Objective:To evaluate the effect of prior statins use on the in-hospital mortality of adult sepsis patients with type 2 diabetes (T2DM).Methods:A total of 3 545 sepsis patients with T2DM were retrospectively collected from the Critical Care Medical Information Market (MIMIC Ⅳ) database, with in-hospital mortality rate as the outcome variable. According to whether they have taken statins in the past, they were divided into two groups and propensity score matching was used. Multivariate Cox regression analysis was performed to calculate the adjusted hazard ratio ( HR) and 95% CI, and the relationship between past statins use and in-hospital mortality in sepsis patients with T2DM was analyzed. Results:A total of 3 545 sepsis patients with T2DM were included between 2008 and 2016. 1 556 patients used statins before admission, and 1 989 patients did not use statins. After propensity score matching, the number of patients who had previously used statins and those who had not used statins were 1 230 and 1 298, respectively. After adjusting for potential confounding factors, it was found that previous use of statins was associated with a reduced in-hospital mortality rate ( HR=0.82, 95% CI: 0.61-0.99, P=0.038). Kaplan Meier curves showed that sepsis patients with T2DM who used statins before admission had a lower in-hospital mortality rate (Log rank test: P<0.001). Conclusions:Pre admission use of statins may be associated with a reduced mortality rate in sepsis patients with concomitant T2DM.

Objective To study the relationship between serum urine regulator protein and cystatin C levels and pathological characteristics and prognosis in patients with hypertensive nephropathy.Methods A total of 100 patients admitted in the hospital from August 2021 to October 2022 were selected as the study group,and 40 healthy persons who underwent the physical examination in the hospital were selected as the control group,complete data of all patients were collected and analyzed,the levels of serum urinary regulatory protein and cystatin C in each group were tested,and the relationship between serum urinary regulatory protein and cysta-tin C levels,pathological characteristics,and prognosis was analyzed.Results The urine regulatory protein and glomerular filtration rate in the study group were lower than those in the control group,but cystatin C,u-rea nitrogen,and blood creatinine were all higher than those in the control group,and the differences were sta-tistically significant(P＜0.05).Urinary regulatory protein was negatively correlated with urea nitrogen and blood creatinine,but positively correlated with glomerular filtration rate(P＜0.05).Cystatin C was positively correlated with urea nitrogen and blood creatinine,but negatively correlated with glomerular filtration rate(P＜0.05).Urinary regulatory protein level was related to crescent formation,renal tubular atrophy/intersti-tial fibrosis(P＜0.05),while level the expression of cystatin C was related to glomerular segmental sclerosis,glomerular glomerular sclerosis,and glomerular ischemic shrinkage(P＜0.05).The survival rate of the high urinary regulatory protein level group(≥126.49 ng/mL)was higher than that of the low urinary regulatory protein level group(＜126.49 ng/mL),while the survival rate of the high cystatin C level group(≥2.43 mg/L)was lower than that of the low cystatin C level group(＜2.43 mg/L)(P＜0.05).Urinary regulatory protein,cystatin C,renal tubular atrophy/interstitial fibrosis were factors that affected the occurrence of end-stage renal disease in hypertensive nephropathy(P＜0.05).Conclusion Hypertensive kidney disease patients u-sually have higher levels of cystatin C and lower levels of urinary regulatory protein,among which cystatin C is closely related to pathological features of glomerular segmental sclerosis,glomerular glomerular sclerosis,and glomerular is-chemic shrinkage,and urinary regulatory protein is closely related to crescent formation,renal tubular atrophy/intersti-tial fibrosis.In addition,urinary regulatory protein and cystatin C have a significant impact on the development of hy-pertensive nephropathy into end-stage renal disease,and could become important indicators for evaluating patient prognosis.

Objective:To study the effects of poly adenosine diphosphate ribose polymerase (PARP) inhibitors niraparib and pamiparib on the radiosensitivity of breast cancer cell lines MCF-7 and MDA-MB-436, and to explore its mechanism.Methods:MCF-7 and MDA-MB-436 cells were divided into control group, niraparib group, pamiparib group, radiation group, combination group treated with niraparib and radiation, and combination group treated with pamiparib and radiation, respectively. The effects of drugs on cell proliferation and radiosensitivity were measured by CCK-8 assay and colony formation assay, respectively. The effect of drugs combined with radiation on cell cycle and apoptosis were detected by flow cytometry. Immunofluorescence method was used to detect the changes of γ-H2AX focal number of cells. The expressions of FANCG, Bax and Bcl-2 mRNA and protein were detected by qPCR and Western blot, respectively.Results:Both niraparib and pamiparib inhibited the proliferation of breast cancer cells MCF-7 and MDA-MB-436 in a time-dose dependent manner. With the increase of irradiation dose, D0, Dq, SF2 value of MCF-7 and MDA-MB-436 cells decreased, and SER D0 and SER Dq value increased. Compared with control group, the percentages of cells in G 2/M phase were increased ( tMCF-7=41.66, 44.08, P<0.05; t436=24.69, 18.91, P<0.05), the percentage of cells in G 0/G 1 phase were decreased ( tMCF-7=8.67, 29.61, P<0.05; t436=26.39, 29.12, P<0.05), and the cell apoptosis rate was significantly increased ( tMCF-7=11.17, 11.71, P<0.05; t436=42.68, 15.89, P<0.05) in the combination group. Compared with control group, the number of γ-H2AX foci of MCF-7 cells in the radiation group and combination group treated with niraparib and radiation increased significantly at 2 h after irradiation ( t=8.89, 21.72, P<0.05). At 24 h after irradiation, the number of γ-H2AX foci basically returned to normal level in the radiation group but remained at a higher level in the combination group ( t=8.82, P<0.05). Compared with control group, the expressions of FANCG and Bcl-2 mRNA decreased ( tFANCG=14.07, P<0.05; tBcl-2=29.21, P<0.05), the expression of Bax mRNA increased ( t=8.90, P<0.05), and the expression of FANCG and Bcl-2 proteins decreased ( tFANCG=7.09, P<0.05; tBcl-2=10.24, P<0.05), while the expression of Bax protein increased ( t=2.90, P<0.05) in the combination group. Conclusions:PARP inhibitors niraparib and pamiparib can increase the radiosensitivity of breast cancer MCF-7 and MDA-MB-436 cells probably through down-regulating the expression of FANCG in FA-BRCA pathway, up-regulating apoptosis-related genes and inhibiting DNA damage repair.

Objective To establish a druggability evaluation method for new targets of anti-tumor drugs by analyzing the mutation genes of common tumors in the digestive system. Methods We collected the mutant gene data of the five common tumors of the digestive system (esophageal cancer, gastric cancer, colorectal cancer, liver cancer and pancreatic cancer) in the Integrative Onco Genomics database, and screened out the genes with higher mutation rates in each tumor. We evaluated the druggability of these genes or their encoded proteins, and discovered the potential targets for the new anti-tumor drugs. Results A total of five tumors, 35 cohorts and 5445 tumor samples were collected in this study. The top 10 mutation genes were selected for further analysis. The canSAR database was used to analyze the druggability of unpublished mutant genes or their encoded proteins, and a total of 17 potential therapeutic drug targets were screened out. Conclusion A method for evaluating druggability of targets based on mutant genes or their encoded protein is established in this study. The application of this method can provide a reference for discovering new anti-tumor therapeutic target, saving the cost and time of target screening in new drug development.

Objective: To clarify the genotype of varicella-zoster virus (VZV) in Jilin province in 2017, and to discriminate between vaccine strain and wild-type strain. Methods: Vesicle fluid and throat swab samples were collected from 10 individuals with suspected VZV in Jilin province from January to March of 2017. Real-time fluorescent quantitative PCR was used to detect viral nucleic acid. Specific regions of ORF22, ORF38 and ORF62 of VZV were amplified by PCR. Viral genotype was determined by five SNPs of ORF 22 and vaccine strain or wild-type strain was distinguished by four SNPs of ORF 38 and ORF 62. The results were analyzed with MEGA5 and BioEdit software, using the VZV reference strain sequences from GenBank. Results: VZV-positive strains were detected in 10 samples, all belonged to Clade 2. There was a synonymous mutation (C→T) in position 38 048 of JL17-7 strain. The nucleotide homology of ORF22 showed that all 10 samples were on the same branch with the Clade 2 referenced strains. Compared with Clade 2 referenced strains, the homology of nucleotide and amino acid for all 10 samples were 99.5%-100% and 99.3%-100%, respectively. The four specific SNPs of ORF38 and ORF62 in 10 samples were A-T-T-T, which were consistent with wild-type strain. Conclusions This study reveals that the VZV strains circulating in Jilin province in 2017 were all wild-type strains belonging to Clade 2.

OBJECTIVE:To observe therapeutic efficacy and safety of NB-UVB combined with Total glucosides of white paeony(TGP)capsules and Urea cream in the treatment of psoriasis vulgaris. METHODS:A total of 75 patients with psoriasis vulgaris in dermatology department of our hospital during Jan. 2015-Dec. 2016 were divided into control group(37 cases)and observation group(38 cases)according to random number table. Control group was given TGP capsules 0.6 g orally,3 times a day,reducing to 0.3 g,3 times a day if diarrhea or stool increased significantly after taking the medicine+Urea cream,smearing on the skin,day and evening,for consecutive 12 weeks. Observation group was additionally given NB-UVB irradiation with initial dose of 0.36 J/cm2,2 min/time,every other day,adjusted according to skin reaction for consecutive 8 weeks,on the basis of control group. Clinical efficacies of 2 groups were observed,and PASI scores before and after treatment and the occurrence of ADR were observed. RESULTS:One patient of observation group withdrew from therapy after suffering from obvious edematous erythema with pain due to irradiation. All patients of control group completed treatment. Total response rate of observation group (86.49%)was significantly higher than that of control group(56.76%),with statistical significance(P<0.05). Before treatment, there was no statistical significance in PASI scores between 2 groups(P>0.05). After treatment,PASI scores of 2 groups were significantly lower than before treatment,and observation group was significantly lower than control group,with statistical significance(P<0.05). There was no statistical significance in total incidence of ADR between 2 groups(P>0.05). CONCLUSIONS:NB-UVB combined with TGP capsules and Urea cream show good therapeutic efficacy and safety for psoriasis vulgaris,and can significantly decrease PASI score of patients.

Contracture and spasticity of ankle joints were major sources of disability in neurological impairment including stroke and cerebral palsy, etc. The manual stretching used in physical therapy might be laborious and time-consuming to the therapists and the outcome was dependent on the experience and the subjectiveend feelingof the therapists. A device was developed that could safely stretch the an-kle joint to its extreme positions with quantitative control of the resistance torque and stretching velocity. Furthermore, it could satisfy a strong need for quantitative and objective measures of the impairment and rehabilitation outcome. This was just the meaning intelligent stretching referred to. This article described the origin of the concept of intelligent stretching and its definition, operational principle, and su-periority and weakness, as well as its application in ankle joint spasticity and contracture in patients with stroke and cerebral palsy.
