1.The effect of intrauterine growth restriction on the development of brain function in premature infants
Journal of Clinical Pediatrics 2017;35(7):525-528,536
Objective To explore the effect of intrauterine growth restriction (IUGR) on the development of brain function in premature infants. Methods A total of 110 premature infants of gestation age of 32-36 weeks were monitored by NicoletOne neonatal cerebral function monitor within 72 hours after birth during January 2015 to February 2016. There were 50 small for gestational age infants (SGA) and 60 appropriate for gestational age infants (AGA). They were continuously monitored for 4-6 hours every time, and the indices of aEEG continuity, sleep wake cycle (SWC), inter-burst interval (IBI), minimum and maximum voltage were compared between two groups. Results The frequency of aEEG continuity, the rate of SWC, and the maximum and minimum voltage in SGA group were all lower than those in AGA group, while the IBI was longer than that in AGA group, and there were significant differences (P<0.05). The frequency of aEEG continuity, the rate of SWC, IBI, and the minimum and maximum voltage were similar (all P> 0.05) among birth weight

Objective To study the inhibitory effects of gene combined radiotherapy on mice transplanted with B16 melanoma.Methods Alkaline lysis assay was used to extract and purify the plasmid.Plasmid DNA was injected into tumor by microinjection assay.Mice were inoculated with 5?10~5 of B16 melanoma in right hind legs and the therapy was performed when the diameter of tumor reached at 0.30.5 cm.pNE-mIL-12 and pcDNA-B7-1 plasmids were injected locally three times following with irradiation three times.The tumor growth rate of mice was observed.Results The anti-tumor effect of pNE-mIL-12 combined with pcDNA-B7-1 plasmid following with 2 Gy X-ray irradiation was much better than other groups.It showed that the tumor growth rate was slowed,the survival days of mice were delayed significantly(P

Objective: To discuss the purposes and methods of determining and employing operational intervention levels in preparedness and response for a nuclear emergency. Methods:According to the safety standards and technical reports issued by the International Atomic Energy Agency (IAEA) and combined with specific conditions in China, the operational intervention levels suitable for applying in China are analyzed. Results: The newly published IAEA technical report provided special operational intervention levels for emergency at a light water reactor. The recommended values are practical that our country can use for reference. Conclusion: It is suggested that the related branches for response to nuclear emergency in China establish feasible operational intervention levels by referring to the IAEA reports and taking into account the special conditions of nuclear facilities in China, in order to improve the capability of medical response to nuclear emergency.

Objective Assess the value of several biomarkers and disease severity scores for the prognostic assessment of sepsis.Methods The clinical data of adult patients, who met the diagnostic criteria for Sepsis-3 and admitted to the intensive care unit (ICU) of Affiliated Hospital of Guizhou Medical University from January 2015 to December 2016 were retrospectively analyzed. These patients were divided into survival group and death group. The levels of serum lactate (Lac), lactate clearance rate of 24 hours later (24 h LCR), procalcitonin (PCT), quick sequential organ failure assessment (qSOFA) score, SOFA score, simplified acute physiology score Ⅱ (SAPS Ⅱ), acute physiology and chronic health evaluation scoring system Ⅱ (APACHE Ⅱ) score were determined, and the receiver operating characteristic curve (ROC) were used to analyze the prognostic value of the indicators above.Results 110 of 152 sepsis patients survived, while the others died. Compared with survival group, serum Lac, PCT, SOFA score, qSOFA score, SAPS Ⅱ score, APACHE Ⅱ score of death group were increased, and 24 h LCR was decreased. SAPS Ⅱ[area under the ROC curve (AUC) = 0.877,P = 0.000, when threshold value was 41.50, sensitivity was 94.3%, specificity was 68.5%], 24 h LCR (AUC = 0.869,P = 0.000, when threshold value was 40.2%, sensitivity was 92.1%, specificity was 75.5%) and SOFA score (AUC = 0.815,P = 0.000, when threshold value was 7.60, sensitivity was 79.9%, specificity was 78.5%) showed better predictive value of sepsis. However, the predictive value of PCT (AUC = 0.759), Lac (AUC = 0.725), qSOFA (AUC = 0.701) and APACHE Ⅱ score (AUC = 0.680) were poorer (AUC = 0.6-0.8). For sepsis caused by abdominal cavity infection, the most accurate index was SOFA score (AUC = 0.889,P = 0.000, when threshold value was 9.50, sensitivity was 81.2%, specificity was 83.5%), and for sepsis caused by pneumonia, the most accurate index was PCT (AUC = 0.891,P = 0.001, when threshold value was 3.95 mg/L, sensitivity was 84.7%, specificity was 94.1%).Conclusion SOFA score and qSOFA score cannot take the place of traditional evaluation index for the evaluation of the prognosis of patients with sepsis.

Methods Gentianae Radix et Rhizoma, Bupleuri Radix, Scutellariae Radix, Gardeniae Fructus, Alismatis Rhizoma, Angelicae Sinensis Radix, Rehmanniae Radix and Glycyrrhizae Radix et Rhizoma were identified by TLC. Gentiopicrin in Gentianae Radix et Rhizoma, geniposide in Gardeniae Fructus, baicalin in Scutellariae Radix were determined by HPLC. Results The TLC spots developed were clear. Gentiopicrin showed good linear relationship in the range of 0.066 1-0.595 1 mg (r=1.000 0), the average recovery of Capsule was 99.34%(RSD=1.50%), and the average recovery of Soft Capsule was 96.62%(RSD=1.50%). Geniposide showed good linear relationship in the range of 0.076 1-1.369 8 mg (r=0.999 9), the average recovery of Capsule was 101.3% (RSD=1.70%), and the average recovery of Soft Capsule was 100.59%(RSD=0.79%). Baicalin showed good linear relationship in the range of 0.214 4-1.608 mg (r=1.000 0), the average recovery of Capsule was 101.12% (RSD=1.30%), and the average recovery of Soft Capsule was 98.07% (RSD=2.40%).

Objective:Our purpose was to investigate the growth regulation and postreceptor signal transduction of somatostatin (SS) on human colon cancer cell line. Methods:Low differentiated clone A cells of human carcinoma were treated with different concentrations of SS and the growth status was observed. Intracellular 1,4,5-trisphosphate (IP3) and cyclic adenosine monophosphate (cAMP) were extracted, then the concentrations of them were measured by liquid scintillation technique and gamma scintillation counter.Intracellular free calcium concentration was detected by loading Fura-2 and fluorescental technique. Protein kinase C (PKC) was extracted from cytosol and membrane, then the activity of both parts was determined with TaKai method. Results:The clone A cell growth was inhibited greatly by different concentrations of SS (10-10 to 10-5 mol/L) and it is related to the doses of SS.Somatortatin could largely inhibit the production of intracellular IP3, [Ca2+]i, and cAMP, and decrease the activity of PKC. Conclusion:The growth of Clone A cell can be inhibited by SS. The inhibition may be mediated by phosphate inositol pathway, so intracellular IP3, [Ca2+]i decreased, or inhibited the cell growth by inhibiting the activity of PKC.On the other hand, the cell proliferation may be inhibited by adenosine cyclase pathway, that is decreasing intracellular cAMP ,inhibiting cAMP-depending protein kinase.

Objective To discuss the diagnosis and treatment of acquired cystic kidney disease complicated by kidney cancer. Methods Clinical data of 11 patients with acquired cystic kidney disease complicated by kidney cancer were analyzed retrospectively. Eight patients were male and three were female. The mean age was 55 years old (range 37 to 68). The time of hemodialysis ranged from 2.8 to 7. 4 years, mean 4. 8 years. Results Follow-up ranged from 17- 83 months, mean 55 months. One patient died of cardiovascular disease. Lung metastasis was detected in one patient two years after surgery. Seven patients survived free of tumor recurrence and there was no follow-up on one patient. Conclusions Increased incidence of cancer was observed in patients with end-stage renal disease who have undergone long-term dialysis. In particular, renal cell carcinoma (RCC) showed an excess incidence in ACKD patients. RCC showed an increased prevalence compared with the general population. Patients with predialysis azotemia or a dialysis duration of longer than 3 years should be screened for ACKD. Sonegraphy or CT scanning are useful for early diagnosis of ACKD. We should pay close attention to complications, including ACKD malignant tendency, in patients who have been taking long-term dialysis and positive therapy.
