Study on release and antioxidant activity of quercetin after loaded by hot alkali hydrolysis modified UiO-66 material / 药学学报

UiO-66 (University of Oslo 66) is a kind of promising material that can improve the release and bioavailability of poorly water-soluble bioactive compounds of traditional Chinese medicine. However, the loading of quercetin in raw UiO-66 was not ideal. In this study, UiO-66-BH (UiO-66-blend-heating) was obtained by heating UiO-66 and KOH solution following blended them. UiO-66-BH maintained the outline of octahedral structure of UiO-66 but with obvious rough and uneven pores on the surface. UiO-66-BH had good adsorption of quercetin with saturation adsorption was 138.92 mg·g-1, the adsorption process belonged to single molecular layer adsorption and was controlled by chemisorption. UiO-66-BH can control the release of quercetin in simulated gastrointestinal fluid, and the drug concentration was significantly higher than that of free quercetin after long-term release (36% vs 9%). Compared with quercetin, the ABTS (2,2′-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) ammonium salt) radical scavenging activity of UiO-66-BH@quercetin drug delivery system decreased, while the DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging activity remained almost unchanged. The drug delivery system showed a strong antioxidant effect similar to quercetin. The findings indicated that UiO-66-BH could control release of quercetin and was expected to be used as a drug carrier material for some insoluble active components of traditional Chinese medicine such as quercetin.

Construction and evaluation of a nomogram for predicting the prognosis of patients with colorectal cancer with peritoneal carcinomatosis treated with cytoreductive surgery plus hyperthermic intraperitoneal chemotherapy / 中华胃肠外科杂志

Objectives: To construct a nomogram incorporating important prognostic factors for predicting the overall survival of patients with colorectal cancer with peritoneal metastases treated with cytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC), the aim being to accurately predict such patients' survival rates. Methods: This was a retrospective observational study. Relevant clinical and follow-up data of patients with colorectal cancer with peritoneal metastases treated by CRS + HIPEC in the Department of Peritoneal Cancer Surgery, Beijing Shijitan Hospital, Capital Medical University from 2007 January to 2020 December were collected and subjected to Cox proportional regression analysis. All included patients had been diagnosed with peritoneal metastases from colorectal cancer and had no detectable distant metastases to other sites. Patients who had undergone emergency surgery because of obstruction or bleeding, or had other malignant diseases, or could not tolerate treatment because of severe comorbidities of the heart, lungs, liver or kidneys, or had been lost to follow-up, were excluded. Factors studied included: (1) basic clinicopathological characteristics; (2) details of CRS+HIPEC procedures; (3) overall survival rates; and (4) independent factors that influenced overall survival; the aim being to identify independent prognostic factors and use them to construct and validate a nomogram. The evaluation criteria used in this study were as follows. (1) Karnofsky Performance Scale (KPS) scores were used to quantitatively assess the quality of life of the study patients. The lower the score, the worse the patient's condition. (2) A peritoneal cancer index (PCI) was calculated by dividing the abdominal cavity into 13 regions, the highest score for each region being three points. The lower the score, the greater is the value of treatment. (3) Completeness of cytoreduction score (CC), where CC-0 and CC-1 denote complete eradication of tumor cells and CC-2 and CC-3 incomplete reduction of tumor cells. (4) To validate and evaluate the nomogram model, the internal validation cohort was bootstrapped 1000 times from the original data. The accuracy of prediction of the nomogram was evaluated with the consistency coefficient (C-index), and a C-index of 0.70-0.90 suggest that prediction by the model was accurate. Calibration curves were constructed to assess the conformity of predictions: the closer the predicted risk to the standard curve, the better the conformity. Results: The study cohort comprised 240 patients with peritoneal metastases from colorectal cancer who had undergone CRS+HIPEC. There were 104 women and 136 men of median age 52 years (10-79 years) and with a median preoperative KPS score of 90 points. There were 116 patients (48.3%) with PCI≤20 and 124 (51.7%) with PCI>20. Preoperative tumor markers were abnormal in 175 patients (72.9%) and normal in 38 (15.8%). HIPEC lasted 30 minutes in seven patients (2.9%), 60 minutes in 190 (79.2%), 90 minutes in 37 (15.4%), and 120 minutes in six (2.5%). There were 142 patients (59.2%) with CC scores 0-1 and 98 (40.8%) with CC scores 2-3. The incidence of Grade III to V adverse events was 21.7% (52/240). The median follow-up time is 15.3 (0.4-128.7) months. The median overall survival was 18.7 months, and the 1-, 3- and 5-year overall survival rates were 65.8%, 37.2% and 25.7%, respectively. Multivariate analysis showed that KPS score, preoperative tumor markers, CC score, and duration of HIPEC were independent prognostic factors. In the nomogram constructed with the above four variables, the predicted and actual values in the calibration curves for 1, 2 and 3-year survival rates were in good agreement, the C-index being 0.70 (95% CI: 0.65-0.75). Conclusions: Our nomogram, which was constructed with KPS score, preoperative tumor markers, CC score, and duration of HIPEC, accurately predicts the survival probability of patients with peritoneal metastases from colorectal cancer treated with cytoreductive surgery plus hyperthermic intraperitoneal chemotherapy.

Analysis of Chinese Medical Syndrome Features of Ischemic Stroke Based on Similarity of Symptoms Subgroup / 中国结合医学杂志

OBJECTIVE@#To derive the Chinese medicine (CM) syndrome classification and subgroup syndrome characteristics of ischemic stroke patients.@*METHODS@#By extracting the CM clinical electronic medical records (EMRs) of 7,170 hospitalized patients with ischemic stroke from 2016 to 2018 at Weifang Hospital of Traditional Chinese Medicine, Shandong Province, China, a patient similarity network (PSN) was constructed based on the symptomatic phenotype of the patients. Thereafter the efficient community detection method BGLL was used to identify subgroups of patients. Finally, subgroups with a large number of cases were selected to analyze the specific manifestations of clinical symptoms and CM syndromes in each subgroup.@*RESULTS@#Seven main subgroups of patients with specific symptom characteristics were identified, including M3, M2, M1, M5, M0, M29 and M4. M3 and M0 subgroups had prominent posterior circulatory symptoms, while M3 was associated with autonomic disorders, and M4 manifested as anxiety; M2 and M4 had motor and motor coordination disorders; M1 had sensory disorders; M5 had more obvious lung infections; M29 had a disorder of consciousness. The specificity of CM syndromes of each subgroup was as follows. M3, M2, M1, M0, M29 and M4 all had the same syndrome as wind phlegm pattern; M3 and M0 both showed hyperactivity of Gan (Liver) yang pattern; M2 and M29 had similar syndromes, which corresponded to intertwined phlegm and blood stasis pattern and phlegm-stasis obstructing meridians pattern, respectively. The manifestations of CM syndromes often appeared in a combination of 2 or more syndrome elements. The most common combination of these 7 subgroups was wind-phlegm. The 7 subgroups of CM syndrome elements were specifically manifested as pathogenic wind, pathogenic phlegm, and deficiency pathogens.@*CONCLUSIONS@#There were 7 main symptom similarity-based subgroups in ischemic stroke patients, and their specific characteristics were obvious. The main syndromes were wind phlegm pattern and hyperactivity of Gan yang pattern.

Ventromedial Thalamus-Projecting DCN Neurons Modulate Associative Sensorimotor Responses in Mice / 神经科学通报·英文版

The deep cerebellar nuclei (DCN) integrate various inputs to the cerebellum and form the final cerebellar outputs critical for associative sensorimotor learning. However, the functional relevance of distinct neuronal subpopulations within the DCN remains poorly understood. Here, we examined a subpopulation of mouse DCN neurons whose axons specifically project to the ventromedial (Vm) thalamus (DCNVm neurons), and found that these neurons represent a specific subset of DCN units whose activity varies with trace eyeblink conditioning (tEBC), a classical associative sensorimotor learning task. Upon conditioning, the activity of DCNVm neurons signaled the performance of conditioned eyeblink responses (CRs). Optogenetic activation and inhibition of the DCNVm neurons in well-trained mice amplified and diminished the CRs, respectively. Chemogenetic manipulation of the DCNVm neurons had no effects on non-associative motor coordination. Furthermore, optogenetic activation of the DCNVm neurons caused rapid elevated firing activity in the cingulate cortex, a brain area critical for bridging the time gap between sensory stimuli and motor execution during tEBC. Together, our data highlights DCNVm neurons' function and delineates their kinematic parameters that modulate the strength of associative sensorimotor responses.

Molecular Mechanism of Shengxiantang in Treating Myasthenia Gravis： Based on Network Pharmacology and Molecular Docking / 中国实验方剂学杂志

ObjectiveTo predict the pharmacodynamic basis and core target of Shengxiantang in the treatment of myasthenia gravis （MG） by network pharmacology and molecular docking and to further verify the molecular mechanism through animal experiment. MethodThe active components and potential targets of Shengxiantang were retrieved from Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP）， and the disease-related targets from GeneCards and other databases. Then the common targets of the decoction and the disease were screened out， followed by the construction of protein-protein interaction （PPI） network， and Gene Ontology （GO） term enrichment and Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment of the common targets based on STRING database and Cytoscape 3.8.2. Afterward， Cytoscape 3.8.2 was employed to construct the disease-active component-target network. AutoDock and PyMOL were used for molecular docking of key components and hub genes. Finally， we used the Rα97-116 peptide to induce experimental autoimmune myasthenia gravis （EAMG） in rats and then verified the core target yielded in the docking with the model rats. ResultA total of 655 disease-related targets， 118 active components of the decoction， 21 common targets of the disease and the decoction， and 3 hub genes were screened out. The common targets were mainly involved in the GO terms of regulation of active oxygen metabolism， positive regulation of protein transport， and positive regulation of protein localization， and the KEGG pathways of toll-like receptor signaling pathway， phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt） signaling pathway， hypoxia inducible factor-1 （HIF-1） signaling pathway， and T cell receptor signaling pathway. The results of molecular docking showed that quercetin and Akt1 had the lowest and stable binding energy and interacted with each other through the amino acid residue LYS-30. Western blot demonstrated that Shengxiantang significantly inhibited the expression of p-Akt protein in the spleen of EAMG rats. ConclusionThe pharmacological mechanism of Shengxiantang in the treatment of MG may be that the main chemical components regulate the expression of the core protein Akt， and then may participate in and affect PI3K/Akt signaling pathways， laying a theoretical and experimental basis for further research.

Effect of different parts of Pinelliae Rhizoma Decoction against airway inflammation and analysis of effective components / 中国中药杂志

This study investigated the material basis and mechanism of Pinelliae Rhizoma Decoction in the treatment of airway inflammation. The cigarette smoke combined with lipopolysaccharide(LPS) was used to induce an airway inflammation model in mice. The expression levels of IL-6 and IL-8 in the bronchoalveolar lavage fluid(BALF) and the phosphorylation levels of p38 and IκB in the lungs of mice were taken as indexes to screen the effective extracts by system solvent extraction from Pinelliae Rhizoma Decoction(dichloromethane extract, ethyl acetate extract, n-butanol extract, etc.). Meanwhile, the human bronchial epithelial(16-HBE) cell model of cigarette smoke extract(CSE)-induced injury was established, and the mRNA expression levels of IL-6 and IL-8 and the phosphorylation levels of p38 and IκB proteins were also taken as indexes to evaluate the anti-inflammatory effect of different extracts of Pinelliae Rhizoma Decoction. The results showed that Pinelliae Rhizoma Decoction significantly antagonized airway inflammation in mice by down-regulating the expression levels of IL-6 and IL-8 in mice with airway inflammation and 16-HBE cells with CSE-induced injury and inhibiting the phosphorylation levels of p38 and IκB. The dichloromethane and ethyl acetate extracts of Pinelliae Rhizoma Decoction showed significant anti-inflammatory effects, while such effects of other extracts were not prominent. Furthermore, the database of Pinelliae Rhizoma composition was constructed, and the components in effective extracts were analyzed by HPLC-TOF-MS and Nano-LC-MS/MS. As revealed by the results, the compositions of the two effective extracts were similar with 36 common components. They were combined and then divided into Pinelliae Rhizoma alkaloids(PTAs) and Pinelliae Rhizoma non-alkaloids(PTNAs) by 732 cation-exchange resin. Further in vitro investigation confirmed the significant anti-inflammatory effect of PTNAs, while such effect of PTAs was not manifest. The MS analysis showed 172 peptides and 7 organic acids in PTNAs. The peptide content in PTNAs was 63.5% measured by quantitative analysis of BCA assay, and the organic acid content was 9.92% by potentiometric titration method. The findings of this study suggested that Pinelliae Rhizoma Decoction could antagonize airway inflammation in mice by inhibiting phosphorylation of p38 and IκB and blocking the activation of MAPK and NF-κB signaling pathways, and the effective components were related to the peptides and organic acids in PTNAs. The above results lay a foundation for the research on the mechanism and material basis of Pinelliae Rhizoma in antagonizing airway inflammation.

Effect of acupuncture for regulating spleen and stomach on aspirin resistance in patients with type 2 diabetes mellitus: a randomized controlled trial / 中国针灸

OBJECTIVE@#To observe the effect of acupuncture for regulating spleen and stomach on aspirin resistance in patients with type 2 diabetes mellitus (T2DM) and explore the effect mechanism.@*METHODS@#A total of 68 T2DM patients complicated with aspirin resistance were randomized into an observation group and a control group, 34 cases in each one. On the base of the conventional treatment for diabetes, aspirin enteric-coated tablets were prescribed for oral administration, 100 mg each time, once daily in the control group. In the observation group, on the basis of the treatment as the control group, acupuncture was used for regulating spleen and stomach at Zhongwan (CV 12), Zusanli (ST 36), Yinlingquan (SP 9), Hegu (LI 4), etc., once daily. The treatment for 1 week was as one course and 4 courses of treatment were required totally in two groups. Before and After treatment, the indexes of platelet function (platelet aggregation rate [PAG] and salicylic acid concentration), the indexes of vascular endothelial function (6-keone prostaglandin F1α[6-keto-PGF1α], thromin B2 [TXB2] and cyclooxysynthase-2 [COX-2]), blood glucose (fasting plasma glucose [FPG], 2 h plasma glucose [2h PG] and glycosylated hemoglobin [HbA1c]), insulin resistance index (HOMA-IR), blood lipid indexes (total cholesterol [TC], triacylglycerol [TG], high-density lipoprotein cholesterol [HDL-C] and low-density lipoprotein cholesterol [LDL-C]) and the total score of TCM symptoms were observed in the patients of two groups. Clinical therapeutic effect and safety was compared in the patients between the two groups after treatment and the recurrence rate of cardiocerebrovascular events was followed up 6 months after treatment.@*RESULTS@#After treatment, PAG, salicylic acid concentration, TXB2, COX-2, FPG, 2h PG, HbA1c, HOMA-IR, LDL-C, TC, TG and the total scores of TCM symptoms were all reduced as compared with those before treatment in the two groups (@*CONCLUSION@#Acupuncture for regulating spleen and stomach combined with aspirin enteric-coated tablets relieve insulin resistance and reduces blood glucose and lipid as well as the recurrence rate of cardiocerebrovascular events in the patients with T2DM, which is probably related to the regulation of insulin resistance and the improvement of vascular endothelial function. This combined therapy achieves the better effect on aspirin resistance as compared with simple aspirin enteric-coated tablets.

Efficacy of 1 384 cases of peritoneal carcinomatosis underwent cytoreductive surgery plus hyperthermic intraperitoneal chemotherapy / 中华胃肠外科杂志

Objective: Peritoneal carcinomatosis refers to a group of heterogeneous (primary or secondary) malignancies in the surface of the peritoneum. Cytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC) is a comprehensive treatment strategy aiming at peritoneal carcinomatosis. This study analyzed the efficacy and safety of CRS+HIPEC in patients with peritoneal carcinomatosis, and explored prognostic factors. Methods: In this descriptive case-series study, the clinicopathological data of 1384 consecutive patients with peritoneal carcinomatosis treated in Zhongnan Hospital of Wuhan University (330 patients) and Shijitan Hospital of Capital Medical University (1054 patients) from January 2004 to January 2020 were collected retrospectively. Treatment patterns of CRS+HIPEC characteristics (operative time, number of resected organs, number of stripped peritoneum, number of anastomosis, and HIPEC regimens), safety [blood loss volume, postoperative severe adverse event (SAE) and treatment outcome], survival time and prognostic factors influencing survival were analyzed. The SAE was defined as grade III-IV adverse event according to the Peritoneal Surface Oncology Group International Textbook. Perioperative period was defined from the day of CRS+HIPEC to postoperative 30th day. OS was calculated from the day of CRS+HIPEC to the date of death or the last follow-up. Kaplan-Meier method was used for survival analysis, and log-rank test was used for comparison between groups. Cox regression model was used to identify the prognostic factors. Results: Among 1384 peritoneal carcinomatosis patients, 529 (38.2%) were male; median age was 55 (10-87) years old; median body mass index (BMI) was 22.6 kg/m(2); peritoneal carcinomatosis of 164 (11.8%) patients were from gastric cancer, 287 (20.7%) from colorectal cancer, 356 (25.7%) from pseudomyxoma peritonei, 90 (6.5%) from malignant peritoneal mesothelioma, 300 (21.7%) from gynecological cancer or primary peritoneal carcinoma, and 187 (13.5%) from retroperitoneal sarcoma, lung cancer, breast cancer, and other rare tumors. The median duration of CRS+HIPEC was 595 (90-1170) minutes, median number of resected organs was 2 (0-10), median number of resected peritoneal area were 4 (0-9), median peritoneal cancer index (PCI) was 21(1-39). Completeness of cytoreduction (CC) score of 0-1 was observed in 857 cases (61.9%). Regarding HIPEC regimens, there were 917 cases (66.3%) with cisplatin plus docetaxel, 183 cases (13.2%) with cisplatin plus mitomycin, 43 cases (3.1%) with adriamycin plus ifosfamide, and the other 240 cases (17.3%) with modified regimens. Perioperative SAE developed in 331 peritoneal carcinomatosis patients (23.9%) with 500 cases, of whom 21 patients (1.5%) died during the perioperative period due to ineffective treatment, while the others recovered after active treatment. During median follow-up time of 8.6 (0.3-82.7) months, there were 414 deaths (29.9%). The median OS was 38.2 months (95% CI: 30.6-45.8), and the 1-, 3-, 5-year survival rate was 73.5%, 50.4% and 39.3%, respectively. The median OS of peritoneal carcinomatosis patients from gastric cancer, colorectal cancer, pseudomyxoma peritonei, malignant peritoneal mesothelioma and female genital cancer or primary peritoneal carcinomatosis was 11.3 months (95% CI: 8.9-13.8), 18.1 months (95% CI: 13.5-22.6), 59.7 months (95% CI: 48.0-71.4), 19.5 months (95% CI: 6.0-33.0) and 51.7 months (95% CI: 14.6-88.8), respectively, and the difference among groups was statistically significant (P<0.001). Univariate and multivariate analyses revealed that the primary gastric cancer (HR=4.639, 95% CI: 1.692-12.724), primary colorectal cancer (HR=4.292, 95% CI: 1.957-9.420), primary malignant peritoneal mesothelioma (HR=2.741, 95% CI: 1.162-6.466), Karnofsky performance status (KPS) score of 60 (HR=4.606, 95% CI: 2.144-9.895), KPS score of 70 (HR=3.434, 95% CI: 1.977-5.965), CC score of 1 (HR=2.683, 95% CI: 1.440~4.999), CC score of 2-3 (HR=3.661,95% CI: 1.956-6.852) and perioperative SAE (HR=2.588, 95% CI: 1.846-3.629) were independent prognostic factors influencing survival with statistically significant differences (all P<0.05). Conclusions: CRS+HIPEC is an effective integrated treatment strategy for patients with peritoneal carcinomatosis, which can prolong survival with acceptable safety. Preoperative evaluation of patients' general condition is necessary and CRS+HIPEC should be carefully considered to perform for patients with preoperative KPS score <80. During the operation, the optimal CRS should be achieved on condition that safety is granted. In addition, it is necessary to prevent perioperative SAE to reduce the risk of death in peritoneal carcinomatosis patients.

Clinical Observation of Modified Zhizhutang in Treatment of Senile Primary Constipation Due to Qi-Yin Deficiency / 中国实验方剂学杂志

Objective:To explore the clinical efficacy of modified Zhizhutang in treating senile primary constipation due to Qi-Yin deficiency and its influences on gastrointestinal neurotransmitters and gastrointestinal motility. Method:One hundred and twenty-one eligible patients were randomly divided into a control group （<italic>n</italic>=60） and an observation group （<italic>n</italic>=61）. On the basis of lifestyle adjustments， patients in the control group further received oral Qihuang Tongmi soft capsule，three capsules per time，three times per day， whereas those in the observation group were further treated with modified Zhizhutang，one bag per day， for eight successive weeks. The number of complete spontaneous bowel movements （CSBM， normal defecation was considered if CSBM ≥ three times per week） before and after treatment was recorded. The main symptoms of constipation，the patient assessment of constipation quality of life （PAC-QOL）， and the traditional Chinese medicine （TCM） syndrome before and after treatment were scored， followed by the anorectal pressure measurement and colonic transit test before and after treatment. The levels of somatostatin （SS），motilin （MTL），substance P （SP） and vasoactive intestinal peptide （VIP） before and after treatment were detected. Result:The weekly average number of CSBM in the observation group was greater than that of the control group （<italic>P</italic><0.01）， but the TCM syndrome score was lower than that of the control group （<italic>P</italic><0.01）. The normal defecation rate in the observation group was 57.38% （35/61），which was higher than 35% （21/60） of the control group （<italic>χ</italic>²=6.092，<italic>P</italic><0.05）. The scores of the main symptoms of constipation in the observation group were significantly lower than those in the control group （<italic>P</italic><0.01）. The PAC-QOL subscale scores and the total score of the observation group significantly declined as compared with those of the control group （<italic>P</italic><0.01）. The anal resting pressure and anal maximum systolic pressure of the observation group were higher than those of the control group （<italic>P</italic><0.01），while the first sensation volume， urge sensation volume and maximum tolerable volume were lower （<italic>P</italic><0.01）. The excretion rates of markers in the observation group at 24 h，48 h and 72 h were significantly elevated in comparison with those in the control group （<italic>P</italic><0.01）. Compared with the control group， the observation group also exhibited increased serum MTL and SP （<italic>P</italic><0.01） and decreased SS and VIP （<italic>P</italic><0.01）. The recurrence rate in the observation group was 34.29% （12/35），obviously lower than 61.90% （13/21） in the control group （<italic>χ</italic>²=5.051，<italic>P</italic><0.05）. The total effective rates in the observation group and the control group were 95.08% （58/61） and 81.67% （49/60） ， implying a significant difference （<italic>χ</italic>²=5.321，<italic>P</italic><0.01）. Conclusion:For the elderly with primary constipation due to Qi-Yin deficiency， oral administration of modified Zhizhutang helps to regulate gastrointestinal neurotransmitters，improve gastrointestinal motility and gastrointestinal emptying rate， alleviate the symptoms of constipation， restore spontaneous bowel movements， improve their quality of life， and lower the recurrence rate. Its clinical effects were better than those of Qihuang Tongmi soft capsule.

The mechanistic effect of bromelain and papain on tenderization in jumbo squid (Dosidicus gigas) muscle.

Jumbo squid (Dosidicus gigas) muscle is rather hard and tough, which directly affects consumer acceptance. In this study, the tenderization effect of bromelain and papain on squid muscle during enzymolysis is examined and compared with an untreated control and water-treated sample. Squid mantle were incubated with different solutions (water, bromelain, and papain solution) for 40 min in a 30 °C water bath. Then, the mantle samples were subjected to water holding capacity (WHC) analysis, texture evaluation, biochemical determination, and histological observations. The results revealed that bromelain and papain disadvantageously decrease the water holding capacity when compared to the control and water-treated samples. Furthermore, following tenderization with bromelain or papain, muscle hardness, shear force, myofibrillar protein content, and Ca2+ ATPase activity were all significantly decreased. Additionally, some essential amino acids were released following tenderization. When examining the myofibrillar fragmentation index (MFI), bromelain and papain were shown to cause high levels of hydrolysis in myofibrillar and sarcoplasmic proteins. Moreover, microstructural imaging indicated that the tenderization treatments disrupted myofibrils and generated a larger number of small fragments in the muscle tissues, subsequently decreasing microstructure stability and integrity. SDS-PAGE analysis confirmed that bromelain and papain have a high proteolytic activity, with some small peptides and/or short fragments detected post-tenderization. The results presented herein demonstrated that bromelain and papain improved squid muscle tenderness and can be utilized to ensure a more desirable squid product.

Supramolecular self-assembly of a hybrid 'hyalurosome' for targeted photothermal therapy in non-small cell lung cancer.

Despite the excellent efficacy and low toxicity of photoresponse therapy, which has attracted considerable attention for use in non-small cell lung cancer (NSCLC) therapy, unsatisfactory cellular permeability, and instability, both in vitro and in vivo have limited further clinical applications of indole cyanine photosensitizers. Here, we explore the supramolecular self-assembly of a 'hyalurosome' that is mediated by calcium phosphate nanonuclei. Through hyaluronate-mediated CD44 targeting, the constructed hyalurosome specifically delivers ICG into NSCLC cells and then induces severe hyperthermia accompanied by the generation of singlet oxygen upon photoirradiation. In contrast to the action of the native form, indocyanine green encapsulated in a hyalurosome showed significantly increased cellular endocytosis and inhibited cell proliferation both in vitro and in vivo. Our study indicated that this hyalurosome is a promising candidate for the targeted delivery of photosensitizers, which may be useful in NSCLC therapy.

Discussion on the needling technique with filiform needle in acupuncture-moxibustion teaching materials in the Republic of China / 中国针灸

Through collecting the literature data of the needling technique with filiform needle in 20 acupuncture-moxibustion teaching materials in the Republic of China， the manipulation techniques with filiform needle were analyzed, such as the technique of needle insertion, the technique of reinforcing and reducing, and the management of acupuncture abnormal conditions, as well as manual techniques and analgesics methods. It is found that the era of the Republic of China was the transition period of traditional acupuncture techniques to the modern ones in acupuncture-moxibustion teaching materials, in which, the twirling technique was predominated in the technique of needle insertion. In that period, the insertion technique of tube needle had been introduced and simplified, the theory and method of the new-style technique of reinforcing and reducing were emerged and the types of acupuncture abnormal conditions recorded in the teaching materials were different from those at present. Additionally, the applicable manipulation had not been specified nationally. There were the highly influential teaching materials, i.e. , and . The acupuncture-moxibustion teaching materials in the Republic of China has been influenced by the transition of acupuncture-moxibustion education modes, the introduction of Chinese-translation version of Japanese acupuncture-moxibustion books, the academic thoughts of acupuncture masters and the manufacturing process of needle devices.

External application of two unrestricted herbal medicines to treat costochondritis in a young collegiate athlete: A case report / 中西医结合学报

Costochondritis (ChC), especially chronic ChC, typically manifests as spontaneous vague pain in anterior chest area and often occurs in adolescents for unknown reasons; it has prevented many collegiate athletes from participating in physical training and competitions. A 21-year-old female collegiate taekwondo athlete suffering from chronic chest pain was sent by her coaches for diagnosis and treatment. Seated motion palpation was used to identify spontaneous and motion-involved pain areas. Palpation in the supine position was used to initially rule out breast diseases. X-ray, electrocardiogram, and cardiac Doppler ultrasound were used in conjunction with myocardial enzyme testing to rule out lung and cardiovascular diseases. The patient was treated using herbal medicines applied via an external patch. The medicine was comprised of Rhizoma Corydalis and borneol, and the treatment lasted for seven weeks. For five weeks patches were applied at a frequency of two or three times per day, followed by a two-week period of once per day. The patient reported that the pain was relieved after two weeks of external herb use, and the autonomic chest pain had resolved. Re-examination after one month showed that her upper limb range of motion was close to normal, and her psychological burden had almost disappeared. It is possible to seek more active medicinal treatment and more practical external products for young athletes who is suffering chronic ChC that affects the sport training and competitive performances.
