To analyze the indications and dominant diseases of acupotomology by literature research. The findings reveal that the 64.4% of all literature focused on eight categories of diseases, including the third lumbar vertebrae transverse process syndrome, tendinitis stenosans, cervical spondylosis, heel pain, scapulohumeral periarthritis, external humeral epicondylitis, lumbar disc herniation and osteoarthritis. The 87.5% of all literature focus on diseases of chronic strain of movement system, cervical spondylosis, cervicogenic disease, lumbar disc herniation and osteoarthritis. The indications of acupotomology are various, but not evenly distributed; the dominant diseases are comparatively concentrated. The acupotomology has great potential to treat the indications and dominant diseases. Therefore, acupotomology should be promoted scientifically in the future.

Conclusion HPLC method is accurate and reliable, and can be used for the quality control of Rhei Radix et Rhizoma and provide references for the authenticity of Rhei Radix et Rhizoma.

Objective To investigate the pathogenesis of osteoarthritis and feasibility of acupotomy therapy through the observation on the influences of acupotomy therapy on ethology and morphology in rabbits with knee osteoarthritis.Methods The model of knee osteoarthritis was established by applying the fixed method of knee extension posture in rabbits. The therapy of electro-acupuncture and acupotomy therapy were used to treat the rabbits. After 3 weeks the knee joint function was observed and reviewed based on Lequesne algofunctional index. The light microscope was used to observe tibia tissue after HE staining. The transmission electron microscope (TEM) was used to observe the internal femoral condyle cartilage.Results Lequesne algofunctional index showed that in local reaction, gait reaction and joint motion there was a significant different between the electro-acupuncture group or acupotomy group and the normal group or model group (P<0.05), respectively, while there was no different between the electro-acupuncture group and acupotomy group (P>0.05). HE staining showed that the cartilage injury was relieved and tended to recovery in the electro-acupuncture group and acupotomy group. The result of TEM showed that the lesion of cartilage cells and disorder of collagen fibrils were relieved in the acupotomy group, which is similar to those in the electro-acupuncture group.Conclusion The acupotomy therapy has a good curative effect on knee osteoarthritis, which is proved at macroscopic and microscopic levels.

OBJECTIVETo investigate the expression of microRNA-155 and microRNA-146a in the CD19(+) B cells of chronic lymphocytic leukemia (CLL), mantle cell lymphoma (MCL), splenic marginal zone lymphoma (SMZL), and to analyze its clinical significance.

METHODSPeripheral blood (PB) (78 cases) and bone marrow (BM) samples (9 cases) from 53 CLL patients, 13 MCL patients, 19 SMZL patients, and 12 healthy donors were collected. Mononuclear cells were isolated and B cells were purified with a CD19(+) magnetic-bead system. Total RNA was extracted from purified CD19(+) cells and microRNAs expression were measured using the TaqMan microRNA quantitative PCR. The results combined with the clinic data of patients were analysed.

RESULTS(1) The expression of microRNA-155 in CLL (4.49 ± 0.83) was significantly higher than in MCL (3.83 ± 0.45) and SMZL (3.80 ± 0.61) (P < 0.05); (2) The level of microRNA-146a in SMZL (3.81 ± 0.59) was significantly higher than in CLL (2.58 ± 0.90) and MCL (2.27 ± 0.88) (P < 0.01); (3) The level of microRNA-155 was significantly higher in IgVH unmutated patients than in mutated patients in CLL (P = 0.012); (4) The microRNAs expression had no statistical difference between two prognostic groups in CLL.

CONCLUSION(1) The expression of microRNA-155 and microRNA-146a is different in malignant lymphoproliferative disorders (LPD); (2) Deregulation of the microRNAs expression might play a critical role in the pathogenesis and prognosis in the LPD.

This study was to aimed investigate the influence of immunomagnetic sorting on detecting the genetic aberrations of multiple myeloma (MM) by interphase fluorescence in situ hybridization (FISH) and to explore the detection method suitable to use in our country. The genetic aberrations of immunomagnetically sorted and unsorted bone marrow cells from the same MM patients were detected by interphase FISH and the detectable rate of genetic aberration was compared. The types of probes included 13 q14 (RB-1) and 14q32 (IGH). The 42 and 22 sorted and unsorted marrow samples from MM patients were detected by using 13q14 probe and 14q32 probes respectively, the results indicated that the 13q14 deletion was found in 9 of 42 (21.4%) unsorted marrow samples and in 25 of 42 (56.8%) CD138(+)-sorted marrow samples. The 13q32 rearrangement was found in 7 of 22 (31.8%) unsorted marrow samples and in 14 of 22(63.6%) CD138(+)-sorted marrow samples. Both of the difference was statistically significant (p = 0.001 and p = 0.035 respectively). Percentages of cytogenetic alterations detected in unsorted bone marrow cells correlated positively with percentage of plasma cells tested by bone marrow smears or flow cytometry. When percentage of plasma cells tested by bone marrow smears exceed 50%, or by flow cytometry exceed 10%, there was no difference between 2 methods. It is concluded that immunomagnetic sorting of CD138(+) cells increases the probability of detection of the 13q14 deletion and 14q32 rearrangement in bone marrow samples. The low detectable rate of genetic aberration in unsorted bone marrow cells is associated to the low percentage of plasma cells in bone marrow samples, higher percentage of plasma cells can partly overcome the shortage of unsorted detection method. When percentage of plasma cells tested by bone marrow smears exceed 50%, or by flow cytometry exceed 10%, there was no difference between 2 methods.

OBJECTIVETo probe into the mechanism and methods of needle knife relaxing therapy for treatment of osteoarthritis of knee from biomechanical view.

METHODSNeedle knife relaxing therapy was given to 92 pain points around the knee joint in 14 cases of osteoarthritis of knee, and the displacement of the local pain point under the stress of 500 g (L500 g) was measured and the VAS scores were recorded before and after treatment.

RESULTSL500 g of the pain point was (4.72+/-1.03) mm before treatment and (5.39+/-1.01) mm after treatment with a very significant difference before and after treatment (P<0.01), and VAS score was (7.10+/-1.49) points before treatment and (1.49+/-1.24) points after treatment with a very significant difference before and after treatment (P<0.01), and there was a linear correlation between the changes of L500 g and VAS scores.

CONCLUSIONThere was close connection between the local pain and tension of local soft tissue in knee osteoarthritis. The needle knife relaxing therapy can relieve the neurovascular compression or traction syndrome by relaxing the local contracted, adhesive soft tissue, so as to relieve tension pain and finally recover internal force equilibrium of the knee joint.

OBJECTIVETo explore the deletion rate, clinical correlation and prognostic significance of 1p21 deletion, a novel genetic prognostic index, in patients with multiple myeloma (MM).

METHODSThe interphase fluorescence in situ hybridization (I-FISH) was performed on purified CD138⁺ plasma cells from 78 newly diagnosed patients from Sep 2007 to Sep 2012 receiving thalidomide-based chemotherapy by using BAC probe covered 1p21.2 region that contains the human cell division cycle 14A (HCDC14A) gene. Deletion rate, the cell percentage of deletion, clinical relevance and prognostic significance were analyzed in myeloma patients.

RESULTSAmong 78 patients, there were 51 males and 27 females, the median age was 59(42-81). The deletion rate of 1p21.2 was 23.1%. Some patients had amplification (amp) of 1p with amp rate of 5.1% in 1p21.2, the amp rate was significantly lower than the deletion rate (P=0.001). 1p21.2 deletion was positively correlated with renal lesion (Cr≥177 μmol/L), high percentage of plasma cells in bone marrow, high LDH (≥220 U/L) and high β2-MG (P=0.014, 0.000, 0.010 and 0.022, respectively). With a median follow-up time of 15.0(1.0-53.5) months, the estimated median progressionfree survival (PFS) and overall survival (OS) time for patients with 1p21 deletion was (12.0±2.7) and (14.0±3.4) months, however those were (30.0±8.0) and (38.5±1.8) months in patients without 1p21 deletion, respectively (P=0.000). On multivariate analysis, which included complex karyotype, LDH≥220 U/L, renal lesion and del(17p13), 1p21 deletion remained as an independent risk factor for PFS (HR: 3.312, 95% CI: 1.095-10.017, P=0.034) and OS (HR: 4.961, 95% CI: 1.487-16.552, P=0.009).

CONCLUSION1p21 deletion is an important genetic prognosis indicator in multiple myeloma patients.

OBJECTIVETo explore the efficacy and prognosis of first-line autologous hematopoietic stem cell transplantation (ASCT) for newly diagnosed patients with multiple myeloma(MM).

METHODSFrom January 2005 to December 31, 2012, 60 patients with MM were enrolled. All patients received thalidomide or/and bortezomib-based induction therapy, then received high-dose melphalan (200 mg/m²) and autologous stem cell support to get a ≥ partial response (PR), and followed by thalidomide-dexamethasone (TD) ±bortezomib as consolidation or maintenance treatment. With the follow up to December 31, 2012, the overall survival (OS), progression free survival (PFS) and the prognostic factors, including ISS stage, response and fluorescent in situ hybridization (FISH) data of cytogenetics were analyzed.

RESULTSWith a median follow up of 36.8 (12.0-102.5) months, the median OS and PFS estimate were not reached and 86.5 months, respectively. After transplantation, all (100%) patients received very good partial response (VGPR), and 34 (56.7%) patients achieved complete response (CR) after consolidation or maintenance treatment. The patients that achieved CR resulted in long term PFS (P=0.030), with no difference in OS (P=0.942). The univariate analysis showed that the abnormalities, including 13q14 deletion, 1q21 gain, IgH location and p53 deletion had the prognostic impacts. If the t(4;14) or p53 deletion was excluded, there would be no correlation between 13q14 deletion or 1q21 gain with PFS and OS. The patients with p53 deletion had a worst survival.

CONCLUSIONThere has been significant improvement in the outcome for young MM patients by using ASCT and novel drugs. Cytogenetic abnormalities and response to therapy are the main factors affecting the survival of patients.
