Objective To investigate the expression levels of serum miR-186-5p and miR-942-5p in patients with glioma and their clinical significance.Methods A total of 98 patients with glioma who were treated in this hospital from October 2019 to December 2021 were selected as the monitored group,and 101 healthy indi-viduals who underwent physical examinations a the same time were selected as the control group.Quantitative fluorescent PCR(qPCR)method was applied to detect the expression levels of miR-186-5p and miR-942-5p in serum,and multivariate COX regression was applied to analyze the prognostic factors of glioma patients.Re-ceiver operating characteristic(ROC)curve and area under curve(AUC)were used to analyze the diagnostic value of serum miR-186-5p and miR-942-5p in glioma.Kaplan-Meier survival curve was used to analyze the re-lationship between serum miR-186-5p and miR-942-5p expression and prognosis of patients.Results The ex-pression level of serum miR-186-5p in monitored group was lower than that in the control group(P＜0.05),and the expression level of miR-942-5p was higher than that in the control group(P＜0.05).The AUC of ser-um miR-186-5p and miR-942-5p in the diagnosis of glioma alone and in combination were 0.735,0.809 and 0.895,respectively.There were significant differences in the proportion of low miR-186-5p expression and high miR-942-5p expression in serum of patients with different preoperative Karnofsky performance status(KPS)scores,World Health Organization(WHO)grades and local infiltration(P＜0.05).The 2-year surviv-al rate of patients with high expression of miR-186-5p was higher than that of patients with low expression of miR-186-5p(x2=6.455,P=0.011).The 2-year survival rate of patients with high miR-942-5p expression was lower than that of patients with low miR-942-5p expression(x2=9.858,P=0.002).miR-186-5p was a protective factor for mortality in glioma patients(P＜0.05),while miR-942-5p was a risk factor(P＜0.05).Conclusion Serum miR-186-5p expression level decreases and miR-942-5p expression level increases in glioma patients,both of which have certain diagnostic value for the occurrence of glioma.

Objective To conduct a retrospective analysis of the correlation among bedaquiline(BDQ)plasma concentrations,relevant clinical factors,and disease prognosis.Methods In this retrospective study,22 patients diagnosed with rifampicin-resistant tuberculosis(RR-TB),multidrug-resistant tuberculosis(MDR-TB),or pre-extensively drug-resistant tuberculosis(pre-XDR-TB)were enrolled.These patients were admitted to the tuberculosis ward of our hospital between February 2022 and October 2024.All patients were administered a treatment regimen containing BDQ.The cohort comprised 6 RR-TB patients(27.27%),12 MDR-TB patients(54.55%),and 4 pre-XDR-TB patients(18.18%).Peripheral blood samples were collected 2 hours after the oral administration of Bedaquiline.The plasma concentration of Bedaquiline was measured using liquid chromatography-tandem mass spectrometry(LC-MS/MS).Spearman correlation analysis was performed using R studio software with the ggplot2 and corrplot packages.The factors included the blood concentration of bedaquiline,electrocardiogram QTcF(QT interval corrected by the Fridericia method),liver and kidney function parameters,weight,age,body mass index,sex,blood uric acid level,serum creatinine level,and other relevant indicators.Results In 22 patients treated with BDQ,the plasma concentration reached a peak after 1.5 weeks of administration,and gradually stabilized after 2 weeks.The plasma concentration was approximately 1-3 μg/mL.After 24 weeks of withdrawal of bedaquiline,patients were continued to monitor their bedaquiline concentration and found that BDQ blood concentration in peripheral blood was approximate 1 μg/mL up to 36 weeks.The serum concentration of BDQ was not correlated with age,body weight,BMI,ALT,AST,GGT,TDiL,urea,uric acid and QT interval,but correlated with sputum negative transformation and serum creatinine.The correlation analysis between serum concentration of BDQ and acid-fast staining of sputum smear showed,the difference was significant(r=0.35,P<0.05).In addition,the correlation analysis between serum BDQ concentration and serum creatinine showed,the difference was significant(r=0.34,P<0.05).The results of multiple linear regression analysis showed that BDQ blood concentration was positively correlated with Scr level,and Scr was an independent factor affecting BDQ blood concentration.20 cases(90.9%,20/22)were cured,1 case died of Covid-19 virus infection,1 case was recurrence.Conclusions Regimens containing bedaquiline seem to exhibit relatively high safety profiles and good tolerability among patients with rifampicin-resistant,multidrug-resistant,or pre-extensively drug-resistant tuberculosis,typically yielding favorable treatment outcomes.The BDQ shows a positive correlation with serum creatinine(SCr).Consequently,close surveillance of BDQ levels and renal function remains of utmost importance throughout the treatment course.

Objective To investigate the clinical significance of ANCA in the disease activity of patients with SLE.Methods A total of 1 025 SLE patients were recruited and were divided into inactive and active groups according to SLEDAI score.Demographic characteristics,clinical symptoms,autoantibodies,routine laboratory tests and renal pathology were also recorded and compared between the two groups.Results All patients were divided into inactive group(n = 750)and active group(n = 250).The occurrence of renal,pulmonary,cutaneous,arthritis manifestations were significantly higher than those of the inactive group(all P<0.05).All patients were tested for ANCA,and the most common pattern being perinuclear or p-ANCA,the percentage of p-ANCA seroposi-tive increased greatly with the increased disease activity(P<0.05).The autoantibodies were further analyzed between the two groups,25 patients had reactivity to MPO,but no patient had reactivity to PR3.Also,there were significant differences in anti-dsDNA antibody,anti-nucleosome antibody between the two groups(P<0.05).In the active group,patients with p-ANCA seropositive exhibited higher serum beta-2-microglobulin(β2-MG),titers of anti-dsDNA antibody,SLEDAI scores,lower albumin,C3,and C4 levels(P<0.05).Meanwhile,p-ANCA was associated with IL-6,which increased significantly with the increase of SLEDAI score.In addition,patients with p-ANCA seropositive had more occurrence of lupus nephritis,but it had no association with the renal pathology.Conclusion The appearance of p-ANCA in SLE patients indicated more severe disease activity status.

Objective: To setup a custom-made gait simulator, and to provide an efficient tool for biomechanics research of ankle and foot. Methods: From November 2017 to April 2018, a total of 6 fresh frozen specimens of the foot and ankle were collected. The donated specimens, free of diseases in the foot and ankle part, were from the Department of Anatomy, Shanghai Medical College of Fudan University. Donors were 3 males and 3 females, aged from 48 to 69 years old, with an average age of 58.8 years old. The nine tendons in the foot were divided into 4 bundles, including anterior group comprised of tibialis anterior (TA), extensor hallucis longus (EHL) and extensor digitorum longus (EDL). Posterior group comprised of Achilles's tendon (AT). Medial group comprised of tibialis posterior (TP), flexor hallucis longus (FHL), and flexor digitorum longus (FDL). Lateral group comprised of peroneus brevis (PB) and peroneus longus (PL). A custom-made gait simulator was set up by using four independent electro motors to actuate 4 bands of tendons in the foot and another six motors to control tibia to achieve 6 degree-freedom parallel mechanism. And a hydraulic machine was used to provide axial pressure along tibia. Gait cycle of six fresh frozen cadaver feet was reproduced using this machine, and the kinematics data of ankle movement and ground reaction force (GRF) data was collected. By comparing the data above with the normal human gait data, the simulation results were analyzed to explore the clinical usage of this machine. Results: On the sagittal plane, the ankle appeared to plantarflexion at the beginning of gait, and then turned to dorsiflexion after the max plantar flexion (about 10°) at 18% of gait cycle. At the 40% gait cycle, ankle joint was in neutral position and reached its max dorsiflexion (about 22°) at 83% gait cycle. On the coronal plane, ankle joint appeared inversion at the beginning and eversion afterwards with 10° range of change. On the horizontal plane, movement of ankle joint was small. Results showed that the first peak of vertical ground reaction force can reach to 1.1-1.3 times of bodyweight at 25% of gait cycle and the second peak appeared little lower at 70% of gait cycle. The GRF in posterior direction reached its peak at 30%, and then turned to anterior with its peak at 83% gait cycle. The GRF had small variation at the internal to external direction.All of the coefficients of multiple correlations (CMC) of GRF and ankle joint movements were close to or greater than 0.90. Conclusion This custom-made gait simulator has good gait simulation ability with high intra repeatability in respect of ankle rotation and ground reaction force, and can satisfy the request for ankle and foot biomechanics research.

Neurogenic bowel dysfunction (NBD) manifested as constipation and fecal incontinence often occurs after spinal cord injury (SCI).NBD affects patients' quality of life and is an urgent clinical problem to be solved.The mechanism of NBD is related to central and autonomic nervous system dysfunction,intestinal nervous system dysfunction,changes in intestinal microorganism composition and abnormal content of neurotransmitters.The evaluation method of NBD is mainly based on scoring and imaging,which lacks unified criteria,and the treatment method for NBD is the combination of traditional Chinese and Western medicine.The author summarizes the mechanism,evaluation method,treatment and nursing of NBD in order to provide new insight into these aspects to improve clinical efficacy.

Objective To investigate the colonization of Gram-negative bacilli carrying mcr-1 gene in intestinal tracts of inpatients and people having physical examination for further elucidating the molecular and epidemiological features of mcr-1 gene. Methods A total of 1263 and 750 fecal specimens were col-lected from inpatients in the First Affiliated Hospital of Guangzhou Medical University and people having physical examination in the Kingmed Physical Examination Centre, respectively. Drug-resistant bacteria were isolated using Maconkey agar supplemented with colistin. PCR was performed to detect the bacteria carrying mcr-1 gene. Multilocus sequence typing ( MLST) and enterobacterial repetitive intergenic consensus-PCR ( ERIC-PCR) were used for homology analysis. The transferability of mcr-1 gene was verified by plasmid transfer assays. Plasmids of mcr-1-carrying strains were typed by PCR-based replicon typing techniques. Twelve virulence-related genes were also detected by PCR. Results Ninety-two colistin-resistant strains were isolated from the 1263 samples from inpatients(7. 3％, 92/1263) and two of them were positive for mcr-1 gene ( one strain also carried the blaNDM-5 gene) . Thirty-six colistin-resistant strains were isolated from the 750 samples of physical examination group (4. 8％, 36/750) and one of them carried the mcr-1 gene. MLST analysis showed that three mcr-1-carrying Escherichia coli strains ( minimum inhibitory concentration of colistin:8 μg/ml) belonged to three different sequence types. Moreover, they exhibited different banding patterns in ERIC-PCR analysis. All of the mcr-1-carrying isolates could transfer mcr-1 gene to the recipient strains successfully. Six types of incompatibility plasmids were detected in the mcr-1-carrying isolates ( IncFⅡ, IncX2, IncHI2, IncFIB, IncX4 and IncX1). Virulence-related genes fimH, iutA and fyuA were detec-ted in all mcr-1-carrying Escherichia coli strains. Conclusions Colistin-resistant strains and mcr-1 gene are prevalent in inpatients and people having physical examination, which brings potential risk for the control of clinical infections.

Objective: To explore the mid-term efficacy of derotation of talus and medial column fusion for stage II-V Müller-Weiss disease (MWD). Methods: Data of thirty-six patients (38 feet) with MWD treated by derotation of talus and talona-vicular (TN) or talonavicular-cuneiform (TNC) arthrodesis in our center during January 2008 to December 2016 were retrospective-ly analyzed. There were 3 males (3 feet) and 33 females (35 feet) with an average age of 54.0±9.2 years old (range, 32-80 years old); there were 11 right feet and 27 left feet. According to Maceira and Rochera staging system, there were 9 stage II cases, 11 stage III cases, 10 stage IV cases and 8 stage V cases. The external rotation of talus was intensively focused. After the TN articular surface was debrided, an "H" shape plate and a hollow lag screw were used to firmly fix the TN or TNC joint. American Orthopae-dic Foot and Ankle Society Scale (AOFAS), visual analog scale (VAS) and relative radiological parameters were evaluated preoper-atively and during follow-up. Results: The mean follow-up duration was 37.2 months (range, 25-113 months). The latest follow-up showed satisfactory outcomes. Overall, AOFAS score was improved from 41.3±11.3 points (range, 20-56 points) preoperatively to 85.5±7.1 points (range, 68-100 points) postoperatively (Z=5.16, P< 0.001), and the VAS score was reduced from 5.6±1.5 points (range, 3-8 points) preoperatively to 0.8±1.2 points (range, 0-4 points) postoperatively (Z=5.19, P< 0.001). These differences of functional score and pain evaluation were statistically significant. The Tomeno-Méary angle decreased from-6.6°±12.2° to 0.5°±2.9° (Z=3.43, P=0.001); the calcaneal pitch angle increased from 13.5°±3.9° to 22.1°±3.4°(t=10.12, P< 0.001), and the talarnavic-ular coverage angle decreased from 27.1°±5.9° to 7.6°±3.3°(Z=5.16, P< 0.001). The AP talar-first metatarsal angle decreased from-16.0°±10.7° to-7.0°±8.5°(t=5.49, P< 0.001). The differences of radiological parameters were statistically significant. Conclusion The mid-term results showed that the TN or TNC joint fusion could achieve a favorable clinical and radiological outcome for MWD patients. Even for the patients with severe deformities (stage II-V), such treatment strategy could also achieve satisfacto-ry deformity correction and functional improvement. Intraoperative restoration of talus rotation is the key to normal alignment of the subtalar joint/TN joint.

OBJECTIVETo evaluate the differences in the clinical therapeutic effects on spasmodic hemiplegia after stroke among the alliance therapy of scalp acupuncture, music therapy combined with rehabilitation, the simple rehabilitation therapy and the combination of music therapy and rehabilitation.

METHODSA total of 76 patients of post-stroke spasmodic hemiplegia were randomized into a rehabilitation group (25 cases), a combination group with music therapy and rehabilitation (25 cases) and an alliance therapy group with scalp acupuncture, music therapy and rehabilitation (26 cases). In the rehabilitation group, the routine rehabilitation therapy was applied, including the removal of various incentives that cause spasm, the correction of body position and the physical therapy. In the combination group, the music therapy was added on the basis of the treatment as the rehabilitation group. The music physician used the rhythmic auditory stimulation, the patterned sensory enhancement and the therapeutic instrumental music playing to set up the task in the treatment. In the alliance therapy group, scalp acupuncture was added on the basis of the treatment as the combination group. The anterior oblique line of vertex-tempora (MS 6) and the posterior oblique line of vertex-tempora (MS 7) on the contralateral side were selected and stimulated with penetrating needling technique. The needles were retained. During the needling retaining, the needles were rotated once every 10 min, for 2 min each time. The treatment was given one session a day, totally for 5 sessions a week, continuously for 4 weeks. The Fugl-Meyer assessment (FMA), Barthel index (BI) and the modified Ashworth scale (MAS) of the affected elbow and the passive knee movement at static condition were observed in the patients before and after treatment.

RESULTSThe results of FMA, BI and MAS were not different before treatment in the patients among the three groups (all>0.05), indicating the comparability among groups. After treatment, FMA and BI scores were all increased apparently in the three groups as compared with those before treatment (all<0.05). MAS grade was reduced remarkably as compared with that before treatment (all<0.05). After treatment, FMA and BI scores in the alliance therapy group were higher than those in the combination group and the rehabilitation group (all<0.05). FMA and BI scores in the combination group were higher than those in the rehabilitation group (both<0.05). MAS grade in the alliance therapy group was lower than those in the combination group and the rehabilitation group (both<0.05). MAS grade in the combination group was lower than that in the rehabilitation group (<0.05).

CONCLUSIONThe alliance therapy with scalp acupuncture, music therapy and rehabilitation achieve the remarkable clinical therapeutic effects on post-stroke spasmodic hemiplegia as compared with the routine rehabilitation and the combination of music therapy and rehabilitation.
