Objective The questionaires of the ONFH aegers who were hospitalized in Kanggu hospital,during 2005-2008 ,were collect-ed to evaluate the therapeutic effects of acupotomy by proper statistical methods. Methods Four indexes according to the criteria of Therapeutic effect of adult ONFH recovery and reconstruction (ZHAO Dewei, 1996) were measured to evaluate the effect of the treatment. Results Monofac-torial analysis showed that the treatrnent was effective,but some phenomena could not be correctly explined in specialized field. This problem was re-solved appropriately by structural equation model(SEM). Conclusion By the method of SEM, the confounding factors could be better controlled and the evaluation was more reliable.

Objective To explore the correlation between obstructive sleep apnea hypoventilation syndrome (OSAHS)and glucose metabolism disorders in patients without diabetes mellitus.Methods A total of 88 patients with OSAHS but without diabetes mellitus from 2009 to 2011 in our hospital were selected and the pulse oximeter were used to measure the oxygen saturation.Patients were divided into 2 groups:the mild OSAHS group (n=46) and the severe OSAHS group (n=42).The age-and body mass index (BMI) matched control patients without OSAHS (control group,n =48) were randomly selected.The medical history,age,body height and BMI were recorded.The levels of fasting blood glucose,glycated hemoglobin (HbA1c),cholesterol,triglyceride and low density lipoprotein cholesterol were determined.Results There were significant differences in the numbers of respiratory disorders,respiratory disturbance index,average length of apnea,the longest apnea time,low-oxygen frequency,oxygen index,the time of oxygen saturation (SaO2) below 90％,minimum SaO2 and mean SaO2 between the OSAHS group and the control group (F=2.71,2.89,1.94,2.30,2.93,2.27,3.66,3.06,1.82,respectively,all P＜0.05).There were differences in the levels of fasting blood glucose,postprandial blood glucose,HbA1c,cholesterol,triglycerideand low density lipoprotein cholesterol between the three groups(F=1.81,1.85,2.16,1.77,2.24,2.19,respectively,all P＜0.05).Conclusions The severe degree of OSAHS has the correlation with the levels of glycated hemoglobin and blood glucose,which can provide a basis to observe the duration of diabetes mellitus and to predict the risk of cardiovascular diseases.

Objective To explore the inhibition effect of interleukin-10(IL-10)on pneumonic anaphylacticitis in mice with asthma and its effects on the level of serum IgE.Methods Thirty BALB/c male mice whose weight were(20?2)g were randomly divided into 3 groups:normal group(n=10),asthma model group(n=10)and IL-10 treatment group(n=10).Asthma model group and IL-10 group were sensitized with 1 g?L-1 ovalbumin,then asthma model was made with inhallating 10 g?L-1 VOA 20 mL.The normal group was not administered anything as a negative group.Before inhallating with 10 g?L-1 VOA,asthma model group was administered inhalation with 9 g?L-1 saline 0.1 mL,and IL-10 treatment group was administered inhalation with 0.1 mL IL-10 whose concentration was 0.2 ?g?L-1.The level of IgE was measured by ELISA reagent box,eviscerated lungs after collecting blood and then made them into pathological slices.Results There was an obvious distinction in the mice pathological change of lungs and bronchus between asthma model group and other groups,but no significant difference between IL-10 treatment group and normal group.There was no obvious infiltration of inflammatory cells in the airways of IL-10 treatment group and normal group.However,there were a great number of inflammatory cells in the interstitial and peribronchovascular regions of asthma model group.The levels of serum IgE were(5.219?0.427)?g?L-1,(6.633?0.145)?g?L-1 and(5.503?0.566)?g?L-1 in normal group,asthma model group and IL-10 treatment group,respectively.The level of serum IgE in asthma model group increased obviously compared with normal group and IL-10 treatment group,with significant differences(Pa0.05).Conclusions Inhalation of IL-10 can optimally control the pneumonic anaphylacticitis,improve the situation of airway inflammation in mice asthmatic model and reduce the IgE serum level.

Objective Wegener's granulomatosis is a rare multisystem vasculitis of unknown aetiology. The clinical features of the disease,the treatment and long-term follow-up is observed in this study.Methods Eleven WG patients were from Rheumatology Department of Guangdong Province People's Hospital between 1999—2005.Data were obtained retrospectively.The patients' clinical manifestation and laboratory results were studied.Results All patients had upper and lower respiratory tracts involvement.The upper respiratory tract(nose,sinus,throat,trachea,and middle ear)-(E)lung(L),and kidneys(K)were the most commonly in- volved organs.The majority of patient received i.v.puls methylprednisolone 0.5 g/d?3 d,followed by oral pred- nisone 1 mg.kg~(-1).d~(-1)and i.v.pulses of cyclophosphamide 750 mg/m~2.The long-term outcome was good. Conclusion Wegner's granulomatosis is a systemic vasculitis occurring in patients with histopathologic mani- festation of necrotizing vasculitis with granuloma formation.Corticosteroid and immunosuppressive treatment may achieve good outcome.

Objective To study the relationship between sperm activity and the level of L-carnitine in seminal plasma of patients with idiopathic asthenospermia by HPLC.Methods Experimental group:idiopathic asthenospermia 50 cases,and the control group:male with pregnancy history 10 cases.The semen parameters (volume,sperm density,viability,motility),and L-carnitine level in seminal plasma were detected with high performance liquid chromatography method.Results There were significant difference between A and B group about sperm density and the percentage of progressive motile spermatozoa,and the level of L-carnitine(P＜0.01).Conclusions The decrease of L-carnitine level in patients with idiopathic asthenospermia,is closely related to the low sperm motility,which shows that L-carnitine can be used to treat idiopathic asthenospermia effectively.

OBJECTIVETo study the consistency between DR and high-kV chest radiographs in diagnosis of pneumoconiosis and to explore the feasibility of DR chest radiograph in the diagnosis of pneumoconiosis.

METHODSTwenty five coal miners were examined with DR and high-kV chest radiographs at the same time. Image post-processing parameters (density, contrast, etc.) were set to ensure the quality of DR chest radiograph in Philips Essenta DR machine. In order to avoid the repetitive numbers, 50 chest radiographs were numbered at random. Pneumoconiosis diagnosis was conducted by six independent certified occupational physicians of pneumoconiosis by blind method. The consistency between 2 kinds of chest films was assessed.

RESULTSAll chest radiographs (25 cases, 50 chest films) were excellent. The diagnosis results of six readers on the 15 pairs of DR and high-kV chest radiographies were summarized. For high-kV chest radiographs, the consistency of pneumoconiosis classification for 12 pairs of readers was more than 68%, the consistency of total density for 11 pairs of readers was more than 68%. For DR chest radiographs, the consistency of pneumoconiosis classification for 13 pairs of readers was more than 60%, the consistency of total density for 14 pairs of readers was more than 60%. The consistency of pneumoconiosis classification between two chest radiographs was 72% (value: 0.69, 95% CI: 0.46-0.92), the consistency of total density between two chest radiographs was 80% (value: 0.78, 95% CI: 0.61-0.95).

CONCLUSIONWhen the chest radiograph quality was good and the difference of reading films was low, there was a good consistency of pneumoconiosis diagnosis between DR chest radiographs and high-kV chest radiographs.

Objective To investigate the expression of endothelin-1 (ET-1 ), nitrogen monoxidium (NO), vascular endothelial growth factor (VEGF) and brain tissue VEGF induced by chronic intermittent hypoxia (CIH) in aged rats. Methods The CIH model of aged rat was established by using intermittent hypoxia. The levels of ET-1, NO and VEGF in the plasma were detected at 3, 6 and 9 weeks after experiment in each group. The expression of VEGF in brain tissues and the pathological changes of the vessels of the cerebra and the ratio between the thickness of vessel wall and external diameter (WT%) were observed. Results In CIH group, the ET-1 and VEGF levels increased, however NO level decreased. The levels of ET-1 and VEGF were higher at 3 weeks in CIH group than in UC group (t=2.47 and 2.38, both P<0.05), however NO level was lower in CIH group than in UC group (t=2.39, P<0.05). VEGF levels increased significantly at 9 weeks in CIH as compared with UC group [(171.1±13.5) pg/ml vs. (109.8±8.6) pg/ml, t = 3.46, P< 0.01]. The levels of VEGF in CIH group increased remarkably at 9 weeks as compared with 3 weeks [(129.3±12.3) pg/ml, t=2.38, P<0.053. VEGF levels in CIH group showed positive correlation with the time of intermittent hypoxia. The changes of cerebral vessels in UC group were not found, while the aged rats in CIH group showed cerebral neuron cells swelling and blood vessel hyperplasia. The WT% of cerebral small artery was more apparent in CIH group than in UC group at 3 weeks (t=2.34,P<0.05). The expression of VEGF in cerebra was higher in CIH group than in UC group in the three stages (r=2.37, P<0.05). There was an aggravated tendency in the change of the expression of brain tissue VEGF and WT% over time. The change was more apparent at 9 weeks than at 3 weeks (t=2.32 and 2.35, both P<0.05). Conclusions CIH can induce an increase in the expression of ET-1 and VEGF, a decrease in the expression of NO in aged rats. The over expression of VEGF and the disbalance of ET-1 and NO levels can cause brain cellular swelling, arteriola vessel wall thickening,lumens stenosis.
