Abstract
Objective: To investigate the relationship between obstructive sleep apnea (OSA), apnea hypopnea index (AHI) and vascular injury in hypertensive patients. Methods: This cross-sectional study enrolled patients admitted to the Hypertension Department of TEDA International Cardiovascular Hospital from April 2020 to April 2023, who finished portable sleep monitoring. Sleep monitoring indicators, flow-mediated vasodilation (FMD), carotid artery ultrasound, carotid intima-media thickness, cervical and femoral pulse wave conduction velocity (cfPWV), brachial and ankle pulse wave conduction velocity (baPWV) were analyzed. OSA was classified into mild (5 times/h≤AHI<15 times/h), moderate (15≤AHI<30 times/h), and severe (AHI≥30 times/h) based on AHI levels. FMD<6.0% was defined as vascular endothelial injury, and cfPWV>10 m/s and/or baPWV>18 m/s was defined as arterial stiffness. Multivariate logistic regression analysis was used to explore the correlation between AHI, OSA severity and vascular injury, and subgroup analysis was performed in young (age≤45 years) and middle-to-old patients (age>45 years). Sensitivity analysis was performed by excluding patients with diabetes, cerebrovascular disease and coronary heart disease. The correlation between AHI and vascular injury index was analyzed by restricted cubic spline. Results: A total of 555 adult hypertensive patients were included, the mean age was (39.7±9.2) years, 422 were males (76.0%), and the prevalence of OSA was 66.7% (370/555). Multivariate logistic regression analysis showed that moderate OSA (OR=2.83, P=0.019) and severe OSA (OR=3.40, P=0.016) were positively correlated with vascular endothelial injury after adjusting for age, sex, body mass index and mean arterial pressure. Subgroup analysis showed that log AHI (OR=1.99, P=0.035), moderate OSA (OR=4.83, P=0.010) and severe OSA (OR=4.64, P=0.015) were associated with vascular endothelial injury in young hypertensive patients. The results of sensitivity analysis were similar to the above results. The results of restricted cubic spline analysis showed that AHI was correlated with FMD (P=0.022), and the slope of the curve was the largest when AHI was between 0 and 10 times/h. There was no correlation between log AHI and OSA severity and carotid intima-media thickening and arterial stiffness (all P<0.05). Conclusions: OSA is associated with vascular endothelial injury in hypertensive patients, especially in young patients.

Abstract
Hypertrophic scar is an abnormal fibrous proliferative disease that occurs after deep cutaneous injury, which not only affects aesthetics and function but also has negative psychological effects on the patients. However, the mechanism of hypertrophic scar formation has not been fully elucidated, and its clinical treatment is complex with a high rate of recurrence and no radicle cure. Intervention based on molecular targets will likely be the future direction for the prevention and treatment of hypertrophic scar. In this article, we review the specific roles and mechanisms of drug-targeted interventions in hypertrophic scar formation, including general drugs, cytokines, immunomodulators, herbal extracts, exosomes, and nanomaterials, in the context of advances in both basic and clinical research at home and abroad.

Abstract
OBJECTIVE To evaluate the efficacy and safety of 585 nm Q-switched laser in the treatment of acne inflammatory lesions and postinflammatory erythema. METHODS A total of 25 patients with moderate facial acne, symmetrical distribution of inflammatory lesions and postinflammatory erythema on both sides of the face, were enrolled. Among the 25 patients, 22 patients completed all the treatment and evaluation, and 3 patients were lost to follow-up. 585 nm Q-switched laser was used on a randomly selected side of the face for three times of treatment at a 2 week interval. The evaluations were made before each treatment, 2 and 4 weeks after the last treatment, therefore the evaluation time points were before the treatment, weeks 2, 4, 6, and 8, respectively, for a total of 5 times. Acne severity was assessed using the investigator' s global assessment (IGA) score, and erythema severity was assessed using the investigator' s subjective erythema score and narrow-spectrum reflectance spectrophotometer at each follow-up. RESULTS After 3 times of treatment, there was statistically significant difference between the IGA score in week 8 and before treatment on both sides(Z=2.64, P < 0.01; Z=2.67, P < 0.01). There was no significant difference in IGA score between the treatment side and the control side before treatment and in week 8 (P=0.59, P=0.26). There was statistically significant difference between the investiga-tor' s subjective erythema score in week 8 and before treatment on the treatment side(Z=4.24, P < 0.01), while no significant difference was showed on the control side(Z=1.73, P=0.08). In week 8, the investigator's subjective erythema score of the treatment side was lower than that of the control side (Z=3.61, P < 0.01). The erythema index of the treatment side was significantly decreased at 5 time points (P < 0.01), and the index decreased significantly in week 8 compared with the index before treatment (P < 0.01), while the erythema index of the control side was not significantly different at 5 time points. The treatment related adverse events included erythema and edema after treatment and pain during treatment, the severity was mild to moderate, which resolved spontaneously within 1 to 3 days. Nine patients were very satisfied with the treatment, 7 patients were satisfied, and 6 patients considered average. CONCLUSION 585 nm Q-switched laser has some effect in the treatment of postinflammatory erythema, and it ensures good tolerance and safety. There was no statistically significant difference between the treatment side and the control side on the improvement of acne inflammatory lesions.

Abstract
Artemisia ordosica is one of the main shrubby perennials belonging to Artemisia species of Asteraceae and could be used in folk Chinese/Mongolian medicine to treat symptoms of various inflammatory ailments. The present study was conducted to investigate the protective effects of dietary Artemisia ordosica polysaccharide (AOP) against lipopolysaccharide (LPS) induced oxidative stress in broilers via Nrf2/Keap1 and TLR4/NF-κB pathway. A total of 192 1-day-old Arbor Acres male broilers were randomly allotted to four treatments with 6 replicates (n = 8): (1) CON group, non-challenged broilers fed basal diet; (2) LPS group, LPS-challenged broilers fed basal diet; (3) AOP group, non-challenged broilers fed basal diet supplemented with 750 mg/kg AOP; (4) LPS+AOP group, LPS-challenged broilers fed basal diet supplemented with 750 mg/kg AOP. The trial included starter phase (d 1-14), stress period Ⅰ (d 15-21), convalescence Ⅰ (d 22-28), stress period Ⅱ (d 29-35) and convalescence Ⅱ (d 36-42). During stress period Ⅰ (on d 15, 17, 19 and 21) and stress period Ⅱ (on d 29, 31, 33 and 35), broilers were injected intra-abdominally either with LPS solution or with an equal amount of sterile saline. The results showed that dietary AOP supplementation alleviated LPS-induced reduction in antioxidant enzyme activity and excessive production of ROS, 8-OHdG and PC in serum of broilers challenged with LPS. Moreover, dietary AOP supplementation alleviated the decrease of T-AOC and activities of SOD, CAT and GPx in liver of broilers challenged with LPS by increasing expression of Nrf2, and inhibiting over-expression of Keap1 both at gene and protein level. Additionally, dietary AOP supplementation decreased the over-production of IL-1β and IL-6 in liver of broilers challenged by LPS through decreasing mRNA expression of TLR4, MyD88, NF-κB P65, IL-1β and IL-6, and alleviating the increase of protein expression of TLR4, IKKβ, NF-κB P65, IL-1β, IL-6, and the decrease of protein expression of IkBα. In conclusion, dietary AOP supplementation could alleviate LPS-induced oxidative stress through Nrf2/Keap1 and TLR4/NF-κB pathway.

Abstract
Objective: To establish mechanical stress-induced hypertrophic scar mouse models, and to examine the roles of interleukin-6/signal transduction and activator of transcription 3 (IL-6/STAT3) pathway and β-catenin. Methods: The experimental research method was used. Sixteen female C57/BL6 mice of 12-week-old were collected and two straight full-thickness skin incisions of 2 cm in length were inflicted on the back of each mouse. On the fourth day post injury, the two wounds on the back of each mouse were divided into mechanical traction group and blank control group according to the random number table method, with 16 wounds in each group. The wounds in mechanical traction group were given continuous mechanical traction for 14 days, while the wounds in blank control group were given no treatment. After 14 days of mechanical traction for wounds in mechanical traction group, the appearances of the scar tissue in wounds of 2 groups were visually observed, and the areas of scars were measured; the morphological changes of the scar tissue in wounds of 2 groups were observed by hematoxylin-eosin staining, and the cross-sectional areas of scars were measured; the content of IL-6 in supernatant of the scar tissue in wounds of 2 groups was detected by enzyme-linked immunosorbent assay; the protein expression of phosphorylated STAT3 (p-STAT3) of the scar tissue in wounds of 2 groups was detected by Western blotting; and the expression of β-catenin of the scar tissue in wounds of 2 groups was detected by immunohistochemistry. Data were statistically analyzed with paired sample t test. Results: Red hairless area similar to human scar tissue formed in wounds of mechanical traction group after 14 days of mechanical traction, with large area of scar, thickened local area, hardened texture, and some even slightly raised, while scar in wounds of blank control group was linear and not obvious. After 14 days of mechanical traction for wounds in mechanical traction group, the scar area of wounds in mechanical traction group was (5.65±0.95) mm2, which was significantly larger than (1.07±0.28) mm2 in blank control group (t=26.333, P<0.01). After 14 days of mechanical traction for wounds in mechanical traction group, the skin appendages of scar tissue were absent, and the dermis hyperplasia was active and obviously thickened, while skin appendages of scar tissue of wounds in blank control group were still present, with unconspicuous dermis hyperplasia; the cross-sectional area of scar in wounds of mechanical traction group was (0.82±0.23) mm2, which was significantly larger than (0.29±0.07) mm2 of blank control group (t=8.879, P<0.01). After 14 days of mechanical traction for wounds in mechanical traction group, the content of IL-6 in the supernatant of scar tissue and the protein expression of p-STAT3 in scar tissue of wounds in mechanical traction group were significantly higher than those in blank control group (t=37.552, 25.863, P<0.01). The expression of β-catenin was high in the scar tissue of wounds in mechanical traction group after 14 days of mechanical traction, while that in blank control group was low. Conclusions: The study successfully establishes mechanical stress-induced hypertrophic scar mouse models. Mechanical stress can participate in wound healing and induce scar hyperplasia of mice wounds through continuous or overexpression of IL-6/STAT3 pathway, and β-catenin can also promote the formation of hypertrophic scar.

Abstract
Objective: To investigate the influencing factors on the vaulting one month after implantable collamer lens (ICL) implantation, and to develop and verify a prediction formula. Methods: The first half of this study was retrospective case series study, and the second half was cross-sectional stydy. A total of 83 eyes of 83 patients who underwent ICL implantation in the Lixiang Eye Hospital of Soochow University were included in the first half of the study, with an average age of (27±5) years, from August 1, 2019 to December 30, 2019. All patients underwent a complete preoperative examination, including axis length, anterior chamber depth, comprehensive optometry, intraocular pressure, central corneal thickness, white-to-white diameter, horizontal and vertical sulcus-to-sulcus diameter (STS), crystalline lens thickness (LT), corneal curvature, and bright and dark pupil diameter. Multiple linear regression (stepwise) was used to develop a prediction formula. In the validation part, a total of 65 people (65 eyes) were included, with an average age of (26±5) years, from March 1, 2020 to June 1, 2020. The accuracy and reliability of the formula were verified by the intergroup correlation coefficient and Bland-Altman consistency test. Results: At 1 month after surgery, ICL size had the greatest impact on the vaulting (β=0.942, P<0.001), followed by horizontal STS (β=-0.517, P<0.001), LT (β=-0.376, P<0.001), and vertical STS (β=-0.257, P=0.017). The influence of other factors was not statistically significant (all P>0.05). The regression equation was as follows: the vaulting (μm)=-1 369.05+657.12×ICL size-287.41×horizontal STS-432.50×LT-137.33×vertical STS (the fitting degree R=0.813, R2=0.660, and corrected R2=0.643). In the verification part, the predicted average vaulting was (497.31±102.75) μm, while the actual vaulting was (514.62±152.99) μm. About 96.92% (63/65) of the patients were fitted in the moderate vault, and 3.08% (2/65) were in the high vault. The intergroup correlation coefficient was 0.581. According to the Bland-Altman test, the actual vaulting was 17.31 μm, higher than the predicted value, and the 95% confidence interval of the difference was -260.28 to 294.90 μm. Conclusion: The ICL size, horizontal and vertical STS and LT are the factors that affect and predict the vaulting one month after ICL implantation, and our prediction formula has good accuracy and reliability.

Abstract
Thirty mice were used to establish a sepsis model with cecal ligation and puncture. 15 mg/kg methylene blue or isotonic saline were injected intraperitoneally to observe liver tissue pathological changes. Changes in macrophage frequency and expressional condition of M1 and M2-type hepatic inflammatory factors were detected. After LPS stimulation, the expression level of macrophage inflammatory factor were detected. The results showed that the pathological liver injury was significantly reduced in the MB mice group (P < 0.05), and the frequency of liver macrophage was not statistically significantly different (P > 0.05). MB elevation had promoted the expression of M2-type hepatic inflammatory factor (P < 0.05) and macrophage inflammatory factor (P < 0.05). MB can play a role in preventing septic liver injury by inducing macrophages polarization to M2-type.

Methods: Twenty C57BL/6 wild-type male mice at 6-8 weeks were randomly divided into two groups: 5 in the control group, methionine-and choline-deficient diet (MCD); 15 in the experimental group, MCD diet + intraperitoneal injection of disodium chlorophosphonate liposomes (to clear macrophages). Mice were fed for 4 weeks to establish NASH model. Blood, liver and spleen were collected to analyze the body mass index, liver index, spleen index, and serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels. Non-alcoholic steatosis (NAS) activity score was evaluated by HE and Oil Red O staining. The relative expression level of F4/80 mRNA was compared by RT-PCR. Data comparison between groups was analyzed by t-test. Results: NASH model was successfully established by feeding the mice with MCD for four week. The expression of F4/80 mRNA (t = 4.167, P < 0.01), hepatic steatosis (t = 10.70, P < 0.05), interlobular inflammatory infiltration (t = 3.08, P < 0.05), and NAS score were decreased (t = 8.06, P < 0.05) in the experimental group. At the same time, ALT level [(817.00 ± 128.90) U/L vs. (231.20 ± 36.28) U/L, t = 5.71, P < 0.01], AST level [(1 211.00 ± 248.90) U/L vs. (505.30 ± 88.20) U/L, t = 3.32, P < 0.01] was decreased significantly. However, the spleen volume and spleen index of the experimental group were larger (0.24 ± 0.01 and 0.32 ± 0.02, t = 2.41, P < 0.05), and there was no significant effect on liver ballooning, body mass index and liver index. Conclusion: In NASH, phosphonate can consume macrophages to inhibit liver inflammation and protect the damaged liver.

Abstract
Patients with cyclic vomiting syndrome usually have comorbid psychological disorders, the trigger and aggravating factors of gastrointestinal symptoms. It may decrease the quality of life and the response to the conventional therapies, bring the patients to seek medical care frequently and perform unnecessary examinations, result in the waste of medical resources. We reported a 20-year-old woman with complaint of recurrent vomiting since infant, and less response to symptomatic and supportive treatment. Her vomiting relieved with antidepressant after consultation with gastroenterological specialist and psychologist. Physicians should pay more attention to recognize the comorbid psychological disorders in patients with functional gastrointestinal disorders (FGIDs), including cyclic vomiting syndrome. It is important to refer the patients with refractory symptoms to the psychologists for further professional evaluation and antidepressants.

Abstract
Objective: To evaluate the efficacy and safety of oral magnesium sulfate solution in split doses as bowel preparation in elderly patients undergoing colonoscopy. Methods: A total of 368 elderly patients undergoing colonoscopy were enrolled at PLA General Hospital. The patients were randomly divided into magnesium sulfate solution orally in split doses group (group A, n=178) and single dose group (group B, n=190). Parameters including general information, defecation frequency, Boston bowel preparation score (BBPS), detection rate of lesions and adverse reactions. Results: The frequency of defecations in group A was (7.6±1.4), more than that in group B (6.6±1.5) with statistical significance (P<0.05). The duration of bowel preparation in group A was (128.6±25.3) min, shorter than that of group B (165.4±29.7) min (P<0.05). The BBPS in group A was (8.09±0.67), better than that of group B (7.34±0.58) (P<0.05). The detection rates of intestinal polyps and micropolyps (diameter<0.5 cm) in group A were 73/178 (41.0%) and 51/178 (28.7%) respectively, compared with 58/190 (30.5%) and 37/190 (19.5%) in group B (both P<0.05). In group A, 8 patients reported adverse reactions as abdominal distension and discomfort. One patient had ST-T abnormality of electrocardiogram (ECG). No nausea or vomiting occurred, yet 2 cases needed enema for inadequate bowel preparation. Twenty-one cases in group B reported adverse events including 7 with nausea and vomiting. There were 13 patients treated with enema. Abnormal ECG was found in 4 patients in group B. The satisfaction rate of group A was 97.8%, higher than that of group B (91.6%) (P<0.05). Conclusions: The effect of bowel preparation of elderly patients with magnesium sulfate solution in split dose has a better tolerance, good cleaning effect and low incidence of adverse reactions. It is an ideal choice for the elderly to prepare colonoscopy.

Abstract
The relationship between the p38-mitogen-activated protein kinase (p38-MAPK) signal pathway and high glucose-induced hepatic stellate cell (HSC) activation was investigated in this study. Sixty human HSC samples were randomly selected and used in the control (cultured normally), high-glucose (cultured in the presence of high glucose), and blocking (cultured under high-glucose conditions in the presence of the p38-MAPK inhibitor, SB203580) groups. The cells were incubated for 120 h and subsequently analyzed for morphological changes by inverted microscopy and for a-smooth muscle actin (a-SMA) expression (to determine the degree of HSC activation) by the method of streptavidin-biotin complex and western blot. Phospho-p38-MAPK protein expression was analyzed by western blotting. a-SMA and phospho-p38-MAPK expression was significantly upregulated in HSCs cultured under high-glucose conditions, compared to the HSCs cultured normally (P < 0.01). On the other hand, phospho-p38-MAPK and a-SMA protein levels were significantly lower in the blocking group compared to the high-glucose group (P < 0.01). Based on these results, we concluded that high-glucose levels induce HSC activation mediated by phospho-p38-MAPK. Therefore, blocking the p38-MAPK signal pathway could inhibit this effect.

Abstract
We investigated the effects of glucagon-like peptide-1 receptor (GLP-1R) agonists on p38 mitogen-activated protein kinase (MAPK) signaling during inhibition of hepatic stellate cell (HSC) activity. Human HSCs were cultured and morphologically identified. HSC samples were collected and randomly divided into three groups (N = 20 samples per group): a control group treated with high glucose (final concentration 25 mM); a GLP-1R agonist group treated with liraglutide (final concentration 5 mM); and a p38-blocked group treated with the p38 MAPK inhibitor SB203580 (final concentration 14 μM). All cells were cultured for 120 h followed by detection of phosphorylated p38 MAPK (p-p38 MAPK) and α-smooth muscle actin (α-SMA, a measure of HSC activation) by western blot. p-p38 MAPK and α-SMA expression levels were both significantly lower in HSCs in the GLP-1R agonist and p38-blocked groups compared with the control group (all P < 0.01). GLP-1R agonists may inhibit the activation of HSCs by blocking the p38 MAPK signaling pathway.

Abstract
Radix bupleuri (Chaihu), the dried root of the Bupleurum plant, is an important component of traditional Chinese medicine. In this study, we examined the genetic diversity of 11 Bupleurum strains, originating from 7 provinces in China, using amplified fragment length polymorphism analysis. A total of 274 polymorphic bands were obtained using 6 primer combinations, indicating a high level of polymorphism across all strains. An estimation of the relative relationships among strains revealed genetic distances ranging from 0.2183 to 0.7372, with an average of 0.4161. The 2 most closely related varieties were Bupleurum chinense DC. strains collected from Lushi, Henan, and Zhangjiakou, Hebei, with a genetic nearness of 0.2183. Hierarchical clustering divided the strains into 3 main groups, with B. falcatum L. from Hebei and Liaoning Provinces forming a cluster that diverged from that of B. smithii Wolff. and B. chinense DC. B. falcatum L. (Sandao chaihu), collected from Heze, Shandong, clustered independently of the other strains, suggesting that this strain may have been introduced from a different location or that it arose as a result of intraspecific variation. B. smithii Wolff. (Hei chaihu) was closely associated with B. scorzonerifolium Willd. (Nan chaihu) and B. chinense DC. (Bei chaihu), suggesting a common genetic origin.

Abstract
Intraneuronal accumulation of beta-amyloid protein (Aβ) is an early pathological change in Alzheimer's disease (AD). Recent studies demonstrate that α7 nicotinic acetylcholine receptor (α7nAChR) binds to soluble Aβ with a high affinity. In vitro and in vivo experiments also show that Aβ activates p38 MAPK and ERK1/2 signaling pathways via the α7nAChR. Interestingly, it has been reported that p38 MAPK and ERK1/2 signaling pathways affect the regulation of receptor-mediated endocytosis. These data suggest that MAPK signaling pathways maybe involved in the regulation of α7nAChR-mediated Aβ uptake. However, the evidence for this hypothesis is lacking. In the present study, we examined whether Aβ1-42 oligomers activate MAPK signaling pathways via α7nAChR, and assessed the role of MAPK signaling pathways in the regulation of Aβ1-42 uptake by α7nAChR. We confirm that undifferentiated SH-SY5Y cells are capable of taking up extracellular Aβ1-42. The internalization of Aβ1-42 accumulates in the endosomes/lysosomes and mitochondria. MAPK signaling pathways are activated by Aβ1-42 via α7nAChR. Aβ1-42 and α7nAChR are co-localized in SH-SY5Y cells and the expression of α7nAChR involves in Aβ1-42 uptake and accumulation in SH-SY5Y cells. Our data demonstrate that Aβ1-42 induces an α7nAChR-dependent pathway that relates to the activation of p38 MAPK and ERK1/2, resulting in internalization of Aβ1-42. Our findings suggest that α7nAChR and MAPK signaling pathways play an important role in the uptake and accumulation of Aβ1-42 in SH-SY5Y cells. Blockade of α7nAChR may have a beneficial effect by limiting intracellular accumulation of amyloid in AD brain and serves a potential therapeutic target for AD.

Abstract
BACKGROUND The remodeling patterns in different types of chronic rhinosinusitis (CRS) have rarely been compared, particularly the difference between eosinophilic and noneosinophilic CRS with nasal polyps (CRSwNP). Moreover, whether there is a link between remodeling and inflammation remains controversial. OBJECTIVE To directly compare the remodeling features of different CRS and to explore their relationship with inflammation in Chinese patients. METHODS Histologic characteristics of surgical samples were analyzed in 33 controls, 72 eosinophilic and 76 noneosinophilic CRSwNP, and 72 CRS without nasal polyps (CRSsNP) patients. Tissue samples from 38 controls, 26 eosinophilic and 26 noneosinophilic CRSwNP, and 32 CRSsNP patients were measured for mRNA and/or protein expression of profibrotic growth factors, metalloproteinases (MMPs), tissue inhibitor of metalloproteinases (TIMPs), hypoxia-inducible factor (HIF)-1α, interleukin (IL)-8, eosinophil cationic protein (ECP), and myeloperoxidase (MPO). RESULTS The amount of collagen decreased, whereas the edema scores increased, from CRSsNP to noneosinophilic CRSwNP and to eosinophilic CRSwNP. Transforming growth factor (TGF)-β2 protein levels were enhanced in CRSsNP compared with CRSwNP. TIMP-4 protein levels decreased in eosinophilic CRSwNP compared with noneosinophilic CRSwNP and CRSsNP. The number of neutrophils decreased from CRSsNP to noneosinophilic CRSwNP and to eosinophilic CRSwNP. ECP levels were only up-regulated in eosinophilic CRSwNP. ECP levels and neutrophil number correlated positively with the severity of edema and fibrosis, respectively. Neutrophils were the major sources of TGF-β2 in CRSsNP and noneosinophilic CRSwNP. CONCLUSION Distinct remodeling patterns are revealed for different types of CRS, particularly for eosinophilic and noneosinophilic CRSwNP. Tissue remodeling associates with inflammation in CRS.

Abstract
We propose an all-fiber band-rejection filter with a tunable bandwidth, which is realized by putting a normal long-period fiber grating in series with a rotary long-period fiber grating written in a twisted single-mode fiber by CO(2) laser pulses. Bandwidth tuning is achieved by applying torsion to the composite grating. Our experimental filter shows a bandwidth tuning of approximately 16.3 nm at a rejection level of approximately 15 dB and a polarization-dependent loss lower than approximately 0.9 dB.

Abstract
OBJECTIVE To construct plasmodium falciparum cytotoxic T lymphocyte (CTL) single epitope vaccine and establish antigen presenting cells model. METHODS Gene encoding HLA-A11 restricted plasmodium falciparum CTL epitope (VTCGNGIQVR), which was in high frequency among Chinese population, was chosen and cloned into an eukaryotic expressing vector to form CTL single epitope vaccine: pcDNA3.1/beta 2m/A11. This plasmid was transfected and expressed in cell lines bearing only HLA-A11 molecule. The expressions of HLA class I molecules were accessed by flow cytometry. RESULTS The CTL single epitope was expressed in HLA-A11 cell lines and an obviously increased expressions of HLA class were detected in the transfected cell lines, and evaluated as mean channel number of fluorescence by flow cytometry (P < 0.05). CONCLUSIONS CTL single epitope expressing plasmid was constructed and the antigen presenting cells model was established. It was demonstrated that plasmodium falciparum CTL single epitope was effectively processed and expressed. Our work suggested the single-epitope vaccine might provide protection for populations which containing HLA-A11 background.
