Adrenocortical carcinoma (ACC) is a rare disease with poor prognosis.Patients usually present with signs of steroid hormone excess (e.g.Cushing's syndrome, Conn's syndrome, virilization) or an abdominal mass.In functional cases, Cushing's syndrome is the most frequent presentation.Mitotane is still the most important single drug for ACC treatment, and it plays a role in adjuvant therapy postoperatively as well as in advanced disease.In advanced ACC, a combination of mitotane with etoposide, doxorubicin, cisplatin or streptozotocin with mitotane may be used.Targeted therapies, such as insulin-like growth factor Ⅰ (IGF- Ⅰ)receptor inhibitor and multiple kinase inhibitors like sunitinib and sorafenib hold great promises.

Purpose To describe the clinical and pathological features of atypical vascular lesions (AVLs) after conservative surgery and radiation of the breast cancer,and to discuss the association with post-radiation angiosarcoma.Methods The clinical and pathological features in one case of AVLs was evaluated.The literatures were reviewed.Results The patient is a 57-yeAR~-old female who underwent a conservative surgery of the right breast because of a carcinoma.She received standard dose of radiation as adjuvant therapy.Three years later, multiple erythematous plaques developed around the former scar, which radiated to the nipple.Clinically,the plaques were considered as relapses of the carcinoma.However, fine needle aspiration gave negative results.Biopsy of one large plague revealed a circumscribed vascular lesion confined to the superficial dermis.It was composed of thin-walled anastomosing lymphatic vessels lined by attenuated endothelial cells.In focal areas, the vessels extended to the mid-dermis.Immunohistochemically, the endothelial cells were positive for CD31, CD34 and D2-40,with absent of α-SMA positive pericytes.Review of the breast tumor sections showed an invasive micropapillary carcinoma.Conclusions AVLs is a rare vascular lesion related with conservative surgery and post-radiation therapy of the breast.AVLs may represent as a precursor of breast angiosarcoma.Being familiar with the clinicopathologic characteristics of AVLs is important not only for the pathologists but also for the clinicians.

Stilbene glucoside is one of major active constitutions in Polygoni Multiflori Radix. Stilbene glucoside contributed markedly to resisting caducity, protecting nerve, reducing serum lipids, and protecting liver and antitumor activity. The extraction and purification technology is the key issue to obtain stilbene glucoside. Through research, extraction and purification technology has made a certain progress. The stilbene glycoside could be extracted by water boiling, diacolation, and backflow; then it could be purified by the method of chromatography, recrystallization, and extraction. In this article, the technologies in extracting and purifying stilbene glucoside were reviewed, and the prospect of stilbene glucoside preparation was discussed to lay the foundation for further research and application.

ObjectiveTo retrospectively analyse the data of patients with suspected primary aldosteronism (PA) during the last five years.The receiver operating characteristic (ROC) curve was used to evaluate the value of aldosterone to renin ratio (ARR) in screening primary aldosteronism.MethodsThe clinical data of ARR in supine and upright positions were collected in 590 patients with suspected during January 2006 to August 2010.There were 357 patients diagnosed as primary aldosteronism and 233 patients as essential hypertension among these patients.100 patients with suspected primary aldosteronism took the upright and random ARR during September 2010 to April 2011 ; Among these patients,29 patients were diagnosed as primary aldosteronism and 71 as cases of essential hypertension.ROC curve was made to retrospectively define the method and the cut-off value of the supine,upright or random ARR.ResultsThe area under the curve(AUC) of the supine ARR in the 590 patients who took the supine and upright ARR during January 2006 to August 2010 was 0.838 (0.805-0.867 ) and the AUC of the upright ARR was 0.873 (0.843-0.899 ).There was significant difference between these two AUC readings (P＜0.01 ).The AUC in the upright ARR of the 100 patients who took the upright and random ARR during Septeuder 2010 to April 2011 was 0.962 (0.928 -0.995 ) and the AUC of the random ARR was 0.944 (0.893-0.994 ).There was no significant difference between these two AUC readings (P＞0.05).The upright ARR cutoff value with 400 ( pg · ml-1 )/( ng· ml-1 · h 1 ) yielded a sensitivity of 91.9％ and a specificity of 64.2％ to diagnosis of PA.ConclusionUpright ARR value was more suitable in the screening test than supine ARR value.Random ARR showed similar effect as the upright ARR.In our research,under strict control of the drug,position and detection time,ARR value with 400 ( pg · ml-1 )/( ng· ml-1 · h-1 ) can be the cutoff point in screening the suspcctcd PA patients.

Objective To compare the clinical efficacy between standard sequential early enteral nutrition (EEN) plus parenteral nutrition (PN) and PN alone in patients undergoing gastrointestinal surgery. Methods Werandomly divided 126 patients who underwent laparotomy gastrointestinal surgery into EEN + PN group (n = 62) and PN group (n = 64). The levels of blood nutrition-related indicators, biochemical indicators, and inflammatory indicators were determined before surgery and 3 and 7 days after surgery, and the gastrointestinal function recovery time, complications, nutritional support cost, and length of hospital stay were compared between two groups. Results The preoperative nutrition-related indicators, biochemical indicators, and inflammatory indicators showed no significant differences between two groups (P >0. 05). Three days after operation, however, the levels of prealbumin in EEN + PN group were significantly higher than those in PN group [(160. 3 ±23. 0) g/L vs. (137.0±28.7) g/L, P=0.000]. Seven days after operation, the levels of albumin [(33.6±3.8) g/L vs. (31.8±4.7) g/L, P = 0.042], prealbumin [(210.6±34.6) g/L vs. (154.8 ±36.9) g/L, P=0.000], and lymphocyte cell count [(2.33±0.53) x 109/L vs. (1.04±0.36) × 109/L, P = 0. 046] in EEN + PN group were significantly higher than those in PN group, and the levels of serum γ-glutamyltransferase [(48. 12 ± 33.84) U/L vs. (71.54±34.00)U/L, P=0.048], C-reactive protein [(31.15 ± 19.00) mmol/L vs. (45.90 ± 23.21) mmol/L, P=0.042], total cholesterol [(3.09±0.83) mmol/L vs. (3.29±0.91) mmol/L, P = 0. 045] and low density lipoprotein [(2.01 ± 0. 39) mmol/L vs. (2. 31 ± 0. 72 ) mmol/L, P = 0. 049] were significantly lower than those in PN group. The postoperative gastrointestinal function recovery time in EEN + PN group was significantly shorter than that in PN group [(65. 7 ± 15. 6) hours vs. (75. 1 ± 27. 0) hours, P = 0. 036], and the total cost of perioperative nutrition in EEN + PN group was also significantly lower than in PN [(2634. 5 ±1306. 8) RMB vs. (3058. 6 ± 1216. 0) RMB, P= 0.046]. Conclusion Standard sequential EEN plus PN can increase the post-operative prealbumin level, improve the immune function, promote the recovery of gastrointestinal function, and decrease the cost of nutritional support.

Objective:To investigate the clinical manifestations, laboratory and imaging features, treatment and prognosis of systemic lupus erythematosus (SLE) with primary sclerosing cholangitis (PSC).Methods:This is a retrospective case series study describing the clinical, laboratory and imaging manife-stations, treatment and prognosis of 3 SLE patients with PSC. The related literatures were reviewed.Results:In total, 10 patients were included. SLE with PSC, with an average age of (43±17) years old, was more common with hematological and renal involvement, jaundice and arthralgia, positive anti-double-stranded DNA (anti-dsDNA) antibody, hypocomplementemia, elevated erythrocyte sedimentation rate (ESR) and abnormal liver function with predominately elevated alkaline phosphatase (ALP). The classic magnetic resonance cholangio-pancreatography (MRCP) features of PSC include multifocal strictures, beading and areas of dilatation involving the intra- and/or extrahepatic bile ducts. The treatment included glucocorticosteroids, immunosup-pressants and ursodeoxycholic acid (UDCA), and some patients required biliary drainage. Most patients had a good prognosis.Conclusion:Although PSC is rare, attention should be paid to SLE patients with abnormal liver function, especially with elevated ALP, in order to differentiate from PSC.

Objective:To study the protective effects of sea buckthorn polysaccharide extracts on lipopolysaccharide( LPS)/D-galactosa mine ( D-GalN )-induced liver injury in mice and investigate the regulation on hepatic TLR4 and SOCS3 expression.Methods:C57BL/6 male mice were randomly divided into six groups:control group,model group,dexamethasone positive control group, low, medium and high dose group of sea buckthorn polysaccharide.Mice in the sea buckthorn polysaccharides low, medium and high dose group were gavaged with 50, 100 and 200 mg/kg sea buckthorn polysaccharide extracts for 14 days respectively.Acute liver injury model were established by intraperitoneal injection of LPS(10 μg/kg) and D-GalN (700 mg/kg).The mice in the dexamethasone positive control group were intraperitoneally injected with dexamethasone (10 mg/kg) before model estab-lishment.Serum and liver samples were collected after model establishment for 4 h .Serum levels of ALT and AST were detected.Histological changes of liver tissue were observed by HE staining.Hepatic expression of TLR4 and SOCS3 was detected by Western blot.Results:Sea buckthorn polysaccharide significantly inhibited LPS/D-GalN-induced elevation in serum levels of ALT and AST.It also alleviated liver cell injury and inflammatory infiltration.Western blot results showed that sea buckthorn polysaccharide inhibited LPS/D-GalN-induced TLR4 expression.SOCS3 expression was not dramatically influenced by sea buckthorn polysaccharide supplementation.Conclusion:Sea buckthorn polysaccharide protects against LPS/D-GalN-induced liver injury.This protective effects may be achieved by inhibiting the expression of TLR4 but not associated with modulation on SOCS3 expression.

Objective:Using the macrophage cell lines RAW264.7 stably expressing Rab5a and its dominant negative mutant Rab5aN133I as models to analyze the effect and the mechanism of Rab 5a,Rab5aN133I on CpG-induced production of pro-inflammatory cytokines and type Ⅰ IFN.Methods: The eukaryotic expression vectors of Rab5a and Rab5aN133I were transfected into RAW264.7 cells by liposome,and screened with G418.The G418-resistant colonies were obtained and amplified.The transformed cell lines were i-dentified by RT-PCR,Real time-PCR and Western blot.The production of cytokines were measured after transformed cell lines of Rab5a and Rab5aN133I was stimulation with CpG for 8 h.Results: Rab5a expression in transfected cells was significantly higher than the control cell group (P<0.05).Overexpression of Rab5a significantly promoted the production of TNF -α,IL1-β(P<0.01) and IFN-β( P<0.05) in CpG stimulated RAW264.7.The production of cytokines was restored in Rab 5aN133I transfected cell line.Conclusion:Rab 5a promotes CpG-induced pro-inflammatory cytokines and typeⅠIFN in macrophages,it may be act as a positive regulator in TLR9 signaling pathway.

Objective To explore the efficacy of pulse infusion of gonadorelin (LHRH) on the patients with idiopathic hypogonadotropic hypogonadism (IHH) via a micro infusion pump. Methods The protocol was designed as an open, self-controlled prospective study. 31 patients were enrolled and assigned to 3 groups: 23 males without gonadotropin-releasing hormone ( GnRH ) pulse ( group A), 2 males with GnRH pulse frequency insufficiency ( group B), and 6 females ( group C). All the subjects were admitted LHRH every 90 min via the micro infusion pump for 24 weeks. Sex hormones and related characteristics were compared before and after the treatment. Results After 24-weeks treatment, LH peak value reached ( 6. 92 ±5.66 ), ( 9. 55 ±0. 98 ), and ( 6. 93 ±4. 52 ) IU/L; and FSH peak value reached ( 7.44 ± 3. 80 ), ( 12. 85 ± 12. 80 ), and ( 7.38 ±4. 98 ) IU/L among 3 groups, respectively. The testosterone also reached ( 3.18± 1.81 ) and ( 5.78±4. 65 ) ng/ml in groups A and B ( all P＜0. 01 ). In groups A and B, the testis volumes were increased, seminal fluid production was found in 7 patients and spermatogenesis in 6 patients. In group C, uterus was enlarged 85.4%, as well as the ovaries of both sides. Menarche was reported in 5 patients. 19. 4% of the studied patients complained uncomfortable at the injection sites, all the symptoms were mild. Conclusion Pulse infusion of LHRH in IHH patients via a micro infusion pump is effective, while the medication system needs improving.
