Effectiveness of craniocervical flexion training combined with cervical traction among patients with cervical spondylotic radiculopathy / 预防医学

Objective@# To evaluate the effectiveness of craniocervical flexion training using pressure biofeedback combined with cervical traction among patients with cervical spondylotic radiculopathy (CSR).@*Methods@#Sixty patients with CSR receiving treatment in Center of Rehabilitation, Zhejiang Hospital from January 2020 to December 2021 were enrolled and randomly assigned into the control and treatment groups, of 30 patients in each group. All patients were given cervical traction, and patients in the treatment group were given additional craniocervical flexion training using pressure biofeedback for successive four weeks. The effectiveness of craniocervical flexion training combined with cervical traction was evaluated using Visual Analogue Scale (VAS), Neck Disability Index (NDI) and the active range of motion (AROM) of cervical flexion, and the neck pain and cervical functions were compared between the two groups before and after treatments using repeated-measures analysis of variance.@* Results@# Fifteen men were included in the treatment group, with a mean age of (49.47±5.33) years, mean disease course of (5.53±2.89) months, and mean VAS score of (4.73±1.39) points, and there were no significant differences between the control and treatment groups in terms of gender, age, course of disease or VAS score (P>0.05). The VAS score and NDI were lower 4 weeks post-treatment than pretreatment in both the treatment [VAS score: (2.13±1.01) vs. (4.73±1.39); NDI: (12.17±2.12) vs. (20.20±3.78)] and control groups [VAS score: (2.93±1.11) vs. (4.90±1.21); NDI: (15.23±2.39) vs. (19.60±3.30)], and the AROM of cervical flexion was significantly higher 4 weeks post-treatment than pretreatment in both the treatment [(42.87°±2.99°) vs. (37.50°±2.80°)] and control groups [(41.80°±3.61°) vs. (38.07°±2.99°)]; there was an interaction between time and group, and a higher improvement for cervical functions was seen in the treatment group than in the control group (FVAS =5.119, P=0.027; FNDI=15.473, P<0.001; FAROM=11.443, P<0.001). @*Conclusion@#Craniocervical flexion training using pressure biofeedback combined with cervical traction may effectively alleviate the neck pain and increase the AROM among patients with CRS, which is more effective to improve patients' cervical functions than cervical traction alone.

Mental health benefits of Tai Chi for college students: a systematic review using ICF / 中国康复理论与实践

ObjectiveTo construct the mental health benefits of physical activity of Tai Chi and framework for college students based on International Classification of Functioning, Disability, and Health (ICF), and to systematically review the effect of physical activity of Tai Chi on anxiety, depression and sleep quality of college students. MethodsRelevant literatures about the health outcomes on anxiety, depression and sleep quality of college students participating in physical activity of Tai Chi were retrieved from databases of Web of Science, PubMed, Medline, Scopus, CNKI, Wanfang data, from the establishment to November 10th, 2022, and screened and reviewed. ResultsTen randomized controlled trials were included finally, from China and U.S.， involving 960 participants (aged 16.4 to 40 years). The main sources were from journals about physical activity and health, with publication dates from 2016 to 2021. The quality of the included literatures was evaluated using the Physical Therapy Evidence Database (PEDro) scale with a mean score of 6.3. The main mental health problems of college students mainly focused on depression, anxiety, high stress, and poor sleep quality. The physical activity of Tai Chi included 24 simplified Tai Chi and Chen style Tai Chi. The frequency of physical activity of Tai Chi was mainly 1 to 6 times a week, 45 to 90 minutes (60 minutes mostly) a time, for 4 to 18 weeks. The health benefits of Tai Chi on anxiety, depression, and sleep quality for college students in the ICF were mainly in the affective function (b152), psychomotor function (b147), energy and drive function (b130), and sleep function (b134). The beneficial outcomes of physical activity of Tai Chi involved reducing anxiety, alleviating depressive symptoms and reducing stress. Compared with physical activity of Tai Chi, physical activity of Tai Chi with the addition of a twenty-four-pattern Taijiquan theory course was more effective in improving depression levels in patients with mild and moderate depression. Tai Chi also can help to improve sleep quality, shorten the time to sleep, and reduce sleep disturbances and daytime dysfunction. ConclusionA PICO framework of Tai Chi for the health benefits of college students has been constructed using ICF. Tai Chi engaged in by college students are mainly 24 simplified Tai Chi. The frequency of physical activity of Tai Chi is 45 to 90 minutes (60 minutes mostly) a time, 1 to 6 times a week, for 4 to 18 weeks. The physical activities of Tai Chi can benefit in reducing anxiety and depression of college students and improving the quality of sleep.

Evolution and Connotations of "Prohibition"， "Contraindication"， or "Use with Caution" in Chinese Materia Medica / 中国实验方剂学杂志

This study systematically combed and analyzed the use of such terms as "prohibition"， "contraindication"， and "use with caution" in ancient Chinese books on materia medica and prescriptions， Pharmacopoeia of the People's Republic of China（《中华人民共和国药典》）， and teaching materials and monographs of Chinese materia medica by means of hermeneutics， commentariology， textology， and data mining， and explored the historical evolution and conceptual connotations of "prohibition"， "contraindication"， and "use with caution" in Chinese materia medica， so as to provide reference for standardizing their understandings and clinical reasonable medication. The "prohibition"， "contraindication"， and "use with caution" of Chinese materia medica were first proposed in the period of pre-Qin and Han dynasties. "Prohibition" and "contraindication" were separately developed in the Sui， Tang， and Five dynasties and Song， Jin， and Yuan dynasties and have been widely used since the Ming and Qing dynasties. The "use with caution" becomes popular rapidly in modern times and is often present in clinical medication together with "prohibition" and "contraindication". "Prohibition" basically means strictly prohibited and "contraindication" means to avoid as much as possible. The terms "prohibition"， "contraindication"， and "use with caution" have experienced evolution from the pre-Qin period to modern times， and they are used to describe the degree of restriction on drug use（"prohibition" > " contraindication" > "use with caution"）.

Research status of acetabular reconstruction in Crowe type Ⅱ and Ⅲ developmental dysplasia of the hip / 中国骨伤

Developmental dysplasia of the hip (DDH) is a major cause of hip arthritis and ultimately total hip arthroplasty. Due to the dysplastic acetabulum, how to place the acetabular cup becomes a challenge in acetabular reconstruction for such patients. Especially in the acetabula classified as Crowe typeⅡand type Ⅲ, the dislocation of the femoral head causes bone defects above the true acetabulum, which will affect the stability of the acetabular cup when the acetabular reconstruction is performed at the true acetabulum. Many acetabular reconstruction methods such as bone grafting, the use of small acetabular cups, socket medialization technique, and high hip center technique are used to increase the host bone coverage of the cup. However, each method has its own shortcomings that can not be ignored so that there is no unified conclusion on the acetabular reconstruction methods for Crowe typeⅡand type Ⅲ hip dysplasia. This article summarized and evaluated various reconstruction methods in combination with the acetabular morphology of DDH, and put forward the research direction in the future.

Etiological detection and epidemiological analysis of children with influenza-like illness / 中华检验医学杂志

Objective:To analyze the status and epidemiological characteristics of respiratory virus infection in children with influenza-like illness in outpatient department, and to provide evidence for the prevention and treatment of children in this area.Methods:Nasopharyngeal swab samples were collected from children who attended the fever clinic of The Children′s Hospital, Zhejiang University School of Medicine due to influenza-like illness from July 2021 to March 2022, and six common respiratory virus nucleic acids were detected by reverse transcription-polymerase chain reaction (RT-PCR). The general information of the children was collected and grouped by gender and age (0-<6 months, 6-<12 months, 1-3< year-old, 3-<6 year-old , and ≥6 year-old), and the chi-square test was used for statistical analysis between the groups to explore the epidemic pattern of respiratory viruses.Results:A total of 739 cases (45.9%, 739/1 609) of respiratory viruses were detected from children with influenza-like illness, including 651 cases (40.5%, 651/1 609) of simple infection and 88 cases (5.5%, 88/1 609) of multiple infections. Respiratory syncytial virus (RSV) was detected in 18.6% (300/1 609), followed by influenza B virus (FluB) in 11.9% (192/1 609), adenovirus (ADV) in 8.3% (134/1 609), parainfluenza virus type 3 (PIV-3) in 7.6% (123/1 609), parainfluenza virus type 1 (PIV-1) in 4.9% (79/1 609), and influenza A virus (FluA) in 0.4% (6/1 609). Multiple infections including double or triple infections, with 81(92.0%, 81/88) cases of double infection and the most common being ADV+RSV (22.7%, 20/88) and 7 (8.0%, 7/88) cases of triple infection. There was a significant difference in the virus detection rate between the age groups (χ2=17.078, P=0.002), with the highest virus detection rate in the 3-<6 years of age group (49.7%, 286/575). Among the detection of simple infection, FluB had the highest detection rate in the ≥ 6 years of age group (26.6%, 98/369), and RSV and PIV-1 had the highest detection rate in the 3-<6 years of age group (20.0%, 115/575 and 5.9%, 34/575). The total monthly virus detection rate increased from 26.8% (37/138) in July to 63.0% (58/92) in January, and decreased to 46.1% (106/230) and 26.8% (37/138) in February and March. The detection rate of RSV was the highest from August to November, the detection rate of FluB was the highest from December to March, the detection rate of ADV increased in December and January, and the detection rate of PIV-3 increased from October to December; the detection rate of PIV-1 did not fluctuate significantly, and FluA was sporadically detected. Conclusions:RSV is the main respiratory virus in children with influenza-like illness. Most respiratory viruses are present as single infections. Multiple infections are more common in double infections. FluB, RSV and PIV-1 infections showed certain age distribution characteristics, especially in children over 3 years of age. The epidemic characteristics of respiratory virus infection show that the epidemic gradually peaks from summer to autumn and winter, and turns into an epidemic decline in spring. RSV was relatively prevalent in autumn, FluB was prevalent in winter and spring, ADV and PIV-3 were prevalent to varying degrees in winter, PIV-1 continued to circulate at a low level, and FluA did not present epidemic characteristics.

Development of novel-nanobody-based lateral-flow immunochromatographic strip test for rapid detection of recombinant human interferon α2b / 药物分析学报

Recombinant human interferon α2b(rhIFNα2b)is widely used as an antiviral therapy agent for the treatment of hepatitis B and hepatitis C.The current identification test for rhIFNα2b is complex.In this study,an anti-rhIFNα2b nanobody was discovered and used for the development of a rapid lateral flow strip for the identification of rhIFNα2b.RhIFNα2b was used to immunize an alpaca,which established a phage nanobody library.After five steps of enrichment,the nanobody I22,which specifically bound rhIFNα2b,was isolated and inserted into the prokaryotic expression vector pET28a.After subsequent purification,the physicochemical properties of the nanobody were determined.A semiquantitative detection and rapid identification assay of rhIFNα2b was developed using this novel nanobody.To develop a rapid test,the nanobody I22 was coupled with a colloidal gold to produce lateral-flow test strips.The developed rhIFNα2b detection assay had a limit of detection of 1 μg/mL.The isolation of I22 and successful construction of a lateral-flow immunochromatographic test strip demonstrated the feasibility of performing ligand-binding assays on a lateral-flow test strip using recombinant protein products.The principle of this novel assay is generally applicable for the rapid testing of other com-mercial products,with a great potential for routine use in detecting counterfeit recombinant protein products.

Research progression in the pathogenesis of osteoarthritis / 中国骨伤

Osteoarthritis(OA) is one of the most common joint diseases. As Chinese society enters the age of aging, the incidence of OA has been soar year by year, and research on its pathogenesis has been continuously valued by researchers. Studies have found that inflammatory cytokines, mainly interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α), were responsible for the construction of OA inflammatory networks. It was also found that the overexpression of proteases, mainly matrix metalloproteinases(MMPs) and a disintegrin and metalloproteinase with thrombospondin motifs (ADAMTS), was the direct cause of OA cartilage deficiency. What's more, signaling pathways such as stromal cell derived factor-1 (SDF-1) and Wnt, chondrocytic senescence and the senescence-associated secretory phenotype (SASP), chondrocyte apoptosis and autophagy, and estrogen all play significant roles in OA pathogenesis. This paper extensively reviews the research literature relevant to the pathogenesis of OA in recent years, and systematically expounds the pathogenesis of OA from two aspects:molecular level and cell level. At the end of the paper, we discussed and predicted some potential directions in the future clinical diagnosis and treatment of OA.

Evaluation Elements of Clinical 'Prohibition' 'Contraindication'， or 'Use with Caution' in Chinese Medicine Based on Ancient and Modern Literature / 中国实验方剂学杂志

In view of the current controversy in the clinical evaluation of the terms of 'prohibition' 'contraindication'， and 'use with caution'， the present study summarized their evaluation elements to provide references for the classification of 'prohibition' 'contraindication'， and 'use with caution' and clinical rational medication of drugs. Based on the ancient and modern representative traditional Chinese medicine （TCM） literature， such as the records on herbal medicines and prescriptions， medical classics， pharmacopoeia， clinical monographs， and papers， this study proposed the evaluation elements and the underlying ideas of 'prohibition' 'contraindication'， and 'use with caution' around the risks and benefits of medication. The results indicate that the evaluation elements of 'prohibition' 'contraindication'， and 'use with caution' include TCM property，syndrome，symptom， TCM compatibility，dosage，and treatment course. When evaluating 'prohibition' 'contraindication'， and 'use with caution' of TCM under specific conditions of medication，we can determine the properties of prohibited or contraindicated drugs prior to figuring out the differences in 'prohibition' 'contraindication'， and 'use with caution'. It is feasible to evaluate the clinical 'prohibition' 'contraindication'， and 'use with caution' in TCM from Chinese medicine， body， and the clinical medication， which are correlated with each other in the practice implementation.

Human papillomavirus distribution and cervical cancer epidemiological characteristics in rural population of Xinjiang, China / 中华医学杂志(英文版)

BACKGROUND@#Cervical cancer remains a major public health issue for the Uyghur women and other women living mainly in rural areas of Xinjiang. This study aims to investigate the distribution of human papillomavirus (HPV) infection and cervical cancer in rural areas of Xinjiang, China.@*METHODS@#Cervical cancer screening was performed on rural women aged 35 to 64 years from Xinjiang, China in 2017 through gynecological examination, vaginal discharge smear microscopy, cytology, and HPV testing. If necessary, colposcopy and biopsy were performed on women with suspicious or abnormal screening results.@*RESULTS@#Of the 216,754 women screened, 15,518 received HPV testing. The HPV-positive rate was 6.75% (1047/15,518). Compared with the age 35-44 years group, the odds ratios (ORs) of HPV positivity in the age 45-54 years and 55-64 years groups were 1.18 (95% confidence interval [CI]: 1.02-1.37) and 1.84 (95% CI: 1.53-2.21), respectively. Compared with women with primary or lower education level, the ORs for HPV infection rates of women with high school and college education or above were 1.37 (95% CI: 1.09-1.72) and 1.62 (95% CI: 1.23-2.12), respectively. Uyghur women were less likely to have HPV infection than Han women, with an OR (95% CI) of 0.78 (0.61-0.99). The most prevalent HPV types among Xinjiang women were HPV 16 (24.00%), HPV 33 (12.70%), and HPV 52 (11.80%). The detection rate of cervical intraepithelial neoplasia (CIN)2+ was 0.14% and the early diagnosis rate of cervical cancer was 85.91%. The detection rates of vaginitis and cervicitis were 19.28% and 21.32%, respectively.@*CONCLUSIONS@#The HPV infection rate in Xinjiang is low, but the detection rate of cervical cancer and precancerous lesions is higher than the national average level. Cervical cancer is a prominent public health problem in Xinjiang, especially in southern Xinjiang.
