ABSTRACT

Parkinson's disease (PD) is a chronic neurodegenerative disease. At present, levodopa and other drugs are mainly used for dopamine supplementation therapy. However, the absorption of levodopa in the gastrointestinal tract is unstable and its half-life is short, and long-term use of levodopa will lead to the end-of-dose deterioration, dyskinesia, the "ON-OFF" phenomenon and other symptoms. Therefore, new preparations need to be developed to improve drug efficacy, reduce side effects or improve compliance of patients. Based on the above clinical needs, this review briefly introduced the preparation modification strategies for the treatment of PD through case analysis, in order to provide references for the research and development of related preparations.

ABSTRACT

As a glucocorticoid drug with wide clinical application, triamcinolone acetonide can be administered by multiple routes, such as eye, nose, joint cavity, and skin, for the treatment of various local diseases such as arthritis, macular edema, rhinitis, and urticaria. As a drug with extremely low solubility in water, the dose form of triamcinolone acetonide is closely correlated with administration route and site. The dosage form of triamcinolone acetonide administered via injection(including joint cavity injection, vitreous injection, suprachoroidal injection, intramuscular injection) is mainly suspension, and the representative drugs include Kenalog-40®, Zilretta®, Triesence®, Xipere®, etc.; the dosage forms of nasal mucosal administration are mostly sprays, and the representative drug is Nasacort®; the dosage forms of oral mucosal administration are mostly patches, ointments and creams, and the representative drug is Oracort®; the dosage forms for transdermal administration are mostly ointments, creams and lotions, and the representative drugs include Trianex®, Teva-Triacomb®, etc. At present, the research on dosage forms of triamcinolone acetonide by various administration routes mainly focuses on the construction of delivery carriers, the addition of cosolvents or the use of new delivery tools.

ABSTRACT

Background: The fact that about 90 % of newly discovered API’s or new molecular entity(NME) have little or no aqueous solubility, causes a significant protest to the initialization of development and their scale up of dosage form in the Pharma Industry. Aqueous solubility of API’s has critical role in drug dissolution or availability of drug at the site of action or bioavailability, when a dosage form is administered orally.Objective: The object of this study is to formulate a modified release tablet dosage form of a poorly aqueous soluble drug, which not only have higher aqueous solubility or bioavailability but also have sustained release characteristics with high mechanical strength &their commercial viability. Numerous techniques are available for the solubility enhancement but all individual techniques have its own limitations for commercialization.Method: Aqueous solubility of drugs is improved by the known Solubility enhancement techniques like Micronization &Solid dispersions. After successful solubility enhancement, sustained release or modified release tablets of poorly aqueous soluble drug can be easily formulated into a suitable shape or size by using a known Polymer Matrix Sintering Technology with commercial feasibility. Micronization of poorly water-soluble drugs can be performed by Air Jet Mill or Ball Mill. Whereas Solid dispersion technique involves, molecular dispersion of poorly soluble drug in a suitable inert carrier, to form an amorphous and highly soluble compounds. Sintering Technology is defined as the bonding of adjacent particle surfaces in a mass of powder, or in compact, by the application of heat. Conventional sintering technique involves the heating of compact at a temperature below the melting point of the solid constituents in a controlled environment under atmospheric pressure.Results: Enhanced solubility of poorly soluble API’s by these proposed techniques is due to either conversion of crystalline compound in to amorphous form or reduction of particle size to its molecular level by the application of Micronization or solid dispersion techniques. The developed modified release tablets will show a sustained release characteristic due to Sintering aspect and provides enhanced solubility of BCS class II or IV drugs.Conclusion: Novel modified release tablets have been designed through consolidation of Solubility enhancement and Polymer Matrix Sintering technologies. Simultaneous exploitation of well-known and established approaches- Micronization (optimum particle size reduction) or solid dispersion, optional surfactant and Polymer Matrix Sintering Technique in the recent concept, produces significant enhancement of solubility of poorly water soluble API’s without compromising the content uniformity of dosage form and also provide a modified or sustained release characteristics with high mechanical strength. The release profile of drug can be easily tailored by using combination of both techniques where challenges of low solubility are prominent.

ABSTRACT

Introduction:Good communication skills (CSs) are not only the crux of a good doctor–patient relationship but also the foundation over which any human relationship is based. The aim of this study was to assess the impact of training on CS in Phase I MBBS students in a Government Medical College in West Bengal, India. MaterialsandMethods: One hundred and eighty‑four Phase I medical students were trained on how to communicate properly with their peers, seniors, teachers, college authorities, department staff, patient relatives, and other health professionals. Each participant underwent a set of three assessments (presession, postsession, and late postsession) for both knowledge and skills in CS. After postsession assessment, feedback by the faculties and peers was provided and reflections were obtained from the participants. A prevalidated questionnaire and Gap‑Kalamazoo CS Assessment Form (with some modification) were used for knowledge and skill’s assessment, respectively. At the end of the module, feedback was collected from the participants. Data were tabulated and results were compared and interpreted. Results: Mean score and standard deviation for knowledge assessment were 5.29 ±1.35, 9 ±1.20 and 8.55 ±0.97 in T1, T2, and T3 and for skills’ score were 17.78 ±4.89, 26.32 ±5.04 and 30.77 ±3.66 in SA1, SA2, and SA3, respectively. Most participants showed improvement in T2 with mean improvement score (T2–T1) of 79.57 ±47.25 and mean retention score (T3–T1) of 71.9 ±47.84. About 52% of participants showed deterioration in T3 with late deterioration score (T3–T2) of−4.06±11.42. 33% showed no change in knowledge, i.e., they retained their improvements, whereas 15% showed further improvement. Fifty‑two percent of participants showed skills’ improvement by scores of 7–12, 43% showed retention by 13–18, and late deterioration was shown by 82%, their scores dropped by 0–6. Conclusion: The training module was successfully implemented, and participants appreciated this type of participant centric assessment‑based teaching learning module. They learned about the effective ways of communication in a fun manner and were determined to apply all that they have learned

ABSTRACT

Objectives: Trait emotional intelligence (TEI) is a key personality construct by which an individual recognizes, understands, expresses and regulates emotions in self and others to adapt to environments or achieve one’s goals. TEI skills are modifiable and have a potential to significantly influence psychological health (PH) of a person. The aims of current work were to evaluate relationship between TEI and PH of medical students and to explore the incremental validity of TEI to predict psychological distress beyond sociodemographic and educational factors in them. Materials and Methods: One hundred and thirty-two medical students (mean age 18.02 years) participated in this cross-sectional study. TEI and PH were assessed using TEI questionnaire short form (TEIQue-sf) and depression, anxiety and stress scale (DASS-21), respectively. Hierarchical multiple regression analysis was carried out to determine if scores on TEIQue-sf added significantly to the prediction of psychological symptoms in medical students. Results: There was a significant negative association (r = ?0.57, P < 0.001) between TEIQue-sf and DASS-21 scores. Hierarchical regression analyses revealed that after controlling for sociodemographic and educational variables, TEIQue-sf scores explained a statistically significant increment of variance (P < 0.001) in DASS-21 scores. TEI emerged as best predictor of psychological distress of medical students followed by educational factors. However, sociodemographic profile as an attribute failed to demonstrate significant capacity to predict PH of our participants. Conclusion: Our results indicate that TEI is a robust and unique predictor of better PH and plays a positive role in promoting psychological well-being

ABSTRACT

Objective By review of the studies comparing the measurements properties of EuroQol five-dimensional questionnaire (EQ-5D) and short-form 6-dimension health survey (SF-6D) in Chinese populations,this study aims to provide a reference for selecting,applying,and improving the health-related quality of life and health utility measurement tools for Chinese populations.Methods We retrieved the original studies which compared the two tools from both Chinese and English databases and then summarized the findings of the included studies from the measurement properties.Results A total of 12 studies were screened out,including 9 studies about diseased populations and 3 studies about the general populations.The included studies generally demonstrated that both EQ-5D and SF-6D had good feasibility,while the utility scores generated from them cannot be used interchangeably.For the diseased populations,both EQ-5D and SF-6D and their utility scores had good construct validity,including convergent and known-groups validity,while only the utility scores had good construct validity for the general populations.For the diseased populations,SF-6D had smaller ceiling effect and better sensitivity than EQ-5D-3L,while the comparison results between SF-6D and EQ-5D-5L were inconsistent.For the general populations,SF-6D also had better sensitivity than EQ-5D.In addition,there was little comparative evidence for reliability such as test-retest reliability and responsiveness between SF-6D and SF-6D in the two populations.Conclusion This review summarized the characteristics,methods,results,and conclusions of the studies that directly compared the two tools for the populations in China.Although only the studies directly comparing EQ-5D and SF-6D are included in this review,the common findings in these studies provide a basis for better comparison between the two in the future.

ABSTRACT

Objective: We examined the descriptions of reference information regarding the dispensing process in the interview form (IF). If there was no description, we determined the test data’s availability from the pharmaceutical company.Methods: The survey targeted 78 drugs that complied with the new description IF guidelines, for regular tablets and capsules launched from April 2018 to December 2021. The survey was conducted between March 13th and June 14th, 2022. We investigated the reference information regarding the stability of the medications during the crushing and simple suspension method during dispensing.Results: Regarding the data related to the stability of medications during the crushing process, ten drugs were described as having “data available,” 18 drugs were to be “inquired individually,” 31 drugs had “no applicable data,” and 14 drugs had “no items.” Regarding the status of descriptions on the simple suspension method, ten drugs were described as having “data available,” 18 drugs had data that was to be “inquired individually,” 32 drugs had “no applicable data,” and 14 drugs had “no items.” Regarding the 35 drugs for which both the stability during crushing and the simple suspension method were listed as either “no applicable data” or “no items,” we contacted the pharmaceutical companies to inquire about the test data for the stability during the crushing and simple suspension method. We found that four drugs had “data available” on the stability of medications during the crushing process, while six drugs had “data available” on the simple suspension method.Conclusion: Many IFs that complied with the new description guidelines had items for reference information regarding dispensing. However, the test data’s description was not sufficient. Furthermore, even if there is no description of reference information regarding dispensing in the IF, we confirmed that the pharmaceutical company owns the test data.

ABSTRACT

Protein polypeptides and polysaccharides, the indispensable macromolecular active components in traditional Chinese medicine, are widely found in Chinese medicine decoction after the decoction of traditional Chinese medicine. However, through oral administration, these macromolecules are digested by the stomach and intestine and thus fail to be absorbed in prototype. This is inconsistent with the actual clinical efficacy of Chinese medicine decoction. According to modern research, new phase structures and effects of the macromolecules emerge during the decoction of traditional Chinese medicine, but the phase change law caused by the interaction among the components of traditional Chinese medicine and the relationship between phase structure and effect are still unclear. Thus, this study reviewed the oral absorption of macromolecular components of traditional Chinese medicine, analyzed the internal relationship of the form of macromolecules in traditional Chinese medicine with the absorption and effect based on phase structure, and summarized the research mode of oral absorption and effect of macromolecules in traditional Chinese medicine with phase structures as the core, providing new ideas and methods for future research.

ABSTRACT

OBJECTIVE To promote the standardization and integrity of the informed consent form for clinical trials of registered anti-tumor drugs, and to protect the legitimate rights and interests of the subjects. METHODS The ethical review resolutions of clinical trial projects of registered anti-tumor drugs that were initially reviewed by the Ethics Committee of our hospital from July 1st, 2020 to July 1st, 2022 were summarized to statistically analyze the problematic items according to the “Quality Analysis Form of Informed Consent” prepared by our hospital. RESULTS Of the 316 clinical trials of registered anti- tumor drugs that were initially reviewed, 257 (81.3%) had problems with the contents of informed consent form, mainly domestic multi-center trials and phase Ⅲ trials. The main problems included the vague notification of the test fee bearer (68.5%), the incomplete notification of the test content (59.1%), the insufficient notification of rights and interests and risks (58.4%), the insufficient notification of personal information protection (56.0%), and the nonstandard expression of the informed consent form (52.5%). CONCLUSIONS There is still a gap between the informed consent form of the clinical trials of registered anti-tumor drugs in our hospital and the requirements of the new version of Good Clinical Practice for Drugs (GCP). The parties involved in the test can take a number of measures to improve the standardization and integrity of the informed consent form, and the research team should design the informed consent form in strict accordance with the requirements of the new GCP and pay attention to the comprehensive notification about the test. The Ethics Committee can provide the sponsor and researcher with the template of informed consent form and the key points of writing, continue to strengthen the examination ability, improve the examination quality, and effectively protect the safety and interests of the subjects.

ABSTRACT

In recent years, the use of active substances as excipients or as substitutes for other excipients in the design of modern drug delivery systems has received widespread attention, which has promoted the development of the theory of unification of medicines and excipients in the design of traditional Chinese medicine(TCM) preparations. Adopting the theory of unification of medicines and excipients to design drug delivery systems can reduce the use of excipients and thus the cost of preparations, reduce drug toxicity, increase drug solubility and biocompatibility, enhance synergistic effect, and realize targeted delivery and simultaneous delivery of multiple components. However, the research on the application of this theory in the modern drug delivery system of TCM preparations is still insufficient, with few relevant articles. In addition, the TCM active substances that can be used as the excipients remain to be catalogued. In this paper, we review the types and applications of the drug delivery systems with TCM active substances as excipients and describe their common construction methods and mechanisms, aiming to provide references for the in-depth research on the modern drug delivery systems for TCM preparations.

ABSTRACT

Cordyceps, a unique precious Chinese herbal medicine in China, has the effects of tonifying the kidney and lungs, stopping bleeding, and resolving phlegm. It has definite clinical effects on diabetes, respiratory diseases (such as chronic obstructive pulmonary disease), chronic kidney diseases, slow arrhythmia, and hyperlipidemia. We searched China National Knowledge Infrastructure (CNKI), Wanfang Data, VIP, SpringerLink (Biomedical Sciences), Embase, Proquest (Life Sciences), PubMed, Cochrane Library, and SinoMed for the research on the arsenic content in Cordyceps. According to statistical analysis, arsenic in Cordyceps mainly exists in the non-toxic or low-toxic form. The arsenic-containing compounds in Cordyceps may be an arsenic-sugar compound with anticancer effect. The inorganic arsenic content in Cordyceps is lower than the arsenic standard stipulated by the State Food and Drug Administration. It remains uncertain whether different measurement methods can affect the results. The total arsenic content varies in Cordyceps from different producing areas, and the general rule of total arsenic content in Cordyceps produced in different provinces, districts, and counties cannot be obtained from the results of the existing studies. The arsenic content in Cordyceps is mainly concentrated in the insect part, which is significantly different from that in stroma, and no arsenic is detected in the mycelia. The soil arsenic content in the growing areas is generally high, which may be a main reason for the high arsenic content in Cordyceps. As a valuable medicinal material for tonifying and nourishing, Cordyceps still plays an irreplaceable role in disease prevention, health care, chronic disease management, and rehabilitation.

ABSTRACT

AIM: To investigate the effect of the intravitreal injection of vascular endothelial growth factor-A165(VEGF-A165)on the scleral remodeling of guinea pigs with form-deprivation myopia(FDM).METHODS: A total of 120 tricolor guinea pigs, aged three weeks, were randomly divided into 6 groups, with 20 in each group. The blank group did not undergo any intervention. In the FDM group, only the FDM model was established. In the phosphate buffer saline(PBS)group, 2.5 μL of PBS was injected into the vitreous cavity before establishing the FDM model. In the 1ng group, 5ng group, and 10ng group, VEGF-A165 was injected into the vitreous cavity at concentrations of 1, 5 and 10ng, respectively, before the establishment of the FDM model. The FDM model was established by covering the right eyes of guinea pigs with translucent balloons for 14d. The diopter and axial length of the right eyes were measured before and after covering. After 14d, the content of dopamine(DA)in retina was measured by high performance liquid chromatography. Additionally, the mRNA and protein expression levels of matrix metalloproteinase-2(MMP-2), tissue inhibitor of matrix metalloproteinase-2(TIMP-2), transforming growth factor(TGF)-β1, TGF-β2 and α-smooth muscle actin(α-SMA)in sclera were detected by reverse transcription polymerase chain reaction(RT-PCR)and Western blot.RESULTS: Before covering, there were no significant differences in the diopter and axial length of the right eyes of guinea pigs in all groups(P&#x003E;0.05). After 14d of modeling, when compared with the blank group, FDM group showed an increase in the degree of myopia in the right eye, a prolongation of the axial length, a decrease in the content of DA in the retina, and an increase in the expression of MMP-2, TGF-β2 and α-SMA in the sclera. Conversely, the expression of TIMP-2 and TGF-β1 were decreased(P&#x003C;0.01). However, in comparison to the FDM group, the degree of myopia in the 1ng, 5ng, and 10ng groups of guinea pigs decreased, the growth trend of axial length slowed, the content of DA in the retina increased, and the expression of MMP-2, TGF-β2 and α-SMA in the sclera decreased. Furthermore, the expression of TIMP-2 and TGF-β1 in the sclera increased(P&#x003C;0.01). As the concentration of intravitreal injection of VEGF-A165 increased, the degree of myopia in the right eye of guinea pigs gradually increased, and the axial length gradually prolonged. The content of DA in the retina gradually decreased, the expression of MMP-2, TGF-β2, and α-SMA in the sclera gradually increased, while the expression of TIMP-2 and TGF-β1 decreased gradually.CONCLUSION: Intravitreal injection of VEGF-A165 can increase the content of DA in the retina of FDM guinea pigs, affect the expression of MMP-2, TIMP-2, TGF-β1, TGF-β2 and α-SMA in the sclera, and inhibit scleral remodeling of guinea pigs. Notably, the VEGF-A165 at the concentration of 1ng showed the most significant efficacy.

ABSTRACT

AIM: To investigate the effects of modified Zhujing Pill on the mitochondrion structure and dynamin-related protein of retinal pigment epithelial cells(RPEs)in mice with form deprivation myopia.METHODS: 3-week-old C57BL/6J mice were randomly divided into control group, model group and Chinese medicine group, with 10 mice in each group. Myopia model of the right eye of mice was established by means of form deprivation in model and Chinese medicine groups. After 4wk, the Chinese medicine group were given intragastric administration of modified Zhujing Pill suspension 0.546g/(kg·d)(0.2mL/d)for 4wk, and same amount of saline was given to mice in other groups at the same time of modeling. The axial length and diopter of the right eye of the mouse were measured before and after the experiment by A-ultrasound and a strip retinoscope respectively. At the end of the experiment, the mitochondrial ultrastructure of RPEs was observed by transmission electron microscope. Western blot, and real-time fluorescent quantitative PCR(q-PCR)were used to detect quantitative and gene expression of mitofusin 1(MFN1), optic atrophy 1(OPA1), and dynamin-related protein 1(DRP1)in retinal tissues respectively.RESULTS: At the beginning of the experiment, there was no statistically significant difference in axial length and diopter of the right eye of the mouse in control, model and Chinese medicine groups(P&#x003E;0.05). At the end of the experiment, compared with the control group, the mice in the model group and the Chinese medicine group had lower diopter and continuously prolonged axial length(all P&#x003C;0.05), while the mice in the Chinese medicine group had significantly shorter axial length and higher diopter than the model group(all P&#x003C;0.05). Western blot and q-PCR results showed that the relative expression of MFN1 and OPA1 decreased and DRP1 increased in both the model group and the Chinese medicine group compared with the control group(all P&#x003C;0.05), and the relative expression of MFN1 and OPA1 increased in the Chinese medicine group compared with the model group(all P&#x003C;0.05). The electron microscopic results showed that the mitochondria in the right retina of the mice were only mildly swollen in the Chinese medicine group, while the mitochondria in the model group were obviously swollen and disordered and empty.CONCLUSION: Modified Zhujing Pill could protect the retinal mitochondria by regulating the key proteins of mitochondrial dynamics(MFN1, OPA1, and DRP1), and it has a protective effect on the retina of axial myopic mice.

ABSTRACT

The new business forms are the new patterns of the job market extended by the use of mobile internet, big data, cloud computing, and other information technologies in the context of a new round of information technology development. In recent years, under the catalysis of the new employment model, a large number of new business employees have emerged such as food delivery riders, couriers, and online car-hailing drivers, whose employment forms are flexible and don’t fully conform to the establishment of labor relations with the employers, and whose problem of overtime work is common. The employment characteristics of new business forms of "focusing on performance and ignoring responsibility" make workers at great risks of occupational injuries and occupational health problems such as work-related musculoskeletal disorders, mental disorders, and overwork. However, the current research on occupational safety and health of workers in new business forms is insufficient, and the experience of institutional practice and supervision is also limited. Therefore, based on relevant research progress at home and abroad, this paper discussed the health injuries of workers in new business forms, summarized associated influencing factors from four aspects: employment form, employment affiliation, long working hours exposure, and institutional guarantee, and then proposed countermeasures to strengthen occupational safety and health protection of workers. For the current problems in the employment of new business forms, the government, enterprises, and workers need to work together to improve the legal and regulatory system for employment of new business forms, and standardize occupational safety and health management, thus effectively protect the occupational safety and health rights and interests of workers in new business forms.

ABSTRACT

Introduction@#Tracheostomy is a surgical procedure that creates a neck opening directly into the trachea, typically performed to establish an alternative airway for individuals who experience difficulty breathing as a result of certain medical conditions. Tracheostomy can be temporary or permanent, and it plays a crucial role in the management of both acute and chronic respiratory issues and can significantly improve the quality of life for those who require it.@*Objective@#This study aims to investigate the incidence, common indications and outcomes of tracheostomy in the Otorhinolaryngology-Head and Neck Surgery (ORL-HNS) department of a tertiary hospital in Manila, Philippines. @*Methodology@#This is a retrospective descriptive study including all admissions and in-patient referrals to the clinical division of the Department of Otorhinolaryngology-Head and Neck Surgery who underwent tracheostomy from January 2016 to December 2020. Data were retrieved by review of medical records and Outcome Based Evaluation (OBE) form of all patients who underwent tracheostomy during the study period.@*Results@#Our study involved 74 patients with a male-to-female ratio of 22:15. The patients' ages ranged from 5 to 89 years. Prolonged intubation was the main reason for tracheostomy, followed by upper airway obstruction due to supraglottic mass for males and vocal cord paralysis for females. Only three patients who had tracheostomy experienced complications and were managed accordingly. @*Conclusion@#Tracheostomy is one of the most valuable and reliable surgical procedures for managing airway obstructions. Proper patient and caregiver education as well as constant follow-up are crucial to prevent complications.

ABSTRACT

As a clinical compulsory course, dermatovenereology is characterized by various diseases, complex etiology, and distinct morphological characteristics, and its teaching during the probation period is faced with many challenges. Based on today′s rich educational resources on the internet, and combined with rich clinical resources in large hospitals, the traditional teacher-led lecturing during the probation period needs to be changed, and the adoption of inquiry-based defensive teaching mode has obvious advantages over the traditional teacher-led teaching mode. In the inquiry-based defensive teaching mode, clinical teachers design a series of clinical questions based on clinical topics, then introduce network teaching videos to students to change classroom teaching into students′ after-class learning, induce students to actively explore issues, encourage them to work together in groups to excavate clinical resources, make presentations and organize defense. This teaching mode turns the traditional teacher-led probationary class into a student-led and teacher-assisted speculative defense session, thereby improving learning efficiency and quality, and promoting the cultivation of students′ core literacy and comprehensive ability. Undergraduates are the main target group of this teaching mode, and this mode can also be adopted in the teaching of postgraduates and resident doctors in the standardized training program for the organization of teaching activities and optimization of assessment modes.
