Objective To observe the morphology changes in articular cartilage of knee osteoarthritis ( KOA) model rats after intervention with Shudi Jisheng Zhuanggu Decoction (SJZD). Methods SD rats were randomized into 7 groups, namely blank control group, model group, Paracetamol group ( 0.270 g/kg) , Zhuangu Guanjie Pills group ( 1.08 g/kg) , and high-, middle- and low-dosage SJZD groups ( 27.450, 13.725, 6.863 g/kg, respectively). Rats were injected with papain solution into the right knee joint to build models of KOA before administration of drugs. Thickness of right knee joint was measured to evaluate the effect of SJZD on the swelling degree of knee joint. Histological changes of knee cartilage were evaluated by Mankin scoring method after the cartilage sections being stained with hematoxylin-eosin (HE). Results Swelling degree of knee joint and Mankin scores were significantly increased in the model group compared to the blank control group ( P<0.01). In comparison with the model group, the swelling degree of knee joint and Mankin scores of SJZD groups were significantly decreased (P<0.05 or P<0.01), and the pathological changes were relieved. Conclusion SJZD can ameliorate the pathological changes of knee articular cartilage in rats with KOA, so as to delay cartilage degeneration and protect the cartilage.

Objective To observe the epidemiology characterization of Borna disease virus (BDV) in animal brain in Ili, Xinjiang, and to find out the potential infection of the Borna disease virus to prevent its outbreak. Methods The BDV p24 gene of animal brain tissues in Ili including 200 horses, 75 donkeys and 100 shepherd dogs was detected by fluorescence quantitative nest reverse transcriptase polymer-ase chain reaction(FQ-nRT-PCR). GFP-p24,pMD-19 plasmid contamination was excluded from positive products. Clone sequencing was used to analyze the homology of gene and amino acid sequence. Results BDV p24 gent was found in 3 Ili horses, 4 Ili donkeys and 9 shepherd dogs, and the positive ratio is 1.5%, 5.3% and 9.0%, respectively. The GFP-p24,pMD-19 were not found in BDV p40 gene and plasmid stand-ard. The sequence of BDV p24 amplification production was totally the same as He/80 virus strain. Conclu-sion Natural infection of BDV may exist in the animals(horses, donkeys and dogs)in Ili, and the epidem-ic strain of BDV in this area was homological as He/80 virus strain.

Objective To observe the clinical efficacy of Jiajian Yijing Decoction on improving clinical symptoms and pregnancy rate of patients with diminished ovarian reserve(DOR)and kidney deficiency and hepat-ic depression syndrome. Methods Patients with DOR and kidney deficiency and hepatic depression syndrome were randomly divided into traditional Chinese medicine group(n = 33)and western medicine group(n = 34). Patients in TCM group were treated with Jiajian Yijing Decoction and those in western medicine group with artificial periodic therapy(Progynova 2 mg/d+Dydrogesterone 20 mg/d).All cases were treated with 3 menstrual cycles.The improvement of clinical symptoms of DOR and kidney deficiency and hepatic depression syndrome and pregnancy rate were observed. Results The improvement of clinical symptoms of DOR and kidney deficiency and hepatic depression syndrome after treatment in TCM group was more obvious than that in western medicine group(P<0.05 or P < 0.01). The pregnancy rate after treatment in TCM group was higher than that in western medicine group, but it had no statistic difference(P>0.05).Conclusions Jiajian Yijing Decoction can obviously improve the clin-ical symptoms of patients with DOR and kidney deficiency and hepatic depression syndrome and increase the preg-nancy rate in infertile patients.It is worthy of clinical popularization.

Objective:
To evaluate the efficacy of a self-developed mobile augmented reality navigation system (MARNS) in guiding spinal level positioning during intraspinal tumor surgery based on a dual-error theory.
Methods:
This retrospective study enrolled patients diagnosed with intraspinal tumors admitted to Fujian Provincial Hospital between May and November 2023. The participants were divided into conventional x-rays and self-developed MARNS groups according to the localization methods they received. Position time, length of intraoperative incision variation, and location accuracy were systematically compared.
Results:
A total of 41 patients (19 males) with intraspinal tumors were included, and MARNS was applied to 21 patients. MARNS achieved successful lesion localization in all patients with an error of 0.38±0.12 cm. Compared to x-rays, MARNS significantly reduced positioning time (129.00±13.03 seconds vs. 365.00±60.43 seconds, p<0.001) and length of intraoperative incision variation (0.14 cm vs. 0.67 cm, p=0.009).
Conclusion
The self-developed MARNS, based on augmented reality technology for lesion visualization and perpendicular projection, offers a radiation-free complement to conventional x-rays.

The lifting wavelet is used to decompose the original ECG signals and separate them into the approach signals with low frequency and the detail signals with high frequency, based on frequency characteristic. Parts of the detail signals are ignored according to the frequency characteristic. To avoid the distortion of QRS Complexes, the approach signals are filtered by an adaptive smooth filter with a proper threshold value. Through the inverse transform of the lifting wavelet, the reserved approach signals are reconstructed, and the three primary kinds of noise are limited effectively. In addition, the method is fast and there is no time delay between input and output.
