ObjectiveTo study the effect on quality of life and the bone turnover markers of Buzhong Yiqitang in the treatment of senile osteoporotic vertebral compression fracture (OVCF, syndrome of Qi deficiency in spleen and stomach) after operation based on ''spleen governing muscle''. MethodA total of 135 senile patients with OVCF treated by percutaneous kyphoplasty in Rizhao Hospital of Traditional Chinese Medicine from January 2020 to January 2021 were enrolled in this study. They were randomly assigned to two groups on the basis of block randomization at a ratio of 2∶1 (90 cases in the observation group and 45 cases in the control group). Both groups were administrated with calcitriol capsules (0.5 μg·d-1) and caltrate D (1 200 mg·d-1) for basic treatment of osteoporosis. The observation group was additionally treated with Buzhong Yiqitang. Bone mineral density (BMD), procollagen type Ⅰ N-terminal propeptide (PINP), osteocalcin (OST), β cross-linked C-telopeptide of type 1 collagen (β-CTx), appendicular skeletal muscle mass index (ASMI), and quadriceps muscle strength were compared between the two groups before and 6, 12 months after treatment. Additionally, traditional Chinese medicine (TCM) symptom score and visual analogue score (VAS) before and 3, 6 months after treatment, as well as quality of life questionnaire of the European Foundation for osteoporosis (QUALEFFO) score before and 3, 6, 12 months after treatment, were compared between the two groups. ResultA total of 85 patients in the observation group and 41 patients in the control group were followed up. The general curative effect of the observation group was better than that of the control group (χ2=10.503, P<0.05). Specifically, the observation group had higher PINP, BMD, ASMI, and quadriceps muscle strength but lower β-CTx, TCM symptom score, VAS, and QUALEFFO score than the control group (P<0.05, P<0.01). No adverse reactions related to Buzhong Yiqitang were observed. ConclusionBuzhong Yiqitang can regulate bone metabolism indexes, promote osteogenesis, increase bone density, enhance skeleton appendiculare and quadriceps muscle strength, relieve clinical symptoms, and improve quality of life in patients with senile OVCF (syndrome of Qi deficiency in spleen and stomach), being worthy of promotion in clinical application.

The α-amino acid ester acyltransferase (SAET) from Sphingobacterium siyangensis is one of the enzymes with the highest catalytic ability for the biosynthesis of l-alanyl-l-glutamine (Ala-Gln) with unprotected l-alanine methylester and l-glutamine. To improve the catalytic performance of SAET, a one-step method was used to rapidly prepare the immobilized cells (SAET@ZIF-8) in the aqueous system. The engineered Escherichia coli (E. coli) expressing SAET was encapsulated into the imidazole framework structure of metal organic zeolite (ZIF-8). Subsequently, the obtained SAET@ZIF-8 was characterized, and the catalytic activity, reusability and storage stability were also investigated. Results showed that the morphology of the prepared SAET@ZIF-8 nanoparticles was basically the same as that of the standard ZIF-8 materials reported in literature, and the introduction of cells did not significantly change the morphology of ZIF-8. After repeated use for 7 times, SAET@ZIF-8 could still retain 67% of the initial catalytic activity. Maintained at room temperature for 4 days, 50% of the original catalytic activity of SAET@ZIF-8 could be retained, indicating that SAET@ZIF-8 has good stability for reuse and storage. When used in the biosynthesis of Ala-Gln, the final concentration of Ala-Gln reached 62.83 mmol/L (13.65 g/L) after 30 min, the yield reached 0.455 g/(L·min), and the conversion rate relative to glutamine was 62.83%. All these results suggested that the preparation of SAET@ZIF-8 is an efficient strategy for the biosynthesis of Ala-Gln.

Objective:To evaluate the clinical value of 18F-FDG PET/CT findings in patients with T1-2 lung adenocarcinoma spread through air spaces (STAS). Methods:From June 2018 to June 2020, a total of 80 patients (36 males, 44 females; age: 19-84 (59.9±11.8) years) with surgically and pathologically confirmed T1-2 lung adenocarcinomas in Jiangmen Central Hospital were enrolled retrospectively. All patients underwent 18F-FDG PET/CT examination preoperatively and were divided into STAS positive and negative groups according to the histopathological diagnosis. Independent-sample t test, Mann-Whitney U test, χ2 test and Fisher exact test were used to analyze differences of gender, age, tumor biomarker, SUV max, SUV mean, features showed on high resolution CT (HRCT; including diameter, lesion location, morphology, density, lobulated sharp, spiculated sign, vacuole sign, air bronchgram sign, pleural traction and para-emphysema), and pathologic findings (micropapillary pattern, lymphvascular inversion, pleural inversion and lymph node metastasis) between the two groups, and then multivariate logistic regression was performed. The ROC curve was employed to evaluate the predictive value of parameters for STAS of T1-2 lung adenocarcinomas. Results:Among the 80 patients with T1-2 lung adenocarcinomas, 12 (15.0%) were STAS positive and 68 (85.0%) were STAS negative. Significant differences were shown in SUV max, SUV mean, micropapillary pattern, lymphvascular inversion and lymph node metastasis between the two groups ( z values: -2.60, -2.17; χ2 values: 29.56, 9.28, 17.40, P<0.001 or P<0.05). SUV max (odds ratio ( OR): 1.348 (95% CI: 1.071-1.695), P=0.011), micropapillary pattern ( OR=47.444 (95% CI: 4.592-490.214), P=0.001) and lymph node metastasis ( OR=8.201 (95% CI: 1.129-59.576), P=0.038) were independent risk factors for STAS positive in multivariation logistic regression analysis. The optimum cut-off value for SUV max was 3.85 in the ROC analysis with the AUC of 0.737 (95% CI: 0.614-0.859), the sensitivity of 11/12, the specificity of 55.9%(38/68) and the accuracy of 61.2%(49/80). The AUC of the SUV max combined with micropapillary pattern and lymph node metastasis was 0.945 (95% CI: 0.892-0.999) with the sensitivity of 11/12, the specificity of 88.2%(60/68) and the accuracy of 88.7%(71/80). Conclusions:The PET/CT characteristics may be useful in differentiating STAS status among patients with T1-2 lung adenocarcinoma. SUV max >3.85, pathological papillary pattern and lymph node metastasis are independent risk factors to predict STAS.
