RESUMEN
@#Abstract: Objective To analyze the epidemiological characteristics (season, age, gender, mixed infection and clinical manifestations, etc.) of Mycoplasma pneumoniae (MP) infection in children in Hainan Province, so as to provide epidemiological evidence-based medical basis for the prevention and control of MP infection in children in Hainan Province. Methods The serum IgM antibodies of MP, Legionella pneumophila, Chlamydia pneumoniae, adenovirus, respiratory syncytial virus (RSV), Q fever Rickettsia, parainfluenza virus, influenza A virus and influenza B virus in children with respiratory tract infections (RTIs) who were hospitalized in pediatrics of many hospitals in Hainan Province from March 2012 to February 2020 were detected by indirect immunofluorescence method. The positive serum MP-IgM antibody was defined as MP infection. The epidemiological and clinical data of MP infected cases were analyzed retrospectively. Results From March, 2012 to February, 2020, a total of 35 731 qualified pediatric inpatients with RTIs in many hospitals in Hainan Province were tested for serum MP-IgM with the total positive rate of 39.12% (13 978/35 731). The yearly positive rates of MP-IgM from 2012 to 2020 were 48.39%, 56.23%, 56.62%, 47.04%, 29.71%, 24.14%, 47.55%, 36.84% and 24.46% respectively. The positive rates of MP-IgM in 2013 and 2014 were significantly higher than those in other years (P<0.05). The positive rate of MP-IgM in summer in Hainan Province was the highest (41.34%) and the lowest in winter (35.77%) (P<0.05). MP infection occurred in all age groups, the positive rate of MP-IgM in children of preschool (51.80%) was significantly higher than that in other age groups (P<0.01), and the positive rate of MP IgM in children of infancy (15.36%) was lower than that in other age groups (P<0.01). The positive rate of MP-IgM in female was 44.77%, which was significantly higher than that in male (35.83%) (P<0.05). MP infection combined with positive IgM of another pathogen accounted for 32.63% (4 561 cases), positive IgM of another two pathogens accounted for 1.26% (176 cases). MP infection was mostly found in pneumonia (68.73%), and the main clinical symptoms were cough (84.72%), fever (51.01%) and wheezing (3.16%). Conclusions MP is an important pathogen of respiratory tract infection in children in Hainan Province, and infection is more common in children in early school age and early childhood. Mp-specific tests should be performed to identify the pathogen in children suspected of MP infection. In the high incidence season, health education should be strengthened in kindergartens, schools and other places to prevent respiratory tract infection.

RESUMEN
Q fever is a worldwide zoonosis and vaccination is the best measure to against its prevalence.Coxiella burnetii (Cb) is an obligate intracellular pathogen responsible for Q fever.Inactivated phase I Cb (Whole cell vaccine,WCV) can provide 100％ protection against Q fever,but its side effect of vaccination is strong.Phase I Cb is treated with chloroform-methanol or trichloroacetic acid and the chloroform-methanol residual (CMR) or the trichloroacetic acid extract (TCA) is used to substitute for WCV.Both CMR and TCA vaccine retain the protective efficient of WCV and significantly reduce the side effects.However,both CMR and TCA vaccine are required to isolate and purify Cb from chick embryos where Cb grows in a biosafety laboratory with the complex procedures.In recent 10 years,the scientists have investigated from protective antigens to CD4+ and CD8+ T cell epitopes of Cb,expecting that the genes encoding the T cell epitopes express highly and induce an efficient protection against Q fever in bodies.

RESUMEN
To explore the effect of releasing aqueous humor of anterior chamber through lateral incision of cornea in treating early elevated intraocular pressure ( lOP ) after implantation of implantable collamer lens ( lCL) .METHODS: Patients with elevated lOP were analyzed after lCL implantation. When the lOP>25mmHg, aqueous humor was released slowly through lateral incision of cornea, and made the lOP reduce to 10 ~13mmHg. After operation, lOP was measured every 2h. The releasing of aqueous humor was repeated until the lOP was decreased to normal.RESULTS: One hundred sixty - seven patients ( 330 eyes) were implanted lCL, while the lOP of 32 patients (62 eyes) was higher than 25mmHg after lCL implantation. Viscoelastic material was found in aqueous humor of most of high lOP patients, and the lOP of 48 eyes did not increase again through releasing aqueous humor once. The lOP of all these eyes was decreased to normal through releasing aqueous humor in 3 times at most. There were no abnormal in postoperative follow-up.CONCLUSlON:The main reason of early elevated lOP after lCL implantation is the remaining of viscoelastic material of eyes. Releasing aqueous humor through lateral incision of cornea can decrease lOP effectively. lt is a simple, safe, painless and repetition, which the patients are willing to accept.
RESUMEN
<p><b>OBJECTIVE</b>The aim of this study is to investigate whether microwave exposure would affect the N-methyl-D-aspartate receptor (NMDAR) signaling pathway to establish whether this plays a role in synaptic plasticity impairment.</p><p><b>METHODS</b>48 male Wistar rats were exposed to 30 mW/cm2 microwave for 10 min every other day for three times. Hippocampal structure was observed through H&E staining and transmission electron microscope. PC12 cells were exposed to 30 mW/cm2 microwave for 5 min and the synapse morphology was visualized with scanning electron microscope and atomic force microscope. The release of amino acid neurotransmitters and calcium influx were detected. The expressions of several key NMDAR signaling molecules were evaluated.</p><p><b>RESULTS</b>Microwave exposure caused injury in rat hippocampal structure and PC12 cells, especially the structure and quantity of synapses. The ratio of glutamic acid and gamma-aminobutyric acid neurotransmitters was increased and the intracellular calcium level was elevated in PC12 cells. A significant change in NMDAR subunits (NR1, NR2A, and NR2B) and related signaling molecules (Ca2+/calmodulin-dependent kinase II gamma and phosphorylated cAMP-response element binding protein) were examined.</p><p><b>CONCLUSION</b>30 mW/cm2 microwave exposure resulted in alterations of synaptic structure, amino acid neurotransmitter release and calcium influx. NMDAR signaling molecules were closely associated with impaired synaptic plasticity.</p>

This paper is aimed to study the effect of ADL on expression of β1-AR and M2-AchR in myocardial cells of rats exposed to microwave radiation. Immunohistochemistry, Western blot and image analysis were used to detect the expression of β1-AR and M2-AchR in myocardial cells at 7 and 14 d after microwave exposure. The results show that the expression level was higher in microwave exposure group and 0.75 g/(kg•d) ADL group than in sham operation group and significantly lower in 1.5 and 3.0 g/(kg•d) ADL groups than in microwave group. So we have a conclusion that the expression of β1-AR and M2-AchR is down-regulated in myocardial cells of rats exposed to microwave radiation. ADL can protect rats against microwave-induced heart tissue injury.

The therapy of removing beat and toxic,strengthening the body to cultivate the fundamental is the mainstream of treating cancer in traditional Chinese medicine up to now,and the therapy of warming yang has been rarely involved.While the pathogenesis of tumor is spleen and kidney yang deficiency in root,and phlegm,stasis,and poison entangled with each other at the secondary position; the main therapeutical principle of tumor is simultaneous application of purging-tonifying therapy while focusing on protecting yang.The author believes that the treatment of cancer should pay attention to the whole concept,especially warming yang for patients with advanced tumors.The therapy of warming yang is an effective way to get rid of phlegm and blood stasis.Patients after radiotherapy and chemotherapy should be paid more attention to warming yang.
RESUMEN
<p><b>OBJECTIVE</b>To investigate the origin of mixed germ cell tumors in the pineal region based on the image data, surgical findings and pathological examination of the tumor.</p><p><b>METHODS</b>The preoperative CT and magnetic resonance imaging (MRI) findings and tumor specimens were retrospectively analyzed in 15 cases of pineal mixed germ cell tumors confirmed by postoperative histological examination between January 2000 and September 2010.</p><p><b>RESULTS</b>Radiographic examination of the tumor revealed calcification in 12 cases, cystic changes in 10 cases, and the presence of lipid in 5 cases. On the anteroposterior images, the tumors appeared round or elliptic with smooth edge in 6 cases, and showed irregular shape with multiple processes on the edge in 9 cases. Surgical exploration found all the tumors located in the the suprapineal recess enclosed by the arachnoidal envelope of the Galen vein. Pathologically, 13 specimens contained germinoma component, 9 contained teratoma component, 4 had embryonic carcinoma component, 3 had choriocarcinoma component, 7 showed yolk sac tumor component, and 3 showed rhabdomyoma component. Germinoma components were found on the tumor margin in 7 specimens, and intermingled germinoma and other components were found in 10 specimens.</p><p><b>CONCLUSION</b>Pineal mixed germ cell tumor originates from the residue germ cells around the pineal gland, and most likely evolves from single primordial germ cells.</p>

Antiangiogenic therapy can generate a "normalization window" for tumor vasculature. This normalization process prunes immature vessels and improves the integrity and function of the remaining vasculature by enhancing the perivascular cell and basement membrane coverage in tumor, therefor creates a window of opportunity for improved sensitivity to ionizing radiation and the delivery of chemotherapeutic drugs. It provides a rational basis for the combination therapy of traditional Chinese drugs with radiation and perhaps other forms of chemotherapy. Antiangiogenic therapy with the traditional Chinese drug interfering in the the mechanisms of the normalization window in humans maybe harness a new approach to improve the sensitivity of tumors to radio- and chemotherapy.

<p><b>OBJECTIVE</b>To review the clinical manifestations, imaging, tumor markers, treatment methods, pathology results and clinical curative effects of pineal region tumors and to evaluate the characteristics and intervention strategies for those tumors.</p><p><b>METHODS</b>The clinicopathological data of 132 patients with pineal region tumor treated in our department between January 2000 and May 2008 were retrospectively studied.</p><p><b>RESULTS</b>A moderate predominance in males was presented. The clinical manifestations of the disease included increased intracranial pressure and ocular movement impairment. There were some features but no regularity and specific appearance on imaging including CT and MRI. 88.6% of patients associated with hydrocephalus. A high serum level of alpha-fetoprotein (AFP) was presented in 14 cases and high HCG in 9 cases. Eighteen cases received direct radiation therapy and 7 had radiotherapy post biopsy. 107 cases were treated surgically and 63 cases received postoperative adjuvant treatment. 114 cases had pathology results including 56 germ cell tumors. The patients were followed up for 12 approximately 132 months. Recurrence developed in 23 cases and 12 cases died. The 5-year survival rate was 89.3%.</p><p><b>CONCLUSION</b>Pineal region tumors are often associated with hydrocephalus and this makes preoperative diagnosis difficult. Imaging examination may help diagnosis but less specific. Germ cell tumors may diagnosed by some tumor markers. Radiation therapy is the choice of treatment for pure germinomas. Other types of pineal region tumors should receive surgical treatment. Postoperative adjuvant treatment based on pathology can provide a good prognosis in pineal region tumor.</p>

<p><b>OBJECTIVE</b>To analyze the factors contributing to the occurrence of diabetes insipidus after operations for craniopharyngiomas.</p><p><b>METHODS</b>A total of 121 cases of diabetes insipidus following surgeries for craniopharyngiomas were retrospectively analyzed and the factors associated with postoperative diabetes insipidus were analyzed.</p><p><b>RESULTS</b>The incidence of diabetes insipidus was 27.3% (33/121 cases) before the operation, 89.9% (107/1119) early after the operation and 39.8%(37/93) in later stages after the operation. The occurrence of early postoperative diabetes insipidus showed a significant relation to the classification and calcification of the craniopharyngioma. Patients with supradiaphragmatic and extraventricular tumors had the lowest incidence of postoperative diabetes insipidus. Late postoperative diabetes insipidus was closely correlated to such factors as age, classification of craniopharyngioma, and intraoperative treatment of the pituitary stalk, but not to the scope of tumor resection or tumor calcification. Late diabetes insipidus was more frequent in children and patients with severed pituitary stalk. The incidence of late postoperative diabetes insipidus was significantly higher in patients with supradiaphragmatic and extra-intraventricular tumors than in those with tumors beneath the diaphragma sellae and extraventricular tumors.</p><p><b>CONCLUSIONS</b>Postoperative diabetes insipidus following surgeries for craniopharyngiomas is closely related to the tumor classification, calcification and pituitary stalk protection.</p>

<p><b>OBJECTIVE</b>To explore the dynamic changes of serum interleukin-6 (IL-6) and IL-8 in acute traumatic brain injury (TBI) and their correlations to the severity of brain injury and the condition of the patients.</p><p><b>METHODS</b>Thirty-four patients with acute TBI were divided into two groups according to the Glasgow Coma Scale (GCS) score, clinical manifestations and the imaging data, namely patients with GCS score < or = 8 and those with GCS score between 9 and 12. Radioimmunoassay was employed to determine the serum levels of IL-6 and IL-8 at 6 different time points within 15 days after the injury in the two groups.</p><p><b>RESULTS</b>The serum IL-6 reached the peak level on the second day after the injury in patients with GCS score < or = 8 and on the 7th day in patients with GCS score of 9-12, showing significant differences in IL-6 variations between the two groups (P=0.046). The peak serum level of IL-8 occurred on the 7th day in patients with GCS score < or = 8 and on the 3rd day in patients with GCS score of 9-12, also showing significant differences (P=0.045). The peak level of IL-6 on the second day after the injury was significantly higher than the peak level of IL-8 that occurred on the 7th day, demonstrating significant differences in the variations of IL-6 and IL-8 after the injury (P=0.000).</p><p><b>CONCLUSION</b>The changes of serum IL-6 and IL-8 levels show positive correlations to the severity of the condition of the patients sustaining TBI. IL-6 variation is more obvious than that of IL-8 without intimate correlations between them. Clinically, serum IL-6 level can be more informative than serum IL-8 level in evaluating the changes of the condition of the TBI patients in early stage following the injury.</p>
