Objective To evaluate the value of Microparticle Enzyme Immunoassay(MEIA),a quantitative assay, in the diagnosis and treatment of chronic hepatitis B (CHB). Methods MEIA, Enzyme linked immunoabsorbent assay (ELISA), and quantitative PCR were used to detect e antigen, hepatitis B serum markers, and the quantity of HBV DNA in 249 CHB patients and 32 non CHB patients respectively. Expression of HBcAg in Liver tissue was detected by using S P method. These measures were used to illuminate the relationships among serum e antigen quantity, hepatitis B serum markers, the quantity of HBV DNA, the quantity of HBcAg in hepatocytes, and pathologic diagnosis of liver tissues. Results 1. The sensitivity of MEIA (80.28%) to detect serum e antigen is higher than that of ELISA (69.01%)( ? 2=9.312, P =0.002).2. The serum e antigen quantity is positively correlated with the logarithm of the quantity of HBV DNA ( r =0.411, P =0.000). 3. The level of serum e antigen is positively correlated with the semi quantitative of HBcAg in hepatocytes ( r =0.646, P =0.000). 4. The serum e antigen quantity is negatively correlated with pathologic degree of liver tissues ( r =-0.172, P =0.006). Conclusions MEIA is a sensitive, stable, and reliable method to assay the serum e antigen quantity which could be used to evaluate the replication of HBV and the degree of liver damage.

Objective To study the clinical features,treatment and prognosis of struma ovarii.Methods From January 1990 to January 2012,a total of 68 patients were diagnosed struma ovarii at the Department of Obstetrics and Gynecology,Peking Union Medical College Hospital.Clinical data of these patients were studied retrospectively.Results (1) Characteristics of patients:the median age of patients was 42 years old (17-81 years).Of those patients,64 cases (94％) were diagnosed begin struma ovarii and 4(6％) were malignant struma ovarii.(2) Clinical feature:32(47％,32/68) patients were identified with pelvic mass by ultrasonic test,28 cases(41％) had clinical abdominal pain,8(12％) touched a mass from abdominal wall.Preoperative CA125 were tested in 54 patients,but only 8 cases(15％) had moderate elevation.All patients receive ultrasound examination,and 51 cases (75％) were mulitcystic lesions with many septi,3(4％) solid lesions and 14(21％) solid-cystic tumors.The mean diameter of tumors was(8 ± 3) cm.Ascites was present in 4 (6％,4/68)patients.Sixty-seven patients had unilateral lesions,and 1 patient had bilateral lesions.No patient had hyperthyroidism presentation.Nineteen cases underwent thyroid function test after operation,and the results were normal.(3) Treatment:all patients underwent surgical treatment.Among patients with begin struma ovarii,25 cases underwent cystectomy,15 cases unilateral,2 bilateral salpingo-oophorectomy,22 cases hysterectomy + unilateral or bilateral salpingo-oophorectomy.Four malignant struma ovarii,1 patient underwent fertility-sparing staging surgery,2 patients unilateral salpingo-oophorectomy,1 case hysterectomy + bilateral salpingo-oophorectomy.Two patients received chemotherapy after surgery.(4) Prognosis:all patients were followed up in Peking Union Medical College Hospital.The median follow-up time of benign struma ovarii was 5.4 years (6 months-21 years) and there were no recurrence.The median follow-up time of malignant struma ovarii was 11.5 years (9-20 years).Three cases had long-term recurrence at 2,7 and 16 years respectively after surgery.They were received surgical treatment after recurrence and all were alive.Two cases were given by thyroidectomy and 131I treatment.Conclusions Struma ovarii is a rare ovarian monodermal teratoma.Tumorectomy or salpingo-oophorectomy is the appropriate therapeutic treatment for benign struma ovarii.The incidence of malignant struma ovarii is low,and there are no standard treatments.Because of higher long-term recurrence rate,these patients need close follow-up.

Objective To analyze the correlation of preoperative serum vascular endothelial growth factor(VEGF)level with serum CA125 level in patients with epithelial ovarian cancer(EOC),and to evaluate the prognostic value of preoperative serum VEGF in these patients.Methods Forty-one patients with EOC were included as study group,while 20 healthy women were selected as control group.Enzymelinked immunosorbent assay(ELISA)and chemiluminescence assay were used to measure serum VEGF and CA125 level respectively.The correlations of serum VEGF with CA125 level,postoperative recurrence rate and survival time were analyzed retrospectively.Resuits Serum VEGF levels in patients with EOC were higher than those in healthy women,with the median of 415 and 165 ng/L,range 110-2120 and 100-735 ng/L respectively(P＜0.01).No correlation was found between preoperative serum VEGF and CA125 level (Spearman test,P=0.989).High preoperative serum VEGF was positively correlated with postoperative recurrence.Serum VEGF level in patients with postoperative recurrence was higher than that in patients without recurrence,with the median of 490 and 315 ng/L respectively(P=0.035).Univariate analysis showed that higher serum level was reversely correlated with shorter survival.Median overall survival time in patients with higher serum VEGF level and lower serum VEGF level was 18 months and＞35 months respectively(P=0.010).Multivariate Cox model analysis showed that high VEGF level was an independentfactor for the prognosis of EOC(P=0.042).Conclusion Preoperative serum VEGF level is not correlated with CA125 concentration in patients with EOC,and it is an independent risk factor for prognosis.

Objective To explore the prevalence and clinical significance of metabolic disorder of lipids, glucose and uric acid at different fibrosis stages of patients with chronic hepatitis B (CHB).Methods From January 2006 to December 2014, 1 812 CHB patients in Department of Infectious Diseases, Shunde Hospital of Southern Medical University were retrospectively enrolled and analyzed.All biochemistry indexes were obtained by automatic biochemical instrument.Polymerase chain reaction was used for detecting serum hepatitis B virus (HBV) DNA, and particles immune detection kit was used for detecting hepatitis B e antigen (HBeAg).In statistical analyses, chi-square test, nonparametric test and Logistic analysis were used.Results The metabolic disorder prevalence in 1 812 CHB patients was as follows, 455 cases (25.1%) with decreased high density lipoprotein, 435 cases (24.0%) with increased uric acid, 342 cases (18.9%) with increased total cholesterol, 254 cases (14.0%) with increased triglyceride, 171 cases (9.4%) with decreased apolipoprotein A, 165 cases (9.1%) with increased apolipoprotein B, 162 cases (8.9%) with increased low density lipoprotein and 117 cases (6.5%) increased fasting blood glucose.Patients who had mild liver fibrosis tended to have metabolic disorders of uric acid (26.4%), total cholesterol (22.8%) and high density lipoprotein cholesterol (20.5%).Patients who had moderate liver fibrosis tended to have metabolic disorders of high density lipoprotein (27.2%) and uric acid (20.9%).Patients who had severe liver fibrosis tended to have metabolic disorders of high density lipoprotein (33.6%) and uric acid (22.2%).Multivariate Logistic regression analysis showed that inflammation activty (OR=17.31, 95% CI: 13.410-22.336, P=0.001), age (OR=1.019, 95%CI:1.005-1.035, P=0.010), sex (OR=1.497, 95% CI: 1.061-2.111, P=0.022), apolipoprotein A (OR=0.50, 95% CI: 0.281-0.892, P=0.019) and HBV DNA (OR=0.904, 95% CI: 0.858-0.952, P=0.001) may be independent predictors of moderate and severe liver fibrosis.Conclusions CHB patients with mild liver fibrosis tend to have metabolic disorders of uric acid, total cholesterol and high density lipoprotein cholesterol;patients with moderate liver fibrosis tend to have metabolic disorders of high density lipoprotein and uric acid;and patients with severe liver fibrosis tend to have metabolic disorders of high density lipoprotein and uric acid.

6.24 mmol/L) and sixty healthy persons in the health center of our hospital were investigated as hyperhpidemia group (Hyperlipidemias) and control group (Controls) respectively.Hyperlipidemias were given simvastatin 20 mg?d~(-1) for twelve weeks (Statins).Blood samples of ulnar vein were extracted from Statins at the end of twelve weeks as well as Controls and Hyperhpidemias at the beginning of the experiment. Blood serum,plasma and mononuclearcell were extracted and stored at a refrigerator of-80℃.The level of plasma angiotensinⅡwas detected by the method of radioimmunity.While the expression of RANTES mRNA and protein on mononuclearcell were assessed by real time reverse transcription polymerse chain reaction and Western blot respectively.Results①The plasma angiotensinⅡof Hyperlipidemias was higher than that of Controls [(92.13?22.03) vs (50.85?12.12),P

A variety of natural and artificial cryoprotectant extenders have been explored to enhance sperm recovery following cryopreservation-thawing process.The current investigation is aimed at evaluating the effect of acetyl-L-carnitine on human spermatozoa and reactive species oxygen (ROS) level after freezing-thawing process.The spermatozoa were collected from 35 male patients diagnosed as having asthenospermia.The cryopreservation of human spermatozoa treated with acetyl-L-camitine at different concentrations (group B:2.5 mmol/L,group C:7.5 mmol/L,group D:15 mmol/L) was compared with control (group A:no acetyl-L-carnitine given).For the frozen-thawed spermatozoa,the viability,motility and DNA integrity were measured by comet assay,acrosome integrity by FITC-PNA staining and ROS level was determined in each group.The results showed that there were no significant differences in motility and viability between group A and group B,while the motility and viability of spermatozoa in group C and group D were significantly increased as compared with those in group A.As compared with group A,the values for DNA integrity parameters including comet rate (CR),tail DNA percentage (TD),tail length (TL) and Oliver tail moment (OTM) were significantly reduced in group C and group D.Group C and group D also displayed a higher proportion of intact acrosome than group A.No significant difference in ROS level was found between group A and group B,while with the increase in acetyl-L-camitine concentration,the ROS level in groups C and D was significantly reduced as compared with that in group A.In conclusion,acetyl-L-camitine at a concentration of 7.5 mmol/L is an effective antioxidant against cryo-damage on post-thawed human spermatozoa.

OBJECTIVETo investigate the best choice of operation opportunity and operation plan for limb fractures combined with severe craniocerebral trauma in children.

METHODSFrom January 2005 to July 2012,36 patients with limb fractures and severe craniocerebral trauma were received,including 24 males and 12 females aged from 1 to 13 years old (mean, 6.1 +/- 3.0). The time from injury to hospital was (18.0 +/- 15.0) h. Glasgow coma score were less than 8 with an average of 6.4 +/- 1.3. AIS-ISS score were 25.9 +/- 8.1. Thirteen patients were open fracture, 23 were closed fracture. Patients were divided into immediate operation group (21 patients) received fracture fixation with 24 h, the average time was (15.0 +/- 7.4) h, and delayed operation group (15 patients) received fracture fixation after 24 h, the average time was (165.4 +/- 114.6) h. All patients were treated by open reduction, and 33 cases by internal fixation, 3 cases were external fixation. Operative time, blood loss, fracture healing time and brain trauma,physical trauma, postoperative rehabilitation situation were observed and evaluated.

RESULTSAll patients were healed at stage I ,and no dead, aggravating of coma, disorders of breathing and circulation occurred during operation. Operative time,blood loss,healing time in immediate operation group was (44.5 +/- 25.3) min, (47.1 +/- 36.5) ml, (2.7 +/- 0.5) months, respectively; while in delayed operation group was (87.0 +/- 40.0) min, (112.7 +/- 67.5) ml, (3.8 +/- 1.2) months,respectively; and there were obvious differences between two groups. There was no siginificant meaning in Glasgow coma score and Fugl-Meyer motor function between immediate operation group (4.7 +/- 0.6, 97.9 +/- 2.7) and delayed operation group (4.7 +/- 0.5, 97.7 +/- 3.9) (t = 0.23, P > 0.05; t = 0.11, P > 0.05).

CONCLUSIONThe condition of limb fractures combined with severe craniocerebral trauma in children is seriously, comfortable surgical opportunity should according to particular case, and immediate operation can performed on the condition of stabled vital signs.

OBJECTIVETo explore the change of serum gamma-glutamyltransferase (GGT) and its diagnosis value in chronic hepatitis B (CHB) patients with different degrees of liver damage.

METHODSAlanine-aminotransferase (ALT), aspartate-aminotransferase (AST) and GGT were measured in 221 CHB patients. Liver biopsy was conducted simultaneously to determine the inflammation grade and fibrosis stage of the liver tissues.

RESULTSThe rate of normal GGT in pathologically diagnosed mild and severe CHB patients was 90.4% and 12.3%, respectively (P<0.01). Increased level of GGT was parallel to the degree of liver pathological change (P<0.01). In active CHB patients, GGT rose with the ALT increase with a positive linear correlation between them (r=0.464, P<0.001). In pathologically diagnosed mild CHB patients, GGT had a tendency of rapidly declining to normal levels with ALT. In moderate CHB patients, GGT fluctuated at a relatively high level, and in severe CHB patients GGT exhibited a deviation from GGT.

CONCLUSIONSGGT is conducive to improve the coincident rate between the clinical and pathological diagnosis of CHB.

OBJECTIVETo investigate the effect of parathyroid hormone related protein (PTHrP) on proliferation of human osteoblasts (MG-63) under the circumstance of tension force in vitro.

METHODSAn apparatus was designed and fabricated by which force was loaded onto the cultured cells in vitro. Reverse transcription-polymerase chain reaction (RT-PCR) was used for measuring the expression of PTHrP mRNA and c-fos mRNA. The effect of tension force and different PTHrP dose(0, 0.01, 0.1, 1 nmol/L) on the proliferation of human osteoblasts were examined using flow cytometry.

RESULTSVarious forces of the mechanical stretching exerted different influences on the intensities of the mRNA' expression. The strain of 12% induced the most remarkable mRNA' expression. The mitogenesis happened in the group with tension force (12%) combined with PTHrP was more active than that in the group with PTHrP or tension' force only. Tension force combined with PTHrP induced significantly more c-fos mRNA than that of tension force only.

CONCLUSIONThe mechanical stretching can inevitably influence the expression of PTHrP mRNA. The most active mitogenesis happened in the group with tension force combined with PTHrP. The effect may be related with the signaling pathways of c-fos.
