Objective: To observe the clinical efficacy of heat-sensitive moxibustion plus Western medicine in treating patients with diabetic peripheral neuropathy (DPN). Methods: A total of 70 patients with DPN were divided into an observation group and a control group by sealed envelope method combined with the random number table method, with 35 cases in each group. The control group was treated with routine medicine, and the observation group was treated with heat-sensitive moxibustion on the basis of the treatment in the control group. After 2 courses of treatment, the scores of Toronto clinical scoring system (TCSS) and vibration perception threshold (VPT) in both groups were observed, and the clinical efficacy was compared. Results: During treatment, 3 cases dropped out in the control group and 4 cases in the observation group. After treatment, the total effective rate in the observation group was higher than that in the control group (P<0.05). The scores of TCSS and VPT in both groups decreased after treatment, and the intra-group comparison showed statistical significance (both P<0.05). The scores of TCSS and VPT in the observation group were lower than those in the control group, and the differences were statistically significant (both P<0.05). Conclusion: Heat-sensitive moxibustion plus Western medicine can improve the symptoms in patients with DPN, and has a better curative effect than the Western medicine alone.

MicroRNA (miRNA) is a class of naturally occurring short non-coding small molecular RNA with 19-25 nucleotide. MiRNA can regulate gene expression through incompletely binding to complementary sequences in the 3'UTR of target mRNA. MiRNA plays key regulatory role in a diverse rang of pathways, including cell proliferation, differentiation, apoptosis, stem cell development. Many studies have shown that many miRNA have a special role of gene regulation in cancer development and have been used as therapeutic targets and diagnostic markers of cancer. This review focuses on recent advances of studies on miRNA involved in tumorigenesis, and in classification, diagnosis, therapy and prognosis of DLBCL.

OBJECTIVETo study the inhibition effect of celastrol on neovascularization.

METHODSThe effect of celastrol on the in vitro proliferation of endothelial cell of vessel (ECV) was examined by MTT assay. The effect of celastrol on endothelial cell migration, tube formation on Matrigel and Chick chorioallantoic membrane angiogenesis was also examined. Matrigel plug assay was used to evaluate the effect of celastrol on angiogenesis in vivo.

RESULTSThe proliferation of ECV was inhibited significantly by celastrol with IC(50) being 1.33 microg/ml. Celastrol inhibited endothelial cell migration and tube formation in a dose-dependent manner. Celastrol also inhibited angiogenesis both in Matrigel plug of mouse model and in chick chorioallantoic membranes.

CONCLUSIONCelastrol, which can inhibit angiogenesis, could be developed as an antiangiogenic drug.

OBJECTIVETo investigate the clinical value of humidified high-flow nasal cannula (HHFNC) as a respiratory support after extubation by comparing it with nasal continuous positive airway pressure (NCPAP) in neonates with meconium aspiration syndrome (MAS) and persistent pulmonary hypertension of the newborn (PPHN).

METHODSA total of 78 neonates with MAS and PPHN were randomly administered with HHFNC or NCPAP immediately after extubation. The following indices were compared between the two groups: blood gas parameters, duration of noninvasive ventilation, rate of extubation failure, and incidence of complications, such as nasal damage, abdominal distension, and intraventricular hemorrhage.

RESULTSThere were no significant differences in the rate of extubation failure, PaO, PCO, and PaO/FiOratio at one hour after NCPAP or HHFNC, duration of noninvasive ventilation, time to full enteral feeding, length of hospital stay, and incidence of intraventricular hemorrhage between the two groups (P>0.05). The HHFNC group had significantly lower incidence of nasal damage (5.0% vs 31.6%; P<0.05) and incidence of abdominal distension (7.5% vs 34.2%; P<0.05) than the NCPAP group.

CONCLUSIONSBoth NCPAP and HHFNC can be used as the sequential therapy for neonates with MSA and PPHN after extubation, and they both have a definite effect. As a new strategy of respiratory support, HHFNC is better tolerated, and has fewer side effects than NCPAP.

OBJECTIVETo study the validity of criteria currently used in China for the classification of symmetric small for gestational age infants (SGA) as compared with its definition.

METHODSThis study included 417 inpatients diagnosed as SGA in authors' hospital from January 1998 to June 2002. Symmetric SGA was diagnosed by the following three criteria: (1) the Ponderal Index (PI), (2) the crown-heel length-to-head circumference ratio (BL/HC) issued in Chin J Pediatr (1988;26:164 - 165), as well as (3) the SGA definition. The definition criterion was considered as the "gold standard". The sensitivity, specificity, false positive and negative values, positive and negative predictive values, exact agreement ratio, diagnosis index, and Cohen's Kappa value were used to evaluate the validity and agreement of the methods of PI and BL/HC. Receiver Operating Characteristic (ROC) analysis was used to evaluate the validity of the diagnosis.

RESULTSOf 417 SGA infants, 376 (90.17%), 376 (90.17%) and 187 (44.84%) subjects were diagnosed as symmetric type with PI, BL/HC and the definition criteria, respectively. (2) The agreement rate and Kappa value between PI and BL/HC was 80.82% and -0.093 (SEM 0.026), respectively. And the agreement rates between PI or BL/HC and the definition criterion were 49.88% and 50.84%, respectively. As compared with the definition criterion, the PI and BL/HC methods had sensitivities of 91.8% - 96.4%, specificities of 9.3% - 25.9%, positive predictive values of 45.8% - 51.1%, negative predictive values of 72.7% - 82.8%, diagnosis indices of 4.9% - 17.7% and Kappa values of 0.070 - 0.167. (3) The areas under the ROC curves in full-term and preterm infants by PI method were 0.635 (95% CI, 0.573 - 0.697) and 0.698 (95% CI, 0.622 - 0.725), respectively. PI cutoffs at 2.47 in full-term SGA, at 2.43 in preterm SGA, and BL/HC cutoff at 1.43 produced the maximum diagnosis indices that were 24.7%, 39.6% and 33.7%, respectively. When the PI at 2.50 (full-term), PI at 2.31 (preterm) and BL/HC values at 1.46, the sensitivity closed mostly to the specificity. The sensitivities and specificities in full-term and preterm infants were 59.4% and 59.3%, 65.3% and 65.5%, and 66.3% and 65.5%, respectively.

CONCLUSIONIn the classification of SGA, the results showed a poor agreement between PI or BL/HC and the definition criterion. The results suggested that the current cutoffs of PI and BL/HC might not be appropriate for the diagnosis of symmetric SGA. Low AUC suggested that PI and BL/HC could not give a valid diagnosis at any cutoffs.

OBJECTIVESTo examine the gene expression profile of bone morphogenetic protein 2 (BMP-2) and vascular endothelial growth factor (VEGF) during entochondrostosis of mice and explore the expression rules and effects between BMP-2 and VEGF, and to detect the expression of VEGF in BMP-2 induced entochondrostosis in vivo.

METHODScDNA microarray technique with 34,000 genes was used to analyze the gene expression profiles during entochondrostosis in the limbs of mice embryo from E10 to E14. Pathway analysis of BMP-2 and VEGF was performed with GCOS1.2 software. An experimental model of femoral muscular pouch in 20 mice was adopted. The expression of VEGF was examined by in situ hybridization method and immunohistochemical method in BMP-2 induced entochondrostosis in vivo.

RESULTSThe expression signals of VEGF mRNA and VEGF appeared in cytoplasm during condensation of mesenchymal cell. As the mesenchymal cells differentiated into precartilage, the expression signals decreased in mesenchymal cells, but increased in chondrocytes and kept getting denser in the process of cartilage maturity. The peak expression of VEGF mRNA and VEGF in the experimental group appeared on the 14th day, accompanied by numerous hypertrophic chondrocytes. When mature cartilage calcified and new bone trabecula formed, the expression of VEGF mRNA and VEGF decreased in chondrocytes, but still expressed moderately in the osteoblasts and osteocytes.

CONCLUSIONSThe finding reveals a complex pattern of gene coexpression of BMP-2 and VEGF during the critical period of entochondrostosis. It's feasible for the clinical application of BMP-2 in orthopedics.

Diabetic macular edema(DME)and age-related macular degeneration(ARMD)are the leading causes of visual impairment and blindness worldwide, and their common pathological features are increased vascular permeability and abnormal neovascularization, in which cytokines such as vascular endothelial growth factor(VEGF)and angiopoietin-2(Ang-2)play an important role. Intravitreal injection of anti-VEGF agents significantly changed the clinical management of DME and ARMD, but limitations such as the non-responsive cases, the treatment burden and risks caused by frequent injections need to be overcome. Faricimab, a novel bispecific monoclonal antibody that simultaneously targets VEGF-A and Ang-2, can effectively reduce vascular permeability, decrease the number of neovascularization and alleviate retinal edema. Registered clinical studies have shown that Faricimab is effective in improving vision and reducing retinal edema, which is non-inferior to Aflibercept and Ranibizumab, maintains a long dosing interval, and has a high safety profile. This article reviews the latest advances in the treatment of DME and ARMD with Faricimab.

AIMA series of triazole antifungal agents were synthesized to search for novel triazole antifungal agents with more potent activity, less toxicity and broader spectrum.

METHODSTwenty-one 1-(1H-1, 2, 4-triazolyl)-2-(2, 4-diflurophenyl)-3-(4-substituted-1-piperazinyl)-2-propanols were synthesized, on the basis of the three dimensional structure of P450 cytochrome 14alpha-sterol demethylase (CYP51) and their antifungal activities were also evaluated.

RESULTSResults of preliminary biological tests showed that most of title compounds exhibited activity against the eight common pathogenic fungi to some extent and the activities against deep fungi were higher than that against shallow fungi. In general, phenyl and pyridinyl analogues showed higher antifungal activity than that of the phenylacyl analogues.

CONCLUSIONSeveral title compounds showed higher antifungal activities than fluconazole and terbinafine. Compound VIII-1, 4, 5 and IX-3 showed the best antifungal activity with broad antifungal spectrum and were chosen for further study.
