ABSTRACT
This study aims to explore the effect of "Trichosanthis Fructus-Allii Macrostemonis" combination(GX) on the activation of NOD-, LRR-, and pyrin domain-containing protein 3(NLRP3) inflammasome, the release of inflammatory cytokines, and the level of autophagy in RAW264.7 macrophage damaged by lipopolysaccharide(LPS), and the mechanism of GX against inflammatory response in macrophages. To be specific, LPS was used to induce the injury of RAW264.7 cells. Cell Counting Kit-8(CCK-8) assay was employed to measure the survival rate of cells, and Western blot to detect the protein expression of NLRP3, apoptosis-associated speck-like protein(ASC), cysteine-aspartic acid protease(caspase)-1, interleukin(IL)-18, IL-1β, microtubule-associated protein light chain 3(LC3)-Ⅱ, and selective autophagy junction protein p62/sequestosome 1 in RAW264.7 macrophages. ELISA was used to measure the levels of IL-18 and IL-1β in RAW264.7 cells. Transmission electron microscopy was applied to observe the number of autophagosomes in RAW264.7 cells. Immunofulourescence staining was used to detect the expression of LC3-Ⅱ and p62 in RAW264.7 cells. The result showed that GX significantly reduced the protein expression of NLRP3, ASC, and caspase-1 in RAW264.7 cells, significantly increased the protein expression of LC3Ⅱ, decreased the expression of p62, significantly inhibited the secretion of IL-18 and IL-1β, significantly increased the number of autophagosomes, significantly enhanced the immunofluorescence of LC3Ⅱ, and reduced the immunofluorescence of p62. Furthermore, 3-methyladenine(3-MA) could reverse the inhibitory effect of GX on NLRP3, ASC, and caspase-1 and reduce the release of IL-18 and IL-1β. In summary, GX can increase of the autophagy activity of RAW264.7 and inhibit the activation of NLRP3 inflammasome, thereby reducing the release of inflammatory cytokines and suppressing inflammatory response in macrophages.

Objective: To compare the predictive efficacy of the two thrombosis risk assessment scores (Padua and IMPEDE scores) in venous thromboembolism (VTE) within 6 months in patients with newly diagnosed multiple myeloma (NDMM) in China. Methods: This study reviewed the clinical data of 421 patients with NDMM hospitalized in Beijing Jishuitan Hospital from April 2014 to February 2022. The sensitivity, specificity, accuracy, and Youden index of the two scores were calculated to quantify the thrombus risk assessment of VTE by the Padua and IMPEDE scores. The receiver operating characteristics curves of the two evaluation scores were drawn. Results: The incidence of VTE was 14.73%. The sensitivity, specificity, accuracy, and Youden index of the Padua score were 100%, 0%, 14.7%, and 0% and that of the IMPEDE score was 79%, 44%, 49.2%, and 23%, respectively. The areas under the curve of Padua and IMPEDE risk assessment scores were 0.591 and 0.722, respectively. Conclusion: IMPEDE score is suitable for predicting VTE within 6 months in patients with NDMM.

This study aimed to investigate the mechanism of "Trichosanthis Fructus-Allii Macrostemonis Bulbus" (GX) on phlegm and blood stasis syndrome (PBSS) rats combining the methods of network pharmacology and experimental verification. Animal experiment ethical requirements were approved by the Ethical Committee Experimental Animal Center of Anhui University of Chinese Medicine (grant number: AHUCM-rats-2021070). Based on the HPLC-Q-TOF-MS analysis and database, 69 chemical constituents of GX and 163 targets of GX for the treatment of phlegm and blood stasis-related cardiovascular diseases were obtained. Then, key targets such as serine/threonine kinase 1 (Akt1), tumor necrosis factor (TNF), interleukin 6 (IL6), vascular endothelial growth factor A (VEGFA), cellular tumor antigen p53 (Tp53) were screened. Pathway analysis showed that the targets of GX in the treatment of phlegm and blood stasis-relate cardiovascular diseases were mainly involved in PI3K/Akt signaling pathway, sphingolipid metabolism, platelet activation, hypoxia inducible factor-1 (HIF-1), ras-proximate-1 (rap1) and other signaling pathways. In addition, molecular docking analysis showed that apigenin, cucurbitacin D, linolenic acid and kaempferol and other key components had potential binding ability with Akt1, TNF, IL6, VEGFA and Tp53. In the animal experiments, compared to the phlegm and blood stasis syndrome group, GX could significantly improve the traditional Chinese medicine syndrome score, blood lipid, vascular endothelial structure disorders and reduce serum endothelin-1 (ET-1) level, increase serum nitric oxide (NO) and endothelial nitric oxide synthase (eNOS) levels, which could restore aortic endothelial function. In addition, the expression of intercellular cell adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1) in aorta could be significantly reduced, which could improve the vascular endothelial injury of aorta. Western blot revealed that GX could significantly decrease the phosphorylation levels of phosphoinositide 3-kinase (PI3K) and Akt in aorta. This study revealed the mechanism of GX in treatment of phlegm and blood stasis-relate cardiovascular diseases is consistent with the characteristics of multiple ingredients, multiple targets and multiple pathways. In addition, this study also clarified that the reversal of pathological of phlegm and blood stasis syndrome rats may be related to GX inhibiting PI3K/Akt signaling pathway, which could improve vascular inflammation and vascular endothelial function injury.
ABSTRACT
Objective:To study the efficacy and safety of bone-filling mesh container plasty in the treatment of posterior wall fracture of vertebra caused by spinal metastases.Methods:This study is a retrospective analysis of 65 patients with pathological fractures of the vertebra caused by vertebral metastases treated with bone-filling mesh container plasty from January 2015 to December 2019. There were 21 males and 44 females, 70.3±10.8 (46-90) (years). According to primary tumor, there were 25 cases of lung cancer, 14 cases of breast cancer, 11 cases of digestive system cancer, 13 cases of urinary system cancer, 1 case of lymphoma and 1 case of ovarian cancer. In the segment of vertebral metastases, there were 2 cases of T 2 vertebra, 1 case of T 5 vertebra, 1 case of T 6 vertebra, 2 cases of T 8 vertebra, 1 case of T 9 vertebra, 5 cases of T 10 vertebra, 4 cases of T 11 vertebra, 15 cases of T 12 vertebra, 12 cases of L 1 vertebra, 8 cases of L 2 vertebra, 8 cases of L 3 vertebra, 4 cases of L 4 vertebra, and 2 cases of L 5 vertebra. According to the CT images of the patient's vertebra before operation, the area of the damaged posterior wall of the vertebra is measured as s, and the area of the posterior wall of the intact vertebra is measured as S. The ratio of posterior wall damage is calculated as R= s/ S, and the value of R represents the degree of damage to the posterior wall of the vertebra. According to the size of the R value, the patients were divided into four groups, typeⅠ( R≤25%, 21 cases), typeⅡ(25%< R≤50%, 22 cases), typeⅢ (50%< R≤75%, 14 cases), typeⅣ( R>75%, 8 cases). The visual analog scale (VAS), Oswestry disability index (ODI) and activity of daily living (ADL) before and 1 day after surgery, 1 month after surgery, and 3 months after surgery were analyzed and compared to evaluate the efficacy of bone-filling mesh container plasty. Pairwise comparisons were performed to verify whether there is a difference in efficacy, bone cement leakage and postoperative complications. Results:All 65 patients were followed up for 3-6 months, with an average of 3.8 months. The VAS scores before surgery, postoperative day 1, postoperative 1, 3 months were 7.32±0.99, 4.14±1.06, 4.11±0.97, and 4.34±1.11, respectively, with a statistically significant difference ( F=149.20, P<0.001). ODI of preoperative, postoperative day 1, postoperative 1, and 3 months were 69.45%±4.15%, 36.65%±3.72%, 36.84%± 3.38%, 37.78%±3.45%, respectively, with a statistically significant difference ( F=840.88, P<0.001). ADL score of preoperative, postoperative day 1, postoperative 1, and 3 months were 71.31±12.81, 79.85±9.14, 78.92±8.95, and 78.31±8.67, respectively, with a statistically significant difference ( F=149.20, P<0.001). There was no significant difference in VAS, ODI and ADL scores between types I and IV (all P>0.05), but with the increase of R value, the leakage rate of intraspinal bone cement would increase correspondingly. Eleven cases occurred bone cement leakage with the rate of 17%. The leakage rate of type I and II was 0, type III was 7.1% (1/14), and type IV was 37.5% (3/8). All patients did not have systemic complications such as allergies, shock, decreased oxygen saturation, etc., and there were no bleeding, infection, nerve root symptoms or cement insertion syndrome after surgery. Conclusion:Bone-filling mesh container plasty can significantly improve the pain symptoms of patients with spinal metastases and recovery functions. The degree of damage to the posterior vertebra has no effect on the efficacy of the surgery. As the degree of damage to the posterior wall of the vertebra increases, the risk of complications of bone cement leakage in the spinal canal will increase.
ABSTRACT
Objective:To evaluate the efficacy and safety of allopurinol in the treatment of chronic kidney disease.Methods:The databases of Embase, PubMed and the Cochrane library were searched for randomized controlled trials of allopurinol in patients with chronic kidney disease. According to the Cochrane system evaluation method, two evaluators independently screened the literature and extracted the data, and analyzed the results with Revman 5.3 software.Results:Finally, 10 articles were included, including 940 patients (472 in the experimental group and 468 in the control group). Meta analysis showed that allopurinol treatment could reduce blood uric acid ( MD=-2.40, 95% CI: -2.74--2.05, P<0.01), 24-hour urinary protein ( MD=-0.61, 95% CI: -1.17--0.06, P=0.03) and increase estimation of glomerular filtration rate(eGFR) ( MD=2.51, 95% CI: 1.86-3.17, P<0.01). There was no significant difference in adverse events between the experimental group and the control group ( OR=1.40, 95% CI: 0.61-3.19, P=0.42), but allopurinol treatment could reduce the risk of cardiovascular events ( OR=0.58, 95% CI: 0.38-0.89, P=0.01). Conclusions:Allopurinol treatment of chronic kidney disease can reduce urinary protein, improve eGFR, and reduce the risk of cardiovascular events.

ABSTRACT
Objective:To analyze the clinical efficacy of inter-spinal distraction fusion and fixation and Posterior lumbar interbody fusion in the treatment of lumbar disc herniation with stenosis, and to evaluate the health economics of the two surgical methods.Methods:Retrospectivly analyzed the clinical data of 400 patients with lumbar disc herniation with stenosis, who were enrolled in Beijing Friendship Hospital, Capital Medical University from Jan. 2015 to Jan. 2019, including 190 male cases and 210 female cases, aged from 50 to 87 years old, with the average age of 67.97. All patients were divided into two groups according to different surgical methods. Among them, 200 patients used interspinous process fusion and distraction fixation (ISDFF group), the other 200 cases used posterior lumbar decompression and pedicle internal fixation (PLIF group). All patients completed the follow-up time of more than 1 year after operation. The basic information of patients′ age, gender, total number of days in hospital, intraoperative bleeding, operation time, surgical incision length and other basic information were observed. The Oswestry dysfunction index (ODI), the Japanese Orthopaedic Association Score (JOA) and the visual analog scale (VAS) were used to evaluate the relief of symptoms before and after the two groups of patients. Total medical expenses, anesthesia expenses, surgical expenses and other expenses were analysed. The software of SPSS 20.0 were conducted to analyze data.Results:The patients in the ISDFF group were (70.84±8.93) years old, and the PLIF group was (65.10±10.23) years old ( t=5.98, P=0.008). The operation time in the ISDFF group was (59.21±16.22) min, and the operation time in the PLIF group was (81.31±17.24) min( t=13.20, P<0.001). The bleeding volume of the ISDFF group was (33.24±11.31) mL, and the bleeding volume of the PLIF group was (67.30±17.61) mL ( t=23.02, P<0.001). The length of the surgical incision in the ISDFF group was (8.27±2.53) cm, and the length of the surgical incision in the PLIF group was (11.15±1.91) cm ( t=11.848, P<0.001). The total hospitalization time in the ISDFF group was (15.15±0.54) days, and the total hospitalization time in the PLIF group was (19.86±0.97) days( t=4.26, P<0.001). There was no significant difference in preoperative ODI, JOA and VAS between the two groups ( P>0.05). Symptoms of postoperative patients were significantly improved compared with preoperative. There were statistical differences in ODI, JOA and VAS between the two groups before and after operation ( P<0.05). However, ODI, JOA and VAS were no statistical difference between the two groups after operation. Complications occurred in 5 cases of the two groups of patients, including two cases of superficial infection in the PLIF group, two cases of dural tear in the PLIF group, one case of spinous process fracture in the ISDFF group. The total hospitalization fee for ISDFF was (57 450±8 670) (yuan), and the total hospitalization fee for PLIF was (75 770±1 640) (yuan), with statistical differences ( t=9.92, P<0.001). The cost of ISDFF operation was 1864±38.19 (yuan), and the cost of PLIF operation was 2352±41.39 (yuan) ( t=8.65, P<0.001). ISDFF antibacterial drug usage fee was 635.5±64.69 (yuan), PLIF antibacterial drug usage fee was 1449±307.1 (yuan) ( t=2.59, P<0.001).

The efficacy and adverse events (AEs) of bendamustine combination regimen were retrospectively analyzed in the 16 patients.Results:The median treatment lines for 16 patients with RRMM who received bendamustine combination regimen was 4 lines, and the median course of treatment was 3 (1-8). The median follow-up time after bendamustine treatment started was 5.3(1.3-9.2)months. Among the 16 cases, the disease control rate (DCR), overall response rate(ORR), and ≥ very good partial remission (VGPR) rate were 13/16, 5/16, 4/16 respectively. The median PFS was 4.9 months. Among them, the ORR of bendamustine combined with immunomodulators was higher. AEs were anemia, leukopenia, neutropenia, thrombocytopenia and fatigue. No patients who stopped treatment and adjusted the dose due to AEs.Conclusions:Bendamustine combination regimen is an effective and safe regimen for relapsed/refractory multiple myeloma.
ABSTRACT
OBJECTIVE@#To investigate the expression of CD319 and CD269 in plasma cells of patients with multiple myeloma (MM) and the feasibility of using CD319 instead of CD38 as a gating antigen in immunophenotyping and minimal residual disease (MRD) monitoring.@*METHODS@#The expression levels of CD319 and CD269 antigens in clonal bone marrow plasma cells of 387 patients were detected by CD38/CD138 gating strategy with 8-color flow cytometry, and the stability of antigens was also analyzed, and the sensitivity and correlation of two different gating strategies employing CD319/CD138 and CD38/CD138 were compared as well. The control group consisted of 53 cases with non-malignant blood disease matched by age and sex.@*RESULTS@#Monoclonal plasma cells were detected in 303 of 387 MM patients, among which 277 cases (91.42%) were positive for CD269, and all cases were positive for CD319 (100%). In newly diagnosed MM (NDMM) and recurrent refractory MM (RRMM) patients, the expression levels of CD269 were 97.53% (0-99.92%) and 94.96% (0.22%-99.99%), respectively, while levels of CD319 were 99.90% (87.77%-100%) and 99.78% (63.12%-100%), respectively. The expression levels of CD269 and CD319 in the control group were 97.00% (77.00%-100%) and 100% (89.00%-100%), respectively. There were no significant differences in the expression levels of CD269 and CD319 among NDMM, RRMM and the control group. Patients acquiring therapeutic effects were divided into complete remission (CR) group, very good partial response (VGPR) group and partial response (PR) group. Gating with CD38/CD138, median MRD values were 0.76% (0-1.88%), 0.77% (0-4.96%) and 1.75% (0.09%-10.90%) in the three groups, respectively, while gating with CD319/CD138, median MRD values were 0.57% (0.18%-1.96%), 1.07% (0.12%-4.85%) and 1.77% (0.08%-8.22%), respectively. There was no significant difference in MRD level by the two gating strategies, but a good correlation between the two (r=0.808, P<0.05). In addition, in 4 patients treated by CD38 monoclonal antibody (DARA), the expression level of CD38 was observed to be down-regulated or even negative after treatment. When the MRD level was very low, CD38/CD138 gating resulted in false MRD@*CONCLUSION@#CD319 and CD269 express stably and continuously in plasma cells of MM patients at different disease stages. CD319 can be used as an alternative of CD38 for immunophenotyping and MRD detection, especially for MRD detection after DARA treatment, while CD269 is suitable for detection before BCMA-CAR-T treatment.

OBJECTIVE：To compare th e clinical efficacy and safety of trazodone combined with venlafaxine and venlafaxine in the treatment of major depressive disorder （MDD）. METHODS ：Totally 160 patients with MDD who were treated in our hospital from Sept. 2018 to Oct. 2020 were all enrolled and divided into control group （80 cases）and observation group （80 cases）according to random number table. Control group was treated with V enlafaxine hydrochloride sustained-release tablets 75 mg orally，once every morning. Observation group was additionally treated with Trazodone hydrochloride tablets 25 mg orally ，twice a day，on the basis of control group. The dosage was adjusted according to the efficacy and tolerance. Hamilton depression scale 24 （HAMD-24），Montgomery-Asperger depression scale （MADRS） and Pittsburgh sleep quality index （PSQI） were compared between 2 groups before and after treatment. Clinical efficacies were compared and the occurrence of ADR were recorded. RESULTS：A total of 12 patients were expelled ，and 148 patients were eventually included ，involving 73 cases in control group and 75 cases in observation group. Before treatment ，there was no significant differences in HAMD- 24，MADRS or PSQI scores between 2 group（P＞0.05）. After 1，3，5 and 8 weeks of treatment ，HAMD-24 and MADRS scores of 2 groups were significantly lower than before treatment ，and the observation group was significantly lower than the control group （P＜0.05）. PSQI scores of observation group were significantly lower than before treatment and control group during the same period （P＜0.05），while there was no significant difference in PSQI scores of control group before and after treatment （P＞0.05）. The total response rate of observation group （96.00％）was significantly higher than control group （86.30％）（P＜0.05）. There was no statistical significance in the incidence of ADR between 2 groups（P＞0.05）. CONCLUSIONS ：Trazodone combined with venlafaxine and venlafaxine alone both have good efficacy and similar safety in the treatment of MDD ， but clinical efficacy of trazodone combined with venlafaxine is better.

Objective:To investigate the effects and potential mechanisms of resveratrol on obesity in elderly mice.Methods:In this study, 3 groups were randomly formed for 32-week-old mice and for 48-week-old mice.The normal diet group received regular chow and 0.3 ml saline by gavage once a day, the high-fat diet group received a high-fat diet(containing 21% fat and 1.25% cholesterol)and 0.3 ml saline once a day, and the high-fat diet plus resveratrol group received a high-fat diet and resveratrol(22.4 mg/kg, dispersed in 0.3 ml saline)by gavage once a day.After 12 weeks, body weight and adipose tissues were measured.Plasma leptin concentrations were determined by an enzyme-linked immunosorbent assay(ELISA), and values for hypertrophic obesity-related indexes of mice were obtained by quantitative real-time PCR.Results:The body weight and the proportion of subcutaneous fat tissues were lower in the high-fat diet plus resveratrol group than in the high-fat diet group[(34.43±3.23)g vs.(53.16±2.16)g, (3.21±1.58)% vs.(4.86±0.64)%, P<0.01], and were similar to those in the normal diet group.Resveratrol had a more obvious inhibitory effect on leptin in elderly mice than in middle-aged mice.In elderly mice, the plasma leptin concentration was lower in the high-fat diet plus resveratrol group than in the high-fat diet group[(0.015±0.009)g/L vs.(0.100±0.027)g/L]and the normal diet group( F=19.85, P=0.001), and it was similar to that in the middle-aged mice on a normal diet.Resveratrol significantly increased the expression of peroxisome proliferator-activated receptor gamma(PPARγ)and glucose transporter 4(GLUT4)and reduced the expression of tumor necrosis factor-α(TNF-α)( F=10.79, 9.31 and 7.02, P=0.003, 0.006 and 0.010). Conclusions:Resveratrol can significantly improve hypertrophic obesity in elderly mice, and the inhibition of leptin secretion and up-regulation of PPARγ may be the key mechanisms.
ABSTRACT
Crassostrea sikamea (C.sikamea) is an important edible and medicinal seafood in China. In the present study, a compound named flazin was separated and identified from the ethyl acetate extract of C.sikamea (EAECs) for the first time. In addition, the 3-(4, 5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetra zolium (MTS) assay revealed that EAECs and flazin inhibited the transformation of splenic lymphocytes in vitro. Moreover, flazin (20 μg·mL

Objective:To investigate the balance in young adult with scoliosis. Methods:From June to December, 2020, 30 college students with scoliosis in the outpatient department of Rehabilitation Department of Kunming Medical University Hospital were as the patients, and 30 normal peers were as the controls. They were measured with Pro-Kin balance test system to assess the static stability of both feet standing with eyes opened and closed, and the static and dynamic limit of stability (LOS) of both feet standing. Results:The moving distance of center of pressure (COP) on the Y-axis was longer in the patients than in the controls with both eye-opened and eye-closed (t > 2.022, P < 0.05). The static and dynamic LOS was less in the patients than in the controls (t > 3.365, P < 0.01). For static LOS, it was less in all the directions except left-forward and backward (t > 2.410, P < 0.05); for dynamic LOS, it was less in the directions of forward, right, left and left-forward (t > 2.446, P < 0.05). Conclusion:Both static and dynamic balance is deficient for yong adults with scoliosis, which may result in risk of fall.
ABSTRACT
OBJECTIVE@#To evaluate the effectiveness of super-selective renal artery embolization in treatment of post-percutaneous nephrolithotomy bleeding, and to analyse the causes of failure embolization.@*METHODS@#In the study, 65 post-percutaneous nephrolithotomy patients with severe renal bleeding and hemodynamic instability were treated by super-selective renal artery embolization. First of all, we performed selective renal arteriography. After clarifying the location of the bleeding, superselective intubation of the injured vessel with a microcatheter was carried out. Then the injured vessel was embolized with Tornado micro-coil. When complete embolization was not achieved with micro-coil, a small amount of gelatin sponge particles were added. If there was no positive finding of the beginning selective renal arteriography, the following measures could be taken to prevent missing lesions: (1) Abdominal aorta angiography was performed to determine whether there were anatomical variations, such as accessory renal arteries or multiple renal arteries; (2) Ultra-selective intubation angiography next to the nephrostomy tube path was performed; (3) Renal arteriography was repeated; (4) Renal arteriography after removing the nephrostomy tube while retaining the puncture channel. We evaluated the different angiographic findings and analysed the causes of embolization failure.@*RESULTS@#Bleeding was successfully controled in 60 patients (62 kidneys) whose renal arteriography was postive. Positive findings included: pseudoaneurysm formation, patchy contrast extravasation, pseudoaneurysm combined with arteriovenous fistula, contrast agent entering the collection system, extravascular perinephric leakage of contrast. After first embolization, bleeding was controled in 53 patients (55 kidneys). The success rate after the first and second embolization was 88.7% and 96.7% respectively. The second session was required because of failure to demonstrate bleeding arteries during the first session (4 patients, 57.1%) and recurrent hemorrhage of the embolized injured arteries (2 patients, 28.6%). In 5 patients with no positive findings, after conservative treatment, hematuria disappeared. All the patients were followed up for 3, 6, and 12 months after embolization, and no hematuria occurred again, and no sustained and serious renal insufficiency.@*CONCLUSION@#Super-selective renal artery embolization is an effective treatment for post percutaneous nephrolithotomy bleeding. The main cause of failure is omitting of injured arteries during renal arteriography. Renal artery branch injury has various manifestations. Attention should paid to the anatomical variation of the renal artery, and patient and meticulous superselective intubation angiography is the key to avoiding missing the lesion and improving the success rate of embolization.

Objective:To evaluate the clinical effect of interspinous process fusion (BacFuse) in the treatment of lumbar disc herniation (LDH) with rheumatoid arthritis (RA).Methods:A retrospective analysis of the clinical data of 50 patients with RA and LDH from May 2013 to June 2018 in department of orthopedics, Beijing Friendship Hospital, Capital Medical University was conducted. Among them, there were 9 males and 41 females, aged (66.60±4.23) years, with an age ranging from 54 to 84 years. According to different surgical methods, the patients were divided into posterior lumbar interbody fusion (PLIF) group ( n=26) and BacFuse group ( n=24). Operative time, intraoperative blood loss and operative complications of the two groups were observed. Oswestry disability index (ODI) and Japanese Orthopaedic Association (JOA) scores were used to evaluate the clinical effect at preoperative, 3 days of postoperative and the last follow-up. The measurement data were expressed as mean±standard deviation( Mean± SD), comparison between groups used t test and the count data were expressed as percentage(%), the chi-square test was used for comparison between the two groups. The clinical effect of the two groups were compared by repeated analysis of variance. Results:In the PLIF group, the operation time and bleeding volume were (174.62±55.59) min, (309.62±30.26) mL, respectively. In the BacFuse group, the operation time and bleeding volume were (71.25±12.96) min, (57.92±9.32) mL, respectively. The differences between the two groups were statistically significant ( P<0.05). The operative complications in the PLIF group (8 cases) was significantly higher than that in the BacFuse group (2 cases) , the difference between the two groups was statistically significant ( χ2 = 3.926, P=0.048). There were significant differences between every two scores among the preoperative, 3 days of postoperative and last follow-up in ODI of the PLIF group( F=760.231, P<0.001). The preoperative, 3 days of postoperative and last follow-up ODI scores of the BacFuse group were significant differences between every two scores ( F= 952.525, P<0.001). There were no significant differences in ODI scores between the two groups [( t=-1.13, P=0.263), ( t=0.706, P=0.483), ( t=0.389, P=0.699)]. There were significant differences between every two scores among the preoperative, 3 days of postoperative and last follow-up in JOA of the PLIF group( F=406.012, P<0.001). The preoperative, 3 days of postoperative and last follow-up in JOA scores of the BacFuse group were significant difference between every two scores ( F=457.760, P<0.001). There were no significant differences in JOA scores between the two groups [( t=0.825, P=0.414), ( t=1.909, P=0.062), ( t=1.086, P=0.283). Conclusions:Compared with PLIF, BacFuse has a similar clinical effect in the treatment of LDH with RA, but BacFuse is less invasive and has fewer postoperative complications. BacFuse is an effective minimally surgical method for the treatment of LDH with RA.
ABSTRACT
Objective:To compare the clinical outcomes of percutaneous vertebroplasty (PVP) and the Vesselplasty for kümmell′s disease.Methods:A retrospective case-control study was used.The clinical data of 62 patients with kümmell′s disease were selected in Beijing Friendship Hospital, Capital Medical University, from January 2017 to January 2019. There were 19 males and 43 females, aged (70.94±7.69) years, with range from 60 to 85 years. The patients were divided into two groups according to different operation methods. The 36 patients treated by PVP and 26 patients treated by Vesselplasty were followed up at least one year after operation. The follow-up time was (17.55±4.22) months. The operation time, incidence of cement leakage, preoperative and postoperative Cobb′s angle, visual analogue score (VAS) 1 week and 1 year after operation were observed. The measurement data were expressed as mean±standard deviation ( Mean± SD), independent sample t-test was used for comparison between groups. The count data were expressed as percentage (%), chi-square test was used for comparison between groups. Results:All the operation was successfully completed. No serious complications such as paraplegia, bone cement allergy, pulmonary embolism were occurred. The operation time was no significant difference between the two groups ( P< 0.05). The incidence of cement leakag was 41.67% (15/36) in PVP group and 11.54% (3/26) in Vesselplasty group. The latter was significantly lower than the former, with statistically significant differences between the two groups ( P< 0.05). In PVP group, the Cobb′s angles of preoperation, postoperation 1 year and difference were (26.23 ± 5.62)°, (17.46 ± 3.01)° and (8.78 ± 4.62)°, respectively, in Vesselplasty group, they were (28.74 ± 6.68)°, (16.68 ± 2.79)° and (12.07 ± 5.72)°, respectively. Cobb′s angle of the two groups was significantly improved after operation. In the comparison between the groups, the improvement of the Cobb′s angle in the Vesseplasty group was better than that of the PVP group, and the difference was statistically significant ( P< 0.05). The VAS score in PVP group was (8.42±1.03) scores in preoperation, (3.06±1.01) scores in 1 week, (0.81±0.75) scores in 1 year. The VAS score in Vesselplasty group was (8.35±1.02) scores in preoperation, (2.88±1.11) scores in 1 week and (1.04±0.87) scores in 1 year. Compared with pre-operation, the VAS scores of the two groups decreased significantly at 1 week and 1 year after operation, and the difference was statistically significant ( P<0.05). There was no significant difference in VAS between groups 1 week after operation and 1 year after operation ( P>0.05). Conclusion:Vesselplasty can effectively control the flow and distribution of bone cement in the vertebral body, effectively reduce the leakage of bone cement, and better correct kyphosis.
ABSTRACT
Objective:To observe the full-field ERG (ff-ERG) characteristics of patients with acute regional occult outer retinopathy (AZOOR).Methods:A retrospective observational study. From June 2017 to June 2019, 62 eyes of 42 patients (AZOOR group) who were diagnosed with AZOOR in the Department of Ophthalmology of West China Hospital of Sichuan University were included in the study. All patients had no obvious localized disease on the fundus. Among 62 eyes, BCVA of 16 eyes were <0.1, BCVA of 27 eyes were ≤0.5, and BCVA of 19 eyes were> 0.5. From June 2018 to January 2019, 40 normal volunteers (80 eyes) who attended the outpatient clinic of West China Hospital of Sichuan University and passed detailed ophthalmological examination to exclude all eye diseases including refractive errors were selected as the normal control group. All the examined eyes were tested with ff-ERG using the German Roland visual electrophysiological inspection system. The peak times and amplitudes of the waveforms induced by each response of dark adaptation 0.01 ERG, dark adaptation 3.0 ERG, dark adaptation 3.0 ERG, light adaptation 3.0 ERG, and light adaptation 30 Hz flicker ERG were recorded, respectively. The peak time and amplitude of each ff-ERG response between the two groups were compared by independent sample t test. The peak time and amplitude of each ff-ERG response between different BCVA eyes in the AZOOR group were compared by variance test. Results:Compared with the normal control group, 0.01 ERG b wave of the dark adaptation of AZOOR group ( t=3.601, -6.120), 3.0 ERG a wave and b wave of dark adaptation ( t=2.627, -4.263, 3.719,-5.866), 3.0 Oscillation potential P2 wave of dark adaptation ( t=-6.625), 3.0 ERG a wave and b wave of bright adaptation ( t=3.762, -3.612, 3.648, -3.739) and 30 Hz flicker ERG P wave of bright adaptation ( t=-3.832), all peak time of those were significantly delayed, the amplitude decreased, and the difference was statistically significant ( P<0.05). Comparison of different BCVA eyes in the AZOOR group showed that 0.01 ERG b wave amplitude of dark adaptation ( F=3.950), 3.0 ERG a peak and b wave amplitude of dark adaptation ( F=4.408, 4.876), oscillation potential P2 wave amplitude of dark adaptation ( F=4.295), 3.0 ERG b wave amplitude of bright adaptation ( F=4.344) and 30 Hz flicker ERG P wave amplitude of bright adaptation ( F=4.483) of differences were statistically significant ( P<0.05). There was no statistically significant difference in waveform peak time and amplitude of the other reactions ( P>0.05). Pairwise comparison results showed that, compared with those with 0.1≤BCVA≤0.5 and BCVA> 0.5, those with BCVA <0.1 dark adaptation to 0.01 ERG b wave, dark adaptation 3.0 ERG b wave, dark adaptation oscillation potential P2 wave, and light adaptation 3.0 ERG b wave and light adaptation 30 Hz scintillation ERG P wave amplitude were significantly reduced, and dark adaptation to 3.0 ERG a peak was significantly delayed, the difference was statistically significant ( P<0.05). Conclusions:The ff-ERG of patients with AZOOR show delayed peak time and decreased amplitude of each response. The worse BCVA are accompanied by the more obvious decrease of each response amplitude of ff-ERG.
