Objective To investigate the changes of serum C-reactive protein(CRP)and neu-ron-specific enolase(NSE)levels in patients with acute cerebral infarction(ACI)and their relations with in farct size,severity of neurological impairment.Methods The levels of serum CRP,NSE were measured in 60 patients(ACI group)within 72 hours after infarction and 40 normal controls(control group).The severity of neurological impairment of patients with ACl was assessed by National Institutes of Health Stroke Scale (NIHSS)at admission.Results The mean levels of serum CRP and NSE in ACI group were higher than those in control group, (6.95±2.34)mg/L vs(2.21±1.05)mg/L,P＜0.01, (22.39±4.72)μg/L vs(7.16±2.63)μg/L,P＜0.01,respectively.Higher levels of CRP and NSE were obviously associated with larger infarct size and more severe neurological impairment.The changes of CRP and NSE levels correlated with scores of NIHSS(r=0.51,r=0.44,all P＜0.01)significantly.CRP levels were positively correlated with those of NSE(r=0.57,P＜0.01).Conclusion The levels of serum CRP and NSE can be used as an important biological marker to estimate the size of infarct and the severity of neurological impairment in ACI.

Objective To evaluate the cognitive impairment and the related factors in patients after first lacunar infarct （LI）. Methods96 patients with LI and 40 controls were assessed with mini-mental state examination（MMSE）, digit span test （DST）, verbal fluency test （VFT）and clock drawing test （CDT）. ResultsThe scores of MMSE, DST, VFT and CDT were significantly lower in LI group than in control group (P＜0.05). Cognitive impairment occurred in 37 (38.5%) patients with LI after first stroke. The scores of MMSE, DST, VFT and CDT were lower in the patients with multiple infarcts than with single infarct (P＜0.05), and lower in patients with infarcts affecting the frontal lobe, thalamus and basal ganglia than affecting other area (P＜0.05). The scores of MMSE were lower in the patients with prior vascular risk factors than without risk factors (P＜0.05). ConclusionLacunar infarction usually leads to cognitive impairment. Cognitive function is associated with multiple infarcts, lesions affecting the frontal lobe, thalamus and basal ganglia and those with prior vascular risk factors.

Objective To evaluated the effectiveness and safety ofLianhua Jizhi Tablets for acute trachitis and bronchitis with syndrome of phlegm-heat obstructing.Methods A randomized double-blind, placebo-controlled and multi-center clinical trial design was selected. Totally 240 cases were randomly divided into experimental group and control group, 120 cases in each group, of which 237 cases were included in the analysis of FAS. Experimental group was givenLianhua Jizhi Tablets, while control group was given placebo, 12 tablets/day, 7 days for a course. Curative effect of acute trachitis and bronchitis, TCM syndrome and disappearance of cough, cough and sputum symptom scores and area under the curve (AUC) were observed. The safety was evaluated. Results The cure rates of disease in experimental group and control group were 66.67% (78/117) and 29.17% (35/120), respectively;cure rates of TCM syndrome in experimental group and the control group were 68.38% (80/117) and 27.50% (33/120), respectively;there was statistically significant difference in area under the curve of cough and sputum symptom score between the two groups (P<0.01). Disappearance rates (cure) of daytime cough in experimental group and control group were 52.99% (62/117) and 13.33% (16/120), respectively;disappearance rates (cure) of nocturnal cough in experimental group and control group were 76.52% (88/115) and 31.90% (37/116), respectively;there were no side effects in experimental group.ConclusionLianhua Jizhi Tablets can significantly relieve clinic symptoms in the treatment of acute trachitis and bronchitis, and have good clinical efficacy and safety.

Public health emergencies have an impact on the public mental health. The outbreak of the novel coronavirus has affected the normal diagnosis and treatment services in oral medical institutions across the country. Delay of non-emergency dental service will have a potential impact on the experience, cognition, treatment and rehabilitation of patients with oral diseases. Through literature review, this paper reviewed the oral psychosomatic diseases closely related to patients' psychological state, such as oral mucosal disease, temporomandibular joint disease, bruxism, periodontal disease and so on. It was believed that these patients might be more susceptible to the impact of stress events, and dental specialists should pay more attention to them. At the same time, this paper analyzes the possible psychological stress symptoms of patients with different oral diseases, and puts forward suggestions for remote consultation and emergency treatment of dentists. From the perspective of social role, dentists not only played the role of expert in dental home professional guidance, but also played the role of psychological counseling for patients.

Objective:To investigate the curative efficacy and application value of convalescent plasma (CP)in severe and critical coronavirus disease 2019 (COVID-19) caused by Delta variant.Methods:The treatment process and results of CP therapy for a patient with critical COVID-19 caused by Delta variant were reported. The clinical application value of CP for COVID-19 caused by Delta variant was analyzed along with the literature review.Results:Our case was a 50-year-old male, who was imported from abroad and had not been vaccinated against COVID-19. The novel coronavirus nucleic acid test was negative before entry. On the second day after entry, fever occurred, novel coronavirus nucleic acid test was positive. Chest CT images showed bilateral multiple mottling and ground-glass opacity with symptoms of nausea, headache, loss of appetite, diarrhea, but no running nose, nasal obstruction, dyspnea, abnormal smell and taste. The infection rapidly developed from medium to critical. On the basis of standard treatment, Delta variant CP was intravenous dripped on the 10th day of hospital admission (the 6th day after becoming severe). The patient's condition improved rapidly.Conclusion:The curative efficacy evaluation of this patient proved that CP therapy is of great value in the treatment of severe and critical COVID-19.

Dental erosion is a progressive loss and damage of tooth hard tissues caused by contacting acidic substances. It is an occupational disease for workers who make acidic products such as acids, vinegar, etc. In the past decades, a rising of prevalence rate of dental erosion, especially in the youth groups, along with the change of dietary habits and the increased consumption of sweet and acidic diets, has attracted public′s attention. This article reviews and analyzes the literature on the prevalence, etiology, prevention and treatment of dental erosion, so as to provide guidance for early diagnosis and treatment of dental erosion and support for making occupational disease prevention strategies.
