ABSTRACT

Objective:To explore the epidemiological characteristics and clinical outcomes of patients diagnosed with novel coronavirus (COVID-19) pneumonia (NCP), and to provide clinical reference for subsequent epidemic prevention and control.Methods:The pathogenesis, clinical characteristics and clinical outcomes of 62 patients with imported novel coronavirus COVID-19 pneumonia in Qingdao area from January 21, 2020 to April 6, 2020 were analyzed.Results:There were 24 males and 38 females, aged from 5 to 91 (52.5±15.7)years. Among them, 31 cases (31/62, 50%) were family cluster disease, 11 cases (17.74%) were nosocomial cross infection, 14 cases (22.58%) came back from Wuhan to Qingdao and community contact infection, and 6 cases (9.68%) were imported from abroad. The longest time from fever to diagnosis was 26 days. Clinical classification: 40 cases were mild, 13 were general, 7 were severe, 2 were critically ill. 61 cases were discharged from hospital, and 1 was dead. The clinical cure rate was 98.39%. The average stay was (18.5±4.8)days. All patients were treated combined with Chinese medicine on the basis of symptomatic treatment.Conclusions:The clinical symptoms of imported NCP are relatively mild, and mild cases were more, the recovery rate was higher. The intervention strategy of traditional Chinese medicine is conducive to rehabilitation. The external input cases and symptomless infected patients are important for epidemic situation in the future.

ABSTRACT

@#AIM: To investigate the clinical efficacy and safety of the foldable capsular vitreous body(FCVB)implantation in the treatment of severe ocular trauma and also explore the effect of ciliary body function on the FCVB implantation. <p>METHODS: This study retrospectively analyzed 10 cases(10 eyes)with severe ocular trauma which had accepted FCVB implantation performed in Affiliated Xiaolan People's Hospital, Southern Medical University from January 2018 to July 2020. Ciliary body function was judged by score which was made by preoperative examination results. The case which scored 5 or less was studied as ciliary failure: 8 eyes scored more than 5, 2 eyes scored 5 or less. Followed up for 1-31mo, the postoperative best corrected visual acuity(BCVA)and intraocular pressure, anterior chamber, retinal reattachment, FCVB condition and adverse reactions were observed. <p>RESULTS: The operations of 9 eyes with aphakia eyes were successful. Iridodialysis occurred during the operation of 1 eye with lens. Retinal reattachment was found in all 10 eyes, and the position of FCVB in all patients was proper. There was no severe adverse reactions. Comparing the preoperative and postoperative BCVA and intraocular pressure, the difference was not statistically significant(<i>P</i>>0.05). In the group(8 eyes)that ciliary body function scored more than 5, 2 eyes had a supplementary operation individually, 1 eye underwent 2 supplementary operations. In the group(2 eyes)which scored 5 or less, supplementary operations were performed 5 times in 1 eye, only 1 time in the other one case. <p>CONCLUSION: Implantation of FCVB is a safe option to treat severe ocular trauma. But the postoperative visual acuity cannot be improved. The ciliary body function associates with persistent intraocular hypotension and shallow anterior chamber after FCVB implantation.

ABSTRACT

Objective:To systematically evaluate the effect of SRSF2 gene mutation on the prognosis of patients with myelodysplastic syndromes (MDS).Methods:Databases including PubMed, Embase and Cochrane Library were searched for relevant studies that conducted the effect of SRSF2 gene mutation on the prognosis of MDS. The retrieval time limit was from the time of establishing database to December 2018. All cohort studies related to the effect of SRSF2 gene mutation on the prognosis of MDS were screened according to the inclusion and exclusion criteria. Data extraction and bias risk assessment were conducted for the eligible literature. The observation indicators were statistically analyzed by using RevMan 5.3 software.Results:A total of 11 studies were included in the final Meta-analysis. Compared with MDS patients without SRSF2 mutation, MDS patients with SRSF2 mutation had shorter overall survival time (HR = 1.67, 95% CI 1.40-2.00, P < 0.01) and progression-free survival time (HR = 6.20, 95% CI 2.64-14.58, P < 0.01). MDS patients with SRSF2 mutation was easier to transform into acute myeloid leukemia (AML) with shorter time (HR = 2.02, 95% CI 1.49-2.74, P < 0.01) compared to patients without SRSF2 mutation.Conclusion:SRSF2 gene mutation is an independent poor prognosis factor in patients with MDS.

ABSTRACT

Objective To observe the effect of fenofibrate intervention on high-fructose-feeding-induced liver steatosis in rats and explore the possible mechanism. Methods Male Wistar rats were randomly divided into control group ,high fructose group and fenofibrate group[fenofibrate intervention started after 8 weeks of high fructose feeding ,30 mg/(kg · d)]. Rats were sacrificed after 12-week of high fructose feeding. Serum alanine aminotransferase(ALT),aspartate aminotransferase(AST),total cholesterol(TC),free triglyceride(TG)and liver TG content were determined;protein levels of fatty acid synthase(FAS),endoplasmic reticulum stress mark-er Bip and autophagy markers such as Atg7,Beclin1,LC3 and the related pathway mTOR in liver tissues were de-tected. Results Compared with those in control group and fenofibrate group,serum AST,serum total cholesterol, blood free TG and hepatic TG were significantly increased in high-fructose group(P < 0.01). The protein expres-sion of Fas,Bip and mTOR were significantly increased in high-fructose group compared with those in control group and fenofibrate group;the protein expression of Atg7,beclin1 and LC3 were significantly decreased in high-fructose group compared with those in control group and fenofibrate group. Conclusions Long-term high-fructose-feeding induces fatty liver and liver cell injury ,and may affect ERS and autophagy. High-fructose-feeding-in-duced fatty liver may be improved by fenofibrate and its underlying mechanism might be associated with Fas,ERS and autophagy in liver.

ABSTRACT

Stroke research and rehabilitation have traditionally focused on the physical and functional impact of a stroke. Less attention has been given to the psychosocial factors associated with this chronic condition. By the few studies that have specifically focused on psychosocial factors in the context of stroke, poststroke depression is demonstrated to significantly influence stroke outcomes. Associations of stroke with psychological symptoms other than depression have rarely been evaluated. This study was aimed to investigate the changes of psychological stress, social support and medication adherence in patients with ischemic stroke in the mainland of China. In this study, 90 patients with hemiplegia one year after first-ever middle cerebral artery infarction (stroke group) in the Zhongnan Hospital of Wuhan University from June 2008 to June 2011 were recruited for interview. Ninety age- and sex-matched normal volunteers (control group) were also examined at the same period. The psychological distress was assessed by the Symptom Checklist 90 (SCL-90), the social support by the Social Support Rating Scale (SSRS), and medication adherence by Morisky's self-reported inventory, respectively. Group differences were analyzed using unpaired-t test and chi-squared test. The results showed that total mean scores of the SCL-90 in the stroke group were higher than those in the control group (P<0.01). Except two dimensions, paranoid ideation and psychoticism, mean scores of the rest dimensions (including somatization, obsession-compulsion, interpersonal sensitivity, depression, anxiety, hostility, and phobic anxiety) of SCL-90 were significantly higher in the stroke group than those in the control group (P<0.05, or P<0.01). The objective support, subjective support, support availability and total social support scores in the stroke group were significantly higher than those in the control group (P<0.05, or P<0.01). Those in the "SCL-90 total scores >150 group" were significantly higher than in the "SCL-90 total scores <100 group" and the "SCL-90 total scores between 100 to 150 group" (P<0.05, or P<0.01). Those in the "SCL-90 total scores between 100 to 150 group" were significantly higher than in the "SCL-90 total scores <100 group" (P<0.05). In 90 patients with ischemic stroke, 26 (28.89%) patients obtained high medication adherence, 47 (52.22%) patients medium medication adherence, and 17 (18.89%) patients low medication adherence, respectively. Among these stroke patients, there were 17 (50.00%) patients with high medication adherence in the "SCL-90 total scores >150 group", 28 (75.67%) patients with medium medication adherence in the "SCL-90 total scores between 100 to 150 group", and 12 (61.16%) patients with low medication adherence in the "SCL-90 total scores <100 group", respectively. There was significant difference in the medication adherence rate among the different SCL-90 scores groups in these stroke patients (P<0.05 or P<0.01). It was led to conclude that ischemic stroke patients one year after hemiplegia have psychological distress, low level of social support and poor medication adherence in the mainland of China. Therefore, it is necessary to mobilize the government, medical institutions and various social support groups to offer psychological interventions to relieve the stress of patients with ischemic stroke, and improve their medication adherence.

ABSTRACT

Objective To explore the effect of dietary fat acids on incretin and islet function in healthy adults .Methods Before each test, healthy subjects received a 1-week pre-experiment eucaloric diet .Fifteen subjects consumed two meals containing different fat acids , including high saturated fat acid ( HSF) and high monounsaturated fat acid ( HMF) .On two separate occasions,they underwent a minimum of 1-week washout between meals .At 0,30,60,120,180 and 240 min following meal intake, the plasma concentrations of gastric inhibitory polypeptide (GIP), glucagon-like peptide-1(GLP-1) and serum concentrations of glucose, insulin, triglycerides ( TG) and free fatty acid ( FFA) were measured.Results Postprandial glucose did not increase significantly following HSF and HMF meals (P>0.05).Compared with HMF meal, significant increase in AUCins240min,AUCTG240min and AUCFFA240minwas observed following HSF meal (P0.05). AUCI/AUCG was significantly lower following HMF meal as compared with HSF meal (P<0.05).Conclusion This study demonstrates that the function of GIP ,GLP-1 andβcell is affected by the dietary fat acids in healthy adults .The HMF meal may stimulate GIP and GLP-1 secretion to a greater extent than HSF meal .

ABSTRACT

<p><b>OBJECTIVE</b>To study expression of the zinc finger transcriptional factor Snail in colorectal carcinoma and its significance.</p><p><b>METHODS</b>Expressions of Snail in colorectal carcinoma SW480 and SW620 cells were assayed by immunocytochemistry and immunofluorescent cytochemistry. The paraffin-embedded specimens from 68 cases of colorectal carcinoma and its corresponding adjacent tissues, 33 cases of adenoma and 35 cases of metastatic lymph nodes were also examined for Snail expressions using immunohistochemistry.</p><p><b>RESULTS</b>Snail protein was located mainly in the cell nucleus of SW480 and SW620 cells. The expressions of PRL-3 protein in the specimens of colorectal carcinoma, normal mucosa, adenoma and metastatic lymph nodes were significantly different (Chi(2)=92.852, P=0.000). In the adenoma tissues, the expression was significantly higher than that in normal mucosa (Z=-2.902, P=0.004), the metastatic lymphnodes had significantly higher expressions than the primary colorectal carcinomas (Z=-4.951, P=0.000), which, in turn, showed significantly higher expression than the adenoma tissues (Z=-3.572, P=0.000). Significant correlation of Snail expression was found to the progression and metastasis of colorectal carcinoma (Z=-2.043, P=0.041).</p><p><b>CONCLUSION</b>The expression of Snail is significantly correlated to genesis, progression and metastasis of colorectal carcinoma.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To explore the levels of serum vitamin B(12) (VB(12)) in preschool children, determine the relationship between the levels of serum VB(12) and anemia, and analyze the effects of several factors related to the level of serum VB(12).</p><p><b>METHODS</b>From March 2005 to July 2005, the weight, height and complete blood count (CBC) were studied in 351 children aged 2 to 7 years from 4 kindergartens of Chongqing. The concentrations of serum VB(12) and the dietary survey of 177 of the children were evaluated.</p><p><b>RESULTS</b>The average level of serum VB(12) for the preschool children was 552 pg/ml. The levels of serum VB(12) in 4.5% (8/177) of the children were below 200 pg/ml (defined as VB(12) deficiency), in 10.7% (19/177) of the children were 200 - 300 pg/ml (called marginal deficiency). There were no significant differences in the levels of serum VB(12) between boys and girls. And there was no correlation between the levels of serum VB(12) and hemoglobin. The results of multivariate stepwise regression analysis showed that the concentrations of serum VB(12) were mainly influenced by the contents of VB(12) in the foods (P = 0.03). Eight of the children with normal growth and development were diagnosed as VB(12) deficiency, only one of them was diagnosed microcytic hypochromatic anemia. The ranges of Hb, MCV and MHC were normal in the other 7 children.</p><p><b>CONCLUSIONS</b>The levels of serum VB(12) of preschool children were higher than that of adults, suggesting that the levels of serum VB(12) change with age. There were no significant differences in the levels of serum VB(12) in 2-7 years old children between sex and ages. The levels of serum VB(12) were not correlated with the concentrations of hemoglobin. Macrocytic anemia may not occur in preschool children with VB(12) deficiency. The intake of VB(12) from the diets was one of the important factors for preschool children to keep the normal ranges of serum VB(12). It is beneficial for children to consume foods enriched with VB(12) to keep the normal level of serum VB(12).</p>
