Erchentang is a classic formula widely used by medical practitioners throughout history. In this paper，ancient and modern literature of Erchentang were collected， and bibliometrics was employed to analyze its historic evolution，prescription meaning，herbs origin， processing method，preparation methods， and clinical application. A total of 84 pieces of data were collected， and 58 pieces of data involving 53 ancient medical Chinese books were screened， sorted， and processed. Combined with research of modern scholars，the research has found that the Erchentang originated from the Taiping Huimin Huiye Shijie Fang compiled by the Imperial Medical Bureau of the Song Dynasty. The basic information about the origin of the drugs is quite clear. Pinelliae rhizoma in the formula is the dried tuber of Pinellia ternata. Citri exocarpium rubrum is the dried mature peel of Citrus reticulata and its cultivated varieties， with the inner white membrane removed. Poria is the whitest dry sclerotia of Poria cocos； Glycyrrhizae radix et rhizoma is the dried root and rhizome of the Glycyrrhiza uralensis. The dosage is 5.70 g Pinelliae rhizome and Citri exocarpium rubrum， 3.43 g Poria， and 1.69 g Glycyrrhizae radix et rhizoma praeparata cum melle. During the decoction process， the above-mentioned herbs should be chopped， with 300 mL water， 7 g ginger in thick slices， and 2 g Mume fructus added， and it was then simmered together to 180 mL. After removing the medicinal residue， it can be taken warmly. Erchentang has the effect of drying dampness and resolving phlegm， regulating Qi and harmonizing the middle. It can be used in treating the syndrome of phlegm and dampness，as well as symptoms such as frequent cough，white phlegm，fullness in chest and diaphragm，nausea and vomiting，limb drowsiness，anorexia，dizziness，palpitations，white and greasy tongue coating， and slippery pulse. The above results provide reference for future research and development of Erchentang.

OBJECTIVE To investigate the clinical efficacy of integrating pharmacists into family health teams （FHTs） for long-term medication therapeutical management （MTM） in stroke patients， and empirically evaluate the service model. METHODS A pharmacist team， jointly established by clinical and community pharmacists from the Affiliated Suzhou Hospital of Nanjing Medical University （hereinafter referred to as “our hospital”）， developed a pharmacist-supported MTM model integrated into FHTs. Using a prospective randomized controlled design， 170 stroke patients discharged from our hospital （July 2022-December 2023） and enrolled in FHTs at Suzhou Runda Community Hospital were randomly divided into trial group （88 cases） and control group （82 cases） according to random number table. The control group received routine FHTs care （without pharmacist involvement in the team collaboration）， while the trial group xhz8405@126.com received 12-month MTM services supported by pharmacists via an information platform. These services specifically included innovative interventions such as personalized medication regimen optimization based on the MTM framework， dynamic medication adherence management， medication safety monitoring， a home medication assessment system， and distinctive service offerings. Outcomes of the 2 grousp were compared before and after intervention， involving medication adherence （adherence rate， adherence score）， compliance rates for stroke recurrence risk factors [blood pressure， low-density lipoprotein cholesterol （LDL-C）]， and incidence of adverse drug reactions （ADR）. RESULTS After 12 months， the trial group exhibited significantly higher medication adherence rates， improved adherence scores， higher compliance rates for blood pressure and LDL-C targets compared to the control group （P＜0.05）. The incidence of ADR in the trial group （4.55%） was significantly lower than that in the control group （8.11%）， though the difference was not statistically significant （P＞ 0.05）. CONCLUSIONS Pharmacist involvement in FHTs to deliver MTM services significantly enhances medication adherence and optimizes risk factor for stroke recurrence， offering practical evidence for advancing pharmaceutical care in chronic disease management under the family doctor system.

Sinisan is a classical prescription developed and applied by ancient medical experts and it is first recorded in the Treatise on Cold Damage written by ZHANG Zhongjing in the Eastern Han Dynasty. Later physicians have modified this prescription based on this original one. The bibliometrics methods were used to analyze the key information and research trend of Sinisan. According to the inclusion and exclusion criteria， 69 pieces of effective data were extracted， involving 67 ancient traditional Chinese medicine （TCM） books. The results showed that the name， composition， and decocting methods of Sinisan in later generations were inherited from the original record in the Treatise on Cold Damage. The original plants of medicinal materials used in Sinisan are basically clear. We recommend Bupleuri Radix as the dried root of Bupleurem scorzonerifolium， Paeoniae Radix Alba as the dried root of Paeonia lactiflora， Aurantii Fructus as the dried fruit of Citrus aurantium， Glycyrrhizae Radix et Rhizoma as the dry root and rhizome of Glycyrrhiza uralensis. Raw materials of Bupleuri Radix and Paeoniae Radix Alba， Aurantii Fructus stir-fried with bran， and stir-fried Glycyrrhizae Radix et Rhizoma should be used for preparation of Sinisan. According to measurement system in the Han Dynasty， a bag of Sinisan is composed of 1.25 g Bupleuri Radix， 1.25 g Paeoniae Radix Alba， 1.25 g Aurantii Fructus， and 1.25 g Glycyrrhizae Radix et Rhizoma. The materials should be grounded into coarse powder and taken with a proper amount of rice soup， 3 times a day. Sinisan has the effects of regulating qi movement and harmonizing the liver and spleen. It can be used for treating reversal cold in limbs and cold damage. In modern clinical practice， Sinisan can be used to treat chronic gastritis， irritable bowel syndrome， and dyspepsia. The above research results provide scientific reference for the future research and development of Sinisan.

Objective:To investigate the role of ubiquitin-specific protease 21 (USP21) in enterovirus group A type 71 (EV-A71) infection.Methods:Peripheral blood mononuclear cells (PBMC) were obtained from a cohort of 24 children infected with EV-A71 and 24 healthy children. Expression of USP21 was determined by real-time fluorescence quantitative PCR (qPCR). Additionally, the impact of USP21 overexpression or knockout on EV-A71 replication was evaluated using a combination of qPCR and western blot (WB) analysis. Furthermore, WB was employed to measure the levels of EV-A71 structural protein VP1, phosphorylated interferon regulatory factor 3 (IRF3) and other key molecules in the RIG-I-like receptor (RLR) signaling pathway. Co-immunoprecipitation (Co-IP) was utilized to investigate the effects of USP21 on the ubiquitin levels of EV-A71 nonstructural protein 2A protease (2A pro). Results:In comparison to healthy children, the expression of USP21 mRNA in PBMC of children infected with EV-A71 was notably elevated. The overexpression of USP21 significantly enhanced the cytopathic effects induced by EV-A71, upregulated levels of VP1 mRNA and protein, and facilitated EV-A71 replication, leading to a decrease in cell activity with increasing levels of USP21 transfection. Following the knockout of the USP21 gene, the VP1 mRNA levels were significantly declined in comparison to the control group. Furthermore, the overexpression of USP21 was found to have no impact on the transcriptional activity of EV-A71 2A pro. However, it was observed to enhance the expression of 2A pro protein, reduce the ubiquitination of 2A pro, suppress the protein levels of mitochondrial antiviral signaling protein (MAVS) and melanoma differentiation-associated gene 5 (MDA5), as well as decrease the phosphorylation of IRF3. Additionally, the induction of IFN-β mRNA by EV-A71 infection was downregulated. Conclusions:USP21 has been shown to enhance the replication of EV-A71 through the downregulation of 2A pro ubiquitination, suppression of MAVS and MDA5 protein expression, and inhibition of the interferon signaling pathway.

Objective:To explore and demonstrate the effect of general-specialty hierarchical management mode for chronic heart failure (CHF) in community.Methods:This was a single-blind, randomized, controlled study. A total of 530 CHF inpatients who attended Weifang Community Health Service Center (WCHSC) in Pudong New Area from February 2018 to September 2019 were consecutively enrolled. A random number table method was used to divide the patients into the management group ( n=265) and control group ( n=265). The demographic data and past medical history were collected 1 day before enrolment (baseline), and patients were assessed for New York Heart Association (NYHA) cardiac function classification and tested for blood N-terminal B-type natriuretic peptide proteins (NT-proBNP) levels, while Doppler echocardiography was performed to obtain the relevant indexes. The management group used a comprehensive management mode, co-delivered by both WCHSC (offering primary care) and RHSJUSM (offering specialty care) at Renji-Weifang CHF Studio in WCHSC , using the jointly developed CHF hierarchical CHF diagnosis and treatment criteria and referral procedure under the condition of sharing drugs and laboratory test results for CHF. The control group received routine heart failure care. Intergroup comparisons were made on baseline data obtained before follow-up and on NT-proBNP , left ventricular ejection fraction (LVEF), NYHA functional class , re-hospitalization rate and mortality rate at the end of the 6-month follow-up. Results:A total of 506 cases completed the follow-up. There were 253 patients in the management group, aged (68.26±9.41) years, 117 males (46.2%); 253 were in the control group, aged (66.98±9.63) years, 115 males (45.5%). There were no statistically significant differences in age, sex, marital status, education level, and comorbidities between the two groups (all P>0.05). At baseline, the differences in LVEF and NT-proBNP between the two groups were not statistically significant (all P>0.05), and at 6 months of intervention, LVEF, and NT-proBNP had significantly improved in both groups (all P<0.05) . Moreover, LVEF was higher in the management group than in the control group, and NT-proBNP was lower than in the control group (both P<0.01). At baseline, there were 166 cases (65.6%) in the control group with NYHA class Ⅲ/Ⅳ, and 145 cases (57.3%) in the comprehensive management group. There was no statistically significant difference between the two groups ( P>0.05). At 6 months of intervention, the percentage of NYHA class Ⅲ/Ⅳ patients in the comprehensive management group was lower than at baseline ( P<0.01),while that in the control group was higher than at baseline ( P<0.01), and the comprehensive management group was lower than that in the control group ( P<0.01). During the follow-up period, the rehospitalization rate for CHF in the management group was 13.83%(35/253), which was lower than that in the control group, which was 26.88%(68/253) ( P<0.001). Conclusion:The comprehensive management mode of CHF in the community through collaboration between general and specialized departments can significantly improve the management effect, suggesting that this mode is effective and can be promoted.

Objective To retrospectively analyze the clinical risk factors and prognosis of perioperative myocardial injury(MINS)in non-cardiac surgery patients admitted to the intensive care unit(ICU).Methods A total of 478 postoperative patients admitted to the Department of Intensive Medicine,Minhang Hospital,Fudan University from Jan 2020 to Dec 2023 were selected.They were divided into MINS group(n=302)and normal group(n=176)based on whether myocardial injury occurred within 7 days after surgery.The differences in clinical characteristics between the two groups were compared,and risk factors for perioperative myocardial injury were identified.Risk factors for mortality in the MINS group were analyzed with 30-day mortality as the clinical endpoint.Results The prevalence of acute physiology and chronic health evaluation Ⅱ(Apache Ⅱ)score,coronary artery disease,and chronic kidney disease were all higher in the MINS group than those in the normal group,with statistically significant differences(P<0.05).The proportion of emergency surgeries,co-infection,and perioperative hypotension were significantly different between the MINS group and the normal group(P<0.05).Multivariate logistic regression analysis revealed that chronic kidney disease,emergency surgery,co-infection,and intraoperative and postoperative hypotension were risk factors for MINS occurrence.Prognostic analysis indicated that perioperative hypotension was a risk factor for 30-day mortality in MINS patients.Conclusion MINS is closely associated with patients'underlying conditions,timing of surgery,and perioperative hypotension status,and especially perioperative hypotension affects the final outcomes.

Objective:To investigate the clinical and genetic variation characteristics of a child with autosomal dominant lateral temporal lobe epilepsy caused by de novo variation of the MICAL1 gene. Methods:Clinical data of the patient with autosomal dominant lateral temporal lobe epilepsy caused by MICAL1 gene variation diagnosed in Children′s Hospital of Soochow University in August 2019 were collected. The whole exome sequencing was performed on the core members of the family, and the characteristics of gene variations were analyzed. Results:The proband, a 10 years and 5 months old boy, was admitted to the hospital because of "intermittent convulsions for 7 years". The clinical manifestations included focal or generalized tonic-clonic seizures and hearing aura, with normal language and intellectual development. No abnormalities were found in the T 1 and fluid attenuated inversion recovery sequences of the cranial 3.0 T magnetic resonance imaging and 3D thin-slice magnetic resonance imaging.Long-range video electroencephalogram showed the distribution of spinous and slow spinous waves in the left frontal and temporal areas. The results of whole exome gene sequencing in the core family members showed heterozygous de novo missense variation in the MICAL1 gene of the proband (NM_022765): c.763G>T(exon6)(p.Val255Leu) that had not been reported. According to American College of Medical Genetics and Genomics and Association for Molecular Pathology guidelines (2015), the mutation was considered potentially pathogenic. The application of antiepileptic drugs was effective in controlling epileptic seizures. Conclusions:Auditory symptoms are main clinical manifestations for the child with autosomal dominant lateral temporal lobe epilepsy. Antiepileptic drugs can effectively control epileptic seizures of the child, and the MICAL1 gene c.763G>T (p.Val255Leu) mutation is the genetic cause of the proband.

Objective:To investigate and summarize the imaging and pathological features of non-acute occlusion following flow diverter (FD) implantation in animal models.Methods:Four experimental pigs (experimental group) that experienced non-acute occlusion (occlusion time exceeding 24 hours) within the FD stent implanted in the common carotid artery, and 19 pigs (control group) that did not experience stent occlusion during the same period were involved. Using an interventional approach under digital subtraction angiography (DSA), the 4 occluded FD lumens were mechanically opened. Optical coherence tomography (OCT), intravascular ultrasound (IVUS) and histopathological examinations were performed to evaluate the intraluminal composition and characteristics of the occlusive tissues. These findings were compared with non-occluded FD stents to summarize the imaging and pathological changes within the occluded FD lumen.Results:The occlusion times of the FD stents in the 4 experimental pigs were 16 weeks, 20 weeks, 20 weeks, and 24 weeks postoperatively. All occluded stents were successfully recanalized under DSA, with a technical success rate of 4/4. Among the 19 non-occluded FD stents, OCT and IVUS revealed uniform (16 stents) or non-uniform (3 stents) neointimal coverage of the stent struts, presenting as homogeneous high/slightly high signal intensity or medium echogenicity. Histopathological examination indicated that the neointima was primarily composed of smooth muscle cells and a small amount of fibrous connective tissues. In contrast, the 4 occluded FD stents demonstrated excessive neointimal proliferation and plaque formation, leading to luminal loss, as shown by OCT and IVUS. The occlusion tissues predominantly presented as homogeneous high signal intensity with weak attenuation (fibrous plaques) on OCT, with some regions showing blurred low signal intensity and strong attenuation (lipid plaques). IVUS presented homogeneous echogenicity (fibrous plaques) and hypoechogenic zones (lipid plaques). Histopathological examination showed that the occlusion tissues mainly consisted of smooth muscle cells, fibrous connective tissues, and lipids, accompanied by numerous foam cells and a minor presence of inflammatory cells.Conclusions:Histopathological examinations confirm that non-acute occlusion of FD is mainly caused by excessive hyperplasia of intima along with the formation of fibrous plaques and lipid plaques. OCT and IVUS have typical finding in imaging that can assist in determining the cause of stent occlusion as well as the lesion's nature, thereby providing crucial guidance for subsequent clinical treatment and drug selection.

Objective:To evaluate the clinical value of multi-disciplinary treatment (MDT) combined with enhanced recovery after surgery (ERAS) for the elderly patients with osteoporotic ankle fracture.Methods:A retrospective analysis was conducted to analyze the 88 elderly patients with osteoporotic ankle fracture who had been treated with MDT combined with ERAS or non-MDT at Department of Foot and Ankle Surgery, Shanghai Sixth People's Hospital from January 2021 to January 2024. According to whether MDT was adopted or not, this cohort was assigned into 2 groups using the propensity score matching method: a MDT group and a non-MDT group with a matching ratio of 1∶1 (44 cases per group). The 2 groups were compared in terms of choice of intraoperative fixation, hospital stay, time for return to work/daily life, patient satisfaction questionnaire (PSQ-18) during hospitalization, ankle range of motion at 1 and 3 months after surgery, ankle-hindfoot score of American Orthopaedic Foot and Ankle Society (AOFAS), visual analogue scale (VAS) for pain, gait, and incidence of complications.Results:There were no significant differences in the preoperative general data between the 2 groups, indicating comparability ( P<0.05). The choice of intraoperative fixation, PSQ-18 [(78.4±8.5) points], AOFAS ankle-hindfoot score at 3 months after operation [(75.4±8.2) points], and gait in the MDT group were significantly better than those in the non-MDT group [(74.2±9.6) points and (70.9±9.4) points] ( P<0.05). There was no significant difference in the hospital stay or time for return to work/daily life between the 2 groups ( P>0.05). There was no statistically significant difference either in ankle dorsiflexion or plantarflexion, VAS for pain, or incidence of complications between the 2 groups at 1 or 3 months after surgery, as well as in AOFAS ankle-hindfoot score or gait at 1 month after surgery ( P>0.05). Conclusion:MDT combined with ERAS can effectively increase the therapeutic efficacy for the elderly patients with osteoporotic ankle fracture, improve their function of affected limbs, and enhance their patient satisfaction.
