BACKGROUND:The purpose of the treatment of lumbar spondylolisthesis is to reconstruct the spine sequence and vertebral stability, relieve nerve compression, and achieve permanent lumbar fusion.
OBJECTIVE:To explore the restore of vertebral stability of the lumbar spondylolisthesis patients after lumbar fusion and implant internal fixation.
METHODS:The lumbar spondylolisthesis was often divided into dysplastic, isthmic, degenerative, traumatic and pathological with Wiltse classification. The slip degree of upper vertebra relative to lower vertebra on the lumbar X-ray film was divided into five grades, and then the appropriate treatment method was selected according to the classification, grading and specific circumstances of the lumbar spondylolisthesis patients.
RESUTLS AND CONCLUSION:The strong fusion and internal fixation and the rigid connection between
implants and vertebra are often used to stabilize the spine and correct deformities with high bone fusion rate, thus reducing pseudoarticulation formation. Dynamic fusion and internal fixation can distribute the load conduction of rigid internal fixation with elastic material or micro-devices, thus reducing stress shielding and adjacent segment stress concentration. Dynamic non-fusion and internal fixation can change the load transfer mode of spinal
motion segment, inhibit spinal movement and prevent adjacent segment degeneration, in order to make the instable lumbar spine reach its normal activity characteristics, and achieve dynamic reconstruction of lumbar sequence. Lumbar isthmus defects directly repaired with graft is suitable for the young adult with the
symptoms of lumbar spondylolisthesis and without degenerative disc disease. There is no consistent option on which materials and position is suitable for graft in the lumbar spondylolisthesis patients, as wel as which methods for fusion and implant internal fixation can achieve ideal effect.

Objective To investigate the effect of Kang' ai injection and Shenqifuzheng injection on liver function of patients with advanced primary liver cancer after being performed transcatheter arterial chemomembolization (TACE).Methods 120 patients with advanced primary liver cancer were randomly divided into three groups:a control group,a Kang'ai injection group,and a Shenqifuzheng injection group,with 40 patients in each group.All three groups were treated with TACE,and after TACE the control group was treated with anti-infection,inhibiting-acid,protecting-liver function and Shuganning tablets,20 ml/day.On this basis,the Kang'ai injection group was additionally injected with Kang'ai injection,40ml/day,and Shenqifuzheng injection group was additionally injected with Shenqifuzheng injection,250ml/day.All three groups were treated for 15 days.Liver function was tested and compared at the 3rd day,the 7th day and 14th day after TACE in all three groups.Results At the 14th day after TACE,ALT,AST,TBiL,and TBA of the Kang' ai group and Senqifuzheng group [(40.35 ± 10.10) μmol/L、(37.52 ± 10.57) μmol/L、(40.13 ± 8.36) μmol/L、(45.19 ± 19.65) μmol/L in Senqifuzheng group; (40.11 ±7.31) μmol/L,(34.99±9.38) μmol/L,(32.15±6.58) μmol/L,(40.75 ± 6.79) μmol/L in Kang'ai group] were greatly improved than the control group [(61.28 ± 13.38) μmol/L,(57.53 ± 13.36) μmol/L,(68.69± 7.25) μmol/L,(67.75 ± 17.88) μmol/L],with statistical significance (P＜ 0.01).Conclusion Kang'ai injiection and Shenqifuzhcng injection both can reduce liver function damage caused by TACE,thus they can be used together with TACE for treating advanced primary liver cancer.

BACKGROUND:After articular cartilage injury, the injured cartilage almost has no self-healing ability. Articular cartilage injury repair has been always a difficulty in clinical work.
OBJECTIVE:To explore the types and biological characteristics of stem cels for articular cartilage repair and to ensure the role and relative merits of stem cel transplantation in articular cartilage repair.
METHODS:PubMed and CNKI were retrieved by the first author for relevant articles published from 1998 to 2015 using the keywords of “articular cartilage injury, mesenchymal stem cels, regeneration” in English and Chinese, respectively. Finaly, 47 articles were included in result analysis.
RESULTS AND CONCLUSION: Stem cel therapy is the most effective method for repair of articular cartilage injury. Mesenchymal stem cels from bone marrow, adipose and umbilical cord have strong chondrogenic and cloning capacities. Bone marrow mesenchymal stem cels have a stronger differentiation potential, and can be used for repair of cartilage injury. Umbilical cord-derived mesenchymal stem cels have a low tumorigenicity. Adipose-derived stem cels can proliferate and grow faster. Stem cels combined with natural carrier materials, such as colagen, gelatin, fibrin and alginate, can promote cel adhesion, differentiation and proliferation, in order to build an effective tissue engineered cartilage for repair of articular cartilage defects.

Pregnancy and the puerperium have been recognized to increase the risk of stroke, particularly from late pregnancy and through the puerperium. The reported incidences of stroke during pregnancy and the puerperium varied widely, but when it occurs, there may be implications for management of the patient and delivery of the child. Important causes of stroke during pregnancy and the puerperium include preeclampsia and eclampsia, cardioembolism, rapture of cerebral vascular anomaly, cerebral aneurysm rupture and antiphospholipid syndrome, thrombotic thrombocytopenic purpura. Management of patients with pregnancy-related stroke is largely the same as that of nonpregnant patients, including thrombolysis, atntiplatelets and anticoagulants, with more consideration on maternal and fetal risks.

Objective: To investigate the clinical effect of total cystectomy and W-shaped orthotopic ileal neobladder for bladder cancer. Methods: Total cystectomy and W-shaped orthotopic ileal neobladder were performed on 29 male patients and 3 female patients. Atfer the cystectomy, 35-40 cm terminal ileal segment was isolated to make W-shaped orthotopic ileal neobladder. Bilateral uretero-ileal anastomoses were constructed by nipple technique, urethral stump was sutured to the lowest portion of the ileal pouch. Results: All surgeries were completed successfully. Patients were able to void by increasing the abdominal pressure, daytime continence rate was 87.5% and nighttime continence rate was 78.1%. The mean neobladder capacity was 410.6 mL and the mean postvoid residual urine was22.7 mL at 6 months. After the surgery, ileal neobladder leakage occurred in 3 (9.4%) patients, mild ileus occurred in 2 (6.3%) patients, ileo-urethral anastomosis stricture developed in 1(3.1%) patient, and dysuria occurred in 3 (9.4%) patients because of the mucus.HTe complications were treated properly and satisfactory results were obtained. Erection was preserved in 5 of the 9 male patients with normal erectile function, and normal sexual function was preserved in 1 female patient who underwent uterus-sparing cystectomy. HTe mean follow-up was 15 months.One patient died of distant metastasis and pneumonia, while other patients survived without tumor. Conclusion: Total cystectomy and W-shaped orthotopic ileal neobladder have the advantages of voiding through the native urethra, satisfactory continence, low complication rates of upper urinary tract damage and electrolyte imbalance. W-shaped orthotopic ileal neobladder may be considered as the ifrst option of urinary diversion atfer cystectomy. Postoperative management should focus on complications and follow-up.

AIM To explore the effect of breviscapine on primary cultural calf pulmonary artery smooth muscle cell (PASMC) proliferation. METHODS By primary cuture of calf PASMC, the effect of PASMC proliferation was analysed using MTT colorimetry, flow cytomerty, Giemsa staining. RESULTS Compared with control group, PASMC proliferations in breviscapine group was significantly inhibited from G 0/G 1 to S phases in the cell cycle. CONCLUSION Breviscapine could significantly inhibit PASMC profiferation. The mechanism for this may due to inhibition of protein kinase C.

Objective To investigate the effect of Chinese medicine Louxie mixture on vascular reactivity in atherosclerosis rats. Methods Forty male rats were randomly divided into four groups: the control group (A group, n＝10) was fed with normal diet; the model group (B group, n＝10), atorvastatin treated group (C group, n＝10 and Louxie mixture group (D group, n＝10) were fed with high fat/cholesterol diet. Atorvastatin 10 mg/kg·d-1 was administered to C group and Louxie mixture to D group for 10 weeks by gavages. Serum endothelin-1 (ET-1), nitric oxide (NO) and nitric oxide syntheses (NOS) were observed in different groups before and after the treatment. Vascular reactivity of aortic rings was measured by both the sodium nitroprusside(SNP)-induced endothelium-independent relaxation (NEDR) and the acetylcholine (Ach)-induced endothelium-dependent relaxation (EDR) in different groups. Results After treatment, the (19.03±1.72)μmol/l; NOS (24.78±0.25)U/ml vs (15.36±0.24U/ml), P＜0.01], while the level of ET-1in B levels of NO and NOS in B group were significantly lower than those in A group [NO(35.73±3.72)μmol/l vs group was higher than that in A group [(34.58±4.00) pg/ml vs (117.58±5.34)pg/ml,P＜0.01]. The levels of NO and NOS were significantly increased and the level of ET-1 was decreased in C and D groups after the treatment [NO(C: 31.30±1.96 umol/l;D: 32.85±3.70 umol/l); NOS (C: 21.96±1.07 U/ml ; D: 19.78± 1.20U/ml ); ET (C:58.26±5.14 pg/ml; D:59.30±5.73 pg/ml), P＜0.01]. The activities of NEDR were similar in four groups[SNP Emax (A: 97.33±1.31; B: 98.24±1.04;C: 97.52±1.09; D: 97.91±1.59)%, P＞0.05], but the level of EDR in the B group (P＜0.01) was the lowest among four groups [Ach Emax (A: 72.65±3.31; B: 32.68±2.39;C: 61.63±2.07; D: 57.58±2.43)%, P＜0.01]. Conclusion Chinese medicine Louxie mixture can protect vascular function in atherosclerosis rats.

Objective To investigate the effects of dynamic standing bed training on the functional recovery of hemiplegic patients. Methods Sixty hemiplegic patients with Barthel index score of 40 were randomized into a standing rehabilitation group and a control group. The patients in standing rehabilitation group were asked to take part in dynamic standing bed training in addition to drug treatment. Those in the control group were treated with medication only. After 1 to 2 weeks of treatment, the weight-bearing ability of the lower limbs, balance, muscle tone, trunk control and the cardiovascular response were evaluated and compared with those before the treatment. Results The scores of weight-bearing, balance, muscle tone and trunk control of the patients in the standing rehabilitation group were better improved than those in the control group. The changes of blood pressure and pulse of patients were reduced and within the range of safety after 2 weeks of training. Conclusion Dynamic standing bed training is beneficial for the functional recovery of hemiplegic patients. It is safe for the patients in terms of cardiovascular response.
