Objective To evaluate the efficacy of intraoperative negative pressure drainage in preventing seroma after laparoscopic totally extraperitoneal (TEP) hernia repair. Methods A total of 200 patients undergoing TEP repair in our hospital from January 2022 to December 2022 were divided into two groups (n=100 each). The study group received intraoperative negative pressure drainage, while the control group did not. Therapeutic outcomes and postoperative complications were compared between the two groups. Results There were no significant differences between the two groups in operative time, pain scores, incidence of wound infection, or recurrence rates (P > 0.05). However, the study group showed a significantly lower incidence of postoperative seroma compared to the control group (P < 0.05). For direct hernias, the operative time in the study group was significantly shorter than that in the control group (P < 0.05). No mesh infections were observed in either group. Conclusions Prophylactic negative pressure drainage significantly reduces seroma formation without increasing other postoperative complications and is easy to be performed. The application of negative pressure drainage is recommended in cases of scrotal and direct hernias.

Polysaccharides, a class of complex macromolecules, are distinguished by their diverse biological functions and essential role in functional foods. The distinctive biological activities of polysaccharides from medicine and food homology materials (MFPs), including immunomodulation, carbohydrate metabolism regulation, and lipid metabolism regulation properties, have attracted considerable scientific attention. The relationship between polysaccharides and gut microbiota is fundamental to human health, as polysaccharides demonstrate efficacy in ameliorating various conditions-from inflammatory bowel disease (IBD) to obesity and diabetes-through their influence on intestinal flora composition and diversity. Although polysaccharide research and applications show promise, significant challenges persist, particularly regarding extraction and purification methodologies, and the complete understanding of their biological mechanisms. Future investigations should prioritize understanding the correlation between polysaccharide structure and function, advancing large-scale production and application technologies, and establishing productive interdisciplinary collaborations. MFPs demonstrate significant potential for advancing sustainable development and human health, building upon current research findings. This paper presents a comprehensive review of global developments in the extraction, purification, structural characterization, biological activities, and applications of MFPs, emphasizing opportunities for scientific and technological innovations in specialized dietary food development.

Objective:To compare the expression difference of Toll like receptor (TLR) and inflammatory factors between pancreatic cancer and normal pancreatic epithelial cells, and explore the correlation between TLR and inflammatory microenvironment.Methods:Normal pancreatic duct epithelium cells (HPNE) and pancreatic cancer cells (Panc-1 and Mia-PACA-2) were cultured and proteins were obtained. The expression of TLR family protein, interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) and myeloid differentiation factor 88 (MyD88) were examined by western blot in HPNE, Panc-1 and Mia-PACA-2. The correlations between TLR and inflammation cytokines of pancreatic cancer were analyzed by Pearson correlation analysis.Results:Compared with HPNE, the TLR2, TLR3, TLR4, TLR7, TLR8 and TLR9 were highly expressed in Panc-1 and Mia-PACA-2 (all P<0.05). Compared with Panc-1, the expression of TLR2 and TLR4 in Mia-PACA-2 were increased obviously, while the TLR9 expression was mildly decreased (all P<0.05). The expression of IL-6 in HPNE was found less than that in Panc-1 (0.52±0.03 vs. 0.76±0.04) and Mia-PACA-2 (0.52±0.03 vs. 1.12±0.09) with statistical differences ( P<0.05). Similarly, the expression of TNF-α was found significantly less than that of Panc-1 cells (0.63±0.04 vs. 0.87±0.06) and Mia-PACA-2 cells (0.63±0.04 vs. 0.95±0.10) with statistical differences (all P<0.05). The expression of IL-6 was found positively correlated with expressions of TLR2 ( r=0.964), TLR4 ( r=0.968), TLR7 ( r=0.844), TLR8 ( r=0.668) (all P<0.05), and the expression of TNF-α was found positively correlated with expressions of TLR2 ( r=0.805), TLR4 ( r=0.893), TLR7 ( r=0.847), TLR8 ( r=0.780) (all P<0.05). In contrast with HPNE, the expression of MyD88 was found highly expressed in Panc-1 (0.91±0.10 vs. 0.33±0.03) and Mia-PACA-2 (1.14±0.10 vs. 0.33±0.03) (all P<0.001). Compared with Panc-1, the expression of MyD88 in Mia-PACA-2 was obviously increased (1.14±0.10 vs. 0.91±0.10) with statistical difference ( P=0.048). Conclusion:The TLR family may play a critical role in development of pancreatic cancer by regulating the immune microenvironment, and its mechanism may be through upregulating MyD88 which functions as key signal transduction.

PURPOSE: Details of patients hospitalized for asthma exacerbation in mainland China are lacking. To improve disease control and reduce economic burden, a large sample survey among this patient population is indispensable. This study aimed to investigate the clinical characteristics and outcomes of such patients.METHODS: A retrospective study was conducted on patients hospitalized for asthma exacerbation in 29 hospitals of 29 regions in mainland China during the period 2013 to 2014. Demographic features, pre-admission conditions, exacerbation details, and outcomes were summarized. Risk factors for exacerbation severity were analyzed.RESULTS: There were 3,240 asthmatic patients included in this study (57.7% females, 42.3% males). Only 28.0% used daily controller medications; 1,287 (39.7%) patients were not currently on inhaled corticosteroids. Acute upper airway infection was the most common trigger of exacerbation (42.3%). Patients with severe to life-threatening exacerbation tended to have a longer disease course, a smoking history, and had comorbidities such as hypertension, chronic obstructive pulmonary disease (COPD), and food allergy. The multivariate analysis showed that smoking history, comorbidities of hypertension, COPD, and food allergy were independent risk factors for more severe exacerbation. The number of patients hospitalized for asthma exacerbation varied with seasons, peaking in March and September. Eight patients died during the study period (mortality 0.25%).CONCLUSIONS: Despite enhanced education on asthma self-management in China during recent years, few patients were using daily controller medications before the onset of their exacerbation, indicating that more educational efforts and considerations are needed. The findings of this study may improve our understanding of hospital admission for asthma exacerbation in mainland China and provide evidence for decision-making.

OBJECTIVETo investigate the influence of CCL21 on the invasion and metastasis of colorectal cancer (CRC).

METHODSCCL21 over-expressing CRC cell line was constructed by lentivirus infection and CCL21 low-expressing CRC cell line was constructed by lipofection. The effects of CCL21 on the invasion and metastasis of CRC cells and the stem cell-like phenotype were investigated by Transwell migration, invasion assay, wound healing assay and sphere formation assay.

RESULTSReal-time quantitative PCR and western blot confirmed that the expression of CCL21 was up-regulated by lentiviral transfection and down-regulated by siRNA liposome transfection. In vitro, Transwell assays showed that the invasion and migration in CCL21 over-expressing CRC cells decreased significantly as compared to those of CCL21 low-expressing cells. In wound healing assay, the CCL21 over-expressing CRC cells showed a significantly lower rate of migration. In addition, the sphere formation rate and density of CCL21 over-expressing CRC cells were lower than those with low-expression of CCL21.

CONCLUSIONCCL21 can suppress the migration and invasion of CRC cells and weaken their stem cell-like phenotype.

In this work, a fast and efficient microwave-assisted extraction (MAE) method was developed to extract main bioactive alkaloids from lotus plumue. To optimize MAE conditions, three main factors were selected using univariate approach experiments, and then central composite design (CCD). The optimal extraction conditions were as follows: methanol concentration of 65%, microwave power of 200 W, and extraction time of 260 s. A high performance liquid chromatography–diode array detector (HPLC–DAD) method was established to quantitatively analyze these phytochemicals in different lotus plumule samples and in different part of lotus. Chromatographic separation was carried out on an Agilent Zorbax Extend-C18 column (4.6 mm×150 mm, 3.5 μm). Gradient elution was applied with the mobile phase constituted with 0.1%triethylamine in water (A) and acetonitrile (B): 40%?70% B at 0?8 min, 70%?100% B at 8–9 min, 100% B for 2 min, and then equilibrated with 40%B for 2 min.

Objective To analyze the popular characteristic and drug resistance of Pseudomonas aeruginosa in a hospital of Guiy-ang from January 201 1 to December 2013.Methods The distribution characteristic and drug resistance of Pseudomonas aeruginosa isolated from clinical samples from January 201 1 to December 2013 were analyzed retrospectively.Results A total of 642 strains of Pseudomonas aeruginosa were isolated for three years in our hospital from January 201 1 to December 2013,there was 57.0% isola-ted from sputum specimens,and 27.9% isolated from excreta of wound.The infected endemic area distribution was made up of Or-thopedic Surgery,ICU,Geriatrics Department and Respiratory Department accounting for 22.9%,20.1%,18.8% and 1 5.9% re-spectively.Pseudomonas aeruginosa was most sensitive to polymyxin bacillosporin.The drug resistance rates to Trimethoprim,Am-picillin and Cefazolin were all 100.0%.The drug resistance rates to Ampicillin/sulbactam and Ceftriaxone were 90.0%. Conclusion Pseudomonas aeruginosa is the main cause of lower respiratory tract infections in patients and wound infection and show serious multi-drug resistant,so it is necessary to use drugs reasonably according to the drug susceptibility results.

Objective To investigate the predictive value of abnormal multiples of the median (MoM) of second trimester maternal serum triple screening (STMSTS) markers for adverse pregnancy outcomes.Methods 16 000 singleton pregnancies at 15+0 to 20+6 weeks' gestation who underwent STMSTS between July 2010 and January 2013 in the First Hospital of Jilin University were recruited.Maternal serum AFP,free β-hCG (F-β-hCG) and unconjugated estriol (uE3) levels were measured using time-resolved fluoroimmunoassay,and then convened to MoM.LifeCycle 3.2 software was used to calculate risk,and a risk value greater than 1 in 270 or 1 in 350 was considered as high risk for trisomy 21 syndrome (Down syndrome,DS) and trisomy 18 syndrome (Edwards syndrome,ES),respectively.MoM of AFP more than 2.5was considered high risk for open neural tube defect (ONTD).Amniocentesis and karyotyping,ultrasound screening were advised for high risk women.AFP,F-β-hCG higher than 2.0 MoM or uE3 lower than 0.5MoM was considered as abnormal,respectively.The MoM of STMSTS marker between women with adverse pregnancy outcome and with normal outcome was compared.Results (1) The median MoM of AFP,F-β-hCG and uE3 was 0.91 MoM,0.94 MoM and 1.05 MoM,respectively.Of the 16 000 pregnant women,there was no statistical difference in the median MoM of triple screening marker at different weeks of gestation (P＞0.05).The positive rate of DS,ES and ONTD in women ≤35 years old (n=14 972) was 4.03％ (603/14 972),0.36％(54/14 972) and 0.29％(44/14 972) respectively.And in women＞35 years old(n=1 028),the positive rate was 24.51％ (252/1 028),1.95％ (20/1 028) and 0.78％ (8/1 028),respectively.There was a statistically significant difference of positive rate between the two groups(P＜0.05).(2) 9 cases of DS,1 case of ES and 1 ease of ONTD were found in the high risk group,and 2 cases of DS in the low risk group.The detection rate of DS,ES and ONTD was 9/11,1/1 and 1/1 respectively; and the positive predictive value was 1.05％(9/855),1.35％(1/74) and 1.92％(1/52),respectively.(3)The incidence of adverse outcome (group 1) was 1.49 ％(239/16 000).7 760 pregnant women in this study were healthy during pregnancy,so were their fetuses (group 2).There were significant differences in the age at delivery,body weight and markers' MoM of STMSTS between the two groups(P＜0.01).(4) In group 1,the rate of abnormal MoM of AFP or F-β-hCG was 7.95％(19/239) and 23.85％ (57/239),and the abnormal rate of MoM of uE3 was 4.18％(10/239).The rate of two abnormal MoM of markers was 5.02％(12/239); the rate that all three MoM were abnormal was 0.84％(2/ 239).However,in group 2,the rate of two abnormal MoM of markers was 0.14 ％(11/7 760); and the rate that all three MoM were abnormal was 0.There was a significant difference of abnormal MoM of maternal serum marker between the two groups (P＜0.01).Conclusions There is a relationship between abnormal marker of STMSTS and adverse outcomes.STMSTS show a high value in the detection of DS,ES and ONTD.

Objective To analyze the clinical features of pulmonary embolism(PE) after urologic surgery in order to provide the theory base for preventing pulmonary embolism Methods CNKI database was used to look for our subjects who were with PE after urologic surgery from January 2005 to December 2011.Ten cases were selected.Three related patients simultaneously in Xuancheng Central Hospital were also recruited as our subjects.The information of diagnosis and treatment information and clinical features were collected.Results Among the 13 patients,3 were women and 10 were men with confirmed PE.Their age ranged from 48 to 79 years old and the average was 61.Among the 13 patients,2 conducted routine surgery,and the other 11 conducted mini-invasion operation.The 13 patients underwent PE from 2 to 18 days after urologic surgery and 7 patients (53.85％) died of PE.Conclusion No specificity of clinical feature for PE was found to contribute to cure rate.Early diagnosis and prevention of PE are important,and anticoagulant treatment and immediate thrombolytic are critical.
