Objective To observe the clinical effect of Ziyin Qingshenyin on lupus nephritis(LN)with Yin deficiency and internal heat syndrome.Methods Sixty patients diagnosed with LN were selected from June 2020 to May 2022 from our hospital as research partici-pants and randomly divided into control group(n=30)and combination group(n=30).The control and combination groups were adminis-tered conventional Western medicine and conventional Western medicine with Ziyin Qingshenyin,respectively.Clinical efficacy,traditional Chinese medicine(TCM)syndrome score and efficacy,renal function index[serum albumin(ALB),serum creatinine(sCr),hemoglobin(Hb),blood urea nitrogen(BUN),and 24 h urinary protein quantitation(24 h Upro)],immunological indicators[complement C3,com-plement C4,immunoglobulin(Ig)M,IgG,and IgA],inflammatoryindicators[C-reactive protein(CRP)and erythrocyte sedimentation rate(ESR)],disease activity score of systemic lupus erythematosus(SLEDAI),and safety were determined.Results The total effective rate(86.67%,83.33%)of the combination group was higher than that of the control group(63.33%,60.00%)(P<0.05).Following treatment,the five syndrome scores of heat,sore throat,night sweats,and macula in combination group were lower than those in the control group(P<0.05).After treatment,24 h Upro,BUN,sCr,IgM,IgG,IgA,CRP,ESR,and SLEDAI scores in the combination group were lower than those in control group,while ALB,Hb,complement C3,and complement C4 were higher than those in the control group(P<0.05).There was no significant difference in the incidence of adverse reactions between the two groups(P>0.05).Conclusion The Ziyin Qingshen-yin treatment has notable effects on LN with Yin deficiency and internal heat syndrome,which can improve renal function and immunolog-ical indexes,reduce inflammatory factors,and contribute to disease control.
RESUMEN
Primary hypertrophic osteoarthropathy(PHO) is a rare disease also known as pachydermoperiostosis. We reported a painless case whose diagnosis was confirmed by genetic test. A 24-year-old male presented a series of symptoms that first began at 14. He suffered from progressive clubbed-fingers accompanied by swelling of the wrist and ankle joints. Facial skin concentric thickening and alar nose broadening appeared simultaneously and increased progressively. He was also prone to acne and hyperhidrosis. X-rays showed thickening of the metacarpal and phalangeal bones, as well as symmetrical periosteal ossification of both the tibia and fibula. Clinical diagnosis of PHO is difficult because of the variable features. With acromegaly excluded, the diagnosis was confirmed by a genetic test. Whole exome sequencing revealed a heterozygous SLCO2A1 c.611C > T(p.Ser204Lue) and SLCO2A1 c.1602C > A(p.Asn534Lys) mutation from each parent. It suggests that primary hypertrophic osteoarthropathy should be considered for young limb hypertrophic patients especially when periosteal thickening signs were showed in X-ray. A confirmatory diagnosis can be made through the genetic test.
RESUMEN
Acute myeloid leukemia (AML) is a malignant clonal disease of hematopoietic stem cells, characterized by the proliferation of abnormal primordial cells of myeloid origin in bone marrow, blood and other tissues. At present, the standard induction therapy for AML mainly includes “3+7” standard treatment(anthracycline combined with cytarabine), allogeneic hematopoietic stem cell transplantation (Allo-HSCT) and targeted drug therapy. However, AML cells usually express high levels of P-glycoprotein, which mediates the efflux of chemotherapeutic drugs, which makes AML cells resistant to chemotherapy, resulting in many patients who are not sensitive to chemotherapy or relapse after complete remission. And some patients can not tolerate intensive therapy or lack of donors and can not use Allo-HSCT therapy. Therefore, it is of great clinical significance to find new drugs to improve the efficacy of AML patients. Epigenetic disorders play a key role in the pathogenesis of many diseases, especially cancer. Studies have shown that most AML patients have epigenetic regulatory gene mutations, such as DNMT3A, IDH and TET2, and these mutations are potentially reversible, which has become one of the therapeutic targets of AML. Histone deacetylase inhibitors (HDACi) can regulate the balance between histone acetylation and deacetylation, change the expression of proto-oncogenes or tumor suppressor genes that control cancer progression from epigenetics, and play an important role in many kinds of tumor therapy. At present, HDACi has shown the ability to induce differentiation, cell cycle arrest and apoptosis of AML cells. The mechanism may be mainly related to HDACi inducing chromatin conformation opening of tumor suppressor gene by inhibiting HDAC activity, promoting oncogene damage and preventing oncogene fusion protein from recruiting HDAC. Although the preclinical outcome of HDACi is promising, it is not as effective as the conventional therapy of AML. However, the combination strategy with various anticancer drugs is in clinical trials, showing significant anti-AML activity, improving efficacy through key targeting pathways in a typical synergistic or additive way, increasing AML sensitivity to chemotherapy, reducing tumor growth and metastasis potential, inhibiting cell mitotic activity, inducing cell apoptosis, regulating bone marrow microenvironment, which provides a good choice for the treatment of AML. Especially for those AML patients who are not suitable for intensive therapy and drug resistance to chemotherapy. This review introduces the relationship between HDAC and cancer; the classification of HDAC and its function in AML; the correlation between HDAC and AML; the clinical application of five types of HDACi; preclinical research results and clinical application progress of six kinds of HDACi in AML, such as Vrinota, Belinostat, Panobinostat, Valproic acid, Entinostat, and Chidamide, the mechanism of HDACi combined with other anticancer drugs in AML indicates that the current HDACi is mainly aimed at various subtypes of pan-HDAC inhibitors, with obvious side effects, such as fatigue, thrombocytopenia, nausea, vomiting, diarrhea. In recent years, the next generation of HDACi is mainly focused on the selectivity of analogues or isomers. Finding the best combination of HDACi and other drugs and the best timing of administration to balance the efficacy and adverse reactions is a major challenge in the treatment of AML, and the continued development of selective HDACi with less side effects and more accurate location is the key point for the development of this drug in the future. It is expected to provide reference for clinical treatment of AML.

RESUMEN
Neural recording electrodes enable the acquisition and collection of electrical signals from neu-rons,and these recorded neural electrical signals are an important means of understanding neuronal activity.As a major component of the brain-machine interface,neu-ral recording electrodes serve as a bridge between the nervous system and external devices.The extracted information can be used to understand the state of the brain and acts as a feedback signal to regulate external devices,thus providing important information for the clini-cal treatment of neurological diseases.Moreover,the electrodes can be used as a vehicle for drug injection to directly treat diseases.Since the time that Strumwas-ser used microwires to achieve long-term recordings of neural activity in hibernating squirrels,implantable elec-trode technology has gradually improved over three gen-erations of development,and progress has been made in improving the biocompatibility,mechanical performance(size,shape,density,etc.),and signal-to-noise ratio.Implantable neural recording electrodes can acquire sig-nals from cortical and deep neural clusters,with the advantages of high signal-to-noise ratio,information con-tent,and spatial/temporal resolution.However,there is still a need to improve the structure and performance of these electrodes;for example,their high invasiveness and lack of biocompatibility pose technical difficulties in the process of translation to the clinic.This paper reviews the basic requirements for electrodes,main recording methods and signal types,common types of implant-able neural recording electrodes,and their challenges and future development directions.With the continuous development of electrode materials,equipment,systems,and neurotechnology,it should be possible to apply neu-ral recording electrodes in clinical practice,to promote safe and efficient treatment of human diseases.
RESUMEN
This article reported a case of fetal giant hepatic hemangioma with cardiomegaly managed with intrauterine treatment. At 23 weeks of gestation, the patient was referred to Guangdong Women and Children Hospital due to abnormal abdominal echogenicity of the fetus, which was suspected to be a hepatic hemangioma or a hepatic arteriovenous fistula. The prenatal ultrasound at 26 weeks of gestation revealed an enlarged fetal hepatic hemangioma of 45 mm×35 mm×42 mm and an enlarged heart (cardiothoracic area ratio of 0.50). So, with the patient's informed consent, the fetus was treated with intrauterine administration of propranolol and dexamethasone and closely monitored by ultrasound. The volume of the lump still increased at the beginning of the medication, but started to shrink in the 7th week. Besides, the fetal cardiac load was reduced and the condition was controlled. The patient delivered at 37 weeks of gestation. The baby received a CT examination on the fourth day after birth which revealed an abdominal mass of 40 mm×30 mm×44 mm requiring no treatment, and no abnormalities were reported during a one-year follow-up.
RESUMEN
The multi-campus mode is an important way to give full play to the advantages of public hospitals and promote the expansion of high-quality medical resources and balanced regional layout. The authors summarized the practical experience of the Second Affiliated Hospital Zhejiang University School of Medicine in promoting multi-campus cultural integration, including vertical dimensional initiatives including raising cultural construction to a strategic level, improving the working mechanism of cultural construction, and building a distinctive cultural identity system; horizontal dimensional initiatives including creating equal status and intergroup cooperation conducive to cultural integration, building a variety of forms of the main cultural communication platform, and building a unified and diverse cross-campus communication bridge. Through cultural integration, the internal cohesion of the hospital was enhanced and the influence of the hospital brand was improved. The authors suggested that cultural integration should always be based on the principle of " seeking common ground while preserving minor differences" , focusing on the construction of systems and standards, and focusing on the construction of communication platforms.
RESUMEN
OBJECTIVE@#This study aims to estimate the cost-effectiveness of the combined chemotherapy regimen containing Bedaquiline (BR) and the conventional treatment regimen (CR, not containing Bedaquiline) for the treatment of adults with multidrug-resistant tuberculosis (MDR-TB) in China.@*METHODS@#A combination of a decision tree and a Markov model was developed to estimate the cost and effects of MDR patients in BR and CR within ten years. The model parameter data were synthesized from the literature, the national TB surveillance information system, and consultation with experts. The incremental cost-effectiveness ratio (ICER) of BR vs. CR was determined.@*RESULTS@#BR ( vs. CR) had a higher sputum culture conversion rate and cure rate and prevented many premature deaths (decreased by 12.8%), thereby obtaining more quality-adjusted life years (QALYs) (increased by 2.31 years). The per capita cost in BR was as high as 138,000 yuan, roughly double that of CR. The ICER for BR was 33,700 yuan/QALY, which was lower than China's 1× per capita Gross Domestic Product (GDP) in 2020 (72,400 yuan).@*CONCLUSION@#BR is shown to be cost effective. When the unit price of Bedaquiline reaches or falls below 57.21 yuan per unit, BR is expected to be the dominant strategy in China over CR.

RESUMEN
Nail-patella syndrome (NPS) is a hereditary rare disease that can involve fingernail, patella, elbow, and iliac bones. In this article, we report a case of a girl-9 and 1 quarter years old who had asthmatic contractures in both elbows, thumbnail hypoplasia in both hands, patellar dislocation of both knees, iliac angle protrusion of both sides, and scoliosis. Whole exome sequencing suggests the presence of a LMX1B NM_002316.4:c.706G > C(p.Ala236Pro) mutation. NPS is an autosomal dominant disease associated with gene mutation of LMX1B, which can be diagnosed by combining the patient′s clinical manifestations and genetic results. The treatment now only targets on symptoms, relieving the localized severe lesion but not cure right now.
RESUMEN
Objective: Analysis and investigation of pathogenic characteristics of polymyxin-and carbapenem-resistant Klebsiella pneumoniae (PR-CRKP). Methods: A total of 23 PR-CRKP strains isolated from clinical specimens from the General Hospital of Southern Theater Command from March 2019 to July 2021 were retrospectively collected, Whole-genome sequencing was performed on 23 PR-CRKP strains, resistance genes were identified by comparison of the CARD and the ResFinder database, high-resolution typing of PR-CRKP strains was analyzed by core genomic multilocus sequencing (cgMLST) and single nucleotide polymorphism (SNP); polymyxin resistance genes were determined by PCR and sequencing. Results: All PR-CRKP strains were KPC-2 producing ST11 types. cgMLST results showed that the evolutionary distance between the PR-CRKP strains and Klebsiella pneumoniae in mainland China was 66.44 on average, which is more closely related than foreign strains; the 23 PR-CRKP strains were divided into 3 main subclusters based on SNP phylogenetic trees, with some aggregation among Clade 2-1 in the isolation department and date. The two-component negative regulatory gene mgrB has seven mutation types including point mutations, different insertion fragments and different insertion positions. Conclusion: The close affinity of PR-CRKP strains indicate the possibility of nosocomial clonal transmission and the need to strengthen surveillance of PR-CRKP strains to prevent epidemic transmission of PR-CRKP.

This study aims to explore the influence of Polygonati Rhizoma on the pyroptosis in the rat model of diabetic macroangiopathy via the NOD-like receptor thermal protein domain associated protein 3(NLRP3)/cysteinyl aspartate specific proteinase-1(caspase-1)/gasdermin D(GSDMD) pathway. The rat model of diabetes was established by intraperitoneal injection of streptozotocin(STZ) combined with a high-fat, high-sugar diet. The blood glucose meter, fully automated biochemical analyzer, hematoxylin-eosin(HE) staining, enzyme-linked immunosorbent assay, immunofluorescence, immunohistochemistry, and Western blot were employed to measure blood glucose levels, lipid levels, vascular thickness, inflammatory cytokine levels, and expression levels of pyroptosis-related proteins. The mechanism of pharmacological interventions against the injury in the context of diabetes was thus explored. The results demonstrated the successful establishment of the model of diabetes. Compared with the control group, the model group showed elevated levels of fasting blood glucose, total cholesterol(TC), triglycerides(TG) and low-density lipoprotein cholesterol(LDL-c), lowered level of high-density lipoprotein cholesterol(HDL-c), thickened vascular intima, and elevated serum and aorta levels of tumor necrosis factor-α(TNF-α), interleukin-1β(IL-1β) and interleukin-18(IL-18). Moreover, the model group showed increased NLRP3 inflammasomes and up-regulated levels of caspase-1 and GSDMD in aortic vascular cells. Polygonati Rhizoma intervention reduced blood glucose and lipid levels, inhibited vascular thickening, lowered the levels of TNF-α, IL-1β, IL-18 in the serum and aorta, attenuated NLRP3 inflammasome expression, and down-regulated the expression levels of caspase-1 and GSDMD, compared with the model group. In summary, Polygonati Rhizoma can slow down the progression of diabetic macroangiopathy by inhibiting pyroptosis and alleviating local vascular inflammation.

OBJECTIVE@#To investigate the effectiveness of arthroscopic multi-point fixation with anchor and suture in the treatment of tibial insertion avulsion fracture of anterior cruciate ligament (ACL) involving the anterior root of lateral meniscus (LM).@*METHODS@#A retrospective analysis was conducted on the clinical data of 28 patients with tibial insertion avulsion fracture of ACL involving the anterior root of LM who were treated with arthroscopic multi-point fixation with anchor and suture between October 2017 and January 2023. There were 12 males and 16 females with the mean age of 26 years (range, 13-57 years). There were 20 cases of sports injury and 8 cases of traffic accident injury. In 2 cases of old fracture, the time from injury to operation was 45 days and 90 days, respectively; in 26 cases of fresh fracture, the time from injury to operation was 3-20 days (mean, 6.7 days). According to the Meyers-McKeever classification, there were 4 cases of type Ⅱ, 11 cases of type Ⅲ, and 13 cases of type Ⅳ. The preoperative Lysholm knee function score was 42.1±9.0, the International Knee Documentation Committee (IKDC) score was 40.0±7.3, and the Tegner score was 0.7±0.7.@*RESULTS@#All operations were successfully completed, and the incisions healed by first intention. All the 28 patients were followed up 5-60 months (mean, 20.4 months). During the follow-up, there was nocomplication such as infection, vascular or nerve injury, loosening or breakage of internal fixator, or stiffness of knee joint. Postoperative X-ray films showed satisfactory fracture reduction and firm fixation. All fractures healed clinically, and the healing time was 8-16 weeks (mean, 10.3 weeks). At last follow-up, Lachman test and anterior drawer test were negative. At last follow-up, Lysholm knee function score was 92.4±5.5, IKDC score was 91.6±4.4, and Tegner score was 5.2±1.1, which significantly improved when compared with preoperative scores ( t=-22.899, P<0.001; t=-29.870, P<0.001; t=-19.979, P<0.001).@*CONCLUSION@#Multi-point fixation with anchor and suture in the treatment of tibial insertion avulsion fracture of ACL involving the anterior root of LM can not only fix the LM, but also effectively reduce and fix the avulsion fracture, which can obtain good effectiveness.

Serum levels of IL-6 and TNF-α in the three groups at 7 and 15 days after surgery were reduced compared with those at 2 days after surgery ( P<0.01), and with the extension of time, the levels of serum IL-6 and TNF-α in the three groups decreased from the aspects of time-point effect ( F=69.36, 38.76) and between-group effect ( F=21.81, 13.50) ( P<0.01), and there was an interaction effect between the decrease degree and treatment method ( F=28.46, 23.34, P<0.01). The total effective rate was 100.0% (40/40) in combined treatment group, 80.0% (32/40) in external TCM application group and 87.2% (34/39) in oral TCM administration group ( H=8.44, P=0.015). Conclusion:The combination of Compound Huangbai Liquid coating and Xiaochuang Mixture can reduce perianal secretions, improve granulation morphology, alleviate surrounding tissue edema and wound pain, promote wound healing, and reduce inflammatory response of patients with perianal abscess surgery.
RESUMEN
Objective To observe the inhibitory effect of Tirofiban on different shear-induced platelet aggregation, and to provide medication suggestions for the treatment of thrombosis in different hemodynamic environment. Methods Polydimethylsiloxane ( PDMS)-glass microchannel chips were fabricated by soft lithography. The whole blood of healthy volunteers anticoagulated with sodium citrate was collected and incubated with different concentrations of Tirofiban in vitro. The blood flowed through the straight microchannel or channel with 80% narrow for 150 seconds at the speed of 11 μL/ min and 52 μL/ min, respectively. The wall shear stress rates in straight channel at 11 μL/ min and 52 μL/ min were 300 s-1 and 1 500 s-1, respectively. The maximum wall shear rates in the channel with 80% occlusion at 11 μL/ min and 52 μL/ min were 1 600 s-1 and 7 500 s-1, respectively. The adhesion and aggregation images of fluorescent labeled platelets on glass surface were photographed with the microscope, and the fluorescent images were analyzed with Image J. The platelet surface coverage ratio was used as a quantitative index of platelet aggregation behavior, and the IC50 of Tirofiban for platelet inhibition was calculated under different shear rates. Flow cytometry was used to detect the platelet activation index (CD62P, PAC-1) in the whole blood at 52 μL/ min in channel with 80% occlusion. Results Tirofiban inhibited platelet aggregation in a dose-dependent manner, and the inhibitory effect was related to the shear rate. Under the shear rates of 11 μL/ min and 52 μL/ min, the aggregation was almost completely inhibited when the concentration in straight channel reached 100 nmol / L. When the concentration in channels with 80% occlusion reached 1 μmol / L, the aggregation was almost completely inhibited. IC50 values at 11 μL/ min and 52 μL/ min in straight channel were 2. 3 nmol / L and 0. 5 nmol / L, respectively. IC50 values at 11 μL/ min and 52 μL/ min in channels with 80% occlusion were 20. 73 nmol / L and 4. 5 nmol / L. Pathologically high shearforce induced an increase in platelet activation, which could be inhibited by Tirofiban. Conclusions Tirofiban can effectively inhibit shear-induced platelet aggregation, and different concentrations of Tirofiban should be given according to the thrombus formed in different shear force environment in clinic practice
RESUMEN
ObjectiveThe fractional flow reserve (FFR) computed from coronary computed tomographic (CT) angiograms makes it possible to noninvasively assess coronary artery disease, but the impact of plaque on FFR derived from computed tomography angiography (CTA) is still unknown. The study used invasive FFR as the reference standard to analyze the impact of plaque on coronary computed tomography angiography (CCTA)-based quantitative flow ratio (CT-QFR). MethodsThe retrospective study included 108 patients with suspected coronary heart disease (CHD) who underwent both CCTA and FFR within 60 days. CCTA images were analyzed by the software. We obtained the CT-QFR of target vessels, perfomed the quantitative and qualitative analyses on target vascular plaques, including total plaque volume (TPV), plaque burden, calcified plaque volume (CPV), fibrous plaque volume (FPV), lipid plaque volume (LPV), and the presence or absence of high-risk plaque. ResultsAccording to the difference between CT-QFR and FFR at blood vessel level, 137 target vessels of 108 patients were divided into the overestimated group (difference>0.03, n=29), reference group (-0.03≤difference≤0.03, n=88) and underestimated group (difference<-0.03, n=20). The underestimated group (14.81mm3) presented higher LPV than overestimated group (1.97mm3, P < 0.05). There was a negative correlation between LPV and the difference (P<0.05). ConclusionsWhen CT-QFR is used to estimate hemodynamics of coronary artery stenosis, the presence of lipid plaque may underestimate the virtual FFR.
