Shengjiangsan is a classic formula for treating warm diseases with wide clinical application and accurate efficacy. There are different opinions on the origin of this formula and lacks key information research on this formula. Therefore, in this study, we conducted systematic research into the historic origin, composition, and other key information of this Shengjiangsan. Results showed that Shengjiangsan has different versions, with "Neixian Fufang", "Jiawei Jianghuangwan", "Peizhensan", and "Taijiwan" being the same formula with different names. Shengjiangsan was first recorded as "Neixian Fufang" in Wanbing Huichun written by GONG Tingxian from the Ming dynasty, inherited and developed by YANG Lishan from Qing dynasty, and has been passed down to modern times. Pills and powder are two main forms of Shengjiangsan, and powder has become more popular nowadays. According to the measurement system of Ming and Qing dynasties, the recommended dosage and usage of Shengjiangsan are as follows. For the pill version of Shengjiangsan, Bombyx Batryticatus of 74.6 g, Curcumae Longae Rhizoma of 9.325 g, Cicadae Periostracum of 9.325 g, and Rhei Radix et Rhizoma of 149.2 g were processed into pills for preparation. Single dosage is Bombyx Batryticatus of 1.15 g, Curcumae Longae Rhizoma of 0.14 g, Cicadae Periostracum of 0.14 g, and Rhei Radix et Rhizoma of 2.3 g, with halved dosage applied for children. For the powder version of Shengjiangsan, the dosage varied in accordance with the severity of the disease. Bombyx Batryticatus of 1.84 g, Curcumae Longae Rhizoma of 0.28 g, Cicadae Periostracum of 0.92 g, and Rhei Radix et Rhizoma of 3.68 g were processed into powder for patients with mild symptoms. Bombyx Batryticatus of 2.48 g, Curcumae Longae Rhizoma of 0.37 g, Cicadae Periostracum of 1.23 g, and Rhei Radix et Rhizoma of 4.91 g were processed into powder for patients with severe symptoms. Bombyx Batryticatus of 3.68 g, Curcumae Longae Rhizoma of 1.84 g, Cicadae Periostracum of 0.55 g, and Rhei Radix et Rhizoma of 7.36 g were processed into powder for patients with critical conditions. In this formula, four herbs were ground to fine powder. For patients with mild symptoms, the whole formula was divided into four dosages, and each dosage weighed 6.71 g. The 200 mL yellow rice wine and 18.65 g honey were added, and the solution was stirred and taken cold till full recovery. For patients with severe symptoms, the whole formula was divided into three dosages, and each weighed 8.95 g. 300 mL yellow rice wine and 27.98 g honey were added, and the solution was stirred and taken cold. For patients with critical conditions, the whole formula was divided into two dosages, and each weighed 13.43 g. 400 mL yellow rice wine and 37.3 g honey were added, and the solution was stirred and taken cold. Shengjiangsan has the effect of ascending lucidity and descending turbidity, dissipating wind, and clearing heat. It is specialized in treating severe heat in exterior, interior, and triple energizers in warm diseases and has a wide modern clinical application. In this study, the historic evolution and key information of Shengjiangsan were reviewed and analyzed, and the key information table of Shengjiangsan was attached, serving as a reference for scholars' research and a theoretical basis for its market transformation.

Idiopathic pulmonary fibrosis (IPF) can be classified as pulmonary collateral disease,and its pathogenesis is mainly characterized by the loss of Qi meridian nourishment,the loss of Yin meridian nourishment,and the formation of blood stasis in the blood vessels. Qi Yin deficiency is the pathological basis that runs through IPF,and obstruction of meridians and collaterals is a key element in the development of the disease. The dysfunction of "spleen being in charge of the defensive function" is closely related to the formation of the pathological pattern of "lung deficiency and collateral stasis" in IPF. The term "spleen being in charge of the defensive function" originated from the Yellow Emperor's Inner Canon. If the spleen is healthy,the Qi will be filled with vitality. Positive energy is stored inside,evil cannot be dried up. Its concept is quite similar to the immune defense function in modern medicine. If the principle of "spleen being in charge of the defensive function" is lost,the key structure and function of the IPF alveolar epithelial barrier may be abnormal,and it can interact with various innate immune cells to promote inflammation and fibrosis processes. Therefore,this article explains the imbalance of immune homeostasis in IPF alveolar epithelium from two aspects:the barrier function of alveolar epithelial cells(AECs) and their interaction with innate immune cells. And based on the theory of "spleen being in charge of the defensive function",using traditional Chinese medicine for strengthening the spleen and nourishing Qi to treat IPF from the perspective of the spleen. This not only strengthens the scientific connotation of "spleen being in charge of the defensive function" in the pathogenesis of IPF,but also provides new research directions and ideas for its future clinical prevention and treatment.

ObjectiveThis paper aims to systematically collect and organize ancient and modern clauses and studies containing Xieqingwan, excavate and analyze the key information of Xieqingwan, and provide a reference for facilitating the development of the classic formula Xieqingwan. MethodsThe composition, dosage, decocting methods, usage, and other key information of Xieqingwan in ancient traditional Chinese medicine books were collected and analyzed by means of literature research and metrological methods. The modern clinical application of Xieqingwan was summarized. ResultsA total of 42 pieces of effective data involving 32 ancient traditional Chinese medicine books were collected. Xieqingwan was first recorded in Xiaoer Yaozheng Zhijue. The drug origin of this formula is basically clear in the ancient traditional Chinese medicine books. The modern drug usage and decocting method were as follows: Angelicae Sinensis Radix, Gentianae Radix et Rhizoma, Chuanxiong Rhizoma, Gardenia seeds, Radix et Rhizoma Rhei, Notopterygii Rhizoma et Radix, and Saposhnikoviae Radix were grounded to fine powder, decocted with honey, and finally formed into pills with the size of a chicken head (1.5 g). It was suggested that half a pill or one pill were taken for one dose with warm Lophatheri decoction and sugar. The indications and clinical application had developed from the recordings in Xiaoer Yaozheng Zhijue and evolved from pediatrics to ophthalmic otolaryngology, neurology, dermatology, digestion, and respiratory diseases. The main pathogenesis of these diseases is heat in the liver meridian and is treated. The effect of Xieqingwan is "clearing away heat and toxicity, removing fire and relaxing the bowels, and dispersing swelling and relieving pain". It is recommended to use the corresponding preparation methods in the 2020 Edition of Pharmacopoeia of the People's Republic of China. Modern clinical studies are centered around the clinical application of Xieqingwan, which is often modified and used in treating Tourette syndrome, herpes, febrile convulsion, sleepwalking, and insomnia. ConclusionThis paper conducts a thorough textual research of the key information of Xieqingwan, induces its historic evolution, and confirms its key information, so as to provide a reference for the future development of Xieqingwan.

ObjectiveTo understand the infection characteristics of multidrug-resistant organisms (MDROs) in hospitalized patients in a tertiary sentinel hospital in Shanghai, so as to provide an evidence for the development of targeted prevention and control measures. MethodsData of MDROs strains and corresponding medical records of some hospitalized patients in a hospital in Shanghai from 2021 to 2023 were collected, together with an analysis of the basic information, clinical treatment, underlying diseases and sources of sample collection. ResultsA total of 134 strains of MDROs isolated from hospitalized patients in this hospital were collected from 2021 to 2023 , including 63 strains of methicillin-resistant Staphylococcus aureus (MRSA), 57 strains of carbapenem-resistant Acinetobacter baumannii (CRAB), and 14 strains of carbapenem-resistant Klebsiella pneumoniae (CRKP). Of the 134 strains, 30 strains were found in 2021, 47 strains in 2022 and 57 strains in 2023. The male-to-female ratio of patients was 2.05∶1, with the highest percentage (70.90%) in the age group of 60‒<90 years. The primary diagnosis was mainly respiratory disease, with lung and respiratory tract as the cheif infection sites. There was no statistically significant difference in the distribution of strains between different genders and infection sites (P>0.05). However, the differences in the distribution of strains between different ages and primary diagnosis were statistically significant (P<0.05). Patients who were admitted to the intensive care unit (ICU), had urinary tract intubation, were not artery or vein intubated, were not on a ventilator, were not using immunosuppresants or hormones, and were not applying radiotherapy or chemotherapy were in the majority. There was no statistically significant difference in the distribution of strains for whether received radiotherapy or chemotherapy or not (P>0.05), while the differences in the distribution of strains with ICU admission history, urinary tract intubation, artery or vein intubation, ventilator use, and immunosuppresants or hormones use or not were statistically significant (all P<0.05). The type of specimen was mainly sputum, the hospitalized ward was mainly comprehensive ICU, the sampling time was mainly in the first quarter throughout the year, the number of underlying diseases was mainly between 1 to 2 kinds, the application of antibiotics ≥4 kinds, and those who didn’t receive any surgery recently accounted for the most. There were statistically significant differences in the distribution of strains between different specimen types, wards occupied and history of ICU stay (P<0.05), but no statistically significant difference in the distribution of strains between different sampling times, number of underlying diseases and types of antibiotics applied (P>0.05). ConclusionThe situation of prevention and control on MDROs in this hospital is still serious. Focus should be placed on high-risk factors’ and infection monitoring and preventive measures should be strengthened to reduce the incidence rate of MDROs infection.

Objective: To summarize the laboratory findings of a case of hemolytic disease of the fetus and newborn (HDFN) caused by Rh system anti-c antibodies and to review the literature, so as to explore the characteristics of anti-c HDFN. Methods: The ABO blood type, Rh blood type, direct antiglobulin test (DAT) results, and the presence of unexpected antibodies and their titers were determined by serological methods. The cases of anti-c HDFN in our laboratory in China and abroad were statistically analyzed, and the incidence of severe HDFN caused by anti-c, anti-D and anti-E was compared. Results: The blood type of the child was B (Rh CcDee) with a positive DAT. Anti-c antibody was detected in both serum and eluate, with a serum antibody titer of 4. The mother’s blood type was AB (Rh CCDee) with a negative DAT, and anti-c antibody was detected in the serum with a titer of 128. Among 20 cases of anti-c HDFN, 17 were DAT positive, and 9 (45%, 9/20) underwent blood transfusion or exchange transfusion. The incidence of severe HDFN was 47.60% (10/21) for anti-c, 47.60% (10/21) for anti-D and 31.30% (5/16) for anti-E. Conclusion: Maternal pregnancy and/or blood transfusion are the main reasons for the production of Rh alloantibodies such as anti-c. The prevention and management of anti-c should be similar to that of anti-D. Rh antigen-matched (five antigens of Rh blood group) transfusion is necessary for women of childbearing age to avoid antibody production, and Rh typing and antibody screening during prenatal examination is recommended to ensure early detection, intervention and treatment.

AIM: To investigate the correlation of degree of myopia in adolescents with axial length, corneal curvature and axial ratio.METHODS: Cross-sectional study. A total of 246 adolescents(492 eyes)aged 8-18 years consecutively enrolled for orthokeratology lens fitting at the Fifth Affiliated Hospital of Zhengzhou University between 2021 and 2023 were included based on random sampling method, with 447 eyes finally included due to the elimination of 45 eyes that did not meet the inclusion criteria. Biometric measurements under scotopic conditions assessed axial length(AL), corneal radius of curvature(CR), and AL/CR ratio. Cycloplegic refraction determined spherical equivalent(SE), classifying eyes into mild(216 eyes)or moderate(231 eyes)myopia groups. Furthermore, the correlation of degree of myopia with AL, CR and AL/CR was analyzed by multiple linear regression analysis.RESULTS: A statistically significant difference in myopia severity was observed between the 8-12-year-old and 13-18-year-old age groups(all P<0.001). There were statistically significant differences between mild and moderate groups in SE, AL and AL/CR(all P<0.001). Linear regression analysis revealed significant negative correlations of SE with AL and AL/CR(r=-0.531, -0.598, all P<0.001). The areas under the ROC curve(AUC)for predicting moderate myopia were 0.812(95% CI: 0.773-0.852)for AL/CR combined with gender and age, 0.800(95% CI: 0.759-0.841)for AL/CR alone, 0.726(95% CI: 0.680-0.773)for AL alone, and 0.548(95% CI: 0.494-0.601)for CR alone. The optimal AL/CR cut-off value for predicting moderate myopia was 3.189(sensitivity: 0.632, specificity: 0.852), suggesting its potential as a clinical threshold.CONCLUSION: In adolescents with mild-to-moderate myopia, AL/CR, AL, and SE showed significant negative correlations. The combination of AL/CR with gender and age demonstrated the highest diagnostic accuracy for SE. AL/CR shows independent predictive value for myopia degree in adolescents, irrespective of refractive status.

ObjectiveTo explore the effect of modified Lianpoyin formula (LPYJWF) in the treatment of Helicobacter pylori (Hp)-associated gastric mucosal damage based on mitochondrial autophagy and NLRP3 inflammasome signaling pathway. MethodsA total of 60 eight-week-old Balb/c male mice were assigned via the random number table method into control, model, high-dose LPYJWF (LPYJWF-H, 27.3 g·kg-1·d-1), medium-dose LPYJWF (LPYJWF-M, 13.65 g·kg-1·d-1), low-dose LPYJWF (LPYJWF-L, 6.83 g·kg-1·d-1), and quadruple therapy groups. Except the control group, other groups were modeled for Hp infection. Mice were administrated with LPYJWF at corresponding doses by gavage. Quadruple therapy group was given omeprazole (6.06 mg·kg-1·d-1) + amoxicillin (303 mg·kg-1·d-1) + clarithromycin (151.67 mg·kg-1·d-1) + colloidal pectin capsules (30.3 mg·kg-1·d-1) by gavage. The control group was given an equal volume of 0.9% NaCl for 14 days. Hematoxylin-eosin (HE) staining was used to observe the pathological changes of gastric mucosa, and Warthin-Starry (W-S) silver staining was used to detect Hp colonization. Transmission electron microscopy was employed to observe the mitochondrial ultrastructure of the gastric tissue, and immunofluorescence co-localization assay was adopted to detect the expression of mitochondrial transcription factor A (TFAM) and translocase of the outer mitochondrial membrane member 20 (TOMM20). The water-soluble tetrazolium salt method and thiobarbituric acid method were used to determine the levels of superoxide dismutase (SOD) and malondialdehyde (MDA), respectively, in the gastric tissue. Western blot was employed to measure the protein levels of PTEN-induced kinase 1 (PINK1), Parkin, p62, microtubule-associated protein 1 light chain 3 (LC3), NOD-like receptor protein 3 (NLRP3), apoptosis-associated speck-like protein containing a CARD (ASC), interleukin-1β (IL-1β), and interleukin-18 (IL-18). Real-time quantitative PCR was employed to assess the mRNA levels of PINK1, Parkin, p62, and LC3. ResultsCompared with the control group, the model group presented obvious gastric mucosal damage, colonization of a large number of Hp, severe mitochondrial damage, vacuolated structures due to excessive autophagy, reduced TOMM20 and TFAM co-expression in the gastric mucosal tissue, and reduced SOD and increased MDA (P<0.01). In addition, the gastric tissue in the model group showed up-regulated protein and mRNA levels of PINK1, Parkin, and LC3 and down-regulated protein and mRNA levels of p62 (P<0.01, as well as increased expression of inflammasome-associated proteins NLRP3, ASC, IL-1β, and IL-18 (P<0.01). Compared with the model group, the LPYJWF and quadruple therapy groups showed alleviated pathological damage of gastric mucosa, reduced Hp colonization, mitigated mitochondrial damage, and increased co-expression of TOMM20 and TFAM. The SOD level was elevated in the LPYJWF-L group (P<0.01), and the MDA levels became lowered in the LPYJWF and quadruple therapy groups (P<0.05, P<0.01). Furthermore, the LPYJWF and quadruple therapy groups showed down-regulated mRNA levels of PINK1, Parkin, and LC3 and protein levels of PINK1 and Parkin, and up-regulated mRNA level of p62 (P<0.01). The LPYJWF-M, LPYJWF-H, and quadruple therapy groups showcased down-regulated LC3 Ⅱ/LC3 Ⅰ level (P<0.05, P<0.01) and up-regulated protein level of p62 (P<0.01). The expression of inflammasome-associated proteins NLRP3, ASC, IL-1β, and IL-18 were reduced in the LPYJWF and quadruple therapy groups (P<0.05, P<0.01). ConclusionLPYJWF ameliorates gastric mucosal damage and exerts mucosa-protective effects in Hp-infected mice, which may be related to the inhibition of excessive mitochondrial autophagy, thereby inhibiting the activation of the NLRP3 inflammasome pathway.

Aim Based on the apoptotic pathway mediated by receptor interacting protein kinase(RIP)1-RIP3-mixed spectrum kinase domain like protein(MLKL), to explore the effects of naringenin on ovarian granulosa cell apoptosis in rats with polycystic ovary syndrome(PCOS). Methods SD rats were randomly assigned into normal control group, model group, naringenin group, RIP1 inhibitor(Nec-1)group, RIP1-RIP3-MLKL necrosis signal activator(Z-VAD-fmk)group, naringenin+Z-VAD-fmk group, 15 rats per group. ELISA method was performed to measure the levels of IL-1β and TNF-α in ovarian tissue. HE method was performed to observe the shape of the ovary. Granular cells were isolated from ovarian tissue, and flow cytometry was performed to measure apoptosis rate and necrosis rate. Immunohistochemistry was performed to measure the positive expression of p-RIP1 in ovarian tissue. Western blot was employed to detect the expression of RIP1-RIP3-MLKL pathway. Results RIP1 specific inhibitor Nec-1 and naringenin could block the phosphorylation and activation of RIP1, inhibit the RIP1-RIP3-MLKL signaling pathway, reduce the inflammation level in PCOS rats, and alleviate the necrosis and apoptosis of ovarian granulosa cells(P<0.05). Z-VAD-fmk could promote the activation of RIP1-RIP3-MLKL pathway, aggravate the apoptosis of ovarian granulosa cells, and partially weaken the anti-apoptosis effect of naringenin(P<0.05). Conclusions Naringenin may inhibit the apoptosis of ovarian granulosa cells in PCOS rats by blocking the activation of the necrotic apoptotic pathway mediated by RIP1-RIP3-MLKL.
