Synovium is the target organ of rheumatoid arthritis.The excessive proliferation of synovial cells and insufficient apoptosis lead to synovial hyperplasia,which in turn causes damage to the surrounding tissues of the joint and bone destruction."Yang transforming qi and yin forming elements"is derived from Su Wen and is a highly summarized description of the functions of yin and yang,which runs through the entire course of the disease.This article elucidated the theoretical connotation of"yang transforming qi and yin forming elements"and its connection with synovial hyperplasia,proposing that the insufficiency of"yang transforming qi"is the root of synovial hyperplasia,while the excess of"yin forming elements"is the manifestation of synovial hyperplasia.Based on this,it put forward that"assisting yang qi as the priority,and according to the bias of pathogenic factors of yin,supplementing the method of reducing yin forming elements"is an important principle for treating this disease,which could provide new ideas for the treatment of the disease.

Objective:To evaluate the diagnostic performance of fecal calprotectin (FC) in predicting endoscopic activity of ulcerative colitis (UC), and to compare it with high-sensitivity C reactive protein (hsCRP) and erythrocyte sedimentation rate (ESR) .Methods:A cross-sectional stydy was conducted. UC patients diagnosed at Peking Union Medical College Hospital between May 2023 and July 2025 were retrospective enrolled. Patients were divided into the endoscopically active group and endoscopic remission group according to endoscopic activity. FC levels were measured using latex-enhanced turbidimetric immunoassay (LETIA). Receiver operating characteristic (ROC) curves and logistic regression models were used to assess diagnostic efficacy. Subgroup analyses were conducted according to disease extent.Results:A total of 166 UC patients were enrolled, including 92 males and 74 females with the age of 40.00 (32.00, 52.00) years old and disease course 5.00 (2.00, 10.75) years. Forty-six patients were assigned to the active group, while the remaining 120 were assigned to the remission group. FC levels were significantly higher in the active group than in the remission group (620.72 μg/g vs. 29.00 μg/g, P < 0.001), with an AUC of 0.894 at a cutoff value of 122.54 μg/g. hsCRP and ESR had lower AUC (0.712 and 0.736, respectively). The combination of FC, hsCRP, and ESR slightly improved specificity (AUC 0.898). FC was strongly correlated with the endoscopic activity ( r =0.669, P < 0.001) but not with disease extent. Conclusions:FC measured by latex-enhanced turbidimetric immunoassay had comparable diagnostic accuracy to ELISA-based methods commonly used abroad, and provided a reference cutoff value of 122.54 μg/g. FC outperforms hsCRP and ESR in assessing intestinal inflammation in UC and it is less affected by disease extent, making it a reliable non-invasive biomarker for UC monitoring.

Objective:To evaluate the predictive efficacy of fecal calprotectin (FC) for endoscopic activity in patients with Crohn's disease (CD) .Methods:A cross-sectional study was conducted and patients diagnosed as CD at Peking Union Medical College Hospital from June 2023 to September 2025 were enrolled consecutively. Data was collected including general information, laboratory tests [hemoglobin (HGB), platelet (PLT), FC, high-sensitivity C-reactive protein (hsCRP), erythrocyte sedimentation rate (ESR) and so on], and endoscopic results. FC levels were measured by latex-enhanced turbidimetric immunoassay (LETIA). Endoscopic activity was defined as the simplified endoscopic score for Crohn's disease (SES-CD) > 2. Patients were divided into the endoscopically active group and endoscopic remission group according to endoscopic activity, and the differences in clinical data between the two groups were compared. Spearman correlation analysis was used to assess the correlation between FC and endoscopic activity, and receiver operating characteristic (ROC) curve was used to evaluate the predictive efficacy of FC, hsCRP and ESR for endoscopic activity, and the differences were compared.Results:A total of 90 CD patients were enrolled, including 65 males and 25 females with the age of 30 (22, 41) years old and disease course 4.0 (0.5, 8.0) years. Seventy-one patients (78.9%) had ileocolonic disease involvement (L3), and 55 patients (61.1%) were using biologics. Sixty-nine patients in endoscopic active phase were assigned to the endoscopically active group, while the remaining 21 were assigned to the endoscopic remission group. There were no statistically significant differences in general characteristics such as age and gender between the two groups (all P > 0.05). Compared with endoscopic remission group, HGB was significantly lower in the endoscopically active group, while PLT, hsCRP, ESR, and FC were moderataly higher (all P < 0.05). Among the 90 CD patients, FC levels were moderatly correlated with endoscopic activity (ρ = 0.494). ROC curve analysis indicated that the area under the curve for FC in predicting endoscopic activity was 0.836 (95% CI: 0.737-0.935), with a sensitivity of 0.725, specificity of 0.952, and accuracy of 0.778 at the optimal FC cutoff value of 153.8 μg/g. FC outperformed hsCRP and ESR. Conclusion:FC measured by LETIA demonstrates certain efficacy in predicting endoscopic activity in CD and will assist in efficient clinical monitoring of CD patients.

In this study, we constructed a series of recombinant Fc variants of immunoglobulin G4 (IgG4), screened the fragment crystallizable (Fc) variants with significantly prolonged serum half-lives, and analyzed the relationship between mutation site and half-life, aiming to provide a theoretical basis for the development of IgG4 antibodies and Fc fusion protein-based drugs. Nine gene sites were selected for mutation, and different mutation sites were combined. The variant expression plasmids pET24b-Fc were constructed by molecular cloning and point mutation. The plasmids were transformed into Escherichia coli BL21(DE3) for the expression of different recombinant proteins of Fc. Fc2 and Fc3 variants had slightly lower recombinant protein yields, and the expression of other variants was not affected. The toxicity of different Fc variants was determined by cell counting kit-8 (CCK-8) and calcein acetoxymethyl ester/ propidium iodide (calcein AM/PI) in vitro and enzyme-linked immuno sorbent assay (ELISA) in vivo. The results showed that the recombinant Fc variants had good biocompatibility and safety. Finally, the Fc variants were labeled with fluorescent markers, and the effects of different mutations on their serum half-lives were investigated by in vivo experiments. The Fc5 variant with prolonged serum half-life was successfully screened out, which provided a theoretical and practical basis for the optimal design of IgG4 subtype antibody and Fc fusion protein drugs.

People with AIDS are highly prone to opportunistic infections,among which pulmonary infections are the most common,with high incidence and fatality rates.How to effectively prevent or reduce the occurrence of HIV-related lung infections(HRLI)is of great practical significance.From the perspective of traditional Chinese medicine(TCM),HRLI and AIDS share common pathological mechanisms,including qi deficiency,spleen defi-ciency,phlegm-heat or phlegm-dampness obstructing the lungs.Based on the TCM theory of"preventing disease before it occurs",the three-level prevention approach includes:the first step"preventing disease before it occurs"emphasizes strengthening the body's defense mechanisms by tonifying the spleen and benefiting qi,and nourishing the lungs and kidneys to strengthen the exterior and protect the body;the second step"preventing the progression of disease once it occurs"emphasizes the removal of pathogenic factors while strengthening the body's defenses.Based on the principles of syndrome differentiation and treatment in TCM,focuses are kept on the spleen tonifying and phlegm resolving,pathogenic factors dispelling and dampness eliminating,while protecting the spleen and nourishing other organs.The third step"preventing relapse after recovery"emphasizes replenishing deficiencies and enhancing immunity.Adopting the three-level prevention approach and early intervention can reduce the inci-dence of HRLI,which is a new idea for the prevention and treatment of HRLI with TCM.

Objective:To analyze the correlation between respiratory event duration and nocturnal oxygen saturation (SpO 2) in adults with obstructive sleep apnea (OSA), and to explore its significance in assessing nocturnal hypoxemia and OSA severity. Methods:A prospective study was conducted on adult OSA patients diagnosed via overnight standard polysomnography (PSG) at the Department of Otolaryngology, First Affiliated Hospital of Sun Yat-sen University from June 2019 to December 2023. Data collected included demographic information, PSG reports, scale scores, and comorbidities. Patients were first stratified by apnea-hypopnea index (AHI) severity. Relationships between respiratory event duration parameters,including total apnea-hypopnea time (TAHT), percentage of total sleep time with apnea-hypopnea (AHT%), total apnea time (TAT), total hypopnea time (THT), and mean apnea-hypopnea time (MAHT), and nocturnal SpO? parameters, including average SpO? (aSpO?), minimal SpO? (mSpO?), mean oxygen desaturation (MOD), and percentage of total sleep time with SpO?<90% (CT90), were analyzed. Patients were then divided into two groups based on the median MAHT (27.6 s) for SpO? comparison. Finally, severe OSA patients were further subclassified using an AHI inflection point (50 events/h) identified via scatter plot analysis to compare nocturnal SpO?. Statistical analysis was performed using SPSS 27.0.Results:Among the 250 study subjects, there were 201 males and 49 females, with ages ranging from 18 to 76 years (mean age: 41.6 ± 11.9 years).TAHT, AHT%, and TAT in OSA patients demonstrated significant negative correlations with aSpO?( r=-0.698, -0.718, -0.646)and mSpO?( r=-0.746, -0.746, -0.748), while showing positive correlations with MOD ( r=0.783, 0.791, 0.823)and CT90 ( r=0.868, 0.866, 0.852), P<0.05. When stratified by MAHT median ( M=27.6 s), the "long-event" subgroup ( n=125) displayed significantly lower mSpO 2 and higher MOD and CT90 compared to the "short-event" subgroup ( n=125), Z=-3.319, 3.288, 2.242; P<0.05. No significant difference in aSpO 2 was observed ( P>0.05). Subgrouping severe OSA patients at AHI=50 events/hour revealed significant differences in aSpO 2, mSpO 2, MOD, and CT90 between groups ( Z=-5.011, -4.787, 5.142, 6.117, P<0.05). Conclusions:TAHT, AHT%, and TAT significantly correlate with nocturnal SpO? parameters in OSA patients and can supplement AHI in assessing OSA severity. MAHT independently reflects nocturnal oxygenation status beyond AHI.
