Objective To study the significance of anti-antibody of liver antigens in the diagnosis of autoim- mune hepatitis disease.Methods Patients were divided into three groups according the diseases:autoimmune hepatic disease 45 cases including autoimmune hepatitis(AIH)15 cases,primary biliary cirrhosis(PBC)20 cases,and prima- ry sclerotic cholangitis(PSC)10 cases;Various virus hepatitis 50 cases;Liver damage of unknown cause 30 cases.Au- to-antibody of liver antigens SLA/LP,LKM-1,LC-1,and AMA-M2 were identified by indirect immunofluorescence (IIF)assay and immunoblot assay.Results The positive rates of anti-SLA/LP(46.6%)was significantly higher than those of anti-LKM-1(13.3%),anti-LC-1(0%),and anti-AMA-M2(13.3%)in patients with AIR while these four antibodies were negative in patients with virus hepatitis.The positive rates of anti-AMA-M2 in patients of PBC and unknown liver damage were 95.0% and 6.6%,respectively.Conclusion Anti-SLA/LP is a new specific serum marker in diagnosis of AIR.The auto-antibody detection of liver antigens will be helpful to the diagnosis and therapy of autoimmune hepatic disease.

Identification and validation of a new target is one of the most important steps for new antituberculosis (TB) drug discovery. Researches have shown that Mycobacterium tuberculosis (Mtb) encodes 20 CYP450 enzymes which play important roles in the synthesis and metabolism of lipid, cholesterol utilization, and the electron transport of respiratory chain in Mtb. With the critical roles within the organism as well as the protein structures of six Mtb CYP450 enzymes being clarified, some of them have been highlighted as potential anti-tuberculosis targets. In this paper, the phylogenetic analysis, the structural features, and the enzymatic functions of Mtb CYPs, as well as the mechanism of interactions with selective inhibitors such as azole antifungal agents for the CYPs have been reviewed and summarized. The druggability of the CYPs has also been analyzed for their further utility as targets in high throughput screening and rational design of more selective inhibitors.

A 56-year-old man with 1-year history of palpitation, heat intolerance and sweating, was diagnosed as thyrotropin (TSH) -secreting pituitary adenoma based on the symptoms of hypermetabolism, enlarged thyroid gland, inappropriately increased serum TSH concomitantly elevated plasma thyroid hormones and a pituitary tumor demonstrated on magnetic resonance imaging. Long-acting octreotide formulation was administered at a dose of 20 mg intramuscularly. Tumor volume shrinkage and improvement of thyroid function was achieved after a single drug injection; and the thyroid function returned to normal in 28 days. It is suggested that long-acting octreotide formulation might be used as a routine therapeutic approach prior to pituitary surgery, which may enhance the effectiveness of surgery and postoperative recovery.

Objective To evaluate effect of en bloc resection of malignant sacral tumor involving partial sacrum and ipsilateral sacroiliac joint with reservation of contralateral sacral foramina.Methods Between February 2005 and July 2010,16 patients with malignant sacral tumor involving partial sacrum and ipsilateral sacroiliac joint underwent hemi-sacrectomy and functional reconstruction.The operation achieved en bloc resection of tumor with reservation of contralateral sacral foramina.There were 10 males and 6 females,aged from 17 to 70 years (average,37.9 years).There were 5 cases of chondrosarcoma,3 cases of Ewing's sarcoma,2 cases of malignant schwannoma,2 cases of osteosarcoma,1 case of malignant giant cell tumor of bone,1 case of lymphoma and 2 cases of metastatic tumor.Results The surgical time ranged from 4 to 11.5 hours (average,6.5 hours).The average blood loss was 3600 ml (range,1500 to 5500 ml).Five patients underwent type Ⅰ resection,while 11 patients underwent type Ⅱ resection.All patients were followed up for 21 to 59 months (average,34.4 months).Three months after operation,13 patients had difficulty with ankle plantar flexion,while sphincter function was more or less reserved in 16 patients.Four patients (25％)had wound healing complications,which was cured after debridement and drainage.Local recurrence occurred in 7 patients.There were 5 cases of local recurrence among 6 patients who had intralesional margin;4 recurrence lesions located in the sacrum and 1 in soft tissue.Eight patients (50.0％) survived without tumor,2 patients (12.5％)survived with tumor,and 6 patients (37.5％) died of tumor.Conclusion The en bloc resection of tumor involving partial sacrum and ipsilateral sacroiliac joint with reservation of contralateral sacral foramina was feasible and had better outcome compared with total sacrectomy.

Artemisia lactiflora is an important medicinal plant in China. The antitumor and antioxidant activities of the extracts of 54 endophytic fungi from the plant were screened via MTT assay and DPPH scavenging radical assay, respectively. The bioactive strains were identified based on similarity of 5.8S gene and internal transcribed spacer (ITS) sequences. The results showed that extracts from ten (18.5%) isolates exhibited antitumor activity, and which from two (3.7%) isolates exhibited antioxidant activity. The Alternaria sp. GYBH47 strain was simultaneously having antagonistic activity against HL-60 leukemia, MCF-7 breast and COLO205 colon cell lines, and Phomopsis sp. GYBH42 strain having cytotoxic and antioxidant activities. The results indicated that endophytic fungi from Artemisia lactiflora are potential resources to find valuable bioactive components.

Objective:To explore and analyze the points-selection rules in acupuncture treatment of mammary gland hyperplasia (MGH) by data mining and statistical method. Methods:Clinical literatures about the treatment of MGH with acupuncture published in the recent 16 years were retrieved from Chinese Journal Full-text Database (CJFD) and established into a database by Excel. The SPSS 20 version software and Clementine 12.0 version software were adopted to analyze the frequency and association rules of points-selection in the treatment of MGH with acupuncture. Results:The top 3 points used most frequently in acupuncture treatment of MGH were Danzhong (CV 17), Taichong (LR 3) and Zusanli (ST 36); points from the Stomach Meridian of Foot Yangming and Liver Meridian of Foot Jueyin were most commonly used; the commonly selected points were predominantly distributed in thoracic and abdominal regions and lower limbs; emphasis on the combination use of local and distal points; of the specific points, the five Shu-Transmitting points were mostly used; association analysis showed that the associations among Taichong (LR 3), Danzhong (CV 17) and Zusanli (ST 36) were the most significant. Conclusion: The data mining results substantially accord with the general rules of acupuncture-moxibustion theories in traditional Chinese medicine, able to reflect the points-selection principles and features in acupuncture treatment of MGH and provide evidence for the points selection in the treatment of MGH in acupuncture clinic.
