Objective To explore the effect and mechanism of early using specific immune RNA (iRNA) for preventing burn infection.Method 129 patients with serious burn were randomly divided into two groups by double blind method. The control group (n=64) was treated with routine method; The therapeutic group(n= 65) was given specific iRNA in addition to the routine therapy. The incidence of infection in two groups were investigated; Meantime, with the methods of monoclonal antibody (McAb) APAAP, 3H- TdR incorporation and MTT colorimetery, the various immune functions of patients were determined. Result (1) the incidences of wound infection and bacteriemia after burn in the therapeutic group were markedly lower than those of the control group; (2) the therapeutic group was also superior to the control group in the general condition and time of the wound healing; (3) on the l0th day postburn, the various immune founction tested in the therapeutio group have approximately restored to the normal levels, while those in the control group were still in low levels. The difference between the two groups was statistically significant (P＜0.01). Conclusion Specific iRNA, which, when used early after burn, can reduce the incidence of postburn infection, and improve immune functions of burned patients.

Objective To evaluate the clinical effects and immune function of shenqi 11 flavor capsule as an adjuvant treatment in advanced NSCLC patients during chemotherapy.Methods 58 cases of advanced NSCLC were divided into two groups by mean of digital random table method,with 29 patients in each group.GP scheme chemotherapy was applied to patients in group B,using gemcitabine (1000 mg/m2) on the 1st and 8th day intravenously (procedure should be finished within 30 minutes) and cisplatin (75 mg/m2) on the 1st day intravenously.Each cycle was 3 weeks,two cycles in total.Same scheme was applied to patients in group A and with an addition of shenqi 11 flavor capsule(1.65 g/time,3 times/d) throughout the whole procedure of chemothrapy.Recent curative effect,life quality,toxic reactions and changes in immune indexes of both groups were observed.Results Short-term response rate in group A was 48.27％ and 41.38％ in the group B (x2=0.279,P＞0.05),which showed no significant differences between the two groups.Toxic reactions such as leukopenia,hematochrome decrease and gastrointestinal reactions in the group B were significantly severe compared to group A after chemotherapy(x2 were 4.678,4.549 and 4.687 respectively,P＜0.05).As for immune indexes after chemotherapy,CD3+ (55.21 ± 3.28) ％,CD4+ (38.84±5.13) ％,CD8+ (29.86±4.83) ％,CD4+/CD8+( 1.29± 0.17) and NK cells (20.12± 2.11 ) ％in the group B indicated significant differences compared to those in group A[(62.96±4.12)％、(45.21±3.43)％、(25.23±2.79)％、(1.82±0.21)、(25.78±3.36)％],(P＜0.05).The life quality was 58.62％ in group A and 31.03％ in the group B,which showed significant difference (x2=4.462,P＜0.05).Conclusion Shenqi 11 flavor capsule as an adjuvant treatment in advanced NSCLC patients during chemotherapy can not only improve life quality of patients,alleviate the symptoms,but also enhance their immune function.

ObjectiveTo evaluate the influence of ginkgo dipyridolum injection on blood-rheological and coagulation function in pationts with AECOPD.Methods78 cases of patients with AECOPD were divided into group A (38 cases)and group B (40 cases)by mean of digital random table method.The routine treatment including oxygen inhalation,spasmolytics and anti-infection was given to patients in both groups while ginkgo dipyridolum injection (30 ml/d)was additionally added to patients in group B for two weeks.The blood-rheological and coagulation function were evaluated.ResultsAs for blood-rheological after the treatment,whole blood high shearing viscosity(5.25 ± 1.24)mPa · S,low shearing viscosity (11.12 ±2.43) mPa · S,plasma viscosity (2.06± 0.14 ) mPa · S and hematocrit (45.52 ± 2.78) ％ in the group A indicated significant differences compared to those in group B [ (4.83 ± 1.42)mPa· S,(8.78± 3.02) mPa · S,(1.73 ±0.21) mPa · S,(39.05 ± 3.41) ％],(P＜0.05); as for coagulation function after the treatment,PT (13.14± 1.31 ) S,APTT (30.85±5.24)S,FIB (4.99±1.04)S,D-D (1.42±0.23)mg/L in the group A indicated significant differences compared to those in group B [ (14.78 ± 3.13) S,(36.67 ± 8.12)S,(3.81 ± 0.42) S,(0.84 ±0.39) mg/L],(P＜0.05).ConclusionFor the patients with AECOPD,the ginkgo dipyridolum injection can decrease hood-viscosity,and obviously improve hypercoagulabale state.

To analyze the genetic characterization of epidemic rubella virus strains isolated in Liaoning from 2007-2012, a total of 145 rubella virus strains were isolated using Vero/Slam cell line from the patients' throat swabs during rubella outbreaks and sporadics cases in Liaoning Province from 2007 to 2012. Fragments of 945 nucleotides containing 1E gene from 145 rubella virus isolates were amplified by RT-PCR, the PCR products were sequenced and analyzed. Based on the 739 nucleotides of 1E gene, the phylogenetic trees were constructed with 32 WHO rubella reference strains of 13 genotypes downloaded from GenBank and 145 rubella virus strains. The results showed that the 145 rubella virus strains in 2007 -2012 belonged to genotype 1E, nucleotide acids and amino acids similarities were 97.2%-100.0% and 97.6%-100.0%, respectively. Compared to the 1E reference strains(Rvi/ Dezhou.CHN/02, RVi/MYS/01), the nucleotide acids and amino acids similarities were 96.6%-99.2% and 98.2%-100.0%, respectively except for one amino acid change (Val246-Ala246) of RVi/Shenyang. Liaoning. CHN/13.11/13, and Asp262-Asn262 of RVi/Shenyang. Liaoning. CHN/13.11/4 and RVi/Liaoyang. Liaoning. CHN/26. 11/2. there had no change found in the important antigenic epitope sites, the hemagglutination inhibition and neutralization epitopes of the other rubella viruses. All the 145 strains isolated had the same amino acid change (Leu338--Phe338) in E1 protein. These findings suggested that genotype 1E of rubella virus was the predominant genotype in Liaoning province. the rubella prevailed in recent six years was mainly caused by rubella viruses genotype 1E with multi-transmission routes.
