Objective:Exploring the clinical characteristics and treatment outcomes of tailgut cysts, and improving the understanding of this disease.Methods:A retrospective analysis of 42 patients with tailgut cyst surgically treated from Jan 2012 to Mar 2024 was conducted.Results:This study included 42 patients (28 females,14 males) with a median age of 51 (23-76)years old. Nineteen cases of perineal/abdominal pain, 13 cases of perianal swelling, 10 cases of perianal abscess, 7 cases of sacrococcygeal sinus, and 4 cases of anal mass were observed. These symptoms often occurred simultaneously. All 42 patients had lesions located behind the rectum, with a relative position to the coccyx (7 above the coccyx, 17 below the coccyx, 11 above and between the coccyx levels, and 7 horizontally).Tailgut cysts were located in the pelvic floor, with 3 cases above the levator ani muscle, 17 cases below the levator ani muscle, and 22 cases between the levator ani muscle levels. Forty-one cases were treated with posterior approach, and 1 case was treated with combined approach. Thirty-two were unilocular and 10 multilocular. Female patients with multiple compartments were significantly more common than males ( P<0.05), while tumor location, tumor size, recurrence, and malignancy were all independent of gender. After surgery, 8 cases (19％) experienced recurrences and 5 cases of malignant transformation patients had a long term multiple relapses. Conclusions:Tailgut cysts are rare,while women were common seen.Non-specific symptoms of pain in the perineum or abdomen, perianal swelling or abscess, are usually observed. In addition, multiple relapses could have malignant transformation. Surgical complete resection is the most reasonable treatment method and the appropriate surgical path should be selected based on the size, location, and relationship with adjacent tissues of the tumor.

Anxiety and depression are prevalent conditions in the geriatric department, leading to significant patient suffering and imposing substantial economic and social burdens.The incidence of anxiety and depression has been on the rise.Currently, the primary treatment approaches encompass drug therapy, physical therapy, and psychological intervention.However, due to the fact that most elderly individuals are unable to tolerate the side effects of medications and have low acceptance of psychological interventions, these treatment options alone are not sufficient for addressing anxiety and depression in this population.As a result, exercise therapy has emerged as a recommended treatment method in both domestic and international guidelines.This approach offers several advantages, including fewer side effects, cost-effectiveness, and controllable implementation.Nevertheless, it is crucial to develop an appropriate exercise prescription that encompasses the specific type, intensity, frequency, and duration of exercises.This paper aims to discuss the effect of exercise therapy, including exercise type, intensity, and frequency, as well as the mechanism of exercise intervention.

Objective In order to understand the distribution and drug resistance of the extended-spectrumβ-lactamase-producing (ESBLs) Enterobacteriaceae in female vaginal secretions and to provide the basis for clinical treatment.Methods 939 strains of Enterobacteriaceae isolated from female vaginal secretions were collected from Obstetrics and Gynecology Hospital of Fudan University from January 2014 to December 2017.The strain identification and drug sensitivity test of VITECK 2 Compact-totally automatic bacterial identification analyzer were used to analyze the detection rate and drug resistance of ESBLs Enterobacteriaceae.Results 257 strains of ESBLs-producing strains were detected in 939 strains of Enterobacteriaceae with a detection rate of 27％, including 220 Escherichia coli, 34 Klebsiella pneumoniae, 2 Stink-nose Klebsiella and 1 strain of Acidogenic Klebsiella.ESBLs Escherichia coli and Klebsiella pneumoniae were all resistant to Ampicillin and Cefazolin, and to Ceftazidime, Nitrofurantoin, SMZ, Amikacin, Ciprofloxacin, Gentamicin, tobramycin, Ampicillin/Sulbactam, Ceftriaxone, Ertapenem, Piperacillin/Tazobactam, Aztreonam, Cefepime, Levofloxacin the drug resistance rates of were 36％and 44％, 2％ and 41％, 67％ and 68％, 2％ and 15％, 58％ and 38％, 51％ and65％, 14％and 26％, 65％and 76％, 99％and 97％, 0％and 29％, 0％and 3％, 50％and 65％, 26％and 18％, 57％ and 32％, but they are all sensitive to Imipenem and Cefotetan.Conclusion The inicdence of ESBLs Enterobacteriaceae in female vaginal secretions is high, and Imipenem, Cefotetan, Piperacillin/Tazobactam have high antibacterial activity, which can be used as the experience of initial treatment.

Objective To summarize the CT features of pulmonary mucormycosis in post hematopoietic stem cell transplantation (HSCT) patients with leukemia,to provide timely and accurate guidance for clinical treatment.Methods 9 pulmonary mucormycosis in post HSCT patients with leukemia confirmed by surgery,biopsy and sputum culture were analyzed retrospectively.Distribution,morphology and CT features of the disease were analyzed and summarized.All patients were underwent non-enhanced MSCT.Results Reversed halo sign (n=7);patchy ground glass opacity (GGO) (n =5);bilateral multiple pulmonary nodules and nodular GGO (n=3);bilateral multiple pulmonary micro-cysts with spiculate boundary (n=1);pleural effusion (n=2);pneumo-mediastinum (n 1) were seen.Two or more than two CT signs were seen in some patients.The interval time between the appeared reversed halo sign and the transplantation were 0.5-19 months in 7 patients,which median time was 10 months and 6 cases (85.7％) appeared within 18months.8 patients (88.9 ％) presented cough,expectorated white or yellow phlegm,among them,4 cases (50 ％) presented bloodstained sputum or hemoptysis.3 cases (37.5 ％) presented left chest pain.1 case was asymptomatic.6 patients (66.7 ％) presented significant increased body temperature with the range from 38.4 ℃ to 39.6 C,the median was 39 C.3 patients (33.3％) showed normal temperature.The WBC counting was between 0.16-3.31 × 109/L,the median was 0.7 × 109/L.The neutrophil cell counting was between 0-2.46 × 109/L,with the median of 0.09 × 109/L.Among them,7 patients (77.8％) found reversed halo sign with neutrophil counting between 0-1.63 × 109/L,and the median was 0.09 × 109/L.Conclusion Various imaging manifestations of pulmonary mucormycosis are seen in post HSCT patients with leukemia.When patients is in agranulocytosis phase after transplantation HSCT,it is highly suggested pulmonary mucormycosis infection when the characteristic reversed halo sign is found.

Objective To compare the effects of propofol-and sevoflurane-based anesthesia on postoperative cognitive dysfunction in elderly patients undergoing cardiac valve operation under cardiopulmonary bypass (CPB).Methods Eighty patients of both sexes,of American Society of Anesthesiologists physical status Ⅱ or Ⅲ,aged 65-72 yr,weighing 60-80 kg,scheduled for elective cardiac valve operation under CPB,were randomly divided into 2 groups (n =40 each) using a random number table:propofol-based anesthesia group (group P) and sevoflurane-based anesthesia group (group S).In group P,propofo] was given by target-controlled infusion with the target plasma concentration of 0.5-2.0 μg/ml to maintain anesthesia.In group S,0.5％-2.5％ sevoflurane was inhaled for maintenance of anesthesia.Immediately after induction of anesthesia,at the end of operation,and at 6,12 and 24 h after operation,blood samples were taken from the superior vena cava for determination of plasma matrix metalloproteinase-9,S100β protein and neuron-specific enolase concentrations.Cognitive function was assessed at 1 day before operation,and at 3,7 and 30 days after operation.Results Compared with group P,the plasma matrix metalloproteinase-9,S100β protein and neuron-specific enolase concentrations at the end of operation and at 6 h after operation and incidence of postoperative cognitive dysfunction were significantly increased in group S (P ＜ 0.05).Conclusion Propofol-based anesthesia provides better cerebral protection than sevoflurane-based anesthesia,and the development of postoperative cognitive dysfunction is decreased in elderly patients undergoing cardiac valve operation under CPB.

Objective To compare the cerebral protective effect of propofol and sevoflurane combined with sufentanil anesthesia in the patients undergoing valvular surgery under cardiopulmonary bypass (CPB).Methods Sixty American Society of Anesthesiologists physical status Ⅱ or Ⅲ patients, aged 60-70 yr, scheduled for elective valvular surgery under CPB, were randomly divided into either propofol-based anesthesia group (group PA) or sevoflurane-based anesthesia group (group SA) , with 30 patients in each group.From induction of anesthesia to the end of surgery, group P received targetcontrolled infusion of propofol 0.5-2.0 μg/ml, and group S continuously inhaled 0.5％-2.5％ sevoflurane.Bispectral index value was maintained at 45-55.Immediately after induction (T0), at the end of surgery (T1) , and at 6, 12 and 24 h after surgery (T2-4) , the superior vena cava was retrogradely cannulated for blood sampling, and the concentrations of plasma S-100β protein and neuron-specific enzyme were determined using enzyme-linked immunosorbent assay.Results Compared with group SA, the plasma S-100β concentrations at T1,2 and neuron-specific enzyme concentrations at T1-3 were significantly decreased in group PA.Conclusion The cerebral protective effect of propofol combined with sufentanil anesthesia is superior to that of sevoflurane combined with sufentanil anesthesia in the patients undergoing valvular surgery under CPB.

Objective To investigate the correlation between stenosis of middle cerebral artery (MCA) and cerebral perfusion in patients with unilateral MCA stenosis.Methods Computed tomography perfusion (CTP) was performed in 34 patients with unilateral MCA stenosis,admitted to our hospital trom April 2012 to March 2013.The CTP parameters of mean transit time,cerebral blood flow,cerebral blood volume and time to peak were measured in regions supplied by anterior cerebral artery,MCA and posterior cerebral artery.All patients were divided into severe stenosis group and moderate stenosis group; the correlation between MCA stenosis and cerebral perfusion was analyzed.Results A decreased perfusion was detected in 25 patients (73.5％),and it was more likely found in the severe stenosis group (18/20,90％) than that in the moderate stenosis group (7/14,50％,P=0.017).The degree ofMCA stenosis was positively correlated with the changes of cerebral perfusion (r=0.381,P=0.026).The ratio of patients with transient ischemic attack (TIA) between the normal cerebral perfusion group and decreased cerebral perfusion group had statistical difference (11.11％ vs.72.00％,P=0.004).Conclusion Cerebral perfusion is significantly correlated with the severity of MCA stenosis in unilateral MCA stenosis patients; the proportion of TIA in the low cerebral perfusion patients is higher than that in the normal cerebral perfusion ones.

Objective To investigate the correlation between the unilateral middle cerebral artery (MCA)stenosis ratio and cerebrovascular reserve(CVR) using computed tomography perfusion (CTP) and CO2 inhalation test in patients with unilateral middle cerebral artery stenosis.Methods CTP were performed in 31 patients who were diagnosed as unilateral middle cerebral stenosis before and after CO2 inhalation.The basal ganglia and radial dimension were selected as interested regions (thickness 8 mm).The value of cerebral blood flow (CBF) was measured and the mean CBF values of all interested regions in each MCA territory were harvested separately.Then the CVR of each MCA territory was calculated according to the following formula:CVR =(CBF after CO2 inhalation test-CBF before CO2 inhalation test)/ CBF before CO2 inhalation test × 100％.Patients were divided into two groups:the severe stenosis group and the moderate stenosis group.The association between the MCA stenosis ratio and the CVR values was investigated.Results In 31 patients,different changes of CBF were found in affected MCA territory after CO2 inhalation.CBF increased in 17 cases,unchanged in 2 cases and decreased in 12 cases.A decreased CVR was detected in 51.6％ of the patients(16/31) and more likely found in the severe stenosis group (13/19) than that in the moderate stenosis group(3/12,P =0.029).The degree of stenosis in MCA was also significantly correlated with the changes of CVR(r =0.423,P =0.018).Conclusions CVR is decreased in some patients with unilateral MCA stenosis and significantly correlates with the severity of stenosis in MCA.
