OBJECTIVETo investigate the role of cyclin D1 and p27(kip1) in the occurrence and development of conventional renal cell carcinoma(CRCC).

METHODSRT-PCR and Western-blot were used to detect mRNA and protein contents of cyclin D1 and p27(kip1) in 25 CRCCs and 10 normal renal tissue distant to tumor. Immunohistochemistry was used to investigate the expression of cyclin D1 and p27(kip1) in pathological tissue sections of 76 CRCCs. The relationship between those index and clinicopathological parameters was analyzed statistically.

RESULTIn CRCC, the expression of cyclin D1 was higher than that of the control group. The higher cyclin D1 content was related to big tumor size (P<0.05); The expression of p27(kip1) was lower than that of the control group, and the lower p27(kip1) was related to higher nuclear grade and TNM stage (P<0.01). The 5-year cumulative survival rate of the p27(kip1) high expression group is longer than that of the low group (P<0.01).

CONCLUSIONThe excessive expression of cyclin D1 and lower expression of p27(kip1) play an important role in the carcinogenesis of CRCC. The lower expression of p27(kip1) may affect the progression of the tumors. The detection of p27(kip1) may be as a reference marker in the prognosis of CRCC.

Objective To study the quality of life and its influential factors among HIV positive population. Methods Quality of life was evaluated among 2608 HIV positive population by WHOQOL (Chinese Version) to calculate the total and four domains' scores of quality of life. Multiple linear regression model was used to analyze the relationship between the factors and the scores of the four domains and the total score of quality of life. Results Physical,psychological,social,environmental and the total scores of the HIV positive population were 12.96±1.94,11.79± 1.19,13.79±2.44,12.40±1.93 and 51.02±6.03,respectively. Females had a higher scores than males in the four domains and the total score of quality of life. Through a multiple linear regression model,we found that the influential factors would include gender,age,occupation,family conflict and appetite etc. Conclusion People living with HIV had higher scores in social domain,but lower scores in psychological domain,suggesting that psychological intervention should he strengthened.

OBJECTIVEWe observed the therapeutic effectiveness and safety of different antidepressants as well as the correlation between symptomatic improvement of depression and improvement of chest pain in patients with susceptible "angina pectoris" and negative coronary angiogram complicating comorbid depression.

METHODSIn this double-blinded randomized study, a total of 123 eligible patients were allocated into three groups: (1) Group F: fluoxetine 20 mg QN (n = 41); (2) Group P: Placebo 1 tablet QN (n = 40); (3) Group F + O: fluoxetine 20 mg + olanzapine 2.5 mg QN for the former 2 weeks and only fluoxetine 20 mg QN for the latter 2 weeks (n = 42). The total therapy duration was 4 weeks. HAMD, HAMA and self-evaluation table of chest pain were obtained before therapy, at the end of 1 and 2 weeks after therapy.

RESULTSBaseline HAMD and HAMA scores and self-evaluation score of chest pain were similar among 3 groups and all scores were significantly improved post various therapies in the order of group F + O > group F > group P. The rate of score decrease were seen after 1 week treatment in group F + O and after 2 week treatment in group F. There was a significant positive correlation between the rates of self-evaluation chest pain score decrease and HAMD (r = 0.867, P < 0.001) and HAMA (r = 0.854, P < 0.001) score decreases after 4 weeks therapies (P < 0.05). During the whole course of treatment, no serious adverse reaction was found in all patients.

CONCLUSIONIn patients with suspected "angina pectoris" and negative coronary angiogram complicating comorbid depression, the antidepressants were safe and significantly improved the symptoms of depression and anxiety and chest pain. Low dose fluoxetine plus short term olanzapine regimen was superior to fluoxetine alone regimen in terms of stronger and quicker symptom improvement.

To compare with the effects of the GM-CSF and IL-2 used as adjuvants in the baculovirus vaccine, we used genetic engineering to construct the recombinant baculovirus rBV-LMI-F and with GM-CSF and IL-2 to immunized chickens. Then, we compared the concentration of the neutralizing antibody and cytokines to determine the immunostimulatory effects of GM-CSF and IL-2. GM-CSF induced higher levels of antibodies and cytokines in chickens at 28 d and 42 d post-vaccination. In conclusion, GM-CSF could elicit higher serum antibody and cytokines responses and improved the effects of Baculovirus vaccine.

We aimed to study radiomics approach based on biparametric magnetic resonance imaging (MRI) for determining significant residual cancer after androgen deprivation therapy (ADT). Ninety-two post-ADT prostate cancer patients underwent MRI before prostatectomy (62 with significant residual disease and 30 with complete response or minimum residual disease [CR/MRD]). Totally, 100 significant residual, 52 CR/MRD lesions, and 70 benign tissues were selected according to pathology. First, 381 radiomics features were extracted from T2-weighted imaging, diffusion-weighted imaging, and apparent diffusion coefficient (ADC) maps. Optimal features were selected using a support vector machine with a recursive feature elimination algorithm (SVM-RFE). Then, ADC values of significant residual, CR/MRD lesions, and benign tissues were compared by one-way analysis of variance. Logistic regression was used to construct models with SVM features to differentiate between each pair of tissues. Third, the efficiencies of ADC value and radiomics models for differentiating the three tissues were assessed by area under receiver operating characteristic curve (AUC). The ADC value (mean ± standard deviation [s.d.]) of significant residual lesions ([1.10 ± 0.02] × 10^-3 mm² s^-1) was significantly lower than that of CR/MRD ([1.17 ± 0.02] × 10^-3 mm² s^-1), which was significantly lower than that of benign tissues ([1.30 ± 0.02] × 10^-3 mm² s^-1; both P < 0.05). The SVM feature models were comparable to ADC value in distinguishing CR/MRD from benign tissue (AUC: 0.766 vs 0.792) and distinguishing residual from benign tissue (AUC: 0.825 vs 0.835) (both P > 0.05), but superior to ADC value in differentiating significant residual from CR/MRD (AUC: 0.748 vs 0.558; P = 0.041). Radiomics approach with biparametric MRI could promote the detection of significant residual prostate cancer after ADT.

OBJECTIVE: To explore the clinical effect and adverse reactions of Strychnos nux-vomica in bortezomib-induced peripheral neuropathy (BIPN) of patients with multiple myeloma (MM). METHODS: A total of 19 MM patients with BIPN were enrolled and Nux Vomica Capsule (NVC, 0.4 g, thrice daily) were orally administrated for 30 days. Comparative analysis on parameters between pre- and post-therapy, including peripheral neuropathy (PN) grade, neurotoxicity score, Chinese medicine (CM) syndrome score, total neuropathy score (TNS), coagulation function, and serum nerve growth factor (NGF) levels were conducted. The adverse events were monitored. RESULTS: In BIPN of MM patients who received NVC, PN grade was lowered, neurotoxicity score was obviously decreased (P⩽0.01), and both CM syndrome score and TNS were remarkably decreased (P<0.01). After the therapy, activated partial thromboplastin time was prolonged (P<0.01) and fibrinogen was declined (P<0.05), showing improvement in the hypercoagulable state of patients. No significant difference of NGF recovery degrees was detected between pre- and post-therapy (P>0.05). No evident adverse reactions were observed during the course of treatment. CONCLUSION Strychnos nux-vomica L. has significantly effect with a good safety in treatment of BIPN in MM patients.
