Objective To investigate the relationship between the expression of p63, p73 proteins and the development of hemangioma. Methods The immunohistochemical technique and quantitative image analysis were used to detect the expression of p63 and p73 proteins in 40 cases of capillary hemangioma and 20 specimens of normal skin. Results The absorbance value (mean ? SD) of p63 and p73 expression in normal skin tissue, proliferative phase of hemangioma and involuting phase of hemangioma were 0.923 ? 0.191 and 0.953 ? 0.120, 8.271 ? 1.953 and 6.408 ? 2.151, 0.920 ? 0.187 and 1.073 ? 0.516, respectively. The expression of p63 and p73 in proliferative phase of hemangioma was significantly increased as compared with those in involuting phase of hemangioma and normal skin tissue (P 0.05). Conclusions It is suggested that p63 gene is not a tumor suppressor gene but an oncogene in hemangioma and may contribute to the proliferation of endothelial cell and be associated with angiogenesis, and p73 may play an important role in the proliferation of hemangioma.

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.

Abstract: Objective To investigate the prevalence and genetic characterization of Blastocystis in primary and middle school students in Baisha Li Autonomous County, Hainan Province, in order to understand the infection status of Blastocystis and its subtype distribution characteristics in this area. Methods From March to November 2021, fecal samples were collected from two primary and middle schools in Baisha Li Autonomous County. Nested PCR targeting the SSU rDNA was employed in this study, sequence analysis were performed to determine the prevalence and subtype. A neighbor-joining tree was built using Mega 7. Meanwhile, the risk factors of the Blastocystis infection among different grades and genders were evaluated. Results The infection rate of Blastocystis was 4.1% (13/314), there was no statistical difference in infection rates among genders and grades (P>0.05). Sequence analysis revealed that three Blastocystis subtypes were identified, namely ST3 (n=7), ST7 (n=4) and ST1 (n=2), all of which have zoonotic potential. Conclusions This is the first report of the identification of Blastocystis in humans in Hainan at the subtype level, and provide the basic data for the prevention and control of Blastocystis in this area. The zoonotic subtypes identified in this area indicated more studies should be taken in humans and various animals, to better evaluate the transmission of Blastocystis and provide scientific support for the prevention and control of Blastocystis.

To establish an HPLC-MS/MS method for the analysis of quercetin, kaempferid and isorhamnetin in rats plasma and study its pharmamacokinetics after an intragastrical administration of Hippophae rhamnoides extracts. Five healthy male Sprague-Dawley (SD) rats were given single doses of H. rhamnoides extracts (quercetin 26.35 mg x kg(-1), kaempferid 4.040 mg x kg(-1), isorhamnetin 31.37 mg x kg(-1)), and then their orbital sinus blood samples were collected at different time points. The drug plasma concentration of the three flavonoids was determined by HPLC-MS/MS method. After that, the main pharmacokinetics parameters were calculated by using Kinetica 5. 0. 11 software. The methodological test showed that the linear concentration ranges of quercetin, kaempferid and isorhamnetin were 7.500-600.0 μg x L(-1) (R2 = 0.998 5), 1.000-80.00 μg x L(-1) (R2 = 0.998 5 ) and 10.00-800.0 μg x L(-1) (R2 = 0.998 0), respectively. The inner and inter-days precisions were both less than 14.0%. The plasma samples showed a good stability and consistency with the requirement of biological sample analysis after the samples were frozen once and placed at - 20 degrees C for 15 d and room temperature for 6 h and the treated analytes were placed at -20 degrees C for 24 h. For quercetin, the pharmacokinetic parameter t(½β), AUC(0-∞), MRT(0.∞), C.(max) and T(max) were (113.3 ± 19.37) min, (12 542.14 ± 3 504.05) μg x h x L(-1), (119.6 ± 13.29) h, (164.6 ± 27.33) μg x L(-1) and (5.199 ± 0.840 3) h, respectively. For kaempferid, the pharmacokinetic parameters t(½β), AUC(0-t), MRT(0-∞), C(max) and T(max) were (79.85 ± 17.15) min, (934.51 ± 94.59) μg x h x L(-1), (81.50 ± 13.75) h, (80.15 ± 14.24) μg x L(-1) and (3.827 ± 0.902 7) h, respectively. For isorhamnetin, the pharmacokinetic parameters t1,2,, AUC(0-t), MRT(0-∞), C(max) and T(max) were (118.3 ± 20.73) min, (26 067.77 ± 4 124.60) μg x h x L(-1), (129.0 ± 16.30) h, (269.6 ± 29.32) μg x L(-1) and (6.513 ± 1.450) h, respectively. The HPLC-MS/MS analysis method established in this study was proved to be sensitive and accurate and could be applied in the pharmacokinetic study of quercetin, kaempferid and isorhamnetin in rat plasma.

Objective To study the current situation of human brucellosis infection in a population at high risk in Qian'an,and to provide a scientific basis for prevention and control of the disease.Methods Towns with centralized residents working in sheep breeding,transporting,slaughtering and processing in Jianchangying,Muchangkou and Xiaguanying of Qian'an were selected.In each selected town,2-3 villages with relatively centralized households working in sheep farming,transportation and slaughtering were chosen.All of the people who contacted the sheep or their excrement were chosen as monitoring objects,and serological antibody was tested with rose Bengal plate test(RBPT) and serum agglutination test(SAT).Regional,gender,age and occupational distribution of brucellosis were analyzed.Results A total of 367 blood samples were tested,46 of them were positive in both RBPT and SAT with a ratio of 12.53% (46/367).Male positive rate [13.51% (30/222)] was slightly higher than that of females [11.03%(16/145)].The rate in Jianchangying was higher than that of other two towns with a ratio of 13.38%(40/299).The veterinary population had the highest ratio of 33.33%(1/3).Conclusions It is necessary to carry out the surveillance on brucellosis and to further strengthen communication with the animal husbandry department,and strengthen protection on key population.At the same time,in order to control the spread of the disease,extensive health education and intervention measures should be carried out.

OBJECTIVETo observe the effect of Chinese herbal therapy on T-lymphocyte subsets in patients with IgA nephropathy (IgAN).
METHODSTotally 36 inpatients and outpatients at Department of Nephropathy, Xiyuan Hospital, China Academy of Chinese Medical Sciences, from June 2011 to June 2013 were recruited in the treatment group, while 20 volunteers were recruited as the healthy control group. Patients in the IgAN group only took Chinese herbal decoctions by syndrome typing for 3 months (except those accompanied with hypertension additionally took antihypertensive agents such as angiotensin-converting enzyme inhibitor and/or dihydropyridines calcium antagonist). No intervention was performed in the healthy control group. The values of Th1, Th2, and CD4+ CD25+ Treg, and red blood cell number in urine were detected using flow cytometry before and after treatment. 24 h urine protein was detected using inmmunoturbidimetry.
RESULTSCompared with the healthy control group, the CD4+ CD25+ Treg level obviously decreased in the IgAN group, showing statistical difference (P < 0.01). In the IgAN group, Th1, 24 h urine protein, and urine red blood cell counts were obviously lower after treatment, showing statistical difference when compared with before treatment (all P < 0.05).
CONCLUSIONChinese herbal therapy could reduce urine erythrocyte number and 24 h urine protein of IgAN patients, and down-regulating Th1 expression might be its mechanism.
