Comparison of clinical effects of different anterior surgical methods for the treatment of single segment cervical disc herniation / 中国骨伤

OBJECTIVE@#To compare the clinical effects of different anterior surgical methods in treating single segment cervical disc herniation.@*METHODS@#The clinical data of 46 patients with single-segment cervical disc herniation underwent surgical treatment from September 2013 to September 2018 were retrospectively analyzed. The patients were divided into three groups according to different surgical methods. Among them, 23 patients in the anterior percutanousendomic cervical dissection (APECD) group, there were 8 males and 15 females, aged (47±3) years old, prominent segments were C@*RESULTS@#All 46 patients were followed up for 12 to 24 (17.57±3.15)months. The follow-up time of APECD, CDR, ACDF groups were (17.30±3.25), (17.80±3.16), (17.85±2.88) months, and operation time were (95.48 ±13.85), (58.50±7.09), (76.00±15.72) min, respectively, there were no significant differences in follow-up time and operation time between two groups(@*CONCLUSION@#The three anterior surgical approaches can achieve satisfactory clinical results for the treatment of single-segment cervical disc herniation. However, the improvement rate of the CDR group and the activity of the retained responsibility segment are better than those of the other two groups. APECD surgery may have recurrence.

Efficacy evaluation of modified lamina osteotomy replantation versus traditional lamina osteotomy replantation in treating lumbar disc herniation with lumbar instability / 中国骨伤

<p><b>OBJECTIVE</b>To evaluate the clinical effects of modified lamina osteotomy replantation versus traditional lamina osteotomy replantation in the treatment of lumbar disc herniation with lumbar instability.</p><p><b>METHODS</b>The clinical data of 146 patients with unilateral lumbar disc herniation with lumbar instability underwent surgical treatment from March 2008 to March 2013 were retrospectively analyzed. Patients were divided into two groups according to osteotomy replantation pattern. There were 77 patients in the traditional group (underwent traditional lamina osteotomy replantation), including 42 males and 35 females with an average age of (49.4±18.5) years;the lesions occurred on L₄,₅ in 46 cases, on L₅5S₁ in 31 cases. There were 69 patients in modified group (underwent modified lamina osteotomy replantation), including 37 males and 32 females with an average age of (49.8±17.9) years;the lesions occurred on L₄,₅ in 40 cases, on L₅S₁ in 29 cases. The operation time, intraoperative blood loss, complication rate during operation, lamina healing rate, recurrence rate of low back and leg pain were compared between two groups. Visual analogue scales (VAS) and Japanese Orthopadic Association (JOA) scores were used to evaluate the clinical effects.</p><p><b>RESULTS</b>The operation time and intraoperative blood loss were similar between two group (>0.05). There was significantly different in nerve injury rate(5.80% vs 16.9%) and dural injury rate(1.45% vs 9.09%) between modified group and traditional group(<0.05). The recurrent rate of low back pain of modified group was higher (91.30%, 63/69) than that of traditional group (76.62%, 59/77), and the intervertebral fusion rate of modified group was lower(8.70%, 6/69) than that of traditional group (29.9%, 23/77) at 3 years after operation. Postoperative VAS scores of all patients were significantly decreased at 6 months, 1, 2, 3 years, and JOA scores were obviously increased (<0.05). At 1, 2, 3 years after operation, VAS scores of modified group were significantly lower than that of traditional group(<0.05), and JOA scores of modified group were higher than that of traditional group(<0.05).</p><p><b>CONCLUSIONS</b>Modified lamina osteotomy replantation has better long-term efficacy(in the aspect of recurrent rate of low back pain, intervertebral fusion rate, VAS and JOA score at three years follow-up) in treating lumbar disc herniation with instability.</p>

Serum and glucocorticoid inducible protein kinases (SGKs): a potential target for cancer intervention

The serum and glucocorticoid inducible protein kinase (SGK) family members share similar structure, substrate specificity and function with AKT and signal downstream of the phosphatidylinositol 3-kinase (PI3K) signalling pathway. They regulate a range of fundamental cellular processes such as cell proliferation and survival, thereby playing an important role in cancer development. This perspective intends to give an overview on the involvement of SGKs (particularly SGK3) in cancer progression, and compares the actions of SGK3 and AKT in cell cycle regulation, oncogenic signalling, and the potential as a therapeutic target for cancer.

Treatment and prognostic analysis of 1638 patients with non-small cell lung cancer / 中华外科杂志

<p><b>OBJECTIVE</b>To study the prognosis and prognostic factors of non-small-cell lung carcinoma (NSCLC) according the new TNM stage system.</p><p><b>METHODS</b>Clinic data of 1638 inpatient cases admitted from January 2001 to January 2005 were retrospectively reviewed. There were 1083 male and 555 female patients in the study and the average age was 59.5 years. All the patients received surgical procedures.</p><p><b>RESULTS</b>The overall 1, 3, 5-year survival rate was 80.0%, 52.3%, 39.0%. The main prognostic factors were bronchial stump, operation type, T stage, N stage, the number of lymph nodes (LNs) in lymph nodes dissection (1 - 10, 11 - 20, and > 20), overall N stations (< 4 and ≥ 4) and postoperative radiotherapy (all P < 0.05). Cox regression suggested that T stage (P = 0.000), N stage (P = 0.000), operation type (P = 0.001) and LNs (P = 0.013) were independent factors affecting the prognosis.</p><p><b>CONCLUSIONS</b>The overall survival rate of NSCLC is poor.

Changes of activated circulating endothelial cells and survivin in patients with non-small cell lung cancer after antiangiogenesis therapy / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Although antiangiogenesis therapy plays an important role in anti-neoplastic treatment with its recognized efficacy and slight adverse effect, there is no prospective clinical trial to define ideal markers for predicting efficacy of antiangiogenic therapy. This study was undertaken to investigate the changes of activated circulating endothelial cells (aCECs) and survivin after anti-angiogenesis therapy and their significance in predicting the efficacy of the therapy.</p><p><b>METHODS</b>Patients of non-small cell lung cancer (NSCLC) treated with chemotherapy with or without Endostar were observed. The amount of activated CECs was detected by flow cytometry, and the expression of survivin mRNA was determined by real-time polymerase chain reaction (PCR).</p><p><b>RESULTS</b>After treatment, the amount of activated CECs decreased significantly in clinical benefit cases (P = 0.021 in chemotherapy alone, P = 0.001 in chemotherapy plus Endostar), increased in disease progressive cases (P = 0.015 in chemotherapy alone, but P = 0.293 in chemotherapy with Endotatar). After therapy, the expression of survivin mRNA decreased in clinical benefit cases (P = 0.001) and increased in disease progressive cases (P = 0.018). A positive correlation was found between activated CECs and survivin in the chemotherapy group pre- and post-therapy (P = 0.001 and 0.021, respectively), but only in the chemotherapy with Endostar group pre-therapy (P = 0.030) rather than post-therapy. A positive correlation was found between the decreased activated CECs after therapy and time to progression (TTP) (r = 0.322, P = 0.012); a negative correlation was found between the amount of survivin mRNA in serum post-therapy and TTP (r = -0.291, P = 0.048).</p><p><b>CONCLUSIONS</b>Activated CECs and survivin may be ideal markers forecasting efficacy and prognosis of NSCLC. The former can reflect more sensitively antiangiogenic efficacy and the latter is more sensitive to shrinkage or swelling of tumors. Their combination can evaluate more accurately the efficacy of antiangiogenic therapy of NSCLC.</p>
