ABSTRACT
Objective:To investigate the effects of biologics on psychological status and quality of life in patients with inflammatory bowel disease (IBD).Methods:A cross-sectional survey was conducted in 42 hospitals in 22 provinces (autonomous regions and municipalities directly under the central government) from September 2021 to May 2022. General clinical information and the use of biologics were obtained from adult patients diagnosed with IBD who voluntarily participated in the study. Psychological status was evaluated using the Generalized Anxiety Disorder (GAD-7), Patient Health Questionnaire-9 (PHQ-9), Pittsburgh Sleep Quality Index (PSQI), and Inflammatory Bowel Disease Questionnaire (IBDQ) assessment tools. Counts were analyzed via the Chi-square test, and datasets that were not normally distributed were analyzed via nonparametric tests. P<0.05 was considered statistically significant. Results:A total of 2 478 valid questionnaires were collected. The GAD-7 score of the biologics group was significantly lower than that of the non-use group [6 (2, 9) vs. 7 (3, 10), Z=-3.49, P<0.001]. IBDQ scores [183 (158, 204) vs. 178 (152, 198), Z=-4.11, P<0.001], intestinal symptom scores [61 (52, 67) vs. 58 (49, 65), Z=-5.41, P<0.001], systemic symptom scores [28 (24, 32) vs. 27 (23, 31), Z=-2.37, P=0.018], emotional ability scores [69 (58, 77) vs. 67 (56, 75), Z=-3.58, P<0.001] and social ability scores [26 (22, 29) vs. 25 (22, 29), Z=-2.52, P=0.012] in the biologics group were significantly higher than in the non-use group. GAD-7 scores [5 (2, 9) vs. 6 (3, 10), Z=-3.50, P<0.001] and PSQI scores [6 (4, 9) vs. 6 (4, 9), Z=-2.55, P=0.011] were significantly lower in the group using infliximab than in the group not using it. IBDQ scores were significantly higher in patients using vedolizumab than in those not using it [186 (159, 205) vs. 181 (155, 201), Z=-2.32, P=0.021] and were also significantly higher in the group treated with adalimumab than in the group not treated with adalimumab [187 (159, 209) vs. 181 (155, 201), Z=-2.16, P=0.030]. However, ustekinumab had no significant effect on any of the scores. Conclusion:The use of biologics is strongly associated with improvements in anxiety status and quality of life in IBD patients.
ABSTRACT
Objective:To investigate the psychology status and quality of life in patients with inflammatory bowel disease(IBD) in China, and to analyze the influencing factors.Methods:From September 2021 to May 2022, 42 hospitals in 22 provinces(autonomous regions and municipalities directly under the central government) in China, the clinical data of 2 478 IBD patients were collected, which included age, gender, weight, first visit or not, disease activity, disease course, main clinical manifestations(diarrhea, abdominal pain, hematochezia, extraintestinal manifestations), complications, treatment medication(5-aminosalicylic acid, glucocorticoids, immunosuppressive agents, and biological agents), and whether to have surgery. Anxiety, depression, sleep quality and quality of life of IBD patients were evaluated by generalized anxiety disorder-7 items, patient health questionnaire-9 items, Pittsburgh sleep quality index and inflammatory bowel disease questionnaire, and the related influencing factors were analyzed. Univariate analysis and multiple linear regression analysis were used for statistical analysis.Results:The average age of 2 478 IBD patients was 37.96 years old, and male counted for 62.43%(1 547/2 478). There were 61.82%(1 532/2 478) of the IBD patients in the active stage of disease, mostly mild or moderate(588 and 734 cases). There were 60.61%(1 502/2 478) of the IBD patients with different degrees of anxiety, 58.35%(1 446/2 478) of the IBD patients with different degrees of depression, and 48.87%(1 211/2 478) of the IBD patients had different degrees of sleep problems. The results of multiple linear regression analysis indicated that female, higher level of disease activity and longer disease course were independent risk factors of anxiety, depression and sleep quality in the IBD patients(unstandardized regression coefficient(95% confidence interval) 1.08(0.65 to 1.50), 0.45(0.23 to 0.68), 0.19(0.02 to 0.36), 0.83(0.33 to 1.32), 0.62(0.36 to 0.88), 0.28(0.08 to 0.47), 0.47(0.16 to 0.77), 0.39(0.23 to 0.55), 0.14(0.02 to 0.26); P<0.001, <0.001, =0.025 , =0.001, <0.001, =0.005, =0.003, <0.001, =0.027). The usage of biological agents was an independent protective factor of anxiety(unstandardized regression coefficient(95% confidence interval) -0.67(-1.17 to -0.17), P=0.008), and older age was an independent risk factor of sleep quality(unstandardized regression coefficient(95% confidence interval) 0.35(0.09 to 0.61), P=0.008). Higher level of disease activity, symptoms of diarrhea, abdominal pain, presence of extraintestinal manifestations, usage of 5-aminosalicylic acid and glucocorticoid, and with surgical treatment were independent risk factors of quality of life(unstandardized regression coefficient(95% confidence interval) -11.00(-12.24 to -9.76), -2.90(-5.26 to -0.55), -3.93(-6.25 to -1.61), -5.79(-9.87 to -1.71), -4.78(-7.79 to -1.76), -7.71(-11.07 to -4.35), -4.37(-8.00 to -0.73); P<0.001, =0.016, =0.001, =0.005 , =0.002, <0.001, =0.019), while the usage of biological agents was an independent protective factor of quality of life (unstandardized regression coefficient(95% confidence interval) 4.72(1.97 to 7.48), P=0.001). Conclusion:IBD patients generally have different degrees of anxiety, depression and sleep problems, which affect the quality of life of patients. Gender, disease activity and disease course are the influencing factors of mental disorders in IBD patients.
ABSTRACT
Objective:To investigate differences in stratum corneum components between sensitive skin and normal skin by attenuated total reflectance Fourier transform infrared (ATR-FTIR) spectroscopy, and to evaluate the value of ATR-FTIR spectroscopy in the study of pathogenesis of sensitive skin.Methods:From December 2018 to February 2019, 148 volunteers were recruited, who had lived in Shanghai for ≥ 6 years. Through questionnaire survey, lactic acid sting test and capsaicin test, the subjects were divided into normal skin group and sensitive skin group; meanwhile, total sting score and total burning score of the subjects were recorded in the lactic acid sting test and capsaicin test respectively. ATR-FTIR spectroscopy was performed to detect stratum corneum components, including natural moisturizing factor (NMF), stratum corneum lipids, free fatty acids (FFA) and β-sheet/α-helix (β/α) ratio; moreover, other non-invasive techniques were used to measure skin physiological parameters, including transepidermal water loss (TEWL), stratum corneum hydration (SCH) levels, stratum corneum lipids, skin pH, current perception thresholds of 3 peripheral sensory nerve fibers, and superficial skin blood flow perfusion. Spearman correlation coefficients between stratum corneum components and the total sting score as well as total burning pain score were analyzed, so were Pearson correlation coefficients between the stratum corneum components and skin physiological parameters.Results:A total of 73 volunteers completed all tests, including 15 males and 19 females aged 41.8 ± 8.9 years in the sensitive skin group, and 19 males and 20 females aged 42.8 ± 9.4 years in the normal skin group. Compared with the normal skin group, the sensitive skin group showed significantly decreased levels of stratum corneum NMF (30.90 ± 7.38 vs. 37.01 ± 8.77, t = 3.193, P < 0.01) and FFA (14.90 ± 6.75 vs. 20.45 ± 11.76, t = 2.422, P < 0.05), but significantly increased β/α ratio (3.17 ± 1.03 vs. 2.67 ± 0.56, t = -2.595, P < 0.05) ; there was no significant difference in stratum corneum lipid content between the two groups ( t = 1.458, P > 0.05). As far as the skin physiological parameters were concerned, the sensitive skin group showed significantly increased TEWL ( t = -3.496, P < 0.001), but significantly decreased current perception thresholds at a frequency of 5 Hz and epidermal density (both P < 0.05) compared with the normal skin group; no significant difference in stratum corneum lipid content was observed between the two groups ( P > 0.05). Correlation analysis revealed that NMF, FFA and β/α ratio were significantly correlated with TEWL ( r = -0.405, -0.562, 0.503, respectively, all P < 0.01) and total sting score ( rs = -0.401, -0.285, 0.316, respectively, P < 0.01 or 0.05) ; meanwhile, epidermal density was also significantly correlated with NMF ( r = 0.402, P < 0.01) and β/α ratio ( r = -0.369, P < 0.05). However, none of NMF, FFA and β/α ratio was correlated with stratum corneum lipid content, current perception thresholds of the 3 sensory nerve fibers, superficial skin blood flow perfusion or epidermal thickness (all P > 0.05) . Conclusions:NMF, FFA and β/α ratio in the stratum corneum significantly differed between the sensitive skin and normal skin, and were significantly correlated with some physiological parameters related to stratum corneum barrier function. ATR-FTIR spectroscopy is an effective method for evaluating barrier function of sensitive skin.
ABSTRACT
Objective To investigate reflectance confocal microscopy (RCM) features of irritant cutaneous reactions to sodium lauryl sulphate (SLS) in healthy persons aged from 18 to 60 years,to analyze effects of age and gender on cutaneous reactions,and to estimate the value of RCM in objective evaluation of cutaneous reactions.Methods An occlusive patch test was performed on the back of 120 healthy testees with 0.1％ and 0.5％ SLS solution (0.1％ and 0.5％ SLS groups) and distilled water (negative control group) for 48 hours.At different time points after the patch removal,clinical evaluation and RCM were performed.Results RCM imaging in the 0.1％ and 0.5％ SLS groups showed parakeratosis,indistinct structure of the stratum corneum,spongiosis and infiltration of inflammatory cells in the epidermis,and telangiectasia in the papillary dermis.The incidence of RCM features reached the peak until 24 hours after the removal of 0.1％ and 0.5％ SLS patches,and the incidence of telangiectasia in the dermis was up to 66.7％ and 95.0％ in the 0.1％ and 0.5％ SLS groups respectively.At 24 hours after the removal of 0.5％ SLS patch,the incidence of spongiosis was significantly lower in the males than in the females (68.9％ [42/61] vs.84.7％ [50/59],x2 =4.24,P ＜ 0.05).However,the incidence of spongiosis was significantly higher in testees aged 18-40 years than in those aged 41-60 years at 24 hours after the removal of 0.1％ SLS patch (53.3％[32/60] vs.35.0％[21/60],x2 =4.09,P ＜ 0.05).For the other RCM features,there were no significant differences in their incidence between different genders or age groups after the removal of 0.1％ and 0.5％ SLS patches (all P ＞ 0.05).Clinical evaluation showed that after the removal of 0.1％ and 0.5％ SLS patches,no significant difference in the incidence of irritant cutaneous reactions was observed between the males and the females or between the testees aged 18-40 years and those aged 41-60 years (all P ＞ 0.05).There were good correlations between the clinical evaluation results and RCM features.At 24 hours after the removal of 0.1％ SLS patch,the correlation coefficient between spongiosis and clinical evaluation results was up to 0.77,so was that between telangiectasia in the dermis and clinical evaluation results (both P ＜ 0.001).However,at 0.5 hour after the removal of SLS patches,clinical evaluation showed that the positive reaction rates were 2.5％ (3/120) and 12.5％ (15/120) in the 0.1％ and 0.5％ SLS groups respectively.In the meantime,there were 17.5 ％ (21 / 120) and 51.7％ (62/120) of testees manifesting more than 2 RCM features in the 0.1％ and 0.5％ SLS groups respectively,which were more similar to the clinical evaluation results at 24 hours after the removal of SLS patches (34.2％ [41/120] and 85.0％ [102/120] in the 0.1％ and 0.5％ SLS groups respectively) compared with the clinical evaluation results at 0.5 hour after the removal of SLS patches.Conclusions Neither gender nor age affects irritant cutaneous reactions to 0.1％ and 0.5％ SLS.Compared with clinical evaluation,RCM can evaluate cutaneous reactions more objectively and accurately in the early stage of irritant reactions.

ABSTRACT
Objective:To test the psychometric characteristics of the Chinese Version of the Illness Attitudes Scale(IAS-CV).Methods:Totally 297 patients (with somatoform disorders,major depressive disorder,generalized anxiety disorder,panic disorder,and obsessive-compulsive disorder diagnosed with ICD-10) and 212 normal people were assessed with IAS-CV,Beck Depression Inventory-Ⅱ and Beck Anxiety Inventory.Results:The confirmation factor analysis result of the nine-factor model of IAS-CV was x2/df=1.99,GFI =0.86,RMSEA =0.06.The total score of IAS-CV was correlated with BAI scores (r =0.45,P ＜0.01) and BDI-Ⅱ scores(r =0.42,P ＜0.01).Patients with somatoform disorders (62 ± 17) had higher scores than patients with other disorder,such as depression (43 ± 16),anxiety (46 ± 21),obsessive compulsive disorder (46 ± 15),and normal controls (35 ± 13).The Cronbach's α coefficients were 0.91 for IAS-CV and 0.62-0.91 for each subscale.The test-retest coefficients were 0.95 for the total scale and 0.67-0.93 for each subscale (P ＜ 0.01).Split-half coefficient was 0.94.The cut-off score of IAS-CV for screening somatoform disorders was 44.Conclusion:It suggests that the Chinese Version of the Illness Attitudes Scale(IAS-CV) has good psychometric features and could be used in clinical practice and research in China.
ABSTRACT
Objective To explore differences in phototest and photopatch test results, and in skin color?related parameters between healthy subjects and patients with chronic actinic dermatitis (CAD), and to examine their relationship with the melanocortin?1 receptor gene(MC1R)Arg163Gln variant. Methods Phototests were performed by using a sun simulator SUN1000, and skin color was analyzed by using Hexameter MX18 in 25 patients with CAD and 25 healthy subjects. The MC1R genotype at position?163 was determined by PCR. Photopatch tests were performed on 25 patients with CAD and 5 healthy subjects using a standard series of photoallergens(RuiMin)and an ultraviolet (UV)phototherapy equipment, SS?03A. Results Regarding phototest results, both UVA?minimal persistent pigment darkening dose(MPPD)and UVB?minimal erythema dose(MED)were significantly lower in CAD patients compared with healthy controls (both P 0.05), but that of the CAA genotype differed significantly between the two groups(P<0.01). UVA?MPPD and UVB?MED were both significantly lower in CAD patients with the CAA genotype at position?163 in the MC1R gene than in those without the genotype(P=0.055, 0.325, respectively). Conclusions Skin photobiological testing plays a critical role in the diagnosis of CAD. Further studies are needed to clarify the role of the CAA genotype at position?163 in the MC1R gene in the diagnosis, prevention and treatment of CAD.
ABSTRACT
BACKGROUND:A few studies have reported that autologous chondrocyte implantation is better than microfracture for treating cartilage defects of the knee. But there are few meta-analyses on the clinical outcomes of autologous chondrocyte implantation versus microfracture. OBJECTIVE:To evaluate the effects of autologous chondrocyte implantation versus microfracture in the treatment of cartilage defects of the knee based on existing clinical data. METHODS:A systematic search for control ed clinical trials or control ed prospective observational studies published from 1979 to January 2015 was done in electronic databases MEDLINE, EMBASE, CINAHL, the Cochrane Central Register, Wanfang, CNKI and VIP. The literatures about the effects of autologous chondrocyte implantation versus microfracture in the treatment of cartilage defects of the knee were retrieved. We screened the retrieved literature according to the inclusion and exclusion criteria and performed a Meta-analysis with the software RevMan 5.2 after identification of the relevant data. RESULTS AND CONCLUSION:Eight studies were enrol ed according to the selection criteria, which revealed a statistical y significant difference, representing a clinical y relevant superiority of autologous chondrocyte implantation over microfracture, in IKDC scores at final fol ow-up [weighted mean difference (WMD),-9.93;95%confidence interval (CI):-13.16 to-5.43;P<0.000 01] and available scores at 5-year fol ow-up [standard mean difference (SMD),-0.30;95%CI: -0.55 to-0.05;P=0.02). In contrast, there were no significant differences, thus representing no clinical relevant superiority of microfracture versus autologous chondrocyte implantation, in Tegner scores at final fol ow-up (WMD=0.44;95%CI:0.04 to 0.84;P=0.03), Lysholm scores at final fol ow-up (WMD=-10.21;95%CI:-33.68 to 13.26;P=0.39), and available scores at 2-year fol ow-up (SMD=-0.25;95%CI:-0.92 to 0.43;P=0.47). These findings demonstrate that autologous chondrocyte implantation can result in a better long-term outcome than microfracgure. However, whether autologous chondrocyte implantation has a better treatment effect than microfracture in general needs more research.
ABSTRACT
BACKGROUND:Previous studies have found that cyclic tensile stress can induce the proliferation of human periodontal ligament fibroblasts in a certain time. OBJECTIVE: To observe the effect of cyclic tensile stress on the expression of connective tissue growth factor in human periodontal ligament fibroblasts, and to clarify the role of JNK, p38MAPK, PI3K pathway in the cyclic tensile stress-induced expression of connective tissue growth factor in human periodontal ligament fibroblasts. METHODS:Human periodontal ligament fibroblasts culturedin vitro were given stimulation of cyclic tensile stress in vitro for 1, 6, 12, 24 hours using multi-channel cel stretch stress loading system (experimental group). Control group was set up and not given any stimulation at the same time. The cels under stress application for 12 hours were given specific inhibitors of JNK, p38MAPK, PI3K respectively at the beginning, and were compared with those with no inhibitors. The concentrations of connective tissue growth factor in the culture supernatant were measured by ELISA. The mRNA expression of connective tissue growth factor in human periodontal ligament fibroblasts was detected by real-time RT-PCR. RESULTS AND CONCLUSION:Compared with the control group, the expression of connective tissue growthfactor in human periodontal ligament fibroblasts under cyclic tensile stress began to increase at 1 hour, increased manifestly at 6 hours, reached the peak at 12 hours, and then decreased at 24 hours. The expression of connective tissue growth factor was reduced by the specific inhibitors of JNK, while the specific inhibitors of p38 MAPK, PI3K had not the same effect. In a certain time, the cyclic tensile stress can induce a time-dependent increase in mRNA and protein levels of connective tissue growth factor. Along with the extending of time, the expression of connective tissue growth factor begins to decrease. Cyclic tensile stress can regulate expression of connective tissue growth factor in human periodontal ligament fibroblasts via the JNK pathway.
ABSTRACT
BACKGROUND:It is unclearwhat kind of material for rotator cuff repair augmentation is the safest or most effective. OBJECTIVE:To review the basic research, clinical application and prospects of materials for rotator cuff repair augmentation. METHODS:Eligible studies were identified from electronic databases including EMbase, Medline, PubMed, OVID, Cochrane Library, Springerlink, CNKI, WanFang, and VIP. RESULTS AND CONCLUSION:There are four kinds of patches used for rotator cuff augmentation: tendon patches, non-degradable patches, extracelular matrix-based patches and degradable synthetic patches. Tendon patches have good mechanical strength, but postoperative foreign body reactions and increasing risk of infection and unable to recover the normal structure are problems to be solved. Non-degradable patches also have good mechanical strength, but the long-term safety is unclear. Extracelular matrix-based patches remain a lower mechanical strength and have a higher failure rate. Degradable synthetic patches are proposed to overcome these previous issues by combining wel-adjusted mechanical properties with biological additives and minimize risk of infection by completely absorbing in a time-dependent manner. However, migration of bioactive cels, regulation of degradation rate and suppression of acidic degradation products is are existing problems to be solved.

ABSTRACT
This study is to investigate the anticancer effects and mechanisms of Tegillarca granosa Linnaeus-1 [TG-1] on renal carcinoma OS-RC-2 cells in vitro. The proliferation of OS-RC-2 cells was evaluated under various concentrations of TG-1 using MTT assay. The apoptosis of OS-RC-2 cells was analyzed using acridine orange/ethidium bromide staining. And the cell cycle distribution of OS-RC-2 cells was detected by flow cytometry. In addition, the expression level of Ki67 mRNA was examined by RT-PCR and level of casepase-3 was examined by Western blot analysis. TG-1 incubation significantly inhibited the proliferation of renal carcinoma OS-RC-2 cells and arrested cells at G[0]/G[1] phase [P <0.05]. And TG-1 also significantly inhibited the expression of Ki67 mRNA [P<0.05]. Additionally, TG- 1 significantly promoted apoptosis and the expression of caspase-3 in cells [P<0.05]. Moreover, the optimal effects of TG-1 was achieved at the concentration of 100 mg/L The results indicate that TG-1 has antitumor effects on renal carcinoma OS-RC-2 cells and that the underlying mechanisms may be acted through inhibiting proliferation and Ki67 mRNA expression, and promoting apoptosis and caspase-3 expression.

BACKGROUND:A large number of studies have reported that endoscopic radiofrequency ablation surgeries were better than traditional open surgeries for gluteal muscle contracture, but there is no meta-analysis on the clinical outcomes of endoscopic surgeries versus traditional open surgeries. OBJECTIVE:To evaluate the effects of endoscopic radiofrequency ablation surgeries versus traditional open surgeries in the treatment of gluteal muscle contracture. METHODS:Eligible studies were identified from electronic databases including EMbase, Medline, PubMed, OVID, Cochrane Library, Springerlink, CNKI, WanFang, and VIP between January 1970 and May 2014. The literatures about the clinical efficacy of endoscopic radiofrequency ablation surgeries versus traditional open surgeries in the treatment of gluteal muscle contracture were retrieved. We screened the retrieved literature according to the inclusion and exclusion criteria and performed a Meta analysis with the software RevMan 5.2 after identification of the relevant data. RESULTS AND CONCLUSION:A total of 830 patients from 14 studies were included for the analysis, including 394 patients who underwent endoscopic surgeries and 436 patients who underwent traditional open surgeries. Among the main outcomes measured, the incidence of postoperative pain (relative risk=0.33, 95%confidence interval (CI):0.27-0.42, P0.05) between the two groups. Endoscopic radiofrequency ablation surgeries are similar to traditional open surgeries in the curative effects, recurrence rate and surgery duration, and are better than traditional open surgeries in the incisional length, postoperative pain, postoperative off-bed activity time, postoperative hospitalization and postoperative complication.

ABSTRACT
Objective To analyze epidemiologie and injury characteristics of traffic injuries in Shenzhen through emergency department. Methods A questionnaire was pre-designed to collect data of patients admitted to six general emergency departments of six district in Shenzhen from January 2007 to December 2007 for clinical analysis. Results There were 1 328 patients with road traffic injuries, at age range of 2-84 years (average 31 years). According to occupation, most patients were local workers and migrant workers (57.8%). The accidental vehicles were mostly cars (48.5%). Most accidents (78.6%) occurred in urban streets. As for time distribution of traffic injuries, most injuries happened on Friday and Saturday (accounting for 17.8% and 18.7% respectively), especially on Friday (r = 0.166 0, P <0.01). There was central tendency around 15:35 p.m. in one day (r = 0.285 6, P < 0.01). The age of male was (32.36±8.70) years and that of female (29.96±4.32) years, with statis-tical differences (P < 0.05). Of patients followed up, 84.4% patients could work on their original jobs, 8.5% needed ehange of their jobs and 7.1% lost the ability of work. Conclusions It is neeessary to strengthen road safety education among local workers and migrant workers to improve their awareness of road safety. Traffic administrators and road safety marks should be added in the chief period and districts where road traffic injuries happen most frequently. Controlling the number of small cars may be effective to reduce traffic accidents.
ABSTRACT
Objective: To translate Millon Clinical Multiaxial Inventory Ⅲ (MCMI-Ⅲ) into Chinese, and then test its reliability and validity.
