Abstract
(1) Objectives: This study aimed to compare a collagen matrix to a hemostatic gelatin sponge as a socket seal in alveolar ridge preservation (ARP). (2) Methods: Systemically healthy patients planned for ARP at two sites with more than 50% of the buccal bone wall remaining after tooth extraction were eligible for inclusion. ARP involved socket grafting using collagen-enriched deproteinized bovine bone mineral. Sites were then randomly assigned to the test group (collagen matrix) or the control group (hemostatic gelatin sponge). The primary outcome was soft tissue thickness in the center of the site at 4 months, analyzed on cone-beam computed tomography. Secondary outcomes included the buccal and lingual soft tissue heights, horizontal bone loss, buccal soft tissue profile changes, wound dimensions, and Socket Wound Healing Score (SWHS). (3) Results: In total, 18 patients (12 females, 6 males) with a mean age of 57.3 years (SD 11.1) were included. Four months after ARP, the soft tissue thickness in the center of the site amounted to 2.48 mm (SD 0.70) in the test group and 1.81 mm (SD 0.69) in the control group. The difference of 0.67 mm (95% CI: 0.20-1.14) in favor of the collagen matrix was statistically significant (p < 0.009). The buccal soft tissue height was also statistically significantly higher for the collagen matrix (0.72 mm; 95% CI: 0.06-1.38; p = 0.034). A trend favoring the collagen matrix was found for the lingual soft tissue height (p = 0.066). No significant differences between the groups in terms of horizontal bone loss, buccal soft tissue profile changes, wound dimensions, and the SWHS were found. (4) Conclusions: The absence of significant differences in hard tissue outcomes suggests that both the collagen matrix and hemostatic gelatin sponge effectively sealed the extraction socket and supported bone preservation. However, the collagen matrix better maintained soft tissue dimensions. The clinical relevance of this finding with respect to the necessity for adjunctive soft tissue augmentation at the time of implant placement is yet to be studied.

Abstract
OBJECTIVE To determine if absorbable gelatin sponge (AGS) can be used to assess the posttympanoplasty microbiome and otic antibiotic exposure. STUDY DESIGN Prospective. SETTING Tertiary hospital. METHODS Patients undergoing tympanoplasty were prospectively enrolled. Intraoperatively, AGS was applied to the medial ear canal/tympanic membrane (TM) for 1 minute after canal incision, then saved for analysis. Ear canals were packed with AGS at the end of surgery. Otic ofloxacin was administered until the first postoperative visit, when AGS was collected. Microbial presence was assessed by culture. Ofloxacin levels were assessed by liquid-chromatography mass-spectrometry. RESULTS Fifty-three patients were included. AGS was collected in 92.9% of patients seen within 21 days compared to 70.8% of those seen at 22 to 35 days. At surgery, AGS yielded bacteria and fungi in 81% and 11%, respectively, including Staphylococcus species (55%) and Pseudomonas species (25%). Postoperatively, AGS yielded bacteria in 71% and fungi in 21% at the meatus, (staphylococci 57% and pseudomonas 25%). TM samples yielded bacteria in 69%, fungi in 6%, staphylococci in 53%, and pseudomonas in 19%. Ofloxacin concentration at the meatus was 248 μg/mL (95% confidence interval [CI]: 119-377) and at the TM was 126 μg/mL (95% CI: 58-194). Ofloxacin-resistant colonies were found in 75% of patients. CONCLUSION Analysis of AGS is a viable technique for noninvasively studying healing metrics posttympanoplasty, including the microbiome and otic antibiotic exposure. Despite exposure to a high concentration of quinolones, the tympanoplasty wound is far from sterile, which may impact healing outcomes.

Abstract
Apart from the wide and safe application of natural polymer-based hemostatic materials/devices, it is still desirable to develop new types of hemostatic materials that can achieve both potent coagulopathic hemostasis and a facile preparation process. In this work, one Janus gelatin sponge (J-ZGS) is readily constructed for both coagulation-dependent and coagulopathic hemostasis by embedding zein nanoparticles on the surface of a self-prepared gelatin sponge (S-GS): zein nanoparticles were facilely prepared by an antisolvent method to achieve procoagulant blood-material interactions, while S-GS was prepared by freeze-drying a foaming gelatin solution. Due to the distinct secondary structure, the optimal zein nanoparticles possessed a higher in vitro hemostatic property than the pristine zein powder and other nanoparticles, the underlying mechanism of which was revealed as the superior RBC/platelet adhesion property in the presence/absence of plasma proteins. Compared with S-GS and a commercial gelatin sponge, J-ZGS achieved a significantly higher in vitro hemostatic property and similarly good blood compatibility/cytocompatibility. Moreover, in vivo artery-injury models confirmed the outstanding hemostatic performance of J-ZGS under both coagulation-dependent and coagulopathic conditions. Our work offers an appealing approach for developing potent hemostatic sponges from natural polymer-based nanoparticles that could be further extended to versatile hemostatic materials for coagulopathic hemostasis.

Abstract
Background and Aim Transcatheter arterial chemoembolization (TACE) using various anticancer drugs is often performed to treat hepatocellular carcinoma (HCC). We aimed to compare the therapeutic efficacy and side effects of TACE with anticancer drugs versus transcatheter arterial embolization (TAE) without anticancer drugs for HCC. Methods Patients with HCC were randomized to either the TACE or TAE group. Up to five target nodules were treated in each patient. Lipiodol (Lp; 10 mL), contrast media (CM; 10 mL), epirubicin (40 mg), mitomycin C (10 mg), miliplatin (70 mg), and 1-2-mm 2-day soluble gelatin sponge particles (2D-SGS) were injected into the TACE group, whereas Lp (10 mL), CM (10 mL), and 2D-SGS were injected into the TAE group. Treatment effect (TE) of the target nodules was graded (TE1-TE4) and patient responses were assessed. Three months after treatment, blood tests were performed to compare tumor markers and adverse events. Results Fifty-four patients and 161 target nodules were included; 75 nodules in 28 patients were treated by TACE, and 86 nodules in 26 patients were treated by TAE. The number of nodules graded TE1, TE2, TE3, and TE4 was 1, 28, 7, and 39, respectively, in the TACE group and 2, 25, 7, and 52, respectively, in the TAE group. The response rates were 89% (25/28) and 73% (19/26) in the TACE and TAE groups, respectively. There were no significant differences in TE, response rates, or blood test results between the two groups. Conclusion In hepatic arterial embolization for HCC, anticancer drugs did not have any impact on the therapeutic efficacy or side effects at 3 months after embolization.

Abstract
The purpose of this study was to report the effectiveness of preoperative transcatheter arterial embolization (TAE) of musculoskeletal tumors in terms of blood loss and functional outcomes. Patients who underwent preoperative TAE of hypervascular musculoskeletal tumors between January 2018 and December 2021 were retrospectively included. The patients' characteristics, TAE procedure details, degree of post-TAE devascularization, surgical outcomes in terms of red blood cell transfusion and functional results were collected. The degree of devascularization was compared between patients who had peri-operative transfusion and those who did not. Thirty-one patients were included. The 31 TAE procedures led to complete (58%) or near-complete (42%) tumor devascularization. Twenty-two patients (71%) had no blood transfusion during surgery. Nine patients (29%) had a blood transfusion, with a median number of red blood cell packs of three (q1, 2; q3, 4; range: 1-4). Eight patients (27%) had complete improvement of the initial musculoskeletal symptoms at the end of the follow-up, 15 (50%) had partially satisfying improvement, 4 (13%) had partially unsatisfying improvement and 3 (10%) had no improvement. Our study suggests that preoperative TAE of hypervascular musculoskeletal tumors allowed for bloodless surgery in 71% of patients and minimal transfusion needs for the remaining 29%.

Abstract
BACKGROUND Postpartum hemorrhage is the leading cause of maternal mortality in emerging countries. This study aims to evaluate the effectiveness and safety of uterine artery embolization (UAE) using suture fragment (FairEmbo concept) in a swine model. METHODS Seven female swine uteri were embolized. The left uterine artery was embolized with 1 cm fragments of absorbable suture (Optime® 0), and with gelatin sponge torpedoes for the contralateral side for comparison. The embolization effectiveness and the time for arterial recanalization with digital subtraction angiography (DSA) controls at D0, D7, and M1, were evaluated. Follow-up protocol also included clinical monitoring and macroscopical analyses at M1. A Mann-Whitney test (significance at P 0.05) was used for statistics. RESULTS A technical success was obtained for the seven arteries on each side, with no off-target embolization. The procedure time (10 min versus 3.7 min) and number of fragments (13.8 versus 5.7) required for complete occlusion were significantly greater in the FairEmbo group. All arteries were repermeabilized at M1. No necrosis was macroscopically visible at harvest at M1. CONCLUSION This experimental study suggests that UAE with SBM FairEmbo method is feasible, safe, and effective in comparison with gelatin sponge procedure.

Abstract
PURPOSE To determine the effects of tract embolization with gelatin sponge particles on the prevention of pneumothorax after percutaneous microwave ablation (MWA) in rabbit lungs. MATERIALS AND METHODS Twenty-four New Zealand white rabbits were randomly divided into Group A (MWA followed by tract embolization with gelatin sponge particles, n = 12) and Group B (MWA without tract embolization, n = 12). For each group, CT images were reviewed for the occurrence of pneumothorax within 30 min after MWA. The rate of pneumothorax was compared by Chi-square Test. Lung tissue around the needle tract was harvested after the rabbits were euthanized, and histopathological examinations were performed and studied with hematoxylin and eosin stains. RESULTS Twenty-four animals underwent 47 sessions of MWA (24 sessions in Group A and 23 sessions in Group B). Group A had a statistically lower rate of pneumothorax than Group B (25.0 vs. 56.5%; p = 0.028). The pathological examinations of both groups demonstrated thermal injury of the needle tract characterized by a rim of the coagulated lung parenchyma, which might be responsible for pneumothorax after MWA. Gelatin sponge particles could be arranged in irregular flakes densely to effectively seal the needle tract, thus reducing the occurrence of pneumothorax. The gelatin sponge particles could be almost completely absorbed about 14 days later. CONCLUSION Results of the present study showed needle tract embolization with gelatin sponge particles after CT-guided pulmonary MWA can significantly reduce the incidence of pneumothorax. Gelatin sponge particles can effectively seal the needle tract after ablation and can be completely absorbed in the body with good safety.

Abstract
Introduction Several articles have investigated the intra-alveolar applications of bioadhesive gels containing various medicines and active chemicals, such as chlorhexidine (CHX) and hyaluronic acid (HA) to minimize the numerous postoperative sequelae, such as a dry socket. The purpose of this study was to investigate the postoperative outcomes of intra-alveolar application of 0.2% chlorhexidine or hyaluronic acid following atraumatic extraction. Methods A randomized clinical trial was conducted on a sample of 36 patients who need extraction of lower first premolar for orthodontic treatment. The patients were assigned randomly into two groups: CHX group and HA group. The signs and symptoms of the dry socket were evaluated on the third day in two groups. Results There was no statistically significant difference between the study and control groups when comparing the CHX group (P=0.2.6). In contrast, a significant difference was seen between the study and control sides in the HA group. Conclusions Within the limitation of this clinical trial, using hyaluronic gel with a gelatin sponge may be a preventive strategy for a dry socket following tooth extraction. After non-surgical tooth extraction, the topical administration of CHX with a gelatin sponge as a carrier did not seem to act as a protective substance against a dry socket.

Abstract
Purpose This study aimed to compare the clinical efficacy and prognostic analysis results of 8spheres polyvinyl alcohol (PVA) microspheres (8SM) with gelatin sponge (GS) particles for transcatheter arterial chemoembolization (TACE) in patients with stages A-B hepatocellular carcinoma (HCC). Methods Data were collected from 172 patients who underwent TACE at Harbin Medical University Cancer Hospital from January 2014 to July 2020. Patients were divided into two groups: TACE group using 8SM plus lipiodol (8spheres PVA group, N = 89) and TACE group using GS particles plus lipiodol (the GS group, N = 83). Subsequently, we compared the liver function, blood count, alpha-fetoprotein (AFP), and other parameters of patients in each group before and after interventional embolization. We also calculated the patient's progression-free survival and overall survival in these groups. Results The postoperative liver function indices, such as alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in the 8spheres PVA group, were worse than in the GS group. The postoperative median survival time was 19 ± 3.06 months and no significant difference in survival time was observed in GS group (26 ± 3.19 months) (P = 0.509). Multivariate analysis showed that targeted therapy (P = 0.051), maximum tumor diameter <5 cm (P = 0.018), age ≥60 years (P = 0.018), and AFP <120.5 μg/L (P = 0.007) significantly improved the overall survival rate of patients. Conclusion Postoperative liver function indices of patients with HCC treated with GS particles were better than those treated with 8SM; thus, GS particles are more suitable for patients with poor liver function.

Abstract
Percutaneous transhepatic venous access has been utilised for numerous transcatheter cardiac procedures. Traditionally, a large transhepatic tract requires the placement of permanent occlusion devices or coils. We describe a successful closure using a simple technique (Surgifoam) without the need for metal hardware placement. Immediate hemostasis was achieved. No complications were encountered.

Abstract
Introduction: To evaluate the efficacy, safety, and associated complications of a novel and simple approach to portal vein embolization that utilizes sheath injection and balloon occlusion (PVE-SIBO) with gelatin sponge (GS) for the purpose of increasing future liver remnant (FLR) volume. Methods: Between 1 January, 2006, and 31 August, 2020, 20 patients (15 men, 5 women, aged 64.6 ± 10.2 years) diagnosed with hepatobiliary malignancy underwent presurgical PVE-SIBO at our institution via a percutaneous transhepatic approach to the right portal vein and embolization of the portal vein with GS. We evaluated the increased ratio of FLR volume, operation duration, recanalization rate, and complications following this procedure. Results: All procedures were successful and without complications such as subcapsular hematoma, intra-abdominal bleeding, and bile leakage. The increased ratio of FLR volume was 34.7 ± 23.7% after a mean of 14.3 ± 2.57 days, and there was a significant difference in the FLR volume before and after PVE (P < 0.01). Procedure time was 52.7 ± 11.4 minutes. Conclusion: PVE-SIBO with GS is a simple, effective, and safe procedure to increase the ratio of FLR volume prior to hepatic surgeries.

Abstract
BACKGROUND Compared to two-dimensional cultures, three-dimensional (3D) cultures have many advantages in cancer studies. Nevertheless, their implementation is unsatisfactory. This study aimed to develop an anchorage-dependent 3D culture model for colorectal cancer research. MATERIALS AND METHODS Human HCT116, DLD-1 and SW620 colorectal cell lines were cultured in a gelatin sponge, and its applicability for morphological examination was studied. RESULTS The resulting specimens were suitable for scanning electron microscopy, transmission electron microscopy, and immunohistochemical examination. HCT116 formed smaller structures and migrated through the pores of the sponge. DLD-1 formed larger structures with tight cell-to-cell adhesion. SW620 also formed large structures but small clustered cells tended to attach to the anchorage more favorably. Immunohistochemical staining demonstrated phosphorylated yes-associated protein (YAP) localized near the attachment site in HCT116 cells. CONCLUSION Because the gelatin sponge provided suitable anchorage and the cultured cells formed distinguishable 3D structures, this method may be useful for further colorectal cancer research.

Abstract
INTRODUCTION Computed tomography (CT)-guided lung biopsy is a frequently performed procedure in the diagnostic workup for suspicious lung nodules that can be complicated by pneumothorax. This retrospective study assessed the efficacy of biopsy tract occlusion with a gelatin sponge slurry for preventing post-biopsy pneumothorax. METHODS Retrospective analysis was conducted on consecutive adult patients who underwent CT-guided lung biopsy over a 10-year period. Age, gender, existing chronic obstructive pulmonary disease (COPD), evidence of emphysema on CT, location of the lesion and the presence of pneumothorax on post-procedure CT and 4-h chest radiograph were recorded. RESULTS Two hundred and ninety-six patients were included (126 patients in the non-gelfoam group and 170 in the gelfoam group). When gelfoam was used, risk of developing an immediate pneumothorax was lower (P = 0.032). Patients with emphysema were 2.4 times more likely to develop a delayed pneumothorax without gelfoam (P = 0.034). There was a significantly higher risk of both immediate and delayed pneumothorax in non-peripheral lesions without gelfoam (P = 0.001 and P = 0.002, respectively). The frequency of requiring a chest tube to treat a pneumothorax was 86% lower when gelfoam was used (P = 0.012). CONCLUSION Gelfoam is effective in preventing immediate pneumothorax. In patients with emphysema, there was a significantly higher risk of delayed pneumothorax without gelfoam. Additionally, non-peripheral lesions were more likely to develop pneumothorax when gelfoam was not used. The use of gelfoam was especially important in preventing the development of major pneumothoraces that would require drainage with a chest tube.

Abstract
BACKGROUND Human umbilical cord mesenchymal stem cells (HuMSCs) injected directly have been proven effective for improving chronic wounds. However, HuMSCs largely die within 14 days. The aim of study is to establish a cellularly modified gelatin sponge and investigate its characteristics and clinical potential. METHODS HuMSCs were isolated, expanded and seeded in a poly-L-lysine (PLL)-coated gelatin sponge. Fabricated gelatin sponges were estimated through observation of morphological surface and ultrastructure, following confirmed by histology method. Supernatants were collected at different times for enzyme-linked immunosorbent assays (ELISAs) to measure growth factors. The cell embedded gelatin sponges were implanted subcutaneously on the backs of mice and the samples were harvested and studied histologically. RESULTS HuMSCs gradually modified the gelatin sponge by depositing collagen and hyaluronic acid, and degrading the structure of gelatin, resulting in a dense, and elastic structure. Compared with cells cultured in monolayer, the levels of growth factors increased remarkably when HuMSCs were cultivated in the gelatin sponge. Upon subcutaneous implantation in the backs of mice, the cellularized gelatin sponges persisted for up to 2 months and eventually integrated into the host tissue, while blank gelatin sponges degraded completely by the end of the second month. CONCLUSION Gelatin sponge is a clinically accessible scaffold for HuMSCs implantation to maintain short-term survival of the cells and high-level production of growth factors, which demonstrates good clinical potential for enhancing wound healing.

Abstract
Gelatin possesses biological properties that resemble native skin and can potentially be fabricated as a skin substitute for full-thickness wound treatment. The native property of gelatin, whereby it is easily melted and degraded at body temperature, could prevent its biofunctionality for various applications. This study aimed to fabricate and characterise buffalo gelatin (Infanca halal certified) crosslinked with chemical type crosslinker (genipin and genipin fortified with EDC) and physicaly crosslink using the dihydrothermal (DHT) method. A porous gelatin sponge (GS) was fabricated by a freeze-drying process followed by a complete crosslinking via chemical—natural and synthetic—or physical intervention using genipin (GNP), 1-ethyl-3-(3-dimethylaminopropyl) (EDC) and dihydrothermal (DHT) methods, respectively. The physicochemical, biomechanical, cellular biocompatibility and cell-biomaterial interaction of GS towards human epidermal keratinocytes (HEK) and dermal fibroblasts (HDF) were evaluated. Results showed that GS had a uniform porous structure with pore size ranging between 60 and 200 µm with high porosity (>78.6 ± 4.1%), high wettability (<72.2 ± 7.0°), high tensile strain (>13.65 ± 1.10%) and 14 h of degradation rate. An increase in the concentration and double-crosslinking approach demonstrated an increment in the crosslinking degree, enzymatic hydrolysis resistance, thermal stability, porosity, wettability and mechanical strength. The GS can be tuned differently from the control by approaching the GS via a different crosslinking strategy. However, a decreasing trend was observed in the pore size, water retention and water absorption ability. Crosslinking with DHT resulted in large pore sizes (85–300 µm) and low water retention (236.9 ± 18.7 g/m2·day) and a comparable swelling ratio with the control (89.6 ± 7.1%). Moreover no changes in the chemical content and amorphous phase identification were observed. The HEK and HDF revealed slight toxicity with double crosslinking. HEK and HDF attachment and proliferation remain similar to each crosslinking approach. Immunogenicity was observed to be higher in the double-crosslinking compared to the single-crosslinking intervention. The fabricated GS demonstrated a dynamic potential to be tailored according to wound types by manipulating the crosslinking intervention.

Abstract
An effective and viable hemostatic agent is important for stopping bleeding during surgery. However, it is difficult to achieve hemostasis at uneven or deep bleeding sites using a gelatin sponge. A flowable hemostatic agent has therefore been developed by processing and improving gelatin sponge, to address bleeding under these conditions. In this study, we evaluated the efficacy, safety, and physical and chemical properties of this flowable hemostatic agent in various experiments. We examined its efficacy for stopping bleeding in a rabbit model of liver abrasion in vivo, and compared its efficacy in dynamic coagulation and erythrocyte aggregation tests with gelatin sponge in vitro. We also investigated its safety in rat histocompatibility and acute systemic toxicity tests in mice in vivo, and in hemolysis tests in vitro, to determine if the flowable hemostatic agent induced any pathological reactions or adverse events. In terms of its physical and chemical properties, we analyzed the morphology and chemical bonds of the flowable hemostatic agent by optical and electron microscopy and infrared spectroscopy, and its absorbency and density. The flowable hemostatic agent resulted in a shorter mean bleeding time, less bleeding, greater likelihood of successful hemostasis, and reduced clotting time compared with gelatin sponge. The flowable agent produced some changes in physical morphology, but no pathological changes or undesirable outcomes were detected. This flowable topical hemostatic agent thus provides a safe and more effective hemostatic method than gelatin sponge, and more promising results for intraoperative hemostasis, especially on uneven or deep bleeding surfaces.

Abstract
Objective:The aim of this study is to explore the preventive and therapeutic effects of gelatin sponge on the occurrence and development of chylous leakage by combining the biological characteristics of gelatin sponge with the mechanism of left neck lymph node dissection. Method: Eight hundred and twenty-eight patients who underwent left neck lymph node dissection in our department were retrospectively analyzed, 568 of whom underwent routine chylous leakage prevention and treatment (group A), 260 underwent gelatin sponge tamponade fixation. The prevention and treatment of chyle leakage (group B) were analyzed. Result:Twenty-six cases of chyle leakage occurred in group A and 8 cases of chyle leakage occurred in group B. The incidence of chyle leakage in group B (3.1%) was not significantly different from that in group A (4.6%). However, the incidence of chyle leakage within three days after operation was better than that in group A, and the amount of chyle leakage was significantly less than that in group A. The time of improving chylous leakage by positive pressure bandaging was better than that of group A, with statistical significance. Conclusion:Gelatin sponge packing can not reduce the occurrence of chyle leakage, but can delay the occurrence time of chyle leakage and reduce the amount of chyle leakage. It has a certain clinical value in the active treatment of chyle leakage.

Abstract
Periodontal plastic surgery often involves palatal donor site, thereby creating an open wound that is prone to postoperative complications such as bleeding, pain, and slow healing process. To prevent the same, platelet-rich fibrin (PRF) and gelatin sponge (GS) were utilized equally at the donor site in six patients. Patients were monitored at the 1st, 2nd, 3rd, and 4th weeks after surgery for postoperative discomfort (D), consumption of analgesics during first postoperative week, alteration of sensitivity (AS), change in feeding habits (CFH), complete wound epithelialization (CWE), and healing index (Landry et al. 1998). Two patients in the GS group showed significantly early CWE, higher healing index score, and less D, AS, and CFH postoperatively in comparison to the PRF group. It was suggested that GS can also be considered as an effective, economical, and biocompatible dressing material of choice to enhance wound healing and to minimize postoperative complications associated with the donor site.

Abstract
Purpose: To evaluate the usefulness of preoperative transcatheter arterial embolization using a gelatin sponge for hypervascular head and neck tumors to reduce intraoperative blood loss (IBL). Material and methods: Nineteen patients underwent preoperative transcatheter arterial embolization for hypervascular head and neck tumors using a gelatin sponge. The technical success rate, devascularization rate, IBL, and complications were evaluated. Angiography images obtained before and after preoperative embolization were compared in all patients, and the devascularization rate was assessed from the relative reduction rate of contrast agent volumes. Results: The technical success rate was 100%. The median devascularization rate was 95% (range, 75-100%). The median period between embolization and surgical resection was one day (range, 1-12 days). The median IBL was 122 ml (range, 0-3780 ml). Blood transfusions were required in three cases, and their IBL and devascularization rates were 850, 1959, and 3780 ml, and 75%, 90%, and 80%, respectively. There was a complication of cerebral embolism in one out of 19 cases (5%). Conclusions: Preoperative transcatheter arterial embolization using a gelatin sponge was feasible and may contribute to decreasing IBL.

Abstract
Dental pulp stem cell is a new type of mesenchymal stem cell that has a potential for tissue regeneration. Gelatin sponges are often used for hemostasis in dental surgery. In this study, we aimed to evaluate the dental pulp stem cells' proliferation and osteogenic differentiation in different layer-by-layer-modified gelatin sponge scaffolds including the G, G + P (gelatin sponge+ poly-l-lysine modification), G + M (gelatin sponge + mineralization modification), and G + M + P (gelatin sponge + mineralization modification + poly-l-lysine modification) groups in vitro and assessed them in vivo. The results showed that dental pulp stem cells had a great potential for osteogenic differentiation. In vitro, the G + M + P group not only enhanced the adhesion and proliferation of dental pulp stem cells but also facilitated their osteogenic differentiation. However, alkaline phosphatase activity was prohibited after modification. In vivo, both dental pulp stem cells and cells from nude mice grew well on the scaffold, and G + M and G + M + P groups could promote the mineralization deposit formation and the expression of osteocalcin in osteogenic differentiation of dental pulp stem cells. In conclusion, the combination of dental pulp stem cells and G + M + P scaffold has a great potential for bone tissue engineering.

OBJECTIVE To compare the outcomes of epidermal growth factor (EGF) and gelatin sponge patch treatments for traumatic tympanic membrane perforations. STUDY DESIGN Prospective, randomized, controlled. SETTING University-affiliated teaching hospital. SUBJECTS AND METHODS In total, 141 perforations encompassing >50% of the eardrum were randomly divided into 3 groups: EGF (n = 47), gelatin sponge patch (n = 47), and observation (n = 47). The edges of the perforations were not approximated. The closure rate, mean closure time, and infection rate were evaluated at 6 months and the related factors analyzed. RESULTS A total of 135 perforations were analyzed. At 6 months, the closure rates were 97.8%, 86.7%, and 82.2% in the EGF, gelatin sponge patch, and spontaneous healing groups, respectively (P = .054). The mean ± SD closure time was 11.12 ± 4.60, 13.67 ± 5.37, and 25.65 ± 13.32 days in the EGF, gelatin sponge patch, and spontaneous healing groups, respectively (P < .001). In addition, the presence of infection was not significantly associated with rate of closure in any group. CONCLUSIONS As compared with spontaneous healing, daily application of EGF and gelatin sponge patching reduced the closure time of traumatic tympanic membrane perforations. EGF treatment had a higher closure rate and shorter closure time but resulted in otorrhea. By contrast, gelatin sponge patches did not improve the closure rate or cause otorrhea but required repeated patch removal and reapplication. Thus, the appropriate treatment should be selected according to patient need.

Abstract
The hepatic VX2 carcinoma model in rabbits is widely used for the preclinical study of hepatocellular carcinoma. In the present study, a modification was made to the conventional method to establish the animal model, as the conventional method gives rise to frequent tumor seeding due to the drop-out of tumor fragments. In order to evaluate each distinct method of establishing the model, the rabbits were divided into two groups: Group A (the conventional method; n=20) and group B (the modified method; n=20). All surgical details were recorded for reference. At 14 days post-surgery, contrast-enhanced computed tomography (CECT) and autopsy were conducted. Microscopic morphology of tumor cells was observed using hematoxylin and eosin (H&E) and transmission electron microscopy (TEM). Vascular endothelial growth factor (VEGF) and cluster of differentiation (CD)31 were detected via immunochemistry and reverse transcription-polymerase chain reaction. In total, 19 rabbits in each group succeeded in model establishment. Throughout the surgery, group A experienced a longer surgery time compared with group B (group A vs. group B, 22.57±1.34 vs. 20.17±1.50 min; P<0.001), an increased tumor fragment drop-out frequency (group A vs. group B, 1.84±0.96 vs. 1.16±0.38; P=0.008) and an increased peritoneal nodule incidence (group A vs. group B, 35 vs. 5%, P=0.042). As for CECT, H&E and TEM, hepatic VX2 allografts in the two groups demonstrated similar imaging presentations and tumor cell morphology. In addition, VEGF and CD31 levels did not differ between the two groups. In conclusion, the modified method for the establishment of hepatic VX2 carcinoma model in rabbits may decrease tumor fragment drop-out frequency during surgery and incidence of tumor seeding without affecting the properties of VX2 carcinoma.

Abstract
OBJECTIVE To explore the role and mechanism of drug delivery systems using growth factor combined with gelatin sponge on accelerating the healing of jaw fracture and to seek better treatment of accelerating the maxillofacial fracture. METHODS About 100 μg recombinant human bone morphogenetic protein (BMP)-2 was completely dissolved in 1 mL recombinant bovine basic fibroblast growth factor (bFGF), and the solution (40 μL) was dropped in gelatin sponge (0.5 cm×0.5 cm×1.0 cm). Then, it was freeze dried and prepared into bFGF/BMP/gelatin sponge delivery systems. The mandibular fracture model on two sides were prepared in 12 New Zealand rabbits and randomly divided into two groups. The left side was the control group, which was only fixed with titanium plates. The right side was the experimental group, in which bFGF/BMP/gelatin sponge delivery systems were put under the titanium plates. General observation, X-ray, and histological examination were taken at 2, 4, and 12 weeks after surgery. RESULTS After 2 weeks, more fibrous tissues were seen between the fracture ends in the experimental group than in the control group. After 4 weeks, fibrous fracture callus were seen in the fracture gap in the experimental group. The ingrowths of fibrous tissue and blood vessels were seen in the control group. The fracture healing of the experimental group was significantly faster than the control group at 2 and 4 weeks. After 12 weeks, the experimental and control groups all healed completely. CONCLUSIONS bFGF/BMP/gelatin sponge can accelerate and improve fracture healing; thus, it has better clinical application prospect.

Abstract
OBJECTIVE The purpose of this study was to compare the efficacy and safety of microfibrillar collagen paste with those of gelatin sponge for liver track embolization after islet cell transplants. MATERIALS AND METHODS In a single-institution, retrospective study, 37 patients underwent 66 islet cell transplants from January 2005 through October 2015. Transplants were performed with 6-French transhepatic access, systemic anticoagulation, pretransplant and posttransplant portal venous pressure measurement, and image-guided liver track embolization with gelatin sponge (2005-2011) or microfibrillar collagen paste (2012-2015). The findings on 20 patients (two men, 18 women; mean age, 48 years) who underwent 35 gelatin sponge embolizations were compared with the findings on 13 patients (six men, seven women; mean age, 48 years) who underwent 22 microfibrillar collagen paste embolizations (four patients, nine procedures without embolization excluded). Medical record review was used to compare laboratory test results, portal venous pressures, and 30-day adverse bleeding events (classified according to Society of Interventional Radiology and Bleeding Academic Research Consortium criteria) between groups. RESULTS The technical success rates were 100% in the microfibrillar collagen paste group and 91% in the gelatin sponge group. Group characteristics were similar, there being no differences in platelet count, partial thromboplastin time, or number of islet cell transplants per patient (p > 0.05). A statistical difference in international normalized ratio (1.0 versus 1.1) was not clinically significant (p = 0.012). Posttransplant portal venous pressure was slightly higher among patients treated with gelatin sponge (13 versus 9 mm Hg, p = 0.002). No bleeding occurred after microfibrillar collagen paste embolization, whereas nine bleeding events followed gelatin sponge embolization (0% versus 26%, p = 0.020). In univariate comparison of bleeding and nonbleeding groups, the use of gelatin sponge was statistically associated with postprocedure hemorrhage. CONCLUSION Microfibrillar collagen paste is effective and safe for liver track embolization to prevent bleeding after islet cell transplants. It appears to be more efficacious than gelatin sponge.

Abstract
AIM The aim of this study was to compare the therapeutic efficacy of transcatheter arterial embolization (TAE) with gelatin sponge (GS) and polyvinyl alcohol (PVA) particles for cesarean scar pregnancy (CSP). METHODS A total of 35 patients with CSP, who were classified into either the GS group (n = 22) or the PVA group (n = 13), underwent TAE and postoperative ultrasound-guided curettage. Their hospital stay, first-scheme success rate, intra-curettage blood loss, serum β-human chorionic gonadotropin (hCG) level, and other indicators were simultaneously recorded. During the follow-up period, time for the serum β-hCG level to return to normal, time for the return of menstrual cycle, and menstrual blood volume were recorded. RESULTS Compared with the GS group, patients in the PVA group: (i) were older; (ii) had greater number of abortions or curettages, and had longer times since last cesarean (P < 0.05); (iii) had similar hospital stay and first-scheme success rate (P > 0.05); (iv) had lower, but not significantly different, hemorrhage rate (7.7% vs 36.4%, P = 0.066); (v) had a significantly higher serum β-hCG level at discharge and a smaller drop in serum β-hCG level from admission to discharge (P < 0.05); (vi) had a similar time for the serum β-hCG level to return to normal (P > 0.05); (vii) had a shorter time for the return of menstrual cycle (P = 0.012); and (viii) had a significantly higher incidence of abnormal menstrual blood volume reduction (50.0% vs 8.3%, P = 0.034). CONCLUSION TAE with either GS or PVA particles for CSP treatment had relatively good efficacy. During the selection of the ideal embolic agent, the patient's age, hemorrhage risk, and requirement for protecting ovarian function and reserving fertility should be comprehensively considered.

Abstract
AIM The aim of this study was to retrospectively analyze the efficacies of uterine artery embolization (UAE) using gelatin sponge for symptomatic uterine fibroids. METHODS A series of 60 consecutive premenopausal women underwent UAE using gelatin sponge particles or porous gelatin particles. Patients were routinely followed up at 1, 3, 6, and 12 months after the procedure and asked to report any procedure-related complications. At each follow-up, an original clinical questionnaire was completed by the patients to evaluate changes in fibroid-related symptoms. Pelvic magnetic resonance imaging was performed before and at 3 and 12 months after the procedure, and the changes in volume of the dominant fibroid were calculated. RESULTS Bilateral UAE was successfully performed in all the patients. Median age was 45 years (range 34-53 years), and median follow-up period was 25.2 months (range 1-116 months). At the 3- and 12-month follow-up, the dominant fibroid volumes were found to be significantly decreased by 33.4% (95% confidence interval [CI]: 24.9-41.1) and 48.4% (95% CI: 40.7-56.1) compared to baseline volumes, respectively. Excluding patients not having menorrhagia or bulk-related symptoms, at 12 months 49 of 50 (98%) women showed improvement in menorrhagia, and 45 of 47 (95.7%) women showed improvement in bulk-related symptoms. During the follow-up period, ten patients (16.7%) required further interventions including two patients who had undergone hysterectomy. No sequelae were experienced by any of the patients. CONCLUSION UAE using gelatin sponge was associated with a high clinical success rate and good fibroid volume reduction compared to UAE using other embolic agents.

Abstract
BACKGROUND Preoperative transcatheter arterial embolization for hypervascular bone and soft tissue tumors plays an important role in reducing intraoperative blood loss (IBL). PURPOSE To evaluate the use of a gelatin sponge in preoperative transcatheter arterial embolization for hypervascular bone and soft tissue tumors in the pelvis or extremities. MATERIAL AND METHODS Thirty-seven patients (21 men, 16 women; median age, 61 years; age range, 23-79 years) underwent preoperative transcatheter arterial embolization between April 2004 and January 2015. Medical records and images were reviewed, and the technical success rate, clinical success rate, and complications were evaluated. Technical success was defined as a devascularization rate of 75% or higher, and clinical success was defined as intraoperative blood loss (IBL) <1500 mL in cases undergoing surgery within 3 days of transarterial embolization and <3000 mL in cases operated 4 or more days later. RESULTS Tumor sizes were in the range of 2.0-13.0 cm (median, 5.0 cm). The devascularization rate was decreased by >75% at follow-up angiography in all cases, and the technical success rate was 100 % (37/37). The median IBL was 491 mL (range, 30-3800 mL), and the clinical success rate was 89% (33/37). The minor complication of local pain was observed in 13 out of 37 cases (35%) during or after embolization, but was controllable by an analgesic. CONCLUSION Preoperative transarterial embolization using a gelatin sponge appears to be feasible and safe, and may contribute to decreasing IBL.

Abstract
Pressure sore pertains to tissue damage or necrosis that occurs due to lack of adequate nutrition following long-term exposure to pressure and decreased blood circulation. The aim of the study was to examine the effects of gelatin sponge combined with moist wound-healing nursing intervention in the treatment of phase III bedsore. In total, 50 patients with phase III bedsore were included in the present study. The patients were randomly divided into the control (n=25) and observation (n=25) groups. Patients in the control group received conventional nursing, while those in the observation group received gelatin sponge combined with moist wound healing nursing. The effects of the two nursing methods were compared and analyzed. The results showed that the improvement rate of the observation group was significantly higher than that of the control group (P<0.05). The Branden score and area of pressure sore of the observation group were significantly lower than those of the control group (P<0.05). The frequency and time of dressing change and the average cost of hospitalization of the observation group were significantly lower than those of the control group (P<0.001). In conclusion, gelatin sponge combined with moist wound-healing nursing intervention may significantly improve the treatment of phase III bedsore.

Abstract
An osteogenic inducer (OI) consisting of dexamethasone, vitamin C, and β-sodium glycerophosphate has the capacity to induce bone formation in vitro. The aim of this study was to assess the efficacy of the application of this OI on extraction socket healing. The bilateral first mandibular premolars were extracted from 75 New Zealand rabbits. Gelatin sponges carrying OI were implanted into the sockets. Sockets undergoing implantation of gelatin sponges alone were also evaluated, as well as non-implantation sockets. Specimens from each group were evaluated radiographically, histologically, and histomorphometrically using haematoxylin-eosin staining. Results showed earlier new bone formation and higher bone quality and quantity in the OI group compared to the other groups, and the differences were significant at 2, 4, 8, and 12 weeks postoperative. The OI significantly reduced the absorption of alveolar bone in terms of height; however, changes in the width were not significantly different between the three groups (P>0.05). The OI was shown to have a positive effect on healing of the tooth extraction sockets, was inexpensive, and was convenient to use during the operational procedure; therefore this could represent a promising implant material for human clinical application.

Abstract
OBJECTIVE This study aims to explore the preventive effect of dexamethasone gelatin sponge on the lumbosacral epidural adhesion in the laminectomy. METHODS A total of 36 Wista rats were divided into A, B, C and D groups randomly. Dexamethasone was not used in group A, Dexamethasone was used in group B, Dexamethasone was not used in group C but covered with gelatin sponge, dexamethasone gelatin sponge was used in group D. 3 rats in each group were sacrificed at 4, 8 and 12 weeks after operation respectively and the wound was opened to observe the dural scar formation and the dura adhesion. Immunohistochemical technique was used for histology observation. The expressions of VEGF and VEGFR2 in the epidural scar and surrounding tissues were detected with western blotting and immunohistochemical methods. RESULTS According to the Rydell score standard, there were different degree of adhesion formation in A, B and C groups while there was no obvious adhesion formation in D group. It was confirmed that the expressions of VEGF and VEGFR2 in group D were lower than that of the other groups. CONCLUSIONS Dexamethasone gelatin sponge could significantly reduce the occurrence of epidural scar tissue hyperplasia and adhesion after laminectomy in rats, and its mechanism may be related to the decreased expression of VEGF and VEGFR2.

Abstract
Purpose: The aim of this study was to report a comparison between the zinc oxide eugenol dressing and plasma rich in growth factor (PRGF) with gelatin sponge in the treatment of dry socket. Materials and Methods: This study comprised of 45 patients of dry socket in the span of one year. The patients were randomly divided into three groups on the basis of treatments: Group A (PRGF with gelatin sponge), group B (zinc oxide eugenol group), and group C (irrigation with sterile saline only). The clinical progress was noted at 1st, 2nd, 3rd, 7th, and 15th day after the treatment. Results: Patient's healing was better in group A than in group B but symptomatic pain relief was faster in group B. Group C fared worst in both aspects. Conclusion: We conclude that PRGF with gelatin sponge might be a treatment of choice in the management of dry socket.

Abstract
We and others have demonstrated that a mutation in Tsc2 is the rate-limiting step for renal carcinogenesis in the Eker rat model. Although inactivation of Tsc2 results in development of renal tumors, it is not sufficient for metastatic renal cell carcinomas (RCs) in the Eker rat. To investigate the additional genetic event(s) necessary for cancer metastasis, we have established highly metastatic S-Lk9d-SLM cell lines from a non-metastatic RC cell line (Lk9dL) by co-implantation with a foreign body (gelatin sponge). Since these cell lines were remarkably different in metastatic performance (all and none, respectively) despite having the same genetic background, they should be useful experimental tools to investigate metastasis-promoting events in renal carcinogenesis.

Abstract
AIM: To study the therapeutic effects of transcatheter arterial three-segment chemoembolization for hepatocellular carcinoma (HCC).
METHODS: According to the anatomy of vessels, the tumor capillary networks, muscular arterioles and feeding arteries were successively occluded using lipiodol ultra-fluid (LUF), sinobufagin microsphere (SBMs) and particles of gelatin sponge (PGS). In this series of 80 cases, therapeutic effects were evaluated in 76 cases.
RESULTS: There were 22 cases (28.9%) with partial response and 41 (53.9%) with minor response in the 76 evaluated patients. The 6-month, 1-year, 2-year and 3-year survival rates were 97.4%, 86.8%, 46.1% and 27.6% respectively.
CONCLUSION: This regimen was a rational chemoembolization method for HCC patients.

Abstract
Colonies of cells were obtained from human fetal lung tissue and exposed to recently isolated respiratory viruses. There was a considerable variation in the number of rounded cells found in different colonies exposed to rhinovirus types 2 and 9 (RV2 and 9), human coronavirus 229E (HCV), adenovirus type 3 (Ad3) and respiratory syncytial virus (RSV). Smaller colonies had more rounded cells than larger colonies. Clones were established from 9 out of 11 colonies. They varied in their rate of growth and the pattern formed on a plastic surface. They varied also in their virus susceptibility particularly to "difficult" rhinoviruses such as RV9 and SF1340. One cell clone (HL1/77 Clone 8), was highly susceptible to all these viruses. All cultures were more sensitive to RSV when maintained in F12K medium than in MEM, whereas there was no difference for rhinoviruses. Influenza A and B and parainfluenza 3 viruses sometimes produced cytopathic effect, and always produced haemadsorption, but unlike the previous strains could not be passed serially and presumably produced little infectious virus. All clones were rather insusceptible to Ad3; but the virus could be passed, whereas coxsackie virus B3 produced no CPE. Substantial yields of coronavirus and rhinovirus were obtained in gelatin sponge cultures. Two "very difficult" respiratory viruses which had just been adapted to tissue culture; namely, HS rhinovirus and JK coronavirus grew in 7 of 9 and in 6 of 9 clones respectively.
