Personalized traditional Chinese medicine(TCM) granules are positioned as a solid dosage form of TCM decoctions, boasting strong applicability and wide application range. The market prospect of personalized TCM granules is promising in that their preparation by mixed decoction makes up for the shortcoming of formula granules like the Chinese patent medicine granules and classical TCM prescription granules whose components cannot be changed flexibly. However, such factors as insufficient basic research, equipment mismatch, and low process commonality have limited their clinical application. After analyzing the characteristics of perso-nalized TCM granules, their production status, and the bottlenecks restricting their development, this paper pointed out the meaning and key points of developing a generalized preparation process for personalized TCM granules and affirmed the vital roles of the preparation and process prediction system and the on-line detection technology in improving the productivity of granulation. Finally, some assumptions on technology development for solving the specific problems of personalized TCM granules were shared to provide some ideas for the application and development of personalized TCM granules in clinical practice.With the continuous improvement of people's living standards and the greatly accelerated pace of life, patients' requirements for traditional Chinese medicine(TCM) pharmaceutical care are constantly raised, and personalized TCM preparations used are increasing year by year. However, a series of problems, such as the bottleneck of preparation technology, the lack of preparation specifications, and the weak legal basis for supervision, have become prominent, leading to the uneven product quality of personalized pre-parations. This paper systematically summarized and analyzed the current situation and existing problems of personalized TCM preparations, including dosage form application, preparation technology, production equipment, quality standard, clinical application, and administration mode. Additionally, it put forward an inheritance and innovation research mode of personalized TCM preparation technology based on the physical fingerprint of raw materials and innovation research and intellectual property protection mode of "research-patent-technology-equipment-standard". Furthermore, innovative development strategies were proposed, such as the production standard system of clinical preparations based on the whole process traceability and the regional processing service mode of clinical preparations based on industry 4.0. The present study is expected to provide beneficial references for the inheritance and innovation development of personalized TCM preparations.

Artificial skin (AS) is widely used in dermatology, pharmacology, and toxicology, and has great potential in transplant medicine, burn wound care, and chronic wound treatment. There is a great demand for high-quality AS product and a non-invasive detection method is highly desirable.

To quantify the constructure parameters (i.e., thickness and surface roughness) of AS samples in the culture cycle and explore the growth regularities using optical coherent tomography (OCT).

An adaptive interface detection algorithm is developed to recognize surface points in each A-scan, offering a rapid method to calculate parameters without constructing OCT B-scan pictures and further achieving realizing real-time quantification of AS thickness and surface roughness. Experiments on standard roughness plates and H&E-staining microscopy were performed as a verification.

As applied on the whole cycle of AS culture, our method's results show that during the air-liquid culture, the surface roughness of the skin first decreases and then exhibits an increase, which implies coincidence with the degree of keratinization under a microscope. And normal and typical abnormal samples can be differentiated by thickness and roughness parameters during the culture cycle.

The adaptive interface detection algorithm is suitable for high-sensitivity, fast detection, and quantification of the interface with layered characteristic tissues, and can be used for non-destructive detection of the growth regularity of AS sample thickness and roughness during the culture cycle.

Performance of an acousto-optic imaging system is limited by light fluence rate and acoustic pressure field distributions characteristics. In optically scattering media, the former determines the achievable contrast, whereas the latter the imaging resolution. selleck inhibitor The system parameters can be shaped by changing relative positions of ultrasound (US) transducer array and optodes. However, in the case of many potential clinical applications, optimization possibilities in this regard are limited, as a sample is accessible from one side only and using a water tank for coupling is not feasible.

We investigate the possibilities of improving performance of an acousto-optic imaging system operating in reflection mode geometry with linear US array in direct contact with a sample using plane wave instead of focused US pulses.

Differences in acoustic pressure field distributions for various transducer excitation patterns were determined numerically and experimentally. Acousto-optic images of phantoms with and without optically absorbing inclusions were acquired by measuring laser speckle contrast decrease due to the light modulation by plane wave and focused US pulses with different apodization patterns.

The residual acoustic pressure field components occupy relatively large volume and contribute to light modulation. Using nonsteered plane wave US pulses instead of focused ones allows one to mitigate their influence. It also allows one to obtain clear two-dimensional reconstructions of light fluence rate maps by shifting transducer apodization along the lateral direction.

Using nonsteered plane wave US pulses allows one to achieve better imaging performance than with focused pulses in the assumed system geometry.

Polyp size is important for selecting the surveillance interval or treatment policy. Nevertheless, it is challenging to accurately estimate the polyp size during endoscopy. An easy and cost-effective function to assist in polyp size estimation is required.

To propose a virtual scale function for endoscopy and evaluate its performance and expected accuracy.

An adaptive virtual scale behavior was demonstrated. The measurement error of the virtual scale along the distance between the tip of the endoscope and the object plane was evaluated using graph paper. The accuracy of polyp size estimation by an expert endoscopist was compared with the accuracy of the biopsy forceps method using phantom images.

The measurement errors of the virtual scale were   ≤  0.7  mm when the distance to the graph paper, which faced the tip of the endoscope, varied from 4 to 30mm. The accuracy with the virtual scale was significantly higher than that obtained with biopsy forceps (5.3  ±  5.5  %   versus 11.9  ±  9.4  %  , P  <  0.001).

The virtual scale function, which operates in real-time without any additional device, can be used to estimate polyp sizes easily and accurately with endoscopy.

Among dialysis patients, occlusive mesenteric vascular disease has rarely been reported.

To report on the experience of one center with regard to diagnosing and treating this complication.

The retrospective case-series involved six patients (3 females, 3 males; age 52-88 years; 5/6 were smokers) on chronic hemodialysis at a single center. link2 All patients with symptoms suggestive of occlusive mesenteric disease and a subsequent angiographic intervention were included. Demographic, clinical, and laboratory data were collected from patient charts for the period before and after angioplasty and stenting of the mesenteric vessels. A Wilcoxon signed-rank test was used to compare the relevant data before and after the intervention.

All participants had variable co-morbidities and postprandial abdominal pain, food aversion, and weight loss. CT angiography was limited due to heavy vascular calcifications. All underwent angioplasty with stenting of the superior mesenteric artery (4 patients) or the celiac artery (2 patients). All procedures were successful in resolving abdominal pain, malnutrition, and inflammation. Weight loss before was 15 ± 2 kg and weight gain after was 6 ± 2 kg. C-reactive protein decreased from 13.4 ± 5.2 mg/dl to 2.2 ± 0.4 mg/dl (P < 0.05). Serum albumin increased from 3.0 ± 0.2 g/dl to 3.9 ± 0.1 g/dl (P < 0.05). Two patients underwent a repeat procedure (4 years, 5 months, respectively). Follow-up ranged from 0.5-7 years.

Occlusive mesenteric ischemia occurs among dialysis patients. The diagnosis requires a high degree of suspicion, and it is manageable by angiography and stenting of the most involved mesenteric artery.

Limited data exist regarding the safety of ultrasound-guided femoral nerve blockade (US-FNB) in patients with hip fractures treated with anti-Xa direct oral anticoagulants (DOAC).

To compare the safety outcomes of US-FNB to conventional analgesia in patients with hip fractures treated with anti-Xa DOAC.

This observational exploratory prospective study included 69 patients who presented to our emergency department (ED) in 3 years with hip fracture and who were treated with apixaban or rivaroxaban. Patients received either a US-FNB (n=19) or conventional analgesics (n=50) based on their preference and, and the presence of a trained ED physician qualified in performing US-FNB. link3 Patients were observed for major bleeding events during and 30 days after hospitalization. The degree of preoperative pain and opioid use were also observed.

We found no significant difference in the number of major bleeding events between groups (47.4% vs. 54.0%, P = 0.84). Degree of pain measured 3 and 12 hours after presentation was found to be lower in the US-FNB group (median visual analog scale of pain improvement from baseline of -5 vs. -3 (P = 0.002) and -5 vs.-4 (P = 0.023), respectively. Opioid administration pre-surgery was found to be more than three times more common in the conventional analgesia group (26.3% vs.80%, P < 0.0001).

Regarding patients treated with Anti-Xa DOAC, US-FNB was not associated with an increase in major bleeding events compared to conventional analgesia, although it was an effective means of pain alleviation. Larger scale randomized controlled trials are required to determine long-term safety and efficacy.
