Objective:To investigate the association of Subclinical Carotid AtheroSclerosis (SCAS) and prediabetes or Diabetes Mellitus (DM)in the healthy people.Methods:From September 2018 to June 2019, participants who underwent physical examination in the Health Management Center of Beijing Tiantan Hospitial were enrolled consecutively. The baseline characters were collected prospectively. Carotid Ultrasound was evaluated by radiologists according to the standard operating protocol. Univariable analysis and multivariable logistic analysis were used to estimate the association of prediabetes or DM with SCAS.Results:Totally 401 participants were eligible and enrolled. The mean age was (52.2±10.4) years and 43.7% (252/401) of them were females. The prevalence of DM and SCAS were 16.4% (66/401) and 48.9% (196/401) respectively. In the univariate analysis, elder age (≥60 years old) ( OR=5.93, 95% CI: 3.86-9.09, P<0.001), hypertension ( OR=2.76, 95% CI: 1.84-4.15, P<0.01), prediabetes( OR=1.67, 95% CI: 1.08-2.58, P<0.05) and DM ( OR=3.60, 95% CI: 1.97-6.58, P<0.01), cigarettes smoking ( OR=2.64, 95% CI: 1.82-3.81, P<0.001), lower HDLlevel<1.04 mmol/L ( OR=1.58, 95% CI: 1.04-2.42, P<0.001) and hyperhomocysteinemia (≥15 μmol/L)( OR=1.69, 95% CI: 1.17-4.04, P<0.01) were associated with higher prevalence of SCAS. On the contrary, female sex ( OR=0.53, 95% CI: 0.39-0.74, P<0.001) was associated with lower prevalence of SCAS. In the multivariable logistic analysis, elder age(≥60 years old) ( OR=6.04, 95% CI: 3.13-11.7, P<0.01), hypertension ( OR=2.14, 95% CI: 1.13-3.87, P<0.05), cigarettes smoking ( OR=2.19, 95% CI: 1.21-3.98, P<0.05) and DM ( OR=2.32, 95% CI: 1.16-4.67, P<0.05) were associated with SCAS independently. The association between prediabetes and SCAS was not statistically significant. Conclusions:DM is independently associated with SCAS in neurological healthy people, while prediabetes tended to increase the risk of SCAS.

Abstract: Objective To analysis the genetic evolution characteristics of hemagglutinin (HA) gene of influenza A(H1N1)pdm virus in Changsha City from 2016-2023, to understand the trend of the HA genetic evolution and the mutations of the amino acid. It provides a scientific basis for the prevention and control of influenza epidemics, as well as the screening of vaccines under the new situation. Methods The A(H1N1)pdm09 virus strains from Changsha City from 2016 to 2023 were isolated using SPF chicken embryos, and then the HA genes were sequenced by MiSeq of Illumina Inc. The homology of HA gene was analyzed by MegAlign of the DNASTAR, and the phylogenetic tree was constructed using the Neighbor Joining (NJ) method in the Molecular Evolutionary Genetics Analysis version 11 (MEGA11). Results The homology of the HA gene of A(H1N1)pdm virus in Changsha from 2016 to 2023 was between 94.8%-99.9%, with the HA gene homology decreasing annually. The homology between the isolated strains of A(H1N1)pdm09 in Changsha City from 2016 to 2023 and the WHO recommended vaccine strain ranged from 96.8% to 99.0%, indicating a relatively good match between the flu isolates and the recommended vaccine strain. The phylogenetic tree of the HA gene of the A(H1N1)pdm09 influenza virus in Changsha City showed that the HA gene evolved into several different branches within the 6B branch, and it had currently evolved to 6B.1A.5a.2a branch. Constant mutations had occurred at the amino acid sites of the four antigenic determinant clusters of HA protein. Currently, amino acid mutations had occurred at 15 antigenic sites within the four antigenic determinant clusters, and the newly emerged A186T antigen mutant site in the isolates from 2023 was worth recent notice. The receptor-binding sites are relatively conserved in loop 130, minor amino acid mutations occurred in loop 220, whether the amino acid mutation site in loop 190 is becoming more stable needs to be further monitored. Taking A/California/07/2009 (CY121680) as the reference strain, most of the A(H1N1) pdm09 isolates in Changsha was increased 162 NQTY glycosylation site and was decreased 276 NTTC glycosylation site, and the glycosylation mutations at these two sites have become more stable recently. Conclusions The HA genes of influenza A(H1N1)pdm virus in Changsha are constantly evolving and mutating, suggesting influenza surveillance should be strengthened continuously.

Objective:To explore the curative effect of laparoscopic surgery for hepatic cysticercosis.Methods:Search the literature from February 2010 to February 2020 on literature platforms such as Wanfang Data, VIP, CNKI, Pubmed, ScienceDirect, Web of Science, etc. the key words were "肝囊型包虫病" , "细粒棘球蚴" , "手术" , "开腹手术" , "腹腔镜" , "微创手术" , " echinococcosis " , " liver or hepatic " , " laparoscopic or minimal invasive " . Data on intraoperative indicators (e.g., operation time, bleeding volume), postoperative complications, hospital stay, recurrence rate, etc. in the literature included in the study were extracted and meta-analyzed.Results:A total of 9 articles were included, including 2 prospective studies and 7 retrospective case-control studies. A total of 1031 patients were enrolled, including 272 in the laparoscopic group and 759 in the laparotomy group. The results of the meta-analysis showed that the total postoperative complication rate in the laparoscopic group was lower than that in the laparotomy group ( OR=1.64, 95% CI: 1.10-2.45, P<0.05). Incision-related complications in the laparoscopy group and laparotomy group the difference was statistically significant ( OR=2.81, 95% CI: 1.03-7.70, P<0.05), and the hospital stay in the laparoscopic group was shorter ( SMD=1.21, 95% CI: 0.47-1.96, P<0.05). There was no significant difference between the two groups in operation time, postoperative bile leakage, residual cavity infection and effusion, and postoperative recurrence rate ( P>0.05). Conclusions:Under the premise of strictly grasping the indication of laparoscopic surgery, the incidence of complications after laparoscopic surgery is low, the hospitalization time is short.

OBJECTIVETo explore the immune response of silicotic rats to sheep red blood cells(SRBC).
METHODSSilicotic rats were immunized with SRBC by tracheal instillation(Group 1) or intraperitoneal injection (Group 2), and non-silicotic rats were immunized by tracheal instillation as normal control(Group 3). The levels of serum hemolytic index(HC50) were measured on 7, 12, 20, 25, and 32 days after primary immunization and 5, 12, 15 days after the second immunization. Special anti-SRBC IgG was measured with ELISA(A490 nm) on 12, 20, 25, 32 days and 5, 12, 15, 27 days respectively. Delayed-type hypersensitivity(DTH) to SRBC was measured 20 days after second immunization and DTH reaction was determined at 24, 48, 72, and 96 h after administration. Total cell count and cell populations in the bronchoalveolar lavage fluid(BALF), lung associated lymph node(LALN) and spleen weight, special IgG secreted from spleen cells were measured at the end of the experiment.
RESULTSThe HC50 of Group 1(47.4 +/- 1.0, 52.2 +/- 4.6, 31.1 +/- 11.9, 43.8 +/- 3.5, 33.6 +/- 16.8, 49.0 +/- 2.3, 92.9 +/- 20.2, 87.7 +/- 5.2) were statistically higher than those of Group 3(40.4 +/- 10.6, 2.8 +/- 2.5, 0.8 +/- 0.6, 6.6 +/- 5.8, 1.4 +/- 0.1, 36.5 +/- 16.5, 53.0 +/- 33.2, 2.6 +/- 2.2). The special anti-SRBC IgG response in Group 1(1.67 +/- 0.19, 1.98 +/- 0.36, 1.12 +/- 0.50, 1.38 +/- 0.30, 2.75 +/- 0.15, 2.60 +/- 0.28, 2.86 +/- 0.10, 2.50 +/- 0.20) were much stronger than those in Group 3 (0.59 +/- 0.30, 0.56 +/- 0.21, 0.21 +/- 0.16, 0.22 +/- 0.01, 0.81 +/- 0.25, 0.74 +/- 0.25, 0.69 +/- 0.26, 1.38 +/- 0.41). Furthermore, the results of DTH showed positive response and the ratios for diameter of skin rash > 5 mm at 24, 48, 72, 96 h were 16/16, 16/16, 16/16, 15/16 respectively in Group 1, while those in Group 3 were 8/15, 1/15, 1/15, 1/15 respectively. Total cell count in the BALF, LALN and spleen weight, and special IgG secreted from spleen cells in Group 1 were higher too. Group 2 expressed almost of the same but with mild immunologic responses as Group 1.
CONCLUSIONSilicosis-induced extremely strong DTH and over-response of humoral immunity to some antigens may contribute to the likelihood of silicosis complicated with tuberculosis.

Esophageal cancer is one of the most common malignant tumors in China and dysphagia caused by malignant stenosis is the most common symptom of advanced esophageal cancer. The inability to eat orally seriously affects the quality of life of patients with advanced esophageal cancer, and poor nutritional status caused by dysphagia limits the implementation of standard treatment programs such as radiotherapy and chemotherapy, resulting in a decline in survival. The 125I radioactive stent is a novel treatment for malignant stenosis. Studies have shown that it can relieve dysphagia and prolong patients' survival compared to traditional esophageal stents. In this article, the treatment of malignant stenosis in advanced esophageal cancer and the clinical application progress of 125I radioactive stents were reviewed.
