Objective To investigate and analyze the occupational stress levels and influencing factors among radiation workers in China, and provide a reference for alleviating occupational stress and promoting mental health. Methods Using the general situation questionnaire, Effort-Reward Imbalance questionnaire, and radiation protection knowledge questionnaire, a convenience sampling method was adopted to investigate the occupational stress of 243 radiation workers in Liaoning, Fujian, Guangdong, and Xinjiang provinces. The independent samples t-test, one-way analysis of variance, chi-square test, and binary logistic regression were used to analyze the influencing factors. Results The average score of Effort-Reward Imbalance was 0.97 ± 0.22, and 100 (41.15%) radiation workers had occupational stress. There were significant differences in the detection rate of occupational stress among radiation workers of different ages, working years in radiation positions, monthly incomes, daily sleep durations, and daily working hours (P < 0.05). Logistic regression analysis identified daily working hours as a factor contributing to occupational stress. Conclusion The occupational stress among radiation workers in China is relatively severe. It is recommended to pay attention to the associated risks and implement targeted intervention measures to reduce the impact of occupational stress.

Objective:To explore the risk factors for atrial fibrillation in adult patients with critically severe burns after the first surgery.Methods:This study was a retrospective case series study. From January 1, 2018 to March 31, 2023, 211 adult patients with critically severe burns were admitted to the Department of Burns of Tongren Hospital of Wuhan University & Wuhan Third Hospital and met the inclusion criteria, including 158 males and 53 females, aged 24-81 years. According to whether atrial fibrillation occurred after the first surgery, the patients were divided into postoperative atrial fibrillation (POAF) group (23 cases) and non-POAF group (188 cases). The following indexes of patients in POAF group were collected, including the onset time, duration, treatment method, and number of patients with more than once of atrial fibrillation after the first surgery. The following data of the two groups of patients were collected, including general data, such as gender, age, burn type, total burn area, full-thickness burn area, inhalation injury, underlying diseases, mechanical ventilation, and sepsis; electrolyte imbalance and blood index level before the first surgery; the first surgery-related information such as surgical length and surgical method; volume changes and vital signs during the first surgery, such as total volume of fluid infusion, total volume of blood transfusion, volume of blood loss, hypotension, and hypothermia; postoperative hypothermia; inflammatory index levels before the first surgery and on the first day after the first surgery, such as procalcitonin levels, white blood cell count, neutrophil count, lymphocyte count, platelet count, neutrophil to lymphocyte ratio (NLR), platelet count to lymphocyte ratio (PLR); mortality within 30 days of admission. The independent risk factors for occurrence of atrial fibrillation in adult patients with critically severe burns after the first surgery were screened.Results:The onset time of atrial fibrillation of patients in POAF group was 2 (2, 4) hours after the first surgery, and the duration of atrial fibrillation was 16 (6, 26) hours. Twenty-one patients were treated with intravenous injection of amiodarone, two patients were treated with cardiac electrical cardioversion, and atrial fibrillation of all patients converted to sinus rhythm after treatment. Three patients experienced atrial fibrillation more than once. The age was 59 (42, 70) years and the total burn area was 90% (70%, 94%) total body surface area (TBSA) in patients in POAF group, which were significantly higher than 48 (38, 56) years and 70% (60%, 83%) TBSA in non-POAF group (with Z values of -2.64 and -3.56, respectively, P<0.05). Compared with those in non-POAF group, the incidence rate of inhalation injury of patients in POAF group was significantly higher ( χ2=4.45, P<0.05), the total volumes of fluid infusion and blood transfusion during the first surgery were significantly increased (with Z values of -3.98 and -3.75, respectively, P<0.05), the incidence rates of hypothermia during the first surgery and hypothermia after the first surgery were significantly increased (with χ2 values of 8.24 and 18.72, respectively, P<0.05), the levels of procalcitonin before the first surgery and on the first day after the first surgery, as well as the NLR on the first day after the first surgery were significantly increased (with Z values of -3.03, -2.19, and -2.18, respectively, P<0.05), the lymphocyte count (with Z values of -2.07 and -2.60, respectively, P<0.05) and platelet count (with Z values of -3.35 and -3.58, respectively, P<0.05) were significantly reduced before the first surgery and on the first day after the first surgery, and the mortality rate within 30 days of admission was significantly higher ( χ2=4.03, P<0.05). There were no statistically significant differences in other indexes between the two groups of patients ( P>0.05). Multivariate logistic regression analysis showed that age, total burn area, and intraoperative hypothermia were independent risk factors for the occurrence of atrial fibrillation in adult patients with critically severe burns after the first surgery (with odds ratios of 1.08, 1.07, and 4.18, 95% confidence intervals of 1.03-1.12, 1.03-1.11, and 1.48-11.80, respectively, P<0.05). Conclusions:Age, total burn area, and intraoperative hypothermia are independent risk factors for the occurrence of atrial fibrillation in adult patients with critically severe burns after the first surgery. Patients with atrial fibrillation have an increased risk of death.

Objective:To analyze the efficacy and feasibility of performing a new surgical procedure, tunnel esophagogastrostomy, to perform proximal gastrectomy.Methods:The study cohort comprised 10 consecutive patients who had undergone esophagogastrostomy by the tunnel technique in Jiangsu Cancer Hospital between October 2019 and July 2022. All patients were male. Their average age was (64.2±8.1) years and body mass index (25.5±3.2) kg/m2. Nine had upper gastric body adenocarcinoma, the remaining one having signet ring cell carcinoma. TNM staging of the tumors showed that seven were Stage IA, one Stage IB, one Stage IIA, and one Stage IIIA. Briefly, tunnel esophagogastrostomy is performed as follows: After performing a proximal gastrectomy, a rectangular seromuscular flap (3.0 cm × 3.5 cm) is created. The posterior esophageal wall is sutured to the gastric wall at the orad end of the seromuscular flap 5 cm from the stump with three to four stitches. Next, the stump of the esophagus is opened, the posterior esophageal wall is sutured to the gastric mucosa and submucosa, and the anterior esophageal wall is sutured to the full layer of the stomach. Finally, the caudad end of the seromuscular flap is closed. Data on surgical safety, postoperative morbidity, and postoperative reflux esophagitis were analyzed. All enrolled patients completed endoscopic follow-up 1 year and 2 years after surgery.Results:All procedures were completed. They comprised four cases of laparoscopic assisted surgery, four of DaVinci robotic surgery, and two of open surgery. The mean operation time was 212.7±33.2 mins, mean anastomosis time (51.6±5.3) minutes, mean tunnel preparation time (20.0±3.5) minutes, and mean operative blood loss (90.0±51.6) mL. The time to first postoperative passage of flatus was (64.8±11.5) hours. The mean hospital stay after surgery was (9.2±1.7) days. There were no postoperative complications above Clavien-Dindo Grade II. The mean preoperative Reflux Disease Questionnaire score was (3.3± 0.4) before the surgery, (3.8±1.0) 1 month postoperatively, and (3.3±0.4) 12 months postoperatively. All patients underwent endoscopic follow-up; no anastomotic stenoses were found. However, one patient had Grade A reflux esophagitis 1 year after surgery and another Grade B reflux esophagitis 2 years after surgery.Conclusion:Esophagogastrostomy by the tunnel technique is a safe and feasible means of performing proximal gastrectomy.

Objective:To investigate the clinical efficacy and mechanism of Ganoderma lucidum hypoglycemic formula in the treatment of insulin resistance in patients with type 2 diabetes mellitus (T2DM) with liver and kidney yin deficiency. Methods:A total of 86 patients with T2DM with liver and kidney yin deficiency who were diagnosed and treated at Yueyang Hospital of Integrated Traditional Chinese and Western Medicine, Shanghai University of Traditional Chinese Medicine from January 2021 to February 2022 were included in this study. These patients were divided into a control group and a treatment group, with 43 patients in each group using a 1:1 ratio using the sealed envelope method. Both groups were treated with standardized Western medicine. The treatment group was also treated with the Ganoderma lucidum hypoglycemic formula. All patients were followed up for 12 weeks. The clinical symptoms, curative effect, glucose and lipid metabolism, inflammatory factors, oxidative stress change, and safety were compared between the two groups. Results:The total response rate in the treatment group was 88.4% (38/43), which was significantly higher than 53.5% (23/43) in the control group ( χ2 = 12.69, P < 0.001). After treatment, the traditional Chinese medicine syndrome score, fasting blood glucose, 2-hour postprandial blood glucose, glycosylated hemoglobin, insulin resistance index, total cholesterol, triglyceride, tumor necrosis factor α, and interleukin-6 decreased in each group. The amplitudes of decrease of the above indexes were greater in the treatment group compared with the control group (all P < 0.05). C-peptide in the fasting state, C-peptide at 2 hours after a diet, and superoxide dismutase increased in each group. The amplitudes of increase of the three indexes were greater in the treatment group compared with the control group (all P < 0.05). Conclusion:Ganoderma lucidum hypoglycemic formula can greatly improve insulin resistance and glucose and lipid metabolism in T2DM patients with liver and kidney yin deficiency. The underlying mechanism may be to further reduce the inflammatory response and anti-oxidative stress by down-regulating tumor necrosis factor α and interleukin-6 levels and up-regulating superoxide dismutase level, thereby effectively alleviating insulin resistance in T2DM.

Periarticular fracture of the shoulder is a common type of fractures in the elderly. Postoperative adverse events such as internal fixation failure, humeral head ischemic necrosis and upper limb dysfunction occur frequently, which seriously endangers the exercise and health of the elderly. Compared with the fracture with normal bone mass, the osteoporotic periarticular fracture of the shoulder is complicated with slow healing and poor rehabilitation, so the clinical management becomes more difficult. At present, there is no targeted guideline or consensus for this type of fracture in China. In such context, experts from Youth Osteoporosis Group of Chinese Orthopedic Association, Orthopedic Expert Committee of Geriatrics Branch of Chinese Association of Gerontology and Geriatrics, Osteoporosis Group of Youth Committee of Chinese Association of Orthopedic Surgeons and Osteoporosis Committee of Shanghai Association of Chinese Integrative Medicine developed the Chinese expert consensus on the diagnosis and treatment of osteoporotic periarticular fracture of the shoulder in the elderly ( version 2023). Nine recommendations were put forward from the aspects of diagnosis, treatment strategies and rehabilitation of osteoporotic periarticular fracture of the shoulder, hoping to promote the standardized, systematic and personalized diagnosis and treatment concept and improve functional outcomes and quality of life in elderly patients with osteoporotic periarticular fracture of the shoulder.

Objective:To investigate the effects of miniature free groin perforator flaps in repairing small wounds on hands.Methods:The retrospective observational study was conducted. Fifteen patients with 16 small wounds on hands were admitted to Tongren Hospital of Wuhan University & Wuhan Third Hospital from July 2020 to October 2022, including 12 males and 3 females, aged 19 to 56 years. The size of skin and soft tissue defect was 2.0 cm×1.5 cm to 6.0 cm×3.0 cm after debridement. According to size and shape of the wounds, 13 single-lobe perforator flaps and 2 bilobed perforator flaps were designed in the groin region, with the flap size of 4.5 cm×2.5 cm to 7.5 cm×3.5 cm. According to the condition of the recipient area, the arteries and veins at the pedicle of the flap were anastomosed to the arteries and veins of the recipient area respectively. The wounds in the donor area of the flap was closed by layered and tension-reducing suture. The thickness of the flap was measured during operation. The survival of the flap was observed, and the complications in the donor and recipient areas were recorded after operation. The appearance and texture of the flap were observed during follow-up. At the last follow-up, the sensory recovery of the affected hand was evaluated, the function of the affected hand was evaluated according to the trial standard of the upper limb partial function evaluation of the Hand Surgery Society of the Chinese Medical Association, the scar in the donor and recipient areas were observed, and the satisfaction of patients for the curative effects was inquired.Results:The thickness of the flap was ranged from 0.3 to 1.0 cm, with an average thickness of 0.6 cm. After operation, 11 single-lobe flaps and 2 bilobed flaps survived well; in the left 2 single-lobe flaps, one flap had venous crisis but returned to normal after removing stitches to reduce tension and bloodletting of flaps, while the other one flap had a little necrosis on tip but healed after dressing change. No complications occurred in donor and recipient areas. During follow-up of 8 to 35 months after operation, the flaps had good elasticity and soft texture; 8 flaps were slightly bloated and were trimmed 3 to 8 months after operation, while the appearances of the other flaps were good. At the last follow-up, all flaps recovered protective feeling; the function of the affected hand was evaluated as excellent in 10 cases, good in 4 cases, and fair in 1 case; only linear scar remained in the donor and recipient areas; the patients were satisfied with the appearance and function recovery of the affected hand.Conclusions:The miniature free groin perforator flaps in repairing small wounds on hands have the advantages of high survival rate of flaps, hidden flap donor area, little damage, few complications, good repair effect, etc., showing clinical application value. It is recommended for repairing non-functional wounds on hands.

Objective:To investigate the clinical effects of free transplantation of inguinal flap in repairing electrical burn wounds of mice in the limbs.Methods:A retrospective observational study was conducted. From January 2012 to May 2023, 24 male patients with electrical burns in the limbs meeting the inclusion criteria, aged 20 to 69 years, were admitted to the Department of Burns of Tongren Hospital of Wuhan University & Wuhan Third Hospital. Totally 27 limbs were involved, including 18 upper limbs and 9 lower limbs. After debridement, the wound area in the limbs proposed to be repaired with the inguinal flap was 5.0 cm×1.5 cm-20.0 cm×9.0 cm. A total of 26 operations were performed in 24 patients, and 27 free inguinal flaps with area being 5.0 cm×3.5 cm-22.0 cm×12.0 cm were resected, including 6 for lobed transplantation, 2 for chimeric transplantation with iliac bone graft, 3 for conjoined transplantation with pedicled latissimus dorsi myocutaneous flap, and 1 for conjoined transplantation with free paraumbilical perforator flap. Indocyanine green angiography was used to evaluate the blood supply of the inguinal flap during operation, to guide arterial supercharge during transplantation. Among the transplanted inguinal flaps, 5 were pedicled with the common trunk of the superficial circumflex iliac artery and the superficial abdominal wall artery, 13 were pedicled with the superficial circumflex iliac artery alone, 6 were pedicled with the superficial abdominal wall artery alone, and the remaining 3 were simultaneously anastomosed with the superficial circumflex iliac artery and the superficial abdominal wall artery for arterial supercharge. In another patient, the deep branch of the superficial circumflex iliac artery was used as a bridging vessel to recanalize the proper artery of the index finger in the distal segment. The wound in the donor area were sutured directly. The blood supply status of the inguinal flap immediately after resection but before cutting off blood vessels and after transplantation and vascular anastomosis was recorded. The survival of the tissue flap, the fixation of the iliac bone graft, and the healing of secondary defect in the donor area were observed after surgery. The appearance of the inguinal flap and the functional recovery of the recipient area were followed up. At the last follow-up, the function of the affected upper limb was scored using the Arm, Shoulder, and Hand Disability (DASH) scoring scale, and the satisfaction of patients with the efficacy of each surgical treatment was investigated by referring to the 5-level Likert scale.Results:Totally 27 inguinal flaps showed good arterial blood perfusion and venous return immediately after resection but before cutting off blood vessels and after transplantation and vascular anastomosis. Except for one inguinal flap that developed necrosis 12 days after operation and was repaired by split-thickness skin graft from the head, the remaining 26 inguinal flaps and conjointly transplanted tissue flaps survived completely without vascular crisis. The iliac bone graft was fixed securely after operation. All secondary defects in donor area healed well after operation. After 6 to 36 months of follow-up, the inguinal flap was soft in texture, without obvious swelling, the function of the recipient area was significantly improved as compared with that before surgery, and the protective feeling of the inguinal flap was restored. At the last follow-up, the functional scores of DASH scoring scale of the 18 affected upper limbs ranged from 0 to 100 (with a mean of 27). The patients were very satisfied with the efficacy of 17 surgical treatments and relatively satisfied with the efficacy of 9 surgical treatments.Conclusions:The donor area of the inguinal flap is concealed, and the damage resulted from flap resection in this area is small. This flap has a rich blood supply. In the electrical burn wounds of mice in the limbs repaired with lobed transplantation, chimeric transplantation, and conjoined transplantation with other flaps, the appearance and function of the recipient area are well restored, and the patients' satisfaction with the efficacy of surgical treatment is high, which is worthy of clinical promotion.
