ABSTRACT
Objective@#We investigated changes in the intestinal flora of children with Mycoplasma pneumoniae pneumonia (MPP).@*Methods@#Between September 2019 and November 2019, stool samples from 14 children with MPP from The Fourth Hospital of Baotou city, Inner Mongolia Autonomous Region, were collected and divided into general treatment (AF) and probiotic (AFY) groups, according to the treatment of "combined Bifidobacterium, Lactobacillus, Enterococcus, and Bacillus cereus tablets live". High-throughput 16S rDNA sequencing was used to identify intestinal flora.@*Results@#Intestinal flora abundance and diversity in children with MPP were decreased. Both Shannon and Simpson indices were lower in the AF group when compared with healthy controls ( P < 0.05). When compared with healthy controls, the proportion of Enterorhabdus was lower in the AF group, while the proportion of Lachnoclostridium was higher ( P < 0.05). The proportion of Bifidobacteria and Akkermansia was lower in the AFY group but Enterococcus, Lachnoclostridium, Roseburia, and Erysipelatoclostridium proportions were higher. The proportion of Escherichia coli- Shigella in the AFY group after treatment was decreased ( P < 0.05).@*Conclusions@#The intestinal flora of children with MPP is disturbed, manifested as decreased abundance and diversity, and decreased Bifidobacteria. Our probiotic mixture partly improved intestinal flora disorders.

ABSTRACT
OBJECTIVE: To investigate the relationship between pathogenesis of PBB and the T cell subsets disorders and to evaluate the clinical significance of immunomodulatory therapy to the prognosis of PBB and the prevention of recurrent PBB. METHODS: A total of 127 cases of PBB children treated in the Fourth Hospital of Baotou City from May2015 to May 2018 were selected. Blood samples were collected before treatment,and the levels of CD4,CD8 cells and CD4/CD8 in peripheral blood T cell subsets were detected by flow cytometry. All children with PBB(PBB group)were given oral amoxicillin and clavulanate potassium for 2 to 4 weeks. The subjects were divided into Huaiqihuang group(n=66)and non-Huaiqihuang group(n=66). The Huaiqihuang group was given Huaiqihuang granules based on the anti-infective treatment. In addition,healthy children were enrolled as control group(n=39). T cell subsets of the two groups were reexamined 3 months after treatment. By analyzing the cough symptom scores of all children after 2 weeks,4 weeks and 12 weeks of treatment,the rate of cure and improvement and the recurrence rate after 1 year were evaluated.SPSS16.0 software was used for data processing,and the difference was significant if P0.05). In 2 weeks after treatment,the cough symptom scores of the PBB group began to decrease,and the non-Huaiqihuang group decreased more significantly,with statistically significant difference(P0.05). Follow-up showed that the recurrence rate of Huaiqihuang group was lower than that of non-Huaiqihuang group in 1 year after the end of treatment,and the difference between the two groups was statistically significant(P<0.01). CONCLUSION: Children with PBB have T cell subsets disorder,and the treatment of anti-infection combined with Huaiqihuang granules for at least 4 weeks has a positive effect on PBB prognosis and recurrence prevention.
ABSTRACT
Astrocytes are the most abundant cells in the central nervous system, which has been demonstrated to be one of the targets for the treatment of ischemic stroke. Many studies have confirmed that acupuncture can effectively regulate astrocyte activity in ischemic stroke through these approaches: repairing astrocyte morphology structure, regu-lating energy metabolism, inhibiting excitotoxicity, inhibiting inflammation response and promoting nerve regeneration. In this paper, the authors summarized the relationship between astrocyte and ischemic stroke, and discussed the mechanisms of acupuncture therapy underlying improvement of ischemic stroke. Additionally, the authors also put forward some suggestions about future researches on acupuncture in ischemic stroke.

METHODS:The management measures of prescriptions audit and intervention before payment in our hospital were introduced. 1 200 outpatient pre-scriptions within 1 year before and after management were subjected to a statistical analysis. The effects of prescriptions audit be-fore payment were evaluated through analyzing and comparing qualification rate of prescription and unqualified prescriptions. RE-SULTS:Our hospital adopted a series of measure to realize prescriptions audit and intervention before payment by clinical pharma-cists,such as using information audit system,formulating audit standard,educating pharmacists,establishing audit job system, prescriptions review and feedback system,setting up communication system,etc. Of the total audited 189 665 prescriptions, 14 581(7.69%)failed to audit and 606 prescriptions hadn’t been revised after 1 year management,with effective intervention rate of 95.84%. Compared with before management,the prescription qualification rate increased from 88.83% to 98.67% after manage-ment(P<0.01). The quantity of overdose,inconformity with medical insurance,overload and other conditions reduced to 0. CON-CLUSIONS:It is feasible for pharmacists to audit and intervent prescriptions before payment in hospital pharmacy to improve pre-scription qualification and promote rational drug use in the clinic.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the effects of prophylactic administration of all-trans retinoic acid (ATRA) in relieving inflammation in a rat model of collagen-induced arthritis (CIA).</p><p><b>METHODS</b>Female Wistar rats (6 to 8 weeks old) were randomly divided into normal control group, solvent control group, and prophylactic ATRA treatment (0.05, 0.5, and 5 mg/kg) groups. All the rats except for those in normal control group were subjected to subcutaneous injection of type II collagen and incomplete Freund adjuvant in the tails to induce CIA, followed by injection on the following day with saline, corn oil or different doses of ATRA 3 times a week. The arthritis index (AI) scores, histological scores, serum levels of TNF-α, IL-17A, and IL-10, and expressions of proteases related with cartilage damage were evaluated.</p><p><b>RESULTS</b>On the 15th day after the primary immunization, the AI scores increased significantly in all but the normal control groups; the scores increased progressively in all the 3 ATRA groups but remained lower than that in the solvent control group, which was stable over time. The rats in the 3 ATRA groups showed obvious pathologies in the knee and ankle joints, but the semi-quantitative scores of pathology damage showed no significance among them. Compared with those in solvent control group, the serum IL-17A and TNF-α levels decreased, serum IL-10 level increased, and the expressions of ADAMT-4 and MMP-3 proteins decreased significantly in the knees in the 3 ATRA groups.</p><p><b>CONCLUSION</b>ATRA can reduce the production of TNF-α and IL-17A and increase the production of IL-10 to alleviate the inflammation in rats with CIA. ATRA may delay the progression of RA by correcting the imbalance of Th1/Th2 and Th17/Treg.</p>

ABSTRACT
To study the hemolytic effect of polyphyllin II (PP II) mediated by anion channel protein and glucose transporter 1 (GLUT1), in order to initially reveal its hemolytic mechanism in vitro. In the experiment, the spectrophotometric method was adopted to detect the hemolysis of PP II in vitro and the effect of anion channel-related solution and blocker, glucose channel-related inhibitor and multi-target drugs dehydroepiandrosterone (DHEA) and diazepam on the hemolysis of PP II. The scanning electron microscope and transmission electron microscope were used to observe the effect of PP II on erythrocyte (RBC) morphology. The results showed that PP II -processed blood cells were severely deformed into spherocytes, acanthocyturia and vesicae. According to the results of the PP II hemolysis experiment in vitro, the anion hypertonic solution LiCl, NaHCO3, Na2SO4 and PBS significantly inhibited the hemolysis induced by PP II (P < 0.05), while blockers NPPB and DIDS remarkably promoted it (P < 0.01). Hyperosmotic sodium chloride, fructose and glucose at specific concentrations notably antagonized the hemolysis induced by PP II (P < 0.05). The glucose channel inhibitor Cytochalasin B and verapamil remarkably antagonized the hemolysis induced by PP II (P < 0.01). The hemolysis induced by PP II could also be antagonized by 1 gmol x L(1) diazepam and 100 μmol x L(-1) DHEA pretreated for 1 min (P < 0.01). In conclusion, the hemolytic mechanism of PP II in vitro may be related to the increase in intracellular osmotic pressure and rupture of erythrocytes by changing the anion channel transport activity, with GLUT1 as the major competitive interaction site.

The patients' age grades in other group and digestive system had two climax age groups, which the one was 21 ～ 30, and the other was above 70. The patients' age grades in poisoning group was by far among 21 ～ 50, which the patients' amount of acute alcoholism was at the most. (4) In 12 568 cases of death group, the death amount of circulatory system, other group, respiratory system, nervous system and digestive system ranked at the lst,2nd,4th,5th 8th respectively, whose age grades was by far above 51, especially above 70,and the patients' amount of sudden cardiac death was at the most in the death amount of circulatory system. The death amount of trauma and poisoning group ranked at the 3rd, 6th respectively, whose age grades was by far among 21 ～ 50. (5)The total amount, the death amount and the sudden cardiac death amount of male patients were more than those of female patients. (6)The percentage of the death group to the pre-hospital medical care group was 5.20%, and the percentage of the sudden cardiac death group to the pre-hospital medical care group was 1.29%,and the percentage of the sudden cardiac death group to the death group was 24.87 %, and the percentage of the sudden cardiac death group to the circulatory system group was 67.33 %. Conclusions ( 1 )The trauma and the sudden cardiac death are the overriding reason of disease and the overriding reason of death in our large and medium-sized cities respectively. (2) It is very important to cut the death rate of the middle-old age patients by strengthening prevention and cure of cardiovascular and cerebrovascular diseases, discerning the critical illness early and improving the level of pre-hospital medical care. (3)It is a strong method to decrease the total amount and the death amount of the trauma, especially in traffic accident, by strengthening safety in production, observing traffic regulation and enhancing the legal awareness.
ABSTRACT
Objective To investigate the effects and values of extracorporeal membrane oxygenation (EC-MO) used in patients after cardiac arrest. Method During five years period from June 2002 to June 2007,fifteen cases taken for cardiopulmonary resuscitation were treated by using ECMO in the emergency department and ICU. All the measures for disgnosis and treatment were observed to the guidelines for cardiopulmonary resuscitation and emergency cardiovasculat care set by the American Heart Association in 2005, and ECMO was applied in addition. The study was a self-comparison trial. The biomarkers including heart rate (HR), mean arterial pressure (MAP), central venous pressure( CVP) , arterial partial oxygen pressure (PaO2), arterial partial pressure of carbon dioxide ( PCQ2), oxygen saturation (SaO2), hydrogen power (PH), and concentration of lactic acid were taken and assayed before and 10 min, 1 h,6 h, 12 h, and 24 h after treatment. Differences between the results of measurements were analysed by t -test for matched pairs using SPSS version 10.0 software package. Neurological sequelae was also observed and described. Results Ten minutes after ECMO treatment, MAP rose dramatically (P < 0.01) and got to further higher level one hour later ( P < 0.05). On the other hand, CVP dropped off 10 minutes after ECMO treatment and further lowered one hour later, and PaO2 and SaO2 were improved apparently ( P < 0.01), and pH was increased significantly (P < 0.01), while a derease in concentration of arterial LA of significantly (P < 0.01). Of the 15 cases, 11 patients got well,including completely recovered without sequelae in 5,memory disorders in 2 and hemipleggia in 2 patients. Conclusions ECMO provides effective blood flow to hearts, and therefore, improves oxygenation and oxygen consumption greatly. Moreover, it provides stable oxygenated blood to brain and therefore, it is a good approach to cardiopulmonary cerebral resuscitation.
ABSTRACT
[Objective]To investigate the regular pattern of references quoted in theses of Orthopedic Journal of China from year 2005 to 2006,and to study the characteristics and experiences of reference quoting in Chinese orthopedic academic sphere.[Method]Forty-eight issues of Orthopedic Journal of China from year 2005 to 2006 were downloaded from the website www.chinajournal.net.cn.There were 466 theses about clinical research.All references in these theses were collected as origin of data.Excel software was applied to analyze all references.[Result]References were found in all 466 papers with the reference rate of 100%.The average reference amount in each thesis was 7.15(3 334/466).A total of 3110 references were from journals(93.28%)and 214 references were from monographs(6.42%).The Price Index reached 52.13%.And the number of self-quoted references reached 614 with the rate of self-quoting of 18.42%(614/3 334).References from Chinese and foreign journals with the first 20 highest being-quoting rates were collected,and it reached 56.12% of all references.[Conclusion]The content of references in Orthopedic Journal of China ranges widely.The main quoting origin is from journals.The mainly-quoted language is English,and references from other languages are rarely quoted.Most references showed new and original ideas.
