BACKGROUND: The use of bone graft materials can promote bone fusion and enhance the stability of the spine during the spinal fusion. OBJECTIVE: To investigate the effect of autologous bone marrow mesenchymal stem cel s with hydroxyapatite/ tricalcium phosphate in the spinal fusion. METHODS: A retrospective analysis of clinical data of 64 patients with spinal fusion was carried out, and these patients were divided into two groups (n=32 per group): control group undergoing autogenous iliac bone grafting and observation group undergoing autologous bone marrow mesenchymal stem cel s combined with hydroxyapatite/tricalcium phosphate. Al patients were fol owed up for 12 months, and their recovery conditions about low back pain, spinal fusion and vertebral reset were assessed. RESULTS AND CONCLUSION: The low-back outcome scale scores and excel ent rate, Lenke grading and Cobb angle had insignificant differences between the two groups after treatment (P > 0.05). No infection, inflammation and skin irritation occurred in the two groups. The coagulation function, renal function and inflammatory factor levels were at normal levels in al the patients, and there was no difference between the two groups (P > 0.05). These findings indicate that autologous bone marrow mesenchymal stem cel s combined with hydroxyapatite/tricalcium phosphate can achieve clinical outcomes equivalent to the autologous iliac bone grafting.

Objective To evaluate the value of peripheral blood neutrophil CD_(64) level for early diagnosis of neonatal septicemia.Methods Thirty-six cases of neonatal septicemia were recruited into the study according to diagnostic criteria for neonatal septicemia:white blood cell count,C-reactive protein(CRP),platelet count,micro-erythrocyte sedimentatio rate(mESR) and blood culture;26 cases of hospitalized neonates with non-infectious diseases were enrolled as controls.The level of peripheral blood neutrophil CD_(64) was measured by flow cytometry.Results The level of peripheral blood neutrophil CD_(64) in septicemia patients were(60.37?22.70)mean fluorescence intensity(MFI),which were significantly higher than that of control group(23.14?5.10)MFI(P

Objective To evaluate engraftment status of patients after allogeneic hematopoietic stem cell transplantation(Allo-HSCT) and prompt relapse of disease based on DNA polymorphism analysis technique.Methods Sixty-six cases were detected by DNA polymorphism analysis technique and 25 cases were monitored and analyzed dynamically during this period.Results After Allo-HSCT,48 patients obtained type of donors,but 13 patients did not; 5 patients showed mixed chimerism.Two cases of type of donors converted into mixed chimerism and 4 cases of mixed chimerism converted into type of donors after some time. The others' engraftment status did not change.Conclusion DNA polymorphism analysis technique can detect engraftment status of patients exactly, rapidly, which provides effective evidences of constitution for more clinical therapy projects.

OBJECTIVECongenital esophageal stenosis owing to tracheobronchial remnants (TBR) is a rare condition. This study was conducted to understand the clinical features of TBR.
METHODThe data of the four cases with TBR admitted to our hospital and 76 patients identified from the literature were reviewed. The clinical manifestation, X-ray, endoscopy, biopsy and treatment were studied retrospectively.
RESULTOf the total of 80 cases, 45 were male, 33 were female, and for 2 cases the gender was unknown. Symptoms of dysphagia and regurgitation developed at the age of 1-day to 12-month. Definitive treatment was carried out at the age of 1-month to 16-year. Twenty-seven patients had associated anomalies with esophageal atresia being the most prevalent. X-ray esophagography showed segmental stenosis at the distal third of the esophagus in all patients except three. An abrupt narrow segment at the lower esophagus with marked proximal dilatation was found in 32 cases. Esophagography of 12 cases showed distal esophageal stenosis with tapered narrowing. Esophagography of 20 cases showed flask-shaped shadow of distal esophageal stenosis and one patient showed linear projection of barium at the level of stenosis. Endoscopy found almost complete obstruction of the lower esophageal lumen without signs of the esophagitis or reflux. Esophagoscopic dilatation of the stenosis was attempted in 24 cases, but was ineffective, and 3 patients suffered esophageal perforation. Seventy-nine patients underwent resection of the stenotic segment. Histologic examination of the resected specimen showed cartilage, mucus glands, resembling bronchal tissue. Post-operative complication included anastomotic stenosis, anastomotic leakage, hiatal hernia, and gastroesophageal reflux.
CONCLUSIONTBR should be suspected in patients who present with a typical history of dysphagia after ingestion of solid food. Esophagography and esophagoscopy are the essential means for diagnosis. TBR should be different from achalasia and should be diagnosed by biopsy. Operation is the only choice of treatment.

Objective To investigate the relationship between pure -tone audiometry (PTA ) ,speech dis‐crimination abilities in quiet or in noise and the international outcome inventory for hearing aids (IOI-HA) in pres‐bycusis patients .Methods Twenty presbycusis subjects were tested in this study .Pure-tone audiometry (PTA) and speech discrimination threshold were obtained before being fitted with hearing aids .They weared hearig aids more than six months ,and pure-tone audiometry ,speech discrimination scores in quite(the level = 65 dB SPL) and in noise(signal to noise ratio = 10 dB) were carried out in sound field .A stepwise forward multiple-regression analysis was performed to investigate the impact of PTA and speech discrimination scores to IOI-HA .Results The PTAs before or after hearing aid fittings showed a negative association with IOI-HA ,while speech discrimination scores in quiet or in noise before or after hearing aid fittings showed a positive association with IOI-HA .Speech discrimination threshold in noise was identified as a single predictor of IOI-HA(P<0 .001) .Conclusion The relation between speech discrimination scores in noise and IOI-HA suggests that a poor score might limit the hearing aids outcome .The speech discrimination scores in noise help the clinicians predict the outcomes of hearing aid in real‐ities .

Objective To investigate the spectrum,diagnosis,time of therapy and management of the congeni-tal heart disease(CHD)in patients with Down′s syndrome(DS).Methods A retrospective report was undertaken of 96 cases in children with DS accompanied by CHD in Department of Pediatric Cardiology,Beijing Anzhen Hospital Af-filiated to Capital Medical University.Data were collected and analyzed about their clinical characteristics,and types of cardiovascular abnormalities,and the important laboratory examinations such as echocardiography and catheterization as well as the procedures of diagnosis and treatments were summarized.Then the interventions,complications and prognosis of different patients were estimated.Results (1)Single congenital heart disease was found in 33 cases (34.38%),a-mong which ventricular septal defect was the most common (14 cases,14.58%),followed by atrioventricular septal de-fect and atrial septal defect (equally,7 cases,7.29%).Multi -cardiovascular abnormalities were discovered in 63 ca-ses,and patent ductus arteriosus turned out to be the most common (42 cases,66.67%).(2)Cat-heterization was car-ried out in 18 cases of serious pulmonary arterial hypertension,and 8 cases were proved resistant pulmonary arterial hy-pertension without operation opportunity.The other 8 cases were estimated as high pulmonary arterial hypertension and medical therapy was suggested before reassessment to reduce surgical risks.(3)Operations were undertaken in 61 ca-ses,among which percutaneous interventional occlusion was performed in 7 cases and surgical interventions were per-formed in 54 patients,in which perioperation complications and death were found in 5 cases and 4 cases,respectively. Conclusions Operation interventions are practicable and most cases recovered well with systematic examinations and assessment in patients with DS and cardiovascular malformations.Early diagnosis and timely interventions are highly suggested.Also close attentions should be paid to follow -up and re -estimation after medical therapy.
