RESUMO
Aldehyde dehydrogenase 2 (ALDH2) is one of important factors against from the damage under oxidative stress in human body. A high proportion of East Asians carry ALDH2 inactive mutation gene. There are many diseases closely related to ALDH2, such as cardiovascular diseases, neurodegenerative diseases and liver diseases. Recent studies also have found that ALDH2 is associated with ferroptosis. Therefore, ALDH2 has becoming a potential target for the treatment of the above related diseases. Several types of small molecule activators with potential value of clinical application have been reported. The research progress on the structure and function of ALDH2 , the relationship with human diseases and its activators were summarized in this paper.
RESUMO
ObjectiveTo observe the effects of Baihe Yuzi prescription (BYP) on the cystic fibrosis transmembrane conductance regulator (CFTR), aquaporin (AQP), zinc/iron-regulated transporter-like protein (ZIP) and local oxidative stress in epididymis of oligoasthenozoospermia (OAS) rats, and to explore the mechanism of its intervention in OAS. MethodAfter 35 rats were acclimatized for 1 week, 7 rats were randomly selected as the normal group, and the remaining 28 rats were given tripterygium glycosides (TG) 30 mg·kg-1. After 4 weeks of modeling, they were randomly divided into 4 groups: model group, BYP low-dose group (LBYP), BYP high-dose group (HBYP) and levocarnitine group, with 7 rats in each group. The rats in the normal group and model group were given normal saline at the same dosage. The levocarnitine group rats were given L-carnitine oral liquid (100 mg·kg-1) by gavage. The LBYP group rats were given BYP 6.3 g·kg-1, and the HBYP group rats were given BYP 12.6 g·kg-1 by gavage once a day for consecutive 4 weeks. After the end of the intervention, sperm count and motility of all rats were detected, the histopathological structure of epididymis was observed by hematoxylin-eosin (HE) staining, and the expressions of CFTR, AQP9, AQP3, ZIP8, ZIP12 and other proteins were detected by Western blot. The contents of α-glycosidase (α-GC), sialic acid (SA), carnitine, superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and malondialdehyde (MDA) were detected by enzyme-linked immunosorbent assay (ELISA). Total zinc content was measured using an inductively coupled plasma mass spectrometer. Free zinc ion content was detected by zinc ion probes. ResultCompared with those in the normal group, the sperm count and motility of rats were decreased and the epididymal structure was disordered in the model group. The contents of α-GC and carnitine were decreased in epididymis (P<0.05). MDA levels were increased, while SOD, GSH-Px and zinc levels were decreased (P<0.05). The expressions of CFTR and ZIP12 in the head and cauda of the epididymis were down-regulated, and AQP3 expression was up-regulated. The expression of ZIP8 in the cauda epididymis was up-regulated (P<0.05). Compared with the model group, BYP can significantly improve the sperm count and motility, the epididymal structure of OAS rats and the levels of α-GC and carnitine (P<0.05). The expressions of CFTR and ZIP12 in the head and cauda of the epididymis were up-regulated, while the expressions of ZIP8 in the cauda epididymis and AQP3 in the head of the epididymis were decreased (P<0.05). The SOD and GSH-Px levels and total zinc content in epididymis were increased, and the MDA levels were decreased (P<0.05). ConclusionBYP may improve the sperm quality and repair epididymal tissue structure and function of OAS rats, by regulating the expressions of CFTR, AQP3, and ZIP12 ion channels and local antioxidant mechanism.
RESUMO
Objective:To analyze the hospitalization costs of delivery for postpartum women with different delivery methods, ages and comorbidities or complications, for references for medical institutions and medical insurance management departments to develop payment and compensation standards for inpatient delivery.Methods:The first page of medical records of hospitalized delivery women admitted to 8 large tertiary hospitals in Beijing from January 2018 to December 2021 were selected. Descriptive analysis was made on the mode of delivery, age, hospitalization expenses and cost structure of puerpera, as well as the hospitalization expenses of puerpera with different complications or complications. Wilcoxon rank sum test, Kruskal-Wallis H test, and Chi-squared test were used to statistically compare the level and structure differences between groups. Results:A total of 23 320 pregnant women were included, with an average age of 32.3 years. There were 13 605 cases of natural delivery and 9 715 cases of caesarean section. The median cesarean section rate in the right age group (<35 years old) and the elderly group (35-50 years old) were 36.73% and 56.58%, respectively, and the median hospital expenses were 5 865 yuan and 7 042 yuan, respectively. The median hospital expenses for natural delivery and caesarean section were 4 452 yuan and 10 033 yuan, respectively. The highest proportion of hospitalization expenses for natural delivery and cesarean section were treatment expenses (23.45%) and medicine expenses (29.19%), respectively. The median of hospitalization cost for women with≥2 comorbidities or complications (6 736 yuan) was higher than that for women with 1 comorbidities or complications (5 794 yuan).Conclusions:The hospitalization cost of cesarean section was significantly higher than that of natural delivery and the rate of cesarean section and the cost of delivery in women aged 35 and above were higher than those under 35 years old. The structure of hospitalization cost was different in different delivery modes, and the complications or complications had a greater impact on the average hospitalization expenses.
RESUMO
@#Objective To compare clinical effects of enlarged thymectomy for the treatment of myasthenia gravis (MG) complicated with thymoma via subxiphoid and subcostal arch thoracoscopic resection versus median sternotomy resection. Methods We retrospectively analyzed the clinical data of patients with MG complicated with thymoma admitted in Tangdu Hospital of the Air Force Military Medical University between December 2011 and December 2021. Patients who underwent subxiphoid and subcostal arch thoracoscopic enlarged thymectomy were allocated to a SR group, and patients who underwent median sternotomy enlarged thymectomy were allocated to a MR group. Perioperative outcomes were compared between the two groups. Results A total of 456 patients were collected. There were 51 patients in the MR group, including 30 males and 21 females aged 23-66 (49.5±11.8) years. There were 405 patients in the SR group, among whom 51 patients were matched to the MR group by propensity score matching, including 28 males and 23 females aged 26-70 (47.2±12.2) years. The operations were accomplished successfully in all patients, and no conversion to thoracotomy occurred in the SR group. The SR group had advantages in the operation time, intraoperative blood loss, chest drainage duration, hospital stay time, patients’ satisfaction level, pain score and complications (all P<0.05). No statistical difference was found in the number of intraoperative lymph node dissection stations, number of intraoperative lymph nodes dissected or remission of MG between the two groups (P>0.05). Conclusion Subxiphoid and subcostal arch thoracoscopic enlarged thymectomy and lymphadenectomy is a safe, effective and feasible minimally invasive procedure for the treatment of MG complicated with thymoma.
RESUMO
Objective:This work aims to investigate the phenotype-characteristics of drug resistance and the possible mechanisms of extensively drug-resistance Klebsiella pneumoniae(XDRKP). Methods:Screened by the previous drug susceptibility results, 116 clinical Klebsiella pneumoniae isolates were collected from Shanxi Bethune Hospital from January 2018 to December 2020. Matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF MS) rapid microbial identification system and VITEK-compact 2 were used. The modified carbapenem inactivation method (mCIM) combining with EDTA carbapenem inactivation method (eCIM) was used to identify the strains′ carbapenemase phenotypes, which were compared with subsequent qPCR results. The qPCR amplification combining with agarose gel electrophoresis were carried out to detect various drug-resistant related genes, including: carbapenemase genes: blaKPC, blaNDM, blaVIM, blaIMP, blaOXA; aminoglycosides resistance genes: ① 16S rRNA methylase genes: rmtA, rmtC, rmtD, rmtG, rmtH, armA, npmA, rmtB, rmtE, rmtF, ② variant of aminoglycosides acetyltransferase gene: aac(6′)-Ib-cr; quinolone resistance genes: DNA gyrase protection protein qnr family: qnrA, qnrB, qnrC, qnrD, qnrS, efflux pump protein gene: oqxAB, qepA, variant of aminoglycoside acetyltransferase gene: aac(6′)-Ib-cr; and tigecycline-resistant Tet protein genes: efflux pump protein gene: tet (A), tet (L), ribosome protection protein gene: tet (M), tigecycline modified enzyme gene: tet (X). Each isolate′s phenotype and resistance gene result were compared and analyzed correspondingly. Results:A total number of 116 XDRKP isolates were collected in 3 years, 115 of which are identified as carbapenem resistant. Both cephalosporins and quinolones resistant rate were 100%, while the resistant rate of aminoglycosides antibiotic gentamicin, tobramycin and amikacin was 95.69% (111/116), 94.83% (110/116), or 88.79% (103/116) respectively. Sulfonamide antibiotics and tigecycline showed a relatively lower resistant rate. Compared with PCR amplification results, mCIM combining with eCIM phenotype testing had a high conformity, up to 95.65% (110/115). Positive rate of each resistance related gene was: blaKPC 90.52% (105/116), blaNDM 10.34% (12/116), rmtB 81.90% (95/116), armA 2.59% (3/116), oqxAB 65.52% (76/116), qnrB 6.03% (7/116), qnrS 12.93% (15/116), aac(6′)-Ib-cr 7.76% (9/116), or tet(A) 21.55% (25/116), respectively. Other resistance related genes were not detected. Corresponding analysis between the resistant phenotypes and resistance related genes indicated that a total of 65 XDRKP didn′t have a matched pairs, i.e. bacteria′s resistance to specific antibiotic could not be interpreted by carrying some associated resistant genes.Conclusions:The wide distribution of resistant genes and multiple-antibiotic-inactivated trait of some genes(such as aac(6′)-Ib-cr and oqxAB) in XDRKP are potential causes of the generation of extensively drug resistant phenotype. Different XDRKP isolates may carry one or more resistant genes in responding to specific antibiotic. In addition, there are some bacteria with an unmatched phenotype-gene feature indicating that both resistance genes′ regulation and some other mechanisms also play a role in development of XDR.

@#Objective To compare clinical effects of extended thymectomy for the treatment of thymic abnormalities with myasthenia gravis (MG) between subxiphoid and subcostal arch thoracoscopic resection (SR) and the unilateral thoracoscopic resection (UR) by a propensity-score matching analysis. Methods We retrospectively analyzed the clinical data of 612 patients who presented with MG and were admitted to Tangdu Hospital of Air Force Military Medical University between December 2011 and December 2018. Of these patients, 520 patients underwent subxiphoid and subcostal arch thoracoscopic extended thymectomy (a SR group) and 92 unilateral thoracoscopic extended thymectomy (a UR group). Ninety-two patients in the SR group were matched with the UR group by propensity-score matching analysis. There were 52 males and 40 females with an average age of 26-70 (50.2±10.3) years in the SR group, and 47 males and 45 females with an average age of 20-73 (51.5±12.1) years in the UR group. The operation time, intraoperative blood loss, thoracic drainage time, postoperative hospital stay, thorough adipose tissue removal, postoperative remission of MG, patients’ satisfaction score, pain and complications were compared and analyzed between the two groups. Results All operations were accomplished successfully, without conversion to thoracotomy of the two groups. There were statistical differences between the two groups in operation time (46.2±19.5 min vs. 53.4±23.5 min), chest drainage duration (0 d vs. 3.4±1.2 d), hospital stay (2.9±1.9 d vs. 3.6±1.7 d), patients’ satisfaction score (7.9±2.1 points vs. 6.7±1.2 points) and pain scores (all P<0.05). There were no statistical differences between the two groups in intraoperative blood loss (52.2±12.7 mL vs. 51.2±10.3 mL), peripheral adipose tissue removal (8.1±0.6 vs. 7.9±0.9), remission rate of MG (89.1% vs. 85.9%) and rate of postoperative complications (10.9% vs. 6.5%) (all P>0.05). Conclusion Subxiphoid and subcostal arch thoracoscopic extended thymectomy is a safe and feasible minimally invasive procedure for the management of MG with thymic abnormalities.
RESUMO
OBJECTIVE: To systematically evaluate current status of charges in pharmacy intravenous admixture services (PIVAS), and to provide reference for the formulation of China’s pharmacy intravenous admixture services (PIVAS) charging standards. METHODS: Retrieved from PubMed, Embase, Cochrane library, CBM, CNKI, VIP, Wanfang database and related goverment websets, the literatures about current status evaluation of charges in PIVAS of China were collected during the establishment of database to Jan. 2019. Cost estimation, charge standard, influential factors and other indicators were collected, and the results were presented by descriptive analysis. RESULTS: A total of 5 literatures were included, all of which were reviewed. According to the existing literatures, except for Shandong, Guangdong and Yunnan provinces, there were no regional charge standards in other provinces (districts and cities). The cost estimation methods of PIVAS in these three provinces were basically the same. The cost could be obtained by adding up the business fees, labor fees, fees of medical instruments purchase and use, indirect fees etc. Dispensing charges in PIVAS were 3-5 yuan per piece for general drug, 5 yuan per piece for antibiotics and 8-12 yuan per piece for cancer chemotherapeutics, 20-35 yuan per piece for TPN. The charging level was mainly affected by local prices, PIVAS scale, hardware investment, management and other factors. CONCLUSIONS: There is no unified charging standard for PIVAS in most provinces (districts, cities) of China. The cost estimation methods of the hospitals from the included literatures are basically the same. It is necessary to construct national PIVAS charging standard and cost estimation method, which could provide a basis for formulating the price of medical and health services.

RESUMO
Objective@#To screen the risk factors of patients with frequent acute exacerbation of chronic obstructive pulmonary disease (COPD) by detecting the clinical indicators of periodontitis and the level of bacterial and inflammatory markers in saliva.@*Methods@#Thirty-eight COPD patients in their stable period were recruited and detected from Beijing Chao-Yang Hospital,Capital Medical University during December 2016 to May 2017. The periodontal index were recorded. The levels of inflammatory factors in saliva samples were examined by using enzyme linked immunosorbent assay (ELISA). The bacteria composition in the saliva samples were identified by using 16SrRNA gene pyrosequencing. All patients were followed up and monitored for acute exacerbation of COPD for 12 months. The patients were divided into frequent acute exacerbation group (≥2 times/year, n=10) and non frequent acute exacerbation group (<2 times/year, n=28).@*Results@#In univariate analysis, the patients′ average age of frequent acute exacerbation group (69.0±7.3) was significantly older than that of non-frequent acute exacerbation group (61.8±8.3) (P=0.02). The numbers of remaining teeth ≤26 [100% (10/10)] was significantly higher and plaque index ≤2.5 (2/10) in frequent acute exacerbation group was significantly lower compared with the remaining teeth ≤26 [43% (12/28)] and the plaque index ≤2.5 [71% (21/28)] in non-frequent acute exacerbation group (P=0.02, P=0.01). The proportions of salivary inflammatory factors interleukin-6 (IL-6) level ≤60 ng/L (10%),C-reactive protein (CRP) level ≤1 550 μg/L (30%), matrix metalloproteinase-8 (MMP-8) level ≤140 μg/L (30%) and fibrinogen level ≤90 mg/L (30%) in frequent acute exacerbation group were significantly lower compared with salivary inflammatory factors IL-6 level ≤60 ng/L (71%),CRP level ≤1 550 μg/L (71%), MMP-8 level ≤140 μg/L (86%) and fibrinogen level ≤90 mg/L (71%) in non-frequent acute exacerbation group (P<0.05). The differences of relative abundances of salivary bacteria,such as species of Chloroflexi, Anaerolineae, Anaeroales, Corynebacteriales, Anaerolineaceae, Tissierellaceae, Leptotrichiaceae, Corynebacteriaceae, Leptotrichia, Moryella, Lachnoanaerobaculum and Corynebacterium between frequent acute exacerbation group and non-frequent acute exacerbation group were significantly different (P<0.05). In multivariate logistics regression analysis,the level of IL-6 >60 ng/L and the relative abundance of Corynebacteriales >0.2 had significant difference (P<0.05).@*Conclusions@#The level of IL-6 and the relative abundance of Corynebacteriales might be the markers of frequent acute exacerbation in COPD patients.
RESUMO
OBJECTIVE: To systematically evaluate the status quo of cost estimation in pharmacy intravenous admixture services (PIVAS), and to provide cost basis for the construction of PIVAS in China. METHODS: Retrieved from PubMed, Embase, Cochrane library, CBM, CNKI, CSJD and Wanfang database from database establishment to Jan. 2019, the studies about the status quo of cost estimation in PIVAS of China were included. The descriptive analysis was conducted for content and method of cost estimation, infection to hospital. RESULTS: A total of 17 literatures were included, involving 8 before and after control studies, 6 experience sharing studies and 3 reviews. Existing reports showed that the estimation contents and methods of PIVAS cost were roughly the same. The cost included manpower, medical and health materials, fixed asset purchase, depreciation, repair costs, medicine cost and indirect costs. At the same time, the infection to hospital were reported, such as in manpower adopting, formulating detailed management measures and systems, concurrent allocation of the same kind of drugs, shortening infusion preparation and replacement time, in order to save manpower cost. CONCLUSIONS: PIVAS cost calculation method is roughly the same in some hospitals, but there is no uniform standard. It is necessary to further improve the PIVAS cost measurement standard and provide a basis for the construction and development of PIVAS in China.

Objective To investigate the effect of concentrated suture fixation in subdermal vascular network flap method for treatment of axillary osmidrosis in reducing postoperative complications,increase the wound dressing effect of comfort.Methods Ninety-six cases of bilateral axillary osmidrosis patients were randomly divided into concentrated suture group (group A) and 8 bandage compression group (group B),48 cases in each group.They were cleared of sweat gland retaining subdermal vascular network skin flap method in treatment of axillary osmidrosis.Group A was treated with concentrated suture fixation after the separation of the subdermal vascular network flap by in situ,group B was treated by routine compression bandage fixation after the separation of the subdermal vascular network flap.Observation of subcutaneous hematoma,infection,necrosis of skin after operation and understood dressing comfort.To observe the peculiar smell and axillary scar,operation area 6 months postoperative growth.Results The postoperative observation:group A subcutaneous hematoma complication rate was lower in group B,the incidence of 1.04% (1/96) vs.19.79% (19/96),the difference was statistically significant (P < 0.01).Group A postoperative dressing comfort satisfaction rate was 93.75% (45/48),group B po or comfort,satisfaction rate was only 10.42%(5/48),the difference had statistically significant (P < 0.01).After 6 months of postoperative,the total efficiency of two groups were 100.00%,no significant difference (P > 0.05).Group A district scar formation rate was higher than that in group B [3.12%(3/96) vs.21.88%(21/96)] (P < 0.05).The armpit hair and sweat in the two groups was significantly reduced,there was no significant difference (P > 0.05).Conclusion Concentrated suture fixation method in the treatment of axillary osmidrosis by subdermal vascular network is a reliable fixation of the axillary free after the subdermal vascular network flap,and have flap high healing rate,scar,low rate of complications; postoperative dressing is simple,comfortable,living freely,overall is better than 8 bandage compression method.
