Objective To investigate the potential effect of cetyltrimethyl ammonium bromide(CTAB)separated mannan of cell wall from Candida albicans on the production of IL -6and IL -8in h uman peripheral blood mononuclear cells(PBMC)induced by lipopoly saccharide(LPS).Methods PBMCs were pretreated with differen t concentrations of CTAB mannan(1.000mg /mL?0.100mg /mL?0.010mg /mL)for 24h.LPS(50?g /mL)was added and co-incubated for 24h.And a t 48h,the supernatants were collected.At 24h and 48h,only the super-natants of stimulated by CTABmannan were collected.LPS(50?g /mL)was the positive control,unstimula ted culture medium the negative control.The con tents of IL -6and IL -8in the supernatants were determined by ELISA.Re-sults At 24h and 48h,no IL -6and IL -8were detected in 3different concentration-CTAB mannan groups.LPS could induce IL -6(478.507?24.876ng /mL),IL -8(529.655?53.279ng /mL).The contents of IL -6and IL -8of negative control were not detectable.In 1.000mg /mL CTAB mannan +LPS group the contents of IL -6were(85.620?16.058ng /mL,P=0.004),IL -8were(123.940?20.319ng /mL,P=0.011).In 0.100mg /mL CTAB mannan +LPS group,IL -6(210.086?27.874ng /mL,P=0.007),IL -8(206.798?31.878ng /mL,P=0.022).In 0.010mg /mL CTAB mannan +LPS grou p,IL -6(201.387?32.396ng /mL,P=0.014),IL -8(203.133?36.012ng /mL,P=0.015).Conclusion CTAB mannan of cell wall from Candida albicans could downregulate the production o f IL -6and IL -8from human peripheral blood mononuclear cells induced by LPS.

A patient with intermittent right lumbar pain for more than one month and aggravating for one week was reported. The right laparoscopic radical nephrectomy was performed, and fibrosarcoma of the right kidney was diagnosed. The patient refused further radiotherapy or chemotherapy and was discharged on the 11th after surgery. One year after operation, the patient underwent chest CT, and subdural tumor of right lobe of liver was detected. A surgery was performed in another hospital, and liver metastasis from right renal fibrosarcoma was diagnosed. He was alive four months after operation.

Brainstem glioma is a kind of gliomas with focus in the brain stem. At present, surgery is still the preferred treatment for brainstem gliomas. Resection of brainstem gliomas, because of the special anatomical structure and important physiological function, results in extremely high mortality and disability rate, and choosing a reasonable surgical program can significantly improve the prognosis of patients. This article mainly discusses the safe entry zone and surgical approach of brainstem gliomas.

Objective To evaluate the efficacy and safety of biphasic insulin aspart 30 (BIAsp30)plus metformin in type 2 diabetes subjects switching from basal insulin plus oral antidiabetic drugs (OAD)Methods During 16 weeks, multiple-center, open-label, and single-arm study including 2 weeks of screening period,4 weeks of run-in period,and 16 weeks of treatment period were carried out. Subjects with type 2 diabetes mellitus inadequately controlled on basal insulin therapy with or without oral antidiabetic drugs were switched to twice-daily BIAsp30 plus metformin with dose titration to achieve fasting plasma glucose target. Results Of the 293 Chinese subjects exposed to trial drugs [age: ( 54.0±9.6 ) years, diabetes duration: ( 8.54±5.49 ) years, body mass index: (24.89±3.28)kg/m2, baseline HbA1c: 8.16% ±0.89%], 122 were previously treated with basal insulin analogues and 169 with human basal insulin. At end of the trial ,the mean reduction of HbA1 c was 1.30% ±0.96% (P＜0. 01 ). The proportion of patients achieved HbA1c＜7.0% and HbA1c ≤6.5% was 60.4% and 38.9% respectively. 8-point plasma glucose measurements showed significant improvements at all the time points examined ( all P＜0. 01 ) ,and the average value of all 8 points measured decreased from ( 10.53±2.58 ) mmol/L atbaseline to (7.79± 1.58 ) mmol/L at the end of treatment ( P＜0. 01 ), reduced by 2.76 mmol/L. Postprandial glucose increments were significantly reduced after breakfast ( -1.73 mmol/L,P＜0.01 )and dinner ( -1.28 mmol/L,P＜0.01 ), while no significant reduction was observed after lunch ( -0.09 mmol/L, P = 0. 734 5 ). No severe adverse effect and no major hypoglycemia were reported. The overall hypoglycaemia rate was 2.68 events/subject year. The average weight gain was (0. 76 ±0. 14 )kg (P＜0. 0l ). Conclusion Twice-daily BIAsp30 plus metformin is effective and safe to type 2 diabetic subjects inadequately controlled on basal insulin treatment.BIAsp30 treatment should be considered for type 2 diabetic subjects who have unsatisfactory response to previous basal insulin treatment.

A female patient who was admitted to the hospital on March 4, 2020 due to the right kidney mass for 4 days by physical examination. Ultrasound examination revealed a single space-occupying lesion in the right kidney, and further examination of the abdominal enhanced CT and three-dimensional reconstruction showed two lesions in the right kidney. The retroperitoneal laparoscopic partial nephrectomy was carried out. The pathological diagnosis were renal leiomyoma and renal eosinophiloma, respectively. After 1 year follow-up, no recurrence or metastasis was found.

The segmental testicular infarction rate is extremely low, usually showing acute testicular pain, which needs to be distinguished from testicular tumor, testicular torsion, etc. Only a few cases were reported. In this study, two cases were presented. Case one, a 13-year-old boy, was admitted to hospital due to right testicular swelling and pain for 3 days. Presenting with vomiting once on May 5, 2017.He underwent right scrotum exploration and testicular fixation. Testicular pain was disappeared and discharged on the five days operation. There was no obvious abnormality in color doppler ultrasound after one year after operation. Another patient, a 26-year-old man, was admitted to hospital due to left testicular swelling and pain for 6 on March 15, 2018. He was treated with Xue Saitong, natra heparin calcium and Maizhiling tablets. After seven days of treatment, the testicular pain improved and were discharged. One month after discharge, the patient had no pain or discomfort, and the color Doppler ultrasound showed that the left subtesticular polar-like low-isoecho, and a small amount of star-like blood flow signal around.

Objective    To review and analyze the clinical manifestations of common aortitis in cardiac surgery. Methods    We screened 41 552 patients who were hospitalized in the Department of Cardiac Surgery of Zhongshan Hospital, Fudan University from 2010 to 2020, analyzed the patients' clinical data, and classified according to the type of diseases. Then we summarized all their clinical manifestations. Results    In our center 145 patients were operated for aortitis diseases, including 75 males and 70 females, with the age of 24-76 (45.6±11.3) years. There were 61 patients of Takayasu's arteritis, 51 patients of Behcet's disease, 8 patients of syphilitic aortitis, 8 patients of systemic lupus erythematosus, 2 patients of Kawasaki disease, 4 patients of ankylosing spondylitis, 10 patients of dry syndrome, and 1 patient of scleroderma. Conclusion    Aortitis is not uncommon in cardiac surgery, and awareness of the disease should be enhanced. So that we can distinguish various types of aortitis and to make proper management to improve patients' prognosis.
