Objective:To evaluate the clinical efficacy of Rougan Jianpi therapy combined with Mesalazine enema in the treatment of distal ulcerative colitis (DUC) with Ganyu-Pixu syndrome.Methods:This study is a prospective parallel randomized controlled study. From November 2021 to May 2022, 115 patients with DUC in Changshu Hospital Affiliated to Nanjing University of Chinese Medicine were selected and randomly divided into a control group of 58 patients and a study group of 57 patients. The control group was treated with Mesalazine enema, and the study group was treated with Rougan Jianpi Decoction on the basis of the control group. Both groups were treated for 8 weeks. The severity of the disease was evaluated by using the Modified Mayo Scale, and the clinical and endoscopic efficacy was evaluated based on the changes in the score before and after treatment. TCM syndromes were scored from four aspects: abdominal pain, diarrhea, mucopurulent bloody stool, Rectal tenesmus, and anal burning. The quality of life was evaluated by using the IBD Quality of Life Scale (IBDQ). The serum TNF-αand IL-10 level were detected by using ELISA method. The adverse reactions during treatment were observed and recorded.Results:The total effective rate of the study group was 91.23% (52/57), while that of the control group was 79.31% (46/58). The difference between the two groups was no statistically significant ( Z=1.47, P=0.143). The proportion of patients in the study group who achieved clinical response[40.35% (23/57) vs. 51.72% (30/58)] and clinical relief [59.65% (34/57) vs. 43.11% (25/58)] the total proportion were significantly higher than those in the control group [100.00% (57/57) vs. 94.83% (55/58); Z=1.97, P=0.049]. The proportion of patients with endoscopic response [52.63% (30/57) vs. 56.90% (33/58)] and mucosal healing [33.33% (19/57) vs. 17.24% (10/58)] the total proportion in the study group were significantly higher than those in the control group [85.96% (49/57) vs. 74.14% (43/58); Z=2.23, P=0.026]. after treatment, the IBDQ score [(194.3±15.1) vs. (172.6±18.4), t=6.90] in the study group was significantly higher than that of the control group. After treatment, the patient's TCM symptom score: mucopurulent bloody stool [(1.7±0.8) vs. (2.0±0.6), t=2.03], rectal tenesmus [(1.5±0.6) vs. (1.8±0.6), t=2.32] and anal burning [(1.3±0.6) vs. (1.6±0.7), t=2.38] in the control group were significantly lower than those in the control group ( P<0.05). The level of IL-10 [(53.3±8.0) ng/L vs. (49.0±6.7) ng/L, t=3.10] in the study group after treatment was higher than that of the control group ( P<0.01), and TNF-α [(28.3±7.9)ng/L vs. (36.8±8.1)ng/L, t=3.58] was lower than that of the control group ( P<0.01). There were no significant adverse reactions observed during the treatment in both groups. Conclusion:Method of Rougan Jianpi combined with mesalazine enema can improve the clinical symptoms of DUC patients, improve clinical efficacy, and have good safety.

Effects of thoracic segment epidural anesthesia on inflammatory factors in patients undergoing lung cancer surgery / 中国基层医药

Objective:To investigate the effects of thoracic segment epidural anesthesia on inflammatory factors in patients undergoing lung cancer surgery.Methods:The clinical data of 136 patients who underwent lung cancer surgery in the Second People's Hospital of Liaocheng from June 2020 to May 2022 were retrospectively analyzed. According to anesthesia methods, these patients were divided into an observation group ( n = 89) and a control group ( n = 47). The observation group was given thoracic segment epidural anesthesia, while the control group was given remifentanil infusion anesthesia. The tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and interleukin-10 (IL-10) levels in the epithelial lining fluid collected from the non-dependent lung, the plasma levels of TNF-α, IL-6, and malondialdehyde, arterial partial pressure of oxygen/inhaled oxygen fraction, the incidence of complications, the incidence of re-operations, numeric rating scale score, and the length of hospital stay were compared between the two groups. The effects of different anesthesia methods on lung cancer surgery were evaluated. Results:In each group, TNF-α, IL-6, and IL-10 levels in the epithelial lining fluid were significantly increased 30 minutes after termination of one-lung ventilation (T2) compared with those measured before one-lung ventilation (T1) ( t = 7.71, 77.10, 7.59, 3.41, 57.51, 5.74, all P < 0.05). In the observation group, TNF- α [(1.59 ± 0.53) ng/L, (1.89 ± 0.64) ng/L] measured at T1 and T2, IL-6 [(2.96 ± 0.82) ng/L] and IL-10 [(1.99 ± 0.53) ng/L] measured at T1 were significantly higher compared with those measured at the corresponding time points in the control group ( t = 10.45, 2.59, 2.00, 7.19, all P < 0.05). In the observation group, IL-6 measured at T2 [(38.91 ± 5.84) ng/L] was significantly lower than that in the control group ( t = 33.25, P < 0.001), and IL-10 measured at T2 [(2.51 ± 0.67) ng/L] was slightly, but not significantly higher than that in the control group ( P > 0.05). There was no significant difference in the plasma level of TNF- α measured at T1 and T2 between the two groups (both P > 0.05). Plasma levels of IL-6 in the two groups [(42.98 ± 5.29) ng/L, (27.93 ± 4.17) ng/L] measured at T2 were significantly increased compared with those measured at T1 ( t = 54.14, 61.06, both P < 0.001). In the observation group, TNF-α measured at T2 [(1.60 ± 0.56) ng/L] and IL-6 measured at T1 and T2 [(0.92 ± 0.16) ng/L, (27.93 ± 4.17) ng/L] were significantly lower compared with the control group ( t = 3.39, 6.96, 18.20, all P < 0.05). There were no significant differences in plasma level of malondialdehyde, arterial partial pressure of oxygen/inhaled oxygen fraction, numeric rating scale score, the incidence of complications, the incidence of re-operation, and the length of hospital stay between the two groups (all P > 0.05). Conclusion:Thoracic segment epidural anesthesia can reduce the local inflammatory response of the lung during lung cancer surgery.

Application value of different methods of segmented latissimus dorsi myocutaneous flap in repairing chest wall defect after local advanced breast cancer surgery (with video) / 中华内分泌外科杂志

Objective:To explore the application value of different methods of segmented latissimus dorsi myocutaneous flap in repairing chest wall defects after local advanced breast cancer surgery.Methods:The clinical data of 64 patients with unilateral locally advanced breast cancer admitted to Shanxi Cancer Hospital from Feb. 2019 to Jan. 2020 were selected. All patients underwent modified radical mastectomy for breast cancer. The patients were divided into two groups according to the random number table method. Antegrade (group A, n=32 cases) and retrograde (group B, n=32 cases) were used to design and cut the segmented latissimus dorsi myocutaneous flap to repair the defects. The range of skin island cut was 14 cm×6 cm-19 cm×7 cm; The donor area of the flap was closed directly. The application effects of the two groups of methods were compared. Results:In group A, one antegrade flap was partially necrotic, while in group B, six retrograde flaps were partially necrotic ( P>0.05). The delayed healing rate of donor site incision in group A was 6.25%, significantly lower than that in group B (25.00%) ( χ2=4.267, P=0.039). All the patients in both groups were followed up for 12 to 24 months, and the appearance and texture of the flaps were satisfactory; Only linear scar was left in the donor area, and the shoulder joint activity was not affected. The mean survival time was 20.8 months. Conclusion:The antegrade latissimus dorsi myocutaneous flap can repair the large area defect of chest wall after LABC, which can ensure the blood supply of the flap to the greatest extent, reduce the closing tension of the donor area, the incidence of postoperative complications, and promote the healing of the incision.

Objective:To investigate the current situation of health emergency response literacy among emergency nurses, analyze the potential profile of emergency nurses′ health emergency response literacy and explore the influencing factors of different categories, so as to provide reference for formulating targeted and specific training intervention programs.Methods:From September to October 2022, 386 emergency nurses from 5 tertiary A-level hospitals in Shandong Province were selected as the research objects by convenient sampling method. A cross-sectional survey was conducted by using the general information questionnaire, the Literacy Self-assessment Scale of Public Health Emergency Response In Nurses, the Chinese version of Modified Self-leadership Questionnaire, and Nurse Perceived Professional Value Scale. The latent profile analysis was carried out with the results of 3 explicit indexes of the Literacy Self-assessment Scale of Public Health Emergency Response In Nurses. At the same time, the influencing factors of different latent profiles of health emergency literacy were explored by univariate analysis and ordered multi-classification Logistic regression.Results:The health emergency literacy of emergency department nurses was divided into three latent profiles: high health emergency literacy type accounting for 45.4% (175/386), medium health emergency literacy type accounting for 41.5% (160/386), and low health emergency literacy type accounting for 13.1% (51/386). Ordinal Logistic regression showed that the main emergency work post was pre hospital first aid, participated in public health emergency rescue operations, self leadership, and professional value were protective factors of health emergency literacy (all P<0.05). Age≤25 years old and junior college degree were risk factors of health emergency literacy (both P<0.05). Conclusions:Nursing managers can implement personalized training and intervention strategies according to different demographic characteristics of the health emergency literacy of emergency nurses, develop self leadership improvement plans from individual and organizational factors, and actively cultivate their sense of professional value, in order to comprehensively improve the health emergency literacy of emergency nurses.

Risk factors and survival analysis of acute rejection in recipients after simultaneous pancreas-kidney transplantation / 中华器官移植杂志

Objective:To summarize the clinical characteristics and risk factors of acute rejection(AR)of transplanted pancreas and kidney after simultaneous pancreas-kidney transplantation(SPK)and explore the effects of AR on the survival of transplanted pancreas, kidney and recipients.Methods:From September 2016 to July 2022, the relevant clinical data were retrospectively reviewed for 218 recipients undergoing SPK.According to whether or not AR occurred after SPK, they were assigned into two groups of AR(n=53)and non-AR(n=165). The relevant clinical data were compared for two groups of donors and recipients and the risk factors of AR analyzed by binary Logistic regression.Kaplan-Meier method was employed for comparing the survival rates of recipients/transplanted pancreas and kidneys in two groups.Results:A total of 53 cases(24.3%)developed ARs of transplanted pancreas(n=31, 14.2%)(5 of 2 ARs), transplanted kidney(n=15, 6.9%)(1 of 2 ARs)and transplanted pancreas & kidney AR(n=11, 5.0%)(2 of 2 ARs). Tacrolimus blood levels in AR and non-AR groups were(5.8±1.2)and(6.3±1.6)μg/L and failed to attain targets in 36(67.9%)and 78(47.3%)cases.During follow-ups, the incidence of pneumonia and urinary tract infections in AR group versus non-AR group were[43.4%(23/53)vs.27.3%(45/165)and 39.6%(21/53)vs.18.8%(31/165)]and the differences were statistically significant( P=0.028 & 0.002). The results of multifactorial regression analysis revealed that sub-optimal blood level of tacrolimus was an independent risk factor for an occurrence of AR in grafts of SPK recipients( OR=2.254, 95% CI: 1.167-4.353, P=0.016). Comparisons of 1/5-year postoperative survival rates between recipients in AR and no-AR group(98.1% vs.93.9% and 92.1% vs.92.4%)indicated that the differences were not statistically significant( P=0.233 & 0.806). Through comparing 1/5-year survival rates of transplanted pancreas in AR and non-AR groups(94.3% vs.100%, 89.4% vs.98.6%), the differences were statistically significant( P=0.003 & 0.004). And 1/5-year survival rates of transplanted kidneys in AR and non-AR groups(92.5% vs.100% and 90.2% vs.100%)were compared and the differences were statistically significant(all P<0.001). Conclusions:The incidence of AR is higher in transplanted pancreas and kidney after SPK.And the incidence of pneumonia and urinary tract infection is higher in AR group than that in non-AR group.Sub-optimal blood level of tacrolimus is an independent risk factor for the occurrence of AR.The 1/5-year survival rates of transplanted pancreas and transplanted kidney are lower in AR group than those in non-AR group.It has some effect on the survival of transplanted pancreas and kidney.

Clinicians can use the drugs targeting abnormal indicators according to the results of this Bayesian network meta-analysis combined with the actual situation of patients to achieve better therapeutic effects.

Distribution and drug resistance characteristics of pathogens in recipients undergoing simultaneous pancreas-kidney transplantation / 器官移植

Objective To investigate the distribution and drug resistance characteristics of pathogens in donors and recipients undergoing simultaneous pancreas-kidney transplantation (SPK). Methods Clinical data of 231 pairs of donors and recipients undergoing SPK were analyzed retrospectively. The pathogens of samples from donors and recipients were identified by VITEK-2 analyzer, and drug sensitivity test was performed by K-B method. The source distribution and composition ratio of pathogens in donor and recipient samples, distribution characteristics of multi-drug resistant organism, infection of recipients and drug resistance characteristics of pathogens were analyzed. Results A total of 395 strains of pathogens were cultured from 1 294 donor samples, and the detection rate was 30.53%. Gram-negative bacteria mainly consisted of klebsiella pneumoniae, Gram-positive bacteria mainly comprised staphylococcus aureus, and fungi primarily included candida albicans, respectively. In total, 2 690 strains of pathogens were cultured from 10 507 recipient samples, and the detection rate was 25.60%. Gram-negative bacteria mainly consisted of pseudomonas maltophilia, Gram-positive bacteria primarily comprised enterococcus faecalis, and fungi mainly included candida albicans, respectively. Among 395 pathogens of donors, 15 strains of methicillin-resistant staphylococcus aureus (MRSA), 16 strains of extended-spectrum β-lactamase (ESBL) positive drug-resistant bacteria, 8 strains of carbapenem-resistant pseudomonas aeruginosa (CR-PA), 21 strains of carbapenem-resistant acinetobacter baumannii (CR-AB), 2 strains of carbapenem-resistant enterobacteriaceae (CRE) and 1 strain of multiple-drug/pan-drug resistant pseudomonas aeruginosa (MDR/PDR-PA) were identified. Among 2 690 strains of recipient pathogens, 73 strains of ESBL positive drug-resistant bacteria, 44 strains of CR-PA, 31 strains of CR-AB and 3 strains of MDR/PDR-PA were detected. One recipient developed donor-derived infection, 69 cases of pneumonia, 52 cases of urinary tract infection, 35 cases of abdominal infection and 2 cases of hematogenous infection were reported within postoperative 1 year. Gram-negative bacteria were resistant to certain antibiotics. Gram-positive bacteria were sensitive to vancomycin. Fungi were sensitive to amphotericin B. Conclusions Gram-negative bacteria are the main pathogens of SPK recipients, which are resistant to certain antibiotics. Empirical use of antibiotics can be delivered before culture results are obtained. Subsequently, sensitive antibiotics should be chosen according to the culture results to improve the survival rate of SPK recipients.

Prevention， Treatment， and Recuperation of Infection with SARS-CoV-2 Variants by Traditional Chinese Medicine Based on Idea of Epidemic Prevention of Jiangnan Medical School / 中国实验方剂学杂志

Because of the frequent occurrence of epidemics in Jiangnan since ancient times， the local medical schools have accumulated rich experience in epidemic prevention， among which Yushan medical school， Wumen medical school， and Qiantang medical school are famous. The physicians have inherited the theory in Treatise on Cold Damage Diseases and developed the therapies for febrile diseases. Adhering to the idea of integrating cold and febrile diseases， the physicians in Jiangnan flexibly adapt ZHANG Zhongjing's theory by combining regional climate， patient physique and other factors to explain the pathogenesis， which is of great significance for the prevention and treatment of epidemics. Therefore， traditional Chinese medicine （TCM） has demonstrated good curative effect on coronavirus disease-2019 （COVID-19） in China. However， the SARS-CoV-2 variants （Delta and Omicron） characterized by strong infectivity， pathogenicity， and immune escape capacity keep emerging， which bring great challenges to the global prevention and control of this pandemic. To this end， we studied the ways of Jiangnan medical school for the prevention and treatment of epidemics， reviewed the evolution of TCM treatment protocols for COVID-19， and summarized China's experience in fighting against the emerging SARS-CoV-2 variants. Further， we explored the measures of TCM in treating SARS-CoV-2 variants from prevention， treatment， and rehabilitation according to the theory for epidemic prevention of Jiangnan medical school. This paper provides reference for the prevention and treatment of emerging SARS-CoV-2 variant and facilitates the development of TCM epidemiology.

Over- and under-treatment of lung cancer / 中国胸心血管外科临床杂志

@#With the development and improved availability of low-dose computed tomography (LDCT), an increasing number of patients are clinically diagnosed with lung cancer manifesting as ground-glass nodules. Although radical surgery is currently the mainstay of treatment for patients with early-stage lung cancer, traditional anatomic lobectomy and mediastinal lymph node dissection (MLND) are not ideal for every patient. Clinically, it is critical to adopt an appropriate approach to pulmonary lobectomy, determine whether it is necessary to perform MLND, establish standard criteria to define the scope of lymph node dissection, and optimize the decision-making process. Thereby avoiding over- and under-treatment of lung cancer with surgical intervention and achieving optimal results from clinical diagnosis and treatment are important issues before us.

Clinical efficacy of surgical resection after conversion therapy for advanced gastric cancer / 肿瘤研究与临床

Objective@#To observe the clinical effect of surgical resection after conversion therapy for patients with advanced gastric cancer.@*Methods@#The clinical data of 23 patients with advanced gastric cancer who were admitted to Shanxi Provincial Cancer Hospital from January 2015 to October 2017 were retrospectively analyzed. All patients underwent multi-disciplinary treatment(MDT)-directed conversion therapy, and D2 radical gastrectomy was performed after the disappearance of non-healing factors. The remission of patients after conversion therapy and the related intraoperative and postoperative indicators were analyzed.@*Results@#After the conversion therapy, there were 2 cases (8.7%) of complete remission, 13 cases (56.5%) of partial remission and 8 cases (34.8%) of stable disease. The remission rate of the conversion therapy was 65.2% (15/23). In all 23 cases, the surgical time was (135.5±32.1) min, the intraoperative blood loss was (356.7±101.3) ml, the number of lymph nodes resected was 35.5±10.3. The time of gastric tube indwelling was (70.5±29.6) h, the time to first liquid intake was (85.0±21.5) h, the time of drainage tube placement was (196.2±36.2) h and the postoperative hospital stay was (10.7±3.2) d. After surgery, two cases had grade ⅢA post-operative complications and 2 had gradeⅡ. All patients were followed up, the median progression-free survival time was 13.5 months and the median overall survival time was 21.9 months.@*Conclusion@#The survival time of patients with advanced gastric cancer can be prolonged by D2 radical gastrectomy after the MDT-guided conversion therapy.

Analysis of risk factors for post-transplant diabetes mellitus in patients with renal transplants / 中华内分泌外科杂志

Objective@#To investigate the incidence and risk factors contributing to post-transplant diabetes mellitus (PTDM) in kidney transplant recipients within one year post-transplantation.@*Methods@#A total of 293 non-diabetic kidney transplant recipients were retrospectively analyzed. Patients were divided into non-PTDM group and PTDM group according to the diagnostic criteria of diabetes mellitus. The incidence of PTDM was calculated and the potential risk factors of PTDM were analyzed by univariate and multivariate Logistic regression analysis.@*Results@#Among the 293 non-diabetic patients, 36 patients developed PTDM within 1 year, with an incidence of 12.3%. Multivariate Logistic analysis showed that age (OR 1.055, 95% CI 1.014-1.098, P=0.009) , body mass index [odd ratio (OR) 1.231, 95% confidence interval (CI) 1.084-1.398, P=0.001], polycystic kidney as the primary disease (OR 1.508, 95% CI 1.006-2.262, P=0.047) , 2-hour postprandial blood glucose (OR 1.186, 95% CI 1.04-1.53, P=0.011) , HbA1c (OR 1.732, 95% CI 1.075-3.428, P=0.015) and 1-hour postprandial blood C-peptide (OR 0.869, 95% CI 0.804-0.939, P=0.001) were independent risk factors for PTDM in kidney transplant recipients within 1-year post-transplantation.@*Conclusion@#Patients with older age, obesity, polycystic kidney as the primary disease, higher level of HbA1c and 2-hour postprandial blood glucose, and lower level of 1-hour postprandial blood C-peptide may have higher risk of developing PTDM.

Distribution characteristics of pathogenic bacteria in infectious donors from organ donation after citizen's death and preventive strategies for renal transplant recipients: a single center experience / 器官移植

Objective To investigate the distribution characteristics of pathogenic bacteria in infectious donors from organ donation after citizen's death and preventive strategies for renal transplant recipients. Methods Clinical data of 412 donors and 803 recipients from organ donation after citizen's death were retrospectively analyzed. All donors underwent culture of airway secretions, urine, blood and renal lavage fluid. The incidence rate of infection, distribution and composition ratio of pathogenic bacteria of donors from organ donation after citizen's death were observed. The scores of all donors were evaluated according to the length of intensive care unit (ICU) stay for donors, the situation of abdominal trauma and the results of body fluid culture, etc. According to the score, the recipients received different infection prevention regimes. The incidence rate of donor-derived infection (DDI) and clinical prognosis of the recipients were analyzed. Results A total of 243 donors were diagnosed with infection in 412 donors from organ donation after citizen's death with an infection rate of 59.0%. In total, 456 strains of pathogenic bacteria were isolated, mainly derived from the airway secretions (71.7%). Gram-negative bacteria dominantly consisted of Klebsiella pneumoniae and acinetobacter baumannii. Gram-positive bacteria mainly included staphylococcus aureus and fungus mainly included yeast-type fungus. Three recipients (kidneys from 2 donors respectively) developed DDI with an incidence rate of 0.4%. Conclusions The infection rate of donors from organ donation after citizen's death is relatively high. It is effective to prevent the incidence of DDI by grading the risk of infection of donors and adopting rational preventive plan according to the score.
