Objective To investigate the anxiety status of male partner involved in induced abortion and to analyze influencing factors related.Methods Male partners of the patients undergoing induced abortion in the gynecology and obstetrics department of a hospital in Kunming in April and May in 2015 were selected and a questionnaire survey was conducted.Self-rating Anxiety Scale (SAS) was used to measure the anxiety status and SPSS 17.0 was used for statistical analysis.Results A total of 53 out of 205 male partners were found to have anxiety symptoms (25.9％),with 44 cases of mild anxiety (21.5％),8 cases of moderate anxiety (3.9％) and 1 case of severe anxiety (0.5％).The main related risk factor was times of pregnancy (OR=3.35) while the protective factors were level of education (OR =0.60),times of induced abortion (OR =0.20) and age (OR =0.32) Conclusion When abortion occurs,the male partner's anxiety appears,mainly with mild and moderate one,and female's emotion are also affected.It is important to strengthen health education and popularize contraceptive knowledge so as to reduce the incidence of anxiety.

Objective To investigate the effects of low dose of extracellular histone on endothelial cells in infectious diseases such as sepsis. Methods The endothelial cells were treated with 10 μg/mL recombinant human histone H3/H4 complex in replacement of calf thymus histones (CTH) for various periods of time, and the morphology changes and the viability of the endothelial cells were recorded. In addition, flow cytometry was applied to identify the characteristics of endothelial cells and enzyme-linked immunosorbnent assay (ELISA) was used to detect the extracellular histones level in endothelial cells culture. Results The low dose of CTH could continuously induce endothelial cells death, cell morphological changes and function loss, which was reproduced by 10 μg/mL recombinant histone H3/H4 complex. Results of histones quantitation showed that histone can cause a series of intracellular reactions in a short period of time. Conclusions It is showed that 10 μg/mL H3/H4 can induce the toxicity in infectious disease and this level of the dose is a lower than those used in previous studies and more close to the pathological conditions.

Objective To analyze the clinical features of the hospitalized children with laboratory-confirmed influenza in Suzhou. Methods The demographic information, laboratory test results, clinical features, treatments and outcomes of the hospitalized children with laboratoryconfirmed influenza were collected retrospectively. The data were analyzed using chi square test,Cochran-Armitage trend test. Results Four hundred and eighty hospitalized children were diagnosed with laboratory-confirmed influenza during the period of 2005 to 2009. Among these cases, 414 were subtype A and 66 were subtype B. The positive rate was 2.66%. Four hundred and nineteen cases (87.29 %) were ≤ 5 years old. Most of the cases developed during winter (from December to April the next year) and summer (from July to August). The age and sex distribution didn't vary from year to year (x2=9. 7768,x2 = 8. 7573; both P＞0.05). The mean disease course was (16.22± 9.41)days, and the mean hospitalization duration was (7.89 ±2.97) days. The percentages of patients with symptoms of fever, dyspnea and diarrhea or requiring oxygen treatment decreased with age (Z =4. 9430, Z=2. 1021, Z=3. 2073 and Z=2. 3277, respectively; all P＜0.05). The percentages of cases with concomitant pneumonia and upper respiratory infection also decreased with age (Z =-3. 8762 and Z=-3. 5095, respectively; both P＜0.01). Fifteen point five percent (60/387 cases)of the cases were co-infected with pneumococcus and 15. 0% (72/480 cases) were co-infected with respiratory syncytial virus (RSV). The level of C-reactive protein was significantly higher in cases with bacterial co-infection than those with viral co-infection (Z= -3.1290, P ＜ 0. 01 ).Conclusions Hospitalized children with influenza are more common in winter and summer in Shuzhou.Many patients are co-infected with pneumococcus or RSV. The symptoms are more severe in younger children.

Objective To establish a flow cytometric measurement of detecting minimal residual disease(MRD) according to the leukemia-associated immunophenotypes in children with acute lymphoblastic leukemia(ALL) and to explore the significance of MRD detection in ALL children for a individualized treatment. Methods A variety of four-color fluorescent antibody combinations were used to investigate the children's normal bone marrow. The normal bone marrow pattern at two-parameter plots was established to identify the residual tumor cells, seventy-five bone marrow samples from newly diagnosed ALL children were analyzed with four-color cytometry to determined the optimal combinations which can clearly distinguish the tumor cells from normal cells. The bone marrow samples were monitored with the combination panel in 60 patients at the end of induction therapy and follow-up treatment. Cytomorphology test, PCR amplification of 29 fusion genes as well as IgG and TCR gene rearrangements were performed simultaneously. Results Sixty-nine cases (92.0%) could be identified for effective antibody combinations to monitor MRD by four-color cytometry. Fusion genes or IgG and T cell receptor (TCR) gene rearrangements can be detected in 21 cases (28.0%) to monitor MRD by PCR. No MRD can be detected in 25 bone marrow samples at the end of induction therapy and follow-up treatment. Four-color cytometry could detect as low as 0.021%-4.130% residual leukemia cells. Conclusion MRD can be monitored by flow cytometry which is faster than PCR, and the sensitivity is superior to morphology method.

There are millions of patients with taxane-induced peripheral neuropathy （TIPN）， and there is no effective treatment or prevention measure in clinical practice. The occurrence of TIPN may be related to the dosage form of paclitaxel drugs， genetic and molecular markers， drug dosage and chemotherapy cycle， patient factors， etc. At present， drugs for treating TIPN mainly include those that inhibit axonal degeneration （such as dosazosin， tamsulosin）， prevent mitochondrial dysfunction （such as glutathione trisulfides， antioxidants α -lipoic acid）， improve calcium imbalance in the internal environment （Shaoyao gancao decoction， N-type voltage-gated calcium channel inhibitor IPPQ）， and inhibit neuroinflammation （such as chemokine inhibitors and selective interleukin-8 receptor inhibitors DF2726A）. Further exploration of drug treatment strategies targeting different induction mechanisms is expected to become a new direction for precise clinical prevention and personalized treatment of TIPN.
