BACKGROUND: Inhaled glucocorticoids(IGC) are powerful anti_inflammatory agents used in the treatment of asthma. But it is still uncertain whether long-term use of the IGC affects bone metabolism in asthmatic patients, especially women.OBJECTIVE: To investigate if the prolonged treatment with IGC to Chinese asthmatic woman has a detrimental effect on bone mass and metabolism.DESIGN: A matched controlled study based on the patients SETTING:Clinical Laboratory and the Department of Respiratory Medicine, First Affiliated Hospital, Nanjing Medical University.PARTICIPANTS: From February 1998 to February 2002, forty female Chinese patients with bronchial asthma, regularly followed up at our outpatient clinic, all in the Nanjing area, none of them having a history of chronic systemic GC use, agreed to take part in the study, were selected and divided into two groups: therapeutic group (IGC group): 20 asthmatic women, aged 18-63 years, 5 menopausals, received IGC therapy regularly for at least 5 months; Control group: 20 asthmatic women, aged 18-60 years, 5 menopausals, never received IGC received conventional bronchodilators . They were matched individually for sex, age and menopausal status.METHODS: Bone mineral density (BMD) at the lumbar spine (2-4),femoral neck, trochanter, ward's triangle and total body of femur were measured by dual energy X-ray absorptiometry, BMD were expressed as a absolute value and a T score considered as a SD from peak bone mass respectively. Meanwhile, BMD was also expressed as a percentage (%), which was defined by comparing the BMD absolute value of subjects and BMD normal value of isosexual age cohorts. Osteocalcin and some other markers of bone metabolism were measured by radio immunoassay in two groups.daily dose and accumulative total dose of IGC and BMD in the IGC group.RESULTS: There were no significant difference between two groups in BMD and T score (including the lumbar spine (2-4), femoral neck,trochanter, ward' s triangle and total body of femur) (P ＞ 0.05). There were also no significant correlation between daily dose of IGC and BMD of above 5 parts in the IGC group (r=-0.325 to -0.1102, P ＞ 0.05). But,there were significantly negative correlation between the accumulative total dose of IGC and BMD at lumbar spine2-4,femoral neck and ward's triangle(r=-0.495 ,-0.517,-0.531 ,P ＜ 0.05).There were no significant correlation between the accumulative total dose of IGC and T score of above 5 parts in the IGC group (r=0.443to 0.295 ,P ＞ 0.05). There was negative correlation between the age and the BMD at ward's triangle in the IGC group(r=-0.506,P ＜ 0.05). However ,BMD at 5 locus were not correlated with the age in control group (r=-0.079 to 0.326, P ＞ 0.05).Osteocalcin and some other markers of bone metabolism were no significant difference between two groups (P ＞ 0.05).CONCLUSION: The data suggests that there is no significant influence of IGC on bone mineral density and bone metabolism in asthmatic women,but if continuing exposures to high doses over many years,there may be a detrimental effect on bone mass and metabolism in women, especially elder or postmenopausal asthmatic women treated with IGC who may be more susceptible to any bone mineral loss caused by IGC.

ObjectiveTo explore effects of food viscosity and sex on hyoid motion during swallowing in normal elder.MethodsVideofluoroscopic studies were done in 60 healthy elder. Hyoid motion during swallowing food with different viscosity was measured.ResultsOlder male had longer movement duration, greater amplitudes of upward and forward movement than older female (P<0.05). Amplitudes of upward movement in jam thick swallow and bread thick swallow were greater than that in liquid swallow (P<0.01). Bread thick swallow had the longest movement duration; liquid swallow had shortest movement duration.ConclusionThe hyoid bone moves both upward and forward during swallowing, the amplitude of upward displacement is highly variable and influenced by food viscosity. The duration and amplitude of hyoid motion in male or female are different.

Objective To investigate effects of high fat-salt diet on change of growth and development,body fat distribution insulin sensitivity and associated metabolic indexes for juvenile rats. Methods 50 grams of male,female SD juvenile rats (3 weeks,just weaned) were randomly divided into 3 groups,12-14 animals in each group,were given routine diet (NC) and high fat diet (FC) and high fat-salt diet (FSC) .Then the body weight,,body length,abdominal circumference,blood pressure,visceral fat weight,plasma lipids were measured 4 weeks later,at the same time oral glucose tolerance test and insulin release test were performed. Results In the FSC group,body weight,abdominal circumference,blood pressure,visceral fat,plasma glucose and insulin level significantly increased than the NC group,plasma lipid disorders increased and significant insulin resistance occurred. Conclusion High fat and high salt could successfully induced obesity,hypertension,dyslipidemia and impaired glucose tolerance.

To compare the clinical features and prognosis in patients with cytomegalovirus pneumonia from other pneumonia after allogeneic hematopoietic stem cell transplantation (allo-HSCT). A total of 118 patients with pulmonary complications after allo-HSCT from March 2016 to June 2019 were analyzed retrospectively, who were divided into cytomegalovirus (CMV) pneumonia group ( n=34) and the non-CMV pneumonia group ( n=84). Compared with non-CMV pneumonia group, CMV pneumonia group presented earlier median onset time (1.8 vs.6.0 months, P=0.015) after allo-HSCT, more dyspnea (41.2% vs. 19.0%, P=0.012), hypoxemia (38.2% vs. 13.1%, P=0.006), and interstitial pneumonia (82.4% vs. 23.8%, P<0.01).The incidence of CMV-viremia and serum viral load in CMV pneumonia group were significantly higher than those in non-CMV pneumonia group. Consistently, and the development of mixed infection in CMV pneumonia group was higher than that of non-CMV pneumonia group (41.2% vs. 16.7%, P=0.013). The median follow-up time was 12.8 (0.4-46.5) months. The 1-year attributable mortality in CMV pneumonia group was significantly higher than that in non-CMV pneumonia group (26.5% vs. 10.7%, P=0.004), while the 1-year overall survival rate was significantly lower than that in non-CMV pneumonia group (61.8% vs. 85.7%, P=0.001). Reduced-intensity conditioning (RIC)( P=0.036), high flow ventilation ( P=0.033) and negative CMV-viremia ( P=0.009) were unfavorable prognostic factors of patients with CMV pneumonia. Compared with those with non-CMV pneumonia, patients with CMV pneumonia had more characteristic clinical manifestations and imaging features. However, due to the higher incidence of mixed infections, the causes of pneumonia need to be identified by bronchoscopic alveolar lavage. In conclusion, patients with CMV pneumonia have worse clinical outcome. RIC, high flow ventilation and negative CMV-viremia are adverse prognostic factors for CMV pneumonia.

Objective To evaluate the clinical outcome of external bracket fixation in the treat- ment of complex tibia diaphysis fracture involving intra-articular fractures.Methods Forty-two cases of complex tibia diaphysis fracture with proximal and distal intra-articular fractures treated surgically in our hospital from January 1999 to January 2004 were analyzed.The complex tibia diaphysis fractures were categorized according to the AO classification as type C2 (multiple segments fracture) and type C3 (ir- regular fracture),proximal and distal intra-articular fractures in 23 and 19 cases,respectively.Definite operation was done within one week.Twenty-two cases were treated with simple external fixator,and 20 cases treated with screws and external fixator.Results All the 42 cases were followed-up regularly. According to AO evaluation of the knee and ankle joint movement,83% (35/42 cases) of the cases gained satisfactory functional outcome,14% (6/42 cases) had quite satisfactory results and 2% (1/42 case) had unsatisfactory functional outcome.Conclusion External bracket fixation can obtain outcome of relative length of the tibia and fibula,tube structure reconstruction,smoothness of the articular surface and the parallel and symmetric relation of knees and ankles for complex tibia diaphysis fracture with proxi- mal and distal intra-articular fracture.The arthritis resulting in pain in movement and restriction of func- tion is considered to be the most important factor affecting the joint function.Early functional exercise is important for best recovery of knee and ankle function.

ObjectiveTo investigate the difference of blood pressure variability among patients with lacunar infarction,nonlacunar infarction and normotension.MethodsBlood pressure was measured serially at 1-hour intervals during the first 24 hours after infarction with ambulatory blood pressure monitoring in 31 patients(17 cases with nonlacunar infarction and 14 cases with lacunar infarction).The blood pressure variability index were compared.ResultsBoth 24 h and day systolic blood pressure variability were significantly higher in lacunar infarction patients compared with nonlacunar infarction ones.ConclusionFluctuation of systolic blood pressure may disturb small arteries rather than large or middle arteries.

ObjectiveTo investigate the therapeutic effectiveness of low-power laser on myofascial pain syndrome. Methods73 self-controlled patients with myofascial pain syndrome were irradiated on myofascial trigger points with Nd:YAG laser in wavelength 830nm, power 500mW, 20 minutes per day for 5 times. At pre-and post-treatment,pain intensity and pressure pain of myofascial trigger points were checked. ResultsAfter treatment, score of pain intensity was reduced signficantly from (7.24±2.41) to (2.21±1.22) (P<0.001). The pressure pain of myofascial trigger points were improved . Conclusions Low-power laser can reduce the pain intensity and increase the pressure pain threshold of myoficial trigger points.
