Objective:To construct the general anesthesia nursing education model based on constructivism learning theory and evaluate its effect.Methods:From January to March 2021, a general anesthesia nursing education model based on constructivism learning theory was formed through literature retrieval, qualitative interview and expert argumentation. From May to August 2021, a total of 106 patients undergoing elective general anesthesia surgery in the First Affiliated Hospital of Henan University of Science and Technology were selected by convenient sampling. A total of 53 patients who met the criteria from May to June 2021 were set as the control group, and 53 patients who met the criteria from July to August 2021 were set as the intervention group. The control group was given routine preoperative health education, and the intervention group received general anesthesia nursing education model based on constructivism learning theory. The anxiety state of patients was measured with the State Anxiety Inventory (SAI) , blood pressure and heart rate, and the recovery quality of patients was measured with the Quality of Recovery (QoR-15) . Independent sample t-test was used for comparison between groups. Results:The SAI score of intervention group patients after intervention was (37.02?à3.41) , lower than that of the control group (40.60?à9.65) , and the difference was statistically significant ( t=2.550, P<0.05) . There was no statistical difference in systolic blood pressure, diastolic blood pressure and heart rate between the two groups one day before operation ( P>0.05) . There were statistical differences in systolic blood pressure, diastolic blood pressure and heart rate of the two groups before extubation and operation ( P<0.05) . There was statistical difference in heart rate between the two groups after extubation ( P<0.01) . Three days after operation, the total score of QoR-15 in the intervention group was (113.21?à5.04) , which was higher than that in the control group (107.25?à5.90) , and the difference was statistically significant ( t=5.594, P<0.01) . Conclusions:The general anesthesia nursing education model based on the constructivism learning theory can improve the anxiety and recovery quality of patients.

Objective To investigate the application effect of the collaborative noviciate teaching mode in the nursing undergraduates. Methods With the convenience sample method, 112 noviciate nursing students in the school of nursing of He'nan University of Science and Technology from September 2014 to September 2015 were included and divided into the observation group (56 students) and the control group (56 students) using the random number table. The students in the control group were taught with the conventional noviciate teaching mode. The students in the observation group were taught with the collaborative noviciate teaching mode. The noviciate nursing students in the two groups were evaluated with the comprehensive assessment questionnaire and the satisfaction questionnaire. The Professional Self-Concept of Nurses Instrument was used for the comparison of the internship nursing students in the two groups. Results The nursing skill operation score and the score of case studies of the noviciate nursing students in the observation group were significantly higher compared to the control group (t=3.15,6.07; P<0.01).The satisfaction of the noviciate mode and the noviciate effect of the noviciate nursing students in the observation group were both significantly higher compared to the control group (t=6.67,3.21; P< 0.01). The communication dimension, the skill dimension, the leadership dimension of the internship nursing students in the observation group were significantly higher compared to the control group(t=2.41,2.58,3.75;P<0.05). Conclusions The collaborative teaching noviciate mode not only promotes the noviciate effect of the noviciate nursing students effectively, and also promotes the improvement of the self-concept of the internship nursing students, which is profoundly valuable.

OBJECTIVETo investigate the distribution and proportion of subtypes of pol gene in HIV-1 epidemic strains in Guangxi Autonomous Region.

METHODS152 HIV-1 patients were enrolled from 11 cities in Guangxi Autonomous Region from 2010 to 2012 by convenient sampling. Inclusion criterias were listed as the fdlowing: HIV-1 infection was confirmed by Western blot, HIV-1 viral load >1 000 copies/ml, > 18 year-old, and without any serious illnesses. 5 ml of peripheral blood samples were obtained from each patient. The viral RNA was isolated from plasma and used for amplification of full-length pol gene by nested RT-PCR. The amplified products were sequenced. After editing and modification, all sequences were characterized for preliminary subtyping by genotyping and confirmed with phylogenetic tree constructed by MEGA 5.03 software. The recombinant identification of 2 unknown recombinant strains was determined by RIP and jpHMM at GOBICS.

RESULTSAmong 152 patients, 137 full-length pol genes were successfully amplified and 127 HIV-1 subtypes were identified. The distribution and proportion of subtypes was summarized as the following 71 cases of CRF01_AE, accounting for 55.9% (71/127), 38 CRF08_BC, 29.9% (38/127), 13 CRF07_BC, 10.2% (13/127), and 3 B (B'), 2.4% (3/127), 2 unknown recombinant strains, 1.6% (2/127). In 11 cites of Guangxi Autonomous Region, subtype CRF01_AE was the dominant strain. Among heterosexual transmitted patients and drug abusers, the proportions of subtype CRF01_AE were 67.4% (58/86) and 34.1% (14/41), respectively. There was a significance different in the distribution of CRF01_AE in different routes of transmission (χ(2)=15.07, P<0.001). In age 21- 35, age 36- 60 and age>60 groups, the proportions of CRF01_AE was 43.6% (17/39), 57.6% (38/66), 77.3% (17/22), and CRF08_BC was 43.6% (17/39), 28.8% (19/66), 9.1% (2/22), respectively, the difference in proportions was significant(χ(2)=8.48, P= 0.014). The patterns of two unknown recombinant strains were found to be CRF01_AE/B (B') and CRF01_AE/C/B(B'), respectively.

CONCLUSIONCRF01_AE was the dominant HIV-1 subtype in Guangxi Autonomous Region from 2010 to 2012, with heterosexual transmission as its main spreading route. The two unknown recombinant strains in Guangxi Autonomous Region were reconstructed by subtype CRF01_AE and CRF_BC.

OBJECTIVETo investigate the impact of heroin for antiviral treatment, drug resistance, mutation types and frequency in HIV/AIDS patients in Guangxi Zhuang Autonomous Region.

METHODSHIV/AIDS patients were recruited in Methadone Maintenance Treatment Clinics, HIV/AIDS Clinic and HIV Voluntary Counseling and Testing Center Liuzhou and Baise city from April 2008 to October 2009. The patients were grouped by the situation of antiviral treatment and use of heroin. A total of 435 HIV/AIDS patients were recruited, among which 108 cases in antiviral treatment and heroin group, 93 cases in antiviral treatment and never using drug group, 105 cases in no antiviral treatment and using heroin group, 129 cases in no antiviral treatment and never using drug group. The effect of antiviral treatment was evaluated by questionnaire survey, viral load measurement and CD4(+) T lymphocyte count. HIV-1 RNA from plasma was extracted, and then the pol genes were amplified and sequenced. The sequences were analyzed for HIV-1 genotype drug-resistance.

RESULTSFor the patients who received antiviral treatment, the viral load in heroin group was higher than that in never using drug group (lg (2.61 ± 1.24) vs lg (2.08 ± 0.80), t = 3.54, P < 0.05) , and the percentage of viral load lower than 1 000 copies/ml in heroin group was significantly less than that in never using drug group (63.9% vs 86.0%,χ(2) = 12.76, P < 0.05). For the patients who received antiviral treatment, the difference has no significance in CD4(+) T lymphocyte count between heroin group and never using drug group ((337.92 ± 181.66) vs (326.14 ± 254.98), t = 0.38, P = 0.703). For the patients who didn't receive antiviral treatment, the difference also has no significance in CD4(+) T lymphocyte count between heroin group and never using drug group ((373.73 ± 155.97) vs (337.53 ± 209.26), t = 1.47, P = 0.143). For the patients who received antiviral treatment, there was no difference in the percentage of the CD4(+) T lymphocyte count more than 350/ml between heroin group and never using drug group (48.1% vs 43.0%, χ(2) = 0.53, P = 0.466). 319 HIV-1 pol gene sequences were obtained. Among the patients who received antiviral treatment, the mutation frequency of M184V/I, T215Y/F, L210W and T69N/S in heroin abuser group were significantly higher than that in never using drug group (14.9% (11/74) vs 4.4% (3/68), 12.2% (9/74) vs 1.5% (1/68), 12.2% (9/74) vs 1.5% (1/68) and 10.8% (8/74) vs 1.5% (1/68) respectively) (P < 0.05).

CONCLUSIONUsing heroin may promote HIV replication, reducing the virological response to antiviral treatment and increasing the frequencies of drug resistance loci among HIV/AIDS patients.Heroin rehabilitation may benefit from the antiviral treatment and obtain better antiviral effect.
