There are many factors that result in postoperative dyslipidemia. However, the factors influencing serum lipid levels are changing with the development of organ transplantation. In this article the effects of different anti-rejection drugs such as cyclosporine, azathioprine, mycophenolate mofetil, tacrolimus, rapamycin ( sirolimus ) , corticosteroids, and monoclonal antibody on dyslipidemia after organ transplantation were summarized in different eras.

Objective To evaluate septin-9 and clusterin protein levels in the peripheral blood samples from epithelial ovarian cancer patients, and explore its clinical significance. Methods Clinical data of 200 patients in Cancer Hospital,Chinese Academy of Medical Sciences from Jan. 29, 2008 to Feb. 1,2010 were collected. The peripheral blood samples were obtained from 137 epithelial ovarian cancer patients, 12 borderline ovarian tumor patients, 10 benign ovarian tumor patients, 41 benign pelvic lesion patients and 58 healthy women. The septin-9 and clusterin protein levels in the plasma were measured by double antibody sandwich ELISA or ELISA. The clinical significance of clusterin and septin-9 in plasma was analyzed. The diagnostic efficacy of septin-9 and clusterin protein in the detection of ovarian cancer was evaluated by the area under the curve (AUC) of the receiver operating characteristic (ROC) curve. Results Double antibody sandwich ELISA showed: the mean levels of plasma septin-9 in epithelial ovarian cancer patients or benign pelvic lesion patients were significantly higher than that in healthy women detedted by double antibody sandwich ELISA (P<0.01). The mean levels of plasma septin-9 in epithelial ovarian carcinoma patients with tumor family history or distance metastasis were significantly higher than those patients without (P<0.05). While the expression level of septin-9 protein in peripheral blood of ovarian cancer patients was not related to the patient age, pathologic stage, pathologic differentiation, smoking history, treatment history (including surgery, radiotherapy and chemotherapy) and lymph node metastasis (all P>0.05). ELISA showed: the mean level of plasma clusterin in epithelial ovarian cancer patients was significantly higher than that in healthy women deteded by ELISA (P=0.021). The expression level of clusterin protein in peripheral blood of ovarian cancer patients was not related to the above clinical pathological parameters (all P>0.05). To distinguish between ovarian cancer patients and healthy women by septin-9 protein expression level in plasma, when AUC was 0.712 and cut off was 0.28, the sensitivity of detection ovarian cancer by septin-9 protein expression was 82.5%, and the specificity was 50.0%. To distinguish between ovarian cancer patients and healthy women by clusterin protein expression level in plasma, when AUC was 0.636 and cut off was 87.96 pg/L, the sensitivity of detection ovarian cancer by clusterin protein expression was 71.5%, and the specificity was 41.4%. Conclusions The expression of septin-9 and clusterin protein in peripheral blood of ovarian cancer patients is increased, especially the expression level of septin-9 protein with related to the distant metastasis. The study results shown that the detection of septin-9 and clusterin in plasma has a certain diagnosis value in ovarian cancer, which may be a potential markers for ovarian cancer.

Objective To investigate the morphology,size and density characteristics of adult normal thyroid and to establish the normal reference range of thyroid.Methods 317 patients without thyroid disease underwent head and neck computed tomography angiography (CTA)examination from Jun.2011 to Jun.2012 in the First Affiliated Hospital of Chongqing Medical University.Their data were analyzed.The thyroid morphology including the outside angle,width,thickness,isthmus was observed and measured.Plain scan and arterial phase CT values of thyroid gland were measured.The age and sex of patients were recorded.The left and right lobe on the thyroid dimension and density were investigated,and the index 95％ normal reference range was calculated.Results ① Morphology:normal thyroid glands were butterfly-shaped on the axis,accounting for 95.9％(304/317),and absence of thyroid gland isthmus accounted for 4.1％(13/317).② There was no significant difference for the thyroid lateral angle between the lobes and sexes(P＞0.05).There was significant difference between age groups(P=0.00).The 95％ reference range:the outside angle was 111.7°± 31.6° in patients younger than 60 years old,and 101.3°± 36.7° in patients of or older than 60 years old.③ The dimensions of the right lobe were longer than those of the left.The dimensions of the lobes in males were longer than those in females.There was no statistical difference among decades(P＞ 0.05).There was no significant difference in the thickness of thyroid isthmus between genders and among different age groups (P＞ 0.05).95％ reference range of the thickness of thyroid isthmus was 1.1-7.3 mm.④ There was statistical difference for the plain scan and enhanced CT values between lobes and sexes and among age groups (P＜0.05).95％ reference range needed to be separately formulated between the lobes,sex and age＜30 years and ≥30 years.Conclusion Studying the morphology,size and density characteristics of adult normal thyroids can help to establish normal thyroid imaging anatomical data in this region,and provide reference basis for imaging diagnosis of thyroid disease.

Objective To investigate the effects of exogenous glial cell derived neurotrophic factor (GDNF)on colon glial cells in slow transit constipation (STC ) rats,and to explore the optimal concentration of GDNF in order to provide evidence for intestinal neurotrophic therapy in the treatment of STC.Methods A total of 132 SD rats were divided into STC group and control group,66 rats in each group.STC rats were established by feeding with rhubarb.Six rats were randomly selected from either groups to verify whether STC model was successfully established.And the left 120 rats of two groups were randomly divided into six subgroups:STC group one to group six and control group one to group six,ten rats in each group,which were untreated,injected through tail vein with saline,and 0.001 ,0.010, 0.050,0.100 μg/L GDNF 2 mL respectively for one week.The expression of Sox-8 at protein level of either group were detected by Western blotting.Independent sample t test was performed for statistical analysis.Results After treated with 0.001 μg/L GDNF (STC group three),there was no significant
difference in expression level of Sox-8 between STC group three and STC group one (13.38 ±0.70 vs 13.39±0.45 ,t = 0.042,P = 0.969 ).After treated with 0.010 μg/L GDNF (STC group four),the difference in expression level of Sox-8 between STC group four and STC group three was significant (21 .11 ±2.56 vs 13.38±0.70,t=5 .040,P <0.01).After treated with 0.050 μg/mL GDNF (STC group five),the expression level of Sox-8 was higher than that in STC group four (31.86±1.57 vs 21.11±2.56,t=-6.198,P <0.01 ).The Sox-8 expression of untreated,saline treated,0.001 and 0.050 μg/L GDNF treated STC rats (STC group one,two,three and five)were lower than those of the corresponding control groups (t= 3.394,12.103,10.302,- 6.120,all P < 0.05 ).Conclusion Exogenous GDNF could increase Sox-8 expression in colon tissue of STC rats,an increase in the number of colon glial cells could repair enteric nervous system,and 0.050 μg/L was the optimal concentration.

Objective To compare the efficacy of stents 7 F and 10 F in drainage of pancreatic pseudocyst via EUS-FNA.Methods A retrospective analysis of patients with pancreatic pseudocyst who received endoscopic ultrasonography guided puncture drainage by using 7 F and 10 F double pigtail plastic stent respectively in Drum Tower Hospital of Nanjing University Medical School from 2010 to 2014 was conducted.Patients' hospitalization period, the time for 50％ cyst reduction, removal time, infection rate, and recurrence rate were compared.Results Twenty three patients with pancreatic pseudocyst were included, among whom 14 were male and 9 were female.The age ranged from 13 to 70 with an average of 45.1 years.Eleven patients were treated with 7 F pigtail plastic stents whereas 12 patients with 10 F pigtail plastic stents.All patients were treated with additional 8.5 F joint nose cyst drainage.Four cases in 7 F group got fever, 3 of whom were successful in anti-infection and 1 failed, having to change the stent.One case (9.1％) relapsed without symptoms after 52 months during the follow-up and received no intervention.Five cases in 10 F group got fever, 4 of whom were successful in anti-infection and 1 failed, having to change the stent.One case (8.3％) was identified as mild hemorrhage, and replantation needed to be performed in 1 case (8.3％) because stent was found to slip after 12 days.Two cases (16.7％) relapsed without symptoms after 11 and 24 months respectively and no intervention was received.There was no significant difference in patients' age, cyst size, removal time, infection rate and recurrence rate between the two groups.However, patients in group 10 F had a markedly shorter hospitalization period and time for cyst reduction by at least 50％ than those in group 7 F (P ＜ 0.05).Conclusion 10 F double pigtail plastic stents can drain the cyst faster, shorten the hospital stay, but there is no significant difference in infection or recurrence rate of cyst compared with 7 F stents.

Objective To analyze the clinical features of patients with IgG4-associated biliary and pancreatic diseases,and to improve the understanding of these diseases.Methods Nine cases of patients with IgG4-associated pancreatitis and cholangitis were analyzed retrospectively,which included clinical manifestations,serological examination,imaging test,pathology,treatment and prognosis.Results Of the 9 patients,8 were male,1 was female,the average age was 61 years old.Four cases were presented with jaundice,2 cases with jaundice and abdominal pain,2 cases with abdominal pain,and 1 case with diabetes.Serum IgG4 levels were 3.46-21.3 g/L (mean 9.743 g/L) in 6 cases,and which were higher than normal value,3 patients did not undergo blood test of IgG4.Nineteen auto-antibodies (including ANCA) were all negative in 9 cases.CA19-9 was increased in 4 cases.CT manifestations showed 5 cases with low density pancreas mass (2 cases with biliary tract dilatation);1 case had pancreas swelling with dilatation of bile duct,and 2 cases with bile duct dilatation only,and CT findings in 1 case were negative.Four patients underwent EUS-FNA,and EUS features included hypoechoic lesions without peripancreatic lymph nodes.FNA results indicated 2 cases with IgG4 related chronic inflammation,2 cases with chronic inflammation with negative IgG4.Seven cases were confirmed to have IgG4 related pancreatitis,and 2 cases with IgG4 related cholangitis.Six patients received glucocorticoid treatment,and the dose ranged from 8-40 mg;3 patients underwent surgery and the surgical pathology indicated IgG4 positive plasma cell.Follow-up showed the serum IgG4 returned to normal,clinical symptoms improved remarkably,and pancreatic mass decreased.Conclusions IgG4 positive plasma cell infiltration is the main feature of IgG4-associated cholangitis and pancreatitis.The diagnosis should combine image,serology with pathology.Glucocorticoid is an effective treatment.

ATP binding cassette transporter A3（ABCA3）is a critical protein involved in phospholipid metabolism in typeⅡ alveolar cells，participating in the synthesis of pulmonary surfactant.Early studies have found that mutations in ABCA3 gene can lead to childhood interstitial lung disease（chILD），but the underlying mechanisms remain unclear.Recent elucidation of the ABCA3 structure，coupled with functional inquiries into the protein，has engendered fresh insights into the intricate mechanisms governing phospholipid metabolism orchestrated by ABCA3，inspiring the development of small molecule drugs targeting ABCA3 gene mutations.This article provides a comprehensive review of the involvement of ABCA3 in phospholipid metabolism，the pathogenic mechanisms of related lung diseases，the genotype-phenotype correlations，and the forefront advances in treatment.Additionally，it underscores lingering unresolved queries，aiming to provide a platform for the future refinement of precision treatments for ABCA3 mutations.
