Biotechnology supremacy is a newly-advanced power theory. It is a superior dominance of military biotechnological application based on the microcosm of life structure within a certain period of time. The advancement of biotechnology supremacy and modern biotechnology has created the concept of bio-micro-frontier, which involves information and defense resources of all living ultra-micro-organisms with national and regional characteristics. Being feasible both in theory and practice, the implementation of bio-micro-frontier system is strategically important. This article explores the implementation of bio-micro-frontier in terms of strategy and tactics, which will add a unique dimension to future military transformation and active defense.

Objective To investigate the changes of peripheral blood Foxp3+ regulatory T cell (Treg cell) in patients with ovarian cancer (OC).Methods In 46 patients with OC and 46 normal controls,the percentage of peripheral blood CD4+ Foxp3+ Treg cell was assessed by flow cytometry and Foxp3 mRNA level was detected by real-time quantitative reverse transcription polymerase chain reaction.The level of plasma.transforming growth factor β1 (TGF-ββ 1) was measured by enzyme linked immunosorbent assay.Results The percentages of CD4+ Foxp3+ Treg cell,Foxp3 mRNA and level of plasma TGF-β1 in patients with OC were statistically higher than those in normal controls [(11.42 ± 2.67)％ vs.(8.94 ± 1.98)％,0.59 ± 0.21 vs.0.37 ±0.14,(35 580 ±7274) ng/L vs.(28 610 ±5631) ng/L,P=0.0000].Conclusion The number and/or function of CD4+ Foxp3+ Treg cell in peripheral blood of patients with OC are abnormal,CD4+ Foxp3+Treg cell may participate in the occurrence of OC.

PurposeSmall breast mass (diameter≤1 cm) is prone to misdiagnosis in clinic. This paper aims to evaluate a combined application of breast imaging reporting and data system (BI-RADS) and ultrasound elastography (UE) on small breast mass (diameter≤1 cm).Materials and MethodsA retrospective analysis was carried out on 231 patients with a total of 258 small masses (the maximal diameter ≤1 cm). Ultrasound BI-RADS was used for classiifcation while UE was used to adjust the results. The results were further compared with those of postoperative pathology. The curve of ROC was employed to evaluate the combined use on small breast mass.ResultsAmong the 258 small masses, 178 (69.0%) were benign masses and the rest 80 (31.0%) were malignant. The small masses which were evaluated as BI-RADS grade 3, 4 and 5 before the operation had positive prediction value for malignant masses of 10.3% (17/165), 60.5% (46/76) and 100.0% (17/17), respectively. After adjustment with UE, the values changed to 5.3%(9/169), 75.0% (54/72) and 100.0% (17/17), respectively. After adjustment with the combination method, the area under ROC curve in BI-RADS classification was 0.904, which was signiifcantly higher than that (0.827) before the adjustment (Z=2.83,P<0.05). ConclusionFor small breast mass (diameter≤1 cm), mass of BI-RADS grade 3 has higher positive prediction value. But after adjustment with UE, the positive prediction value of mass of BI-RADS grade 3 tends to be lower, whilst that of mass of BI-RADS grade 4 increases, thus promoting the efficiency of ultrasound BI-RADS classification for small breast mass and contributing to the identiifcation of benign and malignant small breast masses.

In this article we analyzed the current development of moxibustion treating rheumatoid arthritis from the usefulness, advancement, synergistic effect as well as the variance between different kind of moxibustion. We concluded that moxibustion was an effective intervention for treating RA, and the methods used in moxibustion were searched in clinic. But the clinical tralls has a long way to go, we should pay more attention to the critical issues while in the use of moxibustion.

Objective To investigate serum alpha2-Heremans-Schmid glycoprotein ( AHSG ) level and its relationship with associated clinical parameters in subjects with simple overweight and obesity. Methods Forty-nine subjects with obesity ( OB group) , 176 subjects with overweight ( OW group) , and 327 individuals with normal weight ( NW group) were randomly enrolled. The clinical data were collected and serum levels of AHSG and adiponectin ( APN) were determined by ELISA. The associations of serum AHSG level with other clinical parameters were assessed by Pearson correlation analysis and multiple linear regressive model. Results Serum AHSG levels were higher in OW and OB groups than that in NW group[(276. 30 and 302. 10 vs 241. 60)μg/ml], being especially higher in OB group (P<0. 05 or P<0. 01). Serum AHSG level in NW group was positively associated with fasting plasma glucose, homoeostasis model assessment of insulin resistance index, C-reactive protein (CRP), triglycerides, and free fatty acids ( FFA ) , but negatively associated with age and APN. In OW and OB groups, AHSG was also positively associated with body mass index, waist hip ratio(WHR), and low density lipoprotein cholesterol(P<0. 05 or P<0. 01) except the aforementioned clinical parameters. In multiple linear regression model, AHSG was positively associated with WHR, CRP, and FFA, and was negatively associated with APN ( P<0. 05 or P<0. 01). Conclusion The raised AHSG level in overweight and obese subjects may be a risk factor for obesity-related diseases.

The association between serum fetuin A and diabetic nephropathy (DN) in patients with type 2 diabetes mellitus(T2DM) was investigated.Serum levels of fetuin-A and adiponectin were measured by ELISA and the clinical data were collected in 101 T2DM patients with normal albuminuria (NA group),87 patients with microalbuminuria (MA group),44 patients with overt albuminuria (OA group),and 130 normal control subjects (NC group).Fetuin-A levels increased progressively from NC,NA,MA,to OA groups,and there were significant differences among groups(P＜0.05 or P＜0.01).Fetuin-A level in patients was positively associated with duration of illness,urinary albumin to creatinine ratio (ACR),fasting blood glucose,2-hour postprandial blood glucose,and C-reactive protein(CRP,P＜0.05 or P＜0.01),but was negatively associated with age and adiponectin (all P＜ 0.01).Multiple stepwise regression analysis indicated that duration of diabetes,fetuin-A,CRP,and adiponectin were independent determinants for ACR (all P ＜ 0.01).Fetuin-A may be involved in the development and pathogenesis of DN by proinflammatory effects and repressing adiponectin production.

OBJECTIVETo compare the clinical efficacy on upper limb motor impairment in stroke between the interactive dynamic scalp acupuncture therapy and the traditional scalp acupuncture therapy.

METHODSThe randomized controlled trial and MINIMIZE layering randomization software were adopted. Seventy patients of upper limb with III to V grade in Brunnstrom scale after stroke were randomized into an interactive dynamic scalp acupuncture group and a traditional scalp acupuncture group, 35 cases in each one. In the interactive dynamic scalp acupuncture group, the middle 2/5 of Dingnieqianxiexian (anterior oblique line of vertex-temporal), the middle 2/5 of Dingniehouxiexian (posterior oblique line of vertex-temporal) and Dingpangerxian (lateral line 2 of vertex) on the affected side were selected as the stimulation areas. Additionally, the rehabilitation training was applied during scalp acupuncture treatment. In the traditional scalp acupuncture group, the scalp stimulation areas were same as the interactive dynamic scalp acupuncture group. But the rehabilitation training was applied separately. The rehabilitation training was applied in the morning and the scalp acupuncture was done in the afternoon. The results in Fugl-Meyer for the upper limb motor function (U-FMA), the Wolf motor function measure scale (WM- FT) and the modified Barthel index in the two groups were compared between the two groups before treatment and in 1 and 2 months of treatment, respectively.

RESULTSAfter treatment, the U-FMA score, WMFT score and the score of the modified Barthel index were all apparently improved as compared with those before treatment (all P < 0.01). The improvement in the U-FMA score after treatment in the interactive dynamic scalp acupuncture group was better than that in the traditional scalp acupuncture group (P < 0.05). For the patients of IV to V grade in Brunnstrom scale, WMFT score in 2 months of treatment and the score of Barthel index after treatment in the interactive dynamic scalp acupuncture group were improved apparently as compared with those in the traditional scalp acupuncture group (P < 0.05, P < 0.01). But, for the patients of III grade in Brunnstrom scale, WMFT score and the score of Barthel index after treatment in the interactive dynamic scalp acupuncture group were not different significantly as compared with those in the traditional scalp acupuncture group (both P > 0.05).

CONCLUSIONFor the patients of IV to V grade in Brunnstrom scale in stroke, the interactive dynamic scalp acupuncture therapy achieves the superior improvements of the upper limb motor function and the activity of daily life as compared with the traditional scalp acupuncture therapy, and the longer the treatment lasts, the more apparent the improvements are. For the patients of III grade in Brunnstrom scale, the interactive dynamic scalp acupuncture therapy achieves the similar improvement in the upper limb motor impairment as compared with the traditional scalp acupuncture therapy.
