ObjectiveWE transfected the recombinant expression plasmid of pcDNA3. 1-HIF-1α into the prostate cancer cells, to research the effect of HIF-1α on proliferation of prostate cancer cell PC-3.MethodsWe selected a stable expression cell line with G418 were selected by transfection of the recombinant expression plasmid of pcDNA3. 1-HIF-1α into the prostate cancer. The protein and mRNA expression of HIF-1α was assayed by western - blot and RT-PCR. The cells growth curves were described by MTT and the ability of invasion was assayed by Transwell.ResultsThe expression of HIF-1α mRNA was not obviously increased compared to the untransfected prostate cancer cell by RT-PCR, but the expression of HIF-1α protein was up-regulated by western-blot after the recombinant expression plasmid transfected into PC-3. The ability of cell proliferation and invasion was significantly enhanced by MTT and Transwell assays.ConclusionThe stable expression cell model of HIF-1α was successfully constructed, which enhanced the proliferation and invasion of prostate cancer cell PC-3.

BACKGROUND: Removal of immunosuppressants in patients with recurrent tumor in long-term following organ transplantation is always a hot controversial point in academic circles. To further elevate clinical efficiency, people began to invent new immunosuppressant and studied immune efficiency of various immunosuppressant component. They tried to reduce the application of cyclosporin A (CsA).OBJECTIVE: To analyze the CsA safe withdrawal of a case of kidney recipients, at 18 years after renal transplantation, who developed bladder carcinoma and renal pelvic carcinoma at 11 years and 18 years after transplantation, respectively. METHODS: After identified diagnosis, we performed transurethral resection of bladder tumor (TURBt) and total nephroureterectomy merobladder excision. Pathologic examination revealed grade Ⅰ-Ⅱ of bladder and renal pelvic transitional cell carcinoma. After the operation, patient was treated with immune suppression program of CsA withdrawal gradually in 12 days.Within 12 days, 5 mg CsA was decreased every 3 days, and complete withdrawal was done at 12 days. The dosage of azathioprine tablets and prednisone acetate tablets was not changed. Serum creatinine levels were rechecked every 3 days during drug withdrawal, and blood pressure, urine volume, physical symptom of patients and ultrasound of transplanted kidney were observed.RESULTS AND CONCLUSION: During the three months of CsA withdrawal, the blood creatinine levels were from 65 to indicated that the CsA gradually withdrawal of a case of kidney recipients after renal transplantation, who developed transitional cell carcinoma and was performed transurethral resection of bladder tumor (TURBt) and total nephro- ureterectomy merobladder excision, was safe. No tumor relapse or diversion was found.

OBJECTIVE: Tacrolimus is widely used in organ transplant. However, the long-term effects of tacrolimus on Asian, in particular in Chinese people, are few. The aim of this study is to evaluate the efficacy and safety of long-term curative effect of tacrolimus used in kidney transplantation patients in China.DATA SOURCES: Electronic and manual retrieve of Medline database, Chinese journal full-text database, Cochrane library, and CEBM/CCD, and relevant medical journals in China were applied.DATA SELECTION: Published randomized controlled trials on tacrolimus in kidney allograft recipient were retrieved, and the data were underwent Meta analysis. Odds ratio (OR) and its 95% confidence interval (CI) were used as the measurement parameter of efficacy comparison. The statistical analyses were performed using Stata software.MAIN OUTCOME MEASURES: ①The survival ratio of patient/kidney after 1 year. ②The survival ratio of patient/kidney after 3 years. ③Rejection ratio after 3 years. ④Infection rate after 3 years. ⑤Incidence of liver dysfunction after 3 years. ⑥Blood glucose disorder after 3 years.RESULTS: A total of 3 trials were eligible for the inclusion efficacy, including 3 Chinese trials and 0 foreign trials. Results of meta-analysis indicated that tacrolimus prevented the recipients of kidney transplantation from rejection effectively in three years [OR=0.40, 95%CI (0.27-0.61), P < 0.000 1]. Tacrolimus prevented the recipients of kidney transplantation from impaired liver function in three years [OR=0.28, 95%CI (0.15-0.52), P < 0.000 1]. No statistical difference of the 1-year and 3-year survival rate of patients/ kidney was found in the patients between group tacrolimus and group cyclosporine. Statistical difference of blood glucose disorder were found in the patients between group tacrolimus and group cyclosporine [OR=2.39, 95%CI (1.41-4.05), P=0.001].CONCLUSIONS: Tacrolimus prevented the recipients of kidney transplantation from rejection and impaired liver function effectively in three years in China. No statistical difference of the 1-year and 3-year survival rate of patients/kidney was found in the patients between two groups. In addition, the main side effect of tacrolimus is blood glucose elevation.

Objective: To investigate the effect of space glucose control (SGC) on the quality of blood glucose management in ICU patients with stress hyperglycemia. Methods: A prospective, cross-controlled, quasi-trial was conducted to observe patients with ICU-induced stress hyperglycemia between January 2018 and January 2019. Patients with conventional blood glucose management served as the control group, and SGC blood glucose management was used as the intervention group. The enrolled patients were interchanged between the two groups every 24 h, and the end point was 96 h. The differences in blood glucose management quality indicators between the two groups were compared, including the average blood glucose level, the highest and lowest blood glucose level, the average blood glucose monitoring interval, and the accumulated insulin dosage. SPSS 23.0 was used to analyze the data. The paired t test was used for the normal distributed data. Otherwise, two nonparametric correlation sample tests was used. A P<0.05 was considered statistically significant. Results: A total of 41 patients enrolled in this study during the study period. The average blood glucose value in the intervention group was significantly lower than that in the control group [(8.60 ±1.42)mmol/L vs (10.02 ±1.49)mmol/L, P< 0.01]. The frequency of hyperglycemia was lower than that of the control group (16.59 ±8.56 vs 18.73 ±7.91, P=0.023). The frequency of blood glucose value in the target blood glucose range was significantly higher than that of the control group (53.07±19.11 vs 29.44±19.60, P< 0.01). However, the frequency of hypoglycemia, the frequency of blood glucose monitoring and the accumulated insulin dosage in the intervention group were higher than those in the control group [1 (0, 5) vs 0 (0, 2), P< 0 01; 1 36 ±0 23 vs 1 89 ±0 28, P< 0.01; and (139.61 ±77.06)U vs (107.49 ±64.41)U, P<0.01]. Conclusions SGC can optimize the control of blood glucose in the target blood glucose range, but it can easily lead to mild hypoglycemia, and to a certain extent increases the workload of medical staff.

Objective To investigate the effects of butylphthalide injection on cerebral blood flow (CBF) perfusion and cognitive function in patients with acute cerebral infarction accompanied by cognitive disorder.Methods From September 2016 to September 2017,80 patients with acute cerebral infarction and cognitive impairment were admitted to the Department of Neurology,Yan'an Hospital of Kunming Medical University.They were assigned to an observation group (n=40) and a control group (n=40).The control group received conventional treatment while the observation group received butylphthalide injection in addition to conventional treatment.The treatment lasted for 14 days for both groups.Before and after treatment,dynamic susceptibility contrast-enhanced perfusion-weighted imaging (DSC-PWI) was used to measure the CBF parameters in the cerebral ischemic region,and Montreal Cognitive Assessment (MoCA) was used to evaluate the changes in cognitive function.Results After treatment,rCBF and rCBV increased significantly and rMTT and rTTP decreased significantly in the observation group (P＜0.05).After treatment,there were significant improvements in MoCA subscores and total score in the observation group (P＜0.05).In the observation group,the post-treatment increases in rCBV and rCBF were positively correlated with increased MoCA total score (r=0.474,P=0.013;r=0.282,P=0.027),and the post-treatment decreases in rMTT and rTTP were negatively correlated with increased MoCA total score (r=-0.294,P=0.021;r=0.382,P=0.019).Conclusion Butylphthalide injection can safely improve CBF perfusion in the focal region and cognitive function in patients with acute cerebral infarction,with no obvious adverse reactions.

Descriptive research methods were used to conduct in-depth interviews over the patients and record the results, and content analysis was employed to organize and analyze the data.Results:Four themes were refined: suffering from changes in body image; constantly facing the puzzles of diet management; gradually choosing to give up rehabilitation exercise; and feeling emotional fluctuations, the hardship of seeking medical service and inner expectations.Conclusions:Medical staff should pay attention to the true feelings of patients' home rehabilitation post operation, strengthen the professional support outside the hospital for the health-related problems and different mental states during the rehabilitation process, provide standardized home care services, and improve the quality of life of the patients.

Objective: To make etiological diagnosis and evaluate the protective effects of post-exposure prophylaxis(PEP) in an event of one dog injured seven persons. Methods: Direct immunofluorescence assay (DFA) and nested polymerase chain reaction (PCR) were employed to detect nucleoprotein and nucleoprotein(N) gene of rabies virus in the brain tissues of the dog, the positive samples were sequenced for the full length of N gene of rabies virus, then the homology of the N gene of rabies virus was analyzed after the phylogenetic tree was constructed. Rapid fluorescent focus inhibition test (RFFIT) was applied to detect the rabies virus neutralizing antibodies(RVNA) on day 0, 14 and 40 after PEP. Results: The cerebral, cerebellar and hippocampal tissues were positive by DFA and nested PCR. The phylogenetic tree indicated the rabies virus belonged to the rabies virus genotype I. The homology of the nucleotide and amino acid of the rabies virus N gene were over 86% with the vaccine strains. The titer of the RVNA increased significantly from the day 0 to day 14 after PEP, the lowest was 5.78 IU/ml and the highest was 26.15 IU/ml. On the day 40, the highest RVNA titer was 51.96 IU/ml. No rabies cases occurred in a one year follow-up visit. Conclusions Normative PEP can effectively prevent the occurrence of rabies cases.
