Background and purpose:Stanniocalcin 1 (STC1) has been reported to be up-regulated in various cancer tissues, and related to malignancy degree of cancer. However, the molecular mechanism of STC1 in lung cancer cells is still not clear. This experiment aimed to investigate the effects of STC1 on cell cycle and apoptosis of lung cancer A549 cells.Methods:A549 cells were transfected with validated siRNA for STC1 A549-STC1-siRNA and a negative control vector RNA A549-Vector. The gene and protein expression of cell cycle-related genes, including CyclinA, CyclinB1, CyclinD1, CyclinE, CDK2 and CDK4, as well as apoptosis-inhibiting genes Bcl-2, Bcl-xl and apoptosis-inducing genes Caspase-3, Bax, Bak and Bid, were detected by real-time lfuorescent quantitative polymerase chain reaction (RTFQ-PCR) and Western blot. The cell cycle distribution was determined with lfow cytometry. Terminal deoxynucleotidyl transferase-mediated nick-end labeling (TUNEL) was used to detect cell apoptosis.Results:After transfection with STC1-siRNA, the gene and protein expression of CyclinA, CyclinB1, CyclinD1, CyclinE, CDK2 and CDK4 decreased signiifcantly in A549 cells (P<0.05). The proportion of cells in G0/G1 phase signiifcantly increased,
whereas the proportion of cells in S phase and G2/M phase decreased (P<0.05). The cell cycle was blocked at G0/G1 phase. Furthermore, compared with that in A549-Vector, the gene and protein expression of Bcl-2 and Bcl-xl in A549-STC1-siRNA was reduced signiifcantly (P<0.05), while the expression of apoptosis-inducing genes Caspase-3, Bax, Bak and Bid increased obviously (P<0.05). In addition, the percentage of apoptotic cells significantly increased in A549-STC1-siRNA compared with that in A549-Vector detected by TUNEL method.Conclusion:Down-regulation of STC1 by RNAi can block the cell cycle of A549 cells, inhibit cell proliferation, and promote cell apoptosis.

Objective To investigate the efficacy of volume target pressure control(VTPC)and synchronized intermittent mandatory ventilation(SIMV)in treating severe neonatal respiratory distress syndrome(NRDS). Methods Fifty - six admitted cases with severe NRDS hospitalized in Jiangmen Central Hospital from October 2012 to March 2015 were randomly divided into 2 groups:28 cases in VTPC group were treated by VTPC and SIMV,and 28 cases in pressure control ventilation(PCV)group were treated by PCV and SIMV. There was no significant difference between 2 groups in terms of gender,gestational age,and birth weight(all P ﹥ 0. 05). Artery blood gas analysis was performed at 6 hours,12 hours,24 hours,and 48 hours respectively after ventilation. The following parameters were observed:the time of invasive mechanical ventilation,duration of oxygen therapy,mortality and the incidence rates of hypocapnia,pneumo-thorax,ventilator associated pneumonia( VAP),grade Ⅲ - Ⅳ periventricular intraventricular hemorrhage( PVH -IVH),periventricular leukomalacia(PVL)and bronchopulmonary dysplasia(BPD). Results No case in 2 groups withdrew from the test. There was no significant difference between 2 groups in terms of the first treatment time and total doses of poractant alfa injection(all P ﹥ 0. 05). The time of invasive mechanical ventilation in VTPC group[(71. 75 ± 9. 82)h]was shorter than that in PVC group[(97. 89 ± 16. 88)h](t = 7. 083,P = 0. 000). Hypocapnia incidence of four blood gas analysis in VTPC group[(19. 64 ± 14. 20)% ]was lower than that in PCV group[(47. 32 ± 18. 43)% ] (t = 6. 294,P = 0. 000). Incidence rates of VAP and PVL in VTPC group were lower than those in PCV group(χ2 =5. 197,P = 0. 023;χ2 = 4. 766,P = 0. 029). However,duration of oxygen therapy,mortality and the incidence rates of pneumothorax,Ⅲ - Ⅳ PVH - IVH and BPD were not significantly different between 2 groups( all P ﹥ 0. 05). Conclusion VTPC + SIMV has a better efficacy than PCV + SIMV in the treatment of NRDS.

Objective To investigate the gene sequence and mutations of human papillomavirus(HPV)type16E6E7in patients with HPV infection in Beijing.Methods Sample DNA was extracted from lesions in patients with HPV infection.HPV types were identified by polymerase chain reaction(PCR).E6E7gene,isolated from samples infected with HPV16only,was cloned into plasmid pGEM-3zf and sequenced.Results The recombinant plasmid pGEM/16E6E7was constructed successfully.The whole HPV E6E7gene was776bp in length which was equal to that of the standard strain.Three nucleotides exchanges,i.e.,p60PROE6,p96GLUE6,p565SERE7,were found in E6E7gene.Conclusion The data suggest that there are nucleotide differences of HPV E6E7gene between HPV obtained from Beijing and that of standard sequence.

objective To analyze the clinicopathological features and prognosis of antiglomerular basement membrane(GBM)disease,and evaluate the efficacy and safety of double filtration plasmapheresis(DFPP). Methods A total of 35 hospitalized patients diagnosed as anti-GBM disease in our department were enrolled in the study.All the patients were divided into 3 groups according to the manifestations at admission.Group Ⅰ∶24 patients with severe pulmonary hemorrhage or rapidly progressive glomerulonephritis(RPGN)received pulse methylprednisolone with or without DFPP,and then followed by prednisone and CTX.Group Ⅱ∶5 patients without severe pulmonary hemorrhage and RPGN received prednisone and CTX.Group Ⅲ∶5 ESRD patients and 1 normal renal function patient did not receive immunosuppression therapy.Anti-GBM antibody titer of pre-and post-DFPP in 4 patients was measured consecutively,and removal rate was calculated.Results The mean age of all the patients was(41.1±16.6)years.Sixteen patients(45.7%)presented Goodpasture's syndrome.Eighteen patients(51.4%)had anti-GBM glomerulonephritis alone,whereas one suffered solely from pulmonary hemorrhage.20%patients had positive P-ANCA serology.54.2%crescentic glomerulonephritis and 7 with other glomerulonephritis were revealed by kidney biopsy in 24 patients.Patients in Group Ⅰ showed more severe manifestation at admission:higher Scr level,higher titer of anit-GBM antibody,greater percentage of crescents.Within the follow-up period,7 patients died and kidneys of 50%patients survived.No patient died in Group Ⅱ and Ⅲ.The elder age,anemia,higher Scr(＞300 μmol/L),oliguria or anuria,emergency hemodialysis at admission,and more glomerular sclerosis were predictors of poor prognosis.The anti-GBM antibody was negative after 4 to 6 sessions of DFPP.and the mean removal rate was 55%.During total 94 DFPP sessions,there was no unacceptable morbidity. Conclusions Different therapy strategy is necessary for anti-GBM disease with different clinical manifestations.DFPP is an effective and safe clearance way of anti-GBM antibody.

Objective By analysis of the key performance indexes of the clinical laboratory automation system, to clarify the advantage and optimize the comprehensive performance of the laboratory automation system.Methods Key performance indexes were Collected from January 2017 to April 2017 in biochemistry and immunoassay group of Clinical Laboratory of Shanghai Tong Ren Hospital.(1)The data were collected and compared by the before-and-after method,the starting time of the automation system and initial sample test were analyzed.(2)Key performance indexes were analyzed for the time of specimen registration,inspection,and reporting.(3)The specimen turnaround time(TAT)was analyzed based on two months operation of the laboratory automation system.In view of disadvantage of infectious assays, setting up priority sample absorption, then TAT performance was re-evaluated.(4)By the assessment of total serum dosage required in the automation system, the number of blood vacuum tubes were reduced reasonably.The pros and cons of laboratory automation system were analyzed and the potential improvement were proposed.Results (1)According to the sample peak shift forward,the system start time could move forward 30 minutes earlier.(2)With the adopting of railway logistics,the specimens were sent to the lab and the registration time was at 7:25 am,and the time required for specimen delivery was greatly reduced which made specimen test,report and audit time all moved forward accordingly.(3)Data has shown that specimen TAT declined dramatically based on the performance of the first two month operation of the automation system,biochemical items were shortened 2 h,and the immunoassay shortened 4 h,respectively.Moreover the trend keeps better gradually.With setting up priority absorption infectious tests,the TAT was improved greatly,TAT reduced the average by 40 min.(4)500 μl(including the sample in dead space of vacuum tube)were needed for all the 65 biochemical items included in the system, and 1 495 μl serum were used for the 28 immunoassay.As a result, a total of 2 000 μl serum will be enough for sample analysis by the system, which provided the feasibility to reduce 3 vacuum tubes averagely.Considering the current automation system does not include all the analysis items in our lab directory, a few tests remain to be performed on offline instruments respectively.The methodology for some infectious agents are different from previous method, therefore some test results may need a period of time for comprehensive clinical appreciation.Furthermore,due to the parallel connection of multiple instruments included in the system, more rigorous and frequent quality control becomes a necessity,which may rely on more strict quality control procedure to guarantee the quality.Conclusions The application of the automation system significantly enhanced the efficiency of clinical laboratory all round.In addition, by the quantitative indicators, it is possible to monitor the system operation performance real time, which may feedback and facilitate the improvement constantly,and result in auto confirmation the majority results,eventually.

Objective: To explore the characteristics of thrombelastogaphy (TEG) in term neonates, and to evaluate their correlation with traditional coagulation tests. Methods: A total of 52 term neonates were enrolled as neonatal group and 34 adults undergoing elective surgery as adult control group in Jiangmen Central Hospital from January to December 2017.TEG, plasma coagulation test and platelet counts (PLT) were performed and the corresponding ana-lysis was conducted. Results: TEG parameters in term neonates: response time(R)(4.18±1.08)min, clot kinetics(K)(1.21±0.45) min, α angle (Angle)(73.08±5.74)°, maximum amplitude(MA)(65.68±7.13)mm.Compared with adult control group, neonatal group exhibited shorter R and K(t=3.764, P<0.001; t=4.888, P<0.001), higher Angle, MA(t=5.539, P<0.001; t=2.873, P=0.001). In traditional coagulation, compared with adult control group, neonatal group showed longer prothrombin time(PT), activated partial thromboplastin time(APTT), thrombin time(TT) (t=5.449, P<0.001; t=13.134, P<0.001; t=3.575, P=0.001), lower fibrinogen(Fib) (t=4.164, P<0.001), and higher PLT (t=4.230, P<0.001). In addition, K was negatively correlated with Fib(r=-0.374, P=0.004), while Angle and MA were positively correlated with Fib(r=0.354, P=0.007; r=0.630, P<0.001); K was negatively correlated with PLT(r=-0.430, P=0.001), but Angle and MA were positively correlated with PLT (r=0.427, P=0.001; r=0.586, P<0.001); K was positively correlated with APTT(r=0.285, P=0.035), and MA was negatively correlated with APTT(r=-0.324, P=0.017). There was no significant correlation between R and traditional coagulation test.K, MA and Angle were not significantly correlated with PT (all P>0.05), and Angle and APTT were not significantly correlated (all P>0.05). Conclusions The reference interval of TEG in term neonates is different from adults.And the parameters of TEG in term neonates are partly related to the traditional coagulation tests.
