The biologically active constituents in Gynostemma pentaphyllum are dammarane-type glycosides,called gypenosides.They are believed to be the highest contents of this herb,easy to obtain,and mainly active in anti-tumor,controlling the blood glucose,lipid-lowering,cardiovascular protection,etc.The saponins may change into sub-glucoside after hydrolysis,for the intemal acetal glucoside structure is vulnerable to acid,alkali,and enzyme degradation.Through searching the literatures in recent years,this paper summarized the chemical constituents in the hydrolyzed products of gypenosides,for providing references to discover novel and more active lead compounds.

Objective Using an in vivo adeno-associated virus(AAV)-mediated gene transfer technique,this study was designed to evaluate the protective effects of human osteoprotegerin(OPG)transgene against joint destruction in collagen induced arthritis(CIA)model.MethodsAfter CIA was established in the Sprague-Dawley rats,the experimental animals were treated with PBS or rAAV-EGFP or rAAV-hOPG (100μl/d)intra-articular injection 25 days after arthritis induction for 10 days.Paraffin-embedded joints were then analyzed histologically.The joint destruction was evaluated by Larsen Score.The protein expression of OPG,IL-1,MMP-3 was identified by enzyme-linked immunosorbent assay(ELISA).Results Suecessful trans-gene expression was confirmed by the detection of OPG by ELISA and positive fluorescence of the frozen joint section. Image analysis revealed that the expression of OPG significantly protected against joint destruction by 30% compared with the CIA group. Conclusion OPG gene transfer mediated by rAAV effectively protects against bone destruction induced by CIA model. Those data suggest that gene transferring using rAAV-OPG may be a feasible and effective therapeutic approach to treat or prevent joint destruction in inflammatory arthritis.

Objective This study was designed to investigate the expression changes of osteopro-tegerin (OPG), tartrate-resistant acid phosphatase (TRAP) and vascular endothelial growth factor (VEGF) mRNA in collagen induced arthritis(CIA) rats. Methods After CIA was induced in Sprague-Dawley rats, the experimental animals were treated with PBS or rAAV-EGFP or rAAV-hOPG (100 μl/day) intra-articular injection for 10 days. Messenger RNAs (mRNAs) were obtained from CIA synovium 40days after first immun-ization. Reverse transcriptase-polymerase chain reactions (RT-PCR) were carried out to detect the mRNA encoding OPG, TRAP, VEGF and β-actin, which acted as inner control. The genes detected clearly by RT-PCR were quantified using real-time PCR. Results The expression of all genes was confirmed by specific single bands in RT-PCR. Real-time PCR showed that the expression levels of TRAP and VEGF were increased, whereas those of OPG mRNA were decreased in CIA group compared with normal controls. The intra-articular gene transduction markedly increased the gene copies of OPG by 128.21% (P<0.01). The expression change of OPG in synovium also caused the decrease of the expression levels of TRAP and VEGF by 58.79% (P<0.01)and 17.85% (P>0.05) respectively, however, the expression change of VEGF was not statistically significant. Conclusion OPG gene mediated by rAAV can be successfully tranfered to knee joint synovium in vivo. The results of this study suggest that gene transfer using rAAV-OPG may be a feasible and effective therapeutic approach to treat or prevent joint destruction in inflammatory arthritis.

Objective:To investigate the clinical efficacy of Yiqi Yangyin decoction combined with metformin and irbesartan in treating type 2 diabetes complicated by hypertension with qi and yin deficiency syndrome. Methods:A case-control study was performed to retrospectively analyze the clinical data of 92 patients with type 2 diabetes complicated by hypertension with qi and yin deficiency syndrome. These patients received treatment at the First People's Hospital of Huzhou from February 2021 to April 2023. They were divided into two groups, with 46 patients in each group, based on different treatment methods. The control group received metformin and irbesartan, while the observation group was treated with Yiqi Yangyin decoction in addition to the treatment provided to the control group. Both groups underwent treatment for 1 month. The clinical efficacy of the two groups was evaluated, and the changes in traditional Chinese medicine symptom scores, blood glucose levels, blood pressure, and the occurrence of adverse reactions were compared between the two groups before and after treatment. Results:The total response rate of the observation group was 93.48% (43/46), which was significantly higher than that of the control group [82.61% (38/46), χ2 = 5.63, P < 0.05). After treatment, the traditional Chinese medicine symptom score for the observation group was (9.43 ± 2.11) points, which was significantly lower than that of the control group [(12.11 ± 2.32) points, t = 11.34, P < 0.001]. The fasting blood glucose, 2-hour postprandial blood glucose, and glycosylated hemoglobin levels in the observation group were (7.51 ± 1.34) mmol/L, (9.06 ± 2.11) mmol/L, and (6.23 ± 0.76)%, respectively, all of which were significantly lower than those in the control group [(8.75 ± 2.12) mmol/L, (11.15 ± 2.43) mmol/L, (7.11 ± 1.02)%, t = 4.13, 6.14, 4.01, all P < 0.05]. The systolic blood pressure in the observation group was (125.48 ± 8.14) mmHg (1 mmHg = 0.133 kPa), which was significantly lower than that in the control group [(131.32 ± 9.22) mmHg, t = 6.76, P < 0.001]. The difference in the incidence of adverse reactions between the two groups was not statistically significant ( P > 0.05). Conclusion:Yiqi Yangyin decoction combined with metformin and irbesartan is highly effective in treating type 2 diabetes complicated by hypertension with qi and yin deficiency syndrome. This combined therapy can effectively lower the traditional Chinese medicine symptom score, improve patients' blood glucose and blood pressure levels, and has a low incidence of adverse reactions.

Objective:To investigate the value of radiomics signatures based on 18F-FDG PET/CT for predicting molecular classification and Ki-67 expression of breast cancer. Methods:A total of 134 female patients ((55.4±13.3) years) who underwent 18F-FDG PET/CT examination and were diagnosed with breast cancer by pathology in the First Affiliated Hospital of Soochow University from April 2016 to May 2023 were retrospectively enrolled. LIFEx software was used to extract radiomics features and the least absolute shrinkage and selection operator (LASSO) algorithm and independent-sample t test were used to screen potentially meaningful features and calculate the radiomics score, which were considered as radiomics models. Clinical characteristics were selected by supervised logistic regression and clinical models were established. Radiomics features and clinical characteristics were incorporated to logistic regression analysis to establish combined models. ROC curves were drawn and the differences among AUCs were analyzed by Delong test. Results:Among 134 patients, 22 were with triple negative breast cancer (TNBC), 47 were human epidermal growth factor receptor 2 (HER2) over-expression type, 37 were Luminal A type and the rest 28 were Luminal B type. The expression of Ki-67 was high in 85 patients, and was low in the rest 49 patients. The AUCs (95% CI) of the combined models for predicting TNBC, HER2 overexpression type, Luminal A type and Ki-67 expression were 0.843(0.770-0.900), 0.808(0.723-0.876), 0.825(0.711-0.908) and 0.836(0.762-0.894), respectively, which were higher than those of clinical models ( z values: 1.97-3.06, all P<0.05). Conclusion:The predictive model combining radiomics signatures based on 18F-FDG PET/CT and clinical characteristics can well predict the molecular classification and Ki-67 expression level of breast cancer.
