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 .

Objective By checking on the government employees and teachers.measuring the blood pressure according to WHO,and sending the inquires papers on dangerous fact.Methods The civil servants and teachers in Dangling dis- trict were examined in October 2004.Results The result was made according to the statisitics analysis.It shows that occupation,sex,age,BMI,the history of smoking,the history of family.All these can cause the independent dan- gerous fact to the hypertensive disease.Conclusion Fat,high salt diet,smoking and drinking were all risk factors of high blood pressure.

AIM: The synergistic effect of basic fibroblast growth factor (bFGF) and endothelin- 1 (ET-1 ) on rat aortic vascular smooth muscle cells(VSMC) proliferation was observed. The possible mechanism of the synergism was also investigated. METHODS: BrdU incorporation and cell counting method were adopted to value the pro - proliferative effect of VSMC. Western- blotting was used to observe the variation of bFGF and FGFR - 1 isoforms expression. RESULTS: bFGF and ET- 1 could promote VSMC proliferation separately, and synergistically in combination. The synergism was dose - and time - dependent. ET- 1 increased all the three bFGF isoforms and FGFR - 1 protein level in dose - and time- dependent manner. In addition, after exhaustion of intracellular PKC, the upregulation effects of ET- 1 on bFGF and FGFR - 1 expressions in VSMC both inclined. CONCLUSION: bFGF and ET- 1 had synergistic effect on VSMC proliferation. ET- 1 may increase the responsiveness of VSMC to bFGF through modulation of bFGF isoforms together with FGFR - 1, which was PKC - dependent.

Gonorrhea is a sexually transmitted disease caused by Neisseria gonorrhoeae,and substantially harms human health and socioeconomic development.Due to inappropriate treatment and the presence of drug resistance genes in patients,antibiotic resistance has emerged in Neisseria gonorrhoeae,such as resistance to penicillin,tetracycline,ciprofloxacin,or other antibiotics.Currently,extended-spectrum cephalosporins (ESCs) are the first-line treatment of gonococcal infection.With the wide use of ESCs,the sensitivity of Neisseria gonorrhoeae to ESCs has been decreasing gradually,and there have been reports on cases of treatment failure in clinical practice.In order to control gonorrhea and deal with drug resistance in Neisseria gonorrhoeae,combined therapy,alternative therapy and new drugs have been developed in clinic.

To find out the risk factors of hospital infection in childhood primary nephrotic syndrome(nephrosis) and prophylactico therapeutic measures, 190 cases of child patients hospitalized for nephrosis during the period lasting from 1991 to 1999 were collected. Then a retrospective analysis of the distribution of the various risk factors was made using the single factor analysis and the logistic multi factor regression model. The hospital infection rate was found to be 34.2%, with respiratory infection accounting for 69.7%. The single factor analysis indicated that the risk factors included quantity of urinary protein per kilogram of weight within 24 hours(urinary protein), length of stay, length of hormone usage, entities of antibiotics used and length of such usage. The multi factor analysis indicated that the risk factors included urinary protein, entities of antibiotics used and length of such usage. The authors present the view that strengthening the control of respiratory diseases, setting up clean wards, and ensuring the rational use of antibiotics are some of the key measures for reducing the rate of hospital infection. The quantity of urinary protein is a sensitive index of hospital infection in nephrosis. Once diagnosis of nephrosis has been confirmed, it is necessary to use ACH in full dose and for a complete course of treatment so as to reduce the loss of protein from the urine as soon as possible.

AIM: The role of protein kinase C(PKC) in the effect of Interleukin-6(IL-6) on basic fibroblast growth factor(bFGF) expression was investigated in rat vascular smooth muscle cells(VSMC). METHODS: Western-blotting was adopted to observe the variation of bFGF and its receptor type I isoforms expression. RESULTS: IL-6 increased all the three basic fibroblast growth factor isoforms in a dose-dependent (0-10.0 ?g/L) manner. The upregulatory activities peaked at 24 h as demonstrated . In addition, after exhaustion of intracellular phorbol ester-sensitive PKC, the upregulatory effects of IL-6 on bFGF exprssion in VSMC declined ( P
