Objective:To explore the factors affecting the antiviral treatment efficacy of acquired immunodeficiency syndrome (AIDS) patients.Methods:A total of 107 patients diagnosed with human immunodeficiency virus (HIV) infection in the clinic of Beihai People′s Hospital from January 2016 to June 2018 were selected.The patients were divided into two groups according to whether they voluntarily accepted traditional Chinese medicine treatment, including treatment group who received highly active anti-retroviral therapy (HAART) and traditional Chinese medicine prescription of Ping Gan Jie Du (42 cases), and control group who were only treated with HAART (65 cases). The virological and immunological responses were compared between the two groups at 48 weeks of treatment. The interleukin-28B (IL-28B) rs12979860 genotypes were measured by using the direct sequencing of polymerase chain reaction products. Logistic regression was used to analyze the influencing factors of antiviral efficacy in AIDS patients.Comparison between groups was performed by independent sample t test、matched sample t test or chi-square test. Results:At week 48 of treatment, 41 (97.62%) of the 42 patients in the HAART plus Ping Gan Jie Du group obtained virological response, while 58 (89.23%) of the 65 patients in the HAART group alone acquired virological response, which was not significantly different ( χ2=0.100, P>0.05). The numbers of CD4 + T lymphocytes increased at week 48 of treatment in the HAART plus Ping Gan Jie Du group and HAART group were (244.32±101.83)/μL and (211.56±112.50)/μL, respectively. The was no statistically significant difference ( t=1.522, P>0.05). Among the 92 patients with IL-28B CC genotype, 88 (95.65%) acquired virological response, while 11 of the 15 patients with non-IL-28B CC genotype acquired virological response, which was not significantly different ( χ2=0.394, P>0.05). And CD4 + T lymphocytes in patients with IL-28B CC genotype increased ((229.72±101.17)/μL), which was higher than that without IL-28B CC genotype ((173.40±89.64)/μL), with statistically significant difference ( t=2.028, P=0.045). Multivariate logistic regression analysis showed that baseline CD4 + T lymphocyte count≤200/μL, IL-28B CC genotype, and treatment plan including protease inhibitor were helpful to improve the antiviral efficacy. Conclusion:Baseline CD4 + T lymphocyte count ≤200/μL, IL-28B CC genotype, and protease inhibitor in HAART regimen are the influencing factors of antiviral efficacy in AIDS patients.

OBJECTIVETo observe the effect of Bushen Yizhi Recipe (BSYZR) on neurotransmitter release in A beta segment neurotoxin induced NG108-15 cellular model of Alzheimer disease (AD).
METHODSThe levels of choline acetyltransferase (ChAT) activity, synapsin and functional synapse formation rate in the cellular model treated with BSYZR containing serum were determined by Western blot analysis, immunoradiometric assay and electrophysiologic technique.
RESULTSBSYZR containing serum treatment could cause increase of ChAT activity and synapsin level in model cells, as compared with those in normal control model cells treated with non-drug containing serum, it also could regulate the release capacity of transmitter and raise the functional synapse formation.
CONCLUSIONBSYZR could reduce the reaction of cell to A beta neurotoxin, indicating that it could be antagonistic to the pathological development of AD by means of raising the neurotransmitter release capacity.

Objective: To observe the clinical efficacy of tuina at head and abdomen for headache due to phlegm turbidity. Methods:A total of 56 patients with headache due to phlegm turbidity were randomized into a tuina group and a Chinese medicine group by the random number table, with 28 cases in each group. The tuina group was treated mainly with tuina at the head and abdomen, while the Chinese medicine group was treated with oral administration of Ban Xia Bai Zhu Tian Ma Tang(Pinellia, Atractylodes Macrocephala and GastrodiaDecoction). The course of treatment was 30 d. The scores of headache index, traditional Chinese medicine syndrome scale, and the therapeutic efficacy were observed. Results:There were 2 dropouts in each group during treatment. The total effective rate was 92.3% in the tuina group, significantly higher than 76.9% in the Chinese medicine group (P<0.05). The scores of headache index and traditional Chinese medicine syndrome scale in both groups decreased after treatment (bothP<0.05), and scores in the tuina group were lower than those in the Chinese medicine group (bothP<0.05). Conclusion:Tuina mainly at head and abdomen is effective in treating headache due to phlegm turbidity, and has a better effect than Ban Xia Bai Zhu Tian Ma Tang (Pinellia, Atractylodes Macrocephala and GastrodiaDecoction).

Abstract:
OBJECTIVE:
To investigate the bacterial succession on rat carcasses and to evaluate the use of bacterial succession for postmortem interval (PMI) estimation.
METHODS:
Adult female SD rat remains were placed in carton boxes. The bacterial colonization of circumocular skin, mouth and vagina was collected to be identified using culture-dependent biochemical methods. The changes in community composition were regularly documented.
RESULTS:
The bacterial succession in three habitats showed that Staphylococcus and Neisseria were predominated in early PMI, especially Staphylococcus aureus and Neisseria lactamica in 6 hours after death. Lactobacillus casei developed on the 3-4 days regularly, and kept stable at a certain level in late PMI.
CONCLUSION
The involvement of normal and putrefactive bacteria in three body habitats of rat remains can be used for PMI estimation.
