Insulin and hypertonic glucose in the management of aseptic fat liquefaction of post-surgical incision: a meta-analysis and systematic review

Molecular mechanism of Flt-1 protein and the regulation of monocytes modulate endothelial cell in wound healing sites via PGF/FLT1 signaling

The purpose of this study was to investigate the mechanism of action of the Flt-1 protein molecule during wound healing and to analyze how monocytes regulate endothelial cells at the wound healing site through the placental growth factor/Fms-like tyrosine kinase 1 (PGF/FLT1) signaling pathway. In this study, the PGF and Flt-1 knockdown mice models were constructed to observe the changes of wound healing. The expression of Flt-1 mRNA and protein during wound healing in human and mice biopsies was detected by qPCR and immunofluorescence. The interaction between monocytes and endothelial cells, especially the role of proteins and RNAs in the PGF/FLT1 signaling pathway in this process, was also analyzed. The results showed that the expression of Flt-1 protein was significantly up-regulated during wound healing, especially in endothelial cells, which promotes the proliferation and migration of endothelial cells, accelerates angiogenesis, and thus accelerates the rate of wound healing. In contrast, Flt-1 knockdown suppresses these processes. Monocytes can activate the FLT1 receptor on endothelial cells by secreting PGF, and then promote the proliferation and migration of endothelial cells.

Development of novel prognostic protein signatures in ovarian cancer: Molecular structure and immune function of AQP5 protein and CTDP1 protein

Ovarian cancer is a serious gynecological malignancy, and early identification of prognostic markers is critical to improve clinical outcomes. Aquaporin 5 (AQP5) and cell cycle regulatory protein CTDP1 are considered as potential prognostic protein markers, but their specific molecular structure and immune function have not been thoroughly studied. The aim of this study was to investigate the molecular structure of AQP5 and CTDP1 and their immune function in ovarian cancer, to evaluate their potential as prognostic markers, and to provide new ideas for the diagnosis and efficacy monitoring of ovarian cancer. Cox regression analysis and LASSO regression were used to construct the risk prognosis model, and the preliminary verification was carried out. Finally, cell culture and high-resolution gene expression analysis were used to investigate the expression of AQP5 and CTDP1 and their roles in the immune microenvironment. The results showed that AQP5 and CTDP1 were highly expressed in ovarian cancer cell lines and were closely related to tumor immune invasion. The immunomicroenvironment analysis based on GRN showed that they showed a positive correlation with tumor-related immune cells. Through the constructed risk model, AQP5 and CTDP1 significantly affect patient prognosis, suggesting their potential as prognostic markers.

Development and prospects of natural orifice specimen extraction surgery for colorectal cancer: a review article

The natural orifice specimen extraction surgery (NOSES) procedure is an innovative approach to treating colorectal cancer that offers several advantages. First, the NOSES technique is minimally invasive, reducing the incidence of postoperative complications such as wound infection and fat liquefaction. Second, it provides excellent pain relief and improves cosmetic outcomes by requiring fewer abdominal incisions, thereby increasing patient satisfaction. Additionally, NOSES provides all of the advantages of minimally invasive surgery and enables patients to recover quickly, helping patients return to their normal lives faster. This approach aligns with the concept of patient-centered care and significantly improves patient quality of life. The positive results noted at both short- and long-term postoperative follow-up indicate that NOSES is a valuable option in cancer care. Despite its many benefits, NOSES has also been challenged by bacteriology, oncology, and ethics. This paper presents a review of recent research progress regarding NOSES in the treatment of colorectal cancer. In this article, we examined the advantages and disadvantages of NOSES in clinical practice and discussed potential issues and solutions.

Fat Liquefaction and Lipo Particles in a CIED Pocket During Generator Change-Not an Infection: A Rare Case Report

A case of fat liquefaction and fat particles in the pacemaker pocket observed in a female patient 12 years after implantation. The patient had no symptoms and no signs of infection or other discomfort of the heart and pacemaker pocket. The biochemical analysis showed a slight increase in cardiac troponin T, 0.026 ng/mL (reference range, <0.016 ng/mL), a high increase in total cholesterol, 8.70 mmol/L (reference range, <5.18 mmol/L), and low density lipoprotein, 5.38 mmol/L (reference range, <3.37 mmol/L). Thick yellow liquid was seen to flow out of the pacemaker pocket when the pocket was opened, and many fat particles were found adhering to the wall of the pacemaker pocket during the pacemaker replacement procedure. Fat and fibrillar connective tissue with a few inflammatory cells, local tissue degeneration and necrosis were shown on immunohistochemical staining and no bacterial growth including anaerobic bacteria was observed. The aseptic necrosis of post-implantation complications is helpful for differential diagnosis in CIED complication. Moreover, the identification of fat liquefaction has important clinical significance for patient management and surgical decision-making.

Comparison between laparoscopic versus open appendectomy in morbid obese patients

Purpose

To evaluate the laparoscopic approach advantages for the management of acute appendicitis in morbidly obese patients.

Methods

A prospective study included all morbidly obese patients who had presented to the emergency department at Sohag University Hospitals and were diagnosed with acute appendicitis between the 1st of June 2022 and the 31st of January 2023. All those patients were invited to participate in the research by randomization. The authors informed patients and their first-degree relatives about both techniques, signed a consent form for participation in the study. The authors categorized them into two groups; laparoscopic approach (group I) and open approach (group II). Comparisons were based on operative time, intraoperative complications, length of hospital stay, postoperative complications, and time until return to normal daily activities.

Results

The study enrolled 64 patients: 33 had a laparoscopic appendectomy, and 31 had an open appendectomy. The groups were similar in terms of clinicopathologic characteristics. The operating time was significantly shorter for Group I patients than Group II (Group I, 49.09±16.21 min vs. Group II, 68.03±15.78 min; P value less than 0.05). Regarding the length of hospital stay, twenty-six patients (78.8%) were discharged within the 1st 24 h in the laparoscopic group versus 17 patients (54.8%) in the open group (P value 0.041). The time until return to the routine daily work was significantly shorter in the laparoscopic group (11.27±2.6 days) than in the open group (17.23±4.8 days) (P value less 0.05). Four postoperative complications were reported in the study population: wound complications (infection, seroma formation), residual abdominal abscess, paralytic ileus, and thromboembolic complications (Deep venous thrombosis and pulmonary embolism). Group II had a statistically significant higher complication rate (32.3%) than Group I (9.09%) (P value 0.007).

Conclusion

Laparoscopic appendectomy had superior clinical outcomes than an open appendectomy in morbidly obese patients. In addition to minimal invasiveness and better cosmetic results, it has a great advantage as a diagnostic and therapeutic tool in morbidly obese patients with suspected appendicitis. It is also a safe and feasible approach with a low rate of complications with a well-trained expert surgeon.

Clinical Characteristics and Treatment of Adult Idiopathic Carpal Tunnel Syndrome Accompanied with Trigger Digit

Purpose

To investigate the clinical characteristics and treatment of adult idiopathic carpal tunnel syndrome (CTS) accompanied with trigger digit.

Materials and Methods

A retrospective analysis was performed on a total of 74 patients with adult idiopathic CTS accompanied with trigger digit admitted to and treated at the Hand Surgery Department of Ningbo No. 6 Hospital from January 1, 2017 to December 31, 2019. Data on patients' gender, age, occupation, course of the disease, menstruation, surgeries, examination-related information, complications, treatment methods, and prognoses during follow-up were recorded and subsequently used to analyze the pathogeneses, clinical characteristics, and treatment.

Results

A total of 74 patients (72 females and 2 males) were included. Among female patients, 51 were postmenopausal and 18 were non-postmenopausal. There were 101 fingers with trigger digit, including 14 patients with trigger digit in both hands, and 115 wrists affected by the CTS. The average course of CTS was 34.5 ± 49.3 months, and that of trigger digit was 10.5 ± 22.4 months. Seventy had both trigger digit and CTS in one hand, while among patients with both hands involved, only 4 had trigger digit or CTS in one hand. Eighty-nine fingers underwent A1 pulley release, and 104 hands underwent carpal tunnel surgery, with steroids being injected under the adventitia of the median nerve during the surgery. All patients who underwent surgeries had I/A-healed incisions, and 14 of them had obvious synovial hyperplasia observed in the carpal tunnel and flexor tendon sheath during surgeries. Follow-up visits, which lasted 3 to 35 months, had an average duration of 1.34 years and included 72 patients. In 63 patients (63/72), the syndrome of tenosynovitis and numbness disappeared and normal hand functions were restored; in 6 patients, the numbness in hands greatly improved and normal hand functions were almost completely restored, while no improvement in numbness of hands and limited hand functions were still observed in 3 patients.

Conclusion

CTS accompanied with trigger digit was more common in postmenopausal females, and the course of CTS was longer than that of trigger digit. CTS and trigger digit were more likely to simultaneously occur in the same hand, while some patients might not have obvious synovial hyperplasia in the carpal tunnel. Surgeries were effective in severe cases.

Comparison of Iliac Bone Transplantation with Bone Transport in the Treatment of Femur Fracture and Bone Defect

Objective

To compare the curative effect of iliac bone transplantation with the bone transport in the treatment of femur fracture complicated with a bone defect.

Methods

Patients with femur fractures and defects who were admitted to our hospital from January 1, 2020, to January 31, 2022, and met the inclusion criteria were retrospectively selected and allocated into an iliac bone transplantation group or a bone transport group. The treatment effect and quality of life of the two groups were compared.

Results

A total of 98 patients who met the inclusion standards were enrolled, including 50 cases in the iliac bone transplantation group and 48 cases in the bone transport group. There were no significant differences in IL-6, IL-8, TNF-α, visual analog scale (VAS) score, or Japanese Orthopedic Association (JOA) score between the two groups on postsurgical day 1 (p=0.051, 0.150, 0.102, 0.564, and 0.826 respectively), but there were significant differences in the above index on postsurgical day 7 (all p < 0.01). There were no significant differences in social function, physical function, role function, and cognitive function between the two groups one week after the operation (p=0.245, 0.051, 0.102, and 0.067, respectively), but there were significant differences in the above parameters at one month after operation (p=0.001, 0.005, 0.005, and 0.001, respectively). The total effective rate of the bone transplantation group was significantly better than that of the iliac bone transplantation group (p=0.026). The number of postoperative complications in the bone removal group was significantly fewer than that of the iliac bone graft group (p=0.001).

Conclusion

Bone transport is effective in treating femur fractures complicated with bone defects, with fewer postoperative complications.

A Retrospective Study of Chemotherapy and 3D-Image-Guided Afterloading Intracavitary Radiotherapy in Locally Advanced Cervical Cancer

Aim

To investigate the value of neoadjuvant chemotherapy combined with 3D-image-guided afterloading intracavitary radiotherapy in locally advanced cervical cancer (LACC).

Methods

Patients with cervical cancer admitted to our hospital from January 1, 2020 to January 1, 2021 were retrieved and analyzed. Cases treated with neoadjuvant chemotherapy and 3D-image-guided afterloading intracavitary radiotherapy were assigned into the observation group (OG), while cases with neoadjuvant chemotherapy alone were assigned into the control group (CG). The short-term effects were determined by RECIST 1.1. Total effective rate (TR) = complete remission (CR) + partial remission (PR). The serum levels of squamous epithelial cell carcinoma antigen (SCC-Ag), glycoantigen 125 (CA125), carcinoembryonic antigen (CEA), and vascular endothelial growth factor (VEGF) were assessed. In view of the difference between tumor markers and diameters before and after treatment, the correlation between them was analyzed by Pearson test. The adverse events were compared, and the amount of operative bleeding and operation time were evaluated. Cox regression analysis was conducted to assess the influencing factors of 1-year disease-free survival time.

Results

Sixty-seven patients were retrieved, including 30 cases in the OG and 37 cases in the CG. There were no significant differences in age, pathological type, tumor size, FIGO stage, past medical history, or smoking history between the two groups (P > 0.05). The TR of patients in the OG was higher than that in the CG (P < 0.05). The SCC-Ag, CA125, CEA, and VEGF levels in the OG decreased markedly after treatment (P < 0.001). The difference in SCC-Ag, CA125, CEA, and VEGF was positively correlated with the difference in tumor diameter before and after treatment (P < 0.05). The incidence of adverse events revealed no obvious difference between the OG and CG (P > 0.05). Cox regression analysis showed that FIGO stage and treatment regimens were independent prognostic factors for 1-year disease-free survival (P < 0.05).

Conclusion

Neoadjuvant chemotherapy combined with 3D-image-guided afterloading intracavitary radiotherapy can improve the TR rate and 1-year disease-free survival of LACC patients without increasing the incidence of adverse events.

Camrelizumab and Apatinib Combined with Radiotherapy Is Effective in Advanced Oligometastatic Non-Small-Cell Lung Cancer

Objective. To investigate the effect of camrelizumab + apatinib combined with radiotherapy on the expression of TRIM27, SCC-Ag, and CYFRA21-1 in advanced oligometastatic non-small-cell lung cancer (NSCLC). Methods. A retrospective analysis of patients with oligometastatic NSCLC who were treated at our hospital from January 1, 2021, to March 31, 2022. Patients who met the inclusion criteria were summarized into an observation group (camrelizumab on the basis of the control group), or a control group (radiotherapy combined with oral apatinib). The disease control rate, immune function, changes in the levels of TRIM27, SCC-Ag, CYFRA21-1, and the occurrence of adverse effects were compared between the two groups. Result. There were 86 patients who met the inclusion criteria, with 53 cases in the observation group and 33 cases in the control group. There were significant differences in complete remission (CR, 25/53 vs. 10/33), partial remission (PR, 17/53 vs. 12/33), disease control (DC, 7/53 vs. 4/33), disease progression (DP, 4/53 vs. 7/33), and disease control rate (49/53 vs. 26/33) between the observation group and the control group. There was no significant difference in immune function between the two groups before treatment ( $p>0.05$ ). After treatment, the levels of CD3+, CD4+, CD4+/CD8+t cells, and NK cells in the observation group were higher ( $p=0.015$ , 0.035, 0.003, 0.001, respectively), while the level of CD8+t cells was lower ( $p<0.001$ ). There were no significant differences in TRIM27, SCC-Ag, or CYFRA21-1 between the two groups before treatment ( $p>0.05$ ). After treatment, the observation group had lower levels of TRIM27 ( $p=0.035$ ), SCC-Ag ( $p=0.045$ ), and CYFRA21-1 ( $p=0.003$ ). There was no significant difference in the occurrence of adverse events between the two groups ( $p<0.05$ ). Conclusion. Treatment of camrelizumab + apatinib combined with radiotherapy is effective for advanced oligometastatic NSCLC, with mild adverse effects.

Effects of Propofol Intravenous Anesthesia on Serum NGF, S100B Protein, and Immune Function in Patients with Bladder Cancer after Resection

Objective

To explore the efficacy of intravenous propofol anesthesia on patients with bladder cancer after resection, as well as its effect on cognitive and immune function.

Methods

Patients with bladder cancer and received resection of bladder cancer at our hospital from May 1, 2019, to November 30, 2021, were retrospectively retrieved and included in this study. The included patients were summarized into group A (isoflurane) and group B (intravenous propofol). The anesthesia intervention effect, serum NGF level, serum S100B protein level, and immune function before surgery, 6 h after surgery, 1 d after surgery, and 3 d after surgery were compared between the two groups.

Results

Eighty-six patients were retrieved. The anesthesia intervention effective rate of patients in group B was significantly higher than that of patients in group A (P < 0.01). The serum NGF and S100B of patients in both groups were significantly lower on postsurgical day 1, but in the trend to returning to those before intervention level on day 3. There were also fluctuations in immune function represented by changes in CD3+, CD4+, CD8+, and CD4+/CD8+ T cells, which showed return of function by postsurgical day 3.

Conclusion

The anesthetic effect of intravenous propofol in patients with bladder cancer resection is significantly more satisfactory than isoflurane, with a transient effect on serum NGF and S100B protein levels and patients' immune function, which suggests that intravenous propofol can be widely used for general anesthesia in clinical practice.

Effects of prophylactic antibiotics before peritoneal dialysis catheter implantation on the clinical outcomes of peritoneal dialysis patients

BACKGROUND

Peritoneal dialysis (PD) related infections, such as peritonitis, are still the main obstacle for the development of PD. Prophylactic antibiotic as one of the interventions to prevent early peritonitis was recommended to use before PD catheter insertion by International Society for Peritoneal Dialysis (ISPD) guidelines, In our hospital, however, since 2012, the prophylactic antibiotics for insertion of PD catheters were not allowed to use because of our hospital's regulation. In order to analyze the outcomes of PD patients without using prophylactic antibiotics before the PD catheter insertion, we compared the PD patients with or without prophylactic antibiotics before PD catheter insertion.

METHODS

This retrospective study included 247 patients undergoing permanent PD catheter placement with conventional open surgical method consecutively between February 2008 and June 2013. Of these, 154 patients were given intravenous cefazolin, 1.0 g, 0.5-2 h before the procedure (antibiotic group) and 93 patients were not given prophylactic antibiotics (nonantibiotic group). All the patients were administered intermittent PD within 24 h after PD catheter insertion. The early complications and long-term outcomes were recorded respectively.

RESULTS

There was no significant difference in the incidence of peritonitis and exit-site/tunnel infection and mechanical complications between the two groups in the first 30 days after the PD catheter implantation. In addition, after 6 years of follow-up, no difference was seen between the two groups in patient survival, technique survival, and peritonitis-free survival.

CONCLUSIONS

Our study does not show any beneficial effect of antibiotic prophylaxis in reducing the postoperative peritonitis.

Links between the Prophet Muhammad (PBUH) recommended foods and disease management: A review in the light of modern superfoods

Nutrition and other bioactive natural products present in specific foods within a balanced diet play an indispensable role in maintaining and promoting human health. Plants are rich sources of a balanced nutrition because of high content of bioactive products; hence, most of them recently have acquired the status of superfoods. It has been used since ancient times for the treatment of various ailments, and these traditional medicines still remain as one of the most affordable and easily accessible sources of treatment in the primary health-care system. The scientifically based use of these superfoods date back to the era of Prophet Muhammad along with other historical uses of plant products. Prescription of a large number of herbal foods such as dates, pomegranate, olives, figs, grapes, and black seeds was successfully proposed by him. These recently have become superfoods with their powerful healing properties and act as favorable dietary interventions for disease prevention as well as for the good maintenance of health. The use of these foods as ingredients of natural origin with fewer side effects seems to be more favorable than the chemical treatment, which is often complicated. The present review is an attempt to provide a brief survey of the literature on scientifically based significance of these superfoods carried out by various researchers and exploration of a wide spectrum of their pharmacological actions which include antidiabetic, anticancer, immune modulator, analgesic, anti-inflammatory, and hepatoprotective properties.
