With more and more attention and investment on acupuncture scientific researches, considerable outcomes and achievements has been acquired, but the shortcoming of low transformation rate of acupuncture research achievements is gradually exposed. Nowadays there is no related report on this problem, so based on achievement translational research in other areas and practical situation of acupuncture, the existing problems and solutions are analyzed. As a result, the existing problems include (1) the research content is mainly basic research and clinical research but less acupuncture device research, leading to limited transformation efficiency; (2) the evaluation system and transformation pattern are still needed to be perfect. The solutions are (1) to properly evaluate the research achievements of acupuncture, (2) to advocate the concept and method of translational medicine, (3) to reform the policy and system, and (4) to establish valid platforms covering research, outcomes and transformation.

Objective To evaluate the effect of increasing sunshine time or 1, 25(OH)₂D₃ supplement on improving Vitamin D blood level and reduction of microalbuminuria in early stage diabetic nephropathy (DN) patients. Methods A total of 150 early stage type 2 DN patients with serum 25(OH)D₃ lower than 15 mg/L were included.The patients were divided into sunshine group (n=50), 1, 25(OH)₂D₃ supplement group (n=50), and control group (n=50).After three-month treatment, serum 25(OH)D₃ level and urinary albumin to creatinine ratio(ACR)were compared among these three groups. Results Before treatment, there were no differences in serum 25(OH)D₃, ACR, HbA1c among the three groups.After three-month treatment, serum 25(OH)D₃ level was significantly improved in sunshine group, and ACR was reduced significantly in both sunshine group and 1, 25(OH)₂D₃ group. Conclusion Increasing sunshine time can improve Vitamin D level and reduce microalbuminuria in early stage diabetic nephropathy patients.

OBJECTIVETo observe the effect of simvastatin carried by poly (lactide-co-glycolide) (PLGA) on residual ridge resorption following tooth extraction.

METHODSSixty male Wistar rats were divided into experimental groups and control groups (30 rats/group). PLGA was immediately implanted with or without simvastatin into extraction sockets of the mandibular incisors. Soft X-ray photography, bone mineral density (BMD) and histopathologic study were conducted at 7, 14, 28, 56, and 84 days after implantation.

RESULTSThe relative length values of residual alveolar ridge of the experimental groups were greater than those of the controls at 14, 28, 56, and 84 days after implantation, and there was a significant difference between the experimental and control groups (P < 0.05). The BMD of the specific region was higher in the experimental groups [(7.101 +/- 0.025), (7.178 +/- 0.039), and (7.162 +/- 0.052) g/cm(2)] than that in the control groups [(7.074 +/- 0.014), (7.117 +/- 0.012), and (7.059 +/- 0.037) g/cm(2)] (P < 0.05) after 28, 56, and 84 days. Light microscopy showed that bone formation rate and quality of the experimental group were better than those in the control group at the same time.

CONCLUSIONSSimvastatin carried by PLGA could induce bone formation of tooth socket. Local application of simvastatin would be potential to preserve the length and bone volume of alveolar ridge after tooth extraction.

OBJECTIVETo explore the diagnostic values of vestibular autorotation test (VAT) for patients with vertebrobasilar insufficiency (VBI).

METHODSVAT and videonystagmography ( VNG) were performed on 73 patients with VBI and 48 patients with peripheral vestibular lesions (contrast group). Parameters analyzed included Gain, phase and asymmetry of VAT, as well as the canal paresis (CP) of caloric test and results of optokinetic-pursuit tests in VNG. Positive result of the test could be defined if anyone of the parameters was abnormal.

RESULTSFor VAT test, Gain was enhanced in VBI group and was reduced in contrast group. In VBI group and contrast group, Gain enhanced showed in 47 (64.4%) cases and 5 (10.4%) cases, respectively (chi2 = 31.19, P < 0.01). Simultaneity, Gain reduced in 11 cases (15.5%) and 22 cases (45.8%), respectively (chi2 = 13.82, P < 0.01). But there was no statistics significant for results of the parameters of phase, asymmetry and integration between two groups. For VNG test, results with optokinetic-pursuit tests were more abnormal in VBI group than that in contrast group, which showed central lesions characteristics. Forty-four cases (60.3%) in VBI group and 10 cases (20.8%) in control group showed central lesions results with optokinetic-pursuit tests and visual fixation test (chi2 = 15.89, P < 0.01). Unilateral or bilateral CP showed in 33 cases (68.6%) in control group and 51 cases (69.9%) in VBI group with caloric test.

CONCLUSIONSGain of VAT is mostly enhanced in VBI group, and Gain as a main characteristic is reduced in patients with peripheral vestibular lesions. The Gain parameter is availability for assessing characteristics of vestibular lesions. Phase and asymmetry can be used to assess the vestibular function but can not indicate the characteristics of vestibular lesions.

Objective To analyze the characteristics of subjective visual horizontal ( SVH) and evaluate its clinical value for vestibular function in peripheral unilateral vestibular hypofunction ( UVH). Methods Eighty-five patients with UVH (study group) and 39 normal persons (control group) accepted vestibular function tests, including SVH, subjective visual vertical ( SVV ) and caloric test by video-nystagmography. The parameters of the angle of SVH and SVV, directional preponderance ( DP) and unilateral weakness(UW) of caloric test were observed. The correlation between SVH/SVV, DP, UW and the course of disease were investigated respectively. SPSS 16. 0 software was used to analyze the data. Results Reference range of SVH and SVV was from - 2° to 2° in the control group. Among the 85 patients, 46 cases(54. 1% ) and 43 cases(50. 6% ) had the abnormal values of SVH and SVV respectively, with no statistical significance( χ2 = 12. 5, P = 0. 481 ) by chi square test Fifty-five cases (64. 7% ) withabnormal DP had no statistical significance when compared with SVH and SVV respectively (χ2 values were 0. 19 and 2.86, respectively, P value were 0. 164, 0.067, respectively). In UVH, there were positive correlation between SVH, SVV and DP( r value was 0. 939, 0. 648, 0. 658, all P <0. 05) respectively, but no correlation between UW and SV H or SVV (r value was 0. 048, 0. 085, all P > 0. 05). According to the permutation and combination of the four parameters, positive or negative, three main groups could be defined [SVH(+)DP(+)UW( +), SVH( -)DP( +)UW( +), SVH( -)DP( -)UW( +); SVV( + ) DP ( +)UW( +), SVV( -)DP( +)UW( +), SVV( -)DP( -)UW( +)]. The course of disease in the three main groups was positively skewed distribution,with median of 5. 0, 10. 0, 15. 0 d and 5. 0, 9. 5, 14. 5 d respectively. By Kruskal-Wallis Test, χ2 value were 8. 80 and 6. 26, respectively( P value were 0.012, 0. 040, respectively), with statistical significance between the above three main groups. Conclusions The SVH value can evaluate the function of the otolithic. The angle of SVH and SVV are changing in the course of disease, SVH and SVV can be used as a guidance of the vestibular compensation evaluation.

OBJECTIVETo investigate the associations between periodontal diseases, presence of Porphyromonas gingivalis (P. gingivalis), serum levels of pro-inflammatory mediators and preterm low birth weight (PLBW).

METHODS60 women (30 PLBW and 30 healthy women), were recruited after postpartum within 3 days in this case-control study. Periodontal measurements including plaque index (PI), bleeding index (BI), probing pocket depth (PD) and clinical attachment loss (CAL) were assessed. The subgingival plaque was collected before periodontal examination and analysed by polymerase chain reaction (PCR) for the presence of the 16S rRNA gene specific to P. gingivalis, while the venous and umbilical cord blood specimens collected were determined by enzyme-linked immunosorbent assay (ELISA).

RESULTSThe PLBW cases had a poorer oral conditions and the presence of P. gingivalis was found in a higher proportion in the PLBW than the healthy pregnant (56.7% vs. 30.0%, P < 0.05). Both of the presence of periodontitis and P. gingivalis have been found to be associated weakly with a shorter gestational age and a lower birth weight (P < 0.05). The levels of IL-1beta, IL-6 and prostaglandin-E2 (PGE2) in both of the blood samples showed higer levels between the PLBW and normal groups (P < 0.01). The IL-1beta and PGE2 levels in maternal serum were higher with a severe periodontal disease in the PLBW group (P < 0.01).

CONCLUSIONThere may be a possible link between periodontal diseases and PLBW.
