Detection and Analysis of Routine Blood Indexes in Guike Pig

[Objectives] In this study,routine blood indexes of Guike pig were detected to clarify quantity variation and morphology distribution of different functional cells（ red blood cells,white blood cells and platelets）,thus providing reference data for immunological evaluation and disease resistance research of Guike pig. [Methods] Blood samples were collected from forty-four 49-day-old healthy Guike pigs（ 22 males and 22 females） once a week for seven consecutive weeks to detect routine blood indexes,and the results were compared with routine blood indexes of Landrace pig and Enshi black pig. [Results]Among red blood cell indexes of Guike pig at different day ages,red blood cell count（ RBC） and hemoglobin count（ HGB） both reached the lowest levels（ 6. 85 × 10^12/L and 97. 1 g/L）at 70 days of age,which were significantly lower than the corresponding indexes at 49,56,63,84 and 91 days of age（ P 〈 0. 05,similarly hereinafter）; mean corpuscular hemoglobin（ MCH） and mean corpuscular hemoglobin concentration（ MCHC） demonstrated basically the same variation pattern,which both reached the lowest levels（ 15. 11 pg and 275. 70 g/L） at 70 days of age and reached the highest levels（ 16. 40 pg and 314. 30 g/L） at 91 days of age; hematocrit（ HCT）,mean corpuscular volume（ MCV） and red blood cell distribution width（ RDW） exhibited relatively stable changes with no significant differences among different day ages（ P 〉 0. 05,similarly hereinafter）. Among white blood cell indexes of Guike pig at different day ages,white blood cell count（ WBC） reached the lowest level（ 13. 71 × 10^9/L） at 63 days of age and reached the highest level（ 17. 52 × 10^9/L） at 84 days of age,with significant differences; neutrophil count（ NEUT）reached the lowest level（ 3. 61 × 10^9/L） at 70 days of age,which was significantly lower than that at 49,56 and 77 days of age; lymphocyte count（ LYMPH） exhibited relatively stable changes and was not significantly affected by the increase in day age. Among platelet indexes of Guike pig at different day ages,platelet count（ PLT）,thrombocytocrit（ PCT） and platelet volume distribution width（ PDW） exhibited relatively stable changes among different day ages,which were not significantly affected by the increase in day age. Compared to 35-day-old Landrace pig and 5-month-old Enshi black pig,most routine blood indexes of Guike pig were similar to or ranged between those of Landrace pig and Enshi black pig except HCT,mean platelet volume（ MPV）,PCT and PDW. [Conclusions]Guike pig has a certain uniqueness in routine blood indexes,which has developed a stable immune system at 49-91 days of age.

Influence of Exercise at High Temperature on Blood Biochemical Indexes and HSP72 Expression in Adult Males

The influence of exercise at high temperature on adult males＇ routine blood indexes and biochemical indexes and the expression of HSP72 in peripheral blood lymphocytes （PBLs） was studied in order to provide theoretical ground for health supervision of adults receiving exercise at high temperature. 180 adult males were selected and divided into exercise group and control group, in which the exercise group was subdivided into subgroup 1 and subgroup 2 receiving exercise at high temperature in the afternoon and in the morning, respectively. Peripheral venous blood was phle- botomized before and after the exercise to examine routine blood indexes and blood biochemical indexes. The expression levels of HSP72 in PBLs were detected by flow cytometry. The results showed that the routine blood indexes and biochemical indexes in each group were within the range of normal values of male adults. There was no significant difference between each exercise group and control group in indexes before exercise. After exercise, the expression levels of HSP72 in PBLs in exercise groups were higher than those before exercise, and HSP72 expression levels in subgroup 1 were obviously higher than those in subgroup 2 and control group. The contents of ALT, urea, Na＋, Cl-, Ca2＋ and K＋ in subgroups 1 and 2 were lower than those in control group, but CK level was higher than in control group （P〈0.05）. The contents of Na＋ and Clin subgroup 1 were relatively lower than those in subgroup 2 （P〈0.05）. It was concluded that while receiving exercise at high temperature, adult males＇ HSP72 levels in PBLs could be increased and the biochemical indexes changed. Attention should be paid to health supervision to avoid obvious body injuries at high temperature.

Lung ultrasound score evaluation of the effect of pressure-controlled ventilation volume-guaranteed on patients undergoing laparoscopicassisted radical gastrectomy

BACKGROUND Laparoscopic-assisted radical gastrectomy(LARG)is the standard treatment for early-stage gastric carcinoma(GC).However,the negative impact of this proce-dure on respiratory function requires the optimized intraoperative management of patients in terms of ventilation.AIM To investigate the influence of pressure-controlled ventilation volume-guaranteed(PCV-VG)and volume-controlled ventilation(VCV)on blood gas analysis and pulmonary ventilation in patients undergoing LARG for GC based on the lung ultrasound score(LUS).METHODS The study included 103 patients with GC undergoing LARG from May 2020 to May 2023,with 52 cases undergoing PCV-VG(research group)and 51 cases undergoing VCV(control group).LUS were recorded at the time of entering the operating room(T0),20 minutes after anesthesia with endotracheal intubation(T1),30 minutes after artificial pneumoperitoneum(PP)establishment(T2),and 15 minutes after endotracheal tube removal(T5).For blood gas analysis,arterial partial pressure of oxygen(PaO_(2))and partial pressure of carbon dioxide(PaCO_(2))were observed.Peak airway pressure(P_(peak)),plateau pressure(Pplat),mean airway pressure(P_(mean)),and dynamic pulmonary compliance(C_(dyn))were recorded at T1 and T2,1 hour after PP establishment(T3),and at the end of the operation(T4).Postoperative pulmonary complications(PPCs)were recorded.Pre-and postoperative serum interleukin(IL)-1β,IL-6,and tumor necrosis factor-α(TNF-α)were measured by enzyme-linked immunosorbent assay.RESULTS Compared with those at T0,the whole,anterior,lateral,posterior,upper,lower,left,and right lung LUS of the research group were significantly reduced at T1,T2,and T5;in the control group,the LUS of the whole and partial lung regions(posterior,lower,and right lung)decreased significantly at T2,while at T5,the LUS of the whole and some regions(lateral,lower,and left lung)increased significantly.In comparison with the control group,the whole and regional LUS of the research group were reduced at T1,T2,and T5,with an increase in PaO_(2),decrease in PaCO_(2),reduction in P_(peak) at T1 to T4,increase in P_(mean) and C_(dyn),and decrease in Pplat at T4,all significant.The research group showed a significantly lower incidence of PPCs than the control group within 3 days postoperatively.Postoperative IL-1β,IL-6,and TNF-αsignificantly increased in both groups,with even higher levels in the control group.CONCLUSION LUS can indicate intraoperative non-uniformity and postural changes in pulmonary ventilation under PCV-VG and VCV.Under the lung protective ventilation strategy,the PCV-VG mode more significantly improved intraop-erative lung ventilation in patients undergoing LARG for GC and reduced lung injury-related cytokine production,thereby alleviating lung injury.

Birthing ball on promoting cervical ripening and its influence on the labor process and the neonatal blood gas index

BACKGROUND Term pregnancy-induced labor refers to the use of artificial methods to induce uterine contractions and terminate pregnancy after 37 wk.It is a common method to prevent overdue pregnancy and to deal with high-risk pregnancies.In addition,it can alleviate maternal complications and cause the fetus to leave the adverse intrauterine environment early,which is beneficial to the outcome of pregnancy.AIM To explore the effect of a birthing ball on labor by inducing cervical ripening and its influence on labor and the neonatal blood gas index.METHODS Twenty-two women who were scheduled to undergo labor induction and delivery in the obstetrics department of our hospital were randomly divided into two groups:the delivery ball group(childbirth ball combined with COOK balloon induction)and the conventional group(COOK balloon induction alone).The cervical Bishop score before and after intervention,duration of labor at each stage,mode of delivery,neonatal umbilical venous blood pH,oxygen partial pressure(PO_(2)),carbon dioxide partial pressure(PCO_(2)),and the 1-min Apgar score were recorded.RESULTS After the intervention,the cervical Bishop score of the delivery ball group(7.84±1.52)was significantly higher than that of the conventional group(7.32±1.29)(P<0.05),and the cervical Bishop scores of the two groups after intervention were significantly higher than those before intervention(P<0.05).After the intervention,the first stage of labor(510.9±98.7 min),the second stage of labor(43.0±8.5 min),and the total duration of labor(560.0±120.9 min)in the delivery ball group were lower than those in the routine group,with a first stage of labor of 602.1±133.2 min,a second stage of labor of 48.4±9.1 min,and a total duration of labor of 656.8±148.5 min(P<0.05).There was no significant difference in the time of the third stage of labor between the two groups(P>0.05).There was no significant difference in the pH,PO_(2),and PCO_(2) values of newborns between the delivery ball group and the conventional group(P>0.05).The 1-min Apgar score of the delivery ball group was higher than that of the conventional group(9.10±0.38 points vs 8.94±0.31 points,P<0.05).The natural delivery rate of the delivery ball group was higher than that of the conventional group(91.00%vs 78.00%,P<0.05).CONCLUSION The use of a birthing ball combined with a COOK balloon for inducing labor has a better effect on promoting cervical ripening,shortening the time of labor,and improving the Apgar score of newborns.

Prevalence and Correlates of Elevated Blood Pressure in Chinese Children Aged 6-13 Years: a Nationwide School-Based Survey

Objective To estimate the prevalence of elevated blood pressure（EBP） in Chinese children and identify individual and family factors associated with EBP. Methods A nationwide cross-sectional study was conducted in 2010 using stratified cluster sampling. Participants＇ blood pressure was measured, and their parents completed a questionnaire on personal and family characteristics. Prevalence and correlates of EBP were assessed. Results Among a total of 24,333 participants, 20.2% of boys and 16.3% of girls had EBP. The prevalence of EBP increased with the ascending trend of waist circumference, Waist-to-height ratio, and body mass index. The adjusted prevalence ratios（aP Rs） for obese boys and girls were 2.50 and 2.97, respectively. Fewer urban boys（16.2%） had EBP than rural boys（21.7%）. Boys with a family history of hypertension were 12% more likely to have EBP. Children whose mothers received a college education tended to have lower likelihood of EBP; with an aP R was 0.85 among boys and 0.78 among girls. Conclusion EBP is common among obese students and those who have a family history of hypertension. A negative association between mothers＇ education levels and EBP risk in children was found.

Laboratory scoring system to predict hepatic indocyanine green clearance ability during fluorescence imaging-guided laparoscopic hepatectomy

BACKGROUND Indocyanine green(ICG)fluorescence played an important role in tumor localization and margin delineation in hepatobiliary surgery.However,the preoperative regimen of ICG administration was still controversial.Factors associated with tumor fluorescence staining effect were unclear.AIM To investigate the preoperative laboratory indexes corelated with ICG fluorescence staining effect and establish a novel laboratory scoring system to screen specifical patients who need ICG dose adjustment.METHODS To investigate the predictive indicators of ICG fluorescence characteristics in patients undergoing laparoscopic hepatectomy from January 2018 to January 2021 were included.Blood laboratory tests were completed within 1 wk before surgery.All patients received 5 mg ICG injection 24 h before surgery for preliminary tumor imaging.ImageJ software was used to measure the fluorescence intensity values of regions of interest.Correlation analysis was used to identify risk factors.A laboratory risk model was established to identify individuals at high risk for high liver background fluorescence.RESULTS There were 110 patients who were enrolled in this study from January 2019 to January 2021.The mean values of fluorescence intensity of liver background(FI-LB),fluorescence intensity of gallbladder,and fluorescence intensity of target area were 18.87±17.06,54.84±33.29,and 68.56±36.11,respectively.The receiver operating characteristic(ROC)curve showed that FI-LB was a good indicator for liver clearance ability[area under the ROC curve(AUC)=0.984].Correlation analysis found pre-operative aspartate aminotransferase,alanine aminotransferase,gammaglutamyl transpeptidase,adenosine deaminase,and lactate dehydrogenase were positively associated with FI-LB and red blood cell,cholinesterase,and were negatively associated with FI-LB.Total laboratory risk score(TLRS)was calculated according to ROC curve(AUC=0.848,sensitivity=0.773,specificity=0.885).When TLRS was greater than 6.5,the liver clearance ability of ICG was considered as poor.CONCLUSION Preoperative laboratory blood indicators can predict hepatic ICG clearance ability.Surgeons can adjust the dose and timing of ICG preoperatively to achieve better liver fluorescent staining.

Live yeast supplementation during late gestation and lactation affects reproductive performance,colostrum and milk composition,blood biochemical and immunological parameters of sows

This study was conducted to evaluate the effects of dietary live yeast(LY)supplementation during late gestation and lactation on reproductive performance,colostrum and milk composition,blood biochemical and immunological parameters of sows.A total of 40 multiparous sows were randomly fed either the control(CON)diet or the CON diet supplemented with LY at 1 g/kg from d 90 of gestation to weaning.Results showed that the number of stillborn piglets and low BW piglets were significantly decreased in the LY-supplemented sows compared with sows in the CON group(P<0.05).Moreover,the concentrations of protein,lactose and solids-not-fat were increased in the colostrum of LY-supplemented sows(P<0.05).Interestingly,the plasma activities of aspartate aminotransferase(AST),alkaline phosphatase(ALP),gamma-glutamyl transpeptidase(γ-GGT)at d 1 of lactation and alanine aminotransferase(ALT)at weaning day were decreased by feeding LY diet(P<0.05).Meanwhile,sows fed LY diet had higher plasma concentration of immunoglobulin G compared with sows fed CON diet at d 1 of lactation(P<0.05),In conclusion,LY supplementation in maternal diets decreased the number of stillborn piglets and low BW piglets,improved colostrum quality and health status of sows.
