Much progress has been made in the diagnosis and treatment of Hodgkin's lymphoma, which has become a highly curable malignancy.However, prolonged survival makes clinicians pay more attention to long-term toxicities of treatment.Consequently, individualized treatment based on disease stage and risk factors is a research hotspot at present.This article reviews recent advances in the individualized treatment of early-stage classical Hodgkin's lymphoma.

The degranulation of mast cells represents a pivotal e-vent in the allergic disorders.The Src family kinases(SFKs)are as a starting signal in the activation of mast cell.Lyn,Fyn and Syk play important regulatory role in the degranulation of mast cells.Regulating SFKs can reduce the degranlation process and inhibit the allergic disorders.Therefore,SFKs inhibitors can be potential drugs in the allergy.It is necessary to study the targeted medicine of SFKs,which will be a new direction of drug develop-ment.

Objective To discuss the surgical effect of adult lipomatous tethered cord syndrome (TCS). Methods The clinical data of 29 patients with adult lipomatous TCS were systematically analyzed. Eleven of male and 18 of female,who ranged from 20 to 59 years. All patients were performed filum terminale release and lipoma excision, the clinical outcome after operation was analyzed according to Hoffman grading criteria and visual analog scale (VAS). Results According to Hoffman grading criteria, 9 cases were obviously improved in leg muscle weakness, including 1 case with urination disturbance improved significantly. Also the lower back pain of patients were improved obviously: (2.63 ± 1.30) scores vs. (8.67±0.30) scores, there was significant difference (P<0.05). Conclusions Filum terminale release and lipoma excision can effectively improve the symptom of lower back pain of adult lipomatous TCS patients, meanwhile the symptom of paraparesis can improve appropriate postoperatively. But urinary deficits do not show a significant change.

Objective To determine the relation between the graduation and type of Modic change and low back pain. Methods Ninety-seven patients with low back pain associated with Modic change were enrolled, and the data of clinical were analyzed. The degree of back pain was evaluated by visual analog score (VAS) and Oswestry disability index (ODI). The relation between Modic change and the degree of low back pain was evaluated. Results In 97 patients, the type of Modic change:28 cases (28.9%) were type Ⅰ, 37 cases (38.1%) were type Ⅱ, 11 cases (11.3%) were Ⅱ/Ⅲ, and 21 cases (21.6%) were type Ⅲ. The graduation of Modic change:39 cases (40.2%) were minimal, 34 cases (35.1%) were moderate, and 24 cases (24.7%) were severe. The VAS of type Ⅰ, type Ⅱ, typeⅡ/Ⅲand typeⅢin patients with Modic change were (3.8 ± 0.4), (2.6 ± 0.2), (1.7 ± 0.5) and (1.0 ± 0.6) scores, and there were statistical differences (P<0.05). The ODI scores of type Ⅰ, type Ⅱ, type Ⅱ/Ⅲ and type Ⅲ in patients with Modic change were (11.8 ± 0.7), (8.4 ± 1.1), (5.7 ± 1.3) and (2.0 ± 1.0) scores, and there were statistical differences (P<0.05). Spearman correlation analysis result showed that the type of Modic change was negatively correlated with the intensity of low back pain (r=-0.342, P<0.01). There were no statistical difference in VAS and ODI score among the patients with minimal, moderate and severe of Modic change (P>0.05). Spearman correlation analysis result showed that the graduation of Modic change had no correlation with the intensity of low back pain (r = 0.351, P>0.05). Conclusions The graduation of Modic change does not directly correlate with the low back pain, but the type of Modic lesion is more important.

AIM:Discoid meniscus is named because its width and height are abnormally increased like a disc.In this study,we observed the injury classification and special features of discoid meniscus and natural meniscus,and compare the postoperative outcome of arthroscopy comparatively.METHODS:①360 cases of meniscus injury in knee joint were selected from the First Affiliated Hospital of Anhui Medical University from June 2001 to September 2006.They were divided into natural meniscus injury group(n =300),and discoid lateral meniscus injury(n =60).People with complete clinical data before operation and following data,confirmed by arthroscopy were selected.The written informed consent was obtained from them.②Meniscus injury in 360 cases was examined by arthroscopy,and plasty,or partial excision or incomplete resection or full resection was performed according to the injury types and surgical circumstance.③All subjects were followed for 6 months to 2 years.The knee function was evaluated by the criteria of Ikeuchi.RESULTS:300 cases of natural meniscus injury and 60 of discoid lateral meniscus injury were all included in the result analysis.①Five tear types of natural meniscus were as follows:43.7% longitudinal,30% radial,12.3% horizontal,7.5% transverse,and 6.5% complex.Four tear types of discoid meniscus were as follows:68.3% horizontal,6.7% radial,3.3% longitudinal,and 21.7% complex tear.②The surgical pattern was determined by the injury types,and all patients were followed up.In 300 cases of natural meniscus,there were 62 knees with excellent function,190 with good,34 with fair and 14 with poor.The excellent and good rate was 85%.In 60 cases of discoid meniscus,there were 19 knees with excellent function,34 with good,5 with fair and 2 with poor.The excellent and good rate was 90% approximately.CONCLUSION:Discoid meniscus is different in anatomical feature and histological structure from natural meniscus;therefore the arthroscopic surgery for discoid meniscus is also different.

Results All of cases were removed and diagnosed successfully, including 7cases of early invasive ductus cancer and 1 case of ductal carcinoma in situ. Conclusion The method of staining with the mixture of methylene blue and meglucamine diatrizoate could significantly improve the accuracy of removal of minute mammary lesion and the percentage of diagnois of early breast cancer, and have high safety.

BACKGROUND:Tranexamic acid is a synthetic anti-fibrinolytic drug, and can effectively control blood loss after total knee arthroplasty through vein. OBJECTIVE:To evaluate the effectiveness and safety of tranexamic acid in reducing blood loss after primary unilateral total knee arthroplasty. METHODS:From 2014 to 2015, 100 patients from the Department of Lower Limb, Sichuan Orthopaedic Hospital underwent primary unilateral total knee arthroplasty, and randomly divided into test group which used tranexamic acid and control group which used tranexamic acid, with 50 cases in each group. 1 g tranexamic acid was infused into the vein at 10 minutes before total knee arthroplasty in the test group, but tranexamic acid was not given in the control group. RESULTS AND CONCLUSION:The amount of total blood loss, postoperative wound drainage in 24 hours, and the amount of blood transfusion were significantly less in the test group than in the control group (P < 0.05). No significant differences in intraoperative blood loss and the number of patients receiving blood transfusion were found between the test and control groups. No significant difference in preoperative hemoglobin levels was detected before surgery, but hemoglobin levels were decreased after surgery between the two groups. Postoperative hemoglobin levels were apparently higher in the test group than in the control group after surgery. At 24 hours after surgery, no significant difference in coagulation was detectable between the two groups. At 6 days, double lower limb vein color Doppler ultrasound examination did not reveal deep vein thrombosis in both groups. These findings verify that treatment with tranexamic acid in the vein before primary unilateral total knee arthroplasty can evidently diminish the amount of perioperative blood loss and blood transfusion, reduce the risk and cost of blood transfusion, which is good for rehabilitation and does not increase the risk of deep vein thrombosis.

Through comparative study on Naotaifang containing serum and plasma proteomics (peptide), this article revealed differential proteins (peptides) in the Naotaifang. The characteristics of differential proteins were identified with mass spectrometry. It provides scientific evidences for the pharmacodynamic material basis and Chinese herbal medicine plasma pharmacological method development in the exploration of Naotaifang. A total of 20 healthy adult SD rats were randomly divided into the control group, Naotaifang treatment group according to their weights. Ten rats in each group. Intragastric administration of medication was given for seven consecutive days. Before surgery, rats were fed with water but without food. One hour after the last drug administration, 10% chloral hydrate was injected for intraperitoneal anesthesia. Blood was taken through the common carotid artery. Serum and plasma samples were made after blood was taken from each rat. Serum and plasma samples of five rats were randomly selected from each group. And the two-dimensional electrophoresis (2-DE) technique was used in the comparative study of serum pro-teomics (peptide). The 300 DPI scanning and PDQuest 7.3.0 were used in the analysis. The ESI-MS/MS was used to identify important differences in proteins and screen characteristic serum and plasma protein. The results showed that 20 differential proteins of 5 plasma samples were identified. There were 15 types of proteins expressing up-regulation and 5 types expressing down-regulation. Comparative analysis on the 2-DE gel pictures of Naotaifang containing serum, 19 differential proteins of 5 plasma samples were identified, among which 15 types of proteins express up-regulation and 4 down-regulation. Comparative analysis on the 2-DE gel pictures of Naotaifang containing serum and Naotaifang containing plasma showed that 24 differential proteins of 5 plasma samples were identified, among which 9 types of proteins express up-regulation and 15 down-regulation. The highly expressed proteins were selected to MALDI-TOF-MS between Naotaifang containing serum and Naotaifang containing plasma. There were six successful-ly identified proteins, which were inter-alpha trypsin inhibitor, heavy chain 3, group-specific component, comple-ment factor B, Receptor Complexed with A Heterodimeric Fc, isoform CRA-d, Transferrin. It was concluded that protein with obvious changes in the Naotaifang containing serum and plasma may be related with fibrinolysis and an-ticoagulant. These proteins are involved in angiogenesis, inflammation and other pathological regulations of physiolog-ical processes. They are of great significance in the study of effective target and its signal transduction pathway of Naotaifang.

Atherosclerosis is a complex metabolic cardiovascular disease. such inflammatory phenomena as the invasion of lipid into the arterial intima and accumulation, the increase of foam cells, the exacerbation of inflammatory lesions, plaque necrosis and disintegration, ulcer bleeding and thrombosis, fibrosis and calcification, etc, are basic pathological characteristics of ather-osclerosis. In this process, macrophages and T lymphocytes play an important role. In recent years,atherosclerosis pathology re-search mainly focuses on the role of macrophage polarization.
Basically,macrophage can be divided into two subtypes: classi-cal activation macrophage M1 and alternative activation macro-phage M2. Therefore to paper reviews the meaning of M1 and M2 macrophage polarization during atherosclerosis, regulatory pathways and drug targets research status to provide new direc-tion for innovative drugs and disease treatment.

Objective To compare the effects of peripatellar peripheral nerve partially and totally depolarized in total knee arthroplasty (TKA). Methods 66 TKA patients were divided into partially depolarized group (A, 42 knees) and totally depolarized group (B, 38 knees). The scores of knee-joint, Feller and Visual Analogue Scale were recorded. Results There was no significant difference in all the scores between 2 groups before operation (P>0.05). All the scores improved after operation (P<0.05), however, there was still no significant difference between 2 groups (P>0.05). Conclusion Patellar peripheral nerve partially depolarization technique can reduce postoperative knee pain, which has the same effect with totally depolarization.
