Objective To observe the clinical efficacy of intradermal needle plus acupoint application with Da Huang (Radix et Rhizoma Rhei) in preventing constipation after craniocerebral injury. Method Two hundred patients with acute craniocerebral injury were randomized into a treatment group and a control group, 100 cases each. The control group received conventional nursing care to prevent constipation, while the treatment group was additionally treated with intradermal needle plus acupoint application with Da Huang (Radix et Rhizoma Rhei). The occurrence of constipation within a week was observed in the two groups. Result The occurrence rate of constipation was 12.0％ in the treatment group versus 32.0％ in the control group, and the between-group difference was statistically significant (P<0.05). Conclusion Intradermal needle plus acupoint application can effectively reduce the frequency of constipation in patients with acute craniocerebral injury.

BACKGROUNDIt is known that excessive release of glutamate can induce excitotoxicity in neurons and lead to seizure. Dexamethasone has anti-seizure function. The aim of this study was to investigate glutamate-dexamethasone interaction in the pathogenesis of epilepsy, identify differentially expressed genes in the hippocampus of glutamate-induced epileptic rats by mRNA differential display, and observe the effects of dexamethasone on these genes expression.

METHODSSeizure models were established by injecting 5 microl (250 microg/microl) monosodium glutamate (MSG) into the lateral cerebral ventricle in rats. Dexamethasone (5 mg/kg) was injected intraperitoneally at 30 minutes after MSG inducing convulsion. The rats' behavior and electroencephalogram (EEG) were then recorded for 1 hour. The effects of dexamethasone on gene expression were observed in MSG-induced epileptic rats at 1 hour and 6 hours after the onset of seizure by mRNA differential display. The differentially expressed genes were confirmed by Dot blot.

RESULTSEEG and behaviors showed that MSG did induce seizure, and dexamethasone could clearly alleviate the symptom. mRNA differential display showed that MSG increased the expression of some genes in epileptic rats and dexamethasone could downregulate their expression. From more than 10 differentially expressed cDNA fragments, we identified a 226 bp cDNA fragment that was expressed higher in the hippocampus of epileptic rats than that in the control group. Its expression was reduced after the administration of dexamethasone. Sequence analysis and protein alignment showed that the predicted amino acid sequence of this cDNA fragment kept 43% identity to agmatinase, a member of the ureohydrolase superfamily.

CONCLUSIONSThe results of the current study suggest that the product of the 226 bp cDNA has a function similar to agmatinase. Dexamethasone might relax alleviate seizure by inhibiting expression of the gene.

An adult man of methylmalonic acidemia combined with hyperhomocysteinemia is reported. He presented with progressive walking instability with mental and behavioral alterations when aged 24 years. Physical examination showed significant cerebellar ataxia and pyramidal signs. Brain magnetic resonance imaging revealed symmetric lesions of bilateral cerebellum. His plasma total homocysteine and urine methylmalonic acid were significantly elevated. Compound heterozygous mutations, c.482G>A and c.217C>T, were found in his MMACHC gene, confirming the diagnosis of cblC deficiency. Improved clinical manifestations and decreased plasma total homocysteine were observed one month after treatment.

Objective To investigate epidemiologieal characteristics of hypothyroidism and factors influencing its outcome in the areas with different iodine intakes.Methods An epidemiologic follow-up study of thyroid diseases was performed in Panshan (iodine deficient),Zhangwu [mild iodine deficiency before universal salt iodination (USI) and more than adequate iodine intakes after USI ] and Huanghua ( iodine excessive) in China.A total of 3 761 subjects were investigated in 1999,and 3 018 (80.2% ) of them were followed up in 2004.FT_4,FT_3,TSH,thyroid autoantibodies and urinary iodine concentration were determined and thyroid B ultrasound was performed in all participants.Results Five-year cumulative incidence of overt hypothyroidism was 0.23%,0.47% and 0.35% in Panshan,Zhangwu and Huanghua,respectively.Twenty patients with autoimmune- induced overt hypothyroidism did not comply with the physician's orders to take thyroxine.Thyroid function spontaneously turned to normal in 55% of them,turned to subclinical hypothyroidism in 20% and maintained overt hypothyroidism in 25%.Five-year cumulative incidence of subclinical hypothyroidism in Zhangwu (2.60%) and Huanghua (2.89%) were significantly higher than that in Panshan(0.23% ) (both P＜0.01 ).One hundred patients with subclinical hypothyroidism were followed up,and 5% of them developed overt hypothyroidism,66% turned to euthyroidism and 29% maintained subclinical hypothyroidism.Raised serum TSH (＞6 mU/L) in the original survey ( OR = 3.4),positive thyroid autoantibodies in the follow-up study ( OR = 5.3 ) and more than adequate iodine supplementation in the mild iodine-deficient population ( OR = 8.0) were risk factors influencing outcome of subclinical hypothyroidism.Conclusion More than adequate iodine supplementation among a population in the mildly iodine-deficient area may increase the incidence of overt and subolinical hypothyroidism, and also influence outcome of subclinical hypothyroidism.

Objective To evaluate the relationship between iodine intake level and the occurrence and development of thyroid diseases.Methods During the period of 1999-2004,a cross-sectional survey in 1999 and a 5-year follow-up survey were conducted in the 3 communities with different iodine intake levels in China:Panshan (mild deficiency),Zhangwu (more than adequate) and Huanghua (iodine excess).A total of 3 761 subjects were included in 1999 and 80.24% of them participated in the 5-year follow-up survey in 2004.The levels of serum thyroid hormones and thyroid autoantibodies were measured,and thyroid B ultrasound was performed.Results (1) The prevalence of overt hypothyroidism in 1999 in Zhangwu and Huanghua was 3.5 and 7.3 times,and that of subclinical hypothyroidism was 3.2 and 6.6 times as high as in Panshan,respectively.The 5-year cumulative incidence of subclinical hypothyroidism was 11.3 and 12.6 times as high as in Panshan,but no difference of incidence of overt hypothyroidism was found.(2) The prevalence of autoimmune thyroiditis (AIT) in 1999 in Zhangwu and Huanghua was 3.8 and 6.2 times,and the S-year cumulative incidence of AIT was 4.4 and 5.5 times as high as in Panshan.(3) During the 5-year follow-up period,the incidences of hypothyroidism in subjects with positive thyroid peroxidase antibody and euthyreidism in Zhangwu and Huanghua were 4.2 and 10.3 times as high as in Panshan.(4) No significant differences in both prevalence in 1999 and 5-year cumulative incidence of overt hyperthyroidism were found in the 3 communities.(5) The incidence of thyroid cancer was 19.37/100 000 per year in Huanghua,and all of the cases were papillary thyroid cancer,and no thyroid cancer was found in Zhangwu and Huanghua.Conclusion More than adequate or excessive dietary iodine intake may induce and promote the occurrence and development of hypothyroidism and AIT,therefore,median urinary iodine excretion (MUI)more than 200?g/L in the population appears not safe.The observation that a higher incidence of thyroid cancer occurred in the iodine excessive areas with MUI 600?g/L deserves further investigation.

OBJECTIVETo study the expressions of differential proteins in the expressed prostatic secretion (EPS) of patients with III A chronic prostatitis and healthy men.

METHODSWe collected EPS samples from 35 patients with III A chronic prostatitis and 18 age-matched healthy men, and detected the differentially expressed proteins in EPS by MALDI-TOF/MS. Based on the data obtained, we conducted a statistical analysis on the mass-to-charge (m/z) ratios of different proteins and a retrieval analysis on the relevant proteins using the protein database.

RESULTSIn the comparative studies of the III A chronic prostatitis patients and healthy men, 5 proteins were detected as at least 2-fold differentially expressed, which were probably brevinin-2Eg, big endothelin-1, alpha-defensin 15, beta-defensin 134 and prostatic steroid-binding protein C2. The m/z ratios were significantly up-regulated in 3 372, 3 487, 425 and 5 325 Da proteins (P < 0.01) and down-regulated in 10631Da (P < 0.01).

CONCLUSIONProteins are differentially expressed in the EPS of III A chronic prostatitis patients and healthy men, and these proteins may be significantly correlated with the development and progression of III A chronic prostatitis.

OBJECTIVE: To investigate the incidence of neonatal asphyxia and possible contributing factors for the development of severe asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture, China. METHODS: A total of 16 hospitals in Hubei Enshi Tujia and Miao Autonomous Prefecture were selected as research centers. A retrospective analysis was performed for the clinical data of 22 294 live births in these 16 hospitals from January to December, 2016 to investigate the incidence rate of neonatal asphyxia and possible contributing factors for the development of severe asphyxia. RESULTS: Of the 22 294 neonates born alive, 733 (3.29%) were diagnosed with neonatal asphyxia, among whom 627 had mild asphyxia and 106 had severe asphyxia. The neonates with low maternal education level, maternal anemia during pregnancy, chorioamnionitis, abnormal amniotic fluid, abnormal umbilical cord, placenta previa, placental abruption, Tujia Minority, preterm birth, and low birth weight had a higher incidence of severe asphyxia (P<0.05). CONCLUSIONS The incidence rate of neonatal asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture is higher. Low maternal education level, maternal anemia during pregnancy, chorioamnionitis, abnormal amniotic fluid, abnormal umbilical cord, placenta previa, placental abruption, Tujia Minority, preterm birth, and low birth weight may be related to the development of severe neonatal asphyxia.

Coronavirus disease-2019 (COVID-19) outbreaks were spreading rapidly around the world in early 2020. This disease is within the category of "damp epidemic" and "damp toxin epidemic" in traditional Chinese medicine, with lung and spleen as the lesion focuses, while dampness and toxin as especially prominent properties. Through clinical observation, we found that dampness would often transform into damp heat during the development and evolution of the disease, and the "triple energizer" treatment was an important therapeutic method, eliminating pathogens through purgation and diuresis: for those with damp-heat accumulation toxin diffused to the triple energizer, we could use Ganlu Xiaodudan as primary prescription, which can spread the upper part, smooth the middle part and infiltrate the lower part, so as to provide a way out for the pathogenic factors and regulate Qi movement. For those with damp-heat in Shaoyang channel, we could use Haoqin Qingdantang to clear heat and promote diuresis, harmonize Shaoyang, eliminate damp-heat and epidemic pathogenic factor. For those with pathogen hidden in membrane source dampness trapping and hidden heat, we could use Dayuanyin to eliminate pathogens between interior and exterior parts, and regulate Qi movement. At the same time we shared three typical cases treated in Wuhan, and conducted an in-depth analysis in this study. Clinically, the method of elimination of pathogens through purgation and diuresis is mainly used in the early and middle stage of this disease. When the disease is still located in Qi system, it also can be applied to mild, ordinary patients and severe patients that have accurate syndrome differentiation. In such cases, it can effectively improve symptoms, reduce pathogenic toxin, truncate and reverse the course of disease, give way to pathogen, and avoid disease aggravating.
