Objective To evaluate the effect of photo-activated disinfection(PAD)as a kind of adjuvant treatment on moderate to severe chronic periodontitis.Methods 21 patients with the chronic periodontitis(totally 218 selected sites)were randomly enrolled and divided into group A(minocycline hydrochloride),group B(PAD),group C(PAD + minocycline hydrochloride),and group D(no adjunctive therapy)for the adjunctive treatment after receiving the scaling and root planing(SRP).Periodontal indexs as probing depth(PD),bleeding on probing(BOP)and clinical attachment loss(CAL)were examined at the baseline,6 and 12 weeks after the treatment.Meanwhile,periodontal pathogens as Porphyromonas gingivalis(Pg)and Tannerella forsythia(Tf)from subgingival plaque of group A,B and C were detected by Real-time PCR.Results Compared with the baseline,the periodontal inflammations of all groups were improved signiffcantly at 6 and 12 weeks after the treatment(P<0.001),and group A,group B and group C were better than group D(P<0.001),group C was better than group A(P<0.001);Furthermore,the concentration of Pg and Tf was decreased significantly(P<0.001),and there was no difference among the three groups with adjunctive therapy.Conclussion As the adjunctive treatment of SRP,PAD could achieve the same and even better effect than minocycline hydrochloride ointment.

Objective:To assess the real-world patient satisfaction with the outcomes in Chinese patients who received HYC-24/HYC-24+ for the treatment of moderate to severe nasolabial folds (NLF).Methods:This study was a prospective, observational, multicenter, real-world cohort study in which patients accepted treatment with HYC-24/HYC-24+ in China during a period from August 2018 to August 2020 at Beijing Lidu Medical Beauty Hospital, Hangzhou Yanshu Yuerong Medical Aesthetic Clinic, and Guangzhou Yuexiu Plastic Surgery Hospital and were followed up for up to 1 year. Patients were adults aged 18 to 65 years with moderate to severe NLF who had not received cosmetic treatment for NLF within 6 months prior to study enrollment. Post-treatment study visits were conducted at Months 1, 6, 9, and 12, but only Months 6 and 9 were required visits. The primary patient-reported outcomes endpoints included the FACE-Q satisfaction with outcome total score (a score from 0 to 100: a higher score indicates better outcomes and higher patient satisfaction), FACE-Q appraisal of lines - NLFs total questionnaire score mean change from baseline (a score from 0 to 100: a higher score indicates the patient was less troubled by NLF in the past week), and proportion of patients who reported that they looked younger than the actual age on the FACE-Q patient perceived age visual analog scale (VAS). Investigator-assessed endpoints included the proportion of patients with a global aesthetic improvement scale (GAIS) score of ≥ 1 point and the proportion of patients with an improvement in NLF severity of ≥ 1 point using the nasolabial fold severity scale (NLFSS). Statistical analyses were performed with SAS software, version 9.4. Measurement data were expressed as Mean±SD, and count data were expressed using cases(%). For both measurement and count data, P values were calculated on the difference between score values at different time points versus baseline using the Wilcoxon signed rank test. Results:A total of 52 subjects were enrolled and treated. Among these subjects, 7 were not included in the 6-month effectiveness analysis data set because the visit time exceeded the visit assessment window, and only 9 patients completed the 12-month visit. All patients were Chinese women, aged 26 to 62 years old, with a mean age of 40.7 years. The FACE-Q satisfaction with outcome total score was (68.76 ± 21.03) points (38-100) at Month 6, and (65.44±18.24) points (24-100) at Month 9, indicating high patient satisfaction with the treatment. The FACE-Q appraisal of lines-NLFs total score was (42.4±15.1) points (10-69) at baseline, (76.9±20.6) points (36-100) at Month 6, and (74.2±16.7) points (36-100) at Month 9, both significantly higher than the baseline scores (both P<0.01). The mean change from baseline in the FACE-Q appraisal of lines-NLFs total scores at Month 6 and Month 9 were 34.9 and 31.8 points, respectively, indicating the disturbance caused by NLF was relatively mild after treatment. The proportion of patients who believed they looked younger than their actual age on the FACE-Q patient perceived age VAS increased from 28.9% (15/52) at baseline to 77.8% (35/45) at Month 6, and 73.1% (38/52 ) at Month 9. The differences were all statistically significant compared to baseline ( P <0.01). At each post-baseline visit, all patients had ≥ 1-point improvement on the GAIS scale, indicating an improvement in patient NLF appearance in the investigators’ opinion. In terms of the NLFSS assessment, 97.8% (44/45) and 82.7% (43/52) of patients achieved a ≥ 1-point improvement on the NLFSS at Months 6 and 9, respectively. No adverse events were reported during the study. Conclusion:In a real-world setting, after the administration of HYC-24/HYC-24+ to Chinese patients, the patients were satisfied with the outcomes based on validated questionnaires. The patients also reported looking younger than their actual age and being less disturbed by NLF. Clinician-reported outcomes were consistent with patient-reported outcomes, indicating improvement in NLF.

Dermatomyositis is an autoimmune disease mainly involving the skin and muscles, as well as the heart, lungs, and joints, and it may also be complicated by malignant tumors. Among these complications, interstitial lung disease (ILD) is of particular concern. Because of the urgent onset and rapid progress, ILD is hard to diagnose at the early stage, usually leading to treatment delay. Furthermore, ILD is the common cause of death in patients with dermatomyositis. This review summarizes types of skin lesions of, serum biomarkers for and radiological features of dermatomyositis to help evaluate the risk, severity and prognosis of it complicated by ILD.

Objective:To explore the features of free uroflow(FF) curve patterns in female patients with detrusor underactivity(DU) and their clinical significance.Methods:Data of 275 adult female patients with lower urinary tract symptoms(LUTS) underwent urodynamic studies(UDS) at urology center of our hospital from June 2014 to June 2016 were analyzed retrospectively. The uroflow curve patterns of patients with DU were classified and analyzed in the context of parameters of FF, cystometry (CM), and pressure-flow study(PFS). The prevalence of each abnormal uroflow curve pattern in DU patients were calculated and compared with those in non-DU patients.Results:No bell-shaped curve was found in 141 patients with DU. The abnormal curve patterns can be divided into 5 types: Type Ⅰ (bell-shaped curve with saw tooth) in 20 cases (14.2%), Type Ⅱ (box-like curve) in 34 cases (24.1%), Type Ⅲ (triangle curve with decreasing slop) in 62 cases(43.9%), Type Ⅳ (triangle curve with increasing slop) in 4 cases (4.3%), Type Ⅴ (tide-wave curve)in 19 cases (13.5%). Maximum flow rate of free uroflow(Q max.FF) of type Ⅰ [(28.4±9.7) ml/s] was significantly greater than that of type Ⅱ, Ⅲ and Ⅴ[(17.0±4.1), (15.8±5.4) and (12.9±6.4) ml/s, P<0.05]. Flow time of free uroflow(FT.FF) of type Ⅲ and Ⅴ [(43.7±17.2) and (50.1±28.9)s] were significantly longer than that of type Ⅰ and Ⅱ [(18.5±7.3)s and (27.2±9.7)s, P<0.05]. Post voided residual > 50ml was noted in 19 cases (30.6%) of type Ⅲ, 7 cases (36.8%) of type Ⅴ, 1 case (2.9%) of type Ⅱ and no one in type Ⅰ and Ⅳ. Abnormal manifestations in cystometry mainly included bladder hypersensitivity, detrusor overactivity, and stress urinary incontinence. Detrusor pressure at Q max (Pdet.Q max) of type Ⅴ [(7.4±5.0) cmH 2O] was significantly lower than that of type Ⅰ, Ⅱ, Ⅲ [(11.8±6.7), (12.0±5.3), (12.1±5.0) cmH 2O, P<0.05]. Among 134 cases of non-DU, there were type Ⅰ curves in 88 cases (65.7%), type Ⅱ curves in 4 cases (2.9%), type Ⅲ curves in 15 cases (11.2%), type Ⅳ curves in 1 cases (0.7%), type Ⅴ curves in 7 cases (5.2%). And normal bell-shaped curves in 19 cases(14.2%). The prevalence of type Ⅱ, Ⅲ and Ⅴ in DU patients was significantly higher than that in the non DU patients ( P<0.05). Conclusions:This study reveals that the characteristics of reduced detrusor contractility and duration, prolonged bladder emptying or incomplete emptying can be reflected in the patterns of free uroflow curve in female patients with DU. The abnormalities of these free uroflow curve patterns, especially type Ⅱ, Ⅲ and Ⅴ will be helpful in preliminarily screening DU in females.

Objective:To investigate the effect of CHI3L1 on the biological function of chondrocytes and its role in lumbar facet joint degeneration.Methods:The human lumbar facet joint articular cartilage were collected, and the relative mRNA expression of CHI3L1 gene detected by quantitative fluorescence PCR. Then explored the correlation between joint degeneration and gender, age and relative mRNA expression of CHI3L1. Human chondrocytes were cultured in vitro. The effects of CHI3L1 on chondrocyte proliferation, cycling, and apoptosis, as well as expression of related inflammatory factors, were investigated. The mechanism by which CHI3L1 regulates the degeneration of articular cartilage was investigated using the signal transduction pathway protein chip.Results:There was a positive correlation between the grade of degeneration in lumbar facet joint and the relative expression of CHI3L1 gene mRNA ( r=0.76, P<0.001). There was no correlation with the patient's gender ( r=-0.12, P=0.500). A positive correlation between the age of patients and the relative expression of CHI3L1 gene mRNA was found ( r=0.47, P=0.005). Compared with the non-degenerative group, the expression of CHI3L1 gene mRNA significantly increased in the degenerative group, and the expression of CHI3L1 gradually increased with the aggravation in the grade of degeneration ( F=18.90, P<0.001). Compared with the non-degenerative group, the chondrocytes in the CHI3L1 group had significantly lower proliferation at 48 h (OD 490/fold=7.132), 72 h (OD 490/fold=4.803), 96 h (OD 490/fold=2.431) and 120 h (OD 490/fold=0.009). The ratio of chondrocytes in G1 phase, S phase and G2/M phase were 85.03%±3.05%, 12.78%±2.29% and 0.90%±0.76% in the CHI3L1 group, and 73.93%±2.73%, 22.81%±1.93% and 0.99%±0.87% in control group, respectively. There were significant differences in the percentage of chondrocytes in G1 phase ( t=4.70, P<0.001) and S phase ( t=5.80, P<0.001) between the two groups. The percentages of apoptosis in chondrocyte in CHI3L1 group and control group were 8.64%±0.76% and 5.68%±1.13%, which has a statistically difference ( t=4.47, P<0.001). The expression of IL-6 in chondrocytes of CHI3L1 group was 49.60±0.01 pg/ml, which was higher than that of 47.88±0.01 pg/ml in the control group ( t=132.70, P<0.001). The expression of TNF-α was 95.93±0.02 pg/ml, which was higher than 90.69±0.02 pg/ml in the control group ( t=376.10, P<0.001). There was significant difference in expression of IL-6 in chondrocytes between the CHI3L1 group and the control group ( t=132.72, P<0.001). The expression of TNF-α ( t=376.10, P<0.001) was statistically difference. Protein chip detected 53 proteins with significant differences in expression and 43 proteins with significant differences in protein phosphorylation levels. Bioinformatics analysis was used to identify 16 signaling pathways in which the above different proteins might be involved, including ErbB, PI3K, Akt, Ras, JAK, STAT3, MAPK pathway. In the MAPK pathway, the expression of MAPK1 and RAF1 proteins was higher in the chondrocytes of the CHI3L1 group than in the control group (1.094±0.00 vs. 0.814±0.00, 0.988±0.00 vs. 0.786±0.00; t=103.16, P<0.001; t=54.32, P<0.001). Compared with the control group, the expression of MAPK1 and RAF1 proteins was significantly increased in the chondrocytes of the CHI3L1 group. Conclusion:The expression of CHI3L1 is corrected to articular cartilage degeneration. CHI3L1 is able to inhibit the proliferation of articular chondrocytes, which regulated the cycling of chondrocytes from G1 phase to S phase, promote the apoptosis of chondrocytes, and promote the expression of IL-6 and TNF-α in chondrocytes. Regulation of chondrocytes biological function through the MAPK pathway, which is a potential biomarker for the clinical diagnosis and treatment of lumbar joint degeneration.

Objective:To investigate the effects of cyclic tensile stress on the function and degeneration of nucleus pulposus cells.Methods:The human primary nucleus pulposus cells were isolated and cultured. The cyclic tensile stress (100 000 μ?, 10% tensile strain, 0.1 Hz, 8 640 cycles) was loaded on the cells for 24 h. The proliferation of the cells was examined by MTT method. The cell cycle and apoptosis were detected through flow cytometry. Gene expression profile chip was used to detect the differentially expressed genes between the tensile stress group and control group. The function of these gene was analyzed by bioinformatics. The expression of inflammatory related factors, TGF-β, matrix degrading enzymes and extracellular matrix molecules were examined by qRT-PCR.Results:The cyclic tensile stress significantly promoted proliferation and cell cycle of nucleus pulposus cells. The cell percentage of S phase ( t=5.336, P<0.05) and G2/M phase ( t=7.288, P<0.01) was significantly different between the tensile stress group and control group. The cyclic tensile stress inhibited apoptosis of nucleus pulposus cells (8.56%±0.48% vs 10.63%±0.32%, t=4.474, P<0.05). A total of 866 differentially expressed genes were detected. Gene ontology analysis showed the roles of these genes in cells including focal adhesion, extractable matrix, membrane raft, condensed chrome kinetochore, cytoskeleton, etc. The cyclic tensile stress significantly affected the mRNA expression of inflammatory related factors, TGF-β genes, matrix proteinase and extracellular matrix molecules. Compared with the control group, the mRNA expression of inflammatory related factors IL15 ( t=5.379, P<0.05), IGF1 ( t=5.454, P<0.05) and IGFBP7 ( t=13.57, P<0.01) were significantly decreased in the tensile stress group; The mRNA expression of TGF-β genes TGFB1 ( t=6.931, P<0.05), TGFB2 ( t= 15.56, P<0.01) and TGFB3 ( t=7.744, P<0.05) were significantly increased in the tensile stress group; The mRNA expression of matrix proteinase ADAMTS3 ( t=5.241, P<0.05) and MMP19 ( t=24.72, P<0.01) were significantly decreased, and TIMP3 ( t=8.472, P<0.01) increased in the tensile stress group; The mRNA expression of extracellular matrix molecules COL2A1 ( t=5.871, P<0.05), FLRT2 ( t=5.216, P<0.05) and FN1 ( t=4.289, P<0.05) were significantly increased. Conclusion:The cyclic tensile stress promoted cell cycle and proliferation and inhibited apoptosis of nucleus pulposus cells. The cyclic tensile stress may affect the function and degeneration of nucleus pulposus cells by regulating the expression of inflammatory related factors, TGF-β, matrix degradation enzymes and ECM molecules.

The clinical data of 380 patients undergoing loop electrosurgical excision procedure(LEEP) conization for cervical intraepithelial neoplasia grade 3(CIN3) at the Affiliated Hospital of Xuzhou Medical University from January 2017 to December 2019 were retrospectively analyzed. Univariate and multivariate logistic regression analyses were used to determine the risk factors of positive margin and residual lesions following conization. One hundred and twelve cases (29.5%) had positive margins, and the risk factors for positive margins were positive high-risk human papillomavirus ( OR=4.92, 95% CI: 1.81-13.36), high-grade lesions on thin cytologic test (TCT)screening ( OR=3.95, 95% CI: 2.42-6.42), and glandular involvement ( OR=3.58, 95% CI: 1.93-6.63). The hysteretomy was performed following conization in 169 hundred and sixty-nine patients who had difficulty in follow-up or no fertility intension, among whom 51 (30.2%) had residual lesions; logistic regression analysis showed that positive margins on LEEP were a risk factor for residual lesions at the time of hysterectomy ( OR: 2.83, 95% CI: 1.44-5.59). The study indicates that positive HR-HPV, high-grade TCT lesions, and lesions involving glands are risk factors for positive margins in CIN3 patients undergoing LEEP conization; and positive margins is risk factor for residual lesions following conization,to which more attention should be paid in clinical practice.
