BackgroundResearches demonstrated that the levels of soluble CD44 (sCD44)molecule in aqueous is significantly higher in primary open-angle glaucomous(POAG) eye than normal eye,but how the sCD44 would affect the expression of apoptosis protein in trabecular meshwork cells is below understanding.Objective The present study was to investigate the effect of sCD44 on the expression of regulatory proteins bcl-2 associated death factor bad in trabecular meshwork cells in the patients with POAG.MethodsHuman scleral tissue with trabecular meshwork were obtained from POAG patients during the surgery.The trabecular meshwork cells were primarily cultured by explant culture method and identified by immunochemistry.The third generation of cells were incubated with free-serum DMEM/F12 medium added differnt dosages of sCD44 (0,1,5,10,25,50 mg/L) for 48 hours.The expression of bad protein in cultured cells was detected using cell counting kit-8 (CCK-8) as the absorbance values at 490 nm(A,90 value),and the bad protein level in cultured cells was assayed by ELISA.ResultsThe cultured cells showed the positive response for laminin ( LM ),neuron specific enolase ( NSE ),fibronectin ( FN ) monoclonal antibodies.The CCK-8 assay showed that the A490 values of the trabecular meshwork cells in 0,1,5,10,25,50 μg/L of sCD44 groups were 0.2460±0.0019,0.1874±0.0015,0.1570±0.0016,0.1302±0.0019,0.1084±0.0018,0.0940±0.0020 respectively with a statistically significant difference among the 6 groups( F =14.922,P =0.000 ),and the A490 values in various dosages of sCD44 groups were significantly lower than the 0 μg/L sCD44 group (P=0.013,0.008,0.011,0.005,0.004).The ELISA assay showed that bad protein levels in 0,1,5,10,25,50 μg/L of sCD44 groups were ( 114.8461 ± 2.9560 ),( 137.8270 ± 2.4259 ),( 161.4194 ± 3.7381 ),( 170.9453 ± 3.2006 ),( 221.2252 ±4.3738 ),( 324.6167±4.4220) ng/L,showing a total difference among them ( F =16.610,P =0.000 ),and the bad protein levels in various dosages of sCD44 groups were significantly lower than the 0 μg/L sCD44 group( P =0.017,0.013,0.008,0.007,0.006).ConclusionssCD44 can contribute to the apoptosis of the trabecular meshwork cells in patients with POAG in certain dose range by regulating the apoptosis regulatory proteins bcl-2 associated death factor bad.

OBJECTIVETo investigate the factors influencing the pregnancy outcomes of artificial insemination with donor sperm (AID), improve the pregnancy rate, and evaluate the safety of the offspring.

METHODSWe retrospectively analyzed 7,761 cycles of AID for 5,109 infertile couples performed between July 1, 2005 and June 30, 2013 in the Center of Reproductive Medicine of Shenyang No 204 Hospital, the outcomes of pregnancy, and the incidence of birth defects.

RESULTSTotally, 2 252 clinical pregnancies were achieved by AID, in which the pregnancy rate per cycle was 29. 02% and the cumulative pregnancy rate was 44. 08%. The clinical pregnancy rate was remarkably higher in the females of ≤ 35 years than in those of > 35 years old (30.31% vs 20.18%, P < 0.01), in the women with < 5-year infertility than in those with > 5-year infertility (30.83% vs 28.16%, P < 0.01), and in the patients of the ovarian stimulation group than in those of the natural cycle group (33.22% vs 28.68%, P < 0.01) The clinical pregnancy rate was the highest in the first treatment cycle (29.87%), with statistically significant difference from the fourth cycle (23.61%) (P < 0.05), but not between the other cycles (P > 0.05). There were 28 cases of birth defects in the offspring (1.40%), including 6 cases (21.43%) involving the cardiovascular system, 4 (14.29%) involving the musculoskeletal system, 3 (10.71%) involving the urogenital system, 3 (10.71%) involving the central nervous system, 2 cases (7.14%) of cleft lip and palate, 2 (7.14%) involving the respiratory system, 2 (7.14%) involving the gastrointestinal digestive system, and other anomalies.

CONCLUSIONFemale age, infertility duration, and ovarian stimulation treatment are important factors influencing the clinical pregnancy rate of AID. Artificial insemination with cryopreserved donor sperm does not increase the incidence of birth defects, which is considered as a relatively safe technique of assisted reproduction.

Objective To analyze the effects of adenohypophysis function after treating with thyrotropin releasing hormone and its clinical significance in patients with brain trauma. Methods There were 22 cases with traumatic brain injuries from July 2010 to September 2012 in Chinese people's Liberation Army nine eight hospital,after injuried within 4 to 12 hours,then 1 1 cases who were given thyrotropin-releasing hormone(TRH)were selected as experimental group,while 1 1 cases who were given the same amount of isotonic saline were selected as control group,then the score of GCS, ICS,RLS85 and the improvement of adenohypophysis function were observed. Results After treatment,the score of glasgow coma scale (GCS ), innsbruck coma scale (ICS),and the reaction level scale (RLS85)between two groups were significantly increased in three days compared with before treatment,and within three days after injury situation,the improvements of ICS and RLS85 in experimental group were better than control group(P<0.05 ). Compared with control group,the levels of each gland pituitary hormone in experimental group were significantly increased(P<0.05 ),and on the third day,the growth hormone (GH)was reduced significantly,finally 50%of that in control group. Conclusion Patients with brain injury treated with thyrotropin releasing hormone,has no significant adverse reactions,with the characteristics of safe and effective.

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.

0.05).ConclusionThe neoadjuvant radiochemotherapy can improve the sphincter-saving rate,probably can improve the resection rate and reduce the recurrence rate for the middle-lower rectal carcinoma.
