Objective To establish a method based on 3D printing radiology equivalent phantom for individual radiotherapy dose verification,and to offer an assurance for the safety of 3D conformal radiotherapy.Methods Two patients' CT data was collected,reconstructing the first patient's skull and brain tissue to generate a skull-brain phantom for the purpose of testing the equivalent material.The second patient's data was used for whole head tissue reconstruction to produce a head phantom with equivalent material.By inserting ionization chamber dosimeters to target region for radiotherapy program,equivalent phantom dose distribution of lesions location was obtained in order to verify and calibrate the actual radiation treatment planning for patients.Results DR,CT images of the phantoms revealed that the difference of X-ray gray value between brain skull phantom and patient's skull was 13 721,CT value difference between equivalent tissue of brain skull phantom and that part of the patient was 35-40 HU,and CT difference between head phantom temporalis and that of the patient tissue was 18-28 HU.The imaging data indicated that the radiation equivalence of 3D printing phantom was similar to that of human body tissue,and the equivalent dose distribution accorded well with the normal range of treatment.The dose verification of phantom model can effectively improve the accuracy of the radiotherapy system.Conclusions The personalized radiotherapy phantom which based on the 3D printing and tissue equivalent technology is suitable for personalized radiation therapy validation.With advantages of easy accessibility,highly-personalized degree and high precision,this technology provides a reliable and safe way for radiation therapy.

Objective:To investigate the counteractive effect of mouse dermal fibroblasts (MdFBs) during their adipogenic differentiation against Staphylococcus aureus infection, and to explore its mechanisms. Methods:MdFBs were obtained from newborn C57BL/6 mice, and their adipogenic differentiation was induced by culture in an adipogenic medium for 48 hours. Real-time fluorescence-based quantitative PCR (RT-PCR) was performed to determine the mRNA expression of cathelicidin antimicrobial peptide (CAMP) on days 0-6 during the adipogenic differentiation of MdFBs, and Western blot analysis to determine the protein expression of CAMP in the culture supernatant of MdFBs during their adipogenic differentiation. MdFBs were divided into 4 groups: co-stimulation group stimulated by S. aureus suspensions and cultured in an adipogenic medium, adipogenic control group cultured in an adipogenic medium, S. aureus-stimulation group stimulated by S. aureus suspensions and cultured in a common medium, and control group stimulated by phosphate-buffered saline and cultured in a common medium; Western blot analysis and RT-PCR were conducted to determine the protein and mRNA expression of CAMP. S. aureus (5 × 10 4 CFU/ml) was cultured with the culture supernatant of MdFBs after 5-day adipogenic differentiation (adipogenic group), and the growth activity was evaluated every 2 hours during 10 - 24 hours after the start of co-culture; S. aureus cultured with the culture supernatant of MdFBs in a common medium served as the normal control group, and that cultured with cell-free culture supernatant served as the negative control group. Differences between groups were assessed using unpaired t-test or analysis of variance. Results:Significant differences were observed in the relative mRNA expression of CAMP among different time points (days 0, 1, 2, 4, and 6) during the adipogenic differentiation of MdFBs (1.14 ± 0.74, 68.04 ± 12.72, 683.12 ± 38.06, 1 390.68 ± 226.21, 454.57 ± 204.12, F = 50.08, P < 0.001) ; the CAMP mRNA expression was significantly higher on days 1, 2, 4, and 6 than on day 0 ( t = 9.09, 31.03, 10.63, 3.85, respectively, all P < 0.05), and showed an initial rise and subsequent fall during days 0 - 6. The CAMP protein expression in the culture supernatant of MdFBs peaked on days 2-5 and subsequently decreased. Significant differences were observed in the mRNA and protein expression of CAMP among the control group, S. aureus-stimulation group, adipogenic control group and co-stimulation group (mRNA: 0.08 ± 0.02, 0.38 ± 0.10, 0.49 ± 0.11, 0.80 ± 0.03, respectively, F = 43.25, P < 0.05; protein: 0.433 ± 0.176, 0.574 ± 0.176, 1.007 ± 0.176, 1.217 ± 0.176, respectively, F = 46.79, P < 0.05), and the relative mRNA and protein expression of CAMP was significantly higher in the co-stimulation group than in the adipogenic control group, S. aureus-stimulation group and control group (all P < 0.05). At 10 hours during culture, the growth activity of S. aureus was significantly lower in the adipogenic group (0.053 ± 0.015) than in the normal control group and negative control group (0.109 ± 0.015, 0.106 ± 0.015, t = 11.30, 13.26, respectively, both P < 0.05) ; during 10 - 24 hours, the growth activity of S. aureus also showed a significant decrease in the adipogenic group compared with the normal control group and negative control group (all P < 0.05) . Conclusion:MdFBs secreted CAMP during the adipogenic differentiation, and could inhibit the proliferation of S. aureus.

Objective To investigate the clinical effectiveness of foam sclerotherapy for lower extremity varicose vein with deep venous valve incompetence.Methods A retrospective study was carried out in 124 patients (185 limbs) receiving foam sclerotherapy in our department.Sixty-one limbs diagnosed as deep venous valve incompetence were categorized as the observation group,while 124 limbs without that were the control group.The main outcome were success rate,remission rate of various symptoms and signs,the scores of CEAP and CIVIQ.Results The follow up rate was 69.3％,and the follow-up period ranged from one to nine months.There was no statistical difference in the success rate between the observation group (93.4％) and control group (94.4％)(P＞0.05).However,the symptom of heaviness and oedema and the CIVIQ scores in observation group be inferior to the control group,and the difference of them were statistically significant (P＜0.05).Conclusion Deep venous valve incompetence could not decrease the success rate of foam sclerotherapy,but may influence the remission of some symptoms.It should be supplemented with medical elastic stockings or ringing of femoral veins.

Objective To investigate the effect of endoscopic prebiopsy forceps on the detection rate of polyps in the right semicolon.Method Clinical data of 148 patients diagnosed and treated from March 2022 to December 2022 who were detected as polyps in the right semicolon by general electronic colonoscopy were collected,and clinical data of the patients who underwent endoscopic prebiopsy forceps were re-examined and the patients underwent endoscopic treatment within 1 month.The differences in general data,polyp number detected,polyp size,morphology and pathological diagnosis between the two groups were analyzed and compared.Results 168 polyps were detected in the right semicolon in the general colonoscopy group,and 41 polyps were missed in reexamination using endoscopic prebiopsy forceps,with a missed diagnosis rate of 19.62%.The detection rate of<5 mm polyps was higher in the endoscopic prebiopsy forceps group than that of general colonoscopy group,the difference was statistically significant(P<0.05).The polyps in the two groups were mainly wide-basal type,and the pathological properties were mainly tubular adenoma,there was no statistical significance among all groups(P>0.05).No complications such as bleeding and perforation occurred in the two groups.Conclusion Endoscopic prebiopsy forceps can significantly improve the detection rate of polyps in the right semicolon,in particular,the intraoperative search for disappeared preoperatively identified intestinal polyps,as well as smaller diameter intestinal polyps,which is worthy of further clinical promotion.

Objective:To investigate the clinical efficacy of middle-preserving pancreatectomy (MPP).Methods:The retrospective and descriptive study was conducted. The clinicopathological data of two patients who underwent MPP in Fujian Provincial Hospital from July 2019 to October 2019 were collected. Case 1 was a 52-year-old woman with multiple serous cystic neoplasms of the pancreatic head and tail. Case 2 was a 20-year-old man with chronic pancreatitis and multiple pancreatic duct stones. After comprehensive evaluation, two patients were performed laparoscopic pancreatic head tumor resection+ pancreatic tail resection+ splenectomy+ pancreaticojejunostomy and duodenum-preserving pancreatic head resection+ pancreatic tail resection+ lithotomy by longitudinal pancreatic duct incision+ side-to-side pancreaticojejunostomy, respectively. Observation indicators: surgery, operation time, volume of intraoperative blood loss, blood transfusion, postoperative fasting blood glucose, postoperative complications, duration of postoperative hospital stay, postoperative pathological examination, and follow-up. Follow-up was performed using outpatient examination and telephone interview to detect new-onset diabetes mellitus, pancreatic enzyme replacement therapy and disease recurrence up to March 2020.Results:Two patients successfully underwent MPP. The operation time of case 1 and case 2 were 470 minutes and 400 minutes, the volume of intraoperative blood loss were 200 mL and 100 mL, respectively. No blood transfusion was performed in either patient. The postoperative fasting blood glucose fluctuated between 5.4 and 11.8 mmol/L in case 1, and fluctuated between 5.9 and 11.3 mmol/L in case 2. Case 1 developed abdominal infection after operation, and was discharged after anti-infective treatment. Case 2 had good recovery with no complication. No pancreatic fistula or perioperative death occurred in two patients. The duration of postoperative hospital stay were 12 days and 8 days of case 1 and case 2, respectively. The pathological examination of case 1 showed serous cystadenoma of the pancreatic head and pancreatic tail. The pathological examination of case 2 showed that slightly dilated pancreatic ducts of the pancreatic head and tail with multiple stones and chronic inflammatory cells infiltration around the pancreatic ducts. The length of pancreas preserved was 8.5 cm and 8.3 cm of case 1 and case 2 on postoperative computed tomography (CT) reexamination. Two patients were followed up for 5 months and 7 months, respectively. During the follow-up, both patients had no new-onset diabetes and they didn′t require pancreatic enzyme replacement therapy. Both patients underwent upper abdominal CT examination at postoperative 5 months, which showed good blood supply in middle pancreas and no signs of recurrence of cystadenoma or stones.Conclusions:MPP is a safe and feasible procedure for the treatment of multifocal pancreatic lesions. The procedure can eradicate the lesions and ensure good control of blood glucose in patients.
