OBJECTIVETo investigate the injury stress responses caused by ischemia reperfusion and its effects on the salivary secretory function of rat submandibular glands.
METHODSAn in situ ischemia reperfusion experimental model of rat submandibular glands was developed. The rat submandibular glands were subjected to 90 min of ischemia without denervation followed by reperfusion for 1, 12, 24, and 72 h. Salivary secretion, histological changes, reactive oxygen species (ROS) levels, and cellular apoptosis of the involved submandibular glands were detected after reperfusion.
RESULTSThe secretory function of the glands decreased at 1 and 12 h, and the saliva secretion gradually had the same value as that of the control sample 72 h after reperfusion. Increasing inflammatory cells infiltration, cellular atrophy, and tissue edema were observed especially after reperfusion for 12 h. The level of ROS and the number of apoptotic cells exhibited the same tendency, and higher ROS levels and more apoptosis cells 1 and 12 h after reperfusion were observed.
CONCLUSIONOur study suggests that ischemia reperfusion can cause a series of injury stress responses in submandibular glands, which might have an important function in the early phase dysfunction of transplanted submandibular glands.

Objective: To provide an efficeut protocol for constructing recombinant adenovirus, an in vitro ligation was used instead of homologous recombination. Methods: Gene BMP-2 was ligated into pShuttle 2 vector ( pShuttle 2-BMP-2 ) and then fragment containing BMP-2 gene and promoter pcmvie excised by PI-SCe Ⅰ and Ⅰ-Ceu Ⅰ endonuclease. The fragment was further combined with adenovirus vector (Adeno-X-BMP-2) , which was finally linearized with Pac Ⅰ and trans-fered to HEK293 to package adenovirus particles. Results: Both PCR assay and restiction analysis showed that the recombined rectors pShuttle2-BMP-2 and Adeno-X-BMP-2 contains the target BMP-2 gene. THe packaged adenovirus was also i-dentified by PCR assay with specific primers for BMP-2. Conclusions: The BMP-2 incorporated recombinant adenovirus was obtained and this laid a foundation for further study on BMP-2 mediated gene therapy. The in vitro ligation method de-scinbed here for constructing recombined adenovirus was more efficient than traditional homologous recombination.

The seamless phase Ⅱ/Ⅲ design integrates independent phase Ⅱ and phase Ⅲ clinical trials into a continuous, phased adaptive clinical trial design. Compared with traditional independent phase Ⅱ and phase Ⅲ clinical trials, the seamless design offers significant advantages in accelerating drug or vaccine development and improving clinical trial efficiency. Currently, the application of this design in anti-tumor drug research is becoming increasingly mature, and it is gradually expanding to clinical trials of vaccines, including the 9-valent human papillomavirus vaccine, sabin strain inactivated polio vaccine, and others. This paper aims to clarify the seamless phase Ⅱ/Ⅲ design concept and offer valuable insights into its implementation. It accomplishes this by presenting a clinical trial example featuring a phase Ⅱ/Ⅲ seamless design for a 9-valent human papillomavirus vaccine. The article delves into the specific considerations and potential challenges related to implementing the seamless design, aiming to provide valuable insights for optimizing vaccine clinical trials within our country.

Objective To investigate the expressions of CD28 and CD117 in patients with newly diagnosed multiple myeloma (MM) and their clinical significances. Methods The clinical data of 115 newly diagnosed MM patients in the First Affiliated Hospital of Zhengzhou University from May 2015 to December 2017 were retrospectively analyzed. The expressions of CD28 and CD117 were detected by using multiparameter flow cytometry. The relationship between the expressions of CD28 and CD117 and MM staging and clinical parameters was analyzed. The staging was performed according to the International Staging System (ISS). Results Among these 115 patients, there were 15 patients with CD117 positive and 30 patients with CD28 positive. Erythrocyte sedimentation rate (r = -0.481, P = 0.039), Cˉreactive protein level (r = -0.314, P=0.015), the proportion of plasma cells detected by bone marrow cytology (r=-0.027, P=0.001) were negatively correlated with CD117 positive expressions. CD28 positive expression was positively correlated with lactate dehydrogenase level (r = 0.249, P = 0.033) and ISS stage (r = 0.319, P = 0.017), while it was negatively correlated with hemoglobin level (r = -0.372, P = 0.026). CD28 positive was associated with light chain type, and nonˉsecretory type mostly occurred (P = 0.016). The incidence of osteolytic lesions in CD28 positive group and CD117 positive group was high, but there was no statistical difference between CD28 positive group, CD117 positive group and CD28 negative group, CD117 negative group (P = 0.052, P=0.479). Conclusions The positive expression of CD117 in the early stage of MM patients is higher than that in the advanced stage, and the expression of CD28 positive in the advanced stage of MM patients is higher than that in the early stage. CD28 and CD117 can be used as indicators of prognosis stratification in the patients with newly diagnosed MM.
