【Objective】 To explore the role and significance of nucleic acid testing(NAT) in blood transfusion. 【Methods】 The NAT data from March 2015 to December 2019 were collected and analyzed by inquiring the monthly analysis table of NAT-yielding results and the information management system of Qiao Blood Station (shinow9.5). The NAT capability of Kehua and Roche nucleic acid screening systems were compared. 【Results】 A total of 19 8348 samples were screened by Kehua and Roche nucleic acid screening systems, 67 reactive samples were detected, including 65 HBV DNA reactive samples, 2 HIV RNA reactive samples, and no HCV RNA reactive sample. 151 096 samples and 47 252 samples were detected by Kehua system and Roche system, with the resolution ratio at 44.55% vs 56.25% (P>0.05) and the reactive rate at 0.032% vs 0.038 % (P>0.05), respectively. The effective resolution ratio were 42.86%, 45.45%, 50%, 40% and 57.14% each year from 2015 to 2019, and the reactive rates were 0.041%, 0.042%, 0.027%, 0.021% and 0.038%, respectively. There was no statistical significance among each year by the effective resolution ratio and the reactive rate (P>0.05). The reactive yield at resolution was the highest (77.42%, 24/31) in minipool with CT <33 and the lowest(13.64%, 3/22) in minipool with CT≥40, mostly(73.13%, 49/67) remaining in CT<35. 【Conclusion】 Both Kehua and Roche screening system can detect NAT reactive samples in enzymatic non-reactive samples. The lower the CT value of mini pool, the greater the resolution probability of reactive samples. NAT can further guarantee the safety of blood transfusion.

Objective To investigate Monilia infection and adverse pregnancy outcomes of pregnant women in labor.Methods Before informed consent,542 cases of pregnant women in labor were collected in Obstetrics Department of Maternity and Child Healthcare of Maoming City from January 2013 to April 2014,and all of these cases were examined by Monilia inspec-tion of vaginal secretions.All of these cases were 20 to 30 years old,without vaginal pathogenic infection symptoms,but in-cluded in a few of formulation of clinical features of vaginal Candida infection.With the two methods of 10% potassium hy-droxide solution wet sheet and Gram staining,if blastospore or pseudohypha of Candida mycoderma were found out in the two methods under microscope,this case was diagnosed as positive result,otherwise as negative result.Respectively choosing positive cases as observation group,and negative cases as control group,the indexes of premature rupture of membranes,per-ineum wound infection,neonatal thrush and neonatal diaper rash of the two groups were recorded.The statistical method:e-numeration data by chi-square test,measurement data using analysis of varianc.Results The positive rate of Monilia was 23.1% (125/542),higher than 19.3% reported in domestic.The incidence rates of neonatal diaper rash,premature rupture of membranes,neonatal thrush and perineum wound infection of the observation group were respectively 19.2%,8.0%, 16.8% and 12.8%,all much higher than the control group respectively was 8.4%,1.2%,3.8% and 1.7%,(χ2 =12.578~29.273,all P <0.01).Conclusion Monilia infection of pregnant women in labor could increase the chance of adverse preg-nancy outcomes.Healthy or clinical doctors should suggest that pregnant women early carry out routine examination and ear-ly treatment,in order to prevent adverse pregnancy outcomes.

【Objective】To observe the therapeutic effect of oral use of Neiyi Pill(composed of Radix Salviae Miltiorrhizae,Sanguis Draxonis,Rhizoma Sparganii,Rhizoma Curcumae,Semen Persicae,Radix Notoginseng,Radix Angelicae Sinensis,Ramulus Cinnamomi,Rhizoma Cyperi,Radix Achyranthis Bidentatae,etc.) combined with enteroclysis of Neiyi Enema(composed of Radix Salviae Miltiorrhizae,Sanguis Draxonis,Semen Persicae,Rhizoma Curcumae,Radix Paeoniae Rubra,Rhizoma Polygoni Cuspidati,etc.) for dysmenorrhea induced by endometriosis(EMS).【Methods】Fifty-eight patients diagnosed as endometriosis by laparoscopy were divided into 3 groups by randomized single-blind method.Group A(n=16) was treated with Neiyi Pill orally,Group B(n=24) with Neiyi Pill orally combined with enteroclysis of Neiyi Enema and Group C(n=18) with danazol orally.The 3 groups respectively received the corresponding treatment for 3 successive menstrual cycles(MC).Dysmenorrhea scoring was carried out according to the Guide for Clinical Research of New Chinese Herbal Medicine before treatment and after 1,2 and 3 menstrual cycles.The effects on symptoms of dysmenorrhea,lumbosacral discomfort and irritative symptom of rectum,signs of tenderness and nodule in posterior fornix of vagina and adnexal masses,and syndrome of blood stasis were observed.Meanwhile,the adverse reactions were also monitored.【Results】After treatment,effect on relieving dysmenorrhea in group B was superior to that in group C(P0.05).Effect on lumbosacral discomfort and syndrome of blood stasis in groups A and B was superior to that in group C(P0.05).Effect on irritative symptom of rectum,tenderness and nodule in posterior fornix of vagina and adnexal masses in group B was superior to that in group C(P0.05).【Conclusion】Oral use of Neiyi Pill combined with enteroclysis of Neiyi Enema has a better effect for endometriosis than only oral use of Neiyi Pill only or danazol,and has no obvious adverse reactions.

Objective To observe the effects of tetramethyipyrazine(TMP) on retina to find out whether it can protect retina from glaucomatous damage. Methods Twenty-four rabbits were randomly divided into four groups. One eye of each rabbit was model eye induced by 2％ methylcellulous, and the other was control eye. Normal saline, TMP, timolol and a combination of timolol and TMP were administrated to group A, B, C and D respectively. At the end of 4th week, eyes were excavated for light and electron microscopic study. Results The numbers of ganglion cells (P ＜0. 01) and bipolar cells (P ＜0. 01) in model eye were different significantly between group A and B. In group A, the model eye ganglion cells were karyopyknosis, chromatin margination and nuclear membrane rupture; some in ner nuclear cells dcveloped marked lytic changes; outer segment appeared disorganized; but group B changed slight ly. Conclusion The results suggest that TMP may protect retina from glaucomatous damage.

[Objective] To investigate the effect of external application of osmosis-improving herbal medicine and enema with blood-activating and stasis-removing herbal medicine for chronic pelvic inflammation. [Methods] Single-blind and randomized trial was performed on 120 cases of chronic pelvic inflammation. The cases were randomized to two groups: group A ( n = 57) was treated by enema with blood-activating and stasis-removing herbal medicine and group B ( n = 63) by the combination of enema and external application of osmosis-improving herbal medicine. Fourteen days constituted one course of treatment and the therapeutic effect was evaluated after two courses. [Results] In group A, 30 cases were cured, 21 effective, 6 ineffective and the total effective rate was 89.5%; 43 were cured, 18 effective, 2 ineffective and the total effective rate was 96.8% in group B. The result of Ridit analysis showed that the effect of group B was better than that of group A ( t = 3.08, P
