Object To develop and utilize a folk-medicine of Yunnan Province, Lethariella cladonioides (Nyl.) Krog. Methods The constituents were extracted with 80% ethanol and isolated with silica gel column chromatography. The structures were identified by physicochemical properties and spectral analysis. Results Two unknown constituents were elucidated from the extract as 3-aldehyde-6-methyl-2, 4-dihydroxy-ethyl-benzoate (Ⅰ), and 4-methyl-2, 6-dihydroxy-benzaldehyde (Ⅱ). Conclusion They are both new constituents obtained firstly.

Objective To explore the pathologic factors influencing the long-term survival of patients with relapsing and/or metastatic colorectal cancer (CRC) after radical operation for founding a basis for the clinical treatment protocols.MethodsThe clinical data were collected of 132 patients who were with relapsing and/or metastatic colorectal cancer (CRC) after radical resection,hospitalized from the beginning of 2002 to the end of 2007,and had integrated hospitalization and follow-up data.The relationship between the clinic pathologic factors and long-term survival was retrospectively analyzed.ResultsUnivariate analysis showed that the survival rate was higher in the patients with single recurrence and/or metastasis than in those with multiple recurrences and/or metastases,in the patients with relapsing and/or metastatic rectal cancer than in those with relapsing and/or metastatic colon cancer,and in patients received secondary operation than in those received non-operative treatment.Cox multivariable regression model analysis showed that the treatment modality for recurrence and/or metastasis,the number of recurrence and/or metastasis sites,the invasive depth of primary tumor,and lymph node metastasis were correlated with the long-term survival of patients.Among them,the treatment modality was the most important factor influencing the prognosis.ConclusionsThe recurrence and/or metastasis rate is higher in the patients with rectal cancer than in those with colon cancer,but the prognosis of the former is better than that of the latter.Secondary operation,which is helpful for the long-term survival,is suggested for the patients with relapsing and/or metastatic CRC.

Objective To explore the serum proteomics characteristics of early carcerization of post-hepatitic cirrhosis.MethodsThe serum protein profiles were detected of 62 patients with post-hepatitic cirrhosis and 100 patients with hepatic carcinoma in Ⅰ-Ⅱ stage (T1-2N0M0) and cirrhosis by surface-enhanced laser desorption/ionization-time of flight-mass spectrometry (SELDI-TOF-MS) IMAC30-Cu2+ ProteinChip array (Ciphergen Biosystems Inc.,USA),the distinct proteins were analyzed and a classification tree model was established by using Biomarker Patterns software.The diagnostic efficacy of the model was blindly tested using the serum protein from both groups.ResultsThe serum protein profiles of post-hepatitic cirrhosis and hepatic carcinoma complicating with cirrhosis were analyzed and a classification tree model was established including 4 distinct proteins with different M/Z.In the training mode,the accuracy was 99.4% (161/162) on differential diagnosis to differentiate post-hepatitic cirrhosis and hepatic carcinoma complicating with cirrhosis,the sensitivity and specificity were 99.0% (99/100) and 100.0% (62/62),respectively,on the diagnosis of hepatic carcinoma complicating with cirrhosis.In the testing mode,the accuracy of differential diagnosis was 94.4% (153/162),the sensitivity and specificity were 95.0% (95/100) and 93.5% (58/62) on the diagnosis of hepatic carcinoma complicating with cirrhosis.ConclusionSELDI-TOF-MS ProteinChip technique is of convenient and rapid,and with high sensitivity and specificity on the diagnosis of early carcerization of post-hepatitic cirrhosis.

Objective To search for the specific biomarkers associated with local lymphatic metastasis of colorectal cancer in serum.Methods The serum protein profile of colorectal cancer patients was determined by surface-enhanced laser desorption/ionization time-of-flight mass spectrometry (SELDI-TOF-MS),and the peak values of proteins were identified with the matched software,and then clustered to construct the classification tree model.Seventy colorectal cancer patients with local lymphatic metastasis and 75 patients in matched age and gender without local lymphatic metastasis were assigned as a training set to construct the classification tree model,and 35 colorectal cancer patients with local lymphatic metastasis and 30 patients in matched age and gender without local lymphatic metastasis were assigned as test set to make the independent sample double-blind test.Results Forty-six distinct proteins were identified from the two groups,and the classification tree model formed by 5 proteins (M/Z:3104,3781,5867,7970 and 9290) could be used to identify the two groups with a sensitivity of 94.3% (66/70) and a specificity of 100.0% (75/75).The double-blind test challenged the model with a sensitivity of 91.4% (32/35),a specificity of 96.7% (29/30),and a positive predictive value of 97.0% (32/33),respectively.ConclusionThe constructed classification tree model may distinguish colorectal cancer patients with or without local lymphatic metastasis correctly,and show a great potential for preoperatively screening the colorectal cancer patients with or without local lymphatic metastasis.

Objective To explore and determine the biologic markers for the diagnosis of lung cancer by comparison of proteomics among patients with lung cancer,those with benign lung tumor and healthy people.Methods The serum proteomics patterns of 89 cases of lung cancer,64 cases of benign lung tumor and 68 healthy subjects were read by surface enhanced laser desorption/ionization-time of flight-mass spectrometry (SELDI-TOF-MS) to screen significant differential proteins,and to develop a classification tree model for the diagnosis of lung cancer.Thirty cases of lung cancer,30 cases of benign lung tumor and 30 healthy subjects were randomly selected at the same period and assigned as test groups for double-blind verification of the model.Results Thirty-nine differential proteins were identified from the three groups,and the classification tree model formed by 17 proteins (M/Z:4485,5252,5807,5908,5969,6113,6625,8946,8998,9137,9183,9298,9498,13878,15128,15867 and 16081) could be used to identify lung cancer,benign lung tumor and healthy subjects with an accuracy of 98.2% (217/221),sensitivity of 98.9% (88/89) and specificity of 97.7% (129/132),respectively.The double-blind test challenged the model with a sensitivity of 90.0% (27/30) and specificity of 93.3% (56/60).Conclusion The classification tree model constructed by SELDI-TOF-MS possesses high sensitivity and specificity,and it may be used for rapid diagnosis of lung cancer.

Objective To investigate the method and clinical effect for transplanting auto-fat granules to augment breast. Methods The autologous fat granules were obtained by liposuetion using syringe from the sites with cumulate fat. After repeated wash and purification, they were transplanted into the interspace behind the breast by injection. The quantity of auto-fat granules injected was 50 - 100 ml in each side of breast per transplantation at 3 - 6 months intervals, and the whole course of treatment needed 2 -6 transplantations. Results 91 of 107 cases were followed up from 6 months to 3 years after final transplantation. All of them were satisfied with the postoperative effect, showing per-fect and plump appearance of the breasts. However, small indurations were found sporadically in 13 cases (21 breasts) within 2 -9 months, and calcifications in 8 cases (11 breasts) within 8 - 17 months after the first transplantation. Conclusion Both patients and surgeons are almost satisfied with the re-sults. The transplantation of autologous fat granules for breast augmentation is an effective and practi-cal method but the postoperative effect is influenced by multiple factors. A few of cases present com-plications after transplantation, so more clinical observation should be taken.

Objective To evaluate this disease' s incident trend for Shanxi province through hospital-based statistics. Methods Breast cancer data was obtained from the department of radiology in Shanxi cancer hospital for the period 2005-2007. Results Between 2005 and 2007, the numbers of women who accepted mammography rapidly increased from 533 to 1975. 62 women had been diagnosed as breast cancer in 2005, while this number had reached to 400 in 2007. The proportion of breast malignancies during this three year periods had statistically increased with 11.6 %, 17.8 %, and 20.3 % respectively (P<0.001). The mean age of breast cancer patients was older than benign disease patients (50 vs 42.8, P<0.001). The highest breast cancer age group was those aged 45 to 54 (37.6 %). Left breast cancer was higher than right side (53.4 % vs 46 %). Most histological type was invasive ductal carcinoma (78.95 %). The proportion of invasive lobular carcinoma and duetal carcinoma in situ were 8.7 % and 5.4 % respectively. Conclusion Breast cancer incidence rate has been increased in our city. These results are consistent with previous similar studies. Thus, it is essential to establish population cancer incidence registration and develop clinical data system. This will result in better understanding of cancer incidence trends and benefit in the evaluation of the effective cancer control measures.

Objective To discuss the effeet of nursing intervention in the prevention of psychiatric disorder in patients after coronary artery bypass grafting (CABG). Methods Patients with CABG(202 cases) were divided into the control group (100 cases) and the intervention group (102 cases).The control group received routine treatment and nursing while the intervention group was given systemic nursing intervention.The mental status was evaluated by mini-mental status examination (MMSE). Results The incidence of psychiatric disorder in the intervention group was 4 cases (3.92%),which was statistically lower than those in the control group(16 cases,16.00%). Conclusions Effective nursing intervention combined with effective treatment could prevent and control the psychiatric disorder of patients after CABG.

Objective To analyze the imaging features and follow-up changes of high-resolution CT(HRCT) in Goodpasture syndrome.Methods HRCT imaging features and follow-up findings of 15 cases Goodpasture syndrome confirmed by clinical were analyzed retrospectrively.The imaging features included extent,forms and follow-up changes.Results The lung lesion of Goodpasture syndrome involved two lobes(n=1), three lobes(n=2), four lobes(n=5) and five lobes (n=7).Upper lobe of the right lung was the most common involved region.Centered on the hilum of lung consolidations confused ground glass opacity (GGO) were showed in 7 cases, GGO distribution of pulmonary leaflets in 5 cases.On follow-up observation, lobar or segmental consolidation could change into GGO,GGO could disappear in short times.Conclusion Multiple lobar or segmental consolidations confused GGO without the lung bottom and periphery involvement is the imaging characteristics of Goodpasture syndrome patients with anemia and hemoptysis.HRCT is a helpful method for the diagnosis and following up of Goodpasture syndrome.

Purpose To investigate CT and MRI manifestations of renal cell carcinoma associated with Xp11.2 translocation/TFE3 gene fusions (abbreviation as Xp11.2 translocation renal cell carcinoma).Materials and Methods Eighteen cases of Xp11.2 translocation renal cell carcinoma confirmed by pathology were retrospectively analyzed.Ten patients underwent CT scans,2 of them had unenhanced CT and 8 of them had pre-and post-contrast CT scan.Fourteen cases underwent plain and multi-phase contrast MRI scan,including 2 cases with unenhanced CT and 4 cases with pre-and post-contrast CT scan.The location,size,shape,density/signal,blood supply and the enhancement of the Xpl 1.2 translocation renal cell carcinoma were analyzed.Results All of the 18 tumors located in the corticomedullary with 17 solid lesions and 1 cystic lesion.The mean maximum diameter of the tumor was (4.6±2.0) cm.Thirteen lesions were circular or oval and 5 were irregularly or lobulated lesions.Ten lesions showed slightly high or high density on unenhanced CT,and the average CT value was (50.6± 11.5) HU,in which 4 lesions showed calcification.Among 8 cases of enhanced CT,1 lesion showed abundant blood supply,while 7 lesions showed lack of blood supply.Fourteen cases of MRI scan exhibited various imaging features with short T1 and T2 signal,and the persistent enhancement in the medullary phase.The MRI findings were further divided into 3 types according to the signal intensity and blood supply except 1 cystic lesion:① 5 lesions predominantly with short T1 and T2 signal were lack of blood supply;② 4 lesions predominantly with slightly longer T1 and T2 signal were abundant blood supply;③ 4 lesions predominantly with equal T1 and T2 signal were relatively lack of blood supply.Conclusion The CT and MRI features of Xpl 1.2 translocation renal cell carcinoma had certain manifestations:slightly high or high density nodule or mass located in corticomedullary on pre-contrast CT scan,various signal intensity with short T1 and T2 signal on MRI,and the persistent enhancement in the medullary phase.These image features combined with clinical data are helpful for diagnosis.
