Objective To review and analyze the clinical effect of combined posterior mini-invasive fixation with anterior debridement via small incision for the treatment of single segment lumbar vertebral tuberculosis. Methods Totally 31 cases with single segment lumbar tuberculosis (both borderline tuberculosis) without attachment involvement underwent one-stage anterior debridement, interbody fusion and posterior mini-invasive fixation from July 2010 to July 2015. Among these patients, 19 were male and 12 were female. The average age was (36.1±17.8) years old (ranged 21-61 years old). The average course of disease was 11(9, 12) months (ranged from 2 to 16 months). All were single segment involvement, and the involved segment was L2-3 in 7 cases, L3-4 in 10 cases, L4-5 in 6 cases, and L5-S1 in 8 cases. The clinical manifestations included lumbar back pain in 31 cases with an average pain visual analog score (VAS) of 7(6, 8) points. ASIA grade of spinal cord injury was E in 25 cases and D in 6 cases. Paravertebral abscess occurred in 22 cases and iliac fossa gravity abscess appeared in 9 cases. Kyphosis was observed in 12 cases and the average Cobb angle was 21° ± 6° . Quadruple anti-tuberculosis chemotherapy was used for at least 2 weeks preoperatively. Posterior mini-invasive fixation was fulfilled on prone position, including mini-invasive percutaneous screws in 18 cases and pedicle screw fixation via Wiltse approach in 13 cases. Posterior distraction and deformity correction were performed simultaneously for patients with kyphosis. Then the patients were changed to lateral position for anterior debridement, bone grafting and/or titanium mesh fusion. Results The average operation time was (204±54) min (ranged 160-240 min) in 31 patients, and the mean blood loss was (168±73) mL (ranged 100-300 mL). Delayed healing of anterior incision occurred in 1 case and the incision healed after two-week dressing of wound. The incision healed well in the rest 30 cases. No complications such as nerve function, blood vessel injury were found in patients. The VAS scores of the 3 days after operation were 1.3 ± 0.3 and 2.1 ± 1.4 in percutaneous group and Wiltse approach group, respectively, and the difference between them was statistically significant ( P<0.05). The VAS score of low back pain was 2(1, 3) points in all the 31 patients three months after operation, which was significantly lower than that before surgery (P<0.05). The six patients with neurological symptoms recovered to E grade after operation. The average Cobb angle correction was 15°±5° in 12 patients with kyphosis (P<0.05), which was significantly decreased compared with that before surgery (P<0.05). All patients were followed up for an average of (36.8 ± 9.3) months (ranged from 12 to 72 months). The clinical healing of tuberculosis was achieved at the final follow-up in all the 31 patients. No complications were observed, such as lumbar kyphosis, internal fixation loosening and breakage, dislocation and titanium mesh subsidence. Conclusion Mini-invasive posterior internal fixation and anterior debridement via small incision is effective for the treatment of single segment lumbar vertebral tuberculosis in lesion debridement and spine stability reconstruction by short segment fixation. This technique can reduce fused segments, surgical trauma of anterior approach and related complications.

Objective:To investigate whether the omental-adipose stromal cells (O-ASCs) exposing to gastric cancer-conditioned medi-um (CM) could be inducted to differentiate into carcinoma-associated fibroblasts (CAFs) and the effect of ERK signaling pathway in the process. Methods: We identified O-ASCs by examining their ability to differentiate osteogenic and adipogenic lineages and through flow cytometry. O-ASCs were co-cultured with MGC803 and SGC7901CM. The expression of CAFs markers (α-SMA, FSP-1, and vimentin) and paracrine factors (VEGFA, TGF-β1, FAP, and SDF-1) were evaluated by RT-PCR and Western blot. In vitro cultures of O-ASCs were divided into three groups:the control, SGC7901-CM, and SGC7901-CM+U0126 groups. Cells were collected after 12 h. West-ern blot was performed to evaluate the expression ofα-SMA, FSP-1, ERK, and p-ERK1/2. Results:The primary cells were O-ASCs. The expression levels of CAFs markers (α-SMA, FSP-1, and vimentin) and O-ASC paracrine factors (VEGFA, TGF-β1, FAP, and SDF-1) clearly in-creased (P<0.05). In comparison with the control, the expression of ERK in SGC7901-CM group did not change (P>0.05), while the ex-pression of p-ERK1/2,α-SMA, and FSP-1 significantly improved (P<0.05). Comparison of SGC 7901-CM+U0126 and SGC 7901-CM groups showed that the expression levels of ERK had no statistical difference (P>0.05), while the expression levels of p-ERK1/2,α-SMA, and FSP-1 decreased (P<0.05). Conclusion:O-ASCs participate in the peritoneal metastasis of gastric cancer through differentiation by CAF and paracrine factors. The ERK signaling pathway is important in the differentiation of O-ASCs towards CAFs.

Objective To observe the effects of electroacupuncture (EA) on c-Jun amino terminal kinase (JNK) signaling pathway and inflammatory cytokines interferon-γ (IFN-γ) in substantia nigra (SN) cells of rotenone-induced rats model of Parkinson's disease (PD),and explore the underlying mechanism of EA on PD.Methods A total of 32 male Sprague-Dawley mice were randomly and evenly divided into a normal group,a shamoperation group,a model group and an EA group.Model group and EA group were injected intradermally with rotenone (1 mg/kg,dissolved in DMSO and saline,concentration:O.25 mg/ml) on the nape of neck.Sham-operation group was injected the same dose of DMSO and saline.Normal group had no intervention.EA group was applied to Fengfu (DU16) and Taichong (LR3) acupoints after the establishment of PD model in rats.Behavioral assessment was conducted after the treatments,the rats were sacrificed for sampling substantia nigra tissue to detect the expressions of tyrosine hydroxylase (TH),p-c-Jun amino terminal kinase (p-c-Jun) and interferon-γ(IFN-γ) protein with Western blotting (WB).Results Model rats showed significant PD syndrome characteristics,comparing with normal group and sham group,the difference was not statistically significant (P ＞ 0.05).The results of open box test showed that the scores of model group rats decreased significantly in terms of the horizontal movement [(19.12 ±2.34) points] and vertical locomotor activity [(5.27 ± 1.04) points] when compared with normal group and sham group,the difference was statistically significant (P ＜ 0.05).After EA treatment,locomotor activity of rats increased significantly when compared with model group (P ＜ 0.05),however,the normal group and sham group was not statistically and significantly different in locomotor activity (P ＞ 0.05).Compared with normal group,the expression of TH protein in (0.183 ± 0.0213) reduced significantly and the expressions of p-c-Jun (0.388 ± 0.0283) and IFN-γ protein(0.453 ± 0.0332) increased significantly in model group,the difference was statistically significant (P ＜0.05).Compared with normal group,the expression of TH protein(0.324 ± 0.0538) reduced and the expressions of p-c-Jun(0.207 ± 0.0592) and IFN-γ protein (0.239 ± 0.0215) increased in EA group,the difference was not statistically significant (P ＞ 0.05).Compared with model group,the expression of TH protein increased significantly in EA group(P ＜ 0.05),the expressions of p-c-Jun and IFN-γ protein reduced significantly in EA group(P ＜ 0.05).Conclusion EA therapy may reduce the expression of IFN-γ protein in SN of PD rats model by regulating the expression of JNK/mitogen-activated protein kinase (MAPK) pathway,which may delay the process of PD.
