OBJECTIVE@#To explore influence of external factors of wind, cold and dampness on clinical symptoms in knee osteoarthritis (KOA) patients with different constitutions of traditional Chinese medicine.@*METHODS@#A cross-sectional stratified study was performed to select 108 patients with GradeⅡKOA in Kellgren & Lawrence (K-L) classification, including 22 males and 86 females, aged from 47 to 75 years old with an average of (60.7±6.0) years old;body mass index(BMI) ranged from 17.87 to 31.22 kg·m-2 with an average of (23.80±2.86) kg·m-2. According to Classification and Judgment of TCM Physique (ZYYXH/T157-2009), the types of TCM physique were determined and divided into 4 layers according to the deficiency and actual physique. Among them, there were 24 patients without biased physique, 12 males and 12 females, aged from 51 to 73 years old with an average of(62.8±6.0) years old, BMI ranged from 17.87 to 31.14 kg·m-2 with an average of (24.32±3.25) kg·m-2;there were 46 patients with virtual bias constitution, including 7 males and 39 females, aged from 47 to 70 years old with an average of (60.0±5.8) years old, BMI ranged from 19.38 to 31.22 kg·m-2 with an average of(23.42±2.97) kg·m-2;There were 26 patients with solid bias constitution, including 2 males and 24 females, aged from 48 to 75 years old with an average of (60.4±5.8) years old, BMI ranged from 21.16 to 30.76 kg·m-2 with an average of (24.15±2.33) kg·m-2;there were 9 patients with special constitution, 1 male and 8 female, aged from 53 to 75 years old with an average of (59.8±7.5) years old, BMI ranged from 19.26 to 26.67 kg·m-2 with an average of (23.79±2.49) kg·m-2. Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) was used to evaluate severity of clinical symptoms. The wind-cold-dampness external factor score was calculated through the questionnaire of wind-cold-dampness syndrome scale to evaluate degree of influence of wind-cold-dampness external factor. Pearson correlation analysis and partial correlation analysis were used to calculate the correlation coefficient between severity of external factors affecting wind, cold and dampness and severity of clinical symptoms in patients with different TCM constitution stratification.@*RESULTS@#There was no statistical significance between total score of wind-cold-dampness and WOMAC score in patients with no biased constitution and special condition. Total wind-cold-dampness score of patients with virtual biased constitution was positively correlated with WOMAC stiffness score (r=0.327, P=0.032), and total wind-cold-dampness score of patients with solid biased constitution was positively correlated with WOMAC pain score (r=0.561, P=0.005) and WOMAC overall score (r=0.446, P=0.033). After further adjusting for the interaction of external factors of wind-cold-dampness, there was no statistical significance between wind-cold-dampness scores and WOMAC scores in patients with solid biased constitution. The score of dampness and pathogenic factors was positively correlated with WOMAC stiffness score (r=0.414, P=0.007).@*CONCLUSION@#The external factors of wind-cold dampness have different effects on the clinical symptoms of KOA patients with different TCM constitutions. Compared with other constitutions, the rigid symptoms of patients with asthenic biased constitutions are more susceptible to dampness pathogenic factors.

This study systematically reviewed the clinical efficacy of acupuncture for lumbar myofascial pain syndrome. The randomized controlled trials (RCTs) regarding acupuncture for lumbar myofascial pain syndrome were searched in PubMed, Cochrane Library, Web of Science, EMbase, Scopus, China national knowledge infrastructure (CNKI), Wanfang database, VIP database, and China biomedical literature service system (SinoMed) from database inception until August 1st, 2022. The Cochrane's risk of bias assessment tool was used to assess the risk of bias in all included studies, and Review Manager 5.3 software was used for statistical analysis of the extracted data. As a result, 12 RCTs, involving 1 087 patients with lumbar myofascial pain syndrome, were ultimately included. The Meta-analysis results showed that the visual analog scale (VAS) score of pain in the observation group was lower than those in the oral non-steroidal anti-inflammatory medication control [SMD=-1.67, 95%CI (-2.44, -0.90), Z=4.26, P<0.000 1] and other treatment control [low-frequency electrical stimulation, tuina, electromagnetic wave irradiation combined with piroxicam gel, SMD=-1.98, 95%CI (-2.48, -1.48), Z=7.74, P<0.000 01]. The pain rating index (PRI) score in the observation group was lower than those in the lidocaine injection control [MD=-2.17, 95%CI (-3.41, -0.93), Z=3.44, P=0.000 6] and other treatment control [low-frequency electrical stimulation, tuina, MD=-5.75, 95%CI (-9.97, -1.53), Z=2.67, P=0.008]. The present pain intensity (PPI) score in the observation group was lower than that in other treatment control [low-frequency electrical stimulation, tuina, MD=-1.04, 95%CI (-1.55, -0.53), Z=4.01, P<0.000 1]. In conclusion, compared with oral non-steroidal anti-inflammatory medication, low-frequency electrical stimulation, tuina, and electromagnetic wave irradiation combined with piroxicam gel, acupuncture is more effective in reducing pain in patients with lumbar myofascial pain syndrome; acupuncture also exhibites advantage over lidocaine injection in improving PRI score and showed better outcomes over tuina and low-frequency electrical stimulation in improving PRI and PPI scores.

Résumé
Dysarthria is a group of nerological speech disorder, which occurred in about 20%-30% after stroke, or 10%-60% after traumatic brain injury. The assessment of speech intelligibility is a necessary part of the evaluation of dysarthria, which can be used to communicate the patients' condition with their relations, and also in treatment planning, evaluating the communication performance and the treatment effects. The methods used to assess intelligibility can be divided into two groups: scaling methods and item identification methods. They are also divided into non-standard and standard methods based on whether a standard assessment or not. Scaling methods include interval scales, Direct Magnitude Estimation (DME), Speech Sample Pairs Scaling, Percentage Estimates, and Visual Analogue Scale (VAS), etc. The item identification methods mainly include: Word Intelligibility Test, Chinese Speech Intelligibility Test, Chinese Speech Intelligibility Test Character List, Chinese Articulation Ability Test Word List, Sentence Intelligibility Test, Assessment of Intelligibility in Dysarthric Speakers (AIDS) and Speech Intelligibility Test (SIT) software. Among them, AIDS and SIT softwares are comprehensively standardized assessments. There are few methods can be used in China. The literatures on intelligibility assessment in the past ten years were reviewed.

Résumé
Zearalenone (ZEA) is a nonsteroidal estrogen-like mycotoxin widely distributed in maize, wheat, rice and other cereals with its derivants. It also presents in meat or dairy products or even in the aquatic ecosystem via rain, and thus can affect human health. ZEA affects the body function in various ways. On the one hand, it can disturb the synthesis of estrogen and its combination with the receptor, influence the reproductive ability via the estrogen signaling pathway, and cause the dysfunction of the reproductive systems. On the other hand, it can disturb the synthesis of DNA and proteins and result in lipid peroxidation and cytotoxicity by inducing the apoptosis of germ cells. It is known that exposure to different doses of ZEA can affect the female reproductive system by increasing the apoptosis of germ cells and inducing germ cell prematurity, sexual precocity, endocrine disorder, reproductive cycle disorder, and so on. But studies of its influence on the male reproductive system are relatively rare, especially about its unique male-related action mechanisms. This review presents an overview of the studies on the mechanisms of ZEA affecting male fertility and the phenotype changes in the male reproductive system after exposure to ZEA, hoping to provide some new ideas for the protection of human fertility.

Data of studying was analyzed by frequency statistics and Hierachical cluster analysis.</p><p><b>RESULTS</b>The distribution of tender points in the knee osteoarthritis was mainly in the interior region and anterior area such as in apex of patella, adductor tubercle and et al. According to the results of hierachical cluster analysis, the tender points could be divided into two categories the first cluster was in the interior region of knee, the second cluster was in the lateral region.</p><p><b>CONCLUSION</b>The findings demonstrated that cluster analysis statistical method can be used for classification of the distribution of tender points. The distribution features of tender points in knee osteoarthritis are related to the anatomic site in knee.</p>

<p><b>OBJECTIVE</b>To explore the diagnostic value of whole-organ magnetic resonance imaging score (WORMS) in knee osteoarthritis (KOA).</p><p><b>METHODS</b>From November 2009 to January 2011,70 patients with KOA combined with knee effusion among outpatient and inpatient were analyzed retrospectively. Among the patients, 12 patients were male, 58 patients were female,ranging in age from 46 to 75 years,with a mean age of (59.66 +/- 9.93) years. The clinical symptoms were evaluated by WOMAC, the imaging of KOA was assessed by K-L score and WORMS, and COMP and CTX- II were measured respectively by ELISA. The correlation analyses and multiple linear regression analysis were studied to determine associations among biomarkers, clinical variables and radiographic findings of knee joints.</p><p><b>RESULTS</b>The average scores of WOMAC and WORMS were (57.50 +/- 8.20) and (64.54 +/- 16.45) respectively. The median of CTX- II nd COMP were 2.42 ng/ml and 4.56 ng/ml respectively. Grouped by less than the lowest quartile and more than the highest quartile of WORMS, COMP was significantly different (Z=2.04, P=0.039), but there was no significant difference in CTX-II (Z=0.79, P=0.427). WORMS were positively correlated with WOMAC and K-L score (r=0.777, P<0.01; r=0.716, P<0.01; respectively); WOMAC was also positively correlated with K-L score (r=0.692, P<0.01). WORMS's cartilage, osteophytes and synovitis were positively correlated with WOMAC, K-L score and COMP respectively (r=0.771, P<0.01; r=0.509, P<0.01; r=0.917, P<0.01). It was determined by stepwise regression that the KOA was mainly affected by WORMS, K-L score (P=0.015, P=0.025 respectively) when WOMAC as a dependent variable, age, gender, K-L score, WORMS, COMP and CTX- II as independent variables (F=20.327, P<0.01).</p><p><b>CONCLUSION</b>WORMS has a better reference value for diagnosis of KOA. The expression of COMP is high in the synovial fluid when WORMS at the high point. The clinical symptoms of knee osteoarthritis are mainly affected by WORMS and K-L score.</p>
