Objective:To compare the in vitro susceptibility of fluconazole-resistant Candida albicans strains from superficial and deep infections to 8 antifungal drugs, and to compare drug resistance mutations in these strains. Methods:According to the Clinical and Laboratory Standards Institute (CLSI) protocol M27-A4, 26 deep infection-derived and 33 superficial infection-derived drug-resistant Candida albicans strains were tested for in vitro susceptibility to 8 antifungal drugs (fluconazole, voriconazole, itraconazole, posaconazole, amphotericin B, fluorocytosine, terbinafine, and micafungin) alone or in combination. DNA was extracted from all drug-resistant strains, and mutations in 3 drug resistance genes, including ERG3, ERG11 and FUR1, were detected by PCR. Normally distributed measurement data with homogeneous variance were compared between two groups by using two-independent-sample t test, non-normally distributed measurement data with non-homogeneous variance were compared using Mann-Whitney U test, and enumeration data were compared using chi-square test. Results:The minimum inhibitory concentrations (MICs) of fluconazole, itraconazole, voriconazole, posaconazole and fluorocytosine all significantly differed between the superficial infection group and deep infection group (all P < 0.05) , while there was no significant difference in the MIC of amphotericin B or micafungin between the two groups (both P > 0.05) . The MIC of terbinafine was >64 μg/ml in 96.6% of the above strains, so could not be compared between groups. As combination drug susceptibility testing revealed, the combination of terbinafine with azoles (fluconazole, voriconazole, itraconazole or posaconazole) showed synergistic inhibitory effects against 15 Candida albicans strains (7 strains from deep infections, 8 strains from superficial infections) , with fractional inhibitory concentration (FIC) indices being 0.033 to 0.187; no marked synergistic effect was observed in the combinations between fluorocytosine and azoles, between fluorocytosine and amphotericin B, or between amphotericin B and fluconazole, with the FIC indices being 0.56 to 1.125. The missense mutation V351A in the ERG3 gene was identified in all the 33 (100%) superficial infection-derived strains, as well as in 13 (50%) deep infection-derived strains, and the mutation A353T in the ERG3 gene was identified in 4 (15%) deep infection-derived strains; as for the ERG11 gene, missense mutations identified in the superficial infection-derived strains included I437V (32 strains, 97%) , Y132H (23 strains, 70%) , T123I (16 strains, 48%) , K128T (6 strains, 18%) , D116E (5 strains, 15%) , A114S (4 strains, 12%) , E266D (2 strains, 6%) , G448E (2 strains, 6%) , and G465S (2 strains, 6%) , while missense mutations identified in the deep infection-derived strains included I437V (23 strains, 88%) , E266D (13 strains, 50%) , E260G (5 strains, 19%) , and V488I (4 strains, 15%) ; the missense mutation R101C in the FUR1 gene was identified in 11 (33%) superficial infection-derived strains, but not identified in deep infection-derived strains. Conclusion:The drug susceptibility and drug resistance mutations differed to some extent between superficial infection- and deep infection-derived fluconazole-resistant Candida albicans strains.

Objective To analyze the characteristics of pattern elements and the distribution of patterns of femoral head necrosis, hip osteoarthritis, and hip rheumatoid arthritis, in order to provide a theoretical basis for the "different diseases with the same pattern" of chronic bone diseases. Methods A cross-sectional survey was conducted to select patients with femoral head necrosis Association Research Circulation Osseous Ⅰ-Ⅱ stages, hip osteoarthritis Kellgren & Lawrence Ⅰ-Ⅱ stages, and acute or subacute hip rheumatoid arthritis who visited the Minimally Invasive Arthrology Department, Traumatology Department, and Rheumatology and Immunology Department of Beijing University of Chinese Medicine Third Affiliated Hospital from June 2020 to June 2022. The " case report form - traditional Chinese medicine pattern manifestation scale" previously developed by our team was used to collect the pattern manifestations, which were included into an Excel 2020 spreadsheet to establish a database. SPSS 20.0 software was used for factor analysis and cluster analysis to extract pattern element information, such as disease nature and location, in order to summarize the characteristics of pattern elements, the distribution of patterns, and the similarities and differences of the three kinds of early hip joint diseases.Results A total of 410 patients were included, including 150 patients with femoral head necrosis, 160 patients with hip osteoarthritis, and 100 patients with hip rheumatoid arthritis. The pattern elements of the disease nature of femoral head necrosis include phlegm (dampness), blood stasis, yang deficiency, essence deficiency, and qi deficiency. The pattern types were initially divided into four categories: syndrome of meridian obstruction (43.33%), syndrome of phlegm and blood stasis blocking collaterals (38.00%), syndrome of liver and kidney deficiency (12.00%), and syndrome of kidney essence deficiency (6.67%). The pattern elements of the disease nature of hip osteoarthritis include phlegm (dampness), blood stasis, qi deficiency, essence deficiency, yang deficiency, and cold (dampness). The pattern types were preliminarily divided into five categories: syndrome of spleen and kidney deficiency (37.50%), syndrome of meridian obstruction (26.87%), syndrome of cold and dampness obstruction (18.75%), syndrome of phlegm and blood stasis obstruction (9.38%), and syndrome of liver and kidney deficiency (7.50%). The pattern elements of the disease nature of hip rheumatoid arthritis include phlegm (dampness), blood stasis, qi deficiency, yin and yang deficiency, cold (dampness), and essence deficiency. The pattern types were preliminarily divided into four categories: syndrome of phlegm and blood stasis obstruction (34.00%), syndrome of cold and dampness obstruction (28.00%), syndrome of blood stasis blocking collaterals (23.00%), and syndrome of liver and kidney deficiency (15.00%). Overall, the top five pattern manifestations of the three kinds of hip joint diseases were hip joint pain (96.59%), tenderness (93.90%), fixed pain (87.56%), heavy joints (85.37%), and sourness of lower limbs (75.37%). The pattern elements of the disease nature include phlegm (dampness), blood stasis, qi deficiency, etc. The pattern types were preliminarily divided into five categories: syndrome of phlegm stasis blocking collaterals (33.17%), syndrome of meridian obstruction (31.95%), syndrome of cold dampness obstruction (21.46%), syndrome of liver and kidney deficiency (7.32%), and syndrome of spleen and kidney deficiency (6.10%). There were 21 similar pattern manifestations in the three kinds of early hip joint diseases, with blood stasis and spleen deficiency being the main pattern.Conclusion The common pattern characteristics of three kinds of early hip joint diseases are spleen deficiency and blood stasis. In addition, femoral head necrosis is accompanied with phlegm-dampness pattern, hip osteoarthritis is accompanied with kidney deficiency and phlegm-dampness pattern, hip rheumatoid arthritis is accompanied with kidney deficiency and cold-dampness pattern.

Idiopathic thrombocytopenic purpura (ITP) is a common bloody disease with a high incidence in children, but its diagnostic method is exclusive diagnosis, and the existing detection techniques are mostly invasive, which may cause secondary injury to patients and also may increase the risk of disease. In order to make up for the lack of the detection method, this study made a preliminary exploration on the diagnosis of children's ITP from the perspective of infrared thermography. In this study, a total of 11 healthy children and 22 ITP children's frontal infrared thermal images were collected, and the pattern characteristic (PFD), average temperature (Troi) and maximum temperature (MAX) characteristics of 7 target areas were extracted. The weighted PFD parameters were correlated with the platelet count commonly used in clinical diagnosis, and the sensitivity and specificity of the weighted PFD parameters for children's ITP were calculated through the receiver operating characteristic curve (ROC). The final results showed that the difference of the weighted PFD parameters between healthy children and ITP children was statistically significant, and the parameters negatively correlated with platelet count. Under the ROC curve, the area under the curve (AUC) of this parameter is as high as 92.1%. Based on the research results of this paper, infrared thermography can clearly show the difference between ITP children and healthy children. It is hoped that the methods proposed in this paper can non-invasively and objectively describe the characteristics of ITP infrared thermal imaging of children, and provide a new ideas for ITP diagnosis.

ObjectiveTo observe the clinical characteristics and influencing factors of adverse events of Osteoking and provide a basis for its rational use in clinical practice. MethodA prospective and multicenter Cohort study with large samples was conducted to observe the effects of Osteoking in the treatment of 922 patients with knee osteoarthritis from 20 hospitals from May 1, 2020 to December 31, 2021. Patients who were treated with Osteoking were set as the exposed cohort, and those who were not treated with Osteoking were set as the non-exposed cohort. The gender, age, body mass index (BMI), occupation, allergy history, past medical history, hospital information, medication, and the occurrence of adverse events of the patients were recorded, and the incidence of adverse events was analyzed, as well as its characteristics and factors. ResultA total of 922 patients with knee osteoarthritis were involved, including 274 males (29.72%) and 648 females (70.28%), from which 617 cases were in the exposed cohort, and 305 cases were in the non-exposed cohort. A total of 25 adverse events occurred in both cases, accounting for 2.71% of the total number of cases, with 17 cases in the exposed cohort (2.76%) and eight cases in the non-exposed cohort (2.62%). There was no difference in the incidence rate between the two groups (P=0.907). The age group with the highest incidence of adverse events was between 50 and 59 years old in the exposed cohort (4.61%). The incidence rate in women was 3.49%, slightly higher than 1.07% in men, but there was no difference (P=0.156). According to the systematic classification of adverse events, five cases were respiratory, thoracic, and mediastinal diseases, with an incidence rate of 0.81%. There were two cases of infection and infection diseases, two cases of skin and subcutaneous tissue diseases, two cases of heart-related diseases, two cases of symptoms and signs (not otherwise classified), and two cases of eye organ diseases, and the incidence rate was 0.32%. There was one case of systemic disease, one case of neuropathy, one case of heart organ disease, and one case of vascular hypotension disease, and the incidence rate was 0.16%. During the trial, a total of seven adverse reactions occurred. Among them, there were two cases of dry pharynx, two cases of dizziness, one case of drowsiness, one case of hypotension, and one case of eye discharge, with an incidence rate of 1.13%. Through binary Logistic regression analysis, it was found that among the factors that may affect the occurrence of adverse events in the exposed group, traditional Chinese medicine hospitals were the protective factors for the occurrence of adverse events (OR=0.200, P=0.002), while gender, age, BMI, occupation, allergy history, past medical history, and hospital level cannot be considered to have an impact on the occurrence of adverse events. ConclusionOsteoking can be used to treat knee osteoarthritis of patients of all ages and genders by doctors from hospitals of different levels with higher safety, with occasional and mild adverse events, and seeing a doctor in a traditional Chinese medicine hospital can reduce the occurrence of adverse reactions.

ObjectiveTo explore the clinical efficacy of Osteoking combined with non-steroidal anti-inflammatory drugs in the treatment of knee osteoarthritis based on real-world data and provide a basis for clinical medication. MethodFrom May 2020 to December 2021, the data of a total of 1 002 patients with knee osteoarthritis who did not undergo knee joint replacement surgery was collected through the registration method. 952 patients were ultimately included, including 133 cases orally taking Osteoking combined with non-steroidal anti-inflammatory drugs as the observation group and 73 cases orally taking non-steroidal anti-inflammatory drugs alone as the control group. Statistical analysis was conducted on the baseline data, VAS scores, WOMAC scores, and other items. The visit point is the 4th and 8th weeks after registration. In order to further elucidate the clinical efficacy of Osteoking combined with non-steroidal anti-inflammatory drugs in the treatment of knee osteoarthritis, the effective components of Osteoking and the relevant gene sets of non-steroidal anti-inflammatory drugs and knee osteoarthritis were obtained through network pharmacology methods and retrieval in bone injury cross database, TCMSP, and other databases. Venn analysis was performed on the relevant gene sets, and a PPI network diagram was constructed. Then key core targets were screened out, and enrichment GO and KEGG enrichment analyses were conducted. ResultThe VAS score of the observation group decreases by an average of (-2.79±1.206) scores in the 4th week, which is better than the control group [(-2.73±1.575) scores, P<0.05]. The VAS score of the observation group decreases by an average of (-3.97±1.308) scores in the 8th week, which is better than the control group [(-3.89±1.822) scores, P<0.05]. The total WOMAC score of the observation group decreases by an average of (-52.07±21.677) scores points in the 8th week, which is significantly better than the control group [(-46.75±25.368) scores, P<0.05]. The observation group has an average decrease of (-10.99±4.229) scores in WOMAC (pain) score in the 8th week, which is better than the control group [(-10.03±5.535) scores, P<0.05]. The observation group has an average decrease of (-1.49±2.901) in WOMAC (stiffness) score in the 4th week, which is better than the control group [(-0.92±1.998) scores, P<0.05], and the observation group has an average decrease of (-1.90±3.200) scores in WOMAC (stiffness) score in the 8th week, which is better than the control group [(-1.26±2.230) scores, P<0.05]. The observation group shows an average decrease of (-39.17±16.562) scores in WOMAC (joint function) score in the 8th week, which is significantly better than the control group [(-35.47±20.098) scores, P<0.05]. According to network pharmacology analysis, the core network target of Osteoking in treating knee osteoarthritis is manifested as regulating signal pathways such as signal transduction transcription activator 3(STAT3), vascular endothelial growth factor A(VEGFA), tumor necrosis factor (TNF) to regulate cell signaling, angiogenesis, chondrocyte proliferation and migration, and inflammatory cells, thereby inhibiting inflammatory reactions, reducing damage, and delaying the development of the disease. ConclusionAfter a 4-week and 8-week course of treatment for knee osteoarthritis with Osteoking combined with non-steroidal anti-inflammatory drugs, there is a significant therapeutic effect on relieving pain and joint stiffness and improving joint function. In network pharmacology, Osteoking is involved in regulating inflammatory factors, metabolic response-related biological processes, the proliferation and apoptosis of chondrocytes, etc. in the treatment of knee osteoarthritis, resulting in anti-inflammatory and analgesic effects and improving joint mobility and joint stiffness. Therefore, it is worthy of clinical promotion and application.

ObjectiveTo investigate the differences in clinical efficacy of different medication regimens of Wangbi Tablets (尪痹片) for knee osteoarthritis (KOA) in a real-world setting, providing a basis for rational clinical use of Wangbi Tablets. MethodsA prospective registry study was conducted, involving 2,999 KOA patients registered in 30 hospitals nationwide from January 26th, 2019, to December 17th, 2021. Based on the use of Wangbi Tablets during the observation period, patients were divided into a monotherapy group (1,507 cases) and a combination therapy group (1,492 cases), and the combination group can be further divided into Wangbi Tablets plus Chinese medicine (CM), Wangbi Tablets plus western medicine (WM), and Wangbi Tablets plus Chinese and western medicine (CM+WM) subgroups. The baseline data of patients in the monotherapy group and the combination group were compared, including age, gender, body weight, medication time, clinical stage, K-L grade, and others. Efficacy indicators included the Visual Analog Scale (VAS) score, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score, and EuroQol five-dimensional (EQ-5D) health index, which were evaluated before and after 4-, 8- and 12-week treatment, and the difference before and after treatment was calculated after 4, 8 and 12 weeks of treatment. The difference between the baseline and 12 weeks of treatment of all the above indicators was used as the dependent variables, and gender, age, body mass index (BMI), course of disease, K-L grade, and clinical stage were used as independent variables, when multiple linear regression was taken to explore the influencing factors of the efficacy. At the same time, the occurrence of major symptoms (including morning stiffness, joint swelling, soreness of waist and knees, fear of wind, and fear of cold) was counted, and the disappearance of symptoms at each time point was counted after 4, 8, and 12 weeks of treatment. ResultsAt baseline, there were no statistically significant differences in gender and age distribution between the monotherapy and combination therapy groups (P>0.05); the proportion of patients in the acute stage and recovery stage was higher in the monotherapy group than in the combination therapy group, while the proportion in the remission stage was lower (P<0.05); the VAS score was higher in the monotherapy group, and the EQ-5D index was lower (P<0.01), with no statistically significant difference in total WOMAC score between the two groups (P>0.05). Compared to those measured before treatment and at previous timepoint, the VAS score and WOMAC total score significantly decreased in both groups, while EQ-5D value increased (P<0.05). The difference in VAS score between baseline and after 12-week treatment was higher in the monotherapy group than the combination group, while the differences in WOMAC total score and EQ-5D value between baseline and after 4-, 8- and 12-week treatment were higher in the combination group (P<0.05). Multiple linear regression showed that VAS score before treatment had greatest impact on pain improvement (P<0.01), and compared to Wangbi Tablets monotherapy, the combination of Wangbi tablets with WM or CM had larger associations with pain improvement (P<0.05); and Wangbi Tablets had better efficacy when the course of treatment was >28 days (P<0.01). Wangbi Tablets plus WM had a better effect on improving the overall function of the knee joint than Wangbi Tablets alone (P<0.01); and the efficacy of Wangbi Tablets with a course of treatment >28 days was better (P<0.05). The improvement of quality of life of patients in the attack and remission stages was more obvious than that in the recovery stage (P<0.01); Wangbi Tablets plus WM or CM had a better effect on improving quality of life than Wangbi Tablets alone (P<0.05). Before treatment, the proportion of patients with morning stiffness, soreness of waist and knees, fear of wind and chills in the monotherapy group was higher than that in the combination group (P<0.01). The proportion of main symptoms in both groups decreased after 4, 8 and 12 weeks of treatment (P<0.05). After 4 weeks of treatment, the disappearance rate of each main symptom in the combination group was higher than that in the monotherapy group, and after 12 weeks of treatment, the disappearance rate of fear of wind in the monotherapy group was higher than that in the combination group, while the disappearance rate of joint swelling and soreness of waist and knees was lower (P<0.05). ConclusionWangbi Tablets, whether used alone or in combination with other medications, is effective throughout the course of KOA, with greater benefits in improving joint function and quality of life during the acute and remission stages compared to the recovery stage. Combination therapy had a faster onset of effect, but began to converge with monotherapy after 8 weeks. The best efficacy was observed with the combination of Wangbi Tablets with WM, followed by combination with CM.
