ABSTRACT

Digital polymerase chain reaction (dPCR) is an absolute quantitative technique that has been rapidly developed in recent years. This technique assigns the reaction system containing DNA template to a large number of independent reaction units for PCR, and calculates the DNA copy number according to the Poisson distribution and statistical positive signals. In contrast to conventional qPCR, dPCR does not depend on amplification curves, is not affected by amplification efficiency, thus has high accuracy and repeatability, and can achieve the absolute quantification. This article reviews the development history of dPCR and its application in molecular diagnosis, tumor liquid biopsy and prenatal diagnosis of infectious diseases, and looks forward to the application prospect of this technology.

ABSTRACT

Objective:To investigate the effects of allogeneic hematopoietic stem cell transplantation (allo-HSCT) in treatment of high-risk multiple myeloma (MM) patients and its influencing factors of the prognosis.Methods:The clinical data of 44 high-risk MM patients treated with allo-HSCT in Changzheng Hospital Affiliated of Naval Military Medical University from April 2003 to March 2017 were retrospectively analyzed. The overall response rate (ORR), relapse rate, non-relapse-related death (NRM) rate, graft-versus-host disease (GVHD) incidence of patients were also analyzed. Kaplan-Meier was used to analyze the overall survival (OS) rate and progression-free survival (PFS) rate after transplantation. Cox proportional hazard model was used to make regression analysis of the factors affecting the prognosis.Results:Among 44 patients, 38 cases could be evaluated for efficacy after transplantation. The median follow-up time was 111 months (0-216) months, 22 cases survived, 22 cases died, 21 cases relapsed. Before transplantation, complete remission (CR) rate was 29.5%(13/44), very good partial remission(VGPR) rate was 45.5%(20/44), partial remission (PR) rate was 22.7% (10/44), stable disease (SD) rate was 2.3% (1/44); After transplantation, CR rate was 71.7%(27/38), VGPR rate was 13.2% (5/38), PR rate was 13.2% (5/38), the progression of the disease (PD) rate 2.6% (1/38). The 5-year OS rate and PFS rate was 51.8% and 47.8%, the 10-year OS rate and PFS rate was 51.3% and 43.1%, respectively; the 5-year and 10-year cumulative disease relapse rate was 38.6% and 45.4%, the 5-year cumulative NRM rate was 25.0%. Acute GVHD rate was 38.6% (17/44) and grade 3-4 acute GVHD rate was 6.8% (3/44); chronic GVHD rate was 27.3% (12/44). Cox univariate and multivariate analysis showed that the use of bortezomib before transplantation ( HR = 3.461, 95% CI 1.211-9.880, P = 0.020) and post-transplant infection ( HR = 0.283, 95% CI 0.098-0.819, P = 0.020) were independent factors affecting OS after transplantation. Conclusions:Allo-HSCT can overcome the high-risk factors of MM and is worth to try for high-risk MM patients. The use of bortezomib before transplantation and post-transplant infection can be important factors affecting OS after transplantation.

ABSTRACT

Objective@#To investigate the awareness and identify the influencing factors of sexual knowledge among primary and middle school students in Butuo County, Sichuan Province, so as to provide insights into sex education.@*Methods@#Six primary and middle schools were randomly sampled from 40 primary and middle schools in Butuo County using the cluster sampling method on March and April, 2021, and a class was randomly sampled from each of grades 4 to 6 of primary schools and grades 1 to 3 of junior high schools, with all students from the class as study subjects. Students' demographic features and awareness of sexual knowledge were investigated using self-designed questionnaires, and the factors affecting the awareness of sexual knowledge were identified among primary and middle school students using multivariable linear regression analysis.@*Results@#A total of 980 questionnaires were allocated, and 957 valid questionnaires were recovered, with an effective recovery rate of 97.65%. The respondents included 458 boys ( 47.86% ) and 499 girls ( 52.14% ), and included 908 students with Yi Ethnicity. The respondents included 802 primary school students ( 83.80% ) and 155 junior high school students ( 16.20% ). The awareness of sexual knowledge was 21.94% among the primary and middle school students, and their sexual knowledge was predominantly derived from parents ( 338 students, 35.32% ) and teachers ( 335 students, 35.01% ). The awareness of sexual knowledge was significantly lower in boys than in girls ( 17.69% vs. 25.86%; χ2=8.344, P=0.004 ), and the awareness of sexual knowledge appeared a tendency towards a rise with age ( χ2trend = 63.908, P<0.001 ). Low awareness of sexual knowledge was seen in students with fathers going out for labor ( 19.54% ), mothers going out for labor (11.24%) and living in the countryside ( 14.32% ) ( χ2=7.790, 9.224 and 34.144, all P<0.01 ). Multivariable linear regression analysis showed that students living in the countryside, students’ mothers going out for labor, ages of 12 to 14 years and ages of over 14 years were factors affecting the score of sexual knowledge ( β'=-0.072, 0.341, 0.645 and 0.843, all P<0.05 ).@*Conclusions@#The awareness of sexual knowledge is low among primary and middle school students in Butuo County. Health education of sexual knowledge should be emphasized on male students, those living in the countryside and students with mothers going out for labor.

ABSTRACT

Objective To understand the status of depression and anxiety in patients with chronic hepatitis B in Tianjin, and to analyze its influencing factors, so as to provide references for scientific psychological intervention and health education. Methods Chronic hepatitis B cases whose addresses were Tianjin were randomly selected from the report of infectious disease surveillance system from January 2018 to December 2019 as the study subjects. A certain number of healthy people living in Tianjin were selected as the control. A unified mental health questionnaire survey was conducted by telephone follow-up or face-to-face survey. The distribution characteristics of depression and anxiety were described, and influencing factors of depression and anxiety were analyzed by univariate and multivariate logistic regression analysis. Results A total of 825 cases of chronic hepatitis B and 376 cases of healthy people were investigated. The crude SDS and SAS were (35.47±9.34) and (32.33±8.26), respectively, which were higher than those of healthy people ( P <0.05). The rates of depression and anxiety in chronic hepatitis B patients were 25.45% and 20.61%, respectively, which were significantly higher than those in healthy people (15.96% and 11.70%, respectively) (P < 0.001). The analysis of depression influencing factors showed that the OR of high average monthly income was 0.791 ( 95% CI:0.655~0.955 ), the OR of not knowing correct preventive measures was 1.509 (95% CI:1.084~2.102 ), and the OR of feeling discriminated was 1.650 ( 95% CI:1.166~2.335 ). The multifactor analysis of anxiety influencing factors showed that the OR of not knowing correct preventive measures was 1.490 ( 95% CI:1.049~2.117)), while the OR of feeling discriminated was 1.854 ( 95% CI: 1.289~2.666). Conclusion The levels of depression and anxiety of chronic hepatitis B patients were higher than that of general healthy people. Not knowing correct preventive measures and feeling discriminated in daily life were risk factors while high income was a protective factor.

ABSTRACT

Objective@#To evaluate the prognostic value of serum free light chain ratio (rFLC) and difference (dFLC) in patients with multiple myeloma (MM) .@*Methods@#Clinical data of 479 cases of newly diagnosed MM patients with FLC test records referred to our hospital from January 2012 to March 2016 were collected. rFLC preferred cut-off values were selected as≤14.828,14.828-364.597, ≥364.597 according to the literatures. The dFLC was divided into ≤112.85,112.85-2891.83, ≥2891.83 mg/L three groups. The rFLC and dFLC values among the death, the non-death, the progress and the non-progress groups were compared by t test. The correlation analysis showed that the rFLC and dFLC values were related to the death or progression of the disease. Logistic regression was used to analyze the correlation between each factor and death or progression. Univariate survival analysis (PFS) and total survival (OS) were performed using Kaplan-Meier. Single-variable and multivariate prognostic analysis were performed using Cox model.@*Results@#The cutoff values of rFLC less than 14.828 or dFLC less than or equal to 112.85 mg/L impacted most significant on OS and PFS of the patients (P<0.05) . Different rFLC cut-off values between two groups showed that when rFLC=14.828, OS was significantly better than the other two groups (NR vs 61 & 47 months, P=0.019) ; different dFLC cut-off values between two groups disclosed that PFS and OS were statistically significant when dFLC less than or equal to 112.85 mg/L compared with the other two groups (P<0.05) . The 4-year PFS/OS rates in the initial dFLC≤112.85 mg/L and rFLC≤14.828 groups was significantly higher than of the other two groups.@*Conclusion@#Different cutoff levels of rFLC and dFLC might have obviously effects on the prognoses of patients with newly diagnosed MM. The difference of survival prognosis would be more pronounced when rFLC≤14.828 or dFLC≤112.85 mg/L with lower risk of death and lower risk ratio, which might be ideal cutoff value for determining the prognosis of these patients.

ABSTRACT

Objective To access the clinical effect of medical radiation protective ointment compared with trolamine cream to prevent acute radiation-induced skin injury in breast cancer patients undergoing radiotherapy after modified radical mastectomy. Methods Between February 2017 and February 2018,a total of 120 stage T1-4 N1-3 M0 eligible patients received intensity modulated radiation therapy were enrolled and matches into two groups:study group (60 cases) was administered medical radiation protective ointment from the first irradiation fraction,and control group (60 cases) received trolamine cream. When 3 grade reaction was observed,patients in control group start to administer medical radiation protective ointment until a month after radiation. Results The occurrence rate of acute breast dermal radiation reaction was 100%.Most patients in study group only underwent 1 grade radiation reaction (82%),while 2 and 3 grade radiation reaction (47% and 13%) in control group were common ( P= 0. 000). Both pruritic degree and pain degree were higher in control group compared with study group (both P= 0. 000).In study group,the occurrence of 2 grade acute radiation-induced skin injury was obviously later than in control group with significant difference (P= 0. 000).Patients observed with 3 grade reaction relieved to certain reaction after administering medical radiation protective ointment. Conclusions Medical radiation protective ointment can effectively both alleviate and delay acute radiation-induced skin injury compared with trolamine cream. It also has therapeutic effect on 3 grade radiation reaction.

ABSTRACT

Objective@#To investigate the pathogen spectrum distribution and drug resistance of febrile neutropenic patients with hematological diseases in Shanghai.@*Methods@#A retrospective study was conducted on the clinical isolates from the febrile neutropenic patients hospitalized in the departments of hematology in 12 general hospitals in Shanghai from January 2012 to December 2014. The drug susceptibility test was carried out by Kirby-Bauer method. WHONET 5.6 software was used to analyze pathogenic bacteria and drug susceptibility data.@*Results@#A total of 1 260 clinical isolates were collected from the febrile neutropenic patients. Gram-positive bacteria accounted for 33.3% and Gram-negative bacteria accounted for 66.7%. Klebsiella pneumoniae (12.5%) , Stenotrophomonas maltophilia (9.5%) , Escherichia coli (9.1%) , Pseudomonas aeruginosa (8.7%) , Acinetobacter baumannii (6.6%) , Staphylococcus aureus (5.6%) and Enterococcus faecium (5.0%) were ranked in the first 7 of all pathogens. In the respiratory tract secretions specimens, non-fermented strains accounted for 56.2%. Stenotrophomonas maltophilia accounted for 15.2%. Enterobacteriaceae and coagulase-negative Staphylococci accounted for 42.3% (104/246) and 32.6% (85/246) respectively in blood samples. Enterobacteriaceae and Enterococcus bacteria accounted for 39.4% (76/193) and 28.5% (55/193) respectively in pus specimens. The detection rates of methicillin resistant Staphylococcus aureus (MRSA) and methicillin resistant coagulase negative Staphylococci (MRCNS) were 54.3% and 82.5%, respectively. Staphylococcus bacterial strain was not found to be resistant to linezolid, vancomycin and teicoplanin. The detection rate of Enterococcus vancomycin-resistant strains was 8.9%. Enterococcus was not detected resistance to oxazolidinone strains. Enterobacteriaceae bacteria were highly sensitive to carbapenems. The resistance rate of Pseudomonas aeruginosa to imipenem and meropenem was 34.1% and 15.8%, respectively. Stenotrophomonas maltophilia was more sensitive to minocycline hydrochloride, levofloxacin and sulfamethoxazole. The resistance rate of Acinetobacter baumannii only to cefoperazone-sulbactam was less than 10.0%. The antibiotic resistance rate of Klebsiella pneumoniae, Stenotrophomonas maltophilia, Pseudomonas aeruginosa and Acinetobacter baumanii to most of common antibiotics was lower than that of the CHINET surveillance.@*Conclusions@#The pathogenic strain distribution in common infection sites of febrile neutropenic patients was characterized. Bacterial resistance surveillance was better than the CHINET nationwide large sample surveillance in China.

ABSTRACT

Objective@#To explore the effect of 6 common cytogenetic abnormalities on the prognosis of multiple myeloma (MM).@*Methods@#Myeloma cells from a cohort of 532 newly-diagnosed MM patients enrolled were enriched by CD138 immunomagnetic beads, then detected 13q-, 17p-, 1q+, t (4;14), t (11;14) and t (14;16) and other common genetic abnormalities in MM by using interphase fluorescence in situ hybridization (FISH) technique to compare the influence of different genetic abnormalities on their prognoses.@*Results@#The rate of cytogenetic abnormalities was 78.20% (416/532) in 532 patients, of which 13q-accounted for 42.29% (225/532), 17p-16.35% (87/532), 1q+ 53.38% (284/532), t (4;14) 25.94% (138/532), t (11;14) 21.62% (115/532), t (14;16) 2.07% (11/532). Six kinds of cytogenetic abnormalities were analyzed, 13q- and 17p-, 1q+, t (4; 14), t (14;16) were all correlated (P <0.05). The univariate analysis indicated that 13q-, 1q+, t (4;14) and t (14;16) had a significant effect on progression-free survival (PFS), 13q-, 17p-, t (4;14) and t (14;16) had a marked influence on overall survival (OS). The multivariate analysis showed that 1q+, t (4;14) and t (14;16) were independent adverse factors of PFS, 17p-, t (4;14) and t (14;16) were independent unfavorable factors of OS. According to the independent prognosis factors number-based groups, the median PFS with 0, 1, 2, 3 independent prognosis factors of patients were 30.9, 28.4, 18.7 and 17.6 months (P =0.035) respectively, and the median OS were 54.4, 46.1, 38.0 and 21.2 months (P =0.004) respectively.@*Conclusion@#1q+, 17p-, t (4;14) and t (14;16) were independent prognostic factors affecting the survival of MM patients. 13q-is often accompanied by 17p-, 1q + and (or) t (4;14) , simply 13q- was not an independent prognostic factor; the more number of independent prognostic factors, the worse the prognosis of patients.

Objective@#To assess the prognostic value of revised international staging system (R-ISS) for multiple myeloma (MM) in real world.@*Methods@#A total of 202 newly diagnosis symptomatic MM patients were enrolled from May 2010 to April 2015 and the clinical data were retrospectively analyzed. All the patients received at least four courses of bortezomib-based or thalidomide-based induction therapy.@*Results@#With a median follow-up of 31 months, the cohort included 56 cases in R-ISSⅠ, 108 in R-ISS Ⅱ, and 38 in R-ISS Ⅲ, and the median OS was not reached/61/38 months, respectively (P=0.001). According to the ISS system, 62 patients were classified in ISS-Ⅰ, 70 in ISS-Ⅱ and 70 in ISS-Ⅲ, with the median OS was 58, 52 and 40 months, respectively (P=0.001). The relative risk (HR) of R-ISS stage Ⅲ vs Ⅰ, Ⅱ vs Ⅰ were 9.606 (P=0.008) and 4.038 (P=0.029). The HR of Ⅲ vs Ⅰ, Ⅱ vs Ⅰ of ISS system were 4.127 (P=0.070) and 2.877 (P=0.005). In the subgroup analysis, R-ISS predicted survival for patients who were not transplanted (P=0.003) , receiving bortezomib-based therapy (P=0.010) , and patients younger than 65 years (P=0.001).@*Conclusion@#R-ISS system could better predict prognosis for OS in unselected nonclinical trial myeloma patients than ISS system, especially for the younger patients, patients with bortezomib-based therapy, and patients without transplantation.

ABSTRACT

Objective To explore the effect of internet + continuing nursing education teaching methodflipped classroomin the teaching of Assessment of Consciousness among junior nurses. Methods A total of 98 nurses who have graduated within two years in the third hospital of Mianyang city in Sichuan province were selected and divided into experimental group and control group by random digits table method with 49 nurses each. The experimental group used flipped classroom teaching method and the control group used the traditional teaching method. After the training, the scores of examination and nurses′ learning satisfaction were analyzed and compared. Results The scores of nurses′ learning satisfaction in the experimental group was (100.35 ± 12.21) points, learning process, learning content, learning result, learning environment, interpersonal relationship of the dimensions were (26.85 ± 3.38), (22.02±3.07), (20.90±3.15), (17.19±2.50), (13.40±1.51) points. The scores of nurses′learning satisfaction in the control group was (86.00±11.63) points, learning process, learning content, learning result, learning environment, interpersonal relationship of the dimensions were (23.63±2.81), (19.67±3.06), (17.76±3.32), (15.20±2.46), (9.74±2.74) points. There were statistical differences between two groups(t=3.46-7.97, all P=0.000). The score of nurses′examination in the experimental group was (78.19±6.11) points,the score of nurses′ examination in the control group was (49.64 ± 14.42) points, and there was statistical difference between two groups(t=10.19, P=0.000). Conclusions Internet+continuing nursing education teaching methodflipped classroomcan improve junior nurses′learning satisfaction and the effect of the training, worthy of further promotion.

ABSTRACT

Objective: To compare the different therapeutic effects of acupuncture and Phenolphthalein for constipation due to intestinal qi stagnation. Methods:A total of 50 patients with constipation due to intestinal qi stagnation were randomly divided into an acupuncture group and a medication group by the random digital table, 25 cases in each group. The patients in the acupuncture group were treated by puncturing Gongsun (SP 4), Sanyinjiao (SP 6), Taichong (LR 3), Zusanli (ST 36), Shangjuxu (ST 37), Hegu (LI 4), Lieque (LU 7), and Tianshu (ST 25), once every day, and 7 d as one course, for continuous 3 courses; while the patients in the medication group were given Phenolphthalein, 7 d as one course, for continuous 3 courses. Compared the Cleveland clinic constipation score (CCS) between the two groups after one course, 3 courses and 3 months after the treatment, as well as the frequency of defecation within one week. Results:After one week of treatment, CCS scores and frequency of defecation per week were significantly changed in both groups compared with those before treatment (P<0.05), and CCS scores and frequency of defecation per week were improved more significantly in the patients of the medication group than in those of the acupuncture group (P<0.01). After 3 weeks of treatment, CCS scores and frequency of defecation per week were significantly changed in both groups compared with those before treatment (P<0.05), and CCS scores and frequency of defecation per week were improved more significant in the patients of the acupuncture group than in those of the medication group (P<0.05). Three months after the end of treatment, CCS scores and frequency of defecation per week were significantly changed in both groups compared with those before treatment (P<0.05), and CCS scores and frequency of defecation per week were improved more significantly in the patients of the acupuncture group than in those of the medication group (P<0.05). Conclusion:Acupuncture and medication are effective in the treatment of constipation due to intestinal qi stagnation. Their short-term therapeutic effect is similar, but the long-term therapeutic effect is better in the acupuncture group than in the medication group.

ABSTRACT

Objective To develop a observation table with influencing factors for catheter-associated urinary tract infections in critical patients and verify its reliability and validity. Methods Literature review, brainstorming method, expert interview and group discussion were performed to identify items of the form. By convenience sampling method, totally 130 severe patients with urinary catheter were investigated by this scale. This form was evaluated by item analysis, exploratory factor analysis and reliability and validity test. Results The observation table with influencing factors for Catheter-associated Urinary Tract Infections in critical patients consisted of five dimensions and 26 items. The cumulative contribution of variance was 73.752%, the Cronbach′s alpha coefficient was 0.869 and the Spearman-Brown split-half coefficient was 0.828. Regarding to the construct validity, the correlation coefficient between the each factor and total observation table was 0.652~0.873, the correlation coefficient between the factors was 0.311~0.823. All the difference of correlation coefficients were statistically significant (P<0.01). Conclusions The observation table with influencing factors for Catheter-associated Urinary Tract Infections in critical patients has been proved to be reliable and valid. It can be used as a valid tool to assess influencing factors for Catheter-associated Urinary Tract Infections in critical patients.
