Results A higher positive rate and stronger expression of TGF-?1 mRNA in SD skin lesions were seen, compared with those in controls(P0.05).The higher positive rate and stronger expression of TGF-?1 mRNA than TGF-?2 mRNA in SD were seen(P

Objective To explore the correlation between prostate neuroendocrine cells and chronic prostatitis via substance P (SP) detection.Methods Forty SPF-level SD male rats in two months old were randomized into two groups:the chronic prostatitis model group and the control group,20 in each.The model was induced by castration surgery under aseptic condition and post-castration injection of 17-β estrogen for 1 month duration.The control group was done by injection of 0.9％ NS without castration surgery.Making sure that the chronic prostatitis model was made successfully,then SP quantification in the 2 groups was analyzed via ELISA and immunohistochemical staining.Results The difference of SP in the 2 groups was significant (P =0.009) and SP was expressed highly in the model rats compared with controls.Conclusion The relationship between prostate neuroendocrine cells and chronic prostatitis is notable,maybe they participate in progress of chronic prostatitis.

Objective To study the effect and prognosis of multiple channels percutaneous renal ureteral calculi removal in the treatment of patients with complex renal calculi.Methods One hundred and forty-four cases patients with complex renal calculi accepted treatment in Dongda Hospital of Shanxian County from June 2012 to March 2015 for research.According to the random number table method,the patients were divided into the observation group and the control group,72 cases in each group.The single channel type was used in the control group,while multi-channel type operation was use in the observation group.Indicators related to the operation,stones clearance rate,changes in the degree of hydronephrosis,and the major complications after treatment of the two groups were compared.Results The operation time of the observation group was (104.82 ±8.54) min,significantly longer than that of the control group ((90.23 ±7.68) min),but the duration of hospital stay,fistulation tube indwelling time and the residual stone surface area were (6.84±1.25) d,(5.23±2.16) d and (223.16± 113.49) mm2 respectively,significantly less than that of the control group ((8.33±2.13) d,(6.74 ± 2.19) d and (429.54 ± 107.88) mm2 respectively),the differences were statistically significant(P =0.000).The stone removal rate of the observation group was 86.11％ (62/72),significantly higher than that of the control group(72.22％ (52/72)),the difference was statistically significant (P =0.040).There was no significant difference in terms of the total stone clearance rate and the degree of kidney water after treatment between the two groups (P＞0.05).The total complication rate of the observation group was 11.11％(8/72),of the control group was 9.72％ (7/72),and the difference was not statistically significant(P ＞0.05).Conclusion The efficacy of multi-channel operation for complex renal calculi is better,safe and feasible,but should reduce the number of channels as much as possible,so as to reduce the damage to patients effectively.

Objective To observe the curative effect of low melocular weight heparin(LMWH) on the hypercoagulability in acute Kawasaki disease(KD).Methods Forty-six patients were diagnosed KD.Twenty-two cases out of all KD patients whose serum concentration of whether platelet(PLT) or fibrinogen(FIB) was significantly increased or who were found thrombus in their coronary artery by ultrasonic Doppler were treated with LMWH by subcutaneous injection once every day for 7-10 days.All the patients were divided into 2 groups accor-ding to whether using LMWH or not:H group(using LMWH) and NH group(no using LMWH).It were detected before and after treatment that included thrombin time(TT),activated partial thromboplastin time(APTT),international normalized ratio(INR),FIB,plasma mucosity,erythrocyte sedimentation rate(ESR),hematocrit(HCT) and situation of haemorrhage.Results 1.Before treatment,PLT and FIB of patients in H group were significantly higher than those in NH group(Pa

Objective:To investigate the prognostic value of platelet volume indices (PVIs), neutrophil/lymphocyte ratio (NLR) and the combination of these parameters for the neurological function of acute ischemic stroke (AIS) patients after intravenous thrombolysis.Methods:From January 2016 to January 2019, the data of 147 AIS patients with intravenous thrombolysis in the Emergency Department of Peking University People's Hospital who met the diagnostic criteria of AIS were retrospectively analyzed. The patients were divided into two groups according to modified rank in scale (MRS) score: MRS≤2 and MRS≥3. The general information, past medical history and laboratory examination results of each group were compared. Logistic regression analysis was used to analyze the risk factors of poor prognosis of neurological function in AIS patients with thrombolysis.Results:NLR ( OR=1.045, 95% CI: 1.032-2.350, P=0.032), mean platelet volume (MPV) ( OR=4.212, 95% CI:1.074-16.513, P=0.039), MPV×NLR/PLT ( OR=5.711, 95% CI: 1.342-24.298, P=0.018), platelet distribution width (PDW) ( OR=1.015, 95% CI: 1.001-2.372, P=0.032), and NIHSS score ( OR=1.266, 95% CI: 1.111-1.443, P<0.01) were related with poor prognosis neurological function of AIS patients with intravenous thrombolysis. Conclusions:MPV, NLR, MPV×NLR/PLT PDW and NIHSS scores are the risk factors for poor prognosis of neurological function in AIS patients with thrombolysis. MPV×NLR/PLT can predict the neurological severity of AIS after 3 months.

Aim To study the effect of As_2O_3(arsenic trioxide) on the expressions of telomeric repeat binding factor1,2 and telomeric stability of human gastric cancer MGC803 cells, and explore the mechanism of cell apoptosis. Method MGC803 cell growth inhibition was measured with MTT assay. Apoptosis was analyzed with flow cytometry. Influence on chromosome distal end was analyzed with chromosome end-end fusion analysis. Expressions of TRF1 and TRF2 were determined with Western blot analysis. Results MTT assay showed that As_2O_3 clearly inhibited the growth of MGC803 cells, depending on time and dosage. The apoptosis rates were significantly higher than those of the control group in a concentration and time-dependent manner. These changes were not found in the control group. After disposal with 5 ?mol?L -1 As_2O_3, chromosome fusion rate was obviously increased in 48 h. After 48 h of disposal with 5 ?mol?L -1 As_2O_3, the TRF1 of MGC803 cells was up-regulated while TRF2 was down-regulated. Conclusion As_2O_3 induced chromosome fusion and MGC803 cells apoptosis through up-regulating expressin of TRF1 and down-regulating expressin of TRF2.

Objective To explore characteristics and significance of interferon-induced protein with tetratricopetide repeats 1 expressed in radiation injury and infection stress.Methods RNA was extracted from Raw264.7 cell,3T3 cell and 10T1 /2 cell after 5 hours stimulated with 5 μg/mL LPS.At the same time,to set up normal control group (untreated by LPS),and RNA of IFIT1 was detected by RT-PCR.Total-ly 20 C57 /BL6 mice were randomly divided into 4 groups,namely 0 h group,1 h group,4 h group and 12 h group.The mice were given 12 Gray60Co full-body exposure once,then liver IFIT1 was detected by western blot.Results Stimulated with LPS for 5 hours,IFIT1 was in-duced expression in Raw264.7 cell,3T3 cell and 10T1 /2 cell.The expression of normal control group was negative.The level of IFIT1 /Actin increased significantly 1 hour after radiation injury,and it reached the peak 12 hours after radiation injury (P <0.01).Conclusion LPS can stimulated a variety of cell lines expressed IFIT1,prompting that IFIT1 may participate in the occurrence and development of post-traumatic toxemia.IFIT1 of liver tissue increased significantly during the early stage in radiation mice.

Objective To investigate the effect of propofol on the cerebral injury induced by ketamine in neonatal rats. Methods Eighty 7-day-old SD rats of both sexes, weighing 12-20 g, were randomly divided into 4 groups (n = 20 each): normal saline (NS) group, ketamine-induced cerebral injury group (group K), propofol group (group P) and propofol combined with ketamine group (group PK). Group NS received intraperitoneal NS 1 ml. In groups K, P and PK, ketamine 70 mg/kg, propofol 70 mg/kg and propofol 70 mg/kg + ketamine 70 mg/kg were injected intraperitoneally once every 2 h for 3 times respectively. Ten rats in each group were selected and sacrificed at 24 h after emergence from anesthesia and the hippocampi obtained to determine the neuronal apoptosis (by TUNEL) and Bcl-2 and Bax protein expression(by immunohitochemistry). The apoptosis rate was calculated.The other 10 rats in each group were selected at 21 days after the intraperitoneal injection and the learning and memory functions (escape latency and frequency of crossing the original platform) were evaluated using Morris water maze. Results Compared with group NS, the apoptosis rate was significantly increased in group K, Bcl-2 protein expression was up-regulated in groups P and PK, and Bax protein expression was up-regulated, the escape latency was significantly prolonged and the frequency of crossing the original platform was significantly decreased in the other groups (P ＜ 0.05 .or 0.01 ). Compared with group K, the apoptosis rate was significantly decreased in group PK, Bax protein expression was down-regulated in group P, and Bcl-2 protein expression was up-regulated,the escape latency was significantly shortened and the frequency of crossing the original platform was significantlyincreased in groups P and PK ( P ＜ 0.05). Conclusion Propofol can reduce the cerebral injury induced by ketamine in neonatal rats, and the regulation of the Bcl-2 and Bax protein expression and inhibition of the neuronal apoptosis in hippocampus may be involved in the mechanism.

20?10~9/L. This regimen was given for one course for induction, and was followed by conventional chemotherapy as maintenance or consolidation when complete remission(CR) achieved, or succeeding with other treatment when no response could be observed. Results Six patients achieved CR (54.5%) and one achieved partial remission (PR)(9.1%) with one course of treatment. Among 6 of 11 patients with CR, 5 relapsed at 2,3,6,8 and 16 months respectively. Three relapsed patients were retreated with the same protocol but achieved only one partial responses. Nine of the 11 patients had been died and their mean survival (since induction chemotherapy) was 9.2 months. Infectious complications during cytopenia were less serious than conventional chemotherapy withno treatment-related.Conclusion This moderate intensity protocol with G-CSF priming is effective and safe but remissions are of short duration.
