Objective:To explore therapeutic effect of neuromuscular electrical stimulation combined swallowing training in dysphagia after stroke.Methods: A total of 86 stroke patients during recovery period were selected.According to random number table, they were randomly and equally divided into pure training group (received swallowing training based on rehabilitation treatment and nursing care) and combined training group (received neuromuscular electrical stimulation based on routine training group).Therapeutic effects, scores of video fluorography (VFG) and swallowing quality of life (SWAL-QOL) questionnaire before and after treatment were compared between two groups.Results: After treatment, total effective rate of combined training group was significantly higher than that of pure training group (95.35% vs.69.77%, P=0.006).Compared with pure training group after treatment, there was significant rise in VFG score [(5.74±1.86) scores vs.(6.88±2.32) scores], and significant reduction in SWAL-QOL score [(762.66±27.22) scores vs.(648.22±29.62) scores] in combined training group, P=0.025, 0.001 respectively.Conclusion: Compared with swallowing training alone, neuromuscular electrical stimulation combined swallowing training possesses better therapeutic effects, which is better for recovery of swallowing function.

Objective To promote more understanding of bone metastasis and reduce the misdiag-nostic rate of bone metastatic tumor.Methods The mechanism of skeletal metastasis,the spreading pathway of tumor to bone,its frequency and distribution of skeletal metastasis,as well as relative frequency of primary malignant tumor,clinical features,diagnosis and differential diagnosis with bone metastastic tumor were re-viewed.Five misdiagnosed cases as bone metastasis were presented.Results Five cases of patients were ob-tained post-longer time of follow-up examination,ranging from24to96months(average57.6months).Case1was carcinoma of lung,and case2carcinoma of prostatic gland,both were living and well.Case4and case5were tuberculosis of lumbar spine,their conditions were stable and satisfied.A lesion of lum-bo sacral disc in case3was found and diagnosed as infection and kept stable without any back and extremities pain since first attack of disease.The causes of misdiagnosis were analyzed.Conclusion Meticulous review of the history and clinical features as well as proper explanation of the supplemental data from plain X-ray,bone scintigraphy,CT and MRI findings are essential for diagnosis of majority of bone metastatic tumor.Al -though such new imaging devices(as bone scintigraphy,CT and MRI )possess a high sensitivity for early detection of bone metastasis,yet with a poor specificity,hence orthopaedic surgeon have to catch hold of proper understanding about new imaging techniques.In difficult and doubtful cases,the bone biopsy under CT guiding may be needed,the radioisotopic Hawkeye system and diffusion weighted MR imaging are rec-ommended for differential diagnosis of senile acute benign(e.g.osteoporosis)and malignant (e.g.metastasis)vertebral body com pressive fracture.

Objective To investigate the correlation between the arterial compliance and insulin resistance in the prehypertensive people.Methods 30 healthy persons,36 prehypertensive persons and 46 hypertensive patients were measured Cl and C2 using CVProfilor DO-2020 and determined insulin sensitivity with HOMA-IR.Results Adjusted for the age and the course of disease,C1 and C2 decreased in hypertensive patients compared with that of the healthy and prehypertensive people(P<0.05);C2 decreased in prehypertensive people compared with the healthy groups(P<0.05).HOMA-IR increased in hypertensive patients and prehypertensive people compared with the healthy groups(P<0.05).There was significant correlation between HOMA-IR and C2 in prehypertensive people.Conclusion Small arterial compliance decrease and insulin resistance can be found with negatively correlation in prehypertensive people.

Epidemiological studies indicated that dietary tiber was inversely associated with stroke risk.Epidemiological studies have confirmed that increased dietary fiber intake can reduce the risk of stroke.Animal experiments and clinical studies have shown that dietary fiber intake may reduce the incidence of stroke by reducing vascular risk factors,such as hypertension,diabetes,dyslipidemia,and obesity.The direct mechanism of increased dietary fiber intake reducing stroke risk remains to be further studied.Clinicians should pay attention to the important role of dietary fiber,guide the patients with stroke and individuals at risk of stroke to increase consumption of fiber-rich fruits and vegetables.

The rate is 70% with gram staining. Conclusion Staphylococcus aureus L-form DNA had get into laryngocarcinoma ceells, is great possibly to integrate into host ce11, and influence hyperplasis and canceration of cell from gene level. Staphylococcus aureus and its L-form infection have possibly close relation to happen and development of laryngocarcinoma.

The expressions of matrix metalloproteinnse-9 (MMP-9), tissue inhibitor of metalloproteinase-1 (TIMP-1) ,and NF-κB in 157 cases of papillary thyroid cancer and 30 cases of papillary thyroid tumors were detected by immunohistochemistry and in situ hybridization. The expressions of MMP-9 and NF-κB protein and mRNA in papillary thyroid cancers were significantly higher than those in benign tumors (all P <0.01), and increased according to the pathological grading (P<0.01). The expressions of MMP-9 and NF-κB protein and mRNA in papillary thyroid cancers with cervical lymph node metastasis were higher than those without metastasis (both P <0.01). The expressions of TIMP-1 protein and mRNA appeared an opposite direction of MMP-9 expression.

Objective To explore methods of quickly identifying loopholes in medical quality management and to improve medical quality by means of analyzing low-risk death cases.Methods Two rounds of analysis of 1 14 low-risk death cases of hospitals in Beijing in 2012 in terms of data quality and medical procedures,in an effort to identify problems and to verify the feasibility and accuracy of the method through interaction with other data.Results Totally 585 760 inpatients were discharged in 2012 from 21 hospitals,of whom 1 5 1 1 93 being low-risk cases.Such cases included 1 14 low-risk death cases, accounting for 0.01 9% of the total discharged,and 0.075% of low-risk discharged cases.Analysis of these medical records found 50 cases of problematic diagnosis (43.86%),45 cases of possible defects in diagnosis and treatment (39.47%),39 cases of missing items of secondary diagnosis (34.21%),and 28 cases of missing items of surgery/operation (24.56%). Some of the abovementioned cases had overlapping mistakes.Conclusion Analysis of low-risk death cases can help focus among massive data of medical records,problems of diagnostic and therapeutic insufficiency,pinpointing common problems in medical service and improving medical quality and fine management of hospitals.

Ventilatory volumes and respiratory flow rate during quiet and rapid respiration were measured in 480 healthy pilots of our Air Force. The mean values were: VE, 9.58?1.74 1/min; MVV, 154.69?19.48 l/min; PIFR, 23.56?4.60 l/min; and FPIFR, 182.388?29.95 l/min.Regression analysis showed that they correlated well with each other as well as with body surface area (BSA), age, sitting height etc. The regression. formulae are Y = 2.97398 + 3.74173X2 for VE, Y = 103.921-0.839956X1 + 44.4811X2 for MVV, Y = 20.2761+0.735782X4 for PIFR, and Y = 99.9757-0.69924X1+ 59.7506X2 for FPIFR, where X1 stands for age, X2 for BSA, and X4 for vital capacity.The above results should provide a valuable physiological basis for designing aircraft oxygen equipment,for laying down the standard of on-board oxygen supply, and for pulmonary functional tests in pilots.

To investigate the effect of Cornu Cervi Oral Liquid (mainly composed of Cornu Cervi, Fructus Psoraleae, Herba Epimedii, Fructus Corni, Fructus Ligustri Lucidi and Lignum Aquilariae Resinatum) in reversing myocardial fibrosis in rats with congestive heart failure caused by pressure overload and to explore its mechanism. Thirty six male Wistar rats were randomly allocated to mimic operation group (Group A), model group (Group B) and Cornu Cervi Oral Liquid group (Group C). Rat models of congestive heart failure were induced by constriction of abdominal aorta. Left ventricular mass index(LVMI) was observed; contents of collagen type Ⅰ and Ⅲ in left ventricular cardiac muscle were detected by immunohistochemical method and their mRNA expression by RT PCR; and plasma levels of angiotensin Ⅱ (AngⅡ), atrial natriuretic factor (ANF) and serum aldosterone (ALD) level were measured by radioimmunoassay method. LVMI, contents of collagen type Ⅰ and Ⅲ and their mRNA expression, levels of plasma and myocardial AngⅡ, plasma ANF and serum ALD were higher in Group B than those in Group A (P0 05).[Conclusion]Cornu Cervi Oral Liquid is effective in reversing myocardial fibrosis in rats with congestive heart failure caused by pressure overload and its mechanism may be related to the decrease of contents of collagen type Ⅰ and Ⅲ and their mRNA expression, levels of plasma and myocardial AngⅡ, plasma ANF and serum ALD.
