OBJECTIVETo compare the differences in the efficacy on distant version of naked eye in the patients of juvenile myopia between rotating manipulation and lifting-thrusting manipulation of acupuncture.

METHODSOne hundred and twenty cases (240 eyes) were randomized into a rotating manipulation group and a lifting-thrusting manipulation group, 60 cases (120 eyes) in each group. Additionally, a corrective lenses group, 60 cases (120 eyes), was set up as the control. In both manipulation groups, Cuanzhu (BL 2),Yuyao (EX-HN 4), Sizhukong (TE 23), Taiyang (EX-HN 5), Fengchi (GB 20), Zusanli (ST 36), Guangming (GB 37) and Sanyinjiao (SP 6) were punctured, but stimulated with rotating manipulation and lifting-thrusting manipulation respectively three times per week, 10 times as a treatment session and totally one session was required. In the corrective lenses group, the glasses were applied at daytime. The clinical efficacy and the changes in distant vision of naked eye before and after treatment were compared among the three groups.

RESULTSThe total effective rate was 87.5% (105/120) in the rotating manipulation group, which was better than 69.2% (83/120) in the lifting-thrusting manipulation group (P < 0.05). The distant vision of naked eye was improved apparently in the rotating manipulation group and the lifting-thrusting manipulation group after treatment (both P < 0.05). But it was not improved in the corrective lenses group (P > 0.05). The distant vision of naked eye was improved more apparently after treatment in the rotating manipulation group as compared with that in the lifting-thrusting manipulation group (0.75 +/- 0.23 vs 0.68 +/- 0.24, P < 0.05). For 96 cases (192 eyes) with acupuncture treatment, in 3-month follow-up, 87.0% (167/192) of the cases maintained the stable vision as the original level and 13.0% (25/192) of them were reduced in the vision In the acupuncture groups, it was found that the improvement of distant vision of naked eye was more obvious after treatment with younger age, better basic vision and shorter duration of sickness (all P < 0.05).

CONCLUSIONAcupuncture achieves the positive and sustainable clinical effect on juvenile myopia, and the results of rotating manipulation are superior to that of lifting-thrusting manipulation. Age, basic vision and duration of sickness impact the clinical efficacy.

OBJECTIVETo study the immunophenotypic and genetic features of diffuse large B-cell lymphomas (DLBCLs), and their relationship to prognosis.

METHODSSeventy-three cases of DLBCLs with follow-up data were studied by using immunohistochemistry for CD3, CD10, CD20, bcl-6 and MUM-1. The DLBCLs were classified into germinal center B cell-like (GCB) and non-germinal center B cell-like (non-GCB) subtypes according to Hans' algorithm. Fluorescence in-situ hybridization (FISH) for bcl-6 gene expression (located on chromosome 3q27) was performed on paraffin-embedded tissues of 54 cases.

RESULTSIn the 73 cases studied, 16 cases (21.9%) belonged to GCB subtype and 57 cases (78.1%) belonged to non-GCB subtype. Breakage of 3q27 was detected in 11 of the 54 cases (20.4%) and proliferation was detected in 14 cases (25.9%). The five-year overall survival rate of GCB subtype was significantly higher than that of non-GCB subtype (78% versus 40%, P = 0.011). The bcl-6-positive cases had a better clinical outcome than that of the bcl-6-negative cases (P = 0.041). Breakage of 3q27 predicted a worse overall survival.

CONCLUSIONSThe current study shows that the prognosis of GCB subtype of DLBCLs is better than that of non-GCB subtype. The expression of bcl-6 protein predicts a better clinical outcome, while the breakage of 3q27 predicts a worse overall survival.

OBJECTIVETo investigate the relationship between polymorphisms of genes (CYP17, CYP19 and SULT1A1) involved in estrogen metabolism and susceptibility to breast cancer in Chinese women.

METHODSA case-control study was performed. PCR-base restriction fragment length polymorphism (PCR-RFLP) and short tandem repeat polymorphism (STRP) assays were used to detect the polymorphism distribution of CYP17, CYP19 and SULT1A1 in 213 breast cancer cases and 430 matched controls. Logistic regression analyses were used to determine the OR, multivariate adjusted OR and 95% CI of each and all three genes and estrogen exposure factors on the risk of breast cancer. Relationship between polymorphisms and clinic-pathological features was also assessed.

RESULTSThe frequency of A2 allele of CYP17 was 49.8% in cases and 49.1% in controls (P > 0.05). The frequency His allele of SULT1A1 in cases (13.6%) was significant higher than that of controls (9.5%) (P = 0.03). There was also significant difference in the frequencies of (TTTA)10 allele CYP19 which was 12.4% in cases and 8.2% in controls (P = 0.02). Multigenic model indicated that there was an increased risk of breast cancer with more numbers of high-risk genotypes in a dose-response effect (trend P = 0.05). Data from multivariate analysis showed that the allele of SULT1A1 His and CYP19 (TTTA)10 was positively associated with the risk of breast cancer. Other well-established risk factors as higher estrogen exposure including total years of menstrual, early menarche etc, and women with a higher BMI and WHR were all served as independent risks.

CONCLUSIONThis study indicated that the polymorphisms of estrogen-metabolizing genes were related to breast cancer.

OBJECTIVETo investigate the molecular genetic causes and their characteristics of deafness in Ningxia province, we established screening of three common hereditary deafness genes in 336 deaf and hard-of-hearing patients in this district.

METHODSPeripheral blood samples were obtained from a total of 336 patients with non-syndromic sensorineural hearing loss in parts of special education schools in Ningxia province to extract genomic DNA. The mitochondrial DNA 12S rRNA m.1555A > G mutation was screened by PCR Alw26I digestion and sequence analysis PCR and direct sequencing were used to analyze the coding region of GJB2 and exons 8 and 19 of SLC26A4. Statistical analysis was performed by using SPSS 11.0 software. Frequencies of different GJB2 or SLC26A4 mutations were compared between Han and Hui people.

RESULTSAmong these 336 patients, seven cases (2.08%, 7/336) were found to carry mtDNA 12S rRNA m.1555A > G homozygous mutation, 45 cases (13.39%) were caused by GJB2 mutations and 28 cases (8.33%) had two mutated alleles (homozygote and compound heterozygote) of SLC26A4. In detail, 16.67% (56/336) patients carried GJB2 mutations including 11 single mutant carriers. The allele frequency of c.235delC and c.299_300delAT were 9.52% (64/672) and 2.68% (18/672), respectively, making up 81.19% (82/101) of all pathogenic mutated alleles for GJB2. The single mutant allele carriers of SLC26A4 is 32, and two types (c.919-2A > G and c.2168A > G) accounted for 95.29% (24/27) mutations, totally. We also found that statistically significant differences in c.919-2A > G and c.2168A > G frequencies between Han and Hui people (c.919-2A > G, χ(2) = 8.229, P = 0.004; c.2168A > G, χ(2) = 5.277, P = 0.022). However, there was no statistically significant difference in GJB2 mutation between Han and Hui people.

CONCLUSIONSGJB2 mutation was a primary cause for non-syndromic sensorineural hearing loss in Ningxia province, and c.235delC was the most common mutant forms of GJB2. c.919-2A > G and c.2168A > G were common mutant forms of SLC26A4, their frequencies were also statistically significant differences between Han and Hui people.

OBJECTIVETo study the frequency of certain specific genetic aberrations, including t (11; 18)/API2-MALT1, t (1; 14)/IgH-bcl-10 and t (14; 18)/IgH-MALT1, in mucosa-associated lymphoid tissue (MALT) lymphoma of different sites.

METHODSOne hundred and ninety-six cases of MALT lymphoma from Cancer Hospital of Fudan University were enrolled into the study. The samples consisted of MALT lymphomas from stomach (53 cases, including 44 cases of low-grade MALT lymphoma and 9 cases of MALT lymphoma with diffuse large B-cell lymphoma component), ocular adnexa (50 cases), salivary gland (20 cases), lung (20 cases), intestine (17 cases), skin (17 cases), liver (8 cases), thyroid (5 cases) and other sites (2 cases from tongue, 1 case from pancreas, 1 case from larynx, 1 case from vocal cords and 1 case from kidney). Fluorescence in-situ hybridization for API2-MALT1 fusion gene, bcl-10, MALT1 and IgH genes was performed on paraffin sections.

RESULTSAmong the 196 cases of MALT lymphoma, 25 cases (12.8%) possessed API2-MALT1 fusion gene. The positive rates in various sites were significantly different (P = 0.002), as follows: 45.0% (9/20) in lung, 22.7% (10/44) in stomach (without large cell component), 15.0% (3/20) in salivary gland, 2 of 17 cases in intestine and 2.0% (1/50) in ocular adnexa. The fusion gene was not detected in the 9 cases of gastric MALT lymphoma with large cell transformation. It was also negative in the MALT lymphomas from skin, thyroid and other sites. One of the pulmonary MALT lymphoma cases showed simultaneous aberrations of IgH and MALT1 genes, such as t (14; 18)/IgH-MALT1. Two of the gastric MALT lymphoma cases without large cell transformation and one of the pulmonary MALT lymphoma cases showed aberrations in both IgH and bcl-10 genes, such as t (1; 14)/IgH-bcl-10. Six cases of MALT lymphoma, including 2 cases from salivary gland, 2 cases from liver, 1 case from thyroid and 1 case from stomach (large cell transformation), showed trisomy 18. On the other hand, 3 cases, including 2 cases from stomach and 1 case from intestine, showed MALT1 gene amplification.

CONCLUSIONSIn general, specific genetic aberrations have a relatively low frequency of occurrence in MALT lymphomas. The positive rates however show a remarkable difference in tumors of different anatomic sites. This phenomenon may suggest that MALT lymphomas in different sites, though sharing similar morphologic features, may have a divergent tumorgenesis.

OBJECTIVETo evaluate the diagnostic role of nuclear expression of bcl-10 protein in extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT) type.

METHODSOne hundred and forty cases of MALT lymphoma were collected from Cancer Hospital of Fudan University (including 38 cases from stomach, 35 cases from ocular adnexa, 16 cases from intestine, 15 cases from skin, 15 cases from salivary gland, 14 cases from lung, 3 cases from thyroid and 4 cases from other sites). Ten cases of reactive follicular hyperplasia of tonsil, 5 cases of reactive lymphoid hyperplasia of orbit and 143 cases of non-Hodgkin's lymphoma other than MALT lymphoma (including 20 cases of NK/T cell lymphoma, 20 cases of follicular lymphomas, 20 cases of anaplastic large cell lymphomas, 20 cases of nodal diffuse large cell B-cell lymphoma (DLBCL), 10 cases of gastric diffuse large B-cell lymphoma, 13 cases of nodal marginal zone B-cell lymphoma, 12 cases of mantle cell lymphoma, 11 cases of splenic marginal zone B-cell lymphoma, 6 cases of angioimmunoblastic T-cell lymphoma, 6 cases of peripheral T-cell lymphoma, not otherwise specified, 3 cases of small lymphocytic lymphoma, 1 case of lymphoplasmacytic lymphoma and 1 case of plasmacytoma were used as controls. Immunohistochemical study for bcl-10, as well as dual staining with CD20, was performed by EnVision method in paraffin sections.

RESULTSIn reactive follicular hyperplasia of tonsil, bcl-10 was moderately or strongly expressed in the cytoplasm of germinal center B cells, while the mantle cells were negative and the marginal zone cells and paracortical T cells showed weak staining. In the 5 cases of reactive lymphoid hyperplasia of orbit, 2 were bcl-10-negative and the remaining 3 expressed bcl-10 in the cytoplasm of germinal center B cells. As for non-MALT lymphomas, 3 gastric DLBCL showed nuclear expression. The remaining cases showed variable cytoplasmic staining. In some cases of lymphoma, bcl-10 was expressed in tumor cells but not in reactive lymphoid cells. On the other hand, 92.1% (129/140) of MALT lymphoma were bcl-10 positive. Among those cases, 54.3% (76/140) showed cytoplasmic positivity and 37.9% (53/140) showed nuclear positivity. The nuclear positivity rate of bcl-10 in different anatomic sites was different. The staining was most intense in MALT lymphoma of ocular adnexa. Dual staining with CD20 showed that the bcl-10-positive cells were also CD20-positive, though the number of bcl-10-positive cells were less than that of CD20-positive cells.

CONCLUSIONSBcl-10 expression in lymphoid hyperplasia is a universal phenomenon. Cytoplasmic expression of bcl-10 is seen in many different kinds of non-Hodgkin's lymphoma and reactive lymphoid conditions. In some cases of lymphoma, bcl-10 is expressed in tumor cells but not in reactive lymphoid cells, suggesting a possible role of abnormal bcl-10 expression in tumorgenesis. Nuclear expression of bcl-10 is seen mainly in MALT lymphoma, especially when occurring in ocular adnexa and lung. This is in contrast to loss of bcl-10 expression in residual germinal center cells.

BACKGROUND AND OBJECTIVEMonitoring the therapeutic effects of radiotherapy for nasopharyngeal carcinoma (NPC) is critical to providing individualized treatment. This in-vivo study was initially designed to evaluate the therapeutic effect of radiotherapy using 18F-fluorodeoxyglucose positron emission tomography with computed tomography (18F-FDG PET-CT) imaging.

METHODS18F-FDG PET-CT imaging was performed on all of the 10 nude mice bearing NPC xenografts before radiotherapy, and early-phase and delayed-phase PET-CT images were performed on 7 of the 10 mice. All mice were randomly divided into either a control group or a radiotherapy group. The 5 mice in the control group were immediately killed after the imaging and pathology were performed. After receiving radiotherapy of 12 Gy, 5 animals in the radiotherapy group were given 18F-FDG PET-CT imaging on days 2, 4, and 6, and then were killed for pathologic evaluation. Regions of interest (ROI) technology was used to measure the tumor target/non-target (T/NT) ratio and the volume of the tumors.

RESULTSThe average T/NT ratios of early- and delayed-phase imaging were 1.806 +/- 0.532 and 1.777 +/- 0.597, respectively, with no significance (P > 0.05). For the radiotherapy group, the average T/NT ratios for 18F-FDG PET-CT before radiotherapy, and on days 2, 4, and 6 after radiotherapy, were 1.735 +/- 0.466, 1.818 +/- 0.396, 1.096 +/- 0.101, and 0.604 +/- 0.108, respectively, The tumor volumes were (1.48 +/- 0.27) cm3, (1.57 +/- 0.31) cm3, (1.59 +/- 0.31) cm3 and (1.60 +/- 0.29) cm3, respectively. The average T/NT ratios of day 6 after radiotherapy and the other time points were significant (P < 0.05). The average death ratio of the tumor cells was (93.00 +/- 7.42)% after 6 days of post-radiotherapy.

CONCLUSIONS18F-FDG PET-CT imaging can be used for the early assessment of radiotherapeutic effect of NPC in vivo. Day 6 after radiotherapy may be an appropriate time point for the imaging. However, the T/NT ratio measurement of delayed-phase imaging might make no sense for the diagnosis of NPC.

BACKGROUNDPulmonary thromboembolism (PTE) has become a common disease that severely endangers people's health. This study analysed the changes in proportion and mortality of PTE in hospitalized patients to provide data for prevention and management of the disease.

METHODSThe data of 763 hospitalized patients with PTE from 1974 to 2005 in Fuwai Hospital were analysed.

RESULTSDuring the 1970s, 0.27% of patients in a cardiovascular hospital had PTE (< 5 cases per year); while so far this century the proportion is 0.94% (48 to 113 per year). The mortality of hospitalized PTE patients fell from 20.00% in the 1970s to 4.10% this century. Prior to 1990, the mortality of hospitalized PTE patients was 12.50%, and in the years after 1990 only 3.40%. The difference was statistically significant (P < 0.005). People with this disease were mostly between the ages of 30 and 69 years. Men were most susceptible between the ages of 30 and 69 years, while women between the ages of 40 and 69 years. Men contracted PTE 10 years earlier than women. The mortality of male PTE patients was 4.70%, not significantly different from female patients, 5.06% (0.50 < P < 0.75). There were not any significant differences between the mortality of patients in the different age groups overall (< or = 39, 40 - 49, 50 - 59, and > or = 60 years, P > 0.1). More people contracted the disease in winter than in other seasons (P < 0.05). There was no obvious difference between the mortality in different seasons overall (0.75 < P < 0.90).

CONCLUSIONPTE is an increasingly significant disease and deserves adequate attention.

There are growing evidences that pinocembrin has better neuroprotective effect. In the present study, the effect of pinocembrin on mitochondrial respiratory function was evaluated in global brain ischemia/ reperfusion (4-vessel occlusion, 4-VO) rats. The results showed that pinocembrin improved the respiratory activity of 4-VO brain mitochondria, through increasing ADP/O, state 3 respiration state (V3), respiration control rate index (RCI) and oxidative phosphorylation rate (OPR). And then, the effect of pinocembrin on brain mitochondria was verified in vitro. The results showed that pinocembrin increased ADP/O, state 3 respiration state, respiration control rate index, oxidative phosphorylation rate in NADH/FADH2 dependent respiratory chain and decreased state 4 respiration state (V4) in NADH dependent respiratory chain. Pinocembrin improved ATP content in brain mitochondria in vitro and in SH-SY5Y cells.
