Objective:To explore the safety and short-term efficacy of single-port robotic transanal total mesorectal excision (SPr-taTME).Methods:The retrospective and descriptive study was conducted. The clinicopathological data of six patients who underwent SPr-taTME at Daping Hospital of Army Medical University from October to November 2024 were collected. There were 3 males and 3 females, aged (65±5)years. Observation indicators: (1) intraoperative situations; (2) postoperative situations; (3) follow-up. Measurement data with normal distribution were represen-ted as Mean± SD, measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers. Results:(1) Intraoperative situations. All patients successfully underwent SPr-taTME without conversion to laparotomy or blood transfusion. There was no intraoperative complication such as accidental hemorrhage or adjacent organ injury. No intra-operative adverse events or mortality occurred. The operation time of the 6 patients was 286(range, 240?400)minutes. The time of transanal platform setup and robotic docking was (21±10)minutes, transanal dissection time was (97±45)minutes, and transabdominal dissection time was (90±35)minutes. The volume of intraoperative blood loss was (47±14)mL. Among the six patients, 1 case underwent synchronous transanal and transabdominal surgery, while 5 cases underwent non-synchronous procedures. Specimens were extracted transanally in 5 cases and via an auxiliary abdominal incision in 1 case. The single-port robotic platform was utilized for the abdominal surgery in 3 cases, while laparoscopy was used in 3 cases. Splenic flexure mobilization was performed in 3 cases and omitted in the other 3 cases. Three patients underwent hand-sewn sigmoid colon-anal anastomosis, 1 case underwent modified Bacon pull-through anastomosis, 1 case received stapled sigmoidorectal anastomosis, 1 case underwent sigmoid colostomy without anastomosis due to significant bowel edema. Two cases didn′t undergo intestinal stoma, 2 cases underwent virtual ileostomy, 1 case underwent ileostomy, and 1 case underwent sigmoid colostomy. (2) Postoperative situations. All patients started water drinking and out‐of‐bed activities on postoperative day 1 and liquid diet intake on postoperative day 2. The time to postoperative first flatus was 1(range, 1?3)days, and duration of postoperative hospital stay was (8±2)days.The total number of lymph nodes dissected was 13±2, with the number of positive lymph nodes as 0(range, 0?3) and the distance of distal resection margin as (23±8)mm. Pathological examination of 6 patients showed 1 case in stage T1N0, 2 cases in stage ypT0N0, 1 case in ypT1N0, 1 case in ypT3N1, and 1 case in ypT0N1. The degree of mesorectal integrity was complete in 5 patients and nearly complete in 1 patient. The surgical specimens of 6 patients showed negative in distal, proximal and circumferential margin. (3) Follow-up. All 6 patients completed the 30-day postoperative follow-up. None of the patients experienced postoperative complication such as bleeding, intestinal obstruction or anastomotic leakage. There was no readmission within 30 days after surgery. Digital rectal examination or colonoscopy on postoperative 30 day confirmed no anastomosis-related complications, including stenosis, dehiscence or anastomotic leakage. All 6 patients survived.Conclusion:The SPr-taTME is safe and feasible, with satisfactory short-term efficacy.

OBJECTIVE To optimize β-cyclodextrin(β-CD)inclusion process of Cinnamomi Ramulus Formula Granules vola-tile constituents by orthogonal test,based on standard relation and information entropy method.METHODS On the basis of single factor experiments,the ratio of β-CD to aromatic aqueous solution,the inclusion temperature,and the inclusion time were selected as the investigating factors;the inclusion rate,drug loading,and standard relation of cinnamic aldehyde in inclusion complex were used as the evaluation index.The information entropy method was used to determine the weight coefficient of each index,then the comprehen-sive score was calculated,the inclusion process conditions were optimized by orthogonal experiment.The inclusion complex was charac-terized by thin layer chromatography,ultraviolet absorption spectroscopy,Fourier infrared spectroscopy,and X-ray diffraction.RE-SULTS The best inclusion process was that the ratio of β-CD to aromatic aqueous solution was 3∶100(g·mL-1),the inclusion temperature was 50℃,and the inclusion time was 1 h.The average inclusion rate of the obtained inclusion compound was 80.84%,the drug loading was 8.63%,and the standard relation was 0.91.The results of thin-layer chromatography,ultraviolet,infrared spec-troscopy and other characterization experiments showed that the volatile components in the aromatic aqueous solution successfully en-tered the β-CD cavity,and the inclusion complex was successfully prepared.CONCLUSION The optimum inclusion process is sta-ble and feasible,which can provide references for the preparation process of Cinnamomi Ramulus Formula Granules.

Objective To explore the predictive value of gait and balance on the frailty in community-dwelling older adults aged 65 years and older in Shanghai. Methods A total of 414 community-dwelling older adults aged 65 years or older were recruited from Shanghai,from De-cember,2022 to April,2023.They were investigated with Fried's Frailty Phenotype Scale,Timed Up and Go Test(TUGT),one leg standing test(OLST)and self-designed questionnaire.The factors related to frailty were ana-lyzed using multivariate Logistic regression. Results The prevalence of pre-frailty and frailty were 62.8%and 10.9%,respectively.Living in rural residence,older age,low income,smoking,sedentary lifestyle and no regular exercise were the risk factors for frailty among com-munity-dwelling older adults.Time of TUGT increased,and time of closed eyes OLST descreased respectively in the frail older adults(P<0.05).The area under curve was 0.846(95%CI 0.808 to 0.884,P<0.001)as prediction for frailty using the combination of TUGT and closed eye OLST,with a sensitivity of 0.726 and a specificity of 0.817 at the optimal threshold. Conclusion Gait and balance may be a valuable predictor of frailty in community-dwelling older adults in Shanghai.

This case report described a 61-year-old woman who presented with dizziness, headache, muscle ache, diplopia, and vomiting who lost consciousness. Upon hospital admission, the levels of high-sensitivity cardiac troponin I and partial pressure of carbon dioxide were increased markedly. Loss of consciousness occurred twice after removal of invasive ventilator support. Coronary angiography demonstrated no stenosis in coronary arteries. Ultrasonography revealed inactivity of respiratory muscles. Oculomotor disturbance and autonomic-nerve dysfunctions were observed. Serum antibody against glutamic acid decarboxylase was positive. The rare phenotypes of persistent stiffness of muscles in the neck, face, bilateral upper and lower limbs were observed. The patient was diagnosed with fulminant myocarditis complicated by Stiff-person syndrome. Immunomodulatory treatment (glucocorticoids and immunoglobulins) elicited satisfactory therapeutic effects. In this case report, it was found that fulminant myocarditis and Stiff-person syndrome shared a common pathogenesis: "cytokine storm". Such patients may benefit from early treatment with immunomodulatory agents.

Objective:To analyze the changing trend of intracerebral hemorrhage (ICH) incidence among residents with different characteristics during 9 years of comprehensive hypertension prevention and control (hypertension prevention and control) in Tengzhou from 2013 to 2021.Methods:From January 1, 2013 to December 31, 2021, the new ICH cases collected by the Center for Disease Control and Prevention in Tengzhou City were analyzed to calculate the incidence of ICH, and the trend of its distribution was analyzed among residents with different ages, sexes, and between urban and rural areas. The registered population information came from Tengzhou Public Security Bureau. Age and sex standardized incidence was calculated based on the 7th National Population Census in 2020. The Cochran-Armitage test was used to analyze the time and age trends of the incidence.Results:The overall ICH crude and standardized incidence in Tengzhou City decreased from 97.30/100 000 to 52.13/100 000 ( Z=-9.93, P<0.001) and 119.30/100 000 to 50.69/100 000 ( Z=-15.40, P<0.001) from 2013 to 2021, and both elevated to form a single peak in 2020, with 22.58% ( χ 2=24.02, P<0.001) and 18.09% ( χ 2=17.08, P<0.001) higher than in 2019, respectively. The trends in male and female incidence over the same period were similar to the overall trends, and the incidence was higher in males than in females in all years. The incidence of ICH increased with age in all years. The difference of increase in male incidence rate in 2020 was statistically significant in three age groups ≥45 years compared with 2019 (36.29%, 23.57% and 16.18%, respectively, χ 2=6.73, 4.65, 4.00, P<0.001). The incidence of ICH decreased by 70.07% and 36.23% ( Z=18.44, 5.22, P<0.001) in urban and rural areas respectively from 2013 to 2021, whereas increased by 34.15% ( χ 2=10.88, P<0.01) and 22.08% ( χ 2=18.63, P<0.001) in 2020 compared with 2019 separately. Conclusions:The incidence of ICH in Tengzhou from 2013 to 2021 showed a significant downward trend, with the decrease in the incidence of ICH in women exceeding that in men. The decrease in the incidence of ICH in urban areas exceeded that in rural areas, and male morbidity seemingly had a younger trend.

Objective:To explore the application of failure mode and effects analysis (FMEA) in low-energy X-ray intraoperative radiotherapy (IORT), analyze its potential risks in IORT, and preliminarily explore the feasibility of FMEA in optimizing IORT management and reducing the occurrence of potential risks.Methods:An FMEA working group was established by the IORT team (1 radiologist, 1 radiology physicist, 2 surgeons, and 2 nurses) to apply the FMEA methodology to conduct a systematic risk assessment. The process modules were established, the potential failure modes and causes for each module were analyzed, the severity (SR), frequency of occurrence (OR) and likelihood of detection (DR) of failure modes were scored and the risk priority number (RPN) was calculated: RPN= SR × OR × DR. The possible errors and potential clinical impact of each part of the radiotherapy process were prospectively analyzed and understood, the causes and current measures were analyzed for each failure mode and preventive measures were proposed and risk management measures were taken accordingly.Results:The IORT process was divided into 8 modules with 14 failure modes. The highest OR value was unsatisfactory target area confirmation (7 points), the highest SR value was equipment failure to discharge the beam (10 points), the highest DR value was wrong key entry after dose calculation (7 points), the highest RPN values were unsatisfactory target area confirmation (210 points) and ineffective protection of endangered organs (180 points). Weaknesses were corrected according to priorities, workflows were optimized and more effective management methods were developed.Conclusion:FMEA is an effective method of IORT management and contributes to reducing the occurrence of potential risks.

To report a case of neonatal succinate-CoA ligase deficiency with mild methylmalonic aciduria caused by SUCLG1 compound heterozygous mutation. Our proband developed the disease at the 2nd day of life, manifested by vomiting and milk rejection. Blood gas analysis indicated metabolic acidosis and hyperlactacidemia. Laboratory tests showed mild hyperammonemia, mild elevation of serum aminotransferase and normal homocysteine. Imageology examination showed brain dysplasia and multiple cardiac malformations. Mild methylmalonic aciduria was suggested by blood acylcarnitines and urine organic acids analysis. Two novel mutations, c.40A>G (p.M14V) and a heterozygous deletion of exon 6 to 9, were identified by whole-exome sequencing in SUCLG1, which came from the mother and father, respectively. Metabolic acidosis turned better by volume expansion and acidosis correction, but lactic acidosis was persistent. Edema and respiratory failure occurred, after which the parent gave up treatment and the patient died after discharged from hospital. The mutations of SUCLG1 gene lead to succinate-CoA ligase deficiency and mitochondrial DNA depletion syndrome. There is no specific treatment for this disease. For infants with feeding difficulties, lactic acidosis and multiple organ damage, metabolic abnormality screening should be performed. Genetic analysis is the diagnostic method.
