Glia maturation factor(GMF)detected in the adult brain is an acidic proteinthat has the ability to promote the morphological and chemical differentiation ofastroblasts,but this effect is reversible.In the present study we have establishedneuron-enriched dissociated primary cultures from 7-day-old rat cerebellar cortexin which about 97% of the cells are neurons especially granule cells using differential count of indirect immunofluorescence.The addition of purified GMF to the culturesmarkedly enhances neuronal survival,while control cultures grown in the absence ofGMF exhibit a significant decrease in neuronal number.These GMF effects aredose-dependent,with optimal stimulation occurring at a concentration of 250 ng/ml.Although the mechanism by which purified GMF influences cerebellar corticalneuronal survival is not known,these results suggest that GMF not only affectsglial cells,but also may function as a neurotrophic agent in the central nervousmetsys

Objective To analyse the effects of anastomat to the resection surgery in 1800 esophageal and gastric cardiac carcinoma patients. Methods The Esophagus-gaster and Esophagus-intestine were stapled by anastomat in the cervical region in 182 cases、 intrathoracically in 1296 cases and intraperitoneal in 322cases. The occurrence of complications caused by anastomat, including anastomotic fistula,anastomotic stricture,anastomotic bleeding and mechanical failure,were observed. Results Anastomotic fistula occurred in 15 cases ( 15/1800,0.83% ,ten cases took Shanghai-made GF-I anastomat ,five cases took YH-W single disposable single anastomat ), among which 6 cases had the cervical anastomosis; Anastomotic stricture occurred in 41 cases ( 41 /1800,3.11%, fifteen cases took Shanghai-made GF-I anastomat, twenty-six took YH-W single disposable single anastomat) ,but all of them recovered after dilatation; Anastomotic bleeding occurred in 21 cases (21/18001.16%, thirteen cases took Shanghai-made GF-I anastomat, eight took YH-W single disposable single anastomat) ;Anastomat mechanical failure in operation occurred in 14 cases( 14/1800,0. 78% ,ten cases took Shanghai-made GF-I anastomat, four took YH-W single disposable single anastomat). Conclusion Anastomat is an effective method in reducing the postoperational complications of esophageal and gastric cardiac carcinoma resection. Disposable single anastomat has higher clinical value.

Objective To explore the expression of transient receptor potential channel 6(TRPC6)in human breast cancer cells, and to clarify the correlation of TRPC6 with the invasion potential of breast cancer cells. Methods The human breast cancer cell strains MCF-7 (hypo-invasion group)and MDA-MB-231 (hyper-invasion group)were cultured.The expressions of TRPC6 mRNA and protein in in two groups were detected by RT-PCR and Western blotting methods.Then the MDA-MB-231 cells were divided into control group and SKF96365 group, the effects of SKF96365 on the invasion ability of MDA-MB-231 cells invitro were explored by wound healing assay and Transwell experiment.Results The results of Western blotting and RT-PCR showed that the expression levels of TRPC6 mRNA and protein in MDA-MB-231 cells were higher than that in MCF-7 cells(P<0.05).The wound healing assay showed the numbers of migrating cells in 5,25 and 40μmol·L-1 SKF96365 groups (76.24±7.54, 45.33±4.50,25.12±1.57)were lower than those in control group (130.48±9.55)(P<0.05).The Transwell experiment results indicated that the invasiveness of MDA-MB-231 cells were inhibited significantly by SKF96365 compared with control group (P<0.05).Conclusion The invasion ability of human breast cancer MDA-MB-231 cells is promoted by upregulating the TRPC6 expression, which indicates that the TRPC6 may play role in the metastasis of human breast cancer.

Objective:To investigate the safety and effectiveness of tension adjustment technique using anatomical landmarks during retropubic midurethral synthetic sling.Methods:The data of 36 consecutive female patients with urinary incontinence, who had underwent retropubic midurethral synthetic sling procedure from January to August 2019 were analyzed retrospectively. The mean age was (60.83±7.93) years old and the body mass index was (24.43±2.44) kg/m 2. Among the recruited subjects, 36 had positive stress test and Marshall-Marchetti test. 20 (55.6%) were pure stress urinary incontinence, and 16 (44.4%) were mixed urinary incontinence. The severity of incontinence was classified into mild (5 cases, 13.9%), moderate (14 cases, 38.9%), severe (13 cases, 36.1%) and very severe (4 cases, 11.1%) using one-hour pad tests. Urodynamics were performed in 17 cases, with 5 (29.4%) presented detrusor overactivity, 3 (17.7%) possessed intrinsic sphincter deficiency. For each case, the tension of the sling was adjusted based on the anatomical landmarks, i. e. using an angled clamp attached closely to the pubic symphysis ventrally and the tip parallel to the edge of hymen dorsally. All patients were catheter-free right after the procedure. The subjective and objective effectiveness, and safety (the rate of urinary retension after surgery and postvoid residual volume 3 months later) were evaluated.The subjective cure rate was was defined as complete leakage free or very mild leakage during excessive bladder filling and fierce cough. The subjective effectiveness was defined as over 50% improvement of the leakage symptom. The objective cure rate was defined as a negative stress test. Results:For all 36 patients, the median hospital stays was 8 (5-95)h. No bladder perforation or transfusion cases. All patients were catheter-free right after the procedure, with no incidence of urinary retention. 27 patients completed a 3-month follow-up, with 22 had post-void residual data, 23 had subjective effectiveness data and 23 had objective effectiveness data. The median post-void residual was 7.5 (5-64) ml, subjective cure rate was 91.3% (21/23), and objective cure rate was 95.7% (22/23). 8.7% (2/23) reported difficult urination alleviated without the necessity of clinical interference. No urethra erosion or vagina extrusion was found. At 2-year follow-up, 34 patients completed assessment by phone. The subjective cure rate was 91.2% (31/34), with only 2.9% (1/34) reported difficult urination. Besides, at 3-month follow-up, there was no difference regarding the subjective cure rate [100.0%(12/12) vs. 81.8%(9/11)]or objective cure rate [91.7%(11/12) vs. 100.0%(11/11)] between patients with stress and mixed incontinence. No difference was noted among patients with mild, moderate, severe and very severe leakage[75.0% (3/4) vs. 100.0%(6/6) vs. 90.0%(9/10) vs. 100.0%(3/3)]. Of the 12 cases with urodynamic records, the presence of detrusor overactivity [66.7%(2/3) vs. 88.9%(8/9)] or intrinsic sphincter deficiency [0(0/1) vs. 90.9%(10/11)] did not significantly affected the cure rate of the procedure. At 2-year follow-up, there was no difference regarding the subjective cure rate between patients with stress and mixed incontinence [94.7%(18/19) vs. 86.7%(13/15)]. No difference was also noted among patients with mild, moderate, severe and very severe leakage[80.0%(4/5) vs. 100.0%(13/13) vs. 83.3%(10/12) vs. 100.0%(4/4)]. Of the 16 cases with urodynamic records, the presence of detrusor overactivity [60.0%(3/5) vs. 90.9%(10/11)]or intrinsic sphincter deficiency [66.7%(2/3) vs. 84.6%(11/13)]did not significantly affected the cure rate of the procedure.Conclusions:Tension adjustment using anatomic landmarks during sling procedure is safe and feasible for urinary incontinence, with minimum complications and residual volume, and high subjective/objective cure rate.

【Objective】 To explore the efficacy of retropubic midurethral synthetic sling (RMUS) in relieving urgency and urge urinary incontinence (UUI) symptoms in patients with mixed urinary incontinence (MUI). 【Methods】 Clinical data of 44 female MUI patients treated with RMUS during Jan.2018 and Dec.2020 in Shanghai Renji Hospital were retrospectively analyzed.All patients had positive results in stress test and Marshall-Marchetti test before operation, and 27 of them completed ICIQ-FLUTS-LF questionnaire.Urodynamic (UDS) tests suggested that 9 patients (20.5%) presented detrusor overactivity (DO).During RMUS procedure, the tension of the sling was adjusted based on the anatomical landmarks.The postoperative efficacy and improvement of urinary incontinence were analyzed. 【Results】 The patients aged (58.59±9.08) years, with a body mass index of 24.71±2.77.Among the 40 patients who completed telephone interview 2 years after surgery, the subjective cure rate was 85.0% (34/40).Among the 27 patients with records of questionnaires before and after surgery, there were significant differences in the incidence of urine leakage \[100% (27/27) vs. 18.5% (5/27)\], stress urinary incontinence (SUI) \[100% (27/27) vs. 18.5% (5/27)\] and UUI \[70.4% (19/27) vs. 29.6% (8/27)\] (P<0.05).However, no statistical differences were found regarding nocturia voiding episode (≥1 times), urgency, dysuria, hesitancy, strain to void, intermittent stream and enuresis (P>0.05).Based on preoperative UDS test, there were significant differences regarding the subjective cure rate in patients with or without preoperative DO \[55.6% (5/9) vs. 93.5% (29/31)\], incidence of SUI \[66.7%(4/6) vs. 4.8% (1/21)\], and UUI \[66.7% (4/6) vs. 19.0% (4/21)\] (P<0.05), while there was no statistical difference regarding urgency \[66.7% (4/6) vs. 33.3% (7/21)\] (P>0.05). 【Conclusion】 RMUS is effective in treating MUI patients with positive stress test and Marshall-Marchetti test results, which can relieve SUI and UUI symptoms, but has no effects on urgency symptoms.DO on preoperative urodynamics results in poorer subjective outcomes.
