Objective To analyze the correlation of hypersensitive C-reactive protein(hs-CRP),homocysteine(Hcy) and D-dimer(D-D) with pathological change degree of coronary heart disease(CHD),and to investigate the diagnostic specificity and sensitivity of joint detection in CHD.Methods A total of 100 cases of CHD patients(experimental group) and 100 healthy subjects(control group) were enrolled,.Patients of the experimental group were divided into four groups on the basis of complications,including simple CHD group(32 cases),amalgamating hypertension group(46 cases),amalgamating diabetes group(9 cases),amalgamating hypertension diabetes group(13cases).The levels of hs-CRP,Hcy and D-D in the five groups were detected and analyzed.Results The levels of hs-CRP,Hcy and D-D in the experimental group were all higher than the control group(P<0.05).Logistic regression confirmed that three indexes were the independent risk factors for CHD.Each indicator has a certain clinical significance to the diagnosis and treatment of CHD but the value of Hcy could be better.Joint detection of hs-CRP and Hcy could be an ideal combination of detection,and the three joint detection might not be suitable for early diagnosis and treatment of CHD.The levels of hs-CRP and D-D in simple CHD group,amalgamating hypertension group,amalgamating hypertension diabetes group were all higher than amalgamating diabetes group(P<0.05).Conclusion hs-CRP,Hcy and D-D could be the independent risk factors of CHD,and joint detection might be with important clinical value for diagnosis of CHD.

Objective Allergic rhinitis (AR) is studied extensively while nonallergic rhinitis (NAR) insufficiently in the recent years .The aim of this study is to describe the inflammation characteristics of different types of NAR . Methods Using the skin prick test , we investigated the characteristics , nasal cytokine levels , serum cytokine levels , and the proportion of peripheral blood Treg cells in 12 cases of AR, 10 cases of NAR with eosinophilia (EOS) syndrome (NARES), 12 cases of NAR without ES (NAR), and 11 control adults . Results The NARES patients had a signifi-cantly higher level of IFN-γ(28.89 [10.97-127.07] pg/mL) than the control (8.98 [7.88-14.90] pg/mL) and the NAR patients (7.92 [7.67-45.85] pg/mL) ( P<0.05) but a lower level of nasal IL-10 than the control ([3.97±0.68] vs [4.80±1.32] pg/mL, P<0.05) .The contents of nasal IL-4, serum IL-4, nasal IL-17 and ser-um IL-17 were all markedly higher in the AR and NARES groups than in the control (P<0.05).The proportion of CD4+CD25+FOXP3+Treg cells in the CD4+T cells in the peripheral blood was (4.5±1.3)%in the AR group and (4.0±1.8) %in the NARES group, both significantly lower than (6.5±1.0) %in the control group (P<0.05) and (6.5±1.0) %in the NAR group (P<0.05). Conclusion NAR was classified according to the EOS level into NARES and NAR without EOS, which had different mechanisms and manifestations of inflammation and similar inflammatory manifestations of Th 2 and Th17.The classification of rhinitis by the level of EOS has more practical significance .

Objective Nonallergic rhinitis with eosinophilia syndrome (NARES) is associated with such diseases as bronchial asthma , nasal polyps , and aspirin intolerance , but there is a lack of studies on its inflammatory conditions .The aim of this study is to describe the inflammation characteristics of NARES . Methods This study included 101 cases of allergic rhinitis ( AR) , 39 cases of NARES, and 162 adult controls .We analyzed the inflammation char-acteristics of the patients using skin prick test ( SPT) , nasal douche , fractional exhaled nitric oxide ( FeNO ) measurement , serum eosino-phil (EOS) counting, serum total IgE (tIgE) determination, induced sputum detection, and nasal and bronchial provocation tests . Results Compared with the controls , the NARES and AR groups showed significant increases in the positive rate of nasal provocation (32.1%vs 69.2%and 75.2%, P<0.05), positive rate of bronchial provocation (1.2%vs 10.3%and 14.9%, P<0.05), and FeNO level ([15.70 ±5.20] ppb vs [37.25 ±22.95] and [39.00 ±24.29] ppb, P<0.05), as well as in the serum EOS and tIgE levels, EOS count, and ratio of EOS in the induced sputum (P<0.05).However, the level of serum tIgE was significantly lower in the NARES than in the AR group (53.3 [23.3-186.0] kU/L vs 197.0 [62.6-391.0] kU/L, P<0.05). Conclusion NARES is a syndrome with nasal, lower airway, and systematic inflammation, similar to AR in inflammatory intensity.Therefore, for patients with NARES, attention should be paid not only to upper airway but also to lower airway and systemic inflammation .

A comparative observation about histological and histochemical study were made onthe preservating methods of local ischemic kidney of dogs.The methods of this exp-eriment were divided into five groups:A.Local hypothermia;B.Hypothermic perfu-sion solution 500ml,4℃,containing Procaine 450 mg and Heparin 100 mg,infusedinto renal artery;C.Hypothermic perfusion solution 500ml,4℃,containing 20% Ma-nniton 32ml,25% MgSO_4 0.36 ml,Heparin 100 ml,infused into renal artery;D.Localhypothermia and heparin 30 mg injected into the same vessel.E.Local room tem-perature.The specimens were taken from the kidneys of the experimental dogs atvarious period after treated with every method.The results were as follows;A,D and E group presented irreversible histological changes within 4 hoursaftertreatment.Four hours later,the reaction of SDH,ATPase,AlPase werenegative.It suggested that the kidney damage was serious,as well as expressed thatthe effect of these preservating methods for ischemic kidney are not satisfactory.In B group,the histological and histochemical alteration is very light and almostreversible,during 60 days after treatment.In C group,hypothermic perfusionsolution containing Mannitol,MgSO_4 etc either during experiment or follow observa-tion for 60 days,no histological and histochemical alterations were found.It indica-ted that this method is an ideal perservating technique for ischemic kidney.

Objective: To investigate the effect of nucleophosmin 1 (NPM1) mutant A on TGF-β1-induced K562 cell proliferation and AKT phosphorylation. Methods: K562 cells were infected with Ad5-NPM1 to create an NPM1 over-expression cell model. NPM1 levels were determined by ELISA and Western blot analysis. The levels of AKT and P-AKT were determined by Western blot. MTT was used to measure the proliferation of K562 cells. Results: NPM1 protein levels in K562 cells increased in an Ad5-NPM1-MOI-dependent manner. Cell proliferation and NPM1 levels in the supernatant were significantly increased in K562 cells infected with Ad5-NPM1-30 and Ad5-NPM1-100 compared to those infected with Ad5-vector-100 (P<0.01). Treatment with (10 ng/mL) TGF-β1 increased P-AKT levels, but not total AKT levels in K562 cells. TGF-β1-induced phosphorylation of AKT was significantly increased by infection of K562 cells with Ad5-NPM1-100. No significant differences were found in total AKT levels among all groups. TGF-β1 (10 ng/mL) treatment also in-creased the proliferation of K562 cells. TGF-β1-induced K562 cell proliferation was significantly increased by infection with Ad5-NPM1-100 (P<0.01). Conclusions: NPM1 improves TGF-β1-induced cell proliferation by up-regulating AKT phosphorylation levels.

Sturge-Weber syndrome (SWS) is a neurocutaneous syndrome, characterized by the association of facial port-wine hemangiomas in the trigeminal nerve distribution area, with vascular malformation(s) of the brain (leptomeningeal angioma) with or without glaucoma. Herein, we reported Sturge-Weber syndrome in a 50-year-old man, who presented port-wine hemangiomas and epilepsy. In this case, the patient's epilepsy episodes from his first year of life had been ignored and separated from the entity of SWS by his physicians, which led to delayed treatment. This case illustrates the importance of careful examination of patients of any age with hemangiomas in the trigeminal nerve with concomitant episodes of epilepsy. In such cases, there should be yearly neuroimaging screenings to guaranteed early interdisciplinary interventions from the time of definite diagnosis.

Objective To develop anxiety scale suitable for Chinese pregnant women and evaluate its reliability and validity. Methods Based on existing research results and clinical experience,this study compiled pregnancy anxiety scale(PAS). A sample of 509 pregnant women were selected for investigation and 65 of them were randomly retested for test-retest reliability with 2 week interval. Item analysis was con-ducted to screen valid items. Then the construct validity of the scale was tested by exploratory factor analysis ( EFA) and confirmatory factor analysis(CFA). Finally the reliability and criterion validity of the scale were evaluated using Cronbach's α coefficient,retest reliability coefficient and Pearson correlation coefficient. Re-sults The PAS was composed of 27 items in four factors,including worry about delivery,worry about them-selves,worry about fetal health and general anxiety. The four factors were extracted by EFA which could ex-plain 62. 48% of the total variance. Besides,the result of CFA demonstrated that the model fitted the data with well construct validity (χ2/df=1. 89,RMR=0. 04,RMSEA=0. 06,IFI=0. 92,TLI=0. 91,CFI=0. 92, PGFI=0. 70,PNFI=0. 74,PCFI=0. 81). The score of the pregnancy-related anxiety scale and its factors scores were positively correlated with the scores of pregnancy-related anxiety questionnaire(PAQ) and child-birth attitudes questionnaire(CAQ). The correlation coefficients were 0. 60-0. 80 and 0. 50-0. 78 respectively (all P<0. 01). The Cronbach's α coefficient was 0. 93 for the total scale and that of the four factors ranged from 0. 82 to 0. 90. The test-retest reliability was 0. 68 for the total scale and ranged from 0. 54 to 0. 75 for the four factors. Conclusion The PAS has a good reliability and validity,and it can be used as a valid tool to measure the anxiety level of pregnant women.

With the development of molecular biology, biomaterials and tissue engineering, regenerative treatment of pulpal and periradicular diseases is facing new opportunities. At present, a large number of studies on dental pulp regeneration reveal that cytokines are essential for promoting migration, proliferation and osteogenic differentiation of dental pulp stem cells. In this paper, we review several kinds of cytokines related to dental pulp regeneration, and analyze their roles and regulatory mechanisms in dental pulp regeneration.

Objective:To observe the clinical features of high myopia domed-shaped macula (DSM) complicated with choroidal neovascularization (CNV) and the efficacy of intravitreal injection of anti-vascular endothelial growth factor (VEGF).Methods:A retrospective clinical study. A total of 23 eyes of 23 patients with high myopia DSM combined with CNV diagnosed by ophthalmology examination in Department of Ophthalmology of The Second People's Hospital of Foshan from January 2019 to December 2023 were included in the study.Best corrected visual acuity (BCVA), intraocular pressure, optical coherence tomography (OCT) were performed in all eyes. BCVA tests are performed using the international standard visual acuity chart, which was statistically converted to logarithm of the minimum angle of resolution (logMAR) visual acuity. DSM height, central macular thickness (CMT) and choroidal thickness (ChT) were measured by OCT. According to OCT image features, DSM was divided into horizontal and vertical elliptic bulges and circular bulges. According to the literature standard, CNV was divided into subfoveal CNV and parafoveal CNV. All patients were treated with 0.05 ml intravitreal injection of ranibizumab or conbercept (IVR or IVC). The treatment regimen was 1+ on-demand treatment. The first IVR and IVC treatment were performed on 17 eyes and 6 eyes, respectively, and were divided into IVR group and IVC group. Follow-up time ≥1 month after treatment. The clinical features of the patients and the changes of BCVA, intraocular pressure, CMT and ChT after treatment were observed. Independent sample t test was used for comparison between groups. Results:There were 23 eyes in 23 cases, 7 males had 7 eyes and 16 females had 16 eyes. There were 11 and 12 eyes in the right and left eyes respectively. Age were (49±16) years old; logMAR BCVA was 0.94±0.39. Shapes of DSM were in 13 (56.52%, 13/23), 6 (26.09%, 6/23), and 4 (17.39%, 4/23) eyes, respectively. The dome height was (97.83±46.14) μm. CMT and ChT were (276.39±98.35) and (49.48±31.66) μm, respectively. There were 17 eyes in the IVR group, including 4 males and 13 females. There were 6 cases in the IVC group, 3 cases were male and 3 cases were female. At the last follow-up, logMAR BCVA and CMT were 0.60±0.39 and (209.96±71.38) μm, respectively. BCVA was significantly increased and CMT was significantly decreased compared with before treatment, with statistical significance ( t=2.98, 2.62; P=0.005, 0.010). One month after treatment and at the last follow-up, there were no significant differences in the degree of BCVA improvement ( t=1.47, 1.35), intraocular pressure change ( t=-0.20, -0.56) and ChT reduction thickness ( t=0.80, -0.62) between IVR group and IVC group ( P>0.05). At 1 month after treatment and last follow-up, the CMT of patients in IVR group and IVC group was decreased by (57.94±67.61), (83.17±78.37) μm and (13.33±9.73), (18.17±17.88) μm compared with that before treatment, respectively, and the differences were statistically significant ( t=2.64, 3.21; P<0.05). Conclusions:IVR or IVC in the treatment of high myopia DSM combined with CNV can effectively improve BCVA. The reduction of CMT with ranibizumab is better than conbercept.

Objective　To determine the prevalence of human herpesvirus 8 (HHV-8) DNA in acute leukemia (AL) patients. Methods　The presence of HHV-8 DNA sequences in peripheral blood mononuclear cells (PBMC) and bone marrow mononuclear cells (BMMC) from 50 AL patients was examined using polymerase chain reaction (PCR). Nine human hematopoietic cell lines and PBMC from 30 normal donors were also included. Results　HHV-8 DNA sequences were detected in one case of acute myelogenous leukemia (AML). The specimens from the bone marrow aspirate, peripheral blood and serum of this patient were all positive. None of the normal donors and human hematopoietic cell lines showed evidence of HHV-8 DNA. Conclusion　The results suggest that the prevalence of HHV-8 is low in AL in China.
