Objective:To explore the value of serum procalcitonin (PCT), amylase (AMY), albumin (ALB) and lactate dehydrogenase (LDH) in the clinical diagnosis and evaluation of severe acute pancreatitis (SAP).Methods:A total of 70 patients with acute pancreatitis treated in Yancheng First People′s Hospital from January 1, 2020 to December 31, 2022 were enrolled as pancreatitis group. According to disease severity, they were divided into mild group (22 cases) and severe group (48 cases). A total of 70 controls during the same period were enrolled as control group. The general data of all the objects were collected at enrollment. The levels of plasma PCT, AMY, ALB and LDH were detected. The diagnostic value of the above indexes for SAP and their evaluation value for disease severity were analyzed by receiver operating characteristic (ROC) curves.Results:The levels of serum PCT, AMY and LDH in the pancreatitis group were significantly higher than those in the control group: (3.14 ± 0.67) μg/L vs. (0.82 ± 0.21) μg/L, (602.53 ± 199.47) U/L vs. (99.97 ± 30.85) U/L, (767.24 ± 198.73) U/L vs. (423.61 ± 59.19) U/L, P<0.05; while ALB was significantly lower than that in the control group: (33.47 ± 6.98) g/L vs. (45.79 ± 6.12) g/L, P<0.05. ROC curves analysis showed that area under the curve (AUC) values of PCT, AMY, LDH, ALB and combined detection in the diagnosis of acute pancreatitis were 0.783, 0.792, 0.697, 0.732 and 0.915, respectively. The levels of serum PCT and LDH in the mild group were significantly lower than those in the severe group: (2.76 ± 0.44) μg/L vs. (3.59 ± 0.61) μg/L, (507.06 ± 131.67) U/L vs. (848.95 ± 207.79) U/L, P<0.05; while ALB was significantly higher than that in the severe group: (35.39 ± 4.73) g/L vs. (32.64 ± 5.09) g/L, P<0.05. ROC curves analysis showed that the AUC values of PCT, LDH, ALB and combined detection for evaluating disease severity were 0.668, 0.749, 0.741 and 0.959, respectively. The evaluation value of combined detection was significantly higher than that of single index ( P<0.05). Conclusions:The levels of serum PCT, AMY and LDH are abnormally increased, while ALB level is abnormally decreased in patients with acute pancreatitis, and which all can be applied for clinical diagnosis. PCT, LDH and ALB can be applied for disease evaluation.

Objective:To study the epidemic characteristics of human brucellosis in Yunnan Province, and to provide a reliable scientific basis for formulating accurate prevention and control strategies of brucellosis.Methods:The epidemic data of human brucellosis in Yunnan Province from January 2019 to December 2021 were collected from the information system of the China Center for Disease Control and Prevention, as well as annual monitoring data on brucellosis reported by various states (municipalities) in Yunnan Province. Descriptive epidemiological methods were adopted to analyze the epidemic situation, distribution characteristics (time, region, population), and serological and pathogenic monitoring results of brucellosis.Results:From 2019 to 2021, 1 408 cases of brucellosis were reported in Yunnan Province, with an average annual incidence of 1.00/100 000. The number of cases increased from 321 in 2019 to 701 in 2021, and the incidence increased from 0.68/100 000 in 2019 to 1.50/100 000 in 2021. The onset time was mainly from April to September (857 cases). The top 3 regions with the highest number of reported cases were Kunming City (483 cases), Qujing City (379 cases), and Honghe Hani and Yi Autonomous Prefecture (281 cases), accounting for 81.18% (1 143/1 408) of the total number of cases. The age of onset was mainly 20 - < 70 years old, accounting for 89.70% (1 263/1 408). There were 958 males and 450 females, with a sex ratio of 2.13 ∶ 1.00. Farmers were the main occupation, accounting for 84.02% (1 183/1 408). From 2019 to 2021, a total of 26 280 serum samples from key populations of brucellosis were monitored in Yunnan Province, with 572 positive serological tests and a positive rate of 2.18% (572/26 280). A total of 169 strains of Brucella were isolated from blood samples from hospitals throughout the province, including 155 strains of sheep type 3 and 14 strains of sheep type 1. Conclusions:From 2019 to 2021, the incidence of human brucellosis in Yunnan Province has been on the rise, with a high incidence in summer and autumn. The main population affected is young and middle-aged male farmers. Therefore, it is necessary to strengthen disease monitoring and health education for key populations during the high incidence season.

Objective:To investigate the trend of radiological diagnostic examination frequency and the related influencing factors in a general hospital in recent four years.Methods:The hospital information system and the radiology information system were used to collect the information on the numbers of the outpatients, the emergency patients, and the inpatients and the radiology examination information from 2019 to 2022. The examination frequency and proportion of various imaging equipment were counted by using the perspective table of data, and the examination items and the proportion of the radiological diagnostic examinations were calculated. The positive rates of the radiological examinations were measured from 2019 to 2022. The gender and age distribution of the patients were analyzed. Spearman correlation analysis was used to analyze the relationships between the numbers of the patients undergoing radiological examinations and the numbers of the outpatients, emergency patients and the inpatients.Results:The annual frequency of radiological diagnostic examinations from 2019 to 2022 were 307 306, 245 418, 317 250 and 325 625, respectively, with a total of 1 195 599. Among them, the proportions of CT, X-rays, bedside X-rays, bone density, gastrointestinal imaging and mammography were 59.74%, 38.04%, 1.39%, 0.42%, 0.21% and 0.19%, respectively. In each year, the proportion of CT in all radiological diagnostic examinations was 49.58%, 63.40%, 60.40% and 65.20%, respectively. The frequency of emergency CT and emergency chest CT was correlated with the number of emergency patients( r =0.63, 0.61, P<0.05), and the frequency of non-emergency CT was correlated with the number of outpatients and inpatients ( r =0.61, 0.66, P<0.05). The positive rates of the CT examinations were higher than 80% except the lowest of 79.95% in 2021. Conclusions:Radiological examinations especially CT examinations have increased significantly, and played an important role in the diagnosis of diseases. However, attention should be paid to the Justification of the CT examinations. Timely statistical analysis of radiological examination information can provide data supports and references for scientific management of radiological examinations.

The main population is middle-aged and elderly male farmers and herdsmen.

In order to evaluate the efficacy and safety of submucosal tunneling endoscopic resection (STER) for the treatment of multiple submucosal tumors (SMT) in the upper gastrointestinal tract, data of 24 cases with upper gastrointestinal SMT (including 56 SMT lesions) treated at Taizhou Municipal Hospital and Shanghai East Hospital from January 2016 to June 2021 were collected for retrospective observation. The treatment effect, occurrence of major adverse events and follow-up results were analyzed. The results showed that 19 cases (79.2%) underwent tumor resection through one tunnel, and 5 cases (20.8%) underwent tumor resection through two tunnels. The length of the tunnel was 3-12 cm, with an average of 6.2 cm. The surgical time ranged from 19 to 130 minutes, with an average of 55.6 minutes. The overall resection rate was 89.29% (50/56). The hospitalization time was 2-7 days, with an average of 3.5 days. Major adverse events occurred in 2 cases (8.3%), all of which were mucosal injuries, and were cured with titanium clips and self expanding metal sealing stents. During a follow-up period of 6-64 months, with an average of 32.0 months, there was no residual tumor, tumor implantation tunnel, local recurrence, distant metastasis or death. To sum up, STER is safe and feasible for the treatment of multiple SMT in the upper gastrointestinal tract. The main resection method is single tunnel, and double tunnel is required for multiple SMT far apart.

Objective: To explore the role and mechanism of long noncoding RNA(lncRNA) AC005062.1 in colorectal cancer(CRC) cell proliferation and apoptosis. Methods: The analysis of GSE84983 and GSE 104364 was used to indicate the expression level lncRNA AC005062.1 in CRC. The tumor tissues(tumor group) and adjacent tissues(control group) of patients undergoing CRC surgery in the hospital tumor surgery department were collected. Eight pairs of tissues were randomly selected, and qPCR was used to detect the expression of lncRNA AC005062.1 in CRC tissues and paired adjacent tissues in the two groups. After using siRNA to down-regulate the expression of lncRNA AC005062.1 in CRC cells, CCK-8 assay was used to detect cell proliferation in two groups, flow cytometry was used to detect cell cycle and apoptosis in two groups, wound scratch test was used to detect cell migration in two groups, and the lncRNA was determined. The database was used to compare the localization of lncRNA AC005062.1 and MACC1 genes on staining. The expression levels of MACC1 transcription and protein levels in the control group and tumor group were detected by qPCR and Western blot, respectively. The lncRNA AC005062.1 in CRC cells was down-regulated, and the expression levels of MACC1 transcription and protein levels in the two groups of cells were detected by qPCR and Western blot, respectively. Results: The database analysis of GSE84983 and GSE104364 and the detection results of the two groups indicated that the lncRNA AC005062.1 was highly expressed in CRC. After down-regulation of lncRNA AC005062.1, the results of CCK-8 experiments showed that the proliferation rate of HT29 cells in the down-regulation group decreased. Flow cytometry showed that the number of apoptosis of HT29 cells in the down-regulated group increased, the proportion of G1 phase increased, and the proportion of S phase and G2 phase decreased. Western blot experiments showed that the expressions of cleaved-caspase3 and Bax in the down-regulated HT29 cells increased, while the expression of Bcl-2 decreased. Wound scratch experiments showed that the migration rate of HT29 cells in the down-regulated group was lower than that in the control group. The analysis of UCSC to compare the location of lncRNA ac005062.1 and MACC1 on chromosomes showed that they were located very close together. MACC1 was highly expressed in CRC and down-regulated lncRNA AC005062.1 expression in HT29 cells could reduce the expression of MACC1. Conclusion lncRNA AC005062.1 can inhibit the proliferation, cycle and migration of HT29 cells, and promote its apoptosis by regulating the expression of MACC1 in CRC.

Objective: To investigate the ameliorative effects of Mushroom on adipose tissue inflammation and glucolipid metabolism in mice fed a high-fat diet, and to provide a theoretical basis for the mechanisms of Mushroom regulating glucolipid metabolism and inflammatory responses. Methods: C57 BL/6 J mice were fed with normal diet(LF) group, high-fat diet(HF)group and high-fat diet + Mushroom(HF+Mushroom) group for 15 weeks.Then, body weight subcutaneous and epididymal white adipose tissue weight were measured. The morphological changes of adipose tissues were compared by HE staining, and the expression of genes related to inflamation, glycolysis and fatty acid oxidation pathways were detected by RT-PCR and Western blot. Results: Compared with the LF group, the HF group had increased body weight, increased subcutaneous and epididymal white fat weight and adipocyte size, and upregulated expression of tumor necrosis factor-α(TNF-α), interleukin-6(IL-6), monocyte chemoattractant protein-1(MCP-1), CD68, inducible nitric oxide synthase(iNOS), pyruvate kinase(PK), phosphofructokinase(PFK), hypoxia inducible factor-1α(HIF-1α) and peroxisome proliferator activated receptor alpha(PPARα) in adipose tissues, while the expression of carnitine palmitoyl transferase-1 A(CPT-1 A), cytochrome P450 4 a10(CYP4 a10) and medium-chain acyl-coenzyme a dehydrogenase(MCAD) were downregulated(P<0.05). Compared with the HF group, Mushroom supplementation reduced body weight, adipose tissue weight and adipocyte size, and downregulated the expression of pro-inflammatory factors and glycolytic pathway-related factors in adipose tissues, while the expression of fatty acid oxidation pathway-related factors were upregulated(P<0.05). Conclusion Mushroom can ameliorate inflammation and disorders of glycolipid metabolism in adipose tissues of obese mice.

Objective:To investigate the effect of gene polymorphism of β1 adrenergic receptor (β1-AR) G1165C and A145G locus on myocardial hypertrophy and the efficacy in patients with hypertension.Methods:Two hundred and twenty-seven cases of patients with hypertension admitted to Binhai County People′s Hospital from January to December 2019 were enrolled. Among them, there were 113 cases of hypertension with myocardial hypertrophy and 114 cases of hypertension without myocardial hypertrophy. In addition, 115 patients with normal physical examination during the same period were selected as the control group. DNA in the peripheral blood leukocytes was extracted, polymerase chain reaction-restriction fragment length polymorphism method was used to detect β1-AR G1165C and A145G locus gene polymorphism, and the differences in the efficacy of β blockers in hypertensive patients with different genotypes were compared.Results:There was no statistically significant differences in the distribution of β1-AR A145G genotypes among the three groups ( P>0.05). Compared with the healthy control group, the frequency of Gly/Gly genotype carrying β1-AR G1165C locus was higher in hypertension with myocardial hypertrophy group, and the frequency of Gly/Arg and Arg/Arg gene were lower; compared with hypertension without myocardial hypertrophy group, the frequency of Gly/Arg+Gly/Gly gene in hypertension with myocardial hypertrophy group was higher; taking Arg/Arg genotype as the control group, carrying Gly/Gly genotype could increase the risk of cardiac hypertrophy in hypertensive patients by 3.159 times ( OR = 3.159, 95% CI 1.240 - 7.412, P<0.05).The frequency of G1165C allele Arg in the hypertension with myocardial hypertrophy group was significantly lower than that in the control group and the hypertension without myocardial hypertrophy group ( P<0.05); the frequency of G1165C allele Gly was significantly higher than that in the control group and the hypertension without myocardial hypertrophy group ( P<0.05); taking Arg/Arg genotype as the control, carrying Gly/Gly genotype could increase the risk of cardiac hypertrophy in hypertensive ( OR = 3.417, 95% CI 1.357 - 7.965, P<0.05). The left ventricular mass index of Gly/Gly genotype patients was (120.38 ± 28.41) g/m 2, which was significantly higher than (99.76 ± 25.16) g/m 2 and (90.30 ± 19.54) g/m 2 of Gly/Arg and Arg/Arg, with statistically significant differences ( F = 10.89, P<0.01). After the treatment, the resting heart rate, systolic blood pressure, diastolic blood pressure and mean arterial blood pressure of patients with G1165C allele Arg hypertension with myocardial hypertrophy were lower than those with G1165C allele Gly, with statistically significant differences ( P<0.05). Conclusions:β1-AR G1165C gene polymorphism is related to the risk of myocardial hypertrophy in hypertensive patients. Carrying the G1165C allele Gly may increase the risk of susceptibility to cardiac hypertrophy, and β-blockers are more effective in hypertensive patients with myocardial hypertrophy who carry the G1165C allele Arg.
