ObjectiveBased on traditional quality evaluation of Gardeniae Fructus(GF) recorded in historical materia medica, this study systematically compared the quality differences between wild and cultivated GF from morphological characteristics, microscopic features, and contents of primary and secondary metabolites. MethodsVernier calipers and analytical balances were used to measure the length, diameter and individual fruit weight of wild and cultivated GF, and the aspect ratio was calculated. A colorimeter was used to determine the chromaticity value of wild and cultivated GF, and the paraffin sections of them were prepared by safranin-fast green staining and examined under an optical microscope to observe their microstructure. Subsequently, the contents of water-soluble and alcohol-soluble extracts of wild and cultivated GF were detected by hot immersion method under the general rule 2201 in volume Ⅳ of the 2020 edition of the Pharmacopoeia of the People's Republic of China, the starch content was measured by anthrone colorimetric method, the content of total polysaccharides was determined by phenol-sulfuric acid colorimetric method, the sucrose content was determined by high performance liquid chromatography coupled with evaporative light scattering detection(HPLC-ELSD), and the contents of representative components in them were measured by ultra-performance liquid chromatography(UPLC). Finally, correlation analysis was conducted between quality traits and phenotypic traits, combined with multivariate statistical analysis methods such as principal component analysis(PCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA), key differential components between wild and cultivated GF were screened. ResultsIn terms of traits, the wild GF fruits were smaller, exhibiting reddish yellow or brownish red hues with significant variation between batches. While the cultivated GF fruits are larger, displaying deeper orange-red or brownish red. The diameter and individual fruit weight of cultivated GF were significantly greater than those of wild GF, while the blue-yellow value(b*) of wild GF was significantly higher than that of cultivated GF. In the microstructure, the mesocarp of wild GF contained numerous scattered calcium oxalate cluster crystals, while the endocarp contained stone cell class round, polygonal or tangential prolongation, undeveloped seeds were visible within the fruit. In contrast, the mesocarp of cultivated GF contained few calcium oxalate cluster crystals, or some batches exhibited extremely numerous cluster crystals. The stone cells in the endocarp were predominantly round-like, with the innermost layer arranged in a grid pattern. Seeds were basically mature, and only a few immature seeds existed in some batches. Regarding primary metabolite content, wild GF exhibited significantly higher total polysaccharide level than cultivated GF(P<0.01). In category-specific component content, wild GF exhibited significantly higher levels of total flavonoids and total polyphenols compared to cultivated GF(P<0.01). Analysis of 12 secondary metabolites revealed that wild GF exhibited significantly higher levels of Shanzhiside, deacetyl asperulosidic acid methyl ester, gardenoside and chlorogenic acid compared to cultivated GF(P<0.01). Conversely, the contents of genipin 1-gentiobioside, geniposide and genipin were significantly lower in wild GF(P<0.01). ConclusionThere are significant differences between wild and cultivated GF in terms of traits, microstructure, and contents of primary and secondary metabolites. At present, the quality evaluation system of cultivated GF remains incomplete, and this study provides a reference for guiding the production of high-quality GF medicinal materials.

This article systematically analyzed the historical evolution of the origin, scientific name, producing area, quality evaluation, harvesting and processing, and other aspects of Quisqualis Fructus by consulting the ancient materia medica, medical books, prescription books, local literature and combining with the modern literature and standards, summarized and explored the development rules of its medicinal properties and efficacy along with their underlying causes, in order to provide support for the development and utilization of famous classical formulas containing this herb. According to the textual research, Shijunzi was first recorded as Liuqiuzi in Nanfang Caomuzhuang of the Jin dynasty, and the name of Shijunzi was first used in Kaibao Bencao of the Song dynasty, which has been consistently used throughout subsequent dynasties, and there were also aliases such as Junziren, Sijunzi, and Dujilizi. The mainstream source of Quisqualis Fructus used in the past dynasties has been the dried mature fruits of Quisqualis indica, a plant belonging to the family Combretaceae. In modern times, its variety Q. indica var. villosa has also been recorded as the medicinal material of Quisqualis Fructus. In 2007, the Flora of China(English edition) designated Q. indica var. villosa as a synonym of Q. indica. Today, the accepted name of Shijunzi is updated to Combretum indicum. According to ancient herbal records, the producing areas of Quisqualis Fructus were Guangdong, Hong Kong, Macao, Guangxi, Hainan, Sichuan and Fujian, and then gradually expanded to Yunnan, Taiwan, Jiangxi and Guizhou. Since the Song dynasty, two major production regions have gradually emerged in Sichuan, Chongqing and Fujian. Currently, it is primarily cultivated in Chongqing, Guangxi and other areas, with Chongqing yielding the highest output. Since modern times, superior quality has been defined by large size, a purple-black surface, plump grains, and a yellowish-white kernel. According to ancient herbal records, the harvesting period of Quisqualis Fructus was the July and August of the lunar calendar, mostly used raw after shelling or with the shell intact, it underwent processing methods such as cleaning, slicing, mixing, steaming, roasting, stewing, and frying. Currently, the harvesting period is autumn, followed by sun-drying or low-heat drying, with processing methods including cleaning, stir-frying, and stewing. In ancient and modern literature, the records of the properties, functions and indications of Quisqualis Fructus are basically the same, that is, sweet in taste, warm in nature, predominantly non-toxic, belonging to the spleen and stomach meridians. It possesses effects of insecticide, decontamination and invigorating spleen for ascariasis, enterobiasis, abdominal pain due to worm accumulation and infantile malnutrition.The contraindications for use primarily include avoiding consumption by individuals without parasitic infestations, limiting use for those with spleen-stomach deficiency-cold, refraining from drinking hot tea during medication, and avoiding excessive intake. Based on the textual research, it is suggested that the dried mature fruits of Q. indica should be used as the medicinal material for the development of famous classical formulas containing Quisqualis Fructus. Processing methods may be chosen according to prescription requirements, and the raw products is recommended for medicinal use if not specified.

The Proctor's reporting guideline for implementation strategies represents a landmark framework in the field of implementation science, aiming to address the issue of inconsistent reporting in implementation research by standardizing the naming, definition, and operationalization of implementation strategies, thereby enhancing the credibility and utility of research findings. This paper provides an in-depth interpretation of the core connotations of this reporting guideline and illustrates its application in developing interview outlines and specifying implementation strategies, using a brief smoking cessation intervention project as a case study. Through this reporting guideline, abstract recommendations for implementation are systematically transformed into clear, multidimensional operational guides, significantly improving the transparency of strategy connotations and the replicability of actual execution. Meanwhile, the case study highlights the flexibility of the guideline, which allows researchers to adapt the content and format of strategies based on local resources and cultural contexts, thus enhancing practical adaptability while maintaining scientific rigor. However, the application of Proctor's reporting guideline still faces challenges, primarily manifested in the potential confusion surrounding the constructs of temporality and dose in practice, as well as the challenges that the inherent flexibility of the guideline may pose to the assessment of fidelity and effectiveness. Despite these limitations, the reporting guideline remains a vital tool for implementation research; future efforts should focus on optimizing its application—through refining operational guidelines, standardizing flexible adaptations, and involving stakeholders—to better guide implementation studies and continuously promote high-quality development in the field.

BACKGROUND:Traditional methods of urinary tract reconstruction are limited by donor scarcity,high complication rates,and suboptimal functional recovery.Tissue engineering strategies offer new directions in this field.Since the urinary tract is mainly composed of muscle tissue,the key is to find suitable seed cells and efficiently induce them to differentiate into smooth muscle cells.Comparative studies on the efficacy of different smooth muscle cell induction regimens are still lacking. OBJECTIVE:To isolate,culture,and identify human urine-derived stem cells,and to compare the effects of two different induction protocols. METHODS:Human urine-derived stem cells were isolated from urine samples of 11 healthy adult volunteers by multiple centrifugations.Surface markers were identified by flow cytometry.The multi-directional differentiation potential of human urine-derived stem cells was verified through osteogenic and adipogenic differentiation.Differentiation was induced by transforming growth factor-β1 or transforming growth factor-β1 combined with platelet derived growth factor for 14 days.Immunofluorescence staining and western blot assay were employed to compare the expression differences of smooth muscle-specific proteins(α-SMA and SM22). RESULTS AND CONCLUSION:(1)Urine-derived stem cells were successfully isolated from the eight urine samples of healthy people.These cells exhibit a"rice grain"-like morphology and possess a robust proliferative capacity.(2)Urine-derived stem cells exhibited high expression of mesenchymal stem cell surface markers(CD73,CD90,and CD44)and extremely low expression of hematopoietic stem cell surface markers(CD34 and CD45).These cells did not express CD19,CD105,and HLA-DR.(3)After osteogenic and adipogenic differentiation,the formation of calcium nodules and lipid droplets was observed,with positive staining results from Alizarin Red S and Oil Red O staining.(4)After 14 days of smooth muscle induction culture,immunofluorescence staining revealed that the smooth muscle differentiation rate of urine-derived stem cells treated with a combination of transforming growth factor-β1 and platelet derived growth factor was significantly higher compared to those treated with transforming growth factor-β1 alone(P<0.005).(5)After 14 days of smooth muscle induction culture,western blot assay further demonstrated that the expression levels of α-SMA and SM22 in the transforming growth factor-β1/platelet derived growth factor group were significantly elevated compared to those in the transforming growth factor-β1 only group(P<0.005).These findings confirm that urine-derived stem cells can be non-invasively isolated using multiple rounds of centrifugation.Compared with transforming growth factor-β1 alone,the combination of transforming growth factor-β1 and platelet derived growth factor can improve the efficiency of inducing urine-derived stem cells to differentiate into smooth muscle cells.

The medicinal use of Malvae Semen has a long history. In this paper, by consulting the ancient materia medica, prescription, agronomy, literature and other aspects of the classics, the name, origin, evolution of scientific name, quality, harvesting and processing, functions and indications and others of Malvae Semen were systematically sorted out and verified, so as to provide a basis for the development and utilization of famous classical formulas containing this herb. According to the textual research, Shennong Bencaojing began to use Dongkuizi as the correct name, which was used in the past dynasties, and there were also aliases such as Kuicaizi, Huacai, and Kuizi. Through the original research, it can be seen that Kuicai is the mainstream original plant of Malvae Semen, that is, Malva verticillata var. crispa, the Alcea rosea and M. cathayensis are also used. In modern times, the seeds of Abutilon theophrasti have been passed off as Malvae Semen, while the seeds of M. verticillata var. crispa have rarely been used in medicine. And Abutili Semen has been another medicinal material with different efficacy since the collection of Newly Revised Materia Medica in the Tang dynasty. Since the Ming and Qing dynasties, the cultivation of Kuicai has been decreasing, while A. theophrasti is more common and easy to obtain, and Abutili Semen and Malvae Semen are similar in morphology and confused, which should be corrected. In addition, Malvae Fructus is a Mongolian customary medicinal herb, which is different from the traditional use of seeds in traditional Chinese medicine. Kuicai, as an important vegetable in history, was widely cultivated and gradually shrunk after the Song dynasty, it is now mainly produced in southern provinces. The quality evaluation of Malvae Semen is better for those with dry bodies, full grain, grayish brown color, no mud, and no impurities. The harvesting is generally in the autumn and winter. After drying, it is seeded, sieved peel and impurities, mashed, or slightly stir-fried to yellow-white color with gentle fire. It is sweet, cold and slippery in nature and taste, with the main effects of laxation, diuresis, lactation and elimination of swelling. The efficacy of Abutili Semen is clearing heat and removing toxicity, promoting diuresis and removing nebula, the efficacy is quite different from that of Malvae Semen. Based on the results of textual research, it is suggested that M. verticillata var. crispa should be used as the medicinal source of Malvae Semen in the development of famous classical formulas, the corresponding processing methods should be selected according to the requirements of drug processing in the formulas, while the raw products are recommended to be used if the processing is not specified.

In this paper, the name, origin, producing area, harvesting, processing and functional indications of Arcae Concha were systematically combed and verified by consulting the ancient and modern literature, in order to provide a basis for the development of famous classical formulas containing Arcae Concha. Arcae Concha was first recorded in the name of Han in Bencao Shiyi, but later, due to the influence of LI Shizhen's error of combining Han item with Kuiha in the Ming dynasty, there were aliases such as Kuilu and Fulao, and Yizong Bidu began to include Walengzi as its correct name and has been used ever since. The textual descriptions and illustrations of the medicinal materials of Arcae Concha contained in the materia medica of the past generations were consistent with the modern Arca inflata, A. subcrenata and A. granosa. In ancient times, there were medicinal records of two parts of shell and meat, but now the shell is used as medicine, and the meat is mostly edible. In ancient times, Zhejiang, Shandong, Guangdong and Guangxi were the main producing areas, and Zhejiang was the best. It is now believed that A. inflata is mostly distributed in the northern part of the Huanghai Sea, A. granosa is mostly distributed in the coastal areas south of Shandong Peninsula in China, and A. subcrenata is widely distributed in the coastal areas of China. Its quality is better in a complete, white, no residual meat and sand. In ancient times, there was no clear harvesting period, and the processing was mainly based on vinegar quenching after calcination or powdering of calcined shell, but now the harvesting period is autumn and winter. After harvesting, it is directly washed and crushed for raw use or processed by calcined method. The records of the medicinal materials in the past dynasties on the properties of Arcae Concha were mainly warm, sweet, salty and mild, and it is now believed that Arcae Concha is salty in taste and mild in nature. In ancient times, it was believed that Arcae Concha were mainly used for coldness in the heart and abdomen, coldness in the waist and spine, benefiting the five internal organs, strengthening the stomach. Nowadays, it is believed that Arcae Concha can eliminate phlegm and remove blood stasis, soften the hardness and dissipate the lumps, produce acid and relieve pain. It can be used in the treatment of stubborn phlegm, gall tumor, scrofula and other symptoms. In conclusion, it is suggested that for the famous classical formulas containing Arcae Concha, the corresponding methods should be selected according to the processing requirements of the drug in the formulas, while those without processing requirements can be determined according to the functional position of the products.

[Objective] To explore the effectiveness of applying the PDCA (Plan-Do-Check-Act) cycle to enhance the compatibility rate of five Rh blood group antigen phenotypes between donors and recipients across multiple hospital campuses. [Methods] Clinical blood transfusion data from May to July 2022 were selected. Specific improvement measures were formulated based on the survey results, and the PDCA cycle management model was implemented from August 2022. The post-intervention phase spanned from August 2022 to October 2023. The Rh phenotype compatibility rate, the detection rate of Rh system antibodies, and the proportion of Rh system antibodies among unexpected antibodies were compared between the pre-intervention phase (May to July 2022) and the post-intervention phase. [Results] After the continuous improvement with the PDCA cycle, the compatibility rate for the five Rh blood group antigen phenotypes between donors and recipients from August to October 2023 reached 81.90%, significantly higher than the 70.54% recorded during the pre-intervention phase (May to July 2022, P<0.01), and displayed a quarterly upward trend (β=0.028, P<0.05). The detection rate of Rh blood group system antibodies (β=-9.839×10-5, P<0.05) and its proportion among all detected antibodies (β=-0.022, P<0.05) showed a quarterly decreasing trend, both demonstrating a negative correlation with the enhanced compatibility rate (r values of -0.981 and -0.911, respectively; P<0.05). [Conclusion] The implementation of targeted measures through the PDCA cycle can effectively increase the compatibility rate of five Rh blood group antigen phenotypes between donors and recipients, reduce the occurrence of unexpected Rh blood group antibodies, thereby lowering the risk of transfusion and enhancing the quality and safety of medical care.
