Objective To observe the effects of 6%hydroxyethyl starch(Volven 130/0.4)infusion on hemodynamics and coagulation.Methods 60 cases of open heart surgical children under cardiopulmonary bypass were randomly divided into two groups(30 cases for each):The control group(group C)were infused with 400 ml plasma and volven group(group V)were infused with 400 ml Volven before cardiopulmonary bypass.Then mean aterial pressrue(MAP),heart rate(HR),and central venous pressure(CVP)were measured.The venous blood samples were collected before and after infusion for the measurements of the following parameters:haematocrit(HCT),blood sedimentation(BSR),platelet count(PLC),prothrombin time(PT),and activated whole blood clot time(ACT).Those indexes before operation,15 min after bypass,after returning to ICU,and 24 hours after operation were observed.Results HCT and PLC after infusion were significantly lower than that before infusion.BSR after infusion was significantly faster than that before infusion.There were no significant changes in MAP,HR,CVP,PLC,ACT and PT.Conclusion 6%Hydroxyethyl starch infusion is safe and beneficial during cardiopulmonary bypass.

Objective To illustrate the composition ratio of ERβ isoforms in paired cancerous and adjacent normal tissues from breast cancer patients.Methods Eighty-seven pairs of cancerous and adjacent normal tissues were obtained from breast cancer patients.RT-qPCR was used to determine the relative mRNA expression levels of ERβ isoforms (ER[β1,ERβ2 and ERβ5),and the composition ratios of ERβ isoforms were analyzed.Results The expression levels of all tested ERβ isoforms (ERβ1,ERβ2 and ERβ5) in breast cancer tissues were much lower than those in adjacent normal breast tissues (P ＜ 0.01).Isoform ratio analysis showed that ERβ5 was the dominant isoform in both cancerous and adjacent normal tissues with a positive detection rate of 54.02 ％ and 75.84 ％,respectively.Meanwhile,ERβ1 had the lowest detection rate (9.74 ％ and 6.77 ％ in cancerous and adjacent normal tissues,respectively).The positive rates for both ERβ1 and ERβ2 were much lower in adjacent normal tissues than those in cancer tissues (Z =-2.24,P =0.025 and Z =-4.85,P ＜ 0.01,separately),while more cancerous tissues were ERβ5-positive in comparison to adjacent normal tissues (Z =-5.32,P ＜ 0.01).Conclusions The expression levels of all the ERβ isoforms are differentially down-regulated with significant alterations in their composition ratios during breast carcinogenesis.Further understanding on molecular mechanisms underlying the differential down-regulation of ER[β isoforms will shed new light on breast carcinogenesis.

Objective To explore the clinical significance and the dynamic changes of serum anti-inflam-mation factor interleukin-10(IL-10)and inflammatory factor interleukin-8(IL-8)in cerebral infarction.Methods The serum levels of IL-10 and IL-8 in 30 patients were measured by double-antibody sandwich enzyme-linked inunu-nosorbent assay(ELISA)on days 1.3,7 and 14 respectively after infarction.Results The serum levels of IL-10 and IL-8 were higher in patients than those in control group on days 1,3 and 7(P<0.05).Conclusion IL-10 and IL-8 are involved in the pathophysiology of acute cerebral infarction.

Objective To explore the value of sonohysterography (SHG) in diagnosis of post-cesarean scar diverticulum.Methods Totally 28 patients with post-cesarean scar diverticulum suspected clinical underwent SHG and conventional transvaginal ultrasound (TVS).The sizes of the diverticulum and the thickness of muscular layer were observed and the diagnostic value of SHG and TVS were compared.All patients underwent hysteroscopy,and the results were considered as diagnostic standard.Results Twenty diverticulums were found by hysteroscopy,20 diverticulums by SHG and 17 diverticulums by TVS.Taking hysteroscopy as diagnostic standard,the accuracy of SHG,TVS in diagnosis of diverticulums were 100％ (20/20) and 89.29％ (17/20) respectively.Superoinferior diameter ([9.17 ± 2.63] mm),left-right diameter ([11.76± 5.67]mm) of diverticulum and thickness of muscular layer ([3.29 ± 1.01]mm) measured by TVS had statistical differences compared with those measured by SHG (superoinferior diameter:[12.01± 4.04]mm,left-right diameter:[12.37±6.14]mm,thickness:[2.85±1.30]mm,all P＜0.05).The altitude of diverticulum measured by TVS and SHG had no statistial difference ([5.62±± 2.13]mm vs [5.50±2.34]mm,P＞0.05).Five patients with intra uterine adhesions,4 with endometrial polyps and 1 with submucosal myoma were detected by SHG.Conclusion SHG has clinical value in di agnosis of post-cesarean scar diverticulum..

Mental retardation is defined by significant limitations in intellectual function and adaptive behavior that occur before 18 years of age. Many chromosomal diseases come with mental retardation. We reported two Chinese families with partial trisomy 9p and other chromosome partial monosomy, clinical features of mental retardation and mild facial and pinkie anomalies. In the family 1, we showed that the proband carried a trisomy 9p21.3→pter and monosomy 21q22.3→qter by using fluorescence in situ hybridization analysis. Molecular genetic analysis defined the precise breakpoint on chromosome 9p between markers D9S1846 and D9S171, an interval of about 2.9 Mb on 9p21.3, and the breakpoint on chromosome 21q between markers D21S1897 and D21S1446, a region of about 1.5 Mb on 21q22.3. In the family 2, a patient with trisomy 9p21.3→pter and monosomy 5p15.33→pter, and a de novo maternal balanced translocation between chromosomes 5 and 9 was identified in his mother. Cytogenetic and molecular genetic analysis defined the precise breakpoints on chromosome 9p21.3 and chromosome 5p15.33. Further clinical investigation found that any individual had no refractoriness eczema disease except the proband in this family. These results further implicate that trisomy 9p is associated with mental retardation, and that there may be key gene duplication on chromosome 9p21.3→9pter responsible for mental retardation and mild facial anomaly. This result has been applied successfully in prenatal diagnosis of the second family.

OBJECTIVE: To investigate the clinical feature and diagnostic criteria of Kartagener syndrome, and related treatment of sinusitis and nasal polyps. METHOD: The clinical data of 5 patients which were diagnosed as complete Kartagener syndrome in The forth hospital of Hebei medical university were analyzed retrospectively. The first symptom of these patients was sinusitis. All of them accepted cardiac apical auscultation, X ray of orthophoria chest film and chest CT plain scan examination before diagnosis. All of them were treated intervention therapy in outpatient department,and 1 case accepted endoscopic sinus surgery in the hospital. The analysis of the data was to investigate the diagnosis in outpatient department and the perioperative therapy effect. RESULT: All of the 5 patients' clinical feature were total mirror situs inversus viscerum, Dexcrocardia and brochiectasis associated with infection, "signet ring sign", "tram line sign", "honeycomb sign" at different degree on chest CT, bilateral maxillary and ethmoidal sinus inflammation on sinus CT. All the 5 patients appeared bilateral secretor otitis media associated with conductive deafness at different degree. 4 cases accepted anti-inflammation,mucus diluted and medicine treatment to improve cilia activity. 1 case accepted medicine and endoscopic sinus operation for obvious nasal symptoms. After following up for years,all symptoms of the 5 patients relieved, so did recurrent bronchiectasis infection. 1 case with operation had obviously relieved symptom and no postoperative complication. CONCLUSION Although complete Kartagener syndrome is infrequent disease, heart auscultation diagnosis and image examination are effective method to reduce missed diagnosis. Symptomatic treatment and suitable endoscopic sinus surgery method can reduce sinus symptom and the infection possibility of bronchiectasis effectively,which is beneficial for KS outcome.

Objective:To investigate the normal parameter values of transvaginal E-Cervix cervical elastography of primipara and explore the correlation between E-Cervix parameters and gestational age.Methods:A total of 301 primiparas underwent E-Cervix by transvaginal ultrasound in Henan Provincial People′s Hospital from March 2019 to January 2021, they were divided into 6 groups according to generational weeks: group A (11-13 + 6W), group B (14-17 + 6W), group C (18-21 + 6W), group D (22-25 + 6W), group E (26-29 + 6W), group F (30-33 + 6W). Real-time E-Cervix parameters were obtained, including elasticity contrast index (ECI), hardness ratio (HR), internal ostium (IOS), and external ostium (EOS), strain ratio of the internal and external cervical ostium (IOS/EOS), and the correlations between E-Cervix parameters and the gestational week were analyzed. Results:The normal reference ranges of parameters ECI, IOS, EOS, HR and IOS/EOS were obtained, their 95% reference values in groups A to F were as follows: ECI (1.84-3.38, 2.13-4.50, 2.25-4.12, 2.06-3.96, 2.04-5.15, 2.36-5.53), HR (85.85%-88.72%, 77.31%-80.92%, 74.41%-78.50%, 71.13%-74.35%, 64.49%-68.56%, 63.57%-68.23%), IOS (0.12-0.21, 0.14-0.34, 0.14-0.31, 0.19-0.40, 0.19-0.56, 0.21-0.49), EOS (0.12-0.30, 0.14-0.34, 0.16-0.41, 0.20-0.39, 0.22-0.58, 0.22-0.54), IOS/EOS (0.55-1.12, 0.52-1.45, 0.56-1.26, 0.54-1.38, 0.54-1.52, 0.65-1.46). The differences of ECI, HR, IOS and EOS in different groups were statistically significant (all P<0.05). Spearman correlation analysis results showed that ECI, IOS, and EOS were positively correlated with gestational week( rs=0.524, 0.689, 0.609; all P<0.01). HR was negatively correlated with gestational week ( rs=-0.755, P<0.01). The regression equations of ECI, HR, IOS and EOS were Y=0.06X+ 52.214, Y=99.25-1.07X, Y=8.63E-3X+ 0.05, Y=7.94E-3X+ 0.1, respectively. Conclusions:The normal parameters values of E-TVES are summarized.It provides effective support in data for cervical evaluation in the preterm prediction and success of labor induction.

Objective To observe the effect of transcutaneous electrical acupoint stimulation(TEAS)on circulation depression in patients underwent thoracoscopic radical resection of lung cancer under general anesthesia combined with thoracic paravertebral block(TPVB).Methods A total of 150 patients from Octomber 2021 to May 2022,58 males and 92 females,aged 19-64 years,BMI 18-30 kg/m2,ASA physical status Ⅰ or Ⅱ,underwent thoracoscopic radical resection of lung cancer under general anesthesia combined with TPVB were enrolled.According to random number table method,the patients were divided into two groups:the TEAS group and the control group,75 patients in each group.In the TEAS group,transcutaneous electrical acupoint stimulation was performed at Hegu,Neiguan,and Zusanli 30 minutes be-fore induction until the end of operation.In the control group,the electrodes were only connected at the same time point without electrical stimulation.HR,SBP,DBP,MAP,and BIS were recorded before stimu-lation(T0),10 minutes after TPVB(T1),the time of skin incision(T2),30 minutes after operation star-ted(T3),60 minutes after operation started(T4),the end of operation(T5),and 30 minutes after opera-tion(T6).The incidences of bradycardia,tachycardia,hypotension,and hypertension,and the usages of vasoactive drugs during operation were recorded.The dosages of propofol,sufentanil,and remifentanil in the operation were recorded.The VAS pain score 1,2,and 7 days after operation,the usages of analgesics used within 7 days after operation,postoperative adverse effects such as nausea and vomiting,dizziness,chest tightness,and shortness of breath,and the length of hospital stay were recorded.Results Compared with the control group,intraoperative infusion volume,incidence of hypotension,hypertension,and circulation depression,the usages of deoxyepinephrine,ephedrine,norepinephrine,and urapidil intraoperation,VAS pain scores 1 and 2 days after operation,and the usage of analgesics within 7 days after operation were sig-nificantly decreased(P＜0.05),length of hospital stay was significantly shortened(P＜0.05),SBP,DBP,and MAP were significantly increased at T1(P＜0.05),the dosagesof propofol,sufentanil,and remifentanil were significantly decreased in the TEAS group(P＜0.05).There were no significantly differ-ences of nausea and vomiting,dizziness,and shortness of breath between the two groups.Conclusion TEAS can improve the circulation depression,and reduce the incidences of intraoperative hypotension and hypertension,decrease the dosages of anesthetics and the rate of using vasoactive drugs during operation,improve early postoperative acute pain and shorten the length of hospital stay in patients undergoing thoraco-scopic radical resection of lung cancer under general anesthesia combined with TPVB.

Objective:To evaluate the development of fetal cerebral sulci and gyrus and the blood perfusion in pregnant women with gestational diabetes mellitus(GDM) by ultrasound.Methods:A total of 1 540 pregnant women with 28-34 weeks of pregnancy who underwent systematic screening in Henan Provincial People′s Hospital from January 2022 to October 2022 were prospectively selected, 100 pregnant women with GDM were selected as the GDM group. According to the effect of blood glucose control, the GDM group was divided into 2 groups: the satisfied control group (GDM group 1), and the dissatisfied control group (GDM group 2), with 50 cases in each group. At the same period, 50 healthy pregnant women at 28-34 weeks of gestation were enrolled as the control group. The differences of the sylvian fissure, parietooccipital sulci, calcarine sulci and cinguli sulci among the 3 groups were statistically analyzed. And the correlations between the deep of the brain cerebral sulci and gyrus and controlled blood glucose levels were evaluated. The umbilical artery pulsation index(UAPI), middle cerebral artery pulsation index(MCAPI) and ductus venosus pulsation index(DVPI) among the 3 groups were compared, and the differences in fetal blood perfusion among the 3 groups were evaluated.Results:There were no significant differences in the depths of the sylvian fissure, parietooccipital sulci, calcarine sulci and cinguli sulci between the control group and the GDM group 1 (all P>0.05), and they were larger than those of the GDM group 2 (all P<0.05). The depths of lateral fissure, parieto-occipital sulcus, cingulate sulcus and calcarine sulcus were negatively correlated with fasting blood glucose, 1 h and 2 h postprandial blood glucose (all P<0.05). There were no significant differences in MCAPI, UAPI and DVPI between the control group and GDM1 group (all P>0.05). The MCAPI in GDM 2 group was lower than that in the control group and GDM 1 group, and the UAPI and DVPI values were higher than those in the control group and GDM1 group(all P<0.05). Conclusions:The maturity of fetal cerebral sulci and gyrus in GDM pregnant women is related to the blood glucose control of pregnant women. The change of blood perfusion caused by persistent hyperglycemia in pregnant women and intrauterine hypoxia may cause the development retardation of cerebral sulci and gyrus.
