Peroxiredoxin 1(Prdx1)belongs to peroxide oxidoreductase protein(peroxiredoxin, Prdx)family,which is over-expressed in multiple cancers and it play an important role in antagonizing reactive oxygen species (ROS) therefore as works as anti-oxidations. Its expression is closely related with tumor proliferation, differentiation and metastasis as well as with sensibility to radiotherapy and chemotherapy. Its structure and biological function in tumors and regulation mechanism were reviewed in this paper. It can provide evidence to screen new therapeutic targets in the treatment of tumors.

Background and purpose:Because of the heterogeneity of cancers,different patients with the same kind of cancer have different sensitivity for cytotoxic drugs.Newly developed ATP chemosensitivity assays(ATPTCA) offer the opportunity for individualized therapy and have shown promising results compared to standard regimens.We explored the feasibility of the ATP-Tumor Chemosensitivity Assay(ATP-TCA) applied in the treatment of ovarian cancer with chemotherapy,and evaluate the in vitro sensitivity of fresh specimens of ovarian cancer to five cytotoxic drugs.Methods:ATP-TCA was used to detect the sensitivity rate of 24 fresh specimens of ovarian cancer to five cytotoxic drugs as follows: paclitaxel(TAX),gemcitabine(GEM),doxorubicin(ADM),topotecan(TPT),cisplatin(DDP).Results:23 of 24 specimens((95.83%)) can be evaluated by ATP-TCA,the sensitive rates of ATP-TCA was 91.30% for TAX,86.96% for GEM,65.22% for ADM,47.83% for TPT and 21.74% for DDP,respectively.Conclusions:ATP-TCA was a sensitive、reliable and standardized method for the evaluation of tumor chemosensitivity,it ts worthwhile to investigate further for the application screening anticancer agents in chemotherapy of ovarian cancer.

Objective: To investigate the psychosocial characteristics and mind-physique status of pa-tients with gynecological malignant tumors. Methods: Clinical psycho-rating scale [life event scale (LES) and symptom checklist-90 (SCL-90)] was applied to test life events and mind-physique status of 60 cases of pa-tients with gynecological malignant tumor. The results were compared with those of 40 female patients with benign tumors and 40 normal females. Results: The frequency and tension value of total life events and those of negative life events in the malignant cancer group were much higher than those in the benign tumor group and normal group (P<0.05) and no remarkable differences were found in the frequency of positive life events among the three groups. The frequencies of total life events and negative life events were higher in the be-nign tumor group than those in the normal group (P<0.05) but there were no significant differences in the fre-quency of positive life events, total tension value or positive tension value among the three groups. No signifi-cant differences were found in the indices of SCL-90, positive scores and scorns of other factors among the three groups (P>0.05). The scores of somatization, obsession, interpersonal relationship sensitivity, anxiety, hostility, phobia, and paranoia were higher in the malignant tumor group than in the benign tumor group and normal group (P<0.05). The average positive scores and the depression scores in the benign tumor group were higher than those in the normal group (P<0.05), but there was no statistical significance in other indices between the benign tumor group and the normal group (P>0.05). Conclusion: Negative psychosocial factors are closely correlated with the occurrence and growth of gynecological malignant tumors. Active psychological intervention should be performed as eady as possible.

ObjectiveTo study the relationship between mental symptoms and the social functioning of outpatients with schizophrenia.Methods93 outpatients with schizophrenia received tests of Positive and Negative Syndrome Scale(PANSS) and Morningside Rehabilitation Status Scale(MRSS).ResultsThe total score of MRSS,the score of Dependency Scale(DEP),Inactivity Scale(INACT) and Social Isolation Scale(ISOL) had positive correlation with scores of PANSS,Positive Subscale,Negative Subscale and General Psychopathology Subscale(P<0.01).ConclusionsThe social functioning of outpatients with schizophrenia has close correlation to their mental symptom,the more plentiful the mental symptom is,the more serious the social functioning damage is.

ObjectiveTo investigate the effect of whole-period psychiatric rehabilitation on outpatients with schizophrenia.Methods90 outpatients with schizophrenia were randomly divided into the study group and control group with 45 cases in each group. All cases in two groups received pharmacotherapy, but cases of study group were added with whole-period psychiatric rehabilitation. Assessments were performed before and after study. All subjects were evaluated with the Brief Psychiatric Rating Scale (BPRS) and Social Disability Screening Schedule (SDSS).ResultsThe outcome of the study group was significantly superior to the control group on overall improvement according to the reductions of BPRS score, Anergia factor score, thought disturbance factor score, suspiciousness factor score and SDSS score(P<0.05-0.01).ConclusionThe whole-period psychiatric rehabilitation may play an important role in controlling symptoms and improving social function to outpatients with schizophrenia.

ObjectiveTo investigate the family adaptability, cohesion and their relationship with symptoms of chronic outpatients with schizophrenia.Methods51 outpatients with schizophrenia were assessed with Family Adaptability and Cohesion Scales, Second Edition, Chinese Version(FACE II-CV) and Positive and Negative Syndrome Scale(PANSS ).ResultsThe level of family adaptability of chronic outpatients with schizophrenia was lower than that of the normal control(u<0.05 or u<0.01);the ratio of the balance category of family decreased significantly and that of the extreme category of family increased significantly;the score of real cohesion negatively correlated with scores of PANSS, Positive Subscale and General Psychopathology Subscale (P<0.05);the score of real adaptability negatively correlated with score of Positive Subscale (P<0.05). ConclusionsFamily adaptability and cohesion of outpatients with schizophrenia close correlate to symptoms of chronic outpatients with schizophrenia and level of family adaptability decreases.

ObjectiveTo study the effects of the Behavior Therapy on outpatient with schizophrenics in relieving symptoms, insight, and attitude to treatment. Methods96 outpatients with schizophrenia were randomly assigned to the Behavior Therapy group and the control group. The Behavior Therapy courses were given to the Behavior Therapy group for six months. All the subjects were evaluated with Positive and Negative Syndrome Scale(PANSS) and Insight and Therapeutic Attitude questionaire(ITAQ). Results94 cases completed the trial. The scores of PANSS, the Negative Subscale, the General Psychopathology Subscale of the Behavior Therapy group decreased significantly after treatment(P<0.01). The score of ITAQ of the Behavior Therapy group increased significantly after treatment(P<0.01).The reductions of PANSS, the Positive Subscale, the Negative Subscale, the General Psychopathology Subscale and ITAQ between two groups were significant different(P<0.05-P<0.01). Conclusions The Behavior Therapy may play an important role in augmenting optimal pharmacotherapy for outpatients with schizophrenia and it is effective in improving symptoms, insight and therapeutic attitude.

Objective: To identify appropriate ways of applying the current cervical screening methods to minimize the occurrence of missed diagnosis of high-grade cervical intraepithelial neoplasia (CIN2/3) and cervical cancer. Methods: A retrospective analysis was conducted based on the clinical data of 318 patients, who had CIN2/3 or cervical cancer and were treated in Aviation General Hospital Affiliated to China Medical University between June 2014 and August 2018. Among these cases, 296 involved CIN2/3, and 22 involved cervical cancer. All of the patients involved underwent a thinprep cytology test (TCT) and high-risk human papilloma virus (hrHPV) screening, and their age and TCT and hrHPV results were further analyzed. Results: Among the 296 patients diagnosed with CIN2/3, 130 of them (43.92%) were aged between 30 and 39 years, ranking the top among all age groups. Sixty-nine young patients (23.31%) aged between 20 and 29 years were diagnosed with CIN2/3, ranking in the third place. Among all of the 318 cases, the TCT results were positive in 199 cases (62.58%), hrHPV results were positive in 308 cases (96.86%), and there were 313 cases (98.43%, 313/318) wherein both TCT and hrHPV results were positive according to joint screening. The most predominant hrHPV subtypes were 16, 52, 58, 33, 18, and 31. Conclusions: As an increasing number of young women are diagnosed with CIN2/3 and cervical cancer, their screening should not be ignored. Single use of TCT screening leads to more frequent missed diagnosis of high-grade lesions compared with single use of hrHPV screening, while joint use of both screening methods could improve the detection rate. Even if TCT results were negative, it is suggested to conduct a colposcopy for those patients with high-risk subtypes besides hrHPV16 and 18 positivity, and in particular, for patients with hrHPV 52,58,33, and 31 positivity.
