Osteoporosis is a common senile bone metabolism disease， clinically characterized by decreased bone mass， destruction of bone microstructure， increased bone fragility， and easy fracture. It tends to occur in the elderly and postmenopausal women， seriously threatening the quality of life and physical and mental health of the elderly. At present， the treatment of osteoporosis is mainly based on oral western medicines， such as calcium， Vitamin D， and bisphosphonates. Still， there are drawbacks such as a long medication cycle and many adverse reactions. In recent years， due to the advantages of multi-component， multi-pathway， and multi-target， some traditional Chinese medicines and effective ingredients can regulate the osteogenic and osteoclastic differentiation process in both directions and are widely used in the prevention and treatment of osteoporosis. Hippophae rhamnoides is a commonly used herbal medicine， and its fruits are rich in flavonoids， polyphenols， fatty acids， vitamins， and trace elements， which have been proven to have a good anti-osteoporosis effect. Isorhamnetin is the main effective ingredient of Hippophae rhamnoides fruits， which has many pharmacological effects such as anti-inflammation， anti-oxidative stress， anti-aging， and anti-tumor. Studies have shown that isorhamnetin can participate in the regulation of bone metabolism and has a good anti-osteoporosis effect. However， the pharmacological effects and related mechanisms of isorhamnetin against osteoporosis have not been systematically summarized. Therefore， this paper reviewed the pharmacological effects and related mechanisms of isorhamnetin against osteoporosis by referring to relevant literature to provide more basis for the development and application of isorhamnetin.

Myocardial ischemia reperfusion injury(MIRI)has become one of the most serious complications affecting the clinical outcome of patients with cardiovascular diseases.The immune inflammatory response of macrophages is closely related to the occurrence and development of MIRI.Many studies have shown that the NF-κB signaling pathway can participate in MIRI regulation by influencing the polarization and inflammatory state of macrophages,pyrodeath,infiltration and other functions,and is a potential target for MIRI therapy.Therefore,this article will review the research progress of NF-κB signaling pathway between macrophage function and MIRI regulation.

Objective:To observe and evaluate the clinical effect of hyperbaric oxygen combined therapy on patients with non-arteritic anterior ischemic optic neuropathy (NAION).Methods:A total of 110 patients with NAION admitted to the Department of Ophthalmology of Zhengzhou Second Hospital from January 2017 to January 2019 who met the inclusion criteria were selected and divided into control group (55 cases) and hyperbaric oxygen group (55 cases) by random number table method. The control group was given conventional therapies such as hormone shock, microcirculation improvement, and nerve nutrition, while the hyperbaric oxygen group was given conventional treatment and hyperbaric oxygen therapy, with chamber pressure of 2.0 ATA, once a day, 10 times for a course of treatment for 30 days. The visual acuity, mean sensitivity (MS), mean defect (MD), pattern visual evoked potential (PVEP) amplitude, and latency period of the two groups were observed and analyzed to evaluate the efficacy of treatment. The effect of hyperbaric oxygen combined therapy on serum human chondroglycoprotein-39 (chtinase-3-like-1 protein, YKL-40) in patients with NAION was also observed.Results:Before treatment, there were no statistically significant differences in visual acuity, mean sensitivity, mean defect, PVEP amplitude, latency period, and serum YKL-40 between the two groups ( P>0.05). The visual MD in the hyperbaric oxygen group after treatment was lower than that in the control group after treatment and also lower than that before treatment in the same group, and the differences were statistically significant ( P<0.05). The visual acuity and MS in the hyperbaric oxygen group after treatment were higher than those in the control group and also those before treatment in the same group, and the differences were statistically significant ( P<0.05). The PVEP amplitudes of the patients in the hyperbaric oxygen group were higher than those in the control group and also those before treatment in the same group, and the latency period was earlier than that in the control group and also that before treatment in the same group, with statistically significant differences ( P<0.05). The level of serum YKL-40 reached the peak after 7 days of treatment. After 3, 7, 15 and 30 days of treatment, the levels of serum YKL-40 were all lower than those of the control group on the same day, with statistically significant differences ( P<0.05). After treatment, the total effective rate of the hyperbaric oxygen group (83.63%) was higher than that of the control group (74.55%), but there was no statistically significant difference ( P>0.05). Conclusion:Hyperbaric oxygen combined therapy can significantly improve the vision acuity, MS, MD, PVEP amplitude, and latency period of the patients with NAION, and reduce inflammatory response, which is beneficial to improve clinical efficacy.

Objective To evaluate the curative effect of percutaneous puncturing drainage in treating liver abscess,to analyze the factors affecting curative effect,and to discuss the methods ior reducing mortality and complication rate as well as for shortening hospitalization time.Methods Clinical data of 121 patients with liver abscess,who were admitted to authors' hospital during the period from January 2011 to January 2016,were retrospectively analyzed.For the patients with confirmed liver abscess,adequate antiinfective therapy was adopted,at the same time CT scan was performed to evaluate the liquefaction of lesion,and under CT guidance percutaneous puncturing drainage was carried out.The mortality,complication rate,hospitalization time and the factors affecting curative effect were analyzed.Results A total of 121 patients with liver abscess were enrolled in this study.Two patients died after percutaneous puncturing drainage,the mortality was 1.6％.The factors affecting mortality included old age,underlying disease,the diameter and solid components of abscess.Two patients developed peripheral hepatic abscess and abdominal wall abscess,the complication rate was 1.6％,and clinical cure was achieved after active treatment in these two patients.The main factor affecting complication rate was inappropriate surgical manipulation.Clinical cure was achieved in all 119 patients,with a cure rate of 98.3％,and the average hospitalization time was (15.1±6.0)days.The risk factors that affected hospitalization time included the number of abscess X6 (r=0.232,P=0.021),abscess size X7 (r=0.26,P=0.005) and white blood cell count X8 (r=0.238,P=0.009).Multiple linear regression equation analysis indicated that statistically significant correlation existed between the above influence factors and hospitalization time (P＜0.05).The multiple regression equation was as follows:Y=-3.438+3.055X6+0.527X7+0.297X8,F=5.819,R2=0.416.No statistically significant correlation existed between the hospitalization time and other factors,including gender,age,diabetes mellitus,pathogenic bacteria and location of abscess (P＞0.05).Conclusion Percutaneous puncturing drainage is an effective treatment for liver abscess,it carries lower mortality and lower complication rate,and its hospitalization time is short.(J Intervent Radiol,2017,

Objective　To develop a new method to induce the gene transfection in high efficiency for eukaryotic cells in vitro. Methods　 Four kinds of p14ARF gene primarily deleted human carcinoma cell line including H460,A549,U251,and PC-3 were transfected with the human p14ARF expression vector (pCI-neo-p14ARF) by using the new nonliposomal transfection reagent Fugene 6. The efficiency of gene transfer was determined by screening the cells in G418. Results　 After 21 days' selection, G418-resistant clones were shown in all the transfected plate. PCR product of p14ARF gene was positive in all the G418-resistant clones. Cytotoxicity of Fugene 6 was detected. The cell proliferation activity was not affected when it was cultured in a high dose of Fugene 6. Conclusion　 These results demonstrate that Fugene 6 is a rapid, feasible, reproducible, and noncytotoxic gene transfection approach for eukaryotic expression vector in vitro.

Objective　To examine whether wild-type p14ARF gene is a candidate suppressor gene for lung cancer. Methods　Human lung cancer cell lines having various endogenous backgrounds in INK4a, p53 and Rb genes were used as the recipients of the wild-type p14ARF gene. The expression of p14ARF mRNA and protein was detected with RT-PCR, immunohistochemistry and Western blot after G418 selection. Clones which expressed both p14ARF mRNA and protein were identified and selected for further experiements. By comparing with the parental and negative control cells treated with empty vectors, the effects of exogenously transfected p14ARF on cell division rate, cell cycle distribution and morphologic alteration were analyzed. In vivo evaluation of the growth rate was also made with the experiment of nude mice tumor formation. Results　Upon transfection with p14ARF gene, cells were arrested at G1 or G1／G2 phase of cell cycle in three wtp53 lung cancer cell lines and their proliferation rates were also inhibited. Conclusion　Human wild-type p14ARF gene has suppressive effect on abnormal proliferation of lung cancer cells, especially in some wtp53 lung cancer cells, and it might be an ideal candidate for gene therapy of human lung cancer.

p16 gene was a tumor supressor gene found recently. The p16 protein is a negative regulator of cell proliferation . Loss of normal p16 function is associated with the development of neoplasms. To detect antitumorigenic effect of p16 on human lung adenocarcinoma cells, we cloned a p16 cDNA into the pcDNA3 vector at the sites of BamHl and Xho I to gain a p16 gene recombinant expression vector plasmid. We then transferred the p16 gene recombinant plasmid into human lung adenocarcinoma cell line (NCI-H460) by electroporation method. After G418 selection we assessed cell growth properties and cell cycle pattern by flow cytometry to G418-resistant clones of NCI-H460-pl6 and NCI-H460-vect respectively. The results show that human p16 gene could suppress the phenotype of NCI-H460 cell line and p16 gene therapy plays a positive role in human lung adenocarcinoma treatment.
