Objective To explore a reasonable treatment for intertrochanteric hip fractures in the aged patients by comparing the fixation effects of cannulated compression screws and intramedullary fixation nails. Methods From January 1998 to December 2004, in our department 123 old patients with intertrochanteric hip fracture were fixed with cannulated compression screws or intramedullary nails. They were followed up and their complete clinic data kept. According to the Evans classification, of the 51 patients who received treatment with cannulated compression screws for their anterograde intertrochanteric hip fracture, 14 were type Ⅰ , 24 type Ⅱ , 10 type Ⅲ and three type Ⅳ , while of the 72 patients who received treatment with intramedullary nailing, 10 were type Ⅰ , 12 type Ⅱ , 28 type Ⅲ , 14 type Ⅵ , and eight retrograde intertrochanteric hip fractures. A retrospective comparison was made between the old patients treated with the two different fixation devices in terms of operative time, blood loss, transfusion, average hospitalization time, intraoperative and postoperative complications, functional recovery one year postoperatively and treatment expenses. Results The differences between the two groups in operative time, blood loss, transfusion, treatment expenses were of statistical significance (P0.05). Conclusions Cannulated compression screws should be chosen for old patients with anterograde intertrochanteric hip fractures of Evans types Ⅰ & Ⅱ or of Evans types Ⅲ & Ⅳ who are at a high risk, in a poor health or severely osteoporotic state. For patients with unstable Evans types Ⅲ & Ⅳ or with retrograde intertrochanteric hip fractures, intramedullary nails are suitable.

Objective To compare the short‐term clinical effects of single segment and two segments of Dynesys dynamic in‐ternal fixation system for treating lumbar degenerative disease .Methods 40 cases of degenerative lumbar disease treated by the Dynesys dynamic fixation system combined with posterior approach decompression from 2009 July to March 2012 were selected and performed the evaluation on the clinical effects by the waist and leg pain visual analogue scale (VAS) ,the Oswestry disability index (ODI) and the orthopaedic spinal association of North America (NASS) index .The imaging method was used to observe the mobili‐ty of operative segment and proximal adjacent segment and the degenerative change of intervertebral height .Results All of the 40 cases were followed up .The VAS score and ODI score at postoperative 3 months and last follow‐up were significantly decreased when compared with the pre‐operative scores (P<0 .05);there was no statistically significant differences in the VAS score and ODI score at 3 months and last follow‐up between the single segment group and the 2‐segment group (P> 0 .05) .The NASS index showed no statistically significant difference in the postoperative effect satisfaction between the two groups (P>0 .05);there was no statistically significant difference in the variation of the intervertebral height between before operation and at the last follow‐up (P>0 .05) .There was statistically significant difference in the motility of proximal adjacent segment at the last follow‐up between the two groups (P<0 .05);but comparing the motility of proximal adjacent segment between the last follow‐up and pre‐operation , only the single segment group showed statistically significant difference (P< 0 .05) .Conclusion The Dynesys dynamic fixation system combined with posterior approach decompression operation has good clinical effect in the treatment of lumbar degenerative disease .Meanwhile ,the single segment method has more significant effect on the motility of proximal adjacent segment than the double segments method .

AIM: To illuminate the effect of SWI/SNF-related, matrix-associated, actin-dependent regulator of chromatin, subfamily b, member 1 (SMARCB1) in early diagnosis and prognosis of hepatocellular carcinoma (HCC) by determining the clinical expression of SMARCB1 in HCC tissue and benign liver tissue.METHODS: The specific target gene SMARCB1 was selected from these genes by using The Cancer Genome Atlas (TCGA).SMARCB1 expression in HCC tissue and benign liver tissue was measured by immunohistochemistry.Further statistical analysis of TCGA was performed to illuminate the role of SMARCB1 on HCC occurrence and progression.RESULTS: Compared with the benign liver tissue, immunohistochemical staining showed that SMARCB1 expression was significantly up-regulated in the HCC tissue (P<0.01).In addition, SMARCB1 expression was significantly associated with advanced tumor stage (P<0.05).The relation between SMARCB1 expression at mRNA level and clinical prognosis was analyzed.The results indicated that high SMARCB1 expression was an independent prognostic factor for HCC (P<0.05).CONCLUSION: SMARCB1 may play a part as a carcinogenic gene in tumorigenesis.We can distinguish primary HCC samples from non-malignant samples according to its different clinical expression.High SMARCB1 expression probably predicts poor outcome in HCC patients.

Objective To investigate the mechanism of traditional Chinese medicine (TCM) Sheshang capsule for treatment of blood coagulation dysfunction in patients bitten by Trimeresurus stejnegeri snake. Methods A prospective study was conducted. Seventy Trimeresurus stejnegeri snake envenoming patients whose manifestations conformed to the diagnostic criteria of the fire toxin syndrome in TCM were assigned into therapy group and control group by random number table (each, 35 cases). The basic treatments (including wound disinfection, intramuscular injection of 1 500 U tetanus antitoxin, conventional dose of antibiotics, 10 mg dexamethasone, 40 mg omeprazole) and 10 Jidesheng Sheyao tablets three times a day were applied in the control group. In the therapy group, the basic treatments the same as those of the control group were given, and in the mean time 5 Sheshang capsules (the drug was prepared in our hospital including ingredients:rhubarb, coptidis rhizoma, pleione bulbocodioides, elecampane inula root, bayberry bark, borneol and so on) were administered three times a day. The therapeutic course in the two groups was 1 week. The levels of platelet α-granule membrane protein (CD62p), thromboxane B2 (TXB2), platelet factor 3 (PF3) and von Willebrand factor (vWF) in serum were measured by enzyme linked immunosorbent assay (ELISA) before and after treatment. Results Before treatment, there were no significant differences in CD62p, TXB2, PF3 and vWF between therapy group and control group [CD62p (μg/L):3.81±1.64 vs. 3.52±1.43, TXB2 (μg/L):13.04±1.67 vs. 13.31±1.14, PF3 (μg/L): 2.84±1.08 vs. 2.88±1.23, vWF (μg/L):12.36±2.42 vs. 11.89±2.08, all P>0.05]. After treatment, the levels of CD62p, TXB2 and PF3 were increased, while vWF decreased compared with those before treatment in both groups, the level changes in therapy group being more remarkable [CD62p (μg/L): 6.73±1.77 vs. 5.81±1.62, TXB2 (μg/L):18.65±1.77 vs. 17.90±1.68, PF3 (μg/L):5.61±1.48 vs. 4.77±1.24, vWF (μg/L):3.87±1.01 vs. 4.58±1.09, P < 0.05 or P < 0.01]. Conclusion The Sheshang capsule is capable of treating patients with blood coagulative disorder after Trimeresurus stejnegeri snake bite, and its mechanism is possibly related to the improvement of platelet activation function and amelioration of the damage of vascular endothelial cells.

Near-infrared spectroscopy(NIRS) combined with band screening method and modeling algorithm can be used to achieve the rapid and non-destructive detection of the traditional Chinese medicine(TCM) production process. This paper focused on the ginkgo leaf macroporous resin purification process, which is the key technology of Yinshen Tongluo Capsules, in order to achieve the rapid determination of quercetin, kaempferol and isorhamnetin in effluent. The abnormal spectrum was eliminated by Mahalanobis distance algorithm, and the data set was divided by the sample set partitioning method based on joint X-Y distances(SPXY). The key information bands were selected by synergy interval partial least squares(siPLS); based on that, competitive adaptive reweighted sampling(CARS), successive projections algorithm(SPA) and Monte Carlo uninformative variable(MC-UVE) were used to select wavelengths to obtain less but more critical variable data. With selected key variables as input, the quantitative analysis model was established by genetic algorithm joint extreme learning machine(GA-ELM) algorithm. The performance of the model was compared with that of partial least squares regression(PLSR). The results showed that the combination with siPLS-CARS-GA-ELM could achieve the optimal model performance with the minimum number of variables. The calibration set correlation coefficient R_c and the validation set correlation coefficient R_p of quercetin, kaempferol and isorhamnetin were all above 0.98. The root mean square error of calibration(RMSEC), the root mean square error of prediction(RMSEP) and the relative standard errors of prediction(RSEP) were 0.030 0, 0.029 2 and 8.88%, 0.041 4, 0.034 8 and 8.46%, 0.029 3, 0.027 1 and 10.10%, respectively. Compared with the PLSR me-thod, the performance of the GA-ELM model was greatly improved, which proved that NIRS combined with GA-ELM method has a great potential for rapid determination of effective components of TCM.

Osteoporotic vertebral compression fracture (OVCF) can lead to lower back pain and may be even accompanied by scoliosis, neurological dysfunction and other complications, which will affect the daily activities and life quality of patients. Vertebral augmentation is an effective treatment method for OVCF, but it cannot correct unbalance of bone metabolism or improve the osteoporotic status, causing complications like lower back pain, limited spinal activities and vertebral refracture. The post-operative systematic and standardized rehabilitation treatments can improve curative effect and therapeutic efficacy of anti-osteoporosis, reduce risk of vertebral refracture, increase patient compliance and improve quality of life. Since there still lack relevant clinical treatment guidelines for postoperative rehabilitation treatments following vertebral augmentation for OVCF, the current treatments are varied with uneven therapeutic effect. In order to standardize the postoperative rehabilitation treatment, the Spine Trauma Group of the Orthopedic Branch of Chinese Medical Doctor Association organized relevant experts to refer to relevant literature and develop the "Guideline for postoperative rehabilitation treatment following vertebral augmentation for osteoporotic vertebral compression fracture (2022 version)" based on the clinical guidelines published by the American Academy of Orthopedic Surgeons (AAOS) as well as on the principles of scientificity, practicality and advancement. The guideline provided evidence-based recommendations on 10 important issues related to postoperative rehabilitation treatments of OVCF.

To address the increasing need for detecting and validating protein biomarkers in clinical specimens, mass spectrometry (MS)-based targeted proteomic techniques, including the selected reaction monitoring (SRM), parallel reaction monitoring (PRM), and massively parallel data-independent acquisition (DIA), have been developed. For optimal performance, they require the fragment ion spectra of targeted peptides as prior knowledge. In this report, we describe a MS pipe-line and spectral resource to support targeted proteomics studies for human tissue samples. To build the spectral resource, we integrated common open-source MS computational tools to assemble a freely accessible computational workflow based on Docker. We then applied the workflow to gen-erate DPHL, a comprehensive DIA pan-human library, from 1096 data-dependent acquisition (DDA) MS raw files for 16 types of cancer samples. This extensive spectral resource was then applied to a proteomic study of 17 prostate cancer (PCa) patients. Thereafter, PRM validation was applied to a larger study of 57 PCa patients and the differential expression of three proteins in prostate tumor was validated. As a second application, the DPHL spectral resource was applied to a study consisting of plasma samples from 19 diffuse large B cell lymphoma (DLBCL) patients and 18 healthy control subjects. Differentially expressed proteins between DLBCL patients and healthy control subjects were detected by DIA-MS and confirmed by PRM. These data demonstrate that the DPHL supports DIA and PRM MS pipelines for robust protein biomarker discovery. DPHL is freely accessible at https://www.iprox.org/page/project.html?id=IPX0001400000.
