Objective: To examine the impacts of chemotherapy/radiotherapy, targeted therapy, and combined treatment on the quality of life in patients with intermediate and advanced lung cancer. Methods: The patients with intermediate and advanced lung cancer undergoing chemotherapy/radiotherapy, targeted therapy, and combined treatment for the first time were recruited from a tertiary hospital in Weifang City, Shandong Province, using a quota sampling method in September 2023. Basic information was collected using a general information questionnaire, and the quality of life was assessed using the Chinese version of Functional Assessment of Cancer Therapy-General. The investigation started on the 7th day of treatment, and the follow-ups were conducted at 3 and 6 months. The quality of life in patients with different treatment regimens and at different treatment time were compared using repeated measure analysis of variance. Results: There were 26 chemotherapy/radiotherapy patients, 32 targeted therapy patients, and 95 combination therapy patients. There were no significant differences in age, gender, place of residence, education level, self-rated economic status, medical insurance, pathological type and disease stage among the three treatment regimens (all P>0.05). The repeated measure analysis of variance showed an interaction effect between time and group among patients receiving the three treatment regimens (P<0.05). The quality of life scores of patients receiving combination therapy decreased with extended treatment time (all P<0.05). The quality of life scores of patients receiving targeted therapy at 3 and 6 months were lower than those treated for 7 days (both P<0.05). No significant differences were observed in quality of life scores among chemotherapy/radiotherapy patients with different treatment durations (all P>0.05). At 3 and 6 months, patients receiving combination therapy had lower quality of life scores compared to those receiving chemotherapy/radiotherapy or targeted therapy (all P<0.05). Conclusion The decline in quality of life for patients with intermediate and advanced lung cancer undergoing chemotherapy/radiotherapy and targeted therapy is less than that for patients receiving combined therapy.

Objective To evaluate the effect of head-mounted virtual reality display on the visual function of adult myopia.Methods Thirty-four myopia patients were divided into two groups by random number table method:test group(n=18)and control group(n=16).After routine eye examination of the subjects,the naked vision,corrected vision,dynamic stereopsis,near stereopsis,contrast sensitivity,assemble value,disperse value,positive relative accommodation(PRA),negative relative accommodation(NRA),flexibility of accommodation,and amplitude of accommodation(AMP)before the test,after the test 1 time and after the test 10 times;the visual fatigue questionnaire score and the visual work ability answer score were performed before the test and after the test 10 times.Results There was significantly statistically significant of naked eye vision in test group after the test 10 times compared with the pre-test and the control group(P were 0.040,0.011);There was significantly statistically significant in assemble value of the test group after the test 10 times compared with the pre-test and the control group(P were 0.036,0.010);there were significantly statistically signifi-cant in the NRA and adjustment flexibility of the test group compared with the pre-test and the control after after the test 10 times(P were＜0.0001,＜0.0001,0.008,0.017);there were not statistical differences in corrected visual acuity,contrast sensitivity,spread value,dynamic stereopsis,near stereopsis,PRA,AMP,visual fatigue questionnaire scores and visual work ability were not statistically significant in comparison between the control group and the test group on the corresponding time points(P＞0.05).Conclusion This is helpful to improve some of the visual function parameters of myopia patients appropriate using of head-mounted virtual reality technology training such as naked vision,NRA,insufficient collection,and flexibility of adjustment.

Objective:To investigate the urinary virology and clinical characteristics of female overactive bladder (OAB) patients.Methods:Catheterized urine samples were collected from 55 women with OAB and 18 control individuals between January 2021 and August 2021. Inclusion criteria were: female with age>18, diagnosed as OAB, OABSS total score≥3 and item Urgency score≥2, informed consent signed. Exclusion criteria were: Urine culture positive, urinary catheter indwelling status, antibiotic usage in recent 30 days, other disease leading to OAB-like symptoms, pelvic organ prolapse and current pregnancy, immunosuppressive therapy or status. Clinical characteristic and history were collected. OAB symptoms were assessed via both OABSS (overactive bladder symptom score) and OAB-V8 (8-item overactive bladder questionnaire). The urine specimens were analyzed using mNGS for identifying viral infections. The correlation between the disease and JC virus infection was analyzed by t test, chi-square test, binary logistic regression analysis and Spearman correlation matrix, and the Nomogram map for predicting the risk of viral infection was constructed. Results:In total, 55 women with OAB and 18 healthy controls were recruited in the study. There are significant difference in terms of UTI history, pelvic surgery history and the habit of holding urine [60.0%(n=33)to 16.7%(n=3), P=0.002; 43.6%(n=24)to 0.0%(n=0), P<0.01; 36.4%( n=20)to 5.6%( n=1), P=0.015]. Based on mNGS results, OAB patients were identified with more positive viral infection [47.3%(n=26)to 33.3%(n=6)] and more JC virus infection. In the OAB group, subtype 7B of JCV ( n=8) was identified, while in the control group, subtype 7A(n=2) was identified. Pairwise Spearman correlation analysis indicated high correlations between viral infection and OABSS ( r=0.58), age and pausimenia ( r=0.68), hypertension and age ( r=0.53), respectively. Estimates from binary logistic regression model indicated risk factors for virus infection in OAB patients including age ( OR=1.99, 95% CI 0.02-2.61), holding urine habit( OR=2.16, 95% CI 0.18-3.85) and pelvic surgery ( OR=2.53, 95% CI 0.54-4.27). Conclusions:Urinary viral infections appear to be associated with more severe OAB symptoms and JC virus may be a potential therapeutic target for OAB.

Objective: To understand the social psychological status of the elderly in different age groups ( young, middle-aged and old) , and explore the main factors that influence the social psychological status of the elderly. Method:Using the Chinese Health and Retirement Survey ( CHARLS) database, the descriptive statistics, factor analysis and multiple linear regression were used to analyze the social psychological status and influencing factors of the elderly at different ages over 60 years of age in China. Results:The social psychological status of the elderly gradually became worse with age. The social psychological status of the elderly in the low age group was better than that in the middle age and the high age group; the depression factor of the middle age group was better than that of the low age group and the high age group;and the social psychological status of the elderly was generally poor. In the regression analysis, the effects of age, marital status, physical health status, activity frequency, and life satisfaction on the social psychological status of the elderly had statistical significance ( P <0. 05). Conclusion: Age, marital status, physical health status, activity frequency and life satisfaction are the main factors that influence the social psychological status of the elderly, and the government, society and relatives should pay attention to the social psychological health of the elderly.

Objective To explore the impact of cardio cerebral vascular diseases (CVD) on life expectancy among residents in Shandong Province,develop effective preventive measures for the high-risk population and provide guidance for the health care resource allocation.Methods Based on the death monitoring data of the disease in Shandong Province in 2012,we calculated the crude mortality and standardized the mortality rate of the disease.We designed life tables with all causes of death and with eliminating causes of CVD death and analysed life expectancy with and without them examined.Results In 2012,crude mortality rate of CVD was 320.16/100 000 (SMR 252.85/100 000) in Shandong Province.The death rate of CVD was of 46.30％ of all deaths reported by monitoring system.The mortality rate of CVD in male and female were 332.99/100 000 and 307.02/100 000,respectively.The mortality rate of CVD in rural and urban areas were 341.84/100 000 and 267.28/100 000,respectively.The mortality of CVD increased with age and growed rapidly after the age of 60.Life expectancy of urban and rural areas was 79.20 years and 78.14 years,respectively.After eliminating causes of CVD death,life expectancy for eliminating causes of CVD death in urban and rural areas increased 8.51 years and 10.02 years,respectively.Life expectancy for eliminating causes of CVD death in male and female increased 8.02 years and 11.10 years,respectively.Conclusions Life expectancy of urban and rural areas,the male and female for eliminating causes of CVD death than that of all causes of death were greatly extended.Reducing the death caused by CVD to increase health life expectancy have important public health significance.

Objective To evaluate the effect of conversion from mycophenolic acid (MPA) to mizoribine (MZR) in renal transplant recipients with gastrointestinal tract (GI) symptoms.Methods A total of 355 renal transplant recipients with GI symptoms caused by MPA administration were enrolled from April 2015 to March 2017 in 25 different renal transplant centers in China.The symptomatic improvement of GI before (baseline) and after conversion to MZR (1,2,4 weeks) was assessed by each item of GI symptoms indication.In addition,the efficacy and safety of the conversion therapy during 12 months were determined.Results Patients showed improvement in GI symptoms including diarrhea,abdominal pain,abdominal distention and stomachache after conversion to MZR 1,2,4 weeks (P＜0.05).In patients with different severity of diarrhea,conversion to MZR therapy significantly improved diarrhea (P＜0.05).During 12 months,no patient experienced clinical immune rejection.We did not observe any infections,leucopenia and other serious side effects.Conclusion MZR could markedly improve GI symptoms caused by MPA administration in renal transplant recipients.

BACKGROUND:Cytotoxic T lymphocyte-associated antigen 4 is a newly discovered costimulatory molecule. It has been studied more in tumor and autoimmune diseases, less in the field of kidney transplantation.
OBJECTIVE:To explore the role of cytotoxic T lymphocyte-associated antigen 4 in acute rejection after renal transplantation.
METHODS:Fifty patients undergoing renal transplantation were divided into acute rejection group (20 cases) and stable graft function group (30 cases). Another 30 healthy persons served as control group. Blood samples were extracted from the peripheral blood. Cytotoxic T lymphocyte-associated antigen 4 was detected by enzyme linked immunosorbent assay and flow cytometry.
RESULTS AND CONCLUSION:The expression of cytotoxic T lymphocyte-associated antigen 4 in the serum showed significant differences in the acute rejection group, stable graft function group and healthy control group (F=70.008 1, P=0.000 0), but showed no difference in peripheral blood lymphocytes of three groups (F=1.865 6, P=0.161 7). Compared with the healthy control group, the expression levels of cytotoxic T lymphocyte-associated antigen 4 in peripheral blood lymphocytes of acute rejection group and stable graft function group were significantly decreased (P=0.000 0). In addition, the acute rejection group had a lower cytotoxic T lymphocyte-associated antigen 4 expression than the stable graft function group (P=0.000 0). In renal transplant rejection, the expression of cytotoxic T lymphocyte-associated antigen 4 in serum was reduced, showing some correlation with acute rejection after renal transplnatation. Cytotoxic T lymphocyte-associated antigen 4 might be involved in the rejection.

Objective To investigate the effect of CYP3A5 * 3 and MDR1C3435T polymorphisms on the blood trough concentration of sirolimus in the Chinese renal transplantation recipients with stable renal function and the influencing factors for individual differences.Method 112 cases of Chinese renal transplantation recipients with stable renal function were recruited in this study.Related data of the recipients,including gender,age,height and body mass,were recoded.CYP3A5 and MDR1 genotypes were determined by the direct sequencing.Blood trough concentration of sirolimus was measured by using chemiluminescence microparticle immuno assay (CMIA).The influencing factors of individual differences in sirolimus blood trough concentration was analyzed,and the correlation of CYP3A5 * 3 and MDR1C3435T gene polymorphisms with sirolimus blood trough concentration was evaluated.Result Of the 112 cases,there were 10 cases (8.93％) of CYP3A5 * 1/* 1,49 cases (43.75％) of CYP3A5 * 1/* 3,and 53 cases (47.32％) of CYP3A5 * 3/* 3.Allele frequencies of CYP3A5 * 1 and * 3 were 30.81％ and 69.19％,respectively.There were 31 recipients (27.68％) with MDR1 3435CC,60 (53.57％) with MDR1 3435CT,and 21 (18.75％) with MDR1 3435TT.Allele frequencies for C and T at position 3435 of MDR1 were 54.46％ and 45.54％,respectively.In this study,recipients' CYP3A5 * 3 genotype was the main factor (P =0.000) of sirolimus blood trough concentration,but dose,gender,age,height,postoperative time,the level of serum creatinine,hemoglobin levels,combined use of CsA and MDR1C3435T genotype had no effects on sirolimus blood trough concentration (P ＞ 0.05).sirolimus blood trough concentration/(dose weight) in * 1/* 1,* 1/* 3 and * 3/* 3 recipients was (0.0721 ± 0.0202),(0.1055 ± 0.0395),and (0.1395 ± 0.0537) μg·L-1 ·mg-1 ·kg-1,respectively,The sirolimus blood trough concentration/ (dose weight) in * 1/* 3 recipients was 1.46 times higher than that in * 1/* 1 recipients,and that in * 3/* 3 recipients were 1.93 times higher than that in * 1/* 1 recipients.There was significant difference in sirolimus blood trough concentration/(dose weight) between recipients with different CYP3A5 * 3 genotypes (P =0.000).Conclusion The CYP3A5 * 3 gene polymorphism is closely related to the blood trough concentration/dose of sirolimus,and is the main factor of the blood trough concentration of sirolimus between individuals.

ObjectiveTo evaluate the efficacy and safety of HC-A Ⅱsolution in kidney preservation.Methods A multicenter,randomized,double-blind and controlled clinical trial was conducted.Between Jan.2008 and Dec.2010,kidney recipients from 9 transplant centers were randomly divided into two groups.Grafts in each group were perfused and stored in HC-A Ⅱ or HTK solutions respectively.Results277 patients were included in the Full Analysis Set (FAS),137 of whom were inHC-A Ⅱgroup and 140inHTK group. Demographic andbaseline medical characteristics were similar between the two groups.262 patients were included in the Per Protocol Set (PPS),133 of whom were in HC-A Ⅱ group and129 in HTK group.The percentages of patients with a serum creatinine level that returned to normal within 28 days postoperation were 86.9％ in HC-A Ⅱ group and 85.0％ in HTK group respectively (P＞0.05 ).The results from PPS analysis were consistent with those from FAS analysis The incidence of test-related adverse events was 2.9％ in HC-AⅡ group and 0.7％ in HTK group respectively (P＞0.05).No test-related serious adverse events occurred throughout the study.ConclusionHC-A Ⅱ solution,the same as HTK solution,is safe and effective in kidney preservation.

Objective To study the relationship of soluble LAIR (sCD305 and CD3060) expression in recipient serum with cytomegalovirus (CMV) pneumonitis after renal transplantation. Methods Nineteen serum specimens from recipients were divided into CMV pneumonitis group (n=10) and control group (n=9). Then the concentrations of sCD305 and CD3060 were quantitated with sandwich ELISA. The data were analyzed by using student t test. Results sCD305 was skewness distributed in both 2 groups, was 0.000-3.039 μg/L in CMV pneumonitis group and 0.000-8.375 μg/L in con-trol group. CD3060 was skewness distributed in CMV pneumonitis group and the concentration was 0.000-0.017μg/L. CD3060 was mormally distributed in control group and the concentration was 0.046±0.035 μg/L. There was significant difference of CD3060 (P=0.000) concentrations and no sig-nificant difference of sCD305(P=0.316) concentrations in 2 groups, respectively. Conclusions The concentration of CD3060 is low in CMV pneumonitis patients. The combination of CMV PP65 antigen detection and CD3060 detection is helpful for the early and precise diagnosis of CMV pneumonitis in renal transplantation patients.
