ABSTRACT

Acromicric dysplasia(AD) is a rare skeletal dysplasia characterized by severe short stature, short hands and feet, normal intelligence, mild facial dysmorphism, and radiological characteristics. The clinical data and genetic test results of one patient with AD in our hospital were analyzed, and the clinical characteristics of this case were summarized. The main manifestations of the child were short stature, short hands and feet, mild facial dysmorphism, short and stubby metacarpals and phalanges on hand X-ray. One mutation, FBN1: c.5141T>G(p.Met1714Arg), was identified in this child, the mutation is inherited from her short mother and grandfather. AD is a rare congenital skeletal dysplasia disorder associated with mutations in the FBN1 gene. It conforms to the pathogenesis of autosomal dominant genetic disease.

ABSTRACT

Objective:To evaluate the preliminary effectiveness and safety of surgical peripheral iridectomy (SPI) combined with goniosynechilysis (GSL) and goniotomy (GT) in the treatment of advanced primary angle-closure glaucoma (PACG).Methods:A multicenter observational case series study was performed.Thirty-five eyes of 27 patients with advanced PACG, who underwent SPI+ GSL+ GT with a follow-up of at least 6 months, were included from August 2021 to January 2022 at Zhongshan Ophthalmic Center, Handan City Eye Hospital, Shijiazhuang People's Hospital, West China Hospital of Sichuan University, and the Third Affiliated Hospital of Chongqing Medical University.The mean follow-up time was 9(7, 10) months.Pre- and post-operative best corrected visual acuity (BCVA) and intraocular pressure (IOP) were measured with an ETDRS chart and a Goldmann applanation tonometer, respectively.The number of anti-glaucoma medications applied before and after surgery was recorded, and the complications after surgery were analyzed.Success rate of surgery was calculated.Complete surgical success was defined as an IOP of 5-18 mmHg (1 mmHg=0.133 kPa) and 20% reduction from baseline without anti-glaucoma medication or reoperation.Qualified success was defined as achieving criterion of complete success under anti-glaucoma medications.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Zhongshan Ophthalmic Center, Sun Yat-sen University (No.2021KYPJ177). Written informed consent was obtained from each subject.Results:The mean preoperative IOP was (30.83±8.87)mmHg, which was significantly decreased to (15.69±3.70)mmHg at 6 months after the surgery ( t=8.588, P<0.001), with a 44.00% (34.78%, 60.00%) decline of 13.00(8.00, 21.00)mmHg.The median number of anti-glaucoma medications was significantly reduced from 2(0, 3) preoperatively to 0 (0, 1) postoperatively ( Z=-3.659, P<0.001). The mean preoperative and postoperative 6-month BCVA were 0.80(0.63, 1.00) and 0.80(0.60, 1.00), respectively, showing no significant difference ( Z=-0.283, P=0.777). Complete surgical success rate was 62.86%(22/35), and the qualified success rate was 91.43%(32/35). Surgical complications mainly included hyphema (6/35), IOP spike (3/35), and shallow anterior chamber (4/35). There was no vision-threatening complication. Conclusions:SPI+ GSL+ GT is preliminarily effective and safe in the treatment of advanced PACG, which provides a new option for PACG.

ABSTRACT

Objective: This cross-sectional investigation aimed to determine the incidence, clinical characteristics, prognosis, and related risk factors of olfactory and gustatory dysfunctions related to infection with the SARS-CoV-2 Omicron strain in mainland China. Methods: Data of patients with SARS-CoV-2 from December 28, 2022, to February 21, 2023, were collected through online and offline questionnaires from 45 tertiary hospitals and one center for disease control and prevention in mainland China. The questionnaire included demographic information, previous health history, smoking and alcohol drinking, SARS-CoV-2 vaccination, olfactory and gustatory function before and after infection, other symptoms after infection, as well as the duration and improvement of olfactory and gustatory dysfunction. The self-reported olfactory and gustatory functions of patients were evaluated using the Olfactory VAS scale and Gustatory VAS scale. Results: A total of 35 566 valid questionnaires were obtained, revealing a high incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain (67.75%). Females(χ2=367.013, P<0.001) and young people(χ2=120.210, P<0.001) were more likely to develop these dysfunctions. Gender(OR=1.564, 95%CI: 1.487-1.645), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), oral health status (OR=0.881, 95%CI: 0.839-0.926), smoking history (OR=1.152, 95%CI=1.080-1.229), and drinking history (OR=0.854, 95%CI: 0.785-0.928) were correlated with the occurrence of olfactory and taste dysfunctions related to SARS-CoV-2(above P<0.001). 44.62% (4 391/9 840) of the patients who had not recovered their sense of smell and taste also suffered from nasal congestion, runny nose, and 32.62% (3 210/9 840) suffered from dry mouth and sore throat. The improvement of olfactory and taste functions was correlated with the persistence of accompanying symptoms(χ2=10.873, P=0.001). The average score of olfactory and taste VAS scale was 8.41 and 8.51 respectively before SARS-CoV-2 infection, but decreased to3.69 and 4.29 respectively after SARS-CoV-2 infection, and recovered to 5.83and 6.55 respectively at the time of the survey. The median duration of olfactory and gustatory dysfunctions was 15 days and 12 days, respectively, with 0.5% (121/24 096) of patients experiencing these dysfunctions for more than 28 days. The overall self-reported improvement rate of smell and taste dysfunctions was 59.16% (14 256/24 096). Gender(OR=0.893, 95%CI: 0.839-0.951), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), history of head and facial trauma(OR=1.180, 95%CI: 1.036-1.344, P=0.013), nose (OR=1.104, 95%CI: 1.042-1.171, P=0.001) and oral (OR=1.162, 95%CI: 1.096-1.233) health status, smoking history(OR=0.765, 95%CI: 0.709-0.825), and the persistence of accompanying symptoms (OR=0.359, 95%CI: 0.332-0.388) were correlated with the recovery of olfactory and taste dysfunctions related to SARS-CoV-2 (above P<0.001 except for the indicated values). Conclusion: The incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain is high in mainland China, with females and young people more likely to develop these dysfunctions. Active and effective intervention measures may be required for cases that persist for a long time. The recovery of olfactory and taste functions is influenced by several factors, including gender, SARS-CoV-2 vaccination status, history of head and facial trauma, nasal and oral health status, smoking history, and persistence of accompanying symptoms.

ABSTRACT

Objective: To preliminarily explore the mechanism of tensile stress regulating endochondral osteogenesis of condyle by analyzing the expression profiles of significantly different microRNAs (miRNAs) in exosomes of rat mandibular condylar chondrocytes (MCC) under quiescent and cyclic tensile strain (CTS) conditions. Methods: Rat condylar chondrocytes were cultured under static and CTS conditions respectively (10 SD rats, male, 2 weeks old), and exosomes were extracted. The two groups of exosomes were named as control group and CTS group respectively. The differential expression miRNAs were screened by high-throughput sequencing. Bioinformatics analysis and prediction of target genes related to osteogenesis were performed by TargetScan and miRanda website. Results: The exosomes of rat condylar chondrocytes cultured under tensile stress showed a "double concave disc" monolayer membrane structure, the expression of CD9 and CD81 were positive, and the particle size distribution accorded with the characteristics of exosomes, which was consistent with that of static cultured rat condylar chondrocytes. A total of 85 miRNAs with significantly different expression were detected by high-throughput sequencing (P<0.05). The main biological processes and molecular functions of differential miRNAs were biological processes and protein binding, respectively. Kyoto Encyclopedia of Genes and Genomes (KEGG) database pathway enrichment analysis showed that there was significant enrichment in mammalian target of rapamycin (mTOR) signal pathway. The candidate target genes of miR-199a-5p include bone morphogenetic protein 3 (BMP3), endothelin converting enzyme 1, and miR-186-5p may target Smad8 and BMP3 to exert osteogenesis-related functions. Conclusions: Compared with static state, tensile stress stimulation can change the expression of miRNAs such as miR-199a-5p, miR-186-5p in the exocrine body of rat condylar chondrocytes, which can be considered as a mean to regulate the application potential of the exosomes.

ABSTRACT

Objective: To identify the risk factors in mortality of pediatric acute respiratory distress syndrome (PARDS) in pediatric intensive care unit (PICU). Methods: Second analysis of the data collected in the "efficacy of pulmonary surfactant (PS) in the treatment of children with moderate to severe PARDS" program. Retrospective case summary of the risk factors of mortality of children with moderate to severe PARDS who admitted in 14 participating tertiary PICU between December 2016 to December 2021. Differences in general condition, underlying diseases, oxygenation index, and mechanical ventilation were compared after the group was divided by survival at PICU discharge. When comparing between groups, the Mann-Whitney U test was used for measurement data, and the chi-square test was used for counting data. Receiver Operating Characteristic (ROC) curves were used to assess the accuracy of oxygen index (OI) in predicting mortality. Multivariate Logistic regression analysis was used to identify the risk factors for mortality. Results: Among 101 children with moderate to severe PARDS, 63 (62.4%) were males, 38 (37.6%) were females, aged (12±8) months. There were 23 cases in the non-survival group and 78 cases in the survival group. The combined rates of underlying diseases (52.2% (12/23) vs. 29.5% (23/78), χ2=4.04, P=0.045) and immune deficiency (30.4% (7/23) vs. 11.5% (9/78), χ2=4.76, P=0.029) in non-survival patients were significantly higher than those in survival patients, while the use of pulmonary surfactant (PS) was significantly lower (8.7% (2/23) vs. 41.0% (32/78), χ2=8.31, P=0.004). No significant differences existed in age, sex, pediatric critical illness score, etiology of PARDS, mechanical ventilation mode and fluid balance within 72 h (all P>0.05). OI on the first day (11.9(8.3, 17.1) vs.15.5(11.7, 23.0)), the second day (10.1(7.6, 16.6) vs.14.8(9.3, 26.2)) and the third day (9.2(6.6, 16.6) vs. 16.7(11.2, 31.4)) after PARDS identified were all higher in non-survival group compared to survival group (Z=-2.70, -2.52, -3.79 respectively, all P<0.05), and the improvement of OI in non-survival group was worse (0.03(-0.32, 0.31) vs. 0.32(-0.02, 0.56), Z=-2.49, P=0.013). ROC curve analysis showed that the OI on the thind day was more appropriate in predicting in-hospital mortality (area under the curve= 0.76, standard error 0.05,95%CI 0.65-0.87,P<0.001). When OI was set at 11.1, the sensitivity was 78.3% (95%CI 58.1%-90.3%), and the specificity was 60.3% (95%CI 49.2%-70.4%). Multivariate Logistic regression analysis showed that after adjusting for age, sex, pediatric critical illness score and fluid load within 72 h, no use of PS (OR=11.26, 95%CI 2.19-57.95, P=0.004), OI value on the third day (OR=7.93, 95%CI 1.51-41.69, P=0.014), and companied with immunodeficiency (OR=4.72, 95%CI 1.17-19.02, P=0.029) were independent risk factors for mortality in children with PARDS. Conclusions: The mortality of patients with moderate to severe PARDS is high, and immunodeficiency, no use of PS and OI on the third day after PARDS identified are the independent risk factors related to mortality. The OI on the third day after PARDS identified could be used to predict mortality.

ABSTRACT

The goal of this work was to explore the prospect of standardized application of an in-vitro bioactivity assay for recombinant human follicle-stimulating hormone based on a reporter gene. The relative accuracy, intermediate precision, linearity and applicable range of the method were validated according to the General Rules of Chinese Pharmacopoeia 2020 edition Volume IV (9401). Three laboratories used this method to determine the in-vitro biological activities of six batches of drug product and three batches of drug substance manufactured by two different companies. The consistency of the potency determined by three laboratories, the intra-laboratory precision and inter-laboratory precision were analyzed. The method was optimized during the collaborative validation. The results of method validation meet the requirements of the General Rules of Chinese Pharmacopoeia 2020 edition Volume IV (9401). Aiming to resolve the problems found in the collaborative validation, the medium for cell seeding, the pre-diluted buffer solution of standard and sample, and the means of removing and discarding supernatant after stimulation were optimized. After optimization, there was no significant difference in the bioactivity among the different laboratories (P > 0.05), indicating statistical equivalency. Intra-laboratory and inter-laboratory precision were good and the geometric coefficient of variation (GCV%) were both less than 15%. In conclusion, the reporter gene assay has good intra-laboratory repeatability and inter-laboratory reproducibility and is suitable for analyzing recombinant human follicle-stimulating hormone drug product and drug substance by different manufacturers. It is expected to be used as a standardized method for the determination of the in-vitro bioactivity of such products.

ABSTRACT

Objective To evaluate the impact of deep learning reconstruction algorithm on the image quality of head and neck CT angiography (CTA) at 100 kVp. Methods CT scanning was performed at 100 kVp for the 37 patients who underwent head and neck CTA in PUMC Hospital from March to April in 2021.Four sets of images were reconstructed by three-dimensional adaptive iterative dose reduction (AIDR 3D) and advanced intelligent Clear-IQ engine (AiCE) (low,medium,and high intensity algorithms),respectively.The average CT value,standard deviation (SD),signal-to-noise ratio (SNR),and contrast-to-noise ratio (CNR) of the region of interest in the transverse section image were calculated.Furthermore,the four sets of sagittal maximum intensity projection images of the anterior cerebral artery were scored (1 point:poor,5 points:excellent). Results The SNR and CNR showed differences in the images reconstructed by AiCE (low,medium,and high intensity) and AIDR 3D (all P<0.01).The quality scores of the image reconstructed by AiCE (low,medium,and high intensity) and AIDR 3D were 4.78±0.41,4.92±0.27,4.97±0.16,and 3.92±0.27,respectively,which showed statistically significant differences (all P<0.001). Conclusion AiCE outperformed AIDR 3D in reconstructing the images of head and neck CTA at 100 kVp,being capable of improving image quality and applicable in clinical examinations.

ABSTRACT

【Objective】 To establish a stable human megakaryocytic cell line with low expression of Ley antigen to further study the role of Ley on activation of platelets. 【Methods】 The expression level of the Ley antigen in a human megakaryocytic cell line, DAMI, was determined using Western Blot and flow cytometry. The expression level of genes that encode fucosyltransferase (FUTs), which was involved in the biosynthesis of Ley antigen, was also determined to identify the candidate genes to be knocked out. The candidate FUT gene was knocked out via a CRISPR/Cas 9 gene knockout system and cells with low Ley antigen expression were sorted by flow cytometry. The sorted cell line was cultured and characterized. 【Results】 The Ley was expressed intensively on DAMI cell. FUT1 and FUT4 mRNA was expressed relatively higher, both may be key enzymes for the biosynthesis of the Ley antigen. In the DAMI cell line with the knockout of FUT1 gene, the expression of the Ley adntigen was remarkedly reduced, while cell proliferation was not affected compared to the wildtype control cells. 【Conclusions】 Since various FUTs contributes to the biosynthesis of the Ley antigen, the knockout of the primary one of them cannot totally block its biosynthesis, but only reduce its expression. In this study, a stable FUT gene knockout human megakaryocyticcell line is established using CRISPR/Cas 9 technology, which provides basis for the study of the impact of the Ley antigen on platelet functions.

ABSTRACT

Trisomy 11 mosaicism is clinically rare, for which making diagnostic and treatment decisions can be challenging. In this study, we used noninvasive prenatal testing, chromosome karyotype analysis, chromosome microarray analysis, copy number variation sequencing and fluorescence in situ hybridization for detecting trisomy 11 mosaicism in two cases and provided them with genetic counseling. In one of the cases, the fetus with confined placental mosaicism trisomy 11 presented with severe growth restriction and a placental mosaic level of 44%, and pregnancy was terminated at 25+3 weeks of gestation. In the other case with true low-level fetal mosaicism of trisomy 11, the pregnancy continued after exclusion of the possibility of uniparental disomy and structural abnormalities and careful prenatal counseling. The newborn was followed up for more than one year, and no abnormality was found. Noninvasive prenatal testing is capable of detecting chromosomal mosaicism but may cause missed diagnosis of true fetal mosaicism. For cases with positive noninvasive prenatal testing but a normal karyotype of the fetus, care should be taken in prenatal counseling and pregnancy management.

ABSTRACT

Objective:To analyze the career development path and related problems of general practitioners (GPs)in the community.Methods:In October 2019, general practitioners with different positions working in Malu Town Community Health Service Center of Shanghai Jiading district were selected by typical sampling to participate in a focus group interview. Based on the saturation principle, 5 general practitioners were invited for in-depth interviews on their career development and related issues. The original data were analyzed with Colaizzi′s seven-step analysis method.Results:The career development of the general practitioners working in the community was divided into three stages: start stage, experience-accumulation stage and career-differentiation stage. In the start stage (the first 0-24 months), the GPs mainly got familiar with the community health service center through community rotation. In the experience-accumulation stage (1-5 years after entering the community health service center), GPs accumulated clinical experience from outpatient clinic, ward, and being family doctor, etc; at the same time, they accumulated management experience through part-time public health management, research and education management, secondment in district health committee. In the professional differentiation stage (5 years or more after entering the community health service center), GPs may take a position of full-time management, or department head. The three respondents had confusion in certain career development stages, including confusion in clinical skills upgrading and balance between clinical and management duties.Conclusions:The study suggests that general practitioners in the entry stage need to be given timely clinical rotation as well as research and teaching training; in the career differentiation stage, it is necessary to incorporate upgrading clinical service and management capability with policy development directions and institutional development needs to promote the successful career differentiation of general practitioners.

ABSTRACT

Objective:To explore the application and effect of multi-level quality control system (referred to as “quality control”) in health management center setting.Methods:The health management center of Hanzhong Central Hospital constructed a multi-level quality control system of “hospital-department-unit” and “department-unit-quality-controller” in August 2019. A total of 83 619 people who underwent physical examination in the Health Management Center of Hanzhong Central Hospital from August 2018 to July 2020 were selected as the subjects. 32 009 people who underwent physical examination from August 2018 to July 2019 were selected as the control group, and 51 610 people who underwent physical examination from August 2019 to July 2020 were selected as the experimental group. The timely notification of important abnormal results and the follow-up of the “four-high” population (hypertension, hyperglycemia, hyperlipidemia, and hyperuricemia) were observed. Two thousand satisfaction questionnaires and two thousand physical examination reports were collected from the institutions who had received both physical examination in the Health Management Center of Hanzhong Central Hospital for two consecutive years. The physical examination items of the above clients were basically the same. The satisfaction rate of the two groups of physical examination and the qualification rate of the physical examination reports were measured respectively.Results:The results showed that the timely notification rate of important abnormal results (99.4% vs 96.6%), follow-up rate of “four-high” population (hypertension 95.1% vs 91.2%, hyperglycemia 95.3% vs 91.6%, hyperlipidemia 94.6% vs 92.3%, hyperuricemia 92.7% vs 86.4%), satisfaction rate of physical examination (physical examination environment 94.0% vs 91.3%, service attitude 96.4% vs 91.9%, waiting time 97.6% vs 95.4%, physical examination process 98.3% vs 96.8%, professional level of medical staff 97.2% vs 95.1%), and qualified rate of physical examination report (accuracy of input information 99.5% vs 98.1%, accuracy of main examination conclusion 99.4% vs 97.3%, normative sorting 99.8% vs 98.8%, rationality of health advice 99.2% vs 96.8%) in the experimental group were significantly higher than those in the control group (all P<0.05). Conclusion:The establishment of a multi-level quality control system in health examination service can improve the timely notification rate of important abnormal results, the follow-up rate of the “four-high” population, the satisfaction of physical examinees, and the qualified rate of physical examination reports.

ABSTRACT

Objective:To investigate the longitudinal trajectory and influencing factors of cancer-related fatigue (CRF) in breast cancer patients during chemotherapy.Methods:From March 2019 to January 2020, breast cancer patients in Longhua Hospital Affiliated to Shanghai University of Traditional Chinese Medicine, Yueyang Hospital of Integrated Traditional Chinese and Western Medicine Affiliated to Shanghai University of Traditional Chinese Medicine and Peking Union Medical College Hospital were selected as the research objects to conduct follow-up investigation. The survey tools included general information questionnaire, Cancer-related Fatigue Assessment Scale, International Physical Activity Questionnaire, and the Pittsburgh Sleep Quality Index Scale.Results:A total of 91 patients were included in the study. The incidence of severe CRF at each time point before chemotherapy, 3 weeks after chemotherapy and 6 weeks after chemotherapy were 1.1% (1/91), 8.8% (5/57) and 2.1% (1/48), respectively. The results of the generalized estimation equation showed that the trajectory of the total score CRF firstly increased and then decreased, reaching a peak at 3 weeks after chemotherapy (35.45±13.07), and mild CRF change showed statistical difference ( P<0.05). In addition, BMI and sleep and daytime dysfunction were the influencing factors of the total score of CRF. Disease stage, sleep disturbance and daytime dysfunction were the influencing factors of CRF with different severity.

ABSTRACT

OBJECTIVE@#To investigate the expression of matrix metalloproteinase-2 (MMP-2) and matrix metalloproteinase-9 (MMP-9) in multiple myeloma (MM) patients, and analyze the effect of doxycycline (DOX) on the expression of MMP-2 and MMP-9 in MM cells.@*METHODS@#The peripheral blood and bone marrow samples of MM patients were collected, and the patients were divided into three groups: newly diagnosed group, remission group and relapsed/refractory group, while the peripheral blood samples of 34 health people and the bone marrow samples of 17 IDA patients were selected as normal control and control group. The levels of MMP-2 and MMP-9 were detected by ELISA. The protein levels of MMP-2 and MMP-9 in H929 cells treated by different concentrations of DOX were analyzed by Western blot. After H929 cells was treated by Akt inhibitor MK-2206 2HCl in combination with DOX, Western blot was used to detect the levels of MMP-2 and MMP-9.@*RESULTS@#The levels of MMP-2 and MMP-9 in newly diagnosed MM patients were higher than those in control (P<0.05), while for the patients in the remission group were decreased, but still higher than those in control. The levels of MMP-2 and MMP-9 were increased again for the patients in relapsed/refractory group, and showed no significant difference as compared with those in newly diagnosed group. The levels of MMP-2 and MMP-9 could be inhibited by 10 mg/L and 15 mg/L DOX treated by H929 cell. The protein levels of MMP-2 and MMP-9 showed no altered in H929 cells treated by 5 nmol/L MK-2206 2HCl alone. DOX exerted more profound inhibitory effect to MMP-2 and MMP-9 expression in H929 cells when Akt inhibitor MK-2206 2HCl was combined with DOX.@*CONCLUSION@#The levels of MMP-2 and MMP-9 are increased in MM patients and related to the disease status of MM. DOX can inhibit the expression of MMP-2 and MMP-9 in MM cells, and antagonizing its activation of Akt signaling pathway can further enhance the inhibitory effect.

ABSTRACT

This study is to evaluate the application of the comprehensive capacity assessment system based on post competence in competitive recruitment of family doctors. Thirty five general practitioners participating in the family doctor post competition in 2019—2020 were graded and ranked by both the post competition method and the comprehensive capacity assessment system of family doctors. The top 32 candidates in terms of total scores were selected as the successful candidates for the family doctor job competition. Kappa test was used to assess the consistency of competition results between the two methods. Among 32 candidates who were qualified according to the 2019—2020 family doctors post competition method, 31 (96.9%) were also qualified for the family doctor′s comprehensive capacity assessment system ( Kappa=0.635, P<0.01). The results indicate that the comprehensive capacity assessment system for family doctors based on post competency is rational and objective, and can be used for competitive recruitment of family doctors in community health service center.

ABSTRACT

Objective:To investigate the effects of PDCA method on improving the accuracy of the Autar Deep Venous Thrombosis (DVT) Scale used by nurses to assess the risk of deep venous thrombosis in surgical patients.Methods:Applied the way of PDCA, namely, raising questions, analyzing reasons, implementing measures, feeding back effects to professional explanate the difficulty in using the scale, moreover, training the nurses used level education method between August 2017 and December2018.The accuracy and consistency of the scale were compared before and after interventions.Results:A total 396 patients were evaluated in the study. There were significant differences in the consistency of evaluation among hospitalized, post-operative and discharged patients after intervention compared with before intervention ( P< 0.0167).The consistency of assessment of team members and responsible nurses increased from 68 to 120 cases, and the consistency of assessment reached 90.91%. The Kappa consistency of assessment of responsible nurses and team members increased from 0.354 before intervention to 0.879 after intervention. The effect was remarkable. Conclusions:PDCA cycle method is based on the problems found in clinical practice. It clarifies the professional terms and rules used in the scale, improves the accuracy and consistency of the Autar DVT scale used by nurses, correctly reflects the risk of thrombosis, ensures the safety of patients, and is worthy of promotion and reference.

ABSTRACT

Objective To characterize the epidemic status and treatment outcomes of tuberculosis(TB)from 2008 to 2017 in Songjiang District of Shanghai for the development of TB prevention and control strategies. Methods According to case registration data in the TB management information system, statistical analysis was performed on the epidemic situation, epidemiological characteristics and treatment outcomes of TB cases in Songjiang District from 2008 to 2017. Results There were 5 516 reported cases in 2008-2017 in Songjiang District. The average annual reported incidence was 33.58/100 000, which was declining(χ2 = 6.13, P < 0.05). The incidence was significantly higher in the floating population than that in the household registered population(χ2 = 263.28, P < 0.05). In the cases, gender ratio was 2.17 : 1. More than 70% of the cases were between 15 and 44 years old. The majority of the cases were workers(34.95%), followed by housework or unemployed(16.28%). The proportion of TB case responding to the treatment was 93.38%, which was 93.41% for newly diagnosed cases and 92.86% for previously treated cases. The failure rate in the previously treated smear-positive cases was significantly higher than newly treated smear-positive cases(χ2 = 4.96, P < 0.05). Conclusion TB epidemic in Songjiang District remained at a low level in 2008-2017;however, it is far away from the termination of TB. We should further strengthen the prevention and control of TB, especially in the 15-44 years old workers and unemployed young population.

ABSTRACT

Biological complexity and the need for personalized medicine means that biomarker development has become increasingly challenging. Thus, new paradigms for research need to be created that bring together a different classifier of individuals. One potential solution is collaboration between biomarker development and Chinese medicine pattern classification. In this article, two examples of rheumatoid arthritis are discussed, including a new biomarker candidate casein kinase 2 interacting protein 1 (CKIP-1) and a micro RNA 214. The authors obtained a "snapshot" of pattern classification with disease in biomarker identification. Bioinformatics analyses revealed underlying biological functions of two biomarker candidates, in varying degrees, are correlated with Chinese medicine pattern of rheumatoid arthritis. The authors' initial attempt can provide a new window for studying the win-win potential correlation between the biomarkers and pattern classification in Chinese medicine.
