Purpose:To investigate the mechanisms,susceptibility,prevention and treatment of the tumor patients'renal function,which was injured by the Body Gama Kinfe treatment.Methods:There were 7 patients,who had been observed for the effect of hydration,vaso-dilation,diuresis,basifying urine,anti-coagulation,detocifiation,even hemodialysis.Results:All patients' renal function gradually recovered.Conclusions:The tumour patients' renal function can be acutely injured by Body Gama Kinfe treatment.The patients who were elderly or inherent in renal failure would be prone to injary.In general we could improve the situation by better prevention,early-diagnosis,efficient treatment,so that we can not only alleviate the injuries,but also speed recovery,thus achieving better prognosis.

Objective To study the significance of c-met mRNA in axillary drainage after operations for breast cancer. Methods RT-PCR assay was used to examine c-met mRNA in axillary drainage after operations in 52 cases of breast cancer. The relationships between the expression of c-met and the tumor size, metastatic lymph nodes, the expressions of estrogen receptor (ER), progesterone receptor (PR) and c-erbB-2 were analyzed, respectively. In addition, the effect of douching operative field with 5-FU and distilled water on the expression of c-met mRNA was also analyzed. Results ①The proto-oncogene c-met mRNA could be detected in axillary drainage after operations for breast cancer by RT-PCR, and its positive rate was higher than that in routine pathological detection for micrometastasis in the axillary lymph nodes (P

Objective To compare the initial detection rate and the accuracy of qualitative diagnosis of multislice spiral computed tomography (MSCT),gastrointestinal tract radiography,gastroscopy,and endoscopic ultrasonography in the diagnosis of gastric lipoma,with a focus on evaluating the diagnostic value of MSCT.Methods Twenty-six patients with gastric lipoma,6 males and 20 females with a mean age of 61 years (ranging from 41 to 82 years) and confirmed by pathology,were enrolled in the present study.Their clinical,pathologic and imaging findings were retrospectively analyzed.All the patients underwent gastroscopy,and plain and dynamic enhanced MDCT scans.Of them 21 cases underwent endoscopic ultrasonography and 12 cases gastrointestinal tract radiography.Results The detection rate was 88.5％(23/26) and 80.8％(21/26),P＞0.05 for MSCT and gastroscopy,respectively,in the initial diagnosis of gastric lipomas,both higher than that of gastrointestinal tract radiography (41.7％,5/12).The accuracy of qualitative diagnosis of MSCT (100％,23/23) was higher than that of endoscopic ultrasonography (71.4％,15/21),gastrointestinal tract radiography (0％,0/5) and gastroscopy (0％,0/21).The lesions located at the gastric antrum in 18 cases (69.2％,including 10 front wall,6 posterior wall and 2 pyloric canal),the gastric body in 7 cases (26.9％) and the gastric fundus in 1 case (3.8％).All the lipomas presented as round or ovoid nodule with clear boundary on MSCT images,and homogeneous or mixed low density.The CT values,long dimensions and volumes ranged from-50 to-95Hu (mean-72.58Hu),5.7 to 40.7mm (mean 17.67mm) and 0.02 to 7.03cm3 (mean 1.89cm3),respectively.Contrast-enhanced CT scans showed no enhancement in all the lesions.Conclusion MSCT can make accurate locating and qualitative diagnosis for gastric lipomas.

Objective To investigate the effect of berberine on endoplasmic reticulum stress PERK apoptosis pathway in HK-2 cells by high fructose.Methods HK-2 cells were grown in DMEM/F12, containing 10% fetal bovine serum (FBS) and divided randomly into four groups: normal control group (Group C); Fructose group (Group F): it contains 25mmol/L fructose culture; Berberine group (Group B): 25mmol/L fructose + 10μmol/L berberine treatment group; TUDCA group (Group T):25mmol/L fructose +2μmol/L TUDCA culture group; Cells were collected after culturing 24h. The expression of glucose-regulated protein 78 (GRP78), CHOP protein and the phosphorylation levels of PERK, eIF2α were tested by Western blotting. The cell cycles were detected by flow cytometry and the apoptosis of cells were detected by TUNEL staining.ResultsWestern blotting showed that the expression of GRP78 and CHOP protein in group F was significantly higher than that in group C, and the levels of p-PERK and p-eIF2α in group F were significantly higher than those in group F. Compared with group F, GRP78, CHOP, p-PERK and p-eIF2α in group B and T were significantly lower (P<0.05). The expression of GRP78, CHOP, p-PERK and p-eIF2α in group B had no significant difference. Flow cytometry and TUNEL staining showed that the cell viability of fructose group was significantly lower than that of C group, and the apoptotic index was significantly higher than that of group C (P<0.05). Compared with group F, the activity of HK-2 cells in group B and T significantly increased, otherwise the apoptosis index significantly decreased, and the difference was statistically significant (P<0.05). Compared with group T, the viability index and apoptosis rate of group B had no significant difference (P>0.05).Conclusion Persistent high fructose can activate the intracellular PERK pathway in HK-2 cells, causing endoplasmic reticulum stress. Berberine can inhibit the fructose-induced PERK and eIF2α phosphorylation, down-regulated the expression of GRP78, CHOP protein, thus by regulating PERK Pathways to alleviate cell cycle arrest and reduce cell apoptosis.

Closed-loop hospital management can effectivly cope with the COVID-19 pandemic. In order to ensure the continuity of treatments for hemodialysis patients under closed-loop management and minimize possible medical and infection risks, Huashan Hospital affiliated to Fudan University and 9 hospitals in Shanghai established a hemodialysis alliance in January 2021.The alliance optimized hemodialysis resources within the region through overall planning by preparing sites, materials and personnel shifts in advance, and establishing management systems and work processes to ensure that patients could be quickly and orderly diverted to other blood dialysis centers for uninterrupted high-quality hemodialysis services, in case that some hemodialysis centers in the alliance under closed-loop management.From November 2021 to April 2022, 317 of 1 459 hemodialysis patients in the alliance were diverted to other centers for treatment, accumulating 1 215 times/cases of treatments without obvious adverse reactions. The practice could provide a reference for medical institutions to quickly establish mutual support mode under major public health events.
