BACKGROUND: Studies have found that Sambucus sibirica Nakai can promote osteoblast division, proliferation, and secretion of alkaline phosphatase to accelerate bone matrix calcification, promote new bone formation, and promote the absorption of necrotic bone. OBJECTIVE: To observe the effects of two extracts of Xinjiang Sambucus sibirica Nakai bark in promoting fracture healing in rats. METHODS: A total of 108 male Sprague-Dawley rats, 3 months old, were randomly divided into sham-operated group, model group, Zhong Hua Die Da Wan group (0.54 g/kg, negative control group), high-, middle- and low-dose ethanol extract groups (0.314, 0.157, 0.078 g/kg), high-, middle, and low-dose water extract groups (0.340, 0.170, 0.085 g/kg). Except for the sham-operated group, the middle segment of the femoral shaft was cut off to make a model of open femoral fracture. In the sham-operated group, only the femoral shaft was exposed and no osteotomy was performed. Intragastric administration began at 1 day after modeling and continued for 6 weeks (1 time/day). At 2, 4, 6 weeks after modeling, the effects of two extracts of Sambucus sibirica Nakai bark on serum-related biochemical indicators, X-ray imaging, biomechanical indicators and hematoxylin-eosin staining were observed. RESULTS AND CONCLUSION: (1) Serum biochemical indicators: The serum calcium level of the high-dose ethanol extract group in each phase was lower than that of the sham-operated group and the model group, indicating that a faster osteogenesis in the high-dose ethanol extract group, followed by middle-dose ethanol extract group, low-dose ethanol extract group, and high-dose water extract group. The serum phosphorus level of ethanol extract groups was higher than that of sham-operated group, model group, and Zhong Hua Die Da Wan group; the serum alkaline phosphatase level of high-dose ethanol extract group at each stage was significantly higher than the other groups, indicating that a stronger osteoblast activity in the high-dose ethanol extract group, followed by the high-dose water extract group. (2) X-ray film: Fracture healing was significant in the high-dose ethanol extract group, fair in the Zhong Hua Die Da Wan group, high-dose water extract, middle-dose water extract group, middle-dose ethanol extract group, and poor in the low-dose ethanol extract group and low-dose water extract group. (3) Three-point bending test: At 6 weeks, the maximum load and maximum deflection of the femurs of the two extract groups were higher than those in the model group. The maximum load and maximum deflection of the femurs increased significantly in the high-dose ethanol extract group followed by the high-dose water extract group, middle-dose water extract group and middle-dose ethanol extract group. (4) Hematoxylin-eosin staining: Fibrous epiphysis gradually formed in the fracture area, and the bone marrow cavity was communicated. Bone healing was better in the high-dose ethanol extract and high-dose water extract groups than in the other groups. To conclude, these two extracts of Xinjiang Sambucus sibirica Nakai bark are capable of improving fracture healing. Moreover, different extraction methods and dosages of Sambucus sibirica Nakai bark demonstrate various effects on fracture healing. Compared with water extracts, ethanol extracts are better to promote fracture healing, and high-dose extracts have better effects than middle- and low-dose extracts.

Objective To observe the abnormal Minnesota code (MC) distribution and interrelated characteristic on electrocardiograms (ECGs) of the adult Kazakh population.Methods Resting ECGs and blood press of randomly sampled 30 000 adult Kazakh people in three Northern regions of Xinjiang were continuously examined and analyzed,using Minnesota code recommended by WHO as the classification of ECG.Results The overall rate of abnormal ECG findings was 248.60‰,and the main abnormality in males was 146.83‰,compared to 157.71‰ in females.The prevalence rates of abnormal ST-T changes,the total arrhythmia and atrial fibrillation (AF) were 100.03‰,71.17‰ and 2.83‰ respectively.There were statistically significant differences among the main abnormities from the three regions.Conclusion The ECGs abnormalities of adult Kazakh people were high.There was significant relation found between the main abnormalities and hypertension.The prevalence of AF was different from the domestically reported literature that calls for further study.

OBJECTIVETo establish the rat model of acute pulmonary embolism, and study the changes of vascular active substances in pulmonary embolism rats, and investigate the interventive effect of anticoagulant drugs on vascular active substances.

METHODSOne hundred and twenty-eight rats were randomly divided into four groups: control group, model group, low-molecular-weight heparin and warfarin treated group and rivaroxaban-treated group (n = 32 in each group). The method of autologous thrombosis was used to establish the animal model of acute pulmonary embolism. The animals were treated with saline or different anticoagulant drugs. The physiological and biochemical parameters were detected at different time points after embolization. The rats were killed after embolism of 24 h, 3 d, 5 d or 1 week respectively and the pathologic samples of lung tissues were collected to analyze the pulmonary pathological changes in different groups.

RESULTSRats in embolization group after blood clots injection showed shortness of breath, oral cyanosis; quicken heart rates and other symptoms. All embolization groups had pulmonary hypertension, the levels of type B natriuretic peptide (BNP) were increased significantly. The ratio of endothelin-1 (ET-1)/NO and thromboxane (TXB2) and prostacyclin (6-k-PGFla) were abnormal. After treated with effective anticoagulant drugs, the levels of BNP, ET-1, NO, TXB2 and 6-k-PGF1a were tended to the normal levels in the control group. The pulmonary hypertensions were gradually decreased. The efficacy of rivaroxaban on pulmonary embolism was the same as that of the low molecular weight heparin or warfarin.

CONCLUSIONAnticoagulation therapy can effectively improve endothelial function after pulmonary embolism, reduce pulmonary hypertension, and revise the increased BNP levels to normal levels. The efficacy of rivaroxaban is not inferior to that of low molecular weight heparin and warfarin.

OBJECTIVETo study the temporal trend and spatial distribution of premature mortality burden due to chronic obstructive pulmonary disease (COPD) in terms of years of life lost (YLL) in an urban region of Kunming for the years 1998-2003.

METHODSPan Long district was selected as the study region. YLL was used to measure premature mortality burden due to COPD. The tate of YLL per 1000 residents was calculated without age-weighting but with 3% discounting rate and broken down by year. Geographic information system (GIS) technique was used to display the spatial distribution of premature mortality burden due to COPD during the six years of study.

RESULTSDuring the years from 1998 to 2003, the premature mortality burden due to COPD decreased by years while males seemed to have a higher YLL rate of COPD than females. Central areas remained to have higher YLL/1000 population values of COPD for the six years, whereas remote areas tended to have a decreasing trend of YLL/1000 population values of COPD in the same period.

CONCLUSIONCentral areas of the city should be emphasized in further control of COPD in the urban region of Kunming.

OBJECTIVETo study whether hematologic malignancy patients with anemia have a lower erythropoietin (EPO) response.

METHODSSerum EPO levels were detected by ELISA in patients with hematologic malignancies and with iron deficiency anemia (IDA). Eighty patients with hematologic malignancies, including 13 multiple myeloma (MM), 7 chronic lymphocytic leukemia (CLL) and 60 non-Hodgkin's lymphoma (NHL) were studied. Thirty of them had anemia(21 NHL,6 MM and 3 CLL). Twenty patients with IDA were studied as the control.

RESULTSHematologic malignancy patients with anemia had higher EPO levels [(97.8 +/- 183.9) IU/L] than those with normal Hb values [(27.8 +/- 85.4) IU/L; P <0.01]. In patients with IDA, serum EPO response was inversely correlated with Hb level (r= -0.5, P <0.05) , but no such inverse correlation was found in the hematologic malignancy patients with anemia (r = -0.14). After corrected for Hb level, the serum EPO levels were significantly lower in anemic patients with hematologic malignancies than in IDA patients (P = 0.032) , indicating a decreased EPO response in the former group.

CONCLUSIONAnemia associated with hematologic malignancy might result from an inappropriately low EPO response. EPO treatment for these patients may be beneficial.

OBJECTIVETo evaluate the methods of repairing urethral fistula resulting from hypospadias operation.

METHODSWe analyzed the clinical data of 46 cases of surgical repair of urethral fistula resulting from hypospadias operation. The patients ranged in age from 3 to 26 (mean 11.7) years. There were 52 fistulas in all, with the diameters of less than 5 mm, of which 25 were in the midshaft of the penis, 12 in the penoscrotum, and 9 in the scrotum. Of the 46 cases, 20 were repaired by continuous knock suture and 26 by tunica vaginalis of testis and spermatic fascia.

RESULTSThe one-stage success rate of continuous knock suture repair was 55% (11/20) and that of the combined use of continuous knock suture with tunica vaginalis of testis and spermatic fascia repair was 84.6% (22/26).

CONCLUSIONBased on continuous knock suture, the additional use of tunica vaginalis of testis and spermatic fascia yields a high success rate in repairing urethral fistula resulting from hypospadias operation.
