BACKGROUND:Delayed onset muscle soreness is closely related to skeletal muscle micro-injury, but the exact mechanism of skeletal muscle micro-injury is not yet clear. OBJECTIVE:To observe the histomorphological and ultrastructure changes of skeletal muscle micro-injury models induced by eccentric exercise. METHODS: Forty male Sprague-Dawley rats were randomly divided into quiet control group, immediately after exercise group, post-exercise 24 hours group, post-exercise 48 hours group and post-exercise 72 hours group. In the latter four groups, the rats were subjected to intermittent running on the-16° slope at a speed of 16 m/min: 5 minutes movement, 2 minutes rest and totaly 120 minutes. Rats in the latter four groups were observed immediately, at 24, 48, 72 hours after exercise. RESULTS AND CONCLUSION:After eccentric exercise, the morphology and ultrastructure of rat’s skeletal muscle were both changed to different extents, and Desmin and Vimentin were dyed off for anti-desmin antibody staining at varying degrees. It indicates that one-time eccentric exercise can cause delayed skeletal muscle micro-injury.

The clinical features and gene mutation characteristics of 2 children who suffered from Cornelia de Lange syndrome(CdLs)and were admitted to Affiliated Hospital of Zunyi Medical University in March 2019 were retrospectively analyzed.The 2 cases developed in infancy and presented with intractable epilepsy were accompanied with developmental retardation and special appearance.It was obvious that the 2 children had SMC1A gene mutations on X chromosome.Case 1 was frameshift mutations in the SMC1A gene at c. 2561dupA(p.K854fs), and case 2 was mutations in the SMC1A gene at c. 3441+ 1G>A(exon24)splicing mutation.These were heterozygous de novo mutations, and weren′t detected in their parents, which was not reported in literatures.In this study, 2 cases of CdLs were caused by SMC1A gene mutation, which enriched the human gene mutation database.CdLs should be considered in children with early-onset epilepsy, especially appearance and developmental retardation.Genetic testing is the most important diagnostic method.

Objective To investigate the prevalence features of helicobacter pylori (Hp) infection,anemia and iron deficiency in a po-pulation of Wuhan children with 2 to 6 years old,and the relationship between Hp infection and anemia,iron deficiency in the children.Methods Randomly taking 95 children who had taken tests in our hospital's check-up centre in 2008 as the study objects,2 kinds of exa-mination were employed to detect Hp infection.Serum levels of Hp-IgG were measured by enzyme linked immunosorbent assay (ELISA) methods to evaluate past infection.The 14C urea breath test (14C-UBT) was conducted to obtain information of the presence of current/active Hp infection.In the morning 3 mL fasting venous blood was collected to determine the serum levels of Hp-IgG antibodies and ferritin.Hemoglobin values were determined with a hemoglobinometer.Serum levels of C-reactive protein (CRP) were tested in order to determine whether the children had evidence of current inflammation or infection.In addition,demographic information such as age and gender of the children and information about their use of antibiotics within the prior month were recorded.All cases were divided into 2 groups including the Hp infection group and non-Hp infection group according to laboratory examinations,then the Logistic regression was applied to analyze the relationship between Hp infection and anemia,iron deficiency.The Kappa identity test was taked to compare the 2 measures.Results Of the 95 children,18.9% were anemic and 36.8% were iron deficient.Forty percent of the cohort had Hp-IgG antibodies,74.4% tested positive by the UBT.Presence of Hp-IgG emerged as a significant risk factor for anemia,iron deficiency in adjusted analysis controlling for demographic factors,current inflammation,and antibiotic use.Conclusions Findings from different measure of Hp may reflect different stages of infection,with UBT results reflecting an earlier stage of infection,and presence of Hp-IgG reflecting established Hp infection associated with anemia,iron deficiency.

OBJECTIVETo study the effect of acupuncture on the immune function of sepsis patients.

METHODSNinety sepsis patients were assigned to the control group, the thymosin a1 group, and the acupuncture treatment group according to random digit table, 30 patients in each group. Patients in the control group were treated according to the guideline of Surviving Sepsis Campaign (SSC). Patients in the control group received routine treatment. Those in the thymosin alpha1 group additionally received subdermal injection of thymosin alpha1 (1.6 mg), once per day for 6 successive days. Needling at related points such as Zusanli (ST36), Yanglingquan (GB34), Neiguan (PC6), Guanyuan (RN4), and so on, was performed in patients of the acupuncture treatment group, once per day for 6 successive days. T cell subgroups (CD3+, CD4+, CD8+, CD4+ /CD8+) and immunoglobulin levels (IgG, IgA, IgM) were detected. The length of ICU hospital stay, hospital readmission rate, and 28-day mortality were compared among the three groups.

RESULTSAfter six days of treatment, CD3+, CD4+, CD8+, IgG, IgA, IgM, and CD4+ /CD8+ ratio of three groups were all significantly increased (P < 0.01). Of them, CD3+, CD4+, CD8+, IgG, IgA, and IgM increased more significantly in the thymosin alpha1 group and the acupuncture treatment group (P < 0.01). Compared with the control group, the ICU hospitalization length was significantly shortened, the hospital readmission rate and the 28-day mortality were lower in the thymosin alpha1 group and the acupuncture treatment group (P < 0.05, P < 0.01). There was no statistical difference in each index between the thymosin alpha1 group and the acupuncture treatment group (P > 0.05).

CONCLUSIONAcupuncture could adjust the immune function of sepsis patients, improve their immunological indicators and prognoses.

Odor and taste are characteristic properties of traditional Chinese medicine (TCM). They are closely related to the chemical compositions in TCM. They are also the outer reflection of TCM quality and an important part of the character identification. This article reviewed the current research on odor and taste identification of TCM, which indicated that odor and taste identification had not been paid enough attention to and its research lagged behind modern social development. Based on current analytical techniques and methods, this article proposed a new idea for odor and taste identification of TCM. The idea emphasized the objectification of odor and taste and TCM identification research should be combined with chemical components analysis.

Objective To evaluate the possibilities of using circulating miR-155-5p, miR-21-5p, miR-29a and miR-142-5p as biomarkers for the diagnosis of active pulmonary tuberculosis (TB).Methods Plasma samples were collected from 60 healthy subjects, 40 patients with active pulmonary TB and 20 sub-jects with latent tuberculosis infection ( LTBI) to extract miRNAs.The levels of miR-155-5p, miR-21-5p, miR-29a and miR-142-5p in plasma samples were detected by using reverse transcription-quantitative PCR. Results The levels of miR-155-5p, miR-21-5p and miR-29a in patients with active pulmonary TB were re-spectively 10.13, 7.34 and 2.74 times as much as those in healthy subjects(P<0.05).No significant differences with the level of miR-142-5p were observed between the two groups.The receiver operating char-acteristic (ROC) curve analysis of miR-155-5p, miR-21-5p and miR-29a in patients with active pulmonary TB and healthy subjects showed that the areas under the curve (AUC) were respectively 0.905, 0.830 and 0.687.The level of miR-155-5p in patients with LTBI was 3.1 times than that in healthy subjects ( P<0. 05).No differences with miR-21-5p, miR-29a and miR-142-5p were found between patients with LTBI and healthy subjects.The levels of miR-155-5p, miR-21-5p and miR-29a in patients with active pulmonary TB were respectively 3.26, 6.69 and 1.98 times than those in patients with LTBI (P<0.05).The rate of LTBI was 40.58%in people who were in close contact with patients with active pulmonary TB.Conclusion Sig-nificant differences with the levels of miR-155-5p, miR-21-5p and miR-29a were observed among healthy subjects, patients with active pulmonary TB and patients with LTBI, but no difference with the level of miR-142-5p was observed among them.miR-155-5p, miR-21-5p and miR-29a could be used as the potential bio-markers for the diagnosis of active pulmonary tuberculosis and latent tuberculosis infection.People who were in close contact with patients with active pulmonary TB could have a higher LTBI rate.

Objective To explore the distribution characteristics of TCM syndrome and clinical relevant factors of benign prostatic hyperplasia (BPH).Methods Totally 781 cases of BPH patients were collected. Chi-square test, analysis of rank and inspection were used to detect the distribution characteristics of TCM syndrome. The multiple classification logistic regression was used to analyze related factors.Results BPH 14 kinds of distribution of syndromes were statistically significant (P<0.01). One of the highest incidence is qi deficiency and blood stasis syndrome (24.97%), and lung heat obstruction is the lowest (1.15%). Composite syndromes (529 cases) were more common than single syndrome (252 cases); syndromes of intermingled deficiency and excess (453 cases) were more common than simple excess (169 cases) or deficiency syndromes (159 cases). BPH single syndrome distribution was different in prostate volume, residual urine volume, maximum urine flow rate, and showed no difference in the serum PSA level. 3 logit model was established successfully. It was found that the patients with the features of 50 to 60 years old, the course < 3 years, I-PSS score for 8 to 19 points showed higher positive incidence of excess syndrome than intermingled deficiency and excess syndromes and deficiency syndrome.Conclusion This study reveals the BPH distribution characteristics and clinical related factors, which has guiding significance to improve TCM clinical level.

Objective To observe the peripheral arterial Doppler flow velocity curve changes and elucidate the blood flow characteristics by adding extra pressure on the limbs,and to provide evidence for better diagnosis of peripheral arterial diseases by ultrasound.Methods Color Doppler ultrasound instrument was used to record the brachial artery(BA),radial artery(RA),common femoral artery(CFA) and popliteal artery(POA) Doppler flow velocity curves both at rest and under different grades of distal and proximal limb pressuring in 40 randomly selected healthy adults.The peak systolic and early diastolic reverse flow velocity(PSV,PRV) and the resistance index (RI) were measured and analyzed.Results Three-phase waveform was seen at rest.Significant changes were noticed in PRV and RI under distal pressuring,while no significant difference was seen in PSV between groups.Conclusions Normal peripheral arteries show pulsed step-by-step blood flow pattern along with the cardiac cycles.Peripheral arterial Doppler flow curves changes regularly with limb grading pressuring.
