Objective The analysis of correlation between the occurrence of tourette syndrome with one-child family environment. Methods The authors investigated home environment of two groups. One group included 200 patients with tourette syndrome and is the other group included healthy children of the same age in 3 different primary and secondary schools. By comparing with the home environmental factors, parenting styles and parent emotional factors between two groups. Results The instabilities of home environment included bad family relationship, separation between parents, divorce, scolding and even beating children. It showed that anxiety of the direct supervisors among the sickness group were higher than healthy control group as well. Among the ten factors of the Family Environments Scale, the significant differences showed in six factors of affection,cohesion,expressiveness, conflict, intellectual-culture orientation, active-recreational orientation, organization between the two groups. Conclusion So we concluded that ①There is a correlation between the parents relations,parenting styles and the incidence of tourette syndrome; ②An anxiety of the direct supervisor may initiate, even aggravate the incidence of tourette syndrome; ③It is important to convert the education mode and take family overall treatment in order to reduce the incidence and improve the effectiveness of tourette syndrome.

Objective To investigate the effects of crude extracted proteins from lesions of condyloma acuminata on immunophenotypes of dendritic cells.Methods Plastic-adherent mononuclear cells(MNCs)were isolated from umbilical cord blood or peripheral blood and cultured in media containing cytokines(GM-CSF,IL-4and LPS).The morphology and phenotypes of these cells were analyzed by flow cytometry and microscopy in12day's culture.Cells on the fourth day were incubated with crude extracts from lesions of condyloma acuminata,foreskin proteins,and PBS,respectively,followed by phenotypic analysis after9-12days' culture.Results Expression of antigens CD1a,CD80,CD86,MHC-I,MHC-II,CD14,CD54was detected after12days' cul-ture.It was shown that MNCs could be induced to differentiate to mature dendritic cells in our culture system.After incubation with crude extracts from lesions of condyloma acuminata for another9-12days,expression of CD86and HLA-DR was increased on dendritic cells.Conclusions Compared to foreskin and PBS pulsed dendritic cells,expression of CD86and HLA-DR is upregulated on dentritic cells after pulsing with condyloma acuminata lesion proteins.The data suggest that crude extracts from lesions of condyloma acuminata might enhance antigen-pre-senting capacity of dendritic cells and strengthen activation of T lymphocytes.

AIM: To study the role of post-hemorrhagic shock mesenteric lymph (PHSML) drainage on the balance of angiotensin-converting enzyme ( ACE) and ACE2 in the kidney.METHODS:A hemorrhagic shock model was established and then fluid resuscitation was performed to the animals in shock and shock+drainage groups, and the PHMSL was drained in shock+drainage group after fluid resuscitation.After 6 h of resuscitation, the mRNA expression of ACE, ACE2, angiotensin II (Ang II) type 1 receptor (AT1R) and Mas-related G-protein-coupled receptor (MasR), and the levels of Ang II and Ang (1-7) in the renal tissues were observed.RESULTS:Hemorrhagic shock increased the levels of ACE mRNA, AT1R mRNA and Ang II, and decreased the levels of ACE2 mRNA, MasR mRNA and Ang(1-7) in the kid-ney.PHSML drainage abolished the effect of hemorrhagic shock on ACE2 and AT1R mRNA expression.Meanwhile, PHSML drainage reduced the hemorrhagic shock-induced increases in the ratios of ACE/ACE2, Ang II/Ang(1-7) and AT1R/MasR.CONCLUSION:The PHSML drainage restores the balance of ACE/ACE2, which is beneficial to alleviate acute kidney injury following hemorrhagic shock in the mice.

OBJECTIVETo evaluate the effectiveness of a helium-oxygen mixture (79%He- 21%O(2)) as an aerosolizing compressed gas for beta(2)-agonist therapy in patients with an asthma exacerbation.

METHODSTwenty-four patients in the outpatient department with a mild to moderate exacerbation of asthma were enrolled. The patients were randomly divided into an experimental group (13 cases) and a control group (11 cases). The experimental group inhaled Berotec with heliox-driven, and the control group inhaled Berotec with compressed air-driven. Eight hospitalized patients in the respiratory department with severe exacerbation of asthma were enrolled. The patients inhaled Berotec with heliox-driven or compressed air-driven in a random order.

RESULTSThe results of spirometric parameters and arterial blood-gas analysis were measured. In the mild to moderate asthma patients, no statistical differences between the two groups for forced vital capacity (FVC), forced expired volume in one second (FEV(1)), and expiratory flow in 50% forced vital capacity (FEF(50)) were presented. But the severe patients showed significant differences between heliox-driven and compressed air-driven for FVC, FEV(1), FEF(50) and partial pressure of oxygen (PaO(2)).

CONCLUSIONSCompared with the traditional inhalation of beta(2)-agonist therapy using compressed air-driven, the method of inhaling beta(2)-agonist with heliox-driven has more obvious benefits for those suffering from severe asthma. This is likely due to the cooperative effects between inhaling heliox on its physical gas properties and improving delivery of beta(2)-agonist in the treatment of exacerbation of severe asthma.

OBJECTIVETo observe dynamic changes of blood lead concentration in rats with long-term toxicity test with Goupi Gao by the flame atomic absorption spectrometry, in order to provide reference for safe administration of Goupi Gao.

METHODThe rats were administered with Goupi Gao by high-dose (7 g x kg(-1)), medium-dose (3.5 g x kg(-1)), low-dose (1.75 g x kg(-1)) by external use for consecutively 90 days. Then, the blood samples were collected from the rats before the administration and at 10, 30, 45, 52, 60, 90 d after the administration respectively, as well as 16 d and 28 d after the drug withdrawal. The samples were dispelled with microwave digestion system and then were determined by graphite furnace atomic absorption spectrometry for blood lead levels.

RESULTAccording to methodological study, the standard curve regression equation in this experiment was A = 0.004 9X + 0. 017, r = 0.999 5, with the detection limit up to 0. 380 microg x L(-1). The RSD was 1.4% by precision checks. Blood lead level of mixed blood samples was 175.77 microg x L(-1), whose RSD was 6. 0%. Blood lead concentration gradually increased after low-dose and medium-dose administration to rats and became stable at the 10th day and the 30th day by high-dose. Dose is directly related to blood lead concentration. Meanwhile, the blood lead concentration decreases after the drug withdrawal.

CONCLUSIONThe method of determination in this experiment is so accurate and reliable that it can be used for the determination of blood lead. Long-term and high-dose external use of Goupi Gao can increase blood lead.

Objective:To analyze the factors influencing the difference in location of cricothyroid membrane between traditional surface palpation and ultrasonic biplane.Methods:One hundred and seven subjects of both sexes, aged 18 yr, underwent neck ultrasound examination in our hospital from August 2021 to December 2021, were selected.The structure of cervical airway was observed by ultrasound.The subjects in whom the structure of cricothyroid membrane was clearly shown were selected.The middle point of cricothyroid membrane was located by otorhinolaryngologist using surface palpation method and by ultrasonic doctor using ultrasonic biplane method.The distance between two positioning points was measured by a ruler.The subjects were divided into accurate group (distance between two points≤3 mm) and difference group (distance between two points>3 mm). The distance between cricoid cartilage and thyroid cartilage (spacing of cricoid cartilage and thyroid cartilage) and distance between the midpoint of cricothyroid membrane and skin (spacing of cricothyroid membrane and skin) were measured by ultrasound.The neck length and the maximum submaxillary distance in head up were measured by a ruler.The factors influencing the difference in location between the two methods were analyzed by multivariate logistic regression.Results:One hundred and four subjects with clear cricoid cartilage and cricothyroid membrane under ultrasound were selected.There were significant differences in the ratio of gender, body mass index (BMI), cricothyroid membrane-skin distance, neck length, and maximum submandibular distance between the two groups ( P<0.05). Multivariate logistic analysis showed that female ( OR=9.091, P<0.001), BMI ( OR=11.214, P=0.001) and increased cricothyroid membrane-skin distance ( OR=5.649, P=0.015) were the factors influencing the difference in location between the two cricothyroid membrane localization methods. Conclusions:Female, obesity (BMI>28.0 kg/m 2) and increased distance between cricothyroid membrane and skin are the factors affecting the difference in location of cricothyroid membrane between ultrasonic biplane method and surface palpation method, and bedside ultrasound is recommended for location in those with the factors mentioned above.

The unique multi perspective and magni-fying effect of laparoscopic surgery make gastric surgery more precise and minimally invasive. The technical innovation of 4K laparoscopy enable surgeons to understand the finer submicrostructure-membrane anatomy. The advantages of perigastric lymph node dissection with less trauma and bleeding under the guidance of membrane anatomy theory are widely recognized. As a common metastatic site of advanced distal gastric cancer, lymph nodes in the infrapyloric region play an important role in radical gastrectomy. Blood vessels variation is common in the inferior pyloric region, and the layer between gastric and mesenteric membrane is complex. Complete resection of the right gastric omentum membrane can yield greater surgical benefits. In this article, the author discuss the key points of lymph node dissection in the subpyloric region based on their surgical experience, aiming to promote the standard surgical procedure of 4K laparoscopic lymph node dissection in the inferior pyloric region based on membrane anatomy.

OBJECTIVETo investigate the safety of different level of tween 80 by comparing the degree of pseudoanaphylactoid reactions (PR) induced by medicinal tween 80 and injectable tween 80.

METHODThe analysis of vascular permeability of the mice ears: ICR mouse were divided into different test groups, the mice were intravenously injected with solutions of medicinal tween 80 and injectable tween 80 with 0.2%, 1% and 5% concentration, positive control Compound 48/80 and 5% glucose injection. All test substances were mixed with 0.4% Evans blue. The reaction and vascular permeability of the ears were observed and measured 30 min after injection. The analysis of vascular permeability of the rat's skin: the rats were intravenous injected with 0. 6% Evans blue normal saline solution first, 10 minutes later, the same substances were intradermal administrated into the back of rats. The rats were sacrificed and the diameter of locus ceruleus and the content of Evans blue leak out were measured 20 min after injection.

RESULTMedicinal tween 80 and injectable tween 80 with 5% concentration caused obvious vascular hyper permeability in ICR mice, but the degree of vascular hyperpermeability caused by injectable tween 80 was lighter than by medicinal tween 80. Other tween 80 didn't cause obvious vascular hyper permeability in the ears of mouse. The solution of different concentration of tween 80 caused obvious locus ceruleus reaction in rat's back. As for the content Evans blue leak out, there was no statistical significance between each group except positive control Compound 48/80 group.

CONCLUSIONTween 80 can cause obvious vascular hyper permeability and the effect is dose dependent, which indicated that tween 80 can cause PR. On the other hand, injectable tween 80 is more security than medicinal tween 80, the dosage of tween 80 should be still controlled strictly so that to decrease the incidence of PR.
