Objective:To explore the effect of early exercise rehabilitation in patients with acute myocardial infarction (AMI).Methods:A total of 64 AMI patients with stable vital signs were randomly divided into early exercise reha-bilitation group (n=32)and routine rehabilitation group (n=32)according to number table method.Early exercise rehabilitation group received early exercise rehabilitation guidance by rehabilitation therapists on first day after on-set,while routine rehabilitation group received exercise rehabilitation guidance by rehabilitation therapists of same qualification after one-week absolute bed rest.Besides,the two groups received same therapy and nursing.Incidence of major adverse cardiovascular events (MACE:re-infarction,death,severe arrhythmias,angina pectoris after in-farction and heart failure),hospitalization days and condktion of life self-care ability were observed,compared and analyzed between two groups.Results:Before discharge,there were no significant difference in MACE incidence rate (40.63% vs.43.75%)and percentages of patients with life self-care ability (100% vs.96.88%)between early exercise rehabilitation group and routine rehabilitation group,P >0.05,but length of hospital stay in early rehabili-tation group [(9.23±1.45)d]was significantly shorter than that of routine rehabilitation group [(15.03±2.53) d],P <0.01. Conclusion:Early exercise rehabilitation training can shorten length of hospital stay and is safe in pa-tients with acute myocardial infarction.

anti p62 2 in patients with cancers All of them were lower than that of autoantibody against full length p62 The frequency of autoantibody to full length p62 was significantly higher than that of anti p62 2 and anti p62 3, but no difference with anti p62 1 Totally positive rates of autoantibody against the three fragments were lower than those of full length p62 in patients with hepatocellular cancer, gastric cancer, colorectal cancer, esophagus cancer and breast cancer but with lung cancer Conclusion:Antigenic sites in p62 were mainly located in p62 1 and the integrity of p62 structure is important for antigenic expression

Objective:To observe the fumigating insecticidal activity of 5 essential oils(asteraceae oil,rutaceae oil,mentha piperita oil,carvacryl oil and citronella oil) against Culex pipiens quinquefasciatus.Methods: Fumigating insecticidal activity was investigated by airtight fumigation in conical flask.Results: After different fumigating time,5 essential oils showed different toxity against Culex pipien quinqucfasciatus.Of 5 essential oils,rutaceae oil was the most toxic, with the LC 50 values being 0.013(0.5 h),0.055(4 h) and 0.058(24 h); asteraceae oil was the lowest toxic one, with the LC 50 values being 0.948(0.5 h),0.427(4 h) and 1.711(24 h).When LC 95 values of the 5 essential oils were used to treat Culex pipiens quinquefasciatus,the shortest fumigating time appeared in carvacryl oil(6.087 min) and the longest in citrinella oil(21.143 min).Conclusion: All the 5 essential oils have considerable insecticidal effects against Culex pipiens quinquefasciatus.Rutaceae oil and carvacryl oil are better than the others,which provides basic informations for the related field experiments.

Objective To summarize the value of early mechanical ventilation plus continuous vacuum suction in treatment of serious pulmonary contusion.Methods Forty-eight cases of severe pulmonary contusion were assigned to mechanical ventilation plus continuous vacuum suction (observation group,n =20) and mechanical ventilation plus discontinuous vacuum suction (control group,n =28)according to the random number table.Modes of mechanical ventilation were synchronized intermittent mandatory ventilation (SIMV),pressure support ventilation (PSV),and positive and expiratory pressure (PEEP).Changes in blood gas analysis,mechanical ventilation time,and associated complications were compared between groups.Results At ventilation time of 6 and 24 hours,PaO2 in observation group was (100.36 ± 5.90) mmHg and (105.34 ± 7.40) mmHg respectively,with significant differences from (75.36 ± 8.95) mmHg and (76.36 ± 8.35) mmHg in control group (P ＜ 0.01).At ventilation time of 24 hours,PaO2/FiO2 was (283.50 ± 15.20) mmHg in observation group and (201.50 ± 10.20) mmHg in control group (P ＜0.01).Mechanical ventilation time and PEEP at ventilation time of 48 hours in observation group was (3.2 ± 1.1) days and (4.5 ± 2.3) cmH2 O,with significant differences from (6.5 ± 2.8) days and (8.5 ± 2.5) cmH2O in control group (P ＜ 0.01).Associated complications of the two groups revealed no significant difference (P ＞ 0.05).Conclusion Early mechanical ventilation with sustained vacuum suction is effective to keep airway clear,improve oxygenation index,decrease PEEP level,and control the duration of mechanical ventilation,but may not lower the risks of ventilator-associated pneumonia and pulmonary atelectasis.

Objective:To analyze the clinical characteristics of adult abdominal migraine (AM), and improve the understanding and the accuracy of diagnosis of this disease.Methods:A case of adult AM diagnosed in the First Affiliated Hospital of Zhengzhou University in October 2019 was reported, and patients diagnosed with AM in the medical literature from January 2004 to May 2020 were searched and summarized.Results:A total of 634 articles were retrieved, among which 14 articles reported 17 adult AM patients,totally 18 adult AM patients (11 females),including the case diagnosed in the First Affiliated Hospital of Zhengzhou University. Only two cases were diagnosed within one year after the onset, and the other cases were diagnosed several years later, of which the longest diagnostic delay was 37 years. The location and nature of abdominal pain were diverse. The median frequency of episodes was 2.5 times per month. Sixteen patients had a duration of 2-72 hours per attack, and the longest one lasted for four days. Fourteen patients had nausea, 13 had vomiting, and seven had headache. Fifteen patients had a personal or family history of migraine. Sixteen patients′ episodes were separated by weeks to months. Because nonsteroidal anti-inflammatory drugs were not beneficial to adults with AM, abortive triptan therapy was recommended and anesthetics were considered when necessary. All patients responded to prophylactic migraine therapies.Conclusions:Adult AM is a rare disease. Patients with unexplained, recurrent and moderate to severe abdominal pain, combined with headache, a personal or family history of migraine, are highly suspected of having AM. Early diagnosis and prophylactic migraine therapies could contribute to good prognosis.

Objective To investigate the effects of early estrogen replacement therapy(ERT) with different doses on aortic endothelial senescence and its possible mechanism. Methods Twenty- eight healthy New Zealand white female rabbits were randomized into four groups: group A(n=7), in sham operation;group B(n=7), ovariectomized;group C(n=7), ovariectomized and in low-dose ERT(estradiol benzoate 200 μg,im, QOD) ;and group D(n=7), ovariectomized and in high-dose ERT (estradiol benzoate 1000 μg,im,QOD). All rabbits were fed with high fat diet and the rabbits in group C and group D were given ERT from the 7th day after the operation. Blood samples taken via ear central artery before the operation and after the high fat diet for 4 and 12 weeks were used to determine the concentrations of serum estradiol(E2), total cholesterol(TC), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), trigtyceride (TG) and asymmetric dimethylarginine(ADMA). After 12 weeks, the aorta was separated for histopathologic analysis and the areas of senescent endothelium and atherosclerotic plaque were calculated.Results (1)After ovariectomized, the concentration of serum estradiol(E2) was significantly lower in group B than in other groups (all P<0.05). Twelve weeks later, the level of E2in was higher group D than in group A and C(both P<0. 05), but there was no significant difference between group C and group A (P< 0. 05). (2)After the high-fat diet for 4 and 12 weeks, there was a notable increase of TC, LDL-C, TG and HDL-C levels in rabbits of each group(all P<0. 01). After 12 weeks, the levels of TC and LDL- C were remarkably higher in group B than in other groups(all P<0. 01), however, the levels of TG and HDL-C were lower in group B than in other groups(all P<0. 01). The concentrations of TC and LDL-C in group C and group D were lower than those in group A (all P<0.01), but the differences of the levels of TG and HDL-C in group C and group D were not significant in comparison with group A (all P>0. 05). There were no significant differences in the lipid levels between group C and D (all P> 0. 05). (3)After 12-week high fat diet, there were a striking increases of serum ADMA level in all four groups (all P>0. 05). The level of ADMA was higher in group B than in other groups (P< 0. 05) andlower in group C and D than that in group A (both P<0. 05). There was no significant difference between group C and D (P<0. 05). (4)12 weeks later, the areas of senescent endothelium and atherosclerotic plaque in group B were significantly larger than those in other groups (all P< 0. 01), and the areas were smaller in group C and D than those in group A (all P<0. 01), there was no significant difference between group C and group D(both P>0.05). (5)Linear correlation analysis showed that there was an obvious positive correlation between the areas of senescent endothelium and atherosclerotic plaque(r=0. 962, P<0. 01), and both of them were positively correlated with the levels of serum AMDA (r=0. 812,0. 824,0. 755,0. 797,0. 749,0. 727), TC (r=0. 812,0. 824) and LDL-C(r=0. 755,0. 797) (all P<0. 01) and negatively correlated with the concentration of serum E2 (r=-0. 762,-0. 743, both P<0. 01).Conclusions Early ERT can improve serum lipid metabolism, reduce ADMA level, inhibit vascular endothelial senescence and attenuate atherogenesis. The delaying effect of estrogen on endothelial senescence may be due to its improving lipid metabolism and lowering ADMA level.

Objective To evaluate the effects of 6-week atypical antipsychotics treatment on serum brain-derived neurotrophic factor (BDNF)level,and the correlation between BDNF level and clinical efficiency in first-episode antipsychotic-na?ve schizophrenia.Methods We recruited 39 hospitalized patients with first-episode antipsychotic-na?ve schizophrenia that met with Diagnostic and Statistical Manual of Mental Disorders—4th Edition (DSM-IV).Both Positive and Negative Syndrome Scale (PANSS)and the level of serum BDNF were measured before and after 6 weeks’treatment with atypical antipsychotics.We also studied 30 healthy controls.Serum BDNF was assayed at baseline.Results Pre-treatment BDNF level was significantly lower in the schizophrenic patients than in the controls [(6.82±2.1 5 )μg/L vs .(1 1.6 ± 3.32 )μg/L,t = 7.239,P < 0.001 ].Although BDNF level increased with treatment (t =2.349,P =0.021)in the schizophrenics,post-treatment BDNF level was still lower than in the normal controls (t =4.634,P <0.001).After 6 weeks’treatment for schizophrenia,the total score of PANSS,the scores of positive and negative symptoms,and the score of general psychopathology scale were all decreased (t =6.1 64,P < 0.001;t = 4.520,P < 0.001;t = 4.132,P < 0.001;t = 5.142,P < 0.001 ).Pre-treatment BDNF levels were directly correlated not only with the rate of decreased PANSS total score (r =0.348, P <0.05),but also with the rate of decreased negative symptoms score (r = 0.35 1,P < 0.05 ).However,pre-treatment BDNF levels were not correlated with improved positive symptoms,general psychopathology (r =0.204, 0.186,P >0.05),or duration of illness (r = - 0.058,P > 0.05 ).Changes in BDNF levels with treatment were correlated with the duration of illness (r =-0.345,P <0.05),but not with psychiatric improvement (r =0.036-0.1 74,P >0.05).Conclusion BDNF level is significantly lower in patients with first-episode antipsychotic-na?ve schizophrenia than in normal controls.It could be improved by using antipsychotics.Higher pre-treatment BDNF level may predict better response to antipsychotics.

Objective To study the features of treatment on neurochemical metabolites in prefrontal lobe and thalamus by proton magnetic resonance spectroscopy (1H-MRS) in first-episode drug-naive patients with early-onset schizophrenia (EOS).Methods Forty-two EOS (study group) met with Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition (DSM-Ⅳ) were recruited.Prefrontal lobe and thalamus were evaluated by multi-voxel 1H-MRS before and 4-week after treatment with a single atypical antipsychotic.The levels of N-acetylaspartate (NAA),creatine compounds (Cr) and choline-containing compounds (Cho) were measured.The patients also received Positive and Negative Syndrome Scale (PANSS).Forty normal controls (normal control group) underwent the same 1H-MRS detection.Results Before treatment,the NAA/Cr ratios in left prefrontal lobe,right prefrontal lobe and lefi thalamus in study group were lower than those in normal control group (1.45 ± 0.26 vs 1.60 ± 0.34,t =2.251,P =0.027;1.43 ±0.26 vs 1.60 ±0.35,t =2.505,P=0.014;1.48 ±0.27 vs 1.65 ±0.35,t =2.470,P =0.016).After 4-week treatment,the NAA/Cr ratios in both left prefrontal lobe and left thalamus of study group were significantly increased compared with those before treatment (1.58 ± 0.30 vs 1.45 ± 0.26,t =2.122,P =0.037;1.62 ± 0.32 vs 1.48 ± 0.27,t =2.167,P =0.033).After 4-week treatment in study group,the total score,positive symptom score,negative symptom score and general pathologic score of PANSS,and the total score of Clinical Global Impression (CGI) were significantly lower compared with those before treatment (59.1 ± 10.2 vs 82.0 ± 13.2,t =8.896,P=0.000;15.3 ±5.1 vs 22.9 ±7.1,t =5.634,P =0.000;16.4 ±5.2 vs 21.1 ±7.8,t =3.249,P =0.002;27.4 ±7.6 vs 38.1 ± 8.8,t =5.963,P =0.000;3.6 ± 0.4 vs 4.4 ± 0.5,t =8.097,P =0.000).There was no correlation between the changes of neurochemical metabolite levels such as NAA/Cr and Cho/Cr both in prefrontal lobe and left thalamus,and the clinical symptoms changes,such as total score and every score of PANSS,the total score of CGI in study group after treatment (all P ＞ 0.05).Conclusions The ratios of NAA/Cr are decreased not only in bilateral prefrontal lobe,but also in left thalamus,and the ratios may increase both in left prefrontal lobe and left thalamus after 4 weeks' treatment with atypical antipsychotics in EOS.The treatment outcomes of NAA/Cr do not agree with the improvement of the clinical symptoms.

Objective To analyze the characteristics of the primary headache due to cervicocerebral artery dissection (CAD).Methods A total of 146 consecutive patients with CAD in the First Affiliated Hospital of Zhengzhou University from 2010 to 2017 were observed.There were 20 cases who complained of primary headache,of which the characteristics of pain were analyzed according to their clinical features that were collected face to face through questionnaire.According to whether complicated by primary headache,the 146 patients were classified into two groups:20 cases (13.7％) in the primary headache group,and 126 cases (86.3％) in the non-primary headache group.Results Patients in the primary headache group had a lower prevalence of transient ischemic attack or cerebral infarction compared with the non-primary headache group (30.0％ (6/20) vs 77.0％ (97/126),x2=18.338,P＜0.01).CAD patients in the primary headache group were more likely involved in posterior circulation compared with the non-primary headache group (85.0％ (7/20) vs 55.6％ (70/126),x2=6.214,P=0.013).Of the 20 patients with primary headache,40.0％ (8/20) had continuous headache and 60.0％ (12/20) had intermittent headache;70.0％ (14/20) presented with severe headache,25.0％ (5/20) with moderate headache and 5.0％ (1/20) with mild headache;For the nature of pain,60.0％ (12/20) was similar to migraine;11/17 of patients with posterior circulation dissection showed occipital pain.Conclusions The primary headache caused by CAD is a severe pain occurring suddenly,and different from those of previous experiences.The nature of headache is often similar to migraine,which can be continuous or intermittent.In addition,compared with anterior circulation,patients with posterior circulation dissection often have headache as the initial symptom.

Objective:To summarize the clinical and imaging characteristics of anti-metabotropic glutamate receptor 5 (mGluR5) encephalitis, and improve clinicians' understanding of this encephalitis.Methods:The clinical data of one patient with anti-mGluR5 encephalitis admitted to our hospital from December 2020 were analyzed, and the data of 13 patients with anti-mGluR5 encephalitis reported in domestic and foreign databases were summarized and analyzed.Results:The main symptoms of 14 patients with anti-mGluR5 encephalitis included mental and behavior disorder (13/14), cognitive dysfunction (11/14), sleep dysfunction (9/14), seizures (8/14), decreased level of consciousness (6/14) and motor disorders (4/14). Four patients had abnormal brain MRI, including hyperintensity in the right mesial temporal lobe on T2 sequences, hyperintensity in the bilateral upper pons on T2 sequences, hyperintensity in the bilateral posterior parietal-occipital cortex on FLAIR sequences, and hyperintensity in the bilateral frontal lobes, right occipital lobe and cerebellum on T2/FLAIR sequences. Six patients had Hodgkin's lymphoma. Treatments included immunotherapy and oncologic therapy. Relapse was noted in 3 of the 14 patients, and symptoms improved significantly after immunotherapy. Except for one patient who died in hospital, 6 patients showed complete recovery and 7 patients showed partial recovery at the last follow-up (median 20 months).Conclusions:Anti-mGluR5 encephalitis is rare autoimmune encephalitis whose symptoms are not limited to the limbic system, and relapse may occur; immunotherapy has good effects; Hodgkin's lymphoma is often associated in these patients.
