after 6 months. Conclusion Anterior radical debridement, titanium mesh bone fusion and internal fixation show good results in treatment of adjacent multi-vertebral tuberculosis. The large bone deficit in the spine after debridement can be successfully reconstructed and kyphosis can be rectified. As the result of a better stability of the spine, secondary paraplegia can be avoided, and there is no need for iliac bone harvest, so without any relative complications.

Objective To investigate the apathy and neuropsychological characteristics of newly diagnosed Parkinson's disease (PD) patients.Methods Eighty-two newly diagnosed PD patients and 30 matched healthy controls by age,sex and education level were recruited in the present study.Apathy was assessed using Apathy Evaluation Scale (AES) and related factors,including age,sex,education level and disease duration were simultaneously evaluated.Unified Parkinson's Disease Rating Scale (UPDRS),Hamilton Depression Rating Scale (HAMD),as well as Montreal Cognitive Assessment (MoCA) were employed in order to respectively evaluate the motor function,depression and cognition.Results The AES scores in the PD patients were significantly higher when compared to the healthy controls.The prevalence of apathy and depression in the PD patients was 51.2％ (42/82) and 19.5％ (16/82),respectively.There were no statistically significant differences in age,sex,education level,UPDRS-Ⅱ/Ⅲ scores and MoCA scores between apathy (n =42) and no-apathy (n =40) PD patients (P ＞ 0.05),while the statistically significant difference in HAMD scores between apathy (n =42) and no-apathy (n =40) PD patients was shown (the HAMD scores of apathy PD patients were 10.61 ± 3.30,the HAMD scores of no-apathy PD patients were 5.96 ± 1.90,t =7.87,P ＜ 0.05).The correlation analysis indicated that there were no correlations between AES scores and the related factors,including age,education level,disease duration and UPDRS-Ⅱ / Ⅲ scores,but AES scores were positively correlated with HAMD scores.Conclusion In newly diagnosed PD patients,the apathy is independent of depression,motor dysfunction,as well as cognitive impairment,which may be an early signal for PD.

To study photosynthetic characteristics and its influencing factors in leaves of medicinal plant Mirabilis himalaica, and provide an evidence for guiding artificial planting and improving the quantity. The light-response and diurnal photosynthesis course of leaves at the booting stages of 1-3 year old M. himalaica were measured with LI-6400 system. The Results showed that the light response curves were fitted well by non rectangle hyperbola equation (R2 > or = 0.98). The values of the maximum photosynthetic rate (Pmax) and light use efficiency of three-year old M. himalaica leaves were higher than those of 1-2 year old individuals. The diurnal variation of net photosynthetic rate (Pn) and stomatal conductance (Gs) of 2-3 year old M. himalaica were typical double-peak curves determinately regulated by stomatal conductance. However, transpiration rate (Tr) of 1-3 year old plants leaves were single-peak curve, which was self-protection of harm reduction caused by the higher temperature at noontime. Correlation analysis showed that the changes between photosynthetic active radiation (PFD), air temperature (T ) and Pn, were significant positive related. Therefore, M. himalaica is a typical sun plant, which should be planted under the sufficient sunshine field and prolong the growing ages suitably in order to improve the yield.

The clinical data of patients with hypoparathyroidism accompanied by elevated and normal muscle enzymes were analyzed retrospectively.The results showed that there were no differences in age,gender,pathogenesis,etiology,and parathormone level between groups with elevated muscle enzyme and normal muscle enzyme.Serum calcium concentration in the group with normal muscle enzyme was within normal range.Serum calcium concentration in the group with elevated muscle enzyme was significantly lower than that in the group with normal muscle enzyme (P＜0.01).As the serum calcium concentration rose,the elevated enzyme level gradually returned to normal range,suggesting that the decrease of serum calcium concentration resulted in the elevated muscle enzyme levels in patients with hypoparathyroidism.

Objective To improve the understanding of autoimmune disease related panereatitis by analyzing their clinical features.Methods The clinical features were analyzed retrospectively in 28 autoimmune disease related pancreatitis cases from Peking Union Medical College Hospital(PUMCH),according to the associated autoimmune diseases.Results (1)The average age was(40.0±16.1)years,and the ratio of male to female patients Was 1:6.There were 24 acute and 4 chronic pancreatitis in the 28 cases.(2)The common related autoimmune diseases were systemic lupus erythematosus(20/28)and Sjogren's syndrome(6/28).(3)The characteristics of the autoimmune diseases was multi-system involvement,such as hematologic system,kidney,liver,etc.(4)Clinical features of those acute pancreatitis shown that no distinct trigger exist for acute pancreatitis.and the radiological changing Was not prominent.(5)In laboratory examination,an obvious increase of CA199 coaid be seen,paralleling the severity of pancreatitis.(6)Glucocorticoids or immunosuppressors was effective,and the mortality rate of acute pancreatitis cases was 33.3%.ConclusionsAutoimmune disease related pancreatitis is dominant with acute pancreatitis and females is common,which may reflect the activity of autoimmune diseases.Autoimmune disease related acute pancreatitis has a high mortality rate.Glucocorticoids and/or immunosuppressors may be useful to relieve the pancreatitis.
