随着大数据的发展以及数据安全相关法规的出台，人们的隐私保护意识逐渐加强，“数据孤岛”现象愈发严重。联邦学习技术作为解决该问题的有效方法之一，已成为当下备受关注的热点。在纵向联邦学习在线推理过程中，当前的主流方法并未考虑对数据标识的保护。针对此问题，提出一种适用于纵向联邦线性模型在线推理过程中的成员推断攻击的隐私保护方法，通过构造具有假阳率的过滤器来避免对数据标识的精确定位，从而保证数据的安全性；使用同态加密实现在线推理过程的全密态，保护中间计算结果；根据同态加密的密文倍乘性质，使用随机数乘法盲化操作，保证最终推理结果的安全性。该方案进一步提高了纵向联邦学习在线推理过程中用户隐私的安全性，且具有更低的计算开销和通信开销。

Objective To investigate the effect of electroacupuncture on articular cartilage and subchon- dral polarization - related protein expression in aged rats. Methods Sixteen 24-month -old SD male rats were randomly divided into old group and electroacupuncture group, with 8 rats in each group. Eight SD male rats aged 6 months were youth group. Electroacupuncture group received electroacupuncture treatment, and the two sides of the“Taixi”, “Zusanli”, “Yanglingquan”, “xuehai”were selected. Electroacupuncture parameters：density wave, sparse wave frequency 3 Hz, dense wave 15 Hz, current intensity 1 mA, once a day, 30 minutes each time, 5 daysa week, consecutive 8 weeks. The other two groups fixed sterile needles with adhesive tape, connected the elec- troacupuncture instrument but did not turn on. After 8 weeks, the content of C-terminal peptide（CTX-Ⅱ) in serum of type Ⅱ collagen was determined by ELISA. Microscopic CT（Micro-CT) was used to detect the microstruc- ture of the left tibia subchondral bone. The left tibial plateau cartilage was observed under light microscope with saffron-solid green staining, and the degree of articular cartilage degeneration was evaluated by modified Mankin′s score. RT-qPCR and Westernblot were used to detect matrix metalloproteinase 1（MMP-1), matrix metallopro- teinase 3（MMP-3), matrix metalloproteinase 13（MMP-13), tumor necrosis factor α（TNF-α), interleukin 1β （IL-1β), and macrophage mannose-receptor（MMR). Expression levels of arginase 1（Arg1) mRNA and protein. Results （1) Compared with the young group, the CTX-Ⅱin the blood of the old group increased（P < 0.05), Saf- fron O-fast green staining showed that the structure of rat cartilage was seriously damaged, cartilage and subchon- dral bone decomposed indistinctly, calcification was severe, multiple tidal lines appeared, the number of cells decreased significantly, split layer appeared, cell morphology and structure was abnormal, and staining was uneven. and the modified Mankin′s score increased（P < 0.05). Bone mineral density, bone volume fraction and number of bone trabeculae decreased（P < 0.05), trabecular thickness and trabecular spacing increased（P < 0.05), MMP1, MMP3, MMP13 mRNA and protein expression increased（P < 0.05), TNF-α, IL-1 β mRNA and protein expres- sion increased（P < 0.05), MMR, Arg1mRNA and protein decreased（P < 0.05). （2) Compared with the senile group, the CTX-Ⅱdecreased in the electroacupuncture group（P < 0.05), The saffron O-fast green staining showed that the cartilage of the rats was slightly smooth and there was no obvious cleavage layer. The number of chondro- cytes in the aged group was higher than that in the aged group, and the staining was more uniform；and the modi- fied Mankin′s score was decreased（P < 0.05). Bone mineral density, bone volume fraction and trabecular number increased（P < 0.05), trabecular spacing decreased（P < 0.05), trabecular thickness tended to decrease（P > 0.05), MMP1, MMP3, MMP13mRNA and protein expression decreased（P < 0.05), TNF-α, IL-1 β mRNA and protein expression decreased（P < 0.05), MMR, Arg1mRNA and protein increased（P < 0.05). Conclusion Electroacupuncture may protect joints by promoting OA articular cartilage and subchondral bone M2 polarization, alleviating articular cartilage degradation and inhibiting subchondral bone osteoporosis in aged rats.

To explore the effects of modified biochar on seed germination and seedling growth of sudangrass under crude oil stress, cotton straw biochar modified by nitric acid and Fenton reagent was added to the contaminated soil with 4% oil content. The effects of the two kinds of modified biochar on germination rate, germ length, radicle length, biomass, and total petroleum hydrocarbon degradation rate of sudangrass were studied by soil culture germination test. The results showed that both biochar and modified biochar significantly increased soil organic matter content（P<0.05）. The addition of unmodified biochar increased soil pH, while the addition of biochar modified by nitric acid and Fenton reagent decreased soil pH. Compared with the treatment without biochar, the addition of biochar significantly increased the germination rate, germ length, and plant biomass accumulation of sudangrass. Modified biochar promoted seed growth. The germ length and biomass in treatments with 4% biochar modified with nitric acid increased by 67.83% and 80.26%, respectively, compared with the control group. The addition of biochar and modified biochar could significantly improve the degradation rate of total petroleum hydrocarbons in soil. Compared with the treatment without biochar, the degradation rate of total petroleum hydrocarbons in treatments with 4% biochar and 4% Fenton-modified biochar increased by 23.86 and 20.89 percentage points, respectively. Therefore, under crude oil stress, the addition of modified biochar mitigates the negative effects of crude oil pollution on seed germination of sudangrass. The modification method and the amount of added biochar will affect the short-term degradation effect of petroleum hydrocarbons in soil under the joint action of sudangrass and biochar.
