Objective:To evaluate clinical prognosis and prognostic factors of patients with early stage (Ⅰ stage) and locally advanced (Ⅱ/Ⅲ stage) lung cancer treated with carbon ion radiotherapy (CIRT).Methods:Clinical data, treatment, adverse reactions, survival and so on of 54 lung cancer patients who received CIRT and follow-up in the Heavy Ion Center of Wuwei Cancer Hospital of Gansu Province from March 2020 to September 2022 were retrospectively analyzed. The survival curve was plotted using Kaplan-Meier method. Difference tests were performed using log-rank test. Logistic regression analysis was used to identify prognostic factors.Results:According to inclusion and exclusion criteria, 54 patients were enrolled in the study, including 10 patients with early stage lung cancer and 44 patients with locally advanced lung cancer. The median follow-up time for 10 patients with early stage lung cancer was 11.0 (6.75, 17.25) months, and the median dose of irradiation was 60 Gy [relative biological effect (RBE)]. Upon the last follow-up, 3 patients had complete response (CR) and 3 patients had partial response (PR). Four patients had stable disease (SD) and no progressive disease (PD). The 1-year and 2-year local control rates (LCR), progression-free survival (PFS) rates and overall survival (OS) rates were 100%. During treatment and follow-up, 2 patients developed grade 1 radiation pneumonia, 1 case of grade 2 radiation pneumonia, 1 case of chest wall injury (chest wall pain), and there were no adverse reactions greater than grade 2. The median follow-up time of 44 patients with locally advanced stage was 12.5 (4.25, 21.75) months, and the median irradiation dose was 72 Gy (RBE). Thirty-two (73%) patients received concurrent chemotherapy during treatment, 20 (45%) patients received sequential chemotherapy after treatment, 14 (32%) patients received immune maintenance therapy and 3 (7%) patients obtained PD and received targeted drugs. Upon the last follow-up, 3 (7%) patients had CR, 17 (39%) patients had PR, 19 (43%) patients obtained SD, and 5 (11%) patients had PD. The 1-year and 2-year LCR were 96.0% and 87.3%, 90.9% and 84.1% for the 1-year and 2-year PFS rates, and 93.2% and 86.4% for the 1-year and 2-year OS rates, respectively. The median OS and PFS of patients were not reached. Multivariate logistic regression analysis showed that maintenance therapy after radiotherapy ( P=0.027) and clinical target volume (CTV) irradiation volume ( P=0.028) were the factors affecting PFS. Simultaneous chemoradiotherapy ( P=0.042) and maintenance therapy after radiotherapy ( P=0.020) were the factors affecting OS. And gross tumor volume (GTV) ≥215 ml ( P=0.068) might be an independent risk factor for grade 2 and above radiation pneumonia. Conclusions:The domestic carbon ion system has definite clinical effect and controllable toxic and side effects in the treatment of early stage and locally advanced lung cancer. The combination of synchronous chemotherapy and further maintenance treatment can significantly improve clinical prognosis of patients without significantly increasing the risk of toxic and side effects.

Pathological insulin resistance (IR) is closely related to gestational diabetes mellitus (GDM) and adverse pregnancy outcomes in women with GDM. Increasing studies have investigated the efficacy of IR indices, such as quantitative insulin sensitivity index, homeostasis model assessment of insulin resistance, triglyceride-glucose index and sex hormone-binding globulin, in predicting GDM and related complications in recent years. This article reviews the research progress in the above topics.

Objective:To compare the adverse reactions, efficacy and survival rate of carbon ion beam irradiation in the elective lymph node (ENI) drainage area of locally advanced non-small cell lung cancer (LA-NSCLC) with relative biological effect (RBE) dose of 48 Gy using 16 and 12 fractions.Methods:A total of 72 patients with pathologically confirmed LA-NSCLC admitted to Wuwei Heavy Ion Center of Gansu Wuwei Tumor Hospital from June 2020 to December 2021 were enrolled and simple randomly divided into groups A and B, with 36 patients in each group. Patients in groups A and B were treated with carbon ion beam irradiation to the lymph node drainage area with 48 Gy (RBE) using 16 and 12 fractions. The acute and chronic adverse reactions, efficacy and survival rate were observed. The survival curve was drawn by Kaplan-Meier method. Difference test was conducted by log-rank test.Results:The median follow-up time was 13.9 (8.8-15.7) months in group A and 14.6 (6.3-15.9) months in group B. Sixteen (44.4%) patients were effectively treated in group A and 9 (25%) patients in group B. Thirty-four (94.4%) cases achieved disease control in group A and 30 (83.3%) cases in group B. Statistical analysis showed that the overall survival rate in group B was similar to that in group A ( χ2=1.192, P=0.275). Comparison of planning parameters between two groups showed CTV volume, D mean, V 5 Gy(RBE), V 20 Gy(RBE) and V 30 Gy(RBE) of the affected lung, cardiac V 20 Gy(RBE), V 30 Gy(RBE) and D mean, esophageal V 30 Gy(RBE), V 50 Gy(RBE), D max and D mean, D max of the trachea and spinal cord had no significant difference (all P>0.05). No grade 3 or 4 adverse reactions occurred in the enrolled patients during treatment and follow-up. No statistical differences were observed in the acute radiation skin reaction ( χ2=5.134, P=0.077), radiation esophagitis ( χ2=1.984, P=0.371), and advanced radiation pneumonia ( χ2=6.185, P=0.103) between two groups. Conclusions:The two dose fractionation modes of carbon ion therapy system are equally safe in the mediastinal lymphatic drainage area of LA-NSCLC, and the adverse reactions are controllable. The long-term efficacy still needs further observation.

Objective:To explore the relationship between 18F-fibroblast activation protein inhibitor (FAPI)-42 SUV max of primary gastric cancer and clinicopathological factors of patients. Methods:Fifty-one patients (31males, 20 females, age: 51(47, 65) years) with gastric cancer who underwent 18F-FAPI-42 PET/CT before surgical resection in Nanfang Hospital, Southern Medical University from February 2022 to January 2023 were analyzed retrospectively. The clinicopathological factors that might affect tumor SUV max (including gender, age, tumor location, pathological type, histological grade, Lauren classification, vascular and(or) neural invasion, programmed cell death-ligand 1 (PD-L1) expression, pathologic(p)T stage, pN stage and pTNM stage) were evaluated by the univariate analysis (Mann-Whitney U test or Kruskal-Wallis rank sum test) and multivariate analysis (multiple linear regression analysis). Results:The sensitivity of 18F-FAPI-42 PET/CT in the diagnosis of patients with primary gastric cancer was 82.35% (42/51). The diagnostic sensitivities for early gastric cancer (T1) and locally advanced gastric cancer (T2-T4) were 59.09%(13/22) and 100%(29/29), respectively. The SUV max of primary lesion was 4.90(1.71, 12.51). The univariate analysis showed that SUV max of primary gastric cancer was related to tumor location ( z=-2.00, P=0.046), pT stage ( H=36.94, P<0.001), pN stage ( z=-3.89, P<0.001), pTNM stage ( H=31.49, P<0.001) and vascular and(or) nerve invasion ( z=-5.22, P<0.001), but not related to pathological type, histological grade, Lauren typing, and PD-L1 expression ( z values: from -1.78 to -0.09, all P>0.05). pT stage was found to be a significant independent factor for SUV max in primary gastric lesion by multivariate analysis ( t=2.52, P=0.015). Conclusions:The 18F-FAPI-42 SUV max of primary tumor was related to tumor location, pT stage, pN stage, pTNM stage, and vascular and(or) nerve invasion; pT stage is an independent factor affecting tumor SUV max. The ability of 18F-FAPI-42 PET/CT to detect gastric cancer is mainly affected by pT stage.

Objective:To integrate the best evidence of non-drug intervention of urinary incontinence in elderly women and to formulate practical recommendations.Methods:In this systematic review study, using “elderly woman”,“urinary incontinence”,“bladder training”,“pelvic floor muscle training”,“enuresis”,“leakage of urine” as the key words, the 6S evidence resource pyramid model was used to search in British Medical Journal best practice, Uptodate, World Health Organization, Guidelines International Network, National Institute for Health and Care Excellence, Chinese Medical Association, Scottish Intercollegiate Guideline Network, Registered Nurses Association of Ontario, Cochrane Library, The Joanna Briggs Institute (JBI), New Zealand Guidelines Group, Polish Society of Gynecologists and Obstetricians, PubMed, Embase, Medline, Web of Science, SinoMed, China National Knowledge Infrastructure, WanFang Data, etc. The evidence retrieved included evidence-based knowledge base resources, clinical practice guidelines, expert consensus, systematic review, etc. Data were retrieved from January 1, 2017 to May 1, 2022, and collated from May 2, 2022 to May 25, 2022. Two researchers independently evaluated the quality of literature and extracted data using the AGREE Ⅱ and JBI evidence-based health care center assessment tools. The JBI evidence-based health care center′s evidence pre-rating system and evidence recommendation rating system were applied to rank the evidence; and under the guidance of the evidence structure of JBI, the strength of evidence recommendation was determined and the best evidence was extracted and summarized in combination with the study group discussion and expert opinion.Results:A total of 9 articles were retrieved, including 7 guidelines and 2 systematic reviews; and 6 guidelines were classified as Grade A and 1 as grade B; both 2 systematic reviews were rated as Grade A; 84% (27/32) of the items were evaluated as “Yes”. Evidence were summarized as 34 pieces of best evidence from 6 dimensions, including “overall recommendation, evaluation of type and degree of urinary incontinence, lifestyle change, behavioral therapy, prevention of precipitating factors, intervention in special population”; the flow chart of screening, evaluation, special symptoms, life style and behavior therapy was combed, and the practical suggestions were formed.Conclusions:The overall quality of the literature on non-drug intervention of urinary incontinence in elderly women is high, and the level of evidence is high. Early identification of urinary incontinence types and assessment of disease severity, lifestyle changes, avoidance of predisposing factors and behavioral therapy are the key to non-drug treatment of urinary incontinence in those patients.

Parkin, an E3 ubiquitin ligase, plays a role in maintaining mitochondrial homeostasis through targeting damaged mitochondria for mitophagy. Accumulating evidence suggests that the acetylation modification of the key mitophagy machinery influences mitophagy level, but the underlying mechanism is poorly understood. Here, our study demonstrated that inhibition of histone deacetylase (HDAC) by treatment of HDACis activates mitophagy through mediating Parkin acetylation, leading to inhibition of cervical cancer cell proliferation. Bioinformatics analysis shows that Parkin expression is inversely correlated with HDAC2 expression in human cervical cancer, indicating the low acetylation level of Parkin. Using mass spectrometry, Parkin is identified to interact with two upstream molecules, acetylase acetyl-CoA acetyltransferase 1 (ACAT1) and deacetylase HDAC2. Under treatment of suberoylanilide hydroxamic acid (SAHA), Parkin is acetylated at lysine residues 129, 220 and 349, located in different domains of Parkin protein. In in vitro experiments, combined mutation of Parkin largely attenuate the interaction of Parkin with PTEN induced putative kinase 1 (PINK1) and the function of Parkin in mitophagy induction and tumor suppression. In tumor xenografts, the expression of mutant Parkin impairs the tumor suppressive effect of Parkin and decreases the anticancer activity of SAHA. Our results reveal an acetylation-dependent regulatory mechanism governing Parkin in mitophagy and cervical carcinogenesis, which offers a new mitophagy modulation strategy for cancer therapy.

Objective:To study the clinical characteristics of neonatal sepsis caused by raoultella ornithinolytica.Methods:From January 2010 to December 2020, clinical data of seven cases of neonates with raoultella ornithinolytica sepsis in the Department of Neonatology of our hospital were analyzed. Literature published from the establishment of the databases to December 31, 2020 were searched and reviewed on this topic. The databases included PubMed, Web of Science, Embase database, Wanfang Database, CNKI, National Science and Technology Library and Chinese Science Paper Online.Results:Among the 7 cases admitted to our hospital, 6 male and 1 female, 6 premature and 1 full-term small-for-gestational-age (SGA), 6 patients presented with lethargy, 5 patients had fever and 3 showed dyspnea. 4 patients had necrotizing enterocolitis (NEC), 1 congenital intestinal malrotation, 1 congenital jejunal atresia, 1 intestinal adhesion and stricture. 4 patients had history of surgery. Leucocytosis was found in 3 cases and leukopenia in 1 case. Thrombocytopenia and increased inflammatory indicators were found in all cases. All 7 patients recovered and were discharged. 4 articles on 4 newborn cases (3 males, 1 female including two premature infants) were found for literature review. 3 cases had skin flushing, 3 cases showed dyspnea, 2 cases had fever and 1 case presented with lethargy. 1 case received surgery for congenital heart disease. Leucocytosis was found in 2 cases, leukopenia in 1 case, thrombocytopenia in 2 cases and elevated inflammatory indicators in 3 cases. 1 patient died due to septic shock and the other three recovered and were discharged.Conclusions:Raoultella ornithinolytica neonatal sepsis may occur in infants with intestinal comorbidities, history of invasive procedures, premature birth or full-term SGA and congenital malformations. Most anti-infective therapies are effective. However, if the patient had septic shock, the prognosis is poor.

Objective:To observe the changes of the structure and visual function of the retina in patients with or without the ectopic inner foveal layers (EIFL) and to explore the factors influencing the recovery of visual function in patients with idiopathic epimacular membrane (IMEM).Methods:A retrospective clinical study. From March 2015 to June 2019, 90 patients with MEM who were diagnosed by Ophthalmic Center of the Second Hospital of Hebei Medical University were enrolled in the study. All patients were examined by best corrected visual acuity (BCVA) and frequency domain optical coherence scan. BCVA was recorded by Snellen vision table, and it was converted into the minimum resolution angle logarithm (logMAR) vision. Among 90 eyes, IMEM grade 2-4 was 68 (75.6%, 68/90), 18 (20.0%, 18/90), 4 (4.4%, 4/90), respectively. According to this, the grade 2 was set as group A, and the grade 3 and grade 4 were combined to group B. There was no significant difference in age ( t=0.015), sex composition ratio of patients between two groups ( χ2=0.060) and the average of central macular thickness (CMT) ( F=2.277) ( P=0.904, 0.809, 0.141). The difference of average logMAR and BCVA was statistically significant ( F=35.913, P=0.000). All patients underwent 25G pars plana three channel vitrectomy with simultaneous removal of epiretinal membrane and internal limiting membrane. BCVA, CMT and improvement of IMEM grading were observed at 1, 3, 6 and 12 months after operation. BCVA, EIFL thickness and CMT were compared before and after operation by single factor repeated variance analysis; Fisher exact probability method was used to compare the changes of the anatomical structure of the eyes in the two groups at 12 months after operation. Results:1, 3, 6, 12 months after operation, the average eyes of logMAR BCVA in group A were 0.50±0.13, 0.38±0.12, 0.27±0.12, 0.19±0.10. The patients in group B were 0.66±0.14, 0.60±0.13, 0.54±0.14, 0.52±0.14. CMT in group A were 364.82±81.29, 281.65±72.45, 228.55±55.34, 182.84±56.13 μm. The patients in group B were 455.88±69.60, 440.18±68.65, 383.76±65.38, 371.39±66.60 μm. The difference was statistically significant in the two groups (BCVA: F=37.913, 11.479, 24.250, 39.013; P=0.000, 0.002, 0.000, 0.000. CMT: F=10.987, 39.610, 55.789, 79.987; P=0.002, 0.000, 0.000, 0.000). In group A, IMEM was improved to 57 eyes of grade 1 on 12 months after operation. Among the 18 eyes in group B, IMEM was improved to 1 and 3 eyes in level 1 and level 2, respectively, and no improvement was found in 4 eyes in grade 4. The difference was statistically significant ( P=0.000) in the improvement of the number of eyes in the two groups. Conclusions:The patients with IMEM without EIFL have better visual prognosis and reversible anatomical changes. EIFL is an important factor affecting the visual function and anatomical structure recovery after operation.
