Objective To explore the relationship between the sleep quality and diabetic autonomic neuropathy of elder patients with type 2 diabetes mellitus.Methods A total of 90 elder patients with diabetes in Beijing Hospital was enrolled in this study.Questionnaires of Pittsburgh Sleep Quality Index (PSQI) were completed to evaluate the quality of sleep and Holter was applied to evaluate heart rate variability (HRV).Other related clinical data such as,catecholamine [epinephrine (E);norepinephrine (NE);dopamine (DA)] and diabetes complications were also collected after admission to the hospital.Patients were divided into three groups:the poor-sleeper group,the common-sleeper group and the goodsleeper group according to PSQI score.HRV and the level of catecholamine were compared among three groups.Results The level of HRV including meanNN [(743 ±58) ms vs(824 ±99)ms and (837 ± 104) ms],ASDNN [(30 ± 10) ms vs (39 ± 14) ms and (41 ± 14) ms],very low frequency(VLF) [(15.33 ± 6.10) ms2 vs (22.11 ± 7.94) ms2 and (22.66 ± 7.87) ms2],low frequency (LF) [(8.30 ± 3.95) ms2 vs (12.58±6.11)ms2 and(12.81 ±6.96)ms2] and LF/high frequency(HF) [(1.23 ±0.32) vs (1.56 ± 0.46) and (1.47 ± 0.42)] in the poor-sleeper group were lower than in both the common-sleeper group and good-sleeper group (all P ＜ 0.05).The level of catecholamine in poor-sleeper group [E:(108.91 ± 4.19) ng/L;NE:(1458.0 ± 50.35) ng/L] were lower than both the common-sleeper group [E:(120.23 ± 4.37) ng/L;NE:(1901.09 ± 131.36)ng/L] and the good-sleeper group [E:(118.23 ± 19.9) ng/L;NE:(1771.87 ± 116.73) ng/L] (all P ＜ O.05),suggesting a dysfunction in autonomic nervous system in subject in the poor-sleeper group.Conclusion Sleep quality is associated with the severity of diabetic autonomic neuropathy and might be one of clinical features for diabetic autonomic neuropathy.

Objective To investigate the clinical features, diagnostic criteria and treatment of primary pulmonary lymphoma (PPL). Methods 11 patients with PPL, the diagnosis of which was made with pathological study of biopsy specimen, admitted from 1997 to 2006 to General Hospital of PLA, were retrospectively analyzed. The data collected for the present study, combined with some references, were reviewed concerning the clinical characteristics, X-ray features, pathologic features, bronchoscopic observations, diagnostic criteria as well as treatment. Results PPL was a rare disease, and was hard to have a definite diagnosis for lack of specific clinical symptoms. The most common clinical symptoms of PPL were cough, chest distress, fever etc. X-ray features included solitary or multiple nodules, ground-glass opacity, filamentous shadow and consolidation shadow. Such signs could be seen at the same time, commonly accompanied with air bronchogram. No distinct changes could be found in bronchofibroscopy. Final diagnosis of PPL could be made when a CT guided biopsy was done, followed by pathological examination with immunohistological study, or study of the tumor after surgery. Surgical operation and chemotherapy were the major effective therapeutic approach for the treatment of PPL. Prognosis was favorable in patients with low degree of malignancy of the tumor. Conclusion The clinical characteristics and X-ray image of PPL are not specific. Misdiagnosis occurs commonly. The final diagnosis of PPL depends on the pathologic examination of the PPL tissue. Appropriate CT guided biopsy is necessary for an early diagnosis. Surgery as well as ancillary chemotherapy after operation could get satisfactory results.

Objective To investigate the changes in concentration of plasma von Willebrand factor (vWF) and the effects of heme oxygenase-1 (HO-1) in rabbits with endotoxin (ET)-induced acute lung injury (ALI). Methods Twenty four male New-Zealand rabbits were randomly assigned to three groups: control group, ET group and hemin-treatment group. Saline was iv. injected into the animals of control group; in animals of ET-treatment group ALI model was reproduced with endotoxin iv. injection (700 ?g/kg); animals of hemin-treatment group received intraperitoneal injection of heme for 2 days before ET challenge (40?mol/kg, 2 times per day). Arterial blood gas assay was performed and the plasma vWF concentration was determined with ELSIA at 0h (pre-experiment), 0.5, 1, 2 and 4h time points for the animals in all three groups. When the rabbits were sacrificed, the dry/wet weight ratio of lung and HO-1 (mean density) were determined and the pathological changes in lung tissue were examined. Results Compared with control group, the partial pressure of oxygen (PaO2) and oxygenation index (PaO2/FiO2) declined, meeting the diagnostic criteria of ALI, and plasma vWF concentrations increased obviously (P

Objective To evaluate the value of transvaginal ultrasound in the diagnosis of tubal pregnancy.Methods The retrospective analysis was made according to transvaginal ultrasound inspection on 77 patients and their sonographic appearance and ultrasonic diagnosis of tubal pregnancy proved by surgery and pathology.Results The two-dimensional sonogram mainly showed the adnexal masses and the liquid area opaca in the pelvic cavity.The masses were divided into three types:germ heart-beat type,gestational sac type,and uneven mixed mass type.According to distinctive two-dimensional sonographic appearance,the accuracy rates of transvaginal ultrasound in the diagnosis of rupture,nonrupture,and abortion tubal pregnancy were 87.23%,100%,and 34.62%,respectively.In combination with pelvic mass,indirect sign of effusion,and patient history,the accuracy rates of ultrasonic diagnosis in the above clinical classifications were 95.74%,100%,and 84.61%,respectively.The accuracy rate of the total ultrasonic diagnosis was 92.21%.Conclusions Transvaginal ultrasound has higher accuracy in the diagnosis of rupture and nonrupture tubal pregnancy,but it lacks distinctive sonographic appearance in the diagnosis of the majority of abortion tubal pregnancy,which is the main reason for affecting the accuracy of ultrasonic diagnosis of tubal pregnancy.

Objective To evaluate the characteristics of the haemodynamics of the hysteromyoma and its diagnosis value. Methods To apply the transvaginal color doppler ultrasound to detect the blood flow parameters of the uterine artery and the muscular tumor’s peripheral and inner area from 68 patients with hysteromyoma, compared with the blood flow parameters of the uterine artery from 50 normal women so as to analyze their difference. Results (1) In the hysteromyoma group, the maximum blood flow velocity during the systolic phase (SP) and the minimum blood flow velocity during the end-diastolic phase (ED) of uterine artery are significantly higher than those in the normal group(P

Endometrial blood flow is directly related to endometrial receptivity thereby affecting in vitro fertilization and embryo transfer (IVF-ET) outcomes. In recent years a growing number of studies have shown that traditional Chinese medicine (TCM) can play a role to improve endometrial blood flow and embryo transfer. Studies have confirmed that formulas based on reinforcing kidney and activating blood can promote the formation of uterine endometrial blood vessels by adjusting expressions of a variety of vessel growth factors, and regulating nitric oxide level for inhibition of vascular smooth muscle contraction of the uterus. Treatments based on differentiation of syndromes are key to the theory of TCM. Differentiation of syndromes should be combined with biomedical disease diagnosis. It is also necessary to further clarify other endometrial blood flow disorders using TCM diagnostic methods. In these cases, drugs for reinforcing kidney and activating blood are relevant, but other medicines for smoothing liver qi and nourishing blood, as well as tonifying the spleen and generating blood may also be effective. Future clinical studies should focus on the observation of different types of TCM syndromes and the research on compatibility ratio and dose-dependent relationship of Chinese medicines. Acupuncture has been used during IVF-ET for more than 10 years. Electro-acupuncture can control the expansion of the uterine arteries by inhibiting the sympathetic nerves. However, acupuncture has not been proved to regulate endometrial arteries. To sum up, TCM can be applied to improve endometrial blood flow so as to increase birth rates in IVF-ET. The combination of Chinese and Western medicines and acupuncture application will increase their combined effect, thereby obtaining greater clinical benefits.

Objective To study the influence of dihydromyricetin on the oxidation and non-enzymatic glycosylation in impaired glucose tolerance rats.Methods Animal model of impaired glucose tolerance rat was built by intragastrical(i.g.) injection of D-galactose generally.After 8 weeks intragastrical(i.g.) injection of dihydromyricetin(experimental group) and metformin (positive control),the levels of fasting blood glucose and tow-hour postprandial blood glucose,the insulin level and its resistance index,the levels of glycosylated hemoglobin (GHb) and advanced glycation end-products(AGEs) were detected,and the activities of superoxide dismutase(SOD) and glutathione peroxidase (GSH-Px),the content of malondiadehyde(MDA) were determined respectively.Results Compared with model group,dihydromyricetin decreased the level of two-hour postprandial blood glucose (P0.05).Conclusion Dihydromyricetin can significantly improve the state of impaired glucose tolerance rats; the mechanism may be related to its effect of improving the antioxidant activity of GSH-Px,inhibiting non-enzymatic glycation,lowering body oxidative stress and insulin resistance and promoting the use of blood glucose in peripheral organizations.
