The authors first make an analysis of the problems in clinical nursing quality control, including maintaining conservative points of view, sticking to backward quality control criteria, ignoring patients feelings, neg lecting clinical practice, and letting quality inspection become a mere formality. Then they argue that nursing quality managers should update their points of view and make constant innovations, revise quality evaluation criteria and emphasize the practical results of patient care, pay great attention to the psychological needs of the patients, and improve nursing expertise so as to render nursing quality control more rational, standardized and scientific.

Aim To explore the function of immune modulation of anti-HBV iRNA in patients with chronic hepatitis B(CHB) Methods Peripheral blood lymphocyte iRNA was prepared from anti-HBs positive human body with HBV complete clearance after HBV infection(h-iRNA). The effect of h-iRNA on HBV specific lymphocyte proliferative response of peripheral lymphocyte from patients with CHB was observed by using MTT method and was compared with that by HBV specific iRNA from animal immunized only by HBsAg(a-iRNA).Results Both h-iRNA and a-iRNA increased the level of peripheral lymphocyte proliferative response to HBsAg in patients with CHB to some degree. In group of HBcAg, only h-iRNA showed its enhancement of HBcAg specific lymphocyte proliferative response.Conclusions h-iRNA can increase HBV specific lymphocyte proliferative response in patients with CHB and the function of increasing HBcAg specific lymphocyte proliterative response contributes to HBV clearance .

Objective To evaluate the efficacy of calcium(Ca)and magnesium(Mg)infusions in pre- vention of oxaliplatin-induced acute neurotoxicity.Methods Fourty-two patients with advanced colorectal carcinoma were eligible for the study:21 were assigned to the Ca/Mg ann and 21 to the control arm.The Ca/ Mg arm and the control arm were comparable for patients'characteristics.Chemotherapy regimen were al- most the same in both arms.Chemotherapy regimen consisted of oxaliplatin 130 mg/m~2 on day 1,given as a 3-hour infusion in 500 ml of 5% glucose,concurrent with rahitrexed 3 mg/m~2 as a 15-minute intravenous (Ⅳ)infusion or calcium folinate(CF)200 mg?m~(-2)?d~(-1),days 1~5,5-Fluorouracil(5-Fu)500 mg?m~(-2)?d~(-1),days 1~5.Therapy was repeated every 3 weeks.The treatment consisted of Ca gluconate and Mg sulfate,1 g each, delivered i.v.over 15 min just before the oxaliplatin infusion and repeated at the same dose after the comple- tion of the oxaliplatin infusion.A specific neurotoxicity scale was used for oxaliplatin-related neurotoxicity. Results Ten patients(47.62%)had acute neurotoxicity in the Ca/Mg arm compared with 19 patients (90.48%)in the control arm(P0.05).Conclusion Ca/Mg infusions seem to reduce incidence and intensity of oxaliplatin-induced acute neurotoxicity,and they do not reduce the clinical activity of oxaliplatin,but dosage and administration schedule could be optimized.

Objective To study the effect of topical tacrolimus (FK506) on the survival of the xenogeneic transplanted hair follicles from human scalp to Wistar rats. Methods In our study, Wistar rats were used as recipients and human as donor. The black hair follicles of human scalp were harvested, and then the xenogeneic grafts were transplanted to white Wistar rats on the back. 20 couples of rats were divided in 2 groups: topical tacrolimus group (group A), and blank control group (group B). After operaton, we compared the survival time of hair follicles and their histologic outcomes in order to verify the practicability of xenogeneic transplantion of hair follicles, and the topical application of tacrolimus results.Results The mean survival time of group A was longer [(49. 9 ±7. 1) days] as compared to group B [(13. 1±1. 2) days]. The longest survival time was 65 days in group A and 14 days in group B, respectively. By comparison of the results we found that topical tacrolimus prolonged the survival time of the xenotransplanted hair follicles significantly and that tropical medication could not avoid rejection. Conclusions The immune privilege function dependent on the hair follicle anagen and axillary topical tacrolimus, can prolong the survival time of the xenogeneic transplanted hair follicles in rats significantly.

OBJECTIVE:
To investigate the level of H2-Ab1 in the nasal mucosa of mice with allergic rhinitis.
METHOD:
Twenty-four female 129/sv mice were divided into 2 groups: ovalbumin (OVA) group and control. The allergic rhinitis models were induced by classical method with OVA. After the last challenge, the pathological differences between the two groups were surveyed. The levels of H2-AB1 were measured by ELISA and quantitative real time PCR.
RESULT:
The expression of H2-Ab1 is higher in subjects with AR than that in controls (P < 0.05).
CONCLUSION
The levels of H2-Ab1 were highly increased in allergic rhinitis group, which might be associated with the pathogenesis of allergic rhinitis.

Phytoene synthase is a rate-limiting enzyme in the pathway of carotenoid biosynthesis.To aim at establishing a transformation of Ginseng callus cells, elevating the nutritive value through encouraging the composition of corresponding carotenoid,taking Ginseng callus cells as acceptor,psy gene were transformed into cells via Agrobacterium-mediated. The factors affecting genetict ransformation were also investigated seperately from concentrations of A.tumefaciens, age of Ginseng callus cells, infection time and co-culture time. PCR,PCR-Southern and RT-PCR analysis from the transferred gene plants proved that psy gene has been transferred into Ginseng callus cells and can be expressed. The content of ?-carotene was increased by an average of 26 times.A base of improving and raising the contents of carotenoid in the Ginseng callus cell was established.

Objective To study prognosis of patients with fulminant hepatitis after plasma ex- change treatment using model for end-stage liver disease(MELD)scoring system.Methods 160 pa- tients were randomly divided into plasma exchange group and control group,and MELD score was calculated according to the original formula for each patient.The efficacy of plasma exchange was as- sessed by mortality and improvement in biochemical parameters and MELD score.Results The levels of total bilirubin(TBIL),INR and MELD score of patients whose MELD scores were between 30 and 40[TBIL,(379.4?40.4)?mol/L; INR,2.5?0.2; MELD,30.8?3.8]were lower than before PE treatment[TBIL,(509.7?64.6)?mol/L;INR,3.5?0.3;MELD,37.3?3.5].The levels of TBIL and INR and MELD score of patients whose MELD scores were higher than 40 [TBIL,(595.6?61.5)?mol/L;INR,3.8?0.4;MELD,39.8?3.5]were lower than before PE treatmem [TBIL, (650.4?66.3)?mol/L;INR,4.4?0.6;MELD,45.2?4.2].The mortality of patients in PE group with MELD score from 30 and 40 was 50.0%,while it was 86.7% in control group,showing significant differ- ence between PE group and control group(P<0.01).The mortality of patients with MELD scores higher than 40 was 91.2% in PE group and 100% in control group,showing no significant difference between these two groups(P>0.05).Conclusions Plasma exchange treatment can decrease the serum TBIL level, INR and MELD score of patients with fulminant hepatitis and improve liver function.Compared with the control group,plasma exchange can significantly decrease the mortality of patients in PE group with MELD score from 30 to 40,but no effect on patients with MELD score higher than 40.
