ABSTRACT
OBJECTIVE: To explore the functional role of the drug-dependent mesenchymal-epithelial transition (Met)-axiation "π" structural module of neurogenesis after processing by three components of Qingkailing injection in neurogenesis and angiogenesis in cerebral ischemia. METHODS: We used a Glutathione S-transferase (GST)-pull down assay, isothermal titration calorimetry assay, and other related methods to identify the relationships among Met, inositol polyphosphate phosphatase like 1 (Inppl1), and death associated protein kinase 3 (Dapk3) in this allosteric module. The biological effects of the modules of neurons generation composed of Met, Inppl1, and Dapk3 were measured through Western blot, apoptosis analysis, and double immunofluorescence labeling. RESULTS: The GST-pull down assay revealed that proline-serine-threonine rich domain of Met binds to the Src homology domain of Inppl1 to form a protein-protein complex; Dapk3 with a C-terminal domain interacts weakly with the protein kinase C domain of Met in the intracellular region. Thus, we obtained a "π" structuring module considered a neural regeneration module. The biological effects of angiogenesis and neurogenesis modules composed of Met, Inppl1, and Dapk3 were also verified. CONCLUSION: The study suggested that understanding the functional modules that contribute to pharmaceutics might provide novel signatures that can be used as endpoints to define disease processes under stroke or cerebral ischemia conditions.

Comprehensive quantitative assessment of China's urban industrial water use efficiency is effectively promote the green industrial development important steps in order to realize the overall development of high quality. Between 2009 and 2021, 290 in China based on ground level above the panel data of the city, this paper conducts research based on two principles of efficiency improvement and four models of efficiency analysis. The results show that: First, from the perspective of spatial differences, the integrated water use efficiency of urban industry in China presents a slow and uneven upward trend of "low in the east and high in the west, high in the middle and low in the north and south". Second, from the perspective of driving factors, population density and government public investment on the whole inhibit the development of this efficiency, while GDP development and technological innovation promote it. Third, from the perspective of dynamic evolution prediction, the phenomenon of "beggar-thy-neighbor" and "neighborly kindness" coexist. Therefore, the government should implement industrial water-saving measures according to local conditions, the society should improve the supervision of the behavior of wasting industrial water, and the enterprises should speed up the integration process of industrial primary and repeat water efficiency, so as to promote the comprehensive green transformation of the economy and society.
ABSTRACT
Objective:To explore the effect of chitosan hydrogel on the serum levels of tumor necrosis factor (TNF-α),interleukin (IL-10) and intercellular adhesion molecule (ICAM-1) of patients with burns.Methods:96 cases with second degree burns who were treated in our hospital from June 2015 to November 2016 were selected and randomly divided into two groups,with 48 cases in each group.The patients in the observation group were treated with chitosan hydrogel,while the patients in the control group were treated with conventional vaseline gauze wound.Then the wound healing,the serum levels of tumor necrosis factor (TNF-α),interleukin (IL-10) and intercellular adhesion molecule (ICAM-1) and the incidence of adverse reactions were observed and compared between the two groups before and after the treatment.Results:The healing rate of superficial burns at the 7th day in the observation group was significantly higher than that of the control group (P＜0.01).The healing rate of deep burns at the 15th day and 25th day were significantly higher than those of the control group (P＜0.05).The healing time of the superficial burns and deep bums in the observation group were significantly shorter than those of the control group,and the SI score was significantly lower (P＜0.01).After treatment,the serum levels of TNF-α,IL-10 and ICAM-1 of patients with superficial burns significantly decreased in the two groups,and the observation group was lower than that of the control group (P＜0.05).The serum levels of TNF-α,IL-10 and ICAM-1 of patients with deep burns were significantly lower than before,and the observation group was lower than that of the control group (P＜0.01).The incidence of wound infection in the observation group was lower than that of the control group (P＜0.05).Conclusion:Chitosan wound repair membrane gel could accelerate the wound healing,prevent the wound infection,and reduce the inflammation with high safety.
ABSTRACT
Objective To summarize analysis in elderly patients with type 2 diabetes mellitus with cerebral microvascular lesion with diabetes pill in combination with metformin on patients after treatment the blood viscosity, the effects of cognitive dysfunction.Methods Our hospital during the period of July 2014 to September 2016 received 100 cases of elderly patients with type 2 diabetes mellitus with cerebral microvascular lesions, according to the random allocation method divided into observation group(50 cases) and control group(50 cases) and control group using metformin treatment, the observation group USES the diabetes pill metformin treatment, treatment effect of two groups of patients and related indicators for comparative analysis.Results After treatment the cognitive function score and blood viscosity related indicators, statistically significant differences between observation group and control group.Conclusion Elderly patients with type 2 diabetes mellitus with cerebral microvascular lesions in clinical application in diabetes, pill metformin, help to improve the patient's cognitive dysfunction, improve the patient's blood viscosity, promote the prognosis of patients, is worthy of popularization and application.
ABSTRACT
<p><b>OBJECTIVE</b>To observe the curative effects of platelet-rich plasma (PRP) combined with negative-pressure wound therapy (NPWT) on patients with sternal osteomyelitis and sinus tract after thoracotomy.</p><p><b>METHODS</b>Sixty-two patients with sternal osteomyelitis and sinus tract after thoracotomy, hospitalized from March 2011 to June 2015, were retrospectively analyzed. Based on whether receiving PRP or not, patients were divided into two groups, group NPWT ( 22 patients hospitalized from March 2011 to December 2012) and combination treatment group (CT, 40 patients hospitalized from January 2013 to June 2015). After debridement, patients in group NPWT were treated with continuous NPWT (negative pressure values from -15.96 to -13.30 kPa), while those in group CT were treated with PRP gel (blood platelet counts in PRP ranged from 1 450×10(9)/L to 1 800×10(9)/L, with 10-15 mL in each dosage) made on the surgery day to fill the sinus tract and wound, followed by NPWT. Negative pressure materials were changed every 5 days until 20 days after surgery in patients of both groups. PRP gel was replenished before changing of negative pressure materials in patients of group CT. The sinus tract sealing time, wound healing time, number of patients who had secondary repair surgery, number of patients who had recurrence of sinus tract within three months after wound healing, and length of hospital stay were recorded. Data were processed with t test, Fisher's exact test, and chi-square test.</p><p><b>RESULTS</b>The sinus tract sealing time, wound healing time, and length of hospital stay in patients of group CT were (16±8), (27±13), and (43±13) d respectively, which were all significantly shorter than those in group NPWT [(29±14), (41±17), and (60±20) d, with t values from 3.88 to 4.67, P values below 0.01]. The number of patients who had secondary repair surgery in group CT was less than that in group NPWT (P<0.01). There was no statistically significant difference in the number of patients who had recurrence of sinus tract between two groups (P>0.05).</p><p><b>CONCLUSIONS</b>Compared with NPWT only, PRP combined with NPWT has great curative effects on patients with sternal osteomyelitis and sinus tract after thoracotomy, for it shortens sinus tract sealing time, wound healing time, and length of hospital stay, and avoids the secondary repair surgery. This method is simple and safe with little injury.</p>
