ABSTRACT
ObjectiveIn the treatment of acute gouty arthritis （AGA）， western medicine is mostly used for anti-inflammatory and analgesic purposes to control the blood uric acid level， but some patients are still at risk of poor control and recurrent attacks. Chinese medicinal prescriptions， potent in resisting inflammation and relieving pain， are able to stabilize the blood uric acid level， reduce acute attacks， and improve the clinical efficacy of western medicine. However， there is a lack of evidence to support their use as evidence-based medicine. This study employed network Meta-analysis （NMA） to evaluate the efficacy and safety of common Chinese medicinal prescriptions in the treatment of AGA， aiming to provide evidence-based medical evidence for the clinical use of Chinese medicinal prescriptions in the treatment of AGA. MethodChinese and English databases were searched for prospective cohort studies and randomized controlled trials （RCTs） on Chinese medicinal prescriptions against AGA from database inception to December 1， 2022. Stata software and Review Manager were used for statistical analysis. ResultForty-four papers with 3 564 cases involved were included in the current NMA. In terms of reducing blood uric acid， the cumulative probability results showed that Mahuang Lianyao Chixiaodou Tang showed optimal efficacy （87.60%）. In terms of relieving joint pain， Danggui Niantongtang and Guizhi Shaoyao Zhimutang showed optimal efficacy （92.00% and 82.30%）. In terms of improving erythrocyte sedimentation rate （ESR）， Simiaowan was superior to other prescriptions （87.00%）. In terms of reducing C-reactive protein （CRP）， Simiaowan and Baihutang modified with Guizhitang showed superior efficacy （76.00% and 66.10%）. In terms of safety， except for the basic treatment group， Mahuang Lianyao Chixiaodou Tang had the lowest probability of adverse events， and Danggui Niantongtang had the highest probability of adverse reactions during treatment. According to the results of cluster analysis， Mahuang Lianyao Chixiaodou Tang and Simiaowan are effective and safe. ConclusionAccording to the results of NMA， Chinese medicinal prescriptions can assist in the treatment of AGA and improve the effectiveness of western medicine. For patients with AGA， clinicians can choose Mahuang Lianyao Chixiaodou Tang or Simiaowan as an auxiliary drug for routine western medicine treatment.
ABSTRACT
OBJECTIVE@#To analyze the clinical significance of combined newborn hearing and deafness gene screening in Yuncheng area of Shanxi Province.@*METHODS@#Results of audiological examinations, including transient evoked otoacoustic emission and automatic discriminative auditory brainstem evoked potentials, for 6 723 newborns born in Yuncheng area from January 1, 2021 to December 31, 2021, were retrospectively analyzed. Those who failed one of the tests were considered to have failed the examination. A deafness-related gene testing kit was used to detect 15 hot spot variants of common deafness-associated genes in China including GJB2, SLC26A4, GJB3, and mtDNA12S rRNA. Neonates who had passed the audiological examinations and those who had not were compared using a chi-square test.@*RESULTS@#Among the 6 723 neonates, 363 (5.40%) were found to carry variants. These have included 166 cases (2.47%) with GJB2 gene variants, 136 cases (2.03%) with SLC26A4 gene variants, 26 cases (0.39%) with mitochondrial 12S rRNA gene variants, and 33 cases (0.49%) with GJB3 gene variants. Among the 6 723 neonates, 267 had failed initial hearing screening, among which 244 had accepted a re-examination, for which 14 cases (5.73%) had failed again. This has yielded an approximate prevalence of hearing disorder of 0.21% (14/6 723). Among 230 newborns who had passed the re-examination, 10 (4.34%) were found to have carried a variant. By contrast, 4 out of the 14 neonates (28.57%) who had failed the re-examination had carried a variant, and there was a significant difference between the two groups (P < 0.05).@*CONCLUSION@#Genetic screening can provide an effective supplement to newborn hearing screening, and the combined screening can provide a best model for the prevention of hearing loss, which can enable early detection of deafness risks, targeted prevention measures, and genetic counseling to provide accurate prognosis for the newborns.

【Objective】 To investigate the role and mechanism of dapagliflozin (Dapa), a sodium glucose co-transporter 2 inhibitor, in acute liver injury. 【Methods】 Eight-week-old C57BL6/J mice were given a single intraperitoneal injection of CCl4 to induce acute liver injury. The mice were preventively given 5 mg/kg Dapa by gavage 24 h and 2 h before CCl4 injection, while those in the control group were given an equal volume of solvent gavage. After 24 h, the mice were anesthetized and sacrificed. H&E staining, plasma biochemistry, RT-qPCR, and Western blotting were used to detect the severity of liver injury and the expressions of macrophage-related genes. 【Results】 In the CCl4 group, hepatic infiltration of inflammatory cells increased, and liver and renal functions significantly deteriorated, which was further aggravated by Dapa. CCl4 could promote the expressions of M1 macrophages and fibrosis-related genes in the liver, but reduce those of M2 and antioxidant-related genes, and the latter was further inhibited by Dapa. In addition, the protein expression of arginase 1 decreased and that of SGLT2 increased after Dapa intervention, while NF-κB pathway did not change significantly, suggesting that Dapa might directly affect the energy metabolism homeostasis in the liver and aggravate acute liver injury induced by CCl4. 【Conclusion】 Dapa can exacerbate hepatic and renal damage in acute stage of liver injury, inhibit macrophages M2 polarization, and aggravate oxidative stress and inflammatory injury induced by CCl4.
ABSTRACT
To investigate the relationship between serum C-reactive protein (CRP) levels and work impairment in patients with ankylosing spondylitis (AS) based on real-world evidence. Outpatients with confirmed AS at Chinese PLA General Hospital were recruited consecutively by Smart-phone SpondyloArthritis Management System (SpAMS) from April 2016 to April 2018. The relationship between CRP and work productivity and activity impairment questionnaire (WPAI) were evaluated. Five hundred and fifty-one outpatients with AS in paid employment were recruited. The presenteeism, overall work impairment, and activity impairment rates increased by 1.4% (1.1%, 1.8%), 1.1% (0.5%, 1.6%), and 1.7% (1.3%, 2.1%), respectively, for every 10 mg/L increase in the CRP level (all P value<0.01). However, the CRP level was not associated with absenteeism after adjusting for covariates [0.5%(-0.4%, 1.0%), P>0.05]. There is a significant association between increased serum CRP levels at baseline and the previous 7-day work impairment in patients with AS. Higher CRP levels contribute to worse presenteeism, overall work impairment, and activity impairment rates, which suggests the necessity of monitoring CRP on treatment, and also indicates that anti-inflammatory therapy may be effective for improving work productivity.
ABSTRACT
How to quickly predict an individual's behavioral choices is an important issue in the field of human behavior research. Using noninvasive electroencephalography, we aimed to identify neural markers in the prior outcome-evaluation stage and the current option-assessment stage of the chicken game that predict an individual's behavioral choices in the subsequent decision-output stage. Hierarchical linear modeling-based brain-behavior association analyses revealed that midfrontal theta oscillation in the prior outcome-evaluation stage positively predicted subsequent aggressive choices; also, beta oscillation in the current option-assessment stage positively predicted subsequent cooperative choices. These findings provide electrophysiological evidence for the three-stage theory of decision-making and strengthen the feasibility of predicting an individual's behavioral choices using neural oscillations.

Objective:To investigate the epidemiological characteristics and influencing factors of scoliosis among primary and middle school students in Dali Bai autonomous prefecture.Methods:A total of 176,729 students aged 6-18 years from 380 primary and secondary schools in eight counties of Dali Bai Autonomous Prefecture were screened for spinal health by visual method, Adams forward bend test and scoliometer measuring the angle of trunk rotation from September to November 2021. The angle of trunk rotation ≥5° or visual method retest positive was used as a positive standard to confirm suspected scoliosis population. Demographic data of the screening population including name, gender, age and ethnicity were collected. The average altitude of the community or village committee in the screening area was recorded. Binary logistic regression analysis was used to screen the influencing factors of scoliosis.Results:There were 176,729 people planned to complete the screening. A total of 140,026 people were actually completed screening with completion rate 79.23%. A total of 3,190 (2.28%) suspected scoliosis positive people were detected. The detection rate of female was 2.52%, which was higher than that of male 2.03% (χ 2=37.18, P<0.001). The detection rate of 10-18 years old group was 2.90%, which was higher than that of 6-9 years old group 0.70% (χ 2=620.79, P<0.001). There was a significant difference in the detection rate among different age groups from 6 to 18 years old (χ 2=1,451.00, P<0.001). The detection rate of Han population was 2.67%, which was higher than that of non-Han population 2.15% (χ 2=31.06, P<0.001). In non-Han population, the detection rate of Bai population was 2.07%, which was lower than that of non-Bai population 2.26% (χ 2=4.02, P=0.045). Trend chi-square test showed significant difference in the detection rate of scoliosis among the general population, 10-18 years old population and 6-9 years old population in the altitude <1,500 m, 1,500-1,599 m, 1,600-1,699 m, 1,700-1,799 m, 1,800-1,899 m, 1,900-1,999 m, 2,000-2,099 m, 2,100-2,199 m, 2,200-2,299 m and ≥2,300 m groups (χ 2=249.02, 195.64, 24.46, P<0.05). Binary logistic regression analysis showed that the risk of scoliosis was lower in males than that in females ( OR=0.82, P<0.001). The risk of scoliosis was increased in 10-18 years old compared with that in 6-9 years old ( OR=0.12, P<0.001). The risk of scoliosis was low in Bai population compared with that in Han populations ( OR=0.75, P<0.001). The altitude ≥2,000 m was a risk factor ( OR=1.52, P<0.001). Conclusion:The detection rate of suspected scoliosis in primary and middle school students in Dali Bai Autonomous Prefecture was 2.28%. Female, aged 10-18 years, Han populations, and residence in altitude ≥2,000 m might be the risk factors for scoliosis.
ABSTRACT
BACKGROUND@#Concerns exist regarding the potential development of tuberculosis in patients with rheumatoid arthritis (RA) treated with biological and targeted drugs. We assessed systematically whether biological therapy increased the risk of tuberculosis in patients with RA by meta-analysis of randomized controlled trials (RCTs).@*METHODS@#A systematic literature search was conducted in PubMed, Embase, the Cochrane Library, and China Biology Medicine disc for RCTs evaluating biological therapy in patients with RA from inception through August 2021. Traditional meta-analysis and network meta-analysis were performed to compare the risk of tuberculosis for each biologics class in patients with RA. Peto odds ratio (Peto OR) and its 95% confidence interval (CI) were calculated as the primary effect measure.@*RESULTS@#In total, 39 studies with 20,354 patients were included in this meta-analysis, and 82 patients developed tuberculosis. The risk of tuberculosis was increased in patients treated with biologics compared with non-biologics (Peto OR: 3.86, 95% CI: 2.36-6.32, P < 0.001). Also, tumor necrosis factor-α (TNF-α) inhibitors had a higher probability of developing tuberculosis than placebo (Peto OR: 3.98, 95% CI: 2.30-6.88, P < 0.001). However, network meta-analysis demonstrated that there was no significant difference in the risk of tuberculosis for each biologics class in patients with RA. Noticeably, tuberculosis was significantly more common in patients treated with a high dose compared with patients receiving a low dose of tofacitinib (Peto OR: 7.39, 95% CI: 2.00-27.31, P = 0.003).@*CONCLUSION@#This meta-analysis demonstrates the evidence of an elevated risk of tuberculosis in patients with RA treated with TNF-α inhibitors, and a dose-dependent elevated risk of tuberculosis in patients treated with tofacitinib.

Objective:To evaluate the efficacy and safety of modified Atkins diet (MAD) in treating global growth retardation (GDD).Methods:A prospective multicenter clinical controlled study was conducted.The children were included from 8 departments of children′s rehabilitation in Henan Province from July 2017 to October 2017.A total of 154 children who met the inclusion criteria were randomly assigned into the routine treatment group (88 cases) and MAD therapy group (66 cases). A total of 62 children in MAD therapy group and 59 children in routine treatment group completed the study for 15 months.The routine treatment group was provided comprehensive rehabilitation training, and the MAD therapy group was given MAD treatment on the basis of rehabilitation training.Two-way repeated-measures ANOVA was used to compare the differences among datas at different time points. Results:After 3 months, there were significant differences in the scores of the Chinese Version of Urban Infant-Toddler Social and Emotional Assessment (CITSEA)/Achenbach Children′s Behavior Scale (CBCL) between the 2 groups (all P<0.05). Significant improvement was seen in the MAD group.After 6 months, the MAD therapy group had significantly higher scores on the Gesell Developmental Scale for language and social behavior than the routine treatment group (all P<0.05). After 9 months, the scores of the children in the MAD therapy group were better than those in the routine treatment group in the Gesell Developmental Scale adaptive energy area and the infant-junior high school student social life scale (S-M scale), and the differences were statistically significant (all P<0.05). After 15 months, the fine motor in the MAD therapy group was better than that in the routine treatment group ( P<0.05). At the early stage of MAD therapy, 28 patients showed mild adverse reactions that were reversed after symptomatic treatment.No severe adverse reactions were observed. Conclusions:MAD therapy can improve the neuro-development, emotional and social behaviors, and adaptive behaviors with no severe adverse effects.
ABSTRACT
Cervical cancer, a common malignant tumor in female reproductive system, seriously threatens women's life and health. The standard surgery for early cervical cancer is radical hysterectomy + pelvic lymphadenectomy±para-aortic lymph node sampling. Lymph node metastasis is an independent risk factor for the prognosis of cervical cancer patients. Several researches showed that the incident of lymph node metastasis in early cervical cancer was approximately 20%. Giving the complications and sequelae of systematic lymph node resection, its application in early cervical cancer is still doubted. The sentinel lymph node, where lymph node metastasis firstly occurs, attracts much attention in the surgical treatment of malignant tumors. Hence, sentinel lymph node biopsy (SLNB) came into being. Recent studies have indicated that SLNB is safe and feasible for early cervical cancer and SLNB is recommended to patients with early cervical cancer. This article will introduce the application of SLNB in cervical cancer in the recent years and discuss its clinical value and related challenges.
ABSTRACT
Objective:To study the early effects of intact-umbilical cord milking (I-UCM) and cut-umbilical cord milking (C-UCM) for the prevention of anemia of prematurity in preterm infants.Method:From January 2019 to October 2019, C-section delivered infants with gestational age <34 weeks were randomly assigned into I-UCM group and C-UCM group. Hematological parameters at different timepoints after birth, iron status, incidence of anemia within 7 d after birth, blood transfusions, transcutaneous bilirubin levels and the total duration of phototherapy were collected and analyzed.Result:A total of 60 cases were enrolled, including 30 in I-UCM group and 30 in C-UCM group. I-UCM group had significant higher levels of hemoglobin (Hb), hematocrit (Hct) and serum iron on admission ( P<0.05). Comparing with C-UCM group, Hb and Hct were significantly higher in I-UCM group at 7 d and 14 d after birth ( P<0.05). Lower prevalence of anemia within 1 week [3.3% (1/30) vs. 33.3% (10/30), P<0.05] and less blood transfusions during hospitalization [13.3% (4/30) vs. 56.7% (17/30)] were noted in I-UCM group. No statistically significant differences existed between the two groups in phototherapy duration and the peak bilirubin levels ( P>0.05). Conclusion:I-UCM can provide more placental transfusion at birth to increase Hb levels and iron storage to prevent and reduce anemia in preterm infants.
ABSTRACT
Exploring neural markers that predict trust behavior may help us to identify the cognitive process underlying trust decisions and to develop a new approach to promote interpersonal trust. It remains unknown how trust behavior may be predicted early in the decision process. We used electrophysiology to sample the brain activity while participants played the role of trustor in an iterative trust game. The results showed that during the trust generation stage, the trust condition led to higher frontocentral beta band activity related to cognitive inhibition compared to the distrust condition (item level). Moreover, individuals with higher frontocentral beta band activity were more likely to perform trust choices at the single-trial level (individual level). Furthermore, after receiving reciprocity feedback on trial
ABSTRACT
Objective@#To analyze the clinical characteristics of patients with ankylosing spondylitis (AS) with inflammation bowel disease (IBD).@*Methods@#AS patients fulfilling the 1984 modified New York diagnostic criteria were recruited in Chinese AS Prospective Imaging Cohort (CASPIC) consecutively from April 2016 to June 2017 in Chinese People′s Liberation Army General Hospital by using smart management system for spondyloarthritis (SpAMS). The diagnosis of IBD was confirmed by tissue pathology via ileocolonoscopy. Demographic, clinical and biochemical data were collected.@*Results@#In total, 893 patients with AS were recruited with the mean age 30.8 years. The majority were men (739, 82.8%). There were 64 (7.2%) patients concomitant with IBD. The mean age [(34.5±7.5) years vs. (30.5±8.8) years, P<0.001] was older and the disease duration [(10.8±6.9) years vs. (8.1±5.9) years, P=0.001] was longer in patients with IBD than patients without. Compared with patients without IBD, patients with IBD had more frequent involvement of the cervical spine [(21.9% (14/64) vs. 10.5% (87/829), P=0.006) and thoracic spine [29.7% (19/64) vs. 12.3% (102/829), P<0.001]. Uveitis [28.1% (18/64) vs. 16.4% (136/829), P=0.017] and psoriasis [7.8% (5/64) vs. 2.3% (19/829), P=0.009] were also more common in patients concomitant with IBD. In addition, patients with IBD had significantly higher scores in BASDAI (3.3±2.1 vs. 2.4±1.8, P<0.001), BASFI [2.2 (1.0,3.3) vs. 1.1(0.2,2.4), P<0.001)] and ASAS HI (7.1±4.3 vs. 5.3±3.7, P= 0.001) than patients without IBD.@*Conclusions@#Compared with patients without IBD, AS patients concomitant with IBD have more severe disease activity and organ dysfunction. Furthermore, the uveitis and psoriasis are more frequently accompanied in AS patients with IBD.

ABSTRACT
Objective:To explore the role of infliximab (IFX) in the repairation of intestinal mucosal barrier in Crohn′s disease (CD).Methods:From January 2018 to October 2019, in Shanghai Tenth People′s Hospital, 382 CD patients were selected. All the patients were treated with IFX. And 103 individuals who underwent colonoscopy were selected as healthy control group. The general clinical data, fasting blood samples and intestinal mucosa tissue samples of CD patients and healthy controls were collected. The body mass index (BMI), hemoglobin, albumin, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and relative inflammation factors, including tumor necrosis factor (TNF)-α, interferon (IFN)-γ, interleukin (IL)-1, IL-2, IL-6, IL-8, IL-10 and IL-17A, and their mRNA expression levels were detected. Crohn′s disease activity index (CDAI) and simplified endoscopic score for Crohn′s disease (SES-CD) were used to evaluate the disease activity of CD patients. The expression levels of occudin, claudin-1, zonula occluden-1 (ZO-1) and junctional adhesion molecule-A (JAM-A) were measured by Western blotting. The intestinal mucosal epithelial cells were observed by transmission electron microscope. T test was used for statistical analysis. Results:Before treatment, BMI, and hemoglobin and albumin levels of CD patients were all lower than those of healthy control group ((18.3±1.8) kg/m 2 vs. (20.2±1.2) kg/m 2, (95.3±8.4) g/L vs. (129.2±5.7) g/L, (33.2±5.4) g/L vs. (50.3±3.2) g/L), and the differences were statistically significant ( t=3.457, 5.342 and 2.674, all P<0.05). After treatment the BMI and hemoglobin levels of CD patients were higher than those before treatment ((19.5±2.1) kg/m 2 vs. (18.3±1.8) kg/m 2, (117.2±10.3) g/L vs. (95.3±8.4) g/L), and the CRP level, CDAI score and SES-CD score were lower than those before treatment ((16.3±2.3) mg/L vs. (47.2±9.3) mg/L, 113.2±12.5 vs. 245.2±23.5, 5.0±2.1 vs. 10.0±4.3), and the differences were statistically significant ( t=2.090, 2.339, 2.432, 6.345 and 5.234, all P<0.05). The expression levels of TNF-α, IFN-γ, IL-2, IL-6, IL-8, IL-17A and their mRNA levels of healthy control group were lower than those of CD patients before treatment ((1.1±0.4) ng/L vs.(158.2±38.3) ng/L, (3.2±0.8) ng/L vs. (28.3±13.4) ng/L, (2.7±1.3) ng/L vs. (3.3±2.4) ng/L, (5.2±0.3) ng/L vs. (16.3±7.4) ng/L, (16.3±6.3) ng/L vs. (18.9±10.2) ng/L, (10.5±2.3) ng/L vs. (38.5±11.2) ng/L; 1.00±0.00 vs. 4.68±0.34, 7.83±0.32, 1.25±0.46, 8.36±0.44, 2.01±0.89 and 6.83±0.53, respectively), and the differences were statistically significant ( t=2.345, 6.456, 3.008, 4.009, 7.045, 10.223, 8.345, 11.235, 1.114, 12.334, 5.304 and 5.678, all P<0.05). After treatment the TNF-α, IFN-γ, IL-2, IL-6, IL-8, IL-17A expression levels and their mRNA levels of CD patients were lower than those before treatment ((106.4±29.9) ng/L vs. (158.2±38.3) ng/L, (25.7±10.8) ng/L vs. (28.3±13.4) ng/L, (2.9±1.7) ng/L vs. (3.3±2.4) ng/L, (15.4±4.2) ng/L vs. (16.3±7.4) ng/L, (17.2±8.7) ng/L vs. (18.9±10.2) ng/L, (29.9±12.7) ng/L vs. (38.5±11.2) ng/L, 2.45±0.21 vs. 4.68±0.34, 3.75±0.18 vs. 7.83±0.32, 1.09±0.22 vs. 1.25±0.46, 3.78±0.21 vs. 8.36±0.44, 1.67±0.33 vs. 2.01±0.89, 2.96±0.11 vs. 6.83±0.53), and the differences were statistically significant ( t=9.345, 2.456, 2.334, 2.090, 3.009, 8.345, 4.567, 6.445, 2.046, 7.774, 3.008 and 8.867, all P<0.05). The results of Western blotting showed that the expression levels of occudin, claudin-1, ZO-1 and JAM-A in the intestinal mucosa of CD patients before treatment were lower than those of the healthy control group (0.21±0.03 vs. 1.00±0.02, 0.17±0.07 vs. 1.00±0.01, 0.16±0.06 vs. 1.00±0.04, 0.26±0.08 vs. 1.03±0.04). After treatment the expression levels of occudin, claudin-1, ZO-1 and JAM- A mRNA in the intestinal mucosa of CD patients were higher than those before treatment (0.77±0.08 vs. 0.21±0.03, 0.69±0.08 vs. 0.17±0.07, 0.78±0.09 vs. 0.16 ±0.06, 0.72±0.07 vs. 0.26±0.08), and the differences were statistically significant ( t=4.567, 6.346, 5.557, 8.456, 9.678, 8.671, 10.456 and 7.456, all P<0.05). Conclusions:IFX can effectively relieve the disease activity and improve the nutritional status of CD patients. IFX maintains the expression of intestinal epithelial tight junction protein by reducing inflammatory response, and repairs the intestinal mucosal barrier of CD patients.
ABSTRACT
Objective:To observe the clinical efficacy and side effects of injecting different doses of botulinum toxin type A (BTX-A) into children with spastic cerebral palsy (CP) and tiptoe deformity.Methods:A total of 107 children with tiptoe deformity resulting from CP were divided into group A ( n=35), group B ( n=36) and group C ( n=36) using a random number table. Group A received 3u/kg injections of BTX-A, group B received 4u/kg injections and group C received 5u/kg. The injections were guided by color Doppler ultrasound and followed by 4 courses of rehabilitation therapy. Before and 1, 3 and 6 months after the treatment, the modified Tardieu scale (MTS) was used to assess gastrocnemius spasms, while sections D and E of gross motor function scale 88 (GMFM-88) and the pediatric balance scale (PBS) were used to evaluate motor functioning and balance. Any side effects were also observed. Results:After the treatment, improvement was observed in all of the measurements, though there were no significant differences in the degree of improvement nor in the incidence of side effects among the three groups.Conclusions:There is no significant difference in clinical efficacy or side effects involved in using different doses of BTX-A to treat tiptoe deformity in children with spastic cerebral palsy. The recommended dosage is therefore 3u/kg.
ABSTRACT
Objective In order to assess the structure damage of hip joint in ankylosing spondylitis (AS), a new radiograph-based scoring method was developed according to the radiological characteristics of hip involvement in AS, as well referring to prior existing scoring indexes. Methods A new scoring method consti-tuted of erosion, sclerosis and joint space narrowing was developed, pelvis anterior-posterior plain films acquired from patients with AS at baseline and follow-up were collected and assessed by two physicians who were trained in image reading by radiologists. All films were scored independently and blindly. Intra- and inter-reader reliability were assessed by intra-class correlation coefficient (ICC), the feasibility of this new scoring method was assessed by the mean time acquired to score a plain (two hips), its ability to detect the change of structure damage was assessed by the comparison of score differences between baseline and different follow-ups. The date were analyzed by paired-t test or nonparametric tests. Analysis of Variance (ANOVA) or nonparametric tests were utilized for the comparison of means of quantitative variables among the three groups, while Chi-square test for rates of categorical variables. Results No statistically significant differences existed in demographic data and suspected risk factors among the three groups at baseline (P>0.05). Intra-observer reliability was good (0.84 and 0.89), as well as the inter-observer reliability (0.72), the mean time needed to score was (33 ±10) seconds. Score changes were not statistically significant in the groups with follow-up duration of 1-2 and 3-4 years, but in the group of over 5 years, baseline/final scores assessed by the two observers were (6.0±2.7/7.5±3.7) and (5.6±2.1/7.1±3.6), respectively, both changes were statistically significant (t=2.86, Z=-2.99; P<0.01). Conclusion This new method is not only reproducible and easy to operate in clinic practice, but also can tell the changes of hip joint structure damage in the interval of over 5 years, further validation is requeired to demonstrate its discriminability in large populations.
ABSTRACT
Objective To compare the clinical results of two surgery for medial compartment osteoarthritis of theknee.Methods We choosed 49 patients with medial compartment osteoarthritis knee joint who were accessed to the hospital in the corresponding standards from January 2013 to January 2016.All the patients were divided into two groups according to the different surgery:unicompartmental knee athroplasty U group(21 patients)and proximal fibular osteotomy F group(28 patients).We recorded and compared the two groups with the operative incisionlength,bloodloss,operationtime,hospitalization time,totalcost during hospitalization,HSS and VAS.Results After oper ating 3 months,the HSS knee score of the two groups increased significantly and the VAS decreased significantly(P ＜ 0.05).While compared between the two groups in the same period,there were no significant differences in HSS and VAS(P ＞ 0.05).The operative incision length,the amount of blood loss,operation time,hospitalization time,total cost during hospitalization in F group were significantly better than those in U group,and the difference was statistically significant (P ＜ 0.05).Conclusion Proximal fibula osteotomy has the similar effect with the UKA and has the advantages of less trauma,less blood loss,low cost,shorter duration of operation and shorter hospitalization time etc.It has a good prospect.
ABSTRACT
Aim To investigate the inhibitory effect of Bupleurum chinense-Scutellaria baicalensis decoction(CQ)on activation of rat HSC induced by CCl4 and the mechanism.Methods Cells in logarithmic growth phase were cultured in culture medium without FBS for 24 h.After disassociated using 0.25％EDTA-trypsin,the cells were seeded into respective plates at the density of 1.5×109· L-1 and cultured overnight.The cells were divided into the following groups:control group(no treatment),model group(treated with 6 mmol·L-1 CCl4 for 24 h),CQ groups(pretreated with 6 mmol·L-1 CCl4 for 24 h and 400,500,600 mg·L-1 CQ for 24 h).Concentrations of hyaluronidase(HA),laminin(LN),procollagen Ⅲ(PCⅢ),collagen type Ⅳ(Ⅳ-C)were assayed by ELISA kits.Gene expressions of Toll-like receptor 4(TLR4)and NF-κB were examined by RT-PCR analysis.Protein expression of TLR4 and NF-κB was examined by Western blot.Results CQ could significantly inhibit cell proliferation induced by CCl4.Furthermore,CQ at 600 mg·L-1 significantly downregulated gene and protein expressions of TLR4 and NF-κB.And CQ reduced the secretion of HA,LN,PCⅢ,Ⅳ-C.Further studies disclosed that the TLR4 inhibitor TAK-242 and NF-κB inhibitor BAY 11-7082 could significantly inhibit the gene and protein expressions of NF-κB,but could not change gene and protein expression of TLR4,and reduced the secretion of HA,LN,PCⅢ,Ⅳ-C.Conclusion CQ could inhibit inflammatory responses in HSC induced by CCl4 probably by inhibiting the transcription activity and protein expression of TLR4-NF-κB,which indicates its possible therapeutic effect on liver fibrosis.
ABSTRACT
Porcine deltacoronavirus (PDCoV) has been recently recognized as an emerging viral pathogen that causes diarrhea in newborn piglets. A total of 254 small intestinal or fecal samples collected from 10 provinces including Henan, Hunan, Zhejiang, Jiangxi, Anhui, Hebei, Heilongjiang, Jiangsu, Shandong and Shanghai between 2014 and 2015, were screened by quantitative RT-PCR targeting the viral M gene. Eleven PDCoV positive samples were identified with a total positive rate of 4.33%. An indirect enzyme-linked immunosorbent assay (ELISA) was developed based on the recombinant S1 protein of PDCoV. This assay was used to test 609 serum samples of pigs with diarrhea symptoms collected from 10 provinces between 2015 and 2016. The positive rate of PDCoV antibody was 44.17% (269/609). The two methods can be used to monitor the PDCoV epidemiology in the levels of PDCoV specific RNA or antibody, helping better prevent and control PDCoV.
