ABSTRACT
Twenty five patients with obstructive sleep apnea hypopnea syndrome (OSAHS) were classified as mild, moderate and severe grade according to apnea hyponea index and lowest oxyhemoglobin saturation.Lower limbs were examined with ultrasonography, blood routine and D-dimer levels were measured in all patients.The results revealed an increased incidence of deep vein thrombosis with the extent of obstructive sleep apnea.There was no deep vein thrombosis in patients with mild-grade OSAHS, while there were 2 in moderate and 3 in severe patients.The blood D-dimer levels were (498 ± 22) pg/L, (659 ±43 ) μg/L, ( 1528 ± 181 ) μg/L in mild, moderate and severe patients, respectively.The hemoglobin levels were (150 ± 8) g/L, ( 183 ± 15) g/L and (261 ± 26) g/L in mild, moderate and severe patients,respectively.There may be some association of obstructive sleep apnea hypopnea syndrome with deep vein thrombosis.
ABSTRACT
Objective To investigate association between human leukocyte antigen DQB1 (HLADQB1 ) gene polymorphisms and bronchial asthma among Mongolian and Han nationalities. Methods Sequence-specific primer polymerase chain reaction (PCR-SSP) was used to detect frequencies of HLA DQB1 genotypes and alleles in 50 cases of Han and 68 Mongolian asthmatic patients, and 50 Han and 54 Mongolian healthy controls, respectively. Difference in gene frequencies between the two nationalities was estimated by odds ratio (OR) and chi-square test. Results Frequency of the HLA-DQB1 0602 allele was significantly higher in Han patients with bronchial asthma than that in healthy Han nationality (OR = 6.163,P ＜0.01 ). Frequency of the HLA-DQB1 0603/0608 allele decreased in Mongolian asthmatic patients, as compared to that in healthy Mongolians ( OR = 0.199, P ＜ 0.05 ). Frequency of the HLA-DQB1 0301/4 allele was significantly higher in Mongolian asthmatic patients as compared to that in healthy Mongolians ( OR =2.074,P ＜0.05). Frequency of the HLA-DQB1 0301/4 allele was significantly higher in Mongolian than that in Han asthmatic patients ( OR = 2.482 ,P =0.05). Frequency of the HLA- DQB1 0602 allele was significantly higher in healthy Mongolians than that in healthy Han nationality ( OR = 3.341, P ＜ 0.05 ), in contrast, frequency of the HLA-DQB1 0402 allele was significantly lower in healthy Mongolians than that in healthy Han nationality ( OR = 0.209, P ＜ 0.05 ). Conclusions The HLA-DQB1 0603/0608 allele is possibly a protective gene and the HLA-DQB1 0301/4 allele a susceptible gene for bronchial asthma in Mongolians, and the HLA-DQB1 0602 allele is possibly a susceptible gene for bronchial asthma in Han nationlity.
ABSTRACT
Objective To explore the clinical outcome of self-designed bilateral external fixator combined with limited internal fixation for the treatment of open fracture of tibial plateau.Methods From February 2001 to September 2005,23 cases of open tibial plateau fractures were treated with bilateral external fixator combined with limited internal fixation.According to Schatzker classification,there were 35 patients with type Ⅴ fracture and 18 patients with type Ⅵ fracture.According to Gustilo classification,there were type Ⅰ in 15 eases,type Ⅱ in 22 cases, type Ⅲ in 16 cases.Results The follow-up period was 5 to 22 months(mean 10 months).All the fractures got unit- ed.According to Merchant grade,18 eases were evaluated as excellent,25 as good,9 as fair.The rate of excellent and good resuhs was 83 %.Conclusion Operation by using bilateral fixator combined with limited internal fixator can make fixation stable and reduce complication.It is an effective method to treat complex fractures of open tibial plateau.
ABSTRACT
<p><b>OBJECTIVE</b>To study the effects of Osteoking in promoting gene expression of core binding factor alpha 1 (cbfalpha 1) in necrotic femoral head of rabbits.</p><p><b>METHODS</b>Rabbit model of femoral head necrosis (FHN) was induced by intravenous injection of lipopolysaccharide (LPS) 10 microg/kg body weight twice with an interval of 24 h and intramuscular injection with methyl prednisone (MPS) 20 mg/kg body weight 3 times. The dynamic changes of cbfalpha 1 gene expression in the femoral head were observed with immunohistochemistry and real-time quantitative PCR.</p><p><b>RESULTS</b>The protein expression of cbfa 1 gene was negative in both model and treatment groups at the 4th week, it turned to weakly positive in the treatment group at the 8th and 12th week but still negative in the model group. The mRNA expression of cbfalpha 1 in the treatment group was 2.87 times that in the model group at the 12th week. There was no significant difference in cbfalpha 1 expression between the normal rabbits with or without Osteoking treatment.</p><p><b>CONCLUSION</b>Osteoking could promote the endogenous cbfalpha 1 expression in the FHN, the effect is better along with the prolonging of the time applied. But it showed no affection on cbfalpha 1 expression in the normal femoral head of rabbits.</p>

<p><b>OBJECTIVE</b>To evaluate the effect of Osteoking ( masculine(1)i) in preventing postoperational deep venous thrombosis (DVT) in patients with intertrochanteric fracture (ITF).</p><p><b>METHODS</b>With prospective and randomized controlled clinical design adopted, 62 patients with ITF after operation were assigned into 2 groups, the tested group and the control group, Osteoking (25 ml every other day) and Sanchi-dansheng tablets (3 tablets thrice a day) were given orally to them respectively for 10 days. Difference of round length of thighs and shanks between two sides were measured on the 10th day and Doppler ultrasonic examination on the fractured leg was carried out.</p><p><b>RESULTS</b>The occurrence rate of DVT in the tested group was 9.4%, which was lower than that in the control group (30.0%, P < 0.05). All the difference of round lengths, either that of the thigh or the shank, was less in the tested group than that in the control group, showing statistical significance (P < 0.05).</p><p><b>CONCLUSION</b>Osteoking has a satisfactory effect in preventing postoperational DVT in patients with ITF.</p>

Objective From the observation of pulmonary function changes in SARS patients during the convalescent period, we aimed to understand if there would be long-term pulmonary function lesions.Methods Pulmonary function tests were performed in 82 SARS patients 3 months after their discharge from hospital (study group) and the abnormal ones were performed pulmonary function tests 6 months after their discharge. The pulmonary function of 28 healthy persons were tesed(control group).Results Pulmonary function tests showed that the mean diffusing capacity of CO(DLCO) was (78.4?17.4)% in study group and (93.8?13.6)% in control group(P35%) in 28 and 11 cases,restrictive defect in 9 and 5 cases.According to the involved areas in chest X-ray during the hospital,the study group were divided into three subgroups:mild,moderate and severe.There was a positive relation between the severity of the disease and the diffusing function lesions 3 months after discharge from hospital.There was no obvious difference in the pulmonary function lesions between the severe patients treated with mechanical ventilation and those not.Conclusion Some of SARS patients have left pulmonary function lesions 3 months and 6 months after their discharge from hospital,which mainly are diffusing capacity abnormality.A few cases have small airway obstruction,residual volume increase and restrictive defect.
ABSTRACT
Objective To explore the feature of electrical physiology and the key aspect of diagnosis in early stage of spinal muscular atrophy in infants.Method The back clinical data of the musle change of electrical physiology within 25 cases were analyzed.Results The children were ill in 1 year old,with the symptom that four limbs present symmetry and paralysing slowly,low limbs being more serious than upper limbs,the close and the distant of the four limbs.The levels of creatine kinase(CK) and lactate dehydrogenase(LDH) in serum were normal and the case unconcentrated was not seen rarely.The show of electromyogram(EMG) was that three limbs presenting wide-range losing nerve electric potential in peace state,when straingently the deadline was long and the motor unit potential(MUP) was high,when strain highly the eletric potential was decreased;the speed of nerve conduction was common.Muscle inspection was typical nervine myatrophy.Conclusion The clinical feature,the changes of muscle electrical physiology and the muscle inspection are valuable for diagnosis so as to afford reliable evidence for further gene diagnosis.J Appl Clin Pediatr,2006,21(3):167
