BACKGROUND: While emotional distress, encompassing anxiety and depression, has been associated with negative clinical outcomes, its impact across various clinical departments and general hospitals has been less explored. Previous studies with limited sample sizes have examined the effectiveness of specific treatments (e.g., antidepressants) rather than a systemic management strategy for outcome improvement in non-psychiatric inpatients. To enhance the understanding of the importance of addressing mental health care needs among non-psychiatric patients in general hospitals, this study retrospectively investigated the impacts of emotional distress and the effects of early detection and management of depression and anxiety on hospital length of stay (LOS) and rate of long LOS (LLOS, i.e., LOS >30 days) in a large sample of non-psychiatric inpatients. METHODS: This retrospective cohort study included 487,871 inpatients from 20 non-psychiatric departments of a general hospital. They were divided, according to whether they underwent a novel strategy to manage emotional distress which deployed the Huaxi Emotional Distress Index (HEI) for brief screening with grading psychological services (BS-GPS), into BS-GPS ( n = 178,883) and non-BS-GPS ( n = 308,988) cohorts. The LOS and rate of LLOS between the BS-GPS and non-BS-GPS cohorts and between subcohorts with and without clinically significant anxiety and/or depression (CSAD, i.e., HEI score ≥11 on admission to the hospital) in the BS-GPS cohort were compared using univariable analyses, multilevel analyses, and/or propensity score-matched analyses, respectively. RESULTS: The detection rate of CSAD in the BS-GPS cohort varied from 2.64% (95% confidence interval [CI]: 2.49%-2.81%) to 20.50% (95% CI: 19.43%-21.62%) across the 20 departments, with a average rate of 5.36%. Significant differences were observed in both the LOS and LLOS rates between the subcohorts with CSAD (12.7 days, 535/9590) and without CSAD (9.5 days, 3800/169,293) and between the BS-GPS (9.6 days, 4335/178,883) and non-BS-GPS (10.8 days, 11,483/308,988) cohorts. These differences remained significant after controlling for confounders using propensity score-matched comparisons. A multilevel analysis indicated that BS-GPS was negatively associated with both LOS and LLOS after controlling for sociodemographics and the departments of patient discharge and remained negatively associated with LLOS after controlling additionally for the year of patient discharge. CONCLUSION Emotional distress significantly prolonged the LOS and increased the LLOS of non-psychiatric inpatients across most departments and general hospitals. These impacts were moderated by the implementation of BS-GPS. Thus, BS-GPS has the potential as an effective, resource-saving strategy for enhancing mental health care and optimizing medical resources in general hospitals.

[A BSTR ACT] OB J ECTI V E To i mprove the recognization of clinical, imaging and pathological characteristics of angioleiomyoma (ALM) in the head and neck region. METHODS We retrospectively reviewed the data of 20 patients with ALM in the head and neck region between 2000 and 2012. RESULTS Seven male and 13 female patients were included in this study. The average age was 52.5 (from 28 to 74 years). The symptom in most cases (n=14) was the painless mass, 4 tumors originating in the nasal cavity presented with nasal obstruction or (and) epistaxis, and the other 3 cases were accidentally found by physical examination. The results of B-ultrasonography in 10 ALM cases of subcutaneous or deep space were homogeneously hypoechoic echo texture, straight and linear vessels in the tumor with convergence to one point with a circumscribed margin. MRI in 5 cases demonstrated typically a well-defined mass, which showed hypointensity or isointensity to muscle on T1WI, and heterogeneous hyperintensity on T2WI. All lesions showed obviously delayed enhancement on contrast MRI. HE stain showed that the tumors were formed by bundles of spindle-shape smooth muscle cells circumscribing numerous slit-like blood vessels in most cases. Immunoperoxidase staining revealed that the tumor cells were strongly positive for calponin, desmin and smooth muscle actin (SMA) in the cytoplasm of the smooth muscle cells. The positive expression of progestogen receptor and estrogen receptor was seen in 7 cases and 4 cases respectively among 10 cases. All patients underwent surgery, and recovered well postoperatively without recurrence or malignancy. CONCLUSION The clinical manifestations of ALM are nonspecific. ALM has distinctive imaging features in B-ultrasonic and MRI examination. Histological examination and immunoperoxidase staining can make a definite diagnosis of the disease. Progestogen receptor and estrogen receptor can be expressed in ALM. The postoperative prognosis is good.

The discovery of induced pluripotent stem cells(iPSCs) is a promising advancement in the field of regenerative medicine. Previous studies have indicated that the teratoma-forming propensity of iPSCs is variable; however, the relationship between tumorigenic potential and genomic instability in human iPSCs (HiPSCs) remains to be fully elucidated. Here, we evaluated the malignant potential of HiPSCs by using both colony formation assays and tumorigenicity tests. We demonstrated that HiPSCs formed tumorigenic colonies when grown in cancer cell culture medium and produced malignancies in immunodeficient mice. Furthermore, we analyzed genomic instability in HiPSCs using whole-genome copy number variation analysis and determined that the extent of genomic instability was related with both the cells' propensity to form colonies and their potential for tumorigenesis. These findings indicate a risk for potential malignancy of HiPSCs derived from genomic instability and suggest that quality control tests, including comprehensive tumorigenicity assays and genomic integrity validation, should be rigorously executed before the clinical application of HiPSCs. In addition, HiPSCs should be generated through the use of combined factors or other approaches that decrease the likelihood of genomic instability.

BACKGROUND AND OBJECTIVEThe aim of this study is to evaluate diagnostic yield and the safety of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in the diagnosis ofbronchogenic carcinoma.

METHODSBetween July, 2009 and February, 2010, 95 patients with mediastinal/hilar lymphadenopathy and/or intrathoracic peritracheal or peribronchial masses previously detected with CT scan underwent EBUS-TBNA. No rapid onsite cytology was performed.

RESULTSIn all 95 patients, 60 cases were newly diagnosed lung cancer through the pathological examination and clinical follow-up certification. In 60 lung cancer cases, 112 samples were obtained from lymph nodes (LNs) and 11 samples were obtained from intrapulmonary lesions. Fifty-eight cases of patients were diagnosed, false negative in 2 cases. Sensitivity and specificity of EBUS-guided TBNA method in distinguishing benign from malignant LNs or thoracic masses were 96.67% and 100%, respectively. There was any major complication in this series, the procedure was uneventful.

CONCLUSIONEBUSTBNA seemed a safe and effective technique in making bronchogenic carcinoma diagnosis for mediastinal/hilar LNs and intra-pulmonary masses.

Objective To explore the strategy and outcomes of surgical treatment of thoracic ossification of ligamentum flavum(OLF),especially combined with ossification of posterior longitudinal ligament,thoracic kyphosis and epidural adhesion.Methods Fifty-three cases of thoracic OLF from January 2003 to December 2009 were reviewed retrospectively.All patients were treated by the methods of en bloc resection of semi-facet and lamina.All patients were followed up for more than half an year,including 32 males and 21 females,aged from 43 to 73 years(average 54.7 years).The lesions located in upper thoracic for 18 patients,and in thoracolumbar for 35 patients.For multi-level or jumping OLF patients,the responsible levels were determined by combination of images and clinical symptoms.For multi-level OLF with ossification of posterior longitudinal ligament(OPLL)or thoracic kyphosis(＞50°),multi-level pedicle screw fixation and correction of kyphosis were performed.For dural adhesion patients,part of cerebrospinal fluid was released with a caudal incision of dural sac resulting in collapse and epidural arachnoid separation.Ossific and adhesion dura mater were removed with integrity of arachnoid.The surgical outcomes were evaluated with preoperative and postoperative thoracic Japanese Orthopaedic Association(JOA)score,Nurick grade and neurologic functional recovery ratio.Results Fifty-three cases were followed up for 6 months to 6 years,with an average of 18 months.The average preoperative JOA score was 4.3±2.3,which significantly increased to 8.3±1.8 after operation.Postoperative neurologic functional recovery rates were 11% to 80%(average 65.8%),including excellent in 18 cases,good in 20,fair in 10,and poor in 5.The excellent or good rate was 71.7%.The mean preoperative Nurick grade was 3.7(2-5 grade)and decreased to 2.3 grade after operation.Conclusion En bloc resection of semi-facet and lamina is a safe and effective method for treatment of thoracic OLF.For the patients with OPLL or kyphosis,pedicle screws fixation and kyphosis correction was beneficial for recovery of neurologic function of thoracic OLF patients.

OBJECTIVE: To investigate the effect of hyperbaric oxygen therapy to different degrees of hearing loss and different types of threshold curve in sudden deafness patients, and establish a personalized therapy, so as to promote clinical effect to sudden deafness. METHOD: One hundred and twenty cases were divided into two groups respectively (each group 60 cases). Drug treatment had been used in group A for two weeks. The patients in group B received drug treatment combined with hyperbaric oxygen therapy for two weeks. According to the different degrees of hearing loss and the types of audiogram in two groups, the statistical analysis to the difference of hyperbaric oxygen therapeutic effect was done. RESULT: The effective rates was statistically different (chi2 = 8.044, P < 0.01) between group A (60.00%, 36/60) and group B (83.33%, 50/60). There was no statistical difference between two treatment program in mild and the profound deafness patients. The statistical difference could been found between moderate and the severe deafness, the value of chi2 and p were 4.969, 5.560 and 0.040, 0.035, respectively. In group A, the statistical difference could only been found between mild and the profound deafness patients (chi2 = 6.739, P < 0.05). In group B, the statistical difference could been found in mild and the profound deafness, the moderate and the profound deafness, the severe and the profound deafness patients. The value of chi2 were 11.500, 15.058,10.221 and P < 0.01 respectively. The effective rates was no statistical difference in two treatment programs in the upsloping audiogram and the profound deafness. The statistical difference could been found between the downsloping and the flat audiogram, with the value of chi2 and p were 5.144 and 5.969, P < 0.05, respectively. In group A, the statistical difference could been found between the ascending and descending audiogram, the ascending and the flat audiogram,the ascending type and the profound deafness. The value of chi2 were 6.188, 7.247, 8.082 and P < 0.05, respectively. No statistical difference could been found among the other types of audiogram. In group B, no statistical difference could been found among all types of audiogram. CONCLUSION The effect of hyperbaric oxygen therapy varies with degree of hearing loss and audiogram type. Drug treatment combined with HBOT can promote clinical effect for patients in moderate deafness and severe deafness, the descending and flat type of audiogram.
