RESUMEN
Objective To analyze the reasons of gastrointestinal function recovery related to postoperative esophagogastric fistula and the roles of the Xiaochengqi decoction by enema and jejunal nutrition tube on gastrointestinal function recovery.Method Clinical data of 1 patient with esophagogastric anastomotic fistula after gastric stromal tumors(GST)resection on March 16,2022 was retrospectively analyzed,to observe the influence of Traditional Chinese Medicine in postoperative recovery.Results The patient,a 77-year-old male,underwent laparoscopic proximal gastrectomy and esophagogastrostomy on March 16,2022 due to cardia tumor.Seven days after surgery,there was some turbid matter in the abdominal drain tube,severe pain on upper abdomindal occurred after digestive tract radiography,it was indicated that anastomotic fistula was existed.After intragastric administration and nasal feeding of Xiaochengqi decoction,anus ventilates and defecates much mushy stool on the 15th day after postoperative esophagogastric fistula.On the 21st day after fistula,Buzhongyiqi and Xiaochengqi decoction was applied by nasointestinal feeding tube.On the 47th day,the patient got out of bed and stood,the stools were out by enema.On the 58th day after surgery,the digestive tract radiography indicated there was not any contrast media overflow near the fistula and contrast media could get through the duodenum smoothly.Anastomotic stricture.After tube extraction,a liquid diet is fed,formed stool is defecated without abdominal distension and pain.On the 63rd day after surgery,the patient is discharged from hospital.Conclusions It is advantageous for the recovery of gastrointestinal function by enema and jejunal nutrition tube feeding of Xiaochengqi decoction.It shortens the anal exhaust time,fastens the recovery of gastrointestinal function,improves health status,promotes healing,and shortens the length of stay.
RESUMEN
Objective:To analyze the clinical characteristics and pathogenic distribution of severe pneumonia in adults in order to provide basis for clinical diagnosis and treatment.Methods:From June 2021 to April 2022, 145 patients with pneumonia admitted to the Department of Respiratory and Critical Care Medicine of the Second People's Hospital of Guangdong Province. According to whether they meet the diagnostic criteria for severe pneumonia, they were divided into severe ( n=63) and mild ( n=82) groups, and the clinical features between the two groups were compared. At the same time, the role of FilmArray detection in severe pneumonia was discussed. The measurement data were tested using independent sample t test or Mann-Whitney U test, and the counting data were tested using Chi-square test or Fisher exact probability method. Results:The age of the patients in the severe group was (72.67±1.71) years, male patients accounted for 84.1%, and the median hospitalization time was 16 days. Nine patients died in hospital; most of them had fever, shortness of breath, and change of consciousness, accompanied by hypertension, diabetes, cerebrovascular disease, chronic kidney disease, and tumor history. Compared with the mild group, the total number of leukocytes, neutrophil ratio, procalcitonin, and C-reactive protein were higher in the severe group, but the CD3 +, CD4 +, and CD8 + cell counts were lower ( P<0.05). The positive rate of FilmArray detection in the severe group was 81%, and the mixed infection of multiple bacteria accounted for 50%, which was higher than that of traditional culture ( P<0.05). The top four pathogens in severe group were Pseudomonas aeruginosa, Acinetobacter baumannii complex, Klebsiella pneumoniae, and Staphylococcus aureus, which were significantly higher than that in the mild group ( P<0.05). Resistance genes were detected in patients with severe disease, which was significantly higher than that in patients with mild disease (70.7% vs. 17.5%, P<0.05). Conclusions:Severe pneumonia is more common in elderly men, with more basic diseases and poor immunity. FilmArray has a high positive rate and can detect multiple pathogens, which may have a role in the rapid diagnosis of severe pneumonia.
RESUMEN
Objective To evaluate the feasibility of repair of full-thickness skin defects in nude mice with tissue-engineered skin which was constructed by culture of human amniotic epithelial cells (hAECs) and fibroblasts on human de-epidermized dermis (DED).Methods Healthy human amniotic tissues were treated with trypsin at a low concentration in multi-steps to prepare hAECs,and a two-step collagenase digestion was used to treat healthy children's prepuce tissues to prepare fibroblast suspensions.When fibroblasts were cultured in vitro up to passage 3-5 and hAECs up to passage 2,they were seeded on the reticular dermal surface and basement membrane surface of the DED respectively to construct the tissueengineered skin.A total of 20 heahhy male nude mice aged 3-4 weeks were enrolled into this experiment,and full-thickness skin defects were made on the middle of the back of mice.Then,these mice were randomly divided into 2 groups by using a lottery method,and reconstructed full-thickness tissueengineered skin grafts and vaseline oil gauze were used to cover the wounds in the tissue-engineered skin group and control group respectively.The whole body and transplantation sites of the nude mice were observed on day 7,14,21 and 28 after transplantation,the wound healing time and rate were compared between the above two groups,and skin tissues at the transplantation site were harvested at 4 weeks after transplantation and subjected to histological examination.Results HAECs had stem-cell characteristics and expressed octamer-binding protein-4 (OCT-4) and embryonic marker stage-specific embryonic antigen4 (SSEA-4).After 2-week organ culture,the in vitro reconstructed tissue-engineered skin showed 4-9 continuous layers of stratified epithelium,and the histological structure of the epidermis was similar to that of the normal human skin.Compared with the control group,the tissue-engineered skin group showed significantly higher wound healing rates on day 7,14 and 21 after transplantation (57.49％ ± 6.11％ vs.22.93％ ± 4.26％,92.80％ ± 3.10％ vs.54.57％ ± 7.94％,98.83％ ± 0.25％ vs.91.16％ ± 4.79％,respectively;n =10,t =27.36,32.23,11.80,respectively,all P ＜ 0.001),shorter wound healing time [(21.51 ± 1.51) d vs.(28.80 ± 1.14) d,n =10,t =42.23,P ＜ 0.001],with the color of skin grafts closer to that of autologous skin on day 28 after transplantation.Histological examination revealed distinct stratification of the epithelium,obvious keratinization and favorable growth of cells in the dermis in the tissue-engineered skin group,but thin epithelium with some defects,indistinct stratification of the dermis,and inflammatory cell infiltration in the control group.Condusion Tissue-engineered skin constructed by the culture of hAECs and fibroblasts on human DED can survive in nude mice after transplantation,resulting in a more favorable healing of wounds,and is expected to serve as a kind of ideal tissue-engineered skin.
RESUMEN
<b>Background and Objective</b><BR> The prevalence of non-communicable diseases (NCD) is increasing in low- and middle-income countries, imposing major public health and development threats. However, there is difference among countries with regard to the patterns of NCD metabolic risk factors. This study aims to categorize the pattern of metabolic risk factors in East Asia, Southeast Asia and Oceania. <BR><b>Methods</b><BR> Age-standardized prevalence of obesity, raised blood pressure, raised blood glucose, and raised blood cholesterol for 2008 were obtained from the World Health Organization (WHO) Global Health Observatory Data Repository. We used hierarchical cluster analysis to categorize countries in East Asia, Southeast Asia and Oceania based on the prevalence of NCD metabolic risk factors of each country. <BR><b>Results</b><BR> Three patterns of NCD metabolic risk factors were identified. The first pattern showed relatively high prevalence of raised blood cholesterol, while prevalence of obesity, raised blood pressure and raised blood glucose remain relatively low. Most high- and upper-middle-income Asian countries were included in this pattern. The second pattern presented relatively high prevalence of raised blood pressure, although prevalence of obesity, raised blood glucose, and raised blood cholesterol stay relatively low. Most low- and lower-middle-income Asian countries were categorized in this pattern. The third pattern presented high prevalence of obesity and relatively high prevalence of raised blood pressure and raised blood glucose. This pattern included most Pacific island countries.<BR><b>Conclusions</b><BR> Policy makers in countries in East Asia, Southeast Asia, and Oceania should take into account for the features of the pattern they are in, when they set priorities for developing effective NCD control measures.
RESUMEN
This study examined the cytotoxicity of a new implant material modified by microarc oxidation technique. Cells on different surfaces of the implant were evaluated 2, 4 and 6 days after treatment. The results showed that cell attachment, cell morphology, and cell proliferation were influenced by the different surface treatments, and a significant increase in the osteoblast cell activity was observed on the porous MAO-Ti coating. Our results suggest that the porous MAO-Ti surface has a better biocompatibility and electrochemical performance than pure titanium surface.
