Rheumatoid arthritis （RA） is a chronic systemic autoimmune disease characterized by symmetrical polyarthritis， which may lead to joint deformity and loss of joint function in the long term， severely impairing patients' quality of life. Danggui Niantongtang， originated from Medical Revelations by Zhang Yuansu in the Jin Dynasty， has the effects of clearing heat and draining dampness， dispelling wind and alleviating pain， and serves as a classic formula for treating RA damp-heat stagnation syndrome. By searching CNKI， Wanfang， PubMed and other databases， the author systematically reviewed the clinical efficacy and experimental research of Danggui Niantongtang in the treatment of RA， and elucidated its mechanisms of action， so as to provide a valuable reference for future clinical and basic research of Danggui Niantongtang in the field of RA. Clinical studies demonstrated that Danggui Niantongtang can improve core symptoms in RA patients with the damp-heat stagnation syndrome， including joint swelling and pain， morning stiffness and limited joint mobility， decrease inflammatory markers such as C-reactive protein （CRP） and erythrocyte sedimentation rate （ESR）， and facilitate postoperative rehabilitation in RA patients undergoing total knee arthroplasty （TKA）. When combined with Western medicines such as methotrexate， it can enhance the anti-inflammatory efficacy and mitigate adverse reactions， including gastrointestinal discomfort and hepatic injury. Experimental studies revealed that this formula can modulate the inflammatory cytokine network， promote synoviocyte apoptosis， inhibit abnormal synoviocyte autophagy， suppress synovial angiogenesis， and maintain intestinal flora homeostasis. However， several limitations exist in current research， such as insufficient clinical quality， unclear interaction between mechanisms and networks， and insufficient research on dosage form optimization. In the future， high-quality clinical research， multi-omics mechanistic studies， and dosage form improvement are needed to provide scientific basis for its clinical promotion and in-depth research.

OBJECTIVE To compare the antihypertensive efficacy of sacubitril/valsartan versus benazepril in patients with perimenopausal hypertension， as well as their impacts on ventricular remodeling and inflammatory fibrosis. METHODS A total of 206 perimenopausal hypertensive patients in our hospital from January 1， 2023 to December 30， 2024 were retrospectively included.These patients were enrolled and divided into benazepril group （105 cases） and sacubitril/valsartan group （101 cases）. Benazepril group received Benazepril hydrochloride tablet， and sacubitril/valsartan group received Sacubitril valsartan sodium tablet. All patients were treated for 6 months. The blood pressure（systolic blood pressure and diastolic blood pressure） and blood pressure control status before and after treatment， echocardiographic indicators （left ventricular ejection fraction， left ventricular mass index， relative wall thickness， and early-diastolic peak transmitral flow velocity/early-diastolic peak velocity of the mitral annulus）， inflammatory fibrosis related indicators（high-sensitivity C-reactive protein，ratio of monocytes to lymphocytes，and ratio of neutrophils to lymphocytes）， as well as the occurrence of adverse reactions（hypotension，hyperkalemia，and angioedema） were observed in both groups before and after treatment. RESULTS The blood pressure control rate was significantly higher in the sacubitril/valsartan group than in benazepril group （ P ＜0.05）. After treatment， the blood pressure， echocardiographic indicators（except for left ventricular ejection fraction） ，and inflammatory fibrosis related indicators were significantly lower than those before treatment within the same group， and the sacubitril/valsartan group were significantly lower than the benazepril group （ P ＜0.05）. There were no statistically significant differences in the incidence of hypotension， hyperkalemia， angioedema， and overall adverse drug reactions between the two groups （ P ＞0.05）. CONCLUSIONS Compared with benazepril， sacubitril/valsartan provides superior blood-pressure control， reverses ventricular remodeling， attenuates inflammatory fibrosis in perimenopausal hypertensive patients， while maintaining a similar safety profile.

BACKGROUND:Collagen combined with microneedling therapy has gradually become an important means of improving skin photoaging.OBJECTIVE:To summarize and explore the main mechanism and clinical application status of collagen combined with microneedle therapy.METHODS:PubMed,China National Knowledge Infrastructure,and ScienceDirect databases were searched for Chinese and English literature published before August 2024.Chinese and English search terms were"ultraviolet radiation,photoaging,collagen,microneedling,clinical applications."Finally,74 articles were included for summary.RESULTS AND CONCLUSION:Collagen treats skin photoaging through mechanisms such as inhibiting matrix metalloproteinase expression,retaining skin moisture,and reducing melanin formation.Microneedles can better promote the penetration of collagen into deep layers of the skin,breaking down the skin's barrier and increasing the absorption rate.Collagen combined with microneedles has various beneficial effects for treating skin photoaging,such as whitening,anti-wrinkle,improving skin elasticity,shrinking pores,and repairing skin barriers.It also has the advantages of easy operation,significant effects,and high safety.Currently,the research on collagen combined with microneedling therapy is still in its early stages,and achieving clinical application may become a key research direction in the future.The clinical application of collagen combined with microneedles for the treatment of photoaging still faces many challenges,such as exploring the optimal mechanical structure and materials of microneedles,selecting appropriate microneedle types,and insufficient clinical evidence that collagen combined with microneedles can further delay the treatment of skin photoaging.

OBJECTIVE To discuss the effect mechanism of atractylodin （ATR） on lung injury and airway inflammation in rats with acute exacerbation of chronic obstructive pulmonary disease （AECOPD）. METHODS AECOPD model was established using smoke exposure and intratracheal injection of lipopolysaccharide. Rats were randomly grouped into model group， ATR low-， medium- and high-dose groups （25， 50 and 100 mg/kg）， as well as high-dose ATR+anisomycin [ANS， c-Jun N-terminal kinase （JNK） activator] group （100 mg/kg ATR+5 mg/kg ANS）. Additionally， a non-modeled control group was set up， with 12 rats in each group. Rats in each group were intraperitoneally injected with the corresponding drug solution/normal saline once daily for 14 consecutive days. After the last medication， lung function [peak expiratory flow （PEF）， the ratio of forced expiratory volume （FEV） to forced vital capacity （FVC）， arterial partial pressure of oxygen （PaO2）]， as well as the number of inflammatory cells and the levels of inflammatory cytokines [interleukin-6 （IL-6）， tumor necrosis factor-α （TNF-α）， and IL-1β] in bronchoalveolar lavage fluid （BALF）， were measured. The pathological morphology of lung tissue in rats was observed. 163.com The apoptosis of lung epithelial cells was detected， and the expression levels of proteins related to the JNK/p38 mitogen-activated protein kinase （p38 MAPK） signaling pathway in rat lung tissues were detected. RESULTS Compared with control group， PEF， FEV/FVC and PaO2 of model group were slowed or decreased significantly （P＜0.05）. The number of white blood cells， neutrophils， lymphocytes and macrophages， as well as the levels of IL-1β， TNF-α and IL-6 in BALF， along with the pathological score， the apoptosis rate of lung epithelial cells， and the phosphorylation levels of JNK and p38 MAPK proteins in lung tissues， were all increased or raised significantly （P＜0.05）； lung tissue exhibited severe damage， with disordered cell arrangement and marked infiltration of inflammatory cells. Compared with model group， the levels of above quantitative indicators in rats from all ATR dosage groups showed significant improvement in a dose-dependent manner （P＜0.05）； moreover， the pathological damage in lung tissue was alleviated， with cells arranged in a regular and orderly fashion. Compared with ATR high-dose group， the levels of the above quantitative indicators in rats from the high-dose ATR+ANS group were significantly reversed （P＜0.05）， and the pathological damage in lung tissue was exacerbated. CONCLUSIONS ATR inhibits airway inflammation by suppressing the activity of the JNK/p38 MAPK signaling pathway， thereby improving lung tissue damage in AECOPD rats.

Objective To investigate the relationship between the expression of serum long non coding RNA nuclear-enriched abundant transcript 1(lncRNA NEAT1)and microRNA-106a-5p(miR-106a-5p)and the severity and prognosis of sepsis patients.Methods A total of 185 patients with sepsis who were diagnosed and treated in this hospital from August 2021 to July 2024 were selected as the study group,and another 215 healthy volunteers who underwent physical examinations in this hospital during the same period were selected as the control group.The research group was divided into the mild group(n=92),the severe group(n=58)and the shock group(n=35)according to the severity of the disease.The research group was divided into the good prognosis group(n=121)and the poor prognosis group(n=64)according to the prognosis.The expres-sions of lncRNA NEAT1 and miR-106a-5p were detected by real-time fluorescence quantitative polymerase chain reaction,and the correlation of the expressions of lncRNA NEAT1 and miR-106a-5p in the study group was analyzed by Pearson correlation analysis.The binding sites of lncRNA NEAT1 and miR-106a-5p were an-alyzed by StarBase,and the influencing factors of poor prognosis in patients were analyzed by multivariate Lo-gistic regression.The receiver operating characteristic curve was used to analyze the diagnostic value of the combination of lncRNA NEAT1 and miR-106a-5p for poor prognosis in patients.Results The expression of lncRNA NEAT1 in the study group was higher than that in the control group,and the expression of miR-106a-5p was lower than that in the control group,the difference was statistically significant(P＜0.05).The expressions of lncRNA NEAT1 and miR-106a-5p in the study group were negatively correlated(r=-0.413,P＜0.001),and there were binding sites between the two.With the increase of the severity of sepsis,the ex-pression of lncRNA NEAT1 increased and the expression of miR-106a-5p decreased,and the difference was statistically significant(P＜0.05).The acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ)score,sequential organ failure assessment(SOFA)score,tumor necrosis factor-α,C-reactive protein,and ln-cRNA NEAT1 in the poor prognosis group were higher than those in the good prognosis group,while the ex-pression of miR-106a-5p was lower than that in the good prognosis group,the difference was statistically sig-nificant(P＜0.05).Elevated APACHE Ⅱ score,SOFA score and lncRNA NEAT1 were independent risk fac-tors for poor prognosis in patients,and miR-106a-5p was an independent protective factor(P＜0.05).The ar-ea under the curve of the combined diagnosis of the two was 0.918(95％CI:0.868-0.953),which was supe-rior to the separate diagnosis of each(Zcombined with lncRNA NEAT1=4.112,Zcombined with miR-106a-5p=4.023,P＜0.05).Con-clusion With the increase of disease severity in patients with sepsis,the expression of lncRNA NEAT1 in-creases and the expression of miR-106a-5p decreases.The combined diagnosis of the two for poor prognosis in patients has a high clinical value.

Objective: To investigate the trend in reported incidence of hepatitis B and to assess the effects of age, period, and birth cohort among people aged <30 years in Quzhou City, Zhejiang Province from 2005 to 2024. Methods: Reported cases of hepatitis B among people aged <30 years in Quzhou City from 2005 to 2024 were collected from the Infectious Disease Reporting Information System of Chinese Disease Prevention and Control Information System. The reported incidence was calculated. The average annual percent change (AAPC) was used to analyze the trend in reported incidence from 2005 to 2024. An age-period-cohort model was employed to analyze the effects of age, period, and birth cohort on the reported incidence of hepatitis B. Results: From 2005 to 2024, a total of 3 805 hepatitis B cases were reported among people aged <30 years in Quzhou City, with an average annual reported incidence of 31.61/100 000. The average annual reported incidence of hepatitis B was higher in males than in females (36.65/100 000 vs. 26.08/100 000, P<0.05). From 2005 to 2024, the reported incidence of hepatitis B among the entire people aged <30 years, as well as among males and females separately in Quzhou City, showed declining trends (AAPC=-9.887%, -10.415%, and -9.320%, respectively, all P<0.05). The age-period-cohort model analysis revealed that the incidence first decreased and then increased with age, declining from 4.21/105 in the age group of 0-<5 years to 2.07/105 in the age group of 10-<15 years, before rising to 22.49/105 in the age group of 25-<30 years. Using the 2010-2014 period as the reference, the risk of hepatitis B showed a decreasing trend over time. The RR value decreased from 1.842 (95%CI: 1.433-2.366) for 2005-2009 to 0.446 (95%CI: 0.294-0.675) for 2020-2024. Using the 2000-2004 birth cohort as the reference, the risk showed a decreasing trend with more recent birth years. The highest risk was observed in the 1980-1984 birth cohort, with an RR value of 4.731 (95%CI: 3.083-7.259). The age, period, and cohort effects on the reported incidence of hepatitis B among males and females were generally consistent with those observed in the entire population. Conclusions From 2005 to 2024, the reported incidence of hepatitis B among people aged <30 years in Quzhou City showed a declining trend, while exhibiting a pattern of first decreasing and then increasing with age. Furthermore, the risk of hepatitis B incidence demonstrated a decreasing trend over both time periods and birth cohorts.
