Objective: To observe the clinical efficacy of heat-sensitive moxibustion plus medications on senile osteoporosis (SOP), and to explore the related mechanisms. Methods: A total of 70 elderly participants with osteoporosis were randomly divided into an observation group and control group, with 35 cases in each group. The control group was treated with conventional drugs, and the observation group was treated with heat-sensitive moxibustion on the basis of the conventional drugs. Both groups were treated for 3 months. Before and after treatment, assessed the visual analog scale (VAS) and Oswestry disability index (ODI) scores, determined the bone mineral density of the participants' lumbar spine (L2-L4) and left femoral neck, and detected the participants' serum bone morphogenetic protein-2 (BMP-2) and osteoprotegerin (OPG) levels. Results: After treatment, the VAS scores of both groups were lower than before treatment (both P<0.05), and the VAS score of the observation group was significantly lower than that of the control group (P<0.05). After treatment, the bone mineral density values of the lumbar spine and left femoral neck in both groups were significantly higher than before treatment (both P<0.05), and the bone mineral density values of the observation group were higher than those of the control group (P<0.05). After treatment, the ODI scores of the two groups were lower than those before treatment (both P<0.05), and the ODI score of the observation group was lower than that of the control group (P<0.05). After treatment, the serum BMP-2 and OPG levels in the observation group were significantly higher than those in the control group (both P<0.05). Conclusion: Heat-sensitive moxibustion plus medications for SOP can significantly relieve patients' pain, improve dysfunction, and increase bone density, which may be related to the improvement of the serum BMP-2 and OPG levels.

Objective To research reducing capacity and identification of aerobic denitrifiers WXZ-15 and WXZ-19. Methods Four factors three levels [L9(34)] orthogonal experiment was adopted to determine the best experimental condition for reducing capacity of aerobic denitrifiers WXZ-15 and WXZ-19.The tests were conducted to study the reducing capacity to reduce nitrate in the presence of NO2-and NO3-. Partial 16S-rRNA analysis was used to identify aerobic denitrifiers WXZ-15 and WXZ-19. Results The result of range analysis showed the best experiment condition of WXZ-15 aerobic denitrifier,in which COD/N was 10,rotating speed was 160 r/min,the inital NO2-concentration was 200 mg/L,initial pH was 7.5,and that of aerobic denitrifier WXZ-19,in which COD/N was 10,rotating speed was 160 r/min,inital NO2-concentration was 50 mg/L,initial pH was 7.5. Comparing experiment showed that the TN removing rates of aerobic denitrifiers WXZ-15 and WXZ-19 were 85.65% and 45.23% respectively,using NO3-as nitrogen source. While the TN removing rates of aerobic denitrifiers WXZ-15 and WXZ-19 were 52.32% and 35.40% respectively,using NO2-as nitrogen source. Conclusion Aerobic denitrifiers WXZ-15 and WXZ-19 are Delftia tsuruhatensi and Pseudomonas putida respectively.The reducing capacity of aerobic denitrifiers WXZ-15 and WXZ-19 is strong.

Long non-coding RNA ( LncRNA) is a class of transcript (>200 nucleotides) that do not encode proteins. It plays an important role in epigenetic regulation and gene expression at transcriptional or post transcriptional level. The abnormal expression of LncRNA may lead to various pathological processes. Diabetic retinopathy ( DR ) is a multifactorial disease. Recent studies have shown that many specific expressions of LncRNAs are closely related to the genesis of DR. In this review, we summarized the recent advances in the function of LncRNA, the regulatory mechanisms of LncRNA involved in the development of DR, and the related therapies.

AIM:To compare the clinical efficacy of three combined surgical treatments for cataract induced by silicone oil -filled eye.
METHODS: The data of 75 eyes of 75 patients with cataract induced by silicone oil-filled eye were reviewed. Those patients were divided into group A, B, C. The patients in group A were treated by phacoemulsification combined with silicone oil removal through pupil and IOL implantation, the patients in group B were treated by phacoemulsification combined with silicone oil removal through 23G vitrectomy system and IOL implantation, the patients in group C were treated by phacoemulsification combined with silicone oil removal through 20G vitrectomy system and IOL implantation. The operation time, intraocular pressure, best corrected visual acuity ( BCVA ) , discomfort days and complications before and after the surgery were compared.
RESULTS: The differences of the intraocular pressure were not statistically significant between the three groups after the surgery. The BCVA of the three groups were all improved, but the differences were not statistically significant between three groups. The differences in postoperative complications showed no statistically significant. Otherwise, group A and B cost less operation time. The discomfort days of group A were less than other groups.
CONCLUSION: Three different surgical methods were safe and effective, appropriate surgical approach could be chosen according to the patients' clinical manifestations. For patients with cataract induced by silicone oil-filled eye whose retina recovered well, phacoemulsification combined with silicone oil removal through pupil and IOL implantation is a time-saving, safe and effective method.

This paper aimed to introduce and review the antioxidant and material base of selaginella medicinal plants.On the basis of the systematic identification of selaginella medicinal plants,we found that the ethyl acetate extract and flavonoids could inhibit the activity of XOD,LOX or/and COX-2 to some extent.Fourteen biflavonoids,one flavonoid and five flavonoid glycosides have been isolated from three resource plants,among them five compounds were firstly reported and fifteen compounds were firstly isolated in selaginella plants.Amentoflavone (AME),robustaflavone and robustaflavone-4''-dimethylether are three common characteristic constituents of selaginella plants,which can act as marks of common active ingredients and be applied to evaluate the quality of selaginella.Further studies found that some plants had stronger anti-Coxsackie virus and anti-tumor effects,and their mechanisms were associated with inhibiting multiple oxidase and mitigating harm of free radicals due to whole function.

Objective To replicate the rats model of human metabolic syndrome (MS),determine the standard of the model,evaluate the success rate of model,provide the experimental basis for the study of the pathogenesis and therapeutic study of MS.Methods Eighty specific pathogen free male Wistar rats aged 7 weeks were randomly divided into the normal group (n =10) and the experimental group (n =70),which were respectively fed with normal diet and high fat,high sugar,high salt diet for 16 weeks.The rats' body weight,abdominal circumference,body length,blood pressure and fasting plasma glucose (FPG) were measured every 4 weeks.The experimental group rats were injected with streptozocin(STZ) 35mg/kg intraperitoneally once at the fifteenth week,the blood lipids (TC,TG,LDL-C and HDL-C) and FINS were measured,and HOMA-IR was calculated a week late.Results With the feeding time gradually extended,the rats' body weight,abdominal circumference,blood pressure,FPG,TG,TC,FINS,HOMA-IR and LDL-C levels were all significantly higher in the experimental group than in the normal group (P ＜ 0.05),while HDL-C was lower than that of the normal group (P ＜0.05).There was no significant difference in body length between the two groups(P ＞0.05).The success rate of MS rats models were 74.3％.Conclusion High fat,high sugar,high salt diet combined with a small dose of STZ intraperitoneal injection can successfully replicate the rat model of MS.This kind of rat models conforms to the pathological characteristic of MS,which can be easily operated and with high success rate.Therefore,it could be applied as an ideal MS animal model for the study of MS and drugs therapeutic effect.

Objective To establish an effective technique in reservation and function reconstruction of a leg, in which all the muscles except gastrocnemius necrosed induced by the delayed necrosis of all the intermuscular vessels, the foot was linked only by skin, fascia and tibia. Methods The leg was linked with foot only by the skin, fascia, caput mediale of gastrocnemius and tibia when all the muscles, intermuscular vessels and fibula were removed. The direct island flap of tibialis posterior artery was cut from the healthy limb and used to cover the 4/5 length and 1/3 circumference of bone-fascia raw surface, then to anastomose the both arteries of the flap and the caput lateral gastrocnemius when dividing the pedicles. As soon as the raw surface healed, fuse the ankle in the functional situation and fix the flexor and extensor tendon in the proper situation. Results With sufficient blood supply from the skin and fascia of the flap, the raw surface healed soon, the severe ischemia pain relieved, and the circulation and sensation recovered gradually. The crutching and walking function of the leg reconstructed at last. Conclusion When all the necrotic intermuscular vessels and muscles except caput mediale of gastrocnemius were removed, the necrosis may be delayed by means of reticular collateral circulation among skin, deep and superficial fascia and tibia of the injured limb. However, the blood supply is very little, the severe ischemia wound and ischemia pain can't be healed. Through the tibialis posterior artery direct island skin flap of the healthy leg to cover the dystrophic wounds, the blood supply of the leg can be improved. As a result, the leg survives and its function is reconstructed, and an eternal axial-pattern artery for the wound leg through arteries anastomosis is rebuilt.
