ABSTRACT

OBJECTIVE@#To investigate the effects of paclitaxel, quizartinib and their combination on proliferation, apoptosis and FLT3/STAT5 pathway of human leukemia cell line MV4-11 (FLT3-ITD+).@*METHODS@#MV4-11 cells were treated with paclitaxel and quizartinib at different concentrations for 24 h, 48 h and 72 h, respectively, and then the two drugs were combined at 48 h to compare the inhibition of proliferation, the apoptosis rate was detected by flow cytometry, the expression of FLT3 and STAT5 mRNA was determined by fluorescence quantitative PCR, and the protein expression of FLT3, p-FLT3, STAT5 and p-STAT5 was determined by Western blot.@*RESULTS@#Different combination groups of paclitaxel and quizartinib had synergistic inhibitory effect. The cell survival rate in the combination group was significantly lower than that in the single drug group (P<0.05). The cell apoptosis rate in the combination group was significantly higher than that in the single drug group (P<0.001). The expression of FLT3 mRNA in combination group was significantly higher than that in two single drugs (P<0.01). The expression of STAT5 mRNA in combination group was significantly higher than that in quizartinib group (P<0.001); increased compared with paclitaxel group, but there was no statistical significance. The expression level of p-FLT3、p-STAT5 protein in the combination group was significantly lower than that in the single drug group (P<0.05, P<0.05).@*CONCLUSION@#Paclitaxel combined with quizartinib can synergistically inhibit the proliferation of MV4-11 cell line and promote the apoptosis of MV4-11 cell line by inhibiting the activity of FLT3/STAT5 pathway.

ABSTRACT

OBJECTIVE@#To investigate the clinical effect of arthroscopic fixation of tibial avulsion fracture of posterior cruciate ligament with a knot-free anchor and Endobuton titanium plate.@*METHODS@#From October 2019 to October 2020, 12 patients with tibial avulsion fracture of posterior cruciate ligament were treated with the arthroscopic knot-free anchor and Endobuton titanium plate, including 9 males and 3 females. The age ranged from 23 to 58 years old. The time from injury to operation ranged from 2 to 9 days. There were 2 cases of Meyers typeⅡand 10 cases of Meyers type Ⅲ. There were 2 cases of meniscus injury and 1 case of partial injury of medial collateral ligament. The fracture healing and knee range of motion were evaluated after operation, and the clinicalefficacy was evaluated by Lysholm function score.@*RESULTS@#All patients were followed up for 12 months. All patients healed within 6 months, and there were no complications such as incision infection, lower extremity deep venous thrombosis and internal fixation falling off. The knee flexion range of motion recovered from 50°-90° before operation to 115°-130° 6 months after operation, and no patient had straightening disorder. Lysholm functional score recovered from preoperative 29-54 scores to 86-100 scores 12 months after operation.@*CONCLUSION@#Arthroscopic reduction and fixation of tibial avulsion fracture of posterior cruciate ligament with the knot-free anchor and Endobuton titanium plate has less complications, high fracture healing rate, good extension and flexion angle and early function recovery of knee joint.

ABSTRACT

ABSTRACT Purpose: To investigate the impact of different sizes of steep meridian clear corneal incisions for phacoemul sification on anterior corneal higher-order aberrations. Methods: Medical records of patients who underwent 2.2-mm coaxial micro-incision cataract surgery or 2.75-mm coaxial small-incision cataract surgery were retrospectively reviewed. Only patients with preexisting anterior corneal astigmatism <2.00 diopters (D) and ≥0.50 D who underwent a steep meridian clear corneal incision were included. Primary outcomes were 3rd- to 6th-order anterior corneal higher-order aberrations with an 8-mm pupil. Anterior corneal astigmatism and effective phaco time were evaluated as secondary outcomes. Preoperative and 3-month postoperative outcomes were evaluated. Results: Anterior corneal astigmatism significantly decreased after both procedures; however, there was no significant difference found in surgically induced anterior corneal astigmatism between the two procedures (p=0.146). Although the total higher-order aberrations did not significantly change after both procedures, the group comparison showed a significant difference in surgically induced total higher-order aberrations (a decrease of 0.337 ± 1.156 mm in 2.2-mm coaxial micro-incision cataract surgery and an increase of 0.106 ± 0.521 mm in 2.75-mm coaxial small-incision cataract surgery, p=0.046). Spherical aberrations significantly decreased after 2.2-mm coaxial micro-incision cataract surgery (p=0.001), whereas they did not change significantly after 2.75-mm coaxial small-incision cataract surgery (p=0.564). Coma did not significantly change after either of the procedures. Trefoil did not significantly change after 2.2-mm coaxial micro-incision cataract surgery (p=0.361), whereas it significantly increased after 2.75-mm coaxial small-incision cataract surgery (p<0.001). There was no significant difference shown in effective phaco time between the procedures. A significantly positive correlation was shown between surgically induced anterior corneal astigmatism and coma in 2.75-mm coaxial small-incision cataract surgery (r=0.387, p=0.006). There was no significant correlation found between any surgically induced higher-order aberration changes and effective phaco time. Conclusions: The results showed that 2.2-mm coaxial micro-incision cataract surgery and 2.75-mm coaxial small-incision cataract surgery did not significantly degrade the total higher-order aberrations of the anterior cornea. However, the surgically induced changes in total higher-order aberration showed a significant difference between the two procedures, with a slight reduction after 2.2-mm coaxial micro-incision cataract surgery and a slight increase after 2.75-mm coaxial small-incision cataract surgery. Phaco time and power used during surgery had no impact on corneal aberrations.


RESUMO Objetivo: Investigar o impacto de diferentes ta manhos de incisões em córnea clara com meridiano íngreme para facoemulsificação com aberrações de mais alta ordem da córnea anterior. Métodos: Foram retrospectivamente revisados os prontuários médicos de pacientes que se submeteram a cirurgias de catarata com microincisões coaxiais de 2,2 mm ou com incisões coaxiais pequenas de 2,75 mm. Foram apenas incluídos pacientes com astigmatismo preexistente da córnea anterior <2,00 dioptrias (D) e ³0,50 D, e submetidos a incisões em córnea clara com meridiano íngreme. Os desfechos primários foram aberrações da córnea anterior da 3ª à 6ª ordem com uma pupila de 8 mm. O astigmatismo da córnea anterior e o tempo efetivo de facoemulsificação foram avaliados como desfechos secundários. Os desfechos pré-operatório e pós-operatório aos 3 meses também foram avaliados. Resultados: O astigmatismo da córnea anterior diminuiu significativamente após ambos os procedimentos, mas não se encontrou nenhuma diferença significativa entre os dois procedimentos quanto ao astigmatismo da córnea anterior, induzido pela cirurgia (p=0,146). Embora as aberrações totais de mais alta ordem não se tenham alterado significativamente após ambos procedimentos, a comparação entre os grupos revelou uma diferença significativa nas aberrações totais de mais alta ordem, induzidas pela cirurgia (uma diminuição de 0,337 ± 1,156 mm na cirurgia de catarata por microincisão coaxial de 2,2 mm e um aumento de 0,106 ± 0,521 mm na cirurgia de catarata por incisão coaxial pequena de 2,75 mm; p=0,046). A aberração esférica diminuiu significativamente após cirurgia de catarata por microincisão coaxial de 2,2 mm (p=0,001), mas não se alterou significativamente após cirurgia de catarata por incisão coaxial pequena de 2,75 mm (p=0,564). A aberração de coma não mudou significativamente após qualquer dos procedimentos. O trifólio não se alterou significativamente após cirurgia de catarata por microincisão coaxial de 2,2 mm (p=0,361), mas aumentou significativamente após cirurgia de catarata por incisão coaxial pequena de 2,75 mm (p<0,001). Nenhuma diferença significativa se evidenciou quanto ao tempo efetivo de faco-emulsificação entre os dois procedimentos. Houve uma correlação positiva significativa entre o astigmatismo da córnea anterior, induzido pela cirurgia e a aberração de coma na cirurgia de catarata por incisão coaxial pequena de 2,75 mm (r=0,387, p=0,006). Não foi encontrada correlação significativa entre as alterações nas aberrações totais de mais alta ordem, induzidas pela cirurgia e o tempo efetivo de faco-emulsificação. Conclusões: Nem a cirurgia de catarata por microincisão coaxial de 2,2 mm, nem aquela por incisão coaxial pequena de 2,75 mm degradaram significativamente as aberrações totais de mais alta ordem da córnea anterior. Porém, as alterações nas aberrações totais de mais alta ordem, induzidas pela cirurgia mostraram uma diferença significativa entre os dois procedimentos, com uma ligeira redução na cirurgia de catarata por microincisão coaxial de 2,2 mm e um pequeno aumento na cirurgia de catarata por incisão coaxial pequena de 2,75 mm. O tempo de facoemulsificação e a potência utilizada durante a cirurgia não tiveram impacto nas aberrações corneanas.

ABSTRACT

@#Objective To observe effects of the electroacupuncture combined with music therapy on cerebral neurometabolites measured with magnetic resonance spectroscopy in patients with post-stroke depression.Methods From January, 2013 to December, 2017, 60 patients with post-stroke depression were randomly divided into drug group (n=30) and electroacupuncture music group (n=30). Another 20 cases of normal control group were recruited. The concentration of N-acetylaspartate (NAA), creatine (Cr) and choline (Cho) in the bilateral prefrontal white matter was measured with magnetic resonance spectroscopy before and after eight-week treatment in three groups. The clinical efficiency was defined as the different of Hamilton Depression Rating Scale before and after treatment.Results There was no significant difference in the effective rate between two treatment groups (Z=-0.145, P>0.05). Before treatment, the Cho/Cr was lower in the electroacupuncture music group and the drug group than in the normal control group (t>3.093, P<0.05). After treatment, the Cho/Cr increased in both treatment groups (t>2.219, P<0.05), and no significant difference was found between them (P>0.05).Conclusion The choline level may be the neurobiochemical basis for glial cell or myelin sheath function and integrity in white matter of patients with post- stroke depression. The regulation of glial cell and myelin function in prefrontal white matter may be one of the action targets of electroacupuncture combined with music therapy.

ABSTRACT

Objective To investigate the effects of nicorandil on hypoxia-inducible factor (HIF)-1α mRNA and protein in lung tissue of one-lung ventilation.Methods Twenty-four clean New Zealand white rabbits were randomly divided into sham group (group S) (two-lung ventilation+thoracotomy),negative control group (group C) (one-lung ventilation + thoracotomy + saline),nicorandil group (group N) (one-lung ventilation+ thoracotomy+ nicorandil) and antagonist group (group J) (one-lung ventilation + thoracotomy + nicorandil + glibenclanide) equally.The implementation of mechanical ventilation depended on self-made double-lumen endotracheal tube after intravenous induction through ear marginal vein.Intravenous maintenance medicine was infused by trace injection pump after anesthesia induction.The implementation of thoracic surgery was simulated through one-lung and two-lung ventilation by auscultation,bubble test and direct observation.Group S was given anaesthesia only,no one-lung ventilation group S,the other three groups had single lung ventilation,and the drug was injected before the operation.Group N was infused nicorandil 100 ptg· kg-1 · h-1 before the implementation of single lung ventilation for 1 h.Group C was injected with the same amount of normal saline.Group J was intravenous infusion of glibenclamide 75 μg· kg-1 · h-1 and nieorandil 100μg · kg-1 · h-1 the implementation of single lung ventilation for 1 h.Then wet and dry weight ratio(W/D) and superoxide dismutase (SOD) activity were measured after non-ventilatory lung was processed and preserved.The expression of HIF-1α protein of non ventilatory lung tissue was detected by Western-blot in the four groups.The transcription of HIF-1α mRNA was detected by real-time quantitative real-time PCR (qRT-PCR) in all groups.Results W/D in groups C and J were significantly higher compared with that of groups S and N (P<0.05).The activity of SOD in groups C and J was significantly lower compared with groups S and N (P<0.05).The expression of HIF1α protein and transcription of HIF-1α mRNA in groups C,N and J were significantly higher than those in group S,and that of group N was significantly higher than those of groups C and J (P<0.05).Conclsion Nicorandil has a protective effect on the collapse and inflation of non-ventilatory lung in rabbit with one-lung ventilation,reducing oxidative stress by SOD,acting on mito KATP and coming into play by up-regulation of HIF-1α.

ABSTRACT

The current proxy indicators and quantitative strategy were summarized for cognitive reserve,the findings of cognitive reserve was discussed then in brain aging and Alzheimer's disease,and some future research directions were presented about cognitive reserve.The reserve of brain explains the disjunction between clinical symptoms and the degree of brain damage,whereby some people can tolerate more of age-related or Alzheimer's disease pathology than others and maintain brain function.The cognitive reserve hypothesis has been widely used in epidemiological and neuroimaging studies,but it lacks a unified quantitative indicator.The future research of cognitive reserve should be focused on the development of quantitative indicators that cover a variety of potential factors dynamically.

ABSTRACT

Mild cognitive impairment (MCI) is a prodromal stage of dementia.Predicting MCI's conversion to Alzheimer's disease (AD) plays critical roles in preventing the progression of AD.Alzheimer's disease neuroimaging initiative (ADNI) was introduced briefly,which was a widely used neuroimaging database for the study on AD related diseases,and the application of machine learning algorithm was reviewed in MCI classification.Deep learning network,which transforms the original data into a higher level and more abstract expression,has shown great promise in MCI conversion and classification.Two main kinds of deep learning approaches were described,including supervised learning and unsupervised learning,and their new application was discussed in MCI conversion and classification based on structural magnetic resonance imaging (sMRI).Finally,the current limitations and future trends of deep learning in this area were explored.

ABSTRACT

<p><b>BACKGROUND</b>Volumetric-modulated arc therapy (VMAT) can only be implemented on the new generation linacs such as the Varian Trilogy® and Elekta Synergy®. This prevents most existing linacs from delivering VMAT. The purpose of this study was to investigate the feasibility of using a conventional linear accelerator delivering constant dose rate and constant angular spacing intensity-modulated arc therapy (CDR-CAS-IMAT) for treating cervical cancer.</p><p><b>METHODS</b>Twenty patients with cervical cancer previously treated with intensity-modulated radiation therapy (IMRT) using Varian Clinical 23EX were retreated using CDR-CAS-IMAT. The planning target volume (PTV) was set as 50.4 Gy in 28 fractions. Plans were evaluated based on the ability to meet the dose volume histogram. The homogeneity index (HI), target volume conformity index (CI), the dose to organs at risk, radiation delivery time, and monitor units (MUs) were also compared. The paired t-test was used to analyze the two data sets. All statistical analyses were performed using SPSS 19.0 software.</p><p><b>RESULTS</b>Compared to the IMRT group, the CDR-CAS-IMAT group showed better PTV CI (0.85 ± 0.03 vs. 0.81 ± 0.03, P = 0.001), clinical target volume CI (0.46 ± 0.05 vs. 0.43 ± 0.05, P = 0.001), HI (0.09 ± 0.02 vs. 0.11 ± 0.02, P = 0.005) and D95 (5196.33 ± 28.24 cGy vs. 5162.63 ± 31.12 cGy, P = 0.000), and cord D2 (3743.8 ± 118.7 cGy vs. 3806.2 ± 98.7 cGy, P = 0.017) and rectum V40 (41.9 ± 6.1% vs. 44.2 ± 4.8%, P = 0.026). Treatment time (422.7 ± 46.7 s vs. 84.6 ± 7.8 s, P = 0.000) and the total plan Mus (927.4 ± 79.1 vs. 787.5 ± 78.5, P = 0.000) decreased by a factor of 0.8 and 0.15, respectively. The IMRT group plans were superior to the CDR-CAS-IMAT group plans considering decreasing bladder V50 (17.4 ± 4.5% vs. 16.6 ± 4.2%, P = 0.049), bowel V30 (39.6 ± 6.5% vs. 36.6 ± 7.5%, P = 0.008), and low-dose irradiation volume; there were no significant differences in other statistical indexes.</p><p><b>CONCLUSIONS</b>Patients with cervical cancer treated with CDR-CAS-IMAT using Varian Clinical 23EX can get equivalent or superior dose distribution compared to those treated with IMRT. CDR-CAS-IMAT has a less treatment time and MU, which can reduce the uncertainty factor and patient discomfort in treatment.</p>

ABSTRACT

Objective To evaluate the diagnostic value of high-frequency ultrasound in the diagnosis of supinator syndrome (SD). Methods Ten patients with supinator syndrome (SD group) and 20 healthy volunteers (control group) underwent ultrasonographic examination. Axial and long-axis views of the radial nerve were taken where the nerves enters the supinator muscle entrance. The maximum transverse diameter and anteroposterior diameter were also measured. Results High-frequency ultrasound clearly revealed the images and course of radial nerve deep branch in two groups. The SD group had swollen nerves and the maximum transverse diameter and anteroposterior diameter were (3.50?0.39)mm and (4.30?0.47)mm,respectively,which were significantly larger than in the control group [(1.10?0.17)mm,t=-29.67,P=0.00;(1.00?0.16)mm,t=-36.72,P=0.00). The causes (including synovial cyst nearby and radial artery recurrent branch) of nerve entrapment were revealed directly in 4 patients in SD group. Conclusions High-frequency ultrasound can clearly display the radial nerve deep branch around the elbow joint. SD patients have swollen nerves at the entrance of the supinator muscle,where the diameters of these nerves are abnormally enlarged.

ABSTRACT

Objective ToinvestigatetherelationshipbetweenmuscleRASoncogenehomolog (MRAS)genepolymorphismandyoungpatientswithischemicstroke.Methods Atotalof243young patients with ischemic stroke from Nanjing Stroke Registry Program from December 2009 to October 2012 were enrolled retrospectively. At the same time,512 age-and sex-matched healthy controls were selected. The polymorphisms of MRAS genes rs3755751 and rs9289559 loci were analyzed by the modified multiplex PCR-ligase detection reaction assay. The genotype of each locus and the allele frequencies were analyzed and compared. Results (1)The frequencies of AA,AG and GG genotypes for rs3755751 in the stroke group (n=243)were 7. 4%(n=18),37. 0%(n=90),and 55. 6%(n=135),respectively. There were no significant differences compared with those (6. 4%[n=18],36. 9%[n=189]and 56. 6%[n=190]) in the control group (n=512)(P>0. 05). The frequencies of AA,AG and GG genotypes for rs9289559 in stroke group were 7. 0 (n=17)%,42. 0%(n=102),and 51. 0%(n=124),respectively. There were no significant differences compared with 6. 1%,(n=31)37. 9%(n=194),and 56. 1%(n=287)in the control group (P>0. 05). (2)Further construction of an effect model (AA vs. AG+GG and GG vs. AG+AA),there was no significant difference between the stroke group and the control group (P >0. 05 ). Analyzing the effects of different genotypes on plasma lipid levels showed that the high-density lipoprotein cholesterol level of the GG genotype subgroup in the young ischemic stroke group was significantly higher than that rs3755751 of the AG +AA genotype subgroup (OR,6. 80,95%CI 2.18-21.27, P=0. 001 ). Conclusions MRAS gene polymorphism may have no significant correlation with the genetic susceptibility in young patients with ischemic stroke. Polymorphism of rs3755751 may be correlated with the level of serum high-density lipoprotein cholesterol.

ABSTRACT

Objective The relationship between hypertension ( HTN) and ischemic stroke recurrence is unclear , but there may be different effects of HTN on the risk of recurrence .This study aims to explore whether HTN contributes differently to the recur-rence among subtypes of ischemic stroke ( IS) . Methods We eventually enrolled 1114 patients with ischemic stroke from Jul 2008 to Dec 2012 registered in Nanjing Stroke Registry Program (NSRP) in this study.All the patients were classified according to Trial of Org 10172 in Acute Stroke Treatment (TOAST) criteria: 315 (28.3%) patiwnts were classified as Large-artery atheroselerosis (LAA), 212 (19.0%) as cardioembolism (CE), 266 (23.9%) as small-artery occlusion (SAO), and 321 (28.8%) as other de-termined and undetermined etiologies ( Other) .The association between HTN and stroke recurrence in patients with different IS sub-types was analyzed using multivariate Cox regression analysis . Results The average follow-up duration was (19.4 ±10.3) months. Of 1114 patients with IS, 158 (14.2%) patients experienced a recurrent stroke .Patients with HTN had a significantly higher stroke recurrence rate than those without (16.5%vs 10.5%, P<0.05).Multivariate Cox regression analysis indicated that HTN increased the risk of ischemic stroke recurrence (HR=1.722, 95%CI:1.181-2.512, P=0.005).After stratification by TOAST subtypes, analysis revealed an association between HTN and stroke recurrence in LAA( HR=3 .767, 95%CI:1.866-7.585, P=0.001) and SAO (HR=3.530, 95%CI:1.156-12.740, P=0.028), but not in the other subtypes (CE: HR=0.773, 95%CI:0.370-1.615, P=0.493;Other:HR=1.498, 95%CI:0.590-3.807, P=0.395). Conclusion HTN is an independent risk factor for recurrent ischemic stroke and is related to the recurrent ischemic stroke in patients with large-artery and small-vessel disease .

ABSTRACT

BACKGROUND:Rheumatoid arthritis is an autoimmune disease, and traditional treatment methods are difficult to effectively solve the patient's lack of immune tolerance mechanisms. With the development of stem cel s in regenerative medicine, stem cel therapy has become a hot spot in the treatment of autoimmune diseases. Currently, studies on cel transplantation for the treatment of rheumatoid arthritis are rarely reported. OBJECTIVE:To study the influence of umbilical cord mesenchymal stem cel therapy on the changes of Th1/Th2 and Treg in rheumatoid arthritis patients, thereby seeking new therapies for rheumatoid arthritis. METHODS:We selected 180 cases of rheumatoid arthritis, including 27 patients as control group undergoing non-steroidal anti-inflammatory drugs and anti-rheumatic drugs and 153 patients as cel treatment group undergoing intravenous infusion of 40 mL umbilical cord mesenchymal stem cel s at a density of 4×107. Dosing regimen was same in the two groups. The 76 of 153 patients accepted second cel therapy at 3-4 months after the first cel therapy. After fol ow-up of 3 and 6 months, clinical effectiveness evaluation (DAS28, HAQ, ACR20), rheumatoid factor, anti-CCP antibodies, T cel subsets, Th cytokine were detected;for patients with second cel therapy, T cel subsets and Treg were detected at 8 months after treatment. RESULTS AND CONCLUSION:(1) At 3 months after treatment, the DAS28, HAQ and ACR20 scores were significantly lower in the cel treatment group than the control group (P0.05). (5) B cel levels were significantly decreased at 6 months after treatment (P>0.05);the rheumatoid factor value was significantly decreased at 3-6 months after treatment (P<0.05). (6) There was no change in anti-CCP antibody and interleukin-17 levels at 3-6 months after treatment. These findings indicate that after treatment with umbilical cord mesenchymal stem cel s, the Th1/Th2 tends to balance and Treg level is elevated in rheumatoid arthritis patients, which are directly related to clinical trials and symptomatic relief. Therefore, standard rheumatism medication combined with umbilical cord mesenchymal stem cel transplantation can improve immune network effects, adjust the immune tolerance and prevent il ness progress in rheumatoid arthritis patients.

ABSTRACT

To study the umbilical cord mesenchymal stem cells impact of inflammatory factors in rheumatoid arthritis patients.Methods:94 cases of patients with RA hospitalized in our department from April 2011 to December 2012 were treated with umbilical cord mesenchymal stem cells (MSCs) UC,during which the cell therapy scholastic ethics was committed approvally and patients′informed consents were separately signed .94 patients were directly intravenous infusion with 40 ml UC-MSCs ( 4×107 cells/ml),including 57 cases with two UC-MSCs therapy.We used multifunctional flow lattice Luminex 200 analysis to detect contents of 13 kinds of factors in serum such as TNF alpha,IFN-gamma,IL-1β,IL-4,IL-6,IL-8,IL-10,ie,and detected CPR,ESR,assessment DAS28,HAQ,and ARA.Follow-up treatments were performed after 1 week,3 months,6 months ( two cells treatment of 60 cases).Results:①DAS28,HAQ grading standards,were decreased (P<0.01) in 3 months and 6 months before the patients treatment ,2 times than one continue treatment decreased ( P<0.01 );the ESR and CRP in 1 week dropped significantly after treatment ( P<0.01),3 months,6 months before the treatment also decreased (P<0.05).②IL-6,TNF alpha were in falling levels after 1 week,3 months and 6 months treatment ,( P<0.05 ).Conclusion: We proved the inflammatory factors directly related with clinical indicators and symptoms of RA patients .94 cases of patients with other inflammatory factor (IL-17,IL-4,IL-10,etc.) also had some change,we still needed further observation.According to drug rheumatism guide at the same time , collaborative using with UC-MSCs could make RA patients improve local and systemic inflammatory response ,prevent disease progression.

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the clinical efficacy of the conventional acupuncture on knee osteoarthritis (KOA).</p><p><b>METHODS</b>Seventy-three cases of KOA were treated with the conventional acupuncture therapy at Liang-qiu (ST 34), Dubi (ST 35), Zusanli (ST 36), Yanglingquan (GB 34), Yinlingquan (SP 9), etc. The conventional acupuncture therapy lasted for 4 weeks (at least 3 treatments and less than 5 times each week). At the end of treatment, the follow-up visit lasted for 4 weeks. The Western Ontario and McMaster Universities osteoarthritis index (WOMAC) and the visual analogue scale (VAS) were adopted for the efficacy assessments of the patients.</p><p><b>RESULTS</b>Of 73 cases, 49 cases accomplished the trial. The data of the lost cases were included in the final data analysis. At the end of 4-week treatment and the follow-up visit, every score in VAS and WOMAC was decreased The conventional acupuncture therapy reduces the joint pain for apparently (P < 0.001, P < 0.05).</p><p><b>CONCLUSION</b>the patients with KOA and improves the joint function. The 4-week follow-up visit indicates that the efficacy of acupuncture is still sustained.</p>
