ObjectiveTo investigate and analyze an outbreak of rotavirus infectious diarrhea in a prison in Chongqing Municipality, to provide a basis for adult rotavirus surveillance and prevention, and to explore the public health problems in special settings. MethodsA retrospective survey was conducted to collect and analyze data on individual cases with diarrheal disease on-site. The clinical characteristics, as well as the temporal, spatial and geographical distribution patterns of the epidemic were described. Multi-pathogen detection tests were conducted both on diarrhea cases and environmental samples, with viral genotyping performed on positive samples. A case-control analysis was performed to identify the causes of the outbreak, and an SEIR model was adopted to predict the outbreak trend and evaluate the effectiveness of interventions. ResultsA total of 65 cases were found among the inmates, with an attack rate of 2.03%. The predominant clinical manifestations included diarrhea (89.23%), watery stool (73.85%), and dehydration (18.46%). The epidemic curve indicated a “human-to-human” transmission pattern, with an average incubation period of 5‒6 days. The attack rates among chefs in the main canteen (80.00%, 8/10) and caterers (28.33%, 17/60) were significantly higher than those of other inmates （P<0.05）. Multi-pathogen polymerase chain reaction (PCR) testing detected positive for group A rotavirus, with the viral genotyping identified as G9P [8] strain. Factors such as unprotected "bare-handed" food distribution among cases with diarrhea (OR=9.512, 95%CI: 4.261‒21.234) and close contact with diarrhea cases (OR=3.656, 95%CI: 1.719‒7.778) were the possible cause of the outbreak. The SEIR model (r₀=5, α=0.3, β₁=0.08, β₂=0.04) was constructed using prison inmates as susceptible population, aiming at fitting the initial transmission trend of the outbreak, and the epidemic rate declined rapidly after intervention measures were implemented (r_t≈0). ConclusionThis rare rotavirus infection diarrhea outbreak among adults in confined settings suggests that the construction of public health prevention and control systems in prison may be overlooked. Cross infection during meal processing and distribution in the canteens of such settings is likely to be the cause of the outbreak. Given the potential neglect of public heath system construction in special settings, it is imperative to enhance the surveillance and monitoring of rotavirus and other intestinal multi-pathogens among adults, as well as the construction of public health prevention and control systems in these special settings.

This paper summarized the clinical experience of Professor GE Linyi in treating ulcerative colitis （UC） by stages with the method of clearing. Professor GE believes that the core pathogenesis of UC is dampness and heat in the intestines， and by taking the method of clearing as the basis， he proposed four methods for treatment of UC including clearing and transforming， clearing and dispersing，clearing and moisterning， clearing and nourishing. The pathogenesis of UC in its active stage is dampness and heat in the intestines， congestion and stagnation of qi and blood， and accumulation of stasis toxins， for which the treatment method is to clear and transform， accompanied by clearing and dispersing method. In terms of the clearing and transforming method， Bai Tou Weng Decoction （白头翁汤） combined with Haungqin （Radix Scutellariae）， Machixian （Herba Portulacae） and Pugongying （Herba Taraxaci） is taken as the basic prescription to clear and transform dampness and heat， cool blood， resolve toxins and stop dysentery. For the clearing and dispersing method， medicinals to rectify qi such as Chaihu （Radix Bupleuri）， Cuxiangfu （Vingar Rhizoma Cyperi）， Muxiang （Radix Aucklandiae）， Zhiqiao （Fructus Aurantii）， and Binlang （Semen Arecae）， as well as those to regulate blood such as Danggui （Radix Angelicae Sinensis）， Cebaiye （Cacumen Platycladi） and Diyutan （Radix Sanguisorbae Carbonisatus） are recommended. The pathogenesis of the remission stage is healthy qi depletion and lingering pathogen of dampness and heat stasis toxin in the intestines， for which the method of clearing and nourishing， clearing and moistening can be used； the latter is mainly for people with yin fluids injury， and self-made Qingrun Yichang Decoction （清润益肠汤） is recommended， while the former is for those with spleen and stomach weakness， and self-made Qingyang Jianpi Decoction （清养健脾汤） can be used.

In the progression of end-stage liver disease,the incidence of sleep disorders in patients with liver cirrhosis is high.Currently,western medicine treatment has obvious liver and kidney damage and adverse reactions after discontinuation,which affects the therapeutic effect.Cirrhosis and sleep disorders can be separately attributed to the category of"abdominal mass"and"insomnia"in traditional Chinese medicine.The"abdominal mass"is caused by the disorder of liver and spleen qi movement,as well as the obstruction of phlegm-dampness and blood stasis.In the development of"abdominal mass",the liver failed in ensuring free movement of qi,the spleen failed in transportation and transformation,liver yin and liver blood became insufficiency and the imbalance of yin and yang in the zang-fu organs became imbalanced,and then the ethereal soul depart from the housing,which leads to"insomnia"as an outward manifestation.Professor ZHOU Xiao-Zhou focuses on the concept of qi and blood,and points out that the pathogenesis of sleep disorder in cirrhosis is characterized by liver stagnation and spleen deficiency.He proposed that the treatment principle is to regulate the liver and spleen simultaneously,as well as to nourish the heart and calm the mind.Professor ZHOU has developed Ganyinghua Anshen Formula for treating sleep disorders in cirrhosis,which is derived from the modification of Xiangsha Liujunzi Decoction,and is composed of 14 Chinese medicines of vinegar-prepared Cyperi Rhizoma,Amomi Fructus,Coicis Semen,Dioscoreae Rhizoma,bran-fried Atractylodis Macrocephalae Rhizoma,Galli Gigerii Endothelium Corneum,Gardeniae Fructus,Codonopsis Radix,Salviae Miltiorrhizae Radix et Rhizoma,Citri Reticulatae Pericarpium,Sclerotium Poriae Pararadicis,Longan Arillus,Albiziae Cortex,and Glycyrrhizae Radix et Rhizoma Praeparata cum Melle.The formula has achieved remarkable clinical effect.The clinical experience of Professor ZHOU Xiao-Zhou for treating sleep disorders in cirrhosis through regulating the liver and spleen simultaneously will provide a reference for its clinical treatment with traditional Chinese medicine.

Hip fracture in the elderly is characterized by high incidence, high disability rate, and high mortality and has been recognized as a public health issue threatening their health. Surgery is the preferred choice for the treatment of elderly patients with hip fracture. However, lower extremity deep venous thrombosis (DVT) has an extremely high incidence rate during the perioperative period, and may significantly increase the risk of patients′ death once it progresses to pulmonary embolism. In response to this issue, the clinical guidelines and expert consensuses all emphasize active application of comprehensive preventive measures, including basic prevention, physical prevention, and pharmacological prevention. In this prevention system, basic prevention is the basis of physical and pharmacological prevention. However,there is a lack of unified and definite recommendations for basic preventive measures in clinical practice. To this end, the Orthopedic Nursing Professional Committee of the Chinese Nursing Association and Nursing Department of the Orthopedic Branch of the China International Exchange and Promotive Association for Medical and Health Care organized relevant nursing experts to formulate Expert consensus on perioperative basic prevention for lower extremity deep venous thrombosis in elderly patients with hip fracture ( version 2024) . A total of 10 recommendations were proposed, aiming to standardize the basic preventive measures for lower extremity DVT in elderly patients with hip fractures during the perioperative period and promote their subsequent rehabilitation.

Objective Vascular dementia(VD)is a clinical syndrome caused by various cerebrovascular diseases,including ischemic,hemorrhagic,and acute and chronic hypoxic cerebrovascular diseases,leading to impaired brain function and affecting patients'cognitive ability,daily life,and work abilities.Vascular dementia is a preventable and reversible form of dementia,second only to Alzheimer's disease as the second common cause of dementia.At present,the relevant pathogenesis of vascular dementia is not clear,and there is no clear treatment method.However,its pathogenesis may be related to neuroinflammation,oxidative stress,neuronal damage and white matter lesions.Its main risk factors include genetic factors,hypercholesterolemia,diabetes,hypertension,etc.Neuroinflammatory response plays a major role in the process of secondary brain injury caused by cerebral ischemia,and inflammatory factors lead to an inflammatory cascade reaction that exacerbates damage to the nervous system.Inhibiting the inflammatory pathway and reducing the expression of inflammatory factors can improve the symptoms of vascular dementia patients and animal models,indicating that neuroinflammation may play an important role in the pathogenesis of vascular dementia.This article explores the effects of Buyang Huanwu Decoction on inflammatory factors from the perspective of summarizing relevant literature in recent years.It mainly reviews the pharmacological effects of Buyang Huanwu Decoction on treating vascular dementia,the relationship between inflammatory factor levels and vascular dementia,and the prevention and treatment of vascular dementia by regulating inflammatory factor levels.

AIM To explore the effects of praeruptorin A from Suhuang antitussive capsules on cough variant asthma(CVA).METHODS The rats were randomly divided into the normal group,the model group,the dexamethasone group(0.5 mg/kg),the Suhuang antitussive capsules group(7 g/kg)and the low,medium and high dose praeruptorin A groups(15,30 and 60 mg/kg).The rat model of CVA was established by intraperitoneal injection of sensitizer(1 mg/mL ovalbumin and 10 mg/mL aluminum hydroxide)and aerosol inhalation of 1%ovalbumin followed by the corresponding dosing of drugs by gavage initiated on the 14th day.Another 14 days later,the rats had their pathological pulmonary changes observed by HE,Masson and PAS stainings;their number of inflammatory cells in bronchoalveolar lavage fluid(BALF)detected by hematology analyzer;and their levels of IL-4,IL-5,IL-13 and MUC5AC in BALF detected by ELISA.The RAW264.7 cell inflammatory model induced by lipopolysaccharide(LPS)was treated with 4,8,16 μmol/L praeruptorin A or 0.25 mg/mL Suhuang antitussive capsules,respectively.And the cells had their NO level detected by Griess method,and their ROS expression observed using fluorescence microscopy.The detections of the pulmonary and cellular mRNA expressions of IL-6,IL-1β,COX-2,iNOS and PPAR-γ by RT-qPCR;and the protein expressions of p-P65,P65,p-IκBα,IκBα,NLRP3,caspase-1(p20)and IL-1β by Western blot were conducted in both the cells and the rats.RESULTS The in vivo result showed that praeruptorin A reduced the cough frequency(P＜0.01);prolonged the cough latency(P＜0.05,P＜0.01);reduced the number of eosinophils and neutrophils in BALF(P＜0.05,P＜0.01);decreased the levels of IL-4,IL-5,IL-13 and MUC5AC in BALF and the pulmonary mRNA expressions of IL-6,IL-1β,COX-2 and iNOS(P＜0.05,P＜0.01);and decreased the phosphorylation of P65 and IκBα protein and NLRP3,caspase-1(p20)and IL-1β protein expressions(P＜0.05,P＜0.01)as well.The in vitro result showed that praeruptorin A inhibited the release of LPS-induced NO and reduce the ROS level(P＜0.01);decreased the mRNA expressions of IL-1β,COX-2 and iNOS(P＜0.05,P＜0.01);increased PPAR-γ mRNA expression(P＜0.05),and decreased the phosphorylation of P65 and IκBα protein and the expression of NLRP3 protein(P＜0.05,P＜0.01).CONCLUSION Praeruptorin A,one of the main antitussive components of Suhuang antitussive capsules,may improve CVA because of its anti-inflammatory and antitussive role by inhibiting the activation of NF-κB signaling pathway and reducing the expression of NLRP3 inflammatory corpuscles.

Objective:To observe the effect of combining robot-assisted gait training (RAGT) with task-oriented training (TOT) on the walking ability of children with dyskinetic cerebral palsy (DCP).Methods:Sixty DCP children were randomly divided into a conventional intervention group, an RAGT group, and a combined intervention group, each of 20. All of the children received conventional rehabilitation therapy, while the RAGT and combined intervention groups were additionally provided with RAGT, and RAGT combined with TOT, respectively. Before the experiment and after 12 and 24 weeks of treatment, the subjects′ walking ability was evaluated using the 10-metre walk test (10MWT), and the D energy zone (standing position) and the E energy zone (walking, running and jumping) of the Gross Motor Function Measurement-88 (GMFM-88) instrument.Results:After 12 and 24 weeks of treatment, the average 10MWT speed and D and E energy zone scores of all three groups had improved significantly. After 24 weeks the combined group′s averages on all three measures were significantly better than those of the other two groups.Conclusion:RAGT combined with TOT and conventional rehabilitation training significantly improves the walking ability of DCP children.

BACKGROUND: Current replacement procedures for stenosis or occluded arteries using prosthetic grafts have serious limitations in clinical applications, particularly, endothelialization of the luminal surface is a long-standing unresolved problem.METHOD: We produced a cell-based hybrid vascular graft using a bioink engulfing adipose-derived mesenchymal stromal cells (ADSCs) and a 3D bioprinting process lining the ADSCs on the luminal surface of GORE-Tex grafts. The hybrid graft was implanted as an interposition conduit to replace a 3-cm-long segment of the infrarenal abdominal aorta in Rhesus monkeys. RESULTS: Complete endothelium layer and smooth muscle layer were fully developed within 21 days post-implantation, along with normalized collagen deposition and crosslinking in the regenerated vasculature in all monkeys. The regenerated blood vessels showed normal functionality for the longest observation of more than 1650 days. The same procedure was also conducted in miniature pigs for the interposition replacement of a 10-cm-long right iliac artery and showed the same long-term effective and safe outcome. CONCLUSION This cell-based vascular graft is ready to undergo clinical trials for human patients.

OBJECTIVE To systematically evaluate the safety of paroxetine in the treatment of pregnant patients with depression in the second and third trimesters of pregnancy， and provide reference for rational clinical use of it. METHODS Retrieved from Cochrane Library， PubMed， Embase， VIP， CNKI， Wanfang database and SinoMed database， by manual search， randomized controlled studies or observational studies were collected on depression patients who were given paroxetine vs. selective serotonin reuptake inhibitor （SSRI） in the second and third trimesters of pregnancy during the inception to Aug. 2022. Methodological qualities of the included studies were assessed by Cochrane Handbook 5.1.0 or Newcastle-Ottawa Scale （NOS）. Meta-analysis was performed with RevMan 5.4.1 software. RESULTS Finally， 9 observational studies were included， and all included studies were of high quality in NOS scale. Meta-analysis was performed on 8 cohort studies. Meta-analysis showed that the total incidence of adverse pregnancy outcomes of mothers and infants [RR＝0.99， 95%CI（0.89，1.10），P＝0.87]， total incidence of maternal adverse pregnancy outcomes [RR＝0.98， 95%CI （0.87，1.10）， P＝0.69] and premature birth [RR＝0.89， 95%CI （0.43， 1.83）， P＝0.75] in the second and third trimesters of pregnancy were lower than that with other SSRI， without statistical significance. The incidence of neonatal complications with paroxetine in the second and third trimesters of pregnancy was higher than that with other SSRI， but the difference was not statistically significant [RR＝1.02， 95%CI （0.82，1.29）， P＝0.84]. One study reported that the incidence of neonatal pulmonary hypertension in paroxetine group was higher than that in other SSRI group （0.4% vs. 0.3%）. CONCLUSIONS The safety of peroxetine in the second and third trimesters of pregnancy is comparable with that of other SSRI， but it is necessary to be alert to the occurrence of neonatal pulmonary hypertension.
