Refractory lipoatrophy treated with autologous whole blood injection:A case report

BACKGROUND Intramuscular corticosteroid injection may cause adverse effects such as dermal and/or subcutaneous atrophy,alopecia,hypopigmentation,and hyperpigmentation.Although cutaneous atrophy can spontaneously resolve,several treatment options have been suggested for this condition.CASE SUMMARY In this paper,we report a case of corticosteroid injection induced lipoatrophy treated with autologous whole blood(AWB)injection,as the condition had been unresponsive to fractional laser therapy.A 29-year-old female patient visited the dermatology clinic complaining of skin depression on her right buttock area,which had appeared six months earlier.There had been only subtle improvement at the margins after fractional CO_(2) laser treatment;therefore,after obtaining informed consent from the patient,AWB treatment was initiated.One month after the first AWB injection,the size and depth of the lesion had noticeably improved,and a slight improvement was also observed in discoloration.CONCLUSION Close observation is the initial treatment of choice for steroid induced skin atrophy;however,for patients in need of immediate cosmetic improvement,AWB injection may be a safe and cost-effective alternative.

Effect of shenfu injection on gastrointestinal microcirculation in rabbits after myocardial ischemia-reperfusion injury

AIM： To investigate the effect of shenfu injection on gastrointestinal microcirculation after myocardial ischemic-reperfusion （IR） injury in rabbits and probe into the mechanism. METHODS： Forty healthy flap-eared white rabbits were randomly divided into 4 groups： IR injury control group （group Ⅰ ）, shenfu injection 5 mL/kg per h group （group Ⅱ）, shenfu injection 10 mL/kg per h group （group Ⅲ） and shenfu injection 20 mL/kg per h group （group Ⅳ）. The four groups were treated with Lactated Ringer＇s solution, shenfu injection 5, 10, and 20 mL/ kg per h were infused intravenously 30 min before experiment respectively. The values of hemodynamics [mean arterial pressure （MAP）, heart rate （HR）, gastric intramucosal partial pressure of carbon dioxide （PCO2）, blood gas analysis and pH] were measured and compared with those before myocardial ischemia, 60 min after myocardial ischemia and 60, 90, and 180 rain after reperfusion. RESULTS： The MAP, HR and gastric intramucosal pH were （70.50 ± 4.50） kPa, （165 ± 14） beats per rain, 7.032 ± 0.024 in group Ⅰ 60 min after myocardial ischemia, which were significantly decreased compared with those before myocardial ischemia （88.50 ± 9.75 kPa, 217 ± 18 beats per rain, 7.112 ± 0.035, P 〈 0.05）. The MAP, HR and gastric intramucosal pH were significantly decreased in group Ⅰ 60, 90, and 180 min after reperfusion （61.50 ± 5.25 kPa, 133 ± 31 beats per rain, 6.997 ± 0.025） compared with those before reperfusion respectively （P 〈 0.05）, whereas the values were insignificantly different in groups Ⅱ, Ⅲ or Ⅳ after reperfusion, compared with those before reperfusion, and there were no significant differences between groups Ⅱ, Ⅲ, and Ⅳ after reperfusion. CONCLUSION： Pre-infusion of shenfu injection has a protective effect on gastrointestinal microcirculation after myocardial IR injury in rabbits, in a dose independent manner.

Methods： Thirty-four patients were ready to receive GP regimen chemotherapy for treating NSCLC disease, according to lot-drawing, they were divided into SFI pre-treatment group （18 cases） and SFI post-treatment group （ 16 cases）. SFI pre-treatment group： During the first treatment course, chemotherapy was begun with SFI 60 ml, intravenous dripping on the 3rd day, once daily, consecutively for 10 days; on the 1st day, GP regimen （GEM 1250 mg/m^2 , intravenous dripping, on the 1st and 8th day; cisplatin 70 mg/m^2 on the 2nd day; 21 days as one cycle） was carried out; in the second treatment course GP regimen was merely given to serve as the self-control. SFI post-treatment group： the medicament sequence order was reversed from that of pre-treatment group. Using dual international quality of life （QOL） scores, the effect of SFI on the patients＂ QOL was observed through randomized self pre- and post- crossover control. Results： The QOL in the 34 patients after being treated by SFI in combination with GP chemotherapy regimen in one group, and GP chemotherapy regimen alone in the other, was improved in different degrees, with significant difference （P〈0.01）; comparision of SFI combined with GP chemotherapy regimen with GP chemotherapy alone showed that QOL in patients was significantly different （P〈0.01）. Conclusion： SFI could improve QOL in patients with NSCLC who were treated with GP regimen.

Effect of Shenfu injection on ischemia-reperfusion injury of rat liver graft

BACKGROUND: It is reported that Shenfu injection (an injection prepared from traditional Chinese medicines red ginseng and aconite root) can decrease the extent of ischemia-reperfusion injury to many organs, such as the heart and kidney. We therefore investigated the effect of Shenfu injection on ischemia-reperfusion injury of rat liver graft and its mechanism. METHODS: Male Sprague Dawley (SD) rats were used as a model for isogeneic orthotopic liver transplantation. Sixty rats were randomly devided into two groups (30 in each group). The recipient was given intravenous Shenfu injection immediately before the removal of the liver in the Shenfu group and normal saline of the same volume in the control group. At 3, 6 and 24 hours after the reperfusion, blood and hepatic tissue were taken for examination. RESULTS: The levels of superoxide dismutase (SOD) and nitric oxide (NO) increased more significantly in the Shenfu group than in the control group (P <0.05). The levels of serum liver enzymes, hyaluronic acid (HA), malondialde-hyde (MDA), tumor necrosis factor-alpha(TNF-α), inter-leukin-1 (IL-1), endothelin -1 (ET-1) and liver cell apopto-sis index were lower in the Shenfu group than in the control group (P <0. 05). Microscopic examination revealed that the morphological changes of hepatic tissue were more severe in the control group than in the Shenfu group. CONCLUSIONS: Shenfu injection has protective effect on ischemia-reperfusion injury of rat liver graft. It inhibits the production of oxygen free radical and the activation of Kupffer cells, decreases apoptosis of liver cell, and improves microcirculation.

Effect of Shenfu injection on microcirculation effect index in early-and middle-stage of cardiogenic shock rats

OBJECTIVE Shenfu injection(SFI)is an effective treatment of cardiogenic shock,the pathology of the central link was microcirculation disturbance.However,whether the microcirculation status of the early-and mid-stage of cardiogenic shock has any difference is unclear.This study aimed to observe the effect of SFI on the microcirculatory disturbance in mesentery for early-and mid-stage of cardiogenic shock rat.METHODS The early-and mid-stage model of cardiogenic shock was established by ligating the ending or root of left anterior descending coronary arteries(LADCA).The rats were randomly divided into 9 groups,ie control group,early-stage model group,mid-stage model group,3 early medicated groups and 3 mid medicated groups(the dosage was 1,3.33,10 mL·kg^(-1) SFI for cardiogenic shock rats of early-and mid-stage,respectively).Parameters in mesenteric microcirculation,such as velocity of RBCs in venules,diameters of venules,the count of leukocyte adhesion and vascular permeability which calculated by FITC-dextran leakage were observed through an GeneandiM2 inverted intravital microscope and high-speed video camera system.RESULTS The cardiogenic shock induced by ligating the LADCA resulted in a number of responses in microcirculation,including a significant increase in the counts of adhesive leukocytes,narrowing of the vascular diameter,decrease in the velocity of RBCs and dextran efflux.All of the above parameters for early-stage cardiogenic shock rats were attenuated by the treatment with SFI,especially the dosage of 10 mL·kg^(-1).While SFI had no apparent time-effect on the vascular diameter and vascular permeability in mesentery for mid-stage cardiogenic shock rats.CONCLUSION The microcirculation status of the early-and mid-stage of cardiogenic shock rats were quite different.The efficacy of early treatment with SFI was more obvious than the mid administration,which could provide experimental and theoretical basis for the patients with cardiogenic shock in an earlier time.

Shenfu injection plus vinorelbine for elderly patients with non-small cell lung cancer in promoting the quality of life: a randomized controlled clinical trial

Objective： The present study aimed to investigate the efficacy of Shenfu injection plus vinorelbine on the promotion of the quality of life （QOL） in elderly non-small cell lung cancer （NSCLC） patients. Methods： A randomized single blind trial method was used. Forty-six patients with stage IIIB-IV of HSCLC were randomly divided into experimental group and control group. In the experimental group, the patients were treated with 50 mL Shenfu injection from day 1 to 14, plus vinorelbine （NVB） 25 mg/m^2 on day 1 and 8. In the control group, the patients were only treated with NVB 25 mg/m^2 on day 1 and 8. After two cycle＇s of treatment, QOL, efficacy and toxicity were observed. Results： The QOL was enhanced in both experimental group and control group. However, the difference of KPS after treatment in the experimental group was markedly higher than in the control group （14 ± 10 vs. 8 ± 10, t = 2.116, P = 0.04）, improvement rate of QOL was better than in the control group （76.2% vs. 45.0%, χ^2 = 4.188, P = 0.041）, treatment related toxicity in the experimental group was also markedly lower than in the control group （χ^2 = 3.866, P = 0.049）, but the difference of efficacy between the two groups was not significant （14.3% vs. 15.0%, χ^2 = 0.161, P = 0.688）. Conclusion： Shenfu injection plus vinorelbine can enhance QOL in elderly NSCLC patients.

Therapeutic Effect of Shenfu Injection (参附注射液) on Secondary Aplastic Anemia of Tumor Patients after Chemotherapy

Objective: To explore the effect of Shenfu Injection (参府注射液, SFI) on the secondary aplastic anemia (AA) of tumor patients after chemotherapy (CT). Methods: The 15 cases of SFI treated group, 10 cases of control group, 25 cases of SFI + granulocyte-macrophage colony stimulating factor (GM-CSF) treated group and the group of 23 GM-CSF-treated tumor cases of secondary AA after CT were compared, with their increasing rate and the rebound speed of neutrophil, platelet, bone marrow nucleated RBC, granulocyte, and megakaryocyte all being investigated.

Exploration on the Effect and Mechanism of Shenfu Injection (参附注射液) on Resuscitation from General Anesthesia

Objective: To investigate the effect and the mechanism of Shenfu injection (SFI, ) on the resuscitation from general anesthesia . Methods: Forty patients who received selective abdominal surgery with general anesthesia for 3-4 hrs and ASA grade Ⅰ-Ⅱ were divided into two groups, the trial group and the control group, 20 patients in each group. After being sent into the postanesthesia care unit (PACU), the trial group was treated with intravenous dripping of SFI 1.0 ml/kg and the control group was treated with intravenous dripping of equal volume of normal saline. All patients were observed in double blindly manner, the self ventilation recovery time, extubation time, the time of leaving PACU and their Glasgow coma scale (GCS) were recorded and compared. 2 ml of peripheral venous blood were taken to determine the plasma β-endorphin (β-EP) content at the time points of before (T1), 5min (T2), 15min (T3) and 30 min (T4) after dripping. Results: The self ventilation recovery time, extubation time and time of leaving PACU in the trial group were all shorter than those in the control group (P<0 01), the GCS in the trial group was better than that in the control group (P<0 01). The plasma content of β-EP raised gradually along the recovering of patients consciousness, as compared with the content before dripping (T1), it showed insignificant difference at time point T2 but significant difference at T3 and T4, comparison at the corres ponding time point showed that the content at T1 and T2 were similar in the two groups (P>0 05), but at T3 and T4, the content was higher in the trial group than that in the control group respectively (P<0 01). There was insignificant difference between T1 and before treatment ( P>0 05), but significant difference was found when compared T3, T4 and before treatment (P<0 01).Conclusion: SFI could accelerate the resuscitation after general anesthesia, the mechanism may be related with its action in raising plasma β-EP level.

Cross-upgrading of biomass hydrothermal carbonization and pyrolysis for high quality blast furnace injection fuel production:Physicochemical characteristics and gasification kinetics analysis

The paper proposes a biomass cross-upgrading process that combines hydrothermal carbonization and pyrolysis to produce high-quality blast furnace injection fuel.The results showed that after upgrading,the volatile content of biochar ranged from 16.19%to 45.35%,and the alkali metal content,ash content,and specific surface area were significantly reduced.The optimal route for biochar pro-duction is hydrothermal carbonization-pyrolysis(P-HC),resulting in biochar with a higher calorific value,C=C structure,and increased graphitization degree.The apparent activation energy(E)of the sample ranges from 199.1 to 324.8 kJ/mol,with P-HC having an E of 277.8 kJ/mol,lower than that of raw biomass,primary biochar,and anthracite.This makes P-HC more suitable for blast furnace injection fuel.Additionally,the paper proposes a path for P-HC injection in blast furnaces and calculates potential environmental benefits.P-HC of-fers the highest potential for carbon emission reduction,capable of reducing emissions by 96.04 kg/t when replacing 40wt%coal injec-tion.

A Probabilistic Trust Model and Control Algorithm to Protect 6G Networks against Malicious Data Injection Attacks in Edge Computing Environments

Future 6G communications are envisioned to enable a large catalogue of pioneering applications.These will range from networked Cyber-Physical Systems to edge computing devices,establishing real-time feedback control loops critical for managing Industry 5.0 deployments,digital agriculture systems,and essential infrastructures.The provision of extensive machine-type communications through 6G will render many of these innovative systems autonomous and unsupervised.While full automation will enhance industrial efficiency significantly,it concurrently introduces new cyber risks and vulnerabilities.In particular,unattended systems are highly susceptible to trust issues:malicious nodes and false information can be easily introduced into control loops.Additionally,Denialof-Service attacks can be executed by inundating the network with valueless noise.Current anomaly detection schemes require the entire transformation of the control software to integrate new steps and can only mitigate anomalies that conform to predefined mathematical models.Solutions based on an exhaustive data collection to detect anomalies are precise but extremely slow.Standard models,with their limited understanding of mobile networks,can achieve precision rates no higher than 75%.Therefore,more general and transversal protection mechanisms are needed to detect malicious behaviors transparently.This paper introduces a probabilistic trust model and control algorithm designed to address this gap.The model determines the probability of any node to be trustworthy.Communication channels are pruned for those nodes whose probability is below a given threshold.The trust control algorithmcomprises three primary phases,which feed themodel with three different probabilities,which are weighted and combined.Initially,anomalous nodes are identified using Gaussian mixture models and clustering technologies.Next,traffic patterns are studied using digital Bessel functions and the functional scalar product.Finally,the information coherence and content are analyzed.The noise content and abnormal information sequences are detected using a Volterra filter and a bank of Finite Impulse Response filters.An experimental validation based on simulation tools and environments was carried out.Results show the proposed solution can successfully detect up to 92%of malicious data injection attacks.

Shenqi Fuzheng injection alleviates chemotherapy-induced cachexia by restoring glucocorticoid signaling in hypothalamus

Chemotherapy-induced cachexia(CIC)is a debilitating condition characterized by weight loss,muscle atrophy,and anorexia[1].While peripheral mechanisms of cachexia have been extensively studied,the involvement of the central nervous system(CNS)in CIC is often overlooked.Chemotherapeutic drugs cause stress responses and inflammation,which may impact the hypothalamus and disrupt systemic energy and neuroendocrine functions.Understanding hypothalamic roles in regulating these processes can provide insights into CIC's mechanisms and aid in developing novel therapies.

Personalized laparoscopic radical resection of gallbladder cancer by staining of the liver draining area through ICG injection into the cholecystic artery

Gallbladder cancer(GBC)is a common malignant tumor often diagnosed in advanced stages.Surgery is among the most important treatments for GBC.Radical resection of GBC involves removal of the gallbladder and the gallbladder bed[liver segments(S)4b and 5],and hepatoduodenal ligament regional lymphadenectomy.The main GBC metastasis modes are blood and lymph node metastases.The scope of resection/wedge resection or regular S4b and S5 hepatectomy for blood metastasis is a matter of debate.A variety of hepatectomy methods have been proposed for T2 stage GBC,but no consensus has been reached regarding the scope of radical resection.Currently,the liver resection range is determined by branches of the portal vein.S4b and S5 hepatectomy is determined according to the liver portal vein branch perfusion area,but the rationale for liver resection for GBC is to eliminate potential metastasis from the cystic vein reflux area to the liver.In the case described herein,we used a novel technique and theoretical framework to conduct laparoscopic radical resection of gallbladder cancer(LRRGC)facilitated by staining of the liver draining area with an indocyanine green(ICG)injection into the cholecystic artery.

Numerical Simulation of Asphaltene Precipitation and Deposition during Natural Gas and CO_(2) Injection

Asphaltene deposition is a significant problem during gas injection processes,as it can block the porous medium,the wellbore,and the involved facilities,significantly impacting reservoir productivity and ultimate oil recovery.Only a few studies have investigated the numerical modeling of this potential effect in porous media.This study focuses on asphaltene deposition due to natural gas and CO_(2) injection.Predictions of the effect of gas injection on asphaltene deposition behavior have been made using a 3D numerical simulation model.The results indicate that the injection of natural gas exacerbates asphaltene deposition,leading to a significant reduction in permeability near the injection well and throughout the reservoir.This reduction in permeability strongly affects the ability of gas toflow through the reservoir,resulting in an improvement of the displacement front.The displacement effi-ciency of the injection gas process increases by up to 1.40%when gas is injected at 5500 psi,compared to the scenario where the asphaltene model is not considered.CO_(2) injection leads to a miscible process with crude oil,extracting light and intermediate components,which intensifies asphaltene precipitation and increases the viscosity of the remaining crude oil,ultimately reducing the recovery rate.

Tofacitinib combined with local low-dose ixekizumab injection benefits those with peripheral psoriatic arthritis

Dear Editor,Treating psoriatic arthritis(PsA)is always difficult.Systemic treatments can be administered either orally or through intramuscular and intra-articular injection,including conventional synthetics,biologics and targeted synthetic disease-modifying antirheumatic drugs[1].The alternatives,topical external therapies,are not effective on joint lesions due to drug permeability issues.Drugs injected into the articular cavity are also unsuitable for small peripheral joint lesions,the most common manifestations of PsA.The limited treatment options for PsA present a challenge.

Comparative study of boron and neon injections on divertor heat fluxes using SOLPS-ITER simulations

Based on the EAST equilibrium,the effects of boron(B)and neon(Ne)injected at different locations on the target heat load,and the distributions of B and Ne particles were investigated by transport code SOLPS-ITER.It was found that the B injection was more sensitive to the injection location for heat flux control than impurity Ne.The high electron and ion densities near the inner target in the discharge with impurity B injected from over X-point(R1)led to plasma detachment only at the inner target,and the localized B ions in the cases with injection from outer target location(R2)and upstream location(R3)led to far-SOL detachment at the outer target,but not at the inner target.In contrast,for Ne,the spatial distributions of Ne ions and electrons were found to be similar in all the cases at the three injection locations,and the detached plasma was achieved at the inner target and the electron temperature was reduced at the outer target.For locations R2 and R3,impurity B showed a more pronounced effect on the heat flux at the far-SOL of the outer target.Further analysis indicated that Ne atoms came mainly from the recycling sources,whereas B atoms came mainly from injection,and that their distinct atomic distributions resulted from the difference in the ionization threshold and ionization mean free path.In addition,the radiation proportion of B in the divertor region was larger than that of Ne when the total radiation power was similar,which suggests that B has less influence on the core region.

Experimental study of the influencing factors and mechanisms of the pressure-reduction and augmented injection effect by nanoparticles in ultra-low permeability reservoirs

Nanoparticles(NPs)have gained significant attention as a functional material due to their ability to effectively enhance pressure reduction in injection processes in ultra-low permeability reservoirs.NPs are typically studied in controlled laboratory conditions,and their behavior in real-world,complex environments such as ultra-low permeability reservoirs,is not well understood due to the limited scope of their applications.This study investigates the efficacy and underlying mechanisms of NPs in decreasing injection pressure under various injection conditions(25—85℃,10—25 MPa).The results reveal that under optimal injection conditions,NPs effectively reduce injection pressure by a maximum of 22.77%in core experiment.The pressure reduction rate is found to be positively correlated with oil saturation and permeability,and negatively correlated with temperature and salinity.Furthermore,particle image velocimetry(PIV)experiments(25℃,atmospheric pressure)indicate that the pressure reduction is achieved by NPs through the reduction of wall shear resistance and wettability change.This work has important implications for the design of water injection strategies in ultra-low permeability reservoirs.
