BackgroundPrevious studies have found that patients with generalized anxiety disorder （GAD） have impaired performance in executive function， and group cognitive behavioral therapy （CBT） has been shown to be effective in alleviating negative affect in patients with GAD， while its efficacy on executive function remains unclear. ObjectiveTo explore the efficacy of group CBT on anxiety symptom and executive function in GAD patients， so as to provide references for the rehabilitation program for GAD. MethodsA total of 80 consecutive patients with GAD who were hospitalized in Sleep and Psychosomatic Medical Center of Shiyan Taihe Hospital from March 2021 to August 2022 and met the Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5） diagnostic criteria for GAD were enrolled， and they were assigned into study group （n=40） and control group （n=40） using random number table methods. All patients were subjected to routine medication treatment and regular health education， based on this， study group received group CBT once a week （6 weeks， 60 to 90 minutes per session）. At the enrollment and after 6 weeks of treatment， patients were assessed using Hamilton Anxiety Scale （HAMA） and Frontal Assessment Battery （FAB）. ResultsANOVA with repeated measures on HAMA score revealed a significant time effect （F=1 870.320， P<0.01）， no significant group effect and no significant time×group interaction effect （F=1.254， 0.293， P>0.05）. Significant time effect， group effect and time×group interaction effect were reported on FAB scores （F=311.190， 4.399， 7.021， P<0.05 or 0.01）. Further analysis indicated that FAB scores of both groups after treatment were higher than those at baseline （t=200.569， 115.401， P<0.01）.And the FAB score of study group was higher than that of control group after treatment （t=-3.211， P<0.01）. ConclusionGroup CBT combined with medication treatment for GAD may alleviate the anxiety symptoms and improve executive function in GAD patients. ［Funded by Shiyan Science and Technology Bureau Pilot Scientific Research Project （number， 21Y21）］

OBJECTIVE To investigate the effect and mechanism of gracillin from Reineckia carnea on autophagy in non- small cell lung cancer A549 cells. METHODS Using A549 cells as subjects， the effects of different concentrations of gracillin （0.25， 0.5， 1， 2， 4 μmol/L） on the proliferation of cells were detected by CCK-8 after being treated for different time （12， 24， 48 h）. Compared with the control group without medication， the effect of gracillin （2 μmol/L） on the formation of autophagosomes in cells was observed by transmission electron microscope after 24 h of exposure. The aggregation of GFP-LC3 on autophagosome membrane was detected by GFP-LC3 plasmid transfection after being treated with gracillin （0.25， 0.5， 1， 2 μmol/L） for 24 h. Quantitative real-time PCR and Western blot assay were used to detect the mRNA and protein expressions of family with sequence similarity 102 member A（FAM102A）， the expressions of autophagy-related proteins [p62， Beclin-1， microtubule-associated protein 1 light chain 3B （LC3B）]， and the expressions of phosphoinositide 3-kinase （PI3K）/protein kinase B （Akt） signaling pathway-related proteins in A549 cells after being treated with gracillin （0.25， 0.5， 1 and 2 μmol/L） for 24 h. RESULTS Gracillin significantly inhibited the proliferation of A549 cells in a concentration- and time-dependent manner. The IC50 was 2.55 μmol/L at 24 h. After 24 h of gracillin treatment， autophagosomes with bilayer membrane structure were found in the cell cytoplasm， and GFP-LC3 green fluorescent spots on autophagosome membrane were obvious， representing an increasing trend as drug concentration. Compared with the control group， mRNA and protein expressions of FAM102A （0.5， 1， 2 μmol/L groups）， protein expression of Beclin-1 （1， 2 μmol/L groups） and LC3B-Ⅱ/LC3B-Ⅰ ratio （2 μmol/L group） were significantly increased in different concentrations of gracillin groups， while the protein expression of p62 （1， 2 μmol/L groups）， and the protein phosphorylations of Akt （1， 2 μmol/L groups） and PI3K （2 μmol/L group） were all decreased significantly （P＜0.05 or P＜0.01）. CONCLUSIONS Gracillin can promote excessive autophagy in A549 cells by up-regulating mRNA and protein expressions of FAM102A and inhibiting PI3K/Akt signaling pathway， thus inhibiting cell proliferation.

Objective To analyze the clinical manifestations and epidemiological characteristics of influenza in Hubei. Methods Pharyngeal swab specimens from 16,500 patients with suspected influenza infection admitted to our hospital from January 2020 to December 2022 were selected. Viral detection and serotyping were performed by fluorescence quantitative polymerase chain reaction. Furthermore, the epidemiological and clinical data of patients were collected to analyze the clinical features and epidemiological characteristics of influenza viruses.

MethodsA randomised， double-blind， placebo-controlled， multicentre study design was used to enroll 170 patients of SAP from nine centres， which were divided into 85 patients each in the trial group and control group with 1∶1 ratio. Both groups maintained the original western medicine treatment plan， and added Jiuxin Pill or placebo respectively， 2 pills （0.05 g） each time twicely for 28 days. The main outcomes were total exercise time （TED） in the exercise treadmill test and Seattle Angina Questionnaire （SAQ） scores including physical limitation （PL）， angina stability （AS）， angina frequency （AF）， treatment satisfaction （TS）， and disease perception （DP）. The secondary outcomes were exercise treadmill test indicators including heart rate recovery in 1 min （HRR1）， metabolic equivalents （METs）， maximum magnitude of ST-segment depression， and the Borg rating of perceived exertion scale， the average number of angina attacks per week， withdrawal and reduction rate of nitroglycerin， traditional Chinese medicine syndrome scores， incidence of major adverse cardiovascular events. Safety indicators were evaluated and the occurrence of adverse events during the trial was recorded. Data was collected before treatment， day 28±2 in treatment period， and follow-up at day 56 which is 28±2 days after treatment period finished. ResultsEighty-four and eighty-five patients respectively from trial group and control group were included to the full analysis set （FAS） and safety analysis set （SS）. Compared with the group before treatment and with the control group after treatment， the trial group had higher TED， HRR1， and METs， and lower maximum magnitude of ST-segment depression and Borg rating of perceived exertion scores after treatment （P＜0.01）. Compared with the group before treatment and with the control group after treatment and at follow-up， the total SAQ score and scores of AS， AF， TS and DP of the trial group after treatment and at follow-up elevated， while the average number of angina attacks per week and traditional Chinese medicine syndrome scores reduced （P＜0.01）. There was no statistically significant difference in the withdrawal and reduction rate of nitroglycerin between groups （P＞0.05）. Major adverse cardiovascular events occurred in 1 case （1/84， 1.19%） in the trial group and 1 case （1/85， 1.18%） in the control group， and the difference between groups was not statistically significant （P＞0.05）. A total of 3 cases of adverse events occurred in the trial group （3/84， 3.57%）， and a total of 6 cases of adverse events occurred in the control group （6/85， 7.06%）， and there was no statistically significant difference in the incidence of adverse events between groups （P＞0.05）. ConclusionIn the treatment of SAP， Jiuxin Pill combined with conventional western medicine can further enhance exercise tolerance， improve quality of life， and demonstrate great safety.

Objective: To explore the changing characteristics of Wnt2/β⁃catenin pathway in liver regeneration and repair in C57BL/6 mice. Methods : Male C57BL/6 mice were randomly divided into a sham⁃operated group (Sham group) , 1 d post⁃operative group , 2 d post⁃operative group , 4 d post⁃operative group , 6 d post⁃operative group , and 8 d post⁃operative group. Mice in the operated group underwent partial hepatectomy ( PHx) to remove the left and middle lobes of the liver, respectively. Plasma and liver tissues were collected on postoperative days 1 , 2 ,4 ,6 , and 8 , and plasma ALT and AST activity was measured by ALT(alanine aminotransferase) and AST( aspartate aminotransferase) biochemical analysis kits; Ki67 ⁃positive cells were identified by immunohistochemistry in each group;the number of HNF4⁃α and Ki67 double positive cells , the number of LYVE1 and Ki67 double positive cells , and the number of β ⁃catenin transferred into the nucleus were determined by immunofluorescence method. The expression of Wnt2 protein in each group was detected by Western blot , and the time characteristics of its expression during liver regeneration were analyzed. Results: Liver weight and liver/body weight ratio peaked on day 6 after PHx and approached the level of the Sham group. After PHx , there was severe liver damage on day 1 , but it had normalized by day 4. On day 2 after PHx , mainly hepatocytes proliferated;and on days 4 and 6 , mainly liver sinusoidal endothelial cells proliferated ,while the Wnt2/β⁃catenin pathway was activated. Conclusion The liver has a powerful regenerative repair ability ,which is closely related to the rapid proliferation of hepatocytes and liver sinusoidal endothelial cells , and the activation of the Wnt2/β⁃catenin pathway is activated in the regenerative repair of the mouse liver.

Autologous ozonized blood transfusion(AOBT) is a therapy of re-transfusion of 100-200 mL of autologous blood after shaking and agitation with appropriate amount of oxygen-ozone in vitro. The oxidation of blood through the strong oxidation of ozone can enhance the non-specific immune response of the body, regulate the internal environment and promote health. This therapy has been increasingly applied in clinical practice, while no unified standard for the operation process in terms of ozone concentration, treatment frequency and treatment course had been established. This operation process of AOBT is primarily explored in order to standardize the operation process and ensure its safety and efficacy.

Penetrating head injury is a serious open cranial injury. In civilians, it is often caused by non-missile, low velocity flying objects that penetrate the skull through a weak cranial structure, forming intracranial foreign bodies. The intracranial foreign body can be displaced due to its special quality, shape, and location. In this paper, we report a rare case of right-to-left displacement of an airgun lead bullet after transorbital entry into the skull complicated by posttraumatic epilepsy, as a reminder to colleagues that intracranial metal foreign bodies maybe displaced intraoperatively. In addition, we have found that the presence of intracranial metallic foreign bodies may be a factor for the posttraumatic epilepsy, and their timely removal appears to be beneficial for epilepsy control.

10,11-Dehydrocurvularin (DCV) is a natural-product macrolide that has been shown to exert anti-inflammatory activity. However, the underlying mechanism of its anti-inflammatory activity remains poorly understood. Aberrant activation of the NLRP3 inflammasome is involved in diverse inflammation-related diseases, which should be controlled. The results showed that DCV specifically inhibited the activation of the NLRP3 inflammasome in association with reduced IL-1β secretion and caspase-1 activation, without effect on the NLRC4 and AIM2 inflammasomes. Furthermore, DCV disturbed the interaction between NEK7 and NLRP3, resulting in the inhibition of NLRP3 inflammasome activation. The C=C double bond of DCV was required for the NLRP3 inflammasome inhibition induced by DCV. Importantly, DCV ameliorated inflammation in vivo through inhibiting the NLRP3 inflammasome. Taken together, our study reveals a novel mechanism by which DCV suppresses inflammation, which indicates the potential role of DCV in NLRP3 inflammasome-driven inflammatory disorders.

Objective: Compare and analyze the results of the domestic Lanyi AH600 glycated hemoglobin analyzer and other different detection systems to understand the comparability of the detection results of different detectors, and establish the best cut point of Lanyi AH600 determination of haemoglobin A1c (HbA1c) in the diagnosis of diabetes. Methods: Multi center cohort study was adopted. The clinical laboratory departments of 18 medical institutions independently collected test samples from their respective hospitals from March to April 2022, and independently completed comparative analysis of the evaluated instrument (Lanyi AH600) and the reference instrument HbA1c. The reference instruments include four different brands of glycosylated hemoglobin meters, including Arkray, Bio-Rad, DOSOH, and Huizhong. Scatter plot was used to calculate the correlation between the results of different detection systems, and the regression equation was calculated. The consistency analysis between the results of different detection systems was evaluated by Bland Altman method. Consistency judgment principles: (1) When the 95% limits of agreement (95% LoA) of the measurement difference was within 0.4% HbA1c and the measurement score was≥80 points, the comparison consistency was good; (2) When the measurement difference of 95% LoA exceeded 0.4% HbA1c, and the measurement score was≥80 points, the comparison consistency was relatively good; (3) The measurement score was less than 80 points, the comparison consistency was poor. The difference between the results of different detection systems was tested by paired sample T test or Wilcoxon paired sign rank sum test; The best cut-off point of diabetes was analyzed by receiver operating characteristic curve (ROC). Results: The correlation coefficient R² of results between Lanyi AH600 and the reference instrument in 16 hospitals is≥0.99; The Bland Altman consistency analysis showed that the difference of 95% LoA in Nanjing Maternity and Child Health Care Hospital in Jiangsu Province (reference instrument: Arkray HA8180) was -0.486%-0.325%, and the measurement score was 94.6 points (473/500); The difference of 95% LoA in the Tibetan Traditional Medical Hospital of TAR (reference instrument: Bio-Rad Variant II) was -0.727%-0.612%, and the measurement score was 89.8 points; The difference of 95% LoA in the People's Hospital of Chongqing Liang Jiang New Area (reference instrument: Huizhong MQ-2000PT) was -0.231%-0.461%, and the measurement score was 96.6 points; The difference of 95% LoA in the Taihe Hospital of traditional Chinese Medicine in Anhui Province (reference instrument: Huizhong MQ-2000PT) was -0.469%-0.479%, and the measurement score was 91.9 points. The other 14 hospitals, Lanyi AH600, were compared with 4 reference instrument brands, the difference of 95% LoA was less than 0.4% HbA1c, and the scores were all greater than 95 points. The results of paired sample T test or Wilcoxon paired sign rank sum test showed that there was no statistically significant difference between Lanyi AH600 and the reference instrument Arkray HA8180 (Z=1.665,P=0.096), with no statistical difference. The mean difference between the measured values of the two instruments was 0.004%. The comparison data of Lanyi AH600 and the reference instrument of all other institutions had significant differences (all P<0.001), however, it was necessary to consider whether it was within the clinical acceptable range in combination with the results of the Bland-Altman consistency analysis. The ROC curve of HbA1c detected by Lanyi AH600 in 985 patients with diabetes and 3 423 patients with non-diabetes was analyzed, the area under curve (AUC) was 0.877, the standard error was 0.007, and the 95% confidence interval 95%CI was (0.864, 0.891), which was statistically significant (P<0.001). The maximum value of Youden index was 0.634, and the corresponding HbA1c cut point was 6.235%. The sensitivity and specificity of diabetes diagnosis were 76.2% and 87.2%, respectively. Conclusion: Among the hospitals and instruments currently included in this study, among these four hospitals included Nanjing Maternity and Child Health Care Hospital in Jiangsu Province (reference instrument: Arkray HA8180), Tibetan Traditional Medical Hospital of TAR (reference instrument: Bio-Rad Variant Ⅱ), the People's Hospital of Chongqing Liang Jiang New Area (reference instrument: Huizhong MQ-2000PT), and the Taihe Hospital of traditional Chinese Medicine in Anhui Province (reference instrument: Huizhong MQ-2000PT), the comparison between Lanyi AH600 and the reference instruments showed relatively good consistency, while the other 14 hospitals involved four different brands of reference instruments: Arkray, Bio-Rad, DOSOH, and Huizhong, Lanyi AH600 had good consistency with its comparison. The best cut point of the domestic Lanyi AH600 for detecting HbA1c in the diagnosis of diabetes is 6.235%.
