OBJECTIVETo investigate the anxiety disorders and influence factors that occur in adolescent patients with cleft lip and palate and to provide theoretical foundation for mental intervention.
METHODSA total of 120 adolescent patients with cleft lip and palate were investigated using a general information questionnaire, the self-rating anxiety scale, and the social support rating scale (SSRS). The influence factors of anxiety disorders were analyzed.
RESULTSThe effective questionnaires were 119. The occurrence rate of anxiety disorder in adolescent patients was 49.6% (59/119), and the occurrence rates of mild, moderate, and severe anxieties were 41.2% (49/119), 7.6% (9/119), and 0.8% (1/119), respectively. The gender, residential area, disease category, family status (one child or no children), and incidence rate of anxiety disorder in patients were statistically different (P<0.05). The SSRS scores of patients with anxiety disorder were lower than those of patients without anxiety disorder (P<0.05). Multiple regression analysis showed that gender and social support were predictive factors of the occurrence of anxiety disorder (R=0.318).
CONCLUSIONA high anxiety disorder rate occurred in adolescent patients with cleft lip and palate. dender and social support were important influencing factors for anxiety disorder. In the after-mental intervention, considerable attention should be given to the anxiety disorders of patients and improve their mental health.

Stress cardiomyopathy is an atypical myocardial disease induced by emotional or physical stress, with the characteristic of left ventricular systolic dysfunction, transient imaging and electrocardiogram (ECG) changes. Sudden cardiac death can occur in severe cases. Clinical symptoms are likely to appear on acute myocardial infarction, but the exact pathological mechanism is unclear. In the present study, we perform a systematic review of the literature on the clinical manifestations, epidemiological characteristics, ECG, imaging and laboratory tests of stress cardiomyopathy, in order to provide the values for forensic pathology diagnosis.

BACKGROUNDIn cardiology, it is controversial whether different therapy strategies influence prognosis after acute coronary syndrome. We examined and compared the long-term outcomes of invasive and conservative strategies in patients with non-ST-segment elevation myocardial infarction (NSTEMI) and characterized the patients selected for an invasive approach.
METHODSA total of 976 patients with acute NSTEMI were collected from December 2006 to October 2012 in the First Affiliated Hospital of Dalian Medical University Hospital. They are divided into conservative strategy (586 patients) and invasive strategy (390 patients) group. Unified follow-up questionnaire was performed by telephone contact (cut-off date was November, 2013). The long-term clinical events were analyzed and related to the different treatment strategies.
RESULTSThe median follow-up time was 29 months. Mortality was 28.7% (n = 168) in the conservative group and 2.1% (n = 8) in the invasive management at long-term clinical follow-up. The secondary endpoint (the composite endpoint) was 59.0% (n = 346) in the conservative group and 30.3% (n = 118) in the invasive management. Multivariate analysis showed that patients in the conservative group had higher all-cause mortality rates than those who had the invasive management (adjusted risk ratio [RR] = 7.795; 95% confidence interval [CI]: 3.796-16.006, P < 0.001), and the similar result was also seen in the secondary endpoint (adjusted RR = 2.102; 95% CI: 1.694-2.610, P < 0.001). In the subgroup analysis according to each Thrombolysis in Myocardial Infarction risk score (TRS), log-rank analysis showed lower mortality and secondary endpoint rates in the invasive group with the intermediate and high-risk patients (TRS 3-7).
CONCLUSIONSAn invasive strategy could improve long-term outcomes for NSTEMI patients, especially for intermediate and high-risk ones (TRS 3-7).

AIMTo investigate the expression of Spindlin 1 (Spin 1) isoform2 and assess its function in mouse testis.
METHODSFirst, reverse-transcription polymerase chain reaction (RT-PCR) was used to determine whether Spin1 isoform2 is present in mouse testis. Then the expression patterns of the isoform between newborn and adult mice testes were compared by immunoblot analysis. Finally, the diversity of its localization in mice testes at different ages (days 0, 7, 14, 21, 28 and 60) was observed by immunohistochemistry. The localization of the protein in mouse sperm was also investigated by immunofluorescence.
RESULTSThe RT-PCR results show that Spin1 isoform2 is present in mouse testis. As shown by immunoblot analysis, the isoform was more highly expressed in adult testes compared with newborn testes. Interestingly, Spin1 isoform2 did not show up in the cytoplasm of primary spermatocytes until day 14. Also, the protein exists at the tail of the mouse sperm.
CONCLUSIONSpin1 isoform2 is a protein expressed highly in adult testis, which might be involved in spermatogenesis and could be necessary for normal sperm motility.

Hypoxia in bone marrow is suitable for the perfect preservation of biological functions of bone marrow hematopoietic stem cells (BM HSC). It is deserved to study whether the biological functions of BM HSC are influenced when being exposed to environment of oxygen at various concentration during amplification of BM HSCs in normal oxygen condition in vitro and process of peripheral blood hematopoietic stem cell transplantation (PBSCT). This study was purposed to investigate the effects of various oxygen concentrations on biological functions of human BM HSCs. The BM HSCs were amplified in vitro, the amplification level of CD34(+) HSCs and CD34(+)AC133(+) HSCs were detected by flow cytometry, the apoptosis and cell cycle distribution of CD34(+) HSCs amplified in various oxygen concentrations were assayed by flow cytometry with Annexin V/PI double staining as well as PI and Ki-67 antibody, respectively, the differentiation of amplified CD34(+) HSCs in vitro was determined by direction differentiation assay, the migration ability of amplified CD34(+)AC133(+) HSCs was measured by migration test. The results indicated that the oxygen environment below normal oxygen, especially hypoxia, could amplify more primitive CD34(+)AC133(+) HSCs and CD34(+) HSCs with activity, arrest more HSCs in G₀/G₁ phase, promote the generation of BFU-E, CFU-GM, CFU-GEMM, and better preserve the migration ability of HSCs. While the above functional indicators of BM HSCs were poor when HSCs exposed to normoxia, oxygen-unstable and oxygen-severe changeable environments. It is concluded that the biological functions of BM HSCs in PBSCT are related with oxygen concentration and its stability, the culture of BM HSCs in lower oxygen environment may be more beneficial for PBSCT.
