OBJECTIVETo explore the relationship between the polymorphisms of interferon-gamma (IFN-gamma) gene intron 1 at position + 874 and Condyloma Acuminata (CA).

METHODSIFN-gamma gene single nucleotide polymorphisms (intron 1 at position + 874) were detected in 156 subjects, including 76 patients with recurrent CA (CA group) and 80 healthy controls (control group), by polymerase chain reaction with sequence specific primers.

RESULTSNo significant difference of IFN-gamma 1 + 874 was found between CA group (TT, TA, and AA frequencies were 10.5%, 34.2%, and 55.3%, respectively) and control group (TT, TA, and AA frequencies were 7.5%, 30.0%, and 62.5%, respectively) (chi2 = 0.959, P = 0.619).

CONCLUSIONIFN-gamma gene polymorphism (intron 1 at position + 874) is not correlated with recurrent CA.

Objective To investigate the immunoregulatory effect and compare the different regula- tions of bone marrow mescnchymal stem cells(MSCs)derived from both lupus(NZBWF1/J)and normal(BALB/ c)mice on T lymphocytes in vitro.Methods MSCs from NZBWF1/J and BALB/c mice bone marrow were iso- lated and expanded,and identified by the surface phenotypes.CD3~+ T lymphocytes isolated by nylon wool columns were stimulated by phorbol myristate acetate(PMA)and co-cultured with or without the two strains of MSCs for 24 h.Intracellular eytokines of T cell,such as interferon(IFN)-?,interleukin(IL)-4,IL-12,IL-6, were analyzed by flow cytometry and quantification of transcription factors T-box expressed in T cells(T-bet) and GATA-binding protein 3(GATA-3)were detected by reverse transcriptase PCR(RT-PCR).T cell apop- tosis was assessed by flow cytometry using rhodamine123.Results The results showed that a decrease of CD3~+ T cell apoptosis was seen when NZBWF1/J MSCs or BALB/c MSCs were added to T cells stimulated by PMA(P＜0.05),and an increase of TH2 cytokines by NZBWF1/J MSCs and TH1 eytokines by BALB/c MSCs were observed in the CD3~+ T cells eo-cuhured with MSCs(P＜0.05).Conclusion It is suggested that the al- teration of T subsets caused by MSCs may interfere with the systemic lupus erythematosus(SLE)development and normal MSCs may be effective in the improvement of SLE.NZBWF1/J MSCs have defective immunoregula- tory function when compared with MSCs from healthy mouse strains.

Objective:To observe the clinical effect of acupoint sticking of Chinese medicine at Shenque (CV 8) for preventing spleenstomach disharmony caused by venous analgesia pump.Methods:A total of 120 post-surgery patients using venous analgesia pump and also conforming to the inclusion criteria were randomized into 2 groups by the random number table.There were 58 patients in the control group who received conventional post-surgery nursing care,and there were 62 patients in the treatment group who received acupoint sticking at Shenque (CV 8) on the basis of conventional nursing care.After treatment,the incidences of postoperative nausea and vomiting,and abdominal bloating were measured.Results:The total incidence of nausea,vomiting and abdominal bloating in the treatment group was 11.3％,versus 39.7％ in the control group,and the difference of the incidence between the two groups showed a statistical significance (P＜0.05).In comparison of the severity of spleen-stomach dishormony which happened during 72 h after surgery,cases in the treatment group showed lower severity than those in the control group (P＜0.05).Conclusion:Acupoint sticking at Shenque (CV 8) can effectively prevent spleen-stomach disharmony caused by venous analgesia pump,which will alleviate sufferings of the patients.

Objective To observe the behavior changes and synaptic reconstruction of brain and the impact of gastrodin in rats with epilepysy induced by pentylenetetrazole.Methods Fifty Wistar rats in growth(50-70 g) were randomly divided into 5 groups:control group,Pentylenetetrazole (PTZ) group,gastrodin high dose group,gastrodin low dose group and sodium valproate group,each group had 10 rats.According to Racine classification,the behavior changes of rats and the frequency were recorded.Conventional method was adopt to perfuse cordis, fix and extract the brain,and the immunohistochemistry was used to detect synaptophysin(P38) expression in the temporal lobe and hippocampus of the brain after 4 weeks.Results 1.Four weeks after pentylenetetrazole ignited the growth period rats,the attack-level of each experimental group through comparison with each other,there was statistically significant difference(?2=35.83 P0.05).Conclusions There are mossy fiber sprouting and the formation of synaptic reconstruction in temporal lobe and hippocampus of the growth period rats repea-tedly ignited by pentylenetetrazole.Gastrodin may play a role in the formation of antiepileptic obviously,and through decreasing the expression of P38,which can inhibit the formation of synaptic reconstruction,as control seizures indirectly.

Epimutations are errors in the normal process of epigenetic regulation which can result in aberrant transcriptional silencing of a normally active gene or reactivation of a normally silent gene.Epimutations are generally considered to be somatic events and to be confined in affected tissues.However, recent studies of patients with hereditary nonpolyposis colorectal cancer(HNPCC) have showed that allele-specific hypermethylation of CpG islands in the promoter region of the MLH1 gene, one of the causes of the tumor,existed in all the tissues examined.In addition,germ-line epimutations of other tumor suppressor genes(TSGs),such as MSH2 and BRCA1,have also been reported,demonstrating that epimutations might arise in the germline(during gametogenesis or early embryonic development).The role of germ-line epimutations might be as important as germ-line mutations in human disease.We reviewed the update on germ-line epimutations of TSGs including the possible mechanisms underlying germ-line epimutations,the possibility of transgenerational inheritance.and their impact on our understanding of human disease.

OBJECTIVETo explore the relationship between latex allergen and clinical presentation as well as allergenic cross-reactivity between latex and other allergens, to know the incidence of latex allergy in Chinese children and elucidate the allergenic cross-reactivity of latex with other allergens.

METHODSTotally 265 children with allergic disorders were assayed with 13 international standard allergen agents by means of SPT.

RESULTSIn 79 children with latex allergenic SPT position, 53 were boys and 26 were girls with an average age of 5.6 years, and 14 cases had episodes occurred in winter, 14 cases in spring, 24 cases in summer, and 27 cases in autumn. Of them, 66 cases presented as asthma, 5 cases atopic skin disorders, 1 case anaphylactoid purpura, 1 case hives and 6 cases only had mild cough. Statistical analysis showed that the positive percentage of the latex SPT had no obvious relation with sex and age, but was higher in summers and autumns than in winters and springs (P < 0.01). Children with allergic symptoms had higher positive rate in latex allergenic SPT than those without them, that is, the positive percentage of the latex SPT significantly increased among children presenting with some allergic symptoms, such as asthma, hives and atopic skin disorders (P < 0.01). All the children with latex allergenic SPT position had cross-reactivity with acarid allergen, 62.0% approximately 43.0% with animal protein allergens including milk, cats, shrimp, dogs, eggs in the order of decreasing cross-reaction rate, and 10.1% - 3.8% with mold and plant farina allergens. But the cross-reactivity between latex and mold or tree farina I were not statistically significant.

CONCLUSIONThirty percent of the children with allergic disorders were latex allergenic SPT positive. Latex allergenic SPT positive results were significantly correlative to allergic clinical presentation and season, while were not relative to sex and age. The cross-reactivity of latex with acarid was most common, followed by animal protein allergens, while the cross-reactivity with mold and plant farina allergen was rare.

Objective: To evaluate the long-term prognosis of coronary artery disease (CAD) patients undergoing percutaneous coronary intervention (PCI) by risk stratification with American College of Cardiology (ACC)/American Heart Association (AHA) classification of coronary lesions. Methods: Data used in this study derived from the I-LOVE-IT 2 trial. I-LOVE-IT 2 trial was a prospective, multicenter, randomized, assessor-blinded, noninferiority study. A total of 1 255 patients in I-LOVE-IT 2 trial with only one lesion and underwent biodegradable polymer drug-eluting stent implantation were included and grouped according to ACC/AHA classification of coronary lesions, namely type A/B1 lesion group (n=184), type B2 lesion group (n=457) and type C lesion group (n=614). The primary endpoint was 48-month patient-oriented composite endpoint (PoCE), a composite of all-cause mortality, all myocardial infarction, stroke, and/or any revascularization. The secondary endpoints were target lesion failure (TLF), components of PoCE, major bleeding (bleeding academic research consortium(BARC) type 3-5) and definite/probable stent thrombosis within 48 months. The incidences of endpoint events were compared in the three groups. The multivariable Cox hazard ratio model was used to analyze the independent predictors of PoCE and TLF at 48 months. Results: Incidences of PoCE at 48 months were significantly higher in patients with type C lesion compared with patients with type A/B1 (24.43%(150/614) vs. 14.13%(26/184), P<0.05) or B2 lesion (24.43%(150/614) vs. 15.97%(73/457), P<0.05). The multivariable Cox hazard ratio model showed that the type C lesion were the independent predictors of 48-month PoCE (HR=1.59, 95%CI 1.21-2.08, P<0.001) and TLF (HR=2.31, 95%CI 1.53-3.49, P<0.001). After multivariable adjustment, the HRs of PoCE for patients with type C lesion versus type A/B1 and type B2 were 1.91 (95%CI 1.25-2.92, P=0.003) and 1.64 (95%CI 1.23-2.20, P<0.001), respectively. Meanwhile, the HRs of TLF for patients with type C lesion versus type A/B1 and type B2 were 2.45 (95%CI 1.29-4.64, P=0.006) and 2.55 (95%CI 1.62-4.02, P=0.001), respectively. Conclusions: The ACC/AHA classification of coronary lesions has good discrimination with long-term outcomes for CAD patients undergoing PCI. The type C lesion is associated with a worse prognosis, enough attention should be paid in these patients during routine clinical management.

OBJECTIVE To investigate the clinical significance of human papillomavirus in paraffin-embedded cervical cancer and precancerous lesion tissue by gene clip technology.METHODS 153 Patients with paraffin-embedded examples.DNA was extracted from paraffin-embedded tissues and amplified by polymerase chain reaction(PCR).RESULTS The positive rate of high-risk HPV of inflammation was 8.33%,CINⅠ45.83%,CINⅡ/CINⅢ 87.50% and invasive cancer 92.21%.The HPV infection rate of squamous cell carcinoma was 94.12%.The HPV infection rate of adenocarcinoma was 88.46%.Among all the patients with cervical cancer and CIN,the infection rate of HPV16,the most genotype,was 88.98%.The infection rate of HPV18,the second most subtype,was 33.06%.In addition,the minority were infected HPV52、33、59、68.Among 48 cases of cervical squamous cell carcinoma,the infection rate of HPV16,HPV18 was 93.73% and 27.08% respectively.Among 23 cases of cervical adenocarcinoma,the infection rate of HPV16,HPV18 was 82.61% and 52.17% respectively.On the other hand,all the patients with cervicitis were HPV single infection.The HPV multiple infection rate of CINⅠ,CINⅡ/CINⅢ,cervical cancer was 20.00%,28.57%,36.62% respectively.CONCLUSIONS Gene chip technology can detect multiple HPV genotypes in paraffin-embedded tissues with high sensitivity and specificity,which is useful in the pathogenesis and prevention of cervical cancer.

To investigate the influence of hydrogen sulfide (H₂S) on p38 MAPK signaling pathway during acute lung injury (ALI) caused by lipopolysaccharide (LPS), the rats were randomly divided into six groups: control group, LPS group, LPS + NaHS group, LPS + PPG (cystathionine-γ-lyase inhibitor) group, NaHS group and PPG group. The rats were sacrificed 6 h after injection and lung tissues were obtained. The structure of lung tissues and the number of polymorphonuclear leucocyte (PMN) was observed under optical microscope; the lung myeloperoxidase (MPO) activity, superoxide dismutase (SOD) activity and malondialdehyde (MDA) content were tested; intercellular adhesion molecule-1 (ICAM-1) protein expression changes were detected by immunohistochemical staining; phosphorylated p38 MAPK (p-p38 MAPK) protein expression was detected by Western blotting. The results showed that the lung injury in LPS group was observed, at the same time the MPO activity, the content of MDA, ICAM-1 and p-p38 MAPK protein expressions, the number of PMN were all higher than those in control group (all P < 0.05). Pre-injection of NaHS alleviated the changes induced by LPS, while pre-injection of PPG aggravated those alterations (all P < 0.05). ICAM-1 and p-p38 MAPK protein expressions in lung tissue were positively correlated (r = 0.923, P < 0.01). The results suggest that H2S may reduce LPS-induced ALI through inhibiting the conjugation of p38 MAPK and reducing the expression of ICAM-1.
