Objective To study changes of aspartate(ASP) and glutamaic acid(GLU) in cerebral cortex of neonatal Sprague-Dawely(SD) rats after hypoxia-ischemia and nitric oxide synthase(NOS) immunoactive expression in cerebral neurons were examined to explore mailuoning′s protective effect on hypoxia-ischemia brain damage(HIBD).Methods The HIBD model was established as follows.The right common carotids of the neonatal SD rats 7 days were temporaily ligatured for 1 hour.Then the neonatal SD rats were exposed to 8% oxygen and 92% nitrogen gas mixture for 2 hours. The ASP and GLU were determined in right cerebral cortex using chromatograph,compared with sham-operated group and mailuoning administrated. Ultrastructure changes of neurons in the right cerebral cortex of neonatal SD rats were observed after sham-operated,hypoxia-ischemia and mailuoning administrated using electronmicroscope.Results The level of excitatory amino acid was promoted in right cerebral cortex after hypoxia-ischemia.The volume of excitatory amino acid was reduced sharply mailuoning administrated. Ultrastructure of neurons in the cerebral cortex showed serious injure after hypoxia-ischemia and ultrastructure of neurons in the cerebral cortex appeared slight damage.Conclusion Mailuoning may possess protective effects to the neurons after hypoxia-ischemia through supplying blood to neurons reducing release of excitatory amino acid.

Objective To evaluate the value of reconstruction of three-dimentional CT in development dislocation of hip(DDH)in children.Methods Twelve cases of DDH concluded 4 bilateral and 8 unilateral cases.To sum up,16 sick hips were operated and 8 normal hips were also obtained by three-dimensional CT(Hip speed Fi/x,GE Co).Results 3D reconstruction were used to show femoral head,(acetabulum) and relationship of acetabulum and femoral head respectively.The difference between FNA measurement of sick hips and those of normal hips were significant(P

Objective To investigate the clinical epidemiologic features of transient synovitis(TS) of hip in children occurred in Shen-zhen district.Methods The medical files were reviewed and a standard questionnaire was filled according to the conditions of 705 cases such as pathogeny,clinical manifestation,therapy and prognosis.Results Transient synovitis occurred in a sporadic form all the year round.The peak age of patients with TS was 3-7 years old.The ratio of boys to girls was 2.9:1.About 19.3% patients were attacked an upper respiratory tract infection and 11.9% patients attributed the symptoms to trauma or severe activities before 1 week.A varying degree of painful limp and restriction of movement at the hip were found clinically.All of cases were cured by skin traction.The incidence of recurrence was 6.95%.Conclusions Male predominance is found in TS.It is characteristic of sporadic form in the 4 seasons and intently relation to an upper respiratory tract infection and trauma or severe activities.TS is recurrent and the prognosis is good by skin traction.

Objective To discuss the indication and complication of overhead traction of olecranon for displaced extension-type GartlandⅢ supracondylar fracture of the humerus in children.Methods Total of 87 patients(Gartland Ⅲ) proceeded with overhead skeletal traction of ulnar olecranon,including 68 cases of ulnar deviation and 19 cases of radial deviation.Eighteen cases had complicating revolve deviation.According portable X-ray results in the 2nd and 5th,three-dimension adjustment was performed within 1 week.Five patients were treated by open reduction because of symptoms nerves and blood vessel compression.When X-ray examination showed good callus formation and stable reduction,the patient was discharged after the elbow was stabilized in flexion position with plaster fixation,which was removed in 2 weeks.Results Sixty-seven of 87 patients were followed-up for 18 months.All of them had excellent results except one who had permanent ulnar nerve injury.No cubitus varus was observed.Conclusions The overhead olecranon skeletal traction is a simple,effective method,because it can increase joint motion,relieve elbow swell and pain rapidly,and improve upper limb line of traction.However,open reduction shall be done promptly if there is evidence of nerve,blood vessel or soft tissue between broken ends of fractured bone within 5 days.

Objective To explore the expression of HCK gene during the cardiomyocyte differentiation of mouse embryonic stem cells and analyze the role of HCK gene in maintenance of pluripotency of embryonic stem cells.Methods Mouse embryonic stem cells were cultured,then induced to differentiate into cardiomyocytes.Total RNAs were isolated from mouse embryonic stem cells in the differentiation days:0 day(D0),the second day(D2),the fourth day(D4),the sixth day(D6),the eighth day(D8),respectively.The levels of HCK mRNAs were assessed by the method of semi-quantitive reverse transcriptase-polymerase chain reaction(RT-PCR).In the meanwhile,Total proteins were also isolated from mouse embryonic stem cells in the differentiation D0,D2,D4,D6,D8,and the levels of HCK proteins were evaluated by Western-blot.Results HCK mRNAs could be detected in the mouse embryonic stem cells in D0 and D2,however,they were undetectable from D4 to D8.The expression of HCK mRNAs was rapidly down-regulated during cardiomyocyte differentiation of mouse embryonic stem cells.Expression of HCK proteins,which coincided with HCK mRNAs,down-regulated during differentiation and couldn't be detected in D4.Conclusions With the cardiomyocyte differentiation of mouse embryonic stem cells,the expression of HCK in the levels of mRNA and proteins are sharply down-regulated;HCK may play an important role in maintaining the pluripotency of embryonic stem cell.

OBJECTIVETo investigate the influence of enteral administration of carbachol on the intestinal dysfunction of both severely burn patients and rabbits with partial intestinal ischemia/reperfusion (I/R) injury.

METHODSSeventy-five white rabbits were inflicted with I/R injury and randomized into intestinal I/R (I, n=25), carbachol [C, n=25, with 3g/L carbachol (3 mg/kg) injection into duodenum 1 h after SMA occlusion] and sham operation (SO, n=25, with SMA isolation but no occlusion) groups, and 5 other as normal controls. The blood flow of intestinal mucosa was detected before and after SMA occlusion or admission of carbachol. Changes in diamine oxidase (DAO), D-lactate, xylopyranose absorption, blue dextran discharging time were measured at 2, 4, 6, 8, 24, 48, 72 h after SMA occlusion. In addition, eight severe burn patients with TBSA of 84 +/- 12% were enrolled in the study, and carbachol (15 microg/kg) was administered to patients when abdominal distension or bowel sound was lower than 2 times/min, then the number of abdominal distension and bowel sounds per minute were observed.

RESULTSThe blood flow in intestinal mucosa of rabbits without SMA occlusion was (102 +/- 5) PU, reduced to (48 +/- 6) PU after SMA occlusion, and increased to (77 +/- 3) PU after injection of carbachol. The plasma DAO activity and D-lactic acid content in I group began to increase 4 hours after SMA occlusion, and they reached the peak 24 hours after SMA occlusion (4.63 +/- 0.27 U/ml, 7.9 +/- 2.4 mg/L) , after that they decreased gradually, but still higher than the normal value (0.89 +/- 0.14 U/ml, 2.0 +/- 1.1 mg/L, P < 0.05). In carbachol group, data showed the same trends as that in intestine I/R group with lower values, while no obvious changes were in sham operation group (P > 0.05). The content of D-lactic decreased dramatically 2 hours after D-lactic administration in both I and C groups, increased 6 hours after SMA occlusion, then decreased gradually, but it in C group was always higher than normal values, and little fluctuation was in sham operation group. There was no blue dextran discharge 2 hours after SMA occlusion. The discharging distance increased 6 hours later, but it was obviously shorter than the normal value 24 hrs after operation (P < 0.05) , then it returned to normal 48 to 72 hrs after operation. In the C group, blue dextran discharge was found immediately after its injection, with obvious increase in the discharging distance to peak value (43 +/- 6 cm) 6 hours after injury, and returning to normal (28 +/- 3 cm) gradually. In severe burned patients, the bowel sounds was (1.6 +/- 1.1) per minutes before carbachol administration, then increased dramatically to (6.9 +/- 1.7) per minutes 10 mins after administration, reached to a higher level 30 minutes after administration (8.3 +/- 2.4 ) times/min, and it maintained to (6.1 +/- 1.3) times/min 1 hour after administration. Abdominal distension was ameliorated 2 hours after carbachol administration, six patients were able to defecate.

CONCLUSIONEnteral administration of Carbachol can increase the blood flow of intestine mucosa, help to improve the movement, absorption and barrier functions of intestine, and ameliorate intestinal dysfunction in patients with severe burns.
