DNA double-strand break repair capacity and its pathway gene variants predict the risk and prognosis of lung cancer.

OBJECTIVES: This study aims to investigate the association between DNA double-strand breaks (DSBs) repair capacity, variations in DSBs-related genes, and the occurrence and prognosis of lung cancer in the Chinese population. METHODS: Peripheral blood mononuclear cells (PBMC) were collected from 98 lung cancer patients and 60 healthy individuals. The individual DSBs repair capacity was assessed by measuring changes in γ-H2AX levels after treatment with etoposide. Exonic sequencing of 45 DSBs-related genes was performed on PBMC DNA. Logistic regression analysis was conducted to examine the relationship between lung cancer risk and DSBs repair capacity as well as germlines gene variations. Survival analysis employed the Cox proportional hazards regression model, Kaplan-Meier method, and Log-rank test. RESULTS: Lower DSBs repair capacity predicted an increased risk of developing lung cancer (OR = 0.94, 95 %CI = 0.917-0.964, P＜0.001). Among lung cancer patients, higher DSBs repair capacity was associated with shorter progression-free survival (PFS) during first-line treatment (HR = 1.80, 95 %CI = 1.10-3.00, P = 0.031). Patients with BRCA1 mutations had shorter overall survival (OS) (HR = 1.92, 95 %CI = 1.12-3.28, P = 0.018). Patients with FOXO3 mutations had shorter PFS (HR = 4.23, 95 %CI = 1.44-12.36, P = 0.009). Analysis of patients treated with immune checkpoint inhibitors (ICIs) indicated that LIG4 mutations were associated with shorter PFS (HR = 2.90, 95 %CI = 1.00-8.10, P = 0.041). CONCLUSIONS: This study concludes that assessing DSBs repair capacity holds promise for predicting both lung cancer risk and prognosis in the Chinese population. Further large-scale studies and functional validation of specific gene mutations related to double-strand breaks are necessary for confirmation.

Mechanism of Wen Shen Xuan Bi Tang in treatment of osteoporosis based on network pharmacology and animal experimental verification / 中国药理学通报

Aim To predict and validate the mechanism of wenshen xuanbi tang(WSXBT) in treatment of osteoporosis (OP) based on network pharmacology, molecular docking techniques and in vivo experimental techniques. Methods Network pharmacology was used to screen the key ingredients and core targets of WSXBT for the treatment of osteoporosis. Metascape database was used for gene ontology (GO) biological process enrichment analysis and kyoto encyclopedia of genes and genomes (KEGG) signaling pathway enrichment analysis of core targets. AutoDockTools 1. 5. 7 software was applied in molecular docking to simulate the binding activity of key active ingredients to core targets. To study the efficacy of WSXBT on rats with osteoporosis and to verify the related targets and pathways, rat models of osteoporosis were established by excising the bilateral ovaries of rats. Enzyme-linked immunosorbent assay (ELISA) was used to detect the serum OPG, PINP and RANKL content. Biomechanical tester was applied to test the biomechanics of rat femurs. Micro-CT was applied to detect the femoral bone density. Then, Western blot was employed to measure the protein expression levels of phosphatidylinositol 3-kinase (PI3K) and protein kinase B (Akt). Results A total of 156 active ingredients of WSXBT were screened, involving 229 potential targets, 23 core targets and 145 signaling pathways. The molecular docking results showed that five key ingredients, including quercetin, kaempferol, naringenin, isobavachin and licochalcone a, possessed good binding ability to the core targets of PIK3R1 and AKT1. The results of in vivo experiments showed that WSXBT could significantly increase bone density, improve bone tissue microstructure, enhance femur biomechanics and increase PINP expression and OPG/RANKL ratio in rats with osteoporosis. Results of WB showed that WSXBT significantly increased p-PI3K/PI3K and p-Akt/Akt ratios. Conclusions WSXBT could improve bone mineral density in postmenopausal osteoporotic rats through PI3K/ Akt signaling pathway and increasing OPG/RANKL ratio.

Influence factors of bone mineral density and its correlation with insulin resistance in obese children in Qianjiang area / 公共卫生与预防医学

Objective To explore the influencing factors of bone mineral density (BMD) in obese children in Qianjiang area and analyze the correlation between BMD and insulin resistance. Methods The data on pediatric cases from the outpatient department of Jianghan Oilfield General Hospital in Qianjiang from January 2018 to December 2022 were collected. A total of 183 obese children who met the inclusion and exclusion criteria were included in the study and selected in the observation group. A total of 352 children undergoing physical examination during the same period were selected as the control group. Results The body mass, waist circumference, waist to hip ratio, and BMI of obese children were significantly higher than those of the control group (P<0.001). Biochemical indexes including FBG, FINS, Home-IR, ALP, and LDL-C in obese children were significantly higher than those in the control group (P<0.05), while bone mineral density, Ca, P, sOC and HDL-C were significantly lower than those in the control group (P<0.001). The bone mineral density of obese children was significantly correlated with their exercise intensity, sunshine exposure duration, sitting time, intake of milk and dairy products, intake of sweets, supplementation of trace elements, BMI, Home-IR, and sex (all P<0.05). BMI, Home-IR, sex, exercise intensity, and sunshine exposure length were independent risk factors affecting bone mineral density of obese children (all P<0.05). Bone mineral density was negatively correlated with BMI and Home-IR (P=0.028 and0.017, respectively), and positive correlation with exercise intensity and sunlight exposure (P=0.033). Conclusion BMD of obese children in Qianjiang area is affected by gender, body mass index, diet, vitamin intake, and physical activity, and is negatively correlated with insulin resistance. Home-IR can be used as a reference for screening BMD of obese children.

Bisphenol A and its analogue bisphenol S exposure reduce estradiol synthesis via the ROS-mediated PERK/ATF4 signaling pathway.

As a kind of endocrine-disrupting chemicals, BPA may affect the human placenta. Due to consumer unease about BPA, many manufacturers are using alternatives to BPA, such as BPS. However, some reports suggest that BPS may produce similar results to BPA. To understand how BPA/BPS leads to reduced synthesis of placental estradiol (E2), we conducted studies using a human choriocarcinoma cell (JEG-3) model for research. In this study. Elisa assay revealed that both BPA/BPS exposures decreased E2 synthesis in JEG-3 cells. The results of RT-PCR showed that both BPA and BPS could reduce the mRNA expression of CYP19A1, a key enzyme for E2 synthesis in JEG-3 cells. In addition, Western blot assay showed that BPA/BPS-induced ER-stress PERK/eIF2α/ATF4 signaling protein expression was increased. The expression of ROS in cells after exposure to BPA/BPS was detected using the 2,7-dichlorodihydrofluorescein diacetate (DCF-DA) method. The results of this experiment showed that BPA/BPS significantly induced an inhibition of ROS in JEG-3 cells. The present study concluded that, firstly, BPS exposure induced almost the same effect as BPA in reducing E2 synthesis in JEG-3 cells. Second, BPA/BPS exposure may reduce E2 synthesis in JEG-3 cells by increasing ROS levels and thus activating endoplasmic reticulum stress.

Investigation on the precipitate morphology and fraction characterization by atomic force microscopy.

Precipitate was typically characterized by the transmission electron microscopy (TEM) or scanning electron microscopy (SEM) to analyze the relationship between material property and precipitate fraction. However, these procedures tend to be are always time consuming because of the complicated sample preparation process involved and the observation course. Particularly, sometime the precipitate can't be highlighted solely from the images easily. In this study, atomic force microscopy (ATM) was performed to characterize the morphology and fraction of the precipitate in this paper. Five kinds of materials were selected and prepared by electropolishing or vibration polishing method to display the precipitates on the sample surface. The experiment results prove that different types of precipitates with higher values for height on a sample surface could be clearly observed by AFM, and the images quality is highly relied upon the surface quality. The precipitate fraction can be calculated using the AFM micrographs and image photo post treated software (IPP). It was turned out that AFM is found suitable for observation almost all kinds of precipitates, and the precipitates can be easily separated from the images. Not only vibration polishing but also electrolytic polishing could offer a smooth surface for observing nanosized precipitates by AFM. A comparison of the fraction result obtained by AFM and precise microchemical analysis proves that the fraction measurement result obtained by AFM is acceptable.

Discrepancy in ingroup bias among different self-construal individuals: The moderating role of group types.

Although ingroup bias is well confirmed in various groups, the extent of the bias is affected by culture. Using a point-assignment task and implicit association task (IAT) paradigm, we conducted research to explore the influence of independent/interdependent self-construal ingroup bias in live and minimal group situations from both explicit and implicit aspects. The results showed that no matter which construal style was used (independent or interdependent self-construal), participants showed ingroup bias in both live and minimal groups. In the minimal group condition, the ingroup bias of individuals with independent self-construal was significantly higher than that of individuals with interdependent self-construal. Conversely, in the live group condition, the ingroup bias of individuals with interdependent self-construal was significantly higher than that of individuals with independent self-construal. This study showed the influence of independent/interdependent self-construal on ingroup bias and group type is a moderating variable. Results indicate that group categorization may play an essential role in ingroup bias of different group types.

Clinical features of patients with local recurrence and secondary operation after partial nephrectomy for renal cancer / 中华泌尿外科杂志

Objective:To investigate the clinical features of patients with local recurrence and secondary operation after partial nephrectomy for renal cancer.Methods:The clinical data of 14 patients who underwent secondary operation for local recurrence of renal cancer after partial nephrectomy in the First Affiliated Hospital and the Second Affiliated Hospital of Naval Medical University from January 2000 to January 2022 were retrospectively analyzed. There were 12 males and 2 females. Nine patients had a body mass index ≥24 kg/m 2. At first diagnosis of renal cancer, nine patients’ R. E.N.A.L. score of renal mass were at least 7. Partial nephrectomy was performed in the first operation of each patient, including 4 cases of open surgery, 6 cases of laparoscopic surgery, and 4 cases of robot-assisted laparoscopic surgery. The pathological stage of nine patients was pT 1aN 0M 0 and that of five patients was pT 1bN 0M 0. Twelve cases were clear cell carcinoma, 1 case was sarcomatoid carcinoma and 1 case was chromophobe cell carcinoma. The mean time from the first operation to local recurrence was (29.3±16.8) months. All recurrence lesions were found by abdominal CT or MRI. Thirteen patients had no clinical symptom at the time of tumor recurrence. The location of recurrence was clear. No sign of invasion of peripheral organs and tissues was observed. There was no other suspicious lesion. The tumor was considered to be completely resectable in all patients. All 14 cases underwent secondary operation. Ten patients underwent radical nephrectomy [tumor size was (2.8±0.9) cm]. Partial nephrectomy was performed in 4 cases [tumor size was (1.8±0.9) cm]after full evaluation by surgeons, including 2 cases of anatomic solitary kidney, and 2 cases of recurrent tumor less than 2 cm with clear tumor margin. Results:Eleven of the 14 cases underwent minimally invasive surgery, and no cases were converted to open surgery. The other 3 cases underwent open surgery. Seven patients had severe adhesions in the operation area. The blood loss in the partial nephrectomy group and the radical nephrectomy group was (100.0±70.7) ml and (143.0±81.2) ml, respectively. According to the Clavien-Dindo classification of surgical complications, Grade Ⅰ and Grade Ⅱ complication occurred in 1 patient respectively, and no patient had Grade Ⅲ or above complication. No tumor cell was found at the surgical margin. The pathological type and nuclear grade were the same as those in the first operation. There were 10 cases of pT 1aN 0M 0 stage, 3 cases of pT 3aN 0M 0 stage and 1 case of pT 3aN 1M 0stage. The follow-up time of 13 patients with complete follow-up data was (21.4±14.9) months after local recurrence resection. The tumor recurred in 3 patients and metastasized in 2 patients. The disease-free survival time of the above 5 patients was (13.2±8.8) months. Of the 4 patients who underwent partial nephrectomy, 3 had recurrence or metastasis. Among the 9 patients who underwent radical nephrectomy, 2 had postoperative recurrence or metastasis, and 7 patients survived without tumor until the last follow-up. Conclusions:For patients with local recurrence after partial nephrectomy who are in good condition and the recurrent lesions can be completely resected, the second operation is safe, feasible and effective. Patients with secondary radical nephrectomy have better prognosis. If the patient has a solitary kidney, the recurrent tumor is small and the margin is clear, partial nephrectomy can also be selected for the second operation. But the postoperative follow-up should be emphasized, and the adjuvant drug therapy should be given if necessary.

A clinical research on relationship between sepsis-induced coagulopathy and prognosis in patients with sepsis / 中华急诊医学杂志

Objective:To evaluate the prognostic value of sepsis-induced coagulopathy (SIC) in patients with sepsis.Methods:From January 2019 to December 2021, patients with sepsis admitted to the Intensive Care Unit of our hospital were retrospectively classified into the SIC group and non-SIC group according to SIC diagnostic criteria. The baseline clinical data, severity score, total length of hospital stay, length of ICU stay and 28-day survival were compared between the two groups. Kaplan-Meier was used to compare the 28-day survival of patients with sepsis between the two groups. Cox proportional hazard regression model was employed to analyze the risk factors of prognosis in patients with sepsis.Results:Totally 274 patients with sepsis were included in the analysis, including 139 patients in the SIC group and 135 patients in the non-SIC group. The two groups were compared in the perspectives of the Platelet count (PLT), prothrombin time (PT) , procalcitonin (PCT), D dimer, hematocrit, red blood cell distribution width, hemoglobin, acute kidney injury (AKI), the use of continuous renal replacement treatment (CRRT), the use of vasoactive drugs, sequential organ failure assessment (SOFA) score, acute physiology and chronic health evaluation (APACHEⅡ) score were compared between the two groups and the difference were statistically different (all P<0.05). Kaplan-Meier analysis showed that the 28-day mortality rate in the SIC group was significantly higher than that in the non-SIC group (32.4% vs. 14.1%, P<0.05). COX proportional hazard model showed that SIC score ( HR= 2.17, 95% CI: 1.15-3.91, P<0.05), APACHEⅡ score ( HR= 1.13, 95% CI: 1.09-1.17, P<0.05) and the use of vasoactive drugs ( HR=3.66, 95% CI: 1.53-8.75, P<0.05) were independent influencing factors for 28-day death in patients with sepsis. Conclusions:Patients with sepsis and SIC have more severe disease and increased mortality risk. SIC score exhibits good clinical value in predicting the prognosis of patients with sepsis.

Effects of dopamine on oxidative stress and VEGF expression in retinal tissues of rats with diabetic retinopathy model / 国际生物医学工程杂志

Objective:To investigate the effect of dopamine on oxidative stress and vascular endothelial growth factor (VEGF) expression in the retinal tissue of diabetic retinopathy (DR) model rats.Methods:Ninety rats were randomly divided into three groups: the control group, the model group, and the dopamine group, with 30 rats in each group. In the dopamine group, the DR model was established by a high-sugar and high-fat diet for four consecutive weeks, and no drug intervention was given to the control or model groups. The eyes of rats in the dopamine group were injected intravitreally with 50 mg/kg dopamine solution. The retinal tissues of the rats in the three groups were observed under a light microscope after hematoxylin-eosin staining. The levels of catalase (CAT), superoxide dismutase (SOD), malondialdehyde (MDA), monocyte chemotactic protein-1 (MCP-1), interleukin-6 (IL-6), and VEGF were detected by enzyme-linked immunosorbent assay (ELISA) in the retinal tissues of the rats in the three groups. Western blot was used to detect VEGF expression in the three groups of rats.Results:In the control rats, the inner retinal border membrane was flat, with fewer neovascular endothelial cells protruding into the vitreous, and no neovascularization connected to the inner membrane reaching the intravitreous was observed. Compared with the control group, rats in the model group had more vascular endothelial cells breaking through the inner border membrane, and significant cellular proliferation was observed under the inner border membrane. Compared with the model group, rats in the dopamine group had a less flat inner retinal border membrane, fewer neovascularized endothelial cells protruding into the vitreous, and less cellular proliferation under the inner border membrane. Compared with the control group, CAT and SOD levels were decreased, while MDA, MCP-1, IL-6, and VEGF levels were increased in the model group, and the differences between the two groups were statistically significant (all P < 0.05). Compared with the model group, CAT and SOD levels were increased in the dopamine group, while MDA, MCP-1, IL-6, and VEGF levels were decreased, and the differences between the two groups were statistically significant (all P < 0.05). Conclusions:Dopamine up-regulated CAT and SOD levels and down-regulated MDA, MCP-1, IL-6 levels, and VEGF expression in the retinal tissues of DR rats.

Regulation of gluconeogenesis in liver, kidney and intestine by glucagon / 中国药理学通报

Aim To investigate the regulatory effect of glucagon on gluconeogenesis in liver, kidney and intes¬tine during different fasting periods and the underlying mechanism. Methods The 8-week-old male C57BIV 6J mice were randomly divided into six groups ( n = 6) :control group, control + glucagon group, fasting 18 h group, fasting 18 h + glucagon group, fasting 36 h group, and fasting 36 h + glucagon group. Glucose, triglyceride ( TG) and free fatty acids ( FFAs ) kits were used to detect their serum contents in mouse in-traperitoneal injection of glucagon at different fasting time points. Besides, liver/muscle glycogen assay kit and PAS staining were used to detect the glycogen con¬tents in liver tissue. RT-PCR method was used to observe the effects of glucagon on the gene expressions of peroxisome proliferators-activated receptor y coactivator la (PGC-1α), glucose-6-phosphatase (G6Pase) and phosphoenol pyruvate carboxykinase 1 (PEPCK) in liver, kidney and intestine of mice at different fasting time. Western blot was employed to detect the protein expressions of PGC-1α, G6Pase, PEPCK, phosphoryl-ase protein kinase A ( p-PKA) , protlein kinase A (PKA) , phosphorylase cAMp-response element binding protein (p-CREB) and cAMp-response element binding protein (CREB) in liver, kidney and intestine of mice were. Results (1) Glucagon increased the serum glucose level, reduced serum TG and FFAs levels, and reduced the hepatic glycogen content. (2) Glucagon promoted gluconeogenesis via upregulation of PGC-1α. On the stimulation of glucagon, PGC-1α gene and protein expressions in liver were significantly raised by glucagon when the mice were fasted 18 h and 36 h, while the gene and protein expressions of PGC-1α in kidney were obviously up-regulated by glucagon after fasting 18 h. However, PGC-1α gene and protein expressions in intestine were significantly elevated by glucagon at 36 h after fasting. (3 ) Glucagon induced gene and protein expressions of gluconeogenesis-related enzymes G6Pase and PEPCK in liver, kidney and intestine after fasting. (4 ) Glucagon upregulated p-PKA/PKA and p-CREB/CREB in liver. Conclusions Glucagon shows temporal difference in the gluconeo-genic response of liver, kidney and intestine in mice. Glucagon promotes the gene and protein expressions of key gluconeogenic enzymes G6Pase and PEPCK by increasing PGC-1α gene and protein expression, and thus increasing fasting blood glucose. Besides, glucagon promotes hepatic gluconeogenesis via PKA/CREB signaling pathway.

Advances in the study of natural small molecules to protect the intestinal epithelial tight junction barrier in inflammatory bowel disease / 中国药理学通报

Inflammatory bowel disease (IBD), as an idiopathic inflammatory disease of the intestinal tract, consisting mainly of Crohns disease and ulcerative colitis, which can involve the rectum, colon and ileum, and whose pathogenesis is still not fully understood. The initiation of intestinal inflammation associated with IBD and its chronieity begins with increased intestinal permeability caused by intestinal epithelial barrier disruption. The anti-permeability of the intestinal epithelial barrier is maintained by tight junction in the apical region of the intestinal epithelial cells, and disruption of the tight junction structure is closely associated with intestinal epithelial barrier damage and the development of IBD. Therefore, it is significant to find drugs for the prevention and treatment of IBD using tight junctions as regulatory targets. In recent years, many small molecules of natural product origin have been reported to improve the effects of IBD. In particular, we review the compounds that have the function of repairing intestinal epithelial barrier and protecting tight junction structure, in order to provide research ideas for the design and development of new drugs for the prevention and treatment of IBD.

Application of multiplex PCR capillary electrophoresis and analysis of distribution characteristics of HPV infection subtypes / 中华预防医学杂志

Objective: To analyze the characteristics of human papillomavirus (HPV) infection and the distribution of HPV subtypes in Shijiazhuang, Hebei Province, and to explore the application evaluation of multiple PCR capillary electrophoresis fragment analysis for HPV typing test. Methods: A population-based cross-sectional study was conducted among 434 women (age range 17 to 74 years old, 260 patients and 174 physical examinations) included from May to August 2022 in Hebei General Hospital. HPV typing was detected by multiple PCR-capillary electrophoresis fragment analysis. Using the multiple fluorescence quantitative PCR kit as a reference, Chi-square test was used to analyze the diagnostic effect of multiple PCR-capillary electrophoresis fragment analysis, and the consistency was analyzed by Kappa value. Results: The total HPV infection rate was 45.85%(199/434), including 35.48% (154/434) of high-risk HPV (HR-HPV), 3.92% (17/434) of low-risk HPV (LR-HPV), 6.45% (28/434) of HR-HPV and LR-HPV mixed infection, 27.88% (121/434) of single type HPV and 17.97% (78/434) of multi type HPV. HPV52 (9.68%, 42/434), HPV16 (6.91%, 30/434), and HPV58 (6.91%, 30/434) are common HPV subtypes. The positive rate of physical examination was 45.40% (79/174), which was slightly lower than that of patients 46.15% (120/260), there was no significant difference (χ2=0.024,P>0.05). The highest infection rate in the 17-30 age group was 54.76% (46/84), and there was no statistical difference among the age groups(χ2=4.123,P>0.05). The sensitivity and specificity of multiplex PCR capillary electrophoresis fragment analysis were 92.96% and 94.04%, respectively, and Kappa value was 0.870, with the multiplex fluorescent quantitative PCR as the reference. Conclusion: HPV infection may appear younger, and the positive rate of HR-HPV infection is the highest, with HPV52, 16, 58 as the main infection subtypes. The detection results of multiplex PCR capillary electrophoresis fragment analysis method are highly consistent with those of multiplex fluorescent quantitative PCR method, which is suitable for HPV DNA typing.

Surveillance of adverse events following immunization with combined attenuated live measles, mumps and rubella vaccines in Huzhou City from 2015 to 2021 / 预防医学

Objective@#To monitor the adverse events following immunization (AEFI) with combined attenuated live measles, mumps and rubella vaccines (MMR) in Huzhou City from 2015 to 2021, so as to provide insights into the implementation of the MMR immunization strategy.@*Methods@#All AEFI caused by MMR immunization in Huzhou City from 2015 to 2021 were captured from the AEFI Monitoring Information Management System of the Immunization Planning System of Chinese Disease Control and Prevention Information System, and the incidence, clinical features and epidemiological features of AEFI were analyzed descriptively.@*Results@#The reported incidence of AEFI caused by MMR immunization appeared a tendency towards a rise in Huzhou City from 2015 to 2021 (χ2trend=124.126, P<0.001). Totally 324 386 doses of MMR vaccines were immunized, and 317 cases with AEFI were reported, with an reported incidence rate of 9.77/104 doses. Following two-dose immunization, the reported incidence of AEFI caused by two-dose MMR immunization was significantly lower than by one-dose immunization (6.01/104 doses vs. 25.43/104 doses; χ2=113.692, P<0.001). The incidence rates of general reactions, abnormal reactions and coincidental events were 6.20/104 doses, 3.42/104 dose and 0.15/104 doses, respectively. Fever and allergic rash were predominant clinical manifestations of AEFI, and no vaccine quality accident, inoculation accident or psychogenic reaction were reported. There were 246 (77.60%) cases with AEFI within 24 hours following vaccination, and among children with AEFI, there were 173 boys (54.57%), and 200 children (63.09%) age ages of less than one year (63.09%). AEFI was reported in each quarter, and 99 cases (31.23%) were reported in the fourth quarter. The largest number of children with AEFI was reported in Wuxing District (78 cases, 24.61%).@*Conclusions@#The safety of MMR vaccination is high in Huzhou City. General reaction is the predominant AEFI, which mainly occurs within 24 hours following vaccination. Two-dose MMR vaccination does not increase the risk of AEFI.

Countermeasures of adverse reactions to blood donation in low-weight blood donors for the MCS+ blood cell separator UPP procedure / 中国输血杂志

【Objective】 To reduce the occurrence of adverse reactions to blood donation during platelet collection in female blood donors with low body weight and high platelet count, so as to improve the comfortableness during platelet collection and increase the proportion of repeated blood donors. 【Methods】 The control group and observation group were compared to explore the causes that may cause adverse reactions in the blood collection cycle using blood collection process program software in MCS+, and the incidence of blood donation reaction was compared and observed by increasing the times of oral administrations of calcium gluconate by 10%, increasing the number of collection cycles and reducing the peak plasma volume of the last cycle. 【Results】 After comparing the two groups, it was found that the incidence of adverse reactions in the observation group and the control group was 16.7%(3/18) and 81.2%(26/32), the proportion of repeated donors in the observation group and the control group was 77.7%(14/18) and 31.2%(10/32). 【Conclusion】 Female platelet donors with low body weight and high platelet count should be given more care during the collection process. It is suggested that giving more times of oral administrations of calcium gluconate by 10% and one more collection cycle to reduce the collection peak in each cycle, as well as the supplement of saline, which can effectively reduce the occurrence of adverse reactions to blood donation, thus improving blood donation satisfaction and increasing the proportion of repeated blood donors.

Anesthetic Management and Outcomes of Endovascular Treatment of Basilar Artery Occlusion: Results From the ATTENTION Registry / 대한뇌졸중학회지

Background@#and Purpose To examine the clinical and safety outcomes after endovascular treatment (EVT) for acute basilar artery occlusion (BAO) with different anesthetic modalities. @*Methods@#This was a retrospective analysis using data from the Endovascular Treatment for Acute Basilar Artery Occlusion (ATTENTION) registry. Patients were divided into two groups defined by anesthetic modality performed during EVT: general anesthesia (GA) or non-general anesthesia (non-GA). The association between anesthetic management and clinical outcomes was evaluated in a propensity score matched (PSM) cohort and an inverse probability of treatment weighting (IPTW) cohort to adjust for imbalances between the two groups. @*Results@#Our analytic sample included 1,672 patients from 48 centers. The anesthetic modality was GA in 769 (46.0%) and non-GA in 903 (54.0%) patients. In our primary analysis with the PSM-based cohort, non-GA was comparable to GA concerning the primary outcome (adjusted common odds ratio [acOR], 1.01; 95% confidence interval [CI], 0.82 to 1.25; P=0.91). Mortality at 90 days was 38.4% in the GA group and 35.8% in the non-GA group (adjusted risk ratio, 0.95; 95% CI, 0.83 to 1.08; P=0.44). In our secondary analysis with the IPTW-based cohort, the anesthetic modality was significantly associated with the distribution of modified Rankin Scale at 90 days (acOR: 1.45 [95% CI: 1.20 to 1.75]). @*Conclusion@#In this nationally-representative observational study, acute ischemic stroke patients due to BAO undergoing EVT without GA had similar clinical and safety outcomes compared with patients treated with GA. These findings provide the basis for large-scale randomized controlled trials to test whether anesthetic management provides meaningful clinical effects for patients undergoing EVT.

Herbal-moxa plaster for diarrhea type irritable bowel syndrome of spleen and kidney yang deficiency: a randomized controlled trial / 中国针灸

OBJECTIVE@#To compare the clinical efficacy between herbal-moxa plaster and moxa-box moxibustion for diarrhea type irritable bowel syndrome (IBS-D) of spleen and kidney yang deficiency.@*METHODS@#Eighty patients with IBS-D of spleen and kidney yang deficiency were randomly divided into a herbal-moxa plaster group and a moxa-box moxibustion group, 40 cases in each group. The patients in the two groups were treated with conventional acupuncture at Baihui (GV 20), Yintang (GV 24+), Zhongwan (CV 12) and bilateral Tianshu (ST 25), Yinlingquan (SP 9), and Taixi (KI 3), etc. In addition, the patients in the herbal-moxa plaster group were treated with herbal-moxa plaster (Wenyang Fuzheng ointment, composed of prepared monkshood, prepared evodia rutaecarpa, dried ginger, cinnamon, etc.) at Shenque (CV 8), Guanyuan (CV 4), Zhongwan (CV 12) and bilateral Tianshu (ST 25), Shenshu (BL 23) and Shangjuxu (ST 37); the patients in the moxa-box moxibustion group were treated with moxa-box moxibustion at the same acupoints as the herbal-moxa plaster group. The acupuncture-moxibustion treatment was provided once every other day for 4 weeks (14 treatments). Before and after treatment, the scores of clinical symptom of TCM, irritable bowel syndrome (IBS) symptom severity scale (IBS-SSS) and IBS quality of life scale (IBS-QOL) were compared between the two groups, and the clinical efficacy was evaluated.@*RESULTS@#Compared with those before treatment, each item scores and total scores of clinical symptom of TCM, and IBS-SSS scores in the two groups were reduced after treatment (P<0.05). The abdominal bloating score, stool frequency score and total score of clinical symptom of TCM as well as IBS-SSS score in the herbal-moxa plaster group were lower than those in the moxa-box moxibustion group (P<0.05). Compared with those before treatment, the IBS-QOL scores in the two groups were increased after treatment (P<0.05), and the IBS-QOL score in the herbal-moxa plaster group was higher than that in the moxa-box moxibustion group (P<0.05). The total effective rate was 92.5% (37/40) in the herbal-moxa plaster group, which was higher than 85.0% (34/40) in the moxa-box moxibustion group (P<0.05).@*CONCLUSION@#On the basis of conventional acupuncture treatment, herbal-moxa plaster could effectively improve the clinical symptoms and quality of life in IBS-D patients of spleen and kidney yang deficiency, and its efficacy is superior to that of moxa-box moxibustion.
