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.

<p><b>OBJECTIVE</b>To investigate the antitumor effect of arsenic trioxide (ATO) combined with itraconazole (ITRA) on human multiple myeloma NCI-H929 cells by synergistically inhibiting Hedgehog (HH) signaling pathway.</p><p><b>METHODS</b>The inhibitory rate of NCI-H929 cells was assayed by MTT method. Tumor weight, tumor weight inhibition rate, and tumor volume of mouse model with multiple myeloma were examined. The ELISA were appled to detect the M-protein, qPCR and Western blot were used respectively to detect the expression level of Ptch, SMO, Gli and downstream target genes, the survival rate of tumor-bearing mice was analyzed.</p><p><b>RESULTS</b>ATO combined with ITRA significantly inhibited NCI-H929 cell proliferation as compared with a single administration. The combination of ATO and ITRA could synergistically inhibit tumor growth and obviously reduced tumor burden, survival time of tumor-bearing mice was significantly prolonged. qPCR and Western blot results confirmed that the ATO combined with ITRA could significantly down-regulated expression of Gli1, leading to significantly decrease of cyclinD1 and BCL-2 expression levels.</p><p><b>CONCLUSION</b>ATO combined with ITRA can more strongly suppress the growth of multiple myeloma NCI-H929 cells, as compared with a single administration. The synergistic effect of ATO and ITRA significantly down-regulates expression of Gli1 in HH signaling pathway, moreover the inhibition of target gene overexpression may be one of two drug mechanisms.</p>

Human diphyllobothriasis is a widespread fish-borne zoonosis caused by the infection with broad tapeworms belonging to the genus Diphyllobothrium. In mainland China, so far 20 human cases of Diphyllobothrium infections have been reported, and the etiologic species were identified as D. latum and D. nihonkaiense based on morphological characteristics or molecular analysis. In the present study, proglottids of diphyllobothriid tapeworms from 3 human cases that occurred in Heilongjiang Province, China were identified as D. nihonkaiense by sequencing mitochondrial cytochrome c oxidase subunit I (cox1) and NADH dehydrogenase subunit 5 (nad5) genes. Two different cox1 gene sequences were obtained. One sequence showed 100% homology with those from humans in Japan. The remaining cox1 gene sequence and 2 different nad5 gene sequences obtained were not described previously, and might reflect endemic genetic characterizations. D. nihonkaiense might also be a major causative species of human diphyllobothriasis in China. Meanwhile, the finding of the first pediatric case of D. nihonkaiense infection in China suggests that infants infected with D. nihonkaiense should not be ignored.

ObjectiveTo investigate fecal diversion in the management of pelvic fractures associated with perineal injuries.MethodsThis retrospective study involved 27 patients of pelvic fractures associated with perineal injuries during April 2005 to April 2011.There were 23 males and 4 females,and the mean age was 32.9 years old (range,16-62 years old).Fractures type according to Tile classification:4 cases were type A,10 cases were type B,and 13 cases were type C.The pelvic external fixator and fecal diversion were selectively used.Results Of the 27 patients of pelvic fractures associated with perineal injuries,24survived.The overall mortality of pelvic fractures associated with perineal injuries in the present study was 11％.The survived 24 patients were totally reviewed clinically.The mean follow-up time of these patients was 10.9 months (range,4-42 months).Of those patients who underwent early fecal diversion (＜ 48 h),none experienced infectious completions.However,of those underwent non-early (＞48 h) fecal diversion (including those who did not undergo fecal diversion),four patients experienced infectious completions.Fisher's exact test was used to compare the infection rate of these two groups.And the result of Fisher's exact test demonstrated that those patients who underwent early (＜ 48 h) fecal diversion and non-early (＞48 h) fecal diversion (including those who did not undergo fecal diversion).ConclusionStabilization of hemodynamic; selective fecal diversion; early stabilization of pelvic fracture are necessary for the emergency management of pelvic fractures associated with perineal injuries.Rectal injury and severe perineal injury without involvement of rectum should undergo fecal diversion.Early fecal diversion (＜ 48 h) could reduce the infection rate of pelvic fractures associated with perineal injuries.
