Iron deficiency(ID)and ID anemia(IDA)pose significant public health concerns in China.Although iron sucrose(IS)treatment is well-established in the country,ferric carboxymaltose(FCM)offers the advantage of higher doses and fewer infusions.This open label,randomized,controlled,non-inferiority trial was conducted at multiple sites in China to compare the outcomes of FCM(maximum of 2 doses,500 or 1000 mg iron)and IS(up to 11 infusions,200 mg iron)treatments in subjects with IDA.The primary endpoint was the achievement of hemoglobin(Hb)response(an increase of⩾2 g/dL from baseline)within 8 weeks,whereas secondary endpoints included changes in Hb,transferrin saturation,and serum ferritin levels.Among the 371 randomized subjects,a similar percentage of subjects treated with FCM and IS achieved Hb-response(FCM 99.4%,IS 98.3%),thereby confirming the non-inferiority of FCM compared with IS(difference 1.12(−2.15,4.71;95%confidence interval(CI))).Furthermore,a significantly higher proportion of FCM-treated subjects achieved early Hb-response at Week 2(FCM 85.2%,IS 73.2%;difference 12.1(3.31,20.65;95%CI)).Additionally,the increase in TSAT and serum ferritin levels from baseline was significantly greater at all time points for FCM-treated subjects.The safety profiles of FCM and IS were comparable,with the exception of transient hypophosphatemia and pyrexia,which are consistent with FCM’s known safety profile.In conclusion,FCM proves to be an efficacious treatment for IDA,providing faster Hb-response and correction of ID with fewer administrations than IS.

Effect of nitrile butadiene rubber hardness on the sealing characteristics of hydraulic O-ring rod seals

引用

Journal of Zhejiang University-Science A(Applied Physics & Engineering) 2024年第1期25卷 63-78页

作者： Xiaoxuan LI Bingqing WANG Xudong PENG Yuntang LI Xiaolu LI Yuan CHEN jie jin College of Quality and Safety Engineering China Jiliang UniversityHangzhou310018China College of Mechanical and Electrical Engineering China Jiliang UniversityHangzhou310018China College of Mechanical Engineering Zhejiang University of TechnologyHangzhou310023China

The nitrile butadiene rubber(NBR)hardness effect on the sealing characteristics of hydraulic O-ring rod seals is analyzed based on a mixed lubrication elastohydrodynamic model.Parameterized studies are conducted to reveal the mechanism of the influence of rubber hardness on the static and dynamic behavior of seals.The optimized selections of rubber hardness are then investigated under different conditions.Results show that the low hardness seal is prone to stress concentration due to the extrusion effect under high pressure conditions;it is also more prone to leaking.A high hardness seal can better prevent leakage by reducing film thickness but it will cause large frictional power loss and increase the probability of wear failure.The choice of low hardness is recommended to reduce friction with the premise that leakage requirements are met.

In this paper,finite element method is used to calculate the static performance of gas journal bearing,in which rotation speed term is introduced into the stiffness matrix of linear triangular element to realize the performance calculation of the bearing with rotation speed.The results indicate that the average gas film thicknesses corresponding to the maximum load capac-ity and stiffness,and the minimum attitude angle increase with the growth of orifice diameter.Load capacity and stiffness significantly improved with the increase of rotation speed,eccentricity ratio and supply pressure when the bearing has thin average gas film thickness.Attitude angle increases with the growth of rotation speed,while the growth rate slows down or even decreases at high speed.The most effective way of reducing attitude angle is to increase supply pressure.It can be found that rotation speed affects attitude angle through changing gas pressure difference between two orifices,while other parameters have the same effect by changing gas pressure at orifice outlet.

BACKGROUND Acute lower gastrointestinal bleeding(LGIB)is a common occurrence in clinical practice.However,appendiceal bleeding is an extremely rare condition that can easily be overlooked and misdiagnosed.The preoperative detection of appen-diceal bleeding often poses challenges due to the lack of related guidelines and consensus,resulting in controversial treatment approaches.CASE SUMMARY We presented a case of a 33-year-old female who complained of hematochezia that had lasted for 1 d.Colonoscopy revealed continuous bleeding in the appen-diceal orifice.A laparoscopic appendectomy was performed immediately,and a pulsating blood vessel was observed in the mesangium of the appendix,accor-dingly,active bleeding into the appendicular lumen was considered.Pathological examination revealed numerous hyperplastic vessels in the appendiceal mucosa and dilated capillary vessels.CONCLUSION The preoperative detection of appendiceal bleeding is often challenging,colo-noscopy is extremely important,bowel preparation is not routinely recommend-ed for patients with acute LGIB or only low-dose bowel preparation is recom-mended.Laparoscopic appendectomy is the most appropriate treatment for appendiceal bleeding.

Rare Metals 2024年第6期43卷 2730-2738页

作者： jin-Hang Xue Qiu-Hong Sun Cheng Han Yuan-Dong Yang Shao-jie Xu Qi-Peng Li jin-jie Qian College of Life and Environmental Science Wenzhou University College of Chemistry and Materials Engineering Wenzhou University College of Chemistry and Chemical Engineering Zhaotong University

Meeting the continuous glucose monitoring requirements of individuals necessitates the research and development of sensors with high sensitivity and stability.In this study,a straightforward strategy was proposed for synthesizing ultra-thin oxygen-rich graphitized carbon nanosheets（denoted as GCS-O）.These nanosheets are obtained by calcining a topologically two-dimensional indium-based coordination polymer.Subsequently,the growth of FeNi Prussian blue analogue（PBA） on GCS-O effectively introduces active sites and increases the nitrogen content within the carbonaceous matrix.The resulting FeNi-PBA/GCS-O composite exhibits excellent glucose sensing performance with a broad linear range of 1 to 1300μmol·L-1.Meanwhile,it also achieves a high sensitivity of 2496 μA·mmol-1·L·cm-2,a limit of detection of 100nmol·L-1（S/N=3）,and commendable long-term durability.The relatively simple synthesis process,exceptional sensitivity,and satisfactory electrochemical sensing performance of FeNi-PBA/GCS-O open up new directions for biosensor applications.

World Journal of Clinical Cases 2024年第11期12卷 1947-1953页

作者： Yang Xiong jin Li Han-jie Yang Department of Urology Pingxiang People’s HospitalPingxiang 337000Jiangxi ProvinceChina

BACKGROUND Schwannomas are rare peripheral neural myelin sheath tumors that originate from Schwann cells.Of the different types of schwannomas,pelvic sciatic nerve schwannoma is extremely rare.Definite preoperative diagnosis of pelvic schwannomas is difficult,and surgical resection is the gold standard for its definite diagnosis and treatment.CASE SUMMARY We present a case of pelvic schwannoma arising from the sciatic nerve that was detected in a 40-year-old man who underwent computed tomography for intermittent right lower back pain caused exclusively by a right ureteral calculus.Subsequently,successful transperitoneal laparoscopic surgery was performed for the intact removal of the stone and en bloc resection of the schwannoma.The total operative time was 125 min,and the estimated blood loss was inconspicuous.The surgical procedure was uneventful.The patient was discharged on postoperative day 5 with the simultaneous removal of the urinary catheter.However,the patient presented with motor and sensory disorders of the right lower limb,caused by partial damage to the right sciatic nerve.No tumor recurrence was observed at the postoperative appointment.CONCLUSION Histopathological examination of the specimen confirmed the diagnosis of a schwannoma.Thus,laparoscopic surgery is safe and feasible for concomitant extirpation of pelvic schwannomas and other pelvic and abdominal diseases that require surgical treatment.

作者： jing jin Xinyao Wang Yang Hu Zhuang Zhang Hongbo Liu jie Yin Pinxian Xi College of Chemistry and Chemical Engineering Frontiers Science Center for Rare IsotopesState Key Laboratory of Applied Organic ChemistryLanzhou UniversityLanzhou 730000People’s Republic of China

Ef fective and robust catalyst is the core of water splitting to produce hydrogen.Here, we report an anionic etching method to tailor the sulfur vacancy(VS) of NiS_(2) to further enhance the electrocatalytic performance for hydrogen evolution reaction(HER). With the VS concentration change from 2.4% to 8.5%, the H* adsorption strength on S sites changed and NiS_(2)-VS 5.9% shows the most optimized H* adsorption for HER with an ultralow onset potential(68 m V) and has long-term stability for 100 h in 1 M KOH media. In situ attenuated-total-reflection Fourier transform infrared spectroscopy(ATR-FTIRS) measurements are usually used to monitor the adsorption of intermediates. The S-H* peak of the Ni S_(2)-VS 5.9% appears at a very low voltage, which is favorable for the HER in alkaline media. Density functional theory calculations also demonstrate the Ni S_(2)-VS 5.9% has the optimal |ΔG^(H*)| of 0.17 e V. This work offers a simple and promising pathway to enhance catalytic activity via precise vacancies strategy.
