OBJECTIVE: To summarize the regulatory effect of non-coding RNA (ncRNA) on type H vessels angiogenesis of bone. METHODS: Recent domestic and foreign related literature about the regulation of ncRNA in type H vessels angiogenesis was widely reviewed and summarized. RESULTS: Type H vessels is a special subtype of bone vessels with the ability to couple bone formation. At present, the research on ncRNA regulating type H vessels angiogenesis in bone diseases mainly focuses on microRNA, long ncRNA, and small interfering RNA, which can affect the expressions of hypoxia inducible factor 1α, platelet derived growth factor BB, slit guidance ligand 3, and other factors through their own unique ways of action, thus regulating type H vessels angiogenesis and participating in the occurrence and development of bone diseases. CONCLUSION At present, the mechanism of ncRNA regulating bone type H vessels angiogenesis has been preliminarily explored. With the deepening of research, ncRNA is expected to be a new target for the diagnosis and treatment of vascular related bone diseases.

Objective To investigate the efficacy and mechanism of action of Compound Chaijin Jieyu Tablets (复方柴金解郁片, CCJJYT) in rats with insomnia complicated with depression. Methods Seventy-two Sprague-Dawley rats were randomly assigned into eight groups: the control, chronic unpredictable mild stress (CUMS), sleep deprivation (SD), CUMS + SD, positive drug (venlafaxine hydrochloride + diazepam), CCJJYT high-dose (CCJJYT˗2×), medium-dose (CCJJYT˗1×), and low-dose (CCJJYT˗0.5×) groups, with nine rats in each group. Depression-like behavior was evaluated by body weight, food intake, and behavioral tests such as the sucrose preference test (SPT), open field test (OFT), forced swimming test (FST), and pentobarbital-induced sleep test (PST). Hematoxylin-eosin (HE) staining and Golgi-Cox staining were used to observe changes in pathological tissue and synaptic morphology, respectively. Enzyme-linked immunosorbent assay (ELISA) was used to detect the contents of orexin-A and acetylcholine. The expression levels of orexin receptor 1 (OXR1), melatonin receptor 1 (MT1A), melatonin receptor 2 (MT1B), acetylcholinesterase (AChE), and choline acetyltransferase (ChAT) were detected by immunohistochemistry and Western blot. Results In the present study, rats in the model group showed significant behavioral changes as well as a reduction in hippocampal dendritic branch length and synaptic number, along with increasing the content of orexin A and acetylcholine (P< 0.05), and altered expression levels of OX1R, MT1A, MT1B, ChAT, and AChE in the hippocampus and prefrontal cortex after modeling (P < 0.05). CCJJYT can improve depressive insomnia behavior and synaptic plasticity of rats (P < 0.05), which is similar to that of the positive drug group. It can also decrease the content of orexin A and acetylcholine, and reduce the expression levels of OXR1 and ChAT in hippocampus and prefrontal cortex (P < 0.05), and increase the expression levels of MT1A, MT1B, and AChE proteins (P < 0.05). Conclusion CCJJYT has good antidepressant and insomnia effects, probably through the regu-lation of orexin-A, melatonin, and acetylcholine content in hippocampus and prefrontal cortex of rats, improving synaptic plasticity and thus exerting antidepressant and insomnia effects.

Objective:To evaluate the effectiveness of anterior minimally invasive osteosynthesis using a locking compression plate for spiral fractures of the mid-distal humeral shaft.Methods:A retrospective analysis was made of the clinical data of 12 patients who had undergone anterior minimally invasive osteosynthesis using a locking compression plate for spiral fractures of the mid-distal humeral shaft between December 2016 and January 2018. They were 8 males and 4 females, aged from 18 to 38 years (mean, 21.8 years). According to the AO/OTA classification, 5 cases were defined as type 12-A1.2, 2 as type 12-A1.3, 2 as type 12-B1.2, 2 as type 12-B1.3 and one as type 12-C1.1. The operation time, intraoperative blood loss, early postoperative complications and union time were recorded; the functional recovery of the elbow joint was evaluated by the Mayo elbow performance score (MEPS) and that of the shoulder by the University of California at Los Angeles (UCLA) shoulder rating scale at the final follow-up.Results:The mean operation time was 63 minutes (range, from 43 to 130 minutes), and the mean intraoperative blood loss 139 mL (range, from 60 to 280 mL). All incisions healed by the first intention without any neurologic complications or wound infection. All the 12 patients were followed up for 10 to 21 months (mean, 13.7 months). Bony union was obtained in all cases after 11 to 20 weeks (mean, 15.8 weeks). No loosening or breakage of internal fixation occurred. At the final follow-up, the MEPS ranged from 90 to 100 (mean, 99) and the UCLA shoulder scores from 31 to 35 (mean, 34.5).Conclusion:Anterior minimally invasive osteosynthesis using a locking compression plate is safe and feasible for spiral fractures of the mid-distal humeral shaft, leading to minimal invasion, a low risk for iatrogenic nerve injury and satisfactory effectiveness.

OBJECTIVE: To explore the effect of mild hypothermia on inflammatory response and angiogenesis in brain tissues of rats with intracerebral hemorrhage (ICH) and its possible mechanism for improving behavioral deficits of the rats After ICH. METHODS: A total of 120 healthy male SD rats were randomly divided into sham operation group, ICH group and mild hypothermia group. Rat models of ICH were established in the latter two groups by stereotactic injection of autogenous blood in the brain, and the rats in the sham operation group received injection of normal saline in the same manner. At 15 min after modeling, the rats in hypothermia group were subjected to mild hypothermia (30-32 ℃) for 8 h followed by rewarming (37-38 ℃); the body temperature was maintained at 37-38 ℃ in the other two groups. At 2, 4, 7, 14 and 21 days after the treatment, Longa scoring, balance beam scoring and Berderson scoring were used to evaluate the behavioral deficits of the rats. Immunohistochemical staining was used to detect the protein expressions of tumor necrosis factor-α (TNF-α) and nuclear factor-κB (NF-κB) in the brain tissue of the rats, and the mRNA expressions of α subunit of hypoxia-inducible factor 1 (HIF1-α) and vascular endothelial growth factor (VEGF) were detected using RT- PCR. RESULTS: At 2, 4, 7, 14 and 21 days after the treatment, the behavioral scores of the rats were significantly higher in ICH group and mild induced hypothermia group than in the sham operation group ( < 0.05 or 0.01). The protein expressions of TNF-α and NF-κB and mRNA expressions of HIF1-α and VEGF were significantly higher in ICH group and mild hypothermia group than in the sham operation group ( < 0.01). The behavioral scores were significantly lower in mild hypothermia group than in ICH group ( < 0.05), and the protein expressions of TNF-α and NF-κB were lower and the mRNA expressions of HIF1- α and VEGF were higher in mild hypothermia group than in ICH group ( < 0.05 or 0.01). CONCLUSIONS Mild hypothermia can improve behavioral deficits in rats with ICH possibly by antagonizing brain inflammation and promoting angiogenesis.

BACKGROUND: Insufficient bone mass in the posterior maxilla region often increases the difficulty of dental implantation. The application of maxillary sinus floor elevation successfully solves this problem. In the surgery bone grafting can be used to obtain sufficient bone mass. However, nonuse of graft materials can shorten the cycle of patient's treatment and reduce trauma and cost. OBJECTIVE: Combining the latest relevant research trends, to review the advances in the study of maxillary sinus floor elevation with and without bone grafting. METHODS: The first author searched PubMed, VIP, WanFang and CNKI databases using computer for relevant articles published from January 1985 to August 2018. The key words were "dental implant, maxillary sinus, bone augmentation, bone substitute" in English and Chinese, respectively. Finally, 78 articles were included in result analysis after screening and summarizing. RESULTS AND CONCLUSION: Ideal results can be achieved in the maxillary sinus floor elevation with or without simultaneous bone grafting In addition, the nonuse of grafting materials have the advantages of simplifying surgical procedures, shortening treatment cycles, reducing trauma and pain, reducing treatment costs, reducing complications and failure rates, thus gaining the favor of doctors and patients. Therefore, the maxillary sinus floor elevation without simultaneous bone grafting will be the primary choice of the doctors engaged in dental implantation in the future.

Objective To evaluate the effect of compound glycyrrhizin on the prevention and cure of cytarabine syndromes. Methods A total of 130 patients with hematological malignancies treated by moderate or high dose of cytarabine in the 303th Hospital of PLA from July 2010 to July 2016 were included. Patients were randomly divided into the control group and the experiment group by using random number table method, and each group had 65 patients. In the control group, patients were treated with cytarabine alone. In the experiment group, patients were treated with cytarabine plus compound glycyrrhizin. Skin rash and fever in patients of the two groups were also recorded. Results of blood routine tests, liver and kidney function tests were monitored during the treatment. Results Sixty-one patients in the experiment group and 63 patients in the control group were enrolled finally. In experiment group and control group, the differences in the incidence of cytarabine syndromes [8.2 % (5/61) vs. 41.3 % (26/63), χ2＝ 18.1, P < 0.001], skin rash [1.6 % (1/61) vs. 12.7 % (8/63), χ2＝16.3, P <0.001], and fever [6.6 % (4/61) vs. 36.5 % (23/63), χ2＝5.63, P <0.017] were statistically significant. There was no significant difference of the incidence of liver injury and minimum blood cell count between the two groups (P＞ 0.05). Conclusion Compound glycyrrhizin can effectively reduce the incidence of cytarabine syndromes, but the larger size and multiple center studies are needed to further verify the effect.
