Objective To observe the influence of early intestinal barrier protection in patients with severe acute pancreatitis(SAP). Methods To analyze the therapeutic methods and prognosis of 56 patients with SAP. The patients were randomly divided into the conventional therapy group (A) and the intestinal barrier protection group (B). The APACHE Ⅱ score, Ranson score, Marshall score, CT severity index (CTSI), gastrointestinal functions score (GFS), the ratio of Lactulose to Mannitol (L/M), plasma Endotoxin and Diamine Oxidase (DAO), serum C-reactive protein (CRP) and TNF-α, incidence of pancreatic infection and multiorgan dysfunction syndrome (MODS), and the hospitalization mortality were compared between the two groups. Results On the 7th day after admission, the APACHE Ⅱ score, GFS, L/M, Endotoxin, DAO, CRP and TNF-α were significantly less in group B than in group A (P<0. 05). There was no significant difference in the CTSI (P>0. 05)between the two groups at 2nd week after admission. The incidence of pancreatic infection and MODS in group B were significantly lower than in group A (P<0. 05). The hospitalization mortality was not significantly different (P>0. 05) between the two groups. Conclusion Early intestinal barrier protection in SAP alleviated systemic inflammatory response, and reduced the incidences of pancreatic infection and MODS, thus improved the prognosis.

OBJECTIVETo assess the effect of repeated gonadotropic stimulations on the developmental potential and growth differentiation factor-9 (GDF-9) expression of mouse oocytes.

METHODSFemale Kunming mice were treated with pregnant mare serum gonadotropin (PMSG) and human chorionic gonadotropin (HCG) for 3 times, and the control mice were treated with normal saline. The two groups of mice were both stimulated subsequently to obtain the mature oocytes. Immunocytochemical staining was employed to evaluate GDF-9 expression in the oocytes. The oocytes were then inseminated and cultured till the formation of blastocysts to compare the cleavage rate and blastocyst formation rate between the groups.

RESULTSA total of 253 mature oocytes were obtained in the repeated stimulation group, with a mean of 11.5 oocytes from each mouse; 521 mature oocytes were obtained in the control group with a significantly greater mean number of 32.6 from each mouse (P<0.05). The average optical density and integrated optical density for GDF-9 expression were significantly lower in the oocytes in repeated stimulation group than in the control group (P<0.05 and 0.01, respectively). After insemination, the cleavage rate were comparable between repeated stimulation group and the control group (85.6% vs 88.8%), but the blastocyst formation rate was significantly lower in repeated stimulation group (20.8% vs 35.2%, P<0.01).

CONCLUSIONRepeated gonadal stimulation decreases the developmental potential of mouse oocytes possibly due to reduced GDF-9 expression.

Objective To investigate the predictive value of neutrophil to lymphocyte ratio (NLR) at admission for mortality risk during hospitalization in patients with acute ischemic stroke (AIS). Methods Patients with AIS admitted to the Department of Neurology, the First Affiliated Hospital of China Medical University from January 2017 to December 2018 were enrolled retrospectively. The demographic data and all baseline clinical data were collected, and compared between the in-hospital death group and survival group. Multivariate logistic regression analysis was used to determine independent influencing factors for in-hospital death in patients with AIS. The receiver operating characteristic (ROC) curve was used to evaluate the predictive value of NLR for death during hospitalization. Results A total of 266 patients with AIS were enrolled, with an average age of 65 years, 168 were males (63.2% ), 98 were females (36.8% ), 52 died in hospital (19.5% ), and 214 (80.5% ) survived. The NLR of the death group was significantly higher than that of the survival group (median [ interquartile range]: 7.6 [4.6-14.0] vs. 2.4 [1.8-4.0]; Z=7.727, P<0.001). Multivariate logistic regression analysis showed that advanced age (odds ratio [OR] 1.07, 95% confidence interval [CI] 1.01-1.14; P=0.009), previous history of stroke or transient ischemic attack (OR 9.06, 95% CI 2.06-39.88; P=0.004), high NIHSS score (OR 1.13, 95% CI 1.04-1.24; P=0.004), and high NLR (OR 1.23, 95% CI 1.02-1.48; P=0.024) were the independent risk factors for death during hospitalization in patients with AIS. ROC curve analysis showed that the area under the curve of NLR predicting death during hospitalization for patients with AIS was 0.846 (95% CI 0.786-0.905; P<0.001). When the cut-off value of NLR was 4.52, the sensitivity and specificity were 76.9% and 80.8% respectively. The positive predictive value was 49.4% , and the negative predictive value was 93.5% . Conclusions The increased NLR level at admission had certain predictive value for the death of patients with AIS during hospitalization.

Objective To investigate the correlation between serum lectin like oxidized low density lipoprotein receptor-1 ( sLOX-1 ) and left ventricular diastolic function in patients with essential hypertension. Methods From January 2016 to July 2017, one hundred and forty-six patients with essential hypertension were selected and divided into two groups according to the ratio of E/ A,the left ventricular diastolic function group (76 cases) and the left ventricular diastolic function group (70 cases),the sLOX-1 level of the patients was detected by ELISA method, and the left ventricular diastolic function was evaluated by echocardiography. The correlation between sLOX-1 and left ventricular diastolic function was analyzed. Results The serum sLOX-1 levels in left ventricular diastolic function group (( 208. 12 ± 13. 48 ) μg/ L ) were significantly higher than those inthe left ventricular diastolic function group ((152. 12 ± 12. 96) μg/ L) . The difference between the two groups was statistically significant (t= 6. 586,P= 0. 000). Logistic regression analysis showed that serum sLOX-1 was a influence factor of left ventricular diastolic function (OR= 2. 42,95%CI 1. 42-2. 82,P = 0. 036) . Conclusion The levels of serum sLOX-1 can be used as a indicator of left ventricular diastolic function.

OBJECTIVETo observe the therapeutic effects of acupuncture at Neiguan (PC 6) on silent myocardial ischemia (SMI).

METHODSForty patients with SMI were randomly divided into an electroacupuncture group and a medicine group, 20 cases in each group. The Electroacupuncture group was treated with electroacupuncture and Neiguan (PC 6) was selected as the main acupoint, and the other acupoints were selected by syndrome differentiation. The medicine group was treated with oral administration of compound Danshen dripping pill. The total effective rate, heart rate, blood pressure and dynamic electrocardiogram in 24 h were compared.

RESULTSThe total effective rate of 95.0% (19/20) in the electroacupuncture group was better than that of 75.0% (15/20) in the medicine group (P < 0.05). After treatment, the heart rate, systolic blood pressure and diastolic blood pressure in the two groups were decreased significantly (P < 0.01, P < 0.05) and the electroacupuncture group was superior to the medicine group (all P < 0.05). The SMI duration and the number of ST segment depression were decreased significantly in both groups after treatment (P < 0.01, P < 0.05) and the electroacupuncture group was superior to the medicine group (P < 0.05).

CONCLUSIONAcupuncture at Neiguan (PC 6) has a good therapeutic effect on SMI. It can decrease the heart rate and blood pressure, reduce the afterload in left ventricular and is superior to that of compound Danshen dripping pill.

OBJECTIVETo study the polymorphisms and secondary structure of human immunodeficiency virus (HIV-1) tat exon 1 among subtype B' and B'/C HIV-1 infected people in China and to explore the relationship between the polymorphism of tat exon 1 and the disease progression.

METHODS8 subtype B' and 5 B'/C HIV-1 infected patients with slow disease progression were selected from Liaoning, Jilin and Yunnan province. 26 subtype B' and 9 B'/C HIV-1 infected patients with similar sex, age but with typical disease progression were selected. Provirus was extracted from the whole blood. The gene sequences of the Tat exon 1 were amplified by nest-polymerase chain reaction (nest-PCR). Products were purified and sequenced directly. The sequences were aligned, translated, amino acid substitution were analyzed and secondary structures were predicted.

RESULTSMany amino acid substitution could be found in the exon 1 of Tat in HIV-1 subtype B' and B'/C recombinant strain infected persons with different disease progression except A58T,none of them showed definitely relationship with HIV viral load and disease progression. 23N, 31S, 32Y and 46F were subtype-specific substitutions. No characteristic secondary structure of exon 1 of Tat was found.

CONCLUSIONSome of the mutations of tat exon 1 might be related to HIV viral load and disease progression. However, there was no relationship found between the secondary structure of Tat protein and the disease progression.
