Objective To explore the clinical effect of hip arthroscopy in the treatment of borderline developmental dysplasia of the hip(BDDH)with acetabular labrum injury.Methods A total of 32 BDDH patients with acetabular labrum injury and undergoing hip arthroscopy between December 2019 and December 2021 were analyzed retrospectively.There were 8 males and 24 females,aged 39.41±16.27 years(18～59 years)and their mean lateral acetabular central-edge angle(LCEA)was 21.25±2.96°(18°～25°).Another 32 patients with acetabular femur impingement(FAI)matching in age and undergoing hip arthroscopy during the same period were selected into the control group,which includ-ed 15 males and 17 females,aged 42.78±12.18 years(24～70 years),with their average LCEA of 32.97°±4.96°(26°～42°).Both groups received the arthroscopic glenolabial repair,head and neck ar-ea plasty and joint capsule suture.Three,six and twenty-four hours after the surgery,both groups were evaluated the clinical effect using the modified Harris hip score(mHHS),hip outcome score sports specific subscale(HOS-SSS),hip outcome score-activities of daily living(HOS-ADL)and visual analogue scale(VAS).Results The BDDH and FAI groups were followed up for(27.6±5.4)and(28.3±6.5)months,respectively.There was no significant difference in all measurements between the two groups before the operation(P>0.05).However,3,12 and 24 months after surgery,the aver-age mHHS,HOS-SSS and HOS-ADL scores of both groups increased significantly,while the average VAS scores decreased significantly(P<0.001).Moreover,the average mHHS scores of BDDH group were significantly lower than FAI group 3,12 and 24 months after surgery(P<0.05).However,3 months after surgery,the average HOS-SSS and HOS-ADL scores in BDDH group were significantly lower than FAI group(P<0.05).None of the patients underwent re-surgery due to recurrence of symp-toms during the follow-up period.Conclusion Hip arthroscopy can achieve satisfying short-term out-comes in treating BDDH.

Phyllanthi Fructus is a highly unique medicine and food homologous item, which exhibits distinctive flavor, notable nutritional value, and abundant pharmacological activity. It has enormous potential in the creation of health products and pharmaceuticals. However, due to the unique laws of quality formation and transfer of Phyllanthi Fructus, its appearance, shape, chemical compositions, nutrients, and sensory flavors are frequently greatly influenced by botanical resources, the processing and storage conditions. As a result, the current quality evaluation model is difficult to meet the needs of Phyllanthi Fructus as a medicine and food homologous item in the development of diversified products. This paper constructs the hierarchical utilization mode of Phyllanthi Fructus based on its unique quality formation and transmission laws, explores the quality evaluation model for food-oriented use and medicinal-oriented use, respectively, and systematically describes the quality evaluation idea under diversified application scenarios. This paper aims to serve as a reference for the construction of a quality evaluation model suitable for the medicine and food homologous item of Phyllanthi Fructus.

【Objective】 To investigate the protection of astragaloside IV from high glucose induced podocyte injury and mitochondrial dysfunction and its molecular mechanisms. 【Methods】 The model of podocyte injury induced by high glucose (30 mmol/L glucose) was established, and the model cells were treated with low, medium and high doses of astragaloside IV respectively; cell activity was detected by CCK-8. Apoptosis was detected by TUNEL staining. Mitochondrial membrane potential was detected by JC-1 fluorescence probe. ATP content was detected by the kit. The expression levels of apoptosis and podocyte injury related proteins and Notch pathway related proteins were detected by Western blotting. 【Results】 Compared with the control group, cell activity was decreased, apoptosis level was increased (P<0.05), anti-apoptotic protein (Bcl2) expression was decreased, and apoptosis protein (Bax, cleaved-caspase 9, cleaved-caspase 3) expressions were increased (all P<0.05) in HG group. Compared with HG group, HG+AS-IV improved cell activity and apoptosis level induced by high glucose (P<0.05), increased expression of anti-apoptotic protein (Bcl2), and decreased expressions of apoptotic protein (Bax, cleaved-caspase 9, and cleaved-caspase 3) (all P<0.05). Compared with the control group, mitochondrial dysfunction occurred in HG group, JC-1 monomer content increased, and ATP content decreased (all P<0.05). Compared with HG group, HG+AS-IV improved mitochondrial dysfunction, increased JC-1 polymer content and ATP content (P<0.05). In addition, compared with the control group, the expression of Notch pathway-related protein was decreased in HG group (P<0.05). Compared with HG group, Notch pathway-related protein expression was increased in HG+AS-IV group (all P<0.05). Molecular docking results showed that AS-IV could bind Notch1. 【Conclusion】 Astragaloside IV can improve podocyte injury and mitochondrial dysfunction induced by high glucose, possibly by inhibiting Notch pathway activation.

Dioscoreae Rhizoma formula granules are made from decoction pieces by decocting， extracting， separating， concentrating， drying and granulating， which have the advantages of simple dispensing， convenient use and easy to take without decoction. However， because Dioscoreae Rhizoma is rich in starch and mucus components， its extract powder and formula granules are poorly soluble and difficult to dissolve or disperse completely within 5 min， and the insoluble material is difficult to dissolve completely even after 24 h in water， which affects the quality evaluation of the formula granules and medication psychology of patients. Therefore， by studying the dissolution process and mechanism of Dioscoreae Rhizoma extract and its formula granules， it was found that the special chemical composition of Dioscoreae Rhizoma， the denaturation of starch and its compounding with protein and other substances during the high temperature extraction process， and the contraction of coating membrane during the spray drying process were combined to form the special microstructure of coating membrane covering starch granules， and it is the root cause of poor solubility of Dioscoreae Rhizoma formula granules. Based on the research on the structure， property and function of the powder， this paper proposed a technical strategy to improve the solubility of Dioscoreae Rhizoma formula granules by powder modification process， and experimentally demonstrated that the modified Dioscoreae Rhizoma formula granules could completely dissolve within 2 min， which solved the technical problem and could provide reference for the improvement of solubility of other similar varieties， and promote the high-quality development of traditional Chinese medicine formula granule industry.

Heart failure (HF) is a global public health problem with high morbidity and mortality. A large number of studies have shown that HF is caused by severe energy metabolism disorders, which result in an insufficient heart energy supply. This deficiency causes cardiac pump dysfunction and systemic energy metabolism failure, which determine the development of HF and recovery of heart. Current HF therapy acts by reducing heart rate and cardiac preload and afterload, treating the HF symptomatically or delaying development of the disease. Drugs aimed at cardiac energy metabolism have not yet been developed. In this review, we outline the main characteristics of cardiac energy metabolism in healthy hearts, changes in metabolism during HF, and related pathways and targets of energy metabolism. Finally, we discuss drugs that improve cardiac function

Traditional Chinese herbs (TCH) are currently gaining attention in disease prevention and health care plans. However, their general bitter taste hinders their use. Despite the development of a variety of taste evaluation methods, it is still a major challenge to establish a quantitative detection technique that is objective, authentic and sensitive. Based on the two-bottle preference test (TBP), we proposed a novel quantitative strategy using a standardized animal test and a unified quantitative benchmark. To reduce the difference of results, the methodology of TBP was optimized. The relationship between the concentration of quinine and animal preference index (PI) was obtained. Then the PI of TCH was measured through TBP, and bitterness results were converted into a unified numerical system using the relationship of concentration and PI. To verify the authenticity and sensitivity of quantified results, human sensory testing and electronic tongue testing were applied. The quantified results showed a good discrimination ability. For example, the bitterness of Coptidis Rhizoma was equal to 0.0579 mg/mL quinine, and Nelumbinis Folium was equal to 0.0001 mg/mL. The validation results proved that the new assessment method for TCH was objective and reliable. In conclusion, this study provides an option for the quantification of bitterness and the evaluation of taste masking effects.

Objective:To analyze the efficacy and the adverse reactions of conventional treatment-failed advanced refractory ovarian cancer cases after treatment with apatinib.Methods:Six patients enrolled in the Second Hospital of Tianjin Medical University from June 2015 to October 2015 received treatment with apatinib. Treatment efficacy was evaluated by imaging and analysis of tumor markers,including CA125,CEA,and NSE.Results:The age range of the six patients was 48-71 years(median:55 years).Their histopath-ological subtypes included poorly differentiated serous cystadenocarcinoma(4/6),borderline papillary adenoma(1/6),and clear cell carcinoma(1/6).Clinical evaluation of patients revealed no cases with complete remission,two cases with partial response,one case with stable disease,and three cases with progressive disease.The objective response rate was 33%(2/6)and the disease control rate was 50%(3/6).In all patients,the main side effects were hypertension and hand-foot syndrome,which were controlled.Conclusions:The treatment of conventional treatment-failed advanced refractory ovarian cancer with apatinib has better exact effects,and medical toxicity can be controlled.In the future,to seek more effective treatment strategies,the mechanism of apatinib in the treatment of ad-vanced ovarian cancer should be further explored.

Objective To study the relationship between the expression level of PLK1 in castration-resistant prostate cancer (CRPC) tissues, and its relationship with pathological features. Methods Forty-four CRPC specimens including 28 samples from patients with prostate adenocarcinoma, 14 samples from patients with neuroendocrine prostate cancer (NEPC) and 2 samples from patients with other types of prostate cancer, and 10 normal prostatic hyperplasia specimens were collected from January 2010 to September 2016 in the Second Hospital of Tianjin Medical University. The expression levels of PLK1 in these tissues were detected by S-P immunohistochemistry. The relationship between PLK1 expression and pathologic factors was discussed. Results The positive expression of PLK1 was located in cytoplasm of carcinoma cells, and no express of PLK1 was found in benign prostatic hyperplasia tissues. The expression levels of PLK1 showed no significantly differences between different groups of age, local tumor invasion and regional nodal status, and the level of prostate-specific antigen (PSA, P>0.05). The expression level of PLK1 in patients with Gleason score>8 was higher than that in patients with Gleason score≤8. The PLK1 expression level was positively correlated with Gleason score (rs=0.441,P<0.05). Conclusion PLK1 protein is over-expressed in CRPC tissues, which can reflect the proliferation and differentiation of cancer cells and may be a potential marker of CRPC.
