BACKGROUND:Ultrasonic therapy is one of several physical therapy modalities suggested for the management of pain and loss of function due to osteoarthritis. However, its effectiveness stil remains controversial in the previous studies.
OBJECTIVE:To analyze the effect of ultrasonic therapy for the treatment of relieving knee osteoarthritis pain.
METHODS:A retrieval of Pubmed, Ovid/Medline, Ovid/EMBASE, and Cochranee database was performed. The relevant literatures were manual y retrieved. The retrieval deadline was set on March 31, 2014. Randomized control ed trials on ultrasonic therapy of knee osteoarthritis were col ected.
RESULTS AND CONCLUSION:A total of eight studies of meta-analysis were accumulated. Among them, six studies adopted visual analog scale and Western Ontario and McMaster Universities Arthritis Index, one study adopted visual analog scale only, and one study adopted Western Ontario and McMaster Universities Arthritis Index. Then the Western Ontario and McMaster Universities Arthritis Index scores were transformed into visual analog scale scores for data analysis. There was a statistical difference between the groups in the visual analog scale pain score (standardized standard deviation:-0.51;95%confidence interval:-0.68,-0.33;P=0.05). Ultrasonic therapy is an effective method for knee osteoarthritis pain.

Objective To investigate the feasibility and the perioperative treatments of repairing atrial septal defects and bilateral lung transplantation in treatment of ASD with Eisenmenger's syndrome.Methods On May 24th,2016,one case of atrial septal defect with Eisenmenger's syndrome underwent repair for the atrial septal defect with bilateral sequential lung transplantation aided by extracorporeal circulation ECMO in Zhongshan People's Hospital.In strict accordance to the procedure,the lung was collected and preserved with the HTK solution.The operation went smoothly,the cold ischemic time for the right lung was 120 min and that for the left lung was 260 min.Postoperatively,Tacrolimus (FK506) + Mycophenolate Mofetil (MMF) + adrenal cortical hormone Sanlian immunosuppression was used.Results At 60th h post-operation the patient was hemodynamically stable,with good oxygenation after removal of the ECMO.At 7th day post-operation the patient was extubated.At 12th-20th day post-operation bacterial culture of the sputum was found to be positive and the patient was treated with the corresponding sensitive antibiotics and recovered.Cardiac ultrasound before discharge showed that there was no residual shunt.One month after discharge the cardiopulmonary function of the patient was quite good,chest X-ray showed that the bilateral transplanted lungs were clear and the patient's quality of life was much better.Conclusion Cardiac malformation repairs with bilateral lung transplantation is a feasible treatment for patients with end-stage Eisenmenger's syndrome with bi-directional shunts.The key to success is sufficient preoperative preparation,and a smooth operation with the timely and effective treatment of postoperative complications.

Improving medical students' calculation ability in statistics has become the focus and difficulty of medical statistics course teaching, and its application relies heavily on statistical calculation software. In order to explore a new teaching approach which combined the advantages of traditional method and web-based calculation, we intended to build a web computing platform applying the Browser/Server (B/S) mode based on the campus network, and to revise the current syllabus of medical statistics, as well as to create a virtual web-lab containing a typical case library. Practice has proved that the new mode effec-tively improved the practice capability of students and changed the traditional teacher-centered teaching approach.

BACKGROUND:Extensive studies have shown that transcutaneous electrical nerve stimulation (TENS) plays a positive role in relieving the pain caused by a variety of diseases. However, its exact effect to manage pain in patients with knee osteoarthritis is stil controversial. TENS is classified into h-TENS and l-TENS, but currently its respective role in relieving the pain caused by knee osteoarthritis is not clear yet. OBJECTIVE: To compare the efficacy of h-TENS and l-TENS on pain relieving among patients with knee osteoarthritis. METHODS: A computer-based search was performed on PubMed, Embase and Cochrane database for randomized controled trials on TENS for the treatment of knee pain in patients with knee osteoarthritis which were reported before February 2014. Methodology quality of the trials was criticaly assessed and relative data were extracted. These studies were selected independently by two reviewers according to the inclusion and exclusion criteria. Meta-analysis was performed using Revman5.2 software. RESULTS AND CONCLUSION:A total of 10 randomized controled trials involving 519 cases were included. The results of meta-analysis showed that the h-TENS group had significant effects on pain relief in knee osteoarthritis patients in comparison to the control group [MD=-0.56, 95%CI(-0.98,-0.15),P=0.008]; the l-TENS group had no significant effect on pain relief in knee osteoarthritis patients in comparison to the control group [MD=-0.13, 95%CI(-1.63, 1.38),P=0.87]; the h-TENS group had significant effect on pain relief in knee osteoarthritis patients in comparison to the l-TENS group [MD=-0.85, 95%CI(-1.32, -0.37), P=0.000 5]. These findings indicate that h-TENS performs something positive to reduce pain in knee osteoarthritis patients that l-TENS cannot do. Owing to the limitations of this study, further work is needed to determine the role of TENS in pain management among patients with knee osteoarthritis.

OBJECTIVETo analyze the effects of Ling Qi Juan Gan capsule drug-containing serum at different concentrations on the platelet-derived growth factor (PDGF)-induced proliferative capabilities of and JAK2 and p-STAT3 protein expression in hepatic stellate cells (HSC) using an in vitro system.

METHODSTwenty-five Sprague-Dawley rats were randomly divided into five equal groups for intragastric administration of physiological saline (10 ml/kg; group A), Fufang Biejia Ruangan tablet solution (1.5 g/kg; group B), or Ling Qi Juan Gan capsule solution at low dose (2.125 g/kg; group C1), mid dose (4.25 g/kg; group C2), or high dose (8.5 g/kg; group C3). The post-administration serum isolated from each rat (200 ml/L) was used to treat the HSC-T6 cell line following induction by PDGF (10 ng/ml). At 24, 48 and 72 h post-exposure, the cells' proliferation was measured using the Cell Counting Kit-8 (CCK-8) colorimetric assay. In addition, at 24 h post-exposure the expression of JAK2 and p-STAT3 was measured by western blotting (expressed as grey scale intensity). Multiple group comparison of repeated measures data was made by one-way ANOVA with Student-Newman-Keuls post hoc test.

RESULTSCompared to group A, groups C2 and C3 had significantly higher inhibited proliferation at all post-exposure time points examined (24 h: A = 1.550 +/- 0.065, C2 = 1.335 +/- 0.106, C3 = 1.241 +/- 0.205; 48 h: A = 1.311 +/- 0.650, C2 = 1.090 +/- 0.106, C3 = 0.909 +/- 0.191; 72 h: A = 1.039 +/- 0.103, C2 = 0.719 +/- 0.116, C3 = 0.641 +/- 0.110, F = 36.292, all P less than 0.05); in contrast, compared to group A, group C1 showed no inhibition of proliferation at 24 h (1.522 +/- 0.128, P = 0.717) but showed significantly higher inhibition of proliferation at 48 h and 72 h (1.153 +/- 0.183 and 0.753 +/- 0.210, respectively, F = 36.292, P less than 0.05). Compared with group A, all Ling Qi Juan Gan capsule-containing serum-treated groups showed significantly lower expression of both JAK2 (A = 1.605 +/- 0.024 vs. C1 = 1.170 +/- 0.042, C2 = 0.842 +/- 0.036, C3 = 0.555 +/- 0.036, F = 43.091) and p-STAT3 (A = 1.401 +/- 0.030 vs. C1 = 1.229 +/- 0.025, C2 = 0.668 +/- 0.034, C3 = 0.630 +/- 0.026, F = 78.426, all P less than 0.01).

CONCLUSIONLing Qi Juan Gan capsule drug-containing serum can inhibit the proliferation of HSC-T6 cells in a dose-dependent manner and cause an overall decrease in the expression of JAK2 and p-STAT3 in activated HSC, thereby leading to a suppression of the JAK/STAT signal transduction pathway.

BACKGROUND:Reconstruction of the anterior cruciate ligament has become the gold-standard treatment for an anterior cruciate ligament rupture. Despite the popularity of the procedure, there remains a considerable amount of controversies over whether an autograft or anal ograft should be used for primary anterior cruciate ligament reconstruction. OBJECTIVE:To compare the clinical outcomes of al ograft and autograft in primary anterior cruciate ligament reconstruction. METHODS:Randomized control ed trials concerning autograft versus non-irradiated al ograft for anterior cruciate ligament reconstruction were identified from the PubMed/Medline database conducted up to July 12, 2014. These studies were selected independently by two reviewers according to the inclusion and exclusion criteria. Meta-analysis was performed using Revman5.2 software. RESULTS AND CONCLUSION:A total of 6 randomized control ed trials consisting of 858 cases were included, 441 cases in autograft group and 417 cases in non-irradiated al ograft. The results of the meta-analysis indicate no significant difference between autografts and non-irradiated al ografts in overal IKDC [relative risk (RR)=1.02, 95%confidence interval (CI) (0.99 to 1.06), P=0.21], degree of laxity [mean difference (MD)=-0.13, 95%CI (-0.29 to-0.02), P=0.09], Lachman test [RR=1.04, 95%CI (0.95 to 1.13), P=0.37], pivot shift test [RR=1.00, 95%CI (0.95 to 1.05), P=0.96], one-leg hop test [RR=1.01, 95%CI (0.96 to 1.06), P=0.77], Lysholm score [MD=-0.64, 95%CI (-1.45 to 0.17), P=0.12], Tegner score [MD=0.16, 95%CI (-0.16 to 0.47), P=0.34] and rate of postoperative complications [RR=1.42, 95%CI (0.67 to 3.04), P=0.36]. Therefore, in the meta-analysis, there is no significant difference between autograft and non-irradiated al ograft in clinical outcomes. However due to the limitations of our study, further work is needed to determine this conclusion.

BACKGROUND:Symptomatic treatment is the main management strategy for patients with knee osteoarthritis at early metaphase. Some previous studies have demonstrated that neuromuscular electrical stimulation can al eviate pain in knee osteoarthritis patients. To date, this effectiveness, however, stil remains controversial.
OBJECTIVE:To assess the efficacy of neuromuscular electrical stimulation on pain in patients with knee osteoarthritis.
METHODRandomized control ed trials concerning the efficacy of neuromuscular electrical stimulation in the treatment of knee osteoarthritis were identified from the Medline database conducted up to July 3, 2014. These studies were selected independently by two reviewers according to the inclusion and exclusion criteria. Meta-analysis was performed using Revman5.2 software.
RESULTS AND CONCLUSION:A total of 5 randomized control ed trials consisting of 239 participants were included. The results of the meta-analysis indicate neuromuscular electrical stimulation has no significant impact on measure of pain in knee osteoarthritis patients in comparison to the blank control group [mean difference=-0.40, 95%confidence interval (-1.34-0.54), P=0.40]. Owing to the sample limitations of our study, it is hard for us to draw a conclusion that the application of neuromuscular electrical stimulation in managing pain in patients with knee osteoarthritis is of little significance. Further work based on large-sample and high-quality randomized control ed trials is needed to determine the role of neuromuscular electrical stimulation in pain in this population.
