Mantle cell lymphoma (MCL) is a rare subtype of B-cell non-Hodgkin's lymphomas (NHLs). MCL comprises distinct subtypes with different pathological characteristics and clinical features. However, MCL remains incurable by intensified first-line regimens con-taining cytarabine and involving consolidation with high-dose therapy and autologous stem cell transplantation. Recently discovered somatic mutations and aberrant intracellular signaling pathways have been demonstrated to play an essential role in the pathogenesis of MCL. The related novel therapeutics, such as Btk inhibitors, PI3K inhibitors, and immune modulators, have exhibited promising ther-apeutic effects on untreated or even relapsed/refractory MCL. The development of an efficient combination therapy is urgently need-ed to improve the survival of MCL patients in the future.

Objective To investigate the clinical distribution and antibiotic resistance of the nonfermenting bacterial strains isolated in Beijing Anzhen Hospital from 2008 to 2012.Methods The bacteria were identified by VITEK-compact system and Phoenix 100 system. Antimicrobial susceptibiity was tested by dilution method. Results A total of 2 450 strains of nonfermentative gram-negative bacteria were isolated from clinical specimens. Acinetobacter baumannii, Pseudomonas aeruginosa and Stenotrophomonas maltophilia accounted for 57.2%,25.5% and 10.0%.Specimens were mostly collected from respiratory tract (80.9%),followed by blood (8.1%)and wound exudates (3.9%).The strains were mainly collectd from ICU (50.0%),cardiac surgery ward (17.0%)and respiratory medical ward (11.5%).The prevalence of imipenem-resistant A.baumannii was 62.3%,79.2%,70.4%,76.1%,67.8% from 2008 to 2012.The prevalence of imipenem-resistant P.aeruginosa was 28.7%,25.0%,27.6%,31.1% and 32.0%.S.maltophilia strains showed the highest susceptibility to trimethoprim-sulfamethoxazole and levofloxacin.Conclusions The high prevalence of antibiotic-resistant non-fermenting bacteria poses a great challenge to clinicins. The rational treatment choice should be based on the result of suseptibility testing.

Methods Comprehensive educational interventions were practiced at the beginning,middle-term and end of their internship. The Self-Rating Anxiety Scale(SAS)was adopted to assess their level of anxiety.Results There were differences in SAS scores between the three phases(F=2.680,P<0.05).The scores were decreased from the beginning to the end.Conclusion Targeted comprehensive educational interventions can reduce anxiety and stress of nursing students.

Objective To observe the substance P(SP) and calcitonin gene-related peptide(CGRP) expressions in the temporomandibular joints(TM J) of the rats undergone emotional stress and explore the relationship between emotional stress and temporomandibular joint disorder(TMD). Methods Ninety SD rats were averagely randomly divided into emotional stress ( ES ) group( n = 30 ), electric foot-shocked (FS) group ( n = 30 ) and control (CON) group( n = 30). The emotional stress was induced by communication box. The TMJ tissues in ES and CON groups were removed after 1, 3 and 5 weeks of emotional stress for scanning electron microscope ( SEM ) test and immunohistochemistry test. The SP and CGRP expressions were examined with SABC immunohistochemistry and then analyzed by image analysis system. Results The expressions of SP and CGRP had significant difference after 1 ,3 and 5 weeks emotional stress ( SP: 124.5 ± 16.9,185.6 ± 1.8 and 193.5 ± 3.5, respectively; CGRP: 185.9 ±5.3, 112.5 ±5.2 and 174.3 ±5.3 ,respectively) (P＜0. 05 ). The SEM results showed that there was a series of structural change on the condylar surface after emotional stress. Conclusion The SP and CGRP energy nerve fibers take part in the TMJ pathological process undergone emotional stress.

Objective To observe the effects of insulin-like growth factor-2 (IGF2) in the course of mouse embryon-ic stem cells induced to differentiate into islet-like cells. Methods Mouse ES cells were induced to differentiate into islet-like cells in vitro. The expression of islet specific markers was tested by RT-PCR and immunofluorescence assay. RT-PCR/RFLP was used to test the imprinted genes IGF2 parental expression in cells at different stages. Results Islet specific mark-ers were expressed in differentiated cells, such as insulin, glucagon and C-peptide. PCR-RFLP showed that imprinted genes IGF2 derived from embryonic stem cells were biallelic expression and loss of imprinting. Conclusion Gene imprinting sta-tus of IGF2 was changed in differentiated cells in vitro.

Objective To investigate the role of psychological intervention in the prevention of the temporomandibular joint disease (TMD) , through the observation of the relative changes in the rat TMJ under psychological stress after psychological intervention. Methods The rat model of communication box was built to exert the psychological stress. The antianxiety agent was applied before stress, and the stressor was removed after stress. The expression of the proinflammatory cytokines IL-1 and TNF-α in the mandibular condylar chondrocytes in rat TMJ was detected by ELISA and RT-PCR. Results The RT-PCR results showed that the expression of IL-1 mR-NA increased into the peak in the 1st week, weakened in the 3rd week, and returned to normal in the 5th week, while the TNF-αmRNA peaked in the 1st week, returned to normal in the 3rd week. The ELISA results showed that there was no significant difference of the OD value of the serum IL-1 and TNF-α(0. 095 ±0. 006,0. 077 ± 0.007,0.069 ±0.009 ;0.079 ±0.010,0.075 ±0. 009,0.079 ± 0.012) in the antianxiety agent group (0. 107 ± 0.024,0. 101 ±0.005,0.088 ±0.010)and the stressor removal group(0. 090 ±0.016,0. 088 ±0.005,0.089 ± 0.011) , compared with the control group(0.087 ±0.004,0.090 ±0.009,0.089 ±0.010;0.074 ±0.008,0.069 ±0.015,0.068 ±0.011) (P>0.05), while significant differences were observed when compared with the psychological stress group(0.282 ±0.045,0.226 ±0.021,0.092 ±0.002;0. 164 ±0.009,0.123 ±0.013,0.091 ± 0.006) (P<0.05 ). Conclusion Application of the antianxiety agent and stressor removal could effectively counter the influence of psychological stress to TMJ, which provides good experience for the clinical prevention of TMD.

Objective To investigate the occurrence and influencing factors of perimenopausal syndrome (MPS) and natural menopause women age 40-60 years in Guiyang city, with the purpose of providing information for planning care for menopausal women. Methods A convenient sampling was conducted among 40-60 years old healthy women visiting the three Medical Examination Centers of affiliated hospital of Guizhou Medical University, 1594 subjects were interviewed using a self-designed questionnaire. Improved Kupperman Scale was used to evaluate the MPS. Results The percentage of MPS in the 40-60 years old women is 61.60%, of them, the proportion of mild, moderate and severe cases were 38.96%, 21.52% and 1.13% respectively. Mild and moderate account for the most cases. The top 5 symptoms of MPS were:mood agitation (60.85%), wakefulness (58.22%), muscle or joint ache (57.40%) , fatigue (57.09%) and dizziness (48.68%). The incidence of MPS was related to the following factors: age, marital status, degree of education, family monthly income, current menstrual conditions, age of first sexual life and the frequency of pregnancies and deliveries. The occurrence of MPS were associated with age, educational status,family income,current menstruation condition, age of first sexual intercourse and number of pregnancies. As age increases, the severity of MPS arise. With menstrual changes from normal to irregular and menopause, the rate and severity of MPS increased. With the frequency of pregnancies increases, the possibility of moderate and severe degree of PMS increase. The natural menopause age of healthy women in Guiyang was 49.17 ± 3.12. Conclusion The occurrence of perimenopausal syndrome was related to age,current menstruation condition and frequency of pregnancies. Care for perimenopausal period should start as early as possible.
