ABSTRACT

Objective: To investigate the clinicopathologic features of primary adrenal NK/T cell lymphoma (PANKL). Methods: Six cases of PANKL were collected at Henan Provincial People's Hospital from January 2000 to December 2021. The clinicopathologic features including morphology, immunophenotype, treatment and prognosis were retrospectively analyzed, and relevant literature was reviewed. Results: There were two males and four females. The median age was 63 years (ranged from 57 to 68 years). The tumors involved bilateral adrenal glands in 4 cases and unilateral adrenal gland in 2 cases. The main clinical symptom was low back pain without obvious cause. Serum lactate dehydrogenase (LDH) is elevated in five cases. The imaging feature was rapidly enlarging mass initially confined to unilateral/bilateral adrenal glands. Morphologically, the lymphoid cells were mainly medium-sized with a diffuse growth pattern. Coagulative necrosis and nuclear fragmentation were common. Angioinvasion was seen. Immunophenotypically, the neoplastic cells were positive for CD3, CD56 and TIA-1 while CD5 was negative in 5 cases. All cases were positive for EBER by in situ hybridization with more than 80% proliferative activity by Ki-67. Four cases received chemotherapy, one case underwent surgery, and one case underwent surgery with chemotherapy. Follow-up was done in 5 cases; one case was lost to follow-up. Three patients died with a median survival of 11.6 months (3-42 months). Conclusions: PANKL is rare with highly aggressive clinical presentation and poor prognosis. Accurate diagnosis entails correlation of histomorphology, immunohistochemistry, EBER in situ hybridization and clinical history.

ABSTRACT

Objective: To understand the incidence trend of liver cancer in China from 2005 to 2016, and explore the correlation between the incidence trend of liver cancer and the incidence trend of hepatitis B. Methods: The incidence data of liver cancer in China from 2005 to 2016 were collected from the Annual Report of Cancer Registry in China. The incidence data of hepatitis B were collected from China Public Health Science Data Center. World standardized incidence rate (WSR) was calculated according to the World Segi's population. Joinpoint regression model was used to analyze the trend of WSR of liver cancer [measured by average annual percentage change (AAPC)]. The age-period-cohort model was fitted to analyze the age, period and cohort effects in people aged 20- years and above. Pearson correlation coefficient was used to explore the correlation between the incidence of liver cancer and the incidence of hepatitis B. Results: The crude incidence of liver cancer in China showed a trend of first increase before 2009 and then relatively stable. The world standardized morbidity rate of liver cancer in China decreased from 19.11 per 100 000 in 2005 to 17.74 per 100 000 in 2016 (AAPC=-0.5%, 95%CI: -1.3%-0.3%, P=0.240). The incidence of liver cancer in male decreased significantly (AAPC=-1.0%, 95%CI: -1.5%--0.5%, P=0.001). The incidence of liver cancer in women increased from 2005 to 2010 [annual percentage change (APC)=1.7%, 95%CI: -0.1%-3.4%, P=0.059] but showed a significant decrease trend from 2010 to 2016 (APC=-1.6%, 95%CI: -2.3%--1.0%, P=0.001). From 2005 to 2016, the incidence of liver cancer showed a decreasing trend in urban areas (AAPC=-0.3%, 95%CI: -0.8%-0.3%, P=0.316) and rural areas (AAPC=-3.9%, 95%CI: -4.4%--3.3%, P<0.001). Risk for liver cancer increased with age, while the period effect showed a trend of first increase then decrease and cohort effect showed a decrease trend. The morbidity rates of both hepatitis B and liver cancer showed decrease trends from 2009 to 2016, and there was a significant correlation (r=0.71, 95%CI: 0.01-0.94, P=0.048). Conclusions: From 2005 to 2016, the morbidity rate of liver cancer in China showed a decrease trend, and there were significant gender and urban-rural area specific differences. Age effect had a great impact on the risk for liver cancer. With the progress of population aging in China, liver cancer is still a public health problem, to which close attention needs to be paid.

ABSTRACT

OBJECTIVE@#To investigate the evolution of blood separation results by gel extraction of multiple myeloma (MM) patients, and to evaluate the clinical value of abnormal blood separation results for the evaluation of disease and prognosis.@*METHODS@#The clinical data of 5 patients diagnosed newly MM patients with abnormal blood separation of gel collection vessels in our hospital were retrospectively analyzed, and the changes of blood separation results and blood index levels were followed up with the improvement of treatment effect, and the correlation of different blood index levels was analyzed.@*RESULTS@#In 5 patients with newly diagnosed MM, the blood separation result showed floating phenomenon after centrifugation, which divided into three layers and the order from top to bottom is separator gel, serum, and red blood cells(RBC). With partial remission of clinical symptoms, the blood separation results were still abnormal, which were divided into three layers from top to bottom: serum, RBC and separator gel. Finally, with complete remission of the disease, blood separation results returned to normal, from top to bottom: serum, separator gel, RBC. With the blood separation results from abnormal to normal, the blood routine indicators: Hb, Hct levels gradually increased, neutrophil/lymphocyte ratio (NLR), monocyte/lymphocyte ratio (MLR) gradually decreased; biochemical indexes: TP, GLB, Ig and β2-MG levels gradually decreased. Tumor load related indicators: serum IL-6, TNF-α, IL-17 levels gradually decreased, and IL-35 levels gradually increased; and the differences were statistically significant (P<0.05). Pearson correlation analysis showed that serum β2-MG was positively correlated with IL-6, TNF-α and IL-17 levels (r=0.710, 0.756, 0.581, P<0.05), and negatively correlated with IL-35 level (r=-0565, P<0.05).@*CONCLUSION@#Abnormal blood separation exists in MM patients, and there are significant differences in blood, tumor load and immune balance related indexes in patients with different blood separation results, which provides partial experimental basis for evaluation of disease, efficacy and prognosis with different blood separation results.

ABSTRACT

OBJECTIVE: To explore the mechanism of bone marrow mesenchymal stem cells(BMSCs) in alleviating silica-induced lung injury in mice. METHODS: Ten specific pathogen free healthy male C57 BL/6 mice were selected for isolating BMSCs and bone marrow macrophages(BMDMs). Transwell chamber was used, BMDMs were inoculated onto the upper chamber and BMSCs in the lower chamber. We divided them into sequencing control group and silica(SiO_2) exposure group. All cells were pre-stimulated with 50 μg/L mass concentration lipopolysaccharide for 4 hours. In the SiO_(2 ) group, 250 mg/L mass concentration SiO_2 was added to the upper chamber of transwell and cultured for 16 hours. Total RNA was extracted from the BMSCs collected from the lower chamber. HiSeq/MiSeq high-throughput sequencing technology was used to detect the BMSCs RNA paired-end sequencing. Transcriptome sequencing data was obtained and bioinformatics analysis was performed. Another 12 specific pathogen free healthy male C57 BL/6 mice were randomly divided into control group and experimental group. All mice received one intra-tracheal injection of 20.0 μL(250 g/L mass concentration) of silica dust suspension. After 6 hours, the mice in the control group was given 500.0 μL of 0.9% sodium chloride solution and mice in the experimental group was given 500.0 μL of BMSCs suspension(cell density 1×10~9/L) by tail vein infusion.Mice were sacrificed 12 hours later. The relative mRNA expression of interleukin(IL)-1 Ra, IL-10, tumor necrosis factor stimulating gene 6(TSG-6) and prostaglandin E2(PGE2) in lung tissues of mice were measured by quantitative real-time PCR(q-PCR). Meanwhile, BMDMs and BMSCs transwell co-culture models were established. The cells were divided into 5 groups: BMSCs group, BMSCs+BMDMs group, BMSCs+BMDMs+ lipopolysaccharide(LPS) group, 50 mg/L SiO_2 group, and 100 mg/L SiO_2 group. After 16 hours of corresponding SiO_2 stimulation, BMSCs of each group were collected and the relative mRNA expression levels of IL-1 Ra, IL-10, TSG-6, and PGE2 in the cells were detected by q-PCR. RESULTS: Compared with sequencing control group, BMSCs co-cultured with SiO_2 had 19 genes up-regulated and 21 genes down-regulated, including 10 genes up-regulated for more than 2.0-fold. The relative mRNA expression of IL-1 Ra, IL-10, PGE2 and TSG-6 in the lung tissue of mice increased in the experimental group than that of the control group(all P<0.05). The relative mRNA expression of TSG-6 increased by 37.5 times higher than that of the control group. Compared with the BMSCs+BMDM+LPS group, the level of TSG-6 mRNA relative expression increased in both the 50 mg/L SiO_2 group and the 100 mg/L SiO_2 group(all P<0.05). CONCLUSION: TSG-6 could be the key factor of BMSCs that can attenuate silica-induced lung injury.

ABSTRACT

The survey was conducted in Shaoxing city from January 2019 to January 2021 among 150 residents aged ≥ 60 years with mild cognitive impairment from Shaoxing People's Hospital and its subordinate branches. The swallowing function was evaluated by eating evaluation questionnaire-10 (EAT-10), and dysphagia (EAT-10 score ≥ 3) was identified in 92 subjects with a prevalence rate of 61.3% (dysphagia group) and other 58 residents without dysphagia was set as normal group. There were significant differences in age, educational level, diet type, history of stroke, history of choking, Mini-mental State Examination (MMSE) score, masticatory function score, the number of drug types, self-care ability (Barthel score) in Activities of Daily Living (ADL) scale between dysphagia group and normal group (all P<0.05). Multivariate logistic analysis showed that age (≥ 80 years old), educational level (junior middle school and below), history of stroke, history of choking cough, MMSE score (<23 points), Barthel score (≤ 60 points), masticatory function score (>3 points) and the number of drug types (≥ 3 kinds) were independent risk factors of swallowing disorder in elderly with mild cognitive impairment; and the type of diet (common diet) was the protective factor. It is suggested that the prevalence of dysphagia in community-dwelling elderly with mild cognitive impairment is high, and necessary measures should be taken to intervene according to its risk factors.

ABSTRACT

Deamidation is one of the most common degradation impurities in protein and peptide drugs. The deamidation of glutamine and asparagine in the protein sequence can lead to changes in the chemical and biological properties of the protein. However, the rutine trypsin-based pretreatment process can significantly increase the artificial deamidation impurities during the digestion process, resulting in high determination level. In this study, after optimizing the conditions of Glu-C enzymatic hydrolysis, we obtained the best enzymatic conditions under acidic condition and the artificial deamidation impurities significantly reduced in digestion process, identified the deamidation site (N48). Through the methodological investigation and comparison of the measurement results of different methods, the specificity, reproducibility and accuracy of the method are verified. The method established in this research has laid a solid foundation for the accurate determination of deamidation impurities in cobratide and its similar protein peptide biochemical drugs.

ABSTRACT

The paper aims to establish the method to determine the monosaccharide composition and monosaccharide ratio in propylene glycol alginate sodium sulphate (PSS). Samples were hydrolyzed with trifluoroacetic acid, neutralized with sodium hydroxide solution after the reaction conditions for sample pretreatment were optimized via orthogonal analysis. A high performance anion exchange chromatograghy (HPAEC) coupled with pulsed amperometric detector (PAD) was performed on a CarboPac®PA20, using 200 mmol·L-1 sodium hydroxide solution and 1 mol·L-1 sodium acetate solution as mobile phase. The established HPAEC-PAD method was validated by testing the linear relationship, precision and accuracy, and showed exclusive, sensitive, rapid and wide use. The monosaccharide composition of PSS from different manufacture can be accurately determined with great significance for the structural identification of PSS.

ABSTRACT

Mesenchymal stem cells(MSCs) have functions such as immune regulation and tissue damage repair, but the specific mechanisms of their effects need to be further studied. Paracrine effect is an important mechanism for MSCs to achieve immune regulation, relieve inflammation and repair tissue damage. Tumor necrosis factor α(TNF-α) stimulated protein 6(TSG-6) is one of the paracrine factors of MSCs, which has significant inflammation inhibitory capability and tissue repair ability. It is an important cytokine of MSCs to exert their anti-inflammatory and anti-fibrotic effects. The MSCs can repair tissue damage in kidney, peritonea, skin, liver, lung, cornea, nervous system, and colon by secreting TSG-6. This powerful repair ability could be attributed to the ability of TSG-6 to inhibit the secretion of pro-inflammatory cytokines and pro-fibrogenic factors, such as TNF-α, interleukin(IL)-6, IL-1β and transforming growth factor-β1, thereby reducing the inflammatory response and fibrosis of the body.

ABSTRACT

Chromosomal abnormalities and Y chromosome microdeletions are considered to be the two more common genetic causes of spermatogenic failure. However, the relationship between chromosomal aberrations and Y chromosome microdeletions is still unclear. This study was to investigate the incidence and characteristics of chromosomal aberrations and Y chromosome microdeletions in infertile men, and to explore whether there was a correlation between the two genetic defects of spermatogenic failure. A 7-year retrospective study was conducted on 5465 infertile men with nonobstructive azoospermia or oligozoospermia. Karyotype analysis of peripheral blood lymphocytes was performed by standard G-banding techniques. Y chromosome microdeletions were screened by multiplex PCR amplification with six specific sequence-tagged site (STS) markers. Among the 5465 infertile men analyzed, 371 (6.8%) had Y chromosome microdeletions and the prevalence of microdeletions in azoospermia was 10.5% (259/2474) and in severe oligozoospermia was 6.3% (107/1705). A total of 4003 (73.2%) infertile men underwent karyotyping; 370 (9.2%) had chromosomal abnormalities and 222 (5.5%) had chromosomal polymorphisms. Karyotype analysis was performed on 272 (73.3%) patients with Y chromosome microdeletions and 77 (28.3%) had chromosomal aberrations, all of which involved sex chromosomes but not autosomes. There was a significant difference in the frequency of chromosomal abnormalities between men with and without Y chromosome microdeletions (P< 0.05).

ABSTRACT

To explore the utility of apparent diffusion coefficient(ADC)histogram analysis for differentiating genetic subtypes of diffuse lower-grade gliomas. A total of 55 patients with WHO grade Ⅱ/Ⅲ diffuse lower-grade gliomas who underwent preoperative routine brain magnetic resonance imaging and diffusion weighted imaging in our center were retrospectively evaluated.Among whom there were 14 patients with isocitrate dehydrogenase(IDH)wild-type gliomas(IDH group),19 patients with IDH-mutant 1p19q intact gliomas(IDH 1p19q group),and 22 patients with IDH-mutant 1p19q co-deleted gliomas(IDH 1p19q group).The whole-lesion ADC values derived from histogram analysis(including ADC,ADC,ADC5%,ADC10%,ADC25%,ADC50%,ADC75%,ADC90%,ADC95%,ADC,mode,range,skewness,kurtosis,standard deviation,inhomogeneity,and entrophy)were measured for each patient.All parameters between the different genetic subtypes were compared by using the Student's test or Mann-Whitney test.Receiver operating curve(ROC)analysis was used to assess the diagnostic performance of ADC histogram in distinguishing the different genetic subtypes. Compared with IDH group,the ADC75%(=0.021),ADC90%(=0.015),ADC95%(=0.014),ADC (=0.035),range(=0.009),standard deviation(=0.001)and inhomogeneity(=0.001)were significantly lower in IDH group;in contrast,the ADC (=0.031)and kurtosis(=0.020)of IDH group were significantly higher than those in IDH group.The ADC(=0.010),ADC5%(=0.016),ADC10%(=0.012),ADC25%(=0.007),ADC50%(=0.005),ADC75%(=0.015),and mode(=0.002)were significantly higher in IDH 1p19q group than in IDH 1p19q group.Inhomogeneity achieved the highest area under ROC(AUC)(0.811)in differentiating IDH gliomas and IDH gliomas,with a cutoff value of 0.229;the sensitivity and specificity were 85.7% and 73.2%.The mode achieved the highest AUC(0.744)in differentiating IDH 1p19q gliomas and IDH 1p19q gliomas,with a cutoff value was 1448.75×10 mm /s;the sensitivity and specificity were 57.9% and 90.9%. ADC histograms analysis may be helpful to differentiate genetic subtypes in lower-grade gliomas.

ABSTRACT

Objective:To investigate the association between the parameters of thin-section computed tomography and the invasion and histological subtypes of subsolid nodules measuring 1-2 centimeters in diameter as lung adenocarcinoma.Methods:We retrospectively reviewed the cases with subsolid nodules measuring 1-2 centimeters on thin-section computed tomography and histologically confirmed as lung adenocarcinoma.Results:A total of 135 patients were enrolled in this study, including 23 with pure ground glass nodules and 112 with part-solid ground glass nodule. We observed significant differences of nodule size, solid component size, consolidation-to-tumor ratio, nodule attenuation and attenuation ratio( P<0.0001). The receiver operating curve indicated certain predictive value of solid component size, nodule attenuation and attenuation ratio: AUC were 0.838(0.756-0.919)、0.823(0.729-0.917) and 0.820(0.726-0.914), respectively. Of the invasive adenocarcinoma, those with solid or micropapillary components merely showed a significance in solid component size( P=0.024). Conclusion:The parameters of thin-section computed tomography of 1-2 centimeters subsolid nodules showed significant differences in varied invasiveness of lung adenocarcinoma, and these could have certain predictive value.

ABSTRACT

Objective:To evaluate the effect of using a walking support band on the gait of stroke survivors.Methods:Sixty stroke survivors were randomly divided into a walking support band group ( n=20), an ankle foot orthosis (AFO) group ( n=20) and a conventional rehabilitation group ( n=20). All three groups received conventional rehabilitation therapy, while the AFO group members were additionally provided with an ankle-foot orthosis and the walking support band group members received training wearing a walking support band. Before and after 4 weeks of treatment, all three groups were evaluated using three-dimensional gait analysis. Results:A total of 57 patients finished the study. After the interventions, the average step speed, frequency and step length of the three groups had all increased significantly, while the average stride width, the percentage of double stance phase, unaffected and affected side stance phase, and the ratio between unaffected and affected side stance phase had all decreased significantly. After the intervention, the average step speed, frequency and length of the AFO and walking support band groups had increased significantly compared with the conventional rehabilitation group, while the average stride width of the AFO group, and the stride width, the percentage of double stance phase and unaffected side stance phase of the walking support band group had decreased significantly. After the treatment, the average percentages of double stance phase and unaffected side stance phase of the walking support band group had decreased significantly more than in the AFO group.Conclusions:A walking support band can significantly improve the abnormal gait of stroke survivors and is superior to an ankle-foot orthosis when combined with conventional rehabilitation therapy.

Objective@#To study the application value of nerve root decompression through posterior approach in minimally invasive surgery of lumbar disc herniation (LDH).@*Methods@#From June 2016 to June 2018, 80 patients with unilateral single segment LDH were selected and diagnosed in Yunnan Puer People′s Hospital.The patients were divided into control group and observation group according to the random number table method, 40 cases in each group.The control group was treated with posterior fenestration and nucleus pulposus extraction, and the observation group was treated with posterior neurolysis and decompression through 5.3 mm intervertebral foramen.The incision length, operation time, intraoperative blood loss and postoperative hospital stay were compared between the two groups.The visual analog scale (VAS) of pain before operation and 1, 2, 7 days after operation was compared.The Japanese Orthopedic Association (JOA) score and the Oswestry disability index (ODI) questionnaire score before operation and 1, 3, 12 months after operation were compared.The effect of lumbar function recovery 12 months after operation was compared.@*Results@#The incision length, operation time, days in-hospital after operation, and bleeding amount in observation group were (0.9±0.2) cm, (50.8±8.6) min, (16.5±5.9) ml, (4.3±0.5)d, and in control group were (4.6±0.8) cm, (72.3±15.2) min, (52.5±10.3) ml, (7.2±0.9)d.The differences between the two groups were statistically significant (t=8.625, 14.623, 32.625, 6.524, all P<0.001). The VAS scores of the observation group and the control group were (5.7±1.1), (3.3±0.6), (1.2±0.3), (0.5±0.1) and (5.5±1.2), (4.2±0.8), (1.9±0.4), (1.1±0.3) before and 1, 3 and 7 days after the operation, respectively.The differences 1, 3, 7 days after operation between the observation group and the control group were statistically significant (all P<0.05). The JOA scores of the observation group were (8.1±1.6), (19.3±4.2), (23.2±4.9), (25.8±5.2) before and 1, 3 and 12 months after operation, respectively, and those of the control group were (8.3±1.5), (15.2±3.3), (19.3±4.2), (20.6±5.5) after operation.The differences 1, 3, 12 months after operation between the observation group and the control group were statistically significant (all P<0.05). The ODI scores of the observation group were (43.7±10.6), (18.3±5.2), (10.2±3.9), (1.8±0.5) before and 1, 3 and 12 months after the operation, respectively, and those of the control group were (42.5±9.4), (25.2±5.3), (14.3±4.2), (4.6±0.9) after the operation.The differences 1, 3, 12 months after operation between the observation group and the control group were statistically significant (all P<0.05). The effective rate of the observation group was significantly higher than that of the control group (92.5%(30/40) vs.75.0%(37/40), χ2=4.501, all P=0.034).@*Conclusion@#It can bring less trauma and faster recovery with 5.3mm intervertebral endoscopy by posterior approach of nerve root decompression for LDH patients, which is better safety and efficacy.

ABSTRACT

OBJECTIVE: To investigate the efficacy and safety of nebulized inhalation of terbutaline sulfate for injection in the treatment of children with wheezing disease. METHODS: From December 2016 to April 2018,440 cases of lower respiratory tract infection with cough and wheezing were hospitalized for treatment in the Department of Respiratory Medicine of Children's Hospital of Soochow University,Chengdu Women's & Children's Central Hospital and Dalian Children's Hospital of Dalian Medical University. The children were selected and randomly divided into terbutaline sulfate for injection group(Group A),terbutaline sulphate solution for nebulization group(Group B)and control group(Group C). The efficacy and adverse reactions of the three groups were compared. RESULTS: The scores of wheezing symptoms in group A and group B decreased more significantly than those in group C(P<0.05). Group A and group B had a certain influence on heart rate,and the heart rate at 30 minutes and 60 minutes after nebulization was higher than that of group C. In addition to the effect on heart rate,no other adverse reactions were found in group A and group C;one patient in the group B developed arm tremor and disappeared after stopping the drug. CONCLUSION: Inhalation of terbutaline sulfate for injection in the treatment of children with wheezing disease can shorten the treatment time and effectively improve the clinical treatment effect. The clinical efficacy is comparable to that of terbutaline sulphate solution for nebulization,and it is safe and worthy of clinical application.

ABSTRACT

In recent years, near-infrared spectroscopy has developed into an analytical technique widely used in various fields. Because of its advantages of fast, green and non-destructive, it plays an increasingly prominent role in the field of traditional Chinese medicine (TCM) analysis. However, due to the complexity and overlap of spectra, near-infrared spectroscopy needs to be combined with chemometrics for analysis and calculation. The principle, application scope, advantages and limitations of near infrared spectroscopy and chemometrics are summarized in detail, in addition, their combined applications in the identification of the origin, authenticity, processed products, composition prediction and water content detection of TCM are reviewed. The authors discussed and analyzed the joint application of near-infrared spectroscopy and chemometrics in the field of TCM analysis, and summarized the unique advantages of the combined technology in the field of TCM, which had certain guiding significance for medical workers to better use this technology.

ABSTRACT

OBJECTIVE@#To compare the clinical effects of total arthroscopic internal drainage and arthroscopic combined with posterior small incision in the treatment of popliteal cyst.@*METHODS@#From January 2015 to January 2017, 60 patients with popliteal cyst were treated, including 29 males and 31 females, aged 30 to 65(47.8±2.5) years old, with a course of disease (8.5±4.2) months. Among them, 30 cases received total arthroscopic internal drainage for popliteal fossa cyst(total arthroscopic group), 30 cases received arthroscopic combined with posterior small incision for popliteal fossa cyst(arthroscopic combined with small incision group). The operation time, intraoperative bleeding volume, incision length, Rauschning and Lindgren grade 0 recovery rate and Lysholm score were compared between the two groups.@*RESULTS@#Twenty-nine patients in total arthroscopy group were followed up, and 28 patients in arthroscopy combined with small incision group were followed up for 8 to 20(12.8±2.1) months. Operation time: total arthroscopic group(45.32±5.71) min, arthroscopic combined small incision group (44.56±3.85) min; Rauschning and Lindgren grade 0 recovery: 23 cases in total arthroscopic group, 22 cases in arthroscopic combined small incision group; postoperative Lysholm score: total arthroscopic group 84.5±11.2, arthroscopic combined small incision group 83.2±12.7; there was no significant difference between the two groups(>0.05). Intraoperative bleeding volume: total arthroscopic group(5.32±1.25) ml, arthroscopic combined small incision group(20.75±8.18) ml; incision length: total arthroscopic group (1.51±0.34) cm, arthroscopic combined small incision group (7.34±0.75) cm; the difference between the two groups was significant(<0.05). At the last follow-up, the knee joint was examined by magnetic resonance imaging, and no recurrence of cyst was found.@*CONCLUSIONS@#Total arthroscopic internal drainage and arthroscopic combined with posterior small incision technique for popliteal fossa cyst with intra-articular lesions have the same clinical effect, but less trauma and faster recovery.
