OBJECTIVE:To observe the efficacy and safety of vitamin B12 combined with mouse nerve growth factor in the treatment of neurogenic tinnitus. METHODS:270 patients with neurogenic tinnitus were randomly divided into control group 1, control group 2 and observation group. Control group 1 was treated with Vitamin B12 injection 25 μg by intramuscular injection, once a day;control group 2 was treated with mouse nerve growth factor 18 μg adding into 2 ml water for injection for dissolution, once a day;observation group was treated with Vitamin B12 injection 25 μg(the usage was the same as control group 1)+mouse nerve growth factor 18 μg(the usage was the same as control group 2). 6 d was a treatment course,and it lasted 2 courses. Clinical efficacy,and sleep SPIEGEL score and incidence of adverse reactions before and after treatment in 3 groups were observed. RE-SULTS:Total effective rate in observation group was significantly higher than control group 1 and control group 2,the difference was statistically significant (P<0.05);however,there was no significant difference between control group 1 and control group 2 (P>0.05). After treatment,sleep SPIEGEL score in 3 groups was significantly higher than before,and observation group was high-er than control group 1 and control group 2,the difference was statistically significant(P<0.05);however,there was no signifi-cant difference between control group 1 and control group 2(P>0.05). There were no obvious adverse reactions during treatment. CONCLUSIONS:Vitamin B12 combined with mouse nerve growth factor has better efficacy than only vitamin B12 or mouse nerve growth factor in the treatment of neurogenic tinnitus,with good safety.

ObjectiveTo explore the relationship between the changes of the blood platelet counts (BPC) in children with cerebral palsy (CP) and pather mechanism of CP in traditional Chinese medicine.MethodsBPCs of CP children and healthy children were analyzed with statistical method.ResultsThe BPC of CP children was higher than that of the healthy children ( P<0.05).ConclusionThe BPC of CP children is higher than that of the healthy children, and this is consistent with the theory of traditional Chinese medicine about pathogenic mechanism of CP that CP is related to blood stasis.

Objective To explore the significance of blood lactic acid level and lactic acid clearance in evaluating the prognosis of septic shock.Methods The blood lactic acid concentration of 64 patients with septic shock EICU ICU admission 1h inside,6,12,24 and 48h was recorded,and the lactic acid clearance was calculated 12 hours after treatment,and according to lactic acid clearance of outcome,64 patients were divided into two groups,live group and death group;Then compared blood lactic acid level and lactic acid clearance between the two groups.Results The blood lactic acid concentration of live group and death group when enter the ICU was (7.2 ±5.4)mmol/L,(9.2 ±5.6)mmol/L respectivly,and was higher than normal,and of live group after 6h began to fall,and it reached normal level after 24h [ (2.2 ± 1.3 ) mmol/L ],but of death group after 48 h [ ( 8.0 ± 3.8 ) mmol/L ] was still significantly higher than normal,until death.There was significant difference between the two groups (t =3.7816,3.8257,7.5263,4.5875,5.8765,all P ＜ 0.05 ).The lactic acid clearance of death group after 12 hours was (5.83 ±3.92)mmol/L,and significantly lower than that of live group[ ( 14.32 ±2.68) mmol/L] (t =6.2565,P ＜0.05).Conclusion Blood lactic acid concentration was positively related to the prognosis of patients with septic shock,and dynamic response of disease progression by detecting lactic acid clearance rate could be early,sensitive,quantitative indicators to determine the severity of critical illness.

Objective To investigate freshmen's prevalence of depression disorder and to analyse the in-fluential factors on depression in military colleges. Methods Depression, self-consciousness, coping style, per-sonality feature, birth background and other factors were investigated by MMPI and related questionnaires in 683 freshmen of military colleges. Results The prevalence of depression disorder was 3.66% ; $i, Dy, Ne mean scores of freshmen with depression disorder were significantly higher than without depression disorder(t= 5. 348,3. 879,2. 997 ) (P<0.05, P<0.01)), otherwise, Do, Pc , PEI ones were significantly lower than without depres-sion disorder( t= -2.171, -2.602, -2.62) (P<0.05, P<0.01);D mean score of all subjects was significant-ly related to Si, Dy, Do, Nc, PEI,Pe(r=0.600,0.465, -0.356,0. 240, -0. 353, -0. 146) (P<0.05, P<0.01 ). And also Si,Do,Pc,Nc got into regression quotation. Condusion Freshmen's depression is associated with their personalities,coping style and self-consciousness, however,their personalities, coping style were most important pre-dictors.

Objective To evaluate the treatment of supra-condylar fractures of the humerus (12-B1.2 by AO classification) with a unilateral external fixator. Methods From 2003 to 2006,28 cases of supra-condylar fractures of the humerus were treated with a unilateral external fixator. They were 15 males and 13 females. Their average age was 43 (24 to 58) years old. They were all closed fractures and 2 cases complicated with radial nerve injury. Results All were followed up for an average of 28 (12 to 54) months. All fractures united with an average healing time of 4.5 months. The 2 cases of radial nerve injury recovered completely. Five cases had infection of pin holes. The patients had an average elbow score (Money and Bryan system) of 97 and an average shoulder score (Constant and Murley system) of 98. Conclusion The unilateral external fixator is appropriate for supra-condylar fractures of the humerus ( 12-B1.2 by AO classification),because it provides not only effective fixation but also early functional rehabilitation.

Objective To explore the role of intravenous nutrition and enteral nutrition in the treatment of gastroplegia after gastrectomy. Methods The clinical data of 63 cases of gastroplegia after gastrectomy were retrospectively analyzed. Among the 63 cases, 30 were treated by gastrodynamic drugs and intravenous nutrition(intravenous nutrition group), and the other 33 cases were treated by gastrodynamic drugs and enteral nutrition(enteral nutrition group). Gastrointestinal decompression amount and recovery time of gastroplegia between the two groups were compared. Results Enteral nutrition group had a short recovery time of gastroplegia and less gastrointestinal decompression amount compared with intravenous nutrition group(P

Notch signaling is an important evolutionarily conserved pathway involving the fate of cells translation. Additional?ly, this pathway also plays an important role in cartilage formation and maintenance of chondrocytes phenotype, regulation of the prolif?eration, maturation and balance of cartilage matrix metabolism. This paper reviews the composition and activation process of notch sig?naling, and its specific role in cartilage formation.

Objective To investigate the relationship between the expression of Fas, FasL, Bcl-2 and Bax in transitional cell carcinoma of bladder and its clinical significance. Methods Immunohistochemistry method was used to detect the expression of Fas, FasL, Bcl-2 and Bax in 40 specimens of transitional cell carcinoma of bladder and 24 specimens of normal bladder mucosa tissue. Results The positive expression of Fas was detected both in transitional cell carcinonma of bladder and in normal bladder mucosa tissue, while FasL, Bcl-2 and Bax only in transitional cell carcinonma of bladder. The expression of Fas was significantly lower in careinoma of high-grade malignancy than in carcinoma of low-grade malignancy (P

30,BMI≥25 kg?m -2 ),who were admitted to the hospital from Apr.2004 to Sep.2005,were induded in the study.They underwent CPAP.The PSG and leptin,ghrelin,true insulin,fasting blood glucose are measured before the treatment,and one week and six months after the treatment.Results After one week,there was a little decrease of leptin and ghrelin,and no change in true insulin and fasting blood glucose.After six months,only 16 patients improved a lot in AHI and hypoxemia.There was significant decrase of leptin and ghrelin and also a change of true insulin.Conclusion These data indicate that the elevated leptin and ghrelin levels are not determined by obesity alone,since they decrease during CPAP therapy.The glucose metabolic disturbance and insulin resistance in OSAS are improved after 6 months of CPAP therapy.Therefore,we can think that OSAS patients have metabolic disturbance of leptin and ghrelin,which is one of factors of obesity.
