ObjectiveTo observe the clinical efficacy and safety of traditional Chinese medicine （TCM） triple therapy in the treatment of spontaneous bacterial peritonitis （SBP） with damp-heat stagnation and toxin-blood stasis syndrome in liver cirrhosis patients， and to explore its potential mechanisms of action. MethodsEighty-six patients were randomly divided into the experimental group and the control group， with 43 patients in each group. Both groups received standard western medicine treatment， while the experimental group additionally received TCM triple therapy， including oral Qingre Liangxue Jiedu Decoction （清热凉血解毒汤）， retention enema with Dachengi Decoction （大承气汤）， and abdominal application of Qingre Zhitong Lishui Fomulation （清热止痛利水方） with lotus leaf. Both groups were treated for 2 weeks. Before and after treatment， various indicators were measured， such as TCM syndrome scores， ascites volume measured by abdominal ultrasound， liver function indicators including total bilirubin （TBIL）， alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， and albumin （ALB）， infection markers， including neutrophil percentage （NEUT%）， C-reactive protein （CRP）， and procalcitonin （PCT）， inflammatory factors， such as tumor necrosis factor-alpha （TNF-ɑ）， interleukin-6 （IL-6）， and interleukin-10 （IL-10）， intestinal mucosal barrier function markers， including endotoxin （ET）， diamine oxidase （DAO）， D-lactic acid （D-Lac）， occludin， and zonula occludens-1 （ZO-1）， and peritoneal polymorphonuclear （PMN） cell counts at 72 hours post-treatment. ResultsA total of 82 patients were included in the final analysis， with 41 patients in each group. The total effective rate for TCM syndrome in the experimental group was 92.68% （38/41）， which was significantly higher than the 80.49% （33/41） in the control group （P＜0.05）. Compared with pre-treatment values， both groups showed significant reductions in TCM syndrome scores， ascites volume， TBIL， ALT， AST， NEUT%， CRP， PCT， TNF-α， IL-6， ET， DAO， D-Lac， Occludin， and ZO-1， with an increase in IL-10 levels and a decrease in PMN count in ascites 72 hours post-treatment （P＜0.05）. Furthermore， the experimental group outperformed the control group in all the above indicators after treatment （P＜0.05）. The disappearance time of fever and abdominal pain was shorter in the experimental group than in the control group （P＜0.01）. There were no significant changes in routine urine and stool tests， renal function， electrolytes， or electrocardiogram in either group compared with pre-treatment values. ConclusionTCM triple therapy in addition to western medicine routine treatment could significantly improves clinical symptoms in patients with liver cirrhosis and SBP with damp-heat stagnation and toxin-blood stasis syndrome， alleviates liver inflammation， improves liver function， accelerates the resolution of ascites， and increases clinical efficacy. The potential mechanism may be related to the regulation of the inflammatory response and the promotion of intestinal mucosal barrier repair.

Objective To explore the drug selection, usage, dosage and effect of clinical pharmacists in the treatment of secondary Candida bloodstream infection in patients with digestive tract perforation, and provide reference for rational clinical use of such anti-infection therapy. Methods During the treatment of Candida infection, anti-infection specialist clinical pharmacists suggested replacing fluconazole for anti-infection treatment, and adjusted the usage and dosage of caspofungin to ensure the application of full treatment course. Results The patient’s Candida bloodstream infection was effectively controlled. Conclusion Echininocandins such as caspofungin are the first choice for Candida infection. The maintenance dose should be reduced to 35 mg qd in patient with moderate liver function injury, and the anti-infection treatment should be done at least 14 days after the blood culture being negative. Clinical pharmacists participate in clinical pharmaceutical care practices such as clinical ward rounds, and actively assist doctors to develop individualized anti-infection programs, which could improve the level of clinical drug use and the clinical outcome of diseases.

Objective To explore the effects of electromagnetic field(EMF)on thechange of Ca2+ in osteolbast from the qualitative and quantitative perspectives,and try to identify the role of Ca2+in EMF regulation on osteoblast proliferation and differentiation.Methods A platform was established for generating sine EMF with a frequency of 38.7 Hz and a strength of 1.5 mT.The MC3T3-E1 osteoblasts were randomly divided into control group and experimental group(EMF intervention for 8 h per day).CCK8 was used to detect osteoblast proliferation,ALP staining to detect osteoblast differentiation,and Ca2+fluorescence probes and flow cytometer to detect the Ca2+concentration in osteoblasts.Results CCK8 result showed that EMF intervention for 48,72,96 and 120 h could significantly promote osteoblast proliferation.After 14 days of EMF intervention,the positive expression of ALP was significantly higher in EMF group than in control group.Ca2+fluorescent staining and flow cytometry results revealed that EMF intervention could increase the Ca2+in osteoblasts.Conclusion The EMF-induced upregulation of Ca2+ signal in osteoblasts may be closely related to the promotions of osteoblast proliferation and differentiation by EMF,but which Ca2+-related biosignaling pathways are involved in the EMF promoting osteoblast proliferation and differentiation remains to be further investigated.

Palliative and hospice care is an emerging medical care model for the development of modern medicine,and its emergence is not only a sign of social demand and the development of human civilization,but also an important manifestation of the change in the modern medical model.Hospice care is the final stage of palliative care,which is of great significance for the end-of-life treatment of incurable diseases.Palliative and hospice care has become an independent discipline in many countries,and its development has been rapid.However,the develop-ment of hospice and palliative care in China is not satisfactory,and the lack of money and human resources are the main reasons limiting its development.Many scholars have carried out a lot of useful practices in this regard.How to explore a road of hospice and palliative care development suitable for China′s national conditions is an urgent problem to be solved.By reviewing domestic and foreign literature,this paper summarizes the development mode and payment method of palliative and hospice care abroad,identifies the challenges encountered in the practice of hospice care in China,and draws on the development experience of palliative and hospice care in foreign countries.We aimed to identify pain points and difficulties faced in developing palliative and hospice care in China,so as to better serve patients at the end of life,gradually promote the concept of palliative and hospice care,and contribute to the sustainable development of palliative and hospice care in China.

Since the proposal of the concept of the gut-liver axis,a large number of studies have focused on exploring the connection between gut microbiota and liver disease;however,the idea of using pyroptosis as a hub to explore the intrinsic mechanism of gut-liver crosstalk is still in its infancy.This article mainly describes the process by which gut microbiota dysbiosis affects the integrity of mucosal barrier and bile acid metabolism,induces pyroptosis,and thereby affects the development and progression of liver diseases,and it also concludes that gut microbiota dysbiosis affects liver diseases by inducing NLRP3/AIM2/Caspase-1-dependent,Caspase-4/11/GSDMD-dependent,and Caspase-3/GSDME-dependent pyroptosis.In summary,this study aims to provide new ideas and targets for the future diagnosis and treatment of liver diseases by establishing the connection between pyroptosis and intestinal-liver immune crosstalk.

Objective To explore the clinical efficacy of single unicompartmental knee arthroplasty(UKA)and total knee arthroplasty(TKA)for the treatment of knee osteoarthritis.Methods A total of 21 patients who underwent TKA and 15 who underwent UKA were randomly recruited.Biomechanical tests were performed before surgery and at 6th and 12th month after surgery.A Vicon infrared motion capture system and Kistler three-dimensional force plate were used to simultaneously acquire the kinematic and kinetic data of the patients during stair walking.Results During stair ascent,the peak knee flexion moment in the TKA group was significantly lower than that in the UKA group;the time to peak knee flexion/adduction moment,knee flexion moment impulse,and load rate of the peak knee adduction moment in the UKA group were significantly lower than those in the UKA group.During stair descent,the peak knee extension power in the UKA group was significantly lower before surgery and at 6th month after surgery;the load rate of the peak vertical ground reaction force was significantly higher before surgery and the peak knee extension moment was significantly greater at 6th month after surgery;at 12th month after surgery,there was no significant difference in the biomechanical characteristics during stair ascent and descent.Conclusions The TKA and UKA groups showed similar knee joint function after surgery;however,compared with the UKA group,the TKA group may adopt a different lower extremity biomechanical pattern.The UKA group showed better quadriceps control after surgery and improved postural control during stair descent,whereas the TKA group adopted a conservative stair gait strategy to reduce the knee load.Compared with the peak moment,the time to peak moment and load rate of the peak moment were more sensitive indicators for determining the difference in the knee load.

In order to achieve the purpose of rapid detection of duck astrovirus type 1(DAstV-1),specific primers were designed based on the conservative region of ORF1a which belonged to DAstV-1(WF1202 strain).A real-time fluorescent quantitative PCR(qPCR)detective method for DAstV-1 was established.Clinical samples were detected by the qPCR method and the positive samples were used for virus isolation and identification.Results showed that the detection limit of the established method was 4.64×103 copies/μL,which was 10 times higher than the normal RT-PCR method.In addition,no cross-reactions were found with other common infectious disease pathogens in poultry,indicating that the qPCR method had good specificity.What's more,the coef-ficient of variations(Cv)in intra-and inter-assays were 0.85％-2.85％and 0.21％-2.94％,re-spectively,both less than 3％,indicating that the qPCR method had a good repeatability.Using this method,35 tissue samples from different duck farms in 10 provinces from 2020 to 2022 were detected for DAstV-1.Results showed that the positive rate was 25.71％(9/35),and the coinci-dence rate was 94.29％when compared with the normal RT-PCR method.A positive sample ran-domly taken for the virus isolation through duck embryo passage,and the allantoic fluid was col-lected and then was verified by the qPCR method and inoculated with 1-day-old healthy ducklings for the animal regression experiment.The infected ducklings suffered from transient disease but did not die.The liver tissues were all positive with DAstV-1 when detected by qPCR.Meanwhile,autopsy showed that there were slight changes in the livers,and the histopathological observation showed that the liver cells were steatosis.These findings indicated that the isolated DAstV-1 strain had weak pathogenicity and might be a low virulent strain.To sum up,the qPCR detection method of DAstV-1 was successfully established in this work,and could provide technical support for clini-cal diagnosis,isolation and identification,and molecular epidemiology monitoring of DAstV-1.

In order to understand the prevalence of Akabane disease(AKAD)in Guizhou Province and the molecular characteristics of the isolates,the whole-genome sequence of a strain of Akabane virus(AKAV)from a bovine AKAD-positive sample was determined and analyzed.The genotype and genetic variation of the strain were also explored.Based on the conserved S sequence,a fluores-cence quantitative PCR(qPCR)detection method was established and applied for the investigation of AKAV infection status in four large-scale beef cattle farms of Guizhou.Results showed that the S,M and L fragments of the bovine strain were highly homologous to the Tianjin strain(TJ2016/China/2016)and the Australian strain(JaLAB39/Australia/1959),where they were in the same evolutionary branch and belonged to genotype Ⅱ.Sensitivity assay found that the lowest detection limit was 2.5 X 101 copies/μL.Specificity assay showed the established method detected only AKAV with no amplification on bovine bluetongue virus(BLUV),Pasteurella multocida(PM),bovine infectious rhinotracheitis virus(IBRV)and bovine Mycoplasma bovis.The variation coefficients of inter-and intra batches in the repeatability test were both lower than 2.26％.These findings illus-trated that the established qPCR method had high sensitivity,good specificity and repeatability.A total of 298 serum samples from 4 large-scale beef cattle farms in Qianxi City and Huangping County of Guizhou Province were collected and tested for AKAV by the method.Out of 298 sam-ples,25 positive samples(25/298)were detected as positive with a positive rate of 8.39％.In sum-mary,this work provided the reference data for a deep understanding of the molecular prevalence of AKAV in Guizhou Province and laid foundation for the prevention and control of AKAD.

Objective:To study the clinical characteristics and risk factors for hypertriglyceridemia-induced severe acute pancreatitis (HTG-SAP) complicated by acute kidney injury.Methods:The clinical data of HTG-SAP patients admitted to the Department of Critical Care Medicine of the Second Affiliated Hospital of Anhui Medical University from January 2014 to July 2022 were retrospectively collected, and divided into an AKI group and a non-AKI group according to whether AKI occurred. The general condition, laboratory data and clinical characteristics of the two groups were compared. Factors with statistically significant differences were screened for logistic regression analysis and a predictive model was constructed. We plotted the receiver operating characteristic curve and used the area under the curve (AUC) to evaluate the predictive ability of each predictor for HTG-SAP complicated with AKI.Results:A total of 91 patients were included, including 37 (40.7%) with AKI and 54 (59.3%) without AKI. The proportions of extrapancreatic infection, sepsis and multiple organ dysfunction syndrome, requiring mechanical ventilation, continuous renal replacement therapy (CRRT), retroperitoneal puncture, and surgical intervention were higher in the AKI group than in the non-AKI group (all P<0.05). The length of ICU stay, total length of hospitalization, and mortality rate in the AKI group were higher than those in the non-AKI group (all P<0.05). Multivariate logistic regression analysis showed that acute physiology and chronic health status scoreⅡ (APACHEⅡ) ( OR=2.069, 95% CI: 1.286-3.417, P=0.003), abdominal pressure ( OR=1.469, 95% CI: 1.108-1.958, P=0.007), and lactic acid ( OR=3.156, 95% CI: 1.013-9.831, P=0.047) were independent risk factors for AKI in HTG-SAP patients. The AUCs of the APACHEⅡ score, abdominal pressure, lactic acid level and combined prediction model were 0.951, 0.918, 0.837 and 0.986, respectively. Conclusions:Patients with HTG-SAP complicated with AKI were more likely to have complications related to extrapancreatic infection, sepsis and multiple organ dysfunction, and the proportion of mechanical ventilation, CRRT, retroperitoneal puncture and surgical intervention required during hospitalization was greater, the lengths of ICU stay and total hospital stay were longer, and the mortality rate was higher. APACHEⅡ score, abdominal pressure and lactic acid were independent risk factors for HTG-SAP concurrent AKI, and the prediction model established based on these three factors had higher value in predicting HGT-SAP concurrent AKI

OBJECTIVE To provide reference for rational use of cyclin-dependent kinase 4/6 （CDK4/6） inhibitors. METHODS Retrieved from Web of Science， PubMed， SpringerLink， CNKI， Wanfang Data and VIP database， and so on， the literature about lung toxicity related to CDK4/6 inhibitors were collected and analyzed statistically with Excel 2013 software. RESULTS A total of 12 literature which met the inclusion and exclusion criteria were included； 13 patients were involved， among which 3 cases were from the United States， 3 from Japan， 2 from India， and 1 from Israel， Spain， France， Australia and Saudi Arabia respectively； all patients were female， aged between 43-89 years， of whom 8 were treated with palbocicilib， 3 with abemacilib， and 2 with ribociclib. The lung toxicity of patients after medication occurred from 1 week to 15 months； the majority of patients were hospitalized with the symptom such as difficulty breathing， chest tightness， shortness of breath， dry cough， etc. The lung toxicity mainly manifested as interstitial lung disease， eosinophilic pneumonia， mediastinal and pulmonary granulomatous reaction， drug-induced pneumonia， diffuse alveolar damage， organizing pneumonia and so on. The shortest treatment duration was 3 weeks， and the longest was 6 months. The treatment measures included drug withdrawal， intravenous use of antibiotics， intravenous use of systemic steroids， oxygen inhalation， and so on； after treatment， 8 patients improved or recovered， and 5 patients died due to deterioration. One patient developed lung toxicity again after reuse of such drugs and must stop drugs permanently. CONCLUSIONS Lung toxicity related to CDK4/6 inhibitors possibly cause mortality. It is necessary to make early judgment， stop the drug in time， and give patients systemic steroids， oxygen inhalation and other treatment measures as soon as possible.
