Objective To evaluate the effects of dexmedetomidine on the cellular immune function of the rats with scald.Methods Seventy-two healthy male Sprague-Dawley rats,weighing 200-220 g,aged 120-150 days,were randomly divided into 3 groups (n =24 each):normal control group (group C),scald group (group S) and dexmedetomidine group (group D).Thirty percent of the total body surface was shaved and then exposed to 94 ℃ water for 12 s in S and D groups.The rats were resuscitated according to Parkland formula after scald in S and D groups,and in addition,dexmedetomidine 30 μg/kg was also intraperitoneally injected immediately after scald in D group.Before the model was established (T1) and at 12 and 24 h after scald (T2,3),blood samples from the inferior vena cava were collected for determination of T lymphocyte subsets CD3 +,CD4 + and CD8 +,NK cell,C-reactive protein (CRP),interleukin-6 (IL-6),IL-10 and tumor necrosis factor-alpha (TNF-α) level.CD4+/CD8+ was calculated.Arterial blood samples were collected for blood gas analysis.Results Compared with C,the CD3+,CD4+ and NK cell levels,CD4+/CD8+,pH value,PaCO2 and PaO2 were significantly decreased,and CD8+ levels,IL-6,IL-10,TNF-α,CRP and BE negative value were increased at T2,3 in S and D groups.Compared with group S,the CD3+,CD4+,NK cell and IL-10 levels,CD4+/CD8+,pH value,PaCO2 and PaO2 were significantly increased,and CD8+ levels,IL-6,TNF-α,CRP and BE negative value were decreased at T2,3 in group D.Conclusion Dexmedetomidine can improve the cellular immune function of the rats with scald.

OBJECTIVE: To explore the effects of Yiqi Huayu Recipe, a compound traditional Chinese herbal medicine for replenishing qi and resolving stagnation, on transforming growth factor-beta1(TGF-beta1) of skin ulcers in rats with diabetes. METHODS: Sixty rats were randomly divided into six groups, Yiqi Huayu Recipe-treated group, Yiqi (replenishing qi) Recipe-treated group, Huayu (resolving stagnation) Recipe-treated group, basic fibroblast growth factor (bFGF) treated group, untreated group and normal control group. Diabetes was induced by peritoneal injection of streptozotocin and skin ulcers were made by surgery method in rats except for the normal control group. Then the rats were administered with different drugs respectively, and the expression of TGF-beta1 in granulation tissue of the skin ulcers was detected with the methods of Western blotting, image analysis and immunohistochemistry. RESULTS: The level of TGF-beta1 expression in the untreated group was lower than that in the normal control group (P<0.01); and the level of TGF-beta1 expression in the drug-treated groups was higher than that in the untreated group (P<0.01); and the TGF-beta1 expression in the Yiqi Huayu Recipe-treated group was higher than that in the Yiqi Recipe-treated group, Huayu Recipe-treated group and bFGF-treated group (P<0.05). CONCLUSION: The replenishing qi and resolving stagnation therapy can control the secretion of TGF-beta1 of the wound in the process of wound healing in the levels of gene and molecule.

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.

Objective To explore the influence of pelvis obliquity in lateral position to acetabular component orientation during total hip arthroplasty (THA),and the method to correct.Methods Fifty patients (62 hips) were performed THA with posterolateral incision in lateral position by the same team.The patients were randomized and divided into experimental group (EX,with 25 cases,34 hips) and control group (CON,with 25 cases,28 hips).In EX group,the acetabular components were placed by means of the gradienter and plumb correcting technique during THA.While in CON group,the acetabular components were placed by traditional method during THA.The acetabular abduction angles were measured postoperatively,and compared between the two groups.Results The average obliquity of pelvis was-1.647°±4.512°in EX group when putting the patient in lateral position before correcting.Through the application of gradienter and plumb,the average abduction angle of acetabular component was 42.685°±3.355° postoperatively,with the difference of 1.962°±1.515° compared with the preoperative angles.And in CON group,the average abduction angle of acetabular component was 44.534°±4.844° postoperatively,with the difference of 4.244°±3.042°.The difference of abduction angle in CON group was much higher than that in EX group (P＜0.05).Conclusion The pelvic obliquity when putting the patient under lateral position will affect the surgeons'judgments of placing acetabular component during THA,furthermore,lead to inconsistency among the abduction angles obtained preoperatively,intraoperatively and postoperatively.By applying the correcting method with gradienter and plumb,the discrepancy can reduce obviously between the abduction angle measured postoperatively and that of measured during operation comparing with traditional method.

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.
