OBJECTIVETo evaluate the clinical value of perioperative adjuvant chemotherapy in prevention of tumor recurrence and improvement of patient survival after liver transplantation for advanced hepatocellular carcinoma (HCC).
METHODSTwenty patients with advanced HCC (pTNM stages III and IV a) receiving liver transplantation with preoperative transcatheter arterial chemoembolization (TACE) and postoperative adjuvant chemotherapy (ADM+5-Fu+CDDP) were retrospectively reviewed in comparison with 16 patients receiving liver transplantation only for tumor recurrence, cumulative and tumor-free survivals. The feasibility and side-effects of the treatments were also studied.
RESULTSThe recurrence rate was lower in the perioperative treatment group than in non-treatment group (12/20, 60.0% vs 11/16, 87.5%, P<0.05). The 1- and 2-year overall survival rates were 70.8% and 47.1% for the chemotherapy group and 43.8% and 20.5% for the non-chemotherapy group respectively, showing significant differences between them (P<0.05). The 1- and 2-year tumor-free survival rates were 60.6%, 40.5% and 33.6%, 15.6% in the two groups, respectively, with also significant differences (P<0.05).
CONCLUSIONSPerioperative adjuvant treatment may significantly decrease the likeliness of tumor recurrence and prolong the survival of patients with advanced HCC after liver transplantation. Chemotherapy with ADM+5-Fu+CDDP can be effective and safe with only mild side-effects.

OBJECTIVETo evaluate the performance of computer-assisted imaging system in the detection of cervical squamous intraepithelial lesion and quality-assurance.
METHODSManual PAP screening (n = 140 580) and image-assisted screening (n = 32 885) were compared for the detection rates of squamous cell abnormalities, the atypical squamous cells (ASC) to squamous intraepithelial lesion (SIL) ratio, the positive rates of high risk human papillomavirus (HR-HPV) test in the case of atypical squamous cells of undetermined significance (ASC-US), and the correlation between cytopathology and histopathology.
RESULTSCompared with manual screening, computer-assisted imaging system showed increased overall positive detection by 0.32%, decreased detection of ASC by 0.21%, increased detection of low-grade squamous intraepithelial lesion (LSIL) by 0.22%, increased detection of high-grade squamous intraepithelial lesion or worse (HSIL) by 0.31%, and decreased ASC to SIL ratio from 2.59 to 1.60. Computer-assisted imaging system did not change the HR-HPV positive rate of the patients who were ASC-US, or the coincidence rate between cytopathology and histopathology. Moreover, the productivity of the laboratory operation increased 58.33%.
CONCLUSIONComputer-assisted imaging system significantly increases the overall positive detection rate of cervical SIL, improves accuracy and work efficiency of screening, decreases the ASC/SIL rate, and strengths the quality-assurance of laboratory testing.

OBJECTIVETo study the protective effect of Sanhuangyinchi Fang drug serum (SF) against hydrogen peroxide-mediated DNA oxidative damage in LO2 cells.
METHODSThe LO2 cells were randomly divided into the control group, H(2)O(2) group, SF groups (5%, 10%, and 15%) and vitE group. The morphological features of the treated LO2 cells were observed under inverted microscope. The viability of the treated cells was assessed with CCK-8 method, and the activity of SOD, CAT and GSH-PX were detected biochemically. Reactive oxygen species (ROS) levels, the content of 8-OHdG, and DNA damage of the cells were evaluated by flow cytometry, ELISA, and Comet assay, respectively.
RESULTSCompared with H(2)O(2) group, the cells in SF groups (10% and 15%) and vitE group showed higher cell survival rate (P<0.05) and higher SOD, CAT, GSH-PX (P<0.05) and ROS scavenging activities (P<0.01) with markedly decreases the content of 8-OHdG (P<0.01) and reduced tailing ratio, tail length, tail moment and Olive tail moment (P<0.05).
CONCLUSIONSF drug serum, especially at the concentration of 15%, can protect LO2 cells from H(2)O(2)-mediated DNA oxidative damage.

ObjectiveTo investigate the effects of acupuncture combined with Du-Moxibustion (ADM) on peripheral blood cell count and levels of immune factors in patients with occupational chronic benzene poisoning. Methods A total of 70 patients with occupational chronic benzene poisoning (leukopenia and neutropenia) were selected as the research subjects by judgement sampling method. They were randomly divided into a control group and an ADM group using a random number table method, with 35 cases in each group. Patients in the control group were treated with conventional Western medicine such as leukocyte boosting and symptomatic treatment. While patients in the ADM group were treated with ADM treatment in addition to treatments of the control group, once per week for five consecutive weeks. Peripheral blood samples of patients were collected before and after treatment from both groups, to detect cell counts and serum levels of immune factors. Results The white blood cell count, red blood cell count, absolute lymphocyte count, absolute neutrophil count, platelet count, and levels of hemoglobin, immunoglobulins (Ig) A, IgM, IgG, complement C3 and complement C4 of patients in both groups improved after treatment compared with those before treatment (all P<0.05). The white blood cell count, levels of IgA, IgM, IgG, complement C3 and complement C4 of patients in the ADM group were higher than those in the control group after treatment (all P<0.05). Conclusion ADM treatment can increase peripheral blood white blood cells and serum levels of immune factor in patients with occupational chronic benzene poisoning (leukopenia, neutropenia), which helps improve patient recovery and can be promoted clinically.

To understand the characteristics of T cell receptors recognizing antiphospholipid syndrome associated antigen, the characteristics of T cells were analyzed using T cell receptor beta variable region (TCRbetaV) gene spectrotyping in a case of antiphospholipid syndrome (APS). The results indicated that in the case of APS there were 2 dominant T cell clones. The TCRbetaVs sequences of the 2 T cell clones showed the TCRbetaVs belonged to 8 and 23 gene families respectively. The peptides of third complementarity-determining regions (CDR3) in the TCRbetaVs were CASSLLVAGGPRAYNEQFFGPG and CASSLAGFGQPQHFGDG. Comparing the motifs in CDR3 with another autoimmune disease, the motif YNEQFFGPG in TCRbetaV8 and motif QHFGDG in TCRbetaV23 were identical with that of idiopathic thrombocytopenic purpura and systemic lupus erythematosus reported before. In conclusion, some T cell clones proliferating in these autoimmune diseases may recognize the same antigens.

Up to December of 2011, the domestic and overseas literatures of acupuncture for smoking cessation are searched and collected through Pubmed, CNKI, Wanfang and Chongqing VIP databases, which are analyzed from treatment method, action mechanism, influencing factors of efficacy and efficacy evaluation research and so on. The result shows that (1) acupuncture has positive effect on smoking cessation, and large clinical trials has been carried out. However, most of them are needling methods and the short-term effect observation, which lack of long-term efficacy research of withdrawal symptoms, especially continuous withdrawal symptoms and index of life quality. (2) Because of unified clinical treatment, manipulation standard and curative effect criteria, it is difficult to make comparison among them. (3) The study of mechanism on acupuncture for smoking cessation is not of in-depth. In future, clinical research project of acupuncture on smoking cessation should be optimized and regulated, including the unified treatment, manipulation standard and curative effect criteria, also long-term researches with large-scale samples should be launched to confirm effect ofacupuncture for smoking cessation to further discuss its action mechanism.

OBJECTIVETo evaluate the sensitivity and usefulness of 99mTc-sestamibi scintigraphy (SS) and neck ultrasonography (US) as preoperative localization procedures in patients with primary hyperparathyroidism (pHPT).
METHODS160 patients with proved pHPT in Peking Union Medical College Hospital from June 1983 to June 2002 were studied. There were 107 women(66.9%) and 53 men (33.1%), with a mean age of 38.9 years (10-73 years). 100 patients were underwent SS and 148 patients were underwent US prior to surgery, and the results were compared with operative and histological findings.
RESULTSThe sensitivity of SS and US in localization of the enlarged parathyroid glands was 94.0% and 85.1% respectively, and the positive predictive value of SS and US was 100% and 89.1% respectively, the overall sensitivity was 98.9% by combination of SS and US. In solitary parathyroid adenomas group (n = 145), the sensitivity of SS and US was 93.3% and 84.7% respectively; There was no significant difference (P = 0.428) in sensitivity of SS between the parathyroid glands correctly identified and undetected in classical neck location as compared with ectopic parathyroid glands, whereas significantly (P = 0.026) influenced by the US sensitivity.
CONCLUSIONSDifferent sensitivity exit between SS and VS in preoperative localization in patients with pHPT undergoing parathyroidectomy. The combined use of SS and US could increase the sensitivity of localization technique. Ectopic parathyroid had no influence on the sensitivity of 99mTc-MIBI scanning, but decreased the sensitivity of ultrasonography. The size of parathyroid tumors had effects on the sensitivity of ultrasonography. Otherwise, various conditions causing SS false negative were observed. Some interfere factors should be excluded when SS negative results were encountered in clinical practice.

OBJECTIVE To analyze a neonate with multiple malformations and to correlate its genotype with phenotype. METHODS The karotypes of the child and her parents were subjected to G-banding chromosome analysis, and array comparative genomic hybridization (array-CGH) was used for fine mapping of the aberrant region. RESULTS The karyotype of the child was ascertained as 46,XX,del(18)(p11.2). Array CGH has identified a 9.8 Mb deletion at 18p11.32-p11.22. The patient has presented features such as holoprosencephaly, choanal atresia, heart defect, and craniofacial dysmorphisms. CONCLUSION The de novo 18p deletion probably underlies the main clinical manifestations of the child.
