ABSTRACT
Objective@#To investigate the value of 1H-magnetic resonance spectroscopy (1H-MRS) in determining the content of liver triglyceride in patients with fatty liver disease (FLD), as well as its influencing factors.@*Methods@#A total of 124 patients with nonalcoholic fatty liver disease (NAFLD), chronic hepatitis B (CHB), or hepatitis B complicated by FLD who underwent liver biopsy in the Affiliated Hospital of Hangzhou Normal University were enrolled, and the clinical data, serological markers, FibroScan results, and 1H-MRS results were collected. A correlation analysis was performed with the results of liver biopsy as the gold standard, and the influence of factors including hepatitic B virus (HBV) infection and obesity on accuracy was analyzed. A one-way analysis of variance was used for comparison of means between the three groups, and the LSD or SNK test (for homogeneity of variance) or the Tamhane’s or Dunnett’s test (heterogeneity of variance) was used for comparison between any two groups. The t-test was used for comparison of continuous data between groups, and the chi-square test was used for comparison of categorical data. The MRS-PDFF receiver operating characteristic (ROC) curve was plotted, the area under the ROC curve (AUC) was calculated, the optimal cut-off points for the diagnosis of NAFLD were estimated, and sensitivity and specificity were calculated.@*Results@#The NAFLD group (42 patients) and the CHB + NAFLD group (40 patients) had a significantly higher proton density fat fraction (PDFF, the content of triglyceride in the liver) than the CHB group (42 patients) (16.84±9.76/9.39 ± 5.50 vs 3.45 ± 1.63, P < 0.001). The results were significantly correlated with the degree of steatosis confirmed by liver biopsy (P < 0.001), but it was not significantly correlated with inflammation or fibrosis grade. The correlation analysis showed that the MRS-PDFF value measured by 1H-MRS was significantly correlated with body mass index (BMI), blood lipids, alkaline phosphatase, and blood glucose, while it was not significantly correlated with age, sex, or the presence or absence of hepatitis B. The ROC curve analysis showed that the AUCs of PDFF measured by 1H-MRS were 0.93, 0.974, and 0.976, respectively, for the diagnosis of steatosis S1(≥5%), S2(≥34%), and S3(≥66%), and the corresponding optimal thresholds were 5.14%, 11.16%, and 16.7%, respectively.@*Conclusion@#1H-MRS has a high diagnostic value in quantitative evaluation of the degree of liver steatosis in patients with FLD and is not affected by the factors such as HBV infection, age, and sex, while it is correlated with BMI and lipid metabolism.
ABSTRACT
Objective@#To evaluate the short-term and long-term outcomes after laparoscopic surgery compared with traditional laparotomy in cases of stage ⅠA2-ⅡA2 cervical cancer.@*Methods@#We conducted a retrospective study on the clinical data of 1 863 patients diagnosed as FIGO stages ⅠA2-ⅡA2 cervical cancer in 6 third-grade class-A hospitals in Guangxi province between January 2007 and May 2014. One thousand and seventy-one received laparoscopy, and 792 received laparotomy. T-test, U-test and χ2 test were used to compare the short-term and long-term outcomes. The short-term outcomes included surgical related outcomes and operative complications, and the long-term outcomes included quality of life (pelvic floor functions and sexual functions), survival and recurrence. Pelvic floor function and sexual function were assessed with the International Consultation on Incontinence Quesonnaire Female Lower Urinary tract(ICIQ-FLUTS) and the Female Sexual Function Inventory (FSFI), respectively. Survival rates were estimated by Kaplan-Meier analysis. The survival curves were compared with Log-rank test. Cox regression analysis was used to evaluaterisk factors for prognosis.@*Results@#(1)The short-term outcomes : There were significant difference in operative time([(257±69) vs(238±56)min], estimated blood loss[(358±314) vs(707±431)ml], anus exhausting time[(2.5±0.9) vs (2.9±0.8)d], preserved days of catheter[(15±7) vs(18±9)d], and post-operative length of stay[(19±16) vs (30±21)d] between the laparoscopic surgery group and the opensurgery group(P<0.05). There was no significant difference in lymph nodes yielded[(21±9) vs (21±11)], left parametrial width[(2.5±0.8) vs (2.7±0.7)cm], right parametrial width [(2.6±0.3) vs (2.7±0.2)cm], vaginal cuff length[(2.4±0.7) vs (2.2±0.7)cm] between the laparoscopic surgery group and the opensurgery group(P>0.05). The intra-operative complications occurred in 8.1%(87/1 071)in the laparoscopic surgery group and in 10.7%(85/792)in the open surgery group(P>0.05). However, the complications of vascular injury in the laparoscopic surgery group[2.6%(28/1 071)]was lower than that in the open surgery group[7.7%(61/792), P<0.001]. The laparoscopic surgery exhibited lower post- operative complication rate [33.8%(362/1 071)vs 40.2%(318/792), P<0.05] and poorer wound healing rate [0.7%(7/1 071)vs 4.0%(32/792), P<0.05]. (2)The long-term outcomes(Hierarchical analysis): The overall incontinence in ICIQ-FLUTS questionnaire in nerve-sparing laparoscopic group [28.4%(67/236)] was lower than that in the open surgery group [35.9%(71/198), P=0.004] . However, There was no significant difference in degree of incontinence between the two groups(P>0.05). The overall sexual dysfunction in FSFI questionnaire after 12 months of postoperative in the nerve-sparing laparoscopic group [47.0%(111/236)]was lower than that in the open surgery group [58.6%(116/198), P=0.001], and the six different dimension scores in the laparoscopic surgery group were higher than that in the open surgery group (P<0.05). The recurrence rate was 3.5%(35/1 007)in the laparoscopicsurgery group and 4.7%(35/740)in the open surgery group(P>0.05). The 5-year OS was 94.0% for the laparoscopic surgery group and 90.2% for the open surgery group(P>0.05), and the 5-year DFS was 93.9% for the laparoscopic surgery group and 89.1% for the open surgery group(P>0.05). (3) Prognostic fators: In univariate analysis, tumor dimension, clinical stage, deep stromal invasion, LVSI, and retroperitoneal lymph node metastasis signficantly affected 5-year OS and 5-year DFS(P<0.05); In multivariate analyses, LVSI, deep stromal invasion and LN metastasis were independent prognostic factors(P<0.05).@*Conclusions@#Laparoscopy can reduceestimated blood loss, accelerate postoperative recovery and improve the quality of life after surgery compared to laparotomy, and it ensures the same oncological results as open surgery. Laparoscopic approach is a safe and effective treatment for early-stage cervical cancer.

A389T/G391A double mutation rate in HCC cases is significantly higher than that in CHB cases. In cirrhosis and HCC patients, T380C mutation rate in HBeAg(-) cases is higher than that in HBeAg(+ ) cases.
ABSTRACT
Objective@#We aimed, in our prospective study, to assess the predictive value of serum non-invasive and biochemical markers for clinical diagnosis of significant fibrosis (including early stages).@*Methods@#We measured sH2a levels in serum, comparing with routine liver function markers. We compared blindly pretreatment serum samples from a cohort of hepatitis B patients without non-alcoholic fatty liver disease(NAFLD), which had histological grades of liver fibrosis, with NAFLD individuals and CHB with NAFLD patients. Statistical analysis was by Student′s t test, and receiver-operating characteristic (ROC) curves were drawn.@*Results@#ROC curves showed that serum sH2a had greater diagnostic performance than routine liver function markers compared with histological grades of liver fibrosis(S0, S1-2, S3-4). ROC curves showed that using a sH2a cut-off point of 0.79 was with highest sensitivity as 63% and highest specificity as 80%. And sensitivity as 96.7% and specificity as 75.5% when using a sH2a cut-off point of 0.77.@*Conclusions@#sH2a has the potential to be a uniquely sensitive and specific novel marker for liver fibrosis and function.
ABSTRACT
Objective:To investigate the potential genes associated with cervical intraepithelial neoplasia (CIN) progression through mi-croarray expression profiling data analysis and bioinformatics approaches. Methods:mRNA expression microarray data related to CIN progression were screened from GEO database for the first time. They were re-analyzed by bioinformatics analysis. Results: Two mRNA expression microarray datasets were obtained from the GEO database. Pathway enrichment analysis of the common differen-tially expressed genes identified 3 signaling pathways associated with CIN progression, including Wnt, Endocytosis, and Vibrio cholerae infection. Fourteen differentially expressed genes were also identified. Biological annotation and text mining showed that 3 genes were directly related to CIN progression, and 9 other genes were associated with tumor progression and recurrence. GeneMania tool analysis demonstrated the protein interaction network formed between all the differentially expressed genes and the 24 reported genes. CCND2 and TGFBR2 formed direct interaction with many reported genes. Conclusion:Three signaling pathways and 14 differen-tially expressed genes were associated with CIN progression, as indicated by microarray data analysis results.
ABSTRACT
Objective To evaluate the clinical value of autoantibody spectrum against ovarian cancer associated antigens combine CA125 in detecting and monitoring ovarian cancer. Methods Circulating IgG, IgM autoantibodies against ovarian cancer associated antigens which included TM4SF1, C1D,TIZ, OV-142,FXR1 and OV-189 were measured by indirect ELISA in serum from 126 patients with ovarian cancer (prior treatment), 42 patients with benign ovarian masses, 142 healthy women. Cut off value of IgG, IgM autoantibodies were determined by receive operating characteristic (ROC) curve. CA125 was measured in serum by immunoradiometric assay (IRMA). We evaluated the clinical value of combining multiple autoantibodies (autoantibody spectrum ), combining autoantibody spectrum with CA125 by binary logistic regresion. The positive ratio of autoantibody spectrum in serum (prior and post treatment ) of 24 synchronization patients with ovarian cancer was analyzed to evaluate the value in monitoring state of illness.Results Our data indicated that serum contains IgG, IgM autoantibodies against ovarian cancer associated antigens. The positive ratio of IgG autoantibodies in serum from ovarian cancer patients and cancer-free patients were 34. 1% - 47. 6% and 13.0% - 19. 0%, respectively ( P ＜ 0. 05 ). The positive ratio of IgM autoantibodies in serum from ovarian cancer patients and cancer-free patients were 39. 7% - 53.2% and 12. 0% -33.2%, respectively (P ＜0. 05). The positive ratio of IgG autoantibodies against FXR1 and IgM autoantibodies against TIZ,FXR1 and OV-189 in early stage ( Ⅰ - Ⅱ ) ovarian cancer(55.3% ,63.8%,61.7% and 66. 0% ) were significantly higher than those in advanced ( Ⅲ - Ⅳ )ovarian cancer( 34. 2%,39. 2% ,26. 6% ,45.6%; all P ＜ 0. 05 ). Combining five autoantibodies ( TM4SF1 IgG, TM4SF1 IgM, C1D IgG, FXR1 IgG and TIZ IgM ) showed significantly improved sensitivity (75.4%, P ＜ 0. 05 ), lower specificity (78. 3% ,P ＜ 0. 05 ) and similar accuracy (77. 1%, P ＞ 0. 05 ) in detecting ovarian cancer compared to those of CA125 (61.1% ,88.0% ,77. 1% ). But the autoantibody spectrum showed significantly improved sensitivity in classifying early stage (76. 6% ), compared to those of CA125 (51.1% ,P ＜ 0. 05 ).Combining autoantibody spectrum with CA125 showed significantly improved sensitivity ( 85.7% ), specificity (90. 8% )and accuracy (88.7%) in detecting ovarian cancer compared to those of autoantibody spectrum alone ( all P ＜ 0. 05 ), while CA125 ( 61.1%, P ＜ 0. 05; 88. 0%, P ＞ 0. 05; 77. 1%, P ＜ 0. 05 ). The positive ratio of combine the autoantibody spectrum with CA125 was significantly lower in 24 post-treatment serum (42%) compared to the pairing prior treatment serum ( 88%, P ＜ 0. 05 ). Conclusion Combining the autoantibody spectrum against ovarian cancer associated antigens with CA125 can improve sensitivity,specificity and accuracy in detecting early ovarian cancer and may be used to monitoring state of illness.

ABSTRACT
<p><b>OBJECTIVE</b>To study the optimal position and method for ovarian transposition and its benefits and indications.</p><p><b>METHODS</b>We performed ovarian transposition in 34 patients from August 1989 to December 2000. Twelve patients were diagnosed with stage Ib to IIa cervical cancer, 4 had stage Ia endometrial carcinoma, 12 had stage III to IV endometriosis, 4 had myoma of uterus, 1 had dysfunctional uterine bleeding, and 1 had an ovarian granulosa cell tumor. Surgery went as follows: the ovary was dissociated by clamp, the skin was incised and a tunnel was made, then the ovary was translocated to the subcutaneous site. In the cases of benign lesions, the ovarian vessel pedicel went in through the abdominal cavity, but in malignant tumors, it went out through the peritoneum.</p><p><b>RESULTS</b>In both cases (benign lesions or malignant tumors), the short-term and long-term endocrine function of the translocated ovary remained normal. Furthermore, patients could supervise their translocated ovary themselves.</p><p><b>CONCLUSIONS</b>Subcutaneous ovary transposition might prevent not only implantation of gastrointestinal cancer but also the extension of pelvic carcinoma to the ovary. Because of the shallow transposition and the incision scar, it is easy for patients to supervise themselves. Moreover, the site of the ovary is easy to locate for ultrasound examinations. Thus, it can obtain the goal of early prevention for cancer. Subcutaneous ovarian transposition with skin incision is the optimal selection and suitable for all patients with various gynecologic diseases in which ovary removal is not necessary.</p>
