ABSTRACT
Objective:To establish a method of serum detection by Raman spectroscopy for the diagnosis of gastric cancer.Methods:Between April and November 2019, 110 patients with gastric cancer [73 males, 37 females, age (57.4±10.3) years] and 74 patients with colorectal cancer [48 males and 26 females, aged (58.3±12.2) years] were collected at the First Affiliated Hospital of Army Military Medical University, along with 100 healthy subjects [59 males and 41 females, aged (55.6±10.61) years] during the same period. Fasting venous blood serum samples were collected from the subjects. A Raman spectrometer XploRA PLUS was used in this experiment, with an excitation light source of 532 nm, a field of view of 100 times, and a spectrum range of 200-2 000 cm -1, etc. The serum samples were detected by nondestructive and non-contact rapid detection, and the Raman spectra of serum samples were collected. Using the Raman spectrum acquisition and processing supporting software LabSpec6 to smooth, baseline, and normalize the obtained Raman spectrum. Multivariate statistical analysis software SIMCA14.1 were applied to import and analyze the obtained Raman spectrum data by principal component analysis (PCA), orthogonal partial least squares discriminant analysis (OPLS-DA), and other methods for statistical analysis. An operating characteristic curve (ROC) was constructed to evaluate the model analysis effect between serum samples of healthy people and those with gastric cancer. Serum samples from the colorectal cancer group were used to verify the reliability of the model. Results:Six Raman peaks with good repeatability were detected in serum samples in health and gastric cancer group, and peaks were located at 1 001.17, 1 154.63, 1 337.89, 1 446.85, 1 515.33, and 1 658.34 cm -1, respectively. Raman intensities at six Raman peaks were significantly different between healthy and gastric cancer groups. At the displacement of 1 001.17, 1 154.63, and 1 515.33 cm -1, the Raman intensity in the healthy group was higher than that in the gastric cancer group. At 1 337.89, 1 446.85, and 1 658.34 cm -1 displacement, the Raman intensity of the gastric cancer group was higher than that of the healthy group. An OPLS-DA model was constructed to analyze the serum samples of the healthy group and the gastric cancer group. In the model, R 2 is the fitting power, and Q 2 is the predictive ability. The closer the values of R 2 and Q 2 are to 1, the better the performance of the model, and the obtained model's R 2X(cum)=0.809, R 2Y(cum)=0.819, Q 2(cum)=0.758. ROC characteristic curve was drawn based on the OPLS-DA model. The area under the curve (AUC) of the gastric cancer group was 0.998. Six peaks with good repeatability were detected in the serum Raman spectra of gastric cancer stage Ⅰ, Ⅱ, Ⅲ, and Ⅳ, which were located at the displacement of 1 001.85, 1 155.07, 1 338.36, 1 445.75, 1 515.92, and 1 657.68 cm -1, respectively, and at the displacement of 1 155.07 and 1 515.92 cm -1. The Raman intensity of gastric cancer stage Ⅳwas significantly higher than that of gastric cancer stages Ⅰ, Ⅱ, and Ⅲ. Conclusions:According to the model reliability verification, the healthy group, gastric cancer group and colorectal cancer group can also be effectively separated based on OPLS-DA results; it showed a good performance in separating the healthy group from the gastric cancer group. It is possible to detect serum samples from healthy people and gastric cancer patients unlabeled by combining Raman spectroscopy and the OPLS-DA method in multivariate statistics.

ABSTRACT
Objective To study the regulation of microRNA - 22(miR - 22)on glycometabolism of hemato-poietic stem cell TF - 1 and its molecular mechanism. Methods TF - 1 cells were cultured for 2 h under hypoxic con-ditions. The expression levels of Glut4 and miR - 22 was detected by quantitative real-time PCR(qRT - PCR). The sgRNA vector of the miR - 22 gene was constructed and miR - 22 gene of TK - 1 cells was knocked out by the CRISPR/ Cas9 technique. Overexpression vectors were constructed,and miR - 22 knocked - out cells were introduced to overexpress miR - 22,the expression of miR - 22 was detected by qRT - PCR and the expression levels of Glut4 and PPAR - γ were detected by qRT - PCR and Western blot. Results Compared with the control group,the expression of miR - 22 in TF - 1 cells decreased (0. 015 ± 0. 000 vs. 0. 056 ± 0. 001)and the expression of Glut4 (0. 351 ± 0. 038 vs. 0. 152 ± 0. 005)and PPAR - γ (0. 421 ± 0. 017 vs. 0. 248 ± 0. 008)increased,when TF - 1 cells were cultured for 2 h under hypoxic conditions,and the differences were statistically significant (all P < 0. 05). Compared with the control group,the expression levels of Glut4 (0. 019 ± 0. 00 vs. 0. 008 ± 0. 000)and PPAR - γ (0. 038 ± 0. 001 vs. 0. 019 ± 0. 000)were significantly increased after miR - 22 gene silencing,and they were significantly decreased (Glut4:0. 005 ± 0. 000 vs. 0. 008 ± 0. 000;PPAR - γ:0. 137 ± 0. 000 vs. 0. 019 ± 0. 000)after overexpression of miR - 22,and the differences were statistically significant (all P < 0. 05). Conclusions It suggests that miR - 22 ex-erts a negative regulation on glycometabolism of hematopoietic stem cell TF - 1 by downregulating the expression of PPAR - γ. A new regulatory factor of TF - 1 glycometabolism and the mechanisms are identified,which has provided new ideas for the targeted medication of diseases induced by hematopoietic stem cell dysfunction.

ABSTRACT
Objective To explore cell suspension and level of IL-17 in bronchoalveolar lavage fluid (BALF) of children with labor pneumonia combined with mycoplasma pneumonia and its clinical significance. Methods 87 children with labor pneumonia who had been done BAL were divided into CPIS ≥ 6 group and CPIS 0.05). The percentage of columnar epithelial cells in CPIS < 6 group were higher than CPIS ≥ 6, how-ever, macrophagocyte was lower ( < 0.05). The percentage of neutrophils are related with both MP-DNA ( = 0.48,= 0.000) and IL-17 ( =0.49, =0.000). Conclusions The composition of BALF is more appropriate to react the circumstance of lobar pneumonia. When lobar pneumonia occurs, columnar epithelial cells are damaged, macrophagocyte gathered to participate in the inflammatory response. In Mycoplasma pneumonia infection group, IL-17 raises neutrophils to resist infection, NE%in BALF can indirectly reflect the mycoplasma infection degree.
ABSTRACT
Objective To observe the behavioral and the histopathology changes and expression of NR2B subunit in spinal dorsal horn in chronic constriction injury (CCI) rats after pulsed radiofrequency (PRF). Methods Forty-eight adult Sprague-Dawley rats were randomly divided into Sham-Sham (SS), Sham-PRF (SP), CCI-Sham (CS) and CCI-PRF (CP) groups. The right sciatic nerves (SNs) of the CS and CP groups were ligated to create the CCI model. For the SS and SP groups, the right SNs were separated without ligation. The CP and SP groups accepted PRF at the ligation site 15 days after modeling, while the electrode was placed in rats in the SS and CS groups without elec-tricity. The hindpaw withdrawal threshold (HWT) was measured before and 3, 7, 11, 15 days after modeling, and 1, 3, 7, 11, 15 days after treatment. The right SNs at ligation sites were assessed with optical microscopic score 15 days after treatment, and the NR2B expression in the L4-6 spinal dorsal horn were determined with Western blotting. Results HWT was significantly shorter in the CS and CP groups than in the SS and SP groups after modeling, and was more in the CP group than in the CS group. Under the optical microscope, the axonal diame-ter and myelin sheath thickness increased in the CP group compared to those in the CS group (P<0.01), the NR2B expression was less in the CP group than in the CS group after treatment (F=10.769, P<0.05). Conclusion PRF may reduce hyperalgesia and repair damaged SNs in CCI-induced neuropathic pain, which may associate with inhibition of the NR2B subunit expression in spinal dorsal horn.
ABSTRACT
Objective To investigate the characteristics of postoperative complications and related risk factors in neurosurgery patients. Methods A retrospective study was carried out in neurosurgery patients during anesthesia recovery period from March, 2009 to November, 2013. The recorded complications included respiratory and circulatory system complications, pain, shivering, nausea and vomiting, agitation and delaying recovery. Multivariate logistic regression analysis was performed to screen the risk factors for these complications. Results Da-ta of 13,495 patients were available for analysis. The general incidence was 48.8%. Post-operative complications included post-operative nausea and vomiting (PONV) (14.5%), agitation (13.5%), hypertension (13.4%), arrhythmia (9.3%), shivering (8.9%), pain (5.9%), hypox-emia (2.5%), delayed recovery (1.9%), airway obstruction (1.7%) and hypotension (0.3%). Regression analysis showed that the risk factors for hypoxemia included male,<59 years old and infratentorial tumor (P<0.05);the risk factors for PONV included male, supratentorial tu-mor, infratentorial tumor, cerebrovascular disease, inhalation anesthesia, the use of muscle relaxants antagonism and tramadol (P<0.05);and the risk factors for postoperative restlessness included male, infratentorial tumor and cerebrovascular disease, inhalation anesthesia, the use of muscle relaxants antagonism and no use of patient-controlled analgesia (PCA) pump (P<0.05). Conclusion Patients with different neuro-logical diseases showed different post-operative complications and exhibited different risk factors for these complications. Anesthesiologists should closely monitor patients receiving various neurosurgery and provide timely treatment.
ABSTRACT
AIM:To investigate the effects of high plasma triglyceride (TG) caused by apolipoprotein C Ⅲ( ApoC Ⅲ) transgene on the occurrence and development of abdominal aortic aneurysm ( AAA) .METHODS:The animal models of hypercholesterolemia and hypercholesterolemia combined with hypertriglyceridemia were established by feeding high-fat diet to LDLR-/-and ApoC Ⅲ+LDLR-/-mice, respectively.AAA was induced in these mice by pancreatic elastase. By evaluating the incidence of AAA, relative maximal abdominal aortic diameter, disruption of the elastic lamellar structure and expression of matrix metalloproteinases ( MMPs) in the aorta walls of the AAA, the occurrence and development of AAA were compared in LDLR-/-and ApoC Ⅲ+LDLR-/-mice fed with either chow diet or high-fat diet.In addition, an in vitro TNF-α-induced aneurysmal microenvironment model on vascular smooth muscle cells ( VSMC) was used to study the impact of triglyceride-rich lipoproteins ( TRLs) from mice with normal or high contents of ApoCⅢon elastin protein expres-sion.RESULTS:Feeding the high-fat diet aggravated the severity of AAA in the LDLR-/-mice.ApoC Ⅲ+LDLR-/-mice fed with high-fat diet had less severe AAA than LDLR-/-mice fed with high-fat diet.TRLs inhibited degradation of VSMC elas-tin protein induced by TNF-α, and in vitro TRLs from the mice with high content of ApoC Ⅲ, compared to those with nor-mal content of ApoC Ⅲ, had better inhibitory effect on the degradation of elastin.CONCLUSION:High plasma TG caused by ApoC Ⅲtransgene alleviates AAA of the LDLR-/-mice induced by elastase and high-fat diet.The effect is probably attrib-uted to the hypertriglyceridemia caused by ApoC Ⅲtransgene.
