Despite the high mortality rate due to spontaneous splenic rupture with DIC, the patient was successfully treated and the details of the case are presented in this report.

[The application of ultrasound in the diagnosis of small bowel volvulus in adults].

Objective: To analyze the ultrasound characteristics of small bowel volvulus among adults and to investigate the value of ultrasound in the diagnosis of small bowel volvulus. Methods: Totally 34 adults with small bowel volvulus confirmed by clinical diagnosis or surgery and who underwent ultrasound examination at Peking Union Medical College Hospital from August 2017 to October 2022 were enrolled, including 19 males and 15 females, aged (55.0±21.8) years (range: 19 to 94 years). The clinical characteristics, CT images and ultrasound images of the patients were retrospectively reviewed, and the ultra, sound features of small bowel volvulus and its diagnostic efficacy were analyzed. Results: Abdominal pain was the typical clinical symptom of all patients. Other symptoms included 21 cases of abdominal distension, 19 cases of nausea and vomiting, and 13 cases of cessation of passage of stool or flatus. Eight patients had signs of peritonitis and 22 patients had abnormal bowel sounds. Twenty patients had a history of abdominal surgery. Twenty-seven patients underwent surgery for intestinal obstruction, and the remaining 7 patients improved after conservative treatment. All cases were evaluated by ultrasound, 11 cases showed a "whirl sign" and were diagnosed as small bowel volvulus, the diagnostic accuracy rate was 32.4% (11/34), ultrasound simultaneously diagnosed intestinal obstruction in 21 cases, 17 cases of abdominal effusion, 4 cases of intestinal wall thickening, 2 cases of abdominal mass, 1 case of intussusception, 1 case of right sided inguinal hernia. CT and ultrasound had a consistent positive discovery in 88.2% (30/34) of all the patients. Conclusion: Ultrasound is valuable in the diagnosis of small bowel volvulus and the evaluation of complications.

Insulin Resistance-Varying Associations of Adiposity Indices with Cerebral Perfusion in Older Adults: A Population-Based Study.

OBJECTIVES: Excessive accumulation of adipose tissue may accelerate brain aging, but the underlying mechanisms are poorly understood. Several adiposity indices were proposed to assess obesity, while their linkage with brain health in older adults remained unclear. Here we aimed to examine the associations of adiposity indices with global and regional cerebral blood flow (CBF) in older adults, while considering insulin resistance. DESIGN: This was a cross-sectional population-based study that included older adults derived from the baseline participants in the ongoing Multimodal Interventions to Delay Dementia and Disability in rural China (MIND-China) study. SETTING AND PARTICIPANTS: The study included 103 Chinese rural-dwelling older adults (age≥60 years; 69.9% women) who underwent brain magnetic resonance imaging scans. METHODS: We estimated eight adiposity indices based on anthropometric measures. We automatically quantified global and regional CBF using the arterial spin labeling scans. Insulin resistance was assessed using the triglyceride-glucose index and then dichotomized into high and low levels according to the median. Data were analyzed using general linear model and voxel-wise analysis. RESULTS: Of the eight examined adiposity indices, only higher waist-to-height ratio (WHtR) and body roundness index (BRI) were associated with reduced global CBF (multivariable-adjusted ß-coefficients and 95%CI: -1.76; -3.25, -0.27 and -1.77; -3.25, -0.30, respectively) and hypoperfusion in bilateral middle temporal gyri, angular gyri and superior temporal gyri, left middle cingulum and precuneus (P<0.05). There were statistical interactions of WHtR and BRI with levels of insulin resistance on CBF, such that the significant associations of higher WHtR and BRI with lower global and regional CBF existed only in people with high insulin resistance (P<0.05). CONCLUSION: Higher WHtR and BRI are associated with cerebral hypoperfusion in older adults, especially in people with high insulin resistance. This may highlight the pathological role of visceral fat in vascular brain aging.

[Application of enhanced recovery after surgery in perioperative management of patients with gallbladder carcinoma].

Objective: To investigate the efficacy and safety of enhanced recovery after surgery (ERAS) in perioperative management of patients with gallbladder carcinoma. Methods: The data of the patients with gallbladder carcinoma admitted at Peking Union Medical College Hospital between January 2017 and December 2021 were analyzed retrospectively. There were 69 males(42.1%) and 95 females(57.9%),with age of (64.0±10.3) years(range:37 to 89 years). Patients were divided into ERAS group(n=53) and normal group(n=111) according to whether they were treated with ERAS measures during the perioperative period.The basic characteristics of the two groups were matched by propensity score matching,and then the perioperative information was compared between the two groups. Categorical variables were presented as absolute numbers or frequencies. Differences between study groups were analyzed using χ2 test, Fisher's exact test, t-test, or Mann-Whitney U test, as appropriate. Results: Each group had 45 patients after propensity score matching with well-balanced basic characteristics. There was no difference in basic characteristics, operation time,bleeding,complication,and hospitalization expenses between two groups(all P>0.05). Compared with the normal group,time of ambulation (M(IQR)) (1(1) day vs. 2(2) days;Z=-3.839,P<0.01),postoperative anal exhaust time (2(1) days vs. 3(1) days;Z=-3.013,P=0.003),feeding time(2(1) days vs. 2(1) days;Z=-3.647,P<0.01),postoperative (5(2) days vs. 7(4) days;Z=-3.984,P<0.01) and total(8(4) days vs. 13(6) days;Z=-3.605,P<0.01) hospitalization time were shorter in ERAS group. Postoperative complications occurred in 12 patients. According to the Clavien-Dindo classification,6,4,and 2 patients were classified as grade Ⅰ,Ⅱ,and Ⅲa,respectively. Conclusion: The ERAS measures is safe and effective for perioperative management of patients with gallbladder carcinoma, enhancing patient recovery and shortening hospitalization time without increasing complication or hospitalization cost.

ABSTRACT: Objective To investigate the population genetic data of 47 autosomal insertion/deletion （InDel） polymorphism genetic markers involved in AGCU InDel 50 kit in Guangdong Han, Guangxi Zhuang, Guangxi Yao, Guangxi Jing, and Guangxi Mulam, and to evaluate their application in forensic DNA identification. Methods Multiplex amplification of the 768 unrelated individuals from the 5 ethnic groups mentioned above was performed with the AGCU InDel 50 kit. Genotyping was carried out by 3500xL gene analyzer, population genetic parameters were gathered and polymorphism analysis was performed. Results No linkage disequilibrium was found among 47 autosomal InDel loci in the 5 ethnic groups. The distribution of genotype frequency of 47 autosomal InDel loci confirmed to the Hardy-Weinberg equilibrium in Guangdong Han and Guangxi Zhuang. Except for rs139934789, the other 46 loci confirmed to the Hardy-Weinberg equilibrium in Guangxi Yao, Guangxi Jing, and Guangxi Mulam. The results of genetic variation analysis among the populations showed that 1.12% of genetic variation was caused by ethnic group differences. The cumulative discrimination power of 47 autosomal InDel loci for the 5 ethnic groups were all above 0.999 999 999 999 999. The cumulative probability of exclusion for each ethnic group was less than 0.999 9. The two Y-InDels were identified in all male individuals and were absent in all female individuals. Conclusion Except for rs139934789, the other 46 InDel loci have a relatively good genetic polymorphism in the 5 Chinese ethnic groups, and can be used for forensic individual identification and as effective supplements for paternity testing.

Linc00703 suppresses non-small cell lung cancer progression by modulating CyclinD1/CDK4 expression.

OBJECTIVE: The aim of this study was to detect the expression of linc00703 in non-small cell lung cancer (NSCLC), and to explore the biological function and potential molecular mechanism of linc00703 in NSCLC using in vitro experiments. PATIENTS AND METHODS: The carcinoma tissues and para-carcinoma tissues were collected from 32 patients diagnosed with NSCLC, from which the RNA was extracted. The relative expression of linc00703 in NSCLC tissues was detected via quantitative reverse transcription-polymerase chain reaction (qRT-PCR). The NSCLC cells and normal human bronchial epithelial cells were selected, in which the relative expression of linc00703 was determined via qRT-PCR. Next, the linc00703 overexpression plasmids were designed and synthesized, and then transiently transfected into NSCLC cells. After 48 h, the overexpression efficiency was detected. Finally, the changes in cell proliferation, apoptosis, cycle distribution and expressions of downstream molecular markers were determined using cell counting kit-8 (CCK8) assay, colony formation assay, flow cytometry and Western blotting, respectively, after overexpression of linc00703 in NSCLC cells. RESULTS: The results of qRT-PCR revealed that the expression of linc00703 was down-regulated by 5.14 times on average in 29 out of 32 cases of NSCLC tissues, and it was also down-regulated in NSCLC cells. Besides, it was found through CCK-8 assay, colony formation assay and flow cytometry that after overexpression of linc00703 in NSCLC cells, the cell proliferation was inhibited, the apoptosis was enhanced, and the cell cycle was arrested in G1/G0 phase. Furthermore, the results of Western blotting showed that after overexpression of linc00703, the protein expressions of cyclinD1 and cyclin-dependent kinase 4 (CDK4) declined, while those of cyclinE1 and CDK2 did not change. CONCLUSIONS: The expression of linc00703 is down-regulated in NSCLC, and it suppresses the occurrence and development of NSCLC via mediating the expression of cyclinD1/CDK4.

LINC01093 promotes proliferation and invasion of non-small cell lung cancer cells via targeting akt signaling pathway.

OBJECTIVE: To explore the expression of LINC01093, a long non-coding ribonucleic acid (lncRNA) in non-small cell lung cancer (NSCLC) tissues, and cells and its regulatory role in NSCLC cell proliferation and invasion. PATIENTS AND METHODS: The expression of LINC01093 in NSCLC tissues and cells was detected via quantitative Reverse Transcription-Polymerase Chain Reaction (qRT-PCR) experiment. The specific sequences interfering in LINC01093 were designed and transiently transfected into A549 and SPCA-1 cells using LipofectamineTM 2000, and 48 later, the transfection efficiency was detected. Moreover, the impacts of small interfering (si)-LINC01093 on NSCLC cell proliferation were observed via methyl thiazolyl tetrazolium (MTT) and colony forming assays, the influence of LINC01093 on the cycle distribution of NSCLC cells was determined through flow cytometry, and the changes in the invasion and migration abilities of NSCLC cells were evaluated via transwell assay after interfering in the expression of LINC01093. Finally, the expression changes of the molecular markers in the protein kinase B (Akt) signaling pathway in the downstream of LINC01093 were detected via Western blotting. RESULTS: According to the results of qRT-PCR, the relative expression level of LINC01093 was up-regulated in NSCLC tissues and cells. After interfering in the expression of LINC01093, the results of MTT and colony forming assays revealed that the proliferation ability of NSCLC cells was weakened, according to the findings in the flow cytometry, the cells were arrested in G1/0 phase, the transwell assay results manifested that the cell migration and invasion abilities were weakened, and the results of the Western blotting suggested the changes in the expressions of molecular markers in the Akt signaling pathway. CONCLUSIONS: The expression of LINC01093 is upregulated in NSCLC tissues and cells, and it facilitates the proliferation, invasion, and metastasis of NSCLC cells via the Akt signaling pathway.

Long noncoding RNA SNHG14 exerts oncogenic functions in lung adenocarcinoma through acting as a sponge to miR-613.

OBJECTIVE: Lung adenocarcinoma is one of the most ordinary malignant tumors. Recent researches have proved that long noncoding RNAs (lncRNAs) are vital factors in many diseases. In this work, lncRNA SNHG14 was studied to identify its function in the development of lung adenocarcinoma. PATIENTS AND METHODS: Real Time-quantitative Polymerase Chain Reaction (RT-qPCR) was utilized to detect SNHG14 expression in paired lung adenocarcinoma patients' tissue samples and cells. Then, the function of SNHG14 was detected through MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) assay, colony formation assay, and transwell assay in vitro. Besides, mechanism assays and the interaction between SNHG14 and miR-613 were conducted. RESULTS: SNHG14 was remarkably higher-expressed in lung adenocarcinoma tissues than in adjacent samples. Moreover, cell proliferation and invasion of lung adenocarcinoma were promoted via overexpression of SNHG14, while cell proliferation and invasion of lung adenocarcinoma were inhibited via silence of SNHG14. Moreover, RT-qPCR results revealed that miR-613 was downregulated via overexpression of SNHG14, while miR-613 was upregulated via knockdown of SNHG14. Further experiments showed that miR-613 was also a direct target of SNHG14 in lung adenocarcinoma. CONCLUSIONS: Our study suggests that SNHG14 enhances lung adenocarcinoma cell proliferation and invasion via targeting miR-613, which indicates that SNHG14 may be a potential therapeutic target in lung adenocarcinoma.

MicroRNA-218 regulates the epithelial-to-mesenchymal transition and the PI3K/Akt signaling pathway to suppress lung adenocarcinoma progression by directly targeting BMI-1.

OBJECTIVE: To investigate the role of miR-218 in the development of lung adenocarcinoma (LA) and its underlying mechanism. PATIENTS AND METHODS: Fifty-two pairs of human LA samples and adjacent para-carcinoma tissue samples were collected from our hospital between June 2015 and March 2017. Meanwhile, one normal human pulmonary epithelial cell line BEAS-2B and four human LA cell lines (H1299, PC-9, A549, and SPC-A1) were cultured. The cells' ability of proliferation and migration was detected by MTT assays and Transwell assays, respectively. The target gene was clarified by dual-luciferase reporter assay. The related protein and mRNA expression levels were detected by immunohistochemistry (IHC), Western blot and quantitative real-time polymerase chain reaction (qRT-PCR), respectively. At last, the tumor xenograft model was made for further exploring the mechanism. RESULTS: MiR218 expressions were notably reduced in LA tissues in comparison with controls. In addition, the declined miR218 expressions were correlated with the poor OS and worse clinicopathological parameters of LA patients. Furthermore, miR218 overexpression could suppress the proliferation, migration and invasion capacities of LA cells via regulation of PI3K/Akt signaling pathway and epithelial-mesenchymal transition (EMT) respectively. Results in the current study also revealed that miR-218 upregulation could suppress the tumor growth rate and tumor size of LA mice. B-lymphoma Moloney murine leukemia virus insertion region-1 (BMI-1) was confirmed to be a direct target for miR-218 and upregulated in LA tissues, which indicated the poor prognosis of LA patients. CONCLUSIONS: MiR-218 exerted anti-tumor functions in LA partially via the regulation of BMI-1, suggesting that BMI-1/miR-218 axis may provide a novel insight into tumorigenesis and the basis for the development of miRNA-targeting therapies against LA.

Polyoxometalate SbW9 regulates proliferation and apoptosis of NSCLC cells via PTEN-dependent AKT signaling pathway.

OBJECTIVE: To explore the influence of polyoxometalate SbW9 on proliferation and apoptosis of non-small cell lung cancer (NSCLC) cells and its mechanism. MATERIALS AND METHODS: NSCLC cell lines A549 and PC9 were treated with 50 µM polyoxometalate. Then, the proliferation of NSCLC cells was detected via 2,3-bis(2-methoxy-4-nitro-5-sulfophenyl)-5-[(phenylamino)carbonyl]-2H-t tetrazolium hydroxide (XTT) assay and colony formation assay; the apoptosis of NSCLC cells was detected via flow cytometry and terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL); and the expression of apoptosis-related proteins, B-cell lymphoma-2 (Bcl-2), and Bcl-2 associated X protein (Bax), was detected via Western blotting. Moreover, the protein expression levels of phosphatase and tensin homolog deleted on chromosome ten (PTEN), phosphorylated-protein kinase B (P-AKT) and total AKT (T-AKT) were detected via Western blotting. RESULTS: The polyoxometalate inhibited the proliferation of A549 and PC9 cells in a concentration-dependent manner (5-100 µM) (p<0.05), and it (50 µM) also inhibited the proliferation of both cells in a time-dependent manner (0-72 h) (p<0.05). The results of colony formation assay revealed that the polyoxometalate (50 µM) could significantly inhibit the colony formation of A549 and PC9 cells (p<0.05). The results of flow cytometry and TUNEL staining showed that the polyoxometalate (50 µM) significantly induced the apoptosis of A549 and PC9 cells (p<0.05). According to further studies, the polyoxometalate (50 µM) inhibited the expression of anti-apoptotic gene Bcl-2 and promoted the expression of pro-apoptotic gene Bax. Besides, the Western blotting results manifested that the polyoxometalate could activate the expression of PTEN and inhibit the phosphorylation of downstream AKT (p<0.05). CONCLUSIONS: The polyoxometalate can activate the expression of PTEN to inhibit the phosphorylation of AKT, ultimately inhibiting the proliferation and inducing the apoptosis of NSCLC cells. Therefore, the polyoxometalate is expected to become a novel drug for the clinical treatment of NSCLC.

[miRNA-96-5p inhibits the proliferation and migration of gastric cancer cells by targeting FoxQ1].

Objective: To investigate the role of microRNA-96-5p in the proliferation and invasion of gastric cancer cells and its molecular mechanism. Methods: From June 2015 to January 2017, 53 resected specimens were collected. The transcriptional levels of microRNA-96-5p and forkhead box Q1 (FoxQ1) in gastric cancer tissues and the matched para-cancerous tissues were quantified by quantitative real-time PCR (qRT-PCR). The expression of FoxQ1 protein was also detected by immunohistochemistry (IHC). The relationship between microRNA-96-5p expression and the clinicopathological features of gastric cancer and its correlation with FoxQ1 expression were analyzed. The expressions of miRNA-96-5p in gastric cancer tissue and adjacent normal tissue were detected by qRT-PCR. miRNA-96-5p mimics was transfected to BGC-823 gastric cancer cells. The effects of miRNA-96-5p on cell proliferation and invasion were detected by cell counting kit-8 (CCK-8) assay and Transwell assay, respectively. The protein expressions of FoxQ1, E-cadherin and vimentin were determined by western blot. The relationship between FoxQ1 and miRNA-96-5p expressed in BGC-823 cells was detected by dual-luciferase reporter assay. Results: The median expression of miRNA-96-5p in gastric cancer tissue was 1.05, significantly lower than 3.23 of para-cancerous tissues (P<0.05). The positive rate of FoxQ1 expression in gastric cancer tissue was 71.7%, significantly higher than 28.3% of para-cancerous tissues (P<0.05). The expression of FoxQ1 was negatively corelated with the level of miRNA-96-5p (r=-0.613, P=0.006). The expression of miRNA-96-5p in gastric cancer cell BGC-823 was significantly decreased compared with normal gastric epithelial cell (0.96±0.08 vs 2.84±0.15, P<0.05). The results of CCK-8 assay and Transwell assay showed that overexpression of miRNA-96-5p significantly reduced the proliferation and invasion abilities of gastric cancer cells (P<0.05). Overexpression of miRNA-96-5p decreased the protein level of FoxQ1. Moreover, it upregulated the expression of E-cadherin and downregulated the expression of vimentin. The result of dual-luciferase-3'-UTR reporter assay confirmed that miRNA-96-5p binds to the 3'UTR of FoxQ1. Conclusion: miRNA-96-5p may suppress the proliferation, migration and epithelial-mesenchymal transition (EMT) of gastric cancer cell by down-regulation of FoxQ1.

Objective: To investigate the serum levels of interleukin (IL)-6 and -8 in patients with chronic periodontal disease and acute exacerbation of chronic obstructive pulmonary disease (AECOPD) and the possible relationship between IL-6 and IL-8 with two diseases. Methods: A total of 40 cases of healthy subjects (control group 1) from graduate school of Anhui Medical University, and 120 cases (40 cases in each of the 3 groups) of eligible patients were collected, of which 40 were patients with chronic periodontal disease and AECOPD (experimental group) from Department of Respiratory Medicine, The First Affiliated Hospital of Anhui Medical University and Anhui NO.2 Provincial People's Hospital, 40 were patients with chronic periodontal disease (control group 2) from Department of Stomatology, The First Affiliated Hospital of Anhui Medical University, 40 were patients with AECOPD (control group 3) from Department of Respiratory Medicine, The First Affiliated Hospital of Anhui Medical University. The clinical indicators of all subjects were collected, including tooth mobility degree, probing depth (PD), bleeding index (BI), attachment level (AL), vital capacity max (VC Max), forced expiratory volume in first second (FEV1) and forced expiratory volume in first second to forced vital capacity (FEV1/FVC) ratio. Enzyme linked immunosorbent assay (ELISA) was used to detect the serum levels of IL-6 and IL-8 in the subjects of four groups. Results: The attachment levels had no significant differences between experimental group and control group 2 (P>0.05). The pulmonary function indices of experimental group including VC MAX% pre[(56.1±11.1)%], FEV1 %pre [(44.8±12.2)%], FEV1/FVC(%) [(56.8±11.4)%] were significantly different from those in control group 3 [(66.3±10.1)%, (53.0±10.4)%, (66.5±8.2)%, respectively]. The IL-6 levels of experimental group, control groups 1, 2 and 3 were (14.4±3.9), (2.1±1.1), (4.8±1.9) and (8.6±1.4) ng/L, respectively. And the IL-8 levels were (35.3±33.3), (4.8±1.7), (9.7±3.3) and (15.6±9.6) ng/L. In experimental group the IL-6 and IL-8 levels were significantly higher than those in control groups 1, 2, and 3 (P<0.01). In control group 2 and 3 the IL-6 and IL-8 levels were significantly higher than that in control group 1 (P< 0.01). Conclusions: The IL-6 and IL-8 levels of experimental group were significantly increased. IL-6 and IL-8 may be associated with the development of periodontal disease and AECOPD closely.

The expression of OCT4 and its clinical significance in laryngeal squamous carcinoma tissues.

OBJECTIVE: To investigate the expression of OCT4 and its clinical significance in laryngeal squamous carcinoma tissues. PATIENTS AND METHODS: Immunohistochemical staining was used to analyze the expression of OCT4 in 61 cases of laryngeal squamous carcinoma and 10 cases of the adjacent normal laryngeal tissues. RESULTS: The expression of OCT4 was not detected in normal laryngeal tissues, but could be detected in the nucleus of laryngeal carcinoma. The positive expression rates of OCT4 in well-moderately differentiated and poorly differentiated laryngeal squamous carcinoma tissues were 25.6% (11/43) and 66.7% (12/18) respectively, and there were significant differences (p < 0.01). The expression of the OCT4 protein was related to lymph node metastasis and TNM stage (p < 0.05), but not to gender, age and position of the tumor (p > 0.05). CONCLUSIONS: OCT4 is expressed in laryngeal squamous carcinoma tissues and is closely related to the cell differentiation of laryngeal carcinoma, lymph node metastasis and clinical stage.
