3.Far lateral lumbar disc herniation:recent progress in its treatment
Journal of Interventional Radiology 2015;(10):928-931
The concept of far lateral lumbar disc herniation was firstly reported by Abdullah in 1974. The diagnosis of far lateral lumbar disc herniation is based on the discography findings as well as on clinical manifestations. Far lateral lumbar disc herniation is a special type of lumbar disc herniation. Clinically, far lateral lumbar disc herniation is less seen than other types of lumbar disc herniation, it accounts for 0.7%-11.7% of total lumbar intervertebral disc protrusion. Although the incidence of far lateral lumbar disc herniation is lower, its symptoms are usually heavier and its protrusion sites are specific. Its treatment methods are more complex, including mainly conservative treatment, minimally invasive interventional therapy and surgical management, etc. This paper aims to make a review about the recent progress in its corresponding treatment.

Shanghai Journal of Acupuncture and Moxibustion 2016;35(7):833-835
Objective To observe the safety and severity of heat-sensitive moxibustion in treating poisonous snakebites-induced bladder dysfunction of different degrees.Method Twenty-six patients diagnosed with bladder dysfunction due to poisonous snakebites were examined by type-B ultrasonic scanning for residual urine volume and uroflowmetry. The patients were treated with heat-sensitive moxibustion. The residual urine volume and uroflowmetry parameters were compared between different severity degrees of bladder dysfunction before and after treatment.Result The residual urine volumes were changed significantly in the mild group and moderate group after treatment (P<0.01); the residual urine volume showed insignificant change after treatment in the severe group (P>0.05). The maximum urine flow rate (Qmax) was significantly changed in the mild group after the treatment (P<0.05); the Qmax was insignificantly changed in the moderate and severe groups after treatment (P>0.05).Conclusion Heat-sensitive moxibustion is significantly effective in treating mild-moderate bladder dysfunction due to poisonous snakebites, and it’s safe and reliable.

Chinese Journal of Zoonoses 2017;33(3):222-227
Influenza,caused by influenza virus,is a respiratory infectious disease with a serious hazard to human health.Prevention of influenza through vaccine development is the most effective strategy.It is important to build a rapid response platform for research and production of influenza vaccine.As virus vectors,live vaccine provides a new prevention and treatment way for infectious disease.Modified vaccinia virus Ankara(MVA) is a replication-deficient viral vector that is safe and can encode one or more foreign antigens and induce humoral and cellular immune response.MVA holds great promise as a vaccine platform.In this review,we discuss the use of MVA for vaccine development against influenza virus.
6.Research advances in glucocorticoid-induced growth retardation
Chinese Journal of Endocrinology and Metabolism 2021;37(1):64-68
Glucocorticoid is an important treatment for many pediatric diseases and it often leads to osteoporosis, osteonecrosis of the femoral head, and growth retardation. Among them, glucocorticoid-induced growth retardation has been a particular focus in the treatment of children patients, which leads to a decrease in final height. The mechanism of glucocorticoid-induced growth retardation is complex, and there is no safe and effective treatment.This article summarized the mechanisms underlying glucocorticoid-inhibited longitudinal bone growth and reviewed the potential therapeutic targets discovered in recent years.

AIM: To express the DT389-hbFGF (389 amino acid residues of the N-terminus of diphtheria toxin (human basic fibroblast growth factor) fusion protein for potential targeting therapy towards posterior capsule opacification (PCO) after cataract surgery.METHODS: The DNA of inactivated diphtheria bacillus and RNA of 12-week fetal brain cortex were extracted, respectively. The fragments of truncated diphtheria toxin (containing 389 amino acids of N-terminus, DT389) )and full-length human basic fibroblast growth factor(hbFGF) sequence (encoding 18kDa protein) were amplified by PCR. The two fragments were inserted into pGEX-4T-1 prokaryotic expression vector to obtain pGEX-DT389-hbFGF prokaryotic expression plasmid. After sequence analysis, the expressing plasmid was transformed into Escherichia Coli BL21 strain and expression was induced under IPTG. The expressed fusion protein was purified and identified.RESULTS: The gene fragments encoding DT389 and hbFGF were amplified and their gene sequences were confirmed. Hybrid gene expression plasmid pGEX-DT389 (hbFGF was constructed. The fusion protein DT389-hbFGF was expressed and purified.CONCLUSIONS: The successful cloning and expression of DT389-hbFGF immunotoxin provides a foundation for targeting therapy towards posterior capsule opacification.

Background Scarring of surgical area,the most important factor,leads to the failure of glaucoma filtering surgeries.Therefore,more and more attentions are paid to the causes and process of scar formation.Objective This study was to compare the differences of proliferation and migrating abilities of fibroblasts between filtering bleb scar tissue and normal Tenon capsular tissue,and to investigate the inhibitory effects of miRNA-200a (miR-200a) on biological behavior of conjunctival fibroblasts.Methods Normal Tenon capsular tissue and filtering bleb scar tissue were collected during the strabismus surgery and glaucoma filtering surgery,respectively for the primarily culture of fibroblasts.The proliferation (absorbency,A) of the cells was assayed by cell counting kit-8 (CCK8) method;the relative migrating distance of the cells was measured by cell scratch test;and the relative expressions of transforming growth factor-β1 (TGF-β1)mRNA and miR-200a mRNA in the cells were detected by realtime fluorescence quantitative PCR.TGF-β1 mimic of 0,1,2 and 5 ng/ml was added in the medium of human normal Tenon capsular-derived fibroblasts (HTFs),and 0.00,0.25,0.50,1.00 μg/ml TGF-β1 inhibitor was added in the medium of human scarring-derived fibroblasts (HSFs) for 24 hours,respectively,and CCK8 was used to evaluate the proliferation of the cells.The relative migrating distance as well as the relative expressions of miR-200a mRNA were analyzed in the 2 ng/ml TGF-β1 mimic-or 1.00 μg/ml TGF-β1 inhibitor-treated cells.Results The primary conjunctival presented the spindle and star-like in shape with large body and oval nuclei.The cells showed the positive response for keratin and vimentin antibodies.The A values were 1.476±0.110 in the HSFs and 0.958±0.074 in the HTFs,with a significant difference between them (t =24.900,P=0.016).The relative expressions of TGF-β1 mRNA were significantly higher in the HSFs than those in the HTFs,and the relative expressions of miR-200a were evidently lower in the HSFs than those in the HTFs,showing significant differences between them (t =6.358,P =0.024;t=7.394,P =0.018).Compared with the 2 ng/ml TGF-β1 mimic-treated HTFs,the relative migrating distance increased,while the expression level of miR-200a mRNA was significantly reduced in the 2 ng/ml TGF-β1 mimictreated HSFs (all at P<0.05);Compared with the 1.00 μg/ml TGF-β1 inhibitor-treated HTFs,the relative migrating distance decreased,but the expression level of miR-200a mRNA was significantly elevated in the 1.00 μg/ml TGF-β1 inhibitor-treated HSFs (all at P<0.05).Conclusions The proliferation and migrating abilities are stronger in the HSFs than those in the HTFs,which probably is regulated by the expression of miR-200a in the cells.The miR-200a plays a negative feedback for the effect of TGF-β1 promoting proliferation and migration of fibroblasts.
