Background At present, the treatment of silicosis is still limited, and no method is available to cure the disease. miRNAs are involved in the process of fibrosis at the transcriptional level by directly degrading target gene mRNA or inhibiting its translation. However, how miR-130a-3p regulates silicosis fibrosis has not been fully elucidated yet. Objective To investigate whether miR-130a-3p promotes epithelial-mesenchymal transition (EMT) by inhibiting peroxisome proliferators-activated receptors gamma (PPAR-γ), thereby pro-moting the process of silicotic fibrosis. To identify effective new targets for the treatment of silicotic fibrosis. Methods (1) Animal experiments: C57BL/6J mice were intratracheally injected with a one-time dose of 10 mg silica suspension (dissolved in 100 μL saline) as positive lung exposure. A silicosis model group was established 28 d after the exposure. A control group was injected with the same amount of normal saline into the trachea. Hematoxylin-eosin staining and Sirius red staining were used to observe the pathological changes and collagen deposition in lung tissues respectively. Realtime fluorescence-based quantitative polymerase chain reaction (RT-qPCR) was used to assay the expression of miR-130a-3p and PPAR-γ mRNA in lung tissues. Western blotting was used to detect the protein expression of PPAR-γ, transforming growth factor (TGF)-β1, E-cadherin, α-smooth muscle actin (α-SMA), and Collagen Ⅰ in lung tissues. (2) Cells experiments: Mouse lung epithelial cells (MLE-12) were induced with 5 µg·L−1 TGF-β1 for different time (0, 12, 24, 48 h). RT-qPCR was used to detect the expression of miR-130a-3p and PPAR-γ mRNA in cells. The binding relationship between miR-130a-3p and PPAR-γ mRNA was verified by dual luciferase reporter gene assay. MLE-12 cells were stimulated by 5 µg·L−1 TGF-β1 after transfection of miR-130a-3p inhibitor, and Western blotting was used to measure the protein expression of PPAR-γ, E-cadherin, and α-SMA in the TGF-β1-induced cells. Results In the silicosis model group, the alveolar septum was widened and the pulmonary nodules were formed. The Sirius red staining collagen deposition in pulmonary nodules indicated that a silicosis fibrosis model was successfully established. The expressions of TGF-β1, α-SMA, and Collagen Ⅰ proteins were increased, and the expressions of E-cadherin and PPAR-γ proteins were decreased in lung tissues of the silicosis group, compared with the control group (P<0.05 or P<0.01). The expression of miR-130a-3p was increased and the expression of PPAR-γ mRNA was decreased in lung tissues of the silicosis model (P<0.01). The expression of miR-130a-3p was significantly increased, while the expression of PPAR-γ mRNA was decreased in the TGF-β1 induced MLE-12 cells (P<0.05 or P<0.01). The dual luciferase reporter assay showed a direct relationship between miR-130a-3p and PPAR-γ mRNA in MLE-12 cells. The transfection of miR-130a-3p inhibitor in the TGF-β1 induced MLE-12 cells inhibited the decrease of PPAR-γ and E-cadherin proteins, and the increase of α-SMA protein in the MLE-12 cells induced by TGF-β1 (P<0.05 or P<0.01). Conclusion miR-130a-3p promotes the development of silicosis fibrosis by targeting PPAR-γ to increase pulmonary EMT.

To summarize Professor DING Ying's clinical experience in treating children's IgA nephropathy from the perspective of "wind-induced water turbidity". It is believed that the core pathogenesis of IgA nephropathy in children is the wind stimμlating water to become turbidity, and the basic treatment principles are to eliminate wind and settle viscera, and to remove turbidity and drain water. For those with the syndrome of wind-heat invading the lungs and injury to blood collaterals, modified Yinqiao Powder (银翘散) combined with Xiaoji Decoction (小蓟饮子) could be used; for those with dampness-heat in Sanjiao, heavy dampness and light heat pattern, modified Sanren Decoction (三仁汤) combined with Bazheng Powder (八正散) could be used; for those with lung-spleen qi deficiency and kidney essence depletion pattern, modified Buzhong Yiqi Decoction (补中益气汤) combined with Wuzi Yanzong Pill (五子衍宗丸) could be used; for those with deficiency of both qi and yin, kidney deficiency with stasis pattern, self-prescribed Yishen Huazhuo Formula (益肾化浊方) could be used. Meanwhile on the basis of pattern identification and treatment, rattan-type herbs could be combined in use in order to unblock the meridians and collaterals.

Background:
and Purpose Ruptured intracranial aneurysms (RIA) are associated with a mortality rate of up to 40% in the Chinese population, highlighting the critical need for targeted treatment interventions for at-risk individuals. Although the impact of aldehyde dehydrogenase 2 (ALDH2) gene mutations on susceptibility to intracranial aneurysms (IA) is well documented, the potential connection between ALDH2 rs671 single-nucleotide polymorphism (SNP) and RIA remains unexplored. Given the increased prevalence of ALDH2 gene mutations among Chinese Han individuals, it is clinically relevant to investigate the link between ALDH2 rs671 SNP and IA rupture.
Methods:
A prospective study was conducted on 546 patients diagnosed with IA to investigate the association between ALDH2 rs671 SNP and the risk of IA rupture.
Results:
The ALDH2 rs671 SNP (ALDH2*2) was significantly more prevalent in patients with unruptured IA (UIA) than in those with RIA (32.56% vs. 18.58%, P=0.004). Multivariate logistic regression analysis revealed that people with the ALDH2 mutation (ALDH2*1/*2 and ALDH2*2/*2 gene type) had a significantly reduced odds ratio (OR=0.49; 95% confidence level [CI] 0.27–0.88; P=0.018) for RIAs. Age-specific subgroup analysis indicated that the ALDH2 mutation provided a stronger protective effect in individuals aged 60 years and above with IA compared to those under 60 years old (OR=0.38 vs. OR=0.52, both P<0.05).
Conclusion
The incidence of RIA was significantly higher in individuals with a normal ALDH2 gene (ALDH2*1/*1) than in those with an ALDH2 rs671 SNP (ALDH2*1/*2 or ALDH2*2/*2). ALDH2 rs671 SNP may serve as a protective factor against RIA in the Chinese Han population.

Based on the theory of "spleen functions as wei qi", this paper believes that the disease mechanism of allergic rhinitis (AR) in children is the nasal dysfunction caused by the loss of spleen's wei qi. The root cause of AR is the failure of splenic transportation as well as its inability to properly distribute nutrients. The inducement of AR is the invasion of pathogenic qi coupled with insecurity of the wei exterior. The key to AR recurrence lies in the deficiency of healthy qi and lingering of pathogenic qi, with pathogenic qi lodging inside the body. The treatment should adhere to the principle of helping the spleen restore wei qi. During the acute phase, the treatment should dispel wind, conso-lidate the wei qi, and relieve stuffy orifices, and the modified Qufeng Tongqiao Decoction (祛风通窍汤) is used. During the remission phase, the treatment should fortify the spleen, raise the clear, and harmonize the wei qi, and the modified Yuhan Decoction (御寒汤) is applied. During the recovery phase, the treatment should reinforce the healthy qi, consolidate the constitution, and strengthen the wei qi, and the modified Huangqi Jianzhong Decoction (黄芪建中汤) is employed.

ObjectiveTo analyze the clinical and epidemiological characteristics of confirmed cases of human monkeypox infection in Changning District, Shanghai, and to explore their clinical and epidemiological characteristics. MethodsClinical data from 10 reported cases of monkeypox in individuals residing in Changning District or identified by local medical institutions between July 20 and September 30, 2023, were collected. Epidemiological case investigations were conducted, and throat swabs, anal swabs, and rash swabs were collected by the treating medical institutions. Real-time fluorescence quantitative PCR was used for monkeypox virus nucleic acid testing, and descriptive epidemiological analysis was applied to analyze the epidemiological characteristics of the cases. ResultsAll 10 confirmed cases of human monkeypox infection were all young males with an average age of 35.4 years, all of whom belonged to the men who have sex with men (MSM) population, with no occupational clustering. The primary clinical symptoms included fever, rash, enlarged inguinal lymph nodes, and muscle soreness. Nine cases presented with a rash, and seven cases experienced fever symptoms. Among the 10 cases, one experienced fever, rash, enlarged lymph nodes, and muscle soreness; two had fever, rash, and enlarged lymph nodes; two had fever, rash, and systemic soreness; two had only a rash; one had fever or rash; and one was asymptomatic. Among the nine cases with a rash, the rash was mainly localized to the genital or anal area, with fewer cases presenting rashes on the limbs or trunk simultaneously. All cases reported a history of non-exclusive MSM behavior within 21 days before the onset of the disease. The interval between the last suspected high-risk exposure and the onset of symptoms was 4 to 10 days, with an average interval of 6.9 days. The time from the onset of fever to the appearance of a rash was 0 to 5 days, with an average of 1.87 days. ConclusionThe main clinical manifestations of human infection with monkeypox are fever, rash, and enlarged inguinal lymph nodes. The MSM population is a high-risk group for monkeypox infection, and its source of infection may be associated with MSM exposure. Early-stage symptoms are mild, leading to potential underdiagnosis. Additionally, patients may conceal information during the investigation process, which increases the difficulty of epidemic prevention and control.

ObjectiveTo explore the therapeutic mechanism of Faeces Bombycis on diabetic gastroparesis (DGP) rats based on phosphatidylinositol 3-kinase/protein kinase B/mammalian rapamycin target protein (PI3K/Akt/mTOR) signaling pathway. MethodDGP rat model was prepared by random selection of 15 out of 105 rats as blank group. The rats successfully constructed were randomly divided into model group, high-,medium- and low- dose groups (3.2, 1.6, 0.8 g·kg-1) and moxapride group (1.5 mg·kg-1), with 12 rats in each group, and were given gavage for 4 weeks. The gastric emptying rate and random blood glucose were measured. The morphological changes of gastric antrum were observed by hematoxylin-eosin (HE) staining, and the expression of the c-Kit gene was analyzed by immunohistochemistry. The apoptosis of Cajal interstitial cells was observed by in situ end labeling (TUNEL) staining, and the protein expressions of PI3K, phosphorylation(p)-PI3K, Akt, p-Akt, mTOR, and p-mTOR were detected by Western blot. ResultCompared with the blank group, the gastric emptying rate of the model group decreased significantly (P<0.01), and the glandular structure of the gastric antrum was destroyed. The expression of c-Kit decreased (P<0.01), and the apoptosis of Cajal interstitial cells (ICC) increased. Compared with the model group, the gastric emptying rate in the high, middle, and low-dose groups of Faeces Bombycis extract and mosapride group increased significantly (P<0.01). The glandular structure of the gastric antrum became closer, and the apoptosis of ICC decreased. The expression of c-Kit in the high dose group of Faeces Bombycis extract increased significantly. After Western blot testing, compared with the blank group, the protein expression of p-Akt/Akt, p-PI3K/PI3K, and p-mTOR/mTOR in the model group increased. Compared with the model group, the protein expression of p-Akt/Akt in the high dose group of Faeces Bombycis extract decreased (P<0.01), and the protein expression of p-PI3K/PI3K decreased in the middle and low dose groups of Faeces Bombycis extract and mosapride group decreased (P<0.05, P<0.01). The protein expression of p-mTOR/mTOR decreased in the low dose group of Faeces Bombycis extract (P<0.05). In terms of random blood glucose, compared with the blank group, the random blood glucose in the model group increased significantly (P<0.01), and compared with the model group, the random blood glucose in the high and middle dose groups of Faeces Bombycis extract decreased significantly (P<0.05). Compared with mosapride group, the protein expression of p-Akt/Akt decreased in the high dose group of Faeces Bombycis extract (P<0.05), and the protein expression of p-PI3K/PI3K increased in the high, middle, and low dose groups of Faeces Bombycis extract (P<0.05, P<0.01). ConclusionFaeces Bombycis extract can increase gastric emptying rate, reduce ICC apoptosis, and lower random blood glucose in DGP rats. The high dose group of Faeces Bombycis extract has a significant effect on inhibiting ICC apoptosis, and its mechanism may be related to the regulation of the PI3K/Akt/mTOR signaling pathway.

Tic disorder (TD) is a neurodevelopmental disorder. According to the core symptoms,it can be classified as "liver wind","wind syndrome",and "concurrent". The clinical syndrome of TCM is based on wind,and the pathogenesis is based on the liver. However,the clinical symptoms of this disease are relatively complicated. Based on the " manifestation-qi transformation" theory,this study further explores the liver wind,lung wind,heart wind,spleen wind,and kidney wind from the pathological basis of intrinsic wind rash movement and proposes that the liver wind caused by hyperactivity of liver yang is the main cause of intrinsic wind rash movement in TD,and the lung wind caused by lung loss is the main cause. The liver is related to the heart,spleen,and kidney. Together,the five-wind affect the onset,development,and outcome of TD. Based on this understanding of the pathogenesis,it is necessary to identify the specific syndromes of the patients. The five-wind differentiation and treatment system uses the method of calming the liver and dispelling the lungs to treat the root of the internal wind rash movement. Xiaochaihu Decoction,Sangju Decoction,Cang'erzi Powder,and other prescriptions can be used with modification and subtract and use method of controlling heart fire,transporting spleen soil,and nourishing kidney water to treat derived images. Meanwhile,Xieqing Pill,Daochi Powder,Yigong Powder,Erchen Decoction,Liuwei Dihuang Pill,and other prescriptions can be used with modification.

Objective:To evaluate the efficacy and safety of hypomethylating agents (HMA) in patients with myelodysplastic syndromes (MDS) .Methods:A total of 409 MDS patients from 45 hospitals in Zhejiang province who received at least four consecutive cycles of HMA monotherapy as initial therapy were enrolled to evaluate the efficacy and safety of HMA. Mann-Whitney U or Chi-square tests were used to compare the differences in the clinical data. Logistic regression and Cox regression were used to analyze the factors affecting efficacy and survival. Kaplan-Meier was used for survival analysis. Results:Patients received HMA treatment for a median of 6 cycles (range, 4-25 cycles) . The complete remission (CR) rate was 33.98% and the overall response rate (ORR) was 77.02%. Multivariate analysis revealed that complex karyotype ( P=0.02, OR=0.39, 95% CI 0.18-0.84) was an independent favorable factor for CR rate. TP53 mutation ( P=0.02, OR=0.22, 95% CI 0.06-0.77) was a predictive factor for a higher ORR. The median OS for the HMA-treated patients was 25.67 (95% CI 21.14-30.19) months. HMA response ( P=0.036, HR=0.47, 95% CI 0.23-0.95) was an independent favorable prognostic factor, whereas complex karyotype ( P=0.024, HR=2.14, 95% CI 1.10-4.15) , leukemia transformation ( P<0.001, HR=2.839, 95% CI 1.64-4.92) , and TP53 mutation ( P=0.012, HR=2.19, 95% CI 1.19-4.07) were independent adverse prognostic factors. There was no significant difference in efficacy and survival between the reduced and standard doses of HMA. The CR rate and ORR of MDS patients treated with decitabine and azacitidine were not significantly different. The median OS of patients treated with decitabine was longer compared with that of patients treated with azacitidine (29.53 months vs 20.17 months, P=0.007) . The incidence of bone marrow suppression and pneumonia in the decitabine group was higher compared with that in the azacitidine group. Conclusion:Continuous and regular use of appropriate doses of hypomethylating agents may benefit MDS patients to the greatest extent if it is tolerated.
