Objective To evaluate the virological and immune responses of Lopinavir/Ritonavir (LPV/r) based second-line regimen in elderly acquired immunodeficiency syndrome (AIDS) patients who failed first line regimens.Methods This was a retrospective cohort study.Elderly patients (≥50 years) who switched to LPV/r-based second-line antiretroviral therapy with human immuno-deficiency virus (HIV) RNA >1 000 copies/mL after more than 1 year of first-line treatment were recruited from Zhengzhou No.6 People Hospital from January 2010 to December 2011.The virological and immunological data during 60-month treatment were collected.Multivariate logistic regression was used to explore the risk factors associated with virological failure or immunological failure of 60-month second-line therapy.Results Totally 256 patients were enrolled with 109 male and 147 female.89.5% were plasma donator.The median age at the time of switching to LPV/r based second-line regimen was 61 years old.Twelve out of the 256 cases were detected for genotypic drug resistance and ten of them were resistant to drugs.No resistance to protease inhibitor (PI) was found.After switching to LPV/r based second-line regimen, HIV viral suppression (HIV RNA≤400 copies/mL) rates at 12, 24, 36, 48, 60 months were 69.5%, 78.4%, 79.0%, 79.7%, and 83.2%, respectively.The CD4+ T cell counts were (313±135) /mL at 12 months, (377±151) /mL at 24 months, (396±155) /mL at 36 months, (389±163) /mL at 48 months and (412±147) /mL at 60 months, which were all significantly higher than that at the initiation of therapy ([243±146] /mL,t=19.092,18.598,12.843,8.516 and 12.980, respectively;all P<0.05).After switching to LPV/r based second-line regimen for 60 months, 43 patients occurred virological failure and 48 patients occurred immunological failure.Multivariate logistic regression showed that poor adherence (OR=48.5, 95% CI: 15.9-98.4, P<0.01) and ART drug toxicity (OR=4.5, 95% CI: 2.6-11.3, P<0.01) were the main factors associated with virological failure at 60 months.Poor adherence (OR=15.1,95% CI: 6.89-33.3, P<0.01), CD4≤100 /mL at the time of switching therapy (OR=10.5,95% CI: 5.1-21.7, P<0.01), concomitant medications (OR=3.6,95% CI:1.6-4.1,P<0.01) were main factors associated with immunological failure at 60 months.Conclusions Elderly patients (≥50 years) who failed first line regimen should switch to LPV/r contained regimen as early as possible.Adherence education should be strengthened, drug toxicity as well as complications of treatment should be managed in time and concomitant medications should be reduced.

Breast cancer has overtaken lung cancer as the most common malignancy in women. Although the early diagnostic rate has continuously improved, recurrence and metastasis remain a problem to be solved. Therefore, scientists should search for effective prognostic markers for breast cancer patients and adopt individualized programs for different patients. Studies have shown that cancer prognosis, to a certain extent, is related to the nutrition inflammation index. Preoperative prognostic nutritional index (PNI) and controlled nutritional status (CONUT) are indicators that comprehensively reflect the nutritional level and inflammatory state of patients, respectively. Different from other cancers, the incidence of breast cancer is related to nutritional status, and an extremely high or low score is not conducive to the prognosis of breast cancer patients. This paper reviews the research progress of PNI and CONUT in breast cancer.

Vertebrobasilar dolichoectasia (VBD) as a distinct arterial disease is not rare.Posterior circulation cerebral infarction was one of the most frequent events and the primary cause of death in patients with VBD.The clinicoradiologic features and the pathophysiological mechanism of ischemic stroke in VBD remained unclear and required further investigation.We aimed to provide a review of advanced studies.

Objective To study the survival status and the prognostic factors of aquired immune deficiency syndrome (AIDS) patients under the highly active antiretroviral therapy (HAART) in He'nan Province.Methods Survival data of AIDS patients were collected from the National HAART reporting system between 2005 and 2015,and analyzed using SPSS 23.0 software.Results A total of 38 143 AIDS cases were enrolled in this study.The cumulative survival rate of patients under antiretroviral therapy after 1-5 years were 95％,91％,89％,86％ and 85％,respectively.The cumulative death cases were 5 704 and the total mortality was 3.68/100 person years (5 704/155 060 person years).A total of 1 975 cases died within a year with a percentage of 34.62％.Cox proportional hazard regression model analysis indicated that the hazard ratioc (HR [95％CI]) of death in patients with age of 40-49 years,50-59 yrears,60-69 yrears and ≥70 years groups compared to those with age ＜30 years group were 1.49 (1.22-1.80),1.88 (1.55-2.28),2.82 (2.32 3.42) and 4.60 (3.75-5.65),respectively.The HR (95％ CI) of death in patients with CD4 T cell counts ＜50 cells/μL,50-199 cells/μL,200-349 cells/μL groups compared to those of ≥350 cells/μL group were 3.28 (2.98-3.61),2.30 (2.09-2.53) and 1.39 (1.25-1.54),respectively.Male (HR-1.35,95％CI:1.28-1.42) and not switching to second line therapy (HR=4.41,95％CI:4.12-4.73) were the risk factors of death.Compared to sex transmission,blood transmission was the risk factors of death in AIDS patients.Conclusions The initiation of early HAART and timely switching to second line therapy for AIDS patients are key to prolong the survival time and to reduce AIDS related death.

Objective To discuss the epidemiology and clinical characteristics of AIDS in some part of Henan regions.Methods Retrospective analysis was conducted based on the clinical and epidemic information collected from AIDS patients who were treated in the Sixth People's Hospital of Zhengzhou between 2006 and 2015 in He'nan province.Results Between 2006 and 2015,the number of hospitalization increased every year.The average growth rate was 20.31％.The average age of patients was (43.91 ± 13.56) years old.The patients from 40 to 60 years old group occupied 54.06％ of total patients,and 71.12％ of patients were farmers.During 2006 to 2015,the propagation path changed a lot.Before 2008,blood transmission was the major propagation path (72.72％),but after 2013,the major propagation path was sexual activity (59.69％).40.41％ of patients were infected by two or more opportunistic infections.The top five opportunistic infections were bacterial pneumonia (32.68％),tuberculosis (19.29％),fungal infection (18.65％),pneumocystis carinii pneumonia (12.96％),extra pulmonary tuberculosis (7.45％).The death rate was 5.79％.The number of CD4 cells in peripheral blood was closely related to the severity of illness.Conclusion Early anti-virus treatment and opportunistic infection control are key factors to relieve the severity of illness and reduce the death rate.

Objectives To conduct a research on the possibility and effect factors of latent fingerprints development in clothing objects after vacuum coating, and extracting fingerprints DNA and to probe in the relation among DNA template quantity and genetic loci numbers tested, and the rfu value after coating. Methods To select two groups that are free sweat hands and sweat hands and have them press their fingerprints on the cloth, after coating, and to analyze the effect of time, to quantify and test the targeted fingerprints DNA, to compare the locus numbers tested between white and black cloth. Results As the time is prolonged, the locus numbers tested decrease. The locus numbers tested on the group of sweat hands using the same method after the same placed time are lager than the free sweat hands. When the value of rfu is 600 above, the ratio of the locus numbers tested is more than 90% and the threshold of templates is 0.013ng. The locus numbers tested of white cloth is larger, comparing with black cloth when using the same method. What is more, there exists an prohibitive influence of pigments of the dyed cloth over the PCR amplification, to put it further, the loci numbers tested will be trimmed. Conclusion The technology of vacuum coating can be well used in the area of detecting fingerprint DNA.

Objective:To investigate the application value of noninvasive prenatal DNA screening combined with nuchal translucency thickness measurement in the diagnosis of fetal chromosome aneuploidy.Methods:A total of 5 730 pregnant women who were screened for fetal chromosomal diseases in the Quzhou Maternal and Child Health Hospital from January 2017 to March 2019 were included in this study. All of them underwent noninvasive prenatal DNA screening and nuchal translucency thickness measurement. The results of amniocentesis were used as the gold standard to evaluate the diagnostic efficacy of noninvasive prenatal DNA screening, nuchal translucency thickness measurement and their combination.Results:Noninvasive prenatal DNA screening revealed that 64 (1.12%) women out of 5 730 pregnant women had high risk of developing chromosomal abnormalities. Ultrasound examination results showed that nuchal translucency was thickened in 140 (2.44%) women. The outcome of adverse pregnancy increased with the increase of nuchal translucency thickness. Among the 68 pregnant women who underwent amniocentesis, 51 women developed chromosomal abnormalities, with trisomy 21 syndrome being the majority (23/51,45.10%). The diagnostic efficacy of noninvasive prenatal DNA screening combined with nuchal translucency thickness measurement in the diagnosis of fetal chromosomal aneuploidy reached the ideal level.Conclusion:Noninvasive prenatal DNA screening combined with nuchal translucency thickness measurement has a high clinical application value. The combined method can be used as the main prenatal DNA screening method for pregnant women and it can effectively avoid the birth of children with chromosomal abnormalities.
