Objective To investigate the role of early detecting macrophage inflammatory protein‐1β(MIP‐1β) and proealcitonin (PCT ) level for the diagnosis of spontaneous bacterial peritonitis (SBP) in the decompensated stage of liver cirrhosis .Methods 384 cases of decompensated stage of liver cirrhosis complicating SBP collected in the Affiliated 3201 Hospital of Xi ′an Jiaotong Univer‐sity from May 2011 to February 2015 were included into the SBP group ,while other 377 cases of decompensated stage of liver cir‐rhosis complicating ascites were included into the control group .The serum and ascites samples were collected for detecting PCT by using electrochemical luminescence method and MIP‐1β by using the enzyme‐linked immunoassay .The significance of these two in‐dicators was compared between the serum detection and ascites detection .At the same time the clinical application value of these two indicators was analyzed by using the receiver operating characteristic curve .Results The serum and ascites PCT and MIP‐1βlevels in the SBP group were significantly higher than those in the control group ,the difference was statistically significant (P<0 .05) ;the serum PCT level in the SBP group had statistical difference between the patients with Gram‐negative bacteria infection and the patients with Gram positive bacteria infection (P< 0 .05) ;the ascites MIP‐1β level in the patients with Gram‐negative bacte‐ria infection of the SBP group was higher than that with Gram positive bacteria infection ,the difference was statistically significant (P< 0 .05) .Conclusion The serum and ascites PCT and MIP‐1β detection can help to the differentiation diagnosis of early decom ‐pensated stage of liver cirrhosis complicating SBP ;the serum PCT detection is superior to the MIP‐1β detection ,while ascites MIP‐1β detection is superior to the PCT detection .

Biochemical indexes and blood composition in early lactation health,ketosis and hypocalcemia dairy cows were analyzed to make sure the milk composition characteristics with related diseases,the correlation analysis between early lactating dairy milk composition and blood biochemical were also make in order to provide support for the cattle health assessment.According to theblood index,72 Holstein cows 7-21 d postpartum,were divided into group subclinical hypocalcemia,ketosis test group and control group,24 heads each group.The blood and milk of cows were collected and used to analyze the correlation between blood biochemical indexes and milk composition.The results showed that ketosis and hypocalcemia induced the level of milk protein and non fat milk solids decreased,while the content of citric acid in milk increased.The correlation equation between citric acid in milk and serum NEFA,BHBA and GLU was y=3.192x-0.802,(R2 =0.363),y=4.594x-0.793,(R2 =0.320),y=1.228x+0.775,(R2 =0.261),in which x was the content of citric acid in milk.The results showed that the content of citric acid in milk had positively related to blood NEFA,which could be used as an early marker for the diagnosis of negative energy balance.The levels of BUN and ALB in blood can be used to evaluate the levels of milk protein and urea.

The objective of this study was to determine the concentrations of calcium,phosphorus and magnesium in blood and compare the differences in seven areas of Heilongjiang province,and then estimate calcuim-phosphorus metabolism of beef cattle in seven beef cattle farms to provi detheoretical foundation for the prevention of calcium phosphorus metabolism diseases of beef cattle.Seven beef cattle farms of Daqing,Shuangyashan,Jiusan and Mudanjiang in Heilongjiang province were selected as the survey sites,which were recorded as group A (both grazing and stall-feeding in Shuangyashan),group B (stall-feeding mode in Shuangyashan),group C (stall-feeding mode in Daqing),group D (grazing mode in Jiusan),group E (both grazing and stall-feeding in Daqing),group F (both grazing and stall-feeding in Daqing) and group G (stall-feeding mode in Mudanjiang).Then the concentrations of Ca,Mg,P,free fatty acid (NEFA),glucose (Glc) and β-hydroxybutyric acid (BHBA) in the blood were compared to estimate the calcuim-phosphorus metabolic states.Results showed that the concentrations of calcium,magnesium and phosphorus in the plasma of 65 beef cattle in seven survey sites were within the normal range,and there was no significant difference in calcium concentration among seven sites.The P contents in group C and G were significantly higher those that in group A and B(P＜0.01),which in group C was significantly higher than those in group D,E and F (P＜0.01),which in group G was significantly higher than those in group D,E and F(P＜0.01).NEFA content in group B was significantly higher than that in group D (P＜0.05),and there was no difference among other groups.The concentration of Glc in group A was significantly higher than that in group E (P＜0.05),which in group B was significantly higher than those in group A and D,and was very significantly higher than those in group E,F and G (P＜0.01),which in group C was very significantly higher than those in group A,D,E,F and G (P＜0.01),which in group C was significantly higher than those in group A,D,E,F and G (P＜0.01),which in group D was significantly higher than that in group E (P＜0.05),and which in group F was significantly higher than that in group E (P＜0.05).The concentration of BHBA in group C,D and E were significantly higher than that in group A (P＜0.01),which in group C was significantly higher than that in group B (P＜0.05),which in group D and E was significantly higher than that in group B (P＜0.01),which in group C was significantly higher than that in group G (P＜0.01),which in group D was significantly higher than those in group F and G (P＜0.01),and in group E was highly significantly higher than that in group F and G (P＜0.01).Overall,there were not calcuim-phosphorus metabolic disorders within the seven beef cattle farms which were selected,but it is also necessary to strengthen feeding management and health care to prevent the occurrence of nutrition and metabolic diseases.

Objective To evaluate the safety and efficacy of irreversible electroporation (IRE) combined with neoadjuvant chemotherapy in patients with locally advanced pancreatic cancer. Methods We searched PubMed, Embase, Cochrane Library, Web of Science, China Biomedical Literature Database, CNKI, Wanfang, and VIP databases for articles dated from the establishment of each database to March 2022. Meta-analysis was performed using RevMan5.4 software. Results A total of 3970 patients with locally advanced pancreatic cancer were enrolled in eight studies, including one randomized controlled trial, four retrospective studies, and three prospective studies. The patients were divided into the combined therapy group with 344 patients and the chemotherapy-only group with 3626 patients. Meta-analysis showed that the overall survival of patients in the combined therapy group was significantly higher than that in the chemotherapy-only group (OR=4.52; 95%CI: 2.63-7.77; P < 0.00001). However, no significant difference existed in the disease control rate between the combined therapy group and the chemotherapy-only group (OR=0.58; 95%CI: 0.02-18.74; P=0.76). Moreover, no significant difference existed in the disease progression between the two groups (OR=0.49; 95%CI: 0.23-1.02; P=0.06). The combination of neoadjuvant chemotherapy and IRE had no significant effect on the incidence of adverse reactions of gastrointestinal reaction (OR=0.37; 95%CI: 0.10-1.34; P=0.13) and bone marrow suppression (OR=0.61; 95%CI: 0.26-1.40; P=0.24). Conclusion IRE combined with neoadjuvant chemotherapy can remarkably improve the prognosis of patients with locally advanced pancreatic cancer, and significantly prolong the overall survival.

AIM:To perform a multidimensional analysis of the clinical study characteristics of endo-metriosis based on the ClinicalTrials.gov,providing comprehensive and objective information for re-searchers,clinicians,and clinical pharmacists.METHODS:A thorough investigation was conduct-ed on clinical trials related to endometriosis,regis-tered on the ClinicalTrials.gov from its inception to October 20,2023.Relevant trial data were extract-ed and statistically analyzed using bibliometrics and comparative research methods.RESULTS:A to-tal of 667 endometriosis clinical studies were regis-tered globally,showing an annual increase.The United States(127 trials),France(70 trials),and Ita-ly(57 trials)had the highest number of registered trials.Interventional studies were predominant(416 trials,62.4%),followed by observational stud-ies(251 trials,37.6%).Within interventional stud-ies,drug therapy was the primary intervention(223 trials,53.6%).Despite endometriosis being a female condition,male subjects were also consid-ered,with 6 trials specifically requiring male partici-pants and 37 trials not restricting gender.Compa-nies/corporations were the main funding sources,while public and governmental organizations pro-vided relatively less funding.CONCLUSION:Clinical trial research on endometriosis is in a phase of growth,with drug therapy being the main treat-ment approach.However,there is a relative lack of investment and attention from public funds and governmental organizations.

Objective To explore the relationship between non-high density lipoprotein cholesterol(non-HDL-C)level and leptomeningeal collateral circulation in patients with acute middle cerebral artery occlusion.Methods A total of 85 patients with first-onset acute cerebral infarction with middle cerebral artery M1 segment occlusion were enrolled.According to the results of DSA,LMC circulation was assessed by American Society of Interventional and Therapeutic Neuroradiology/Society of Interventional Radiology Collateral Circulation Assess-ment System.All patients were assigned to better LMC circulation group(score 2～4,n = 30)and worse LMC circulation group(score 0～1,n = 55),and the levels of non-HDL-C were compared between the two groups.Results The levels of LDL-C and non-HDL-C in worse LMC circulation group were significantly higher than those of the better LMC circulation group(P = 0.026,P = 0.010).non-HDL-C was an independent risk factor for the worse LMC circulation(OR = 3.019,95%CI:1.053～8.658,P = 0.04).LMC circulatory score of patients was negatively correlated with the levels of non-HDL-C level(r =-0.228,P = 0.036).The AUC of non-HDL-C predicted for the worse LMC circulation was 0.638(95%CI:0.521～0.755,P = 0.036).Conclusions non-HDL-C in patients with acute cerebral infarction was significantly related to worse LMC circulation,and was a risk factor for worse LMC circulation.It is suggested that the higher expression of non-HDL-C could be used to predict worse LMC circulation as a serological indicator.

In recent years, monotherapy and combination therapy with immune checkpoint inhibitors (ICIs) have achieved good efficacy in a variety of malignancies from solid tumors to lymphomas and have become a standardized and systematic treatment modality for many cancers. However, there is still a lack of studies on the safety of ICIs in hepatitis B virus (HBV)-infected patients with malignancies, and early studies have reported HBV reactivation due to ICI antitumor therapy in clinical practice. With reference to related literature, this article reviews the recent clinical trials and application of ICIs in cancer patients with chronic viral infection and clarifies the efficacy and safety of ICIs in this special population, in order to provide a reference for clinical medication.

Objective:To analyze the risk factors of bronchopulmonary dysplasia(BPD)in very preterm infants(VPI), and to provide scientific basis for the prevention and treatment of BPD in VPI.Methods:A prospective multicenter study was designed to collect the clinical data of VPI in department of neonatology of 28 hospitals in 7 regions from September 2019 to December 2020.According to the continuous oxygen dependence at 28 days after birth, VPI were divided into non BPD group and BPD group, and the risk factors of BPD in VPI were analyzed.Results:A total of 2 514 cases of VPI including 1 364 cases without BPD and 1 150 cases with BPD were enrolled.The incidence of BPD was 45.7%.The smaller the gestational age and weight, the higher the incidence of BPD( P<0.001). Compared with non BPD group, the average birth age, weight and cesarean section rate in BPD group were lower, and the incidence of male infants, small for gestational age and 5-minute apgar score≤7 were higher( P<0.01). In BPD group, the incidences of neonatal respiratory distress syndrome(NRDS), hemodynamically significant patent ductus arteriosus, retinopathy of prematurity, feeding intolerance, extrauterine growth restriction, grade Ⅲ~Ⅳ intracranial hemorrhage, anemia, early-onset and late-onset sepsis, nosocomial infection, parenteral nutrition-associated cholestasis were higher( P<0.05), the use of pulmonary surfactant(PS), postnatal hormone exposure, anemia and blood transfusion were also higher, and the time of invasive and non-invasive mechanical ventilation, oxygen use and total hospital stay were longer( P<0.001). The time of starting enteral nutrition, cumulative fasting days, days of reaching total enteral nutrition, days of continuous parenteral nutrition, days of reaching 110 kcal/(kg·d) total calorie, days of reaching 110 kcal/(kg·d) oral calorie were longer and the breastfeeding rate was lower in BPD group than those in non BPD group( P<0.001). The cumulative doses of amino acid and fat emulsion during the first week of hospitalization were higher in BPD group( P<0.001). Multivariate Logistic regression analysis showed that NRDS, invasive mechanical ventilation, age of reaching total enteral nutrition, anemia and blood transfusion were the independent risk factors for BPD in VPI, and older gestational age was the protective factor for BPD. Conclusion:Strengthening perinatal management, avoiding premature delivery and severe NRDS, shortening the time of invasive mechanical ventilation, paying attention to enteral nutrition management, reaching whole intestinal feeding as soon as possible, and strictly mastering the indications of blood transfusion are very important to reduce the incidence of BPD in VPI.
