OBJECTIVETo evaluate the efficacy and safety of deferasirox in heavily iron-overloaded patients with beta-thalassemia major.
METHODSA single arm, open-label clinical trial was conducted to evaluate the efficacy and safety of deferasirox in the treatment for 23 patients with beta-thalassemia major and heavily iron-overloaded in 3 years follow-up.
RESULTSThe 23 patients never received regular chelation before enrolling this trial [the mean baseline of serum ferritin was (5433.96 ± 2873.90) µg/L]. In this trial, a deferasirox dose of 20 mg×kg(-1)×d(-1) could stabilize serum ferritin levels, while of ≥ 30 mg×kg(-1)×d(-1) reduced the levels and achieved negative iron balance. There were no serious adverse events related to the drug. Most common adverse events were mild increases of liver enzyme and serum creatinine levels. Overall, 23 patients could tolerate the drug on schedule and all completed the trial.
CONCLUSIONAs a new oral iron chelator, deferasirox has a significant efficacy for the treatment of iron overload. The effectiveness is dependent on the courses of treatment and the dose of deferasirox. The single-dose used is safe and tolerated, so deferasirox can remarkably improve life quality of patients.

Objective To understand female outpatients' recognition towards cervical cancer screening and their related attitudes and behaviors so as to provide theoretical basis for nursing intervention aimed at improving the rate of cervical cancer screening.Methods 1116 female outpatients at Sun Yat-sen University Cancer Center were investigated with random sampling method by using a questionnaire of cervical cancer screening knowledge and related attitudes and behaviors.Results The cognitive aspects of cervical cancer screening rates were different among different ages,cultures,incorne women,differences were statistically significant(χ2=42.377,138.7,32.519,P<0.01).This study demonstrated patients with high-level education and good economic situation knew more about cervical cancer screening. Most of them (76.3%) approved the view of "Early detection of cervical cancer could improve survival". But only 47.5% patients approved "Screening could detect the cervical cancer early", and 45.3% patients were willing to accept the cervical cancer screening. 43.8% patients had received the cervical cancer screening, and only 4.9% patients received the screening annually.The cervical cancer screening rates were different ages,cultures,income women,differences were statistically significant(χ2=16.155,9.052,28.801,P<0.01).Conclusions Outpatients' knowledge about the cervical cancer screening is insufficient, patients with low-level education and poor economic situation know less about cervical cancer screening and the rate of their accepted cervical cancer screening is low. Nursing staff should help them establish a positive attitude, improve their cognition towards cervical cancer screening, and take different methods to provide health education of cervical cancer screening based on their actual conditions so as to improve the low rate of cervical cancer screening.

OBJECTIVETo investigate the effects of Trichophyton rubrum exposure on the expressions of toll-like receptor-2 (TLR-2), TLR-4 and dendritic cell associated C-type lectin-1 (Dectin-1) and cytokine secretions in human keratinocytes cell line HaCaT.
METHODSThe mRNA of TLR-2,4, and dectin-1 in the HaCaT co-cultured with the conidia of Trichophyton rubrum conidia for 24 h was measured with real-time PCR. The mean fluorescence intensity and the percentage of cells positive for TLR-2, 4, and dectin-1 was detected during the co-culture using flow cytometry. The cytokine secretion profiles in the cell culture supernatant was analyzed using a cytokine antibody array.
RESULTSThe TLR-2,4, and dectin-1 mRNA expressions, mean fluorescence intensity and percentage of positive cells for TLR-2,4, and dectin-1 all increased in HaCaT cells in response to Trichophyton rubrum conidia exposure. The results of cytokine antibody array demonstrated obviously increased secretions of IL-8, I-309, IFN-γ, IL-6, and IL-13 in the culture supernatant of HaCaT cells in response to Trichophyton rubrum exposure.
CONCLUSIONThe immune responses and immunological recognition of human keratinocytes to Trichophyton rubrum conidia are partially mediated by up-regulating the expressions of TLR-2, TLR-4 and dectin-1 and secretions of multiple cytokines.

OBJECTIVETo investigate the value of narrow band imaging (NBI) endoscopy in the detection of unknown primary tumor site with cervical lymph node metastases of squamous cell carcinoma.
METHODSFifty-three patients with cervical lymph node metastases of squamous cell carcinoma treated in our department between June 2009 and December 2011 were enrolled in this study. Their primary tumor site was not detected by routine computed tomography, magnetic resonance imaging and laryngoscopy. The nasopharyngolarynx was examined by NBI endoscopy to explore the primary tumor site.
RESULTSA total of 53 cases with cervical lymph node metastasis of squamous cell carcinoma from an unknown primary were examined under NBI endoscopy. The primary tumor site was confirmed by NBI examination in 47.2% (25/53) of patients, significantly better than routine radiology and endoscopy (0, P < 0.001). These primary tumors were small and superficial, with characteristic mucosal vascular morphologies. The superficial nasopharyngeal carcinomas under NBI examination showed the superficial thin branch-like or torturous line microvessels. The notable characteristics of the squamous cell carcinoma of oropharynx, hypopharynx and larynx was the well demarcated brownish area and scattered brown dots.
CONCLUSIONThe NBI endoscopy can provide better visualization of the morphology of superficial mucosal vasculature and improve the ability to detect possible primary cancer in patients with primary unknown cervical lymph node metastasis.

BACKGROUNDDespite recent advances in recognition and treatment of primary palmar hyperhidrosis (PPH), the epidemiological survey has hardly been conducted. The aim of this study was to investigate the prevalence and epidemiological characteristics of primary PPH among adolescents in three cities of southeast China.
METHODSStratified-cluster sampling was carried out and cross-sectional epidemiological survey by questionnaire was applied among 33 000 college and high school students.
RESULTSThe prevalence rate of PPH was 4.36% affecting both sexes equally. Prevalence rate of severe PPH was 0.27%. The average age of onset was 12.27 +/- 2.12 years. The peak age of onset was 6 - 16 years, accounting for 97.2% of PPH population. Positive family history was found in 17.9% PPH cases. Besides palms, axillae and soles can be also affected.
CONCLUSIONSPPH affects a larger group of individual than previously reported. More measures should be taken to enhance the recognition, diagnosis, and treatment of PPH.

Objective To investigate the method displaying the hypopharynx and esophageal entrance under laryngoscopy to determine the invasion range of hypopharyngeal cancer.Methods A total of 113 patients with hypopharyngeal cancer was enrolled in this study and they previously underwent conventional laryngoscopic and radiologic examinations.The esophageal entrance was exposed by injecting gas through the biopsy channel of laryngoscope.The invasion of esophageal entrance in hypopharyngealcancers was evaluated by this method and compared with that evaluated with radiology. Results Conventional laryngoscopy was unable to evaluate appreciably esophageal entrance involvement in the 113 patients with hypopharyngeal cancer.After injecting gas through the laryngoscopic biopsy channel,the esophageal entrance was clearly displayed in 96.5% (109/113 ) patients,showing the presence (33 cases)and absence (76 cases) of esophageal entrance invasion.Imaging examinations only showed the invasion of the esophageal entrance in 25 patients of these patients,but did not in other 8 patients.Laryngoscopy with injecting gas through the biopsy channel was superior to radiological imaging examinations in determining the invasion of the esophageal entrance ( x2 =9.103,P =0.003 ).Conclusion Laryngoscopy with injecting gas through the biopsy channel is a useful method for determining the presence or absence of esophageal entrance invasion in hypopharyngeal cancer prior to surgery.

OBJECTIVETo compare the differences in the effect of laparoscopic cholecystectomy (LC) with different anesthetic methods on T-lymphocyte immune function and postoperative analgesia as well as validate the specificity of meridian points.
METHODSNinety cases of LC were randomized into three groups, named group A (compound general anesthesia group with meridian points involved), group B (compound general anesthesia group with placebo points involved) and group C (general anesthesia group). In group A, electroacupuncture was applied at first for 15 to 30 min to bilateral Hegu (LI 4), Neiguan (PC 6), Zusanli (ST 36), Yanglingquan (GB 34) and Quchi (LI 11). Afterwards, the general anesthesia was conducted and electric stimulation lasted till the end of operation. In group B, the points adopted were the midpoints between the meridians in which the acupoints were selected in group A and the adjacent meridians on the lateral side, at the level of selected meridian points correspondingly. The method and time of electroacupuncture were same as those in group A. In group C, the general anesthesia was adopted simply. The changes of T-lymphocyte subgroup were detected before anesthesia, in 2 h, 1 day and 3 days after operation separately; and the dose of narcotic in operation as well as the dose of analgesia pumper in 4 h, 6 h, 8 h, 24 h and 44 h after operation separately.
RESULTS(1) In comparison between the result 2 h after operation and that before operation, the levels of CD3+, CD4+ and CD8+ in all of three groups were lower than those before operation. Except that the change in CD4+ in group A did not present significant statistical difference as compared with that before operation (P > 0.05), all of the other differences in T-lymphocyte subgroup indicated statistical significance (all P < 0.05). The ratio of CD4+/CD8+ in three groups was higher than that before operation, but the difference in group A was significant statistically (P < 0.05). In 3 days after operation, the levels of CD3+, CD4+ and CD4+/CD8+ were all higher than those before operation, indicating significant statistical differences (all P < 0.05) except CD4+/CD8+ in group B (P > 0.05). (2) In group A, during operation, the dose of narcotic reduced apparently (P < 0.05). (3) Separately, in 4, 6 and 8 h after operation, the dose of analgesia pumper reduced significantly in group A (all P < 0.05).
CONCLUSIONCompound general anesthesia with meridian points involved can increase pain threshold of human body, reduce the dose of narcotic during operation, alleviate the suppression in body immune regulation due to stress reaction of general anesthesia and operation, prolong the time-effect of postoperative analgesia and explain the specificity of meridian points.

OBJECTIVETo investigate the relationship of (TAAAA)n repeat polymorphism in the promoter of the sex hormone-binding globulin (SHBG) gene and SHBG serum levels to the glucose metabolic status of Chinese polycystic ovary syndrome (PCOS) patients in Shandong province.
METHODSGeneScan method was used to detect and identify (TAAAA)n repeat number (alleles) and genotypes for 156 controls and 157 patients who were divided into normal glucose tolerance without hyperinsulinemia (NIR group) and with hyperinsulinemia (HI group) and abnormal glucose metabolic (AGM) group according to the results of oral glucose test and insulin resistant test; IRMA was used to measure serum SHBG for part of them.
RESULTSFive alleles containing (TAAAA) 6-10 repeats and 14 genotypes including 6/6, 6/7, 6/8, 6/9, 6/10, 7/7, 7/8, 7/9, 7/10, 8/8, 8/9, 8/10, 9/9, 9/10 repeats genotypes were present in the subjects. Genotype distribution of 6/10 repeats genotype is lower in PCOS than that in control, and 8/9 repeats genotype vice versa (P < 0.01); among PCOS subgroups, the eight repeat genotypes in NIR group is more frequent than that in HI group (P < 0.01), and 7/9 genotype distribution in AGM group is higher than that in NIR group and HI group(P < 0.05-0.01). The serum SHBG levels in homozygous genotype groups exhibit a sequence of 8/8 > 9/9 > 6/6, 7/7 repeats and the fall of serum SHBG trend is in reversed relation with the increase in body mass index (BMI), Homa-IR, and blood pressure. Serum SHBG levels in AGM exhibit a sequence of HI group < NIR group < control but show no statistical difference between both groups.
CONCLUSIONThis study reveals that the repeat number, alleles, genotypes and their distributions in Chinese women are very different from these in foreigners. Some special genotypes and low serum SHBG levels may be associated with PCOS and its glucose metabolic status; some special genotypes may influence Chinese serum SHBG and need more studies, but both SHBG gene polymorphism genotype and serum SHBG are not good indicators to find out the PCOS individual at high risk.

OBJECTIVETo compare the immunophenotypic and clinical characteristics between NPM1 mutated acute myeloid leukemia (AML) (NPM1m(+)AML) and unmutated AML(NPM1m(-)AML) not otherwise characterized (NOS) under similar FAB subtypes constituent ratio.
METHODSImmunophenotyping and NPM1 gene mutation type-A, B and D and other leukemic related fusion genes were detected by multiparameter flow cytometry and real time RT-PCR or PCR, respectively. 104 AML patients with NPM1m(+)AML and performed immunophenotyping assay were included, 97 with NPM1m(-)AML.
RESULTSThere were significant difference between the two groups at presentation in terms of sex, white blood count(WBC), platelet counts (PLT), blast ratio, normal karyotype ratio, WT1 expression level, FLT3-ITD mutation positive rate and remission rate of first course of induction therapy (P < 0.05). On the immunophenotype, the expression of early differentiation antigens (CD34, HLA-DR, CD117, CD38), lymphocytic antigens (CD7, CD4, CD19, CD2), myeloid and monocytic differentiation-associated antigens (CD13, CD14, CD15) were lower, and that of CD33 as well as CD123 were higher in NPM1m(+)AML patients. Among them, only CD34, HLA-DR, CD7, and CD4 positive cases were significantly lower in NPM1m(+)AML group than in NPM1m(-)AML group (P < 0.05), the rest of them had significant difference in the number of positive cells (P < 0.05). Above features were further analyzed between the M1/M2 and M4/M5 subgroups. M1/M2 cases retained the women prominent and had a higher WT1 expression level (P < 0.05). The expression of monocytic differentiation-associated antigens including HLA-DR and lymphocytic antigens were higher and that of CD117 were lower in M4/M5 subtype (P < 0.05). Among them, the positive rates of HLA-DR, CD64, CD11b, CD10, CD15, and CD4 were significantly higher in M4/M5 than in M1/M2 in NPM1m(+)AML group (P < 0.05).
CONCLUSIONThe most clinical characteristics in NPM1m(+)AML patients are consistent with reports, but some immunophenotype are different to the previous reports under similar FAB subtypes constituent ratio. The major immunophenotypic features of NPM1m(+)AML patients are lower expression of progenitor, myeloid and lymphoid lineage antigens. Monocytic differentiation-associated antigens are only higher expression in M4/M5 cases when comparison with M1/M2 cases within NPM1m(+)AML group.
