Abstract: Objective To investigate the correlation between persistent and non-persistent HPV infection and vaginal microecology and cervical lesions, and to provide the basis for HPV prevention and treatment. Methods In this prospective study, 229 female patients with high-risk type (HR-HPV) were selected for cervical cytology and vaginal microecological examination in the gynecological outpatient department of Baise Maternal and Child Health Hospital from January 2018 to June 2021. The patients were followed up for 1 year to detect persistent HR-HPV infection. The relationship between HR-HPV persistent infection and vaginal microecology and cervical lesions was analyzed using the HPV-negative group as a control. Results Among 229 patients with HR-HPV, there were 109 patients with persistent HR-HPV infection and 120 patients with non-persistent HR-HPV infection in 1-year follow-up, and the incidence of persistent HR-HPV infection was 47.6%. In the HR-HPV persistent and non-persistent infection and HPV-negative groups, the bacterial vaginal incidence was 20.2%, 15.0% and 8.6%, respectively; vulvovaginal candidiasis was 19.3%, 13.3% and 7.9%, respectively; trichomoniasis vaginitis was 12.8%, 9.2% and 4.5%, respectively; mixed infection was 10.1%, 6.7% and 2.7%; H2O2 detection rate was 24.8%, 18.3% and 12.0%,the positive rate of pH value was 52.3%, 40.8% and 36.4%, and microecological normal detection rate was 22.9%, 32.7% and 40.2%, respectively. There were significant differences among the three groups (χ2=10.634, 10.522, 9.010, 9.374, 10.054, 8.268, P<0.01). In the HR-HPV persistent and non-persistent infection groups, the rates of atypical squamous cell detection were 12.8% and 10.0%, and 8.3% and 4.2% for low-grade squamous cell lesions, and 4.6% and 1.7% for high-grade squamous cell carcinoma, 2.8% and 0 for squamous cell carcinoma, respectively. There was no significant difference in the composition of atypical squamous cells between the two groups (χ2=4.358, P>0.05), there were significant differences in the composition of low-grade, high-grade and squamous cell carcinoma (χ2=11.472, 12.685, 11.378, P<0.01). Spearman rank correlation analysis showed that the presence or extent of HPV infection was positively correlated with bacterial vaginosis, vulvovaginal candidiasis, trichomonal vaginitis and mixed infection (P<0.05), positively correlated with H2O2, sialdase, leucocyte esterase,pH positive and positive for all four items (P<0.05), negatively correlated with microecology (P<0.01), positively correlated with low grade, high grade and squamous cell carcinoma (P<0.01), and not significantly correlated with atypical squamous cell carcinoma (P>0.05). Conclusion Persistent cervical HPV infection is an important factor of dysregulation in vaginal microecology and aggravates the degree of dysregulation in vaginal microecology, which is related to the development of cervical lesions.

Objective To investigate the effects of deletion of adenosine A2A receptors on peripheral leukocytes on cerebral white matter lesions induced by chronic cerebral hypoperfusion.Methods Twenty-four wild type(WT) male mice were given a ? irradiation of 12.5Gy,followed by receiving bone marrow cells tail vein from female A2A receptor knocked out(KO) mice via tail vein,were assigned as KO→WT group,while those received bone marrow cells from WT female mice were assigned as WT→WT group(n=20).The efficiency of reconstitution of bone marrow cells in recipient mice was assessed 7 weeks after transplantation by PCR and immunofluorescent technique.Then,the recipient mice were subjected to bilateral common carotid artery stenosis with internal diameter of 0.18mm by external banding using microcoils at 8 weeks after transplantation.On 7d,14d and 30d after the surgery,corpus callosum,fiber bundles of Caudoputamen and optic tract were harvested from the cerebral white matter,and stained with Kluver-Barrera staining for observing the changes in nerve fibers,and with GFAP and CD11b immunohistochemistry staining for observing the proliferation of microglia and astrocytes.Results At 7 weeks after successful transplantation,the genotype of sex chromosome in peripheral leukocytes of the male recipient mice was changed into female pattern.The expression rate of A2A receptor was 9.73%?2.05% in KO→WT group and 93.82%?11.24% in WT→WT group,with significant difference between the two groups(P

Objective To observe behavioral characteristics and pathologic changes of chronic cerebral hypoperfusion in mice. MethodsTotally 62 adult C57BL/6 mice were subjected to either sham-operation (n=31) or bilateral common carotid artery stenosis using external microcoils with an inner diameter of 0.18 mm(n=31). At 30 d after the stenosis, the animals of the 2 groups (8 mice for each group) underwent behavioral test of 8-arm radial maze. In 7, 14 and 30 d, the rest mice were sacrificed for their brain tissue samples which were examined with Kluver-Barrera staining and immunohistochemical assay for markers of microglia and astroglia, glial fibrillary acidic protein (GFAP) and CD11b. In 14 d after the model establishment, Evans blue dye extravasation test was performed for the blood-brain barrier function. ResultsThe model group made significantly more errors than sham-operated group in 8-arm radial maze test at 30 d after the surgery. White matter lesions occurred and the proliferation of activated microglia and astroglia were observed in white matter in model mice after 14 and 30 d bilateral common carotid artery stenosis. The disruption of blood-brain barrier function of model mice was indicated in the evans blue extravasation test at 14 d after bilateral common carotid artery stenosis. ConclusionCognitive impairment, white matter lesions and glial activation are successfully induced after bilateral common carotid artery stenosis in mice model of chronic cerebral hypoperfusion.

Objective To investigate the effect of adenosine A2A receptor deficiency on the ischemic neuronal injury and its potential mechanism.Methods Transient(2 h)cerebral ischemia was induced by the middle cerebral artery occlusion(MCAO)in mice.Adenosine A2A receptor knockout(A2ARKO)mice and their wild-type littermates(A2ARWT)were divided into 2-hour cerebral ischemia group,cerebral ischemia with 22-hour reperfusion group and cerebral ischemia with 46-hour reperfusion group.Cerebral infarction volume was measured by image analysis of brain sections stained with cresyl violet(CV).Brain water content was evaluated with the dry-wet weighing method.The expression of calbindin D-28k(CB)and aquaporin-4(AQP4)in ischemic brain was determined with immunohistochemical methods.Results The cerebral infarction volumes in 2-hour cerebral ischemia group,cerebral ischemia with 22-hour reperfusion group and cerebral ischemia with 46-hour reperfusion group of A2ARKO mice were lesser than those in the corresponding groups of A2ARWT mice.Compared with A2ARWT mice,A2ARKO mice had more CB,lesser AQP4 expressions and lesser brain water contents.Conclusion Adenosine A2A receptor deficiency exerts the protection against ischemic brain injury both in the acute phase and reperfusion phase,and attenuates brain edema caused by cerebral ischemia,which may be due to the inhibition of intracellular calcium overload and AQP4 expression.

Objective To investigate the effect of Qingjing Capsule (QC) in treating advance menorrhea (AM) and to evaluate its safety. Methods Double- blind, double- imitating, parallel- controlled and randomized trial was performed in 63 cases of AM with deficiency- heat syndrome.Thirty- two cases was in QC group(Group A) and other 31 in Gujing pill group(Group B).The menstrual cycle, clinical symptoms and signs, basal body temperature (BBT), serum levels of estradiol (E2) and progesterone and endometrium biopsy were observed to evaluate the effects of QC. Results The short- term markedly- effective rate was 90.63% and 77.42% and the short- term effective rate was 96.88% and 93.55% in Group A and Group B respectively. The long- term markedly- effective rate was 83.87% and 67.74% and the long- term effective rate was 93.55% and 80.65% in Group A and Group B respectively. The long- term markedly- effective rate in QC group is superior to that in Gujing pill group, the differences being significant(P

Objective To explore the feature of electrical physiology and the key aspect of diagnosis in early stage of spinal muscular atrophy in infants.Method The back clinical data of the musle change of electrical physiology within 25 cases were analyzed.Results The children were ill in 1 year old,with the symptom that four limbs present symmetry and paralysing slowly,low limbs being more serious than upper limbs,the close and the distant of the four limbs.The levels of creatine kinase(CK) and lactate dehydrogenase(LDH) in serum were normal and the case unconcentrated was not seen rarely.The show of electromyogram(EMG) was that three limbs presenting wide-range losing nerve electric potential in peace state,when straingently the deadline was long and the motor unit potential(MUP) was high,when strain highly the eletric potential was decreased;the speed of nerve conduction was common.Muscle inspection was typical nervine myatrophy.Conclusion The clinical feature,the changes of muscle electrical physiology and the muscle inspection are valuable for diagnosis so as to afford reliable evidence for further gene diagnosis.J Appl Clin Pediatr,2006,21(3):167

AlM: To compare the results of 4 methods for measuring angle of exodeviation in the three types of intermittent exotropia, including when looking at indoor distance target of 6m, looking at indoor distance target of 30m, looking at outdoor far distance target, after 1h diagnostic occlusion test.
METHODS: Prospective case series study. Sixty-five patients with intermittent exotropia between June 2013 and June 2014 were enrolled in the Department of Ophthalmology, Affiliated Hospital to Qingdao University, included 37 males and 28 females with average age ( 12. 5 ± 6. 2 ) years. All the patients were measured when looking at indoor distance target of 6m, looking at indoor distance target of 30m, looking at outdoor far distance target, after 1h diagnostic occlusion test. lntermittent exotropia was divided into basic type, convergence insufficiency type and divergence excess type, which was based on the different result of between the distance and near measurements. The One-way test was applied to analyze the four methods of measuring angle of exodeviation in the three types of intermittent exotropia. LSD - t test was applied to compare the differences between each two methods in each type.
RESULTS: The distance exodeviations tested with looking at indoor distance target of 6m, looking at indoor distance target of 30m , looking at outdoor far distance target, after 1h diagnostic occlusion test were basic type (45. 4 ± 21. 0, 55. 0 ± 15. 0, 64. 68 ± 17. 7, 68. 75 ± 16. 6PD), convergence insufficiency type (33. 3 ± 14. 0, 44. 9 ± 12. 9, 43. 6±11. 8, 54. 6±11. 2PD), divergence excess type (55. 6± 17.4, 66.3±18.8, 76.9±16.4, 78.1±15.6PD). There were obviously differences between each two methods in each type ( basic type F = 9. 649, P = 0. 00; convergence insufficiency type F=6. 886, P=0. 001; divergence excess type F = 7. 989, P = 0. 00 ). Compared with looking at indoor distance target of 30m, looking at outdoor far distance target ( basic type P=0. 044, divergence excess type P = 0. 048 ) and after 1h diagnostic occlusion test (basic type P=0. 04, divergence excess type P=0. 027) had the statistical difference in the basic type and divergence excess type, and there was no obviously difference between looking at outdoor far distance target and after 1h diagnostic occlusion test ( basic type P=0. 353, divergence excess type P=0. 815). Compared with the other three measurements, 1h diagnostic occlusion test can elicit larger angle of deviation in the convergence insufficiency type.
CONCLUSlON: Both measurement with looking at outdoor far distance target and after 1h diagnostic occlusion test can elicit the larger angle of deviation in the basic type and divergence excess type; The measurement with after 1 hour diagnostic occlusion test can elicit the larger angle of deviation in the convergence insufficiency type.

OBJECTIVEThere is little knowledge on whether there is clustering of inflammatory biomarkers, such as C-reactive protein (CRP), soluble intracellular adhesion molecule1-1 (sICAM-1), and angiotensin II (Ang II), in individuals with hypertension in the Mongolian population. In the present study, we investigated this relationship in a Mongolian population in China.

METHODSA total of 2589 adult Mongolians, aged 20 years and older, were recruited as study participants. Data on demographics, lifestyle, family history of hypertension, blood pressure, and blood chemistry were collected, and inflammatory biomarkers were measured in all participants.

RESULTSThe proportion of subjects with increased levels of two or three biomarkers was significantly higher in those with hypertension (21.0% and 6.0%, respectively) than in those with prehypertension (12.7% and 0.5%, respectively) or normotension (8.1% and 0.2%, respectively). The multivariate adjusted odds ratios (95% confidence interval) of hypertension associated with increased levels of one, two or three biomarkers were 0.94 (0.72-1.22), 1.42 (0.93-2.16), and 11.08 (1.45-84.80), respectively, compared with subjects with no increase in any biomarker.

CONCLUSIONHypertension was associated with a cluster of inflammatory biomarkers in the Mongolian population.

OBJECTIVEObserve and analyze the informations of western medicine and traditional Chinese medicine in patients with coronary heart disease (CHD), in order to provide reference for clinical treatment.

METHODSelect patients with CHD in diagnosis of the first place in 17 hospitals, drug informations of these patients were analyzed using frequency method and association rules.

RESULTIn 84 697 patients,there were 47 564 males and 32 882 females. The median age was 71 years old, 76 172 patients have medicine records, including 278 kinds of western medicine and 331 kinds of traditional Chinese medicine. Aspirin was the most common used western medicine (51 132 patients, 67.08%), followed by isosorbide dinitrate, clopidogrel etc. The most common used traditional Chinese medicine was danhong injection, followed by shuxuetong injection. After classified the drugs, at the forefront of western medicine were antiplatelet drugs, nitrates drugs, statins, beta blockers, calcium antagonists, ACEI; the most used in traditional Chinese medicine was injection of blood-activating and stasis-resolving, followed by oral preparations of blood-activating and stasis-resolving medicine, Fuzheng class oral medicine, purgation medicine etc. After association rules, combination therapy among western medicine was the most common, combination of western medicine with blood-activating and stasis-resolving was very commonly, especially antiplatelet drugs and nitrates drugs.

CONCLUSIONWestern medicine in the treatment of patients with CHD was in accordance with the guidelines recommend, but with the lower utilization rate. Traditional Chinese medicine has become an important method for the treatment of CHD, promoting blood circulation and removing blood stasis is an important part of traditional Chinese medicine treatment in patients with CHD.
