Objective:To research the application of flurbiprofen compound small dose fentanyl with self-control vein analgesia after laparoscopic cholecystectomy and the influence on blood coagulation function.Methods:102 cases with laparoscopic cholecystectomy who were treated in our hospital from November 2015 to November 2016 were selected and divided into the control group and the research group,with 51 cases in each group.The patients in the control group were treated with postoperative intravenous analgesia with low-dose fentanyl,while the patients in the research group were treated with postoperative intravenous analgesia with flurbiprofen ester compound low-dose fentanyl.Then the fibrinogen (Fg),activated partial prothrombin time (APTT),prothrombin time (PT),platelet count (PLT),substance P,5-hydrocarbon serotonin (5-HT),interleukin 6,8 (IL-6,IL-8) and complications between two groups were observed and compared.Results:Before treatment,there was no statistically significant difference about the Fg,APTT,PT,PLT,substance P,5-HT,IL-6 and IL-8 between two groups (P＞0.05);After treatment,the Fg,APTT,PT,PLT,substance P,5-HT,IL-6 and IL-8 increased in the two groups,while the research group was lower than that of the control group,and the differences were statistically significant (P＜0.05).The postoperative complication rate of research group was lower than that of the control group (P＜0.05).Conclusion:Flurbiprofen ester compound small dose fentanyl with self-control vein analgesia can relieve coagulation function,and inhibit the levels of inflammatory factors.

Objective To study the preoperative treatment and prognosis observation? in sensitized recipients of kidney transplantation.Method Forty-one recipients positive for preoperative PRA accepted renal allograft transplantation from January 2007 to July 2012.All recipients were given immunosuppressant or immune induction by anti-CD25rnAb in advance,and plasma exchange,immunoadsorption and intravenous high-dose immune globulin were administered.Meanwhile,donor HLA antigens had to avoid all stored HLA antibodies of the recipient,and lymphocyte cytotoxicity cross test (CDC) had to be negative.Anti-human lymphocyte globulin (ATG) was used to strengthen the immune induction,and tacrolimus + mycophenolate mofetil (MMF) + corticosteroids triple immunosuppressive regimen was adopted after transplantation.Then intravenous micafungin would be given after transplanted kidney function was normal,and ganciclovir and sulfamethoxazole were taken orally to prevent infection.Result In 41 recipients positive for preoperative PRA,13 cases were positive for only HLA class Ⅰ antibodies,15 cases for only HLA class Ⅱ antibodies,and there existed 13 cases of both HLA class Ⅰ and class Ⅱ antibodies also with PRA≥50％.Fifteen patients achieved normal serum creatinine in one week,and no hyperacute rejection and accelerated rejection occurred.Fourteen recipients experienced an episode of acute rejection (34.15％,14/41): 12 recovered by steroids bolus therapy,and the other two reversed in 3-5 days by cyclophosphamide or ATG treatment.One case died of mycotic pneumonia in 4 months later.One-year recipient/kidney survival rate was 97.6％ (40/41).Conclusion The recipients positive for preoperative PRA only can accept renal allograft transplant while the donor's HLA antigens had to avoid all stored HLA antibodies of recipients themselves and CDC test was negative.After that the combination of desensitization therapy,immune induction therapy and postoperative potent immunosuppressant can prevent acute rejection effectively and increase postoperative recipient/kidney survival rate.

Objective To investigate a possible association of donor-recipient compatibility for ABO blood group alleles with acute rejection (AR) in renal transplantation. Methods A study comprising 87 pairs of donor and recipient was performed. The ABO genotype A1, A2, O1, O2, and B alleles of renal transplanted recipients and their respective donors were assessed by PCR amplification with sequence-specific primers (PCR-SSP). Accordingly, recipients were divided into donor-recipient ABO genotype matched and mismatched groups. Results The PCR-SSP based types of all cases showed total concordance with their serologically assigned ABO groups. Fifty pairs (57. 5%) were matched for ABO genotype among the 87 pairs of donor and recipient while 37 (42. 5%) were mismatched, including 1 allele mismatch in 31 pairs (83.8%), 2 alleles mismatches in 6 pairs (16. 2%).The incidence of AR was 12.0% (6 cases) and 29. 7% (11 cases) for ABO genotype matched and mismatched transplant patients, respectively ( P ＜ 0.05). After high dose methylprednisolone (MP)treatment, all cases exepienced reversion of AR except a A2O1 recipient receiving kidney from a A1O1enced 4 AR episodes within 3-10 months, and the period of AR was gradually shortened. After high dose MP was administered empirically, even though short-term improvement of renal function was observed, the serum creatinine continued to increase progressively with decreased efficacy of high dose MP. One year after operation the serum creatinine rose to 441 μmol/L. Conclusions Simultaneous definition of the ABO genotype and HLA is highly feasible. The A2 patient is suitable for receiving kidneys from blood group O donors. DNA mismatch for ABO genotype of renal transplant recipients and their respective donors is an independent risk factor for AR. Genotyping of ABO blood group is conducive to prevent AR.

Objective To explore the relationship of serum anti-MICA antibody and development of chronic rejection (CR) after renal transplantation. Methods The enrolled 105 patients included 43 cases of CR, and 62 cases of functioning renal allograft as controls. Data including PRA level before transplantation, HLA mismatch, cold ischemic time, SCr at discharge, immunosuppressive regimen,and months after transplantation were analyzed. Blood samples were collected immediately after grouping for anti-MICA antibodies, SCr determination. Acute rejection episodes and renal allograft function which was evaluated by △SCr/M [(SCr at present - SCr at discharge) /months after transplantation) were compared between anti-MICA-antibody positive patients and anti-MICA-antibody negative patients. Results There was no significant difference in gender, age, HLA mismatch, cold ischemic time, immunosuppressive regimen, SCr at discharge, months after transplantation between CR and control groups (P＞0.05). Serum creatinine level and number of antiMICA-antibody positive patients in CR group were significantly increased as compared with those in control group (P＜0.01 ). Acute rejection episodes during the first 3 months after transplantation in anti-MICA-antibody positive patients were significantly more than those in anti-MICA-antibody negative patients (P＜0.05),and the △SCr/M in the former was higher than that in the latter (8.3 +3.6 vs 2.4 ± 2.6, P＜0.05). Conclusion Humoral immunoreaction mediated by MICA partly participates the development of CR after renal transplantation. MICA antibody is a risk factor affecting long-term allograft function.

Objective: To investigate the self-monitoring blood pressure behavior and its influencing factors among residents in Jiangsu Province, so as to provide the basis for strengthening proactive blood pressure monitoring among residents. Methods: Permanent residents aged 35-75 years in six counties (cities, districts), Jiangsu Province, were selected using the stratified cluster sampling method in 2023. Data on basic information, disease history, and self-monitoring blood pressure behavior were collected, height and weight were measured to calculate the body mass index (BMI); and blood glucose and lipid levels were measured. Self-monitoring blood pressure behavior was defined as having measured blood pressure at least once in the past three months. Factors affecting self-monitoring blood pressure behavior were identified using a multivariable logistic regression model. Results: A total of 12 475 residents were surveyed, including 5 748 males and 6 727 females, with a male-to-female ratio of 1∶1.17. There were 3 855 residents aged 45-<55 years (30.90%) and 5 511 residents who had self-monitoring blood pressure behaviors (44.18%). Multivariable logistic regression analysis showed that the residents who were males (OR=1.167, 95%CI: 1.081-1.261), lived in rural areas (OR=1.430, 95%CI: 1.321-1.547), aged 45-75 years (45-<55 years, OR=1.384, 95%CI: 1.241-1.543; 55-<65 years, OR=1.397, 95%CI: 1.243-1.570; 65-75 years, OR=1.196, 95%CI: 1.049-1.363), had an annual household income ≥30 000 yuan (30 000-<60 000 yuan, OR=1.190, 95%CI: 1.072-1.321; 60 000-<110 000 yuan, OR=1.330, 95%CI: 1.191-1.485; ≥110 000 yuan, OR=1.746, 95%CI: 1.536-1.984), were overweight (OR=1.170, 95%CI: 1.070-1.280) or obese (OR=1.248, 95%CI: 1.120-1.391), were unaware (OR=1.221, 95%CI: 1.103-1.353) or aware (OR=3.937, 95%CI: 3.575-4.335) of having hypertension, were aware of having diabetes (OR=1.538, 95%CI: 1.354-1.749), and aware of having dyslipidemia (OR=1.265, 95%CI: 1.106-1.447) were more likely to have self-monitoring blood pressure behaviors. Conclusions Among the residents aged 35-75 years in Jiangsu Province, 44.18% had self-monitoring blood pressure behavior. Gender, place of residence, age, annual household income, BMI, hypertension, diabetes, and dyslipidemia were identified as influencing factors for self-monitoring blood pressure behavior.

Objective:To explore the effect of neutrophil-lymphocyte ratio (NLR) at the initial visit on the survival of children with newly diagnosed medulloblastoma (MB).Methods:This was a case-control study involving 61 children with newly diagnosed MB at the Department of Pediatrics, Beijing Shijitan Hospital, Capital Medical University from August 2018 to January 2020 .The blood cell counts, lymphocyte subsets and immunoglobulin in the periphe-ral blood were measured to calculate NLR at the initial visit.Based on the cut-off value determined by receiver opera-ting characteristic (ROC) curve, patients were divided into high NLR group (≥ 2.07, n=21) and low NLR group (<2.07, n=40). The progression-free survival (PFS) and overall survival (OS) between 2 groups were analyzed by the Kaplan-Meier method, followed by Log- rank test.The correlation between NLR at the initial visit with clinical characteristics, lymphocyte subsets and immunoglobulin of children with newly diagnosed MB was analyzed.Differences between groups were compared by the Chi- square test, Mann- Whitney U test and independent sample t test. Results:The survival analysis showed that the relapse rate (38.1% vs.10.0%, χ2=6.879, P=0.016) and mortality rate (19.0% vs.0, χ2=8.154, P=0.011) were significantly higher in high NLR group than those of low NLR group.PFS (12 months vs.19 months, χ2=9.775, P=0.002) and OS (19 months vs.20 months, χ2=8.432, P=0.004) were significantly shorter in high NLR group than those of low NLR group.No significant differences in clinical characteristics were detected between groups (all P>0.05). Compared with low NLR group, the percentage of T lymphocyte[(67.93±6.37)% vs.(73.38±8.08)%, t=2.886, df=48.865, P=0.006], T helper cells (Th)[(30.86±5.53)% vs.(34.29±7.44)%, t=2.037, df=51.981, P=0.047], and T suppressor cells (Ts)[(27.39±5.50)% vs.(30.84±6.58)%, t=2.164, df=47.581, P=0.035] were significantly lower in high NLR group.Spearman correlation analysis showed a negative correlation between NLR and T lymphocyte count ( r=-0.303, P=0.018), and Ts lymphocyte count ( r=-0.260, P=0.043). Conclusions:Children with newly diagnosed MB expressing a high level of NLR had a poor prognosis, which may be associated with T lymphocyte and Ts lymphocyte.

Chinese hamster ovary (CHO) cells play an irreplaceable role in biopharmaceuticals because the cells can be adapted to grow in suspension cultures and are capable of producing high quality biologics exhibiting human-like post-translational modifications. However, gene expression regulation such as transgene silencing and epigenetic modifications may reduce the recombinant protein production due to the decrease of expression stability of CHO cells. This paper summarized the role of epigenetic modifications in CHO cells, including DNA methylation, histone modification and miRNA, as well as their effects on gene expression regulation.
