Objective:To document any effect of combining kinesiotaping (KT) with Monitored Rehab Systems biofeedback training (MRS training) on the recovery of knee function after anterior cruciate ligament reconstruction (ACLR).Methods:Twenty-two patients after ACLR were randomly divided into an MRS group and a combined group, each of 11. In addition to conventional rehabilitation training, the MRS group had placebo taping in place during their MRS training, while the combined group had KT applied. Each training session lasted 45 minutes, with three sessions per week. Before the experiment and after 8 weeks of treatment, the affected foot support phase, impulse of each area of the affected foot′s sole, and lower limb reaction time were measured.Results:Significant improvement in the affected foot′s support phase and lower limb reaction time was documented in both groups, as well as in the average impulse percentage of the affected foot′s plantar forefoot area (F area), mid-foot area (MF area), and heel area (H area). All were significantly better in the combined group than in the MRS group, on average.Conclusion:Supplementing MRS biofeedback training with kinesiotaping can more effectively improve the knee joint functioning and postural control of patients after ACLR surgery. The combination is worthy of clinical promotion and application.

Objective:To summarize the clinical characteristics and therapeutic efficacy of central nervous system (CNS) aspergillosis.Methods:The clinical manifestations, laboratory examination, neuroimaging features, treatment and prognosis of 37 cases of CNS aspergillosis diagnosed and treated in the First Medical Center of People′s Liberation Army General Hospital from January 2000 to January 2021 were retrospectively analyzed. According to the correlation between intracranial lesions and paranasal sinus lesions, they were divided into two groups: rhino-cerebral aspergillosis (RA, n=21) group and cerebral aspergillosis (CA, n=16) group. Results:Only 16.2% (6/37) of CNS aspergillosis patients had a clear background of immunosuppression, but 35.1% (13/37) were complicated with diabetes. The most common clinical manifestations were headache (73.0%, 27/37), cranial nerve involvement (59.5%, 22/37) and fever (37.8%, 14/37). Cerebrospinal fluid characteristics included increased pressure (53.8%, 14/26), increased white blood cell count (46.7%, 14/30), decreased glucose (30.0%, 9/30), increased protein (70.0%, 21/30), and high positive results of the metagenomic next-generation sequencing (mNGS) of pathogenic microorganism (7/10). Cranial magnetic resonance imaging showed that commonly involved sites were sinus, orbital apex, posterior orbit, cavernous sinus (43.2%, 16/37) and cerebral lobes (27.0%, 10/37). Treatment options included antifungal drugs alone (64.9%, 24/37), combination of drugs and surgery (27.0%, 10/37) and surgery alone (8.1%, 3/37). Compared with the CA group, RA group had fewer males [47.6% (10/21) vs 14/16, χ2=6.34, P=0.012] and older age [(54.2±19.4) years vs (38.4±18.4) years, t=2.50, P=0.017], and was more prone to headache [85.7% (18/21) vs 9/16, χ2=4.00, P=0.046) and cranial nerve involvement [81.0% (17/21) vs 5/16, χ 2=9.31, P=0.006]. The misdiagnosis rate of these patients in the early stage was 73.0% (27/37). A total of 29 patients (85.3%, 29/34) were treated with voriconazole successively, and the course of treatment was 3.0 (0.5, 10.4) months. Compared with salvage therapy, the mortality of primary therapy was lower (4/17 vs 9/12, χ2=7.54, P=0.006). All patients were followed up to December 2021, and 17 patients died, with a mortality rate of 45.9% (17/37). Conclusions:CNS aspergillosis may have no definite immunosuppressive background. Some of CNS aspergillosis patients are complicated with diabetes, and the clinical manifestations of the disease lack specificity, with high misdiagnosis rate in the early stage, no inflammatory changes in cerebrospinal fluid, and high positive rate of mNGS for pathogenic microorganism. Early and long-term application of voriconazole can significantly reduce the mortality rate.

Although multifarious tumor-targeting modifications of nanoparticulate systems have been attempted in joint efforts by our predecessors, it remains challenging for nanomedicine to traverse physiological barriers involving blood vessels, tissues, and cell barriers to thereafter demonstrate excellent antitumor effects. To further overcome these inherent obstacles, we designed and prepared mycoplasma membrane (MM)-fused liposomes (LPs) with the goal of employing circulating neutrophils with the advantage of inflammatory cytokine-guided autonomous tumor localization to transport nanoparticles. We also utilized in vivo neutrophil activation induced by the liposomal form of the immune activator resiquimod (LPs-R848). Fused LPs preparations retained mycoplasma pathogen characteristics and achieved rapid recognition and endocytosis by activated neutrophils stimulated by LPs-R848. The enhanced neutrophil infiltration in homing of the inflammatory tumor microenvironment allowed more nanoparticles to be delivered into solid tumors. Facilitated by the formation of neutrophil extracellular traps (NETs), podophyllotoxin (POD)-loaded MM-fused LPs (MM-LPs-POD) were concomitantly released from neutrophils and subsequently engulfed by tumor cells during inflammation. MM-LPs-POD displayed superior suppression efficacy of tumor growth and lung metastasis in a 4T1 breast tumor model. Overall, such a strategy of pathogen-mimicking nanoparticles hijacking neutrophils in situ combined with enhanced neutrophil infiltration indeed elevates the potential of chemotherapeutics for tumor targeting therapy.

【Objective】 To determine the reference range of thromboelastogram(TEG) and establish a TEG feature for local population by measuring TEG parameters in healthy adults in Shenzhen comparing the difference between gender and age, and analyzing the reference data provided by reagent manufacturer. 【Methods】 A total of 916 healthy adults, aged between 19 to 59, who did their regular health checks in our hospital from September 2020 to August 2021 were selected. The TEG(from Lepu Medical Technology Co., Ltd.) was performed, and the clot reaction time(R), clot formation time(K), coagulation angle(α-Angle), maximum amplitude(MA), coagulation index(CI), fibrinolysis index LY30 and the estimated percent lysis (EPL) were analyzed. 【Results】 The reference ranges of TEG parameters, including R, K, α-Angle, MA, CI, LY30 and EPL, of 916 healthy adults from Shenzhen were 3.25~8.19 min, 0.66~3.18min, 47.70~76.56deg, 50.05~72.91mm, -4.3~3.4, 0~2.2% and 0~3%, respectively. The value of α-Angle, CI, K, LY30, MA and R didn’t all meet the given range provided by the manufacturer; some were exceeding and some inferior to. A total of 227 out of 916 individuals presented abnormal results, relative to the references, in at least one parameter, and 78 were diagnosed of abnormal coagulation based on the given reference range, with a specificity of 75.2%. 【Conclusion】 The reference range of TEG parameters of Shenzhen locals is significantly different from that provided by manufacturers. And it is imperative for local TEG laboratories to establish their own reference ranges according to age and gender groups based on local population characteristics.

In the past ten years, the research and application of microbiome has continued to increase. The microbiome has gradually become the research focus in the fields of life science, environmental science, and medicine. Meanwhile, many countries and organizations around the world are launching their own microbiome projects and conducting a multi-faceted layout, striving to gain a strategic position in this promising field. In addition, whether it is scientific research or industrial applications, there has been a climax of research and a wave of investment and financing, accordingly, products and services related to the microbiome are constantly emerging. However, due to the rapid development of microbiome sequencing and analysis related technologies and methods, the research and application from various countries have not yet unified on the standards of technology, programs, and data. Domestic industry participants also have insufficient understanding of the microbiome. New methods, technologies, and theories have not yet been fully accepted and used. In addition, some of the existing standards and guidelines are too general with poor practicality. This not only causes obstacles in the integration of scientific research data and waste of resources, but also gives related companies unfair competition opportunity. More importantly, China still lacks national standards related to the microbiome, and the national microbiome project is still in the process of preparation. In this context, the experts and practitioners of the microbiome worked together and developed the consensus of experts. It can not only guide domestic scientific research and industrial institutions to regulate the production, learning and research of the microbiome, the application can also provide reference technical basis for the relevant national functional departments, protect the scale and standardized corporate company's interests, strengthen industry self-discipline, avoid unregulated enterprises from disrupting the market, and ultimately promote the benign development of microbiome-related industries.

Objective To explore the decision-making impulsivity in patients with idiopathic generalized epilepsy.Methods 39 patients with idiopathic generalized epilepsy and 40 healthy controls completed delay discounting task.The participants were demanded to make a series of choices between two different rewards after a delayed period (a smaller sooner reward or a larger longer reward).Results The delay discount rate k was transformed to common logarithm lg (k),and lg (k)=-1.75±0.86 in IGE group was more larger than that in HC group lg (k)=-2.21±0.72(t=2.58,P=0.01).IGE group performed worse than HC group in verbal fluency test-semantic (M (P25,P75):16.00 (14.00,19.00) vs 18.00 (16.00,22.75),Z =-2.86,P＜0.01),verbal fluency test-voice (M (P25,P75):4.00 (3.00,6.00) vs 7.00 (6.00,10.00),Z =-4.26,P＜0.01) and digital span backward test (M(P25,P75):5.00(5.00,7.00) vs 6.00 (5.00,8.00),Z=-2.48,P=0.01).In addition,lg (k) had significant correlation with verbal fluency test-semantic (r=0.32,P=0.048).Conclusion IGE group prefer immediate rewards and show more impulsive than HC group in delay discounting task.IGE group has cognitive deficit in frontal lobe language function and attention function.In addition,impulsivity is correlated with frontal lobe function.

Objective To investigate the memory monitoring ability in patients with idiopathic generalized epilepsy (IGE) and explore the mechanism of the memory impairment.Methods The feeling of knowing (FOK) paradigm of episodic memory (EM) and semantic memory (SM) were established and subsequently administered in 31 patients with IGE (IGE group) and 30 healthy controls (HC group) participants who were matched in age,sex and educational level.Results Compared with HC group (feeling of knowing of episodic memory (FOK-EM) FOK accuracy (85.29± 16.84) ％;feeling of knowing of sematic memory (FOK-SM) recall (76.61± 18.66) ％),the FOK-EM FOK accuracy ((64.03± 22.10) ％) and FOK-SM recall ((53.27±26.91) ％) in IGE group were significantly decreased(t=-4.215,P＜0.01;t=-3.677,P＜0.01).The correct judgment and correct recognition of FOK-EM ((51.16±32.93) ％) and the false judgment and correct recognition ((21.07±24.38) ％) of FOK-EM in the IGE group were significantly different with the HC group (the correct judgment and correct recognition of FOK-EM:(79.34±27.26)％ and the false judgment and correct recognition of FOK-EM:(2.45±5.38) ％;t=-3.634,P＜0.01;t=4.149,P＜0.01).Most importantly,the false judgment and correct recognition of FOK-EM were correlated with the Digital Span Test,Vocabulary Fluency Test and the Stroop effect in IGE group (r=-0.309,P＜0.05;r=-0.355,P＜0.01;r=-0.354,P＜0.05;r=0.602,P＜0.01).Conclusion The results show that the IGE group made less accurate metamemory monitoring than the HC group by underestimating their memoU performance on FOK-EM,whereas the semantic metamemory monitoring is not impaired in IGE group.More importantly,the impairment of memory monitoring was correlated with the deficit of executive function,indicating that this mechanism can be an influential factor of memory disorder in IGE.It also indicates that the episodic and semantic metamemory monitoring depend on different neural networks.

Purpose To explore the CT manifestations and pathological features of pneumonia-type lung cancer, and to improve the diagnosis capability of pneumonia-type lung cancer. Materials and Methods CT and pathologic features of 33 cases of biopsy or surgical pathology confirmed pneumonia-type lung cancer patients were retrospectively analyzed and classified according to the new pulmonary adenocarcinoma classification. Results Among the 33 pneumonia-type lung cancer subjects, CT showed multiple distributions within both lungs in 22 cases, lateral lobe distribution in 9 cases, segmental distribution in 2 cases. Lung consolidation was found in all lesions, among them 21 cases appeared mainly as lower lobe consolidation, 32 cases as inflatable bronchial symptoms within the consolidation, including inflatable bronchoconstriction in 24 cases;consolidation with multiple pulmonary nodules found in 23 cases;ground glass shadowing around or distal to the consolidation found in 26 cases;combined with cysts or honeycomb lung symptom in 13 cases. Inhomogeneous mild enhancement of lung consolidation after enhancement found in 18 cases and inhomogeneous moderate enhancement in 15 cases;blood vessel branch shadow within the consolidation was visible in 21 cases. Pathology results revealed 26 cases of invasive mucinous adenocarcinoma, and 7 cases of invasive mucinous adenocarcinoma partial mixed with papillary or alveolar adenocarcinoma. Conclusion CT features of pneumonia-type lung cancer are single or multiple opacities, within which inflatable bronchial symptoms can be observed, with multiple nodules and ground glass shadowing, cysts or honeycomb symptom can also be found concomitant, the lesions expand, increase and spread to both lungs, taking its dynamic change features into consideration will also help to improve the diagnostic accuracy.

Purpose To investigate the value of three-dimensional quantitative measurement of spiral CT in evaluating tumor size and preoperative T stage in stage I non-small cell lung cancer (NSCLC). Materials and Methods The complete data of 125 patients with stage I NSCLC confirmed surgically and pathologically were compared in terms of maximum tumor diameter and T stage analysis by means of three-dimensional quantitative CT measurement, two-dimensional measurement and general pathology measurement. Results The mean maximum tumor diameter of these 125 patients measured by quantitative three-dimensional CT measurement, two-dimensional measurement and general pathology measurement were (26.21±8.14) mm, (27.03±9.90) mm and (25.60±9.31) mm, respectively. The difference in mean maximum tumor diameter by two-dimensional measurement and three-dimensional quantitative measurement was significant, and remained so when two-dimensional measurement and pathology measurement was compared (t=2.377, P<0.05;t=2.961, P<0.01), but that between three-dimensional quantitative measurement and pathology measurement was not significant (t=1.281, P>0.05). Bland-Altman analysis showed that three-dimensional quantitative measurement had higher consistency than two-dimensional measurement when compared with the gold standard pathology measurement. When three-dimensional quantitative measurement was taken to be the staging criterion, 20% results (25 cases) obtained by two-dimensional measurement proved to be inconsistent. Conclusion Compared with two-dimensional measurement, quantitative three-dimensional CT measurement can provide more accurate information in maximum tumor diameter and T stage for patients with stage I NSCLC, therefore can be applied as a more accurate criterion in preoperative staging and prognosis of stage I NSCLC.

Objective To observe the multi-slice spiral CT manifestations of cavernous transformation of the portal vein (CTPV) secondary to tumor emboli from hepatocellular carcinoma (HCC). Methods MSCT manifestations of 31 patients of HCC with tumor emboli-induced CTPV proved by operation and pathology were collected and the data were retrospectively analyzed. Results Tumor embolus was detected in both the trunk, left and right branches of PV in 23 patients, accompanied with superior mesenteric vein and/or splenic vein and inferior vena cava's tumor embolus in 4 and infiltration of gallbladder in 1 of 23 patients, as well as in the trunk and left branch in 1, and in the trunk and right branch of PV in 5 patients, accompanied with right hepatic vein and/or inferior vena cava's tumor embolus in 2 and in the portal trunk and superior mesenteric vein in 1, only in the right branch in 1 patient, respectively. Tumor emboli were isodense in plain CT scan, but enhanced with obvious degrees in arterial phase and filling defects in portal venous phase. There were collateral vessels around portal vein. Lateral branches around hilar bile duct, the open of venous plexus around fossa of gallbladder, lateral veins around gastric fundus and lesser curvature, lateral veins of lower part of esophagus and expansion of splenic vein were found in 31 (100%), 19 (61.29%), 21 (67.74%), 7 (22.58%) and 15 patients (48.38%), respectively. Conclusion Tumor emboli-induced CTPV from HCC has specific MSCT findings being helpful to the diagnosis.
