The expression of ZNF191 mRNA in 31 ovarian malignant tumors and 31 normal ovary tissues were investigated by reverse transcription-polymerase chain reaction (RT-PCR). It was found that expression level of ZNF191 mRNA in malignant ovarian tumors was much less than that in normal ovary tissues (P

Background Essential hypertension (EH) and type 2 diabetes mellitus (T2DM) are frequently co- existed.Previous studies proved that EH can cause arrythmia,whereas,the arrythmia and the structure changed in hypertensive patients coexisted with T2DM are scarely reported.Objective To study the characteristics and mech- anism of arrhythmia in essential hypertension (EH) patients with type 2 diabetes mellitus (T2DM).Methods One hundred sixty eight patients were groupped as follows:EH group (n=65),T2DM group (n=31),EH+T2DM group (n=52),and normal group (n=20).The clinical data,echocardiographies and 24-hour dynamic eletroear- diogram were determined in all patients.Results 1)Arrhythmia incidence in EH+T2DM group was a statistically higher compared to EH group and T2DM group(P

Objective To investigate the correlation between the mutation in serum lipoprotein-associated phospholipase A2(Lp-PLA2) Ile198Thr, Val279Phe and cerebral infarction in Chinese Han population of Jiangsu Province. Methods One hundred fifty patients with cerebral infarction and 100 healthy controls in Chinese Han population of Jiangsu Province were recruited. The correlation between Val279Phe and Ilel98Thr mutation in Lp-PLA2 gene and cerebral infarction was analyzed using polymerase chain reaction and denaturing high performance liquid chromatography. Results The Val279Phe genotype and the mutant allele frequency in the cerebral infarction group were significantly higher than those in the control group (χ2 were 6. 31and 5. 32, respectively, all P ＜0. 05), and there was no significant difference between the Ile198Thr genotype and the mutant allele frequency in the control group (χ2 were 0. 039 and 0. 037, respectively, all P ＞0. 05). Conclusions The Val279Phe mutation in Lp-PLA2 gene may be a genetic risk factor for cerebral infarction in Chinese Han population of Jiangsu Province.

Objective To evaluate the value of serum procalcitonin (PCT) in antibiotics used for the treatment of acute exacerbation of asthma. Method From February 2007 to July 2009, a total of 158 patients with asthma were randomly (random number) assigned to PCT group ( n = 77) or to control group ( n = 81 ). The PCT levels of all patients were measured. On the bases of routine treatment, the employment of antibiotics in control group was determined by the guidebook, and patients in the PCT group were treated with antibiotics guided by the levels of serum PCT. The antibiotics treatment was employed as PCT level ＞0.25 ng/mL, and was not employed as PCT level ＜ 0.25 ng/mL. The rates of antibioties employment were observed. Results The rate of antibiotics employment in PCT group (45.4%) was lower than that of the control group (77.8%) (x2 = 17.15,P =0.000). Conclusions PCT could be used safely as guidance of antibiotics employment for the treatment of patients with acute exacerbation of asthma, leading to appropriate use of antibiotcs.

Abstract: Objective　To study the characteristics and diagnostic efficacy of Rose-Bengal plate agglutination test (RBPT), standard-tube agglutination test (SAT) and enzyme-linked immunosorbent assay (ELISA) in the diagnosis of brucellosis. Methods　A total of 489 suspected brucellosis patients with complete records, who admitted to Xing'anmeng People's Hospital from March 2020 to May 2021, were selected as the subjects. The diagnostic value of SAT, RBPT and ELISA for brucellosis was analyzed with exposure history + clinical symptoms + serological test/brucellosis isolation and culture as the gold standard. Results　Of the 489 suspected patients, 183 (37.42%) were diagnosed with brucellosis, while 234 (47.85%), 148 (30.27%) and 195 (39.88%) were positive by RBPT, ELISA and SAT, respectively. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of RBPT in the diagnosis of brucellosis were 95.08%, 80.39%, 74.36%, 96.47%, and 85.89%, respectively; the values of the above parameters for ELISA were 78.69%, 98.69%, 97.30%, 88.56%, and 91.21%, respectively; those values of SAT were 98.36%, 95.10%, 92.31%, 98.98%, and 96.32%, respectively. The sensitivity of RBPT was significantly higher than ELISA, but the specificity and accuracy were significantly lower than ELISA (all P<0.05). The sensitivity and accuracy of SAT diagnosis were significantly higher than ELISA, but the specificity was significantly lower than ELISA (all P<0.05). There was no significant difference between SAT and RBPT in the sensitivity of diagnosis, but the specificity and accuracy were significantly higher than those of RBPT (P<0.05). Conclusion　RBPT and SAT have high sensitivity in diagnosis of brucellosis, while ELISA has high specificity in diagnosis. RBPT with high sensitivity and convenient operation can be used for primary screening in field detection, and then the other two methods can be used for rechecking, so as to further improve the efficiency and accuracy of diagnosis of brucellosis.

Objective To evaluate the effect for the treatment of severe asthma. Methods The data of 47 patients with severe asthma who were admitted to emergency department were retrospectively anayzed. Results Of total 47 patients ,45 were rescued, with the survival rate of 95.7%. Arterial blood gas was improved after treatment (P < 0.01). Conclusion Appropriate commencement, mode, strategy, and early weaning of mechanical ventilation, combined with the administration of bronchodilators and eorticosteroids are the important way to rescue patients with severe asthma.

Objective To examine whether the increase of carbon monoxide (CO) induced by oral methylene chloride (MC) administration in recipients before heart transplantation would protect heart grafts against isehemia/reperfusion (I/R) injury associated with transplantation and to explore the possible mechanism.Methods Inbred male Balb/c mice were used as donors and recipients to establish cervical heart transplantation model Recipients were treated with either MC (100 mg/kg or 500 mg/kg,per os)(group MC 100 mg,n=10;group MC 500 mg,n=12) or olive oil(0.15 ml,per os.group olive,n=10) 3 h prior to anesthesia.Age-matched norwlal mice served as controls (group N,n=5).The serum COHb and the CO content of myocardial tissue were measured at 0,1,3,6,12,24 h after oral MC administration.Half of recipients were killed at 3 and 24h after transplantation for senum or cardiac graft samples.The serum cTnI levels,the mRNA levels of TNF-α,IL-10,Bcl-2,Bax.the protein levels of NF-κB and the ultrastructures of myocardium were examined.Results As tompared with group olive.the serum COHb and tissue CO were increased significantly and peaked within 3 h in group MC 100 mg and group MC 500 mg.The serum cTnI levels in group MC 100 mg and group MC 500 mg were significantly decreased (P<0. 01 ), especially in group MC 500 mg. The increase of CO in recipients of group MC100 mg and group MC 500 mg significantly inhibited the proinflammatory gene expression of TNF-α mRNA and the pro-apoptotic gene expression of Bax mRNA (P<0. 01), and increased the anti-apoptotic gene expression of Bcl-2 mRNA (P<0. 01), but did not increase the anti-inflammatory gene expression of IL-10 mRNA (P>0. 05) in the heart grafts. As compared with group N, the myocardial NF-κB activation was increased significantly in group olive,group MC 100 mg and group MC 500 mg (P<0. 01 ), but there was no significant difference among the later three groups (P>0. 05). The myocardial ultrastructure was also alleviated significantly in group MC 100 mg and group MC 500 mg as compared with group N. Conclusion The increase of CO induced by MC in recipients suppresses pro-inflammatory and pro-apoptotic gene expression and efficiently ameliorates transplant-induced heart I/R injury. The possible mechanism does not seem to be associated with down-regulation of the NF-κB signaling pathway.
