Objective To investigate the accuracy of the GEM3000 arterial blood gas instrument when determine blood kalium,natrium,glucose of the results.Methods 80 cases were tested by the GEM3000 on the blood gas analysis,and simultaneously kalium and natrium of no anticoagulant blood alone(when the use of serum)and arterial blood remaining(when the use of plasma)were measured by the Bayer644 electrolyte analyzer,and measured glucose by the CX4 biochemical analyzer,carries on statistical processing to the result.Results The comparison of anticoagulant arterial blood plasma and anti-hemoglutination blood serum:a significant reduction in kalium tested by the GEM3000,natrium and glucose results showed non-significance difference.If we rectify the results by the GEM3000 properly,the error can be controlled in the permission variation scope.Conclusion As long as we take a blood sample and rectify the results of the arterial blood plasma of kalium tested by the GEM3000 which be introduced on this article,the impact of anticoagulant heparin on blood kalium,natrium,glucose measured by the GEM3000 can be reduced,and the results are reliable.

AIM: To investigate the mechanism of renal damage in chronic intermittent hypoxia (CIH) rat model.METHODS:The Sprague-Dawley rats were randomly divided into 2-week CIH group (2IH), 2-week simulated air control group (2C), 4-week CIH group (4IH) and 4-week simulated air control group (4C).HE staining, PAS staining and Masson staining were used for histological evaluation .Blood was collected for the measurement of superoxide dismutase (SOD).The mRNA expression of hypoxia-inducible factor-1α(HIF-1α), manganese superoxide dismutase (MnSOD), copper/zinc superoxide dismutase ( Cu/ZnSOD ) was detected by real-time PCR.RESULTS: ( 1 ) No significance difference of renal weight , body weight , and the ratio of renal weight to body weight was observed , while IH caused mor-phologic kidney damage , especially in 4IH group.Hypertrophy of epithelial cells in the kidney tubles and dilation in the glomeruli were observed under light microscope with HE and PAS staining , especially in 4IH group.Masson staining showed no significant fibrotic response in the kidney of the rats exposed to IH .(2) The SOD levels in the serum and kid-ney were decreased after CIH .Compared with the corresponding control groups , the levels of serum SOD were significantly lower in CIH groups, especially in 4IH group.The mRNA expression of Cu/ZnSOD and MnSOD in CIH groups decreased significantly as compared with control groups .The mRNA levels of HIF-1αwere significantly higher in CIH groups than those in the corresponding control groups .CONCLUSION: CIH induces abnormalities of glomeruli and convoluted tu-bules, while 4-week IH exposure has not led to fibrotic response .CIH participates in the process of renal oxidative stress damage by upregulating HIF-1αtranscription and downregulating Cu/ZnSOD and MnSOD transcription .

OBJECTIVETo observe the effects of acupoint catgut embedding assisting western medication and simple western medication on blood pressure and vascular endothelial function in patients with essential hypertension (EH), and to explore its mechanism.

METHODSA total of 125 cases were randomly assigned into an observation group (62 cases, 2 dropping) and a control group (63 cases, 3 dropping). Oral administration of lotensin (10 mg, once a day) was applied in the control group. Based on the treatment as the control group, acupoint catgut embedding was applied at Fengchi (GB 20), Ganshu (BL 18), Shenshu (BL 23), Quchi (LI 11), Zusanli (ST 36), Sanyinjiao (SP 6) and Taichong (LR 3) in the observation group, once every two weeks, and six treatments was taken as one session. All the patients were treated for 3 months. The blood pressure and the vascular endothelial injury markers, including endothelin-1 (ET-1), nitric oxide (NO), high sensitive C reactive protein (hsCRP) were recorded before and after treatment in the two groups. In addition, the ET-1, NO and hsCRP were collected from 60 cases of healthy participants.

RESULTSThe diastolic blood pressure and systolic blood pressure reduced after treatment in the two groups (all <0.05), which were more significant in the observation group (<0.01, <0.05). Before treatment, compared with those of the healthy participants, ET-1 and hsCRP were higher but NO was lower in the observation group and the control group (all <0.05); after treatment, ET-1 and hsCRP were reduced and NO increased in the two groups (all <0.05), which were more significant in the observation group (all <0.05). After treatment, the differences of NO and hsCRP between the observation group and healthy participants were not significant (both >0.05). The marked effective rate was 70.0% (42/60) in the observation group, which was superior to 33.3% (20/60) in the control group (<0.05); the total effective rate was 96.7% (58/60) in the observation group, which was superior to 85.0% (51/60) in the control group (<0.05).

CONCLUSIONThe vascular endothelial function is injured in EH patients. Based on lotensin treatment, acupoint catgut embedding could significantly improve blood pressure and vascular endothelial function.

Objective:To study the effects of early intervention on physical and neurological development of premature infants.Methods:One hundred and fifty-two premature infants born in Pan′an County Maternal and Child Health Family Planning Service Center from January 2017 to June 2018 were randomly selected. According to parents′ wishes, 75 cases received regular systematic health care and parenting guidance(control group), and 77 cases received targeted intervention guidance and individualized training on the basis of the control group(intervention group). The results of mental development index (MDI) and psychomotor Development index(PDI) were evaluated at 6 and 12 months respectively.Results:Six and 12 months after treatment, the MDI scores of the intervention group were significant higher than those of the control group [(94.2 ± 5.2) scores vs. (85.3 ± 6.1) scores, (104.9 ± 3.9) scores vs. (91.7 ± 5.7) scores], the PDI scores of the intervention group were also significant higher than those of control group [93.7 ± 4.3) scores vs. (81.7 ± 5.5) scores, (96.9 ± 3.8) scores vs. (83.9 ± 4.6) scores], and there were statistical differences ( P<0.05). Results:Early comprehensive intervention for premature infants has a good effect on their intelligence and motor ability development, which is worthy of clinical application.

OBJECTIVETo determine the clinical value of portable sleep testing by Watch-PAT (PAT) in children with obstructive sleep apnea syndrome (OSAS).

METHODFifty cases of snoring children aged 3-11 years were randomly selected to undergo the polysomnography (PSG) and PAT simultaneously at the same night. The consistency of sleep parameters in OSAS and non - OSAS children were compared with PSG as reference standard, and ROC curve analysis was performed to assess the sensitivity and specificity in the diagnosis of OSAS with PAT portable sleep monitor.

RESULTFourteen cases were diagnosed as OSAS in 6-11 years group by PAT and PSG. But in 3-5 years group, only six children were diagnosed as OSAS, there was significant difference between PAT and PSG (P < 0.05). Among those 6-11 years old children, compared with non-OSAS, PAT study showed that III+IV stage sleep ((30.5 ± 2.4)% vs. (38.2 ± 2.3)%, χ(2)=4.31, P<0.05), REM sleep duration ((8.9 ± 2.5)% vs. (18.3 ± 2.1)%, χ² =4.31, P<0.05), TST ((458 ± 78) min vs. (522 ± 56) min, t=4.85, P<0.05) and sleep efficiency ((83.5 ± 3.1)% vs. (93.5 ± 3.5)%, t=3.75, P<0.05) decreased, I+II stage sleep ((61.5 ± 4.4)% vs. (44.1 ± 3.5)%, χ² =6.07, P<0.05), arousal index ((29.5 ± 8.2)/h vs. (10.6 ± 5.6)/h, t=3.70, P<0.05), AHI ((7.6 ± 5.3)/h vs. (2.1 ± 2.0)/h, t=2.40, P<0.05), RDI((18.2 ± 5.1)/h vs. (6.5 ± 3.9)/h, t=3.85, P<0.05) increased in OSAS children. Furthermore, the total sleep time (TST) ((458 ± 78) min vs. (430 ± 76) min, t=2.90, P<0.05) and sleep efficiency ((83.5 ± 3.1) % vs. (81.9 ± 4.3) %, t=2.45, P<0.05) were higher by PAT than scored by PSG. ROC curve analysis showed the best threshold selection of AHI 5.0, the sensitivity was 0.952, the specificity was 0.858. AHI 7.0, the sensitivity was 0.968, the specificity was 0.985. AHI 10, the sensitivity was 0.985 and the specificity was 0.99, but AHI 1.0, the sensitivity was 0.852 and the specificity was 0.785.

CONCLUSIONPAT can be used at home in school age children due to the high consistency with PSG and the high compliance.
