The term complication is defined as a secondary disease, an accident, or a negative reaction occurring during the course of an illness and usually aggravating the illness. It usually takes two forms: a secondary illness of a disease; or a complication resulting from medical treatments.Characteristic of being risky, predictable, uncertain, and relatively avoidable, complications are affected by a variety of factors. In the course of identifying medical malpractice, identification of complications should be achieved according to how complications occur and evolve in the entire course of treatment and care, whether staffs have followed standards and regulations for treatment and care, whether staff are well aware of their obligations to take precautions to avoid risks, and provide medical care once complications take place, whether malpractice exists in the practice of medical staff, whether a cause -effect relationship exists between complications in patients and harms caused to families and medical malpractice.

The mechanisms of antidepressants are still unclear. There a re two classical theories on monoamine neurotransmitter or on neurotransmitter rec eptors, but both of them can not fully explain the delayed therapeutic action of antidepressants. Recently, many researches have focused on the postreceptor int racellular signal transduction as the mechanism of antidepressant action. G protein is the molecular basis of antidepressants. Neurotransmitter receptors and G protein are the two sectors of their therapeut ic action. They will ultimately influence intracellular signal transduction and result in relative effects such as phosphoration, the induction of neurotrophic factors and neurogenesis. This mechanism suggests a reasonable explanation for t he clinical delaying of antidepressants and it will do great help for the develo pment of antidepressants. It makes the design of novel, safe and more efficaciou s antidepressants possible and provides significant information for the elucidat ion of biology of depression.

Objective To investigate the emergency treatment and correlation factors of aqueous misdirection during glaucoma and cataract surgery in glaucoma patients.Design Retrospective case series.Participants 126 cases(132 eyes)of angle-closure glaucoma patients with aqueous misdirection during surgery,100 cases(100 eyes)of angle-closure glaucoma patients without aqueous misdirection during surgery and 100 cases(100 eyes)of senile cataract patients.Methods We performed pars plana vitreous water-bag aspiration or anterior vitrectomy on glaucoma patients with aqueous misdirection during surgery.All the factors in observation group and control groups were compared and analyzed by logistic regression.Main Outcome Measures Preoperative highest intraocular pressure(HIOP),intraocular pressure after maximum dose(IOP),anterior chamber depth(ACD),lens thickness(LENS),axial length (AXL),mean keratometry(K),intraocular lens diopter within-0.5D corrected by SRK-T formula(IOLD).Results Among all the 132 angle-closure glaucoma eyes whose posterior chamber pressures were increased during surgery,we performed pars plana vitreous water-bag aspiration in 123 eyes(93.18%),and anterior vitrectomy in 9 eyes(6.8%).Postoperative complications included shallow anterior chamber in 20 eyes(7 eyes with malignant glaucoma,9 eyes with choroidal detachment,4 eyes with delayed local suprachorodal hemorrhage),and vitreous local hemorrhage in 1 eye.Means of all the observation indexes on three groups showed significant difference(all P

Objective To explore the levels of neuron-specific enolase(NSE)in serum and cerebrospinal fluid(CSF) of children with convulsion,and its significance to the diagnosis of neuronal damage was evaluated.Methods Sixty patients were enrolled,and they were divided into 4 groups:non-nervous system disease group,peripheral nervous system disease group,brief convulsion group,and prolonged/status convulsion group.The levels of NSE in serum and CSF were detected in 4 groups,and the electroencephalography(EEG) and computed tomography/magnetic resonance imaging(CT/MRI) examinations were taken to observe the changes in patients with convulsion.Results The levels of NSE in serum and CSF of children with convulsion increased significant,especially in the prolonged/status convulsion group.Changes of NSE levels in serum and CSF were similar.Meanwhile,significant changes were found in EEG between the brief convulsion group and prolonged/status convulsion group;but no significantly changes were found in CT/MRI between the 2 groups.Conclusions NSE detection might be valuable to the diagnosis for neuronal damage in early time.The changes of NSE levels are similar to those in EEG,which are more sensitive than the changes in CT/MRI.It is very important to combine the NSE detection in serum or CSF and EEG examination in early time after convulsion for judgement to the neuronal damage and prognosis.

BACKGROUND: It is very important to explore an optimal loading force that can both allow effective intrusion and cause no damage to the teeth.OBJECTIVE: To investigate the optimal loading conditions, including loading force values and directions, in the intruding mechanics of maxillary anterior teeth.METHODS: A three-dimensional finite element model (3D FEM) of the maxillary anterior teeth was constructed to include the periodontal ligament (PDL), alveolar bone, and appliance (brackets and wire). The initial stress distribution and force of the maxillary anterior teeth were analyzed when the 3D FEM was loaded with different intruding force values and directions. RESULTS AND CONCLUSION: The optimal value of the intruding force for 6 anterior teeth fell within the range from 0.5 N to 1.0 N. The maximum stress was detected at the distal cervical level of the lateral incisor, and a relatively even distribution of initial stress was observed at 20° palatal deviation to the Y axis. The results suggest that using mini-screw implants at the labial region between the canine and lateral incisor and a combined 0.5-1.0 N intruding force with a distal force could be an optimal intrusion force system by which patients with normal occlusion could obtain a pure intrusion of anterior teeth.

Objectives To study the changes of hard tissue before and after orthodontic treatment for Angle's class Ⅲ malocclusion adolescence patient with maxillary front traction. Methods 20 cases of Angle's class Ⅲ malocclusion adolescence patients were treated by front traction in maxilla, while there were 20 cases of Angle's class Ⅰ malocclusion adolescence patients as the control group. Cephalometric a-nalysis was carried out before and after the treatment. Data were analyzed by SPSS11.0 system using paired t-test. Results There were significant increases in the length, anteroposterior diameter and thick-ness of maxillary sinus (P<0.05), while there was no significant differences in the site and central point of maxillary sinus(P>0.05). Conclusions It is a effective approach to change the hard tissue after ortho-dontic treatment for Angle's class Ⅲ malocclusion adolescence patient with front traction in maxillary area.

Objective To investigate the effects of Xuebijing injectio (Chinese herb preparation) on intestinal function and inflammatory responses in severe burn patients. Method Thirty-two patients with comparable severity in burn injury were randomly divided into Xuebijing injectio treatment group (n = 16) and control group (n = 16). Patients in both groups received routine burn therapy, while those in Xuebijing treatment group additionally received Xuebijing injectio 100mL in intravenous drip twice a day for 7 days. Before the treatment and on the 3rd and the 7th day after the treatment, blood concentrations of diamine oxidase (DAO), lipopolysaccharide (LPS) ,tumor necrosis factor-α(TNF-α) and interleukin-6 (IL-6) were determined in both groups. Analysis was made by SPSS 12.0 software. Results The plasma levels of DAO, LPS, TNF-α and IL-6 were decreased in both groups after the treatment. However, the plasma levels of DAO, LPS, TNF-α and IL-6 in the Xuebijing treatment group were significantly lower than those in control group on the 3rd and 7th day after the treatment (P＜ 0.05).Conclusions Xuebijing injectio could protect intestinal function, decrease the plasma level of endotoxin and lessen zhe inflammatory responses in severe burn patients.
