Enhanced extracorporeal counterpulsation (EECP) information consists of both text and hemodynamic waveform data. At present EECP text information has been successfully managed through Web browser, while the management and sharing of hemodynamic waveform data through Internet has not been solved yet. In order to manage EECP information completely, based on the in-depth analysis of EECP hemodynamic waveform file of digital imaging and communications in medicine (DICOM) format and its disadvantages in Internet sharing, we proposed the use of the extensible markup language (XML), which is currently the Internet popular data exchange standard, as the storage specification for the sharing of EECP waveform data. Then we designed a web-based sharing system of EECP hemodynamic waveform data via ASP. NET 2.0 platform. Meanwhile, we specifically introduced the four main system function modules and their implement methods, including DICOM to XML conversion module, EECP waveform data management module, retrieval and display of EECP waveform module and the security mechanism of the system.

The development of external counterpulsation (ECP) local area network system and extensible markup language (XML)-based remote ECP medical information system conformable to digital imaging and communications in medicine (DICOM) standard has been improving the digital interchangeablity and sharability of ECP data. However, the therapy process of ECP is a continuous and longtime supervision which builds a mass of waveform data. In order to reduce the storage space and improve the transmission efficiency, the waveform data with the normative format of ECP data files have to be compressed. In this article, we introduced the compression arithmetic of template matching and improved quick fitting of linear approximation distance thresholding (LADT) in combimation with the characters of enhanced external counterpulsation (EECP) waveform signal. The DICOM standard is used as the storage and transmission standard to make our system compatible with hospital information system. According to the rules of transfer syntaxes, we defined private transfer syntax for one-dimensional compressed waveform data and stored EECP data into a DICOM file. Testing result indicates that the compressed and normative data can be correctly transmitted and displayed between EECP workstations in our EECP laboratory.

Objective:To investigate the efficacy and safety of injectable modified sodium hyaluronate gel DX23 in filling and treating midface depression.Methods:A prospective, randomized, multicenter, "no treatment" controlled study was conducted. Patients with midface depression who were treated from March 2019 to February 2021 at Beijing Anzhen Hospital Affiliated to Capital Medical University, Qilu Hospital of Shandong University, and Jining First People’s Hospital were enrolled. Patients were randomized using a stratified block randomization method with a random function list. The experimental group received injectable modified sodium hyaluronate gel DX23 to treat midface depression. The concentration of sodium hyaluronate in DX23 was 23 mg/ml. The syringe was inserted perpendicularly to the skin at a 90-degree angle, and the injection layers were the superficial periosteum or the subcutaneous layer. The injection volume ranged from 1 to 6 ml. The control group received no treatment. The upper boundary of the midface extended outward from the zygomatic arch to the upper margin of the helix and inward to the line connecting the outer canthus. The lower boundary was the line connecting the corner of the mouth to the earlobe. Researchers used the midface aesthetic scales (MAS) response rate at 6 months post-injection as the primary indicator to evaluate the efficacy in improving the severity of midface depression. A reduction of 1 point in the MAS score compared to pre-treatment was considered a response, i. e., effective. Secondary indicators included the MAS response rates at 6 and 12 months after the last treatment (MAS response rate=number of MAS responders/total cases × 100%), the average change in three-dimensional midface volume images, the global aesthetic improvement scale (GAIS) response rate, patient satisfaction regarding the degree of improvement in midface volume, and monitoring of adverse reactions. Data analysis was performed using SPSS 25.0, SAS 9.04, and StataIC 15.0 software. The full analysis set (FAS) and the per-protocol set (PPS) were selected for analysis. Inferential analysis used t-tests and chi-square tests, with P<0.05 considered statistically significant. Results:A total of 164 patients were enrolled. The experimental group included 134 patients (7 males and 127 females) with an average age of 43.0±9.7 years (ranging from 21.6 to 66.6 years). The control group included 30 patients (5 males and 25 females) with an average age of 39.3±11.1 years (ranging from 25.6 to 43.5 years). The experimental group received bilateral midface depression filling, with an initial use of injectable modified sodium hyaluronate gel DX23 at a volume of (4.07±1.28) ml. In the experimental group, 3 cases were lost to follow-up at 30 days, 2 cases at 60 days, and 10 cases were excluded due to protocol violations. Fifteen patients entered FAS but not PPS. Ultimately, 119 patients completed the trial. The MAS response rates in the experimental group at 6 and 12 months post-treatment were 94.96% (113/119) and 56.30% (67/119), respectively. The control group’s MAS response rate at 6 months was 3.33% (1/30). At the 6-month follow-up post-treatment, the GAIS response rates evaluated by researchers and patients in the experimental group were 97.48% (116/119) (PPS) and 97.69% (27/30) (FAS), respectively. In the control group, the GAIS response rate evaluated by researchers was 3.33% (1/30) (FAS, PPS), and the patient GAIS response rate was 0% (0/30) (FAS, PPS). There were statistically significant differences between the two groups in both researcher and patient GAIS response rates (both P<0.01). At 6 months post-injection, comparisons of midface volume changes from baseline between the experimental and control groups showed statistically significant differences [(1.65±1.40) ml (PPS) vs. (0.12±0.85) ml; (1.55±1.44) ml (FAS) vs. (0.12±0.85) ml; both P<0.001]. At the 6-month follow-up in the experimental group, 1 case was lost to follow-up. In the PPS, 81 patients were "satisfied, " 34 were "very satisfied, " and 3 were "neutral." In the control group, 29 patients were "neutral, " and 1 was "dissatisfied." A total of 128 patients in the experimental group experienced injection site reactions, including swelling, hardness, tenderness, pain, lumps (protrusions), and bruising. Over 75% of patients resolved spontaneously within 8 days. Three cases received hot compress treatment and resolved within 28 days. One case experienced swelling of the left lower eyelid 1 day after injection, which resolved after local compression for 3 months. In the control group, 1 case developed circulatory ischemia and carotid atherosclerosis 12 months after the trial began. Conclusion:Injectable modified sodium hyaluronate gel DX23 corrects midface depression through local volume augmentation and is characterized by safety and durability.

Parthenogenetic embryonic stem (pES) cells isolated from parthenogenetic activation of oocytes and embryos, also called parthenogenetically induced pluripotent stem cells, exhibit pluripotency evidenced by both in vitro and in vivo differentiation potential. Differential proteomic analysis was performed using differential in-gel electrophoresis and isotope-coded affinity tag-based quantitative proteomics to investigate the molecular mechanisms underlying the developmental pluripotency of pES cells and to compare the protein expression of pES cells generated from either the in vivo-matured ovulated (IVO) oocytes or from the in vitro-matured (IVM) oocytes with that of fertilized embryonic stem (fES) cells derived from fertilized embryos. A total of 76 proteins were upregulated and 16 proteins were downregulated in the IVM pES cells, whereas 91 proteins were upregulated and 9 were downregulated in the IVO pES cells based on a minimal 1.5-fold change as the cutoff value. No distinct pathways were found in the differentially expressed proteins except for those involved in metabolism and physiological processes. Notably, no differences were found in the protein expression of imprinted genes between the pES and fES cells, suggesting that genomic imprinting can be corrected in the pES cells at least at the early passages. The germline competent IVM pES cells may be applicable for germ cell renewal in aging ovaries if oocytes are retrieved at a younger age.
