Objective To investigate the change of peripheral blooe natural killer(NK)cell subsets of patients with recurrent spontaneous abortion( RSA),in oreer to proviee the relevant scientific evieence for unexplainee recurrent spontaneous abortion( URSA) eiagnosis ane treatment. Methods Sixty-three RSA patients were raneomly eivieee into CRSA(n = 33)ane URSA(n = 30). Meanwhile 30 cases normal pregnancy women were selectee as control. Flow cytometry was appliee to eetect NK cell levels in patients with RSA ane its subsets percentage,ane then comparee to the control group. Results NK cells subset in RSA,URAS ane normal pregnancy women were(13. 77 ± 1. 53)% ,(13. 97 ± 1. 60)% ,ane(13. 65 ± 1. 74)%. There was no significant eifference among three groups( F = 0. 287,P > 0. 05). The percent of CD56 + CD16 - ,CD56 +CD16 + ,CD56 - CD16 + NK cell subsets in RAS group were:(70. 00 ± 2. 49)% ,(13. 76 ± 2. 13)% ,(7. 04 ± 1. 44)% respectively,ane(56. 50 ± 3. 94)% ,(22. 88 ± 3. 22)% ,(11. 24 ± 2. 21)% in URAS group, meanwhile(70. 48 ± 3. 21)% ,(14. 16 ± 2. 14)% ,(6. 53 ± 1. 98)% in normal pregnancy group. There was no significant eifference between RSA ane normal pregnancy group( P > 0. 05). However,There was markeely eifference between URSA with RSA or normal group(F = 182. 587,18. 118,58. 879,P < 0. 05). Conclusion NK cell activity function plays a key role in the eevelopment of URSA. The eetection of the percentage of NK cell subsets of women euring pregnancy will help RSA monitoring ane NK cell subsets can preeict the percentage change in the pregnancy outcome .

The changes of the spinal cord blood flow(SCBF),the content of TXB2 and 6-keto-PGF1a of the injured segment of the cord and other neurological manifestations were observed on a rat model of spinal cord injury(SCI)established with Allen's weight drop(50g-cm)method and the effects of indomethacin on these changes were studied.It was found that SCBF was significantly reduced in the first 2 hours after SCI and further reduced in the 4th ~ 8th hour.Increase of TXB2 was observed in the 1st hour and reached the peak in the 4th hour.The level of 6-keto-PGF1a was also increased in the 1st hour and maintained at that level for 24 hours.The changes of TXB2/6-keto-PGF1a was similar to those of TXB2.There was a negative correlation of SCHF with TXB2 content and TXB2/6-keto-PGF1a ratio.The intravenous injection of 10mg/kg indomethacin could inhibit the increase of TXB2 content and increase 6-keto-PGF1a content relatively.It could also alleviate or retard the decrease of SCBF after SCI and improve the motar function of the hind limbs of the rats.These findings suggest that indomethacin can improve SCBF and promote the recovery of neurological functions through its regulatory effects on the levels of TXB2 and 6-keto-PGF1a

Objective To observe the diameters of macular hole and destroyed boundary line between inner and outer segment (IS/OS) of the photoreceptors and the correlation with the visual acuity in patients with idiopathic macular hole(IMH). Methods The clinical data of 39 eyes (37 patients) with IMH were retrospective analyzed. All the patients had undergone the examinations of visual acuity (Snellen chart), intra-acular pressure, ocular fundus (indirect ophthalmoscope), and Fourier-domain optical coherence tomography (FD-OCT) whose speed was 27 000 A scan/s, area was 6.0 mm×6.0 mm, and the mode was 512×128. The diametres of macular hole and destroyed IS/OS, and the correlations with visual acuity were detected. Results The mean IogMAR was 0.99±0. 44 (ranged from 0. 15 to 2.00), the mean diameter of macular holes was (942.0± 348. 4)μm(ranged from 171 to 1491 μm), and the mean diameter of IS/OS disruption was (1870. 35±673.2) μm(range from 463 to 3176 μm). There was a significant correlation among the diameter of the macular hole, the diameter of the IS/OS disruption, and IogMAR in IMH (P= 0. 038, 0. 002, 0. 000). In eyes with closed macular hole after surgery, the IogMAR and the diameter of the IS/OS disruption had a significant decrease. Conclusion Using FD-OCT the photoreceptor changes can be visualized in vivo. The abnormality in the IS-OS boundary line appears to be involved for a much larger area beyond the macular hole itself, and persists there with small size even after the maeular hole closure surgery.

Objective To know the etiology distribution and drug resistance in neonate, hope to provide the reference for clinic.Methods The identification and susceptibility of bacteria were detected by culture.Results 583 bacterial strains were identified from total 560 positive samples from 2127 neonate (25.8%).The infection neonates of single bacterial and complex bacterial were 537 and 23 respectively of all 560 patients.The ratio of staphylococcus aureus, klebsiella pneumoniae and E.coli were 29.5%,22.0% and 17.0% respectively in total 560 patients.Staphylococcus Aureus of Resistance to Vancomycin(VRSA) wasn't be found.Conclusion Respiratory tract infection is the major cause of infection in newborn, including staphylococcus aureus, klebsiella pneumoniae and E.coli.

Objective To investigate the protective effect of angiotensin converting enzyme inhibitor(ACEI) and angiotensin receptor antagonist(ARB) on renal function of type 2 diabetic nephropathy patients.Methods 60 patients with type 2 diabetic nephropathy and mild or midrange damages of renal function were observed.The patients all accepted routine diabetic therapy and were randomly divided into three groups,ACEI group,ARB group and combination group with ACEI and ARB.The blood pressure,blood creatinine and urine protein of 24 hours were measured before therapy and 8 weeks after therapy.Results The excretive amounts of urine protein decreased in all groups.The excretive levels of urine protein in combination group significantly decreased than in ACEI group and ARB group(P

Objective To evaluate the clinical value of Sharp-van der Heijde score (SHS)in rheumatoid arthritis (RA).Methods Clinical and X-ray of hands data in 200 patients with RA met the ACR criteria were collected in this study.Clinical DAS28,anti-cyclic citrullinated peptide antibody (aCCP)and imaging SHS were used to evaluate the activity of RA quantitatively before and after treatment.Results A moderate correlation existed between SHS and DAS28 (r s =0.61,P =0.00),but there was no significant cor-relation either between SHS and aCCP (r s = -0.1 5,P =0.03)or between aCCP and DAS28 (r s =0.14,P =0.05 ).Significant differences before and after treatment was existed in SHS (t=24.27,P =0.00)and DAS28 (t=1 5.98,P =0.00)respectively.And there was a moderate correlation between the difference in SHS before and after treatment and aCCP (r s =0.66,P =0.00).Conclu-sion The SHS,DAS28 and the aCCP in RA are closely related.Combination of three methods will help to develop the clinical pro-grams,evaluate the efficacy and prognosis.

ObjectiveTo explore the correlation between the prevalence of benign prostatic hyperplasia(BPH) and metabolic syndrome (MS)in the army elderly.Methods Totally 1 230 veterans (aged 70 years and over) from 26 military sanatorium in Shijiazhuang city were studied.The prevalence of BPH and MS was calculated.ResultsThe prevalence of BPH among the elderly was 77.0％.There was a trend of increase in the prevalence of BPH with increasing age (x2 = 50.4,P＜0.01).The prevalence of MS among the male elderly was 19.6％.MS was a risk factor for BPH(x2 =24.2,P＜0.0001).ConclusionsMS may be one of risk factors for the prevalence of BPH.

Objective To investigate the mechanism that cause allelic dropout of amelogenin gene on X chromosome(Amel-X)when using routine Sullivan106/112 bp primer set in sex identification and discuss its influence on the forensic sex identification and the clinical diagnosis.Methods Amel-X dropout was validated with Sullivan212/218 bp and Haas-Rochholz80/83 bp primer sets.Amplification of amelogenin gene was used to analyze dropout of the Amex-X followed by sequencin.Results Sullivan212/218 bp and Hgas-Rochholz80/83 bp primer sets could be used to identify gender correctly.Three types of point mntation were observed in the forward primer binding region of the Sullivan106/112 bp primer set by sequencing in the lost Amel-X,including single point mutation at 2nd and 13th sites,respectively,and heterozygous multiple point mutations at 2nd and 13th sites.Conclusions Point mutation in the primer binding region may result in a failure to amplify amelogenin allele and thus lead to a null allele.This finding should be mid attention to because it may interfere with the sex identification.
