A radiological study between anterior and posterior surgery in patients with basilar invagination and atlantoaxial dislocation / 中华骨科杂志

Objective:To analyze the improvement of patients with basilar invagination and atlantoaxial dislocation that treated by anterior or posterior surgery.Methods:50 patients with basilar invagination and atlantoaxial dislocation that underwent simple anterior or posterior surgery from 2009 to 2021 were included. There were 34 females and 16 males with a mean age of 45.04 years (range, 18-65 years). All patients underwent thin- slice CT scan of the neck. Preoperative and postoperative measurements of atlantoaxial joint distance, atlantoaxial joint angle, atlantoaxial joint displacement, Claus' Height, atlas-dens interval, space available for the cord, cervicomedullary angle, C 0-C 2 angle, and C 2-C 7 angle were measured. Then, the data were analyzed by independent sample t test. Results:25 patients (7 males, 18 females) were included in the anterior surgery group, and 25 patients (9 males, 16 females) were included in the posterior surgery group. The mean age of the two groups was 45.24±9.86 years and 44.72±14.06 years, respectively, showing no statistical difference. The mean last follow-up time of the anterior and posterior surgery group was 6.48±3.14 months and 7.04±2.87 months, respectively. The odontoid distance, atlas-dens interval, space available for the cord and cervicomedullary angle in 2 groups were significantly improved after surgery ( P<0.05), while there were no significant differences in the above parameters between 2 groups ( P>0.05). In the anterior surgery group, the distance and angle of atlantoaxial joint were increased, and the atlantoaxial joint displacement decreased significantly. While in the posterior surgery group, only the atlantoaxial joint space increased ( P<0.05). The C 0-C 2 angle was significantly increased and the C 2-C 7 angle was significantly decreased in the anterior surgery group ( P<0.05), but there was no significant difference in these parameters in the posterior surgery group ( P>0.05). In addition, there was no significant difference in parameters between the two groups at the last follow-up compared with those immediately after surgery. Conclusion:Both anterior and posterior surgery can improve the compression of the spinal cord in patients with basilar invagination and atlantoaxial dislocation. Anterior surgery may be more adequate for the extension and reduction of the atlantoaxial joint space, however, excessive enlargement of the lordosis angle in upper cervical may lead to the reduction of the lordosis in lower cervical.

A clival-cervical plate fixation for the craniovertebral instability: a biomechanical study / 中华骨科杂志

Objective:To develop a specialized clival-cervical plate fixation (CCPF) for anterior surgery to treat craniovertebral instability, and to compare it with a posterior occipitocervical fixation (POCF) in biomechanical validation.Methods:Based on the measurement of 40 adult dry bones and 30 volunteers CT images, the clival-cervical plate was designed and manufactured. 8 cadaveric specimens (occiput-C 3) were tested in five conditions including the intact status, the intact+CCPF status, the injury status, the injury+CCPF status, and the injury+POCF status. Specimens were applied a pure moment of 1.5 N·m in flexion, extension, lateral bending, and axial rotation. Calculating and comparing the range of motion (ROM) and neutral zone (NZ) for the occiput to C 2. The effects of different fixation methods on the distribution of ROMs at the occipitocervical region were compared. Results:The injury+CCPF status constrained ROMs to 1.7° in flexion ( q=4.68, P=0.055) , 1.2° in extension ( q=0.39, P=0.9922) , 2.8° in lateral bending ( q=1.25, P=0.814) , and 4.3° in axial rotation ( q=5.08, P=0.035) , resulted in larger ROM in axial rotation but similar ROMs in other directions ( P>0.05) when compared with the injury+POCF status. There were no significant differences between the above two fixation methods in flexion-extension ( q=1.94, P=0.554) , lateral bending ( q=1.79, P=0.611) and axial rotation ( q=2.14, P=0.478) for the NZs. For the flexion, extension,lateral bendingand axial rotation direction, the proportion of the C 1, 2 ROM to the overall ROM was 28%, 25%, 34% and 56% respectively in the injury+CCPF status, and it was 59%, 53%, 42% and 71% respectively in the injury+POCF status. Conclusion:CCPF is a biomechanically effective alternative or supplemental method of POCF for the craniocervical instability.

Clinicopathology and prognosis of alpha fetoprotein-producing gastric carcinoma / 中华普通外科杂志

Objective:To analyze the clinicopathological features and prognostic factors of alpha‐fetoprotein‐producing gastric carcinoma (AFPGC).Methods:A retrospective analysis was made on 2 671 GC patients admitted from Jan 1998 to Dec 2018 , AFPGC patients and matching AFP negative GC cases were enrolled and their clinicopathological features and prognostic factors were analyzed. The survival curve was drawn by Kaplan-Meier method. Log-rank test was used to test the significance, Univariate analysis was performed by using COX proportional hazard model.Results:There were 98 AFPGC in this study accounting for 4.5% of all GC of the corresponding time period. The proportion of male to female was 2.16∶1, the average age was (65±12) years. The serum AFP levels significantly decreased after operation in most patients (median: 52 ng/ml vs. 5 ng/ml, Ｚ=-2.736, P=0.001). Serum AFP and CEA levels in patients with AFPGC before treatment were significantly higher than that in patients with AFP negative GC (both P<0.05) . Vascular invasion(62.71% vs. 40.68%) and liver metastasis (31.63% vs .6.12%) were more likely to occur in AFPGC groups (both P<0.05). However, there was no significant difference between the two groups in tumor size, location, differentiation and lymph node metastasis (all P>0.05). The prognosis of AFPGC was significant pooer than that in AFP negative GC ( P<0.05). Prognosis of AFPGC patients was significantly correlated with preoperative serum AFP level, TNM stage, lymph node metastasis, simultaneous liver metastasis and vascular invasion (all P<0.05) . COX multivariate survival analysis found that preoperative serum AFP level was independent risk factors of patients with AFPGC ( P<0.05). Conclusion:AFPGC is a special GC charactering poor prognosis .

A study on the correlation between imagingtopographic anatomy and anastomotic leakage after anterior resection for rectal cancer / 中华普通外科杂志

Objective:To study the relation ship between the branch patterns of inferior mesenteric artery (IMA) and imaging pelvic measurement parameters for anastomotic leakage (AL) after anterior resection (AR) of rectal cancer.Methods:Five hundred thirty-four patient were enrolled from Jan 2008 to Dec 2018 at the General Surgery Department of Guizhou Provincial People's Hospital. The AL related imaging risk factors were analyzed by chi-square test or Fisher's exact test.Results:AL was found in 36 (6.7%) patients. AL related mortality rate was 11.1% (4/36) compared to 0.4% (2/498) in those without the complications of no AL cases ( P<0.001). Seven pelvic imaging measurement results were attained in 412 patients including anteroposterior diameter of the inlet of the pelvis, anteroposterior diameter of the outlet of the pelvis, upper edge of the symphysis pubis to the tip of the coccyx, sacrococcygeal distance angle from the lower edge of the pubis to the upper edge of the pubis to the sacral promontory, distance between the ischial spines and that of ischial tuberosity. Univariate analysis showed that there was no significant relationship between the above 7 pelvic measurement parameters and the occurrence of AL (all P>0.05). There was no significant relationship between branch patterns of IMA and AL after rectal cancer surgery ( P=0.712). Conclusion:AL as a severe postoperative complication in rectal cancer patients undergoing AR procedure were caused by multiple factors. Neither IMA branch patters nor pelvic imaging measurement seem to be related to the occurrence of AL after AR for rectal cancer.

The clinical experience of transurethral columnar balloon dilation of prostate for benign prostatic hyperplasia / 中华泌尿外科杂志

Objective:To summarize the clinical experience of transurethral columnar balloon dilation of prostate (TUCBDP) in the treatment of patients with benign prostatic hyperplasia(BPH).Methods:A retrospective analysis of 379 BPH clinical data from the Hubei Provincial Hospital of Traditional Chinese Medicine using TUCBDP was performed between June 2015 and June 2018.Their age was (71.3±14.5)years old. The history of disease ranged from 1 month to 36 years. The prostate volume was(47.4±2.1) ml. Preoperative maximum urinary flow rate was (Q max)(9±4) ml/s, postvoid residual urine(PVR) was (123.1±72.4) ml. Their international prostate symptom score (IPSS) was (21±6) points. The quality of life score (QOL)was (5±1) points. The international index erectile function questionnaire (IIEF-5)in 32 patients, who had sex before surgery, was 15±4. We set the time of catheter structure improvement in June 2016 as the boundary, including the early stage (June 2015 to May 2016, 121 cases) and the recent stage (June 2016 to June 2018, 258 patients). In the early stage, the principle of operation is the inner balloon of the catheter to dilate the membrane urethra, and the outer balloon to dilate the urethra of the prostate and the bladder neck. The main surgical steps include the insertion of a dilatation catheter, localization by touching the skin of the scrotum bottom, the inner and outer balloon are filled with water, the first time of drainage and decompression in the inner and outer balloon, the catheter continuous irrigation, drainage and decompression of the inner and outer balloon again, removing the dilatation catheter, and the ordinary urinary catheter was replaced and continuous irrigation. In the recent stage, the principle of surgery is that the inner balloon only served for positioning and fixation. The outer balloon is used to dilate the membrane urethra, prostate urethra, and bladder neck. The inner and outer balloon are drained and decompressed at one time after surgery. The main surgical steps are that the resectoscope was used to examine the bladder and urethra and to guide the dilatation catheter into the bladder. The apex of the prostate touching was used to conform the location. The inner balloon water filling was used for fix the positioning. The inner and outer balloon are filled with water, decompressed and pulled out for urination test, the gland expansion is observed under the resectoscope, and ordinary urinary catheter is replaced for continuous flushing. We observed the changes in Q max, PVR, IPSS, and QOL at 1, 3, 6, 12, and 24 months after the operation. the complications differences in two-stage patien, including the International Incontinence Advisory Committee Urinary Incontinence Questionnaire (ICI-Q-SF) score; those who had sex before surgery were recorded changes in the IIEF-5 score, was compared. Results:There were no deaths during and after operation in this study. The operation time was (18.5±6.7) min. The number of follow-up cases at 1, 3, 6, 12, and 24 months after operation were 326, 253, 201, 194, and 181, respectively. The Q max at 1, 3, 6, 12, and 24 months after operation were (17±9)ml/s, (15±2)ml/s, (12±4)ml/s, (13±6)ml/s and (13±4)ml/s, respectively. The PVR were (17.4± 11.6) ml, (20.6±9.8)ml, (25.4±13.1)ml, (31.5±11.5)ml, and (29.1±12.4)ml, respectively. The IPSS were(7±5) points, (4±4) points, (4±4) points, (6±5) points, (4±4) points, respectively. The QOL were (2±1) points, (2±1) points, (2±1) points, (2±1) points, and (2±1), respectively. All those results that were significantly different from those before surgery ( P<0.05). There were 32 patients who had sex before the operation. The postoperative IIEF-5 score was (17± 6), which was not significantly different from that before the operation ( P>0.05). Two patients had transient retrograde ejaculation, which relieved spontaneously within the 6 month. 4 cases with pseudourinary incontinence in the recent stage (1.5%) were not statistically different from 6 cases (4.9%) in the early stage ( P>0.05). one case(0.4%) of major bleeding in the recent stage was statistically different from 6 cases (4.9%) in the early stage ( P<0.05). 2 cases (0.7%) of patients with acute urinary retention in the recent stage were significantly different from 15 cases (12.4%) in the early stage ( P<0.05). Conclusions:TUCBDP has a positive overall effect and high safety. The major complications of surgery in the recent stage, except for pseudo-urinary incontinence, are significantly lower than that in the early stage, which may be related to the improvement of the catheter structure and the accumulation of clinical experience.

Research progress of long non-coding RNA regulates cancer cell signaling pathways / 实用肿瘤学杂志

To date,various kinds of long non-coding RNAs(lncRNAs)have been found using functional genomics.LncR-NAs can regulate gene expression,and play a significantly important role in the development of diseases including cancer.There are multiple mechanisms involved in the regulation of gene expression mediated by lncRNAs,such as the regulation of transcription,the process of translation,protein modification,and RNA-protein formation or protein-protein complex formation.In this review,we pri-marily discuss the latest research progress of the lncRNAs in the regulation of cancer cell signaling pathways.

Objective To investigate the protective effects of curcumin on the cellular model of Alzheimer's disease(AD) and the expression of growth associated protein-43(GAP-43). Methods Aβ25~35 was used to treat the hippocampus neurons of rat and the cellular model of AD was established. The survival rate was detected by MTT assay. The cells were randomly divided into blank control,model,curcumin 10 and 20μmol/L groups. The effect of curcumin on apoptosis was assayed by flow cytometry. The pro?trusive length and GAP-43 positive cell rate were detected by immunocytochemistry. The expression of GAP-43 was detected by West?ern blot. Results Compared with the model group,curcumin significantly reduced the toxicity of Aβ25~35,increased the survival rate and decreased the apoptosis rate of the cells(P<0.05). It also significantly increased the average protrusive length,GAP-43 positive cell rate and GAP-43 expression(P<0.05 or P<0.01). Conclusion The protective effect of curcumin on the cellular model of AD was likely related to the up-regulation of GAP-43 expression.

Meta analysis on the necessity for indwelling gastrointestinal decompression after gastrectomy / 中华普通外科杂志

Objective To evaluate the necessity of indwelling gastrointestinal decompression after gastrectomy. Methods Eight publications on the necessity of gastrointestinal decompression after gastrecomy were colleted, data on recovery time of gastrointestinal function and hospital stay, complications,and motality were Meta-analyzed using fixed effect model and random effect model. Results Eight randomized trails including 975 patients were qualified and included in this study. The differences in time to oral intake ( WMD =0. 61, 95% CI: 0. 17 - 1.05, P ＜ 0. 05 ) and hospital stay ( WMD = 1.20, 95% CI:0. 05 -2. 36, P ＜ 0. 05 ) between the decompression group and non-decompression group were statistically significant, but the difference in time to flatus (WMD = 0. 31,95% CI: -0. 07- 0. 69, P ＞ 0. 05 ) was not significant. There were no significant differences in complications such as nausea and vomiting ( OR = 1.43,95% CI: 0. 61 - 3.31, P ＞ 0. 05 ), pulmonary infection and atelectasis ( OR = 1.43, 95 % CI: 0. 82 - 2. 49,P＞0.05), anastomotic leakage (OR = 1.17, 95%CI: 0.54-2.49, P ＞0.05), abdominal abscess ( OR = 1.08, 95% CI: 0. 50 - 2. 34, P ＞ 0. 05 ), wound dehiscence ( OR = 1.47, 95% CI: 0. 43 - 4. 95,P ＞ 0. 05 ) between the two groups, except for fever ( OR = 1.76, 95% CI: 1.11 - 2. 78, P ＜ 0. 05 ), which was found more frequent in decompression group than in non-decompression group. Conclusions Routine gastrointestinal decompression after gastrectomy was not conductive to the recovery of gastrointestinal function, and could not reduce the incidence of postoperative complications. Postoperative GI decompression increased fever incidence rate and prolonged hospital stay.

Effects of metformin on osteoclasts differentiation in vitro / 中华骨科杂志

Objective To investigate the effects of mefformin on the differentiation of osteoclastas well as relative mechanism.Methods Raw264.7 cells from the murine macrophage cell line was used.Receptor activator of NF-κB ligand (RANKL) was used to stimulate osteoclast differentiation from Raw264.7 cells.Osteoclast differentiation was assessed by tartrate-resistant acid phosphatase (TRAP) and actin fluorescence staining and counting the TRAP-positive cells after exposure to different concentrations of mefformin (0 μmol/L,400 μmol/L,800 μmol/L and 1000 μmol/L) or rapamicin (100 nmol/L) in the presence of 50 ng/ml RANKL for 5 days.Bone-resorbing activity was evaluated by BD BioCoatTM OsteologicTM Bone Cell Culture System.The expression of osteoclast-specific genes like TRAP,capthesin K,calcitonin receptor (CTR) and matrix metalloproteinase (MMP-9) was evaluated by RT-PCR.The expression of tumor necrosis factor-α(TNF-ct) S6K1Thr389,S6 Ser235/236,4E-BP1Thr37/46 and c-Fos protein was evaluated by ELISA kit and Western blot analysis,respectively.Results Mefformin dose-dependently inhibited RANKL-stimulated osteoclasts differentiation in Raw264.7 cell culture,as manifested by decrease of TRAP-positive multinucleated cells and pit erosion area,down-regulation of TRAP,cathepsin K,CTR and MMP-9 mRNA and reduction of TNF-α and c-Fos protein expression.Further study revealed that RANKL activated mTOR complex 1(mTORC1) signaling,while mefformin impaired RANKL-stimulated mTORC1 signaling.Rapamycin,an mTORCl-specific inhibitor and immunosuppressive macrolides could also prevent RANKL-induced osteoclast differentiation and bone resorption in vitro.Conclusion Mefformin inhibits osteoclastogenesis in vitro,which may due to reduction of TNF-α and c-Fos protein expression,and mTORC1 signaling is involved in this process.

A new classification of spinal tuberculosis:based on MRI findings (Southern Medical University classification) / 中华骨科杂志

Objective To outline the classification of spinal tuberculosis based on MRI findings (Southern Medical University classification,SMU classification) and explore its use in the diagnosis,surgical protocols.Methods The MRI data from 230 cases with spinal tuberculosis were analyzed retrospectively.Our classification system was based on clinical and radiological criteria (abscess formation,disc degeneration,vertebral collapse,kyphosis,sagittal index,instability and neurological problems).The surgical strategies were made according with this classification.Results Two hundred and thirty cases with spinal tuberculosis were classified into the 5 types.There were signal change type (type Ⅰ) in 28 cases,abscess formation type (type Ⅱ) in 39,vertebral collapse type (type Ⅲ) in 78,canal compression type (type Ⅳ) in 46 and kyphosis type (type Ⅴ) in 39 respectively.In type I lesion,25 patients had been followed up.Twenty patients were treated medically.Recurrence of tuberculosis was found in 2 cases.Surgical meticulous debridements were done in 5 cases without recurrence.In type Ⅱa lesion,6 patients were treated medically.The other 6 patients underwent surgical meticulous debridement with recurrence occurred in one patient.There was no difference between medical and surgical treatment regarding outcomes in patients with type Ⅰ and Ⅱa lesion.In type Ⅱb-Ⅴ,surgical treatments were carried out according to the pathological changes.There was no difference between medical and surgical treatment regarding outcomes in the patients with type Ⅱb-Ⅴ.Conclusion The SMU classification helps in differentiating the various manifestations of spinal tuberculosis and appears to correlate with the surgical treatment of spinal tuberculosis.We believe that this new classification system can be used as a practical guide in the treatment of spinal tuberculosis.
